background and objectives: over the last decade, climate change has been one of the most challenging issues in the scientific papers. studying the impacts of climate change on crop productivity at regional scale will depend on the right estimate of future climate. this estimation is being implemented by climate models and most of them by general circulation models (gcms). this study aims at pre...

Introduction: Acne is a common problem in adolescent and youngage groups, for which several risk factors have been suggested.One of the risk factors is smoking. In studies on the relationshipbetween smoking and acne, conflicting results have been obtained.Method: This study was conducted on 133 male patients whowere visited at the dermatology clinic of Imam Reza hospital dueto acne as the case ...

Reality does not recognize borders. Why we should use the very general term of “reality” and not science, because the borders that we draw are pure delusions, and on the opposite side there is the reality. The laws of the universe, either the physical nature of the world which the scientist studies or metaphysics which is the territory of philosophers, it isthe same reality that rules. Today ma...

The nuclear research facility in Israel was built in the 1950s amidst great secrecy. Beginning in the 1980s, nuclear research facility workers who contracted cancer began to seek expert medical opinions and take legal action to seek compensation. Because of the secrecy surrounding the work practices and materials used at the research facility, a situation arose in which workers seeking compensa...

We consider a mean-variance general equilibrium economy where the expected returns for controlling and non-controlling shareholders are different because the former are able to divert a fraction of the profits. We find that when investor protection is poor, asset return correlation affects ownership structure in a positive way. Higher return correlation lowers the benefits of diversification wh...

This causal-comparative study evaluated a 30-week chess instructional program implemented within special education math classes for students in the sixth, seventh, and eighth grades in a suburban middle school located in the southwestern United States. An analysis of covariance (ANCOVA) was utilized to compare the adjusted means for the comparison and treatment groups on the students’ math achi...

Cumulative Prospect Theory (PT) introduced the weighting of probabilities as an additional component to capture risk attitudes. However, this addition would be a less significant challenge to expected utility theory (EU) if utility curvature and probability weighting showed strong positive correlation. In that case the utility curvature in EU alone, while not properly describing risky behavior ...

This study was conducted in order to determine motivations and to identify its relationship with socioeconomic conditions of male and female participants in public exercises in the city of Tabriz. To do this, a sample containing 200 people was selected by simple randoming from statistical population. To collect information, we used SMS-6 Malite cliford et.al questionnaire for recognition of mot...

IntroductionStress, a universal phenomenon, affects an individual’s productivity either by increasing it (‘eustress’) or decreasing it (‘distress’). It is widely acknowledged that the medical fraternity is predisposed to enormous stress. The same may be true for the budding medicosthe undergraduate medical students. In our study we attempted to identify situations that predisposed the medical s...
