Neighborhoods and Fertility in Accra, Ghana: An AMOEBA-based Approach

Fertility levels remain high in most of sub-Saharan Africa, despite recent declines, and even in a large capital city such as Accra, Ghana, women are having children at a pace that is well above replacement level and this will contribute to significant levels of future population growth in the city. Our purpose in this paper is to evaluate the way in which neighborhood context may shape reproductive behavior in Accra. In the process, we introduce several important innovations to the understanding of intra-urban fertility levels in a sub-Saharan African city: (1) despite the near explosion of work on neighborhoods as a spatial unit of analysis, very little of this research has been conducted outside of the richer countries; (2) we characterize neighborhoods on the basis of local knowledge of what we call "vernacular neighborhoods"; (3) we then define what we call "organic neighborhoods" using a new clustering tool-the AMOEBA algorithm-to create these neighborhoods; and then (4) we evaluate and explain which of the neighborhood concepts has the largest measurable contextual effect on an individual woman's reproductive behavior. Multi-level regression analysis suggests that vernacular neighborhoods are more influential on a woman's decision to delay marriage, whereas the organic neighborhoods based on socioeconomic status better capture the factors that shape fertility decisions after marriage.     

Rational,reverential or experimental? The politics of electoral reform in Oceania

Oceania, with the exception of New Zealand, has received little comparative attention in studies of electoral reform. This article uses evidence from Fiji, Tonga, Papua New Guinea and Nauru, as well as New Zealand and Australia, in order to: understand the process of electoral reform at national and regional levels; examine variation in the process and consider whether theories of electoral reform from elsewhere apply to Oceania. It finds that electoral reform is a highly complex process that is influenced by the self-interest of parties, democratic values and diffusion.

除了新西兰,不大有人从比较选举改革的角度关注大洋洲。本文使用斐济、汤加、巴布亚新几内亚、瑙鲁以及新西兰和澳大利亚的资料,目的是在国家和地区的层面上理解选举改革的过程;探讨过程中的变异,并思考其他地方的选举改革理论是否适用于大洋洲。     

An analysis of Late Pre-Islamic copper-base artefacts from Ed Dur, U.A.E.

The article presents the analytical results of a study of copper-base artifacts from ed-Dur, a large site in the United Arab Emirates which was occupied principally during the 1^st century A.D. In addition to identifying a number of pieces with high lead content, the analyses have contributed to an understanding of brass and brass distribtion in the Roman Near East.
