Qualitative Study on COPD Essay Example for Free

Qualitative Study on COPD Essay This is a qualitative study conducted at the University of Texas Health Science Center at Tyler as a randomized controlled trial to determine the effectiveness of a lifestyle behavioral intervention to increase physical activity among patients with moderate to severe COPD. (Wortz, K. 2012) 54 patients of age 45 or older were randomly selected from April 2010 through January 2011 using a patient registry database with a coded diagnosis of COPD along with physician referrals. Data collection consisted of: baseline, demographic, clinical and self-management needs, smoking status, spirometry, 6-min walk distance, BMI, Obstruction, SOB, Exercise Capacity (BODE) index, Chronic Respiratory Questionnaire (CRQ); which includes 10 open ended questions and Geriatric Depression Scale. A sample of 47 interviews with the mean age of 68.4 years old, 53% male, 87% white were used in the analysis. 57.5% has moderate COPD, 31.9% sever COPD, and 10.6% very severe COPD. (Wortz, K. 2012) The results of this analysis suggest that the content of self-management support with COPD should focus on addressing patients’ fears associated with the uncertainty, progression, suffering of their disease, expectations about overcoming or replacing losses, their needs for improved health literacy and their desire for improved care. Attention to these areas may enhance patient self-efficacy and motivation to improve self management.

Ball Bearings :: essays research papers

The object of ball bearings (and roller bearings) is the substitution of pure rolling motion for plain sliding friction. Ball Bearings rely on the rolling motion of hardened steel balls to absorb loads. This rolling motion produces far less friction than the sliding motion. These steel balls are held in circular rows between an outer and inner ring, which have raceways, or slots, grooved into them to guide the balls. Ball bearings are available in both filling-slot and no filling-slot types. Other types of bearings have developed from these basic designs, like double-row and deep groove bearings, to handle specific application. No filling-slot bearings have a deep uninterrupted raceway, which allows them to carry both high radial loads as well as moderate Thrust loads. Filling-slot bearings have more balls than no filling bearings of comparable size. This gives them a higher radial load capacity, but Thrust loads must be light. Types of Ball bearing systems: Rigid single row ball bearing. - Basic type of bearing widely used. The balls run in comparatively deep grooved tracks, which make the bearing suitable for both radial (journal) load and axial thrust load. The bearing provides location of the shaft in relation to the housing when provided with suitable means of clamping. Rigid single row bearing with filling slots for balls. - This bearing contains more balls than the standard type and can therefore take heavier radial loads but only limited thrust. Rigid double row bearing. - For heavy radial loads and to provide greater rigidity. Requires accurate location if used in conjunction with another bearing. Self-aligning double row bearing. - For applications in which slight deflections cannot be avoided when rotating. Aligning single row bearing. - This bearing will correct initial angular misalignment between shaft and housing but is not designed to accommodate shaft deflection or misalignment when rotating. Angular contact single row bearing. - Gives precise axial location under thrust load. May be used in pairs to accommodate thrust in either direction. Duplex bearing. - Used to take heavy thrust in either direction or some radial load.

Explain how Hill and Golding present death in I’m the King of the Castle and Lord of the Flies respectively? Essay

Hill and Golding both utilise the techniques of symbolism, varied settings and physical death of the character to present death. Overall I think that Hill generally presents death more effectively than Golding, because she generally provides more development throughout her novel, which ultimately leads to the death of Kingshaw. Hill and Golding both use the techniques of symbolism dead stating that â€Å"the inside of its mouth was scarlet† with the adjective â€Å"scarlet† interesting as it has connotations of death and of blood. I think this description of the crow is also a subtle form of prolepsis as the crow is initially portrayed as a normal crow, but as Hill describes the crow further; it is evidently a symbol of death, much like Warings. What is interesting to note about the crow is that it is also described as having â€Å"ragged black wings†- the word ragged could symbolise the aftermath of violence, much like Kingshaw’s exposure to violence later on in the novel and the adjective black is a symbol of death. Another aspect of symbolism regarding the crow is when the crow â€Å"circles over Kingshaw†, symbolically death looms over Kingshaw. This is comparable to the symbolism of death in Lord of the Flies where â€Å"The Lord of the Flies† also symbolises death: one example of this is when the Lord of the Flies states â€Å"we’re going to have fun†- it is a statement, rather than a question, an imperative. The â€Å"fun† that is described refers to evil, ultimately the death of Simon. Another description of the Lord of the Flies describes that is particularly important is when Simon looks at the Lord of the Flies and sees â€Å"blackness† within, a â€Å"blackness that spread†. Perhaps this symbolises not only death, but death spreading throughout the island as other characters are killed. I feel this description also has significance because both Hill and Golding use â€Å"colours† to symbolise death, the colour black. The authors also differ as Hills descriptions are far more graphical, for example the crow, whereas Golding is far more subtle in his description of The Lord of the Flies. I believe that Hills graphic description is more effective at portraying death, her descriptions are far more explicit but some readers may argue this to be a disadvantage as her symbols are too clichà ©d. I think Golding is not as effective because his descriptions are a little more implicit, and hence loses some of the value that his symbol provides in portraying death. Another way in which Hill shows death is through the use of settings. Warings is described as â€Å"being in full night† with â€Å"the yew branches [†¦] overhanging the windows†. Hills typical gothic description to a modern reader is a clear signal of death, especially the Yew branches which also symbolise death. The â€Å"moonlight† suggests a sense of coldness in Warings, like a dead person for example. Warings is also described as â€Å"dark† and â€Å"damp† which emphasises Hills initial description of Warings. This is comparable to Golding’s description â€Å"of the unfriendly side of the island†- a â€Å"place of terror†. This is an explicit meaning, terror and death are linked. Arguably, Castle Rock is the heart of the â€Å"unfriendly side of the island†, Castle Rock is described as being â€Å"the end of the island†, literally the furthest away from the island once compared to paradise. The word â€Å"end† echoes the end of life- supported by the statement â€Å"we shan’t dream to much hear† , perhaps Golding implicitly stating that no one dreams in Castle Rock because death is the end of dreams. Once again I feel that Hill has been more successful at portraying death. Whilst her terms are clichà ©d, she adds a greater degree of subtlety in her descriptions as well, for example the â€Å"moonlight†, the implicit means have greater depth to them, unlike Golding’s explicit descriptions. Finally Hill also presents death in a physical manner as well as through description, through the death of Kingshaw. When Kingshaw dies, it shows death on a physical level, but it may also have a deeper meaning. It was evident from the start of the book, that Kingshaw’s death loomed, however the death signifies the death of the protagonist and victory for the antagonist. This is arguably the death of â€Å"innocence†. This is comparable to Golding’s portrayal of Piggy’s death, describing Piggy’s moments before his death: â€Å"he heard it before he saw it†- the verb heard suggests once again Piggy’s death always loomed, rather like Kingshaw’s. Unlike the death of Kingshaw however, Piggy’s death signals the death of rational, not innocence. I think that Hill has been more effective at portraying death because her description of Kingshaw creates far more emotion rather than the death of Piggy, Golding’s descriptions are too dull. In summary both authors portray death through the use symbolism, settings and physical death. I think that portrayal of death is very effective, especially Hills description. Hill develops her characters throughout her novel, and when Kingshaw dies it is a genuine shock to the reader. Because of Golding’s lack of development, Piggy’s death is not as emotional as Kingshaw’s.

Ethics and Political Philosophy - 1749 Words

Ethics and Political Philosophy PEC 3 Gabriel Benavides Escriva Hans Jonas, The changed nature of human action This chapter, which is the subject of our study is the first book The principle of responsibility: ethics test for technological civilization, and is titled, The changed character of human action. Hans Jonas studied in this chapter, the changes that have occurred in the history of mankind by emphasizing technological vocation of homo sapiens and what this means from the point of view of the relationship between man and nature and from the viewpoint of relationships among men. Analyzes the characteristics of ethics, old and new challenges and the absence of a future-oriented ethics. The author, Kantian†¦show more content†¦Later, when the gods are banished, the question arises spontaneously replacement by other axioms. The state, market, science or law, are candidates to fill the empty space as the world s computers. While the dispute is not resolved, the usual, disguised by modernity, normalizes the lives of men and immediacy of their daily practices. Later, the colonizing force of modernity in collective life, reach the nearby area of the relationship between men, imposing ethics, according to Jonas, unimagined dimension, responsibility. Not much later, what seemed infinite nature becomes hopelessly vulnerable to unusual and modernity, techniques and technologies. Man now became a causal factor in the extensive system of things. The nature, regarding human responsibility, is certainly nothing new about what ethical theory must reflect. Jonas is questioned on what this new reflection to political ethics: Is it just prudence forbids us to kill the goose that lays the golden eggs or cut the branch on which you are sitting? But who is the one who is in her sitting and perhaps falling into the void? And what is my interest to stay in place or fall? Ethics, understanding its origin anthropocentric, ie coexistence own men, and activities emerged between men, is aimed at humans, for that reason, it defines itself, thus excluding any non-human species.
