An analysis of need assessment in the mental health context
Creators: name: Farrally, Vicki Lea
Publisher: name: University of British Columbia
Year: 2010

description: Need assessment methods grew out of the Community Mental Health Centre movement. Developed during a time of rapid expansion of service, there was a focus on providing services matched to the unique needs of a community. In the following years need assessment further developed as a technology and a search began for a "best model'. This paper argues that a "best model' is illusionary, a "best fit' being a more desirable goal. As fiscal constraints have reduced the resources available to consumption Ministries such as Health, need assessment has been increasingly used an allocative tool. Users of the tool, it is argued, must therefore choose their model with care and an understanding of the values and concepts inherent in each model is seen as necessary for intelligent choice. Finally, an examination of the British Columbia mental health context offers an analysis of some of the factors which have and will affect the use of need assessment in this Province

description: Newton's method for solving the matrix equation $F(X)\equiv AX-XX^TAX=0$ runs up against the fact that its zeros are not isolated. This is due to a symmetry of $F$ by the action of the orthogonal group. We show how differential-geometric techniques can be exploited to remove this symmetry and obtain a ``geometric'' Newton algorithm that finds the zeros of $F$. The geometric Newton method does not suffer from the degeneracy issue that stands in the way of the original Newton method.

description: Provision of some autonomous functions to an agricultural vehicle would lighten the job of the operator but in doing so, the accuracy should not be lost to still obtain an optimal yield. Autonomous navigation of an agricultural vehicle involves the control of different dynamic subsystems, such as the yaw angle dynamics and the longitudinal speed dynamics. In this study, a proportional-integral-derivative controller is used to control the longitudinal velocity of the tractor. For the control of the yaw angle dynamics, a proportional-derivative controller works in parallel with a type-2 fuzzy neural network. In such an arrangement, the former ensures the stability of the related subsystem, while the latter learns the system dynamics and becomes the leading controller. In this way, instead of modeling the interactions between the subsystems prior to the design of model-based control, we develop a control algorithm which learns the interactions online from the measured feedback error. In addition to the control of the stated subsystems, a kinematic controller is needed to correct the errors in both the x- and the y- axis for the trajectory tracking problem of the tractor. To demonstrate the real-time abilities of the proposed control scheme, an autonomous tractor is equipped with the use of reasonably priced sensors and actuators. Experimental results show the efficacy and efficiency of the proposed learning algorithm.

description: Prospects to search for a new massless neutral gauge boson, the paraphoton, in e+ e- collisions at center-of-mass energies of 0.5 and 1 TeV are studied. The paraphoton naturally appears in models with abelian kinetic mixing. A possible realistic model independent lowest order effective Lagrangian contains magnetic interactions of the paraphoton with the Standard Model fermion fields. These interactions are proportional to the fermion mass and grow with energy, with however very weak paraphoton couplings to ordinary matter. At the ILC, a potentially interesting process to search for the paraphoton is its radiation off top quarks, so that the event topology to be searched for is a pair of acoplanar top quark jets with missing energy. By combining many discriminating features of signal and background events efficient paraphoton event selection was achieved allowing to set limits for the top-paraphoton coupling. Arguments in favor of the missing energy as the paraphoton with spin 1 are discussed.

description: A three-dimensional topological insulator features a two-dimensional surface state consisting of a single linearly-dispersive Dirac cone. Under broken time-reversal symmetry, the single Dirac cone is predicted to cause half-integer quantization of Hall conductance, which is a manifestation of the parity anomaly in quantum field theory. However, despite various observations of quantization phenomena, the half-integer quantization has been elusive because a pair of equivalent Dirac cones on two opposing surfaces are simultaneously measured in ordinary experiments. Here we demonstrate the half-integer quantization of Hall conductance in a synthetic heterostructure termed a 'semi-magnetic' topological insulator, where only one surface state is gapped by magnetic doping and the opposite one is non-magnetic and gapless. We observe half quantized Faraday/Kerr rotations with terahertz magneto-optical spectroscopy and half quantized Hall conductance in transport at zero magnetic field. Our results suggest a condensed-matter realization of the parity anomaly and open a way for studying unconventional physics enabled by a single Dirac fermion.

description: We analyze the 11-year long-term light curve of the Radio-loud Narrow-line Seyfert 1 (NLSy1) galaxy J0849+5108 and the nearly simultaneous $γ$-ray data of the source. The data were obtained with the Owens Valley Radio Observatory 40-m telescope at 15~GHz and with the Large Area Telescope onboard Fermi Gamma-ray Space Telescope, respectively. A quasi-periodic oscillation (QPO) signal at a significance of $>$5$σ$ is found in the radio light curve, but no similar modulation is seen in the $γ$-ray light curve. The QPO signal was present for 21 cycles, the longest among the reported radio QPOs, and likely disappeared after 2019 January 16. Different mechanisms proposed to explain the observed QPOs in Active Galactic Nuclei (AGN) are discussed for this QPO case. Either a secular instability in the inner accretion disk or a helical structure in the jet of J0849+5108 may explain the radio QPO, while for the latter scenario the jet has to be collimated up to $\sim$200~pc, similar to that seen in the nearby AGN M87. It will be of interests to keep monitoring the source at radio frequencies, seeing if similar QPO signals would appear again or not.

description: Neural saturation in Deep Neural Networks (DNNs) has been studied extensively, but remains relatively unexplored in Convolutional Neural Networks (CNNs). Understanding and alleviating the effects of convolutional kernel saturation is critical for enhancing CNN models classification accuracies. In this paper, we analyze the effect of convolutional kernel saturation in CNNs and propose a simple data augmentation technique to mitigate saturation and increase classification accuracy, by supplementing negative images to the training dataset. We hypothesize that greater semantic feature information can be extracted using negative images since they have the same structural information as standard images but differ in their data representations. Varied data representations decrease the probability of kernel saturation and thus increase the effectiveness of kernel weight updates. The two datasets selected to evaluate our hypothesis were CIFAR- 10 and STL-10 as they have similar image classes but differ in image resolutions thus making for a better understanding of the saturation phenomenon. MNIST dataset was used to highlight the ineffectiveness of the technique for linearly separable data. The ResNet CNN architecture was chosen since the skip connections in the network ensure the most important features contributing the most to classification accuracy are retained. Our results show that CNNs are indeed susceptible to convolutional kernel saturation and that supplementing negative images to the training dataset can offer a statistically significant increase in classification accuracies when compared against models trained on the original datasets. Our results present accuracy increases of 6.98% and 3.16% on the STL-10 and CIFAR-10 datasets respectively.

Factors affecting timing and size of runs of hilsa shad (Hilsa ilisha) in Bangladesh and Pakistan
Creators: name: Das, Nitya Nanda
Publisher: name: University of British Columbia
Year: 2010

description: Data were gathered in 1983 and 1984 on the Hilsa fishery in the Meghna River in Bangladesh, and on factors related to its seasonal variation, including effort as estimated by weekly counts of fishing boats, and landings as estimated by counts of fish offloaded at Chandpur. Historical data were also analyzed concerning factors influencing annual variations in Hilsa landings from the Padma River of the Ganges (1967-1974) and from the Indus River of Pakistan (1968-1982). Rail shipments were good indicators of landings. No significant relationship was observed between riverine Hilsa landings and fishing intensity. Rainfall, mean water level and maximum air temperature had no obvious influence on annual variations in seasonal timing of Hilsa runs in the Padma river of the Ganges. Rainfall two years earlier had a significant negative relationship with annual variation of Hilsa landings, in both the Padma River and in the Indus River. Mechanisms regulating this negative association between landings and rainfall may be that Hilsa are 1+ year old when they are first recruited to the fishery, and the survival of eggs and fry is minimum in years when there is a very high rainfall. In the Ganges and Indus rivers, annual landings were not closely correlated, and appear to be dependent in part on earlier rainfall conditions within each region. This dependency offers a means of rough forecast of annual harvest on the basis of previous rainfall data.

description: We present a study of VO2 in the rutile and monoclinic (M1) phases by means of all-electron full-potential LMTO GW calculation. Full frequency dependence and the off-diagonal matrix elements of the self-energy are taken into account. As a result of dynamical correlation, a satellite structure is found above the $t_{2g}$ quasiparticle peak but not below, in both the rutile and monoclinic phases. For the monoclinic structure, the insulating state is not obtained within the usual 1-shot GW calculation. We perform a simplified "self-consistent" GW scheme by adding a uniform shift to the conduction band levels and recalculating the quasiparticle wavefunctions accordingly. An insulating solution with a gap of approximately 0.6 eV is obtained, in agreement with experiments.

description: We revisit the problem of surface states in semiconductors with inverted band structures, such as $α$-Sn and HgTe. We unravel the confusion that arose over the past decade regarding the origin of the surface states, their topological nature, and the role of strain. Within a single minimalistic description, we reconcile different solutions found in the 1980s with the results obtained from modern-day numerical simulations, allowing us to unambiguously identify all branches of surface states around the $Γ$-point of the Brillouin zone in different regimes. We also show that strain is a smooth "deformation" to the surface states, following the usual continuity principle of physics, and not leading to any drastic change of the physical properties in these materials, in contrast to what has recently been advanced in the literature. We consider biaxial in-plane strain that is either tensile or compressive, leading to different branches of surface states for topological insulators and Dirac semimetals, respectively. Our model can help in interpreting numerous experiments on topological surface states originating from inverted-band semiconductors.

description: Total precession (geodetic precession and frame dragging) depends on the velocity of each source of gravitation, which means that it depends on the choice of the coordinate system. We consider the latter as an anomaly specifically in the Gravity Probe B experiment, we investigated it and solved this anomaly. Thus, we proved that if our present expression for the geodetic precession is correct, then the frame dragging should be 25% less than its predicted value.

description: Restricted Boltzmann machines (RBM) and deep Boltzmann machines (DBM) are important models in machine learning, and recently found numerous applications in quantum many-body physics. We show that there are fundamental connections between them and tensor networks. In particular, we demonstrate that any RBM and DBM can be exactly represented as a two-dimensional tensor network. This representation gives an understanding of the expressive power of RBM and DBM using entanglement structures of the tensor networks, also provides an efficient tensor network contraction algorithm for the computing partition function of RBM and DBM. Using numerical experiments, we demonstrate that the proposed algorithm is much more accurate than the state-of-the-art machine learning methods in estimating the partition function of restricted Boltzmann machines and deep Boltzmann machines, and have potential applications in training deep Boltzmann machines for general machine learning tasks.

description: We present Very Large Array images of a "Double-Double Radio Galaxy", a class of objects in which two pairs of lobes are aligned either side of the nucleus. In this object, B0925+420, we discover a third pair of lobes, close to the core and again in alignment with the other lobes. This first-known "Triple-Double" object strongly increases the likelihood that these lobes represent mutiple episodes of jet activity, as opposed to knots in an underlying jet. We model the lobes in terms of their dynamical evolution. We find that the inner pair of lobes is consistent with the outer pair having been displaced buoyantly by the ambient medium. The middle pair of lobes is more problematic - to the extent where an alternative model interpreting the middle and inner "lobes" as additional bow shocks within the outer lobes may be more appropriate - and we discuss the implications of this on our understanding of the density of the ambient medium.

description: This work builds a unified framework for the study of quadratic form distance measures as they are used in assessing the goodness of fit of models. Many important procedures have this structure, but the theory for these methods is dispersed and incomplete. Central to the statistical analysis of these distances is the spectral decomposition of the kernel that generates the distance. We show how this determines the limiting distribution of natural goodness-of-fit tests. Additionally, we develop a new notion, the spectral degrees of freedom of the test, based on this decomposition. The degrees of freedom are easy to compute and estimate, and can be used as a guide in the construction of useful procedures in this class.

description: Particles, including micro particles, spherical and non-spherical, play important roles in many fields. The major goals in designing these particles include controlling particle monodispersity, chemistry, porosity, shape and size. Therefore, there is a continuous demand for controllable technologies and equipment for the engineering of such particles. Despite the traditional methods for particles production, droplet microfluidics technique is promising method for the production of monodisperse emulsion droplets one at a time with tailored sizes, shapes and morphologies. These emulsion drops can be used for the precise manufacturing of novel particles, such as microcapsules, Janus or patchy particles and porous particles with tailored internal structures. In general, highly monodisperse emulsion droplets are produced in microfluidic device and are used as templates and then solidified to form microparticles by solidification methods. For example, single emulsion drops can be a template for microspheres and double emulsion can be a template for coreshell microparticles, Janus and other morphologies.In this study, two-phase and three-phase glass capillary microfluidic devices were utilized for the formation of single emulsions and double emulsions respectively. Solidification methods used were photopolymerisation of photocurable monomer/polymer and solvent evaporation. Single emulsions of O/W and W/O were used as templates for the fabrication of porous and non-porous microspheres and Janus microparticles. Whereas double emulsions were used as templates for the formation of core-shell microparticles. The size of the produced droplets, the frequency of droplet generation and the size distribution were precisely controlled by adjusting fluids flow rates and orifice diameter of the collection capillary. In addition, to add functionality to the microparticles, nanoparticles such as TiO2 , magnetic Fe(II,III)Oxide and graphene were added separately to the polymer solutions. Two droplet formation modes were observed during droplet generation process in the microfluidic devices, dripping and jetting where uniform droplets (CV < 3%) were produced in the dripping mode. Microparticles fabricated in this work were: microspheres and core-shell microparticles of TiO2 /poly(HDDA) and graphene/poly(HDDA), PS/PVAC magnetic Janus microparticles and PEGDA , TiO2 /PEGDA and graphene/PEGDA microgels.The fabricated microparticles were characterised using SEM, ATR-FTIR, DSC, XRD, FIB and confocal microscopy.
Large regular QCD coupling at Low Energy?

description: The issue is the expediency of the QCD notions use in the low energy region down to the confinement scale, and, in particular, the efficacy of the QCD invariant coupling \barα_s(Q^2) with a minimal analytic modification in this domain. To this goal, we overview a quite recent progress in application of the ghost-free Analytic Perturbative Theory approach (with no adjustable parameters) for QCD in the region below 1 GeV. Among them the Bethe--Salpeter analysis of the meson spectra and spin-dependent (polarization) Bjorken sum rule. The impression is that there is a chance for the theoretically consistent and numerically correlated description of hadronic events from Z_0 till a few hundred MeV scale by combination of analytic pQCD and some explicit non-perturbative contribution in the spirit of duality. This is an invitation to the practitioner community for a more courageous use of ghost-free QCD coupling models for data analysis in the low energy region.

We formally prove within the proposed framework, that the set of results about invariant synchrony patterns for unweighted networks also holds for the weighted case. Moreover, the approach described allows us to reason about any multiedge and multiedge-type network as if it was single edge and single-edge-type. Several examples illustrate the concepts described. Additionally, an improvement of the coarsest invariant refinement algorithm to find balanced partitions is presented that exhibits a worst-case complexity of $ \mathbf{O}(\vert\mathcal{C}\vert^3) $, where $\mathcal{C}$ denotes the set of cells.

Aspects of the reproductive biology of Strombus gigas
Creators: name: Egan, Brian Denis
Publisher: name: University of British Columbia
Year: 2010

description: Shell morphology changes relating to sexual maturity and the reproductive cycle of Strombus gigas were studied at a single site within the Barrier Reef lagoon of Belize, Central America. Monthly samples, from July 1981 to June 1983, of transverse tissue sections, through the digestive gland and gonad, were fixed for examination by light microscopy. Sections from all areas of the gonad were used to develop a sexual maturity scale that would permit the maturity of a specimen to be determined from the condition of a single tissue sample. The effectiveness of the technique described, for use in other meso- or neogastropods, is dependent on simultaneous maturation throughout the gonad and on an even distribution of reproductive structures within. Sexual maturity in S. gigas (as defined by the development of mature gametes) first occurs when individuals have a flaring shell lip-thickness of approximately 4 mm. Sexual maturity is reached approximately 1 year after maximum shell length is reached and approximately 6 months after development of the flaring lip, at an age of roughly 4 years. Ninety four percent of the population studied attained the legal shell length, in Belize, of 175 mm. The time delay between attaining legal length and becoming sexually mature means that there is a period, for 94% of the population, when they may be legally harvested before becoming sexually mature. Reproductive activity occurs year-round in the population studied. An annual pattern of activity was not apparent through inspection of the data alone. No statistical correlation was found between gonadal activity and average monthly air temperature or monthly rainfall.

description: Recent advances in deep convolutional neural networks (DCNNs) have shown impressive performance improvements on thermal to visible face synthesis and matching problems. However, current DCNN-based synthesis models do not perform well on thermal faces with large pose variations. In order to deal with this problem, heterogeneous face frontalization methods are needed in which a model takes a thermal profile face image and generates a frontal visible face. This is an extremely difficult problem due to the large domain as well as large pose discrepancies between the two modalities. Despite its applications in biometrics and surveillance, this problem is relatively unexplored in the literature. We propose a domain agnostic learning-based generative adversarial network (DAL-GAN) which can synthesize frontal views in the visible domain from thermal faces with pose variations. DAL-GAN consists of a generator with an auxiliary classifier and two discriminators which capture both local and global texture discriminations for better synthesis. A contrastive constraint is enforced in the latent space of the generator with the help of a dual-path training strategy, which improves the feature vector discrimination. Finally, a multi-purpose loss function is utilized to guide the network in synthesizing identity preserving cross-domain frontalization. Extensive experimental results demonstrate that DAL-GAN can generate better quality frontal views compared to the other baseline methods.

Team Contract Group Activity
Creators: name: Shulse, Christine
Publisher: name: QUBES Educational Resources
Year: 2025

description: The Team Contract Group Activity guides students in setting positive guidelines for their group work on a project about environmental health. The contract addresses expectations around meetings, communication, conflict, and more. Using psychologist Bruce Tuckman’s stages of team development as a framework, this activity is designed to help teams move from the storming to the norming phase.

This activity for biology courses involves (1) recalling prior knowledge about environmental health and climate change; (2) a video on cultivating collaboration; (3) six prompts to build the team contract; (4) reflection and sharing about motivations; and (5) a final survey to determine what works for students.
How Real are Liquid Groundstates? Ultra-Fast Crystal Growth and the Susceptibility of Energy Minima in Liquids
Creators: name: Sun, Gang
name: Harrowell, Peter
Publisher: name: arXiv
Year: 2021
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: We calculate the degree to which the final structure of the local groundstate in a liquid is a function of the strength of a perturbing potential applied during energy minimization. This structural susceptibility is shown to correlate well with the observed tendency of liquid adjacent to a crystal interface to exhibit a crystalline groundstate, a feature that has been strongly linked to the observation of ultra-fast crystal growth in pure metals and ionic melts. It is shown that the structural susceptibility increases dramatically as the interaction potential between atoms is softened.
Spontaneous spin accumulation in singlet-triplet Josephson junctions

Year: 2008
Subjects: subject: Superconductivity (cond-mat.supr-con)

description: We study the Andreev bound states in a Josephson junction between a singlet and a triplet superconductors. Because of the mismatch in the spin symmetries of pairing, the energies of the spin up and down quasiparticles are generally different. This results in imbalance of spin populations and net spin accumulation at the junction in equilibrium. This effect can be detected using probes of local magnetic field, such as the scanning SQUID, Hall, and Kerr probes. It may help to identify potential triplet pairing in $\rm(TMTSF)_2X$, $\rm Sr_2RuO_4$, and oxypnictides.

description: We present maps classifying regions of the sky according to their information gain potential as quantified by the Fisher information. These maps can guide the optimal retrieval of relevant physical information with targeted cosmological searches. Specifically, we calculate the response of observed cosmic structures to perturbative changes in the cosmological model and chart their respective contributions to the Fisher information. Our physical forward modeling machinery transcends the limitations of contemporary analyses based on statistical summaries to yield detailed characterizations of individual 3D structures. We demonstrate this using galaxy counts data and showcase the potential of our approach by studying the information gain of the Coma cluster. We find that regions in the vicinity of the filaments and cluster core, where mass accretion ensues from gravitational infall, are the most informative about our physical model of structure formation in the Universe. Hence, collecting data in those regions would be most optimal for testing our model predictions. The results presented in this work are the first of their kind and elucidate the inhomogeneous distribution of cosmological information in the Universe. This study paves a new way forward to perform efficient targeted searches for the fundamental physics of the Universe, where search strategies are progressively refined with new cosmological data sets within an active learning framework.

School Leaders’ Experiences of Knowledge Management in a Swiss Private School: An Interpretative Phenomenological Analysis
Creators: name: Robbins, Steven
Publisher: name: University of Leicester
Year: 2021
Subjects: Uncategorized

description: This thesis provides an in-depth exploration of the perceptions and lived experiences of school leaders in the context of a private Swiss international school. It aims to explore how school leaders perceive the phenomenon of knowledge management and the enablers and barriers to its practice, a new area of study that is under-researched. Semi-structured interviews were carried out remotely using self-transcribing and selfvalidating methods with eight participating school leaders who shared similar job descriptions and responsibilities. The transcripts were analysed using Interpretative Phenomenological Analysis (IPA) and respecting the hermeneutical approach described by Heidegger. Three super-ordinate themes emerged from the analysis: ‘common language and professional development’, ‘socialisation and knowledge flow’ and ‘behaviour’. These themes reveal qualities and behaviours as well as pragmatic considerations for knowledge management that are supported in the literature and that can be applied in schools by school leaders. Discussions of the findings lead to a synthesis of the school leaders’ perspectives and the VISION illustration of knowledge management and school leadership. This crystallisation of the school leaders’ experiences is presented as both a theoretical illustration, offering qualities that could be developed in school leadership at the heart of any KM practice but also as practical means for implementing a KM strategy. Through a comparison with concepts arising in the literature, the emerging themes from the study are given greater depth of understanding with regard to their application for school leaders. This thesis reveals a number of implications of knowledge management practices for school leadership from an area of research that has been limited to the business industry for the last 30 years. I conclude by stressing how important it is for school leaders to implement knowledge management practices and I make suggestions for further research and training possibilities. The syntheses of currently available literature on the subject of knowledge management, the findings and discussions of implications may be of interest to aspiring or practicing school leaders.

description: We consider the realization of quantum Fredkin gate with only linear optics and single photons. First we construct a heralded Fredkin gate using four heralded controlled-not (CNOT) gates. Then we simplify this method to a post-selected one utilizing only two CNOT gates. We also give a possible realization of this method which is feasible with current experimental technology. Another post-selected scheme requires time entanglement of the input photons but needs no ancillary photons.

Grazielia

description: 2.1. Genus Grazielia
Four species of Grazielia were sampled and analyzed in this study. 68 compounds were identified in the VOs obtained from the species in this genus, amounting to 87.6–99.9% of the VOs. All the VOs obtained from the leaves and/or inflorescences of the species in this genus were characterized by the predominance of hydrocarbon monoterpenes (63.8–80.1%) with the same compounds being identified among the major constituents of all the samples. In the VOs obtained from the branches of G. nummularia (Hook. & Arn.) R.M.King & H.Rob a lower percentage of monoterpenes was present.

description: Sustainable urban design or planning is not a LEGO-like assembly of prefabricated elements, but an embryo-like growth with persistent differentiation and adaptation towards a coherent whole. The coherent whole has a striking character - called living structure - that consists of far more small substructures than large ones. To detect the living structure, natural streets or axial lines have been previously adopted to be topologically represent an urban environment as a coherent whole. This paper develops a new approach to detecting the underlying living structure of urban environments. The approach takes an urban environment as a whole and recursively decomposes it into meaningful subwholes at different levels of hierarchy or scale ranging from the largest to the smallest. We compared the new approach to natural street and axial line approaches and demonstrated, through four case studies, that the new approach is better and more powerful. Based on the study, we further discuss how the new approach can be used not only for understanding, but also for effectively designing or planning the living structure of an urban environment to be more living or more livable.
