Explaining the Role of Perceived Risk,Knowledge, Price,and Cost in Dry Fish Consumption Within the Theory of Planned Behavior

ABSTRACT

The general purpose of this study is to explore the influence of perceived risk, knowledge, price, and cost of dry fish consumption in Bangladesh using the general framework from the theory of planned behavior (TPB). The field experiments were performed in Bangladesh with a convenience sample of 558 respondents. Multiple regression analysis was used to investigate the relationship among perceived risk, knowledge, price, and cost and TPB constructs. The findings showed that attitude, norms, and procedural knowledge emerge as the key determinants of intention, whereas intention, attitude, norms, and perceived risk have effects on the dry fish consumption frequency. Perceived behavioral control, price, and cost had no significant effect on intention and consumption behavior. The proposed TPB and the extended model both fit the data well and proved the expectations of this study in a promising way. The study found that people are more concerned about potential long-term risk to their family and others. Therefore, management attention should focus on reducing risks which consumers may face through producing safe and hazard-free dry fish.     

Analysis of occupational health hazards and associated risks in fuzzy environment: a case research in an Indian underground coal mine

This paper presents a unique hierarchical structure on various occupational health hazards including physical, chemical, biological, ergonomic and psychosocial hazards, and associated adverse consequences in relation to an underground coal mine. The study proposes a systematic health hazard risk assessment methodology for estimating extent of hazard risk using three important measuring parameters: consequence of exposure, period of exposure and probability of exposure. An improved decision making method using fuzzy set theory has been attempted herein for converting linguistic data into numeric risk ratings. The concept of ‘centre of area’ method for generalized triangular fuzzy numbers has been explored to quantify the ‘degree of hazard risk’ in terms of crisp ratings. Finally, a logical framework for categorizing health hazards into different risk levels has been constructed on the basis of distinguished ranges of evaluated risk ratings (crisp). Subsequently, an action requirement plan has been suggested, which could provide guideline to the managers for successfully managing health hazard risks in the context of underground coal mining exercise.
