Reducing dose for digital cranial radiography : The increased source to the image-receptor distance approach

This investigation proposes that an increased source to the image-receptor distance (SID) technique can be used to optimize occipital frontal and lateral cranial radiographs acquired with direct digital radiography. Although cranial radiography is not performed on a routine basis, it should nonetheless be optimized to keep the dose to the patient as low as reasonably achievable, particularly because it can form part of the facial bone and sinus series. Dose measurements were acquired at various SIDs, and image quality was assessed using visual grading analysis. Statistically significant reductions in the effective dose between 19.2% and 23.9% were obtained when the SID was increased from the standard 100 to 150 cm (P ≤.05), and visual grading analysis scores indicate that image quality remained diagnostically acceptable for both projections. This investigation concludes that increasing the SID effectively optimizes occipital frontal and lateral skull radiographs. Radiology departments must be advised of the benefits of this technique with the goal of introducing an updated reference SID of 150 cm into clinical practice.Peer reviewe

Developing an Instrument to Examine Preservice Teachers' Pedagogical Development

National and international reform documents have forged blueprints for advancing science education. Coursework for preservice teachers needs to correspond to these documents by providing learning experiences that develop preservice teachers' capabilities to plan and implement reform measures. Using a pretest–posttest design, responses from 59 2nd-year preservice teachers from the same university were compared after involvement in an elementary science pedagogy coursework. The survey, which was linked to the course outcomes (constructs) and multiple indicators, measured the preservice teachers' perceptions of their development towards becoming elementary science teachers. A pretest–posttest survey linked to course outcomes can be employed to assess perceived pedagogical development of preservice teachers, which can inform further teaching practices for implementing science education reform agendas

Social ties, prior experience, and venture creation by transnational entrepreneurs

The interaction between resources, and host and home country contexts of transnational entrepreneurs (TEs), is important for understanding their strategies and hence performance of their ventures. Yet, how they deploy their unique experiences and social networks in the founding of ventures in multiple institutional contexts is less understood. Based on 15 in-depth interviews with TEs of Indian origin in the UK, and nine of their counterpart heads of transnational venture (TNV) operations, we explore the use of prior experience, and personal and industry ties in the founding of TNVs in their home country. Our findings show that the way TEs use personal and industry ties in the host and home countries is contingent on whether they have prior experience of: 1) entering the home country; 2) implementing the business opportunity underlying the TNV in the home country, respectively, with a former employer. The implications of these findings are discussed

Assessing Culture Competence Among Nurses in an Acute Care Setting

The aim of the study was to assess cultural competence among nurses in an acute care setting. A 25-item questionnaire developed by Campinha-Bacote (2003) titled Inventory to Assess Cultural Competence Among Health Care Providers (IAPCC-R) along with a demographic survey were utilized to assess cultural competence among 100 nurses in an acute care hospital. The results of the study indicated that 70% of nurses (n=63) were culturally aware and 30% (n=27) were culturally competent. There was no statistical significance between the level of cultural competence and years of experience, educational degree or self rating of \u27being culturally competent\u27. The findings of the study provide direction to strengthen cultural competence education and training among nurses and strategies to enhance the structure and processes of organization\u27s efforts to deal with diversity

A study into user acceptance of new technology: British Airways ground transport department Heathrow Terminal 5

This project was conducted with the help and encouragement of British Airways (BA) management. It was carried out at Heathrow Airport, Terminal 5 (T5) where a new Resource Management System (RMS) that is based upon Internet Protocol (IP) has been implemented. RMS has replaced traditional pen and paper and radio systems for allocating work tasks to 4,000 airport operational staff. This research project studied one application of the RMS system; the allocation of tasks to the coach drivers in the Ground Transport Services (GTS) department. The user acceptance of the RMS system by the drivers was evaluated. In the previous 20 years, user acceptance theories have been developed which have shown that increased user acceptance of new Information Technology (IT) projects significantly reduces costs and improves efficiency (Davis, 1980). The most comprehensive theory is that of Sun and Zhang (2006) who identify critical factors regarding individual user acceptance (gender, age, experience, cultural background and intellectual capability). This research project used a case study methodology: three days were spent airside at T5 observing and interviewing a sample of drivers. The project research question was: 'Can the degree of RMS acceptance by the GTS end-users be determined by factors identified in user acceptance theories?' Essentially, it was not possible to answer this question because of two reasons. First there was little difference in level of user acceptance; it was very high for all users. Second there was also very little difference in the sample and population. The drivers were all male, over 90% between 42 and 65 years of age, with similar levels of experience regarding the RMS technology and computers in general. In addition, it was not possible to measure any difference between the intellectual capabilities of the participants. A difference in the cultural background was identified; there were two ethnic groups, Asian and Caucasian. However, detailed analysis of the responses to the questionnaire demonstrated that there was no evidence of different levels of user acceptance of these groups. Recommendations to improve the testing of user acceptance theories are included in this report

Teacher Contract Non-Renewal in the Rocky Mountains

Success for students in the 21st century increasingly relies on competencies and proficiencies typically available on]y through formal educational processes. Researchers have noted the paramount importance of quality teaching as the important criterion for student success (Haycock, 1998; Marzano, 2003). Recent reforms have increased the expectation that school principals energetically address teacher evaluations and subsequently remove ineffective teachers. These recent reforms tend to have common priorities, including emphasizing high quality teaching, evaluating teachers for merit pay purposes, and linking evaluation to student performance with an emphasis on the removal of ineffective teachers from the classroom
