Despite the substantial significance of communicative goals in EFL, pragmatic aspects of instruction that are geared towards the learners’ appropriacy still remain less than adequately addressed. Such a niche offers potentials for and stimulates a proliferating body of research. This study aims at examining the effectiveness of explicit vs. implicit pragmatic instruction regarding language performance as output. For the purpose of the study, 120 (60 male and 60 female) EFL learners took part in this project. Error Recognition Tests (ERTs), Discourse Completion Tests (DCTs), role-play, and writing assessments were used for gauging pragmatic output. Two separate 3×2 mixed between-within-subjects factorial ANOVAs were conducted to examine the effects of instruction type, proficiency level, and time (treatment) on pragmatic acquisition. Findings significantly support (a) the overall benefit of pragmatic instruction, (b) the effect of both implicit and explicit instructions with explicit type being more highly influential, (c) the effect of proficiency, and (d) the interaction effect of proficiency and pragmatic instruction on pragmatic language L2 use. Findings bear implications for enriching teaching and learning contexts, deepening theoretical concerns, improving pedagogical practice, and implementing communicative syllabus design. Keywords:

The multi-core spatial structure is one of the important and basic topics in urban planning studies, which is considered both as a framework for evaluating urban development and as a basic spatial development goal. Considering the importance of the multi-core spatial structure pattern, especially for large cities with high populations and diverse and complex activities, the present study aims to evaluate the spatial structure of Tabriz city from the perspective of multi-core pattern development based on the spatial distribution of functions and population across the city. The present study employs a Quantitative Correlational Research method. The documentary method is used for data collection, and various techniques such as mean center, standard deviational ellipse, kernel density estimation, location quotient (L.Q.), nearest neighbor index, and geographically weighted regression are applied for data analysis. The study examines six functions: religious, educational, commercial, healthcare, industrial, and administrative. The findings suggest that the spatial distribution of functional cores, except for industrial and commercial functions, exhibits a single-core spatial structure in the city center. Also, the results indicate that the correlation between functional cores and the population of Tabriz city, based on the spatial regression test, is moderate. Accordingly, an imbalance in the distribution of functional cores in Tabriz City is evident. Therefore, Tabriz is located in a single-core state, and due to the increase in the distribution of administrative and medical functions in the eastern and industries in the western, it can become a multi-core model.

The color temperature of light is one of the important indicators in lighting that should be considered. Because people experience and feel their surroundings not only with brightness and darkness, light and shadow but also through colors, the feeling that the color of the light creates in the space affects human perception and health through the warmth and coldness of the light. The color receptivity and color temperature chart is a tool that determines how the human eye feels when faced with a spectrum of light. Since the purpose of this research is to analyze the light quality of the s tained glass windows of traditional Iranian architecture, calculating the color temperature will be a suitable criterion for judgment, that is, if the color temperature of the light from the s tained glass windows is calculated, the experience of people in facing the light can be calculated quantitatively. Comparative methods were used to analyze the quality of light based on the color temperature curve with calculation tris timulus values XYZ from spectral data and calculation xyz chromaticity values. Inves tigations showed that the light color temperature of 65% of the windows is 3000 to 4600 K, and 35% is. In these windows with this combination model and area percentage of four colors, red, green, blue, and yellow, the quality of light has not decreased based on the color temperature curve.

Technological progress has transformed the payment industry. Although alternative payment instruments such as bank cards share some characteristics with banknotes, they are not direct competitors to cash. First, cash possesses unique attributes—its functionality without electrical power and its inherent anonymity. Second, statistical data indicate that the ratio of cash to M1 has stabilized at approximately 10% in recent years, primarily due to its substitution with demand deposits. In this paper, we model the demand for banknotes by incorporating technology-related characteristics alongside conventional theories of money demand. Our approach has important implications for central bank, particularly in liquidity management, currency issuance, effective management of physical currency, and continued investment in digital payment infrastructures. We adopt a macroeconomic perspective that considers banknote demand from both transactional and asset viewpoints. To this end, we estimate an autoregressive distributed lag (ARDL) model, which allows us to analyze both short-term and long-term coefficients within a framework of model uncertainty. A key focus of our study is the estimation of a payment system development index using logistic growth and Gompertz models, through which we assess its impact on cash demand. Our empirical evidence supports the notion of S-shaped growth in the adoption of payment technologies. The findings demonstrate that advancements in the payment sector have led to a significant decline in cash demand. Moreover, while increased real economic activity exerts a positive and significant influence on cash demand, a higher opportunity cost of holding cash has a pronounced negative impact.
