Objectives:

The research objectives were to (1) describe the current and future roles of hospital librarians and the challenges they face and (2) find evidence supporting the hypothesis that librarians are essential to hospitals in achieving the organizations'' mission-critical goals.

Method:

The authors used results from a previous research study that identified the five organizational mission-critical goals important to hospital administrators and then searched the literature and solicited examples from hospital librarians to describe the librarian''s role in helping hospitals achieve these goals.

Results:

The literature supports the hypothesis that hospital librarians play important roles in the success of the hospital. Librarians support quality clinical care, efficient and effective hospital operations, continuing education for staff, research and innovation, and patient, family, and community health information needs.

Conclusion:

Hospital librarians fulfill many mission-critical roles in today''s hospital, providing the right information at the right time in a variety of ways to enhance hospital and medical staff effectiveness, optimize patient care, improve patient outcomes, and increase patient and family satisfaction with the hospital and its services. Because hospital librarians and their services provide an excellent return on investment for the hospital and help the hospital keep its competitive edge, hospital staff should have access to the services of a professional librarian.

Highlights

  • A review of the literature supports the hypothesis that services of the professional librarian result in:
    • enhanced staff effectiveness,
    • optimized patient care,
    • improved patient outcomes, and
    • increased patient and family satisfaction with the hospital and its services.

Implications

  • Because hospital librarians and their services provide an excellent return on investment for the hospital and help the hospital keep its competitive edge, hospital staff should have access to the services of a professional librarian.

Radiological images show anatomical structures in multiple planes and may be effective for teaching anatomical spatial relationships, something that students often find difficult to master. This study tests the hypotheses that (1) the use of cadaveric computed tomography (CT) scans in the anatomy laboratory is positively associated with performance in the gross anatomy course and (2) dissection of the CT‐scanned cadaver is positively associated with performance on this course. One hundred and seventy‐nine first‐year medical students enrolled in gross anatomy at Boston University School of Medicine were provided with CT scans of four cadavers, and students were given the opportunity to choose whether or not to use these images. The hypotheses were tested using logistic regression analysis adjusting for student demographic characteristics. Students who used the CT scans were more likely to score greater than 90% as an average practical examination score (odds ratio OR 3.6; 95% CI 1.4, 9.2), final course grade (OR 2.6; 95% CI 1.01, 6.8), and on spatial anatomy examination questions (OR 2.4; 95% CI 1.03, 5.6) than were students who did not use the CT scans. There were no differences in performance between students who dissected the scanned cadavers and those who dissected a different cadaver. These results demonstrate that the use of CT scans in medical gross anatomy is predictive of performance in the course and on questions requiring knowledge of anatomical spatial relationships, but it is not necessary to scan the actual cadaver dissected by each student.

The purpose of this qualitative case study was to explore what aspects of two first‐year elementary teachers' practices were most consistent with an inquiry‐based approach, what PCK served as a mechanism for facilitating these practices, and what experiences have mediated the nature and development of these teachers' PCK. For each of the participants data included audio‐recorded interviews, video‐recorded classroom observations, lesson plans, and samples of student work. Data analysis illustrated that both participants engaged their students in question‐driven investigations, the use of observational data, making connections between evidence and claims, and communicating those claims to others. Moreover, there was clear evidence in the findings of the study that a considerable degree of coherence existed between the two participants' knowledge on one hand and their instructional practices on the other hand. The participants perceived specific learning experiences during their programs as being critical to their development. The contribution of this study lies in the fact that it provides examples of well‐started beginning elementary teachers implementing inquiry‐based science in 2nd and 5th grade classrooms. Implications of the study include the need for the design of university‐based courses and interventions by which teacher preparation and professional development programs support teachers in developing PCK for scientific inquiry and enacting instructional practices that are congruent with reform initiatives. © 2010 Wiley Periodicals, Inc.

Supervised exercise has shown benefits for subjects with asthma, but little is known about the effectiveness of unsupervised physical activity on this population. We investigated the effects of a 12-week unsupervised pedometer-based physical activity program on daily steps and on clinical and psychological parameters of adults with asthma. Clinically stable adults with moderate to severe asthma were encouraged to take daily 30-minute walks and were randomized to pedometer and control groups. The pedometer group received pedometers and individualized daily step targets. Changes in daily steps (average of steps taken during six consecutive days), six-minute walk test (6MWT), health-related quality of life, asthma control and anxiety and depression levels were assessed 12 weeks after intervention and 24–28 weeks after randomization. Thirty-seven participants were recruited and 30 completed the intervention. At 12 weeks, the groups differed significantly in daily steps (adjusted average difference, 2488 steps; 95% confidence interval [CI], 803 to 4172; p = 0.005) and in the 6MWT (adjusted average difference, 21.9 m; 95% CI, 6.6 to 37.3; p = 0.006). These differences were not significant 24–28 weeks after randomization. The program was effective in increasing daily steps of adults with moderate to severe asthma 12 weeks after intervention.  相似文献

This paper shows how parents’ perceptions of parent–teacher relationship practices differ between different types of schools with respect to children’s special needs and the socio-economic status of these children. Using a questionnaire, we compare parents’ views from two special education schools, two at-risk schools serving low SES-children, and two mainstream primary education schools in the southern part of the Netherlands. The theoretical framework is based on Epstein’s Model of Parental Involvement. The results illustrate that parents and teachers in special education and at-risk schools are very much accustomed to ‘two-way communication’, in contrast to mainstream schools, and that this is valued highly by these parents. Furthermore, teachers in special and at-risk schools are more familiar with interacting with parents, involve them more in decision-making and more often co-ordinate homework practice with parents.  相似文献

The artist teacher project set out to facilitate trainee teachers’ creative practice and inform their critical pedagogy in the classroom. The approach outlined in this article encouraged them to consider predictable and formulaic practice, and to question, reflect upon and challenge orthodoxies in their teaching of art, craft and design. They critically appraised their practice within a community of reflective practitioners in critical presentations, and in their reflective writing, and discussed and debated the contradictory positions between what they explored in their individual practices as artists and that experienced in the classroom. This project highlighted how fundamental the critical presentations were because the peer‐review, feedback and support, facilitated dialogue in a creative, dynamic space and community of practice. These ‘crits’ also became a forum for airing frustrations and trying to come to terms with the re‐emergence of their artist identities while at the same time, having to suppress many of their convictions and ideals in order to conform to what they found on school placement.  相似文献

Abstract

The assessment of nutrition and activity in athletes requires accurate and precise methods. The aim of this study was to validate a protocol for parallel assessment of diet and exercise against doubly labelled water, 24-h urea excretion, and respiratory gas exchange. The participants were 14 male triathletes under normal training conditions. Energy intake and doubly labelled water were weakly associated with each other (r = 0.69, standard error of estimate [SEE] = 304 kcal · day?1). Protein intake was strongly correlated with 24-h urea (r = 0.89) but showed considerable individual variation (SEE = 0.34 g · kg?1 · day?1). Total energy expenditure based on recorded activities was highly correlated with doubly labelled water (r = 0.95, SEE = 195 kcal · day?1) but was proportionally biased. During running and cycling, estimated exercise energy expenditure was highly correlated with gas exchange (running: r = 0.89, SEE = 1.6 kcal · min?1; cycling: r = 0.95, SEE = 1.4 kcal · min?1). High exercise energy expenditure was slightly underestimated during running. For nutrition data, variations appear too large for precise measurements in individual athletes, which is a common problem of dietary assessment methods. Despite the high correlations of total energy expenditure and exercise energy expenditure with reference methods, a correction for systematic errors is necessary for the valid estimation of energetic requirements in individual athletes.  相似文献

The aim of this observational study is to explore how history teachers promote historical contextualisation in their lessons. Historical contextualisation is the ability to situate phenomena and individuals’ actions in the context of time, historical location, long-term developments, or specific events to give meaning to these phenomena and actions. Using the Framework for Analysing the Teaching of Historical Contextualisation (FAT-HC), five trained raters observed eight history teachers twice. To further analyse the observation scores, the FAT-HC items were divided into eight categories while distinguishing between items that demonstrate historical contextualisation and items focusing on engaging students in historical contextualisation processes. The results indicate that the teachers in the sample did not explicitly promote historical contextualisation in their lessons. No teacher obtained a mean FAT-HC score >2.00 on a four-point scale. The teachers mainly demonstrated historical contextualisation, while engaging students in historical contextualisation processes was observed far less often. The findings can be used to help teachers formulate domain-specific instruction to promote students’ ability to perform historical contextualisation.  相似文献

The aim of this explorative study was to develop and test a pedagogy aimed at promoting students’ ability to perform historical contextualization. Teaching historical contextualization was conceptualized in terms of four pedagogical design principles: (1) making students aware of the consequences of a present-oriented perspective when examining the past, (2) enhancing the reconstruction of a historical context, (3) enhancing the use of the historical context to explain historical phenomena and (4) enhancing historical empathy. The effectiveness of these principles was explored in a lesson unit focusing on the seventeenth and eighteenth centuries. In a quasi-experimental pre-test–post-test design with experimental and control conditions, the effects of the pedagogy on 15- and 16-year-old students’ ability to perform historical contextualization were examined (n = 131). The results indicated that students in the experimental condition significantly improved their ability to perform historical contextualization compared to students in the control condition. These findings could be used to help teachers and other educational professionals design and implement historical contextualization tasks and instructions.  相似文献
