EMDR Therapy Following the 9/11 Terrorist Attacks: A Community-Based Intervention Project in New York City.

This article presents the results of a time-limited psychological relief effort using eye movement desensitization and reprocessing (EMDR) following the attacks on the World Trade Center on September 11, 2001. Clients made highly significant positive gains on a range of outcome variables, including validated psychometrics and self-report scales. Analyses of the data suggest 2 broad conclusions: EMDR is a useful treatment intervention both in the immediate aftermath of disaster as well as later; the longer treatment is delayed, the greater the level of disturbance experienced by clients. Also discussed are problems in conducting research during mass disaster response situations. A demonstration of an analog to a wait-list control group is provided.

Memory and Emotions for the September 11, 2001, Terrorist Attacks in Patients With Alzheimer's Disease, Patients With Mild Cognitive Impairment, and Healthy Older Adults.

National traumatic events can produce extremely vivid memories. Using a questionnaire administered during telephone interviews, the authors investigated emotional responses to, and memory for. the September 11, 2001, terrorist attacks in patients with Alzheimer's disease (AD), patients with mild cognitive impairment (MCI), and healthy older adults in the initial weeks following the event and again 3-4 months later. There were several notable findings. First, patients with AD showed less memory than patients with MCI and older adults. Second, patients with AD, but not patients with MCI or older adults, appeared to retain more memory for personal versus factual information. Third, patients with AD and older adults did not differ in the intensity of their reported emotional responses to the attacks, whereas patients with MCI reported relatively less intense emotional responses. Last, distortions of memory for personal information were frequent for all participants but were more common in patients with AD. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

基于视觉物联网的暴恐人员快速定位追踪仿真

在大范围暴恐人员定位过程中,暴恐份子带有逃逸、遮挡、伪装的过程,给视觉定位过程带来定位区域难以划分的问题,传统混沌粒子群的暴恐人员定位方法,需要对定位区域有明确的限制,由于控制区域无法准确划分,对暴恐人员无法获取准确的区域.导致定位结果失真.提出基于视觉物联网的暴恐人员快速定位追踪方法,分析了视觉物联网的暴恐人员监控平台的图像,通过计算机视觉技术采集所有可能为暴恐人员的图像信息,根据暴恐人员身体特征同其所在类均值间的误差,采用迭代运算使误差平方和最小化,实现全部循环即获取全部暴恐人员区域准确信息,依据图像向量分辨出不同暴恐人员的面部特征,使用学习集与模糊均值聚类方法识别暴恐人员的面部特征,完成对暴恐人员定位追踪.实验表明,所提方法可准确获取暴恐人员的位置信息,具有较高的定位精度.     

公共安全与核监测

针对＂中华人民共和国突发事件应对法＂界定的四类突发事件中社会安全事件,从核和辐射恐怖突发事件公共安全角度阐述了核和辐射恐怖主义四类袭击手段的潜在威胁是在国际范围内对公共安全最具挑战性的威胁之一。按照＂应对法＂提出了＂预防为主,预防与应急响应相结合＂原则以及相应的行动谱。核和辐射恐怖突发事件的防范与应急响应的核心技术是核监测。全面系统地论述了核监测技术,包括：开展核和辐射恐怖事件防范与响应的核监测战略研究;为防范核和辐射恐怖事件,对核材料与其他放射性物质以及IND,RDD,RED的探测、报警、定位与识别,建立全国性辐射监测网（体系）;核和辐射恐怖事件发生后果管理中应急响应的辐射监测特殊要求与相应技术。     

What predicts psychological resilience after disaster? The role of demographics, resources, and life stress.

A growing body of evidence suggests that most adults exposed to potentially traumatic events are resilient. However, research on the factors that may promote or deter adult resilience has been limited. This study examined patterns of association between resilience and various sociocontextual factors. The authors used data from a random-digit-dial phone survey (N = 2,752) conducted in the New York City area after the September 11, 2001, terrorist attack. Resilience was defined as having 1 or 0 posttraumatic stress disorder symptoms and as being associated with low levels of depression and substance use. Multivariate analyses indicated that the prevalence of resilience was uniquely predicted by participant gender, age, race/ethnicity, education, level of trauma exposure, income change, social support, frequency of chronic disease, and recent and past life stressors. Implications for future research and intervention are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Young children in the aftermath of the World Trade Center attacks.

The attacks of September 11, 2001, on the World Trade Center were unprecedented acts of terrorism on U.S. soil. The disaster provides an opportunity to understand the responses of young children to a traumatic event of this proportion. This retrospective study took place within a year of the attacks and examined the relationship of levels of exposure to the World Trade Center disaster and family level predictors to trauma symptoms in a highly exposed sample of 180 young children in New York City. Data were collected through interviews with parents of children five years or younger at the time of the attacks. Primary variables included direct exposure and post 9/11 child and parent functioning, including trauma symptoms. Child trauma symptoms were related to direct exposure to the disaster, previous trauma, negative changes in parenting, and increased couple tension. Findings support the conceptualization that children's responses to traumatic events must be addressed within the caregiving context of family relationships. Clinical and preventive intervention for young children should be aimed at multiple levels of the social ecology. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Acute stress disorder in diplomats, military, and civilian Americans living abroad following the September 11 terrorist attacks on America.

Can expatriates witnessing the attack of their country from afar develop acute and posttraumatic stress reactions? In Brussels 50 expatriate Americans were surveyed in the 10 weeks following September 11. Of the sample, 10% (n=5) showed acute stress disorder in the 1st week, and 4% (n=2) persisted with traumatic stress indications in the following weeks. All participants showed symptoms of distress, including derealization, reexperiencing the event, avoidance, heightened arousal, trouble working, and assault on world assumptions. For most, symptoms diminished over time. Increased psychological readiness in terms of assessment, prevention, and treatment methods is called for in response to mass terrorism.

基于特征选择和超参数优化的恐怖袭击组织预测方法

针对恐怖袭击事件难以找到恐怖袭击组织以及恐怖袭击事件数据的样本不平衡问题,提出了一种基于特征选择和超参数优化的恐怖袭击组织预测方法。首先,利用随机森林（RF）在处理不平衡数据上的优势,通过RF迭代来进行后向特征选择;然后,利用决策树（DT）、RF、Bagging和XGBoost这四种主流分类器对恐怖袭击组织进行分类预测,并利用贝叶斯优化方法对这些分类器进行超参数优化;最后,利用全球恐怖主义数据库（GTD）评价了这些分类器在多数类样本和少数类样本上的分类预测性能。实验结果表明：所提方法提高了对恐怖袭击组织的分类预测性能,其中使用RF和Bagging时的分类预测性能最佳,准确率分别达到0.823 9和0.831 6,特别是在少数类样本上的分类预测性能有明显提高。
