Removal of natural steroid hormones from wastewater using membrane contactor processes.

Abstract: Growing demands for potable water have strained water resources and increased interest in wastewater reclamation for potable reuse. This interest has brought increased attention to endocrine-disrupting chemicals (EDCs) as emerging water contaminants. The effect of EDCs, and in particular natural steroid hormones, on humans is of heightened interest in the study of wastewater reuse in advanced life support systems (e.g., space missions) because they are excreted in urine and have high endocrine-disrupting potencies. Direct contact membrane distillation (DCMD) and forward osmosis (FO) are being investigated for wastewater treatment in space. Retention of two natural steroid hormones, estrone and 17beta-estradiol, by these two processes was evaluated in the current investigation. DCMD provided greater than 99.5% hormone rejection; DCMD also provided constant flux, greater than 99.9% urea and ammonia rejection, and high water recovery. FO provided from 77 to 99% hormone rejection depending on experiment duration and feed solution chemistry.

Asking the gatekeepers: a national survey of judges on judging expert evidence in a post-Daubert world.

Abstract: Drawing on the responses provided by a survey of state court judges (N = 400), empirical evidence is presented with respect to judges' opinions about the Daubert criteria, their utility as decision-making guidelines, the level to which judges understand their scientific meaning, and how they might apply them when evaluating the admissibility of expert evidence. Proportionate stratified random sampling was used to obtain a representative sample of state court judges. Part I of the survey was a structured telephone interview (response rate of 71%) and in Part II, respondents had an option of completing the survey by telephone or receiving a questionnaire in the mail (response rate of 81%). Survey results demonstrate that judges overwhelmingly support the "gatekeeping" role as defined by Daubert, irrespective of the admissibility standard followed in their state. However, many of the judges surveyed lacked the scientific literacy seemingly necessitated by Daubert. Judges had the most difficulty operationalizing falsifiability and error rate, with only 5% of the respondents demonstrating a clear understanding of falsifiability and only 4% demonstrating a clear understanding of error rate. Although there was little consensus about the relative importance of the guidelines, judges attributed more weight to general acceptance as an admissibility criterion. Although most judges agreed that a distinction could be made between "scientific" and "technical or otherwise specialized" knowledge, the ability to apply the Daubert guidelines appeared to have little bearing on whether specific types of expert evidence were designated as "science" or "nonscience." Moreover, judges' "bench philosophy of science" seemed to reflect the rhetoric, rather than the substance, of Daubert. Implications of these results for the evolving relationship between science and law and the ongoing debates about Frye, Daubert, Joiner, and Kumho are discussed.

“I can’t get no satisfaction”: Insecure attachment, inhibited sexual communication, and sexual dissatisfaction

Abstract: An Internet survey was conducted to extend the investigation of attachment style to the domains of sexual communication and sexual satisfaction. We hypothesized that insecure attachment would be associated with sexual dissatisfaction, mediated by inhibited communication of sexual needs. Further, the association of attachment with inhibited communication was expected to be mediated by attachment-related tendencies toward deference to partners’ needs, concern with the relationship implications of sexual choices, general anxiety regarding sex, and feelings for one’s partner. Somewhat different mediational pathways were predicted for each of the 2 dimensions of attachment insecurity: anxiety and avoidance. Respondents (N ¼ 1,989, around half of them involved in a sexual relationship at the time of the study and half not involved but with previous sexual relationship experience) completed measures of attachmentrelated anxiety and avoidance, neuroticism (a possible confound), and sexual communication and satisfaction. Results generally supported the hypotheses and provided additional evidence regarding the associations between attachment style, sexual communication, and sexual satisfaction.
