The debate over land law reform in Africa has been framed asa referendum on the market – that is, as a debate pittingadvocates of the growth-promoting individualization of propertyrights against those who call for protecting the livelihoodsand subsistence rights of small farmers. This article arguesthat the prospect of land law reform also raises a complex bundleof constitutional issues. In many African countries, debatesover land law reform are turning into referenda on the natureof citizenship, political authority, and the future of the liberalnation state itself. The article describes alternative landreform scenarios that are currently under debate, and identifiesthe constitutional implications of each. The practical salienceof the issues is illustrated through reference to land reformpolitics in Côte d’Ivoire, Uganda, South Africa,and Tanzania.  相似文献

This article explores the role of maps in the construction and development of ethnographic taxonomies in the mid-century Russian Empire. A close reading of two ethnographic maps of “European Russia” produced by members of the Imperial Russian Geographical Society, Petr Keppen (1851) and Aleksander Rittikh (1875), is used to shine a spotlight on the cartographical methods and techniques (lines, shading, color, hatching, legends, text, etc.) employed to depict, construct, and communicate these taxonomies. In doing so, this article draws our attention to how maps impacted visual and spatial thinking about the categories of ethnicity and nationality, and their application to specific contexts and political purposes within the Empire. Through an examination of Keppen’s and Rittikh’s maps, this article addresses the broader question of why cartography came to be regarded as such a powerful medium through which to communicate and consolidate particular visions of an ethnographic landscape.  相似文献

Attachment, affect, and sex shape responsivity to psychosocial stress. Concurrent social contexts influence cortisol secretion, a stress hormone and biological marker of hypothalamic–pituitary–adrenal axis activity. Patterns of attachment, emotion status, and sex were hypothesized to relate to bifurcated, that is, accentuated and attenuated, cortisol reactivity. The theoretical framework for this study posits that multiple individual differences mediate a cortisol stress response. The effects of two psychosocial stress interventions, a modified Trier Social Stress Test for Teens and the Frustration Social Stressor for Adolescents were developed and investigated with early adolescents. Both of these protocols induced a significant stress reaction and evoked predicted bifurcation in cortisol responses; an increase or decrease from baseline to reactivity. In Study I, 120 predominantly middle-class, Euro-Canadian early adolescents with a mean age of 13.43 years were studied. The girls’ attenuated cortisol reactivity to the public performance stressor related significantly to their self-reported lower maternal-attachment and higher trait-anger. In Study II, a community sample of 146 predominantly Euro-Canadian middle-class youth, with an average age of 14.5 years participated. Their self-reports of higher trait-anger and trait-anxiety, and lower parental attachment by both sexes related differentially to accentuated and attenuated cortisol reactivity to the frustration stressor. Thus, attachment, affect, sex, and the stressor contextual factors were associated with the adrenal-cortical responses of these adolescents through complex interactions. Further studies of individual differences in physiological responses to stress are called for in order to clarify the identities of concurrent protective and risk factors in the psychosocial stress and physiological stress responses of early adolescents.  相似文献

Abstract

This paper uses the World Values Survey to investigate the determinants of perceived social status in India. Caste is still the largest determinant, yet not the only one, as income, education and occupation are all relevant factors. However, only unlikely improvements in those economic attributes could offset the burden of being from a low caste or tribe on perceived social rank. This study is part of the literature that shows how the internalisation of prejudice and long-lasting discrimination may have impaired individuals’ self-esteem. The results stress the need to account for self-depreciation when assessing the efficiency of affirmative action policies.  相似文献

Recent media attention has increased interest in behavioral, mental health, and academic correlates of involvement in bullying. Yet, there has not been much interest in investigating the co-occurrence of other health-risk behaviors, such as gang membership, weapon carrying, and substance use. The potential influence of contextual factors, such as youth ethnicity, urbanicity, and school characteristics, also has been overlooked in previous research. The current study examined different subtypes of involvement in bullying—as primarily a victim, as primarily a bully, as both a victim and bully, and no involvement—and the association with significant health-risk behaviors, including engaging in violence and substance use, as well as academic problems. The analyses use self-report data from 16,302 adolescents (50.3 % female, 62.2 % Caucasian, 37.8 % African American) enrolled in 52 high schools. A series of three-level HLM analyses revealed that bullies and bully/victims were generally at greatest of risk of being involved in violence, engaging in multiple types of substance use, and having academic problems. These findings extend prior research by emphasizing a potential link between involvement in bullying and multiple health-risk behaviors, particularly among urban and African American high school youth.  相似文献

Research on the role of race and urbanicity in bullying involvement has been limited. The present study examined bullying involvement subgroups that relate to race, urbanicity, and the perceived reason for the bullying. Self-report data were collected from 10,254 middle school youth (49.8 % female; 62.4 % Caucasian, 19.0 % African American, and 5.6 % Hispanic) and latent class analyses were used to identify three subtypes of bullying involvement: low involvement (50 %), victim (31.3 %), and bully-victim (18.7 %). Irrespective of urbanicity (urban vs. non-urban), African American youth were more likely to be members of either the victim or bully-victim classes than the low involvement class. Further exploration of the community context suggested that urbanicity was associated with the increased likelihood of having been racially bullied. Urban bully-victims were also more likely to have been bullied about money than non-urban bully-victims. Findings underscore the importance of addressing both race and urbanicity for culturally sensitive prevention programming.  相似文献
