We used statistical data on the STAs occurring in Japan from 1987 to 2018, which included the frequency, types, causes, and consequences of the STAs, along with additional derailment, collision, and casualty data. We investigated the historical trend of the STAs using various probabilistic mathematical modeling approaches, such as Markov models, logit regression models, Bayesian approaches, and artificial-intelligence techniques. We showed that the number of casualties in STAs involving collisions was significantly larger than that for accidents not involving collisions. Thus, the statistical analysis indicated that preventing train collisions is the most important and necessary measure for reducing damage to passengers. Additionally, we proposed several countermeasures for ensuring the safety of passengers in Japan, e.g., install automatic train stops for all railway companies of Private Railway and terminate the use of ground-level crossings without gates. We evaluated the effectiveness of these countermeasures from various viewpoints.</p></div>","PeriodicalId":101193,"journal":{"name":"Sustainability Analytics and Modeling","volume":"2 ","pages":"Article 100005"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667259622000030/pdfft?md5=be636475407a8e592c7bcf41c55c0d08&pid=1-s2.0-S2667259622000030-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72246664","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Control variables are government size, trade, and population density. Based on the results, political stability and lack of violence have positive effect on Adjusted Net Saving (ANS) ratio, while government size affects ANS negatively. In addition, trade impacts on weak sustainability in the current sample, rejecting pollution haven hypothesis. The effect of population density on ANS is positive. This effect is unexpected which requires further studies. According to our findings, Asian countries should follow stabilizing policies, especially in political races and campaigns.</p></div>","PeriodicalId":101193,"journal":{"name":"Sustainability Analytics and Modeling","volume":"2 ","pages":"Article 100007"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667259622000054/pdfft?md5=2bd8db84be782b1cd34f7f4033728969&pid=1-s2.0-S2667259622000054-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81869629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sustainability and healthcare are intricately related since the quality of our environment affects public health. Based on the acknowledged sustainability practices in healthcare, a compendious theoretical model for sustainability in healthcare has been developed, grounded in appropriate theories. The model encompasses twenty-seven sustainability practices under its triple bottom line (TBL), which have been subsequently reorganized and arranged for analysis into twelve sustainability measures on recommendation from a set of experts. This study investigates the measures of sustainability in Indian healthcare based on an integrated methodology of Analytic Hierarchy Process (AHP) and Interpretive Structural Modelling (ISM). Expert elicitation was employed for establishing the importance, as well as the interrelationships among, the measures. Consequently, a strategic theoretical framework for sustainable healthcare is proposed on the basis of the findings of the ISM method and <em>Matrice d'Impacts Croises Multiplication Appliquee a un Classement</em> (MICMAC) analysis. This work has studied the key measures that emerged for policy, practice, and research. The results suggest that research &amp; innovations and indigenous production are significant drivers of sustainable healthcare. In addition, the mediating measures viz. circular practices, waste reduction and management, integrated facilities design, sustainable procurement, employee satisfaction, and green growth may offer guidance and provide a strong direction to healthcare managers and practitioners in achieving their sustainability goals.</p></div>","PeriodicalId":101193,"journal":{"name":"Sustainability Analytics and Modeling","volume":"1 ","pages":"Article 100001"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667259621000011/pdfft?md5=5e043f8c9fd313b9f874f79eeb2c7ad3&pid=1-s2.0-S2667259621000011-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85967566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firms in such industries need to make frequent design changes to incorporate innovations, and the effort to keep up with the rate of technological change often leaves little room for the consideration of product reuse. In this paper, we study the design for reusability and product reuse decisions in the presence of both a known rate of incremental innovations and a stochastic rate of radical innovations over time. We formulate this problem as a Markov Decision Process. Our steady-state results confirm the conventional wisdom that a higher probability of radical innovations would lead to reductions in the firm's investments in reusability as well as the amount of reuse the firm ends up doing. Interestingly, the design for reusability decreases much more slowly than the actual reuse. We identify some specific scenarios, however, where there is no tradeoff between the possibility of radical innovations and the firms reusability and reuse decisions. Based on over 425,000 problem instances generated over the entire range of model parameters, we also provide insights into the negative impact of radical innovations on firm profits, but show that the environmental impact of increased radical innovation is not necessarily negative. Our results also have several implications for policy makers seeking to encourage reuse.","PeriodicalId":101193,"journal":{"name":"Sustainability Analytics and Modeling","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77985311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
