Abstract
The Persian Gulf region is one of the strategic and important regions in the world which has always attracted the attention of regional and trans-regional powers. In the contemporary world, the Persian Gulf region and the countries of the Southwest Asia region have been among the most challenging and controversial regions in the world. This region has been the hotbed of geopolitical crises and the site of ideological conflicts and the active hotspot of political and regional crises. In addition to the domestic context, the presence and involvement of trans-regional and global powers in activating and intensifying these challenges and crises have played a very crucial role. Although the macro-structures of the global geopolitical system have overshadowed this space, the powers within the region (the Islamic Republic of Iran and Saudi Arabia) have played a leading role in shaping the geopolitical atmosphere of the current situation, which is based on ideological and geopolitical values. The current study seeks to examine the ideological and geopolitical implications of Iran and Saudi Arabia for the region and the need to adopt a geo-economic strategy to overcome intra-regional geopolitical challenges. The results show that the adoption of a geo-economic strategy by Iran and Saudi Arabia can pave the way for a dialogue of cooperation and convergence and pave the way for entering a new regional geopolitical system for regional development and regionalism.

Abstract
The aim of this study was to identify different population broodstocks of Litopenaeus vannamei and effect of inbreeding and cross-inbreeding on genetic characteristics and inbreeding coefficient of offspring in the next generation. According to origin of broodstocks kept in hatcheries of Bushehr province in the first generation, different populations were identified through microsatellite method from Hybrid, High health and Molokai stocks then, in the next generations genetic characteristics of offspring from their inbreeding and cross-inbreeding were examined. The results showed that the amount of genetic diversity in Molokai and High Health stocks (0.46±0.09 and 0.50±0.07) was more than hybrid stock (0.38±0.06). The inbreeding coefficients of Molokai, High Health and hybrid stocks were 0.14, 0.31 and 0.41, respectively. Due to the low genetic distance between the hybrid and Molokai stocks, after mixing them together Molokai and High Health populations were introduced as the first generation broodstock. In the second generation, despite the high genetic diversity in the offspring of Molokai×High Health (0.47±0.12) and High Health×Molokai (0.39±0.08) than the offspring of Molokai×Molokai (0.19±0.04) and High Health× High Health (0.11±0.03), these values were reduced compared to the first generation. The lowest and highest inbreeding coefficients were related to the offspring of Molokai×High Health (0.268 ±0.18) and Molokai× Molokai (0.853±0.145), respectively. According to the results, it can be said that the lack of knowledge about the genetic characteristics of broodstocks and mating between individual relationships (full and half sib) can reduce genetic characteristics and genetic depression due to increased inbreeding coefficients in next generations.

Abstract
In this study the morphological body variation in five species of Gobiid fish from the intertidal zone of the Persian Gulf and Gulf of Oman have been investigated using 18 morphometric and also three meristic characters. According to the results, 19 of 21 morphological characters of studied species showed a significant statistical difference and among these species, the only two characters "total length" and "pre anal distance" were not statistically different. The results of linear discriminant analysis (LDA) had separated 24.95% of individuals by using morphological characters of the fish body. Data analysis by principal component analysis (PCA) showed that some of morphological characters could be more determinant in species separation in two first axis (PC1 and PC2) which occasionally are possessed in common between two studied species. On the other hand, calculating the Euclidean distance according to studied morphological characters represented that there are small differences in body shape of some species i.e. Boleophthalmus dussumieri and Scartelaos tenuis among other studied species. The results of this study revealed that studying the morphological characters in gobiid fish body shape using univariate and multivariate analysis could make a new vision in these morphological variations of fish body survival.

Abstract
Conflict of interest, which is related to the conflict between public duties and private interests of officials of public institutions, is one of the most important areas of corruption in the structure of the administrative system that may lead people to abuse their position and prefer private interests over Lead public interests; Therefore, designing a comprehensive criminal policy to manage this situation is necessary. The success of managing such a situation depends on focusing on effective measures to prevent its occurrence. Considering the importance of comparative studies in the present study, we have sought to answer the question with a descriptive-analytical method of what approach the countries of the Persian Gulf region have taken towards managing the interests of conflict and preventing corruption. The research findings show that Iran, Bahrain and Qatar have not been able to manage this issue specifically and independently through legislation. On the other hand, other countries have tried to prevent corruption caused by such a situation by formulating legislative criminal policy, which is done both through social prevention measures, especially in the form of ethical codes, and through situational prevention measures such as Depriving persons of public office or deprivation of private interest, the obligation to abstinence from interfering in a matter in which they have a personal stake, and the disclosure of private interests which, by controlling the conflict of interest situation, prevent individuals from abusing.
