How does servant leaders' unique ability to place each follower's needs above their own influence relationships between followers and impact their collective performance? In a study that integrates principles of servant leadership with the social comparison theoretical framework, we tested a group-level model to examine how servant leadership induces low perceived differentiation in leader-member relationship quality (perceived LMX differentiation) within a group, which strengthens team cohesion and in turn positively influences team task performance and service-oriented organizational citizenship behaviors (service OCB). Our sample comprised 229 employees nested in 67 work teams. Structural equation modeling results indicate that servant leadership significantly predicts low perceived LMX differentiation; perceived LMX differentiation is strongly related to team cohesion such that the lower the perceived differentiation, the stronger the team's cohesiveness. And, team cohesion is also strongly related to both the team's task performance and service OCB. Perceived LMX differentiation and team cohesion mediate the effect of servant leadership on both team task performance and service OCB.  相似文献

The goal of the current study was to examine two competing models focusing on the roles of empathy‐related traits in the relation between economic stress and prosocial behaviors. First, we examined the mediating roles of perspective taking and empathic concern in the association between economic stress and adolescents’ prosocial behaviors. Second, we examined the moderating role of perspective taking in the association between economic stress and empathic concern, as well as the links between empathic concern and prosocial behaviors. Participants consisted of 307 (46.2% girls; M age = 15.05) U.S. Latino adolescents (77.5% U.S. Mexicans) and their primary caregivers (87.9% mothers). Primary caregivers reported on family‐level economic stress, and adolescents reported on their own perspective taking, empathic concern, and their tendency to engage in six forms of prosocial behaviors. Results demonstrated support for the moderating role of perspective taking on the link between economic stress and empathic concern, which in turn, was associated with multiple forms of helping behaviors. Economic stress was also directly associated with selfless and selfish helping behaviors. The discussion focuses on the multiple roles of empathic traits in understanding the links between economic stress and prosocial outcomes in U.S. Latino youth.  相似文献

The study surveyed 506 employees in the United States to test the effect of internal communication (i.e., corporate-level symmetrical and leadership-level responsive communications) on fostering a positive emotional culture characterized by companionate love, joy, pride, and gratitude. In addition, we tested the interplay between corporate internal communication and a positive emotional culture and its influence on supportive employee behaviors, specifically, organizational citizenship behavior (OCB) and employee advocacy. Results indicated that symmetrical communication and responsive leadership communication cultivated a positive emotional culture in organizations. Such culture also fostered employee OCB and advocacy. Moreover, corporate symmetrical communication directly and positively influenced employee OCB. Finally, this study found that employee OCB positively affected employee advocacy. The theoretical and practical implications of the findings for public relations scholars and practitioners were discussed.  相似文献

ABSTRACT

Older adults account for 17% of new HIV diagnoses in the US and are more likely to be diagnosed with HIV later in the course of the disease compared to younger people. We calculated the prevalence and associated factors of having ever been tested for HIV among sexually active older adults. We analyzed data from the 2008–2016 General Social Survey Limited to respondents ≥65 years of age who reported more than one sex partner(s) in past 12 months (n = 757). HIV testing prevalence, prevalence ratios, and 95% confidence intervals were calculated by demographic variables and HIV-related risk behaviors. An estimated 16.3% of sexually active older adults have tested for HIV, and 15.9% were at increased risk for HIV infection (reported injection drug and/or crack–cocaine use, exchanging money for sex, more than three sex partners in the past year, or men who reported having sex with another man). In the adjusted model, adults aged 65–70, not married, self-identified as gay/bisexual, and at increased risk for HIV infection were more likely to have tested for HIV. An estimated 83.7% of sexually active older adults never tested for HIV. Strategies are needed to increase HIV awareness and testing among potentially high-risk older adults.  相似文献

Using mixed methods, we explored the role of coercive controlling behaviors in a high-risk sample of 126 men in violent same-sex relationships. Contrary to a prediction that separate factors of physical violence and coercive control might emerge, a simple principle components analysis supported that male same-sex relationship intimate partner violence (IPV) is essentially unidimensional. Qualitative narratives supported a single latent factor solution of violence, and that coercive controlling behaviors better detect IPV dynamics within the same violent encounters (i.e., weapon use), even when compared to profiles defined by physical violence. Narratives also highlighted gender-different tactics of coercion used, underscoring importance of context-based assessments.  相似文献

ABSTRACT

Cyber-safety behaviors are important in preventing the loss of an individual's digital assets and ensuring the safety of important daily online activities. Individuals’ cyber-safety is also critical for national cybersecurity. The issue is highly relevant for Israel, a country that relies on the digital capabilities of its workers for its major technology industries and is also often a target of cyberwarfare and cybercrime attacks. The purpose of this study is to identify the determinants of cyber-safety behavior. We investigate the role of age, gender and education in the use of safety-related digital skills and antivirus software. Using a 2014 survey of a national sample of Internet users in Israel (N?=?1850), we found that age, gender, education and quality of access are associated with the level of users’ digital security skills. In addition, these skills and the frequency of conducting financial activities online are the main determinants of antivirus behaviors. Our results expand the understanding of cyber-safety by showing that social and digital disparities are reproduced in the use of measures to prevent online threats, putting the digitally disadvantaged at greater risk of becoming victims of online threats.  相似文献

This study examines when and why employees engage in external communicative behaviors during the periods of a corporate crisis. Combining a cross-situational factor (i.e., pre-crisis relationship quality) and a situational factor (i.e., crisis-specific perceptions), this study segments internal publics to understand employees’ motivations of becoming advocates for or adversaries of their organization. The results of an online survey demonstrated that employees’ pre-crisis relationship to their organization plays a critical role in encouraging them to advocate for their company; meanwhile, their crisis-perception—whether they feel fewer constraints in solving a crisis—is more likely to make them share negative information externally. Segmented groups of employees with high levels of both relationship and activeness are most likely to engage in both positive and negative external communication behaviors. Theoretical and practical implications for public relations and internal crisis communication are suggested.  相似文献

Objectives: This study assessed the extent to which consuming alcohol prior to sexual activity influenced college students' verbal/behavior cues utilized to communicate consent (external consent) as well as their feelings associated with consent (internal consent). Methods: Data was collected via paper-and-pencil surveys administered to heterosexual college students (N = 794) in the United States. Results: After controlling for gender, relationship status, rape myth acceptance, and alcohol expectancies, findings indicated that alcohol consumption prior to sexual activity was associated with both internal and external consent. Conclusions: Current findings can help inform sexual assault prevention education programming given the high rates of sexual assault occurring on college campuses that involve alcohol consumption.  相似文献

针对产品缺货,本文基于顾客策略性行为在存在顾客无理由退货的条件下对两类缺货保障策略(即公开库存策略和缺货补偿策略)的价值进行了深入研究.本文分别建立了不提供任何缺货保障策略、公开库存保障策略和缺货补偿保障策略的理性预期均衡模型,通过对模型进行最优化分析发现产品缺货对最优无理由退货价格没有影响;顾客策略购买行为会破坏公开库存策略对销量的积极作用,但这种破坏作用可以通过提供慷慨的无理由退货服务来弥补,并且公开真实库存策略的价值优于公开虚假库存;当缺货补偿效用高于补偿成本时(称为有效的缺货补偿),缺货补偿策略的价值优于公开库存策略.最后,本文用Matlab软件对上述模型进行算例分析,验证了文中理论模型的正确性.  相似文献
