Validating age-related functional imaging changes in verbal working memory with acute stroke

Functional imaging studies consistently find that older adults recruit bilateral brain regions in cognitive tasks that are strongly lateralized in younger adults, a characterization known as the Hemispheric Asymmetry Reduction in Older Adults model. While functional imaging displays what brain areas are active during tasks, it cannot demonstrate what brain regions are necessary for task performance. We used behavioral data from acute stroke patients to test the hypothesis that older adults need both hemispheres for a verbal working memory task that is predominantly left-lateralized in younger adults. Right-handed younger (age ? 50, n = 7) and older adults (age > 50, n =21) with acute unilateral stroke, as well as younger (n =6) and older (n =13) transient ischemic attack (TIA) patients, performed a self-paced verbal item-recognition task. Older patients with stroke to either hemisphere had a higher frequency of deficits in the verbal working memory task compared to older TIA patients. Additionally, the deficits in older stroke patients were mainly in retrieval time while the deficits in younger stroke patients were mainly in accuracy. These data suggest that bihemispheric activity is necessary for older adults to successfully perform a verbal working memory task.     

早期基督教习俗中的异教因素

随着基督教的成功崛起,许多异教习俗不是被完全抛弃,而是被逐渐地改造成为基督教习俗。基督徒的许多葬俗,都可以从异教世界的相关习俗中找到原型;基督徒的梦幻和异像,与异教梦兆密切相关;基督徒的许多重要节庆,也可以溯源到希腊罗马世界乃至遥远的东方。基督教习俗虽然与异教习俗有着千丝万缕的历史联系,但它绝不是后者的简单翻新,它在采用后者的某些形式的同时,必然也要赋予其全新的内容。早期基督教对异教习俗的广泛吸纳,说明了文化包容正是该教的一大显著特征。     

鼻窦炎鼻内镜术后术腔置药疗效分析

为了缩短鼻内镜手术病程,防治并发症,以2006年1月至200g年1月大连市中心医院耳鼻咽喉科127例鼻内镜术后患者为样本,其中64例患者(对照组)行常规术后鼻腔清理,另63例患者(实验组)常规清理后,术腔放置浸入辅舒良鼻喷雾剂的明胶海绵小块.对两组患者术后施行同样频度、同样疗程术腔清理,观察术腔上皮化的时间进行对比.结果术后随访6个月～12个月,实验组上皮化的时间明显早于对照组,差异有显著性(P<0.05).因此,此方法安全有效,简便易操作,明显缩短了病程,有利于减少或避免术后并发症.     

中外公务员医疗保障法律制度的比较研究

许多国家和地区对公务员提供比较专门的医疗保障待遇,如西班牙、韩国和日本.我国公务员在享受基本医疗保险以外,为了确保公务员医疗保障待遇不降低,我国建立了公务员医疗补助制度.通过对各国公务员医疗保障制度立法、保障经费来源及保障水平的比较,对我国完善公务员医疗保障制度提出了建议.     

对妊娠晚期畸形胎儿实施致死性引产的可行性分析

在妊娠晚期发现胎儿畸形,许多胎儿父母要求引产。一些患儿父母因为在医院引产出活体畸形婴儿而与医院产生纠纷。本文考虑采用医疗方法在引产前或引产中使胎儿心跳停止,确保引产出的胎儿为死婴（即致死性引产）以减少纠纷,利于社会。本文试图从医疗、伦理、法律的角度,探讨在胎儿父母要求下,对妊娠晚期畸形胎儿实施致死性引产的可行性。     

Acceptance and Commitment Therapy for generalized anxiety disorder in older adults: a preliminary report

Some evidence suggests that acceptance-based approaches such as Acceptance and Commitment Therapy (ACT) may be well-suited to geriatric generalized anxiety disorder (GAD). The primary goal of this project was to determine whether ACT was feasible for this population. Seven older primary-care patients with GAD received 12 individual sessions of ACT; another 9 were treated with cognitive-behavioral therapy. No patients dropped out of ACT, and worry and depression improved. Findings suggest that ACT may warrant a large-scale investigation with anxious older adults.     

Unbalanced triangle in the social dilemma of trust: Internet studies of real‐time,real money social exchange between China,Japan, and Taiwan

Using a dyadic game theory paradigm, three experiments on the social dilemma of trust were conducted over the Internet in real time, involving real money. It was predicted and found that in‐group favouritism in trusting behaviour was contingent on historical relationships between societies. In the China–Japan experiment, mainland Chinese but not Japanese trusted and made fair allocations to in‐group members more than out‐group members, and out‐group trust was best predicted by positive stereotypes of the out‐group for Chinese and identity for Japanese. In the China–Taiwan experiment, Taiwanese but not Mainland Chinese trusted in‐group members more than out‐group members, and in‐group trust for Taiwanese was best predicted by perceptions of current realistic threats. In the Taiwan–Japan experiment, there were slight in‐group favouring tendencies in trust, and positive stereotypes of the out‐group were the best predictors of out‐group trust. Japanese were unique in not displaying in‐group favouring behaviour at all, whereas both Chinese and Taiwanese were context specific in their in‐group favouritism. Stereotypes, social identities, perceptions of realistic threat, and historical anger made significant contributions to predicting trusting behaviour, but overall these survey measures only accounted for small and inconsistent amounts of variance across the three experiments.     

青少年社会认知复杂性与同伴交往的相关分析

社会认知复杂性是描述个体社会认知结构特点的个体差异变量,作为社会认知领域的研究热点,当前却鲜有研究关注它与同伴交往的关系。本研究选取初一至高二234名中学生考察了社会认知复杂性与同伴交往之间的关系,并辅以人际交往能力、学业成就通过结构方程模型进一步探讨了二者之间关联的路径。结果表明：（1）青少年社会认知复杂性与同伴接受、同伴拒绝、人际交往能力、学业成就之间存在显著相关。社会认知复杂性高的学生获得了较多的同伴接纳、较少的同伴拒绝,并具有较高的人际交往能力和学业成就。（2）青少年社会认知复杂性以人际交往能力和学业成就为中介变量间接影响同伴的受欢迎程度。     

留学经验与艺术创造力

采用两个艺术创造力测量任务比较了中国留学生、德国大学生和中国国内学生的艺术创造力水平。使用共感评价技术作为评判艺术作品创造程度、技术水平等维度的方法。研究发现:(1)在艺术创造力任务中,中国留学生没有表现出比中国国内学生的优势,说明可能多元文化经验对创造力表达的影响是有条件的;(2)德国学生的艺术创造力水平高于中国学生,本结果支持前人研究中有关个人主义文化相对于集体主义文化更有助于创造力表达的相关假设;(3)共感评价技术是艺术创造力研究的有效工具。
