This thesis is entitled “Fostering collective teacher efficacy through values-based leadership in Ethiopian institutions of higher education”, which is delimited to the private universities. The main question was “What constitutes/determines the institutionalisation of values-based leadership (VBL) to foster collective teacher efficacy (CTE) in the context of Ethiopian private universities (EPrUs)?” The sub-questions were: 1) what does the current state of CTE and its perceived outcomes look like in EPrUs? 2) What sets of behaviours are desired to institutionalise VBL so as to foster CTE in EPrUs? 3) What are the institutional contexts required to institutionalise VBL so as to foster CTE in EPrUs? In addressing these issues, academic leaders, students and teachers from EPrUs participated in the study. As methods of data gathering both the survey method and interviews were used. Results revealed that CTE is not high enough in EPrUs and hence it needs to be fostered so as to bring the desired change in students’ learning. To foster this, institutionalisation of VBL is required that involves two inter-related aspects. The first one is about institutionalising desired values (behaviours), which are linked to the academic leaders’ yearning for positive sets of values and the teachers’ moral contract to their professional values. To this effect, the positive sets of values that academic leaders should yearn for and the sets of values that teachers should espouse as their professional values are explored. The commonalities between these values are also described and how these would be institutionalised is suggested. The values include integrity and trustworthiness, humility/selflessness, compassion and sense of gratitude, accountability and self-discipline, sense of collaboration and teamwork, and envisioning in leadership as the driving force. The second aspect is about institutionalising the contexts conducive to foster CTE and VBL support behaviours. The need to institutionalise those behaviours and contexts arise out of the perceived leadership gap (between what the teachers believe are the leadership priorities of the leaders and the behaviours they actually see in the leaders). This gap has been linked to CTE, and hence a model has been developed that would foster this efficacy. / Educational Leadership and Management / D. Ed. (Educational Management)

Access to safe water and improved sanitation remains threatened by the ever increasing demand in urbanised cities of the world. Adequate management of this problem could not be achieved through technical and regulatory methods alone. A human values-based education approach, namely the Human Values Water, Sanitation and Hygiene Education (HVWSHE) programme, was considered a suitable intervention strategy to bring about the desired changes in attitude and behaviour by the water users. This research involves an empirical case study approach that explores the experiences of Laotian teachers as adult learners of the HVWSHE intervention as well as a literature study on adult education, adult learning facilitation, human values-based education and teacher beliefs. Focus group meetings, lesson observations, participant observation, field notes and a researcher journal was used to collect data. This study revealed that the HVWSHE training programme had a positive effect on the adult learners’ attitude and behaviour towards a better water-use and sanitation-friendly ethic. / Educational Studies / M.

Cette thèse contribue à l'état actuel des connaissances sur la compatibilité des nouveaux bâtiments avec les environnements urbains historiques. Elle suit un mode de présentation classique: Introduction, Revue de Littérature, Méthodologie, Résultats, Discussion et Conclusion. Le problème étudié est le manque d'orientation pour intégrer les processus de développement et de sauvegarde dans les contextes établis. La littérature récente révèle que les règles de préservation, aussi appelées normes et lignes directrices, ne peuvent pas garantir une relation compatible entre une intervention et son milieu. La pensée contemporaine dans le domaine de la conservation et de la gestion du patrimoine invite donc l’exploration d'autres moyens pour lier la nouvelle architecture à l'ancienne. Ainsi, le présent projet de recherche explore une approche alternative aux règles de préservation en vue d’atteindre le but de nouveaux bâtiments compatibles et d’améliorer la prise de décision fondée sur les valeurs. Pour produire des résultats spécifiques et convaincants, un cas a été sélectionné. Celui-ci est une ville dans la région du Golfe Arabe : la Ville de Koweït. Le résultat principal est le développement d’une approche, mise en œuvre en posant des questions approfondies sur le lieu, la conception et la construction des nouveaux bâtiments. Les questions suggérées dans la thèse mettent l’accent sur les valeurs patrimoniales et les choix de conception afin de permettre un changement réfléchi au sein des environnements urbains historiques. Elles aident aussi à évaluer les nouvelles propositions de projets au cas par cas. Pour démontrer comment cette approche pourrait être présentée et utilisée par les requérants et les évaluateurs, un modèle théorique est proposé. Ce modèle a ensuite été discuté avec des professionnels locaux et internationaux qui ont identifié ses forces et ses limites. En conclusion, l’ensemble des résultats montre que la mise à disposition de règles et / ou de questions approfondies n’est pas une solution satisfaisante puisqu’il y a d'autres enjeux importants qui devraient être abordés: comment appliquer l'orientation efficacement une fois qu’elle a été créée, comment développer la compétence liée à la prise de décision fondée sur les valeurs et comment insérer la conservation du patrimoine dans la mentalité du gouvernement local et des communautés. Lorsque ces enjeux seront traités, le patrimoine pourra devenir partie intégrante du processus de planification, ce qui est le but ultime. Enfin, cinq axes de recherche sont recommandés pour poursuivre l’exploration des idées introduites dans cette étude. / This thesis contributes to the current state of knowledge on the compatibility of new buildings with historic urban environments. It follows a classic mode of presentation: Introduction, Literature Review, Methodology, Research Findings, Discussion and Conclusion. The problem under study is insufficient guidance to integrate the processes of development and safeguarding in established contexts. Recent literature reveals that preservation rules, also known as standards and design guidelines, cannot guarantee a compatible relationship between an intervention and its surroundings. Contemporary thinking in the field of heritage conservation and management, therefore, urges the exploration of other means for relating new architecture to old. Accordingly, the present research project explores an alternative approach to preservation rules with a view to achieving the goal of compatible new buildings and improving values-based decision-making. To generate specific and convincing results, a case study was selected. The latter is a city in the Arabian Gulf region: Kuwait City. The main research finding is the development of an approach, implemented by asking probing questions about the location, design and construction of new buildings. The questions suggested in the thesis put emphasis on heritage values and design options to enable thoughtful change in historic urban environments. They also help assess new project proposals on a case-by-case basis. To demonstrate how this approach might be presented to, and used by, applicants and evaluators, a theoretical model is proposed. This model was later discussed with local and international practitioners who identified its strengths and limitations. In conclusion, the overall research findings show that the provision of rules and/or probing questions is not a satisfactory solution because there are other important issues that must be addressed: how to effectively apply guidance once it has been created, how to develop the skill of values-based decision-making and how to embed heritage conservation in the mentality of local government and communities. When actions will be taken to deal with these issues, heritage could become a part of the planning process, which is the ultimate goal. Lastly, five research directions are recommended to further explore the ideas introduced in this study. / تساهم هذه الأطروحة في زيادة المعرفة المعاصرة بخصوص توافق المباني الجديدة مع المناطق المعمارية التراثية. إنها تتبع أسلوب النمط الكلاسيكي لعرض الأفكار: مقدمة، مراجعة الدراسات المعنية، جمع وتحليل المعلومات، نتائج، مناقشة، وخاتمة. فهي تتناول مشكلة نقص التوجيه لدمج عمليات التنمية والحماية في المناطق المعنية. الدراسات الأخيرة تشير إلى أن قوانين الحفاظ، المعروفة أيضا" بالمعايير والمبادئ التوجيهية للتصميم، لا تستطيع أن تضمن وجود علاقة توافق بين التدخل المعماري والمكان المحيط به. لذا التفكير المعاصر في مجال الحفاظ على التراث وإدارته يُشجع على إيجاد وسائل أخرى لربط العمارة الجديدة بالقديمة. وفقا" لذلك، مشروع البحث الحالي يبحث عن نهج بديل لقوانين الحفاظ بغاية تحقيق هدف التوافق المعماري وتحسين القرارات القائمة على القيم. للحصول على نتائج دقيقة ومقنعة، تم إختيار ودرس حالة وهي مدينة في منطقة الخليج العربي: مدينة الكويت. النتيجة الرئيسية للبحث هي تكوين نهج يمكن تطبيقه بطرح أسئلة إستفسارية عن موقع وتصميم وبناء المباني الجديدة. والأسئلة المقترحة في الأطروحة تركز على القيم التراثية وخيارات التصميم للحصول على تغيير مدروس في المناطق المعنية. كما أنها تساعد على تقييم مقترحات المشاريع الجديدة. لإظهار كيف يمكن أن يُقدم ويُستخدم هذا النهج من قبل المصممين والمقيمين، تم تكوين نموذج نظري . و قد نوقش هذا النموذج مع مهنيين محليين ودوليين حيث قاموا بتحديد نقاط قوته وقيوده. وتشيرالنتائج الإجمالية إلى أن توفير القوانين و/أو الأسئلة الإستفسارية ليس حلا" مرضيا" لأنه يوجد مسائل أخرى لابد من معالجتها: كيفية تطبيق التوجيه بشكل فعلي عندما يتم إنشاؤه، وكيفية تطوير مهارة أخذ القرارات القائمة على القيم، وكيفية إدخال المحافظة على التراث بعقلية الحكومة المحلية والمجتمع. عندما تعالج تلك المسائل يمكن للتراث أن يصبح جزءا" من عملية التخطيط. فهذا هو الهدف النهائي. وأخيرا"، يُنصح بأخذ خمس إتجاهات بحثية لمواصلة التحقق من الأفكار التي وردت في هذه الدراسة

Multi functional health monitoring wearable devices are quite prominent these days. Usually these devices are battery-operated and consequently are limited by their battery life (from few hours to a few weeks depending on the application). Of late, it was realized that these devices, which are currently being operated at fixed voltage and frequency, are capable of operating at multiple voltages and frequencies. By switching these voltages and frequencies to lower values based upon power requirements, these devices can achieve tremendous benefits in the form of energy savings. Dynamic Voltage and Frequency Scaling (DVFS) techniques have proven to be handy in this situation for an efficient trade-off between energy and timely behavior. Within imec, wearable devices make use of the indigenously developed MUSEIC v2 (Multi Sensor Integrated circuit version 2.0). This system is optimized for efficient and accurate collection, processing, and transfer of data from multiple (health) sensors. MUSEIC v2 has limited means in controlling the voltage and frequency dynamically. In this thesis we explore how traditional DVFS techniques can be applied to the MUSEIC v2. Experiments were conducted to find out the optimum power modes to efficiently operate and also to scale up-down the supply voltage and frequency. Considering the overhead caused when switching voltage and frequency, transition analysis was also done. Real-time and non real-time benchmarks were implemented based on these techniques and their performance results were obtained and analyzed. In this process, several state of the art scheduling algorithms and scaling techniques were reviewed in identifying a suitable technique. Using our proposed scaling technique implementation, we have achieved 86.95% power reduction in average, in contrast to the conventional way of the MUSEIC v2 chip’s processor operating at a fixed voltage and frequency. Techniques that include light sleep and deep sleep mode were also studied and implemented, which tested the system’s capability in accommodating Dynamic Power Management (DPM) techniques that can achieve greater benefits. A novel approach for implementing the deep sleep mechanism was also proposed and found that it can obtain up to 71.54% power savings, when compared to a traditional way of executing deep sleep mode. / Nuförtiden så har multifunktionella bärbara hälsoenheter fått en betydande roll. Dessa enheter drivs vanligtvis av batterier och är därför begränsade av batteritiden (från ett par timmar till ett par veckor beroende på tillämpningen). På senaste tiden har det framkommit att dessa enheter som används vid en fast spänning och frekvens kan användas vid flera spänningar och frekvenser. Genom att byta till lägre spänning och frekvens på grund av effektbehov så kan enheterna få enorma fördelar när det kommer till energibesparing. Dynamisk skalning av spänning och frekvens-tekniker (såkallad Dynamic Voltage and Frequency Scaling, DVFS) har visat sig vara användbara i detta sammanhang för en effektiv avvägning mellan energi och beteende. Hos Imec så använder sig bärbara enheter av den internt utvecklade MUSEIC v2 (Multi Sensor Integrated circuit version 2.0). Systemet är optimerat för effektiv och korrekt insamling, bearbetning och överföring av data från flera (hälso) sensorer. MUSEIC v2 har begränsad möjlighet att styra spänningen och frekvensen dynamiskt. I detta examensarbete undersöker vi hur traditionella DVFS-tekniker kan appliceras på MUSEIC v2. Experiment utfördes för att ta reda på de optimala effektlägena och för att effektivt kunna styra och även skala upp matningsspänningen och frekvensen. Eftersom att ”overhead” skapades vid växling av spänning och frekvens gjordes också en övergångsanalys. Realtidsoch icke-realtidskalkyler genomfördes baserat på dessa tekniker och resultaten sammanställdes och analyserades. I denna process granskades flera toppmoderna schemaläggningsalgoritmer och skalningstekniker för att hitta en lämplig teknik. Genom att använda vår föreslagna skalningsteknikimplementering har vi uppnått 86,95% effektreduktion i jämförelse med det konventionella sättet att MUSEIC v2-chipets processor arbetar med en fast spänning och frekvens. Tekniker som inkluderar lätt sömn och djupt sömnläge studerades och implementerades, vilket testade systemets förmåga att tillgodose DPM-tekniker (Dynamic Power Management) som kan uppnå ännu större fördelar. En ny metod för att genomföra den djupa sömnmekanismen föreslogs också och enligt erhållna resultat så kan den ge upp till 71,54% lägre energiförbrukning jämfört med det traditionella sättet att implementera djupt sömnläge.
