We extend the entrepreneurship literature to include positive psychological capital — an individual or organization's level of psychological resources consisting of hope, optimism, resilience, and confidence — as a salient signal in crowdfunding. We draw from the costless signaling literature to argue that positive psychological capital language usage enhances crowdfunding performance. We examine 1726 crowdfunding campaigns from Kickstarter, finding that entrepreneurs conveying positive psychological capital experience superior fundraising performance. Human capital moderates this relationship while social capital does not, suggesting that costly signals may, at times, enhance the influence of costless signals. Post hoc analyses suggest findings generalize across crowdfunding types, but not to IPOs.  相似文献

The paper develops a general–equilibrium model with layoff unemployment to examine the effect of different unemployment insurance policies on international capital mobility. Conditions are derived under which capital will flow to the high–benefit country. Incentives for international capital movements are unaffected by how the burden of financing unemployment benefits is distributed between workers and firms. It is shown that capital outflows might have positive welfare effects for workers. This contrasts with results from standard models of international factor movements.  相似文献

Entrepreneurs need to act under conditions of uncertainty and resource constraints to bring new, often-unrecognizable products to market and convince an unknown set of stakeholders to support their endeavours. The type of action entrepreneurs take to navigate uncertain entrepreneurial contexts is underspecified. We analysed 48 interviews with entrepreneurs to inductively identify an action-oriented construct we labelled as entrepreneurial hustle – an entrepreneur’s urgent, unorthodox actions that are intended to be useful in addressing immediate challenges and opportunities under conditions of uncertainty. In a follow-up study, we use an experimental vignette approach to assess the impact of an entrepreneur’s hustle on venture stakeholders. Findings suggest that entrepreneurial hustle positively influences stakeholder perceptions of the entrepreneur’s leadership effectiveness and a venture’s legitimacy, mediated by perceptions of the entrepreneur’s ability-based trustworthiness. We conclude that entrepreneurial hustle is a fundamental behaviour that enables entrepreneurs to enrol new venture stakeholders and lead their entrepreneurial efforts.  相似文献

Abstract

Over the past four decades considerable efforts have been taken to mitigate the growing burden of road injury. With increasing urbanisation along with global mobility that demands not only safe but equitable, efficient and clean (reduced carbon footprint) transport, the responses to dealing with the burgeoning road traffic injury in low- and middle-income countries has become increasingly complex. In this paper, we apply unique methods to identify important strategies that could be implemented to reduce road traffic injury in the Asia-Pacific region; a region comprising large middle-income countries (China and India) that are currently in the throes of rapid motorisation. Using a convolutional neural network approach, we clustered countries containing a total of 1632 cities from around the world into groups based on urban characteristics related to road and public transport infrastructure. We then analysed 20 countries (containing 689 cities) from the Asia-Pacific region and assessed the global burden of disease attributed to road traffic injury and these various urban characteristics. This study demonstrates the utility of employing image recognition methods to discover new insights that afford urban and transport planning opportunities to mitigate road traffic injury at a regional and global scale.  相似文献

This study evaluated the effectiveness of red-light cameras in Dammam, the Kingdom of Saudi Arabia. Two methods were used to assess changes in crash risk at the intersections at which the red-light camera programme had been operating. Geospatial analysis was used to visualize trends in road crash density over the geographical region of Dammam and a pre--post-camera crash analysis was undertaken. The distribution of injury crashes was greater than that of crashes which included property damage, the latter of which was concentrated around central Dammam. The five red-light cameras installed in 2012 were located outside areas of high-crash and injury density, and the total number of crashes reported in the three-month periods after installation was double that before the cameras were installed. This increase in the number of crashes also occurred at the five comparison sites (without red-light cameras), indicating a null effect. The findings from this study are contrary to previous evaluations of speed management programmes associated with red-light cameras. The study highlights the challenges in obtaining data for such research and illustrates that a reliance on overt, fixed camera's to manage speed is unlikely to deliver significant reductions in road trauma.  相似文献

Formulating Hypotheses Graphically in Social Research   总被引:1,自引:0,他引:1  
This article explores the proposition that the appropriate use of suitable forms of graphic communication can improve the formulation and presentation of hypotheses in quantitative social science research. The creative nature of scientific diagrams is discussed and the technological advances in computer graphic media are seen as part of a visual revolution which is markedly changing not only the way we see things but also the way we think and do things today. Brief historical views on the use of hypotheses and diagrammatic languages in science are given. The restricted use of graphic communication tools in social research academic documents is discussed and the importance of using well-designed data graphics in the production and transmission of scientific knowledge is highlighted. Hypotheses are conceptualised and their importance within social research is emphasised. A methodological approach for formulating hypotheses graphically is proposed based on the use of three types of language: notation, statement (ordinary language) and diagram. Some criteria are suggested for the selection of diagram type dependent on the related variables. Several examples are given covering the different models proposed.  相似文献

This article argues that the study of citizenship needs to be engaged with questions raised by consumer cultures and ecological concerns. The article begins by investigating the different ways in which we might view contemporary consumer societies from the vantage point of citizenship. I go on to examine the relationship between citizenship and environmental questions. Finally, I argue that the social transformations brought about by the development of a consumer society and questions of ecological risk mean that citizenship needs to find cosmopolitan forms of expression. Unless ethical agendas are able to develop the practice of citizenship in this direction, we are unlikely to be able to find adequate political responses to some of the key dilemmas of our age.  相似文献
