Thermal power stations apart from being source of energy supply are causing soil pollution leading to its degradation in fertility and contamination. Fine particle and trace element emissions from energy production in coal-fired thermal power plants are associated with significant adverse effects on human, animal, and soil health. Contamination of soil with cadmium, nickel, copper, lead, arsenic, chromium, and zinc can be a primary route of human exposure to these potentially toxic elements. The environmental evaluation of surrounding soil of thermal power plants in Odisha may serve a model study to get the insight into hazards they are causing. The study investigates the impact of fly ash-fugitive dust (FAFD) deposition from coal-fired thermal power plant emissions on soil properties including trace element concentration, pH, and soil enzymatic activities. Higher FAFD deposition was found in the close proximity of power plants, which led to high pH and greater accumulation of heavy metals. Among the three power plants, in the vicinity of NALCO, higher concentrations of soil organic carbon and nitrogen was observed whereas, higher phosphorus content was recorded in the proximity of NTPC. Multivariate statistical analysis of different variables and their association indicated that FAFD deposition and soil properties were influenced by the source of emissions and distance from source of emission. Pollution in soil profiles and high risk areas were detected and visualized using surface maps based on Kriging interpolation. The concentrations of chromium and arsenic were higher in the soil where FAFD deposition was more. Observance of relatively high concentration of heavy metals like cadmium, lead, nickel, and arsenic and a low concentration of enzymatic activity in proximity to the emission source indicated a possible link with anthropogenic emissions.
Purpose
The purpose of this paper is to investigate the effect of mindfulness meditation sessions on students of higher education in terms of their mindfulness, mindful consumption behavior and life satisfaction.
Design/methodology/approach
Participants of research were higher education students. The research included two studies. The first (screener) study endorsed that mindfulness was higher in students with higher mindfulness meditation frequency. The second study used difference-in-differences experimental design using a treatment and a control group. These groups participated in pre and post-treatment surveys. The treatment was given as guided short mindfulness meditation sessions as suggested by mindfulness guru – Dr Jon Kabat-Zinn. The treatment group received these sessions at the end of regular subject classes for two months.
Findings
The experiment revealed that mindfulness, mindful consumption and life satisfaction change significantly in the treatment group after treatment as compared to the control group.
Research limitations/implications
Limitations of the study included sample size and attrition. In total, 149 students participated in the screener study. In total, 94 students were given pre-treatment survey as per research design and 80 participated in post-treatment survey.
Practical implications
This experiment demonstrated that important traits and behavior like life satisfaction and mindful consumption behavior of higher education students can be improved significantly. The effectiveness of guided short mindfulness sessions, conducted in the classroom environment, was also confirmed.
Social implications
The inclusion of mindfulness in the regular curriculum by policy makers would benefit students, faculty members and overall quality of learning environment.
Originality/value
Though previous researches have separately investigated relationships of mindfulness with life satisfaction, there is a lack of research to show association of mindfulness, mindful consumption and life satisfaction.
