基于失效模式分析的脱硫罐全面检验

基于脱硫罐结构以及脱硫工艺分析,研究脱硫罐的失效模式,应力集中是其产生裂纹导致疲劳失效的主要原因。在此基础上采用宏观检查、超声波测厚、表面磁粉检测等检测方法对脱硫罐进行全面检测,安全评定脱硫罐的失效现状,同时提出了此类压力容器安全运行及检验的改进建议,提高安全监管的科学性和有效性,避免事故的发生,确保设备安全、长周期运行。     

铸铁烘缸主螺栓的设计计算

从压力容器设计基本理论出发,遵照新的《固定式压力容器安全技术监察规程》及有关规定,对铸铁烘缸用主螺栓进行了受力分析,给出了详细的计算方法,除按强度计算外,还应作疲劳强度校核,通过受力分析,给出了全新的强度计算公式,不同于其它基于连接螺栓计算方法,由于提出残余预紧力估算,该项理论分析计算达到较高精度,由此为铸铁烘缸的设计及行业标准的修订奠定了基础。     

Interval estimation of the stress–strength reliability in the two-parameter exponential distribution based on records

We consider interval estimation of the stress–strength reliability in the two-parameter exponential distribution based on records. We constructed Bayesian intervals, Bootstrap intervals and intervals using the generalized pivot variable. A simulation study is conducted to investigate and compare the performance of the intervals in terms of their coverage probability and expected length. An example is given.     

Interval estimators for reliability: the bivariate normal case

This paper proposes procedures to provide confidence intervals (CIs) for reliability in stress–strength models, considering the particular case of a bivariate normal set-up. The suggested CIs are obtained by employing either asymptotic variances of maximum-likelihood estimators or a bootstrap procedure. The coverage and the accuracy of these intervals are empirically checked through a simulation study and compared with those of another proposal in the literature. An application to real data is provided.     

Macro stress testing and resilience assessment of Indian banking

This study conducts policy-based macro stress testing of the Indian banking sector and also assesses its resilience towards compliance with BASEL norms with the aid of an empirical macro-financial model. It uses scenario analysis and quantitative techniques to capture the impact of macroeconomic stress on the stability of the Indian banks by evaluating financial soundness indicators (credit quality, quantity and quality of capital adequacy). The scenarios are generated through policy-based shocks vis-à-vis other external shocks. The results from the estimation of the model indicate a cointegrating relationship between credit quality and key macroeconomic variables including output growth rate, interest rate, money growth rate and exchange rate. The results of the scenario analysis reveal that the Indian banking sector remains largely sound in terms of total regulatory capital adequacy ratio as per current BASEL II and even BASEL III requirement. The results also show that expansionary monetary policy impacts credit quality and capital adequacy in a positive and significant manner via its effect on the economy’s growth rate.     

Subjective experiences of older adults in poverty in urban China and the role of social policy

This study establishes an evidence base regarding the experiences of older adults living in poverty in Beijing. Given the factors that shape the lives of low-income older adults, the findings are relevant for many middle- and low-income countries. Based on a series of in-depth interviews conducted with government officials and low-income older adults in Beijing, the study finds that poverty manifests as cumulative stress arising from four sources: financial strain, poor health, care burden and poverty-related shame. This stress is attributable to the co-existence of individual and structural factors that reflect the framing of anti-poverty policies in China.     

组织中的工作压力来源及其管理

大量的研究证明,工作压力对组织有着举足轻重的影响。工作压力不仅影响组织中个体的身心健康,更是影响组织环境、组织绩效的根源。它涣散组织的内聚力,增加人员的流动性,提高人力资源成本。组织可以通过消除压力的来源、改变员工的不良认知,提供社会支持等策略降低或消除工作压力对组织的负面影响,使组织健康发展。

A Brief Treatment with a Posttraumatic Stress Disordered Patient—A Self Psychological Perspective

Treatment of posttraumatic stress disordered patients has focused predominantly on symptom removal. The assumption is that once the symptoms of stress are alleviated, the individual can return to a previous level of functioning. This focus overlooks the psychological importance of the unique and permanent effects that traumatic stress can have on the way individuals experience themselves and the world. This brief paper contributes to an understanding of the importance of psychoanalytic treatment in helping a patient understand her longstanding need for preoccupation with thoughts of destruction and how this need prolonged her thinking about the 9/11 tragedy. As her understanding proceeded, the patient’s preoccupation with the suicide attacks diminished as did her negative preoccupations in general.     

Stress, Trauma, and Coping Strategies: Cross-Cultural Variations

This article examines three major issues. First, it considers the nature of trauma, its cognitive and emotional appraisal, and the cultural variations in its appraisal. In this context, it also distinguishes between universal traumas and culture-specific traumas with pertinent examples. In addition, the conceptual, epistemological, and methodological problems of investigating trauma across cultures are highlighted. Second, the article critically examines the controversies surrounding the nature, theoretical formulations, and methodologies currently adopted in stress research both in Western and non-Western cultures, with special emphasis being placed on the situation prevailing in Indian stress research. Third, it focuses on therapeutic issues and highlights some of the culture-specific healing techniques used by some people in Indian cultures to cope with stress and trauma. Finally, it suggests ways by which one might achieve a rapprochement between Western approaches and non-Western approaches to the study of stress and trauma.
