Abstract
Aims: Foodborne infections caused by bacteria, including Salmonella enteritidis, Shigella flexneri, and Escherichia coli O157:H7 are one of the most common diseases among poultry and humans. The purpose of this study was the simultaneous and rapid detection of important microorganisms found in fecal samples of poultry and poultry workers.
Materials & Methods: A total of 144 fecal samples were taken from poultry and poultry farms workers. Fecal swabs were cultured on specific media, and biochemical tests were performed for further confirmation of bacterial isolates. Moreover, genomic DNA of fecal swabs was extracted for molecular identification of S. enteritidis, E. coli O157: H7, and S. flexneri species using multiplex-PCR technique.
Findings: According to the multiplex-PCR technique results, 16.7, 13.9, and 9.5% of the poultry samples were positive for the presence of S. enteritidis, E. coli O157: H7, and S. flexneri species, respectively; whereas culture method results showed the corresponding prevalence rates of 18.1, 15.2, and 12.5% for the above species. Moreover, regarding the samples collected from the poultry farms workers, multiplex PCR showed the prevalence rates of 6.9, 12.5, and 4.2% for S. enteritidis, E. coli O157: H7 , and S. flexneri species, respectively; whereas culture method showed the corresponding prevalence rates of 8.3, 13.9, and 13.9% for the above species.
Conclusion: In the current study, the sensitivity and specificity of multiplex-PCR in detecting S. enteritidis, E. coli O157: H7, and S. flexneri species were 74 and 100% for samples taken from the poultry farms workers, and 82.2 and 100% for samples taken from the poultry, respectively, suggesting the possibility of using a designed multiplex-PCR method for rapid detection of infectious agents in poultry farms.

Abstract
«نظریه عام کلیشه‌ها» یکی از نگاه‌های صورت‌گرایانه قرن بیستم به ادبیات عامیانه است که به تأثیر از مطالعات عامیانه، عبارت‌شناسی و واژگان‌شناسی صورت گرفت. جی. ال. پرمیاکوف زبان‌شناس و نویسنده روسی، با نوشتن کتاب از مثل تا قصه‌های عامیانه (1968) چارچوب نظری این نظریه را بنیان نهاد و با بررسی عناصر بازتولیدی زبان از قبیل ضرب المثل‌ها، چیستان، کنایات، قصه‌ها، و هرگونه عبارت قالبی و فرمولوار زبان در تقابل با متون تولیدی و خلاق زبان، نظریه عام کلیشه‌ها را معرفی نمود. پرمیاکوف و برخی هم‌نظران وی برخلاف گروهی که عقیده داشتند در آفرینش‌های ادبی باید از عناصر کلیشه‌ای زبان پرهیز شود و چندان نظر مساعدی به‌این‌گونه عبارات نداشتند، تلاش کردند که علت وجودی کلیشه‌ها و فواید ساختار آن را توجیه کنند. و نشان دهند که کلیشه‌ها صرفاً مشتی عبارات دست‌دوم، کهنه و پیش‌پا افتاده نیست. پرمیاکوف از منظر زبان‌شناسی، نظریه عام کلیشه‌ها را ارائه می‌کند و حدود طرح کلی نظریه‌اش از ضرب‌المثل‌ها (کوچکترین واحد ادبیات عامیانه) تا افسانه‌ها (بزرگترین واحد ادبیات عامیانه) را شامل می‌شود و بیشتر به دنبال تحلیل ساختاری واحد‌های ادبیات عامیانه است. با استناد به عنوان فرعی این کتاب: «یادداشت‌هایی درباره نظریه عام کلیشه‌ها» می‌توان ادعا نمود که این نظریه هنوز کامل نیست و پرمیاکوف بیشتر به دنبال طرح مقدماتی این نظریه بوده‌‌است. هدف ما از ارائه این نوشته، معرفی این نظریه و جایگاه آن در نقد ادبی است و برای این منظور، تلقی زبان‌شناسان و منتقدان ادبی را از منظر محققان شعر شفاهی و نیز صورتگرایان درباره ادبیات عامیانه جستجو نموده‌ا‌یم.

Abstract
Most debates on the role of trade openness and the wage inequality are based on the well-known Hecscher-Ohlin and Stopler-Samuelson (HOS) theories. According to the Heckscher-Ohlin theory, Countries have comparative advantages in those goods for which the required factors of production are relatively abundant locally while the Stopler-Samuelson theory refers to the income distribution effects of trade openness.
In this paper, a computable general equilibrium (CGE) model and social accounting matrix (SAM) approach are used to assimilate the effect of tariff cuts on the earnings of production factors and relative wages by using Iran's data for 2001.
The results confirm that general tariff cuts lead to a decrease in wage inequality while it leads to an increase in wage inequality in the foods, apparel and textile sectors. However, tariff cuts in agriculture sector reduce wage inequality.

Abstract
Aims: Health-promoting hospitals seek to institutionalize the concept of prevention and health promotion among staff, empower patients in the hospital, and provide proper hospital interaction with the community, which improves the quality of services provided to people and communities. This study aimed to investigate strategies for improving the standards of health-promoting hospitals in the selected hospitals in Iran using the importance-performance analysis matrix in 2021.
Instruments & Methods: The present mixed-method study consisted of two phases. In the quantitative phase, data related to the importance and performance of health-promoting hospital standards were collected in the selected hospitals using the World Health Organization questionnaire. In the qualitative phase, the weaknesses and strengths of the selected hospitals were identified using the importance-performance analysis matrix, and solutions to improve them were presented using the focus group method. The statistical population was managers and officials of 4 selected hospitals in Iran. By census method, 65 people were selected, and 61 people participated in the study. One-way ANOVA was used to compare the performance scores among the hospitals.
Finding: Non-government hospitals had higher mean performance scores in the standards of health-promoting hospitals. According to the importance-performance analysis matrix, standards for promoting a healthy workplace, continuity, cooperation, and patient evaluation were identified as critical points and the waste management policy standard of the selected hospitals.
Conclusion: Setting up appropriate educational programs regarding the promotion of staff health and staff participation in hospital policies, determining and evaluating the health promotion needs of different groups of patients recommended.

Abstract
This paper investigates the impact of exchange rate on non-oil export covering the period from 1978 to 2006. The method used in this study is Panel data, and these countries are selected as the hosts: Turkey, The United Arab Emirates, Saudi Arabia, Kuwait and Pakistan. In this research, Gross Domestic Product of the host country, Bilateral Exchange Rate, Price Raito and Dummy Variable are used as regressor for non-oil exports. The result of this study shows that, gross domestic product and exchange rate have positive effect, but price ratio and dummy variable have negative effect on non-oil exports of Iran to these countries. Also Cross Section Specific coefficient shows that exchange rate has positive effect on export to Turkey, The UAE and Pakistan, while negative effect on other countries.

Abstract
In recent years, coopetition—the collaboration between competitors—has gained significant attention from businesses. Within the healthcare supply chain, coopetition strategies are employed to address shortages in equipment, infrastructure, human resources, and raw materials. This approach is increasingly relevant in today’s complex and dynamic business environments and requires specific human resource competencies to effectively manage changing market conditions. However, there has been a lack of research on these competencies in this particular context. This study was conducted in two stages using a mixed-methods approach, with a statistical population comprising academic and industry experts. In the first stage, semi-structured interviews and thematic analysis identified 30 competencies related to human resources in coopetition. These competencies were categorized into seven groups: "personality competencies," "knowledge competencies," "communication competencies," "ethical competencies," "task competencies," "security competencies," and "decision-making competencies". In the second stage, a researcher-made questionnaire and a fuzzy total interpretive structural model were used to explore the relationships among these competencies. The results indicate that "personal competence" and "ethical competence" are foundational competencies from which other competencies arise. Following these, "knowledge competencies," "communication competencies," and "decision-making competencies" hold greater significance than the others. Based on these findings, it is essential to prioritize personality and ethical skills in human resource recruitment, while enhancing knowledge, communication, and decision-making abilities through in-service training.

Abstract
Flap-type WECs are used On-Shore to generate electricity and pump. The draft depth and incident wave frequency are parameters affecting the performance of this type of converters. In this paper, the effect of water draft depth and incident wave frequency on the performance of a converter at a scale of 1: 8 investigated experimentally. The power take-off system is hydraulic. The Caspian Sea was also selected as the target sea. After calibration and uncertainty analysis, experimental tests performed in the wave-flume of BNUT by regular waves. Considering the period of the Caspian Sea ([4-8] s), Froud scaling, the tests were performed in the period interval of [1.6-2.5] s, which is equivalent to the frequency interval [0.4-0.63 ] Hz. Also, due to the importance of the converter's draft, the converter's performance was evaluated from the draft of -0.1 (submerged flap) to 0.6 m. According to the results, the best converter performance was at the lowest frequency; the converter performance decreased with increasing frequency. The best converter performance was obtained at the dimensionless draft of 0.43 (equivalent to 0.4 m draft), and the converter power was reduced at larger and smaller draft. It is worth noting that at a negative draft (submerged flap), the converter has the lowest performance. The maximum values of flow, power and pressure on a laboratory scale were 0.14 liters per second, 21.3 watts and 156.8 kPa, respectively, which were measured at 18 liters per second, 22.66 kW, respectively, using Froud scaling method. And will be 1249/61 kPa

Abstract
The conflict between mathematical rules and beliefs, as well as the correct choice, is an ethical issue. The resolution of this conflict depends on providing a criterion for evaluation so that the moral agent can make the correct choice based on it. This current research addresses the standards and trends in conflicting requirements through an analytical approach from the perspective of psychological egoism concerning self-love and Islam. Psychological egoism, which is based on the inclination towards self-love, perceives greater good and pleasure in adhering to mathematical rules. This thinking often neglects other perspectives in calculations by focusing solely on global systems and expressing certain truths. Although some Quranic verses affirm part of this perspective, other verses indicate alternative directions and their superiority. Therefore, monopolizing the stance on self-love is incomplete and does not encompass all truths. From the viewpoint of Islamic scholars, reason evaluates conflicting parties based on fundamental rules of conflict, where preference is more significant than obligation. Compliance with God's essential requirements is crucial, and thus dismissing unnecessary demands is a prerequisite for beliefs prior to mathematical rules. Creating a relative consensus towards modifying mathematical rules that conflict with beliefs is another method to resolve these conflicts.
