OBJECTIVES The aims of this study of Japanese married employees were: 1) to examine the relationship between work-related factors and work-to-family conflict (WFC); 2) to examine the relationship between WFC and fatigue and depression; and 3) to explore the role of family togetherness in a path between WFC and health. METHODS A cross-sectional survey was conducted among employees belonging to...
The chemical industry is very important for the world economy and this industrial sector represents a substantial income source for developing countries. However, existing regulations on controlling atmospheric pollutants, and the enforcement of these regulations, often are insufficient in such countries. As a result, the deterioration of surrounding ecosystems and a quality decrease of the atm...
It is necessary to research on how to manage risks in Chinese chemical industry supply chain effectively. After analyzing supply chain risks and mitigation strategies in Chinese chemical industry supply chain, firstly this paper defines the supply chain risk management problem in Chinese chemical industry. Then this paper develops a stochastic chance-constrained programming model to select opti...
ca. 220 words). After the reunification, drastic economic restructuring processes occurred in East Germany due to a double transition: the transformation of the political and economic system, and the Fordist crisis associated with ongoing globalisation processes. The challenges and shifts were particularly strong in the chemical industry, which had developed a structure of mass production chara...
Glucaric acid is a kind of organic acid and widely used in food, medicine and chemical industries. During the past decade, model microorganisms such as Escherichia coli and Saccharomyces cerevisiae have been engineered for production of glucaric acid. Especially, Pichia pastoris has also been engineered for production of glucaric acid with the highest reported value. In this commentary, recent ...
The chemical industry, considered as the first to have had a scientific base, constitutes a very heterogeneous sector. Molecular biology is complemented by the chemical industry in its steps, and the integration of two sciences have formed the young biotechnology sector, which is indivisible. In addition, the development of companies from 1920s to now results in the emergence of large multinati...
IN T RO DU C T IO N To maximize return on investment, the chemical industry is challenged to bring new products to the market while improving productivity. In many cases, developing a new product or a new process with only a small percentage increase in the yield can result in significant increases in earnings for the company. To develop new chemicals and improve organic synthesis efficiency, t...
Social Comparisons of Wage Increases and Job Satisfaction* We combine status quo and social comparison considerations and investigate whether relative wage increases in the sense of differences between individual wage increases and wage increases of comparable employees are related to managers’ job satisfaction. Using a panel data set of managers in the German chemical industry, we indeed find ...
Microbial exopolysaccharides (EPS) are a structurally very diverse class of molecules. A number of them have found their application in rather diverging fields that extend from medicine, food, and cosmetics on the one side to construction, drilling, and chemical industry on the other side. The analysis of microbial strains for their competence in polysaccharide production has therefore been a m...
