Nine female participants shared their experiences of body satisfaction, spiritual beliefs, and the intersection of these domains. Using phenomenological inquiry, the authors identified 6 themes in participant interviews. The authors discuss ways in which this study extends previous research, in addition to providing suggestions for counseling practice.  相似文献

It is broadly held that confidentiality may be breached when doing so can avert grave harm to a third party. This essay challenges the conventional wisdom. Neither legal duties, personal morality nor personal values are sufficient to ground professional obligations. A methodology is developed drawing on core professional values, the nature of professions, and the justification for distinct professional obligations. Though doctors have a professional obligation to prevent public peril, they do not honor it by breaching confidentiality. It is shown how the protective purpose to be furthered by reporting is defeated by the practice of reporting. Hence there is no conflict between confidentiality and the professional responsibility to protect endangered third parties.  相似文献

The major aim of the present study was to investigate the effect of age on positive body image (operationalized as body appreciation) across the female lifespan. A secondary aim was to examine the effect of age on the relationship between positive body image and body satisfaction. Participants were 158 women aged between 18 and 75 years who completed questionnaire measures of body appreciation and body dissatisfaction–satisfaction. A significant positive linear relationship was found between age and body appreciation; that is, older women had higher levels of body appreciation than their younger counterparts. Although body appreciation was positively correlated with body dissatisfaction–satisfaction across all age groups, the association was weaker for older women. The results contribute to a richer picture of women's body image across the lifespan, as well as confirming positive body image as something beyond the mere absence of body dissatisfaction.  相似文献

The present study tested the hypothesis that men's drive for muscularity would be associated with their valuation of domination, power, status, and aggression over others. A community sample of 359 men from London, UK, completed measures of drive for muscularity, social dominance orientation, right-wing authoritarianism, trait aggression, and need for power, as well as their demographic details. Bivariate correlations showed that greater drive for muscularity was significantly correlated with most of the measures and their subscales. However, in a multiple regression analysis, the only significant predictor of drive for muscularity was support for group-based dominance hierarchies (Adj. R2 = .17). These results suggest that men's drive for muscularity is associated with a socio-political ideology that favours social dominance.  相似文献

Viewing thin models, pervasive in popular culture, is correlated with body dissatisfaction and anxiety in women. Whether or not the same is true when viewing healthy weight models is unknown. In this study we tested whether viewing healthy weight models increases the ideal female body size. Body image, anxiety, happiness and depression were measured in 44 female participants following viewing of images of thin or healthy weight models (within-subject separated by two weeks). We found that after viewing images of healthy weight models, women's body ideals (as measured by a participant-adjusted virtual model) were significantly larger than when the same women viewed images of very thin models. This effect was greatest in those women with the highest levels of baseline anxiety (as measured by the Hospital Anxiety and Depression Scale). These results suggest that viewing healthy weight models results in more healthy body ideals than those typically promoted through media.  相似文献

This paper provides a new philosophical argument against the lifting of the ban on doping in sports. It makes several assumptions for the sake of argument, one of which is, ironically, the moral justification of the lifting of the ban on sports doping. It is, then, a reductio ad absurdum against the claim that said ban should be lifted. Following this is a preliminary discussion concerning how doping athletes ought to be punished given that there ought to be a ban on doping due to the implausibility of the position to lift said ban. Considerations from responsibility and punishment theories are brought to bear in order to discern which punishments are most fitting for those athletes caught doping in designated clean sports competitions.  相似文献

Abstract

Medical family therapists (MedFTs) and pharmacists in the context of interdisciplinary collaboration will be discussed. In an effort to build and reflect on their own professional experiences, recognizing the need to address wellbeing from a multitude of perspectives, and with the goals of improving access to care by identifying potential partnership opportunities between the two professions, the authors synthesized findings from pertinent articles using Medline and PsycInfo. This paper will illuminate the precise roles of MedFTs and pharmacists, how they fit into the interdisciplinary healthcare team, and anticipated facilitators and barriers in this undertaking to enhance patient care.  相似文献

The metastable particles in an Al–Zn–Mg–Cu alloy have been examined at atomic-resolution using high-angle annular dark field (HAADF) imaging. In under-aged conditions, thin η′ plates were formed with a thickness of seven atomic planes parallel to the {111}Al planes. The five inner planes of the η′ phase appear to be alternatively enriched in Mg and Zn, with two outer planes forming distinct Zn-rich interfacial planes. Similar Zn-rich interfacial enrichment has also been identified for the η phase, which is a minimum 11-plane thick structure. In rare instances, particles less than seven planes were found indicating a very early preference for seven-layer particle formation. Throughout the aging, the plate thickness appears constant, while the plate radius increases and no particles between 7 and 11 planes were observed. Based on the HAADF contrast, our observations do not support the η′ models previously set forth by other authors. Clear structural similarities between η′ and η were observed, suggesting that drawing distinctions between η′ and η phases may not be necessary or useful.  相似文献

为探讨术前进行人文关怀式沟通和健康教育对肺癌手术患者全麻诱导后心理和生理的影响,将83例非同期别的肺癌手术患者(均采用全身麻醉,双腔管气管插管辅助通气)分成两组。观察组进行人文关怀式沟通,对照组采用普通沟通。判定方法采用焦虑自评量表(SAS),根据焦虑评分反映两组患者入院即刻及手术前的心理变化情况,监测全麻诱导即刻与全麻诱导气管插管后5min患者平均动脉压(MBP)的波动、心率(HR)的变化,用两个时间段两个变量的差值来反映两组患者全麻诱导期发生心理和生理反应的情况。结果显示,两组患者入院即刻焦虑差异无统计学意义(P〉0.05);手术前SAS评分两组患者较入院即刻降低(P〈0.05),并且观察组与对照组相比下降更明显(P〈0.01);观察组患者MBP波动无统计学意义(P〉0.05)、HR波动有统计学意义(P〈0.05)。因此,证实人文关怀式沟通和健康教育能够减轻肺癌患者在心理和生理两个方面对麻醉和手术产生的不良反应。  相似文献

临床思维与决策能力培养是医学生不可或缺的一门必修课程,临床医生实际上每天处于临床决策之中,必须为疾病提供诊断和治疗的决策.而当前临床医学生在此方面训练甚少,临床工作具有很大的不可预知性和不可确定性,尤其是在手术室繁忙、变化的环境中,进行高效的临床决策就显得尤其重要.本文阐述了临床思维与临床决策在医学教育中的重要地位及其相互关系,分析当前医学生临床实践中的思维与决策方面存在的问题.并从临床实际角度出发,探讨如何提高医学生临床思维与决策能力的方法,对促进医学教育模式改革,提高医学教育质量具有重要推动作用.  相似文献
