Gender Differences in Posttraumatic Stress and Related Symptoms Among Inner-City Minority Youth Exposed to Community Violence

This study examined gender differences in levels of violence exposure, and in levels of posttraumatic stress (PTS) and related symptomatology in a sample of inner-city predominantly African American youth. Because such youth are at risk for exposure to chronic community violence, they are likely to experience considerable distress and clinical or subclinical levels of posttraumatic stress and related symptoms. Previous research has found that although boys are exposed to violence more frequently than are girls, girls are more likely to express posttraumatic stress and related symptoms as a result of violence exposure. Thus, we examined gender as a moderator of the relation between violence exposure and symptoms. A stronger positive association of anxiety and depression symptoms with extent of community violence exposure for girls than boys was found. It was also found that while girls do not appear to differ in their responses to witnessing violence versus being a victim of violence, boys appear to be more distressed by being a victim of violence than by witnessing violence.     

Understanding Contemporary Cryptography and its Wider Impact upon the General Law

As the move toward the wider regulation of cryptography, both within the United Kingdom and elsewhere, becomes increasingly irresistible, the degree of understanding afforded to cryptography at the level of policy formation remains underdeveloped, ambiguous and, at times, misleading. One corollary of such solicitude is that a number of the most important and pervasive legal issues that flow naturally from the widespread availability of cryptography remain largely unexplored. This article attempts to remedy these deficiencies. It begins by offering a brief historical perspective before progressing to consider more substantive issues such as cryptography's aims, power, limitations, effectiveness and future. Ignoring, to a large extent, issues of law enforcement, and focusing, in particular, upon both the law of data protection, and, to a lesser extent, the general law of obligations in the United Kingdom, this article argues that the decision to utilise cryptography will not simply prove a matter of choice, preference or expediency, but of legal and commercial necessity in order to avoid the potential imposition of widespread indeterminate liability.
