A gender perspective on entrepreneurial leadership:female leaders in Kazakhstan

The paper proposes a conceptual model to understand female entrepreneurial leadership through an exploration of the perceptions and experiences of women entrepreneurs within their leadership roles. The paper addresses an existing knowledge gap on entrepreneurial leadership by bringing together three key constructs of gender, leadership and entrepreneurship. We apply Stewart's model of role demands-constraints-choices (DCC) to women entrepreneurs in Kazakhstan in order to understand their perceptions of the demands, constraints and choices they experience within their leadership roles. The results of in-depth interviews with women entrepreneurs present deeper conceptualization of their leadership enactment as a co-developing, co-constructed relational activity between leaders and others in their wider business environments and context

Dielectric response of pentagonal defects in multilayer graphene nano-cones

The dielectric response of pentagonal defects in multilayer graphene nano-cones has been studied by electron energy loss spectroscopy and ab initio simulations. At the cone apex, a strong modification of the dielectric response is observed below the energy of the π plasmon resonance. This is attributed to π → π* interband transitions induced by topology-specific resonant π bonding states as well as π*–σ* hybridization. It is concluded that pentagonal defects strongly affect the local electronic structure in such a way that multi-walled graphene nano-cones should show great promise as field emitters

Determinants of Collaborative Leadership: Civic Engagement, Gender or Organizational Norms?

This analysis attempts to unravel competing explanations of collaborative leadership styles of state legislative committee chairs. Specifically, the paper considers the influence of community or volunteer experience, gender, and institutional variables. The data show that women chairs are more likely than their male peers to cite as valuable the leadership skills and experiences that they gain through community and volunteer experience. Compared to their male colleagues, women committee chairs on average also report a greater reliance on collaborative strategies in the management of their committees. Prior community or volunteer experience has little or no direct effect on collaborative styles. In contrast, institutional factors have a much stronger and countervailing influence. Legislative professionalization produces a strong negative effect on collaborative style. Results suggest that conformity to institutional norms may be a more compelling influence than prior community experience. The analysis also points to the gendered nature of organizational leadership with men's and women's styles showing different associations to style depending on the number and power of women in a legislature.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline
