        Financial and credit institutions are threatened by different types of risks. The main objective in thisresearch is to assess and present a proper paradigm to identify, measure, and control financial risks infinancial and credit institutions. The method of research according is applied upon implementation andcorrelation methods, and ex-post facto is accomplished in Bank Mellat. Sampling is intentional, andthe sample volume was determined by the researcher. Required data for this research were collecteddaily from 39 regional offices of Mellat Bank between 2005 and 2007. Structural Equation Modeling(SEM) and Linear Structural Relationships (LISREL) were used to analyze the research data. Thisstudy shows that the impact of loans and investment on liquidity risk, the impact of assets and foreigncurrency debts on foreign currency risk, and the impact of interest sensitive assets and debts volatilityvariant on interest risks are meaningful.

        Measuring the performance of a production system is an important task in management for purposesof control, planning, etc.Lord Kelvin said, “When you can measure what you are speaking about, andexpress it in numbers, you know something about it; but when you cannot measure it, when youcannot express it in numbers, your knowledge is of a meager and unsatisfactory kind.”Hence, management knowledge is a measurable science; if we can’t measure each subject, then wecan’t control then, and management is impossible. We know that the major criterion of performance isproductivity, and we should be able to measure it. Data Envelopment Analysis (DEA) can estimatesystematically the relative efficiencies of an organization. The efficiency of a organization can bebenchmarked using DEA. DEA presents a model for evaluating the performance of a set ofcomparable decision making units (DMUs). In this paper, we develop a new model for calculatingproductivity with data envelopment analysis. Manuscript profile

        The value of a brand lies in its associations with specific mindset and perception of its use in context.In this research, brand social power is considered as the perception that customers have about brandspecifications in the process of making purchasing decisions. Using French and Raven (1959)typology of social influence, five social power bases of brand are identified which correspond to theiroriginal power bases. Assuming the ability of brands to meet various social needs of customers,markets can be segmented, and the target segments can be identified on the basis of those needs.Therefore, referring to Hersey and Blanchard’s situational leadership theory, the readiness levels ofemployees (followers) are generalized to the subjective readiness levels of customers in order toobtain a new indicator for market segmentation, so that, according to each level, we can focus on asingle social power dimension in our market positioning strategies. This research aims to identify theeffect of brand social dimensions based on subjective readiness levels on the purchasing decision ofcustomers. In this survey-descriptive study using random classified sampling, information wasobtained from 382 students using a valid and reliable questionnaire. Structural equation modelingbased on partial least squares was used to analyze data and test the hypotheses. The results suggest thatthe effect of brand social power dimensions based on different levels of customer subjective readinesson purchasing decisions vary. Manuscript profile

        The purpose of this study is to develop a model for strategic parenting in Iran Khodro. The followingobjects are considered:to recognize the specifications of strategic holding-parenting style in the world;A- to determine the existing situation of Iran Khodro Group from a holding–parenting style point ofview; and to present a suitable model for the Iran Khodro strategic parenting style.Most existing research employs a descriptive measurement. Library studying, semi-structured verbalinterviews, and two ascertained questionnaires were used for the present reserach. thirty literaturereview reveals three distinguished characteristics of the strategic holding-parenting style.Semi-structured interviews were done for 13 persons in order to understand the present situation ofIran Khodro Industrial Group and to compare it with the characteristics depicted in the literature. Theresults indicate that six characteristics are considered in Iran Khodro. A first questionnaire wasprepared to understand the conceptual framework of model and the proposed duties; as a result, 16duties were determined and approved by experts. A second questionnaire was prepared to ensure thesuitability of the proposed model; university professors' opinions were polled in the holding office. Toanalyze the data from the questionnaires, descriptive and deductive statistics such as figuresupposition, multi-variable statistical analyzing, abundance calculation, percentage, cause analyzing,and MPL were utilized.

        In the industrial marketing literature, the effects of relationship quality on commercial partners,especially industrial suppliers and buyers, has been investigated from different aspects. Positivevariables affecting the relationship, such as trust, commitment, satisfaction, communications andintention for long-term relationships, as well as negative variables, such as opportunism and conflict,have been considered. By identifying these variables, reinforcing positive variables, decreasing theeffects of negative variables, and developing long-term relationships, a supplier can acquire valuableresults. This research employs descriptive correlation methodology, with a sample of 79 industrialcrane buyer firms; a conceptual plan was examined by structural equation test and PLS software.Research findings indicate that suppliers can attract satisfaction and trust from buyers by maintainingand improving product properties and decreasing opportunism and conflict. Industrial suppliers alsocan enhance relationship quality by focusing on commitment, which reinforces loyalty and intentionsfor long-term relationship. Manuscript profile

        The capital market as a mirror of economy has different functions. One is to improve liquidity in themarket, which provides security for investors. Financial innovations for managing risks are aim toachieve this goal. Accordingly, various kinds of funds have been designed to collect money fromnonprofessional investors in order to reduce risk and make a profit. In this study, we gathered datafrom 13 authorized mutual funds during a 65-week period . To examine the effect of variables on fundreturns, the Fama-MacBeth multilateral regression model was used. The parameters were estimatedusing a mixed panel-data model. Seven fundamental hypotheses were tested; three were disproved;and the rest were confirmed. The results show a meaningful and positive correlation between funds’ex-fluctuations of returns, last period return, age, assets turnover rate, and acquired return. However,no positive or meaningful correlation was found between assets under funds managers’ control, fundfees and charges, rate of injection of new money to funds, and the funds’ acquired returns Manuscript profile

        In order to survey of relationship between social capital and participative management in Gorganۥ sMedicine University, social capital and its components (trust, relational network, and closeness) wereset as the independent variables, and participative management was set as the dependent variable. Theresults show that a direct relationship exists between trustۥ and closeness with participativemanagement. Relational network also has an indirect relationship with participative management bytrust and closeness.Moreover, trust and relational network in organization is about average, andcloseness is low along with participative management assessment.Implement participative management in organizations requires increased trust, relational networks,and closeness Manuscript profile

        One of the most useful algorithms for inventory efficient control is the Fordyce Webster algorithm.This algorithm can solve problems with certainty parameters. In the real world, many parameters, likeinflation, can change inventory costs. This article establishes an algorithm based on fuzzy inventorycosts (e.g. holding costs, ordering costs, and purchase cost). These costs are fuzzy triangular numbers.A numerical example is explained. The results show that the proposed algorithm is very flexible. Manuscript profile
