Aim of this article is to examine parameters and types of Machiavellian behavior among students in selected departments. Social network analysis, bivariate analysis and principal component analysis have been implemented. A total sample of 27 students of Business Administration dept. (Thessaly University of Applied Sciences), 63 students of Veterinary dept. and 57 students of Physical Education dept. (University of Thessaly) has been analyzed. Selected results: Male students tend to regard more students as Machiavellians. Female students seem to be more willing to harm others. Male ones are more willing to exploit weaknesses. Tall or heavy students are regarded as quite Machiavellians. Students of urban origin or rich enough seem to adopt a relatively innocent view. Using internet is regarded as an evidence of Machiavellianism. To select friends by appreciating their knowledge capacity is considered to be unrelated to Machiavellianism. Two types of students who are targeted for Machiavellian practices are demarcated: a) “full target” and b) “beneficial target”. Two types of Machiavellian students appear: a) “full Machiavellian” and b) “ruthless”. A mixed typology of victims and Machiavellians reveals: a) a “targeting and targeted” type, b) a “full target”, c) a “beneficial target” and d) a “ruthless”. In general, the Machiavellianism seems to be either a generalized strategy or a quite specific one. 展开更多

Based on basic situational research and analysis carried out on 638 college students using network, we found that as many as 20 percent of the students are not only largely dependent on internet, but also addicted to it. Further biography characteristics analyses for different individuals on the four dimensions of the network forced addiction, tolerance, and time management and interpersonal relationship and health, show that there are significant differences in grades, gender with different education levels of their parents. Further researches on discrepancy that addicted groups have in network entertainment addiction, network information, cyber porn, network relations and network transactions addictions also illustrate that significant discrepancies exist in gender, net age, different discipline and other factors. Finally we put forward some correlative measures to solve the problems of college students network psychology from individuals, schools, and society levels. 展开更多

Clarifying the evolution structure of public opinion induced and spread by fragmentation in college students’ network circle group is the key to understanding college students’ online social psychological demands, grasping the development trend of public opinion, and designing targeted public opinion governance strategies. On the basis of identifying the key variables in the process of public opinion communication, DEMATEL-ISM model is used to explore the attribute positioning, relative importance level and hierarchical association mechanism of ante-variable and result variable, and then the governance strategies for fragment disordering public opinion in network circle groups of college students is designed. According to the study, exogenous stimuli, the uniqueness of discourse system, the number of spectacular texts and micro-narrative mode constituted the deep-rooted causes of fragment disordering public opinion. The unique situational and information attributes of network circle groups often become an important “booster” of disordered public opinion. The topic deviation is often accompanied with the formation of negative emotions. The corresponding public opinion governance strategies are sought from the aspects of shaping the network environment, adjusting the operation mechanism of the network circle group, improving the efficiency of using fragmented information, and optimizing the human resources of colleges. 展开更多

Social Networks Sites (SNSs) are dominating all internet users’ generations, especially the students’ communities. Consequently, academic institutions are increasingly using SNSs which leads to emerge a crucial question regarding the impact of SNSs on students’ academic performance. This research investigates how and to what degree the use of SNSs affects the students’ academic performance. The current research’s data was conducted by using drop and collect surveys on a large population from the University of Jordan. 366 undergraduate students answered the survey from different faculties at the university. In order to study the impact of SNSs on student’s academic performance, the research hypotheses was tested by using descriptive analysis, T-test and ANOVA. Research results showed that there was a significant impact of SNS on the student’s academic performance. Also, there was a significant impact of SNS use per week on the student’s academic performance, whereas no differences found in the impact of use of SNSs on academic performance due to age, academic achievement, and use per day to most used sites. The findings of this research can be used to suggest future strategies in enhancing student’s awareness in efficient time management and better multitasking that can lead to improving study activities and academic achievements. 展开更多

The current study uses a longitudinal, mixed-method approach to investigate the role that new media, such as social networking sites and video chat, play in cross-cultural adaptation and international student friendship network development. Results indicate that international students significantly increase and adapt their new media use while abroad to communicate globally with their friends and family, and locally with their newly formed relationships. Furthermore, social networking site host national friends do not necessarily lead to the development of face-to-face host national friends;however, interaction with established face-to-face host national friends and friend groups via new media platforms leads to an increased understanding of host communication patterns. Finally, this study proposes that researchers who apply Kim’s [1] cross-cultural adaptation theory consider incorporating Host New Media Communication as a principal concept. 展开更多

There are many reasons that motivate people to build online communities. The purpose of this study was to identify the topics that learners discuss when they are part of a computer assisted language learning course in order to answer the question “What are they talking about?”. We have examined an e-community of 618 students who were learning the Modern Greek language online. We analyzed their conversation topics directly from the discussion boards of the web-based course and sorted them into the pre-defined topic categories. The results of the study showed that during the first lessons of the course the students contributed more to social discussions which were unrelated to the course material. The reason of this outcome is that the students want to introduce themselves and meet their peers. As they progressed through the course’s lessons, however, their discussion topics became more course material related. The study ends with implications of the results and future research directions. 展开更多

Aim of this research is the detection of aggressive communication parameters and typology. A network sample of 62 students (male = 32, female = 30) and 4 instructors (male = 2, female = 2) at the physical education and sport sciences dept. at the University of Thessaly has been collected in 2016. A standardized questionnaire consisting of network and non-network part was used. Social network analysis (algebraic analysis) combined with conventional statistics has been used. Basic results are the following ones: Persons dedicated to sport appear to target others and be targeted. Dedication to study content is proved to play a role of a refuge against criticism. High grade and ambition seem to protect against negative comments. Physical qualification (tallness) seems also to discourage rudeness. Spatial-regional discrimination is also revealed. Mockery seems to be even a cause of absence from the courses. A superiority-induced aggressiveness (on economic basis) has been detected. Threat may be regarded as a behavioral extension of mockery (or inversely). In the course of study time, more aggressive persons emerge who even threat others. High grade students are unattractive for arguing. Internet seems to develop communication stimuli. The tendency for professional distinction is connected with arguing. Younger students show an integration deficit in terms of argumentation. Communicational types (three profiles of targets: “depreciated assaulted”, “attractive”, “repellent”, and two profiles of general involvement: “lively”, “controversial”) have emerged. A typology of targets is depicting a sharper fragmentation than a typology of general involvement (targeted and acting). 展开更多

In the era of We Media, online public opinion in colleges and universities has become an important front of ideological and political, with some characteristics such as concealment, diversity and sensitivity, interaction and immediacy of communication. It is urgent to carry out some researches about network public opinion analysis and guidance mechanism. It is a new challenge that the ideological and political education in colleges and universities, must face how to guide online public opinion effectively. The team building should be strengthened and the right of public opinion should be returned. The platform construction should be enriched, and it is important to give the chance to various media. Therefore, it should strengthen the mechanism construction, and public opinion guidance must be scientific and professional. Colleges and universities should build a clear network space from such aspects as the construction of network public opinion guidance institutions, the cultivation of opinion leaders, the perfection of early warning mechanism, the improvement of university network literacy and the guidance of campus media. 展开更多
