This paper focuses on the most prominent theta roles used in the Sindhi language. The study attempts to answer to the research question, ‘How are theta roles prominently used in the Sindhi language?’ The data come from the young native Sindhi speakers. Each verb phrase in the data is examined with the help of Carnie’s (2007) ‘Theta Roles and Thematic Relations’ in order to find the prominent theta roles in the Sindhi language. The study finds six prominent theta roles in Sindhi; namely, agent, theme, beneficiary, recipient, goal and locative. According to the findings of Rappaport Hovav (2007), the hierarchy of the theta roles in English is: Agent> Recipient>Experiencer/Goal>Instrument>Patient/Theme>Place; while, the hierarchy of the prominent theta roles in the Sindhi language is: agent>theme>beneficiary>recipient> locative>goal. This finding is not, however, definitive, i.e. broader studies are to be carried out to find the precise hierarchy of the theta roles in Sindhi.

Concerns over the phony nature of textbooks and artificiality of their contents in reflecting authentic language have been raised by a number of researchers. It has been argued that many language teaching programs result in the failure of learners of English to successfully communicate in the target language. The problem with these programs is that there is no general agreement about the success of these materials in developing the pragmatic competence necessary for interlocutors’ mutually intelligible communication[D1] . Hence, this study explored communicated requests for nonverbal/verbal goods and services (RNGS/RVGS) in the dialogues of 5 textbooks and 8 English movies. The utterances of the textbooks and movies were evaluated on six criteria deriving from research on speech act theory, politeness, and conversation analysis. These included whether the textbooks discussed second pair parts, the forms of requests, the context of request occurrence, the nature of the devices through which the requests are mitigated, and multi-turn request forms. The results of the analysis revealed that, except for re-requests and dispreferred responses of RNGS,textbooks’ strategies including forms, face, contexts of RVGS, and strategies of RNGSwere not realized through adequate examples compared to their variants in movies.Most importantly,except for bald on record, internal mitigators of RVGS, external mitigators, and direct and indirect forms of RNGS, the other request strategies in the textbooks showed less variety than those of their counterparts in the movies. Internally mitigated RVGS were the onlystrategies variouslyexploited in the textbooks.The findings revealed that textbook designers should improve their instructional materials by incorporatingmore accurate samples of communicated requests in their future textbooks.

This experimental study attempts to see whether incorporating supplemental podcasts into the blended module of second language (L2) vocabulary teaching and learning leads to better learning outcomes in comparison with other common teaching and learning methods as self-study and conventional. To that end, undergraduate students from Ahvaz Jundishapur University of Medical Sciences were summoned up via an announcement to take part in the study. Volunteers were homogenized via Vocabulary Levels Test (VLT) and were then randomly divided into three groups to learn English vocabulary items via three different scenarios during 32 sessions. The collected data from the participants’ answers to the attitude questionnaire and interview as well as the data from assessing their performance throughout the course were analyzed both descriptively and inferentially. The analysis of the data revealed that the podcast-mediated blended L2 learning scenario appeared as the most successful scenario in L2 vocabulary learning. Consequently, it could be concluded that providing miscellaneous practicing opportunities for students would facilitate learning process and contribute to learning improvement.

The present study was an attempt to investigate the significance of verbalization and teaching the concepts of listening on the development of listening performance among Iranian EFL learners. To do so, an experimental study was designed in which the participants were sixty pre-intermediate learners selected based on the results of their performance on a standard version of Oxford Placement Test (OPT). The participants were divided into two experimental groups. The learners in experimental group I (Systemic Theoretical Instruction- Explanation and Materialization (STI-EM), were exposed to materialized tools which consisted of presenting the target concept in charts accompanied by the examples and related strategies to extract the concept, while Group II students (Systemic Theoretical Instruction- Explanation, Materialization, and Verbalization (STI-EMV), enjoyed materialized tools as well as collaborative verbalization. The learners in both groups went through pre-test, intervention, and post-test. The collected data were analyzed through employing analysis of covariance (ANCOVA). The results indicated that the group which practiced collaborative verbalization in L1 outperformed the one which was just mediated by teacher's oral explanation and materialized objects

در سایه توسعه مفهوم فراگفتمان، امروزه به این درک رسیده ایم که نوشتار علمی صرفا به داد و ستد معانی محتوایی نمی پردازد: آنچه که از طریق گفتمان علمی داد و ستد می شود به شدت با تبادل معانی اجتماعی و بین فردی در پیوند است. بر اساس این دیدگاه، مطالعه حاضر با استفاده از الگوی ارائه شده توسط تنگ و جان در سال 1999 به بررسی ویژگیهای ذکر خویش در کتب علمی نوشته شده توسط استفان هاوکینگ پرداخته است. یافته های این تحقیق نشان می دهد که از میان نقش های شناسایی شده توسط تنگ و جان، نقش بازنماگر پر تکرارترین نقش ذکر خود در گفتمان استفات هاوکینگ را تشکیل می دهد. بر اساس تعریف ارائه شده از این نقش چنین نتیجه گیری شده است که این دانشمند ، پذیرش اجتماعی استدلال های خویش را به عنوان یکی از مهمترین ابزارهای متقاعد نمودن خوانندگان خویش تلقی می نماید.

The study of linguistic devices variously referred to as stance expressions is one of the best means by which the relationship between the writer, the reader, and propositional meaning could be examined. This paper looks at a particular structural group of lexical bundles encoding stance expressions. These are bundles starting with an anticipatory it followed by is, a predicative adjective and finally ending with infinitival to or complementizer that (e.g. it is important to, it is possible that). The use of these bundles is compared in three corpora of research articles, doctoral dissertations, and master theses in the discipline of applied linguistics to explore possible generic variations and identify possible differences between published students writing. Using Hewings and Hewings's functional typology of interpersonal roles of it clauses (2002), this group of bundles is found to have three stance expressions of hedging, marking attitude, and stressing emphasis. The major difference is discovered to be between students' genres and research articles, with the former drawing less in their expression of interpersonal meanings. The differences are accounted for by referring to generic expectations, and students' growing disciplinary identity. The findings of the study have some implications for academic writing.
