Competing Gender Paradigms: Gender Difference, Fetal Rights and the Case of Johnson Controls

Political debates over the concept of “fetal rights” pose in sharp relief questions regarding the meaning of biological gender difference for gender equality. Can the state's obligation to “protect” fetal health be used to modify or control women's behavior? If so, what does this mean for women's status as full and equal citizens in a democratic society? This article addresses these questions through an analysis of the political, legal, scientific and moral debates over “fetal protection policies” in hazardous workplaces.

The social context of teenage childbearing: Effects on the infant's care-giving environment

The effects of maternal age and the social context on the home environment, and maternal behaviors of adolescent and older mothers, as well as the stability of the care-giving environment, were studied. Fifty low-middle socioeconomic status (SES), primiparous, Caucasian mothers and their fullterm healthy infants were included. At four months, support systems and life stress were assessed, as well as the home environment and maternal behaviors. At two years, a similar home visit was conducted in a subsample. Adolescent mothers had less education, lower SES, and a different child care support system. They also differed in the home environment and maternal behaviors at four months. Some of these differences disappeared when maternal education and SES, or child care support and life stress, were controlled. Moderate correlations were observed between four months and two years home environment and maternal verbalizations. Thus, a combination of maternal age and other social factors mediate the negative characteristics of the adolescent mother's care-giving environment, which is relatively stable during the infancy period.Received Ph.

Physical attractiveness as a mediator of the impact of early pubertal changes for girls

The present study examined the effects of early pubertal development and physical attractiveness on the popularity, body image, and self-esteem of over 200 sixth-grade girls. Two rival hypotheses were explored. The first suggests that physically attractive girls, because of their more favorable social environment, will exhibit fewer psychosocial difficulties than unattractive girls during pubertal development. The second hypothesis argues that attractive girls will exhibit greater difficulty during pubertal transition because their self-image is more intimately connected with their physical appearance. Although there were no significant interactions between attractiveness and pubertal development for either popularity or body image, the second hypothesis was supported with respect to self-esteem. Specifically, developing attractive girls exhibited lower self-esteem than their unattractive counterparts. The results are discussed in terms of the relative vulnerability to bodily changes of girls differing in physical attractiveness.Support for this work was provided by NIMH Grant 2 R01 MH-30739 and the William T.

Additional predictions for forensic DNA phenotyping of externally visible characteristics using the ForenSeq and Imagen kits

Multiplex DNA typing methods using massively parallel sequencing can be used to predict externally visible characteristics (EVCs) in forensic DNA phenotyping through the analysis of single-nucleotide polymorphisms. The focus of EVC determination has focused on hair color, eye color, and skin tone as well as visible biogeographical ancestry features. In this study, we researched off-label applications beyond what is currently marketed by the manufacturer of the Verogen ForenSeq kit primer set B and Imagen primer set E SNP loci. We investigated additional EVC predictions by examining published genome wide sequencing studies and reported allele-specific gene expression and predictive values. We have identified 15 SNPs included in the ForenSeq kit panel and Imagen kits that have additional EVC prediction capabilities beyond what is published in the Verogen manuals. The additional EVCs that can be predicted include hair graying, ephelides hyperpigmented spots, dermatoheliosis, facial pigmented spots, standing height, pattern balding, helix-rolling ear morphology, hair shape, hair thickness, facial morphology, eyebrow thickness, sarcoidosis, obesity, vitiligo, and tanning propensity. The loci can be used to augment and refine phenotype predictions with software such as MetaHuman for missing persons, cold case, and historic case investigations.     

Use of a commercially available hydrogel as a novel DNA surface sampling tool

A common requirement in the military, law enforcement, and forensic mission space is the need to collect trace samples from surfaces using a method that not only readily captures the sample but also retains its integrity for downstream identification and characterization. Additionally, collecting samples from three-dimensional objects (e.g., shell casings) is a challenge for which there is currently no validated standardized approach. Recently, hydrogels have been shown to have the potential for surface collection of trace bacterial spores, amino acids, and DNA. To test whether these hydrogels can serve as a viable collection medium for sampling DNA from surfaces, we carried out a series of preliminary tests examining collection efficiency and suitability of hydrogel material to recover samples of diluted, dried human DNA on a smooth polycarbonate surface. The recovery of surface DNA using a commercially available hydrogel was examined, and the efficiency compared to samples collected using a standard foam collection swab. DNA collected using the hydrogel and swab methods was then examined using quantitative polymerase chain reaction (qPCR) and short tandem repeat (STR) analysis to determine whether the collection material was compatible with these downstream processes. The hydrogel material used for this study collected the experimental DNA with comparable efficiency to standard collection swabs. In addition, qPCR and STR analyses demonstrated compatibility with the hydrogel collection and extraction process. These data suggest that hydrogels have the potential to be used as sample collection materials and deserve further characterization to elucidate their utility in collection from irregularly shaped, three-dimensional surfaces/materials.     

Reconciling cultural practices and progress: childbirth in Dove,Ghana

Women are forbidden from giving birth within the community in Dove, Ghana because it is against their culture. Such cultural practice is scarce in contemporary societies so studies on the impact of the practice are currently limited in development literature. This article uses key informant interviews and focus group discussion guides to gather data. Findings reveal that the Chief, the Queenmother, and other community members maintain that the practice is not negatively affecting the socio-economic development of Dove as they have strategies to mitigate the practice.     

Comparative Evaluation of Potentially Radiolucent Projectile Components by Radiographs and Computed Tomography

Projectile components that are traditionally radiolucent can be of considerable importance in determination of weapon type and caliber, but they are often missed on evaluation of postmortem radiographs. We hypothesized that these components would be significantly better visualized by evaluation of computed tomography (CT) scans compared to the practice standard of radiography alone. In this project, potentially radiolucent projectile components were both pulled apart and fired, and the radiolucent components were recovered. These components were embedded in blocks of ballistics gelatin and were imaged using both radiography and CT. The scans were evaluated by three blinded, board‐certified radiologists for the presence/absence of projectile components and true‐negative regions in each block. If a radiologist indicated visualization of a projectile component, they were further requested to describe their observation. It was found that traditionally radiolucent projectile components are not significantly more often identified on CT scans than radiography (p < 0.05).
