In this paper we introduce a minimalist hypothesis for keywords extraction: keywords can be extracted from text documents by considering concepts underlying document terms. Furthermore, central concepts are individuated as the concepts that are more related to title concepts. Namely, we propose five metrics, that are diverse in essence, to compute the centrality of concepts in the document body...

•Extending our previous work on visual keywords, we use the concept of template-based visual keywords using MPEG-7 color descriptors. MPEG-7, also called the Multimedia Content Description Interface, has been a standard for many years. These color descriptors have the ability to characterize perceptual color similarity and need relatively low complexity operations to extract them, besides being...

Along the global trend of economic development, it is often observed rapid industrial transformation accompanied by contitual rural-urban migration. In many developing countries there are yet abundant supplies of “surplus labor.”We construct a small open, dynamic framework to examine how the existence of this large supply of rural, unskilled labor a¤ects trade, urbanization, capital accumulatio...

The classical Heckscher-Ohlin-Mundell paradigm states that trade and capital mobility are substitutes, in the sense that trade integration reduces the incentives for capital to ‡ow to capital-scarce countries. In this paper we show that in a world with heterogeneous …nancial development, the classic conclusion does not hold. In particular, in less …nancially developed economies (South), trade a...

Recently, and due to Arab spring and terrorism around the globe, pushing and driving most governments potentially to harmonize their border measures particularly the regional and an international transit trade within and among Customs Unions. The main purpose of this study is to investigate and provide an insight for monitoring and controlling the trade supply chain within and among different c...

 In this paper, optimum procurement policy is worked out when trade credit is offered to the retailer by the supplier and demand is stock-dependent. The own warehouse (OW) capacity is limited and excess inventory is stored in rented warehouse (RW). The rented warehouse has modern infra-structure facility. Hence, the unit holding cost in rented warehouse is assumed to be higher than that in the...

We show that explicit cartels can implement market share allocations using a reporting framework that is considered to be legally acceptable for trade associations. This simple resolution of the market share cartel’s monitoring problem provides an explanation for the apparent prevalence of market share allocations relative to customer or geographic allocations by explicit cartels. Keywords: exp...

The request for a sustainable development challenges both managers and consumers to rethink habitual practices and activities. While consumers are challenged to develop sustainable consumption patterns, companies are asked to establish managerial systems and structures considering economical, ecological, and social issues. As this is in particular true for housing associations, this paper aims ...

Preferential trade agreements (PTAs) have become an increasingly prominent feature of the international trade environment, with salient examples being the widening and deepening of the European Union (EU), the success of the Mercosur, and the formation of the North American Free Trade Association (NAFTA). In fact, a majority of the active agreements notified to gatt through 1995 were signed in ...
