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...

Historical manuscript dating has always been an important challenge for historians but since countless manuscripts have become digitally available recently, the pattern recognition community has started addressing the dating problem as well. In this chapter, we present a family of local contour fragments (kCF) and stroke fragments (kSF) features and study their application to historical documen...

PROBLEM Little is known about dyadic processes that lead to adolescent dating violence. The purpose of this study was to examine the phenomenon of relationship ambiguity in adolescent dating relationships to better understand how ambiguity contributes to violence and aggression between dating partners. METHODS Data were drawn from 88 narratives of young adults who had participated in a study ...

Are women who have been the victim of psychological abuse in the past more likely to prefer an abusive dating partner in the future? Are men who have been the perpetrator of abuse more likely to prefer a dating partner with high attachment anxiety, a characteristic associated with victims of abuse? The present research used a highly repeated, within-subject, multilevel approach to identify the ...

This study investigates self-disclosure in the novel context of online dating relationships. Using a national random sample of Match.com members (N = 349), the authors tested a model of relational goals, self-disclosure, and perceived success in online dating. The authors’findings provide support for social penetration theory and the social information processing and hyperpersonal perspectives ...

15 Standard models of molecular evolution cannot estimate absolute speciation times alone, 16 and require external calibrations to do so. Because fossil calibration methods rely on the 17 unreliable fossil record, most nodes in the tree of life are dated with poor accuracy. However, 18 many major paleogeographical events are dated, and since biogeographic processes depend 19 on paleogeographica...
