Abstract
The aim of study it was carried out survey investigation of consumer attitudes toward organic agriculture. The study was a kind of applied and descriptive –correlational method. The research population was consumers of agricultural products in Alborz Province. Sample size was determine by Cochran's formula (n= 250). Proportional stratified random sampling method was used. Data was collected through an instrument that developed by researcher. Validity estimated by a panel of experts in University and Agriculture experts’ of jihad-e- keshavarzi department of Karaj city. Reliability was conducted by a Pilot test and Cronbach’s alpha coefficient assumed (0/75) which show its suit for research conduct. Data analysis was performed using SPSS software package. Research findings show that there is a significant difference between responces in diploma and graduate & post graduted level at the 0.05 level. Also there is positive relation between consume obstacle and factors affecting to use of organice agriculture with responcendents attitude.

Abstract
The aim of this study was to analyze the components of Consumer behavior toward food waste. The study was a kind of applied and descriptive – correlational method. The research population was consumers of food products in Tehran city. Sample size was determine by Kerjice and Morgan table (n= 384). Proportional stratified random sampling method was used. The research instrument was a researcher-made questionnaire. Validity of the questionnaire was confirmed by a panel of expert in Agricultural Extension and Education Department, Tarbiat Modarres University. Reliability was conducted by a Pilot test and Cronbach’s alpha coefficient assumed (0/86) which show its suit for research conduct.

Abstract Selecting a portfolio has always been a significant issue in Financial Management. The models presented for selecting the best portfolio have some deficiencies and after some time, their deficiencies would be revealed and they will be replaced by some other models. One of the problems with those models is neglecting the multifaceted indices and dimensions for final evaluation of portfolio, and these efficiencies will bring the validity of the evaluation results under question. In order to remove these efficiencies, one can use DEA (Data Envelopment Analysis) technique which is one of the MCDM (Multi-Criteria Decision Making) techniques. In this paper, two models have been presented; one finds the most efficient portfolio and the other one finds the most inefficient. In this paper, 95 companies now present in Tehran Stock Market have been investigated. The results demonstrate that out of those 95 companies, seven companies are efficient and 8 companies are utterly inefficient.

Abstract
Most of the time, Groups/Communities are involved in negotiations and disputations due to their various interests. They are always trying to pursuit their aspiration to embrace changes and influence on events. Although sometimes these groups are not completely opposed to each other and their intention is just to get the desired results, almost always their conditions are in contrast with each other. These conflicts prevent negotiators from approaching desired acceptable solutions. For improving the negotiations, resolving the conflicts and reaching satisfactory decisions, Drama theory is applied. This theory is based on game theory. In this paper, Iran Nuclear talks with 5+1 Group will be discussed as an applicable case for drama theory.

Abstract
The aim of this paper was to evaluate the impacts of International Corporate Entrepreneurship (ICE) on general performance in Halal Food Industry, with moderating part of global environmental hostility. Our data comprised of 250 firms working in Halal Food Industry in Iran and they were studied utilizing the structural equation modeling. According to the results, the firms exploit ICE activities by accomplishing higher general performance in addition to promoting export and financial performance. The results underscore the significance of ICE for organizational achievement, both in general and in foreign markets. Also, the results suggest that the perceived nature of its environmental condition, especially hostility, will affect the link between ICE and performance fundamentally. This study explored the relationship between ICE and firm performance along with the role of hostility at the international environment in this relationship. The findings of this study help bridge the gap in the literature by assessing the impact of ICE on an organization's general performance with the hostilities at the international scale playing a moderating role in this regard. This paper makes huge contribution to the current works by exploring the connection between ICE, firm performance, and global environmental hostility.

Abstract
The present research was conducted to evaluate the efficacy of six different entomopathogenic fungi and bacterial formulation against the third-instar grubs of a subterranean biennial white grub species, Lepidiota mansueta. All treatments proved effective, recording over 55% mortality of white grubs compared to the untreated control at 30 Days After Treatment (DAT). However, the highest cumulative mortality (76%) was observed in Beauveria bassiana (KR855715), followed by 72% in Beauveria brongniartii (BbUASB16) and 70.67% in Bio-Bt (Bacillus thuringiensis) treated grubs. Metarhizium anisopliae-based formulation (Bio-Meta) exhibited the lowest mortality rate (58.67%). Overall, B. bassiana (KR855715) and B. brongniartii (BbUASB16) demonstrated higher virulence towards L. mansueta grubs, indicating their potential as biological control agents against these pests. The LT50 values varied from 12.15 to 23.05 days when L. mansueta grubs were treated with different entomopathogenic treatments. In case of KR855715 strain, the LT50 value recorded was 12.15 days (FL 11.15-13.11), which was the lowest, and in Bio-Meta, the LT50 recorded was 23.05 days (FL 19.24-30.33), which was the highest. In conclusion, as chemical pesticides are not always the best option for controlling scarabs, entomopathogenic fungus can be incorporated into Integrated Pest Management (IPM) strategies as biological control agents. This is especially useful for managing populations of early-season white grubs. Therefore, to keep the pest population in an environmentally balanced level and to provide long-term control for the grubs, these tested entomopathogens may serve as possible biocontrol agents against L. mansueta grubs.
