The increasing ubiquity and impact of audiovisual content has turned it into one of the primary objects of study in a number of disciplines in humanities, including Translation Studies. In the recent decade, audiovisual translation (AVT) has been a thriving research focus in many parts of the world. This article aims at mapping AVT in the context of Iran by reviewing the published Persian AVT research worldwide. The article is organized into two parts: the first part provides an overview of the main research articles, delineating the main research trends in AVT research in Iran. The second part presents and discusses research gaps and areas that merit further scholarly attention by academia. The article concludes that research on the topic in Iran is still in a fairly early stage, with the studies focusing mainly on dubbing and subtitling of audiovisual products. Furthermore, areas such as accessibility and inclusion, in particular, voice-over and game localization are grossly under-researched. To fill the gap, certain areas are highlighted and recommended for future research.

The optimal implementation of Computer Assisted Language Learning (CALL) in Iranian EFL higher education faces some challenges despite its incremental growth. It is, therefore, necessary to investigate the current challenges affecting university professors' and students' adoption of CALL in Iranian EFL contexts. For this purpose, data were collected through semi-structured interviews with three purposeful sampling groups of participants, both before and after the temporary shutdown of the educational sector due to COVID-19 spread. Therefore, 33 interviewees—university EFL professors, students, and Information Technology Support Engineers (IT-SE)— took part in an interview which took approximately 90 minutes for each, conducted in person or over WhatsApp and Skype platforms. All the interviews were audio recorded and transcribed for thematic analysis by the first researcher and an assistant researcher. The obtained results highlighted nine major categories of themes that indicated the obstacles and challenges of optimal CALL implementation. These challenges are related to 1) technological dimension, 2) teacher dimension 3) student dimension, 4) software and hardware dimension, 5) sanctions and filtering dimension, 6) curriculum dimension, 7) the nature of e-learning dimension, 8) socioeconomic and cultural dimension, and 9) university administrators' dimension.  It was the sanctions and filtering dimension, the nature of e-learning dimension, and the socioeconomic dimension that were exclusive to this study. Each of these major themes includes a set of minor themes. The results can contribute to educational planners, curriculum and material developers, and teachers to develop education programs for optimal CALL implementation in Iranian EFL higher education by removing the challenges.

Choosing the active or passive constructions for the native speakers of a language, as the name suggests, is simply a "choice" and "selection" and the speaker uses one of these two voices to express the meaning according to his situation and recognition. This conscious choice between the two structures mentioned is not a problem as long as the speaker speaks his native language. The problem begins when a person wants to speak or write in another language and for his “choice”, among the data and training that he has received in a foreign language up to this point, he looks for a reason to choose the best option among two voices and not allow errors. This article tries to answer the question: how can students for whom Russian is not their native language consciously choose a passive construction? In other words, this article is not intended to compare the Voice in Persian and Russian or to observe students’ “mistakes” in encountering this category. The article is aimed at developing a questionnaire containing the “correct” options from among the types of quasi-passive, passive and active and implementing it for 86 students of the Russian language in Iran and Russia (for whom Russian is considered a non-native language) and, based on the analysis of their answers, to reflect them "trend" in the use of passive structure. From this point of view, we try to help Russian teachers in teaching the use of the passive voice.

This research aims to study the effect of the internal aspect of the language in the development of the perception of meanings and its function in the translation process and to study the role of reminiscence and association of the translator's prior knowledge of meanings when choosing an equivalent in translation. However, in translation, only one of its semes will be able to manifest itself. But, when evaluating the equivalents chosen in literary translation, we sometimes encounter cases that indicate that the translator has gone beyond the usual vocabulary related to the semantic field of this word. The fundamental question is: in these cases, the question of choosing an equivalent is based on which intralinguistic factors and which elements of the language influence this choice? So, based on the opinions of Humboldt, Erdmann, and Gauker regarding the dimensions of language and the translator's thinking, a semantic study of the equivalents selected in three Persian translations of André Gide's novel Strait is the Gate was conducted. This comparative study demonstrates the translator's transition from the external to the internal domain of language to represent secondary meanings. Accordingly, although the translator can traverse the internal aspect of language thanks to his cultural and literary knowledge, to convey the semantic idea and figurative meaning that resides in the word in the source language, he needs a connection between his linguistic knowledge in the source language and his postulationist conception in the target language.

Abstract:
Zarrin Qabā Nāme is a huge verse in 23133 couplets that probably has been versified in the Safavid period. Its poet is unknown and beginning of itś matter is coming of Solomonś messenger (Zarrin-qabā) to Keyxosrowś court and his confronting with Iranians. Afterwards several stories are narrated that their important persons are Sistanś heroes. Structure, language and content of Zarrin-Qabā-Nāme are storytelling-folklotic. Therefore, studying of its important motifs is useful in knowing and completion of Iranian folk- storytelling literatureś motifs. In this paper, some of these kinds of points and motifs are studied in four parts: 1) Semitic and Islamic matters 2) Rare and single indications, 3) Other matters and contents, and 4) Modeling from other stories.

Cabbage leaf miner Scaptomyza flava (Fallen) (l)iptera: Drosophilidae) is a native and oligophagous leaf miner insect on cruciferous plants (Brassicaceae). It occurs in many parts of the world and throughout Khuzestan. The relationship between feeding and ovipositional preferences of insect, and host plant suitability on seven host plant species (cauliflower Brassica oleracea var. botryds, green cabbage B. oleracea var. capitata, hedge mustard Sisymbrium officinale, brussels sprout B. oleracea var. germmifers, turnip Brassica rapa, cucumber Cucumis mtivits, wheat Triticum aestivum and rice Oryza saliva) was evaluated. Ovipositional preference of 5. flava was determined by measuring feeding punctures and egg density after ndult female flies were given a simultaneous choice and non-choice of all host plants for feeding and oviposition. Studies were performed under greenhouse conditions. The experimental design was a randomized complete block one with 8 treatments and 5 replications of each treatment. S. jlava showed distinct hierarchical ordering in its ovipositional preference, with turnip, green cabbage, and hedge mustard being preferred over all others. Approximately 1.05 and 5.8 times more eggs were deposited on green cabbage than on turnip and cauliflower respectively. When the percentage of punctures with eggs was calculated for each species, cauliflower had by far the highest value at 10% and 19.7% in choice and non-choice tests respectively. For all other species on which eggs were laid it was less than half this. In non-choice tests, females laid more eggs on green cabbage and turnip than other brassicas.

Background: This study aimed to assess the influence of video games on voice learning in students of speech therapy.
Methods & Materials: This study was a clinical trial study in which 102 fifth semester students of speech therapy group of Ahvaz Jundishapur University of Medical Sciences took part and were divided into two groups. The first group included 27students who were admitted in the university from 2008and2009 trained in traditional training and the second group (N = 75) who were admitted in 2010, 2011, 2012, and 2013 spent their traditional training plus using the software of Avaz-e-Ma. at the end of each semester. Students' satisfaction of the learning of each group was obtained through using the qualitative scale and the final exam of each group. The relationship between the learning type and the student scores was analyzed using Pearson correlation coefficient and the difference between of both groups were analyzed by independent T-test.
Results: The mean age of the first and the second group were 20.11 ± 3.02 and 20.25 ± 2.12 years old respectively. The mean score of the students who learned by software were 18 ± 0.2 and the students by traditional way was 12 ± 0.2 that was significant difference (P < 0.001). The majority of the students (90%) believed that the use of software has been useful.
Conclusion: The use of educational games in the classroom leads to an increase in the students' grades and the satisfaction of the students with the quality of instruction. Accordingly, using technology in educational system is recommended.

The relationship between female oviposition preference and offspring performance is a key area of study on the evolution of host specificity. This study investigates host prefer-ence of the polyphagous hover fly Syrphus ribesii (Diptera: Syrphidae) and compares it with some components of its offspring`s performance. Females and offspring were tested on six naturally used aphid hosts (blackberry, dock, nettle, pea, rose, and sycamore aphids). In the laboratory, larvae were able to develop successfully on aphids which were rarely selected for oviposition by gravid females. Despite the relatively small differences in performance resulting from feeding on different aphids, there was evidence for a pref-erence-performance correlation in the generalist S. ribesii.

Wetlands as a situ for the growth of native plants, as a habitat for certain species of fish and aquatic birds, and because of their potential economic, cultural and recreational services, are valuable heritage so their protection and conservation is very essential. Mostly due to the absence of wetlands services’ valuation, lack of special regulations, and lack of guarantee for these properties, resources and services of wetlands are not utilized appropriately, and destructed and evacuated in a free and unrestricted fashion, leading to inefficiency in use. The purpose of this study is the economic valuation of Gavkhony wetland ecosystem attributes, estimation of implicit price for attributes, impact assessment of socio-economic variables such as age, marriage, indigenous, family size and education on willingness to pay (WTP), and analyzing welfare and compensation variation due to variation of hypothetical policy. The approach being used is choice experiment that is a subset of choice modeling procedure and stated preference method. Data were collected from six different choice experiments provided in the questionnaires, which were filled out by 500 randomly selected households in Isfahan and Varzaneh cities in the spring and summer of 2013. Each questionnaire contained 72 hypothetical policies, 36 choice sets, 2442 observations and 7327 rows of data. Nested Logitech models and Hausman-MacFadden test were used in order to estimate the visitors’ WTP for improving attribute levels for Gavkhony wetland. This procedure was used on the basis of multinomial discrete choice analysis of preferences, Lancaster’s theory of value and the theory of random utility function. The Hausman-MacFadden test results showed that cross-elasticity between the first and third options was the same. Thus, these two options were placed in the second nest. The results further showed that the visitors had WTP for preserving forest diversity and vegetation of wetlands and its surrounding; preserve of natural habitats and organisms life of wetland (bird, fish and animals); wetland hygiene (preventing industrial and domestic effluent, and water salinity); and increasing the water surface (increasing wetland water inlet). The values estimated for these four aspects correspondingly were 8636, 12584, 11553 and 4740 Rials. Some socio-economic variables such as gender, marriage, age, family expenditure, education and being native had a positive impact on the visitors’ WTP. The surplus welfareresults showed that in 72 hypothetical policies, option 1 had the most positive welfare, and option 5 had the most negative welfare for the users of Govkhony wetland. The surplus welfare results based on WTP estimation provide important tools for policy making.

The strawberry spider mite (SSM), Tetranychus turkestani Ugarov & Nikolski, is an important pest of greenhouse cucumber in tropical and temperate regions of the world. The use of the host plant resistance is a basic method to reduce pesticide application in greenhouses. In this study, the biological responses of SSM to six greenhouse cucumber cultivars (Puia, Hedieh, Milad Ghadim, Milad Jadid, Khasib and Negin) were investigated. Non-choice tests were performed to evaluate the interaction between the host plant-mite. All tests of this study were carried out under laboratory conditions at 28 ± 1 °C, 60 ± 5% RH and 16:8 h (L: D) in a walk-in growth chamber. The results indicated that immature development time and adult longevity of SSM was significantly influenced by cucumber cultivars. The highest r, λ, and R₀ were 0.275 (day^-1), 1.316 (day^-1) and 36.180 (offspring/generation) all of which were recorded for the mites reared on the Hedieh cultivar. No significant difference was observed for these parameters among the other cultivars. Mean generation times of T. turkestani reared on Negin (14.020 day) and Milad Ghadim (13.57 day) cultivars were significantly longer than for the other cultivars. This mite had the shortest generation time on Puia cultivar (11.43 day). In conclusion, it seems that Hedieh and Milad Jadid cultivars are the more susceptible and resistant cultivars to the SSM than the other tested cultivars, respectively.

In a voice conversion system speech signal of A speaker (i.e. source speaker) is modified so that it sounds as if it had been pronounced by B speaker (i.e. target speaker). This process, sometimes, is called speaker conversion (changing speaker identity). Achieved signal from speaker conversion system is desired to have high quality and very natural. To satisfy this, three major methods are proposed as follows: VQ_based, LMR_based and GMM_based voice conversion methods. DTW is the most popular way to warp corresponded words in two sentences. In this paper, DTW is used to design corresponding transfer function. To decrease the distance between two speakers, DTW warps the couple phonemes of two speakers, instead of two words or couple sentences while a linear temporal transform which depends on phonemes is used for error decreasing. By using other appropriate corrections that are used in learning and designing of the linear transforms, a high quality voice conversion system is achieved.

Background: Measures of nutrient availability such as concentrations of carbon (C), nitrogen (N) and phosphorus (P) are important indicators of terrestrial ecosystems productivity. Current research illustrates the C, N and P stoichiometry of litter and soil in a coastal mixed forest stand, northern Iran.
Materials and Methods: To this, the Carpinus betulus (CB), Acer velutinum (AV), Pterocarya fraxinifolia (PF), Quercus castaneifolia (QC) species were considered; litter and soil (0-15cm depth) samples were taken under tree canopy cover.
Results: Litter and soil C: N ratio differed among the tree species, showing the highest (61.08 and 31.44) and lowest (21.90 and 3.59) under the QC and CB tree species, respectively. The litter and soil C: P ratio varied among the study sites and ranked in order of QC (52.4 and 27227.04) > PF (30 and 1465.61) > AV (15.74 and 630.54) ≈ CB (13.42 and 566.28). The higher amounts of litter N: P ratio were significantly found under QC (0.86) > PF (0.73) > CB (0.61) ≈ AV (0.55), whereas soil N: P ratio were significantly higher under CB (177.69) > PF (123.53) ≈ AV (121.60) > QC (109.25), respectively.
Conclusion: We found the species that differed in traits could influence C, N and P dynamics and its stoichiometry. The Q. castaneifolia species with different root traits that resulted in different vertical and horizontal distributions of C, N and P, reflecting differences in nutrient uptake by plants and microbial dynamics, drove the biggest changes in litter and soil C, N and P.

  The EPA production of a marine bacterium, Shewanella putrefaciens MAC1 in four selected culture media and at incubation temperatures of 4°C for 72h and 10°C for 24h was studied. Eicosapentaenoic acid was found to be the sole polyunsaturated fatty acid produced by this bacterium. The major saturated fatty acids produced were palmitic and myristic acids. The highest yield of EPA production was 34.7 mg/g dry cell weight which was obtained in a basic culture medium containing 1% peptone and 0.5% yeast extract in ½ strength artificial sea water (ASW) at 10°C. The least EPA was produced when 2% glucose was added to the basic ingredients, indicating that EPA production is enhanced by culture media having limited source of carbon. Addition of 2 mg/l desaturase cofactors NADPH (Nicotinamide Adenine Dinucleotide Phosphate) and FAD (Flavin Adenine Dinucleotide) to the basic ingredients had a significant effect on the EPA production  (21mg/g dry cell weight) at 4°C.

The contrastive  function of [spread glottis] in the description of stops and fricatives has been approved in many languages, such as English, but its role in the phonological behavior of Persian stops, not  fricatives, has been discussed yet. This paper based on Glottal timing theory shows that regarding this laryngeal feature in the description of Persian fricatives has got phonetic plausibility. By taking its contractiveness into account, Persian phonetic possibilities, then, regarding this feature has been dedicated in the framework of derivational approach. The results also show that applying this feature brings more economic and efficient analyses about some superficial unrelated phonological processes such as spirantisization of velar stop, fricativization of aspirated onsets and postfricative voicing based on autosegmental and optimality theoreis. This is why this paper suggests that voiceless fricatives together with voceless stops would form a natural class based on the shared feature, that is [+spread], and their voiced counterparts form a natural class due to shared [-spread] as well.

Although Ghazals of Hafez have been researched on in different poetic and linguistic approaches, there is always a new finding when diving in this endless ocean. In this paper discourse of signature verses (Takhallus) of Hafez are analyzed using one of the most authorized and referred theories today but ignored for some times that of Bakhtin. The Russian philosopher who claims that the author is not the only speaker but along with “other voices” in an active interaction take part in the creation of the truth. Considering this view point, it was found  that in spite of the fact that in most verses Hafez addresses himself, there is no “one” speaker. In other words he takes different varieties of viewpoints. In this way he sometimes agrees with Hafez, sometimes praises him, sometimes takes care of him, and still in other cases he opposes him, blames him, disagrees with him, or even outrages against him. Hafez is not alone, there are other voices in different layers of the discourse in a dialogic interaction. What makes this signature verses distinct is that here Hafez explicitly says that “I is an other”, “I must become the other of myself”, “I am my other self”. In this research, characteristics of polyphonic discourse are proposed as practical Models in three patterns for structural polyphony and three patterns for content or viewpoint polyphony with all the related sub-patterns.

  The present study investigates the auxiliary selection in the languages which use this way to encode perfect and progressive aspect, future tense and passive. In other words, it investigates how Persian makes use of the universal auxiliary categories, be and have, and then it attempts to find out the similarities and differences between this language and others with regard to the selection of these verbs. In the next step the gathered data is analyzed within the framework of croft (2003). The study of various languages showed that the selection of each of auxiliary verbs is not an accidental matter but represents different grammatical and historical development. It is concluded that Persian tends to select the verb be for the perfective aspect and in this way it is more similar to Germanic languages rather than Romance ones. With regard to progressive aspect this language uses the verb have and used to select the verb be before with respect to passive voice although it now uses another auxiliary verb as the production of language invention. For future tense the concept of volition remains in its auxiliary verb. Thus some Persain language usages of the auxiliary verbs follow the universal markedness hierarchy while others are restricted to a few number of world’s languages.

The aim of this study is to determine the underlying laryngeal feature of Persian obstruents in final position and their neutralizations based on the concepts of Laryngeal Phonology and acoustic measurements. Four female speakers read the words inserted in three carrier sentences. Hence the effect of three environments on neutralization phenomenon has been investigated: pre-silence word final position, pre-vowel word final position, pre-obstruent word final position. Applying Praat software (version 5315) seven acoustic correlates of voicing distinction have been extracted from the data: vowel duration, consonant duration, voice bar duration, voice rate, voice onset time, burst duration and intensity of burst. After statistical analysis, underlying laryngeal feature has been specified based on the concepts of laryngeal phonology. The findings show that the distinctive dimension in Persian obstruents is GW which is not neutralized in final position. Furthermore, Persian unmarked phonemes are passively voiced in inter-sonorant position. Thus Persian, like other Germanic languages, is an aspiration language in which GW is phonologically specified.

The aim of the present study was to identify the phytoplankton species which producing domoic acid and okadaic acid toxins in coastal waters of Banar Abbas city, and to determine the concentration of domoic acid and okadaic acid toxins in water and shellfish samples.Water sampling was performed in winter 2015 and summer 2016 from coastal areas overlooking the discharge of municipal and industrial effluents. Shellfish were collected from the coasts of Bandar Abbas and Bandar-e- Lengeh. Phytoplankton toxins were measured by kit method and instrumental analysis based on ELIZA method.Pseudonitzschia delicatissima, Pseudo-nitzschia pungens and Pseudo-nitzschia seriata were identified in the production of domoic acid, while Dinophysis caudate and Prorocentrum Lima were recorded as okadaic acid producers in the coastal waters of Bandar Abbas. Water-soluble okadaic acid showed significantly higher concentrations than domoic acid. Instudied shellfish samples (Circenita callipyga, Barbatia candida, Telescopium telescopiumandThalessa savignyi), the measured concentrations of okadaic acid ranged from 59.8 ± 2.38 to 121.96 ± 28.25 μg / kg. This value for domoic acid was from 0.85 to 83.59 ± 38.72 μg / kg.Compared to the guideline values, the observed concentrations of okadaic acid and domoic acid toxins in the studied shellfish were lower than the allowable level.  But this value was recorded for the water-soluble domoic acid above the allowable value, which requires continuous monitoring to achieve the quantitative and qualitative pattern of phytoplankton toxins in order to support the safety of the marine ecosystem users in Hormozgan province.
