课堂质量评价对高校教师教学行为的影响研究

课堂质量决定着高校人才培养的质量。对课堂质量进行科学评价,可以引导教师行为不断改进,进而促进课堂质量的持续提升。为此,该文在对课堂质量及其评价理论、教学行为等基本概念进行阐释的基础上,结合当前高校所开展的课堂质量评价实践,从评价主体、评价指标和评价方法三个方面分析了课堂质量评价对高校教师教学行为的影响作用。     

Application of the OCRA Method in the sugar cane harvest and its repercussion on the workers' health. Preliminary study

In Brazil the sugar ethanol industry has had strong growth in the last 10 years, sometimes due to the growing sugar exportation, sometimes due to the alcohol production for automobile fuel and for exportation. Despite the growing mechanization of the raw material harvest (sugar cane), the manual work still persists. The development of this article was based in the application of the OCRA Method in the sugar cane harvesting process, to evaluate the risks to the upper limbs by repetitive movements and epidemiologically prove the ratio risk x harm to the heath of the workers, as well as the probability of developing improvements in the working conditions. The analysis process consists of studying the work organization, the risks to the health of the worker and the distribution of the recovery periods during the working day.     

Analysis of individual- and time-specific covariate effects on survival of Serinus serinus in north-eastern Spain

We developed models for the analysis of recapture data for 2678 serins ( Serinus serinus ) ringed in north-eastern Spain since 1985. We investigated several time- and individual-specific factors as potential predictors of overall mortality and dispersal patterns, and of gender and age differences in these patterns. Time-specific covariates included minimum daily temperature, days below freezing, and abundance of a strong competitor, siskins ( Carduelis spinus ) during winter, and maximum temperature and rainfall during summer. Individual covariates included body mass (i.e. body condition), and wing length (i.e. flying ability), and interactions between body mass and environmental factors. We found little support of a predictive relationship between environmental factors and survival, but good evidence of relationships between body mass and survival, especially for juveniles. Juvenile survival appears to vary in a curvilinear manner with increasing mass, suggesting that there may exist an optimal mass beyond which increases are detrimental. The mass-survival relationship does seem to be influenced by at least one environmental factor, namely the abundance of wintering siskins. When siskins are abundant, increases in body mass appear to relate strongly to increasing survival. When siskin numbers are average or low the relationship is largely reversed, suggesting that the presence of strong competition mitigates the otherwise largely negative aspects of greater body mass. Wing length in juveniles also appears to be related positively to survival, perhaps largely due to the influence of a few unusually large juveniles with adult-like survival. Further work is needed to test these relationships, ideally under experimentation.     

东北亚区域经济合作的现状、困难及前景

区域经济一体化浪潮下,加强东北亚的区域经济合作,促进东北亚地区的经济发展已成为一个亟待解决的问题。当前,建立真正意义上的东北亚经济合作区域的条件尚不具备,因此,应以建立中、日、韩自由贸易区作为区域经济合作的突破点,利用振兴东北经济战略的契机,打开东北亚地区区域经济合作的新局面。

“I Did Not Get that Job Because of a Black Man...”: The Story Lines and Testimonies of Color-Blind Racism

In this paper we discuss the dominant racial stories that accompany color-blind racism, the dominant post–civil rights racial ideology, and asses their ideological role. Using interview data from the 1997 Survey of College Students Social Attitudes and the 1998 Detroit Area Study, we document the prevalence of four story lines and two types of testimonies among whites. We also provide data on ideological dissidence among some whites (we label them racial progressives) and blacks. We show that although these stories, and the racial ideology they reinforce, have become dominant, neither goes uncontested.     

Political election on legal retirement age

In the context of the current debate surrounding the reform of pension systems, this paper analyzes the political economy of the legal retirement age. Using a life-cycle model in which individuals differ by age and by wage, we analyze the outcome of a majority voting process on the legal retirement age in a Pay-As-You-Go pension system. The results show that the older an individual is, the closer her optimal retirement age is to the status quo age. That is, the status quo retirement age acts as a magnet. Additionally, we find that the preferred legal retirement age of most of the working population increases when the pension system is more redistributive. We also observe a positive relationship between the preferred legal retirement age and the status quo age.     

论我国引咎辞职制

引咎辞职制度是我国干部人事制度改革的重要内容,是加强社会主义道德建设,加强党的执政能力建设以及缓和政府与人民之间的矛盾的制度保障。引咎辞职,有利于落实立党为公、执政为民的宗旨;有利于推行依法行政,建立责任政府;有利于转变领导干部的工作作风。国家需要发展,社会需要和谐。人民期待引咎辞职制更加完善,促使官员们真正做到“情为民所系,权为民所用,利为民所谋”,恪尽职守、竭尽心力为人民服务。
