Cyberbullying is attracting social, political, and academic interest as the use of electronic devices such as computers and mobile phones by young people has increased dramatically. However, little is known about the factors involved in their perpetration, particularly in the context of college students' dating relationships. The aim of this study is to examine the involvement of college students in cyberbullying in the context of their dating relationships and to explore the impact of sexism on males' cyberbullying of their girlfriends. Participants are 219 undergraduate students from a university in the south of Spain. Results showed that 48.4% of participants reported having bullied their partners during the last year via mobile phone and 37.5% via Internet. Males reported a greater extent of cyberbullying of their girlfriends through both means. Regression analyses indicated that males' levels of hostile sexism are related to males' cyberbullying of their girlfriends. These findings suggest a modernization in the forms of violence toward women among college students and also expand current literature by revealing the influence of participants' hostile sexism on this type of cyber aggression against women in dating relationships.

Effectiveness of mediation strategies is analyzed in two different types of collective labor conflicts: rights conflicts and conflicts of interests. The sample consists of 106 professional labor mediators who completed a questionnaire about the strategies they used and the outcomes they achieved in their most recent mediation intervention. Results from regression analysis indicate that while the use of substantive and contextual strategies is positively related to effectiveness in both types of conflict, the use of reflexive strategies is negatively related to effectiveness, particularly in rights conflicts.

The changing demographic structure of the population, resulting in unparalleled growth of the elderly population, means that e-inclusion of this population group is considered to be a social and political priority in the context of the Information Society. Most research studies have only considered individual variables -such as age, gender, education, income and health- in the explanatory models of e-inclusion of senior citizens, while ignoring macro variables, such as the welfare systems and public policies in each country. Simultaneously, most studies focus on small-scale samples, lack international comparisons and do not consider the combined effect of several variables that influence Internet use. This study aims to analyse possible differences between two countries that have different welfare systems and public policies, after controlling for the effects of the individual variables that have been identified in the literature as relevant for Internet use. The study focuses on a sample of 8639 individuals, aged 50 years and over, residing in Portugal and Estonia, who participated in the SHARE project (Survey of Health, Ageing and Retirement in Europe). The results of the logistic regression analysis demonstrate that welfare systems and public policies have an impact on the likelihood of Internet use, thus reinforcing the importance of developing public policies to foster e-inclusion of senior citizens.

Mobile devices have contributed to fuel Internet use and in particular social network sites. Instagram has now become one of the most popular social network sites. Along with this growth, concerns arise about problematic use. ''Likes'' are one of the main factors catching people's attention due to their rewarding power. Particularly, during adolescence, likes are considered a sign of social approval. Surprisingly, the study of likes relationship to problematic use is scarce. In contrast, the direct effect of variables such as self-esteem on problematic use has been widely analyzed, but moderation studies to underscore the dynamics with other variables are scarce. The aim of this study is to expand current literature by analyzing the influence of likes and self-esteem on Instagram problematic use and the moderating role of self-esteem in the relationship between likes and problematic use. Participants were 244 teenagers. Regression analysis with Process macro for SPSS evidence the impact of likes on problematic use and the moderating role of self-esteem, serving as a protective factor, so that the impact of likes increase on problematic use is lower in participants with higher self-esteem compared to those with lower self-esteem. Results open the door for future research as well as for intervention efforts to benefit from social network use, while reducing teen's problematic use.

Living alone has been indicated as a key variable to explain loneliness in older adults. In contemporary society, where technology has become one of the main means of communication and personal interaction, has the internet influenced the relationship between living alone and loneliness? This paper aims to answer this research question by using a sample of 64,297 individuals who were surveyed in SHARE project wave 6in European countries with different welfare regimes (Portugal,

This study analyzes Portuguese seniors' Internet activity and determine their reasons, benefits, and motivations for web use as well as the obstacles faced by non-users. Results were derived from a questionnaire completed by 189 seniors enrolled in universities for seniors. 68.1 % defined themselves as Internet users. The seniors asked principally go online to check e-mail and gather information. They state that the Internet is useful, helps them to stay up-to-date, and to preserve (but not expand) relationships. Non-user status is not attributed to old age or health reasons. According to the technology acceptance model, ease of use and perception of utility were related to both Internet use and its intensity of use. Family influence also played a key role. Gender differences were not found in Internet use, intensity of use, or in use motivations.
