Library support for science research and education at Bucknell University: pulling it all together

Based on the Ricker/Witmer survey on Library Support for Science Research and Education, a brief statistical analysis of the Bucknell University community and library support for science and engineering research and education is provided. The position and responsibilities of Reference Librarian/Coordinator of Science and Engineering Resources in the Ellen Clarke Bertrand Library are detailed. Throughout the article, I describe the motivation and justification for an integrated university library collection, which serves not only the Science and Engineering faculty and students, but the entire Bucknell University community. The issues of finance and budget, public service, and information access and delivery in relation to a central university library are discussed.

Overview of literature and information on "khat-related" mortality: a call for recognition of the issue and further research

During the past 20 years or so, more has become known about the properties of khat, its pharmacology, physiological and psychological effects on humans. However, at the same time its reputation of social and recreational use in traditional contexts has hindered the dissemination of knowledge about its detrimental effects in terms of mortality. This paper focuses on this particular deficit and adds to the knowledge-base by reviewing the scant literature that does exist on mortality associated with the trade and use of khat. We sought all peer-reviewed papers relating to deaths associated with khat. From an initial list of 111, we identified 15 items meeting our selection criteria. Examination of these revealed 61 further relevant items. These were supplemented with published reports, newspaper and other media reports. A conceptual framework was then developed for classifying mortality associated with each stage of the plant's journey from its cultivation, transportation, consumption, to its effects on the human body. The model is demonstrated with concrete examples drawn from the above sources. These highlight a number of issues for which more substantive statistical data are needed, including population-based studies of the physiological and psychological determinants of khat-related fatalities. Khat-consuming communities, and health professionals charged with their care should be more aware of the physiological and psychological effects of khat, together with the risks for morbidity and mortality associated with its use. There is also a need for information to be collected at international and national levels on other causes of death associated with khat cultivation, transportation, and trade. Both these dimensions need to be understood.

Transnationalism and Identity: the Concept of Community in Ghanaian Literature and Contemporary Ghanaian Culture

In my thesis, I use anthropology, literature, and adinkra, an indigenous art, to study Ghanaian concepts of community from an interactive standpoint. While each of these disciplines has individually been used to study the concept of community, the three have not previously been discussed in relation to one another. I explore the major findings of each field—mainly that in anthropology, transnational informants find communities upheld; in literature, transnational characters find the opposite; and in adinkra, there are elements of both continuity and dissolution—to discuss Ghanaian constructs of community in the transnational world. Throughout time, there have always been transnational individuals and concepts, but as globalization continues, transnationalism has become an ever-more vital topic, and combined with the common anthropological discussion of tradition and modernity, its influence on developing countries, like Ghana, is significant. Therefore, in my thesis, I explore how differing conceptions of community present themselves in each discipline, and how those divergences create a new understanding of place and identity.

Design Simulation for Solar Energy Research and Education

Solar research is primarily conducted in regions with consistent sunlight, severely limiting research opportunities in many areas. Unfortunately, the unreliable weather in Lewisburg, PA, can prove difficult for such testing to be conducted. As such, a solar simulator was developed for educational purposes for the Mechanical Engineering department at Bucknell University. The objective of this work was to first develop a geometric model to evaluate a one sun solar simulator. This was intended to provide a simplified model that could be used without the necessity of expensive software. This model was originally intended to be validated experimentally, but instead was done using a proven ray tracing program, TracePro. Analyses with the geometrical model and TracePro demonstrated the influence the geometrical properties had results, specifically the reflector (aperture) diameter and the rim angle. Subsequently, the two were approaches were consistent with one another for aperture diameters 0.5 m and larger, and for rim angles larger than 45°. The constructed prototype, that is currently untested, was designed from information provided by the geometric model, includes a metal halide lamp with a 9.5 mm arc diameter and parabolic reflector with an aperture diameter of 0.631 meters. The maximum angular divergence from the geometrical model was predicted to be 30 mRadians. The average angular divergence in TraceProof the system was 19.5 mRadians, compared to the sun’s divergence of 9.2 mRadians. Flux mapping in TracePro showed an intensity of 1000 W/m2 over the target plane located 40 meters from the lamp. The error between spectrum of the metal halide lamp and the solar spectrum was 10.9%, which was found by comparing their respective Plank radiation distributions. The project did not satisfy the original goal of matching the angular divergence of sunlight, although the system could still to be used for optical testing. The geometric model indicated performance in this area could be improved by increasing the diameter of the reflector, as well as decreasing the source diameter. Although ray tracing software provides more information to analyze the simulator system, the geometrical model is adequate to provide enough information to design a system.

Service Use and Mental Impairment Among the Elderly: Arguments for Consultation and Education

Compared the service use patterns of older adults with varying levels of mental impairment, and assessed the effects of services received on their mental health status over a 1-yr period. Data were obtained from a US General Accounting Office (1977, 1979) study of 531 elderly persons (mean age 76.1 yrs), which included administration of a modified version of the Older Americans Resources and Services Multidimensional Functional Assessment Questionnaire. Ss were interviewed twice, 1 yr apart. 174 Ss were classified as having a mild psychiatric impairment, and 118 Ss had a severe psychiatric impairment. The existence of mental impairment was related to marital status, race, and level of education. Usage of mental health services was low, although mentally impaired Ss were more likely than unimpaired Ss to use social and medical services. Results also suggest that such services can have an important effect on the mental health of older persons.
