Emergency medicine (EM) has expanded rapidly since its inception in 1979. Workforce projections from current data demonstrate a rapid rise in the number of accredited EM residency programs and trainee positions. Based on these trends, the specialty may soon reach a point of saturation, particularly in urban areas. This could negatively impact future trainees entering the job market as well as the career plans of medical students. More time and resources should be devoted to obtaining accurate projections, assessing the distribution of emergency physicians in rural versus urban settings, and implementing central workforce planning to protect the future of graduating trainees.  相似文献

With the increasing inclusion of special needs children in regular classrooms, experiences which encourage positive attitudes toward the disabled are essential. The purpose of this project was: 1) to examine the thinking and attitudes of young children regarding the capabilities of disabled children and the potential for friendship and 2) to assess the effectiveness of children's literature and related activities in influencing attitudes toward the disabled. Results suggested that children's attitudes were generally positive and realistic regarding the capabilities and the potential for friendship with the disabled. The use of selected children's books and book related activities positively influenced children's attitudes.  相似文献

Despite instructors' belief that class readings are integral to the learning process, only 20–30% of undergraduate students complete required readings. Failure to complete course reading has been associated with declines in exam and research performance. This article first offers a brief review of the literature on why students do not complete course readings: 1) unpreparedness, 2) lack of motivation, 3) time constraints, and 4) an underestimation of reading importance. We then identify approaches that encourage students to read, enjoy reading, and develop metacognitive knowledge, shown to improve learning.  相似文献

Despite the widespread application of technology in the 21st century, making informed decisions regarding its acceptance in organisations is a function of several factors, particularly in developing countries, due to factors such as rising cost of the information technology infrastructure and low technological exposure. A model that incorporated perceived ease of use (PEOU) and e-Skills to examine librarians' intention for actual library technology acceptance was tested. The correlational research design, along with a multistage sampling procedure, was applied to select samples to reduce the sample to a manageable proportion. Professional librarians and library officers in four university libraries provided the data for the study. Results showed that e-Skill is the model's strongest determinant of technology acceptance intention among librarians. Also, PEOU will significantly moderate librarians' intention towards library technology acceptance when e-Skills are insufficient. From these outcomes, the understanding of the determinants of behavioural intention captured in the Technology Acceptance Model (TAM) and the Unified Theory of Acceptance and Use of Technology (UTAT) is extended and refined.  相似文献

For Anna Morales, going back to school was an easy decision. After graduating from the University of Pennsylvania with her degree in chemistry, she took a year off from school but decided to go back. Morales knew she would need more education and experience for the career she wanted.  相似文献

As library employees retire or move on to other positions, library managers can take advantage of these opportunities to assess how well the vacant job's duties mesh with current organizational goals and needs. Positions in interlibrary loan and document delivery services (ILL/DDS) are no different. They should be evaluated and reviewed each time a vacancy needs to be filled to ensure that the expectations of the position are in line with the goals of the ILL/DDS department and the library.  相似文献

In the United States, Congress has had a long-standing interest in consumer privacy and the extent to which company practices are based on fair information practices. Previously, public policy was largely informed by anecdotal evidence about the effectiveness of industry self-regulatory programs. However, the Internet has made it possible to unobtrusively sample web sites and their privacy disclosures in a way that is not feasible in the offline world. Beginning in 1998, the Federal Trade Commission relied upon a series of three surveys of web sites to assess whether organizations post online privacy disclosures and whether these disclosures represent the U.S. definition of fair information practices. While each year's survey has provided an important snapshot of U.S. web-site practices, there has been no longitudinal analysis of the multiyear trends. This study compares a subset of equivalent individual-level web-site data for the 1998, 1999, 2000, and 2001 web surveys. Implications for using this type of research to inform public policy are discussed.  相似文献
