基线评估法在社会工作实务过程中的应用

社会工作作为一种应用型较强的职业,它的工作过程是怎样的呢?其效果又如何呢?要做出对社会工作过程和效果的客观评价,就需要评估。那么具体采用什么样的评估方法呢?在社会工作实务过程中有一种比较有效、直观的方法叫基线评估法。本文试就基线测量法的含义、基线测量法的操作程序、基线评估法的优缺点等方面作探讨。     

社会工作实习教育模式构建的反思

提高学生的专业素养是社会工作实习的理想目标,但这种理想目标的实现是需要有一定的专业环境支持,当前中国并不具备这种环境。为了实现社会工作实习教育的理想目标,社会工作实习教育应该区分理想目标与手段目标的关系,在构建实习教育体系时,树立提高学生专业素养的理想目标和促进实习环境改善的手段目标。激发实习各方动力,满足各方需求,寻求多方共赢,是可以尝试的基本策略,而项目运作则是实现目标、落实策略的较好形式与载体。     

Semantic network representation of computer-mediated discussions: Conceptual facilitation form and knowledge acquisition

Prior research on computer-mediated discussions examined their effects on knowledge acquisition without considering the role of the discussion representation. In this study, we investigate and compare the effect of semantic network discussion representations on knowledge acquisition to that of the threaded representations featured in most traditional discussion forums. Furthermore, we identify, define and operationalize a new, i.e., conceptual facilitation (validation of the conceptual organization of the discussion), assessing its role in knowledge acquisition at different levels of restrictiveness. The empirical results of a field experiment indicate that semantic network discussion representations enable the acquisition of more complex and better-integrated knowledge structures than threaded discussion representations. Conceptual facilitation forms entailing different levels of restrictiveness are also found to play a significant role. As the level of conceptual facilitation restrictiveness decreases, knowledge acquisition improves. Our findings empirically demonstrate the importance of accounting for discussion representation as a contingency factor in explaining group discussion processes and outcomes. To practitioners, our study provides empirical evidence on the advantages of semantic networks over threaded representations as an alternative mode for computer-mediated discussion representations. We also suggest guidelines for the selection of appropriate conceptual facilitation for discussion forums intended for knowledge acquisition.     

Performance Evaluation of Enterprise Knowledge Management based on Multiple Attribute Group Decision Making

Given that the classical performance evaluation models can not deal with the group decision making problems since they simply average the index, we propose an enterprise knowledge management evaluation model based on multiple attribute group decision making (MAGDM). Find the differences between Ordered Weighted Averaging (OWA) and meth- ods for uncertain decision making. Also, analyze the multiple attribute group decision making process and implement the al. gorithm. Finally, apply the method on performance evaluation of four enterprises and make sensitivity analysis towards the evaluation results.     

合作研究、协调成本与知识增长

已有的文献在研究学术合作的影响因素时,大都忽略了协调成本的重要作用。本文详细地研究了知识生产中的协调成本问题,通过建立经济模型研究了学术研究最优的合作水平及其与协调成本的关系。在此基础上,通过建立动态的两部门模型研究了知识增长和经济增长的问题。研究表明:协调成本的增加会降低均衡的知识增长率和经济增长率;反之亦然。最后,本文为降低中国学术合作的协调成本提出了初步的政策建议。     

A股和H股净利润双重披露的实证分析（上)--实证研究的背景和结果

以同时发行A股和H股的公司2000、2001和2002年按中国大陆会计规范和香港会计实务准则或国际会计准则披露的会计数据中双重报告的净利润为样本,对差异的净利润进行统计分析,并对产生差异的不同准则项目的影响进行统计和比较分析,其结果表明:我国的会计准则在实质上与发达国家的会计准则已十分相近,按中国大陆会计准则和香港SSAP或IAS分别计算的净利润产生的差异不会对信息使用人产生大的误导.     

Shop Floor Control When Tacit Worker Knowledge is Important

We investigate a shop where the workers and supervisors have tacit knowledge of how to operate efficiently and where efficiency is important to providing capacity to meet demand. This tacit knowledge includes setup dependencies between products as well as which worker or machine is best suited for a particular product. We discuss a real‐world shop where this is the case. Management expects workers and supervisors to use their knowledge to schedule efficiently by monitoring their performance based on standards. The question that we explore is how management should control for due date performance in light of the discretion given to the workers and supervisors to sequence jobs on the basis of efficiency. We explore management control of due date performance through the use of order review and release (ORR) and management expediting. We find that although ORR is quite effective at reducing work‐in‐process (WIP) inventories, it may foster very late deliveries in a shop such as this. In fact, under such conditions, deftly executed expediting with no ORR at all can be far more effective at supporting all deliveries. Even improving ORR into a hybrid by actively updating path efficiencies (observed from supervisor/worker scheduling) did not support a change to this conclusion. Conversely, when conditions are created where tacit knowledge plays a reduced role or utilization is decreased, ORR delivers in a timely manner. The interaction between utilization, WIP levels, and worker knowledge all help dictate the appropriate control methodology.     

康德和孔子认识论之比较

中西方哲学的差异不在于哲学结论本身,而在于得出结论的方法和对结论的表述上。通过对康德的认识论命题“先天综合判断”与孔子的认识论命题“生而知之”、“学而知之”的比较可证明这一观点。从思维方式差异的对比上,也可为“中国的思想和科学开始领先于西方而最后又为西方所反超”这一学术公案寻找到一定的答案。
