The issue of format duplication in academic library collections is increasingly complicated and perplexing in an environment of static or dwindling resources, soaring user expectations, dynamic access models, and inconsistent and changing publisher and vendor pricing structures. The problem is further complicated for libraries serving a university with multiple campus locations. This paper surveys recent investigative projects and highlights the work of a Duplicate Formats Task Force at Pennsylvania State University charged with determining the extent and nature of format duplication at that institution. 相似文献

Prospective application of serum cytokines, lipopolysaccharide (LPS), and heat shock proteins (eHSPs) requires reliable measurement of these biomarkers that can signify exercise-induced heat stress in hot conditions. To accomplish this, both short-term (7 day) reliability (at rest, n = 12) and the acute responsiveness of each biomarker to exercise in the heat (pre and post 60-min cycling, 34.5°C and 70% RH, n = 20) were evaluated. Serum was analysed for the concentration of C-reactive protein (CRP), interleukin-6 (IL-6), heat shock protein 72 (eHSP72), immunoglobulin M (IgM) and LPS. Test–retest reliability was determined as the coefficient of variation (CV). Biomarkers with the least short-term within-participant variation were IL-6 (19%, ±20%; CV, ±95% confidence limits (CL)) and LPS (23%, ±13%). Greater variability was observed for IgM, eHSP72 and CRP (CV range 28–38%). IL-6 exhibited the largest increase in response to acute exercise (95%, ±11%, P = < 0.001) and although CRP had a modest CV (12%, ±7%), it increased substantially post-exercise (P = 0.02, ES; 0.78). In contrast, eHSP72 and LPS exhibited trivial changes post-exercise. It appears variation of common inflammatory markers after exercise in the heat is not always discernible from short-term (weekly) variation. 相似文献

In a scientific dispute over the effects of atrazine on amphibians, chemical industry–funded and publically funded scientists present stunningly contrasting constructions of atrazine's environmental concentrations, persistence, and potential to harm. Considerable scientific uncertainties and variable ranges allow authors to construct preferred versions of the story of atrazine. These incommensurate rhetorical constructions, more the result of competing economic and environmental interests than of any paradigmatic misalignments, have prolonged the dispute not only over atrazine's effects but also over whether its sales should be banned. 相似文献
