当代大学生作为社会中的重要群体,他们需要与外界的交往,处理关系,如何建立,发展,巩固这种关系,就要靠沟通来完成。在高校中,针对大学生的思想政治教育过程就是一个如何与他们沟通的过程。面对当下个性彰显,不断追求新事物的年轻群体,怎样把握沟通的要素和形式,它有哪些特点和功能,遵循什么样的原则和策略,以及新时期下师生沟通过程中出现的障碍和问题,正是本文要探讨的内容。  相似文献

1958年余江县在全国率先消灭血吸虫病,树立了全国“第一面血防红旗”,创造了世界血防奇迹。作为地域社会发生的重大历史事件,血防对余江县域政治演变产生了深刻影响。研究表明:高层领导对血防持续不断的关注和督促,为余江血防注入了源源不断的政治压力和政治变迁动力;历届县委、县政府都把血防作为“一把手工程”,视为“最大的政治”,使余江县域政治带有浓厚的“血防”色彩;县党政机构也发生相应变化,完成了血防领导机构的常规化和党政机构的血防化;余江是我国出台血防政令最多的县份之一,血防在余江县政治生活中占有极其重要的地位。血防塑造了余江地域政治特色,它使得余江县域政治带有明显的血防化特征。  相似文献

A random effects model for analyzing mixed longitudinal count and ordinal data is presented where the count response is inflated in two points (k and l) and an (k,l)-Inflated Power series distribution is used as its distribution. A full likelihood-based approach is used to obtain maximum likelihood estimates of parameters of the model. For data with non-ignorable missing values models with probit model for missing mechanism are used.The dependence between longitudinal sequences of responses and inflation parameters are investigated using a random effects approach. Also, to investigate the correlation between mixed ordinal and count responses of each individuals at each time, a shared random effect is used. In order to assess the performance of the model, a simulation study is performed for a case that the count response has (k,l)-Inflated Binomial distribution. Performance comparisons of count-ordinal random effect model, Zero-Inflated ordinal random effects model and (k,l)-Inflated ordinal random effects model are also given. The model is applied to a real social data set from the first two waves of the national longitudinal study of adolescent to adult health (Add Health study). In this data set, the joint responses are the number of days in a month that each individual smoked as the count response and the general health condition of each individual as the ordinal response. For the count response there is incidence of excess values of 0 and 30.  相似文献

Several procedures have been proposed for testing the hypothesis that all off-diagonal elements of the correlation matrix of a multivariate normal distribution are equal. If the hypothesis of equal correlation can be accepted, it is then of interest to estimate and perhaps test hypotheses for the common correlation. In this paper, two versions of five different test statistics are compared via simulation in terms of adequacy of the normal approximation, coverage probabilities of confidence intervals, control of Type I error, and power. The results indicate that two test statistics based on the average of the Fisher z-transforms of the sample correlations should be used in most cases. A statistic based on the sample eigenvalues also gives reasonable results for confidence intervals and lower-tailed tests.  相似文献

散打之力量是散打运动中除运动技术等要素外,非常重要的另一要素,散打之力量在运动中表现出两个方面的应用,即散打之局部力量和整体力量;散打之局部力量和整体力量在比赛中交替展现,正是由于散打之局部力量和整体力量的不停变换使用及不同情况下各种力量共同作用,运动员才能在比赛中赢得胜利。散打之局部力量与整体力量的科学应用与训练不仅塑造了练习者完美的运动身形,而且培养了个人不凡的运动气质,是一项完美的体育运动。  相似文献

Likelihood ratios (LRs) are used to characterize the efficiency of diagnostic tests. In this paper, we use the classical weighted least squares (CWLS) test procedure, which was originally used for testing the homogeneity of relative risks, for comparing the LRs of two or more binary diagnostic tests. We compare the performance of this method with the relative diagnostic likelihood ratio (rDLR) method and the diagnostic likelihood ratio regression (DLRReg) approach in terms of size and power, and we observe that the performances of CWLS and rDLR are the same when used to compare two diagnostic tests, while DLRReg method has higher type I error rates and powers. We also examine the performances of the CWLS and DLRReg methods for comparing three diagnostic tests in various sample size and prevalence combinations. On the basis of Monte Carlo simulations, we conclude that all of the tests are generally conservative and have low power, especially in settings of small sample size and low prevalence.  相似文献

如何界定爱国主义这一定义一直是学术界讨论的问题。《〈中共中央宣传部教育部关于进一步加强和改进高等学校思想政治理论课的意见〉实施方案》实施后,《思想道德修养与法律基础》教材不再运用列宁关于爱国主义的定义,而用了一个新的定义。科学地理解爱国主义不仅是爱国主义本质的内在要求,而且是理性爱国主义教育的前提。从“非人民群众”的爱国情感、“祖国”与“国家”的关系、爱国主义“理性”与“非理性”的关系三个角度进行探讨,认为社会主义国家应倡导理性爱国主义。  相似文献

遏制腐败,保持清正廉洁,是化解执政危险的必然要求。保持清正廉洁需要党员干部发挥主观能动性,加强自我修养,经得起来自权力、制度漏洞、利益、贪欲等多方面的考验。当然,由于人类谋求私利的本性,决定了靠人的自我修养并不能完全克服掌权者利用公权谋求私利的倾向,因此,防止腐败,还要加强制度规范的外部约束,完善制度体系建设,减少诱发腐败的“灰色地带”,做到“伸手必被捉”。  相似文献

According to Hannah Arendt, the concept of ‘political action’ is a fundamental component of the human condition because it encapsulates how the uniqueness of each human being intersects to create unpredictable political initiatives and effects. Recently, despite being one of the most daunting political challenges ever faced by humanity, there has been a noted collective action failure, or inaction, concerning the global threat of anthropogenic climate change. Why? This article seeks to explain this political inaction in a new way: by examining the metaphysical role that technology plays in disclosing the climate as a thinkable and global object. After applying the philosophy of Martin Heidegger to the complex mathematical general circulation models (GCMs) used by the Intergovernmental Panel on Climate Change (IPCC), this article details how the metaphysics underlying GCMs manifests the perceivable world by ‘enframing’ it, or by implicitly representing subjects, objects, and Nature itself, as a predictable, calculable, and orderable relation of static forces. When this metaphysical and mathematical uniformity constructs the climate as a calculable object that is globalised through the IPCC, it is ultimately found to be contradictory to the distinctness and unpredictability necessary for distinct human action to occur. Paradoxically, therefore, political action is argued to be metaphysically antithetical to the technologically enframed science, politics, and discourse, of global climate change itself. The importance of distinct and plural human places, when filtered through GCMs, becomes subsumed by the climate as a homogenous, calculative, and politically inactive, global object.  相似文献

The use of an international currency is not just a natural market phenomenon; it relies heavily on international political foundations. The historical lessons of the four major international currencies—the pound, dollar, euro and yen—show that a strong partner network and a favorable international institutional environment are the two major political foundations for the formation of a stable international currency. The rise of the renminbi, as a late starter looking to become a major international currency, depends not only on the requisite economic conditions but on governmental diplomacy aimed at attracting more monetary cooperation partners and creating international institutions that support its worldwide use. This strategy reinforces the political foundations for the rise of the renminbi. Building a network of partners supporting the renminbi as an international currency and creating a system of international monetary institutions are the real tests of the issuing country’s political leadership. This political leadership capacity has three dimensions: public trust founded on reputation building; a centripetal force driven by provision of benefits; and coercive force applied through sanctions. Comparatively speaking, the renminbi is still in the early stage of its ascent, so the development of its political infrastructure should concentrate mainly on gaining public trust through reputation-building and employing centripetal force involving provision of benefits.  相似文献
