Online searching for product information or buying some certain goods online has become increasingly popular during the last few years. Despite this fact there is still little empirical evidence about the relationship between in-store shopping and e-shopping. The substitution effect between these two types of shopping can have significant outcomes in urban transportation. Hence Analyzing different aspects of this new phenomenon and using its potential substitution effect on in-store shopping to decrease the amount of mobility in transportation system can be an attractive subject for urban transportation planners. The main purpose of this study is to reveal the relationship between the... 

The purpose of this study was to investigate the attitude of young people towards luxury brands from the point of view of social identity (Case study: Luxury cars shopping in Tehran by young people).In this regard, while reviewing the concepts of attitude and luxury brands dimensions, using the method of regression and structural equation modeling, we investigated the attitude of young people towards luxury brands.The statistical population of this research includes customers of Del's Brandy Benz and BTBMW District 1 in Tehran. Their number is estimated to be 500, and the sample size is determined using Morgan Crujsi's table to determine the sample size of 217 people. Using the Simple random... 

Traffic accidents are one of the most important issues of traffic which impose high costs to societies. Regardless of accidents material costs, disabilities and deaths are very considerable. Iran statistics show that death rates caused by driving accidents are two times more than world statistics and each 25 minutes one dies because of driving accidents. Researchers classify factors influencing driving accidents in four categories: human factors, factors related to the environmental conditions, factors related to the vehicles and factors related to the roads. Driver behavior and characteristics are the main human factors that influence his or her behavior. The aim of this study is analyzing... 

Teaching a foreign language and its culture implicitly might result in internalizing the foreign culture and identity (Brown, 2001). This might consequently cause cultural identity crisis and loss in a broader sense. As provided by Eslami Nodooshan (1998), considering the importance of cultural awareness raised through cultural studies and its influence on language policy and accordingly language classes provided the ground for this study to investigate the components of Iranian cultural identity, the degree of Iranian EFL teachers’ cultural identity, and the statistically significant difference between the Iranian EFL teachers’ cultural identity with different demographic characteristics.... 

The results of the conducted research indicate that although there is a period of time for pedestrians to cross the street safely at signalized intersections, some pedestrians cross the street when they find a space between the passing cars even though their traffic light is red. This behavior has caused a great increase in the number of pedestrian accidents. Understanding pedestrians’ behavior can be helpful in reducing these types of accidents.In order to analysis the pedestrians behavior while crossing the street two types of data were collected; a field questionnaires and a concurrent video image recordings of the pedestrians crossing the streets.The 435 questionnaires collected... 

Crash severity is among the fundamental safety indicators in transportation. In recent years, distracted driving has been one of the biggest concerns in road crashes. Many scholars have evaluated the effects of distraction in crash severities and injuries. This study uses the latest general estimates system (GES) crash dataset, which is a subset of the US National Automotive Sampling System (NASS) and the structural equation model (SEM) approach to explore the relationships between distraction factors and crash severity in male and female drivers. Using SEM for modeling about 22 thousand observations offers the opportunity to simultaneously examine complex relationships between variables by... 

The importance of a quick and authentic response in today's hectic business environment shows us the necessity of being alert. By understanding the value of alertness, we seek to find factors affecting it. In this article, we try to learn about new aspects of this structure. We expect that personality attributes and the way we look at the environment are influential in this matter. The amount of "curiosity" that is institutionalized in our personality and our "attitude" towards entrepreneurship has often been examined along with other concepts like mindfulness. However, the exact relationship between them has not been specifically analyzed. For this purpose, we started this research by... 

Drivers' behavior is an influential factor in more than 90% of driving accidents. Due to the increased traffic load due to the use of private cars, as well as traffic congestion restrictions for the use of private cars at large city centers, the use of public transportation means for transportation of goods and passengers in order to reduce traffic load is a very convenient option and it is sometimes necessary. Therefore, it is very important to examine the behavior and character of drivers of public urban vehicles in order to increase traffic safety. The purpose of this research is to present and develop a descriptive model that describes the behaviors leading to at-fault accidents for...
