    Two to tango: A dyadic analysis of links between borderline personality traits and intimate partner violence

    Get PDF
    Although research has shown links between borderline personality and intimate partner violence (IPV), few studies have examined how each partner’s personality traits may influence the other’s behavior(Hines, 2008). This study incorporated dimensional assessments of borderline personality organization (BPO) in both partners into a dyadic model that examined associations with IPV. In a community sample of 109 couples, Actor-Partner Interdependence Modeling was used to examine links between BPO traits in each partner and victimization and perpetration of IPV. Men’s level of BPO traits was associated with more IPV towards and more victimization by their partners. Women’s level of BPO traits was associated with their victimization only. This study is unique in examining links between BPO and IPV in couples using analyses that account for the interdependence of these variables in dyads

    Previously Unidentified Changes in Renal Cell Carcinoma Gene Expression Identified by Parametric Analysis of Microarray Data

    BACKGROUND. Renal cell carcinoma is a common malignancy that often presents as a metastatic-disease for which there are no effective treatments. To gain insights into the mechanism of renal cell carcinogenesis, a number of genome-wide expression profiling studies have been performed. Surprisingly, there is very poor agreement among these studies as to which genes are differentially regulated. To better understand this lack of agreement we profiled renal cell tumor gene expression using genome-wide microarrays (45,000 probe sets) and compare our analysis to previous microarray studies. METHODS. We hybridized total RNA isolated from renal cell tumors and adjacent normal tissue to Affymetrix U133A and U133B arrays. We removed samples with technical defects and removed probesets that failed to exhibit sequence-specific hybridization in any of the samples. We detected differential gene expression in the resulting dataset with parametric methods and identified keywords that are overrepresented in the differentially expressed genes with the Fisher-exact test. RESULTS. We identify 1,234 genes that are more than three-fold changed in renal tumors by t-test, 800 of which have not been previously reported to be altered in renal cell tumors. Of the only 37 genes that have been identified as being differentially expressed in three or more of five previous microarray studies of renal tumor gene expression, our analysis finds 33 of these genes (89%). A key to the sensitivity and power of our analysis is filtering out defective samples and genes that are not reliably detected. CONCLUSIONS. The widespread use of sample-wise voting schemes for detecting differential expression that do not control for false positives likely account for the poor overlap among previous studies. Among the many genes we identified using parametric methods that were not previously reported as being differentially expressed in renal cell tumors are several oncogenes and tumor suppressor genes that likely play important roles in renal cell carcinogenesis. This highlights the need for rigorous statistical approaches in microarray studies.National Institutes of Healt

    Inelastic scattering of light by a cold trapped atom: Effects of the quantum center-of-mass motion

    Get PDF
    The light scattered by a cold trapped ion, which is in the stationary state of laser cooling, presents features due to the mechanical effects of atom-photon interaction. These features appear as additional peaks (sidebands) in the spectrum of resonance fluorescence. Among these sidebands the literature has discussed the Stokes and anti-Stokes components, namely the sidebands of the elastic peak. In this manuscript we show that the motion also gives rise to sidebands of the inelastic peaks. These are not always visible, but, as we show, can be measured in parameter regimes which are experimentally accessible.Comment: 10 pages, 4 figures, submitted to Phys. Rev.

    Eye of the Beholder: The individual and dyadic contributions of empathic accuracy and perceived empathic effort to relationship satisfaction

    Get PDF
    This study examined links between two distinct facets of empathy – empathic accuracy and perceived empathic effort – and one’s own and one’s partner’s relationship satisfaction. Using a video recall procedure, participants (N = 156 couples in committed relationships) reported on their own emotions and their perceptions of partners’ emotions and partners’ empathic intentions during moments of high affect in laboratory-based discussions of upsetting events. Partners’ data were correlated as a measure of how accurately they were able to read what the other was feeling and to what degree they felt the other was trying to be empathic at those moments. The perception of empathic effort by one’s partner was more strongly linked with both men’s and women’s relationship satisfaction than empathic accuracy. Men’s relationship satisfaction was related to the ability to read their partners’ positive emotions accurately, whereas women’s relationship satisfaction was related to their partners’ ability to read women’s negative emotions accurately. Women’s ability to read their husbands’ negative emotions was positively linked to both men’s and women’s relationship satisfaction. Findings suggest that the perception of a partner’s empathic effort – as distinct from empathic accuracy – is uniquely informative in understanding how partners may derive relationship satisfaction from empathic processes. When working with couples in treatment, heightening partners’ perceptions of each other’s empathic effort, and helping partners learn to demonstrate effort, may represent particularly powerful opportunities for improving satisfaction in relationships

    Sources of somatization: Exploring the roles of insecurity in relationships and styles of anger experience and expression

    Get PDF
    Research has shown strong connections between insecure attachment in close relationships and somatization. In addition, studies have demonstrated connections between somatic symptoms and anger experience and expression. In this study, we integrate perspectives from these two literatures by testing the hypothesis that proneness to anger and suppression of anger mediate the link between insecurity in relationships and somatization. Between 2000 and 2003, a community-based sample of 101 couples in a large U.S. city completed self-report measures, including the Somatic Symptom Inventory, the Relationship Scales Questionnaire, the Multidimensional Anger Inventory, the Revised Conflict Tactics Scale, and the Beck Depression Inventory. Controlling for age, income, and recent intimate partner violence, analyses showed that the link between insecure attachment and somatization was partially mediated by anger proneness for men and by anger suppression for women. Findings are consistent with the hypothesis that men who are insecurely attached are more prone to experience anger that in turn fosters somatization. For women, findings suggest that insecure attachment may influence adult levels of somatization by fostering suppression of anger expression. Specific clinical interventions that help patients manage and express angry feelings more adaptively may reduce insecurely attached individuals’ vulnerability to medically unexplained somatic symptoms

    Security of attachment to spouses in late life: Concurrent and prospective links with cognitive and emotional wellbeing

    Get PDF
    Social ties are powerful predictors of late-life health and well-being. Although many adults maintain intimate partnerships into late life, little is known about mental models of attachment to spouses and how they influence aging. A total of 81 elderly heterosexual couples (162 individuals) were interviewed to examine the structure of attachment security to their partners; respondents also completed measures of cognition and well-being concurrently and 2.5 years later. Factor analysis revealed a single factor for security of attachment. Higher security was linked concurrently with greater marital satisfaction, fewer depressive symptoms, better mood, and less frequent marital conflicts. Greater security predicted lower levels of negative affect, less depression, and greater life satisfaction 2.5 years later. For women, greater security predicted better memory 2.5 years later and attenuated the link between frequency of marital conflict and memory deficits. Late in life, mental models of attachment to partners are linked to well-being concurrently and over time
