Nowadays, financial markets in Iran have attracted the attention of many managers, investors and financial policymakers. Therefore, in order to make the optimal decision and reduce the risks in such a market, it is important to identify and analyze the network behavior of the financial markets at different times to obtain the optimal decision. The current study aims to answer the following research question; how is it possible to use the minimum spanning tree and hierarchical clustering in the network analysis of the Tehran Stock Exchange? The period examined was 2013 to 2018. The population consisted of all the companies accepted in Tehran Stock Exchange. The sampling was selected purposefully and contained the companies which had at least one trading day in the time span from the beginning of 2013 to the end of 2018. The stock of the investigated companies was considered as the vertexes of one graph and the coherent information criterion was considered as the weight of the edge. First, the minimum spanning tree of the graph was calculated. The results revealed that the stocks of DarooAbuReihan, DarooPakhsh and Alborzdaroo had a high influence on directing the prices of the other stocks. Furthermore, the results of hierarchical clustering classified the stocks of the companies into 8 clusters. This study presents a viewpoint about the modern method designed for the analysis of complex financial networks. Moreover, the study offers an analysis of Iran's stock market structure which can be the center of finance researchers and analysts' attention.

HélèneCixous, the renowned contemporary philosopher and feminist, provides such a heretic account of femininity which transcends the feminist social or political movements. She believes that “the female” can create a new identity for itself, when keeps its distance from the masculine symbolic order. Of course, this has nothing to do with the absence of women in the cultural realm, rather the problem is that if the female aspects of human being are not to be eliminated, a new ontology is required to sustain it in a pointlessness situation, so that it can always resist the conventional perceptual patterns. In other words, the female can only make its identity and the nature of rationality dynamic, when it injects the strangeness in the masculine order. This means keeping a position on the margins of history, while also infusing the feminine energies into the symbolic body. In this research, we try to show that for Cixous, emergence of the new is dependent both on some kind of feminine otherness and the marginality. This can be realized by various dismantling tools such as women’s writing and polyphonic identities. Finally we make it clear that through the female otherness or being on the margins, the feminine can provide a way of thinking about those realities which have not been thought up so far in the symbolic rationality, or have always been rejected as the unthinkable.
