Influence of entrepreneurs on job satisfaction and organizational commitment of employees

In this paper, we analyze reliability, correlations, regression of employee obligations, compare employee regression, job satisfaction regression, and hierarchical regression analysis. As techniques for comparison of entrepreneurs and employees are significant for analysis of positive correlations between the determinants, we used 36 independent samples and 210 individuals. The findings reveal that: (1) The results of the research confirmed the existence of a statistically significant positive correlation between the determinants of job satisfaction and organizational commitment on one hand, and the work of entrepreneurs, on the other; (2) The results of the survey compare the relationship between entrepreneurs and employee job satisfaction and organizational commitment, adding a significant increase in the importance of the construct; (3) Entrepreneurship has a relative correlation in relation to job satisfaction, and organizational commitment, and thus increases the scope of tasks and efficiency of entrepreneurs; (4) Entrepreneurs show dominance over employee satisfaction and organizational commitment, when they predict the success of a group or organization and organizational civic behavior. We recommend that future researches examine the relationship among entrepreneurs and their relationship with employees, as well as job satisfaction and organizational commitment, in order to potentially compare them.

Impact of quality on improvement of business performance and customer satisfaction

In an immense market struggle, the only effective way to build a long-term competitive advantage is to provide a high level of quality. Offering quality to the market, the organization creates loyal consumers on the basis of which it achieves its profitability, growth and development. The research presented in this paper is aimed at determination of the impact of quality on improving business performance and customer satisfaction. Correlation analysis confirmed this influence on the basis of obtained statistically significant mutual relations between the analyzed variables. Quality was shown to have an impact on improving the business performance of the organization, primarily on profitability through the improvement of leadership and relationship management. The impact of quality on customer satisfaction was also confirmed, where the engagement of people and the management of mutual relations had the greatest impact on consumer confidence. The research confirmed that the training of employees in terms of quality had a statistically significant impact on improving customer satisfaction, if it is conducted in an efficient manner.

Interpreting relationships between pollutants and carbon dioxide emitted into air from industries in Serbia

The focus was on the pollution problem in Serbia and the relationships between CO2 emitted into air from industries and air quality indicators such as particulate matters (PM2.5, PM10), nitrogen and sulfur oxides (NOx, SOx), and volatile organic compounds were analyzed. To identify the dependencies, both parametric and nonparametric statistical learning-based evaluation algorithms were taken into consideration. Both the model structures produced satisfactory estimations with high accuracy levels. As a result of the model interpretation, PM2.5 has been recorded as the main indicator to explore the variability in CO2 concentrations. The implementations exhibited that interpretable machine learning can provide meta-data and sufficient information for making blackbox air quality system more explainable. Thus, the practiced modelling tools, the provided interrelationships as well as the new information could be considered by the national authorities within a computational environmental management strategy.

Evaluation of product quality with decibels

In modern Quality Engineering, the quality of process results, the quality of measuring instruments, and the quality of completed processes are considered according to their quality characteristics. However, in traditional engineering, only the quality of measuring instruments and the quality of completed processes (precision or accuracy indices PCI, PPI) can be successfully defined, while the quality of process results (semi-finished product, product, software, service) can only be described (has or does not have the required quality), good or bad quality, better or worse quality). In the modern consideration of quality, the quality of process results is now defined by the number of decibels [dB], according to the discovery of the genius Japanese scientist Genichi Taguchi (1924-2012), with the methods of Robust Technology Development and Standard Ratio (S/N). This paper discusses definition of the quality of process results with one input variable and continuous characteristics with three illustrative examples.

Factors influencing insurance for young people

Present times are changing rapidly, people are becoming increasingly active, and we often find ourselves in a situation over which we have no control. Nowadays we know many types of insurance with which we can take care of our financial security. It is important for individuals to choose the most appropriate type of insurance according to their needs and life span. It is extremely important for young people to start saving for their future as soon as possible in the type of life insurance. The main objective of this paper is what proportion of young people already have insurance or are already thinking about it and why not. We were also interested in what the decisive factors are that make young people decide to buy insurance and why not. Research has shown that young people are aware of the importance of insurance, but most of them do not have adequate financial resources and are insufficiently informed about the types of insurance.

Review of methods for migrating software systems to microservices architecture

Majority of software systems in business use, known as legacy systems, have monolithic structure hard to maintain and upgrade with new features. The most common option to overcome this situation is reengineering of existing software systems, which can be perform in different ways and with different outcomes. One of the recent most popular approaches is migration to microservices architectures, which makes distribution of software functionalities in small and independent units possible. Each unit, called microservice is self-contained and independent, which makes system manipulation and modification easier. Several methods for migration to microservice architecture have recently been proposed. This article presents a review of methods for migrating existing systems towards microservices. In addition, this article presents software artifacts affected by migration methods and used algorithms. Implications and benefits of the presented study, as well as validity issues are discussed, followed with concluding remarks and future research directions.
