description: Young stars are formed within dusty discs. The grains in the disc are originally of the same size as interstellar dust. Models predict that these grains will grow in size through coagulation. Observations of the silicate features at micron wavelengths are consistent with growth to micron sizes whereas the slope of the SED at longer wavelengths traces growth up to mm sizes. We here look for a correlation between these two grain growth indicators. A large sample of T-Tauri and Herbig-Ae/Be stars was observed with the Spitzer Space Telescope at 5-13 micron; a subsample was observed at mm wavelengths. We complement this subsample with data from the literature to maximise the overlap between micron and mm observations and search for correlations. Synthetic spectra are produced to determine which processes may produce the dust evolution. Dust disc masses in the range <1 to 7 x 10^-4 MSun are obtained. Most sources have a mm spectral slope consistent with grain growth. There is a tentative correlation between the 10-micron silicate feature and the mm slope of the SED. The observed sources seem to be grouped per star-forming region in the micron-vs-mm diagram. The modelling results show that the 10-micron feature becomes flatter and subsequently the mm slope becomes shallower. Grain size distributions shallower than that of the ISM and/or bright central stars are required to explain specific features. Settling of larger grains towards the disc midplane affects the 10-micron feature, but hardly the mm slope. The tentative correlation between the strength of the 10-micron feature and the mm slope suggests that the inner and outer disc evolve simultaneously. Dust with a mass dominated by mm-sized grains is required to explain the shallowest mm slopes. Other processes besides grain growth may also be responsible for the removal of small grains.

Oxygenation and radiosensitization consequences of solid tumour perfusion
Creators: name: Wadsworth, Brennan
Publisher: name: University of British Columbia
Year: 2020

description: Solid tumours often develop regions that are poorly oxygenated (hypoxic). Hypoxic tumour cells are resistant to radiation and are associated with poor patient outcome. “Chronic hypoxia” develops where vascular density is insufficient, causing tumour cells beyond ~70-100 μm from blood vessels to receive little oxygen. “Transient hypoxia” occurs in solid tumours where fluctuating microregional perfusion exposes tumour cells to cycles of hypoxia and reoxygenation. The fundamental understanding of transient hypoxia in vivo is lacking, and there are no available strategies to eliminate transient hypoxia. This thesis hypothesizes that transiently hypoxic tumour cells are long-lived radiation resistant cells and that eliminating the development of transient hypoxia will improve tumour radiation response. This thesis first investigated the rate of hypoxic cell turnover in vivo. Exogenous hypoxia reporters were used to label hypoxic tumour cells, while loss of labelled cells over time indicated loss of hypoxic cells. The perfusion-modifying drug pentoxifylline was used to control which hypoxic populations were labelled and therefore which populations were lost over time. We find that transiently hypoxic tumour cells survive longer than neighbouring chronically hypoxic cells, further justifying transient hypoxia as an important therapeutic target. To better study tumour perfusion-modifying interventions, this thesis next validated 2-18F-fluoroethanol as a novel reporter of solid tumour perfusion compatible with positron emission tomography. We found 2-18F-fluoroethanol to effectively respond to established tumour perfusion-modifying interventions and applied 2-18F-fluoroethanol to characterize novel interventions aiming to modify tumour perfusion and transient hypoxia. This thesis then focused on the angiotensin II type 1 receptor blocker telmisartan. Telmisartan treatment reduced tumour collagen 1 content, increased and stabilized tumour perfusion, reduced the development of transient hypoxia, and improved tumour radiation response. This presents the target of telmisartan, cancer associated fibroblast activity and tumour collagen 1 content, as a potential microenvironmental cause of transient hypoxia. Overall, this thesis provides insight into the basic biology of transient hypoxia in vivo, validates a novel non-invasive reporter of solid tumour perfusion, and identifies telmisartan as a clinically relevant treatment to stably reduce the development of transient hypoxia in solid tumours and improve radiation response.

description: We study the motion of a string in the background of the Schwarzschild black hole in AdS_5 by applying the standard arsenal of dynamical systems. Our description of the phase space includes: the power spectrum, the largest Lyapunov exponent, Poincare sections and basins of attractions. We find convincing evidence that the motion is chaotic. We discuss the implications of some of the quantities associated with chaotic systems for aspects of the gauge/gravity correspondence. In particular, we suggest some potential relevance for the information loss paradox.

description: Transcranial alternating current stimulation (tACS) can affect perception, learning and cognition, but the underlying mechanisms are not well understood. A promising strategy to elucidate these mechanisms aims at applying tACS while electric or magnetic brain oscillations targeted by stimulation are recorded. However, reconstructing brain oscillations targeted by tACS remains a challenging problem due to stimulation artifacts. Besides lack of an established strategy to effectively supress such stimulation artifacts, there are also no resources available that allow for the development and testing of new and effective tACS artefact suppression algorithms, such as adaptive spatial filtering using beamforming or signal-space projection. Here, we provide a full dataset comprising encephalographic (EEG) recordings across six healthy human volunteers who underwent 10-Hz amplitude-modulated tACS (AM-tACS) during a 10-Hz steady-state visually evoked potential (SSVEP) paradigm. Moreover, data and scripts are provided related to the validation of a novel stimulation artefact suppression strategy, Stimulation Artifact Source Separation (SASS), removing EEG signal components that are maximally different in the presence versus absence of stimulation. Besides including EEG single-trial data and comparisons of 10-Hz brain oscillatory phase and amplitude recorded across three conditions (condition 1: no stimulation, condition 2: stimulation with SASS, condition 3: stimulation without SASS), also power spectra and topographies of SSVEP amplitudes across all three conditions are presented. Moreover, data is provided for assessing nonlinear modulations of the stimulation artifact in both time and frequency domains due to heartbeats. Finally, the dataset includes eigenvalue spectra and spatial patterns of signal components that were identified and removed by SASS for stimulation artefact suppression at the target frequency. Besides providing a valuable resource to assess properties of AM-tACS artifacts in the EEG, this dataset allows for testing different artifact rejection methods and offers in-depth insights into the workings of SASS.

description: Este artigo resulta de uma pesquisa conduzida numa escola profissional no centro do país em que se tentou entender que novas práticas digitais foram ensaiadas aquando dos períodos de confinamento, em 2020-21 e 2021-22, no âmbito da pandemia Covid-19. Esta situação determinou a passagem brusca de um regime de ensino presencial a um regime de ensino à distância. Através de questionários, entrevistas individuais e em grupo (focus group) e de uma observação participante com registo em diário de campo, foi possível constatar as mudanças induzidas e de como elas afetaram o quotidiano de docentes e discentes e suas respetivas famílias. Estes efeitos foram aparentemente diferenciados em função da condição sociocultural e económica dos jovens e suas famílias.

description: Intense electric field $\sim 10^{10}-10^{11}$ V/cm in crystal has been known for a long time and has wide applications. We study the conversion of axion-like light particle and photon in the intense electric field in crystal. We find that the conversion of axion-like particle and photon happens for energy larger than keV range. We propose search of axion-like light particle using the intense crystalline field. We discuss the solar axion search experiment and a variety of shining-through-wall experiment using crystalline field. Due to the intense crystalline field which corresponds to magnetic field $\sim 10^4-10^5$ Tesla these experiments are very interesting. In particular these experiments can probe the mass range of axion-like particle from eV to keV.

description: Purpose: Besides diagnostic imaging devices, in particular computed tomography (CT) and magnetic resonance imaging (MRI), numerous reading workstations contribute to the high energy consumption of radiological departments. It was investigated whether switching off workstations after core working hours can relevantly lower energy consumption considering both ecological and economical aspects. Methods: Besides calculating different theoretical energy consumption scenarios, we measured power consumption of 3 workstations in our department over a 6-month period under routine working conditions and another 6-month period during which users were asked to switch off workstations after work. Staff costs arising from restarting workstations manually were calculated. Results: Our approach to switching off workstations after core working hours reduced energy consumption by about 5.6 %, corresponding to an extrapolated saving of 3.2 tons in carbon dioxide (CO2) emissions and 2100.70 USD/year in electricity costs for 227 workstations. Theoretical calculations indicate that consistent automatic shutdown after core working hours could result in a potential total reduction of energy consumption of 38.6 %, equaling 22.2 tons of CO2 and 14,388.28 USD/year. However, staff costs resulting from waiting times after manually restarting workstations would amount to 36,280.02 USD/year. Conclusions: Switching off workstations after core working hours can considerably reduce energy consumption and costs, but varies with user adherence. Staff costs caused by waiting time after manually starting up workstations outweigh energy savings by far. Therefore, an energy-saving plan with automated shutdown/restart besides enabling an energy-saving mode would be the most effective way of saving both energy and costs.

description: Sustainability in tourism assumes the balance among the economic, environmental, cultural, and social dimensions that intervene in its activities to optimize its benefits, without any prejudice to society and the environment. In this sense, there is a worldwide movement to make the tourism sector agents aware, with the intention of broadening sustainable and practical actions. With this perspective, this study aimed to verify the current state of the activities performed by the tourism sector in Brazil regarding the determinations (criteria, principles and goals) developed by national and international institutions. Through descriptive research with a quantitative approach, stakeholders linked to the Brazilian tourism sector participated in this study. The results showed that in Brazil there is still a need for more involvement and cooperation among residents, tourists and tourism operators linked to the tourism sector, with a commitment to sustainably balance the economic, environmental, cultural and social dimensions of its activities. It was also found that the environmental dimension was portrayed as having the least compliance with sustainability, that is, the activities of the Brazilian tourism sector are the ones that are the most deficient and require the largest investment.

Subjects: Slow City; Civil Society; Tourism Degrowth; Politicization; Growth

description: Despite general support for economic growth, the benefit of continued expansion of tourism is being increasingly questioned in favor of more inclusive forms of tourism development. Degrowth can be politicized if public opinion becomes skeptical about tourism development. The slow city international network, which provides a transnational sphere for politicizing tourism degrowth, has connections to local slow cities to enable politicization at the regional and national level. The present study focused on the first slow city in Turkey, namely Seferihisar in the city of Izmir. It is an exploratory research with the qualitative research design based on semi-structured interviews. By adapting the domestic politicization model to tourism growth and drawing on the case of slow city of Seferihisar, this study shows how a mismatch between expectations and existing conditions can activate the public policy sphere, while the logics of distribution and identity can be articulated in line with the slow city cultural model.

description: The system of electricity supply 750/330 kV was studied. Elements of power supply system, such as transformers and OHL, were chosen. In addition this, steady state calculations were performed using both analytical methods and RastrWIN software. On-peak and off-peak loading conditions were considered at calculation. The currents and voltages were determined for a one-phase short circuit at the conjunction point of the line and autotransformer. Vector diagram were plotted. In the final part of the work, the dynamic stability of the system was investigated using the Dymola software.

description: La finalità di questo lavoro di ricerca è quella di indagare come, attraverso la rappresentazione artistica e l’acquisizione di concetti elementari sulle nubi, la riproduzione delle stesse possa evolversi aiutando un alunno del secondo ciclo di scuola elementare a comprendere meglio quanto disegnato. Si sono quindi raccolte le conoscenze iniziali della classe-campione sia in ambito grafico-pittorico che in ambito scientifico e, a partire da esse, è stato strutturato un percorso didattico che ha permesso di affrontare da più punti di vista il tema delle nuvole. Confrontando i dati raccolti nel primo intervento e quelli finali si notano enormi progressi non solo nelle conoscenze scientifiche acquisite ma anche nella capacità di riprodurre delle nubi che non presentano la forma stereotipata, evidenziata, ad inizio ricerca, nella grande maggioranza dei casi. Oltre a questo, nelle produzioni si nota l’influenza che le attività di copia, sia quelle eseguite in presa diretta che la riproduzione di un dipinto del pittore John Constable, hanno avuto sugli allievi; se si osservano i disegni, tra i quali anche quelli finali, si notano infatti forme e colori particolari che in taluni casi rievocano le rappresentazioni eseguite in precedenza. I dati ci confermano la possibilità di un travaso di conoscenze da una materia all’altra anche in alunni del secondo ciclo e mostrano chiaramente come il disegno si riveli un mezzo efficace per favorire l’apprendimento e le conoscenze dei bambini.

description: Policy makers, policy advisers and the general public frequently perceive events as beneficial to the economy of the host city. Such belief is supported by numerous Economic Impact studies, often based on Input-Output models, which usually exhibit large positive impacts. However, research has identified potential issues in Economic Impact studies that may result in misguiding policy recommendations. Yet, no systematic presentation of such potential flaws is available to the researcher and the practitioners. To fill in this gap, this article proposes a set of criteria based on 7 categories and 32 criteria and applies them to the latest mega events held in Italy. This application supports the value of our proposed criteria and suggests that the claims based on existing studies are debatle.

description: This case report presents the diagnostic workup of liver malignancy incidentally detected in a 72-year-old male patient on routine body computed tomography angiography (CTA) performed for planning transcatheter aortic valve implantation (TAVI). The patient initially presented to an outside hospital with chest discomfort, where routine diagnostic procedures in the emergency room revealed grade III aortic valve stenosis. Routine CTA for TAVI planning in our department then revealed tumor thrombosis of the portal vein suspicious for hepatic malignancy. In contrast-enhanced ultrasound (CEUS) only the left hepatic lobe was inhomogeneously transformed with early arterial contrast enhancement. Magnetic resonance imaging (MRI) confirmed a primary hepatic malignancy involving the left liver. Transcutaneous biopsy with ultrasound guidance established the diagnosis of hepatocellular carcinoma (HCC). Incidental findings may be of prognostic relevance for the patient and in a number of cases, TAVI can be a prerequisite for the appropriate therapy.

description: We use photometric and spectroscopic infrared observations obtained with the Spitzer Space Telescope of 12 radio-loud active galactic nuclei (AGN) to investigate the dust geometry. Our approach is to look at the change of the infrared spectral energy distribution (SED) and the strength of the 10 micron silicate feature with jet viewing angle. We find that (i) a combination of three or four blackbodies fits well the infrared SED; (ii) the sources viewed closer to the jet axis appear to have stronger warm (~300 - 800 K) and cold (~150 - 250 K) dust emissions relative to the hot component; and (iii) the silicate features are always in emission and strongly redshifted. We test clumpy torus models and find that (i) they approximate well the mid-infrared part of the SED, but significantly underpredict the fluxes at both near- and far-infrared wavelengths; (ii) they can constrain the dust composition (in our case to that of the standard interstellar medium); (iii) they require relatively large (~10%-20% the speed of light) redward displacements; and (iv) they give robust total mass estimates, but are insensitive to the assumed geometry.

description: Background: Symptom checkers (SCs) are tools developed to provide clinical decision support to laypersons. Apart from suggesting probable diagnoses, they commonly advise when users should seek care (triage advice). SCs have become increasingly popular despite prior studies rating their performance as mediocre. To date, it is unclear whether SCs can triage better than those who might choose to use them. Objective: This study aims to compare triage accuracy between SCs and their potential users (ie, laypersons). Methods: On Amazon Mechanical Turk, we recruited 91 adults from the United States who had no professional medical background. In a web-based survey, the participants evaluated 45 fictitious clinical case vignettes. Data for 15 SCs that had processed the same vignettes were obtained from a previous study. As main outcome measures, we assessed the accuracy of the triage assessments made by participants and SCs for each of the three triage levels (ie, emergency care, nonemergency care, self-care) and overall, the proportion of participants outperforming each SC in terms of accuracy, and the risk aversion of participants and SCs by comparing the proportion of cases that were overtriaged. Results: The mean overall triage accuracy was similar for participants (60.9%, SD 6.8%; 95% CI 59.5%-62.3%) and SCs (58%, SD 12.8%). Most participants outperformed all but 5 SCs. On average, SCs more reliably detected emergencies (80.6%, SD 17.9%) than laypersons did (67.5%, SD 16.4%; 95% CI 64.1%-70.8%). Although both SCs and participants struggled with cases requiring self-care (the least urgent triage category), SCs more often wrongly classified these cases as emergencies (43/174, 24.7%) compared with laypersons (56/1365, 4.10%). Conclusions: Most SCs had no greater triage capability than an average layperson, although the triage accuracy of the five best SCs was superior to the accuracy of most participants. SCs might improve early detection of emergencies but might also needlessly increase resource utilization in health care. Laypersons sometimes require support in deciding when to rely on self-care but it is in that very situation where SCs perform the worst. Further research is needed to determine how to best combine the strengths of humans and SCs.
Sharing Economy: The Relationship between Airbnb, the Accommodation Industry and New Tourist Flows. The Case of Bologna Metropolitan Area (Italy)
Creators: name: Beghelli, Matteo
Publisher: name: Almatourism - Journal of Tourism, Culture and Territorial Development
Year: 2020
Subjects: Sharing hospitality; Sharing economy; Over-Tourism; Urban competition; Bologna

description: The aim of this paper is to assess the relationship between tourist accommodations managed through sharing-economy portals and the tourist facilities professionally managed (typically hotels) in terms of direct and indirect competition. Moreover, the analysis of the turnover associated with different kinds of facilities bookable on Airbnb, the most widely used sharing-economy portal for tourism, allow to assess the ratio of “core sharing” (the sharing-economy in its proper meaning) in Airbnb business and to estimate new tourist flows brought about by the portal. The analysis has been carried out for the metropolitan area of Bologna (Italy) in the years 2015-18. This work shows that only 20% of the turnover recorded by Airbnb in Bologna metro area can be associated to “pure” sharing-economy, meanwhile the remaining 80% have various levels of professional management that, in many cases (though not all), undermine the peer-to-peer nature of the relationship established between the parties involved (peer-to-peer relationship is a must of proper sharing-economy). Of this 80% of turnover, while 44% is associated with facilities that can be considered in direct competition with hotels, 36% is made by tourist accommodations that, to a various degrees, play indirect competition with hotels, thus activating new tourist flows towards Bologna metro area.

Return to learn and concussion management teams: school psychologists' current practices and perceptions
Creators: name: Slemp, Jacqueline Ann
Publisher: name: No Publisher Supplied
Year: 2021

description: Researchers have argued that to support students effectively following a concussion, prompt and comprehensive action by schools is needed to help students readjust to classroom demands. While many researchers and practitioners have advocated for school psychologists’ involvement in this process, research has not explored in detail what school psychologists currently do regarding concussion management or their perceptions about the use of concussion management teams within their ecological contexts. This study surveyed school psychologists within the state of New Jersey (n = 151) to investigate current practices and perceptions regarding pediatric concussion management in school contexts. Results indicated that 42.38% of the respondents have engaged in concussion management in the past, and nearly all participants (i.e., 95.36%) agreed that implementing supports for students following a concussion is aligned with their role as a school psychologist. The current study not only illuminated a gap between school psychologists’ beliefs that concussion management is aligned with their role and the extent to which they are involved, but it also highlighted a discrepancy between the need for supports in schools following concussions and the limited number of formalized concussion management teams and return-to-learn procedures. The present study additionally adds to the current literature suggesting that school psychologists are in a unique position to help students return to school following a concussion. The findings suggest that the effects of formal training on practices and perceptions of concussion management should be further explored in the future. Additional implications for schools and suggestions for future research are discussed.

Pedagogical potential in the complexism learning process : a performer's journey through Brian Ferneyhough's "Bone Alphabet" (1992)
Creators: name: Graham, Aaron
Publisher: name: University of British Columbia
Year: 2020

description: When performers decide to take on the substantial task of learning and performing a piece of music in the style known as complexism (more typically called “New Complexity”), they are faced with technical and interpretive challenges of a hyper-virtuosic nature. These demands are far beyond what is typically found in the majority of other musical contexts and therefore can be daunting to the performer. This thesis focuses on the pedagogical potentials inherent in the learning process of a complexist work. Included are interviews with major performers of this style of music and their insights into the benefits of such a specialized learning context. Following this, a detailed analysis is provided of my own experience learning and performing Brian Ferneyhough’s “Bone Alphabet,” (1992) a solo percussion work in this style, with supporting video demonstrations. This discussion is complemented by the presentation of strategies for performers to surmount the technical and interpretive difficulties found in complexism. Complexism and the choice to take it on have faced criticism over the years, with arguments being that the abundance of compositional material is too much for a performer to properly realize, attempts to prepare the works yield only approximations that sound like improvisations, and that the amount of time needed to prepare a work is not beneficial at all to the performer. However, my experience learning “Bone Alphabet,” and the processes and choices I was required to make as a student of this style have helped to inform and serve numerous aspects of my musicianship in other contexts, such as increased technical facility in executing complex rhythms and more thoughtful and rigorous score study and interpretation. Through an analysis of my own experience as well as expert testimonials regarding this unique musical context, this thesis will illuminate the pedagogical potentials inherent in the learning process for works of musical complexism.
