An Approach to Value-Based Modeling of Information Flows     

NABIL KAMEL MURALI MOHAN NARASIPURAM KRANTI TORASKAR 《The Information Society》2013,29(1):93-105

This article presents a new approach to modeling information flows within today's information systems environments characterized by electronic commerce. We treat information as a resource whose value is fundamentally multidimensional in nature. In this article we consider the economic and psychological dimensions of the value of information. It is argued that it is meaningless to model the value of information in isolation away from the context and the specific parties between which this information is exchanged. We therefore focus exclusively on modeling information flows rather than information itself. To achieve this, we propose a formal framework for describing transactions involving information flows. The framework consists of a generalized model for representing information transactions and for defining a set of fundamental properties of multiparty transactions. These properties are fairness, constructiveness, and monopoly. Where applicable, they are defined for individuals, transactions, and a system of transactions. The proposed model reveals the nature of individual transactions and markets, and consequently has important implications for simulation of market scenarios and to help arrive at effective policies for pricing and market regulations.  相似文献

高校奖助学金制度的价值导向浅析     

王奥 《四川职业技术学院学报》2012,22(2):103-105

奖助学金制度是校园文化精神引领的重要体现,其价值取向和激励方向不但是制度能否公平合理实施的关键,而且会影响奖助学金的评定工作和学生的日常管理和教育。奖助学金评选中的价值"众生相",削弱了奖助学金应有的人文关怀和价值引导功能。奖助学金制度要发挥其正向激励和价值导向功能,从完善奖励机制体系、加强过程教育、建构后期管理机制、塑造精神奖助体系来实现物质帮助和精神提升的双重价值引导效果。  相似文献   

Development of children’s moral evaluations of modesty and self-promotion in diverse cultural settings     

《Journal of moral education》2012,41(1):61-78

This cross-cultural study of the moral judgements of Mainland Han-Chinese, Chinese-Canadian, and Euro-Canadian children aged seven to 11 examined the evaluations of narrative protagonists’ modest lies and self-promoting truthful statements in situations where they had done a good deed. The story characters had thus either lied or told the truth about a prosocial act that they had committed. Chinese children judged modest lies more positively and boastful truths less positively than Euro-Canadian children. Chinese and Chinese-Canadian children rated immodest statements more negatively than did Euro-Canadian children. The cultural differences were greatest with the oldest children. Chinese children rated modest lies significantly more positively than either Canadian group who did not differ from each other but an interaction between age and culture revealed the three groups to be significantly different at age 11 with Chinese children most positive, followed by Chinese-Canadian children, and with Euro-Canadian children evaluating modest lies least positively. Cultural strictures and acculturation factors respecting modesty and self-enhancement are reflected in these differences.  相似文献   

Peer Assessment of Children's Prosocial Behaviour     

《Journal of moral education》2012,41(1):47-60

The study was designed to examine 8-12-year-olds' peer assessments of prosocial behaviour and their relationship to self-assessments, teacher-assessments and peer acceptance. Although prosocial behaviour has been studied for many years, it has been narrowly operationalised and research has tended to lack ecological validity. To rectify these weaknesses, child-generated normative prosocial behaviours were used to generate peer nomination items for the purpose of rating children's performance of prosocial behaviour in peer interactions. Children also filled out self-ratings of social behaviour and peer sociometric nominations. Teachers assessed children's social behaviour, rating the same child-generated prosocial behaviours. Popular children were rated as significantly more prosocial than all other sociometric groups and rejected children were rated as significantly less prosocial than all other groups. The highest correlation was found between teacher and peer reports of prosocial behaviour. Self-ratings and peer-ratings of prosocial behaviour were significantly related, as were self-ratings and teacherratings of prosocial behaviour. Implications of research findings are discussed.  相似文献
