The current study examined passive leadership as a potential antecedent of two commonly studied workplace stressors (i.e. workload and work–family conflict), and investigated its negative effect on employee burnout and physical symptoms via these stressors. We collected two waves of data from 274 focal participants, and one wave of data from their co-workers. Results showed that both self-reported and co-worker-reported passive leadership was positively related to employee burnout and physical symptoms, as well as workload and work–family conflict. Additionally, workload and work–family conflict partially mediated the effects of passive leadership on burnout and physical symptoms, respectively. Our findings support the notion that passive leadership can create a stressful workplace and have a detrimental effect on employees’ health.  相似文献

This study redresses a gap in the literature concerning the outcomes of emotion work by exploring how both integrative and masking emotion work relate to marital quality and marital conflict. Using data from a random sample of dual-earner couples in a northeastern city in an upper Midwestern state (n = 99 couples), this study explores the emotion-work performance of each partner. The findings show that men’s integrative emotion work is only significantly associated with men’s marital quality, whereas men’s masking emotion work significantly predicts their partner’s marital quality, men’s marital quality, and men’s marital conflict. Women’s integrative emotion work is significantly associated with women’s marital quality and their partner’s marital conflict, whereas women’s masking emotion work predicts women’s marital quality and marital conflict. Altogether, the findings suggest that considering both masking and integrative emotion work helps gain a fuller understanding of how emotion work shapes marital outcomes.  相似文献

How do young children negotiate conflicts with peers that result in mutually beneficial resolution and peaceful interaction after conflict? A few studies suggest that when children use conciliatory strategies in conflict, socially adaptive outcomes are more likely to be achieved. The present study explores the relative associations of types of children's conciliatory conflict resolution strategies (i.e., prosocial, compliance‐oriented, solution‐oriented, and verbal clarification/apology) with conflict outcomes to contribute to knowledge of the discrete behaviors that might have salience for conflict resolution training. Socially adaptive conflict outcomes were expected to strongly relate to children's resolution strategies of a prosocial nature as well as to teacher or peer interventions encouraging prosocial behavior or empathy. Sampled conflicts (N = 521) were collected through field observations of 107 ethnically/racially and socioeconomically diverse four‐ to seven‐year‐old children. Logistic regression analyses with bootstrap‐based inference suggested that children's prosocial behaviors in conflict were most strongly tied to mutually beneficial resolution and peaceful postconflict interaction, when controlling for relevant covariates. Other conciliatory strategies varied in their association with socially adaptive outcomes. The hypothesis regarding third‐party interventions encouraging prosociability or empathy could not be examined due to infrequent occurrence. Insights for future research on children's socially adaptive conflict negotiations are discussed.  相似文献

从国内来看,近年来和谐哲学的研究主流是围绕斗争哲学而展开的,此外,还有一部分学者从系统论和理念创新的角度研究和谐哲学,可视为和谐哲学研究的两条支流。当今和谐哲学命题自身面临着生存危机;和谐哲学的儒化思想严重;和谐哲学理论体系亟待建立等诸多问题。未来的和谐哲学研究内容应扩大眼界,汲取百家之长;和谐哲学研究界域应控制在学术领域,避免将学术争辩上升到政治斗争;和谐哲学研究范围不应仅限于国内,还应扩展到国外。  相似文献

ABSTRACT

In recent years, Sierra Leone has witnessed intense population movements. During the civil war (1991–2002), many populations fled the fighting zones of the interior to take refuge on the coast. Since the conflict ended, new populations have reached the coastal area with the hope of accessing economic opportunities in the fishing business. Mobility, along with changing sociopolitical and economic conditions, has generated conflict between immigrants and Sherbro populations, who consider themselves autochthonous and deny migrants the freedom to access political and land rights. The paper argues that present dynamics of conflicts are rooted in long-term patterns of settlement and relationships of reciprocity between groups. Relations between migrants and local populations are grounded in a sociocultural idiom that implies the institutionalization of practices of reciprocity between local inhabitants (hosts) and later settlers (strangers). The host/stranger reciprocity system is an emic model of cultural action embedded in historical and power relations between groups. It implies the progressive integration of strangers into the host society. This paper highlights how, in a situation of conflict, long-established social relationships between groups are reevaluated with reference to norms of integration and reciprocity. The paper draws on Sherbro oral traditions to show how social memories about interethnic relations are reframed with reference to values and expectations of reciprocity, in order to explain the recent conflict that opposes Sherbros to immigrants. Sherbros use oral traditions to interpret these tensions in a long-term perspective, thereby expressing their own view on settlement, conflict and integration.  相似文献

I propose a lens model for understanding how core identities (ethnic, sectarian, racial or national) are affected by past interactions and narratives increasing the chances of the outbreak of violent conflict. The model can be used to show how core identities are polarized during conflict escalation and how they might de-polarize during periods of de-escalation and conflict resolution, leading to potential transformation of core identities in post-conflict situations. Northern Ireland will be used to illustrate the Integrated Relational Identity Structure model, showing how conflicting identities have changed, or not, as a result of history, the conflict and the peace process.  相似文献

Parental depression is a well‐established risk factor for couple conflict and ineffective or hostile parenting (M. C. Lovejoy, P. A. Graczyk, E. O'Hare, & G. Neuman, 2000; L. M. Papp, M. C. Goeke‐Morey, & E. M. Cummings, 2007). Although research suggests that caregiver depression may impact parenting indirectly via increased conflict between couples (e.g., R. D. Conger et al., 2002), few studies take into account the behaviors of both caregivers in exploring these relations. The goal of the current study is to employ an actor–partner mediator model to examine the complex relations among psychological distress, negative couple interactions, and parenting. Using a sample of 162 African American couples with children, we find evidence that the psychological distress of each caregiver has an effect on couple interactions for both men and women. The effects from each caregivers' distress to parenting are mainly indirect through the interactional behaviors of the mother toward the father, consistent with the father vulnerability hypothesis (e.g., E. M. Cummings, M. Goeke‐Morey, & J. Raymond, 2004).  相似文献

The objective of meat inspection is to promote animal and public health by preventing, detecting, and controlling hazards originating from animals. With the improvements of sanitary level in pig herds, the hazards profile has shifted and the inspection procedures no longer target major foodborne pathogens (i.e., not risk based). Additionally, carcass manipulations performed when searching for macroscopic lesions can lead to cross‐contamination. We therefore developed a stochastic model to quantitatively describe cross‐contamination when consecutive carcasses are submitted to classic inspection procedures. The microbial hazard used to illustrate the model was Salmonella, the data set was obtained from Brazilian slaughterhouses, and some simplifying assumptions were made. The model predicted that due to cross‐contamination during inspection, the prevalence of contaminated carcass surfaces increased from 1.2% to 95.7%, whereas the mean contamination on contaminated surfaces decreased from 1 logCFU/cm² to ?0.87 logCFU/cm², and the standard deviations decreased from 0.65 to 0.19. These results are explained by the fact that, due to carcass manipulations with hands, knives, and hooks, including the cutting of contaminated lymph nodes, Salmonella is transferred to previously uncontaminated carcasses, but in small quantities. These small quantities can easily go undetected during sampling. Sensitivity analyses gave insight into the model performance and showed that the touching and cutting of lymph nodes during inspection can be an important source of carcass contamination. The model can serve as a tool to support discussions on the modernization of pig carcass inspection.  相似文献

Story stem measures are an increasingly popular method for assessing the attachment representations of young children, but little is known of their cross‐cultural applicability. This study aimed to characterise the attachment representations in 73 five‐ to eight‐year‐old children in urban Ghana, West Africa, using the Manchester Child Attachment Story Task (MCAST) to test its feasibility, psychometric characteristics and concurrent associations with caregiver‐ and teacher‐rated child behaviour, and to conduct a qualitative thematic analysis of methodological observations. Among the classifiable cases (92 percent), all attachment classifications were observed, yielding a higher rate of secure attachment than in European samples. Inter‐rater reliability, internal consistency, and internal structure were reasonable and largely similar to European studies, although one structural difference was the separation of ‘child assuagement of distress’ from other secure‐related items. MCAST narratives were associated with teacher‐ and caregiver‐rated hyperactivity, but internal consistency was low in most Strengths and Difficulties Questionnaire scales. Possible culturally‐sensitive explanations for our psychometric and qualitative findings are discussed. Overall, story stems are a promising tool for accessing attachment representations in non‐Western samples, although modifications are likely to improve cross‐cultural equivalence when applied to non‐Western cultures. Further investigation is needed to link MCAST outcomes to parenting and socio‐emotional development.  相似文献
