Understanding the spatial and functional relationship between cadherins and neuroligins at synapses
Creators: name: Aiga, Mytyl
Publisher: name: University of British Columbia
Year: 2010

description: Cadherins and Neuroligins (NLs) are two of the most extensively studied cell adhesion molecules (CAMs) at synapses and have previously been shown to localize to synapses and exert a key role during their development. Despite this, their spatial and functional relationship with respect to one another has not been studied to date. In the present study, we examine the spatial and functional relationship of cadherin and NL isoforms at glutamatergic and GABAergic synapses in cultured hippocampal neurons. Analysis of the synaptic distribution of N-cadherin and NL1 and NL2 in hippocampal cultures, confirm previous studies demonstrating the enrichment of NL2 at GABAergic synapses and enrichment of NL1 and N-cadherin at glutamatergic synapses. We have also observed subsets of GABAergic synapses that express both N-cadherin and NL2 as well as glutamatergic synapses that only express either NL1 or N-cadherin. These groups of glutmatergic and GABAergic synapses may represent a specific subtype of synapse, or may reflect the differential localization of these adhesion molecules during synapse formation. Moreover, using a combination of overexpression and knockdown analysis we demonstrate that NL1 and N-cadherin promote the formation of synapses, in part, by a common pathway. Indeed, knocking down these proteins individually results in approximately 50% reduction in glutamatergic synapse density with a similar reduction upon combined knockdown. In addition, functional compensation assays demonstrate that NL1 expression can fully rescue synapse loss that is due to knockdown of N-cadherin expression. Furthermore, N-cadherin expression can partially rescue synapse loss that is due to knockdown of NL1 expression. Together this work demonstrates that these two cell adhesion proteins act in concert to regulate excitatory synapse formation. Specifically, we show that N-cadherin acts upstream of NL1 to promote synapse formation and that NL1 is a limiting factor in this pathway.

description: The Volta River Basin (VRB) in West Africa is facing water conflicts that include water quantity, water quality, pollution, flooding, and competition for water for hydroelectric power generation and water for irrigation. The VRB’s six riparian nations; Benin, Burkina Faso, Côte d'Ivoire, Ghana, Mali, and Togo, created a legal regime called the Volta Basin Authority (VBA) to address the water conflicts. However, the VBA has failed to address the water conflicts as it is plagued by deficiencies in its legal structures and policies. The International Joint Commission (IJC) on the other hand, has successfully addressed the boundary waters disputes between the United States and Canada. The IJC’s success has been aided by its exercise of its Reference Jurisdiction mandate that has allowed it to use flexibility to investigate and report on questions referred to it by the governments of the United States and Canada. This thesis seeks to identify the factors that have assisted the IJC’s successful use of flexibility under its Reference Jurisdiction mandate. It assesses the VBA as presently constituted and finds that it lacks an IJC-type independent fact-finding body that is equipped with flexible Reference Jurisdiction-type powers. The thesis suggests that incorporating an IJC-type structure with a flexible Reference Jurisdiction-type mandate into the VBA would assist the VBA to better address the water conflicts in the VRB. As well, the thesis recommends changes to the VBA’s other legal structures and policies to assist it to better deal with the water conflicts in the VRB.

description: Let (M,g) be a compact Riemannian manifold of dimension n. For k \in {0,...,n}, we denote Gr_{k}(M) the set of compact, connected and oriented submanifolds of M of dimension k. This set is called the non-linear Grassmannian. In this article, we endow Gr_{k}(M) with a smooth Fréchet manifold structure and investigate its basic geometrical properties. In particular, if Σ\in Gr_{k}(M), we show that the space of smooth embeddings Emb(Σ,M) is the total space of principal fiber bundle with base space a collection of connected components of Gr_{k}(M). We also show that the connected components of Gr_{k}(M) are homogeneous with respect to the natural action of the group of diffeomorphisms of M.

description: Sandpack model columns filled with two kinds of heavy oil were used to study the influence of nitrate injections on oil production. Columns containing trapped oil and nitrate consistently produced more oil than columns without nitrate in anaerobic conditions under counter-diffusion-induced gas drive. The presence of nitrate likely led to an increase of biomass and amounts of produced biosurfactants, allowing a reduction of oil-water interfacial tension. Gas-driven recovery of oil rich in alkanes (EO) was enhanced to a greater extent through nitrate injection than recovery of oil rich in polyaromatic hydrocarbons (LO). A water flood following incubation of columns containing nitrate did not lead to trapped oil production indicating that microbial growth was not sufficient to plug high permeability zones. Nitrate reducers Azoarcus and Delftia, the former being from the field of origin of EO, were found to consume heptane as a sole source of carbon and energy. Bioinformatics analysis of pyrosequenced 16S rDNA of the microbial communities adhering to EO and associated with an aqueous phase of a produced water-EO mixture showed that the former community was less diverse than the latter. Many known hydrocarbon degraders, e.g. Thalassolituus, Rhodococcus and Sphingomonas, were found to adhere to EO. In contrast, all identified genera of the Deltaproteobacteria were found to reside predominantly in the aqueous phase, likely because their substrates were mostly water-soluble. Consistently with the fact that hydrogen is more soluble in oil than in water, hydrogenotrophs, e.g. Methanolobus, Methanobacterium and Acetobacterium, had higher representation in the microbial community adhering to EO than in the community associated with an aqueous phase. The application of a cell-containing supernatant from the culture of a native rhamnolipid producer led to a greater enhancement of water-flood-driven LO recovery than the application of chemical surfactants. The application of cell-containing supernatants from cultures of a recombinant strain carrying genes responsible for rhamnolipid production and a strain with repressed transcription of rhamnolipid production genes led to enhancement of counter-diffusion-induced-gas-driven EO recovery, suggesting that very low surfactant concentrations are required for MEOR under solution gas drive.

description: We demonstrate with first-principles electron transport calculations that large tunneling magnetoresistance (TMR) and tunneling electroresistance (TER) effects can coexist in an all-oxide device. The TMR originates from the symmetry-driven spin filtering provided by the insulating BaTiO3 barrier to the electrons injected from SrRuO3. In contrast the TER is possible only when a thin SrTiO3 layer is intercalated at one of the SrRuO3/BaTiO3 interfaces. As the complex band-structure of SrTiO3 has the same symmetry than that of BaTiO3, the inclusion of such an intercalated layer does not negatively alter the TMR and in fact increases it. Crucially, the magnitude of the TER also scales with the thickness of the SrTiO3 layer. The SrTiO3 thickness becomes then a single control parameter for both the TMR and the TER effect. This protocol offers a practical way to the fabrication of four-state memory cells.
Mothers' experiences of an interdisciplinary team process for their child with a feeding disorder

Publisher: name: University of British Columbia
Year: 2010

description: Purpose: (1) to describe mothers’ experiences of an interdisciplinary feeding team process for their child with a feeding disorder; (2) to explore the perspectives of mothers as they implement recommendations from the feeding team. Methods: In this qualitative descriptive phenomenological study, nine mothers whose child had a complex feeding disorder and who recently went through an interdisciplinary feeding assessment participated in two semi-structured interviews. The first interview took place just after the feeding assessment, while the second was conducted a few months later. Colaizzi’s method of data analysis was used to analyze the data. Findings: Five themes emerged from the analysis. 'Taking Action' reflects the recognition and the action that was being taken by mothers to address their child’s feeding disorder. 'The Balancing Act' describes the range of experiences that mothers identified during the interdisciplinary assessment process. 'The Impact' reflects the mix of emotions that mothers experience at the conclusion of the feeding assessment, as well as the knowledge and insight gained regarding their child’s feeding. 'We Are On Our Own' represents the process of positive change that mothers go through as they implement recommendations from the team; and finally, 'We Can Now Move Forward' describes the restoration of balance in the lives of mothers as they adapt to the recommendations provided by the team. Knowledge gained from the feeding team facilitates mothers’ acceptance of their child’s feeding difficulties and helps them to look towards the future with renewed hope. The stressors that mothers’ experienced prior to the feeding assessment had an impact on their experience of the assessment. Mothers described uncertainties and anxieties prior to and during the feeding assessment. These stressors have the potential to be alleviated with increased communication with families. Implications: This study has highlighted the importance of using an interdisciplinary team to address paediatric feeding difficulties. In addition, the findings suggest that receiving knowledge helps to facilitate problem-focused coping in mothers. Understanding the broader impact of an interdisciplinary feeding team on decreasing caregiver stress is critical for further legitimizing the service and ensuring funding when the healthcare system is already strained.

description: By analysing models of the young massive cluster R136 in 30 Doradus, set-up using the herewith introduced and publicly made available code McLuster, we investigate and compare different methods for detecting and quantifying mass segregation and substructure in non-seeing limited N-body data. For this purpose we generate star cluster models with different degrees of mass segregation and fractal substructure and analyse them. We quantify mass segregation by measuring, from the projected 2d model data, the mass function slope in radial annuli, by looking for colour gradients in radial colour profiles, by measuring Allison's Lambda parameter, and by determining the local stellar surface density around each star. We find that these methods for quantifying mass segregation often produce ambiguous results. Most reliable for detecting mass segregation is the mass function slope method, whereas the colour gradient method is the least practical in an R136-like configuration. The other two methods are more sensitive to low degrees of mass segregation but are computationally much more demanding. We also discuss the effect of binaries on these measures. Moreover, we quantify substructure by looking at the projected radial stellar density profile, by comparing projected azimuthal stellar density profiles, and by determining Cartwright & Whitworth's Q parameter. We find that only high degrees of substructure affect the projected radial density profile, whereas the projected azimuthal density profile is very sensitive to substructure. The Q parameter is also sensitive to substructure but its absolute value shows a dependence on the radial density gradient of the cluster and is strongly influenced by binaries. (abridged)

description: Sprinting along a curved path is regularly performed in athletics. Yet, the locomotion mechanisms behind curved sprinting performance are relatively unexplored. The current dissertation aimed to explore the limiting factors for curved sprinting performance from a biomechanical perspective. It was discovered that the available traction between footwear and ground can limit the maximum-effort curved sprinting performance, but only to a certain extent. As available traction was systematically increased from a traction coefficient of 0.26 to 0.82, the athletes leaned more into the ground, generated a greater impulse against the ground and achieved a higher performance. Further increases in the available traction could not be utilized by the athletes for additional performance benefits. With an experimental perturbation of additional body mass, the idea that non-sagittal plane joint stabilizing moments may limit performance was examined. It was revealed that for the ankle and knee joints, non-sagittal plane moments higher than that experienced in maximum-effort curved sprints can indeed be endured. This observation challenged the stabilizing moment limit theory. When sprinting with and without the additional mass, the total ankle moment generation remained constant, despite significant differences in the ground reaction force. It is possible that the ankle moment generation is at the limit. Through an induced acceleration analysis, it was identified that moment generated at the ankle contributed to the majority of the ground force generation. It is possible that the ankle moment generation was maximized for its importance in the ground force generation. To examine the idea that ankle moment generation may limit curved sprinting performance, an experimental intervention of wedged footwear was implemented aiming to increase the ankle moment. By aligning the ankle joint closer to its neutral configuration in the frontal plane, ankle moment generation increased. That increase was associated with significant improvements in ground impulse generation, and overall curved sprinting performance.

description: Microbial populations in the natural environment are likely to experience growth conditions very different from those of a typical laboratory xperiment. In particular, removal rates of biomass and substrate are unlikely to be balanced under realistic environmental conditions. Here, we consider a single population growing on a substrate under conditions where the removal rates of substrate and biomass are not necessarily equal. For a large population, with deterministic growth dynamics, our model predicts that this system can show transient (damped) oscillations. For a small population, demographic noise causes these oscillations to be sustained indefinitely. These oscillations arise when the dynamics of changes in biomass are faster than the dynamics of the substrate, for example, due to a high microbial death rate and/or low substrate flow rates. We show that the same mechanism can produce sustained stochastic oscillations in a two-species, nutrient-cycling microbial ecosystem. Our results suggest that oscillatory population dynamics may be a common feature of small microbial populations in the natural environment, even in the absence of complex interspecies interactions.

description: Galaxies in the Universe are distributed in a web-like structure characterised by different large-scale environments: dense clusters, elongated filaments, sheetlike walls, and under-dense regions, called voids. The low density in voids is expected to affect the properties of their galaxies. Indeed, previous studies have shown that galaxies in voids are on average bluer and less massive, and have later morphologies and higher current star formation rates than galaxies in denser large-scale environments. However, it has never been observationally proved that the star formation histories (SFHs) in void galaxies are substantially different from those in filaments, walls, and clusters. Here we show that void galaxies have had, on average, slower SFHs than galaxies in denser large-scale environments. We also find two main SFH types present in all the environments: 'short-timescale' galaxies are not affected by their large-scale environment at early times but only later in their lives; 'long-timescale' galaxies have been continuously affected by their environment and stellar mass. Both types have evolved slower in voids than in filaments, walls, and clusters.

description: A detailed simulation study is performed for multi-tau-lepton signatures at the Large Hadron Collider, which can be used to probe additional Higgs bosons with lepton-specific Yukawa interactions. Such an extended Higgs sector is introduced in some of new physics models at the TeV scale. We here consider the two Higgs doublet model with the Type-X Yukawa interaction, where nonstandard Higgs bosons predominantly decay into tau leptons. These extra Higgs bosons can be pair produced via s-channel gauge boson mediation at hadron colliders; q \bar q \to Z \to HA and q \bar q' \to W^\pm \to HH^\pm (AH^\pm), where H, A and H^\pm are CP-even, odd and charged Higgs bosons, respectively. Consequently, multi-tau-lepton originated signals appear in the final state as a promising signature of such a model. We find that the main background can be considerably reduced by requiring the high multiplicity of leptons and tau-jets with appropriate kinematical cuts in the final state. Thus, assuming the integrated luminosity of a hundred of inverse fb, the excess can be seen in various three- and four-lepton channels. With the integrated luminosity of thousands of inverse fb, the determination of the mass as well as ratios of leptonic decay branching ratios of these Higgs bosons would also be possible.

title: Development of a programming library for general bioinformatics

description: Bioinformatics progresses at an unprecedented pace. At the same time the software implementing the essential algorithms is often incompatible with each other in terms of data input and output. In consequence it can require substantial effort to establish a workflow that combines different programs. Furthermore, the flexibility of such software is usually limited to a relatively small number of options. These circumstances hamper the adaption of these programs to new problems. An alternative approach to command line programs are programming libraries, that enable the user to apply already implemented algorithms and at the same time to harness the full feature spectrum of a programming language. In this thesis the Python bioinformatics package Biotite is presented. It unifies popular algorithms from sequence and structure analysis into a flexible library, which is applicable to a wide range of biological questions. Furthermore, new algorithms are presented, enhancing the bioinformatician’s toolkit with a novel sequence alignment visualization approach and universally applicable hydrogen prediction method. Finally, via the application of Biotite this thesis provides new insights into the molecular mechanism of cation channels and novel evaluation methods for sequencing data from SELEX experiments.

description: JWST observations, when combined with HST data, promise to improve age estimates of star clusters in nearby spiral galaxies. However, feedback from young cluster stars pushes out the natal gas and dust, making cluster formation and evolution a challenge to model. Here, we use JWST + HST observations of the nearby spiral galaxy NGC 628 to produce spectral energy distribution (SED) templates of compact star clusters spanning 275 nm through 21 μm. These preliminary SEDs capture the cluster stars and associated gas and dust within radii of 0.12" to 0.67" (corresponding to 6 to 33 pc at the distance of NGC 628). One important finding is that the SEDs of 1, 2, 3, and 4 Myr clusters can be differentiated in the infrared. Another is that in 80-90% of the cases we study, the PAH and H_alpha emission track one another, with the dust responsible for the 3.3 μm PAH emission largely removed by 4 Myr, consistent with pre-supernova stellar feedback acting quickly on the surrounding gas and dust. Nearly-embedded cluster candidates have infrared SEDs which are quite similar to optically visible 1 to 3 Myr clusters. In nearly all cases we find there is a young star cluster within a few tenths of an arcsec (10 - 30 pc) of the nearly embedded cluster, suggesting the formation of the cluster was triggered by its presence. The resulting age estimates from the empirical templates are compatible both with dynamical estimates based on CO superbubble expansion velocities, and the TODDLERS models which track spherical evolution of homogeneous gas clouds around young stellar clusters.

description: In the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), Asperger Syndrome (AS) has been eliminated and integrated into a new Autism Spectrum Disorder (ASD) diagnostic framework. The loss of AS has social implications for people who self-identify and derive personal meaning from their diagnosis. The current study explored the opinions of adults with AS regarding the identity terms related to the changing classification of ASD. A qualitative approach was adopted whereby 12 participants each completed a semi-structured interview that was transcribed and analyzed via Thematic Analysis. The data revealed six themes: 1) Derived Meaning, 2) Knowledge and Understanding, 3) Perceptions and labels, 4) Social Identity, 5) Opinions and Reactions to ASD, and 6) Barriers to Funding and Service Provision. Overall, the results from the current study have practical utility for the AS community, families, and professionals, and will form the basis of future research.

description: The Square Kilometre Array and its pathfinders ASKAP and MeerKAT will produce prodigious amounts of data that necessitate automated source finding. The performance of automated source finders can be improved by pre-processing a dataset. In preparation for the WALLABY and DINGO surveys, we have used a test HI datacube constructed from actual Westerbork Telescope noise and WHISP HI galaxies to test the real world improvement of linear smoothing, the {\sc Duchamp} source finder's wavelet de-noising, iterative median smoothing and mathematical morphology subtraction, on intensity threshold source finding of spectral line datasets. To compare these pre-processing methods we have generated completeness-reliability performance curves for each method and a range of input parameters. We find that iterative median smoothing produces the best source finding results for ASKAP HI spectral line observations, but wavelet de-noising is a safer pre-processing technique. In this paper we also present our implementations of iterative median smoothing and mathematical morphology subtraction.

description: Alberta’s publicly funded university business schools operate within environments that are challenging and changing. Specifically, Alberta has historically been a significant contributor to Canada’s economy, driven by the energy sector. Recently, low oil prices and geopolitical uncertainties have created a recessionary environment. This boom-bust economy, along with Alberta’s reputation as an entrepreneurial heartland, provide a unique landscape for university business schools that are contending with increased competition, pressures to maintain quality programming, and the need to secure sustainable funding. This research explored the rationale and extent to which publicly funded Alberta university business schools exhibit an entrepreneurial presence. The study sought to understand: (1) the entrepreneurial strategies pursued by Alberta public university business schools; (2) the reasons why entrepreneurialism is a part of the business school strategic plan; (3) how entrepreneurial success is being achieved; and (4) barriers to entrepreneurial success. The outcome of the study was an entrepreneurial business school roadmap model. A sequential mixed methods research design was followed. Phase I consisted of semi-structured interviews with 12 Alberta university business school leaders at two sites. The results of Phase 1 informed the development of an electronic survey that was deployed in Phase 2 to business school leaders and faculty at five publicly funded Alberta university business schools. The results of Phase 1 and 2 were then combined. The core theme that emerged was that “business schools are at the centre of an entrepreneurial ecosystem engaging through entrepreneurship oriented centres, executive education, and pedagogical innovations as a key driver of the institutional entrepreneurial effort.” The evidence suggested that business school entrepreneurial activity occurs in two areas: a) entrepreneurship centres, and b) executive education. Eight clusters comprise the Alberta business school entrepreneurial ecosystem and these clusters became the supporting foundation of the entrepreneurial business school roadmap model. This model depicts the business school playing a central role in extending entrepreneurial activities within the university. The entrepreneurial business school roadmap model may interest policy-makers, leaders, and faculty who develop strategy for business schools. It illustrates the relationship between opportunities, drivers, and outcomes within the entrepreneurial ecosystem using a business school extension approach.

description: Between the late 1960s and mid-1990s, American ground forces employed the Vulcan Air Defence System (VADS), for use against short range, aerial and ground targets. The VADS was mobile and comprised a radar and a six barrelled 20 mm autocannon, but this was soon found to be ineffective against fast aircraft at low altitudes. Despite being an old technology by 1982 an Israeli VADS downed a fighter jet and this is believed to be the only time in VADS operational history. This happened during the 1982 Israel – Lebanon war in the midst of intense ground combat and where the VADS helped unexpectedly. That event, the VADS withdrawal from operations in the 1990s, and their recent reappearance in use against drones are discussed.

description: When an immiscible oil drop is immersed in a stably stratified ethanol-water mixture, the Marangoni flow on the surface of the drop can experience an oscillatory instability, so that the drop undergoes a transition from levitating to bouncing. The onset of the instability and its mechanisms have been studied previously, yet the bouncing motion of the drop itself, which is a completely different problem, has not yet been investigated. Here we study how the bouncing characteristics (jumping height, rising and sinking time) depend on the control parameters (drop radius, stratification strength, drop viscosity). We first record experimentally the bouncing trajectories of drops of different viscosities in different stratifications. Then a simplified dynamical analysis is performed to get the scaling relations of the jumping height and the rising and sinking times. The rising and sinking time scales are found to depend on the drag coefficient of the drop $C_D^S$ in the stratified liquid, which is determined empirically for the current parameter space. For low viscosity (5 cSt) oil drops the results on the drag coefficient match the ones from the literature. For high viscosity (100 cSt) oil drops the parameter space had not been explored and the drag coefficients are not readily available. Numerical simulations are therefore performed to provide external verification for the drag coefficients, which well match with the experimental results.

description: Monopis neglecta Šumpich & Liška, 2011
Diese zu den Echten Motten zählende Art wurde erst vor wenigen Jahren erkannt und im Jahr 2011 beschrieben (ŠUMPICH 2011). Eine Überprüfung weiterer Belege aus den Aufsammlungen der letzten Jahre durch den Tineidae-Spezialisten Dr. R. Gaedike aus Leibnitz bestätigte die Art erstmals für Kärnten. Der Falter wurde im Rahmen eines kleinen Naturschutzprojektes in Kooperation mit der Arge NATURSCHUTZ im Bereich der Ortschaft Eberstein am sogenannten “Kirchfelsen” belegt.
Funddaten: Eberstein-Kirchfelsen 21.8.2012; leg. Wieser, det. Gaedike.
Aus Österreich ist M. neglecta lt. HUEMER 2013 aus Niederösterreich und Wien (unpubl.) bekannt.

Winning Conditions for Charter Reconsideration: Assisted Suicide and the Supreme Court of Canada

description: In February 2015, the Supreme Court struck down Canada’s prohibition of physician-assisted suicide (PAS). Not only did the Carter decisions mark a historic point in the long fight to legalize PAS in Canada, but it was also the second Supreme Court case in a little over a year to revisit, and depart from, an earlier Charter precedent. Stare decisis, or precedent, is a fundamental doctrine of the legal system that judges are reluctant to ignore. However, in Bedford, the Supreme Court outlined new criteria for revisiting a precedential decision, and these same criteria allowed for the success of Carter fourteen months later. The Supreme Court is taking a new approach to stare decisis, and this thesis used the PAS movement and Carter as a case study to explore the winning conditions for precedent reversal.
The VERITAS Extragalactic non-Blazar Program
Creators: name: Galante, Nicola
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: VERITAS is an array of four 12-m diameter imaging atmospheric-Cherenkov telescopes located in southern Arizona. Its aim is to study the very high energy (VHE: E > 100 GeV) gamma-ray emission from astrophysical objects. In addition to the study of blazars, the VERITAS extragalactic science program develops a comprehensive observational program of extragalactic non-blazar sources. The study of Active Galactic Nuclei (AGN) is intensively pursued through the large MWL observational campaign on non-blazar radio galaxies. The success of these MWL campaigns has for the first time provided insights to the inner structures of jets responsible for gamma-ray emission. The problem of the origin and acceleration of ultra-high energy cosmic rays is pursued through the observation of the starburst galaxy M 82, whose detection at VHE delivers important insights on the possible acceleration mechanisms. Finally, investigation of globular clusters places important limits on the millisecond pulsar contribution to their addressed gamma-ray emission. The VERITAS extragalactic non-blazar science program and its results are presented.

Keeping the Occupiers Occupied: Leisure and Tourism in the British Rhine Army, 1918-1929
Creators: name: Williams, Tom
Publisher: name: British Journal for Military History
Year: 2023

description: After the ordeals of the First World War, the military occupation of the Rhineland offered members of the British Army unprecedented opportunities for travel and amusement. Posted to a region popular with British tourists before 1914, the British occupiers were encouraged, particularly by the English-language Cologne Post, to make the most of their time on the ‘Romantic Rhine’, even though the Army wished to limit their interactions with the German population. This article examines how travel and tourism, and particularly walking excursions, were promoted in the Rhine Army as healthy, educational alternatives to the perceived dangers of fraternisation and especially of city life in Cologne.

description: Theoretical and observational challenges to standard cosmology such as the cosmological constant problem and tensions between cosmological model parameters inferred from different observations motivate the development and search of new physics. A less radical approach to venturing beyond the standard model is the simple mathematical reformulation of our theoretical frameworks underlying it. While leaving physical measurements unaffected, this can offer a reinterpretation and even solutions of these problems. In this spirit, metric transformations are performed here that cast our Universe into different geometries. Of particular interest thereby is the formulation of cosmology in Minkowski space. Rather than an expansion of space, spatial curvature, and small-scale inhomogeneities and anisotropies, this frame exhibits a variation of mass, length and time scales across spacetime. Alternatively, this may be interpreted as an evolution of fundamental constants. As applications of this reframed cosmological picture, the naturalness of the cosmological constant is reinspected and promising candidates of geometric origin are explored for dark matter, dark energy, inflation and baryogenesis. An immediate observation thereby is the apparent absence of the cosmological constant problem in the Minkowski frame. The formalism is also applied to identify new observable signatures of conformal inhomogeneities, which have been proposed as simultaneous solution of the observational tensions in the Hubble constant, the amplitude of matter fluctuations, and the gravitational lensing amplitude of cosmic microwave background anisotropies. These are found to enhance redshifts to distant galaxy clusters and introduce a mass bias with cluster masses inferred from gravitational lensing exceeding those inferred kinematically or dynamically.

Managing the Medicalization of Madness: A Narrative Analysis of Personal Stories about Mental Illness Online

description: Emancipatory in spirit this thesis asserts personal narratives are an essential and active contributor to the development of meanings in discourse about mental illness and they have an influential role managing medicalization. The medicalization of madness is increasingly contested as people describe and explain how medical approaches and definitions of mental illness at best fail to adequately account for personal experiences of distress, and at worst are the cause of increased physical and psychological trauma. This thesis examines personal narratives posted publicly on medical, social care, and activist websites by organizations and individuals offering support and information about mental illness, community care options, psychiatric survivorship, activism and advocacy. Initial reviews indicated personal stories are included on websites by organizations and individuals with differing views, either for or against medical approaches, suggesting narratives are valued as a way to support or challenge various perspectives on medical approaches to mental illness. In this thesis the objective is not to determine which view is correct or truthful, rather it is to examine how people manage discourse about mental illness as it relates to their personal experiences, whether they identify as health care consumers, patients, ex-patients, or psychiatric survivors. Drawing on Habermas’s (1987) Theory of Communicative Action and Fairclough’s (1992) Social Theory of Discourse this thesis conceptualizes personal narratives as discursive practices and active sites where meaning is negotiated as people work to express lifeworld experiences in ways that fit with, yet challenge system discourses about mental illness. Using Gubrium and Holstein’s (2009) methodology of Narrative Ethnography the analysis identifies and examines personal stories about what it’s like being a patient, how social relationships matter, and why recovery is personal. The analysis shows people manage medicalization of their experiences in their stories by making meaningful connections between personal experiences and discourse about mental illness via a narrative practice (introduced here) called narrative bridging. To accomplish this people use narrative strategies of resisting, re-informing, and reinforcing discourse about mental illness, and it is through these strategies and the consequences of narrative bridging that medicalization is managed in personal narratives.
