Working in the Shadows Ch 4

Justin Falcone October 19,2012 Homework # 5 Chapter # 4 Journal In reading chapter 4 in working in the shadows we have seen that Gabriele is on his last week of training. Gabriele is giving the job to cut the four rows of lettuce that are in the path of the machine where the lettuce is stored in the boxes. Gabriele is realizing that 4 rows is a lot and his has to get them done. In this chapter you as the reader really realize all the courage, ambition and strength that Gabriel has. Gabriele has started cutting the lettuce the first day Gabriele couldn’t cut 25 heads before having to stand straight up and relax and stretch his back.Gabriele stayed strong and kept up with his cutting and as the days went up Gabriele has cut thousands of lettuce and was on his way to finish up his rows. In this chapter it tells us that Gabriele starts working with the rest of the group and tells us all the struggles that Gabriel is going threw. Between the aches and pains and the soreness, Gabrie l needs to stay strong, it really allows us as the reader to wonder how hard these immigrants are working. As Gabriele goes on with his workdays no matter how hard he is working he is getting yelled out to work harder even though he believes that he is keeping up with the rest of the workers.Something that caught my eye that I feel this chapter was manly about was the immigrant worker towards the American workers in the United States. On a Sunday morning Gabriel went to visit Mateo, and the comments Mateo where making for me as an American worker in the United States take it personal. Basically trying to say that Mexican and immigrant workers work much harder where they work in there country, and that us Americans only sit in offices and work on computers all day.Something that was left out in this chapter could have answered these comments for me and for Mateo that we as Americans work harder then these immigrants think we do. Gabriele could have given stories or even experiences h e had with working to back up us Americans. At least explain that the reason why immigrants get into the United States and take the labor jobs from many American workers is because immigrants allow the low pay and the extra hours of work, because it isn’t anything new for them.As seen in lettuce picking with the extra hours and the low pay, these immigrants don’t have a choice they need to take these jobs. Towards the end of the chapter Gabriele is explaining how hard this job is for him, one of the hardest and Gabriel has taking 2 days off to relax his body. This job I making Gabriele dream about it that how much he thinks about it and worries about going to work every day. After all in my eyes Gabriel realizes that this job is putting a number to him, but he will not quite, he will work threw pain and suffer no matter what.

Law and Ethics, Patients Rights in Practice Essay

In particular, those aspects observed by the student relating to patients privacy, confidentiality and any situations which warranted a limitation to patient privacy will be described and discussed with reference to patients rights. Situations in the hospital setting where the student nurse viewed health professionals informing patients about treatment options, encouraging patients to take action in decisions about their health, and gaining informed, voluntary consent prior to procedures will be discussed. An explanation of reasons for selecting privacy and consent as two essential concepts which health providers must understand will be illustrated. The legal and ethical responsibility of health care providers in relation to the aforementioned fundamental principles of achieving patient privacy and gaining informed voluntary consent will be examined with a clear emphasis on patient’ rights. While on clinical placement, the student nurse observed health professionals maintaining patient privacy to a high standard by consistently shutting curtains around patient’s beds, lowering their voices when working with patients in rooms containing multiple beds, courteously requesting visitors to leave the room when procedures of a sensitive nature were preformed and closing patient’s doors to limit unwanted interference from hallways. In order to show patients respect, dignity and consideration, which are outlined as a fundamental patient right in the Queensland Health Public Patient’s Charter (2002), patients were consistently examined in areas that were as private as was possible at the time. This attempt by health care providers to maintain the physical privacy of all patients by consistently minimizing unwarranted outside attention is a clear demonstration of how health care providers maintained patient dignity, consideration and respect. According to the Ramsay Health Care/Cairns Private Hospital Patient Charter (nd. , patients have a right to be treated with courtesy throughout their hospital experience. The actions of the health care team correlate positively to this statement as through the maintenance of patient’s physical privacy, health care providers are demonstrating consideration for their patients and respecting their rights set forth in both the Queensland Health public patient charte r and the Ramsay health care charter. Throughout the clinical placement of the student nurse, the health care facility in question demonstrated exceptional adherence to national privacy principles 4. set forth in the Privacy Amendment Act (2000). Initiatives currently in place at Cairns Private Hospital ensure confidentiality of both patient’s medical records as well as patient’s personal details by limiting outside access to confidential information and preventing health care professionals from transmitting such information to the broader community. One such example observed by the student nurse involves the hospitals policy preventing nurses from leaving the hospital with materials used in nursing handovers that contain information regarding patient’s condition and personal details. The destruction of such material prevents the transmission of private information to the wider community and demonstrates the role of health care providers in maintaining patient privacy. According to the national privacy principle 4. 1 extracted from the Privacy Amendment (Private Sector) Act (2000, p. 9), â€Å"An organisation must take reasonable steps to protect the personal information it holds from misuse and loss and from unauthorised access, modification or disclosure. Therefore, by ensuring patients information is protected from unauthorised access and disclosure, Cairns Private Hospital is fulfilling the legal obligations set forth for private organizations in the Privacy Amendment Act (2000) principle 4. 1. Patient’s right to have their personal information kept private and confidential, as outlined in the Queensland Health Public Patient’s Charter (2002), was also exceptionally demonstrated by those nurses with whom the student nurse was in contact during c linical placement. Health care providers consistently maintained patient confidentiality by limiting discussion of patient’s condition to those situations where health care providers must share patient information to improve patient care. When the student nurse observed an exchange of information between health care providers pertaining to patient’s condition, it occurred in a manner such that other patients or visitors were unable to discern the content of discussion. This includes, but is not limited to, patient information related in nursing handovers. By treating patient’s personal information obtained in a professional capacity as confidential, nurses are adhering to the expected national standards for Australian nurses as stated in ANC Code of Professional Conduct for Nurses in Australia (nd. ). The importance of maintaining patient privacy is unquestionable. Patients belief that health care professionals will handle their personal information with respect, dignity and maintain their confidentiality not only illustrates the ethical and legal responsibilities of health care providers, but correlates positively with the formation of trust between patient and nurse. According to Stein-Parbury (2005 p. 42), â€Å"†¦ without trust, there is minimal self-disclosure and little chance that patients will share their experiences with nurses or that nurses will come to understand patients’ experiences. † Therefore, through the maintenance of patient privacy and confidentiality, the element of trust, which forms the basis of all nurse-patient relationships, is strengthened. Crisp and Taylor (2005), illustrated the importance of patient privacy and confidentiality as without these two essential components patients would not feel able to tell health care professionals their most intimate and private details. This potential hesitation to share personal information with health providers can have a negative impact on the provision of care and can ultimately lead to treatment that does not take into consideration essential aspects of patient’s health. The maintenance of patient’s privacy is essential in both building trust between nurse and patient and providing holistic nursing care. As stated previously, the maintenance of patient privacy has implications in both legal and ethical spheres and is paramount to the formation of the nurse-patient relationship. Student nurses must therefore gain an understanding of the importance of maintaining patient privacy to ensure that once qualified as a registered nurse, one will understand the reasons why legally and ethically we must adhere to the guidelines. In today’s health care setting, the emphasis of patient’s rights and understanding these rights is paramount if one wishes to practice safe appropriate care for all peoples. It is for these reasons that the central issue of patient privacy was selected for consideration. Although the importance of maintaining patient privacy is unquestionable, there are ertain situations that warrant the sharing of patient information. As observed by the student nurse, health care professionals continuously share patient information between themselves in attempts to allow allied health professionals to provide appropriate holistic patient care. In today’s hospitals, with shift work and the increasing specialization of various allied healt h workers, it is essential that patient information is shared to improve patients care and outcome. In order to achieve appropriate care for patient’s, this is a requirement and will not be considered as a breach of patient privacy. This team work approach to health care is viewed as of benefit to the patient and is absolutely essential is today’s health care facilities where health care professionals are increasingly working in more specialized fields. Throughout the entire clinical placement, the student nurse consistently observed health providers informing patients of their various treatment options, encouraging patients to take an active role in decisions about their health, and ultimately gaining informed voluntary consent prior to any procedure. As outlined in the Queensland Health Public Patients Charter (2002), and the Ramsay Health Care/Cairns Private Hospital Patient Charter (nd. ), patients have a right to easy to understand information about their condition, treatment options, risks, and expected outcomes. The health providers viewed by the student nurse exemplified exceptional adherence to the patients right to accurate information as nurses were observed directly informing patients wherever possible about their treatment options, risks, and choices available to them. Health care providers not only adhered to their legal obligation of providing treatment information to patients, but did so in a way that reflected nurses ability to use due care in support of their ethical responsibilities. According to the Ramsay Health Care/Cairns Private Hospital Patient Charter (nd. ), patients have a right to ask questions and seek clarification in regards to matters that concern them. The actions of the health care team exemplified good practice with reference to this patient right. Health care providers were willing at all times to respond to patients questions or concerns and faced each situation with enthusiasm and clear respect for patients right to ask questions and seek clarification. Patients right to take part in decisions about their health care as stated in the Queensland Public Health Charter ( 2002), was viewed by the student nurse to occur in conjunction with the aforementioned patient right to information about treatment. By providing patients with easy to understand information about their condition, it allowed patients to make informed choices regarding their treatment and overall health. Health professionals were observed to provide patients with the information they require such that patients could make their own decisions regarding their treatment options. By thoroughly providing patients with necessary information as well as encouraging patients to take an active role in decisions about their health, health providers were empowering patients and fostering patient’s autonomy. Autonomy, the freedom to decide and act (Stein-Parbury, 2005), can be enhanced when a patient is given information about their condition and encouraged to take an active role in making decisions about their health. Informing patients of various treatment options and encouraging patients to take an active role in decisions about their health are fundamental components of informed voluntary consent. Informed voluntary consent may be implied, written or verbally given. The student nurse observed various nurses obtaining implied consent from patients when performing routine procedures such as taking a blood pressure reading. The student also viewed health providers obtaining verbal consent from patients when preforming procedures such as showering and mobilizing patients. The health providers adhered to the legal requirements which state that consent must be voluntarily given and informed (Forrester & Griffiths, 2005). The actions of the health care team correlate positively to the statements set forth in both the Queensland Health Public Patients Charter (2002) and the ANMC Code of Ethics for Nurses in Australia (nd. ). The charter asserts that patients have the right to give their permission before they are treated. Whether consent was implied or verbal, the student nurse observed patients giving their permission prior to any procedure. According to Value Statement 2 in the Code of Nursing Ethics (nd. ), nurses must accept the rights of individuals to make informed choices in relation to their care. By ensuring that patients right to make informed choices in relation to their care and obtaining informed voluntary consent, health providers are meeting their legal and ethical obligations surrounding patients consent. It is essential that student nurses have an understanding of their moral and legal requirements surrounding patients consent. If a health provider performs a procedure without acquiring consent, there is a possibility that their actions legally may amount to assault or battery. According to Forrester and Griffiths (2005), battery involves the unlawful touching of a person without his or her consent. In charges of battery, there is no requirement that the patient sustains any injuries as a result of health professionals unlawful touching. Health providers must therefore have an understanding of the legal ramifications surrounding consent to ensure that they provide safe nursing care based on respecting patient’s legal rights. It is for this reason that the issue of patient’s consent was included for discussion in this paper. It is becoming increasingly important for health professionals to have an understanding of their legal and ethical responsibility for the maintenance of patient privacy and obtaining informed voluntary consent prior to preforming any procedure with patients. With the emphasis on patiens rights becoming more prevalent in the health care setting, it is essential that health care workers respect patient’s rights which include, but are not limited to, maintaining patient privacy and obtaining informed voluntary consent. The health providers present at the health care facility attended by the student nurse were observed to demonstrate good practice with respect to patients’ rights as set forth in the Queensland Health Public Patients Charter (2002).

(FAR) Quality Assurance Research Paper Example | Topics and Well Written Essays - 750 words

(FAR) Quality Assurance - Research Paper Example An implied warranty automatically protects the government upon the sale of an item, unless it is overridden by a disclaimer. An implied warranty of merchantability ensures government purchases items of good (average or above) quality and fit for an ordinary purpose intended for, while an implied warranty of fitness protects the government against unsuitable services or products for a specific purpose, known to the recommending seller of the item. Keywords: Defective Products, Items, Contract, Warranty, Acquisition, FAR, Disclaimer, Liability, Cost Determining Criteria to invoke a Warranty in FAR Contracting officers of the government have a crucial role to play, especially in considering commercial practices in handling contracts between the government and contractors, for a smooth exchange of the commercial items or services. Considering the various defects or gross mistakes that may arise in the provision of the commercial products, even though warranties are not compulsory in thes e contracts, such challenges push for the need of the warranty in specific acquisitions. According to the FAR part (46) section (703), contracting officers assess the nature and use of the services or suppliers, trade practices, administration and enforcement, cost, and reduced requirements to determine the appropriateness of a warranty for an acquisition in a contract. Warranties are an extension of the standing relationship between the contractors and the government, but also extend the liability cost to one of the parties based on the matters that may arise from the contract. Similarly, warranties support inspection and acceptance practices in quality assurance of the contracts. When an analysis of the above factors is conducted and the need for a warranty in a specific acquisition found, then in the best interest of the government, a warranty clause can be used. The government acquires the warranty when it is cost effective. In any case, the government would want to reduce the b urden in maintenance, use or operation, and additional costs that may arise due to potential undetected defects. That is why such factors like difficulty in detecting a fault prior to acceptance, assessing potential harm to the government in case of a defect, complexity and function of a an item or service, end use, degree of development, and state of the art under FAR 46.703 part (a) have to be evaluated. The arising costs coming from the deferred liability on the contractor’s side and warranty enforcement of the government’s side, extended trade practice in the cost of a warranted item to the government, the ability of an assured administrative system to report on discrepancies, and reduced government quality assurance requirement would necessitate the government to include a warranty. Through the procedure, the government would ensure that the non conformance is covered in the warranty clause of the contract. Protection against Defective Services Express Warranties They frequently characterize the majority of the government contracts. Some can be complex, but are often specific to service contracts. These warranties can be oral or written, but for official purposes to the government, a written form is often common as a claim for its existence and avoiding chances of contractor’

Concepts and Processes of marketing segmentation, Targeting and Essay

Concepts and Processes of marketing segmentation, Targeting and Postitioning - Essay Example Pricing of a product depends on various variables before the product is taken to the market. In marketing people try to maximize profits which makes it very important for prices to be determined before the products are taken to various markets in the different geographical areas. The prices can also be different depending on the demand of the product being marketed and their utility. The place or the destination of the product is the third P of marketing. Marketers have to monitor and evaluate the places where the products will be more appropriate and which segmentation will ensure that their marketing strategies will be useful and worthwhile. The last P of marketing explains the promotion strategies of the product. Promotion depends on various products and the marketers expectations of the same. Some products maybe more promoted than others because human beings have a unique taste of products thus promoting a variety of products increases the chances of the products selling of faste r than those that are not promoted (Sengupta, 2005). The Marketing Process The marketing processes vary from one different nation around the world to the different types of products being marketed in the same. Marketing over the years has improved from being a door to door operation to something that has expanded to internet activities occurring on a 24 hour basis. Today Nokia mobile phones are being marketed in every corner making very easy for clients to learn about the product its services and other features that make it superior to other types of phones (McDonald, 2008). Various companies including Nokia mobile phone manufactures have decided to go digital with their marketing strategy with their main aim being to maximize their sells of the products as well as be able to maintain their customers loyalty. Marketing is about giving knowledge to the world about a company’s product, like why the Nokia products are better than other phone producers, why the clients should dec ided on settling on Nokia product and stick with it, the benefits of the Nokia products especially the phones on the short term basis as well as the long term and where the product best fits to be used. Marketing does not necessary reflect the product profit margin, but how well the product can be identified by various people around the world and the impacts it gives to various communities. Marketing is about selling the brand to as many people possible, giving details on any changes if about the product, updating customers on prices and the nearest stores they can access the products (McDonald, 2008). Marketing is about promoting a product to gain customers trust and liking to other manufacturer’s products that produce the same kind products. The more resources a company uses to market its product the better chances the company may be able to sell their product to a larger segmentation. Market Orientation and a Brief Description of Different Orientations That Could Be Adopte d Marketing orientation can be defined as companies, organizations or firms reacting to the customers’ demands and the next products they produce will be to fit majority of the customer’s specifications. The decision for market orientation is based on the customers feedback and the companies concentrates more on the customer’

Langston Hughes Essay Example | Topics and Well Written Essays - 2250 words

Langston Hughes - Essay Example Langston's sensitive nature was also responsible paradoxically in reinforcing his sense of separateness as a Negro. He acknowledged his race to be clearly an advantage, which gained him fame and recognition not only among his peers but also among those towards whom he was subjected towards color sensitivity, as it was his color that acknowledged and helped him in seeking his own identity in revealing the black experience. Langston Hughes was aware of the fact that being a black, his race would never be granted permission to gain access in participating in any effort towards America. He wanted the blacks to awake from the long sleep and start making the dream of their homeland a reality, although it was the dream which according to Langston was converted into a nightmare for Southern blacks, he aimed at rehabilitating that nightmare again into an American dream. No doubt Langston Hughes was among one of those renaissance writers who produced little work on Harlem, but whatever they produced, the work emerged as a magnum opus in the Harlem Renaissance history and produced a true Harlem color. Langston Hughes, the Harlem writer was especially adept at portraying New York's ghetto life concerning about people, culture and religion. What he experienced during the renaissance enabled him to portray the true face of white Americans and in the form of words he described it. Langston's work about Harlem reveal his versatility as wh... ons African Americans had to face regarding social and economic factors of Harlem, he found a ready market among some blacks who wanted to read about life in the black metropolis on one hand, while on the other he was aware of those whites who were attracted to the exotic, strange, and colorful rhythms of 'nigger heaven'". (Wintz, 1988, p. 45) Harlem, though, was more than a playground for white Manhattan, for Africans it was more than a battle. A battle conducted not to loose, but to win and make whites acknowledge their identities as African Americans. "It was a teeming, overcrowded ghetto, and much of its laughter and gaiety only thinly veiled the misery and poverty that was becoming the standard of life for the new black urban masses. This, too, was reflected by the Harlem Renaissance, viewed from the perspective of Langston". (Wintz, 1988, p. 46) "Langston portrayed the outbreak of World War I as the only means, which intensified racial conflicts in America. He was aware of the sacrifices given by every single African of America and realized the importance of African traditional people in supporting America's war, with a hope that their efforts would display one day a result of loyalty and battlefield gallantry to win them popular support in their quest for equality". (Rampersad, 2002, p. 54) Langston encouraged their efforts to participate fully in their country's battles; blacks have traditionally confronted a government reluctant to accept their services. During World War I the already existing racial strife intensified these problems. Some poets saw Harlem slightly different as compared to other poets of Renaissance in a sense that unlike many would be black writers; Langston Hughes was strongly drawn to the black people of Harlem, which won the hearts of

Dynasty Essay Example | Topics and Well Written Essays - 500 words

Dynasty - Essay Example ty came to an abrupt ending because of its expensive military expansions and political unrest due to its autocratic and tyrannical form of government. Though principles of Confucius were respected and followed to some extent in state affairs but more emphasis was paid on Buddhism and Taoism. Education system was over-hauled. Civil service exams were introduced a long time back during the Han dynasty and during this time period, this system was revived. The economy of China improved due to developments and engineering works such as canals, roads and cities- which were undertaken on a large scale. Special attention was paid to irrigation and agriculture. The Grand Canal was built to promote speedy communication and transportation between the northern and the southern parts of China. The Great Wall of China was also fortified. 1 In 617, the Sui dynasty was overthrown by Tangs. It promoted Taoism in the religious and social lives of the people. The government was centralized and it managed to rule for about 300 years. Major changes in the political, economical and social structures were witnessed during this time. Printing was invented and Art and literature flourished. Arab, Persian and foreign traders expanded their activities during the eighth century and set up factories at the Canon Delta, Fu-chien and Chiang-su2. The government held large areas of land particularly for the breeding of horses for the government officials; and military-agricultural colonies were established along the northern border as a means to protect the frontier3. The Tang dynasty managed to establish peace and stability in the empire and during 715-56 AD, prices were low and merchants could undertake long journeys without the fear of robbery.4 Transport of luxury goods and grains from the southern parts of China was made easy with the intricate web of highways and the canal system.5 This state of wealth and prosperity could not last longer because land holding policies of the government

Conserving Soil Quality On Farms In Hawaii Research Paper

Conserving Soil Quality On Farms In Hawaii - Research Paper Example By the time measurable damage to the soil quality has occurred, crop yield may already be irrecoverably failing (Stocking, 2003). This relationship can even hold true in areas that with volcanically-enriched soil such as the tropical islands of the state of Hawai'i. To understand soil conservation for farming in Hawai'i, the first step is to understand the background of soil quality conservation, with a focus on the issues specific to the tropical islands. Only then can workable solutions be found and analyzed for suitability to the specific situation found on the Hawai'ian islands. A clear definition of soil quality is necessary for a conservation project to be undertaken. Unless soil quality is clearly and definitively described, it is impossible for researchers to design tests and measurements to study the current state of the soil quality. However, soil quality has proven a very difficult concept to define, especially as soil quality has so many different parameters in many diffe rent spheres of scientific study. Defining soil quality as a term is not the same as defining other widespread environmental terminology such as air quality or water quality. This is due to the fact that air quality or water quality are not based on the usage of the material or its relationship relative to a â€Å"natural† state, but merely on the lack of specific pollutants or on the levels of such pollutants (Sojka & Upchurch, 1999). Since pure soil cannot exist by definition, and clean soil varies dependent on location, pollutants within soil can be limited only to specific non-natural products, such as industrial wastes or household chemicals (Cowan & Talaro, 2006). Soil quality, on the other hand, is determined by the soil's ability to support certain usage and by healthy levels of bacterial, animal, and plant life (Sojka & Upchurch,1999). Measuring soil quality in tropical regions, on the other hand, is simplified because of the reduction in the number of related variab les. Many attributes of topsoil quality in tropical regions of the world, including Hawai'i, are quantitative and measurable. Assuming those conditions to be true, soil quality can then be measured using a fertility capability soil classification system (Sanchez, Palm, and Buol, 2003). Other single-attribute measurements of soil quality are such concerns as soil compactability or erodibility based on location or use, but the fertility classification most affects the ability of the soil to support intensive crop farming, which is the concern of this review (Parr et al., 1992). The fertility capability classification systems are not without their faults, but they provides a starting point for measuring the success of a given conservation program by providing a quantitative standard. A measurement that makes use of this system would be comparable to future measurements under the same system, allowing a researcher to compare numerically the success of the method under study (Sanchez, Pa lm, & Buol, 2003). Soil systems in tropical regions tend to be extremely dynamic, changing rapidly over short periods of time. Within these systems, soil quality may vary widely from location to location even between patches of soil in the same forest (Parr et al., 1992; Stocking, 2003). In such a dynamic system, nutrients rarely have time to accumulate in the tropical

How do unemployment, under-employment and discouraged workers affect Research Paper

How do unemployment, under-employment and discouraged workers affect GDP in an economy - Research Paper Example The second one that is known as underemployment occurs when workers underutilize their skills in their current employment, and the last one takes place when individuals stop finding jobs because they are discouraged with their fruitless effort of finding one (Thompson 78). All these forms of unemployment lower the Gross Domestic of a country. This paper will analyze how unemployment, discouragement, and underemployment lower GDP. First of all, when individuals finish school, they start seeking employment in the labor market. Some become lucky and get jobs while others remain on the search. The state refers to those who fail to get employed at the existing wage rates as the unemployed. These individuals continue depending on their parents for funds that help them to survive and continue with the job search. The unemployed may also depend on their friends who were lucky to get jobs after school. This further increases the dependency ratio in the economy. This means that the individuals, who support the unemployed by giving them funds, reduce the amount of income that they save and invest (Thompson 81). They instead increase the amount of money that they set apart for consumption. The reduction in savings means that these individuals earn less interest than they used to earn before. The reduction in interest rate then means that they earn less income from investment activities and this reduces the overall incom e of a country. The effect of this unemployment is based on Okun’s law that states that a 1% increase in the rate of unemployment leads to a 2% decrease in the GDP (Boyes and Michael 226). The other form of unemployment takes place when workers discontinue their job search because of hopelessness. These individuals lose hope based on the belief that they will never secure a job in the labor market at the existing wage rates. The loss of hope makes these individuals to either continue depending on their relatives and friends or engage in

Popol Vuh Creation Essay Example | Topics and Well Written Essays - 250 words - 2

Popol Vuh Creation - Essay Example This relates to agriculture because of the three attempts, corn is the only one that brings life, when planted properly. The story somehow showed analogy of man having soul and seeds bringing life to agriculture. The belief in religion is also a good lesson from the story. The story showed the existence of different worlds, the underworld, upper world and the world we know as Earth. Religion teaches human beings to believe in the existence of Gods, and worship the Gods who created them. The third lesson was about the trails that the Hero Twins had to go through to be able to get their father from the gods of the underworld. They used magic and trickery to defeat the gods. After doing so, they were rose up to the upper world and became the sun and the moon. Their love for their father and their perseverance showed that they were worthy to be exalted op to the upper world and be with the Creator. The connections between all living creatures on earth shown in the Popol Vuh can still be related to how Mayan society value the plants and animals around them. Corn, being an agricultural product, has been a representation of the human body and soul. The teachings from the story of the Hero Twins help the Maya society accept death and trials as their challenge to be able to climb up to where the Hero Twins are. From the underworld, their success will help them gain a worthy place together with the sun and the moon. This story teaches us that even if societies have different stories of creation, the existence of a Creator, the interconnection of life on earth, and the battles that we go through to be able to deserve a good life in heaven, are almost the same in context. This also shows that no matter how different the religious beliefs are, the teachings behind them are all for the common good of the

The 2010 Annual Report of PSA Peugeot Citroen Essay

The 2010 Annual Report of PSA Peugeot Citroen - Essay Example AMF is the French regulator or the counterpart of Securities and Exchange Commission (SEC) in the US. Its role therefore in the development of financial reporting in France would be the same as SEC. It is tasked along with SEC to develop principles on cooperation in the supervision of markets and market participants whose operations cross international borders (Casey, 2010). In the US, SEC adopts the issuance of FASB’s on accounting standards on financial reporting and so with the same reason that AMF will give the legal force by accounting standards set by the standard-setting board in France. The AMF was established with the task of ensuring or protecting public savings invested in financial instruments as well all other investment that would result or metalize in a public offering. It also has supervision of the prepared financial information as conveyed to investors. It has, therefore, is the purpose of effectively promoting the proper running of financial markets. Its contribution to France regulation of these markets extends in European and international level (International Monetary Fund, 2005). The European Union’s Fourth Directive allows four income statements format. Explain the structure of PSA Peugeot Citroen’s income statement on page 204 in terms of the options allowed under the Fourth Directive and IAS 1. In addition to AMF, the European Union’s Fourth Directive can affect how PSA should present is financial report to users. The said directive, in particular, allows four income statements format. Explaining the structure of PSA Peugeot Citroen’s income statement on page 204 in terms of the options allowed under the Fourth Directive and IAS 1 could give an insight how to interpret PSA’ financial statements for 2010. The structure of the company’s income statement on page 204 appears to be consistent with options allowed under Article 25 of the Fourth Directive of the EU (EUR.Lex, 2011). The format under Article 25 starts with turnover, which must be reduced by the cost of sales, to get the gross profit loss.  

Technologies vs Traditional Skill Essay Example for Free

Technologies vs Traditional Skill Essay The traditional skills seems to be forgotten and dying due to the betterment of technology. The enhancement of technology improves the quality of life in the aspect of education, medication, and communication. The advantages of the improvement of technology can be seen in the field of education. The advancement in technology helps the students in their learning. The use of technology like projector in class makes the learning fun and easy to be understood by the students. In some schools, they use e-learning as a medium for the students to easily accessed to their teachers and learning. Now, a teacher does not need to use chalk and wasting their energy to write on the blackboard. Another contribution of the development of technology is in the aspect of medication. The body of a person can easily be analyzed by using the x-ray technology, microscope, scanners and many others. The revolutionized medicines and surgical tools make the treatment and surgery become less painful. The treatments become more efficient and many health problems can be cured easily. Lastly, communication is no longer limited because of the development of technology. In the past, people wrote and sent information through letter and telegram, which requires a long time to be received by the receiver. But now, information can be sent and received just by a click. Whether it is emergency services, friends, family or work related issues; we now have cell phones, PDA’s, email, and other ways of electronically transferring information we need to communicate for whatever reason. To sum up, there is no need to retain the traditional methods as the advanced technologies have already made the life ultimately easier.

Process Management Methods for Construction Performance

Process Management Methods for Construction Performance ABSTRACT The purpose of this research was to study how the construction performance can be improved by adopting the process management approaches, in order to provide better client value and more cost-efficient production. The research focused on the manufacturing process , and referring point, and transfer this process thinking into the construction. The methods were tested in pilot tests in which the developed cost and value engineering prototype application was used. This thesis demonstrates an integration of design and production planning based on the product model approach. The final outcome is that the main contractor can utilise information coming from designers as input in its own tendering and cost estimation applications. The key methodology used for describing the information management process throughout the building process life-cycle was IDEF0. The analysis of the current process (as-is), in the form of an IDEF0 model, helped in identifying the main problems of current practice. The target process (to-be) definition was based on product model utilisation and takes into account the possibilities for process reengineering supported by product data technology. One specific requirement was deemed important in view of the anticipated developments in thearea of data exchange; the target system should be structured in such a way that it could easily be adapted to receive data according to the emerging IFC core model schemas. The overall result of the research reported in this thesis is that the product model approach can be used for a substantially reengineered information management process of a main contractor, especially in design and construct type contracts CHAPTER ONE: INTRODUCTION RESEARCH BACKGROUND The construction industry is suffering from its fragmented nature ¼Ã‹â€ European Commission, 1994 ¼Ã¢â‚¬ °. The lack of co-ordination and communication between parties, the informal and unstructured learning process, adversarial contractual relationships and the lack of customer focus are what inhibit the performance of the industry (Latham, 1994; Egan, 1998). Because the construction project is regarded as unpredictable in terms of delivery time, cost, profitability and quality, the industry has not been able to combine high quality with productivity, customer satisfaction and flexibility (Fairclough, 2002). Howell (1999) pointed out that the ‘inefficiency’ of the industry has tended to be the way of life. However, Latham (1994) suggests using the manufacturing as a referencing point and transferring the practices and theories from manufacturing industry. And Howell suggests that the learning from manufacturing could be a two way process: manufacturing could learn from construction in areas such as project-based management; and construction could learn from manufacturing’s developed and developing solutions to improve competitiveness. In manufacturers are accustomed to taking a process view of their operations, and they usually model both discrete product activities and holistic high-level process both internal and external activities. Base upon this, Egan (1998) recommends that process modelling could be used as a method to improve the construction performance. Furthermore, many other models derived from manufacturing and process management theories have been recognized and adopted by construction companies Nevertheless, as Ball (1988) summarised, construction industry has distinctive characteristics differentiating from other sectors as well as manufacturing. Although solutions have been recommended, their implementation in manufacturing is far advanced in comparison to construction industry. Thus to what extent these process management approaches and models can improve the design and construction process will need to be examined. RESEARCH AIM The aim of the research is to understand construction process management and to prove it as an approach that could help to improve the construction performance. In order to achieve the aim, specific objectives were set PROJECT OBJECTIVES The research project objectives are outlined below l To explore the readiness of construction to embrace the process approach to deliver project l to identify the present state of process management in construction l To Study the current trends and developments of construction process management METHODOLOGY AND APPROACH The starting point of this research is exploring the construction process management approach and find out its influence on construction productivity and competitiveness. A cross-section research method is adopted in the collection and analysing of the data and presentation of the findings. To obtain comprehensive understanding of the relationship between manufacturing process and construction process, as well as theories on construction process management, a great quantity of books and documents need to be looked through. Then the implementation of process management in construction is inspected by adoption of the case study qualitative research approach.

Chapter Six This chapter provides the conclusion of the report as well as the recommendation. The direction of further research is also proposed SUMMARY CHAPTER TWO: LITERATURE REVIEW Introduction Over the past few years, researchers and sponsors have increasingly turned their attentions to finding ways managing the construction process. After decades of neglect, construction process is high on the agenda. As the construction product has in most instances been a ‘one-off’, much emphasis has been placed on project management. However actually the industry is focused on design and development of a building product and should look to manufacturing reference on how to manage the design and development process. Examining the manufacturing perspective and understanding how it can be applied to design and construction and considering the use of techniques and technologies available to support the process and the issues relating to the implementation on projects is essential for construction industry . However, whether this process approach is needed in the construction field, and to what extent it contributes to the construction industry, this required to be researched a nd evaluated. Therefore in this project, why there should be process management in construction industry, the state-of-the-art, how it is applied and the future of it will be identified. Being continuously criticized for its less than optimal performance by several government and institutional reports such as Philips(1950) and Latham(1994), The UK construction industry has been under increasing pressure to improve its practices(Howell, 1999). From the analysis of these reports, conclusion coming up that the fragmented nature of the industry, the lack of co-ordination and communication between parties the informal and unstructured learning process, adversarial contractual relationships and the lack of customer focus are widely and typically existing in the construction industry and are supposed to embarrass the industry’s performance. Furthermore, Fairclough(2002) indicates that construction are often seen as unpredictable in terms of delivery time, cost, profitability and quality, and the investment into research and development is usually seen as expensive when compared to other industry. According to Howell, the â€Å"inefficiency† of the industry has tended to be the way of life. This may be due to the fact that none of the reports, apart from Latham (1994) and Egan (1998), has been sufficiently acted upon. So Lutham suggests using manufacturing as a reference point and Egan, in his Rethinking Construction report, recommends process modelling as a method of improvement. There has been a constant subject of discussion on the transfer of the transfer of practices and theories from other sectors as Lutham (1994) suggested in his report. Some construction practitioners are obstinate that their industry is unique and that the transference of principles cannot be adopted wholeheartedly. Due to it, Ball (1998) emphasized some of the arguments most commonly used to differentiate construction from other industries: The one-of-a-kind product. The spatial fixity of buildings. One-site production. The effect of land price on design and construction possibilities. The requirement for long life expectancy. The inexperience of clients The merchant role of company. The overwhelmingly domestic industry. The masculine stereotype of the workforce. The long cycle from design to production. The high cost of the projects. The amplified reaction to economic crisis. The labour intensive production The fragmented nature of the industry. Nevertheless, there are also many practitioners and academics who believe that the construction industry has much to learn from other industries typically manufacturing. Howell (1999) goes so far as to suggest that this learning could be a two way process: manufacturing could learn from construction in area such as project-based management; and construction could learn from manufacturing’s developed and developing solutions, to improve its performance of competitiveness and productivity. As stated by Love ¼Ã¢â‚¬  Gunasekaran (1996) and Korenlius ¼Ã¢â‚¬  Wamelink (1998), manufacturing has been a constant reference point and a source of innovation in construction for many decades. Solutions that have been recommended to help overcome the problems of construction include industrialization, computer-integrated construction, robotics and automated construction. However their implementation in manufacturing is far advanced in comparison to the construction industry. Koskela (1992) believes that the fundamental theories and principles of manufacturing should be harnessed to deliver the full benefits to construction rather than the ‘technological solutions’. In recent years the realization that the construction industry might not be as unique as was traditionally thought has initiated new research, which In particularly, has resulted in a development of the concept that construction is a manufacturing process. Moreover a research fund under the Innovative Manufacturing Initiative (IMI) sector of the Engineering and Physical Science Research Council (EPSRC, 1998) to continue and expound upon current thinking. a new phenomenon currently appears to being steadily exploited within construction companies at the side of the new technologies taken from manufacturing. It is based upon the development and use of fundamental core processes to improve efficiency of the industry, with great emphasis upon the basic theories and principles underlying the design and construction process. Egan(1998) draw attention to this factor by reporting that due to the fragmented nature of the construction industry very little work had gone into process modelling. Manufacturers are in the habit of taking a process view of their operations; they usually model both discrete product activities and holistic high-level for both internal and external activities. In particular, there has be a growing volume of research focusing upon the consolidation of the just-in-time(JIT) and the total quality management(TQM) theories, with an array of other practices such as productive maintenance, visual management and re-engineering . Investigations by construction practitioners and academics alike have now sought to develop the content and manufacturing, agile production and lean production. Current Researches on Construction Industry The Civil Engineering Research Foundation (CERT) Report observes that the construction industry is becoming frustrated over the lack of progress in removing or mitigating barriers to improving construction practices and is necessary to support sustainable development goals. the industry has to face Many difficulties as it approach this goal: facilities are designed by using least-cost technologies that ignore opportunities to improve productivity and enhance environmental quality; it seems to be complicated, to achieve agreement on government design and construction policies that advance sustainable development; what’s more, there are the frustration of knowing better technologies are available but not having the capacity o find and retrieve them; and international concentration on construction research and practice is far more inadequate. Also the report identifies specific constraints to innovation that characterize the challenges facing the construction industry which repre sent the areas where work needs to be done. The observers indicate that the design and construction process often discourage the introduction of innovative technologies and systems that have superior characteristics but are not necessarily the least-cost option, which can work to the detriment of owners and the environment; unsuitable building codes and disjointed regulatory systems that does not allow for adopting new and better materials and practices are often be applied when buildings and facilities are designed and constructed. There is a lack of understanding by the public and by industry of practices and opportunities to promote sustainable development; there is lack of timely and accurate information and a knowledge base on proven design and construction solutions and techniques for assuring quality construction, which results in lost opportunities to improve system efficiencies and productivity through adoption of innovative technologies; there are no consistent, accurate, and comprehensive predictive models available for designing for sustainability making the process difficult to validate, monitor, and evaluate. Therefore, the observers suggest, new tools and methods are required for advancing state-of-the-art technologies, including taking advantage of advances in information systems to increase the construction industry’s efficiency and productivity. According to Kraiem Diekman’s (1987) theory delays of project are classified into three groups: compensable, excusable and non-excusable. Generally, a delay is considered compensable to the contractor when its cause is within the control, is the fault of or is caused by the negligence of the owner. Excusable delays occur when the contractor is delayed by occurrences that are not attributable to either the contractor or owner. Non-excusable delays are caused by the contractors own action and/or inaction. These can be caused by the fault of the contractor, or his subcontractors, material, workforce or suppliers. The delay damages from the contractor is regarded could be retrieved by the owner conceivably. Lieshmann (1991) presented the consequences of delays in construction, especially from the legal point of view. Herbsman et al. (1995) catalogued the influence of delays on time, cost and quality. Baldwin Manthei (1971) studied the causes of delay in building projects in the USA. The major causes of delay were the result of weather, labour supply and subcontractors. These authors found that adequate planning at the very early stages of the project is important for minimizing delay and cost overruns in most projects in developing countries. This study dealt with developing countries where workers are relatively skilled. The authors realised that some of these problems relate to the special characteristics of this part of the world, such as productivity, whereas others are inherent in the nature of construction projects, such as planning and control problems. Yates (1993) developed a decision support system for construction delay analysis called the delay analysis system (DAS). The main categories of delays in the DAS system include engineering, equipment, external delays, labour, management, materials, owner, subcontractor and weather. Assaf et al. (1995) studied the causes of delay in large building construction projects in Saudi Arabia. Some of the mos t important causes of delay included approval of shop drawings, delays in contractors payment by owners, design changes by owners, cash problems during construction, the relationships between different subcontractors schedules in the execution of the project, the slowness of the owners decision-making process, design errors, excessive bureaucracy in project-owner organization, labour shortages and inadequate labour skills. From analysing the factors causing the delay of project, there should be elicitation on whether it can be diminished by application of process management. Atkin, BorgbrantJosephson (2003) argues that ideas of what should be considered in the design stage of a new building often seems to be a headache for architects, engineers and clients. These ideas invariably lead to some compromise between the demands of hard engineering and softer issues, with the potential likewise to compromise on the physical characteristics and performance of the building leading to some measure of failure. Examples of failure include high energy costs, health problems and structural destruction because of moisture, for which the occupant must pay directly or indirectly. Long-term socio-economic consequences can occur from this as well. Current problems are failures resulting from neglect of building physics principles are examined and their causes are highlighted. Research is continuing into the development of tools to help reduce the risk of failure and to highlight the costs and risks attached to the insufficient attention to building physics principles. Theories on Manufacturing Process and Process Management According to Melan’s(1992) research, a well- managed manufacturing process has the following characteristics: 1. Clearly defined ownership. Traditionally, ownership of a manufacturing operation is generally clear and explicit; it resides with a manager. The manager responsible for the operation is readily identifiable. The organization objectives, its output, and what the manager is accountable for must be fully understood. Standards such as cost, schedule, and quality are established for judging the manager’s performance. However, in recent years, authorized work teams and self-directed work groups where employees are assuming some of the tradition roles of management have gradually take the place of the traditional management ownership. A process owner, whether an individual or a team, is fully responsible for yield, cost, quality, and schedule, and must management the process to the targets set on these standards. Further, an owner has the authority to change or oversee a change in the process within his or her area of jurisdiction. 2. Defined boundaries. Manufacturing processes have a clearly defined beginning and end. He final output, or deliverable, as well as the input required to create it are clear and unambiguous. What is sometimes not clear, however, is whether output specifications truly reflect customer requirements and whether input specifications represent what is needed in the ensuring transformations. The lack of understanding of requirements on either the input side or output side underlies many business processes. In a well-managed manufacturing process, requirements problems are minimized through conscious effort aimed at specifying the work product as it proceeds from one operation to another. 3. Documented flow of work. Work flow in a manufacturing process is generally documented in great detail. There are several reasons for this. Documentation provides a permanent record of the manner in which a physical transformation takes place for production purposes. This record also provides a reference point or baseline from which any changes are to be made and serves as a means for replicating the process. Finally, documentation also serves as both a training and reference aid for the personnel involved in the process. 4. Established control points. Control points serve as a means for regulating the quality of work. Because of the natural variation that occurs in physical process, control points are established to manage variation. These points involve such activities as inspection, verification of required characteristics, and the disposition of discrepant material. 5. Established measurements. Measurements provide a statistical basis for controlling the flow of work and managing variation. Statistical techniques such as the control chart serve as useful tools for managing variation in many operations of a repetitive nature. 6. Control of process deviations. In managed processed, corrective action is performed in a timely manner and from a statistical basis when an undesirable variation occurs. Feedback and regulation are the heart of process control and, without control, the process loses its capacity of providing consistent output quality. Anderson’s (1994) theory clearly introduces the manufacturing process. He states that the most obvious characteristics of a production facility are the volume of items produced and the variety of different products made using the same resources. The volume and variety characteristics provide one way to look at the process of manufacture. Usually an increasing volume of production, in term of the number of individual units of each product, will go hand in hand with decreasing variety, in terms of the number of different products. And the author classifies the manufacturing process into three types: Mass Production involves producing a small number of different products in a great quantity, which provides the stereotype of manufacturing industry: long assembly lines where men or machines endlessly turn on the same product month after month. One characteristic of a mass production process is that operations are linked together in a line: when one operation is finished on a produc t it moves directly to the next operation; Batch Production is used when there are a greater variety of products being produced, with correspondingly smaller volumes. In this situation it is usual to have machinery and equipment which can be used to carry out operations on a number of different products. A single machine will carry out an operation on a whole batch of items of one kind and then be set up to carry out a similar operation on a whole batch of items of another kind; One-off production is used when individual customers each require an individual product, which is different from any product the company has made in the recent past. This implies low volumes but the greatest possible variety. With very large and complicated items the manufacturing process may be project based. This indicates that the manufacturing processes sufficiently complex, and over a long enough time-scale, that the major difficulties are associated with planning how various different operations and ac tivities will fit together. Born (1994) has provided a systematic method for integrating process management with quality management. It is based on a notion called the Quality Process Language (QPL), which is capable of representing and analysing all process within an organization. It also provides a basis for quality management approaches, such as ownership of processes, improved communication and compliance with requirements and regulations. QPL has been used in many types of organisation, large and small, highly structured and loosely structured. It provides a foundation for practical approaches such as facilitated workshops, process mapping and improvement, and documentation of procedures. The author also point out that activities and roles inputs and results of any organization can be well represented if the nation of QPL is mastered and then this notion can be converted into ordinary text and flow charts, for use in procedure and other documentation about the organization. The use of QPL as author states provides a common language for process and quality specialists to communicate directly. This offers an opportunity to discuss and design organizational and process changes without ignoring the effect on quality. QPL is a diagrammatic language, and it makes it easier for non-quality specialists to understand how processes affect quality and vice versa. Process Management in Construction Report (Kagioglou, Cooper, AouadSexton, 2000) introduces the findings and recommendation on the process management relate to the state of the construction industry at the present time and recommend some solutions as t in respect of how some of the problems might be overcome by transferring established practices from the manufacturing industry. However, the authors deem that it must be very careful when transferring knowledge and practices from manufacturing into the construction industry due to a number of reasons. First, the differences between the level of maturity of both processes and practices are distinct, with manufacturing having the lead. Second, because construction depends heavily on Temporary Multi-organizations (TMOs) while long-term partnership arrangements normally play the operation role in the manufacturing industry, the structure of the industries and of the organization of project personnel is dissimilar. Finally, comparison between the processes and the practices of both industries must be made by considering the levels in which they exist, such as strategic, managerial and operational. Therefore, clarification of process levels can have an important influence on the management of those processes. Kagioglou (1998) argues that there are two chief perspectives of manufacturing that construction can benefit from: the project process or New Product Development (NPD) and the operational and production processes. The first relates very closely, both in terms of nature and content, to the design and construction process. For itself, the development that of a solution from a demand identified in the market place or internally within an organization to the implementation is considered. This is achieved by organizing the activities that need to take place in a number of phases, which are made distinct by the determination of review points between the phases. This is very similar to the enactment of a construction project, the difference being that the distinction between the phases is usually determined by the entry of the different parties or functions, for example, architects, contractors, to the process. The second area is related to the way in which the production of a product, incl uding material flow, process design and resources planning, is undertaken. Indeed, a number of very effective philosophies and practices such as Just in Time (JIT), lean production and others have a legacy of optimized production in the manufacturing sector. JIT aims to improve production by utilizing the internal and external supply chains in terms of people and material flow. The first two benefits can be realized in the construction industry perhaps more readily than the third one, which requires a significant reorganization and mind-shift of the litigation-driven industry. This investigation concentrates on what can be absorbed from the NPD project process of manufacturing, and reference to it is made throughout the description of the Generic Design and Construction Process Protocol (GDCPP). Koskela (1992) expresses in his report that currently some construction subproducts are produced in processes that possess a manufacturing character. The assembly of such components with the building frame usually represents a minor share of the total costs. Windows, doors, elevators, prefabricated concrete components, and prefabricated houses, are examples of this kind of manufactured product. In regard to quality management, clear progress has been made in many countries. Many supplying firms have acquired quality certification according to the ISO standard. The application of the new production philosophy is least problematic in this part of the construction industry: the methods and techniques developed in manufacturing can be applied directly. However, except for quality management techniques, only a minor fraction of the factories and plants delivering to construction sites have begun to implement the new philosophy. It may be anticipated that this transformation will proceed r apidly after having gained initial momentum. Thus, industrialized construction might gain competitive benefits sooner than site construction. Additionally, Koskela (1992) summarized the condition of Implementation of process improvement by engineering and construction organizations. The inherent recommendation of the new philosophy to construction practitioners is clear that the share of non value-adding activities in all processes has to be systematically and persistently decreased. Increasing the efficiency of value-adding activities has to be continued in parallel. Construction should adopt the new production philosophy. In manufacturing, the new production philosophy improves competitiveness by identifying and eliminating waste (non value-adding) activities. Traditionally, construction is viewed and modelled only as a series of conversion (value-adding) activities. For example, waste activities such as waiting, storing inventory, moving material, and inspection are not generally modelled by Critical Path Models (CPM) or other control tools. Construction has traditionally tried to improve competitiveness by making conve rsions incrementally more efficient. But judging from the manufacturing experience, construction could realize dramatic improvements simply by identifying and eliminating non conversion (non value-adding) activities. In other words, actual construction should be viewed as flow processes (consisting of both waste and conversion activities), not just conversion processes. As demonstrated previously by the manufacturing industrys experience, adoption of the new production philosophy will be a fundamental paradigm shift for the construction industry. The implications of this for design are that the process of construction must be developed in conjunction with the design itself. An initial set of design and improvement principles for flow processes are presented that can serve as an implementation guideline. Major development efforts in construction, like industrialization, computer integrated construction and construction automation has to be redefined to acknowledge the need to balance flow improvement and conversion improvement. The conceptual foundation of construction management and engineering, being based on the concept of conversion only, is obsolete. Formalization of the scientific foundations of construction management and engineering should be a primary long term task fo

In that sense, the documentary synthesizes a great amount of historical, social and cultural information about the twentieth century. It can be used to prompt extensive discussions, to stimulate students to undertake special research projects, to write papers or combine the arts and/or cultural knowledge into a learning experience. Since the documentary is ninety minutes in length, planning and scheduling viewing time for students is essential so that the documentary can be viewed in either one or two class periods. Teachers are encouraged to view and discuss the documentary together and decide whether it is more efficient to use it in teaching one discipline or if students might profit more from discussions that are not discipline bound. The Teacher's Guide is designed for those teachers who want to use RICHARD WRIGHT: BLACK BOY to enhance the experiences of their students as they explore many and various school subjects. The guide is not designed to be exhaustive. It provides ideas for student activities and assignments, bibliographies of Wright's work, and a selected listing of background sources. Some older materials are included to suggest the state of scholarship and thinking about issues within Wright's lifetime or as reminders of what works might have influenced his thinking. In making assignments, it is suggested that the teacher add current articles and books that are deemed appropriate. The pre-viewing questions and activities are designed to help students gain background knowledge. The post-viewing student assignments focus on ways Wright's works mentioned in the documentary can be used to promote broader inquiries among the disciplines. Because the documentary contains scenes that portray Negro lynchings and an African woman's bare breasts, it is recommended that teachers and administrators below the college level review the program before showing it to students. Questions and activities are provided in the following disciplines: History, Education, Psychology, Literature, Sociology, and Political Science/Cultural Studies. The bibliography completes the guide.

Mutations in KCNQ1 Ion Channel May Cause Jervell and Lange-Nielsen Synd

Mutations in KCNQ1 Ion Channel May Cause Jervell and Lange-Nielsen Syndrome Abstract Jervell and Lange-Nielsen Syndrome is a human disorder that causes deafness and an irregular heartbeat. It is caused by a mutation in a protein that is a potassium ion channel. The mutations lead to a protein that does not serve the purpose it was designed to serve. It is difficult to treat, but there are things that can be done for both the cardiac and auditory aspects of it. Implantation of a device used as a sort of bionic ear can be used as treatment for the deafness characteristic of JLNS. The cardiac portion of JLNS can be treated by either a preventative step or with an implantable device used to stop arrhythmias (irregular beating of the heart) once they have started. Jervell and Lange-Nielsen syndrome is a recessive genetic disorder caused most commonly by mutations in the gene that codes for the KCNQ1 protein. In JLNS, these mutations cause a premature termination of the protein synthesis, leading to a loss of function. It is also known that KCNQ1 can mutate to cause a gain of function (e.g. a quickened heartbeat). Another disorder known as Romano-Ward syndrome involves changing a few of the amino acids within the protein so that the protein retains its basic shape and function, but is a lot less efficient. Without mutations, the KCNQ1 protein is a potassium ion channel, meaning that it transfers potassium ions between a cell and its surroundings. When mutated, KCNQ1 can cause deafness, and long QT syndrome (a disorder in which the heart takes longer to recharge than normal (QT segment is longer than average), often leading to fainting or sudden death.)

The involvement of the International Brigades in the Spanish Civil War :: European Europe History

The involvement of the International Brigades in the Spanish Civil War On the 18 July 1936, leading Generals of the Spanish Army led a revolt against the democratically elected Popular Front government of Spain. Within days the country was plunged into civil war with the Republicans fighting the insurgent Nationalists for control of the country. The various democracies of the world turned their backs on Spain's plight and even hindered the Republicans by supporting non-intervention in the conflict. However, many people came to help the Republic. Las Brigades Internacionales, the International Brigades, would eventually include almost 40,000 men and women from 53 different countries, from all around the world. The International Brigades began as an idea in July and August of 1936, but soon its formation became the main work of the Comintern (the body with the responsibility of fostering the world-wide spread of Communism). Each Communist party was instructed to raise volunteers who would be sent to Spain by train or boat. Around 60% of the volunteers were Communists, but non-Communists were also welcomed. The first group of recruits came to Spain by train from Paris, and arrived at their base in Albacete, halfway between Madrid and Valencia, on the 14th of October. It was there that the 500 French, German and Polish recruits began training. The theme of the recruitment propaganda was based on the slogan that Spain should be "The grave of European Fascism", and with this in mind volunteers continued to flow into Spain from France. One of the organisers of recruits in Paris was the future Marshal Tito - Joseph Broz. In Albacete the volunteers were organised into language groups and the base was put under the command of Andre Marty. The Brigades were to be led by General Emilio Kleber and intensive training was to take place in the base before going to the front. The International Brigades baptism of fire came on the 8th of November 1936, when the XIth and XIIth Brigades went to the Madrid front. They numbered about 3,500 men altogether, and were extremely important to the defence of Madrid. The fighting in Madrid eventually reached stalemate and the Brigades were transferred to other fronts. The XI, XIII and XV Brigades fought at the Brunete offensive of July 1937, where losses were very high, and where Oliver Law, the Afro- American commander of the Lincoln Battalion was killed. The Brigades also played a major part in the Aragon offensive of August 1937, and were formally incorporated into the Republican Army around this time.

Jack Sparrow Ca

Jack Sparrow Character Analysis. The Pirates of the Caribbean film series is one of the most popular film series to run its course through theaters in recent years. Action, adventure, and romance are some of the things we come to expect when we sit down to watch these amazing film adventures. But one of the things we can rely on most is the presence of Captain Jack Sparrow. While Sparrow was conceived to be only a supporting character, he proved to be popular after he was added into Disney’s theme park ride that spawned the movie series.Of course, a character as â€Å"far out† as Captain Jack had to be played by someone equally out-there: Johnny Depp. First we’ll talk about how Depp got into the role of Captain Jack and then I will analyze how Jack is portrayed as a character. In 2001, Depp was at Walt Disney Studios looking to do a family film. However, the fact that the Pirates theme park ride was going to be adapted into a film caught his attention first.Depp looked at the movie adaptation as a chance to revive his favorite movie genre,  and he was even more pleased when he found out the script fit his personality perfectly: a quirky pirate looking for adventure and in the end, showing he has a soft side. Depp was cast on June 10, 2002. Producer  of the series Jerry Bruckheimer  said that Depp was â€Å"an edgy actor who will kind of counter the Disney  Country Bears  soft quality and tell an audience that an adult and teenager can go see this and have a good time with it. When the cast got together for their read-through of the script, Depp surprised everyone by portraying the character in an off-kilter manner. After Depp did some research of his own on 18th century pirates, he compared the swashbucklers to modern rock stars and said he would base his performance on  Keith Richards. In a comic follow-up, Richards would later appear in two cameos as Jack's father,  Captain Teague, in  At World's End  and  On Stranger Tides. Director Gore Verbinski and Jerry Bruckheimer had confidence in Depp, in part because Orlando Bloom would be playing the traditional â€Å"hero† character in the series.Depp also improvised the film's final line, â€Å"Now, bring me that horizon†, which was writer Ted Elliot’s favorite line. Disney executives were, at first, confused by Depp's performance. Some even asked him whether the character was  drunk  or gay. Michael Eisner  even proclaimed while watching the events unfold, â€Å"He's ruining the film! †Ã‚  Depp actually fought back and responded, â€Å"Look, these are the choices I made. You know my work. So either trust me or give me the boot.   Some industry insiders also questioned Depp's casting, as he wasn’t known for working in a traditional studio setting and had even been called an unconventional actor. Depp's portrayal as Captain Jack Sparrow was critically acclaimed. Alan Morrison said â€Å"Gloriously over-the- top  Ã¢â‚¬ ¦ In terms of physical precision and verbal delivery, it's a master-class in comedy acting. †Ã‚  Roger Ebert  also found his performance â€Å"original in its every atom. There has never been a pirate, or for that matter a human being, like this in any other movie  Ã¢â‚¬ ¦ his behavior shows a lifetime of rehearsal. Ebert also praised Depp for moving away from the how Captain Jack was written. Depp won a  Screen Actor's Guild  award for his performance, and was also nominated for a  Golden Globe  and an  Academy Award for Best Actor, the first in his career. Film School Rejects  argued and wrote, â€Å"That because of Pirates, Depp has become as much a movie star as a  character actor. Johnny Depp returned as Jack Sparrow in  Dead Man's Chest, the first time the actor ever made a sequel. Drew McWeeny  stated, â€Å"Remember how cool  Han Solo  was in  Star Wars  the first time you saw it?And then remember how much cooler he seemed when  Empire  came out? This is that big a jump. †Ã‚  Depp received an  MTV Movie Award  and a  Teen Choice Award  for  Dead Man's Chest, and was also nominated for an  Empire Award  and another  Golden Globe. For his performance in  At World's End, Depp won an  MTV Movie Award  for Best Comedic Performance, as well as a  People's Choice Award, a  Kids' Choice Award, and another  Teen Choice Award. He has signed on to reprise the role for future sequels. Captain Jack appeals to us as moviegoers because he brings out our inner-most sense of adventure.We want him to succeed and we feel like we are right there when he takes us on an adventure. The first time we meet Captain Jack in The Curse of the Black Pearl he is sailing into Port Royal on a dinghy-like boat that is sinking to the ocean floor the during the whole scene. He eventually walks onto the dock from the crow’s nest, acting if nothing ever happened. He immediately pays off a dock worker in order to skip the mandatory ID check required to enter the city. This is what we love from a character; someone who makes the best of his situation and finds a way to get into the crowd.In the real world, we would never considering acting like Jack does. But in the movies, his adventure-seeking nature is something we crave. Despite all of the moral faults of Sparrow, the audience still finds him loveable. This is all thanks to Johnny Depp’s masterful portrayal. Depp was able to create a very human, multifaceted, believable character. What’s even weirder is that Jack is not the typical pirate that peaks our interests. He is not bulky, muscular, or very intimidating. His actions at some times are very effeminate.Although he used his brain more than brawn, the films will show us that he is very athletic on his own. Sparrow also shows us that it doesn’t matter who our friends are. Just look at his crew while he is commanding the Black Pearl. It is the most rag-tag group of pirates you will ever see. It even included a woman in the first movie, something that was very taboo for Captains to have in their crew at the time. Another bright spot on Sparrow is that he uses everything that is available to him. He may not be the best swordsman, but if there is anything that could possibly be a weapon near him, he will use it.Anything you can think of really; whiskey barrels, horses, even him fighting on a water-wheel that generates power. In Dead Man’s Chest Jack was found to be the accepted leader of a tribe of Caribbean natives. He somehow mastered their language and was living in the lap of luxury until he found out that he was going to be a human sacrifice. Things like this are what draw us to The Captain. His wild and crazy adventures may come to an end someday, but he will always be memorable to me and definitely left a mark on the movie world.

Psychiatric Side Effects Hormonal Contraceptives Health And Social Care Essay

Current scientific literature widely supports the fact that estrogen and Lipo-Lutin have some effects on the cardinal nervous system, but adult females have ever understood that they feel otherwise depending on what portion of their hormonal rhythm they are on. Womans are rather familiar with the psychological and emotional hurt caused by premenstrual syndrome. Family members can place with the noticeable behavioural alteration from pre to post-puberty females due to the addition of sex endocrines within the organic structure. It so follows that the inquiry of what, besides the primary effects of sex endocrines, estrogen and Lipo-Lutin are making in the organic structure to arouse such behavior-altering phenomena? To adult females, it is clear that endocrine degrees are changing the manner we think and feel, yet many hormonal preventives fail to name important temper and behavioural alterations as a side consequence. In fact, one article by Douma et Al. ( 2005 ) states that despite p resenting alterations in absolute and comparative degrees of estrogen and Lipo-Lutin, emotional and sexual side effects of unwritten preventives are mostly ignored in the research literature. If these endocrines do in fact map as behavioural and psychological qualifiers, are at that place unsought effects of consuming hormonal preventives that can greatly change temper and behaviour? This is an effort to reply, through a reappraisal of the literature on the interactions between endocrines and temper upsets, if the side effects associated with hormonal preventives are excessively great of a hazard to female outlook to be taken.Female Generative Cycle:After making sexual adulthood, a adult female will travel through the generative rhythm until making climacteric, the point at which she will no longer be able to hold kids. Womans have monthly two generative rhythms that are tightly linked by hormonal ordinance. During adult females ‘s rhythms, the organic structure prepares for f ertilisation of the egg, which is released about halfway through the rhythm. If the egg is non fertilized after being released, menses occurs and the rhythm repeats itself. Ultimately, control of the generative rhythm belongs to the encephalon. The ovarian rhythm includes all of the alterations that happen in the ovaries while a adult female remains fertile. First, gonadotrophin let go ofing endocrine ( GnRH ) is dispensed from the hypothalamus through the intermediate hypophyseal portal system, exciting the anterior pituitary to release both follicle exciting endocrine ( FSH ) and luteinizing endocrine ( LH ) into the blood stream. When the endocrines reach the sex glands, they bind to receptors on the ovaries and originate a concatenation of events that begin follicular growing, a procedure that will bring forth an egg as the female gamete. As the follicle grows within the ovary, it begins to let go of estradiol at low degrees, which maps in the uterine rhythm and besides inhibits the release of more FSH and LH from the pituitary. As the follicle nears ripening, estradiol degrees rise steeply. The high concentration of estradiol plants opposite how low estradiol concentrations in the organic structure map, exciting the hy pothalamus to release GnRH and doing a rush in both FSH and LH. The rush in LH allows the follicle to make adulthood, and ovulation by and large occurs about a twenty-four hours subsequently. The follicular tissue remains in the ovary and is transformed into a impermanent secretory organ known as the principal luteum in response to LH. The principal luteum secretes the endocrines estradiol and Lipo-Lutin, which exhibit negative feedback on the encephalon to diminish FSH and LH degrees. As these degrees get really low, the principal luteum disintegrates, the negative feedback rhythm is disrupted, and the rhythm starts over once more ( Cambell et al. , 2008. ) The uterine rhythm begins with the thickener of the liner of the womb in readying for the possible nidation of an embryo. This occurs in response to estradiol being secreted from follicles within the ovary. After ovulation, Lipo-Lutin and estradiol work in concurrence to turn endometrial secretory organs in the womb and increase blood supply to the endometrium while go oning to increase the thickness of the uterine liner. If an egg is non fertilized before it passes out of the female, the principal luteum will devolve. The bead in ovarian endocrines causes the blood vass of the endometrium to compress and starves the uterine liner, ensuing in menstruations ( Cambell et al. , 2008. )Hormonal Contraceptives:Pregnancy is a long-run committedness that is energetically expensive to the female and requires life manner alterations to care for the offspring until they are able to care for themselves. For these and other personal grounds, ways to forestall gestation have been developed to let a twosome to make up one's mind when they are ready to hold a kid. Of class, abstention and male barrier methods are available, but to guarantee a greater grade of protection in intercourse the female may take to utilize hormonal preventives to change the organic structure ‘s rhythmic rhythms that prepare for gestation. Effective and reversible, many adult females today choose a hormonal birth control for greater independency in life. How frequently the hormonal preventive demands to be taken depends on the method of pick and type of endocrine. There is a battalion of different types of hormonal contraceptive method available that a female can take from to forestall gestation which involves legion methods of bringing and types of endocrine. Common manners of bringing include an ingestible tablet signifier, a skin spot placed at assorted locations on the organic structure, a ring placed inside of the vagina, and hormonal injections given in the clinic. The endocrines these pre ventives contain are most normally the endocrines produced by the ovary. Hormonal preventives map in a assortment of different ways to forestall gestation. To understand how they work, it is of import to understand how ovarian endocrines map in the organic structure of course. In general, most steroid endocrines are transcription regulators. Steroid endocrines are produced by changing the substrate cholesterin and act on a broad assortment of tissues. As antecedently discussed, the ovaries produce two endocrines rhythmically, estradiol and Lipo-Lutin. Hormonal preventives consist of progestogen, a man-made, progesterone-like endocrine that can be given entirely or in concurrence with man-made estrogen. Hormonal contraceptive method contains man-made derived functions of estrogen and Lipo-Lutin in combination or by themselves. Most unwritten preventives work by forestalling contraceptive method, but some alter the endometrium to forestall nidation of the embryo. Combined preventives work through negative feedback to the hypothalamus, stamp downing GnRH and therefore FSH and LH secernments. Without the rush of LH/FSH degrees, the follicle will non finish development, impeding the production and release of a secondary oocyte. Other contraceptive method methods known as consecutive readyings prescribe estrogens for some period of clip and so Lipo-Lutin, following the normal rhythmic sequence of the organic structure ‘s rhythm. Progesterone is besides given entirely and exhibits negative feedback on the release of LH, which can change the organic structure to the point where it acts as if it is pregnant, impeding the release of any other eggs ( Hadley, M. , Levine, J. , 2006. ) Progesterone is synthesized as a precursor to both of the other sex endocrines, androgens and estrogens, in the thecal cells that form the follicle. However, merely little sums of Lipo-Lutin are produced in this manner – most of the Lipo-Lutin in the organic structure is manufactured by granulosa cells of the principal luteum. In several stairss, cholesterin is oxidized to pregnenolone, which is once more oxidised and undergoes keto/enol tautomerization to organize Lipo-Lutin. Progesterone is the endocrine responsible for fixing the organic structure for gestation and keeping the embryo one time a adult female becomes pregnant by exciting growing and development of the womb and Fallopian tubes. Progesterone exhibits control on the secernment of GnRH and gonadotropin secernment ( Hadley, M. , Levine, J. , 2006. ) Estradiol is produced in the ovaries in response to follicular growing following the release of the pituitary endocrines LH and FSH. The complete synthesis of estradiol occurs within the follicle of the ovary. First, a multistep mechanism converts cholesterin, which is obtained from the consumption of fatty acids, to the intermediate androgen androstenedione. Some androstenedione is converted to testosterone, which is enzymatically oxidized by aromatase for the transition to active sex endocrine estradiol. When estrogen starts being produced at high degrees in the female following pubescence, it is responsible for the ripening of the female sex variety meats, including the vagina, ovaries, womb, and Fallopian tubes. In these countries it causes tissue growing and development, increased blood flow, mucus secernment, prostaglandin synthesis, and increases the figure of Pitocin and estrogen receptors in the womb. Besides the sex variety meats, estrogens have an consequence on many other countries of the organic structure. Estrogen has several actions on the pituitary, including the followers: positive and negative feedback set uping the secernment of the FSH and LH ; increases the figure of GnRH receptors ; increases the production of Pitocin ; and increases the production of lactogenic hormone. To all of this, estrogen besides affects the cardinal nervous system, and it is possibly these effects that are most unreassuring when sing hormonal birth control. Behaviorally, the addition of sexual desires and maternal inherent aptitude alters libido ( Hadley, M. , Levine, J. , 2006. )Side Effectss of Hormonal Contraceptives:Physical, mental, and societal wellbeing are of import facets of a healthy life. Treatments are beset for physical manifestations of unwellness, but when it comes to psychiatric upsets solutions are much less abound. Many of these unwellnesss have a familial constituent in add-on to environmental factors, doing chances for successful intervention lo w due to the individualised nature of psychiatric upsets as a whole. Investigating possible causes for mental unwellness should however be a precedence for doctors. A consolidative feature of work forces and adult females that may be a promising path to some conditions impacting mental wellness prevarications in the sex endocrines, the biological indexs of birthrate and maturity. However, a big figure of psychiatric upsets affect adult females to a greater extent than work forces – while adult females are fertile, they produce estrogen and Lipo-Lutin in greater sums than their male opposite numbers. It is therefore possible that these steroid endocrines are lending to the addition of temper upsets in females. Hormones diffuse straight into the endothelial cells of the blood encephalon barrier and hold several well-documented maps on the hypothalamus and pituitary. In add-on to these countries, receptors for the sex steroids are found in other locations where emotion, knowledg e, and behaviour is regulated ( Westberg, L. , Eriksson, E. , 2007. ) The effects of decreased degrees of endocrines has been studied in conditions such as premenstrual dysphoric upset, perimenopausal dysphoria, postpartum depression, postpartum psychosis, dysphoria induced by unwritten preventives or hormonal replacing therapy and anabolic steroid-induced aggression ; correlativities may be between sex steroids and autism, depression, panic upsets, anxiousness upset, agoraphobia, transsexualism, dependence, and attention-deficit hyperactivity upset ( Westberg, L. , Eriksson, E. , 2007. ) The reappraisal paper by Westberg and Eriksson ( 2007 ) analyzed cistron polymorphisms of the sex steroids and their relation to psychiatric status, but clearly stated is the deduction that if cistron discrepancies are associated with a certain status, so it is likely that they influence the homeostasis of that peculiar variable. In surveies of the female life span, fluxes of estrogen can be linked to many behavioural upsets: while a female is fertile, estrogen degrees flux greatly during the luteal stage of the catamenial rhythm – this corresponds to premenstrual syndrome, which is experienced in most adult females undergoing menstruations ; after holding a kid, estrogen degrees bead, which could take to postpartum depression ; come ining climacteric, irregular rhythms cause big fluctuations in estrogen degrees, and many adult females cite experiencing depressed during this clip ; and eventually, during climacteric, estrogen degrees bead to extreme depressions from what the organic structure is used to, and diminution in many psychological provinces is exhibited ( Douma, S. , et Al. 2005. ) In add-on to its engagement in memory, concentration, and cognitive map, estrogen mediates several neurotransmitters in the encephalon that may play a function in temper – for illustration, the effects on se rotonergic map and Dopastat degrees may indicate towards a nexus with depression ( Douma, S. , et Al. 2005. ) A pilot survey on the relation of depression to hormonal preventives indicated that users of unwritten preventives may be more inclined to depression than non-users ( Kulkarni, et Al. 2005. ) In a double-blind survey by Grounds et al. , ( 1970 ) depression as a side consequence of hormonal preventives was found to be independent of antecedently bing symptoms. The survey concluded that depression was due to the hormonal chemicals in the preventives. Figure 1: Degree of Mood Change in Oral Contraceptive Users Compared to Placebo Several theories exist on the mechanisms for how the sex endocrines can be changing temper. Plausible explainations include an estrogen-induced vitamin B6 lack and subsequent lessening in 5-hydroxytryptamine and GABA degrees due to the low affinity of the decarboxylases for pyridoxal phosphate ; a Lipo-Lutin and estrogen mediated augmentation of GABA-induced suppression and suppression of glutamate excitement ; and a progesterone-mediated addition in monoamine oxidase activity ensuing in reduced concentrations of 5-hydroxytryptamine ( Oinonen, K. , Mazmanian, D. , 2001. ) Estradiol may impact Dopastat receptors, increase the release of Dopastat in the subcortical part of the prosencephalon, and diminish the consumption of Dopastat, all of which would increasing the length and badness of the consequence ( Vulink, et al. , 2006. ) Research suggests that this portion of the encephalon, the karyon accumbens, may work in pleasance, dependence, being happy or sad, and many other emotions ( Vulink, et al. , 2006. ) Harmonizing to an article by Parry and Rush ( 1979 ) , temper alterations, in peculiar depression, have been found to be correlated to the length of unwritten contraceptive method usage, the concentration of Lipo-Lutin, and a familial sensitivity to the disease. Although it may hold some kind of environmental constituent, surveies have demonstrated that depression may develop due to lessenings in the degree of monoamine neurotransmitters found in the encephalon, notably 5-hydroxytryptamine and noradrenaline. Hormonal contraceptive method may be making this instability by impacting the production and debasement of 5-hydroxytryptamine and noradrenaline. Serotonin is created in a mechanism of several stairss that hydroxylizes and so decarboxylates the amino acid tryptophan. Oral preventives may heighten tryptophan metamorphosis and act as a competitory inhibitor of vitamin B6 phosphate, both of which decrease the handiness of tryptophan for the production of 5-hydroxytryptamine. Other s urveies confirm that tryptophan may be metabolized at an increased rate in users of unwritten preventives ( Shaarawy, et al.,1982. ) Noradrenaline is synthesized through a series of stairss that convert tyrosine to L-dopa and Dopastat, which is oxidized to make the terminal merchandise. Pyridoxal phosphate is used to catalyse the reaction of L-dopa to dopamine, a procedure which is inhibited through the usage of hormonal preventives. Besides, preventives may diminish plasma tyrosine degrees, take downing the handiness of the precursor to norepinephrine, and increase monoamine oxidase, an enzyme that destroys noradrenaline after it is created. Changes that occur to the encephalon under the influence of steroid endocrines can be observed through the usage of EEGs. The correspondence of electrical activity with altering endocrine degrees is clear indicant that Lipo-Lutin and estrogen map in the encephalon ( Becker, et al. , 1982. ) Estrogen receptors have been found in the hypothalamus, though there is still much to be elucidated on the location and distribution of Lipo-Lutin receptors ( Becker, et Al. 1982. ) Women taken hormonal preventives have been observed to hold a decreased alpha beat on such surveies ( Parry, Rush, 1979. ) These consequences may assist find how psychological abnormalcies develop after consuming steroid endocrines. Hormonal preventives have been implicated in impacting the badness of obsessive-compulsive upset. In a survey by Vulink, et Al. ( 2006 ) it was found that unwritten preventives could overstate or better the symptoms associated with this mental unwellness. The survey goes on to propose that ground for this alteration might hold to make with the consequence of endocrines on the map of Dopastat in the encephalon. Since OCD might besides be affected by Dopastat, this is cause for concern. Datas on temper alterations can be hard to quantify, doing the undertaking of placing a questionable nexus between hormonal preventives and mental upsets complex. In add-on, variables between persons can do the state of affairs even more upsetting. For illustration, it is possible that a sensitivity to mental unwellness contributes to negative temper alteration experienced with hormonal preventives. Some preliminary work on this many-sided undertaking suggests that the correlativity between negative temper alterations and hormonal preventives may be affected by the temporal form of dose more than their components and ratio ( Oinonen, K. , Mazmanian, D. , 2001, ) yet others province that the relationship may be more luxuriant, and likely justly so ( Douma, S. , Al. 2005. ) To clear up the input of familial versus drug-induced psychiatric upsets, we can look to information from a twin survey. Kendler, et Al. ( 1988 ) performed a survey on 1131 twins to place which side effects of unwri tten preventives may be related to genetic sciences and which effects are related to consumption of the drug. Consequences from this survey supported a familial influence over the psychiatric side consequence of depression if it is related to the physical side effects of weight addition and hydrops, which were clearly influenced by familial factors. The consequences besides suggested that familial factors may hold an of import function in crossness. However, a multivariate analysis in the same survey suggests that these psychiatric symptoms were independent of both the physical side effects of unwritten preventives and symptoms of built-in psychiatric upsets. The survey concluded that although cistrons have been definitively demonstrated to act upon depression, psychiatric symptoms and a antecedently bing sensitivity to mental unwellness appear to be comparatively independent. Another decision of this survey stated that the environment did non look to hold an consequence on psychiat ric symptoms reported by the users of unwritten preventives. Although the survey has some mistakes to be taken into consideration, such as self-reporting symptoms by topics and merely detecting twins whom volunteered, this grounds suggests that hormonal contraceptive method may hold a direct function in bring oning assorted psychiatric upsets as a side consequence of forestalling gestation.Decision:Most medicative drugs have some kind of side consequence that is by and large unpleasant but deserving taking for the curative consequence it was prescribed for. Birth control is more of an optional medicine than many prescription drugs, but is still taken by many adult females in America and around the universe. It can be hard to restrict a medical specialty to a individual curative consequence when the chemical occurs of course in our organic structures and affects many facets of homeostasis, though when side effects change from being inconvenient or somewhat straitening to something th at can impact mundane behaviour and temper, concern for what is being put into our organic structures becomes elevated. Even with the possibility of temper alterations, hormonal preventives still provide an effectual agencies of birth control that may outweigh the assorted side effects. However, drug companies and doctors need to accurately province the likeliness of the side effects so that adult females and their households can do an informed determination when make up one's minding to utilize this signifier of birth control – besides, this can increase the chance that adult females will go on to take the pills on a regular basis and run into their terminal ends ( Freeman, Shulman, 2008. )
