日本安乐死立法之考察与研究

日本成文法律目前尚无关于安乐死的明确规定,但是一些典型的判例已经对安乐死合法的条件做出了界定。日本社会和民众绝大多数能够接受消极安乐死,但是强烈反对积极安乐死。积极安乐死属于日本刑法上的杀人罪行为,但是量刑较轻。     

Should We Call E.T.? An Ethical-Political Analysis of METI

Is it possible to mount a compelling ethical argument for METI? As we have argued elsewhere, conventional ethical theories are highly anthropocentric, making them difficult to apply to unknown alien intelligences, whose characteristics, needs, and concerns may differ radically from our own. In the absence of ethically relevant information about ETIs we contend that it isn’t possible to provide a strong conventional ethical argument for METI. Drawing upon the ancient, less widely known, ethical-political tradition of cosmopolitanism, however, we show how proponents of METI could provide an ethical argument for trying to contact ETIs under the right procedural conditions.     

啮齿动物主动母性行为动态改变的神经机制

主动母性行为是雌性哺乳动物在哺乳期内有效照料幼崽的一种动机行为, 对幼崽的生存和行为发展有重要影响。证据显示, 啮齿动物的主动母性行为会经历从产后早期的发动和维持到晚期衰退的动态改变, 反映了雌鼠对幼崽奖赏价值阶段性变化的适应; 这一过程不仅涉及分娩激素事件开启下丘脑内侧视前区(MPOA)-中脑腹侧被盖(VTA)-伏隔核(NA)-腹侧苍白球(VP)通路, 还需要杏仁核基底外侧核(BLA)和内侧前额皮层(MPFC)等脑区对上述通路进行实时调节。哺乳期主动母性行为动态改变及其神经机制的研究, 可以加深对行为进化和早期发展的认识, 也对人类母亲产后抑郁等临床问题的干预有借鉴意义。本文首先利用条件化位置偏好(CPP)任务的行为学证据分析幼崽奖赏价值与主动母性行为动态改变的关系; 然后系统阐述调控这一动态改变的神经机制; 最后对未来需要研究的一些重要问题或方向进行探讨。     

自闭症儿童能否痊愈?——来自谱系个体“最佳结果”及剩余缺陷研究的证据分析

自闭症谱系障碍预后效果不佳, 通常被认为是一种伴随终生的疾病。不过随着研究的拓展和深入, 部分早期被诊断为自闭症的儿童, 随着年龄增长和相关干预措施的介入, 其认知、适应性等方面均可达到正常发展水平, 并且不再符合自闭症的诊断标准, 即达到了“最佳结果”。但多数个体仍然存在不同程度的剩余缺陷。本文以自闭症预后结果评定和“最佳结果”定义演变为切入点, 分析“最佳结果”个体剩余缺陷的具体表现, 并梳理此类群体的个体特征与结果预测因素, 以期能为自闭症个体的系统干预提供有效依据。     

Differential Effect of Two Mental Stress Tasks on Arterial Stiffness

Acute mental stress is believed to induce transient arterial dysfunction, but relatively few data are available. We therefore examined the effect of mental stress tasks that could induce differential hemodynamic responses on arterial dysfunction. Forty‐eight participants conducted either a mental arithmetic (MA) task or a mirror‐tracing (MT) task. Cardiovascular indices and arterial stiffness were measured before, during, and after these tasks. Analysis revealed that increases in arterial stiffness during the task and during recovery were more pronounced for the MA than for the MT, and that evoked hemodynamic response was more myocardial for MA than for MT. These results clearly show that MA and MT tasks that induce differential hemodynamic responses have a differential effect on arterial stiffness. This finding sheds light on the underlying mechanism that may account for the relationship between cardiovascular reactivity and cardiovascular disease.     

An Examination of the Effects of Stress Management Training for Japanese College Students of Social Work

The purpose of the present study was to examine the effects of a stress-management program for college students of social work on their perception of mental stress and stress-coping strategies. Students in a stress-management group received progressive muscle training, cognitive-behavioral skills training, and assertion training for 14 weeks. Their life events, stress symptoms, and stress-coping skills (active and passive coping skills), evaluated on the first and last days of program, were compared with those of a control group. The effect of the participants' trait anxiety on those variables was also examined. Because the stress-management program in the present study focused on coping strategies, it was expected that the students' coping skills would change. The results showed that passive coping skills of students in the stress-management group had decreased after the program.     

Recovery Recovered

The most controversial condition that the AGM theory of rational belief change places on belief contraction is the recovery condition. The condition is controversial because of a series of putative counterexamples due (separately) to I. Levi and S. O. Hansson. In this paper we show that the conflicts that Levi and Hansson arrange between AGM contraction and our intuitions about how to give up beliefs are merely apparent. We argue that these conflicts disappear once we attend more closely to the identification of the beliefs contracted away in each counterexample case. Since, on our view, speakers" belief contraction intentions are often more complicated than they may first appear, we are led to develop apparatus for thinking about the communication and identification of those intentions. Our argument refocuses attention on the difficult question of how to apply the AGM theory to particular cases.     

Implementing Skills for Psychological Recovery at a Psychology Training Clinic During COVID-19

The COVID-19 global pandemic has disrupted the routine provision of community mental health services, which is especially concerning given that emerging data suggest a rise in mental health concerns related to the COVID-19 crisis (Xiong et al., 2020). Thus, it seems imperative to provide trauma-informed services that are tailored to clients’ coping with the pandemic and can be effectively delivered via telehealth. The goals of these important services would be to mitigate current distress, help prevent the onset of long-term mental health problems, and facilitate client safety during a public health crisis. The present article provides an overview of adoption and telehealth implementation of the Skills for Psychological Recovery (SPR) secondary prevention program within a psychology training clinic. Initial clinical outcome data supported the program’s success in reducing mental health symptoms among individuals in psychological distress due to the COVID-19 crisis; however, the results were more striking for adults than for youths. The article concludes with recommendations for broader implementation and future directions for clinicians, supervisors, organizations, and researchers.     

工作记忆表征精度加工需求对注意引导的影响

采用注意捕获范式, 通过行为和事件相关脑电位(ERP)实验, 探讨工作记忆表征精度加工需求对注意引导的影响, 行为结果发现, 在低精度加工需求条件下, 只有一个工作记忆表征引导注意, 且处于高激活状态的工作记忆表征产生的注意捕获大于低激活状态; 而在高精度加工需求条件下, 有两个工作记忆表征引导注意, 且处于高、低激活状态的工作记忆表征产生的注意捕获没有差异。ERP结果显示, 高精度加工需求条件下诱发的NSW和LPC大于低精度加工需求条件; 在高精度加工需求条件下, 干扰项与记忆项匹配比不匹配时, 诱发更大的N2和更小的N2pc, 而在低精度加工需求条件下, 干扰项与记忆项匹配和不匹配时诱发的N2、N2pc没有差异。研究表明, 工作记忆表征精度加工需求影响注意引导的机制可能是高精度加工需求下, 工作记忆表征消耗的认知资源增加, 搜索目标获得的资源减少, 干扰项捕获的注意增加。
