读《永生医院》，想象“永生”——从“写什么”说到“生生”

文章以郝景芳在《永生医院》中遭遇到的"永生"问题为切入点,在中西方生命哲学的大背景下,对当代科技手段制造出来的"新人"所带来的文化冲击和个体生命的意义危机进行了深入的思考。作者从中国传统的"生生"哲学出发,深入剖析了以技艺人的工作经验为基础的古希腊"制造"哲学借助于当代科技手段造成的生命哲学危机,指出"永生"不是生命的最高目标,唯有在变动不息的"生生"之中,才有生命的真实意义。     

“三治融合”乡村治理体系的“法治”进路

在乡村振兴战略的推进过程中,我国逐渐形成了"自治""法治""德治"相结合的"三治融合"乡村治理体系。其中,"法治"作为"三治融合"的中坚力量,在我国乡村治理体系的"自治"与"德治"之间起到了承上启下的作用。由于乡村法治体系在立法、执法、守法等方面均存在客观局限性,使得在推进乡村治理体系建设的过程中存在"法治"薄弱化、虚置化、边缘化的困境。要解决上述问题,必须完善中国特色社会主义乡村法律体系,提高乡村治理主体法治能力,加强乡村法治文化建设,充分发挥"法治"的衔接作用,实现"三治融合"的协调统一。     

“健康丝绸之路”构建的“政府—社会”复合路径

借鉴社会运动理论,可探索一种融合了政府自上而下和社会自下而上进程的“政府—社会”复合路径,以构建“健康丝绸之路”。社会运动理论的三种视角可为这种复合路径的具体实施与需要关注的环节带来重要启发：首先,当前新冠肺炎疫情的跨国传播暴露了全球公共卫生治理体系存在的严重不足,凸显出构建补充型国际卫生合作模式的必要性与紧迫性;其次,推进“健康丝绸之路”的构建,需要政府和社会层面的协作,将“一带一路”沿线国家的资源充分调动起来,形成优势互补与资源共享。与此同时,要推进健康话语体系的完善,如倡导和促进“人类卫生健康共同体”理念的传播,通过话语和心理共鸣等民心相通的途径,促使国际社会采取联合行动以共同应对全球公共卫生危机。     

房地分离：宅基地流转之钥——以宅基地使用权继承之困局为切入点

尽管具有一定保障性,但宅基地制度的首要目标在于经济管理,其表面上强调“户有所居”,实际是“户有定居”。宅基地上使用权所承载的管理性与农民自费建造农房所有权的私权性,存在内在的矛盾,不应适用房地一体规则,因为后者遵循着传统民法应对市场交易的基本逻辑。自然资源部所发布的文件明确了宅基地使用权可以由城镇居民继承,内核乃是基于房地一体,以房屋所有权的可继承带动宅基地使用权的可继承,颇为冒进。宅基地上所有权与房屋使用权应当分离,这将为宅基地的流转与乡村振兴提供新的契机：农房的自由流转加上宅基地使用权的农民保有,将最大限度地在现有阶段实现市场与制度的有机契合;对于取得农房的所有权人,在房地分离之下,可以借助对宅基地使用权的法定租赁来设计合理的权利结构。     

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.     

A fast splitting procedure for classification trees

This paper provides a faster method to find the best split at each node when using the CART methodology. The predictability index is proposed as a splitting rule for growing the same classification tree as CART does when using the Gini index of heterogeneity as an impurity measure. A theorem is introduced to show a new property of the index : the for a given predictor has a value not lower than the for any split generated by the predictor. This property is used to make a substantial saving in the time required to generate a classification tree. Three simulation studies are presented in order to show the computational gain in terms of both the number of splits analysed at each node and the CPU time. The proposed splitting algorithm can prove computational efficiency in real data sets as shown in an example.     

The impact of P.L. 93-641, the National Health Planning and Resources Development Act, upon health and mental health programming

Federal legislation regarding health care in the U.S. has increased rapidly in the past few years. A major law with potential far-reaching effects was enacted as a result of increasing legislation and rising health care costs. This law,The National Health Planning and Resources Development Act,has created a network of over 200 local, mostly nongovernment units, called health systems agencies. These agencies are responsible for areawide health planning, plan implementation, review and approval of federal health care expenditures for local programs, and facilities review. They will affect health and mental health programs at the local level. The article is directed to local health and mental health care providers who will, of necessity, deal directly with the local HSA's.
