The impact of environmental variables on efficiency evaluation: a fuzzy DEA approach

Improving the level of public sports services enhances citizens’ physical fitness by implementing the national fitness program. A systematic and scientific efficiency evaluation is a prerequisite for optimizing and improving the level of public sports services in China. Based on data of the Chinese Statistic Yearbook, this study adopted the three-stage data envelopment analysis (DEA) model to measure and analyze the efficiency of public sports services in 31 provinces in China in 2016. To analyze the efficiency of public sports services, technical efficiency was decomposed into pure technical efficiency and scale efficiency. Simultaneously, environmental variables were added to improve accuracy. The results showed that scale efficiency was overestimated, and external technical efficiency was underestimated, before the elimination of external factors and environmental variables. Environmental factors significantly impacted the efficiency of public sports services. Regional gross domestic product (GDP) had a potentially positive impact, while population size partially restricted public sports service efficiency. After eliminating the impact of environmental and random factors, the comprehensive efficiency, pure technical efficiency, and scale efficiency of public sports services all showed improvement in varying degrees. The results provide beneficial insights for the formulation of rational improvement policies for public sports services.

The Impact

A theoretical integration of research concerned with environmental variables and their effects on students’ behavior and performance is presented. The impact of classroom stimuli, such as novelty, color, noise, proximity to teacher and peers on both normal and exceptional children is reviewed. The relation between these sources of classroom stimulation and information sources (i.e., type of task and access to material, person, and role resources) is also discussed. Large deviations from optimal levels of environmental stimulation, which more often occur for exceptional than for normal children, will produce attentional and activity disruptions sufficient to interfere with classroom performance and social interaction.

The Impact

This study examined the occurrence of diabetes and sustainable risk factors in residents aged 30 and above of a community in Taoyuan County, Taiwan. The main purpose of this research was to explore the correlations between related variables and the occurrence of diabetes. The demographic variables, health exam variables, healthy behavior variables, and environmental variables had obvious impacts on the risk of diabetes. As age increased, the risk of developing the disease also increased; higher educational levels lowered risk, while unemployment raised it. Also, analysis of the health exam variables showed that abnormal BMIs, waist-hip ratios, and body fat percentages had significant impacts on individuals’ risk of diabetes. Moreover, it was found that smoking affected the risk of having diabetes: smokers, particularly male smokers, had a relatively higher risk of developing the disease. Lastly, the results showed that exposure to second-hand smoke did not have a significant effect on the diabetes proportion in the male population. However, a significantly higher proportion of females who had been exposed to second-hand smoke had diabetes.

Theoretical Foundations

This research analyzes the sustainability of the convenience stores of the industrial cd in Villahermosa, Tabasco. Considering the behavior of the research variable (sustainability) in different international, national and local contexts. As well as the theoretical foundations on which this variable is based. A diagnosis is made on the sustainability of convenience stores, generating a comprehensive scenario, in order to design a proposal. The tool that was used was the Likert scale from which an instrument was designed to determine how each of the cultural, economic, social, political, technological and environmental variables (independent or context variables) influence the research variable (sustainability of convenience stores). These context variables are in constant changes and movements and directly influence the convenience stores either positively or negatively. The instrument was applied in the convenience stores of the industrial cd of Villahermosa, Tabasco, in order to obtain decisive results for the sustainability of the self-service stores, the Excel tool version 2010 was used, in which tables were obtained and graphics, simplifying the content of the data giving specific and necessary results for the development of the proposal. From the results obtained, a model is designed to improve the sustainability of the convenience stores of the industrial cd in Villahermosa Tabasco, which will achieve a growth that will be strongly linked to social responsibility to provide attention to the workers who are part of them and the reduction of the impact on the surrounding environment. Ensuring the competitiveness profitability and permanence of convenience stores.
