A Bayesian Approach for Multiple Response Surface Optimization in the Presence of Noise Variables

An approach for the multiple response robust parameter design problem based on a methodology by Peterson (2000) is presented. The approach is Bayesian, and consists of maximizing the posterior predictive probability that the process satisfies a set of constraints on the responses. In order to find a solution robust to variation in the noise variables, the predictive density is integrated not only with respect to the response variables but also with respect to the assumed distribution of the noise variables. The maximization problem involves repeated Monte Carlo integrations, and two different methods to solve it are evaluated. A Matlab code was written that rapidly finds an optimal (robust) solution in case it exists. Two examples taken from the literature are used to illustrate the proposed method.     

Cultural competence in the assessment of poor Mexican families in the rural southeastern United States

Increasing numbers of poor Mexican immigrant families are settling in the rural southeastern United States. Most of these families are from isolated agrarian communities in Mexico and are headed by unskilled laborers or displaced farm workers with little education. Child welfare workers and other service providers in rural communities may be poorly prepared to address the needs of this population. This article provides an overview of the cultural, social, and family dynamics of first generation, working class Mexicans to promote cultural competency among helping professionals. An ecological perspective is used to examine the strengths that poor Mexicans bring from their culture of origin, stresses of the migratory experience and ongoing adaptation, shifts that may occur in family structure and functioning, disruptions in the family life cycle, the role of social supports in family adaptation, and effect of institutional discrimination on family well-being. Suggestions also are made for essential components of adequate in-service education.     

Marital Conflict in the Context of Parental Depressive Symptoms: Implications for the Development of Children's Adjustment Problems

Relations among parental depressive symptoms, overt and covert marital conflict, and child internalizing and externalizing symptoms were examined in a community sample of 235 couples and their children. Families were assessed once yearly for three years, starting when children were in kindergarten. Parents completed measures of depressive symptoms and children's internalizing and externalizing symptoms. Behavioral observations of marital conflict behaviors (insult, threat, pursuit, and defensiveness) and self report of covert negativity (feeling worry, sorry, worthless, and helpless) were assessed based on problem-solving interactions. Results indicated that fathers' greater covert negativity and mothers' overt destructive conflict behaviors served as intervening variables in the link between fathers' depressive symptoms and child internalizing symptoms, with modest support for the pathway through fathers' covert negativity found even after controlling for earlier levels of constructs. These findings support the role of marital conflict in the impact of fathers' depressive symptoms on child internalizing symptoms.     

Maternal Talk About Mental States and the Emergence of Joint Visual Attention

Twenty‐four infants were tested monthly for gaze and point following between 9 and 15 months of age and mother‐infant free play sessions were also conducted at 9, 12, and 15 months (Carpenter, Nagell, & Tomasello, 1998). Using this data set, this study explored relations between maternal talk about mental states during mothers' free play with their infants and the emergence of joint visual attention in infants. Contrary to hypothesis, mothers' comments about their infants' perceptual states significantly declined after their infants began to engage in joint visual attention. Comments about other mental states did not change relative to acquisition of joint visual attention skill. We speculate that after infants begin to reliably follow gaze and points, mothers may switch the focus of their conversation from their infants' visual behavior and experiences to the object of their mutual attention.     

Trauma-informed care and elder abuse: a synergistic alliance

ABSTRACT

Elder abuse is a global systemic problem in which one or more traumatic or stressful life experiences directly affect older adults, their families, and communities. Despite its devastating impact, the understanding of—and response to—elder abuse has rarely been explored through a trauma-informed lens. Despite the prevalence of traumatic and stressful life experiences, research and practice are just beginning to target the intersection of elder abuse and life course trauma. This article demonstrates how knowledge about the causes, consequences, and responses to elder abuse can be integrated with the principles of trauma-informed care to improve agency and community responses to preventing or intervening with elder abuse and neglect. In order to address the ongoing problems with detection and treatment of elder abuse, we assert that instilling trauma and elder abuse informed care in organizational services and policies forms a synergistic alliance and would address many of these concerns.     

Conceptualizing the “Wantedness” of Women's Consensual and Nonconsensual Sexual Experiences: Implications for How Women Label Their Experiences With Rape

Sex is often conceptualized either as wanted and consensual or as unwanted and nonconsensual, reflecting an implicit model of wanting that is unidimensional and dichotomous and that conflates wanting and consenting. This study has three objectives: developing a multidimensional model for conceptualizing the wantedness of a sexual act, using this model to compare women's experiences with rape and consensual sex, and assessing whether wantedness is related to rape acknowledgment. Participants were college women who described their experiences with rape (n = 77) or consensual sexual intercourse (n = 87). Results supported a multidimensional model of sexual wanting and a wanting—consenting distinction. Compared with acknowledged rape victims, unacknowledged rape victims reported wanting the sexual intercourse more despite not having consented.     

Field Placements in For-Profit Organizations

The recent explosion of proprietary social services suggests that growing numbers of social work students may be placed for field work in organizations whose primary goal is the realization of profits. Information on the extent to which social work programs collaborate with proprietary agencies for field education purposes is unavailable. This article describes the results of a national survey to determine the use patterns and policies of master of social work programs regarding field placements in for-profit settings. Findings indicate that social work education is incorporating proprietary sites for field training at an unparalleled rate. Proprietary sites used most often are hospitals, nursing homes, and outpatient health care agencies. Furthermore, the study links different policy positions on for-profit placements to geographical location. The author suggests, among other recommendations, that programs provide positive role models to help students apply professional values and ethics to problems resulting from proprietary influence upon practice.     

Perceived Admiration and Transition to Parenthood for Black and White Married Couples

Perceived admiration was examined in this study as a mediator of marital quality and transition to parenthood among Black American and White American couples. Positive and negative dimensions of marital quality were assessed for husbands (n = 148) and wives (n = 155) during their 1st and 3rd years of marriage in a large-scale survey. Findings revealed that transitioning Black American husbands reported lower marital tension than transitioning White American husbands. Perceived admiration mediated the link between transition to parenthood and marital well-being for wives, and between transition to parenthood and marital tension for husbands. Results suggest that perceived admiration plays a critical role in understanding the transition to parenthood, regardless of race. Insights are offered for practitioners who provide relationship or parental counseling and education to couples during the transition to parenthood.
