劳动力流动与地区经济增长差距研究

文章借鉴巴罗、萨拉伊马丁和德拉柯兹有关带移民的经济增长模型,并在此基础上对劳动力流动与地区内、地区间经济增长差距的内在关系进行理论推导发现,劳动力流动加快了中国发达地区经济增长收敛速度,而降低了欠发达地区的经济增长收敛速度。通过考察地区间因劳动力流动而导致的人力资本存量变动及相应的潜在产出外溢与滴漏效应冲击,印证了劳动力流动拉大地区差距的结论。作者还估算了近年来劳动力省际流动状况,并进行实证研究。     

Evaluations of FDR-controlling procedures in multiple hypothesis testing

Many exploratory experiments such as DNA microarray or brain imaging require simultaneously comparisons of hundreds or thousands of hypotheses. Under such a setting, using the false discovery rate (FDR) as an overall Type I error is recommended (Benjamini and Hochberg in J. R. Stat. Soc. B 57:289–300, 1995). Many FDR controlling procedures have been proposed. However, when evaluating the performance of FDR-controlling procedures, researchers are often focused on the ability of procedures to control the FDR and to achieve high power. Meanwhile, under the multiple hypotheses, it may be also likely to commit a false non-discovery or fail to claim a true non-significance. In addition, various experimental parameters such as the number of hypotheses, the proportion of the number of true null hypotheses to the number of hypotheses, the samples size and the correlation structure may affect the performance of FDR controlling procedures. The purpose of this paper is to illustrate the performance of some existing FDR controlling procedures in terms of four indices, i.e., the FDR, the false non-discovery rate, the sensitivity and the specificity. Analytical results of these indices for the FDR controlling procedures are derived. Simulations are also performed to evaluate the performance of controlling procedures in terms of these indices under various experimental parameters. The result can be used to summarize as a guidance for practitioners to properly choose a FDR controlling procedure.     

时变空间权重矩阵面板数据模型稳健LM检验有效性研究

空间权重矩阵是描述个体间空间关系的重要工具,通常基于个体间的地理距离构造不随时间而改变的空间权重矩阵。然而,当个体间的空间关系源自经济/社会/贸易距离或人口流动性/气候等特征时,空间权重矩阵本质上可能将随时间而改变。由此,本研究提出时变空间权重矩阵面板数据模型的稳健LM检验。大量Monte Carlo模拟结果显示：从检验水平和功效角度来看,基于误设的非时变空间权重矩阵的稳健LM检验存在较大偏差,但是基于时变空间权重矩阵的稳健LM检验能够有效地识别面板数据中的空间关系类型。尤其是,在时间较长和个体较多等情况下,时变空间权重矩阵的稳健LM检验功效更高。     

Using a genetic algorithm-based RAROC model for the performance and persistence of the funds

Assisting fund investors in making better investment decisions when faced with market climate change is an important subject. For this purpose, we adopt a genetic algorithm (GA) to search for an optimal decay factor for an exponential weighted moving average model, which is used to calculate the value at risk combined with risk-adjusted return on capital (RAROC). We then propose a GA-based RAROC model. Next, using the model we find the optimal decay factor and investigate the performance and persistence of 31 Taiwanese open-end equity mutual funds over the period from November 2006 to October 2009, divided into three periods: November 2006–October 2007, November 2007–October 2008, and November 2008–October 2009, which includes the global financial crisis. We find that for three periods, the optimal decay factors are 0.999, 0.951, and 0.990, respectively. The rankings of funds between bull and bear markets are quite different. Moreover, the proposed model improves performance persistence. That is, a fund's past performance will continue into the future.

城市中小学生家庭心理健康教育调查研究——以广州市为例

本研究采用自编问卷,从家长具备的心理健康教育意识、心理健康教育知识以及心理健康教育方法三个层面对广州市中小学生家庭心理健康教育的现状进行了调查,结果表明：（1）大多数家长（84．8％）在对待孩子的心理问题上态度是恰当的,但仍有部分家长,没有有意识地对孩子进行过心理健康教育;（2）家长的心理健康教育知识水平参差不齐,大部分家长（79．6％）对心理健康教育知识的了解比较肤浅;（3）家长的职业、受教育程度、对心理教育的看法、心理健康知识水平都是影响心理健康教育方式的重要因素。针对研究结果,文章从树立心理健康教育意识、建立家校协调的心理健康教育网络、提高家长的心理健康教育水平等方面提出了建设性的意见。

论新中国民族政策的合法性

新中国民族政策的合法性主要来源于意识形态、法理和绩效基础。当前中国民族政策的合法性正面临着新的挑战,应从推进民族理论创新、加强马克思主义民族观教育、完善民族政策、将民族政策提升为民族法规等方面入手,巩固民族政策的合法性基础,使民族政策赢得社会的共同认可和广泛支持。     

《兔侠传奇》:民族动画新标杆

讲故事一直是中国动画的弱项,解放前万籁鸣学习美国动画;建国初期中国动画学习苏联动画;在红色经典动画之后,我们大量学习日本动画,数量＂大跃进＂而质量＂滥竽充数＂,反而杀伤了中国动画。《兔侠传奇》巧妙设置悬念、复制类似《宝莲灯》这样的倡导诚信、惩恶扬善的故事模式,并借助名人、明星效应以及民族特色鲜明的场景设置,成为了当前民族动画产业化发展的标杆。
