description: A significant challenge in estimating operational feasibility of Urban Air Mobility (UAM) missions lies in understanding how choices in design impact the performance of a complex system-of-systems. This work examines the ability of the UAM ecosystem and the operations within it to meet a variety of demand profiles that may emerge in the coming years. We perform a set of simulation driven feasibility and scalability analyses based on UAM operational models with the goal of estimating capacity and throughput for a given set of parameters that represent an operational UAM ecosystem. UAM ecosystem design guidelines, vehicle constraints, and effective operational policies can be drawn from our analysis. Results show that, while critical for enabling UAM, the performance of the UAM ecosystem is robust to variations in ground infrastructure and fleet design decisions, while being sensitive to decisions for fleet and traffic management policies. We show that so long as the ecosystem design parameters for ground infrastructure and fleet design fall within a sensible range, the performance of the UAM ecosystem is affected by the policies used to manage the UAM traffic.
Theoretical issues in Nuu-Chah-Nulth phonology and morphology
Creators: name: Kim, Ŭn-Suk
Publisher: name: University of British Columbia
Year: 2009

description: The goals of the dissertation are documentation and description of the language, and investigation of theoretical issues raised by the language data. Nuu-chah-nulth, which constitutes, along with Ditidaht and Makah, the Southern branch of the Wakashan family, is in immediate danger of extinction. There are many factors contributing to endangerment, but above all, there is an enormous generation-gap between people who can speak the language and people who cannot, which may ultimately be too deep and broad to bridge without significant linguistic or educational measures. The problem is compounded by the fact the there is very little documentation of the language, hampering both linguistic research and efforts in the realm of education/revitalisation of the language. This work will contribute to documentation of Nuu-chah-nulth, which will ultimately help Nuu-chah-nulth people to develop education materials for their children. Although previous studies describe and analyse Tseshaht and Kyuquot, two of the 12 Nuu-chah-nulth dialects, there is not much comprehensive work where both the Nuu-chah-nulth sound system and related phonological phenomena and its morphology, are both well-described and analysed. Nuu-chah-nulth has unique and interesting dialect variation as well as linguistic phenomena which require organisation and generalisation. This thesis focuses on the description of the Ahousaht dialect. The documentation, in conjunction with previous work, will help us understand Nuu-chah-nulth better in terms of the different evolution between dialects as well as both linguistic and typological characteristics of the language. It is important to investigate the phonology and morphology of Nuu-chah-nulth from the perspective of linguistic theory. Many phonological and morphological processes in Nuu-chah-nulth raise interesting questions in terms of universality, markedness, learnability, variability, and typological issues. Theoretical treatments of linguistic phenomena will help us understand the language itself better, and general characteristics of human language as well. I discuss the segmental phonology of the language in Chapter 3, including the treatment of pervasive phonological processes such as glottalisation, lenition, (de)labialisation, vowel lengthening, vowel shortening, and vowel alternation due to variable vowels; I treat prosodic phonology in Chapter 4, the morphological structure of words in Chapter 2, and morphological processes such as reduplication and allomorphy in Chapter 5. I treat these phenomena within Optimality Theory, due to its direct encoding of claims concerning universality, language variation, and typology.

description: Japanese aesthetics in food and advertising have emerged as a huge worldwide consumer phenomenon. Marketers in Japan and some Asian regions embrace visual and emotional appeals of Kawaii (cute) food advertising to capture consumer interest and raise their purchase intentions. This dissertation used the attitude toward the ad and purchase intention as a proxy to investigate the Bahraini community's acceptance of Japanese aesthetics in food marketing, specifically, Kawaii advertising. A quantitative research methodology was undertaken to examine the influence of Japanese food aesthetics such as the sensory appeal, food authenticity, nutritional quality, and Kawaii appeal on Bahraini society's purchase intentions as well as their attitude towards the food in the Kawaii advert. An online survey was administered to Bahraini respondents. The findings revealed that sensory and Kawaii appeal was positively appraised from the perspective of Bahraini consumers, resulting in a favorable attitude and buying intention toward Japanese food.

description: Motivated by the recent measurement of the upper limit of ${B}^0 \to J/ψD$ branching ratio, which is important in accounting for the soft $J/ψ$ production in B decays, we investigate ${B}^0 \to J/ψD^{(\star)}$ and $η_c D^{(\star)}$ decays in perturbative QCD approach based on $k_T$ factorization. Being pure annihilation (W-exchange) decays, these branching ratios are estimated to be at the order of $10^{-5} \sim 10^{-7}$, which are just at the corner of being observable at the $B$ factories. The measurements of these decay channels may help us to understand the QCD dynamics in the corresponding energy scale, especially the reliability of pQCD approach to these processes.

description: When assessing climate change impact, adaptation is an important behavioral response to reduce potential risk. But it has been widely recognized that there are barriers to adaptation. And attempts to estimate impacts may be biased when these barriers neglected. Potential barrier on adaptation decision from market structure have not been identified. We develop a theoretical model to evaluate adaptation incentives of farmers under climate change across various market structures. In agricultural production where acreage adjustment is costly, our theoretical model suggests that the “competition effect” plays an important role in determining incentives to adapt. The competition effect in the market may outweigh the production effect and reduce producer incentives to change production practices. Results also suggest that monopolists may have a higher incentive to adapt since the market is under their direct control with less competition even though these incentives are still much smaller than socially optimal levels. In contrast, there can be strategic interactions among players which can lead to inaction (not investing in adaptations) due to the threat of potentially higher competition in other market structures.

description: Structure and stability of 3 nm size Ag$_{887}$, Au$_{887}$ and Ti$_{787}$ clusters deposited on graphite under soft-landing conditions ($\sim 10^{-3}- 10^0$ eV per atom) are studied by means of molecular dynamics simulations. Parameters for the cluster-surface interaction are derived from complementary ab initio calculations. We found that the shape of clusters on the surface is governed by their elemental composition and depends also on the initial cluster structure and landing conditions. At deposition energies below 0.1 eV/atom, the Ag$_{887}$ cluster acquires an ellipsoidal shape, while Au$_{887}$ and Ti$_{787}$ clusters transform into oblate and prolate truncated spheroids, respectively, due to stronger adhesion to graphite. The clusters flatten over the surface and eventually disintegrate as the deposition energy increases. Simulation results reveal that Ag$_{887}$ and Au$_{887}$ fragment at about $0.75 - 1.0$ eV/atom whereas higher energy of about 3 eV/atom is required for the fragmentation of Ti$_{787}$. The contact angle, contact radius and height of the clusters as functions of deposition energy are determined from fitting the positions of cluster surface atoms with a surface equation. The dependence of these parameters on the internal energy of the clusters is also analyzed.

description: As a result of substantial government support, Norway is more or less self-sufficient in its main agricultural products. This contributes to both trade distortions and higher greenhouse gas (GHG) emissions. In multinational negotiations separate efforts are being made to liberalize trade (through the World Trade Organization) and to reduce global GHG emissions (through the United Nations). Using a model of Norwegian agriculture, we explore interconnections between trade liberalization and GHG emission reductions. We show that the Doha proposals would involve no major cut in either agricultural production or GHG emissions due to weakness in the disciplines on trade distorting support. We contrast further trade liberalization and the use of a carbon tax to achieve emission reductions. Trade liberalization involves relatively large impacts on agricultural activity. Trade distortions decrease, and, economic welfare increases substantially due to lower production. For a high cost country like Norway, this indicates that the GHG abatement cost is negative in the sector if no value is attributed to agricultural activity beyond the world market price of food. A more targeted policy to reduce GHG emissions is to use a carbon tax. Compared to the trade liberalization case, both production and land use can be kept at a higher level with only a modest decrease in economic welfare. The side-effect is, however, higher trade distortions.

description: Leakage in the fuel market differs, depending on whether ethanol production is determined by a tax credit or consumption mandate. Two components of market leakage are distinguished: domestic and international. Leakage with both a tax credit and a consumption mandate depends on market elasticities and consumption/production shares, with the former having a bigger impact. Leakage is also more sensitive to changes in market supply and demand elasticities in the country not introducing biofuels. Although positive with a tax credit, market leakage can be negative with a consumption mandate, meaning that one gallon of ethanol can replace more than a gallon of gasoline. We also show that being a small country biofuels producer does not necessarily mean that leakage for this country is 100 percent. Our numerical estimates show that one gallon of ethanol replaces approximately 0.2-0.3 gallons of gasoline in the U.S.

description: Many experiments are being planned to measure the neutrino mixing parameter $θ_{13}$ using reactor as well as accelerator neutrino beams. In this note, the theoretical significance of a high precision measurement of this parameter is discussed. It is emphasized that it will provide crucial information about different ways to understand the origin of large atmospheric neutrino mixing and move us closer towards determining the neutrino mass matrix. For instance if exact $μ\leftrightarrow τ$ symmetry in the neutrino mass matrix is assumed to be the reason for maximal $ν_μ-ν_τ$ mixing, one gets $θ_{13}=0$. Whether $θ_{13}\simeq \sqrt{Δm^2_{\odot}/Δm^2_A}$ or $θ_{13}\simeq Δm^2_{\odot}/Δm^2_A$ can provide information about the way the $μ\leftrightarrow τ$ symmetry breaking manifests in the case of normal hierarchy. We also discuss the same question for inverted hierarchy as well as possible gauge theories with this symmetry.

Studying Shôjo Manga : global education, narratives of self and the pathologization of the feminine
Creators: name: Spies, Alwyn
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation takes an interdisciplinary Cultural Studies approach to the study of shojo manga, or Japanese comics for girls and young women. Audience research is combined with textual analysis in order to explore roles for Japanese Studies in a global context. Building on the large body of Western academic writing on romance narratives and popular culture for girls (Radway 1984, McRobbie 1994, Ang 1996, Driscoll 2002) original ethnographic interviews with shojo manga readers are linked to close readings of major works by three key artists whose manga are marketed to female readers in Japan - Yoshida Akimi, Haruno Nanae, and Okazaki Kyoko. Various layers of "narratives of self" are identified within the shojo manga texts as well as within the ethnographic accounts in the dissertation and academic writing about shojo manga in general. Personal narratives are utilized to illustrate how the author's own academic writing (and this dissertation) form yet another layer of self-narrative. Connections are then made between these layers and the pathologization of the feminine; the manner in which feminist academics often construct a mature, active or independent identity in opposition to the silly complicit or passive girls clearly parallels the manner in which "the West" constructs its identity in opposition to a feminized "Orient". This then leads to the conclusion that studies of shojo manga and Japanese popular culture could be used for anti-racist and anti-sexist education - a key component of education for global citizenship.

description: We present here preliminary results of an integrated modelling approach combining a crop model (STICS) and an economic model (AROPAj) of European agricultural supply. This modelling framework is designed to perform quantitative analysis, regarding climate change impacts on agriculture and more generally the interactions between soils, land use, agriculture and climate integrating physical and economical elements (data, process, models). It explicitly integrates an agricultural diversity dimension with regards to economic set of choices and soil climate spatial variability. First results are given in term of quantitative analysis combining optimal land allocation (economic optimality) and “dose-response” functions related to a large set of crops in Europe, at the farm group level, covering part of the European Union (EU15). They indicate that accounting for economical and spatial variability may impact both regional aggregated scales results.

description: We study the baryon mass fraction in a set of hydrodynamical simulations of galaxy clusters performed using the Tree+SPH code GADGET-2. We investigate the dependence of the baryon fraction upon the radiative cooling, star formation, feedback through galactic winds, conduction and redshift. Both the cold stellar component and the hot X-ray emitting gas have narrow distributions that, at large cluster-centric distances r>R500, are nearly independent of the physics included in the simulations. Only the non-radiative runs reproduce the gas fraction inferred from observations of the inner regions (r ~ R2500) of massive clusters. When cooling is turned on, the excess star formation is mitigated by the action of galactic winds, but yet not by the amount required by observational data. The baryon fraction within a fixed overdensity increases slightly with redshift, independent of the physical processes involved in the accumulation of baryons in the cluster potential well. In runs with cooling and feedback, the increase in baryons is associated with a larger stellar mass fraction that arises at high redshift as a consequence of more efficient gas cooling. For the same reason, the gas fraction appears less concentrated at higher redshift. We discuss the possible cosmological implications of our results and find that two assumptions generally adopted, (1) mean value of Yb = fb / (Omega_b/Omega_m) not evolving with redshift, and (2) a fixed ratio between f_star and f_gas independent of radius and redshift, might not be valid. In the estimate of the cosmic matter density parameter, this implies some systematic effects of the order of Delta Omega_m/Omega_m < +0.15 for non-radiative runs and Delta Omega_m/Omega_m ~ +0.05 and < -0.05 for radiative simulations.

description: Im gesellschaftlichen Diskurs um das Stillen ist gegenwärtig, trotz fundierter sozialwissenschaftlicher Kritik, immer noch die Position als hegemonial zu bezeichnen, die das Stillen als die beste Form der Säuglingsernährung sieht. Um die Hintergründe für die Macht dieser Position besser verstehen zu können, befragt der Aufsatz medizinische Publikationen aus über einem Jahrhundert aus der wissenschaftstheoretischen Perspektive der französischen Epistemologie und zeichnet die sich darin zeigende Wissensordnung um das Stillen nach: Wie hat sich das Stillen als wissenschaftlicher Gegenstand infolge der Verwissenschaftlichung der Medizin konstituiert? Wie wurde er im Kontext moderner Dichotomien zwischen dem Natürlichen und dem Sozialen positioniert? Welche Hierarchien wurden damit bedient, stabilisiert oder unterlaufen? Zentral für die Argumentation sind drei Erkenntnishindernisse im Sinne Gaston Bachelards, die im Untersuchungszeitraum des 19. Jahrhunderts eine Verschiebung des Gegenstands Stillen von einer natürlichen zu einer „natürlich sozialen Tatsache“ erschwerten: die Hybridität der Medizin als Disziplin, die kumulative Praxis der medizinischen Forschung und ihr Fokus auf die Mutter-Kind-Dyade.

Our model is based on a simple three channel system that reproduces more elaborate coupled-channel calculations. We stress the main differences between s-wave and p-wave scattering. We show in particular that, for elastic and inelastic scattering close to a p-wave Feshbach resonance, resonant processes dominate over the low-energy behaviour.

description: How can we estimate the negative externalities of agriculture at the national level, and attribute these to specific production activities and outputs? The paper presents a method that calculates the mass flow in the whole agricultural sector including inputs from other sectors, and that allows to analyse resource use and emissions, e.g. of greenhouse gases. Data inputs are the German economic accounts for agriculture, farm structural survey and market statistics, as well as environmental statistics. In the framework of the German agricultural sector model RAUMIS, material flows within the agricultural sector are described, as well as inputs from other German sectors and imports. Through a processanalytical approach, all information is integrated and matrices of resource use and emissions for all agricultural production activities are generated. A monetary allocation is used to identify the respective activities that are responsible for emissions, including indirect emissions in upstream sectors. Related to the market output, cumulative emissions per unit of output can be computed. Results for the period from 1995 to 2007 show the trend of resource uses and emissions for the national average values of important commodities such as milk and meat.

description: Stokes inversion codes are crucial in returning properties of the solar atmosphere, such as temperature and magnetic field strength. However, the success of such algorithms to return reliable values can be hindered by the presence of oscillatory phenomena within magnetic wave guides. Returning accurate parameters is crucial to both magnetohydrodynamics studies and solar physics in general. Here, we employ a simulation featuring propagating MHD waves within a flux tube with a known driver and atmospheric parameters. We invert the Stokes profiles for the 6301 $\unicode{0xc5}$ and 6302 $\unicode{0xc5}$ line pair emergent from the simulations using the well-known Stokes Inversions from Response functions (SIR) code to see if the atmospheric parameters can be returned for typical spatial resolutions at ground-based observatories. The inversions return synthetic spectra comparable to the original input spectra, even with asymmetries introduced in the spectra from wave propagation in the atmosphere. The output models from the inversions match closely to the simulations in temperature, line-of-sight magnetic field and line-of-sight velocity within typical formation heights of the inverted lines. Deviations from the simulations are seen away from these height regions. The inversion results are less accurate during passage of the waves within the line formation region. The original wave period could be recovered from the atmosphere output by the inversions, with empirical mode decomposition performing better than the wavelet approach in this task.

description: Ziel des Beitrags ist, am Beispiel der Geschichte des Mobilitätsdiskurses das Gendering industrieller Massenprodukte im Fahrzeugbereich sowie dessen historische und gesellschaftliche Ausprägungen exemplarisch nachvollziehbar zu machen. Ausgangspunkt ist eine Definition von Design, die dessen diskursive Funktion fokussiert: Design selbst produziert Bedeutung und transportiert diese nicht nur. Vor diesem Hintergrund erfolgt ein diskursanalytischer Blick auf ‚Gendered Mobility‘ – vom historischen Geschlechterkampf ums Fahrrad bis zu Entwürfen von ‚Frauenautos‘ in der jüngeren Vergangenheit. Mittels einer solchen Analyse des gegenderten Mobilitätsdiskurses wird gezeigt, wie Design sowohl auf der Seite der Gestaltenden als auch auf der Seite der Konsumierenden an der performativen Herstellung von Geschlechtsidentität(en) und damit auch an der (Re-)Produktion der bestehenden, hierarchischen Geschlechterverhältnisse in der gegenwärtigen Wachstumsökonomie beteiligt ist – ein Vorgehen, das nicht auf Gender begrenzt ist, sondern auf weitere Diversitätsdimensionen und deren Intersektionen ausgeweitet werden kann.

Fits of these data using R-matrix theory yield a value for the S-factor at zero energy of 1.64(17) keV b, which is significantly smaller than the result of a previous direct measurement. The corresponding reduction in the stellar reaction rate for 14N(p,g)15O has a number of interesting consequences, including an impact on estimates for the age of the Galaxy derived from globular clusters.

description: 35 diamondiferous xenoliths from the Komsomolskaya and Yubileynaya pipes of Yakutia comprise bimineralic eclogites, predominantly of Group B, rare kyanite eclogites and some garnet megacrysts. Most xenoliths contain two or more diamond crystals (0.5-8.0 mm), predominantly with octahedral or transitional forms. Finegrained interstitial metasomatic mineral assemblages and partial-melting phases occur in most specimens. Clinopyroxene-garnet thermobarometry suggests equilibration at 1000–1225 °C, at pressures of 4-5 GPa and integrated residence temperatures of ~1160-1200 ºC for diamond growth. Garnets in eclogites from the Komsomolskaya pipe generally have Mg# >60 and convex-upward REE profiles. Most clinopyroxenes and some garnets in xenoliths from both pipes display LREE and MREE enrichments consistent with minor amounts of cryptic metasomatism. FTIR-data display wide variation in total nitrogen content and aggregation state in the diamonds of xenoliths from both pipes. About 80% of the crystals from Yubileynaya xenoliths have high total contents of nitrogen (600-1500 at. ppm) but low aggregation state (20-30%), while 20% of the crystals have total nitrogen contents < 500 at. ppm with high aggregation state (30-80%). Crystals in Komsomolskaya xenoliths have moderate nitrogen contents (200-900 at. ppm) and predominantly 20-50% aggregation. Diamonds with different nitrogen aggregation states occur within individual xenoliths from both pipes. The distribution of diamonds in the xenoliths, and the presence of diamonds with different nitrogen aggregation characteristics in the same xenolith, suggest multistage growth of diamond from metasomatic fluids. These data are consistent with observations on diamondiferous eclogites from other Yakutian kimberlites. Correlations between diamond grade and the relative abundance of metasomatised eclogite xenoliths and garnets indicate that the overall grade of these kimberlites is strongly controlled by the abundance or absence of eclogitic horizons in the deeper parts of the lithospheric mantle.

description: Analogies between the dynamics of pedestrian crowds and granular media have long been hinted at.They seem all the more promising as the crowd is (very) dense, in which case the mechanical constraints prohibiting overlapsmight prevail over the decisional component of pedestrian dynamics. These analogies and their origins are probed in two distinct settings, (i) a flow through a narrow bottleneck and (ii) crossing of a static assembly by an intruder. Several quantitative similarities have been reported for the former setting and are discussed here, while setting (ii) reveals discrepancies in the response pattern, which areascribed to the pedestrians' ability to perceive, anticipate and self-propel.

description: Die vorliegende explorative Studie widmet sich dem Wahlverhalten von LGBTIQ-Personen im Kontext der Abgeordnetenhauswahl in Berlin (2016) und der Gemeinderatswahl in Wien (2015). Untersucht wird erstens die queer-politische Agenda der Parteien und zweitens das Wahlverhalten von LGBTIQ, einer bislang in der Wahlforschung weitestgehend ignorierten Bevölkerungsgruppe. Der Vergleich der untersuchten Wahlprogramme zeigt, dass queer-politische Themen Marker für Differenz und Konkurrenz im Parteienwettbewerb darstellen. Die Ergebnisse der Onlinebefragung zeigen, dass die Methode eines selbstselektiven Samples geeignet ist, um die politischen Präferenzen von LGBTIQ-Personen zu untersuchen. Die Parteipräferenz für grüne Parteien ist sowohl in Berlin als auch in Wien ausgeprägt. Jenseits dessen gibt es indes in Berlin wie auch in Wien LGBTIQ-Personen, die rechtspopulistische Parteien und Positionen unterstützen.

description: We solve the mean-field $ϕ^4$ model in an external magnetic field in the microcanonical ensemble using two different methods. The first one is based on Rugh's microcanonical formalism and leads to express macroscopic observables, such as temperature, specific heat, magnetization and susceptibility, as time averages of convenient functions of the phase-space. The approach is applicable for any finite number of particles $N$. The second method uses large deviation techniques and allows us to derive explicit expressions for microcanonical entropy and for macroscopic observables in the $N \to\infty$ limit. Assuming ergodicity, we evaluate time averages in molecular dynamics simulations and, using Rugh's approach, we determine the value of macroscopic observables at finite $N$. These averages are affected by a slow time evolution, often observed in systems with long-range interactions. We then show how the finite $N$ time averages of macroscopic observables converge to their corresponding $N\to\infty$ values as $N$ is increased. As expected, finite size effects scale as $N^{-1}$.

Mother’s resistance to the Western dominant discourse on mothering
Creators: name: Horwitz, Erika
Publisher: name: University of British Columbia
Year: 2009

description: This qualitative study was undertaken for the purpose of answering the following two research questions: (a) What is the personal meaning and experience of mothering for women who feel they are actively resisting the Western dominant discourse on mothering?, and (b) How are these personal meanings and experiences grounded in the participants' personal contexts as well as in dominant and alternative discourses and discursive practices? Fifteen women ranging in age from 23 to 46 years, who self identified as actively resisting the dominant discourse, were interviewed about their mothering experiences. Their interviews were transcribed and analyzed following a critical interpretive approach (Cushman, 1995; Packer & Addison, 1989). In answering the first research question three themes were identified: (a) resisting is rewarding and liberating, (b) resisting entails juggling and balancing, (c) resisting entails cognitive work, refraining, and reconciling. Although acknowledging the pragmatic and cognitive challenges inherent in so doing, the women in the study experienced a sense of empowerment and pride in their choice to resist. In answering the second question, participants' identified concrete structural barriers to their efforts to mother differently and acknowledged the importance of supportive partners, friends, extended family members, education, financial resources, and flexible employment as critical in their efforts to resist having their own needs completely subjugated to those of their children. Participants drew on the discourses of feminism, achievement, individualism, collectivity, self-care, science, attachment, and alternative medicine in supporting their efforts to resist. They positioned themselves as caring responsible mothers, independent women, educated/professionals, critical thinkers, and activists. The findings suggest that in positioning themselves in opposition to the dominant, 'selfless mother' discourse, the participants were faced with negotiating between multiple and often contradictory discourses. In particular, the women in the study struggled to negotiate between the selfless mother and the individual rights/self actualization discourses. Furthermore, the findings suggest that the perception of resistance may be as important in engendering a sense of agency for women who mother, as the actual manifestation of resistance in their mothering practices. These findings are discussed in terms of their implications for research, theory, and clinical practice.

description: Solomonoff unified Occam's razor and Epicurus' principle of multiple explanations to one elegant, formal, universal theory of inductive inference, which initiated the field of algorithmic information theory. His central result is that the posterior of the universal semimeasure M converges rapidly to the true sequence generating posterior mu, if the latter is computable. Hence, M is eligible as a universal predictor in case of unknown mu. The first part of the paper investigates the existence and convergence of computable universal (semi)measures for a hierarchy of computability classes: recursive, estimable, enumerable, and approximable. For instance, M is known to be enumerable, but not estimable, and to dominate all enumerable semimeasures. We present proofs for discrete and continuous semimeasures. The second part investigates more closely the types of convergence, possibly implied by universality: in difference and in ratio, with probability 1, in mean sum, and for Martin-Loef random sequences. We introduce a generalized concept of randomness for individual sequences and use it to exhibit difficulties regarding these issues. In particular, we show that convergence fails (holds) on generalized-random sequences in gappy (dense) Bernoulli classes.

Edge modes of gravity. Part III. Corner simplicity constraints

description: In the tetrad formulation of gravity, the so-called simplicity constraints play a central role. They appear in the Hamiltonian analysis of the theory, and in the Lagrangian path integral when constructing the gravity partition function from topological BF theory. We develop here a systematic analysis of the corner symplectic structure encoding the symmetry algebra of gravity, and perform a thorough analysis of the simplicity constraints. Starting from a precursor phase space with Poincaré and Heisenberg symmetry, we obtain the corner phase space of BF theory by imposing kinematical constraints. This amounts to fixing the Heisenberg frame with a choice of position and spin operators. The simplicity constraints then further reduce the Poincaré symmetry of the BF phase space to a Lorentz subalgebra. This picture provides a particle-like description of (quantum) geometry: The internal normal plays the role of the four-momentum, the Barbero-Immirzi parameter that of the mass, the flux that of a relativistic position, and the frame that of a spin harmonic oscillator. Moreover, we show that the corner area element corresponds to the Poincaré spin Casimir. We achieve this central result by properly splitting, in the continuum, the corner simplicity constraints into first and second class parts. We construct the complete set of Dirac observables, which includes the generators of the local $\mathfrak{sl}(2,\mathbb{C})$ subalgebra of Poincaré, and the components of the tangential corner metric satisfying an $\mathfrak{sl}(2,\mathbb{R})$ algebra. We then present a preliminary analysis of the covariant and continuous irreducible representations of the infinite-dimensional corner algebra. Moreover, as an alternative path to quantization, we also introduce a regularization of the corner algebra and interpret this discrete setting in terms of an extended notion of twisted geometries.

description: In diesem Artikel analysieren wir Gewalt gegen, humanitären Schutz für und Bewältigungsstrategien von Frauen in Flüchtlingslagern anhand empirischer Forschung in Uganda. Auf Grundlage unserer Analysen argumentieren wir, dass Frauen in Lagern häufig sexueller und genderbasierter Gewalt ausgesetzt sind, obwohl humanitäre Organisationen Maßnahmen ergreifen, um sie zu unterstützen und zu schützen. Eine kritische Bewertung dieser Maßnahmen zeigt, dass Frauen meist durch Vulnerabilität definiert werden, wodurch ihr Handlungsvermögen vernachlässigt wird. Hingegen belegt die soziale Realität, dass Frauen diverse Strategien ergreifen, um Herausforderungen zu bewältigen und zu ihrem eigenen Schutz beizutragen.

description: The measurements of the metrological characteristics (amplitude, width, and shift in the magnetic field) of the dark pseudoresonance, which was proposed by Kazakov et al. [quant-ph/0506167] as the reference resonance for an atomic frequency standard, are reported. It has been shown that the characteristics of the pseudoresonance are worse than those of the unsplit electromagnetically induced transparency resonance for the excitation scheme with the lin||lin polarization on the D1 line of the 87Rb atom.
