More decidable instances of Post's correspondence problem: beyond counting

We present a new technique to decide or reduce instances of Post's correspondence problem. It generalizes balance arguments to a consideration about some special context-free languages which allow the combination with other decision (or reduction) techniques. In spite of its simplicity, the new technique is able to decide more instances than known techniques.     

An empirical examination of application frameworks success based on technology acceptance model

Framework-based development is currently regarded as one of the most promising software development approaches when it comes to improvements in lead time, productivity and quality. However, many frameworks and projects based on frameworks still report failures, which indicate that there are problems related to both frameworks technology and frameworks usage. The objective of our research was to examine the major drivers that have an impact on a framework’s acceptance and a framework’s success. We used the technology acceptance model (TAM) and Seddon’s information systems success model as our underlying theory. Data collected from an online survey of 389 active framework users was used to test hypothesized models. Data analysis was performed via structural equation modeling. Our findings support the post-adoption version of TAM and the relationship between continuous use and the successful use of systems, where more use also means more net benefits. We found that the successful use of frameworks is mainly dependent on two factors: continuous framework usage intention and the perceived usefulness of the framework. Several practical and theoretical implications can be foreseen including advances in framework development guidelines and insight into the relationship between the acceptance and success of frameworks.

The benefits of being present: Mindfulness and its role in psychological well-being.

Mindfulness is an attribute of consciousness long believed to promote well-being. This research provides a theoretical and empirical examination of the role of mindfulness in psychological well-being. The development and psychometric properties of the dispositional Mindful Attention Awareness Scale (MAAS) are described. Correlational, quasi-experimental, and laboratory studies then show that the MAAS measures a unique quality of consciousness that is related to a variety of well-being constructs, that differentiates mindfulness practitioners from others, and that is associated with enhanced self-awareness. An experience-sampling study shows that both dispositional and state mindfulness predict self-regulated behavior and positive emotional states. Finally, a clinical intervention study with cancer patients demonstrates that increases in mindfulness over time relate to declines in mood disturbance and stress.

伦理与心理、品德与性格关系辨析

伦理学与心理学在学科渊源上是一家。个性心理结构中的核心组成部分即性格就是品德。品德体现人的社会性,即人的本质,它主导个人个性心理。在强调思想政治品德教育的前提下,应该认真落实学生的心理健康教育和心理咨询。     

基于对潜防御航母编队反潜舰阵位配置模型

基于航母编队对潜防御建立反潜舰阵位配置模型,需要立足于拖曳线列阵声纳使用和航母编队作战特点。 针对拖曳线列阵声纳使用,提出相邻反潜舰最小间距确定方法和弥补盲区措施;针对反潜舰在航渡和综合作战区中 承担的任务,运用解析法建立反潜舰阵位配置模型。在此基础上,通过设定合理参数进行仿真分析验证模型。结果 表明,该模型能为航母编队反潜舰阵位配置提供理论参考。

学修视角下的中国汉传佛寺空间格局研究——由三个古代佛寺平面所引起的思考

本文以汉传佛寺空间格局为主要研究对象,从“学修体系-建筑载体”互动关系这-新视角。以“教育目标-学修体系-组织方式及管理制度-建筑空间格局”这一逻辑演进的脉络为研究模型。对中国汉传佛教不同历史时期的典型佛寺类型如“道宣式”、“百丈式”、“后百丈式”等。进行了梳理和研究。这一研究,是让活的人的因素重新回归佛寺建筑研究。是一种“正本清源”式的思路,成为理解古今佛寺空间格局嬗变的一把钥匙。
