description: Presently, there are several experimental setups dedicated to rare event searches, such as dark matter interactions or double beta decay, in the building or commissioning phases. These experiments often use large mass detectors and have excellent performance in terms of energy resolution, low threshold and extremely low backgrounds. In this paper we show that these setups have the possibility to exploit coherent scattering on nuclei to detect neutrinos from galactic supernova explosions, thus enlarging the number of early detection "observatories" available and helping in the collection of valuable data to perform flavour-independent studies of neutrinos' emission spectra.

Zinc depletion-induced apoptosis is associated with altered microRNA expression in human breast cancer MDA-MB-231 cells
Creators: name: Bakker, Melinda

description: Zinc is an essential trace element required for many physiological functions, including growth. At the cellular level, zinc is required for structural and catalytic roles in thousands of proteins, and adequate labile zinc is an important determinant of cellular viability. However, abnormal zinc accumulation in breast tissue is associated with breast cancer, suggesting that zinc status plays a role in breast cancer pathogenesis. Chelationinduced depletion of labile intracellular zinc promotes apoptosis, or programmed cell death, in multiple breast cancer cell lines. The mechanisms whereby zinc regulates apoptosis remain unclear. In particular, little is known about the role of microRNAs (miRs), a novel class of short non-coding RNA, involved in the regulation of gene expression. Zinc status can influence miR expression, and possibly the processing and stability of miRs. The hypothesis of my thesis research is that miRs are involved in zinc depletion-induced apoptosis in human breast cancer cells. The overall objective of this study was to determine the involvement of miRs in zinc depletion-induced apoptosis in breast cancer MDA-MB-231 cells. Zinc depletion for 24, 48 and 72 h induced apoptosis in 4.5, 24.4 and 28.0 % of the cells, respectively, indicating a time-dependent increase in zinc depletion-induced apoptosis. Expression of 8, 90, and 94 miRs were significantly altered during the early stages of zinc depletion-induced apoptosis, at 3, 12, and 24 h of zinc depletion, respectively. Overall, expression of 285 unique miRs was significantly affected by zinc depletion, duration of zinc depletion, and their interactions. qRT-PCR analysis confirmed that zinc depletion resulted in an increased abundance of miR-132-3p, miR-1246, miR-1273, miR-4484 and miR-4787-5p and a decreased abundance of miR-4521 in a time-dependent manner. MiR-132-3p and miR 1246 have previously been shown to play a role in mediating apoptosis in prostate cancer PC-3 and lung cancer A549 cells, respectively. In conclusion, abundance of numerous miRs was altered during the early stages of zinc depletion-induced apoptosis, indicating possible involvement of these miRs in mediating zinc depletion-induced apoptosis. The role and targets of these miRs in zinc depletion-induced apoptosis requires validation in further research.

description: We explore the Reissner-Nordström naked singularities with a charge $Q$ larger than its mass $M$ from the perspective of the particle acceleration. We first consider a collision between two test particles following the radial geodesics in the Reissner-Nordström naked singular geometry. An initially radially ingoing particle turns back due to the repulsive effect of gravity in the vicinity of naked singularity. Such a particle then collides with an another radially ingoing particle. We show that the center of mass energy of collision taking place at $r \approx M$ is unbound, in the limit where the charge transcends the mass by arbitrarily small amount $0<1-M/Q\ll1$.The acceleration process we described avoids fine tuning of the parameters of the particle geodesics for the unbound center of mass energy of collisions and the proper time required for the process is also finite. We show that the coordinate time required for the trans-Plankian collision to occur around one solar mass naked singularity is around million years while it is many orders of magnitude larger than Hubble time in the black hole case. We then study the collision of the neutral spherically symmetric shells made up of dust particles. In this case, it is possible to treat the situation by exactly taking into account the gravity due to the shells using Israel`s thin shell formalism, and thus this treatment allows us to go beyond the test particle approximation. The center of mass energy of collision of the shells is then calculated in a situation analogous to the test particle case and is shown to be bounded above. However, we find thatthe energy of a collision between two of constituent particles of the shells at the center of mass frame can exceed the Planck energy.

description: In der vorliegenden Arbeit werden das plastische Verformungsverhalten, die Dehnratenabhängigkeit der Fließspannung und die mikroskopischen Verformungsstrukturen der einkristallinen intermetallischen Verbindung MoSi2 untersucht. Die Untersuchungen beschränken sich auf das {110}/-Gleitsystem, von dem aus der Literatur bereits bekannt ist, dass die zugehörige Fließspannung bei mittleren Verformungstemperaturen anomal ansteigt. Damit soll der aktuellen Fragestellung nach den grundlegenden, temperaturabhängigen mikroskopischen Mechanismen, welche die plastische Verformung in MoSi2 bestimmen, Rechnung getragen werden. Die Fragestellung schließt den Bereich der Fließspannungsanomalie ein. Im Verlauf makroskopischer Druckversuche werden durch Spannungsrelaxations- und Dehnratenwechsel- Versuche die Aktivierungsparameter des Versetzungsgleitens bestimmt, mit deren Hilfe eine Charakterisierung der Verformungsprozesse unter bestimmten Voraussetzungen möglich ist. Das temperaturabhängige dynamische Verhalten der Versetzungen wird in In-situ-Dehnexperimenten in einem Höchstspannungs-Elektronenmikroskop (HVEM) analysiert. Es wird ein Modell zur Interpretation des Verformungsverhaltens durch Aktivierung des {110}/-Gleitsystems bei mittleren Temperaturen, also im Bereich der Fließspannungsanomalie, vorgestellt.
description: Emphasis of the presented work is the investigation of the plastic deformation behaviour, the strain rate sensitivity of flow stress and microscopic deformation structures of the single crystalline intermetallic compound MoSi2. The investigation is limited to the {110}/ slip system from which an anomalous increase of the yield stress at intermediate temperatures is already known from literature. The presented results may help to answer questions for the fundamental microprocesses controlling the temperature dependent mobility of dislocations including the range of flow stress anomaly. Stress relaxation and strain rate cycling tests were performed during compression tests in order to determine the activation parameters of dislocation glide. By means of this parameters and under special assumptions it is possible to characterize the microscopic deformation processes. The temperature dependent dynamic behaviour of dislocations is analysed by in-situ straining experiments in a high-voltage electron microscope. A model is presented to interpret the deformation behaviour by activation of the {110}/ slip system at intermediate temperatures, the temperature range of flow stress anomaly.

description: In the present paper we investigate the Hawking radiation of asymptotically non-flat dyonic black holes in 4D Einstein-Maxwell-dilaton gravity in semi-classical approximation. We show that the problem allows an exact analytical treatment and we compute exactly the semi-classical radiation spectrum of both non-extremal and extremal black holes under consideration. In the high frequency regime we find that the Hawking temperature does not agree with the surface gravity when the magnetic charge is nonzero. Even more surprisingly the Hawking temperature is independent of the black hole intrinsic characteristics, as the mass and magnetic charge, and depends only on the linear dilaton background parameter.

description: In this paper,,an economic SiGe HBT (hetero- junction bipolar transistor)process using reduced pressure chemical vapor deposition (RPCVD)process of high throughput and the cheap localized oxidation of silicon (LOCOS)instead of shallow trench,was developed and characterized.To test its feasibility,several low noise amplifiers were designed and fabricated.As well as high cutoff frequency and low noise SiGe HBT devices,the passive elements including planar spiral inductors with only two metal layers,metal-insulator-metal capacitor,three kinds of resistors,and varactor diode were also integrated in the process.With carefully designing of the base profile and  adopting finger-type structure,the measured minimum noise  figure of 1.5 dB and associated gain of 16 dB at 1.8 GHz  consuming the collector current of 4.6 mA at the supply voltage of 2.5V,were obtained in the low noise device.After on-wafer calibration,one of the fabricated low noise amplifiers was measured as 2.5 dB NF and 21 dB insertion  gain at the frequency of 1.8 GHz with the supply voltage of 2.5 V.Those results using the epitaxial growth by RPCVD are firstly reported,and show its possibility to RF arena.

description: We study sequential tunneling through a metallic nanoparticle close to the Stoner instability coupled to parallely magnetized electrodes. Increasing the bias voltage successively opens transport channels associated with excitations of the nanoparticle's total spin. For the current this leads just to a steplike increase. The Fano factor, in contrast, shows oscillations between large super-Poissonian and sub-Poissonian values as a function of bias voltage. We explain the enhanced Fano factor in terms of generalized random-telegraph noise and propose the shot noise as a convenient tool to probe the mesoscopic Stoner instability.

description: The recently proposed two families of strongly intensive measures of fluctuations and correlations are studied within Hadron-String-Dynamics (HSD) transport approach to nucleus-nucleus collisions. We consider the measures $Δ^{Kπ}$ and $Σ^{Kπ}$ for kaon and pion multiplicities in Au+Au collisions in a wide range of collision energies and centralities. These strongly intensive measures appear to cancel the participant number fluctuations. This allows to enlarge the centrality window in the analysis of event-by-event fluctuations up to at least of 10% most central collisions. We also present a comparison of the HSD results with the data of NA49 and STAR collaborations. The HSD describes $Σ^{Kπ}$ reasonably well. However, the HSD results depend monotonously on collision energy and do not reproduce the bump-deep structure of $Δ^{Kπ}$ observed from the NA49 data in the region of the center of mass energy of nucleon pair $\sqrt{s_{NN}}= 8÷12$ GeV. This fact deserves further studies. The origin of this `structure' is not connected with simple geometrical or limited acceptance effects, as these effects are taken into account in the HSD simulations.

Cyberpsychology and schools : a feasibility study using virtual reality with school children

Publisher: name: University of British Columbia

description: This study evaluates the feasibility and treatment acceptability of Virtual Reality (VR) technology applied universally in a school setting. A total of 105 children, mean age of 14.45, in five classrooms completed a paper and pencil measure of trait anxiety during Session 1. In Session 2, participants were randomly selected to participate in either a neutral environment or an anxiety-provoking environment and completed a measure of state anxiety immediately prior to and following their first VR exposure. Following the exposure participants also completed a Likert-Scaled questionnaire regarding treatment acceptability. In Session 3, participants completed Session 2 procedure in the alternate environment. There was a main effect of condition and time on state anxiety scores, controlling for trait anxiety. Participants in the anxiety provoking condition had lower mean state anxiety scores than being in the neutral condition; participants had lower state anxiety levels following the anxiety condition than they did following the neutral condition. All participants’ mean state anxiety levels were lower post exposure than pre exposure. There was also a borderline significant main effect of condition on treatment acceptability levels, controlling for trait anxiety. Participants in the neutral condition had a higher level of acceptability than when in the anxiety provoking condition. Results reveal that the implementation of VR technology exposure warrants further research.
Towards consistent mapping of distant worlds: secondary-eclipse scanning of the exoplanet HD189733b

description: Mapping distant worlds is the next frontier for exoplanet infrared photometry studies. Ultimately, constraining spatial and temporal properties of an exoplanet atmosphere will provide further insight into its physics. For tidally-locked hot Jupiters that transit and are eclipsed by their host star, the first steps are now possible. Our aim is to constrain an exoplanet's shape, brightness distribution (BD) and system parameters from its light curve. Notably, we rely on the eclipse scanning. We use archived Spitzer 8-μm data of HD189733 (6 transits, 8 secondary eclipses, and a phase curve) in a global MCMC procedure for mitigating systematics. We also include HD189733's out-of-transit radial velocity measurements. We find a 6-σ deviation from the expected occultation of a uniformly-bright disk. This deviation emerges mainly from HD189733b's thermal pattern, not from its shape. We indicate that the correlation of the orbital eccentricity, e, and BD (uniform time offset) does also depend on the stellar density, ρ*, and the impact parameter, b (e-b-ρ*-BD correlation). For HD189733b, we find that relaxing the e-constraint and using more complex BDs lead to lower stellar/planetary densities and a more localized and latitudinally-shifted hot spot. We obtain an improved constraint on the upper limit of HD189733b's orbital eccentricity, e<0.011 (95%), when including the RV measurements. Our study provides new insights into the analysis of exoplanet light curves and a proper framework for future eclipse-scanning observations. Observations of the same exoplanet at different wavelengths will improve the constraints on its system parameters while ultimately yielding a large-scale time-dependent 3D map of its atmosphere. Finally, we discuss the perspective of extending our method to observations in the visible, in particular to better understand exoplanet albedos.

description: We present a semi-analytic method for the integrand reduction of one-loop amplitudes, based on the systematic application of the Laurent expansions to the integrand-decomposition. In the asymptotic limit, the coefficients of the master integrals are the solutions of a diagonal system of equations, properly corrected by counterterms whose parametric form is konwn a priori. The Laurent expansion of the integrand is implemented through polynomial division. The extension of the integrand-reduction to the case of numerators with rank larger than the number of propagators is discussed as well.

Dynamical Tides in Compact White Dwarf Binaries: Tidal Synchronization and Dissipation

Year: 2011

description: In compact white dwarf (WD) binary systems (with periods ranging from minutes to hours), dynamical tides involving the excitation and dissipation of gravity waves play a dominant role in determining the physical conditions of the WDs prior to mass transfer or binary merger. We calculate the amplitude of the tidally excited gravity waves as a function of the tidal forcing frequency ω=2(Ω-Ω_s) (where Ωis the orbital frequency and Ω_s is the spin frequency) for several realistic carbon-oxygen WD models, assuming that the waves are efficiently dissipated in the outer layer of the star by nonlinear effects or radiative damping. The mechanism of wave excitation in WDs is complex due to the sharp features associated with composition changes inside the WD, and in our WD models gravity waves are launched just below the helium-carbon boundary. We find that the tidal torque on the WD and the related tidal energy transfer rate, \dot E_{\rm tide}, depend on ωin an erratic way. On average, \dot E_{\rm tide} scales approximately as Ω^5ω^5 for a large range of tidal frequencies. We also study the effects of dynamical tides on the long-term evolution of WD binaries. Above a critical orbital frequency Ω_c, corresponding to an orbital period of order one hour (depending on WD models), dynamical tides efficiently drive Ω_s toward Ω, although a small, almost constant degree of asynchronization (Ω-Ω_s\sim {\rm constant}) is maintained even at the smallest binary periods. While the orbital decay is always dominated by gravitational radiation, the tidal energy transfer can induce significant phase error in the low-frequency gravitational waveforms, detectable by the planned LISA project. Tidal dissipation may also lead to significant heating of the WD envelope and brightening of the system long before binary merger.

description: Traditionell werden ökonomische Experimente im Labor durchgeführt. In der letzten Zeit nimmt die Bedeutung von Extralaborexperimenten zu. Extralaborexperimente sind Experimente, die von der Laborumgebung abweichen. Dazu zählen internetbasierte Experimente. Diese ermöglichen es, Untersuchungen unabhängig von räumlichen Restriktionen durchzuführen. Zu den (internetbasierten) Individualexperimenten zählen Unternehmensplanspiele. Bei Unternehmensplanspielen werden die Teilnehmer mit einem realweltlichen Kontext konfrontiert und ihr Verhalten über mehrere Perioden beobachtet. In vielen Bereichen des Lebens werden verlässliche Abschätzungen des menschlichen Verhaltens auf institutionelle Innovationen benötigt. Hierzu zählt das unternehmerische Verhalten im Umweltbereich. Vor diesem Hintergrund untersucht die vorliegende Arbeit, ob internetbasierte Unternehmensplanspiele geeignet sind, institutionelle Innovationen im Umweltbereich zu evaluieren. Dabei ist zunächst zu prüfen, ob Forschungsanliegen und Instrument im Einklang stehen. Ferner sind Determinanten wie Praktikabilität oder Kosten zu untersuchen.

Extra-laboratory experiments are experiments performed in environments that differ from the laboratory setting (e.g., Internet-based experiments). Internet-based experiments enable the experimenter to perform studies without spatial restrictions. One example of (Internet-based) individual experiments is given by business management games. In business management games, the experimental subjects are confronted with a real-world context, and their behavior is observed over multiple periods. In many areas of life, reliable predictions of human behavior in response to institutional innovations are required. This includes entrepreneurial adaptation processes in the environmental sector. The primary goal of the thesis is to analyze the suitability of Internet-based business management games as instruments for evaluating institutional innovations in the environmental sector. It must be examined, first, whether the research goal and the experimental design go hand in hand. Furthermore, the experimenter has to focus on determinants such as practicability and costs. However, to receive reliable forecasts of how humans behave in response to changes in their legal environment, scientists are required to replicate business management games.

description: The properties of the d-wave superconducting state in the two-dimensional system have been studied. It has been assumed, that the pairing mechanism is based on the electron-phonon and the electron-electron-phonon interactions. The obtained results have shown the energy gap amplitude ($Δ_{tot}$) crossover, from the BCS to non-BCS behavior, as the value of the electron-electron-phonon potential increases. The model has been tested for the ${\rm La_{2-x}Sr_{x}CuO_{4}}$ and ${\rm Bi_{2}Sr_{2}CaCu_{2}O_{8+δ}}$ high-$T_{C}$ superconductors. It has been shown, that the dependence of the $2Δ^{(0)}_{tot}/k_{B}T_{C}$ ratio on the hole density is in agreement with the experimental data.
title: Cyber Whistleblowers: The Black Sheep of Whistleblowing?
Creators: name: Wisniewski Jr., Andrew
Publisher: name: Old Dominion University Libraries
Year: 2022

description: From the Introduction:

Contrary to popular belief, this paper argues that cyber whistleblowing can contribute to a greater cyber security posture. However, this requires the development of clearer legal obligations and protections for cyber whistleblowers. This paper will explore the psychology behind whistleblowing, the effectiveness of whistleblowing in a cybersecurity context, how to create a safer and more transparent environment for whistleblowers and companies, and how current laws contribute to cyber whistleblowing.

description: Große Transportdienstleister (TDL) können Einsparpotentiale in der Tourenplanung durch Bündelungseffekte erschließen. Demgegenüber sind kleinere TDL auf die Bildung kooperativer Netzwerke angewiesen, um so ihre Kapazitäten auszulasten. In dieser Arbeit wird ein neuer dezentraler zweistufiger Planungsansatz vorgestellt, der die individuelle Tourenplanung der TDL mit auktionsbasierten Austausch von Transportaufträgen auf iterative Weise verbindet. Ziel ist die Gewinnmaximierung der Kooperation ohne die Schlechterstellung einzelner TDL bei geringstmöglichem Informationsaustausch. Dieser Planungsansatz erlaubt die Quantifizierung von Rationalisierungspotenzialen unabhängig vom Geschäftsfeld der TDL und vom Auktionsmechanismus. Dazu werden die Ergebnisse von drei verschiedenen Strategien verglichen, in denen die TDL nicht kooperieren, auf Basis eines dezentralen Planungsansatzes kooperieren und auf Basis eines zentralen Planungsansatzes kooperieren.

description: We present a new matrix-valued isospectral ordinary differential equation that asymptotically block-diagonalizes $n\times n$ zero-diagonal Jacobi matrices employed as its initial condition. This o.d.e.\ features a right-hand side with a nested commutator of matrices, and structurally resembles the double-bracket o.d.e.\ studied by R.W.\ Brockett in 1991. We prove that its solutions converge asymptotically, that the limit is block-diagonal, and above all, that the limit matrix is defined uniquely as follows: For $n$ even, a block-diagonal matrix containing $2\times 2$ blocks, such that the super-diagonal entries are sorted by strictly increasing absolute value. Furthermore, the off-diagonal entries in these $2\times 2$ blocks have the same sign as the respective entries in the matrix employed as initial condition. For $n$ odd, there is one additional $1\times 1$ block containing a zero that is the top left entry of the limit matrix. The results presented here extend some early work of Kac and van Moerbeke.

description: Colin Pennycuick was almost single-handedly responsible for the successful, and continuing, merger of the engineering and mathematical sciences of aerodynamics and flight mechanics with ornithology, ecology and bird flight behaviour. He developed a mathematical/aerodynamical/ecological model of bird flight that could explain and predict bird body and wing shapes and sizes, and hence flight behaviour over a broad range of length- and time-scales, for real birds. He sought to bring rigorous quantitative methods to the people, and insisted that no matter how complex and sophisticated a theoretical model may be, unless it showed some improvement and advance in its practical utility, then it was of questionable value. He similarly insisted that model predictions be testable, and that results be openly and quantifiably given. His approach was marked by two distinct characteristics: first he pioneered the use of small aircraft and powered and unpowered gliders to follow soaring and migrating birds in their natural environment, exploiting his top-level pilot skills; second, he invented, designed and built novel instrumentation for making hitherto unheard-of laboratory and field measurements. The most well-known were his tilting wind tunnels, in which birds and bats could be trained to perform steady gliding flight. His intellectually and geographically-broad range of interests and contacts led to his being a giant influence in theoretical and practical bird flight mechanics and behaviour, one that is likely to stay with us for many decades.

DNA-Rekombination im Kerngenom höherer Pflanzen

Zsfassung in engl. Sprache

description: Die Arbeit beschreibt Eigenschaften der kovalente Neuverknüpfung von DNA Molekülen in Pflanzengenomen. Dabei wurden Untersuchungen zur extrachromosomalen sowie zur intrachromosomalen homologen Rekombination durchgeführt, die zeigten, dass im Gegensatz zu Bakterien und Hefe DNA Schäden in Pflanzen meist mittels illegitimer Rekombination repariert werden. Um die Effizienz homologer Rekombination an spezifischen Stellen zu steigern, wurde mittels der hochspezifischen Restriktionsendonuklease I-SceI Doppelstrangbrüche im Pflanzengenom induziert. So konnte homologe Rekombination an der Bruchstelle um mehrere Größenordnungen erhöht werden. Bei der Reparatur des Bruches verhalten sich die beiden Enden der DNA unabhängig voneinander, d.h. ein Ende kann mit homologer und das andere mit illegitimer Rekombination repariert werden. Bei der ausschließlichen Reparatur von Brüchen mittels illegitimer Rekombination kommt es neben Deletionen überraschenderweise auch zu Insertionen von genomischen und Transgensequenzen. All diese Vorgängen können im Wesentlichen mit einem einzigen Modell, dem "Synthesis-Dependent Strand Annealing" (SDSA) Modell, erklärt werden. Obwohl das Modell das Kopieren fast jeder Sequenz (homolog oder nicht) in den Bruch erlaubt, werden "Crossovers" vermieden. So kommt es zur Tolerierung von kleineren Veränderungen an den Bruchstellen, eine grundsätzliche Destabilisierung des hochrepetitiven Pflanzengenoms wird jedoch vermieden.
description: The work describes the properties of changes in covalent DNA linkage in the plant genome. The investigations on extra- and intrachromosomal homologous recombination demonstrated that most genomic damage in plants - in contrast to bacteria and yeast - is repaired via illegitimate recombination. To increase the efficiency of homologous recombination double strand breaks (DSBs) were induced with the help of the rare cutting restriction endonuclease I-SceI at specific sites in the plant genome. Thus, homologous recombination at the break site could be increased by several orders of magnitude. During the repair reaction both ends of the break are handled independently, so that one end can be repaired via homologous and the other via illegitimate recombination. If the break is repaired exclusively via illegitimate recombination besides deletion surprisingly also insertions of genomic and transgene sequences could be detected. All processes can be described in principle by the universal "synthesis-dependent strand annealing" (SDSA) mechanism of recombination. The model explains why almost any kind of sequence can be copied via homologous or illegitimate recombination into the break, however it excludes "crossovers" between donor and acceptor locus. As a result small changes at the break site are tolerated but a global destabilisation of the highly repetitive plant genome is avoided.
Lived notions of citizenship and the human right to water in Site C, Khayelitsha, Cape Town, South Africa

description: South Africa has been undergoing significant changes over the past three decades with the dismantlement of the apartheid state, followed by a series of socio-political and economic changes. The structural transformation of the new democratic South Africa has been accompanied by many progressive developments for which the country has been widely praised - but also critiqued. Major elements of this transformation have been improving service delivery for formerly marginalized populations and redressing structural historical inequalities. The main goal of this work is to investigate how these changes affect on-the-ground realities in areas of Cape Town, South Africa, by focusing on the micro level, namely on communities and individuals in marginalized urban areas. This manuscript-based thesis is founded on Master’s research conducted in 2012, with a follow up in 2013, in Site C, Khayelitsha, a partly informal township in Cape Town, South Africa. It investigates the conditions of water access in Site C, the different meanings people attach to water access as well as associated implications for experiences of the human right to water and citizenship more broadly. Chapter 2 analyzes the ways in which the post-apartheid state is encountered in Site C through access to services, and water in particular. It traces the significance of service delivery to previously marginalized populations, such as informal settlements and black townships, as foundational in defining the relationships these populations have with the post-apartheid state. This chapter concludes that these relationships vary significantly along the lines of formality, whereby the housing formalization process contributes to the marginalization of shack dwellers. Chapter 3 focuses more specifically on the human right to water, for which South Africa has been widely praised in both academic and policy realms. This chapter adopts a “lived notions of rights” conceptualization and draws attention to the material conditions as well as the emotive and discursive meanings of water access for residents of Site C. This thesis contributes to a more nuanced understanding of the everyday lived dimensions of relative marginalization, proceeding alongside the housing formalization process in Cape Town and South Africa as a whole.
