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

Homicides of Children and Youth. Crimes against Children Series. Juvenile Justice Bulletin.

This Bulletin provides information on the numbers and characteristics of two groups of children not frequently recognized in the literature on missing children: those involuntarily missing because they were lost, injured, or stranded and those missing for benign reasons. The estimates reported in this Bulletin are derived from two components of the Second National Incidence Studies of Missing, Abducted, Runaway, and Thrown away Children (NISMART 2): the National Household Survey of Adult Caretakers and the National Household Survey of Youth. These surveys were conducted during 1999 and reflect the experiences of children in the United States over a 12-month period. Because the vast majority of cases were concentrated in 1999, the annual period the Bulletin refers to is 1999.

♦ 6.1– Phase 1 mail survey data collection procedures ♦ 6.2– Phase 2 telephone interview data collection procedures ♦ 7.1– Data entry of case descriptions ♦ 7.2– Data entry and coding of quantitative data The N‐JOV study col‐ lected information from a national sample of law enforce‐ ment agencies about the characteristics of Internet sex crimes against minors and the numbers of arrests for these crimes during a one‐year period. The goals of our methodol‐ ogy were to 1) design a representative national sample of law enforcement agencies that would give us an overall picture of these crimes in the U.S., 2) understand how these cases emerged and were handled in a diverse group of agencies, and 3) get detailed data about the characteristics of these crimes from well‐informed, reliable sources. We used a two‐phase process to collect data from a national sample of local, county, state and federal law enforcement agencies. In Phase 1, we sent a mail survey to a national sample of law enforcement agencies asking if they had made arrests in Internet‐related child pornography or sexual exploi‐ tation cases between July 1, 2000 and June 30, 2001. In Phase 2, we conducted telephone interviews with law en‐ forcement investigators about a sample of the cases reported in the mail survey. The final data set, weighted to account for sampling procedures and other factors, includes data from 612 completed interviews. The first phase mail survey was sent to a national sample of 2,574 state, county and local law enforcement agencies. We created a stratified sample, dividing law enforcement agen‐ cies into three sampling frames based on their specialization or training in investigating Internet sex crimes against minors, so we could get information from agencies that specialized in these crimes and still allow every agency a chance to be se‐ lected in the sample.
