Improving Risk Management: From Lame Excuses to Principled Practice

The three classic pillars of risk analysis are risk assessment (how big is the risk and how sure can we be?), risk management (what shall we do about it?), and risk communication (what shall we say about it, to whom, when, and how?). We propose two complements as important parts of these three bases: risk attribution (who or what addressable conditions actually caused an accident or loss?) and learning from experience about risk reduction (what works, and how well?). Failures in complex systems usually evoke blame, often with insufficient attention to root causes of failure, including some aspects of the situation, design decisions, or social norms and culture. Focusing on blame, however, can inhibit effective learning, instead eliciting excuses to deflect attention and perceived culpability. Productive understanding of what went wrong, and how to do better, thus requires moving past recrimination and excuses. This article identifies common blame‐shifting “lame excuses” for poor risk management. These generally contribute little to effective improvements and may leave real risks and preventable causes unaddressed. We propose principles from risk and decision sciences and organizational design to improve results. These start with organizational leadership. More specifically, they include: deliberate testing and learning—especially from near‐misses and accident precursors; careful causal analysis of accidents; risk quantification; candid expression of uncertainties about costs and benefits of risk‐reduction options; optimization of tradeoffs between gathering additional information and immediate action; promotion of safety culture; and mindful allocation of people, responsibilities, and resources to reduce risks. We propose that these principles provide sound foundations for improving successful risk management.     

Transition probabilities and ARL performance of Six Sigma zone control charts

In this article, Six Sigma zone control charts (SSZCCs) are proposed for world class organizations. The transition probabilities are obtained using the Markov chain approach. The Average Run Length (ARL) values are then presented. The ARL performance of the proposed SSZCCs and the standard Six Sigma control chart (SSCC) without zones or run rules is studied. The ARL performance of these charts is then compared with those of the other standard zone control charts (ZCCs), the modified ZCC and the traditional Shewhart control chart (SCC) with common run rules. As expected, it is shown that the proposed SSZCC outperforms the standard SSCC without zones or run rules for process shifts of any magnitude. When compared to the other standard ZCCs and the Shewhart chart with common run rules, it is observed that the proposed SSZCCs have much higher false alarm rates for smaller shifts and hence they prevent unwanted process disturbances. The application of the proposed SSZCC is illustrated using a real time example.

川西藏区藏族中小学校长心理控制源的调查分析

川西藏区地处四川省西部,其特殊的历史地理环境使得这一区域成为藏、汉、羌、彝等民族的聚居地,成为多元文化相互影响、相互碰撞的交汇之地。生活在这里的个体,特别是承担着振兴民族教育事业的各位藏族中小学校长们,在面对相对艰苦的自然环境、相对贫乏的教育资源、特别是面对多种文化交互影响的过程中,在个体心理控制源上表现出怎样的特征呢?作者采用罗特(Rotter.J.B)编制的《内在—外在心理控制源量表》对126名来自四川省甘孜、阿坝和凉山地区的藏族中小学校长进行了测试。结果表明:1、该地区藏族中小学校长的心理控制源在总体上倾向于内控性;2、其内控性在性别、年龄、学校所在地这三个因素上差异不显著;3、被测试的藏族中小学校长们普遍具有较强的社会适应能力。

藏汉中学生心理健康水平比较研究综述

心理健康教育是教育者应用心理学、教育学、社会学乃至精神医学等多种学科的理论和技术,通过多种途径与方法,培养学生良好的心理素质,提高心理机能,充分发挥其心理潜能,从而促进学生整体素质全面提高和发展的教育。藏族学生在学校学习的过程实际上是两种或两种以上文化之间交流并融合的过程,所有影响交流的因素都有可能对藏族学生的心理发展产生影响。教育落后是制约西部地区经济发展的根本原因。因此,研究西部少数民族学生的心理与教育,对于加快发展西部教育事业具有强烈的现实意义。
