Gendertyping sports: social representations of masculine,feminine, and neither-gendered sports among US university students

Sport is shifting from being hegemonically masculine but it is unclear how sports are viewed as gender segregated or gender integrated. Previous quantitative studies of gendertyping sports have reported mixed findings. Gendertyping constructs social representations that shape institutional and individual sport activities. This study examined how particular sports are represented as masculine, feminine and/or neither-gendered in one sample of 310 students at a US university. Qualitative open-ended recall questions asked students to name three masculine, feminine and neither masculine nor feminine sports. Results revealed that most students were aware of and used hegemonic gendertyped terms to describe sports. Recall questions elicited 2515 namings of 80 different sports that were arrayed as a spectrum of social representations of gendertyped sports ranging from masculine to neither-gendered to feminine. Some representations were hegemonic segregated masculine sports, many were integrated neither-gendered sports, and fewer were segregated feminine sports. Gendertyped social representations of sports offer cultural toolkits for calibrating the practices of doing and redoing gender in sport.     

Models of school-age child care: A review of current research on implications for women and their children

This article discusses various models of children's out-of-school care arrangements, mainly in the United States of America. Forms of care include programs or centers, family day care homes, and self-care. The implications of each of these different systems of care and outcomes for both children and their parents are reviewed through the lens of existing research. While there is no consensus in the research literature, so-called “latch-key” children appear to experience more negative effects than supervised peers, although these negative effects may be mitigated by variables, such as the amount of time spent alone and the parent-child relationship. A small group of studies finds positive outcomes for children who participate in recreational after-school programs, although age-inappropriate care arrangements and age of participating child may be associated with negative outcomes. No research has been conducted across program types. Many mothers of school-age children without regular after-school care or alternative care on school holidays, appear to accomodate their career and work choices to their children's schedules, possibly in order to avoid the “latch-key” alternative.     

The effects of delayed menarche in different contexts: Dance and nondance students

The premise that effects of maturational timing are mediated by social context is explored by comparing adolescent girls in dance and nondance schools. Because the dance student must maintain a relatively low body weight, being a late maturer (who is often leaner than an on-time maturer) is expected to be more advantageous to the dancer than to the student not required to meet a weight standard. Girls aged 14 to 18 were seen; 276 attended private schools and 69 attended national ballet company schools. AllSs were weighed and measured and asked questions about their secondary sexual development, weight-related concerns, eating concerns, adult sex-role expectancies, body image, emotional functioning, and family relationships. Menarcheal age was used to classify girls as early (before 11.5 years of age), on time (between 11.5 and 14 years), and late maturers (after 14 years). More dance than non-dance school students were late maturers (55% versus 29%). The dance students weighed less and were leaner, had higher eating scores, and had lower family relationship and impulse control scores than the comparison sample. Across groups, late maturing students weighed less, were leaner, and had lower diet and higher oral control scores than on-time maturers, with the differences more pronounced in the dance than nondance students. In addition, the on-time dancers had higher psychopathology, perfection, and bulimia scores and lower body image scores than the late maturing dancers. The findings are discussed in terms of a goodness of fit between the requirements of a social context and a person's physical and behavioral characteristics.This paper was prepared with the support of grants from the W.

Plasma,oral fluid and sweat wipe ecstasy concentrations in controlled and real life conditions

In a double-blind placebo controlled study on psychomotor skills important for car driving (Study 1), a 75 mg dose of +/- 3,4-methylenedioxymethamphetamine (MDMA) was administered orally to 12 healthy volunteers who were known to be recreational MDMA-users. Toxicokinetic data were gathered by analysis of blood, urine, oral fluid and sweat wipes collected during the first 5h after administration. Resultant plasma concentrations varied from 21 to 295 ng/ml, with an average peak concentration of 178 ng/ml observed between 2 and 4h after administration. MDA concentrations never exceeded 20 ng/ml. Corresponding MDMA concentrations in oral fluid, as measured with a specific LC-MS/MS method (which required only 50 microl of oral fluid), generally exceeded those in plasma and peaked at an average concentration of 1215 ng/ml. A substantial intra- and inter-subject variability was observed with this matrix, and values ranged from 50 to 6982 ng/ml MDMA. Somewhat surprisingly, even 4-5h after ingestion, the MDMA levels in sweat only averaged 25 ng/wipe. In addition to this controlled study, data were collected from 19 MDMA-users who participated in a driving simulator study (Study 2), comparing sober non-drug conditions with MDMA-only and multiple drug use conditions. In this particular study, urine samples were used for general drug screening and oral fluid was collected as an alternative to blood sampling. Analysis of oral fluid samples by LC-MS/MS revealed an average MDMA/MDEA concentration of 1121 ng/ml in the MDMA-only condition, with large inter-subject variability. This was also the case in the multiple drug condition, where generally, significantly higher concentrations of MDMA, MDEA and/or amphetamine were detected in the oral fluid samples. Urine screening revealed the presence of combinations such as MDMA, MDEA, amph, cannabis, cocaine, LSD and psilocine in the multiple-drug condition.     

Identification of exhumed remains of fire tragedy victims using conventional methods and autosomal/Y-chromosomal short tandem repeat DNA profiling

In a fire tragedy in Manila in December 1998, one of the worst tragic incidents which resulted in the reported death of 23 children, identity could not be established initially resulting in the burial of still unidentified bodies. Underscoring the importance of identifying each of the human remains, the bodies were exhumed 3 months after the tragedy. We describe here our work, which was the first national case handled by local laboratories wherein conventional and molecular-based techniques were successfully applied in forensic identification. The study reports analysis of DNA obtained from skeletal remains exposed to conditions of burning, burial, and exhumation. DNA typing methods using autosomal and Y-chromosomal short tandem repeat (Y-STR) markers reinforced postmortem examinations using conventional identification techniques. The strategy resulted in the identification of 18 out of the 21 human remains analyzed, overcoming challenges encountered due to the absence of established procedures for the recovery of mass disaster remains. There was incomplete antemortem information to match the postmortem data obtained from the remains of 3 female child victims. Two victims were readily identified due to the availability of antemortem tissues. In the absence of this biologic material, parentage testing was performed using reference blood samples collected from parents and relatives. Data on patrilineal lineage based on common Y-STR haplotypes augmented autosomal DNA typing, particularly in deficiency cases.
