- Subordinate's trust in the supervisor and its impact on organizational effectivenessPublication . Afsar, Bilal; Saeed, Bilal BinThis study tested a model of trust-in-supervisor that included propensity to trust and supervisor attributes (i.e., ability, benevolence, and integrity) as antecedents, and affective organizational commitment and helping intention as criterion outcomes. A field survey using a structured questionnaire was used to gather data from 255 white-collar employees from diverse occupations and organizations. Path analysis results showed that supervisor ability, benevolence, and integrity as well as employees' propensity to trust were positively associated with trust-in-supervisor. Trust in-supervisor, in turn, predicted employees' affective organizational commitment but did not have any influence on their willingness to help co-workers. Implications of the findings and suggestions for future research are discussed.
- Initial capital structure of portuguese innovative firms : the role of nascent entrepreneurs' human capitalPublication . Couto, Eduardo; Bilau, JoséThe aim of this study is to analyse whether the human capital of the nascent entrepreneur influences the initial capital structure of Portuguese innovative firms. The research model used includes a dependent binary variable devised to check the initial capital structure, two groups of independent variables referring to the human capital and a group of control variables. The results obtained through logistic regression show that "heterogeneity of professional experience" positively influences the initial capital structure. These results contribute to the scientific knowledge by showing that generic human capital influences the initial capital structure of the innovative firm. Our study also makes a contribution to the literature on entrepreneurial finance in terms of methodology.
- Strategies employed by e-commerce firms in Portugal : an empirical investigationPublication . Torres, Pedro Marcelo; Lisboa, João Veríssimo; Yasin, Mahmoud M.A survey integrating different theoretical views of value creation was developed, then sent to Portuguese e-ommerce firms to assess the underlying dimensions and the most important characteristics of their e-Commerce strategies. The survey was sent to 188 firms in 2007 and repeated in 2010 to validate the results, obtaining a total sample of 62 e-Commerce firms. Through factorial analysis, three e-Commerce strategy dimensions were identified: one relates to differentiation via marketing based on reputation and brand identification, in which advertising and innovation in marketing techniques and methods are important; a second differentiation dimension focuses on product development and is supported by technical capabilities; and a cost leadership dimension which uses strategic networks to obtain economies of scale and scope, and exploits technological advancements to reduce transaction costs.
