Are repeatedly victimized households different?

Much recent victimization research has concentrated on predicting who will be victimized, with relatively little concern for the number of events suffered. This study turns to the latter issue by focusing attention on the prediction of repeat victimization. A statistical methodology is employed which allows for the explicit recognition that an initial victimization must occur prior to any repeat event. When applied to property crime information from the 1984 British Crime Survey, we find little evidence that repeat victims have distinctive characteristics compared with single victims. Nevertheless, households with characteristics which protect from victimization, in the sense of giving rise to a low initial risk, have this protection reduced for a subsequent event. Moreover, comparing two households with different risk characteristics, their repeat victimization probabilities are more similar than were those for the initial occurrence.     

WOMEN'S GENDER PERFORMANCES AND CULTURAL HETEROGENEITY IN THE ILLEGAL DRUG ECONOMY

Based on interviews with 32 female drug dealers in Norway, this study investigates different gender performances among women situated in the illegal hard drug economy—a context with strong gendered “rules of the game.” Using grounded theory methods, I have identified four predominant patterns in which women enact their gendered identities being part of the drug economy: performing emphasized femininity in the context of marginalization; performing street masculinity; employing a feminine business model; and last, flexible use of cultural repertoires. The findings suggest that different gender performances among dealers are rooted in variations in the cultural tool kits they have at their disposal. I find that the content of women's cultural tool kits varied with three sociodemographic factors: 1) age, 2) time of entrée to the drug economy, and 3) educational and employment history. Combined, these influenced the type of gender performances the dealers tended to use as well as their position in the drug market hierarchy. The research suggests that those dealers using cultural repertoires flexibly are the most successful as they skillfully employed the model best suited for the context they were in.     

RACE,FRIENDSHIP NETWORKS,AND VIOLENT DELINQUENCY

Although a growing body of literature emphasizes the role of friendship networks and peer relations for youth involvement in violence and delinquency, little research has examined the role of friendship networks in understanding the varying involvement of different racial‐ethnic groups in violence. Using data from approximately 13,000 respondents to the first two waves of the National Longitudinal Study of Adolescent Health (Add Health), we explore the ability of friendship networks to account for the differential rates of violence among racial‐ethnic groups. In addition, we evaluate whether race moderates the degree to which friendship characteristics predict adolescent violence. Findings indicate significant differences in the structure and behavioral orientation of friendship networks across racial‐ethnic identities. Moreover, incorporating characteristics of friendship networks into multivariate analyses accounts for greater involvement in violence among black and Hispanic youths. Network racial heterogeneity and friends' popularity also emerge as particular network characteristics that operate differently for black and white youth.     

股份公司内部权力配置的结构性变革——以股东“同质化”假定到“异质化”现实的演进为视角

传统公司代理理论与制度基于股东"同质化"假定的逻辑基础而展开,"资合性"正是对这一基础的法理化表达。股东"同质化"假定具有人性同质与利益同质之内涵,建构其上的股份公司内部权力配置以资本作为唯一标准,形成了权力定位中的股东会中心主义、权力分配中的股份平等原则和权力运行中的资本多数决原则。但这些权力配置原则所产生的诸多流弊已然昭示出其逻辑基础存在先天缺陷。股份公司股东"异质化"现实已经得到公司理论和实践的有力佐证,并不断催生出股份公司内部权力配置的结构性变革。     

Racial and Ethnic Heterogeneity,Economic Disadvantage,and Gangs: A Macro‐Level Study of Gang Membership in Urban America

There is a lack of macro‐level gang research. The present study addresses this shortcoming by providing a theoretically informed analysis of gang membership in large US cities. More specifically, our goal is to determine whether racial and ethnic heterogeneity conditions the relationship between economic disadvantage and gang membership. Three separate sources of data are used in this study: U.S. Census 2000, Law Enforcement Management and Administrative Services 2000, and National Youth Gang Survey 2002–2006. A series of weighted least‐squares regression models are estimated, finding that both economic disadvantage and racial and ethnic heterogeneity exhibit independent and additive effects on gang membership. In addition, the results show that racial and ethnic heterogeneity has a conditioning relationship with economic disadvantage. Furthermore, our expanded operationalization of the Blau heterogeneity measure indicates that prior research may have underestimated the effects of heterogeneity. The authors discuss these findings in the context of existing gang research and offer directions for future research.     

Heterogeneity of Girls’ Consensual Popularity: Academic and Interpersonal Behavioral Profiles

The present study explored the heterogeneous nature of popularity by investigating subgroups of popular girls (N = 365) in their first year of secondary school (mean age  =  13.05). Cluster analysis revealed the presence of five subgroups based upon sociometric popularity (i.e., those considered likeable by peers) and consensual popularity (i.e., those considered popular by peers), and academic behavioral indices. Two of these groups contained girls who were all nominated as “popular” by classmates, yet the girls in one group displayed very positive academic behaviors (Popular Studious); girls in the other popular group displayed extreme antiacademic behaviors (Popular Disengaged). The remaining groups were Average Popular, Unpopular Disengaged, and Unpopular Studious. External validating measures confirmed the existence of the subgroups, that is, Popular Studious girls were judged by classmates to behave in a prosocial fashion, whereas Popular Disengaged girls exhibited many antisocial behaviors, and were often nominated as bullies. Unpopular Studious girls were often nominated as victims. These findings confirmed the hypothesis that consensual popularity is a heterogeneous concept, and that antiacademic and antisocial girls may still be among the most consensually popular students in secondary schools.Lecturer at the Department of Educational Sciences, University of Amsterdam, Wibautstraat 4, 1091 GM Amsterdam, The Netherlands.

Decision rules,membership and political centralization in the European Union

The decision to enter the European Union is based on a comparison of the costs of staying out and going it alone, and the costs membership. The latter depend on the degree of preference heterogeneity between prospective members and the Union as well as the decision rules employed for “constitutional” decisions. The same calculus guides the decision, by member states, to shift policies up to the Union level, only now the decision rules refer to centrally assigned policies. Preference heterogeneity makes more inclusive rules optimal in either case while at the same time reducing the attractiveness of membership or the centralization of policies to the EU level, respectively. The analysis complements and extends both traditional fiscal federalism literature as well as the more recent political economics literature on federalism.

Intra-party heterogeneity and voter perceptions of party positions

Do voters correctly perceive left-right positions of political parties? This question received considerable attention in the literature in the past decades. Previous research has shown that most voters have somewhat ‘correct’ perceptions of where parties are located on a left-right dimension, but that both individual and party level factors influence how much those perceptions deviate from the real positions. This paper adds to this literature, relaxing the unitary actor assumption and introducing heterogeneity to the analysis. Using data from elite surveys to measure intraparty preference heterogeneity on two dimensions, I demonstrate that voters' misperceptions of party positions strongly increase the more heterogeneous the positions of party elites are on the economic dimension, but not on the sociocultural dimension, and that the effect size depends on how salient this dimension is for the party. The findings have implications for future research on mass-elite linkages, representation, as well as voting behavior.     

The undecided voters and the economy: Campaign heterogeneity in the 2005 British general election

Research and conventional wisdom suggest that undecided voters are especially prone to campaign persuasion. Little has been done, however, in the way of uncovering the decision pathways followed by these voters. In this paper we seek to assess the undecided voters’ alleged campaign susceptibility and, most importantly, to explore which campaign considerations inform their final voting decisions. Our central finding is that their behaviour is driven to a larger extent by economic performance and less by leadership or other valence evaluations. This finding has important implications for parties’ campaign strategies in an era where the ranks of undecided voters are steadily expanding from one election to the other.
