An exploratory study of the relationships among hospital sub-cultures, job involvement, upward striving, organizational commitment, and job satisfaction
Creators: name: Hawkes, Elizabeth Lawrence
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this exploratory study was to investigate whether there is any relationship between the strength of the culture in a hospital work group and the job involvement, upward striving, organizational commitment and job satisfaction of the employees within that work group. The conceptual framework for this study is the symbolic frame of reference for understanding organizational behaviour. The concept is described by Bolman and Deal (1984). Two hospitals participated in the study, which provided two data sets. Subjects were employees of certain departments within each of the hospitals. Each subject completed a four-part questionnaire. The first part collected demographic data, part two contained questions on job involvement, upward striving, and organizational commitment, part three focussed on job satisfaction, and part four was the culture strength scale. The culture strength scales were developed separately at each hospital and, therefore, contained items which were relevant to a specific facility. There were two major findings from the study. First, there is a positive relationship between job satisfaction and culture strength. Results at both hospitals were consistent in this regard. No relationships were found between job involvement, upward striving, and/or organizational commitment with culture strength. The second finding was that at the larger hospital there was a significant difference in culture strength scores among some work units, while at the smaller hospital this was not the case. This finding supports the idea that size of an organization is a factor in the predisposition to subculture formation.

description: The complexity of financial markets arise from the strategic interactions among agents trading stocks, which manifest in the form of vibrant correlation patterns among stock prices. Over the past few decades, complex financial markets have often been represented as networks whose interacting pairs of nodes are stocks, connected by edges that signify the correlation strengths. However, we often have interactions that occur in groups of three or more nodes, and these cannot be described simply by pairwise interactions but we also need to take the relations between these interactions into account. Only recently, researchers have started devoting attention to the higher-order architecture of complex financial systems, that can significantly enhance our ability to estimate systemic risk as well as measure the robustness of financial systems in terms of market efficiency. Geometry-inspired network measures, such as the Ollivier–Ricci curvature and Forman–Ricci curvature, can be used to capture the network fragility and continuously monitor financial dynamics. Here, we explore the utility of such discrete Ricci curvatures in characterizing the structure of financial systems, and further, evaluate them as generic indicators of the market instability. For this purpose, we examine the daily returns from a set of stocks comprising the USA S&P-500 and the Japanese Nikkei-225 over a 32-year period, and monitor the changes in the edge-centric network curvatures. We find that the different geometric measures capture well the system-level features of the market and hence we can distinguish between the normal or ‘business-as-usual’ periods and all the major market crashes. This can be very useful in strategic designing of financial systems and regulating the markets in order to tackle financial instabilities.

description: The aim of the present thesis is to explore the development of metacognition and computational thinking skills in Educational Robotics activities. Initially, the thesis introduces a didactic model which sets rules and conditions for creating favorable and efficient learning conditions in EP activities. The model is called CPGC +, after Collaboration, Problem, Game, and Competition, while "+" stands for supplementary teachers’ supportive interventions which aim to promote students' skills such as computational thinking, metacognitive and problem solving skills. The dissertation then presents research results exploring techniques for guiding and supporting students to develop metacognition and computational thinking skills. In particular, it focuses on the role of guidance (strong or minimal) and on the modality of the response to the prompting questions (written, selection or discussion) as well as on the role of the students' age and gender. The positive results of the research suggest that, in the framework of the CPGC+ model and with the appropriate support and guidance techniques, Educational Robotics can be a dynamic learning tool that supports the development of students' skills, irrespective of their age and gender. In addition, incorporating prompts for written answers or for choosing the right answer, positively affects the development of their skills.

subject: FOS: Physical sciences

description: The two-dimensional Hubbard model on the square lattice is studied in the presence of lattice distortions in the adiabatic approximation. The self energy is computed within perturbation theory up to second order, which provides a way for studying the quasiparticle dispersion. We compute numerically the second order contribution to the self-energy using a standard Fast Fourier Transform Algorithm for finite system sizes. The stability of the lattice distortions is investigated and a schematic phase diagram is drawn. The Fermi surface is analyzed for densities near to half filling, the presence of lattice distortion change some spectral properties of the model and gives an anisotropic interacting FS. The spectral function is calculated along several lines in momentum space and the renormalized quasiparticle dispersion is obtained. The behavior of the density of states is shown for different values of the intrasite repulsion U in the different phases.

description: The objective of this thesis is the reconsideration of the practices of personal adornment during the Neolithic period in Greece, through the assemblage, extensive bibliographic documentation, and critical evaluation of all the available data derived from more than a hundred excavated sites –an archaeological archive of wide geographical and chronological scope. In addition, a thorough study of the ornament corpus from the Middle/Late Neolithic lakeside settlement of Dispilio in Kastoria was conducted.The anthropological and archaeological literature on theoretical and methodological issues concerning practices of personal adornment is presented first. Then follows the examination of technologies and processes of production, consumption, recycling, deposition, and diffusion; as well as the investigation of social correlates of personal adornment, as they are reflected in the choice of different raw materials (shell, clay, bone, stone, and metal) and ornament types (beads, pendants, and bracelets) across Neolithic Greece.

Measuring and Evaluating the Security Level of Circuits Slides and Transcript

Abstract: When we design for low power, we estimate the power consumption at design time and measure it after fabrication and before we submit it to ISSCC. The same must be done with the security evaluation of a circuit: it should be estimated at design time, and measured after fabrication. It is however difficult to measure security. Therefore, in this tutorial, we plan to show how to perform the security evaluation for different classes of circuits: true random number generators, physically unclonable functions and side-channel evaluation of cryptographic implementations. When designing a true random number generator, statistical tests on the output data are not sufficient: important in this context are the NIST standards SP800-90B and the German BSI AIS20/31 standards to evaluate true randomness. In the context of physically unclonable functions, established standards do not exist yet: here it is important to evaluate how much is the total cost to generate a full-entropy key. When evaluating the resistance to side-channel and fault attacks, it is important to describe the set-up of the experiments. If not, the only conclusion one can make is that the circuit resists an evaluation with the given set-up.

description: Most work on scholarly document processing assumes that the information processed is trustworthy and factually correct. However, this is not always the case. There are two core challenges, which should be addressed: 1) ensuring that scientific publications are credible -- e.g. that claims are not made without supporting evidence, and that all relevant supporting evidence is provided; and 2) that scientific findings are not misrepresented, distorted or outright misreported when communicated by journalists or the general public. I will present some first steps towards addressing these problems and outline remaining challenges.

description: We investigate the possibility of boiling instability of nuclear liquid in the inner core of the proto-neutron star formed in the core collapse of a type II supernova. We derive a simple criterion for boiling to occur. Using this criterion for one of best described equations of state of supernova matter, we find that boiling is quite possible under the conditions realized inside the proto-neutron star. We discuss consequences of this process such as the increase of heat transfer rate and pressure in the boiling region. We expect that taking this effect into account in the conventional neutrino-driven delayed-shock mechanism of type II supernova explosions can increase the explosion energy and reduce the mass of the neutron-star remnant.

ISSCC Short Course Slides
This discussion of processor global clocking starts with on-chip transmission-line effects, and the design and tuning of standard trees, including power, clock gating, and useful skew. Most high-performance processors use more specialized methods including clock spines and meshes, which require special timing methods, but can have significant advantages with respect to skew, robustness, and design closure. The design of resonant meshes with mode-changing capabilities are discussed. The final topic is clock sensors and control loops to improve power and performance including useful jitter.

description: The sanitary situation due to the COVID-19 impacted the everyday life of populations on a worldwide scale. Here we focus on students following the French education system and their daily habits during the months of November and December - the second confinement. The increase of exposure to screens, low social interaction, and physical inactivity are known to impact sleeping quality. We explored their effects on students' sleeping quality during this exceptional period with 4 surveys conducted on a sample of 18 students in higher education. Our sample was composed of 12 female and 6 male participants over 18 years old. Our data analysis supports that sleeping quality is negatively affected by stress, but positively and strongly correlated with socialization. Surprisingly, our data analysis does not support a correlation between screen time and sleeping quality. This project could further be disseminated at a bigger scale in France and abroad, thus becoming an international project that could have an impact on better understanding how students’ lifestyle and sleep have been affected over the lockdowns.  - A school project during Open Science Class (Master AIRE, CRI - Université de Paris)

description: World currency network constitutes one of the most complex structures that is associated with the contemporary civilization. On a way towards quantifying its characteristics we study the cross correlations in changes of the daily foreign exchange rates within the basket of 60 currencies in the period December 1998 -- May 2005. Such a dynamics turns out to predominantly involve one outstanding eigenvalue of the correlation matrix. The magnitude of this eigenvalue depends however crucially on which currency is used as a base currency for the remaining ones. Most prominent it looks from the perspective of a peripheral currency. This largest eigenvalue is seen to systematically decrease and thus the structure of correlations becomes more heterogeneous, when more significant currencies are used as reference. An extreme case in this later respect is the USD in the period considered. Besides providing further insight into subtle nature of complexity, these observations point to a formal procedure that in general can be used for practical purposes of measuring the relative currencies significance on various time horizons.

description: SAR (Synthetic Aperture Radar) tomography reconstructs 3-D volumes from stacks of SAR images. High-resolution satellites such as TerraSAR-X provide images that can be combined to produce 3-D models. In urban areas, sparsity priors are generally enforced during the tomographic inversion process in order to retrieve the location of scatterers seen within a given radar resolution cell. However, such priors often miss parts of the urban surfaces. Those missing parts are typically regions of flat areas such as ground or rooftops. This paper introduces a surface segmentation algorithm based on the computation of the optimal cut in a flow network. This segmentation process can be included within the 3-D reconstruction framework in order to improve the recovery of urban surfaces. Illustrations on a TerraSAR-X tomographic dataset demonstrate the potential of the approach to produce a 3-D model of urban surfaces such as ground, façades and rooftops.

description: The sequential quantum random access code (QRAC) allows two or more decoders to obtain a desired message with higher success probability than the best classical bounds by appropriately modulating the measurement sharpness. Here, we propose an entanglement-assisted sequential QRAC protocol which can enable device-independent tasks. By relaxing the equal sharpness and mutually unbiased measurement limits, we widen the sharpness modulation region from a one-dimensional interval to a two-dimensional triangle. Then, we demonstrate our scheme experimentally and get more than 27 standard deviations above the classical bound even when both decoders perform approximately projective measurements. We use the observed success probability to quantify the connection among sequential QRAC, measurement sharpness, measurement biasedness, and measurement incompatibility. Finally, we show that our protocol can be applied to sequential device-independent randomness expansion and our measurement strategy can enhance the success probability of decoding the entire input string. Our results may promote a deeper understanding of the relationship among quantum correlation, quantum measurement, and quantum information processing.

description: The computation of vibrational spectra of diatomic molecules through the exact diagonalization of algebraically determined matrixes based on powers of Morse coordinates is made substantially more efficient by choosing a properly adapted quantum-mechanical basis, specifically tuned to the molecular potential. A substantial improvement is achieved while still retaining the full advantage of the simplicity and numerical light-weightedness of an algebraic approach. In the scheme we propose, the basis is parameterized by two quantities which can be adjusted to best suit the molecular potential through a simple minimization procedure.

description: The synergy of GLAST and the proposed EXIST mission as the Black Hole Finder Probe in the Beyond Einstein Program is remarkable. With its full-sky per orbit hard X-ray imaging (3-600 keV) and "nuFnu" sensitivity comparable to GLAST, EXIST could measure variability and spectra of Blazars in the hard X-ray synchrotron component simultaneous with GLAST (~10-100GeV) measures of the inverse Compton component, thereby uniquely constraining intrinsic source spectra and allowing measured high energy spectral breaks to measure the cosmic diffuse extra-galactic background light (EBL) by determining the intervening diffuse IR photon field required to yield the observed break from photon-photon absorption. Such studies also constrain the physics of jets (and parameters and indeed the validity of SSC models) and the origin of the >100 MeV gamma-ray diffuse background likely arising from Blazars and jet-dominated sources. An overview of the EXIST mission, which could fly in the GLAST era, is given together with a synopsis of other key synergies of GLAST-EXIST science.

description: The usage of ground-mounted photovoltaic solar panels is increasing, and it is essential to fully understand the wind behavior and loading on the panels, since there is no specific code or guideline for their design in the present. In addition, the University of Ottawa and Carleton University recently developed a new facility, called the Wind Damage Simulator (WDS). This study will allow to understand the flow behavior in the facility, along with the effects of different blower rpm settings on the flow. A CFD study was also conducted, in order to examine the methodology and turbulence models suitable for the flow replicated in this facility, for future research. The newly developed Wind Damage Simulator (WDS) facility was used to examine wind-induced effects on two solar panels attached to a frame. The mean pressure coefficient distribution on the photovoltaic panels was examined for several wind angles of incidence (AOI) and wind speeds. The wind AOI considered were the 0°, 30°, 45°, 180°, 210° and 225°, along with wind speeds ranging from 14 m/s to 42 m/s, with increments of around 2 m/s. The experimental results showed fluctuations in the Cp distribution on the panels, due to the WDS wind flow being highly unstable. The 180° wind AOI led to the highest uplift mean Cp equivalent (Cpeq) value on the panels. The 45° and 180° wind AOI were found to induce a Cpeq of significantly higher magnitude on the first panel compared to the second panel, whereas the 0° and 210° wind AOI induced a significantly higher Cpeq magnitude on the second panel compared to the first panel Cpeq. Moreover, the CFD study provided pressure coefficient distribution on the panels and flow visualization when interacting with the panels surfaces. The LES Dynamic Smagorinsky subgrid scale model was found to be more suitable for the WDS numerical replication than the RANS shear stress transport k-ω turbulence model. The LES model showed the fluctuating pressure coefficients on the panels’ surfaces, induced by the swirls that were formed post interaction of the wind with the panels.

description: A prespecified set of genes may be enriched, to varying degrees, for genes that have altered expression levels relative to two or more states of a cell. Knowing the enrichment of gene sets defined by functional categories, such as gene ontology (GO) annotations, is valuable for analyzing the biological signals in microarray expression data. A common approach to measuring enrichment is by cross-classifying genes according to membership in a functional category and membership on a selected list of significantly altered genes. A small Fisher's exact test $p$-value, for example, in this $2\times2$ table is indicative of enrichment. Other category analysis methods retain the quantitative gene-level scores and measure significance by referring a category-level statistic to a permutation distribution associated with the original differential expression problem. We describe a class of random-set scoring methods that measure distinct components of the enrichment signal. The class includes Fisher's test based on selected genes and also tests that average gene-level evidence across the category. Averaging and selection methods are compared empirically using Affymetrix data on expression in nasopharyngeal cancer tissue, and theoretically using a location model of differential expression. We find that each method has a domain of superiority in the state space of enrichment problems, and that both methods have benefits in practice. Our analysis also addresses two problems related to multiple-category inference, namely, that equally enriched categories are not detected with equal probability if they are of different sizes, and also that there is dependence among category statistics owing to shared genes. Random-set enrichment calculations do not require Monte Carlo for implementation. They are made available in the R package allez.

description: We simulate the collapse of isolated dwarf galaxies using SPH + N-Body simulations including a physically motivated description of the effects of supernova feedback. As the gas collapses and stars form, the supernova feedback disrupts enough gas to temporarily quench star formation. The gas flows outward into a hot halo, where it cools until star formation can continue once more and the cycle repeats. The star formation histories of isolated Local Group dwarf galaxies exhibit similar episodic bursts of star formation. We examine the mass dependence of the stellar velocity dispersions and find that they are no less than half the velocity of the halos measured at the virial radius.

A comparative study of the swelling and mechanical properties of vertebrate elastins
Creators: name: Chalmers, Gavin William Geddes
Publisher: name: University of British Columbia
Year: 2010

description: The swelling-temperature compensation hypothesis as proposed by Gosline and French (1979) is examined by investigating the physical and mechanical properties of an evolutionary series of vertebrate elastins. Temperature-dependent swelling, low water contents and thermodynamics typical of hydrophobic systems were observed for all elastins except salmon. Salmon elastin, on the other hand, showed temperature-independent swelling and a high water content. Thermodynamic analysis showed that salmon elastin still contained a hydrophobic component. The swelling-temperature compensation hypothesis suggests that the extreme hydrophobic nature of elastin evolved in order to provide the proteins with temperature-dependent swelling and thus, maintaining elastic efficiency over a wide temperature range. All elastins should then be very hydrophobic systems which is inconsistent with the physical chemical results. All vertebrate elastins are not necessarily hydrophobic systems since salmon elastin shows no temperature-dependence to its swelling. The efficiency of a series of vertebrate elastins was measured over 0 to 60°C temperature range using a forced vibration technique. Over a wide frequency range, both lower and higher vertebrate elastins were capable of efficient spring-like behaviour. Both a higher vertebrate, with temperature-dependent swelling, and a lower vertebrate, with no temperaturate-dependence to its swelling, showed elastic efficiency. The swelling-temperature compensation hypothesis must be rejected.

description: Upcoming searches for lepton flavour change (LFV) aim to probe New Physics(NP) scales up to $ \sim 10^4$ TeV, implying that they will be sensitive to NP at lower scales that is suppressed by loops or small couplings. We suppose that the NP responsable for LFV is beyond the reach of the LHC and can be parametrised in Effective Field Theory, introduce a small power-counting parameter à la Cabibbo-Wolfenstein, and assess whether the existing dimension six operator basis and one-loop RGEs provide a good approximation for LFV. We find that mu to e flavour-changing observables can be sensitive to a few dozen dimension eight operators, and to some effects of two-loop anomalous dimensions, for NP scales below 20-100 TeV. We also explore the effect of some simplifying assumptions in the one-loop RGEs, such as neglecting flavour-changing effects.

description: Quantum multipartite entangled states play significant roles in quantum information processing. By using difference schemes and orthogonal partitions, we construct a series of infinite classes of irredundant mixed orthogonal arrays (IrMOAs) and thus provide positive answers to two open problems. The first is the extension of the method for constructing homogeneous systems from orthogonal arrays (OAs) to heterogeneous multipartite systems with different individual levels. The second is the existence of $k$-uniform states in heterogeneous quantum systems. We present explicit constructions of two and three-uniform states for arbitrary heterogeneous multipartite systems with coprime individual levels, and characterize the entangled states in heterogeneous systems consisting of subsystems with nonprime power dimensions as well. Moreover, we obtain infinite classes of $k$-uniform states for heterogeneous multipartite systems for any $k\geq2$. The non-existence of a class of IrMOAs is also proved.

Analysis of ordered categorical data
Creators: name: Chang, Janis
Publisher: name: University of British Columbia
Year: 2010

description: Methods of testing for a location shift between two populations in a longitudinal study are investigated when the data of interest are ordered, categorical and non-linear. A non-standard analysis involving modelling of data over time with transition probability matrices is discussed. Next, the relative efficiencies of statistics more frequently used for the analysis of such categorical data at a single time point are examined. The Wilcoxon rank sum, McCullagh, and 2 sample t statistic are compared for the analysis of such cross sectional data using simulation and efficacy calculations. Simulation techniques are then utilized in comparing the stratified Wilcoxon, McCullagh and chi squared-type statistic in their efficiencies at detecting a location shift when the data are examined over two time points. The distribution of a chi squared-type statistic based on the simple contingency table constructed by merely noting whether a subject improved, stayed the same or deteriorated is derived. Applications of these methods and results to a data set of Multiple Sclerosis patients, some of whom were treated with interferon and some of whom received a placebo are provided throughout the thesis and our findings are summarized in the last Chapter.
