Uncovering the Evidence: Faculty Perceptions of Distance Library Services

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.     

Non‐at‐risk adolescents' attitudes towards reading in a Singapore secondary school

In this paper, we examine the various nuanced dimensions of adolescents' dispositions towards reading in one secondary school in Singapore, where a high‐stakes examination culture often threatens to colonise the practices of leisure reading. Our focus is on the better and more avid readers as they were the ones that developed the more negative attitudes towards reading at the end of their first year in secondary school. Our analysis found that there were no significant differences between boys and girls in their declining attitudes, and that for both ‘intrinsic motivation’ saw the greatest decline. However, attitudes related to learning orientation remained stable, suggesting both the impact of constraints in an exam‐oriented educational structure as well as possibilities for developing reading pedagogy and adolescent reading programmes. We argue that the more educators are aware of the multidimensionality and complexity of the attitudes and values that students bring to their reading, the more effectively they will be able to design and implement programmes and pedagogy to foster positive attitudes and promote a lifelong love for reading.     

Going to Prison: The Effect of a Prison Tour on Students’ Attitudes Toward Punitiveness

The pedagogical approaches of a criminal justice education affect the attitudes and perceptions of those most likely to develop and administer criminal justice policies in the future. This study examines the effect of a prison tour on students’ understanding of prison and attitudes about punishment. Undergraduate criminal justice students were given a survey to assess their attitudes about prisons, prisoners, and alternative sanctions before and after a field trip to the Southern Ohio Correctional Facility. Post-survey responses showed changes in students’ perceptions regarding punitiveness, prisons, prisoners, and rehabilitation. We discuss this finding within the framework of the contact hypothesis, and we recommend including this type of first-hand exposure as part of a criminal justice curriculum.

A conceptual model of taste receptors

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.     

Elastic waves in heterogeneous bars of varying cross-section

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.
