Describing Coercion in the Courtroom: The Influence of Language and Maltreatment Severity on Jurors' Perceptions of Child Witnesses
Regardless of compliance to coercion by an alleged perpetrator, child maltreatment is abuse in
any form. However, the extent to which coercion is described as an obligation (mandatory
compliance) or permission (optional compliance) is legally relevant. The present investigation
examined how attorneys question children about coercion and how children describe coercion in
courtroom investigations of alleged child sexual abuse, and whether such language influences
jurors’ perceptions of children’s testimony. Study 1 assessed 64 transcripts of children’s
testimonies and revealed that both attorneys and children use coercive language. Problematically,
terms of permission were used when describing sexual abuse, potentially implying compliance
was optional. Study 2 presented 160 adults with transcript excerpts, varied by coercive language
(obligation or permission) and maltreatment type (sexual abuse or punishment). Coercive
language influenced perceptions of coercion and whether the adult was to blame. Maltreatment
type influenced perceptions of severity, credibility, and verdict. Overall, coercive language and
maltreatment type influence perceptions of how the event unfolde
High-flux source system for matter-wave interferometry exploiting tunable interactions
Atom interferometers allow determining inertial effects to high accuracy. Quantum-projection noise as well as systematic effects impose demands on large atomic flux as well as ultralow expansion rates. Here we report on a high-flux source of ultracold atoms with free expansion rates near the Heisenberg limit directly upon release from the trap. Our results are achieved in a time-averaged optical dipole trap and enabled through dynamic tuning of the atomic scattering length across two orders of magnitude interaction strength via magnetic Feshbach resonances. We demonstrate Bose-Einstein condensates with more than 6×104 particles after evaporative cooling for 170 ms and their subsequent release with a minimal expansion energy of 4.5 nK in one direction. Based on our results we estimate the performance of an atom interferometer and compare our source system to a high performance chip trap, as readily available for ultraprecise measurements in microgravity environments
Young Children’s Ability to Describe Intermediate Clothing Placement
Children’s ability to adequately describe clothing placement is essential to evaluating their allegations of sexual abuse. Intermediate clothing placement (partially removed clothing) may be difficult for young children to describe, requiring more detailed explanations to indicate the location of clothing (e.g., the clothes were pulled down to the knees). The current study investigated 172 3- to 6-year-olds’ descriptions of clothing placement when responding to commonly used questions (yes/no, forced-choice, open-choice, where), as well as children’s on-off response tendencies when describing intermediate placement (i.e., labeling the clothing as fully on or off). Results revealed that where questions were superior in eliciting intermediate descriptions, even for the youngest children. Children sometimes exhibited tendencies to describe intermediate placements as “on” or “off,” which varied by question-type and clothing placement. The implications of the findings for interviewing young children about sexual abuse are discussed
Child witnesses productively respond to "How" questions about evaluations but struggle with other "How" questions
Child interviewers are often advised to avoid asking “How” questions, particularly with young children. However, children tend to answer “How” evaluative questions productively (e.g., “How did you feel?”). “How” evaluative questions are phrased as a “How” followed by an auxiliary verb (e.g., “did” or “was”), but so are “How” questions requesting information about method or manner (e.g., “How did he touch you?”), and “How” method/manner questions might be more difficult for children to answer. We examined 458 5- to 17-year-old children questioned about sexual abuse, identified 2485 "How” questions with an auxiliary verb, and classified them as “How” evaluative (n = 886) or “How” method/manner (n = 1599). Across age, children gave more productive answers to “How” evaluative questions than “How” method/manner questions. Although even young children responded appropriately to “How” method/manner questions over 80% of the time, specific types of “How” method/manner questions were particularly difficult, including questions regarding clothing, body positioning, and the nature of touch. Children’s difficulties lie in specific combinations of “How” questions and topics, rather than “How” questions in general
Mental Health of Parents and Life Satisfaction of Children: A Within-Family Analysis of Intergenerational Transmission of Well-Being
This paper addresses the extent to which there is an intergenerational transmission of mental health and subjective well-being within families. Specifically it asks whether parents’ own mental distress influences their child’s life satisfaction, and vice versa. Whilst the evidence on daily contagion of stress and strain between members of the same family is substantial, the evidence on the transmission between parental distress and children’s well-being over a longer period of time is sparse. We tested this idea by examining the within-family transmission of mental distress from parent to child’s life satisfaction, and vice versa, using rich longitudinal data on 1,175 British youths. Results show that parental distress at year t-1 is an important determinant of child’s life satisfaction in the current year. This is true for boys and girls, although boys do not appear to be affected by maternal distress levels. The results also indicated that the child’s own life satisfaction is related with their father’s distress levels in the following year, regardless of the gender of the child. Finally, we examined whether the underlying transmission correlation is due to shared social environment, empathic reactions, or transmission via parent-child interaction
Vitamin D and subsequent all-age and premature mortality: a systematic review
<br>Background:
All-cause mortality in the population < 65 years is 30% higher in Glasgow than in equally deprived Liverpool and Manchester. We investigated a hypothesis that low vitamin D in this population may be associated with premature mortality via a systematic review and meta-analysis.</br>
<br>Methods:
Medline, EMBASE, Web of Science, the Cochrane Library and grey literature sources were searched until February 2012 for relevant studies. Summary statistics were combined in an age-stratified meta-analysis.</br>
<br>Results:
Nine studies were included in the meta-analysis, representing 24,297 participants, 5,324 of whom died during follow-up. The pooled hazard ratio for low compared to high vitamin D demonstrated a significant inverse association (HR 1.19, 95% CI 1.12-1.27) between vitamin D levels and all-cause mortality after adjustment for available confounders. In an age-stratified meta-analysis, the hazard ratio for older participants was 1.25 (95% CI 1.14-1.36) and for younger participants 1.12 (95% CI 1.01-1.24).</br>
<br>Conclusions:
Low vitamin D status is inversely associated with all-cause mortality but the risk is higher amongst older individuals and the relationship is prone to residual confounding. Further studies investigating the association between vitamin D deficiency and all-cause mortality in younger adults with adjustment for all important confounders (or using randomised trials of supplementation) are required to clarify this relationship.</br>
Diabetes prevalence is associated with serum 25-hydroxyvitamin D and 1,25-dihydroxyvitamin D in US middle-aged Caucasian men and women: a cross-sectional analysis within the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial
Hypovitaminosis D may be associated with diabetes, hypertension and CHD. However, because studies examining the associations of all three chronic conditions with circulating 25-hydroxyvitamin D (25(0H)D) and 1,25-dihydroxyvitamin D (1,25(0H)2D) are limited, we examined these associations in the US Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial (n 2465). Caucasian PLCO participants selected as controls in previous nested case-control studies of 25(0H)D and 1,25(0H)2D were included in this analysis. Diabetes, CHD and hypertension prevalence, risk factors for these conditions and intake of vitamin D and Ca were collected from a baseline questionnaire. Results indicated that serum levels of 25(0H)D were low (\u3c50nmol/1) in 29% and very low ( \u3c 37nmol/1) in 11% of subjects. The prevalence of diabetes, hypertension and CHD was 7, 30 and 10%, respectively. After adjustment for confounding by sex, geographical location, educational level, smoking history, BMI, physical activity, total dietary energy and vitamin D and Ca intake, only diabetes was significantly associated with lower 25(0H)D and 1,25(0H)2D levels. Caucasians who had 25(0H)D 2:80nmol/1 were half as likely to have diabetes (OR 0·5 (95% Cl 0·3, 0·9)) compared with those who had 25(0H)D /l. Those in the highest quartile of 1,25(0H)2D (/1) were less than half as likely to have diabetes (OR 0·3 (95% Cl 0·1, 0·7)) than those in the lowest quartile (\u3c 72pmol/l). In conclusion, the independent associations of 25(0H)D and 1,25(0H)2D with diabetes prevalence in a large population are new findings, and thus warrant confirmation in larger, prospective studies
