Studies of crime hot spots have argued that landlords’ management styles, specifically their tenant screening and property monitoring techniques, affect crime. These studies, however, have rarely considered the political–economic contexts in which these actions take place: specifically, how landlords’ behaviors are shaped by, and themselves reproduce, larger rental market structures. Drawing on data pertaining to eviction rates, criminal incidents, housing code violations, and landlord behavior in Milwaukee, Wisconsin, this study documents how extractive rental management strategies, such as weak tenant screening, frequent eviction filings, and property disinvestment, concentrate crime at particular properties. In turn, high rates of crime in a neighborhood incentivize these extractive landlord strategies. By showing how landlords’ economic strategies are central to urban crime geographies, this study contributes to our understanding of third-party policing by revealing the limits of market-based solutions to place management dilemmas.  相似文献

This article assesses the prospects for a clearly articulated economic diplomacy approach in South Africa's foreign policy. It argues that while South Africa's foreign policy has been to a considerable extent normatively grounded, it has failed to develop a coherent economic diplomacy that is based on focused and distinctly expressed priorities. This is a crucial gap that limits the country's ability to respond to regional and global changes, in particular those posed by emerging powers. The article identifies a number of gaps in South Africa's foreign policy approach and highlights its oblivion to global developments and geopolitical dynamics in the African continent. It sets out possible policy outlines for developing a clearer and stronger economic diplomacy. The building blocks for such an approach include the identification of strategic foreign policy priorities; greater institutional co-operation among agencies dealing with economic and foreign policy development; synergies between corporate strategies and government's foreign policy objectives; and the need for South Africa to develop a stronger leadership ambition in the African continent, both to contribute to Africa's development and to pursue its own economic interests. This ambition will require awareness of South Africa's own limitations, thus focusing the better part of its foreign policy on a limited set of countries that match strategic priorities.  相似文献

This articale argues that agency, the normative theory associated with the “acting for” relationship in society, has had a profound, but often unrecognized affect on ethics in public administration. Accordingly, it seeks to provide a brief review of agency theory as it applies to contemporary American public adminis- tration. The review provides an overview of agency theory, gives an example of how deeply it influences American public administration, shows how it facilitates ethical action in administration and reviews some of the major obstacles to employing agency theory in the modern American administrative state.  相似文献

This article revisits the debate, hosted by this journal in the 1990s, on whether the Provisional IRA campaign was sectarian. In the light of current debates about how Northern Ireland deals with its past, it challenges the analysis that emphasises the non-sectarian ideology of republicanism and ignores the effects of IRA violence. It uses research on the IRA campaign in Fermanagh and south Tyrone to argue that the campaign was unavoidably sectarian but rejects current attempts to label it a form of “ethnic cleansing.”  相似文献

Abstract

Explanations of the growing importance of risk to regulation identify three processes; the need to respond to newly created and discovered risks; the growth of regulatory frameworks; and the use of the risk instrument as an organizing idea for decision-making in modernity. Synthesizing these explanations, we propose a theory of risk colonization. We introduce a distinction between societal and institutional risks, the former referring to threats to members of society and their environment, and the latter referring to threats to regulatory organizations and/or the legitimacy of rules and methods of regulation. We argue that pressures towards greater coherence, transparency, and accountability of the regulation of societal risks can create institutional risks by exposing the inevitable limitations of regulation. In the first stage of risk colonization, framing the objects of regulation as ‘risks’ serves as a useful instrument for reflexively managing the associated institutional threats. This can be followed, in a second stage, by a dynamic tension between the management of societal and institutional risks that results in spiralling feedback loops. The very process of regulating societal risks gives rise to institutional risks, the management of which sensitizes regulators to take account of societal risks in different ways. We discuss links between this theory and the concept of governmentality and conclude with some speculations about the possible positive and negative consequences of risk colonization.  相似文献

In sub-Saharan Africa, 72 per cent of urban and 98 per cent of rural households use fuelwood for energy. In Kenya use of charcoal in urban areas has risen by 64 per cent in two decades. Despite the charcoal industry providing employment to 500,000 people and generating over US$427 million that benefits grassroots communities, it has been kept out of the formal economies of this country. This review presents the status of the charcoal industry in Kenya, highlighting its contribution to livelihoods, production, utilisation, and implications for the environment; policy issues; and stakeholders' involvement. The review also proposes strategies to improve the sustainability of this sector.

La production de charbon de bois au Kenya et des stratégies pour l'augmentation de sa durabilité

Dans l'Afrique subsaharienne 72 pour cent de ménages urbains et 98 pour cent de ménages ruraux se servent du bois combustible pour leur propre énergie. Au Kenya l'usage de charbon de bois dans les secteurs urbains a augmenté par 64 pour cent au cours de deux décennies. Malgré le fait qu'elle fournit un emploi à 500,000 personnes et qu'elle génère plus de US$427 million de bénéfice aux collectivités populaires, l'industrie du charbon de bois reste écartée des économies formelles de ce pays. Cet examen présente la situation de l'industrie du charbon de bois au Kenya, en soulignant sa contribution aux moyens d'existence, à la production, et à l'utilisation ainsi que les implications pour l'environnement ; des questions concernant la politique ; et l'implication des parties prenantes. L'examen propose également des stratégies pour l'amélioration de la durabilité de cette industrie.

Producción de carbón y estrategias para aumentar su sostenibilidad en Kenia

En el África subsahariana, 72% de los hogares urbanos y 98% de los hogares rurales utilizan la leña como fuente de energía. En las áreas urbanas de Kenia, el uso de carbón ha aumentado 64% en dos décadas. A pesar de que la industria de carbón crea empleo para 500 mil personas, generando us$427 millones en beneficios para las comunidades de base, se la ha marginado de las economías formales de este país. El presente artículo examina la situación de la industria de carbón en Kenia, analizando, por un lado, su contribución a los medios de vida, y por otro, su forma de producción y su utilización, así como sus implicaciones para temas de política ambiental, además de la participación de los actores en la misma. Asimismo, el artículo propone estrategias para mejorar la sostenibilidad del sector.

Produção de carvão e estratégia para aumentar sua sustentabilidade no Quênia

Na África Subsaariana, 72 por cento de famílias da zona urbana e 98 por cento de famílias da zona rural utilizam lenha como fonte de energia. No Quênia,o uso de carvão nas áreas urbanas cresceu 64 por cento em duas décadas. Apesar da indústria de carvão proporcionar emprego a 500.000 pessoas e gerar mais de US$427 milhões que beneficiam comunidades de base, ela tem sido deixada de fora das economias formais deste país. Esta revisão apresenta o status da indústria de carvão no Quênia, destacando sua contribuição para os meios de subsistência, produção, utilização e implicações para o meio ambiente; questões de políticas e envolvimento dos stakeholders. A revisão também propõe estratégias para melhorar a sustentabilidade deste setor.  相似文献

Abstract

The purpose of the current study was to examine the effect of clothed and unclothed human figure drawings (HFDs) on children's reports of touch. Eighty 4/5-year-olds and 80 9/10-year-olds participated in a staged event in which measurements of their body parts (e.g. waistline) were taken. Specifically, they were touched on 10 different locations. Immediately or three weeks after the event, they had to report where they had been touched. Half of the children received a clothed HFD while the other half was provided with an unclothed HFD to assist children in their recall. When we compared children's recall before and after the presentation of a HFD, we found that clothed and unclothed HFDs significantly decreased the accuracy of children's reports of touch. So, although children reported more correct touches after the presentation of a HFD, they were also more likely to include more incorrect information in their reports of touch.  相似文献

Abstract

Mentors and school heads play cardinal roles in teacher education programmes in most countries, including Zimbabwe. The side-effects of such symbiosis have not yet been investigated fully. This article used a qualitative methodological approach to investigate the perceptions of some Zimbabwean student teachers regarding their teaching practice experiences. A sample of 10 ex-teaching practice students from a teacher education college was selected and interviewed during data collection using a semi-structured interview schedule. The participants reported a high prevalence of sexual harassment/aggression of the students by the host schools' heads and mentors, irrespective of student gender. The form of aggression included seeking sexual favours and intimidation. Most perpetrators used metaphors and satirical or sarcastic language to convey their intentions. The female student teachers reported higher incidences than did the male students. Constant workshopping is imperative to remind mentors and school heads of their professional and social obligations regarding teacher education.  相似文献

Patients who suffer from Crohn's disease are prone not only to the complications of a relapsing, unpredictable disease, but also to feelings of stigmatization; depression; and increased risk of suicidal ideation, suicide, or drug and alcohol abuse. Cases performed at the Jackson County Medical Examiner's Office from 2008 to 2010 were reviewed. Autopsy findings, investigator reports, toxicology results, medical records, and interviews with survivors were analyzed. Twelve cases of Crohn's disease were recovered. In 10 of these cases, inflammatory bowel disease was not the cause of death. Instead, psychosocial consequences of the disease had significant implications in the deaths. The mean age of decedents was 45 years, with a female predominance. In eight cases, the decedents lived alone. Five patients had issues of acute or chronic drug or alcohol use. Five patients committed suicide. These cases underscore the role of psychosocial factors that can contribute significantly to the cause of death in patients with Crohn's disease.  相似文献

Given the relatively new phenomenon of online child exploitation – an important area of criminological and policy concern – it is difficult to obtain long term trend data on reported convictions. Existing legislative and prosecution-based approaches, while important, are unlikely to be adequate. This analysis of the legislative and prosecution-based responses in five Commonwealth countries (Australia, Canada, New Zealand, South Africa and United Kingdom), highlights the need for clear national and international definitions as the lack of consistency in the international legislative environment creates opportunities for sexual exploitation of children. To provide a multi-faceted and non-prosecutorial approach to address online child exploitation including the commercial exploitation of children, this paper identifies five potential research questions.  相似文献
