Are We Spending Too Much on Print STEM Monographs? A Method and Analysis for Improving Monograph Allocations Based on Circulation Statistics

Circulation studies provide evidence of demand for monographs, but it is necessary to determine the goal of any analysis in order to select which statistics will be used. The goal of this analysis was to determine the appropriateness of expenditures on monographs within the STEM fields at Morris Library over a ten-year period. Percentage of unique title circulation and average circulation per title are best suited for this purpose. Results show variation among discplines, but over-expenditure in all. Analysis of disciplines can aid in determining appropriate allocations for monographs, and analysis of subdisciplines can aid in targeting monograph acquisitions within any discipline

The DEAD-box protein MEL-46 is required in the germ line of the nematode Caenorhabditis elegans

Background: In the hermaphrodite of the nematode Caenorhabditis elegans, the first germ cells differentiate as sperm. Later the germ line switches to the production of oocytes. This process requires the activity of a genetic regulatory network that includes among others the fem, fog and mog genes. The function of some of these genes is germline specific while others also act in somatic tissues. DEAD box proteins have been shown to be involved in the control of gene expression at different steps such as transcription and pre-mRNA processing.Results: We show that the Caenorhabditis elegans gene mel-46 (maternal effect lethal) encodes a DEAD box protein that is related to the mammalian DDX20/Gemin3/DP103 genes. mel-46 is expressed throughout development and mutations in mel-46 display defects at multiple developmental stages. Here we focus on the role of mel-46 in the hermaphrodite germ line. mel-46(yt5) mutant hermaphrodites are partially penetrant sterile and fully penetrant maternal effect lethal. The germ line of mutants shows variable defects in oogenesis. Further, mel-46(yt5) suppresses the complete feminization caused by mutations in fog-2 and fem-3, two genes that are at the top and the center, respectively, of the genetic germline sex determining cascade, but not fog-1 that is at the bottom of this cascade.Conclusion: The C. elegans gene mel-46 encodes a DEAD box protein that is required maternally for early embryogenesis and zygotically for postembryonic development. In the germ line, it is required for proper oogenesis. Although it interacts genetically with genes of the germline sex determination machinery its primary function appears to be in oocyte differentiation rather than sex determination

Technical Communication Academic Program Review

This report summarizes an evaluation of the UNT Libraries' Technical Communication-related resources and materials to determine if the collection is adequately serving patron needs. It was generated as part of the UNT Libraries’ contributions to the university’s Academic Program Reviews, which are conducted by the Accreditation office in the Division of Planning. The UNT Libraries’ Collection Assessment Department evaluated collections’ ability to meet the curricular and research needs of the academic programs being reviewed. They assessed current needs based on course descriptions and research outputs, defined the scope of information needed based on this needs assessment, and evaluated the Libraries’ holdings in these subject areas against the usage, qualitative listings, and requests for materials from other libraries. Specific recommendations for collection development are provided based on the results of these analyses

АНАЛІЗ ЗАКОНОМІРНОСТІ ПОШИРЕННЯ ЗАХВОРЮВАНЬ МЕТОДОМ МАТЕМАТИЧНОЇ СТАТИСТИКИ

Робота присвячена теоретичному аналізу існуючих моделей розвитку популяцій з метою визначення моделі динаміку розвитку захворювань. Проведено аналіз захворювань на грип та ГРВЗ в двох селах Херсонської області. Отримано умови зниження захворювань і зменшення економічних витрат. Для зниження кількості захворювань необхідно знизити фактор, який викликає захворювання, то необхідно, щоб β, при цьому економічні витрати можуть зростати, тому для оптимізації економічних витрат необхідно досягти мінімуму функції, які їх описує. Проведено статистичний аналіз і теоретичне моделювання розвитку неінфекційних захворювань
