Integration of medical imaging into preclinical anatomy courses is already underway in many medical schools. However, interpretation of two-dimensional grayscale images is difficult and conventional volume rendering techniques provide only images of limited quality. In this regard, a more photorealistic visualization provided by Cinematic Rendering (CR) may be more suitable for anatomical education. A randomized, two-period crossover study was conducted from July to December 2018, at the University Hospital of Erlangen, Germany to compare CR and conventional computed tomography (CT) imaging for speed and comprehension of anatomy. Sixteen students were randomized into two assessment sequences. During each assessment period, participants had to answer 15 anatomy-related questions that were divided into three categories: parenchymal, musculoskeletal, and vascular anatomy. After a washout period of 14 days, assessments were crossed over to the respective second reconstruction technique. The mean interperiod differences for the time to answer differed significantly between the CR–CT sequence (−204.21 ± 156.0 seconds) and the CT–CR sequence (243.33 ± 113.83 seconds; P < 0.001). Overall time reduction by CR was 65.56%. Cinematic Rendering visualization of musculoskeletal and vascular anatomy was higher rated compared to CT visualization (P < 0.001 and P = 0.003), whereas CT visualization of parenchymal anatomy received a higher scoring than CR visualization (P < 0.001). No carryover effects were observed. A questionnaire revealed that students consider CR to be beneficial for medical education. These results suggest that CR has a potential to enhance knowledge acquisition and transfer from medical imaging data in medical education. 相似文献

The aim of the present study was to investigate teachers’ sickness presenteeism (SP). We examined the prevalence of SP in a sample of teachers as well as work-related and health-related influencing factors of teachers’ SP. We used a cross-sectional study design. Teachers working at different types of schools in Rhineland-Palatinate (Germany) participated in an online survey. We used Pearson’s Chi-squared test (in case of categorical variables) or Mann–Whitney-U-test (in case of continuous variables) to test for differences between SP and sociodemographic/work-related/health-related factors. Factors influencing SP were identified using multivariable logistic regression analyses. Nine hundred and twenty-four teachers working at 42 different schools completed the questionnaire (response proportion: 50.1%). The prevalence of SP in our study was 57.1%. The multivariable logistic regression analyses showed less support by supervisors (aOR: 1.77; 95-CI: 1.21–2.60), inappropriate administration efforts (aOR: 1.56; 95-CI: 1.16–2.11), and inappropriate recognition of performance (aOR: 1.44; 95-CI: 1.04–198) as well as exhaustion/fatigue (aOR: 2.29; 95-CI: 1.71–3.08) as main predictors of teachers’ SP. SP is widespread among teachers. As SP is associated with impairment of psychological and physical health in the long run, it is important to implement measures to reduce SP. A climate of support and cooperation as well as assistance for ill teachers to deal with work missed due to absence might be useful strategies. 相似文献

The purpose of the experiments was to determine the automatic use of large or small word reading units in young readers in
the absence of word decoding strategies. Picture-word Stroop interference was examined from four types of conflicting labels:
(a) words containing both highly predictable grapheme–phoneme correspondence (GPC) units and highly consistent rime units
(henceforth, Hi-GPC + Hi-Rime); (b) words with highly predictable GPC units and less consistent rime units (Hi-GPC + Lo-Rime);
(c) words with low predictability GPC units and highly consistent rime units (Low GPC + High Rime); (d) nonwords that contained
both highly predictable GPC and highly consistent rime units. Naming time for pictures containing these labels was compared
against that for pictures with random letter strings or no labels. In Experiment 1, Stroop interference was examined in first,
second, and third grade children to determine whether there was developmental change in the presence of rime or GPC interference.
In Experiment 2, Stroop interference was examined as a function of relative reading skill in first grade children. In Experiment
3, Stroop interference in adults was compared to the use of rime or GPC pronunciation strategies for nonword reading. In all
experiments, Stroop interference in picture naming was longer for pictures with highly predictable GPC unit labels than less
predictable GPC unit labels. However, in Experiment 3, even though adults showed interference from predictable GPC units in
the Stroop task, they always preferred rime pronunciation for ambiguous nonwords in the nonword reading task. It is argued
that the current experiments provide evidence for a flexible units model.
The results of this study were presented at the Cognitive Development Society meeting, November 2001, Virginia Beach, VA,

Given the significant negative impacts of peer victimization on youth development, studies have sought to understand what buffers against these consequences. To that end, the present study examined whether teacher attachment and perceptions of school safety moderated the associations between different forms of victimization and school absences over the course of an academic year among a sample of 272 high school students. Findings indicated that teacher attachment moderated the associations between relational and cyber victimization and absences, while perceived school safety moderated associations between relational victimization and absences. However, findings pertaining to cyber victimization were not as anticipated. Implications for prevention and intervention efforts in high schools are discussed. 相似文献

This paper explores recent trends in the size of scientific teams and in institutional collaborations. The data derive from 2.4 million scientific papers written in 110 top U.S. research universities over the period 1981-1999. The top 110 account for a large share of published basic research conducted in the U.S. during this time.We measure team size by the number of authors on a scientific paper. Using this measure we find that team size increases by 50% over the 19-year period. We supplement team size with measures of domestic and foreign institutional collaborations, which capture the geographic dispersion of team workers. The time series evidence suggests that the trend towards more geographically dispersed scientific teams accelerates beginning with papers published at the start of the 1990s. This acceleration suggests a sharp decline in the cost of collaboration. Our hypothesis is that the decline is due to the deployment of the National Science Foundation's NSFNET and its connection to networks in Europe and Japan after 1987.Using a panel of top university departments we also find that private universities and departments whose scientists have earned prestigious awards participate in larger teams, as do departments that have larger amounts of federal funding. Placement of former graduate students is a key determinant of institutional collaborations, especially collaborations with firms and with foreign scientific institutions. Finally, the evidence suggests that scientific output and influence increase with team size and that influence rises along with institutional collaborations. Since increasing team size implies an increase in the division of labor, these results suggest that scientific productivity increases with the scientific division of labor. 相似文献

ABSTRACTA case study demonstrating how an online narrative featuring the adventures of a cuddly toy penguin, Pablo Penguin (@uoppenguin on Twitter) has been introduced at the University of Portsmouth Library to build trust and engagement between university students and library services and facilities. Evidence for the benefits of anthropomorphic brand mascots and best practice for their design and use to enhance the library brand, emotionally engage, build trust, lower barriers to service engagement, and mentor students from the perspective of a perpetual student are drawn from the marketing and psychological literature then illustrated in the case study. 相似文献

As inclusion of young children with disabilities into preschool programs has become more prevalent, there have been concomitant changes in the roles assumed by the professionals and paraprofessionals in these programs. In this paper we examine the ways in which inclusive models influence the roles assumed by the program staff and the factors that affect the ability of staff members to assume these roles. Data, which included interviews, participant observation and document analysis, were collected as part of a multi-site national study of inclusive education programs and practices. From these data, themes emerged regarding the changing roles and relationships of staff members in inclusive early childhood programs. These themes are discussed as both facilitators of and barriers to successful inclusive programs. 相似文献
