Selective exposure to partisan media: Moderating factors in evaluations of the president

The conditions in which moderating factors – media trust, mediabias, and political ideology – increase or limit the approval ratings of a politician in a partisan media environment were investigated using data obtained from the 2010 Pew survey. The findings show that media trust and media bias intensify negative presidential evaluations among consumers of conservative news programs, whereas these factors do not influence presidential approval among consumers of liberal news programs. The findings also reveal that conservatives tend to choose to be exposed to news messages that are congenial to their ideological orientations, while liberals select a more balanced diet of news messages. This study proposes that moderating factors have different effects on conservative and liberal news consumers.     

用EMME/2软件来估计0-D矩阵的实用方法

本研究的目的是用精确的数据来获得更准确的0－D矩阵．这些数据诸如TCSO－D矩阵,观测的路段交通量和通过EMME／2获取的快速公共论车O－D矩阵。首先,建立每个收费站的一个有效区域,每个收费站的出入量被分配到有效区域中的小区,这一分配好的0－D矩阵再被分配给由所有收费站和它们的有效区域组成的网络．其次,我们校正区域0－D矩阵,排除TCSO－D矩阵,目的是反映现测到的交通量,而将快速公共汽车和分配的路段交通量作为额外的交通量．与实际交通量相比,用估算过的交通小区0－D矩阵分配的交通量在整个公路网中只产生17．9％的偏差,并且分配的路段交通量和计算出的交通量的差异在所有计算的路段中大大减少．     

Meta‐analysis of depression among marriage‐based migrant women in South Korea

Using meta‐analysis, this study examines the effect sizes of the variables related to depression and the moderating effects of depression among marriage‐based migrant women in South Korea to determine the implications for human service fields. This study identified 25 peer‐reviewed articles from 2000 to 2014 published in either Korean or in English. Results showed that (i) Korean language proficiency and economic hardship had significant effect sizes relative to depression; (ii) the psychosocial characteristics (i.e., acculturative stress, social support, marital satisfaction, life satisfaction, and self‐esteem) of this population had medium effect sizes relative to depression; and (iii) use of the Center for Epidemiological Studies Depression scale, residence in agricultural areas, average age, and average length of stay in Korea had significant moderating effects. Based on these results, the authors discuss social work practices and policies for this population, suggesting the priorization of marriage‐based migrant women in agricultural areas who have lived in Korea for short lengths of time.     

Partial functional linear regression

It is frequently the case that a response will be related to both a vector of finite length and a function-valued random variable as predictor variables. In this paper, we propose new estimators for the parameters of a partial functional linear model which explores the relationship between a scalar response variable and mixed-type predictors. Asymptotic properties of the proposed estimators are established and finite sample behavior is studied through a small simulation experiment.     

试论韩国的信息网络犯罪及相关文化政策

要想使信息网络文化政策得到有效的落实,就必须要惩治网络犯罪,韩国政府在打击网上赌博、网上卖淫、网络性暴力,以及网络空间的名誉损害行为等方面有其自己政策和做法.同时,韩国也在不断地借鉴世界各国及各地区打击网络犯罪方面的经验,说明一个国家文化政策的制订离不开和其他国家的配合与合作.     

Child,Mother, Father,and Teacher Beliefs About Child Academic Competence: Predicting Math and Reading Performance in European American Adolescents

Beliefs about child competence in math and reading have important implications for academic performance in adolescence. However, it is unclear whether children's own beliefs are the most important predictor of their academic performance or whether parents’ and teachers’ beliefs about child competence influence child academic performance. We assessed mothers’, fathers’, teachers’, and children's beliefs about European American children's (N = 189) competence in math and reading at age 10 and children's math and language performance at ages 10, 13, and 18 years. Confirmatory factor models demonstrated that children's and teachers’ beliefs had lower loadings on a latent variable of child competence in math and reading than mothers’ beliefs. Children's self‐competence beliefs in math and reading were not significantly correlated, suggesting children may use dimensional comparisons when assessing their own competence. Mothers’, fathers’, and teachers’ assessments of child competence in math were strongly correlated with their assessments of child competence in reading. Controlling for stability in academic performance, family socioeconomic status, and other reporters, mothers and fathers who rated their children's math competence higher had adolescents who performed better in math, and fathers who rated their children's reading competence higher had adolescents who performed better in language tasks. However, children who rated their own competence higher in math and reading had lower math and language (for girls only) performance in adolescence. European American children may use dimensional comparisons that render them poorer judges of their math and reading competence than parents.     

Parent Prevention Communication Profiles and Adolescent Substance Use: A Latent Profile Analysis and Growth Curve Model

ABSTRACT

This current study identifies distinct parent prevention communication profiles and examines whether youth with different parental communication profiles have varying substance use trajectories over time. Eleven schools in two rural school districts in the Midwestern United States were selected, and 784 students were surveyed at three time points from the beginning of 7th grade to the end of 8th grade. A series of latent profile analyses were performed to identify discrete profiles/subgroups of substance-specific prevention communication (SSPC). The results revealed a 4-profile model of SSPC: Active-Open, Passive-Open, Active-Silent, and Passive-Silent. A growth curve model revealed different rates of lifetime substance use depending on the youth’s SSPC profile. These findings have implications for parenting interventions and tailoring messages for parents to fit specific SSPC profiles.
