The Web has become the most important information source for most of us. Unfortunately, there is no guarantee for the correctness of information on the Web. Moreover, different websites often provide conflicting information on a subject. Several truth discovery methods have been proposed for various scenarios, and they have been successfully applied in diverse application domains. In this paper, we have attempted to answer the question whether the truth is relevant. We conducted an experimental study in which we analyzed and compared the results of two different truth discovery methods: Relevance-based sources ranking and Majority vote. We have found that the truth is not always held by the most relevant sources on the web. Sometimes the truth is given by the majority vote of the crowd. In addition, we have proposed a method of presenting the results of truth discovery with gradual degrees of belief. A method that allows to configure and target the desired level of trust.

Objective: The present study was conducted to investigate the effectiveness of Sahajaoga and Mind Strengthening Yoga exercises on the anxiety test of female children with attention deficit hyperactivity disorder with gastrointestinal problems in Karaj. Method: The study is semi-experimental in the form of pre-test-post-test with the control group. . According to the input and output criteria, 30 people were selected and divided into 3 groups (two experimental groups and one control group). Data collection tool was a questionnaire for diagnosing hyperactivity disorder along with attention deficit disorder and Abolghasemi exam anxiety questionnaire. The interventions took place in eight sessions and the subjects were examined before and after the interventions with the test anxiety test. Results: The results of the present study, after collecting and analyzing the data by covariance analysis test, show that Sahajayoga and Mind Strengthening Yoga exercises significantly (at p <0.05) confirm the assumption that the sessions performed were effective. . In other words, after the intervention of Sahajayoga technique, about 98% and after the implementation of mind strengthening yoga, about 94% of the change in the dependent variable is due to the change in the independent variable. In fact, the Sahajaoga and Mind Strengthening Yoga training is effective in reducing the anxiety test of this group of children. Conclusion: The overall findings suggest that yoga-based training has a positive effect on reducing anxiety in children with attention deficit hyperactivity disorder and gastrointestinal problems. Therefore, it is recommended to use this method in medical centers to improve the anxiety and digestive problems of children with ADHD.

The purpose of the present research was to examine the effect of cognitive-behavioral stress management on health locus of control and resilience in patients with coronary artery disease. This research was quasi-experimental with pre-test, post-test and control group. The statistical population of this research consisted of all patients aged 40-65 years with coronary artery disease who were referred to Kasra Hospital in Tehran in 2019. The sample was 90 patients who were selected from the research population and assigned into the two experimental and control groups. Data were collected using the Multidimensional Health Locus of Control Scale and Resilience Scale. The research data were analyzed using Multivariate analysis of covariance (MANCOVA). The results showed that the cognitive-behavior stress management significantly increased internal health locus of control and resilience in the experimental group (P<0.01). Cognitive-behavioral stress management may lead to a change in one's self-awareness and abilities through cognitive challenge, cognitive error detection and thought replacement, which in turn can increases individual’s sense of containment and cognitive control.

Objective: some recent evidences have been recently achieved on the beneficial effects of mindfulness based on stress reduction on stress reduction and perceived anxiety and thus improve mental disorders caused by stress. Because women-headed households are one of the groups in the society that need to be studied because of the progressive problems they are experiencing as one of the most affected sections of society, the present study attempted to assess the efficacy of mindfulness-based stress reduction on improvement of the decreased perceived stress and symptoms of depression among this group. Methods: This quasi-experimental study with pretest-posttest approach and following-up included 400 women aged 25 to 50 years female-headed households covered by Ilam City Relief Committee. The population was randomly divided into control and experimental groups and the preserved stress and depression situations were assessed using the Cohen's Perceived Stress Scale and the Beck Depression Inventory II respectively. Mindfulness-based stress reduction was implemented as an 8-week training program and all subjects were reassessed after intervention completion. Results: The baseline characteristics of study subjects in two groups were similar. The mean preserved stress and depression scores improved both significantly in the experiment group after intervention as well as within the follow-up time, however the pointed changes were not revealed in control group. Conclusion: Mindfulness-based approach to stress reduction had a positive effect on perceived stress and depression symptoms in female-headed households

This qualitative, exploratory study investigated the learning opportunities and learning strategies afforded by technology-mediated tasks. In this study, a group of English as a Second Language (ESL) learners at an American university worked together to design and create a website for potential international students who are considering studying abroad in Alaska. Through the students’ post-task reflections, the following themes surfaced: “doing something authentic and meaningful,” “working together,” “learning English,” and “building confidence.” Within these themes, several types of language learning strategies consistently emerged through the data analysis: arranging and planning, self-evaluating, and cooperating

In recent years, educational studies have acknowledged that academic motivation is a powerful predictor of students' academic achievement. Goal orientation is one facet of academic motivation that concerns the reasons for which students pursue achievement activities. Using AGQ and R-SPQ-2F instruments, this study seeks to identify dominant achievement goal orientation held by Iranian EFL learners and examine the relationships between students' achievement goals, learning approaches, and academic achievement. The sample consisted of 80 EFL students majoring in English Literature and English Translation. The results of the data analysis indicated that the mastery goal is the dominant goal orientation adopted by learners. Afterward, performance-approach and performance-avoidance goals are respectively the achievement goal orientations adopted by Iranian EFL learners. Significant correlations were found between both mastery and performance-approach goals and deep approaches. Performance-avoidance goals were found to be significantly and positively related to surface approaches to learning. In addition, performance-approach goals were positively related to academic outcome, whereas, performance-avoidance goals were negatively related to academic achievement. There was no relationship between mastery goals and students' outcomes. The study also bears some theoretical and practical pedagogical implications regarding the importance of motivation and goal setting which will be offered and discussed in detail at the end of the study.

Consecutive interpreting (CI) requires a lot of parallel cognitive and affective processes, which are challenging for the interpreter who has to deal with them concurrently . This study focuses on the problems trainee interpreters encountered intheir CI sessions. An analysis of the strategies they used to weigh whether they have been successful in completing their task is also given. The sample of the study consists of 50 senior students of Translation enrolled in CI course (English-Arabic) in the Fall Semester 2018/2019 at the Translation Department at Yarmouk University, Jordan. The Source Text (ST), which was divided into one-minute period for each time, was given to students for interpretation and then the Target Text (TT) was recorded. Most of the challenges encountered by trainee-interpreters were linguistic problems, memory problems, note-taking and reproducing the ST into the TL. It is imperative therefore that interpreter training should be as effective as possible and interpreters shoulddevelop a series of skills and strategies such as chunking and joining, shadowing, anticipating, listening and recalling and paraphrasing that can be used to solve the problems encountered.
