端木蕻良土地情结的心理透视

端木蕻良是东北作家群的重要成员,其作品中凝聚着对故乡土地的深沉而强烈的爱,有着极强的“土地情结”。端木蕻良的“土地情结”缘于他深刻的人生体验。本文试图从端木蕻良的忧郁与孤独的童年经验以及渴望回归土地的归依体验透示他“土地情结”的审美心理。     

An interactional model of questions as therapeutic interventions

We dedicate this article to the memory of Steve de Shazer, who was the University's External Examiner for the doctoral dissertation on which this article is based. His comments were both generous and influential, as they were on many other occasions. We would also like to thank Ron Chenail (as Editor of JMFT ) and Dora Fried Schnitman (as Editor of Sistemas Familiares) for coordinating the simultaneous review and publication of this article in English and Spanish.     

A stochastic Newton-Raphson method

A stochastic approximation procedure of the Robbins-Monro type is considered. The original idea behind the Newton-Raphson method is used as follows. Given n approximations X₁,…, X_n with observations Y₁,…, Y_n, a least squares line is fitted to the points (X_m, Y_m),…, (X_n, Y_n) where m<n may depend on n. The (n+1)st approximation is taken to be the intersection of the least squares line with y=0. A variation of the resulting process is studied. It is shown that this process yields a strongly consistent sequence of estimates which is asymptotically normal with minimal asymptotic variance.     

时间知觉的脑机制研究

当前时间知觉的脑机制的研究结果出现了定位论和非定位论的研究趋向。支持定位论的证据主要集中在小脑高级功能区运动计时特异化作用及基底神经节分泌的多巴胺对时间知觉的作用;支持非定位论的证据主要集中在脑损伤、脑成像研究中关于多个脑区整合作用机制以及多种神经递质在计时中的作用。上述两种趋向是基于时距长短不同所致,比如对秒以下计时加工的部位在小脑高级功能区,而加工1秒及以上的时距则涉及多个脑区及神经递质的整合作用。时间知觉之脑机制研究正方兴未艾。     

公司治理结构中的代理成本与审计独立性的相关性研究

本文从"提高审计独立性对代理成本的影响"和"代理成本的高低对审计独立性的影响"两个角度,对代理成本与审计独立性的相关性进行了理论分析,认为代理成本与审计独立性具有正相关性,并将这一结论作为研究假设,提出了建立数学模型对两者的相关性进行实证研究的思路。文章认为,要提高审计独立性将会导致公司代理成本的相应提高,反之,代理成本越高,被审单位从其自身利益出发,必然要提高审计独立性。     

大学生乐观品质培养的实验研究

在对大学生乐观品质调查的基础上,设计了实验组、控制组和实验干预项目,并对实验组进行了解释型乐观的实验干预。实验结果表明,经过干预的实验组学生的解释型乐观水平显著高于控制组,此实验说明气质型乐观可以通过解释型乐观的干预模式得到培养。     

农村骨干教师流失问题研究——基于公平理论的探讨

农村骨干教师流失问题是我国农村教师队伍建设中面临的一大难题,结合农村骨干教师流失现状及笔者的一项调查证实了农村骨干教师流失的严重性,从公平理论的视角分析了农村骨干教师流失的内在心理行为及外在诱因,提出要从宏观政策与微观管理两方面着手,切实解决农村骨干教师流失问题。
