Callista Roy

...“Nursing Theorists’ Grading Criteria” document, located on the Materials page of the student Web site. Name: Steve Early Theorist Selected: Sr. Callista Roy Description of Theory: Sister Callista Roy believed that “Humans are bio-psycho-social beings existing within an environment. Needs are created within interrelated adaptive modes: physiological, self-concept, role function, and interdependence” (Taylor 74). Sr. Roy believed that the patient’s modes of adaption were partly innate and partly acquired behaviors; if the behaviors are appropriately applied there is an increase in health restoration. According to "Nursing Theory" (2011), The nursing theory was named “The Adaptation Model,” and includes a “six step nursing process: 1) The first level of assessment, which addresses the patient's behavior, 2)The second level of assessment, which addresses the patient's stimuli, 3)Diagnosis of the patient, 4)Setting goals for the patient's health, 5)Intervention to take actions in order to meet those goals, and 6)Evaluation of the result to determine if goals were met.” Theory’s Historical background: Sister Callista Roy is considered a living legend as she has been awarded various acknowledgements for her contributions to nursing. Sr. Roy developed the Adaptation Model in 1976, and for the past 36 years, she has been researching and updating her work, literally adapting to the ever-changing world and social needs. She has......

Roy Peter Clark's Writing Tools

...Most writers have gotten the feeling that their paper is not good enough and begin to attack their own piece of work, well before they are even finished. In Roy Peter Clark’s Writing Tools: 50 Essential Strategies for Every Writer, he communicates that silencing this criticism in the beginning can get more done compared to having the criticism take over in the beginning. I agree with Clark on this technique when approaching papers because criticism taken in a negative way can impact a writer’s overall work. Along with self-criticism, learning how to take criticism from others and using it to improve a written work can bring better results. Criticism will always be there but it is up to the writer to be able to hush the voice that critiques the work. Writing freely can help the writer concentrate on what he or she is trying to convey on their paper. It may seem odd but just writing freely can get more accomplished than just reviewing everything that has been written so far. Preventing to look back at the work a writer has so far can be difficult since he or she will want to know if what they wrote so far is good enough. Is it good enough? The question that constantly comes up when writing an essay or anything in general. This question can either make you, or break you. As a writer progresses in their work, the inner critic can begin to get louder and louder. If the inner critic cannot be silenced, it can help to just stop what you are doing and take......

...Sister Callista Roy Adaptation Model (RAM) is defined as helping a person respond positively to changes, either physical or social environment. People have mutual relationships with the world and God. People use human creative abilities of awareness, enlightenment, and faith, according to Masters RN, DNS (2010), (Chapter 10). Roy’s theory provides a systematic approach to nursing practice known as the nursing process. Ram utilizes a bi-level assessment to problem solve the nursing process in everyday patient care. Assessment of Behavior * The first step of the nursing process, which involves gathering data about the behavior of the person as an adaptive system in each of the adaptive modes("Nursing Theories", 2012). Assessment of Stimuli * The second step of the nursing process involves the identification of internal and external stimuli that are influencing the person’s adaptive behaviors. * Stimuli are classified as: 1. Focal- those most immediately affecting the person, 2. Contextual-all other stimuli present that are affecting the situation 3. Residual- other stimuli whose effect on the situation are unclear. ("Nursing Theories", 2012). Nursing Diagnosis * Step three of the nursing process involves the formulation of statements that interpret data about the adaptation status of the person, including the behavior and most relevant stimuli ("Nursing Theories", 2012).

Arundhati Roy and the God of All Things

...Mary Rosefern Montecalvo Arundhati Roy and The God of Small Things Asian Literature – Finals Paper Does everything really happen for a reason? Or do they merely occur at random? These are but two of several questions that Arundhati Roy left me with after I finished reading her novel The God of Small Things. Roy quoted contemporary writer John Berger for her novel’s epigraph when he said: "Never again will a single story be told as though it's the only one." Readers would agree that it is perfect for a story that is told in a non-linear manner with multiple perspectives. Synopsis of the Novel: Mostly set in a village named Ayemenem in India, the story tells about the childhood of fraternal twins Estha (a girl) and Rahel (a boy) when they were 7 years old in 1969 and then 24 years later in 1996. Ammu, the twins’ mother, also grew up in Ayemenem with her parents Pappachi and Mammachi. She has a brother named Chacko who went to study at Oxford and married a white woman named Margaret. They have a daughter named Sophie. While she's pregnant, Margaret falls for a guy named Joe, whom she marries after divorcing Chacko. Chacko is heartbroken and moves back to Ayemenem. Ammu also used to be married before she went back to Ayemenem with the twins in tow. Her husband’s name was Baba and they got divorced when Baba informed her about an indecent proposal thought up by his boss. Ammu did not agree to play along with it and in doing so, got herself beat up by Baba....

...studies and enhance application of didactic course content to nursing practice. Students tend to undervalue the contributions of a nursing conceptual model to guide practice. By integrating a nursing conceptual model into the organization of course content and construction of case studies, students are exposed to how conceptual models can guide nursing practice. The purpose of this column is to explore the use of case studies for a senior level medical-surgical nursing course constructed within the context of the Roy adaptation model. Roy Adaptation Model The Roy adaptation model is a conceptual model of nursing that provides a solid foundation for nursing practice (Roy & Andrews, 1999). The philosophical and scientific assumptions of Roy’s model assert that the person is a holistic Nursing Science Quarterly, Vol. 20 No. 4, October 2007, 324-326 DOI: 10.1177/0894318407307159 © 2007 Sage Publications adaptive system in constant interaction with the environment. Roy and Andrews (1999) described people as biopsychosocial beings who adapt to environmental stimuli. Adaptation is defined as “the process and outcome whereby thinking and feeling persons, as individuals or in groups, use conscious awareness and choice to create human and environmental integration” (p. 30). The environment is the source of focal, contextual, and residual stimuli. The focal stimuli are the internal and external factors that immediately confront the person, family, or other group.

Roy and Johnson Comparison of Nursing Theory

...The purpose of this essay is to compare and contrast nursing metaparadigms formulated by Sister Callista Roy’s Adaptation Model and Dorothy Johnson: The Behavioral System Model. These two theorist are identified as grand theorist of the post-positivist era (1950’s-1990’s). The contrast and comparison is structured as Roy’s and Johnson definition of person, health, environment and nursing. Roy defines persons as an adaptive systems with cognation and regulatory subsystems working together to continue adaptation. Roy uses four modes of adaptation (physiological, self-concept, role function, and interdependence) that has to stay balance in order for the person to function at an optimal level. Johnson defines persons as behavioral systems with seven substructures (security, recognition, basic body supply, waste evacuation, sexual needs, defense, and fulfillment) needs to balance to prevent illness. Roy’s model is adaptive and Johnson’s theory of person is reactive to internal/external impulses. Roy defines environment as all conditions and all states of affairs in one’s life that affect development and behavior. Johnson explains environment as internal and external surrounding. Both theorist environments are influenced by one’s current situations that are fixed and those surrounding that are self-restrained. Johnson’s explains health as an adequate and capable function system. Johnson also defines health as observable system balance and security. Roy’s health is the......

Ta-Nehisi Coates Position Paper

...Position Paper #1 After reading this week’s articles, I have found that Ta-Nehisi Coates brings to light many facts about how being black in this country has been very hard since we go here in the 1600s. Not only does he talk about the hardships and basically terrorism of black slaves in the south, but he also talks about how blacks in the north also had to face terrible racism in ways that didn’t necessarily have to do with the then traditional field picking. Black Americans in the north were punished by whites in ways that not only affected the one generation but also the generations to come as they were put in debt and taken granted for everything they owned more than one time. The position that Coates makes for reparations is very well written and serves justice for all the bad that has been happening to blacks since we came to this country. One thing that I found interesting was when he was talking about the federal Housing Authority in Chicago in the mid 1930’s. The FHA created a map that was color coded with red and green. In the green areas of the map they were marked with an “A” meaning in demand, in other words a place where very little or no blacks lived at all. The other areas of the map were blacks were present were giving the letter ”D” and were colored red, which meant The FHA were not giving any help too whatsoever. The article said that black people were considered contagious. It is very disturbing to know that our federal government would do such......

Roy Jennkins

...Roy Jenkins The son of a Welsh coal miner, Roy Jenkins later became a union official and Labour MP. He also served with distinction in World War II. Elected to Parliament as a Labour member in 1948, he served in several major posts in Harold Wilson's First Government. As Home Secretary from 1965–1967, he sought to build what he described as "a civilised society", with measures such as the effective abolition in Britain of capital punishment and theatre censorship, the decriminalisation of homosexuality, relaxing of divorce law, suspension of birching and the legalisation of abortion. As Chancellor of the Exchequer from 1967–1970, he pursued a tight fiscal policy. On 8 July 1970, he was elected Deputy Leader of the Labour Party, but resigned in 1972 because he supported entry to the Common Market, while the party opposed it. He was elected to the House of Commons in a 1948 by-election as the Member of Parliament for Southwark Central. His constituency was abolished in boundary changes for the 1950 general election, when he stood instead in the new Birmingham Stechford constituency. He won the seat and represented the constituency until 1977. Once Jenkins took office as Home Sectary – the youngest Home Secretary since Churchill – he immediately set about reforming the operation and organisation of the Home Office. From 1967 to 1970 Jenkins served as Chancellor of the Exchequer, replacing James Callaghan following the devaluation crisis of November 1967. He quickly gained a......

Roy Cohn Charactersation

...Charcerisation Roy Cohn In the play Tony Kushner-Angels in America_ A Gay Fantasia on Nationthe character Ron Cohn is presented at as a homosexual lawyer. Rohn Cohn also creates the impression that he is a man of great influence. He owns an office and impressive furniture. He highly values the father- son relationship whereas he points out that he considers that the mother-son relationship is not of great importance for a grown man. He listens to chaotic music , usually speaks in a load voice and feels rather confident of himself. He had many different male sexual partners but does not describe himself as homosexual. However, he lies about the fact that he is infected with AIDS and states that the has a liver disorder . This is one example why his character is demonstrated ambiguous. Another example is that Ron is not religious and does not believe that the world is a good place, yet he says that he loves god and that god loves him. Moreover he hates communism but admires the relationship of Marx and Engels He is also characterized by his impudent attitude towards his doctor Henry whom he threatens because due to Ron’s illnesses he considers Ron to be homosexual.

He is aware of the fact that this was illegal but does not really care about it. During the play is character gets more and more besotted by this power......

The author in this column describes this work in two formats. Essential details of two areas of research are presented in episodic form—the first is work on secondary analysis of Roy model-based research over 40 years and the author’s study of persons’ cognitive recovery from mild head injury.The second is a project on re-conceptualizing coping and adaptation processing in sequential detail within the context of work in the field and the significance of on-going work for nursing practice. Keywords adaptation, coping, middle-range theory, research, Roy adaptation model The story of research based on the Roy adaptation model (RAM) can be told in many ways. When asked to write about research based on the RAM in the past 25 years I considered the major events of those years and also how to organize a description of the resulting research. First, I considered that it was 20 years ago that the first group presented a synthesis and critique of studies based on the RAM by five different investigators (Pollock et al., 1991).

Roy Adaptation Theory

...MODEL Nursing theory is an organized framework of concepts that are designed to guide nursing practice and provide a foundation for clinical decision-making. There are many different types of nursing theories. This present paper will focus on one of the Grand theories, the Roy Adaptation model (RAM). The paper is divided into four main sections focusing on the importance of the RAM; summary of key concepts; view of RAM on specialization; and conclusion. There has been an evolution of nursing practice from when Florence Nightingale started. Nurses used to take direct medical direction to an evolution of independence. Today, advanced practice nurses are PHD, DNP, researchers, nurse practitioners, leadership positions in health care organizations, and education . The independence of the nursing profession has occurred in part due to an evolution of nursing theories. The importance of the nursing theories is that they provide framework for nursing practice. There are more than thirty different theorists who have helped contribute to the process. Broadly, these thirty theories can be divided into three major categories Grand theory, Middle theory, and practice. The present paper focuses on the Roy Adaptation Model (RAM) of the Grand Theory. This was chosen as it approaches the care of the patient using a scientific and holistic approach, which aligns with my personal practice as a nurse and belief system. Initially, this model was considered a systems approach. There......

Reverie by Roy Lichtenstein

...Reverie by Roy Lichtenstein Roy Lichtenstein was an American artist who was an influential part of the Pop Art movement in the 1960s. Roy Lichtenstein was born in New York in 1923 and he has created some of the most well-known Pop Art paintings and artworks. An example of his artwork is “Reverie”, it is a screen print by Roy Lichtenstein in 1965 in his iconic comic strip art style. “Reverie” by Roy Lichtenstein shows social commentary of mass production through the art movement it’s in, the technique used, the subject matter. “Reverie” is an example of an artworks that is part of the Pop Art movement. Pop Art developed in the early 1960s as a response to abstract expressionism. It was originally a British movement in the mid 1950s but it became a movement that became a social commentary on the mass-production and unoriginality of the culture in America. Artists in the movement used images or production techniques of everyday consumer life in America. In Lichtenstein ‘s case, he mimicked the style of comics in a way in which it seems to be made by a machine and not by hand, such technique is presented in “Reverie”. Pop Art glorified the everyday, making everyday objects and subjects into high art. It used commercial art as subject matters in painting. Pop art called attention to consumer projects as it mimicked the increasing advertisements, but it also served to glorify them as idealized images of contemporary culture. Pop art, according to Lichtenstein, was art that......

Roy Analysis in Blade Runner

...Chancellor Instructor Hubbard Liba 102 “Multifaceted” Hampton Fincher and David Webb Peoples’ complex screenplay and Ridley Scott’s use of film noir combine together to produce Roy Batty, a character out of Blade Runner, whose diverse personality reflects Jesus Christ, Adam, and Lucifer. As a result, Roy Batty, is much more multifaceted than the heartless, man killing machine that is seen at first glance by an audience. Because Roy reflects Jesus Christ, Adam, and Lucifer, three religious icons, there is an unlimited amount of religious subtext in the film Blade Runner. Hampton Fincher and David Webb Peoples use these religious allegories to hinder a direct and understandable message from the film’s narrative. Therefore, Fincher and Peoples took their complex writing to a deeper level than most screen writers by denying the audience a straightforward interpretation of Roy Batty. One example is the allegory of the creation story and the fall of man. Parallels from the creation story are seen time and time again throughout the film, which is one way Roy’s character relates to the Biblical character, Adam (Gravett, pg. 38). In the Bible, Adam and Eve were forbidden to eat from the tree of knowledge of good and evil as it is stated in Genesis 2: 16-17: “And the LORD God commanded the man, ‘You are free to eat from any tree in the garden; but you must not eat from the tree of the knowledge of good and evil, for when you eat of it you will surely die.’"...
