This article presents the results of the excavation of a residence dated between the second and fourth centuries AD, constructed over the ruins of the South Arabian town of Makaynūn, in central Hadramawt (Yemen). The building yielded a large quantity of material including objects proving contacts between the central Hadramawt and regions located to the north‐east, such as central Oman, the Gulf area and India.  相似文献

The shift from the linear to the innovation system-based approach has resulted in the emergence of differentiated regional innovation policy. However, certain common presumptions bind these location-specific policies together. The set of information that is used to design these policies and the set of information excluded are fairly similar. The theoretical sections of this paper provide a critical review on the informational basis of regional innovation policy by contrasting the interpretations of the welfare effects of technological change in the utilitarian tradition and in Sen's capability approach. The empirical sections analyse the correspondence of the innovation capacity and welfare (well-being) situation in a Hungarian micro-regional data set. We conclude that the conventional informational basis of innovation policy is too narrow from a welfare perspective. Not only should the differences in the innovation systems, but also the peculiarities of the region's welfare situation be considered during the design of innovation policy.  相似文献

This article examines the complexity and diversity of women's informal financial practices using data from surveys conducted in Senegal. It suggests that these practices are at the centre of a constant dialectic between short‐term and long‐term horizons, between the requirements of daily survival and the demands of community solidarity, and between personal aspirations and collective constraints. These practices also clearly illustrate a desire among the women in Senegal to impose a form of financial self‐discipline, and to create situations that will oblige them to earn income. The socio‐economic diversity among these entrepreneurs is also underscored. Informal financial arrangements are both a product and producer of gender inequalities and inequalities among women, as reflected in the research. This has direct policy implications, especially for microfinance products. If they are to be effective, microfinance services must develop beyond a standard, one‐size fits all model and become more innovative and adaptable to the diverse demands of women. They must be combined with complementary measures that challenge the systemic causes of inequality. Microfinance programmes should draw on informal financial arrangements while challenging their tendency to perpetuate inequality.  相似文献
