[目的/意义]信息资源发现与传递服务一直是图书馆的核心业务,目前在欧美出现一种新形式即基于Bento模式的联邦检索服务系统,研究其最新发展趋势对完善我国图书馆发现系统有重要参考价值。[方法/过程]通过文献调查、比较研究、案例分析等方法,对比国内外发展现状,揭示混合排序的不足和Bento模式的优点,并以美国伊利诺大学香槟分校(UIUC)图书馆为例说明其应用和未来发展趋势。[结果/结论]实践证明Bento模式更有利于实现从全资源发现向全图书馆发现的转变,检索效果和图书资源利用率均有较大幅度的提升。 相似文献

This study examined the rates of special education placement during middle school grades (sixth through eighth) among children who participated in the Linda Ray Intervention Program (LRIP) center-based and home-based learning modalities. The study sample included 113 children in Miami Dade County Public Schools who had gestational cocaine exposure and received early intervention services due to developmental delays. This study found that children who participated in the center-based (25 hours per week) learning modality had a significantly lower rate of special education placement (14%) than the students in the home-based (three hours per week) learning modality (30%) in middle school. Also, results indicated that children who were socioeconomically disadvantaged (free/reduced lunch) and in the home-based learning modality were three to four times more likely to be in special education. This study provides evidence for the long-term impact of the LRIP center-based modality on special education outcomes. 相似文献

Counselling for work and relationship is proposed as another way of thinking about vocational psychology and vocational guidance. It can contribute to the search for a new paradigm for these fields. Central to this way of thinking are two shifts. A shift from a discourse about career to a discourse about work, and a shift to expand the focus of attention beyond the occupational domain to include multiple social contexts of work and relationship across both occupational and personal domains of life. The ways in which these shifts are responsive to theoretical and social contexts is considered. 相似文献

Among the initiatives of the Maryland Collaborative for Teacher Preparation (MCTP) is a summer research internship program
that places preservice middle grades teachers in extended collaboration with professional mathematicians, scientists, and
educators engaged in research and curriculum development activities. We describe the MCTP internship program including the
rationale for and structural features of the program. We also highlight the effects of the internship experience on preservice
teachers' conceptions of and beliefs about the nature and processes of mathematics and science, and the teaching of mathematics
and science. Our findings suggest that the internship experience is a fundamentally significant life experience for preservice
teachers. Furthermore, internships have the potential for realizing reform in mathematics and science education; that is,
preservice teachers who have participated in MCTP internships intend to bring a holistic, conceptually oriented view of mathematics
and science to their classrooms. The paper concludes with a summary of ongoing programmatic and logistical challenges of the
MCTP internship program.

The effect of differential outcome expectancies on memory for temporal and nontemporal information was examined. Pigeons were trained to match short (2-sec) and long (8-sec) sample durations to red and green comparison stimuli, and vertical and horizontal lines to vertical and horizontal comparison stimuli. In Experiment 1, one differential outcome (DO) group received food for correct choices on short-sample trials, whereas another received food for correct choices on long-sample trials. On line-orientation trials, half of each DO group received food for correct responses following vertical samples, whereas the other half received food for correct responses following horizontal samples. Overall retention was greater in the DO groups than in a nondifferential (NDO) group that received either food or no food for correct responses on a random half of all trials. Furthermore, although the NDO group displayed a choose-short bias for temporal samples, both DO groups displayed equivalent biases to select the comparison stimulus associated with food. In Experiment 2, differential outcome expectancies were extinguished off-baseline. Subsequently, in the first nondifferential outcome test session, the. DO groups performed less, accurately than the NDO group. These findings indicate that temporal samples are not retrospectively and analogically coded when they are differentially associated with food and no food. Instead, they are remembered in terms of the corresponding outcome expectancies. 相似文献

This article presents an exploration of a group of Early Years Practitioners’ (EYPs) perceptions of gender that may provide some insight into the growing divide between boys’ and girls’ educational performance [Burusic, J., T. Babarovic, and M. Seric. 2012. “Differences in Elementary School Achievement between Girls and Boys: Does the Teacher’s Gender Play a Role?” European Journal of Psychology of Education 27 (4): 523–538]. I argue that the current media and educational interest in the gendered brain [Sax, L. 2005. Why Gender Matters: What Parents and Teachers Need to Know About the Emerging Science of Sex Differences. New York: Broadway Books] and the influences that surround the child [Eckert, P., and G. S. McConnell. 2013. Language and Gender. 2nd ed. Cambridge: Cambridge University Press], can result in children acquiring social expectations and attitudes to learning that are different for both sexes. The frequent dimorphic treatment of boys and girls is often based on assumed biological differences [Baron-Cohen, S., S. Lutchmaya, and R. Knickmeyer. 2004. Prenatal Testosterone in Mind: Amniotic Fluids Studies. Massachusetts Institute of Technology] that suggest that the sexes learn differently. This can result in the approaches to the care and education of children being established on their sex categories rather than their individual needs. My focus here is to explore practitioners’ expectations and understanding of children’s behaviour and learning in the nursery environment. The study is premised on the belief that practitioners’ perceptions of gender could, as argued by [Eliot, L. 2009. Pink Brain, Blue Brain: How Small Differences Grow into Troublesome Gaps – And what we can do About It. New York: Houghton Mifflin Harcourt Publishing Company], result in self-fulfilling prophecies being (re)produced and (re)created. The deployment of stereotypical assumptions and practices could, I suggest, limit children’s opportunities. The data used here are drawn from my doctoral study of the nature of gender as was understood by eight EYPs who took part in five discussion group sessions. An interpretative paradigm was adopted, where the EYPs’ discussed their experiences and understanding of gender from their practice. Following [Holloway, I., and S. Wheeler. 2013. Qualitative Research in Nursing and Healthcare. 3rd ed. West Sussex: John Wiley &; Sons Limited], the study explored experiences and perceptions in order to illuminate meaning and understanding. The findings indicated that there is a belief amongst the group of practitioners with whom I worked that gender is either innate or learned and that EYPs play no role in its development. The tentative conclusions suggest that changes to the education and training of EYPs are required in order to raise awareness of gender issues in nurseries. I suggest that there is a need to place gender back on the education and training agenda for EYP in order to support changes to practice that could, in turn, provide children with more equitable teaching and learning experiences. 相似文献
