Principles Of Recovery Oriented Approach †MyAssignmenthelp.com

Question: Discuss about the Principles Of Recovery Oriented Approach. Answer: Key Principles Of Recovery Oriented Approach The recovery oriented strategies offer a transformative conceptual frame-work for practice, culture and service delivery in the mental health service provision (Aneshensel, 2013). The recovery oriented approach recognizes the value of lived experience and get it along with the expertise knowledge and the skills of the peer support workers, who have lived experience, and use this experience to assist other individuals (Bland, Renouf and Tullgren, 2015). There are various recovery oriented approach principles which the social worker uses to deliver best practices of treatment to the mental individuals (Corrigan, Druss and Perlick, 2014). These are uniqueness of the individuals, the real choices, attitudes and the rights, dignity and the respect, partnerships and the communication. Additionally, there is also the principle of evaluating recovery (Turner, 2017). How Social Work Assessment Can Be Conducted Within Recovery Oriented Approach The assessment is important part of helping process and it start from the moment one begins to engage in the working relationship (Corrigan, Druss and Perlick, 2014) When it comes to the assessment of the social work it is important to follow various guideline such as focusing on the child--client, planning and developing on a clear analysis (Aneshensel, 2013). These aspects are important since they demonstrate one is taking a systematic approach when it comes to assessment through use of conceptual model using recovery oriented approach and be able to deliver a comprehensive analysis (Daniels and Amour, 2014). It is important to understand that a good assessment is one that highlights the three domains. The interaction of these domains entails a careful investigation during the assessment (Aneshensel, 2013). Key Issues From The Case Study In this case study, it is about April a 21 year of age girl who has recently graduated. The past experience of April has not been good. First, she was bullied by the other students in her childhood because of being of mixed race. This caused her to have a low self-esteem as she felt less unattractive and fat. During her entire time in school she has in no way invited friends over to their residence as she felt embarrassed by her mixed racial heritage. Putting this aside she managed to outshine the other students and she was chosen as the student representative, this was the happiest period of her life. When it came to relationship with the boys she had extreme anxiety especially when it came to handling their sexual advances. She was involved in two relationships one with Graham but after end of high school they broke up. The second relationship was with Josh who she had been dating but she does not feel devoted to the relationship. April is not devoted to her job nor motivated to work and socialise with other people. She has been feeling agitated and she lost interest in doing anything like clearing her apartment nor her personal appearance. She is avoiding everybody particularly Josh, her parents and even her brothers. She is even lost interest in furthering her education. One of the is sue she lack self-esteem (Flanagan, Farina and Davidson, 2016). It is very evident since childhood she has been bullied and she felt unattractive and fat. This can be linked to the life domain of self-identity problem domain. This problem is more rooted to the identity of person in other people who are associate with her. Identity is regarded as what one knows but rather how you know it (Daniels and Amour, 2014). In the case of April, hers is associated with the low self-esteem she feel not worth anything. This aspect in most of the time occurs when a person believes they have no worth, and cannot achieve anything (Rogers and Pilgrim, 2014). This happens when other people in your life, in this case Aprils classmates bullied her. She felt she is not worthy anything. When addressing this issue it is important to ask yourself these questions do you like yourself? And are you good at anything that is useful? (Payne, 2015). On her issue that has been observed is that she has given up in life and lacks motivation. It is seen that she does not care about her job, nor motivation to continue with her studies as previously she had projected. Fur ther, it is observed she has lost all interest such as she does not clean her apartment and pays less attention to her personal appearance. This individual seems to have lost all hope in life and wants to give up. This could be aligned on the principle of real choices and the attitudes and the rights. When looking at the real choices important to support and empower April to enable her to make her own choices about how she intend to lead her live and acknowledge the choices she made to become meaningful and creatively explore. The life domain is based on aspect of education. As observed from the case study April studied hard in school and got into a career but later on she realized she might be better off working in a different one, and this would require a different education. In her case she previously wanted to pursue a post graduate, but because of the lack of motivation she felt that returning to school as an adult responsibility would be seen as a daunting task on her end considering she currently has a job. Another issue which needs to be addressed is the state of depression she is having. Based on the case study it is evidence that April has a depression, this can be clearly being seen from the way she wants to be alone and she is avoiding the people who loves her such as her boyfriend, parents and even her brother. Any individual who separate themselves from the other may feel lonely or even experience some depression. However, this is dependent on individuals as some do not experience the same. I n the case of April she seems depressed because of the following observation; one aspect on why she may be feeling depressed is that she has been feeling on edge when getting ready for work or even for drama group. She uses all sort of excuses to avoid going with others. She is much anxious when the social functions have been sprung on her without prior notice. Another aspect is that she has lost a lot of weight. Moreover, April has lost all the interest in cleaning her apartment as well as personal appearance. Based on the shortcoming which have happened to her in past experiences; she feels less attractive, fat and sees herself hated by other people. This leads to low self-esteem, and negativity thoughts striking in and she ends up in depression (Healy, 2014). When individuals belittle one they tend to develop feelings that they are not worth something or perhaps they cannot achieve anything. This could be in regards to the physical aspects, or race. In the context of the case study, it is evident that April is avoiding her family members, and Josh, the reason is because she does not want them to see what she has become. They highly regarded her as a focused individual, who has a great job and wanted to achieve more in life. Currently, it seems this has changed greatly, she does not want her current job, does not want to pursue further studies, lost her weight tremendously and she does not appear presentable as she used to be. This issue can be associated to the domain of social problems especially on the part of the family and friendships (Bryman, 2015). Individuals are the social creatures who need the comfort and support of healthy relationships. It is easy for some individuals to accomplish, but other individuals find it perilously difficult task. This is because, some individuals have specific difficulties when it comes to forming a particular kinds of a relationship. They may have a good relationships, but may be uncomfortable in a dating or even a romantic setting. In the case of April she had a difficult family life while she was growing up, which resulted to having no prospect for satisfying adult relationship even though she has a boyfriend. She had a difficult time all around her family life, had few friends and no prospect to satisfy adult relationships which she had with the men. Evidently based on the case study she seems lonely, particularly, when she does not want to go to social functions, does not want to be associated with others including her family members and Josh her boyfriend. Moreover, it is also evident she does not want to meet others from the fact that she feels anxious when social functions are sprung to her without notice (Bland, Renouf and Tullgren, 2015). Aboriginality has also placed a significant part towards the development of April life. She was more buried by the other children because of her race and her physical status since she was also fat. This issue greatly affected her self-esteem and she grew wanting to prove to others she was as better as they are. She did through education and outshone the other students and was even elected the student representative. Social Work Theories As a social worker it is important to understand various theories which would be important to help individuals who have a given habit or even exhibit behaviour and assist them (Healy, 2014). Feminist perspective theory views the social world in way which illuminated on the forces which create as well as support inequality, oppression and injustice and in doing so promotes to the pursuit of the equality and the justice (Bland, Renouf and Tullgren 2015). The theory focus on how the systems of power and oppression interact especially on the systematic racism, sexuality, as well as hierarchical class system. In this theory it would draw issues on why April has been behaving socially with other individuals especially her family and friends. In her childhood she has been previously been confronted by the other children especially on her looks. This is a life crisis which occurred between her and the other children and it can greatly shape someones life by impacting their self-esteem downwards (Bland, Renouf and Tullgren, 2015). This theory would offer a centred approach for constituting a practice based service which is built on the research which would help the social worker in addressing diverse situations (Parker, 2017). The social worker could use the theory to relate and examine the condition which lead to the conflict which occurred to April childhood life and consequently help her to get over it as most of the time individuals tends not to forget when bad things happens (Parker, 2017). Cultural competences entails understanding and appropriately responding to the unique combination of the cultural variable which could include the beliefs, ethnicity as well as the gender identity. For the clinical approaches it would involve interviews style, assessment tools and therapeutic techniques which would be appropriate to address the issue affecting April. This is a social work practice which searches for the social barriers as well as structural inequalities in the activities which are conducted with the service worker. This theory will be useful to the social worker since it will offer a suitable, responsive as well as perceptive services which will react to the needs of April without considering their cultural variables (Bland, Renouf and Tullgren 2015). The theory will further help them to obtain knowledge and an understanding of their own selves, various groups and cultures to be able to effectively face the issues to a personal level and be able to help April to deal with her personal issues. Some of the issues she needs to address is how the society has oppressed her because of her race. She was often bullied as a child by the other student and this contributed negatively on her self-esteem and self-worth. Legal And Ethical Issues Social workers have always encountered legal as well as ethical choice in relation to their work with families, communities and organization. In the legal realm, the social workers should be cognizant for various set of the requirements and guidelines such as statutory law, common law and the regulatory law (Bland, Renouf and Tullgren, 2015). When it comes to the statutory law there are many federal laws which have been enacted by the legislatures and they affect the practices of social workers. Sometimes the social worker could encounter situation in which the legal standards could conflict to the professional ethical standards. In the case of the regulatory law they should be fully aware of the wide range of the federal state as well as the local regulations. One such is concerned to the protection of the confidential information. In the case of the April the social worker should keep what they are told confident even though it is related to the cases of alcohol or drug usage. This is based on the confidentiality Act of 1987. Further Information. On the further information as a social worker are important to help the client. Some of the things which I intend to discuss with the client before starting the sessions are as follows; one to contact the medical practioners (Rosenbaum, Tiedemann, Sherrington, Curtis and Ward, 2014). Based on this case of April I intend to involve other practioners to help me assist her such as nurse-midwife, as well as the clinical psychologist but before I can contact them it is important to discuss this with her so that she agrees and feel comfortable with them handling her case. Secondly, it is important to involve and liaise with her family member. In any mental health case as a social worker it is important to involve various parties such as family members to offer support to the patient to enable her recover quickly (Bryman, 2015). This is a fundamental aspect which I intend to discuss with her. References Aneshensel, C.S., 2013. Mental illness as a career: Sociological perspectives.

Social Security Tax System Social Security has been around for more than 60 years. It has been an important part of American life. It was created in 1935 shortly after the great depression. Social Security was created to be a protection for the American people against the hazards of unemployment, old age, and ill health. Today Social Security not only provides minimum protection for the retired worker, it also provides benefits for workers and their families due to death of a family wage earner or loss of income due to disability. Today there are about 150 million workers who are protected by social security, more than 44 million receive retirement, survivors and disability benefits form social security. American wage earners and their families are protected by social security and they pay taxes to help make the system work. There are two philosophies Social Security bases its payments on. First, the system is designed so that there is a link between how much a wage earner pays into the system and how much he or she will receive in benefits. For example, a high wage earner will receive more benefits while a low wage earner will receive less. Second, a base for economic security is provided by the Social Security system. Social Security provides a valuable package of retirement, disability and survivors insurance, which relieves families of financial burdens from supporting other family members. Social Security has made an enormous difference in the lives of older Americans. American workers can retire as early as age 62. At this age, wage earners are eligible to get reduced benefits from Social Security. Wage earners may wait for full retirement age to be eligible for full retirement benefits. Currently, full retirement age is 65, but will be moved up gradually starting in 2003. The new retirement age will be 67 for people born in 1960 or later. Social benefits payments are paid out to more than 9 in 10 retirees. In America, only 11 percent of senior citizens live in poverty. Without Social Security benefits, the percentage of seniors living in poverty would be much higher. Social Security is the major source of income for about two-thirds of elderly Americans, and for abut a third Social Security is virtually their only source of income. Retired Americans are given a dependable monthly income from Social Security. Automatic increases are tied to increases in the cost of living. Social Security gives retired American citizens a measure of deserved financial independence (and that measure is becoming lower every year). Social Security is more than a retirement program. It is also a protection plan for American citizens. Valuable disability and survivors' insurance protection are given to younger wage earners and their families. There are about 1 in 3 workers who are Social Security beneficiaries that are not retired. Monthly survivors' benefits are given to about 7.5 million people and more than 6 million workers and family members receive disability benefits. Social Security provides a foundation on which to build retirement security. Social Security, pensions and savings is a three-legged financial stool for a comfortable retirement. Unfortunately, there is only a little more than half of all workers whose employers have pension plans; and people are not saving for their future retirement. Pre-retirement earnings for the average worker are about 40 percent, provided by Social Security. Financial advisors say that the average worker will need 70 percent of pre- retirement earnings to live comfortably. Saving is an important part of retirement planning. Social Security will begin mailing statements to workers age 25 and older. The statement will show a worker's earnings history, as well as giving estimates of retirement, survivors and disability benefits. This statement will help with future financial planning. Demographics have been the main reason for Social Security's long-range financing problem. People, today, are living longer and healthier lives. In 1935,

Auguste Comte and His Role in the History of Sociology

Auguste Comte and His Role in the History of Sociology Auguste Comte was born on January 20, 1798  (according to the Revolutionary calendar then used in France), in Montpellier, France. He was a philosopher who is also considered to be the father of sociology, the study of the  development and function of human society, and of positivism, a means of using scientific evidence to discern causes for human behavior. Early Life and Education Auguste Comte was born in Montpellier, France. After attending the Lycà ©e Joffre and then the University of Montpellier, he  was admitted to the École Polytechnique in Paris. The École closed in 1816, at which time Comte took up permanent residence in Paris, earning a precarious living there by teaching mathematics and journalism. He read widely in philosophy and history and was especially interested in those thinkers who were beginning to discern and trace some order in the history of human society. System of Positive Philosophy Comte lived during one of the most turbulent periods in European history. As a philosopher, therefore, his aim was not only to understand human society but to prescribed a system by which we could make order out of the chaos, and thus change society for the better. He eventually developed what he called a system of positive philosophy, in which logic and mathematics, combined with sensory experience, could better assist in understanding human relationships and action, in the same way that the scientific method  had allowed an understanding of the natural world. In 1826, Comte began a series of lectures on his system of positive philosophy for a private audience, but he soon suffered a serious nervous breakdown. He was hospitalized and later recovered with the help of his wife, Caroline Massin, whom he married in 1824. He resumed teaching the course in January 1829, marking the beginning of the second period in Comtes life that lasted 13 years. During this time he published the six volumes of his Course on Positive Philosophy  between 1830 and 1842. From 1832 to 1842, Comte was a tutor and then an examiner at the revived École Polytechnique. After quarreling with the directors of the school, he lost his post. During the remainder of his life, he was supported by English admirers and French disciples. Additional Contributions to Sociology Though Comte did not originate the concept of sociology or its area of study, he is credited with coining the term and he greatly extended and elaborated the field. Comte divided sociology into two main fields, or branches: social statics, or the study of the forces that hold society together; and social dynamics, or the study of the causes of ​social change.   By using certain tenets of physics, chemistry, and biology, Comte extrapolated what he considered to be a few irrefutable facts about society, namely that since the growth of the human mind progresses in stages, so too must societies. He claimed the history of society could be divided into three different stages: theological, metaphysical, and positive, otherwise known as the Law of Three Stages. The theological stage reveals humankinds superstitious nature, one that ascribes supernatural causes to the workings of the world. The metaphysical stage is an interim stage in which humanity begins to shed its superstitious nature. The final and most evolved stage is reached when human beings finally realize that natural phenomena and world events can be explained through reason and science. Secular Religion Comte separated from his wife in 1842, and in 1845 he began a relationship with Clotilde de Vaux, whom he idolized. She served as the inspiration for his Religion of Humanity, a secular creed intended for the veneration not of God but of humankind, or what Comte called the New Supreme Being.  According to Tony Davies, who has written extensively on the history of humanism, Comtes new religion was a  complete system of belief and ritual, with liturgy and sacraments, priesthood and pontiff, all organized around the public veneration of Humanity. De Vaux died only a year into their affair, and after her death, Comte devoted himself to writing another major work, the four-volume System of Positive Polity, in which he completed his formulation of sociology. Major Publications The Course on Positive Philosophy (1830-1842)Discourse on the Positive Spirit (1844)A General View of Positivism (1848)Religion of Humanity (1856) Death Auguste Comte died in Paris on September 5, 1857, from stomach cancer. He is buried in the famous Pere Lachaise Cemetery, next to his mother and Clotilde de Vaux.

Guinn v. United States

Guinn v. United States Guinn v. United States was a United States Supreme Court case decided in 1915, dealing with the constitutionality of voter qualification provisions in state constitutions. Specifically, the court found residency-based â€Å"grandfather clause† exemptions to voter literacy tests- but not the tests themselves- to be unconstitutional. Literacy tests were used in several Southern states between the 1890s and 1960s as a way of preventing African Americans from voting. The unanimous decision in Guinn v. United States marked the first time the Supreme Court struck down a state law disenfranchising African Americans.   Fast Facts: Guinn v. United States Case Argued: Oct. 17, 1913Decision Issued: June 21, 1915Petitioners: Frank Guinn and J. J. Beal, Oklahoma election officialsRespondent: United StatesKey Questions: Did Oklahoma’s grandfather clause, in singling out black Americans as being required to take a voter literacy test, violate the U.S. Constitution? Did Oklahoma’s literacy test clause- without the grandfather clause- violate the U.S. Constitution?Majority Decision: Justices White, McKenna, Holmes, Day, Hughes, Van Devanter, Lamar, PitneyDissenting: None, but Justice McReynolds took no part in the consideration or decision of the case.Ruling: The Supreme Court ruled that residency-based â€Å"grandfather clause† exemptions to voter literacy tests- but not the tests themselves- were unconstitutional. Facts of the Case Shortly after it was admitted into the Union in 1907, the state of Oklahoma passed an amendment to its constitution requiring that citizens pass a literacy test before being allowed to vote. However, the state’s Voter Registration Act of 1910 contained a clause allowing voters whose grandfathers had either been eligible to vote before January 1, 1866, had been residents of â€Å"some foreign nation,† or had been soldiers, to vote without taking the test. Rarely affecting white voters, the clause disenfranchised many black voters because their grandfathers had been slaves before 1866 and were thus ineligible to vote.   As applied in most states, the literacy tests were highly subjective. Questions were confusingly worded and often had several possible correct answers. In addition, the tests were graded by white election officials who had been trained to discriminate against black voters. In one instance, for example, election officials rejected a black college graduate even though there was not â€Å"the slightest room for doubt as to whether† he was entitled to vote, concluded the U.S. Circuit Court. After the 1910 November midterm election, Oklahoma election officials Frank Guinn and J.J. Beal were charged in federal court with conspiring to fraudulently disenfranchise black voters, in violation of the Fifteenth Amendment. In 1911, Guinn and Beal were convicted and appealed to the Supreme Court. Constitutional Issues While the Civil Rights Act of 1866 had guaranteed U.S. citizenship without regard to race, color, or previous condition of slavery or involuntary servitude, it did not address the voting rights of former slaves. To bolster the Thirteenth and Fourteenth Amendments of the Reconstruction-era, the Fifteenth Amendment, ratified on February 3, 1870, prohibited the federal government and the states from denying any citizen the right to vote based on their race, color, or previous condition of servitude. The Supreme Court faced two related Constitutional questions. First, did Oklahoma’s grandfather clause, in singling out black Americans as being required to take the literacy test, violate the U.S. Constitution? Second, did Oklahoma’s literacy test clause- without the grandfather clause- violate the U.S. Constitution? The Arguments The state of Oklahoma argued that the 1907 amendment to its state constitution was validly passed and clearly within the powers of the states granted by the Tenth Amendment. The Tenth Amendment reserves all powers not specifically granted to the U.S. government in Article I, Section 8 of the Constitution to the states or to the people. Attorneys for the U.S. government chose to argue only against the constitutionality of the â€Å"grandfather clause† itself while conceding that literacy tests, if written and administered to be racially neutral, were acceptable. Majority Opinion In its unanimous opinion, delivered by Chief Justice C.J. White on June 21, 1915, the Supreme Court ruled that Oklahoma’s grandfather clause- having been written in a way to serve â€Å"no rational purpose† other than to deny African American citizens the right to vote- violated the Fifteenth Amendment to the U.S. Constitution. The convictions of Oklahoma election officials Frank Guinn and J.J. Beal were thus upheld. However, since the government had previously conceded the point, Justice White wrote that, â€Å"No time need be spent on the question of the validity of the literacy test, considered alone, since, as we have seen, its establishment was but the exercise by the State of a lawful power vested in it not subject to our supervision, and, indeed, its validity is admitted.† Dissenting Opinion As the court’s decision was unanimous, with only Justice James Clark McReynolds not taking part in the case, no dissenting opinion was issued. The Impact In overturning Oklahoma’s grandfather clause, but upholding its right to require pre-voting literacy tests, the Supreme Court confirmed the historic rights of the states to establish voter qualifications as long as they did not otherwise violate the U.S. Constitution. While it was a symbolic legal victory for African American voting rights, the Guinn ruling fell far short of immediately enfranchising black Southern citizens. At the time it was issued, the court’s ruling also nullified similar voter qualification provisions in the constitutions of Alabama, Georgia, Louisiana, North Carolina, and Virginia. While they could no longer apply grandfather clauses, their state legislatures enacted poll taxes and other means of restricting black voter registration. Even after the Twenty-Fourth Amendment prohibited the use of poll taxes in federal elections, five states continued to impose them in state elections. Not until 1966 did the U.S. Supreme Court declare poll taxes in state elections unconstitutional.   In final analysis, Guinn vs. United States decided in 1915, was a small, but a significant first legal step in the Civil Rights Movement toward racial equality in the United States. It was not until passage of the Voting Rights Act of 1965 that all remaining legal barriers denying black Americans the right to vote under the Fifteenth Amendment- enacted nearly a century earlier- were finally outlawed.

Speech Made in the Conference, Concerning Japan's Aggression Essay

Speech Made in the Conference, Concerning Japan's Aggression - Essay Example Japan is such a country that can best be described as aggressive, with its acts being tantamount to belligerence, especially towards China. Some of the acts of aggression that Japan has carried out may be illustrated forthwith. It is open knowledge that Japan on September 18th, 1931 sent its army and some of its political leaders to invade Manchuria, which is the eastern seaboard of China. The worst part of this problem is not merely personified in Japan’s acts of aggression, but on Japan’s lack of goodwill to being accountable for its actions. For instance, in 1933, after the Manchuria crises ended, Japan’s delegate walked out of the League of Nations when the findings by the Lytton Commission were being read out and mooted. In so doing, Japan was not only excising itself from the rest of the international community, but also parading unwillingness to take responsibility. Arrogance was also the driving force behind Japan’s walk out since Japan had already pacified Manchuria from China and singlehandedly made Manchuria a puppet state, Manchukuo. Japan even had the audacity to make Emperor Pu Yi as the head of Manchukuo who was a stooge in every respect. Similarly, Japan’s aforementioned willingness to take responsibility is underscored by the fact that the tabling of the Lytton Commission’s findings was supposed to be accompanied with discussions on China’s appeal for an interstate approach towards Japan’s aggression (Christensen, 75). Japan’s bellicose stance was further shown in it engaging the Chinese army near Peking, at the Marco Polo Bridge in 1938, following the ‘China Accident.’ It is important to note that Japan’s problem is one which is heavily embedded in wrongful thinking and attitude. For a fact, ever since Japan won the Sino-Japanese War which took place between 1894 and 1895, Japan has become increasingly stubborn throughout the orient, after it knew that it had a stranglehold in the Asian continent. China’s compelled recognition of the Korean independence and its forced concessions on Liaotung Peninsula and Taiwan were to serve as Japan’s reassurance and propitiation. Unfortunately, Japan grew into a bully. It is important to note that with much power comes, responsibility in lieu of belligerence. Japan, other developed and developing countries ought to realize this. It is important that Japan appreciates the fact that when it joined the Allies in World War I, it gained a lot when the League of Nations granted it, the Asian colonial territories that had been being controlled by Germany in the 1919 Treaty of Versailles. That these territories were rich, is a matter that is underscored by the inclusion of the Shantung Peninsula and Micronesian islands which had been under the tutelage and ownership of China and Germany, respectively. Thus, the citing of Japan’s landlocked status as a reason behind its unbridled antagonism cannot wash. How the U.S. Plans To Handle the Situation There are several measures that America has considered as tenable solution to the problem of Japan’s aggression. The measures are both short and long term. One of the long term approaches to the problem is the reevaluation of economic policies with Japan. It is well known that since 1920s, Japan got less interested in western model of economic liberalism. This is because, while reeling from the

Women and Economics during Colonial America and Before and After Essay - 1

Women and Economics during Colonial America and Before and After American Revolution - Essay Example That writing reflects the struggles, anguishes and the tragedies within her family, local scandals and her viewpoint of the politics. The story raises question about the scenario of the colonial America. That makes us interested to examine the social and economic role of the women in colonial America, and the change in pattern of the society and the emerging role of female in social and economic perspective1. (Ulrich, 1991) In the colonial period of America, especially the mid and late 17th century the women of America used to lead monotonous lives full of work and duties. The women from the poorer families had to take less workload than the women belonging to the wealthier families2. The matter of fact is that the society used to evaluate the work of a woman according to their contribution to their own family3. (Courtney, and Ranger, 1999; Eldridge, 1997, p.62) As the British had colonized America the American society followed the social customs and rituals of the British society. The males of the families had to perform the out home duties such as earning, farming etc. On the other hand their female counterpart had to engage themselves in household chores such as cooking, child breeding, childcare, home decorating, housekeeping etc. The hardworking wives were granted the rank of goodwives. Those who performed the activities such as caring domestic animals and vegetable gardens, producing unique delic ious foods, stitching clothes, producing candles, soaps for home consumption etc could get the mark of excellence from their husbands and relatives as good women4. (Wightman Fox, Richard and Robert B. Westbrook, 1002, p.125; DuBois, and Dumenil, 2005, p. 77) The women used to form the networks of female friends and the relatives (obviously female) regarding the household duties. Through the network formation they used to make some exchanges

Critical Analysis of Quantitative Research Essay Example for Free

Critical Analysis of Quantitative Research Essay The researchers in this experiment aimed to â€Å"Investigate the quantitative differentiation of pulmonary dendritic cells in smoker with or without chronic obstructive pulmonary disorder (COPD) to explore the possible role of dendritic cells in smokers suffering COPD† (Yan-wei, Yong-jiang, Xian-sheng, 2010). Dendritic cells (DCs) are inflammatory cells that are considered to be the promoter of immune responses; knowing this the researchers hypothesized that DCs may play an important role in the development of the disease. See more: how to write an analysis Subjects were broken into three groups based on an illness gradient: (control group, smokers without airflow obstruction, and COPD group as determined by the Chinese Society of Respiratory Disease). Samples of alveolar tissue were taken from these three groups and studied using immunohistochemical staining and immunofluorescence confocal laser scanning. The results from the experiment are portrayed using a one-way analysis of variance, Pearson’s r coefficient, graphs, and scatter plots. The conclusion of the data showed that â€Å"The quantity of the DCs significantly increased in smokers with COPD compared with non-smokers or smokers without COPD† (Yan-wei et al., 2010). A critical analysis of this article received a 31.5. The article was well put together and provided many up to date references as resources to give a better understanding of the research. The authors explained their methodologies in great detail and the production of their data was concise and easy to read. However, the study lacked when it came to representing a diverse population. The study also lacks in terms of providing evidence of the consent of the subjects and the evidence of the governing body of the experiment. The research that was done in this experiment allowed scientist to develop new hypotheses concerning dendritic cells and their role in chronic diseases such as COPD. The links that were made with this research between dendritic cells, lung capacity, and cigarette smoke could potentially be the forefront of new treatments and earlier diagnoses for COPD victims.

Temptation and Survival in Sir Gawain and the Green Knight Essay exampl

Temptation and Survival in Sir Gawain and the Green Knight In Sir Gawain and the Green Knight, Gawain faces choices as part of the Green Knight's game. The game is not the simple exchange of axe blows as it appears to be. It is actually a game of temptation and rule-breaking. In the end, Gawain fails this test given by the Green Knight and King Arthur's half-sister. When the Green Knight arrogantly rode into King Arthur's domain, he showed no respect for the celebrated knights. He rudely laughed away the praise he had heard of King Arthur as "the praise of you, prince, is puffed up so high" (Norton Anthology 1465). He also ridiculed the knights as they hesitated to accept his challenge. Gawain eventually accepted the challenge, but didn't fully understand what the test would actually be. In what was probably a rage of protecting King Arthur's honor, Sir Gawain chopped off the Green Knight's head and began the game. King Arthur's soldier didn't understand that this would be a game of rule following instead of a match determining warrior skills. The Green Knight is a charac...

Creation of a pop video or short film lasting approximately 5 minutes

Our brief this year was to create a pop video or short film lasting approximately 5 minutes. The AS brief was to create billboards or posters about health. They differ in that one concentrates on moving image where the other concentrates on print. However they both require strong visual images that provoke thought. New skills I have developed in creating a pop video are, how to create a storyboard and shooting scripts as well as how to use the cameras and editing equipment more efficiently. (Our treatment describes our A2 brief in more detail.) I decided I wanted to create a music video, as audio is 50% of the media experience, so teamed up with others who also wanted to make a music video. We then decided on which song we wished to create the video for. We did this by brainstorming ideas (in our creative journals) and then choosing a song that we all liked and the creative ideas we wished to include in the video (type of shots, characters etc). At first we were producing a video for Jackson Five ‘I want you back' but this proved to be harder than we originally thought and in addition it had already been created. So this is when we decided to change the genre of music from Pop to Indie and chose to create a video for Feeder's ‘Yesterday went too soon.' This song has never had a video created for it and therefore our audience would not have any prior expectations of what the video should look like and include. The only major issue we had with creating a pop video for this song is that we could not conform to all conventions of a music video; in this case we could not include the band Feeder, as we do not have access to them. We looked at various indie videos before we began to storyboard. This was done to get ideas for our own video and to make sure it fitted in with the genre. There are two things that I believe influenced our film to a great extent, one is a video by Cold Play that uses reversing within the video like we do and the other is not a music video but a film, Sliding Doors. The element we took from this video was what if one minor event did/or didn't happen how would the story turn out? This creates interest as the audience is left wondering for a while what is going to happen next? What will change? (why might these ‘themes' be more appropriate for an indie music video?) To organize ourselves, the time we had and the equipment we needed to use; we each decided on roles depending on what our strengths and weaknesses were. Jess was Director, James was Producer, Beth was Camerawoman and I was Location Researcher and Editor. However because we worked as a team these roles were not as defined and we helped each other with the tasks we found difficult. To organize our selves and get the best out of the time we had with the equipment we planned each day thoroughly. We created shooting scripts, storyboards and treatments (all of which are in our appendix) to enable us to get each shot correct virtually first time as in industry we would not have unlimited, free access to the props, actors and equipment. We learnt about scripting, shooting schedules and treatments by looking at other peoples work for inspiration and to see what worked for them. We then adapted what we found out to suit us and created our own video. To create the storyboard we took the best ideas from everyone and the most influential ideas from music videos. (you could say a bit more about specific music videos that you used for inspiration, and also on how you defined the generic conventions of indie music video in particular) The storyboard was created while we listened to the song so that we could match the visuals to the sound. I believe our treatment and storyboard are good as we can understand them and if we were to give them to another group to create I believe they would be able to produce the pop video, as we want it. We developed them by first deciding on the major points we wanted to include and then showing them to our teacher and changing and adapting them accordingly. Section Two – Analysis of finished product Music videos are primarily used to promote the song of a band. (although they can be a bit like adverts, indie music videos in particular are also often trying to reinforce a particular image of the band) The benefit with a music video over say live performance is that it can reach parts of the world that the band may not be able to. Music videos can generally be split into three categories; Narrative videos (ones which tell a story), Performance clip (ones that focus on band performance) and (non)Narrative video (ones that concentrate on the rhythms and moods of the song). We chose to concentrate on a narrative based video as it fits with the genre we had decided upon. (Why?) The genre of our music video is Indie. It was important when making our music video that we best matched the editing of our film with our chosen song. This is to make the video easy and comfortable to watch and to create a professional finish. Typical conventions of this style of music video include a storyline and maybe some band members featuring within the video. (you need to say more about this, and how these elements help to develop an image of the band) We conformed to as many conventions as we could without making the video looking artificial or amateur. We especially conformed to the convention of editing being faster with shorter shots than normal. We did this to keep up with the pace of song and to keep the viewer from getting bored. To make sure that the video flowed smoothly we used straight cuts most of the time with dissolves and fades where we felt appropriate. (Why?) Indie music does not have the bright upbeat cheer as a pop video does but it is not dark and sinister either so to convey realism we used natural light so that the video doesn't look like an over dramatic piece of work. Music videos are often playful, experimental and usually about stretching the boundaries of ‘realist(ic)' style. In a way we have done this by using the rewinding shots and the slowing down of the falling orange juice glass. The narrative of our video is about a guy who has a regular, mundane routine of waking up, getting dressed and going to catch his bus, we look at what would happen should this vicious circle break and as it turns out his life become better because of it (He meets up with the love of his life). This is parallel to the music as the song is of similar content where its lyrics can be interpreted in many ways. For this video to work we needed to capture the audience's attention to do this we used another convention of music video which is the visual hook. This is where a close up of the band is used to keep the audience's attention. In our case we used the extreme close up of the guy's eyes right at the beginning of the video. It goes on longer than a normal video clip would to establish the fact that he had just woken up and so essentially throws the audience right into the video. (Do we see him again? How does this develop image?) A variety of styles ranging from realism to symbolism have been used within our film, for example when the glass breaks. This is a key moment in the video as the glass breaking symbolises the vicious circle of daily routine breaking. This dramatic event is emphasized by the image being slowed down making the audience notice the importance of it. Another example of symbolism is the routine as a whole being shown then re-wound back to be re-shown again, this emphasises the unexciting, everyday life that the guy leads. The ideology of our video is that something so small can change the route in life you take forever; i.e. because of the glass breaking he has met up with his old girlfriend and is now happy. (It is fairly conventional heterosexually romantic – how does this relate to target audience, and the image you are trying to create of the band? How do you want male and female audiences to feel about them? You can cover that in the next section) Section three – Institutions and Audiences Our music video has been created for the mainstream audience and therefore hopefully appeals to most people, however we understand that not everybody likes the indie style of music and therefore will not appeal to all. Our target audience is for young teenagers, but as our song is a ballad we could expect some older listeners. We have tried to aim the video at all genders as the music industry is now strongly supported by both. We have also aimed the video at all social classes but predominantly middle – working class people (that's quite a diverse range†¦.) as they make up the larger proportion of our population. We have enforced this by not using any obvious branded clothing or objects. We tried to aim the video at all races but did not have access to them to use within our video, so instead tried to produce a video that would not offend anybody. (anyway indie music has a predominately white audience) I believe an independent record company or the band itself would fund the making of this video, as that is how it is generally done in industry. Music videos are created to promote a song and to create awareness of the artist so the best place for them to be seen would be on 24hr music channels like MTV or on music shows like Top of the Pops or CD:UK, by putting the video on these sorts of programs people who are interested in music will purposefully watch them and tell friends about the songs and so forth so that by the time the single comes out everyone knows about them and the band should get good record sales. Our music video reflects generic conventions through the use of narrative and visual hooks. From the movie sliding doors we have taken the theme of something so little can change your life forever and we have shown how it can go either way. We have also taken influence from Cold Play's recent music video; from this we used the use of rewinding to keep the audience interested. (why is Coldplay a good reference point?) To find out if our video had achieved its aims we asked a focus group to watch the video and then answer some questions on it to see how they would respond to the text. When asked about the genre of this piece the entire group got that it was an indie music video. Therefore fulfilling that part of the requirements. We then asked about more complicated issues like the Ideology of our video. Ours being based on the theory that can something so small change your life forever and if it can is there such a thing called fate? Again everybody understood this with a main answer being ‘How little things can change the fate of a day, love as well,' and ‘how easily it can be changed.' To see if our video fitted in with conventions of music videos in general and in particular indie music videos we asked our focus group about them. A major point that came up was the fact music videos usually include the band, which in our case was not possible because we did not have access to them. However on a brighter note our mise-en-scene and lighting was suitable and appropriate for the video and created the realism need to fit in with the conventions of the genre. A key point to making a good pop video is the length of shot and how well the video has been edited. So to see if we had taken these points into enough consideration we asked the focus group about them to see if they matched our own views on various elements in the video. For example the length of the rewinding shots, most people found it got tiring after watching it twice through and so felt that the rewinding shots could have stop at where the orange juice was being poured. Also they felt that they liked the repetitive effect, but it could have been a bit faster, as not to drag on. We next wanted to see if people could see where our influences had come from. Although no one in the focus group figured it out they came up with their own they we felt were just as appropriate. Some of them include the film; Run Lola Run and Craig David's single 7 Days. Another point we could not agree on as a group was whether or not to have more shots of the girl in the video to establish her character and the focus group it seems had mixed views as well. Some said there should be more of her to enable the viewer to understand the narrative more yet others said that the video worked well just concentrating on the one character, so that issue is left unresolved. In addition to the above problem our group could not decided whether to leave the sound effects (that appeared by accident) or to cut them out so we decided to leave them in and see what our audience thought of them. Most thought that they should have been left out because they didn't really fit in and I am inclined to agree. (Also they take away the focus from the music) To finish off the feedback session we asked for people's general opinions on our video. For example whether they liked it or not and why they did or did not like it. Most found the idea interesting and original with a play on the essentially simple narrative.

Pirate Ships - History and Culture

Pirate Ships - History and Culture During the so-called Golden Age of piracy (roughly 1700-1725), thousands of pirates terrorized shipping lanes all over the world, particularly in the Atlantic and Indian Oceans. These ruthless men (and women) needed good ships to be able to run down their prey and escape from pirate hunters and navy vessels. Where did they get their ships, and what made for a good pirate craft? What Was a Pirate Ship? In one sense, there was no such thing as a â€Å"pirate† ship. There was no shipyard where pirates could go and commission and pay for a pirate ship to their specifications. A pirate ship is defined as any vessel whose sailors and crew are engaged in piracy. Thus, anything from a raft or canoe to a massive frigate or man of war could be considered a pirate vessel. Pirates could and did use very small boats, even canoes  when nothing else was at hand. Where Did Pirates Get Their Ships? Since no one was making ships exclusively for piracy, pirates had to somehow capture existing ships. Some pirates were crewmen on board naval or merchant vessels who took over by mutiny: George Lowther and Henry Avery were two well-known pirate captains who did so. Most pirates simply traded ships when they captured one that was more seaworthy than the one they had been using. Sometimes brave pirates could steal ships: Calico Jack Rackham was cornered by Spanish gunships one night when he and his men rowed over to a sloop the Spanish had captured. In the morning, he sailed away in the sloop while the Spanish warships shot up his old ship, still anchored in the harbor. What Would Pirates Do With a New Ship? When pirates got a new ship, by stealing one or by swapping their existing ship out for a better one belonging to their victims, they usually made some changes. They would mount as many cannons on the new ship as they could without significantly slowing her down. Six cannons or so was the minimum that pirates liked to have on board. The pirates usually changed the rigging or ship’s structure so that the ship would sail faster. Cargo spaces were converted into living or sleeping quarters, as pirate ships usually had more men (and less cargo) onboard than merchants vessels. What Did Pirates Look for in a Ship? A good pirate ship needed three things: it needed to be seaworthy, fast, and well-armed. Seaworthy ships were especially necessary for the Caribbean, where devastating hurricanes are a yearly occurrence. Since the best ports and harbors were usually off-limits to pirates, they often had to ride out storms at sea. Speed was very important: if they could not run down their prey, they would never capture anything. It was also necessary to outrun pirate hunters and navy ships. They needed to be well-armed in order to win fights. Blackbeard, Sam Bellamy, and Black Bart Roberts had massive gunboats and were very successful. Smaller sloops had advantages as well, however. They were quick and could enter shallow inlets to hide from searchers and evade pursuit. It was also necessary to careen ships from time to time. This is when the ships were intentionally beached so that the pirates could clean the hulls. This was easy to do with smaller ships but a real chore with larger ones. Famous Pirate Ships Model Of Queen Anns Revenge Blackbeard The Pirates Flagship On Display At The Maritime Research. John Pineda  /Getty Images 1. Blackbeards Queen Annes Revenge In November of 1717, Blackbeard captured La Concorde, a massive French slaving ship. He renamed her Queen Annes Revenge and refitted her, mounting 40 cannons on board. The Queen Annes Revenge was one of the most powerful ships around at the time and could go toe-to-toe with any British warship. The ship ran aground (some say Blackbeard did it intentionally) in 1718 and sank. Researchers believe they have found it in the waters off of North Carolina. Some items, such as an anchor, bell, and spoon have been found and are displayed in museums. Captain Bartholomew Roberts, engraving. Culture Club/Getty Images 2.  Bartholomew Roberts Royal Fortune Most of Roberts flagships were named Royal Fortune, so sometimes the historical record gets a little confusing. The largest was a former French man of war that the pirate had refitted with 40 cannons and manned by 157 men. Roberts was aboard this ship during his fateful final battle in February of 1722 3.  Sam Bellamys Whydah The Whydah was a massive merchant ship captured by Bellamy on her maiden voyage in 1717. The pirate modified her, mounting 26 cannons on board. She was shipwrecked off of Cape Cod not long after she was taken, however, so Bellamy did not do much damage with his new ship. The wreck has been found, and researchers have found some very interesting items which have allowed them to learn more about pirate history and culture. Sources Cawthorne, Nigel.

Blood pressure Essay Example for Free (#2)

Blood pressure Essay Blood pressure (BP), sometimes referred to as arterial blood pressure, is the pressureexerted by circulating blood upon the walls of blood vessels, and is one of the principal vital signs. When used without further specification, â€Å"blood pressure† usually refers to thearterial pressure of the systemic circulation. During each heartbeat, blood pressure varies between a maximum (systolic) and a minimum (diastolic) pressure.[1] The blood pressure in the circulation is principally due to the pumping action of the heart.[2] Differences in mean blood pressure are responsible for blood flow from one location to another in the circulation. The rate of mean blood flow depends on the resistance to flow presented by the blood vessels. Mean blood pressure decreases as the circulating blood moves away from the heart through arteries and capillaries due to viscous losses of energy. Mean blood pressure drops over the whole circulation, although most of the fall occurs along the small arteries and arterioles.[3] Gravity affects blood pressure via hydrostatic forces (e.g., during standing) and valves in veins, breathing, and pumping from contraction of skeletal muscles also influence blood pressure in veins.[2] The measurement blood pressure without further specification usually refers to the systemic arterial pressure measured at a person’s upper arm and is a measure of the pressure in the brachial artery, major artery in the upper arm. A person’s blood pressure is usually expressed in terms of the systolic pressure over diastolic pressure and is measured in millimetres of mercury (mmHg), for example 120/80. The table on the right shows the classification of blood pressure adopted by the American Heart Association for adults who are 18 years and older.[4] It assumes the values are a result of averaging blood pressure readings measured at two or more visits to the doctor.[6][7] In the UK, blood pressures are usually categorised into three groups: low (90/60 or lower), high (140/90 or higher), and normal (values above 90/60 and below 130/80).[8][9] While average values for arterial pressure could be computed for any given population, there is often a large variation from person to person; arterial pressure also varies in individuals from moment to moment. Additionally, the average of any given population may have a questionable correlation with its general health; thus the relevance of such average values is equally questionable. However, in a study of 100 human subjects with no known history of hypertension, an average blood pressure of 112/64 mmHg was found,[10] which are currently classified as desirable or â€Å"normal† values. Normal values fluctuate through the 24-hour cycle, with highest readings in the afternoons and lowest readings at night.[11][12] Various factors, such as age and sex influence average values, influence a person’s average blood pressure and variations. In children, the normal ranges are lower than for adults and depend on height.[13] As adults age, systolic pressure tends to rise and diastolic tends to fall.[14] In the elderly, blood pressure tends to be above the normal adult range,[15] largely because of reduced flexibility of the arteries. Also, an individual’s blood pressure varies with exercise, emotional reactions, sleep, digestion and time of day. Differences between left and right arm blood pressure measurements tend to be random and average to nearly zero if enough measurements are taken. However, in a small percentage of cases there is a consistent difference greater than 10 mmHg which may need further investigation, e.g. for obstructive arterial disease.[16][17] The risk of cardiovascular disease increases progressively above 115/75 mmHg.[18] In the past, hypertension was only diagnosed if secondary signs of high arterial pressure were present, along with a prolonged high systolic pressure reading over several visits. Regarding hypotension, in practice blood pressure is considered too low only if noticeable symptoms are present.[5] Clinical trials demonstrate that people who maintain arterial pressures at the low end of these pressure ranges have much better long term cardiovascular health. The principal medical debate concerns the aggressiveness and relative value of methods used to lower pressures into this range for those who do not maintain such pressure on their own. Elevations, more commonly seen in older people, though often considered normal, are associated with increased morbidity and mortality. There are many physical factors that influence arterial pressure. Each of these may in turn be influenced by physiological factors, such as diet, exercise, disease, drugs or alcohol, stress, obesity, and so-forth.[20] †¢ Volume of fluid or blood volume, the amount of blood that is present in the body. The more blood present in the body, the higher the rate of blood return to the heart and the resulting cardiac output. There is some relationship between dietary salt intake and increased blood volume, potentially resulting in higher arterial pressure, though this varies with the individual and is highly dependent on autonomic nervous system response and the renin-angiotensin system.[21][22][23] †¢ Resistance. In the circulatory system, this is the resistance of the blood vessels. The higher the resistance, the higher the arterial pressure upstream from the resistance to blood flow. Resistance is related to vessel radius (the larger the radius, the lower the resistance), vessel length (the longer the vessel, the higher the resistance), blood viscosity, as well as the smoothness of the blood vessel walls. Smoothness is reduced by the build up of fatty deposits on the arterial walls. Substances called vasoconstrictors can reduce the size of blood vessels, thereby increasing blood pressure. Vasodilators (such as nitroglycerin) increase the size of blood vessels, thereby decreasing arterial pressure. Resistance, and its relation to volumetric flow rate (Q) and pressure difference between the two ends of a vessel are described by Poiseuille’s Law. †¢ Viscosity, or thickness of the fluid. If the blood gets thicker, the result is an increase in arterial pressure. Certain medical conditionscan change the viscosity of the blood. For instance, anemia (low red blood cell concentration), reduces viscosity, whereas increased red blood cell concentration increases viscosity. It had been thought that aspirin and related â€Å"blood thinner† drugs decreased the viscosity of blood, but instead studies found[24] that they act by reducing the tendency of the blood to clot. In practice, each individual’s autonomic nervous system responds to and regulates all these interacting factors so that, although the above issues are important, the actual arterial pressure response of a given individual varies widely because of both split-second and slow-moving responses of the nervous system and end organs. These responses are very effective in changing the variables and resulting blood pressure from moment to moment. Moreover, blood pressure is the result of cardiac output increased by peripheral resistance: blood pressure = cardiac output Xperipheral resistance. As a result, an abnormal change in blood pressure is often an indication of a problem affecting the heart’s output, the blood vessels’ resistance, or both. Thus, knowing the patient’s blood pressure is critical to assess any pathology related to output and resistance. The mean arterial pressure (MAP) is the average over a cardiac cycle and is determined by the cardiac output (CO), systemic vascular resistance (SVR), and central venous pressure (CVP),[25] Curve of the arterial pressure during one cardiac cycle The up and down fluctuation of the arterial pressure results from the pulsatile nature of thecardiac output, i.e. the heartbeat. The pulse pressure is determined by the interaction of thestroke volume of the heart, compliance (ability to expand) of the aorta, and the resistance to flow in the arterial tree. By expanding under pressure, the aorta absorbs some of the force of the blood surge from the heart during a heartbeat. In this way, the pulse pressure is reduced from what it would be if the aorta wasn’t compliant.[26] The loss of arterial compliance that occurs with aging explains the elevated pulse pressures found in elderly patients. The pulse pressure can be simply calculated from the difference of the measured systolic and diastolic pressures,[26] The arm–leg (blood pressure) gradient is the difference between the blood pressure measured in the arms and that measured in the legs. It is normally less than 10 mmHg,[27] but may be increased in e.g. coarctation of the aorta.[27] The larger arteries, including all large enough to see without magnification, are conduits with low vascular resistance (assuming no advanced atherosclerotic changes) with high flow rates that generate only small drops in pressure. The smaller arteries and arterioles have higher resistance, and confer the main drop in blood pressure along the circulatory system. Modern physiology developed the concept of the vascular pressure wave (VPW). This wave is created by the heart during the systoleand originates in the ascending aorta. Much faster than the stream of blood itself, it is then transported through the vessel walls to the peripheral arteries. There the pressure wave can be palpated as the peripheral pulse. As the wave is reflected at the peripheral veins, it runs back in a centripetal fashion. When the reflected wave meets the next outbound pressure wave, the pressure inside the vessel rises higher than the pressure in the aorta. This concept explains why the arterial pressure inside the peripheral arteries of the legs and arms is higher than the arterial pressure in the aorta,[28][29][30] and in turn for the higher pressures seen at the ankle compared to the arm with normal ankle brachial pressure index values. The endogenous regulation of arterial pressure is not completely understood, but the following mechanisms of regulating arterial pressure have been well-characterized: †¢ Baroreceptor reflex: Baroreceptors in the high pressure receptor zones detect changes in arterial pressure. These baroreceptors send signals ultimately to the medulla of the brain stem, specifically to the Rostral ventrolateral medulla (RVLM). The medulla, by way of the autonomic nervous system, adjusts the mean arterial pressure by altering both the force and speed of the heart’s contractions, as well as the total peripheral resistance. The most important arterial baroreceptors are located in the left and rightcarotid sinuses and in the aortic arch.[31] †¢ Renin-angiotensin system (RAS): This system is generally known for its long-term adjustment of arterial pressure. This system allows the kidney to compensate for loss in blood volume or drops in arterial pressure by activating an endogenous vasoconstrictorknown as angiotensin II. †¢ Aldosterone release: This steroid hormone is released from the adrenal cortex in response to angiotensin II or high serum potassiumlevels. Aldosterone stimulates sodium retention and potassium excretion by the kidneys. Since sodium is the main ion that determines the amount of fluid in the blood vessels by osmosis, aldosterone will increase fluid retention, and indirectly, arterial pressure. †¢ Baroreceptors in low pressure receptor zones (mainly in the venae cavae and the pulmonary veins, and in the atria) result in feedback by regulating the secretion of antidiuretic hormone (ADH/Vasopressin), renin and aldosterone. The resultant increase inblood volume results an increased cardiac output by the Frank–Starling law of the heart, in turn increasing arterial blood pressure. These different mechanisms are not necessarily independent of each other, as indicated by the link between the RAS and aldosterone release. Currently, the RAS is targeted pharmacologically by ACE inhibitors and angiotensin II receptor antagonists. The aldosterone system is directly targeted by spironolactone, an aldosterone antagonist. The fluid retention may be targeted by diuretics; the antihypertensive effect of diuretics is due to its effect on blood volume. Generally, the baroreceptor reflex is not targeted in hypertensionbecause if blocked, individuals may suffer from orthostatic hypotension and fainting. A medical student checking blood pressure using a sphygmomanometer and stethoscope. Arterial pressure is most commonly measured via a sphygmomanometer, which historically used the height of a column of mercury to reflect the circulating pressure.[32] Blood pressure values are generally reported in millimetres of mercury (mmHg), though aneroid and electronic devices do not use mercury. For each heartbeat, blood pressure varies between systolic and diastolic pressures. Systolic pressure is peak pressure in the arteries, which occurs near the end of the cardiac cyclewhen the ventricles are contracting. Diastolic pressure is minimum pressure in the arteries, which occurs near the beginning of the cardiac cycle when the ventricles are filled with blood. An example of normal measured values for a resting, healthy adult human is 120 mmHgsystolic and 80 mmHg diastolic (written as 120/80 mmHg, and spoken [in the US and UK] as â€Å"one-twenty over eighty†). Systolic and diastolic arterial blood pressures are not static but undergo natural variations from one heartbeat to another and throughout the day (in a circadian rhythm). They also change in response to stress, nutritional factors, drugs, disease, exercise, and momentarily from standing up. Sometimes the variations are large. Hypertension refers to arterial pressure being abnormally high, as opposed to hypotension, when it is abnormally low. Along with body temperature, respiratory rate, and pulse rate, blood pressure is one of the four main vital signs routinely monitored by medical professionals and healthcare providers.[33] Measuring pressure invasively, by penetrating the arterial wall to take the measurement, is much less common and usually restricted to a hospital setting. The noninvasive auscultatory and oscillometric measurements are simpler and quicker than invasive measurements, require less expertise, have virtually no complications, are less unpleasant and less painful for the patient. However, noninvasive methods may yield somewhat lower accuracy and small systematic differences in numerical results. Noninvasive measurement methods are more commonly used for routine examinations and monitoring. A minimum systolic value can be roughly estimated by palpation, most often used in emergency situations, but should be used with caution.[34] It has been estimated that, using 50% percentiles, carotid, femoral and radial pulses are present in patients with a systolic blood pressure > 70 mmHg, carotid and femoral pulses alone in patients with systolic blood pressure of > 50 mmHg, and only a carotid pulse in patients with a systolic blood pressure of > 40 mmHg.[34] A more accurate value of systolic blood pressure can be obtained with a sphygmomanometer and palpating the radial pulse.[35] The diastolic blood pressure cannot be estimated by this method.[36] The American Heart Association recommends that palpation be used to get an estimate before using the auscultatory method. Auscultatory method aneroid sphygmomanometer with stethoscope Mercury manometer The auscultatory method (from the Latin word for â€Å"listening†) uses a stethoscope and asphygmomanometer. This comprises an inflatable (Riva-Rocci) cuff placed around the upperarm at roughly the same vertical height as the heart, attached to a mercury or aneroidmanometer. The mercury manometer, considered the gold standard, measures the height of a column of mercury, giving an absolute result without need for calibration and, consequently, not subject to the errors and drift of calibration which affect other methods. The use of mercury manometers is often required in clinical trials and for the clinical measurement of hypertension in high-risk patients, such as pregnant women. A cuff of appropriate size is fitted smoothly and snugly, then inflated manually by repeatedly squeezing a rubber bulb until the artery is completely occluded. Listening with the stethoscope to the brachial artery at the elbow, the examiner slowly releases the pressure in the cuff. When blood just starts to flow in the artery, the turbulent flow creates a â€Å"whooshing† or pounding (first Korotkoff sound). The pressure at which this sound is first heard is the systolic blood pressure. The cuff pressure is further released until no sound can be heard (fifth Korotkoff sound), at the diastolic arterial pressure. The auscultatory method is the predominant method of clinical measurement.[37] The oscillometric method was first demonstrated in 1876 and involves the observation of oscillations in the sphygmomanometer cuff pressure[38] which are caused by the oscillations of blood flow, i.e., the pulse.[39] The electronic version of this method is sometimes used in long-term measurements and general practice. It uses a sphygmomanometer cuff, like the auscultatory method, but with an electronic pressure sensor (transducer) to observe cuff pressure oscillations, electronics to automatically interpret them, and automatic inflation and deflation of the cuff. The pressure sensor should be calibrated periodically to maintain accuracy. Oscillometric measurement requires less skill than the auscultatory technique and may be suitable for use by untrained staff and for automated patient home monitoring. The cuff is inflated to a pressure initially in excess of the systolic arterial pressure and then reduced to below diastolic pressure over a period of about 30 seconds. When blood flow is nil (cuff pressure exceeding systolic pressure) or unimpeded (cuff pressure below diastolic pressure), cuff pressure will be essentially constant. It is essential that the cuff size is correct: undersized cuffs may yield too high a pressure; oversized cuffs yield too low a pressure. When blood flow is present, but restricted, the cuff pressure, which is monitored by the pressure sensor, will vary periodically in synchrony with the cyclic expansion and contraction of the brachial artery, i.e., it will oscillate. The values of systolic and diastolic pressure are computed, not actually measured from the raw data, using an algorithm; the computed results are displayed. Oscillometric monitors may produce inaccurate readings in patients with heart and circulation problems, which include arterial sclerosis, arrhythmia, preeclampsia, pulsus alternans, and pulsus paradoxus. In practice the different methods do not give identical results; an algorithm and experimentally obtained coefficients are used to adjust the oscillometric results to give readings which match the auscultatory results as well as possible. Some equipment uses computer-aided analysis of the instantaneous arterial pressure waveform to determine the systolic, mean, and diastolic points. Since many oscillometric devices have not been validated, caution must be given as most are not suitable in clinical and acute care settings. The term NIBP, for non-invasive blood pressure, is often used to describe oscillometric monitoring equipment. Continuous noninvasive techniques (CNAP) Continuous Noninvasive Arterial Pressure (CNAP) is the method of measuring arterial blood pressure in real-time without any interruptions and without cannulating the human body. CNAP combines the advantages of the following two clinical â€Å"gold standards†: it measures blood pressure continuously in real-time like the invasive arterial catheter system and it is noninvasive like the standard upper arm sphygmomanometer. Latest developments in this field show promising results in terms of accuracy, ease of use and clinical acceptance. Non-occlusive techniques: the Pulse Wave Velocity (PWV) principle Since the 90s a novel family of techniques based on the so-called Pulse wave velocity (PWV) principle have been developed. These techniques rely on the fact that the velocity at which an arterial pressure pulse travels along the arterial tree depends, among others, on the underlying blood pressure.[40] Accordingly, after a calibration maneuver, these techniques provide indirect estimates of blood pressure by translating PWV values into blood pressure values.[41] The main advantage of these techniques is that it is possible to measure PWV values of a subject continuously (beat-by-beat), without medical supervision, and without the need of inflating brachial cuffs. PWV-based techniques are still in the research domain and are not adapted to clinical settings. For some patients, blood pressure measurements taken in a doctor’s office may not correctly characterize their typical blood pressure.[42] In up to 25% of patients, the office measurement is higher than their typical blood pressure. This type of error is calledwhite-coat hypertension (WCH) and can result from anxiety related to an examination by a health care professional.[43] The misdiagnosis of hypertension for these patients can result in needless and possibly harmful medication. WCH can be reduced (but not eliminated) with automated blood pressure measurements over 15 to 20 minutes in a quiet part of the office or clinic.[44] Debate continues regarding the significance of this effect.[citation needed] Some reactive patients will react to many other stimuli throughout their daily lives and require treatment. In some cases a lower blood pressure reading occurs at the doctor’s office.[45] Ambulatory blood pressure devices that take readings every half hour throughout the day and night have been used for identifying and mitigating measurement problems like white-coat hypertension. Except for sleep, home monitoring could be used for these purposes instead of ambulatory blood pressure monitoring.[46] Home monitoring may be used to improve hypertension management and to monitor the effects of lifestyle changes and medication related to blood pressure.[6] Compared to ambulatory blood pressure measurements, home monitoring has been found to be an effective and lower cost alternative,[46][47][48] but ambulatory monitoring is more accurate than both clinic and home monitoring in diagnosing hypertension. Ambulatory monitoring is recommended for most patients before the start of antihypertensive drugs.[49] Aside from the white-coat effect, blood pressure readings outside of a clinical setting are usually slightly lower in the majority of people. The studies that looked into the risks from hypertension and the benefits of lowering blood pressure in affected patients were based on readings in a clinical environment. When measuring blood pressure, an accurate reading requires that one not drink coffee, smoke cigarettes, or engage in strenuous exercise for 30 minutes before taking the reading. A full bladder may have a small effect on blood pressure readings; if the urge to urinate arises, one should do so before the reading. For 5 minutes before the reading, one should sit upright in a chair with one’s feet flat on the floor and with limbs uncrossed. The blood pressure cuff should always be against bare skin, as readings taken over a shirt sleeve are less accurate. During the reading, the arm that is used should be relaxed and kept at heart level, for example by resting it on a table.[50] Since blood pressure varies throughout the day, measurements intended to monitor changes over longer time frames should be taken at the same time of day to ensure that the readings are comparable. Suitable times are: †¢ immediately after awakening (before washing/dressing and taking breakfast/drink), while the body is still resting, †¢ immediately after finishing work. Automatic self-contained blood pressure monitors are available at reasonable prices, some of which are capable of Korotkoff’s measurement in addition to oscillometric methods, enabling irregular heartbeat patients to accurately measure their blood pressure at home. Arterial blood pressure (BP) is most accurately measured invasively through an arterial line. Invasive arterial pressure measurement with intravascular cannulae involves direct measurement of arterial pressure by placing a cannula needle in an artery (usually radial, femoral,dorsalis pedis or brachial). The cannula must be connected to a sterile, fluid-filled system, which is connected to an electronic pressure transducer. The advantage of this system is that pressure is constantly monitored beat-by-beat, and a waveform (a graph of pressure against time) can be displayed. This invasive technique is regularly employed in human and veterinary intensive care medicine, anesthesiology, and for research purposes. Cannulation for invasive vascular pressure monitoring is infrequently associated with complications such as thrombosis, infection, andbleeding. Patients with invasive arterial monitoring require very close supervision, as there is a danger of severe bleeding if the line becomes disconnected. It is generally reserved for patients where rapid variations in arterial pressure are anticipated. Invasive vascular pressure monitors are pressure monitoring systems designed to acquire pressure information for display and processing. There are a variety of invasive vascular pressure monitors for trauma, critical care, and operating room applications. These include single pressure, dual pressure, and multi-parameter (i.e. pressure / temperature). The monitors can be used for measurement and follow-up of arterial, central venous, pulmonary arterial, left atrial, right atrial, femoral arterial, umbilical venous, umbilical arterial, and intracranial pressures. Further information: Fetal circulation#Blood pressure In pregnancy, it is the fetal heart and not the mother’s heart that builds up the fetal blood pressure to drive its blood through the fetal circulation. The blood pressure in the fetal aorta is approximately 30 mmHg at 20 weeks of gestation, and increases to approximately 45 mmHg at 40 weeks of gestation.[51] The average blood pressure for full-term infants: Systolic 65–95 mm Hg Diastolic 30–60 mm Hg[52] Blood pressure is the measurement of force that is applied to the walls of the blood vessels as the heart pumps blood throughout the body.[53] The human circulatory system is 400,000 miles long, and the magnitude of blood pressure is not uniform in all the blood vessels in the human body. The blood pressure is determined by the diameter, flexibility and the amount of blood being pumped through the blood vessel.[53] Blood pressure is also affected by other factors including exercise, stress level, diet and sleep. The average normal blood pressure in the brachial artery, which is the next direct artery from the aorta after the subclavian artery, is 120mmHg/80mmHg. Blood pressure readings are measured in millimeters of mercury (mmHg) using sphygmomanometer. Two pressures are measured and recorded namely as systolic and diastolic pressures. Systolic pressure reading is the first reading, which represents the maximum exerted pressure on the vessels when the heart contracts, while the diastolic pressure, the second reading, represents the minimum pressure in the vessels when the heart relaxes.[54] Other major arteries have similar levels of blood pressure recordings indicating very low disparities among major arteries. The innominate artery, the average reading is 110/70mmHg, the right subclavian artery averages 120/80 and the abdominal aorta is 110/70mmHg.[55] The relatively uniform pressure in the arteries indicate that these blood vessels act as a pressure reservoir for fluids that are transported within them. Pressure drops gradually as blood flows from the major arteries, through the arterioles, the capillaries until blood is pushed up back into the heart via the venules, the veins through the vena cava with the help of the muscles. At any given pressure drop, the flow rate is determined by the resistance to the blood flow. In the arteries, with the absence of diseases, there is very little or no resistance to blood. The vessel diameter is the most principal determinant to control resistance. Compared to other smaller vessels in the body, the artery has a much bigger diameter (4mm), therefore the resistance is low.[55] In addition, flow rate (Q) is also the product of the cross-sectional area of the vessel and the average velocity (Q = AV). Flow rate is directly proportional to the pressure drop in a tube or in this case a vessel. ∆P ÃŽ ± Q. The relationship is further described by Poisseulle’s equation ∆P = 8 µlQ/Ï€r4.[56] As evident in the Poisseulle’s equation, although flow rate is proportional to the pressure drop, there are other factors of blood vessels that contribute towards the difference in pressure drop in bifurcations of blood vessels. These include viscosity, length of the vessel, and radius of the vessel. Factors that determine the flow’s resistance as described by Poiseuille’s relationship: †¢ ∆P: pressure drop/gradient †¢  µ: viscosity †¢ l: length of tube. In the case of vessels with infinitely long lengths, l is replaced with diameter of the vessel. †¢ Q: flow rate of the blood in the vessel †¢ r: radius of the vessel Assuming steady, laminar flow in the vessel, the blood vessels behavior is similar to that of a pipe. For instance if p1 and p2 are pressures are at the ends of the tube, the pressure drop/gradient is:[57] In the arterioles blood pressure is lower than in the major arteries. This is due to bifurcations, which cause a drop in pressure. The more bifurcations, the higher the total cross-sectional area, therefore the pressure across the surface drops. This is why the arterioles have the highest pressure-drop. The pressure drop of the arterioles is the product of flow rate and resistance: ∆P=Q xresistance. The high resistance observed in the arterioles, which factor largely in the ∆P is a result of a smaller radius of about 30  µm.[58] The smaller the radius of a tube, the larger the resistance to fluid flow. Immediately following the arterioles are the capillaries. Following the logic obvserved in the arterioles, we expect the blood pressure to be lower in the capillaries compared to the arterioles. Since pressure is a function of force per unit area, (P = F/A), the larger the surface area, the lesser the pressure when an external force acts on it. Though the radii of the capillaries are very small, the network of capillaries have the largest surface area in the vascular network. They are known to have the largest surface area (485mm) in the human vascular network. The larger the total cross-sectional area, the lower the mean velocity as well as the pressure.[55] Reynold’s number also affects the blood flow in capillaries. Due to its smaller radius and lowest velocity compared to other vessels, the Reynold’s number at the capillaries is very low, resulting in laminar instead of turbulent flow.[59] The Reynold’s number (denoted NR or Re) is a relationship that helps determine the behavior of a fluid in a tube, in this case blood in the vessel. The equation for this dimensionless relationship is written as:[56] †¢ Ï : density of the blood †¢ v: mean velocity of the blood †¢ L: characteristic dimension of the vessel, in this case diameter †¢ ÃŽ ¼: viscosity of blood The Reynold’s number is directly proportional to the velocity and diameter of the tube. Note that NR is directly proportional to the mean velocity as well as the diameter. A Reynold’s number of less than 2300 is laminar fluid flow, which is characterized by constant flow motion, whereas a value of over 4000, is represented as turbulent flow. Turbulent flow is characterized as chaotic and irregular flow.[56] Disregulation disorders of blood pressure control include high blood pressure, blood pressure that is too low, and blood pressure that shows excessive or maladaptive fluctuation. Overview of main complications of persistent high blood pressure. Arterial hypertension can be an indicator of other problems and may have long-term adverse effects. Sometimes it can be an acute problem, for examplehypertensive emergency. All levels of arterial pressure put mechanical stress on the arterial walls. Higher pressures increase heart workload and progression of unhealthy tissue growth (atheroma) that develops within the walls of arteries. The higher the pressure, the more stress that is present and the more atheroma tend to progress and the heart muscle tends to thicken, enlarge and become weaker over time. Persistent hypertension is one of the risk factors for strokes, heart attacks,heart failure and arterial aneurysms, and is the leading cause of chronic renal failure. Even moderate elevation of arterial pressure leads to shortened life expectancy. At severely high pressures, mean arterial pressures 50% or more above average, a person can expect to live no more than a few years unless appropriately treated.[60] In the past, most attention was paid to diastolic pressure; but nowadays it is recognised that both high systolic pressure and high pulse pressure (the numerical difference between systolic and diastolic pressures) are also risk factors. In some cases, it appears that a decrease in excessive diastolic pressure can actually increase risk, due probably to the increased difference between systolic and diastolic pressures (see the article on pulse pressure). If systolic blood pressure is elevated (>140) with a normal diastolic blood pressure ( Blood pressure. (2017, Feb 22).
