Drawing the Line Between Essential and Nonessential Interventions on Intersex Characteristics With European Health Care Professionals

Human rights statements on intersex characteristics distinguish legitimate “medically necessary” interventions from illegitimate normalizing ones. Ironically, this binary classification seems partially grounded in knowledge of anatomy and medical interventions; the very expertise that human rights statements challenge. Here, 23 European health professionals from specialist “disorder of sex development” (DSD) multidisciplinary teams located medical interventions on a continuum ranging from “medically essential” to nonessential poles. They explained their answers. Participants mostly described interventions on penile/scrotal, clitoral/labial, vaginal, and gonadal anatomy whose essential character was only partially grounded in anatomical variation and diagnoses. To explain what was medically necessary, health care professionals drew on lay understandings of child development, parental distress, collective opposition to medicalization, patients “coping” abilities, and patients’ own choices. Concepts of “medical necessity” were grounded in a hybrid ontology of patients with intersex traits as both physical bodies and as phenomenological subjects. Challenges to medical expertise on human rights grounds are well warranted but presume a bounded and well-grounded category of “medically necessary” intervention that is discursively flexible. Psychologists’ long-standing neglect of people with intersex characteristics, and the marginalization of clinical psychologists in DSD teams, may contribute to the construction of some controversial interventions as medically necessary

Recent developments on the STAR detector system at RHIC

The STAR detector system is designed to provide tracking, momentum analysis and particle identification for many of the mid-rapidity charged particles produced in collisions at the RHIC collider. A silicon vertex detector (SVT) provides three layers of tracking near the interaction point. This is followed by the main time projection chamber (TPC), which continues tracking out to 200 cm radial distance from the interaction region. The detector design also includes an electromagnetic calorimeter, various trigger detectors, and radial TPCs in the forward region. The entire system is enclosed in a 0.5 T solenoid magnet. A progress report is given for the various components of the STAR detector system. The authors report on the recent developments in the detector proto-typing and construction, with an emphasis on the main TPC, recent TPC cosmic ray testing and shipping to Brookhaven National Laboratory

Publicly Funded Electric Carsharing Services Can Reduce Emissions and Expand Transportation Access, but They Need More Study [Policy Brief]

As funding grows, it becomes increasingly important to learn from carsharing services that have already been implemented. Researchers at the University of California, Davis and the non-profit organization Mobility Development reviewed evaluations of the travel, emissions, and equity effects of past US carsharing programs and analyzed the evolution of carsharing and its various business models. The aim of the research is to inform the design of and improve the value of investments in future electric carsharing programs, and this policy brief summarizes these findings and provides policy implications
