The Determination of a GSM Operator Preference with a Multiple Logistic Regression Analysis: A Youth-Oriented Study at a University in Turkey

Abstract: The magnitude of technological developments can be better understood nowadays in line with the developments particularly in the communication and mobile phone industries. These developments do not only trigger the production of new technology for mobile phones but they also bring forward the issue of conveying this technology to users. The applications and services produced for mobile phones are generally introduced to the market via Global System for Mobile Communications (GSM) operators providing communication services. Users’ benefiting from these applications and services in their mobile phones or from their operators, depends on their preference of a GSM operator that has the capacity to meet the users’ needs. This study has aimed to determine the factors that influence the preference of a mobile phone operator among university students, the most active age group using mobile phones. Both factor analysis and multiple logistic regression analysis are used to determine the influential factors and the degree of influence in the preference of a GSM operator. It has been identified that the most influential variable on the preference of a GSM operator is the communication expenses as a socio-economic factor, whereas the brand factor is the most important variable in deciding which GSM operator service to purchase.

Degradation Kinetics of Anthocyanins in Shalgam Beverage

Abstract: This research was performed to elucidate the effects of temperature on the degradation kinetics of anthocyanins in shalgam beverage. Shalgam beverage was produced according to traditional production method. Then, it was kept at three different temperatures (65°C, 75°C, and 85°C) for 12 hours, and the relevant quantities of anthocyanins were determined thereafter. The research revealed that degradation of the anthocyanins was well described with a 1st-order reaction kinetics model and the R2 values varied in the range of 0.9059-0.9715. Activation energy of the reaction was determined to be 48537 Joule/mole. The half-lives of anthocyanins at 65°C and 75° C, and 85°C were found to be 138.63, 136.72, and 51.57, respectively. Compared the half-life periods at different temperatures, anthocyanins were found to be more resistant at 65°C and 75°C than at 85°C.
