Abstract Beginning in July 2002, the Health Sciences Library at the University of North Carolina at Chapel Hill underwent an 11 million dollar renovation. During three phases of the renovation, parts of the collection were inaccessible to patrons. In order to continue to make the library's collection available, library staff created a paging system. Patrons submitted requests for needed library materials using paper and electronic forms and library staff retrieved the requested items. The paging service was modified three times based on prior experience. Patrons were generally satisfied with the service. The renovation ended in December 2004. 相似文献

This study looks at 282 urban citizens' attitudes about campus dissent, attitudes about the legitimacy of a campus disturbance, and their satisfaction with a university soon after a serious campus disturbance.A majority of urban citizens were satisfied with the university. Their beliefs about the university were heavily related to their satisfaction. Younger, more educated citizens, as well as those with more university-related experiences and those with more positive attitudes about campus freedom of expression, have more positive attitudes about campus dissent. Most urban citizens did not consider the campus disturbance to be a legitimate form of social protest. Urban citizens with more positive attitudes about campus dissent and those who did not believe that many subversive activities were going on at the university were more apt to view the disturbance as a legitimate form of social protest. 相似文献

This study describes job activities, role expectations, and jobs satisfactions of academic advisers. The sample consisted of 452 faculty and staff academic advisers in five colleges at the University of Minnesota (Twin Cities). Seventy-two percent of the sample completed the questionnaire. The work of the academic adviser can be classified into four clusters of job activities. Three involve helping students: (1) with special academic, social, or financial problems, (2) with emotional or psychological problems, and (3) with academic and career guidance problems. The fourth involves administrative activities. Results from this study also suggest that advisers spend most of their time approving registration cards and providing information about academic requirements. Most advisers view themselves as appropriate sources of help in academic and vocational guidance areas rather than in personal or social ones. In general, most academic advisers are satisfied with their work as an adviser. A substantial percentage is dissatisfied with the amount of recognition they receive. Finally, those advisers with more advanced degrees and those with larger numbers of advisees tend to be more dissatisfied. 相似文献

Liver fibrosis is the end-stage of many chronic liver diseases and is a significant health threat. The only effective therapy is liver transplantation, which still has many problems, including the lack of donor sources, immunological rejection, and high surgery costs, among others. However, the use of cell therapy is becoming more prevalent, and mesenchymal stem cells (MSCs) seem to be a promising cell type for the treatment of liver fibrosis. MSCs have multiple differentiation abilities, allowing them to migrate directly into injured tissue and differentiate into hepatocyte-like cells. Additionally, MSCs can release various growth factors and cytokines to increase hepatocyte regeneration, regress liver fibrosis, and regulate inflammation and immune responses. In this review, we summarize the current uses of MSC therapies for liver fibrosis and suggest potential future applications. 相似文献

We study the structure of the interregional inventor networks in Sweden by examining the residence of inventors and coinventors involved in Swedish patent applications to the European Patent Office. Several factors are found to influence the spatial affinity of regions. We find that spatial affinity extends beyond the region if it has less own R&D-related resources (business R&D, university R&D and patenting); if it is close to the other region and if it is relatively small. The resources of that other region plays a positive role if, in analogue fashion, that region has more R&D-related resources. 相似文献

Preserving the Past: An Early Interview Improves Delayed Event Memory in Children With Intellectual Disabilities 下载免费PDF全文
The influence of an early interview on children's (N = 194) later recall of an experienced event was examined in children with mild and moderate intellectual disabilities (CWID; 7–12 years) and typically developing (TD) children matched for chronological (7–12 years) or mental (4–9 years) age. Children previously interviewed were more informative, more accurate, and less suggestible. CWID (mild) recalled as much information as TD mental age matches, and were as accurate as TD chronological age matches. CWID (moderate) recalled less than TD mental age matches but were as accurate. Interviewers should elicit CWID's recall as early as possible and consider developmental level and severity of impairments when evaluating eyewitness testimony. 相似文献

Stem cells can be obtained from women’s menstrual blood derived from the endometrium. The cells display stem cell markers
such as Oct-4, SSEA-4, Nanog, and c-kit (CD117), and have the potent ability to differentiate into various cell types, including
the heart, nerve, bone, cartilage, and fat. There has been no evidence of teratoma, ectopic formation, or any immune response
after transplantation into an animal model. These cells quickly regenerate after menstruation and secrete many growth factors
to display recurrent angiogenesis. The plasticity and safety of the acquired cells have been demonstrated in many studies.
Menstrual blood-derived stem cells (MenSCs) provide an alternative source of adult stem cells for research and application
in regenerative medicine. Here we summarize the multipotent properties and the plasticities of MenSCs and other endometrial
stem cells from recent studies conducted both in vitro and in vivo. 相似文献

Anatomical examinations have been designed to assess topographical and/or applied knowledge of anatomy with or without the inclusion of visual resources such as cadaveric specimens or images, radiological images, and/or clinical photographs. Multimedia learning theories have advanced the understanding of how words and images are processed during learning. However, the evidence of the impact of including anatomical and radiological images within written assessments is sparse. This study investigates the impact of including images within clinically oriented single-best-answer questions on students' scores in a tailored online tool. Second-year medical students (n = 174) from six schools in the United Kingdom participated voluntarily in the examination, and 55 students provided free-text comments which were thematically analyzed. All questions were categorized as to whether their stimulus format was purely textual or included an associated image. The type (anatomical and radiological image) and deep structure of images (question referring to a bone or soft tissue on the image) were taken into consideration. Students scored significantly better on questions with images compared to questions without images (P < 0.001), and on questions referring to bones than to soft tissue (P < 0.001), but no difference was found in their performance on anatomical and radiological image questions. The coding highlighted areas of “test applicability” and “challenges faced by the students.” In conclusion, images are critical in medical practice for investigating a patient's anatomy, and this study sets out a way to understand the effects of images on students' performance and their views in commonly employed written assessments. 相似文献
