Construct Validation of the Dutch Version of the Impact of Event Scale.

The Impact of Event Scale (ES; M. J. Horowitz, N. Wilner, & W. Alvarez, 1979) is a worldwide-used self-report measure to assess the frequency of intrusive and avoidant phenomena after a variety of traumatic experiences. The purpose of this article is to assess the psychometric value of the Dutch version of the IES (D. Brom & R. J. Kleber, 1985) in several samples of individuals who had experienced various traumatic stressors. The reliability and structure of the IES were evaluated in 3 different samples (total N = 1.588). The reliability of the Dutch version of the IES was adequate across the various stressors. The construct validity was assessed by using confirmatory factor analyses. Outcomes revealed a robust structure over the various samples, generally supporting the composition of the original IES. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Cooperative transaction hierarchies: Transaction support for design applications

Traditional atomic and nested transactions are not always well-suited to cooperative applications, such as design applications. Cooperative applications place requirements on the database that may conflict with the serializability requirement. They require transactions to be long, possibly nested, and able to interact with each other in a structured way. We define a transaction framework, called acooperative transaction hierarchy, that allows us to relax the requirement for atomic, serializable transactions to better support cooperative applications. In cooperative transaction hierarchies, we allow the correctness specification for groups of designers to be tailored to the needs of the application. We usepatterns andconflicts to specify the constraints imposed on a group's history for it to be correct. We also provide some primitives to smooth the operation of the members. We characterize deadlocks in a cooperative transaction hierarchy, and provide mechanisms for deadlock detection and resolution. We examine issues associated with failure and recovery.

蓝鲸备份系统

业务的全球化使得备份窗口逐渐缩短,如何快速有效地对数据进行统一备份成为数据保护领域亟待解决的关键问题之一。该文设计并实现了一个基于块级备份的分布式数据备份系统(蓝鲸备份系统)。该系统采取块级备份方式,对于不同的文件系统或数据库,都可以采取统一方式进行备份。同时,块级备份能提供更细粒度的备份,与文件级备份相比,在备份性能和空间利用率上都得到了很大提高。蓝鲸备份系统采取策略驱动的自动备份,实现了管理的自动化。

激光视觉融合下的运动检测与失配矫正

针对单一传感器在动态场景感知问题上的局限性,设计了一种融合激光与视觉的实现系统,并对运动检测中的背景显露区误判问题和融合中不同传感器间点云的失配问题分别提出了改进算法。在运动检测上,首先基于视觉的背景差分算法对激光进行前景点分拣,再以激光前景点为启发信息进行视觉前景聚类。在融合失配问题上,首先基于栅格失配度分别对激光和视觉点云进行聚类分割,再以激光为基准,逐一将对应的视觉点云与之配准,滤除噪声后所得到的矫正点云可用于场景重建进行进一步验证。实验结果表明,改进算法所获得的融合前景对"影子"有更好的鲁棒性;较之整体配准的矫正,改进算法在平均失配度上降低了约75%,在y和z方向上的偏移比收敛了至少5%。     

GH36合金中M23C6、VC的界面结构

使用透射电镜观察了GH36合金中M₂₃C₆、VC碳化物和基体之间的界面结构,在M₂₃C₆/γ的半共格界面上分布有错配位错列,间距约10nm。根据${\\rm{\\vec g}}$·${\\rm{\\vec b}}$=0判据,可以确定该位错的Burgers vector ${\\rm{\\vec b}}$=a/2(110)γ,VC/γ的相界面是具有很大点陈错配度(δ=+0.155)的共格界面。最后,从M₂₃C₆、VC和基体之间的不同界面结构与性质讨论了以碳化物沉淀为主要强化手段的Fe基GH36合金的强韧化本质以及如何识别波纹图(Moire pattern)和界面位错的问题。

Further Validity Evidence for the Teacher Version of the Child Symptom lnventory-4.

The reliability and validity of the teacher version of the Child Symptom Inventory-4 (CSI-4) was examined in 248 boys referred for evaluation of behavioral and emotional problems. The CSI-4 is a behavior rating scale whose items correspond to the symptoms of DSM-IV-defined disorders. The results indicated satisfactory internal consistency reliabilities for most symptom categories, and CSI-4 scores converged and diverged in a theoretically consistent manner with respective scales of the Teacher's Report Form (Achenbach, 1991), the IOWA Conners Teacher's Rating Scale (Loney & Milich, 1982), and the Diagnostic Interview for Children and Adolescents-Revised Parent Version (DICA-P; Reich, Shayka, & Taibleson, 1991). Correlations between teacher and parent CSI-4 ratings were low to moderate, whereas all correlations between teacher ratings and child self report were very low (rs     

Screening for posttraumatic stress disorder: An evaluation of two self-report scales among crime victims.

The validity of the Impact of Events Scale (IES) and the Posttraumatic Stress Disorder (PTSD) Symptom Scale, Self-Report version (PSS-SR) was examined among crime victims. Both instruments performed well as screeners for PTSD. For the IES, sensitivity ranged between .93 and 1.00; for the PSS-SR, sensitivity ranged between .80 and .90. Specificity for the IES ranged between .78 and .84 and for the PSS-SR ranged between .84 and .88. Some individual items from the 2 scales performed just as well as the total scales. The authors conclude that either of these short self-report instruments or their individual items are suitable as screeners for PTSD, specifically in settings where mental health professionals are unavailable. Cross-validation of these results is necessary because of the small sample size in this study. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
