In this paper, we present an empirical investigation on various factors affecting ADSL service selection in city of Tehran, Iran. The proposed model of this paper uses a standard questionnaire and distributes it among randomly selected customers who have some experiences on internet based ADSL products. The study implements factor analysis as well as weighted regression technique to perform the study. There are eight hypotheses associated with the proposed study of this paper, which indicates the effects of product marketing, place and time of marketing mix, process-marketing mix, productivity and quality of marketing mix, people, promotion and education and physical evidence on customer choice. The results of factor analysis have confirmed the impacts of the first four factors but the effects of the other factor were not confirmed. In other words, the results of the survey have indicated that product marketing, place and time of marketing mix, process-marketing mix and productivity and quality of marketing mix influence customer choice. However, the other four components including people, promotion, price and physical evidence do not play essential role on customer choice.

This paper performs a social work study on the effect of spiritual intelligence and psychological capital on sense of vitality among elementary school teachers in two regions of city of Esfahan, Iran. The proposed study uses three standard questionnaires of psychological capital questionnaire (PCQ), Spiritual Intelligence Self-Report Inventory (SISRI-24) and sense of vitality and distributes them among 263 teachers selected, randomly. The results of the survey have been analyzed using Pearson correlation as well as stepwise regression techniques. The results of the Pearson correlation tests have shown that the components of psychological capital questionnaire and spiritual intelligence have meaningful relationship with sense of vitality (P & LT; 0.01). The survey have also confirmed that psychological capital and spiritual intelligence have meaningful effects on teachers’ personal characteristics.

This paper studies the effective of family life education (FLE) on marital status among women attending in Isfahan counseling centers. The methodology of this research was quasi experimental with pre-test and post-test design and control group. Statistical populations were women attending in Isfahan city counseling centers. For selecting statistical sample, 30 women from women attending in counseling centers were selected as volunteers and randomly distributed between experimental and control groups. The main hypothesis of this research states that FLE increases marital satisfaction and their subscales in women. In this study, the dependent variable was marital-satisfaction and the independent variable was family life education conducted to case group in 10 sessions. The results of this survey show that the FLE improved marital satisfaction (p & LT; 0.01) and it was effective on the subscales (p & LT; 0.01).

Knowledge plays an essential role on creating value added business units in today’s competitive environment. In this paper, we perform a study to investigate the relationship between knowledge management and organization culture in an Iranian PVC industry. The proposed study selects a sample of 65 people and distributes a questionnaire among them. The study investigates the relationship between knowledge management and four organizational cultures’ components including mission, consistency, involvement and adaptability. Using Denison model and implementation of Pearson correlation ratio as well as stepwise regression techniques, we analyze four hypotheses of the survey. The results of the study confirm that there are strong relationships between knowledge management from one side and mission, consistency, involvement and adaptability.

This paper investigates the impact of ethical climate on turnover intentions and organizational performance based on the implementation of various techniques. The interview method was used to identify the factors of input and output. Required data were collected to measure performance of firms based on some documents. The survey method was used to study the ethical climate and turnover intentions. The impact of ethical climate on turnover intentions and organizational performance was evaluated. The information was analyzed based on different software packages including Deap2.1, SPSS.18 (PASW) and Lisrel 8.1. The preliminary results indicate that organizational ethical climate positively impacts on sales representative performance and negatively influences on turnover Intentions. The highest positively correlations were between sales practices and organizational performance (r=0.48) and the highest negatively correlations were between sales practices and turnover intentions(r=-0.72).

Developing economy needs appropriate infrastructure in different areas including electronic banking. This paper presents an empirical investigation on important factors influencing electronic banking for developing exports in Iran. The proposed study of this paper designs a questionnaire and distributes it among 200 regular customers who use banking services of various banks in city of Tehran, Iran. Cronbach alpha has been calculated as 0.752 and there are five factors including internet infrastructure, advanced services, usability and information design. The most important sub-criteria include building required culture, customer awareness, the role of government, internet knowledge and compatibility with internet technology.

An increase on competition industry from one side and the need for customer retention on the other side in banking industry create necessary motivation to learn more about customer behavior. This paper investigated the relationship between seven perspectives of banking services and customers’ attitude towards changing behavior. The seven perspectives included how bank employees’ treat customers, service prices, how to promote and market synergies, place and time to serve customers, products, equipment and process. The proposed study was implemented in two Iranian banks called Mellat and Tejarat in city of Tehran, Iran. The results indicated that all components except one case, which was “how to promote and market synergies” had meaningful and negative relationship with customer behavior.

This paper presents a logistic regression model to measure risk management of receivable accounts on some selected firms from drug industry listed on Tehran Stock Exchange. The proposed study of this paper considers the effects of different variables such as current ratio, quick ratio, working capital on total assets and cash flow on economic value added. We gather the necessary information of 29 firms over the period 2006-2011. The results of our survey indicate that the proposed model of this paper is capable of forecasting high profit firms with a probability of 87.5%, 58.62% is the likelihood of predicting less profitable firms and on average, the firm could forecast profitable firms for 75.54%, successfully.

Many firms try to optimize their supply and production levels separately, but this method could limit influence profitability, negatively. Thus, it is becoming more important to analyze these two levels, simultaneously. In this paper, an integrated supply-production planning is considered, simultaneously. We develop a mathematical model, which calculates the optimal inventory lot sizing for each supplier and minimizes the total cost associated with the process of procuring raw material, transferring and holding raw materials and manufacturing. The problem is formulated as a nonlinear programming and heuristic genetic algorithm (GA) method is developed to solve the resulted problem. We examine the performance of the proposed model for a case study conducted in Iran. Experimental results show that such a model can reduce the costs of the case study, substantially.

Organizational structure is one of the most important components of any firm and it plays essential role on building successful business units. Organizational structure in cooperative organizations may influence productivity of such organizations, significantly. In this paper, we consider the relationship between various components including formality, complexity, concentration on performance measurement in cooperative organizations in province of Qom, Iran. The study selects 280 firms out of 1069 cooperative organizations and using Pearson correlation test examines different hypotheses. Based on the results of our survey, formality and concentration have positive impacts on the success of cooperative organizations but the impact of complexity on performance of organization is not confirmed.
