BSW and MSW students (N = 183) read one of three vignettes and were asked to respond to 21 items investigating their perceptions about depression, anxiety, and resilience of the vignette's character. While the incidents in each vignette were identical, the main character was (a) a 75-year-old Mr. Jones, (b) a 75-year-old Ms. Jones, or (c) “Imagine you are 75 years old.” The character of each vignette had lost a spouse, was a victim of a mugging, and was exhibiting symptoms of depression and anxiety. The 21 items were analyzed by vignette type using a General Linear Model (GLM) and controlling for student type (BSW, MSW) and ethnocultural identity (member of the dominant or minority group). The GLM was significant (F = 3.020, df = 42, p = .000). There were significant differences among the vignette types in 11 of the 21 items. In general, respondents were more likely to perceive that they would be more resilient and less vulnerable at 75 than other 75-year-old men and women. 相似文献

Improving healthcare services in the developing world remains a major goal for many organizations and despite enormous training and program investments from international organizations, service improvements have been modest. This study looks at how to improve results by examining the relationship between the conditions in a healthcare providers' work environment and his or her performance. Drawing upon a human performance model that assumes that performance expectations, timely feedback, adequate environment, incentives, and skills and knowledge are required for a worker to perform well, this study explores how these conditions might affect healthcare provider performance in four countries. The study successfully shows that although multiple conditions were deficient or missing in every country, significant association is found between the performance of workers and conditions in the workers environment. Further, when viewed across all countries, non‐monetary incentives is the most powerful “predictor‘ of performance when compared with other factors. Of particular interest to Performance Improvement practitioners, knowledge and skills surfaced as important in only three of eight possible cases (with multiple cases in each country)—the least influential factor overall. 相似文献

We explored the effectiveness of distance learning and multimedia technologies in facilitating an expanded learning community
among two teachers and their students in geographically separated schools. The teachers collaboratively developed curricular
activities and identity-forming multicultural activities for their K-12 students to conduct over the distance. Predominantly
Hispanic students in a school on the Texas border with Mexico communicated regularly over a school year with diverse students
in a partner school hundreds of miles to the north. They participated in collaborative activities and shared multimedia files
via interactive videoconference. Using qualitative research methods, we discovered that the participating teachers developed
empowering multicultural relationships while their students developed multicultural understanding and positive self-concept.
Examples of empowerment and positive self-concept included raised levels of academic aspirations and heightened poise during
public speaking.

Magnetic-inertial measurement units (MIMUs) are becoming more prevalent in sports biomechanics and may be a viable tool to evaluate kinematic parameters. This study examined the accuracy of a MIMU to estimate orientation angles under static conditions and dynamically from a squash racket during a forehand drive shot. A MIMU was mounted onto a goniometer and moved through 0–90°, with static data collected at 10° increments during 10 repetitions of all three axes. Typical error analyses showed the MIMU to be very reliable (TE ≤ 0.03°). MIMU accuracy was determined via intraclass correlation coefficients (ICC) (r > 0.999, p < 0.001). An ordinary least products regression showed no proportional bias and minimal fixed bias for all axes. Dynamic accuracy was assessed by comparing MIMU and optical motion capture data of squash racket swing kinematics. A MIMU was fixed onto a racket and 10 participants each hit 10 forehand shots. Mean orientation angle error at ball impact was <0.50° and ICC showed very high correlations (r ≥ 0.988, p < 0.001) for all orientations. Swing phase root mean squared errors were ≤2.20°. These results indicate that a MIMU could be used to accurately and reliably estimate selected racket swing kinematics. 相似文献

There is inconclusive evidence concerning the effects of routine participation in ultra-endurance events on cardiovascular disease (CVD) risk. Arterial compliance is a reliable, non-invasive, and effective tool for evaluating CVD risk. The purpose of this research was to examine if race length influences acute changes in arterial compliance following an ultra-marathon event. A total of 46 ultra-marathon runners were recruited including 21 participants (39.8?±?8.3?years, 6 females) in the 80-km event and 25 participants (43.7?±?9.8?years, 3 female) in the 195-km event. Arterial compliance was measured via radial applanation tonometry (CR-2000, HDI) for diastolic pulse contour analysis before and following the race. Significant between-group differences were found for changes in large arterial compliance with a decrease (increase in stiffness) following the 195-km event and an increase following the 80-kilometre event (p?<?.05). Longer race lengths are associated with greater reductions in large arterial compliance following recreational ultra-marathon running. Assessment of arterial compliance might be a useful prognostic tool to assess the long-term risk of CVD among ultra-marathon runners. 相似文献

Key points
- Testing for accessibility after extensive changes to a website and addressing them as technical debt is unsustainable in the long term.
- To stay modern and efficient, providers of digital content to academic institutions should build accessibility into development.
- For JSTOR, working with participating institutions to understand their concerns was essential to reaching WCAG 2.0 AA conformance.
- With Artstor recently joining ITHAKA, we face the challenge of making a visual archive accessible.
