This article examines the traditional political and economic factors that have been purported to explain the prevalence of insurgency. It tests the following hypotheses at the subnational level in Colombia: guerrilla violence is positively associated with exports; higher levels of insurgency are associated with low levels of GDP per capita or negative growth rates; guerrilla violence emerges in the context of weak state presence; and higher levels of state repression are associated with higher levels of insurgent violence. The analysis utilizes a zero-inflated negative binomial to capture dynamics of both intensity and onset of violence. The econometric analysis is supplemented with cartographic visualization and qualitative analysis. 相似文献

AbstractOut-of-home (OOH) advertising media have expanded worldwide and the shape and format of these media globally, as well as in South Africa, have changed considerably. Until recently, the OOH advertising media landscape consisted primarily of outdoor advertising or billboards reaching vehicular traffic, but now has expanded to include a wide range of OOH advertising media types which aim to reach a mobile audience wherever they live, work, play, drive, shop or commute. Currently there is no coherent contemporary framework to compare and select the most effective media options to reach a selected target market in a specific OOH audience environment. This article draws from academic and practitioner sources to propose a classification framework for OOH advertising media in South Africa comprising four major platforms: outdoor advertising, transit media advertising, street-and-retail furniture advertising, and digital and ambient OOH media channels. The framework serves to inform marketers of viable and cost-effective traditional and contemporary OOH advertising media options. It also indicates what platforms are appropriate to reach specific audiences effectively in a variety of environments outside their homes. This is the first framework of its kind for the South African context that offers an orderly, integrated basis for future research. 相似文献

This article considers the conduct of armed parties in the invasion of Panama on 20 December 1989 by United States forces, in relation to the standards established by the international laws of war and the Geneva Conventions of 1949. The article confines itself to the conduct of US and Panamanian armed forces from the commencement of hostilities, and does not consider arguments for or against the invasion itself. The authors, on behalf of the US‐based Americas Watch, a human rights monitoring organization, visited Panama in January 1990, and collected information contained in the article. The article concludes that US forces failed in their Geneva Convention obligations with respect to the detentions of Panamanian POWs and civilians. It also concludes that US forces failed to exercise precautions to minimize collateral civilian casualties in the attack on the Panamanian military headquarters. It finds that Panamanian forces put non‐combatant civilians at risk by dressing in civilian clothes and firing from civilian‐occupied structures. It estimates the number of Panamanian civilian dead at approximately 300. The article further considers protection of human rights under the new Endara government, and the plight of refugees left homeless by the invasion. 相似文献

This paper uses an analytical framework derived from Pierre Bourdieu's sociology to explain the genesis of the European Security and Defense Policy (ESDP). Long-term social and institutional processes at work in the making of ESDP are addressed through an emphasis on the institutionalization of social fields, the impact of structural crises, and the socialization of policy makers into specific schemes of perception and action (habitus). Two arguments follow from this framework. First, the paper shows that the creation of ESDP after 1998 would have been impossible without the prior institutionalization of two transgovernmental arenas: (1) the European foreign policy field, wherein EU diplomats vie for influence over EU policies; and (2) the international defense field, centered upon military relations within NATO. Second, ESDP results from the strategies of a number of diplomats and military leaders who, following the end of the Cold War, perceived that they faced important organizational crises in their respective fields. This sociological framework provides a more nuanced account of ESDP's creation than that proposed by the two dominant explanations in international relations theory—realism's balancing and constructivism's strategic culture convergence. Combining structural and ideational factors, it elucidates three empirical puzzles: the lack of opposition to ESDP when it was launched, the motives of policy makers who proposed ESDP, and the disappearance of alternative options for the European security architecture. 相似文献

Abstract The NRF and the EU BG were launched to enable NATO and the EU respectively to shed some of their Cold War roles and begin to incorporate new organisational functions as means to meet their members’ needs in a changing global security environment. However, since their launch the two rapid reaction forces have both failed to fully consolidate. Our argument is that an examination of intra-NATO/EU contested identities at three levels (supra-state, state and sub-state) provides us with additional insights for the lack of success in consolidating the two sets of rapid reaction forces. 相似文献

The history of the International Conference on Penal Abolition (ICOPA) is explored, assessing major trends shaping the current growth of carceral practices and offering suggestions for the future of the conference movement. The goal here is to facilitate the expansion of abolitionism by describing the changing nature of what is to be abolished. A discussion of the emergence of prison abolitionism and of the ICOPA is presented, describing the shift in focus from prison to penal abolition. Taking these developments and character into account, an abolitionist gaze must be expanded to reflect a carceral abolition project, encompassing contemporary penal abolitionism while acknowledging the proliferation of carceral practices and spaces outside the traditional penal system. 相似文献

The quality and the quantity of information recalled by eyewitnesses during a criminal investigation is of crucial importance. To increase the volume of details recalled during an interview, the cognitive interview recommends using various retrieval strategies to enhance recall. We tested a new retrieval instruction, the open depth (OD) instruction. The efficacy of this new instruction was assessed with the number of unit of information and the accuracy rate. We also assessed the cost-and-benefit of this new instruction with measures of repetition. Students watched a video of a simulated robbery and participated later in face-to-face interviews. In Study 1 (N=60), the cognitive interview using the OD instruction increased recall compared to the interview using the change of perspective (CP) instruction, without affecting the accuracy rate. The redundancy rate was higher with the OD instruction than with the CP instruction. In Study 2 (N=40), the OD instruction generated more new information without affecting the accuracy rate than the interview using motivated recall (MR) instruction. The repeated information to new information ratio was lower with the OD instruction than with the MR instruction. The advantages of the OD instruction for investigative interviewing purposes are discussed. 相似文献

In 1746, Antoine Deparcieux (1703–1768) published Essai sur les probabilités de la durée de la vie humaine [An Essay on the Probabilities of the Duration of Human Life]. Deparcieux analyzed in detail empirical observations. As a mathematician and physicist, he can be considered, after Halley and Struyck, one of the founders of the estimation of longevity and all the issues surrounding that concept. The article analyzes the statistical data Deparcieux presented in his book and examines the way he dealt with them. He criticized the methods of his predecessors and showed what, according to him, were “good” data. Although he only had lists of annuitants or ecclesiastical registers at his disposal and no data from the government or state, Deparcieux constructed his calculations with careful regard to the value and quality of the figures used. He also envisaged a specific project to collect data about infant mortality. His work holds an important place in the history of French demographic statistics. 相似文献

In recent years, scopolamine has become a drug of common use for recreational and predatory purposes and several ways of administration have been devised. A method for the rapid analysis of suspicious samples was developed, using a portable capillary electrophoresis with contactless conductivity detection. The method allows the separation of scopolamine from atropine which has a similar structure and is present along with scopolamine in some samples. The method was demonstrated to be useful for the fast analysis of several types of evidential items which have recently been reported to have been abused with fatal consequences or employed for criminal purposes. An infusion of Datura stramonium L., in which scopolamine and atropine naturally coexist, was analyzed for being frequently consumed for recreational purposes. A spiked moisturizing cream and six spiked alcoholic beverages were also analyzed. In spite of the complexity of the specimens, the sample pre-treatment methods developed were simple and fast. 相似文献
