Improving GIS Consultations： A Case Study at Yale University Library     

张文德 《数字图书馆论坛》2006,(12):77-77

面向服务的体系结构、对等网络和网格技术的发展为数宇图书馆体系结构的研究和应用带来了新的机遇，使其在开放性和柔性方面的拓展成为可能。下一代数字图书馆应当是能为更多用户服务的、自适性更强的服务组织，它是以联邦模式进行资源库的构建和服务的组织。与传统数字图书馆相比，下一代数字图书馆的体系结构将更为分布和动态，从而适应资源库、元数据和服务所呈现出的高度异构性。  相似文献   

Preparing for Practice: Strengthening Third-Year Medical Students’ Awareness of Point-of-Care Resources     

Tamara M. Nelson 《Medical reference services quarterly》2018,37(3):312-318

This column describes the development and implementation of a responsive library course designed to train third-year medical students as they begin their clerkships. The course design consisted of a brief face-to-face introduction during third-year orientation and an online course developed in Canvas, an online learning management system. The objective of the course was to not only introduce students to the resources but also to teach them how to effectively use those resources at the point-of-care. Students evaluated the course to assess the overall effectiveness of the instruction. Course development and content, feedback provided by students, as well as suggestions for improvement are discussed.  相似文献   

Could scientists use Altmetric.com scores to predict longer term citation counts?     

Mike Thelwall  Tamara Nevill 《Journal of Informetrics》2018,12(1):237-248

Altmetrics from Altmetric.com are widely used by publishers and researchers to give earlier evidence of attention than citation counts. This article assesses whether Altmetric.com scores are reliable early indicators of likely future impact and whether they may also reflect non-scholarly impacts. A preliminary factor analysis suggests that the main altmetric indicator of scholarly impact is Mendeley reader counts, with weaker news, informational and social network discussion/promotion dimensions in some fields. Based on a regression analysis of Altmetric.com data from November 2015 and Scopus citation counts from October 2017 for articles in 30 narrow fields, only Mendeley reader counts are consistent predictors of future citation impact. Most other Altmetric.com scores can help predict future impact in some fields. Overall, the results confirm that early Altmetric.com scores can predict later citation counts, although less well than journal impact factors, and the optimal strategy is to consider both Altmetric.com scores and journal impact factors. Altmetric.com scores can also reflect dimensions of non-scholarly impact in some fields.  相似文献

‘Fractured communities’: uncertainty,stress, and (a lack of) communal coping in Palestinian refugee camps     

Tamara D. Afifi  Walid A. Afifi  Anne F. Merrill  Najib Nimah 《Journal of Applied Communication Research》2016,44(4):343-361

This study examined how communal coping reveals itself in Palestinian refugee camps and the conditions that promote or prevent its occurrence. Individual and dyadic interviews were conducted with 40 mothers and one of their adolescent children living in Palestinian refugee camps in Lebanon. The results revealed that communal coping existed within the mother–adolescent dyad to a certain extent, but was rare within the larger context of the refugee camps. While families and neighbors did not typically verbalize their hardships and actively cope with them as a group, there was often an implicit recognition that they were all experiencing the same uncertainty and stress. Acting upon their uncertainty as a collective, however, was greatly hampered by mistrust within and outside the camps, due to widespread violence, privacy violations, vying for scarce resources, and disloyalty. Parents and adolescents also engaged in protective buffering whereby they attempted to reduce the stress of the family by keeping stress and fears to themselves rather than communicating about them. Even though protective buffering helped the refugees cope with chronic uncertainty and maintain a sense of normalcy, it prevented them from acting upon the problem as a group. Finally, parents emphasized that the child’s education provided hope for the future. Practical implications are discussed.  相似文献

The questionable role of higher education as an occupational screening device     

Abraham E. Haspel 《Higher Education》1978,7(3):279-294

Employers optimally pursue activities which facilitate the coordinating of employee characteristics and the requirements of the job. One allegedly important employee characteristic is the level of education. Employees with higher levels of education are rewarded with higher wages than employees with lower levels. This may occur if higher levels of education make an employee truly more productive or if because of an employer's beliefs only those individuals with higher levels of education are allowed to enter the higher paying positions (occupational screening).The above propositions are testable, depending crucially upon the theoretical model employed for determining occupational choices. We shall compare the implications of two possible occupation choice models: (1) enter the job which offers the highest lifetime income, (2) enter the job which offers the highest level of overall satisfaction. We estimate these two models using the NBER-TH data sample. By distributing our estimated results and the actual distribution of occupations over the education levels of high school, some college and BA we can see if more or less people are expected to enter specific occupations at each education level. Support for screening exists if more people are expected in high status occupations at low education levels than are actually in those occupations.When comparing the estimated results for each model we see different outcomes emerge. The latter indicates that screening does not exist while the former does. We present arguments as to why we feel that the second model is the more correct and appropriate and, consequently, why we feel that education is not an effective screening device.  相似文献   

The necessity of each phase of the learning cycle in teaching high school physics     

John W. Renner  Michael R. Abraham  Howard H. Birnie 《科学教学研究杂志》1988,25(1):39-58

The learning cycle is a method of teaching—it is also a curriculum organization principle and is derived directly from the mental functioning model invented by Piaget. Although Jean Piaget contributed to the formation of the learning cycle (Piaget, 1973), its present structure has to be attributed to Dr. Robert Karplus and the persons who developed the materials of the Science Curriculum Improvement Study (SCIS). It was through the SCIS activities that many of us learned how to develop curricula and teach with the learning cycle. The learning cycle is built upon the premise that three distinct phases are necessary in developing understanding of a concept, that those phases have a definite sequence, and each phase has a definite structure or form. The research done in testing the form variable has already been reported in this journal (Renner, Abraham, & Birnie, 1985). This report explores whether or not each learning-cycle phase is necessary in learning a concept.  相似文献
