コミュニケーション回避としての発言抑制発生機序モデルの検討 [PDF]
本研究は、坂本・プリブル・キートン(1998)のコミュニケーション回避に関する理論モデルを基に発言抑制に関する仮説モデルを構築し検証したものである。発言抑制に関する遺伝的素質として行動抑制系(BIS)、早期に作られる認知的機構として不合理な信念を想定し、それらによって生じる状態不安が発言抑制を発生させるという仮説の下、理論上時間的に先行する概念から現在の状態へとパス図の構成要素を配置し、因果関係を想定している。 170名の大学生に対する質問紙調査を実施した。因子分析の結果、大学生の発言抑制は ...

ABSTRACT Epidermal bioelectronics is a transformative technology for continuous health monitoring and human‐computer interaction. However, the mechanical and physiological mismatch at the skin–device interface limits its long‐term application. Electrospun nanofiber membranes (ENMs), with their unique three‐dimensional hierarchical porous network and ...

VFTO具有波前陡、幅值高、频带宽、持续时间长等特点,是GIS变电站及邻近电力设备安全的巨大威胁,必须采取措施对其进行抑制。现有的几种抑制方法均有一定的效果,也存在相应的缺陷。据此提出一种高频过电压抑制导线的设计。抑制导线由GIS母线改造的镂空螺线管及与之并联的电阻组成,安装方式与常规母线无异。在工频下,其正常进行电流、电压波的传输;当有高频过电压时,起抑制VFTO的作用。文中对高频过电压抑制导线抑制VFTO的机理进行了分析,说明了其抑制VFTO的优势。然后从抑制导线的结构分析其抑制VFTO的效果 ...
