Abstract: تجري هذه الدراسة تحليلا فيزيائيا لاصوات الابطال والاشرار في افلام الكارتون عبر فحص الخصائص الصوتية لكلا النوعين من الشخصيات. اعتمادا على الفرضية القائلة بان اصوات الاخيار والاشرار تمثل التوصيف الصوتي الشائع لكل من الشخص الخير والشخص الشرير في الحياة الواقعية. اظهرت الدراسات السابقة ان بصمة الصوت تحمل في طياتها العديد من المعلومات المتضمنة عن العمر والجنس والعرق والشخصية واللهجة والحالة الاجتماعية والمعاشية والعاطفية للمتكلم.عليه فان الدراسة الحالية تفحص الخصائص الفيزيائية المحددة لاصوات الابطال والاشرار وتنظر اذا ما كان هناك اي تشابه بين الاصوات ضمن النوع الواحد والتي بالتالي تسمح بفرز وتمييز الاخيار عن الاشرار. وبتطبيق نموذج تمييز الاشخاص المبني على اساس الصوت والذي يعتمد على النتائج التي توصلت لها الدراسات التي تبحث في مجال الادراك الاجتماعي، والتي اكدت على اننا كبشر عندما نقابل شخصا ما لاول مرة، فان هناك بعدين عالميين او شاملين للمعرفة الاجتماعية وهما : بعد الدفء وبعد الكفاءة او الاهلية. فيما يخص البعد الاول فانه يتضمن ميزات او صفات ترتبط بملاحظة او ادراك السريرة مثل الودية، الاستعداد للمساعدة، الاخلاص، الثقة، والاخلاق او الفضيلة. في حين ان البعد الثاني يشتمل على ميزات او صفات ترتبط بادراك القدرة او القابلية كالذكاء، المهارة، الابداع، الفعالية او الكفاية. وبعبارة اخرى، فان الناس يؤسسون انطباعات عن الاشخاص الغرباء اذا ما كانوا اصدقاء ام اعداء، واذا ما كان الشخص الغريب يمثل تهديدا او لا اولا، وهل لديه القدرة او القابلية على تنفيذ هذا التهديد ثانيا وذلك باستخدام استراتيجية اضرب او اهرب (الكر والفر). تقع الدراسة في ستة فصول. يقدم الفصل الاول تمهيدات الرسالة، ويعنى الفصل الثاني بتقديم نظرية بصمة الصوت وبعض المبادئ ذات العلاقة. في حين ان الفصل الثالث يسلط الضوء على العلامات والعناصر الواسمة في بصمة الصوت، اما الفصل الرابع فانه يعرض منهج البحث العلمي الذي طبقته الدراسة ويستعرض المواد الكارتونية والنظريات المتبناة وتسميات الشخصيات الكارتونية والبرامج الالكترونية او الحاسوبية المستخدمة وفرضيات البحث.اما الفصل الخامس فانه يعرض تحليلا لاصوات 44 شخصية بادءا بمتوسط ومعدل الانحراف للتردد الاساس (fundamental frequency) بالهيرتز(Hz)، ومتوسط ومعدل الانحراف لنطاق التردد الاساس بالسميتونز (semitones)، ثم يقوم بحساب قيم اول صفتين (formants) لثلاثة من اصوات العلة قي اللغة الانجليزية وهي صوت /ɪ/ وصوت /ə/ وصوت /ʊ/ . يتبع ذلك تحليلا بصريا للصور الطيفية (spectrograms) وتحويل فورييه السريع (fast fourier transform spectra) لكل من الابطال والاشرار. اما الفصل الخامس فيقدم الاستنتاجات والتوصيات والمقترحات.اثبتت الدراسة ان الاشرار البالغين ومن كلا الجنسين لديهم نطاق ترددي اوسع وتردد اساسي اوطا من الابطال. اما ما يخص تحليل صفات الصوت فقد اظهرت النتائج ان الابطال الذكور البالغين يميلون لاظهار قيم اعلى للصفة الاولى وقيم اوطئ للصفة الثانية، في حين ان قيم نفس الصفتين لاصوات الاشرار الذكور البالغين هي على العكس من ذلك. فئة الابطال الاناث البالغين تظهر قيم صفة اولى اعلى من الاشرار الاناث. باستثناء الصفة الاولى لصوت العلة /ɪ/ فان قيم الصفة الاولى للاشرار الاناث البالغين هي اعلى من قيم الاخيار. بالنسبة لفئة الاطفال، فان نتائج تحليل قيم فئة الاطفال الذكور الابطال والاشرار هي مشابهة لنتائج قيم الذكور البالغين الابطال والاشرار، في حين ان نتائج مقارنة قيم فئة الاطفال الاناث الابطال والاشرار تظهر نسخة معاكسة تماما لما جاء بنتائج مقارنة فئة الاناث الابطال والاشرار. ان نتائج الفحص البصري للصورة الطيفية ( التمثيل الصوري للصوت spectrograms ) اثبتت ان الاشرار يمتلكون نغمات او مناطق طاقة عليا اقوى من الاخيار مع استخدام صوت متوتر او مشدود (اجش او خشن). واخيرا، فان نتائج تحليل تحويل فورييه السريع ( FFT spectrums ) اثبتت ان الاشرار يظهرون اعلى قيم للذروة في منطقة 2500 - 3500 هيرتز. | This thesis studies heroes and villains' voices in anime by investigating the voice quality of each category acoustically, depending on the assumption that the voices of these two categories will represent the vocal stereotypes of good and bad guys in real life. Vocal stereotypes, that is, the consensual agreement among people in judging the other individual's personality attributions which is often inaccurate. Previous studies showed that voice quality carries many kinds of information about the speaker's age, sex, race, individual identity, dialect background, socio - economic status, personality, emotional state and other aspects. The study tries to investigate the specific acoustic characteristics of heroes and villains to find whether there are some similarities within each category which helps in discriminating heroes from villains. This is achieved by applying the voice - based person perception model which is introduced by Teshigawara in 2011 to study personality attributions depending on vocal features only. In this model Teshigawara introduced the two dimensions warmth and competence and their phonetic characteristics. People develop impressions on any stranger whether he is a friend or foe, whether he represents a threat or not using fight or flight strategy. This strategy is used by animals when an animal face another, it has to decide whether to fight or not after assessing the other animal's body size and aggression. The assessment process depends on the frequency code theory. Combining the voice - based person perception model with Ohala's frequency code theory which assumes that there is a cross species F0 function. A high F0 is indicates smallness, non threatening attitude and a desire for good will, whereas low F0 indicates largeness, threat and self confidence. By the assistant of the Cartesian coordinate which consist of two vertical and horizontal axes in mathematics. To achieve the above, this study investigates the voices of 44 characters' noise free portions using Praat software, starts with F0 means in Hz for both heroes and villains, F0 range in semitones, vowel formant frequencies specifically F1 and F2 for three English vowels namely, / ɪ /, / ə /, and / ʊ /, and applying visual spectrographic analysis for both heroes and villains with additional FFT spectra. The findings of this study are as follows : adult male and female villains have wider F0 ranges than adult heroes; adult male and female villains have lower mean F0s than those of heroes. Concerning formant frequency investigation, adult male heroes tend to show lower F1 and higher F2 in their speech, while adult male villains tend to express higher F1 and lower F2 in their voices. Female heroes record a higher F2 than female villains; except for F1 in / ɪ / vowel, adult female villains show that they have higher F1 values than heroes. With respect to child male heroes and villains, the results are similar to those of adult male heroes and villains, whereas child female heroes and villains results represent the opposite version of that of adult female heroes and villains. The results of the spectrographic analysis reveal that villains have strong upper harmonics and tend to express tense voice (i.e. harsh or creaky voice). Whereas, heroes have breathy or lax voice. Finally, the FFT spectra investigation show that villain voices have a peak at around 2500 - 3500 Hz.

Abstract: ان الترجمة المتعلقة بتحديد الجنس قد اصبحت من احدى التحديات التي يواجهها المترجمون عند التعامل مع اللغات التي تصنف الجنس بطرائق متعددة , وهذا يعود الى كون اللغات قد لا تختلف فقط بالطريقة التي تتبعها في تشفير فئة الجنس في الانظمة اللغوية المعجمية التابعة لها ولكن تختلف في ثقافاتهم ايضا والمتعلقة بمعنى الجنس. ان هذا الامر قابل للتطبيق في الترجمة بين اللغتين الانجليزية والعربية واللتين لا تختلفان فقط في طريقة تقديم الجنس في انظمتهما اللغوية ولكن ايضا في الطريقة التي يحملان فيها الاسماء ذات المحتوى الاجتماعي.ان الهدف من هذه الاطروحة هو اظهار الى اي مدى يمكن للايديولوجية اللغوية ان تلعب دورا في ترجمة طلبة الكليات العراقية للاسماء الانجليزية التي تشير الى المهن الى اللغة العربية. لقد تم اختبار خمسين طالبا وطالبة لغرض ترجمة ثلاثين جملة باللغة الانجليزية تحوي على اسماء مهن مختلفة مثل (دكتور) الى العربية. ان جنس كل كلمة غير محدد وغير مشار اليه كما في الجملة (هل استطيع التحدث معك يا دكتور)ان هذه الاطروحة تتكون من خمسة فصول : الفصل الاول يتضمن المقدمة والمشكلة والاهداف والفرضية والخطوات والحدود.الفصل الثاني يقوم بتعريف طريقة الترجمة وذلك عن طريق استكشاف الصلة بين الترجمة والتواصل والابداع والفلسفة والتطورات التي طرات على الترجمة والمعرفة والتعليم واكتساب اللغة.الفصل الثالث يعرض تاثير الجنس على اللغة من الناحية التي من خلالها يقوم الناس بتعريف او تحديد جنس الاشخاص وذلك من خلال نظريه وحركة المساواة وكذلك تحديد عدد من اللغات المنحازة او الحيادية كما ان هذا الفصل يشير الى علاقة الترجمة بالثقافة والجنس والهوية.الفصل الرابع يعرض الاجراءات وتحليل البيانات ويقوم بتفسير الطرائق والعينات وفضلا عن صحة الاختبار ودقته ويتطرق ايضا الى نتائج الدراسة ويستعرض بين طياته الاشكال والجداول التي تفسر جمع النتائج وماالذي تمثله هذه النتائج, بمعنى كيفية الحصول على النتيجة.الفصل الخامس يشتمل على الاستنتاجات والاقتراحات الخاصة بالدراسة. | Within the process of translation, Translators usually consider gender particularly when dealing with languages that pattern gender differently. Languages may not only differ greatly in the way they encode the category of gender in their lexical and grammatical systems but also in the expectations of their relevant cultures concerning what is meant by ' gender. This is applicable to translation between English and Arabic , which differ not only in how gender is rendered in their linguistic system, but also in the way they load nouns with social content. The aim of this thesis is to show the extent to which ideological considerations can play role when Iraqi college students translate English nouns referring occupations into Arabic. A test is given to fifty students of the Department of English at an advanced stage. The students are asked to translate thirty English sentences including occupational titles such as doctor’ into Arabic . The sex of each referent title is unknown, e.g. can I have a word with you , doctor?.In this thesis, chapter one presents the preliminaries that deal with the problem, the aims, the hypotheses, the procedures, the limits, and the significance of the study.Chapter two defines the process of translation exploring its connections to communication, creativity, philosophy, shifts of translation, cognition, teaching and language acquisition.Chapter three tackles the effect of sexism on language, in the sense of how people usually consider identifying the sex of individuals going through the feminist theory and movement also exploring some of the sexist languages around the world and which are gender biased and which are gender neutral. The chapter also investigates translation and gender, translation and culture, and translation and identity. Chapter four tackles the procedures as well as the data analysis. It explains the methods, the sample, the validity as well as the reliability of the test. Chapter five talks about the findings of the study. It contains tables and figures that explain how the findings of the study are collected and what they stand for, i.e. how is the outcome presented. Chapter six investigates the conclusions and the pedagogical implications of the study.

Abstract: ظهرت التداولية كمجال لاهتمام الباحثين مؤخرا" نظرا لاهميتها في مجال تعليم اللغات والدراسات الثقافية. ان تدريس التداولية للغة الاجنبية توفر للطلاب فرصة ليصحبوا متكلمين بشكل افضل ويتجنبوا سوء التواصل. ان الدراسة الحالية تحاول التركيز على ضرورة تدريس التداولية الانكليزية في الصفوف العراقية لتعليم اللغة الانكليزية. تستند هذه الدراسة على اداتين رئيستين هما : استبيان لاساتذة اللغة الانكليزية واختبار اكمال الحوار المتعدد. وقد صمم الاستبيان لغرض جمع اراء اساتذة الجامعة عن اهمية التداولية في التعليم, واهمال التداولية, ومستوى قدرة التداولية للمتعلمين, وتنشيط التداولية في الصف, والفرص المتوفرة لاكتساب القدرة التداولية خارج الصف, وتدريس الادب والتداولية, والوسائل التعليمية لتدريس التداولية. اما الاختبار فقد صمم لتقييم القدرة التداولية لدى المتعلمين العراقيين للغة الانكليزية في اربعة من الافعال الخطابية وهي : الاعتذار والطلب والرد على الاطراء والرفض. تقع الدراسة في خمسة فصول, الفصل الاول التمهيدي يتناول مشكلة البحث والنظريات والهدف وحدود الدراسة وفائدتها العلمية والتربوية واجراءات تطبيق الاستبيان والتحليل والوسائل الاحصائية.اما الفصل الثاني والثالث فيشملان الاطار النظري للبحث اذ يتناولان التداولية والتواصل بين الثقافات وكيفية تدريس التداولية واهميتها للطالب والمعلم. والفصل الرابع يقع في جزاين : يشمل الجزء الاول منه اجراءات البحث وادواته المستعملة والصدق والثبات وعينة البحث والوسائل الاحصائية المتبعة في تحقيق النتائج .اما الجزء الثاني منه فيشمل تحليل النتائج. اما الفصل الخامس وهو الاخير يتعامل مع نتائج البحث المستخرجة من الجزء العملي. وقدم الباحث بعض التوصيات واقترح بعض الافكار والنقاط لغرض دراستها مستقبلا . اهم ما توصلت اليه الدراسة الحالية بعد تحليل النتائج هو ان اداء الطلاب كان ضعيفا في الاختبار مقارنة مع قدراتهم اللغوية العالية المحتملة. فضلا عن ذلك, يتفق كثير من الاساتذة بان التداولية يجب ان تحظى باهتمام اكثر في صفوف الادب واللغة اذ ان فوائدها تنعكس على ادراك الافضل للغة في التواصل الحقيقي والعمل الادبي. على الرغم من ان هناك العديد من التحديات التي سببت في اهمال التداولية, لا يزال هناك كثير من الحلول ليتم تطبيقها بوساطة الاساتذة او المتعلمين انفسهم لتطوير كفاءتهم التداولية | Recently, pragmatics appeared to be a field of interest for many researchers for its importance in the field of language teaching and cross - cultural studies. Studying the foreign language pragmatics provides learners with opportunities to become better communicators and avoid probable breakdowns. The present research attempts to focus on the necessity of teaching pragmatics in Iraqi EFL classrooms. There are two tools used in the research : the questionnaire and multiple discourse completion test (MDCT). The questionnaire was designed to collect data from university teachers’ opinion on pedagogic importance of pragmatics, pragmatic neglect, learners’ level of pragmatic competence, activating pragmatics in the class, opportunities for acquiring pragmatics out of the class, literature and pragmatics, and teaching aids for teaching pragmatics. MDCT was designed for assessing Iraqi EFL learners’ pragmatic performance in four most common speech acts as apology, request, compliment response, and refusal. The research consists of five chapters. Chapter one presents preliminaries of the research as the research problem, hypotheses, objectives, design, procedure, value and scope. Chapter two and chapter three provide the theoretical background of the research. These chapters deal with pragmatics and cross - cultural communication, teaching pragmatics, pragmatic instruction, teachers’ role, learners’ role, and teaching aids. Chapter four holds two parts. The first part sets the scene which encapsulates research method as the procedures, research tools, sampling, validity, reliability, and statistical means used in finding out the results of the research. The second part discusses the research results. Finally, chapter five displays the conclusions, and some possible recommendations has been given by the researcher in addition to some suggestion for further research. There are some main conclusions drawn from analysis of the results. The learners’ performance in the test indicates that they have low pragmatic competence as compared to their supposedly high linguistic knowledge. In addition, most teachers agree that pragmatics needs to receive more attention in literature and language classes as its advantages will be reflected in better understanding the language in a real communication or a literary work. Though there are a number of challenges that cause neglecting such an important aspect of linguistics, there are still many solutions that can be adopted by the teachers or the learners themselves for improving their pragmatic ability

Abstract: يعد كلا من مفهومي الحدث الحركي للفعل والفضاء الذهني ظاهرتين مركزيتين في اصول علم اللغة الادراكي، لانهما من اساسيات التجربة والادراك في حياة الفرد اليومية. ومن الفرضيات اللغوية ان كل لغة تختلف عن اللغات الاخرى في اساليب التعبير عن الحركة، وهذا يؤكد ان مفهوم الحدث الحركي يخضع للتفكير الفضائي للانسان، والى التنوع اللغوي الذي تظهره اللغات، فضلا عن ان تركيب الحدث الحركي الاساسي له تمثيل وصورة ذهنية متمركزة داخل العقل البشري، وبمعنى اخر ان الاطار الادراكي لمعنى المفاهيم الحركية المجردة للفعل تكون متمعجمة في اغلب لغات العالم. اما الفضاء فهو مفهوم لغوي مركب يكون مبنيا على التداخل بين اللغة والادراك، وقد تعاملت المداخل السابقة مع الفضاء بكونه موقعا فيزيائيا للكيان المتحرك، لكن علم اللغة الادراكي ينظر الى الفضاء بوصفه تمثيلا ذهنيا - فيزيائيا للكيان، وبذلك يكون الفضاء داخل البشر وحوله.ومن خلال نظريته، يقسم (تالمي) اللغات الى قسمين : اللغات التي تعتمد على الفعل في الافصاح عن الحركة، واللغات التي تعتمد على لواحق الفعل في الافصاح عن الحركة، وعلى وفق هذه النظرية يتكون الحدث الحركي الاساسي من الجسم المتحرك والموقع الذي تنتهي اليه حركة الجسم والمسار والحركة التي تتمثل باحد افعال الحركة، فضلا عن ان الحدث الحركي يكون مقيدا بالتركيب اللغوي السطحي (النحوي)، والتركيب الدلالي، والتركيب الادراكي المتجسد في الذهن البشري.وتهدف الرسالة الى دراسة اساليب التعبير عن الحدث الحركي وطرق ادراكه عبر الفضاء في اللغتين الانجليزية والعربية، وتتناول الدراسة افعال الحركة والحدث الحركي في هاتين اللغتين عبر مدخل ادراكي يحاول اثارة الاسئلة التالية : هل يشكل المتحدث المعنى الفضائي بطريقة متشابهة او متباينة؟ وهل هناك متشابهات حقيقية بين اللغة الانجليزية واللغة العربية فيما يتعلق بادراك الحدث الحركي؟ وهل تعبر اللغة الانجليزية عن الحدث الحركي عن طريق الفعل او لواحق الفعل، او بالطريقتين معا؟ وهل تعد اللغة العربية من اللغات التي تعتمد على الفعل في التعبير عن الحركة؟ وكيف تتباين اللغات التي تعتمد على لواحق الفعل عن تلك اللغات التي تعتمد على الفعل في التعبير عن الحركة؟وكي نجيب عن هذه الاسئلة اتبعت الدراسة بعض الاجراءات المنهجية وهي : جمع العينات اللغوية الخاصة باللغة الانجليزية والعربية، وتحليل عملية الادراك وانماط المعجمة لافعال الحركة في هاتين اللغتين، ومحاولة التحلليل الادراكي لافعال الحركة والحدث الحركي في اللغتين الانجليزية والعربية، ثم التوصل الى استنتاجات حول كيفية تمعجم الحدث الحركي ادراكيا في هاتين اللغتين.وعلى ضوء تحليل العينات توصلت الدراسة الى بعض الاستنتاجات اهمها : ان الحدث الحركي في هاتين اللغتين يتكون من الجسم المتحرك والموقع الذي تنتهي اليه حركة الجسم، والمسار، والحركة، كما ان هاتين اللغتين تستطيعان التعبير عن الحدث الحركي من دون المسار والموقع الذي تنتهي اليه حركة الجسم، ويؤكد هذا ان المسار والموقع الذي تنتهي اليه حركة مكونان غير اساسيين في تركيب وادراك الحدث الحركي في هاتيين اللغتين.اما بالنسبة الى الاختلافات الكامنة بين اللغتين، فنرى ان اللغة الانجليزية تستطيع التعبير عن الحدث الحركي بواسطة الفعل ولواحق الفعل، بينما تكتفي اللغة العربية بالتعبير عن الحدث الحركي بواسطة الفعل فقط. ويتكون المسار في اللغة الانجليزية من ثلاث مكونات هي : الناقل، والمشكل، والمؤشر، بينما يتالف المسارفي اللغة العربية من الناقل فقط. ان اللغة العربية لاتمعجم ظاهرة التشخيص بالفعل عندما يتبادل المشتركون في حدث الفعل نفسه من اجل القيام بهذا الحدث، وكذلك ظاهرة التكافؤ بالنسبة لافعال الحركة والتي يتحدد من خلالها الفاعل النحوي للفعل والمفعول به وامكانية جعل المفعول به يحل محل الفاعل والفاعل محل المفعول به ليعبر عن الحدث الحركي من دون التغير في المعنى | The Motion event and space are two central phenomena in cognitive linguistics because they are primary in human experience and cognition. Linguistically speaking, the world's languages differ in the way they express the Motion event. The Motion event is subject to human spatial thinking and to crosslinguistic variations. In addition, the construction of a basic Motion event has a mental structure in the human mind, i.e. it provides a cognitive framework to the meaning of abstract domains, and it is lexicalised in all the world's languages. Space is a complex linguistic domain based on the interaction between language and cognition. In the previous approaches to linguistics, space is treated as the physical location of an entity (e.g. X locates to Z), but, in CL, space is considered a mental representation; that is, in addition to being physical, space always presents round and inside humans. Talmy’s (2000b) Lexicalisation Patterns theory divides languages into two systems : verb - framed languages and satellite - framed languages. The verb - framed languages express the Motion event through the Path that appears in the verb root, while the satellite - framed system expresses the Motion event via the Path that appears in the satellite. According to this theory, the basic Motion event consists of the Figure, the Ground, the Path, and the Motion. This basic Motion event is determined by the surface structure (the linguistic or grammatical structure) and the semantic structure. Furthermore, it has a cognitive structure in the human mind. The present study aims at investigating how the Motion event is expressed and conceptualised in standard English and standard Arabic along space. This thesis studies the Motion verbs and the Motion event in these two languages from a cognitive perspective throughout arising questions like : do users of these language construct spatial meaning in a similar or different way?, are there real similarities between English and Arabic as far as the conceptualisation of the Motion event is concerned?, Is English a satellite - framed or a verb - framed language, or both?, Is Arabic a verb - framed language?, and how do satellite - framed languages differ from verb - framed languages in the expression and construction of the Motion event?. To answer such questions, the study follows certain procedures such as collecting data, analysing conceptualisation and lexicalisation patterns of Motion verbs in the two languages, analysing cognitively the Motion verbs and the Motion event in English and Arabic, drawing conclusions on how these two languages lexicalise the Motion events.Throughout the analysis of the data of English and Arabic, the study arrives at some conclusions like : the basic Motion event both in English and Arabic consists of four components, the Figure, the Ground, the Path, and the Motion, both English and Arabic can express the Motion event without a Path and Ground; this ascertains the fact that the Path and Ground are not necessary components in the construction and conceptualisation of the Motion event in the two languages, English is both a satellite - framed language and a verb - framed language, while Arabic is a verb - framed language, the Path in English is of three main components, the Vector, the Conformation, and the Deictic, whereas in Arabic, it consists of the Vector only, the material of the Co - event in English and Arabic can conflate onto the two deep verbs BELOC and MOVE and onto certain mid - level verbs, Arabic neither lexicalises the parameter of personation in which two participants involved in certain actions of Motion nor the focusing property of a verb, valence, etc

Abstract: Teaching listening comprehension plays a vital role in second language learning in which it is the basis for the future acquisition of other language skills : speaking , reading and writing. In spite of its significant role, listening skill has long been allocated slight attention in research, teaching, and assessment. The main goal of this investigation is to shed light on the effect of listening skill as a way to improve and achieve success in oral communication. The present study aims to investigate teachers' abilities in teaching listening skill through piloting three main instruments : First, by exploring teachers' productivity in teaching listening through conducting questionnaire for the teachers of English at the secondary stage in Basra governorate. Second , conducting teachers' questionnaire which was supported by the observation checklist so as to have a close look at the teachers' abilities in using the proper techniques for teaching listening skill. Third, as a supplementary instrument_ a focused interview was carried out with the supervisors of English in Basra Governorate concerning integration of teaching listening skill with teaching English in everyday classroom. Particularly, these supervisors have ample insights on teachers' efficiency in teaching listening skill through their continuing observations of the teachers of English throughout the whole academic year. The study consists of five chapters. Chapter one is an outline of the study; it tackles the problem, hypotheses, objectives, value, scope and procedures of the study. Chapter two comprises basic concepts concerning listening comprehension : importance, negligence, a historical overview of teaching listening, factors affecting listening skill, types of listening and the current situation of teaching listening in Iraq. Chapter three deals with the psychology of listening competence : cognitive processes and the strategies that can be used to enhance listening comprehension. Chapter four has two dimensions : the first dimension shows the research procedures followed to investigate teachers' abilities in teaching listening including the research instruments, sampling, validity, reliability, and the statistical means used in finding out the results of the study. The second one demonstrates the practical investigations and the analysis of the research instruments. Chapter five offers the conclusions of the study which are related to the theoretical and the practical parts accompanied with brief educational recommendations for teachers of English and the educational authority at the Ministry of Education. On the basis of the outcomes obtained from the teachers' questionnaire, the observation checklist and the focused interview with the supervisors of English, the study shows that most of the secondary teachers of English lack adequate knowledge, experience and time concerning teaching listening skill in the prescribed curricula. Besides, there is a significant difference between trained teachers and untrained teachers in teaching listening skill which shows the effect of training courses in increasing teachers' abilities in teaching English. Moreover, the research survey sheds light on the causes that contribute to teachers' inadequacy in teaching listening such as insufficient time for teaching listening, the necessity for special labs for teaching English and the inadequate use of the audio aids in teaching listening skill.

Abstract: In this study, two types of Schiff base were prepared as ligands L1, L2, by reaction of an equal number of moles of tris(hydroxymethyl) methyl amine with salysildehyde and vanillin in a methanolL1 : ((E) - 2 - ((2 - hydroxybenzylidene) amino) - 2 - (hydroxymethyl) propane - 1,3 - diol) L2 : ((E) - 2 - ((4 - hydroxy - 3 - methoxybenzylidene) amino) - 2 - (hydroxymethyl) propane - 1,3 - diol).The Cu(II) and Mo(VI) complexes were prepared to produce the : - A1 : tetrakis(μ3 - 2 - {[1,1 - bis(hydroxymethyl) - 2 - oxidoethyl] iminomethyl} - phenolato) tetrakis [aqua copper(II)].A2 : tetrakis(μ3 - 2 - {[1,1 - bis(hydroxymethyl) - 2 - oxidoethyl] iminomethyl} - 2 - meth - oxy} - phenolato) tetrakis [aqua copper(II)].B1 : (E) - 2 - methyl - 2 - ((2 - ((methyl(l1 - oxidanyl) dioxomolybdenio) oxy) benzylidene) amino) propane - 1,3 - diol).B2 : (E) - 2 - ((4 - hydroxy - 3 - ((methyl(l1 - oxidanyl) dioxomolybdenio) (methylene) - l4 - oxidanyl) benzylidene) amino) - 2 - methyl) propane - 1,3 - diol).The ligands and complexes were characterized by Fouries transformer infrared FTIR, UV and NMR techniques.All these techniques insisted that the ligands and their complexes were prepared successfully.On the other hand, the four complexes A1, B1, A2 and B2 were evaluated as corrosion inhibitors against a corrosive environment of 0.1M of hydrochloric acid at constant temperature of 25°C and different concentration for each one of the above complexesIIrange (10 - 50) ppm and it has been found that the efficiency of inhibition at a temperature 25℃ are not highly efficient, the KI was added in order to increase the efficiency of these inhibitors values to these inhibitors.The inhibition efficiency for all inhibitors was increased in presence of KI compared with the absence of it.On the other hand, the complexes of copper i.e., A1 and A2 have higher efficiency than molybdenum complexes i.e. (B1 and B2) this can be attributed to the ability of copper ion (II) to donate the electron density to the ligand by back donation competence these behaviour compared with molybdenum ion (VI) that has not the ability that present in copper ion, Also studied the effect of concentration of the inhibitor prepared in other temperatures change separately and these grades are within the range (35 - 55) ℃ has been observed that efficiency does not increase either the existence of KI with the inhibitor, or without, but the decreasing efficiency with increasing temperature, means that the inhibitor adsorbed physically on carbon steel alloy.The functions thermodynamic adsorption such as free energy, enthalpy and entropy were studies depending on the adsorbent layer θ on the surface of the carbon steel alloy. The data was shown all the complexes are subject to model for Langmuir adsorption was shows the free energy negative values means that the interaction is spontaneous and notes total increasing of the temperature less than the negative value of the free energy leading to towards the is non - spontaneous. The negative values of enthalpy means that the interaction is exothermic, the negative value of the entropy of adsorption ΔSads and gradually moving toward positive values with a high temperature means that the random was less in high temperature. Also the kinetics of corrosion in the absence and present of the inhibitor was studied with KI in (0.1) M HCl. The activation energy and other thermodynamic function such as enthalpy and entropy and free energy was shown that the higher activation energy in presence inhibitor and it was higher in presence of KI with inhibitor. This is an indication that the interaction of corrosion is small in the presence of these inhibitors.

Abstract: The thesis involves three parts : The first part included synthesis eight new Azo dyes,derived of Procaine and Metoclpramide : LR1R = 3 - [ ( Procaine ) azo ] - 2 - hydroxyl indoleLR2R = 2 - [ ( Procaine ) azo ] - 4,5 - diphenyl ImidazolLR3R = 2 - [ ( Procaine ) azo ] - 3 - PhenylephrineLR4R = 2 - [ ( Procaine ) azo ] Imidazol, L5 = 2 - [ ( Metoclopramide ) azo ] Imidazol,LR6R = 2 - [ ( Metocopramide ) azo ] 3 - PhenylephrineLR7R = 3 - [( Metoclopramide ) azo ] 2 - hydroxyl indoleLR8R= 2 - [( Metoclopramide ) azo ] - 4,5 - diphenyl ImidazolThey have been described by C.H.N. and Visible spectroscopic spectra and the functional groups were characterized by I.R technique like azo group of (1558.48 , 1512.19 ,1581.63 , 1508.12 , 1521.84 , 1529.55 , 1517.98 , 1533.14 ) cm - P 1 P for azo dyes (LR1R LR2R , LR3R , LR4R , LR5R , LR6R , LR7R , LR8R) respectively The Acid - Base properties were also studied spectrophotometric using buffer solutions of pH values of (0.67 - 12) in the visible region, From the spectra obtained the protonation an ionization constants of azo dyes were determined by using Half - Height method ,the isopiestic point were also established ,which indicated the suggested mechanism for the ionization and protonation steps.The effect of solvents of different polarities was also studied on the spectra shift in the visible region. It was found that linearity relation between the dielectric constants of solvents and λRmaxR this denotes the dielectric constants at the mediumis the main factor governing the band shift, except for (LR6R) azo dye which give little deviation from linearity . The second part concerns with the ability of azo dye (LR8R) for forming complex with Cu(II) , The optimum conditions for forming stable azo dye - complex were studied like pH effect , kind of buffer solution , time effect and sequence of addition of reagents by aid molar ratios method and Continuous variation method It was found that stable complex was obtained with stoichiometry of 1 : 2 ( M : L ) From calibration curve of (L8) complex , : Sandell sensitivity 2.492× 10 - 3 μg cm - 2, Detection limit 0.00977 μg ml - 1, Standard deviation 0.00193, Correlation coefficient 0.994 , molar absorbitivity coefficient 2.547×104 L mol - 1cm - 1 , specific absorbtivity 0.4012 ml g - 1cm - 1 and obeyness of Beer's law linearity up to 3.20 ppm The effect the interference of some important cations and anions of concentration (1 - fold, 5 - fold and 10 - fold ), the stability of this complex was showed through determination of their conformation constants (stability constants) by use the corresponding solution method ,by aid of using half value method .this complex had been characterized by (FT - IR) according to the different of shift relativity abundance of same active groups bundle complex comparison with privately dyes ; the azo group ( - N=N - ) and (C=N) groups.,the percentage to metal (Cu) in the complex determine by using of result Atomic Absorption Spectroscopy where found approximate the same between theoretical and measurement.The third part : involved solvent extraction of Copper(II) ions from its aqueous solution by using L8 to organic solution. This study include limitation of optimum conditions for complex formation of highest observed absorbance of λmax at complex : such as (pHex=7) ,ions concentration Copper(II) 15μg effect shaking time of two immiscible phase 15 min .the distribution ratio (D*).and extraction percentage (%E) were determination.Organic solvent effect study appeared there is not any linear relation between dielectric constant (D) of organic solvents and distribution ratio (D*) that’s mean there is not any effect for polarity of organic solvent on extraction method but there is an effect for organic solvent structure which is participate in the structure of ion pair complex extracted by formation tight ion pair or loose ion pair as well experiment result illustrate chloroform organic solvent it was the best organic solvent in extraction .Thermodynamic study include Temperature effect on extraction efficiency the experimental results demonstrate the reaction was exothermic for Copper(II) with organic reagent (LR8R) endothermic reaction , after calculation thermodynamic data ΔHRexR , ΔGRexR , ΔSRex Rshow entropy values was high that is mean complexion reaction is entropic in region
