The aim of this study is decomposition of the changes in energy consumption with emphasizing the structural changes in Iran during 2001-2011 using Input- Output Structural Decomposition Analysis (I_O SDA). Structural changes in this study represent the changes in structure of intermediate input in sectors and also changes in structure of final demand categories. Structural changes in intermedia...

OF THESIS THE RECIPROCAL PREDICTIVE RELATIONSHIP BETWEEN PERSONALITY AND RISKY BEHAVIORS: AN 8-WAVE LONGITUDINAL STUDY IN EARLY ADOLESCENTS While the overall stability of personality across the lifespan has been welldocumented, there is also evidence of meaningful personality change. This is particularly true when individuals are going through periods of developmental transition. Over time, one...
