Social network sites SNSs are increasingly attracting the attention of academic and industry researchers intrigued by their affordances and reach This special theme section of the Journal of Computer-Mediated Communication brings together scholarship on these emergent phenomena In this introductory article, we describe features of SNSs and propose a comprehensive definition We then present one perspective on the history of such sites, discussing key changes and developments After briefly summarizing existing scholarship concerning SNSs, we discuss the articles in this special section and conclude with considerations for future research

Removing the child--prosecuting the offender in cases of sexual abuse: evidence from the national reporting system for child abuse and neglect.

Let's prevent peer victimization, not just bullying

This paper uses data from a national survey of adolescent Internet users (N = 1,501) to describe online relationships. Fourteen percent of the youths interviewed reported close online friendships during the past year, 7% reported face-to-face meetings with online friends, and 2% reported online romances. Two hundred forty-six youths provided details about one close online relationship. Most of these relationships were with same-age peers (70%) and crossed gender lines (71%). Many intersected with face-to-face social networks because they were initiated by introductions from friends or family (32%), involved people who lived in the vicinity (26%), were known to parents (74%), included offline contact by mail or telephone (70%), or involved face-to-face meetings (41%). Few youths reported bad experiences with online friends.

Polyvictimization and youth violence exposure across contexts

Using two waves of the Developmental Victimization Survey (DVS), this research examined the effects of different forms of child victimization on changes in self-concept in a national sample of 11- to 18-year-old youth. Specifically, we (a) assessed the independent effects of past-year sexual victimization, nonsexual child maltreatment, peer victimization, and nonvictimization adversity on changes in mastery and self-esteem, (b) investigated the effects of these stressors on levels of depressive symptoms, and (c) determined the extent to which changes in mastery and/or self-esteem mediate associations between victimization and depression. Results indicate that only sexual victimization independently reduced self-esteem, and there were no significant changes in mastery in response to victimization exposure. Declines in self-esteem partially mediated the association between past-year sexual victimization exposure and levels of depressive symptoms. Strong direct effects of each form of victimization and nonvictimization adversity on depression were also evident. Results suggest that sexual victimization experiences may have uniquely powerful effects on self-esteem that are not apparent for other types of victimization and stress.
