Authentic leadership (AL) and positive organizational behavior (POB) are two important emerging approaches in the organizational sciences. To date, published work on AL and POB has been primarily leader-focused and based on individual differences. In this article, after verifying this individual-level focus via content coding of AL articles, AL and POB are explicated and integrated using a meso, multi-level perspective. Essentially, viewed in terms of multiple levels of analysis, AL promotes various multi-level “primary” criteria and outcomes of POB that, in turn, enhances various multi-level “secondary” criteria and outcomes of performance. Direct effects of AL on performance at multiple levels of analysis also are plausible. Implications for future meso perspectives on leadership theory and research in general and on AL and POB in particular are discussed.  相似文献

This study tracked the leadership development of236 male cadets from matriculation through graduation ata military college. Cognitive ability, physical fitness,prior influence experiences, and self-esteem measured in Year 1 were relevant to predictingthose who assumed formal leadership positions in Year 4.Physical fitness and prior influence experiencesmeasured when cadets entered the college predicted leader effectiveness rated in their fourthyear. Stress tolerance and moral reasoning levels didnot predict leader emergence or effectiveness, thoughthe set of individual difference measures significantly predicted emergence and effectiveness. Physicalfitness levels and moral reasoning increased over timefor all cadets, though surprisingly, levels ofself-esteem and stress tolerance did not increase over time. Overall the study demonstrated thatleadership effectiveness and emergence could bepredicted from early measures of individualdifferences.  相似文献

This study explored tweets that mention highly engaged companies and compared them to tweets that mention less engaged competitors. Results showed that a highly engaged company received less negative mentions in tweets, but only if the company also practiced dialogical communication. Additionally, less engaged companies received more mentions in tweets and in one instance tweets that mentioned a less engaged company shared more links with others.  相似文献

BackgroundGestational Diabetes Mellitus (GDM) during pregnancy is a risk factor for the development of Type 2 Diabetes (T2DM) within 15 years, and prevention programmes have been problematic.QuestionThe aim of the study is to identify effective strategies and programmes to decrease the risk of T2DM in women who experience GDM, the barriers to participation, and the opportunities for midwives to assist women in prevention.MethodsEnglish language, peer reviewed and professional literature published between 1998 and 2013 were searched. A systematic review of the literature was undertaken, included studies were then appraised for quality and finally findings of the studies were thematically analysed.FindingsThis review identified that there are interventions that are effective, however most lifestyle changes are difficult to translate into everyday life. As the incidence of GDM is expected to rise, midwives’ role in promoting long-term health behaviours requires further review.ConclusionsWomen need to overcome barriers and be supported in making the behavioural changes necessary to prevent T2DM following GDM. Midwives as the primary carers for women in pregnancy and childbirth are ideally positioned to educate women and engage them in lifestyle and behaviour programmes that prevent the onset of Type 2 Diabetes.  相似文献

Abstract Issues raised by the feminist epistemic critique of social science are used to examine what is meant by local knowledge and its contribution to analyses of agricultural sustainability. Employing the concepts of partial perspective, lived experience, and the complexity of social context, this paper focuses attention on the juxtaposition of local and scientific knowledge and challenges those interpretations of local knowledge production that ignore the various people, relations, and interests constituting the rural economy. An examination of local as a contested, complex, and heterogeneous domain refines the work of Kloppenburg (1991) and his commitment to the significance of local knowledge in constructing opportunities for sustainable agriculture. Attention to the on-farm gender division of labor helps to identify gender differences as critical in constituting the family farm and to elaborate how the different experiences of women and men may offer alternative visions of what constitutes sustainable agricultural production.  相似文献

Lesbian, gay, bisexual, transgender, and queer (LGBTQ) young people have been increasingly represented in traditional (offline) media over the past two decades. However, research had not adequately focused on the content of contemporary representations, how such depictions impact LGBTQ young people, or how young people’s experiences are affected by the present context characterized by the rapidly increasing prevalence of new (online) media. Utilizing grounded theory with a sample (n?=?19) of emerging adults (age 18–22), this study investigates: (1) messages about sexual orientation and/or gender identity LGBTQ emerging adults receive from LGBTQ representations in traditional media; (2) potential differences in the experiences of LGBTQ emerging adults with traditional media compared to new media; and (3) how consumption of these media messages impact LGBTQ emerging adults. Results indicate that while traditional media (particularly television) creates a common dialogue and validates identity, it continues to represent LGBTQ people as one-dimensional and stereotypical, ignores many LGBTQ sub-groups, limits LGBTQ young people’s perceptions of their future trajectories, and offers no opportunities for critique. In contrast, emerging new media offers new, important, and valued spaces for discussion and creativity.  相似文献

The paper explored how to promote constructive intergroup relations among children and young people in a context of protracted conflict. Across two studies, the Empathy–Attitudes–Action model was examined in middle childhood and adolescence. More specifically, we tested the relations among dispositional empathy, out‐group attitudes, and prosocial behaviors for youth born after the peace agreement in Northern Ireland. In one correlational (Study 1: N = 132; 6–11 years old: M = 8.42 years, SD = 1.23) and one longitudinal design (Study 2: N = 466; 14–15 years old), bootstrapped mediation analyses revealed that empathy was associated with more positive attitudes toward the conflict‐related out‐group, which in turn, was related to higher out‐group prosocial behaviors, both self‐report and concrete actions. Given that out‐group prosocial acts in a setting of intergroup conflict may serve as the antecedents for peacebuilding among children and adolescents, this study has intervention implications.  相似文献

Urban environments contain habitats for flowering plants and their pollinating animal species. It is, however, unclear how the urban matrix influences plant-pollinator processes. We recorded plant diversity, floral abundance, flower visitor diversity and plot visits at 89 plant patches within the city of Zürich. The urban matrix surrounding each site was analyzed for the landscape metrics edge density and the extent of green area up to 200 m radius. The correlation between edge density and bee diversity and visitation frequency varied over the entire spatial range, while the correlation for syrphid diversity and visitation frequency levelled off at 80 m radius. In contrast, the correlations with green area were more consistent, with bee diversity levelling off after 100 m, while syrphid diversity and visits continued to increase. The variation in the correlation of bee visits was partly accounted for by the large contribution of honeybees. Plant diversity significantly affected bee diversity and visits, and syrphid visits. Floral abundance had a positive effect on bee visits and bee diversity. Syrphid diversity had a negative interaction with floral abundance and green area. The extent of green area increased bee diversity and visits, and syrphid visits, while edge density reduced visitation by bees. This study showed that plant diversity and floral abundance in urban environments promote pollinating flower visitors. The extent of green area and edge density are important urban mosaic attributes that affect pollinator abundance and visitation frequency at multiple scales.  相似文献

Childlessness is an increasing trend, internationally and in Australia. The few studies exploring the lived experiences of childless women have been conducted in America, Canada and the United Kingdom; predominantly during the 1980s and 1990s. The experiences of childless women in contemporary Australia remain under-researched. This hermeneutic phenomenological study sought to enhance understanding of the lived experience of being a childless woman in contemporary Australia. In-depth interviews with five childless women revealed five key themes as significant facets of the experiences of childless women: notions of ‘natural’ and ‘unnatural’; woman = mother; childlessness as a discrediting attribute; feeling undervalued; and the significance of being childless. By privileging the experiences of childless women in a pronatalist society, it is apparent that misconceptions and stereotypes about childlessness continue to pervade. This study contributes to understanding this growing population group; highlighting that while childlessness is increasingly acknowledged, it is still not completely understood.  相似文献

Rates of alcohol use for sexual minority youths are nearly twice that of their heterosexual peers, yet specific risk and protective factors associated with alcohol use among sexual minority youths remain unclear. Structural equation modeling is used to examine relations among alcohol use, peer and family support, and discrimination among 207 diverse sexual minority youths. Discrimination had no relationship to alcohol use; however, it was negatively associated with peer and family support. Peer support was associated with greater alcohol use among bisexual youths. This study adds to our understanding of the roles of discrimination, social support, and alcohol use among diverse sexual minority youths.  相似文献
