Objective
The research obtained information to plan data-related products and services.Methods
Biomedical researchers in an academic medical center were selected using purposive sampling and interviewed using open-ended questions based on a literature review. Interviews were conducted until saturation was achieved.Results
Interview responses informed library planners about researchers’ key data issues.Conclusions
This approach proved valuable for planning data management products and services and raising library visibility among clients in the research data realm. 相似文献2.

Educators must address several challenges inherent to the instruction of scientific disciplines such as physics -- expensive or insufficient laboratory equipment, equipment error, difficulty in simulating certain experimental conditions. Augmented reality (AR) can be a promising approach to address these challenges. In this paper, we discuss the design and implementation of an AR and motion-sensing learning technology that teaches magnetic fields in a junior high school physics course. The purpose of this study is to explore the effects of using natural interaction on students’ physics learning and deep understanding compared to traditional learning tools. The 38 eighth graders who participated in this study were assigned to either an experimental group or a control group. Analysis of the results shows that the AR-based motion-sensing software can improve students’ learning attitude and learning outcome. This study provides a case for the application of AR technology in secondary physics education. 相似文献

Our use of regression has evolved over the last quarter century, much of which should be applauded. This article is meant to begin the process of setting standards for using regression in JOBEM while still allowing room for the evolution to continue. Some uses of regression are commendable — such as the increased use of hierarchical regression. Other practices are inconsistent, and some practices — such as ignoring assumptions — may need to change. Precise use of regression still does not make up for poor study design or measurement. 相似文献

The aim of this study was to estimate the contribution of experience, body size and maturity status to variation in sport-specific skills of adolescent soccer players. The participants were 69 players aged 13.2-15.1 years from three clubs that competed in the highest division for their age group. Height and body mass were measured and stage of pubic hair development was assessed at clinical examination. Years of experience in football was obtained at interview. Six football skill tests were administered: ball control with the body, ball control with the head, dribbling with a pass, dribbling speed, shooting accuracy and passing accuracy. Multiple linear regression analysis was used to estimate the relative contributions of age, stage of sexual maturity, height, body mass and years of formal training in soccer to the six skill tests. Age, experience, body size and stage of puberty contributed significantly but in different combinations to the variance in four of the six skill tests: dribbling with a pass (21%; age, stage of maturity), ball control with the head (14%; stage of maturity, height, body height x body mass interaction), ball control with the body (13%; stage of maturity, years of training) and shooting accuracy (8%; stage of maturity, height; borderline significance, P = 0.06). There were no significant predictors for the tests of dribbling speed and passing accuracy. In conclusion, age, experience, body size and stage of puberty contributed relatively little to variation in performance in four of the six soccer-specific skill tests in adolescent footballers aged 13-15 years. 相似文献

Changing education philosophies and technological advancement have altered the way educational content can be delivered to students. One format growing in popularity is virtual institutions which allow students to complete their secondary education completely online. While the format has been in existence for two decades, little information has been presented regarding how the shift from a traditional brick and mortar environment to a virtual one impacts the physical activity of the students. The purpose of this study is to determine the effect of school type on physical activity participation. One hundred fifteen high school age students attending brick and mortar and virtual institutions completed a survey regarding their physical activity participation. Results indicate students who attend virtual institutions are more likely to be physically active than their brick and mortar counterparts. 相似文献

ABSTRACTThis study examined the associations between socioeconomic status (SES) and musculoskeletal (MSF) and cardiorespiratory fitness (CRF) in youth. The sample consisted of boys and girls between 3-15 years. SES was categorized utilizing family-income-to-poverty ratio (FIPR). All analyses were standardized for age and sex. For each test of physical fitness, SES was used to estimate mean fitness test percentile and 95% confidence intervals, controlling for race/ethnicity and physical activity. Odds ratios were calculated for the likelihood of having low fitness by SES category. In general, the high SES group had a better composite MSF, body composition, and CRF profiles than low and moderate SES groups. Statistically significant differences were identified for relative grip strength, plank, body mass index, and cardiovascular endurance time (all p < 0.05). Additionally, the odds of low/poor MSF fitness were 1.7 and 1.6 times higher in the low and moderate SES groups (respectively) compared to the children from high SES families. The moderate SES group had an odds of poor CRF 1.6 times higher than the high SES group as well. Children and adolescents from high SES families tend to have higher mean fitness and were less likely to have low/poor fitness. 相似文献

A survey (n=280) was conducted to examine the motivational nature of enduring involvement in terms of its relationship to information source usefulness and knowledge. The results of the study indicate that enduring, or personal, involvement is associated with perceptions of greater information source usefulness and high topic knowledge. High involvement also is linked to the use of a smaller group—or repertoire—of information sources that are topic dependent. These findings suggest that highly involved audiences are active information seekers and help to clarify conflicting findings from the media reliance literature concerning the impact of reliance on knowledge. 相似文献
