The increase in the number of universities for the last decade in Iran increases the need for higher education institutions to manage their enrollment, more effectively. The purpose of this study is to design a model to improve the first year university student adjustment by examining the effects of academic self-efficacy, academic motivation, satisfaction, high school GPA and demographic variables on student’s adjustment to university.

This paper presents an empirical investigation to study the effects of macro-economic factors on the performance of stocks listed on Tehran Stock Exchange (TSE). The proposed study considers the effects of money supply, inflation rate, oil price, unforeseen changes in the course structure of interest rates as well as unanticipated changes in industrial production on stock price.

In other words, Arbitrage pricing theory model describing the expected return per share is reasonable and macro-level variables explain systematic risk on TSE.
