description: In this paper we discuss some general aspects of the gravitational wave background arising from post-inflationary short-lasting cosmological events such as phase transitions. We concentrate on the physics which determines the shape and the peak frequency of the gravitational wave spectrum. We then apply our general findings to the case of bubble collisions during a first order phase transition and compare different results in the recent literature.

An investigation of university students' views about teaching and learning English through their own experiences in high schools and university of mainland China
Creators: name: Lu, J
Publisher: name: University Of Tasmania
Year: 2023

description: English has become one of the most important subjects after the restoration of the College Entrance Examination in 1978 in mainland China. With the development of the Chinese economy and technology, Chinese students and graduates are provided with more opportunities to study and work collaboratively with the world community. Consequently, their English proficiency is closely related to their study and career plans. Therefore, it is important to investigate how students perceive their English learning and their teachers' teaching as this could both benefit students and teachers in an emerging discourse of English education. The aim of this study was to investigate university students' perceptions about their teachers' teaching and their learning English through their own experiences in high schools and a university in mainland China. The investigation focused on the following key areas: the participants' perceptions of their English learning and teachers' teaching in high schools; the perceptions of their English learning and their teachers' teaching in the university; a comparative examination of these two learning discourses from the views of the students; and the participants' preferred learning and teaching models in the Chinese context. This study employed both quantitative and qualitative research approaches for data collection and analysis. It included two phases: the questionnaire and semi- structured interviews. The statistical data were analyzed using the SPSS (Statistical Package for the Social Science) software version 21. The textual data collected from the semi-structured interviews were analyzed using the NVivo software version 10. Thematic analysis was used in the qualitative data analysis. The results of this study indicated that huge differences of English teaching models utilized between high schools and universities existed in mainland China. This huge gap could create problems for Chinese students' learning transition and individual learning. The findings suggested that the current English assessments for both high schools students and university students should be improved, particularly, the English test in the College Entrance Examination. Meanwhile, transitional guidance was strongly suggested by university students, particularly, to take a shift from a perception of traditional classrooms in high schools to a 'student-centered' classroom in the university. Based on the findings, policy implications, implications for practice and directions for further research were also addressed.

description: We investigated the effects of annealing on LaMnO$_3$ epitaxial thin films grown by pulsed laser deposition and propose an efficient method of characterizing their stoichiometry. Structural, magnetic, and optical properties coherently indicate non-stoichiometric ferromagnetic and semiconducting phases for as-grown LaMnO$_3$ films. By annealing in an oxygen-reducing atmosphere, we recovered the antiferromagnetic and insulating phases of bulk-like stoichiometric LaMnO$_3$. We show that non-destructive optical spectroscopy at room temperature is one of the most convenient tools for identifying the phases of LaMnO$_3$ films. Our results serve as a prerequisite in studying LaMnO$_3$ based heterostructures grown by pulsed laser deposition.

description: We study the interaction between polarized terahertz (THz) radiation and micro-structured large-area graphene in transmission geometry. In order to efficiently couple the radiation into the two-dimensional material, a lateral periodic patterning of a closed graphene sheet by intercalation doping into stripes is chosen. We observe unequal transmittance of the radiation polarized parallel and perpendicular to the stripes. The relative contrast, partly enhanced by Fabry–Perot oscillations reaches 20%. The effect even increases up to 50% when removing graphene stripes in analogy to a wire grid polarizer. The polarization dependence is analyzed in a large frequency range from <80 GHz to 3 THz, including the plasmon–polariton resonance. The results are in excellent agreement with theoretical calculations based on the electronic energy spectrum of graphene and the electrodynamics of the patterned structure.
Intertwined: An investigation into becoming an artist and teacher
Creators: name: MacDonald, AJ
Publisher: name: University Of Tasmania
Year: 2023

description: This study investigates becoming an artist and teacher and, in doing so, explores the ways that artist and teaching practices interact and the implications this interaction can have upon beginning teachers' transition into professional practice. The impetus for this study derives from an identified need for research to deliver further insight into the challenges inherent to becoming an artist and teacher (Graham & Zwirn, 2010; Hall, 2010). A hybridised methodology is adopted, where methods integral to autoethnography, narrative inquiry and a/r/tography are drawn together to generate a series of intricately layered insights into becoming an artist and a teacher. The study explores becoming an artist and teacher from three distinct participant perspectives: early career (myself), and established and master artist and teacher (two other participants). Within this hybridised framework, I interweave the creative and analytic, where our perspectives of experience acknowledge how \the self does not exist in isolation‚ÄövÑvp (Griffin1999 p. 51) and we can explore becoming through the shaping and sharing of our stories. Subsequently this study encourages powerful connection making where the creative qualities of the study help activate and increase reader transferability (Huberman 1989; Webster & Mertova 2007). The reader is introduced to an eclectic collection of literature pertinent to what is already known about becoming an artist and teacher. It is here that the analytical lenses through which the reader is encouraged to examine the ways artists and teachers attend to the negotiation of relationships inherent to their practices are extrapolated. In examining the literature around artists teachers and the formation of professional identity and practice I surface what is already known in regard to how and why artists become teachers and how pre-service art teachers are prepared for the challenges of professional practice and negotiating balance between artist and teacher selves. In offering an existing picture of what is already known about becoming an artist and a teacher the reader can orient themselves with the issues identified as being at the heart of the research reported in this thesis."

description: Natural language interfaces are becoming more and more common but are extremely difficult to build, to maintain, and to port to new domains. NLCI, the Natural Language Command Interpreter, is an architecture for building and porting such interfaces quickly. NLCI accepts commands as plain English texts and translates the input sentences into sequences of API calls that implement the intended actions. At its core is an ontology that models the API. In this demonstration we show how a developer can provide a natural language interface for his or her API by preparing an API ontology. We also show how NLCI analyzes the input text. As an example we use an API that steers a Lego EV3 robot. A short video illustrating the process is available at http://dx.doi.org/10.5445/DIVA/2019-692.
Anisotype heterojunctions involving wide band gap II-VI semiconductors
Creators: name: Taneja, Narayan Dass
Publisher: name: University of British Columbia
Year: 2011

description: This thesis is concerned with (i) the theory of anisotype hetero-junctions and (ii) the fabrication and study of heterojunctions of wide band, gap II-VI compounds with other semiconductors. The theory of anisotype heterojunctions without interface states is discussed on the basis of minority carrier injection. Expressions for the built-in voltage and current voltage relations are derived. The recombination- generation of the carriers in heterojunctions with interface states is considered, using Sah-Shockley-Noyce. theory. The expressions for the recombination-generation rate of the carriers for nine different cases are derived considering three carrier transport mechanisms. ZnSe films were deposited on Ge, GaAs and mica by sublimation under near-equilibrium conditions in an ultra high vacuum. The crystallite size in the films deposited on mica at 500°c was about 15μ. Epitaxy of ZnSe on GaAs was observed around 380°C. The conductivity and Hall mobility of the films on mica were measured under illumination and the results are explained on the basis of a mosaic film model. The photoconductivity of the films was barrier limited at low intensities but carrier limited at high intensities. The nInAs-pZnTe heterojunctions were fabricated by the interface alloying technique. The current voltage and capacitance-voltage characteristics of the devices were studied, and their theoretical relations are derived. Light emission was observed in these heterojunctions under reverse bias conditions. The spectrum of the emitted light was in the energy range of 1.69 eV to 3.5 eV. A number, of peaks were observed in the spectrum at low currents while at high currents only one peak at 2.04 eV was observed. An energy band diagram of ZnTe with different impurity centers is developed to explain the electroluminescence characteristics. The pGe-CdS (photosensitive) heterojunctions were made by a simple alloying technique. The current-voltage and capacitance-voltage characteristics of the heterojunctions were studied under different illumination intensities. The I-V characteristics were non-rectifying at low intensities but rectifying at high intensities. Energy band diagrams, equivalent circuits and the theory of the prepared devices are discussed.

description: Tensor rank refers to the number of product states needed to express a given multipartite quantum state. Its non-additivity as an entanglement measure has recently been observed. In this note, we estimate the tensor rank of multiple copies of the tripartite state $\ket{W}=\tfrac{1}{\sqrt{3}}(\ket{100}+\ket{010}+\ket{001})$. Both an upper bound and a lower bound of this rank are derived. In particular, it is proven that the tensor rank of $\ket{W}^{\otimes 2}$ is seven, thus resolving a previously open problem. Some implications of this result are discussed in terms of transformation rates between $\ket{W}^{\otimes n}$ and multiple copies of the state $\ket{GHZ}=\tfrac{1}{\sqrt{2}}(\ket{000}+\ket{111})$.

description: It is shown that the previously noted extreme perturbative instability of the longitudinal structure function F_L(x,Q^2) in the small Bjorken-$x$ region, is a mere artefact of the commonly utilized `standard' gluon distributions. In particular it is demonstrated that using the appropriate -- dynamically generated -- parton distributions at NLO and NNLO, F_L(x,Q^2) turns out to be perturbatively rather stable already for Q^2 $\geq$ O(2-3 GeV^2).

description: Dark energy in General Relativity is typically non-interacting with other matter. However, it is possible that the dark energy interacts with the dark matter, and in this case, the dark matter can violate the universality of free fall (the weak equivalence principle). We show that some forms of the dark sector interaction do not violate weak equivalence. For those interactions that do violate weak equivalence, there are no available laboratory experiments to probe this violation for dark matter. But cosmology provides a test for violations of the equivalence principle between dark matter and baryons -- via a test for consistency of the observed galaxy velocities with the Euler equation.

description: The objective of this study was to assess the effectiveness of the Interprofessional Care Transitions Clinic (ICTC) in reducing preventable readmissions and their associated costs among Medicare/Medicaid patients. A prospective cohort study was conducted among adults who were discharged from the University of Maryland Prince George’s Hospital Center to assess the comparative effectiveness of a clinic-based intervention in terms of readmission events, potentially avoidable utilization, length of stay, and hospital charges. Outcomes were evaluated at 1 month, 3 months, and 6 months post-discharge. There were statistically significant differences in the following outcomes (follow-up period): proportion of readmissions (3 months), potentially avoidable utilization (1 month), and mean medical charges for ICTC patients compared to non-ICTC patients (1 month). This program was aimed at testing the impact of having an interprofessional team focused on providing holistic patient-centered care.
A Timeon Model of Quark and Lepton Mass Matrices

Year: 2009

description: It is proposed that $T$ violation in physics, as well as the masses of electron and $u, d$ quarks, arise from a pseudoscalar interaction with a new spin 0 field $τ(x)$, odd in $P$ and $T$, but even in $C$. This interaction contains a factor $iγ_5$ in the quark and lepton Dirac algebra, so that the full Hamiltonian is $P$, $T$ conserving; but by spontaneous symmetry breaking, the new field $τ(x)$ has a nonzero expectation value $\neq 0$ that breaks $P$ and $T$ symmetry. Oscillations of $τ(x)$ about its expectation value produce a new particle, the "timeon". The mass of timeon is expected to be high because of its flavor-changing properties. The main body of the paper is on the low energy phenomenology of the timeon model. As we shall show, for the quark system the model gives a compact 3-dimensional geometric picture consisting of two elliptic plates and one needle, which embodies the ten observables: six quark masses, three Eulerian angles $θ_{12}, θ_{23}, θ_{31}$ and the Jarlskog invariant of the CKM matrix. For leptons, we assume that the neutrinos do not have a direct timeon interaction; therefore, the lowest neutrino mass is zero. The timeon interaction with charged leptons yields the observed nonzero electron mass, analogous to the up and down quark masses. Furthermore, the timeon model for leptons contains two fewer theoretical parameters than observables. Thus, there are two testable relations between the three angles $θ_{12}, θ_{23}, θ_{31}$ and the Jarlskog invariant of the neutrino mapping matrix.

A study of the effect of a specially designed program upon the expressed musical preferences of a selected grade three class for contemporary music
Creators: name: Colby, James F.
Publisher: name: University of British Columbia
Year: 2011

description: This study was undertaken to determine whether or not young childrens’ preferences for contemporary art music, through participation in a classroom music program emphasizing creativity, can be altered. The students participating in this experiment were the grade three class at Vancouver College, a private boys school in Vancouver, B.C., where the researcher was employed as music instructor for the 1969-70 school term. A music preference inventory was given to the students prior to initiating the classroom program. The inventory consisted of the following eight selections chosen by the researcher as representative of various twentieth century compositional styles: "Ionisation" - Edgar Varèse; "Akrata" - Iannis Xenakis; "Gesang der Jünglinge" - Karlheinz Stockhausen; "Visage" - Luciano Berio; "Le Marteau sans Maȋtre" - Pierre Boulez; "Piece for Four Pianos" - Morton Feldman; "Five Pieces for Orchestra, Op.16" - Arnold Schoenberg; and, "Cantata No. 1, Op.29" - Anton Webern. Students marked their preference on a graphic rating scale of five divisions. The researcher later superimposed a twelve-point scale over the test-scale, in interpreting the scores. Following this pre-test, the students participated in a twelve-week classroom music program which stressed rhythmic improvisation, composition in twelve-tone technique, percussion pieces, exploration of sound sources, etc. The program was designed by the researcher based on work by Carl Orff, Zoltan Kodaly, R. Murray Schafer, Peter Maxwell Davies, Richard Addison and George Self. At the end of the program the same preference inventory was again administered to the students as a post-test. Final scores were interpreted by means of a two-tail test. Only one selection showed a change in preference (in this case, an increase) at a statistically significant level of five per cent. Stockhausen's "Gesang der Jünglinge" attained a critical ratio of 5.34. Certain limitations were recognized: 1) the small sampling of students (twenty-two); 2) the relatively short duration of the experimental part of the study (twelve weeks), and 3) the lack of any control group. The researcher therefore concluded that, within the severe limitations of this study, his hypothesis was invalid: that participation in a classroom music program stressing creativity will alter a grade three student's preference for contemporary art music.

description: We present three dimensional smoothed particle hydrodynamics (SPH) calculations of irradiation-driven warping of accretion discs. Initially unwarped planar discs are unstable to the radiation reaction when the disc is illuminated by a central radiation source. The disc warps and tilts and precesses slowly in a retrograde direction; its shape continuously flexes in response to the changing orientation of the Roche potential. We simulate ten systems: eight X-ray binaries, one cataclysmic variable (CV), and a `generic' low mass X-ray binary (LMXB). We adopt system parameters from observations and tune a single parameter: our model X-ray luminosity ($L_{*}$) to reproduce the observed or inferred super-orbital periods. Without exception, across a wide range of parameter space, we find an astonishingly good match between the observed $L_{X}$ and the model $L_{*}$. We conclude irradiation-driven warping is the mechanism underlying the long periods in X-ray binaries. Our Her X-1 simulation simultaneously reproduces the observed $L_{X}$, the "main-" and "short-high" X-ray states and the orbital inclination. Our simulations of SS 433 give a maximum warp angle of $18.6^{\circ}$, a good match to the cone traced by the jets, but this angle is reached only in the outer disc. In all cases, the overall disc tilt is less than $\degrees{13}$ and the maximum disc warp is less than and or equal to $\degrees{21}$.

description: The role of thermal fluctuations on the conformational dynamics of a single closed filament is studied. It is shown that, due to the interaction between charges and bending degrees of freedom, initially circular aggregates may undergo transformation to polygonal shape. The transition occurs both in the case of hardening and softening charge-bending interaction. In the former case the charge and curvature are smoothly distributed along the chain while in the latter spontaneous kink formation is initiated. The transition to a non-circular conformation is analogous to the phase transition of the second kind.

description: The growth of supermassive black holes and their host galaxies are thought to be linked, but the precise nature of this symbiotic relationship is still poorly understood. Both observations and simulations of galaxy formation suggest that the energy input from active galactic nuclei (AGN), as the central supermassive black hole accretes material and grows, heats the interstellar material and suppresses star formation. In this Letter, we show that most host galaxies of moderate-luminosity supermassive black holes in the local universe have intermediate optical colors that imply the host galaxies are transitioning from star formation to quiescence, the first time this has been shown to be true for all AGN independent of obscuration. The intermediate colors suggest that star formation in the host galaxies ceased roughly 100 Myr ago. This result indicates that either the AGN are very long-lived, accreting for more than 1 Gyr beyond the end of star formation, or there is a ~100 Myr time delay between the shutdown of star formation and detectable black hole growth. The first explanation is unlikely given current estimates for AGN lifetimes, so low-lumiosity AGN must shut down star formation before substantial black hole accretion activity is detected. The scarcity of AGN host galaxies in the blue cloud reported here challenges scenarios where significant star formation and black hole growth are coeval. Lastly, these observations also strongly support the `Unified Model' of AGN as the host galaxy colors are independent of obscuration towards the central engine.

description: The Broad Emission Lines (BELs) in spectra of type 1 Active Galactic Nuclei (AGN) can be very complex, indicating a complex Broad Line Region (BLR) geometry. According to the standard unification model one can expect an accretion disk around a supermassive black hole in all AGN. Therefore, a disk geometry is expected in the BLR. However, a small fraction of BELs show double-peaked profiles which indicate the disk geometry. Here, we discuss a two-component model, assuming an emission from the accretion disk and one additional emission from surrounding region. We compared the modeled BELs with observed ones (mostly broad H$α$ and H$β$ profiles) finding that the model can well describe single-peaked and double-peaked observed broad line profiles.

description: THz time-domain spectroscopy (TDS) is a promising tool for quality control purposes in industrial applications, but the high cost and the relatively large laser sources still make it difficult to use the full potential of the technology for a decent price. In this work, a THz TDS system, which uses a commercially available Fabry–Perot laser diode emitting at 1550 nm, is presented. By dispersion compensation, pulses with a duration of 544 fs were generated, resulting in THz radiation with a bandwidth of 1.4 THz and a peak dynamic range of 56 dB with state-of-the-art ErAs:In(Al)GaAs photoconducting antennas. These results are compared with those of a conventional and expensive fiber laser system with a 90 fs pulse duration.

description: A proportion of youth who experience concussion develop persistent or prolonged post-concussion symptoms (PPCS). Owing to the complex clinical presentation of PPCS, an interprofessional approach to care is increasingly recommended. Despite increased research in this area, there remains a dearth of evidence from the perspective of the recipients of interprofessional concussion care. The objective of this qualitative descriptive study was to explore the experiences of youth with PPCS and their parents who participated in an interdisciplinary team-based assessment (ITA) at a children’s rehabilitation hospital in Ontario, Canada. Semi-structured interviews were conducted with fifteen individuals (eight youth [8–17 years] and seven parents). Results suggest that the ITA serves as a context for meaningful therapeutic interactions whereby youth, their parents, and the interprofessional team establish and build therapeutic relationships, engage in dialogue emphasizing collaboration, prioritize the young person rather than the injury, and co-create an individualized treatment plan. Results are discussed within the broader literature in the areas of client and family-centered care, interdisciplinary assessment, and concussion management.

The released hydrogen reacts with surrounding metals in the diamond anvil cell to form metal hydrides. A formation of rhenium hydride is observed after the decomposition of silane. From the data of a previous experimental report (Eremets et al., Science 319, 1506 (2008)), the claimed high-pressure metallic and superconducting phase of silane is identified as platinum hydride, that forms after the decomposition of silane. These observations show the importance of taking into account possible chemical reactions that are often neglected in high-pressure experiments.

description: In-hospital cardiac arrest resuscitation training often happens in silos, with minimal interprofessional training. The aim of this study was to implement and evaluate a simulation-enhanced, interprofessional cardiac arrest curriculum in a university hospital. The curriculum ran monthly for 12 months, training interprofessional teams of internal medicine residents, nurses, respiratory therapists, and pharmacy residents. Teams participated in a 90-min high-fidelity simulation including “code blue” (30 min) followed by a 30-min debriefing and a repeat identical simulated “code blue” scenario. Teams were tested in an unannounced mock Code Blue the following month. Advanced Cardiac Life Support (ACLS) algorithm adherence was assessed using a standardized checklist. In-hospital cardiac arrest (IHCA) incidence and survival was tracked for 2 years prior, during, and 1 year after curriculum implementation. Team ACLS-algorithm adherence at baseline varied from 47% to 90% (mean of 71 ± 11%) and improved immediately following training (mean 88 ± 4%, range 80–93%, p = .011). This improvement persisted but decreased in magnitude over 1 month (mean 81 ± 7%, p = .013). Medical resident self-reported comfort levels with resuscitation skills varied widely at baseline, but improved for all skills post-curriculum. This simulation-enhanced, spaced practice, interprofessional curriculum resulted in a sustained improvement in team ACLS algorithm adherence.

description: The paired preputial glands of the albino mouse, Mus musculus, (Swiss strain) were studied with regard to histology, physiology and basic histochemistry. For the histological study of the development and subsequent aging of the preputial gland, the glands of male and female mice of different ages, ranging from newborn to 12 months old, were used. In order to study the effects of androgens and estrogens upon the macroscopic and microscopic structure of the preputial gland, white Swiss mice were divided into four major groups (according to age and status) each of which were, in turn, divided into subgroups a, b, c, and d for treatment; mice in subgroups a and b received daily subcutaneous injections of testosterone propionate and of estradiol benzoate respectively; mice in subgroup creceived daily subcutaneous injections of the vehicle, sesame oil; mice in subgroup d served as controls. There were, of course, male and female mice in each grouping. Routine histochemical tests for lipids and proteins were carried out on the excised preputial glands of weanling and of young adult mice, of both sexes, in order to localize and to identify the secretory products of the acinar cells. Histologically and physiologically (in terms of response to androgens and estrogens) the preputial glands of the mouse are similar, in most respects, to those of the rat as described by other authors. However, there are apparent differences in the microscopic anatomy and in the histochemistry of these homologous organs; firstly, the presence of an intimate association of the mouse preputial gland with a central hair follicle which persists throughout the lifetime of the animal and which is not found in the rat gland; secondly, the absence of perinuclear proteinaceous granules in the acinar cells of the mouse preputial gland which are present in the acinar cells of the rat preputial gland, in addition to lipid droplets. Lipids, primarily in the form of droplets of neutral fats are, to my knowledge, the only secretory products of the mouse preputial gland. Developmentally, histologically, and histochemically, the preputial gland of the mouse is an excessively developed sebaceous gland and unlike the rat preputial gland which cannot be categorized so simply, belongs to the "monocrine" variety of holocrine gland.

description: The Cygnus region harbours a huge complex of massive stars at a distance of 1.0-2.0kpc from us. About 170 O stars are distributed over several OB associations, among which the Cyg OB2 cluster is by far the largest with about 100-120 O stars. As a consequence of their successive nuclear-burning episodes, these massive stars inject large quantities of radioactive nuclei into the interstellar medium such as 26Al and 60Fe. The gamma-ray line signal from the latter is a solid tracer of ongoing nucleosynthesis. We want to compare the decay emission from the Cygnus region with predictions of recently improved stellar models. As a first step, we establish observational constraints upon the gamma-ray line emission from 26Al and 60Fe, with particular emphasis placed on separating the emission due to the Cygnus complex from the foreground and background mean Galactic contributions. We used the high-resolution gamma-ray spectrometer INTEGRAL/SPI to analyse the 26Al and 60Fe decay signal from the Cygnus region. The weak gamma-ray line emissions at 1809 and 1173/1332keV have been characterised in terms of photometry, spectrometry, and source morphology. The 1809keV emission from Cygnus is centred on the position of the Cyg OB2 cluster and has a typical size of 9 degrees or more. The total 1809keV flux from the Cygnus region is (6.0 +/- 1.0) x10e-5 ph/cm2/s, but the flux really attributable to the Cygnus complex reduces to (3.9 +/- 1.1) x10e-5 ph/cm2/s. The 1809keV line centroid is agrees with expectations considering the direction and distance of the Cygnus complex, and the line width is consistent with typical motions of the interstellar medium. No decay emission from 60Fe has been observed from the Cygnus region and an upper limit of 1.6 x10e-5 ph/cm2/s was derived.

description: Strongly correlated states in many-body systems are traditionally created using elastic interparticle interactions. Here we show that inelastic interactions between particles can also drive a system into the strongly correlated regime. This is shown by an experimental realization of a specific strongly correlated system, namely a one-dimensional molecular Tonks-Girardeau gas.

description: Goal-oriented care is an approach to care delivery that uses patient-identified goals to drive care planning. Implementing goal-oriented care requires team members to cognitively shift the focus from “what is the matter” to “what matters to patients,” and align their mental models of what it means to care for patients. Yet, no empirical studies of goal-oriented care apply evidence from the cognitive sciences, such as Shared Mental Model (SMM) theory. We conducted a qualitative case study of an interprofessional team that adopted goal-oriented care in Vermont, US (n = 18). Guided by SMM theory, we distinguished between task-related and team-related mental models. We used framework analysis and qualitative content analysis to determine mental model content and similarity. The most shared content areas were operationalizing goal-oriented care, engaging in formal and informal communication, taking a “whole-person” approach, taking a team approach, and building trusting relationships with patients and with other team members. Trust was the only construct that spanned both task and team mental model categories, highlighting the importance of both intra-team trust and provider-patient trust to the implementation of goal-oriented care. Team members developed SMMs through training, regular meetings, and interactions during care delivery. This study provides insight into the cognitive mechanisms that underlie team-based goal-oriented care delivery, which can be used to inform implementation, training content, and future research.
On Schwinger Pair Creation in Gravity and in Closed Superstring Theory

description: We investigate the Schwinger pair creation process in the context of gravitational models with the back reaction of the electric field included in the geometry. The background is also an exact solution of type II superstring theory, where the electric field arises by Kaluza-Klein reduction. We obtain a closed formula for the pair creation rate that incorporates the gravitational back reaction. At weak fields it has the same structure as the general Schwinger formula, albeit pairs are produced by a combination of Schwinger and Unruh effect, the latter due to the presence of a Rindler horizon. In four spacetime dimensions, the rate becomes constant at strong electric fields. For states with mass of Kaluza-Klein origin, the rate has a power-like dependence in the electric field, rather than the familiar (non-perturbative) exponential dependence. We also reproduce the same formula from the string partition function for winding string states. Finally, we comment on the generalization to excited string states.

description: This study explores the geography of social inequality and intergenerational mobility in European tertiary education attainment. Analysing data from the European Social Survey (waves 1-10), this study aims to describe the potential role of national as well as regional and sub-regional contexts in shaping individual tertiary education opportunities. Results show substantial cross-country disparities, as well as a sharp divide in inequalities in tertiary education attainment within European countries. In parallel, we observe a general decline in educational inequalities over time, even if this decline is not followed by a convergence in the levels of Inequalities in Educational Opportunities (IEOs) across countries: the differences in educational inequalities between countries remain stable over time, and European countries show great variation in their trends of inequalities in tertiary education attainment over time.
