The Relationship Between Child Sexual Abuse and Alexithymic Symptoms in a Population of Recovering Adult Substance Abusers

ABSTRACT

Recovering substance abusers with a history of childhood sexual abuse (n = 69) or no history of childhood sexual abuse (n = 68) completed the Toronto Alexithymia Scale (TAS) and a background survey assessing demographic data and (In the case of sexually abused respondents) parameters of the childhood abuse experienced. The sexually abused group scored significantly higher than the non-abused group on the TAS. Within the abused group, measured alexithymic symptomatology was found to be related positively to the duration of the abuse. Alexithymia was significantly higher when the sexual abuse first occurred after the victim had reached the age of 12, when a perpetrator of the sexual abuse was a father or stepfather, and when the abuse involved oral, vaginal, and/or anal penetration. Results were interpreted as indicating that the development of alexithymic symptoms may represent another defense victims may employ to insulate themselves from painful affect, along with dissociative symptoms and substance abuse, which have been shown previously to characterize adult survivors of child sexual abuse.     

On Calculations Involving the Maximum Cell Frequency

We describe a method of computing the cumulative distribution function of the maximum and minimum cell frequencies in sampling distributions commonly encountered in the analysis of categorical data.The procedure is efficient for exact or approximate calculation in both homogeneous and non-homogeneous cases, is non-recursive, and does not require Dirichlet integrals.Some related statistical problems are also discussed.     

Assessing Engineering Resilience for Systems with Multiple Performance Measures

Recently, efforts to model and assess a system's resilience to disruptions due to environmental and adversarial threats have increased substantially. Researchers have investigated resilience in many disciplines, including sociology, psychology, computer networks, and engineering systems, to name a few. When assessing engineering system resilience, the resilience assessment typically considers a single performance measure, a disruption, a loss of performance, the time required to recover, or a combination of these elements. We define and use a resilient engineered system definition that separates system resilience into platform and mission resilience. Most complex systems have multiple performance measures; this research proposes using multiple objective decision analysis to assess system resilience for systems with multiple performance measures using two distinct methods. The first method quantifies platform resilience and includes resilience and other “ilities” directly in the value hierarchy, while the second method quantifies mission resilience and uses the “ilities” in the calculation of the expected mission performance for every performance measure in the value hierarchy. We illustrate the mission resilience method using a transportation systems‐of‐systems network with varying levels of resilience due to the level of connectivity and autonomy of the vehicles and platform resilience by using a notional military example. Our analysis found that it is necessary to quantify performance in context with specific mission(s) and scenario(s) under specific threat(s) and then use modeling and simulation to help determine the resilience of a system for a given set of conditions. The example demonstrates how incorporating system mission resilience can improve performance for some performance measures while negatively affecting others.

"职业教育"概念与功能的历史观

职业伴随着劳动分工而产生,职业教育则是近代大机器工业的产物。在不同的历史时期,人们从不同的角度观察,并对职业教育产生了不同的认识,以不同的名称表述,赋予不同的功能。"五四"时期职业教育的多元共生,反映出人们对职业教育概念、功能的不同认识,这也是中国近代职业教育向现代职业教育跨越的重要标志。     

Marginal Means/Rates Models for Multiple Type Recurrent Event Data

Recurrent events are frequently observed in biomedical studies, and often more than one type of event is of interest. Follow-up time may be censored due to loss to follow-up or administrative censoring. We propose a class of semi-parametric marginal means/rates models, with a general relative risk form, for assessing the effect of covariates on the censored event processes of interest. We formulate estimating equations for the model parameters, and examine asymptotic properties of the parameter estimators. Finite sample properties of the regression coefficients are examined through simulations. The proposed methods are applied to a retrospective cohort study of risk factors for preschool asthma.     

茅盾小说与"红楼"情结

“红楼”情结是茅盾经久的“图像仓库”的土壤。但这种情结不是板块式地嵌入的 ,而是经由转化、挪移、重组化合而生成的。这种历史的承传 ,可以是正面的 ,也可以是负面的。同时 ,这种对民族文化的吸取是在与中外艺术的多元交糅的关系中 ,融通建构的。     

克里斯特瓦的理论背景与诗学思想

克里斯特瓦是当代法国著名的文学理论家和批评家,她的诗学思想融合了多种学科的知识,且复杂多变。她既受马克思、阿尔都塞、黑格尔、索绪尔、巴赫金、弗洛伊德、拉康、德里达、巴特等人的影响,又修正、发展或批判他们的理论。她创建的解析符号学和互文性理论促进了后结构主义理论的发展;她对文本的对话论、复调结构以及诗性话语的探讨,丰富和发展了巴赫金的文学理论;她关于女性与女性特质的界定,使她的女性主义诗学独树一帜;她对欲望、母性、爱情、卑贱等主题的探讨,修正了传统的精神分析方法。
