Abstract. Values and ideologies seem to be changing rapidly in many countries of Western Europe. These developments imply a shift among the adherents of political parties. On the one hand, we expect to see a process of deideologization weakening the traditional ties between parties and their adherents. On the other hand, increasing pluralization is suggested by the ongoing process of individualization. In this study we analyze the orientations of the adherents of the main political parties in 12 Western European countries in the last two decades. We expect to find clear traces of ongoing deideologization as well as pluralization, but this expectation proves to be inaccurate. Neither deideologization nor pluralization can be accepted as a common feature of party adherents in advanced industrial societies. On the contrary. Each of these processes seems to follow a different path of development in distinct countries and in distinct party families. A general 'decline-of-the-party' or an 'end-of-ideology' is not to be found among the adherents of the main parties in Western Europe in the last decades. The processes appear to be more complicated, with divergent developments in different countries. 相似文献

This paper uses an augmented Solow model, with cross section data, to measure the effect on per-capita income of a) the entrenchment of various rights in a country's constitution and b) the level of economic freedom in a country, broadly construed. The results suggest that entrenchment,per se, of any single right seldom has a significant general economic effect, while the effect of economic freedom is significant and substantial. The paper then considers whether such evidence could support the proposition that “constitutions do not matter.” While it concludes otherwise, it does caution against incurring excessive negotiation costs to obtain entrenchment of a comprehensive “wish list” of rights. 相似文献

Body image and weight loss beliefs and behaviors were assessed in 341 female and 221 male high school students. Estimates of body dissatisfaction varied depending on the measurement strategy used. Despite having similar weight distributions around the expected norm, girls were significantly more dissatisfied with their bodies than boys. Body Mass Index was positively related to body dissatisfaction in girls and boys, while higher exercise levels were related to higher body satisfaction in boys. Nearly two-thirds of girls and boys believed being thinner would have an impact on their lives, but the majority of girls believed this would be positive while the majority of boys believed this would be negative. Thirteen percent of female subjects reported using one or more extreme weight loss behavior at least weekly. Beliefs regarding the effectiveness of different weight loss measures were assessed. Weight loss behaviors in this Australian sample appear similar to comparable U.S. samples.Received Ph.D. from University of Tasmania.

Undergraduate adult children of alcoholics (ACOAs; N=57) were compared to children of nonalcoholic parents (CONAs; N=100) on measures of the Beck Depression Inventory (BDI), selfesteem, and attributional style. ACOA status was determined using the Children of Alcoholics Screening Test (Jones, 1981). ACOAs were found to have significantly higher scores on the BDI and to have significantly lower self-esteem, as measured by the Index of Self-Esteem, than CONAs. ACOAs were also more likely to have a depressive attributional style, in that they perceived failure as more internal, stable, and global than CONAs. Further, females had significantly higher BDI scores than males.Received B.A. from West Virginia University.

This study examined the influence of pubertal timing upon family interactions in normal and psychiatric adolescent samples. An important feature of our approach is its emphasis upon micro-analysis of family behaviors (individual speeches) and family processes (theoretically specified speech pairings). Rather than assume that global family patterns (e.g., power) shift in response to pubertal changes, we follow how types of speeches and speech sequences are associated with different pubertal timing. Using the previously constructed family coding system, the Constrainig and Enabling Coding System, we found that on-time adolescents and their parents differed from both off-time groups (early or late). These results are discussed in terms of current implications and suggestions for future research.An earlier version of this paper was presented at the SRCD Study Group on Timing of Maturation, October, 1983, at the Education Testing Service, Princeton, NJ.
