This study examines the relationship between dating violence, forced sexual intercourse (FSI), and four measures of sexual risk taking (i.e., age at first sex, number of recent (within the last three months) sex partners, alcohol/drug use at last sex, and condom use at last sex) among a sample of 1124 ethnically diverse sexually active adolescents in Illinois. Given conflicting reports regardin...
This paper presents an analysis of online dating fraud’s geography. Working with real romance scammer dating profiles collected from both proxied and direct connections, we analyse geographic patterns in the targeting and distinct characteristics of dating fraud from different countries, revealing several strong markers indicative of particular national origins having distinctive approaches to ...
The most common dating goals of adolescents are identity, intimacy, status and sex. In this study of Australian youth (16-30 years, N = 208), dating goals were expected to explain goal-consistent behavior in each domain. Also, goals coupled with consistent behavior were expected to be associated with greater satisfaction in each domain. Age, gender, same-sex versus other-sex attraction, and coh...
Little is known about adolescent boys' motives for dating, although stereotypical portrayals highlight a desire for sexual behavior. This issue was examined from a normative perspective that connected dating motives to intercourse motives, masculinity, and dating and sexual behaviors. Data from 105 racially and economically diverse 10th-grade boys were analyzed. Results indicated that the most ...
We consider the problem of estimating causal influences between observed processes from time series possibly corrupted by errors in the time variable (dating errors) which are typical in palaeoclimatology, planetary science and astrophysics. “Causality ratio” based on the WienerGranger causality is proposed and studied for a paradigmatic class of model systems to reveal conditions under which i...

Characterization of the user online dating behavior helps us to obtain a deep understanding of their dating preference and make better recommendations on potential dates. In this paper...
3 In this paper we examine the effects of preadolescent parenting strategies on timing of adolescents' dating and sexual initiation. Using data from the two waves of the National Survey of Families and Households (1987-88 and 1992-94) involving interviews with parents as well as adolescents four years later, we estimate the effects of preadolescent parental support, coercive control, and monito...
Bone collagen is a well-characterized and generally robust protein that plays a key role in both radiometric dating and stable isotopic reconstruction of paleodiet. To be useful for such purposes, however, analyzed collagen must be relatively taphonomically unaltered. To date, little research has been conducted to document the taphonomic fate of bone collagen from archaeological sites in the tr...
Human settlers transported chickens (Gallus gallus domesticus) to most East Polynesian archipelagos between AD 1000 and 1300; however, it has long been assumed that New Zealand was an exception. Despite the fact that chicken bones have been recovered from localities of early archaeological middens in New Zealand, their age and genetic relationships have never been critically assessed. Here, we ...
In cellular communications there are two primary communication links between the cell’s central basestation and the users, the uplink (or reverse link) and the downlink (or forward link). The former refers to the flow of information from the users to the basestation, and is a problem which has been and is still today the subject of much debate. The downlink, however, receives less attention, si...
