Visual Literacy in Business - Essay Example I suggest that a committee be formed incorporating members from all departments of the company, from the senior management staff and supervisory staff, to the auxiliary staff. It has been my experience that joint efforts between departments smoothens any activity and reduces red tape and bureaucracy. In addition, a well-organized team with the support of the management is bound to succeed. However, there is need to ensure that there is an open line of communication with the C.D.C to ensure their quick response in case of an emergency. The team tasked with the disaster preparedness plan will ensure that relevant employee information such as their emergency contact lists, their next of kin and their locations are updated. By liaising with the C.D.C, the company will have access to information regarding treatment matters, at risk/infected personnel and quarantine procedures. I would also recommend simulation exercises to ensure that all company employees are well-versed with the company’s protocols in case of an outbreak or any another disaster. Howells argues that the use of visual evidence elicits emotional response from the audience. Therefore, by using visuals I think the company employees and the top management staff will be more convinced of the urgency to develop a disaster management plan. Images of the Ebola epidemic earlier this year, the symptoms and the mass graves in Sierra Leone and Liberia, will be instrumental in swaying the management and staff to act. The images will serve as a cautionary tale of how the lack of a preparedness plan, such as was the case in West Africa, can lead to the death of thousands of civilians. Visual emphasis should be placed on the adverse effects of the epidemic (Howells,

Discipline and Improve Students Behaviour in Classroom Education Essay Example for Free

Discipline and Improve Students Behaviour in Classroom Education Essay The problem of how best to discipline and improve students’ behaviour in classroom is of permanent interest. This review is oriented to searching different methodologies concerning students’ behaviour in classrooms, teachers’ discipline strategies and behavioural management. Different points of view and different examples for appropriate behaviour have been discussed referring to the topic. The sources reviewed present different solutions. This paper examines also the classroom environment and its relation to successful behaviour implementation. The first paragraphs give different definitions conversant with behaviour and discipline according to the authors’ view. The continuation of the literature review is presented by different approaches and strategies concerning a good behavioural management. This elaboration sets out some of the arguments and recommendations which are discussed in more detail. Charles C. M. submits several definitions corresponding to behaviour: Behaviour refers to everything that people do. Misbehaviour is behaviour that is not appropriate to the setting or situation in which it occurs. Discipline†¦ are strategies, procedures, and structures that teachers use to support a positive learning environment. Behaviour management is a science that puts an accent on what teachers have to do to prevent misbehaviour (Charles 1). Students’ behaviour depends on several factors such as traditions, demographic settings, economic resources, family, experiences, and more. Some authors have made important contributions in managing classroom discipline related the twentieth century. Jacob Kounin (1971), one of them, reports that appropriate student behaviour can be maintained through classroom organization, lesson management, and approach to individual students. Rudolf Dreikurs (1972) on the other hand emphasizes the desire to belong as a primary need of students in school. He identifies types of misbehaviour and gives ideas about how to make students feel a part of the class or group (p. 63). William Glasser (1986) shows another view, making a case that the behaviour of someone else cannot be controlled. He reckons that everybody can only control his own behaviour. Personally I support this idea that we must control ourselves. According to the opinion of the other authors, Linda Albert’s, Barbara Coloroso’s, Nelson and Lott’s a good discipline in the classroom can be achieved through Belonging, Cooperation, and Self-Control. A similar idea of classroom management is also presented by Rackel C. F who declares that the teachers, considered it was necessary, â€Å"to develop students’ sense of belonging to the school† (p. 1071) The author supports the opinion of the significance of a good school climate and tells that it might be precondition for facilitating positive youth development (Rackel C. F 1071). In order to attain to a good classroom atmosphere there is a need of growing positive relationship between students and teachers, motivation the students’ participation and clear rules to control classroom discipline (Rackel C. F 1072). In addition these above-mentioned views can be defined as a positive outlook as regards to improving the classroom management. Another point of view inside the subject of managing discipline is through active student involvement and through pragmatic Classroom management (Charles, C. M. 2007, p. 7). Discipline through raising student responsibility is also positively oriented approach for classroom management. The three principles that improve behaviour presented in the article â€Å"Self-assessment of understanding† are positivity, choice, and reflection (Charles, C. M. 12). There the author explains the principles meaning. He states that being positive means being a motivator. When students have opportunity to share their choices they can present themselves with a good behaviour. â€Å"Asking students questions that encourage them to reflect on their behaviour can help them to change behaviour† (Charles 14). Rebecca Giallo and Emma Little (2003, p. 22) from RMIT University Australia give their comments also on classroom behaviour management. They claim that confidence is one of the most important characteristic that influence teachers’ effectiveness in classroom management. Giallo and Little (2003, 22) based on the previous statement of Evans Tribble accept that less confident teachers seem more vulnerable to stressful classrooms. They maintain the theory that the classroom stress is a reason for giving up a teacher’s career. In school the stress can be overcome through involving of drastic measures concerning managing a good discipline. One of the most popular strategy for solving behaviour problems is punishment. By reason of the popularity of the subject in the field of education, many experts have written articles and books as well as given lectures on discipline and punishment. Anne Catey based on Dreikur’s words considers that there is no need of using punishment in class. Based on Catey’s words kids need to have a chance they can share their ideas in the class (1). This is the best way to â€Å"smooth, productive functioning in schools† (Charles, C. M, 1999). Anne Catey from Cumberland High School gets an interview from several teachers in Illinois district about their discipline practices. She accepts the suggestion given by Lawrence as mentioning that, â€Å"very effective technique is a brief conference, either in the hallway or after class, with the misbehaving student† (Punishment, 1). Anne Catey has her own techniques for classroom management. She disagrees with Lawrence viewing about humour as one of the bad strategies for effective discipline and believes that using of humour can be effective if done without abasing the students (Punishment, 1). In this way she gives each one a bit of individual attention. When some of her students are a bit distracted on one task, talking to friends instead of reading Catey says, â€Å"Since I always assume the best of my students, I assume the noise I hear is students reading aloud or discussing their novels. However, it’s time to read silently now instead of reading aloud† (Punishment, 1). This sounds as a good strategy but personally I disclaim this thesis. This doesn’t work all the time. I am trying to be strict with my students and according to this the pupils have to observe the rules in my classes. That doesn’t mean that I admit the severe punishment but rarely the stern warnings. I agree with the following techniques used by Anne Catey (2001) to modify behaviour including giving â€Å"zeroes for incomplete, inappropriate, and/or missing work and taking points off at the end of a quarter for lack of participation and/or poor listening†. As expected, these methods are effective for some of the pupils but not for the others. Related to the above-mentioned topic it could be noticed some of the classroom discipline strategies utilized in Australia, China and Israel. On the basis of elaborated research in these countries some psychologists and school principals (Xing Qui, Shlomo Romi, 2005) conclude that Chinese teachers appear less punitive and aggressive than do those in Israel or Australia. Australian classrooms are presented as having least discussion and recognition and most punishment. In Australia (Lewis, 2005) as concerned to the study the teachers are characterized by two distinct discipline styles. The first of these is called â€Å"Coercive† discipline and comprises punishment and aggression (yelling in anger, sarcasm group punishments,  etc). The second style, comprising discussion, hints, recognition, involvement and Punishment, is called â€Å"Relationship based discipline† (Lewis 7). Coercive discipline according to the above-mentioned authors means the teacher’s behaviour is such as â€Å"shouting all the time, unfairly blaming students, picking on kids, and being rude, to stimulate student resistance and subsequent misbehaviour† (Lewis, Ramon 2). The importance of classroom discipline arises not only from students’ behaviour and learning as outlined above. It depends also on the role of the teacher. Sometimes it is obvious that teachers are not be able to manage students’ classroom discipline and it can result in stress. So,â€Å"classroom discipline is a cohesion of teacher stress† (Lewis 3). Chan (1998), reports on the stressors of over 400 teachers in Hong Kong, claims that student behaviour management rates as the second most significant factor stressing teachers. In the article Teachers’ Classroom discipline several strategies have been presented for improving classroom management. They are Punishing (move students’ seats, detention), Rewarding (rewards, praises), Involvement in decision-making (decides with the class what should happen to students who misbehave), Hinting, Discussion and Aggression. Another strategy for improving discipline in class is conducting questionnaires between the students. It is an appropriate approach for defining students’ opinion about behaviour problems. In each Chinese and Israeli school a random sample of classes at all year levels have been selected. As a research assistant administered questionnaires to these classes their teachers completed their questionnaires (Yakov J. Katz 7). In comparison to all of the mentioned countries the model in China is a little different in that students support use of all strategies except Aggression and Punishment. Based on the conducted research the only strategy to range within a country by more than 2 ranks is Punishment, which ranks as the most common strategy in Australia, and the fourth and fifth most commonly used strategy in Israel and China. The author, Xing Qui generalises that, â€Å"there is not more Punishment at the level 7-12. â€Å"Classroom discipline techniques showed that students in China, compared to those in Australia or Israel, report less usage of Punishment and Aggression and greater use of Discussion and the other positive strategies. At the end of their article â€Å"Teachers’ classroom discipline and Student Misbehaviour in Australia, China and Israel â€Å"(p. 14) the authors recommend that teachers need to work harder to gain quality relationships with difficult students. What I have drawn from reviewing literature so far is that teachers are able to use different techniques for enhancing classroom management in their profession. After making a thorough survey on the above-mentioned issue I would like calmly to express my position. It is harder for the teacher to keep the student focused on any frontal instruction. That’s why as with all classroom management practices, the teachers should adapt what they like to their classroom, taking into consideration the age, ethnicity, and personality of the class as a group, and of them as teachers. Much of the disruptive behaviour in the classroom can be alleviated before they become serious discipline problems. Such behaviours can be reduced by the teacher’s ability to employ effective organizational practices. These skills are individual for each teacher. The lecturer should become familiar with school policies concerning acceptable student behaviour and disciplinary procedures. Establishing rules to guide the behaviour of students is also important. Once these standards are set up the teachers have to stick to them. I agree with the authors who prefer involving the positive approach in behaviour management. But I also accept that some situations are more complicated than the others and in this case the teachers must take drastic measures against inappropriate students’ behaviour.

Senate Essay -- American History, The Confederation Congress

The Confederation Congress was plagued with problems, as the former colonies struggled to form a national identity. The lack of permanent physical location and united national government, led to problems of inaction, following the Revolutionary war. â€Å"Congress’s lack of power and frequent inability to act (often due to a lack of quorum or the need for a supermajority for certain decisions) demanded reform† (Wirls, p. 58). The founders agreed on the need for reform, opposing groups argued about the nature. Federalists argued for a strong national government, with few representatives, removed the day to day local political affairs. They desired a group of political elites, free to make decisions based on national interests. In order to promote an independent nature within the senate, Federalists advocated long terms, some advocating lifetime appointments. The anti-Federalists rejected the idea of permanent elite, instead promoting large numbers of repre sentatives, with small groups of political constituents. Rather than the crà ¨me de la crà ¨me of society, anti-Federalists envisioned a kaleidoscope; representatives would personally reflect the interests of constituents. During the final constitutional plan for the U.S. Senate, a compromise was reached; anti-Federalist views were incorporated through the equal apportionment and appointment by states, Federalists insured independence in the senate by instituting staggered six year terms. Compromise between the Federalist and anti-Federalist was reached through a series of decisions, in no small part assisted by the fact that those against strengthening the Federal government were not present, â€Å"the formidable talents who were opposed to the project of fortifying the... ...emate concerning the national congress. With the rights of small states protected through equal representation in the senate, the convention was able to move forward in forming a strong national government with responsibilities and rights separate from the states. Federalists were able to protect the independence of the senate, through staggered six year terms and more stringent eligibility requirements than those for the House of Representatives. The eventual formation of a separate national capital insured the both physically as well as psychologically desired independence of the senate and congress. The members of both sides present shared a mutual understanding of the need for a senate in a stronger national system. The decisions which lead to the compromise resulted in the creation of a senate which included both Federalist and anti-Federalist views.

My role involves making sure that our clients are provided with adequate care and support.It is important to understand the limits of the role and seek assistance t o deal with issues which are beyond the scope of social care, and liaise with other agencies to provide seamless care such as arranging and attending appointments, carrying out treatment, and therapy regimes.3.4 Describe the main roles and responsibilities of representative bodies that influence the wider sector. The main bodies that influence the Health and Social Care sector are government departments, professional bodies, trade unions, various skills councils and regulatory bodies.The main roles and responsibilities of the government departments are a duty to promote the economic, social and environmental wellbeing of their communities. The professional bodies have a number of functions. They may set and assess professional examinations, provide support for Continuing Professional Development through learning opportunities and tools for recording and planning, publish professional journals or magazines, provide networks for professionals to meet and discuss their field of experti se, issue a Code of Conduct to guide professional behaviour, deal with complaints against professionals and implement disciplinary procedures.The representative bodies such as trade unions play an important role and are helpful in effective communication between the workers and the management. They provide the advice and support to ensure that the differences of opinion do not turn into major conflicts. The central function of a trade union is to represent people at work. But they also have a wider role in protecting their interests.The sector skills councils create the conditions for increased employer investment in skills which will drive enterprise and create jobs and sustainable economic growth. The regulatory bodies exercise a regulatory function: impose requirements, restrictions and conditions, set standards in relation to any activity, and secure compliance & enforcement. 4. Understand career pathways available within own and related sectors 4. 1 Explore different types of o ccupational opportunities.There are different pathways available within Health and Social Care sector, including: Adult Social Care, Healthcare: Arts Therapy, Clinical Support Staff/Healthcare Assistant, Dentistry & Dental Hygiene, Medical Doctors & Surgeons, Medical Sales & Marketing, Nursing & Midwifery, Paramedic & Ambulance Services, Physiotherapy, Rehabilitation & Occupational Therapy, Psychological Therapy, Speech & Language Therapy; Social Care: Adoption & Fostering, Alcohol & Substance Misuse, Children & Families, Domestic violence, Housing & Homelessness, Learning Disabilities, Mental Health, Older People, Physical & Sensory Impairment, Sexual Health, Social Work, Youth Work & Youth Justice.4. 2 Identify sources of information related to a chosen career pathway.

Myself and my colleagues have been made aware of these areas and solutions to possible difficulties by received regular training on these issues.

Critical Care Sound Environments Health And Social Care Essay

ABSTRACT. Intensive attention units in infirmaries take attention of critically sick patients under really nerve-racking conditions. A turning literature is demoing that intensive attention units ( ICUs ) are frequently really noisy and frequently transcending World Health Organization ( WHO ) guidelines1,2. However few surveies have linked more elaborate analyses of the sound environment, such as mean sound force per unit area degrees, transient sound degrees, and spectral distribution, to nurse well-being and public presentation. This survey differs from old surveies in several ways. Namely, we have studied the possible impact of layout design applications on the features of ICU sound environments. This was accomplished by comparing the subjective and nonsubjective qualities of two ICU sound environments with different layout designs. Furthermore, the survey included: 1 ) detailed nonsubjective and subjective noise degree measurings at multiple locations in each of the two units st udied, and 2 ) analysis of the association between the aim and subjective noise degrees via different statistical trials, including analysis of the impact of the ICU sound environments on sensed nurse results.I. IntroductionThe sound environments of ICUs are aurally demanding while nurses endeavor to put to death complex undertakings. It hence becomes of import to understand the acceptable and unacceptable subjective and nonsubjective qualities of the ICU sound environments from the nurses` point of position. In this survey, we believe nurses ‘ perceptual experience of their workplace sound environment is critical for the rating of undertaking and nurse well-being supportive ICU sound environments. By matching the subjective perceptual experience measurings with nonsubjective sound degree measurings, we can derive a more thorough appreciation of how physical and perceptual acoustic parametric quantities interact in the ICU scene. In order to cast visible radiation on these con cerns, we focused on the undermentioned research inquiries in this comparative research survey: 1 ) Do nonsubjective noise degrees differ: ( a ) between assorted locations within an single critical attention unit? ( B ) when comparing similar locations in the two critical attention units to each other? ( degree Celsius ) when comparing overall ( mean ) degrees in the two critical attention units to each other? ; 2 ) Do nurses` noise-induced irritation and loudness perceptual experience differ: ( a ) between assorted locations within an single critical attention unit? ( B ) when comparing similar locations in the two critical attention units to each other? ; 3 ) Does the sensed impact of overall noise degrees in the workplace on subjective nurse wellbeing and work public presentation differ when comparing two units to each other? ; 4 ) Is there a relationship between aim and subjective noise degrees? ; 5 ) Is there a relationship between noise degrees and noise-induced nurse results? II. PREVIOUS RESEARCHA. Overview of Hospital Acousticss1. ResultsThe acoustic environment in infirmaries can impact all residents, including staff, patients, and visitants. The undermentioned treatment in relation to the focal point of this survey is largely limited to the effects of noise on staff members: emphasis and irritation ; work public presentation ; wellness results and work overload. Information about how hospital acoustics may impact patients and visitants can be found in beginnings such as Bush-Vishniac et Al. 2 and Ryherd et al.3. The staff ‘s well-being, efficiency and effectivity in presenting attention and executing critical undertakings is critical to maximise patient safety, satisfaction, and attention quality in ICUs. Stress-annoyance: Intensive care unit are nerve-racking attention scenes that can be exacerbated by the centripetal overload caused by environmental factors, including the acoustic environment. Stress is the person ‘s assessment of a mis match between perceived demand and perceived self-capabilities to get by 4. Depending on the badness and continuance, it may take to illness ( i.e. , elevated blood force per unit area, dyspepsia ) , behavioural alterations ( i.e, unhappiness, depression, negative attitudes ) . Anxiety is a psychological responses to environmental stimulations or activity bring forthing rousing 5. Excessive anxiousness degrees can take to upsets. Like anxiousness, irritation is one of the early psychological responses which reflects the unwantedness of the environment stimuli 6. Irritation relates to the invasion of a stimulation on a mental or physical activity. In one survey, higher mean sound force per unit area degrees predicted higher sensed emphasis, and perceived irritation degrees in a Pediatric-ICU 7. In another survey, less sensitiveness to resound and greater personality robustness ( such as committedness, control, and challenge ) were linked with less noise-induced emphasis 8. In the same survey, ICUs nurses working eight-hour eventide displacements reported that they were significantly distressed by noise. There is some grounds that high noise degrees in attention scenes contribute to staff emphasis and irritation. However, the figure of noise-induced nurse emphasis surveies conducted in the ICUs is really limited. Work public presentation: Hospital sound environments that are supportive of infirmary undertakings could potentially better staff effectivity in presenting attention. Improved nurse work public presentation in ICUs can forestall inauspicious events, better health care quality, and optimise resource use. The survey fou nd that noise in the workplace was perceived to hold a negative impact on staff work public presentation and concentration 3. A Neonatal-ICU survey showed that sound that exceeds 55dBA most of the clip can potentially interfere with work. This multidisciplinary literature reappraisal survey highlighted that undertakings necessitating rapid reaction clip and watchfulness are sensitive to resound. Noise-induced work public presentation research has been more normally conducted in the operating theatres 9-11. The impact of noise on staff public presentation ( particularly in ICUs ) has non been widely examined. Health results: The acoustic environment throughout the infirmary may lend to negative ague or chronic symptoms in staff. Critical attention nursing is a really demanding occupation and it requires uninterrupted watchfulness, watchfulness, and wellbeing to carry on critical undertakings efficaciously. The survey found that of the 47 ICU nurses surveyed in an ICU, reported annoya nce, weariness and concerns due to workplace noise 3. The earlier mentioned survey besides showed that addition in mean sound degrees was significantly related to an addition in bosom rate 7. Elevated bosom rate can tie in with cardiovascular harm particularly in hypertensive persons 12. Noise-induced hearing loss has been the concern for executing sawboness in the operating theatres 13,14. However, noise-induced wellness results ( including hearing loss ) of ICU nurses` have non yet been the focal point of hospital noise literature. Work overload: Work overload can be critically of import for overall wellbeing of staff. Poor acoustical conditions in workplaces can worsen staff attitude and perceived work overload. When noise degrees exceed a nurse ‘s get bying abilities it can take to centripetal overload 6. Centripetal overload can do emotional exhaustion, dissatisfaction, and decreased sense of personal achievement. This in bend can do feelings of ineffectualness, awkwardne ss, low satisfaction, and perceived deficiency of success 15. In one survey, it was found that medicine mistake and other inauspicious events necessary for patient safety were associated with emotional exhaustion and staff burnout 16. In another survey it was besides found that nurse emphasis due to ICU noise was positively related to nurse emotional exhaustion and burnout17. Hagerman et Al. showed that in a coronary bosom unit enhanced acoustical conditions such as decreased echo clip and improved address intelligibility improved staff attitude perceived by patients 18. The limited bing grounds points to a important job that should be investigated farther to find appropriate acoustic conditions that will minimise negative work overload effects.2. Acoustic prosodiesThere is a turning organic structure of literature on infirmary noise. Many of those surveies focus on qualifying overall noise degrees in a assortment of hospital infinites including ICU ‘s, but few of them focuses specifically on ICU staff response 3. A assortment of different methods have been used in qualifying the infirmary sound environment. The grounds of these methodological analysis differences are non good known 3 but may be related to motivations such as single penchants, practicality, common sense, convenience, the degree of proficient expertness, etc. ( 1 ) Overall noise degree steps: These steps have been preferred most normally. This may be based on their practicality and convenience, in add-on to their incorporation into assorted guidelines such as WHO. Leq, Lmin, Lmax and Lpeak sound degrees can supply a general overview of the sound environment, but they remain limited for the elaborate analysis of the sound environment. ( a ) Leq: It enables the speedy comparing of the noise degrees with recommended values and those in other types of infinites. Therefore, it might be widely accepted as to be the primary step to depict a sound environment. This might besides happen in relatio n to the degree of proficient expertness required to show some penetration about more elaborate features of the sound environment. However, this common belief can be misdirecting about the truth and adequateness of the usage of chiefly Leq degrees. ( B ) Lmax, Lpeak and Lmin: The highest and the lowest values measured over clip provide more information about the overall noise degree fluctuations. In most instances, these steps are conventionally used to depict infirmary sound environments. However, these values remain unidimensional and level to depict the general tendency in sound environment. ( 2 ) Detailed noise degree steps: To counterbalance the restrictions of the overall sound steps, the usage of extra acoustic prosodies is critical for the elaborate analysis of the sound environment. Compared to above mentioned sound steps, Ln percentile ( Ln ) , echo clip ( RT ) , speech intelligibility ( SI ) , and the spectral content such as frequence analysis and noise standards steps h ave been less normally used. Hospital acoustic research has been the involvement of different research groups such as medical groups and proficient groups. Based on the group ‘s proficient expertness on the subject, some acoustic prosodies might hold been preferred to the others. ( a ) Sound quality related steps: In the ICUs, there is diverseness of noise beginnings such as dismaies, HVAC systems, conversation and medical equipment. Those noise beginnings generate noises with different frequences and sound forms. Ln percentiles and spectral content analysis become of import for elaborate analysis of fluctuations, tonic content, spectral distribution, and other features in the noise degrees over clip. ( B ) Speech quality related steps: Some other specific features of the infirmary room acoustic environment have been described with the usage of extra acoustic prosodies such as SI and RT. To construe the intervention of the infirmary noise degrees and room conditions with criti cal medical communications, SI has been used. To stand for the degree of drawn-out being of noises that can perchance overlap and interfere or dissemble the other sounds, RT has been used.3. Measuring ICU sound environmentsMethods applied during the sound sample aggregations can hold important impact on the appraisal of the infirmary sound environments. There has non been a widely accepted understanding about how the sound samples should be collected to qualify the complex and dynamic ICU sound environments in close propinquity to occupant experience 3. However there has been some consensus on a few methodological considerations among different ICU-noise surveies such as locations where sound informations collected in the attention scenes. Noise degrees in the ICU patient suites have been normally documented. Sound recordings took topographic point either in a representative patient room 3,19,20 or in more than one patient room with different characteristics such as distance to the nurse station, occupied-empty, figure of patient beds 2,7,21-28. There was a good understanding on the location of the sound metre: every bit near as possible to patient caput – to capture what the patient hears- while avoiding any intervention with nurse work flow. Hanging the mike from the top of the medical tower in the patient room has been introduced as a practical solution 3. Different continuances were preferred for the aggregation of sound samples such as 168hr, 72hr, 24hr, and 8hr at patient locations. Among those, 24hr entering period was more widely accepted than others. A few ICU-noise surveies have conducted different continuance noise degree measurings at the nurse Stationss such as 24hr and 168hr 2,26,27. Busch-Vishniac et Al. described the sound environment of one more puting – hallways- in their survey and placed the metre at the room centre 2. Largely the merchandises of two companies have been preferred to mensurate sound degrees: Larson Davis and Br uel & A ; Kj?r. It was non a common attack to document the sound metre scenes used. Much of the noise degree measurings were conducted based on slow response clip ( 1sec ) as suggested by Occupational Safety and Health ( OSHA ) for typical occupational noise measurings 2,28,29. Some surveies used fast response clip ( 0.125sec ) as suggested by WHO 3,21. When recorded based on fast response clip, more fluctuations can be expected in the sound degrees. The penchants among averaging intervals varied and ranged between 5sec and 24hr ( i.e. 30sec, 1min, 5minaˆÂ ¦etc. ) . Among ICU-noise surveies the usage of 1min averaging interval was more common likely because it enables a more elaborate expression to the clip history informations. Sound recordings were normally analyzed as a map of clip. Day clip and dark clip mean sound degrees were normally reported. Among the reviewed ICU-noise surveies, non many of them were conducted during the weekends but during the weekdays. Morrison et A l. and Ryherd et Al. considered twenty-four hours and dark clip based on 12s hr nurse displacements ( twenty-four hours time:7am-7pm ; dark clip: 7pm-7am ) 3,7. MacKenzie and Galbrun considered the twenty-four hours and dark clip periods based on WHO guidelines ( 16hour twenty-four hours time:7am-11pm ; 8hr dark time:11pm-7am ) 21. In drumhead, consistence of the methodological penchants in infirmary acoustics research can be really helpful for the dependability of the comparings between the consequences of different surveies.III. METHODOLOGYPutingThe research was conducted in two intensive attention units ( ICU ) at Emory University Hospital. Neurological ICU ( Neuro-ICU ) is a late opened 20- bed unit ( Fig. 2 ) . This unit received the â€Å" ICU Design Citation † award in 2008 for its design purpose to heighten the critical attention environment for patients, households and clinicians. Some unit design features include big private patient suites with household studio, dis trusted nurse work countries and care support countries and a scope of noise cut downing applications. High public presentation absorbent acoustic ceiling tiles and bead ceiling applications reside chiefly along the two parallel sides of the corridors and at the nurse Stationss, painted dry wall, vinyl flooring and 6ft broad ( two-wing ) glass patient room doors are some of the surface applications in the unit. Patient attention nucleus of the Neuro-ICU sits about on 19,000sqft. This nursing floor has a bunch type layout. The layout is composed of a six- bed and fourteen- bed bunchs. Each bunch has a cardinal nurse station with its ain attention support countries ( e.g. medicine room, supply roomaˆÂ ¦etc ) and computerized patient monitoring system. In entire, the unit has two cardinal nurse Stationss and 17 distributed nurse work countries. Approximately one-third of the 390sqft patient room is segregated from the patient attention country by a semi-opaque glass wall and good equipped for household demands. Approximately one-third of the patient attention nucleus floor country is occupied by the corridors. The length of the corridors is 600ft. Entire Neuro-ICU includes extra infinites such as public household countries, CT scan lab, and a curative garden. With all these infinites, the entire Neuro-ICU sits about on 24,000sqft. The Medical Surgical ICU ( MedSurg-ICU ) is a 1980s epoch twenty-bed unit ( Fig. 1 ) . Compared to the other unit, MedSurg-ICU has a more traditional physical environment with ceiling tile, vinyl flooring, 5ft broad ( two-wing ) glass patient door and painted dry wall surface applications. Patient attention nucleus of this unit sits about on 8,800sqft. The nursing floor has a triangular form race path layout design – medical and support countries are located in the centre and patient suites are located on the margin and the corridor separates these two infinite types. Twenty private patient suites are organized around one big triangular form service hub. This hub contains two patient monitoring cores – each serves to ten patients- at the corners and a centralised attention support country. Patient suites in this unit are about 190sqft and equipped with a Television like the patient suites in the other unit. This peculiar layout type requires the usage of unintegrated co rridors for staff and household members. Approximately, one-quarter of the patient attention nucleus floor country is occupied by the staff corridor. The length of the staff corridor is 240ft. Entire MedSurg ICU including the household corridor environing the unit, sits about on 12,500sqft. In contrast to the physical environment differences, both units apply similar staffing theoretical accounts with intensivists and nurse practicians and suit critical attention patients with similar sharp-sightedness degrees. In both units, by and large ten to twelve registered nurses are working during each displacement. The Neuro-ICU nurses largely work 12-hr displacements ( 7am-7pm, 7pm-7am ) ; the MedSurg-ICU nurses besides work 8-hr displacements ( 7am-3pm, 3pm-11pm, and 11pm-7am ) . In both units, nurses can work either at the weekend or during the weekdays or both ; during the twenty-four hours clip or dark clip or both.Measures1. SoundObjective and subjective noise degree measurings in two units were conducted during two back-to-back months. In both units, same processs were applied. Objective noise degree measurings were conducted at four different locations in each unit: centralised nurse station, empty patient room, occupied patient suites with and without respiratory venti lator and multiple informations points in the corridors. A sum of 96-hr uninterrupted stationary noise degree measuring was conducted at the nurse station of each unit from Thursday to Monday. Saturday and Sunday was deliberately included as it has non been much addressed in the literature. In each unit, 24-hr uninterrupted stationary sound degree measurings were conducted in the occupied patient suites without respiratory ventilator during a weekday. In relation to limited entree, merely 45-min sound samples were collected from the occupied patient suites with respiratory ventilator. Similarly in each unit, 45-min uninterrupted stationary sound degree measuring was conducted an empty patient room while patient room doors were closed. At the corridors, multiple 15-min sound samples were collected at indiscriminately selected times during twenty-four hours and dark. In entire, about 246-hr sound informations was collected from both units. For the computation of overall noise degrees in each unit, all sound informations collected at different locations were taken into consideration. Medical equipment dismaies happening in the patient suites, patient proctor dismaies happening both in the patient suites and at the nurse Stationss, sound of the ice machine engine, phone ring, staff conversation, turn overing medical carts in the corridors were some of the common noises in two units. In MedSurg-ICU nurses are paged via overhead beepers. In Neuro-ICU 3G-phones or regular phones at the baies are used alternatively. At the corridors, the mike was located at a tallness of 4.5ft somewhat off the room centre and stabilized on a tripod. In the patient room, the mike was hanged from the ceiling at a tallness of 6ft. The distance between the patient ‘s caput and the mike was minimized every bit much as possible. Similarly, mike was hanged from the ceiling at the nurse station at a tallness of 6ft. In Neuro-ICU, the sound metre was set up at the nurse station of fourteen-bed side. In MedSurg-ICU, sound metre was located at somewhat off the centre of the cardinal nurse work zone in the centre of the unit. Sound information was collected utilizing a fast response clip for upper limit and lower limit degrees ( 0.125 s ) as recommended by World Health Organization ( Berglund and Lindvall 1999 ) . Three Larson Davis-type 824 sound degree metres were used and collected informations was downloaded via Larson Davis 824 Utility package. For unattended field measurings, two Lockable Larson Davis outdoor me asurement instances were used. . For safety intents, 50ft mike extension overseas telegram was run from each outdoor sound metre instance to the walls and eventually to the mark point on the ceiling. The out-of-door noise measuring instance was placed carefully at a topographic point out of the nurse manner. Before any installing effort, proposed locations for the arrangement of sound metre at different locations in the units were approved by the charge nurse. One-minute averaging interval was used. One-third octave set informations was obtained. The dynamic scope was 80dB un-weighted from floor-38dB to overload-118dB.2. Self-reportAn electronic study was administered to 90 and 60 five registered nurses working in Neuro-ICU and MedSurg-ICU severally. Nurses were contacted via electronic mail by the nurse pedagogue of each unit and they gave their consents online. The study consisted of four subdivisions: nurse profile and working conditions, perceived sound environment in the workpl ace, perceived impact of noise degrees on nurse results, general hearing wellness and noise sensitiveness. Survey response rate was 39 % and 35 % in Neuro-ICU and MedSurg-ICU severally. In Neuro-ICU, 85 % of the nurses participated in the survey was full clip and 15 % was portion clip nurses. In MedSurg-ICU, 70 % of the nurses participated in the survey was full clip ; 26 % was portion clip and the remainder was PRN. In two units more than 80 % of the nurse population was female. Similarly, in both units more than 80 % of the nurses were younger than fifty old ages old.IV. ResultA. Objective noise degrees1. Make nonsubjective noise degrees differ when comparing overall ( mean ) degrees in the two critical attention units to each other?Noise degrees measured at multiple different locations in each unit are averaged for the computation overall noise degrees including Leq ( assumed name ) , Lmax ( dubnium ) , Lpeak ( dBC ) and Lmin ( dubnium ) . Those locations are: nurse station empty patient room, corridors and occupied patient suites with and without the respiratory ventilator. To clear up, in order to spread out the sample size, measurings conducted in the occupied patient room with ventilator were besides considered in the computation of overall noise degrees for each unit. In MedSurg ICU and Neuro-ICU overall averaged Leq, LMax, LMin and LPeak noise degrees ranged between 57-58dBA, 105-97dB, 57.5-54dB, and 120-113dBC severally. Detailed consequences are shown in Fig. 2. For elucidation intents, in this paper the term â€Å" averaged † does non reflect the calculation methods used but refers to the consideration of multiple measurings in the computation of individual noise degree. More elaborate analysis consequences are shown in Fig. 3. This chart represents the per centum of clip that different degree unprompted sounds ( LFMax ) in the scenes exceeded peculiar noise degrees. This type analysis consequences are referred as â€Å" happening rate â₠¬  in this paper. In both units more than 98 % of the clip LMax noise degrees exceeded 70dB. It was more than 96 % of clip that LPeak noise degrees exceeded 80dBC in both units. Finally, it is possible to reason, the difference between overall averaged LAeq degrees in Neuro-ICU and MedSurg ICU are unperceivable. Information about perceptual experience of alteration in sound intensivity can be found in Mehta et al 30. However elaborate noise degree measurings indicated significant differences. The sound environments of two units are different based on the happening rate of the impulse sounds at high noise degrees.2. Make nonsubjective noise degrees differ when comparing similar locations in the two critical attention units to each other?A-weighted mean sound force per unit area degrees ranged between 52-60dB and 45-56 dubnium at four different locations in MedSurg-ICU and Neuro-ICU severally ( Fig. 4 ) . Those four locations were nurse station, occupied patient room without respirat ory ventilator, empty patient room and the corridor. In both units, patients with respiratory failure are connected to respiratory ventilator and most of those patients are under isolation which restricts the entries and activities in the patient suites. It was possible to carry on comprehensive measurings in the patient room without respiratory ventilator. Therefore, measurings conducted in the occupied patient room without respiratory ventilator was considered for location particular more elaborate noise degree analysis. At all four locations, LMax degrees exceeded 70dB about full clip in both units. Except empty patient room, at all other locations LMax noise degrees exceeded 80dB more than 36 % of the clip In MedSurg ICU and 11 % of the clip in Neuro-ICU. In general, noise degrees and happening rate of high degree impulse sounds was higher in MedSurg-ICU. Average sound force per unit area degree ( LAeq ) differences between nurse Stationss, occupied patient suites and the corrid ors of two units were either unperceivable or merely perceptible ( Fig. 4 ) . However LAeq noise degree difference between two units` empty patient suites was significant. LMax happening rates were dramatically different from each at other locations. Happening rates occurred at the nurse Stationss are shown in Fig. 5 as an illustration. However LMax happening rates did non differ dramatically in the empty patient suites ( Fig. 6 ) . LPeak happening rate analysis showed really similar consequences to LMax happening rate consequences.3. Make nonsubjective noise degrees differ between assorted locations within an single critical attention unit?In MedSurg-ICU and Neuro-ICU, overall noise degrees and happening rates of impulse sounds was much lower in the empty patient suites compared to other locations ( Table I ) . Occurrence rate of LPeak & gt ; 90dBC was systematically higher at the nurse station compared to other locations in both units. However, noise degree differences between nur se station and other locations were non ever perceptible based on differences between A-weighted Leq degrees.B. Subjective noise degrees1. Make nurses` noise-induced irritation and loudness perceptual experience differ between assorted locations within an single critical attention unit?In MedSurg-ICU, perceived loudness degrees at the nurse station were significantly higher ( p & lt ; 0.05 higher ) than other three locations harmonizing to nonparametric significance trial consequences. Average degrees of subjective irritation and volume are shown in Table II. Similarly, in Neuro-ICU perceived volume and irritation degrees in the empty patient room were significantly less ( P & lt ; .05 ) than other three locations.2. Make nurses` noise-induced irritation and loudness perceptual experience differ when comparing similar locations in the two critical attention units to each other?At all four locations – the nurse station, in the empty and occupied patient room and at the corrido rs perceived irritation and volume degrees of MedSurg-ICU nurses were systematically higher than the sensed degrees reported by Neuro-ICU nurses ( Table II ) . MedSurg ICU nurses perceptual experience of noise-induced irritation and volume at four locations ranged between 2.25 and 4.1.Same sensed degrees ranged between 1.6 and 3.2 among Neuro-ICU nurses. Additionally, nonparametric Mann-Whitney U trial consequences showed that noise-induced irritation and loudness perceptual experiences of nurses at the nurse Stationss and in the empty patient suites was significantly different in two units. Two unit nurses` sensitiveness to resound and tolerance to high noise degrees in the workplace did non differ significantly ( p & gt ; .05 ) . Overall, nurses were non really sensitive to resound and they could digest high noise degrees slightly.3. Does the sensed impact of overall noise degrees in the workplace on subjective nurse wellbeing and work public presentation differ when comparing two units to each other?A ­Perceived negative impact of workplace noise degree on five nurse result was reported higher by MedSurg-ICU nurses compared to Neuro-ICU nurses. MedSurg-ICU and Neuro-ICU nurses` responses ranged between 3-4.3 and 1.7-3 severally ( Table III ) . Overall, MedSurg-ICU sound environment was perceived systematically worse for nurse well-being and work public presentation compared to Neuro-ICU sound environment. Harmonizing to nonparametric significance trial consequences, all perceived five noise-induced nurse results differed significantly in two units.C. Correlations1. Is at that place a relationship between aim and subjective noise degrees?Spearman nonparametric correlativity trial was used to analyse the relationship between aim and subjective noise degrees. Overall and individually analyzed MedSurg-ICU and Neuro-ICU subjective and nonsubjective noise degrees systematically represent the being of a important relationship between subjective and nonsubjective noise degrees ( Table IV ) . Subjective noise-induced irritation and volume degrees are significantly and positively correlated with A-weighted mean sound force per unit area degrees and happening rate of impulse sounds happening at high degrees.2. Is at that place a relationship between noise degrees and noise-induced nurse results?Overall, subjective volume degrees are significantly and positively correlated with sensed noise-induced irritation, work public presentation, wellness and anxiousness ( p & lt ; .01 ) .D. Spectral content1. Frequency distribution of noise degreesOverall, sound force per unit area degrees were higher in MedSurg-ICU at low, mid and high frequence scopes ( 250Hz-8kHz ) ( Fig. 7 ) . At all locations but empty patient room, noise degree differences across frequences were largely either merely perceptible or unperceivable. At 8kHz clearly noticeable noise degree differences occurred between two unit nurse Stationss and occupied patient suites. At 250Hz and 5 00Hz, clearly noticeable and significant noise degree differences occurred between empty patient suites. Below 250Hz, sound force per unit area degrees were largely higher in Neuro-ICU ( Fig. 8 ) . In the empty and occupied patient room, noise degree differences at 16Hz were significant otherwise it was either merely perceptible or clearly noticeable. This happening might be related with the busyness noise generated by the HVAC engine located in the unfastened infinite in Neuro-ICU. This unfastened infinite about located in the centre of the unit and is non accessible by the residents but included in the design to supply natural visible radiation for some patient suites.2. Room Criteria ( RC ) analysisIn MedSurg-ICU, RC values were higher. However, RC evaluations were largely hissy and vibrational in Neuro-ICU while it was chiefly impersonal and non vibrational in MedSurg-ICU ( Table V ) .E. Fluctuation clipF. Speech Interference LevelIn general, speech intervention degrees in MedSu rg-ICU were higher at all four locations analyzed compared to Neuro-ICU. At the nurse Stationss, address intervention degrees ( SIL ) of the noise were highest and ranged between 50-53dB ( Table VI ) . Two female nurses will be able to ( hardly ) communicate with each other in normal voice up to a distance of about 3-4ft. Same distance ranged between 5.5-7.5ft if nurses raise their voices. Slightly lower SIL values occurred in the occupied patient room and in the corridors. Lower SIL degrees can enable safer communications from longer distances. Furthermore, compared to females, males in general are able to pass on better at longer distances.G. HVAC background noise degreesBackground noise degrees caused by HVAC systems were calculated based on steady 15-min sound samples collected in the empty patient suites. Sound force per unit area degrees across three frequences ( 500Hz, 1000Hz, 2000Hz ) were averaged every minute. In Neuro-ICU, HVAC noise degrees in the patient room were accep table harmonizing to American Society of Heating Refrigerating and Air-Conditioning Engineers ( ASHRAE ) recommended RC values, 25-35dB in the private suites 31. In Neuro-ICU, RC values ranged between 29-31dB. In MedSurg-ICU HVAC noise degrees in the patient room were higher than ASHRAE recommended values and ranged between 37-38dB in MedSurg-ICU.V. DISCUSSIONOne of the purposes of this survey is to lend to the on-going attempts to better health care sound environments. These attempts can enable more comprehensive analysis of helter-skelter health care sound environments. The survey findings discussed in this subdivision can supply some penetration for the appraisal of the bing and development of intelligence acoustic prosodies that might be necessary for more elaborate survey of the infirmary sound environments.1. Appraisal of overall ( mean ) vs. elaborate noise degree steps and their relation to subjective noise degreesOverall nonsubjective sound environment of two units were sig nificantly different based on elaborate noise degree measurings. Happening rate analysis is referred as elaborate noise degree measuring as it reflects the behaviour of impulse sounds during every minute. Statistically important differences between subjective noise-induced nurse results and loudness perceptual experience of MedSurg-ICU and Neuro-ICU nurses were consistent with the important differences between happening rates of impulse sounds ( LFMax, LCPeak ) that occurred at high degrees. Furthermore, nonparametric correlativity coefficient trial consequences indicated the being of a important and positive relationship between perceived irritation and volume degrees and happening rates of impulse sounds. However, overall noise degree measurings ( i.e LFMax, LCPeak, LFMin, LAeq ) particularly overall mean sound force per unit area degree did non bespeak perceptible differences between the sound environment of two units. Similarly, elaborate nonsubjective noise degree measurings be sides suggested important differences when comparing similar unprompted sound environments ( i.e. nurse station, occupied patient room and corridors ) in two units. Unlike detailed measurement consequences, overall mean sound force per unit area degree differences indicated either merely perceptible or unperceivable differences between similar locations in two units.2. Appraisal of stationary vs. unprompted sound environments and their relation to subjective noise degreesLocation specific subjective noise degree analysis ( i.e. perceived noise degrees at the nurse Stationss, in the empty and occupied patient suites and corridors ) indicated that MedSurg-ICU nurses` noise-induced irritation and loudness perceptual experiences were systematically higher than Neuro-ICU nurses` perceptual experiences. Particularly, subjective irritation and volume degrees differed significantly at the nurse Stationss and in the empty patient suites of two units. Nurse Stationss have unprompted sound env ironments where major sound beginnings are medical dismaies, telephone ring, staff laugh and talkaˆÂ ¦etc. Subjective noise degree differences between two unit nurse Stationss were consistent with important differences between happening rates of impulse sounds ( LFMax, LCPeak ) at the nurse Stationss. Unlike nurse Stationss, doors closed empty patient suites have stationary sound environments where chief noise beginning was the HVAC system. This clip, subjective differences between two unit empty patient suites were consistent with important differences between A-weighted mean sound force per unit area degrees measured in the empty patient suites. Furthermore, nonparametric correlativity coefficient trial consequences indicated the being of a important and positive relationship between perceived irritation and volume degrees and mean sound force per unit area degrees.3. Fluctuation clip and subjective noise degrees4. Features of infirmary sound environments and layout design ap plicationsAbove mentioned consequences confirms the earlier findings that suggest the being of a relationship between aim and subjective noise degrees. The theoretical account reviewed here suggests that different infirmary layout design applications can chair the relationship between aim and subjective noise degrees. Two unit nurses reported sensed effectivity of different layout design applications to cut down noise degrees based on their experiences and observations. Overall, three chief layout design applications were found effectual. Those were private patient suites, segregated corridor system and a unit with baies and centralised nurse station instead than a unit with merely centralised nurse station32. Private patient suites can diminish sensed complexness of the patient room sound environment as there are less noise beginnings in single-bed suites than multi-bed suites. In MedSurg-ICU, cardinal nurse station is a common-use workplace and at most times it is extremely popula ted by nurses for coaction, single work and telecommunication intents. Higher patient bend over rates ( new admittances and conveyances ) in MedSurg-ICU besides requires extra paper work to be done at the nurse station. In Neuro-ICU, nurses largely collaborate, work separately and telecommunicate at the de-central nurse Stationss. They visit the centralised nurse station for registering patient medical records, utilizing common resources such as copy-fax machine. Segregation of corridors used by household members and staff members can command riotous breaks by household members. On the other manus, household members can get down a insouciant conversation with staff members anytime while voyaging in the shared corridors. One of the chief noise beginnings in the health care scenes are conversations. Based on researchers` observation, the physical distance between the nurse Stationss or patient monitoring nucleuss can lend to the sensed frequence of the unprompted noise happenings. In this survey noise degree and happening rate of impulse sounds found to be critical for nurses` volume and irritation perceptual experience. In MedSurg-ICU, physical distance between two patient monitoring nucleuss ( from centre to centre ) was 48ft. In Neuro-ICU, same distance between two centralised nurse Stationss was 118ft. Distribution of noise beginnings based on layout constellation can escalate complexness of the perceived sound environment33. MedSurg-ICU race path layout design offers a more compact physical environment while Neuro-ICU bunch layout design provides more broad physical environment.5. Spectral content of the sound environment vs. subjective noise degreesStatistically important subjective noise degree differences between two unit nurse Stationss were non consistent with merely perceptible differences between RC values. However, more elaborate frequence analysis showed that clearly perceptible higher noise degrees occurred at 8kHz at MedSurg-ICU nurse station. Th is happening can be related with unprompted ( high noise degrees at high frequences ) nature of sound environment at the nurse Stationss. Statistically important subjective noise degree differences between two unit empty patient suites were consistent with clearly perceptible differences between RC values. This relationship can be explained by the steady nature of the sound environment in the empty patient suites. And this happening can besides foreground the dominancy of noise degrees at mid frequences in nurses` irritation and loudness perceptual experience in steady sound environments.VI. DecisionIn healthcare acoustics literature, it is widely accepted that noise degrees in critical attention scenes are really loud and raging. This survey agrees with this decision and reminds that features of different ICU sound environments can change drastically. Some of those differences are highlighted via elaborate comparative noise degree analysis between two units in this survey. Impulsiv eness ( high happening rate at high noise degrees ) degree of an ICU sound environment is suggested to be one of the chief indexs of sensed noise-induced nurse results and nurses` volume perceptual experience. At specific locations in the unit that have with steady sound environments, higher mean sound force per unit area degrees relates better to nurse irritation and volume degrees. Spectral content of the sound environment might besides be related with nurse irritation and loudness perceptual experience. Lower perceived noise-induced work public presentation can be expected in the units with higher address intervention degrees. Furthermore noise degrees at specific locations in the unit can be acoustically more debatable than the others where focussed intercessions can be necessary. For diagnosing of these possible conditions, conductivity of elaborate noise degree measurings at multiple different locations in the unit might be of import. During and after location specific noise d egree analysis, it might be good to oppugn whether peculiar acoustic metric used represents the general feature of the sound environment studied and observed. It might be critically of import for hospital decision makers to take enterprises for cut downing unprompted noise beginnings in ICUs such as reconsideration of dismay scenes that most times do n't match to exigency degree of the incidence, integrating of higher engineering for paging health professionals such as 3G-phones and avoiding overhead beepers. It might be critical for designers to see the recent technological progresss in HVAC systems to assist bettering occupant results. The sate-of-the-art HVAC system application in Neuro-ICU offers significantly less bothersome and quieter ( clearly perceptible ) sound environment in the patient suites compared to the HVAC noise generated by the older edifice system in MedSurg-ICU. In add-on to the application of technological progresss, strategic arrangement of the HVAC engine an d its insularity from the edifice construction can be critically of import to avoid possible feelable quivers and noises happening at really low frequences. Finally, in add-on to conventional acoustic intercessions ( i.e. absorbent surface stuff applications ) , some layout design considerations can besides be critical for the formation and consideration of the health care sound environments get downing from the early design stages.RecognitionsThis work has been partly supported by ASHRAE Graduate Student Grant-In-Aid.

Night and King Lear Essays

Night and King Lear Essays Night and King Lear Essay Night and King Lear Essay Essay Topic: King Lear Twelfth Night We can tell that they are rude, impatient and demanding. They are also discriminating against the boatswain and the sailors We are merely cheated of our lives by drunkards which means that they take a fairly discriminative look on sailors as alcoholics. To the Boatswain Antonio points this abuse this wide-chappd rascal, would thou mightst lie drowning, the washing of ten tides.. The washing of ten tides refers to a punishment for pirates, which involved the eventual, slow but inevitable drowning as the sea rose to high tide. They resist the call to work. We see from their actions later on in the scene that they are also very treacherous:  Antonio: Lets all sink withking,  Sebastian: Lets take leave of him. This could be interpreted as only a very typically human action however, an action of self-preservation.  I found that Gonzalo doesnt really fulfil his role of the kings councillor, as he is actually quite an old foolish man who still tries to uphold a gentlemanly manner. This first scene shows how impotent Gonzalo is in a matter like this as he simply stands to the side and coarsely jokes to himself:  Though the ship were no stronger than a nutshell, and as leaky as an unstanched wench.  An unstanched wench is meant as a sick pun on women and menstruation. The Boatswain himself explains to Gonzalo how useless he is in the face of a natural disaster: You are a councillor; if you can command these elements to silence, and work a peace of the present, we will not hand a rope no more- use your authority. If you cannot, give thanks that you have lived so long, and make yourself ready in your cabin for the mischance of the hour, if so hap  Alonso tries to maintain an air of authority by trying to give the boatswain imposing advice such as Good boatswain, have care. Wheres the master? Play the men.  This scene carries a lot of symbolism and themes that are carried on through the rest of the play, for example the inversion of the social hierarchy as the boatswain says about the king. This is the first power struggle of the play. The boatswain makes the point that although the king has divine right, he has absolutely no power over nature, and therefore he is futile in a circumstance like this. We also see that nature or situations like the storm should and could only be resolved by those who are able to. In turn Prospero manipulates the situation, almost with a divine control, he is the only one who can put an end to the story. This is a reflection of Prosperos control over the royal party. Although they think that they have eradicated him, and are in control, like nature, Prospero has in fact got a firm grip on their lives. We can also see how helpless humans are in the face of nature. Although we like to think that we have control over it we are in fact at its mercy and in a very vulnerable position. This theme of usurpation carries on throughout the play as we see Antonio and Sebastians attempted regicide and fratricide of Alonso and Caliban, Trinculo and Stephanos parody of an assassination Prospero. In comparison to other storms in Shakespeares plays I think that The Tempest has the most dramatic impact. Superstition was a common form of belief in Shakespeares time as we can see from the witch-hunts. People would often look to the heavens to find signs, hence astrology or horoscopes and whenever a storm comes up in Shakespeare it is because there is trouble brewing or the protagonists are fighting with storm of their conscience. I looked at the storm scenes of three other plays: Macbeth, Twelfth Night and King Lear. Whenever the three witches appear on stage in Macbeth there is thunder. The three witches always cause trouble for Macbeth with their prophecies leading him to be thirstier for power. I think that the storm is installed to give an effect if mystery and menace.  In Twelfth Night we dont actually see the storm but we see that this time the storm has caused trouble. We see that emotionally the storm has initiated Violas lament for her dead brother.  The storm in King Lear makes him see what is really going on and to actually realise what the true natures of his daughters Goneril and Regan were. Thus this storm reflects his anger and realisation, his emotional struggle. However The Tempest, in my view is not used for the expression of emotion as it had been for Twelfth Night or King Lear, or to highlight bad tidings. I believe that it is an introduction, which is not to say that it means little. In fact in my view without the storm in this scene there would be little dramatic impact at all. The storm is a clever preview of what to expect from the rest of the play and it really grips your attention. I think that the storms in the other plays dont actually need to be there. The Tempest needed a natural disaster in order to reveal genuine characters and regular themes throughout the play. Without one Shakespeare would have found it difficult to stage such a dynamic introduction to his characters. The dialogue of the scene controls the tempo at which it goes. At the start of the first scene of The Tempest the pace is fast and continues to speed up until the climax at the end of the scene were we are left to wonder whether the crew and the royal party had survived or not. The immediate tone is one of urgency as the scene starts off with an imperative-Boatswain!. More commands follow as the urgency increases. However soon afterwards comes the first power struggle of the play as we see the clash between Alonso and the Boatswain. This heats up the intensity of the storm as the Boatswain, first tries to politely tell the king to keep below the deck, then loses his patience and almost commands the king to return to his cabin. You can see how exasperated the Boatswain becomes though the three responses he gives.

Cost

Cost Nowadays the issue of public health goes beyond the boundaries of the certain countries. We live in a highly globalized world and can effectively join our efforts in order to overcome mass diseases in the poorest countries. The issue of cost-effectiveness becomes one of the central points on the agenda of the global medical organizations and institutions.Advertising We will write a custom essay sample on Cost-effectiveness of the global health programs specifically for you for only $16.05 $11/page Learn More The aim of this essay is to characterize the criteria of cost-effectiveness and its impact on the global health programs and interventions. The finding of the cost-effective solution boils down to the determination of the interventions creating the greatest good for the greatest amount of people at the lowest cost (Jacobsen, 2009). It is unarguable fact that the access to the healthcare in the poorest countries is restricted by the severe economic distre ss in these countries. That is why the balance of cost and benefits should be found in the global health programs. The overcome of the mass diseases in the certain regions of our planet cannot be achieved without healthcare cost reduction. Jacobsen (2009) states that â€Å"one way to calculate cost-effectiveness is to compare the cost of an intervention with the resulting increase in years of healthy life† (p. 286). A lot of global medical organizations and institutions refer to the measure of DALY which is the disability-adjusted life years. Levine (2007) mentions that the success of the recent programs has been proved by the inventions that used â€Å"a cost-effective approach, determined by a threshold of about $100 per DALY (disability-adjusted life years) saved† (p.25). However, the global medical programs and interventions differ depending on their particular purpose. The vertical programs which are disease specific and centrally managed assume the delivery of me dicines and services outside the ordinary medical servicing (Levine, 2007). These programs have proved their effectiveness in the low-income countries. The community-wide interventions including salt iodation and the improvement in the tobacco control in Poland refer to the traditional public health interventions which have proved to be successful (Levine, 2007). All of these programs were developed for the achievement of the specific purpose, thus concentrating resources on the aid to certain groups and maximizing the effective result in these groups.Advertising Looking for essay on health medicine?

Many of the global health programs concentrate their efforts on the technological innovations in the healthcare system. However, the cost of their implementation and usage is hardly to be affordable to the low-income countries. Levine (2007) states that â€Å"the technological innovation led to better health only because of a concerted and large-scale effort to make it available at cost affordable to developing countries and donor agencies† (p. 29). The cooperation of the private and public sectors are necessary to achieve the cost-effectiveness of the new medical technologies (Levine, 2007). In order to summarize all above mentioned, it should be said that the criterion of cost-effectiveness is the important measure of the overall success of the health program. The reduction of cost for maximizing the number of people treated is one of the main goals of the global health interventions in the low-income countries. In this context, finding of the cost-effective solution is vital for saving lives and increasing the life expectancy in the developing world. The global health organizations should employ this criterion for the determination of the overall effecti veness of the initiated program. References Jacobson, K. H. (2009).

Cost Introduction Recently the basis of utilizing antiretroviral treatment for South African citizens suffering from AIDS has been use of highly active antiretroviral treatment (HAART), which consists of two nucleoside formulations along with either a non nucleoside formulation or a protease inhibitor provided concurrently to persons suffering from Aids on a continuing mainstay.Advertising We will write a custom coursework sample on Cost-effectiveness of Highly Active Antiretroviral Therapy in South Africa specifically for you for only $16.05 $11/page Learn More HAART is considered to be more effective to reduce HIV progression and morbidity in relation to other analogues like nucleoside reverse transcriptase inhibitor (NTRI) [1]. However, constantly mounting pressure on clinical service monetary allocations makes it necessary that clinical service technology shows not only wellbeing and effectiveness but in addition cost efficacy. Financial analyses bring about details regarding cost effectiveness through contrasting the cost and gains of a single medical service project to the cost and/or advantageous of an agenda that it is at the end targeting to substitute. Although highly active antiretroviral treatment is currently popular therapy for people suffering from AIDS in South Africa, insufficient proof was documented regarding its cost efficacy before its extensive utilization. Furthermore, as it has of late been proposed that the guideline for financial analysis should be dynamic and needs to proceed prior to technologies has become reference healthcare policy [2-5] instead of a single event, the study aims to examine the cost efficacy of HAART in South Africa. Methods Study modeling A Markov modeling comprising 38 twelve-month durations was utilized in simulating the progression regarding HIV scourge and in estimating the cost, effect and cost efficacy [4, 6] of highly active antiretroviral treatment alternative [7]. The design of the Ma rkov modeling was based on frameworks earlier utilized in approximating the cost efficacy of HAART [8, 9]. Markov states were developed as per the CD4 numbers, which offer evidence upon which cost efficacy of AIDS therapy is modeled. Cost efficacy was examined through dividing the cost variance with the variance that occurs in health results, that is, quality adjusted life year (QALY) or life year (LY) added between the HAART and No-HAART alternatives in producing incremental cost efficacy ratios (ICERs) [5]. Probabilistic simulations (Monte-Carlo) evaluation was developed based on an imaginary sample of 2000 AIDS patients (1000 in HAART cohort and 1000 in No-HAART cohort) who were aged 18 when they entered the Markov modeling, thus enabling investigation on the impacts of indecision regarding the various variables.Advertising Looking for coursework on business economics?

Get your first paper with 15% OFF Learn More The simulati ons were carried out numerous times to enable representation of a number of various medical events during evaluations. The reference cost of No-HAART treatment, time of HAART therapy impact and the consumption weightings were stated to be mainly â€Å"possible† values, in combination to lower-and-upper boundaries, instead of one-point approximates, in a quest of describing more practical events [3, 10]. A more potential value was set equivalent to documented average value while lower and upper boundaries were set at 0.95 confidence levels. The Markov modeling comprised 4 health conditions: 200=CD4350 cell/micro liter, 50CD4200 cell/micro litre, AIDS and Death. Patients entered the Markov model at the health condition 200=CD4350 cell/micro liter. After each cycle, patients’ HIV state either remained unchanged, advanced or reversed. Figure 1: Health conditions (see rectangles) and transiting probability (see arrows) comprised in Markov modeling (arrow indicates directio n of possible transition) Therapy impacts (transiting probability) Overall effect of therapy on HIV progressions were evaluated utilizing examinable data from South Africa. Information on ART naive patients who commenced using HAART and who in addition had 200=CD4350 cell/micro liter formed part of the cohort. For patients getting HAART treatment, HIV progressions were examined utilizing data from 1000 patients who enrolled for ART therapy over the research duration. HAART effect on HIV progressions were examined utilizing details on 1000 patients who commenced full antiretroviral treatment. Follow-ups for such patients were expurgated during their final visit and/or death, and comprised information prior to treatment, as therapy adjustments at this period would have no impact on progression probability. The uncertainty to die was accounted not only for the concerned age-adjusted death degree in the sample but also for the threat of receiving AIDS [5]. For the sake of this study, a patient in the two cohorts who passed on during treatment duration was deemed to have passed on because of an AIDS based circumstance. However, this can over approximate the death cases linked to HAART, since a larger percentage of death cases are expected to be non-AIDS-based in this cohort [9, 11].Advertising We will write a custom coursework sample on Cost-effectiveness of Highly Active Antiretroviral Therapy in South Africa specifically for you for only $16.05 $11/page Learn More Antiretroviral unresponsive people suffering from AIDS are regarded to be having an enhanced first reaction to therapy in relation to people who have earlier been introduced to antiretroviral [2, 3, 9]. Thus, the model comprised transiting probabilities from one health state to another (see table 1). Because individual follow ups were uncensored when a patient progression along the Markov cycles, the modeling absolutely integrates succeeding therapy malfunction and adjustments during treatment. The first and succeeding pair of transiting likelihoods in each therapy was computed by classifying patients as per their initial health status, 12 months and during 24 months after commencing therapy. A patient who passed on during the 12 months was added to the death state while a patient who had opportunistic disease or whose final HIV based condition was over  ½ a year prior to the expected time, were grouped as per their CD4 amount during the event (200=CD4350 cell/micro liter, 50CD4200 cell/micro litre). The CD4 counts during each period were approximated utilizing linear regression between the prevailing counts and counts after the specified time period. In case no CD4 values were found after this period, the CD4 counts were approximated to be the number prior to this period, as long as the value was determined during the first quarter of that period [12]. Finally, since the period of the impact of HAART is greatly not known, in the basic evaluation it was presumed that extra medical effects of HAART were assumed to be for 60 months with a least and optimum period of 24 and 96 months, in that order. However, the extra cost of HAART in relation to No-HAART treatment was presumed to be separate from medical impact and to prolong up to either the modeling stopped or a person passed on, whichever came early, so as to create conventional estimates of cost efficacy [13, 14]. Table 1: Yearly transiting probability based on a group of persons suffering from AIDS who were listed for therapy in South Africa To state From state 200=CD4350 50CD4200 AIDS Death 200=CD4350 # 0.21 (0.18-0.24) # 0.20 (0.15-0.35) 50CD4200 # # 0.45 (0.35-0.55) 0.25 (0.15-0.35) AIDS # # 0.40 (0.3-0.5) NB: all people entered the Markov model at the health condition CD4†¹ 200. # Indicates residual probabilities. All row probabilities add up to one. Also values exclude yearly age-adjusted likelihood of passing on. Transition probability Changeover pr obability based on Markov modeling is needed in specifying all necessary transitions of Markov conditions (see arrows in fig.1). For the HAART modeling, movement probability as well as 0.95 confidence interval (CI) is approximated based on Kaplan result maximum approximations of survival representing 1000 participants under antiretroviral for the initial 4 years of the study [7, 8].Advertising Looking for coursework on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Changeover probability for the No-HAART modeling was gotten from a domestic ordinary history group encompassing 1000 ART unresponsive participants. The probability of transiting from 200=CD4350 to 50CD4200 is 0.21, probability of transiting from 50CD4200 to AIDS is 0.45, probability of transiting from AIDS to death is 0.4, probability of transiting from 200 =CD4350 to Death is 0.2, and that of transiting from 50 CD4200 to Death is 0.25. Treatment cost The cost to treat people suffering from HIV with HAART treatment depended on approximates gotten from the South African Potential Evaluating System-AIDS Health Financial research [14]. The research approximated the HIV treatment requirements that were needed by more than 13 000 people suffering from AIDS in 9 hospitals in South Africa, comprising the resources attached to related diseases. Resource approximates were the associated with basic individual costs gotten from an earlier research [12]. This cost was in addition combined with approximates of the social service cost linked to various phases of HIV [15], implying that such an evaluation was carried out based on South African public monetary view. The costs to treat people using HAART were approximated as the cumulative costs to treat people with HAART plus the costs to treat HIV related complications. Discounted per case life-time cost were 2,232,614 for No-HAART against 8,131,018 for HAART. The discounted incremental cost (ICER) per QALY added was 10,533. The ICER value was less than per life year added and fairly greater after discounting costs at 3%. No additional cost was added to this assessment. In the basic evaluation, cost was discounted at 3% in a year but medication impact remained undiscounted, as per the current South African policies, apart from the sensitivity assessment [6, 7]. All documented expenditures were based on 2008 data [12]. Table 2: Total costs of HAART treatment in 2008 (US dollars) and utility weightings based on HIV condition [ 12]. 200=CD4350 50CD4200 AIDS Death Cost 500 750 1500 0 SE 100 150 300 Utility 0.85 0.70 0.50 0 95% CI 0.80-0.90 0.65-0.75 0.45-0.55 0 CI = Confidence Interval SE = Standard error Quality of life Currently, only a few utility weightings are available to people suffering from AIDS. The most appropriate information was generated from a cohort comprising 249 Canadians suffering from HIV utilizing the health utility indexes mark II [12]. However, except for the fact that such information was generated for Canadian individuals, it was only evaluated utilizing multivariate modeling, implying that absence of variations in documented weightings between these two cohorts could be described using elements like before therapy background, period of the last HIV associated situation, threat class or opportunistic diseases. The Mark II comprises of a health condition categorization method and a corresponding pair of utility weightings [12, 13]. The categorization method has seve n measures, consisting of mobility, pain and healthcare. The utility weighting was computed through requesting 1000 Canadians to respond to a visual-analogue scale and through scoring the responses using standardized gable value. Sensitivity evaluation Basically, the greatness of the ICERs measured against their compound variables, and therefore the certainty level that may be associated with the basic cost efficacy approximate, can be examined utilizing sensitivity evaluation [4, 15]. In this study, 1-way sensitivity evaluations were carried out on different elements, comprising the extra costs associated with HAART in order to emphasize their significance to determine cost efficacy. This was attained through varying the number associated with one element (for example cost of HAART) while leaving all other numbers in the modeling process constant, and through analyzing the succeeding variation in ICER value. Elasticity, which measures the effect of adjusting various parameters on t he ICERs, was in addition computed for some elements like the ICER’s % change against a % change in the variable. Overall, a higher elasticity means an enhanced importance of the variable to determine cost efficacy. Negative elasticity is linked to a decrease in the ICER, that is, an increase in cost efficacy, while positive elasticity indicates that the ICER value increased, implying a reduction in cost efficacy. Analysis/Results In this study evaluation, the cumulative cost, life years and QALYs for people who did not use HAART for 38 years was 2232614, 90 and 1964, in that order (see table 3), and for people treated with HAART, the cost, life years and QALYs linked to therapy was 8131018, 115 and 2524 respectively, implying that the cost for treating individuals and impacts were boosted by approximately 36.3 per cent and 22.1 per cent, in that order, generating an ICER value of 238543 for one year added. Approximately 24 % of the cost of highly active antiretroviral treatm ent was due to the costs to provide HIV drugs. Adjusting life years in the health conditions resulted to an ICER value of 10533 in each QALY added (Table 3). Also the cost per case amounted to $138 for participants under HAART and $250 for patients not under HAART. The mean cost of each patient case amounted to $267. 71% of patients led to a mean weighted cost amounting to $162 per case. The cost of each patient treated amounted to $622. The percentage for each case cost associated with treatment varied between 4-34% for patients under HAART. The total yearly cost for HAART including cost of drugs amounted to $438 in a year whereas the highly active antiretroviral therapy cost totaled to $162 in a year. Second phase was twice the cost of first phase, amounting to $952 in a year. The cost of checking CD4 and drug costs amounted to approximately $25 in each quarter. The cost in each Markov state has been computed through multiplying health service use and per case costs. HAART cost wa s greatest for patients bearing 50CD4200 during the initial 12 weeks under HAART, amounting to $548 not including cost for dead patients. Cost remained steady, but shifted to more than $340 in every year period after which second-phase medication was included. No-HAART cost in the 50CD4200 and 200=CD4350 classes amounted to $250 (undiscounted) and to $223 with discounts using an overall discount factor of 22. Table 3: Cost, impact and cost efficacy of HAART in relation to No-HAART Life years QALYs Costs Incremental cost/LY Incremental cost/QALY No-HAART 90 1964 2232614 HAART 115 2524 8131018 238543 10533 Difference 25 560 5898404 Incremental value cannot directly match because of the error of rounding off Sensitivity evaluation The outcomes indicated that the ICER values were slightly elastic to a one percent increase of the per year probabilities of HIV advancement and fairly elastic upon increasing the cost of HAART (with a sensitivity of 0.68). However, additio nal evaluation indicated that the ICER values were highly elastic to increasing rate of discounted cost (with a sensitivity of -7.1) and also sensitive to a discount of treating impacts per year at 1% (with a sensitivity of 10.7). The ICERs were in addition highly elastic to the presumption about the time and costs provided that HAART prolonged in having an incremental impact, the ICERs declined to about 238543 in each life year added. Furthermore, when the probable time-periods of the effectiveness of HAART were extended to six years from five, the ICERs declined to about 229070 in each life year added. Discussion This study aims at approximating the cost efficacy of complete AIDS healthcare comprising HAART based on principal costs, use, Life years and life adjusted quality years data derived from an extensive group in an industrializing nation setup. This research has initiated some improvements to reference Markov model concepts that have been use in industrialized nation HAART cost efficacy analyses such as the development of subway nations in capturing the quickly reducing use and mortality within the initial months of HAART treatment, and the availability of a Markov modeling state that reflects the stringent concept of HAART provision in South African general HAART policies. The Markov model has in addition initiated the idea to capture the main cost-determiner of healthcare via transition cost, which is gained as a patient transits to death from Markov states. Probabilistic sensitivity analyses have acquired statistics indecision with 95/100 confidence interval regarding life-time cost, results and ICER. To conclude, the outcomes generated in this study indicate that HAART is a fairly cost efficient technique to treat people suffering from HIV in relation to No-HAART. However, decreasing the costs associated with HAART would considerably enhance cost efficacy and permanent information regarding the comparable efficacy of HAART is needed so as to compl etely validate the outcomes of this study.
