Causality and interdependence analysis in linear econometric models with an application to fertility

This paper is an applied analysis of the causal structure of linear multi-equational econometric models. Its aim is to identify the kind of relationships linking the endogenous variables of the model, distinguishing between causal links and feedback loops. The investigation is first carried out within a deterministic framework and then moves on to show how the results may change inside a more realistic stochastic context. The causal analysis is then specifically applied to a linear simultaneous equation model explaining fertility rates. The analysis is carried out by means of a specific RATS programming code designed to show the specific nature of the relationships within the model.     

Graphic Feedback,Performance Feedback,and Goal Setting Increased Staff Compliance With a Data Collection Task at a Large Residential Facility

Because of budgetary constraints, human service organizations frequently expect consultants to recommend methods to enhance staff performance that require little or no additional funding. The current study utilized a multiple baseline across settings design to evaluate and compare the effects of a single intervention and a packaged intervention including graphic feedback and goal setting on approximately 200 direct care staff as a group, to improve the data collection procedure at a residential treatment facility. The single intervention showed some improvement, whereas the packaged intervention yielded substantial improvements and was maintained.     

Keeping an Uphill Edge

Abstract

Several behaviors in a ski shop were identified as being deficient using Austin's Performance Diagnostic Checklist (2000) and Daniels and Daniels' PIC/NIC Analysis (2004). During a 4-week baseline, 7 cleaning behaviors were monitored and 5 were subsequently targeted in an intervention package using an ABC design. The intervention included: a task clarification session, a posted behavioral checklist, graphic feedback of the group's performance for the previous week, and daily task-specific feedback. Immediately after the checklist was posted, the frequency of employee cleaning behaviors increased 52%. Cleaning behaviors increased an additional 12% after the implementation of daily task-specific feedback. Results suggest the interventions generalized to the 2 cleaning behaviors not mentioned in the task-clarification session.

大学生职业生涯规划的反馈机制研究

大学生职业生涯规划应具备系统的反馈机制。按照发生期,反馈机制可以分为前反馈期、中反馈期与后反馈期;按照作用方向,分为正反馈和负反馈。反馈机制的设置原则应具有需求性、促进性、可操作性、动态性、结合性等。     

顾客积极反馈对一线员工努力意向的影响分析

尽管顾客反馈会在一定程度上影响一线服务员工的行为和态度，但有关这种逆向于传统营销研究视角的研究成果却很少。实际上，顾客的积极评价行为会增强一线服务员工的成就感，而顾客对服务员工的关系建设行为会增进一线员工感知的人际关系亲近程度，而员工的成就感和人际关系亲近程度的提高能进一步促进服务员工努力意向的提高。     

反馈交易规则与股票收益自相关实证分析

研究了反馈交易规则与上证综合指数日收益自相关之间的联系，样本取自上证指数１９９２年９月２９日至１９９７年９月３０日的日收益率数据。此外，文中采用ＧＡＲＣＨ（１，１）处理收益波动的异方差性，模型参数采用极大似然估计。实证模型还考虑了非同步交易引起的工序列相关以及反馈交易的非对称性。结果表明，除以往文献涉及的正序列相关外，正反馈交易将导致收益负的序列自相关，且相关系数绝对值随波动增大而增大，从而整个收益表现出随波动变化的序列相关。
