description: Успешният бизнес на една аптека се определя от голяма степен от услугите, които предлага, и цените на продуктите. Това са нещата, които различават една аптека от друга и са ключови за формирането и запазването на постоянни пациенти. Водещата хипотеза при реализацията на настоящото проучване е разбирането, че липсва нагласа за заплащане на допълнителни услуги в аптеката, свързани с профилактика и грижи за здравето. Изследването обхваща проучване на готовността за заплащане на допълнителна услуга по измерване на индекса на телесната маса, процента телесни мазнини, телесното тегло, обиколка на талията и здравния риск, свързан с повишено телесно тегло. От направеното проучване може да се посочи извода, че готовността за заплащане за тази профилактична услуга е между 5 и 7 лева. Този резултат не се влияе от други фактори като месечен доход и наличие на диагностицирано заболяване. Готовността за заплащане на допълнителна услуга в аптека е реална и би имала значим икономически ефект върху резултатите от дейността. Това би довело до привличане на допълнителни посетители в аптеката, което обосновава от маркетингова гледна точка по-масовото предлагане на подобна услуга.

Publisher: name: Zenodo
Year: 2023

description: Background—Cerebral artery dissection remains a significant cause of stroke, and the mainstay of treatment has been medical management with anticoagulation, although flow-diverting stents have been used in some cases of arterial dissection resistant to medical management. Methods—We present a case report of bilateral vertebral artery stenting using pipeline embolic device flow-diverting stents, after failed medical management of the dissection. Results—This case demonstrated substantial subsequent vertebral arterial remodeling and good clinical outcome with maintenance of posterior circulation. The patient did not suffer any further strokes or posterior circulation symptoms following vertebral artery remodeling. Conclusion—In cases where traditional management of arterial dissection has not been efficacious, flowdiverting stents may be useful in treating dissections of the posterior cerebral circulation, even with bilateral involvement.

description: We demonstrate that the Sommerfeld correction to CDM annihilations can be appreciable if even a small component of the dark matter is extremely cold. Subhalo substructure provides such a possibility given that the smallest clumps are relatively cold and contain even colder substructure due to incomplete phase space mixing. Leptonic channels can be enhanced for plausible models and the solar neighbourhood boost required to account for PAMELA/ATIC data is plausibly obtained, especially in the case of a few TeV mass neutralino for which the Sommerfeld-corrected boost is found to be $\sim10^4-10^5.$ Saturation of the Sommerfeld effect is shown to occur below $β\sim 10^{-4},$ thereby constraining the range of contributing substructures to be above $\sim 10^5\rm M_\odot.$ We find that the associated diffuse gamma ray signal from annihilations would exceed EGRET constraints unless the channels annihilating to heavy quarks or to gauge bosons are suppressed. The lepton channel gamma rays are potentially detectable by the FERMI satellite, not from the inner galaxy where substructures are tidally disrupted, but rather as a quasi-isotropic background from the outer halo, unless the outer substructures are much less concentrated than the inner substructures and/or the CDM density profile out to the virial radius steepens significantly.

Refinement of the first r-process abundance peak via high-precision mass measurements
Creators: name: Jacobs, Andrew
Publisher: name: University of British Columbia
Year: 2023

description: Since the 1960’s a general understanding of the creation of the chemical elements in the universe has existed. However, in recent decades this understanding has undergone refinement in describing the exact astrophysical mechanisms which result in the synthesis of isotopes, particularly those heavier (i.e. more protons) than iron. After the first detection of a binary neutron star merger and it’s subsequent kilonova in 2017, efforts into understanding the rapid neutron capture process (r-process) were redoubled in the form of both experimental and theoretical work. Measurements have been performed to investigate nuclei at the so-called waiting points of the r-process which result in the formation of the r-process abundance peaks. To this end, the underlying nuclear properties of the involved isotopes, specifically high-precision mass measurements of these nuclei are crucial in understanding the competition between neutron capture, photodissociation, and beta decay. In particular, the masses of ⁷⁹⁻⁸³Zn and ⁸⁵∙⁸⁶Ga have been measured. At TRIUMF’s Ion Trap for Atomic and Nuclear science (TITAN), the Multiple-Reflection Time-of-Flight Mass Spectrometer (MR-TOF-MS) provides experimental access to this property for short lived radioactive isotopes with low production rates in an environment with high backgrounds. A novel technique used at TITAN’s MR-TOF-MS for reducing background contamination, mass-selective re-trapping, was established. Mass measurement results using the TITAN MR-TOF-MS and their subsequent effect on the formation of the first r-process peak is presented. Additionally, the technique of mass-selective re-trapping is investigated in detail, and recent upgrades to the technique are discussed.

description: This work generalizes the discrete implicit Monte-Carlo (DIMC) method for modeling the radiative transfer equation from a gray treatment to an frequency-dependent one. The classic implicit Monte-Carlo (IMC) algorithm, that has been used for several decades, suffers from a well-known numerical problem, called teleportation, where the photons might propagate faster than the exact solution due to the finite size of the spatial and temporal resolution. The Semi-analog Monte-Carlo algorithm proposed the use of two kinds of particles, photons and material particles that are born when a photon is absorbed. The material particle can `propagate' only by transforming into a photon, due to black-body emission. While this algorithm produces a teleportation-free result, it is noisier results compared to IMC due to the discrete nature of the absorption-emission process. In a previous work [Steinberg and Heizler, ApJS, 258:14 (2022)], proposed a gray version of DIMC, that makes use of two kinds of particles, and therefore has teleportation-free results, but also uses the continuous absorption algorithm of IMC, yielding smoother results. This work is a direct frequency-dependent (energy-dependent) generalization of the DIMC algorithm. We find in several one and two dimensional benchmarks, that the new frequency-dependent DIMC algorithm yields teleportation-free results on one hand, and smooth results with IMC-like noise level.

description: The origin of Earth oceans is controversial. Earth could have acquired its water either from hydrated silicates (wet Earth scenario) or from comets (dry Earth scenario). [HDO]/[H2O] ratios are used to discriminate between the scenarios. High [HDO]/[H2O] ratios are found in Earth oceans. These high ratios are often attributed to the release of deuterium enriched cometary water ice, which was formed at low gas and dust temperatures. Observations do not show high [HDO]/[H2O] in interstellar ices. We investigate the possible formation of high [HDO]/[H2O] ratios in dense (nH> 1E6 cm^{-3}) and warm gas (T=100-1000 K) by gas-phase photochemistry in the absence of grain surface chemistry. We derive analytical solutions, taking into account the major neutral-neutral reactions for gases at T>100 K. The chemical network is dominated by photodissociation and neutral-neutral reactions. Despite the high gas temperature, deuterium fractionation occurs because of the difference in activation energy between deuteration enrichment and the back reactions. The analytical solutions were confirmed by the time-dependent chemical results in a 1E-3 MSun disc around a typical TTauri star using the photochemical code ProDiMo. The ProDiMo code includes frequency-dependent 2D dust-continuum radiative transfer, detailed non-LTE gas heating and cooling, and hydrostatic calculation of the disc structure. Both analytical and time-dependent models predict high [HDO]/[H2O] ratios in the terrestrial planet forming region (< 3 AU) of circumstellar discs. Therefore the [HDO]/[H2O] ratio may not be an unique criterion to discriminate between the different origins of water on Earth.

The Conceptualization and Operationalization of Diagnostic Testing in Second and Foreign Language Assessment
Creators: name: Liu, Heidi Han-Ting
Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2014

description: Diagnostic testing has long been valued by language testing researchers and practitioners for its ability to inform both teaching and learning. However, the number of well-developed diagnostic language tests is relatively low, most likely due to the difficulty in constructing a diagnostic test that incorporates a wide enough range of language skills. In recent years, the advancement of technologies has allowed for the development of several large-scale, computer-based diagnostic language tests, as well as more sophisticated measurement methods to conduct diagnosis. This article first provides the theoretical ground for how diagnosis has been conceptualized in language testing over the past 60 years. Then, several current approaches to operationalizing diagnosis in second and foreign language assessment, including both tests and methods, are reviewed. The article concludes with reflections on diagnostic testing in second and foreign language assessment at its current state, as well as recommendations for its future directions.

description: We demonstrate the fabrication of scanning superconducting quantum interference devices (SQUIDs) on the apex of sharp quartz scanning probes -- known as SQUID-on-tip probes -- using conventional magnetron sputtering. We produce and characterize SQUID-on-tips made of both Nb and MoGe with effective diameters ranging from 50 to 80 nm, magnetic flux noise down to \SI{300}{\nanoΦ_{0}/\sqrt{\hertz}}, and operating fields as high as \SI{2.5}{\tesla}. Compared to the SQUID-on-tip fabrication techniques used until now, including thermal evaporation and collimated sputtering, this simplified method facilitates experimentation with different materials, potentially expanding the functionality and operating conditions of these sensitive nanometer-scale scanning probes.

description: For compact regions Omega in R^3 with generic smooth boundary B, we consider geometric properties of Omega which lie midway between their topology and geometry and can be summarized by the term "geometric complexity". The "geometric complexity" of Omega is captured by its Blum medial axis M, which is a Whitney stratified set whose local structure at each point is given by specific standard local types. We classify the geometric complexity by giving a structure theorem for the Blum medial axis M. We do so by first giving an algorithm for decomposing M using the local types into "irreducible components" and then representing each medial component as obtained by attaching surfaces with boundaries to 4--valent graphs. The two stages are described by a two level extended graph structure. The top level describes a simplified form of the attaching of the irreducible medial components to each other, and the second level extended graph structure for each irreducible component specifies how to construct the component. We further use the data associated to the extended graph structures to compute topological invariants of Omega such as the homology and fundamental group in terms of the singular invariants of M defined using the local standard types and the extended graph structures. Using the classification, we characterize contractible regions in terms of the extended graph structures and the associated data.

Flow-diversion headaches in a patient with high-grade internal carotid artery stenosis
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Background—High-grade stenosis of the internal carotid artery (ICA) may result in flow diversion to the external carotid artery (ECA) and its branches. Head and facial pain secondary to flow-diversion to ECA and increase in regional blood flow are under-recognized and unreported. Design/methods—We report a patient with high-grade ICA stenosis and recurrent ipsilateral headaches that resolved after revascularization. Results—A 69-year-old woman presenting with right-arm weakness had neuroimaging evidence of ipsilateral high-grade ICA stenosis and left hemispheric ischemic stroke. Her history was significant for unilateral recurrent headaches that clinically resolved after left ICA angioplasty and stenting. With prior evidence supporting extracranial vasodilatation as the source of pain in migraine, and current clinical observation, we propose flow-diversion phenomenon as the connection between high-grade ICA stenosis and ipsilateral headache. Conclusion—Recognition of flow-diversion into the ECA as a possible mechanism for headaches may help in further understanding of ICA disease, its progression, and the effects of carotid revascularization on quality of life. Headache as a likely surrogate marker of carotid stenosis with flow-diversion warrants more research, and may be critical in the early identification of significant ICA stenosis and prevention of TIA or stroke

description: Charge Transfer Inefficiency (CTI) due to radiation damage above the Earth's atmosphere creates spurious trailing in Hubble Space Telescope (HST) images. Radiation damage also creates unrelated warm pixels - but these happen to be perfect for measuring CTI. We model CTI in the Advanced Camera for Surveys (ACS)/Wide Field Channel (WFC) and construct a physically motivated correction scheme. This operates on raw data, rather than secondary science products, by returning individual electrons to pixels from which they were unintentionally dragged during readout. We apply our correction to images from the HST COSMOS survey, successfully reducing the CTI trails by a factor of ~30 everywhere in the CCD and at all flux levels. We quantify changes in galaxy photometry, astrometry and shape. The remarkable 97% level of correction is more than sufficient to enable a (forthcoming) reanalysis of downstream science products, and the collection of larger surveys.

Cross-linguistic Influence in Third Language Acquisition: Factors Influencing Interlanguage Transfer

Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2013

description: In the field of Second Language Acquisition (SLA), the role of transfer has been theorized and studied to account for the influence of the native language on an interlanguage. However, stemming from behaviorist mentality, the concept of transfer has become widely associated with the direct transfer of habits and fails to take into consideration other cross-linguistic influences (CLI) that shape or are shaped by the interlanguage, such as avoidance, ‘reverse transfer’ from a learner’s second language (L2) to native language (L1), perception of linguistic distance, and interlanguage transfer. Thus, the reductionist analysis of direct L1 to L2 transfer is no longer sufficient to account for the parallel activation of languages in multilinguals.

description: Fabrics treated to repel water, superhydrophobic, and water and oil, superamphiphobic, have numerous industrial and consumer-level benefits. However, the liquid repellency decreases in the course of time. This is largely due to chemical or physical changes of the coating due to prolonged exposure to relatively harsh environments. To develop more durable fabric treatments for specific applications, it is necessary to measure the extent to which the treated fabrics retain their low-wettability after being subjected to controlled aggressive environmental conditions. In this study, plain weave fabrics made from polyester filaments and coated with silicone nanofilaments in-solution were exposed to aerodynamic icing conditions. The coated fabrics showed superhydrophobic behavior, or superamphiphobic for those that were fluorinated. The wettability of the fabrics was progressively evaluated by contact angle and roll-off-angle measurements. The coated fabrics were able to maintain their low-wettability characteristics after exposure to water droplet clouds at airspeeds up to 120 m/s, despite damage to the silicone nanofilaments, visible through scanning electron microscopy.

description: The organization, management, and production of urban space through digital information and communication technologies have become a central means for governing urban life. To overcome a lack of citizen-centered practices in today’s smart cities, governments and municipalities institutionalize citizen-centered digital infrastructures such as Decidim, a digital infrastructure proposing non-corporate, decentralized, and collaborative forms of digital production to evoke participatory governance practices and ultimately social transformation (Barandiaran et al., 2018). Swiss city administrations have adapted the Decidim platform for participatory budgeting processes and city-wide participation platforms since 2019. This article explores the process of institutional adoption, focusing on how the use of Decidim impacts local practices and negotiations for governing urban space. The examination of the Decidim platform in the Swiss cities of Zurich and Lucerne will be framed by re-conceptualizing Lefebvre’s right to the city in the age of digital transformation. The findings show that for a successful introduction of the Decidim platform based on principles of the right to the city (a) local needs for a new digital democratic instrument need to be pre-existent, (b) government employees must implement a scope of action which allows organized civil society and grassroots initiatives to appropriate the infrastructure for their own purposes, and (c) local practices of hybrid communication and organizing must be aligned with the structure of the platform. Nevertheless, digital participation tools such as Decidim cannot solve entrenched inequalities such as the financialization of land, the issue of disadvantaged neighborhoods, or the absence of voting rights for certain communities. Therefore, city administrations need to integrate hybrid participation strategies which prioritise collective power over distributive power as well as tackle urban inequalities through political means.

description: The model, introduced in a previous paper, for the description of the octupole and quadrupole degrees of freedom in conditions close to the axial symmetry, is used to describe the negative-parity band based on the first octupole vibrational state in nuclei close to the critical point of the U(5) to SU(3) phase transition. The situation of 150Nd and 152Sm is discussed in detail. The positive parity levels of these nuclei, and also the in-band E2 transitions, are reasonably accounted for by the X(5) model. With simple assumptions on the nature of the octupole vibrations, it is possible to describe, with comparable accuracy, also the negative parity sector, without changing the description of the positive-parity part.

description: Stimulated Raman adiabatic passage (STIRAP) is a well established technique for producing coherent population transfer in a three-state quantum system. We here exploit the resemblance between the Schrodinger equation for such a quantum system and the Newton equation of motion for a classical system undergoing torque to discuss several classical analogs of STIRAP, notably the motion of a moving charged particle subject to the Lorentz force of a quasistatic magnetic field, the orientation of a magnetic moment in a slowly varying magnetic field, the Coriolis effect and the inertial frame dragging effect. Like STIRAP, those phenomena occur for counterintuitively ordered field pulses and are robustly insensitive to small changes in the interaction properties.
Serial heart rate variability testing for the evaluation of autonomic dysfunction after stroke

Publisher: name: Zenodo
Year: 2023

description: Background and purpose—Autonomic dysfunction has been described as a frequent complication of stroke that could involve the cardiac, respiratory, sudomotor, and sexual systems. Cardiac autonomic dysfunction after stroke is one of the most recognized and has been described to increase the rate of mortality and morbidity. Methods—We report two cases of stroke—one hemorrhagic and one ischemic—and describe heart rate variability during the patients' hospitalizations with improvement reported for each patient several days after stroke onset. Results—The first case demonstrated autonomic dysfunction with severe reduction of HRV after a right parietal hemorrhagic stroke. The second case demonstrated similar findings in a patient with acute ischemic stroke. In both cases, normalization of heart rate variability occurred several weeks after stroke symptoms onset and was paralleled by a dramatic improvement of the clinical status. Conclusion—Our data established that serial HRV testing is a noninvasive tool that could be utilized as a marker to evaluate the dynamics of acute stroke

description: We investigate the general relativistic phase of an electromagnetic wave as it propagates in the gravitational field of the Earth, which is modeled as an isolated, weakly aspherical gravitating body. We introduce coordinate systems to describe light propagation in the Earth's vicinity along with the relevant coordinate transformations, and discuss the transformations between proper and coordinate times. We represent the Earth's gravitational field using Cartesian symmetric trace-free (STF) mass multipole moments. The light propagation equation is solvable along the trajectory of a light ray to all STF orders $\ell$. Although we focus primarily on the quadrupole ($\ell=2$), octupole ($\ell=3$), and hexadecapole ($\ell=4$) cases, our approach is valid to all orders. We express the STF moments via spherical harmonic coefficients of various degree and order, $C_{\ell k}, S_{\ell k}$. The result is the gravitational phase shift expressed in terms of the spherical harmonics. These results are new. We also consider contributions due to tides and the Earth's rotation. We estimate the characteristic magnitudes of each term of the resulting overall gravitational phase shift. The terms assessed are either large enough to impact current-generation clocks or will become significant as future-generation clocks offer greater sensitivity. Our formulation is useful for many practical and scientific applications, including space-based time and frequency transfers, relativistic geodesy and navigation, as well as quantum communication links and space-based tests of fundamental physics.

Written Corrective Feedback: A Review of Studies since Truscott (1996)
Creators: name: Meng, Yuan-Yuan
Publisher: name: Studies in Applied Linguistics and TESOL
Year: 2013

description: Linguistic errors are pervasive in second language (L2) students’ writing. Depending on their gravity, the errors may cause a minor degree of irritation to the reader or even lead to total communication breakdown. As such, errors have always been a major concern to both students and teachers, and error correction has also assumed a central position in language teaching. Students generally expect that their errors will be pointed out and dealt with by their teachers. For L2 teachers, providing written corrective feedback (CF) on student writing has long been an essential practice. In fact, “grammar correction is something of an institution” (Truscott, 1996, p. 327) in L2 writing courses. Despite the fact that correcting students’ written errors is a time-consuming ordeal, and the endeavor is “fraught with uncertainty about its long-term effectiveness” (Ferris, 1999, p. 1), most L2 teachers have continued to slave over students’ errors in one form or another. As confirmed by a recent study on practitioners’ perspectives, the majority of teachers believe that students need CF and that written CF is overall an effective pedagogical practice (Evans et al., 2010).

description: We study predictions for dark matter phase-space structure near the Sun based on high-resolution simulations of six galaxy halos taken from the Aquarius Project. The local DM density distribution is predicted to be remarkably smooth; the density at the Sun differs from the mean over a best-fit ellipsoidal equidensity contour by less than 15% at the 99.9% confidence level. The local velocity distribution is also very smooth, but it differs systematically from a (multivariate) Gaussian distribution. This is not due to the presence of individual clumps or streams, but to broad features in the velocity modulus and energy distributions that are stable both in space and time and reflect the detailed assembly history of each halo. These features have a significant impact on the signals predicted for WIMP and axion searches. For example, WIMP recoil rates can deviate by ~10% from those expected from the best-fit multivariate Gaussian models. The axion spectra in our simulations typically peak at lower frequencies than in the case of multivariate Gaussian velocity distributions. Also in this case, the spectra show significant imprints of the formation of the halo. This implies that once direct DM detection has become routine, features in the detector signal will allow us to study the dark matter assembly history of the Milky Way. A new field, "dark matter astronomy", will then emerge.

description: Thanks to the recent advent of the event horizon telescope (EHT), we now have the opportunity to test the physical ramifications of the strong-field near-horizon regime for astrophysical black holes. Herein, emphasizing the trade-off between tractability and generality, the authors discuss a particularly powerful three-function distortion of the Kerr spacetime, depending on three arbitrary functions of the radial coordinate $r$, which on the one hand can be fit to future observational data, and on the other hand is sufficiently general so as to encompass an extremely wide class of theoretical models. In all of these spacetimes, both the timelike Hamilton--Jacobi (geodesic) and massive Klein--Gordon (wave) equations separate, and the spacetime geometry is asymptotically Kerr; hence these spacetimes are well-suited to modelling real astrophysical black holes. The authors then prove the existence of Killing horizons for this entire class of spacetimes, and give tractable expressions for the angular velocities, areas, and surface gravities of these horizons. We emphasize the validity of rigidity results and zeroth laws for these horizons.

description: Telecollaboration refers to the use of online communication tools to connect language learners in different countries in collaborative projects and intercultural exchange (Belz, 2001). The last twenty years mark an intensive period of research in online interactions and intercultural exchange. The growth of telecollaboration and online foreign language (FL) interaction in educational settings is irrefutable. This is clearly evident in the volume and concentration of research on it and its related topics, with research developing in parallel to and closely reflecting the unfolding of online interaction and exchange in the field of foreign language education (Reinhardt & Thorne, 2011). Conscious of the wide variety of approaches, paradigms, and challenges that researchers are confronted with when approaching the field of online interaction and exchange in FL education, this book presents a comprehensive guide for practitioners and newcomers alike by two of the veterans in the field, M. Dooly and R. O’Dowd.

description: We present the first application of the Poisson-Wiseman-Anderson method of matched expansions, to compute the self-force acting on a point particle moving in a curved spacetime. The method uses two expansions for the Green function, valid in `quasilocal' and `distant past' regimes, which are matched within the normal neighbourhood. We perform our calculation in a static region of the spherically symmetric Nariai spacetime (dS_2 x S^2), on which scalar perturbations are governed by a radial equation with a Pöschl-Teller potential. We combine (i) a very high order quasilocal expansion, and (ii) an expansion in quasinormal modes, to determine the Green function globally. We show it is singular everywhere on the null wavefront (even outside the normal neighbourhood), and apply asymptotic methods to determine its singular structure. We find the Green function undergoes a transition every time the null wavefront passes through a caustic: the singular part follows a repeating four-fold sequence $δ(σ)$, $1/πσ$, $-δ(σ)$, $-1/πσ$ etc., where $σ$ is Synge's world function. The matched expansion method provides new insight into the non-local properties of the self-force; we find the contribution from the segment of the worldline lying outside the normal neighbourhood is significant. We compute the scalar self-force acting on a static particle, and validate against an alternative method. Finally, we discuss wave propagation on black hole spacetimes (where any expansion in quasinormal modes will be augmented by a branch cut integral) and predict that the Green function in Schwarzschild spacetime will inherit the four-fold singular structure found here.

Momentum dependent nucleon-nucleon contact interaction from a relativistic Lagrangian

description: A complete set of parity- and time-reversal conserving relativistic nucleon-nucleon contact operators is identified up to the order $O(p^4)$ of the expansion in soft momenta $p$. A basis is also provided for the corresponding non-relativistic operators contributing in the general reference frame. We show that the non-relativistic expansions of the relativistic operators involve twenty-six independent combinations, two starting at $O(p^0)$, seven at order $O(p^2)$ and seventeen at order $O(p^4)$. This gives supporting evidence to the existence of two free low-energy constants which parametrize an interaction depending on the total nucleon pair momentum ${\bf P}$, and were recently found to be instrumental for the resolution of the long standing $A_y$ problem in low-energy $p-d$ scattering. Furthermore, all remaining ${\bf P}$-dependent interactions at the same order are uniquely determined as relativistic corrections.

Fire-climate relationships in continental Southeast Asia
Creators: name: Ku, Andrea
Publisher: name: University of British Columbia
Year: 2023

description: Despite the prevalence of fire in continental Southeast Asia (SEA) and its important ecological role, little is known about the drivers of geographical variation of fire activity in the region. My research investigated 1) how the geographic variation in fire activity is associated with climate, landcover, and human influence, and 2) what and where are distinct fire regimes located in continental SEA. I quantified the response of fire activity to climate, landcover, and anthropogenic metrics and defined spatially constrained clusters with similar fire patterns. We used satellite remote-sensing data from 2001 to 2021 at 0.25° spatial resolutions. Climatic variables that decrease vegetation moisture and the presence of human establishments were important predictors of fire activity. We identified fire regimes that were associated with deforestation in Cambodia and Laos, agricultural activity in Vietnam, and ecological fires in the forest-savanna mosaics in Cambodia. Exploring the spatial distribution of fire patterns and its’ anthropogenic or climatological drivers of fire is key to understanding Southeast Asian ecosystems. Implications of these results could further encourage ecologically appropriate fire management strategies.
title: Economic theory and political thought in German social democracy : An essay in the 'Rezeption' of Marx's Capital with particular reference to Kautsky, Parvus, Hilferding and Luxemburg
Creators: name: Pugh, G. T
Publisher: name: University of Kent
Year: 2022

description: This thesis investigates the political import of economic theory and analysis within German social democracy. Part I (Ch. 1) briefly discusses the Lassallean origins of social democracy with reference to Lassalle's economic doctrines. It continues (in Ch. 2) by analysing the prime contribution of Marx's Capital to shaping the Marxism that displaced Lassalleanism, and came to be embodied in the Erfurt Programme. as the SPD's official doctrine. The main results of my research, however, are presented in the four chapters of Part II. Here, I approach the Political logic and influence of economic theory, by way of case studies of four politically influential social democratic economic theorists: Karl Kautsky; Parvus; Rudolf Hilferding; and Rosa Luxemburg. In addition to developing the main theme of this thesis, each of these may be taken as a contribution to the literature on these particular theorists, as well as to the historiography of German social democracy (in particular, in the period 1890-1914). Marx's Capital was the basis of social democratic economic theory in the period under consideration. Consequently, analysing the development and political implications of social democratic economic theory contributes to the study of the appropriation, interpretation and influence - the 'Rezeption', in short - of Capitol. Moreover, in so doing, I attempt to provide a theoretical critique, and to indicate the actual content as well as methodological shortcomings, misinterpretations and lacunae in the social democratic 'Rezeption' of Capital. My theoretical critique is undertaken from a 'fundamentalist' interpretation of Capital, and illuminates the theoretical limitations - together with the political implications - of the most advanced attempts to move beyond the Erfurt Programme towards a scientific guide to political action in the imperialist epoch. Finally, this thesis is also intended as a minor contribution to the political reading of Capital.
Conceptual Dynamics in Multilingual Competence

description: Mulitlingualism represents the capacity of linguistic communities and individuals to regularly use more than one language on a daily basis (Franceschini, 2011). Recently, mounting theoretical and empirical studies on multilingualism have emerged within the field of applied linguistics. Among such analyses, there has been much attention on the notion of multicompetence, which places a psycholinguistic/cognitive lens upon the study of multilingual minds (e.g., Bassetti & Cook, 2011; Brown & Gullberg, 2012). This piece will briefly explore multicompetence with regards to the influence of language(s) on the conceptual structures of multilingual speakers. In relation to this, a brief discussion on the dynamic nature of multilingual competence from the conceptual lens will also be provided.

Neuroanatomical correlates of atrial fibrillation: a longitudinal MRI study
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Background and purpose—To determine baseline volume and rate of volume change of whole brain, hippocampus, and entorhinal cortex in patients with atrial fibrillation. Methods—We analyzed clinical and neuroimaging data collected as part of Alzheimer's Disease Neuroimaging Initiative in the United States and Canada. Patients with atrial fibrillation were identified based on baseline clinical/cognitive assessments, and age and gender-matched controls without atrial fibrillations were selected (1:1 ratio). All participants underwent 1.5 T structural magnetic resonance imaging (MRI) at specified intervals (6 or 12 months) for 2–3 years. Results—A total of 33 persons with atrial fibrillation were included. There was no difference in whole brain and ventricular volumes at baseline MRI between cases and controls. There was significantly lower entorhinal cortex volume on right (p = 0.01) and left (p = 0.01) sides in patients with atrial fibrillation. There was significantly lower volume for middle temporal lobes on right (p = 0.04) and left (p = 0.001) sides. The rate of progression of atrophy in entorhinal cortex and middle temporal lobes was not different between patients with atrial fibrillation and controls. Conclusions—The association of atrial fibrillation with volume loss in entorhinal cortex and middle temporal lobes may provide new insights into pathophysiology of atrial fibrillation
The Role of Metalinguistic Awareness in Multilingual Acquisition

description: Multilingual acquisition is a nonlinear and complex dynamic process. The past several decades of research have revealed that a number of factors interact and influence the variability of the process, including, for instance, the type of third language (L3) learner, learner proficiency, linguistic domain, grammatical feature, and language (psycho)typology (e.g., Cabrelli Amaro & Rothman, 2010; Llama, Cardoso, & Collins, 2010; Cenoz & Valencia, 1994; Gallardo del Puerto, 2007; Gibson, Hufeisen, & Libben, 2001; Pittman, 2008; Ringbom, 2001). Yet another crucial factor to consider, especially from the recent perspective of the Dynamic Model of Multilingualism (DMM) (Herdina & Jessner, 2002), is the linguistic background of the learner in relation to their literacy in the second language (L2), and more specifically, their metalinguistic knowledge and awareness (De Bot & Jaensch, 2013).
