In this response to Johnson, Oh reaffirms the scholarly vision of Kelsay and Twiss, elaborates upon Muslim perspectives on human rights, and questions the emphasis on violent humanitarian interventions as part of the Responsibility to Protect mandate. Oh suggests that, in light of the historical relationship between Muslim and non‐Muslim states and the aftermath of the second Iraq War, more consideration be given to the rebuilding of Muslim‐majority societies. Oh also highlights the concept of duty as a religiously based ideal to which governments of Muslim nations ought to be held.  相似文献

African American couples (n = 331) with children, 89% of whom were married, were assigned to either (a) a culturally sensitive couple‐ and parenting‐enhancement program (ProSAAF) or (b) an information‐only control condition in which couples received self‐help materials. Husbands averaged 41 years of age and wives averaged 39 years. We found significant effects of program participation in the short term on couple communication, which was targeted by the intervention, as well as over the long term, on self‐reported arguing in front of children. Long‐term parenting outcomes were fully mediated by changes in communication for wives, but not for husbands. For husbands, positive change depended on amount of wife reported change. We conclude that wives' changes in communication from baseline to posttest may be more pivotal for the couples' long‐term experience of decreased arguing in front of children than are husbands' changes, with wives' changes leading to changes in both partners' reports of arguments in front of children.  相似文献

The need for parenting and relationship strengthening programs is important among low‐income minority parents where the burden of relational and parental stressors contributes to relationship dissolution. We examine these stressors among young parents. Data were collected from four focus groups (N = 35) with young parents. Data were audio‐recorded and transcribed. Inductive coding was used to generate themes and codes, and analysis was completed using NVivo. Relationship and parenting challenges, values, and areas of need were the three major themes that emerged. Women's relationship challenges were family interference and unbalanced parenting, and men reported feeling disrespected and having limited finances. Common relationship challenges for women and men were family interference and unbalanced parenting. Both genders valued trust, communication, and honesty in relationships. Areas of need for women and men included: improving communication and understanding the impact of negative relationships on current relationships. Parenting challenges for women were unbalanced parenting, child safety, and feeling unprepared to parent; men reported limited finances. Both genders valued quality time with child to instill family morals. Areas of need for women and men included learning child discipline techniques and increasing knowledge about child development. Finally, women and men have relationship and parenting similarities and differences. Young parents are interested in learning how to improve relationships and co‐parent to reduce relationship distress, which could reduce risk behaviors and improve child outcomes.  相似文献

By means of a clinical illustration, the author describes how the intersubjective exchanges involved in an analytic process facilitate the representation of affects and memories which have been buried in the unconscious or indeed have never been available to consciousness. As a result of projective identificatory processes in the analytic relationship, in this example the analyst falls into a situation of helplessness which connects with his own traumatic experiences. Then he gets into a formal regression of the ego and responds with a so‐to‐speak hallucinatory reaction—an internal image which enables him to keep the analytic process on track and, later on, to construct an early traumatic experience of the analysand.  相似文献

This study examines the relationship between the psychoanalytic concept of object relations and real life behavior of being in an intimate relationship among heterosexual women. In a multi‐method approach we used two different measures; the self‐report Bell Object Relations and Reality Testing Inventory (BORRTI; Bell, Billington & Becker, 1986 ) and the performance based Thematic Apperception Test (TAT) Social Cognition & Object Relations Scale‐ Global Rating Method SCORS‐G (Westen, 1995 ) to measure the object relations of 60 women. The Alienation subscale of the BORRTI and understanding of social causality subscale of the SCORS‐G explained 34.8% of variance of the intimate relationship variable. Thus, women involved in a romantic relationship reported lower rates of alienation on the BORRTI and produced TAT narratives that were more adaptive with regard to understanding of social causality as measured by the SCORS‐G than those not currently in a relationship. Results are discussed with reference to the relationship between object relations and real life measures of healthy individuals and in light of the need for a multi‐method approach of assessment.  相似文献

Previous research has evaluated the motor proficiency of children with neurofibromatosis type 1 (NF1) and found delays on the balance subtest. However the balance subtest was found to have low sensitivity for identifying balance impairments. This study examines the differences in postural control between children with NF1 and peers with typical development using a force plate. A single limb stance test on a force plate was completed for all participants. The force plate variables, center of pressure maximum distance in the anterior/posterior direction (COPmax A/P) and center of pressure velocity (COPvel A/P) were compared between groups. The NF1 group’s performance was significantly poorer than the control group in both COPmax A/P (p = .01) and COPvel A/P (p = .01). When separated into specific age ranges, only the children in the NF1 group between 5 and 12 years of age demonstrated statistically significant differences in the COP variables. The COP variables for the 13- to 18-year-old group were not significantly different. These results indicate that young children with NF1 have poor postural control. However, postural control appears to improve with maturation.  相似文献

Frontal and parietal electroencephalographic (EEG) asymmetries mark vulnerability to depression and anxiety. Drawing on cognitive theories of vulnerability, we hypothesise that cortical asymmetries predict attention to threat. Participants completed a dot-probe task in which bilateral face displays were followed by lateralised targets at either short (300 ms) or long (1050 ms) SOA. We also measured N2pc to face onset as an index of early attentional capture. At long SOA only, frontal and parietal asymmetry interacted to predict attentional bias to angry faces. Those with leftward frontal asymmetry showed no attentional bias. Among those with rightward frontal asymmetry those with low right parietal activity showed vigilance for threat, and those with high right parietal activity showed avoidance. Asymmetry was not related to the N2pc or to attentional bias at the short SOA. Findings suggest that trait asymmetries reflect function in a fronto-parietal network that controls attention to threat.  相似文献

细胞周期过程中癌基因的激活与抑癌基因的失活等是造成细胞恶性增殖、转化的重要因素。细胞周期G1/S期各调节因子的异常改变与细胞癌变关系尤为密切。P16、CyclinDl和CDK4均为重要的细胞周期调控蛋白,任何原因导致这些蛋白异常表达时,将引起细胞周期调节失控,导致肿瘤的发生和恶性演进。结直肠癌的发生发展同上述三者关系密切。本实验通过免疫组化方法进行检测结直肠癌组织中P16、CyclinDl和CDK4三者的表达及其与结直肠癌临床指标的关系,为揭示三者在结直肠癌发生发展中的作用提供一定的实验依据。  相似文献

IntroductionBecause changing personal beliefs about treatment could help improve adherence, having a validated tool for identifying these beliefs is important.ObjectiveThis study sought to validate the French version of the Beliefs about Medicines Questionnaire (BMQ-f©).MethodData were gathered among 253 patients with type 2 diabetes and 123 HIV patients with the help of self-reported questionnaires, including the Beliefs about Medicines Questionnaire, a French adherence assessment, and some demographic variables.ResultsConfirmatory factor analyses show the French version of the BMQ has the same factorial structure as the English original in both diabetes and HIV samples. All items load on their expected factor namely specific-necessity, specific-concern, general-harm, and general-overuse. Moreover, each scale revealed good internal consistency and retained the psychometric qualities of the original version. These satisfactory properties were consolidated by predictive validity data that demonstrate the impact of treatment beliefs on adherence levels.ConclusionFindings are discussed in light of previous diabetes and HIV studies. The French BMQ proved to be a good way of quickly identifying inaccurate beliefs about treatment. It could be a useful tool in French clinical practice, such as in patient education.  相似文献
