Abstract

Language teacher professional identity refers to each individual’s understanding of their identity, helping them prepare for their professional lives and is affected by different factors. This study thus explored the reasons why language teachers chose this profession, their perceptions of the notion of language teacher professional identity (LTPI), the influential factors in the formation or change of professional identity, and the contribution of communities of practice. A 37-item questionnaire along with five open-ended questions was developed and administered to 109 English language teachers studying Teaching English as a Foreign Language (TEFL) at Iran University of Science and Technology (IUST). The outcome of the study revealed that language teachers perceived their professional identity mostly related to students, self-knowledge and awareness, and practice into knowledge. They stated that students, context, and disciplinary knowledge could greatly cause constant change in the progression and formation of professional identity. The research could shed more light into the improvement of language teachers’ professional development and teacher education programs.

Abstract

Writing assessment literacy(WAL) for second or foreign language (L2) teachers, which refers to teachers’ knowledge, conceptions, and practice of writing assessment in L2 contexts, has lately received attention from scholars. Although there has been significant debate about the impact of contextual and conceptual factors on teachers’ assessment literacy, studies focusing on how such factors influence teachers’ WAL are lacking. The purpose of this qualitative study was to explore the way Iranian English writing teachers' conception of assessment, and macro, meso, and micro contextual variables impact their writing assessment practice. It also looked at how writing teachers make assessment decisions in order to negotiate and find a compromise when their assessment views and beliefs diverge from the assessment policies in their local contexts. The data was collected through semi-structured interviews with ten in-service l2 writing teachers in Iran. The findings show that participants had positive conceptions about formative writing assessments but they stated that they mostly used summative assessment in writing classes. Macro level contextual factors turned out to mostly impacted teachers’ writing assessment practices and conceptions. The results underscored the role of school and work experience in shaping and changing writing assessment conceptions. The findings of this study contribute to our current understanding of WAL development and provision of more efficient assessment training for language teachers in teacher education programs.

Abstract

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.

Abstract

I aim to explore whether there are similarities and differences between the ethical virtues and vices in Nahj al-Balāghah in terms of cognitive-linguistics and based on the image schemas of Evans and Green's Model piety, perseverance, expenditure are the ethical teachings, described in Nahj al-Balāghah, chosen and analyzed based on image schemas. And the vices described in Nahj al-Balāghah are Secularism, greed, and jealousy. Studying the descriptive-analytical approach, I investigate and compare the virtues and vices discussed in sermons and short sayings of Nahj al-Balāghah in terms of cognitive semantics. Finally, the findings reveal that the general types of image schemas of Evans and Green’s model (schemas of Force, Balance, Unity/ Multiplcity, Existence, Identity, Locomotion, Containment, Space) have almost similar frequencies for both the virtues and vices. Among all, the schemas of force are the most repetitive in virtues and vices. And the balance is on the second level. The research finding is significant because it shows the similarity of the virtues and vices in using the different types of schemas in Nahj al-Balāghah. Their main difference lies in the way of using the subsets of the general concepts.

Abstract

This study investigated the construct validity and measurement invariance of the Teacher Emotion Questionnaire to introduce a valid and reliable instrument for assessing English-as-a-foreign-language (EFL) teachers’ emotions inside the classroom. Second language (L2) teacher emotions have been largely neglected, despite the fact that Educational Psychology has long recognized and researched the role of teacher emotions in different aspects of teaching and learning. To bridge this gap, the current study had 208 Iranian EFL teachers in private language institutes fill out the Teacher Emotion Questionnaire (TEQ), which assessed six emotions teachers experience in their classroom, i.e., Joy, Pride, Love, Anger, Fatigue/Exhaustion, and Hopelessness. The preliminary analysis of the data showed that six items from the TEQ had a factor loading below the minimum recommended level of 0.3, meaning that they contributed to the total variance in the participants’ score less than expected. The collected data were then submitted to confirmatory factor analysis (CFA) for the purpose of construct validation and establishment of the factorial structure of the TEQ. The CFA results indicated that the hypothesized six-factor analysis had more favorable goodness-of-fit indices than both a one-factor structure and a two-factor structure (e.g., positive versus negative emotions). Multilevel CFA revealed that the tested six-factor structure of the TEQ was invariant across male and female EFL teachers. The implications for the use of TES in EFL teaching contexts are discussed, and some suggestions are proposed for further validation of the TEQ in language teaching contexts.

Abstract

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.

Abstract


 Over the past decades, research on language teacher engagement in action research (AR) has received a surge of interest. However, little research is available on how teachers’ experience contribute to their development of agency and professional performances through their participation in an AR program. Accordingly, this study explored the role of experience in five novice and five experienced language teachers’ development of agency and practice before, during, and after their engagement in an action research engagement program (AREP). To this end, we collected data via semi-structured interviews, reflective journals, and classroom observations. The findings revealed that novice and experienced teachers’ development of their agency and professional practice undergo similar trajectories. Moreover, the study argues that although experience affects teacher-researchers’ agentive role and performances, novice and experienced teachers go through similar paths as they engage in AR. However, the novice teachers became more oriented towards reflection-in-action during and after their engagement in AREP. Moreover, the novice teachers chose more AR tools and drew more on their AR experience which, in turn, facilitated their professional growth through tool transformation. We conclude the paper with implications for teacher education to better understand the role of AR in teachers’ agency development and professionalism.

Abstract

The current study identified EFL teachers' emotional experiences in technology-equipped classes from an appraisal theoretical framework (Frenzel, 2014). It further explored the underlying antecedents of the recognized emotions and sought instructors' suggestions for improving the current unpleasant feelings experienced. To this end, 10 EFL teachers took part in the study. Necessary data were collected through journalkeeping and semi-structured interviews. The obtained data were analyzed using Merriam's (2009) inductive approach. Research findings revealed that teachers enjoyed the class as a result of students' achievement, positive interactions among learners, and pupils' active involvement. Moreover, they felt proud if they received positive feedback from students, observed progress in students' learning, and felt capable of instructing the learners. Furthermore, shame was experienced because of feeling unable to work with technical tools, strong filtration on educational websites, and not having internet-connected systems in class. Anger was also reported to be felt if they had to work with obsolete or impaired devices. Finally, teachers' pity was aroused as they perceived the lack of professional technical tools as detrimental to students' learning. They also mentioned that they felt compassion for learners as they cannot take part in CBTs and have limitations accessing e-sources online. Teachers also argued that unpleasant emotions could be minimized through investing in equipping classes, holding training courses, and establishing a criterion for teaching evaluation. In the end, the implications and limitations of the study are discussed.

Abstract

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.

Abstract

This study investigated the relationships between self-esteem, empowerment attitudes, and perceptions of classroom justice among EFL (English as a Foreign Language) learners. Relative stratified sampling was used to choose the 329 participants that make up the research sample. Cronbach’s alpha was used to assess the reliability of the questionnaire. This study used path analysis within the framework of structural equations, using a descriptive-correlational methodology, to analyze data and test research hypotheses. Software such as AMOS22 and SPSS22 were used to analyze the collected data. The results showed a significant correlation between students' perceptions of classroom justice dimensions and their feelings of empowerment and self-worth. The implications extend beyond the confines of the classroom, pointing towards a holistic approach to education that considers both the interpersonal dynamics within the learning environment and the individual empowerment of students.

Abstract

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

Salt stress is a serious environmental threat reducing crop yield. Hence, developing any breeding plan requires an understanding of the basic physiology and cell molecular genetic regulation under salinity stress. In this study, we evaluated the effectiveness of gene expression changes on ion homeostasis comprising salt overly sensitive (SOS1) and vacuolar Na+/H+ antiporter (NHX1) along with ion content measurement and proline content in the rice mutants at Rice Research Institute of Iran in 2018-2019. To survey these realities, tolerant mutant genotypes (em4hs290 and em4hs84) along with Hashemi parent cultivar, IR28 (sensitive), and FL478 (tolerant) seedlings were treated with 100 mM NaCl. Based on the results of growth indices, the seedling length of Hashemi cultivar and IR28 decreased considerably about 44.7%, and 44.2% reduction to that of the control, and the leaves progressively yellowed. Results showed that proline content and K+ and K+/Na+ ratio increased about ~2–3-fold higher in the tolerant genotypes than in the susceptible ones. Also, the overall amount of the OsNHX1 and SOS1 expression increased in tolerant genotypes compared to the susceptible ones. Accordingly, the compatible solute accumulation significantly advanced resulting in improvement of ionic homeostasis and probably suppresses the stress. Moreover, the variable pattern of gene expression in the two salt-tolerant mutants (em4hs290 and em4hs84) and Hashemi parent showed that the induced mutation could increase the salt-tolerant in mutant genotypes through ionic and osmotic homeostasis. Generally, these tolerant mutant genotypes could be applied to develop salt-tolerant varieties in rice breeding programs which can bring on production sustainability.

Abstract

This study investigates the factors affecting coffee exports in Cameroon. For this purpose, we employed the gravity model. Considering the sample characteristics, the model is estimated with the Poisson pseudo-maximum likelihood (PPML) method. The main material of the study is a panel data set covering the years 2001-2021 for ten countries, Cameroon’s main coffee export partners. The findings show that the GDP of importing countries, coffee export prices, and bilateral investment treaties (BITs) positively influence exports, whereas distance, exchange rates, and Cameroon’s GDP have negative impacts. The results highlight Cameroon’s logistics infrastructure deficiencies and the significance of stable, high-quality production. The Cameroonian government should implement policies to improve production quality and efficiency by expanding agricultural extension services and offering farmers input and investment incentives to address these challenges. Additionally, improving port efficiency will necessitate the digitalization of operations, implementation of data-driven planning, and strategic infrastructure investments.

Abstract

The agricultural ecosystem provides various functions and services for humans. So, investigating their role and importance in the agricultural land programming and management is one of the goals research. In this research used Common International Classification of Ecosystem Services (CICES) for the identification of the Agricultural Ecosystem Functions and Services (AEFS). Also, Multi-Criteria Decision-Making (MCDM) models used for weighting and prioritizing of the AEFS like Step wise Weight Assessment Ratio Analysis (SWARA) for calculating of their weight, and Simple Additive Weighting (SAW), Additive Ratio Assessment (ARAS), and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) used for prioritization them. The research data extracted with field survey, random sampling and completing the Delphi questionnaire of the 40 agricultural specialist experts in the north of Iran. Also, the R2 coefficient was used to compare the AEFS prioritization models. The SWARA technique findings showed that provisioning, regulation, and cultural functions with weights of 0.0298, 0.0286 and 0.0250 have the highest weight, respectively. Also, the results indicated that the SAW model with the R2=0.90 was chosen as the prioritization appropriate model. Provisioning, regulation, and cultural functions with marginal weights of 0.6319, 0.5448, and 0.5092 were ranked the first to third priority respectively. Also, food supply, employment, genetic material supply, and educational and research services were important positive services of the agricultural ecosystem compared to other services. it is suggested that more appropriate programming and more research be done by relevant organizations for the sustainable management of agricultural ecosystems in northern Iran.

Abstract

The present study was aimed to investigate the effect of predicting variables of quality of life (hexagonal capitals, place attachment, benefiting of governmental services) and psychological coping strategies of Iranian farmer families facing climate variability. The method this research was survey, and the current research was analyzed using structural equation modeling. The participants were all farmer families living in the villages. The data were collected with a questionnaire and a stratified random sampling method. Findings revealed that variables of the proposed model were able to explain 69% of the changes quality of life under climate variability conditions. The results demonstrated that hexagonal capitals and place attachment had a positive and significant impact on psychological coping strategies and quality of life of farmer families. The implementation of specific interventions with the aim of farmers’ capitals reinforcement, paying attention to rural infrastructures and psychological interventions in order to enhance the resistance capacity of farmer families against climate variability has been recommended.

Abstract

Sluice gates are commonly used to measure water discharge and to adjust the water level in open canals. Sluice gates can also be used at the crest of dam spillways for controlling floods. Estimation of head loss (∆E/E0) and discharge coefficients (Cd) for a sluice gate is essential for the design of open canals. Depending on the downstream water level, free or submerged flow conditions may occur. Although there have been some investigations on Cd for sluice gates, a comprehensive literature review shows that there are no studies of ∆E/E0 (to the best knowledge of the authors). Knowledge of ∆E/E0 is necessary for the design of intakes and irrigation canal inverts. This study uses the physical model of sluice gate to introduce helpful charts for energy loss estimation. Experiments were conducted in the University of Tabriz, department of water engineering. A rectangular canal with length of 12 m, width of 0.5 m and height of 0.8 m was used. Vertical slide gate was installed at the 6 m from canal inlet to permit flow become uniform. Water circulation is carried out using a submerged pump. Water is pumped in a 4.5 m head tank and then inters to canal with pipes. Water level/depth was measured with a point gauge with 0.1 mm accuracy. Discharge was measured with a calibrated rectangular sharp crested weir. Experiments were carried out with different discharges and gate opening. Results show that E for free flow is greater than that for submerged flow conditions. Meanwhile, discharge coefficients in a free flow are greater than those under submerged flow conditions. Relative energy losses (∆E/E0) have a minimum value of 0.271 and a maximum value of 0.604. These high energy losses cannot be ignored in intake structures and canal-designing processes and their impact on minor canal inverts receiving water from main canals should be considered. The relative energy loss changed from the minimum value of 0.271 to the maximum value of 0.604. Multivariate regression method was used to calculate the relative energy loss and the average of the residuals was -0.004. The maximum and minimum residuals for ∆E/E0 are 5 and -0.31, respectively. A mathematical equation with a coefficient of determination of 0.925 was presented to separate the boundary of free flow from submerged flow. To estimate the discharge coefficient in submerged flow, a mathematical equation was obtained. For this equation, the average of the residuals was -0.004. The maximum and minimum residuals for the discharge coefficient are -0.084 and 0.116, respectively. Application of multiple non-linear regression (MNR) models are presented for predicting ∆E/E0 and Cd. The high energy losses cannot be ignored in intake structures and canal designing processes. Their impact on minor canal inverts receiving water from main canals should be considered. Application of MNR was presented from a simple equation to more sophisticated equations by improving regression relations in each step. The MNR method provides accurate equations for predicting performance for both ∆E and Cd.

Abstract

Aim and Introduction
Today, the environment is considered as one of the most important pillars of sustainable development, and the development of other economic and social sectors depends on its sustainability and proper functioning. Environmental pollution has become one of the main challenges of countries. Environmental health is currently one of the most critical concerns of people and officials round the world. Almost all managers and decision makers believe that this national wealth should be protected not only for the current generation but also for future generations, since the pollutants caused by industries are highly costly and detrimental to health.
Active industries are one of the main sources of environmental pollution. One of the necessary conditions for economic progress and the introduction of extensive structural changes in economic and technological fields is industrialization and industrial development. In the production process, using production inputs whose main source is the environment, in addition to desirable outputs such as consumer goods, undesirable outputs such as environmental pollutants are also produced. If the number of outputs is not controlled and disproportionate, the losses from undesirable outputs will be greater than the benefits of desirable products in such a way that damages to the environment would be irreparable and sustainable development less likely to be achieved.
One of the most important concerns related to industrialization is the effects and environmental consequences of industrial activities. Therefore, achieving the necessary solutions to control such consequences is vitally important. Minerals are essential for human survival, but their extraction and processing are not environmentally friendly practices which contribute to problems such as soil erosion, air and water pollution. On the other hand, mineral sector is one of the largest energy consumers which has active contribution to air pollution and global warming. The main purpose of this study is to investigate the economic effects of Gol Gohar mine in Sirjan. For this purpose, it is intended to determine the type and amount of pollutants released from this complex, and also to determine the amount of the green tax of the complex as a solution to reduce pollution and examine the social welfare resulting from reducing pollution.
Methodology
In this study, the economic effects of environmental pollutants of Gol Gohar Iron Mine in Sirjan (Southeastern Iran), is investigated using the input distance function model from 2001 to 2022. Through calculating the shadow price of pollutants, a criterion for determining the green tax is determined, and then the amount of social cost resulting from the emission of pollutants is calculated.
The shadow price of the undesirable output is the cost that the producer must bear if they plan to reduce the production of the undesirable output. In fact, it can be interpreted as the marginal cost of reducing pollution for each producer. Therefore, the shadow price of the desirable output is considered positive and equal to the market price of that output, but the shadow price of the undesirable output must be estimated to be less than zero.
Findings
The products of Gol Gohar Iron Ore Complex in Sirjan, include granulated iron ore, iron ore concentrate and pelletized in the production process. The most greenhouse gases and air pollutants are related to carbon dioxide (CO2), sulfur oxides (Sox), nitrogen oxides (Nox) and particulate matter (SPM). According to the obtained results, the average shadow price for air pollutants in Gol Gohar complex for CO2, Sox Nox, and SPM was calculated as 11.15, 3,074.5, 5,529.62, and 1,875.62 rials per kilogram respectively. Moreover, the average total social costs resulting from the production of Gol Gohar Sirjan Complex was calculated as 92,710 billion Rials according to the amount of pollution produced over the period.
Discussion and Conclusion
The estimation of environmental costs is actually an introduction to providing solutions for internalizing and reducing environmental costs, using the input distance function model and the shadow price of environmental pollutants in the industrial and mineral complex of Gol Gohar, Sirjan. The title of the largest producer of iron ore in the country was calculated, and the social cost resulting from the emission of pollutants was also evaluated. Finally, in this study, solutions and mechanisms for reducing environmental costs have been proposed.
Considering that the ability to absorb pollutants by the environment is limited, the shadow price of pollutants, which represents their real social cost, should be taken into consideration. The damages should also be determined based on the shadow price of the pollutants. In other words, the amounts of pollutant emission should be calculated and while taking into account the allowed limit of pollutant emission and shadow prices, based on a legal plan, the environmental costs should be reimbursed. Taking such measures would surely require more studies and capable executive management system

Abstract

  Aim and Introduction
Ecological footprint accounting is composed of two metrics, the “demand-side” (ecological footprint) and the “supply-side” (biocapacity). While the ecological footprint calculates the demand for natural assets in global hectares, biocapacity symbolizes the supply capacity of nature to meet this demand with the same unit of measurement. Ecological deficit also shows the difference between ecological footprint and biological capacity. Globally, the degree of ecological deficits continued to expand over the last decade due to the increase in EF and reduction in biocapacity, which is caused by the following: increasing consumption of fossil fuel energy, overexploitation of natural resources, unsustainable production methods, and economic activities.
Iran is one of the countries that has a weak environmental performance. According to the Global Footprint Network, Iran's ecological footprint exceeded 333% of its biological capacity in 2022. Iran's ecological deficit, which was - 0.55 global per capita hectares in 1961, has increased by 554% to 2.50 global per capita hectares in 2022, and the destruction and pollution of the environment in Iran have reached unsustainable levels. Therefore, the analysis of the determinants of environmental quality can provide insights into the design of appropriate environmental policies in Iran. 
In this regard, the environmental effects of dependence on crude oil have attracted considerable attention. Crude oil is an important and largest source of energy, especially for developing countries such as Iran. It is a fossil-based fuel and a major source of carbon emissions in the world. Hence, many studies have linked oil price shocks to environment quality. In contrast to oil-importing economies, where oil price increases encourage a shift to cheaper and cleaner alternative energy sources, the environmental policy issue in oil-exporting countries is entirely different. Indeed, a fall in oil prices may be associated with a decreased investment in environmentally friendly energy sources. By comparison, an increase in oil prices revealed a reluctance to diversify the economy away from its reliance on non-eco-friendly fossil fuel energy.
Based on the explanations above, the main purpose of this article is to investigate the asymmetric impact of scaled oil price impulses on the environmental Load Capacity Factor (LCF) in Iran using the Non-linear Autoregressive Distributed Lag (MATNARDL) approach. The paper intends to make the following contributions to the literature. Firstly, this article is the first to look into the effect of oil prices on the LCF in Iran by applying asymmetric methodologies. Secondly, it is the first study with a reverse load capacity factor as an environmental sustainability indicator. Thirdly, this paper applied the advanced and newly developed MATNARDL for asymmetric and nonlinear analysis to provide a more robust result that exhibits relevant policy implications. Finally, this innovative study investigated the effects of oil prices on the LCF in Iran between 1961 and 2022 in the framework of the LCC hypothesis.
Methodology
The study compiles annual data for the period 1961-2022 for Iran from three different sources. According to Statista, OP represents average annual OPEC crude oil price (in US dollars per barrel). The data are obtained from the World Bank, GDP per capita, (constant 2015 dollars), Energy Consumption (EC) as kg of oil equivalent per capita, Ecological Footprint (per capita, gha) and LCF (the load capacity factor) are obtained from Global Footprint Network. Because the LCF includes biocapacity in the numerator and EF in the denominator, it allows for simultaneous environmental assessment on the supply and demand sides. A higher LCF indicates a better environment. The current paper's economic functions are illustrated in Equations (1):

LnLCFt=fLnOPt, LnGDPt,LnGDPt2,LnECt,εt                                               (1)
The main objective of this study is to examine the major, medium and minimal scales of positive and negative changes in oil price on the environmental quality index in Iran. For this purpose, the MATNARDL is used as an estimator to examine the effect of minor to major adverse shocks and minor to major positive surprises in the explanatory variable on the explained variable.
Findings
The bounds cointegration test results confirm a long-term relationship in the asymmetric model. The estimation of the model has been performed by categorizing the positive and negative impulses of the oil price in three small (quantiles less than the τ30 threshold), medium (quantiles between the τ30 and τ70 thresholds), and large (quantiles greater than the τ70 threshold) scales in the form of MATNARDL approach. The results indicate that in the long term, small scale of positive (negative) oil price impulses had a positive (negative) and significant effect on the load capacity factor; while these impulses have a negative effect on the load capacity factor in the long term in both medium and large scales. Based on other results, energy consumption has a negative and significant effect on the load capacity coefficient, and the environmental hypothesis of the load capacity curve (LLC) in Iran is confirmed.
Discussion and Conclusion
Based on the obtained results, it can be said that the effect of oil price on the load capacity factor in Iran is asymmetric. Among positive impulses, only with increase in small scale of oil price, we can see an increase in load capacity factor and environmental sustainability in the country. Moreover, the positive impulses of the oil price on both medium and large scales lead to the increase of environmental instability by prioritizing economic achievements and activities over environmental issues

Abstract

Abstract TAZKERAT - AL - ULIA is the only work by Farrid - Al - Din Attar in prose form. It expresses the biography, ideas and deeds of seventy two mystics and sofism. The reflection of historical, political and literary events affairs and creation on the works of Attar in particular , and Farsi literature of that time in general is quite interesting. In order to study the dramatic aspects of Tazkerat –Al –Ulia it is necessary to read, analyse and evaluate them in a different set of literary and artistic terms, that is to say dramatic and theatrical terms. The elements of theatre contain elements of play, performance, dramatic devices and techniques. In order to reveal the theatrical capacities and potentials of Tazkerat – Al - Ulia a selection of its narratives (three stories) 1 - Fozail Ayyaz, 2 - Rabee Advieh, 3 – Hosein – Ebn - Mansour Hallaj is in the center of present study and their theatrical and dramatic aspects of the prementioned stories have been analysed and evaluated in theatre critical terms. The researcher hopes that her research findings has shed light on the theatrical and dramatic potentials and values of Tazkerat –Al –Ulia and paves the way for dramatization and stage adaptation of the stories of the work in question.
