The relationships between child physical and sexual abuse and illicit drug use are little understood and underinvestigated.
Data gathered from a study of youths located in two different institutions for detained (Florida) and committed (Colorado)
youthful offenders permitted an examination of this issue. The results indicate the youths' physical and sexual abuse experiences
are significantly and positively related to their use of illicit drugs. The implications of these findings for further research
are drawn. 相似文献
One hundred and fifty-five cord cells were tested for the red blood cell antigens Lua, Lub and Cob in order to collect data on the early postnatal expression of these markers. Additionally, dosage studies were carried out in 8–10-month-old heterozygous children. Antigens Lua and Lub revealed to be significantly less expressed in children of both ages compared with those of their mothers, whereas no such differences could be demonstrated in the expression of the antigen Cob. 相似文献
Among the central tenets of social identity theory are the arguments that individuals’ attitudes and behavior are shaped by (1) perceptions of threat by out-groups toward individuals’ in-group(s) and (2) the strength of individuals’ identification with the in-group perceived to be under threat. In this paper we explore how American identity and Americans’ perceptions of immigrant threat work together to shape their vote choices in the 2016 presidential election. With the presidential campaign of Donald Trump characterized by strong rhetoric that emphasized immigrant threat and American identity themes, we suggest that the effects of immigrant threat perceptions are amplified by individuals’ American identity, with those who have a strong American identity more likely to translate immigrant threat perceptions into support for Trump than those with weaker levels of American identity. Moreover, we consider whether the effects of American identity on vote choice are activated and moderated by individuals’ perceptions of immigrant threat. Using data from the 2016 American National Election Study, we find that the effects of immigrant threat perceptions and American identity on vote choice are magnified by each other: the effects of immigrant threat perceptions are enhanced among individuals with a strong American identity, and the effects of American identity are activated and magnified by perceptions of immigrant threat.
The discussion of “error” has gained momentum in forensic science in the wake of the Daubert guidelines and has intensified with the National Academy of Sciences' Report. Error has many different meanings, and too often, forensic practitioners themselves as well as the courts misunderstand scientific error and statistical error rates, often confusing them with practitioner error (or mistakes). Here, we present an overview of these concepts as they pertain to forensic science applications, discussing the difference between practitioner error (including mistakes), instrument error, statistical error, and method error. We urge forensic practitioners to ensure that potential sources of error and method limitations are understood and clearly communicated and advocate that the legal community be informed regarding the differences between interobserver errors, uncertainty, variation, and mistakes. 相似文献
Terrorism costs money. Although the costs of specific operations may be relatively inexpensive, terrorist organizations require much larger budgets in order to function. But how do terrorist groups acquire funding? What explains the variation in the particular sources used by different groups? This article develops a theory of terrorist financing that identifies criteria by which we can evaluate the different sources of terrorist funding, particularly in terms of their advantages and disadvantages to the terrorist group. These criteria are then applied across a typology of four primary types of terrorist financing: state sponsorship, illegal activity, legal activity, and popular support. 相似文献
Colin Davidson was the British consular official in Japan during and after World War I delegated to run intelligence operations in the country on behalf of the British Indian security authorities. Davidson's original target, Indian revolutionaries based in Japan, soon expanded to include their clandestine links to powerful Japanese political patrons, violating the spirit of the Anglo-Japanese Alliance (1902–23). Davidson's expertise on Japan, combined with intelligence on Japanese ultranationalist support of Indian independence, proved crucial for confirming suspicions about secret Japanese intent against the British Empire, contributing to the decision not to renew the Alliance. 相似文献
Soon after the termination of the Anglo-Japanese Alliance in 1921, Squadron Leader Frederick Joseph Rutland covertly offered the Japanese navy technical help to develop aircraft carriers. In doing so Rutland played a significant role in the evolution of Japan's offensive capability that made the attack on Pearl Harbor possible. Of as lasting importance was the impact the case had in shaping the perception of ‘the Japanese threat’. British security and intelligence agencies' knowledge of Japanese naval intelligence actions in accepting this ‘offer of service’ and running Rutland as a clandestine agent was not balanced by any understanding of the fragmented nature of the Japanese leadership and intelligence bureaucracy. The case in the 1920s provided the Security Service and SIS with the apparent evidence to justify reassessing Japan from benign if opportunistic former ally to hostile power, apparently proving that Japan's intelligence actions reflected sustained hostile intent throughout the inter-War period. 相似文献
Abstract The common wisdom is that assisted housing developments have both a direct and an indirect impact on concentrated poverty. The indirect effects are based on the notion that the negative stereotypes associated with such developments spill over into the surrounding neighborhoods, causing people who can leave to do so or avoid the neighborhood and leaving behind only the more disadvantaged segments of society. An increase in concentrated poverty in the neighborhood surrounding the development results. Prior studies, relying on aggregated data, are consistent with this thesis. The overwhelming majority of the statistical models in my study, however, found these relationships to be spurious. Once individual and macrolevel characteristics were controlled for, the relationships disappeared. These findings imply that assisted housing developments will not typically contribute to concentration of poverty in surrounding neighborhoods and suggest that much of the negative reaction to assisted housing developments is unwarranted. 相似文献
