Purpose This paper aims to examine the mediating role of environmental concern in the relationship of green purchase awareness and purchasing behavior of fast food consumers keeping in view the theory of planned behavior. Design/methodology/approach A quantitative, cross-sectional design is used by collecting primary responses through a validated questionnaire. In all, 1,008 male and female buyers of fast food were sampled. Structural equation modeling is applied. Findings The results revealed that green purchase awareness has a positive relationship with green purchase behavior, and environmental concern has no mediation in the relationship. Upon having awareness, the respondents adopted green or pro-environmental behavior, but at the same time, they were found having least concern for the protection of environment. Research limitations/implications This is a cross-sectional study with questionnaire. Multiple sources of data collection results in weakening self-reporting bias. Practical implications Implications count toward individuals, enterprises and society at general. Originality/value The study highlights the issue of not having concern for the protection of the environment even after having green purchase awareness. This is the first time the environmental concern is examined as a mediator in the selected relationship. The contradictory results of having no environmental concern differentiate this study from others.

Purpose – The aim of the study is to investigate the impact of job stress on job satisfaction of employees and also to find out the drivers for the job stress, which contribute to create job stress which ultimately negatively affect job satisfaction. Design/methodology/approach – The study is mainly based on review of the existing literature and collection of data through an adopted questionnaire survey, conducted from the selected sample of Air Traffic Controllers of Pakistan Civil Aviation Authority. A total of 134 questionnaires were distributed among the sample which is selected using the technique of cluster sampling. 122 respondents returned the questionnaire, which are utilized for the analysis purpose. Findings – The results of the current study indicate that there is a negative relationship between job stress and job satisfaction. Those air traffic controllers who had high level of job stress had low job satisfaction. Research limitations – This research paper is based on a specific case of Air Traffic Controllers of Pakistan Civil Aviation Authority. So the results are applicable specifically to Air Traffic Controllers of Pakistan Civil Aviation Authority or other fields in the same industry. A quantitative methodology is used to investigate the problem. Future research can investigate the problem by using a mix of quantitative and qualitative research methodology. Practical implications – The practical implications of the paper include implementation of the results provided by researcher to decrease the employees’ level of stress and increase job satisfaction level. Originality/value – The study is conducted first time in the field specifically highlighting the stress issue. It can be a base for the future research in this area.   Keywords – Job Stress, Job Satisfaction, Air Traffic Controllers

In this paper, we obtain some fixed point theorems for fuzzy mappings in a left K-sequentially complete quasi-pseudo-metric space and in a right K-sequentially complete quasi-pseudo-metric space, respectively. Our analysis is based on the fact that fuzzy fixed point results can be obtained from the fixed point theorem of multivalued mappings with closed values. It is observed that there are many situations in which the mappings are not contractive on the whole space but they may be contractive on its subsets. We feel that this feature of finding the fuzzy fixed points via closed balls was overlooked, and our paper will reopen the research activity into this area.
