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.     

GENDER,SOCIAL NETWORKS,AND RESIDENTIAL BURGLARY*

Criminological researchers have devoted substantial attention to the nature and dynamics of residential burglary, but the role played by gender in shaping this offense remains largely unexplored. Feminist ethnographers have documented the fact that streetlife is highly gendered, and that this typically serves to marginalize women's participation in criminal networks and activities. Therefore, it appears likely that residential burglary—a prototypically social offense that requires good network connections—will be strongly influenced by gender dynamics. In this study, we analyze in‐depth, semi‐structured interviews with 18 female and 36 male active residential burglars to examine the ways in which gender structures access to, participation in, and potential desistance from, residential burglary. In doing so, we aim to provide an insider's view of how gender stereotypes are expressed, reinforced, and exploited within streetlife social networks, and how these networks shape the lived experience of men and women engaged in residential burglary.     

Digital evidence from peer-to-peer networks

In this paper we examine the legal aspects of the forensic investigation of peer-to-peer networks. Organisations may encounter instances where employees have used peer-to-peer software for a variety of types of computer misuse including the dissemination of copyrighted materials or indecent images, or instances where peer-to-peer software has been involved in the transmission of malware for malicious or criminal purposes. In this paper we examine the process of the forensic investigation of peer-to-peer networks, and the issues relating to obtaining digital evidence from such peer-to-peer networks.     

THE ROLE OF NEIGHBORHOOD CONTEXT IN YOUTH CO‐OFFENDING

Despite co‐offending being a core criminological fact, locating suitable peers has many challenges. Chief among these, given the risky nature of co‐offending, is finding trustworthy accomplices. We propose that neighborhoods serve as youths’ most ready source of accomplices, and as such, their composition affects the likelihood of identifying suitable co‐offenders. In particular, youth are more likely to co‐offend in contexts with more peers of their race/ethnicity, less disadvantage, and greater residential stability—all of which promote trust among neighbors. We test our hypotheses using multilevel models applied to census data and official court records for 7,484 delinquent youth in a large metropolitan area. The results offer support for our hypotheses and provide greater insight into how individual and contextual factors combine to affect co‐offending behavior. An implication of these findings is that many of the same neighborhood characteristics that reduce crime lead to a greater proportion of co‐offending.     

Scanning for patterns of relationship: analyzing kinship and marriage networks with Puck 2.0

The article presents the software Puck (Program for the use and computation of kinship data), a computer tool for the in-depth analysis of kinship networks. Its core feature consists in identifying, counting and classifying matrimonial circuit structures (resulting from marriages between kin or affines). Such matrimonial censuses make it possible to explore in a rigorous fashion one of the most central questions in kinship studies: the relationship between particular marriage choices and the patterning of the global kinship network that emerges from them. At the same time, Puck constitutes a general tool for the management, treatment and exploratory analysis of genealogical datasets, including non-genealogical relations and random simulations. Puck has been designed to meet two complementary expectations: the identification of the recurrent, cross-cultural organizational properties of kinship networks, and the ability to situate particular actors within social processes involving both genealogical and non-genealogical factors. This article presents the theoretical foundations and main functions of Puck, using concrete examples drawn from a genealogical dataset of upper-class Parisian Jewish banking dynasties present in Paris during the nineteenth century.     

Strong and weak family ties revisited: reconsidering European family structures from a network perspective

Family systems appear to be an important factor framing people's individual behavior. Thus far, family systems have been primarily addressed on a macro regional level with indirect measures. Revisiting Reher (1998) and the family ties criterion, the main question of this paper is to examine to what extent we perceive family structures differently in Europe by taking direct measures of the structures of people's broader social networks into consideration. Based on the Survey of Health, Ageing and Retirement in Europe (SHARE), we derived two indicators of family regimes based on individual-level data regarding the density of ego social networks: contact frequency and geographic proximity among network members. We aggregated these data and mapped them on the NUTS 2 level regions for various locations in Europe. The results of our analyses exhibit that, based on these two network indicators, significant differences in family structures between European regions exist. These results confirm the classification of strong family Southern and comparatively weaker family Northern European regions to a large extent, though substantial regional differences in and between countries are also revealed. Our findings demonstrate that the classification of European regions largely depends on which indicator of network density we consider. This is particularly obvious in the Eastern European regions where the classification markedly differs according to the type of network indicator. Intriguingly, social networks in Central European regions can be characterized as rather loose, often even looser than the ‘traditional’ weak ties in Scandinavia. Family regimes can, therefore, be regarded as a construct of multiple dimensions of which one dimension may be classified as weak while the other can be strong at the same time.     

Narco-Territoriality and Shadow Powers in a Peruvian Cocaine Frontier

ABSTRACT

Whereas cocaine kingpins are often portrayed as key protagonists and perpetrators of violence in Latin America, in Peru’s Upper Huallaga they are also important powerholders who have formed dynamic systems of governance by dominating socio-economic resources and legitimating their narco-territoriality through arrangements with a variety of “shadow powers.” Although potentially violent armed actors, whether insurgents or the police and military, often abound in these “dangerous places,” in the post-conflict Upper Huallaga most of these groups aimed to gain more power and control by forming coalitions with the local powerholders. Drawing upon the narratives of drug barons, traffickers and producers, insurgents, and state officers, this article seeks to focus on an aspect that is largely overlooked in other analyses: the intricate relationship between contested narco-territoriality, weakening local governance networks, and “new” outbreaks of violence.     

The Effects of Network Expertise and Biases on Vote Choice

Many citizens lack the political knowledge to make informed decisions partly due to the high costs of becoming informed. Previous scholars have argued that if individuals speak with political experts who share their preferences, they can vote as if they were informed without paying information costs. This view of citizens as single-minded seekers of low-cost information is unrealistic. Individuals often choose discussion partners for reasons unrelated to politics, and many communication networks have heterogeneous information levels and preferences as a result. This paper simulates the votes of hypothetical electorates with different individual and network information levels. It demonstrates that network expertise has an effect on vote choice, but this effect is not as large as the effect of individual expertise. Rather, the key contextual determinant of an individual's vote is the partisan composition of his or her discussion network.     

Expanding the Conversation: Multiplier Effects From a Deliberative Field Experiment

Do formal deliberative events influence larger patterns of political discussion and public opinion? Critics argue that only a tiny number of people can participate in any given gathering and that deliberation may not remedy—and may in fact exacerbate—inequalities. We assess these criticisms with an experimental design merging a formal deliberative session with data on participants’ social networks. We conducted a field experiment in which randomly selected constituents attended an online deliberative session with their U.S. Senator. We find that attending the deliberative session dramatically increased interpersonal political discussion on topics relating to the event. Importantly, after an extensive series of moderation checks, we find that no participant/nodal characteristics, or dyadic/network characteristics, conditioned these effects; this provides reassurance that observed, positive spillovers are not limited to certain portions of the citizenry. The results of our study suggest that even relatively small-scale deliberative encounters can have a broader effect in the mass public, and that these events are equal-opportunity multipliers.
