An assessment of human performance in stabbing.

Stab-resistant body armour is now becoming a standard item of equipment for police officers in the United Kingdom. In the UK these are usually required to have a stab resistance as specified by the Police Scientific Development Branch KR42 standard [G. Parker, PSDB Stab Resistant Body Armour Test Procedure, Police Scientific Development Branch, Publication No 10/93, 1993]. There are several other test standards, all of which specify that body armour must resist penetration by a specific blade type delivered at a specific energy level or range of levels. However, the actual range of energy levels specified varies over almost an order of magnitude and the basis for these levels is not clearly defined. This paper describes tests to determine the energy range and characteristics of stabbing actions that might be directed against stab resistant body armour by an assailant. The energy and velocity that can be achieved in stabbing actions has been determined for a number of sample populations. Volunteers were asked to stab a target using an instrumented knife that measured the axial force and acceleration during the stabbing. The maximum energy obtained in underarm stabbing actions was 64 J whilst overarm stabbing actions could produce 115 J. The loads produced on contact with the target often approached 1000 N.     

Islamization in Malaysia: processes and dynamics

Over the past three decades Malaysian society has undergone radical change and transformation. On one level this has been brought about by the country's rapid economic transformation, but equally significant has been the deepening Islamization of the country. From banking to law, from dress to education policy, almost no sector of Malaysian society has escaped the growing influence of Islam upon the socioeconomic and political make-up of the country. The prevalent explanation for this dynamic has been the political competition between the United Malay National Organization and the Islamic opposition party, Parti Islam Se-Malaysia, since the early 1980s. Such explanations, however, clearly marginalize the role of other societal factors and dynamics. Consequently, this article contends Islamization in Malaysia has created a series of processes that have produced results which are self-reinforcing. Ironically, the strategy for diverting the extremes of Islamic revival by co-option has actually produced a far more dynamic penetration of state and society by conservative Muslims who have become a powerful constituency supportive of the further religious coloration of government bureaucracies and programmes.

Lesbian and Gay Immigrants' Post-Migration Experiences: An Integrative Literature Review

This integrative literature review synthesizes recent empirical knowledge about lesbian and gay immigrants' post-migration experiences. Twenty-four studies with various designs are included. The literature shows that those immigrants encounter some opportunities but also many challenges on economical, social and identity levels, thus soliciting coping strategies. Results are synthesized under five topics: the delicate situation in which they find themselves for revealing their lesbian or gay sexual orientation; the racist and homophobic discrimination they can experience; their renegotiation of socioeconomic status; the identity and affiliation challenges they have to overcome; and the hardships that can impact their health.     

Artificial Intelligence,Forward‐Looking Governance and the Future of Security

Over the last years, AI applications have come to play a role in many security‐related fields. In this paper, we show that scholars who want to study AI’s link to power and security should widen their perspective to include conceptual approaches from science and technology studies (STS). This way, scholars can pay attention to critical dynamics, processes, practices, and non‐traditional actors in AI politics and governance. We introduce two STS‐inspired concepts – the micro‐politics of design and development and co‐production – and show how the study of AI and security could benefit from them. In the final section, we turn to the study of AI in the context of Switzerland to underscore what aspects the two previously introduced concepts help to highlight that remain invisible for traditional approaches.     

Supportive Community Resources Are Associated with Lower Risk of Substance Use among Lesbian,Gay, Bisexual,and Questioning Adolescents in Minnesota

Gas chromatographic detection of cocaine and cocaethylene in hair of mice chronically injected with cocaine or cocaethylene and fed ethanol.

GC and GC/MS analysis was used to detect cocaine and cocaethylene in hair extracts of mice injected with 20 mg/kg cocaine hydrochloride or an equivalent dose of cocaethylene fumarate twice daily for 3 weeks. Some mice were fed liquid Lieber-DeCarli diets containing ethanol (26% of total calories) and injected twice daily with the same doses of cocaine or cocaethylene or combination of cocaine and morphine (5 mg/kg). The average concentrations of cocaine in different experimental groups were in the range of 0.9-2.4 ng/mg of hair and for cocaethylene, 2.4-2.8 ng/mg of hair. There were no significant differences in hair concentrations of cocaine among groups receiving cocaine treatment, nor were there significant difference in cocaethylene concentration in hair in the two groups administered cocaethylene. In hair extracts of mice treated with cocaine and ethanol, levels of cocaethylene were below the limit of detection.     

Urbanization processes and policies in Africa: lessons from Kenya,Tanzania, Zambia and Zimbabwe

The urbanization experiences of Kenya, Tanzania, Zambia, and Zimbabwe are examined, with emphasis on the effectiveness of policies designed to influence urbanization. The first part of the study describes the measures adopted; the second part attempts to evaluate their effectiveness as well as their impact on poverty and inequality.
