The Impact

For modern information systems for modeling and monitoring the labor resources, as well as to ensure the quality of a special assessment of working conditions, it is necessary to study the impact of the labor intensity and adapt methods for analyzing the non-production losses from temporary disability of employees. The authors supplemented the previously presented mathematical model for non-productive losses of working time from diseases and industrial injuries of workers engaged in dangerous and harmful working conditions with normal and increased intensity. Also, the shortcomings of the automated modeling system based on the flow model, which led to distortion of the research results, were eliminated. The influence of the labor intensity in harmful production conditions on human health is taken into account. The developers conducted experiments with the data of the automated information management system of a construction enterprise, where employees are engaged in the construction of main gas pipelines in various regions of Russia. The practical significance of the research results is formulated: the changes made to the system significantly improve the quality of special assessments of working conditions, regularly conducted at enterprises, as well as the quality of the labor norms setting. The application of the presented modeling system is especially relevant in the context of the coronavirus pandemic, when it is necessary to accurately determine the risk groups of workers.

Introduction.Methanol and its derivatives occupy one of the leading places among the main organic synthesis intermediates in terms of their importance and scale of production. According to experts, by 2027 the global demand for methanol can reach 135 million tons, the annual growth will be about 5.5%. However, there is little information regarding the assessment of working conditions and occupational risks for workers in modern methanol production and its derivatives.The aim of the studyis hygienic assessment of working conditions and the formation of health risks in workers of modern production of methanol and methylamines.Materials and methods.The assessment of the main adverse factors of production is given. When studying the state of health, objective indicators (the results of an in-depth medical examination) and subjective (the results of a quantitative assessment of the risks of the main pathological syndromes associated with health) are considered.Results.According to long-term observations, the concentration of harmful substances in the air of the working area, indicators of labor severity, parameters of physical factors met hygienic requirements, with the exception of industrial noise exceeding the maximum permissible level, as well as labor intensity of 1 degree. The General assessment of working conditions corresponds to the category of harmful 2 degrees (3.2). According to the results of the medical examination and quantitative assessment of the risks of health disorders in workers, the most significant were functional disorders and diseases of the circulatory system. The levels of somatic pathology on the part of the main body systems were significantly higher in apparatchiks compared to the engineering and technical personnel (ETP).Conclusions:In the production of methyl alcohol and methylamines, the main hygienic importance is the impact on workers of the complex of harmful substances of 1-IV hazard classes in low concentrations, increased levels of industrial noise, labor intensity of 1 degree. According to the subjective assessment of health and medical examination, the greatest prevalence of health risks in workers was observed from the circulatory system, and the levels of the revealed somatic pathology were statistically significantly higher in apparatchiks compared with the ETP.

Reducing the duration of construction works requires additional organizational measures, such as selecting construction methods that assure a shorter realization time, engaging additional resources, working overtime, or allowing construction works to be performed simultaneously in the same working units. The simultaneous work of crews may affect the quality of works and the efficiency of construction processes. This article presents a simulation model aimed at assessing the impact of the overlap period on the extension of the working time of the crews and the reduction of a repetitive project’s duration in random conditions. The purpose of simulation studies is to provide construction managers with guidelines when deciding on the dates of starting the sequential technological process lines realized by specialized working crews, for sustainable scheduling and organization of construction projects.

Domestic Violence And Abuse

Abstract Background The COVID-19 pandemic and lockdown evoked great worries among professionals in the field of domestic violence and abuse (DVA) as they expected a rise of the phenomenon. While many countries reported increased DVA, the Netherlands did not. To understand this discrepancy and the overall impact of the lockdown on DVA support services, we interviewed DVA professionals about their experiences with DVA during the rise of COVID-19, the impact of the lockdown on clients and working conditions, and views on eHealth and online tools. Methods Semi-structured interviews were conducted among 16 DVA professionals with various specializations. This data was analyzed using open thematic coding and content analysis. Results Most professionals did not see an increase in DVA reports but they did notice more severe violence. They experienced less opportunities to detect DVA and worried about their clients’ wellbeing and the quality of (online) care. Furthermore, their working conditions rapidly changed, with working from home and online, and they expressed frustration, insecurity and loneliness. Professionals feel eHealth and online tools are not always suitable but they do see them as an opportunity to increase reach and maintain services when physical contact is not possible. Conclusion This study suggests DVA was probably under-detected during the lockdown rather than not having increased. The Dutch system heavily relies on professionals to detect and report DVA, suggesting a need for critical evaluation of the accessibility of professional help. Professionals experienced significant challenges and should themselves be supported psychologically and in their changed work practices to maintain their ability to aid survivors.

Purpose As an important part of the disclosure of listed companies' annual reports, MD&A will disclose some "bad news" about the company. The purpose of this paper is to study whether such "bad news" can reduce information asymmetry and alleviate the risk of stock price crash remains to be seen. Design/methodology/approach Based on the sample of A-share listed companies from 2007 to 2016, the authors examine whether the negative information in MD&A could reduce stock price crash risk. Findings It is found that the negative information in MD&A does not reduce future crash, which indicates that the negative information in MD&A does not alleviate the information asymmetry. Further, it is also found this is due to the low readability of negative information which leads to the negative information not successfully released into the market timely. Only highly readable negative information can alleviate information asymmetry and suppress crash risk. In addition, the authors also find in the companies with more investor surveys negative tone is negatively correlated with crash risk, which means that investor surveys could help investors interpret the negative information in MD&A and alleviate stock price crash risk. Practical implications The practical significance of this article: this paper suggests that investors should carefully identify the quality of negative information in MD&A and pay attention to other quality characteristics besides credibility. This paper suggests that the regulator should pay attention not only to whether to disclose and the amount of disclosure but also to the quality of information disclosure, such as readability, so as to restrict management's strategic behavior in information disclosure. Originality/value First, different from previous studies on the impact of information disclosure on crash risk, this paper directly explores the impact of information in MD&A on stock price crash risk from the perspective of negative information disclosure that management most want to hide. It supplements the literature on the impact of information disclosure on stock price crash risk. Second, this paper studies the interaction between information tone and readability and its impact on the risk of stock price crash. Some studies believe that the credibility of negative news is higher and investors' reaction may be stronger. However, this paper finds that the disclosure of negative information may not be absorbed by the market because of the low readability. Third, this paper finds that investor surveys can help information users to interpret negative information and alleviate the risk of stock price crash, which shows that information disclosure of different channels will complement each other and improve information efficiency. Therefore, it advocates different information disclosure channels which has important practical significance for improving market pricing efficiency and reducing investment decision-making risk.

Harmful Effects

In accordance with the existing Federal sanitary standards, noise and infrasound are considered to be an harmful production factor and in terms of their prevalence they occupy a leading place in the national economy. To prevent the harmful effects of noise and infrasound on the health of members of the armed forces establishes the main lines. For prognostic assessment of harmful influence of production factors on production facilities and transport the special assessment of working conditions is carried out without fail. Hygienic research of workplaces has shown that noise and infra-sound levels correspond to harmful and dangerous classes, that is, risks of professional pathology of acoustic Genesis are created. The presence of acoustic sources in the Armed forces requires constant monitoring of them, the annual special assessment of working conditions development of preventive measures. The impact of noise and infra-sound leads to a decrease in military and professional performance and an increase in General and professional morbidity. The leading place in the structure of morbidity of noise etiology is a sensorineural hearing loss. This requires further improvement of the provision of specialized assistance to military personnel in the presence of noise hearing loss. In the current regulations of the military medical services noise and infrasound are not identified as a harmful factor, and therefore not fully developed the issues of professional selection, monitoring and medical examination of noise pathology. An important place in the system of prevention of harmful effects of noise is given to the means especially individual of protection against noise. Their absence and low efficiency pose a threat to the acoustic safety of military personnel. Provision of personnel with means of individual protection against noise and control of the correctness of their operation are the most relevant measures to reduce the noise pathology of the hearing organ. The existing system of measures to combat the harmful effects of noise in the Armed forces requires revision in accordance with the existing state legislative and legal framework.

This paper describes the selected demographic characteristics as moderators of the impact of the quality of interpersonal relationships at work on counterproductive work behaviours. The main purposes of the research are describing: 1) how interpersonal relationships at work influences the intensity of counterproductive work behaviours; 2) how sex, age, education, length of service and type of job moderate the influence of interpersonal relationships at work on counterproductive work behaviours; 3) how the above-mentioned demographic characteristics influence interpersonal relationships at work and counterproductive work behaviours separately. The studies on the literature indicated that there were no comprehensive research results concerning those problems. The research paper fills a gap in the literature relating to the impact of interpersonal relationships at work on counterproductive work behaviours and the relation to modelling this impact by demographic characteristics of employees (sex, age, education, length of service, type of job). To achieve the study purposes, the author conducted a survey conducted on a sample of 1336 active employees in Poland. The survey period was 2018-2019. The IBM SPSS Statistics and IBM SPSS Amos were used to analyze data. Based on Structural Equation Modelling, it was that:1) interpersonal relationships at work negatively impacted on the intensity of counterproductive work behaviours against another individual; 2) the strength of influence of interpersonal relationships at work on counterproductive work behaviours did not change relevantly in modelling with selected demographic characteristics (sex, age, education, length of service, type of job); 3) only education, current kind of job and service length had a relevant influence on interpersonal relationships at work and counterproductive work behaviours. The research results could be useful for managers. In their activities, managers should systematically monitor interpersonal relationships at work and counterproductive work behaviours taking into account employees' demographic characteristics. In this process, managers should pay particular attention to education, type of current job, and service length.
