新型冠状病毒肺炎尚无治疗特效药和疫苗。在继续加强防控的同时,把有限的资源优先放在探索对重症和危重症患者的支持性治疗,积极建立和完善对重症、危重症患者及其家属的缓和医疗等方面,有利于患者群体利益最大化,经得起伦理辩护。缓和医疗有助于改善患者预后,降低住院病死率,有效缓解患者濒死痛苦;对医患双方而言,如果死亡已无可避免,帮助临终者走得平安、少些痛苦,是医学对患者最后的人文关怀。  相似文献

We performed a multilevel, multinational analysis using the 2012 European Social Survey dataset (N = 41 080, nested in 20 countries) to study how living in a non‐communist versus in a post‐communist country moderates the link between individual conservative values (drawn on Schwartz's theory of basic human values) and political orientation (assessed as self‐placement on the left–right axis and attitude towards economic redistribution). The results supported the moderating role of living in a non‐communist versus in a post‐communist country in the case both of political self‐placement and of attitude towards economic redistribution, even controlling for the countries' degree of individualism, power distance and democracy. Specifically, conservative values were positively related to a rightist political self‐placement among participants living in countries without a communist past, and to a favourable attitude towards economic redistribution in countries with a communist past. The limitations, implications and future directions of this study are discussed. Copyright © 2016 European Association of Personality Psychology  相似文献

There is a growing literature connecting poor motor coordination to physical and mental health outcomes in children and adolescents. These studies suggest that children with disorders such as developmental coordination disorder (DCD) are at greater risk for depression and anxiety, as well as obesity, and poor physical fitness. With regard to internalizing problems (symptoms of depression and anxiety), there is also evidence to suggest that the environment may play an important role in the etiology of psychological distress in this population. Cairney, Veldhuizen, & Szatmari, 2010 used the phrase “environmental stress hypothesis” to highlight the role that negative exposure to personal and interpersonal stressors might play in accounting for higher rates of internalizing symptoms in children with DCD. In this paper, we elaborate further on this basic premise, offering a model linking DCD to internalizing problems based on Pearlin’s stress process framework. In addition to stressors (risk) and protective factors, we incorporate both physical activity and obesity into our stress model. Next, we review the existing literature to see if there is evidence supporting specific components (pathways) of the model. In doing so, areas in need of further research are identified. Implications for intervention are also provided.  相似文献

There is an important anomaly to the causalist/compatibilist paradigm in the philosophy of action and free will. This anomaly, which to my knowledge has gone unnoticed so far, can be found in the philosophy of Harry Frankfurt. Two of his most important contributions to the field – his influential counterexample to the Principle of Alternate Possibilities and his ‘guidance’ view of action – are incompatible. Frankfurt's counterexample to the Principle works only if we do not understand action as Frankfurt does in his guidance account. If, on the other hand, we understand agency in terms of the agent's guidance, then his counterexample to the Principle fails because, then, counterfactual scenarios of Frankfurt-type counterexamples are such that what happens does not count as the relevant agent's action. So Frankfurt-type counterexamples do not show that the agent could not have avoided acting as she did: so they fail to offer a scenario in which the agent is intuitively responsible even though she could not have avoided acting as she did. Therefore, Frankfurt-type counterexamples do not challenge the Principle, according to which ‘a person is morally responsible for what he has done only if he could have done otherwise’. The importance of this inconsistency goes far beyond the issue of coherence within Frankfurt's philosophy. I shall argue that this inconsistency represents an important anomaly within the causalist/compatibilist framework; so that we should start to seriously consider having to move on from the established paradigm.  相似文献

对湖北省两所中学3219名初一至初三年级学生进行问卷调查,建立结构方程模型考察父母粗暴养育、核心自我评价、友谊质量和青少年智能手机成瘾的关系。结果发现:(1)核心自我评价在父母粗暴养育和青少年智能手机成瘾之间起部分中介作用,即父母粗暴养育既对青少年智能手机成瘾产生直接影响,也通过核心自我评价对青少年智能手机成瘾产生间接影响;(2)父母粗暴养育和核心自我评价的关系(中介作用的前半段路径)受到友谊质量的调节,即在高友谊质量和低友谊质量条件下,随着粗暴养育程度的增加,青少年核心自我评价均显著下降,但在高友谊质量的条件下,下降的程度更高。研究结果有助于揭示父母粗暴养育对青少年智能手机成瘾的影响及其作用机制,为预防和干预青少年智能手机成瘾带来一些重要的启示。  相似文献

Converging research suggests phenomenological and neurobiological similarities between excessive food consumption and addictive behaviour in substance dependence. Recently, the Yale Food Addiction Scale (YFAS) has been proposed for the assessment of addictive eating behaviour. The German version of the YFAS was administered to obese individuals seeking bariatric surgery (N?=?96). Factor structure, internal consistency, and item statistics were analysed. Forty participants (41.70%) received a food addiction diagnosis. The one-factorial structure of the YFAS, which has been found in non-clinical samples, could be confirmed. All but three items had factor loadings >.50. Internal consistency was α?=?.82. Item analysis revealed that items related to unsuccessful attempts to cut down and consumption despite physical and emotional problems were endorsed by the majority of participants. Findings support the use of the YFAS in clinical populations, while applicability of some items differs between clinical and non-clinical samples.

Depressive symptoms are common and can affect prognosis following acute coronary syndromes (ACS). This study examined the psychological factors, coping, anxiety, and perceived stress associated with depression following ACS. Psychological variables were assessed in 15 females and 66 males (M = 57 years, SD = 12). Repeated measures at 2, 12, and 24 weeks post-ACS compared depression, anxiety, perceived stress, and coping resources as determined by the Cardiac Depression Scale, Beck Depression Inventory-II, State Trait Anxiety Inventory, Perceived Stress Scale, and Coping Resources Inventory. Depression, anxiety, and perceived stress remained high in the depressed group across time. Coping scores at 2 weeks post-ACS predicted depression scores at 24 weeks post-ACS. It appears that trait anxiety and coping resources are related to depressive symptoms post-ACS.  相似文献

Past research has shown that counterfactual (“If…then…”) thoughts influence causal and responsibility attribution in the judicial context. However, little is known on whether and how the use of counterfactuals in communication affects lay jurors' and judges' evaluations. In two studies, we asked mock lay jurors (Study 1) and actual judges (Study 2) to read a medical malpractice case followed by an expert witness report, which included counterfactuals focused on either the physician, the patient, or external factors. Results showed that counterfactual focus had a strong effect on both lay jurors' and judges' causal and responsibility attributions. Counterfactual focus also moderated the effect of outcome foreseeability on responsibility attribution. Discussion focuses on how counterfactual communication can direct causal and responsibility attribution and reduce the importance of other factors known to influence judicial decision‐making. The potential implications of these findings in training programs and debiasing interventions are also discussed.  相似文献

以往研究发现个体能够同时巩固一定数量的项目信息进入视觉工作记忆系统。本研究将考察视觉工作记忆的巩固容量是否会受到分配到记忆项目上的注意资源量的影响。实验1在同时序列掩蔽范式的基础上, 用控制记忆项目呈现区域的大小的方法操纵被试的注意范围, 从而达到操纵分配到单个项目上的注意资源量的目的。研究结果显示, 被试的记忆成绩随着注意范围的扩大显著降低, 但在并行和序列呈现条件之间不存在显著差异; 实验2则证实实验1中对注意资源量分配的控制不会影响对项目的知觉编码效率。本研究结果表明, 分配在记忆项目上的注意资源量能够影响记忆巩固的效率, 但不会影响巩固容量。  相似文献
