The Relationship

Since the end of the 20th century and the beginning of the 21st century, as a result of the large-scale implementation of the industrialization policy in Azerbaijan, a large number of industrial enterprises with powerful potential have been created. Based on this, the volume of industrial production over the past 10-15 years has increased 2.7-3.0 times. The current state of the country's economy has created ample opportunities for the development of the non-oil sectors along with the oil sector. At the same time, attention is drawn to the variety and speed of work on the extraction of precious metals. Azerbaijan International Mining Company (AIMC) is one such company and is currently engaged in exploration, production and processing at the Gadabay deposit. The high technology used here and the associated equipment and tools emphasize the need to apply and update recovery technologies, as well as various improvements over time. One of the main directions of scientific and practical work carried out here is to increase the resistance of grinding balls to corrosion. The article is devoted to determining the relationship between the wear rate of grinding balls of a semi-autogenous grinding mill and the parameters that control the process. Keywords: industrialization, industrial production, non-oil sector, mining company, drum mill, grinding balls, wear, the relationship between process controllers.

The object of this study is the further development of eco-innovations for the rise of industry and the economy. Emphasis is placed on the growing relevance of "green" incentives in line with climate challenges, the economical use of natural resources, as well as the need for a systematic vision of environmental issues and the implementation of international requirements. The study is based on the work of foreign scientists, international rankings and world best practices for the introduction of modern economic mechanisms of state incentives for greening the economy, green modernization, the transition to a circular model of the economy. There is a difference in the implementation of environmental policy - some local projects in Ukraine and the European approach - with the assessment of eco-innovation, systemic change, the formation of ecosystems, scaling technological solutions. The main methods used in the study are: methods of system-structural analysis, analysis and synthesis, grouping - for preliminary analysis and selection of appropriate tools in the study of the implementation of eco-innovation in Ukraine and EU countries; index valuation method and method of comparative analysis - used in the analysis of public policy to stimulate the company to "green" growth; abstract-logical method - used to establish the relationship between the need to introduce new instruments of public policy in the environmental sphere with elements of large-scale reform in the context of climate modernization of industry and to form a systematic vision of major achievements in implementing international requirements for eco-modernization of industrial enterprises. The paper analyzes the forms of international assistance that can compensate for the lack of available financial resources for the purposes of green modernization of the economy in conditions of limited financial capabilities of the state, intensification of competition for European and international environmental investments. The obtained result - a set of possible tools to stimulate Ukrainian industry - allows more systematic implementation of "greening" of Ukrainian industry, and their implementation and combination in a specific mechanism will determine the success of an industrial socially-oriented economy.

The mining industry is one of the main links in the industry of Azerbaijan and one of the main directions in the non-oil sector. Two companies operate here - Azerbaijan International Mining Company and AzeriGold, which are the determining factors in the country's gold mining. The article discusses the current state and development prospects of this industry. A regression equation is proposed that allows us to establish a relationship between the performance of ball mills and the technological parameters of the grinding process. It was found that the trajectory of the motion of the balls in a complex manner depends on the parameters studied.

Summary: Our meta-analysis focused on the relationship between homocysteine (Hcy) level and the incidence of aneurysms and looked at the relationship between smoking, hypertension and aneurysms. A systematic literature search of Pubmed, Web of Science, and Embase databases (up to March 31, 2020) resulted in the identification of 19 studies, including 2,629 aneurysm patients and 6,497 healthy participants. Combined analysis of the included studies showed that number of smoking, hypertension and hyperhomocysteinemia (HHcy) in aneurysm patients was higher than that in the control groups, and the total plasma Hcy level in aneurysm patients was also higher. These findings suggest that smoking, hypertension and HHcy may be risk factors for the development and progression of aneurysms. Although the heterogeneity of meta-analysis was significant, it was found that the heterogeneity might come from the difference between race and disease species through subgroup analysis. Large-scale randomized controlled studies of single species and single disease species are needed in the future to supplement the accuracy of the results.

In this article, the ''Cold War'' is understood as a situation where the relationship between the leading States is determined by ideological confrontation and, at the same time, the presence of nuclear weapons precludes the development of this confrontation into a large-scale armed conflict. Such a situation has developed in the years 1945–1989, during the first Cold War. We see that something similar is repeated in our time-with all the new nuances in the ideological struggle and in the nuclear arms race.

BACKGROUND The COVID-19 pandemic has impacted nearly all aspects of life and has posed significant threats to international health and the economy. Given the rapidly unfolding nature of the current pandemic, there is an urgent need to streamline literature synthesis of the growing scientific research to elucidate targeted solutions. While traditional systematic literature review studies provide valuable insights, these studies have restrictions, including analyzing a limited number of papers, having various biases, being time-consuming and labor-intensive, focusing on a few topics, incapable of trend analysis, and lack of data-driven tools. OBJECTIVE This study fills the mentioned restrictions in the literature and practice by analyzing two biomedical concepts, clinical manifestations of disease and therapeutic chemical compounds, with text mining methods in a corpus containing COVID-19 research papers and find associations between the two biomedical concepts. METHODS This research has collected papers representing COVID-19 pre-prints and peer-reviewed research published in 2020. We used frequency analysis to find highly frequent manifestations and therapeutic chemicals, representing the importance of the two biomedical concepts. This study also applied topic modeling to find the relationship between the two biomedical concepts. RESULTS We analyzed 9,298 research papers published through May 5, 2020 and found 3,645 disease-related and 2,434 chemical-related articles. The most frequent clinical manifestations of disease terminology included COVID-19, SARS, cancer, pneumonia, fever, and cough. The most frequent chemical-related terminology included Lopinavir, Ritonavir, Oxygen, Chloroquine, Remdesivir, and water. Topic modeling provided 25 categories showing relationships between our two overarching categories. These categories represent statistically significant associations between multiple aspects of each category, some connections of which were novel and not previously identified by the scientific community. CONCLUSIONS Appreciation of this context is vital due to the lack of a systematic large-scale literature review survey and the importance of fast literature review during the current COVID-19 pandemic for developing treatments. This study is beneficial to researchers for obtaining a macro-level picture of literature, to educators for knowing the scope of literature, to journals for exploring most discussed disease symptoms and pharmaceutical targets, and to policymakers and funding agencies for creating scientific strategic plans regarding COVID-19.

We empirically explored the impact of feedback seeking, including feedback inquiry and monitoring, on the coworker feedback environment via coworker identification. Participants were 264 employees who worked in research and development, design, and technology sectors of industrial enterprises in China. The results indicated that feedback monitoring, feedback inquiry, and coworker identification were all positively related to the coworker feedback environment after controlling for the effects of demographic variables. Further, coworker identification fully mediated the relationship between feedback inquiry/monitoring and the coworker feedback environment. Our findings expand understanding of the feedback loop by bridging the gap between coworker feedback seeking and the coworker feedback environment. We recommend that coworkers encourage employees' feedback-seeking behavior so that the workplace feedback environment motivates them to ask for the help they need to work independently.

Reflection about the role of community engagement and corporate social investment in Brazil, associated with the presence of a large economic enterprise, is the major stimulus of this chapter. It seeks to present how cross-sector governance can contribute to the social development of a city and how this process can be led by a partnership comprising a corporate foundation, government, and civil society. The concept of the public–private social partnership (PPSP) is explored: a strategy for building a series of inter-sectoral alliances aimed at promoting the sustainable development of territories where the company has large-scale enterprises, through joint efforts towards integrated long-term strategic planning, around a common agenda. To this end, the case of Canaã dos Carajás is introduced, a municipality in the State of Pará, in the Amazon region, where large-scale mining investment is being carried out by the mining company Vale SA.

Resource Based Theory

In a competitive business environment at the Bottom of the Pyramid smallholders supplying global value chains may be thought to be at the whims of downstream large-scale players and local market forces, leaving no room for strategic entrepreneurial behavior. In such a context we test the relationship between the use of strategic resources and firm performance. We adopt the Resource Based Theory and show that seemingly homogenous smallholders deploy resources differently and, consequently, some do outperform others. We argue that the ‘resource-based theory’ results in a more fine-grained understanding of smallholder performance than approaches generally applied in agricultural economics. We develop a mixed-method approach that allows one to pinpoint relevant, industry-specific resources, and allows for empirical identification of the relative contribution of each resource to competitive advantage. The results show that proper use of quality labor, storage facilities, time of selling, and availability of animals are key capabilities.

Abstract Background Epidemiological studies of the relationship between gallstone disease and circulating levels of bilirubin with risk of developing colorectal cancer (CRC) have been inconsistent. To address possible confounding and reverse causation, we examine the relationship between these potential risk factors and CRC using Mendelian randomisation (MR). Methods We used two-sample MR to examine the relationship between genetic liability to gallstone disease and circulating levels of bilirubin with CRC in 26,397 patients and 41,481 controls. We calculated the odds ratio per genetically predicted SD unit increase in log bilirubin levels (ORSD) for CRC and tested for a non-zero causal effect of gallstones on CRC. Sensitivity analysis was applied to identify violations of estimator assumptions. Results No association between either gallstone disease (P value = 0.60) or circulating levels of bilirubin (ORSD = 1.00, 95% confidence interval (CI) = 0.96–1.03, P value = 0.90) with CRC was shown. Conclusions Despite the large scale of this study, we found no evidence for a causal relationship between either circulating levels of bilirubin or gallstone disease with risk of developing CRC. While the magnitude of effect suggested by some observational studies can confidently be excluded, we cannot exclude the possibility of smaller effect sizes and non-linear relationships.

AbstractThe relationship between a firm and its supply chain has been well studied, however, the association between the position of firms in complex supply chain networks and their performance has not been adequately investigated. This is primarily due to insufficient availability of empirical data on large-scale networks. To addresses this gap in the literature, we investigate the relationship between embeddedness patterns of individual firms in a supply network and their performance using empirical data from the automotive industry. In this study, we devise three measures that characterize the embeddedness of individual firms in a supply network. These are namely: centrality, tier position, and triads. Our findings caution us that centrality impacts individual performance through a diminishing returns relationship. The second measure, tier position, allows us to investigate the concept of tiers in supply networks because we find that as networks emerge, the boundaries between tiers become unclear. Performance of suppliers degrade as they move away from the focal firm (i.e., Toyota). The final measure, triads, investigates the effect of buying and selling to firms that supply the same customer, portraying the level of competition and cooperation in a supplier’s network. We find that increased coopetition (i.e., cooperative competition) is a performance enhancer, however, excessive complexity resulting from being involved in both upstream and downstream coopetition results in diminishing performance. These original insights help understand the drivers of firm performance from a network perspective and provide a basis for further research.
