description: Representation of under-represented minority (URM) faculty in the health sciences disciplines is persistently low relative to both national and student population demographics. Although some progress has been made through nationally funded pipeline development programs, demographic disparities in the various health sciences disciplines remain. As such the development of innovative interventions to help URM faculty and students overcome barriers to advancement remains a national priority. To date, the majority of pipeline development programs have focused on academic readiness, mentorship, and professional development. However, insights from the social sciences literature related to "extra-academic" (e.g., racism) barriers to URM persistence in higher education suggest the limitations of efforts exclusively focused on cognitively mediated endpoints. The purpose of this article is to synthesize findings from the social sciences literature that can inform the enhancement of URM pipeline development programs. Specifically, we highlight research related to the social, emotional, and contextual correlates of URM success in higher education including reducing social isolation, increasing engagement with research, bolstering persistence, enhancing mentoring models, and creating institutional change. Supporting URM's success in the health sciences has implications for the development of a workforce with the capacity to understand and intervene on the drivers of health inequalities.

description: In Ireland, there are areas where the Irish language is spoken exclusively, these areas are called Gaeltacht. Students living in those areas speak Irish both at home and at school. But outside those areas, schools teach in the English language. This is changing due to Gaelscoileanna. Now students who are speaking English at home and in the neighborhood are being taught in Irish at school. Additive bilingualism occurs in students attending Gaelscoileanna since they are immersed in both languages on a daily basis. This has shown to have positive impacts on mathematics learning. Other countries, such as Wales, Scotland, and Canada, have implemented similar types of schools. Research on Irish-medium language immersion programs effects on mathematics education is presented.

description: The measurement of aerosol growth kinetics at ever smaller sizes toward the transition and free molecular regime is of interest to provide for validation of theoretical predictions. Such measurements remain challenging to accomplish, particularly those occurring in the kinetic regime. Toward this goal, an instrument based on the ultraviolet constant angle Mie scattering (UV-CAMS) method was developed. The instrument utilizes adiabatic expansion to cause supersaturation and drive aerosol growth. Aerosol particles growing by water condensation are illuminated with a pulsed UV laser at 337 nm wavelength and a reference laser with red light (wavelength of 632 nm). The scattered light fluxes at 30° are measured simultaneously and are then compared with size resolved Mie scattering calculations providing aerosol growth measurements. The growth curves obtained from UV match those from the red laser. These measurements allow us to see the first Mie peak for UV scattering for particles in the 500 nm range. This is an almost two-fold resolution increase compared to the smallest particles that can be seen via red laser scattering in similar conditions (first Mie peak above 900 nm).

description: Particle deposition in the human respiratory tract is considered to have negative effects on human health. The lung deposited surface area (LDSA) is an important metric developed to assess the negative health effects of particles deposited in the alveolar region of the human respiratory tract. The measurement of the LDSA is frequently based on the detection of the electrical current carried by diffusion charged particles. Various conversion factors can be used to convert the electric current into LDSA concentration with relatively good accuracy up to the size about 300-600 nm. In this study, we introduce stage-specific LDSA conversion factors for electrical low pressure impactor (ELPI+) data, which enable accurate and real time LDSA concentration and LDSA size distribution measurements in the particle size range from 6 nm to 10 µm. This wide size range covers most of the alveolar deposition of particles, which has not been possible previously by electrical methods. Also, the conversion factors for tracheobronchial and head airways particle surface area deposition were determined, and the stage-specific conversion factors were compared with the single-factor data conversion method. Furthermore, the stage-specific calibration was tested against real-world particle size distributions by simulations and against laboratory-generated aerosols. Particles larger than 300 nm were observed to significantly affect the total LDSA concentration. Stage-specific conversion factors are especially required while measuring aerosols containing larger particles or when considering the surface area deposition in the tracheobronchial region and head airways. The method and the conversion factors introduced in this study can be used to monitor LDSA concentrations reliably in various environments containing particles in different size ranges.

description: The DA white dwarfs in the Sloan Digital Sky Survey, as analyzed in the papers for Data Releases 1 and 4, show an increase in surface gravity towards lower effective temperatures below 11500 K. We study the various possible explanations of this effect, from a real increase of the masses to uncertainties or deficiencies of the atmospheric models. No definite answer is found but the tentative conclusion is that it is most likely the current description of convection in the framework of the mixing-length approximation, which leads to this effect.

description: Amphibians exhibit diverse parental care behaviours, which may be performed by the female, male or both parents. In the Neotropical family Leptodactylidae, frogs in the genus Leptodactylus exhibit different parenting behaviours. The repertoire of care behaviours includes egg/nest attendance, nest chamber sealing, tadpole feeding with trophic eggs, and tadpole attendance associated with complex behaviours, such as pumping behaviour and channel digging. Based on the available information, we found that 23.8% of Leptodactylus species are known to exhibit post-fertilization parental care. Future studies should focus on mechanisms involved in parent-offspring communication, including acoustic and chemical signals. Moreover, behaviours such as provisioning with trophic eggs are not well understood and deserves further investigation. Because of these complex parental care behaviours, tadpole schooling, and relative easy observation, frogs in the genus Leptodactylus represent excellent models for studies interested in parent-offspring communication and evolution of parental care.

description: This paper examines the mathematical and teaching practices of the renowned self-taught Chinese mathematician Hua Loo-keng in the movement of popularizing mathematics in the People’s Republic of China. In this movement, Hua Loo-keng taught industrial workers and peasants with a low level of education how to use fairly advanced mathematical methods in their workplace (agriculture, transportation, or industry). This paper explores the mathematical concepts that Hua Loo-keng taught the workers and farmers and how they applied them in their workplace. An important element in the movement of popularizing mathematics in the People’s Republic of China is the non-traditional methods by which Hua Loo-keng taught the workers and farmers.

description: We review recent studies on spin decoherence of electrons and holes in quasi-two-dimensional quantum dots, as well as electron-spin relaxation in nanowire quantum dots. The spins of confined electrons and holes are considered major candidates for the realization of quantum information storage and processing devices, provided that sufficently long coherence and relaxation times can be achieved. The results presented here indicate that this prerequisite might be realized in both electron and hole quantum dots, taking one large step towards quantum computation with spin qubits.

Exploration of a co-created exposure-based cognitive behavioural physiotherapy approach to the rehabilitation of walking function post-stroke
Creators: name: Kasapi, Alexandra
Publisher: name: University of British Columbia
Year: 2023

description: Purpose: To co-create an exposure-based approach to post-stroke rehabilitation with treating physiotherapists. Additionally, we aimed to explore patient perspectives surrounding the implementation of the novel approach. Methods: Four physiotherapists (PTs) (practicing clinicians) working with stroke patients in a rehabilitation setting (two PTs working in in-patient units, one physiotherapist working in the intensive day rehabilitation program, and one PT working in the out-patient program), alongside clinical researchers in physiotherapy and psychology, were members of the co-creation team. All physiotherapists completed exposure-based cognitive behavioural techniques (EB-CBT) training and provided feedback regarding training components and implementation of the new approach through a series of co-creator meetings, as well as one on one discussions with the lead (clinical physiotherapist/researcher). The two out-patient PTs recruited a total of 6 patients undergoing stroke rehabilitation to participate in the study, and the two in-patient PTs remained as co-creators in this project. At discharge (from rehabilitation) and one-month post discharge, patients participated in semi-structured interviews and responded to Likert statements. Inductive content and thematic analyses were carried out on physiotherapist and patient semi-structured interviews, respectively, to assess perspectives on the integration and implementation of an exposure-based approach to the rehabilitation of walking function post-stroke. Intervention components consisted of education; goal setting; Exposure Hierarchies; homework; and graded exposure informed by the Rate of Perceived Stability (RPS) Scale. Results: We successfully co-created EB-CBT components to the physiotherapy rehabilitation of walking post-stroke in an out-patient setting. In addition, we explored patient perspectives surrounding the integrated approach and found that patients reported positive perspectives surrounding the integrated approach and reported that their PTs were able to help motivate and further challenge/progress patients and one-month after being discharged from their physiotherapy rehabilitation, walking and balance function was improving and patients were able to return to meaningful activities and transition to day-to-day life. Conclusion: Patients perceived the integrated EB-CBT approach to be beneficial to enhancing rehabilitation outcomes and facilitating self-progression. Future research is necessary in order to further modify/refine intervention parameters and to assess potential feasibility, as well as efficacy.

We began observing this star at Keck Observatory as part of the N2K Planet Search Project. Wright et al. (2007) announced the inner two planets to this system, and subsequent observations have revealed the outer planet planet and the proper orbital solution for the middle planet. The planets have minimum masses of 3.9, 1.3, and 0.6 M_Jup and orbital periods of 6.67, 147.7, and 952 d, respectively. We have numerically integrated the family of orbital solutions consistent with the data and find that they are stable for at least 10^6 yr. Our photometric search shows that the inner planet does not transit.

Evidence of Finland’s educational success emerged with the outcome of the first PISA study in 2000. Since then, many have looked to Finland for explanations. Within the field of education, many believe the reasons for the success are primarily pedagogical, referring to Finland’s excellent teachers and high–quality teacher education. Similarly for Singapore, the consistency in the country’s good outcome in the TIMSS study has brought the world’s attention to this small island country. This article explores the similarities and differences in the educational systems of these two countries.

description: Volatility is one of the most important physical properties of organic aerosol (OA), as it determines the partitioning of its components between the vapor and particulate phases. Despite their atmospheric importance, multicomponent OA volatility estimates remain quite uncertain. This study combined thermodenuder (TD) and isothermal dilution measurements to characterize secondary OA (SOA) generated from the ozonolysis of α-pinene and cyclohexene. The SOA from both precursors evaporated similarly in the TD, but behaved quite differently when isothermally diluted by similar amounts. The α-pinene ozonolysis SOA evaporated by only 20% after 2 h of dilution by a factor of around 20, while 65% of the cyclohexene ozonolysis SOA evaporated at the same conditions. The volatility distributions were first estimated by fitting only the evaporation in the TD. This approach resulted in similar volatility distributions for the two systems. Then, the model was used to fit both the evaporation in the TD and the dilution chamber. This technique estimated drastically different volatility distributions with the α-pinene ozonolysis SOA consisting of mostly low-volatility compounds and the cyclohexene ozonolysis SOA consisting of mostly semi-volatile compounds. In the next stage of analysis, the model was updated to account for vapor-phase wall-losses occurring in the dilution chamber. This approach resulted in slightly less volatile SOA and provided some information about the losses of vapors to the walls, but the results were fairly uncertain. These results show the necessity of combining thermal measurements with other techniques to accurately estimate OA volatility. Copyright © 2020 American Association for Aerosol Research
Comparison of the Classroom Practices of Finnish and Icelandic Mathematics Teachers

description: Mathematics teachers in Finland and Iceland are on different tracks. Based on a recent video study, the classroom practices of Finnish mathematics teachers seem to be rather traditional. This is in contrast to the Icelandic teachers many of whom use progressive-minded, learner-based instructional strategies. The classroom practices in Finland include substantial whole-class interaction, while many students in Iceland are getting used to learning independently, without significant collaboration with others. This paper discusses three pedagogical dimensions on which mathematics teaching in Finland and Iceland differ: individualization, learner control, and content-related discourse.

description: In a general metric theory of gravitation in four dimensions, six polarizations of a gravitational wave are allowed: two scalar and two vector modes, in addition to two tensor modes in general relativity. Such additional polarization modes appear due to additional degrees of freedom in modified theories of gravitation or theories with extra dimensions. Thus, observations of gravitational waves can be utilized to constrain the extended models of gravitation. In this paper, we investigate detectability of additional polarization modes of gravitational waves, particularly focusing on a stochastic gravitational-wave background, with laser-interferometric detectors on the Earth. We found that multiple detectors can separate the mixture of polarization modes in detector outputs, and that they have almost the same sensitivity to each polarization mode of stochastic gravitational-wave background.

description: No present observations suggest a technologically advanced extraterrestrial intelligence (ETI) has spread through the galaxy. However, under commonplace assumptions about galactic civilization formation and expansion, this absence of observation is highly unlikely. This improbability is the heart of the Fermi Paradox. The Fermi Paradox leads some to conclude that humans have the only advanced civilization in this galaxy, either because civilization formation is very rare or because intelligent civilizations inevitably destroy themselves. In this paper, we argue that this conclusion is premature by introducing the "Sustainability Solution" to the Fermi Paradox, which questions the Paradox's assumption of faster (e.g. exponential) civilization growth. Drawing on insights from the sustainability of human civilization on Earth, we propose that faster-growth may not be sustainable on the galactic scale. If this is the case, then there may exist ETI that have not expanded throughout the galaxy or have done so but collapsed. These possibilities have implications for both searches for ETI and for human civilization management.

The discussion covers three important aspects of plasma physics: Equilibrium, Stability, and Transport. The section on equilibrium will go through an introduction to ideal magnetohydrodynamics, curvilinear system of coordinates, flux coordinates, extensions to axisymmetric equilibrium, Grad-Shafranov Equation (GSE), Green's function formalism, as well as analytical and numerical solutions to GSE. The section on stability will address topics including Lyapunov Stability in nonlinear systems, energy principle, modal analysis, and simplifications for axisymmetric machines. The final section will consider transport in toroidal systems. We present the flux-surface-averaged system of equations describing classical and non-classical transport phenomena. Applications to the small-sized high-aspect-ratio Damavand tokamak will be described.

description: We model the dynamics of formation of multiple, long-lived, bright solitary waves in the collapse of Bose-Einstein condensates with attractive interactions as studied in the experiment of Cornish et al. [Phys. Rev. Lett. 96 (2006) 170401]. Using both mean-field and quantum field simulation techniques, we find that while a number of separated wave packets form as observed in the experiment, they do not have a repulsive πphase difference that has been previously inferred. We observe that the inclusion of quantum fluctuations causes soliton dynamics to be predominantly repulsive in one dimensional simulations independent of their initial relative phase. However, indicative three-dimensional simulations do not support this conclusion and in fact show that quantum noise has a negative impact on bright solitary wave lifetimes. Finally, we show that condensate oscillations, after the collapse, may serve to deduce three-body recombination rates, and that the remnant atom number may still exceed the critical number for collapse for as long as three seconds independent of the relative phases of the bright solitary waves.

description: The measurement of aerosol growth kinetics at ever smaller sizes towards the transition and free molecular regime is of interest to provide for validation of theoretical predictions. Such measurements remain challenging to accomplish, particularly those occurring in the kinetic regime. Toward this goal, an instrument based on the ultraviolet constant angle Mie scattering (UV-CAMS) method was developed. The instrument utilizes adiabatic expansion to cause supersaturation and drive aerosol growth. Aerosol particles growing by water condensation are illuminated with a pulsed UV laser at 337 nm wavelength and a reference laser with red light (wavelength of 632 nm). The scattered light fluxes at 30° are measured simultaneously and are then compared with size resolved Mie scattering calculations providing aerosol growth measurements. The growth curves obtained from UV match those from the red laser. These measurements allow us to see the first Mie peak for UV scattering for particles in the 500 nm range. This is an almost two-fold resolution increase compared to the smallest particles that can be seen via red laser scattering in similar conditions (first Mie peak above 900 nm).

Tumbo-Insel v. H. Mich. Müller. [1] (Hiezu Taf. IX, Fig. a — e.)
Nasorostrale, frontonasorostrale, erstes und zweites supralabiale jederseits zu einem Schild verschmelzen. — Zwei (hintere) supralabialia; drei frontalia, von denen eines als kleines mit der Spitze nach vorn gerichtetes Dreieck vor den zwei andern liegt. Keine supraocularia. — Analporen sparsam (bei unserm Exemplar 3). Rücken- und Seitenrinnen deutlich; ebenso besteht eine mittlere Bauchrinne, und die zu beiden Seiten von dieser gelegenen Tafelschuppen sind mehr als doppelt so breit als die Rückentafeln. Leibringe 240, Sehwanzringe 20. ln der Mitte des Leibes enthält ein Leibring 24 Tafeln (Segmente), wovon 14 auf die Oberseite (oberhalb der Seitenrinnen), 10 auf die Unterseite kommen. Schwanz 9,6 mal in der Gesammtlänge enthalten (15 mm. zu 145 mm.) Leibesdurchmesser 4 mm.
Im Uebrigen verweise ich bezüglich der Kopfbescbilderung, sowie der Verhältnisse der Aftergegend auf die sehr genauen Zeichnungen. Oberseite des Leibes und Schwanzes, sowie Unterseite des letztern braun, Unterseite des Leibes schmutzig-weiss, Aftergegend milchig-weiss.
Herr G. A. Boulenger hatte die Güte, eine ihm zugesendete Zeichnung mit A. liberiensis zu vergleichen und mir von letzterer eine Skizze zu übersenden. Beide Arten (wie auch A. gracilis Strauch, die mir nur aus der Beschreibung bekannt ist) haben das Gemeinsame des Aufgehens beider ersten Oberlippenschilder; mit letztgenannter Art stimmt A. leonina noch weiters überein in der geringen Anzahl der Afterporen. Im Uebrigen ist aber die Anordnung der Kopfschilder wesentlich verschieden und sie ähnelt am meisten der von A. Mülleri Strauch, bei welcher aber das zweite Oberlippenschild bestehen bleibt, und ausserdem 12 Präanalporen sich ﬁnden.

Historical dynamics of ecosystem services and their social-ecological drivers in British Columbia, Canada
Creators: name: Sutherland, Ira James
Publisher: name: University of British Columbia
Year: 2023

description: Ecosystem services (ES), such as timber, clean water, and nature-based recreation, are co-produced through social and ecological systems that interact at a range of scales. The patterns and drivers of ES are therefore complex, and research is needed to clarify ES dynamics and articulate how land management institutions can adaptively steward ES through an uncertain future. The aim of this dissertation was to analyze how ES have changed over the past century in British Columbia (BC), Canada, and to identify the social-ecological and institutional drivers of these changes. In Chapter 2, I observed through qualitative analysis that persistent institutional structures (e.g., colonial power structures) and functions (e.g., policies) have constrained institutional response to address ecological challenges. Meanwhile, ecological monitoring has acted as a feedback, at times, to foster institutional change and guide more effective landscape management responses. In Chapter 3, I described the data reconstructions I used to monitor the flows and demand of 12 ES across six regions of BC over the past century. In Chapter 4, I used breakpoint analysis to detect abrupt changes in these 12 ES, characterize their overall patterns, and trace possible social-ecological causes. I found that abrupt changes and non-linear trajectories were the norm (77% of ES time series), a finding that challenges prevailing paradigms that view ES as static or monotonically declining. In Chapter 5, I used Granger causality analysis to assess how well annual ES demand (i.e., the amount desired by people) predicts changes in annual ES flows (i.e., the amount of ES produced) and vice-versa. ES demand historically helped predict changes in ES flows, but this relationship has decreased over time or switched direction such that ES flows increasingly drive ES demand, which may reflect rising scarcity in ES supply. Overall, this research has elucidated complex long-term temporal dynamics in ES, tested novel methods for monitoring the social-ecological drivers of ES, and provided strategic recommendations for institutions to maintain ES through time. By leveraging a historical systems approach, I have contributed toward an integrated theory of social-ecological ES dynamics and how land management institutions can navigate complexity to maintain ES.

description: EO AFRICA R&D Facility is a flagship initiative of EO AFRICA with an overarching long-term (> 10 years) goal of supporting an African-European collaboration to enable an active research community and creative innovation processes for a continuous development of Earth Observation (EO) capabilities in Africa. Besides offering a) technical and financial support for 30 research projects to address African EO research challenges related to water scarcity and food security, and b) establishing a digital capacity development platform (Space Academy) to provide domain specific training through face-to-face courses, online courses, webinars, and a massive open online course, the Facility also provides a cloud-based EO data analysis environment (Innovation Lab) to support researchers in accessing and utilizing EO data to produce high-level products and develop innovative EO applications. The Innovation Lab aims to simplify access to data and products (in-situ and EO) and use of open-source algorithms, models, and tools to obtain information relevant to SDGs, as well as to develop original algorithms and applications adapted to African solutions. The presentation provides information on Virtual Research Environments (VREs) of the Lab that allow co-located data and computing services making full use of the Copernicus DIAS infrastructure, explains the technical architecture and key features of the platform, and presents the operation timeline.

description: In this paper, we discuss the available approches of the new governance structures of standardization, in order to propose new hypothesis on the way computer sciences languages are dealt with. We consider the example of the XML language and its applications in order to propose a dynamic analysis of this governance, focusing on the coordination that is done by companies, and the strategic usage they have of these arenas to further their goals. We advocate the development of more of such empirical analysis in order to cover all the perspectives of possible international policies in this area.

LTB spacetimes in terms of Dirac observables

description: The construction of Dirac observables, that is gauge invariant objects, in General Relativity is technically more complicated than in other gauge theories such as the standard model due to its more complicated gauge group which is closely related to the group of spacetime diffeomorphisms. However, the explicit and usually cumbersome expression of Dirac observables in terms of gauge non invariant quantities is irrelevant if their Poisson algebra is sufficiently simple. Precisely that can be achieved by employing the relational formalism and a specific type of matter proposed originally by Brown and Kucha{\v r}, namely pressureless dust fields. Moreover one is able to derive a compact expression for a physical Hamiltonian that drives their physical time evolution. The resulting gauge invariant Hamiltonian system is obtained by Higgs -- ing the dust scalar fields and has an infinite number of conserved charges which force the Goldstone bosons to decouple from the evolution. In previous publications we have shown that explicitly for cosmological perturbations. In this article we analyse the spherically symmetric sector of the theory and it turns out that the solutions are in one--to--one correspondence with the class of Lemaitre--Tolman--Bondi metrics. Therefore the theory is capable of properly describing the whole class of gravitational experiments that rely on the assumption of spherical symmetry.

Publisher: name: Journal of Mathematics Education at Teachers College
Year: 2010

description: Programs like PowerPoint and Keynote have become standard tools for teaching. Despite their ubiquity, an increasing number of educators blame them for both a deskilling of teachers and a dumbing down of students. This article examines some of the concerns that surround slideware-assisted teaching and offers guidelines and heuristics concerned mathematics teachers can use to re-energize and re-intellectualize their use of presentation software products. Special emphasis is placed on slideware’s use in the mathematics classroom.
