University policies prohibiting use of mobile devices by medical students during clinical placements are contradicted by regular use by physicians. Consequently, many students use their mobile devices, which can be beneficial for learning but may put patient privacy at risk. This study explores the reasons underlying students' decisions about using mobile devices in clinical settings. We used a mixed-methods sequential explanatory design involving a questionnaire and focus groups. Qualitative data from the questionnaire and focus groups was analysed through thematic analysis. We found students were aware of the risks mobile devices posed to professionalism and medical practice. Despite prohibitions, many made individual decisions to use mobile devices because the benefits outweighed the risks. These students were influenced by an organised, strategic approach to learning and a motivation to comply with the beliefs and behaviours of their medical teams and conform to physicians' directives in order to participate in their community of practice. Many students appear to be transferring everyday use of mobile devices to clinical settings. There is a need to understand and promote aspects of learning that are enhanced by mobile devices in clinical settings, while articulating clear guidelines and boundaries compatible with the professional behaviour expected of students.  相似文献

In this study, the author reports on the professional learning of three primary teachers who engaged in three cycles of collaborative action research over a three-year period from 2013 to 2016. Case study was chosen as a methodology to gain insight into the context of the teachers’ work as they interacted with others and adopted multiple tools. Data collection and analysis were on-going over a three-year period, using several sources, including classroom observations, interviews, portraits and teacher-created multimedia artefacts. Cultural-Historical Activity Theory (CHAT) and its activity system unit of analysis (subject, object, tools, norms, community and division of labour) was used by the author to describe changes in the professional learning of the three teachers, the contradictions or tensions they addressed, and how they transformed the aspects of their professional knowledge and classroom practice.  相似文献

Despite some controversy, there is an emerging body of knowledge regarding the nature, prevalence, assessment, and treatment of childhood depression. The following study was undertaken to determine how this knowledge compares with the perceptions and practices of school psychologists in two north central states. A need for school psychologists to define the concept of childhood depression is identified. Use of DSM III-R for the diagnosis of childhood depression in the schools and the inclusion of standardized measurement techniques in the assessment process are advocated. Involvement of school psychologists in the treatment process, either directly or indirectly, is also recommended.  相似文献

BackgroundOne-hour postprandial hyperglycemia is associated with increased risk of type 2 diabetes and cardiovascular disease. Physical activity (PA) has short-term beneficial effects on post-meal glucose response. This study compared the oral glucose tolerance test results of 3 groups of people with habitually different levels of PA.MethodsThirty-one adults without diabetes (age 25.9 ± 6.6 years; body mass index 23.8 ± 3.8 kg/m2; mean ± SD) were recruited and divided into 3 groups based on self-reported PA volume and intensity: low activity < 30 min/day of moderate-intensity activity (n = 11), moderately active ≥ 30 min/day of moderate-intensity PA (n = 10), and very active ≥ 60 min/day of PA at high intensity (n = 10). Participants completed an oral glucose tolerance test (50 g glucose) with capillary blood samples obtained at baseline, 15 min, 30 min, 45 min, 60 min, 90 min, and 120 min post-ingestion.ResultsThere were no significant differences between groups for age or body fat percentage or glycated hemoglobin (p > 0.05). The groups were significantly different in terms of baseline glucose level (p = 0.003) and, marginally, for gender (p = 0.053) and BMI (p = 0.050). There was a statistically significant effect of PA on the 1-h postprandial glucose results (p = 0.029), with differences between very active and low activity groups (p = 0.008) but not between the moderately active and low activity groups (p = 0.360), even when baseline glucose level and gender differences were accounted for. For incremental area under the curve there was no significant effect of activity group once gender and body fat percentage had been accounted for (p = 0.401). Those in the low activity group took 15 min longer to reach peak glucose level than those in the very active group (p = 0.012).ConclusionThe results suggest that high levels of PA have a beneficial effect on postprandial blood glucose profiles when compared to low and moderate levels of activity.  相似文献

This brief viewpoint piece depicts educational (dis)engagements apparent in researching and (re)designing higher education in and through Accessions. Accessions, a collaborative research-design project, probed at how cultures, climates and conditions of higher education may be reproducing or reshaping social inequalities and divisions. Here, questions are asked about how these might be challenged within and potentially beyond the specific locale of one university campus. This research-design project hopes to enable a critical perspective on issues of ‘participation’, ‘impact’, ‘engagement’ and ‘internationalisation’, where regulations and measures may be resisted and disrupted.  相似文献

The purpose of this study was to compare measures of body size in two samples of youth baseball players with normative data from the United States National Center for Health Statistics (NCHS) growth charts. One sample of youth baseball players participated in a local little league. The second sample of youth baseball players were members of eight of the twelve teams participating in the 1995 Dixie Youth World Series. Normative data for the United States (NCHS) were used as comparative data. Two trained anthropometrists measured standing height, sitting height, lower limb height, upper limb length, arm girth, calf girth, tricep skinfold, and abdomen skinfold on all participants. In both samples, pitchers, short stops, and first basemen were a more highly skilled group and exhibited larger body size (greater standing height, sitting height, lower limb height, upper limb length) than children who played at other positions. The standing height of local little league players was similar to the median of reference data at ages 7, 8, and 9 years. The standing height and weight of skilled players in both samples approximated the 75th percentile for standing height and weight at ages 10, 11, 12, and 13 years. The results suggest that baseball players exhibit larger body size than the normal population at young ages. Body size may be an important criterion used by coaches to select and assign young players to certain positions.  相似文献
