This paper explores the significance of contemporary celebrity businesswomen as role models for women aspiring to leadership in business. We explore the kind of gendered ideals they model and promote to women through their autobiographical narratives, and analyse how these ideals map against a contemporary postfeminist sensibility to further understand the potential of these role models to redress the under‐representation of women in management and leadership. Our findings show that celebrity businesswomen present a role model that we call the ‘female hero’, a figure characterized by 3Cs: confidence to jump over gendered barriers; control in managing these barriers; and courage to push through them. We argue that the ‘female hero’ role model is deeply embedded in the contemporary postfeminist sensibility; it offers exclusively individualized solutions to inequality by calling on women to change themselves to succeed, and therefore has limited capacity to challenge the current gendered status quo in management and leadership. The paper contributes to current literature on role models by generating a more differentiated and socially situated understanding of distant female role models in business and extending our understanding of their potential to generate sustainable and long‐term change in advancing gendered change in management and leadership. 相似文献

Sleep problems are common and impair the health and productivity of employees. Work characteristics constitute one possible cause of sleep problems, and sleeping poorly might influence wellbeing and performance at work. This study examines the reciprocal associations between sleep problems and psychosocial work characteristics. The participants were 1744 full-time employed individuals (56% women; mean age 38 years in 2007) from the Young Finns study who responded to questionnaires on work characteristics (conceptualised by the demand–control model and effort–reward imbalance model) and sleep problems (Jenkins Sleep Scale) in 2007 and 2012. Cross-lagged structural equation models are used to examine the associations. The results show that low control and low rewards at baseline predicted sleep problems. Baseline sleep problems predicted higher effort, higher effort–reward imbalance, and lower reward. Sleep problems also predicted lower odds for belonging to the low (rather than high) job strain group and active jobs group. The association between work characteristics and sleep problems appears to be reciprocal, with a stressful work environment increasing sleep problems, and sleep problems influencing future work characteristics. The results emphasise the importance of interventions aimed at both enhancing sleep quality and reducing psychosocial risks at work. 相似文献

This paper studies the effect of product market competition on the explicit compensation packages that firms offer to their CEOs, executives and workers. We use a large sample of both traded and nontraded UK firms and exploit a quasi‐natural experiment associated to an increase in competition. The sudden appreciation of the pound in 1996 implied different changes in competition for sectors with different degrees of openness. Our difference in differences estimates show that a higher level of product market competition increases the performance pay sensitivity of compensation schemes, in particular for executives.

Organizational innovation is essential to economic development. But, the way successful societies have organized new ventures
has been remarkably similar in both past and present. The commenda organizations of medieval Italy shared many characteristics
with modern startups that are financed by venture capital. Profit share contracts; limited liability and periodic reevaluations
are cases in point. Agency contracts in both types of ventures are designed to absorb the high uncertainty inherent to these
enterprises through risk sharing. Uncertainty prohibits a unique ex ante ranking order of investment projects and prompts
investors to look for hidden human capital. Equity finance is better equipped to even out unexpected losses and gains that
are inherent to uncertainty than debt finance. 相似文献

The business model has become a popular concept in business and management fields. Yet, it is suffering from a paradox between outstanding popularity and severe criticism, which appears to impede the positive development of the scholarly discourse on the business model concept. Against this background, the purpose of this study is to provide insight into the antecedents of this paradox and to understand their implications for the future development of the concept. The following contributions are made. First, the authors apply a narrative approach to recognizing and interpreting the paradox, and introduce the analysis of syntactics of scholarly discourse as a novel method of investigating management concepts. Second, as a result of elaborating on recurrent themes and tensions in scholarly discourse, the authors extend the literature on business models through theorizing on the core of the concept along the dimensions of classification, constitution and configuration. In particular, they identify the simultaneity of separation and attachment as the main antecedent of the business model paradox. Third, the authors offer implications for further advancing the development of this management concept, and highlight the need for spurring integrative research while at the same time maintaining a plurality of perspectives. 相似文献

Two studies examined relationships between leaders' and subordinates' attachment orientations, emotion regulation capabilities, and affective experience and satisfaction at work. As expected, supervisors' and subordinates' insecure attachment orientations (higher anxiety and avoidance) were associated with own positive affect and satisfaction at work. Supervisors' anxious attachment orientation was associated with subordinates' lower positive affect and satisfaction at work. Contrary to hypotheses, supervisors' higher avoidance was associated with subordinates' lower negative affect and higher job satisfaction. Supervisors' emotion regulation capabilities did not mediate relationships between supervisors' insecure attachment orientations and supervisors' own or subordinates' affect and job satisfaction as expected. However, subordinates' emotion regulation capabilities interacted with supervisors' attachment orientations to predict subordinates' emotion experience at work. The results contribute to an understanding of attachment orientations' emotion dynamics in leader–follower interaction, pointing in particular to perceptual and affect-related processes at different levels of analysis. 相似文献

Research on the risk of motor vehicle injuries and their relationship with the amount of travel has been only partially analyzed. The few individual exposure assessments are related to very specific subsets of the driving and traveling populations. This study analyzes the relationship between kilometers traveled and hospitalization due to motor vehicle injuries. Twelve thousand three hundred and sixty nine Spanish university graduates from the Seguimiento Universidad de Navarra multipurpose cohort study were evaluated. They had not been hospitalized due to motor vehicle injuries at baseline and were followed up to eight years. Biannual questionnaires allowed for self‐reporting of kilometers traveled in motor vehicles, together with incidence of hospitalization. Covariates in the Cox regression models included age and gender and baseline use of safety belt while driving, driving a vehicle with driver‐side airbag, driving a motorcycle, and drinking and driving. There were 49,766 participant‐years with an average yearly travel of 7,828 km per person‐year. Thirty‐six subjects reported a first hospitalization event during this time. The adjusted hazard ratio per additional kilometer traveled was 1.00005 (95% confidence interval 1.000013 to 1.000086). Even the smallest of reductions in the amount of kilometers traveled (from an average of 3,250 km per year to 1,000) has a statistically significant protective effect on the likelihood of sustaining hospitalization due to motor vehicle injury (aHR 0.9, 95% CI 0.78 to 0.98). In light of current policies aimed to reduce motorized traffic due to environmental concerns, it may be appropriate to consider the additional health benefit related to reductions in injuries. 相似文献

In risk assessment, no observed exposure level (NOAEL) and benchmark dose (BMD) are usually derived either from epidemiological studies in humans or from animal experiments. In many in vitro studies, concentration-effect/response curves have been analyzed using different mathematical models finalized to the identification of EC50. In the present article, we propose a model to fit dose-response curves in vitro. The BMD approach has been used to compare the cell viability (MIT assay) of different rat (C6 and PC12, glial and neuronal, respectively) and human cell lines (D384 and SK-N-MC, glial and neuronal, respectively) after 24-hour exposure to the following neurotoxic substances: manganese chloride (MnCl2), methyl-mercury (Me-Hg), and the enantiomers of styrene oxide (SO). For all rat and human cell lines, the potency of the examined compounds was: MnCl2 < S-SO < R-SO < Me-Hg. A preliminary comparison with in vivo toxicity data for these substances gave rise to consistent results. Whereas a reasonable agreement between in vitro and in vivo data has been found for Mn and styrene oxide, a wide scatter of LOAEL has been reported for Me-Hg and these appear to be either much higher or lower than the BMD for the MIT assay we observed in vitro. 相似文献
