The Impact of Rawls and MacIntyre Theory of Justice on National Cohesion in Multicultural Societies

Abstract Today, many countries have differences ethnic, subcultures, communities and religions. Managing and making policy in this society is more difficult than en bloc societies. Therefore one of more important of their problems is making just policies, which create and preserve national cohesion. To achieving this purpose, their governments try to use a justice theory, which can apply justice among people and preserve national cohesion. There is several justice theories that may help to these kinds of societies, and each society based on its own positions select and perform one of them. Among different theory of justice, this essay studies Rawls and Macintyre theory of justice, because They play a huge role in shaping political philosophy, and also they represent two major contemporary political streams like liberalism and communitarians. The main question that this essay tries to follow is which theories of justice could be useful in multicultural society and cause to create national cohesion. This essay use descriptive and analysis method

Interaction of fish density and background color effects on growth performance, proximate body composition and skin color of common carp, Cyprinus carpio

This study was carried out to evaluate the combined effects of three stocking densities and two tank colors on growth, body composition and skin coloration of common carp (1.41±0.05 g). Fish with low (LD: 20 specimens/tank or 0.70 g/L), medium (MD: 40 specimens/tank or 1.41 g/L) and high (HD: 80 specimens/tank or 2.82 g/L) densities were reared in two tank colors (black and white) for 45 days. At the end of the experiment, density recorded 2.45 g/L and 7.00 g/L at low and high densities treatments, respectively. The final weight and specific growth rate of the fish at LD treatment were significantly higher than those of MD and HD treatments. The highest weight (4.90±0.44 g) and the lowest feed conversion ratio (1.21±0.13) were obtained for the LD fish treatment reared in the black tanks. Rearing density has a significant effect on the fish body total protein content, but the tank color had no effects on this factor. The fish body lipid content in the white tanks and high density was significantly higher than other treatments. Significant interactions between tank color and rearing density were observed for the fish body protein, fiber and dry matter. The fish skin color was considered by three factors: L*, a* and b*. The results showed that black color had a negative effect on the fish skin color indices. Brightness (L*) and yellowness (b*) values of the fish skin in the white tanks were higher than those of the black tanks. In the present study, tank color and rearing density significantly affected growth and feed performance of common carp, while no combined interaction was found between the two factors examined

Explaining the Impact of Globalization on the Level of Political Corruption in Iran

IntroductionPolitical corruption is one of the crucial concerns in today’s political landscape that has captured the attention of researchers. Political corruption refers to the breach of public norms by those in political power, either to further personal interests or to protect group interests. It entails the manipulation of political institutions and internal regulations, thereby impacting government bodies and the overall political system. Consequently, political corruption is often anticipated to result in institutional deterioration. However, since the 1980s, globalization has influenced the way through which categories of modern politics, including political corruption, are addressed. In the context of globalization, the examination of political corruption transcends the confines of the nation–state and should be viewed as a global concern.Literature ReviewA review of primary studies concerning the impact of globalization on political corruption reveals a spectrum of pessimistic and optimistic opinions among scholars. Optimists argue that globalization diminishes political corruption, while pessimists contend that it, in fact, increases political corruption. However, recent research indicates that the discrepancy between these viewpoints stems from their differing understandings of the relationship between globalization and political corruption. By adhering to a linear approach, both groups attempt to find the relationship between these variables, and consequently prescribe or discourage further engagement with globalization to exploit opportunities and avoid threats. To resolve this discrepancy, new studies, adopting a non-linear approach, posit that social and political globalization serves as a significant precursor to corruption. Economic globalization is perceived as both a prelude to and a consequence of varying levels of corruption.Materials and MethodsAs a quantitative research, the present study employed regression analysis as a highly practical quantitative method. Specifically, it utilized polynomial regression, which is supported by recent studies as well as by the secondary data sourced from the V-Dem Institute and the KOF Swiss Economic Institute.Results and Discussion According to the regression analysis, the normative nature of political corruption necessitates a redefinition of public and private interests at both the societal and governmental elite levels if the aim is to enhance the social dimension of globalization. The coefficient of the political dimension indicated that increased globalization can lead to a reduction in political corruption as global pressures compel the country to undertake structural and institutional reforms, including safeguarding property rights, enhancing transparency in decision-making processes, and improving the quality of public services. However, the results showed that there is no linear relationship between economic dimension of globalization and political corruption. Instead, the economic dimension influences the impact of other dimensions on political corruption in a non-linear, curved manner. As this dimension increases, political corruption decreases up to a certain point, but beyond that threshold, corruption levels begin to rise.One of the ideals and goals that emerged during the formation of the Islamic Revolution in Iran was the fight against the political corruption that had been rampant during the Pahlavi era, which required a revolutionary change as the only means to eliminate corruption. However, following the success of the Revolution, the government of the Islamic Republic of Iran inherited a political, governance, and administrative system that later fell into the depths of various forms of corruption. The present research aimed to address a fundamental question: What is the impact of Iran’s engagement with globalization on the level of political corruption in the country? The necessity of conducting such studies arises from the importance of understanding the effect of globalization on various political issues with the ultimate aim of leveraging the benefits and avoiding the threats. Considering Iran’s economic structure, the system of international sanctions against Iran, and the normative nature of political corruption, it is expected that the various dimensions of globalization may have a detrimental impact on political corruption in Iran. Conclusion In conclusion, given the concurrent influence of different dimensions of globalization on political issues, policymakers are recommended to follow a non-linear approach to leverage the opportunities and avoid the threats of globalization

Evaluation of fatty acids and the muscle quality in common carp (Cyprinus carpio) fingerlings under aquaponics culture system

To evaluate the flesh quality of fingerling common carp reared in aquaponics culture system, fish with cucumber and lettuce was reared under the aquaponics system for 60 days with three treatments including cultivation of common carp without plants (T0), an aquaponics system for culturing common carp with lettuce (TL), and cucumber (TC) each with three replications. For the meat quality evaluation of reared fish, at the final rearing period after harvesting fish, chemical composition, fatty acid profile, color, texture profile analysis, and sensory assessment were determined. The result showed that protein and lipid content in T0 and TC were significantly higher than in TL (P<0.05). Most of the sum monounsaturated fatty acids (∑MUFA) and polyunsaturated fatty acids (∑PUFA) were recorded in TC and T0, respectively. Lipid quality base on the atherogenic (AI) and thrombogenic (TI) indices in TL was higher than in TC. According to color indices, fish skin in T0 and TL exhibited similar lightness and transparency, higher than in Tc. The color of fish muscle in TC displayed redness higher than in the other treatments. In case of texture profile analysis, springiness in TC was significantly higher compare to the other treatments. In case of sensory assessment, the score of odor attribute in TC was significantly lower compare to the other treatments. In conclusion, the muscle quality in the fish reared under aquaponics culture system was more acceptable in comparison with that in T0 (common carp reared without the plants) and in case of fish reared under aquaponics system, those reared with cucumber revealed better quality than the lettuce

Effects of Yucca schidigera extract on the growth performance, feed efficiency, body composition of common carp (Cyprinus carpio, Linnaeus 1758) and culture water quality

One of the important goals in the aquaculture industry is to increase fish production with the least stress from ammonia secretion. Yucca plant (Yucca schidigera) was composed of steroidal saponins, polysaccharides, and polyphenols, which have increase the intestinal flora activity to improving the digestive process, also great absorption capacity for harmful volatile compounds, such as ammonia and hydrogen sulfide. Therefore, the aim of this study was to evaluate the effects of different Yucca schidigera extract levels on the Cyprinus carpio growth, feed performance, body composition and culture water quality for 60 days. Experimental treatments were designed which include: T1 (control without extracts), T2, T3 and T4 treatments (containing 0.5, 1 and 1.5% Yucca extract respectively). In a completely randomized design, 360 Common carp fish with weight of 2.40±0.04 g and length of 5.47±0.05 cm were reared in twelve 40-L plastic tanks. Different levels of extract were sprayed on commercial food and consumed at 4 times daily. There was significantly higher final body weights in T4 (p<0.05) compared with control (T1) and other experimental treatments (T2 and T3). Similarly, significantly better (p<0.05) feed conversion ratio (FCR), 2.01±0.37 and protein efficiency ratio (PER), 0.17±0.01 was noticed in T4 compared to control (FCR 2.71±0.31 and PER 0.14±0.01). The biochemical composition of carcass had a significant difference between treatments (p<0.05). The body chemical composition analysis showed that the low levels of crude protein and the high levels of crude lipids in T4 treatment were 62.87±2.63% and 26.29±1.55%, respectively. The physical and chemical parameters were within the recommended range for C.carpio. The experiment treatments had the lowest amount of ammonia and the highest amount of nitrate compared to the control treatment in culture water. The results of this experiment showed that the use of Yucca extract can improve the growth, feed performance, body composition and the water quality of the common carp culture system

The modalities of Iranian soft power: from cultural diplomacy to soft war

Through exploring Iran's public diplomacy at the international level, this article demonstrates how the Islamic Republic's motives should not only be contextualised within the oft-sensationalised, material or ‘hard’ aspects of its foreign policy, but also within the desire to project its cultural reach through ‘softer’ means. Iran's utilisation of culturally defined foreign policy objectives and actions demonstrates its understanding of soft power's potentialities. This article explores the ways in which Iran's public diplomacy is used to promote its soft power and craft its, at times, shifting image on the world stage

Assessment of essential elements in the wild Beluga Sturgeon (Huso huso) caviar from Caspian Sea

In this study, the concentration of Calcium (Ca), Cobalt (Co), Chromium (Cr), Copper (Cu), Iron (Fe), Potassium (K), Magnesium (Mg), Manganese (Mn), Selenium (Se) and Zinc (Zn) as essential metals, were determined in caviar of wild beluga sturgeon caught from the Caspian Sea in March 2012. Potassium (4885.51± 17.81 µg g-1) and Magnesium (346.61± 6.6 µg g-1) had the highest concentration and Cobalt and Manganese levels were less than 0.01 mg kg-1 wet weight. The mean concentration of Copper and Zinc in the caviar samples were under the permissible limits proposed by the UK’s Ministry of Agriculture, Fisheries and Foods. The caviar maximum allowable daily consumption rate was calculated. However, the health risks from caviar consumption are uncertain because the amount of caviar consumed by heavy users is not known

Concept-based Instruction and Teaching English Tense and Aspect to Iranian School Learners

The present study examines the role of Gal’perin’s Concept-based Instruction (CBI) as a pedagogical approach in teaching cognitive grammar-based (CG-based) concepts of tense and aspect to EFL students. Following the sociocultural theory of L2 Acquisition (SCT), arming L2 learners with scientific concepts can lead to L2 development by deepening their understanding and raising awareness of L2 structures. To this end, over the course of eight weeks 28 third grade middle school students (14 years old) received the concepts in the CBI framework and 30 third grade middle school students received a traditional type of instruction. There were three sets of data including definition of the concepts of tense and aspect before and after CBI, concept verbalization data during CBI, written discourse performance plus responses to a set of grammatical questions before and after CBI. It was found that although both groups improved significantly after receiving the instruction, the students who received CBI performed significantly better than those in the traditional group. The students who received CBI also produced a significant definition of the concepts and their written discourse performance and responses to the grammatical questions improved after CBI. The result provides insight into the application of scientific concepts in L2 instruction

Effects of Bacillus probiotic enzyme extract on growth and carcass biochemical composition of rainbow trout (Oncorhynchus mykiss) larvae

The present study was done to evaluate the effects of enzyme extract, produced by five species of probiotics Bacillus on growth and carcass biochemical composition of rainbow trout (Oncorhynchus mykiss) larvae with initial body weight of 0.583 ± 0.197 g (mean ± SD). The enzyme extract was produced by Bacillus probiotics in broth media with concentrations of 1 × 10^6, 1 × 10^7 and 1 × 10^8 CFU/100g and then it was added into the feed of rainbow trout larvae respectively. The results of larval biometry at the end of the study showed that the use of enzyme extract with the highest Bacillus concentration (1×10^8 CFU/100g) in T3 (20.02 ±3.77 g) significantly increased the growth (P<0.05). Also other growth parameters as specific growth rate and average daily growth showed significant differences (P<0.05). The study of carcass biochemical composition according to AOAC (1990) standard showed that T1 and T3 had the highest crude protein content and control had the lowest crude protein content. Also the experimental treatments showed the highest survival rate in comparison with the control (P<0.05). The results of this study showed that enzyme extract of Bacillus probiotic improved the growth performance and feed efficiency in rainbow trout larvae and also increased the survival rate
