The major objective of this empirical research is to identify and explain the level of regional development and analyse the challenges of policy implementation with special focus on Tigray and Gambella Regions from 1995 to 2015. In line with the research objectives and statement of the problem, this study was designed to determine the level of development of the two regional states, the critical factors of regional growth in the regions, and what the major challenges were in the implementation of regional development policy. This research was explanatory cross-sectional in its design. In this research, both primary and secondary sources were consulted. Key informant interview, document review and observation were used to collect the necessary information. Accordingly, based on their expertise knowledge, and the position they held, a total of 24 regional and federal key informants were purposively selected and interviewed. The findings of the study showed that both regions made remarkable improvements and changes in health, education, road network, agricultural and revenue collection performance. However, contrary to the perceptions of the respondents, the secondary data when divided by regional population showed that in the past 20 years Gambella has been better off in terms of health, education, road networks and some agricultural indicators than Tigray. Tigray, however, grew more in terms of infrastructure than Gambella during the same period. The study found that the Government regional development policy designed and implemented as measured by growth-oriented indicators brought encouraging results. The most important determinant factors for regional economic development between the two sampled regions were: initial historical level of development; capacity of resource utilisation; leadership commitment, cultural differences, recurrent conflicts and insecurity, governance issues, political will, capacity of the regional government authorities; and rent-seeking attitude of politicians and civil servants. To address some of the challenges, few recommendations are made: designing a regional specific development policy, strengthening intergovernmental relations, protecting the environment, ensuring good governance, maintaining peace and security, strengthening capacity building, supporting infrastructural development for Gambella and the provision of additional financial incentives to regions. / Development Studies / D.

Föräldrainflytande är ett komplext begrepp och en viktig del i förskolans värdegrundsarbete och demokratiuppdrag. Det är föräldrarna som har det yttersta ansvaret för barnet samt känner sitt barn allra bäst. En god samverkan mellan föräldrar och förskolan som möjliggör föräldrainflytande är därför viktigt för att kunna skapa de bästa förutsättningarna för barnet. Syftet med den här studien är därför att undersöka föräldrars upplevelser av föräldrainflytande i förskolans verksamhet med specifikt fokus på vilan. För att få svar på studiens frågeställningar har enkäter samlats in från sex föräldrar med barn i ett till treårsåldern som går i förskolan. Begreppet inflytande problematiseras med hjälp av inflytandetrappan, vilken synliggör olika nivåer av inflytande som alla är viktiga för att kunna tala om ett reellt föräldrainflytande. Vid första anblick tyder resultatet på att föräldrarnas syn på sina möjligheter till inflytande är övervägande goda. Men vid en närmare granskning av föräldrarnas beskrivningar och exempel synliggörs att det finns begränsningar i föräldrainflytandet, vilket leder till att föräldrarna inte får, eller inte utnyttjar sina möjligheter till att utöva ett reellt föräldrainflytande. / Parental influence is a complex concept and an important part of the preschool's value-based work and democracy mission. It is the parents who have the ultimate responsibility for the child and know their child best. A good collaboration between parents and the preschool that enables parental influence is therefore important in order to be able to create the best conditions for the child. The purpose of this study is therefore to investigate parents' experiences of parental influence in the preschool's activities with a specific focus on the childs rest. To get answers to the study's questions, questionnaires were collected from six parents with children aged one to three years who go to preschool. The concept of influence is problematised with the help of the influence ladder, which makes different levels of influence visible, all of which are important in order to be able to talk about a real parental influence. At first glance, the results indicate that the parents' views on their opportunities for influence are predominantly good. However, a closer examination of the parents' descriptions and examples reveals that there are limitations in the parental influence, which leads to the parents not being able to, or not using, their opportunities to exercise a real parental influence.

This thesis is aimed at assessment of drainage conditions at the river Loucna in the cadastral area of Dasice. The examined section is 3,88 km long and runs through out of the city and in the city of Dasice. On the left bank of the river there are several historic buildings that are potentially at risk for 100 years of flow. Capacity assessment is performed using the 1D mathematical program HEC - RAS in which the flow model is created and the calculation of the flow rates for individual N - year flows. On the basis of the results of the program is conducted conceptual desing of flood protection measure. At the same time is conducted conceptual desing of fish ladder on the weir and a sluice closure on the intake for the race.

Le travail présenté dans ce manuscrit porte sur deux sujets distincts. Le premier concerne la réponse d'un diélectrique cristallin à un champ électrique uniforme ; il s'ancre sur la théorie moderne de la polarisation développée par King-Smith, Vanderbilt et Resta. En nous restreignant d'abord au cas unidimensionnel, nous décrivons de manière perturbative à faible champ électrique le spectre de Wannier-Stark d'un modèle de bande. Nous utilisons ensuite ce développement dans une approche thermodynamique que nous modifions pour palier aux problèmes posés par le caractère non-borné du spectre de Wannier-Stark : nous introduisons en particulier un potentiel chimique local assurant la neutralité électrique locale au sein du cristal. Cette approche permet d'accéder à la polarisation et à la susceptibilité électrique des cristaux diélectriques. Finalement, nous étendons le travail effectué au cas bidimensionnel où de nouvelles caractéristiques associé aux isolants topologiques apparaissent.Le deuxième sujet porte sur la synchronisation de spin dans les gaz d'atomes froids. Nous étudions la compétition entre le mécanisme d'écho de spin et le phénomène d'auto-synchronisation lié à l'effet de rotation des spins identiques (emph{ISRE}). La méthode de l'écho de spin permet de compenser certains déphasage apparaissant dans une gaz d'atomes ultra-froid piégé, et accroît ainsi le temps de cohérence de l'ensemble. L'emph{ISRE} apparaît dans les gaz denses via les collisions entre atomes et conduit également à un accroissement du temps de cohérence. Nous montrons que ces deux mécanismes ne sont pas systématiquement compatibles. En particulier, leur compatibilité est lié à la relation entre les échelles de temps propres à chacun des phénomènes. / The work exposed in this manuscript covers two distinct topics. The first is about the response of crystalline dielectrics to an external static electric field; it is based on King-Smith, Vanderbilt and Resta modern theory of polarisation. Restricting ourselves to the 1D case, we first describe the Wannier-Stark ladder of a band model with a low-field perturbative approach. We then use this development to derive the thermodynamical response of the band model. We have to modify the usual thermodynamics to account for the unboundedness of the Wannier-Stark spectrum, through the introduction of a local chemical potentiel which ensures local electric neutrality in the crystal. In a last step, we extend our approch to the 2D cas, where new characteristics related to the topic of topological insulators appear.The second topic tackles synchronization and spin-echo in cold atom gases. We study the competition between the spin-echo mechanism and the self-synchronization mechanism which emerges from the identical spin rotation effet (emph{ISRE}). The spin-echo thechnique was built to compensate for some the of dephasing that appears in trapped ultra-cold gases, leading to an increased coherence time for the ensemble. The emph{ISRE} appears in dense atomic clouds where collisions also lead to an increased coherence time. We show that these two mechanism are not always compatible, in particular, their compatibility is based on the relation between the time scales associated to both phenomena.

Freileitungsmaste aus herkömmlichen Beton werden bereits heute in großer Zahl in Mittelspan-nungsnetzen eingesetzt. Im Bereich der Hochspannungsfreileitungen existieren bisher international nur wenige erste Freileitungen mit Masten aus herkömmlichen Beton. Um zukünftig Elektroenergie über große Entfernungen über Trassen mit geringen Flächenbedarf transportieren zu können, sind neue Hochspannungsfreileitungen in kompakter Bauweise notwendig. Um dieses Ziel zu erfüllen, sollen die Kompaktmaste aus ultra-hochfestem Beton (UHPC) hergestellt werden. Dafür ist eine neue Sorte von UHPC mit hoher Festigkeitsklasse zu entwickeln. Die mechanischen, elektrischen und thermischen Eigenschaften des neuen Betonmaterials waren zunächst unbekannt. Bisher gab es kaum Kenntnisse über die elektrischen und thermischen Belas-tungen, die auf die Betonmaste einer Freileitung in kompakter Bauweise einwirken. Ein Teilthema im interdisziplinären Forschungsprojekt „KoHöMaT“ (gefördert durch das Bundesmi-nisterium für Wirtschaft und Energie) war es, gemeinsam mit Forschungsinstituten (IMB, Fichtner, Lapp, Europoles, KIT, iBMB) die Materialparameter des neuen UHPC zu bestimmen. Den Einfluss der elektromagnetischen Belastungen auf die Lebensdauer und die Festigkeit des Ver-bundes aus Stahl und Beton habe ich untersucht. Aufgabe meiner Arbeit ist es auch, die elektrischen und thermischen Eigenschaften, wie die elektrische Leitfähigkeit, die elektrische Festigkeit, die Per-mittivität, den Verlustfaktor und die Wärmeleitfähigkeit experimentell zu bestimmen. Anhand der experimentellen Untersuchungen wurde der Versagensmechanismus des UHPC-Betons bei Span-nungsbelastung identifiziert. Die am Betonmast auftretenden elektrischen und thermischen Belas-tungen wurden mit Hilfe von verschiedenen FEM-Modellen berechnet und den gemessenen Fes-tigkeiten gegenübergestellt. Es wurde der Einfluss permanenter elektrischer Felder auf die mechanischen Eigenschaften des UHPC bestimmt. Hierfür wurde die Druckfestigkeit des Betons vor und nach Dauerversuchen bei verschiedenen Spannungsbelastung gemessen. Der Verbund zwischen Stahl und Beton wurde in Lastwechselversuchen thermisch hoch beansprucht und dessen mechanische Festigkeit vor und nach der thermischen Belastung bei Auszugsversuchen gemessen. Aufgrund der befürchtenden gesundheitlichen Risiken für Menschen und Tiere, sowie der gegen-seitigen Beeinflussung benachbarter elektronischer Systeme (EMV) dürfen die elektromagnetischen Felder von Freileitungen die jeweiligen maximal zulässigen Grenzwerte nicht überschreiten. Ich habe die Berechnungen der elektrischen und magnetischen Feldverteilung für die im Verbundvorhaben entwickelten Mastdesigns durchgeführt. Gemeinsam mit den Forschungsinstituten (Europoles, Fichtner, Lapp) wurden die Mastdesigns hinsichtlich der Feldverteilung optimiert. / The Overhead line towers made of conventional concrete are already used in large numbers in the medium voltage nowadays. So far, only a few towers of overhead transmission line made of con-ventional concrete which exists internationally in the area of high voltage. In order to be able to transmit electrical energy over long distances by routes of less floor space requirements, new high voltage overhead lines in compact construction are necessary. To achieve this goal, the compact towers have to be made of ultra-high-performance concrete (UHPC). Therefore, a new kind of UHPC with a high strength class has to be developed. For this kind of new concrete, the mechanical, electrical and thermal characteristics were unknown till now either, there was rare knowledge about the electric and thermal loads which have an effect on the concrete towers of an overhead line in compact construction method. The main purpose part of this interdisciplinary research project 'KoHöMaT “, which funded by the Federal Ministry for Economic Affairs and Energy), was to identify the material parameters of the new UHPC together with the following research institutes (IMB, Fichtner, Lapp, Europoles, KIT, iBMB). It was examined the influence of electromagnetic loads on the lifetime and its’ strength bond be-tween both of composite steel and concrete, also as my major involve was to determine the elec-trical and thermal properties experimentally, such as electrical conductivity, electrical strength, per-mittivity, dissipation factor and finally thermal conductivity. As a result, the failure mechanism of the UHPC under the electrical stresses has been identified then,the electrical and thermal loads on the concrete towers were calculated by using various FEM models accordingly, the measured values were used in the determination of electrical strength. All mentioned theoretical calculated parameters were compared with the real measured parameters. The influence of permanent electric fields on mechanical properties of the UHPC was determined as well. Mainly, the compressive strength of the concrete was measured before and after durability tests at different voltage loads. In addition, the composite (interface) between steel and concrete was thermal extremely loaded by alternating load tests. Its mechanical strength has been measured by pull-out tests before and after this thermal loads. Due to the fear of health risks for both humans and animals, as well as the mutual influence of neighboring electronic systems (EMV), the electromagnetic fields of open lines must not exceed the respective maximum permissible limit values. The calculations of the electrical and magnetic field distribution were carried out for the mast design developed in the composite project. Together with the other research institute (Europoles, Fichtner, Lapp). the tower designs were optimized with re-gard to the field distribution.
