《金瓶梅》中的“岂有此理”和“多”

“岂有此理”、“多”是汉语的常用词 ,《金瓶梅》对此使用也很频繁 ,但除常见用法外 ,还有特殊情况。“岂有此理 (礼 )”更多的是在礼貌场合表示谦逊、推让的客套用语。“多”时常作表全部的范围副词 ,和“都”相同。笔者拿同时代稍晚的“二拍”作比较 ,认为这与方音有关 ,而前人对“多”的解释未注意这一点 ;“多”的使用也透露了《金瓶梅》版本方面的信息     

刑事证人保护问题探析

刑事证人保护是刑事司法中的一个重要问题，证人作证难、出庭难问题与其有着直接关联，我国立法只强调证人作证义务，忽视对证人的保护，合理解决刑事证人保护问题是审判方式改革和人权保障的必然要求。为此，必须建立完整的刑事证人保护制度，明确刑事证人保护对象范围、权利保障内容、保护机构及措施等，以使证人的人身、人格、财产权益得到有效的保护。

Cr13白口铸铁获得屈氏体的研究

铸态屈氏体高铬铸铁用于水泥磨球已经问世。本文对 Cr13白口铸铁如何得到屈氏体基体组织进行了试验研究。在 Cr 含量一定时,随着 Cr/C 减小,砂型浇注时,过冷奥氏体铸态转变为屈氏体量逐渐增加,金属型浇注时则不易转变。当 Cr/C≤4时,砂型和金属型试样铸态均能得到全部的屈氏体基体。金属型开型后铸件置于550℃炉内保温一定时间随炉冷却,高的 Cr/C 材质亦能得到屈氏体基体组织,但增加了生产工序。加入微量铝可使含碳量在2.6～3.0%的中碳材质砂型和金属型铸件铸态得到屈氏体基体,并有较好的综合性能。     

Child-Oriented Family Therapy Outcome Research: Comparisons Between Brief Family Therapy and an Alternative Treatment

This paper is concerned with outcome research in child-oriented family therapy. Nine investigations comparing brief family therapy with an alternative treatment were critically reviewed. All of the studies were vulnerable to criticisms on design and methodological grounds. Problem areas included: specification of therapeutic techniques, confounding of therapeutic variables, equivalence of therapist factors, measurement of outcome, adequacy of measures and appropriate use of control groups. All studies concluded that childhood problems could be treated successfully with brief family therapy techniques. However, in the light of the design problems listed above, these conclusions should be treated tentatively.

Joint Initial Stocking and Transshipment—Asymptotics and Bounds

A common problem faced by many firms in their supply chains can be abstracted as follows. Periodically, or at the beginning of some selling season, the firm needs to distribute finished goods to a set of stocking locations, which, in turn, supply customer demands. Over the selling season, if and when there is a supply‐demand mismatch somewhere, a re‐distribution or transshipment will be needed. Hence, there are two decisions involved: the one‐time stocking decision at the beginning of the season and the supply/transshipment decision throughout the season. Applying a stochastic dynamic programming formulation to a two‐location model with compound Poisson demand processes, we identify the optimal supply/transshipment policy and show that the optimal initial stocking quantities can be obtained via maximizing a concave function whereas the contribution of transshipment is of order square‐root‐of T. Hence, in the context of high‐volume, fast‐moving products, the initial stocking quantity decision is a much more important contributor to the overall profit. The bounds also lead to a heuristic policy, which exhibits excellent performance in our numerical study; and we further prove both the bounds and the heuristic policy are asymptotically optimal when T approaches infinity. Extension to multiple locations is also discussed.     

A Bivariate Distribution Family with Specified Correlation Coefficient and Given Marginals

For given continuous distribution functions F(x) and G(y) and a Pearson correlation coefficient ρ, an algorithm is provided to construct a sequence of continuous bivariate distributions with marginals equal to F(x) and G(y) and the corresponding correlation coefficient converges to ρ. The algorithm can be easily implemented using S-Plus or R. Applications are given to generate bivariate random variables with marginals including Gamma, Beta, Weibull, and uniform distributions.     

少数民族搬迁移民儿童社会融入何以可能——基于优势视角的融入机制与支持网络构建

在后扶阶段,影响我国少数民族搬迁移民儿童社会融合的主要因素已经由政府政策、资金等外部宏观因素转变为家庭、学校及社区等微观因素。研究少数民族移民儿童社会融合的关注点要由聚焦于政策、制度等宏观领域转至家庭、学校等微观场域,研究视角也理应由聚焦制度排斥的问题视角转向关注社会融入的优势视角。由此,根据优势视角理论及布朗芬·布伦纳的个体发展模型,在正视移民儿童社会融入问题和困难的前提下,剖析促进搬迁移民少数民族儿童社会融入的动力机制,挖掘移民儿童所具有的内外优势与资源,构建促进其社会融入的社会支持网络。
