Racial Differences Between African and White Americans in the Presentation of Borderline Personality Disorder

Borderline personality disorder (BPD) is commonly thought of as a disorder of White females. Despite evidence indicating similar prevalence rates across races and genders, no study has examined the experience of BPD among ethnic minorities and how this differs from Whites. The affective and behavioral symptoms of BPD were studied in 17 African Americans and 27 White Americans with the disorder. Results indicated that African Americans experience greater affective intensity and emotional dysregulation, fewer self-harming behaviors, and more thoughts of interpersonal aggression than Whites. Differences in affective symptoms were accounted for by group differences in substance use and receipt of inpatient services, whereas differences in behavioral symptomatology persisted after adjusting for potential confounders. These findings suggest that not only is BPD not a disorder exclusive to White females, but that the experience of the disorder may differ substantially across races. Implications for future research and directions for developing culturally relevant treatments are discussed.     

An online estimation scheme for a Hull–White model with HMM-driven parameters

This paper considers the implementation of a mean-reverting interest rate model with Markov-modulated parameters. Hidden Markov model filtering techniques in Elliott (1994, Automatica, 30:1399–1408) and Elliott et al. (1995, Hidden Markov Models: Estimation and Control. Springer, New York) are employed to obtain optimal estimates of the model parameters via recursive filters of auxiliary quantities of the observation process. Algorithms are developed and implemented on a financial dataset of 30-day Canadian Treasury bill yields. We also provide standard errors for the model parameter estimates. Our analysis shows that within the dataset and period studied, a model with two regimes is sufficient to describe the interest rate dynamics on the basis of very small prediction errors and the Akaike information criterion.     

Lerne die Regeln um sie zu verändern! Die Rolle der Organisationslogik in Veränderungsprozessen

In this article we introduce the concept of the firm’s organizational logic and how it influences organizational change processes. Characteristics and the essence of the organizational logic are explained and then illustrated by mean of a real-world case. Depending on the level of organizational change – whether it leads to single-loop, double-loop or deutero learning – we provide different implications for change agents to make use of the organizational logic to steer organizational change successfully.     

Young Adult Migration from a Northern Plains Indian Reservation: Who Stays and Who Leaves

We evaluated how ambitions, community ties, monetary sufficiency, employment, and alcohol consumption related to whether young American Indian adults had moved from their Northern Plains reservation. Of 518 Northern Plains reservation residents in 1993, we located 472 in 2003–2005 and found that 89 lived more than a four-hour drive from the reservation. Coding the 472 as to whether they had stayed on/near the reservation or moved away, we ran logistic regressions on data they reported in 1996 to determine which demographic and attitudinal variables were associated with having moved. We found ambitions and goals were more associated with moving away than were ties to the community, which in turn were more related than monetary and personal characteristics that promote independence and prosperity. The more importance they placed on getting a good education or carrying on the tribe’s traditions, the more likely they were to have moved away. We found too that the odds of moving away decreased with greater alcohol consumption. Tribal council members and college administrators therefore may wish to promote policies that increase opportunities for young adults to achieve higher education goals while remaining on reservation to carry on tribal traditions. Benefits may also come from encouraging and assisting reservation members studying off-reservation to return after completing their education. These findings would argue too for greater investment in alcohol services for reservation-dwelling populations.     

Development of Ego‐resiliency: Relations to Observed Parenting and Polymorphisms in the Serotonin Transporter Gene During Early Childhood

We used observed parenting behaviors, along with genetic variants and haplotypes of the serotonin transporter gene (SLC6A4), as predictors of children's ego‐resiliency during early childhood (N = 153). The quality of mothers' parenting was observed at 18 months of age, and mothers' reports of ego‐resiliency were collected at six time points from 18 to 84 months. Genetic data were collected at 72 months. Observed parenting was positively associated with initial levels of children's ego‐resiliency. Furthermore, although individual genetic variants of the serotonin transporter gene (LPR, STin2) were not associated with ego‐resiliency, the S10 haplotype (that combines information from these two variants) was negatively associated with initial levels of ego‐resiliency. Both parenting and serotonin genetic variation uniquely predicted children's ego‐resiliency, suggesting an additive effect of genetic and parental factors.

Cumulative Risk for Early Sexual Initiation Among American Indian Youth: A Discrete‐Time Survival Analysis

Approximately 3 million teens are diagnosed with a sexually transmitted disease (STD) annually; STDs rates for American Indian young adults are among the highest of any racial/ethnic group. An important risk factor for STDs is early initiation of sex. In this study, we examined risk for early initiation with 474 American Indian youth ages 14–18, using 11 risk factors from three developmentally important microsystems (family, school, peers) along with several individual characteristics; a cumulative risk index was also calculated. Discrete‐time survival analyses showed that predictors of early initiation differed by gender. For young men, younger initiation of sex was predicted by lower grades, liking school less, having peers with less prosocial attitudes, a greater likelihood of having used alcohol or drugs at first sex, and having higher sensation‐seeking. For young women, earlier initiation was related to having mothers who had their first child at an early age and who had less formal education, to having parents who had divorced, dropping out of high school, using alcohol/drugs at first sex, and higher sensation‐seeking. Higher cumulative risk was associated with elevated risk of sexual initiation, although the degree of added risk varied with age for women. Cumulative risk deserves broader attention in understanding the early initiation of sexual intercourse.     

The Association of Couples’ Relationship Status and Quality With Breastfeeding Initiation

Using data from the Fragile Families and Child Wellbeing Survey (N= 3,567), we examine the links between relationship status, relationship quality, and race and ethnicity in breastfeeding initiation. We consider four relationship types: married, cohabiting, romantically involved but not cohabiting (termed visiting), and nonromantically involved mothers. We find that even after adjusting for a wide range of sociodemographic factors, married mothers were more likely to breastfeed than unmarried mothers and that racial and ethnic differences in breastfeeding do not result from differences in marriage rates. Among unwed mothers, paternal provision of money or other assistance during pregnancy decreases the likelihood of breastfeeding. We conclude that relationship status, above and beyond demographic characteristics, is an important correlate of breastfeeding.     

Understanding Vulnerability: From Categories to Experiences of Young Congolese People in Uganda

This article problematises the ‘vulnerables’ category that the United Nations High Commissioner for Refugees applies to groups of refugees. Drawing on 9 months’ qualitative research with young Congolese refugees in Uganda, it presents research subjects’ self‐identification and lived realities that do not correspond to the homogenous, fixed ‘vulnerables’ ideal. Moreover, it argues that the ‘vulnerables’ categorisation approach can provoke a number of counter‐productive effects, including a focus on symptoms rather than causes, inflated numbers of ‘vulnerables’ and undermining indigenous support structures. An alternative approach that interrogates and addresses the contextual and relational aspects of vulnerability is proposed.
