Architecture and the Production of Postcard Images: Tradition vs. Critical Regionalism in Curitiba
Creators: name: Irazabal Zurita, Clara E.
Publisher: name: Columbia University
Year: 1998
Subjects: subject: Architecture
subject: FOS: Civil engineering

description: In Curitiba, Brazil, the building of architectural monuments that make use of a direct vocabulary of tradition has been one of the major means to construct the city image in the last two decades. The government of Curitiba has plagued the city with foreign-styled landmarks mostly based on selective samples of European traditions. Such attempts strive to construct a city image that creates a sense that Curitiba has a heritage connected with the European established traditions. Examples of those ethnic landmarks are the Polonaise Memorial, and the German, Italian and Portuguese parks. Such monuments depict a cosmopolitan, international city, freed from the tortuous memories of black slavery and Indian submission that tint history elsewhere in Brazil. This selective editing of history valorizes and idealizes parts of the pasts, while erasing others.
Two-body Coulomb scattering and complex scaling

description: The two-body Coulomb scattering problem is solved using the standard complex scaling method. The explicit enforcement of the scattering boundary condition is avoided. Splitting of the scattering wave function based on the Coulomb modified plane wave is considered. This decomposition leads a three-dimensional Schrödinger equation with source term. Partial wave expansion is carried out and the asymptotic form of the solution is determined. This splitting does not lead to simplification of the scattering boundary condition if complex scaling is invoked. A new splitting carried out only on partial wave level is introduced and this method is proved to be very useful. The scattered part of the wave function tends to zero at large inter-particle distance. This property permits of easy numerical solution: the scattered part of the wave function can be expanded on bound-state type basis. The new method can be applied not only for pure Coulomb potential butin the presence of short range interaction too.

description: There are a number of different phenomena in the early universe that have to be studied numerically with lattice simulations. This paper presents a graphics processing unit (GPU) accelerated Python program called PyCOOL that solves the evolution of scalar fields in a lattice with very precise symplectic integrators. The program has been written with the intention to hit a sweet spot of speed, accuracy and user friendliness. This has been achieved by using the Python language with the PyCUDA interface to make a program that is easy to adapt to different scalar field models. In this paper we derive the symplectic dynamics that govern the evolution of the system and then present the implementation of the program in Python and PyCUDA. The functionality of the program is tested in a chaotic inflation preheating model, a single field oscillon case and in a supersymmetric curvaton model which leads to Q-ball production. We have also compared the performance of a consumer graphics card to a professional Tesla compute card in these simulations. We find that the program is not only accurate but also very fast. To further increase the usefulness of the program we have equipped it with numerous post-processing functions that provide useful information about the cosmological model. These include various spectra and statistics of the fields. The program can be additionally used to calculate the generated curvature perturbation. The program is publicly available under GNU General Public License at https://github.com/jtksai/PyCOOL .

description: An active network is a network infrastructure which is programmable on a per-user or even per-packet basis. Increasing the flexibility of such network infrastructures invites new security risks. Coping with these security risks represents the most fundamental contribution of active network research. The security concerns can be divided into those which affect the network as a whole and those which affect individual elements. It is clear that the element problems must be solved first, since the integrity of network-level solutions will be based on trust in the network elements. In this article we describe the architecture and implementation of a secure active network environment (SANE), which we believe provides a basis for implementing secure network-level solutions. We guarantee that a node begins operation in a trusted state with the AEGIS secure bootstrap architecture. We guarantee that the system remains in a trusted state by applying dynamic integrity checks in the network element's runtime system, using a novel naming system, and applying node-to-node authentication when needed. The construction of an extended LAN is discussed.
Renormalization approach to bound state energy computation for two ultracold atoms in an optical lattice
Creators: name: Borzov, Dmitry
Publisher: name: University of British Columbia
Year: 2011

description: In experiments with ultra-cold gases, two alkali atoms, that interact with repulsive or attractive potentials and are confined to an optical lattice, can form bound states. In order to compute the energy of such states formed by atoms in the lowest Bloch band, one needs to take into account the intra-band corrections arising from contributions by higher Bloch bands. As it is hard to implement, known calculations tend to neglect them altogether thus setting up a limit for the precision of such computations. To address the problem we apply an approach that uses renormalization-group equations for an effective potential we introduce. It allows for the expression of the bound state energy in terms of the free-space interaction scattering length and parameters of confining potentials. Expressions for bound state energies in 1D, 2D and 3D optical lattices are reported. We show that the method we use can be easily tailored to various cases of atoms confined by external fields of other geometries. A known result for atoms confined to a quasi-2D system is reproduced as an example. Universality of the approach makes it a useful tool for such class of problems.

description: Using a merged-beam technique, the absolute, total electron-capture cross section has been measured for collisions of Ne2+ ions with hydrogen (deuterium) atoms at collision energies between 139 and 1490 eV/u. These data are compared to three other published measurements, two of which differ from one another by a factor greater than two. Early quantal rate coefficient calculations for Ne2+ ions with hydrogen at eV/u energies predict a cross section many orders of magnitude below the previously measured cross section at 40 eV/u. A possible explanation is given for the discrepancy between theory and experiment.
Equivalence of Wilson Loops in ABJM and N = 4 SYM Theory
Creators: name: Wiegandt, Konstantin
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Theory (hep-th)

description: In previous investigations, it was found that four-sided polygonal light-like Wilson loops in ABJM theory calculated to two-loop order have the same form as the corresponding Wilson loop in N = 4 SYM at one-loop order. Here we study light-like polygonal Wilson loops with n cusps in planar three-dimensional Chern-Simons and ABJM theory to two loops. Remarkably, the result in ABJM theory precisely agrees with the corresponding Wilson loop in N = 4 SYM at one-loop order for arbitrary n. In particular, anomalous conformal Ward identites allow for a so-called remainder function of conformal cross ratios, which is found to be trivial at two loops in ABJM theory in the same way as it is trivial in N = 4 SYM at one-loop order. Furthermore, the result for arbitrary n obtained here, allows for a further investigation of a Wilson loop / amplitude duality in ABJM theory, for which non-trivial evidence was recently found by a calculation of four-point amplitudes that match the Wilson loop in ABJM theory.

description: In the United States, national public preparedness efforts meant to ready individuals and families for disasters have been driven primarily by international threats, actual or anticipated. These include terrorism, war and the potential for global instability such as the millennium Y2K computer error. The national dialogue on public preparedness following Hurricanes Katrina and Rita in the fall of 2005 is a notable departure from the more typical focus of public preparedness, which is oriented toward terrorism and international threats. However, the response to the hurricanes was largely viewed as an unanticipated test of the public’s readiness for a disaster and the penetration of the public preparedness messages that have been actively promulgated since 11 September 2001. As such, we argue that the poor state of public readiness that was found in the U.S. Gulf Coast region after the hurricanes actually reflects a national state of unpreparedness for emergency events despite the post-September 11th calls from all levels of government for the U.S. public to be prepared.

description: The Higgs sector of the Standard Model offers a unique probe of the hidden sector. In this work, we explore the possibility of renormalizable Higgs couplings to the hidden sector vector fields which can constitute dark matter (DM). Abelian gauge sectors with minimal field content, necessary to render the gauge fields massive, have a natural Z_2 parity. This symmetry ensures stability of the vector fields making them viable dark matter candidates, while evading the usual electroweak constraints. We illustrate this idea with the Stueckelberg and Higgs mechanisms. Vector DM is consistent with the WMAP, XENON100, and LHC constraints, while it can affect significantly the invisible Higgs decay. Due to the enhanced branching ratio for the Higgs decay into the longitudinal components of the vector field, the vector Higgs portal provides an efficient way to hide the Higgs at the LHC. This could be the reason why the latest combined ATLAS/CMS data did not bring evidence for the existence of the Higgs boson.

Access Denied: Taking Action for Medically Underserved Children

Child health services

description: Advocacy centered on access to health care for children is a straightforward
business. The goal is clear: children need readily available, comprehensive, continuity-based, family-friendly, and child-friendly health services to meet a range of well-accepted objectives, including preventing, screening, acute care as needed, management of chronic conditions, and anticipatory guidance. Pediatricians refer to such a health care environment as a "medical home." Children who, for any reason, are unable to access such care are considered medicalIy underserved. Although wide-ranging barriers interfere with access to medical homes for millions of children, particular populations remain at high risk for chronically poor access. These are precisely the groups that require focused and sustained attention from advocates and policymakers. The fact is that serving vulnerable populations, such as homeless children, involves more than designing good programs, important as this may be. Often, the greater challenge is to understand and manage the barriers that keep such families from being able to utilize whatever services might be available. This paper proposes a strategic approach for programs dealing with health care services for severely medically underserved children. Accordingly, it is important to begin by attempting to understand the functional or operational definition of "health care access" and to derive therefrom a clear sense of the specific barriers that impede access.

description: While users today have access to many tools that assist in performing large scale data analysis tasks, understanding the performance characteristics of their parallel computations, such as MapReduce jobs, remains difficult. We present PerfXplain, a system that enables users to ask questions about the relative performances (i.e., runtimes) of pairs of MapReduce jobs. PerfXplain provides a new query language for articulating performance queries and an algorithm for generating explanations from a log of past MapReduce job executions. We formally define the notion of an explanation together with three metrics, relevance, precision, and generality, that measure explanation quality. We present the explanation-generation algorithm based on techniques related to decision-tree building. We evaluate the approach on a log of past executions on Amazon EC2, and show that our approach can generate quality explanations, outperforming two naive explanation-generation methods.

description: Proposals for programmable network infrastructures, such as active networks and open signaling, provide programmers with access to network resources and data structures. The motivation for providing these interfaces is accelerated introduction of new services, but exposure of the interfaces introduces many new security risks. We describe some of the security issues raised by active networks. We then describe our secure active network environment (SANE) architecture. SANE was designed as a security infrastructure for active networks, and was implemented in the SwitchWare architecture. SANE restricts the actions that loaded modules can perform by restricting the resources that can be named; this is further extended to remote invocation by means of cryptographic credentials. SANE can be extended to support restricted control of quality of service in a programmable network element. The Piglet lightweight device kernel provides a "virtual clock" type of scheduling discipline for network traffic, and exports several tuning knobs with which the clock can be adjusted. The ALIEN active loader provides safe access to these knobs to modules that operate on the network element. Thus, the proposed SQoSH architecture is able to provide safe, secure access to network resources, while allowing these resources to be managed by end users needing customized networking services. A desirable consequence of SQoSH's integration of access control and resource control is that a large class of denial-of-service attacks, unaddressed solely with access control and cryptographic protocols, can now be prevented.

description: In Europe, wild reindeer was an important source of human food during the last glaciation. Presently the last remnants of the wild European mountain living reindeer survive in southern Norwegian mountains where they move nomadically between summer and winter ranges. The reindeer ranges belong to different counties and municipalities and are owned by private persons and public institutions. The ranges are threatened by human development, and reindeer is a hunted species. The landowner has the hunting rights on own grounds. During a long political process, each reindeer mountain range has been defined, and regional development plans with zones of no development, buffer zones and zones with some development have been approved. A board of landowners and a national board with members from each municipality manage the reindeer according to the plan and National regulations. The national board has the right to oppose all development plans inside the reindeer ranges and will usually be heard by National authorities. The landowner board make harvest plans that must be approved by the national board. In this talk, I will describe the management system that is one example of how a vulnerable hunted species and its habitat crossing private and political borders may be managed.

description: The terror attacks of Sept. 11, 2001, on the World Trade Center in New York City and the Pentagon in Washington, D.C., are unique in American history. The magnitude of the attack in New York, in terms of loss of life and property, was enormous. The destroyed twin towers of the World Trade Center had a total of 10 million square feet of rentable office space with capacity for 50,000 occupants. Five other buildings in the Trade Center complex, a church, a 22 story hotel, and a 54 -story office building also were either destroyed or seriously damaged. Reports of the death toll are conflicting. The New York City Department of Health reports 2,617 deaths based on death certificates issued through Jan. 25, 2002 others estimate the total exceeds 3,000. Furthermore, the actual attacks, including the moment of the second plane crashing into the World Trade Center, were shown repeatedly by nearly every television station in the country over the next several days.
Many children who witnessed any aspect of the terrorist attack, either directly or via the media, showed evidence of behavioral or psychological reactions to the events of 9/11 and the subsequent scare involving dissemination of anthrax spores through the mail. To determine the nature, extent, and distribution of the impact of these events on children and families in New York City, C HF commissioned a series of polls from the Marist Institute.

description: We discuss the recombination of brane/anti-brane pairs carrying $D3$ brane charge in $AdS_5 \times S^5$. These configurations are dual to co-dimension one defects in the ${\cal N}=4$ super-Yang-Mills description. Due to their $D3$ charge, these defects are actually domain walls in the dual gauge theory, interpolating between vacua of different gauge symmetry. A pair of unjoined defects each carry localized $(2+1)$ dimensional fermions and possess a global $U(N)\times U(N)$ flavor symmetry while the recombined brane/anti-brane pairs exhibit only a diagonal U(N). We study the thermodynamics of this flavor-symmetry breaking under the influence of external magnetic field.

description: Thermal radiative energy transfer between closely spaced surfaces has been analyzed in the past and shown not to obey the laws of classical radiation heat transfer owing to evanescent waves and, more recently, electromagnetic surface modes. We have analyzed the energy transfer between layered media, one of the layers being the thermal source, using a Green’s functions method and the fluctuation-dissipation theorem. Based on the analysis, we propose a structure that can utilize the surface modes to increase the power density and efficiency of low temperature thermophotovoltaic generators. © 2003 American Institute of Physics.

description: We present updated global fits of the constrained Minimal Supersymmetric Standard Model (cMSSM), including the most recent constraints from the ATLAS and CMS detectors at the LHC, as well as the most recent results of the XENON100 experiment. Our robust analysis takes into account both astrophysical and hadronic uncertainties that enter in the calculation of the rate of WIMP-induced recoils in direct detection experiment. We study the consequences for neutralino Dark Matter, and show that current direct detection data already allow to robustly rule out the so-called Focus Point region, therefore demonstrating the importance of particle astrophysics experiments in constraining extensions of the Standard Model of Particle Physics. We also observe an increased compatibility between results obtained from a Bayesian and a Frequentist statistical perspective. We find that upcoming ton-scale direct detection experiments will probe essentially the entire currently favoured region (at the 99% level), almost independently of the statistical approach used. Prospects for indirect detection of the cMSSM are further reduced.

There are issues in terms of the detection/non-detection of the bright source when comparing the Spitzer, WISE, and PACS observations. It is apparently inconsistent, perhaps due to variability or low signal-to-noise of the data. We have looked into the possible misidentification of the target, and have revised the measured SPIRE fluxes and the disc parameters for 2M1207. We have also reviewed which among the various formation mechanisms of this system would still be valid.

description: Accommodation plays such an important role in the tourist's experience, and one would imagine that many studies concerning this topic have been conducted. However, surprisingly very few studies have been carried out on this subject despite the growth in both demand and supply. This gap or lack of research led to the present exploratory study that addressed the question: what are visitors' accommodation preferences when they select accommodation in the Kruger National Park (KNP)? Based on a visitor survey in the Northern region of the Park during December 2015 where295 fully completed questionnaires were administered, respondents were segmented based on their accommodation preferences (self-serviced, serviced and safari). Three distinct clusters were identified, Self-service seekers, Service seekers, and Safari, service seekers. These clusters differ regarding their socio-demographic characteristics and especially regarding the factors they regard as important when selecting accommodation and campsites. This was the first time that the accommodation preferences of visitors to the flagship national park in South Africa were analysed. The results show that while visitors to the KNP appear homogeneous regarding their demographic profile, they differ significantly when it comes to accommodation needs and preferences. The findings from the research are valuable to park management especially when developing and expanding accommodation options in the park as it shows the preferences of each distinct market. This research furthermore makes a contribution to the current literature regarding ecotourism and ecotourists' accommodation preferences.

Social art effect : the a/r/tography and complexity of theatre education learning systems, developmental stages, and change mechanisms
Creators: name: Beare, David Merritt
Publisher: name: University of British Columbia

description: This study examined how the Compassion Project, a collective theatre and social learning program, fostered positive youth and group development. The Compassion Project involved over 200 secondary students who participated in four theatre-making and social learning phases, where they inquired upon the topic of safe and caring schools. Through the process of collective theatre-making, students co-created two original plays (The Flip Side and Focus) about their social and emotional experiences in school. A/r/tography, the arts education research methodology for this study, emphasizes living inquiry and reflective practice through the examination of the in-between spaces of art-making/researching/teaching (a/r/t). Expanding upon the field of a/r/tography, this study introduces the rendering of the fourth wall as a theatre education research lens. By conceptualizing the theatre classroom as a stage, the rendering of the fourth wall directs attention to several perspectives: to the students, teacher-directors, players, and audience on both the classroom and stage sides; to the spaces in between the imaginary world of the play and the real life experiences of the inquirers; and, to the theatre-making and reflective practices. Based on observations, interviews, circle talks, and students’ written reflections, stories, and scripts, the data are analyzed and presented throughout the dissertation. The findings are conceptualized as the social art effects, which are the benefits that result from students’ social and theatre-making actions and interactions. The conceptualization also combines psychological, pedagogical, and theatre-based theories, such as positive psychology, complexity in education, and collective theatre. As a way to organize the data, the findings on the social art effect are categorized into three components: learning systems, developmental stages, and change mechanisms. This study illustrates how students’ social conditions are critical, and precede learning conditions. Furthermore, this study emphasizes the importance of integrating social learning and complex systems theories into the curriculum as a way to optimize learning spaces and to foster positive youth and group development.

description: We have investigated the accuracy of the 1s vacancy fluorescence database of Kaastra and Mewe resulting from the initial atomic physics calculations and the subsequent scaling along isoelectronic sequences. In particular, we have focused on the relatively simple Be- and F-like 1s vacancy sequences. We find that the earlier atomic physics calculations for the oscillator strengths and autoionization rates of singly charged B II and Ne II are in sufficient agreement with our present calculations. However, the substantial charge dependence of these quantities along each isoelectronic sequence, the incorrect configuration averaging used for B II, and the neglect of spin-orbit effects (which become important at high Z) all cast doubt on the reliability of the Kaastra and Mewe data for application to plasma modeling.

description: We discuss opportunities that may arise from subjecting high-multiplicity events in relativistic heavy ion collisions to an analysis similar to the one used in cosmology for the study of fluctuations of the Cosmic Microwave Background (CMB). To this end, we discuss examples of how pertinent features of heavy ion collisions including global characteristics, signatures of collective flow and event-wise fluctuations are visually represented in a Mollweide projection commonly used in CMB analysis, and how they are statistically analyzed in an expansion over spherical harmonic functions. If applied to the characterization of purely azimuthal dependent phenomena such as collective flow, the expansion coefficients of spherical harmonics are seen to contain redundancies compared to the set of harmonic flow coefficients commonly used in heavy ion collisions. Our exploratory study indicates, however, that these redundancies may offer novel opportunities for a detailed characterization of those event-wise fluctuations that remain after subtraction of the dominant collective flow signatures. By construction, the proposed approach allows also for the characterization of more complex collective phenomena like higher-order flow and other sources of fluctuations, and it may be extended to the characterization of phenomena of non-collective origin such as jets.

description: As an approach to describe the long-range properties of non-Abelian gauge theories at non-zero temperature T < T_c, we consider a non-interacting ensemble of dyons (magnetic monopoles) with non-trivial holonomy. We show analytically, that the quark-antiquark free energy from the Polyakov loop correlator grows linearly with the distance, and how the string tension scales with the dyon density. In numerical treatments, the long-range tails of the dyon fields cause severe finite-volume effects. Therefore, we demonstrate the application of Ewald's summation method to this system. Finite-volume effects are shown to be under control, which is a crucial requirement for numerical studies of interacting dyon ensembles.

Hurricane Katrina (2005)

description: If humans did not occupy the planet, disasters would never occur. Massive climatic events, earthquakes, volcanic eruptions, and tsunamis would be regular occurrences, of course, and the earth would look like a dynamic cauldron of natural activity, changing the look and the balance of nature and natural events continuously and randomly. What morphs these natural phenomenon into catastrophic events we call “disasters” is simply the presence of human beings who by choice, chance, or necessity find themselves in harm’s way. The “human factors” may be straightforward and benign. For instance, people making their livelihood from the sea are at risk from coastal storms and tsunamis. Similarly, people are found living in areas at considerable risk for mudslides and volcanoes. It could even be said that living in New Orleans, a coastal city actually below sea level, is a gamble, as was so dramatically emphasized by the storms and subsequent flooding of August and September 2005.
Uncertain Centroid based Partitional Clustering of Uncertain Data

description: Clustering uncertain data has emerged as a challenging task in uncertain data management and mining. Thanks to a computational complexity advantage over other clustering paradigms, partitional clustering has been particularly studied and a number of algorithms have been developed. While existing proposals differ mainly in the notions of cluster centroid and clustering objective function, little attention has been given to an analysis of their characteristics and limits. In this work, we theoretically investigate major existing methods of partitional clustering, and alternatively propose a well-founded approach to clustering uncertain data based on a novel notion of cluster centroid. A cluster centroid is seen as an uncertain object defined in terms of a random variable whose realizations are derived based on all deterministic representations of the objects to be clustered. As demonstrated theoretically and experimentally, this allows for better representing a cluster of uncertain objects, thus supporting a consistently improved clustering performance while maintaining comparable efficiency with existing partitional clustering algorithms.

description: In order to reproduce the low mass end of the stellar mass function, most current models of galaxy evolution invoke very efficient supernova feedback. This solution seems to suffer from several shortcomings however, like predicting too little star formation in low mass galaxies at z=0. In this work, we explore modifications to the star formation (SF) law as an alternative solution to achieve a match to the stellar mass function. This is done by applying semi-analytic models based on De Lucia & Blaizot, but with varying SF laws, to the Millennium and Millennium-II simulations, within the formalism developed by Neistein & Weinmann. Our best model includes lower SF efficiencies than predicted by the Kennicutt-Schmidt law at low stellar masses, no sharp threshold of cold gas mass for SF, and a SF law that is independent of cosmic time. These simple modifications result in a model that is more successful than current standard models in reproducing various properties of galaxies less massive than 10^{10}Msun. The improvements include a good match to the observed auto-correlation function of galaxies, an evolution of the stellar mass function from z=3 to z=0 similar to observations, and a better agreement with observed specific star formation rates. However, our modifications also lead to a dramatic over-prediction of the cold mass content of galaxies. This shows that finding a successful model may require fine-tuning of both star formation and supernovae feedback, as well as improvements on gas cooling, or perhaps the inclusion of a yet unknown process which efficiently heats or expels gas at high redshifts.

description: We examine how child maltreatment—including neglect, physical and sexual abuse, and other forms of maltreatment—is affected by parental economic circumstances. Using state‐level panel data on cases of maltreatment and numbers of children in foster care, we find that increases in the fractions of children with absent fathers and working mothers in a state are related to increases in many measures of maltreatment, as are increases in the share of families with two nonworking parents and those with incomes below 75% of the poverty line. Decreases in state welfare benefit levels are associated with increases in foster care placement.
