Whether public opinion should be expected to play a role in the shaping of abortion legislation in the states is a debatable question. Representation is a difficult task, especially if legislators receive mixed cues from the public, activists, and the political parties. In this study, we find that grass-roots activism and public opinion tend to match, and both are reflected in state abortion policy. In addition, more Pro-Life policies are found in states with a tradition of conservative policies in other areas, Republican majorities in the state legislature, more Catholic residents, and fewer women legislators. These patterns hold true for a composite index of abortion policies and for the specific policy area of government funding of abortions. Slightly different patterns occur for parental consent laws, though these statutes also tend to reflect general preferences on abortion and interest group activity in a state.  相似文献

This article addresses processes of livelihood diversification among pastoralists in the rangelands of northern Kenya and southern Ethiopia. The objectives of the article are threefold: (1) to suggest a theoretical framework for addressing income diversification among pastoralists with reference to current literature and databases; (2) to present a case study on pastoral income diversification based on preliminary field research in northern Kenya and southern Ethiopia; and (3) to summarize current understandings of pastoral diversification while pointing to additional empirical research needs. By showing how comparative analyses in the region have been constrained by theoretical and data deficiencies, the article explores ways in which income diversification differs by what are termed conditional, opportunity, and local response variables. Climate, distance to market towns, gender, wealth, and education are attributes covered by these variables and discussed in the article. The conceptualization and case study provide useful bases for conducting comparative research on pastoral diversification in East Africa specifically, and in sub‐Saharan Africa generally.  相似文献

Ability to throw was probably achieved at an early stage in human evolution but has received little scholarly attention. Although this ability is poorly developed in apes, anatomical studies suggest that the hand ofAustralopithecus afarensis was adapted to throw with precision and force. Archaeological evidence and early ethnographic observations are cited in order to demonstrate the importance of the throwing skill in human evolution.
Résumé La capacité de lancer a probablement paru assez tôt au cours de l'évolution humaine, mais les savants y ont accordé peu d'attention. Bien que cette habileté soit peu dévelopée parmi les grands singes, des études anatomiques suggèrent que la main d'Australopithecus afarensis était adaptée à lancer avec précision et force. L'auteur cite les indices archéologiques et les anciennes observations ethnographiques afin de démontrer l'importance dans l'évolution humaine de cette capacité de lancer des objets.

The effects of sedentism on economic behavior, with special reference to the activities involved in the exploitation of ceramic and lithic resources, are discussed. The context of the study is the late Neolithic of Southeast Europe. It is argued that the widespread establishment of sedentary communities in the Balkans was followed by changes in the production of pottery and stone tools, entailing the routine investment of increasing amounts of labor in most phases of production, increased complexity in the organization of production, and a more selective approach to resource exploitation. Ceramic and lithic production form an important part of the nonsubsistence side of the Neolithic economy, and an understanding of changes in this sphere of activity is crucial to a comprehension of the wider effects of sedentism on economic behavior.  相似文献
