Teaching Patrons to Fish: The Educational Value of Cancelling Requests for Locally Available Materials

Expansive document delivery service for locally available materials is becoming increasingly popular, but is a learning component lost with the implementation of this service? In this study, the authors compare data from two institutions, one that provides an unadvertised document delivery service without instruction, and another that cancels requests for locally available materials with an instructional component. The behavior of each institution\u27s patrons over a 4-year period is analyzed and found to differ at statistically significant levels. These findings will be useful for interlibrary loan policy makers who are considering whether to implement document delivery for locally available items

Enigma of EUS: consultation on epizootic ulcerative syndrome vis-à-vis the environment and the people, 25-26 May 1992, Institute of Management in Government, Vikas Bhavan, Trivandrum 695 033, Kerala, India. Summary of proceedings

In the last two decades a serious and severely damaging fish disease has been spreading through countries of the Asia Pacific region with dangerous consequences. Not only is this disease- now officially termed Epizootic Ulcerative Syndrome (EUS)- a scientific puzzle, it is also a worrisome social problem. Hundreds of inland fishermen, often the more marginalized amongst the fishworker communities in the affected countries, have been overnight deprived of their incomes, as consumers began to totally reject the disfigured, disease-stricken fish. It was in this context that the International Collective in Support of Fishworkers (ICSF), in co-operation with the Network of Aquaculture Centres in Asia-Pacific (NACA), Bangkok, organized a two-day consultation on " EUS vis-á-vis the Environment and the People" in Trivandrum, India, during 25 and 26 May 1992. Enigma of EUS is a report of the consultation. While it does not purport to be a verbatim account of the two-day deliberations, it does record the important issues raised, the experiences exchanged and shared, and suggests how grand conclusions about as enigmatic a disease as EUS are ultimately elusive

Evaluating the Relationship Between Running Times and DNA Sequence Sizes using a Generic-Based Filtering Program.

Generic programming depends on the decomposition of programs into simpler components which may be developed separately and combined arbitrarily, subject only to well- defined interfaces. Bioinformatics deals with the application of computational techniques to data present in the Biological sciences. A genetic sequence is a succession of letters which represents the basic structure of a hypothetical DNA molecule, with the capacity to carry information. This research article studied the relationship between the running times of a generic-based filtering program and different samples of genetic sequences in an increasing order of magnitude. A graphical result was obtained to adequately depict this relationship. It was also discovered that the complexity of the generic tree program was O (log2 N). This research article provided one of the systematic approaches of generic programming to Bioinformatics, which could be instrumental in elucidating major discoveries in Bioinformatics, as regards efficient data management and analysis

Qualitative Environmental Health Research: An Analysis of the Literature, 1991-2008

BACKGROUND. Recent articles have advocated for the use of qualitative methods in environmental health research. Qualitative research uses nonnumeric data to understand people's opinions, motives, understanding, and beliefs about events or phenomena. OBJECTIVE. In this analysis of the literature, I report the use of qualitative methods and data in the study of the relationship between environmental exposures and human health. DATA SOURCES. A primary search on ISI Web of Knowledge/Web of Science for peer-reviewed journal articles dated from 1991 through 2008 included the following three terms: qualitative, environ*, and health. Inclusion and exclusion criteria are described. DATA EXTRACTION. Searches resulted in 3,155 records. Data were extracted and findings of articles analyzed to determine where and by whom qualitative environmental health research is conducted and published, the types of methods and analyses used in qualitative studies of environmental health, and the types of information qualitative data contribute to environmental health. DATA SYNTHESIS. Ninety-one articles met inclusion criteria. These articles were published in 58 different journals, with a maximum of eight for a single journal. The results highlight a diversity of disciplines and techniques among researchers who used qualitative methods to study environmental health, with most studies relying on one-on-one interviews. Details of the analyses were absent from a large number of studies. Nearly all of the studies identified increased scientific understanding of lay perceptions of environmental health exposures. DISCUSSION AND CONCLUSIONS. Qualitative data are published in traditionally quantitative environmental health studies to a limited extent. However, this analysis demonstrates the potential of qualitative data to improve understanding of complex exposure pathways, including the influence of social factors on environmental health, and health outcomes.National Institute of Environmental Health Sciences (R25 ES012084, P42ES007381

Neuropsychological Functioning of Homeless Men

Numerous biological and psychological factors associated with impaired neurological functioning have been identified as common among the homeless, but there has been relatively little systematic examination of the cognitive functioning of homeless people. This study explored the neuropsychological functioning of 90 homeless men. There was great variability in their test scores, but the presence of possible cognitive impairment was detected in 80% of the sample. Average general intellectual functioning and reading abilities were found to be relatively low, and the incidence of impairments in reading, new verbal learning, memory, and attention and concentration was high. These findings suggest that the homeless men in this study had considerable assessment and treatment needs that were not being met by most of the health and social services offered to them
