基于受众需求视角的地方高校网站建设研究

高校网站是大学最重要的媒体和展示平台,是教师、学生、企业、媒体了解高校的主要媒介。长期以来,地方高校网站以高校为中心,忽视受众的需求,导致大多数高校网站出现设计水平低、内容单一、缺乏人文关怀的现状。要改变当前现状,可以从受众需求的角度入手,借鉴营销4C的理念,真正发挥高校网站的作用。

骆宾基建国后小说创作的心路历程

骆宾基建国后的小说，在创作方法上仍选择了现实主义，而在文化观念上则选择了政治倾向性。这一文学艺术观的确定，经历了空虚、疑虑、困惑、寻求等痛苦的情感纠葛和理性思考。骆宾基在走过了一段艰难的心路历程之后。又以极大的热情创作了许多适应时代要求的文学作品。他建国后的创作成就虽难以与建国前相比，但却能看出一个跨时代作家坚韧顽强的创作精神和对党和民族忠实自觉的使命感。政治阐释成为骆宾基建国后小说创作的现实主义特征。     

(M,S)-optimal row-column designs

Row-column designs may be considered to have two blocking schemes, namely the treatments by rows and treatments by columns component block designs. The (M,S)-optimality criterion is applied to row-column designs, and che connection between the (M,S)-optimal design and its component block designs is demonstrated.     

Semiparametric median residual life model and inference

For randomly censored data, the authors propose a general class of semiparametric median residual life models. They incorporate covariates in a generalized linear form while leaving the baseline median residual life function completely unspecified. Despite the non‐identifiability of the survival function for a given median residual life function, a simple and natural procedure is proposed to estimate the regression parameters and the baseline median residual life function. The authors derive the asymptotic properties for the estimators, and demonstrate the numerical performance of the proposed method through simulation studies. The median residual life model can be easily generalized to model other quantiles, and the estimation method can also be applied to the mean residual life model.

Citizenship and Labor Market Position: Turkish Immigrants in Germany and the Netherlands1

The relation between citizenship and labor market position is complex. Besides a causal impact from citizenship towards labor market position, several selection mechanisms may cause particular immigrants to choose for naturalization. We investigate the empirical relation on the basis of German and Dutch survey data. For the Netherlands we find a positive relation between citizenship and labor market position, while for Germany we find mixed results as citizenship is negatively related to tenured employment. The contrasting results may be explained by institutional differences. In Germany, economic self-reliance is more strictly required for naturalization than in the Netherlands. This may lead to a stronger incentive to naturalize for workers with a temporary contract in Germany.     

College Student Behavior: A Ten-Year Look

Abstract

Lester and Perez¹ have suggested that student behavior can be usefully construed in terms of a traditional-hedonic, implicit value system. They demonstrated that drug use and sexual activity provide simple behavioral anchors for this dimension, and observed an increasingly hedonic orientation among students. Ten years after their initial study, the student population at the same institution was again sampled using an anonymous questionnaire. The 1980 sample included 208 subjects, and these were compared with 688 subjects who responded to the 1970 survey. This comparison was supplemented by an intensive week-long study of 53 students within one campus living unit.

Significant increases in pre-college sexual activity were noted for both men and women. Marijuana use in high school also increased for both men and women during this period, while alcohol use increased only among women. Previously observed differences between male and female pre-college sexual activity and marijuana use had largely disappeared by 1980. Significant increases in sexual activity while in college were found for women but not for men. For men, overall marijuana and alcohol use in college did not change during the study period, but there was an increase in the frequent use of these drugs. Increases in all categories of marijuana use were noted among women, along with overall increases in their alcohol use. The significant differences between male and female marijuana use noted in the 1970 study were absent in 1980. The intensive week-long study revealed that alcohol use was part of the daily lives of one-third to two-thirds of the students sampled, although they reported interpersonal conflicts, absences from class, accidents, and injuries among the consequences of their drinking. A significant inverse relationship between sleep and alcohol use was observed among women, but not among men.

These data suggest that student behavior has become increasingly hedonic during the past ten years, with women in particular closing the gap which previously differentiated their behavior from that of their male peers. Institutions of higher learning must take these changes into account in the planning of academic programs, residential life, and health services.     

Simple inference in multinomial and ordered logit

This paper provides some simple methods of interpreting the coefficients in multinomial logit and ordered logit models. These methods are summarized in Propositions concerning the magnitudes, signs, and patterns of partial derivatives of the outcome probabilities with respect to the exogenousvariables. The paper also provides an empirical example illustrating the use of these Propositions.     

Graphical contributions to the χ2statistic for two-way contingency tables

A graphical procedure for studying the cell contributions to the chi-square statistic for R×C contingency tables is presented. Several examples are included to illustrate how one might use this graphical procedure on large tables.
