Knowledge and learning in online networks in development: a social-capital perspective

The authors examine whether the concept of social capital can facilitate our understanding of online networks in development. Much of the knowledge generation and social learning in development takes place in networks, which increasingly operate online. Although these networks are assumed to be a positive force in development, there are many unknown factors, partly because they are in their infancy. The concept of social capital has traditionally been applied to examine the functioning of groups and societies. More recently, it has also been applied to development and to online networks outside development. Three non-development approaches to examining social capital in online networks and communities are reviewed in the article. Elements of these approaches, combined with development-related aspects, are used to produce a framework to facilitate the analysis of social capital in online networks in a development context.     

Race-Specific Gender Equality and Rape: A Further Test of Feminist Hypotheses

Feminists have long argued that structural inequality between men and women influences the prevalence of rape. The patriarchal maintenance hypothesis predicts that gender inequality increases rape, while gender equality ameliorates rape (Whaley and Messner 2002). Alternatively, the backlash hypothesis predicts that gender equality exacerbates the rape problem (Russell 1975; Williams and Holmes 1981). To date, no study has explored this relationship with respect to race. In the present study, we use a cross-sectional design with racially disaggregated census and crime data in order to assess the differences among White and Black women in terms of their status along educational, employment, income, and occupational dimensions, and their risk of victimization. The findings indicate that the relationship between equality and rape is masked in the model that includes all women, but becomes apparent in the race specific models. This revised version was published online in July 2006 with corrections to the Cover Date.     

A predictive model of male spousal violence

This study presents and tests a predictive model of severe marital violence by men based on social learning theory and previous research. Results of the path analytic procedure suggest that sex-role egalitarianism and approval of marital violence both have direct effects on the use of severe marital violence. At the same time, sex-role egalitarianism and the observation of marital violence as a child have indirect effects by several paths. Egalitarianism has an indirect negative effect on use of severe violence which depends upon approval of marital violence. Observation of marital violence has a negative effect on self-esteem which influences marital stress and level of alcoholism, both of which have an effect on approval of marital violence. Observation of violence as a child also has a direct effect on approval of violence and a negative effect on sex-role egalitarianism.     

Constructing the Market: Commercialization and Privatization in the Royal Mail

The public sector in the UK has become the object of constant reform and change as part of the government's project to increase the remit of the private sector and the role of markets. There is much debate about the effect such a move to market relations has on public services. There is increasing concern with the way market–based reforms are linked to a new pattern of organizational structure and strategy that negates and/or opposes the traditional political processes associated with the public sector. This article focuses on the case of the Royal Mail to explore how such a transformation is both complex and contested. It reveals how 'the market' within the public sector is to a large extent politically constructed, and that the public–private dichotomy over–simplifies what is a complex process of negotiating meaning, forming alliances, lobbying for support, handling conflict and exerting influence. It demonstrates how various readings of 'the market' emerge, and that any solutions of how to become more commercial can be the result of political machinations. The implications of this analysis go beyond Royal Mail and can be generalized across the public sector.     

State Actions Affecting Cities and Counties, 1990–1993: De Facto Federalism

States experienced considrable fiscal stress during the first four years of the 1990s. This has led to changes in five policy areas: (1) state financial aid; (2) local revenue diversification; (3) "sorting out" of responsibilities between the state and local governments; (4) tax and spending limitations; (5) and mandate relief. Some of the most significant changes occurred in California, Colorado, Maryland, Massachusetts, Minnesota, New Jersey, Oregon, and Wisconsin.     

Freedom from Fear of Stalking

The attention on stalking – willful and repetitive, sometimes dangerous harassment – and the ways in which legislation can address this issue is investigated. Since the attention on stalking is only a recent development a review is given of the international regulations as well as several opinions about the nature of stalking     

Decision making in joined criminal trials: The influence of charge similarity,evidence similarity,and limiting instructions

The present research investigated decision-making processes in joined trials of multiple offenses. Subjects judged videotaped trials of three joined charges in a factorial design that varied charge similarity, evidence similarity, and judges' instructions designed to reduce judgement biases; or judged one of several charges presented individually. The results indicated that subjects were more likely to convict a defendant in a joined trial than on the same charge tried by itself, particularly when the charge was presented in the third position. Convictions were more frequent when joined charges were similar, and judges' instructions significantly reduced conviction rates. Subjects judging joined trials confused evidence among charges, rated the prosecution's evidence as stronger, and rated the defendent less favorably than subjects judging single trials. The findings were compared statistically to the results of previous research, and it was concluded that increased convictions in joined trials are robust effects.This research is based on part of a doctoral dissertation by S. Tanford at the University of Wisconsin. The research was supported by National Institute of Justice Grant No. 81-LJ-CX-0048 to S. Penrod.     

microRNA Detection in Blood,Urine, Semen,and Saliva Stains After Compromising Treatments

Evaluation of microRNA (miRNA) expression as a potential method for forensic body fluid identification has been the subject of investigation over the past several years. Because of their size and encapsulation within proteins and lipids, miRNAs are inherently less susceptible to degradation than other RNAs. In this work, blood, urine, semen, and saliva were exposed to environmental and chemical conditions mimicking sample compromise at the crime scene. For many treated samples, including 100% of blood samples, miRNAs remained detectable, comparable to the untreated control. Sample degradation varied by body fluid and treatment, with blood remarkably resistant, while semen and saliva are more susceptible to environmental insult. Body fluid identification using relative miRNA expression of blood and semen of the exposed samples was 100% and 94%, respectively. Given the overall robust results herein, the case is strengthened for the use of miRNAs as a molecular method for body fluid identification.     

The Difficulties in Assessing Wounds Created by .410 Bore Ammunition and Weapons

When interpreting firearm injuries, the distinction between gunshot wounds and shotgun wounds is important, and separation of these categories is typically straightforward. However, .410 bore firearms can make the classification difficult. Shotguns and revolvers that can fire the same .410 bore ammunition are readily available. This study investigates the soot and gunpowder deposits and pellet patterning of these two types of weapons using cartridges specially designed for .410 bore revolvers and standard birdshot pellet ammunition. For both ammunition types, the revolver had more prompt pellet dispersion and positive detection of gunpowder at greater distances compared to the shotgun. Additionally, .410 bore slugs are of similar caliber to many common bullets. In comparing the .410 bore slugs to equivalent bullets, some morphologic differences may be imparted on the skin by the slugs, but the greatest insight into the weapon remained with the retained projectiles.
