Research trends in nonprofit graduate studies in China: An inside perspective

This paper explores the growth of the academic study of nonprofit management and organizations in China by examining theses and dissertations written in China between 2000 and 2018. Using a keyword search, we collect and review 5,346 abstracts available in the China National Knowledge Infrastructure Thesis and Dissertation database. The number of these theses and dissertations accelerated between 2000 and 2015 and slowed thereafter. Most theses and dissertations focus on the external context of nonprofit organizations (78%) and fewer on nonprofit management per se (22%). Thematic analysis reveals several broad subjects of study including organizational development, the character of the external environment and internal operations, financial and other resource support, and organizational performance. Trends across the 19‐year study period relating to national regions of origin, discipline, and theme are also explored. The development of nonprofit studies in China in some ways resembles the growth of this field in the United States and other western countries in past decades, but with distinct Chinese historical, sociocultural, and geographical characteristics.     

关于族群关系、民族关系与社会关系的关系

"族群"与"民族"概念上存在着交叉关联.族群关系、民族关系都是一种社会关系,但社会关系不一定都构成民族关系,民族关系有时也不一定能够准确地表述特殊的社会关系,族群关系却可以化解民族关系表述的"潜在危机".族群关系、民族关系与社会关系的关系具有多向性、非对称性和动态性的特点.     

地名·历史·观念——基于岭南鬼门关称谓流变史的文化学解读

就现存文献记载看,岭南鬼门关之称谓,大体历经“桂门关”——“鬼门关”——“老鼠关”——“魁星关”——“天门关”等沿革。汉人中原正统观、唐宋贬官文化、岭南科举及道教文化的此消彼长,皆是时人命名关口的社会内因。其中,鬼门之说,显属恶名。解读以上不同性质的称谓,既可资于得见岭南往史;传至今日,又有助于定位玉林区域文化之特色。     

面向多样化需求的M RO 服务资源配置模型与算法

针对大型复杂企业维修任务集的多服务需求点和多样化需求特征,基于服务需求视角,定义一类多服务需求点下的MRO服务资源配置问题,建立以MRO服务提供商整体服务成本为优化目标,同时考虑资源紧张度、信任度和多服务需求点不同工期要求的问题模型;针对模型中的关键参数（即服务成本和资源紧张度）的特征进行分析,并给出相应的度量方法;在此基础上,设计改进的模拟植物生长算法实现求解,算法通过启发式获得初始可行解,并进行敏感性分析。研究结果表明, MRO服务资源配置模型和算法是可行和有效的,服务成本的波动、信任度和资源紧张度的变化对于资源配置结果均有影响,模型能够有效提高维修服务成本的估算能力,同时能够保持MRO服务提供商资源配置的稳定性。     

Approximating soft-capacitated facility location problem with uncertainty

In this paper we devise the stochastic and robust approaches to study the soft-capacitated facility location problem with uncertainty. We first present a new stochastic soft-capacitated model called The 2-Stage Soft Capacitated Facility Location Problem and solve it via an approximation algorithm by reducing it to linear-cost version of 2-stage facility location problem and dynamic facility location problem. We then present a novel robust model of soft-capacitated facility location, The Robust Soft Capacitated Facility Location Problem. To solve it, we improve the approximation algorithm proposed by Byrka et al. (LP-rounding algorithms for facility-location problems. CoRR, 2010a) for RFTFL and then treat it similarly as in the stochastic case. The improvement results in an approximation factor of \(\alpha + 4\) for the robust fault-tolerant facility location problem, which is best so far.     

Efficient polynomial-time algorithms for the constrained LCS problem with strings exclusion

In this paper, we revisit a recent variant of the longest common subsequence (LCS) problem, the string-excluding constrained LCS (STR-EC-LCS) problem, which was first addressed by Chen and Chao (J Comb Optim 21(3):383–392, 2011). Given two sequences \(X\) and \(Y\) of lengths \(m\) and \(n,\) respectively, and a constraint string \(P\) of length \(r,\) we are to find a common subsequence \(Z\) of \(X\) and \(Y\) which excludes \(P\) as a substring and the length of \(Z\) is maximized. In fact, this problem cannot be correctly solved by the previously proposed algorithm. Thus, we give a correct algorithm with \(O(mnr)\) time to solve it. Then, we revisit the STR-EC-LCS problem with multiple constraints \(\{ P_1, P_2, \ldots , P_k \}.\) We propose a polynomial-time algorithm which runs in \(O(mnR)\) time, where \(R = \sum _{i=1}^{k} |P_i|,\) and thus it overthrows the previous claim of NP-hardness.     

集群剩余与企业集群内部协调机制

企业集群内部协调既不同于市场上价格机制的无形之手,又不同于企业内部行政命令的有形之手。本文分析指出,集群内部协调的目标在于追求集群剩余,并根据企业行为的规律性对集群剩余进行了分析;介绍集群内部的各种协调机制,在此基础上,分析协调机制与集群剩余实现之间的关联。     

系统风险联动分析:以股市和银行间债市为例

金融子市场间系统风险的联动是决定目前监管政策趋向的一个重要因素,本文以中国银行间债市面向非金融机构开放为例,基于我国金融市场分业监管的现状,对两个股市和银行间债券市场之间的波动联动性进行了实证检验,并在此基础上,试图基于分析结果对金融子市场之间的资金流动现状做出分析和判断。
