The paper contains the analysis of the data on major industrial accidents and occupational injuries at the coal mine industry enterprises of Russia in order to reveal statistically significant correlations between the indicators impacting the accident rate and the employees’ death risk level. As the risk criteria, the values of the methane-air resultant mixtures (MARM) explosions frequency and the frequency of the staff exposure at MARM explosions in the mines (observed levels of personal risks) are taken. The Kolmogorov–Smirnov test and Kruskal–Wallis test are used to analyze the categorized data samplings over the period from 2005 to 2016. The authors have defined the influence of relative gas content and hazard of layers regarding spontaneous combustion on the MARM explosions frequency. The regression models that take into consideration the impact of hazardous factors on the risk indicators have been received. The results of the performed coal mines ranging in Russia have been presented according to the level of individual risk, caused by MARM explosions; the received results have been compared with the acceptable tolerable risk level. The relevance of applying the research findings has been shown at the implementation of the dynamic model of the risk-based approach for ensuring coal mines safe exploitation.

Based on two dimensions of system risk, this paper studies the changes in the future inflation risk level, and uses the out-of-sample quantile R2  to further evaluate the predictive accuracy of different systemic risk indicators on inflation risk. Firstly, we compute two systemic risk indicators, MES and volatility, with data of Chinese financial institutions. And then we explore the amplification effect of these indicators on future inflation risk, under the framework of quantile regression. We find that systematic risk indicators have a strong predictive ability for the inflation level at various quantiles. MES indicator that reflects individual risk can better predict future deflation risk, while volatility index has a stronger ability to predict inflation risk. We also find that systemic risk indicators of different dimensions have different effects on inflation risk and deflation risk. In general, the MES index, which captures the individual risk of the organization, have a greater impact on the future inflation risk. While indicator that measures volatility in financial markets has more influence on the extreme lower tail of inflation rates. Finally, we predict the distribution of inflation in China from March 2020 to June 2021, and visually show the distribution trend of future inflation with forecast fan charts.

The aim of this paper is revelation of risks caused by inhalation of toxic elements, containing in emissions of boilers using different types of fuels (coal, oil, gas, woods), and the pollutants priority identification. The carcinogenic and non-carcinogenic risks factors have been calculated through calculated data on trace elements concentrations in the air, based on established experimentally their content in the snow cover’s solid phase. According to the total value of the inhalation impact’s danger factor the studied territories can be ranked in the following range of boilers: coal > woods >gas ≥ oil ones. The impact of these activities can be appraised as permissible and acceptable. Contributions of heavy metals into risk characteristics have been ranked. Elements Mn, Cu, Ba, Al make the major contribution to the hazard coefficient and are among the elements-indicators for ash emissions of coal boilers. For all elements with carcinogenic properties (Cr (VI), Cd, As, Be, Ni, Co, Pb) the values of individual carcinogenic risk are below 10–5 for environs of all considered boilers. Such values correspond to the negligible risk level. From a practical standpoint, the heavy metals’ emissions differentiation both by nature and content, when using different types of fuel, affects the health risk indicators and can be informative when choosing a fuel for boilers of individual housing construction.

Abstract Relationship research has suggested that health among spouses is interdependent and should be considered jointly. Using data from the 2008/2010 and 2016/2018 waves of the Health and Retirement Study (3858 qualified couples; age=67.0±9.6), we investigated the joint influence of married partners’ individual and shared cumulative biological risk on future health outcomes. Two risk indicators were constructed to indicate biological health in different domains. Individual grip strength, walk speed, lung function, and cystatin-C were biomarkers selected to construct frailty risk whereas blood pressure, pulse, waist circumference, C-reactive protein, glycohemoglobin, high-density lipoprotein cholesterol, and total cholesterol were biomarkers used to construct cardiometabolic risk. Shared risk was calculated as the number of risks the partners shared. We employed multilevel Poisson regression models to nest partners within couples and examine the effects of individual and shared cumulative risks on future functional limitations. Heckman correction was performed to correct potential selection bias. Our unadjusted models showed individual (frailty: b=0.22, p<.001; cardiometabolic: b=0.10, p<.001) and shared (frailty: b=0.17, p<.001; cardiometabolic: b=0.08, p<.01) risks are associated with greater future functional limitations. Further, shared cardiometabolic risk moderated the effect of individual risk (b=-0.01, p<.05). In the adjusted models, the direct associations between shared risks and future functional limitations were explained by indicators of partner selection and shared experiences. In the fully adjusted model, the cross-level interaction for frailty risk became statistically significant. The unique set of dynamics shown in our study offered new insights into understanding how couples influence one another in the context of multisystem biological health.

This study focuses on examining the impact of three components of materialism on green purchase intention for urban consumers in Vietnam, an emerging economy. An extended Theory of Planned Behavior (TPB) is applied as the conceptual framework for this study. The hypotheses are empirically tested using survey data obtained from consumers in Hanoi, the capital of Vietnam. The regression results show support for most of our hypotheses. The findings indicate that two out of three facets of materialism are significant predictors of green purchase intention. Specifically, success is found to be negatively related to purchase intention, while happiness is related positively to the intention. All three antecedents in the TPB model, including attitude towards green purchase, subjective norm, and perceived behavioral control are also found to have positive impacts on purchase intention. The research findings are discussed and implications for managers and policy makers are provided.

Introduction. Due to the impact of adverse working conditions and climate, workers in coal-mining enterprises in the Arctic are at increased risk of occupational diseases (OD).The aim of the study was to study the working conditions, causes, structure and prevalence of occupational diseases in miners of coal mines in the Arctic.Materials and methods. Th e data of social and hygienic monitoring “Working conditions and occupational morbidity” of the population of Vorkuta and Chukotka Autonomous District in 2007–2017 are studied.Results. It was established that in 2007–2017 years, 2,296 ODs were diagnosed for the first time in 1851 coal mines, mainly in the drifters, clearing face miners, repairmen and machinists of mining excavating machines. Most often, the ODs occurred when exposed to the severity of labor, fibrogenic aerosols and hand-arm vibration. The development of professional pathology in 98% of cases was due to design flaws of machines and mechanisms, as well as imperfections of workplaces and technological processes. Diseases of the musculoskeletal system (36.2%), respiratory organs (28.9%) and nervous system (22.5%) prevailed in the structure of professional pathology of miners of coal mines. Among the three most common nosological forms of OD were radiculopathy (32.1%), chronic bronchitis (27.7%) and mono-polyneuropathy (15.4%). In 2017, coal miners in the Arctic had a professional morbidity rate of 2.82 times higher than the national rates for coal mining.Conclusions. To preserve the health of miners of coal mining enterprises, technical measures to improve working conditions and medical interventions aimed at increasing the body’s resistance to the effects of harmful production and climatic factors are necessary.

The Impact

An auditor generating potential explanations for an unusual variance in analytical review may utilize a decision aid, which provides many explanations. However, circumstances of budgetary constraints and limited cognitive load deter an auditor from using a lengthy list of explanations in an information search. A two-way between-subjects design was created to investigate the effects of two complementary approaches to trimming down the lengthy list on the number of remaining explanations carried forward into an information search. These two approaches, which represent the same goal (reducing the list) but framed differently, are found to result in a significantly different number of remaining explanations, in both low- and high-risk audit environments. The results of the study suggest that the extent to which an auditor narrows the lengthy list of explanations is important to the implementation of decision aids in analytical review.
