达米特论意义和真

达米特的反实在论意义理论在当代语言哲学中占据重要地位.本文主要分析了他对"意义"和"真"这两个概念的解释,指出他的意义理论完全是一种形式说明,或者说,是对意义理论本身的形式构造.同时,达米特反对用真值条件来解释意义,主要是根据他对"真"这个概念有着不同的理解:他把"真"看作我们在具体场合说出的句子的属性.达米特的思想受到了各方面的批评,他也在这种批评和反批评过程中不断完善自己的思想.     

Improving computer skill training: behavior modeling, symbolic mental rehearsal, and the role of knowledge structures

Effective computer skill training is vital to organizational productivity. Two experiments (N = 288) demonstrated that the behavior modeling approach to computer skill training could be substantially improved by incorporating symbolic mental rehearsal (SMR). SMR is a specific form of mental rehearsal that establishes a cognitive link between visual images and symbolic memory codes. As theorized, the significant effects of SMR on declarative knowledge and task performance were shown to be fully mediated by changes in trainees' knowledge structures. The mediational role of knowledge structures is expected to generalize to other training interventions and cognitive skill domains. Our findings have the immediate implications that practitioners should use SMR for improving the effectiveness of computer skill training.     

Inhibition of return to occluded objects

Since many visual objects are vulnerable to occlusion, an active process that tracks objects behind occluders confers considerable ecological validity to the visual system. We studied this possibility by testing whether inhibition of return can be observed with occluded objects. In our experiments, two moving objects disappeared or reappeared behind occluders while a cue and a probe were presented. Contrary to the results of a previous study (Tipper, Weaver, Jerreat, & Burak, 1994), responses were consistently delayed for the cued object that was occluded when it was cued (Experiment 1), when it was probed (Experiment 2), or both (Experiment 3). These results suggest that attention can select occluded objects that are out of view. Our findings are in line with prior studies that have demonstrated similar perceptual/attentional effects for occluded objects, as well as for visible objects.     

当代大学生创业意向影响因素研究

为了深入了解当代大学生的创业意向及其影响因素,研究者以全国30所高校5000多名大学生为被试,对影响大学生创业意向的诸多因素进行了分析。研究发现:当代大学生的创业意向在性别、奖学金获得次数、学生干部经历、出生地上均存在一定差异。大学生主客观条件中的性别、学校性质、创业兴趣、创意能力改善对创业意向有显著影响。创业教育和创业环境认知的引入对于预测大学生的创业意向均有增量效度,能够在个体的主客观条件以外解释个体创业意向的变异。在大学生认知中,影响创业成功的因素主要由客观背景资源、主观能力经验和外部宏观环境3个因子组成,其中主观能力经验的作用排在首位。     

论维特根斯坦的“哲学语法”概念

<正>近些年来,国内外哲学界在维特根斯坦思想研究中,逐渐关注到维特根斯坦的"哲学语法",特别是试图从当代哲学的视角解读他的语法概念的思想内容。(Forster;陈嘉映;韩林合,第11章)我在阅读过程中发现,维特根斯坦对"语法"概念的使用完全不像我们想象的那样严格,而如何理解其"哲学语法"概念,实际上意味着如何理解维特根斯坦哲学。     

传统药物治疗认识误区几点浅析

药物是治疗疾病的物质基础,传统药物治疗认识中的许多误区影响人们对疾病的合理治疗.积极宣传药物治疗新理念,普及现代药学知识和理论,提高广大人民群众对药物治疗的认识水平,是避免出现药物治疗认识误区的主要手段.应加强宣传力度,带领群众走出误区,促进合理用药.     

加强麻醉科本科实习生对手术患者围术期心理支持疗法的培养

麻醉科本科实习生在实习期间必然面对众多的手术患者,我院欲将这些学生培养成合格的、德才兼备的医生,除了在实习期间指导他们掌握专业理论和实践技能外,更要加强他们对临床手术患者人文关怀意识的培养.手术患者的焦虑情绪往往影响麻醉管理质量,甚至预后;加强实习生对手术患者围术期心理支持疗法的培养意义深远.     

宗教与全球发展:一种对话路径

宗教与全球发展成为当代社会的一个重要议题,一个标志在于联合国千禧年发展目标的提出及世界宗教和精神领袖千禧年和平高峰会议。其中,由前世界银行行长及当时的坎特伯雷大主教联合发起的世界信仰发展对话,即为推动类似目标的一个重要机构。发展的目的在于人。贫困不仅包括物质的层面,也包括精神的层面。全球经济的发展需要一种伦理和价值的支撑。文化应该作为一种创新机制,参与并影响全球发展的过程。在中国,宗教是建设社会主义和谐社会的重要因素。中共十七大明确指出,要发挥宗教在社会经济发展中的重要作用。十七届六中全会则明确提出文化体制改革的目标。随着中国改革开放的进一步深入,中国对世界的影响日益加强,文化和精神的维度在社会发展和国家建设方面将扮演更重要的作用。中国模式也将对世界论坛的讨论产生一定影响。     

Spatial orienting in the visual field: a unified perceptual space?

Visual attention can be oriented toward a spatial location in the visual field exogenously by an abrupt onset of a peripheral cue. In a series of behavioral studies on exogenous orienting of attention with a double-cue paradigm, we demonstrated a functional subdivision of perceptual space in the visual field. Specifically, inhibition of return (IOR) is much stronger at periphery relative to perifoveal visual field up to approximately 15° eccentricity, suggesting two dissociable functional areas in the visual field. To further investigate the generality of this functional subdivision of the visual field, we measured IOR effects with another single-cue paradigm and applied a very short cue-target interval that was typically anticipated not to observe any inhibitory effect at all. Consistent with this expectation, no IOR effects at the eccentricities up to 15° were observed. However, significant IOR effects beyond 15° eccentricities were consistently demonstrated. These results not only revealed an early onset of IOR for more peripheral stimuli, but also confirmed that the perceptual space in the visual field is not homogeneous but underlies a functional subdivision with a border of ca. 15° eccentricity.     

Brueckner and Fischer on the Evil of Death

A primary argument against the badness of death (known as the Symmetry Argument) appeals to an alleged symmetry between prenatal and posthumous nonexistence. The Symmetry Argument has posed a serious threat to those who hold that death is bad because it deprives us of life’s goods that would have been available had we died later. Anthony Brueckner and John Martin Fischer develop an influential strategy to cope with the Symmetry Argument. In their attempt to break the symmetry, they claim that due to our preference of future experiential goods over past ones, posthumous nonexistence is bad for us, whereas prenatal nonexistence is not. Granting their presumption about our preference, however, it is questionable that prenatal nonexistence is not bad. This consideration does not necessarily indicate their defeat against the Symmetry Argument. I present a better response to the Symmetry Argument: the symmetry is broken, not because posthumous nonexistence is bad while prenatal nonexistence is not, but because (regardless as to whether prenatal nonexistence is bad) posthumous nonexistence is even worse.
