Systematic studies of modified vocalization: speech production changes during a variation of metronomic speech in persons who do and do not stutter

The most common way to induce fluency using rhythm requires persons who stutter to speak one syllable or one word to each beat of a metronome, but stuttering can also be eliminated when the stimulus is of a particular duration (e.g., 1 second [s]). The present study examined stuttering frequency, speech production changes, and speech naturalness during rhythmic speech that alternated 1 s of reading with 1 s of silence. A repeated-measures design was used to compare data obtained during a control reading condition and during rhythmic reading in 10 persons who stutter (PWS) and 10 normally fluent controls. Ratings for speech naturalness were also gathered from naïve listeners. Results showed that mean vowel duration increased significantly, and the percentage of short phonated intervals decreased significantly, for both groups from the control to the experimental condition. Mean phonated interval length increased significantly for the fluent controls. Mean speech naturalness ratings during the experimental condition were approximately “7” on a 1–9 scale (1 = highly natural; 9 = highly unnatural), and these ratings were significantly correlated with vowel duration and phonated intervals for PWS. The findings indicate that PWS may be altering vocal fold vibration duration to obtain fluency during this rhythmic speech style, and that vocal fold vibration duration may have an impact on speech naturalness during rhythmic speech. Future investigations should examine speech production changes and speech naturalness during variations of this rhythmic condition.Educational objectives: The reader will be able to: (1) describe changes (from a control reading condition) in speech production variables when alternating between 1 s of reading and 1 s of silence, (2) describe which rhythmic conditions have been found to sound and feel the most natural, (3) describe methodological issues for studies about alterations in speech production variables during fluency-inducing conditions, and (4) describe which fluency-inducing conditions have been shown to involve a reduction in short phonated intervals.     

综论中国地方政府职能转变与机构改革

科学界定地方政府职能取决于纵向——中央-地方政府权力关系架构下的权责划分和横向——不同时代条件下政府属性及其行为取向这两个维度变量的影响。本文基于经济学公共品理论的研究视角,构建了一个以地方层次上的外部性和规模经济构成的二维空间,以此作为中央-地方政府职能划分的判断矩阵,并进一步简要分析了中国地方政府机构改革取向。本文认为,中国地方政府机构设置与中央政府有同有异理应是主流政策取向。具体而言,省级政府可能最为接近中央政府的模式,地市级政府可能更偏向于因地制宜的模式,而县、乡级政府将趋于功能整合、部门精简,一如缩微版的大部制。     

身心二元论的困境与具身认知研究的兴起

摘要 由笛卡尔开创的身心二元论一直制约着人们对身心关系的认识。但是近年来兴起的具身认知研究却从理论和实证的角度系统论证了二元论的不可能性,指出了心智对身体的依赖性,并据此提出了身心一体的身心关系学说。最初,有关具身认知的讨论仅仅是哲学领域有关身心关系问题的形而上学思考,随后开始成为心理学中的一种理论思维,并逐步进入实验心理学领域。如今,ERP、FMRI等认知神经科学的手段在具身认知的研究中得到了广泛使用。具身认知已成为心理学和认知科学中的一股汹涌澎湃的实证研究思潮。     

A Comparison of a Subjective and Statistical Method for Establishing Score Comparability in an Organizational Culture Survey

Purpose

The purpose of this study was to compare the results of a subjective and a statistical method of detecting non-comparable items in 14 language-translated forms of a survey measuring organizational culture.

Design/Methodology/Approach

Data were obtained from a large multinational organization using a 60-item organizational culture survey. Each of 14 language-translated forms were administered to members of their respective language groups and compared to the original English (United States) form. Subjective reviews were conducted using fluent bilingual organizational members whom flagged items they did not believe were comparable. Statistical analyses using an item response theory (IRT) approach were used to detect problematic items from 14 samples with sizes ranging from 304 to 3,014. Detection patterns from these two approaches were compared.

Findings

The subjective approach identified far less items as problematic and did not agree with the statistical approach.

Implications

Our results suggest that the subjective approach as a pre-screening adaptation procedure has little added value over a careful translation/back-translation procedure.

Originality/Value

The use of language-adapted organizational surveys has become increasingly important to multinational organizations. In examining scores from such surveys the establishment of score comparability is essential. IRT analyses are often used to determine whether scores are comparable across language translations. It is also common for subjective reviews of item content to be utilized prior to statistical techniques to determine if the translated items are comparable to the original form. No research known to authors has compared modern statistical and subjective approaches to addressing these issues.     

人有“希望”的权利———围绕着康德“至善”的理念

本文从康德"批判哲学"的整体角度出发,在"思辨理性"和"实践理性"各自"立法权限"的关系中重点探讨了"德性"与"幸福"作为"原因"与"结果"的"先天综合"的可能性,以此阐明"希望"的"先天必然"的"根据",阐明"希望"之"权利"的"必然"基础。在面对"圆满之善"之为"希望"的"目的-对象"的问题时,本文还讨论了康德关于"神之存在"和"灵魂不朽"作为"实践理性""设定-悬设"所产生的问题,并试图提出自己的看法,强调一个在"实践理性""自律"下的"希望"的"理性"自身的"根据"。     

情绪和框架效应对个体捐赠决策影响的实验研究

本研究采用双因素被试间实验具体考察了特定即时情绪和框架效应对于捐赠决策的影响,结果发现存在显著的主效应和交互作用。悲伤情绪能够增加捐赠者的捐赠意愿,快乐情绪会降低捐赠者的捐赠意愿;损失框架能够增加捐赠者的捐赠意愿,幸存框架会降低捐赠者的捐赠意愿;快乐情绪的捐赠者的捐赠决策受框架效应的影响要弱于中性情绪和悲伤情绪的捐赠者,捐赠者在幸存框架下的捐赠决策受情绪的影响比在损失框架下受情绪的影响更小。     

预期背离下奖励与惩罚的ERPs研究

采用Flanker范式,通过事件相关电位(ERPs)技术,探讨预期背离情境下的脑电反应及与敏感性个体的关系。选取17名被试,采取2×2组内设计刺激类型（奖励vs.惩罚）和预期受挫（是vs.否）;结果表明（1）预期受挫情境引发更高的FRN;（2）惩罚刺激引发更高的FRN,奖励刺激引发更高的P3;（3）惩罚敏感与惩罚、无奖励情境引发FRN相关。本实验结果表明（1）FRN既反应对反馈效价的加工,也可能是预期背离的一种表现;（2）无奖励刺激受惩罚系统调节;无惩罚刺激受奖励系统调节。

书院:明代心学建构与传播的主要依托

明代心学是批判程朱理学的产物。不但心学的建构是与书院密切关联的,而且面对官方的禁学,心学的代表人物及其门人纷纷创建、修复书院以传播心学,使心学成为明代的显学。为解决书院研究、传播心学与教授科举应试知识的矛盾,心学家主张将书院应试教育与传播心学结合起来,二者互为表里,使书院在研究、传播心学过程中发挥更大的作用。     

未来中国马克思主义哲学

中国马克思主义哲学研究的未来走向,与过去和现在的研究现状密切相关,必然受多种因素的制约,主要是:马克思主义哲学中国化的传统、时代与时代主题、中国现代化建设的历史进程、世界性的哲学交流与对话等等。论文就相关问题,如哲学与政治、学术性与现实性、理论与实践、哲学与群众、主流学派与非主流学派、革命家与哲学家、哲学研究方式与实证研究方式等进行讨论。论文的结论:中国化的马克思主义研究将仍然是主流,过去哲学研究那种大一统的局面将不复存在,多样性的研究、主流学派与非主流学派并存,在建设中国特色的社会主义中,各种研究路径互相竞争、互相切磋、互相促进,未来中国马克思主义哲学研究将会出现前所未有的繁荣
