- چکیده:
- چکیده انگلیسی: The study intended to examine the effects of Telegram on Iranian EFL learners' vocabulary knowledge and the attitude of them towards vocabulary learning. To this end, a group of 100 Iranian advanced EFL learners participated in an experimental design project. The participants were selected after they took the Oxford Quick Placement Test and they were divided into experimental and control groups. The participants of both groups had a three-week vocabulary instruction. The treatment was similar for both groups except for exercises done after the class. The participants in the experimental group were asked to fill out an attitudinal questionnaire after the treatment. Then, a vocabulary test was administered among the participants of both groups. Results of the independent-samples t-test run on the collected data indicated that participants of the experimental group outperformed those of the control group. The findings of the attitudinal questionnaire showed that the participants had positive attitude toward using Telegram. The conclusion drawn is that those in the experimental group were free in using the online group to interact with each other. Within this framework, learners in the experimental group indicated that they enjoyed this instruction as it was fun to embark on new technological learning methods

- چکیده:
- چکیده انگلیسی: Abstract This study was intended to compare collaborative and individual task planning effects on Iranian EFL learners’ writing performance. Therefore, a group of 90 upper intermediate EFL learners were placed in three groups of Collaborative Task planning, Individual Task planning, and Control. In the experimental groups, participants were asked to do task planning collaboratively and individually. The first writing assignment was the pretest and the eighth one was the posttest. A rating scale which includes five equally weighted criteria for rating; namely, Organization, Content, Grammar, Mechanics, and Style as well as the Total score was used. After making sure about the inter-rater consistency, data were analyzed using one-way ANOVAs to examine the effects of task planning on EFL writing performance. Results indicated that task planning produced better writing performances in the experimental groups, when considering Total scores. Furthermore, the treatment was effective in Organization and Style. Nevertheless, it had no significant effects on Content, Grammar, and Mechanics. Results are in line with previous research on collaborative writing and task planning. However, the study was different because it made a distinction between collaborative and individual task planning. This study has practical implications for classroom practices and language teachers, and theoretical implications for a better understanding of sociocultural theories of second language learning.

- چکیده:
- چکیده انگلیسی: This study investigates the role structural priming plays in production of passive structures among Iranian EFL learners. In order to answer the research question, which asked whether structural priming effects result in an increase in the production of the target structure (i.e., passive structures), 60 Iranian EFL learners participated in the study. After taking the placement test, they were divided into four experimental and control groups, namely Experimental High-Proficiency, Experimental Mid-Proficiency, Control High-Proficiency, and Control Mid-Proficiency. Participants then took part in picture description sessions the results of which were subjected to a 2 x 2 analysis of variance. The results of the experiment showed that priming resulted in increased production of the target structure in question by experimental groups as compared with production by control groups. In addition, the results indicated that EFL level of proficiency made a significant difference in production of the target structures. It is believed that structural priming can be employed as an alternative technique for presenting certain grammatical structures

- چکیده:
- چکیده انگلیسی: Background: The global cancer incidence and the number of survivors are increasing. Therefore, it is necessary to pay more attention to the side effects of treatment. Aim: The aim of this study was to assess the effect of reflexology on the side effects of chemotherapy in cancer patients. Method: For finding the related articles, the researchers searched several databases including PubMed & ProQuest and valid websites including ScienceDirect, Google Scholar, Scientific Information Database, and Magiran. The key terms of “reflexology, cancer, and chemotherapy” individually and combined together were searched in Parisian and English, and the studies performed from 2009 to 2018 were extracted. Due to the lack of sufficient studies carried out into the outcome of reflexology on chemotherapy, both Persian and English articles were used. Results: A total of 57 studies were extracted from the databases and valid websites; five of which met the inclusion criteria. All selected studies were clinical trials. Implications for Practice: Reflexology can be used as a non-pharmacologic nursing intervention to alleviate the side effects of chemotherapy and improve the quality of life of cancer patients.

- چکیده: در پژوهش حاضر دیدگاه اساتید زبان انگلیسی دانشگاه، تمرین های کلاسی و چالش های آنان در رابطه با ارتقا استقلال زبان آموز مورد بررسی قرار گرفت. این پژوهش از نوع تحقیق ترکیبی بود و در آن از دو ابزار پژوهشی استفاده شد: پرسشنامه دیدگاه معلمان(بورگ و ابو سعیدی، ۲۰۱۲) و بحث گروهی متمرکز. نخست پرسشنامه به صورت آنلاین در اختیار اساتید قرار گرفت و تعداد صد نفر به آن پاسخ دادند. از میان آنان پنج استاد با سابقه ی بیش از ده سال تدریس داوطلب شرکت در بحث گروهی متمرکز شدند. تحلیل داده ها در قسمت کمی و کیفی نشان داد که اغلب شرکت کنندگان به نقش مثبت استقلال زبان آموزان در یادگیری زبان، همچنین نقش برجسته ی معلمان به عنوان تسهیلگر و راهنما تاکید دارند. اساتید باور داشتند ابعاد روانشناختی و اجتماعی استقلال زبان آموزان در مقایسه با بعد سیاسی و فنی، از اهمیت بیشتری برخوردار است. آنان همچنین ابراز داشتند که ارتقا استقلال زبان آموز با این حال که هدفی ایده آل خواهد بود، اما در مورد عملی بودن آن تردید داشتند. این شک به دلیل عواملی چون تاثیر سیستم آموزشی، خصوصیات شخصی و تجارب قبلی زبان آموزان و معلمان بود. اساتید در مورد سطح استقلال زبان آموزان در بررسی کمی، اختلاف نظر داشتند اما در قسمت کیفی، با اتفاق نظر اعتقاد به پایین بودن استقلال زبان آموزان داشتند. در انتها به ارائه پیشنهاداتی جهت ارتقا سیستم آموزشی پرداخته شده است.
- چکیده انگلیسی: The current study explored the Iranian EFL instructors’ perceptions, practices and challenges related to learner autonomy (LA). Applying a mixed method design, two kinds of instruments were used: Teachers’ beliefs questionnaire derived from Borg and Al-Busaidi’s study (2012) and a follow-up focus group discussion. First, the questionnaire was answered by 100 university instructors. Then, to have a knowledgeable focus group who can yield profound dependable information, five EFL instructors with more than 10 years of intensive experience were asked to take part in the interview. The data analysis in both quantitative and qualitative strands indicated that the majority of the participants highlighted the importance of fostering and practicing LA among learners and stressed teachers’ essential role as facilitators and guides. Teachers revealed more inclination toward psychological and social aspects of LA rather than political and technical ones. Moreover, while considering LA enhancement as a desirable goal, they showed doubt concerning its practicality due to the constraints in the educational system, learners characteristics, and teachers’ factors. Regarding the degree of LA, the questionnaire showed mixed ideas of teachers, while the focus group participants believed in the lack of LA among EFL students. The findings of the study can have some pedagogical implications for enhancing LA in the Iranian educational system.

- چکیده:
- چکیده انگلیسی: Objective(s): Radiation therapy for breast cancer can induce myocardial capillary injury and increase cardiovascular morbidity and mortality. A prospective cohort was conducted to study the prevalence of myocardial perfusion abnormalities following radiation therapy of left-sided breast cancer patients as compared to those with right–sided cancer.
Methods: To minimize potential confounding factors, only those patients with low 10-year risk of coronary artery disease (based on Framingham risk scoring) were included. All patients were initially treated by modified radical mastectomy and then were managed by postoperative 3D Conformal Radiation Therapy (CRT) to the surgical bed with an additional 1-cm margin, delivered by 46-50 Gy (in 2 Gy daily fractions) over a 5-week course. The same dose-adjusted chemotherapy regimen (including anthracyclines, cyclophosphamide and taxol) was given to all patients. Six months after radiation therapy, all patients underwent cardiac SPECT for the evaluation of myocardial perfusion.
Results: A total of 71 patients with a mean age of 45.3±7.2 years [35 patients with leftsided breast cancer (exposed) and 36 patients with right-sided cancer (controls)] were enrolled. Dose-volume histogram (DVH) [showing the percentage of the heart exposed to >50% of radiation] was significantly higher in patients with left-sided breast cancer. Visual interpretation detected perfusion abnormalities in 42.9% of cases and 16.7% of controls (P=0.02, Odds ratio=1.46). In semiquantitative segmental analysis, only apical (28.6% versus
8.3%, P=0.03) and anterolateral (17.1% versus 2.8%, P=0.049) walls showed significantly reduced myocardial perfusion in the exposed group. Summed Stress Score (SSS) of>3 was observed in twelve cases (34.3%), while in five of the controls (13.9%),(Odds ratio=1.3). There was no significant difference between the groups regarding left ventricular ejection fraction.
Conclusion: The risk of radiation induced myocardial perfusion abnormality in patients treated with CRT on the left hemi thorax is not low. It is reasonable to minimize the volume of the heart being in the field of radiation employing didactic radiation planning techniques. Also it is advisable to screen these patients with MPI-SPECT, even if they are clinically asymptomatic, as early diagnosis and treatment of silent ischemia may change the outcome.- انتشار مقاله: 06-04-1393
