Growing ties to private industry have prompted many to question the impartiality of academic bioethicists who receive financial support from for-profit corporations in exchange for ethics-related services and research. To the extent that corporate sponsors may view bioethics as little more than a way to strengthen public relations or avoid potential controversy, close ties to industry may pose serious threats to professional independence. New sources of support from private industry may also divert bioethicists from pursuing topics of greater social importance, such as the needs of medically underserved communities. To inform ongoing debates about the financing of bioethics and its transparency to those concerned about potential sources of bias, we examined funding disclosures appearing in original research reports in major bioethics journals. Reviewing research published over a 15-year period, we found little evidence that for-profit corporations are influencing bioethics research directly. Instead, we found evidence that a great number of organizations, both public and private, support bioethics research. These findings suggest that worries about the cooption of bioethics research by a few interested stakeholders are greatly overstated and undersupported by available data. 相似文献

A widely used measure of societal influences on body image and eating disturbances—the Sociocultural Attitudes Toward Appearance Questionnaire (SATAQ) was validated in women with eating disorders. The original SATAQ and measures of convergence and divergence were administered to 165 eating disordered inpatients. Factor analyses were conducted to determine the underlying structure of the SATAQ. Convergent validity, diagnostic category norms and the predictive utility of the revised SATAQ were examined. Factor analyses indicated three factors: Internalization, Awareness, and Success. Internalization significantly predicted treatment success after controlling for admission BMI and drive for thinness. The revised SATAQ-ED measures multiple aspects of societal influence, predicts short-term outcome, and can be a useful tool for evaluating potential outcome and treatment efficacy. 相似文献

Intergroup emotions theory (IET) posits that when social categorization is salient, individuals feel the same emotions as others who share their group membership. Extensive research supporting this proposition has relied heavily on self-reports of group-based emotions. In three experiments, the authors provide converging evidence that group-based anger has subtle and less explicitly controlled consequences for information processing, using measures that do not rely on self-reported emotional experience. Specifically, the authors show that intergroup anger involves arousal (Experiment 1), reduces systematic processing of persuasive messages (Experiment 2), is moderated by group identification (Experiment 2, posttest), and compared to intergroup fear, increases risk taking (Experiment 3). These findings provide converging evidence that consistent with IET, emotions triggered by social categorization have psychologically consequential effects and are not evident solely in self-reports. 相似文献

This study investigated changes in day-to-day affect, behavior, and physiology (hypothalamic-pituitary-adrenocortical axis activity) associated with temporary physical separations from romantic partners (such as those brought about by work-related travel). Daily diaries and measures of salivary cortisol were collected from 42 couples over a 21-day period that was timed to coincide with a naturally occurring 4- to 7-day separation. There were significant changes from preseparation to separation and from separation to reunion in the quality of partners' interactions, their positive and negative affect, sleeping problems, subjective stress, physical symptoms, and cortisol levels. Separation and reunion effects were generally more pronounced in homebound partners, partners with high attachment anxiety, and partners who had less contact with each other during the separation. Separation and reunion effects were not moderated by relationship length, relationship satisfaction, how often couples underwent separations, or the presence of children in the home. The results are discussed with respect to the role of daily proximity and contact between partners for day-to-day affective and physiological regulation. 相似文献

To assess psychopathology in transsexuals at different phases of sex reassignment, we administered the Spanish adaptation of the MMPI-2 (Avila-Espada & Jiménez-Gómez, 1999) to 107 male-to-female and 56 female-to-male transsexuals. Except for the Mf scale, mean T scores from the Clinical scales were within the normal range and did not differ between sexes. Male-to-female transsexuals seeking sex-reassignment hormonal therapy, but not female-to-male patients, scored significantly higher on the Depression, Hysteria, Psychopathic Deviate, Schizophrenia, and Social Introversion scales than patients seeking sex-reassignment surgery. The results show that the majority of patients were free of psychopathology. Transsexuals in the initial phases of sex reassignment may experience more distress than in later phases; however, these results are unlikely to reflect clinically relevant differences. 相似文献

The interpersonal process model of intimacy (H. T. Reis & P. Shaver, 1988) proposes that self-disclosure and empathic responding form the basis of intimate interactions. This study examined this model in 102 community couples who completed intimacy measures following videotaped discussions about relationship injuries occurring both within and outside the relationship. Observational assessments of self-disclosure and empathic responding, as well as their respective components, were related to self-reported ratings of post-interaction intimacy. Men's own disclosure and empathic responding predicted their feelings of intimacy, whereas women's intimacy was predicted by their partner's disclosure and empathic responding. Self-disclosure and empathic responding appear to be important behavioral determinants of intimate feelings, but the manner in which they influence intimacy differs according to gender. 相似文献

A Prevalence Study on Internalizing Problems Among Primary School Children in Hong Kong 总被引:1,自引:0,他引:1
Angela F. Y. Siu 《Journal of child and family studies》2008,17(6):779-790
Studies in Hong Kong indicated that there is a tendency for young children to use internalizing as a means to cope with their
daily difficulties. Mother–child relationship has been seen as a factor affecting a child’s adaptive coping skills. In this
study, we explored the prevalence of internalizing problems among primary school children in Hong Kong, as well as the mother–child
relationship that contribute to children’s internalizing problems. Data used to assess the internalizing behavior among 1598
primary school children were collected from their mothers. The estimated prevalence of internalizing problem was 11.4%. This
prevalence was based on the cutoff point for internalizing disorders according to the Child Behavior Checklist (CBCL). The
CBCL internalizing score was significantly correlated with mother–child relationship as measured using the Parent–Child Relationship
Questionnaire (PCRQ). Results from the PCRQ indicated that children’s internalizing problems were positively correlated with
mother’s use of verbal punishment and rejection as well as their possessiveness and protection on their children. On the other
hand, a nurturing and intimate relationship between mother and child was an important factor contributing to the development
of mentally healthy children. Implications of this study and suggestions for further research were discussed. 相似文献

Extinction, a form of learning that has the ability to reshape learned behavior based on new experiences, has been heavily studied utilizing fear learning paradigms. Mechanisms underlying extinction of positive-valence associations, such as drug self-administration and place preference, are poorly understood yet may have important relevance to addiction treatment. Data suggest a major role for the noradrenergic system in extinction of fear-based learning. Employing both pharmacological and genetic approaches, we investigated the role of the alpha(2)-adrenergic receptor (alpha(2)-AR) in extinction of cocaine-conditioned place preference (CPP) and glutamatergic transmission in the bed nucleus of the stria terminalis (BNST). We found that pre-extinction systemic treatment with the alpha(2)-AR antagonist yohimbine impaired cocaine CPP extinction in C57BL/6J mice, an effect that was not mimicked by the more selective alpha(2)-AR antagonist, atipamezole. Moreover, alpha(2A)-AR knockout mice exhibited similar cocaine CPP extinction and exacerbated extinction impairing effects of yohimbine. Using acute brain slices and electrophysiological approaches, we found that yohimbine produces a slowly evolving depression of glutamatergic transmission in the BNST that was not mimicked by atipamezole. Further, this action was extant in slices from alpha(2A)-AR knockout mice. Our data strongly suggest that extinction-modifying effects of yohimbine are unlikely to be due to actions at alpha(2A)-ARs. 相似文献
