Extract of sample "Radiographer Training in the Red Dot System: A Comparison of Articles"

Download file to see previous pages These medical professionals are in need of further education and, though obviously dedicated, are most often "left with limited local educational support to continue in their clinical role in A & E." (McConnell and Webster 2000: 608) The question has been raised as to the effectiveness of offering a short course of training to these radiographers and, once further instruction has been completed, whether there is a statistically significant improvement in their performance. In the two studies cited above, the authors have undertaken the task of analyzing the skills of radiographers in various hospitals, providing them with a programme of instruction, and then evaluating any significant improvement in their performance. There are three quantifiable categories for this analysis: Sensitivity, which is the ability to spot traumatic abnormalities; Specificity, which is the ability to identify normal skeletal appearance; and Accuracy, which is the overall ability to provide the casualty officer with useful, precise information. The scope of this paper is to critically evaluate and compare the two articles.
The stated purpose and objectives of the two articles are clearly similar; as articulated by Hargreaves and Mackay, the studies are "aimed to investigate whether the introduction of a training programme for radiographers...could increase their ability to exclude fractures within a red dot system." (2003: 283) While both articles undertake and accomplish this task with varying degrees of clarity, the format and layout of the Hargreaves article provides a clearer statement of the intent of the study. The McConnell paper uses a textual abstract to frame the issue and, though sufficient for the purpose of outlining the content of the piece, it infers the objective more obliquely. The reader clearly understands the purpose and objectives only after reading both the abstract and the article. Hargreaves, however, provides a clear statement of the specific purpose at the beginning of the article, making the focus of the piece clearer from the start. This discrepancy can perhaps be accounted for by noting that the earlier article, McConnell, is addressing the somewhat narrower parameter of a "short course of study" within the context of a needs-analysis survey (2000: 608) while Hargreaves, which relies on McConnell as a source in its works cited, undertakes the broader question of generally improving performance through training without the constraints of survey parameters or course length. In terms of clarity, the more recent piece does a better job of stating the purpose and objectives through its format which allows the reader to come into the article knowing exactly what the purpose and objectives are.
Results - presentation and ease of interpretation
Both articles offer a clear presentation of their conclusions, substantiated by data tables or statistical figures. In their discussion sections, the interpretation of the data is clearly articulated and referenced. Both rely on the combination of narrative and tabular data sets to establish the results of their study. When the text of the discussion is read in conjunction with the data, the reader is able to easily understand the information ...Download file to see next pagesRead More

Analysis of Red Hat Linux Operating System

... system. This bundling strategy is an important feature for maintaining working components within a single system, and it is one that seems to differentiate Red Hat even from its fellow Linux distributions (Amprimoz, 2011). Especially for enterprise solutions, Red Hat seems to make more sense than other Linux distributions. Compared to other distributions like Debian and Ubuntu, which focus more on the user-friendly side of the Linux market space, Red Hat is a more established name in large-scale solutions. This is the reason why Red Hat has an advantage in its compatibility with third-party software and an advantage in its training and certification program. While these advantages are products of how people use Red Hat, not in how...

The Interprofessional Practice and the Health Care System

This is also the position Stone (2007) takes in the quote under discussion.
Furthermore, Stone goes on to declare that Australia has been very slow to implement this practice as compared with other countries and government agencies. One of the primary reasons is that the public policy system in Australia is quite complex and the decision-makers have not come into agreement on where to place it in the policy matrix. This leaves Interprofessional Practice and Education in the dark (or the cold) as far as strategic planning for implementation as well as placing itself within the funding cycles of the government disbursements.

The absorption of infra red rays by newly formed aerosols was the cause of this local heating (McCormick, Thomason, and Trepte, 1995). This kept warm the lower tropical stratosphere for the rest of the year and eventually, these aerosols were transported into the troposphere thereby impacting the cloud optical properties and changing Earth’s radiative processes (McCormick, Thomason, and Trepte, 1995). Earth’s sunlight reflectivity is enhanced in this process and so there is a cooling effect on Earth. But all the same, there is also a green house warming effect caused by the aerosols absorbing infra red rays. The former was found to be more...

Juvenile Delinquency and Education: A Comparison of Public and Private Education

Perhaps a reason for that was that child mortality rates were high. It was not considered feasible to form attachments with children. They were left up to nature and the survival of the fittest approach. However, at the end of the eighteenth century, the age of “The Enlightenment” brought about changes regarding the status of children. This new cultural awareness was a part of the humanist movements of the age. They were now considered to be the welfare and responsibility of the state. The strict disciplinarian ways were giving way to nurturing and concern. At this point, children were now considered a distinct group.
