The aim of this article is to analyze the tactical behavior of Somali pirates, international naval forces, and the shipping community operating in the Gulf of Aden and the Somali Basin. To what extent has tactical behavior changed over time and can this process be understood in more theoretical terms? Our theoretical framework centers around some concepts often used in naval doctrine, discussing tactical change in terms of command and control, force, mobility, protection, intelligence, and endurance. We also evaluate this change using two tactical concepts—tactical adaptation and tactical development. The empirical data is based on statistics from the International Criminal Court-International Maritime Bureau and the EU NAVFOR Operation Atalanta, as well as interviews. We conclude that Somali piracy has unquestionably adapted their tactics to circumstances, while naval forces have increased their capacity to capture pirates and shipping to avoid pirates.  相似文献

Adermatoglyphia is a very rare autosomal‐dominant condition that is genetically inherited and causes an individual to be born without conventional ridge detail on either their palmar or plantar surfaces (the fingers and palms of the hands and the toes and the soles of the feet). While adermatoglyphia has been the focus of medical and genetic research, no previous research has been conducted with regard to the forensic recovery and identification of marks from an adermatoglyphic individual. By observation of ridge detail donated by an adermatoglyphic subject, the study uses different methods in order to capture fingermarks (methods include: inked capture, livescan (biometric) capture, cyanoacrylate fuming, ninhydrin enhancement, and physical developer). Unusually, the purpose of this paper ends up presenting a number of examples of an absence of evidence; unsuccessful attempts made to capture and enhance fingerprint ridge detail. This is determined over a range of standard means including "live" donations by the adermatoglyphic subject onto the Livescan system, and enhancements of latent donations. The subject shows to leave either insubstantial fingermarks with no detail, or no mark whatsoever.  相似文献

This paper considers transformations in the concept of national identity post‐unification. In particular, it is interested in examining the changed status of the NS past in contemporary formulations of national identity. Whilst during the Historikerstreit conservative thinkers predicated the plea for conventional patriotism upon a ‘normalisation’ or ‘reladvisation’ of the NS past, left‐liberal discourse based the case for a post‐national Verfassungspatriotismus upon the critical engagement with the NS period. The collapse of the Cold War political framework has profoundly altered the polarised discourse over the German past and during the 1990s the critical consciousness of National Socialism became a central tenet of contemporary formulations of national identity. The paper attempts to place the contemporary discourse on national identity within a broader historical context and to consider reasons for recent transformations in perceptions of the German national past.  相似文献

Purpose. The Not‐Real‐People picture set serves as stimulus material for assessing paedophilic sexual interest. The pictures were generated according to five stages of sexual maturation from infancy to adulthood. While experts seem to be able to discern between the pictures based on maturity levels for a nude variant of the stimuli, it remained unclear whether lay persons would be able to reliably distinguish between picture of clothed individuals from various maturity levels. Methods. Heterosexual university students (52 females, 50 males) participated in a paired comparison task, deciding which of the persons shown on two pictures was younger and which one was more attractive. Additionally, reaction times were recorded. Results. Both male and female judges were able to differentiate between stimuli from the opposite sex with regard to age: the perception of the stages of pubertal development conformed to a measurement on a ratio scale. Similarly, the decisions on attractiveness of the categories were in accordance with a ratio scale. Male participants favoured adolescent and adult female stimuli. Contrary to expectation, female participants did not show a preference for any single age category. Conclusions. The stimuli appear suitable for diagnostic purposes. The participants' decisions reflect the inherent maturity levels of the persons depicted. Reaction times in the paired comparison paradigm increase with task difficulty (i.e., similitude of pictures). The implications for indirect measures of sexual interest, based on reaction times, are discussed.  相似文献

The prevalence of sexual violence is increasingly being studied in India. Yet the determinants of sexual violence, irrespective of physical violence, remain largely unexplored. Here the authors identify the determinants of sexual violence, and additionally, explore how the presence of physical violence modifies these determinants. A cross-sectional analysis is conducted using baseline data from a longitudinal study involving young married women attending reproductive health clinics in Southern India. A multivariable logistic regression analysis is conducted to first identify determinants of sexual violence and then repeated after stratifying elements based on presence or absence of physical violence identified from participants' reports. 36% and 50% of the participants report experiencing sexual and physical violence, respectively. After adjusting for other covariates, women's partners' characteristics are found most significantly associated with their odds of experiencing sexual violence. These characteristics include husbands' primary education, employment as drivers, alcohol consumption, and having multiple sex partners. Women's contribution to household income also increases their odds of experiencing sexual violence by almost twofold; however, if they are solely responsible for "all" household income, the relationship is found to be protective. Physical violence modifies the determinants of sexual violence, and among women not experiencing physical violence, husbands' primary education and employment as drivers increase women's odds of experiencing sexual violence nearly threefold, and women who contribute "all" the household income (n = 62) do not experience sexual violence. These relationships are not significant among women experiencing physical violence. Study findings improve the understanding of the determinants of sexual violence. Future research is needed to examine the risk factors for different types of GBV independently and to tease apart the differences in risk factors depending on women's experiences. The significance of male partners' characteristics warrants in-depth research, and in order to promote gender-equitable norms, future interventions need to focus on male behaviors and men's day-to-day survival challenges, all of which likely influence conflicts in marital relationships.  相似文献
