Ancestry and BMI Influences on Facial Soft Tissue Depths for A Cohort of Chinese and Caucasoid Women in Dunedin,New Zealand

This study measured and assessed facial soft tissue depths (FSTDs) in adult female Chinese and New Zealand (NZ) Europeans (Caucasoids). Ultrasound was used to obtain depths at nine landmarks on 108 healthy subjects (51 Chinese, 57 NZ European), erect positioned, of same age group (18–29 years). Height and weight were also recorded. Statistical analysis focused on comparison of tissue depth between the two ancestry groups and the influence of Body Mass Index (BMI) (kg/m²). Results showed mean depth differences at Supra M2 and Infra M2 landmarks significantly greater for Chinese than Caucasoid women for all three BMI Classes (BMI <20, 20 ≤ BMI < 25, 25 ≤ BMI < 30), even BMI <20. For both groups BMI positively correlated with FSTD values at all landmarks except Labrale superius. This study enabled ancestry and BMI influence on FSTDs to be observed and compared for two distinct groups. Results add to knowledge about facial tissue depth variation.     

Position Effect on Facial Soft Tissue Depths: A Sonographic Investigation

The head is positioned erect for an approximation; yet most facial soft tissue depths (FSTD) used are measured from supine subjects. Depth difference might be significant, but there is a paucity of data to verify. This study compared erect and supine values for 17 landmarks from 30 healthy New Zealand (European population affinity) women (18–30 or 40–55 years) in erect then supine positions. Height, weight, and sonographic FSTD data, totaling 1020 measurements, were obtained. Three midline and seven averaged bilateral values were compared using ANOVA, p values, and Pearson's correlations. Correlative strength of age and body mass index, BMI (kg/m²), was determined by values. Results showed averaged erect and supine differences were significant for four of ten FSTDs. Between individuals, difference was various and not unidirectional. In conclusion, depth differences were observed but not all significant or unidirectional, BMI significantly influenced nine FSTD values, but age group did not.     

Childhood Sexual Abuse and Intimate Partner Violence among Women in Methadone Treatment: A Direct or Mediated Relationship?

Women in substance use treatment report rates of childhood sexual abuse and intimate partner violence that far exceed those reported by women in the general population. Previous research with nonrandom samples of women in substance use treatment suggests that there is a statistically significant relationship between childhood sexual abuse and intimate partner violence; however, little is known about the mechanisms of risk between these two public health concerns among this population of women. To address this gap in knowledge and to inform intervention strategies, this study examined direct and mediated relationships between childhood sexual abuse and intimate partner violence risk among a random sample of 416 women in methadone treatment. In addition to high rates of childhood sexual abuse (57.9%), intimate partner violence (lifetime prevalence, 89.7%; 6-month prevalence, 78.4%), posttraumatic stress disorder (PTSD, 28.6%), and global psychological distress (19.5%), findings suggest that the relationship between childhood sexual abuse and intimate partner violence is mediated by mental health problems and that women experiencing PTSD or global psychological distress are 2.7 and 2.4 times more likely to experience intimate partner violence than women without such experiences, respectively. Although not a mediator in this relationship, financial independence reduced women's risk of partner violence by two-thirds. The paper includes discussion of social learning and stress and coping theories to explicate the findings and to inform intervention strategies. This study is based, in part, on the first author's dissertation. A previous version of this paper was presented at the Society for Social Work and Research Annual Conference held in January 2005 in New Orleans, Louisiana.

Perceived positive aspects of intimate relationships among abused women in methadone maintenance treatment programs (MMTP)

This study examines the positive aspects of intimate relationships perceived by drug-involved women victims of intimate partner violence (IPV). The article examines the association of psychological distress, childhood abuse, and severity of IPV with the different positive aspects the women indicated. Most analyses were conducted on a subsample of 149 women in methadone maintenance treatment who intended to continue their relationship with their abusive partner. The women most frequently valued fulfillment of the role of an intimate partner such as "he takes care of me, loves me, makes me laugh" (29.7%). Fewer than one tenth of the women valued their partners' role as economic provider; however, these women reported more physical IPV. Women intending to continue the relationship (more than two thirds of the participants) reported less physical or sexual IPV and experienced less psychological distress. Policy and practice implications are discussed.     

Drug Abuse and Partner Violence among Women in Methadone Treatment

This study aims to (1) describe rates of lifetime and current partner abuse among women on methadone; (2) examine the relationship between partner violence and demographics, substance abuse, and drug risk behaviors; and (3) explore the association between a victim's current use of crack/cocaine, heroin, marijuana, and drug risk behavior after controlling for demographics, household composition, history of victimization and sex trading. Approximately three-fourths of the women ever experienced physical, sexual, or life-threatening abuse and slightly less than one-third experienced at least one type of abuse during the previous year. A history of childhood victimization was reported by more than half of the women and one-third witnessed her mother being abused. Risk of partner violence was associated with victim's current drug and alcohol use, visiting shooting galleries, and living with someone with drug or alcohol problems. The study discusses the implications of the findings for research and intervention.     

Voters,dictators, and peons: expressive voting and pivotality

Why do the poor vote against redistribution? We examine one explanation experimentally, namely that individuals gain direct expressive utility from voting in accordance with their ideology and understand that they are unlikely to be pivotal; hence, their expressive utility, even if arbitrarily small, determines their voting behavior. In contrast with a basic prediction of this model, we find that the probability of being pivotal does not affect the impact of monetary interest on whether a subject votes for redistribution.
