This article addresses theoretical issues concerning differentiation and class formation using North American data. It explores how socio‐economic characteristics vary and impact survival in agriculture. The study is based on panel data collected from a sample of smallholders in three Piedmont North Carolina counties. Factor analysis reveals five major dimensions of differentiation: scale, household labour, off‐farm family labour and income, demographic characteristics, and land tenure. An index of propensity to survive in agriculture, constructed from three waves of panel data is regressed upon five indices measuring the underlying dimensions of differentiation. Land tenure manifests a statistically significant net effect on survival in agriculture. These empirical results support theoretical arguments in favour of integrating analyses of socio‐economic and demographic differentiation in the study of agricultural enterprises. 相似文献

How did Indian democracy avoid the fate of other Third World democracies that collapsed in the face of distributional conflicts, when such conflicts were in ample evidence in India? The traditional answer is that the inclusiveness of the Indian National Congress during the independence movement gave the party legitimacy after independence and allowed it to contain social conflict. This argument fails to account for the persistence of Indian democracy after the 1960s. This article suggests that the pre-independence Congress did not accommodate challengers from below as is commonly suggested, but rather outflanked them by championing still weaker groups further down the social ladder. This “sandwich tactic” has been used repeatedly by Congress leaders during successive crises and accounts for the party's long innings in power, its continued strength today, and, inter alia, the acquiescence of Indian elites in electoral democracy. 相似文献

For over two decades, the theory of groupthink proposed by Irving Janis has remained the most prominent analysis of group dynamics in policy-making. Suffering from its own popularity, groupthink has become a catch-all phrase without a clear meaning. Moreover, theories of group decision-making—even when applied to public policy-making—have typically ignored political variables, focusing almost exclusively on psychological arguments. This article offers three more narrowly construed propositions about policy-making groups: (1) that extremes in the distribution of power within a decision group reduces the integrative complexity of that group's deliberations and, thus, a leader's ability to learn; (2) that extremes in group size produce similar effects; and (3) that the integrative complexity of deliberations is improved when power concentration is appropriate to group size. An examination of the Reagan Administration's decision-making in two phases of the Iran-Contra affair lends support to these hypotheses and reveals the importance of political structure in decision group dynamics. 相似文献

This paper examines the developmental antecedents of interpartner violence (IPV) victimization and perpetration in a New Zealand
birth cohort (n = 828). The study found: (a) IPV occurred in 70% of relationships, with conflict ranging from minor psychological abuse to
severe assault; (b) men and women reported similar experiences of victimization and perpetration of IPV; (c) exposure to abuse
in childhood, family dysfunction and adversity, childhood and adolescent conduct problems, and alcohol abuse/dependence were
significant predictors of IPV victimization and perpetration at age 25; and (d) the antecedents of IPV were largely the same
for males and females, although the specific effects of these risk factors differed according to gender. Conduct disorder
was more strongly predictive of IPV for females, whereas family adversity was more strongly predictive of IPV victimisation
for males. 相似文献
