Identity development in career-changing beginning teachers : a qualitative study of professional scientists becoming school teachers

This qualitative study provides a critical case to analyse the identity development of professionals who already have a strong sense of identity as scientists and have decided to relinquish their professional careers to become teachers. The study followed a group of professionals who undertook a one-year teacher education course and were assigned to secondary and middle-years schools on graduation. Their experiences were examined through the lens of self-determination theory, which posits that autonomy, confidence and relationships are important in achieving job satisfaction. The findings indicated that those teachers who were able to achieve this sense of autonomy and confidence, and had established strong relationships with colleagues generated a positive professional identity as a teacher. The failure to establish supportive relationships was a decisive event that challenged their capacity to develop a strong sense of identity as a teacher

The role of biomedical physics-engineering in the development of medical device education for the healthcare professions

Biomedical physics-engineering involves the development of medical devices and their effective, safe and efficient application in the clinical milieu. Modern healthcare relies heavily on the twin pillars of pharmaceutical and medical device technology. Unfortunately, whilst pharmaceutical education has been given a lot of attention in healthcare professional curricular development, medical device education has been sorely lacking. Meanwhile, the array, variety and complexity of medical devices have been increasing rapidly with the swift advances in technology. On the other hand, as device education has not kept pace so have underutilization of devices and the number of instances of improper and unsafe use.peer-reviewe

Reflexive and preparatory selection and suppression of salient information in the right and left posterior parietal cortex

Attentional cues can trigger activity in the parietal cortex in anticipation of visual displays, and this activity may, in turn, induce changes in other areas of the visual cortex, hence, implementing attentional selection. In a recent TMS study [Mevorach, C., Humphreys, G. W., & Shalev, L. Opposite biases in salience-based selection for the left and right posterior parietal cortex. Nature Neuroscience, 9, 740-742, 2006b], it was shown that the posterior parietal cortex (PPC) can utilize the relative saliency (a nonspatial property) of a target and a distractor to bias visual selection. Furthermore, selection was lateralized so that the right PPC is engaged when salient information must be selected and the left PPC when the salient information must be ignored. However, it is not clear how the PPC implements these complementary forms of selection. Here we used on-line triple-pulse TMS over the right or left PPC prior to or after the onset of global/local displays. When delivered after the onset of the display, TMS to the right PPC disrupted the selection of the more salient aspect of the hierarchical letter. In contrast, left PPC TMS delivered prior to the onset of the stimulus disrupted responses to the lower saliency stimulus. These findings suggest that selection and suppression of saliency, rather than being "two sides of the same coin," are fundamentally different processes. Selection of saliency seems to operate reflexively, whereas suppression of saliency relies on a preparatory phase that "sets up" the system in order to effectively ignore saliency

An inventory of biomedical imaging physics elements-of-competence for diagnostic radiography education in Europe

Purpose: To develop an inventory of biomedical physics elements-of-competence for diagnostic radiography education in Europe.Method: Research articles in the English literature and UK documentation pertinent to radiography education, competences and role development were subjected to a rigorous analysis of content from a functional and competence analysis perspective. Translations of radiography curricula from across Europe and relevant EU legislation were likewise analysed to ensure a pan-European perspective. Broad Subject Specific Competences for diagnostic radiography that included major biomedical physics components were singled out. These competences were in turn carefully deconstructed into specific elements-of-competence and those elements falling within the biomedical physics learning domain inventorised. A pilot version of the inventory was evaluated by participants during a meeting of the Higher Education Network for Radiography in Europe (HENRE), held in Marsascala, Malta, in November 2004. The inventory was further refined taking into consideration suggestions by HENRE members and scientific, professional and educational developments. Findings: The evaluation of the pilot inventory was very positive and indicated that the overall structure of the inventory was sensible, easily understood and acceptable – hence a good foundation for further development. Conclusions: Use of the inventory by radiography programme leaders and biomedical physics educators would guarantee that all necessary physics elements-of-competence underpinning the safe, effective and economical use of imaging devices are included within radiography curricula. It will also ensure the relevancy of physics content within radiography education. The inventory is designed to be a pragmatic tool for curriculum development across the entire range of radiography education up to doctorate level and irrespective of whether curriculum delivery is discipline-based or integrated, presentation-based or problem-based. It is suggested that the methodology used in the evolution of the inventory be applied to the development of inventories of elements-of-competence for other learning domains within health professional curricula.peer-reviewe

Maltese radiographers’ attitudes towards continuing professional development : an initial study using concept maps

Purpose: The Council for the Professions Complementary to Medicine in Malta recently published a draft document regarding the introduction of mandatory continuing professional development (CPD) for radiographers. This study explored the attitudes and motivators of Maltese radiographers prior to the implementation of mandatory CPD in order to provide the necessary information required by management to develop CPD successfully. Concept maps are used as part of a methodology to analyse qualitative data. Methods: All radiographers working in the National Health Service were invited to complete an anonymous web-based questionnaire. Results: The study showed that participants generally had a positive attitude towards CPD but were concerned about the mandatory aspect. The participants were mostly motivated by increasing professional knowledge, updating existing qualifications, and enhancing the status of the profession as a whole. Radiographers identified several difficulties with respect to CPD participation, such as lack of funding, lack of management support, and not enough local CPD opportunities. CPD participation was also negatively influenced by family commitments. Conclusion: The study showed that the majority of radiographers were self-motivated to engage in CPD activities, but there were some concerns. Based on these results, the authors suggest recommendations for allaying apprehension and producing the necessary conditions for a successful mandatory CPD scheme.peer-reviewe

Pulling offshore and staying onshore: A framework for analysis of offshoring dynamics

Given that the force of offshoring is one of the most important economic changes in the early 2000s it is vital to understand what propels it further. The landscape of offshoring is such that firms in the wealthy nations (onshore) have already off-shored, sometimes extensively. As researchers, we need to ask not whether the firm will offshore, but rather how far the firm will go offshore and what are the subtle factors that are driving this offshore decision process. Therefore, in this paper we propose a framework in order to understand the firm-level decisions that are not as well understood and not as well researched. There are a number of key variables that we already collectively know about offshoring. First, we already know that offshoring is driven by low wages and large labor pools in India, China and elsewhere. Thus, everything else being equal, work will flow to the less expensive offshore locations. © 2009 Springer Berlin Heidelberg

Glycosylated haemoglobin (HbA1c) and cortisol levels on admission to intensive care as predictors of outcome

Objective: To evaluate the predictive value of glycosylated haemoglobin and cortisol on admission, in critical care patients. Design: Prospective, observational, single centre study. Setting: 14 bedded Intensive care unit of a tertiary-level university hospital. Patients: 124 consecutive emergency medical and surgical patients. Methods: Data collected on admission included patient demographics, medical history, medication, diagnosis, type of nutrition, TISS28 score, serum blood glucose, Glycosylated haemoglobin (HbA1c), cortisol, mean arterial blood pressure, and the use of inotropes in the first 24hrs. Daily baseline tests included complete blood count, urea and electrolytes, creatinine, twice weekly liver function tests. The primary outcome measure was intensive care unit mortality. Secondary outcome measures were ITU stay, days of ventilation, peak urea, peak creatinine, lowest platelet count, peak bilirubin, lowest Pa/FiO2, and the number of transfusions. Measurements and results: 124 patients (mean age 56.2 years SD 23.2) were included. Regression analysis was used to identify any potential predictors of outcome: HbA1c levels on admission were not found to be significantly associated with mortality (p=0.51), or any other secondary endpoints listed above. However, subgroup analysis revealed a predictive role of HbA1c with regards to length of ITU stay (p= 0.01) and number of days of ventilation (p=0.007) in those patients with a history of diabetes. Glucose level on admission emerged as an independent marker of mortality (p=0.009). Conclusions: This study suggests that HbA1c may not be a predictor of outcome in the general ITU population but may be of predictive value in diabetic ITU patients. On the other hand, blood glucose levels on admission emerged as a predictor of mortality, whilst no association was found between HbA1c and cortisol levels on admission.peer-reviewe
