An analysis of the development and use of theory in library and information science research articles

This study identifies the state and characteristics of theoretical research in library and information science journals by examining the number and the quality of theory incidents. Theory incident is characterized as an event in which the author contributes to the development or the use of theory in his/her own paper. This study assumes that both theory building and theory use are intertwined to construct a cohesive body of knowledge in the filed. Theory incidents were identified by a content analysis of 1661 articles in four LIS journals from 1984 to 2003. The findings suggest that 41.4% of the articles contributed to the development or use of theory. The overall proportion of theoretical articles has increased. They showed a tendency to converge into a few subfields, such as information seeking and use or information retrieval. However, the declining share of theory development articles in recent journal issues and the overall low level of theory incidents are urging LIS researchers to the importance of continuous and creative research in LIS.     

Physical education teachers' beliefs and intentions toward teaching students with disabilities

The Theory of Planned Behavior (TpB) measures the effect that individuals' behavioral belief normative belief and control beliefs have on their intentions to perform a specific behavior The purpose of this study was to examine: (a) whether the TpB could predict physical educators' intentions and (b) whether physical educators' intentions and control beliefs could predict their self-reported teaching behavior. A sample of 220 physical educators completed the questionnaire. Stepwise multiple regression analysis revealed that the TpB significantly predicted physical educators' intentions, F(3, 216) = 57.21, p < .01. However, only intention was a significant predictor of physical educators'self-reported behavior in teaching students with disabilities, F(2, 123) = 34.04, p < .01.     

Political homophily on social network sites and users' poll skepticism

Although many studies have investigated citizens' attitudes toward polls and the political consequences, there have been no studies examining the effects of social network site (SNS) users' opinion environments on their poll skepticism. Based on prior studies on poll skepticism, we examine the relationship between perceived SNS opinion environments, poll skepticism, perceived concerns over the negative influence of the polls, and voting intention in an upcoming election. Using the survey data of the 2012 South Korean General Election, this study found that if the published polls are against respondents' political position, their homophilous SNS opinion environments promote poll skepticism, and augmented poll skepticism leads to concerns over the negative influence of the polls on other voters, which in turn increases voting intention.     

Cultural differences in how individuals explain their lying and truth-telling tendencies

This study investigated how cultural differences between Korea and the United States in attitudinal and normative components affect individuals’ explanation of their intentions to lie or tell the truth. Study 1 examined individuals’ intentions to base their lying or truth-telling tendencies on attitude-related reasons (i.e., attitudinal reasons) and subjective norm-related reasons (i.e., normative reasons). Study 2 examined individuals’ evaluation of a person who used attitudinal reasons or normative reasons to explain his/her behaviors of lying or truth-telling. The results showed that neither culture used one type of reason consistently across different behaviors. Instead, the types of behaviors influenced the way attitudinal and normative components were related to behavioral intentions. The attitudinal component was important for individuals’ explanations of their attitudinal reasons to lie and to tell the truth and that the normative component was important for individuals’ explanations of their normative reasons to lie. However, both the attitudinal and normative components were important for individuals’ explanations of their normative reasons to tell the truth. Cross-culturally, Koreans were more likely to use normative reasons when they had to explain why they intended to lie for a friend, whereas Americans were more likely to use normative reasons when they had to explain why they intended to tell the truth. In addition, Koreans and Americans had different preferences for each reason type depending on the type of behavior probably because Koreans, as compared to Americans, tend to view lying for a friend less negatively.     

The Historical and Cultural Identity of Taekwondo as a Traditional Korean Martial Art

Taekwondo's cultural identity is considered in the light of the controversy over its historical origins. After reviewing several existing theories, the meaning and development of taekwondo as a Korean martial art is explored. There are two conclusions: first, taekwondo is a fusion of several different sources; second, taekwondo is essentially a martial art that focuses on foot skills, and this distinguishes it from Japan's karate and China's wushu, which are primarily based on hand skills. The fact that all terms are rendered into pure Korean words shows the essence of Korean localization. Thus taekwondo incorporates a distinct identity as a Korean martial art.     

Quantification of the physiological loading of one week of “pre-season” and one week of “in-season” training in professional soccer players

Abstract

The aim of this study was to quantify the physiological loads of programmed “pre-season” and “in-season” training in professional soccer players. Data for players during each period were included for analysis (pre-season, n = 12; in-season, n = 10). We monitored physiological loading of training by measuring heart rate and rating of perceived exertion (RPE). Training loads were calculated by multiplying RPE score by the duration of training sessions. Each session was sub-categorized as physical, technical/tactical, physical and technical/tactical training. Average physiological loads in pre-season (heart rate 124 ± 7 beats · min^?1; training load 4343 ± 329 Borg scale · min) were higher compared with in-season (heart rate 112 ± 7 beats · min^?1; training load 1703 ± 173 Borg scale · min) (P < 0.05) and there was a greater proportion of time spent in 80–100% maximum heart rate zones (18 ± 2 vs. 5 ± 2%; P < 0.05). Such differences appear attributable to the higher intensities in technical/tactical sessions during pre-season (pre-season: heart rate 137 ± 8 beats · min^?1; training load 321 ± 23 Borg scale · min; in-season: heart rate 114 ± 9 beats · min^?1; training load 174 ± 27 Borg scale · min; P < 0.05). These findings demonstrate that pre-season training is more intense than in-season training. Such data indicate that these adjustments in load are a direct attempt to deliver training to promote specific training adaptations.     

The Effect of Online Media Platforms on Joining Causes: The Impression Management Perspective

Drawing on the impression management theory, this study examined the effect of online media platforms, social network sites (SNSs) versus non-SNSs, on the intention to join a cause. The online experimental study discovered that the SNS was more effective in increasing the intention to join a cause than the non-SNS. The findings also demonstrated the mediating role of the perceived visibility of joining the cause and the moderating role of public self-consciousness on this effect. Further, self-cause image congruence positively influenced the intention to join the cause, while it did not moderate the effect of online media platforms.     

大学为学生提供了什么样的信息技术经历：现状及效果的探析--基于南京大学与首尔大学的问卷调查

大学生的信息技术经历是其大学就读经历中的一个重要组成部分,分析大学生信息技术经历的现状及其对学业结果的促进效果,是探究本科教育质量的重要路径。通过对中国南京大学和韩国首尔大学的问卷调查,课题组发现,南京大学样本的信息技术经历的性别差异、家庭背景差异、生源地差异、年级差异、学科差异等都非常显著,首尔大学样本除了在年级和学科等因素上存在个别指标（即信息技术使用状况）的差异之外,在其他所有背景因素上都不存在显著的差异性。回归分析则表明,中韩本科生的“信息技术使用状况”和“信息技术使用的积极意向”都会对各种学术性学习结果产生显著的正向影响,但“信息技术使用的消极意向”均不会对各种学术性学习结果产生显著的负向影响。在定量分析和定性访谈的基础上,课题组认为,关注对弱势群体学生的信息技术使用经历、意向和能力的支持和帮助;关注对教师信息技术能力的提升;改革刚性的教学评价制度,发挥信息技术真正支持教学的潜力;将学生的信息技术能力（特别是学术信息的搜集、整理和交流能力）纳入到培养目标和考评体系中来等四个方面,是改进本科生信息技术经历、提升学生学习结果的重要实践策略。
