Water Sensitive Urban Design (WSUD) as a climate adaptation strategy / Water Sensitive Urban Design (WSUD) som klimatanpassningsstrategi

Fumero, Andrea January 2020 (has links)
“Global floods and extreme rainfall events have surged by more than 50% in the past decade and recent studies show that they are occurring four times higher than in 1980” (Neslen, 2018). At the same time, the urban population is rising. Today, 55% of the world’s population lives in urban areas and it is estimated to increase to 70% by 2050 (United Nations, 2018). This expansion of urbanized areas is correlated with the increase of impermeable surfaces that, in case of extreme weather events, are not able to drain the water efficiently. The rainfall-runoff is channelled from roads, parking lots, buildings, and other impervious surfaces to storm drains and sewers that cannot handle the volume. The high ratio of impermeable surfaces and the increased extreme rainfall events cause severe environmental, social, economical problems in urban areas. Merely technical and engineering solutions are no sufficient, therefore a new approach that can maintain and adapt the natural water cycle inside the urban areas is needed. Ecosystem services and resilience thinking have become key principles in adaptation strategies at different levels, from international policies (e.g. Sustainable Development Goals) to local actions (e.g. Copenhagen adaptation plan 2015) and design (e.g. climate resilient San Kjeld in Copenhagen). In this scenario, the design approach of Water Sensitive Urban Design (WSUD) aims to promote resilience at the local level by managing stormwater, encouraging the defence of the aesthetic value of green and blue areas. WSUD is a multidisciplinary approach that involves water management, urban planning, architecture, and landscape design. The main idea of WSUD is that sustainable stormwater systems should be beautiful, meaningful, and educational (Echols, 2007). This master thesis explores the concept of Water Sensitive Urban Design and its application in the cities of Copenhagen, Malmö and Rotterdam. The case study of PHVision in Heidelberg, Germany, is analysed from the concept of WSUD. Design improvements are suggested stemming from the analysed European examples and the theoretical background.

EU i en osäker värld : En kvalitativ idéanalys av hur Rysslands invasion av Ukraina har påverkat fokuset i EU:s försvars- och säkerhetspolitik / The EU in an insecure world : A qualitative analysis of how the Russian invasion of Ukraine effected the ideas underpinning EU's defence- and security politics

Gustafsson, Fanny January 2024 (has links)
The Russian invasion of Ukraine marked the end of a period of peace on the Europeancontinent and as it constituted a significant shift in the geopolitical environment thisevent likely influenced the actions and worldview of important actors in the region suchas the EU. The aim of this essay is thus to examine to what extent the Russian invasionof Ukraine caused a shift in EU’s defence- and security politics as well as their view oninternational relations. In an attempt to answer this question a qualitative analysis oftwo of the Unions strategic documents, the EU Global Strategy from 2016 and theStrategic Compass from 2022, was conducted. By utilizing ideal types of the theoriesliberal internationalism, realism, social constructivism and the Copenhagen School’swidened security agenda the analysis found that there has been a shift in the ideasunderpinning EU’s security politics from liberal internationalism towards more realismand that the military and economic sector had been successfully securitized. In otherwords, the EU's defence- and security politics shifted after the Russian invasion ofUkraine towards a bigger focus on military capabilities and towards a view of the worldas a more threatening and competitive place.

Building Social Sustainability from the Ground Up: The Contested Social Dimension of Sustainability in Neighborhood-Scale Urban Regeneration in Portland, Copenhagen, and Nagoya

Kohon, Jacklyn Nicole 28 May 2015 (has links)
In response to growing social inequality, environmental crises, and economic instability, sustainability discourse has become the dominant "master signifier" for many fields, particularly the field of urban planning. However, in practice many sustainability methods overemphasize technological and economic growth-oriented solutions while underemphasizing the social dimension. The social dimension of sustainability remains a "concept in chaos" drawing little agreement on definitions, domains, and indicators for addressing the social challenges of urban life. In contrast, while the field of public health, with its emphasis on social justice principles, has made significant strides in framing and developing interventions to target the social determinants of health (SDH), this work has yet to be integrated into sustainability practice as a tool for framing the social dimension. Meanwhile, as municipalities move forward with these lopsided efforts at approaching sustainability practice, cities continue to experience gentrification, increasing homelessness, health disparities, and many other concerns related to social inequity, environmental injustice, and marginalization. This research involves multi-site, comparative case studies of neighborhood-scale sustainability planning projects in Portland, U.S.; Copenhagen, Denmark; and Nagoya, Japan to bring to light an understanding of how the social dimension is conceptualized and translated to practice in different contexts, as well as the challenges planners, citizen participants, and other stakeholders encounter in attempting to do so. These case studies find that these neighborhood-scale planning efforts are essentially framing the social dimension in terms of principles of SDH. Significant challenges encountered at the neighborhood-scale relate to political economic context and trade-offs between ideals of social sustainability, such as social inclusion and nurturing a sense of belonging when confronted with diverse neighborhood actors, such as sexually oriented businesses and recent immigrants. This research contributes to urban social sustainability literature and sustainability planning practice by interrogating these contested notions and beginning to create a pathway for integration of SDH principles into conceptualizations of social sustainability.

Validating results from the Molten Salt Reactor Experiment by use of turbulent CFD simulations : A study of a modified U-tube shell-and-tube primary heat exchanger and radiator with molten salts

Akner, Malcolm January 2021 (has links)
Background Nuclear reactors utilizing molten fuels rather than solid fuels show a massive advantage in energy yield, waste handling and safety features. The only successful reactor utilizing a molten fuel was called the ‘Molten Salt Reactor Experiment’ (MSRE), built and operated in the Oak Ridge national laboratory (ORNL) in Tennessee, U.S.A. during the 1960s. The molten salts in question are fluoride compounds under the name of “FLiBe”. In this thesis, the heat exchangers of the MSRE are modelled and simulated, with the aim to test whether current computational fluid dynamics (CFD) software and mathematical models can accurately predict molten salt heat transfer behaviour.  Methods All programs used are open-source and/or free-access to facilitate open collaboration between researchers in this growing field. All models and findings produced in this thesis are free to use for future research. The program Onshape was used to draw CAD-models based on hand-drawn technical documents released by ORNL. Several programs, e.g., Simscale and Salome, were used to create high detailed meshes of the heat exchangers. The CFD software Simscale and OpenFOAM have been used to simulate the heat exchangers, using the 𝑘 − 𝜔 𝑆𝑆𝑇 Reynolds averaged Navier-Stokes (RANS) turbulence model to perform a multiregion conjugate heat transfer (CHT) analysis. The program Paraview has been used for all post-processing on the large datasets.  Results A working toolchain with open-source programs for CFD has been identified. Highly detailed, full-scale and accurate CAD-drawings of the two heat exchangers have been produced. Models have been finely meshed, containing tens of millions of cells, with good quality measures. The simulations produced physically sound and valuable data: Great heat transfer predictive capability with high accuracy to the data presented by ORNL. Pressure data showed a consistent over-prediction with a factor of ~2. Possibility of error within the MSRE measurement.  Conclusions CHT using modern turbulence methods work well for the intended purpose and can be used by industry to simulate molten salt heat transfer. Open-source programs perform well and can be used by researchers to share ideas and progress. Doubts around certain measurements from the MSRE, showing large uncertainties. Future projects have been outlined to continue the work performed in this thesis. Molten salt reactors show fantastic promise as an energy generation method and should be seriously considered for the future of clean, reliable energy.

Syndrom vyhoření - diagnostické možnosti (srovnávací studie) / Burnout syndrome - diagnostic possibilities (comparative study)

Vlachovská, Barbora January 2011 (has links)
The theoretical part deals with key issues of burnout - a definition, phase of syndrome, diagnostic classification, prevention, and mainly deals with the description of the methods by which the level of burnout is detected. Now probably the most common diagnostic tools are the MBI (Maslach Burnout Inventory) and its derivatives (eg. MBI-General Survey), but there are many other methods, such as developed by Israeli and European psychologists (BoTeLis, OLBI, CBI, MBS, etc.). The goal is to assemble a relatively complete overview of these diagnostic tools.In the empirical part, is to verify the psychometric properties of Czech version of the selected methods on a set of population, describe and analyze their characteristics.

Syndrom vyhoření u vysokoškolských pedagogů - mezinárodní srovnávací studie / Burnout Syndrome in University Teachers - International Comparative Study

Černíková, Barbora January 2014 (has links)
This thesis is concerned with the phenomenon of burnout in university teachers, who have been previously rather neglected in connection with this topic. The theoretical part provides an analysis of current knowledge regarding the development of the concept of burnout from the very early interest in this issue in the 1970s to the present, with emphasis being placed on the teaching profession, especially in the tertiary education sector. In the empirical part of the research, the assumption of different levels of burnout in university teachers in the former Eastern Bloc and Western European country was tested. This international study compares the burnout level in teachers from the philosophy faculties of Czech Charles University and German Universität Regensburg. In order to achieve a more holistic view of this topic, the levels of life engagement and depression have been studied as well. The data were collected with the help of Copenhagen Burnout Inventory, Life Engagement Test, Beck Depression Inventory and a sociodemographic questionnaire. Basic research assumption predicting differences in levels of burnout, life engagement and depression in Czech and German university teachers was confirmed in only one burnout subscale, namely the subscale of student-related burnout. Additionally, the...

EU, Serbien och det första Köpenhamnskriteriet : En kvalitativ fallstudie om implementerandet av det första Köpenhamnskriteriet i Serbien / EU, Serbia and the first Copenhagen criteria : A qualitative case study on the implementation of the first Copenhagen criteria in Serbia

Karlsson, Mikaela January 2018 (has links)
Serbia is said to enter the European Union (EU) in 2025 and a criteria for inclusion in the EU are the Copenhagen criteria’s. The purpose of this thesis is to examine how the EU as an external and international actor acts to further the implementation of the first Copenhagen criteria concerning democratic institutions, the rule of law, human rights and protection of minorities. Through a qualitative theory consuming study this thesis investigates the EUs aims and actions in Serbia, a country outside the boards of the EU by applying a theoretical framework based on Lawrence Whiteheads theory on international dimensions of democratization. As a result the thesis finds that the European Union has an interest in democracy promotion in Serbia as defined in the Copenhagen criteria. The EU uses several different methods such as economic aid, learning resources, diplomacy and normative contagion to attain its purpose. But the true reason behind the EUs interest is Serbia is discussed among scholars as well as the effective ways of implementing EUs strategies and the development of sanctions against states that do not comply with the democratic values of the Copenhagen criteria.

L’entrée de la Hongrie dans l’Union Européenne. Enjeu - processus d’adhésion et intégration sur le plan politique et social : la question rom au centre du débat / Hungary’s entry in the European Union Stakes, adhesion process and integration on a political and social basis : the Roma question at the center of the debate

Berki, Gabriella 25 June 2010 (has links)
La Hongrie est membre de l’Union Européenne depuis le premier mai 2004. Après les premières élections libres du printemps 1990, les gouvernements successifs ont entamé et mené à bien les préparatifs d’adhésion en se conformant aux critères de Copenhague de 1993. Le propos de cette thèse est d’examiner les transformations politiques, économiques et sociales sur une longue période [1990-2009] afin de mettre en évidence la complexité des relations entre l’intégration européenne et une démocratie moins stable qu’on ne le pensait, d’autant que la question rom révèle non seulement la persistance, mais encore la prospérité d’idées nationalistes et racistes. / Hungary has been a member of the European Union since May 1st, 2004. After the first free elections in spring 1990, governments began and achieved the entry process to the European Union following the 1993 Copenhagen criteria. This thesis aims to examine the political, economical and social transformations in the scope of a long era [from 1990 to 2009] in order to show the complexity of the relations pertaining to the European integration and a less stable democracy than one thought, especially since the Roma question reveals not only persisting but also flourishing nationalistic and racist ideologies.

[en] SECURITIZATION AND (IN)SECURITY PRACTICES IN EUROPE: THE CASE OF FRONTEX / [pt] SECURITIZAÇÃO E PRÁTICAS DE (IN)SEGURANÇA NA EUROPA: O CASO DA FRONTEX

DANIEL EDLER DUARTE 21 August 2013 (has links)
[pt] A dissertação analisa de forma crítica parte da literatura de segurança internacional que advoga pela ampliação da agenda do campo, evidenciando as consequências éticas e políticas de se adotar a lógica da securitização em análises sobre questões sociais. Para tanto, são abordadas as contribuições da Escola de Copenhague às análises sobre a política de controle de fronteiras da União Europeia (UE). Este estudo tem como linha condutora as diferentes visões sobre a criação da Frontex, agência que, apesar das acusações de desrespeito aos direitos dos imigrantes, tornou-se a principal produtora de conhecimento acerca dos riscos às fronteiras europeias. Por fim, é abordada a contribuição do campo da Sociologia Política Internacional para os estudos de segurança, especialmente os trabalhos de Didier Bigo e Jef Huysmans. Esta perspectiva realça os principais problemas da ampliação da agenda de segurança e seu impacto no Estado liberal, demonstrando que há uma modificação drástica nas formas de governança, com restrições à liberdade individual em prol de um suposto aumento de proteção. Deste modo, o objeto desta dissertação é tanto a literatura da Escola de Copenhague, compreendendo suas limitações práticas e silêncios políticos, quanto a própria Frontex, cujas operações são evidências empíricas dos argumentos de Bigo e Huysmans. / [en] This dissertation criticizes part of the literature on international security that advocates for the expansion of the agenda of the field, evidencing the ethical and political consequences of adopting the securitisation perspective while analysing social issues. In this sense, the theoretical contributions of the Copenhagen School to the interpretations of the European Union (EU) policy of boarder control are addressed. This work has as its conductive line the different visions on the creation of the Frontex, an agency that, depite being accused of disrespecting the rights of immigrants, became the main producer of knowledge on the risks to European boarders. Finally, the contribution of the International Political Sociology field to security studies is addressed, mainly through the work of Didier Bigo and Jef Huysmans. This perspective highlights the main problems of widening the security agenda and its impact in the Liberal State, demonstrating that there is a drastic change in the forms of governance, with restrictions to individual freedoms on behalf of an alleged increase in protection. Thereby, the object of this dissertation is both the Copenhagen School literature, understanding its practical limitations and political silences, and Frontex itself, whose operations are empirical evidences of Bigos and Hyusmans s arguments.

The Euro-Mediterranean Partnership: Critical Assessment of the Security Aspects

Toplu, Esra January 2004 (has links)
<p>This thesis attempts to assess the security aspect of the Barcelona Process (Process), or so called Euro-Mediterranean Partnership (EMP) within the theoretical framework of new regionalism and the Copenhagen School (Security complex theory) which agrees with neo/realism, neo-liberal institutionalism and constructivism in some aspects. The end of the Cold War broadened the security agenda and new security concerns emerged. Actually, most of the so- called security threats are not new, but the perception of them by the states has changed with globalization which increased the interconnectedness and density of the interaction. Global challenges have made states more vulnerable so appreciated the cooperative interaction at regional level. Comprehensive and cooperative security approaches gained importance and led regional security partnership among states. The construction of Euro-Mediterranean security partnership is one case stemming from the high level of interdependence between the European and the Mediterranean countries. The historical ties, economic dependency, geographical proximity increased the EU’s interest towards the Mediterranean. While new regionalism enables to grasp systemic factors in the Process, the Copenhagen School permits to understand security partnership at the regional level. The rise of illegal immigration flows and religious fundamentalism in the Mediterranean as well as tension in the Middle East conflict, the Iraqi War, and terrorist attacks to the US, Algeria and recently Turkey appreciated the importance of the EMP policy and security cooperation so make this study more crucial. </p><p>This study showed that the security challenges in five sectors of the security defined by the Copenhagen School are observable in the EMP’s case. Both military and non-military concerns threaten the stability and prosperity in the Mediterranean Basin. The three baskets of the EMP depict its comprehensive security approach. Having made an overview of the Barcelona Process, the thesis evaluated the security challenges in general and the thematic areas of concerns in depth. Since security cannot be defined without reference to the perceptions and security cultures of the actors, the study examined the perceptions and security cultures in the EMP. </p><p>The evaluation of the EMP showed that the EMP has shown certain developments on the way for the security cooperation. However, it could not produce tangible results due to the fundamental shortcomings categorized as inter and intra-institutional incoherence, definitional/perceptional problems and multi- actor involvement in the region. The lack of institutional structures, asymmetrical relations among partners, unbalanced distribution of powers and lack of commitment of the EU are crucial problems. On the basis of all problems lie the gap between the perceptions and security culture of Europe and the Arab world. Thus, this thesis emphasizes the enhancement of inter- subjective understanding and cultural dialogue in order to improve trust and interaction among partners. The EMP is on right track to build zone of peace in the Basin, but it requires longue durée to achieve this.</p>
