What hinders and helps individuals accessing healthcare services for Fibromyalgia : a critical incident study
Creators: name: Nishikawara, Ria
Publisher: name: University of British Columbia
Year: 2017

description: Fibromyalgia (FM) is a complex condition characterized by chronic diffuse pain and increased sensitivity to pain, chronic fatigue and sleep disturbance, cognitive difficulties, as well as a range of co-occurring conditions. While FM presents with severe and often debilitating symptoms, it has no known aetiology, and cannot be identified by any objective tests; as a result, it poses diagnostic and treatment problems within the conventional biomedical healthcare system, often leaving patients struggling to find adequate care. While a growing body of literature has explored the topic of FM, it is largely focused on either biomedical perspectives, or ways the condition impacts individuals’ lives. To date, little research has explored healthcare experiences for individuals with FM. The present study used the enhanced critical incident technique (ECIT) to explore the hindering and helping experiences of healthcare of 14 individuals diagnosed with FM, as well as what these individuals believe would have been helpful had they been available. Results identified 16 categories, further organized across the five environmental systems of the ecological systems theory (EST). The EST can be visualized as five concentric circles, representing systems or spheres of influence, with the individual, or person, at the centre. The outermost layer, the macrosystem, which encompasses the cultural environment in which a person lives, contained two categories: clinical understanding of FM, and prejudice. The second layer, the exosystem, which encompasses the larger social system, contained four categories: financial and economic security and affordability of services, models of healthcare delivery, accessibility and flexibility, and diagnosis making. The third layer, the mesosystem, which encompasses interactions between parts of a person’s microsystems, contained one category: continuity of care. The fourth layer, the microsystem, which the person’s direct relationships, contained five categories: therapeutic alliance, informed consent, iatrogenic suffering, validation, and counselling and psychotherapy. The innermost layer, the person, which encompasses a person’s personal characteristics, contained four categories: internalization of adverse healthcare experiences, medication, exercise and physical activity, and active coping and social support. These results can serve to inform counsellors and other healthcare providers who work with patients with FM, as well as future research.
Enabling Technologies for Visible Adaptive Optics: The Magellan Adaptive Secondary VisAO Camera

description: Since its beginnings, diffraction-limited ground-based adaptive optics (AO) imaging has been limited to wavelengths in the near IR (λ > 1 micron) and longer. Visible AO (λ < 1 micron) has proven to be difficult because shorter wavelengths require wavefront correction on very short spatial and temporal scales. The pupil must be sampled very finely, which requires dense actuator spacing and fine wavefront sampling with large dynamic range. In addition, atmospheric dispersion is much more significant in the visible than in the near-IR. Imaging over a broad visible band requires a very good Atmospheric Dispersion Corrector (ADC). Even with these technologies, our AO simulations using the CAOS code, combined with the optical and site parameters for the 6.5m Magellan telescope, demonstrate a large temporal variability of visible (λ=0.7 micron) Strehl on timescales of 50 ms. Over several hundred milliseconds, the visible Strehl can be as high at 50% and as low as 10%. Taking advantage of periods of high Strehl requires either the ability to read out the CCD very fast, thereby introducing significant amounts of read-noise, or the use of a fast asynchronous shutter that can block the low-Strehl light. Our Magellan VisAO camera will use an advanced ADC, a high-speed shutter, and our 585 actuator adaptive secondary to achieve broadband (0.5-1.0 micron) diffraction limited images on the 6.5m Magellan Clay telescope in Chile at Las Campanas Observatory. These will be the sharpest and deepest visible direct images taken to date with a resolution of 17 mas, a factor of 2.7 better than the diffraction limit of the Hubble Space Telescope.

description: In order to find the selection rules that can be applied to the electromagnetic transitions when the chiral geometry is achieved, a model for a special configuration in triaxial odd-odd nuclei is constructed which exhibits degenerate chiral bands with a sizable rotation. A quantum number obtained from the invariance of the Hamiltonian is given and the selection rule for electromagnetic transition probabilities in chiral bands is derived in terms of this quantum number. Among the available candidates for chiral bands of odd-odd nuclei, in which the near degeneracy of two $ΔI = 1$ bands is observed, the measured electromagnetic properties of the two bands in $^{128}_{55}$Cs$_{73}$ and $^{126}_{55}$Cs$_{71}$ are consistent with the rules, while those of $^{134}_{59}$Pr$_{75}$ and $^{132}_{57}$La$_{75}$ are not.

description: The injection of ultra-high energy cosmic rays in the intergalactic medium leads to the production of a GeV-TeV gamma-ray halo centered on the source location, through the production of a high electromagnetic component in the interactions of the primary particles with the radiation backgrounds. This paper examines the prospects for the detectability of such gamma ray halos. We explore a broad range of astrophysical parameters, including the inhomogeneous distribution of magnetic fields in the large scale structure as well as various possible chemical compositions and injection spectra; and we consider the case of a source located outside clusters of galaxies. With respect to the gamma-ray flux associated to synchrotron radiation of ultra-high energy secondary pairs, we demonstrate that it does not depend strongly on these parameters and conclude that its magnitude ultimately depends on the energy injected in the primary cosmic rays. Bounding the cosmic ray luminosity with the contribution to the measured cosmic ray spectrum, we then find that the gamma-ray halo produced by equal luminosity sources is well below current or planned instrument sensitivities. Only rare and powerful steady sources, located at distances larger than several hundreds of Mpc and contributing to a fraction > 10% of the flux at 10^19 eV might be detectable. We also discuss the gamma-ray halos that are produced by inverse Compton/pair production cascades seeded by ultra-high energy cosmic rays. This latter signal strongly depends on the configuration of the extragalactic magnetic fields; it is dominated by the synchrotron signal on a degree scale if the filling factor of magnetic fields with B > 10^(-14) G is smaller than a few percents. Finally, we discuss briefly the case of nearby potential sources such as Centaurus A.

description: Rhodium(I) carbonyl complexes of the form [RhI(N,O-ScBa)(CO)(PR3)] (R = Ph or Cy), with N,O-ScBaH a mono anionic bidentate Schiff base ligand, 2-(cyclopentyliminomethyl)-5-methylphenol (5-Me-Sal-CyPH), and bearing different phosphine ligands on Rh(I), are reported. N,O-ScBaH was also varied to be 2-(cyclohexyliminomethyl)phenol (Sal-CyH) and 2-(isopropyliminomethyl)-5-methylphenol (5-Me-Sal-IPropH) to investigate the effects of different substituent groups on the periphery of the Schiff bases on metal center reactivity. The structural characterization of two sample complexes is described and an extensive spectroscopic kinetic-mechanistic study utilizing UV/vis, infrared and 31P NMR spectroscopy of the iodomethane oxidative addition is presented. Iodomethane oxidative addition led exclusively to RhIII-alkyl complexes as final products, while an associative activation is inferred from the large negative ΔS ≠ value. The relative reactivity of the [RhI(N,O-ScBa)(CO)(PR3)] complexes when stepwise varying PR3 (PPh3, PPh2Cy, PPhCy2 and PCy3) as tertiary phosphine ligands follow a surprising similar reactivity relationship as observed for a range of isostructural [RhI(X,O-Bid)(CO)(PR3)] complexes, with X = O, N or S in corresponding oxinate, acetylacetonate and thioureate mono anionic X,O-Bid ligands. This suggests systematic and responsive dynamic behavior of the PR3 ligands, independent of the bidentate chelate at the Rh(I) metal center. A variation of more than two orders-of-magnitude in reactivity was observed.

description: The Hellenic Association of Agricultural Economists (ETAGRO), having completed 30 years of continuous scientific presence, organized the 15th Panhellenic Conference (in November 2018), which has an anniversary character, entitled “Redefining Rural Development in the Modern Digital Era”. The main aim of this conference was to bridge communication and cooperation between the agricultural economics scientists, the institutions, but also those involved with the rural area, contributing to the exchange of research results and know-how. The interest in the improvement of agricultural production and wider rural areas is always a common goal for those involved in the rural economy and policy. In this context, the conference was an important step, in which the new data formed by the digital era for the development of all sectors of the rural area were presented. The conference was held at a time when on the one hand, the economic crisis continues and on the other hand, the Common Agricultural Policy of the period 2015-2020 has reached the middle of its life, and the processes for planning the next programming period have already begun. At the same time, Greek agriculture needs to address important environmental issues, such as the inefficient use of irrigation water, as well as the potential effects of climate change, which undermine the sustainability of the industry. The use of technology (precision agriculture) can significantly contribute to addressing the above problems, but the effective implementation of which, in several cases, has the need to change the existing structures of Greek agriculture. Technology developments focusing on improving access to data and information, facilitating communication, raising environmental awareness and developing transport lead to new - and often drastic - changes in the way agriculture is practiced internationally and, in the country, while influencing rural development policies. On the other hand, the socio-economic and financial framework that is being formed as a result of the severe recession, which has hit and continues to hit the country's economy hard, makes it difficult to integrate all these developments. However, this difficult situation is a real motivation of the domestic agricultural sector, for the identification and long-term utilization of international markets, for the integration and efficient utilization of modern supply systems, the modernization and reorganization of the production process, in order to create value-added chains of agricultural or food products.

description: Software architecture assists developers in addressing non-functional requirements and in maintaining, debugging, and upgrading their software systems. Consequently, consistency between the designed architecture and the implemented software system itself is important; without this consistency the non-functional requirements targeted may not be addressed and architectural documentation may mis-direct maintenance efforts that target the associated code-base. But often, when software is initially implemented or subsequently evolved, the designed architecture and software architecture become inconsistent, with the implemented structure degraded due to issues like developer time-pressures, or ambiguous communication of the designed architecture. In such cases, Software Architecture Recovery (SAR) or consistency approaches can be applied to reconstruct the architecture of the software system and possibly to compare it to/re-align it with the designed architecture. Many SAR approaches have been proposed in the research. However, choosing an appropriate architecture recovery approach for software systems is still an open issue. Consequently, this research aims to conduct a tertiary-mapping study based on available secondary studies of architecture recovery approaches, to uncover important characteristics, towards the selection of appropriate SAR approaches. This research has aggregated 13 secondary studies and 10 primary studies beyond 2020 from 5 databases and, in doing so, identified 111 architecture recovery approaches. Based on these approaches, a taxonomy, containing nine main SAR-selection categories is proposed and a framework (in the form of a supporting tool to help developers select an appropriate SAR approach) has been developed. Finally, this research identifies six potential open research gaps related to the underlying research that could be helpful for guiding research in the future.

description: We study a uniform matrix product state as a variational state for classical and quantum spin chains in the thermodynamic limit. Under a careful treatment of the translational symmetry, eigen values of the transfer matrix defined in the calculation of expectation values can reflect the periodicity of the ground state and indicate optimum periodicity of the matrix product state. We discuss the relation between the periodicity and accuracy of magnetization curves. This approach is free from the error due to finite system size, which works well especially for the magnetic plateau problem.

description: The bis-sulfonamide TAML activator of peroxides [Fe{4-NO2C6H3-1,2-(NCOCMe2 NSO2)2CHMe}]- (2) catalyzes the H2O2 oxidation of microcystin-LR (m-LR), a common surface water contaminant produced by cyanobacteria that is toxic at very low concentrations. The major reaction product is by 16 Da heavier than m-LR, suggesting that the first oxidative step involves addition of oxygen to one of m-LRs three C = C units to form an epoxide. The kinetic data suggest that the m-LR → m + 16 conversion occurs without any kinetically meaningful intermediate with the catalytic rate constant k II of 2.5 × 105 M−1 s−1, which characterizes the interaction of m-LR with the oxidized, active form of the catalyst. The primary m + 16 product undergoes much slower further catalytic oxidation in the aqueous reaction medium. This communication describes a potential utility of TAML/H2O2 catalysis for microcystin detoxification that calls for further research.

description: A promising practical application of entanglement is metrology, where quantum states can be used to make measurements beyond the shot noise limit. Here we consider how metrology schemes could be realised using atomic Bose-Einstein condensates (BECs) trapped in different potentials. In particular, we show that if a trapped BEC is rotated at just the right frequency, it can undergo a quantum phase transition characterised by large-scale entanglement spreading across the system. This simple process of stirring can generate interesting quantum states such as macroscopic superpositions of all the atoms flowing in opposite directions around a ring-shaped potential. We consider different trapping potentials and show how this leads to different entangled states. In particular, we find that by reducing the dimensionality of the system to one or two dimensions, it is possible to generate entangled states that are remarkably robust to the loss of atoms and so are ideally suited to precision measurement schemes.

description: Two metallacyclophanes have been assembled by self-assembly processes involving the trianionic compartmental ligand (L3-), nickel(II) and sodium or potassium ions: [LNiNa]2·C2H5OH·2H2O (1) and [LNiK]2·C2H5OH·2H2O (2) (the Schiff-base proligand, H3L, is obtained by condensation of o-vanillin and DL-2,3-diaminopropionic acid). The structures of 1 and 2 can be viewed as resulting from two enantiomeric fragments, {LNiNa/K} connected to each other by the two carboxylato groups. The intramolecular distance between the phenyl rings is 3.64 Å. The sodium/potassium ions are coordinated by five oxygens in a planar pentagon. Weak intermolecular sodium/potassium···CH interactions are observed in the packing diagrams of the two compounds. The intra- and intermolecular non-covalent interactions are analyzed through several methods based on electron density, Bader’s QTAIM, non-covalent interactions index and natural bond orbitals. They confirm the in-plane five coordination of the alkali ion, which is of an electrostatic, non-covalent nature and the intermolecular interaction with σ C-H orbitals as well. The diffuse reflectance spectra of the two compounds show characteristic features of square-planar nickel(II) chromophores.

description: The nanobeam resonator is the key mechanical component in the nano-electromechanical system. In addition to its high frequency originating from its low dimension, the performance is significantly influenced by the circumstances, especially at nanoscale where a large surface area of the material is exposed. Molecular dynamics simulations and theoretical analysis are used for a quantitative prediction on the damping behavior, such as the critical damping condition and lifetime, of nanobeam resonators that directly maps the fluid-structure properties and interaction information into dynamical behaviors. We show here how the humidity defines the critical damping condition through viscous forces, marking the transition from under-damping to over-damping regime at elevated humidity. Novel phenomena such as the thermal fluctuation and paddling effects are also discussed.

description: A low-valent [FeN5(OTf)2] complex and its bisnitrite adduct, [FeN5(NO2)2], have been synthesized in the interest of extending the reactivity of Fe complexes featuring redox-active ligands with secondary coordination sphere hydrogen-bond donors to nitrite reduction. Crystallographic characterization of [FeN5(NO2)2] reveals that the nitrite ligands demonstrate both ɳ 1-NO2 (N-nitro) and ɳ 1-ONO (O-nitrito) coordination modes. H-bonding between nitrite ligands and the protons on secondary amine moieties in the N5  ligand play a pivotal role in positioning the nitrite ligands in multiple coordination modes. These results provide insights into the role of H-bonding in supporting disparate coordination modes of this substrate that can be translated to mechanisms of nitrite reduction in biological systems.

On the impact of negatively keyed items on the assessment of the unidimensionality of psychological tests and measures
Creators: name: Chen, Yue
Publisher: name: University of British Columbia
Year: 2017

description: Evidence of test dimensionality supports test scoring, and it is essential to construct validity. Yet many issues remain unclear in assessing dimensionality, especially when the response data are collected through self-report Likert-type tests that include negatively keyed items. The emergence of additional factors that can be attributed to the mixed-keyed format is an issue that draws much attention in investigating the dimensionality of tests that are designed to be unidimensional. Common methods for assessing dimensionality can be categorized into two types: exploratory and confirmatory. Exploratory studies use many rules and criteria, such as the eigenvalues-greater-than-one (K-G) rule and parallel analysis (PA), along with exploratory factor analysis (EFA) to help researchers determine the number of factors (i.e., dimensions). Confirmatory factor analysis (CFA), on the other hand, is often employed to examine the fit of a hypothesized measurement model. A large number of fit indices, including the Chi-square test, the comparative fit index (CFI), and the root mean square error of approximation (RMSEA), have been proposed to evaluate a model’s overall fit. This dissertation investigated, via computer simulation, how these various procedures performed in assessing the dimensionality of item response data collected using tests with negatively keyed items. Factors in the simulation experiment included psychometric models (i.e., the simulation methods) of negatively keyed items, the number of negatively keyed items, the magnitude of item communality, the distribution of observed item response, the scoring methods of negatively keyed items, and the methods and rules used for the statistical judgment of dimensionality. This dissertation adopts the threshold model of item responses, which assumes a monotonic relationship among the latent variable, item thresholds, and observed item responses. The results indicate that the dimensionality of tests with mixed-keyed items is always correctly identified when the observed item response distribution is symmetric. When it is asymmetric, however, the methods and decision rules used in dimensionality assessment affect the statistical judgment of test dimensionality. The results highlight the benefit of using categorical data analytic methods in dealing with item responses obtained through Likert-type rating scales. Guidelines are provided to inform researchers when assessing the dimensionality of mixed-keyed tests.

description: Semantic Web is an open, distributed, and dynamic environment where access to resources cannot be controlled in a safe manner unless the access decision takes into account during discovery of web services. Security becomes the crucial factor for the adoption of the semantic based web services. An access control means that the users must fulfill certain conditions in order to gain access over web services. Access control is important in both perspectives i.e. legal and security point of view. This paper discusses important requirements for effective access control in semantic web services which have been extracted from the literature surveyed. I have also discussed open research issues in this context, focusing on access control policies and models in this paper.

description: A new 3 D polyoxometalate, H7K3[Na2Cu3(H2O)(B-α-SbW9O33)2]·8H2O (1), has been hydrothermally made and characterized by IR spectroscopy, thermogravimetric analyses, powder X-ray diffraction and single crystal X-ray diffraction analysis. 1 crystallizes in the tetragonal system, space group P-421 m, with a = 16.7532(7) Å, b = 16.7532(7) Å, c = 13.8335(11) Å and Z = 2. Structure analysis reveals that the polyanion in 1 consists of two B-α-SbW9O33 ({SbW9}) units sandwiched by a U-shaped {Na2Cu3} cluster made by two Na+ and three Cu2+ ions. The most prominent structural feature of 1 is that the [Na2Cu3(H2O)(B-α-SbW9O33)2]10– ({Na2Cu3(SbW9)2}) units are connected to construct a 2 D network through Cu–O = W bridges. To the best of our knowledge, 1 represents the first sample with an unclosed central belt between two {SbW9} fragments. Furthermore, neighboring 2 D networks connect by K+ cations to form a 3 D framework. The semiconductor behavior, electrochemical properties and photocatalytic activities have been investigated, showing excellent photocatalytic and electrocatalytic activities for the photodegradation of MB/RhB and bromate reduction.

description: Let $X$ be a Banach space. We prove that, for a large class of Banach or quasi-Banach spaces $E$ of $X$-valued sequences, the sets $E-\bigcup _{q\inΓ}\ell_{q}(X)$, where $Γ$ is any subset of $(0,\infty]$, and $E-c_{0}(X)$ contain closed infinite-dimensional subspaces of $E$ (if non-empty, of course). This result is applied in several particular cases and it is also shown that the same technique can be used to improve a result on the existence of spaces formed by norm-attaining linear operators.

description: We investigate the viability of Affleck-Dine baryogenesis in D=4, N=1 supergravity descending from string theory. The process relies on an initial condition where visible sector supersymmetric flat directions obtain tachyonic masses during inflation. We discuss this condition for a variety of cases where supersymmetry is broken during inflation by a geometric modulus or hidden sector scalar, and outline scenarios where the initial condition is satisfied.

description: Consumers perceptions hold a vital role in any development concerning the food supply chains especially, new generational consumer cohorts like iGeneration and Millennials that will shape tomorrow’s food supply chains. This study focuses on these consumer segments and aims in investigating what features influence their perceived value towards a traceability system in food supply chains. Results showed that concerns about health, food safety and trust are key elements which affect consumers perceived value on traceable foods with some differences between the studied cohorts. Several implications in the agri-food sector are discussed, from both a supply chain management and policy-making perspective.

description: The main aim of this paper is narrowing the innovation divide on entrepreneurship and the effective application of sustainable Precision Agriculture (PA). For this purpose, the Business Model Canvas (BMC) analysis was carried out for farms belonging to different crop sectors in Greece. The goal is to present how the use of BMC methodology analyses the entrepreneurial formula of farms that have successfully implemented PA technologies. Furthermore, it can be a new tool towards “Agriculture 4.0” to support companies that could invest in PA in order to grow economically and, at the same time, decrease the environmental impact. To succeed this, 5 BMC analyses were performed and SWOT analysis to investigate barriers, drivers, benefits, and impact, according to the entrepreneur’s perception, towards the implementation of PA technologies. Finally, there was evaluation research of the BMC experience from both the interviewed farmers’ and interviewers’ point of view. The results of this analysis showed that the samples of the five cases have a common attitude regarding PA. On the one hand, the barriers highlighted where the lack of knowledge, lack of support systems and high investment costs. On the other hand, the benefits where higher quality productivity and profitability and lower environmental and control costs. As for the drivers and the expected impact, all farmers agreed on the development of a more environmentally friendly sustainable agriculture with reduced costs. Finally, this paper clarifies how the “human factor” is the element key to motivate farmers to adopt PA practices.

description: The characterization of polyoxometalates (POMs) structures in solutions is challenging although X-ray diffraction is widely used to solve the POMs’ crystalline structures. Here, we introduce small-angle X-ray scattering (SAXS) to explore the solutions of several emergent POMs mainly from Prof. Enbo Wang’s group. Direct evidence of their crystal structure retained in solution is obtained by fitting their SAXS data with appropriate crystal structure models, ensuring credibility of their applications for catalysis and magnetism. The capability of distinguishing dimer and monomer structures of {Ce20W100} in solution is of special interest, which is difficult for other characterization techniques.

description: We present results on coherent control of ultracold trap-loss collisions using 40 ns pulses of nonlinearly frequency-chirped light. The chirps, either positive or negative, sweep ~1 GHz in 100 ns and are centered at various detunings below the D2 line of 85Rb. At each center detuning, we compare the collisional rate constant beta for chirps that are linear in time, concave-down and concave-up. For positive chirps, we find that beta generally depends very little on the shape of the chirp. For negative chirps, however, we find that beta can be enhanced by up to 50(20)% for the case of the concave-down shape. This occurs at detunings where the evolution of the wavepacket is expected to be coherent. An enhancement at these detunings is also seen in quantum mechanical simulations of the collisional process.

description: We present a combinatorial approach for development of materials for use in optical gas sensors, with oxygen being used as an exemplary target gas. Combinatorial chemistry is shown to be a promising tool for speeding up the search for new sensor materials. The method is based on the use of various polymers, solvents, indicators, plasticizers, and other additives. Solutions of the respective materials are prepared in appropriate organic solvents, and a robotic station is programmed to mix the components. Spots of the sensing materials are deposited in the wells of glass substrates resembling microtiterplates. After drying off the solvent, the sensor spots are automatically analyzed in a test stand, where they are exposed to a carrier gas containing oxygen in various concentrations. Changes in the decay time of fluorescence of the indicator probes are measured and used (along with sensor response time) as a main criterion for sensor assessment. It is shown that the combinatorial approach can reduce the time and effort needed to establish libraries of sensor materials by a factor of at least 1000. We describe in detail the device for preparation of sensor libraries and for testing the respective materials. The potential of the system is demonstrated for the characterization of optical oxygen sensors.
