Techniques - Lab Report Example Calculations performed on the changes in mass revealed that the experimental mass of the NaCl was 1.464 g. The -1.942% error between the two results was attributed to experimental errors arising from the improper use of the pipets during the transfer of the solution to the evaporating dish for heating. The results obtained showed that the difference in the masses between the expected and experimental results to be small (-0.029 g), resulting in a relatively small % error of -1.942%. The % error was caused by systematic errors resulting from improper use of the pipet during the transfer on the 25 mL NaCl solution to the evaporating dish. Minute air bubbles might have been sucked together with the NaCl solution, resulting in a reduced amount of NaCl being heated at the end, thus lowering the final mass. The pipet used in the experiment has a precision of uncertainty of  ±0.01 mL; therefore the 25 mL taken from the volumetric flask was between 24.99 mL – 25.01 mL. This uncertainty is relatively low, making the pipet’s readings relatively precise, thus reducing the chances of random errors resulting from observational mistakes during the filling up of the pipet. a. Filling the 100 mL volumetric flask beyond the mark would lead to a lower actual (experimental) molarity. This is because adding more water will make the solution more dilute, thus lowering the molarity. b. The density of the solution would decrease if the volumetric flask was topped beyond the mark because the density if governed by the formula Density = Mass / Volume1. Therefore, increasing the volume would lead to a subsequent decrease in the density. a. Having the liquid level in the pipet being below the line would lead to a reduction of the mass of the NaCl obtained after the subsequent heating because the amount of NaCl pipet is less than the required amount. c. Using the pipet to deliver the NaCl solution to

There are a number of insights that can be gleamed from the discussion. One of the primary considerations is Morgan’s (2006) belief that mechanization is necessarily a negative for human progress; such a debate dates back as early as Rousseau’s ‘noble savage,’ with the reality remaining anywhere but clear. In either regards, it seems that at the least one can embrace the argument in that for many individuals there is oftentimes a longing for such ‘naturalness’ and that an organization only implementing mechanized inputs can only expect to produce mechanized outputs, effectively alienating this human longing. One of the prominent such considerations then is establishing objective means of avoiding such mechanization. It is clear that, to an extent, for Morgan (2006) this involves developing organizations that are more in accordance with natural human physiology. His main understanding of the brain as a form of organizational design seems contin gent on the central insight that traditional organizational mechanization is rooted in a cause and effect chain of events, whereas an organization linked to the human brain would be composed elements that act with slight independence while also containing a semblance of the whole. There are a variety of applications for such an approach. One considers Burnes’ (2009) examination of Oticon. For Burnes (2009) the critical success factor for Oticon’s turnaround was first the establishment of an overarching vision that contained strong values as a means of promoting a new organizational culture. The organization then established a learning organization wherein internal innovation and change became the fabric of the work process. One considers that these critical success factors relate directly to Morgan’s (2006) notions of the

The role of judges in making law in Uk courts Essay

The role of judges in making law in Uk courts - Essay Example This principle of precedent is also known as 'stare decisis'. This precedent should be created by a high ranking court and not from the courts of first instance. They are supposed to follow strictly the already existing law and precedents. Often these courts would be engaged in fact finding since they are not expected to hear full legal arguments of the parties. The courts administration documents and reports the decisions from 1865 in U.K. It is called now Incorporated Council of Law Reporting for England and Wales. It brings out The Weekly Law Reports and The Law Reports. The decisions that are taken as legal precedents shall have 'ratio decidendi' behind them. The ratio decidendi must be related to the law and not on factual findings. It can not also be 'obiter dictum' mentioned as a passing reference while deciding the case and shall have no legal basis for future decisions. The ratio which is binding shall have legal principles and rules considered for finding a solution for the problem in the case. The 'obiter dicta' however are treated as persuasive authority which later judges can use them for arriving at their decisions but are not bound to treat them as precedents.(UK law online) Precedent has a very important role in the common law. It ensures certainty and consistency and logical progression and development in the law. At the same time it can be rigid and also complex - what is "the law" on a subject may be very difficult to find or to state as it is spread across many cases. So, many countries (especially in Continental Europe) prefer a codified system in which laws are set out in legislation and cases which apply them may be illustrative but do not become binding. The law is also easier to find and to state and is rationally prospective rather than based on the chance event of litigation, which may give rise to laws based on extreme or unusual situations or unevenly argued cases. For example, here is the offence of murder in US Federal Law. By contrast, the law of murder in England is contained in several cases, and even having read them there may be room for doubt. As for English law, the classic definition of murder is considered to be that given by Lo rd Chief Justice Coke who (writing in the early seventeenth century) said: "Murder is when a man of sound memory and of the age of discretion, unlawfully killeth within any county of the realm any reasonable creature in rerum natura under the King's peace, with malice aforethought, either expressed by the party or implied by law, so as the party wo, or hurt etc. die of the wound or hurt etc .within a year and a day of the same." (UK Law online) Blackstone stated in eighteenth century that court decisions were mere evidence of common law. (Commentaries pp 88-9) Later Lord Esher said in 1892 that there was no judge made law as such since the judges did not make law but only applied prevailing law not previously applied authoritatively (Willis v Baddeley) However these views are refuted by late professor Cross stating "a rule stated in a precedent is law properly so called and law because it was made by the judges, not because it originated in common usage, or the judge's idea of justice and public convenience" (Cross R 1991 p 28) Cross holds that Lord Esher's view that application of existing law to new circumstances actually is similar to statement of

Peace and Free

Peace and Freedom throughout a Nation Essay Throughout the course of John F. Kennedy’s inaugural speech, he uses several persuasive appeals such as the idea of peace and freedom to inspire and gain the trust of his Nation.   In the beginning of Kennedy’s speech, he mentions that America will â€Å"pay any price, bear any burden, meet any hardship, support any friend [and] oppose any foe† (par 4) for the preservation of liberty. This is an example of parallelism clauses that make clear of Kennedy’s intent to do anything it takes for the survival and liberty. Kennedy states that both sides of a conflict should join in creating â€Å"a new world of law, where the strong are just and the weak are secure and the peace preserved† (par 19). Kennedy’s use of parallelism helps keep the people’s attention to help illustrate his key points of his speech. He later describes the â€Å"power to abolish all forms of human poverty and all forms of human life,† (par 2) that uses that power to free the peoples of the world. Meaning we have the power to destroy ourselves but it should only be used to better our nation, and create a balance of peace and freedom in the world. During this time the United States was in the beginning of the Cold War and he knew that focuses had to be on containing Communism in order to assure the American people that they were safe. Kennedy constantly reminds the American people that they are a united and strong country that can make it through anything. Kennedy begins four paragraphs in a row with the same words, â€Å"To those,† (par7-8) to illustrate that he is willing to work things out with the countries America is having problems with. His use of repetition helps him remind his country that they can make it through anything in a persuasive way. He also mentions that America can solve problems with their enemies during diplomacy several times. Kennedy amplifies his desire for peace and unity when he repeats, â€Å"Let both sides† (par 14-18) he utilizes alliteration to explain his want for unity instead of division. It is brought to our attention that â€Å"if a free society cannot help the many who are poor, it cannot save the few that are rich (par 8). In order to sustain peace and freedom throughout the nation these things like this need to be recognized. Kennedy creates a common enemy to unite the people’s pride. While discussing newly freed countries he uses a metaphor, saying, â€Å"remember that, in the past, those who foolishly sought power by ridding the back of the tiger ended up inside† (par 7). Also when he says, â€Å"the torch has been passed to a new generation of Americans† (par 3) he is using a metaphor showing that America intends to control themselves and let no one else rule them. So our Nation â€Å"should only glow from that fire [that] can truly light the world† (par 12) meaning if everyone does something to benefit the country we will succeed and live and peace. John F. Kennedy did an outstanding job with gaining the trust of his Nation during his 1961 inaugural address. The people were able to feel safe and protected with Kennedy becoming president. The fear of being taken over by a Communist nation lessened, and peace and freedom was sure to come.

Performance of Equipment Maintenance Services in Healthcare

Performance of Equipment Maintenance Services in Healthcare Performance Monitoring in Equipment Maintenance Services checklist Title Abstract Method: Introduction Choosing And Using Key Performance Indicators Benchmarking In Clinical Engineering Audit Summary Discussion And Conclusion Abstract The objective of this literature review is to deliver results to the key performance indicators in monitoring the performance of equipment maintenance services. Method: Medical equipment management, health source and Medline were used and the search was conducted using different keywords such as key performance indicators, equipment maintenance services and performance monitoring equipment maintenance services. Introduction The medical equipment management approach defines the strategies for oversight and interaction of the medical equipment’s used in treatment, diagnosis and treatment of patients. All the related procedures and policies govern event from selection to acquisition, incoming inspection and the medical equipment management. The mission is ensuring that the medical equipment used in patient care is affordable, safe, accurate and available. The scope of this plan is clinical laboratories and different health systems. (McDermott 2009) Performance indicators should be chosen with care, if not individuals tend to respond by optimizing what is being estimated and hence lose focus of the quality. There are two important questions that should be asked concerning any performance indicator. First, can the performance indicator in question lead to perverse incentives and does it have the required potential to induce the desirable changes. Key performance indicators help a company measure progress towards their set objectives. (Kyan et al. 2004) Additionally, key performance indicators help an organization present of service delivery to come up with the course of action. Different key performance indicators differ depending with the exact nature of service delivery and the company’s approach. Choosing And Using Key Performance Indicators The right indicators vary depending on the reason why the management is choosing them. All key performance indicators contain numerous hidden assumptions. For instance, the company can quote is a known guaranteed downtime percentage with the inclusion of the time when the equipment will not be required. However, at times statistical measures can be very hard to interpret, while clinical users do not consider the actual time of action. (Willson et al.2008) On the other hand process indicators appear to change more often than those that have been made to support specific improvement, and monitor the key factors affecting to quality of output. Result measures are more bound to estimate the effectiveness of initiatives to boost the service. Reasons for the poor performance should be thoroughly investigated, for instance, a reduction of 15% in monthly number of the exact routine maintenance logged in by the workers could be caused by alternative external demands or slipping internal stand ards. The steps that need to be taken to improve the services include modifying procedures and services, modifying demand or delivering more services. If an indicator has been modified to make it more strong, then it will be very important to maintain comparison with the old for long enough, to find out whether the changes have had any positive impact. Process targets can be interpreted and set in regard to local circumstances, because the detailed practice commonly varies, on the other hand, outcome indicators are directly comparable between the services when similar definitions are used (McDermott et al. 2009) Cost measures are quite sensitive to what the service chosen omits and includes. Across a typical hospital, the annual maintenance cost per item included varies widely. Detailed research will give the right guidelines on where the reduction of cost will be more effective. At this point, a lifetime strategy to costing can greatly help avoid the situation where technicians spend endless hours repairing the same equipment because the clinical staff lucks the funds required replacing it. A great sense of perspective is required, for instance, so that the total amount of time required to find the right technician can be reduced, this will help theatres to avoid great loses associated with the breakdown of equipment. The clinical engineer will be responsible for balancing urgency and cost and justifying his/her actions to the clinical staff (Gruber et al. 2012) Key performance indicators are reported and monitored to the relevant safety committees in the hospital throughput the year to provide feedback to the efficiency of the medical equipment management plan, the following performance indicators can be quite helpful if well used in a clinic set up. Critical life support performance maintenance completion rate, with a 100% goal and a requirement rationale. Second, the overall performance maintenance completion rate, the goal is 90% and the best practice to report and monitor rationale. Third is the service requests caused by user errors or mishandling, with a 10% or less gal of all the service requests that had not been planned, in this regard, the exact number of chances may be synonymous without consideration of the overall volume of all the service requests received. Mishandling mistakes with the exact requirement will have to be evaluated to find out if the trends exist, with the overall ratio that has been tracked over time providing relevant information for risk reduction. Another performance indicator is the equipment failure rendering harm to staff or the parties, the goal is zero occurrences and the best practice to report and monitor rationale (Swan et al. 2004) The next performance indicator chosen is the hazardous investigations, the main reason for choosing this key indicator was getting the right information, the rationale of choosing the hazardous investigation KPI Is all SMDA recalls, reportable events and medical equipment accident investigations will be instantly reported to the relevant safety committees. The next performance indictor chosen was the performance improvement standards. First, clinical engineering is responsible for identifying performance improvement indicators, based on the priorities that have been identified by users of the medical equipment in question, the relevant department and the environment or safety care committee. The environment or safety committee has the sole responsibility of approving the thresholds and monitors on yearly basis. All performance maintenance indicators are reported after every three months to the safety committee. The information provided is then submitted to the governing body involved via the regular reporting channels. All the elements of performance indicators can be changed upon request based on the administrative input, the institutional experience and regulatory change (Willson et al. 2004) Benchmarking In Clinical Engineering Over the years, there has been a lot of benchmarking activity with the clinical engineering sector. Clinical staff and hospitals are continually finding that there are many issues that are pushing them towards benchmarking. In this sector, we shall look at different methods in which benchmarking in the hospitals in used and the most common measures that are available. These different measures fall into different categories depending with the service they are used to measure. The outlined derivation of benchmarking measures differ between different organizations, and checking into the differences is often vibrant than opting to do a direct comparison. This results into a debate when estimate the cost against other relevant performance measures. In addition, they help guide in making evidence based decisions which integrate the quality with the worth of money. (Willson et al. 2004) In Canada, standards for evaluation and measurement of the best clinical engineering services were introduced back in 1998. To put everything in order, the Canadian biological and medical society created a review to boost the sharing of concepts. Another alternative option is making the use of external consultants to measure the service and advice on the utilization of performance indicators and quality systems to enhance it. Audit This is very important to getting and maintaining the highest quality standards. In its simplest terms, the audit compares the current and the intended practice and immediately reports on the difference. For instance, many follow a person through the maintenance process whilst looking out for any deviation from the right procedures, checking out the records and terms to ensure they have been completed successfully. This strategy is relevant to the internal audits and has the capacity of identifying whether the procedure is working as expected, unfortunately, it does not capture the power of exactly what the audit can achieve. (Willson et al. 2004) As a result, an auditor requires some level of incidence without carrying the responsibility of the area being audited single handedly, this is something that is very hard to achieve in small organizations. If this is done successfully, external audits may bring sufficient benefits mainly if the auditing was conducted by an experienced audi tor from another company. In simpler terms, a simple audit process visits are made up of: Preparation and planning: The auditor agrees to the extent of the audit in advance. Opening meeting where the auditor meets with the management representative to discuss the importance of the audit. Audit: Includes visits to several areas, interviews with the organizations staff and examination of the databases. Closing meeting: The audit meets the management to explain and share their audit findings and confirm the queries, indicating how the issues will be resolved. Audit report: The audit writes a conclusive report clearing outline recommendations for improvement. Once both parties agree to the report, it is signed and passed to the relevant bodies. Follow up: The auditor follows up checks out the corrective actions to see whether they have been completed. Organization auditing can be used to measure how technical and scientific procedures are being followed and whether they will give the right results. This perfect type of audit may be conducted by experienced professional bodies under registered national schemes. For instance, thorough checks between radiotherapy determinants for quality assurance schemes and dose delivery. Basically, it looks at the product, so that they can test a complete system that is where it differs to outline quality control. (Willson et al. 2004) Summary In this report, we have identified many reasons why a company should monitor its performance; we have also discussed the importance of integrating monitoring in a top-notch management system. We have vividly described the design of key performance indicators and looked at how they can be implemented in medical equipment management. (We have also outlined the pitfalls associated with developing and interpreting performance indicators and considered their utilization in practice. We have also reviewed how benchmarking can assist organizations enhance their performance. Finally, we have considered how audits should be strategized, what happens during the audit and how different groups of organizations can combine efforts and assist each other with benchmarking and mutual audit activities. (Grubel et al.2008) Discussion And Conclusion One important thing to understand is the fact that key performance indicators are not performance targets. They are put in place as monitoring facilities with the idea of moving towards the direction of the successful implementation of the procedures, policies and process. Performance indicators are categorized into two distinct groups, namely, quantitate and qualitative. (McDermott et al. 2009)There are two things that must be identified in order to use KPIs effectively; these include the points in procedures or process through which the data is gathered to support the equipment monitoring. Secondly, the locations in service where the data gathered should be presented as important information for quality management. KPI’s are important because they enable facilities to have systems in place for better management of medical equipment and devices. A few of the reasons why key performance indicators are used include more complicated, enhanced technical preventative maintenance, regularly needs consistent quality assurance and specialized user training.

Tourette Syndrome Essay -- Disorders Medical Health Essays

Tourette Syndrome Gilles de la Tourette Syndrome is one of a number of tic disorders usually first diagnosed in infancy, childhood, or adolescence. The Tic Disorders can be distinguished from one another based on duration and variety of tics and the age at onset. Tourette’s Disorder has duration of more than 12 months. The estimated incidence of Tourette’s ranges widely but is probably four to five individuals per 10,000. It occurs two to three times more frequently in males. Undoubtedly, there are numbers of other students with symptoms who have not been diagnosed. When diagnosed and treated early, many of the associated learning, emotional, and social disabilities it produces can be lessened or dealt with more effectively. The goal of any program for a person with Tourette Syndrome is to assist the person in learning and interacting productively in school and society. Toruette Syndrome is a multiple tic disorder, with motor and vocal tics present, but not necessarily concurrently, which begins in childhood and is a lifelong condition that seems to change in its manifestations and intensity. The cause of Tourette Syndrome is unknown. The basic defect is thought to be a biochemical abnormality in the ganglia of the brain. Diagnosis 1. Age of onset before the age of 18, usually between 6-7 years of age 2. Rapid, recurrent, repetitive, purposeless, and involuntary motor movements affecting multiple groups of muscles. 3. Multiple vocal tics (gr...

Hurricane Ophelia was downgraded to a tropical storm again Monday as the indecisive weather system moved slowly off the coast, its outer bands of rain not quite reaching land. Despite Ophelia’s waxing and waning strength and slow progress, residents’ attention had been focused by the devastation caused elsewhere by Hurricane Katrina. That was on the mind of Steve King as he grudgingly skipped a football game on television to move his sea kayak out of harm’s way. â€Å"They keep saying this storm is two or three days out,† he said. â€Å"I think we’re all waiting for something to happen.† Ophelia’s sustained wind speed slowed Monday morning to about 70 mph, 4 mph below the threshold for a hurricane, but it had the potential to regain hurricane strength over the next day or so, the National Hurricane Center said. A tropical storm warning and a hurricane watch were in effect from Cape Lookout south to Edisto Beach, S.C. Some calls for evacuations With the storm’s path uncertain, South Carolina Gov. Mark Sanford called for a voluntary evacuation Monday of oceanfront and riverside areas in his state’s northeastern corner. â€Å"This is a serious storm that’s got the potential to do a lot of damage and put lives in jeopardy if we don’t take it seriously,† Sanford said. In North Carolina, Gov. Mike Easley on Sunday ordered 200 National Guard soldiers to report to staging centers in the eastern part of the state. The governor also ordered a mandatory evacuation of nonresidents from fragile Ocracoke Island on the Outer Banks, reachable only by ferry. At Wrightsville Beach, lifeguards ordered swimmers out of the surf Sunday. â€Å"They are saying they don’t want anyone to even touch the water,† said Kathy Carroll, 37, of Wilmington. â€Å"Now I know how a flounder feels. I was getting tossed all over the place.† Despite the warnings, there were no long lines at Roberts Grocery in Wrightsville Beach, where customers bought chips and beer — not bottled water and batteries. â€Å"Usually, they are buying all the bread and milk,† said store manager Teresa Hines. â€Å"Some of the regulars have told me they have their hammers and nails ready just in case.† With a history of destructive storms, New Hanover County has a well-rehearsed disaster plan. But Katrina, which was a powerful Category 4 hurricane before it made landfall in Louisiana and Mississippi, was on residents’ minds even though Ophelia was only Category 1 and had been waxing and waning in strength.
