evaluating the Risk of operational safety for dangerous goods in airfreights a revised Risk Matrix based on fuzzy ahp
Transportation Research Part D-transport and Environment, 2016Co-Authors: Showhui S Huang, Wenjui TsengAbstract:Abstract The purpose of this study is to assess the Risk of operational safety for dangerous goods in airfreights. Based on the relevant literature, the Risk factors (RFs) of operational safety were first investigated. A revised Risk Matrix based on fuzzy AHP (Analytic Hierarchy Process) was then proposed to assess the Risks of those RFs’ in operational safety. Finally, to validate the model, the airfreight operations of dangerous goods in Taiwan were empirically investigated. The results indicate the RFs with higher Risk in shipper’s operations are inaccurate declaration, insufficient knowledge and insufficient packaging. For the results, theoretical and managerial implications are further discussed. The results can provide practical information for airfreight operators to improve the performance of safety management. Further, the revised Risk Matrix can provide methodological reference for Risk assessment research.

Is the Risk Matrix 2000 applicable to intellectually disabled sex offenders
Aggression and Violent Behavior, 2015Co-Authors: Jennifer Pryboda, Ruth J. Tully, Kevin D. BrowneAbstract:Abstract Background Sex offender Risk assessment is complex, especially when this concerns intellectually disabled sex offenders (IDSOs). This subgroup of sex offenders require specific attention in relation to Risk assessment, yet tools designed for non-IDSOs continue to be applied to them. Method This review examines the Risk Matrix 2000, a static Risk assessment tool that is designed to assess Risk of sexual and violent recidivism. Its validity, reliability and practical utility for sex offenders with intellectual disabilities are explored. Results Appraisal of this tool indicates that although empirical support exists for its use with sex offenders without intellectual disability, the Risk Matrix 2000 is not established as reliable or valid for use with IDSOs. Although less extensively empirically examined than the Risk Matrix 2000, the ARMIDILO-S, which incorporates protective factors as well as Risk factors, shows superior predictive validity to the Risk Matrix 2000 with IDSOs and its use may therefore be more ethically defensible. Specific testing of actuarial (and other types) of tools is required on IDSOs. Conclusions Further empirical support is needed to support the use of the Risk Matrix 2000 with IDSOs, and other Risk assessment tools that are designed specifically for this subgroup of sex offenders may be more appropriate to use. The Risk Matrix 2000 and its resulting Risk groups should not be relied upon for IDSOs and its continued use on this subgroup is questionable.

appraising the Risk Matrix 2000 static sex offender Risk assessment tool
International Journal of Offender Therapy and Comparative Criminology, 2015Co-Authors: Ruth J. Tully, Kevin D. BrowneAbstract:This critical appraisal explores the reliability and validity of the Risk Matrix 2000 static sex offender Risk assessment tool that is widely used in the United Kingdom. The Risk Matrix 2000 has to some extent been empirically validated for use with adult male sex offenders; however, this review highlights that further research into the validity of this static tool with sex offender subgroups or types is necessary in order to improve practical utility. The Risk Matrix 2000 relies on static Risk predictors, thus it is limited in scope. This article argues that the addition of dynamic items that have been shown to be predictive of sexual recidivism would further enhance the tool. The paper argues that adding dynamic Risk items would fit better with a rehabilitative approach to sex offender Risk management and assessment. This would also provide a means by which to effectively plan sex offender treatment and evaluate individual offenders’ progress in treatment; however, difficulties remain in identifying and...

cross validation of the Risk Matrix 2000 sexual and violent scales
Journal of Interpersonal Violence, 2006Co-Authors: Leam A Craig, Anthony R Beech, Kevin D. BrowneAbstract:The predictive accuracy of the newly developed actuarial Risk measures Risk Matrix 2000 Sexual/Violence (RMS, RMV) were cross validated and compared with two Risk assessment measures (SVR-20 and Static-99) in a sample of sexual (n= 85) and nonsex violent (n= 46) offenders. The sexual offense reconviction rate for the sex offender group was 18% at 10 years follow-up, compared with 2% for the violent offenders. Survival analyses revealed the violent offenders were reconvicted at twice the rate compared to sexual offenders. The RMV significantly predicted violent recidivism in the sex and combined sex/violent offender groups. Although the RMS obtained marginal accuracy in predicting sexual reconviction in the sex offender group, none of the scales significantly predicted sexual reconviction. An item analysis revealed four factors not included in the Risk scales that were significantly correlated with sexual and violent reconviction. Combining these factors with Static-99, RMV, and RMS increased the accuracy ...

fishbone diagram and Risk Matrix analysis method and its application in safety assessment of natural gas spherical tank
Journal of Cleaner Production, 2018Co-Authors: Chao Wu, Lixiang DuanAbstract:Abstract Gas spherical tank leak can cause a serious fire and explosion accident, resulting in huge economic losses and posing a huge threat to social security. By combining improved fishbone diagram and Risk Matrix model, we studied a comprehensive Risk assessment method. Quantitatively calculate the probability of occurrence: Firstly, we established a fishbone diagram model to analyze the causes of all spherical tank leakage events. Then the experts would rank causes of the incident in language description, next we assigned weights to these experts’ competencies by Entropy–Analytic Hierarchy Process, so we could turn the language description into fuzzy probability value using fuzzy mathematic theory. Finally, we calculated the occurrence probability of the Resultant events by Fault tree model. Quantitatively calculate the probability of consequence: From casualties, economic losses and environmental damage to consider the total loss caused by the leak accident, and combining with the probability of occurrence to calculate the consequences losses quantitatively. After modifying classical Risk Matrix, we analyzed the spherical tank leak level with considering occurrence probability and sequence severity. At the same time, we proposed specific measures for reason accidents which have greater occurrence probability to eliminate or reduce the Risk of consequences.

a Risk Matrix analysis method based on potential Risk influence a case study on cryogenic liquid hydrogen filling system
Process Safety and Environmental Protection, 2016Co-Authors: Yongsheng Duan, Jiguang Zhao, Jingpeng ChenAbstract:Abstract A Risk Matrix analysis framework is proposed for Risk assessment and prioritization based on potential Risk influence (PRI). First, a new principle for Risk level assignment considers the potential impacts of Risk, including controllability, criticality, manageability and uncertainty, is established. Next, the impacts of potential Risk are divided into two Risk influence factors in Risk Matrix: probability and consequence influence factor. A fuzzy probability method is used to calculate the failure probability of basic events when appropriate reliability data is unavailable. To take the dependence of basic events into account, Bayesian belief network models established to calculate the likelihood of failure. Finally, to demonstrate the validity of the proposed method, a Risk assessment and a Risk ranking process are performed for a cryogenic liquid hydrogen filling system (CLHFS). The results of the case study confirmed that the proposed methodology successfully manages Risk level inconsistency, and is altogether a feasible and reasonable tool for Risk management.
