Between a Rock and a Hard Place: Resident Mothers and the Moral Dilemmas they Face During Custody Disputes

Recent scholarship has critiqued the tendency for separated mothers in custody disputes to be defined as hostile and alienating. Through the presentation of three case studies, drawn from an interview-based study with 21 women, we show how such pejorative constructions only arise when the conflicting gendered moral accountabilities of contemporary motherhood are overlooked. We found that mothers tend to believe that contact with non-resident fathers is generally in a child’s best interests. However, as a result of balancing complex moral obligations for the care of their children, they may raise questions about particular kinds of arrangements for contact with particular fathers. We argue, therefore, that family law practice will lead to better outcomes for children when professionals listen to the history of, and reasons for, mothers’ positions. To enable family law professionals to undertake this task, we offer an alternative interpretive framework for making sense of women’s stories. Should family law professionals make use of this framework, it is likely that they will understand that the positions mothers adopt are often the outcome of the difficult moral dilemmas they encounter in caring for their children, and that the reductive rubric of the ‘hostile mother’ needs to be treated with scepticism.     

Quantifying the Temperature of Maggot Masses and its Relationship to Decomposition

Numerous Calliphoridae species have been observed to form larval aggregations during the feeding stage of development, resulting in localized increases in temperature. This study investigates the relationship between maggot numbers in a mass and heat generation. Single‐species aggregations (Lucilia sericata) of various sizes (50–2500 individuals) were reared in the laboratory at a constant ambient temperature of 22°C. Internal mass temperatures were recorded every 5 min throughout the feeding stage of development. Results showed that mass temperatures increased with mass numbers (p‐value < 0.001), ranging from 2.5 to 14°C above ambient. A minimum mass size of 1200 produced overall temperatures that were significantly warmer than ambient, diverging away from 22°C after c. 26 h. These results indicate that the microclimate of a mass has the potential to differ significantly from ambient, which may be influencing larval development rates and should therefore be factored into mPMI estimates to increase accuracy.     

Sexual Dimorphism of the First Rib: A Comparative Approach Using Metric and Geometric Morphometric Analyses

This research investigated the sexual dimorphism of the first human rib using geometric morphometric and metric approaches on a sample of 285 specimens containing European Americans and African Americans from the Hamann‐Todd collection. Metric measurements were investigated for sexual dimorphism and ancestral differences using univariate statistics. Four type II landmarks and 40 sliding semi‐landmarks were placed outlining the dorsal and ventral curvatures of the ribs. Landmark data were processed using Generalized Procrustes Analyses with Procrustes distance sliding, and the subsequent coordinates were investigated for sexual dimorphism and ancestral differences using Procrustes ANOVAs. Both geometric morphometric and metric data were analyzed using cross‐validated discriminant function analyses to test the hypothesis that variables from both approaches can be combined to increase sex classification rate. European Americans had sex correctly classified as high as 88.05% and African Americans as high as 70.86% using a combination of metric and geometric morphometric variables.     

Feminist research and the use of drama

This paper looks at the question of a feminist methodology and argues that the researcher and her aims are crucial, rather than the particular techniques she may use. A broader definition of ‘methodology’ is suggested, describing the process or feminist approach to the research, which starts from women's experience and can include qualitative or quantitative methods. A research project using drama with adolescent girls is analysed to see how far drama can be seen as a qualitative feminist method. It is argued that drama cannot be inherently feminist, but in this case was used in a feminist way because of the researcher's feminist approach.     

A Comparison of Thresholding Methods for Forensic Reconstruction Studies Using Fluorescent Powder Proxies for Trace Materials

Image segmentation is a fundamental precursor to quantitative image analysis. At present, no standardised methodology exists for segmenting images of fluorescent proxies for trace evidence. Experiments evaluated (i) whether manual segmentation is reproducible within and between examiners (with three participants repeatedly tracing three images) (ii) whether manually defining a threshold level offers accurate and reproducible results (with 20 examiners segmenting 10 images), and (iii) whether a global thresholding algorithm might perform with similar accuracy, while offering improved reproducibility and efficiency (16 algorithms tested). Statistically significant differences were seen between examiners’ traced outputs. Manually thresholding produced good accuracy on average (within ±1% of the expected values), but poor reproducibility (with multiple outliers). Three algorithms (Yen, MaxEntropy, and RenyiEntropy) offered similar accuracy, with improved reproducibility and efficiency. Together, these findings suggest that appropriate algorithms could perform thresholding tasks as part of a robust workflow for reconstruction studies employing fluorescent proxies for trace evidence.
