Archaeologists have long recognized the problem of the ‘‘old wood’’ effect in radiocarbon dating charcoal and wood samples, the age of which may be hundreds of years older than their use by humans. Such problems have resulted in significant changes in how most researchers select wood and charcoal samples for C dating, with many now using relatively short-lived carbonized materials for dating. D...

Longitudinal survey data were used to examine the relationship between two types of childhood maltreatment, abuse/neglect and exposure to intimate partner violence (IPV), and two outcomes, substance use and dating violence, within the past year. Participants were youth (N = 158, aged 16-19 at Time 3) involved with child protective services (CPS). A parallel multiple mediator model was used to t...

OBJECTIVE Previous studies demonstrate significant associations between dating-violence victimization and sexual risk behaviors among adolescent girls; however, a relationship between dating violence and actual sexually transmitted disease (STD)/HIV testing and diagnosis has yet to be investigated among a representative sample. The present study assesses associations between dating violence and...

This study examined adolescents' interpersonal functioning, including the qualities of their closest friendships and romantic relationships, as predictors of dating/heterosocial anxiety. An ethnically diverse sample of 781 adolescents (57% girls; ages 15-19 years) completed measures that assessed the number and type of close friends, the presence of a romantic relationship, the qualities of the...

Theories imply that some aspects of adolescent dating behavior will be associated with individuals' positive psychosocial functioning, while other aspects will be associated with problems. This study addressed associations between diverse aspects of dating at age 16 and: (1) individual and social functioning at age 12 and at age 16; and (2) change in psychosocial functioning from age 12 to age ...

A recently developed dating method for glacier ice, based on the analysis of radiocarbon in carbonaceous aerosol particles, is thoroughly investigated. We discuss the potential of this method to achieve a reliable dating using examples from a midand a low-latitude ice core. Two series of samples from Colle Gnifetti (4450ma.s.l., Swiss Alps) and Nevado Illimani (6300ma.s.l., Bolivian Andes) demo...

This study investigates relationships between privacy concerns, uncertainty reduction behaviors, and self-disclosure among online dating participants, drawing on uncertainty reduction theory and the warranting principle. The authors propose a conceptual model integrating privacy concerns, self-efficacy, and Internet experience with uncertainty reduction strategies and amount of self-disclosure ...

Phytoliths can occlude some organic carbon during their deposition in plants. This carbon fraction is recognised as an ideal dating material because of its high resistance to decomposition and post-deposition contamination at the time of phytolith formation. However, the reliability of phytolith radiocarbon dating has recently been questioned. The development of a new extraction protocol for ph...

BACKGROUND Dating violence is a relevant current social and public health problem, not only due to adolescents exposure to risk of physical and mental injury, but also because it's at this age that romantic relationships begin with the possibility of these patterns of interaction to be perpetuated throughout life. The aim of this study is to characterize behaviours of violence and to identify t...
