Working memory training improves children's cognitive performance on untrained tasks; however, little is known about the underlying neural mechanisms. This was investigated in 32 typically developing children aged 10–14 years (19 girls and 13 boys) using a randomized controlled design and multi-modal magnetic resonance imaging (Devon, UK; 2015–2016). Training improved working memory performance and increased intrinsic functional connectivity between the bilateral intraparietal sulci. Furthermore, improvements in working memory were associated with greater recruitment of the left middle frontal gyrus on a complex span task. Repeated engagement of fronto-parietal regions during training may increase their activity and functional connectivity over time, affording greater working memory performance. The plausibility of generalizable cognitive benefits from a neurobiological perspective and implications for neurodevelopmental theory are discussed. 相似文献

AbstractCarnosine was originally discovered in skeletal muscle, where it exists in larger amounts than in other tissues. The majority of research into the physiological roles of carnosine have been conducted on skeletal muscle. Given this and the potential for muscle carnosine content to be increased with supplementation, there is now a large body of research examining the ergogenic effects (or otherwise) of carnosine. More recent research, however, points towards a potential for carnosine to exert a wider range of physiological effects in other tissues, including the brain, heart, pancreas, kidney and cancer cells. Taken together, this is suggestive of a potential for carnosine to have therapeutic benefits in health and disease, although this is by no means without complication. Herein, we will provide a review of the current literature relating to the potential therapeutic effects of carnosine in health and disease. 相似文献

One of the highest priorities in today's hospitals is the provision of quality care to patients. The medical librarian has an increased responsibility to furnish quality information to the medical staff. Traditional methods of reference service continue to work well, but it is increasingly important for librarians to become more directly involved in hospital quality assurance (QA) activities. Occurrence screening is one system of QA where the librarian can make a difference. 相似文献

Drawing on components of agenda-setting theory and the two-step flow of information from mass media to news audiences, this study examines the effects of mass and interpersonal communication on breast cancer screening practices among college- and middle-aged women (n = 284). We theorized that screening behaviors among younger women would be influenced more by interpersonal sources of information while screening among middle-aged women would be more influenced by exposure to mass-mediated information. Findings supported anticipated patterns, revealing important and varying roles for both mass and interpersonal communication in the health behaviors of women. Implications for health practitioners and campaign planners, as well as recommendations for future research, are discussed. 相似文献

This article explores the evolution of the role of academic journal articles submitted to the UK's Research Assessment Exercise (RAE). By reviewing their role, it is possible to see how the changes from quantitative to qualitative assessment (and the resulting problems surrounding the definition of ‘quality’ journals) has impacted both on the journals selected by academics for publishing their research and the assessment of them. Although only one part of RAE submissions, the listing of published research outputs provides the primary evidence for research quality to most RAE panels, and is a significant driver of the final grade awarded, and thus the funding received by submitting institutions. The RAE, being a peer‐reviewed assessment exercise, mirrors in some ways the peer‐review process immured within scholarly publication. The developing role of journal publications as a vehicle for academic research output is examined via the chronology of the RAE, before assessing the current situation in which published journal output formed almost 70% of all output assessed by RAE panels in the latest exercise. The impact of this increased importance of academic journals in the assessment process is considered not only for academics but also for the wider community, i.e. publishers and libraries. 相似文献

As academic libraries' budgets remain flat while their expenditures rise, library leaders must seek out alternative sources of funding. One option is a mandatory student fee dedicated to the library. This article presents the results of a survey of 152 deans and directors of public R1 and R2 research universities that were asked whether their libraries benefit from mandatory student fees. While a library-specific fee is unusual, nearly half of responding libraries are eligible to receive some portion of another mandatory student fee. Study results can serve as evidence for libraries preparing to make a case for the significant, positive impact possible through even a modest library fee. 相似文献
