description: The distribution of the maximal relative height (MRH) of self-affine one-dimensional elastic interfaces in a random potential is studied. We analyze the ground state configuration at zero driving force, and the critical configuration exactly at the depinning threshold, both for the random-manifold and random-periodic universality classes. These configurations are sampled by exact numerical methods, and their MRH distributions are compared with those with the same roughness exponent and boundary conditions, but produced by independent Fourier modes with normally distributed amplitudes. Using Pickands' theorem we derive an exact analytical description for the right tail of the latter. After properly rescaling the MRH distributions we find that corrections from the Gaussian independent modes approximation are in general small, as previously found for the average width distribution of depinning configurations. In the large size limit all corrections are finite except for the ground-state in the random-periodic class whose MRH distribution becomes, for periodic boundary conditions, indistinguishable from the Airy distribution. We find that the MRH distributions are, in general, sensitive to changes of boundary conditions.

subject: Speed Scaling
subject: Profiling
subject: Energy Efficiency

description: Speed scaling policies are a critical component in modern operating systems, impacting both energy efficiency and performance. Energy efficiency is important from a sustainability standpoint, especially since datacenters account for roughly 2% of the global energy consumption, growing by 6% per year. Understanding the features of modern processors facilitates the development of more effective policies. As a first contribution, this thesis provides such information, along with the details necessary to properly interpret experimental measurement results. The second contribution is a profiler that makes it easy to perform controlled workloads made up of precise units of work at defined speeds, and produces high-resolution timing and energy measurement data broken down by process and workload. The profiler is used to collect empirical data about several theoretical speed scaling policies using a modern processor, with detailed analysis and comparisons to the most common policy on contemporary operating systems.

description: We classify rank two Fano bundles over the Grassmannian of lines $\G(1,4)$. In particular we show that the only non-split rank two Fano bundle over $\G(1,4)$ is, up to a twist, the universal quotient bundle $\cQ$. This completes the classification of rank two Fano bundles over Grassmannians of lines.

Subjects: subject: Medicine and Surgery
subject: acute kidney injury
subject: risk prediction model
subject: non-cardiac surgery

description: Acute kidney injury (AKI) is a serious complication of major, non-cardiac surgery. Risk prediction models for AKI may be useful for informed consent processes and to identify high-risk patients to target with perioperative prevention and early intervention strategies. This thesis includes a systematic review of published prediction models for AKI following, major, non-cardiac surgery. Although seven models were identified, most were derived in small, single center cohorts, and none were externally validated. The second part of the thesis reports derivation and internal validation of five risk prediction models and a risk index based on readily available preoperative variables for predicting severe AKI requiring dialysis after major, non-cardiac surgery. The final risk index showed excellent discrimination (c-statistic 0.89) and was well calibrated. Further research to externally validate this risk index and evaluate the clinical impact of its use is needed to establish its role in perioperative care.

The experience of knowing : illusion and illumination in the Zhuangzi and the Platform Sūtra
Creators: name: Kreger, Wayne Gary
Publisher: name: University of British Columbia
Year: 2010

description: This paper aims to compare and contrast the concepts of “delusion” and “knowledge” as found in the Inner Chapters of the Zhuangzi and the Platform Sūtra. Employed in this analysis is the methodology of conceptual metaphor analysis, a method that identifies the source domain for metaphors employed in the dissemination of both doctrine and mystical experience. By acknowledging their metaphorical entailments, such metaphors can be used to more clearly elucidate the meaning of said disseminations. Ultimately I will argue that both works exhibit a similar conception of the afflictions of “non-enlightened” persons and the cognitive abilities of “enlightened” persons, though they arrive at different conclusions regarding the source of these abilities. Part one of this paper will introduce the methodology of conceptual metaphor analysis as developed by Lakoff and Johnson, and will illustrate the ways this methodology can serve the pursuit of studies in comparative religion. Following this background information relevant to the interpretation of both the Zhuangzi and the Platform Sūtra will be given. Part two investigates the metaphors and “realization” moments found in the Zhuangzi. Part three uses similar methodology to analyze the Platform Sūtra. The final part compares and contrasts the two works.

description: Accurate simulation of physical processes is crucial for the success of modern particle physics. However, simulating the development and interaction of particle showers with calorimeter detectors is a time consuming process and drives the computing needs of large experiments at the LHC and future colliders. Recently, generative machine learning models based on deep neural networks have shown promise in speeding up this task by several orders of magnitude. We investigate the use of a new architecture — the Bounded Information Bottleneck Autoencoder — for modelling electromagnetic showers in the central region of the Silicon-Tungsten calorimeter of the proposed International Large Detector. Combined with a novel second post-processing network, this approach achieves an accurate simulation of differential distributions including for the first time the shape of the minimum-ionizing-particle peak compared to a full GEANT4 simulation for a high-granularity calorimeter with 27k simulated channels. The results are validated by comparing to established architectures. Our results further strengthen the case of using generative networks for fast simulation and demonstrate that physically relevant differential distributions can be described with high accuracy.

description: Enquanto técnica, e meio (medium) a fotografia presta-se a utilizações muito diversas, em campos como o da Arte ou da Comunicação e particularmente na Publicidade enquanto comunicação comercial. Tanto num caso como noutro, a fotografia é particularmente expressiva, bebe da cultura do seu tempo e simultaneamente enforma essa mesma cultura emprestando-lhe uma materialidade fortemente impressiva e particularmente significante. O Corpo enquanto matéria, transformado em tela sobre a qual se inscrevem mensagens gritantes, é muito mais que um cenário que se constrói para enquadrar mensagens ou facilitar a comunicação com o receptor. O Corpo passa a ser a própria mensagem. É a imagem física de uma identidade que se busca hoje com sofreguidão para que possamos perceber quem somos. As remodelações desse espelho de identidades são constantes, são projectos sempre inacabados, sempre imperfeitos, com as possibilidades sempre em aberto e onde a essência do Ser não é tida como estática e absoluta. Cada vez mais, de forma mais flagrante, essa necessidade de Ser do indivíduo moderno se entrelaça com a necessidade de possuir bens de consumo que significam algo acerca da sua essência. Estes, são bens particularmente significantes, escolhidos com criteriosa atenção para compor o quadro que a tela do corpo socialmente mostra. Culturalmente, cada vez se esbatem mais as fronteiras entre Ser e Ter. O Corpo eleito como suporte privilegiado das mensagens que se pretendem construir é palco tanto das propostas artísticas, como das imagens que invadem os media e que apresentam elas próprias propostas de identidade. São deco-identidades onde os bens de consumo funcionam como adereços e o corpo é tido como espaço transformável e estilizado.

description: A sample of 427 gamma-ray bursts from a database (February 2002 - April 2008) of the RHESSI satellite is analyzed statistically. The spectral lags and peak-count rates, which have been calculated for the first time in this paper, are studied completing an earlier analysis of durations and hardness ratios. The analysis of the RHESSI database has already inferred the existence of a third group with intermediate duration, apart from the so-called short and long groups. First aim of this article is to discuss the properties of these intermediate-duration bursts in terms of peak-count rates and spectral lags. Second aim is to discuss the number of GRB groups using another statistical method and by employing the peak-count rates and spectral lags as well. The standard parametric (model-based clustering) and non-parametric (K-means clustering) statistical tests together with the Kolmogorov-Smirnov and Anderson-Darling tests are used. Two new results are obtained: A. The intermediate-duration group has similar properties to the group of short bursts. Intermediate and long groups appear to be different. B. The intermediate-duration GRBs in the RHESSI and Swift databases seem to be represented by different phenomena.

description: Delivering fast response times for user transactions is a critical requirement for Web services. Long response times can frustrate users and can cause them to discontinue using the service. Therefore, performance plays an important role in the success of a Web service. This thesis focuses on two problems related to the performance of Web services. The first problem considers Web services that rely on cloud platforms. The virtualization technologies employed by clouds can trigger contention between virtual machines, thereby leading to long response times for the Web service. This necessitates the need for automated techniques that can detect and mitigate such contentions at runtime. The second problem focuses on developing a performance prediction technique that can provide insights on how to provision the right amount of resources to the Web service. Web services can experience a variety of workloads depending on the number and the usage pattern of their end users. Operators need a systematic technique for predicting the performance of a workload under a given resource allocation. An overarching aspect of both problems is the need to predict the performance of a Web service. Most of the existing prediction techniques require an expert to devise a performance model of the system. This thesis focuses on exploring a model-free data-driven approach. Historical performance logs of a Web service in combination with a machine learning approach is used. The use of the machine learning algorithm helps in providing predictions for workloads not directly observed in past. Results show that the proposed approach is more effective at contention detection than the baseline techniques and the output can be used to mitigate performance contention effectively. Results for response time percentile prediction show that the designed technique can predict response time percentiles with high accuracy for a wide variety of workloads. This technique can accurately estimate the resources needed to maintain response time percentiles within operator-specified thresholds.
Cities as brands: the role of communication strategy in place marketing context

description: This paper acknowledges the role of place marketing and city branding as driver of economic development. It is a very important strategic decision for a place to start systematic place marketing in order to increase the competitiveness aiming to attract the scarce sources of wealth. This paper aims to contribute to the conceptualization of the city branding theoretical framework. The importance of the destination self-congruity in the creation of a tourist-destination brand relationship is related with the concept of innovative salient experiences as a key success factor in a place marketing strategy. Also the benefits caused by image transference from city brand image to city-of-origin products are discussed.

description: Toroidal orbifolds and their resolutions are described within the framework of (2,2) Gauged Linear Sigma Models (GLSMs). Our procedure describes two-tori as hypersurfaces in (weighted) projective spaces. The description is chosen such that the orbifold singularities correspond to the zeros of their homogeneous coordinates. The individual orbifold singularities are resolved using a GLSM guise of non-compact toric resolutions, i.e. replacing discrete orbifold actions by Abelian worldsheet gaugings. Given that we employ the same global coordinates for both the toroidal orbifold and its resolutions, our GLSM formalism confirms the gluing procedure on the level of divisors discussed by Lust et al. Using our global GLSM description we can study the moduli space of such toroidal orbifolds as a whole. In particular, changes in topology can be described as phase transitions of the underlying GLSM. Finally, we argue that certain partially resolvable GLSMs, in which a certain number of fixed points can never be resolved, might be useful for the study of mini-landscape orbifold MSSMs.

description: Single particle momentum spectra are calculated within three micro-canonical statistical ensembles, namely, with conserved system energy, system momentum, as well as system energy and momentum. Deviations from the exponential spectrum of the grand canonical ensemble are quantified and discussed. For mean particle multiplicity and temperature, typical for p+p interactions at the LHC energies, the effect of the conservation laws extends to transverse momenta as low as about 3 GeV/c. The results may help to interpret spectra measured in nuclear collisions at high energies, in particular, their system size dependence.

description: Wind energy is recognized as an important component of the world’s energy mix. Despite its widely acknowledged advantage as a renewable energy resource, the development of wind farms in the last 20 years has posed a critical challenge for land use planning in Alberta. In view of this, there are compelling arguments that effective, place-specific decision support tools would enable stakeholders identify appropriate placement locations for wind farms in Alberta. The research presented in thesis empirically examined ways in which a decision support tool can be developed to achieve the goal stated above. A socio-technical approach was used to identify the decision support requirements of wind energy stakeholders in Alberta and to develop a conceptual framework in response to the requirements. Further research was conducted to determine the underlying attributes of effective visual analytics decision support tools, and how those attributes can be applied to the design of the proposed tool. Based on the established requirements, attributes, and conceptual framework, a proof-of-concept, web-based Alberta Wind decision support tool (AB–WINDEC) tool was implemented using iterative prototyping techniques. The prototype was first assessed through an expert appraisal. It was subsequently evaluated in focus groups with wind energy stakeholders in Alberta. Focus group participants reviewed the conceptual system design in the following areas: usability, usefulness, analytical support, and capability to support tasks and data management. These findings suggest that AB–WINDEC can be useful for educational purposes, public engagement, high-level analysis, risk assessment, and collaboration. The main contributions of this thesis and the research described in it are four-fold: It extends current knowledge by bringing together, for the first time, the decision support requirements of stakeholders involved in planning the placement of wind farms in Alberta. Thus, it was possible to develop a conceptual framework that integrated the dual aspects of AB–WINDEC as a social and technical decision support tool. Progress was made in multi-disciplinary areas of visual analytics, product design, product experience, prototyping, and design research. Finally, the thesis shows that knowledge gained from empirical research can inform the development of an effective visual analytics decision support tool.

description: Esta comunicação discute como se processaram algumas transformações em hábitos de consumo feminino, diante da recente segmentação do produto cosmético, em atendimento a diversas faixas etárias desse público consumidor. O fenômeno classificatório e diferenciador do cosmético, e a consequente alteração do perfil identitário do público consumidor, devem-se, principalmente, a alguns fatores: a) presença de antigos e instauração de novos marcos biológicos que recomendam e norteiam o princípio dos cuidados com o corpo; b) constante tentativa da publicidade de incluir o cosmético no rol das mercadorias de primeira necessidade; c) crescente democratização dos cuidados estéticos possibilitada, em parte, pela expansão dos meios de comunicação; d) e o interesse econômico, relacionado com a produção industrial de mercadorias para vários nichos do mercado consumidor. Estes aspectos serão examinados por meio de análise linguísticodiscursiva de anúncios publicitários impressos em revistas femininas, no Brasil.

description: This thesis focuses on the optimization of a coal-fired power plant with carbon capture and amine storage and the importance of the modelling parameters to the objective and scheduling result. The first part of this thesis will develop a linear mixed-integer model for a coal-fired power plant that considers the power losses in the steam cycle that come from simultaneous and separate changes in the operation levels of the power plant and carbon dioxide stripper. The model developed will be compared to a model representing the methods used in current literature. The second part of this thesis will perform a sensitivity analysis on the modelling parameters in order to recommend the areas of carbon capture and amine storage modelling that would benefit from increased detail in future work. The analysis will consider the effect of the parameters on the optimization objective and the resulting schedule.

description: New Crystal Barrel data are reported for pbar-p -> omega-eta and pbar-p -> omega-pizero-pizero with omega decaying to piplus-piminus-pizero. The omega-eta data confirm angular distributions obtained earlier from data where omega -> pizero-gamma. The new omega-eta data provide accurate measurements of vector and tensor polarisations of the omega and lead to considerable improvements in masses and widths of s-channel resonances. A new J^PC = 3^+- I = 0 resonance is observed with mass M = 2025+-20 MeV and width Gamma = 145+-30 MeV. Polarisation is close to zero everywhere and tensor polarisations are large, as is the case also for pbar-p -> omega-pizero.

description: As raízes mais profundas da noção de publicidade ou, mais precisamente, de público remontam à antiguidade. Nessa altura, a vida pública desenvolve-se na agora e “a publicidade constitui-se na conversação (lexis), que pode também tomar a forma da deliberação e do tribunal, assim como no fazer comum (praxis)” (Habermas,1981: 43). Por contraposição à esfera privada, emerge a publicidade, “como um reino da liberdade e da continuidade. À luz da publicidade tudo se manifesta tal como é, tudo se faz a todos visível. Na conversação entre cidadãos as coisas fluem através da linguagem e ganham forma; na disputa entre iguais sobressaem os melhores e estes ganham a sua essência: a imortalidade da fama” (Ibidem: 43). Contudo, o sentido moderno da palavra publicidade surge apenas na primeira metade do século XIX, com o desenvolvimento da sociedade industrial e com o nascimento das primeiras agências de publicidade, quer na Europa quer nos Estados Unidos. Até então, a publicidade pretendia, sobretudo, designar a actividade de tornar público, de divulgar, de difundir produtos ou serviços, bem como os respectivos locais de venda, ou mesmo promover espectáculos e outros eventos, inicialmente através do pregão e das tabuletas e, mais tarde, com o aparecimento da imprensa, na primeira metade do século XV, através do cartaz e dos pequenos anúncios, os quais só apareceriam no século XVII 1.

Paleobiology (West Texas, USA), biostratigraphy and paleogeography (Vancouver Island, Canada) of late Paleozoic conodonts

description: Three conodont-related studies utilize techniques that highlight the diverse applicability and elucidate more about the nature of these ancient microfossils. These studies impact and utilize paleontology, geochemistry, biostratigraphy, stratigraphy, sedimentology, paleoecology, and the paleogeography of tectono-stratigraphic terranes. Electron microprobe analyses of conodont elements reveal internal chemical distributions which support the theory that conodont elements functioned as exposed teeth within the conodont animal’s oral cavity. The mineralized crown of the conodont element was partially embedded within soft tissue like other vertebrate teeth. To prevent unwanted sampling of diagenetic alteration, distributions of geochemically important chemical elements warrant consideration in geochemical studies investigating or utilizing conodonts. Paleozoic conodonts from Vancouver Island are described and figured in the most thorough compilation from the region. A wide variety of genera spanning the Mississippian through Early Permian represent a significant biostratigraphic and taxonomic contribution. Conodont Color Alteration Index values provide insight into the highly variable thermal history of the region. Interpretations of the upper Paleozoic units of Vancouver Island are improved by new biostratigraphic and paleoecologic data from conodonts. In conjunction with new stratigraphic and sedimentologic data, stratigraphic correlations and interpretations of depositional environment reveal a topographically variable basin with shallower water carbonates grading downslope into carbonate, mudstone, and chert. A combination of new and previously published fossil data, including conodonts, strongly indicate that, in the late Paleozoic, Vancouver Island was close to northwestern Pangaea and at latitudes comparable to southeastern British Columbia. Fossil and paleomagnetic data from the Mesozoic are congruent with this interpretation. Based on stratigraphic and paleogeographic differences, the Paleozoic of Vancouver Island is assigned to the Vancouver terrane separate from the Alaskan Wrangell terrane.

description: This thesis reports advances in the theory of design, characterization and simulation of multi- photon multi-channel interferometers. I advance the design of interferometers through an algorithm to realize an arbitrary discrete unitary transformation on the combined spatial and internal degrees of freedom of light. This procedure effects an arbitrary n_s n_p × n_s n_p unitary matrix on the state of light in n_s spatial and n_p internal modes. The number of beam splitters required to realize a unitary transformation is reduced as compared to existing realization by a factor n_p^2/2. I thus enable the optical implementation of higher dimensional unitary transformations. I devise an accurate and precise procedure for characterizing any multi-port linear optical interferometer using one- and two-photon interference. Accuracy is achieved by estimating and correcting systematic errors that arise due to spatiotemporal and polarization mode mismatch. Enhanced accuracy and precision are attained by fitting experimental coincidence data to a curve simulated using measured source spectra. The efficacy of our characterization procedure is verified by numerical simulations. I develop group-theoretic methods for the analysis and simulation of linear interferometers. I devise a graph-theoretic algorithm to construct the boson realizations of the canonical SU(n) basis states, which reduce the canonical subgroup chain, for arbitrary n. The boson realizations are employed to construct D-functions, which are the matrix elements of arbitrary irreducible representations, of SU(n) in the canonical basis. I show that immanants of principal submatrices of a unitary matrix T are a sum Σ_tD^{(λ)}_{tt}(Ω) of the diagonal D-functions of group element Ω, with t determined by the choice of submatrix, and the irrep (λ) determined by the immanant under consideration. The algorithm for SU(n) D-function computation and the results connecting these functions with immanants open the possibility of group-theoretic analysis and simulation of linear optics.

description: A cyclotomic polynomial Φ_n(x) is said to be ternary if n=pqr with p,q and r distinct odd primes. Ternary cyclotomic polynomials are the simplest ones for which the behaviour of the coefficients is not completely understood. Here we establish some results and formulate some conjectures regarding the coefficients appearing in the polynomial family Φ_{pqr}(x) with p

A mulher “objecto” na publicidade
Creators: name: Veríssimo, Jorge Domingos Carapinha

Year: 2005

description: Apesar da vulgaridade com que hoje em dia é usada a expressão “corpo objecto” são vários os autores que a empregam em qualquer representação do corpo da mulher destinada a promover produtos masculinos ou femininos esta comunicação, fruto de uma investigação inserida no contexto da minha tese de Doutoramento, intitulada As representações do corpo na publicidade, já apresentada publicamente no ISCTE (12 de Maio de 2005), visa demonstrar que este conceito apenas se deve aplicar aquando do recurso gratuito e primário de corpos femininos reveladores de determinados detalhes da sua feminilidade poses sensuais ou mesmo eróticas, corpos seminus ou nus e limitados à promoção de produtos masculinos, tal qual defendem Villegas e Chica: «é preciso reconhecer que o tratamento da mulher como objecto sexual passivo emerge de um modo dominante em anúncios dirigidos de forma exclusiva ou prevalecente aos homens: produtos de barbear, roupa masculina, determinados modelos de automóveis, bebidas alcoólicas, etc.» (2001, 40). 1 Nestas situações, a mulher acaba por ser ela própria um produto, um objecto, já que emerge nas mais diversas poses, funcionando como um elemento altamente persuasivo. Para demonstrar a esta posição recorri a uma vasta metodologia de análise da imagem, da qual destaco o inventário de figuras de retórica da imagem publicitária oferecida por J. Durand (1972); os níveis de codificação da imagem publicitária propostos por Umberto Eco (1987); o estudo de Kathy Myers (1995), uma investigadora norteamericana que, baseada nas teorias feministas se dedica ao estudo da mulher na publicidade; e os trabalhos de LazierSmith (citado por Gauli, 2000), investigador americano que analisou, de um modo contínuo, nos anos 70 e 80, a publicidade norteamericana, mais especificamente a publicidade das revistas, MS, Playboy, Time e Nensweek. Esta metodologia foi aplicada a um extenso corpus de anúncios, com especial incidência da marca Calvin Klein.

description: Space instrumentation like SOHO, MOST, CoRoT and Kepler has been and is being built to attain very high precision data to be used for asteroseismic analysis. Nonetheless, there is a very strong need for providing additional information, especially on mode identification. With this contribution I will review the efforts been put on new ground-based instrumentation and the methodology that can be used to achieve this aim.

Analysis of the Heyd-Scuseria-Ernzerhof density functional parameter space

description: The Heyd-Scuseria-Ernzerhof (HSE) density functionals are popular for their ability to improve the accuracy of standard semilocal functionals such as Perdew-Burke-Ernzerhof (PBE), particularly for semiconductor band gaps. They also have a reduced computational cost compared to hybrid functionals, which results from the restriction of Fock exchange calculations to small inter-electron separations. These functionals are defined by an overall fraction of Fock exchange and a length scale for exchange screening. We systematically examine this two-parameter space to assess the performance of hybrid screened exchange (sX) functionals and to determine a balance between improving accuracy and reducing the screening length, which can further reduce computational costs. Three parameter choices emerge as useful: "sX-PBE" is an approximation to the sX-LDA screened exchange density functionals based on the local density approximation (LDA); "HSE12" minimizes the overall error over all tests performed; and "HSE12s" is a range-minimized functional that matches the overall accuracy of the existing HSE06 parameterization but reduces the Fock exchange length scale by half. Analysis of the error trends over parameter space produces useful guidance for future improvement of density functionals.

Early Childhood Human Capital

subject: Education--Early Childhood

description: This thesis consists of three essays examining the early childhood human capital. The first chapter sets out to identify the effect of sibling birth spacing on children's academic achievement and engagement in risky behaviours by using data from the National Longitudinal Survey of Youth (NLSY79). Some unobservable variables in the family such as parental personality or wealth can affect both spacing and a child's performance and may cause an endogeneity problem. To overcome this, I use family fixed effect to control for unobservable family-specific characteristics. The second chapter investigates the influence of the ``No Child Left Behind'' (NCLB) act, based not only on its own target but also on the unintended consequences of this act. More specifically, I evaluate the effect of this act on mathematics and reading using a new approach and investigate whether this act did, in fact, reduce the educational gap between different subgroups. Furthermore, I consider two aspects as unintended consequences of this act: first, the impact of the NCLB act on students' test scores in untargeted skills such as non-cognitive skills and science; and second, the effect on the distribution of students' test scores. Using the Early Childhood Longitudinal Survey-Kindergarten data set, I implement the difference-in-difference methodology between public schools receiving Title-I federal funding versus public schools not receiving federal funding because only Title-I public schools were penalized by this act. Moreover, since low and high performing students might be affected differently, I use the quantile regression to evaluate the distributional effect of this act. The third chapter explores the mechanisms behind the NCLB act. I consider two channels of change: improving teaching productivity and reallocating time at the expense of non-targeted courses. To investigate these two channels, I develop a model of a school optimization behavior and a production function of skill formation. The estimated parameters of the model, together with data from the Early Childhood Longitudinal Study-Kindergarten, are used to conduct a counter-factual experiment to find time allocation in targeted and non-targeted skills if this act had not been implemented.
