This thesis is about some recent developments on Geometric Analysis and Geometric Measure Theory on RCD(K,N) metric measure spaces that have been obtained in [8,48,49,51,52,171].
After the preliminary Chapter 1, where we collect the basic notions of the theory relevant for our purposes, Chapter 2 is dedicated to the presentation
of a simplified approach to the structure theory of RCD(K,N) spaces via δ- splitting maps developed in collaboration with Brué and Pasqualetto. The strategy is similar to the one adopted by Cheeger-Colding in the theory of Ricci limit spaces and it is suitable for adaptations to codimension one.
Chapter 3 is devoted to the proof of the constancy of the dimension conjecture for RCD(K,N) spaces. This has been obtained in a joint work with
Brué, where we proved that dimension of the tangent space is the same almost everywhere with respect to the reference measure, generalizing a
previous result obtained by Colding-Naber for Ricci limits. The strategy is
based on the study of regularity of flows of Sobolev vector fields on spaces
with Ricci curvature bounded from below, which we find of independent
interest.
In Chapters 4 and 5 we present the structure theory for boundaries of sets
of finite perimeter in this framework, as developed in collaboration with
Ambrosio, Brué and Pasqualetto. An almost complete generalization of
De Giorgi’s celebrated theorem is given, opening to further developments
for Geometric Measure Theory in the setting of synthetic lower bounds on
Ricci curvature.
In Chapter 6 we eventually collect some results about sharp lower bounds
on the first Dirichlet eigenvalue of the p-Laplacian based on a joint work
with Mondino. We also address the problems of rigidity and almost rigidity,
heavily relying on the compactness and stability properties of RCD spaces.

Le but principal de ce manuscrit est celui de présenter une nouvelle méthode d'interpolation entre des probabilités inspirée du problème de Schrödinger, problème de minimisation entropique ayant des liens très forts avec le transport optimal. À l'aide de solutions au problème de Schrödinger, nous obtenons un schéma d'approximation robuste jusqu'au deuxième ordre et différent de Brenier-McCann qui permet d'établir la formule de dérivation du deuxième ordre le long des géodésiques Wasserstein dans le cadre de espaces RCD* de dimension finie. Cette formule était inconnue même dans le cadre des espaces d'Alexandrov et nous en donnerons quelques applications. La démonstration utilise un ensemble remarquable de nouvelles propriétés pour les solutions au problème de Schrödinger dynamique :- une borne uniforme des densités le long des interpolations entropiques ;- la lipschitzianité uniforme des potentiels de Schrödinger ;- un contrôle L2 uniforme des accélérations. Ces outils sont indispensables pour explorer les informations géométriques encodées par les interpolations entropiques. Les techniques utilisées peuvent aussi être employées pour montrer que la solution visqueuse de l'équation d'Hamilton-Jacobi peut être récupérée à travers une méthode de « vanishing viscosity », comme dans le cas lisse.Dans tout le manuscrit, plusieurs remarques sur l'interprétation physique du problème de Schrödinger seront mises en lumière. Cela pourra aider le lecteur à mieux comprendre les motivations probabilistes et physiques du problème, ainsi qu'à les connecter avec la nature analytique et géométrique de la dissertationMain aim of this manuscript is to present a new interpolation technique for probability measures, which is strongly inspired by the Schrödinger problem, an entropy minimization problem deeply related to optimal transport. By means of the solutions to the Schrödinger problem, we build an efficient approximation scheme, robust up to the second order and different from Brenier-McCann's classical one. Such scheme allows us to prove the second order differentiation formula along geodesics in finite-dimensional RCD* spaces. This formula is new even in the context of Alexandrov spaces and we provide some applications.The proof relies on new, even in the smooth setting, estimates concerning entropic interpolations which we believe are interesting on their own. In particular we obtain:- equiboundedness of the densities along the entropic interpolations,- equi-Lipschitz continuity of the Schrödinger potentials,- a uniform weighted L2 control of the Hessian of such potentials. These tools are very useful in the investigation of the geometric information encoded in entropic interpolations. The techniques used in this work can be also used to show that the viscous solution of the Hamilton-Jacobi equation can be obtained via a vanishing viscosity method, in accordance with the smooth case. Throughout the whole manuscript, several remarks on the physical interpretation of the Schrödinger problem are pointed out. Hopefully, this will allow the reader to better understand the physical and probabilistic motivations of the problem as well as to connect them with the analytical and geometric nature of the dissertation

This thesis is devoted to the study of structural properties of non-smooth spaces with Ricci curvature bounded from below.
The first part concerns with the structure theory of RCD(K,N) spaces: we prove the existence of the so-called essential dimension, along with rectifiability properties of the regular set. This theory is a result of many contributions [43,72,91,95,109,121], in our presentation we closely follow the recent works [41,43].
The second part of this thesis deals with codimension-1 structures on RCD(K,N) spaces. More precisely we study structural properties of boundaries of sets with finite perimeter, generalising the celebrated De Giorgi theory [65, 66] to this framework. This is based on the works [7,40].

In this Thesis, we analyze three variational and geometric problems, that extend classical Euclidean issues of the calculus of variations to more general classes of spaces. The results we outline are based on the articles [Ved21; MV21] and on a forthcoming joint work with Nicolussi Golo and Serra Cassano. In the first place, in Chapter 1 we provide a general introduction to metric measure spaces and some of their properties. In Chapter 2 we extend the classical Talenti’s comparison theorem for elliptic equations to the setting of RCD(K,N) spaces: in addition the the generalization of Talenti’s inequality, we will prove that the result is rigid, in the sense that equality forces the space to have a symmetric structure, and stable. Chapter 3 is devoted to the study of the Bernstein problem for intrinsic graphs in the first Heisenberg group H^1: we will show that under mild assumptions on the regularity any stationary and stable solution to the minimal surface equation needs to be intrinsically affine. Finally, in Chapter 4 we study the dimension and structure of the singular set for p-harmonic maps taking values in a Riemannian manifold.

The effects of spatial structure are explored using a simple model of migration between two populations, each in a balance between mutation and stabilising selection on an additive polygenic trait. Gene flow can maintain genetic variance within each population, albeit at low levels. If the optimum fluctuates in time, much higher levels of genetic variation can be maintained within populations, and in the presence of isolation divergence between the populations can be seen. Biotic interactions may be an important factor maintaining variation within and between populations, and these may lead to Red Queen dynamics even in constant environments. Here I define the Red Queen very broadly as "ongoing coevolution", and discuss the use of the terms 'coevolution' and 'ongoing'. I suggest that different Red Queen type processes can be classified the amount of novelty available in the system and by whether or not increasing sophistication occurs. In this thesis I model a specific biotic interaction: the coevolution of parasites with the acquired immunity of their hosts. High levels of linkage disequilibrium (strain structure) can be maintained in this system, and for a large range of parameters Red Queen type dynamics are observed. In some cases fluctuations in linkage disequilibrium and epistasis may result in a fairly large advantage to sexual over asexual recombination. However, this advantage is not large enough to outweigh the "two-fold cost of sex". This deterministic advantage arises primarily because recombination impedes the response to fluctuating epistasis rather than because it facilitates the response to directional selection. Sex may also be advantageous in the presence of Red Queen type dynamics because sexual genotypes that are stochastically lost can be recreated through recombination, unlike their asexual counterparts.

Fluid flow in porous media is important for a number of fields including nuclear waste disposal, oil and gas, fuel cells, water treatment and civil engineering. The aim of this work is to improve the current understanding of how the pore space governs the fluid flow in porous media in the context of nuclear waste disposal. The effects of biofilm formation on flow are also investigated. The thesis begins with a review of the current porous media characterisation techniques and the means for converting the pore space into pore network models and their existing applications. Further, I review the current understanding of biofilm lifecycle in the context of porous media and its interactions with fluid flow. The model porous media used in this project is Hollington sandstone. The pore space of the material is characterised by X-ray CT and the equivalent pore networks from two popular pore network extraction algorithms are compared comprehensively. The results indicate that different pore network extraction algorithms could interpret the same pore space rather differently. Despite these differences, the single-phase flow properties of the extracted networks are in good agreement with the estimates from a direct approach. However, it is recommended that any flow or transport study using pore network modelling should entail a sensitivity study aiming to determine if the model results are extraction method specific. Following these results, a pore merging algorithm is introduced aimed to improve the over segmentation of long throats and hence improve the quality of the extracted statistics. The improved model is used to study quantitatively the pore space evolution of shale rock during pyrolysis. Next, the extracted statistics from one of the algorithms is used to explore the potential of regular pore network models for up-scaling the flow properties of porous materials. Analysis showed that the anisotropic flow properties observed in the irregular models are due to the different number of red (critical) features present along the flow direction. This observation is used to construct large regular models that can mimic that behaviour and to discuss the potential of estimating the flow properties of porous media based on their isotropic and anisotropic properties. Finally, a long-term flow-through column experiment is conducted aiming to understand the effects of bacterial colonisation on flow in Hollington sandstone. The results show that such systems are quite complex and are susceptible to perturbations. The flow properties of the sandstone were reduced significantly during the course of the experiment. The possible mechanisms responsible for the observed reductions in permeability are discussed and the need for developing new imaging techniques that can allow examining biofilm development in-situ is underlined as necessary for drawing more definitive conclusions.

We present the observations, reduction and preliminary analysis of a sample of 45 mid-to-high redshift galaxy clusters imaged with the Spitzer Space Telescope's MIPS camera at 24 ~m and selected from the Red Sequence Cluster Survey. The purpose of the data set is motivated by a broad review of studies into the evolutionary trends of galaxy clusters and their constituent galaxy populations, focusing specifically on recent results that indicate clusters are environmental drivers of dusty starburst and active galactic nuclei activity. To accommodate the large amount of data in hand, we have constructed an extensive data reduction pipeline for the MIPS data and describe its development and output in detail. Using the resulting catalogues for introductory analysis, we find strong evidence for an excess luminous infrared galaxy population in galaxy clusters at high redshift and discuss the implications of this discovery in terms of cluster evolution and motivate future work.

La Red de Alamedas de Bogota is a new type of public space project consisting in a network of tree lined pedestrian streets with bicycle paths. Alamedas connect parks and natural systems as well as residential areas and urban facilities. In general, .£!,Iamedas have been proposed for the periphery of the city where there is a lack of public space. La red de Alamedas was developed during the administration of Enrique Perialosa, Bogota City Mayorfrom 1998 to 2000; improvement of the quantity and quality of public space was one of Penalosa's government plan priorities. Moreover, a new general plan for the city, Plan de Ordenamiento Territorial, POT was developed during those years. Thus, alamedas became public space projects in more comprehensive interventions in the city. Alamedas proceed from a range of concerns in the construction of the city such as the development of public space projects to overcome the difficulties of general plans when dealing with particular problems and specific areas, and as a way to improve the quality of life in the city. Besides, alamedas can be considered a reinterpretation of promenades and paseos, an urban type which has been present in the city since colonial times. Alamedas have been proposed as a new public space which is superimposed to the existing urban structure in certain areas in order to reorganize the urban structure and at the same time as a new way of building the city that is, through the construction of public space in the first place. Most the alamedas are still urban design projects, only two of the alamedas included in this document have been built. Alamedas have different characters according to the areas and the urban conditions of the proposed corridors. Alameda EI Porvenir, the most ambitious one has been studied in more depth. Alamedas work as an alternative path for pedestrian and bicycle circulation and are at the same time a recreational space; besides, alamedas have also started to become a representative space much in the way of the traditional plaza.

This study investigates the social construction of race, marine space, and resource conflict in one U.S. Native American community: the Makah Reservation, Neah Bay, Washington. A combination of archival records, news media coverage, and semistructured interviews is employed in order to expose the historic roots of the Makah Tribe's recent movement to reclaim control over traditional marine spaces. In particular, this research focuses on the gray whale controversy period between 1995-2000, when, to the consternation of conservation non-governmental organizations (NGOs), Makahs organized to resume a limited, cultural based harvest of the California gray whale in Pacific waters. This paper suggests that extant conflicts which developed between the Makah people, on one hand, and anti-whaling NGOs on another, were as much a struggle over marine space as they were a struggle over gray whale resources. Three central conclusions are drawn from the study. First, it is shown that Pacific marine "space" serves as a distinct, historical territory upon which many of the Makahs' political, cultural, and economic processes take form. Second, this research argues that NGO efforts to arrest the Makahs' contemporary whale harvest in offshore Pacific waters have been interpreted by tribal members as a neocolonialist invasion into what was once customarily managed marine space. Third, these results show how, despite the dominance of anti-whaling NGOs, Makahs have effectively mobilized global media technologies in order to empower themselves politically, transcend the territorial boundaries of the reservation, and reclaim control over the marine environment.

In the middle of the California Desert is an inland desert sea, called the Salton Sea. Its existence is curious, nearly magical. It is California’s largest lake, it is saltier than the Pacific Ocean, it is slowly dying, and its existence is a complete accident. This thesis breaks down the historical narrative of the Salton Sea from a white settler perspective, using theories posed by Yi Fu Tuan about distinctions between space and place. The temporality of spatial locations, the construction of the binaries natural/built, and the moralizing of landscapes all provide further understanding of the Salton Sea’s existence. Throughout history, the white settlers of the Imperial Desert have projected, their morals and desires upon the desert landscape, reforming the space into their vision of the future as a result of their abilities to tame and control rivers. Instead of a future, they produced a place replete with the past: a place considered worthless and potentially dangerous. Through looking at the constructions of space, place, memory, and history, we are better able to understand the birth of this desert sea.

Children around the world suffer greatly due to conflicts. One of the most common interventions to support children affected by conflicts are Child Friendly Spaces (CFSs). Implemented within different cultural contexts, CFSs aim to be both culturally sensitive and contribute to gender equality, an interaction that can be complex. Previous research regarding CFSs is limited. As CFSs are commonly used in Humanitarian Action, further knowledge is central.This thesis aims to explore and compare how culture and gender appropriate responses in CFSs guidelines and manuals are expressed in order to gain an increased understanding of how these guidelines handle the interaction between gender norms in different cultures.In this study I discuss six CFSs guidelines and manuals by conducting comparative analysis and applying the Ecological Resilience Framework.The result suggests that culture and gender appropriate responses are central in all guidelines and manuals but emphasized in different ways. The participation of children, families and communities, as well as the adaption of activities, are all strategies aimed at cultural sensitivity. The result also entails that the equal inclusion of all children is a general gender appropriate approach. In addition, I claim that the main intervention, aiming to be both gender and culture appropriate, is separated groups between boys and girls. Finally, I argue that gender and culture may clash due to different perceptions of gender and culture appropriate responses.

O presente trabalho tem por objetivo compreender a formação do MUR (Ministério Universidade Renovadas) - um movimento estudantil ligado à RCC (Renovação Carismática Católica) - em suas estratégias de inserção empreendidas pelos mesmos nas universidades. Posteriormente, busca-se abordar as implicações e/ou aplicações dos ideais compartilhados pelos membros do MUR na vida profissional dos indivíduos que dele fizeram parte e que depois de formados integram os GPPs (Grupo de Partilha Profissional). Tal estudo propõe avaliar os desdobramentos da influência religiosa desses estudantes em sua ação pública e investigar o diálogo entre a subjetividade e esferas mais amplas de constituição da identidade desses jovens que, transitando entre um ambiente de suposta efervescência científica (a universidade) e outro que favorece a experimentação mística/emocional (a Renovação Carismática Católica) negociam valores ideológicos supostamente antagônicos: razão/fé/ethos juvenil.

"Authenticity, Citizenship and Accommodation: LGBT Rights in a Red State" examines the discourse around volunteerism, exceptionalism, and queer citizenship that emerged within the context of a statewide (anti-gay) ballot initiative campaign in the American Southwest. I argue that the ways in which local volunteers and activists define themselves and their attempts to defeat the ballot initiative is tied to the struggle over the authority to represent local LGBT organizational culture and an emergent New West identity. In such a way, local debates over authentic western lifestyles that divide regional communities intertwine with intergenerational debates over gay liberation and rights frameworks, and the polarized discourse on blue and red states which have dominated the U.S. political climate of the past decade. While statewide campaign leaders with a base in Phoenix (the state capital) focused on polling data and messaging in order to stop the passage of the amendment, many Tucson activists and organizational leaders tied to the LGBT community center sought to strategize a long-term grassroots approach to change hearts and minds. Within this debate over campaign strategy and internal decision-making, both groups drew attention to the differences between the metropolitan areas. This regional example speaks to the ways in which established theoretical frameworks anthropologists utilize to understand social movements may prove insufficient for understanding the diversity that exists within the everyday processes of collective action. The internal messaging war that spilled outside of the confines of the campaign steering committee meetings into the pages of the statewide gossip and newspaper editorial sections also speaks to the ways in which official declarations of ideological stance should not be taken as the actual intent of those seeking change. One may shape one's personal story to be on message, choose to defy those constraints, or use the rhetorical strategy of the message without actually committing to the underlying premise. The broader national concerns are localized symbolically in the notion of blue and red counties, but also take on a regional flavor in the satirical call to statehood for the Southern Arizona. Here issues of authenticity emerge not only within the context of the campaign disputes around messaging, and by extension, who has the right to speak for and about the LGBT organizational community, but also in the realm of derisive banter that travels back and forth between the two major metropolitan areas over what it means to live an authentic western lifestyle. Within the southern metropolis, this discourse is framed by the notion that the western desert is a different sort of place, with a different sort of people and way of life that is threatened by snowbirds, retirees, Midwestern lifestyles and corporate interests. Often Phoenix to the north is seen as a representation of all these negative influences. In addition, Center-based activists and volunteers, describe their southern city in idealistic terms as an oasis for LGBT community, artists, activists, migrants, refugees, and all manner of progressive politics. Memory enacted through the telling of one's story at a Coming Out Day testimonial, political rallies and in dialogue with an anthropologist are shaped by these notions of difference. These notions of difference also emerge as a pattern in the narrative construction of space, violence and memory within activist life histories. These life histories in turn reveal a fragment of local LGBT organizational culture, in which the process of professionalization transforms the meaning of community, and the act of representation transforms the role of activist into that of the citizen volunteer. The community center in this sense is a memorialization of community and movement culture, and by idealizing what came before it masks material conditions at the same time that it offers up the potential of a more radical present/future. While the community center, Tucson and Pima County are coded as oases of safety, this image is continually disrupted by counter narratives, including the state-wide campaign to stop the marriage amendment; local support for the Protect Marriage and anti-immigrant amendments; and evidence of on-going violence directed against racial, ethnic and religious minorities and those who transgress hetero and gender normative expectations. These disruptions however appear to be cyclical in that they allow both professionals and concerned community members (citizen volunteers) to rally together in a show of strength and solidarity and in so doing represent the authentic, legitimate community. However, these disruptions may also allow for counter narratives to enter into public discourse, thereby offering up a more radical envisioning of community beyond the limits of LGBT organizational culture.

Point processes are common in many physical applications found in engineering and biology.
These processes can be observed in one-dimension as a time series or two-dimensions as a spatial point pattern with extensive amounts of literature devoted to their analyses.
However, if the observed process is a hybrid of spatial and temporal point process, very few practical methods exist.
In such cases, practitioners often remove the temporal component and analyze the spatial dependencies.
This marginal spatial analysis may lead to misleading results if time is an important factor in the process.
In this dissertation we extend the current analysis of spatial point patterns to include a temporal dimension.
First- and second-order intensity measures for analyzing spatiotemporal point patterns are explicitly defined.
Estimation of first-order intensities are examined using 3-dimensional smoothing techniques.
Conditions for weak stationarity are provided so that subsequent second-order analysis can be conducted.
We consider second-order analysis of spatiotemporal point patterns first in the space-time domain through an extension of Ripley's $K$-function.
An alternative analysis is given in the frequency domain though construction of a spatiotemporal periodogram.
The methodology provided is tested through simulation of spatiotemporal point patterns and by analysis of a real data set.
The biological application concerns the estimation of the homerange of groups of the endangered red-cockaded woodpecker in the Fort Bragg area of North Carolina.
Monthly or bimonthly point patterns of the bird distribution are analyzed and integrated over a 23 month period.Ph. D.

State-space modelling is a powerful tool to study ecological systems. The direct inclusion of uncertainty, unification of models and data, and ability to model unobserved, hidden states increases our knowledge about the environment and provides new ecological insights. I extend the state-space framework to create multi-species models, showing that the ability to model ecosystem interactions is limited only by data availability. State-space models are fit using both Bayesian and Frequentist methods, making them independent of a statistical school of thought. Bayesian approaches can have the advantage in their ability to account for missing data and fit hierarchical structures and models with many parameters to limited data; often the case in ecological studies. I have taken a Bayesian model fitting approach in this thesis. The predator-prey interactions between the hen harrier (Circus cyaneus) and red grouse (Lagopus lagopus scoticus) are used to demonstrate state-space modelling’s capabilities. The harrier data are believed to be known without error, while missing data make the cyclic dynamics of the grouse harder to model. The grouse-harrier interactions are modelled in a multi-species state-space model, rather than including one species as a covariate in the other’s model. Finally, models are included for the harriers’ alternate prey. The single- and multi-species state-space models for the predator-prey interactions provide insight into the species’ management. The models investigate aspects of the species’ behaviour, from the mechanisms behind grouse cycles to what motivates harrier immigration. The inferences drawn from these models are applicable to management, suggesting actions to halt grouse cycles or mitigate the grouse-harrier conflict. Overall, the multi-species models suggest that two popular ideas for grouse-harrier management, diversionary feeding and habitat manipulation to reduce alternate prey densities, will not have the desired effect, and in the case of reducing prey densities, may even increase the harriers’ impact on grouse chicks.

Power converters used in high reliability radiation hardened space applications trail their commercial counterparts in terms of power density and efficiency. This is due to the additional challenges that arise in the design of space rated power converters from the harsh environment they need to operate in, to the limited availability of space qualified components and field demonstrated power converter topologies. New radiation hardened Gallium Nitride (GaN) Field Effect Transistors (FETs) with their inherent radiation tolerance and superior performance over Silicon Power Metal Oxide Semiconductor Field Effect Transistors (MOSFETs) are a promising alternative to improve power density and performance in space power converters.
This thesis presents the considerations and design of a practical implementation of the Phase Shifted Full Bridge DC-DC Isolated converter with synchronous rectification for space applications. Recently released radiation hardened GaN FETs were used in the Full Bridge and synchronous rectifier power stages. A survey outlining the benefits of new radiation hardened GaN FETs for space power applications compared to current radiation hardened power MOSFETs is included. In addition, this work presents the overall design process followed to design the DC-DC converter power stage, as well as a comprehensive power loss analysis.
Furthermore, this work includes details to implement a conventional hard-switched Full Bridge DC-DC converter for this application. An efficiency and component stress comparison was performed between the hard-switched Full Bridge design and the Phase Shifted Full Bridge DC-DC converter design. This comparison highlights the benefits of phase shift modulation (PSM) and zero voltage switching (ZVS) for GaN FET applications. Furthermore, different magnetic designs were characterized and compared for efficiency in both converters. The DC-DC converters implemented in this work regulate the output to a nominal 20 V, delivering 500 W from a nominal 100 V DC Bus input. Complete fault analysis and protection circuitry required for a space-qualified implementation is not addressed by this work.MS

“Area restriction” is the umbrella term used for this thesis to consider geography-based, individually- assigned orders issued by criminal justice agents to remove and restrict targets from particular city spaces. This research focuses on 13 Canadian cities that use arrest-and-release area restriction strategies to managing street sex work(ers). Despite heavy criticism for their punitive nature, area restrictions have received little academic attention. This project takes an exploratory and descriptive approach to the issue in order to develop a platform for future research. Using qualitative, non-experimental methods it also critically analyzes the implementation, logic and reported impacts of the strategies while drawing implications for how area restrictions relate to citizenship statuses of sex workers by mapping exclusions onto the city. Multiple data sources were included but the most significant and compelling information comes from interviews with police officers and community agency workers. Findings suggest that area restriction strategies contribute to substantial social divides between sex workers and other community members, but also between sex workers and important services, resources and their community. At the same time, the strategy is reported as a “temporary relief” measure that is ineffective at lessening sex trade activity and often leads to displacement and dispersal of sex work(ers). However, collaborative efforts in some cities show promise for achieving goals of ‘helping sex workers off the street.’ Realistic recommendations for area restriction strategies are made that lead to more inclusive approaches that are considerate of needs and concerns of all interest groups linked to the “prostitution problem.”

It is 150 years since the establishment of the International Committee of the Red Cross (ICRC), following Henry Dunant’s experiences during the aftermath of the Battle of Solferino. It is 100 years since the commencement of the Great War: if we think about a ‘traditional’ battlefield, what images come to mind? Perhaps one imagines soldiers in uniform, tanks, guns and trenches. Do the emblems of the International Red Cross and Red Crescent Movement (IRCRCM) feature in the imagined conflict scenario? Now imagine the conflicts happening today in, for example, Syria, Mali, Democratic Republic of Congo (DRC) and Ukraine. In these conflicts, soldiers mingle with civilians in towns, armoured vehicles and open backed trucks transport non- uniformed soldiers between conflict areas and weapons include, amongst others, improvised explosive devices, suicide bombers and sexual violence. Nevertheless the emblems of the IRCRCM continue to emblazon the uniforms of medical personnel and their equipment, vehicles and aid boxes. What consequences do the changes in the nature of armed conflicts have for the ICRC? The human consequences of conflict and the presence of the ICRC has been a constant for 150 years, but the needs of the population and the types of violence continually change. Indeed, since the creation of the ICRC in 1863, the methods, means and actors in conflicts have changed, but so has the practice of the ICRC. This thesis considers the legality of such developments. The ICRC is, perhaps most significantly, the self-entitled, ‘guardian’ of international humanitarian law (IHL) and a neutral and independent entity. This thesis considers the activities currently undertaken by the ICRC in the name of ‘humanitarianism’. It addresses whether a strict interpretation of the Geneva Conventions I, II, III and IV 1949, Additional Protocols I and II and Statutes of the ICRC would show that it is, as an organisation, usurping its mandate and principles. It also takes into account the ‘ICRC Study on Customary IHL’. The thesis examines the issue of whether the ICRC is an organisation with International Legal Personality (ILP) and, if so, whether it has legitimately extended its role beyond that provided in the Geneva Conventions I, II, III and IV 1949, Additional Protocols I and II and the Statutes of the IRCRCM. More broadly therefore the thesis examines the relationship between the ICRC and international law, including IHL, jus ad bellum and international human rights law (IHRL). One unique contribution made by this thesis is to undertake a substantial analysis of the meaning and implementation of humanity, which is a principle of the IRCRCM. The IRCRCM definition of the principle of humanity is: The International Red Cross and Red Crescent Movement, born of a desire to bring assistance without discrimination to the wounded on the battlefield, endeavours, in its international and national capacity, to prevent and alleviate human suffering wherever it may be found. Its purpose is to protect human life and health and to ensure respect for the human being. It promotes mutual understanding, friendship, cooperation and lasting peace amongst all people. Chapter five of the thesis shows that emerging concepts in the latter part of the twentieth century, in particular sovereignty as responsibility, human security and the Responsibility to Protect (RtoP), are indicative of a development within the international community which identified the plight of individuals within sovereign States as relevant to the international community at large. In particular, the ‘humanity’ and humanitarian needs of people living within states, in particular during and after conflict, became part of international discourse. Humanitarian assistance is no longer restricted to the provision of aid to soldiers. The idea of inhumanity in internal armed conflicts also gained traction on the international stage. It is evident from recent conflicts such as Libya, Syria and Ukraine that international willingness and ability to respond to such situations varies considerably. This thesis, therefore, considers whether the ICRC is able to reach people on the ground in a way that more politicised actors, such as the UN, are not. It considers whether there is a case to be made for a humanitarian approach to protection during, and after, armed conflict? Is the ICRC capable of reaching individuals and communities in a promising and effective way? Has the ICRC had to adapt its humanitarian assistance and protection roles to adequately respond to the changing nature of armed conflicts? These questions permeate the analysis of the mandate of the ICRC and its current work, which is undertaken throughout this thesis. Critically, this thesis dedicates a chapter to analyse what ‘humanity’ means today. In much literature humanity is considered in terms of IHL, which, it is argued, provides a limited definition of such. Likewise, much literature on the ICRC centre’s on its links to IHL. The ICRC often forms a subsection of a chapter on IHL or is viewed through the lens of IHL. This thesis goes further than traditional accounts of the ICRC, as it presents the ICRC as key actor in the long-term protection and assistance of individuals and communities suffering through and trying to recover from armed conflict. It addresses the question of how to interpret ‘humanity’ and whether, perhaps, there is a case to argue that it can and should be interpreted more broadly, given the influx of human focused concepts to emerge since the end of the Second World War. This thesis focuses on sovereignty as responsibility, human security and Responsibility to Protect (RtoP) as key examples of such, as they all relate to humanitarianism. Their specific links are considered in detail in chapter five. Teitel published ‘Humanity’s Law’ in 2011 which reflects on issues similar to those contained in this thesis. However, much of Teitel’s analysis remains grounded in ‘black-letter’ law, whereas this thesis is taking a socio-legal approach and focuses on the law and practice of the ICRC. Humanity’s Law, as a concept, is very close to this Author’s interpretation and understanding of international law and the international legal order, and, as such, it is imperative to refer, throughout the thesis, to ideas put forward in ‘Humanity’s Law’. In terms of existing literature and academic argument on the matter of ‘humanity’, Teitel provides a comprehensive analysis of case law and theory. In addition much literature on the ICRC dedicates a passing comment to the Principles of the IRCRCM, which include ‘humanity’. Sovereignty as responsibility, human security and RtoP are reflective of a shift away from a state-centric model of the international legal order. There is increasing awareness and political will in terms of the plight of vulnerable populations in need. The key for this thesis is whether the ICRC mandate and practice are reflective of the developing notions of humanity, that is, is the ICRC ‘buying in’ to security or interventionist interpretations of humanity? Or, which would be a much more daring conclusion to draw, is the ICRC actually ‘feeding’ the development of ‘humanity’ as a concept which is, in turn, permeating international legal discourse more broadly? The traditional theory of human security, as proposed by the United Nations Development Programme in 1994, considered economic, food, health, environmental, personal, community and political security to be of consequence to the people living in conflict and other insecure environments. These types of security were seldom prioritised in traditional security paradigms, which focused on national security. This thesis considers human security to be of continuing importance to people on the ground during and after armed conflict and other situations of violence. For people trying to rebuild their lives, family life, food, health and community security are as important, if not more important, than the maintenance of territorial borders. In this regard, it considers the work of the Economic Security (EcoSec) Unit, which assesses needs at household level in order to obtain first-hand local information. This thesis required the undertaking of interviews with ICRC delegates at the headquarters in Geneva. The literature in this area is somewhat limited and that which is produced comes predominantly from the ICRC. It was necessary therefore to undertake empirical research to provide an original contribution to research in this field and to comprehensively address the research questions of this thesis. Finally, this thesis uses a case study of the ongoing conflict in the DRC to examine the activities of the ICRC and shows how, and to what extent, the changes within the ICRC practice are impacting people on the ground. The case study was also informed by the interviews.

ABSTRACT
COMPARATIVE SEQUENCE ANALYSIS OF THE INTERNAL TRANSCRIBED SPACER 2 REGION OF TURKISH RED PINE (Pinus brutia TEN.) AND NATURAL ALEPPO PINE (Pinus halepensis MILL.) POPULATIONS FROM TURKEY
Tozkar, Özge M.S., Department of Biology Supervisor: Prof. Dr. Zeki Kaya April, 2007, 107 pages Turkish red pine (Pinus brutia) is wide-spread and an important forest tree species in Turkey, occurring mainly in southern, western and north-western Turkey and as small isolated populations in the Black Sea region. Aleppo pine (Pinus halepensis) has naturally found only in Adana and Mugla provinces as small population in mixture with Turkish red pine. Although Turkish red pine and Aleppo pine are morphologically different, Turkish red pine has been regarded as subspecies of Aleppo pine by some taxonomists due to occurrence of natural hybridization between these two species. However, the phylogenic relationship between these species needs to be explored further. In the present study, by sampling overlapped populations of both species from Mugla and Adana provinces (4 populations of Turkish red pine and 3 populations of Aleppo pine), internal transcribed spacer (ITS) region of ribosomal DNA were comparatively studied with sequence analysis. Although ITS1, 5.8s and ITS2 regions of ribosomal DNA were studied with ITS primers, only ITS2 region was successfully amplified with polymerase chain reaction (PCR). The complete data set for this region was analysed using MEGA3.1 and Arlequin softwares. Analysis of molecular variance (AMOVA) demonstrated the highest genetic differentiation between Turkish red pine and Aleppo pine in Mugla with 100 percentage of variation. AMOVA analysis also indicated the possibility of low-level migration of genes between Turkish red pine and Aleppo pine populations in Adana with 50.65 percent of molecular variance. Haplotype comparison revealed that two major haplotypes were represented Based on the results of ITS2 region sequence analysis, Turkish populations of Aleppo pine and Turkish red pine populations could not be fully differentiated. In Mugla province Turkish red pine and Aleppo pine revealed more differentiation due to reproductive isolation. But in Adana province, two species shared more common genetic background due to possible hybridization. Since ITS2 region of nuclear ribosomal DNA revealed a few variable and parsimony informative sites for both species, thus, only ITS2 region of ribosomal DNA does not appear to be sufficient for fully resolving genetic relationships between Turkish red pine and Aleppo pine populations. Further studies including ITS1 and 5.8s regions of ribosomal DNA and populations included from major Aleppo pine distribution areas will be useful to understand the evolutionary relationship between Aleppo pine and Turkish red pine populations in Turkey.

Complex networks are mathematical representations of the interaction patterns of complex systems. During the last 20 years of Network Science, it has been recognized that networks from utterly different domains exhibit certain universal properties. In particular, real complex networks present heterogeneous, and usually scale-free, degree distributions, a large amount of triangles, or high clustering coefficient, a very short diameter, and a clear community structure. Among the vast set of models proposed to explain the structure of real networks, geometric models have proven to be particularly promising.
This thesis is developed in the framework of hidden metric spaces, in which the high level of clustering observed in real networks emerges from underlying geometric spaces encoding the similarity between nodes. Besides providing an intuitive explanation to the observed clustering coefficient, geometric models succeed at reproducing the structure of complex networks with high accuracy. Furthermore, they can be used to obtain embeddings of networks, that is, maps of real systems enabling their geometric analysis and efficient navigation.
This work introduces the main concepts in the hidden metric spaces approach and presents a thorough description of the main models and embedding procedures. We generalize these models to generate networks with soft communities, that is, with correlated positions of nodes in the underlying metric space. We also explore one of the models in higher similarity-space dimensions, and show that the maximum clustering coefficient attainable decreases with the dimension, which allows us to conclude that real-world networks must have low-dimensional similarity spaces as a consequence of their high clustering coefficient.
The thesis also includes a detailed geometric analysis of the international trade system. After reconstructing a yearly sequence of world trade networks covering 14 decades, we embed them into hyperbolic space to obtain a series of maps, which we named The World Trade Atlas 1870-2013. In these maps, the likelihood for two countries to be connected by a significant trade channel depends on the distance among them in the underlying space, which encodes the different factors influencing trade interactions. Our analysis of the networks and their maps reveals that the world is being shaped by three different forces acting simultaneously: globalization, localization and hierarchization.
The hidden metric spaces approach can be exploited beyond network metrics. We show that similarity space defines a notion of scale in real-world networks. We present a Geometric Renormalization Group transformation that unveils a previously unknown self-similarity of real networks. Remarkably, the phenomenon is explained by the congruency of real systems with our model. This renormalization transformation provides us with two immediate applications: a method to construct high-fidelity smaller-scale replicas of real networks and a multiscale navigation protocol in hyperbolic space that outperforms single-scale versions.
The geometric origin of real networks is not restricted to their binary structure, but it affects their weighted organization as well. We provide empirical evidence for this claim and propose a geometric model with the capability to reproduce the weighted features of real systems from many different domains. We also present a method to infer the level of coupling of real networks with the underlying metric space, which is generally found to be high in real systems.Les xarxes complexes representen els patrons d’interacció dels sistemes complexos. S’ha observat repetidament que xarxes d’àmbits molt diferents comparteixen certes propietats, com l’heterogeneïtat del nombre de veïns o el clustering elevat (alta presència de triangles), entre d’altres. Tot i que s’han proposat molts models per explicar aquesta universalitat, els models geomètrics han demostrat ser particularment prometedors. Aquesta tesi es desenvolupa en el context dels espais mètrics ocults, en el qual la natura del clustering s’explica geomètricament en termes de similitud entre nodes. Els models basats en aquesta assumpció no només poden reproduir l’estructura de les xarxes reals amb molta precisió, sinó que permeten obtenir mapes de xarxes reals. En aquest treball, introduïm els conceptes bàsics dels espais mètrics ocults, els seus models principals i els mètodes d’obtenció de mapes. També generalitzem aquests models al règim amb correlacions geomètriques entre nodes, i explorem la qüestió de la dimensió de l’espai de similitud. La nostra anàlisi ens permet concloure que l’espai de similitud de les xarxes reals ha de tenir dimensionalitat baixa. Incloem una anàlisi geomètrica detallada de l’evolució del sistema de comerç internacional basada en els mapes a l’espai hiperbòlic de les xarxes corresponents, al llarg de 14 dècades. En aquests mapes, la proximitat entre pa¨ısos representa la probabilitat d’interaccionar comercialment. L’anàlisi mostra que el món evoluciona d’acord amb tres forces que actuen simultàniament: la globalització, la localització i la jerarquització. Els espais de similitud defineixen una noció d’escala en xarxes reals. Proposem una transformació de renormalització que revela una auto-similitud de sistemes reals anteriorment desconeguda. A més, proposem dues aplicacions d’aquesta transformació: un mètode per a obtenir versions reduïdes de xarxes reals i un mètode multiescalar per a navegar-les. Finalment, mostrem que les estructures pesades dels sistemes reals també tenen un origen geomètric i proposem un model capaç de reproduir-les amb precisió. Desenvolupem un mètode per a inferir el nivell d’acoblament de les xarxes reals amb els espais mètrics subjacents i trobem que aquest és generalment elevat.

By studying how captive animals use outdoor space, we can determine which areas fulfill their biological and behavioral needs to improve enclosure design for animal welfare and visitor experience. The aim of the study was to determine the differential use of outdoor space in a mixed exhibit of captive ring-tailed lemurs (Lemur catta) and red ruffed lemurs (Varecia rubra), and to assess both the effect of adding environmental enrichment and possible visitor and meteorological effects on the lemurs’ use of space and behavior. For one month, five-minute interval scan sampling was used to record lemur location and behavior, as well as the meteorological conditions and presence of zoo visitors in the lemurs’ outdoor enclosure. That baseline was followed by four alternating two-week periods of food or structural enrichment, both with and without visitors. Enrichment increased the lemurs’ use of the enriched sectors, decreased resting, and increased locomotion. Structural enrichment increased their exploratory behaviors and stimulated arboreal locomotion. Both species preferred sunny and warm conditions for sunbathing and resting, while moving more around the enclosure in cooler and cloudier weather. The visitor effect on the lemurs’ use of space was weaker than the effects of enrichment and meteorological conditions. The availability of areas to hide and possible habituation to humans may have played a role in the reduced visitor effect. The results of the study showed inter-specific differences in the lemurs’ use of space and behavior and a complex combined effect of enrichment, visitor presence and meteorological conditions.

Semantic segmentation of a scene aims to give meaning to the scene by dividing it into meaningful — semantic — parts. Understanding the scene is of great interest for all kinds of autonomous systems, but manual annotation is simply too time consuming, which is why there is a need for an alternative approach. This thesis investigates the possibility of automatically segmenting 3D-models of urban scenes, such as buildings, into a predetermined set of labels. The approach was to first acquire ground truth data by manually annotating five 3D-models of different urban scenes. The next step was to extract features from the 3D-models and evaluate which ones constitutes a suitable feature space. Finally, three supervised learners were implemented and evaluated: k-Nearest Neighbour (KNN), Support Vector Machine (SVM) and Random Classification Forest (RCF). The classifications were done point-wise, classifying each 3D-point in the dense point cloud belonging to the model being classified. The result showed that the best suitable feature space is not necessarily the one containing all features. The KNN classifier got the highest average accuracy overall models — classifying 42.5% of the 3D points correct. The RCF classifier managed to classify 66.7% points correct in one of the models, but had worse performance for the rest of the models and thus resulting in a lower average accuracy compared to KNN. In general, KNN, SVM, and RCF seemed to have different benefits and drawbacks. KNN is simple and intuitive but by far the slowest classifier when dealing with a large set of training data. SVM and RCF are both fast but difficult to tune as there are more parameters to adjust. Whether the reason for obtaining the relatively low highest accuracy was due to the lack of ground truth training data, unbalanced validation models, or the capacity of the learners, was never investigated due to a limited time span. However, this ought to be investigated in future studies.

Based upon the export product space, this paper shows the main features of the export product composition of Peru and its regions. With respect to export baskets, these include: a high con- centration in few commodities; a relatively low degree of similarity between products; relatively high levels of productivity at the international level, and; enormous undiscovered or untapped export potential. In addition, this paper analyzes the hypothesis that the natural resource curse affects regional growth, employment and export diversification. Subject to the limitations of the data and the heterogeneous panel methods employed, estimation results indicate that the share of natural capital out of the total tangible wealth and natural capital per capita seems, on average and in a relatively statistically robust way, to spur growth, primary employment and export concentration in a few products. Consequently, the natural resource curse for the Peruvian regions is not about growth but about low regional development, since such resources do not have a significant impact on secondary and tertiary employment or on export product diversification.Basado en la red de espacio de productos de exportación, este trabajo muestra las principales características de la composición de productos de exportación del Perú y sus regiones. Entre ellas: la de ser altamente concentrada en pocos productos intensivos en el uso de recursos naturales (RN), muy distantes unos de otros, de altos niveles de productividad internacional relativos al valor agregado real per cápita de cada región y de la economía en general, y de un enorme potencial de exportación todavía no explotado o descubierto. De otro lado, se analiza la validez de la hipótesis de la maldición de los efectos de los RN sobre el crecimiento y complementariamente sobre el empleo y la diversificación de los productos de exportación a nivel regional. Sujeto a las limitacio- nes de la información y métodos de paneles heterogéneos empleados, la evidencia relativamente robusta estadísticamente indica que la participación del capital natural del total de riqueza tangible y el capital natural per cápita han incidido en promedio positivamente en el crecimiento regional, el empleo relativo del sector primario, y la concentración de los principales productos de exportación. En consecuencia, la ‘maldición’ radica en la dependencia de las regiones en los RN para crecer retardando así el desarrollo regional por los efectos no significativos sobre elempleo secundario y terciario, y el proceso de diversificación de exportaciones.

Para o geógrafo da religião, os estudos têm por análise a dimensão espacial da fé, no tempo e no espaço, trata-se da análise de duas categorias: o sagrado e o profano. Esta pesquisa visa como objetivo, o estudo da comunidade católica, a Canção Nova, inserida em um movimento renovador na Igreja Católica Apostólica Romana denominada Renovação Carismática Católica (RCC) em seu espaço e no tempo de fé. Torna-se necessário desenvolver a importância do sagrado no Vale do Paraíba Paulista em seus sucessivos (re) arranjos espaciais na hierópolis de Cachoeira Paulista. A interpretação dessas organizações espaciais ocorreu ao analisar os possíveis agentes modeladores no espaço: peregrinos, turistas, visitantes, comerciantes e moradores. O Espaço Sagrado e seus respectivos espaços vinculados representaram a contribuição geográfica dessa dissertação e facilitou a compreensão do homem com o divino e sua relação na dimensão econômica, a dimensão política e a dimensão do lugar.
The geography of religion in Brazil after 1990 has been presenting themes that assist geographers in the understanding of space. The geographer of religion studies by analyzing the spatial dimension of faith, in time and space. It is the analysis of two categories: the sacred and the profane. This researchs objective is the study of the catholic community, New Song, set in a renewal movement in the Roman Catholic Church called the Catholic Charismatic Renewal (CCR) in its space and time of faith. It is necessary to develop the importance of the sacred in the Vale do Paraiba Paulista at its subsequent (re) spatial arrangements in Hierópolis of Cachoeira Paulista. The interpretation of these organizations is to analyze the spatial potential modeling agents in space: pilgrims, tourists, visitors, merchants and residents. The Sacred Space and their respective spaces linked, geographically, represented the contribution of this dissertation and facilitated the understanding of man with the divine and its relation in the economic dimension, the political dimension and the dimension of the place.

The project focuses on the design of a sustainable urban structure in the southeastern part of an area called Červený kopec, in the land of former brick factory. This urban-planning study endeavors to create a suitable structure for the brick factory brownfield. There are relevant factors which influence the proposal, such as complicated terrain due to the mining history, inconsistency of the surrounding urban structure, improper traffic accessibility, and orientation towards the city centre. The concept is based on the legacy of the area. It builds on the slopes and steep hills and preserves two building of the old factory, which aims to become the centre of the whole area. It is also important to mention the nearby National Landscape Heritage Červený Kopec, which would be connected via a forest-park to the recreational area of Mahenova stráň. The outline of this park creates a soft partition between the city and the park. The whole area is accessible by traffic from three access points, one of which is a newly constructed crossroad with traffic lights connected to the street Jihlavská. This proposal emphasizes the effectivity of the land use, traffic hierarchy, human scale, and the importance of pedestrian movement. The area is characterized by central design, with the ethos of the brick factory. It creates a cultural centre for the whole district and sets the way for new development or restructuralization towards a sustainable future for the city of Brno.

This research has as an empirical universe, the productive territory of red ware in the Serid? region of Rio Grande do Norte. In the last years this territory has gone through a process of appropriation that has been substantially changing the environmental and social dynamism of the place. However, the industry of red ware has been focusing in some areas, mainly, in the county of Parelhas and Carna?ba dos Dantas. From this point of view, the aim of this work consists in analyze the use of these areas by the red ware industry and the transformations occurred with the expansion of the number of industries and the productivity raise, that requires bigger amounts of earthenware and wood, resources that are low in referred territory. As the result of this process, the suitable alternative has been to acquire inputs in other Rio Grande do Norte counties, as well as in Para?ba counties. To reach the proposed objective, the methodology of this work was consisted of bibliographic and empirical research, regarding the occupation that this activity covers in the Serid? region. From the information obtained during the research, it can be stated that the inputs to the production execution in the red ware industry are acquired in the geographic nearby lands. The analysis of the stages of the production(acquisition of raw material, production and commercialization) showed that the activity acts in a continuous area, having as principal consumer market other northeastern states and the state of Par?. The present study revealed that the pottery activity is set as untenable, because of non-stopping use of the argil and wood, resources that are vanishing from the area, which consume causes a many problems such as deforestation and erosion. Besides, the sale of productive lands for the red ware industries makes harder its good use by the familiar agriculturists in the development of agriculture and cattle raising activity, which for many times is the main economic activity of the place. The precariousness reveals in the constant accidents at work, that most of them are neglected by the local authorities, without any penalty to the industries. Therefore, the industry of red ware in Serid? uses the territory as a resource, leaving its environmental problems that my compromise the quality of life of the actual and future generations
Esta pesquisa tem como universo emp?rico, o territ?rio produtor de cer?mica vermelha no Serid? potiguar. Nos ?ltimos anos esse territ?rio passou por um processo de apropria??o que tem alterado substancialmente a din?mica social e ambiental do lugar. No Serid?, a ind?stria de cer?mica vermelha tem se concentrado em algumas ?reas, sobretudo, nos munic?pios de Parelhas e Carna?ba dos Dantas. Nesta perspectiva, o objetivo desse trabalho consiste em analisar o uso do territ?rio pela ind?stria de cer?mica vermelha e as transforma??es ocorridas com a expans?o no n?mero de ind?strias e no aumento da produtividade, o que requer maiores quantidades de argila e de lenha, recursos escassos no referido territ?rio. Em decorr?ncia desse processo, a alternativa encontrada tem sido adquirir os insumos em outros munic?pios do Rio Grande do Norte, como tamb?m em munic?pios paraibanos. Para alcan?ar o objetivo proposto, o encaminhamento metodol?gico envolveu pesquisa bibliogr?fica e emp?rica, considerando a espacializa??o que essa atividade abrange no territ?rio seridoense. A partir das informa??es obtidas durante a pesquisa pode-se afirmar que os insumos para a realiza??o da produ??o na ind?stria de cer?mica vermelha s?o adquiridos no seu entorno geogr?fico. A an?lise das etapas do circuito de produ??o (aquisi??o da mat?ria-prima, produ??o e comercializa??o) mostrou que esta atividade atua numa ?rea cont?nua, tendo como principal mercado consumidor os demais estados do Nordeste e o estado do Par?. O presente estudo revelou ainda que a atividade ceramista configura-se como insustent?vel, haja vista a recorr?ncia permanente ? argila e ? lenha, insumos escassos no territ?rio, cuja aquisi??o provoca uma s?rie de problemas como o desmatamento e a eros?o. Al?m disso, a venda dos solos f?rteis para as cer?micas dificulta o seu aproveitamento pelos agricultores familiares, no desenvolvimento das atividades agropecu?rias, que muitas vezes configura-se na principal atividade econ?mica da propriedade. A precariedade da atividade se revela nos constantes acidentes de trabalho, que na grande maioria, s?o negligenciados pelas autoridades locais, sem aplica??o de nenhuma penalidade ?s empresas. Assim, a ind?stria de cer?mica vermelha no Serid? usa o territ?rio de forma seletiva e excludente, deixando s?rias problem?ticas ambientais, as quais podem comprometer a qualidade de vida das atuais e futuras gera??es

Les challenges posés par les missions d’exploration du système solaire sont très différents de ceux de la Station Spatiale Internationale, puisque les distances sont beaucoup plus importantes, limitant la possibilité de ravitaillements réguliers. Les systèmes support-vie basés sur des plantes supérieures et des micro-organismes, comme le projet de l’Agence Spatiale Européenne (ESA) MELiSSA (Micro Ecological Life Support System Alternative) permettront aux équipages d’être autonomes en termes de production de nourriture, revitalisation de l’air et de recyclage d’eau, tout en fermant les cycles de l’eau, de l’oxygène, de l’azote et du carbone, pendant les missions longue durée, et deviendront donc essentiels.La croissance et le développement des plantes et autres organismes biologiques sont fortement influencés par les conditions environnementales (par exemple la gravité, la pression, la température, l’humidité relative, les pressions partielles en O2 et CO2). Pour prédire la croissance des plantes dans ces conditions non-standard, il est crucial de développer des modèles de croissance mécanistiques, permettant une étude multi-échelle des différents phénomènes, ainsi que d’acquérir une compréhension approfondie de tous les processus impliqués dans le développement des plantes en environnement de gravité réduite et d’identifier les lacunes de connaissance.En particulier, les échanges gazeux à la surface de la feuille sont altérés en gravité réduite, ce qui pourrait diminuer la croissance des plantes dans l’espace. Ainsi, nous avons étudié les relations complexes entre convection forcée, niveau de gravité et production de biomasse et avons trouvé que l’inclusion de la gravité comme paramètre dans les modèles d’échanges gazeux des plantes nécessite une description précise des transferts de matière et d’énergie dans la couche limite. Nous avons ajouté un bilan d’énergie au bilan de masse du modèle de croissance de plante déjà existant et cela a ajouté des variations temporelles sur la température de surface des feuilles.Cette variable peut être mesurée à l’aide de caméras infra-rouges et nous avons réalisé une expérience en vol parabolique et cela nous a permis de valider des modèles de transferts gazeux locaux en 0g et 2g, sans ventilation.Enfin, le transport de sève, la croissance racinaire et la sénescence des feuilles doivent être étudiés en conditions de gravité réduite. Cela permettrait de lier notre modèle d’échanges gazeux à la morphologie des plantes et aux allocations de ressources dans une plante et ainsi arriver à un modèle mécanistique complet de la croissance des plantes en environnement de gravité réduiteChallenges triggered by human space exploration of the solar system are different from those of the International Space Station because distances and time frames are of a different scale, preventing frequent resupplies. Bioregenerative life-support systems based on higher plants and microorganisms, such as the ESA Micro-Ecological Life Support System Alternative (MELiSSA) project will enable crews to be autonomous in food production, air revitalization, and water recycling, while closing cycles for water, oxygen, nitrogen, and carbon, during long-duration missions and will thus become necessary.The growth and development of higher plants and other biological organisms are strongly influenced by environmental conditions (e.g. gravity, pressure, temperature, relative humidity, partial pressure of O2 or CO2). To predict plant growth in these non-standard conditions, it is crucial to develop mechanistic models of plant growth, enabling multi-scale study of different phenomena, as well as gaining thorough understanding on all processes involved in plant development in low gravity environment and identifying knowledge gaps.Especially gas exchanges at the leaf surface are altered in reduced gravity, which could reduce plant growth in space. Thus, we studied the intricate relationships between forced convection, gravity levels and biomass production and found that the inclusion of gravity as a parameter in plant gas exchanges models requires accurate mass and heat transfer descriptions in the boundary layer. We introduced an energy coupling to the already existing mass balance model of plant growth and this introduced time-dependent variations of the leaf surface temperature.This variable can be measured using infra-red cameras and we implemented a parabolic flight experiment, which enabled us to validate local gas transfer models in 0g and 2g without ventilation.Finally, sap transport needs to be studied in reduced gravity environments, along with root absorption and leaf senescence. This would enable to link our gas exchanges model to plant morphology and resources allocations, and achieve a complete mechanistic model of plant growth in low gravity environments

Previous issue date: 2011-12-16The alcohol sector has shown a remarkable process of expansion since 2000, towards the central Cerrado, admittedly favored by situation anchored in renewable energy and defense of national sovereignty. The state of Goias is one of the prime targets of this expansion, since 2004, primarily from 2006 to 2007, and has been concentrating a strong sugar industry in southern Goiás / Southwest Microregion of Quirinópolis (MRQ), where he spent about 4 000 ha more than 150 000 ha planted in the period, with great impact on the local socio-economy, according to previous studies, and subsidiaries of this thesis. This micro-region has favorable soil and climatic characteristics and economic importance of high logistics intra-and inter-regional exports, but the changes in land use and environmental impacts related to this process are still poorly studied. This thesis aims to understand the spatial pattern of expansion of sugarcane and the MRQ, with emphasis on soil and its use changes, considered by many authors as the agricultural frontier expansion of the 1970s, but more organized and capitalized technified, aiming prove the hypothesis that there has been setting a new centrality of the sugarcane industry in the Cerrado, focusing on production of ethanol and bio-energy, multi-scale consequences of which affect, among other things, the other pre-existing supply chains, especially food production. We analyzed in more detail the succession of land uses in the period since 2004, before the arrival of the cane in order to identify the substitution patterns of crops and pastures by the new culture and the potential for direct environmental impacts of sugarcane due observation of pressure on water resources for irrigation purposes and on soils associated with the management system of high technological standards, involving inputs and pesticides, and heavy machinery, among others. The research was based mainly on compiling data and maps, and thematic development of multi-scale cartographic documents, including use of satellite imagery and GIS analysis of census data and detailed study of various impacts on soil and water resources, with sampling Field and laboratory analysis. It is concluded that sugarcane has focused initially on the best land of the MRQ, where it has the best infrastructure in regional / state, where it stood, triumphant, with other uses, in particular, grains (soybeans), and secondarily pastures, in which continues with the current expansion. The process as in the past is supported by federal policy, now the PNE - 2030, and receives federal and state subsidies. It's still fast and plays the same model of previous agricultural expansion, occupation of Savannah in the 1970s, differing, however the fastest and well-planned action of large financial groups and the rapid formation of joint ventures and sugar and alcohol agribusiness complexes horizontal extension of those South-East and even multinationals. These groups previously selected areas where expansion triggered the installation of plants inducing a re-zoning, but retained the strategy of producing agricultural commodities. Finally, it was found that the main direct environmental impacts cultivated areas are the loss of soil biodiversity and water resources soil compaction and increase their resistance to penetration, indicating compression, and it is assumed that there is potential for erosion and also the subsequent contamination of their time, because crop management. It was concluded that MRQ experience, paradoxically, both positive and negative social and environmental impacts arising from a rapidly expanding sugarcane which materialized a new centrality of the space sector in the Central Cerrado, similar to that which occurred in the past the state of São Paulo, but this time relying on an industry already established in the south-southeast and which together make up what is called the polygon of the cane and a new center, as part of this arc expansion of sugar cane, as undeniable and great expression of state and national levels, and gradually reference also becoming international.
O setor sucroalcooleiro vem apresentando um processo notável de expansão desde 2000, rumo ao Cerrado central, reconhecidamente favorecido por conjuntura ancorada na defesa da energia renovável e soberania nacional. O estado de Goiás é um dos alvos preferenciais dessa expansão, desde 2004, principalmente 2006-2007, e vem concentrando uma forte agroindústria canavieira na região Sul Goiano/Sudoeste, Microrregião de Quirinópolis (MRQ), onde passou de cerca de 4 mil ha a mais de 150 mil ha plantados no período, com grande impacto na socioeconomia local, segundo estudos anteriores e subsidiários desta tese. Essa microrregião conta com características edafoclimáticas favoráveis e logísticas de grande relevância econômica intra e inter-regional para exportação, porém as mudanças de uso do solo e impactos ambientais relacionados a esse processo ainda são pouco estudados. A presente tese objetiva compreender o padrão espacial de expansão da cana para e na MRQ, com ênfase em solos e suas mudanças de uso, entendidas por vários autores como expansão da Fronteira Agrícola da década de 1970, porém mais organizada, tecnificada e capitalizada, visando comprovar a hipótese de que aí vem se configurando uma nova centralidade do setor sucroenergético no Cerrado, voltado à produção de etanol e bioenergia, cujas consequências multiescalares afetam, dentre outros aspectos, as demais cadeias produtivas pré-existentes, especialmente de produção de alimentos. Analisou-se com mais detalhe a sucessão de usos do solo no período desde 2004, anterior à chegada da cana, de modo a identificar os padrões de substituição de culturas e pastagens pela nova cultura e o potencial de impactos ambientais diretos da cana devida constatação de pressão sobre os recursos hídricos para fins de irrigação e sobre os solos associados ao sistema de manejo de elevado padrão tecnológico, envolvendo insumos e defensivos, além de maquinaria pesada, dentre outros. A pesquisa baseou-se principalmente na compilação de dados e mapas, e elaboração de documentos cartográficos temáticos multiescalares, incluindo uso de imagens de satélite e SIG, análise de dados censitários diversos e estudo detalhado de impactos através de entrevistas dos principais atores, de descrição e coleta de amostras de solos e recursos hídricos e análise laboratorial. Conclui-se que a cana se concentrou inicialmente nas melhores terras da MRQ, onde conta com a melhor infra-estrutura regional/estadual, e vem concorrendo, vitoriosa, com outros usos, em particular, grãos (soja), e secundariamente pastagens, nas quais prossegue com a expansão atual. O processo, como no passado está amparado em política federal, ora o PNE - 2030, e recebe subsídios federais e estaduais. Ainda está acelerado e reproduz o mesmo modelo de expansão da Fronteira Agrícola anterior, de ocupação do Cerrado dos anos de 1970, diferenciando-se, entretanto pela rápida e mais bem planejada atuação de grandes grupos financeiros e formação rápida de joint ventures e complexos agroindustriais sucroalcooleiros horizontais em extensão daqueles do Sul-Sudeste e mesmo multinacionais. Esses grupos selecionaram previamente as áreas de expansão onde desencadearam a instalação das usinas induzindo um novo zoneamento, mas mantiveram a estratégia de produção de commodities agrícolas. Por fim, constatou-se que os principais impactos ambientais diretos nas áreas cultivadas são a perda de biodiversidade dos solos e dos recursos hídricos a compactação dos solos e a aumento de sua resistência à penetração, indicando compactação, e supõe-se que há potencial de erosão subsequente e também de sua contaminação com o tempo, devido manejo da cultura. Conclui-se também que a MRQ vivencia, paradoxalmente, os impactos socioambientais positivos e negativos decorrentes de uma expansão sucroalcooleira que materializou rapidamente uma nova centralidade espacial do setor no Cerrado Central, similar àquela ocorrida no passado no estado de São Paulo, porém desta feita contando com um setor já consolidado no Sul-Sudeste e que juntos se configuram no que se está chamando de polígono da cana e numa nova centralidade, esta como parte do arco de expansão da cana, já de inegável e grande expressão estadual e nacional, e aos poucos se tornando referência também internacional.

The diploma thesis deals with an urban study on the territory of Červený kopec, specifically in the part of the territory of Stráň. It is a locality stated as a brownfield Kohnova cihelna. The proposal aims to make the most of the potential of this site, which lies in its proximity to the city center, the neighborhood of the national natural monument, a significant area of greenery and the views that this place provides due to its topographic situation. A new city district is proposed on the area of 18 hectares, which would cover one of the "brownfield holes" on the map of the city of Brno and at the same time help against the outflow of population to the outskirts of the city and against the creation of urban satellites. Numerous public opinion polls show that they would like to live close to the city, but at the same time especially young families long for their own house in a quiet countryside location. Therefore, a compact development of terraced houses, terrace villas and blocks of flats with private courtyards is proposed here, complemented by quality public space and civic amenities. This new city district would offer housing for about 3,500 new residents.

Dr. Eleine Mad är Madeleine Jacobsssons talesperson för dom vetenskapliga och paranormala upptäckter som uppstår i hennes världar. Hon beskriver innehåll, teknik och estetik utifrån ett kategoriseringssytem där konsten delas upp som olika typer av komponenter och därefter avkodas dessa allteftersom. För att förstå intuitionens inblandning i arbetsprocessen omförvandlas den till tre separata roller av en Sökare, Samlare och Myntare. Med rollerna försöker jag beskriva på vilka sätt som intuitionen är till gagn eller av förödelse för det konstnärliga arbetet. Sagan om M handlar om en grodlik karaktär, Delop, som lämnar sin hemplanet för att uppsöka andra världar. I sitt sökande hittar Delop ett folkslag vars syn och levnadssätt skiljer sig från hennes erfarenheter av “verkligheten” såsom hon lärt sig att överleva i den.Dr. Eleine Mad is Madeleine Jacobsson's spokesperson for the scientific and paranormal discoveries that arise in her worlds. She describes content, tecniques and aesthetics based on a categorization system where art is divided into different types of components and then decoded as they go. To understand the intuition's involvement in the work process, it is transformed into three separate roles by a Seeker, Collector and a Myntare(In swedish language the one who is a "myntare" -is verbally declaring a concept or term). With these roles I try to describe in what ways intuition is beneficial or devastating to the artistic work. The story of M is about a frog-like character, Delop, who leaves the home planet to seek out other worlds. In her search, Delop finds a world whose views and lifestyles differ from her experiences of "reality" as she learned to survive in it.

Urban spaces are an increasingly common indigenous reality, and while urban spaces often
involve great social and geographic distances from traditional communities, many urban
populations have built vibrant communities in cities. This thesis will examine the creation of
Métis cultural spaces in Winnipeg, Manitoba, as a community building strategy. It is situated in
thirteen in-depth interviews with Métis community builders conducted in Winnipeg over the
Summer of 2008. The Winnipeg Metis community is rhizomatic in makeup, situated not in
geographic locations, but in the networks of instantaneous and spontaneous social interaction of
community members and institutions—elders, political organizations and governance structures.
Rhizomatic space is a form of social organization, which emerges out of everyday social life, and
because it is only observable during the brief instances of human interaction, it is nearly invisible
to outsiders and thus difficult to colonize. It is also a primary means by which Métis people are
reclaiming space in their traditional homeland on the Red River. This paper theorizes an
alternative tactic to resistance through a decentered form of political organization, grounded in
the community and its organic institutions. It proposes that the everyday creation of social and
cultural spaces in urban centres is an effective way to build urban indigenous communities with
minimal interference or involvement of the State, and that this develops more or less organically
without the need for bureaucratic oversight. The paper concludes that the everyday creation of
rhizomatic space is a highly effective means of community building and resistance.Thesis (Master, Sociology) -- Queen's University, 2009-08-20 19:43:50.279

Photography is an unstable medium, the repercussions of technological advancement are constantly redefining its capabilities. As an artist working in this medium, I have often found myself wrapped up in existential reflection over my work’s place within the discipline. With At the End of the Spectrum Next to Orange and Opposite Violet, I have narrowed my interests to focus on the phenomenon of light and the manipulation of color. I am creating work committed to the conceptual foundation that light constitutes the experience of a color. I have been working monochromatically to create images and videos in order to explore this idea of color as an experience. Throughout this document my research has opened a new way of thinking about the interactions of light, color, and the viewer.

The Creative Markets in Taiwan, have been developed for 7 years since 2004. And when the creative markets become more famous, the problem comes with its success: the styles of markets are becoming similar, and the products they sold are alike too. Recently, the creative markets fade out because it cannot innovate itself continuously. By now, the creative markets in Taiwan won’t be exist without renewing themselves. The study aims to discuss how the Red House Creative Market in Ximen district innovates itself and attracts more creators to cluster in this area when the creative market grows up, based on 25 in-depth cases interviews with creators in the market, customs, as well as related public and private agencies in Red House Creative Market. And then discuss how the institute of the Red House nurture the creative market and creators by the examine institution and assistant mechanism to help the creators to be on their own, graduate from the market and make their own business. In this case, the actors in Red house creative markets interflow, compete, interact, and learn. By all of these, the actors make the market full of knowledge and technology. Also, the related association who make the Red House happen is important: The Taipei Cultural Foundation, Art and Lifestyle Association of Taiwan, creators in market and the customers. Because of all the mentioned actors in the market, the creative market is now full of ideas, interactions and learning system. Above all, in the case of Red House creative market, evidences show that it is informal learning mechanisms, especially those embedded within its established local and global knowledge channels, that support Red House creative market sustained upgrading capability.

Using the analytical framework on civic spaces provided by Mike Douglass, this paper examines how the mixture of sectors came out on “Hong Low Guan Chang (Ximen Red House Square)” changed the face of contemporary urban gay lives in Taipei. First, the negotiation between city governors and gay café managers points out that even if gay community brought the revival of a forgotten area, gay business is still a taboo in official urban plan. Second, the heteronormativity seems to fade out in the area; however, the differed gay performativity still reveals uneven power in between gay individuals including the bears, the sissies, and the transgender. Third, based on current organizational framework of gay café and service providers, the dissertation suggests the possibilities of opening up a new route of gay right movements in Taipei.

To wield direct influence on the everyday lives of citizens, new political elites have often professed a profound interest in shaping the politics of dwelling. In the 1920s, Vienna’s Social Democrats built 400 communal housing blocks equipped with public gardens, theaters, libraries, kindergartens, and sports facilities, hoping that these facilities would serve as loci for “growing into socialism”. In the 1950s, housing construction in Berlin became a site of the Cold War. East Berlin’s social realist “workers palaces” on Stalinallee were meant to serve as an ideal flourishing ground for the “new socialist men and women”. In contrast, West Berlin's modernist Hansa-Viertel was designed to showcase an ideal dwelling culture and an urban environment that would cultivate individuality.
This dissertation examines three historically situated and ideologically distinct responses to the housing question: social democracy in Red Vienna, state socialism in East Berlin, and liberal capitalism in West Berlin. It illuminates how political promises of a radical new beginning were translated into spatial arrangements—the private scale of the apartment and the urban scale of the city—as well as how citizens appropriated the social, political, and economic norms inherent to the new spaces they inhabited. More specifically, the following analyses demonstrate the fact that inherited social, technological, and economic practices have often subverted political visions of a radically different future. This was the case with pedagogy in Red Vienna’s municipal housing, instrumental reason in the form of Taylorism and Fordism in East and West Berlin’s mass housing, and gender relations in Red Vienna’s and East Berlin’s politics of dwelling. At the same time, this dissertation examines counter-spaces that emerged from the dialectics between political promises and actual socio-spatial realities, counter-spaces that both reflect critically on past hegemonic “politics of dwelling” and that foreshadow alternative political imaginations that are still relevant today. Of particular interest are counter-hegemonic practices of dwelling that embody possibilities of emancipation—of experiencing oneself as subject instead of object of social transformation, justice—of emphasizing considerations of equality and recognition, and radical democracy—of questioning power relations and of forming alliances among disadvantaged groups to transform everyday life.

Due to intensive coastal development, a combination of local (e.g. pollution, fishing) and global pressures (such as climate change) is affecting marine habitats worldwide. This is a pressing issue in Saudi Arabia, particularly considering the plans for the expansion of sea-related activities within the Saudi Arabia's Vision 2030 framework. Sustaining some of those activities, such as tourism, is dependent upon the maintenance of good ecosystem health. National monitoring programs in Saudi Arabia are scarce and a lack of sound knowledge on how marine organisms change in space and time and what the main factors driving their responses are, limits the contribution of scientists to the management and conservation of the Red Sea. Here we provide baseline knowledge, that can be critical for assessing changes associated with current and future coastal development as well as climate change by collecting data across multiple spatial (including multiple habitats) and temporal scales for the analysis of macroinvertebrate organisms and environmental drivers. One of the most striking findings is related to the low densities observed for macroinvertebrates, making populations potentially vulnerable to disturbance. We also highlight the contribution of different habitats within the seascape and the need to prioritize the features of the bottoms for management and conservation purposes. Each habitat has a unique ecological signature but they are connected to adjacent habitats through a subset of species able to utilize different biotopes within the seascape. Disrupting this ecological network may affect biodiversity patterns from local to regional levels. Within each habitat, temporal variability should be taken into account as patterns change on a seasonal and annual scale. The aim of the thesis is to contribute to the sustainable development of the Red Sea, a unique resource shared among several countries, which will result in a long-term benefit to the Kingdom of Saudi Arabia, and other countries. Information provided is critical as previous knowledge for the region was almost inexistent and allows for future studies to investigate and predict the impacts of intense coastal development and inform conservation and management decisions.
