Pathophysioloty of a chronic condition - Essay Example On questioning the patient had a localised pain score of 8/10 in her back and a pains in her joints and muscles with a pain score of 4/10. When questioned about her medical history, she stated she had a condition called systemic lupus erythematosus. This is not a condition I had heard of before I, therefore, questioned her more about it. A 20 year-old women patient presented with fatigue, heart palpitations and anxiety. Examining her medical history including her ANA, CBC, skin biopsy of lesions on her legs, complementary series, and anti-DNA antibody test, reveals vessel vasculitis. The results indicate hematocrit: 10.5 g/dL. ANA: 1.640, an elevated Anti-DNA antibody test, 3.8 million/mm3 for red blood cell count, 6000/mm3 of White blood cell count, 35% for Hematocrit, 138,000/mm3 for platelets, 6000/mm3 for White blood cell count, Decreased C3 level at 43 mg/dl for the Complement assay, and a decreased C4 level a 14 mg/dl (Appendix A). The patient’s rheumatoid arthritis factor had been found to be negative with

Productivity Environmental Preference Survey Essay

Productivity Environmental Preference Survey - Essay Example The amount of sound and light in the learning or work environment can have a dramatic effect on the individual’s ability to learn in the environment and be productive. The temperature of the room also has a substantial effect on how an individual is able to process and assimilate information in a given circumstance. These factors can also have an impact on the individual’s motivation to learn and how they learn. Individual motivation can come from external or internal sources and is directly effected by the environmental conditions discussed above, such as lighting, temperature, noise levels, and other various distractions that may present themselves within the environment. Although these variables are all controllable, they are sometimes outside of the scope of the individual’s control and can diminish the individual’s desire to learn. Ensuring that the room is lit to the person’s tolerance levels, noise is kept to their particular preference, and that the room temperature is comfortable or that they have sufficient clothing to stay warm will all help to keep the person motivated and their productivity at a substantial level.

Significance of Evidence Based Practice in Nursing

Significance of Evidence Based Practice in Nursing Nursing is a profession accountable to society for providing high quality cost-effective care for patients and their families (Burns Grove, 2007). This assignment will define evidence based practice and its significance in the nursing process. In addition, it will critically analyse the research article Community Psychiatric Nurses experience of working with people who engage in deliberate self harm carried out by Thompson et al (2008). Furthermore it will define Hierarchy of Evidence and its importance in research studies. A clinical question has been formulated using Population, Intervention, Comparison and Outcome (PICO) and the key words in the article to search for another article which support or contradicts the main review article. Brown defines evidence based practices as the use of the best quality research to deliver an effective quality of care in the best interest of the patient as well as promoting cost effectiveness within the healthcare system (Brown, 1999). In order for health care professionals to deliver the best quality of care, they need to use the combination of evidence based clinical treatments and practices (Lindsay, 2007). Evidence based knowledge is important as it guides and maintains the clinical competencies of health care practitioners and provides a research based explanations to assist patients in the process of clinical decision making (Burns and Grove, 2007). According to Ciliska et al (2005), the skills necessary to provide evidence based solution to a clinical dilemma includes defining the problem, conducting the effective research to locate the best evidence, critically appraising the evidence and considering that evidence and its implications in the context of patients circumstances and values. Research into the experience of community psychiatric nurses working with people who engage in deliberate self-harm was carried out using the qualitative research design, as it is primarily concerned with understanding human beings experiences in a humanistic, interpretive approach (Ronald et al, 2007). The purpose of the research was to understand CPNs experience while they are working with people who deliberately self-harm. In this research it was found suitable as it relies less on non numerical data. A study by Playle (2000) suggest that readers need to read, critically study and evaluate a research article to demonstrate their understanding of research and to identify implications for practice. In this study, Tarling and Crofts (2002)s framework and The Critical Appraisal Skill Programme (CASP) accessed on http://www.phru.nhs.uk/Pages/PHD/CASP.htm has been used to review the strength, credibility, validity and weakness of the above study. The title Community Psychiatric nurses experience of working with people who deliberately self-harm is clear, concise and informative as it reflects the contents of the whole study. Informative titles are important in research process as it allows the reader to identify the research approach (Roe and Webb, 1999), however the title does not reveal the approach which may be seen as a weakness (Dempsey and Dempsey, 2000). The authors of this article are qualified professional with clinical and psychological expertise as well as experience of working with people with mental health problems as Dempsey and Dempsey (2000) suggests that authors should be qualified to carry out a research study and their qualifications should be verified if need be. This may be seen as powerful, hence reliability and credibility of this article is not questionable as they will be perceived as professionals with clinical credibility to eliminate bias (Hoskins et al, 2005). However it can be argued that the community psychiatric nurses had not undertaken psychotherapy training although they had a minimum of eighteen years of experience (Thompson et al, 2008). The abstract is short, brief and concise. According to Parahoo (2006) a research report should begin with an abstract which summarises the major findings of the study as well as attracting the readers attention to read the whole research article thus adding credibility and validity to the report. Lack of clear summary may be seen as a weakness as readers may lose interest in reading the whole article as it may fail to express the important information about the study (Morrison, 1992). According to Newell Burnard (2006), an introduction should clearly define the key words and stating the purpose of the research. This study clearly explains in detail what is meant by deliberate self-harm and yet there is little research into the actual experience of working with people who deliberate self-harm (Thompson et al, 2008). The research used Interpretative Phenomenological Analysis (IPA), which allowed an in-depth exploration of individual personal experience, underpinning the theory of interpretation and interaction which focuses on individuals experiences to the central concern and can only be accessed through IPA (Smith, 1995). According to Streubert and Carpenter (1995), Interpretative is the understanding of life experiences and events and Phenomenology is the appearance of things as lived experiences. This may be seen as strength as it is fundamentally important, as without knowing exactly how the study was carried out, it is difficult for the reader to judge its strengths and weaknesses (Gillis, 2002). In this study, the researchers and the participants were all from the North of England thereby eliminating the theory of ethnography which requires the investigator to learn about a culture and be part of it (Burns and Grove, 2007). The participants were made up of four male and four females from t he community mental health teams who had an average age of forty years and eighteen years of experience of working with people who engage in deliberate self -harm. The researcher did not explain why different age groups did not participate or other ethnic minority groups which limited their findings. For the purpose of this study, a purposive (participants with a specific characteristics (Lindsay, 2007) sample was recruited. According to Parahoo (2006), sampling is important in qualitative research as it seeks to collect valid and reliable data from a small division of the population that would be representative of the whole population. This showed to be suitable to the study which may be seen as reliable and valid although, it can be argued that sampling method may produce biased results. It may be seen as a selective method to fulfil the aims of the study (Streubert-Speziale Carpenter, 2007). Data was collected through semi-structured interview and open-ended questionnaires according to IPA (Smith, 1995). The interviews lasted for forty five minutes to an hour which was guided but did not dictate the exact course of the interview. This was chosen in order to allow the interviewees to talk freely to explain their thoughts and experiences. The method accessed the participants natural attitudes and understanding of deliberate self harm. This enabled certain responses to be questioned in greater depth, while collecting similar data from all the informants as well as creating a relaxed comfortable environment for the interviewees, (Holloway and Wheeler, 2002). However it can be argued that it is a time-consuming method, not just the collecting of the data, but the transcribing and analysis of the data. There are risks of interviewer bias as face to face interviews often require training, (Parahoo, 2006). All interviews were recorded and transcribed verbatim. According to Holloway and Wheeler (2002), researchers must preserve participants words as accurately as possible before analysing the data. The researchers had a chance to replay the tapes several times to improve the quality of the transcripts. The transcripts were then analysed using IPA principals (Smith and Osborn, 2003). The researcher read the transcripts to familiarise with the data, noting down the key words and phrases said by the participants, thus summarising the sample (Rowntree, 1991). The notes were classified in more general term to form initial themes to try and capture the essence of the participants accounts which were then copied to a computer program which assisted in managing connections between the emerging themes but no direct analysis was made. According to Morse and Field (2007), transcripts from different informants should be compared categorised and coded into substantive themes and sub-themes to produce a high degree of interpretation and integration. A master list of themes and subthemes was then produced for transcript which contained a degree of interpretation and integration. The process was repeated on every interview to maintain consistence of data analysis as suggested by Burns and Grove (2007). The themes were highly developed and compared to original text as Speziale Streubert and Carpenter (2007) suggests that researchers needs to move forward and backward between levels until saturation is achieved to ensure a comprehensive understanding of the phenomena. A table was produced for each theme indicating the sub themes and identifying where each transcript could be evidenced. Different methods were employed to ensure trustworthiness and the master themes audited by the three authors including an independent researcher to ensure that themes were warrantable and grounded in the data. Although the researchers have carefully considered how to ensure validity of the study, it is noted that the findings were subject to limitations as all the nurses were experienced white British, limiting the applicability of nurses from other ethnic origins or trained in other countries. In addition, it is a small study based in a small geographical area which limits reliability as well as the generalizability of the results (Meadows, 2004). There is also evidence that there may be differences in assessment practices between different professional groups and different levels of experience, (Weston, 2003). Furthermore, the findings are based on reflective accounts of the experience of working with patients, who self-harm and may therefore be subject to memory bias, (Thompson et al, 2008). The authors recommends further studies to explore the extent of experiences and evaluate further interventions to improve professional awareness of deliberate self-harm as well as training for nurses to provide high standards of care as suggested by NMC (2008). The researcher sought approval from the NHS (National Health Service) ethical and research government as suggested by Parahoo (2006) thus adding credibility. However the research does not specify if consent, was sort from the participants which may appear as a weakness as it important to respect for autonomy and beneficence (Polit and Beck, 2006). Ensuring of confidentiality NHS (2008) of information discussed, was not addressed to the participants before the research was carried out which may have led to withholding of important information which would affect the validity of the report (Clifford, 1997). This can be seen as a weakness in the research. Hierarchy of evidence is the ranking of research methods according to their effectiveness, strength and weaknesses (Ciliska et al, 2005). In the healthcare system, depending on its source, some research methods are considered to be stronger and produce better quality evidence than others hence credibility, reliability and validity differs (Lindsay, 2007). According to Polit Beck (2008), qualitative research falls on level V because of its systematic descriptive of psychological studies Craig and Smyth (2002) suggests the use of PICO (systematic way to identify important ideas in a research article), in formulating a clinical question in health care. P is Population which was Deliberate Self harm I is Intervention which was Not Applicable C is Comparison which was Not Applicable O is Outcome which was CPN experience. To search for the second article clinical question has been formulated using PICO. The following link was used to access the article. Student Portal Log In my studies summon type in key words Go Button. The search was carried out using the key words, CPNs experience in deliberate self harm in all fields and 310 articles were retrieved. The search was limited to product content journals only which retrieved 306 journals. The search was further limited with the number of years from 2009 to 2010 which yielded 35 journals articles. Among the articles, Analysis of Accident and Emergency Doctors Response To Treating People Who Self-Harm was retrieved and read through which supported the reviewed article adding to its strength, validity and credibility. A study by Craig Smythe (2002) suggests the search of electronic database as a method of finding research studies as all journals have indexes that have been converted to electronic databases. The University subscribe to Summon which can be accessed freely by all students which makes it easier to search articles for educational purposes. In conclusion, evidence based knowledge is important in implementation of cost effective nursing intervention and therefore it is the responsibility of health care professionals to critically analyse any piece of evidence for credibility, validity, reliability and its source, in clinical decision making (Brown ,1999). They also have a legal and professional responsibility under the Human Rights Act 1998, Health and Safety 1974, The Consumer Protection 1987 as well as The Duty of Care (NMC 2008).

The Ebola Virus :: Ebola Hemorrhagic Fever

The Ebola Virus INTRODUCTION The most deadly killers on this earth are too small to see with the naked eye. These microscopic predators are viruses. In my report, I will answer many basic questions concerning one of the fastest killing viruses, the Ebola virus. Questions such as "How does it infect its victims?", "How are Ebola victims treated?", "How are Ebola outbreaks controlled?" and many others related to this deadly virus. GENERAL INFORMATION The Ebola virus is a member of the negative stranded RNA viruses known as filoviruses. There are four different strains of the Ebola virus - Zaire (EBOZ), Sudan (EBOS), Tai (EBOT) and Reston (EBOR). They are very similar except for small serological differences and gene sequence differences. The Reston Strain is the only one which does not affect humans. The Ebola virus was named after the Ebola river in Zaire, Africa after its first outbreak in 1976. STRUCTURE When magnified by an electron microscope, the ebola virus resembles long filaments and are threadlike in shape. It usually is found in the form of a "U- shape". There are many 7nm spikes which are 10nm apart from each other visible on the surface of the virus. The average length and diameter of the virus is 920nm and 80nm. The virons are highly variable in length (polymorphic), some attaining lengths as long as 14000nm. The Ebola virus consists of a helical nucleocapsid, which is a protein coat and the nucleic acid it encloses, and a host cell membrane, which is a lipoprotein unit that surrounds the virus and derived form the host cell's membrane. The virus is composed of 7 polypeptides, a nucleoprotein, a glycoprotein, a polymerase and 4 other undesignated proteins. These proteins are synthesized by mRNA that are transcribed by the RNA of the virus. The genome consists of a single strand of negative RNA, which is noninfectious itself. The order of it is as follows: 3' untranslated region, nucleoprotein, viral structured protein, VP35, VP40 glycoprotein, VP30, VP24, polymerase(L), 5' untranslated region. HOW IT INFECTS Once the virus enters the body, it travels through the blood stream and is replicated in many organs. The mechanism used to penetrate the membranes of cells and enter the cell is still unknown. Once the virus is inside a cell, the RNA is transcribed and replicated. The RNA is transcribed, producing mRNA which are used to produce the virus' proteins. The RNA is replicated in the cytoplasm and is mediated by the synthesis of an antisense positive RNA strand which serves as a template for producing additional Ebola genomes. As the infection progresses, the cytoplasm develops "prominent inclusion bodies" which means that

Lesson Observation

PGCE 1 Observation 1 Date 24/11/2009 Author: Gareth Jones Observation of an Experienced Teacher An Evaluation Introduction My first observation was at a4e, which is where I volunteer for 5 hours per week. These hours count towards my teaching hours as part of my PGCE. The teacher delivering the session was Charlotte Faichney who is the Skills for Life specialist. She delivers the Numeracy and Literacy modules at the a4e Wrexham office. The students’s ages ranged from 16 to 18 and were at Entry Level 2 and 3. The session was held in Basic Skills Classroom, which is well equipped, well lit and well maintained. This showed an understanding about ways to maintain a learning environment in which learners feel safe and supported (BK 1. 1) This was my first observation and would count towards the PTLLS module of my PGCE. The session ran for 95 minutes. Planning The aim of the lesson was to introduce the learners to different aspects of handling data through the use of circus skills. The learner’s objectives were to record numerical data, extract and interpret that data and to make comparisons with the use of bar charts. They would have to find the average and the range for a set of data. The lesson plan showed a logical flow from introduction of the session, to the practical exercises, collecting and interpreting the data and the final Q & A session that evaluated the success of planned learning activities (DP 3. 1). These Q & A sections were relevant and acted as a natural stepping stone to progress the lesson. The first Q & A established prior knowledge, while the second assessed the newly acquired knowledge before starting the main activity. The next session re-capped the activity and gave the learners the opportunity to analyse their results. The fourth session enable students the knowledge to calculate arithmetic averages for their sets of data and the last session was a summative assessment of the whole session. This detailed plan really showed how to plan a teaching and learning session (DK 1. 2). Management of Learning Communication, both verbal and demonstrative was clear, concise and always relevant. The teacher was always engaging and confidently controlled the classroom. I noticed that she used open and Socratic questions to draw out answers from the learners. There was strict adherence to the rules of the classroom that were predominantly displayed on a poster. These rules covered behaviour, what the teacher expected from the learners in terms of input and what the learners could expect from the teacher. Mobile phones had to be switched off and food and drink were not allowed. The teacher was proactive and walked confidently around the classroom.. It showed me the importance of establishing and sticking to firm rules and gave me a valuable insight on how beneficial classroom management can be to both the teacher and the learner. The lesson was definitely learner focussed, as all students were fully engaged and participed in collaborative learning activities. Biggs (1994) argues â€Å"The focus should not be on the skills itself, but whether its deployment has the desired effect on student learning. † Learners were encouraged to discuss their findings and the Q & A ensured that the learners had to think about what, and how they could use, what they were learning. Gibbs (1981) states that â€Å"this is one of the qualities displayed by learners with a deep approach†. . Resources The circus skills theme was fun and made the collection and interpretation of data less mundane than it could have been. This highlighted ways to engage, motivate and encourage active participation of learners and learner independence (BK 2. 2). The handouts were clear and relevant, whilst the flipchart provided a good point of reference throughout the session. Although I have used these resources myself, I could see how well thought out and good quality handouts greatly enhanced the learning experience. The flipchart was covered when not in use to prevent distraction. There were three skills to try, which catered for the varying abilities. Information was easily recordable, which meant extraction and interpretation was very manageable. I could see that the impact of resources on effective learning (BK 5. 1) was clearly visible and the emphasis was on the needs of the student. Reece and Walker, (2007, p26) state that a teaching strategy maybe defined as â€Å"a purposeful combination of student activities supported by appropriate resources to provide a particular learning experience (process) and/or to bring about the desired learning (product)† Assessment Initial assessment was carried out by using a Q & A session to establish prior knowledge of tally and bar charts and also of the meaning of mean, mode, range and median. Formative assessment took the form of Q & A about the results from the tally chart exercise, the deliberate omissions from the tutor’s bar graph. The leaner’s swapped graphs and had to interpret each other’s results, which showed ways to develop, establish and promote peer and self assessment (EK (1. 3). The results from calculating the mean, mode, range and median were discussed and an understanding of the terminology was verified. For summative for assessment, we re-visited the flipchart to re-cap on the session, using Q & A to determine which areas the learners required more information on. The session showed the teacher used appropriate forms of assessment and evaluated their effectiveness in producing information useful to the teacher and the learner (EP 1. 1) Conclusion The first thing I noticed was how the layout and environment of the room impacted on the learner’s attitude to the session. They are normally in a nosier more congested classroom and as a whole are generally quite rowdy. They settled quickly and seemed eager to start the session and were asking questions before the session had even began. Once they realised they were going to try various circus skills their level of interest grew even more. It seemed to me to be a great way of delivering a session. They were having fun, learning about collating, recording and extraction of data, carrying out self and peer assessment and obtaining an understanding of various mathematical terms. This technique would be useful in covering differentiation within the classroom. The teacher guided the session, whilst the learners drove it. She was inclusive and took an active part in what was going on. However she stood back as soon as the learners were actively engaged to observe and assess the activity. Most of the learners want to work in factories or retail, so an understanding of sales and production figures, which normally come in the form of charts, is required. Most stock taking is initially carried out using a tally system and knowing how to calculate the mean, range, median and mode is useful in most present day jobs. Most businesses place a huge emphasis on the gathering and interpretation of data. Without detailed and up-to-date information they consider themselves to be â€Å"running blind†. This session has shown me that you don’t just go out and deliver a given subject in its rawest form. I can see the benefits of innovative teaching methods and using visual and kinaesthetic strategies. The use of formative and summative assessment to establish that learning has taken place can not be argued against. Whilst the teacher’s use of peer and self assessment to compliment this strategy underlines the value placed on it. I agree with Reece and Walker (2007, p369), who state that, â€Å"The important thing is that assessment is an integral part of each lesson, the course and of the learning†.

Irish Traditional Music

The Harp The harping tradition in Ireland flourished from medieval times until the seventeenth century. It was fostered and developed among the powerful and wealthy Irish and Anglo-Irish families. Harpers were employed along with poets and orators, known as reacoirs, to provide entertainment for the families. As the families acted as patrons to the harpers, they would often have solo pieces, known as planxties, written in their honour by their harper. One famous song is Planxty Kelly.The occupation of a harper was a very prestigious one. The harping tradition was passed on, father to son, for many years and was one of very few viable career options for blind boys at the time. However, after 1600, as the great families went into decline, there was a loss of patronage and harpers were left unemployed. The harping tradition then became a nomadic one, as harpers would travel from county to county, playing for money and food. There were two styles of harp: the Bardic harp and the Neo-Iris h harp.The Bardic harp had between 29 and 31 strings made of wire, which were played with the nails. Usually around 70cm in height with a curved pillar and a hollow soundbox, the Bardic harp was the more resonant of the two. The Neo-Irish harp typically had 34 strings made of nylon or cat gut, which were played with the pads of the fingers. They were taller (about 91cm in height) than the Bardic harp, but less resonant. In 1792 the Belfast Harp Festival was setup with the aim of preventing the decline of the harping tradition.It consisted of eleven harpers from the age of 15 to 97, playing pieces in their own particular style. One player that was the light of the day was Denis Hempson, age 97, being the oldest player there. Edward Bunting was commissioned by the Belfast Harp Society to record the lifestyles of the harpers as well as recording and writing down the music from the festival to preserve it for future generations. This method, unlike the oral tradition which had existed u p until then, did not allow for particular nuances in style and some of these were lost.There was a harping revival in the second half of the twentieth century. The role of the harp as a traditional instrument was led by Maire Ni Chathasaigh, who had solo albums such as â€Å"The New Strung Harp† and Laoise Kelly who release the album â€Å"Just Harp† Uilleann Pipes The uilleann pipes are the characteristic national Bagpipe of Ireland. Their current name (they were earlier known in English as â€Å"union pipes†) is a part translation of the Irish language term pioba uilleann (literally, â€Å"pipes of the elbow†), from their method of inflation.The uilleann pipes are distinguished from many other forms of bagpipes by their sweet tone and wide range of notes together with the unique blend of chanter, drones, and regulators. The bag of the uilleann pipes is inflated by means of a small set of bellows strapped around the waist and the right arm. The bellows not only relieve the player from the effort needed to blow into a bag to maintain pressure, they also allow relatively dry air to power the reeds, reducing the adverse effects of moisture on tuning and longevity.The chanter is the part of the instrument that plays the melody. It's somewhat like a low whistle except it is not placed in the mouth. Air is pumped through the bellows which is attached to the player's right elbow, hence the name. To achieve the â€Å"bottom D† the chanter is lifted off the knee, exposing the exit of the chanter's bore, where the note is produced. The chanter is set on the right knee thus closing off the bottom hole. Many players use a strip of leather placed over the knee, called a â€Å"popping strap,† which provides for an airtight seal.A great range of different timbres can be achieved by varying the fingering of notes and also raising the chanter off the knee, which gives the uilleann pipes a degree of dynamic range not found in other fo rms of bagpipes. A type of simultaneous vibrato and tremolo can be achieved by tapping a finger below the open note hole on the chanter. The bottom note also has two different â€Å"modes†, namely the â€Å"soft D† and the â€Å"hard D†. The hard bottom D sounds louder and more strident than the soft D and is accomplished by applying slightly more pressure to the bag and flicking a higher note finger as it is sounded.Many chanters are fitted with keys to allow accurate playing of all the semitones of the scale. Most uilleann chanters are very responsive to â€Å"half-holing† or â€Å"sliding†, which is the practice of obtaining a note by leaving a fingerhole only half covered. This is why many chanters sold in Ireland are sold without keys. The chanter uses a double reed similar to that of the oboe and bassoon. The regulators are equipped with closed keys which can be opened by the piper's wrist action enabling the piper to play simple chords, givi ng a rhythmic and harmonic accompaniment as needed. History The uilleann pipes developed around the beginning of the 18th century, the history of which is here depicted in prints of carvings and pictures from contemporary sources. The earliest surviving sets of uilleann pipes date from the second half of the 18th century but it must be said that datings are not definitive. Many of the early players in Ireland were Protestant, possibly the best known being the mid-18th century piper Jackson from Co Limerick. The pipes were certainly frequently used by the Protestant clergy who employed them as an alternative to the church organ.Tuning The instrument most typically is tuned in the key of D, although â€Å"flat† sets do exist in other keys. These terms only began to be used in the 1970s, when pipemakers began to receive requests for pipes that would be in tune with Generation tin whistles which are stamped with the key they play in: C, B? , etc. The chanter length determines the overall tuning; accompanying pieces of the instrument, such as drones and regulators, are tuned to the same key as the chanter.The D pipes are most commonly used in ensembles, while the flat-pitched pipes are more often used for solo playing. It is noteworthy that Irish music was predominately solo music until the late 19th century, when these fixed-pitch instruments began to play more of a role. Performers Davey Spillane of Moving Hearts has also recorded solo albums. Liam Og O Floinn of Planxty has also featured as soloist with Shaun Davey in The Brendan Voyage and with RTE orchestras. Paddy Maloney is with The Chieftains. Others from past and present include Seamus Ennis, Paddy Glackin and Paddy Keenan.
