变形的 "文本"--梭戛生态博物馆的人类学观察

1988年10月31日,贵州六枝梭戛生态博物馆作为中国第一座生态博物馆正式建成并对外开放,该馆是中国和挪威两国合作的文化建设项目之一,其目的旨在保护濒临灭绝的长角苗传统文化艺术。2000年7月间,笔者来到梭戛进行为期一周的田野考察,发现该博物馆在建设过程中存在着一些带有普遍意义的矛盾现象。4年之后,笔者再访梭戛,看到当年的矛盾现象不但没有得到化解,反而更加激化和突出,进而走向“变形”。对梭戛生态博物馆运作过程中存在矛盾作人类学的观察和总结,分析和探讨当今传统艺术保护的理论问题,具有十分普遍的现实意义。     

科学执政、民主执政中的依法执政基本途径

依法执政或依法行政,作为执政方式最为直接、最为具体的基本实践环节或途径,在相当范围内反映着科学执政、民主执政的实现程度。这取决于《行政许可法》不打折扣地坚决实施,政府的依法执政职能方式从重管制向重服务转变;职能范围从“全能”向“有限”回归;职能性质由“专断”走向真正“民主”;职能习惯从主观随意转向严格的法治。     

场域论视角下的城市社区建设

场域论社区发展理论认为,社区的本质是社会互动,社区是地域性社会内不同利益群体为了实现共同利益而整合起来的社会互动场域,社区发展的本质就是地域社会内居民的自组织能力的发展。该理论对发展我国社区建设理论具有建设性的启发和借鉴意义。

Using a computer simulation game to teach family time use concepts

A computer simulation game designed to give students insights into family time use concepts has been used in an introductory family resource management class at Ohio State University and other universities. The game allows for planning for time use changes over the family life cycle. The game can give students insights into economic and sociological models of time use. It is possible that future versions of the game could be used in family counseling.His research interests include derivation of optimal decision-making rules for families and family financial management.Her research interests include financial management over the life course including financial ratios, baby boomers, and retirement. She received her Ph.D. in 1993 from The Ohio State University in Family Resource Management.His research interests include the time trade-offs made between couples, financial planning over the life cycle, and the interaction of time and money between families and their home-based businesses. He received his Ph.D. in 1993 from The Ohio State University in Family Resource Management.     

“政策领域-时间维度”双重视角下新能源汽车产业政策央地协同研究

本文以2009—2018年间中央及地方（以北京市等四个地区为例）颁布的263项新能源汽车产业政策为研究样本,从实施领域角度,将产业政策分为财税支持、行业规范、规划引导、监督保障、其他措施等五类,经政策分解,将政策片段与新能源汽车产业链五个环节进行匹配;在此基础上,测度不同时期产业政策央地总体协同度与政策实施领域间的协同度,并通过逐步回归法,确定影响政策协同的各政策效力指标灵敏度。研究表明："中央-北京"和"中央-深圳"的政策措施协同趋势基本一致,产业价值链各环节发展较均衡,而"中央-上海"和"中央-江苏"的政策措施协同趋势基本一致,存在"重使用、轻研发、轻市场"等失调现象;四地区与中央政策措施的协同差异主要体现在研发、生产和回收环节,提升"政策引导"和"保障措施"指标的政策效力有助于提升央地协同水平。根据政策分析,未来政策制定需从优化中央政策推广方式和加强监管保障等政策措施着手,根据产业链不同环节状况适时调整政策措施。     

时代场域·崭新图谱·价值意蕴:全面建设社会主义现代化强国新征程的三维向度

“时代是思想之母,实践是理论之源”。近年来,国内、国际形势均发生了深刻的变革,世情、国情、党情均发生了新的变化。“百年未有之大变局”日益凸显,大发展、大变革、大调整已然成为新时代的鲜明特色。十九届五中全会是在“两个一百年”的历史交汇点上召开的一次具有战略性、全局性、历史性意义的重要会议。十九届五中全会呈现出一些鲜明的特色。其中,“人民至上”的价值取向体现得尤其鲜明。这是马克思主义群众史观在新时代中国的生动诠释。约言之,时代场域、崭新图谱、价值意蕴是全面建设社会主义现代化强国新征程的三维基本向度。     

高Si/C高强度铸铁中C、Si、Si/C的作用及其选择

本文叙述了高Si/C高强度灰铸铁中碳、硅元素存在的形式及其对结晶过程的影响。试验表明,当碳当量一定时,随着Si/C的升高,初生奥氏体枝晶数量增多并且细化和强化,从而构成了强度的基础。该铸铁的强度模式应为“初生奥氏+共晶团”。本文对E型石墨存在的必然性和合理性也进行了讨论。     

Any complete preference structure without circuit admits an interval representation

This article proves that all complete preference structures where the strict preference relation (P) has no circuit admit a representation by intervals of the real line; the rule for deciding whether an interval is indifferent or preferred to another is less straightforward than for interval orders: strict preference is indeed compatible with a certain degree of overlapping of intervals, the allowed degree being specified by means of a so-called tolerance function.     

De minimis and equity in risk

Indices and orderings are developed for evaluating alternative strategies in the management of risk. They reflect the goals of reducing individual and collective risks, of increasing equity, and of assigning priority to the reduction and to the equity of high risks. Individual risk is defined as the (random or non-random) level of exposure to a danger. In particular the role of a lower negligibility level is investigated. A class of indices is proposed which involves two parameters, a negligibility level and a parameter of inequality aversion, and several interpretations of the indices are discussed. We provide a set of eight axioms which are necessary and sufficient for this class of indices, and we present an approach to deal with partial information on the parameters.
