Models of legislative organization frequently begin with the premise that the committee system serves the re-election interests of incumbent legislators. Attempts to substantiate this notion empirically have been unsuccessful. Nevertheless, the notion lives on, nourished by a stylized characterization of the committee system. In the standard model committees have jurisdictional monopolies over specialized policy areas and legislators gravitate toward those committees that deal most closely with the policy concerns of their constituents. Contrary to this simplifying characterization, the degree of monopoly control and policy specialization varies across standing committees in the us congress. Some committees have wide jurisdictions and attract members with diverse policy preferences. Jurisdictional overlap and resulting turf battles are common aspects of congressional sessions. We suggest here that these realities warrant a re-opening of the empirical investigation into the link between electoral success and committee characteristics. Our findings indicate that assignment to a committee with a relatively high degree of monopoly control increases a member's vote share, and that assignment to a narrowly focused (specialized) committee does not. 相似文献

Although there have been several studies of women in legislatures in Canada, a cabinet position is a much stronger position from which to wield power in an executive-centered and party-disciplined parliamentary system. In the past decade, the increase of women's share of legislative seats, for majority parties as well as others, has led to more women being appointed to cabinet portfolios. This article utilizes data from the ten Canadian provinces over an 18-year period, from 1976 to 1994, to assess patterns of such appointments by province, party, percentage of women in the governing party, and percentage of women in the legislature. The proportion of women in the governing party far outweighs other variables in its impact on the percentage of women in the cabinet, in contrast to a previous study of West European cabinets which found that more women in the legislature was of greater importance. Although a high level of multicollinearity indicates caution in attempting to distinguish between the impact of these two variables, the differences in these studies may be due to Canadian provinces having single-party majority governments while West European cabinets are often coalitions. 相似文献

This study used a cluster analytic approach to identify self-esteem trajectories among adolescents over a four-year period from sixth to tenth grades (N = 1,160). Four self-esteem trajectories were identified that replicated previous research: (1) consistently high, (2) moderate and rising, (3) steadily decreasing, and (4) consistently low. Female adolescents were more likely to be in the steadily decreasing self-esteem group while male adolescents were more likely to be in the moderate and rising group. African American and white youth were equally distributed across groups. Using repeated measures analysis, we found that youth with consistently high and moderate and rising self-esteem reported developmentally healthier outcomes in Grade 10 than youth in the other two clusters. Outcomes included susceptibility to peer pressure, school grades, and alcohol use. Implications of these results for studying self-esteem and developmental change more generally are 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

Evaluation practices developed in France, especially by local authorities and above all by regional councils, provide an interesting opportunity to examine from the inside the way public policies are constructed. Taking evaluation practices seriously as a subject of study reminds us, in a way, of the necessary empiricism needed to analyse public policies. At a time when this discipline experiences, at least in France, a surge in conceptual proposals, the point of view expressed here aims to point out the necessary modesty we have to show in the face of the complexity of the subjects studied and of the usefulness of evaluation practices to explain territorial public policies. 相似文献

A method is presented for the numerical analysis of sex differences in size and shape of the proximal humeral outlines using elliptical Fourier functions (EFFs). A skeletal sample consisting of right and left humeri pairs of 69 individuals, 36 males and 33 females, was used. The proximal superior view in the plane of the proximo-distal axis of each humerus was photographed and then 54 boundary points were located on the two-dimensional outline tracings. These points were digitized and used to compute EFFs with 27 harmonics. From the EFFs, a set of expected points on the proximal humeral outline was generated using the centroid as an origin. Superimposition of the male and female outlines on this centroid provided a detailed picture of the relative sex differences in size and shape with respect to that center. The bounded area of the proximal humeral outline showed statistically significant sex differences. Additionally, statistical results of the amplitudes derived from the "area-standardized" EFFs and visual assessments of the mean outline plots indicated significant sex differences in shape of the proximal humeral outlines. Focusing on localized regional differences, the greater tubercle was located more postero-medially and the lesser tubercle was located more anteriorly in the males compared to the females. Sex determinations from the proximal humeri were also examined with discriminant functions based on the amplitudes, which represent shape characteristics of the outline, and the hounded area. Using a cross-validation method, predictions of the percentages of cases correctly classified with the discriminant functions were ranged from 92.8% to 95.7% for the right and left humeral data. These results suggest that differences in size and shape of the proximal humeral outlines may be better predictors of sex when compared with conventional measurements of the humerus. 相似文献
