Abstract. Professors are often displeased with the research and synthesis of thought demonstrated in many of their students' research papers. One way to address this problem is by rewording assignments to encourage critical thinking. By reworking traditional research assignments to reflect the five information-literacy skills developed by the Association of College and Research Libraries, instructors can guide students through the research process in ways that actively develop critical thought processes.  相似文献

Edwin Mansfield’s contributions to the economics of technology are summarized from the early 1960s through his death in 1997. Mansfield’s methodology is discussed, as are his contributions on: the diffusion of technical innovation, the effect of firm size on innovation, the role of academic and basic research in increasing innovation and productivity, international technology transfer and the inaccuracy of technological forecasts. The economics profession’s evaluation of the relative importance of Mansfield’s work is presented, using as evidence citation counts of his works collected from the Social Science Citation Index (SSCI). Identified as among Mansfield’s most important contributions are his work on the importance of academic research for industrial innovations, his empirical estimation of the rates of diffusion of different innovations, and his estimation of the private and social returns from investments in industrial innovations. Finally, we present Mansfield’s advice on the future of the economics of technology.  相似文献

There are concerns among healthcare practitioners about poor anatomical knowledge among recent healthcare graduates. Universal Design for Learning (UDL) is a framework developed to enhance students' experience of learning and help students to become motivated learners. This scoping review identified whether UDL has been utilized in third level healthcare education and if so, whether it had been used to enhance student motivation to study anatomy. Seven online databases were searched for studies reporting the use of UDL in the curricula of medical, dental, occupational therapy (OT) or speech and language therapy (SLT) programs. Studies were screened for eligibility with set inclusion criteria. Data were extracted and analyzed. Analysis revealed that UDL was not specifically mentioned in any of the studies thus there are no published studies on UDL being formally applied in healthcare education. However, the authors identified 33 publications that described teaching methods which aligned with UDL in anatomy curricula and a thematic analysis yielded four main themes relating to teaching strategies being employed. Universal design for learning was not mentioned specifically, indicating that educators may not be aware of the educational framework, although they appeared to be utilizing aspects of it in their teaching. The review revealed that there is a lack of research concerning the anatomy education of OT and SLT students. The role of UDL in enhancing motivation to learn anatomy in medical, dental, OT and SLT programs has yet to be explored.  相似文献

The low rates of child literacy in South Africa are cause for considerable concern. Research from the developed world shows that parental sharing of picture books with infants and young children is beneficial for child language and cognitive development, as well as literacy skills. We conducted a pilot study to examine whether such benefits might extend to an impoverished community in South Africa, by evaluating the impact of training mothers in book sharing with their 14–18 month old infants. Seventeen mothers received book sharing training; and 13 mothers did not, but instead received a comparison training in toy play. We assessed the mothers’ behavior during both book sharing and toy play before and after training, and we also assessed infant attention and language. Mothers receiving book sharing training engaged well with it, and they also benefited from it; thus, compared to the comparison group mothers, they became more sensitive, more facilitating, and more elaborative with their infants during book sharing, and they also became more sensitive to their infants during toy play. In addition, infants whose mothers received the book sharing training showed greater benefits than the comparison group infants in both their attention and language. Training in book sharing for families living in conditions of marked socio-economic adversity in South Africa has the potential to be of considerable benefit to child developmental progress. A large scale controlled trial is required to confirm this.  相似文献

Abstract

The objective of the present study was to monitor the immunological and hormonal responses and the occurrence of upper respiratory symptoms in adolescent basketball athletes during the different stages of a sports season. Anthropometric measures, biochemical analyses (interleukin-6, interleukin-10, tumour necrosis factor-alpha, C-reactive protein, testosterone and cortisol), neuromuscular evaluations (standing vertical jumping ability, agility and estimated VO2max) and leukocyte counts were performed at four moments: 72 h before the season (?72 h); before the season (Pre-season); after six weeks, at the end of the preparatory period (Preparatory); and after 20 weeks, at the end of the competitive period (Competitive). Also, the occurrence of upper respiratory symptoms was collected weekly during all stages of the season. There were significant increases in monocytes, cortisol, tumour necrosis factor-alpha and C-reactive protein at the Competitive moment as compared to the Pre-season. In addition, interleukin-10 decreased at the Competitive moment as compared to the Pre-season. Occurrence of upper respiratory symptoms demonstrated increases (38%) during the competitive period as compared to the preparatory. These results suggest that periods of training and competition could increase the occurrence of upper respiratory symptoms in adolescent athletes and this may be due to the unwanted effects of an inflammatory process in response to the excessive stress of training and competition.  相似文献

ABSTRACT

This study used the intensity gradient (IG) and average acceleration metrics to describe children’s activity profiles and explore associations with body mass index (BMI) z-score. Two hundred and forty-six children (n = 138 girls) aged 9.6 ± 1.4 years wore a wrist-mounted ActiGraph wGT3X-BT accelerometer for 7 days on their non-dominant wrist. Physical activity (PA) metrics captured included: the IG which describes the intensity distribution of accelerations across the 24 h monitoring period; average acceleration which provides a measure of the volume of activity; total moderate-to-vigorous PA (MVPA) and inactive time. Acceleration was averaged over 5s epochs. Finally, BMI z-score was calculated for each participant. Average acceleration was negatively associated with BMI z-score (p < 0.05) independent of age and gender but not IG. The IG was negatively associated with BMI z-score independent of potential correlates and average acceleration. Total MVPA was not associated with BMI-z score. The IG and average acceleration metrics may be used to explore the independent or cumulative effects of the volume and intensity distribution of activity upon measures of health and well-being in children to inform specific activity recommendations.  相似文献
