This article examines the policy consequences of the number of parties in government. We argue that parties externalize costs not borne by their support groups. Larger parties thus internalize more costs than small parties because they represent more groups. This argument implies that the public sector should be larger the more parties there are in the government coalition. We test this prediction using yearly time-series cross-sectional data from 1970 to 1998 in 17 European countries. We find that increasing the number of parties in government increases the fraction of GDP accounted for by government spending by close to half a percentage point, or more than one billion current dollars in the typical year. We find little support for the alternative claim that the number of legislative parties affects the size of the public sector, except via the number of parties in government .  相似文献

Relationship schemas are core elements of personality that guide interpersonal functioning. The aim of this study is to examine stability and change in relationship schemas across two developmental epochs—adolescence and young adulthood—in the stories that people tell about their interactions with others. Using the Core Conflictual Relationship Theme Method, relationship themes were coded from semistructured interviews conducted in adolescence and again at age 25. The sample consisted of 40 participants in a longitudinal study of adolescent and young adult psychological development. There was considerable stability in the frequency with which particular themes were expressed in the narratives of adolescents and young adults. Significant changes from adolescence to young adulthood included a decrease in the perception of others as rejecting and of the self as opposing others. Young adults saw themselves and others more positively, and used a broader repertoire of themes in their relationship narratives than they had as adolescents. The basic continuity and particular changes in relationship schemas found in this study are consistent with knowledge about the adolescent-to-young-adult transition derived from other empirical and clinical findings. Relationship schemas may be rich units of study for learning about the development of interpersonal functioning.  相似文献

Previous studies have used probit or logit models to analyze two states of monetary policy (tighter or looser). In this paper we employ multinominal logit to permit Federal Reserve monetary policy to assume one of three alternative states (tighter, looser, or no change) as a function of three independent economic variables (unemployment, real growth, and inflation) and the amount of experience of the Board of Governors. The results indicate that the Federal Reserve reacted differently under Burns, Miller and Volcker and between Volcker's two operating procedures in the formulation of monetary policy.  相似文献

A laboratory study interested in the analysis of human hair for drugs-of-abuse was conducted to determine if drugs could be detected and quantified from hair. Supercritical fluid extraction (SFE) techniques followed by GC-MS analysis were applied to extract amphetamines from hair. The group of amphetamines included methylenedioxyamphetamine (MDA), methylenedioxymetamphetamine (MDMA), methylenedioxyethylamphetamine (MDEA) and internal standard mephentermine (MP). To validate information on amphetamine use in hair, powdered hair samples free from drugs were collected and soaked in a known amphetamine standard solution. Authentic fortified case hair samples taken from known drug users known to have consumed amphetamines were also analyzed for amphetamine. Results from this study show that amphetamine use can be detected in spiked and authentic fortified human hair using SFE techniques for qualitative and quantitative reproducible results.  相似文献

When invited by the organisers of the Asia-Pacific Non-governmental Organisation (NGO) Beijing+10 Forum to make a brief presentation on the question of academic feminists and the de-politicisation of feminist theorising, I asked myself: What politics? What feminist theorising? Then I remembered how close the links were between the history of feminism in academe—particularly in the form of Women's Studies—and the women's movement.2 Vina Mazumdar, ‘Whose Past, Whose History, Whose Tradition? Indigenising Women's Studies in India’, paper prepared for the International Conference on Women's Studies in Asia, Seoul, 18–21 October 2000 published in Asian Journal of Women's Studies, vol. 7, no. 1, 2001, pp. 133–53; Carol Sobritchea, ‘Imaging the Future of Asian Women's Studies and Feminist Scholarship’, paper prepared for the International Conference on Women's Studies in Asia, Seoul, 18–21 October 2000; and Tita Marlita and E. Kristi Poerwandari, ‘Indonesian Women's Movement throughout History: 1928–1965’, paper prepared for the International Conference on Women's Studies in Asia, Seoul, 18–21 October 2000, are recent narratives of the development of Women's Studies and its ties to the women's movement in India, the Philippines, and Indonesia, respectively.

A DNA microarray system for forensic SNP analysis   总被引:3,自引:0,他引:3  
Forensic DNA analysis is routinely performed using polymorphic short tandem repeat (STR) markers. However, for degraded or minute DNA samples, analysis of autosomal single nucleotide polymorphisms (SNPs) in short fragments might be more successful. Furthermore, sequencing of mitochondrial DNA (mtDNA) is often performed on highly degraded or scarce samples due to the high copy number of mtDNA in each cell. Due to the increasing number of complete mtDNA genome sequences available, the limited discrimination power of an mtDNA analysis, may be increased by analysis of coding region polymorphisms in addition to the non-coding variation. Since sequence analysis of the coding region would require more material than generally present in forensic samples, an alternative SNP analysis approach is required. We have developed a one-colour microarray-based SNP detection system for limited forensic materials. The method is based on minisequencing in solution prior to hybridisation to universal tag-arrays. In a first outline of a forensic chip, a combination of 12 nuclear and 21 mitochondrial SNP markers are analysed simultaneously. The mitochondrial markers on the chip are polymorphisms within the hypervariable region as well as in the coding region. Even though the number of markers in the current system is limited, it can easily be extended to yield a greater power of discrimination. When fully developed, microarray analysis provides a promising system for efficient sensitive SNP analysis of forensic samples in the future.  相似文献
