长期股权投资收益确认问题的探讨

长期股权投资收益的核算方法有成本法和权益法两种。在权益法下应根据投资比例和被投资企业的盈利确认投资收益，但是，这样处理不符合资产的定义和会计准则的基本要求，也是通货膨胀产生的重要原因。因此，在反映双方内在经济利益关系的基础上，有必要按收付实现制核算投资收益。

Investigating academic dishonesty among Chinese undergraduate students: does gender matter?

The high rate of academic dishonesty reported among Chinese college students has created challenges for practitioners in both domestic and Western universities. Following two contrasting yet complementary scholarly approaches, this study explored the relative importance of predictors indicative of students’ intention to cheat (moral attitude, subjective norm and penalty enforcement) and of their educational preparedness for academic integrity (integrity engagement) in explaining academic dishonesty, with an emphasis on gender differences. We administered a questionnaire survey to a sample of 2009 Chinese undergraduate students. The results indicated that moral attitude and integrity engagement were the major predictors, that subjective norm accounted for marginal variations of academic dishonesty, and that the influence of penalty enforcement was insignificant. Some gender differences on both the mean score and effect levels of the four predictors were revealed. The effects of grade, year and area of study on academic dishonesty (and particularly their joint effects with gender) were noteworthy. These findings are discussed relative to the results of prior studies and the Chinese context.     

建设现代编辑心理学刍议

现代编辑心理学是把普通心理学、现代心理学的有关理论与编辑工作的具体实践结合起来,主要探讨编辑活动中认识主体各自的心理特征、心理现象、心理机制及其他们之间相互的心理感应规律与心理活动规律的一门学科.它是新兴的边缘交叉学科,也是一门应用学科;它的特点是具有交叉性、独特性、创造性、实践性、探索性.研究的原则是客观性、反映论、发展性、系统性;研究的方法是观察法、实验法、心理测验法、调查研究法;研究的意义是有助于推动编辑学和心理学自身的发展,有助于提高编辑队伍的素质,培养编辑健全的人格.

用概率树图法求解事件发生的概率

求事件发生的概率时,首先按事件先后发生的顺序画出概率树图,在概率树图上注明各个事件发生的概率,然后沿事件的终点重返始点,再利用概率的乘法公式和概率的可加性,即可求得事件发生的概率.     

The Use and Misuse of Standardized Testing: A Whiteheadian Point of View

First an overview is given about the actual national and international situation concerning standardized testing. Then two major reasons are presented why accountability systems based on standardized testing have become so widespread: (a) the missing validity and reliability of teachers’ assessment of students’ achievement, and (b) the important role standardized testing plays for out-put management in educational systems.On the basis of these considerations Alfred North Whitehead’s critical remarks on external standardized testing are presented. Whitehead’s main point is that external standardized testing limits the freedom of teachers to adapt to the complex, situation specific circumstances in order to obtain a maximum of the creative learning process for students who are conceived as specialists. Instead external testings lead to “teaching to the test.” As a consequence, the attitude of creative, adventurous exploration is undermined and substituted by simple pattern recognition, narrow visions, and even boredom. Finally, the question is raised whether there is any possibility of developing a measurement tool which on the one side meets scientific test criteria, and on the other side is still flexible enough to do justice to needs of individual schools – which according to Whitehead are the essential educational unit – and not vice versa, as it is the case at present with external standardized testing. That such a flexible approach to evaluation is possible is demonstrated by the presentation of the basic ideas of the MSS (Module Approach to Self-Evaluation of School Development Projects) which has been developed and examined in ten schools by the author and his collaborators.
