In contrast to established party systems, the transformation of post-communist party systems is not only shaped by shifts in electoral preferences, but also by the changing organizational loyalties of politicians. Post-communist politicians pursue a wide range of organizational strategies such as party fusions, fissions, start-ups, and interparty switching. By focusing on the interaction between these organizational strategies and voters’ electoral preferences, we argue that the seeming instability of post-communist party systems actually reveals distinct patterns of political change. The article develops an analytical framework, which incorporates politician-driven interparty mobility and voter-induced electoral change. It uses this framework to show that the apparently inchoate party systems of Estonia, Latvia, and Lithuania actually follow definable modes of transformation. Marcus Kreuzer is assistant professor of political science at Villanova University. His work focuses on how electoral and legislative institutions shape the organizational and electioneering practices of parties in interwar Europe and post-communist democracies. He also is studying the origins of liberal democracy in nineteenth century Europe. He is author ofInstitutions and Innovation—Voters, Politicians and Interest Groups in the Consolidation of Democracy: France and Germany, 1870–1939 (2001). Vello Pettai is lecturer in political science at the University of Tartu, Estonia. He specializes in comparative ethnopolitics and party politics. He has published previously inNations and Nationalism, Post-Soviet Affairs, East European Politics and Society, andJournal of Democracy. We would like to thank for Artis Pabriks and Darius Zeruolis for sharing their knowledge of Latvian and Lithuanian party politics as well as John T. Ishiyama, Scott Desposato, and two anonymous SCID reviewers for commenting on an earlier draft. Funding for this research came from an Estonian Science Foundation grant, nr. 4904. We gratefully acknowledge their support.  相似文献

School districts are spending millions on tutoring outside regular school day hours for economically and academically disadvantaged students in need of extra academic assistance. Under No Child Left Behind (NCLB), parents of children in persistently low‐performing schools were allowed to choose their child's tutoring provider, and together with school districts, they were also primarily responsible for holding providers in the private market accountable for performance. We present results from a multisite, mixed‐method longitudinal study of the impact of out‐of‐school time (OST) tutoring on student reading and mathematics achievement that link provider attributes and policy and program administration variables to tutoring program effectiveness. We find that many students are not getting enough hours of high‐quality, differentiated instruction to produce significant gains in their learning, in part because of high hourly rates charged by providers for tutoring. We identify strategies and policy levers that school districts can use to improve OST tutoring policy design and launch improved programs as waivers from NCLB are granted.  相似文献

Abstract

This article examines key arguments on the relations between bodies and images developed in the context of the discursive turn to consider what light a feminist materialist approach might shed on them. Rather than set the discursive and materialist ‘turns’ in opposition to each other, the author tries to draw connections between different theories of the relations between bodies and images, and unpack how certain feminist concerns are approached from different angles in different historical and intellectual contexts. To do this, the author focuses on the prevalence of images of transformation in contemporary visual culture and analyses them in terms of how both ‘new materialist’ and feminist theories grapple with the worlds they engage with, where change and transformation are seen as key. The author takes up three specific and related points that are currently being debated in feminist materialisms: (1) the concept of representation and, more widely, representational thinking; (2) the concept of causation and an understanding of time as non-linear, intensive and inventive; and (3) the understanding of theory as immanent and inventive. Drawing on insights developed in both the discursive and materialist ‘turns’, the author focuses on how bodies and images are entangled together as material assemblages and, in Barad's terms, how theories are performative of the phenomena they seek to understand. The article concludes by suggesting that such an understanding of theory as inventive might be a way of continuing to ensure the animation of feminism's transformative nature.  相似文献

ABSTRACT

Auvergne Doherty was the first woman from the Commonwealth to be admitted and called to the Bar of England and Wales.?In the first part of this article, Doherty's family background, education, legal training, and post-Bar experiences are set out. The second part analyses her profile compared with the other women called to the Bar in 1922 and considers why Doherty may not have gone on to practise as a barrister. This article argues that Doherty’s biography is important because it evidences how vital it was to have the necessary financial means and networks to be able to forget a career at the Bar. It was precisely the lack of these factors that impeded Doherty to fulfil her career as a barrister.  相似文献
