This qualitative study of drawings created by inner‐city, Latino, junior high school students examines how these drawings are made, how they are used, and how they are read by other Latinos as visual texts that encode and communicate culturally important information. The study is based on interviews with young Latino adults about the roles these drawings played during their adolescence. The interviews revealed that these drawings function as texts in a system of visual communication. They also illustrate how such drawings can be linked to cultural identities, and how their power derives not just from the imagery they include but from how they are used to shape and support social interaction.  相似文献

We analyze the risk of severe fatal accidents causing five or more fatalities and for nine different activities covering the entire oil chain. Included are exploration and extraction, transport by different modes, refining and final end use in power plants, heating or gas stations. The risks are quantified separately for OECD and non‐OECD countries and trends are calculated. Risk is analyzed by employing a Bayesian hierarchical model yielding analytical functions for both frequency (Poisson) and severity distributions (Generalized Pareto) as well as frequency trends. This approach addresses a key problem in risk estimation—namely the scarcity of data resulting in high uncertainties in particular for the risk of extreme events, where the risk is extrapolated beyond the historically most severe accidents. Bayesian data analysis allows the pooling of information from different data sets covering, for example, the different stages of the energy chains or different modes of transportation. In addition, it also inherently delivers a measure of uncertainty. This approach provides a framework, which comprehensively covers risk throughout the oil chain, allowing the allocation of risk in sustainability assessments. It also permits the progressive addition of new data to refine the risk estimates. Frequency, severity, and trends show substantial differences between the activities, emphasizing the need for detailed risk analysis.  相似文献

The study of the terms and mode of application of African customary law in South Africa has generally been neglected both by lawyers and African Studies scholars. In the case of lawyers, there is little interest in a law potentially relevant to seventy per cent of the population ‐ where that seventy per cent is for the most part unable to pay lawyers’ fees (Suttner, 1974a: 189).

In the case of students of African studies, the segregated legal and judicial system may seem of marginal consequence, in the light of the more serious disabilities that people experience through more patently repressive laws, such as those regulating influx control, resettlement, banishment and so forth, let alone laws concerning directly political activities. It would nevertheless be wrong, I shall try to show, to dismiss this area as unimportant or innocuous.

This paper seeks to demonstrate how the special court and legal system set up to deal with civil cases between Africans, contributes ideologically, economically and socially’, to the national oppression of the African people.  相似文献

Strategy development in today's volatile business environment demands increased management concern with fundamental issues which go beyond the balance sheet and the income statement to deal with the proper positioning of the corporation and its units to achieve long-term profitable survival. This is well understood. On the other hand, it is equally clear that management capacity—in terms of man hours of talent available—is the most important resource of any corporation and is also limited. In this article the authors set out to develop a frame of reference for analysing the corporation, its individual business and its competitors. Their objective is to provide management with the tools they need to deploy their creative entrepreneurial talent more efficiently by focusing on strategically relevant issues, using guidelines based on the ever-increasing body of research available today.  相似文献

The aim of this paper is to give a brief overview of the historical and current understanding of and care for children with learning difficulties who displayed challenging behaviour in the United Kingdom. It is clear that challenging behaviour is not a new phenomenon but has existed throughout the history of learning difficulty.  相似文献

Based on research showing that alcohol expectancy and gender both play a role in sexual perceptions, we factorially crossed the apparent drinking status of yoked pairs consisting of a participant and a target person (a confederate posing as co‐participant). Alcohol expectancy interacted with gender in complex ways to influence sexual perceptions. We also found behavioral effects: men showed more erotic material to both male and female targets than women did. Men perceived the target as more sexually aroused by erotic material than women did. Men also showed more erotic material to drinking targets than to non‐drinking targets. Sexual perceptions and erotica‐showing behavior were correlated significantly and positively. We discuss these findings in terms of implications for postdrinking heterosexual encounters.  相似文献

Drawing on Charles Tilly’s work on inequality, democracy and cities, we explore the local level dynamics of democratization across urban settings in India, South Africa, and Brazil. In all three cases, democratic institutions are consolidated, but there is tremendous variation in the quality of the democratic relationship between cities and their citizens. We follow Tilly’s focus on citizenship as the key element in democratization and argue that explaining variance across our three cases calls for analyzing patterns of inequality through the kind of relational lens used by Tilly and recognizing that patterns of contestation are shaped by shifting political relationships between the nation and the city. We conclude that Tilly’s theoretical frame is nicely sustained by the comparative analysis of cases very different from those that stimulated his original formulations.  相似文献
