Investigating the Impact of Digital Marketing and Its Effectiveness on Career Growth through Export Performance (Case Study of Top Commercial Companies in East Azerbaijan Province in Iran)

The issue of growth is one of the fundamental issues in economics, which is very important both from a micro and macro perspective. It is no secret that in order to achieve sustainable growth, exports are one of the most fundamental variables, which is the main channel of monetization. For optimal export, you should have a good market share. Digital marketing is one of the most widely used tools to expand the market, so the present study has studied the effectiveness of digital marketing on job growth through export performance. The statistical population of the present study consists of 500 commercial companies in East Azerbaijan province, of which 271 companies have been selected as a statistical sample according to Morgan table and using Cochran's formula. Also, the data collection tool in this study is a questionnaire with Likert scale. Structural equation modeling and SPSS software version 25 and Smart PLS version 3 were used to analyze the data. The results indicate that digital marketing and export performance have a positive effect on job growth and micro and macro development.

Investigating the Mediating Role of Organizational Culture in the Relationship between Transformational Leadership and Organizational Effectiveness

Purpose: The aim of this study was to investigate the effect of transformational leadership dimensions on organizational effectiveness with respect to the mediating role of organizational culture. Methodology: The statistical population of this research is Iranian knowledge-based companies, which at the time of collecting research data, their number is 4551 companies. Data collection method was based on three questionnaires: MLQ leadership styles, Hofstede organizational culture and Parsons organizational effectiveness. The analysis of research data was done through structural equation modeling and using Smart PLS software in two parts: measurement model and structural model. The sampling method used in this study is stratified random sampling method and the sample studied in this study using Cochran's formula, 354 companies were obtained, of which 354 questionnaires were distributed online among these companies and 175 The completed questionnaire was collected for analysis. Findings: The findings of the present study show that the effect of ideal influence and motivational motivation variables on organizational culture and also the effect of organizational culture on organizational effectiveness is positive and significant and also organizational culture mediates the relationship between transformational leadership and organizational effectiveness. Originality/Value: Given that traditional methods of management and leadership, in today's changing and dynamic conditions, lack the necessary effectiveness, so a change in the leadership style of managers and the use of transformational leadership is necessary to achieve organizational effectiveness

The Effect of Road Shoulder and Weather Conditions on the Occurrence of Rollover Crashes in Two-lane Highways

Rollover crash is a type of dangerous crash that occurs often in two-lane highways. Therefore, this study evaluates the effect of road shoulder and weather condition on rollover crashes. Crash data show that 8,609 crashes were recorded from 2006 to 2009 on six two-lane highways located at the center of Iran. This data contains 1860 rollover crashes. Rollover crash in this paper not included the head on crashes and fixed object crashes. Therefore the rollover crashes are only single vehicle crashes. Binary logit was selected for modelling since there were two possible outcomes: rollover crashes and other crash types. The variables of the final model include highway class, road shoulder width, as well as rainy, snowy, foggy and night conditions. The modeling results show that rainy and foggy variables, with coefficients of 0.731 and 0.719 respectively, had the greatest effects on rollover crash occurrence. Also, road shoulder width and night conditions, with coefficients of 0.221 and 0.184 respectively, had the least effects on rollover crash occurrence. Afterward, sensitivity analysis was performed on all the independent variables, and the results show variable variation and indicate that the probability of rollover crash occurrence is 21.29 % on the mentioned highway

Cross Sectional Crash Severity Analysis among Various Vehicle Driver Characteristics

The current study evaluated road crashes in three categories of drivers: passenger car drivers, heavy vehicle drivers and pickup truck drivers. The crash data of road crashes that occurred from 2009 to 2012 in Iranian suburban roads were analyzed. The crashes involved 194,041 damage, 9,677 injury and 1,303 fatality crashes. Because of the ordinal nature of crash severity, ordered logit model was selected for each vehicle driver category. In the passenger car driver category, the independent variables of driver’s gender, driver’s age and driver’s educational level (uneducated, less than high school diploma, high school diploma) were obtained for modeling; in the heavy vehicle driver category, the independent variables of driver’s age and driver’s educational level (uneducated, less than high school diploma) were obtained for modeling, and in the pickup truck driver category, the independent variables of driver’s age and driver’s educational level (uneducated, high school diploma) were obtained for modeling. The variable of driver’s gender with respect to passenger cars shows that crashes by female drivers are more severe than those involving male drivers in suburban roads. Regarding the variable of driver’s age, if the driver’s age increases in each vehicle driver category, the probability of occurrence of a severe crash will decrease. The variable of driver’s educational level shows that the severity of crashes involving a driver that has a low level of education is more compared with a driver that has a high level of education

“On Water” Sonochemical Multicomponent Synthesis of Novel Bioactive 1,1′-(Aryl)bis(2-(cyclohexylamino)-2-oxoethane-1,1-diyl) Di(alkanoates and benzoates)

An expeditious, efficient, and ecofriendly ultrasound-promoted synthesis of a series of novel 1,1′-(aryl)bis(2-(cyclohexylamino)-2-oxoethane-1,1-diyl) di(alkanoate and benzoate) derivatives (6a–k), as useful building block candidates for natural products and drugs, is reported. The target compounds were prepared by the reaction of alkyl or aryl carboxylic acid, various bisaldehydes and isocyanocyclohexane in water using one-pot isocyanide-based multicomponent approach. This efficient protocol without using any catalyst furnished the products in short reaction times (4-5 min) and excellent yields (87–96%). The antibacterial activity of the selected products was also examined. Some products showed promising activities
