It’s a journey: from media effects to dynamic systems

ABSTRACT

This paper aims to demonstrate how an analytical paradigm shift from the General Linear Model (GLM) used in most communication processes and effects research to dynamic systems theory (DST, a nonlinear mathematical theory), fundamentally changes one’s research assumptions and research questions and leads to novel approaches to research design, data collection, and analysis. Concrete examples demonstrating these changes are drawn from the co-viewing literature. In addition, we discuss how data collected and interpreted using the GLM can be re-analyzed and re-interpreted to further inform our understanding of communication behavior when we use the assumptions of dynamic systems theory to derive new predictions.     

Psychosocial–Environmental Risk Factors for Suicide Attempts in Adolescents with Suicidal Ideation: Findings from a Sample of 73,238 Adolescents

We determined risk factors that discriminate between suicide attempt (SA) adolescents and suicidal ideation only (SI only) adolescents using data from the 2010 Korea Youth Risk Behavior Web‐based Survey (12–19 years; N = 73,238). In males, heavy alcohol use, drug use, and high perceived sadness/hopelessness showed significant effects on the presence of SA versus the presence of SI only. In females, along with these variables, low academic achievement, poor perceived health status, high perceived stress, and unhealthy coping strategy were also significantly related to the presence of SA versus SI only. Therefore, clinical interventions targeting adolescents' psychological distress are warranted to prevent suicide.     

关于religion几个中文译名的解析

对作为或一度作为religion译名的神教、神学、宗教、教等词语进行梳理与分析时发现,目前流行通用的"宗教"一词存在着先天性语源缺陷。相比之下,"教"字较之其它译名差强人意,但须力避与现代教育之"教"的混用,尽管其历史以来亦不乏教育之本质属性的表达。在religion的译名选择上,外延的广狭度应成为一个考量的因素,即使之更加契合文化的属性,从而拓宽东西方交流的平台应成为今后致力的一个方向。

An experimental investigation on a nanoporous carbon functionalized liquid damper

The behaviour of a p-xylene-based lyophobic nanoporous carbon system under high hydrostatic pressures is investigated. As the pressure is increased to a critical value, the nanopore surfaces between graphene layers are exposed to the liquid phase, leading to a considerable increase in solid–liquid interfacial energy. During unloading, defiltration does not occur until the pressure is much lower. Thus, the system is energy absorbing. Owing to the large solid–liquid contact area, the energy absorption efficiency is much higher than that of conventional dampers.     

Evidence for the Phase Transition from Rule I to Rule II on the Balance Scale Task

A central and recurrent theme in developmental psychology is the question whether development proceeds continuously or discontinuously. This question is difficult to answer because the two types of development may be hard to distinguish. To investigate whether change is discontinuous, one requires a formal model for discontinuous development. Such a model should provide operational, empirical criteria to investigate the nature of development. The cusp model, which is derived from catastrophe theory, is a formal model of discontinuity that provides such criteria. Eight criteria, so-called catastrophe flags, can be derived from the model. Some of these flags are predicted in other models of discontinuity, but others, notably hysteresis, are unique to catastrophe theory. In the present research, it is tested whether the transition from Rule I to Rule II on the balance scale task proceeds discontinuously. The present research centers around five catastrophe flags: bimodality, inaccessible region, sudden jump, divergence, and hysteresis. Two experiments are reported. In Experiment 1, a paper-and-pencil version of the balance scale task was administered to 314 children who were 6 to 10 years old. In Experiment 2, an adapted version of the test was administered to 302 children who were 6 to 10 years old. Bimodality, inaccessible region, hysteresis, and sudden jump were clearly observed. Divergence was not observed. The presence of four of the five flags strongly supports the hypothesis that the transition from Rule I to Rule II is discontinuous.     

美国青年的宗教信仰状况研究

本文通过对美国青年宗教信仰状况相关研究的梳理,呈现了美国青年宗教信仰的一些典型变化和发展。美国青年的宗教信仰状况体现了20世纪以来西方社会宗教世俗化、私人化的整体发展趋势。借鉴美国的情况,我们应坚守自身立场,扎根本土、结合时代,以一种严谨科学的态度推进我国青年的宗教信仰状况研究。     

小经文献与伊斯兰教相关问题研究

小经是回等民族使用的一种阿拉伯字母体系拼音文字,而用小经译、撰的文献具有丰富的内容,是研究中国伊斯兰教重要的关注点。但以往,学者研究中国伊斯兰教所依据的资料主要为汉译著述,由此来说明中国伊斯兰教的特点,却忽视了小经文献的研究,结果其所研究的成果反映的是汉译著述,并不是伊斯兰教的全部。笔者以为有必要研究小经文献所反映的伊斯兰教内容。这些内容对中国特色的伊斯兰教起到有益的补充,且为我们全面认识中国伊斯兰教提供了另一门径。
