In order to determine how well medical examiners agree on the significance of certain anogenital findings in children, preselected colposcopic photographs of the anogenital area of 16 patients were shown to 170 medical examiners (82% pediatricians) who were blinded as to the history on each patient. Findings rated most frequently as being suggestive or indicative of penetrating injury included immediate anal dilatation with no stool present (85%), hymenal transection (84%), marked narrowing of the hymenal rim with notching (81%), and a posterior fourchette scar (75%). The agreement between the participants and the experts on the abnormal cases (mean 81%) was significantly higher than on the normal cases (mean 71%, p < .001) and on genital findings (78%) than on anal findings (63%, p = .000). Higher experience level (more cases seen per month) was associated with significantly higher agreement between the participants and the experts on five of eight normal cases and two of four abnormal cases. Use of a colposcope was also associated with higher overall agreement with the experts (74% vs. 44%, p < .0001).  相似文献

Over the last three decades there have been numerous surveys in Australian universities which have attempted to describe the perceptions of academic staff to various aspects of their roles. Each of these surveys appears to have been inspired by changes resulting from contemporaneous government policies and/or community expectations. Calls for “Efficiency and Effectiveness”, “Accountability”, and “Quality and Diversity”have coincided with massive expansion in the higher education system, the change from a binary system to the Unified National System, and consequent changes to student profiles, funding arrangements, and academic workloads. Academic culture, with its tradition of freedom and autonomy, has been besieged by the alien culture of managerialism with its own vocabulary of “client”, “quality assurance”, and “product”: but has this assault made any difference to how academics perceive their work and their perceptions of quality in university teaching ? This paper reports on an analysis of data (relating to academics' perceptions of their work) from surveys conducted in universities from the late 70s and throughout the 80s and 90s. The paper analyses, compares and contextualises academic perceptions across these decades, and draws some conclusions about the perseverence of academic culture under siege.  相似文献

Abstract Museum professionals strive to provide meaningful experiences for visitors. Meaningful experiences are those that provide choice and control in the exploration of ideas, concepts, and objects. In many cases, these experiences occur through an interactive component. Although a number of studies have focused on interactives in museums, the field would benefit from an intensive look at how visitors perceive of and learn from these experiences. Discussion about this topic has been sidetracked by conversations about the terminology that describes this type of experience. Drawing upon studies conducted in this area, this paper looks at the role of interactives in museums by exploring three broad themes: clarity of purpose and underlying assumptions; design factors; and social engagement and learning. In conclusion, suggestions are offered for ways that these studies might inform the development of interactive experiences.  相似文献

Journal coverage is one factor that affects the retrieval of relevant information from bibliographic databases. The aims of this study were to investigate the coverage of databases for psychiatry journals, and to assess the overlap between databases. Psychiatry journals were identified using Ulrich’s International Periodicals Directory and then analysed to see which bibliographic databases indexed the most journals. A total of 213 abstracting and indexing services were listed as indexing at least one of the 977 psychiatry journals identified. The four most frequently cited databases (PsycLIT, EMBASE, BIOSIS and MEDLINE) indexed 506 (52%) of the psychiatry journals. Of these 506 journals, PsycLIT indexed 367 (73%), EMBASE 337 (67%), BIOSIS 243 (48%) and MEDLINE 236 (47%). Combining the databases with the highest yields (PsycLIT and EMBASE) increased the number of journals indexed to 461 (91%). The four databases combined accounted for 90% of all psychiatry journals found to be indexed by at least one abstracting and indexing service. More than 400 journals were not indexed at all. Variations in the overlap between PsycLIT, EMBASE, BIOSIS and MEDLINE, and the high proportion (35%) of journals indexed in only one of these four databases emphasize the importance of searching more than one or even two databases to ensure optimal coverage of the literature.  相似文献

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.

Connections between adolescents’ social information processing (SIP), moral reasoning, and emotion attributions and their reactive and proactive aggressive tendencies were assessed. One hundred mostly African American and Latino 13‐ to 18‐year‐olds from a low‐socioeconomic‐status (SES) urban community and their high school teachers participated. Reactive aggression was uniquely related to expected ease in enacting aggression, lower verbal abilities, and hostile attributional biases, and most of these connections were mediated by adolescents’ attention problems. In contrast, proactive aggression was uniquely related to higher verbal abilities and expectations of more positive emotional and material outcomes resulting from aggression. Discussion focused on the utility of assessing both moral and SIP‐related cognitions, and on the potential influence of low‐SES, high‐risk environments on these findings.  相似文献

In this paper we explore the phenomenon of writing online. We ask, 'Is writing by means of online technologies affected in a manner that differs significantly from the older technologies of pen on paper, typewriter, or even the word processor in an off-line environment?' In writing online, the author is engaged in a spatial complexity of physical, temporal, imaginal, and virtual experience: the writing space, the space of the text, cyber space, etc. At times, these may provide a conduit to a writerly understanding of human phenomena. We propose that an examination of the phenomenological features of online writing may contribute to a more pedagogically sensitive understanding of the experiences of online seminars, teaching and learning.  相似文献

Modern biological sciences require practitioners to have increasing levels of knowledge, competence, and skills in mathematics and programming. A recent review of the science curriculum at the University of Queensland, a large, research-intensive institution in Australia, resulted in the development of a more quantitatively rigorous undergraduate program. Inspired by the National Research Council''s BIO2010 report, a new interdisciplinary first-year course (SCIE1000) was created, incorporating mathematics and computer programming in the context of modern science. In this study, the perceptions of biological science students enrolled in SCIE1000 in 2008 and 2009 are measured. Analysis indicates that, as a result of taking SCIE1000, biological science students gained a positive appreciation of the importance of mathematics in their discipline. However, the data revealed that SCIE1000 did not contribute positively to gains in appreciation for computing and only slightly influenced students'' motivation to enroll in upper-level quantitative-based courses. Further comparisons between 2008 and 2009 demonstrated the positive effect of using genuine, real-world contexts to enhance student perceptions toward the relevance of mathematics. The results support the recommendation from BIO2010 that mathematics should be introduced to biology students in first-year courses using real-world examples, while challenging the benefits of introducing programming in first-year courses.  相似文献
