Total Body Mass Estimation from Anthropometric Measurements in Modern Young Adult U.S. Populations with Healthy Body Fat Percentages (NHANES III)

This study presents a method by which to estimate total body mass in modern young adult U.S. populations who self‐identified as non‐Hispanic U.S. White, non‐Hispanic U.S. Black, and Mexican American with anthropometric measurements from the Third National Health and Nutrition Examination Survey (NHANES III) 1988–1994 dataset (N = 2532). Correlations of stature and bi‐iliac breadth with total body mass were stronger among males (r = 0.717–0.774) than among females (r = 0.549–0.661), yet these results were more accurate assessments of total body mass than existing techniques. This study also examined additional anthropometric measurements to estimate total body mass using an information‐theoretic approach demonstrating that some error in the stature–bi‐iliac breadth method is attributed to a nonsupported model with multimodel inference. The limitations of the current total body mass technique are discussed as well as the need for future studies to validate the method.     

Bacterial Cross‐contamination Potential Associated with Contaminated Currency

Previous studies have shown a significant amount of contaminants on paper currencies. It is important to study the transfer of microorganisms between paper currencies to determine whether it meets the level of a human health threat. This cross‐contamination potential was analyzed by seeding new US 1‐dollar bills with Bacillus thuringiensis, and pressing or rubbing them against clean currency to determine the amount of bacteria transfer to the unseeded currency. The transferred amount of bacteria was recovered, plated, incubated, and the colony‐forming units were quantified. Among the recovery methods tested, the most efficient method, vortexing for 10 min with a recovery efficiency of 40 ± 8.1%, was used in this analysis. The resulting transfer rates were 4.8%, 8.6%, and 14.3% when pressed for 24 h, 72 h, and rubbed together, respectively. These transferred amounts of bacteria are significant and have the potential to spread infectious diseases.     

Beyond Taphonomy: Exploring Craniometric Variation Among Anatomical Material

Anatomical crania are occasionally encountered in forensic anthropology laboratories when that material is mistaken for forensically significant human remains. Using craniometric analyses and statistical measures of sample homogeneity, we determine whether anatomical material can be described as a single, homogenous group or as a diverse mix of populations. Twenty‐one interlandmark distances were collected from 85 anatomical preparations. Distance measures were calculated between all pairs using a pooled within‐sample variance/covariance matrix and then subjected to a Defrise‐Gussenhoven test between each paired distance to test whether each pair was drawn randomly from the same population. In the Defrise‐Gussenhoven analysis, twenty‐two percent (n = 66) of the 300 pairwise combinations were significant at the 0.05 level or below. The level of homogeneity suggests a majority of that material originated from the subcontinent of India or West Asia. Therefore, anatomical material can be viewed as a moderately homogenous group, but with a shared taphonomic history.     

Vertical Lip Position and Thickness in Facial Reconstruction: A Validation of Commonly Used Methods for Predicting the Position and Size of Lips

This study examined several methods used to estimate oral fissure position, lip margin position, and lip thickness recommended by Angel, George, Lebedinskaya, Taylor, Wilkinson et al., Balueva and Veselovskaya. A sample of 86 lateral head cephalograms of adult subjects from central Europe were measured and the actual and predicted dimensions were compared. The best estimation for oral fissure position was “opposite the lower ¾ mark of maxillary incisors” (error of 1.3 mm). Upper lip margin was predicted best by “upper ¼ mark of maxillary incisors” (error of 1.7 mm), and lower lip margin by “cementum‐enamel junction of mandibular incisors” (error of 2.3 mm). The regression equations of Wilkinson et al. displayed least error (1.3 mm and 1.8 mm, respectively) for upper and lower lip thickness, and method of George (error of 3.4 mm) for total lip thickness.     

Catching Them Before Too Much Damage is Done: Early Intervention with Resistance‐Refusal Dynamics

Children often need help before their parents are ready to stop fighting. Children at the center of high‐conflict disputes, particularly those who resist contact with a parent, face extraordinary risks of maladjustment. Years of investigation and litigation may precede any meaningful attempt at intervention, based on the questionable belief that all elements of causality (or blame) must be established before any effective treatment can occur. Children's functioning may continue to deteriorate during this time, undermining their future adjustment and reducing the chance of successful intervention later. We illustrate the application of the coping‐focused, multisystemic Child Centered Conjoint Therapy model to assisting these families. Methods to assist children without compromising external investigations are discussed.     

Co‐parenting in a Highly Conflicted Separation/Divorce: Learning about Parents and their Experiences of Parenting Coordination,Legal, and Mental Health Interventions

Sixty high‐conflict separated/divorced co‐parents completed surveys investigating characteristics and dynamics (narcissism, empathy, conflict) that were examined in relation to co‐parenting style and parents' experiences of parenting coordination, legal, and mental health interventions. Study findings for this sample did not support common notions found in the literatures on parenting coordination and high‐conflict divorce that suggest these parents are often narcissistic or low in empathy. Findings pertaining to all high‐conflict participant experiences revealed the presence of common elements across aspects of practitioners and interventions with which they were both satisfied and dissatisfied.     

Convenient and Inconvenient Truths in Family Law: Preventing Scholar‐Advocacy Bias in the Use of Social Science Research for Public Policy

This is the second of two articles on the risks of advocacy bias in the reporting of research findings when boundaries are blurred between social science research and advocacy in the pursuit of public policy. In the first article we identify common ways in which social science researchers and reviewers of research—wittingly or unwittingly—can become advocates for ideological positions and social policies at the expense of being balanced reporters of research evidence. The first article discusses the difference between truth in social science and truth in law and identifies a range of scholar‐advocacy strategies that bias research evidence, illustrated by recent debates about overnight parenting of infants and toddlers. In this second article we show how biased research evidence by scholar advocates results in increased confusion and controversy that diminishes the credibility of all parties and stalemates progress in the field, using a case illustration of intimate partner violence in family court. We also show how adherence to scientific methods prevents the misuse of research and suggest a number of collaborative, integrative measures that can help transcend the adversarial stalemate. In a look to the future we consider some unbiased, standardized ways of assessing the strength and generalizability of research evidence.
