In order to identify the effect of academic entrepreneurship on science, this work compares the publication performance of entrepreneurial scientists with that of conventional scientists. Using Stokes's ‘quadrant model’, this paper examines how the entrepreneurial orientation affects scientific performance. The results on advanced materials research in Japan found that (i) entrepreneurial scientists publish more papers than conventional scientists do; (ii) the papers of conventional scientists demonstrate better citation performance than those of entrepreneurial scientists do, on average; (iii) coming to the top-cited papers, entrepreneurial scientists show higher propensity for publishing high-impact papers than conventional scientists do; and (iv) the portfolio interdisciplinarity of papers authored by entrepreneurial scientists is higher than that of conventional scientists. Although the influence of academic entrepreneurship on scientific performance is still unclear, our findings suggest that entrepreneurial scientists could make a relatively large contribution to furthering the scientific frontier by relying on innovation rather than convention.  相似文献

Abstract

Retailers wish to expand their standard private label (PL) adopting a multi-tiered portfolio. We study the effects produced by the introduction of two new PLs quality-tiers (economy and premium) on the market share of various national brands (NB; premium-quality and second-tier) and the standard PL. This study proposes a model that accommodates three effects (similarity, attraction, and compromise) for understanding how the introduction of economy and premium PL may affect market incumbents. This study also analyzes the effects of introducing new PL quality-tiers for customer segments. Our results indicate that when economy and premium PL are introduced in the market, the choice probability of standard PL decreases, especially for high purchase quantity customers and PL loyal customers. In addition, introduction of a premium PL decreases the choice probability of second-tier NB and premium-quality NB, especially for PL loyal customers and high purchase quantity customers.  相似文献

We present a game-theoretic model for the line planning problem in public transportation, in which each line acts as player. Each player aims to minimize its own delay, which is dependent on the traffic load along its edges. We show that there exists a line plan at equilibrium, which minimizes the probability of delays of the transportation system. This result is achieved by showing that a potential function exists. Numerical results using close-to-real world data in the LinTim framework clearly show that our method indeed produces delay-resistant line concepts.  相似文献

Performance measurement of police services is complicated by ambiguous and complex goaland objectives-setting, and by the difficulties of measuring outputs. This article looks at the organizational and management changes being made in Portuguese police forces. The authors fill a gap in the literature on performance measurement in Portugal by taking a national approach to the study of how law enforcement agencies are introducing new management accounting changes. The article therefore widens the debate on performance measurement and performance improvements in law enforcement.  相似文献

Urban centres and their surroundings often act as highly dynamic economic areas. Due to continuing urban migration, population growth as well as their heightened potential for employment, they have significant impact on Germany’s overall economic performance. Cities benefit from their neighbouring regions via a division of labour based on functional and spatial comparative advantages. Jobs in the service sector are concentrated in the city, while surrounding regions show a relatively high specialisation in the industrial sector. The economic development of metropolitan regions can be fostered particularly by improving supra-regional metropolitan functions related to education and to research and development. Moreover, the improvement of the intra-regional infrastructure also contributes to the economic strength of the whole metropolitan area.  相似文献

This study addresses what factors influence and moderate Japanese physicians' mobile health monitoring (MHM) adoption for diabetic patients. In light of the multilevel sequential check theory, the study tests whether novelty seeking, self-efficacy, and compatibility moderate the effects of overall quality, net benefits, and perceived value of MHM on physicians' usage intention. Self-efficacy serves as an evaluation of resources for coping with an event, while compatibility involves the judgment of an event's congruence with a motive or goal. The study results support four out of nine moderation hypotheses. Our findings clearly indicate that the impact of overall quality and net benefits on physicians' intention to use MHM would be significantly strengthened by self-efficacy and compatibility, but not by novelty seeking.  相似文献

This paper explores entrepreneurship in the context of complex social problems (often referred to as ‘social’ entrepreneurship). Most management research in this area studies the entrepreneurs; we explore the institutional conditions which frame the likelihood of entrepreneurial engagement. We name these conditions ‘crescive’ and, following A.O. Hirschman's studies on institutional conditions for development we identify two analytically different sets of conditions: those that can stir up actors' motivations to engage and those that can alter their decision making logic. Our exploration of crescive conditions yields a novel conceptual model for entrepreneurial engagement in the context of complex social problems, which we label ‘crescive entrepreneurship’ and place in a space between functionalist and institutional action.  相似文献

We study the issue of optimality of policies devoted to environmental goals, building upon the recent and interesting work by Alesina and Passarelli (2010) and extending their analysis to the more general framework set up by Weitzman (The Review of Economic Studies 41: 477-491, 1974). We illustrate instruments that governments have at their disposal to reduce polluting emissions, and we point out the economic implications that may arise from the overlapping regulation through both instruments in the European context. We review the literature on political determination of environmental regulation. On the basis of existing literature, we show that political factors are more important than economic ones in explaining why particular instruments are implemented for certain problems (Hepburn et al. Climate Policy 6: 137–160, 2006). We recognize Alesina’s contribution which states that environmental policy, and the decision to adopt one tool instead of another, is subject to a complex political process. Governments are subject to pressure from politicians, households, and firms because their decisions imply winners and losers. Then, we focus in detail on the work by Alesina and Passarelli (2010) who consider which policy tool and at what level would be chosen by majority voting to reduce polluting emissions; they find out that even if a tax is in general superior to quantity based mechanisms (quotas and tradable permits), the majority may strategically choose a quantity mode in order to charge the minority a larger share of the cost for polluting emissions reduction. We extend Alesina’s analysis, focusing on the optimality of price-based mechanisms, since it is not always the case that price instruments are more efficient than quantity instruments. To this aim, we explicitly make use of Weitzman results (The Review of Economic Studies 41: 477–491, 1974), which suggest that if costs are highly nonlinear compared to benefits, then price-type regulation is more efficient, while if costs are close to linear, then quantity-type regulation is more efficient. We cast Alesina’s analysis in the European context, analyzing potential voting outcomes, assuming that EU countries can be arranged according to different criteria. We find that depending on the empirical distribution of voting countries, Alesina’s voting procedure leads to interesting different outcomes.  相似文献

This paper addresses the case of the Professional Institute of the Southern Region (IPRES), an institute of higher education in the State University of Morelos, with the aim of showing the measurement results of organizational climate before and after the change of the principal to know some internal features and describe the organizational climate of workers' perception in a transition stage; besides, the influence of the current director's leadership is analyzed in the achievement of organizational goals and how the perception of organizational climate or working environment can be affected by female leadership is also dealt with. In Mexico, there are more and more women running various organizations, including those belonging to the field of education, and universities are no exception. On the other hand, the type of leadership being exercised can promote or hinder the proper performance of the institute and may be a factor of distinction and influence the behavior of those who integrate it; therefore, knowing how it works provides feedback about the processes that determine organizational behavior and the working environment.  相似文献

In this paper we analyse the relationship between governance and learning in clusters and networks. In particular, we see these two key elements as interdependent, suggesting that, under particular circumstances, such interdependence may drive clusters and networks towards a dynamic development trajectory. A pure ‘governance perspective’ makes the development of any locality dependent on the system of powers which exists within the locality or across the global value chain. In parallel, a pure ‘competence-based approach’ focuses mainly on the capabilities of actors to learn and undertake activities. In contrast, we open the prospects for an interdependent relation that may change the actual competences of actors as well as the governance settings and dynamics in networks and clusters. When supported by public policies, the learning process may have the potential to modify the governance environment. Simultaneously, the learning process is intrinsically influenced by economic power, which may seriously affect the development prospects of clusters and networks. This is why an intertwined consideration of both aspects is necessary to promote specific approaches to learning and to design appropriate policies. In this paper we offer two preliminary case studies to clarify some of these dynamics: the first taken from the computers cluster in Costa Rica and the second from an Italian bio-pharmaceutical firm and its production network. The first case study refers to the software cluster that was created from scratch in Costa Rica thanks to an enlightened government policy in coordination with new local enterprises and an important foreign direct investor; while the second reflects on the ability of an individual company to create a network of relationships with large transnational companies in order to acquire new competences without falling into a subordinate position with respect to its larger partners.  相似文献
