An important consideration in standard setting is recruiting a group of panelists with different experiences and backgrounds to serve on the standard-setting panel. This study uses data from 14 different Angoff standard settings from a variety of medical imaging credentialing programs to examine whether people with different professional roles and test development experiences tended to recommend higher or lower cut scores or were more or less accurate in their standard-setting judgments. Results suggested that there were not any statistically significant differences for different types of panelists in terms of the cut scores they recommended or the accuracy of their judgments. Discussion of what these results may mean for panelist selection and recruitment is provided. 相似文献

This essay argues that within competitive sport zero-sum logic and the theory of mutualism are compatible and complementary. Drawing on Robert Simon’s theory of mutualism and Scott Kretchmar’s argument for zero-sum logic, this article shows how athletes can strive for a clear-cut victory and shared benefits such as athletic excellence fully and wholeheartedly at the same time. This paper will also consider how acknowledgment of this dynamic could advance understandings for ethical theories for sport. It will then conclude by describing a subjective approach that will make the affinity of zero-sum logic and mutualism more accessible for sports people. 相似文献

The importance of increasing interest in the STEM disciplines has been noted in a number of recent national reports. While many previous studies have focused on such efforts inside of the formal classroom, comparatively few have looked closely at informal learning environments. We investigate the innovative use of technology in informal learning by reviewing research on the incorporation of augmented reality (AR) at exhibit-based informal science education (ISE) settings in the literature. We report on the common STEM-focused topics that are covered by current AR applications for ISE learning, as well as the different devices used to support these applications. Additionally, we report on the prevalence of positive learning outcomes and engagement factors commonly associated with the use AR applications in informal environments. This review aims to foster continued development and implementation of AR technology in exhibit-based ISE settings by informing the community of recent findings and promoting additional rigorous research for the future. 相似文献

We present a method to add reagent to microfluidic droplets by enveloping them as a double emulsions in reagent-filled droplets and then rupturing them with an electric field. When the double emulsions rupture, they release their contents into the enveloping droplets, ensuring mixing with reagent while limiting cross-droplet contamination. 相似文献

Almost four decades ago, Kathleen Pearson examined deceptive practices in sport using a distinction between strategic and definitional deception. However, the complexity and dynamic nature of sport is not limited to this dual-categorization of deceptive acts and there are other features of deception in sport unaccounted for in Pearson's constructs. By employing Torres’s elucidation of the structure of skills and Suits's concept of the lusory-attitude, a more thorough taxonomy of in-contest sport deception will be presented. Despite the ubiquitous presence of deception in sport, few scholars have examined this concept in the sport philosophy literature since Pearson’s contribution. This paper hopes to advance a deeper understanding of deceptive practices in competitive sport and also comment on the ethical permissibility of certain sport skills from a moral perspective. 相似文献

Abstract The aim of the present study was to identify when body mass index (BMI) is unlikely to be a valid measure of adiposity in athletic populations and to propose a simple adjustment that will allow the BMI of athletes to reflect the adiposity normally associated with non-athletic populations. Using data from three previously published studies containing 236 athletes from seven sports and 293 age-matched controls, the association between adiposity (sum of 4 skinfold thicknesses, in millimetres) and BMI was explored using correlation, linear regression, and analysis of covariance (ANCOVA). As anticipated, there were strong positive correlations (r = 0.83 for both men and women) and slope parameters between adiposity and BMI in age-matched controls from Study 1 (all P < 0.001). The standard of sport participation reduced these associations. Of the correlations and linear-regression slope parameters between adiposity and BMI in the sports from Studies 2 and 3, although still positive in most groups, less than half of the correlations and slope parameters were statistically significant. When data from the three studies were combined, the ANCOVA identified that the BMI slope parameter of controls (5.81 mm · (kg · m?2)?1) was greater than the BMI slope parameter for sports (2.62 mm · (kg · m?2)?1) and middle-distance runners (0.94 mm · (kg · m?2)?1) (P < 0.001). Based on these contrasting associations, we calculated how the BMI of athletes can be adjusted to reflect the same adiposity associated with age-matched controls. This simple adjustment allows the BMI of athletes and non-athletes to be used with greater confidence when investigating the effect of BMI as a risk factor in epidemiological research. 相似文献

Abstract Officiating bias is thought to contribute to home advantage. Recent research has shown that sports with subjective officiating tend to experience greater home advantage and that referees' decisions can be influenced by crowd noise, but little work has been done to examine whether individual referees vary in their home bias or whether biased decisions contribute to overall home advantage. We develop an ordinal regression model to determine whether various measures of home advantage are affected by the official for the match and by crowd size while controlling for team ability. We examine 5244 English Premier League (EPL) match results involving 50 referees and find that home bias differs between referees. Individual referees give significantly different levels of home advantage, measured as goal differential between the home and away teams, although the significance of this result depends on one referee with a particularly high home advantage (an outlier). Referees vary significantly and robustly in their yellow card and penalty differentials even excluding the outlier. These results confirm that referees are responsible for some of the observed home advantage in the EPL and suggest that home advantage is dependent on the subjective decisions of referees that vary between individuals. We hypothesize that individual referees respond differently to factors such as crowd noise and suggest further research looking at referees' psychological and behavioural responses to biased crowds. 相似文献

The preservation of heritage through renovation projects of sport and recreation facilities is a recent phenomenon. We are not generally prompted to think of sport and recreation venues as cultural objects to preserve or as hosts to heritage, yet, they appear to be significant sources of heritage for communities and fan nations (Mason et al., 2005, Rosentraub and Ijla, 2008). Noting facilities have the ability to preserve heritage, the aim of this paper is to review contemporary philosopher Peter Singer's (1993) perspective on moral obligation to highlight the potential to protect heritage through sport and recreation facility management practices. We argue that communities and constituents may have a moral obligation to preserve heritage through sport and recreation facilities due to the value they possess. Appropriately, preservation is defined and framed as a managerial activity to assure the survival social, political, and cultural records. 相似文献
