In reviewing peer-leader feedback within Multi-Source Feedback programs, the group aggregate agreement (GAA) method is contrasted with self-other agreement (SOA). Past research (Markham, Smith, et al., 2014) has demonstrated convergence problems with GAA for groups of peer raters. To evaluate dyadic convergence, we used the Benchmarks data to investigate two derailment factors (Building & Mending Relationships and Interpersonal Problems) for 4607 peers describing 1505 focal respondents. For high-agreement dyads, the rtotal = ? 0.66** with 88% of the combined variance and covariance based on dyadic averages converging as whole units. Only 50% of all dyads demonstrated this type of high convergence. For low agreement dyads, the matching correlation (rtotal = ? 0.56**) was almost exclusively a function of within-dyad divergence with only 4% stemming from between-dyad sources. Research implications for evaluating SOA under these agreement conditions are highlighted. Practitioner applications for using an entity-based visualization of dyads also are prototyped and discussed. 相似文献

Young, rural Black men are disproportionately affected by sexually transmitted infections (STIs), a consequence, in part, of multiple sexual partnerships. We conducted a prospective study that examined the influence of masculinity ideology on changes in numbers of sexual partners in this population. We focused on a set of high-risk attitudes termed reputational masculinity. Community disadvantage during young adulthood was examined as a risk factor for reputational masculinity ideology, and vocational commitment was examined as a potential protective factor. The sample included 505 African American men ages 19 to 22 from high-poverty rural communities. Men reported their numbers of sexual partners during the past three months, masculinity ideology, community disadvantage, and vocational commitment. Follow-up data were collected 18 months after baseline assessment. Negative binomial modeling was used to test study hypotheses. Results indicated that community disadvantage was associated with increases in reputational masculinity during early adulthood, which in turn were linked to increases in numbers of sexual partners. Vocational commitment interacted with reputational masculinity to forecast numbers of sexual partners, attenuating the influence of reputational masculinity. Reputational masculinity and promotion of engagement with the workplace may be important targets for interventions designed to reduce sexual risk behavior. 相似文献

In order to provide the highest quality services when court-ordered to do child custody evaluations, it is important for mental health professionals, particularly psychologists who do psychological testing, to be clear about the ethical requirements associated with the child custody evaluation process. They should be impartial, thorough, and competent focusing on the best interest of the child. Mental health professionals have been accused of unethical and illegal behavior when doing such evaluations, in part, due to the anger associated with the outcome and/or the process. The ethical issues most associated with licensing board and ethics committee complaints and civil lawsuits focus on bias, informed consent, lack of symmetry, timeliness, finances, confidentiality, negligence, chemical dependency, multiple relationships, and failure to report/omissions. 相似文献

The purpose of this paper is to present a quantitative posture analysis of microsurgery tasks performed with different visualization methods. Microsurgery is traditionally performed using a binocular microscope; however surgeons are constrained by the optical eyepieces and are forced to assume joint angles that deviate away from neutral postures. This may be especially problematic for the neck and can increase surgeon discomfort and fatigue. Alternative visualization methods may improve surgeon posture by eliminating the constraints imposed by the microscope. This study examines both 2D and 3D heads-up displays as possible alternatives. Six subjects performed microsurgical tasks with each visualization methods for four hours. Quantitative posture analysis was done using Maxtraq software that tracks reflective markers on the subjects. The initial analysis of neck, upper arm, and elbow angles found significant differences between each display. A biomechanical analysis found that the differences in angles can result in loads on the neck joint that are twice as high in the microscope than the headsup displays. Although the alternative displays can result in better postures, improvements the display technology is needed to improve microsurgical task performance. 相似文献

The measurement of walkway slip resistance is required to assess the risk of slipping. Unlike other countries, the U.S. has not decided upon a single approach to the measurement of slip resistance. Several types of tribometers are available to measure slip resistance however, the measured value of the slip resistance of a given surface has been found to be tribometer specific. The introduction of ASTM International Standard F2508 Standard Practice for Validation and Calibration of Walkway Tribometers Using Reference Surfaces, has produced a method which allows validation of each type of tribometer and the values generated during testing. 相似文献

Many scholars argue that the persistence of son preference in China is driven by greater anticipated old‐age support from sons than from daughters and the absence of formal financial mechanisms for families to save for retirement. The introduction of a voluntary old‐age pension program in rural China in the 1990s presents the opportunity to examine (1) whether parents with sons are less likely to participate in pension plans and (2) whether providing access to pension plans affects parental sex‐selection decisions. Consistent with the first hypothesis, we find that parents with sons are less likely to participate in the pension program and have less financial savings for retirement. Consistent with the second hypothesis, we find that an increase in county‐level pension program availability is associated with a slower increase in the sex ratio at birth. 相似文献

This paper uses a unique survey designed by the authors to compare migrant children who enter New Zealand through a random ballot with children in the home country of Tonga whose families were unsuccessful participants in the same ballots. We find that migration increases height and reduces stunting of infants and toddlers, but also increases BMI and obesity among 3- to 5-yr-olds. These impacts are quite large even though the average migrant household has been in New Zealand for less than 1 yr. Additional results suggest that these impacts occur because of dietary change rather than direct income effects. 相似文献

Can we construct transnational or international public service advertising to counterbalance the proliferation of transnational commercial advertising? As an important first step in exploring the possibility of such an application of shared media public diplomacy among nations, this paper describes a complete survey of commercial and public service advertisements collected from the public spaces of subway systems in American and Chinese cities in 2010 – New York, Washington, DC, Shanghai and Beijing – to reveal the range of themes of commercial and public service ads in these spaces. The study reveals first that analogous commercial and public service ads are ubiquitous in the public spaces of both Chinese and American cities. Second, many of the themes that might appear in international or transnational public service ads are already being portrayed in ads created by local or national governments or NGOs, although these themes are portrayed in ads created by different sets of actors in China and in the US: government actors and a few international NGOs in Chinese cities, and governments, corporations and non-profit organizations in the case of American cities. Finally, the survey reveals that in all four cities there are many commercial advertisements that appeal to the identity of a transnational consumer, but that there are almost no public service ads that appeal to the identity of a transnational citizen: merely local or national ones who can solve such public problems as global warming, education, and health issues. 相似文献
