description: Stellar bars are a common feature in massive disc galaxies. On a theoretical ground, the response of gas to a bar is generally thought to cause nuclear starbursts and, possibly, AGN activity once the perturbed gas reaches the central super-massive black hole. By means of high resolution numerical simulations we detail the purely dynamical effects that a forming bar exerts on the gas of an isolated disc galaxy. The galaxy is initially unstable to the formation of non-axisymmetric structures, and within 1 Gyr it develops spiral arms that eventually evolve into a central stellar bar on kpc scale. A first major episode of gas inflow occurs during the formation of the spiral arms while at later times, when the stellar bar is establishing, a low density region is carved between the bar co-rotational and inner Lindblad resonance radii. The development of such "dead zone" inhibits further massive gas inflows. Indeed, the gas inflow reaches its maximum during the relatively fast bar formation phase and not, as often assumed, when the bar is fully formed. We conclude that the low efficiency of long-lived, evolved bars in driving gas toward galactic nuclei is the reason why observational studies have failed to establish an indisputable link between bars and AGNs. On the other hand, the high efficiency in driving strong gas inflows of the intrinsically transient process of bar formation suggests that the importance of bars as drivers of AGN activity in disc galaxies has been overlooked so far. We finally prove that our conclusions are robust against different numerical implementations of the hydrodynamics routinely used in galaxy evolution studies.

Subjects: subject: Students, Foreign--Employment

description: This paper examined the experience of international student graduates from Vancouver Island University as they transition into the workforce and on to becoming permanent residents of Canada. Ten international students who had already successfully transitioned to become a permanent resident of Canada or whose permanent residency application was in process were interviewed. Given that they had already navigated the challenges of entering a foreign labour market and had satisfied the requirements under the Canadian Experience Class, participants in the present study were considered highly resilient and able to offer insights into the challenges as well as the facilitating factors or supports that helped them to transition into becoming permanent residents of Canada. International student participants also shared recommendations for other international students who are hopeful in becoming Canadian citizens.

description: The impact of a turbulent flow on wind-driven oceanic near-inertial waves is examined using a linearised shallow-water model of the mixed layer. Modelling the flow as a homogeneous and stationary random process with spatial scales comparable to the wavelengths, we derive a transport (or kinetic) equation governing wave-energy transfers in both physical and spectral spaces. This equation describes the scattering of the waves by the flow which results in a redistribution of energy between waves with the same frequency (or, equivalently, with the same wavenumber) and, for isotropic flows, in the isotropisation of the wave field. The time scales for the scattering and isotropisation are obtained explicitly and found to be of the order of tens of days for typical oceanic parameters. The predictions inferred from the transport equation are confirmed by a series of numerical simulations. Two situations in which near-inertial waves are strongly influenced by flow scattering are investigated through dedicated nonlinear shallow-water simulations. In the first, a wavepacket propagating equatorwards as a result from the $β$-effect is shown to be slowed down and dispersed both zonally and meridionally by scattering. In the second, waves generated by moving cyclones are shown to be strongly disturbed by scattering, leading again to an increased dispersion.

description: Education is facing numerous and complex problems in this constantly evolving world. This research study sought feedback from principals and teachers to discover the most important factors that can promote and improve learning in this new era. The study conducted was a mixed method, online survey involving 8 principals and 29 teachers from public high schools in Mauritius. The survey was designed to collect quantitative and qualitative data from the perspectives, views and experiences of principals and teachers. The findings revealed the most important factors to promote and improve learning as: (a) teacher effectiveness, (b) teacher leadership, (c) personalized learning, (d) motivation, and (e) instructional and transformational leadership. These results aligned with the literature review and confirmed the contribution the findings can make to the Mauritian education system. Based on these findings, suggestions for future research is also included.

description: KMOS (K-Band Multi Object Spectrograph) is a novel integral field spectrograph installed in the VLT's ANTU unit. The instrument offers an ability to observe 24 2.8"$\times$2.8" sub-fields positionable within a 7.2' patrol field, each sub-field producing a spectrum with a 14$\times$14-pixel spatial resolution. The main science drivers for KMOS are the study of galaxies, star formation, and molecular clouds, but its ability to simultaneously measure spectra of multiple stars makes KMOS an interesting instrument for exoplanet atmosphere characterization via transmission spectroscopy. We set to test whether transmission spectroscopy is practical with KMOS, and what are the conditions required to achieve the photometric precision needed, based on observations of a partial transit of WASP-19b, and full transits of GJ 1214b and HD 209458b. Our analysis uses the simultaneously observed comparison stars to reduce the effects from instrumental and atmospheric sources, and Gaussian processes to model the residual systematics. We show that KMOS can, in theory, deliver the photometric precision required for transmission spectroscopy. However, this is shown to require a) pre-imaging to ensure accurate centering and b) a very stable night with optimal observing conditions (seeing $\sim$0.8"). Combining these two factors with the need to observe several transits, each with a sufficient out-of-transit baseline (and with the fact that similar or better precision can be reached with telescopes and instruments with smaller pressure,) we conclude that transmission spectroscopy is not the optimal science case to take advantage of the abilities offered by KMOS and VLT.

Subjects: subject: Education, Secondary
subject: Education, Elementary

description: Transitioning to high school from elementary school can be a challenging process for students. As students have become accustomed to a specific building, group of teachers and sets of routines and procedures, the new changes can be hard on a young person who is already experiencing vast changes physically, emotionally and socially. Students need to feel confident that they have within themselves the skills necessary to be successful. They also need to feel that the new adults they will be surrounded with are there to support and guide them to be successful. While there is much research regarding elementary to high school transition, the absence of student voice emerged throughout the available data. The current researcher wanted to discover student experiences with transitioning from their elementary school to the high school, what is currently being offered by schools to support a positive transition, and what more could be done from the point of view of students. The aim of this research was to gather information regarding school transition from the perspective of the students who are experiencing the transition first hand. Using a mixed-methods approach, including both quantitative and qualitative research methods, 19 surveys and 3 student interviews provided the data. Through the survey, Likert responses were calculated and organized into tables and analyzed. Open-ended questions were also organized in tables and analyzed. Interviews were transcribed and coded for themes and patterns. The results of the data indicated that students do feel a sense of belonging in their new school environment and enjoy the choice and freedom that high school brings. Additionally, while students express some nervousness over school transition, the overall feeling is one of excitement for the new opportunities and people that are introduced to them.

Subjects: subject: Education--China

description: Education plays a large part in the future advancement of the world’s societies, economies, and life satisfaction. The purpose of this research process is to examine several aspects of early childhood education, which is a foundational building block of education in general, and then specifically to focus on weaknesses in the Chinese educational system. I begin by comparing educational features, mostly applied in Western countries, to what is practiced today in China. China currently relies on traditional forms of education and could gain by changing some educational methods. The framework of this project is divided into five parts. China is affected by many contemporary problems, which I discuss in detail in the first part. Then, I review changes China has applied in the past and adjustments it could make in the future to better its system. I provide a sample of the resources I reference and a timeline for my research project. There are key differences between early childhood education in China and Western countries, which include aspects of teaching methods, educational resources, and cultural norms. Based on my research, I developed several conclusions regarding issues China faces and potential solutions. Changes to education requires collaboration between government, education institutions, and parents. Moreover, China needs to pay more attention to improving the educational resources it provides. For instance, reducing teacher turnover would improve both educational quality and early child development. There is a long road ahead of us, so we must continually learn, adjust, and apply new educational methods to our own cultural contexts.

description: In \emph{bandwidth allocation games} (BAGs), the strategy of a player consists of various demands on different resources. The player's utility is at most the sum of these demands, provided they are fully satisfied. Every resource has a limited capacity and if it is exceeded by the total demand, it has to be split between the players. Since these games generally do not have pure Nash equilibria, we consider approximate pure Nash equilibria, in which no player can improve her utility by more than some fixed factor $α$ through unilateral strategy changes. There is a threshold $α_δ$ (where $δ$ is a parameter that limits the demand of each player on a specific resource) such that $α$-approximate pure Nash equilibria always exist for $α\geq α_δ$, but not for $α< α_δ$. We give both upper and lower bounds on this threshold $α_δ$ and show that the corresponding decision problem is ${\sf NP}$-hard. We also show that the $α$-approximate price of anarchy for BAGs is $α+1$. For a restricted version of the game, where demands of players only differ slightly from each other (e.g. symmetric games), we show that approximate Nash equilibria can be reached (and thus also be computed) in polynomial time using the best-response dynamic. Finally, we show that a broader class of utility-maximization games (which includes BAGs) converges quickly towards states whose social welfare is close to the optimum.

description: Suzaku observations of the Wolf-Rayet binary WR 140 (WC7pd+O5.5fc) were made at four different times around periastron passage in 2009 January. The spectra changed in shape and flux with the phase. As periastron approached, the column density of the low-energy absorption increased, which indicates that the emission from the wind-wind collision plasma was absorbed by the dense W-R wind. The spectra can be mostly fitted with two different components: a warm component with kT=0.3--0.6 keV and a dominant hot component with kT~3 keV. The emission measure of the dominant, hot component is not inversely proportional to the distance between the two stars. This can be explained by the O star wind colliding before it has reached its terminal velocity, leading to a reduction in its wind momentum flux. At phases closer to periastron, we discovered a cool plasma component in a recombining phase, which is less absorbed. This component may be a relic of the wind-wind collision plasma, which was cooled down by radiation, and may represent a transitional stage in dust formation.

Circle time check-ins in secondary schools: a classroom approach to improving students’ social responsibility
Creators: name: Zimmer, Carmen M.E.
Publisher: name: Vancouver Island University - Royal Roads University
Year: 2018
Subjects: subject: Social skills in adolescence

description: The purpose of this study was to add to the field of research on circle time use in secondary schools and on the use of Circle Time Check-Ins in secondary schools for creating a sense of belonging and improving students’ social and emotional skills. The author hoped her research would also provide motivation for other educators to explore how circle process can benefit students of all ages, abilities, and cultural backgrounds. The author’s personal interest in creating a more welcoming environment for students in secondary school and to promote positive interactions between students was a motivating factor in the creation of this study. Additionally, finding research that supported the circle as a successful method for teaching and developing social and emotional skills in elementary students and for build belonging in college and university students, and further research which demonstrated the positive relationship between peer acceptance, friendships, and future academic achievement were other factors that strengthened the author’s interest in examining Circle Time Check-Ins. This quantitative study investigated the degree to which a class of Grade 8 students’ reported social responsibility levels improved after participating in weekly Circle Time Check-Ins. Student participants completed a survey to measure their levels on the construct of ‘social responsibility’ before and after the 8-session treatment period. Results indicated that although some students’ scores improved, the treatment did not result in a meaningful improvement for the majority of students. Factors that may have had an effect on the results of this study such as the frequency and content of the discussions, facilitator confidence, and other external factors that could have influenced the students’ responses are discussed. Limitations to this study including its purely quantitative nature are addressed, and suggestions for future researchers and secondary educators are presented.

Pretreatment of milled and unchopped sugarcane bagasse with vortex based hydrodynamic cavitation for enhanced biogas production

Year: 2023
Subjects: subject: Chemical sciences

description: Anaerobic digestion can potentially valorise sugarcane bagasse to biogas and fertiliser. Pretreatment is however required to overcome recalcitrance and enhance the biogas yields. Literature reporting the investigation of various biomass pretreatments often use milled biomass as substrate rather than as-received fibrous biomass. This does not establish the true influence of the pretreatment type on biogas generation. Additionally, milling energy is also ignored when calculating net energy gains from enhanced biogas yields and are thus misleading. In this work, a vortex-based hydrodynamic cavitation device was used to enhance the biomethane yields from fibrous as-received biomass for the first time. Clear justification on why milled biomass must not be used as substrates for demonstrating the effect of pretreatment on biogas production is also discussed. The net energy gain from milled hydrodynamic cavitation pre-treated bagasse can be similar to as-received bagasse only when the specific milling energy is ≤700 kWh/ton.

description: The iron K$α$ line commonly observed in the X-ray spectrum of black hole candidates is produced by X-ray fluorescence of the inner accretion disk. This line can potentially be quite a powerful tool to probe the spacetime geometry around these objects and test the Kerr black hole hypothesis. In a previous paper, we studied the ability to constrain possible deviations from the Kerr solution from the standard time-integrated iron line spectrum within the Cardoso-Pani-Rico framework. In the present work, we expand on that study and consider iron line reverberation mapping in the CPR framework. That is, we consider the time-evolution of the iron line profile in response to fluctuations in the X-ray primary source. Our simulations clearly show that the time information in reverberation mapping can better constrain the background metric than the time-integrated approach, and this is true, notably, for the deformation parameter $ε^r_3$, which is only weakly informed by a time-integrated observation.

description: Results from item-method directed forgetting suggest that individuals are able to intentionally forget processed information. Most research suggests that either selective rehearsal of to-be-remembered or inhibitory control of to-be-forgotten information is accountable for the effects of intentional forgetting. Some research, however, hypothesized that the time to process information mediates the underlying mechanism. To test this hypothesis, the current study investigated associations between oscillatory power in theta (3–7.5 Hz) and alpha frequencies (8–13 Hz) and intentional forgetting in human participants and explored whether or not these mechanisms depended on processing time. Previously, theta power was shown to be associated with the creation of episodic memory traces and alpha power with inhibition. We therefore expected to find associations between these neural signatures and behavioral effects. Consistent with our hypotheses, we revealed increased theta power for to-be-remembered and increased alpha power for to-be-forgotten information and that the effects of activity in both frequency bands were influenced by the time individuals were given for processing the memory cue. These results suggest that not one but two mechanisms, rehearsal and inhibitory control, are accountable for item-method directed forgetting, both with different temporal profiles.

description: We present the first measurement of a local fast-ion 2D velocity distribution function $f(v_\parallel, v_\perp)$. To this end, we heated a plasma in ASDEX Upgrade by neutral beam injection and measured spectra of fast-ion D-alpha (FIDA) light from the plasma center in three views simultaneously. The measured spectra agree very well with synthetic spectra calculated from a TRANSP/NUBEAM simulation. Based on the measured FIDA spectra alone, we infer $f(v_\parallel, v_\perp)$ by tomographic inversion. Salient features of our measurement of $f(v_\parallel, v_\perp)$ agree reasonably well with the simulation: the measured as well as the simulated $f(v_\parallel, v_\perp)$ are lopsided towards negative velocities parallel to the magnetic field, and they have similar shapes. Further, the peaks in the simulation of $f(v_\parallel, v_\perp)$ at full and half injection energies of the neutral beam also appear in the measurement at similar velocity-space locations. We expect that we can measure spectra in up to seven views simultaneously in the next ASDEX Upgrade campaign which would further improve measurements of $f(v_\parallel, v_\perp)$ by tomographic inversion.

description: In this paper, the shape evolution of an aluminium flyer is characterized by a 16-probe Photonic Doppler Velocimeter while being impulsed by a Vaporizing Foil Actuator. For high-speed manufacturing, understanding the shape evolution of a flyer can advance the understanding of the characteristics of the applied pressure as well as the dynamics of the material; however, shock-driven process conditions often make it difficult to perform an in-situ study due to its rapidity and high non-equilibrium nature. Characterization of flyer evolution is also essential for comprehending the mechanism of impact welding, as it can enable measuring the process parameters at the time of collision, thus allowing for the prediction of the weld interface structure. An example is provided with an Al-Mg weld interface, showing the process-microstructure relationship of an impact welding process.

description: Density functional theory provides the most widespread framework for the realistic description of the electronic structure of solids, but the description of strongly-correlated systems has remained so far elusive. Here we consider a particular limit of electrons in a periodic ionic potential in which a one-band description becomes exact all the way from the weakly-correlated metallic regime to the strongly-correlated Mott-Hubbard regime. We provide a necessary condition a density functional should fulfill to describe Mott-Hubbard behavior and show that it is not satisfied by standard and widely used local, semilocal and hybrid functionals. We illustrate the condition in the case of a few-atom system and provide an analytic approximation to the exact exchange-correlation potential based on a variational wave function which shows explicitly the correct behavior providing a robust scheme to combine lattice and continuum methods.

Post-Data-Collection Pre-Registration of the Data-Analysis-Protocol for the AMP-TPP-3 study (A counter-factual replication study to check for potential false positive results produced by the experimental set-up employed in the AMP-TPP-1 and AMP-TPP-2 studies)

description: The AMP-TPP-3 study is a counter-factual replication study to check for potential false positive results produced by the experimental set-up employed in the AMP-TPP-1 and AMP-TPP-2 studies (AMP-TPP-1 = a study using the Advanced Meta-experimental Protocol (AMP) to test precognitive effects claimed by Bem in an online replication of the Transparent Psi Project (TPP) AMP-TPP-2 = a partial direct replication of the AMP-TPP-1 study) The goal of the AMP-TPP-3 study was and is to reproduce – as closely as possible – the scientific processes that were implemented during the AMP-TPP-1 and AMP-TPP-2 studies – but in the absence of any test subjects (=participants). This represents an advanced control test strategy known as counterfactual meta-experimentation (CFME) in the AMP (Walleczek and von Stillfried, 2019) which constitutes a check for experimental errors. Data collection has been completed at the time of this pre-registration, but the data has not been looked at. The purpose of this pre-registration is to specify in advance and in detail the exact analyis to be carried out on the collected data.

description: In this paper we study the critical behavior of an $N$-component $ϕ^{4}$-model in hyperbolic space, which serves as a model of uniform frustration. We find that this model exhibits a second-order phase transition with an unusual magnetization texture that results from the lack of global parallelism in hyperbolic space. Angular defects occur on length scales comparable to the radius of curvature. This phase transition is governed by a new strong curvature fixed point that obeys scaling below the upper critical dimension $d_{uc}=4$. The exponents of this fixed point are given by the leading order terms of the $1/N$ expansion. In distinction to flat space no order $1/N$ corrections occur. We conclude that the description of many-particle systems in hyperbolic space is a promising avenue to investigate uniform frustration and non-trivial critical behavior within one theoretical approach.

Law of the Tendency of the Rate of Profit to Fall

description: The thesis focuses on the apparent mismatch between the recurring character of capitalist crises and the particularistic explanations proposed by academia, with a particular emphasis on Greece. Its research aim is to examine whether the contemporary Greek crisis was an unavoidable occurrence or the contingent outcome of poor regulation, policy making and planning. By deploying materialist dialectics and scientific abstraction, the thesis explores the concept of the unavoidability of crises and empirically tests the selected theoretical framework in the ailing Greek economy. From a theoretical standpoint, the thesis manages to turn the possibility of crises into actuality (reality), thus establishing their necessary character, by tracing the subsequent metamorphoses of the contradiction inherent to the commodity form in economic relations of higher order. Starting from the commodity form, which is the cell-form of capitalist production, the analysis gradually ascends to economic forms of growing complexity until it traces the contradiction between use-value and value at the level of enlarged capital reproduction, which is capitalism’s actual (real) modus operandi. From an empirical standpoint, the thesis tests Marx’s controversial Law of the Tendency of the Rate of Profit to Fall in both sides of capitalism’s cyclicity, namely growth (accumulation) and recovery. The results of the analysis corroborate the modern relevance of the law, pointing towards a deep structural crisis of overaccumulation characterised by very low profit rates. The main contribution of the thesis is that it interconnects all competing Marxist-informed theories of crises into a single, coherent framework which treats all potential causes of crises as manifestations of the antithesis inherent in the commodity form directly stemming from capitalism’s exploitative property relations. The thesis also develops a novel approach for the empirical evaluation of LTRPF that surpasses the measurement limitations peculiar to the traditional method and it also sheds light on the operation of the law at the under-researched phase of capitalist recovery.

description: Interfacial interactions allow the electronic properties of graphene to be modified, as recently demonstrated by the appearance of satellite Dirac cones in the band structure of graphene on hexagonal boron nitride (hBN) substrates. Ongoing research strives to explore interfacial interactions in a broader class of materials in order to engineer targeted electronic properties. Here we show that at an interface with a tungsten disulfide (WS2) substrate, the strength of the spin-orbit interaction (SOI) in graphene is very strongly enhanced. The induced SOI leads to a pronounced low-temperature weak anti-localization (WAL) effect, from which we determine the spin-relaxation time. We find that spin-relaxation time in graphene is two-to-three orders of magnitude smaller on WS2 than on SiO2 or hBN, and that it is comparable to the intervalley scattering time. To interpret our findings we have performed first-principle electronic structure calculations, which both confirm that carriers in graphene-on-WS2 experience a strong SOI and allow us to extract a spin-dependent low-energy effective Hamiltonian. Our analysis further shows that the use of WS2 substrates opens a possible new route to access topological states of matter in graphene-based systems.

description: Surgical procedures are accompanied by various complications such as decreased respiratory muscle strength, functional capacity, quality of life, and an increase in the length of hospital stay. A growing body of evidence indicates that exercise-based prehabilitation offered before major abdominal surgeries can improve the above-mentioned complications. Considering the socioeconomic inequalities, educational characteristics, and healthcare system, which are different in Low and Lower Middle-Income Countries, it is important to know whether interventions such as prehabilitation are feasible and effective in patients undergoing elective abdominal surgeries. Hence, we set out to determine the role of exercise-based prehabilitation in patients opting for these surgeries.
