description: Se realizo un estudio de corte transversal para estudiar la presencia del síndrome de Burnout en el Hospital Escuela Oscar Danilo Rosales Arguello (HEODRA) de la ciudad de León, Nicaragua, en el año 2007. La población de estudio estuvo constituida por un total de 65 médicos y 100 del personal de enfermería. Se presentaron el doble de casos en el personal de enfermería que en los médicos. La dinámica de trabajo fue el factor mas percibido como desfavorable. La relación antigüedad laboral-casos tuvo comportamiento inverso, entre el personal de enfermería, a mas años labores mas casos, y lo contrario entre los médicos. La mayor parte de casos son jóvenes y se encuentran casados. Los casos predominantes en el personal de enfermería fueron del sexo femenino, en los médicos fue el masculino. Se recomienda buscar la equidad en la distribución de los horarios y trato interpersonal. Promover y mantener en forma permanente sistemas de evaluación del personal, y crear grupos terapéuticos de contención emocional dirigidos a todos el personal de trabajo, con el fin de promover mayor solidaridad, diálogo y respeto por las opiniones de los otros, mejorando los canales de comunicación entre los compañeros de trabajo.

description: The black hole uniqueness and the no-hair theorems imply that the quasinormal spectrum of any astrophysical black hole is determined solely by its mass and spin. The countably infinite number of quasinormal modes of a Kerr black hole are thus related to each other and any deviations from these relations provide a strong hint for physics beyond the general theory of relativity. To test the no-hair theorem using ringdown signals, it is necessary to detect at least two quasinormal modes. In particular, one can detect the fundamental mode along with a subdominant overtone or with another angular mode, depending on the mass ratio and the spins of the progenitor binary. Also in the light of the recent discovery of GW190412, studying how the mass ratio affects the prospect of black hole spectroscopy using overtones or angular modes is pertinent, and this is the major focus of our study. First, we provide ready-to-use fits for the amplitudes and phases of both the angular modes and overtones as a function of mass ratio $q\in[0,10]$. Using these fits we estimate the minimum signal-to-noise ratio for detectability, resolvability, and measurability of subdominant modes/tones. We find that performing black-hole spectroscopy with angular modes is preferable when the binary mass ratio is larger than $q\approx 1.2$ (provided that the source is not located at a particularly disfavoured inclination angle). For nonspinning, equal-mass binary black holes, the overtones seem to be the only viable option to perform a spectroscopy test of the no-hair theorem. However this would require a large ringdown signal-to-noise ratio ($\approx 100$ for a $5\%$ accuracy test with two overtones) and the inclusion of more than one overtone to reduce modelling errors, making black-hole spectroscopy with overtones impractical in the near future.

description: El VIH/SIDA es un problema creciente en Nicaragua, particularmente en el occidente del país. Un estudio descriptivo de corte transversal fue realizado para identificar la seroprevalencia de VIH/SIDA y las conductas de riesgo en trabajadoras sexuales y conductores de transporte pesados que circulan por el by pass de León. La muestra estuvo comprendida por 100 personas. Los participantes después de firmar un consentimiento informado por escrito se les llenó una ficha epidemiológica y se les tomó una muestra sanguínea para ser sometida a la prueba de VIH. L a seroprevalencia de VIH/SIDA fue 1% en conductores de transporte pesado, las conductas de riesgo más importantes fueron: no uso de preservativos, frecuencia de I.T.S. y número de compañeros sexuales. Las trabajadoras sexuales se realizan la prueba de VIH/SIDA más frecuentemente que los conductores de transporte pesado. Se concluye que de cada 50 conductores de transporte pesado que circulan por el área del by pass de León, al menos uno puede estar positivo al VIH y que las trabajadoras sexuales hacen mejor uso de la medidas preventivas para VIH/Sida.

description: A large number of secondary electrons with low energies (< 20 eV) is produced during irradiation of biological matter. It is known that such electrons lead to fragmentation of DNA via dissociative electron attachment (DEA). DEA happens via the formation of a resonance (transient negative ion). Studying the properties of the resonances (energy and lifetime) is the first step to describe and understand DEA. Although isolated DNA constituents have been studied broadly, DEA is likely to be affected by the environment. The goal of this research is a theoretical investigation of the influence of the environment on resonance formation. The object of this study is low-energy collision with pyridine (prototype of biological molecule) and thymine (one of the DNA nucleobases), both in gas-phase and surrounded by water (forming small clusters). We provide a comparison of pyridine and pyridine-H2O calculations for various standard scattering models (Static Exchange, Static Exchange plus Polarization and Close-Coupling). For pyridine-(H2O)n' n = 2, 3, 5, calculations have been performed using the Static Exchange method, whereas thymine and thymine-(H2O)n' n = 2, 3, 5, were studied using the Static Exchange and Static Exchange plus Polarization methods. This research gives an insight into how the water environment changes resonance properties. The presence of water does not have the same effects in all systems studied. We confirmed that the effects depend on the character of water as a proton donor or acceptor. We showed that the resonance shift depends on the water binding site to the molecule and that it does not shift all resonances in one system equally strongly. Additionally, isolated pyridine has been investigated in more detail, in order to compare it with diazines, studied previously in our group. We found that the resonance formation in both system is similar.

description: In2O3 is an n-type transparent semiconducting oxide possessing a surface electron accumulation layer (SEAL) like several other relevant semiconductors, such as InAs, InN, SnO2, and ZnO. Even though the SEAL is within the core of the application of In2O3 in conductometric gas sensors, a consistent set of transport properties of this two-dimensional electron gas (2DEG) is missing in the present literature. To this end, we investigate high quality single-crystalline as well as textured doped and undoped In2O3(111) films grown by plasma-assisted molecular beam epitaxy to extract transport properties of the SEAL by means of Hall effect measurements at room temperature while controlling the oxygen adsorbate coverage via illumination. The resulting sheet electron concentration and mobility of the SEAL are 1.5E13 cm^-2 and 150 cm^2/Vs, respectively, both of which get strongly reduced by oxygen-related surface adsorbates from the ambient air. Our transport measurements further demonstrate a systematic reduction of the SEAL by doping In2O3 with the deep compensating bulk acceptors Ni or Mg. This finding is supported by X-ray photoelectron spectroscopy measurements of the surface band bending and SEAL electron emission. Quantitative analyses of these XPS results using self-consistent, coupled Schroedinger-Poisson calculations indicate the simultaneous formation of compensating bulk donor defects (likely oxygen vacancies) which almost completely compensate the bulk acceptors. Finally, an enhancement of the thermopower by reduced dimensionality is demonstrated in In2O3: Seebeck coefficient measurements of the surface 2DEG with partially reduced sheet electron concentrations between 3E12 and 7E12 cm^-2 (corresponding average volume electron concentration between 1E19 and 2E19 cm^-3 indicate a value enhanced by 80% compared to that of bulk Sn-doped In2O3 with comparable volume electron concentration.

At the fixed lattice spacing of 0.1 fm the lightest sea quark mass used is a third of the strange quark mass. A comparison is made between heavy-light chiral perturbation theory and the f_B^(static) decay constant. The mass of the bottom quark is also reported: m_b(m_b) = 4.25(2)(11) GeV, where the first error is statistical and the last error is the systematic uncertainty.

description: El presente trabajo tiene como principal objetivo estimar la incertidumbre en la determinación de aflatoxina B1 en una muestra de maní de exportación por Cromatografía Líquida de Alto Desempeño con Detector de Fluorescencia (HPLC-FD). El cálculo se basó en el procedimiento general establecido en las guías para la expresión de la incertidumbre GUM ISO 1995 y EURACHEM/CITAC. Se identificaron 18 variables del modelo matemático que influyen en la incertidumbre del contenido de aflatoxina B1 en la muestra de maní. El valor de la incertidumbre combinada, calculada por la ley de propagación de la incertidumbre, fue de 0.224632 y el contenido de aflatoxina B1 fue de 1.47ng/g. Se evaluaron los índices de contribución de cada variable a la incertidumbre combinada y se demostró a través del diagrama de Pareto, que solamente cinco variables son las que influyen significativamente en la incertidumbre de los resultados, calculándose un valor de 0.223492. El intervalo de confianza para una muestra de maní fue (1.47 ± 0.45)ng/g para un factor de cobertura de 2 al 95.45% de nivel de confianza. La incertidumbre estándar relativa, calculada con la máxima precisión, fue de 15%, siendo aceptable a los niveles de concentración del presente estudio.

description: One desired capability for machines is the ability to transfer their knowledge of one domain to another where data is (usually) scarce. Despite ample adaptation of transfer learning in various deep learning applications, we yet do not understand what enables a successful transfer and which part of the network is responsible for that. In this paper, we provide new tools and analyses to address these fundamental questions. Through a series of analyses on transferring to block-shuffled images, we separate the effect of feature reuse from learning low-level statistics of data and show that some benefit of transfer learning comes from the latter. We present that when training from pre-trained weights, the model stays in the same basin in the loss landscape and different instances of such model are similar in feature space and close in parameter space.

description: Primary and secondary education is a crucial stage to build a strong foundation before diving deep into specialised subjects in colleges and universities. To excel in the current education system, students are required to have a deep understanding of knowledge according to standardized curriculums and syllabus, and exam-related problem solving skills. In current school settings, this learning normally occurs in large classes of 30-40 students per class. Such a ``one size fits all'' approach may not be effective, as different students proceed on their learning in different ways and pace. To address this problem, we propose the Self-Evolving Adaptive Learning (SEAL) system for personalized education at scale.

description: We review the connection between noncommutative field theories and gravity. When the noncommutativity is induced by the Moyal product we can use the Seiberg-Witten map in order to deal with ordinary fields. We then show that the effect of the noncommutativity is the same as a field dependent gravitational background. The gravitational background is that of a gravitational plane wave and the coupling is charge dependent. Uncharged fields couple more strongly than the charged ones. Deviations from the usual dispersion relations are discussed and we show that they are also charge dependent.

Unemployment insurance’s labour market impacts
Creators: name: Shen, Kailing
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines Unemployment Insurance’s (UI) labour market impacts, focusing on the contingent, temporary natures of UI benefit. Using the Survey of Labour and Income Dynamics , the results suggest UI significantly affects both individuals’ employment/unemployment transitions and their job match quality. Chapter 2 presents a historical development of the UI program in Canada; a survey of related literature; and, finally, a theoretical analysis of how contingent, temporary UI benefit coverage could affect labour market dynamics. Chapter 3 empirically examines UI’s impacts on individuals’ employment/unemployment cycles. The two major findings are: (1) UI’s minimum employment requirement is found to delay employment separation in the seasonal sector; and, (2) the availability of UI benefits is found to postpone reemployment in both the seasonal and non-seasonal sectors. Overall, simulation results suggest that without those delays, the national unemployment rate could be 16% lower (e.g. lowered from 7.6% to 6.6%) in the late 1990s. Simulation results also imply that, with the exception of the experience rating rules and the divisor rule, the 1996 Employment Insurance (EI) reform did not have a significant impacts [sic] on the national unemployment rate. Chapter 4 empirically examines UI’s impacts on individuals’ reemployment wages. The random effect model it uses takes account of the endogeneity of both individuals’ employment/unemployment durations and their initial wages. Furthermore, the empirical specification allows UI benefits to have time-varying impacts. The results suggest, overall, that UI coverage increases unemployed workers’ reemployment wages by about 9.5%.

Nach Betrachtung von Vorbildern aus der Geschichte, aus anderen Bereichen menschlichen Schaffens und Produzierens, sowie der Analyse derzeitiger Vorfertigungsverfahren wird der Schluss gezogen, dass ein großes theoretisches Potential zur Optimierung der angewandten Prozesse vorliegt. Im weiteren wird ein prototypischer Modellprozess entwickelt mit dem Ziel ein architektonisches Artefakt zu produzieren. Zur Verwendung für die automatisierte Produktion von Architektur wird zunächst eine dreiachsige CNC Fräse gebaut. Die Möglichkeiten dieser Maschine stellen gleichzeitig die Grenzen für die weitere Entwicklung des Modellprozesses dar. Dieser wird nun vorangetrieben durch die Erstellung von physischen Prototypen. Auf der Basis von Erkenntnissen die aus dem Bau Selbiger gezogen werden, wird schließlich ein Algorithmus erstellt. Mit dessen Hilfe wird zum Abschluss dieser Erkundung ein architektonisches Artefakt zur Veranschaulichung des entwickelten Architekturschaffensprozesses gebaut.
description: This thesis engages opportunities for the automisation of architectural creation. After an investigation into historic archetypes and scrutiny of other areas of human efffort and creation as well as an analysis of current prefabrication processes the conclusion is drawn that there looms a great theoretical potential for the optimization of the currently applied processes. In the following a prototypical model process is developed aiming at the production of an architectural artefact. Initially a three axis CNC router is built as a tool for the automated fabrication of architecture within this work. This machine-s abilities- limitations represent the constraints imposed on the following development of the model process which is now advanced. The creation of physical prototypes is used to close in on the realization of potentials for improvement of the current processes. Finally, on the basis of this newly gained knowledge an algorithm is created. This algorithm is used for the creation of an architectural artefact which serves as a demonstration of the developed process for architectural creation and marks the end of this endeavor.

description: The footprint of radio emission from extensive air showers is known to exhibit asymmetries due to the superposition of geomagnetic and charge-excess radiation. For inclined air showers a geometric early-late effect disturbs the signal distribution further. Correcting CoREAS simulations for these asymmetries reveals an additional disturbance in the signal distribution of highly inclined showers in atmospheres with a realistic refractive index profile. This additional apparent asymmetry in fact arises from a systematic displacement of the radio-emission footprint with respect to the Monte-Carlo shower impact point on the ground. We find a displacement of $\sim 1500\,\text{m}$ in the ground plane for showers with a zenith angle of $85^\circ$, illustrating that the effect is relevant in practical applications. A model describing this displacement by refraction in the atmosphere based on Snell's law yields good agreement with our observations from CoREAS simulations. We thus conclude that the displacement is caused by refraction in the atmosphere.

title: Self-Directed Learning of Experienced Adult Online Learners Enrolled in FutureLearn MOOCs
Creators: name: de Waard, Inge
Publisher: name: The Open University
Year: 2017

description: This research resulted in a conceptual framework describing the actual learning components influencing the learning experience of informal, adult learners engaged in FutureLearn courses. The conceptual framework consists of five learning components: individual & social learning, context, technology and media elements, organising learning, and learner characteristics. These five learning components are driven by two enablers or inhibitors of learning: motivation and learning goals. For adult informal learners, motivation is mostly intrinsic, and learning goals are mostly personal. This research investigated the informal learning of 56 adult learners with prior online experience, engaging in individual and/or social self-directed learning using any device to follow a FutureLearn course. Literature from MOOCs, mobile and informal learning provides scientific support, in addition to literature clarifying the rationale for choosing self-directed learning compared to similar learning concepts (self-regulated, self-determined and self-managed learning). The participants of this study voluntarily followed one of three FutureLearn courses that were rolled out for the first time by the end of 2014. Data were collected at three different stages: an online survey (pre-course), self-reported learning logs (during the course), and semi-structured one-on-one interviews (post-course). The data were analysed using Charmaz’s (2014) method for constructing a grounded theory. The analysis included memo-writing, and involved open coding, line-by-line coding, and focused coding in order to construct a grounded theory that provided insights into the self-directed learning experiences of FutureLearn participants. By getting a better understanding of the self-directed learning in FutureLearn courses, additional insights are gained to enhance informal learning, instructional design, and to contextualize and personalise learning within FutureLearn courses to create an increasingly meaningful learning experience.

description: We present an analysis of the quantum adiabatic algorithm for solving hard instances of 3-SAT (an NP-complete problem) in terms of Random Matrix Theory (RMT). We determine the global regularity of the spectral fluctuations of the instantaneous Hamiltonians encountered during the interpolation between the starting Hamiltonians and the ones whose ground states encode the solutions to the computational problems of interest. At each interpolation point, we quantify the degree of regularity of the average spectral distribution via its Brody parameter, a measure that distinguishes regular (i.e., Poissonian) from chaotic (i.e., Wigner-type) distributions of normalized nearest-neighbor spacings. We find that for hard problem instances, i.e., those having a critical ratio of clauses to variables, the spectral fluctuations typically become irregular across a contiguous region of the interpolation parameter, while the spectrum is regular for easy instances. Within the hard region, RMT may be applied to obtain a mathematical model of the probability of avoided level crossings and concomitant failure rate of the adiabatic algorithm due to non-adiabatic Landau-Zener type transitions. Our model predicts that if the interpolation is performed at a uniform rate, the average failure rate of the quantum adiabatic algorithm, when averaged over hard problem instances, scales exponentially with increasing problem size.

description: We discuss the notion of a large field cutoff for lattice gauge models with compact groups. We propose and compare gauge invariant and gauge dependent (in the Landau gauge) criteria to sort the configurations into ``large-field'' and ``small-field'' configurations. We show that the correlations between volume average of field size indicators and the behavior of the tail of the distribution are very different in the gauge and scalar cases. We show that the effect of discarding the large field configurations on the plaquette average is very different above, below and near beta=5.6 for a pure SU(3) LGT.

description: A model for the evolution of ultrarelativistic heavy-ion collisions at both CERN SPS and RHIC top energies is presented. Based on the assumption of thermalization and a parametrization of the space-time expansion of the produced matter, this model is able to describe a large set of observables including hadronic momentum spectra, correlations and abundancies, the emission of real photons, dilepton radiation and the suppression pattern of charmonia. Each of these obervables provides unique capabilities to study the reaction dynamics and taken together they form a strong and consistent picture of the evolving system. Based on the emission of hard photons measured at SPS, we argue that a strongly interacting, hot and dense system with temperatures above 250 MeV has to be created early in the reaction. Such a system is bound to be different from hadronic matter and likely to be a quark-gluon plasma, and we find that this assumption is in line with the subsequent evolution of the system that is reflected in other observables.

description: We have examined the performance of the analytic Hartree-Fock-Slater (HFS) method for various alpha (Slater's exchange parameter) values and empiricaly determined the optimal alpha value by minimizing the mean absolute error (MAE) in atomization energies of the G2 set of molecules. At the optimal alpha the HFS method's performance is far superior with the MAE of 14 kcal/mol than that of the local density approximation (MAE ~ 36 kcal/mol) or the Hartree-Fock theory (MAE ~ 78 kcal/mol). The HFS exchange functional with alpha = 0.7091 is found to perform significantly better than the Kohn-Sham exchange functional for equally weighted atoms H-Kr. We speculate that use of this alpha value may be useful in parametrization of empirical exchange-correlation functionals.

Black Holes From the Dark Ages: Exploring the Reionization Era and Early Structure Formation With Quasars and Gamma-Ray Bursts

description: The cosmic reionization era, which includes formation of the first stars, galaxies, and AGN, is now one of the most active frontiers of cosmological research. We review briefly our current understanding of the early structure formation, and use the ideas about a joint formation of massive black holes (which power the early QSOs) and their host galaxies to employ high-redshift QSOs as probes of the early galaxy formation and primordial large-scale structure. There is a growing evidence for a strong biasing in the formation of the first luminous sources, which would lead to a clumpy reionization. Absorption spectroscopy of QSOs at z > 6 indicates the end of the reionization era at z ~ 6; yet measurements from the WMAP satellite suggest and early reionization at z ~ 10 - 20. The first generation of massive stars, perhaps aided by the early mini-quasars, may have reionized the universe at such high redshifts, but their feedback may have disrupted the subsequent star and galaxy formation, leading to an extended and perhaps multimodal reionization history ending by z ~ 6. Observations of gamma-ray bursts from the death events of these putative Population III stars may provide essential insight into the primordial structure formation, reionization, early chemical enrichment, and formation of seed black holes which may grow to become central engines of luminous quasars.

G₂ DNA damage checkpoint : inhibitors and there potential for anticancer treatment
Creators: name: Sturgeon, Christopher Michael
Publisher: name: University of British Columbia
Year: 2010

description: In response to DNA damage, cell survival can be enhanced by activation of DNA repair mechanisms and of checkpoints that delay cell cycle progression to allow more time for DNA repair. G₂ checkpoint inhibitors can force cells arrested in G₂ phase by DNA damage to enter mitosis thereby enhancing the killing of cancer cells by DNA-damaging approaches. Checkpoint inhibitors represent a promising class of therapeutic agents in the treatment of cancer. The goals of my research were to (i) characterize novel checkpoint inhibitors in terms of their therapeutic potential and, if possible, mode of action, (ii) increase the therapeutic properties of checkpoint inhibitors by combining them with DNA repair inhibitors, and (iii) develop a therapeutic use of the checkpoint inhibitor, isogranulatimide. Two novel checkpoint inhibitors were psilostachyin and cryptofolione. The target of psilostachyin may be Wee1, a kinase which inhibits CDK1. Cryptofolione shares structural and biological properties with leptomycin B, a highly specific inhibitor of Crm1-mediated nuclear export. This suggests nuclear export inhibition may be a novel means to achieve checkpoint inhibition. Inhibiting both repair and the checkpoint with drugs might cause cancer cells to undergo cell division in the presence of lethal amounts of un-repaired DNA. However, interfering with DNA repair via inhibition of DNA-dependent protein kinase (DNA-PK) reduces the ability of checkpoint inhibitors to abrogate G₂ arrest, as well as their radio sensitizing activity. Components of the checkpoint pathway were highly over-activated in this situation. This suggests that combining checkpoint inhibition with targeted DNA repair inhibition may not be therapeutically viable. Varying the time of addition of checkpoint inhibitors following DNA damage revealed that G₂ checkpoint abrogation alone is insufficient for radio sensitization. Instead, checkpoint inhibitors must be present for the duration of S-phase progression to achieve radio sensitization. Taken together, these studies describe the search for and development of checkpoint inhibitors, ideally for future therapeutic use. These results have relevance to the development of G₂ checkpoint inhibitors as experimental therapeutic approaches to the treatment of cancer. This research represents a major step forward in the pre-clinical development of checkpoint inhibitors as anticancer agents.

description: To read the final version please go to IEEE TGRS on IEEE Xplore. Convolutional neural networks (CNNs) have been attracting increasing attention in hyperspectral (HS) image classification, owing to their ability to capture spatial-spectral feature representations. Nevertheless, their ability in modeling relations between samples remains limited. Beyond the limitations of grid sampling, graph convolutional networks (GCNs) have been recently proposed and successfully applied in irregular (or non-grid) data representation and analysis. In this paper, we thoroughly investigate CNNs and GCNs (qualitatively and quantitatively) in terms of HS image classification. Due to the construction of the adjacency matrix on all the data, traditional GCNs usually suffer from a huge computational cost, particularly in large-scale remote sensing (RS) problems. To this end, we develop a new mini-batch GCN (called miniGCN hereinafter) which allows to train large-scale GCNs in a mini-batch fashion. More significantly, our miniGCN is capable of inferring out-of-sample data without re-training networks and improving classification performance. Furthermore, as CNNs and GCNs can extract different types of HS features, an intuitive solution to break the performance bottleneck of a single model is to fuse them. Since miniGCNs can perform batch-wise network training (enabling the combination of CNNs and GCNs) we explore three fusion strategies: additive fusion, element-wise multiplicative fusion, and concatenation fusion to measure the obtained performance gain. Extensive experiments, conducted on three HS datasets, demonstrate the advantages of miniGCNs over GCNs and the superiority of the tested fusion strategies with regards to the single CNN or GCN models. The codes of this work will be available at https://github.com/danfenghong/IEEE_TGRS_GCN for the sake of reproducibility.
