Proportional representation systems affect the extent to which elected legislators exhibit various attributes that allow them to earn a personal vote. The sources of variation in personal vote-earning attributes (PVEA) lie in informational shortcuts voters use under different electoral rules. List type (closed or open) and district magnitude (the number of legislators elected from a district) affect the types of shortcuts voters employ. When lists are closed, legislators' PVEA are of decreasing usefulness to voters as magnitude (and hence the number of candidates on a list) increases. When lists are open, legislators' PVEA are increasingly useful to voters as magnitude increases, because the number of candidates from which voters must choose whom to give a preference vote increases. As predicted by the theory, the probability that a legislator will exhibit PVEA—operationalized as local birthplace or lower-level electoral experience—declines with magnitude when lists are closed, but rises with magnitude when lists are open .  相似文献

Summary

Mediating Conflict in the Swiss Diets of the Fifteenth and Sixteenth Centuries

The Helvetic Confederation developed in the fourteenth and fifteenth centuries as a web of alliances between the most important urban and peasant republics (Orte) in the area of present‐day Switzerland. The only form of mediating conflicts laid down in the alliances was by tribunals of arbitration; but these were never recognised by all the Orte in the web of alliances and proved inadequate in the face of growing antagonisms and coalitions throughout the Confederacy. It became necessary to have recourse to political arrangements involving the interested parties. The forum for these arrangements was the Diets, meetings of deputies of all members of the Confederacy. These more or less represented the most important political forces. Difficulties arose only when there was no consensus in individual Orten and when the official deputies to the Diet represented only the magistrates (Obrigkeiten). In such cases it could happen, especially in matters of foreign policy, that individual groups went their own way and thwarted the decisions of the Diet. It usually took a long time to arrive at a consensus in the Diets because the deputies were bound by an ‘imperative mandate’ and the minority would mostly not accept the will of the majority. In the fifteenth and sixteenth centuries participation and the achievement of consensus were the conditions of joint action of the Helvetic Confederation.  相似文献

This article examines the construction of the postwar British family in amateur film with reference to the Sidney Lane and Cecil Scrutton collection held at the East Anglian Film Archive (EAFA), particularly the films covering 1948 – 1961. Heather Norris Nicholson argues that home movies contribute to ‘an understanding of leisure and visual-related practices of consumption as well as the social processes by which people came to give themselves, and others, identities’ in the mid-twentieth century (Nicholson, H. N. [2004]. At Home and Abroad with Cine Enthusiasts: Regional Amateur Filmmaking and Visualizing the Mediterranean, ca. 1928 – 1962’. Geojournal, 49, 323–333). By considering the social and historical contexts in which these home movies were produced, and using accompanying notes by one of the filmmaker’s sons, the leisure time films of Lane and Scrutton can be analysed in order to understand how the amateur cine hobby ideologically constructed family, community and national identity in postwar Britain. The images of Christmas parties, daytrips and holidays in these films reveal much about this particular family, and are therefore very illuminating to the social historian and film scholar of today.  相似文献
