In this study at first the researchers have examined the status consumption and then they haveinvestigated the relationship between this consumption habit and social factors (consideringsocial comparison information, susceptibility to interpersonal information influence,susceptibility to interpersonal normative influences).This study has done among the studentsof Islamic Azad University, Tehran Science and Research Branch. The study has alsoanalyzed the findings gathered from 384 samples. To test the hypothesis the researchers haveused the spearman correlation coefficient formula and SPSS software. The results of thisstudy show a positive relationship between "attention to social comparison information,susceptibility to interpersonal normative influence" and "status consumption". There is notany relationship between "susceptibility to interpersonal information influence" and” statusconsumption" is another outcome of this research.

Customer return is one of the important factors in enterprises profitability and in sequence survival in today’s competitive market. The enterprises try to make their customers loyal since this can improve profitability by long-term commitments and decreasing costs of finding new customers. Increasing customer return leads to increase in sales, reduction of costs, higher price acceptability and face-to-face advertising by the customers without any expenditure. So this research investigated and prioritized the effective factors on customers’ loyalty that seemed very important. Since there are a variety of effective factors influencing customer return, in this paper the most effective ones are identified by Fuzzy and prioritized by Fuzzy VIKOR.

The evaluation of performance of banks due to its crucial role in most economic activities
andhealth maintenance of financial markets and economic conditions has always beenconsidered On the other hand, because of the responsibility of DEA models - especially indetecting and determining the efficiency of banks has led to the use of the above-mentionedmodels is extensive.The goal of this article is to offer DEA for evaluating the performance of banks. Efficient andinefficient banks have been identified and finally, for the inefficient banking units thereference model has been introduced. In addition, the relationship between financial ratios andefficiency has been studied. The results show that 9 of the 20 units were efficient and the restwere inefficient. 8 financial ratios are presented: capital adequacy ratio, profitability ratios,management ratio and the asset quality ratio had the most direct relationship withperformance.

The purpose of current research is evaluating cash flow positions of a firm via compositemeasures and metrics such as Days of Sales Outstanding (DSO), Days of InventoryOutstanding (DIO), Days of Payables Outstanding (DPO), Cash Conversion Cycle (CCC),Operating Cash Cycle (OCC) and the effect of these changes on the firm financialperformance. For this purpose, the listed companies in Tehran Stock Exchange have beeninvestigated. In order to examining the relation between cash flow management and firmfinancial performance, linear regression have been utilized. In this research we use eightvariables and this study attempts to address six hypotheses. The samples including 67 firmswhich are studied during 2009-2013 and consists of twenty periods of quarterly data.The findings indicates that there is a meaningful relation between Days of InventoryOutstanding (DIO), Days of Payables Outstanding (DPO), Cash Conversion Cycle (CCC),Operating Cash Cycle (OCC) and financial performance, but there isn’t any meaningfulrelation between Days of Sales Outstanding (DSO) and firm financial performance.

Purchasing has increasingly assumed a pivotal strategic role in supply chain
management.Yet, claims of the strategic role of purchasing have not been fully
subjected to rigoroustheoretical and empirical scrutiny. Extant research has
remained largely anecdotal andtheoretically under-developed. In this paper, the researchers have examined the links amongstrategic purchasing, supply management and firm
performance. They argue that strategicpurchasing can engender sustainable
competitive advantage by enabling firms to: (a) fosterclose working
relationships with a limited number of suppliers (b) promote open communication
among supply chain partners and (c) develop long-term strategic relationship
orientation to achieve mutual gains using structural equation modeling, the researchers have
empirically tested a number of hypotheses based on a sample of 10 companies including
National Iranian South Oil Company. The results provide a robust support for the
linksbetween strategic purchasing, supply management, customer
responsiveness, and financialperformance of the buying firm. Implications for
future research and managerial practice insupply-chain management are also
offered.
