This study explored perceptions of partner body image preferences and symptoms of disordered eating in gay and heterosexual men. Participants were male college students (= 201; M age = 20.46), and over one third identified as gay. We compared discrepancies between participants’ current and ideal body type and participants’ current body type and the body type they believed they should have to attract a dating partner. For gay men, the discrepancy between their current body and the body they believed they should have to attract a dating partner was significantly greater than the discrepancy between their current and ideal body types. In gay and heterosexual men, the discrepancy between current body and the body they believed they should have to attract a dating partner predicted eating, shape, and weight concern. Results suggest that perceptions of partner body image preferences may contribute to eating disorder pathology in men.  相似文献

Public relations (PR) practitioners are among those cultural intermediaries who privilege symbols, products, and communication rituals in society. Through interviews (n = 26) and analysis of practitioners’ Twitter accounts, this study considers how members of this field identify their personal social networking site audiences and how these behaviors are implicated in the performance of their online identity. Findings indicate practitioners feel pressure to use personal social media in accordance with field-constrained norms and that an “occupational publicness” pressure requires them to be visible online outside of the workplace. The persistent specter of public criticism from audiences and the prioritizing of organizational interests above their own self-expression limits performances of PR practitioners’ authentic selves online.  相似文献

Despite the spread of cost‐driven outsourcing practices, academic research cautions that suppliers' cost advantage may weaken manufacturers' bargaining positions in negotiating outsourcing agreements, thereby hurting their profitability. In this study, we attempt to further understand the strategic impact of low‐cost outsourcing on manufacturers' profitability by investigating the contractual form of outsourcing agreements and the industry structure of the upstream supply market. We consider a two‐tier supply chain system, consisting of two competing manufacturers, who have the option to produce in‐house or to outsource to an upstream supplier with lower cost. To reach an outsourcing agreement, each manufacturer engages in bilateral negotiation with her supplier, who may be an exclusive supplier or a common supplier serving both manufacturers. Our analysis shows that wholesale‐price contracts always mitigate the competition between manufacturers regardless of whether they compete with price or quantity. In contrast, two‐part tariffs intensify the competition when the manufacturers compete with quantity, but soften it when they compete with price. As a result, when outsourcing with two‐part tariffs, the manufacturers may earn lower profits than they would from in‐house production, although the suppliers are more cost efficient. This suggests that managers have to be wary about the downside of using coordinating contracts such as two‐part tariffs when pursuing low‐cost outsourcing strategies. Our analysis also sheds some light on the profitability of using an exclusive supplier for outsourcing. When outsourcing with wholesale‐price contracts, the competing manufacturers are better off outsourcing to an exclusive supplier. However, when outsourcing with two‐part tariffs, the manufacturers may earn higher profits by outsourcing to a common supplier than to an exclusive one when the manufacturers' bargaining power is sufficiently strong (weak) under quantity (price) competition.  相似文献

Outstanding political leaders are frequently called upon to make high-stakes decisions. Because of the controversial and highly visible nature of these issues, they often face intense criticism. Leaders' responses to criticisms not only affect follower reactions, but also the successful resolution of the contested issue. The present study examines leader and follower reactions to different types of criticisms. A historiometric approach was used to examine biographies containing criticisms of 120 world leaders and to explore leader behaviors in response to criticisms. Specifically, leader response strategies and their success in terms of follower reactions and resolution of the criticism were examined. The results indicated that collaborative or confrontational leader response strategies proved most effective in terms of the leader's ability to continue forward with a particular agenda item and to gather support of those around him or her. Conversely, avoidant, diverting attention, and persuasive response strategies proved less effective.  相似文献

Use of Acute Toxicity to Estimate Carcinogenic Risk   总被引:1,自引:0,他引:1  
Data on the effects of human exposure to carcinogens are limited, so that estimation of the risks of carcinogens must be obtained indirectly. Current risk estimates are generally based on lifetime animal bioassays which are expensive and which take more than two years to complete. We here show how data on acute toxicity can be used to make a preliminary estimate of carcinogenic risk and give an idea of the uncertainty in that risk estimate. The estimates obtained are biased upwards, and so are useful for setting interim standards and determining whether further study is worthwhile. A general scheme which incorporates the use of such estimates is outlined, and it is shown by example how adoption of the procedures suggested could have prevented regulatory hiatus in the past.  相似文献

This paper presents a mixed-method approach to measuring the functioning of Safe Schools/Healthy Students (SS/HS) Initiative partnerships. The SS/HS national evaluation team developed a survey to collect partners’ perceptions of functioning within SS/HS partnerships. Average partnership functioning scores were used to rank each site from lowest to highest. Sites with the most favorable perceptions of partnership functioning were defined as having average scores in the top 10% (n = 10) and sites with the least favorable perceptions of partnership functioning were defined as having average scores in the bottom 10% (n = 10). Qualitative data for these 20 sites were inductively open coded for emergent themes and analyzed for patterns using grounded theory approach. Six themes emerged that distinguished sites reporting the most favorable and least favorable perceptions of partnership functioning: partner engagement, facilitators, barriers, shared decision making, partnership structure, and sustainability. Sites reporting the most favorable perceptions of partnership functioning effectively utilized collaboration processes that facilitate coalition building, such as shared decision making, effective communication, and developing a clearly defined structure. Qualitative themes from this analysis provide evidence of validity for the partnership functioning scale used and illustrate distinguishing features between sites with the most favorable and least favorable perceptions of partnership functioning.  相似文献

This current issues piece will explore how autobiographies written by people with autism can help identify sensory processing differences that might be viewed as possible attributes in an enabling society, but for which ableist perceptions are often negative. In concrete terms, these constructions may be preventing people from entering employment and making an economic contribution. The first autobiography written by someone who identified as being on the autism spectrum was by David Eastham in 1985. Since then, over 50 such books have been published. The emergence of such autobiographies challenges assumptions about what it is to be on the autism spectrum. It was often assumed people with autism were incapable of such social communication, as autobiographies assume abilities such as self-awareness, imagination and the ability and desire to communicate. These were all traits that were thought to be absent in someone diagnosed with autism. Consequently, the presence of these autobiographies destabilises and questions the dichotomy that was set up between what constitutes ‘normal’ and ‘abnormal’ behaviour.  相似文献

Decision makers face difficult choices when tasked with identifying and implementing appropriate mechanisms for protecting the elderly and other vulnerable adults from abuse. A pilot project involving fingerprint-based criminal history background checks for personal care workers in Michigan has supplied an opportunity to examine one such mechanism. In conjunction with the pilot project, we have conducted a stakeholder analysis with the aim of informing decision makers about stakeholder perceptions of standard policy criteria like effectiveness, efficiency, and equity. We employed focus groups and a Web-based survey to collect data from stakeholders. While stakeholders generally see fingerprint-based background checks for personal care workers as potentially effective and as a net benefit, they also point to a variety of contingencies. They also recognize difficulties and constraints for government involvement. This preliminary analysis provides solid foundational information for decision makers and for more extensive benefit–cost analysis.  相似文献

ABSTRACT

Simulation-based learning (SBL) is a powerful tool for social work education, preparing students to practice in integrated health care settings. In an educational environment addressing patient health using an integrated care model, there is growing emphasis on students developing clinical competencies prior to entering clinical placements or clinical practice settings. This article highlights the importance of SBL in the development of the clinical competencies of graduate social work students enrolled in a Social Work Practice in Health course. The development and implementation of an educational initiative using a family-based simulation scenario to enhance classroom learning for health social work practice is described, and recommendations for future educational initiatives using SBL are provided.  相似文献
