How narcissistic self-construction sabotages their relationships: Accuracy and bias in partner perception

Trapped by their superordinate goal to maintain a grandiose self, narcissists navigate their relationships wishing to re-assure themselves of their specialness and superiority, using strategies bound to fail. Dyadic analyses of diary data (14 days, 83 couples) showed that narcissists focus on their partners’ shortcomings, becoming experts at detecting negative forms of support, while simultaneously minimizing their partner’s positive intentions. Partners of narcissists, in contrast, appear to have a positive bias in ongoing relationships and seem to compensate for some of the narcissists’ shortcomings. Narcissists’ focus on their own selfconstruction purposes also extends to their parenting roles. In a retrospective study, narcissistic mothers were found to demand superior performance, desiring to show-off their child, yet concurrently attributing their child’s success to themselves. They also exercise psychological control and role-reversal, requiring the child to cater to their needs, and to admire them, while simultaneously oblivious to their child’s needs and desires.

Tracing reinforcement through asymmetrical partner preference in the European common vole Microtus arvalis

Background The mechanistic basis of speciation and in particular the contribution of behaviour to the completion of the speciation process is often contentious. Contact zones between related taxa provide a situation where selection against hybridization might reinforce separation by behavioural mechanisms, which could ultimately fully isolate the taxa. One of the most abundant European mammals, the common vole Microtus arvalis, forms multiple natural hybrid zones where rapidly diverging evolutionary lineages meet in secondary contact. Very narrow zones of hybridization spanning only a few kilometres and sex-specific gene flow patterns indicate reduced fitness of natural hybrids and incipient speciation between some of the evolutionary lineages. In this study, we examined the contribution of behavioural mechanisms to the speciation process in these rodents by fine-mapping allopatric and parapatric populations in the hybrid zone between the Western and Central lineages and experimental testing of the partner preferences of wild, pure-bred and hybrid female common voles. Results Genetic analysis based on microsatellite markers revealed the presence of multiple parapatric and largely non-admixed populations at distances of about 10 km at the edge of the area of natural hybridization between the Western and Central lineages. Wild females from Western parapatric populations and lab-born F1 hybrids preferred males from the Western lineage whereas wild females of Central parapatric origin showed no measurable preference. Furthermore, wild and lab-born females from allopatric populations of the Western or Central lineages showed no detectable preference for males from either lineage. Conclusions The detected partner preferences are consistent with asymmetrical reinforcement of pre-mating reproductive isolation mechanisms in the European common vole and with earlier results suggesting that hybridization is more detrimental to the Western lineage. As a consequence, these differences in behaviour might contribute to a further geographical stabilization of this moving hybrid zone. Such behavioural processes could also provide a mechanistic perspective for frequently-detected asymmetrical introgression patterns in the largely allopatrically diversifying Microtus genus and other rapidly speciating rodents.

Sprachloyalität(en)? Sprach-Beziehungen und Sprachweitergabe als Formen von Mehrsprachigkeit. Das Beispiel russischsprachiger Partner/innen in zweisprachig-binationalen Paaren und Familien in der französischsprachigen Schweiz

Die Dissertation betrachtet herkömmliche Untersuchungen zum Thema Sprachloyalität bzw. Spracherhalt kritisch und eröffnet neue Perspektiven auf damit zusammenhängende Fragestellungen. Anstelle des meist gewählten, exklusiven Fokus auf die Beziehung zur (einzigen) Muttersprache und deren intergenerationellen Weitergabe, wird hier vorgeschlagen, Sprachbeziehungen und Sprachweitergabe als Formen von Mehrsprachigkeit zu untersuchen. Es soll dabei den theoretischen und methodologischen Herausforderungen begegnet werden, Sprachbeziehungen und Sprachweitergabe als Prozesse in ihren zeitlichen, räumlichen und sozialen Dimensionen anzugehen und im Spannungsfeld gesellschaftlicher und individueller Vorstellungen und Praktiken einzubetten. In linguistisch-ethnographischer Herangehensweise werden dazu sprachbiografische Interviews und unterschiedliche Interaktionssituationen aus dem Alltag von binationalen, russisch-französischsprachigen Paaren und Familien in der französischsprachigen Schweiz im Hinblick auf Sprachideologien, narrative Identität und Sprachsozialisation analysiert. Der Fokus liegt dabei auf der Bedeutung der einzelnen Sprachen des individuellen Sprachenrepertoires für die russischsprachigen PartnerInnen (Sprachbeziehungen) und der Weitergabe des Russischen an die Kinder. Die Dissertation stellt somit auch eine der wenigen Arbeiten dar, welche das Thema des Spracherhalts in zweisprachig-binationalen Paaren/Familien in der Schweiz untersucht, und die erste, die sich dieser Frage in Bezug auf die Sprachkombination Russisch und Französisch annimmt.

The Perceived AIDS Preventative Utility of Knowing One's Partner Well

The public health advice to "either know your partner well, or use condoms" may have led to higher levels of risky sexual behaviour between well-acquainted individuals whose HIV status is unknown. This study assessed the extent to which college students believe that knowing their partner well eliminates the need to practice safer sex, and measured the relationship between such beliefs and the performance of necessary safer sexual practices, such as using condoms during sexual intercourse. Endorsement of beliefs that partner knowledge made safer sex unnecessary was common, and agreement with these beliefs correlated significantly and negatively with levels of AIDS preventive behaviours and behavioural intentions, especially among women. In conclusion, the public health dictum to "know your partner" has been widely internalized, and may be contributing to risky sexual behaviour. Consideration should be given to rejecting explicitly the "know your partner" advice, and to re-educating the public regarding the necessity of consistently practising safer sex with any individual whose HIV status is unknown.

The effect of African Americans' ethnographic paradigms and cultural explanatory model of breast cancer in framing the male partner's attitudes and behaviors about the woman's breast cancer diagnosis

The disparate burden of breast cancer-related morbidity and mortality experienced by African American women compared with women of other races is a topic of intense debate in the medical and public health arenas. The anomaly is consistently attributed to the fact that at diagnosis, a large proportion of African American women have advanced-stage disease. Extensive research has documented the impacts of cultural factors and of socioeconomic factors in shaping African American women's breast-health practices; however, there is another factor of a more subtle influence that might have some role in establishing these women's vulnerability to this disease: the lack of or perceived lack of partner support. Themes expressed in the research literature reflect that many African American breast cancer patients and survivors consider their male partners as being apathetic and nonsupportive. ^ The purpose of this study was to learn how African American couples' ethnographic paradigms and cultural explanatory model of breast cancer frame the male partners' responses to the women's diagnosis and to assess his ability to cope and willingness to adapt to the subsequent challenges. The goal of the study was to determine whether these men's coping and adaptation skills positively or negatively affect the women's self-care attitudes and behaviors. ^ This study involved 4 African American couples in which the woman was a breast cancer survivor. Participants were recruited through a community-based cancer support group and a church-based cancer support group. Recruitment sessions were held at regular meetings of these organizations. Accrual took 2 months. In separate sessions, each male partner and each survivor completed a demographic survey and a questionnaire and were interviewed. Additionally, the couples were asked to participate in a communications activity (Adinkra). This activity was not done to fulfill any part of the study purpose and was not included in the data analysis; rather, it was done to assess its potential use as an intervention to promote dialogue between African American partners about the experience of breast cancer. ^ The questionnaire was analyzed on the basis of a coding schema and the interview responses were analyzed on the principles of hermeneutic phenomenology. In both cases, the instruments were used to determine whether the partner's coping skills reflected a compassionate attitude (positive response) versus an apathetic attitude (negative response) and whether his adaptation skills reflected supportive behaviors (the positive response) versus nonsupportive behaviors (the negative response). Overall, the women's responses showed that they perceived of their partners as being compassionate, yet nonsupportive, and the partner's perceived of themselves likewise. Only half of the women said that their partners' coping and adaptation abilities enabled them to relinquish traditional concepts of control and focus on their own well-being. ^ The themes that emerged indicate that African American men's attitudes and behaviors regarding his female partner's diagnosis of breast cancer and his ability to cope and willingness to adapt are influenced by their ritualistic mantras, folk beliefs, religious teachings/spiritual values, existential ideologies, socioeconomic status, and environmental factors and by their established perceptions of what causes breast cancer, what the treatments and outcomes are, and how the disease affects the entire family, particularly him. These findings imply that a culturally specific intervention might be useful in educating African American men about breast cancer and their roles in supporting their female partners, physically and psychologically, during diagnosis, treatment, and recovery. ^

Qualitative study: Understanding Mexican American women's experience in intimate partner violence

The purpose of this qualitative study was to gain an understanding of the experiences of Mexican American women living with intimate partner abuse relevant to the process of disclosure of abuse. Limited research exists on the experiences of women who are of Mexican descent living with intimate partner abuse and their disclosure of abuse. Factors that influence disclosure for other populations are well articulated in the literature however, these factors have not been adequately verified in persons of Mexican descent. Data are reported from in-depth interviews with 26 clients at a shelter and an outreach agency in a south Texas-Mexico border community. Semi-structured interview guide was used to elicit information over an 11 month period. A grounded theory ethnography approach was used to analyze data. Verification strategies and constant comparison techniques (e.g. investigator responsiveness, methodological coherence, sampling adequacy, an active analytic stance, and saturation) enhanced rigor of analysis. Nineteen Mexican immigrant women and seven Mexican American women participated in the study. Several themes were discerned related to women's experiences in abuse: painful living, questioning endurance, and confronting reality. In almost every participant's account there was a description of repeated victimization by her intimate partner or partners, and again, by others within and outside her network. The participants discussed several cultural factors (e.g. embarrassment, concerns for family, avoidance of causing pain to family, protection of partner, avoidance of being judged) that hindered their decisions whether or not to disclose. Participants noted that healthcare workers rarely asked probing questions regarding abuse. The timing and process of disclosure took many turns for women in this study. Some of the factors hindering women from disclosing were found to be influenced by cultural practices. The consequences of disclosure for many of the women led them to re-victimization. Implications for practice to avoid missed opportunities with women living in abuse are to: ask questions routinely to encourage disclosure of abuse and offer community resource information for women living in abuse or both.^

A global perspective on intimate partner violence during pregnancy: An analysis of twelve developing countries

Violence against women has been recognized as a significant worldwide human rights issue and public health problem. Women of reproductive age may be particularly at risk, and pregnancy may trigger or escalate violence. Using data available from Demographic and Health Surveys on 271,103 women of reproductive age (15-49) from Bolivia, Cameroon, Colombia, Dominican Republic, Egypt, Haiti, India, Kenya, Nicaragua, Peru, South Africa, and Zambia, this study examined the nature of domestic violence during pregnancy in developing countries, including prevalence, demographic and risk factors, maternal and child health outcomes, perpetrators of violence, help-seeking behavior, and social support. In the majority of countries analyzed, violence during pregnancy consistently occurred at approximately one-third the rate at which domestic violence occurred overall. Younger women and women with more children were particularly at risk. Abuse during pregnancy was significantly associated with history of a terminated pregnancy and under-5 child mortality in most countries, and with neonatal and post-neonatal mortality in most Latin American countries. Women who were abused during pregnancy were most often abused by their current or former husband or boyfriend and most never attempted to seek help. In most countries that examined social support, women abused during pregnancy had significantly less contact with family and friends. Implications for practice and research are discussed. ^

Pregnancy intention, intimate partner violence, and the use of prenatal care in Jordan

Previous research has suggested an association between intimate partner violence and pregnancy intention status, and pregnancy intention status and the use of prenatal care services, however much of these studies have been conducted in high income countries (HIC) rather than low and middle income countries (LMIC). The objectives of this study were to examine the relationship between pregnancy intention status and intimate partner violence, and pregnancy intention status and the use of prenatal care among ever-married women in Jordan.^ Data were collected from a nationally representative sample of women interviewed in the 2007 Jordan Demographic and Health Survey. The sample was restricted to ever-married women, 15–49 years of age, who had a live birth within the five years preceding the survey. Multivariate logistic regression analyses was used to determine the relationship between intimate partner violence and pregnancy intention status, and pregnancy intention status and the use of prenatal care services.^ Women who reported a mistimed pregnancy (PORadj 1.96, 95% CI: 1.31–2.95), as well as an unwanted pregnancy (PORadj 1.32, 95% CI: 0.80–2.18) had a higher odds of experiencing lifetime physical and/or sexual abuse compared with women reporting a wanted pregnancy. Women not initiating prenatal care by the end of the first trimester had statistically significant higher odds of reporting both a mistimed (PORadj 2.07, 95% CI: 1.55–2.77) and unwanted pregnancy (PORadj 2.36, 95% CI: 1.68–3.31), compared with women initiating care in the first trimester. Additionally, women not receiving the adequate number of prenatal care visits for their last pregnancy had a higher odds of reporting an unwanted pregnancy (PORadj 2.11, 95% CI: 1.35–3.29) and mistimed pregnancy (POR adj 1.41, 95% CI: 0.96–2.07).^ Reducing intimate partner violence may decrease the prevalence of mistimed or unwanted pregnancies, and reducing both unwanted and mistimed pregnancies may decrease the prevalence of women not receiving timely and adequate prenatal care among women in this population. Further research, particularly in LMIC, is needed regarding the determinants of unintended pregnancy and its association with intimate partner violence as well as with the use of prenatal care services. ^

Exploring the Benefits of a Parent Partner Mentoring Program in Child Welfare

Parent partner mentoring programs are an innovative strategy for child welfare agencies to engage families in case planning and service delivery. These programs recruit and train parents who have been involved in the system and have successfully resolved identified child abuse or neglect issues to work with families with current open cases in the child welfare system. Parent partner mentors can provide social and emotional support, advocacy, and practical advice for navigating this challenging system. Insofar as parent partners share similar experiences, and cultural and socioeconomic characteristics of families, they may be more successful in engaging families and building trusting supportive relationships. The current study presents qualitative data from interviews and case studies of families who were matched with a parent partner in a large county in a Midwestern state. Interviews with families, parent partner mentors, child welfare agency staff, and community partners and providers suggest that parent partner programs may be just as beneficial for parent partner mentors as they are for families being mentored. These programs can build professional skills, help improve self-esteem, provide an avenue for social support, and may potentially prevent recidivism. Parent Partner programs also provide a mechanism for amplifying family voice at all levels of the agency.

Pontin52, an interaction partner of β-catenin, binds to the TATA box binding protein

β-catenin, the vertebrate homolog of the Drosophila Armadillo protein, has been shown to have dual cellular functions, as a component of both the cadherin-catenin cell adhesion complex and the Wnt signaling pathway. At Wnt signaling, β-catenin becomes stabilized in the cytoplasm and subsequently available for interaction with transcription factors of the lymphocyte enhancer factor-1/T-cell factor family, resulting in a nuclear localization of β-catenin. Although β-catenin does not bind DNA directly, its carboxyl- and amino-terminal regions exhibit a transactivating activity still not well understood molecularly. Here we report the identification of an interaction partner of β-catenin, a nuclear protein designated Pontin52. Pontin52 binds β-catenin in the region of Armadillo repeats 2–5 and, more importantly, also binds the TATA box binding protein. We provide evidence for an in vivo multiprotein complex composed of Pontin52, β-catenin, and lymphocyte enhancer factor-1/T-cell factor. Our results suggest involvement of Pontin52 in the nuclear function of β-catenin.

Structure of a cytochrome P450–redox partner electron-transfer complex

The crystal structure of the complex between the heme- and FMN-binding domains of bacterial cytochrome P450BM-3, a prototype for the complex between eukaryotic microsomal P450s and P450 reductase, has been determined at 2.03 Å resolution. The flavodoxin-like flavin domain is positioned at the proximal face of the heme domain with the FMN 4.0 and 18.4 Å from the peptide that precedes the heme-binding loop and the heme iron, respectively. The heme-binding peptide represents the most efficient and coupled through-bond electron pathway to the heme iron. Substantial differences between the FMN-binding domains of P450BM-3 and microsomal P450 reductase, observed around the flavin-binding sites, are responsible for different redox properties of the FMN, which, in turn, control electron flow to the P450.

MSF (MLL septin-like fusion), a fusion partner gene of MLL, in a therapy-related acute myeloid leukemia with a t(11;17)(q23;q25)

MLL (ALL1, Htrx, HRX), which is located on chromosome band 11q23, frequently is rearranged in patients with therapy-related acute myeloid leukemia who previously were treated with DNA topoisomerase II inhibitors. In this study, we have identified a fusion partner of MLL in a 10-year-old female who developed therapy-related acute myeloid leukemia 17 months after treatment for Hodgkin’s disease. Leukemia cells of this patient had a t(11;17)(q23;q25), which involved MLL as demonstrated by Southern blot analysis. The partner gene was cloned from cDNA of the leukemia cells by use of a combination of adapter reverse transcriptase–PCR, rapid amplification of 5′ cDNA ends, and blast database analysis to identify expressed sequence tags. The full-length cDNA of 2.8 kb was found to be an additional member of the septin family, therefore it was named MSF (MLL septin-like fusion). Members of the septin family conserve the GTP binding domain, localize in the cytoplasm, and interact with cytoskeletal filaments. A major 4-kb transcript of MSF was expressed ubiquitously; a 1.7-kb transcript was found in most tissues. An additional 3-kb transcript was found only in hematopoietic tissues. By amplification with MLL exon 5 forward primer and reverse primers in MSF, the appropriately sized products were obtained. MSF is highly homologous to hCDCrel-1, which is a partner gene of MLL in leukemias with a t(11;22)(q23;q11.2). Further analysis of MSF may help to delineate the function of MLL partner genes in leukemia, particularly in therapy-related leukemia.

ETO, fusion partner in t(8;21) acute myeloid leukemia, represses transcription by interaction with the human N-CoR/mSin3/HDAC1 complex

The t(8;21) translocation between two genes known as AML1 and ETO is seen in approximately 12–15% of all acute myeloid leukemia (AML) and is the second-most-frequently observed nonrandom genetic alteration associated with AML. AML1 up-regulates a number of target genes critical to normal hematopoiesis, whereas the AML1/ETO fusion interferes with this trans-activation. We discovered that the fusion partner ETO binds to the human homolog of the murine nuclear receptor corepressor (N-CoR). The interaction is mediated by two unusual zinc finger motifs present at the carboxyl terminus of ETO. Human N-CoR (HuN-CoR), which we cloned and sequenced in its entirety, encodes a 2,440-amino acid polypeptide and has a central domain that binds ETO. N-CoR, mammalian Sin3 (mSin3A and B), and histone deacetylase 1 (HDAC1) form a complex that alters chromatin structure and mediates transcriptional repression by nuclear receptors and by a number of oncoregulatory proteins. We found that ETO, through its interaction with the N-CoR/mSin3/HDAC1 complex, is also a potent repressor of transcription. This observation provides a mechanism for how the AML1/ETO fusion may inhibit expression of AML1-responsive target genes and disturb normal hematopoiesis.

The LIM-domain binding protein Ldb1 and its partner LMO2 act as negative regulators of erythroid differentiation

The nuclear LIM domain protein LMO2, a T cell oncoprotein, is essential for embryonic erythropoiesis. LIM-only proteins are presumed to act primarily through protein-protein interactions. We, and others, have identified a widely expressed protein, Ldb1, whose C-terminal 76-residues are sufficient to mediate interaction with LMO2. In murine erythroleukemia cells, the endogenous Lbd1 and LMO2 proteins exist in a stable complex, whose binding affinity appears greater than that between LMO2 and the bHLH transcription factor SCL. However, Ldb1, LMO2, and SCL/E12 can assemble as a multiprotein complex on a consensus SCL binding site. Like LMO2, the Ldb1 gene is expressed in fetal liver and erythroid cell lines. Forced expression of Ldb1 in G1ER proerythroblast cells inhibited cellular maturation, a finding compatible with the decrease in Ldb1 gene expression that normally occurs during erythroid differentiation. Overexpression of the LMO2 gene also inhibited erythroid differentiation. Our studies demonstrate a function for Ldb1 in hemopoietic cells and suggest that one role of the Ldb1/LMO2 complex is to maintain erythroid precursors in an immature state.
