- چکیده انگلیسی: Assessment, as a key component of education, has long been a matter of concern to teachers and it receives even more significance when perceived from the view point of ethics. The combination of the two concepts, i.e. ethical assessment, is difficult to define and complicated to measure. But prior to all these comes how teachers perceive it. The present research reports on a study of English teachers’ perception of ethical assessment. Following Green, Johnson, Kim, and Pope (2007), 108 English teachers were asked to state their opinions about ethicality or unethicality of 40 prevalent assessment practices classified into seven themes: test preparation, communication about grading, multiple assessment opportunities, test administration, grading practices, confidentiality, and neutrality. The findings suggest that respondents displayed consensus on only two fifth of the scenarios. To delve into the reasoning behind participants’ choices, 2 participants were interviewed for each scenario and the findings, also, were thematically compared with those reported in literature.

- چکیده:
- چکیده انگلیسی: Teacher identity has recently been under extensive investigations to understand its impacts on and relationships with classroom variables. Considering the effect identity has on individuals, an immediate relationship is that between teacher identity and an index of an effective teaching, i.e. teacher efficacy. The present study tries to understand the possibility of a direct relationship between the two concepts. 37 English teachers were given an efficacy scale to gauge and rank their efficacy indices. The top 5 participants in teacher efficacy list were then regularly observed during an academic semester and interviewed to study their institutional identity. Meanwhile, similar procedure was conducted for 5 teachers with the least teacher efficacy scores, too. Detailed qualitative analysis of interview transcriptions and observation notes revealed the two groups were distinct regarding their institutional identity. In other words, it was shown that institutional identity and teacher efficacy were positively associated with each other.

- چکیده: اثر عملکرد دراماتیک زنده
- چکیده انگلیسی: Drama is a composite art, a mixture of literature and many other arts, originally written to be performed, since its proper appreciation depends on its being observed, not just read. A play is not fully a work of dramatic art until the text is transformed to action and sound (Rezai, 1992). The performance of the text will reveal many indicative clues to the discovery of the theme, characterization and symbolism of the play. In our academic environments, however, all courses designed to teach drama focus on the written text, and almost no effort is made to incorporate the theoretical analysis of the text with the unparalleled experience of watching the live dramatic performance of plays. The present study undertakes to examine how effective this experience can be on the students’ understanding and evaluation of drama. For this purpose, an intact group of the students of English literature in Islamic Azad University, Rasht Branch, all at the same level of academic education, were chosen and randomly divided into two groups. A pretest determined their similar level of language proficiency before hand. The treatment, i.e. theoretical discussion and critical evaluation of a play, Sophocles’ Antigone, plus watching its live performance, was implemented in the experimental group for at least 10 sessions. The final step was the administration of a posttest for both groups to estimate to what extent they acquired the ability to the successful analysis of the dramatic work presented to them. The statistical analysis revealed that the experimental group which was offered the chance of theoretical discussion of the text and watching the play yielded more satisfactory results.

- چکیده:
- چکیده انگلیسی: Background & aim: Forensic midwifery is a new major which has been established in response to the need of endangered women for forensic services and also the lack of service provision in this domain. However, there are ambiguities in the definition of this major and its scope of practice. The present study was conducted to investigate the scope of practice in forensic midwifery.
Methods: In this integrative review, the articles related to the subject of interest were searched in several database including PubMed, Scopus, CINHAL and Google Scholar. All kinds of publications including reviews and standards, qualitative, quantitative, or mixed methods studies were included in the review regardless of the publication date. The data related to the scope of practice in forensic midwifery were extracted using a wide and in-depth analysis, in addition to using an expert panel for validation. To do the analysis, every concept representing scope of practice was coded and similar codes were classified into themes.
Results: The search process resulted in retrieval of 43 articles. Based on the reviewed papers, the scope of practice in forensic midwifery divided into four categories including the practices related to reproductive issues, violence, malpractice in obstetrics and gynecology profession, and the improvement of the professionalism in midwifery domain.
Conclusion: Considering the potentials of forensic midwifery, the graduates of this major could have an important role in the protection of women’s rights in forensic situations.- انتشار مقاله: 29-05-1398

- چکیده انگلیسی: Objective(s): Integrons, as a potential element in the distribution and maintenance of drug resistance, have thoroughly been established. It is known that the high prevalence of integrons in multidrug-resistant (MDR) clinical isolates has become a serious public health concern. The objective of the present study was to determine the frequency of different classes of integrons in clinical isolates in Iran.
Materials and Methods: Electronic global databases were systematically searched. The raw data for integrons among bacterial isolates were collected and their prevalence was analyzed using Comprehensive Meta-Analysis V2.0 (Biostat, Englewood, NJ, USA) software.
Results: In a comprehensive literature review, 29 eligible studies were determined with their meta-analyses indicating the prevalence of integron class 1 to be 41% (95% CI 36.3-46.1) and integron class 2 as 17.7% (95% CI 13-23.3) in Gram-negative bacteria. The highest prevalence of integron class 1 was reported in Acinetobacter spp (58%) while the highest prevalence of integron class 2 was reported in Shigella isolates (83.7%). The frequencies of class 1 integron in MDR (79%) and non-MDR isolates (41%) were higher than those for class 2 integron in MDR (13.4%) and non-MDR isolates (17.7%).
Conclusion: The current systematic review demonstrated the significant presence of integrons among clinical isolates. Our analysis showed that measures such as estimates of the prevalence of this transposable element and diligence in continued surveillance might be necessary to prevent its spread.- انتشار مقاله: 30-02-1397

- چکیده: در این مقاله تحلیل تنش و کرنش شانه محور بیرونی و شانه محور درونی هد برداشت جدید برنج با استفاده از روش المان محدود ارائه میشود. این هد برداشت شامل سامانه جدا کننده دانه از ساقه بوده که هریک از شانههای محورهای بیرونی و درونی عضوی از این سامانه میباشند. از نرمافزاز اباکوس با حلگر صریح دینامیکی برای انجام واکاوی، و از بلوکهای هشت گرهای و المانهای تتراهدرال به منظور المانبندی قطعات استفاده شد. پس از اتمام شبیهسازی، نمودارهای تنش و کرنش قطعات رسم شده و مقادیر بیشینه آنها در هر یک از قطعات تعیین شد. از روش تحلیلی به منظور صحت سنجی نتایج حاصل از شبیهسازی و همچنین محاسبه ضریب اطمینان و تعیین عمر هر یک از قطعات استفاده شد. حداکثر میزان نیروی اعمال شده بر روی هر دندانه شانه 29/4 نیوتن بر میلیمتر بود. حداکثر تنش در هر دو شانه 43/44 مگاپاسکال بدست آمد. نتایج نشان داد ضریب اطمینان خستگی تمام قطعات از ضریب اطمینان تسلیم آنها کمتر است. بنابراین قطعات زودتر دچار خستگی میشوند. عمر محاسبه شده برای هر یک از قطعات بیشتر از ۱۰۶بود. بنابراین قطعات (شانه محور بیرونی و شانه محور درونی) در محدوده عمر نامحدود قرار دارند. خط رگرسیون با ضریب تبیین ۹۸/۰ بر دادهها انطباق داده شد و همچنین اختلاف بین دادههای پیشبینی شده از روش المان محدود و محاسبه شده با روش تحلیلی در محدوده ۸۹/۷± بود. بنابراین میتوان نتیجه گرفت که انطباق قابل قبولی بین دادههای پیشبینی شده و محاسبه شده، وجود دارد.
- چکیده انگلیسی: This paper presents stress and strain analysis of outer shaft shoulder (OSS) and inner shaft shoulder (ISS) of a new paddy harvesting head (PHH) using finite element method (FEM). Snapping grain unit is a part of this head, with OSS and ISS as its members. The analysis was performed using the ABAQUS software with Dynamics Explicit Solution Method. Eight-node block and four-node tetrahedral elements were used to mesh the parts of the head. After the analyses, the stress and strain curves, and their maximum values were estimated for various parts. Analytical method was used to verify the FEM results and to calculate the factor of safety (FS) of the OSS and ISS components and also to estimate the number of cycles to failure of each component. The maximum amount of force applied to each tooth of shoulder was 4.29 Nmm-1. The maximum stress in both shoulders was obtained as 44.43 MPa. Other results showed, fatigue factors of safety for all components were less than their relevant yield factor of safety. Therefore, the fatigue in components would occur first. The study showed the predicted life for OSS and ISS components is more than 106 cycles, thus the components have an infinite-life. A fitted regression line to the data showed that the calculated stresses from analytical method lie within bounds of 7.89 % of the predicted values with a coefficient of determination of 0.98. Hence, it could be concluded that there is a good agreement between the analytical and FEM results.
