Usage statistics are a regular part of assessment but the lack of context leaves librarians pondering the reasons for fluctuations in use. Through development of an online survey, we examined faculty perceptions, knowledge, and use of distance library services to support online courses. Responses provided much needed context and helped to determine priorities and direction for services. While this survey was a useful marketing tool, results emphasized that the greatest need was for ongoing communication with faculty to increase awareness of services provided.  相似文献

This paper presents research findings on childrens’ responses to migratory separation and later reunion in Caribbean families and the needs of these families when parents migrate and leave their children behind. Implications of this type of separation on children, parents and surrogate caregivers are discussed. The challenges that counsellors in both the ‘sending’ and host countries face working with this population are also examined and suggestions made for psychosocial intervention and guidelines for counselling in both societies. The need for culturally competent counsellors to work with the growing population of immigrants in North America and Europe is indicated.  相似文献

Of all the senses, that of taste is perhaps the hardest to define and quantify and elucidation of the underlying mechanisms is unrespondingly difficult. This article describes a conceptual model — at the molecular level — for the four basic taste modalities, using apparent specific volume as a fundamental parameter. It also considers possible practical applications.  相似文献

The propagation of elastic waves in a heterogeneous bar of variable cross-sectional area is investigated via use of the method of characteristics andthe Laplace transform technique. The Young's modulus and density are assumed to be representable as either power law or exponential distributions in the axial coordinate. The transform method is used to establish an infinite number of multi-parameter solutions in closed form for either a stress, velocity or displacement type boundary condition. The numerical characteristic computations show excellent agreement when compared to the transform solutions, and are then used to obtain additional solutions not attainable by the transform method. Detailed results and conclusions for a bar of ogival cross-section are given for a wide range of inhomogeneity.  相似文献

To investigate how source of event information influences children's event representations, 5- and 6-year-old children were exposed to a novel event through direct experience, observation, or a story. 2 of the 4 scenes comprising the event contained actions that were logically organized, and the remaining 2 scenes contained actions that were arbitrary in their organization. Children received either 1 or 3 exposures to the event. For children receiving multiple exposures, 2 scenes contained actions that varied across exposures. A few days following their last exposure, children were asked to verbally recall and reenact the event. Reports were generally more complete, organized, and accurate when the event was directly experienced compared to when it was observed or heard about through a story. However, the impact of information source interacted with interview (recall, reenactment) and number of event exposures. Furthermore, children's sensitivity to event structure was dependent on information source and exposure. These results highlight the importance of information source in the formation of children's event representations.  相似文献

A bstract .  In this essay, Mordechai Gordon explores the significance of Rilke's challenge to "live the questions" and embrace uncertainty with respect to the quest for certainty in education. The quest for certainty in education refers to our desire to gain a sense of psychological security and more control over a field that is fundamentally indeterminate. This quest implies an unwillingness to live with the inherent complexities and risks of education. After exploring the meaning and import of Rilke's challenge and comparing it to the position of Socrates, Gordon uses Rilke's insight to analyze a specific educational experience and then discusses some of its educational implications for teacher education.  相似文献
