The Medical Library Association''s InSight Initiative provides an open and collaborative environment for library and industry partners to discuss vexing problems and find solutions to better serve their users. The initiative''s fifth summit, continuing work from the previous summit, focused on understanding how users discover and access information in the clinical environment. During the summit, participants were divided into working groups and encouraged to create a tangible product as a result of their discussions. At the end of the summit, participants established a framework for understanding users'' pain points, discussed possible solutions to those points, and received feedback on their work from an End User Advisory Board comprising physicians, clinical researchers, and clinical faculty in biomedicine. In addition to the pain point framework, participants are developing MLA InSight Initiative Learning content with modules to educate librarians and publishers about critical aspects of user behavior. The 2020 Insight Initiative Fall Forum will serve as a virtual home for constructive dialogue between health sciences librarians and publishers on improving discovery and access to information. 相似文献

ABSTRACT This study examined the simultaneous effects of relative age and biological maturity status upon player selection in an English professional soccer academy. A total of 202 players from the U9 to U16 age groups, over an eight-year period (total of 566 observations), had their relative age (birth quarter) and biological maturity (categorised as late, on-time or early maturing based upon the Khamis-Roche method of percentage of predicted adult height at time of observation) recorded. Players born in the first birth quarter of the year (54.8%) were over-represented across all age groups. A selection bias towards players advanced in maturity status for chronological age emerged in U12 players and increased with age; 0% of players in the U15 and U16 age group were categorised as late maturing. A clear maturity selection bias for early maturing players was, however, only apparent when the least conservative criterion for estimating maturity status was applied (53.8% early and 1.9% late maturing in the U16 age group). Professional football academies need to recognise relative age and maturation as independent constructs that exist and operate independently. Thus, separate strategies should perhaps be designed to address the respective selection biases, to better identify, retain and develop players. 相似文献

Does Schooling Buffer the Effects of Early Risk? 总被引:1,自引:0,他引:1
The data presented here come from a 20-year study conducted in a rural area of Guatemala. Data on early biological indicators, graduated parameters of social structure, and preschool cognition were combined into a risk scale and analyzed in relation to primary school grade attainment and adolescent psychoeducational test performance. Similar to empirical relations reported in industrialized countries, performance declined as the number of risk factors to which a subject was exposed increased. More important, primary education was observed to buffer the effects of early risk for a subset of subjects. Subjects at high risk who stayed in school performed significantly better than subjects with similar levels of risk who completed fewer than 4 years of primary school. 相似文献
