Asia is the world’s foremost capture fishery and aquaculture producer. It is also home to the majority of the world’s fishers and marine fleet (decked and undecked). Consequently, there is every reason to expect that this importance is reflected in national development discourses. This article identifies the socio-economic importance of fisheries in the region in terms of its contribution to primary exports, domestic protein consumption, employment and poverty alleviation. We then analyse national development and poverty reduction strategy documents using a content analysis methodology previously applied to measure the extent to which environmental or forestry issues had been mainstreamed into national policy documents. This enables us to identify those countries that have currently integrated fisheries into the national development discourse – and those that have not. We conclude by proposing two strategies to enable the more effective integration of fisheries into the development agenda.  相似文献

Hybrid Choice Models: Progress and Challenges   总被引:2,自引:1,他引:1  
We discuss the development of predictive choice models that go beyond the random utility model in its narrowest formulation. Such approaches incorporate several elements of cognitive process that have been identified as important to the choice process, including strong dependence on history and context, perception formation, and latent constraints. A flexible and practical hybrid choice model is presented that integrates many types of discrete choice modeling methods, draws on different types of data, and allows for flexible disturbances and explicit modeling of latent psychological explanatory variables, heterogeneity, and latent segmentation. Both progress and challenges related to the development of the hybrid choice model are presented.  相似文献

Filling a gap in the interlocks literature which has been largely centered on the West, we present preliminary data on the pattern of interlocking directorates among the top 200 largest corporations in pre-1997 Hong Kong. Then we identify four separate groups of firms in Hong Kong, and suggest propositions based on the resource dependence perspective on the critical relationships among their interlocking directorates, firm strategies, and performance. These propositions have the potential to form the building block of an emerging research agenda that will shed light on the role of interlocking directorates in an increasingly important part of the world.  相似文献

Polynomial goal programming (PGP) is a flexible method that allows investor preferences for different moments of the return distribution of financial assets to be included in the portfolio optimization. The method is intuitive and particularly suitable for incorporating investor preferences in higher moments of the return distribution. However, until now, PGP has not been able to meet its full potential because it requires quantification of “real” preference parameters towards those moments. To date, the chosen preference parameters have been selected somewhat “arbitrarily”. Our goal is to calculate implied sets of preference parameters using investors’ choices of and the importance they attribute to risk and performance measures. We use three groups of institutional investors—pension funds, insurance companies, and endowments—and derive implied sets of preference parameters in the context of a hedge fund portfolio optimization. To determine “real” preferences for the higher moments of the portfolio return distribution, we first fit implied preference parameters so that the PGP optimal portfolio is identical to the desired hedge fund portfolio. With the obtained economically justified sets of preference parameters, the well-established PGP framework can be employed more efficiently to derive allocations that satisfy institutional investor expectations for hedge fund investments. Furthermore, the implied preference parameters enable fund of hedge fund managers and other investment managers to derive optimal portfolio allocations based on specific investor expectations. Moreover, the importance of individual moments, as well as their marginal rates of substitution, can be assessed.  相似文献

Using a large sample of private debt renegotiations from 1996 to 2011, we report that, even in the absence of any covenant violation, debt covenants are frequently renegotiated. These renegotiations primarily relax existing restrictions and result in economically large changes in existing limits. Renegotiations of specific covenants are a response to both the distance the covenant variable is from its contractual limit and the firm?s specific operating conditions and prospects. Moreover, the borrower?s post-renegotiation investment and financial policies are strongly associated with the covenant changes resulting from the renegotiation. Overall, the findings imply that, even outside of default states, creditors have strong control rights over the borrower?s operating and financial policies, and they exercise these rights in a state contingent manner through covenant renegotiations.  相似文献

This study examines the challenges met by union representatives (URs) who have to reconstruct their traditional role in the context of labour–management partnerships. They are innovators involved in the transition to renewed labour relations. Identity issues and role conflicts are examined through an in‐depth analysis of the process involved in assimilating this new role in unionized organizations. The results suggest that URs subordinate the partner role to the interest representation role. Interviews suggest that this enhanced union legitimacy. Some blurring of traditional social categories such as those of employee or employer is possible to the extent that the relations between the actors are founded on interpersonal relations.  相似文献

FTA and equity addresses the need for multiple stakeholders’ participation in public policy and corporate decision making thus leading to more democratic societies. The need for more participative and inclusive decision making is due to the move from the technocratic nature of decision making towards more democratic processes, which is a result of the transformation of societies and situations as a result of various factors including globalisation, environmental concerns, more knowledge intensive work and lifestyle.The current paper addresses Future-oriented Technology Analyses (FTA) in the context of a better understanding of issues that ought to be considered by the FTA community so that it can support the quest for new forms of governance. The paper has been structured on the discussion of governance around three pillars: socio-cultural evolution, corporate industrial activity and government.Analysis of the relationship between governance and each of the three pillars poses a number of questions to the FTA community that reflect on the potential impacts of FTA activities in governance. Setting a new landscape for the FTA, the paper concludes with those issues where the FTA community is starting to devote attention, as well as those it still ought to consider.  相似文献

The problem of pricing Bermudan options using simulations and nonparametric regression is considered. We derive optimal nonasymptotic bounds for the low biased estimate based on a suboptimal stopping rule constructed from some estimates of the optimal continuation values. These estimates may be of different nature, local or global, with the only requirement being that the deviations of these estimates from the true continuation values can be uniformly bounded in probability. As an illustration, we discuss a class of local polynomial estimates which, under some regularity conditions, yield continuation values estimates possessing the required property.  相似文献

Along with other affective and emotional dimensions, passion is at the heart of entrepreneurship. Yet past research on entrepreneurial passion (EP) has been hindered by the lack of a sound measurement instrument. Through a series of empirical studies conducted with samples from relevant populations, we develop and validate an instrument to capture EP and its inherent dimensions. We show that the task-specific dimensions of EP (intense positive feelings toward the domains of inventing, founding and developing, and the centrality of these domains to entrepreneurs' self-identity) are conceptually and empirically distinct from one another, and from other emotions and cognitions known to play a role in entrepreneurship. Our theory and results indicate that proper measurement of entrepreneurial passion incorporates the interaction between entrepreneurs' feelings and identity centrality for each domain. We discuss the implications of our model, instrument and findings for future research on the affective components of innovation and entrepreneurship. We also develop specific guidelines for using our validated instrument in future research.  相似文献
