大学公共艺术课程的异化现象及对策

目前大学公共艺术课程存在技能化与专业化、非艺术化、非课程化、功利化等异化现象。要加强公共艺术课程建设,就应树立主体课程观、素质发展课程观和体验课程观,构建公共艺术课程体系,实现大学公共艺术课程“角色管理”。     

Neighborhood influences on adolescent cigarette and alcohol use: mediating effects through parent and peer behaviors

The influence of neighborhoods on adolescent behaviors has received increasing research attention. In the present study, we use structural equation models to specify pathways from neighborhoods to adolescent cigarette and alcohol use through parental closeness, parental monitoring, parent substance use, and peer substance use. We use a national sample with 959 adolescents 12 to 14 years of age whose residential addresses were matched with 1990 Census tracts to provide neighborhood characteristics. We found that for adolescent cigarette use low socioeconomic status (SES) neighborhoods were associated with increased parental monitoring, which was further associated with decreased adolescent cigarette use. For adolescent alcohol use, high SES neighborhoods were associated with increased parent drinking, which was further associated with increased adolescent alcohol use. Low SES neighborhoods were associated with increased parental monitoring and increased peer drinking, which were in turn associated with decreased and increased adolescent alcohol use, respectively.     

宽严相济语境下未成年人累犯制度释疑及完善

理论及司法实务界对"未成年人犯罪不适用累犯"应如何认定仍存在争议。在宽严相济刑事政策背景下,应对"不满十八周岁的人犯罪不构成累犯"作缩小解释,同时应在刑事责任年龄外根据不同的犯罪类型对未成年人是否适用累犯作进一步区分,以更好地预防未成年人犯罪。     

On the decomposition of X2 for two-way contingency tables

When samples are taken independently from I populations and the subjects classified into J categories, can the Pearson's chisquare statistic X² testing the homogeneity model on the resulting I×J two-way table be decomposed into components familiar in the analysis of variance? Will the X² testing the homogeneity model on tables derived by collapsing columns in the spirit of orthogonal comparisons in factorial experiments be asymptotically independent? The answers to both questions are generally negative. This paper gives a theoretical justification.

An empirical study on technical analysis: GARCH (1, 1) model

One of the deficits of the common Bollinger band is that it fails to consider the fat tails/leptokurtosis often exists in financial time series. An adjusted Bollinger band generated by rolling GARCH regression method is proposed in this study. The performance of the adjusted Bollinger band strategy on EUR, GBP, JPY, and AUD vs. USD foreign exchange trading is evaluated. Results show that in general, the adjusted Bollinger band performs better than the traditional one in terms of success ratios, net successes, and profit. In addition, no matter there is transaction cost or not, only adjusted Bollinger strategies are recommended for investors. Adjusted Bollinger band strategies with MA 5 or 10 are recommended for EUR, GBP, and JPY. Adjusted Bollinger strategy with MA 20 is the recommended strategies for AUD.     

基础设施建设PPP项目关键绩效指标识别研究

中国城市公用事业的民营化改革是当前中国的重要政策,PPP模式被广泛应用到中国的各类基础设施建设中。在实际的工作中政府却缺乏行之有效的关键绩效指标体系(Key Performance Indicators,KPI),不能够为项目的绩效考核提供可以依据的标准,最终致使项目的政府监管缺位,绩效无法跟踪,项目产出受到影响,社会公众的福利难以得到保障。文章针对此问题,在以往研究和问卷调查的基础上,运用结构方程模型对48个绩效指标进行进一步分析,为政府监管PPP项目识别出41个KPI,并分析了指标分组之间的关系,对中国的基础设施建设和运营提供了保障,为PPP项目绩效提高提供了可供参考的重要依据。     

脱硫废渣改良白城碱化土壤的pH变化分析

本文通过对白城市盐碱地现状的研究,以电厂脱硫废弃物为主要原料,在白城市洮北区德顺蒙古族乡英格尔屯盐碱地治理实验基地进行了改良试验研究,改良后土壤的pH值明显降低,土壤空隙增多,土壤通透性提高,土壤板结明显改善,作物产量大幅度增加.     

社会分层对中国经济发展的影响

生态政治:权威主义,还是民主主义?

生态政治在其发展过程中长期被指责带有权威主义的倾向。这种指责来自于两条路径:一条是环境运动早期消极思想所致的权威主义表现;另一条是近些年来对绿色结果与民主程序之间关系的质疑。指责生态政治具有权威主义倾向的第一来源已经退出了历史舞台,而且,这种权威主义表现和观念在生态政治中的影响极为有限。后一条质疑是问题的关键。借助于对民主权利的讨论,辨识出民主需要绿色结果;通过对自治原则的讨论,辨析出绿色结果需要民主,从而在生态政治与民主之间建立起一种可辨性的稳固联系,明确二者的相融性,将生态政治从权威主义阴影的笼罩中解放出来。
