Politics and Positionality: Engaging with Maps of Meaning

This article considers critical social work education within the context of the challenges associated with the increasingly neoliberal, corporate and competitive nature of higher education and human service provision. The metaphor of maps is used as a framework for exploring the potential for transformational learning opportunities associated with alternative ways of thinking about teaching and learning. Countering the neoliberal tendency to depoliticise, metaphors of maps and map-reading, as discussed here and applied to social work education, evoke diverse perspectives and engagements in relation to the politics of knowledge, knowing, theory and practice. In emphasising the partiality of knowledge, the indivisibility of the ‘knower’ and the ‘known’ and, as such, the personal and the professional, efforts to cultivate critical consciousness, thus, enable different conversations. The central premise of this article is that in offering opportunities for engagement which open up rather than close down the space for meaningful dialogue, educators may contribute, in profound ways, to both student development and the (re)shaping of public discourse.     

组织结构变革中的路径依赖与路径突破

组织结构变革是组织管理研究中的核心问题之一。结构变革中的路径依赖形成与突破涉及不同层面的众多因素,现有研究中缺乏将组织微观动力机制与组织结构变革进行整体分析的视角。但研究发现,组织结构系统内生地蕴含着路径依赖和路径突破的特性。组织内部因组织结构惰性而导致的路径依赖具有两面性。当外部环境发生变化时,组织变革领导者必须认识到路径依赖产生的积极影响和消极影响,通过组织学习,突破行为惯性和管理认知惯性,充分发挥路径创造和路径突破方面的能动性,"有意识地偏离"组织原有的路径,积极进行路径突破和创造。     

Knowledge Structures, Social Information Processing, and Children's Aggressive Behavior

Although a multitude of factors may be involved in the development of children's violent behavior, the actual aggressive act is preceded by a decision-making process that serves as the proximal control mechanism. The primary goal of this longitudinal study was to understand the nature of this proximal control mechanism involved in children's aggressive acts by focusing on two aspects of social cognitions: social information processing and stored knowledge (i.e., internal knowledge structures that are the latent memories of past events). It was hypothesized that: (1) children with hostile knowledge structures will display more biased patterns of aggressive social information processing than children whose knowledge structures are less hostile and negative; (2) children who display hostile knowledge structures will behave in chronically aggressive ways; and (3) the development of hostile knowledge structures and hostile patterns of social information processing contribute to the stability of aggressive behavior and thus partially mediate the relation between early and later aggressive behavior. 585 boys and girls (19% African-American) were followed from kindergarten through eighth grade. Results from this investigation support the hypotheses and are discussed in terms of the significance of the inclusion of knowledge structures in our theories of the mental processes involved in children's violent behaviour.     

A comparative study of series arima/mlp hybrid models for stock price forecasting

ABSTRACT

Series hybrid models are one of the most widely-used hybrid models that in which a time series is assumed to be composed of two linear and nonlinear components. In this paper, the performance of two types of these hybrid models is evaluated for predicting stock prices in order to introduce the more reliable series hybrid model. For this purpose, ARIMA and MLPs are elected for constructing series hybrid models. Empirical results for forecasting three benchmark data sets indicate that despite of more popularity of the conventional ARIMA-ANN model, the ANN-ARIMA hybrid model can overall achieved more accurate results.     

Does Modern Organization and Governance Threat Solidarity?

This article focuses on solidarity behaviours of employees to team members (horizontal solidarity behaviour) and to their manager (vertical solidarity behaviour). The question is asked to what extend and how are both types of solidarity related to three aspects of modern organization and governance: dual earner families, flexible labour contracts, and formal and informal governance structures. Survey data of 17 Dutch organizations (N = 1347) show in relation to dual-earner families that having children has a positive relationship with horizontal solidarity behaviour, and working overtime has a positive relationship with vertical solidarity behaviour. Related to the flexible labour contracts, no relationship was found with type of labour contract and expected years within the organization. Finally, some traits of informal and formal governance structures, namely information on rules and the presence of explicit fair play rules are fond to be positively related to solidarity.She worked on this article during a visit at the University of New South Wales, Sydney, Australia.     

不同权力结构和联盟策略下风险规避型闭环供应链决策

本文旨在探讨不同渠道权力结构和联盟策略下风险规避型闭环供应链的决策问题。考虑到产品需求和废旧产品回收的不确定性及决策者的风险规避特性,在制造商主导、零售商主导及制造商和零售商势力均衡三种情形下,分别构建了制造商和零售商联盟与不联盟时的闭环供应链博弈模型,获得了六个博弈模型下的均衡解,对比分析了不同模型下产品定价、废旧产品的最优回收价格和供应链及其成员的期望收益。研究结果表明,在制造商和零售商不联盟的情形下,决策者的风险规避程度增加能够缓解双重边际效应,供应链期望收益与风险规避程度正相关,而在制造商和零售商联盟的情形下,供应链期望收益与风险规避程度负相关;制造商和零售商不联盟时,制造商和零售商势力均衡的渠道权力结构对消费者最有利,而制造商和零售商联盟时,制造商和零售商势力均衡的渠道权力结构对消费者最不利;制造商和零售商权力结构不对等时最优价格决策之间的关系与制造商和零售商的风险规避程度有关;供应链期望收益在制造商和零售商势力均衡下最大,制造商期望收益在制造商主导的渠道权力结构下最大,零售商期望收益在零售商主导的渠道权力结构下最大。

对生命圆融境界的追求——对《封锁》“圆型结构”的阐释

＂和合＂是中国文化的主导精神,＂和谐＂既是事物本该具有的状态,又是一切事物发展、变化的最终目标和结果,求＂圆＂就是＂和谐＂这个审美文艺理论的一个表现。张爱玲《封锁》具有＂圆型＂构思,体现了作者对＂身心平衡＂这种生命圆融境界的追求。本文从整体性、对比性、运动性思维三个方面探析了《封锁》的圆型构思特征,苍凉的意味使圆型结构本身显得饱满、丰富,充满艺术感染力,从而揭示出小说所蕴含的独特内涵和现实意义。
