大学生就业问题近年来成为社会各界关注的热点问题,少数民族大学毕业生的就业问题因其既具有共性,又带有特性,更应成为关注的焦点。本文基于对西南民族大学少数民族毕业生就业问题的调研,发现当前成都地区高校少数民族毕业生一定程度存在热衷大城市就业,沟通能力相对不足,从事工作与所学专业不对口,易受到不公对待等就业问题。究其原因,我们认为与少数民族大学毕业生的传统择业观、汉语水平、学校的专业设置以及用人单位的不当认识有关。为此,本文提出政府应加大对少数民族大学毕业生就业的关注程度;学校应提高少数民族大学生的综合素质;社会应创造公平公正的就业环境;少数民族大学生应提升自身能力、转变择业观念等相关对策建议。 相似文献

This study investigated the relationships between types of activity and quality of life (QOL) for older men and women at different ages. Based on cross-sectional data that included 220 community-dwelling elderly persons aged 65 and older in southern Taiwan, the results showed that the participation rates in many activities declined with age for both genders. Social activity and solitary leisure activity were significantly associated with QOL for old-old men, but not for young-old men. Only social activity was significantly associated with QOL for young-old women, but there was no significant association between any activity and QOL for old-old women. 相似文献

波兰尼提出了缄默知识,为人类对知识的认识提供了新的视角,引起了人们的广泛关注和相关的深入研究。本文从谱系学的角度,在这种分类方法的基础上提出"缄口知识",并对教师"缄口知识"与缄默知识、教育潜规则、教育习俗进行比较,从认识论、微观政治学和价值论的视角,分析了教师"缄口知识"存在的合理性,并提出研究教师"缄口知识"有利于认识教师个体知识、解释微观教育现象和推进教育改革发展。 相似文献

提高学生语文素养的方法之一是扩大学生的阅读量。指导学生群文阅读是扩大学生阅读量的重要途径。在指导学生群文阅读过程中,教师事实上要扮演多元化角色:他既是人文知识的储备者,也是教学活动的组织者;既是阅读指导的开拓者,也是学生阅读的欣赏者。 相似文献

This paper proves continuity of f-projections and the continuous dependence of the limit matrix of the iterative proportional fitting procedure (IPF procedure) on the given matrix as well as the given marginals under certain regularity constraints. For finite spaces, the concept of f-projections of finite measures on a compact and convex set is introduced and continuity of f-projections is proven. This result is applied to the IPF procedure. Given a nonnegative matrix as well as row and column marginals the IPF procedure generates a sequence of matrices, called the IPF sequence, by alternately fitting rows and columns to match their respective marginals. The procedure is equivalent to cyclic f-projections. If the IPF sequence converges, the application of the continuity of f-projections yields the continuous dependence of the limit matrix on the given matrix. By generalized convex programming and under some constraints, it is shown that the limit matrix of the IPF sequence continuously depends not only on the given matrix but also on the marginals. 相似文献

In the article, properties of the Bennett test and Miller test are analyzed. Assuming that the sample size is the same for each sample and considering the null hypothesis that the coefficients of variation for k populations are equal against the hypothesis that k ? 1 coefficients of variation are the same but differ from the coefficient of variation for the kth population, the empirical significance level and the power of the test are studied. Moreover, the dependence of the test statistic and the power of the test on the ratio of coefficients of variation are considered. The analyses are performed on simulated data. 相似文献

This article proposes a CV chart by using the variable sample size and sampling interval (VSSI) feature to improve the performance of the basic CV chart, for detecting small and moderate shifts in the CV. The proposed VSSI CV chart is designed by allowing the sample size and the sampling interval to vary. The VSSI CV chart's statistical performance is measured by using the average time to signal (ATS) and expected average time to signal (EATS) criteria and is compared with that of existing CV charts. The Markov chain approach is employed in the design of the chart. 相似文献

In this article, based on generalized order statistics from a family of proportional hazard rate model, we use a statistical test to generate a class of preliminary test estimators and shrinkage preliminary test estimators for the proportionality parameter. These estimators are compared under Pitman measure of closeness (PMC) as well as MSE criteria. Although the PMC suffers from non transitivity, in the first class of estimators, it has the transitivity property and we obtain the Pitman-closest estimator. Analytical and graphical methods are used to show the range of parameter in which preliminary test and shrinkage preliminary test estimators perform better than their competitor estimators. Results reveal that when the prior information is not too far from its real value, the proposed estimators are superior based on both mentioned criteria. 相似文献
