description: The University of British Columbia in Vancouver has 29 projects under construction as of April 2015, ranging from academic lands to public spaces (UBC Campus and Community Planning, 2015). Research has shown that built environments have both direct and indirect effects on psychological well-being and mental health, one of which is how crowding and elevated noise levels hoist psychological distress (Ewans, 2003). This study examines how built environments (e.g. social spaces, access to nature) influence the well-being of students at UBC. This research focuses on students’ preferences of UBC Food Services Cafes and assumes that students prefer spaces in which they feel good/comfortable (Van Kamp et al., 2003). Using a correlational study, we first surveyed 82 UBC students and asked them to identify a favourite, mediocre and an avoided cafe. The results showed preference levels to Stir it Up, Neville’s, and Sauder Exchange Cafe, respectively. Then, we measured a pre-selected combination of eight factors of the built environments in these spaces by interviewing 20 participants per selected site. We finally analyzed data to find a correlation between specific factors of the built environment and students’ preferences. We did not obtain statistically significant results regarding any of the eight factors, however we found a trend of preference for lighting, location, less crowding and reduced noise levels. Thus we suggest that UBC needs to make sure, for future construction of UBC Food Services Cafes, to build them in highly populated class locations that have great lighting and are spacious.

description: This dissertation evaluates three types of subsidy programs designed to aid low-income residential electricity customers. The three programs are a "lifeline" rate system, which extends a "lifeline" of 450 KWH per month of low-cost electricity to consumers for essential uses; a payments to suppliers program; and a price discount program. Using a telephone survey of nine hundred District of Columbia residents, the study employs a path analysis, calculations of income elasticities, and estimates of the number of poor and non-poor customers consuming above and below the lifeline breakpoint to evaluate the horizontal and vertical equity of the three programs. The path analysis utilizes twelve independent variables: appliance stock; insulation quality; conservation attitude; physical size of dwelling; number of persons home during the day; household size; age, sex, race, and education of billpayer; home ownership; and annual household income. The dependent variable is annual KWH consumption. The path analysis shows that the direct effect of income on KWH consumption is 0.225 (standardized beta weight), and the indirect effect is 0.105. The indirect effect is largely composed of causal paths from income to usage via appliance stock and physical size of dwelling. Rating the three programs in terms of vertical and horizontal equity shows that all programs have substantial drawbacks. Recommendations include the abolition of the lifeline and price discount programs, the alteration of the payments to suppliers program to include more program eligibles, and the changing of the payments to suppliers program into a direct cash grant program. The implications of the study for larger issues--such as the effect of consumer advocates on utility commission agenda setting and policy outputs, and the prospects for substantial deregulation--are also discussed.

description: High-brilliance synchrotron radiation sources have opened new avenues for X-ray polarization analysis that go far beyond conventional polarimetry in the optical domain. With linear X-ray polarizers in a crossed setting polarization extinction ratios down to 10$^{-10}$ can be achieved. This renders the method sensitive to probe tiniest optical anisotropies that would occur, for example, in strong-field QED due to vacuum birefringence and dichroism. Here we show that high-purity polarimetry can be employed to reveal electronic anisotropies in condensed matter systems with utmost sensitivity and spectral resolution. Taking CuO and La$_2$CuO$_4$ as benchmark systems, we present a full characterization of the polarization changes across the Cu K-absorption edge and their separation into dichroic and birefringent contributions. At diffraction-limited synchrotron radiation sources and X-ray lasers, where polarization extinction ratios of 10$^{-12}$ can be achieved, our method has the potential to assess birefringence and dichroism of the quantum vacuum in extreme electromagnetic fields.

description: Recent developments in blockchain technology have inspired innovative new designs in resilient distributed and database systems. At their core, these blockchain applications typically use Byzantine fault-tolerant consensus protocols to maintain a common state across all replicas, even if some replicas are faulty or malicious. Unfortunately, existing consensus protocols are not designed to deal with geo-scale deployments in which many replicas spread across a geographically large area participate in consensus. To address this, we present the Geo-Scale Byzantine FaultTolerant consensus protocol (GeoBFT). GeoBFT is designed for excellent scalability by using a topological-aware grouping of replicas in local clusters, by introducing parallelization of consensus at the local level, and by minimizing communication between clusters. To validate our vision of high-performance geo-scale resilient distributed systems, we implement GeoBFT in our efficient ResilientDB permissioned blockchain fabric. We show that GeoBFT is not only sound and provides great scalability, but also outperforms state-of-the-art consensus protocols by a factor of six in geo-scale deployments.

description: We describe a simple classroom demonstration of a fluid-dynamic instability. The demonstration requires only a bucket of water, a piece of string and some used tealeaves or coffee grounds. We argue that the mechanism for the instability, at least in its later stages, is two-dimensional barotropic (shear-flow) instability and we present evidence in support of this. We show results of an equivalent basic two-dimensional numerical non-linear model, which simulates behavior comparable to that observed in the bucket demonstration. Modified simulations show that the instability does not depend on the curvature of the domain, but rather on the velocity profile.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: One of the most controversial concepts in Marxism today is that of the Asiatic mode of production. The latter has been used to characterize the social formations of Asia, Africa, and pre-Columbian America. However, studies that connect theory with practice are still far from being realized. Marx's concepts which he developed for the capitalist mode of production are still applied to pre-capitalist modes of production without either criticism or re-examination, and more alarmingly, with revision. Thus, the present work aims at (1) narrowing the gap between theory and practice, (2) re-examining some of Marx's basic concepts, and (3) formulating a theory of the Asiatic mode of production. In doing so, this dissertation explores in some detail the origin, development, and current status of Marxist historiography in general and the Asiatic mode of production in particular. In the light of this, it examines the social history of pre-colonial North Africa, with an emphasis of Algeria. It outlines the theory of the Asiatic mode of production. Thereby, it suggests that human history cannot be presented as a single sequence of successive stages, each the necessary outcome of its predecessor. Rather, it suggests that the Asiatic mode of production is a stage in the historical development of human society. It evolved from the primitive-communal mode of production and constitutes a stage from which all more developed modes of production evolved, whether directly or through other stages.

description: Superconducting transition temperature is calculated for differently doped bilayer cuprates. Superexchange is assumed to be the dominating mechanism of high-temperature superconductivity, but the contribution from the phonon potential is not negligible, which qualitatively explains the observed weak isotopic effect. The calculated value 2$Δ_{max}/k_B T_C \simeq 4.5$ is close to the experiment in the case of optimum doping.

description: The Homestake result is about ~ 2 σlower than the Ar-production rate, Q_{Ar}, predicted by the LMA MSW solution of the solar neutrino problem. Also there is no apparent upturn of the energy spectrum (R \equiv N_{obs}/N_{SSM}) at low energies in SNO and Super-Kamiokande. Both these facts can be explained if a light, Δm^2_{01} ~ (0.2 - 2) \cdot 10^{-5} eV^2, sterile neutrino exists which mixes very weakly with active neutrinos: \sin^2 2α~ (10^{-5} - 10^{-3}). We perform both the analytical and numerical study of the conversion effects in the system of two active neutrinos with the LMA parameters and one weakly mixed sterile neutrino. The presence of sterile neutrino leads to a dip in the survival probability in the intermediate energy range E = (0.5 - 5) MeV thus suppressing the Be, or/and pep, CNO as well as B electron neutrino fluxes. Apart from diminishing Q_{Ar} it leads to decrease of the Ge-production rate and may lead to decrease of the BOREXINO signal and CC/NC ratio at SNO. Future studies of the solar neutrinos by SNO, SK, BOREXINO and KamLAND as well as by the new low energy experiments will allow us to check this possibility. We present a general analysis of modifications of the LMA energy profile due to mixing with new neutrino states.

The coefficient of determination (r2) is high 0.934 (adjusted r2 = 0.93; P < 0.0001; F1,22 = 310.4) of the resulting relationship (lnSUL = 3.31925 + 0.8883971[lnHHW]) allows us to estimate SUL for LACM 162445 as ~36 mm (star plotted at lnSUL = 3.58), based on humeral head width of 1.34 mm.

Kinetic theory and dynamic structure factor of a condensate in the random phase approximation

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We present the microscopic kinetic theory of a homogeneous dilute Bose condensed gas in the generalized random phase approximation (GRPA), which satisfies the following requirements: 1) the mass, momentum and energy conservation laws; 2) the H-theorem; 3) the superfluidity property and 4) the recovery of the Bogoliubov theory at zero temperature \cite{condenson}. In this approach, the condensate influences the binary collisional process between the two normal atoms, in the sense that their interaction force results from the mediation of a Bogoliubov collective excitation traveling throughout the condensate. Furthermore, as long as the Bose gas is stable, no collision happens between condensed and normal atoms. In this paper, we show how the kinetic theory in the GRPA allows to calculate the dynamic structure factor at finite temperature and when the normal and superfluid are in a relative motion. The obtained spectrum for this factor provides a prediction which, compared to the experimental results, allows to validate the GRPA. PACS numbers:03.75.Hh, 03.75.Kk, 05.30.-d

INDUSTRIALIZATION AND CLASS STRUCTURE IN ALGERIA
Creators: name: Bourouh, Chaoura
Publisher: name: American University
Year: 2023

description: This dissertation analyzes the relationship between industrialization and class in Algeria during the 1967-77 period. The purpose of the analysis is to show that while industrialization was initiated by specific classes in power, it, in fact, restructured these classes by establishing a new dominant class. The study analyzes the concept of class (defined in terms of control over economic ownership and possession) as applied to the Algerian industrial structure comprising the state and private sectors. It is argued that the two sectors are characterized by the same relations of production, capitalist relations, and that they are controlled by the same class: the industrial bourgeoisie. The approaches of dependency, noncapitalist path and state capitalism are rejected as inadequate in explaining the character of the Algerian social formation because they neglect the real class relations in the state and private sectors. It is argued instead that a newly formed dominant class, the industrial bourgeoisie, is leading a course of independent capitalist development.

We give examples of some circuits synthesized with this technique. A direct result that follows from the technique is a new way to convert any classical digital circuit to its classical reversible form.

description: When learning policies for robot control, the required real-world data is typically prohibitively expensive to acquire, so learning in simulation is a popular strategy. Unfortunately, such polices are often not transferable to the real world due to a mismatch between the simulation and reality, called 'reality gap'. Domain randomization methods tackle this problem by randomizing the physics simulator (source domain) during training according to a distribution over domain parameters in order to obtain more robust policies that are able to overcome the reality gap. Most domain randomization approaches sample the domain parameters from a fixed distribution. This solution is suboptimal in the context of sim-to-real transferability, since it yields policies that have been trained without explicitly optimizing for the reward on the real system (target domain). Additionally, a fixed distribution assumes there is prior knowledge about the uncertainty over the domain parameters. In this paper, we propose Bayesian Domain Randomization (BayRn), a black-box sim-to-real algorithm that solves tasks efficiently by adapting the domain parameter distribution during learning given sparse data from the real-world target domain. BayRn uses Bayesian optimization to search the space of source domain distribution parameters such that this leads to a policy which maximizes the real-word objective, allowing for adaptive distributions during policy optimization. We experimentally validate the proposed approach in sim-to-sim as well as in sim-to-real experiments, comparing against three baseline methods on two robotic tasks. Our results show that BayRn is able to perform sim-to-real transfer, while significantly reducing the required prior knowledge.

title: View mappings for query languages
Creators: name: Wong, Kam Chooi
Publisher: name: The Open University
Year: 1984

description: The problems of current use of query languages are looked at. One chief drawback is the undesirable requirement for end user familiarity with and knowledge of the underlying database structures, in order to retrieve data effectively. The approach adopted towards resolving this is by means of high-level view support, using unit view structures called perceived records. A prime concern of this thesis then, is the study of perceived record mappings from the database. A set of criteria for categorising and analysing the features of database mappings for end-user views is first developed. In addition, a classification of data structure transformations and data item transformations is also presented. The framework is general and is independent of a specific data model or database management system. Its usefulness is demonstrated by its application to the analysis of view transformations from recursive database structures to high-level, unit view structures. In addition, it serves as a basis for evaluating and comparing the mapping facilities in existing systems. Possible ways of specifying a suitable data model for the perceived record view concept are described. Following on, two general mapping techniques are discussed. This leads to a proposal for a mapping mechanism that supports the flexible derivation of complex perceived record views that can differ considerably from the source structures. The mechanism uses an intermediary canonical transform model. Description of how the transform model mechansim can be used in practical systems to derive perceived record views, is also presented. The feasibility of the ideas proposed are tested out by implementing an interactive software system for defining perceived record views. For this, a mapping definition language for perceived record derivation is first designed. The control system sets up the structures of the mapping definition language and prompts the End-User-Administrator to define and specify the mappings for a perceived record. Appraisals of both the proposed mapping mechanism and implementation are discussed. Examples of use of the interface system are included. The limitations of the implementation are pinpointed with suggestions for further improvements. Practical applications of the work and evaluation of the approach in the light of other existing approaches, are also discussed.

description: Rhombic cell analysis as outlined in the first paper of the present series is applied to samples of varying depths and liming luminosities of the IRAS/PSCz Catalogue. Numerical indices are introduced to summarize essential information. Because of the discrete nature of the anlaysis and of the space distribution of galaxies, the indices for a given sample must be regarded as each having an irreducible scatter. Despite the scatter, the mean indices show remarkable variations across the samples. The underlying factor for the variations is shown to be the limiting luminosity rather than the sampling depth. As samples of more and more luminous galaxies are considered over a range of some 2 magnitudes (a factor of some 50 in space density), the morpholgy of the filled and empty regions the galaxies define degrades steadily towards insignificance, and the degrading is faster for the filled than the empty region.

description: The dissertation is a sociological analysis of the industrial labor force in Iran. Specifically, it looks at the effects of the accumulation strategy of the Pahlavi state during the 1960s and 1970s upon the structure and contradictions of the urban industrial labor force. The study was prompted by an interest in the role of urban industrial workers in the 1978-79 Iranian Revolution. Industrial strikes, the formation of workers' councils, and a short-lived movement for workers' control are the salient features of the self-activity and self-organization of industrial workers between 1978 and 1981. Nonetheless, industrial workers were relatively late to arrive on the political scene and, after the Revolution, were subsumed under the program of the clerical rulers. This raises questions about the nature of Iranian modernization, and about the character of the industrial working class. The land reform, industrialization project, and the Third, Fourth and Fifth national development plans (1962-1977) are examined detail, particularly as they relate to labor markets and the development of the urban industrial labor force in Iran. The study demonstrates that while much progress was made in the development of modern industry, and that urban industrial labor came to have a strategic role in the economy and the society, what had emerged during the period under consideration was a dual labor market and a young and differentiated industrial labor force, with implications for political and ideological practices during the Revolution.

We show that this ensemble implementation of the DJ algorithm is at best as efficient as the classical random algorithm. As soon as any attempt is made to classify all possible functions with certainty, the implementation requires an exponentially large number of molecules. The discrepancies arise out of the interpretation of mixed state density matrices.

description: We discuss the degree of spin polarization of single top quarks produced via $Wg$ fusion process in $ep$ collision at TESLA+HERAp and CLIC+LHC energies $\sqrt{s}=1.6$ and 5.3 TeV. For $eb \to t \barν$ subprocess we show that the top quark spin is completely polarized when the spin basis is chosen in the direction of the incoming positron beam in the rest frame of top quark. A description on how to combine the cross sections of $e^{+}b\to t\barν$ and $e^{+}g\to t\bar{b}\barν$ processes is given. $e^{+}$-beam direction is taken to be the favorite top quark spin decomposition axis in its rest frame and it is found to be comparable with the ones in $pp$ collision. It is argued that theoretical simplicity and experimental clearness are the advantage of $ep$ collision.

description: The nearly 200 species of direct-developing frogs in the genus Eleutherodactylus (the Caribbean Landfrogs that include the coquís) comprise an important lineage for understanding the evolution and historical biogeography of the Caribbean. Time-calibrated molecular phylogenies provide indirect evidence for the processes that shaped the modern anuran fauna, but there is little direct evidence from the fossil record of Caribbean frogs about their distributions in the past. We report a distal humerus of a frog from the Oligocene (approx. 29 Ma) of Puerto Rico that represents the earliest known fossil frog from any Caribbean island. Based on its prominent rounded distal humeral head and reduced ectepicondyle, we refer it to the genus Eleutherodactylus. This fossil provides additional support for an early arrival of some groups of terrestrial vertebrates to the Greater Antilles and corroborates previous estimates based on molecular phylogenies suggesting that this diverse Caribbean lineage was present in the islands by the mid-Cenozoic.
LIFE EXPERIENCES AND LOAD STRESS AS EACH RELATE TO RISK TAKING BY A SAMPLE OF LAW ENFORCEMENT OFFICERS

Publisher: name: American University

description: The purpose of this study was to ascertain the relationship of recent life-experience stress and load stress to risk-taking. Life-experience stress was identified by the Life-Experiences Survey (LES); load stress was induced by the Streufert Video Task (SVT) and risk-taking was measured by the subject's response to the SVT. The one hundred sixty male volunteers were law enforcement officers attending the Federal Bureau of Investigation National Academy (FBINA). The hypotheses tested posited that: (1) subjects exposed to high load stress--high speed level and high task level on the SVT--would take more risks than subjects exposed to low load stress--low speed and low task levels; (2) subjects with negative LES scores would take more risks than subjects with positive LES scores; and, (3) subjects with negative LES scores would take more risks at high load levels while subjects with positive LES scores would show no differences across load stress levels. The data were analyzed with a 2 x 2 x 2 analysis of variance (ANOVA), with fixed effects, after the homogeneity of variance assumption had been tested and found nonsignificant using the F(,max) procedure. The risk-taking score--the dependent variable--was measured in such a way that a score of one indicated maximum risk and a score of five indicated low risk. The results showed that subjects with negative LES scores took more risks than subjects with positive LES scores, and that subjects who were exposed to higher load stress on the SVT took more risks. The results were not significant for the third hypothesis. This last result could have occurred because a boundary problem existed with the SVT: subjects were limited in the amount of risk they were able to take before they failed. Additional analysis was done on a second dependent variable--called collisions--which was the number of times subjects took the maximum amount of risk and then failed at the task. The results of the additional analysis showed that while subjects with negative LES scores took greater risks than subjects with positive LES scores, they did not fail at a greater rate.

description: In a world of digitization, optical character recognition holds the automation to written history. Optical character recognition system basically converts printed images into editable texts for better storage and usability. To be completely functional, the system needs to go through some crucial methods such as pre-processing and segmentation. Pre-processing helps printed data to be noise free and gets rid of skewness efficiently whereas segmentation helps the image fragment into line, word and character precisely for better conversion. These steps hold the door to better accuracy and consistent results for a printed image to be ready for conversion. Our proposed algorithm is able to segment characters both from ideal and non-ideal cases of scanned or captured images giving a sustainable outcome.

description: This paper analyzes production, hedging, and speculative decisions when both futures and options can be used in an expected utility model of price and basis uncertainty. When futures and option prices are unbiased optimal hedging requires only futures (options are redundant). Options are used together with futures as speculative tools when market prices are perceived as biased. Straddles are used to speculate on beliefs about price volatility and to hedge the futures position used to speculate on beliefs about the expected value of the futures price. Mean-variance analysis in general is not consistent with expected utility when options are allowed.

description: We introduce the notion of Ricci-corrected differentiation in parabolic geometry, which is a modification of covariant differentiation with better transformation properties. This enables us to simplify the explicit formulae for standard invariant operators given in work of Cap, Slovak and Soucek, and at the same time extend these formulae from the context of AHS structures (which include conformal and projective structures) to the more general class of all parabolic structures (including CR structures).
