简析《史记》中的社会饮食结构 ——以关中地区为中心

《史记》作为百科全书,对从传说中的黄帝到汉武帝中期长达三千多年的社会事象作了全景描绘,涉及各个阶层、各种人物的生活衣食住行的方方面面。作为生活头等的“食”在这部巨著中也是无处不在,对饮食（主要是“食”的方面）活动、礼仪、方式、对象和器具等都作了记载,涵盖了物质层面、制度层面、行为层面和精神文化层面。从《史记》记载来看,总体上可以说,我国古代逐渐形成以谷物为主食,肉类、蔬菜瓜果为副食的饮食方式。     

Books on probability ideas are reviewed

In this paper, semiparametric methods are applied to estimate multivariate volatility functions, using a residual approach as in [J. Fan and Q. Yao, Efficient estimation of conditional variance functions in stochastic regression, Biometrika 85 (1998), pp. 645–660; F.A. Ziegelmann, Nonparametric estimation of volatility functions: The local exponential estimator, Econometric Theory 18 (2002), pp. 985–991; F.A. Ziegelmann, A local linear least-absolute-deviations estimator of volatility, Comm. Statist. Simulation Comput. 37 (2008), pp. 1543–1564], among others. Our main goal here is two-fold: (1) describe and implement a number of semiparametric models, such as additive, single-index and (adaptive) functional-coefficient, in volatility estimation, all motivated as alternatives to deal with the curse of dimensionality present in fully nonparametric models; and (2) propose the use of a variation of the traditional cross-validation method to deal with model choice in the class of adaptive functional-coefficient models, choosing simultaneously the bandwidth, the number of covariates in the model and also the single-index smoothing variable. The modified cross-validation algorithm is able to tackle the computational burden caused by the model complexity, providing an important tool in semiparametric volatility estimation. We briefly discuss model identifiability when estimating volatility as well as nonnegativity of the resulting estimators. Furthermore, Monte Carlo simulations for several underlying generating models are implemented and applications to real data are provided.     

THE RELEVANCE OF THE CONCEPT OF DISSOCIATION IN CHILD PROTECTION

This paper explores one aspect of unresolved trauma, namely dissociation. Its relevance to child protection is discussed with reference to two aspects: emotional neglect and choice of partner. There is an exploration of the implications for both assessment and treatment. The central place of shame in relation to dissociation is also explored. It is argued that dissociation is an important concept in child protection assessments and that social work assessments should be alert to this.     

吉伯德-萨特思韦特防策略不可能性定理的逻辑初探

自20世纪70年代吉伯德-萨特思韦特防策略不可能性定理确立后，引起了数学、经济学、计算机科学和哲学等诸多领域中学者的广泛关注。然而，在国内外文献中，对吉伯德-萨特思韦特防策略不可能性定理的逻辑研究还比较少。基于此，借助公理化的方法探讨吉伯德-萨特思韦特防策略不可能性定理，并形式化地给出定理的内容和证明，力图把精细的逻辑推理应用于复杂的过程分析中，使防策略投票这一过程形式化、清晰化，以期能指导人们进行合理、有效的决策活动。     

民汉双语诉讼规则之探索

我国宪法赋予了公民用自己的民族语言文字参加诉讼的权利，目的在于实现民族平等、促进民族团结、禁止民族分裂、保护中华民族语言文化的多样性，进而提高我国的文化软实力。通过调查民族语言文字诉讼司法实务，发现当前存在着少数民族语言文字诉讼程序混乱、不符合诉讼原理等问题，不利于民族语言文字诉讼权利的实现。究其原因，在于该诉讼制度缺乏程序保障。为了确保民族语言文字诉讼权利的有效实现，应设立“民汉双语诉讼规则”，以为司法机关提供统一的操作规范。民汉双语诉讼规则应该明确民汉双语诉讼的概念、类型以及民族语言文字诉讼权利的内容，并且根据不同诉讼类型有针对性地设置审判语言与诉讼语言的适用规则。     

慈善与慈善组织的秩序维度与政策选择

人是生活在秩序维度的，人的生命的价值，尤其是劳动力的价值，与处于不同秩序维度有关系。公共慈善也是如此。它有原始秩序的维度，也有扩展秩序的维度，在不同的维度里，有不同的价值。从特朗普家族慈善基金会的命运，可以见出慈善和慈善组织涉及到的不同维度秩序的冲突。更好地发展慈善和慈善组织，需要解决冲突，在不同的秩序维度里，处理好各个方面的关系。     

Food in Foster Families: Care,Communication and Conflict

This study explores the significance of food and mealtimes in relation to the transition into foster care and the therapeutic settling of the child in a new family. In doing so, we draw upon an in‐depth, qualitative case study of 10 experienced foster families in the UK focusing on what helped them to be successful. At the time of the study, there were 16 foster children, aged 9–16, living with the families. Data collection included semi‐structured qualitative interviews and audio‐diaries with all family members who wished to be involved as well as eco‐maps produced by the young people. Thematic analysis and data extracts are reproduced in the study to demonstrate that meals and food preferences can function to affirm identities, membership and boundaries of family life as well as provide a site of conflict and control.     

Ideologies & Narratives in Relation to ‘Fat’ Children as Bullies, ‘Easy Targets’ and Victims

In this study, we explore narratives in relation to ‘fatness’, drawing on focus group interviews with parents, early years practitioners, teachers and young people. The study is located in a larger study on bullying and resilience, with no specific focus on obesity or ‘fatness’. Analysis of the interview data highlighted a recurrent focus on ‘fatness’ within the participants’ narratives, by labelling and stigmatising the ‘fat kid’ and ‘bigger children’. We conclude that obesity and fatness, as abnormalities, are now included in commonsense talk in relation to ‘easy targets’, victims and bullies.     

Maternal Experiences of Parenting Girls who are Perceived as Overweight or at Risk for Becoming So: Narratives of Uncertainty,Ambivalence and Struggle

This work explored U.S. mothers’ experiences of parenting young adolescent girls who are perceived by their mothers as overweight or at risk for becoming so. Data were collected via in‐depth interviews with 13 mothers and were analysed using a constructivist grounded theory approach. Many mothers experienced socializing their daughters about issues of the body, weight, diet, and health as marked by uncertainty, ambivalence and struggle, particularly relative to four subthemes: mothers’ embodiment as challenge to ‘good mothering’, negotiating a dilemma of the ‘healthy mind’ versus the ‘healthy body’, managing discipline: how much to intervene?, and the challenge of interpersonal dynamics.     

Ethical living: relinking ethics and consumption through care in Chile and Brazil

Mainstream conceptualizations of ‘ethical consumption’ equate the notion with conscious, individual, market‐mediated choices motivated by ethical or political aims that transcend ordinary concerns. Drawing on recent sociology and anthropology of consumption literature on the links between ordinary ethics and ethical consumption, this article discusses some of the limitations of this conceptualization. Using data from 32 focus groups conducted in Chile and Brazil, we propose a conceptualization of ethical consumption that does not centre on individual, market‐mediated choices but understands it at the level of practical outcomes, which we refer to as different forms of ‘ethical living’. To do that, we argue, we need to depart from the deontological understanding of ethics that underpins mainstream approaches to ethical consumption and adopt a more consequentialist view focusing on ethical outcomes. We develop these points through describing one particular ordinary moral regime that seemed to be predominant in participants’ accounts of ethics and consumption in both Chile and Brazil: one that links consumption and ethics through care. We show that the moral regime of care leads to ‘ethical outcomes’, such as energy saving or limiting overconsumption, yet contrary to the mainstream view of ethical consumption emphasizing politicized choice expressed through markets, these result from following ordinary ethics, often through routines of practices.
