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

Cathinone derivatives (bath salts) have emerged as the latest drugs of abuse. 3,4‐methylenedioxypyrovalerone (MDPV) is the primary active ingredient in bath salts used in this country. This article presents the second reported cause of death by MDPV intoxication alone. In April 2011, a delusional man was emergently brought to a hospital, where he self‐reported bath salt usage. He became agitated, developed ventricular tachycardia, hyperthermia, and died. Comprehensive alcohol and drug testing was performed. Using the alkaline drug screen, heart blood contained 0.7 mg/L MDPV and peripheral blood contained 1.0 mg/L MDPV. His bizarre behavior with life‐threatening hyperthermia was consistent with an MDPV‐induced excited delirium state. MDPV is not yet found by routine immunoassay toxicology screens. Testing for MDPV should be considered in cases with a history of polysubstance abuse with stimulant type drugs, report of acute onset of psychogenic symptoms, excited delirium syndrome, or presentation in a hyperthermic state.  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

Most contemporary analysts explain ethnic identity as a socially rooted phenomenon which can be catalyzed by changes in both economic and political conditions. Taking the 1982 debt crisis as a main triggering event, this article analyzes the relationship between economic adjustment and increasing levels of indigenous mobilization in Latin America. Through a comparison of the Bolivian, Peruvian, and Mexican cases,the analysis reveals wide variation in the types and levels of ethnic conflict in the region. Explanations for these differences center on the timing and content of economic adjustment policies, and on the institutional opportunities available for expressing and channeling economic and political demands. The article concludes that political and economic liberalization are likely to clash when shrinking the state also removes channels for popular participation; moreover, when those that bear most of the adjustment burden are also challengers to national identity, states ignore this challenge at their peril. Alison Brysk is assistant professor of politics at the University of California at Irvine. Her book,The Politics of Human Rights in Argentina, was published by Stanford University Press. Various aspects of her current research on Latin American indigenous rights movements have appeared inComparative Political Studies, Latin American Perspectives, andPolity. Carol Wise is assistant professor of political science at Johns Hopkins University's School of Advanced International Studies. She has published articles on Latin American political economy inInternational Organization, Latin American Research Review, and theJournal of Latin American Studies; she is the editor of a forthcoming collection entitledThe Post-NAFTA Political Economy: Mexico and the Western Hemisphere.  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

This article investigates the recent so-called Spanish Revolution of 2011 with a view to understanding what it reveals about the current relationship between protest and electoral modes of participation. Theories of “disaffeccted radicalism” that grew up following the 1960s period of civil unrest strongly advocated the view that protest activity boosted electoral abstention. More recent work on protest, however, has pointed to its “normalization” and linkage to more conventional modes of participation. The Spanish case of 15M constitutes a useful new test of the two theories given that it mixed an explicit rejection of the choices voters faced with a criticism of political apathy. I examine the validity of each argument using a four-wave online panel survey and fixed-effects model to unravel how engagement in the 15M protest activity affected Spaniards' attitudes towards voting. The results provide fresh support for the normalization argument about a convergence of electoral and non-electoral types of activity. What is more, protest here seems to have a socialization effect that leads people to look at elections in a more positive manner.  相似文献

The study examined whether and how characteristics of childhood sexual abuse and disclosure influenced three dimensions of psychosexual functioning—emotional, behavioral and evaluative—during adulthood. The sample included 165 adults who were sexually abused as children. The General Estimating Equation was used to test the relationship among the predictors, moderators and five binary outcomes: fear of sex and guilt during sex (emotional dimension), problems with touch and problems with sexual arousal (behavioral), and sexual satisfaction (evaluative). Respondents who were older when they were first abused, injured, had more than one abuser, said the abuse was incest, and told someone about the abuse were more likely to experience problems in at least one area of psychosexual functioning. Older children who told were more likely than younger children who told to fear sex and have problems with touch during adulthood. Researchers and practitioners should consider examining multiple dimensions of psychosexual functioning and potential moderators, such as response to disclosure.  相似文献
