Thailand is the world’s largest producer of cultured shrimp. Despite problems with poor environmental conditions and outbreaks of disease that have led to the large-scale abandonment of culture areas along the coast, production has remained high. A primary factor has been the establishment of marine shrimp farming in Thailand’s rice growing Central Plain. This paper describes the development of inland shrimp farming in Thailand, and discusses the environmental concerns that have arisen. We then examine the evolution of the government’s response to inland shrimp farming and assess the capacity of the state to implement a proposed ban. We conclude by arguing that other countries with irrigated agriculture need to be proactive in prohibiting this activity before it is entrenched in ways that are difficult to reverse either ecologically or politically. 相似文献

The purpose of this research is to investigate individuals' preferences for visual as opposed to verbal information and to explore how those preferences relate to processing style personality traits. In comparison to individuals with other processing style personality traits, individuals with a high need for cognition prefer to process verbal information while individuals with a high need for affect prefer to process visual information. Linking processing style personality traits with preferences for visual/verbal information increases our theoretical understanding and practical applicability of personality traits. 相似文献

We analyse the interaction between university professors’ teaching quality and their research and administrative activities. Our sample is a high-quality individual panel data set from a medium-size public Spanish university that allows us to avoid several types of biases frequently encountered in the literature. Although researchers teach roughly 20% more than nonresearchers, their teaching quality is also 20% higher. Instructors with no research are 5 times more likely than the rest to be among the worst teachers. Over much of the relevant range, we find a nonlinear and positive relationship between research output and teaching quantity on teaching quality. Our conclusions may be useful for decision-makers in universities and governments. 相似文献

Eagles and Turkeys: Human Capital Externalities,Departmental Co‐authorship and Research Productivity
Lucas (1988) hypothesised that human capital externalities explain persistent productivity growth and become manifest via interactions between workplace colleagues. Consistent with the first part of this hypothesis, Fox and Milbourne (2006) concluded that an increase in the average level of human capital in Australian economics departments raised the research productivity of departmental members. This paper tests the robustness of this finding by using a direct, rather than a proxy, measure of human capital and confirms the existence of human capital externalities within Australian economics departments. But we extend the analysis in two important dimensions. Firstly, we investigate the second part of Lucas' hypothesis by testing whether the externality becomes manifest via co‐authoring. We find no evidence that this type of interaction is associated with higher research productivity, especially for higher quality outputs. Secondly, we control for the likely endogeneity of one's peer group via instrumental variables estimation. In this case, we find that the peer group effect disappears completely for the highest quality outputs but remains for research output more broadly defined. 相似文献

Abstract:Faced with home foreclosures, a stagnant economy, and weakly-effective federal programs of relief, Richmond, California, considered using eminent domain to acquire mortgages, modify loans to be more affordable, and thus prevent further erosion of the tax base. Strong objections have been lodged against such alteration of property rights, except through bankruptcy and foreclosure processes. The Richmond proposal is considered in the historical context of changes in the use of eminent domain as described by John R. Commons. Just as economic change forced U.S. courts to change the working definitions of property in the late nineteenth century, current contradictions in the way in which we think of households, and the systemic consequences of their management of debt, may produce changes in law and should alter the way in which economists analyze aggregate consumer spending and borrowing. 相似文献

This work aims to explain firms’ decisions to adopt Internet-based e-commerce, and the extent to which the adopters subsequently
implement e-commerce to commercialize their products and services. We examine various types of factors previously considered
by the literature (competitive environment, organizational characteristics, strategic orientation, innovative capacity, managers’
characteristics, IT equipment possessed and the use made of it). The analytical model developed here on the basis of a sample
of 2,038 firms suggests that the factors influencing the adoption decision are different from those that eventually influence
the results of firms’ commercial operations on the Internet. Likewise, we discuss the contribution of each type of determinant
and the implications.
