This article examines the purposes, defines the role, and analyzes the functions of a faculty field liaison. It reflects the experience of faculty members who have carried this assignment as a major responsibility. In recognition of the impact of this role on the educational process and the need for it to be clearly understood, the authors have attempted to distill its essence and to clarify the requirements for its effective practice. 相似文献

This study examined the interaction effects of the amount of practice and the cane technique used in drop-off detection with a sample of 32 adults who were blind. The advantage of the constant contact technique over the two-point touch technique was significantly greater for the less experienced cane users than for the more experienced ones. 相似文献

A growing body of research investigates the possible relationships between religion and mental health. After developing a series of arguments linking various aspects of religion with anxiety and tranquility, we test relevant hypotheses using data from the 1996 General Social Survey. Results show that frequency of religious attendance and the belief in an afterlife are inversely associated with feelings of anxiety and positively associated with feelings of tranquility. However, frequency of prayer has no direct association with either outcome. Strong beliefs in the pervasiveness of sin are positively linked with anxiety but unrelated to tranquility. Finally, belief in an afterlife and frequency of prayer buffer the adverse effects of poor health and financial decline on anxiety. Implications of these findings are discussed along with study limitations and promising directions for future research. 相似文献

By examining an online computer exchange, we find that sellers who place higher nonbinding ask prices have higher outstanding offers and remain on the exchange longer, suggesting a willingness to hold out for higher offers. Additionally, higher ask prices deter buyers from making offers. The results are stronger in thinner market segments, suggesting that gains from waiting for a high price are greater when buyers' tastes are idiosyncratic. These relationships are consistent with models in which buyers engage in costly search and suggest that online exchanges may not eliminate the frictions related to bilateral transactions. 相似文献

In this article we provide saddlepoint approximations for some important models of circular data. The particularity of these saddlepoint approximations is that they do not require solving the saddlepoint equation iteratively, so their evaluation is immediate. We first give very accurate approximations to P-values, critical values and power functions for some optimal tests regarding the concentration parameter under wrapped symmetric α-stable and circular normal models. Then, we consider an approximation to the distribution of a projection of the two-dimensional Pearson random walk with exponential step sizes. 相似文献
