This paper applies the theory of team production to thelegislative process and tests the empiricalimplications of that theory using a uniquestate-level data set. Empirically testablehypotheses are derived from the theory,including predictions that free riding willincrease as chamber (or majority) sizeincreases, and that legislativeinstitutions (such as committee structureand staffing levels) can mitigate freeriding. The hypotheses are tested using apooled state-level data set developed fromthe session laws of twenty-three statelegislatures. The empirical results areconsistent with the major hypotheses.  相似文献

We investigated the relation between urban psychosocial stressors and intimacy achievement in a sample of 59 African American, Hispanic American, and White adolescent fathers-to-be. Participants received an intimacy score based on Orlofsky's Intimacy Status Rating Scale. Those with higher cumulative psychosocial stressors had lower levels of intimacy. One psychosocial risk factor, low interpersonal empathy, was significantly associated with intimacy levels. African Americans had lower levels of intimacy than Hispanic or White participants.  相似文献

This paper evaluates the role that partisan politics plays in altering public spending levels. The analysis covers over three decades of data on the developments of the public sectors in 16 OECD countries. The results of the analysis lend firm support to the partisan politics model. Of special note is the distinction between the electorate' and the government' ideological preferences and the dominant role that the former plays. The results also suggest, contrary to conventional wisdom, that partisan political influences have not been eliminated with the tightening of linkages to the international economy.  相似文献

Abramson and Inglehart find a significant trend toward postmaterialist values in Western Europe, which they argue is largely driven by the gradual processes of generational replacement. Clarke, Dutt, and Rapkin argue that this trend is a methodological artifact of the wording of Inglehart's four-item measure of materialist/ postmaterialist values. They claim that because this battery does not include a question about unemployment, in periods of high unemployment respondents tend to choose postmaterialist goals. The long-term trend toward postmaterialism in Western Europe, they argue, results from rising levels of unemployment during the past two decades. Abramson and Inglehart point out that increases in inflation have a short-term impact on decreasing postmaterialism, but maintain that the positive relationship between unemployment and postmaterialism is spurious. As this analysis shows, Clarke, Dutt, and Rapkin find a positive relationship between unemployment and postmaterialism by building a model that has little theoretical justification and that is not robust to changes in specification. As this analysis demonstrates, unemployment is actually linked with support for materialist goals, and the trend toward post-materialism is robust in the face of alternative time frames, models, and specifications. The weight of the evidence demonstrates that the long-term trend toward postmaterialism in Western Europe is driven by generational replacement.  相似文献

First- and second-year findings from a study of the development of disordered eating in pre- and early adolescents are presented. Fifth- and sixth-grade girls (n = 80) and boys (n = 85) were assessed on depression, body image, self-esteem, and eating behaviors and attitudes in Year 1 and again one year later. Weight, height, and pubertal development were also evaluated in Year 1 and Year 2. Gender differences existed on all measures in Year 2 and indicated consistently poorer scores for girls compared to boys. For girls, Year 1 Body Mass Index and pubertal development predicted Year 2 disordered eating. For boys, poor body image in Year 1 predicted Year 2 disordered eating. The importance of identifying early risk factors for eating disorders is discussed.  相似文献

Abstract. Estimates of voting by occupational class are provided for each of 22 regions in the UK for every general election since 1964. These are analysed, using a log-linear modelling strategy, to identify the changing degree of class dealignment and spatial polarisation within the British electorate over the period. The growing regional variability is consistent with expectations regarding the increasing volume of economic voting and the pattern of uneven development in the country: the north-south and urban-rural divides have both widened.  相似文献
