A grounded theory study of the experience of spirituality among persons living with schizophrenia
Creators: name: Tarko, Michel Andre
Publisher: name: University of British Columbia
Year: 2009

description: Spirituality in the discipline of nursing has gained popularity over the past two decades. National and provincial nursing associations and colleges expect nurses to be educated in providing spiritual health assessments and interventions in order to provide holistic nursing care. There is a paucity of research in the nursing literature on the meaning of spirituality from the perspectives of individuals who experience chronic mental illness, specifically schizophrenia. Spirituality remains an elusive construct, challenging psychiatric nurse educators, researchers and practitioners in the development of nursing curricula to guide psychiatric nursing practice. The focus of this research study was to develop a substantive theory about the experience of spirituality among individuals living with schizophrenia using grounded theory methodology in the tradition of Glaser and Strauss (1967). Forty semi-structured interviews and four focus groups were conducted with 20 participants who self-reported to be diagnosed with schizophrenia. Findings: The substantive theory "spirituality as connection" indicates that spirituality for persons living with schizophrenia involves a dialectical process in which one strives to be connected to one's spiritual self (body-mind-spirit), significant others (family, friends, G o d / Higher Power, health care professionals), community (others living with a mental illness, others who are well, a faith community, the community in which participants lived), and nature, while at the same time experiencing situations and incidents that promote disconnection from these sub-themes. Strategies used by participants to achieve connection included: taking prescribed atypical anti-psychotic medications, maintaining their health and a healthy lifestyle, use of prayer / meditation, caring for self and others, and engaging in creative activities that added meaning to their life experiences. Among the 17 factors contributing to connection, exemplars are: reconnecting with one's spirit through prayer and meditation, attending drop-in centres for persons living with a mental illness, and walking / hiking in nature. Outcomes include feeling peaceful, love, contentment, being accepted and nurtured by others. Among the 14 factors contributing to disconnection, exemplars are: the effect of the illness on relationships with other people, the stigma of being in a psychiatric ward, being unemployed, and taking typical antipsychotic medications. Outcomes include feeling powerlessness, isolation, rejection and alienation.

description: Forecast distributions based on historical yields and subjective expectations for 1987 expected crop yields were compared for 90 Western Kentucky grain farms. Different subjective probability elicitation techniques were also compared. In many individual cases, results indicate large differences between subjective and empirical moments. Overall, farmer expectations for 1987 corn yields were below those predicted from their past yields, while soybean expectations were above the historical forecast. Geographical location plays a larger role than crop in comparisons of relative variability of yield. Neither elicitation technique nor manager characteristics have significant effects on the comparisons of the forecasts.

description: We examine the properties of two-dimensional conformal field theories (CFTs) with vanishing central charge based on the extended Kac-table for c_(9,6)=0 using a general ansatz for the stress energy tensor residing in a Jordan cell of rank two. Within this setup we will derive the OPEs and two point functions of the stress energy tensor T(z) and its logarithmic partner field t(z) and illustrate this by a bosonic field realization. We will show why our approach may be more promising than those chosen in the literature so far, including a discussion on properties of the augmented minimal model with vanishing central charge such as full conformal invariance of the vacuum as a state in an irreducible representation, consequences on percolation from null vectors and the structure of representations within the Kac table. Furthermore we will present another solution to the c --> 0 catastrophe based on an logarithmic CFT tensor model. As example, we consider a tensor product of the well-known c=-2 logarithmic CFT with a four-fold Ising model. We give an overview of the possible configurations and various consequences on the two point functions and the OPEs of the stress energy tensor T(z) and its logarithmic partner field t(z). We will motivate that due to the full conformal invariance of the vacuum at c=0, we have to assume a Jordan cell for the identity since t(z) is now a descendant of a new h=0 field.

description: Applied general equilibrium modelling represents a powerful tool for assessing future likely economic changes due to upcoming or hypothesised policy shocks such as those brought about by EU enlargement. It entails the main advantage of considering the complex simultaneous linkages, interactions and feedback effects between various sectors, institutions and factor resources within an economy, as well as the inter- and intra-industry trade links with other economies across the globe. This technical paper develops a general equilibrium model applied to Romania (GEMAR) with an emphasis on the agricultural and food processing activities. A simple simulation example is then given for illustrative purposes. More extensive use of GEMAR will be made in other forthcoming papers where the model will be employed to identify those economic impacts stemming from incorporating Romania's agricultural and food sectors into EU/CAP structures. The model is static with constant returns to scale and perfect competition in production. Other studies have deployed modelling techniques to deal with EU accession issues. However, the literature assessing separately the economic effects of CAP enlargement for Romania is extremely sparse. In addition, as far as the authors are aware of, there are no studies that solely focused on the likely economic effects of CAP enlargement on Romanian agricultural and food processing sectors at a disaggregated level and within a single-country general equilibrium framework. Hence, the paper should not only fill in a gap in the modelling literature dealing with EU's next phase of eastward expansion but also tackle an issue of current interest for both researchers and policy-makers involved in agriculture and economic development.

description: The observed cross sections for $e^+e^-\rightarrow μ^+μ^-$ at energies from 3.8 to 4.6 GeV are measured using data samples taken with the BESIII detector operated at the BEPCII collider. We measure the muonic widths and determine the branching fractions of the charmonium states $ψ(4040)$, $ψ(4160)$, and $ψ(4415)$ decaying to $μ^+μ^-$, as well as making a first determination of the phase of the amplitudes. In addition, we observe evidence for a structure in the dimuon cross section near 4.220 GeV/$c^2$, which we denote as $S(4220)$. Analyzing a coherent sum of amplitudes yields eight solutions, one of which gives a mass of ${M}_{S(4220)}=4216.7 \pm 8.9 \pm 4.1$~MeV/$c^2$, a total width of ${\rm Γ^{\rm tot}_{S(4220)}}=47.2 \pm 22.8 \pm 10.5$~MeV, and a muonic width of ${\rm Γ}^{μμ}_{S(4220)}=1.53\pm1.26\pm0.54$~keV, where the first uncertainties are statistical and the second systematic. The eight solutions give the central values of the mass, total width, muonic width to be, respectively, in the range from 4212.8 to 4219.4 MeV/$c^2$, from 36.4 to 49.6 MeV, and from 1.09 to 1.53 keV. The statistical significance of the $S(4220)$ signal is $3.9σ$. Correcting the total dimuon cross section for radiative effects yields a statistical significance for this structure of more than $7σ$.

Upper Limits on the Extragalactic Background Light from the Gamma-Ray Spectra of Blazars

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The direct measurement of the extragalactic background light (EBL) is difficult at optical to infrared wavelengths because of the strong foreground radiation originating in the Solar System. Very high energy (VHE, E$>$100 GeV) gamma rays interact with EBL photons of these wavelengths through pair production. In this work, the available VHE spectra from six blazars are used to place upper limits on the EBL. These blazars have been detected over a range of redshifts and a steepening of the spectral index is observed with increasing source distance. This can be interpreted as absorption by the EBL. In general, knowledge of the intrinsic source spectrum is necessary to determine the density of the intervening EBL. Motivated by the observed spectral steepening with redshift, upper limits on the EBL are derived by assuming that the intrinsic spectra of the six blazars are $\propto E^{-1.8}$. Upper limits are then placed on the EBL flux at discrete energies without assuming a specific spectral shape for the EBL. This is an advantage over other methods since the EBL spectrum is uncertain.

description: The role of the feedback effect on physical reservoir computing is studied theoretically by solving the vortex-core dynamics in a nanostructured ferromagnet. Although the spin-transfer torque due to the feedback current makes the vortex dynamics complex, it is clarified that the feedback effect does not always contribute to the enhancement of the memory function in a physical reservoir. The memory function, characterized by the correlation coefficient between the input data and the dynamical response of the vortex core, becomes large when the delay time of the feedback current is not an integral multiple of the pulse width. On the other hand, the memory function remains small when the delay time is an integral multiple of the pulse width. As a result, a periodic behavior for the short-term memory capacity is observed with respect to the delay time, the phenomenon of which can be attributed to correlations between the virtual neurons via the feedback current.

Is the subdominant part of the energy spectrum due to downscale energy cascade hidden in quasi-geostrophic turbulence?

description: In systems governing two-dimensional turbulence, surface quasi-geostrophic turbulence, (more generally $α$-turbulence), two-layer quasi-geostrophic turbulence, etc., there often exist two conservative quadratic quantities, one ``energy''-like and one ``enstrophy''-like. In a finite inertial range there are in general two spectral fluxes, one associated with each conserved quantity. We derive here an inequality comparing the relative magnitudes of the ``energy'' and ``enstrophy'' fluxes for finite or infinitesimal dissipations, and for hyper or hypo viscosities. When this inequality is satisfied, as is the case of 2D turbulence,where the energy flux contribution to the energy spectrum is small, the subdominant part will be effectively hidden. In sQG turbulence, it is shown that the opposite is true: the downscale energy flux becomes the dominant contribution to the energy spectrum. A combination of these two behaviors appears to be the case in 2-layer QG turbulence, depending on the baroclinicity of the system.

How Useful are Computable General Equilibrium Models for Sustainability Impact Assessment

Year: 2005
Subjects: Environmental Economics and Policy

description: Computable general equilibrium (CGE) modelling represents a powerful tool for hypothesising possible sustainability outcomes that might be triggered with the implementation of policy proposals. Nevertheless, CGE modelling is based on several tight general equilibrium and neoclassical micro-economic theoretical assumptions that make their application to the assessment of all three pillars of sustainability questionable. Although some of these assumptions have been relaxed in recent and more advanced CGE models, further research needs to be undertaken in order to bring model specifications closer to realistic behavioural relationships. CGE models also tend to focus on alternative equilibrium outcomes and rarely deal with the adjustment process or regulation measures needed to realistically bring the economy into the desired new equilibrium stance. Moreover, CGE models inherently face severe rigidities when attempting to deal with environmental and social effects. However, some authors have argued that CGE modelling may provide a suitable backbone for all three dimensions of Sustainability Impact Assessment (SIA). The paper takes a critical stand and supports the view that though CGE models may provide some useful information on individual, particularly economic, impact aspects of policy reforms, it may be inappropriate and even misleading to rely extensively on their use in SIAs.

description: Due to limited resources for conservation purposes, conservation efforts are often directed towards better explored/known, and more charismatic species (mostly mammals or birds), leaving other species, especially invertebrates, unprotected, or poorly protected. In order to point out the importance of hoverfly conservation, based on long- term monitoring data for Serbia, Vujić et al. (2016), identified key species and core areas significant for their survival in this region. The aim of this study was to designate species which need to be included in the list of protected and strictly protected species of hoverflies in Serbia, based on the new records from recent field work. According to our results, 11 species will be suggested for future protection: Chrysotoxum montanum Nedeljković & Vujić, 2015, Chrysotoxum orthostylum Vujić, 2015, Chrysotoxum tomentosum Giglio- Tos, 1890, Doros destillatorius Mik 1885, Eumerus banaticus in litt., Eumerus pannonicus Ricarte, Vujić & Radenković, 2016, Merodon calidus in litt., Merodon illyricus in litt., Merodon austerus Vujić & Radenković, 2017, Merodon moesiacus in litt., Merodon rasicus Vujić & Radenković, 2015. Additionally, for the specified species with enough occurrence points, species distribution models were created using maxent function within dismo R software package in order to determine the suitable climatic habitats for these species. Results of this study can significantly contribute to planning future monitoring activities and creating conservation strategies for the preservation of important hoverfly species in Serbia.

description: In the next few years, smart farming will reach each and every nook of the world. The prospects of using unmanned aerial vehicles (UAV) for smart farming are immense. However, the cost and the ease in controlling UAVs for smart farming might play an important role for motivating farmers to use UAVs in farming. Mostly, UAVs are controlled by remote controllers using radio waves. There are several technologies such as WiFi or ZigBee that are also used for controlling UAVs. However, Smart Bluetooth (also referred to as Bluetooth Low Energy) is a wireless technology used to transfer data over short distances. Bluetooth smart is cheaper than other technologies and has the advantage of being available on every smart phone. Farmers can use any smart phone to operate their respective UAVs along with Bluetooth Smart enabled agricultural sensors in the future. However, certain requirements and challenges need to be addressed before UAVs can be operated for smart agriculture-related applications. Hence, in this article, an attempt has been made to explore the types of sensors suitable for smart farming, potential requirements and challenges for operating UAVs in smart agriculture. We have also identified the future applications of using UAVs in smart farming.

description: Sustainability Impact Assessment (SIA) is an increasingly accepted form of strategic impact assessment, and has recently been adopted, for example, as the preferred method of ex ante policy assessment in the European Community. A methodology for SIA for application to international trade policy measures was developed by IDPM in 1999, and since then has been used in conducting an ongoing SIA study of the WTO trade negotiations agenda. This paper will review the past four years' experience in carrying out SIA of trade policy, and will identify the main difficulties and challenges that have arisen in its application. The main lessons for the further development of the methodology will then be discussed.

description: Our study assesses the impacts of different policy reforms, such as domestic trade liberalisation, implementation of WTO agreements in the textile sector and WTO negotiations on the movement of natural persons, and examines their welfare and poverty implications at the household level in the economy of Bangladesh. We use a comparative static computable general equilibrium (CGE) model based on the 1995-96 Social Accounting Matrix (SAM) of the Bangladesh economy. This study carries out three simulations. The first simulation entails full liberalisation of tariffs and the resultant reduction in government revenues are mobilised by enhancing the existing production taxes and imposing new taxes on construction sector; in the second simulation, export of ready-made garments (RMG) are reduced by 25 percent; and in the third simulation the remittances are increased by 50 percent. Equivalent variations (EVs) and Foster-Greer-Thorbecke (FGT) measures are applied to estimate welfare and poverty changes respectively. The prime observation is that rural poverty, as measured by the head count ratio, is observed to increase under all three simulations. The gap and severity of the rural poor have also worsened in all three simulations indicating worse poverty profiles for the rural poor compared to the base-run scenario. Urban head count poverty has also deteriorated in the first and second simulations, while has improved only in the third simulation. The gap and severity of poverty for the urban population have, however, deteriorated in all three simulations.

description: An open quantum system refers to a system that is further coupled to a bath system consisting of surrounding radiation fields, atoms, molecules, or proteins. The bath system is typically modeled by an infinite number of harmonic oscillators. This system-bath model can describe the time-irreversible dynamics through which the system evolves toward a thermal equilibrium state at finite temperature. In nuclear magnetic resonance and atomic spectroscopy, dynamics can be studied easily by using simple quantum master equations under the assumption that the system-bath interaction is weak (perturbative approximation) and the bath fluctuations are very fast (Markovian approximation). However, such approximations cannot be applied in chemical physics and biochemical physics problems, where environmental materials are complex and strongly coupled with environments. The hierarchical equations of motion (HEOM) can describe numerically "exact" dynamics of a reduced system under nonperturbative and non-Markovian system--bath interactions, which has been verified on the basis of exact analytical solutions (non-Markovian tests) with any desired numerical accuracy. The HEOM theory has been used to treat systems of practical interest, in particular to account for various linear and nonlinear spectra in molecular and solid state materials, to evaluate charge and exciton transfer rates in biological systems, to simulate resonant tunneling and quantum ratchet processes in nanodevices, and to explore quantum entanglement states in quantum information theories. This article, presents an overview of the HEOM theory, focusing on its theoretical background and applications, to help further the development of the study of open quantum dynamics.

Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to examine the effectiveness of Instrumental Enrichment, an educational program developed by Reuven Feuerstein, which attempts to improve an individual's ability to reason. A meta-analysis was performed on studies that had been conducted between the years 1979 to 1996. Thirty-six studies were analyzed according to their results from measurements in the cognitive/visual-perceptual, academic achievement and affective domains. The results from the meta-analysis were mixed. There were significant combined effect sizes of 0.24 for non-verbal ability, 1.41 for verbal ability, and 0.60 for one combination of full-scale ability. Significant effect sizes for measures of visual perception and visual-motor ability were 0.42, 0.71 and 1.68. There were also significant effect sizes for general achievement and for one combination of math achievement at 0.26 and 0.29 respectively. The intellectual achievement locus of control effect size was significant at 0.33. (Cohen (1988) considers an effect size of 0.20 to be small, that of 0.50 to be of medium size, and that of 0.80 to be large.) All effect sizes for reading were non-significant as was that for the Learning Potential Assessment Device. All other measures, such as those for self-confidence, self-concept, motivation and attitudes, in the affective domain were non-significant. One effect size for motivation and attitudes was significantly negative, indicating that the control group outperformed the treatment group. The results are discussed in terms of near- and far-transfer of learning.

description: Numerical models are starting to be used for determining the future behaviour of seismic faults and fault networks. Their final goal would be to forecast future large earthquakes. In order to use them for this task, it is necessary to synchronize each model with the current status of the actual fault or fault network it simulates (just as, for example, meteorologists synchronize their models with the atmosphere by incorporating current atmospheric data in them). However, lithospheric dynamics is largely unobservable: important parameters cannot (or can rarely) be measured in Nature. Earthquakes, though, provide indirect but measurable clues of the stress and strain status in the lithosphere, which should be helpful for the synchronization of the models. The rupture area is one of the measurable parameters of earthquakes. Here we explore how it can be used to at least synchronize fault models between themselves and forecast synthetic earthquakes. Our purpose here is to forecast synthetic earthquakes in a simple but stochastic (random) fault model. By imposing the rupture area of the synthetic earthquakes of this model on other models, the latter become partially synchronized with the first one. We use these partially synchronized models to successfully forecast most of the largest earthquakes generated by the first model. This forecasting strategy outperforms others that only take into account the earthquake series. Our results suggest that probably a good way to synchronize more detailed models with real faults is to force them to reproduce the sequence of previous earthquake ruptures on the faults. This hypothesis could be tested in the future with more detailed models and actual seismic data.

description: Nb$_3$Sn is a promising advanced material under development for superconducting radiofrequency (SRF) cavities. Past efforts have been focused primarily on small development-scale cavities, but large, often multi-celled cavities, are needed for particle accelerator applications. In this work, we report on successful Nb$_3$Sn coatings on Nb in a 1 m-long 9-cell Nb sample-host cavity at Fermilab. The geometry of the first coating with only one Sn source made it possible to study the influence of Sn flux on the microstructure. Based on these results, we postulate a connection between recently observed anomalously large thin grains and uncovered niobium spots observed in the past by other authors [Trenikhina 2018]. A phenomenological model to explain how these anomalously large grains could form is proposed. This model is invoked to provide possible explanations for literature results from several groups and to guide key process parameters to achieve uniform vapor-diffusion coatings, when applied to complex structures as the multi-cell cavity under study.

By adopting the visibility graph algorithm, the four economic policy uncertainty indices of the United States and China are mapped into complex networks, and the topological properties of the corresponding networks are studied. The Hurst exponents of all the four indices are within $\left[0.5,1\right]$, which implies that the economic policy uncertainty is persistent. The degree distributions of the EPU networks have power-law tails and are thus scale-free. The average clustering coefficients of the four EPU networks are high and close to each other, while these networks exhibit weak assortative mixing. We also find that the EPU network in United States based on daily data shows the small-world feature since the average shortest path length increases logarithmically with the network size such that $L\left(N\right)=0.626\ln N+0.405$. Our research highlights the possibility to study the EPU from the view angle of complex networks.

description: Motivated by models proposed to explain the Standard Model anomalies, and the unprecedented $τ^{+}τ^{-}$ data to be collected by the Belle~II experiment during the next years, we study the kinematics of tau pair decays and propose a new method to search for lepton flavor violating processes in tau lepton decays to invisible beyond Standard Model particles, such as $τ\to \ell α$, where $\ell$ is either an electron or a muon, and $α$ is a massive particle that escapes undetected. The new method improves by one order of magnitude the expected upper limit on the $τ\to \ell α$ production in 3x1 prong tau decays and establishes the possibility of performing this search in 1x1 prong tau decays which has not been previously considered.

description: A binary system composed of an oscillating and rotating coplanar dusty disk and a point mass is considered. The conservative dynamics is treated on the Newtonian level. The effects of gravitational radiation reaction and wave emission are studied to leading quadrupole order. The related waveforms are given. The dynamical evolution of the system is determined semi-analytically exploiting the Hamiltonian equations of motion which comprise the effects both of the Newtonian tidal interaction and the radiation reaction on the motion of the binary system in elliptic orbits. Tidal resonance effects between orbital and oscillatory motions are considered in the presence of radiation damping.

From World to Word and Back: An Empirical and Philosophical Investigation on Syntactical Bootstrapping

description: This thesis has two connected components: an empirical project and a philosophical project
In the empirical project I present an experiment investigating syntactic bootstrapping as a noun learning mechanism. Previous studies have shown that infants as young as 6.5 months of age can perceive the causal relationship in a simple Michotte launching event. Yet it is not until the age of 2 year that children show evidence of reasoning with causality (Gopnik & Sobel, 2000; Gopnik, Sobel, Shulz & Glymour, 2001; Nazzi & Gopnik, 2003; Sobel, Tenenbaum & Gopnik, 2004). One reason for this lag is language. A conceptual understanding of causality requires understanding causal language, and the developmental trajectory of causal language in early childhood remains unclear. Studies have shown that toddlers at 15 months of age can match the transitive structure of the sentence to a causative event through a mechanism known as syntactic bootstrapping (Jin & Fisher, 2014). In the current experiments, we tested whether 12-month-olds and 20-month-olds can rely on the same mechanism to acquire the association between the subject of the sentence and the causal agent of the event. Due to COVID-19 outbreak, the data collection process was interrupted. Only preliminary data was presented in this paper, with discussion focused on the implications of different potential outcomes.
In the philosophical project I present a theoretical review on the foundations of infant looking time paradigms. In the past decades, the looking time measurement has been the backbone of developmental psychology. Most of our understanding of infant perceptual and cognitive development came from research using at least one of the three looking time paradigms: habituation, familiarization, and Violation of Expectation. However, the myriad claims supported by infant looking time paradigms suffer from what Richard Aslin called a “many-to-one” problem: there are many different postulated hypotheses, but only one measurement available (Aslin, 2007). The vast underdetermination between the evidence and the interpretation originates from the lack of attention devoted to the theoretical foundations of the looking time paradigms. In this paper, I surveyed and compared the four most prevalent theories in the field: The Comparator Theory, the Multifactor Model, the Object File Theory, and the Dual Process Theory. I analyzed each theory’s strengths and weaknesses in the context of experimental design and data interpretation. I also compared the four theories against each other to assess their explanatory scope. I arrived at the conclusion that none of the theories currently available is sufficient to justify the connection between the evidence and the interpretation. In the future, more systematic investigations are needed to construct a more precise, quantitative interpretation framework to guide empirical research.

description: We investigate stability of both localized time-periodic coherent states (pulsons) and uniformly distributed coherent states (oscillating condensate) of a real scalar field satisfying the Klein-Gordon equation with a logarithmic nonlinearity. The linear analysis of time-dependent parts of perturbations leads to the Hill equation with a singular coefficient. To evaluate the characteristic exponent we extend the Lindemann-Stieltjes method, usually applied to the Mathieu and Lame equations, to the case that the periodic coefficient in the general Hill equation is an unbounded function of time. As a result, we derive the formula for the characteristic exponent and calculate the stability-instability chart. Then we analyze the spatial structure of the perturbations. Using these results we show that the pulsons of any amplitudes, remaining well-localized objects, lose their coherence with time. This means that, strictly speaking, all pulsons of the model considered are unstable. Nevertheless, for the nodeless pulsons the rate of the coherence breaking in narrow ranges of amplitudes is found to be very small, so that such pulsons can be long-lived. Further, we use the obtaned stability-instability chart to examine the Affleck-Dine type condensate. We conclude the oscillating condensate can decay into an ensemble of the nodeless pulsons.

description: Excerpts from the report Summary: The purpose of this report is to outline to cotton warehousemen a few suggestions as to how more efficient methods for handling cotton may be devised or discovered, and to list and briefly discuss some broad principles of materials handling, which, when applied to the warehousing of cotton, should result in increasing handling efficiency and in reducing handling costs. Most inefficiencies in the handling of cotton result from one or more of the following reasons: (1) Failure to use suitable powered handling equipment in place of manual labor; (2) failure to make proper and effective use of such equipment when it is employed; and (3) failure to make effective use of the manual labor employed. To eliminate or reduce such inefficiencies it is necessary to examine handling operations with a view toward finding out how the inefficiencies came about, in order to remove the sources of trouble.
