Plasma lipid variations in response to diet and exercise
Creators: name: McKenzie, Donald Chisholm
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this study was to determine the plasma lipid variations during periods of low calorie diet and low calorie diet plus increased physical activity. Four male graduate students, with above normal activity levels, volunteered for the 10 week study which was divided into five experimental periods. The first, or control condition involved a two week period during which the subjects received a regular diet of normal foods equivalent to approximately 3600 calories per day. During this period 'normal' activity was maintained. The second treatment condition involved a 10 day period of a low calorie diet, with continued 'normal' activity. The low calorie diet was equivalent to approximately 1800 calories daily, of natural foods, plus one multiple vitamin pill. The third experimental period was similar to the control period; a two week period during which the subjects received approximately 4000 calories, per day, of the regular diet. Again, 'normal' activity was maintained. The fourth treatment condition was identical to the second experimental period with the additional requirement of increased daily energy expenditure, per subject, of 500 calories. The final experimental period consisted of a two week period of the regular diet with 'normal' activity. Blood samples were taken, following an overnight fast, twice during each experimental period: once mid-way through the period and again at the end. Plasma triglyceride and free fatty acid concentrations were measured in duplicate in each sample. The results of orthogonal comparisons among treatment means showed a statistically significant increase in the plasma free fatty acid concentration during the low calorie diet and the low calorie diet plus exercise treatment conditions. Increased mobilization of free fatty acids from adipose tissue triglycerides in response to the insufficient dietary supply of substrates for metabolism was cited as the mechanism responsible for the rise in free fatty acid concentration. Neuman-Keuls method was used to examine the effect of the increased physical activity during the low calorie diet periods; the results showed that the increased physical activity had no significant effect on the plasma free fatty acids. Similar statistical procedures applied to the plasma triglyceride values showed a significant decrease in the plasma triglyceride concentration during the low calorie diet and the low calorie diet plus increased physical activity periods. The stress of the low calorie diet on the habitually active subjects was responsible for the decreased levels. The lipid and carbohydrate content of the normal and the low calorie diets, as well as increased peripheral uptake of triglycerides, were suggested as possible explanations for the plasma triglyceride changes. The additional daily output of 500 Calories during the second stress condition was not of sufficient magnitude to elicit a further decrease in plasma triglyceride concentration.

description: Under mild assumptions on the kernel, we obtain the best known error rates in a regularized learning scenario taking place in the corresponding reproducing kernel Hilbert space (RKHS). The main novelty in the analysis is a proof that one can use a regularization term that grows significantly slower than the standard quadratic growth in the RKHS norm.

description: We present a kind of generalized Vaidya solutions in a generic Lovelock gravity. This solution generalizes the simple case in Gauss-Bonnet gravity reported recently by some authors. We study the thermodynamics of apparent horizon in this generalized Vaidya spacetime. Treating those terms except for the Einstein tensor as an effective energy-momentum tensor in the gravitational field equations, and using the unified first law in Einstein gravity theory, we obtain an entropy expression for the apparent horizon. We also obtain an energy expression of this spacetime, which coincides with the generalized Misner-Sharp energy proposed by Maeda and Nozawa in Lovelock gravity.

description: Model Production Function chronology uses dynamic models of the Main Belt Asteroids (MBAs) and Near Earth Objects (NEOs) to derive the impactor flux to a target body. This is converted into the crater size-frequency-distribution for a specific planetary surface, and calibrated using the radiometric ages of different regions of the Moon's surface. This new approach has been applied to the crater counts on Mariner 10 images of the highlands and of several large impact basins on Mercury. MPF estimates for the plains show younger ages than those of previous chronologies. Assuming a variable uppermost layering of the Hermean crust, the age of the Caloris interior plains may be as young as 3.59 Ga, in agreement with MESSENGER results that imply that long-term volcanism overcame contractional tectonics. The MPF chronology also suggests a variable projectile flux through time, coherent with the MBAs for ancient periods and then gradually comparable also to the NEOs.

Attention bias in social anxiety : are there mitigating effects of self-affirmation?
Creators: name: McCarthy, SL
Publisher: name: University Of Tasmania
Year: 2023

description: A number of studies have indicated that Self-Affirmation (SA) manipulation plays a role in decreasing an attention bias toward threatening information, especially when there is a threat to the self. Despite this, to date no studies have investigated if SA can mitigate the attention bias toward socially threatening stimuli that is exhibited in individuals high in social anxiety. The aim of the current study is to explore the possible moderating effects of SA manipulation on the attention bias in individuals with high social anxiety. 150 participants completed the study, 8 of which were excluded based upon poor accuracy on the emotional Stroop task. This left a sample of data from 142 participants (aged 18-71 years, M=26.66, SD=l0.94). Participants were required to complete a number of measures online, including the Brief Fear of Negative Evaluation Scale (Leary,1983) and the Beck Depression Inventory- 2nd edition (Beck, Steer & Brown, 1996) as well as undergo a SA manipulation or control condition similar to that used in previous SA studies (Armitage, Harris and Arden, 2011). The independent variables were social anxiety group (high, low) and experimental condition (SA manipulation, control). The dependent variable was emotional interference score as identified by latency times to identify print colour for social threat and control words presented in an emotional Stroop task. A 2 by 2 (Social anxiety: high, low; experimental condition: SA, control; covariate: depression score) ANCOV A was run on the data and revealed no significant main effects for social anxiety group or experimental condition (p>.05). The social anxiety group x experimental condition interaction was also not significant (p>.05). Unfortunately, the aim of the study could not be tested due to no significant differences in emotional interference scores between those high and low in social anxiety. This raises questions about the presence of an attention bias toward socially threatening words by individuals high in social anxiety in an online environment.
Energy transfer in binary collisions of two gyrating charged particles in a magnetic field

description: Binary collisions of the gyrating charged particles in an external magnetic field are considered within a classical second-order perturbation theory, i.e., up to contributions which are quadratic in the binary interaction, starting from the unperturbed helical motion of the particles. The calculations are done with the help of a binary collisions treatment which is valid for any strength of the magnetic field and involves all harmonics of the particles cyclotron motion. The energy transfer is explicitly calculated for a regularized and screened potential which is both of finite range and nonsingular at the origin. The validity of the perturbation treatment is evaluated by comparing with classical trajectory Monte Carlo (CTMC) calculations which also allow to investigate the strong collisions with large energy and velocity transfer at low velocities. For large initial velocities on the other hand, only small velocity transfers occur. There the nonperturbative numerical CTMC results agree excellently with the predictions of the perturbative treatment.

description: We describe a method for constructing genuinely asymmetric (2,0) heterotic strings out of N=2 minimal models in the fermionic sector, whereas the bosonic sector is only partly build out of N=2 minimal models. This is achieved by replacing one minimal model plus the superfluous E_8 factor by a non-supersymmetric CFT with identical modular properties. This CFT generically lifts the weights in the bosonic sector, giving rise to a spectrum with fewer massless states. We identify more than 30 such lifts, and we expect many more to exist. This yields more than 450 different combinations. Remarkably, despite the lifting of all Ramond states, it is still possible to get chiral spectra. Even more surprisingly, these chiral spectra include examples with a certain number of chiral families of SO(10), SU(5) or other subgroups, including just SU(3) x SU(2) x U(1). The number of families and mirror families is typically smaller than in standard Gepner models. Furthermore, in a large number of different cases, spectra with three chiral families can be obtained. Based on a first scan of about 10% of the lifted Gepner models we can construct, we have collected more than 10.000 distinct spectra with three families, including examples without mirror fermions. We present an example where the GUT group is completely broken to the standard model, but the resulting and inevitable fractionally charged particles are confined by an additional gauge group factor.

description: Exclusive electroproduction of pi+ mesons was studied by scattering 27.6 GeV positrons or electrons off a transversely polarized hydrogen target. The single-spin azimuthal asymmetry with respect to target polarization was measured as a function of the Mandelstam variable t, the Bjorken scaling variable x_B, and the virtuality Q^2 of the exchanged photon. The extracted Fourier components of the asymmetry were found to be consistent with zero, except one that was found to be large and that involves interference of contributions from longitudinal and transverse virtual photons.

Teaching the Colourstrings violinist : student development through and beyond Colourstrings
Creators: name: Sanzone, D
Publisher: name: University Of Tasmania
Year: 2023

description: Since the 1970s, Geza Szilvay (born 1943), along with his colleagues at the East-Helsinki Music Institute, have taught several generations of professional violinists using the Colourstrings approach. Colourstrings, however, is generally accepted as an approach for teaching beginners, usually very young children who begin their instrumental studies from approximately age four to seven years old. The aim of this study was to find out how Szilvay and his colleagues develop students through and beyond Colourstrings towards a higher, professional level. Prior to this research, I observed the violin teachers and students at the East-Helsinki Music Institute and am currently undertaking the teacher certification program. My experiences at the teacher training courses and at the Institute were the chief inspiration of this research, which ultimately comprises a review of Colourstrings training and interviews with Szilvay, teachers at the Institute and a certified Colourstrings teacher in Australia. The research findings showed that violin teachers using Colourstrings should consider three areas in their teaching: philosophy, methodology and material. The interviewed teachers were questioned with regards to these three areas and a general pattern was found. The underlying philosophies of Colourstrings are inspired by the Hungarian pedagogue Zolt‚àö¬8n Kod‚àö¬8ly and remain consistent for the teaching of any student no matter what age or level. The methodologies employed by the teachers showed many similarities; however, there were differences found in comparison with the Australian teacher, given environmental contexts. The interviews with the East-Helsinki teachers also provided information on a grade system that has been put into practice at the East-Helsinki Music Institute, which complements the Colourstrings methodology. The participants gave insight into this grade system and how it is employed at the Institute; as a result, a general framework of violin study after Colourstrings was formulated.

description: Many recent papers have questioned Irving and Kirkwood's atomistic expression for stress. In Irving and Kirkwood's approach both interatomic forces and atomic velocities contribute to stress. It is the velocity-dependent part that has been disputed. To help clarify this situation we investigate [1] a fluid in a gravitational field and [2] a steadily rotating solid. For both problems we choose conditions where the two stress contributions, potential and kinetic, are significant. The analytic force-balance solutions of both these problems agree very well with a smooth-particle interpretation of the atomistic Irving-Kirkwood stress tensor.

The effect of two methods of interval training on the physical performance and oxygen recovery curves of rowers
Creators: name: Klavora, Peter
Publisher: name: University of British Columbia
Year: 2011

description: The effectiveness of two training methods was examined. Two equally fast varsity 'four-oar' crews were assigned to two interval.training programs in the late stages of preparation for the competitive season. The three experimental testings measured total work performance completed in six minutes on the rowing ergometer and total oxygen consumption in 15 minutes of recovery. Improvement in the slope and the rate of the fast phase and the slow phase of the oxygen debt curve provided additional criteria in judging the superiority of one method over the other. All rowers were expected to improve their rowing performance as well as their total oxygen debt after an eight week training program. The rowers following training program A were expected to show greater improvement in all testing parameters than the rowers following training program B. A theoretical exponential function of the form A = A₁-K₁ + A₂e-K₂t was fitted to the oxygen data in recovery for all subjects in all three testings. Parameters of the oxygen debt curve, A₁, K₁, A₂, K₂, were calculated and treated statistically. Analysis of variance was used in order to study the effect of training and the effect of the two training methods on the experimental subjects. The results showed a satisfactory fit of the theoretical function to the experimental data of oxygen consumption. The oxygen debt curves after an exhaustive rowing exercise were similar in shape to curves obtained in moderate exercise by other experimenters. The results showed that there was a significant statistical improvement over trials in rowing performance, total oxygen debt, and A₁ parameter of oxygen debt curve for the rowers as a total group. The increase in A₁ was presumably due to the ability of the subjects to maintain a higher oxygen consumption in the terminal stage of work in the last testing. There was no significant difference between the two training programs in any of the test parameters. The results obtained, however, were in the direction expected by the stated hypotheses. The rowers who followed training program A reported slightly higher values for subjective feelings of tiredness immediately after interval rowing session and on the following day. This was as expected.

description: We calculate α^{2}α_{s}^{2} order QED contribution to J/ψproduction in pp(\bar{p})\to J/ψ+c\bar{c} color-singlet process at the Tevatron and LHC in the framework of non-relativistic QCD. The contribution of the interference between the α^{2}α_{s}^{2} QED and α_{s}^{4} QCD is also taken into account. The J/ψproduction associated with a charm quark pair could be a measurable signal at hadron collider experiment. Our calculations show that by including the QED contribution, the p_{t} distribution is enhanced by a factor of 1.5 (1.9) at the Tevatron (LHC) at p_{t}=50 (100) GeV. In addition, the polarization of J/ψturns from unpolarized in all region to increasingly transverse when p_{t} becomes larger.

description: Excerpts from the report: The South is again suffering from low cotton prices. In mid-October prices received by farmers for cotton averaged 26 per cent below the pre-war (1910-1914) average, and cottonseed prices were 6 per cent below the pre-war level. Prices paid by farmers for things they buy at retail have gone down a little, but in comparison with prices farmers receive for cotton their decline is insignificant, and they still average almost 50 per cent higher than in the pre-war period. Undoubtedly much would be gained if farmers would plan their production in light of the fundamental development taking place in supply and demand situations rather than in the light of previously obtained prices. This would stabilize prices and incomes by avoiding periods of overproduction and reducing the effects of business depressions. In addition to the immediate situation there are certain long-time developments which may necessitate adjustments in production over a period of years and it is well to consider those problems before adjustments are forced upon us. The United States is the outstanding producer of cotton and the largest individual consumer, but 56 foreign countries regularly report production of cotton and over half the American crop is consumed in foreign countries. A review of conditions affecting the outlook for cotton, to be adequate, must be world-wide in scope. For the most part these conditions can be grouped as those affecting the quantities of cotton consumers will take at the prices they must pay, or the demand for cotton, and those affecting the availability, or the supply of cotton. Then the question of how the individual farmer can adapt his operations to these general conditions to make the most of his resources and local environment, must be considered. This requires a study of alternative opportunities and cost problems.

description: The official meteorological network is poor on the island of Corsica: only three sites being about 50 km apart are equipped with pyranometers which enable measurements by hourly and daily step. These sites are Ajaccio (41\degree 55'N and 8\degree 48'E, seaside), Bastia (42\degree 33'N, 9\degree 29'E, seaside) and Corte (42\degree 30'N, 9\degree 15'E average altitude of 486 meters). This lack of weather station makes difficult the predictability of PV power grid performance. This work intends to study a methodology which can predict global solar irradiation using data available from another location for daily and hourly horizon. In order to achieve this prediction, we have used Artificial Neural Network which is a popular artificial intelligence technique in the forecasting domain. A simulator has been obtained using data available for the station of Ajaccio that is the only station for which we have a lot of data: 16 years from 1972 to 1987. Then we have tested the efficiency of this simulator in two places with different geographical features: Corte, a mountainous region and Bastia, a coastal region. On daily horizon, the relocation has implied fewer errors than a "naïve" prediction method based on the persistence (RMSE=1468 Vs 1383Wh/m^2 to Bastia and 1325 Vs 1213Wh/m^2 to Corte). On hourly case, the results were still satisfactory, and widely better than persistence (RMSE=138.8 Vs 109.3 Wh/m^2 to Bastia and 135.1 Vs 114.7 Wh/m^2 to Corte). The last experiment was to evaluate the accuracy of our simulator on a PV power grid localized at 10 km from the station of Ajaccio. We got errors very suitable (nRMSE=27.9%, RMSE=99.0 W.h) compared to those obtained with the persistence (nRMSE=42.2%, RMSE=149.7 W.h).

description: It is shown that a linear separation relations are fundamental objects for integration by quadratures of Stäckel separable Liouville integrable systems (the so-called Stäckel systems). These relations are further employed for the classification of Stäckel systems. Moreover, we prove that {\em any} Stäckel separable Liouville integrable system can be lifted to a bi-Hamiltonian system of Gel'fand-Zakharevich type. In conjunction with other known result this implies that the existence of bi-Hamiltonian representation of Liouville integrable systems is a necessary condition for Stäckel separability.

description: During their evolution, Asymptotic Giant Branch (AGB) stars experience a high mass-loss which leads to the formation of a Circumstellar Envelope (CSE) of dust and gas. The mass-loss process is the most important phenomenon during this evolutionary stage. In order to understand it, it is important to study the physical parameters of the CSE. The emission of the CSE in the (sub)millimetre range is dominated by the dust continuum. This means that (sub)millimetre observations are a key tool in tracing the dust and improving our knowledge of the mass-loss process. In this paper we analyse new sub-millimetre observations of 9 evolved stars in order to constrain the CSE physical parameters. The data were taken by the new APEX bolometer LABoCa. The fluxes at 870 um are derived and the extended emission is investigated. We compute the spectral energy distribution (SEDs) using a 1D radiative transfer code, DUSTY which we compared to literature data. Grain properties are calculated using both spherical grains distribution and a Continuous Distribution of Ellipsoids (CDE) and a comparison between the two is drawn. Synthetic surface brightness maps have been derived from the modelling and were compared to the LABoCa brightness maps. We detected the presence of extended emission around four stars. Physical parameters of the circumstellar envelope are derived from SED modelling, such as the dust chemical composition, the dust condensation temperature and the total mass of the envelope. It proves difficult however to fit the SED and the intensity profile simultaneously.

description: The transport and superconducting properties of Ba_{1-x}K_xFe_2As_2 single crystals with T_c = 31 K were studied. Both in-plane and out-of plane resistivity was measured by modified Montgomery method. The in-plane resistivity for all studied samples, obtained in the course of the same synthesis, is almost the same, unlike to the out-of plane resistivity, which differ considerably. We have found that the resistivity anisotropy γ=ρ_c /ρ_{ab} is almost temperature independent and lies in the range 10-30 for different samples. This, probably, indicates on the extrinsic nature of high out-of-plane resistivity, which may appear due to the presence of the flat defects along Fe-As layers in the samples. This statement is supported by comparatively small effective mass anisotropy, obtained from the upper critical field measurements, and from the observation of the so-called "Friedel transition", which indicates on the existence of some disorder in the samples in c-direction.

description: We use soliton methods in order to investigate the interior electrovacuum region of axisymmetric and stationary, electrically charged black holes with arbitrary surrounding matter in Einstein-Maxwell theory. These methods can be applied since the Einstein-Maxwell vacuum equations permit the formulation in terms of the integrability condition of an associated linear matrix problem. We find that there always exists a regular inner Cauchy horizon inside the black hole, provided the angular momentum $J$ and charge $Q$ of the black hole do not vanish simultaneously. Moreover, the soliton methods provide us with an explicit relation for the metric on the inner Cauchy horizon in terms of that on the event horizon. In addition, our analysis reveals the remarkable universal relation $(8πJ)^2+(4πQ^2)^2=A^+ A^-$, where $A^+$ and $A^-$ denote the reas of event and inner Cauchy horizon respectively.

The legal standing of Canadian environmental control organizations
Creators: name: Switzer, James G.
Publisher: name: University of British Columbia
Year: 2011

description: Environmental control has become a major problem in North America's highly industrialized society. Governments are continually striving to find methods to effectively halt and control environmental degradation. One of the major manifestations of the desperate concern for improved environmental quality has been the emergence of a strong "public interest" environmental control movement in the United States. Canada, on the other hand, has given very little scope to public participation in the environmental decision-making process. The object of this paper is to determine the extent to which a strong environmental control movement can contribute to higher environmental quality, and to suggest methods to introduce public participation to the Canadian environmental control system. The advantages and disadvantages of allowing public participation are examined, with the conclusion that a strong environmental control movement with substantial participatory rights is essential to effective and comprehensive environmental control. The conclusion is also reached that the public can most appropriately be represented in the decision process by environmental control organizations. Evaluation is made of the present Canadian laws governing legal standing of "public interest" groups to participate. The lack of such standing is demonstrated both by the rigid standing rules of common law, and the failure of Canadian environmental legislation to relax these rules and adapt them to the specific problems encountered in environmental control law. The American system is considered in detail as an example of relaxed standing with respect to environmental control organizations, and the resultant benefit to environmental control efforts in the jurisdiction. The Americans have enacted the National Environmental Policy Act which requires that every federal agency develop methods of assessing the environmental consequence of propose actions and suggest alternatives to those actions. Failure to comply with these requirements constitutes a reviewable breach. Other American statutes have in effect removed all standing requirements and allow virtually anyone to sue to force compliance with environmental standards and regulations. It is concluded from the American experience that public participation is generally a desirable phenomenon in environmental control. It is further concluded that Canada can no longer justify its exclusion of public representation and requires legislation designed to implement the concept of "public interest" standing. To that end, recommendations are made to adopt an enactment similar to the National Environmental Policy Act in Canada and to introduce a system of registration whereby environmental control organizations, once registered, would be assured of participatory rights at all levels of the Canadian environmental decision-making process.

description: This paper considers the problem of the multiple-input multiple-output (MIMO) Gaussian broadcast channel with two receivers (receivers 1 and 2) and two messages: a common message intended for both receivers and a confidential message intended only for receiver 1 but needing to be kept asymptotically perfectly secure from receiver 2. A matrix characterization of the secrecy capacity region is established via a channel enhancement argument. The enhanced channel is constructed by first splitting receiver 1 into two virtual receivers and then enhancing only the virtual receiver that decodes the confidential message. The secrecy capacity region of the enhanced channel is characterized using an extremal entropy inequality previously established for characterizing the capacity region of a degraded compound MIMO Gaussian broadcast channel.

description: This is an invited presentation with two of my students at #BETT20. The focus of our presentation is about 'Social Media for Academic Studies at Hallam' SMASH which is a ‘students as partners’ project which considers the potential of social media for learning. This student-led special interest group re-looks at the affordances digital and social media tools can provide in and out of the classroom; as a means to organise learning; to support learning and to showcase learning.
The multiple threshold race
Creators: name: Reynolds, AR
Publisher: name: University Of Tasmania

description: The aim of this thesis is to develop a mathematical method to expand simple binary choice models to account for confidence judgements, with an applied focus on recognition memory experiments. More broadly I aim to set out a mathematical method that allows simple evidence accumulator models to explain more complex decisions where responses can be ordered along a single dimension. As an example: binary decisions can be described as a race between two possible responses but they can also be conceptualised as choosing between either end of a continuum of possible responses. This is most stark in noisy perceptual tasks, e.g. a task to detect if the dots are mostly moving left or moving right. This binary judgement could be extended to include responses like \all the dots are moving left\" \"more dots are moving left than right\" or \"as many dots are moving left as right\". Some judgements do not as naturally translate to a continuum of responses but rather the strength or confidence in the decision. This is a particularly important response in tasks with a strong applied setting such as eye-witness identification."

Convergence and coupling for spin glasses and hard spheres

description: We discuss convergence and coupling of Markov chains, and present general relations between the transfer matrices describing these two processes. We then analyze a recently developed local-patch algorithm, which computes rigorous upper bound for the coupling time of a Markov chain for non-trivial statistical-mechanics models. Using the coupling from the past protocol, this allows one to exactly sample the underlying equilibrium distribution. For spin glasses in two and three spatial dimensions, the local-patch algorithm works at lower temperatures than previous exact-sampling methods. We discuss variants of the algorithm which might allow one to reach, in three dimensions, the spin-glass transition temperature. The algorithm can be adapted to hard-sphere models. For two-dimensional hard disks, the algorithm allows us to draw exact samples at higher densities than previously possible.

Stories of pervasive uncertainty : a victim-focused analysis of victim impact statements and sentencing in secual offence cases
Creators: name: Davies, RC
Publisher: name: University Of Tasmania
Year: 2023

description: Victim impact statements outline the harm caused to victims by the offending committed against them. These statements were introduced across Australia from the 1980s as part of legislative and policy reforms that were designed, at least in part, to address barriers contributing to high attrition rates for sexual offence prosecutions, and to reduce anti-therapeutic aspects of victim involvement in the criminal justice process. Yet little research has been undertaken to explore impact statements in the context of sexual offending. Previous research has generally excluded victims of sexual assault, not distinguished their experiences from those of other victims, or not involved interviews with victims themselves. This thesis discusses findings from an empirical study of impact statements and sentencing from the perspective of victims of sexual offending from four Australian jurisdictions. Analyses of sentencing transcripts and interviews with victims and justice professionals reveal four key findings and produce four original contributions to knowledge. The first is the discovery of a lack of understanding among justice professionals, and the victims with whom they work, as to the actual purpose of victim impact statements. Consequently, a model has been developed to achieve clarity and consistency in impact statement purpose and use across the research jurisdictions. The second finding is that the operation of victims' rights instruments in some jurisdictions creates problems around the provision of information to victims. This may be further compounded by the third finding, namely that justice professionals appear to lack training in skills for communicating effectively with victims. In response, recommendations are made for the reform of victims' rights instruments, and strategies are provided to improve communication between professionals and victims of crime. The fourth finding is the identification of different judicial approaches when acknowledging victims and their impact statements at sentencing. This has generated recommendations for educative processes to assist judges to develop a clearer understanding of the possible therapeutic and anti-therapeutic consequences of this acknowledgment.
Electron correlation in metal clusters, quantum dots and quantum rings

description: This short review presents a few case studies of finite electron systems for which strong correlations play a dominant role. In simple metal clusters, the valence electrons determine stability and shape of the clusters. The ionic skeleton of alkali metals is soft, and cluster geometries are often solely determined by electron correlations. In quantum dots and rings, the electrons may be confined by an external electrostatic potential, formed by a gated heterostructure. In the low density limit, the electrons may form so-called Wigner molecules, for which the many-body quantum spectra reveal the classical vibration modes. High rotational states increase the tendency for the electrons to localize. At low angular momenta, the electrons may form a quantum Hall liquid with vortices. In this case, the vortices act as quasi-particles with long-range effective interactions that localize in a vortex molecule, in much analogy to the electron localization at strong rotation.

description: This is a keynote presentation for Galway-Mayo Institute of Technology #DigtalEd Conference. This talk considers the concept of being, belonging and becoming and emphasises the importance of communities and dialogue. I reflect back on my 6Cs model (2013) and how social media has empowered individuals to become digital communicators, collaborators, conversationalists, critics, curators and creators; and the value of educators acting as role models. There are a collection of case studies that demonstrate how we can help students become confident and responsible digital citizens.

Canadian taxation of business and investment income of non-residents
Creators: name: Bonzanigo, Rocco
Publisher: name: University of British Columbia

description: The new Income Tax Act (S.C. 1970-71, c.63), formely known as Bill C-259, has introduced important changes and many new rules into Canadian legislation, which affect taxation of non-residents. This thesis is a study of the tax treatment which the new law imposes on non-residents and an examination of the differences from the previous system. However, taxation of non-residents depends not only on statutes but also on case law. Therefore, attention is devoted to judicial decisions to ascertain whether they conflict with the new statutory provisions. This thesis studies non-residents earning income from a business they carry on in Canada, and deriving income from investments they make in Canada. The comparatively simple situations of persons holding employments in Canada, or receiving pension payments from Canadian sources are not analyzed. The study is limited to the law normally applicable without modifications dependent on international treaties. The thesis is organized in seven main chapters and a short conclusion. The first chapter summarizes the reasons making taxation of non-residents a complexe matter, and the rules governing it. The second chapter is devoted to the definition of residence as well as to a brief comparison with certain other countries. The tax consequences of non-residents carrying on business in Canada and the methods available are examined in the third chapter. The taxation of the different forms of investment income which non-residents may derive from Canada is the object of the fourth chapter. The non-resident-owned investment corporation, that is to say the special vehicle afforded to foreign investors, is analyzed in the fifth chapter. The sixth chapter explains the technical provisions aimed at counteracting thin capitalization. The taxation of capital gains realized by non-residents is studied in the chapter seven. Finally, some conclusions are drawn in the eighth and last chapter.
