Technical risk involved in long-term operation of steam turbines

The scope of the paper is the assessment of the technical risk involved in long-term operation of power units. Detailed analyses have been conducted for steam turbine components. The sources and consequences of risk have been identified and the probability of turbine components failure calculated. The quantitative assessment of the risk has been made and possibilities of its reduction discussed.     

Distinctive Features of Minimization of a Risk Functional in Mass Data Sets

A statistical learning model is considered within the framework of the theory of uniform convergence of frequencies of errors in the case where the convergence is violated as a result of increasing the informativeness of training examples. Drawbacks of nonconstructive refinements of Vapnik-Chervonenkis estimates based on an assumption on the distribution law of violations are shown. A new approach to obtaining constructive estimates for mass data sets is proposed.     

Critical incidents and chronic stressors at work: Their impact on forensic doctors.

Workers in medium- or high-risk professions are often confronted with critical incidents at the workplace. The impact of these acute stressors may be serious and enduring. Many workers also experience chronic job stressors, such as work overload or role conflicts. This study examined the frequently neglected relationship of acute and chronic stressors with self-reported health symptoms, such as posttraumatic responses, fatigue, and burnout. This association was investigated in a sample of forensic doctors in the Netherlands (N = 84). It was found that the more traumatic events the respondents experienced, the more problems they reported in coping with the traumatic events. Chronic job stressors were associated with posttraumatic responses (intrusions and avoidances) and with burnout and fatigue. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Risk evaluations for the courts: Is service quality a function of specialization?

Psychologists are often asked to testify in court. However, concerns have been expressed in both the legal and psychological literatures about the quality of these services. This article presents survey results comparing the practice patterns of generally licensed psychologists with those of specialist forensic diplomates in providing risk evaluations. Results suggest that general clinicians frequently perform these evaluations, but forensic diplomates use more modern risk instruments, are more aware of the scientific literature, and provide the court with more information about the scientific basis of their testimony. The implication of these results for legal professionals, psychologist training, and practice are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Verifiable Distributed Oblivious Transfer and Mobile Agent Security

The mobile agent is a fundamental building block of the mobile computing paradigm. In mobile agent security, oblivious transfer (OT) from a trusted party can be used to protect the agent’s privacy and the hosts’ privacy. In this paper, we introduce a new cryptographic primitive called Verifiable Distributed Oblivious Transfer (VDOT), which allows us to replace a single trusted party with a group of threshold trusted servers. The design of VDOT uses a novel technique called consistency verification of encrypted secret shares. VDOT protects the privacy of both the sender and the receiver against malicious attacks of the servers. We also show the design of a system to apply VDOT to protect the privacy of mobile agents. Our design partitions an agent into the general portion and the security-sensitive portion. We also implement the key components of our system. As far as we know, this is the first effort to implement a system that protects the privacy of mobile agents. Our preliminary evaluation shows that protecting mobile agents not only is possible, but also can be implemented efficiently.

对油田企业建设和执行内部控制体系的思考

内部控制是一个由企业董事会、管理层和其他员工实施的,为实现企业经营的效果和效率目标、财务报告的可靠性目标和舍规性目标提供合理保证的过程。有效地建设以及有力地执行内控制度,对石油企业发展过程中有效地避免风险的发生起着非常重要的作用。但是,由于种种原因,油田企业目前的内部控制体系还不成熟,还存在着一些建设上的不足和执行上的不力。同时,企业员工普遍对内部控制还存在着一些认识误区,这就要求我们必须努力学习内控知识,加强内控知识培训,充分调动企业全体员工建设和雏护内部控制体系的积极性和自觉性,使得内控可以真正发挥其防范风险的作用。     

卡伦水库洪水风险调度效益浅析

本文主要从选择卡伦水库实行洪水风险调度的依据、水库洪水控制标准、调度原则及效益等方面论述卡伦水库实行洪水风险调度的重大意义。特别强调在水库洪水调度过程中适度承担风险,必须确保工程安全运行、科学调度,加强管理,依法防洪,合理蓄水,要正确把握水库安全度汛与水资源合理利用的关系,正确处理防洪与兴利的关系,正确处理风险与效益的关系,充分发挥水库的综合效益。适度承担风险进行水库洪水调度,既充分利用雨洪资源,又尽最大可能变水害为水利,实现雨洪资源化,达到人、水与自然和谐共处,促进经济社会协调发展。
