Testing the monotonicity or convexity of a function using regression splines

Methods for smoothed isotonic or convex regression are useful in many applications. Sometimes the shape assumptions constitute a priori knowledge about the regression function, but often the shape is part of the research question. The authors propose tests for monotonicity and convexity using constrained and unconstrained regression splines. The tests have good large‐sample properties and the small‐sample behaviour is illustrated through simulations. Extensions to the partial linear model and the generalized regression model are presented. The Canadian Journal of Statistics 39: 89–107; 2011 © 2011 Statistical Society of Canada     

平等权的存在形态及其内涵

现代平等权已经从道德形态演进为权利形态,成为宪法上的一项基本人权,其本质是对每一个个体的平等人格的尊重。平等权具有明确的、独特的权利内涵,核心部分包括禁止歧视和反对特权。现实生活中我国的不平等现象屡见不鲜,需要从意识更新和制度建构两方面入手,重构平权社会。     

明月竹箫与华堂合弦--从中西传统绘画看中西艺术之不同

艺术是艺术家对客观世界的解读方式,艺术作品是艺术家心灵世界的外化.相同文化意识背景下的艺术家,其作品在审美形态上会呈现一种共性.这就为我们提供了比较中西艺术的可能.本文对中西传统绘画艺术从形神关系、空间表现、艺术手段三方面进行了实践上的比较和理论上的梳理,并对影响艺术实践的中西文化及哲学思想作了初步探讨.     

消费者安全认证食品多源信任融合模型研究——以有机食品为例

消费者信任是安全认证食品市场发展的基础与关键所在。文章以青岛市262个样本为例,分析了消费者对政府监管效果、生产商行为特征与声誉、认证方行为特与声誉等问题的态度与评价,并以此为基础研究了这些因素对消费者信任的影响。结果表明,消费者对政府、生产商与认证机构等主体行为的满意度评价总体较低;政府监管评价对消费者信任影响较为显著;生产商行为特征与声誉对消费者信任的影响反而高于认证机构。规范认证行业发展,加强监管力度,构建有效认证体系,增强消费者信任成为当前政策亟需解决的关键难题。

线形态艺术在现代平面广告设计中的解读

线形态艺术作为现代平面广告设计的视觉表现元素之一,已成为现代平面广告创意表达的基本视觉语汇。但由于设计师常常将线作为平面设计元素的形式去创造表现图形,而忽视了线形态本身的艺术魅力和情感表达,致使现代平面广告中的一些有关线的表述缺乏深层次文化性,本文试从现代平面广告设计向当代多元化艺术设计的转向中,以线形态本身的艺术形态魅力结合其实际应用来重新解读线形态艺术在现当代平面广告设计中的价值与涵义。     

Improving body image and sexual health behaviors among college women

ABSTRACT

Objective: To conduct a pilot test to determine if the Body Project, an eating disorder prevention program, was able to reduce risky sexual behaviors. Participants: Twenty college-age women ages 18–21 (in March, 2015) who endorsed both body image dissatisfaction and previous or current sexual activity. Methods: Participants were randomized to the Body Project or psychoeducational control group, and completed baseline, post-test, and 6-month follow-up measures assessing body image concerns, eating behaviors, and sexual behaviors and attitudes. Results: An intervention manipulation check demonstrated that body image variables were in expected directions, though were not significant by group. There was a significant interaction across group and time for “unanticipated sexual encounters,” which decreased in the Body Project group. Conclusions: This pilot study supports the feasibility of using an eating disorder prevention program to reduce other risky behaviors, specifically risky sexual behaviors.     

It's More Than an M‐shape: The Political Economy of Female Non‐Standard Workers in the Republic of Korea

This study examines the re‐entrance of female workers into the Korean labor market. We highlight that women in their 40s have the highest rate of employment among all female workers and that a large proportion of these women are entering into non‐standard employment. In approaching this question, we examine the political economy of this phenomenon by first discussing the demand side of the Korean labor market using the gendering of the varieties of capitalism argument and then the supply side with the work–life balance argument. When examining re‐entrance into the labor market, women with general skills with lower education and higher education both found it more feasible to re‐enter the labor market as non‐standard workers. While work–life balance is a prominent reason for women's choice of opting out of the labor market, work–life balance choice mattered less for women re‐entering the labor market as non‐standard workers in their 40s and 50s but instead firmly based skill formation mattered more. In addition, the retail service industry is suggested to absorb a large number of female workers with lower skill levels who would have had difficulties in re‐entering other male‐oriented companies.     

Differences in Emerging-Adult Women's Body Image and Sexuality Outcomes According to BMI and Dating Status

ABSTRACT. Emerging adulthood is a crucial time for the development of body image and sexuality concerns among women. We collected self-reported data from 184 women to determine possible differences according to body mass index (BMI) classification and dating status. Multivariate analyses of variance and follow-up univariate analyses of variance were conducted to determine differences in body image and sexuality outcomes according to both BMI (normal weight vs. overweight) and dating status (dating vs. not dating) as well as interaction effects of BMI and dating status. First, results indicated differences between normal-weight and overweight women for body satisfaction, body self-consciousness, and body image avoidance. Overweight women had lower satisfaction, higher self-consciousness, and more avoidance. Differences were also found between women who were dating and those who were not dating for body satisfaction and self-consciousness: Women not dating had lower satisfaction and higher self-consciousness. Second, whereas results indicated that women of varying BMIs did not differ on sexuality outcomes, differences were found according to dating status for sexual attitudes, esteem, and self-schema, such that women not dating had more conservative sexual attitudes, less sexual esteem, and lower self-schemas. No significant interaction effects were found.
