description: Literature related to education leadership, governance, and political science provide a legal and process understanding of the position of minister responsible for education, but lack detail related to how the phenomenon is experienced by those in the position. Using a hermeneutic phenomenological approach, I explored the experience of being a minister of education in a Canadian province and present a nuanced interpretation of the position. This inquiry examined the lived experience of 5 former ministers of education and provides a greater understanding of this important, complex, and challenging position through the lens of the emergent themes: changing identity, voicing identity, educating identity, and trusting identity. The study concludes with interpretations and implications of these experiences and demonstrates how issues such as anxiety, authority, and accountability play important roles in Canadian education.

description: Magnetic correlations in superconducting LiFeAs were studied by elastic and by inelastic neutron scattering experiments. There is no indication for static magnetic ordering but inelastic correlations appear at the incommensurate wave vector (0:5+-d 0:-+d 0) with d=0.07 slightly shifted from the commensurate ordering observed in other FeAs-based compounds. The incommensurate magnetic excitations respond to the opening of the superconducting gap by a transfer of spectral weight.

description: The experience of work stress is widespread and often associated with deleterious employee outcomes. However, researchers have found that some types of work stress are associated with beneficial employee outcomes. Hindrance stress, which is evoked by threatening aspects of a job, has consistently been related to negative outcomes. On the other hand, stress that emanates from opportunities for growth and gain (challenge), has been associated with positive outcomes. Little is known about the psychological mechanisms responsible for these effects. The purpose of this dissertation is extend previous empirical and theoretical work on the relationship between work stress and employee outcomes. To this end, a new model of stress was developed to investigate perceptions of Need-Supply (N-S) fit (the match between employee needs and organizational supplies) as an explanation (mediator) for the relationship between the experience of challenge and hindrance stress with several employee outcomes. In addition, job self-efficacy (beliefs about the ability to perform work related tasks) was proposed of moderate the mediated effect of challenge stress; self-esteem (an overall appraisal of self-worth) was proposed to moderate the mediated effect of hindrance stress. A full three-wave panel study was carried out using sample of full-time employees across a wide range of industries, located in a large Western Canadian City. Generally, the results of this study provided mixed support for perceptions N-S fit as a mediating mechanism linking stress to employee outcomes. The data failed to support lagged relationships of stress on perceptions of N-S fit. Some support was found for a model where the relationship between stress and perceptions of N-S fit happens in the same temporal space. The moderating effects of job self-efficacy and self-esteem failed to find support. Overall, the results suggest that perceptions of N-S fit and job attitudes are relatively stable and resistant to lagged relationships of stress over a six month time span. Theoretical implications, limitations, suggestions for suture research, and managerial implications are discussed.

We present results of our studies concerning the capability of the telescope in detecting/discovering galactic (steady point sources) and extragalactic, transient (Gamma Ray Bursts) high energy neutrino sources as well as measuring ultra high energy diffuse neutrino fluxes. The neutrino effective area and angular resolution are presented as a function of the neutrino energy, and the background event rate (atmospheric neutrinos and muons) is estimated. The discovery potential of the neutrino telescope is evaluated and the experimental time required for a significant discovery of potential neutrino emitters (known from their gamma ray emission, assumedly produced by hadronic interactions) is estimated. For the simulation we use the HOU Reconstruction & Simulation (HOURS) software package.

description: This discussion focused on the numerical study of a wake episode. The Weather Research and Forecasting model was used in a downscale mode. The current literature focuses the discussion on the adiabatic dynamics of atmospheric wakes. Changes in mountain height and consequently on its relation to the atmospheric inversion layer should explain the shift in wake regimes: from a 'strong-wake' to a 'weak-wake' scenario. Nevertheless, changes in SST variability can also induce similar regime shifts. Increase in evaporation, contributes to increase convection and thus to an uplift of the stratified atmospheric layer, above the critical height, with subsequent internal gravity wave activity.

description: We investigate the classical gravitational tests for the six-dimensional Kaluza-Klein model with spherical (of a radius $a$) compactification of the internal space. The model contains also a bare multidimensional cosmological constant $Λ_6$. The matter, which corresponds to this ansatz, can be simulated by a perfect fluid with the vacuum equation of state in the external space and an arbitrary equation of state with the parameter $ω_1$ in the internal space. For example, $ω_1=1$ and $ω_1=2$ correspond to the monopole two-forms and the Casimir effect, respectively. In the particular case $Λ_6=0$, the parameter $ω_1$ is also absent: $ω_1=0$. In the weak-field approximation, we perturb the background ansatz by a point-like mass. We demonstrate that in the case $ω_1>0$ the perturbed metric coefficients have the Yukawa type corrections with respect to the usual Newtonian gravitational potential. The inverse square law experiments restrict the parameters of the model: $a/\sqrt{ω_1}\lesssim 6\times10^{-3}\ {cm}$. Therefore, in the Solar system the parameterized post-Newtonian parameter $γ$ is equal to 1 with very high accuracy. Thus, our model satisfies the gravitational experiments (the deflection of light and the time delay of radar echoes) at the same level of accuracy as General Relativity. We demonstrate also that our background matter provides the stable compactification of the internal space in the case $ω_1>0$. However, if $ω_1=0$, then the parameterized post-Newtonian parameter $γ=1/3$, which strongly contradicts the observations.

description: Detailed uncertainty analysis on numerical flow simulation models preserving a robust and reliable model of oil and gas reservoir is often deterministic, cumbersome and expensive (manpower and time consuming). Presence of a high-dimensional data space consisting of a large number of operational and geological parameters impedes practical decision making and future performance prediction of oil and gas recovery processes. Thus, the rise of uncertainty-based reservoir development scenarios has provoked reservoir engineers to look for substitute modeling techniques that are capable of being re-evaluated numerous times to examine the impact of specific variables or probing a range of scenarios on production profiles. Static (well logs and core analyses) and dynamic (injection and production history) data sets existing within oil and gas companies are extremely valuable sources of information which can aid operators for a better future field development planning. Petroleum data-driven analytics workflow, which integrates a comprehensive petroleum data analysis and machine learning methods, suggest an attractive alternate for explicit models of the underlying process that can be instantaneously reassessed. The current study incorporates a systematic data analysis alongside with numerical flow simulations to create a comprehensive data set for different recovery processes such as SAGD, waterflooding, ploymerflooding, and etc. It also entails different characteristics labeling reservoir heterogeneities and key pertinent oil and gas recovery operational constraints. The collected big-data set will then be used to design data-driven models which can forecast production performance of different oil and gas recovery processes. This dissertation has developed and implemented algorithms for the development of novel data-driven models for CMG-CMOST AI 2017.10 version within Proxy Dashboard. This is the unique contribution of this thesis. The presented results and performance characteristics associated with data-driven models which can be re-evaluated much faster than explicit models of the underlying process highlight the great potential of this modeling approach to be integrated directly into most existing reservoir management routines. This research provides a viable tool to overcome challenges related to dynamic assessment of uncertainties during history matching of recovery processes and signifies the ability of data-driven analytics in future performance prediction of various oil and gas reservoirs.

description: The primary aim of this research was to identify the issues encountered by school administrators and teachers in implementing the voucher program. We identified administrative issues in terms of the release of vouchers or billing statements, providing resources, application, and processing of documents, and career guidance orientation. Meanwhile, we also investigated instructional issues to teach like strategies and techniques, student preparation, learning resources, curriculum enhancement, and teachers’ preparation and readiness. The research method for this study was a qualitative phenomenological approach that focused on describing the lived experiences of people. This study involved six school administrators and six teachers that belonged to private senior high schools in a province in Central Luzon, Philippines, during the school year 2018-2019. The results showed that the issues associated with implementing voucher programs among school administrators are: (a) delays in application and processing of documents, (b) lack of parents’ support and students’ active participation in career guidance orientation, (c) delays in the voucher’s release, and (d) difficulties in hiring qualified teachers and the keeping of teachers. Meanwhile, the common problems associated with implementing voucher among teachers are: (a) lack of preparedness among teachers, (b) congested curriculum competencies and idealistic outcome expectations, (c) job mismatch, traditional teaching, non-congruency between the teaching strategies and content, (d) innovative technological advancements issues, and (e) students are not competent. They can learn significant insights from the research-based propositions drawn from the study

description: This chapter gives a self-contained review of the how standard open quantum system Hamiltonians can be mapped analytically onto representations in which the environments appear as one dimensional harmonic chains with nearest neighbour interactions. This mapping, carried out rigorously using orthogonal polynomial theory, then allows the full evolution of the system and environment to be simulated using time-adaptive density matrix renormalisation group methods. With the combination of these two techniques, numerically-exact results can be obtained for dissipative quantum systems in the presence of arbitrarily complex environmental spectral functions, and the correlations and processes in the environment which drive the effectively irreversible dynamics of the reduced state of the quantum system can be explored in real time. The chain representation also reveals a number of universal features of harmonic environments characterised by a spectral density which are discussed here.

Structure of the continental Moho and Lithosphere-Asthenosphere Boundary: Insights from receiver-function analysis and numerical modelling

description: The Moho and lithosphere-asthenosphere boundary (LAB) are fundamental discontinuities in the Earth’s outermost layers. The structure of these features can be discerned using seismic methods, providing important insights into the tectonic history of a region. This thesis is focused on the structure of these discontinuities in and around cratons, which are large, coherent domains of Earth’s continental lithosphere that have attained long-term stability with little internal deformation. The receiver-function method is an approach that uses locally scattered waves to image discontinuity structure beneath a seismograph station. P-wave receiver functions (PRFs) are often used to study Moho characteristics. Here, synthetic PRFs are used to understand the nature of the Moho in different scenarios. This approach is applied to observations from EarthScope Transportable Array (TA) stations in the western U.S. within a region that exhibits a complex transition from the craton and the Cordillera. Beneath the Cordillera, a flat Moho is interpreted to reflect lower crustal channel flow, whereas beneath the North American craton the Moho exhibits greater structural relief. By definition, the LAB forms the lower boundary of a tectonic plate. Using geophysical imaging methods, the LAB is not as easily mapped as the Moho, leading to the use of various proxies, such as a boundary between layers with differing seismic anisotropy. In the upper mantle, seismic anisotropy is generated by lattice-preferred orientation of constituent minerals, especially olivine. A numerical-simulation approach is employed based on a self-consistent model that extends from the Earth’s surface to the mantle transition zone. Mantle flow is investigated by 3-D numerical solution of the boundary-value problem using a finite-element method. The flow velocity is converted to anisotropic elastic stiffness tensors to create an anisotropic model with 21 independent c ijkl parameter plus density. Teleseismic P and S wavefields are simulated using a finite-difference method to characterize mantle discontinuities. P and S wave receiver functions are computed using the synthetic waveforms to understand the effectiveness and limitations of these approaches for imaging the LAB. Anisotropy has a strong influence, due to change in S wave velocity in radial and transverse directions.

description: In hybrid models, which combine hydrodynamical and transport approaches to describe different stages of heavy-ion collisions, conversion of fluid to individual particles, particlization, is a non-trivial technical problem. We describe in detail how to find the particlization hypersurface in a 3+1 dimensional model, and how to sample the particle distributions evaluated using the Cooper-Frye procedure to create an ensemble of particles as an initial state for the transport stage. We also discuss the role and magnitude of the negative contributions in the Cooper-Frye procedure.

Measurement of the cross-section for b-jets produced in association with a Z boson at sqrt(s)=7 TeV with the ATLAS detector
Creators: name: ATLAS Collaboration

Year: 2011
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A measurement is presented of the cross-section for b-jet production in association with a Z boson in pp collisions at a centre-of-mass energy of sqrt(s)=7 TeV. The analysis uses the data sample collected by the ATLAS experiment in 2010, corresponding to an integrated luminosity of approximately 36 pb^-1. The event selection requires a Z boson decaying into high pt electrons or muons, and a b-jet, identified by its displaced vertex, with transverse momentum pt>25 GeV and rapidity |y|<2.1. After subtraction of backgrounds, the yield is extracted from the vertex mass distribution of the candidate b-jets. The ratio of this cross-section to the inclusive Z cross-section (the average number of b-jets per Z event) is also measured. Both results are found to be in good agreement with perturbative QCD predictions at next-to-leading order.

description: We propose a new inflationary scenario in type IIB Calabi-Yau compactifications, where the inflaton is a Kähler modulus parameterising the volume of an internal four-cycle. The inflaton potential is generated via poly-instanton corrections to the superpotential which give rise to a naturally flat direction due to their double exponential suppression. Given that the volume mode is kept stable during inflation, all the inflaton-dependent higher dimensional operators are suppressed. Moreover, string loop effects can be shown to be negligible throughout all the inflationary dynamics for natural values of the underlying parameters. The model is characterised by a reheating temperature of the order $T_{\rm rh}\simeq 10^6$ GeV which requires $N_e \simeq 54$ e-foldings of inflation. All the inflationary observables are compatible with current observations since the spectral index is $n_s \simeq 0.96$, while the tensor-to-scalar ratio is $r\simeq 10^{-5}$. The volume of the Calabi-Yau is of order $10^3$ in string units, corresponding to an inflationary scale around $10^{15}$ GeV

An Exploration of Hierarchy as Fractal in the Theology of Dionysios the Areopagite
Creators: name: Williams, Georgia J.
Publisher: name: Columbia University
Year: 2010
Subjects: Religion

description: Eric Perl, in his provocatively titled book, Theophany: The Neo-Platonic Philosophy of Dionysius the Areopagite, argues not only that Dionysios’ thought is thoroughly Neo-Platonic and fully compatible with Christianity, but that “the Dionysian doctrine of cosmic and ecclesiastical hierarchy is not only consistent with but essential to holy tradition” and that “Dionysius represents precisely those doctrines which are most typical of [Eastern] Orthodoxy in distinction from the west.” Like it or not, it is not that easy to ignore hierarchy in the sense the Areopagite had in mind in the Corpus Dionysiacum (CD). It is Dionysios who is credited with the first use of the word “hierarchy” as an abstract noun and the influence of this abstract notion of hierarchy has been far-reaching and is ubiquitous within society, not only within the Christian churches. Two related ideas continue to trouble me in the aftermath of reading Perl on Dionysios. The first is the thought that in our natural suspicion of hierarchy we may be sowing the very seeds that will keep us from ever being able to tap the wisdom of the CD. The second, is that if Perl – whose arguments are thorough, persuasive, and beautiful – is correct in both his understanding of neo-Platonic hierarchy and in his assertion that this is the thoroughgoing philosophical backdrop for the Areopagite, then hierarchy isn’t just a convenient construct dreamed up by churchmen that helps us get closer to God if we follow the rules of order, nor is it just a description of the functional workings of the mystical and sacramental life as understood within the Eastern ascetic tradition; though neither of those understandings would be wrong per se, both would be deficient. If Perl is right, Dionysios understood all creation to be Theophany, and hierarchy as the very structure of the entire created order, which reflects the life of God in existence. This hierarchy is not an “optional extra,” and opting out of participation – in so far as this is even possible – is, quite literally, to use the words of St. Paul (Rom 1:25), “exchanging the truth for a lie” and straightforwardly spells physical and spiritual death. For those of us with anarchist (or at least rebellious) tendencies – for those who have a developed sense of justice and despise hierarchical abuses – the news seems bad. If Perl is right, running away from Church structures won’t solve this problem because you can’t run away from the structure of existence itself. What exactly are we supposed to do? St. Symeon the New Theologian’s solution was to argue that the true bishop is the person with a pure heart (he had monastics in mind); but Dionysios’s fiery 8th Epistle to the monk Demophilos makes it more than clear that he does not see this as a possible solution for the very reason that hierarchical order is violated. Abolish the structure of reality we cannot. Nihilism doesn’t seem a very attractive option, so what are we left with?

description: Recent work on the connection between in-medium subthreshold $K^-N$ amplitudes and kaonic atom potentials is updated by using a next to leading order chirally motivated coupled channel separable interaction model that reproduces $\bar KN$ observables at low energies, including the very recent SIDDHARTA results for the atomic $K^-$-hydrogen $1s$ level shift and width. The corresponding $K^-$-nucleus potential is evaluated self-consistently within a single-nucleon approach and is critically reviewed with respect to empirical features of phenomenological optical potentials. The need to supplement the single-nucleon based approach with multi-nucleon interactions is demonstrated by showing that additional empirical absorptive and dispersive terms, beyond the reach of chirally motivated $K^-$-nucleus potentials, are required in order to achieve good agreement with the bulk of the data on kaonic atoms.

description: Distal enhancers play critical roles in sustaining oncogenic gene-expression programs. We identify aberrant enhancer-like activation of GGAA tandem repeats as a characteristic feature of B-cell acute lymphoblastic leukemia (B-ALL) with genetic defects of the ETV6 transcriptional repressor, including ETV6-RUNX1+ and ETV6-null B-ALL. We show that GGAA repeat enhancers are direct activators of previously identified ETV6-RUNX1+/- like B-ALL "signature" genes, including the likely leukemogenic driver EPOR. When restored to ETV6-deficient B-ALL cells, ETV6 directly binds to GGAA repeat enhancers, represses their acetylation, downregulates adjacent genes, and inhibits B-ALL growth. In ETV6-deficient B-ALL cells, we find that the ETS transcription factor ERG directly binds to GGAA microsatellite enhancers and is required for sustained activation of repeat enhancer-activated genes. Together, our findings reveal an epigenetic gatekeeper function of the ETV6 tumor suppressor gene and establish microsatellite enhancers as a key mechanism underlying the unique gene-expression program of ETV6-RUNX1+/- like B-ALL. SIGNIFICANCE: We find a unifying mechanism underlying a leukemia subtype-defining gene-expression signature that relies on repetitive elements with poor conservation between humans and rodents. The ability of ETV6 to antagonize promiscuous, nonphysiologic ERG activity may shed light on other roles of these key regulators in hematolymphoid development and human disease.

description: Applying Shannon decomposition can reshape sequential circuits and improve opportunities for retiming. Both Shannon decomposition and retiming only rely on limited information about combinational blocks (timing estimates), so both techniques are suitable for high-level synthesis. We describe an efficient algorithm to preprocess a circuit using Shannon decomposition to increase retiming efficacy. It assembles complex chains of Shannon decompositions while carefully avoiding parallel ones in order to limit the area overhead due to logic duplication. We compare a traditional retiming flow with the same flow augmented with our algorithm. Although our algorithm provides no improvement on half of our benchmarks, for the other half we obtain a 25% speed-up on average (7% to 61%), while only increasing area by 5% (3% to 12%).
Passion and coping : relationships with burnout and goal attainment in collegiate athletes

description: The stress process in sport can lead to a number of negative outcomes for athletes, including burnout and a failure to attain desired goals in sport (Gaudreau & Blondin, 2002; Hoar et al., 2006). Athletes can manage stress by coping, which involves various thoughts and actions (Lazarus, 1999). A person-related variable that may influence coping is the passion that athletes have for sport. Vallerand and colleagues (2003) proposed the dualistic model of passion (DMP), which differentiates between two forms of passion: harmonious (HP) and obsessive (OP). This research examined the relationship between passion and coping in sport, and tested if coping mediated the relationship between types of passion and both burnout and goal attainment. College- and university-level volleyball players (N = 239; female n = 126) participated in a prospective observational study involving two time points approximately 3 months apart. Measures assessing passion, coping style, burnout, and goal attainment were administered using paper and online questionnaires. Results indicated that burnout at time 2 was negatively associated with task-oriented coping and positively associated with both distraction- and disengagement-oriented coping, while change in burnout between time 1 and time 2 was positively associated with change in distraction- and disengagement-oriented coping. Analyses with both prospective data and change scores indicated that goal attainment was positively associated with task-oriented coping and negatively associated with disengagement-oriented coping. HP was negatively associated with burnout and positively associated with goal attainment, and mediation analyses revealed that disengagement-oriented coping mediated the relationship between HP and burnout, while both task- and disengagement-oriented coping mediated the relationship between HP and goal attainment. Prospective analyses revealed that OP at time 1 was unrelated to both burnout and goal attainment at time 2, but these relationships were suppressed by disengagement-oriented coping. Change in OP was positively associated with change in burnout, and this relationship was mediated by disengagement-oriented coping. Overall, these results highlight the role of coping, particularly disengagement-oriented coping, in the relationship between types of passion and both burnout and goal attainment, and provide insight into the relationship between passion and the stress process in sport.
