Maroha, Emile. « Relativistic and no-relativistic energy levels, oscillator strengths, lifetimes and transition probabilities for S III ». DigitalCommons@Robert W. Woodruff Library, Atlanta University Center, 2014. http://digitalcommons.auctr.edu/dissertations/1593.
Texte intégralRésumé :
Energy levels, oscillator strengths and transition probabilities for dipole-allowed transitions among levels of the terms belonging to the 3s23p2, 3s3p3, 3s23p3d, 3s23p4s, 3s23p4p, 3s23p4d, and 3s23p5s configurations of S in are calculated using the multiconfiguration Hartree-Fock (MCHF) method. The relativistic effects are incorporated through mass, Darwin, spin-orbit, and spin-other-orbit operators in the Breit-Pauli Hamiltonian in our calculations of the energy levels, oscillator strengths, transition probabilities and lifetimes for all fine-structure levels belonging to these configurations. The present results are compared with other available calculations and measurements. These data provide a powerful tool to study the composition, structure, dynamics and energetics of atmospheres of the Io-torus-Jupiter system and other astrophysical objects.

Forsberg, Jonas. « Energy transition in transportation : Applying TIMES-based energy system optimisation models to sub-national levels ». Licentiate thesis, Luleå tekniska universitet, Energivetenskap, 2021. http://urn.kb.se/resolve?urn=urn:nbn:se:ltu:diva-83534.
Texte intégralRésumé :
Transportation is embedded in the fabric of society and a key enabler of socio-economic development, but it is also a major source of carbon dioxide (CO2) and local air pollution (AP). Cities collectively account for around three quarters of total energy-related CO2 emissions, and the negative health impacts from local APs are most felt in dense urban environments. Thus, transitioning away from current fossil fuel regime in urban transportation is necessary to address both global and local challenges. Mathematical models as energy system optimisation models (ESOMs) are commonly applied to explore contrasting energy futures and to provide insights on how the energy system (or specific sub-sectors) may evolve under different conditions. However, ‘typical’ national level models are not fully adapted to capture the characteristics of local (city) transportation, and previous city-level ESOM based analyses have focused on decarbonisation of local energy systems, thus omitting other local policy considerations as e.g. air quality, and several studies excluded transportation altogether. In this thesis, a generic city-level ESOM framework (TIMES-City) was further adapted and used to provide policy-relevant insights on the anticipated energy transition of the local transport sector. The underlying work rests on a systems analysis approach, building on careful consideration of the overall system performance and boundaries, understanding of specific system characteristics, and challenges and opportunities facing local ‘system managers’; this has implications for model representation and for quantitative and qualitative modelling assumptions. Further, availability and quality of local transport, energy and emission data needed to calibrate models poses significant challenges, and considerable effort was also put on producing projections for future transport demand (a key model input), using lessons and input data from traditional transport demand models. These considerations were addressed in Paper I. The model was then applied to two different cases (in Sweden) to explore potential conflicts and co-benefits between ambitious climate targets and deep cuts in APs (Paper II), and to assess the roles of local and regional governments in CO2 mitigation when also considering ambitious national-scale policies (Paper III). The results of Paper II indicate that substituting fossil fuels for biofuels in conventional vehicles is the least-cost decarbonisation pathway, however this produces only minor or even negative benefits to air quality. While, zero-emission vehicles cut all local tail-pipe emissions, but their total impact on climate change mitigation is determined by upstream impacts from the conversion and distribution of energy carriers. Thus, ensuring low levels of total CO2 and APs from transportation calls for re-coupling of the local and global responsibilities and motivations into comprehensive mitigation strategies. The results of Paper III indicate that current Swedish national mitigation measures will drive down CO2 emissions in transportation considerably, but biofuel availability and BEV (battery electric vehicles) costs are critical for the rate and extent of the transition, while locally and regionally determined measures to enable shifts (from car) to active travelling, public transportation and home-based work have a much more limited direct impact. Nonetheless, these measures, along with city investments in BEVs and charging infrastructure which pave the way also for residents and local businesses, can help to reduce overall energy intensity of the transport sector, thus slowing down growth in fuel demand and contribute to reaching ambitious climate targets with limited renewable resources (as e.g. biofuels). The two studies (Papers II and III) illustrate the usefulness of applying comprehensive ESOMs also at sub-national levels, providing insights on both global and local sustainability implications as well as deeper understanding of the roles of local and regional decision-makers in enabling and supporting low-carbon transitions in transportation.

Ebem, Zeynep. « Health Promoting Behaviors And Exercise Stages Of Change Levels Of University Students At Transition To University ». Master's thesis, METU, 2007. http://etd.lib.metu.edu.tr/upload/12608828/index.pdf.
Texte intégralRésumé :
The purposes of this study were to examine (a) health promoting behaviors, (b) physical activity levels, (c) exercise stages of change levels, and (d) exercise preferences of students who had just entered the university by gender and residence. Participants were 438 students from Middle East Technical University (METU) English Preparatory school. Adolescent Health Promotion Scale (AHPS), International Physical Activity Questionnaire (IPAQ), Physical Activity Stages of Change Questionnaire (PASCQ), and Physical Activity Preferences Check-list were used for the data collection. Descriptive statistics, nonparametric statistical methods (Mann Whitney U test, Pearson chi-square test), and a one-way MANOVA were used for the data analysis. According to AHPS results, female students’
health promoting behaviors were better than those of male students except exercise behavior. Students living at home had higher scores on nutrition behavior and students living in dormitory had higher scores on stress management behavior (p <
.05). According to the IPAQ results, male students were more physically active than female counterparts. Students who were living in dormitory had higher physical activity levels than students living at home (p <
.05). PASCQ findings indicated no significant differences on the exercise stages of change levels by gender and residence (p >
.05). In general, students were at pre-contemplation 9.2%, contemplation 39.3%, preparation 27.8%, action 14.5%, and maintenance 9.2% stages. Swimming, walking, and table tennis were the three most frequently preferred physical activities. In conclusion, female students had better health promoting behaviors than those of male students except exercise behavior. Female students and students living at home were more at risk of inactivity. Approximately 80% of the METU English Preparatory school students&

Texte intégralRésumé :
The current study assessed perceived s of knowledge, involvement, and importance of transition planning and service delivery among secondary special education teachers in the Commonwealth of Virginia. Relationships were also explored between these levels and years of experience teaching students with special needs, category of students taught 1 highest degree earned, and contact hours training from in-service, coursework, and conferences in transition.
A survey instrument was mailed to secondary special education teachers in the Commonwealth of Virginia. Ninety-two percent of the 236 survey recipients responded to the survey. Data from the survey included descriptive information regarding: years experience teaching students with disabilities, category taught, highest degree, and contact hours in conferences , courses, and in-services in years 1993-94, 1994-95, 1995-96. Data from the survey also included respondents' levels of knowledge, involvement, and importance of transition planning and service delivery. Survey data were analyzed to reveal differences among descriptive data and levels of knowledge, involvement, and importance.
Significant findings from the study indicate that secondary special education teachers in Virginia perceive their knowledge of transition planning and service delivery in the low to medium range, their involvement in transition in the low to medium range, and the importance of transition planning and service delivery in the medium to high range.
Significant findings from the study also included the positive relationship between knowledge of transition planning and service delivery and courses taken over the three year period of 1993-1996, conference contact hours over the same three year period, and inservice contact hours. Additionally significant was the positive relationship between involvement in transition planning and service delivery and inservice contact hours 1993-1996, conference contact hours over the same three year period, and courses taken. The level of importance of transition planning and service delivery was not affected by training options. Implications for LEAs in Virginia, implications for personnel preparation, and directions for future research are discussed.Ed. D.

Texte intégralRésumé :
In modern society, the role of fathers in parenthood tends to be as considered as the role of mothers. Becoming parent can lead to some positive effects, but also to some negative ones, which may have serious consequences on both parents and on the child. The purpose of the present work was to investigate whether a difference of a specific postpartum effect with regard to levels of perceived stress could be noticed in Swedish and French men who just became fathers for the first time. In this study, we pointed out the stress in daily life and the stress related to the role as a parent. All participants (nSwedish = 20; nFrench = 31) were men who became fathers for the first time a year or less before the measurement of stress. A questionnaire was submitted online and the data were analyzed using t-tests in order to measure the differences between French and Swedish regarding stress and ANCOVAs in order to measure if age and duration of the relationship have an impact on stress level. The results showed that Swedish fathers have a significantly higher perceived stress level than French fathers. However, there is no effect of age and duration of the relationship on the results. Moreover, no differences were found with respect to fathers’ parenting stress level.

Texte intégralRésumé :
This article examines the patterns and prevalence of trauma in 256 Late Lima individuals. is assemblage of human remains comes from the sites of Huaca 20 and Copacabana and was compared to 45 Middle Lima individuals from thesite of Cerro Culebra, as well as 30 individuals from the Middle Horizon 2 and 4 (Miramar). Other investigators have proposed that social and political changes during the transition into the Middle Horizon on the Central Coast of Perumight have caused an increase in episodes of violence in the local population. e results of this investigation, however, show that this transition witnessed a reduction in of non-lethal episodes of violence, especially for women, with occasional episodes of more violent and lethal clashes. is situation seems to have been maintained with the consolidation of Wari imperial presence (or inuence). ese observations for the Central Coast contrast heavily with those made for patterns of violence in the South Coast and Highlands during the same period. It is thus proposed that Wari presence in peripheral zones did not always trigger the same social consequences, possibly as the result of distinct political strategies of expansion utilized by the Wari state.El presente artículo examina las prevalencias y patrones de los traumatismos de probable origen intencional presentes en 256 individuos Lima Tardío (Huaca 20 y Copacabana), comparando los resultados con los de 45 individuos Lima Medio (Cerro Culebra) y 30 individuos del Horizonte Medio 2 a 4 (Miramar), buscando dilucidar si los cambios políticos y sociales experimentados durante la transición al Horizonte Medio pudieron haber ocasionado un alza en los episodios de violencia vividos por las poblaciones locales.Los resultados de esta investigación indican que al parecer la introducción wari en la Costa Central signicó una disminución de los episodios de violencia no letal, especialmente para las mujeres, con ocasionales episodios de enfrentamientos más violentos que conllevaron a la muerte. Esta situación parece haberse mantenido una vez consolidada la presencia (o inuencia) imperial. Asimismo, se observó que los niveles y patrones de violencia durante la transición y consolidación wari en la Costa Central fueron distintos que los experimentados en la costa y sierra sur, deduciéndose a partir de esto que la presencia wari en las zonas periféricas no siempre desencadenó las mismas consecuencias sociales, obedeciendo posiblemente a las distintas estrategias políticas de expansión por parte de dicho estado.

Texte intégralRésumé :
The interaction between light and organometallic chromophores has been investigated theoretically in a strive for fast optical filters. The main emphasis is on two-photon absorption and excited state absorption as illustrated in the Jablonski diagram. We stress the need for relativistic calculations and have developed methods to address this issue. Furthermore, we present how quantum chemical calculations can be combined with Maxwell's equations in order to simulate propagation of laser pulses through a materials doped with chromophores with high two-photon absorption cross sections. Finally, we also discuss how fast agile filters using spin-transition materials can be modeled in order to accomplish theoretical material design.

Texte intégralRésumé :
This thesis examines how policy narratives inform the regional planning approach to sustainable infrastructure transitions. Many infrastructure systems are locked into unsustainable paths, resulting in policy, land use and infrastructure relationships that are path dependent. The research finds policy narratives indicate that infrastructure systems are reconfigured amid tensions, resistance and trade-offs that inhibit and displace sustainable innovation and transition pathways. In its current traditional form, regional planning is bound to highly institutionalised and normative conditions that resist innovative, co-evolutionary and transformative change in pursuing sustainable infrastructure transitions.

Texte intégralRésumé :
Im Lebenslauf ist die Berufswahl eine zentrale Entwicklungsaufgabe. Durch die Institutionalisierung des Lebenslaufes in modernen Gesellschaften wird der Prozess auch institutionell begleitet. Schule organisiert in Kooperation mit der Bundesagentur für Arbeit dazu berufsorientierende Angebote, die u.a. die Entwicklung der Berufswahlreife unterstützen sollen. So werden neben den Eltern auch die Schule und Berufsberatung zu zentralen Vermittlern (Gatekeepern) beim Übergang von der Schule in die Ausbildung. Im Rahmen der Analyse des Berufswahlprozesses ist es wichtig, die Interaktion zwischen „Umwelt und Person“ zu betrachten: Wie gelingt es Jugendlichen, diese Entwicklungsaufgabe anhand personaler und sozialer Ressourcen, sowie im Rahmen gesellschaftlicher Strukturen, zu bewältigen? Diese Fragestellung ist grundsätzlich nicht neu, gewinnt jedoch unter den aktuellen gesellschaftlichen und ökonomischen Übergangsbedingungen eine große Bedeutung.
Schulen haben in den letzten Jahren verstärkt begonnen, ihre Berufsorientierung systematisch zu organisieren und weiterzuentwickeln. Die Fülle der neu entwickelten Konzepte und Programme zur Verbesserung der Berufsorientierung steht jedoch in keinem Verhältnis zum Stand der empirischen Forschung. Daher ist die vorliegende Forschungsarbeit von der zentralen Zielstellung geleitet, die empirische Evidenz zur Wirkung schulischer Berufsorientierungsangebote zu erweitern. Im Mittelpunkt der Studie steht die Fragestellung, wie sich der schulische Berufsorientierungsprozess für Schülerinnen und Schüler aller Bildungsgänge für einen verbesserten Übergang in weiterführende Bildungs- und Ausbildungssysteme optimieren lässt. Von Interesse ist dabei, ob und inwieweit schulische Angebote die Entwicklung der Berufswahlreife der Schülerinnen und Schüler beeinflussen, welche Angebote als besonders unterstützend oder weniger sinnvoll beurteilt werden müssen. Diese Fragestellungen wurden auf Basis von schriftlichen Befragungen im Zeitraum von 2008 bis 2010 von Oberschülerinnen und Oberschülern im Landes Brandenburg bearbeitet. Anhand von Querschnitts- und Panelanalysen werden Aussagen über die Wahrnehmung und den Einfluss der verschiedenen schulischen Angebote sowohl für einzelne Jahrgangsstufen als auch im Vergleich zwischen den Jahrgangsstufen getroffen.The study focussed on the question of how career orientation programs for students in middle schools transitioning into advanced educational and vocational levels could be optimized. Particularly of interest was the degree of influence school programs had on the career choices of students and which programs were supportive and which were deemed as not having value. The answers to these questions should help to critically analyze, further develop and adapt current career orientation programs in schools. The accompanying article should be seen as a guidance for teachers who want to use results in current educational research to further develop the career orientation profiles of their schools. The document is an extract of results from the research „My school, my parents and I in the career orientation process – The career choices of students at the end of middle school between career orientation programs in schools and parental influence“ (SEIB).

Texte intégralRésumé :
The main objective and the major value of this work is to provide a combined setup of theoretical and experimental techniques to simulate and measure a number of properties altered and/or induced by defects in three representative and technologically relevant oxides: zinc oxide (ZnO), zirconium dioxide (ZrO2) and magnesium oxide (MgO).
Zinc oxide and zirconium dioxide are wide-gap semiconductors with a vast set of technological applications generally related to the inclusion of defects and impurities and spanning from optoelectronics to spintronics devices and photocatalysis. They are the subjects of Part II and Part III, respectively. A detailed description of their structure and chemical-physical properties is provided in the respective background sections.
Part II deals with the main subject of this work: bulk and surface zinc oxide properties.
After synthesis, ZnO commonly presents n-type conductivity and in Chapter 3 some of the most common donor defects (specifically: hydrogen interstitial and substitutional to oxygen, zinc interstitial and oxygen vacancy) have been investigated in terms of thermodynamic and optical transition energy levels. The good agreement with existing experimental data provides a powerful validation of the computational method presented in Sec. 2.1.5.1.
In Chapter 4 copper doping of ZnO has been analyzed under different perspectives, spanning from the presence of donor and acceptor states, to magnetic interactions, to cluster tendency and to the interaction with oxygen vacancies. In particular, in conjunction with HREELS experiments, for the first time the inclusion of copper donor impurities in bulk ZnO has been observed which, on the basis of our calculations, we have assigned to interstitial copper species.
In Chapter 5, the most promising shallow acceptor candidate for p-type doping of ZnO, i.e. nitrogen substitutional to oxygen, is investigated. First, nitrogen has been observed in polycrystalline sample and characterized in terms of hyperfine and quadrupolar coupling constants through a combined EPR and theoretical study. Secondly, the nitrogen doping process has been analysed upon the sputtering with ammonia of the mixed-terminated ZnO (10 0) surface through TDS experiments. The effectiveness of the doping process and the fundamental role of post-treatment oxidation were proved. The defective states within the optical gap have been estimated using HREELS measurements with a 66 eV electron primary energy. The computation of the transition energy levels have then demonstrated that nitrogen acts as a deep acceptor species in ZnO, disappointing the hopes to achieve p-type conductivity through nitrogen-doping.
In order to get more insight in the nitrogen doping mechanism, the reactivity of ZnO single crystal and powders towards ammonia has been addressed by a combined theoretical and HREEL and UHV-FTIR study, in Chapter 6. Different coverages have been considered and, while at low concentration only molecularly adsorbed species have been observed, at a full monolayer coverage the repulsive steric interactions between adsorbates have been shown to induce the formation of an ordered adlayer with (2 x 1) periodicity, presenting alternating molecular NH3 and singly deprotonated NH2 moieties adsorbed on cationic sites.
Part III is focused on ZrO2, specifically the tetragonal polymorph which is commonly stabilized by impurities. In particular, here the interest is related to the titanium doping of the material, which was experimentally found to induce a large red shift of the optical absorption edge. In Chapter 7 we proposed a rationalization of this experimental observation based on the computation of the optical transition levels of Ti species. The possible interaction with oxygen vacancies has also been considered.
In Part IV the nitrogen doping of MgO, recently proposed as potential route to achieve room temperature ferromagnetism has been investigated. This work was divided in two parts.
In Chapter 8 the electronic structure and the spin properties of nitrogen impurities have been theoretically studied, considering also possible charge transfers with magnesium or oxygen vacancies.
Finally, in Chapter 9 we show how a trapped N2‒ radical anion in the polycrystalline material has been identified and characterized through a combined EPR and DFT study.

Texte intégralRésumé :
This thesis develops the notion of the bioenergy transition as the long-term transformation of biomass from a local resource into a global commodity. An historical assessment is combined with interdisciplinary analysis that focuses especially on liquid biofuels and highlights the environmentally innovative case of bioethanol. The bioenergy transition is investigated from several different perspectives: technical-economic, socio-economic, socio-technical and political-economic. Linkages across different levels from household to global are analysed in relation to the effectiveness of bioenergy policies. In addition to studies at household and national levels, a North-South perspective is taken by including two major regions: the European Union (EU) and the Southern African Development Community (SADC). The relation of EU biofuels policy to international climate and trade regimes is assessed to show how regional-global linkages affect policy design and implementation. Household bioenergy markets in developing countries are poorly articulated and difficult to link to other sectors; a detailed choice model in Ethiopia showed that product-specific factors should be evaluated to inform design of programmes and policies. Municipal and sub-national markets for bioenergy have been successfully linked to national policies to coordinate supply and demand in Brazil and Sweden. Regional market development for biofuels has great potential in southern Africa but regional-national linkages currently remain unexploited. National level efforts remain quite important in terms of energy security and environmental innovation, as evidenced in Brazil, Malawi and Sweden. Biofuels sustainability criteria in the EU Renewable Energy Directive (EU-RED) were evaluated in relation to the international climate and trade regimes and were found to shift some costs onto developing countries. One of the mechanisms for assuring biofuels sustainability is bilateral agreements, which remain untested but potentially effective. Cross-level linkages were often unexploited in the cases studied; national approaches cannot easily capture complementarities across sectors and scales in biophysical and economic terms. Linking biofuels markets across different levels from household to global through regional development policies and specialised governance mechanisms could help to steer the bioenergy transition towards sustainability.QC 20141112

Texte intégralRésumé :
Background Fertility transition has yet to accumulate a large set of studies withindividual level data to allow to make wide generalizations. Recently theavailability of data has become better. The current thesis is one step in thedirection of looking into the fertility transition as a whole with individuallevel data and by using event-history methods on the case of Estonia. Objective The study takes the cohort perspective to find out which birth cohorts at whichparities started the fertility transition, what were the different paths takenby urban and rural populations and how did birth spacing change over time. Methods We use register data collected by the First Estonian Republic, which has thefertility histories of birth cohorts of Estonian women born between 1845 and 1919,and fertility processes lasting until the year 1949. We analyse these withpiece-wise constant survival models separately for each parity; having birth cohort,urban-rural residency and piece-wise constant durations since previous birth asthe main variables. Results We find that that probability to next birth starts to decline earlier for thehigher parities and moves to lower parities for later cohorts. For parities 3-7women born in 1873-1880 are first with significantly lower hazard to next birth.For parity 2 the 1880-1887 birth cohort starts the transition. All paritiescontribute to the fertility decline. For the urban population the fertilitydecline is greater in proportion and also lasts less in birth cohorts, while forthe rural population the decline is more gradual and lasts longer. In the birthspacing dimension we find that the average interval between births becameshorter over time across all parities, and for both the urban and the ruralpopulation.

Day, J. « Critical transition phases within top-level female football players in Europe ». Thesis, Liverpool John Moores University, 2018. http://researchonline.ljmu.ac.uk/9478/.
Texte intégralRésumé :
Women’s football has gained in popularity over the last fifteen years and research into this area has developed. (Lopez, 1997; Scraton, Fasting, Pfister, & Bunuel, 1999; Williams, 2003, 2007, 2011; Fasting, 2004; Brus and Trangbaek, 2004; Pfister, 2006; Cauldwell, 2011). This research study has addressed the historical developments and inequalities with women’s football and extended the existing knowledge of women’s football and developed further the understanding of how female players transition through their playing careers. Study One utilized in-depth interviews, (n=6), with senior administrators in the football organization to examine the organizational structure of six football associations (Denmark, England, Finland, Germany, Norway, The Netherlands), in Europe, to understand where women’s football is situated within the organization. The status and location of women’s football in the football organization was scrutinized to identify whether this affects the allocation of resources and working practices within women’s football. The results identified the challenges women’s football faced in gaining adequate resource to develop the women’s game. Gaps in the development structures were identified and this led to the development of Study Two which recognized the need to examine how the players navigate through these structures. Transition models (Wylleman and Lavallee 2014 holistic career model) have framed Study Two to explain how the players transition through their football careers. Seventeen elite players from the six European countries involved in Study One, were interviewed to gain an in-depth insight into how they navigate through their playing career. The findings from Study Two identified that the players found the transition from junior elite football to senior elite football problematic. This depended upon whether they had sufficient junior pathways in place to aid in this transition. Key themes identified in Study One were interwoven into this study, historical social cultural acceptance, migration and dual careers reaffirmed the complex nature of elite women’s football and challenged the transition literature and models to explain how women’s football fits into these models. Despite these complexities the players navigate through their careers, however there is little known about the player to why they continue playing football with all the challenges they face. Study Three aimed to redress this, a case study narrative approach (Douglass and Carless 2006), has been adopted during this study to elicit the players own life experiences and to identify and evaluate the decision-making processes they go through, to play at the elite level. Two players from Study Two were interviewed five years on from their original interviews to explore how they have continued to navigate through the complex journey of women’s football. The stories gave a more in depth insight into the player’s careers and about the player. Resilience and player identity emerged to why these players continue to play at the elite level. The themes of migration and having to combine an academic/ vocation and elite sporting career successfully continued to develop from Study One and Two.

Texte intégralRésumé :
The purpose of this study was to empirically investigate the transition from middle level education to high school, focusing on the 8th to 9th grade transition into a four-year high school. The experimental hypotheses were designed to answer the following questions: (1) What are the transitional effects on the early adolescent self-image? (2) What is the impact of age upon transition? (3) What information can be gained relative to intensity and duration of transition effects? (4) How can the information gained be used to ease the transition from middle level education to a four-year high school? The research design included the spring population of students from two 6-8 grade configuration middle level schools (School 1 and School 2) who will attend a 9-12 senior high school in the fall. A questionnaire composed of seven self-image measures was administered two weeks prior to the end of the 1984/85 school year, three days into the 1985/86 school year, and three days prior to the end of the first quarter of the 1985/86 school year. The findings of this study indicate that the null hypotheses are not supported in their entirety by each of the seven dimensions of self-image. Transition effects, as reported by Occasion 1 and Occasion 2 data, yielded an unexpected decrease in perceptions of victimization, and an expected increase in feelings of anonymity. School 1 revealed no visible effects to self-esteem by the transition, with School 2 reporting an increase in self-esteem 3 days into the transition. For impact of age upon transition, this age group of early adolescents (13 or 14 years old) did not report a decrease in self-esteem or an overwhelming feeling of victimization. Transition effects for the 13 or 14 year old were minimal. Analysis of data from the third administration of the POS would indicate the self-esteem of the population was not negatively effected by the transition. Based on this study, there were decreased perceptions of victimization, and increased perceptions of anonymity by 13 or 14 year olds in transition from the 8th to 9th grade.

Texte intégralRésumé :
Food insecurity affects as significant proportion of the world's population and hence it typically receives priority attention in global policies associated with poverty, equity and sustainable development. For example, it is the first of the Millennium Development Goals and the second of their successor, the Sustainable Development Goals. Access to sufficient and nutritious food is deemed a basic human right. The latest FAO analysis of the “State of Food Insecurity in the World 2014” reports that 805 million people (approximately 11-12% of the world's population) are chronically undernourished (i.e. do not have sufficient energy intake over a period of at least one year). In sub-Saharan Africa the prevalence remains stubbornly high at 24%, the highest in the world. Whilst most interpret food insecurity to mean an insufficient quantity of food (as measured by the number of calories consumed), the widely accepted FAO definition considers four dimensions of food security, namely quantity, quality or diversity, access and use. Provision of enough calories on a daily basis is not sufficient if the diet lacks diversity and appropriate balance to provide the full range of minerals and vitamins necessary for proper health, or if the food available is culturally unacceptable. Thus, there is a pressing need for more nuanced analyses of food security against all four of the dimensions embedded in the concept. Additionally, it is important that these be measured at more local or regional levels because national statistics can mask alarming regional discrepancies in food security, or amongst particular sectors of society, such as recent migrants, refugees, female- or child-headed households, those vulnerable to HIV/AIDS or the landless, to mention just a few. For example, at a national level South Africa is considered a food secure nation with respect to staple requirements, and access to sufficient food is enshrined in the Constitution (Section 27, subsection 1b), but nationally one in twenty (i.e. approx. 2.5 million people) go to bed hungry most nights, and 23% of children below the age of 15 are physically stunted, severely stunted or wasted, due to the long-term ill effects of insufficient food or of inadequate diversity and quality. At a subnational level, there are marked differences between rural and urban populations and even between geographic areas (for example, the prevalence of stunting amongst boys less than 15 years old is 23% in the Eastern Cape, compared to 12% in Gauteng). Once again, despite being a food secure nation, nationally 40% of the population have a dietary diversity score of four or less, which is a cut-off point signifying poor dietary diversity which makes people more vulnerable to malnutrition and ill health, and in Limpopo and Northwest provinces it is as high as 66% and 61%, respectively.

The energy levels, lifetimes, oscillator strengths, and transition probabilities of N II lines have been reported in this thesis. We have used the Hartree-Fock (HF) and Multiconfiguration Hartree-Fock (MCHF) methods in our calculations. The relativistic operators mass correction, one-body Darwin term, spin-orbit interaction, and spin-other-orbit have been included in the Breit-Pauli Hamiltonian in our calculations of atomic parameters of singly-ionized nitrogen. We considered 70 levels of the 2s2 2p2, 2s2 2p3, 2s2 2p 3p, 2s2 2p 3s, 2s2 2p 4p, 2s2 2p 3d, 2s2 2p 4s, and 2s2 2p 4d configurations of N II. Our results have been compared with other available calculations and measurements, and generally a good agreement is found.

Texte intégralRésumé :
This thesis seeks to provide a detailed understanding of the introduction of dockless bike-sharing to London. As part of a wave of new smart and shared mobility services that are aiming to transform the way people move around cities, this emerging form of transport has created disruptions in London since its launch in 2017. This study aims to analyse to what extent dockless bike-sharing aligns or conflicts with the aims and objectives of local authorities governing public space in London. In doing so, it also aims to reveal insights into transformations in contemporary mobility by exploring the dynamics of niche innovations within socio-technical transitions, thus contributing to knowledge in the field of transition studies.To do this, a qualitative case study methodology was employed using document analysis and interviews with four stakeholders integrally involved in the case study, representing both public authorities and a private sector dockless bike-sharing operator, Mobike.The findings demonstrate that dockless bike-sharing is well aligned with the city’s explicit objectives to reduce car dependency and encourage active travel. It has particular potential to make cycling more accessible by bringing bike-sharing to parts of the city that do not have access to the pre-existing, docked bike-sharing scheme, operated by the central transport authority, Transport for London. Despite this, dockless bike-sharing, as a niche innovation, has struggled to break into the existing urban mobility regime. This can be seen to result from a variety of factors that include a failure to collaborate and build local legitimacy or pay sufficient regard to local conditions during early implementation. Furthermore, dockless bike-sharing’s demand for flexible parking has resulted in uses and misuses of public space that have created friction and placed the innovation in conflict with the existing physical urban landscape and the authorities that govern it. Its momentum has been further hindered by London’s complex governance structure, a structure which has not proved conducive to the dockless bike-sharing operating model. It is posited that if dockless bike-sharing is to build momentum and achieve its potential to expand the reach of bike-sharing in London, greater support is required from public authorities.

Morgan, Nathaniel Ray. « A New Liquid-Vapor Phase Transition Technique for the Level Set Method ». Diss., Georgia Institute of Technology, 2005. http://hdl.handle.net/1853/6895.
Texte intégralRésumé :
The level set method offers a simple and robust approach to modeling liquid-vapor interfaces that arise in boiling and condensing flows. The current liquid-vapor phase-transition techniques used with the level set method are not able to account for different thermal conductivities and specific heats in each respective phase, nor are they able to accurately account for latent heat absorption and release. This paper presents a new level set based technique for liquid-vapor phase-transition that accounts for different material properties in each respective phase, such as thermal conductivity and specific heat, while maintaining the interface at the saturation temperature. The phase-transition technique is built on the ghost fluid framework coupled with the standard level set method. A new technique is presented for constructing ghost nodes that implicitly captures the immersed boundary conditions and is second order accurate. The method is tested against analytical solutions, and it is used to model film boiling. The new phase-transition technique will greatly assist efforts to accurately capture the physics of boiling and condensing flows.
In addition to presenting a new phase transition technique, a coupled level set volume of fluid advection scheme is developed for phase transition flows. The new scheme resolves the mass loss problem associated with the level set method, and the method provides an easy way to accurately calculate the curvature of an interface, which can be difficult with the volume of fluid method. A film boiling simulation is performed to illustrate the superior performance of the coupled level set volume of fluid approach over the level set method and the volume of fluid method.

Texte intégralRésumé :
Healthcare delivery within the military requires a multifaceted approach to achieve the desired outcomes of safe, effective, patient-centered, timely, efficient, and equitable health care. The prospect of maintaining a cycle of continuous process improvements within military clinical settings hinge on frontline leaders and middle-level managers who must be prepared to execute the mission and motivate, supervise, coach and mentor the staff. This project showcases a review of current literature translated into the development of an evidence-based Transformational Leadership Induction Program (TLIP) module that consisted of 4 subsections: the environment of care, clinical decision support systems, human resources management, and change management as well as resources for successful leadership within the organization. The training is designed to bridge the transition gap, facilitate role orientation and induction, and socialize frontline and middle-level managers during their role transition. The results of a need assessment survey, approved by the organization, were completed by 30 incumbents and resulted in 57% (17) providing feedback and role-specific contents that were integrated into the development of the TLIP module. The overall response to the survey was positive with 82% (14) of the respondents either agreeing or strongly agreeing with the items that they reviewed. The TLIP module provides a medium that translates current evidence into a succinct training platform capable of enhancing leadership transition and handoff. The TLIP module enables a culture of trust, enhances staff satisfaction, and fosters change management and succession planning within the military healthcare system.

Texte intégralRésumé :
As an expression of current challenges faced by contemporary societies, past decades have witnessed heavy demands for higher education to change and transform. One key question here has been the increased digitalization of higher education. Within this wider setting, this thesis deals with an attempt to handle the increasing shortage of physicians in Sweden by way of digitalizing medical education. The aim of this explorative and longitudinal thesis is to describe and analyze structural and educational transformation work in medical education during the digitalization of the program and the transition from face-to-face to distance education. This thesis focuses on teachers, students and management, who are all heavily involved in this transition of the medical program. Two questions guide the research: (1) what are teachers’ and students’ expectations pending the transition, and what are the influences of already established tools and activities on the program and (2) in what ways do conflicts and changes occur over time, and how do teachers, students, and management deal with these as part of the transition? Cultural-historical activity theory (CHAT) serves as the theoretical framework of the thesis. In particular, the concepts of dominant and non-dominant activities, conflicts, transitional actions, and levels of learning inform the analysis. The data are generated by surveys (N = 108), logging of actors’ activity patterns (N = 100 teachers and 100 students), field studies (65 hours), and interviews (N = 62). The data cover teachers’, students’ and management’s roles in the transition. The analysis shows that the way of theoretically understanding the transition – from a dominant face-to-face activity to a new and unproven non-dominant distance activity – have proved to contribute to deeper understanding of the process of digitalizing medical education. The analysis further displays how the transition from face-to-face to distance education creates considerable conflicts that over time force teachers, students and management into structural and educational transformation work. This type of work successively renders new educational design solutions and new flexible ways of organizing distance medical education. This thesis discusses how the structural and educational transformation work forces actors to collectively engage in the transition by experimenting with new suitable methods and designs, as digital technologies and technology-enhanced learning (TEL) could make sense to teachers and students when they are at a distance.

Texte intégralRésumé :
La lumière est indispensable à la survie des plantes via le processus photosynthétique, pourtant les plantes doivent s'adapter à différentes conditions environnementales où la quantité et la qualité de la lumière peuvent être non optimales pour la photosynthèse. Cela peut provoquer des dégâts photo-induits par formation d'espèces réactives de l'oxygène (ROS), qui sont dangereux pour la plante. Pour limiter la formation des ROS, les plantes mettent en place une régulation importante qui est la dissipation thermique de l'énergie absorbée en excès, appelé Non photochemical quenching (NPQ). Il est connu que la protéine PsbS joue le rôle clé de senseur du pH bas du lumen thylacoïdal, qui est le signal initial pour activer le NPQ. Dans le contexte de cette thèse, on propose d'étudier l'hypothèse que l'absence de la protéine PsbS (diminué NPQ) pourrait augmenter la croissance et la productivité des plantes en conditions contrôlées de faible lumière par l'éminilation de la protéine PsbS chez Arabidopsis thaliana et chez la tomate. Les résultats obtenus indiquent qu'en lumière faible les plantes mutantes montrent une augmentation du rendement de photosystème II conduisant une croissance et un nombre de fleurs significativement augmentés par rapport aux plantes sauvages.De plus, une autre régulation de la photosynthèse, nommée « transitions d'état », est importante pour optimiser la photosynthèse en réponse aux variations de la quantité et de la qualité de la lumière, grâce à la migration réversible des antennes collectrices d'énergie LHCII phosphorylées du PSII au PSI, c'est aussi étudié dans ma thèseLight is indispensable for plant survival, but plants have to cope with different environmental situations where light quantity and quality can be not optimal for photosynthesis. This can cause photodamage due to the formation of harmful reactive oxygen species (ROS). To limit ROS formation, plants developed a mechanism important as the dissipation of excess absorbed energy as heat and is called Non Photochemical Quenching (NPQ). The PsbS protein plays the key role of sensor of the low lumenal pH, the signal to activate NPQ. In this thesis, we proposed and investigated the hypothesis that PsbS absence (NPQ decrease) would improve growth under controlled low light upon elimination of the PsbS in Arabidopsis and tomato plants. Results showed that the increase of photosystem II yield in mutant plants leaded to a significant improvement of growth and flower number in mutants as compared with wild type plants under low light, suggesting that this mutation could be useful to improve plant performances in controlled conditions where light is strongly limiting. In addition, another photosynthetic regulation, called “state transitions”, which is important to optimize photosynthesis under variable light for intensity and quality thank to reversible migration of phosphorylated light harvesting complexes LHCII from PSII to PSI also investigated in my thesis

Green, Andrew. « Transition and acculturation : changing expectations in the move between A level and University ». Thesis, Brunel University, 2006. http://bura.brunel.ac.uk/handle/2438/5480.
Texte intégralRésumé :
This study concentrates upon students making the transition from sixth form to university English Studies. In recent years, this is an issue that has come under increasing scrutiny within the higher education sector and to a lesser degree within the sixth form sector. It is apparent from a growing body of literature that lecturers in higher education are unsatisfied with the relationship between A level and degree level manifestations of subject and with the ability of in-coming undergraduate students to bridge the gap between the two. It is equally clear from the literature that for many students, the experience of moving from A level to undergraduate study is a problematic and often painful process. This thesis considers matters of academic transition and pedagogic encounter within English Studies from the perspectives of both students and teachers. In exploring these issues, a central focus is teachers' and students' expectations and how these are established within the variously constructed learning fora of the sixth form and of higher education. The interaction of these contrasting and sometimes conflicting expectational schemas at the academic borderlands of transition is explored through a detailed consideration of pedagogy and views of pedagogy amongst both teachers and students. The difficulties attendant on creating mutually conducive learning environments, operating to the satisfaction of students and teachers alike, are considered in the light of philosophical frameworks developed out of the writings of Pierre Bourdieu and Lev Vygotsky. The thesis also considers recent and current political developments. The direction of policy-making under New Labour, addressing both 14-19 school education (DfES, 2005) and higher education (DfES, 2003a; DfES, 2003b) witnesses significant changes in the shape and purposes of post-compulsory and higher education. It also signals the advent of further changes, and as such highlights the need for a fuller consideration of the interaction between sixth form and higher education. The widening participation agenda in particular resonates with this thesis' focus on transition, being a factor that may serve further to complexify and problematise the already strained relationship between A level and higher education. By means of surveys of sixth form students, sixth form teachers, first year undergraduates and university lecturers, this thesis draws out the experiences and expectations of teachers and learners on both sides of the A level/university divide. Data arising from these surveys provides a background for more localised data collection conducted through observation and interviews undertaken over the course of one academic year within a large pre-1992 university English department.

Texte intégralRésumé :
This thesis provides a critical review of the Transition movement, a grassroots response to peak oil and climate change, co-founded by this author. It focuses on two key aspects of the Transition approach, resilience and economic relocalisation, with the aim of analysing whether and how they can be implemented in a locality based on the Transition approach, and assessing what socio-economic and community-related structures would be necessary to implement such a process. The focus of the research is Totnes, Devon, which because of its status as the UK’s first Transition initiative and the longer history of various initiatives to promote local resilience, offers a valuable case study of attempts to practically implement resilience and localisation. A variety of research methods were employed, including surveys, focus groups, oral history and in-depth interviews, as well less conventional public participation methods such as Open Space and World Café. The first major finding was that Transition Town Totnes (TTT) has become a significant organisation in the town, with a high level of popular support. It was also found that the obstacles to resilience and relocalisation lie not, as was hypothesised, in a lack of skills or an absence of community cohesion, but in issues of governance and the need for increased social entrepreneurship. It was found that what researchers call the ‘Value Action Gap’ (i.e. the gap between people’s declared sympathies and intentions and their actions) exists in Totnes as much as anywhere else, but that some of TTT’s projects, such as ‘Transition Together’, are working imaginatively to overcome this and to reduce emissions. From this evidence is it concluded that Transition’s approach towards relocalisation and reducing carbon emissions can be argued to be effective in, generating engagement and initiating new enterprises. Like other ‘green’ initiatives, it struggles to engage those from more disadvantaged backgrounds, but some of its initiatives are showing promise for overcoming this. Its primary contribution is in suggesting a redefining of resilience, not as a state of preparedness for disaster, but as a desired characteristic of a sustainable society. A more resilient community, it is argued, would be one more in control of its food and energy production, as well as being one that enables inward financial investment. It also argues that the government focus on ‘localism’, the devolving of political power to the local level, ought to be expanded to include ‘localisation’, the strengthening of local production to meet local needs, a shift which would financially benefit local communities. It argues that the key challenge for Transition initiatives such as TTT is going to be scaling up from being ‘niche’ organisations to become economically viable organisations with a broad appeal and engagement, and also articulates the need for ‘Resilience Indicators’ which would allow communities to measure the degree to which their levels of resilience are increasing.

Texte intégralRésumé :
Es ist eine weit verbreitete Wahrnehmung, dass der Übergang zwischen der Mathematik der gymnasialen Oberstufe und der Mathematik an der Universität für Studierende problematisch sein kann. Besondere Verständnisschwierigkeiten in Bereich der lineare Algebra (lA) bereiten den Studierenden die verschiedenen Herangehensweisen auf diesen beiden Ebenen. Dies lässt sich auf die strukturell-axiomatischer Herangehensweisen an die lA an der Universität, im Gegensatz zu ihrer arithmetisch-geometrischen Darstellung in der Schule, zurückführen. Dies bedingt ebenfalls Unterschiede im prozeduralen und konzeptuellen Verständnis. Ziel dieser Arbeit ist es, zu untersuchen, wie Schüler konzeptuelles Verständnis, Bezug nehmend auf die Theorien von concept definition/image in Verbindung mit multiplen Modi der Beschreibung und des Denkens von Konzepten wie Bilinearität z.B. Skalarprodukt und Multilinearität z.B. Determinanten gewinnen können. Um dies zu erreichen wurde eine substanzielle Lehr-Lernumgebung unter Verwendung einer dynamischen Geometriesoftware (DGS) entwickelt. Die Lerneinheit wurde an einem Berliner Gymnasium eingesetzt und dabei ein vollständiger design-based research Zyklus durchlaufen und eine multiple-level Datenanalyse durchgeführt. Die Ergebnisse der Untersuchung zeigen nicht nur, dass eine Erweiterung der Vorstellungen der Schüler, eine Entwicklung multipler Denkmodi und ein Gewinn tieferen konzeptuellen Verständnisses in der lA erfolgreich vermittelt werden können, sondern geben auch Einblicke in ein mögliches theoretisches Modell, mit dessen Hilfe sich diese Prozesse weiter untersuchen lassen. Weiterhin werden die interaktiven Lehr-Lernmaterialien für die weitere Verwendung im Rahmen von Lehre und Forschung zur Verfügung gestellt. Es öffnen sich neue Forschungsfragen hinsichtlich lokalen Axiomatisierens in der lA der gymnasialen Oberstufe, welches auf einer Integration geometrischer, algebraischer und axiomatischer Denkmodi, unterstützt durch DGS, basieren könnte.A common perception among researchers in mathematics education is that the transition between secondary- and tertiary level of mathematics may be problematic for the students. In particular, the exact and abstract nature of the theory of Linear algebra versus its arithmetic-geometric presentation in school appears to be difficult for the novice students. The application of properties for defining concepts at university in contrast to their usage for describing concepts in school points out a possible occurrence of obstacles for learning and discrepancies in procedural and conceptual understanding. The aim of this study is to examine how could upper-high school students develop a conceptual understanding based on concept definition and concept image in connection to multiple modes of description and thinking about concepts such as bi-linearity exemplified by the dot product of vectors and multi-linearity exemplified by determinants. In order to achieve this, I have created a specific teaching/ learning sequence in a dynamic geometry environment (DGE), then implemented it and evaluated it in a high school in Berlin, following a complete cycle of design-based research and conducting a multiple-level data analysis. The findings of the study show not only that widening students' concept images, developing multiple modes of thinking and gaining deeper conceptual understanding can successfully be mediated by dynamic geometries, but also give insights into an eventual theoretical model of how can they be further examined. Moreover, the study promotes authorized open-source interactive teaching/ learning materials for further sustainable practice and research. It opens new research questions about revisiting axiomatic approaches on local levels in upper high-school Linear algebra which may base on the integration of all three modes of description and thinking geometric, algebraic and abstract possibly facilitated by DGE.
Честа перцепција кај многумина истражувачи во областа на математичкото образование е дека транзицијата помеѓу средното и високото образование по математика може да биде проблематична за студентите. Егзакноста и апстрактноста на теоријата по Линеарна алгебра наспроти нејзината аритметичко-геометриска презентација во средното гимназиско образование се покажува како особено тешка за студентите. Примена на својствата на математичките поими за нивно дефинирање на универзитетско ниво наспроти нивното употреба за опишување на претходно дефинирани поими на училишно ниво, укажува на можна појава на тешкотии при нивното изучување и несовпаѓање на процедуралното и концептуалното разбирање на истите. Целта на оваа студија е да истражи како средношколците би можеле да развијат концептуално разбирање на поимите врз основа на концепт дефиниција и концепт слика во врска со мулти-моди на мислење, конкретно за поими како билинеарност, пр. скаларен производ на вектори, и мултилинеарност, пр. детерминанти. За да ја постигнам оваа цел, креирав наставна содржина поддржана од еден динамичен геометриски систем (ДГС) и следејќи целосен циклус на т.н. design-based research и спрoведувајќи мулти-анализа на податоци, истата ја имплементирав и евалуирав во едно средно училиште во Берлин. Резултатите од студијата укажуваат не само на фактот дека проширувањето на концепт сликите на учениците, развојот на мулти-моди на мислење и стекнувањето на длабоко концептуално разбирање на поимите можат да бидат успешно посредувани од ДГС туку овозможија и увид во еден теоретски модел за тоа коко тие можат понатаму да се истражуваат. Уште повеќе, студијата промовира авторизирани open-source интерактивни материјали за предавање и учење на содржините кои може да служат за понатамошни одржливи истражувања и развој. Студијата отвора нови истражувачки прашања за средношколската Линеарна алгебра која може да се базира на интеграција на сите три моди на мислење, геометриски, алгебарски и апстрактен, поддржан од ДГС.

Texte intégralRésumé :
This exploratory, qualitative study focuses on the transition from junior-to-senior sports. The purpose of the study was to outline the temporal structure of this transition. The aim was to do this by achieving the following three objectives: (1) to develop a working model showing transitional phases in the transition from junior-to-senior sports, (2) to examine demands, resources, barriers, coping strategies, and outcomes within each of the four transitional phases in the working model, (3) to validate the working model through external validation, i.e. through asking the study’s participants for their opinion on the model. There were 10 male participants in this study consisting of active ice hockey players, ice hockey coaches, and a former ice hockey player; preparation phase (n=1), orientation phase (n=1), stabilization phase (n=5), junior coach (n=1), senior coach (n=1), dropout (n=1). Seven instruments were used in this study, including six interview guides and one working model. Initially a working model, depicting four transitional phases, was developed, based on theoretical frameworks and personal experience. A total of 949 raw data units were extracted from the interviews, categorized as either demands, resources, barriers, coping strategies, or outcomes within a transitional phase, and then arranged into category profiles representing each transitional phase in the working model. Furthermore, an empirical model was developed based on the working model and the category profiles. The results are, among other things, discussed in relation to theoretical frameworks and previous research.Denna undersökande, kvalitativa studie fokuserar på övergången från junior-till-senioridrott. Syftet med studien var att kartlägga denna övergångs tidsmässiga struktur. Målet var att göra detta genom att uppfylla följande tre delmål: (1) att utveckla en arbetsmodell som visar transaktionella faser i övergången från junior-till-senior idrott, (2) att undersöka krav, resurser, barriärer, coping strategier och utfall inom var och en av de fyra transaktionella faserna i arbetsmodellen, (3) att validera arbetsmodellen genom extern validering, d.v.s. genom att fråga studiens deltagare om deras åsikter kring modellen. Det var 10 manliga deltagare i denna studie bestående av aktiva hockeyspelare, hockeytränare och en föredetta hockeyspelare; förberedelsefasen (n=1), orienteringsfasen (n=1), stabiliseringsfasen (n=5), junior tränare (n=1), senior tränare (n=1), dropout (n=1). Sju instrument användes i studien; sex intervjuguider och en arbetsmodell. Inledningsvis utvecklades en arbetsmodell, föreställande fyra transaktionella faser, baserad på teoretiska ramverk och personlig erfarenhet. Totalt extraherades 949 rådata från intervjuerna, som sedan kategoriserades som antingen krav, resurser, barriärer, coping strategier eller utfall inom en transaktionell fas, och därefter ordnades de i kategoriprofiler som representerar varje transaktionella fas i arbetsmodellen. Vidare utvecklades en empirisk modell baserad på arbetsmodellen och kategoriprofilerna. Resultatet diskuteras bl.a. i relation till teoretiska ramverk och tidigare forskning.

Texte intégralRésumé :
In this dissertation, I present the results of my research regarding hybrid semiconductor interfaces between organic and inorganic semiconductors. Using photoemission spectroscopy, I elucidate the important role of defect-induced electronic states within the inorganic semiconductor phase. These states significantly affect both the energy level alignment and the charge carrier dynamics at the hybrid interface. I demonstrate that the behavior of these hybrid semiconductor interfaces is complex and not well characterized by current models for organic semiconductor interfaces. Specifically, I show that hybrid interfaces host unique electronic phenomena that depend sensitively on the surface structure of the inorganic semiconductor. I also demonstrate new applications of photoemission spectroscopies that enable the direct analysis of important properties of inorganic semiconductors, including charge carrier behavior near hybrid interfaces and the electronic character of defect-induced energy levels. The research presented here focuses on two different n-type inorganic semiconductors, tin disulfide (SnS₂) and zinc oxide (ZnO). SnS₂ is a layered transition metal dichalcogenide that presents an atomically flat and inert surface, ideal for sensitively probing electronic interactions at the hybrid interface. To probe the electronic structure of the SnS₂ surface, I used a variety of organic molecules, including copper phthalocyanine, vanadyl naphthalocyanine, chloro-boron subphthalocyanine, and C₆₀. ZnO has a complex surface structure that can be modified by simple experimental procedures; it was therefore used as a tunable semiconductor substrate where the effects of altered electronic structure can be observed. By carefully studying the origin of hybrid interfacial interactions, these research projects provide a first step in explicitly elucidating the fundamental mechanisms that determine the electronic properties of hybrid interfaces.

Texte intégralRésumé :
During the transitions from unicellularity to multicellularity, cells transitioned from functioning as wholes to functioning as parts of wholes. In the colonial freshwater green flagellates known as volvocine algae, living "intermediate form" species give ample evidence concerning how cells gradually lost autonomy and began functioning as dedicated parts. This dissertation concerns how and why the role of cell division changed in unicellular to colonial volvocine algae. We review a recent book on levels of selection and apply a proposed three-stage transition to the example of volvocine algae. We found that, in contrast to the previous description of "stage 1", the concept of group reproduction is potentially applicable to very early-branching colonial volvocine algae. This possibility indicates that the role of cell division could have shifted (to function in group reproduction) earlier than was previously thought (Appendix A). We show that, given some reasonable assumptions, cell- and colony-level fitness are equivalent in undifferentiated colonial volvocines (Appendix B). In spite of this, our models show that cell division number could evolve in response to specifically colony-level factors. Cell division number could be regulated indirectly via allocation to growth (Appendix B) or directly via regulation of the growth-to-first division transition (Appendix C). The extent to which group factors matter in the outcome of selection on cell division number is a matter of degree and is quantifiable (Appendix B). Colony cell number could be a genuine group-level adaptation, even in the simplest volvocine algae (Appendix B and C). Because a size-dependent growth trajectory is a substantial group-level cost of higher division numbers, our analysis highlights the potential importance of understanding how colony size affects cell growth (Appendix C). We also present data on cell-type allocation in Volvox (Appendix D). The Volvox colony is clearly the level of function for cell divisions and cell fate acquisition. However, this work indicates that the precision with which Volvox development attains these colony-level goals may be low compared to more complex multicellular organisms.

Texte intégralRésumé :
It is timely for hydrocarbon-dependent rentier states (countries) to transition to a low carbon economy, given the rapidly changing global energy landscape and increasing climate change mitigation pursuits. However, there is a lack of knowledge – particularly for small hydrocarbon-intensive states – about how to diversify and decarbonize. This thesis comprised a thorough analysis and synthesis of transition discourses, drivers, challenges, and barriers to enabling an immediate transition. Qatar was used a case study for exploration and sense-checking purposes. A ‘Transition Policy Framework’ was created to guide states who are fiscally dependent on energy exports, to create viable bespoke low carbon pathways.

Texte intégralRésumé :
Climate change policies are proliferating at a local and regional level. Within this landscape, organizational climate change action is shifting from voluntary to mandated, and organizations are grappling with new pressures to reduce their environmental impact. This dissertation explores organizational responses to climate change policy, though a field-level analysis of 132 organizations that were required to achieve carbon neutrality in British Columbia, Canada. The strategies organizations adopted or considered over a five-year period from the policy inception are examined using survey data and a content analysis of annual reports. This study shows that the organizations bound by the carbon neutral mandate quickly came to a common understanding of what the practical expression of carbon neutrality involved. Within five years of the policy introduction, and three years of the requirement to become carbon neutral, organizations were considering or adopting a large number of similar strategies in response to the legislative requirement to reduce their carbon emissions. This convergence of strategies can be explained by several factors. First, organizations drew cues about appropriate responses from the government, and from other organizations within the field, leading to isomorphism of strategies over time. Second, the organizations were working under a common set of institutional logics, or cultural assumptions about the rationale for pursuing strategies, leading them to consider the same practices appropriate for meeting carbon neutral goals. Finally, organizations were supported by similar networks of organizations, centralizing the field around a few key actors. Similarity in responses to the mandate to achieve carbon neutrality are reflective of the fact that organizations drew from the common sources of information and resources to meet emissions reduction targets.
This work demonstrates that organizational responses to climate policy should be understood with reference to the field in which organizations are embedded, rather than simply as the sum of individual organizational actions. It also highlights the fact that if the institutional and cultural conditions are right, organizational fields can rapidly emerge and adapt to new policy imperatives to tackle climate change.Arts, Faculty of

Texte intégralRésumé :
Women continue to be in the minority in school administration in public schools in the United States, although the majority of teachers are female. The role of assistant principal is the gateway to school administration. The purpose of this study was to describe the essence of the transition from teaching to school administration, the role of a female assistant principal, and the career aspirations of female assistant principals. This study used a phenomenological approach to understand the essence of the transition for the participants. Six women were interviewed using a semi-structured interview protocol to collect data on their experiences transitioning to the role of assistant principal. Using the process of horizonalization, the data were transcribed and analyzed using statements and quotes from the interviews to develop themes common to all participants. Findings revealed that these women continually seek to better themselves, others, and their organizations. They experienced a significant sense of loss as they transitioned to their new role. Lastly, the supports needed by women as they continue in their career as school administrators were uncovered.
