This article deals with heterogeneity and spatial dependence in economic growth analysis by developing a two‐stage strategy that identifies clubs by a mapping analysis and estimates a club convergence model with spatial dependence. Since estimation of this class of convergence models in the presence of regional heterogeneity poses both identification and collinearity problems, we develop an entropy‐based estimation procedure that simultaneously takes account of ill‐posed and ill‐conditioned inference problems. The two‐step strategy is applied to assess the existence of club convergence and to estimate a two‐club spatial convergence model across Italian regions over the period 1970 to 2000.  相似文献

This paper aims to investigate how the shift from voluntary to mandatory nonfinancial information started by the European Union (EU) Directive 95/2014 may influence corporate practices. In particular, this research presents a paradigmatic case study to highlight relevant changes in reporting strategy and corporate governance adopted by an Italian listed company that never disclosed sustainability information before the transposition of the EU Directive into the Legislative Decree 254/2016. In this scenario, new obligations on nonfinancial reporting were not perceived as mere additional administrative duties and the nonfinancial statement became an opportunity to communicate company's paths towards sustainability, guaranteeing transparency and greater stakeholders' engagement. Our findings go beyond prior studies pointing out how organisations adopt strategic and tactical responses to the pressure stemming from the external environment. Additionally, it highlights the pivotal function played by the internal audit in setting up the direction of change. This research has theoretical and practical contributions for academic communities, policymakers and practitioners.  相似文献

There is a great deal of interest in Europe and the USA on the commercialization of university science, particularly the creation of spinout companies from the science base. Despite considerable research on academic entrepreneurship, female entrepreneurship in general, and the causes of under-representation of female scientists in academic institutions, there has been little research on the influence of gender on academic entrepreneurship.

The study researches female founders of UK university spinout companies using information from the Internet on company founders of spinout companies from 20 leading universities. The proportion of female founders at 12% is very low. The paper explores reasons for this low representation through follow-up postal interviews of the 21 female founders identified, and a male control sample. Under-representation of female academic staff in science research is the dominant but not the only factor to explain low entrepreneurial rates amongst female scientists.

Owing to the low number of women in senior research positions in many leading science departments, few women had the chances to lead a spinout. This is a critical factor as much impetus for commercialization was initially inspired by external interest rather than internal evaluation of a commercial opportunity. External interest tended to target senior academics, which proportionally are mostly male. A majority of the women surveyed tended to be part of entrepreneurial teams involving senior male colleagues.

As a whole both male and female science entrepreneurs displayed similar motivations to entrepreneurship, but collectively as scientists differed appreciably from non academic entrepreneurs. Women science entrepreneurs also faced some additional problems in areas such as the conflict between work and home life and networks.  相似文献

This study investigates the influence of vision and touch inputs and gender on the creativity of consumer-derived product concepts. Manipulating vision and touch richness affects how much information is apprehended from product components. Tests include solid three-dimensional components (rich inputs) and line-diagram two-dimensional components (impoverished inputs). In a controlled laboratory setting, consumers imagined products, and the product concepts' creativity was assessed on functionality and novelty. Results show that higher vision levels and touch inputs enhance the product concept's functionality, while lower levels of vision and touch inputs enhance novelty. Gender modestly affects both functionality and novelty, with women generally more creative in designing products than men.  相似文献

This study presents an updated diagnosis of the SV ecosystem itself and offers an insight into the entrepreneurial mobility trends prospects and expectations of the growing number of start-ups launched by immigrant entrepreneurs arriving in SV. The purpose is to determine and rank the attributes most valued by investors when assessing projects and start-ups founded by immigrant entrepreneurs. The model of analysis composed by three hypotheses leads to a series of findings about the profile and expectations of the immigrant entrepreneurs, and reveals remarkable hints and key targets to be met by immigrant entrepreneurs in SV in order to successfully close investment rounds in a hypercompetitive environment. The study discloses the low impact of the founder’s profile as a driver of external investment. A key conclusion states that Venture Capitalists and Business Angels in the top-ranked entrepreneurial ecosystem are primarily led by factors linked to the competitive environment and the product development process, along with the traditional performance indicators: revenue and profitability.

Civil aviation has a longstanding tradition of investigating accidents and reporting incidents, which contributes to making aviation one of the safest forms of transport.To make flying safer, independent investigation into accidents is essential as it the surest way of identifying the causes of an accident and answering the fundamental questions “What really happened?” and “What can be done to prevent similar incidents in the future?”.The obligation to investigate accidents is enshrined in the Chicago Convention of 1944. Recognizing the importance of accident investigation, the European Union adopted Council Directive 94/56/EC establishing the fundamental principles governing the investigation of civil aviation accidents and incidents and later on Directive 2003/42/EC on occurrence reporting. They both significantly contributed to harmonization of accident prevention.But with air traffic steadily increasing, accidents do happen despite the best efforts of regulators and industry. The organization of the air transport sector is much more complex now than it was a decade ago. Today there is significant divergence in the investigating capacity of the EU Member States compared to 1994. Furthermore nowadays investigating air accidents take new kinds of expertise and more resources than a decade ago. At the same time there is a new legal and institutional environment in Europe derived from the adoption of European aviation safety rules. Also the organizational set-up has changed substantially with the establishment of the European Aviation Safety Agency (EASA), which is now responsible for certifying aircraft in the EU. The EU rules on investigating air accidents need to be updated to reflect the current realities of Europe's aviation market and the complexity of the global aviation industry.Accordingly, over the last few years the European Commission has been working on a Regulation on the investigation and prevention of accidents and incidents in civil aviation, with the intention of updating and replacing the existing Directive. With this new regulation the Commission aims to promote more efficient and independent inquiries into the causes of air accidents and also expects to strengthen the rights of the victims of air accidents.Today the end is in sight, once that the Commission and European Parliament have reached an agreement about the content and text of this new regulation. Reasons behind this new regulation are presented in this paper together with a detailed explanation of its main contents, an assessment of their impact and their expected benefits.  相似文献

This paper deals with the generation of Business Ideas (BI) by academics. It investigates organizational factors affecting the process through which new ventures are established by academics and are likely to affect their performance. The BI Market Attractiveness and the BI Articulation are addressed as two characteristics of academic spin-off companies which are likely to lead to their success. Two research hypotheses are formulated: (a) that the BI Market Attractiveness at the time of establishment of the new venture is positively influenced by the market orientation of the academic founders, and by their frequency of interaction with external agents; (b) that the BI Articulation at the time of establishment of the new venture is positively affected by the articulation of roles, and by the degree of prior joint experience of the academic founders. We test our hypotheses on a sample of 42 Italian academic start-ups. Implications for both universities and academic entrepreneurs are discussed.  相似文献

The performance of small businesses, that is the ability of small firms to contribute to job and wealth creation through business start-up, survival and growth, has been an important area of policy and academic debate in the 1980s. Surprisingly little has been written about gender and small business performance. Our literature search revealed only a small number of studies of any substance on this subject, though over forty made some mention of it, Most studies shied away from direct examination of quantitative performance measures (such as jobs created, sales turnover, annual growth), tending to concentrate on qualitative measures of success or failure. The paper examines small business performance and gender using data obtained from a survey of 600 (300 women, 300 men) Scottish and English small business ownermanagers, part of a three year study on the impact of gender on small business management. Analyses suggest that the relationship between gender and small business performance is complex, but that gender still appears to be a significant determinant even after other key factors are controlled for.  相似文献
