This paper presents an empirical investigation to determine different methods for increasing employees’ efficiency. The study designs a questionnaire in Likert scale consists of 20 questions, distributes it among 127 randomly selected employees who worked for this organization. Cronbach alphas for all components of the survey were calculated well above 0.70, which validate the overall questionnaire and Kolmogorov-Smirnov test has indicated that the data were normally distributed. Using t-student test, the study has confirmed three approaches for increasing efficiency including methods to improve employee management and organizational structures, methods to improve financial and moral encouragement system and methods for improvement of staff performance efficiency assessment.

In highly competitive markets, building brand equity has become one of the first priorities for many organizations as it brings several benefits and reputation for them. Past researches have acknowledged that consumers look for brands which provide them with differential values through innovative product and service features. However, despite the importance of product innovation in determining an organization’s success, very limited studies have intended to examine its effect on brand equity. In the present study, we aim to examine the effect of product innovation on brand equity in Malaysian automotive market. The data were collected from 287 passenger cars owners through self-administered questionnaire at several shopping malls in northern Malaysia. The findings revealed that product innovation had significant positive effect on overall brand equity and its dimensions namely; brand awareness, brand loyalty, brand image, and brand leadership. Based on the results of this study, several implications are discussed to enlighten our knowledge on important innovation activities that could develop favorable brand equity. Finally, limitations and future research suggestions are highlighted to gain better insights on brand equity development.

The present study seeks to examine the stock-selection performance of the sample open-ended equity mutual fund schemes of Birla Sun Life Mutual Fund Company based on traditional and conditional performance measures. It is generally expected that inclusion of some relevant predetermined public information variables in the conditional CAPM provides better performance estimates as compared to the traditional measures. The study reports that after inclusion of conditioning public information variables, the selectivity performances of the schemes have dramatically improved relative to the traditional measure and also found that conditional measure is superior to traditional measure in statistical test.

This paper presents an empirical investigation to determine factors influencing on loan repayment in one of Iranian banks named Sepah Bank over the period 2012-2013. The study selects a sample of 290 bank’s customers who received loans and, using logistic regression technique, tries to find whether or not qualitative as well as quantitative characteristics of loan receivers influence on repayment of loans. The results indicate that history of outstanding debt as well as customers’ past experiences with banks had meaningful relationships with having bad credit and non-payment of loans. In our survey, having a bad credit in the past had positive relationship with non-payment of loans but long-term customers had negative relationship with non-payment of loans. In addition, working capital turnover ratio, cash ratio, total liabilities, current assets and loan value had significant impact on non-repayment of the loan facilities.

This paper presents an empirical investigation to study the relationship between product market competition and voluntary disclosure among 124 selected firms listed on Tehran Stock Exchange over the period 2004-2013. The study uses Herfindahl–Hirschman Index (HHI) and Lerner (LLIA) index to measure competition in terms of capacity and price, respectively. In addition, the study uses the questionnaire developed by Botosan (1997) [Botosan, C. A. (1997). Disclosure level and the cost of equity capital. Accounting Review, 72(3), 323-349.] to measure voluntary disclosure. Using linear regression technique, the study has determined that there was a meaningful, direct and positive relationship between voluntary disclosure and competition in terms of price (LLIA). In addition, the results indicate that there was a meaningful and reverse relationship between voluntary disclosure and competition in terms of capacity (HHI).

This study explains the components of ethical behavior and their impacts on life insurance companies in province of Mazandaran, Iran. There were 367 insurance representatives and the study selects a sample of 187 ones based on Cochran formula and 2 questionnaires were distributed among them. The first questionnaire, unethical behavior, includes 8 items including Bribery, Cheating, Deception, Interact with colleagues, Act as social behavior, Uncommitted to firm and Irresponsibility. In addition, the questionnaire of brand equity contains three components of Awareness, Perceived quality and Loyalty. Using structural equation modeling, the study has determined that the effects of cheating and deception on unethical behaviors were not confirmed but the effects of other factors, bribery, interact with colleagues, act as social behavior, uncommitted to firm and irresponsibility on unethical behavior were confirmed. In addition, three components of Awareness, Perceived quality and Loyalty had positive relationship with brand equity.

This paper studies the relationship between principals’ reward power and their conflict management styles. The five conflict management styles that we use in this study are based on Thomas-Kilmann Conflict Mode Instrument and include accommodating, avoiding, collaborating, competing, and compromising styles. This study can be classified as a regression analysis and is a descriptive study. Our statistical society for this research included all principals of high schools located in the city of Birjand. The results indicated that there was a significant relationship between principal’s reward power and accommodating conflict management style. The results also revealed that there was no significant relationship between principals’ reward power and the other four conflict management styles.

This paper aims to provide proper policies for inventory under uncertain conditions by comparing different inventory policies. To review the efficiency of these algorithms it is necessary to specify the area in which each of them is applied. Therefore, each of the models has been reviewed under different forms of retailing and they are ranked in terms of their expenses. According to the high values of inventories and their impacts on the costs of the companies, the ranking of various models using the simulation annealing algorithm are presented, which indicates that the proposed model of this paper could perform better than other alternative ones. The results also indicate that the suggested algorithm could save from 4 to 29 percent on costs of inventories.

The single machine scheduling problem aims at obtaining the best sequence for a set of jobs in a manufacturing system with a single machine. In this paper, we optimize rewards in single machine scheduling in rewards-driven systems such that total reward is maximized while the constraints contains of limitation in total rewards for earliness and learning, independent of earliness and learning and etc. are satisfied. In mentioned systems as for earliness and learning the bonus is awarded to operators, we consider only rewards in mentioned systems and it will not be penalized under any circumstances. Our objective is to optimize total rewards in mentioned system by taking the rewards in the form of quadratic for both learning and earliness. The recently-developed sequential quadratic programming (SQP), is used by solve the problem. Results show that SQP had satisfactory performance in terms of optimum solutions, number of iterations, infeasibility and optimality error. Finally, a sensitivity analysis is performed on the change rate of the objective function obtained based on the change rate of the “amount of earliness for jobs (Ei parameter)”.
