Disaster Risk Reduction contribution to Peacebuilding programmesLozano Basanta, Juan Alfonso January 2014 (has links)
The aim of this thesis is to provide theoretical evidence that a disaster risk reduction perspective within peacebuilding programmes, particularly in countries where disasters and conflict overlap, can contribute positively to the transformation of conflict into sustainable peace. An increasing number of disasters in fragile states and countries affected by armed conflict has brought the attention to know in which way disasters and conflicts collide when they come to occur in the same area, and how disasters can influence on-going peace processes. In order to demonstrate that argument the thesis draws the evolution of the disaster risk management models and peacebuilding frameworks along the last decades and make use of a comprehensive theoretical background to support the subsequent analysis. This thesis contributes to the academic literature and humanitarian reports of studies describing the relation between disasters and conflict but, more concretely, it aims to fill the gap in research studying the links between a disaster risk reduction strategy and peacebuilding programmes. The conclusions of the thesis are that disaster risk reduction initiatives contribute positively in several ways to the different key areas of peacebuilding programmes either as concrete initiatives or as a crosscutting issue. / El objeto de esta tesis es proporcionar sustento teórico a la idea de que una perspectiva de reducción de riesgos de desastre en el marco de programas de construcción de paz puede contribuir positivamente a transformar el conflicto en una paz sostenible, particularmente en países donde desastres naturales y conflicto confluyen. Un número creciente de desastres naturales que acontecen en estados frágiles o países afectados por conflicto armado atrae la atención de profesionales y académicos del ámbito humanitario con el fin de conocer mejor el modo en que conflicto y desastre natural se influyen mutuamente. Esta tesis describe la evolución en las últimas décadas de los modelos de gestión de riesgos de desastre y los marcos operacionales de construcción de paz, además, se sustenta en una amplia base teórica para llevar a cabo el análisis pertinente. La intención es contribuir modestamente a la literatura académica que se ocupa de estudiar la ayuda humanitaria, así como tratar de colaborar en encontrar posibles vínculos entre una estrategia de reducción de riesgos de desastre y los programas de construcción de paz. Las conclusiones de esta tesis indican que las iniciativas de reducción de riegos de desastre contribuyen positivamente en distintos aspectos de las áreas de trabajo de los programas de construcción de paz, ya sea como actividades concretas o como un eje transversal a todo el programa.

Semen decontamination for the elimination of seminal pathogensFourie, Jozef Markus January 2013 (has links)
The presence of pathogens in semen can compromise the outcome of assisted reproductive treatment, together with the possibility of the female partner or offspring becoming infected. This is cause for concern, especially in South Africa with a high prevalence of HIV-1. Most of these infected individuals are in their reproductive years with the desire to have their own genetically related children. Therefore, assisted reproductive treatment with effective risk reduction procedures, such as semen processing for the elimination of these pathogens is crucial.
However, during sperm preparation by standard discontinuous density gradient centrifugation, the supernatant is aspirated to allow access to the purified sperm pellet. Pathogens from the upper layers can adhere to the inside surface of the test tube and flow down to re-infect the purified sperm sample. The use of a centrifuge tube insert may prevent the re-contamination of sperm samples after discontinuous density gradient centrifugation. Furthermore, seminal pathogens can bind specifically or non-specifically to spermatozoa, rendering semen decontamination procedures ineffective. Serine proteases, such as trypsin, have been demonstrated to effectively inactivate viruses and to break pathogen-sperm bonds. However, the addition of a protease to density gradient layers during semen processing could have a negative impact on sperm parameters. This research was therefore aimed towards the determination of:
i) The effect of semen processing with trypsin and trypsin inhibitor on sperm parameters.
ii) The prevalence of various bacteria in semen samples from men attending the Reproductive and Endocrine Unit at Steve Biko Academic Hospital.
iii) The effectiveness of semen processing by discontinuous density gradient centrifugation with a centrifuge tube insert, for the elimination of some of the most prevalent bacteria, white blood cells and in vivo derived HIV-1.
Evaluation of sperm parameters after semen processing indicated that trypsin and trypsin inhibitor did not have an impact on sperm mitochondrial membrane potential, vitality, motility and zona binding potential, or acrosin activity, respectively. Seminal bacteria were highly prevalent in patients wishing to participate in the Unit’s assisted reproductive program, with 49.5% of semen samples presenting with positive bacterial cultures. Semen processing by means of discontinuous density gradient centrifugation with the tube insert, eliminated significantly more in vitro derived (spiked) bacteria and white blood cells from semen compared to processing without the insert. Furthermore, the semen decontamination procedure was effective in removing HIV-1 RNA from 100% of samples and proviral DNA from 98.1% of semen samples from HIV-1 sero-positive patients.
The effectiveness of discontinuous density gradient centrifugation for the elimination of seminal pathogens could, therefore, be improved by the addition of trypsin to the upper density layer, without supplementing the bottom layer with trypsin inhibitor. Additionally, semen decontamination efficiency could also be improved by the prevention of re-contamination of processed sperm samples by the utilization of a tube insert during discontinuous density gradient centrifugation. / Thesis (PhD)--University of Pretoria, 2014. / gm2014 / Obstetrics and Gynaecology / unrestricted

Public-private partnerships in disaster management: A case-study of the city of cape town / A mini-thesis submitted to the School of Government, Faculty of Economic and ManagementBuwa, Mbulelo M. January 2012 (has links)
Masters in Public Administration - MPA / Greater capacity for cities to be disaster resilient is needed. Public-private partnership
enhances municipal capacity. This study therefore, interrogates the relationship between the
City of Cape Town and its disaster relief partners. It is mainly concerned with policy
implementation, and as such, investigates disaster management policy implementation in
relation to public-private partnerships.
The objectivesof the study were to provide a conceptual framework that defines the terms
eminent in the practice and study of disaster management, particularly those that characterize
public-private partnerships in the City of Cape Town; to explore the legislative mandate that
makes provisions for disaster management and the funding of public-private partnerships in
municipalities; to document the current practice of public-private partnerships in the City of
Cape Town; to highlight noted challenges in the partnership and where necessary,
recommend alternative policy implementation options for enhanced partnership sustainable
capacity for disaster relief.
The researcher deemed it expedient to utilize the qualitative method for the purposes of the
adeptness it affords in expediting malleable, arduous investigation in engaging with the
phenomena that “unfold[s] in real-world situations.”
As far as the findings of this study are concerned, the public-private partnership of the City of
Cape Town with its disaster relief partners is a successful one. It is effective in bringing the
much needed awareness and relief to devastated communities. There are four main
challenges that impact on this disaster relief partnership have been realized by this study. These namely are the delays in the reimbursement process, the constant change of
government personnel dealing with relief partners, absence of a disaster relief official on the
sites of distress and unsubsidized expenses incurred by the relief partners. Having realized
these challenges, the study makes policy implementation recommendations.

Možnosti poskytování harm reduction a léčebných intervencí uživatelům konopných drog v kontaktních centrech a terénních programech: kvalitativní analýza názorů pracovníků v Praze a Středočeském kraji / Possibilities of providing harm reduction and therapeutic interventions to cannabis users in drop-in centres and outreach programmes: qualitative analysis of employee opinions in Prague and Central Bohemian RegionPúčiková, Dominika January 2017 (has links)
Introduction:. In 2014, there were 180 thousand problematic users of drugs in the Czech Republic. Action plan of the realisation of National strategy of anti-drug politics in the Czech Republic concentrates on lowering the degree and risk of marijuana usage, while in the first period no specific programs for target group have been realised. In 2015, 2400 marijuana consumers were using low-threshold treatment programs. Topic of cannabis related drug users in drop-in centres and outreach programs appears at the expert meetings, though there is a lack of systematically developed material, which would be include good practice of low- threshold treatment programs for the target group. Aim: Primary aim of thesis is to provide a qualitative analysis of opinions of drop-in centers and outreach programs employees in Prague and Central Bohemian region regarding the possibility of offering harm reduction and therapeutic interventions to cannabis users. Thesis could serve as a summary of good practice of harm reduction services in the Czech Republic and become a material that could help individual services in the formulation of concept, respectively in changing and evaluating the work with cannabis users. Methodology: Data were collected via semi-structured interviews and were subsequently analysed using...

Informal Urban Displacement in Rio de Janeiro: Ecolimits and Disaster Biopolitics in the Favela Santa MartaHeck, Charles L 09 November 2016 (has links)
This dissertation examines the effect of environmental discourse and disaster risk reduction mapping in the favela Santa Marta, an urban informal settlement in the municipality of Rio de Janeiro, Brazil. With the world’s largest urban forest within the metro area, Rio de Janeiro is unusual for a metropolis of more than ten million people in the rapidly urbanizing country of Brazil. The government of Rio de Janeiro has attempted to control favela settlements since the early 20th century, but beginning in the 1990s the prefecture began delimiting favela settlements with environmentally protected areas called ecolimits. According to the state’s calculations, in the 2000s favelas began to rapidly expand into the urban forest, which is protected by the ecolimits and national parks. In 2009, the state built a wall around Santa Marta, justified by concerns about expansion into the adjacent forest. The state then labeled Santa Marta the model favela after infrastructure improvements there and the installation of the first Pacification Police Unit, a new form of community policing begun in 2008 for favelas.
The focus of my study is the particular ways that the government has framed its resettlement efforts in Santa Marta and how favela residents responded. I employ the concept of biopolitics assemblage to critically investigate the state’s and international institutions’ discursive and material practices of disaster risk management in Santa Marta. I collected data using a mixed methods approach during 15 months of fieldwork. Through archival research, I document the history of favela control tactics and trace the roots of disaster risk management in Rio de Janeiro to a World Bank financed disaster response project initiated in 1988. Using ethnographic methods, I documented residents’ responses to and understandings of the government’s resettlement project for Santa Marta. My results indicate that the state has discursively shifted the problem of favelas from a social question to an environmental one, while residents continue to frame favela conditions as a social justice issue and challenge the state’s assessment of environmental risk.

Rôles adaptatifs et contraintes de la sporulation chez les microorganismes associés aux plantes : cas de la sporulation in planta dans la symbiose actinorhizienne Frankia (Frankiaceae)–Alnus (Betulaceae) / Adaptive roles and constraints of the sporulation in plant-associated microorganisms : case of the in-planta sporulation in the actinorhizal symbiosis Frankia (Frankiaceae)–Alnus (Betulaceae)Pozzi, Adrien C. 18 December 2014 (has links)
Frankia est une actinobactérie capable d'établir une symbiose racinaire avec les plantes actinorhiziennes dont le genre Alnus. Seulement certaines souches de Frankia sont capables de sporuler in planta, ce qui est illustré par la présence (Sp+) ou l'absence (Sp–) de sporanges dans les cellules végétales de la nodosité. C’est à notre connaissance un cas unique de sporulation endophyte. Cependant la description et l’interprétation écologique de ce trait d’histoire de vie (THV) original étaient incomplètes. Notre contribution à l’étude de la sporulation in planta des Frankia infectives de l’aulne intègre des approches théorique, descriptive et expérimentale, pour préciser (i) l’influence relative de la souche bactérienne, de l’espèce de la plante-hôte et des conditions pédoclimatiques sur ce THV, (ii) le rôle de la variabilité environnementale sur la distribution, la diversité et la sélection du trait, ainsi que (iii) les coûts et bénéfices associés pour les deux partenaires. Nous avons démontré pour la première fois que la sporulation in planta est un THV (i) spécifique de certaines lignées de Frankia, (ii) majeur pour en comprendre l'histoire évolutive et (iii) significativement corrélé à des caractéristiques génétiques des souches. Nous avons également confirmé que l’occurrence du trait varie selon l’environnement. Nous avons enfin établi un modèle de l'évolution du trait abordant sa valeur adaptative. L’ensemble des réflexions menées et des résultats obtenus nous permet de discuter de la sporulation in planta dans le cadre d’un continuum de stratégies symbiotiques, et plus généralement de discuter de l’écologie évolutive des symbioses entre microorganismes et plantes / Frankia sp. is a telluric actinobacteria able to establish a root symbiosis with actinorhizal plant such as Alnus sp. Only some Frankia strains are able to sporulate in-planta, as spores can be present in (Sp+) or absent from (Sp–) the vegetal cells of the root nodule. It is to our knowledge a unique case of endophytic sporulation. However, the description and the ecological interpretation of this original life-history trait (LHT) were scarce. Our contribution to the study of the in-planta sporulation of Alnus-infective Frankia sp. combines theoretical, descriptive and experimental approaches to precise (i) the relative effect of the bacterial strain, the host-plant species and the pedoclimatic conditions on this LHT, (ii) the effect of the of the environmental variability on the distribution, diversity and selection of the trait, and (iii) the associated costs and benefits for the two symbiotic partners. We demonstrated for the first time that the in-planta sporulation is a LHT (i) specific to some Frankia lineages, (ii) major to understand their evolutionary history and (iii) significantly correlated to particular genetic features. We also shown that the occurrence of the trait varies according to the environment We also proposed a model of the evolution of the trait taking its fitness into account. We bring all the previous considerations and results to discuss the inplanta sporulation trait within a continuum of symbiotic strategies and more generally to discuss the evolutionary ecology of plant-microbe symbioses

A review of the implementation of disaster risk assessments in the city of Cape Town: challenges and prospectsWhite, Deon Robin January 2013 (has links)
Masters in Public Administration - MPA / The problem question of this study is how the City of Cape Town, as a metro municipality went about implementing Disaster Risk Assessments. While the National Disaster Management Centre acknowledges that municipalities are battling to perform Disaster Risk Assessments. Understanding what was done, by whom and when will aid in the understanding of implementing Disaster Risk Assessments. Uncovering the prospects and challenges they faced and will help shed light on the guidance that is required by other municipalities, although this study’s inference is limited by the methodology. The relatively new Disaster Management Act requires a shift from old civil defence legislation to a proactive disaster risk reduction mode, with new institutional arrangements. The shift to a proactive disaster risk reduction approach required by the new legislation cannot be achieved without firstly implementing these new institutional and policy arrangements and secondly, implementing this first and vital step in the disaster risk reduction process namely, Disaster Risk Assessments. The study also seeks to understand in the community was involved. This is a qualitative study, i.e. it contains descriptive statistics and narratives. It used questionnaires to provide numerical and descriptive data to measure compliance to the Disaster Management Act in terms of the institutional arrangements implemented by the City of Cape Town. Secondly, qualitative data was collected through semi-structured interviews to provide data to understand the challenges and prospects encountered in performing Disaster Risk Assessments. A literature review was also undertaken to highlight the current debates in Disaster Risk Reduction. The stratified sample was from the officials employed at the City’s Disaster Management Centre, Area Managers, NGOs, Ward Councillors and Consultants. The data was collated and the analysed. The objective is to primarily understand what was done, by whom, when and secondly to understand the prospects and challenges faced. The findings, recommendations and areas of future study are captured in this research report.

Increasing the Supply of the Missing Middle Housing Types in Walkable Urban Core Neighborhoods: Risk, Risk Reduction and CapitalOjah Maharaj, Shrimatee 30 March 2019 (has links)
There is a low supply of the missing middle housing types (MMH) in walkable urban core neighborhoods. That is, a variety of compact low- to mid-rise housing in walkable areas that are accessible to entertainment, recreational and other amenities. The largest demographic, the millennials, followed by the baby boomers, prefer the MMH types. The MMH types is a new name for a variety of compact housing types that existed in traditional neighborhoods in urban areas pre-World War II. However, due to changes in housing preferences after World War II, the requisite land use and zoning changes facilitated larger single-family homes phasing out the MMH types. Efforts to reintroduce the MMH types is these areas are met with opposition.
This research investigates increasing the supply of the MMH types in walkable urban core neighborhoods. The literature review reveals, prior to this one, no academic study at this level was done to understand how to increase the supply of MMH types in these areas.
This research explores the views of stakeholders in urban planning and various professions related to housing and the MMH types in the Tampa Bay Area, to better understand the issues involved in the low supply of the MMH types in urban core areas.
The data for this qualitative research was guided by a grounded theory methodology (Corbin & Strauss, 2014) and was derived from thirty-nine semi-structured interviews with stakeholders to find out what factors inhibit and ways to improve the supply of the MMH types in the Tampa Bay area.

Flood Warnings in a Risk Management Context : A Case of Swedish MunicipalitiesPersson, Erik January 2015 (has links)
As a result of the United Nations’ International Decade for Natural Disaster Reduction (1990-2000), and recent high profile disasters, disaster risk reduction has climbed high on the international political agenda. There has been a paradigm shift from reacting to disasters towards preparing for and mitigating effects of disasters. Among the measures that have been highlighted on the disaster risk reduction agenda are early warning systems. In a Swedish context, there are needs for early warnings for various flood risk types. Municipalities carry big responsibilities for managing flood risks, and early warnings have a potential to facilitate decision-making and ultimately reduce flood losses. The aim of this thesis is to describe how a variety of flood warning signals are used in the risk management process of Swedish municipalities, how they can contribute to the flood risk reducing process, and which factors influence the success of this. The thesis is based on two papers. Paper I is based on interviews with three respondents from Swedish municipalities that have invested in and established local early warning systems. The paper shows that the possible effects from a local early warning system are not only reduced flood losses but also potential spinoff, the occurrence of which is dependent on the well-being of the organisation and its risk management processes. Paper II is based on interviews with 23 respondents at 18 Swedish municipalities, who have responsibilities related to flood risk management, and one respondent who works at SMHI with hydrological warning. The paper shows that municipalities can use a variety of complementary flood warning signals to facilitate decision-making for a proactive flood response. This is however not systematically the case, and is dependent on available resources. The theoretical contribution of this thesis is a development of existing conceptual models of early warning systems with respect to risk management and system contexts, and the use of complementary warning signals. / Following the United Nations’ International Decade for Natural Disaster Reduction (1990-2000), and recent high profile disasters, disaster risk reduction has climbed high on the international political agenda. Among the measures that have been highlighted are early warning systems – for Swedish municipalities who are responsible for managing flood risks, early warnings have a potential to facilitate decision-making and ultimately reduce flood losses. This licentiate thesis, based on two articles, aims to describe how a variety of flood warning signals are used in the risk management process of Swedish municipalities, how they can contribute to the flood risk reducing process, and which factors influence the success of this. The articles show that the possible effects from a local early warning system are not only reduced flood losses but also potential spin-off benefits, the occurrence of which is dependent on factors such as organisational culture and the functioning of the wider risk management system, and that municipalities can use a variety of complementary flood warning signals to facilitate decision-making for a proactive flood response which, however, is not systematically the case as benefits are dependent on available resources.
