David Miller 《Ethical Theory and Moral Practice》2005,8(1-2):63-81
Ethical theories normally make room both for global duties to human beings everywhere and special duties to those we are attached to in some way. Such a split-level view requires us to specify the kind of attachment that can ground special duties, and to explain the comparative force of the two kinds of duties in cases of conflict. Special duties are generated within groups that are intrinsically valuable and not inherently unjust, where the duties can be shown to be integral to relationships within the group. Since nations can be shown to meet these conditions, acknowledging special obligations towards compatriots is justified. However for such partiality to be reasonable, it must be balanced against recognition of duties of global justice. These duties include duties to respect human rights and duties of fairness towards non-nationals. Weighing such duties against domestic duties of social justice is not a simple task, and the outcome should depend on the precise specification of the duty at stake. In particular, the duty to respect human rights fragments into four sub-duties whose force when set against local duties is markedly different. 相似文献

时-空整合影响图形识别的眼动研究 总被引:3,自引:1,他引:2
采用眼动追踪的方法对在不同方向(上、下、左与右)及距离(2.0°‘和4.0°视角)上先后出现的特征组合不同的图形识别过程进行了研究。结果表明。首先,对由不同颜色和形状构成的图形的识别受到图形特征组合的影响,视觉系统对颜色和形状的加工存在明显差异,与颜色加工相比,视觉系统需要更多的时间才能完成形状识别。此外,虽然图形识别的速度和准确性受运动方向与距离的影响较小,但在不同运动方向和距离上,视觉系统是通过改变眼动的时间和空间特性来完成识别任务的,视觉系统在识别过程中的这种时间与空间的整合特点还有待于进一步研究。 相似文献

采用个别访谈和问卷法,调查531名5—16岁中国儿童心目中的“中国人”形象以及儿童对中国人身份的喜欢程度和发展趋势。结果表明:(1)总体而言,被调查的5—16岁中国儿童对中国人持积极评价,对自己是一名中国人有积极的情感体验。(2)不同年龄的儿童对中国人形象的积极评价先上升后下降,随后有所回升,其中9—10岁儿童的评价最为积极。(3)儿童对中国人身份的喜欢程度随年龄的增长而下降。(4)对5—10岁的年幼儿童来说,对中国人的评价与喜欢成为中国人的关系不大,11—16岁的年长儿童则能更加紧密地联系两者。 相似文献

This study investigated the development of national identification in children growing up in the Basque Country. The sample consisted of 246 children aged 6, 9, 12 and 15 years old who belonged to three linguistic subgroups: children who spoke only Basque with their parents in their home, children who spoke only Spanish in their home, and children who spoke both Basque and Spanish in their home. It was found that national identifications differed in the three linguistic subgroups. Furthermore, the three subgroups exhibited different evaluations of, and feelings towards, the national ingroup and a number of national outgroups. The positive and affective distinctiveness ascribed to the Basque and Spanish national groups was correlated with the strength of identification with the Basque and Spanish groups, respectively. The attitudes towards national outgroups which were exhibited by these children did not show any changes as a function of age. It is argued that the cognitive‐developmental account of the development of national attitudes is unable to explain the patterns of findings which were obtained, but that social identity theory can explain the correlation between the strength of national identification and the positive and affective distinctiveness which was ascribed to the ingroup.

Within the context of the Basque Country in Spain we examined how ethnic (Basque) and national (Spanish) identification relate to the evaluation of Spaniards, Basques, Andalusians and Catalans. On a sample of adolescent participants we tested a structural equation model which considered identity content (Basque separatism) as a mediator of the relationship between group identifications and group evaluations. While Spanish and Basque identification were associated with a positive evaluation of Spanish and Basque in‐groups, respectively, the evaluation of out‐groups that are relatively similar to the in‐group were not affected by identification. In contrast, dissimilar out‐groups tended to be evaluated more negatively by higher in‐group identifiers. Basque separatism mediated the negative relationship between Basque identification and the evaluation of Spaniards and of Andalusians as a prototypically Spanish subgroup. It is concluded that identification relates differently to the evaluation of different out‐groups, and that the ideological content of identity plays an important role in determining intergroup relations.
