我国转型期地方性单项体育协会发展模式研究——基于宁波市篮球协会的个案分析

以宁波市篮球协会为个案,探讨了宁波市篮球协会的发展模式,在此基础上提出了转型期地方性单项体育协会的发展策略,包括赛事推动、共建共赢、用足政策、营造文化、“班子效应”等。认为在当前经济条件下,协会的发展还是离不开“公助”,需要政府经济上的帮助和政策上的扶持,也需要“依托社会、联姻企业”谋求共同发展。而协会的权威性,一方面来自政府的职能转移和授权,另一方面还来自协会自身的影响力。     

Estimation of value-at-risk using single index quantile regression

ABSTRACT

Value-at-Risk (VaR) is one of the best known and most heavily used measures of financial risk. In this paper, we introduce a non-iterative semiparametric model for VaR estimation called the single index quantile regression time series (SIQRTS) model. To test its performance, we give an application to four major US market indices: the S&P 500 Index, the Russell 2000 Index, the Dow Jones Industrial Average, and the NASDAQ Composite Index. Our results suggest that this method has a good finite sample performance and often outperforms a number of commonly used methods.     

深化对劳动和劳动价值论认识的几点思考

本文针对当前经济理论界出现否定劳动价值论的两种倾向,从社会主义经济是商品经济与联合劳动的统一;利润共享、“见物不见人”的双重产权制度的角度,阐明劳动价值理论是坚持、完善社会主义制度的理论基础。同时强调必须紧密结合我国社会主义特征和初级阶段国情特征,来深化认识、充分发挥劳动价值理论对我国经济改革的指导作用。     

也说“合体象形”

“象形字只能是不可分割的独体之文”的观点具有代表性。而“独体为文,合体为字”之“独体”应视为一个相对的概念。象形字中确实存在一类为强化实物的区别性特征而在目的物上添加连带部件的准独体字,所谓“合体象形”是对这类象形字的传统叫法。这个名称中的“合体”容易与“合体为字”中的“合体”造成混淆,因而应拿“加体象形”取而代之。     

The Intersubjective Action of Case Advocacy and Engagement in a Working Alliance

This article presents a viewpoint for explaining the positive associations between case advocacy and the engagement in a working alliance of low‐income single mothers at‐risk for physical abuse of their children. Utilizing narrative vignettes from a qualitative study about clinical social workers’ experiences in engaging this population, the article suggests that client/worker partnerships in case advocacy enhanced opportunities for client/worker mutuality and for worker capacities to experience and communicate empathy to their clients. Theoretical constructs from Daniel J. Stern’s infant research and neuroscience are then applied to suggest an intersubjective framework for understanding what occurred.     

Employment and Parenting Among Current and Former Welfare Recipients

Abstract

This two-wave longitudinal study investigated whether low-wage employment predicts improvements in depressive symptoms and parenting style in a sample of 178 current and former single-mother welfare recipients with a preschooler at Time 1 and an early-elementary school-age child at Time 2. Findings suggest that participation in employment is associated with improvements in single mothers' psychological well-being and parenting style over time. However, in this study, employment at Time 1 (baseline) was more beneficial with respect to psychological and parenting outcomes than was employment (and earning more) at Time 2, except for mothers who were not employed at Time 1 and who became employed by Time 2. For these mothers, employment at Time 2 predicted a decrease in depressive symptoms and, through the latter, less negative parenting style. Mothers with higher educational attainment were more likely to be employed at Time 1 (which predicted higher levels of employment and pay at Time 2) and, among those not employed at Time 1, more likely to become employed (and earn more) by Time 2. Implications of these findings for welfare reform are discussed.     

浅析单亲大学生心理问题及干预机制

随着社会上越来越多的单亲家庭的出现,单亲大学生的心理问题日益凸显出来。他们在成长过程中出现政治信仰不坚定、法制观念淡薄、社会责任感缺失、不健康的性格特征及学习心理障碍等突出问题。因此,探讨单亲大学生心理问题的干预机制,有助于促进他们心理健康的发展和整体素质的提高。     

流动性过剩与全球失衡的单变量冲击分析

基于货币稀释理论建立流动性过剩与全球失衡的一般均衡模型,分析流动性过剩、储蓄、消费、金融发展、经济增长等因素对世界经济的冲击影响,证明了十个重要命题.通过这些命题的组合和演绎,能够从理论上全面、科学和合理地解释世界经济中出现的经济现象.文章的结论不仅能够覆盖相关文献的主要观点,而且将文章提出的理论渗透到社会再生产的四个环节,揭示了当今世界经济的发展逻辑.美国利用美元的国际储备货币地位,在分配中无偿获得了世界经济的发展成果.美国依靠比较优势发展的虚拟经济,在与别国实体经济的交换中获利,支持了美国的过度消费,导致美国经常账户赤字,造成全球失衡,对金融危机负有主要责任.     

Transforming an MRP plan into a short-term schedule

A new approach for transforming MRP orders, planned periodically, e.g. on a weekly base, into a detailed sequence of jobs is presented. In this model for a single machine environment, the jobs are partitioned into families and a family specific set-up time is required at the start of each period and of each batch, where a batch is a maximal set of jobs in the same family, that are processed consecutively. An integer program is formulated for both the problem of minimizing the number of overloaded periods and the problem of minimizing the total overtime. These programs generate benchmark results for the heuristic approach. A heuristic model is developed that constructs a schedule in which overloaded periods are relieved and set-up time is saved. In this approach, the job sequence is constructed by repeatedly solving a knapsack problem. The weights used in this knapsack problem relate to the preferred priorities of the jobs not yet scheduled and determine the quality of the final sequence. The different features of the heuristic model are compared using a large set of test problems. The results show that the quality of the final sequence depends on an appropriate choice for the weights.     

基于峰值负荷的签派员席位任务分配问题

本文研究的问题来源于航空公司运行控制中心的签派部门,签派员在放行航班时,既要保证航班的正点起飞,又要调节放行航班的工作劳动强度保证放行的质量,使航班在安全状态下运行。这里放行航班的工作劳动强度为单位时间内的工作时间,峰值负荷即劳动强度最大值。峰值负荷过高则工作紧张,进而推断该放行席位的任务分配不合理。文中将问题描述为任务有优先序的单机排序问题,每个任务都有一个到达时间（release time）、截止期限（deadline）和处理时间（procession time）,处理时间因任务的不同而不同,目标是在绝对不准延误完成任务前提下,使单位时间的峰值负荷最小。在使单位时间峰值负荷最小的目标下,本文提出了一个有效算法,并证明该算法下的任务安排是最优安排。
