Research findings have demonstrated a statistically significant negative correlation between profitability, growth, and liquidity and the capital structure measured by the debt ratio. Although it also decreases with non-debt tax shields, this variable does not have statistical meaning with the dependent variable. Size is the only variable with a positive correlation coefficient, but no statistical significance was found either. The results of the study can help these firms build a reasonable capital structure to enhance their intrinsic value.

Present study is ascertain to elaborate the role of green supply chain management towards the suppliers’ performance. Further, the role of social capital as a potential mediator is also explored in the Thai business to business (B2B) context. Data was collected by using the survey questionnaires. Different statistical tests for measurement model and hypothesis testing respectively. Findings highlighted that suppliers’ performance both in environmental and operational terms improves due to the GSCM practices.

Ebook "Partitions, hypergeometric systems, and dirichlet processes in statistics" focuses on statistical inferences related to various combinatorial stochastic processes. Specifically, it discusses the intersection of three subjects that are generally studied independently of each other: partitions, hypergeometric systems, and Dirichlet processes. The Gibbs partition is a family of measures on integer partition, and several prior processes, such as the Dirichlet process, naturally appear in connection with infinite exchangeable Gibbs partitions.

The study showed that the acceptance level of the observed variables reached the Cronbach's Alpha confidence level above 0.7 and the Corrected Item - Total Correlation value of the accepted observed variable over 0.3. Research results with the absolute value of factor loading above 0.5 are optimal, and the observed variables are statistically significant. This study has identified the observed variables for the factors of the theoretical framework. The study results can establish a measurement for further quantitative research with an expanded research scope in the future.

The objective of this study is to design and constitute a system capable of measuring the rate of satisfaction among customers which in particular can be applied in municipalities. The statistical pool of the current research is divided in two groups: First, are university professors and experts qualified. Second, are municipalities customers. The method of data collection determined for the first group was nonprobability and random sampling and the scope and limitation of this data was specified through the application of the central limit theorem.

Born from multidisciplinary roots that include logistics, marketing, management, and sociology, SCM has developed into a distinct field of study over the past fifty years. SCM theory has only recently reached a state of maturation where it produces operationalisable concepts and tools, but progress is being made in advancing both the overarching field of SCM and the specific issues that fall under the SCM umbrella. The authors investigated supply chain strategy as an active longevity’s policy and quality of life of elderly population in the Russian Federation.
