Archival law from the trenches : the impact of archival legislation on records management in commonwealth countries
Creators: name: Goh, Elaine Mei Yee
Publisher: name: University of British Columbia
Year: 2016

description: Archival legislation in several Commonwealth countries provides the national archives with the statutory mandate to manage and preserve government records. The archival literature recognizes that archival legislation lags behind advances in technology and that it is often not robust enough to support the management and preservation of records. However, there is a lack of empirical research on how archival legislation is operationalized within specific socio-political, cultural, and juridical contexts, and on the perceptions of archivists and records managers about such operationalization. This dissertation addresses how the operationalization of archival legislation in the UK, Canada, and Singapore influences its effectiveness in the implementation of records management programs. The study takes into account the common law system based on an intergovernmental organization, the Commonwealth, as well as the different socio-political and cultural contexts of the countries. To explore the shared and varying views that archivists and records managers have on archival legislation, the study largely employs interpretivist perspectives and hermeneutic principles to examine interviews conducted with archivists and records managers, selected legislation, normative sources, and other documentary sources related to the enactment of archival legislation. The findings of this research suggest that archival legislation operates in the context of a patchwork constituted by other records-related legislation and normative sources, and that there are complexities involved in making amendments to such legislation. There are also organizational culture issues that stem from the institutional relationships between the national archives and government departments and the individual-level relationships of archivists and records managers. These issues can enable and constrain the delivery of a records management program. Additionally, the joint responsibilities in recordkeeping and record preservation held by the national archives and other departments that have an interest in information management result in a collaboration constraint and have contributed to a perceived lack of leadership on the part of the national archives in records management. The study concludes with recommendations for the decoupling of archival national institutions from national archival legislation, and for a comprehensive regulation of all aspects of records creation, maintenance, and preservation in the public sector.

description: Distributed embedded systems (DESs) are no longer the exception; they are the rule in many application areas such as avionics, the automotive industry, traffic systems, sensor networks, and medical devices. Formal DES specification and verification is challenging due to state space explosion and the need to support real-time features. This paper reports on an extensive industry-based case study involving a DES product family for a pedestrian and car 4-way traffic intersection in which autonomous devices communicate by asynchronous message passing without a centralized controller. All the safety requirements and a liveness requirement informally specified in the requirements document have been formally verified using Real-Time Maude and its model checking features.

description: We report on measurements of the superconducting properties of FeSe05Te05 thin films grown on lanthanum aluminate. The films have high transition temperatures (above 19 K) and sharp resistive transitions in fields up to 15 T. The temperature dependence of the upper critical field and the irreversibility lines are steep and anisotropic, as recently reported for single crystals. The critical current densities, assessed by magnetization measurements in a vector VSM, were found to be well above 10^9 Am-2 at low temperatures. In all samples, the critical current as a function of field orientation has a maximum, when the field is oriented parallel to the film surface. The maximum indicates the presence of correlated pinning centers. A minimum occurs in three films, when the field is applied perpendicular to the film plane. In the forth film, instead, a local maximum caused by c-axis correlated pinning centers was found at this orientation. The irradiation of two films with fast neutrons did not change the properties drastically, where a maximum enhancement of the critical current by a factor of two was found.

description: Unlike c-plane nitrides, ``non-polar" nitrides grown in e.g. the a-plane or m-plane orientation encounter anisotropic in-plane strain due to the anisotropy in the lattice and thermal mismatch with the substrate or buffer layer. Such anisotropic strain results in a distortion of the wurtzite unit cell and creates difficulty in accurate determination of lattice parameters and solid phase group-III content (x_solid) in ternary alloys. In this paper we show that the lattice distortion is orthorhombic, and outline a relatively simple procedure for measurement of lattice parameters of non-polar group III-nitrides epilayers from high resolution x-ray diffraction measurements. We derive an approximate expression for x_solid taking into account the anisotropic strain. We illustrate this using data for a-plane AlGaN, where we measure the lattice parameters and estimate the solid phase Al content, and also show that this method is applicable for m-plane structures as well.

description: Purpose: There is emerging recognition within the literature that speech-language pathologists (SLPs) have a role in the provision of paediatric palliative care (PPC). SLPs, however, experience unique challenges when working with this vulnerable young cohort of patients, their families and multidisciplinary teams. This study aims to develop practice recommendations based on best available evidence. Method: A modified Delphi technique was utilised to develop group consensus over a series of survey rounds. Statements for voting were synthesised by critically reviewing recurring themes from previous studies, involving (i) a scoping literature review, (ii) an online survey, and (iii) interview data. Nine participants were recruited using consecutive sampling from the interview phase related to this study. Result: Twenty-one statements were voted upon over two survey rounds (100% response rate). Agreement levels of ≥70% across all statements were reached after the first round. There was a significant correlation between rating a statement as “essential” and a strong level of agreement (p Conclusion: The 21 statements form Recommendations for Speech-Language Pathologists in Paediatric Palliative Care Teams (ReSP3CT). The statements will support SLPs working within PPC to promote advocacy, professional development and enhance team involvement in this developing field.

description: Safety of medical devices and of their interoperation is an unresolved issue causing severe and sometimes deadly accidents for patients with shocking frequency. Formal methods, particularly in support of highly reusable and provably safe patterns which can be instantiated to many device instances can help in this regard. However, this still leaves open the issue of how to pass from their formal specifications in logical time to executable emulations that can interoperate in physical time with other devices and with simulations of patient and/or doctor behaviors. This work presents a specification-based methodology in which virtual emulation environments can be easily developed from formal specifications in Real-Time Maude, and can support interactions with other real devices and with simulation models. This general methodology is explained in detail and is illustrated with two concrete scenarios which are both instances of a common safe formal pattern: one scenario involves the interaction of a provably safe pacemaker with a simulated heart; the other involves the interaction of a safe controller for patient-induced analgesia with a real syringe pump.

description: To synthesise the available evidence relating to best practice in training videofluoroscopy and barium swallow analysts. The review was conducted according to the PRISMA statement and registered in PROSPERO (CRD42017053744). Data were extracted from nine databases. Studies were included if they described training approaches for clinicians or students of any profession learning to interpret videofluoroscopic (VFSS) or barium swallow studies and were written in English. The methods were heterogeneous and a metanalysis was not possible; a narrative review is presented. Sixteen studies were eligible, including those designed to evaluate the influence of training as well as those that described training as part of validating an assessment tool or method. The quality of the studies was assessed with the Hawker scale and assigned an NHMRC rating. While the evidence was low quality (NHMRC level IV), training consistently improved the accuracy and reliability of clinicians and students conducting VFSS. No studies reported the outcome of training for barium swallow analysis. There was significant variability in the dose, method, and setting of training. To elucidate best practice in VFSS analysis to ensure training is cost effective and results in accurate diagnosticians requires further research.

description: The project objective is to design and build an electric remote-control fixed-wing aircraft that maximizes payload capacity for the 2023 Society of Automotive Engineers (SAE) Aero Design West Competition in Fort Worth, Texas. The team placed 24th out of 63 teams at the SAE Aero Design West Competition. The SAE Aero Design competition is a yearly regional competition that “provides students with real-world engineering experience through aircraft design challenges”. The team designed a remote-control aircraft with a 12-foot wingspan utilizing a tapered cylindrical fuselage, Clark Y airfoils for the wing, and NACA 0012 airfoils for the horizontal and vertical stabilizers with the goal of minimizing aircraft weight while maximizing potential payload capacity. During development, design decisions were made based on SolidWorks fluid flow simulation to optimize and verify the aircraft design. The aircraft was manufactured utilizing carefully selected materials to increase performance.

description: A tight correlation between gamma-ray and radio emission is found for a sample of BL Lacertae (BL Lac) objects detected by Fermi Gamma-ray Space Telescope (Fermi) and the Energetic Gamma-Ray Experiment Telescope (EGRET). The gamma-ray emission of BL Lac objects exhibits strong variability, and the detection rate of gamma-ray BL Lac objects is low, which may be related to the gamma-ray duty cycle of BL Lac objects. We estimate the gamma-ray duty cycle ~ 0.11, for BL Lac objects detected by EGRET and Fermi. Using the empirical relation of gamma-ray emission with radio emission and the estimated gamma-ray duty cycle, we derive the gamma-ray luminosity function (LF) of BL Lac objects from their radio LF. Our derived gamma-ray LF of BL Lac objects can almost reproduce that calculated with the recently released Fermi bright active galactic nuclei (AGN) sample. We find that about 45% of the extragalactic diffuse gamma-ray background (EGRB) is contributed by BL Lac objects. Combining the estimate of the quasar contribution to the EGRB in the previous work, we find that about 77% of the EGRB is contributed by BL Lac objects and radio quasars.

Adaptation of inter-limb control during robot-simulated human standing balance
Creators: name: Wang, Philip
Publisher: name: University of British Columbia
Year: 2016

description: Re-learning to maintain standing balance in the presence of a paretic lower limb is important for many stroke survivors. Models of inter-limb adaptations of the central nervous system performing its role as the balance controller can aid the development of post-stroke balance therapies. This thesis quantifies such inter-limb adaptations in healthy participants. Two studies examine whether asymmetrically manipulating the limbs’ contributions to simulated standing balance (i.e., ankle torque gains) using a robotic balance platform can shift balance control toward a targeted limb. In the first study, virtually weakening (decreasing the contribution, or input gain, to the simulation from) a limb in the medial-lateral direction significantly shifted weight distribution, but not anterior-posterior torque variance, towards the virtually weakened limb. Asymmetrically manipulated anterior-posterior limb contributions also did not produce observable changes in torque, despite expectations for the balance controller to adapt and prefer using the virtually strengthened (gain-increased) limb. The second study further investigates manipulating anterior-posterior limb contributions and whether the balance controller is optimally adaptive. The protocol’s torque gain values, unlike those of the previous study, required the balance controller to adopt a new strategy to remain upright. The targeted limb was virtually strengthened by a factor of two (gain of two) while the other limb was virtually reversed (gain of negative one). Two measures of balance contribution were calculated using (1) root mean square torque during quiet stance and (2) the balance controller’s frequency response functions identified during perturbed stance. Over a two-day protocol with gains alternating between normal and manipulated values in each day, significant shifts of balance contributions were observed within and between days. The results demonstrate that the central nervous system can adapt inter-limb balance coordination in the absence of sensory feedback that explicitly communicates the asymmetrical manipulation of the balance dynamics. Anterior-posterior torque gain manipulations show promise as therapy for reducing balance asymmetries, which is crucial for restoring the mobility and independence of stroke survivors. As an additional mode of balance therapy, this novel method may enhance the effectiveness of existing stroke rehabilitation programs. Future work will address the applicability of this protocol to patient populations.

description: Purpose: This study was designed to evaluate the performance of typically developing Swedish-speaking children on DYMTA (Dynamisk Motorisk Talbedömning), a Swedish dynamic motor speech assessment. Method: Participants were 94 children, 45 boys/49 girls (9/8 multilingual), with typical oral motor, speech, and language skills, between 37 and 106 months divided into five age-groups. They performed two speech motor assessments, DYMTA-A and DYMTA-B using dynamic assessment. Result: Typically developing children show good motor speech performance on targeted speech characteristics already at the age of three. DYMTA median total score was high for all ages; 90% of maximum or above. A significant correlation with age was found for DYMTA-A (p = 0.000, r = 0.49) and DYMTA-B (p = 0.000, r = 0.77). No significant differences were found across gender or concerning being mono- or multilingual. Conclusion: DYMTA is the first Swedish assessment tool designed to identify children with CAS. The results of this study demonstrate that typically developing Swedish children perform well on DYMTA and that the test has possible utility for both mono- and multilingual children.

description: We present an electron energy loss study using energy filtered TEM of spatially resolved surface plasmon excitations on a silver nanorod of aspect ratio 14.2 resting on a 30 nm thick silicon nitride membrane. Our results show that the excitation is quantized as resonant modes whose intensity maxima vary along the nanorod's length and whose wavelength becomes compressed towards the ends of the nanorod. Theoretical calculations modelling the surface plasmon response of the silver nanorod-silicon nitride system show the importance of including retardation and substrate effects in order to describe accurately the energy dispersion of the resonant modes.

A magnetic sensor to measure wear in centrifugal pumps
Creators: name: Khoie, Ramin
Publisher: name: University of British Columbia
Year: 2016

description: On average, centrifugal pumps consume between 25% and 60% of the total consumed electrical energy inside process plants. Erosion inside open-impeller centrifugal pumps leads to a reduction in pump efficiency and occasional plant downtime. This work demonstrates a new concept for an online instrument capable of monitoring wear with the objective of improving the maintenance scheduling of centrifugal pumps and the prevention of unexpected failure through a predictive maintenance system. A magnetic wear sensor is designed and fabricated that allows for wear measurement while the pump is in operation. This sensor can be installed on existing centrifugal pumps and does not require any pump modifications. Wear mostly occurs on the tip of the impeller blades reducing the thickness of the impeller which in turn increases the gap width between the impeller and the side plate inside the pump housing, from 0.65 mm (no wear) to 2.50 mm for maximum allowable wear on the pump used for prototyping. By using a magnetic circuit with the pump and its components, wear is estimated by measuring the change in the width of the varying gap between the impeller and the side plate. To assemble the magnetic circuit, a high-permeability clamping mechanism with a relative permeability of 10,000 is designed and fabricated along with a magnetic coil excited using a 1.0 V AC voltage signal at 70 Hz to drive flux through the circuit. As wear occurs, the total reluctance of the magnetic circuit increases causing the inductance of the coil to drop. The coil's inductance is also a function of the impeller's angular position. To estimate wear, data is collected at a sampling frequency of 500 kHz and then assessed in the frequency domain after fast Fourier transform (FFT). The amplitude of the FFT signal at the frequency correlated with the pump's rotational speed is then considered to estimate wear. For a data sampling time of one second the sensor has a signal to noise ratio of 17.8 dB with an average sensitivity of 0.022 mV/mm and a resolution of 0.38 mm.

description: A series of simulations aimed at elucidating the self-assembly dynamics of spherical virus capsids is described. This little-understood phenomenon is a fascinating example of the complex processes that occur in the simplest of organisms. The fact that different viruses adopt similar structural forms is an indication of a common underlying design, motivating the use of simplified, low-resolution models in exploring the assembly process. Several versions of a molecular dynamics approach are described. Polyhedral shells of different sizes are involved, the assembly pathways are either irreversible or reversible, and an explicit solvent is optionally included. Model design, simulation methodology and analysis techniques are discussed. The analysis focuses on the growth pathways and the nature of the intermediate states, properties that are hard to access experimentally. Among the key observations are that efficient growth proceeds by means of a cascade of highly reversible stages, and that while there are a large variety of possible partial assemblies, only a relatively small number of strongly bonded configurations are actually encountered.

description: Purpose: This study aimed to understand the knowledge, attitudes and beliefs of early childhood health and education professionals on bilingualism and heritage language maintenance for children with language delay, and how their interactions with caregivers may influence the decision-making process to maintain or not maintain speaking heritage languages with children. Method: A qualitative methodology was used to explore the research aims. Seven early childhood health and education professionals with experience working with bilingual families participated in in-depth interviews. Data were analysed using a grounded theory approach and a symbolic interactionism theoretical framework. Result: Understandings of bilingualism and language development were strongly influenced by socially and culturally contextualised factors, such as the linguistic context in Australia. Barriers and facilitators to supporting bilingualism and helping caregivers make informed choices included: unique child and family characteristics, the level of trust in professional advice, and the level of professional agency to support knowledge and practice. Conclusion: Findings highlighted the need to focus on the processes involved in supporting caregivers to make informed decisions about bilingualism and heritage language maintenance for children with language delay. The need for professional development on bilingualism and language development for early childhood health and education professionals was also highlighted.

description: We have studied the microwave electrodynamics of single crystal iron-based superconductors Ba$_{0.72}$K$_{0.28}$Fe$_2$As$_2$ (hole-doped, $T_\mathrm{c}$ $\approx $30 K) and Ba(Fe$_{0.95}$Co$_{0.05}$)$_2$As$_2$ (electron-doped, $T_\mathrm{c}$ $\approx$20 K), by cavity perturbation and broadband spectroscopy. SQUID magnetometry was used to confirm the quality and homogeneity of the samples under study. Through cavity perturbation techniques, the temperature dependence of the in-plane London penetration depth $Δλ(T)$, and therefore the superfluid phase stiffness $λ^2(0)/λ^2(T)$ was measured. Down to 0.4 K, the data do not show the exponential saturation at low temperatures expected from a singly-, fully-gapped superconductor. Rather, both the electron- and the hole-doped systems seem to be best described by a power law behavior, with $λ^2(0)/λ^2(T)$ $\sim$ $T^n$ and \emph{n} $\approx$ 2.5. In the three samples we studied, a weak feature near the sensitivity limit of our measurements appears near $T/T_\mathrm{c}$ =~0.04, hinting at a corresponding low energy feature in the superconducting density of states. The data can also be relatively well-described by a simple two-gap s-wave model of the order parameter, but this yields parameters which seem unrealistic and dependent on the fit range. Broadband surface resistance measurements reveal a sample dependent residual loss whose origin is unclear. The data from the \FeAs samples can be made to scale as $ω^2$ if the extrinsic loss is treated as an additive component, indicating large scattering rates. Finally, the temperature dependence of the surface resistance at 13 GHz obeys a power law very similar to those observed for $Δλ(T)$.

description: We solve the eigenvalue problem of the $D_N$ type of Calogero model by mapping it to a set of decoupled quantum harmonic oscillators through a similarity transformation. In particular, we construct the eigenfunctions of this Calogero model from those of bosonic harmonic oscillators having either all even parity or all odd parity. It turns out that the eigenfunctions of this model are orthogonal with respect to a nontrivial inner product, which can be derived from the quasi-Hermiticity property of the corresponding conserved quantities.

Decay of nuclear hyperpolarization in silicon microparticles

description: We investigate the low-field relaxation of nuclear hyperpolarization in undoped and highly doped silicon microparticles at room temperature following removal from high field. For nominally undoped particles, two relaxation time scales are identified for ambient fields above 0.2 mT. The slower, T_1s, is roughly independent of ambient field; the faster, T_1f, decreases with increasing ambient field. A model in which nuclear spin relaxation occurs at the particle surface via a two-electron mechanism is shown to be in good agreement with the experimental data, particularly the field-independence of T_1s. For boron-doped particles, a single relaxation time scale is observed. This suggests that for doped particles, mobile carriers and bulk ionized acceptor sites, rather than paramagnetic surface states, are the dominant relaxation mechanisms. Relaxation times for the undoped particles are not affected by tumbling in a liquid solution.

Plethysms, replicated Schur functions and series, with applications to vertex operators

description: Specializations of Schur functions are exploited to define and evaluate the Schur functions s_λ[αX] and plethysms s_λ[αs_ν(X))] for any α- integer, real or complex. Plethysms are then used to define pairs of mutually inverse infinite series of Schur functions, M_πand L_π, specified by arbitrary partitions π. These are used in turn to define and provide generating functions for formal characters, s_λ^{(π)}, of certain groups H_π, thereby extending known results for orthogonal and symplectic group characters. Each of these formal characters is then given a vertex operator realization, first in terms of the series M=M_{(0)} and various L_σ^\perp dual to L_σ, and then more explicitly in exponential form. Finally the replicated form of such vertex operators are written down.

description: We present the first aperture synthesis unbiased spectral line survey toward an extragalactic object. The survey covered the 40 GHz frequency range between 202 and 242 GHz of the 1.3 mm atmospheric window. We find that 80% of the observed band shows molecular emission, with 73 features identified from 15 molecular species and 6 isotopologues. The 13C isotopic substitutions of HC3N and transitions from H2(18)O, 29SiO, and CH2CO are detected for the first time outside the Galaxy. Within the broad observed band, we estimate that 28% of the total measured flux is due to the molecular line contribution, with CO only contributing 9% to the overall flux. We present maps of the CO emission at a resolution of 2.9"x1.9" which, though not enough to resolve the two nuclei, recover all the single-dish flux. The 40 GHz spectral scan has been modelled assuming LTE conditions and abundances are derived for all identified species. The chemical composition of Arp 220 shows no clear evidence of an AGN impact on the molecular emission but seems indicative of a purely starburst-heated ISM. The overabundance of H2S and the low isotopic ratios observed suggest a chemically enriched environment by consecutive bursts of star formation, with an ongoing burst at an early evolutionary stage. The large abundance of water (~10^-5), derived from the isotopologue H2(18)O, as well as the vibrationally excited emission from HC3N and CH3CN are claimed to be evidence of massive star forming regions within Arp 220. Moreover, the observations put strong constraints on the compactness of the starburst event in Arp 220. We estimate that such emission would require ~2-8x10^6 hot cores, similar to those found in the Sgr B2 region in the Galactic center, concentrated within the central 700 pc of Arp 220.

Community Detection via Semi-Synchronous Label Propagation Algorithms

description: A recently introduced novel community detection strategy is based on a label propagation algorithm (LPA) which uses the diffusion of information in the network to identify communities. Studies of LPAs showed that the strategy is effective in finding a good community structure. Label propagation step can be performed in parallel on all nodes (synchronous model) or sequentially (asynchronous model); both models present some drawback, e.g., algorithm termination is nor granted in the first case, performances can be worst in the second case. In this paper, we present a semi-synchronous version of LPA which aims to combine the advantages of both synchronous and asynchronous models. We prove that our models always converge to a stable labeling. Moreover, we experimentally investigate the effectiveness of the proposed strategy comparing its performance with the asynchronous model both in terms of quality, efficiency and stability. Tests show that the proposed protocol does not harm the quality of the partitioning. Moreover it is quite efficient; each propagation step is extremely parallelizable and it is more stable than the asynchronous model, thanks to the fact that only a small amount of randomization is used by our proposal.

description: We aimed to investigate the correlation between blood homocysteine (Hcy) levels and pre-eclampsia (PE) risk in pregnant women. Related articles were searched using PubMed, Embase, and Web of Science databases. Methodological quality of included studies was evaluated using the Newcastle-Ottawa Quality Assessment Scale (NOS). Cochran's Q and I2 tests were used to evaluate heterogeneity. Egger’s test was used to evaluate publication bias. A sensitivity analysis was performed to test stability of the results using a one-by-one elimination method. Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) was used to assess certainty of evidence. Nine studies (4384 PE and 26021 non-PE patients) were included in the meta-analysis. The methodology of them was of good quality, with NOS scores of 5–8. However, there was a significant heterogeneity among included studies. Therefore, the random effect model was generated and combined results suggested a significant association between increased level of Hcy in pregnant women and PE risk. Although a significant publication bias was found in the current study with a P value of 0.006 in the Egger test, sensitivity analysis showed that the combined results were stable and did not vary significantly from any single study. However, the GRADE evidence quality was very low, which may lower the recommendation of pooled results. Increased levels of Hcy in maternal blood were significantly associated with the risk of PE, but low certainty of evidence need to be improved by more high-quality studies.
Improved bounds for CFT's with global symmetries

description: The four point function of Conformal Field Theories (CFT's) with global symmetry gives rise to multiple crossing symmetry constraints. We explicitly study the correlator of four scalar operators transforming in the fundamental representation of a global SO(N) and the correlator of chiral and anti-chiral superfields in a superconformal field theory. In both cases the constraints take the form of a triple sum rule, whose feasibility can be translated into restrictions on the CFT spectrum and interactions. In the case of SO(N) global symmetry we derive bounds for the first scalar singlet operator entering the Operator Product Expansion (OPE) of two fundamental representations for different value of N. Bounds for the first scalar traceless-symmetric representation of the global symmetry are computed as well. Results for superconformal field theories improve previous investigations due to the use of the full set of constraints. Our analysis only assumes unitarity of the CFT, crossing symmetry of the four point function and existence of an OPE for scalars.
