国内外广告产业统计范围的比较

广告产业统计为广告产业发展的基础性研究课题,同时是政府进行广告产业的财政统计的依据与标准以及实现国际相同产业发展对照的基本标准.我国现行的广告产业统计标准多年来未经调整修正,不能真实反映产业发展实际.文章通过综述国内外相关学术研究,并结合我国现行的《广告业统计报表制度(2012)》、《国民经济行业分类(GB/T4754-2011)》、联合国颁布的《所有经济活动之国际标准行业分类(修订4版)》与《北美产业分类体系(2012)》当中广告产业的统计分类与统计范围,总结我国现行的广告产业统计分类标准存在的主要问题,即产业界定、定位与广告产业现实发展偏离;产业分类方式滞后;产业统计范围狭窄且有重合之处.     

对山西省高等教育公平问题的思考

随着我国高等教育大众化进程的加快,山西省高等教育在入学机会、教育过程、教育结果等方面都存在着不公平问题。为此,应完善教育政策、建立公平机制、改革收费制度、提高培养质量、加强就业指导体系建设、推进就业机会平等,尽量减少不公平现象。     

维吾尔族大学生的民族刻板印象

本研究采用问卷调查法,对维吾尔族大学生的民族刻板印象进行了调查。被试对汉族人和泉古族人形成的刻板印象以正面与中性的印象为主。被试认为,汉族人最主要的10项特征是爱吃菜、勤劳、团结、小气、自私、爱国、朴实、节俭、爱喝酒和追求享受;蒙古族人最主要的10项特征是勇敢、凝聚力强、游牧、爱喝酒、野蛮、高大强壮、擅长摔跤、好客、好斗和能歌善舞。     

Perceived social standing among Asian immigrants in the US: Do reasons for immigration matter?

We investigate the association between a subjective measure of social status and the reasons for immigration among Asian immigrants in the US. We use data from the National Latino and Asian American Study to test several hypotheses about this association. Our analyses show the positive effect on perceived social standing of migrating for better education, the negative effect of migrating to seek employment, and the negative impact of refugee status. Migrating for family reunification can be associated with various circumstances, which lead to differing outcomes. The results suggest that the notion that immigrants arrive in the US with limited resources and few skills and move slowly up the socioeconomic ladder must be reassessed in light of the complex social context and factors such as ethnicity, gender, divergent immigration paths, and a range of associated circumstances.     

经济转型与增长的持续性:来自中国的经验

通过发挥要素组合优势和承接世界产业转移.中国经济保持了30年高增长.但与此同时,也累积了能源、资源和环境压力,而且使收入分配不利于劳动力,进而形成通货膨胀与通货紧缩的交替反复.随着"刘易斯转折点"的逼近和国际规则的新变化,经济格局将出现整体性调整,这可能推动中国经济发展方式的转变,也可能进入均衡陷阱.实现发展方式转变的关键是发展现代产业体系和调整收入分配结构,这需要包括企业、市场和政府在内的全面经济转型.     

Estimation in capture–recapture models when covariates are subject to measurement errors and missing data

For capture–recapture models when covariates are subject to measurement errors and missing data, a set of estimating equations is constructed to estimate population size and relevant parameters. These estimating equations can be solved by an algorithm similar to the EM algorithm. The proposed method is also applicable to the situation when covariates with no measurement errors have missing data. Simulation studies are used to assess the performance of the proposed estimator. The estimator is also applied to a capture–recapture experiment on the bird species Prinia flaviventris in Hong Kong.

论后现代语境中文学的现实性

在后现代仿真语境中,看到传统的文学现实性理论之弊端是必要的,认清它的形而上学依据也是至关重要的.然而,理论之用应该只在于其方法论意义,它能够帮助我们从各种角度去理解文学,理解文学所展示的无边的生活与复杂的人性.让理论走下神坛,让文学亲近多彩的生活世界,同时,还要为文学向我们展示可能的世界留有一方领地,这是每一位文学研究者的责任所在.     

大庆文化形态之分析

大庆市是一个多民族地区,其文化主要有三种形态:一是土著文化,即草原文化;二是移民文化,即农耕文化;三是工业文化,即近现代文化.在和谐社会建设中,大庆市在发挥工业文化主导作用的同时,要重视农耕文化,尤其要研究和重视草原文化的民族特性,从蒙古族所处的地理环境、资源条件、历史文化、民族特点等实际出发,依托和借助于地域的和民族的载体与形式,使草原文化不仅在传承中发展,也能在与农耕文化、工业文化的交融中更新.     

Estimation of variance in bivariate normal distribution after the preliminary test of homogeneity

A preliminary test estimator of variance in the bivariate normal distribution is proposed after the Pitman–Morgan test of homogeneity of two variances. The bias and mean square error of the estimator are derived. The relative efficiency (RE) of the preliminary test estimator is studied. Computations and 3D graphs of RE for different parameters are analyzed. In order to get the maximum RE, recommendations of the significance level for the preliminary test are given for various sample sizes by using the max–min criterion.     

An integral formula for the distribution of self-normalized Gaussian random samples

Given i.i.d. Gaussian random variables and after standardizing the sample by subtracting the sample mean and dividing it by the sample deviation, we obtain an integral formula for the distribution of these self-normalized variables. Using geometrical arguments, we obtain the distribution of each and the joint distribution of two of them. These formulas can be used to calculate the expected value of the particular type of Cramér von Mises statistic to test normality.
