The First Youth Internet Safety Survey (YISS-1) is a telephone survey of a national sample of 1,501 youth, ages 10 to 17, and their parents, to assess the incidence, consequences and risk factors related to unwanted or illegal exposure of children and adolescents to sexual solicitation, harassment and pornography on the Internet and to determine children's and parent's knowledge of how to respond to such episodes. Results indicate that approximately one in five youth (19%)...

The role of species divergence due to ecologically-based divergent selection – or ecological speciation – in generating and maintaining biodiversity is a central question in evolutionary biology. Comparison of the genomes of phylogenetically related taxa spanning a selective habitat gradient enables discovery of divergent signatures of selection and thereby provides valuable insight into the role of divergent ecological selection in speciation. Tidal marsh ecosystems provide tractable opportunities for studying organisms’ adaptations to selective pressures that...

This study was conducted in 1976 at the University of New Hampshire. 2,134 respondents were interviewed in a nationwide sample of 960 males and 1,183 females. The purpose of the study was to ascertain methods of conflict resolution within the family. Information was gathered regarding the following areas: resolution of conflicts between spouses and between parents and children, including detailed information on the development of conflicts resulting in violence, resolution of conflicts in respondent's childhood...

This opinion study was designed to determine the prevalence of childhood sexual abuse among a national sample of adult men and women and to identify characteristics of victims and risk factors associated with childhood sexual victimization. The sampling frame included all residential telephones in the United States. 2,629 men and women 18 years or older were contacted by telephone during an eight day period in July of 1985. Knowledge and attitudes about sexual abuse were...

The First National Juvenile Online Victimization Study (N-JOV) examines the incidence and characteristics of juvenile online victimization cases, including sexual exploitation and child pornography cases, in the criminal justice system. The specific goals were to: provide sound national estimates of the number of juvenile online victimization cases ending in arrest during a one-year time period (July 1, 2000 through June 30, 2001); define categories and subcategories of juvenile online victimizations and describe case, offender and...

The 3rd National Online Victimization Study (NJOV-3) is the third wave of a longitudinal study. Wave 1 (NJOV-1) pertained to arrests for technology-facilitated crimes (e.g., sex offenders using the Internet to meet minors, solicitations to undercover investigators posing online as minors, downloading of child pornography) that occurred between July 1, 2000 and June 30, 2001; Wave 2 (NJOV-2) pertained to arrests during 2006. NJOV-3 collected data about technology-facilitated child sexual exploitation crimes ending in arrest...

A representative national sample of 6,002 families were studied with an emphasis on psychological and medical consequences, costs, and help-seeking patterns of intra-family violence. The study is a follow-up to the 1975 National Family Violence Survey.

The Developmental Victimization Survey (DVS), was designed to obtain one-year incidence estimates of a comprehensive range of childhood victimizations across gender, race, and developmental stage. Conducted between December 2002, and February 2003, it assessed the experiences of a nationally representative sample of children age 2-17 living in the contiguous United States.The sample selection procedures were based on a list-assisted random digit dial (RDD) telephone survey design. A short interview was conducted with an adult caregiver...
