Globalization and high-tech processes, through information technology, have doubled the pressure on service organizations in the private and public sectors to compete in new services. In developed economies, the service sector is responsible for most employment and value-added growth. As a result, more extensive studies on the development of new services and the factors influencing it are becoming more important. On the other hand, value creation is a new concept in business, marketing and innovation of organizations that has been considered with the aim of creating a competitive advantage to maintain the survival of organizations. Sharing value creation is actually the process of creating value through the interactions of organizations with other organizations, employees, customers and other partners in the market and today is the focus of managers of service organizations including the banking and insurance industry, which are central pillars of economies. The present study seeks to provide a model to investigate the impact of shared value creation directly and indirectly on the development of new services, the impact of internal coordination as a mediating factor between the two variables of value creation and new service development as well as technology experience variable as moderator of internal coordination in 41 branches. It has been done from the central branches of banks and insurance companies of Boroujerd city. This research is of an applied type with a survey strategy. Data were collected through a questionnaire and also structural equation method was used to analyze the data. The results show that the creation of shared value has both a direct and indirect positive and significant effect on the development of new services. Also, the mediating role of intra-organizational coordination and moderation of technology experience was confirmed.

The purpose of this research work was to identify and analyze the factors affecting the men professional athlete's satisfaction in sport teams based on a systemic approach.
The research method used was descriptive, and the population was 776 Iranian athletes in four sport teams including soccer, volleyball, basketball, and handball, who participated in a superleague. The sample was selected randomly and 360 of them responded to a researcher-made questionnaire. After a literature review, the questionnaire consisted of 86 items on five-value Likert whose face validity was confirmed by 17 sport management specialists and other experts, and their reliability was estimated with Cronbach's alpha ( = α 0.98). The data was analyzed through factor analysis with orthogonal rotation, Freedman, and Sign tests.
Findings showed the structure of men athlete's satisfaction including antecedents, processes, outcomes, and correlate factors that were detected from the athlete's satisfaction variance, respectively. Also the outcomes and process factors had high priorities in fulfilling the athlete's satisfaction. On the other hand, the life quality, personal performance, organizational processes, and work life quality criteria had high variance in the athlete's satisfaction, respectively. Among the items, commitment and loyalty, cohesion and citizenship behavior, social support by fans and media, and club services had high priorities in fulfilling the athlete's satisfaction.
The personal and group processes and outcomes have high importance in fulfilling the athlete's satisfaction but the outcomes are more influenced by environmental factors. Thus club and team processes are very important in athlete's satisfaction.

The purpose of the present study was to investigate the impact of coach changes on the performance of football clubs in the Iranian premier league.
The statistical community of the present study contained all the clubs that participated in 12 seasons of Iranian football clubs premier league from 2001 to 2013. The whole data was extracted from the archive of Iran premier league organization and the Foolad Mobarakeh Sepahan sport club. Improvement or degradation of football clubs in each season compared to the previous season based on coach changes or stability was investigated. The data was analyzed with one-way Anova using the Gabriel post hoc test and the independent sample t-test in a significance lower than 0.05.
The results obtained demonstrated that coach stability had a significant effect on the improvement of performance, and successive changes of coaches had a significant impact on degradation of performance. These results showed that the coach changes caused a 1.48 decline in their rank on the league schedule, and coach stability caused a 1.19 improvement in their rank on the league schedule.
Generally, analysis of the results supported the hypothesis that coach stability provided enough time for employing new players and implementation of their tactics and work philosophy that eventually improved the performance of the clubs.

In today competitive environment, increasing supply chain efficiency has considerable importance in success of firms. Various factors limit this increase, which are referred as supply chain complexities. Identification of these complexities and dealing with them is essential. This paper attempts to introduce and apply an efficient and effective method for dealing with complexity of supply chain. This method is based on systemic principles of theory of constraints. This research shows how a manager can use logical tools of theory of constraints thinking processes (TOC TP) to identify and deal with root causes of supply chain complexity. This approach was implemented partially in a paper manufacturing firm in Iran. Data were gathered by questionnaires and interviews and analyzed interactively with supply chain managers and experts of the firm in order to get valid results. In this case, three first steps of TOC TP i.e. drawing intermediate objective (IO) map, current reality tree (CRT) and conflict remove diagram (CRD) are performed. The results show that these logical diagrams are useful tools to identify supply chain complexity drivers and determine root causes of them.
