Impact of Store Atmosphere on Impulse Buying Behaviour : Moderating Effect of Demographic Variables
Umair Akram,Peng Hui,Muhammad Kaleem Khan,Muhammad Hashim,Shahid Rasheed 보안공학연구지원센터 2016 International Journal of u- and e- Service, Scienc Vol.9 No.7
Impulse buying as an unplanned purchasing decision is influenced by several factors. This study explores the relationship between store atmosphere and impulse buying behavior (IBB). It also examines how demographic variables such as age, gender, and education affect the relationship between store atmosphere and IBB. Mall intercept technique was used to collect data from over seven hundred shoppers from eighteen mega stores in Pakistan using self administered questioners. In order to analyze the data and test the Hypothesis, Structure Equation Modeling (SEM) technique was used. The results suggest that store atmosphere has positive relationship and significant influence on IBB. Additionally, it reveals that only one demographic variable i.e. age has substantial influence on IBB while other variables such as gender and education bear insignificant relationship with IBB. Age moderates the relationship between store atmosphere and IBB. This study is a valuable addition in the existing literature and the findings of the study would be helpful in making different selling and retailing decisions. From a managerial perspective, it is recommended that marketers and the retail managers can considerably enrich the IBB through improving the store environments. In contrast to the common studies that research the impact of store atmospheres on IBB, this research mainly takes into account the demographic variables as moderators.

This study aims to present a parametric analysis of combined use of two surge protection devices in a relatively very long up-pumping water supply pipeline. Transient conditions are induced by sudden pump tripping. The effects of four parameters of hydropneumatic tank, i.e., polytropic exponent, initial air volume, orifice diameter and wave celerity and two parameters of surge tank, i.e., tank volume and tank orifice diameter are investigated on pressure surges. The parameters are optimized to achieve reduced pressure fluctuations throughout the pipe length. A numerical model is developed to perform hydraulic transient analysis in the pipeline system. Governing partial differential equations for unsteady flows are solved by the method of characteristics (MOC) and are subsequently converted into algebraic form using finite difference method. To establish the authenticity of the model, it is experimentally validated by comparing the model results with the experimental results. The validated model is then employed to analyze the effects of various parameters of the two surge protection devices on pressure fluctuations along the pipe length. The results obtained from the study are optimized for safe operation and economic use of the system.
