脊柱结核个体化综合治疗的思考

近年来脊柱结核迅速增多,严重威胁着人类的健康。本文分析目前脊柱结核治疗中存在的问题,围绕这些问题,从脊柱结核的化疗、手术、围手术期处理、术后督导治疗方面综合思考个体化综合治疗在脊柱结核中的应用。通过这些分析和思考,以期引导我们用系统全面的观点治疗脊柱结核,并最终控制其流行。     

中小学生阅读不同配图课文的眼动研究

使用ASL-4200R型眼动仪,采用3×2×2的三因素混合设计,对77名中小学生阅读不同配图课文进行了考察。结果表明:(1)中小学生阅读不同配图难度课文的阅读成绩、阅读时间等阅读理解指标,以及注视频率、注视点持续时间和眼跳距离等眼动指标具有明显的年龄特征;(2)中小学生阅读不同配图课文的阅读成绩、阅读时间和阅读速度等阅读理解指标,以及注视次数和回视次数等眼动指标具有显著差异,示意图组显著优于实景图组;(3)中小学生阅读不同难度课文的注视频率和回视次数对阅读过程有非常显著的影响,易课文显著优于难课文。     

大学应当提供什么样的人文教育--从《大学人文读本》之旨趣谈起

本文从夏中义先生主编的《大学人文读本》的旨趣入手,考察了中西方关于人文一词的来源及涵义,认为人文的内涵是随着人对宇宙人生的真理和价值的认识而不断加深和丰富的,大学的人文教育则旨在型塑人对自身在宇宙中的地位、意义和价值的觉解,人的丰厚蕴涵、独特自我、高尚人格、高雅品德,以及人与人、人与社会、人与自然的良性关系。由此反思了《读本》的缺弊,并为中国大学的人文教育提出一愿景。     

小学生有意遗忘中认知抑制能力发展的研究

有意遗忘是一种新的关于记忆研究的实验范式．主要探讨个体抑制能力的发展。研究使用的实验材料分为单字和双字词．被试为小学二、四、六年级共90名学生。实验结果发现：①对于两种实验材料单字和双字词,小学生有意遗忘中的认知抑制能力随年级而提高;②小学生对两种材料的抑制能力存在差异,表明小学生在有意遗忘中的抑制能力受材料的意义性和材料难度的影响。

Discrimination and memory experiments on haptic perception of softness

This paper described a pilot study and two follow-up experiments, using a device developed in the laboratory to study the human fingertip's discrimination and memory for softness perception. According to the pilot study, soft objects were easier to identify than hard ones. When subjects touched objects, the number of times seemed to be from 2 to 6. For most, the touch frequency ranged from 0.3 to 1.3 Hz. In Exp. 1, the method of constant stimuli was used to study the human fingertip's stiffness difference threshold for haptic perception. The estimated difference threshold averaged over 24 subjects was 33 N/m. And, the stiffness difference thresholds for most people were in the range of 20 N/m to 40 N/m. In Exp. 2, the haptic memory span was discussed according to the recall experiment. Human haptic memory span lay between three and four items.     

Relationship between upper extremity kinesthetic sense and writing performance by students with low vision

Kinesthetic sense plays an important role in writing. Children with low vision lack sensory input from the environment given their loss of vision. This study assessed the effect of upper extremity kinesthetic sense on writing function in two groups, one of students with low vision (9 girls and 11 boys, 9.4 +/- 1.9 yr. of age) and one of sighted students (10 girls and 10 boys, 10.1 +/- 1.3 yr. of age). All participants were given the Kinesthesia Test and Jebsen Hand Function Test-Writing subtest. Students with low vision scored lower on kinesthetic perception and writing performance than sighted peers. The correlation between scores for writing performance and upper extremity kinesthetic sense in the two groups was significant (r = -.34). The probability of deficiencies in kinesthetic information in students with low vision must be remembered.     

Tight and loose are not created equal: An asymmetry underlying the representation of fit in English- and Korean-speakers

Research concerning the spatial dimension fit (tight versus loose) has been based on a tacit but untested assumption that the dimension fit is symmetrical, with tight- and loose-fitting relations highlighting the dimension fit with equal force. We propose a reformulation, documenting that adult speakers of English (Experiment 1) and Korean (Experiment 2) are sensitive to the dimension fit, but that their representation is asymmetric, with tight-fitting events highlighting fit with greater force than loose-fitting events. We propose that sensitivity to the dimension fit is more resilient than has previously been suggested, and that the asymmetry documented here provides a foundation upon which to pursue nuanced questions about the relationship between language and our underlying representations of space.     

Are facilitated mentoring programs beneficial? A randomized experimental field study

Results from a pretest–posttest randomized field experiment study with a control group comparing the impact of high- and low-level-facilitated mentoring programs on new employees’ performance and perceptions about their jobs and organization were reported in this paper. Results indicated increases in job satisfaction, organizational commitment, person-organization fit and performance by participants in both mentoring programs with larger gains made by the high-level-facilitated group. These results suggest that a formal mentoring program can have positive effects on employee’s work-related attitudes, cognition and behavior with significantly greater gains made by formal mentoring programs with higher levels of facilitation.     

项目特异性加工和关系加工对非熟练中-英双语者跨语言错误记忆的影响

采用DRM范式进行跨语言错误记忆的研究较为鲜见, 而且得出了许多不同的结果, 关于错误记忆跨语言产生的理论解释也是各执己见。研究以非熟练中-英双语大学生为被试, 采用DRM范式对非熟练中-英双语者的跨语言错误记忆进行了研究。在2个实验中, 分别探讨了项目特异性加工和关系加工条件下, 语义激活的不同水平对跨语言错误记忆的影响。结果发现：1)非熟练中-英双语者也存在跨语言的错误记忆; 2)在项目特异性加工和关系加工条件下, 相同语言内与不同语言间发生关键诱词的错误再认的结果是不同的; 3)只在项目特异性加工条件下, 长词表比短词表会诱发更多的对关键诱词的错误再认。研究结果支持了激活-监测理论。
