We investigate the geometrical properties of the target space of the five-dimensional Einstein-Maxwell-Chern-Simons system admitting two commuting spacelike Killing vector fields whose Chern-Simons coupling constant is the non-SUGRA value. Source

This paper analyses the political economy of environmental policies in the presence of an eco-industry pressure group. Previous studies deal with two kinds of lobbiests: capitalists and environmentalists. We introduce into the process a third pressure group representing the eco-industry sector. An incumbent government maximizes its chances of being reelected with an objective function that includes both social welfare and political contributions. Introduction of the eco-industry lobby introduces new political contributions and modifies the incentives of the traditional lobbiests. We suppose an open economy context. In two countries, two polluting sectors are subject to an environmental policy. Therefore, an eco-industry sector that supplies polluting firm abatement goods and services arises. Abatement goods and services are assumed internationally traded, creating the only industrial interaction between the two countries. Pollution affects consumers in both countries and can be transboundary or purely local. Both cases are analyzed. Our main findings can be summarized as follows. Eco-industries will lobby in favor of more stringent environmental policies unless the impacts of foreign competition more than compensate for the increase in turnover that a tighter environmental policy induces. Polluting firms always lobby against tighter environmental policies. © 2015 Japan Section of the Regional Science Association International. All rights reserved. Source

Recent research concerning environmental policies emphasizes a specific characteristic of environmentalists, particular disconcertment about foreign-source pollution. A polluting sector exists where two polluting firms-one at home and the other foreign-strategically compete in a third market. Each government taxes its domestic polluters on the basis of the emissions level. Therefore, each firm invests in pollution abatement to reduce the emissions level. An environmental lobby group in the home country initiates action by offering the foreign government a contribution schedule that specifies the payment to be made to the government as a pollution tax. Taking the contribution schedule, the pollution abatement levels and the production levels of the two firms as given, the government then implements a politically optimal pollution tax. This study investigates the implications of lobbying to the foreign government, when environmentalists are negatively affected by pollution from abroad. We found that the impact of an increase in environmentalism on the politically optimal pollution tax rate depends on(i) whether the pollution is local or transboundary,(ii) the extent to which environmentalists are concerned about pollution in the foreign country and(iii) the marginal cost of investments in pollution abatement by the foreign firm. Moreover, we compared the non-cooperative pollution tax rate with the politically optimal pollution tax rate and found that a differential between the two rates increases as environmentalism increases.

Fuzzy co-clustering is a basic technique for revealing intrinsic co-cluster structures from cooccurrence information among objects and items. In most of fuzzy co-clustering algorithms, objects and items are partitioned based on different constraints. Objects are forced to be exclusively partitioned like as Fuzzy c-Means (FCM), while item memberships often represent just the relative significance of items in each cluster, i.e., items can be shared by multiple clusters. In a previous work, exclusive partition of items were achieved by introducing a penalty term in Fuzzy Clustering for Categorical Multivariate data (FCCM), which is an FCM-type co-clustering with entropy regularization mechanism. In this paper, the applicability of dual exclusive partition of objects and items are discussed in the frameworks of Fuzzy CoDoK and SCAD-based fuzzy co-clustering. © 2013 The Authors. Source
