消化性溃疡的临床流行病学

消化性溃疡是消化系统常见多发病,20世纪在此领域有两个重要的发现,即有效的抑酸药质子泵抑制剂和幽门螺杆菌的发现,对其过去几十年的发病率和死亡率产生了巨大影响。尽管有了重大进展,这种疾病仍然是当前一个重要的临床问题,主要是因为越来越多的广泛使用非甾体抗炎药(NSAID)和低剂量阿司匹林药物。本文从流行病学角度来纵观其近年来的发病情况及其特点,以提供给同道参考。     

酒依赖与酒文化

在医疗过程中,无法取得患者的同意时,通常由他人代其做出同意。但是,代为同意人在代为做出同意时,必须以患者本人的最佳利益为原则。在判断患者的最佳利益时,可以借鉴英国《心智能力法2005》的规定,通过对诸因素的评估,来综合决定何谓患者的最佳利益。我国在制订和修改代为同意的相关规定时,应该考虑如何借鉴英国的规定,制订符合我国国情的代为同意制度。     

CULTURE AND WORK ORGANIZATION: THE CHINESE CASE *

This paper discusses the role of the indigenous values in facilitating the development of managerial and organizational systems underlying the success of indigenous enterprises in the newly industrialized societies. One illustration is the Chinese culture or, more specifically, the Confucian tradition and ethos, and their implication for management and worker performance in work organizations within the ‘Confucian league’ of Asian societies. The affective rational approach to the paternalistic style of the Japanese and Chinese management coupled with such normative values as trust, subtlety and loyalty of the employees explain the individuals' commitment to their work organization and the excellence in leadership. With reference to the leading steel plant, the China Steel Corporation in Taiwan, this paper examines how such a cherished system of managerial philosophy and practices, in the context of its indigenous Chinese cultural and normative heritage, has been successfully applied to the integration of its labour force, and the upgrading of their morale, performance and productivity.     

上博简《仲弓》疏证

上海博物馆藏战国楚竹书第三册《仲弓》,是一篇久佚的先秦儒家文献,它对于我们认识孔子的政治理论和了解《论语》成书的一些情况,都有比较重要的价值。本文对于《仲弓》篇的28支简的简序进行了重新编排,并且分段进行了疏证研究,探讨了孔子政治思想中的若干重要内容。     

比较视觉搜索任务中工作记忆最小化的眼动研究

采用比较视觉搜索任务和眼动追踪技术,通过增加组成图片的图形数量和改变不同图形的特征属性,考察比较视觉搜索任务是否遵循工作记忆最小化原则以及图形特征加工的优先性问题。结果表明图形数量的增加不影响平均每次注视的图形数量,被试平均每次注视1.65个图形,即比较视觉搜索任务仍遵循工作记忆最小化原则。不同图形中颜色和形状都不同的注视时间最短,颜色不同和形状不同在注视时间上差异不显著,表明比较视觉搜索任务中特征维度数量比特征性质在引导注意上具有优先性。事先不规定搜索路径的情况下,被试主要采用系统搜索策略完成比较搜索任务。     

Connectedness underlies the underestimation of the horizontal vertical illusion in L-shaped configurations

L-shaped configuration is a commonly used stimulus configuration in studying horizontal vertical illusion. Here, we report that the horizontal vertical illusion is substantially underestimated when the L-shaped configuration is used for evaluating the illusion. Experiment 1 found that, in a length perception task, the perceived length of a vertical bar was about 10% longer than that of a horizontal bar with the same physical size. Similar amount of HVI was found in a length comparison task, in which the length of a horizontal bar was compared to that of a vertical bar and the two bars were presented separately in space or in time. In contrast, when the length comparison task was conducted with the two bars being arranged in a connected L-shape, the illusion was halved in strength. Experiment 2 and 3 studied what might be the cause of this L-shape induced HVI-underestimation. Two factors were investigated: the connectedness of the two lines, and the 45° absolute orientation or the 45° inner angle information embedded in the upright isosceles L-shape. The results showed that the HVI strength was not much affected when the 45° absolute orientation and the 45° angle information was made useless for the length comparison task. In contrast, the illusion was significantly reduced in strength whenever the two lines were separated as compared to when they were connected. These results suggested that the connectedness of the two lines must underlie the underestimation of the horizontal vertical illusion in the L-shaped configurations.     

家电销售人员胜任特征模型建构

本研究旨在探讨优秀家电销售人员应具备的胜任特征。首先通过对20名家电销售人员的行为事件访谈,初步构建了家电销售人员胜任特征模型;然后通过对20例顾客与家电销售人员的互动进行自然观察,进而对所建构的模型加以验证。研究表明,家电销售人员胜任特征模型共包括9项:成就导向、主动性、学习发展、影响力、洞察力、服务意识、可信赖、情绪稳定性以及产品知识。     

字词认知N170成分及其发展

字词认知早期的N170成分是第一个对语言材料敏感的成分.最近对字词认知N170成分的研究主要集中在探讨其敏感性、偏侧化以及此成分的发展变化.大量研究认为字词N170成分的敏感性与正字法加工有关,但也有一些研究认为其受语音、语义调制.对于此成分的偏侧化研究结果较一致认为是左侧化.最近的发展研究对N170成分进行探讨,取得了一些成果.在剖析现有研究基础上,本文认为应对字词认知N170成分的偏侧化、功能分离等问题进行深入研究.     

现实预期与意愿预期在文本阅读中的保持

文本阅读中, 读者往往对事件的后续发展进行预期推理。预期推理有两种倾向, 要么是倾向于根据客观现实条件进行的现实预期, 要么是倾向于根据主观的个人意愿进行的意愿预期。3个实验通过自定步调阅读范式探讨了文本阅读中读者产生的现实预期和意愿预期的保持。结果发现, 现实预期和意愿预期在长时记忆中的保持情况差异明显, 现实预期不能在长时记忆中保持, 而意愿预期则能保持; 但意愿预期也不能单独存在, 会受到现实条件的制约, 在受到现实否定后即时消退, 不再影响读者的进一步阅读。     

企业员工组织政治认知量表的构建
