Tense plays an important and determining role in human verbal communication; therefore, one of the things that should be addressed in language teaching is the discussion of time and ways to recognize it. Considering the role and importance of grammatical tense recognition in language learning and the lack of related research regarding Persian language learning, the purpose of the present research is to investigate the role of available cues in sentences to recognize grammatical tense by Chinese Persian learners of beginner and advanced levels; For this purpose, 49 Persian learners of Chinese language were selected by available sampling method and divided into two groups of Chinese language beginner (26) and advanced (23) based on the level determination test. The instruments used in this research were two tests in two stages; In the first stage, by using the sentence recognition test, the subjects marked the time of the sentences they heard in the answer sheet, and in the second stage, the same test was performed; with the difference that in this test, the sentences did not have time adverbs. The results of this research showed that the subjects of the beginner Chinese language meaningfully used lexical clues when recognizing the time of the sentence, and the subjects of the advanced level simultaneously used two lexical clues and present tense. Regarding the role of gender, the results showed that there is no significant relationship between gender and the ability to understand sentence time. The results of this research can be useful for language learners, teachers, and producers of educational content and also for test designers.

The present study aimed to investigate the effect of gender on the L1-L2 syntactic processing in balanced bilinguals who learned their L2 at the age of seven. Using event-related functional magnetic resonance imaging (ER-fMRI), Turkish-Persian balanced bilinguals (15 women and 15 men) performed an auditory grammaticality judgment task with an alternating language switching paradigm. Based on the Bilingual Dominance Scale, no significant difference was observed between the participants' proficiency in their L1 (Turkish) and L2 (Persian). Imaging results demonstrated strong neural similarity between men and women in two left-lateralized syntax-specific ROIs (Pars opercularis and posterior superior temporal gyrus), supporting the indistinguishable gender performance during L1-L2 syntactic processing. In addition, in EF-specific areas in right-hemisphere (planum temporale, supplementary motor area, superior parietal lobule and superior frontal gyrus), we did not observe differences in hemispheric recruitment by men and women, evidencing empirically for gender sameness in lateralization. Therefore, the present task and sample are not consistent with the previous claims that women show (a) superior language performance and (b) less lateralization. In general, our findings suggest that L1 and L2 syntactic processing in balanced bilinguals is not affected by the gender parameter.

The current research aims to investigate the universality of the language by examining the perception of Persian learners in recognition of subject position according to the theory of input processing and the principle of the first noun from this theory. The first noun principle indicates that language learners consider the noun or pronoun that comes at the beginning of the sentence as the subject of the sentence.The participants in this research are 70 Persian language learners at elementary (23 participants), intermediate (23 participants) and advanced (24 participants) levels in the Persian language learning center of Al-Zahra University. Using Friedman et al.'s (2004) executive method, this study has examined the principle of the first noun as a predictable path in the education of Persian learners. In this direction, a test has been designed on Google Forms, and Persian learners have participated in two different implementations of this test in a time interval of 5 months. In both of its implementations, this test included 15 sentences that the language learners had to connect to the related pictures after hearing the sentences. In order to characterize the perception of the participants from the position of the subject, 8 sentences in the second sentence were put into the passive form. The results of this study have shown that the change of sentences in the second implementation of the test caused an increase in errors in the response rate of language learners and this was reported higher in elementary language learners than in other groups.

This study examines the cognitive processes underlying the comprehension of second language idioms using two different visual instructional techniques, visual representation of literal meanings versus virtual meanings of each idiom’s visual representation. For this reason, two environments (positions) (PFL vs. PSL), two different terms (opaque vs. transparent), and two different sufficiency levels (intermediate vs. advanced) are considered, which involves common teaching methods that use dual coding theory as two different visual techniques with verbal support to teach different types of idioms. The statistical population were 67 second language learners and 63 foreign language learners who participated in this study. A term comprehension test was used before and after the training. The results of repeated measure variance analysis based on pretest-posttest comparisons showed that understanding of SL idioms is different according to the learning environment, teaching technique and the type of idiom. However, it sounds that the level of sufficiency doesn’t affect any group’s comprehension outcomes. The results show that in the SL environment, the figurative technique was more successful than the literal technique. While in the FL environment, using the literal technique compared to the figurative technique, got better scores for the language learner. PSL learners were better than PFL learners in learning terms with opaque meanings, while PFL learners performed better in learning terms with transparent meanings. The results of this investigation support the Dual Idiom Representation Model, which states that PSL learners activate their existing lexical entries and understand them figuratively, while PFL learners must analyze the idioms.

Metaverse is a space that includes the real world and virtual worlds in which people use a digital and virtual representation called an avatar to be present. Metaverse is considered as the major media of commercial advertising in the future and it will play a fundamental role in terms of audience attraction and society awareness. By adopting semiotics approach, this research analyzes the preparation of the subject and the formation of the avatar in Metaverse commercials. Ten commercial advertisements of prominent brands are chosen as statistical sample, and the virtual world of Hyundai brand on Roblox is examined as the case study because of its diverse activities. Descriptive-analytical method is carried out relying on participatory observation, in a way that the researcher experiences the field, and seeks to answer two questions: 1) What kind of discourse is applied to Subject and Object interactions? 2) What is the procedure of conversion of real body to ideal body? Results show that Subject of Metaverse should be considered as a Being-actor who continuously finds itself in a lack of meaning due to Becoming-centered situation and is called to action and achieves meaning as a result of the action. Besides, the avatar could be considered as Ideal-otherness while the dialogue between physical and virtual body is possible through the third body, which is the Imaginary body, which is the main base of sensory-perceptual receptions and leads the actions of the subject.

Aim and Introduction
Over the past few decades, the housing market has experienced recurrent boom-and-bust cycles and considerable price volatility. A significant portion of this volatility can be attributed to speculative activities. Speculators often purchase properties with the expectation of future price increases, which contributes to the formation of housing price bubble. These bubbles not only destabilize the economy but also lead to serious social consequences. As such, policymakers have consistently focused on identifying the determinants of speculative behavior and housing market bubbles. One of the government’s regulatory instruments in this domain is the transfer tax, intended to influence trader behavior and mitigate housing price bubbles. This study investigates the effect of transfer tax policies on the housing price bubble in Shiraz city.
Methodology
This research employs an Agent-Based Model (ABM) to simulate the dynamic processes of the housing market and analyze the contributing factors to price bubble formation. The model incorporates four key agents active in the housing market: sellers, buyers (including both personal-consumption and speculative buyers), developers, and real estate agencies. Data and statistics up to the beginning of 1401 (2022) were incorporated into the model to forecast housing prices in Shiraz through 1409 (2030).
Three scenarios were tested by varying the proportion of speculative buyers—30%, 50%, and 70%—and applying different transfer tax rates of 1% and 5%. The simulation explores how these variables influence the magnitude and growth of the housing price bubble under different market conditions.
Results and Discussion
The findings reveal that, regardless of the proportion of speculative buyers, the implementation of transfer taxes can reduce the housing price bubble in Shiraz. However, the extent of this effect varies with market conditions. These results align with prior studies, such as Chen (2017) and Izadkhasthi et al. (2018), which found that transfer taxes can mitigate housing price volatility.
Proponents of transfer taxes argue that speculative activities drive housing price bubbles and that such taxes increase transaction costs, thereby reducing speculative trading and contributing to market stability. For instance, with a 70% speculative buyer share and a 5% tax rate, the housing price bubble decreased by approximately 25% between 1401 and 1409. In contrast, a 1% tax rate under the same market conditions led to a 22% reduction in the bubble. However, when only 30% of buyers were speculative, the tax had a comparatively more minor effect, indicating that the efficacy of the tax diminishes when fewer speculators are present.
Conclusion
The results suggest that increasing the transfer tax rate does not necessarily reduce the housing price bubble. In scenarios with 30%, 40%, and 50% speculative buyer presence, higher average tax rates did not result in a significant reduction in the housing bubble and, in some cases, slightly intensified it. This supports earlier warnings in financial economics literature—such as those by Schwert and Seguin (1993) – that excessive transaction taxes may deter informed traders, who play a vital role in maintaining market efficiency and price stability. Similarly, Friedman (1953) emphasized the stabilizing role of rational traders in financial markets.
According to the simulation results, Article 59 of Iran’s Direct Taxes Law, which stipulates a 5% transfer tax, may help reduce housing bubbles in Shiraz and potentially nationwide. However, the optimal tax rate should be adaptive and context-specific, considering the varying proportions of speculative and non-speculative market participants. Therefore, the government is advised to collect comprehensive data on the structure of the housing market, assess the share of speculative transactions, and adjust tax rates accordingly.
Moreover, since the transfer tax only applies to documented transactions, many informal or contract-based transactions—particularly those occurring prior to property completion—escape taxation. In such cases, builders may sell properties through promissory notes or undocumented agreements, which are difficult to track and tax. As a result, it is recommended that the government strengthen monitoring mechanisms for such transactions. This includes identifying and intercepting units exchanged informally or without official documentation to ensure both effective taxation and bubble control.

Farmers in the Indus basin, Pakistan have generally switched to groundwater for additional water supplies due to the irregular supply of irrigation water; currently over 50% of the agricultural land in the basin is at least partially irrigated by tube-wells. These wells pump fresh groundwater, which essentially is the result of massive leakage from irrigation canals into the originally saltwater aquifer since the inception of modern irrigation around 1870. Resalinization of the aquifer now threatens long-term prospects of this new groundwater resource. Since building new dams has become ever more complicated, water resources planning now focuses on sustainable conjunctive use of surface and ground waters. The paper evaluates the raising of the Mangla dam, its effects on long-term groundwater balance and water-logging using an irrigation-economic model. It suggests guidelines to optimize the surface and sub-surface reservoirs by considering the farmers' action in response to government policies. Recently the Government of Pakistan decided to raise the height of the Mangla dam to substantially increase the storage capacity of the basin. This decision was based on basin-wide modelling of conjunctive use by using the General Algebraic Modelling System (GAMS)-based Indus Basin Model Revised (IBMR), which was updated for this purpose in 2000 and supplied with new data in 2002. The results of the analysis reinforced the decision to raise the dam height by 9 m instead of 12 m, which would increase water availability by 68% in the basin. One of the objectives of raising the dam height was to increase the sustainability of beneficial groundwater use in the basin by saving about 2 km3/a of groundwater abstractions.

Considering the vast changes in different aspects of life and various ways of earning livelihood, flexibility in contemporary housing design can be regarded as an appropriate solution in order to prevent from discreteness in interactions within the society and environment and among people. That is because a residence must be designed according to the changing needs of modern human. Traditional houses in Iran have already contained this concept, in modern era however, such viewpoint towards housing cannot be seen so often. Flexibility refers to the idea of adaptation throughout the time. Therefore it can be said that a flexible settlement is a house that can be adapted with the needs of the users and will lead to understanding the users’ expected demands with their own cooperation. Peoples’ cooperation in this process will increase the possibility of adaptation of housing with their needs which will eventually increase the general satisfaction of the housing. This research discusses the issue of flexibility and the related concepts in the field of housing with emphasis on some residential projects. Every settlement is depended on its user and the ground for its adaptation. Therefore, in terms of general design, we can say that settlement is dependent on both the environment and the user. Since human beings normally demand variety and  monotonous environmental conditions make human beings unsatisfied and bored; they usually have a favorable and positive view towards changes in their living environment. These varieties can range from some minor changes up to basic ones such as a change in the residential house itself. Flexibility in architectural design indicates variety. Such variety includes the possibility of adjustment and compatibility of a residential unit throughout time. It will eventually lead the building to show new varieties of its own. In order to demonstrate flexibility, the architects have to put the probable needs of the users into consideration in the process of designing. In other words, a “long-term thought” is required in designing.Flexibility in housing can be investigated from two points of views: first, from users’ point of view and secondly the innovative construction. Designing consists of four main issues: (1) structural system; (2) servicing spaces; (3) architectural design; and (4) facilities for environmental flexibility. The present study tries to express the concept of flexibility as a “new form of challenging architecture”. This is done using some examples and instances. From such viewpoint, the goal this study tries to attain is to survey the limitations and boundaries of flexible designing. This is done by analyzing the selected items. This way, the architect can turn flexibility into an opportunity and produce creative options in his/her work and design. The present study was conducted using library-based method and case study with the aim of studying and discussing the conceptual and operational grounds of housing design in different countries. The structure and main framework of the present study stands on the idea that flexibility can be used for  housing development in all eras and periods as a general concept and includes different types itself.

Background: Musculoskeletal disorders (MSD) represent one of the most frequently occurring and costly occupational issue in nursing. The nursing profession is one of the most stressful occupations today, because of the quantity and diversity of risk factors associated with the work environment. The aim of this study was to examine the relationship between burnout syndrome and musculoskeletal disorders. Material and Methods: In this cross-sectional study a questionnaire survey was carried out among 415 nursing personnel in five educational hospitals in Hamedan, Iran. Data were collected through two unnamed questionnaires including Maslach Burnout Inventory, Visual Analogue Scale (VAS). Results: Statistical analysis showed that the most commonly painful regions among the nurses were lower back (5.53%), left foot (5.08%), and head and neck (4.43%), right foot (4.90%), right knee (3.84%) and left knee (3.74%). The lowest pain, were found to be in right and left elbows (1.99%) and (1.91%), respectively. Also emotional exhaustion, depersonalization and personal accomplishment has significant correlation with musculoskeletal disorders (P = 0.000, r = 0.122). Conclusions: The results showed high prevalence of MDS among Iranian nurses that could be due to emotional exhaustion and depression.

Formalin is a common disinfectant and therapeutic agent in fisheries-related activities. Considering large variation in susceptibility of different species to formalin toxicity, it is necessary to determine its toxicity and safety margins in different species, separately. Therefore, to investigate formalin acute toxicity and safety margins on Caspian roach, an experiment was conducted in 1g Caspian roachs Rutilus rutilus caspicus. Fish were exposed to 0, 30, 40, 45, 50, 55, 60, 70, 100, 150, 200, 250, 300 and 400 ppm formalin and mortality was recorded after 0.5, 1, 12, 24, 48, 72 and 96h. 0.5-96 h LC50 values were 49-246 ppm. The lowest observed effect concentrations (LOEC) were found to be 40-150 ppm at different periods. No observed effect concentrations (NOEC) were 30-100 ppm at different periods. According to regression model for NOEC versus time, concentrations of 88.4, 80.3, 51.2 and 40.1 ppm are suggested as the maximum concentrations for 0.5, 1, 12 and 24 h bath treatment, respectively. Results showed the recommendations for formalin safety in the literatures are not applicable and valid for Caspian roach. Such differences could be due to species or experimental differences which should be taken into account before treating.

Outsourcing means strategic use of other company's resources to accomplish business processes, which can be in the form of outsourcing or offshore outsourcing. One of the important risks of outsourcing projects is selecting an inappropriate contractor. Contractor selection process is very complex because of many and sometimes contradictive criteria. So it needs accurate investigations. The purpose of this research is to design a framework for selecting an appropriate contractor in outsourcing and offshore outsourcing and to specify the weight of each criterion. Method of data gathering is questionnaire which is distributed among internal and external managers and experts. This framework could be helpful for the managers of organizations in contractor selection decision making processes and causes risk reduction in these projects. The results showed that there are twenty important criteria in outsourcing and twenty four criteria in offshore outsourcing; some of them are contractor's innovation, financial stability and cultural adaptation. Keywords: Outsourcing, Offshore outsourcing, Contractor, Criteria, Capability.

When the elements and different components of a literary work are studied and their relation to each other and to the totality of the work is made clear,a reader can claim that she/he has had a formalistic reading of the work.Such a reading facilitates commenting on how the elements and components of the work are interrelated( vertically and horizontally). In this paper,the form and structure of a Ghazal( sonnet) of Bidel Dehlavi are re-read, using the intratextual signs.The first line reads: YEK TAARE MU GAR AZ SARE DONYE GOZASHTEI SAD KAHKESHAN ZE OJE SORAYYA GOZASHTEI The theme of this Ghazal which is continuously repeated all through the poem is "advice to return to oneself and put under observation one’s inner self in the bed of the hastening and transitory time".The subject matters of movement,passing,transition and transformation are spread all through the Ghazal .However the link between the lines of the Ghazal is not the sort of link to create a "bodily structure",rather each line of this Ghazal is a separate bead,related to the other beads by a string( the subject matters of movement and passing of time) creating a necklace( a Ghazal).

Background: Back injury in nurses is one of the most common health problems. The chronic low back pain leads to several problems including disability, daily activities, physical and emotional problems and decreasing quality of life. The purpose of this study was to assess the quality of life of nursing staff with chronic nonspecific low back pain in Yazd, Iran. Materials and Methods: This study was a descriptive-analytic study. A total of 119 nurses were selected with nonrandom purposive sampling method. Health-related quality of life of the participants was assessed using the 36-item short-form health survey questionnaire (SF-36) and analyzed through SPSS software version 20 by appropriate statistical tests. Results: This study showed that there were significant differences between the quality of life of nursing staff with chronic low back pain and Iranian normal population in all aspects (P < .0001). It was revealed that only in the area of physical function there was a significant relationship between age and the quality of life (P < .0001). Conclusion: The results confirmed the effect of income on dimensions such as physical role, bodily pain, mental health, and social function.

Following years of contamination, rivers may experience sig­nificant levels of heavy metal pollution. Our research aims to pinpoint hazardous areas in these rivers. In our specific case, we focus on the floodplains of the Meuse River contaminated with zinc (Zn). Elevated zinc concentrations can lead to various health issues, including anemia, rashes, vomiting, and stomach cramping. However, due to limited sample data on zinc con­centrations in the Meuse River, it becomes imperative to gen­erate missing data in unidentified regions. This study employs universal Kriging in spatial data mining to investigate and pre­dict unknown zinc pollutants. The semivariogram serves as a valuable tool for illustrating the variability pattern of zinc. To predict concentrations in unknown regions, the model captured is interpolated using the Kriging method. Employing regression with geographic weighting allows us to observe how stimu­lus-response relationships change spatially. Various semivario­gram models, such as Matern, exponential, and linear, are uti­lized in our work. Additionally, we introduce Universal Kriging and geographically weighted regression. Experimental findings indicate that: (i) the Matern model, determined by calculating the minimum error sum of squares, is the most suitable theoret­ical semivariogram model; and (ii) the accuracy of predictions is visually demonstrated by projecting results onto a real map.

In recent times issues such as competition, technological complexities, specialization of tasks and cost increases causes organizations to reconsider their managerial models and to turn to new strategies for reaching competitive advantage. Two such strategies are concentration on core capabilities and the transfer of some activities to external organizations (outsourcing). In line with these trends banks in order to give appropriate services to customers, decrease costs, upgrade service quality, improve performance, increase flexibility, gain access to new skills and technologies and focus on key capabilities, outsource some of their activities. Although outsourcing can have advantages for organizations, it has risks which must be effectively managed. The purpose of this research is to identify these risks and investigate their impact on business process outsourcing of banks.  Tejarat bank of Iran was selected as a case study. The data gathering tool of this paper was a questionnaire that was distributed among the experts in the field and managers of Tejarat bank. The results show that among identified risks, strategic risks were rejected and the three risks of financial failure, performance and social-psychological kind were accepted as being valid by experts. It was further identified that performance risks have the highest importance among other risks of business process outsourcing.
