We present successful (81)Kr-Kr radiometric dating of ancient polar ice. Krypton was extracted from the air bubbles in four ∼350-kg polar ice samples from Taylor Glacier in the McMurdo Dry Valleys, Antarctica, and dated using Atom Trap Trace Analysis (ATTA). The (81)Kr radiometric ages agree with independent age estimates obtained from stratigraphic dating techniques with a mean absolute age of...

This study examined the characteristics of individuals who are more likely to engage in speed dating and online dating, and the types of people who are more likely to prefer these forms of dating. Older individuals and those who scored high on shyness were more likely to have tried online dating. Older individuals, those who scored high on shyness, and those who had tried online dating were mor...

Dating services will be judged by their success in bringing together compatible relationship partners. Thus a dating service has a responsibility to its customers to effectively facilitate this matching. This I take as the fundamental task of an honest dating service. The question of what the psychology literature on human dating can offer dating service designers is a question of how their res...

AIM To investigate what Zagreb University students think about professor-student dating. METHODS We surveyed 500 students from ten different Zagreb University schools using anonymous questionnaires. Twenty-five female and 25 male students from each school were asked to assess professor-student dating as either acceptable, reckless, unethical, or shameful, and decide how severely such behavior...

This mixed-methods study describes the norms supporting male-to-female and female-to-male dating violence in a diverse sample of ninth graders. The quantitative study, based on student surveys (n = 624), compared norms supporting dating violence by sex, race/ethnicity, and dating status, and it examined the relation between dating violence norms and physical aggression and victimization. The qu...

Online dating continues to grow rapidly in popularity every day, yet the role of social competence in online dating behavior remains unclear. This study was designed to expand previous research and conduct a comprehensive investigation on how social competence is associated with college students’ online dating behaviors, perceptions, and attitudes. Two hypotheses were tested: The social compens...

We present here the results of 44 paleomagnetic measurements, and single cosmogenic burial and optically stimulated luminescence ages for the Earlier Stone Age deposits from Wonderwerk Cave, Northern Cape, South Africa. The resulting paleomagnetic sequence: N>R>N>R>N constrains the Earlier Stone Age strata in this part of the site to between approximately 0.78-1.96 Ma. A single cosmogenic date ...

High-resolution measurements from Global Navigation Satellite System (GNSS) radio occultation (RO) provide atmospheric profiles with independent information on altitude and pressure. This unique property is of crucial advantage when analyzing atmospheric characteristics that require joint knowledge of altitude and pressure or other thermodynamic atmospheric variables. Here we introduce and demo...
