Egypt comprises thousands of small geographic units. Total fertility rates are reconstructed for the 4905qism, qarya, medina, markaz andshiyakhat covering non-desert Egypt at the 1960, 1976, 1986 and 1996 censuses. This fine spatial scale reveals that heterogeneity across subdivisions increased during the fertility transition, illustrating the rapidity of change. Spatial patterns appear in the fertility upsurge of 1974–85, which is accompanied by a large but temporary reduction in heterogeneity. Fertility varies greatly between subdivisions and geographic differentials underlie the expected and observed association between fertility, literacy, family transfers and industrialization. Cairo led the decline of fertility, but that decline is counterbalanced by rapid economic growth and persistently high levels of illiteracy. A similar pattern of fertility change is observed for the chief city of the Muhafaza and its surrounding area. Egypt presents an archetype of demographic transition as improved economic and educational status diffuses across the country, moderated by its specific geography.  相似文献

Quality certification, regulation and power in fair trade   总被引:2,自引:1,他引:1  
This article examines governance changes and shifting power relations within the fair-labelling network. These shifts are framed analytically by reference to broader changes in the agrofoods sector tied to the increasingly key role played by quality relations and standards in the production and marketing of food. The author argues that evident trends such as a growing complexity of fair-labelling markets, the centralization of its regulating bodies, and the normalization of certification processes have altered power relations to the detriment of small producers. In addition, and at the same time, this ‘fair’ market niche has become more desirable to dominant market actors leading to a combination of factors that has triggered a broad debate within fair trade with respect to the definition and mission of the fair-trade network.  相似文献

Aid fragmentation is a maddening problem in the aid business. NGOs are part and parcel of this fragmentation problem; hence calls for more complementarity between Northern NGOs and (their) governments have led to a series of co‐funding reforms. This article analyses the co‐funding reforms of the Nordic+ donors and situates them within the broader evolutions that have taken place in donor‐NGO relations in these countries. It finds that these donors have interpreted complementarity in very different and even contradictory ways. Where some require NGOs to develop activities within the confines of the official bilateral strategy (intensive complementarity), others allow NGOs to do very different things (extensive complementarity).  相似文献

This paper presents a three-phased local search heuristic CPP-P\(^{3}\) for solving the Clique Partitioning Problem (CPP). CPP-P\(^{3}\) iterates a descent search, an exploration search and a directed perturbation. We also define the Top Move of a vertex, in order to build a restricted and focused neighborhood. The exploration search is ensured by a tabu procedure, while the directed perturbation uses a GRASP-like method. To assess the performance of the proposed approach, we carry out extensive experiments on benchmark instances of the literature as well as newly generated instances. We demonstrate the effectiveness of our approach with respect to the current best performing algorithms both in terms of solution quality and computation efficiency. We present improved best solutions for a number of benchmark instances. Additional analyses are shown to highlight the critical role of the Top Move-based neighborhood for the performance of our algorithm and the relation between instance hardness and algorithm behavior.  相似文献

Gathering large-scale data on tax evasion is an undisputable challenge in and of itself. Doing so in a country in transition from a communist to a democratic system is even more difficult. This paper discusses the challenges and presents a case study to show how they can be dealt with effectively. One important implication of the paper is that such a sample survey can be successful if it combines a careful sample design, research method and questionnaire design, and explicitly takes country-specific institutional and cultural features into account. ‘‘Data!

The highly masculine sex ratio in India has increased substantially in the twentieth century, in contrast to most other countries in the world. Competing arguments alternatively posit under-enumeration, highly masculine sex ratios at birth, or excess female mortality throughout the life course as the factors underlying the level of the overall sex ratio; these arguments have not been resolved. Based on population projections that simulate population dynamics, our findings show that small differences in mortality at young ages, persisting over a long period, as well as a sex ratio at birth of 106 males per 100 females, result in a highly masculine population sex ratio.  相似文献

Problem

Low socioeconomic status and prior negative life events are documented risk factors for antenatal anxiety and depression, preterm birth and birth weight. We aimed to asses whether the adverse effects of prior negative life events increase with lower socioeconomic status and which aspects of socioeconomic status are most relevant.

Methods

We performed a population-based cohort study in the Netherlands including 5398 women in their first trimester of pregnancy. We assessed the number of negative life events prior to pregnancy, aspects of paternal and maternal socio-economic position and symptoms of anxiety and depression. Associations of the number of prior negative life events with anxiety, depression, low birth weight and gestational age were quantified.

Findings

The number of prior negative life events, particularly when they had occurred in the two years before pregnancy and maternal aspects of low socioeconomic status (educational level, unemployment and income) were associated with antenatal anxiety and depression. Furthermore, low socioeconomic status increased the adverse effects of prior negative life events. Obstetric outcomes showed similar trends, although mostly not statistically significant.

Discussion

Low socioeconomic status and prior negative life events both have an adverse effect on antenatal anxiety and depression. Furthermore, low socioeconomic status increases the adverse impact of prior negative life events on anxiety and depressive symptoms in pregnancy.

Conclusion

Interventions for anxiety and depression during pregnancy should be targeted particularly to unemployed, less-educated or low-income women who recently experienced negative life events.  相似文献

Whereas prior research focused on the beneficial effects of time spent with others, this study investigated the association between solitary time and mental health by hypothesizing about the possible detriments as well as benefits. Additionally, we studied whether the association between solitary time and mental health was nonlinear and moderated by gender and life stage. We hypothesized that whereas solitary time limits individuals’ access to social resources and support (decreasing mental health), it also helps individuals to recharge (enhancing mental health). We used the Dutch Time Use Survey from 2006 (N = 1,487). Results of Tobit models indicated that more solitary time in leisure (but not household labor) was associated with a reduction in mental health. For men, we did find a negative association between alone time in household labor and mental health. There was no evidence for a curvilinear relationship between time alone and mental health, nor did life course stage appeared to moderate this association.  相似文献
