浅议侵害患者知情同意权的性质及赔偿

知情同意是患者自主权的重要体现,侵害患者知情同意权是引发医惠纠纷的常见原因。知情同意权是患者身体权、隐私权、财产权和支配权的集中体现,对患者知情同意权的侵害直接表现为对患者身体权、隐私权或财产权的侵害,医疗机构应该承担相应的精神损害赔偿、财产损害赔偿的责任。     

意义维持模型:理论发展与研究挑战

意义维持模型是近年来兴起的社会心理学理论。它主张将意义维持作为个体最基本的社会动机,认为个体在遭受意义违反后,会激起厌恶性情绪,而缓解厌恶情绪成为意义维持的动力,促使个体采取补偿行为修补意义系统。该理论对认知失调等理论进行了一定程度的整合,并且具有强大而广泛的解释力。研究者对其意义违反、厌恶激起和行为补偿三个基本过程的理论阐述日臻完善,同时其主要观点也得到较多实证研究的支持。在意义维持模型的研究中,也存在意义等概念边界模糊、厌恶激起的中介作用论证不充分、启动和补偿的竞争解释等问题。今后的研究一方面需要进一步检验意义维持的基本过程,另一方面也可以讨论行为补偿的运作、主动的意义维持等问题。     

非故意损害下的过度补偿效应

个体的补偿和报复行为是人际损害领域的研究重点。本研究通过将损害者和受害者置于同一情境,揭示了非故意损害中的过度补偿效应。实验包括虚拟和真实两种非故意损害情境,损害方式包括经济损失和肉体伤害。组间变量是损害者、受害者和中立者三种角色,因变量是被试在分配任务中留给搭档或自己的分数或金钱。结果表明,在阅读或经历了相同的非故意损害事件后,损害者补偿给受害者的分数和金钱会显著高于受害者留给自己的数量,即过度补偿效应。     

Pedestrian detection using a moving camera: A novel framework for foreground detection

While background subtraction techniques have been widely applied to detect moving objects in a video stream captured by a static camera, detecting moving objects using a moving camera still represents a challenging task. In this context, pedestrian detection using a camera placed on the top of a vehicle’s windshield has been rarely investigated. This is mainly due to the background ego-motion. Since the scene captured by the camera seems in motion, it is very difficult to distinguish the moving pedestrians from the others that belong to the static part of the scene. For this reason, a compensation step is needed to suppress the ego-motion. This paper presents a study on the main challenges facing pedestrian detection systems as well as methods proposed to handle these challenges. A novel trajectory classification framework for detecting pedestrians even in challenging real-world environments is proposed. The proposed method models the background motion between two consecutive frames in order to compensate the camera motion. Then, it defines a classification process that differentiates between the background and the foreground in the frame. Using the defined foreground, we consequently identify the presence of pedestrians in the scene. The proposed method was validated on a public benchmark dataset: CVC-14 containing both visible and far infrared video sequences in day and night times. Experimental results confirm the effectiveness of the proposed approach in capturing the dynamic aspect between frames and therefore detecting the presence of pedestrians in the scene.     

Bilateral Transfer in Tapping Skill in the Absence of Peripheral Information

Bilateral transfer in a fast tapping task was investigated under normal (+FB) and reduced (-FB) feedback conditions, in the -FB experiment 36 Ss were assigned to 3 groups: preferred (PH) to non-preferred (NPH) shift; NPH to PH; and alternating trials of PH and NPH. With + FB 2 further groups of 12 Ss transferred PH to NPH or NPH to PH. 8 preshift and 8 postshift trials were given. The alternating group had 8 PH and 8 NPH trials. In preshift performance increment was found in ail groups except in +FB with NPH. With +FB some facilitation in transfer was obtained for the NPH; under -FB marked positive transfer was found for the PH. Alternating PH and NPH performance conformed to preshift levels. Results were discussed in terms of differential central control processes for the two hands.     

The Assessment of Post‐traumatic Stress Disorder for Workers' Compensation in Emergency Service Personnel

There is considerable debate concerning the diagnosis of post‐traumatic stress disorder (PTSD) in compensation claims. This study reviewed the quality of the assessment reports prepared by clinicians who evaluated 31 emergency service workers making PTSD‐related compensation claims. Assessments were conducted by 4‐year trained psychologists (39%), psychologists holding a masters degree (36%), and psychiatrists (19%). The assessment reports were evaluated relative to the diagnostic criteria for PTSD in the Diagnostic and Statistical Manual of Mental Disorders 4th edition (2000). In the majority of cases (81%), the assessor determined that the emergency service worker had PTSD, but only one report met the minimum standard for that diagnosis. In the majority (65%) of cases the clinician failed to address the possibility of malingering. These data suggest that clinical assessment reports for PTSD frequently fail to meet minimum assessment standards.     

A Draft Model Aggregated Code of Ethics for Bioethicists

Bioethicists function in an environment in which their peers—healthcare executives, lawyers, nurses, physicians—assert the integrity of their fields through codes of professional ethics. Is it time for bioethics to assert its integrity by developing a code of ethics? Answering in the affirmative, this paper lays out a case by reviewing the historical nature and function of professional codes of ethics. Arguing that professional codes are aggregative enterprises growing in response to a field's historical experiences, it asserts that bioethics now needs to assert its integrity and independence and has already developed a body of formal statements that could be aggregated to create a comprehensive code of ethics for bioethics. A Draft Model Aggregated Code of Ethics for Bioethicists is offered in the hope that analysis and criticism of this draft code will promote further discussion of the nature and content of a code of ethics for bioethicists.     

如何唤起和缓解重大损失情绪—— 来自行为和脑成像的证据

本研究在没有真实伤害的情况下研究重大损失情绪及相应的脑机制。通过一系列行为和脑成像实验, 研究者们摸索出了可靠诱发重大损失情绪的范式, 并从对比效应和金钱补偿角度初步探讨了缓解这种情绪的方法。研究发现, 由于自我防御机制的存在, 抑制了被迫接受条件下重大损失情绪的唤起, 但却成功唤起了被迫选择条件下重大损失的情绪。此外, 研究还发现, 金钱补偿和对比效应都是缓解重大损失情绪的有效策略。本研究不仅有利于认识重大损失情绪的信息加工机制, 而且也为涉及重大损失情绪的心理咨询和保险理赔制度等提供了行为和脑成像证据。     

The Role of Stigma in Understanding Ethnicity Differences in Authoritarianism

Ethnic minorities often have shown higher mean levels of authoritarianism compared to Whites. However, no theoretical mechanism has been directly tested to explain these ethnicity differences. Using the stigma literature as a framework, two studies are presented that test a novel explanation for this difference, rooted in the devaluing that accompanies being a member of a stigmatized group in society. The results show that, in Study 1, ethnic minorities reported higher levels of authoritarianism in ways that could not be explained by traditional explanations of authoritarianism, including lower income, lower education, or lack of cognitive complexity. However, in Study 2, when participants were given the opportunity to affirm their sense of worth, ethnic minorities did not differ in their mean levels of authoritarianism compared to Whites. These findings are discussed in the context of understanding ethnic minority endorsement of authoritarianism in terms of self‐regulatory processes that may be related to their stigmatized condition in society.     

任务难度与老化对大脑激活的影响——以线索记忆编码为例

以汉语名词双字词对为材料,采用了两种性质、三种难度水平的线索回忆任务对12名老年被试和15名年轻被试的项目记忆编码过程进行fMRI扫描,考察在编码阶段大脑激活受任务难度变化和老化的影响。行为研究结果发现:年龄的主效应、难度的主效应以及难度与年龄交互作用均显著,即,随着任务难度的增加,老年人的成绩更加明显地低于年轻人。神经成像研究结果发现:(1)当词对的相关性降低时,大脑激活的增强主要表现为面积的增加,而当词对的频率降低时,主要表现在激活强度的增加上。(2)任务难度和大脑激活面积、强度之间均不存在对应的递增变化关系。(3)仅当词对的相关性降低时,老年人比年轻人调用了更多的额叶脑区。
