Among the challenges of language acquisition, developing writing proficiency is widely acknowledged as particularly demanding. Learners must not only select appropriate vocabulary but also use it effectively within a specific context. However, the emphasis on writing skill development should not solely lie in memorizing grammatical rules. Rather, grammar should serve as a tool to facilitate clear and effective communication of ideas. Consequently, prioritizing and strategically selecting essential grammar rules for instruction can significantly enhance and expedite the acquisition of writing skills. This research employs a descriptive-analytical method and utilizes a questionnaire to investigate the potential effects of streamlining Arabic grammar instruction on facilitating and accelerating the development of writing skills in Arabic among Persian undergraduate students majoring in Arabic Language and Literature. To achieve this objective, the study employed a researcher-designed questionnaire distributed among a sample of 16 Arabic language teachers and experts. This instrument aimed to identify the relative importance of Arabic grammar components across three proficiency levels: beginner, intermediate, and advanced. Informed by expert opinion, the research proposes a tiered approach to Arabic grammar instruction. At the beginner level, priority is given to mastering structural order and interrogative particles. The intermediate level focuses on relative nouns, causative constructions, and the mood system. Finally, advanced learners concentrate on verbal mode and aspects. Additionally, the findings highlight the experts' emphasis on introducing similar Arabic and Persian grammar rules in the early stages of education, and Arabic-specific rules at higher levels.

Critical Thinking (CT) which has been defined as the employment of cognitive skills or strategies for obtaining sound conclusions (Halpern, 2013) has been the subject of different Second Language (L2) studies at national and international levels. The aim of the present study was to provide a meta-analysis on the (quasi) experimental studies of critical thinking in second language education in Iran. To this end, from a total of 168 studies published between 2011 and 2020, 24 studies were selected based on the inclusion-exclusion criteria. The included studies were coded to calculate the mean effect size of the studies. The results show that 1) L2 teaching was positively effective for the CT development in Iran; 2) the most beneficial aspects of L2 teaching on CT promotion were related to teaching L2 speaking and L2 rhetorical strategies; 3) concerning L2 proficiency level, L2 instruction was most advantageous for advanced students’ CT developments; 4) regarding the age groups, L2 teaching contributed the most growth in CT levels for learners in the age group of 10-14 years, and 5) L2 teaching was most effective for the undergraduate students compared to other educational levels. The findings can be beneficial for pursuing the next moves in L2 research, education, and planning educational policies in Iran.

This paper deals with the object agreement phenomenon in the transcriptions written in Middle Persian language. This study is a descriptive study and is classified as a library research. The collected data from transcriptions in Middle Persian language namely as Ardā-Virāf-nāmeh, Bundahishn, Dānāk u Mainyo-ī Khard, Dēnkard Book 5, Rivāyat ī Ādurfarrōbay i Farrōkhzādān, and Vizidagiha-ye Zadesparam have been analyzed based on the theoretical background of  Dalrymple and Nikolaeva (2011). The analysis of the collected data showed that in the Middle Persian Language in some cases the verb instead of the subject, agrees with the object of the sentence in number and person features. This phenomenon happens only when the sentence has the transitive verb in the past tense and there is no object agreement for transitive verbs inflected for other tenses. Moreover, the object agreement in the Middle Persian has no relation with the animacy and definiteness characteristics of the object. A comparison between the results of this research and the findings of the Dalrymple and Nikolaeva (2011) shows that object agreement is the Middle Persian is a syntactic phenomenon based on the tenses of the sentence that just occurred when the transitive verb was in the past tense. This phenomenon can show the diachronic changes of the Persian Language for the emergence of the ergative system in the Persian Language.

In the Persian language, which follows the SOV (Subject-Object-Verb) word order, the interrogative complement or prepositional object usually appears after the object in the focal position. However, it is possible to move this phrase to other positions within the sentence. The aim of this study is to investigate the processing of interrogative complement displacement in Persian using Event-Related Potentials (ERPs) based on Friederici's syntactic processing model. This study focuses on the central-parietal region of the brain, specifically the N400 and P600 components, which, according to Friederici's language processing model (1995), examine the filler-gap dependency structure and the mental representation of these phrases. Four different positions of the interrogative complement in Persian were examined, and 50 sentences were constructed for each condition.. The results indicate that the displacement of the interrogative complement leads to different brain responses, with an increase in N400 amplitude in the central-parietal region when the interrogative complement follows the subject, and an increase in P600 amplitude in the initial or focal position of the interrogative complement. These findings suggest that the displacement of the wh-complement in Persian, according to Friederici's model, has a neurophysiological basis and may represent a filler-gap dependency structure in mental representation.

This study, drawing on Conceptual Metaphor Theory and its cultural extension as developed by Zoltán Kövecses, analyzes the conceptual metaphors of Satan in the Qur’an. It aims to demonstrate how the lived experiences and cultural structures of the Arabs during the time of revelation contributed to the conceptualization of Satan as a wholly abstract entity. To this end, a corpus of 47 Qur’anic verses containing culturally grounded metaphors related to Satan was compiled and analyzed. The findings reveal that the source domains of war, the tradition of javār (protection), companionship and social interaction, and the notions of servant and captive function as culturally significant domains in metaphorically conceptualizing Satan. Among these, the jār tradition is uniquely tied to the cultural context of pre-Islamic Arab society, and while the war domain is broadly recognized across cultures, it still bears culture-specific features. In contrast, the domains of companionship and servitude are more universally understood. Each domain frames Satan in a distinct manner: as a defeated commander, a treacherous protector, an abusive companion, and a powerless laborer before God’s will. These metaphorical representations—rooted in human experience in general and that of the early Arab audience in particular—effectively deconstruct Satan’s false aura and portray submission to him as undesirable and reprehensible

With the increasing prevalence of online education, the significance of students’ self-regulation skills has never been more pronounced. Yet, many students struggle to develop and apply these skills (Bylieva et al., 2021). This transcendental phenomenological study investigates the self-regulation strategies employed by highly self-regulated university students in fully online learning environments. Participants were recruited online based on purposive and criterion sampling procedures. Data were collected through guided journals and semi-structured in-depth interviews, transcribed with Voxtab, and analyzed using Peoples' (2020) phenomenological framework and NVivo 10 software. The result revealed four major themes: meta-affective and affective practices, metacognitive and cognitive practices, socio-affective features, and tech-enhanced learning strategies. The study's trustworthiness was ensured through member checks, purposeful sampling, inter-rater agreement, and debriefing. The findings offer profound insights into students' experiences with online self-regulation. They present students with practical and effective online self-regulation strategies and provide educators with insights into course designs fostering self-regulation.

Climate change (CC) is one of the major challenges of our time that impacts rangelands regionally and globally. The rising vulnerability among pastoralists highlights the need to prioritize resilience thinking. Pastoralists' resilience refers to the ability of rangeland businesses to endure, adapt to, and remain flexible in the face of threats or challenges. This research was conducted with the primary goal of analyzing the factors that influence resilience from the perspective of pastoralists in Tehran province under CC conditions. This research was both goal-oriented and exploratory in methodology. The study sample consisted of 317 pastoralists selected through stratified random sampling. The data collection tool was a researcher-made questionnaire. Software SmartPLS was used for data analysis. The validity of the questionnaire was assessed using the average variance extracted, while its reliability was established by calculating composite reliability and Cronbach's alpha. Data were analyzed using the structural equation modeling technique with Smart PLS software. The structural equation modeling indicated that economic, institutional, ecological, physical, social, educational and extensional and individual factors had the greatest impact on Pastoralists' Resilience under Climate Change (PRCC) conditions. These factors explained 75.5% of the PRCC conditions.

Twenty five individuals of Javelin grunter, Pomadasys kaakan, collected from Abadan (29° N and 48° E) and Bandar Abbas (27° N and 56° E) stations along the Persian Gulf, was analyzed for relationship between two populations of this species, using Amplified Fragment Length Polymorphism (AFLP). A total of 410 putative loci were detected by six primer combinations, 88 of which were polymorphic (21.46%). The proportion of polymorphic loci in the Abadan and Bandar Abbas stations was calculated 88.64 and 68.18%, respectively. Average of heterozygosity in the Abadan (0.330) was higher than Bandar Abbas (0.222), which may be correlated with the environmental and ecological conditions of these stations. Nei’s genetic distance for the two populations was estimated 0.112. The phylogenetic tree revealed a clear distinction line between the two populations, supporting that dispersal of eggs and larvae in the Persian Gulf is spatially restricted. Pattern of isolation by distance was observed in this species, indicating that the gene pool of P. kaakan in the Persian Gulf was not homogeneous. The results also showed that AFLP is a potent technique for genetic fingerprinting and species identification.

The region of North Africa and the Middle East is considered one of the important geopolitical regions, which has been the focus of regional and extra-regional powers for a long time. Meanwhile, in the last days of 2010, Tunisia witnessed massive protests due to the self-immolation of a young man named Mohamed Bouazizi, which entered a new phase on January 14, 2011, when Ben Ali fled. During Ben Ali's time, Tunisia had very close relations with the United States of America and France, but after the popular protests of these countries, they demanded to accept the structural changes in this country. In the meantime, the Islamic Republic of Iran also opened relations with Tunisia after the revolution in this country due to historical, religious and cultural affinities. Therefore, we can witness the expansion of relations between the two countries in the regional and international arena. This article seeks to answer this question, what factors are effective in the geopolitical relations between Iran and Tunisia in the era after the Arab Spring? In the current research, the descriptive-analytical method and Dimetal technique were used. The findings of the research showed that variables such as trade development, diplomatic relations, holding cultural events, increasing the sensitivity of Arab countries towards Iran, strategic economic dialogues and agreements, Shiite associations and alliances in Tunisia, Shiism in Tunisia, cultural diplomacy. And... in the region, it has shown a high importance in the relations between the two countries after the Arab Spring. Therefore, in order to succeed in its relations with Tunisia, the Islamic Republic of Iran should make the most of its economic and Shiite factors.

Concentrations of lead (Pb) were found in the shells of the oyster Saccostrea cucullata and sediments in May 2010. Samples were obtained at four sites on Qeshm Island, at three sites on Hormoz Island, and at three sites in Lengeh Port along the intertidal coast of the Persian Gulf of Iran. The levels of Pb in sediments and shells were analyzed by graphite furnace atomic absorption spectrophotometer.Mean Pb concentrations in the different sampling stations varied between 613.94 and 0.06 µg g^-1 in the shells of S. cucullata and 180.78 and 0.86µg g^-1 in sediments. Biological effects criteria suggest that Pb concentrations in sediments in three sites from Lengeh Port were higher than ERL (effects range low), but at the all sites were lower than ERM (effects range medium). The present results support the significant differences in shell and sediments’ accumulated concentrations of Pb among sites attributed to input sources of human activities including urban, domestic, industrial, agricultural, shipping and transport, mining activities, and ports and harbors

This study was conducted to choose the best species for plantation on a poor drainage soil in southern coast of Caspian Sea, Iran. Nutrient concentrations in live and senescent leaves and soil properties were compared among Alnus subcordata C.A.Mey (N-fixing tree), Populus deltoides­ Marsh. (Non N-fixing tree)and Taxodium distichum (L.) Rich. (Coniferous tree) plantations. In each of these plantations and an adjacent natural forest, six 20×20m plots have been selected according to a 100m × 100m randomly systematic grid. Leaf samples of green trees were collected from the bottom one-third of the tree crown by clipping two small twigs located on opposite sides of the crown (six representative trees were sampled in each plot). Senescence leaves have been collected inside wooden trap-based in each stand. Results revealed different effects of species on soil nutrients. Alnus subcordata increased soil N (%) whereas Populus deltoides­ and Taxodium distichum reduced it.The results of nutrition, litter quality, retranslocation and soil properties indicated that Alnus improve soil quality in comparison with the two others.

Some Biochemical properties of silver carp surimi prepared by application of acid-alkali aided methods were investigated and compared to that of derived by conventional method. In terms of total protein solubility and recovery, lipid reduction, and total pigment extractability and myoglobin removal there was a significant (P<0.05) difference among the treatments. Acid-aided method showed the most efficiency to recover more proteins (86.2%) in comparison to the alkaline-aided (79.8%) and conventional (76.7%) methods. The lipid reduction percentage was recorded as 43.6%, 58.4% and 72.3% for the conventional method, and acid-alkali aided methods, respectively. In terms of total pigment removal, the conventional method showed higher efficiency (P<0.05) compared to the pH-shifting methods. Conversely, fish protein solubilisation by acid-alkali aided techniques was more efficient (P<0.05) compared to the conventional method of making surimi. In conclusion, pH-shifting techniques were superior in comparison with the conventional method in order to recover more functional proteins and to efficiently reduce the lipid and myoglobin content of resultant fish protein isolate.

Asiatic citrus canker is a devastating disease resulting in drastic economic losses in citriculture worldwide. Amongst three different types of the disease, i.e. A, A* and A^w, the A* type is genetically less known. In order to comprehend the behavior of the Asiatic citrus canker A*-type strain (Xanthomonas citri subsp. citri) in the vicinity of the host cells, a targeted semi-quantitative transcript analysis approach via RT-PCR was carried out. A subset of sixteen genes, as representative of different steps involved in phytopathogencity, was analyzed on the culture medium (as uninduced) and compared with the subset isolated from the infected Mexican lime (Citrus auarntifolia L.) plants (as induced). The results showed that certain genes were up-regulated in induced condition, suggesting a putative role in bacteria-host interaction. Furthermore, the transcripts in induced condition could be classified into constitutive, early- and late-responsive genes, demonstrating their functional relevance during the host-pathogen interaction.

Today, carbon dioxide emission is one of the concerns of all countries in the world, so in this paper, we examine the effect of export quality, energy efficiency, and economic complexity on CO2 emissions per capita during the period of 1990 to 2014 in emerging economies. For this purpose, first, energy efficiency is calculated using mathematical programming methods (DEA). Then, the effect of export quality, energy efficiency, and economic complexity on per capita carbon dioxide emissions in the panel of emerging economies is investigated using panel quantile regression. The energy efficiency results show that the average energy efficiency of the studied countries had been increasing from 1990 to 2014. The lowest efficiency score among the studied countries is related to China. The results of quantile regression indicate that the export quality and consumption per capita of fossil fuels have a positive and significant effect on CO2 emissions per capita in all quantiles. The results also show that the coefficient increases by moving in the level of quantiles, so that, the highest effect coefficient of export quality on CO2 emission is related to the quantile 90th and about 0.874. Energy efficiency has a negative and significant effect in all quantiles except 90th, and the highest coefficient of influence (0.133) is related to quantile 10th. The increase in economic complexity increases the co2 emissions in all quantiles except 10th, and the highest coefficient (about 0.487) is related to quantile 90th.
