Full textAbstract:
Problem - The challenge investigated in this present study is for a project-based organization to create a well-planned implementation by knowing the current state of the organization and its readiness for a change. This while also taking the time for unexpected events and communicating the issue while also taking their organizational structure into consideration. Purpose - The purpose of this study is to analyze the readiness to change for the case company with focus on three aspects of readiness: information sharing, common views and implementation approach, while also taking into account the distinct features of a PBO-structured organization. The study aims to identify supporting factors for successfully managing an implementation of a new business system at the individual level. Method - This study is a case study based on a single case company: Sweco, which is a Swedish technical consulting firm that is about to change their business system. A literature review was conducted in order to collect previously conducted research within the research area. The primary methods used for data collection in this study have been semi-structured interviews and a questionnaire, the data was mainly analyzed though thematic analysis. Results – The readiness for change for the case company is affected by their organizational structure. The results of the questionnaire show that collaboration within Sweco works relatively well, but there are some aspects that can be improved, such as communication and information sharing. The results of the conducted interviews show that most employees at the case company perceive the change of business system to be good, but they were unsure about why it would be carried through. Guides on how the change would affect the specific individual and knowing where to turn for feedback and information was pointed out as a suggested improvement by the employees. A lot of responsibility of implementing the new system was put on the unit managers. Conclusions - The study strengthens the existing theory regarding change readiness and individual supporting factors for successful change implementation. It confirms some of the strengths and drawbacks for organizations working with projects. The study also concludes how the case-company and other companies in a similar situation can utilize some advantages of being familiar with working in projects.

Full textAbstract:
The purpose of this study was to investigate the relationship between teachers&rsquointentional, emotional, and cognitive readiness for change and perceived faculty trust in colleagues, in principal, and in clients (students and parents).The study was designed as a correlational study and the participants comprised of 603 teachers working at primary and secondary level public schools selected from the four school districts in Ankara via cluster sampling. For the data collection, newly developed Readiness for Change Scale and Turkish adaptation of Omnibus T-Scale were utilized. Both descriptive and inferential statistics techniques (Canonical Correlation) were used for the data analysis. Confirmatory factor analysis for Readiness for Change Scale and Omnibus T-Scale were also performed within the scope of this study. Descriptive and inferential statistical analyses were performed by the software PASW Statistics 18 while the confirmatory factor analysis was performed by the software AMOS 4. The results of the study revealed that teachers&rsquo
readiness for change and perceived organizational trust were significantly correlated with each other in a way that intentional, emotional, and cognitive readiness for change were all associated with teachers&rsquo
readiness for change and contributed significantly in perceived organizational trust. Conversely, the results indicated that perceived faculty trust in colleagues, in principal, and in clients (students and parents) are all correlated with perceived organizational trust, and contributed significantly in teachers&rsquo
readiness for change. Consequently, the results of this study revealed that organizational trust is an essential internal context variable, which is correlated with teachers&rsquo
readiness for change. In this respect, the decision-making body of educational organizations, MONE, and schools should undertake necessary precautions to empower trust-based relationship within the teacher, principal and client (students and parents) triangulation for effective implementation and desired outcomes of the change interventions.

Full textAbstract:
Academic enablers comprise a set of beliefs and skills that significantly contribute to student success. Although these skills are crucial to academic competence, gaps exist in the research related to the development of academic enablers. Namely, previous research has not investigated how these behaviors change over the kindergarten year. Moreover, there are inconsistent findings regarding the influence of experiences prior to entering kindergarten, specifically preschool attendance and the home learning environment, on the development of academic enablers in young students. Using a sample of 83 parent-child dyads, the present study investigated academic enablers in kindergarten students. A mixed between-within analysis of variance found that girls displayed greater academic enablers at the beginning of the kindergarten year, but neither gender demonstrated growth over the kindergarten year. Additionally, hierarchical multiple regression analyses were run to determine whether environmental factors predicted academic enablers at the beginning and end of kindergarten. Findings indicated the length of preschool experience did not predict adaptive academic enablers at the beginning of the kindergarten year or the end of the year, regardless of gender. Conversely, the home learning environment predicted kindergarten students' levels of academic enablers at the beginning of the year, such that those with educationally enriched home environments displayed higher levels of academic enablers, regardless of gender. This influence was not maintained over the kindergarten year. Implications for practice and future research are discussed.

Full textAbstract:
Many organizations aspire to adopt agile processes to take advantage of the numerous benefits that it offers to an organization. Those benefits include, but are not limited to, quicker return on investment, better software quality, and higher customer satisfaction. To date however, there is no structured process (at least that is published in the public domain) that guides organizations in adopting agile practices. To address this situation, we present the Agile Adoption Framework and the innovative approach we have used to implement it. The framework consists of two components: an agile measurement index, and a 4-Stage process, that together guide and assist the agile adoption efforts of organizations. More specifically, the Sidky Agile Measurement Index (SAMI) encompasses five agile levels that are used to identify the agile potential of projects and organizations. The 4-Stage process, on the other hand, helps determine (a) whether or not organizations are ready for agile adoption, and (b) guided by their potential, what set of agile practices can and should be introduced. To help substantiate the â goodnessâ of the Agile Adoption Framework, we presented it to various members of the agile community, and elicited responses through questionnaires. The results of that substantiation effort are encouraging, and also suggest further avenues for improvement.Ph. D.

Balestrucci, Federica. "Transition towards circular economy through a multi-readiness level model : An explorative study in the construction equipment industry." Thesis, Mälardalens högskola, Akademin för innovation, design och teknik, 2020. http://urn.kb.se/resolve?urn=urn:nbn:se:mdh:diva-49306.
Full textAbstract:
Circular economy is considered one of the most viable approaches to sustainability and it has gained a lot of traction in recent years. It challenges the linear approach to production and consumption that generates waste and is unsustainable for the planet and future generations. It is crucial to counteract the negative impacts of production on the environment by implementing new and effective business strategies that are compatible with circular economy. Nowadays, manufacturing industries are struggling to make the transition towards circularity because of the intrinsic complexity of adapting new business models, product development, production processes and supply chain management to a non-linear approach. The literature on the transition towards circular economy extensively covers the aspects connected to either one of the above-mentioned domain-specific areas, developing different tools such as roadmaps and frameworks to support companies in the transition for a specific area. Yet, there is a lack of a systematic tool that can give support in each stage of the process based on the different business areas that need to be adapted to circularity. The purpose of this study is to explore the existing state-of-the-art knowledge with a systematic and holistic approach to factors that are connected to circular economy, so to create a practical tool for facilitating the process of transitioning towards circularity in a step- by-step manner, in connection to activities and strategies that can be implemented in different business domains. An explorative case study in a manufacturing company in the construction equipment industry was carried out, with a twofold purpose: firstly, to gather, analyse and frame the existing state-of-the-art knowledge on the implementation of circular economy. Secondly, to explore the suggested multi readiness level model with the case study company in order to validate it. In order to do so, a set of ten semi-structured interviews with senior managers and experts in the field was carried out to gather valuable insights and practical knowledge. The outcome of this study is a multi-readiness level model for transitioning towards circular economy that explores the most important strategies and activities that should be implemented by a manufacturing company in four different areas of intervention, namely Ecosystem of External Partners, Customer and Business model, Company’s Culture and Internal Capabilities and Design and Product Development. Each area of intervention will be presented in connection to identified strategies and activities that must be implemented to reach circularity.

Samuels, Richard. "A multi-level perspective analysis of the change in music consumption, 1989-2014." Thesis, Cardiff University, 2018. http://orca.cf.ac.uk/116065/.
Full textAbstract:
This thesis seeks to examine the historical socio-technical transitions in the music industry through the 1990s and 2000s which fundamentally altered the way in which music is consumed along with the environmental resource impact of such transitions. Specifically, the investigation seeks to establish a historical narrative of events that are significant to the story of this transition through the use of the multi-level perspective on socio-technical transitions as a framework. This thesis adopts a multi-level perspective for socio-technical transitions approach to analyse this historical narrative seeking to identify key events and actors that influenced the transition as well as enhance the methodological implementation of the multi-level perspective. Additionally, this thesis utilised the Material Intensity Per Service unit methodology to derive several illustrative scenarios of music consumption and their associated resource usage to establish whether the socio-technical transitions experienced by the music industry can be said to be dematerialising socio-technical transitions. This thesis provides a number of original empirical and theoretical contributions to knowledge. This is achieved by presenting a multi-level perspective analysis of a historical narrative established using over 1000 primary sources. The research identifies, examines and discusses key events, actors and transition pathways denote the complex nature of dematerialising socio-technical systems as well as highlights specifically the influence different actors and actor groups can have on the pathways that transitions take. The thesis also provides a broader contribution to the understanding of dematerialisation and technology convergence.

Full textAbstract:
The aim of this thesis is to create a tool which quantifies qualitative measures into an indicator system. The system is created on behalf of a company which is associated with investments in new technologies on the energy market. The indicator system is to take into consideration important factors in the first part of an investment cycle, in other words, the screening phase. Qualitative measures will, in each indicator, become quantified and will together create a weighted grade on a potential investment that can help the investor decide whether or not to move forward with said investment. The aim of the thesis is also to evaluate the indicator system on current possible investment options in order to analyse and discuss how the final product will work in the investor company ́s actual context. The method consists of two main parts, a gap analysis which is conducted within the investor company and its owners and a compilation of which indicators that are of greatest importance in a screening phase according to earlier research. The main result of the study is the full indicator system which consist of four indicators: technology readiness of the potential investment, contextual analysis of the potential investment, diversity within the company and the financial burn rate of the company. When applied to current potential investments the result showed that there was negligible to moderate correlation between the indicators, which was important for the system to be validated. It was also concluded that a potential investment should exceed 60 percent of the possible maximum grade in order to pass through the screening phase. The results also showed that there were four apparent gaps, namely consensus between the involved actors, utilization rate of the organizations competencies, to enter new markets and the right competency to do so. The future potential investments of the investor company should therefore aim to fill in these gaps in order to strengthen the role of the company. If doing so while using the indicator system, the risks of choosing investment options that does not fit into the investor company ́s context, will be minimized.

Silveira, Fabrício. "Industrial allocation and growth trajectories : a multi-level approach." Thesis, University of Cambridge, 2019. https://www.repository.cam.ac.uk/handle/1810/290074.
Full textAbstract:
This dissertation investigates the process of economic growth with heterogeneous agents from a multi-level perspective. Building upon Kaldorian and Evolutionary principles, growth is defined as a path-dependent and complex phenomenon, which requires structural variation and the interplay between demand and supply at distinct analytical levels. Two concomitant and dependent 'layers' of this process are emphasised: the supply-led 'intra-sectoral development trajectory' and the demand-led 'inter-sectoral development trajectory'. The key element in the first is the firm size, which is shown to have a non-linear influence on the process of technological change. The second layer is shown to depend on the growth of income and patterns of production and consumption reflected on the inter-sectoral composition and level of 'sophistication' of the productive structure. The key to understand divergent growth trajectories lies in the interaction between these layers and the contradictory effects imposed at each analytical level both by demand (top-down) and supply (bottom-up). The approach is both theoretical and empirical and the analysis reveals important stylised facts of growth at the firm, sector and country levels. The text is structured in four sections comprising 9 chapters. Section I introduces the theoretical foundations of the work and the limitations of Evolutionary and Kaldorian schools to explain the multi-level 'allocation problem'. Section II presents the databases and empirically assesses the influence of the (re)allocation of labour on growth at each analytical level. Section III investigates the foundations of the process of micro-meso and macro process of development. The final section proposes a unified theoretical framework to connect the multi-level evidence. The analysis reinforces the interplay between demand and supply in growth trajectories, prompting a number of original policy implications.

Full textAbstract:
Humans have the ability to synchronise with sounds divided by equal intervals and predict when the next sound is coming, as opposed to reacting to them. By creating a pulse within ourselves based on these recurrent sounds we are able to, for instance, play music and dance. A stable pulse can be maintained accurately even without external stimuli for up to about two seconds. Previous research showed that this limit could be extended to about eight seconds if the pulse was supported by a sound pattern with a facilitating temporal structure, which also seemed to be slowing down infinitely. The present study used the same type of multi-level pattern, but with longer playing time and stricter instructions for the participants. Just as in the seminal study the participants had to hit a drumstick against a drum pad according to their inner representation of the pulse when hearing the stimuli, for both increasing and decreasing tempi. In addition, the present study featured four different rates of tempo change. The results showed that the produced time interval could be extended to around 16 seconds for decreasing tempo with the slowest rate of change.Människor har förmågan att synkronisera med ljud separerade av lika långa tidsintervalleroch förutse när nästa ljud kommer, istället för att bara reagera på dem. Genom att skapa en inre puls baserad på dessa återkommande ljud kan vi till exempel spela musik och dansa. En stabil puls kan upprätthållas även utan externa stimuli i upp till omkring två sekunder. Tidigareforskning visade att denna gräns kunde förlängas till omkring åtta sekunder om pulsenstöddesav ett ljudmönster med en underlättande temporal struktur, som också verkade sakta ner i oändlighet. Den aktuella studien använde sig av samma typ av stimuli, men med längre speltid och striktare instruktioner till deltagarna. Precis som i den första studien var deltagarnas uppgift att slå en trumstock mot en trumplatta baserat på deras inre representation av pulsen när dom hörde stimulit, för både ökande och avtagandetempo. Dessutom så innehöllden aktuella studienfyra olika grader av tempoändringar.Resultaten visade att det producerade tidsintervallet kunde ökas till nästan 16 sekunderför avtagandetempo med den långsammaste graden av ändring.

Full textAbstract:
Cette thèse questionne la financiarisation du régime d’accumulation en Corée du sud après la crise asiatique de 1997 à partir de l’observation des changements macroéconomiques et institutionnels importants poussés par l’adoption de politiques néolibérales ; de l’insertion croissante des entreprises dans les marchés financiers et commerciaux internationaux ; de la refonte du rôle de l’État pour promouvoir les secteurs intensifs en technologie. Le cadre conceptuel et les outils analytiques de la théorie de la Régulation, combinés à ceux de l’économie post-keynésienne, sont mobilisés pour envisager ces transformations de manière systémique, à plusieurs niveaux et à plusieurs échelles. Le travail de thèse discute les moteurs et les vecteurs qui participent à la financiarisation de l’économie politique sud-coréenne et les caractéristiques locales de ce processus global, intrinsèquement inégal et hiérarchique. • Le chapitre 1 De l’industrialisation à la financiarisation pose les jalons de la thèse en étudiant la dynamique macroéconomique contemporaine à la lumière des transformations politiques et institutionnelles depuis l’industrialisation. A partir d’une estimation du régime de demande en vigueur de 1980 à 2015, il est montré que le régime d’accumulation dominé par la finance qui se met en place après 1997 est tiré par le profit et entraîné par la consommation. • Le chapitre 2 Financiarisation le long des chaînes de valeurs examine la chute structurelle de l’investissement des entreprises manufacturières sud-coréennes en considérant le rôle de trois canaux de la financiarisation (effet d’évincement et fardeau financier) auxquels est rajouté le canal de l’intégration internationale des firmes dans les chaînes globales de valeurs (CGV). Une fonction d’investissement incluant ces trois canaux est estimée économétriquement sur données de firmes (1990-2015). Les résultats indiquent que l’effet des canaux de la financiarisation dépendent des modalités d’insertion des firmes dans les CGV.• Le chapitre 3 La répercussion contrastée de la financiarisation sur les capacités de l’État se concentre sur les transformations institutionnelles et organisationnelles au sein de l’État liées à la financiarisation. A partir d’un travail de terrain sur les politiques de promotion des start-ups, un mécanisme de changement institutionnel au sein de la structure étatique est identifié, celui de sédimentation. En promouvant les start-ups via l’industrie du capital-risque, les agences d’État tendent à adopter les pratiques et représentations du secteur financier, ainsi qu’à donner plus de poids aux acteurs financiers privés, ce qui pèse sur ses capacités d’innovationThis thesis examines the financialization of the accumulation regime in South Korea since the 1997 Asian crisis based on three inter-related transformations: macroeconomic and institutional changes under the neoliberal restructuring; the growing integration of firms into financial and trade markets; the restructuring of the role of the state under the drive to promote technology-intensive sectors. Building upon regulation theory and post-Keynesian economics, the analysis considers several levels—macroeconomic, institutional and political, and different scales—local, national, transnational. The thesis discusses the determining drivers and the conduits of the financialization of the South Korean political economy and the local characteristics of this global process, conceptualized as intrinsically uneven and hierarchical • Chapter 1 From industrialization to financialization analyzes the joint transformation of the macroeconomic trend, institutional change, and political change since industrialization. Based on the estimation of the demand regime(s) from 1980 to 2015, it is highlighted that the finance-dominated accumulation regime that has emerged after the 1997 Asian crisis is consumption driven and profit led. • Chapter 2 Financialization along value chains investigates the slowdown of accumulation of South Korean manufacturing firms by assessing the impact of three channels, the crowding out of fixed investment by financial investment, the financial burden of increasing payments to financial markets, and the modes of insertion to global value chains (GVCs). A dynamic panel model of an investment function is estimated on firm-level data (1990–2015). The results show that the impact of financialization channels depends on the modalities of firms’ insertion into GVCs. • Chapter 3 The uneven impact of financialization on state capacities examines the institutional and organizational transformations of the state associated with the financialization process. Based on semi-structured interviews in the start-up ecosystem, the layering mechanism of gradual institutional change within the state innovation bureaucracy is identified. The results outline a complex picture of the financialization of the state with the combination of the uneven diffusion of financialized reasoning in the innovation bureaucracy via entrepreneurship policies and the localized power shift from bureaucrats to private financiers

Full textAbstract:
This thesis questions the contemporary perception of climate change governance as a purely international responsibility, to be primarily addressed by multilateral negotiations of nation states. An engagement with the geographic theory of scale demonstrates sub-national governments' (SNG) role in the governance of local causes and effects of climate change. SNG networks are an emerging actor in climate change governance, as SNGs have grouped together to tackle climate change collectively. This thesis considers the value of these SNG networks in influencing the laws and policies of their members, as well as the international regime. More broadly, the membership of SNG networks suggests that the role of these networks in a multilevel governance regime is to "fill the gap" of support for regional and city governments that are undertaking more ambitious climate change action than the national governments in which they reside.Ce mémoire questionne la perception contemporaine de la primauté des négociations multilatérales, qui ont pour but de lutter contre le changement climatique. La théorie géographique de l'échelle illustre que les villes, les provinces et les régions – les gouvernements sous nationaux – jouent également un rôle dans la gestion des causes et des effets locaux du changement climatique. Les réseaux, créés par les gouvernements sous nationaux, sont en train de devenir des acteurs majeurs dans la gouvernance du changement climatique en raison du regroupement de ces gouvernements afin de traiter de la question collectivement. Ce mémoire étudie l'importance de ces réseaux; en particulier, leurs influences sur les lois et la politique des gouvernements sous-nationaux, ainsi que sur le régime international de l'Organisation des Nations Unis. De plus, l'adhésion des réseaux suggère que le rôle de ces réseaux au sein d'un régime à plusieurs niveaux est de mettre fin aux lacunes qui existent dans le soutien des gouvernements régionaux et des municipalités, qui ont entrepris des projets pour la lutte contre le changement climatique plus ambitieux que les gouvernements nationaux dans lesquels ils se situent.

Full textAbstract:
This thesis presents a multi-proxy reconstruction of Holocene sea-level change at the Steart Peninsula in Bridgwater Bay, Somerset. Single- and multi-proxy transfer functions were developed from diatom and foraminifera training data from two sites on the Severn Estuary coast. Constrained and partial constrained ordination estimated that 5.5% of the intertidal diatom variation and 11.4% of the intertidal foraminifera variation in the training sets was explained independently by elevation within the tidal frame. Foraminifera provided more favourable transfer function prediction statistics but were low in abundance in parts of the intertidal zone, resulting in a smaller than optimal training set. The preferred transfer function combined diatom and foraminifera data to optimise prediction statistics and intertidal coverage. An 11.22m fossil core was retrieved from the Steart Peninsula for stratigraphic and micropalaeontological analyses. Analogue matching revealed that combining the two proxies increased the number of fossil samples with good or fair modern analogues in relation to the single proxies separately. The preferred multi-proxy transfer function was applied to the fossil micropalaeontological data. The sediment stratigraphy, biostratigraphy and transfer function-based estimates indicated an overall rise in relative sea-level of about 13m between 7,582-7,345 and 1,804-1,690 cal. years before present (cal. yr BP), beginning with an initial rapid phase of sea-level rise and silty clay deposition in a minerogenic saltmarsh environment. Between 6,188-6,007 and 3,942-3,759 cal. years BP three main fluctuations in marine influence occurred, allowing organic upper saltmarsh conditions to develop periodically, but the data scatter and large vertical error bars prevent a detailed interpretation of absolute sea-level change. Diatoms and foraminifera were sparse or absent between 4,053-3,869 and 1,927-1,806 cal. years BP. Finally, foraminifera assemblages indicated a possible tidal flat environment and increase in marine influence between 1,927-1,806 and 1,682-1,619 cal. years BP. This research concludes that multi-proxy methods have the potential to improve the accuracy and precision of relative sea-level reconstruction in an extremely macrotidal setting such as that of the Severn Estuary, but that a number of issues such as sediment autocompaction and possible Holocene tidal range changes need to be quantified in order for the broad sea-level history presented to be constrained further.

Full textAbstract:
The thesis explores issues relating to transformative change in the context of marine governance in the Coral Triangle, and the effects of such change processes on policy, stakeholder relations and management activities. Paper 1 studies how change-oriented actors (institutional entrepreneurs) operating at the international level can introduce and purposefully navigate large-scalechange processes. Paper 2 studies the impact of resource inequality on multi-stakeholder collaboration, and tackles the literature of boundary work so as to increase its usefulness for understanding complex, multi-level governance initiatives. Paper 3 explores how narratives about the marine environment are entwined with and influence critical aspects of marine ecosystem governance such as resource allocation, day-to-day management actions, stakeholder relations, and long-term ecological monitoring. Paper 4 investigates how actors at the local level can capture opportunities at higher institutional levels while at the same time catalyzing local potential for change by focusing on the interplay between strategies,opportunity and context. The results show that institutional entrepreneurship requires understanding of how strategies can be matched with opportunity and context, for example by offering a way for other actors to address key priorities and add value to their organizations. The results also show that behind the scene organizing is often a precondition for the introduction of transformative change. Shifting the process from an informal track to a formal track where ideas about transformative change can be deliberated among a broader set ofstakeholders is thus a major challenge. Moreover, a strong narrative is key to successfully introducing and driving transformative change. In this sense, the ability to articulate and distribute a narrative which tells a compelling story about the broader system is critical. Finally, power dynamics are constantly at play in transformation processes due to resource asymmetries. The thesis shows that differences in resources may influence the credibility, legitimacy, and salience of transformative change.At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 2: Submitted. Paper 3: In press.

The last few years have seen one of the most severe droughts in recent times in the southern African region, and news headlines are increasingly full of warnings about heavy storms, fires and floods. There is no doubt that extreme hydro-meteorological events, and their multiple and potentially disastrous impacts, are at the forefront of the public consciousness at the present time and are one of the key concerns regarding the impacts of climate change in the region. While the links between extreme climate events, disaster risk reduction (DRR - see Box 1) and climate change adaptation (CCA - see Box 2) are recognised in the South African Climate Change White Paper, this is not the case for the whole region. Furthermore, even if there is national recognition of the need to synergise these two spheres of endeavour, this does not always trickle down to effective policy, planning and implementation at the local level.

Full textAbstract:
The study of health disparities and the social determinants of health has resulted in the call for public health researchers to investigate the mid- and upstream factors that influence the incidence of chronic diseases (Adler & Rehkopf, 2008; Berkman, 2009; Braveman P. , 2006; Braveman & Gottlieb, 2014; Krieger, 2011; Rose, 1985). Social ecological models (SEMs) provide important conceptual tools to inform this research and practice (Krieger, 2011; Golden & Earp, 2012; Story, Kaphingst, Robinson O'Brien, & Glanz, 2008; Glanz, Rimer, & Lewis, 2002). These models can help us look at the social and physical environments in rural Arizona communities and consider how health policies and environmental interventions address mediating factors, such as disparities in access to fresh food, that contribute to ill health in marginalized, rural, populations. Rural residents are at greater risk for obesity than their urban counterparts (Jackson, Doescher, Jerant, & Hart, 2006; Story, Kaphingst, Robinson O'Brien, & Glanz, 2008). And while human life expectancy has steadily increased over the past thousand years, current projections indicate that the rise in obesity-related illnesses will soon result in its decline (Olshansky, et al., 2005). One reason for this decline, may be the reduced availability of healthy food – an important predictor of positive health outcomes including reduced obesity and chronic disease - in many parts of the United States (Brownson, Haire-Joshu, & Luke, 2006; Ahen, Brown, & Dukas, 2011; Braveman & Gottlieb, 2014; Braveman, Egerter, & Williams, 2011). The United States Department of Agriculture (USDA) defines food deserts as geographic areas in which there is limited access to grocery stores and whose populations have a high rate of poverty. In Arizona, 24% of the rural census tracts are considered food deserts; compared to an average of eight percent of rural census tracts across the nation (United States Department of Agriculture, 2013). Food deserts are one example of the upstream factors influencing the health of rural populations.
Local health departments have been encouraged through the National Association for City and County Health Officials (NACCHO) and through the Public Health Accreditation Board (PHAB) to conduct community health assessments (CHAs) in order to identify unique contexts and community resources, health disparities, and the social determinants of health as well as potential areas for advocacy, policy change, environmental interventions, and health promotion interventions. Public health challenges like chronic diseases, which have multiple causes, can be explored in-depth through CHAs. CHAs often contain recommendations for action and/or are followed by community health improvement plans (CHIPs) which help local health departments prioritize resources and set measurable goals. In Florence, AZ recommendations made in a CHA are being acted upon by a non-profit agency, the Future Forward Foundation (3F). This investigation explores two interrelated issues regarding the use of CHAs and CHIPs as practical tools to set public health priorities. First, what makes a CHA useful to rural public health practitioners? What methods of conducting a CHA and subsequently analyzing the data results in actionable policy recommendations and/or environmental level interventions? Second, to what extent can public health agencies engage nontraditional partners to work in partnership to address the social determinants of health? As an example, I will look at the impact of a volunteer-based non-profit agency, located in a rural food desert on improving the social and physical nutrition environment as recommended by a local CHA. This inquiry will provide insights to public health practitioners seeking to identify and implement policy and environmental change addressing complex, multi-causal, public health issues, and provide insights regarding engaging nontraditional partners who may not self-identify as public health agencies.

Full textAbstract:
The Sefidrud has developed a large delta in the south west of the Caspian Sea. Its delta is characterized by rapid sedimentation rate (20 mm/yr) in the delta plain and low sedimentation rate (1.67 mm/yr) in a very steep delta front. Sefidrud Delta evolution depends upon sediment supply by river and longshore current under rapid Caspian Sea Level (CSL) fluctuation and tectonic setting at the point of entry to the basin. The tectonic setting caused a very steep slope in the delta front. Sediment supply is variable and affected by river avulsion and dam construction. The CSL has undergone significant changes during the last millennium. Therefore, the Sefidrud Delta evolution during the last millennium is explained based on CSL fluctuations. This fluctuation has major impacts not only on coastal lagoons, but also more inland in wetlands when the CSL rose up to at least -21.44 m (i.e. >6 m above the present water level) during the early Little Ice Age. Although previous studies in the southern coast of the Caspian Sea have detected a high-stand during the Little Ice Age period, this study presents the first evidence that this high-stand reached so far inland and at such a high altitude. This study also examines the interdependence of different factors in the evolution of coastal lagoons as a part of delta evolution. Dam flushing operations and rapid sea–level rise (~3 m between 1977 and 1995) have accelerated the infilling of the coastal lagoon system. This rapid infilling (31 mm/yr) makes the whole system more prone to sediment encroachment in the short term. Because the lagoons are short-lived and have dynamic evolution, the impact of the Anthropocene is also visible in the delta evolution.

Full textAbstract:
Sustainable transportation solutions are the goal for the future. With the technological shit happening in the transportation market towards electric vehicles, the electric road system (ERS) is a necessary technology required to reach the sustainability goals for the future. While many studies show the role of innovation in a socio-technical landscape, many neglect the diffusion process of the innovation which occurs to create a socio-technical change. The nature of this thesis is an exploratory case study with a qualitative approach. To address the study, a literature review for the diffusion of innovation, its characteristics, multi-level perspective, and technology readiness level (TRL) was presented in order to provide a better understanding and build a foundation for the research. A review of scientific articles regarding the electric road system was performed to provide insights and obtain information on the technology. The data from scientific articles were complemented by interviews from experts regarding electric road systems to obtain an understanding of technology if it was to be implemented in the future in Sweden. The empirics collected were analyzed using the literature framework and conclusions were drawn. Analyzing the data was required to find the factors hindering the technology and if there is a window of opportunity for the technology to exist in the Swedish market. Environmental sustainability has been the driving factor, but the rate of diffusion for the technology will depend on the complexity and the maturity of the technology to function as a whole working system. The study contributes to evaluating the implementation of an inductive electric road system in the Swedish context and if it could be a viable solution in the transportation market. The perspectives of the technology in the Swedish market and the motivation for the solution are discussed. An analytical contribution by evaluating if the technology could exist in the future and insights on the diffusion of the technology into the existing landscape.

Full textAbstract:
This study investigates the team aspects of a process improvement project situated in an Internet banking system maintenance and modification phase. To investigate how team processes could be improved in this context, four interventional change techniques were introduced and implemented during an action research study in which the researcher was included as one of the team members and participated during group meetings and discussions. Internet banking is an important Internet-delivered service which is expected to provide benefits for both commercial banks and bank customers. Internet banking allows bank customers to have the freedom to perform their financial activities at their convenience. Developing, maintaining, and improving Internet banking systems requires large amounts of investment to maintain high levels of Internet banking service quality, and the maintenance and modification phase of the overall lifecycle cost is a considerable part of this investment. Therefore, in order to ensure high levels of usability, reliability, and quality for these Internet banking services, commercial banks need to make significant investments in the maintenance and modification phases of their Internet banking systems' lifecycle. The four interventional change techniques used in this study were: departmental participation, equal participation, holistic scenario, and management support. The four techniques were found to be influential in developing process improvements in the maintenance and modification phase of Internet banking systems. These techniques generated several significant improvements which directly affected the way team members managed their work. The significant contributions of these interventional change techniques were: the creation of cross-functional multilevel teams, development of effective departmental participation and communication techniques, extended scope and knowledge by the team members of Internet banking systems, an increase in team learning and understanding, techniques to change problem structure, and an end to end problem-solving approach. ii These contributions also directly improved the performance of the Internet banking systems maintenance team, and there was a significant improvement in the outcomes of the Internet banking systems maintenance and modification phase.

Full textAbstract:
This thesis takes a critical examination of current theories of the emergence of reindeer herding, during the sixteenth and seventeenth century, amongst Sami communities in northern Sweden. This period coincides with the latter part of the Little Ice Age, a period of extremely variable climate in northern Europe, which has not been addressed in current theories of the emergence of herding. Using a bottom-up approach, gathering evidence of the nature of the environmental change and its impact on reindeer, human populations, and subsistence activities, it is suggested this had a profound effect on subsistence strategies. These impacts are considered in context to provide a multi-causal model of cultural change during this period. The evidence suggests that reindeer herding did not represent a radical and large-scale cultural change, and that Sami subsistence strategies do not fit neatly into categories of hunting or herding. The intensification of reliance on domestic reindeer emerged, from the preceding mixed economy, as a high-level buffering mechanism to cope with increased local environmental variability and a disruption In the wild reindeer popUlation, and was facilitated by interactions with the Swedish state through trade and taxation.

Full textAbstract:
The phenomenon of climate change is widely recognized and declared as the single most threatening issue of the 21st century (UN Environment, 2018). In this context, the presented study is aligned with scientific research on the domain of sustainable development and sustainability transitions aiming to counterbalance climate change and its impact on this planet as much as possible. This research focuses on Green Bonds as a financial tool to promote this kind of climate-resilient transition. Professionals from the financial sectors of the Swedish Green Bond market were interviewed, reflecting current opinions and strategies of one of the most developed and progressive nations in the world. The goal is to understand the dynamics behind the development of the Green Bond market using the Multi-Level Perspective framework and to find out to what extent these experts view Green Bonds as a tool in the process of sustainability transitions. The findings firstly point out the role of the different actors of the Green Bond market, describing the interactions between investors, issuers banks, politics and advisors. In addition, the results show that the opinions on drivers and barriers amongst the interviewees and between the interviewees and literature differ somewhat. In particular, greenwashing, lacking transparency and missing standardization are seen by some of the different interviewed stakeholders to be less barriers but rather as opportunities. In conclusion, this study points out the particular influence that politics, as representant of the strongly environmentally aware people of Sweden, occupy in steering the market’s development and describes its importance as regulatory drivers of Green Bonds as a tool for sustainability transitions and sustainable development.Mänskligheten står inför en global utmaning; att kollektivt bekämpa den mänskligt orsakade klimatförändringen (UN Environment, 2018). Det är från detta sammanhang som denna studie ursprungar, där teorier inom vetenskaplig forskning för området hållbarhetsutveckling och hållbarhet förändringar används för att bekämpa klimatförändringens inverkan. Denna forskning fokuserar särskilt på gröna obligationens roll för en hållbar klimatrelaterad utveckling i det svenska samhället. För att utvärdera den svenska marknaden för gröna obligationer intervjuades experter inom området utvalda på basis av post och sektor. Målet med en kvalitativ forskningsmetod är att förstå de bakomliggande faktorerna för den progressiva utvecklingen i Sverige. Detta görs ytterligare genom ”The Multi-Level Perspective framework” för att kontextualisera experternas insyn på hur gröna obligationer kan användas som verktyg för hållbarhetsutveckling. Kartläggningen användes för att beskriva dynamiken mellan obligations utfärdaren, investerare, banker samt rådgivare i Sverige. Intervjuerna visade på nyanser inom dagens teori och praktik avseende hur man utvärderar tillväxten på den gröna obligationsmarknaden och framförallt gällande integritet faktorer som standardisering och transparens. Ett bristande ramverk kan ses som en möjlighet för tillväxt istället för ett hinder. Sammanfattningsvis understryker undersökningen politikernas inflytande för att kunna omvandla gröna obligationer från en nisch till en standardprodukt i samhället. Detta påvisar effektiviteten inom den svenska gröna obligationsmarknaden, där hög grad av miljömedvetenhet hos befolkningen blivit representerad i politiken.

Full textAbstract:
Les changements climatiques et l'émission de polluants dans l'environnement sont susceptibles d'entrainer des effets croisés sur les communautés et le fonctionnement des écosystèmes. Les changements de température sont notamment susceptibles de modifier le comportement et la toxicité des polluants, et de sensibiliser les organismes aux stress chimiques. Inversement, l'exposition à des polluants peut diminuer la tolérance thermique des espèces ectothermes comme les poissons. Dans ce contexte, nous avons étudié la réponse d'une espèce modèle de poissons en toxicologie aquatique, le Carassin doré (Carassius auratus), soumis à des stress chimique et thermique individuels et combinés. Pour cela, le carassin doré a été exposé à un cocktail d'herbicides et de fongicides à des concentrations réalistes d'un point de vue environnemental à deux températures pendant 96h ou 16 jours. Les réponses ont été observées de l'échelle moléculaire à l'échelle individuelle par des approches omiques (protéomique et métabolomique), biochimiques (cortisol, biomarqueurs de stress oxydant et allocation cellulaire énergétique), indicielles (indices somatiques et de condition) et comportementales (remaniement sédimentaire, activité, exploration et comportement alimentaire). Les résultats montrent que l'exposition des poissons aux stress chimique et thermique individuels entraine une réponse générale de stress impliquant des compensations biochimiques, énergétiques, physiologiques et comportementales. L'absence d'effets sur la santé générale des carassins suggère la mise en place d'une réponse de stress efficace et adaptée, bien que l'hypoactivité observée chez les poissons exposés aux cocktails de pesticides soit susceptible d'entrainer une diminution de leurs performances et de leur fitness. A l'inverse, les carassins exposés aux stress chimique et thermique combinés montrent une inhibition de la réponse générale de stress, avec des effets antagonistes sur la sécrétion de cortisol, l'induction de certains systèmes de défense antioxydants et la compensation énergétique. Des effets plus importants sont en revanche observés au niveau comportemental ainsi qu'une diminution significative de la condition générale des poissons. Ces résultats montrent que l'augmentation de la température sensibilise les poissons à la contamination de l'eau par les pesticides. L'inhibition de la réponse de stress chez des poissons exposés à des mélanges complexes de pesticides dans un écosystème soumis à de multiples contraintes pose de nombreuses questions pour la conservation des espèces dans l'environnementCrossed-effects between climate change and chemical pollutions were identified on community structure and ecosystem functioning. Temperature rising affect the toxic properties of pollutants and the sensitiveness of organisms to chemicals stress. Inversely, chemical exposure may decrease the thermal tolerance of ectothermic species, as fish. In this context, we studied the response of a biological model in aquatic toxicology, the goldfish (Carassius auratus), to individual and combined chemical and thermal stresses. In this aim, we exposed the goldfish to environmental relevant concentrations of herbicide and fungicide mixtures at two temperatures for 96 hours or 16 days. The fish responses were assessed from the molecular level to individual endpoints, including omic approaches (proteomic and metabolomic), biochemical analyses (cortisol, antioxidant defenses, cellular energy allocation), indexes (somatic and condition factors) and behavioral assays (sediment reworking, activity, exploration and feeding). Our results showed that individual chemical or thermal stresses induced a general stress response including biochemical, metabolic, physiological and behavioral compensations. The absence of deleterious effect on the global condition of fish suggested the implementation of an efficient and adaptive stress response, while the hypoactivity of fish exposed to pesticide mixtures could entrain a decreased performance and fitness into the wild. At the opposite, the combined chemical and thermal stresses induced reciprocal inactivation of the stress response, with antagonism effect on cortisol secretion, antioxidant defense induction and metabolic compensation. However, increased effect on behavioral traits and decreased global condition of fish were observed. Our study showed that temperature rising sensitized fish to pesticide exposure. Finally, inhibited stress response in fish exposed to pesticide cocktails raises concerns about species conservation an ecosystem under multiple pressures

Depuis 2006, la politique énergétique extérieure de l’Union européenne a été significativement renforcée. Cette politique très ambitieuse vise à assurer la sécurité des approvisionnements énergétiques dans l’Union et à contribuer à une utilisation plus durable de l’énergie à l’échelle universelle. Si le dialogue politique et les aides économiques sont essentiels à ces égards, l’Union fait principalement appel au droit pour libéraliser les marchés énergétiques des États tiers se trouvant à sa périphérie et pour diffuser sa vision de l’utilisation durable de l’énergie sur la scène internationale. Pour quelles raisons l’Union a-t-elle essentiellement recours au droit dans le cadre de cette politique ? S’agit-il d’un instrument efficace ? C’est à ces deux grandes questions que cette étude est consacréeSince 2006, the European Union’s external energy policy has been strengthening significantly. This ambitious EU policy is aimed at ensuring the security of energy supply in the EU and to contribute to more sustainable use of energy around the world. If political dialogue and economic aid are essential, the EU resorts principally to the law in order to liberalise energy markets of the third States in its periphery and to spread its vision of sustainable energy on the international stage. For which reasons does the EU use primarily the law in this policy? Is this instrument efficient? It is these two majors questions that this study addresses

Full textAbstract:
Transportations role in society is increasingly important and today it has a prominent role in business, citizens lives as well as in the world economy. The increasing globalization and urbanization puts significant pressure on the existing transport system, with increasing demand for high-speed travel. However, this comes with implications on the environment, and the environmental concerns constitutes one of the biggest pressures in transport. And as the contemporary modes are bound by their technologies, enabling marginal rather than radical improvements, a possible window of opportunity for new radical technologies to enter the market can emerge. One new technology emerging within transportation today is called hyperloop, a technology that could prove to meet demand for faster, cheaper, safer and more environmentally efficient transportation. However, the technology is still in an early stage of development and hence surrounded by major uncertainties. Further, the nature of the technology necessitates overcoming several obstacles before it can reach commercial practice. And this together with a limited knowledge of the concept in Sweden makes it difficult to predict if hyperloop can become a viable transport alternative on the Swedish market. Which condensed lays the foundation to the purpose of this paper: "To give an overarching understanding of the Swedish transport market dynamics, together with a comprehensive evaluation of the hyperloop concept. And hence contribute to more inclusive knowledge and understanding of hyperloop’s viability in the Swedish context." Since the phenomenon has not been comprehensively studied previously, the elected research design is that of an exploratory case study, with an inductive, qualitative approach. To address the purpose, a literary review of the theoretical field was conducted. Looking in to previous research on disruptive innovation, diffusion of innovations, technical transitions, transformational pressure as well as window of opportunity. The empirical material gathered during the research process was derived from two main channels. Firstly, an extensive review of scientific articles about the hyperloop technology was conducted, providing insights on the technology and its surroundings. This was complemented by qualitative interviews to obtain material on the dynamics of the Swedish transport market as well as for understanding hyperloop in the Swedish context. The empirical study was further accompanied by a review of news articles and websites to map the most recent progress in the hyperloop development. By analyzing the empirical material through three frameworks; Characteristics of Diffusion, the Multi-Level Perspective (MLP) and Technology Readiness Level (TRL), interesting findings and conclusions were drawn. These together points towards that hyperloop, if the technology reaches its predicted performance, will have significant relative advantages and observable effects in the relation to the contemporary modes of transportation. Further, a noticeable window of opportunity, sprung from capacity shortages and pressure towards environmental sustainability, seems to exist on the Swedish market. A window which could be capitalized upon and justify hyperloop in the Swedish context. The current state of the technology does however come with implications as it so far is insufficient to decrease uncertainty amongst the potential adopters. Factors that likely will prolong the adoption of the technology in Sweden relates to the relative complexity of the system, its limited compatibility with existing practices and the low maturity of the technology. Hence, the hyperloop companies must prove the concept feasible and increase the maturity to gain sufficient acceptance and recognition. This paper contributes to the academic community by assessing the compatibility of hyperloop on the Swedish market, as well as if hyperloop could become a viable alternative transport solution in Sweden. It provides insight to specific perspectives of the Swedish market, its requirements and the demand for alternative transport solutions. Hence, this paper is considered to make both an analytical contribution in terms of evaluating the viability of disruptive technologies. And an empirical contribution by shedding light on new important insights for the potential diffusion of hyperloop. Insights that are significant for hyperloop actors as well as for dominant actors on the Swedish transport market.Transporters roll i samhället blir allt viktigare och de har idag en framträdande roll inom näringsliv, medborgares liv samt världsekonomin. Den ökande globaliseringen och urbaniseringen sätter dock ett betydande tryck på det existerande transportsystemet, med ökande efterfrågan för höghastighetsalternativ. Detta medför implikationer för miljön, och oron kring transporters miljöpåverkan är ett av de största bekymren för transportsektorn. Eftersom de existerande transportalternativen är bundna av sin teknik, vilket begränsar dem till inkrementella snarare än radikala förbättringar, kan en möjlighet för nya transportsätt att komma in på marknaden öppna sig. En kommande ny teknik som utvecklas inom transport idag kallas hyperloop, en teknik som kan visa sig möta efterfrågan för snabbare, billigare, säkrare och mer miljösmarta transporter. Tekniken är dock i ett tidigt utvecklingsskede och är därav omgärdad av stora osäkerheter. Vidare kräver teknikens natur att flertalet hinder kommer att behöva överkommas innan tekniken kan nå kommersiellt bruk. Detta tillsammans med den begränsade kunskap som finns kring konceptet i Sverige gör det svårt att förutspå om hyperloop kan bli ett möjligt transportalternativ på den svenska marknaden. Kondenserat ligger detta till grund för syftet med den här uppsatsen: "Att ge en övergripande förståelse av dynamiken på den svenska transportmarknaden, tillsammans med en djupgående utvärdering av hyperloop konceptet. Och därav bidra till en mer inkluderande kunskap och förståelse kring hyperloops möjligheter i den svenska kontexten." Eftersom detta fenomen inte tidigare har studerats i större utsträckning valdes en forskningsdesign i form av en undersökande fallstudie med ett induktivt, kvalitativt tillvägagångssätt. För att adressera syftet gjordes en litterär översyn av det teoretiska fältet. Med inblickar i tidigare forskning kring disruptiv teknik, diffusion av innovation, tekniska övergångar, transformationstryck samt möjlighetsfönster. Det empiriska materialet till studien samlades in genom två kanaler i huvudsak. Först, genom en djupdykning i tidigare forskning och vetenskapliga artiklar relaterade till hyperlooptekniken, för att generera insikter kring tekniken och dess omgivning. Detta kompletteras med kvalitativa intervjuer för att erhålla material om dynamiken på den svenska transportmarknaden samt för att ge en förståelse av hyperloop i den svenska kontexten. Den empiriska studien kompletterades ytterligare med en översyn av nyhetsartiklar och webbplatser för att kartlägga de senaste framstegen i hyperlooputvecklingen. Genom att analysera det empiriska materialet med hjälp av tre ramverk; Egenskaper för Spridning av Innovation, Perspektiv i Multipla Nivåer (MLP) och Teknisk Mogenhetsnivå (TRL), kunde flertalet intressanta upptäckter och slutsatser dras. Vilka tillsammans pekar mot att hyperloop, om tekniken lyckas uppnå den predikterade prestandan, kommer att ha betydande relativa fördelar och synliga effekter i förhållande till dagens transportsätt. Vidare kan ett märkbart möjlighetsfönster, sprunget ur kapacitetsbrist och tryck mot miljömässig hållbarhet, identifieras på den svenska marknaden. Detta fönster skulle kunna kapitaliseras på och motivera hyperloop i den svenska kontexten. Teknologins nuvarande tillstånd har emellertid konsekvenser, eftersom den hittills inte är tillräcklig för att minska osäkerheten hos potentiella adopterare. Faktorer som sannolikt kommer att förlänga processen att adoptera tekniken i Sverige härstammar från systemets relativa komplexitet, dess begränsade kompatibilitet med befintliga metoder samt teknikens låga mogenhet. Därav är det essentiellt för hyperloopbolagen att bevisa konceptet möjligt och öka mogenheten för att få tillräcklig acceptans och erkännande. Detta arbete bidrar till det akademiska samhället genom att bedöma kompatibiliteten mellan hyperloop och den svenska marknaden, samt om hyperloop kan bli ett genomförbart transportalternativ i Sverige. Arbetet bidrar med insikter i specifika perspektiv på den svenska marknaden, dess krav samt efterfrågan för alternativa transportlösningar. Därav kan denna uppsats anses utgöra både ett analytiskt bidrag genom dess utvärdering av genomförbarheten av disruptiv teknik. Samt ett empiriskt bidrag genom att belysa viktiga insikter för den potentiella spridningen av hyperloop. Insikter som är viktiga för såväl hyperloopaktörer som de dominanta aktörerna på den svenska transportmarknaden.

Full textAbstract:
My professional interest as a business analyst influences this research into understanding
the successful adoption of change. Readiness for change is an essential aspect of
organisational change, with research consensus showing a positive correlation between
readiness for change and the effectiveness of organisational change. However, the
inability of many organisations to meet their desired change outcomes suggests we need
to know more about readiness for change.
Readiness for change describes members’ shared commitment to implement change and
their confidence in their capability to make the change. While readiness for change
involves social processes, in practice evaluation generally occurs at the individual level.
A multi-level understanding of readiness for change, including individual, group and
organisational levels, is still unclear.
Does readiness for change differ at the individual, group and organisational levels? Can
we interpret multi-level readiness for change from the individual’s readiness for change?
This thesis addresses these questions through a predominantly qualitative research design
combining a questionnaire based on established scales and individual interviews with
change practitioners.
This research is a phenomenological study as it explores the lived experiences of
individuals experiencing readiness for change to develop a greater understanding of
multi-level readiness for change. The convenience sampling method chosen incorporates
an aspect of multilevel sampling design combining people who have experienced a
workplace change and change professionals who have implemented a workplace change.
The findings of this research extend the literature on multilevel readiness for change. This
research also showed the need for organisations to develop their own readiness for change
framework to align with their culture. The high proportion of external change agents
interviewed provided the additional finding that external change agents are often
subjected to political influences undermining their change efforts and impacting their
ability to deliver effective and timely change outcomes.

Demand for non-volatile memory (NVM) has been increasing in the market. As the memory density continues to increase, scaling MOSFET transistor is a challenging task due to physical limitations. Phase change memory (PCM) has shown great potential among emerging non-volatile memory technologies due to its advantages of fast read-write ability, high scalability, good reliability and low power operation. In this paper, we develop a new compact memory model based on physical theory including temperature and crystalline calculation. We evaluate multi-level cell operation of phase change memory by using different programming techniques including proposed monotonically increasing and decreasing pulse, constant pulse and slow quenching schemes. We also compare the power consumption of the different logic level by using difference programming techniques. Our simulation results suggest that the proposed MLC schemes not only have an advantage in density but also consume less power during programming. Among the demonstrated programming techniques, our simulation results show that the increasing pulse technique is more power efficient than the other approaches.

Recording density of the erasable phase change optical disk is restricted to the optical diffraction limit. Multi-level recording has an advantage of increasing the recording density. A new multi-level phase change disk is composed of multi recording layers, which are in the same depth of focus of laser beam. By modulating the intensity of the laser pulse, marks can be chosen to be recorded in any of the recording layers, forming multi recording regions corresponding to different reflectance levels. Similarly, utilizing the modulation of laser power can directly overwrite the previous recording region to another one. For the four-level recording disk, four recording regions corresponding to four distinct reflectances can be produced. If each recording region represents two-bit, the effective mark length for one bit becomes only half of the actual mark length. Then, the recording density can be increased by the factor of two. In the thesis, the overwriting conditions have been demonstrated for three-level and four-level disk. At the laser wavelength of 660 nm and NA of 0.6, the resolvable smallest effect recording region which can be overwritten is 0.4μm. Meanwhile, the relation between the multi-level recording mechanism and multi-level readout signal has been analyzed. Due to the temperature difference of recording layers, mark can be chosen to form in any of recording layers to form multi recording regions. But the temperature difference of recording layers causes different mark sizes, which result in the distortion of readout signal. The improved mechanism is to adopt different recording material as recording layers. By utilizing the recording materials of different melting point of recording layers, the mark size in different recording layers can be controlled to enhance the signal quality. The CNR of the three-level disk with two recording layers of different composition ─AgInSbTe and GeSbTe is better than that of the three-level disk with two recording layers of the same composition material─GeSbTe.

Recording density of the erasable phase change optical disk is determined by the recorded mark size. When the mark size is smaller than the focus laser spot size which is limited by the optical diffraction limit, the readout signal is decreased simultaneously. Therefore, the smallest recorded mark size is limited by the optical diffraction limit which is about 0.6（λ/NA）, where λ and NA are the laser wavelength and the numerical aperture of the objective lens, respectively. In this thesis, ”Multi-level recording method” was proposed to increase recording density of optical disks without decreasing the recorded mark size. A new erasable multi-level recording phase change disk is composed of multi recording layers which are in the same depth of focus of laser beam. By modulating the intensity of the laser pulse, marks can be chosen to record in any of recording layers to form multi recording regions. Utilizing the property of the phase change media whose amorphous and crystalline states differ largely in refractive indices, each recording region corresponds to different reflectance. For the four-level recording disk, four recording regions corresponding to four distinct reflectances can be produced, and each recording region represents two-bit data. Thus the effective mark length for one bit becomes only one-half the actual mark length. As a result, the recording density can be increased without altering the current optic configuration of readout system. The multi-level readout signals of optical and thermal designed multi-level disks were examined experimentally. At the laser wavelength of 660nm and NA of 0.6, when the recorded effective mark size for one bit was about 0.3μm, the CNR（Carrier to Noise Ratio）of the four-level disk was above 36dB, much higher than that of the conventional disk of less than 25dB. Therefore, the resolvable smallest effective mark size was decreased, consequently disk capacity is greatly increased.

Full textAbstract:
Natural resources and rural livelihoods in Africa are under pressure due to climate change and ineffective management. It particularly affects countries where most of the population depends on natural resources for their livelihood, like Ethiopia. Even though, there is scientific and local knowledge on environmental management in the form of national strategies, stakeholders, and actions at multiple governance levels, it is lacking a proper interlinkage and public communication.
This research aims to contribute to narrow gaps between knowledge systems and enhance adaptive capacity by understanding barriers and drivers for knowledge generation and management in climate change adaptation. The study interlinks political ecology and social theoretical concepts for climate change adaptation and knowledge management in a multi-level governance framework representing one country. Ethiopia is focused on in this study because it is and will be greatly affected by climate change and has elaborated a national strategy to become a climate resilient middle-income country by 2025. The governance levels are analyzed with (1) determining the institutional framework, stakeholders, and networks at national level, (2) analyzing the structure, role and capacity of the extension system, (3) investigating local capacities and thresholds for access and participation in knowledge and governance processes for natural resource management. A focus is put on (4) area closures, as an example for an applied and common intervention of natural resource management in Ethiopia, which can serve as contribution to cope with climate change consequences. In a final step (5) interlinkages and compatibility of the governance levels in Ethiopia are evaluated to draw conclusions for a generalization of obstacles and potentials.
A two-level case study design was applied incorporating the national and local level of Ethiopia:Acknowledgements I
