"罗斯悖论"研究述评

道义逻辑作为广义模态逻辑的一个分支,它研究的是含有"应该"、"允许"、"禁止"等道义模态词的语句的逻辑特性及它们之间的推理关系.研究道义逻辑,无法回避"道义悖论"问题.作为20世纪50、60年代兴起的新兴学科,道义逻辑正是在与各种各样的"悖论"的交锋中发展的."道义‘悖论'是驳斥某些成问题的道义演算的有力武器,也是驳斥普通的道义语句所做的某种天真解释和分析的有力武器."[1]反过来,对"道义悖论"的分析也有助于认识、了解和促进道义逻辑的发展和完善.     

感染后咳嗽患儿血微量元素分析与黄芪注射液联合甘草合剂治疗研究

分析儿童感染后咳嗽的临床特点以及与外周血微量元素的关系,观察黄芪注射液联合甘草合剂治疗儿童感染后咳嗽的疗效.对自2006年1月至2008年6月在德州市妇幼保健院儿科门诊治疗的75例感染后咳嗽患儿行外周血微量元素测定,与40例健康小儿微量元素时比,并将75例患儿随机分为两个治疗组进行临床观察:实验组39例,口服黄芪注射液和甘草合剂联合治疗;对照组36例,口服阿奇霉素治疗;对比两组疗效,并在治疗前后行肝肾功检查,观察有无肝肾损害.75例患儿外周血铁、锌、镁均有不同程度的降低.实验组疗效优于对照组,治愈率分别为92.31%和75%,统计学处理χ2=4.17,P<0.05.治疗前后两组均未出现肝肾功损害.感染后咳嗽发病可能与患儿血中微量元素铁、锌、镁降低有关,黄芪注射液联合甘草合剂治疗儿童感染后咳嗽安全有效.

德州地区进展性缺血性脑卒中相关危险因素的研究

探讨进展性缺血性脑卒中(SIP)的相关危险因素.选择德州市人民医院1999年～2009年163例SIP患者,首先对18个变量行单因素分析,然后对阳性变量行多因素Logistic逐步回归分析,筛选SIP发生的相关危险因素.高血压史、感染、加拿大卒中量表(CNS)评分、高血糖、TG、纤维蛋白原、脑水肿、颈动脉粥样硬化性狭窄、同型半胱氨酸和D-二聚体10个变量与SIP发生显著相关(P<0.05);脑水肿、颈动脉粥样硬化性狭窄、高血糖、感染、高纤维蛋白原水平和同型半胱氨酸6个因素是SIP发生的危险因素.脑水肿、颈动脉粥样硬化性狭窄,高血糖、感染、高纤维蛋白原在SIP发生中具有重要作用,为临床治疗提供了理论依据.     

Gami-Chunghyuldan ameliorates memory impairment and neurodegeneration induced by intrahippocampal Aβ 1-42 oligomer injection

Soluble oligomeric forms of amyloid beta (AβO) are regarded as a main cause of synaptic and cognitive dysfunction in Alzheimer’s disease (AD) and have been a primary target in the development of drug treatments for AD. The present study utilized a mouse model of AD induced by intrahippocampal injection of AβO (10 μM) to investigate the effects of Gami-Chunghyuldan (GCD), a standardized multi-herbal medicinal formula, on the presentation of memory deficits and neurohistological pathogenesis. GCD (10 and 50 mg/kg/day, 5 days, p.o.) improved AβO-induced memory impairment as well as reduced neuronal cell death, astrogliosis, and microgliosis in the hippocampus. In addition, GCD prevented AβO-triggered synaptic disruption and cholinergic fiber loss. These results suggest that GCD may be useful in the prevention and treatment of AD.     

Emotional reactions to scandals: When does moral character make a difference?

A scandal can evoke public outrage when it is widely publicized and involves an individual who is perceived to have a high level of cultural representativeness. Two experiments showed that when the scandalous target's moral character was highlighted, emotional responses towards the target were least negative when the scandal was widely circulated and when the target was seen as a representative of his culture. These results suggest that when a cultural symbol is implicated in a widely‐circulated scandal, the negative emotions directed towards the scandalous individual can be alleviated when the public remains confident in his or her commitment to morality.     

背景音乐的节奏与歌词语言熟悉程度对驾驶行为和眼动的影响

摘要：采用3D模拟驾驶情景结合眼动技术探讨音乐节奏和歌词语言熟悉程度对驾驶行为和眼动规律的影响,研究结果表明：（1）驾驶经验对驾驶行为及眼动影响显著,新手与老手相比速度更慢、错误数更多;（2）音乐节奏对驾驶速度、眼跳和垂直搜索广度影响显著,快节奏与慢节奏相比,驾驶速度更快、平均眼跳距离更短、垂直搜索广度更短;（3）歌词语言熟悉程度对驾驶速度、错误数和平均注视时间影响显著,熟悉语言与陌生语言相比,驾驶速度更慢、错误数更多、平均注视时间新手更长,老手无影响。（4）节奏与语言共同影响驾驶过程中的水平搜索广度,陌生语言时快节奏的水平搜索广度高于慢节奏,熟悉语言时快节奏的水平搜索广度低于慢节奏。通过本实验,建议驾驶员在选择音乐时选择陌生语言歌词的音乐,音乐节奏则可视情况而定。     

Virtual/real transfer of spatial knowledge: benefit from visual fidelity provided in a virtual environment and impact of active navigation

The purpose of this study was to evaluate the effect the visual fidelity of a virtual environment (VE) (undetailed vs. detailed) has on the transfer of spatial knowledge based on the navigation mode (passive vs. active) for three different spatial recall tasks (wayfinding, sketch mapping, and picture sorting). Sixty-four subjects (32 men and 32 women) participated in the experiment. Spatial learning was evaluated by these three tasks in the context of the Bordeaux district. In the wayfinding task, the results indicated that the detailed VE helped subjects to transfer their spatial knowledge from the VE to the real world, irrespective of the navigation mode. In the sketch-mapping task, the detailed VE increased performances compared to the undetailed VE condition, and allowed subjects to benefit from the active navigation. In the sorting task, performances were better in the detailed VE; however, in the undetailed version of the VE, active learning either did not help the subjects or it even deteriorated their performances. These results are discussed in terms of appropriate perceptive-motor and/or spatial representations for each spatial recall task.
