At the present time that our country is passing through a critical period, the role of the administrative, industrial and educational organizations is inevitable in the economic operation and development of the country. But the fact whether all of them have been successful in making an effort to obtain the given aims is really questionable, because some of them seem to have performed a lot better than the others. Viewing the success of some of these organizations, we can find out about some common and key factors which have played important roles in their efficient performance. An important factor is the existing powerful and overruling culture in which these organizations operate. Certainly, getting to know such factors and supporting them would be a useful step in leading these organizations to achieve their ideal goals successfully. In this Article, first a theoretical analysis of culture and organizational culture is presented, then labor productivity and finally the existing theories concerning the relationship between organizational culture and labor productivity are explained. Also, in this investigation, using variance test analysis, the rank of Management Colleges of such academic institutions like Higher Education Confederate of Ghom, Tehran University, Allameh - Tabatabaei University and Shahid Beheshti University have been determined on the basis of the impact of organizational culture on the rate of productivity. By applying the correlation coefficient of Spearman, the relation of organizational culture with productivity of colleges has been analyzed with regard to the criteria explained for productivity. Finally, using Friedman’s test the criteria and characteristics of organizational culture have been ranked.

This research explores power relations in Touba and the Meaning of Night, focusing on the gender issue and gender representation in the novel. Studying modal structures and modality is one of the tools provided by Halliday’s social linguistics for examining texts and revealing their ideological functions. Focusing on the role of modality in the production of texts and reproduction of power and gender relations, we study modality in this novel with an analytic-descriptive method. The novel offers a seventy-year-old historical perspective on Iranian women. However, in the course of this seemingly progressive historical movement, Touba, the heroine of the novel, not only does not achieve her ends but also, quite on the contrary, shows signs of regression. In the beginning of the novel, Touba is a self-assured woman who talks and acts decisively, but toward the ending of the novel she turns into someone without certainty or any kind of conviction. Indeed, Touba’s modal structures evolve from external certitude and determination to internal doubt and hesitation. In the end, Touba’s internal evolution and spiritual barrenness are closely related to more general social discursive relations and functions during the Qajar and First Pahlavi dynasties, especially those convictions that prevent women from thinking, speaking, and participating in external practices in the social scene.

The aim of this study was to investigate the antioxidant and antibacterial effect of green bell pepper essential oil for qualitative comparison of silver carp sausage with meat sausage during refrigeration and also to replace some of the nitrite sodium (NaNO2) used in meat products. The essential oil was extracted from green bell pepper by the Clevenger method and ascorbic acid, phenolic compounds, free radical scavenging (DPPH) tests were performed to determine the antioxidant and antibacterial power. The essential oil extracted in three concentrations of 0, 2, and 4% was added to sausage samples prepared from silver carp and meat. Samples were stored at 4 ° C for 30 days. Chemical tests (pH, TBA, and TVN) and microbial evaluation (TMC, PTC, coliform, and mold and yeast) were performed at intervals of 5 days for 30 days in 3 replications. Results of pH, TBA (mg MDA / Kg fat), TVN (mg N / 100g Flesh), TMC, Pseudomonas, coliform and mold and yeast (CFU/g) on ​​day 30 for control treatment of fish sausage (minimum shelf-life) were 7.63, 3.4, 45.3, 11.6, 11, 2.5, and 1.5, respectively, and meat sausage treatment containing 4% of green bell pepper essential oil (maximum shelf -life) were 7.35, 1.86, 34.5, 5.3, 4.9, 0.62, 0, respectively. The results showed that 4% green bell pepper essential oil can be used as a suitable natural preservative in meat and fish sausages.
