"有点幻灭"但"并没动摇"--重新解读1927年顷茅盾的思想与创作

对1927年顷茅盾的思想与创作的历史评价,历来存在两点分歧:一是怎么理解茅盾所说的我“有点幻灭”,但“并没动摇”;二是对他失去党的组织关系的原因和应作何评价。两者都应站在历史唯物主义立场上,放到当时中国革命现实、国际共运与中共党史史实大背景上作宏观考察。一是茅盾“幻灭”的,是他参与建党时就形成的“革命速胜论”,即认为中国革命是一步到位的“无产阶级革命”,但是他的共产主义信仰从未动摇过。二是茅盾失去党的组织关系的主要原因,在客观方面不在主观方面,因为他公开反对一度控制中共中央的“左”倾盲动主义路线,在具此“左”倾思想的党内负责同志看来,不能认为是“表现得好”而予以恢复党的组织关系。这一切充分表现出茅盾坚定的共产主义信念,勇于自我批评,勇于反对错误路线的难能可贵的政治品格与高尚人格。

基于二阶段随机规划的城市医疗废弃物回收网络设计

城市医疗废弃物日益增加,且回收需求量受诸多因素的影响,难以准确预测,假定回收需求为确定值的医疗废弃物网络优化设计不能与实际需求相匹配。本文考虑了离散随机参数环境下,医疗回收网络设计中选址规划、分配计划及运输规划的协同优化问题,建立了以选址成本、运输成本最小为目标,设施与车辆能力限制为约束的二阶段随机规划模型。根据模型特点,设计了基于Benders decomposition的求解算法,同时,设计了一系列加速技术用于提高算法的求解效率。最后,以国内某城市医疗回收网络为背景设计算例,检验本文模型和求解策略的可行性和有效性。结果表明：相比确定性规划,随机规划的解能够节约总成本,结合一系列加速技术的Benders decomposition方法比CPLEX与纯的Benders decomposition更有优势。     

指人名词充当主语的名词性谓语句

名词直接充当谓语是汉语所特有的现象,我们称这种句式为名词性谓语,亦即“ＮＰ１—ＮＰ２。”句式。并非所有的名词性词语都能直接作谓语句,所以,本文着重讨论ＮＰ２所特有的结构、意义类型及其述谓性特征,从而对“ＮＰ１－ＮＰ２”句式作出一定的描写和解释。     

A Class of Efficient Non-parametric K-sample Tests for Multivariate Counting Processes with Frailties

A K -sample testing problem is studied for multivariate counting processes with time-dependent frailty. Asymptotic distributions and efficiency of a class of non-parametric test statistics are established for certain local alternatives. The concept of efficiency is to show that for every non-parametric test in this class, there is a parametric submodel for which the optimal test has the same asymptotic power as the non-parametric one. The theory is applied to analyse a diabetic retinopathy study data set. A simulation study is also presented to illustrate the theory     

How well is debt managed by nonprofits?

Little is known about why nonprofits accrue debt, how much they owe, and whether the funds they borrow are used productively. This article distinguishes between productive, problematic, and deferred debt. Employing a data base representative of 114,726 tax-filing charitable nonprofits in the United States in 1986, it examines the pervasiveness of nonprofit debt and the relation between this debt and nonprofit financial health. The analysis finds that over 70 percent of the nonprofits hold debt, the distribution of this debt is highly concentrated, and the level of debt and leverage varies with asset size and type of activity. Nonprofits with higher leverage and absolute debt levels are financially healthier than those with lower levels. While the analysis does not determine whether financially stronger nonprofits are better able to borrow, the results support the view that borrowing in the nonprofit sector is economically efficient.     

One-dimensional optimal bounded-shape partitions for Schur convex sum objective functions

Consider the problem of partitioning n nonnegative numbers into p parts, where part i can be assigned n_i numbers with n_i lying in a given range. The goal is to maximize a Schur convex function F whose ith argument is the sum of numbers assigned to part i. The shape of a partition is the vector consisting of the sizes of its parts, further, a shape (without referring to a particular partition) is a vector of nonnegative integers (n₁,..., n_p) which sum to n. A partition is called size-consecutive if there is a ranking of the parts which is consistent with their sizes, and all elements in a higher-ranked part exceed all elements in the lower-ranked part. We demonstrate that one can restrict attention to size-consecutive partitions with shapes that are nonmajorized, we study these shapes, bound their numbers and develop algorithms to enumerate them. Our study extends the analysis of a previous paper by Hwang and Rothblum which discussed the above problem assuming the existence of a majorizing shape.
