The author assesses Taiwan’s fifth competitive national election and its first ever nonsupplementary election. The electorate picked a “new” National Assembly, absent those elected on the mainland before 1949 or later appointed to fill vacancies. The election was a major victory for the ruling Nationalist Party or Kuomintang (KMT) affording it perhaps its first real mandate — a product of the KMT’s good reputation for engineering economic development and in recent years political development as well (since it was largely responsible for getting the “elder parliamentarians” to retire). In addition, the opposition Democratic Progressive Party made a mistake by putting Taiwan independence into the platform. Two other parties contested the election but failed to win a significant number of votes. The new National Assembly will amend the nation’s Constitution which will make some important changes in Taiwan’s polity.  相似文献

We conducted a short-term longitudinal study examining the structure of coping behavior and the relationship between coping style and depression during adolescence. The sample consisted of 603 adolescents in Grades 6–11 who were surveyed in the fall of 1989 and again in the fall of 1990. A two-dimensional model of coping was found using confirmatory factor analysis with the factors being approach and avoidant coping. Four cross-sectional and seven longitudinal coping groups were formed to explore group differences in depression. Approach copers reported the fewest symptoms of depression, while avoidant copers reported the most. Subjects who changed over time from approach to avoidant coping evidenced a significant increase in depressive symptoms, whereas subjects who switched from avoidant to approach coping displayed a significant decrease in depression over a one-year period. These findings imply that adolescents who are able to elicit social support, engage in problem solving, and cognitively restructure events within a positive light are more likely to successfully negotiate the challenges of adolescence.This research was supported by a grant from the William T.

Explored the influence of life stress as mediated or moderated by locus of control, family environment, social support, and coping style on psychological adjustment and school performance in 164 ninth graders from Baltimore. Gender differences in findings were shown. For boys, family cohesion was the only variable found to protect against the effects of stress. Family cohesion did not serve protective functions for girls, and along with overall social support, was associated with increased vulnerability to school problems. The report of problem-focused coping strategies exerted a number of protective functions for girls only. External locus of control was found to increase boys' and girls' vulnerability to the effects of life stress. Empirical development of interventions to improve the psychosocial adjustment of inner-city adolescents is discussed.Received Ph.D. from Virginia Polytechnic Institute and State University in 1991.

Federalism, as a concept and as a reality, received assistancefrom a variety of sources during 1994–1995. Opinion pollsrevealed a public strongly supportive of shifts in the balanceof power between federal and state governments. The new Republican-controlledCongress, bent on devolving authority to the states, busieditself with an ambitious legislative agenda. The DemocraticPresident pursued his principles of federalism and intergovernmentalrelations by supporting the unfunded mandates bill and by increasingthe use of the administrative waiver. The U.S. Supreme Courtbolstered federalism with its rulings in cases such as Lopez,a state challenge to the federal Gun-Free School Zones Act.The new mood in Washington, D.C. was complemented by state leadersanxious to take on the challenges of a rebalanced federal system  相似文献

Government 'strength' and budget deficits in advanced democracies   总被引:2,自引:0,他引:2  
Abstract. Roubini and Sachs provided the first systematic test of the idea that political structure the size, composition, diversity, and/or stability of a governing cabinet - is related to budget deficits. In this paper, we take issue with several of Roubini and Sachs' choices concerning data and operationalization, and argue that their approach cannot offer clear conclusions about the relationship between national political structure and budget deficits. We test the 'strength of government' hypothesis using central government finance data on 16 countries, 1959–1990. We measure deficits in a way that maximizes comparability across countries but avoids the potential problems of standardizing by GDP. We examine carefully the definition and measurement of 'strength of government', in light of recent theoretical and empirical work in comparative politics. We perform pooled time-series regression analysis of deficit change in 16 OECD countries for the period 1959–1990. We argue that while structural differences between governments may have little impact on deficits during good economic times, they may become especially noticeable and influential during periods when governments struggle to cope with severe economic problems.  相似文献
