Abstract
Debris disks are dusty, optically thin structures around main-sequence stars. HD 106906AB is a short-period stellar binary, host to a wide-separation planet, HD 106906b, and a debris disk. Only a few known systems include a debris disk and a directly imaged planet, and HD 106906 is the only one in which the planet is exterior to the disk. The debris disk is edge-on and highly asymmetric in scattered light. Here we resolve the disk structure at a resolution of 0.″38 (39 au) with the Atacama Large Millimeter/submillimeter Array (ALMA) at a wavelength of 1.3 mm. We model the disk with both a narrow and broad ring of material, and find that a radially broad, axisymmetric disk between radii of ∼50–100 au is able to capture the structure of the observations without evidence of any asymmetry or eccentricity, other than a tentative stellocentric offset. We place stringent upper limits on both the gas and dust contents of a putative circumplanetary disk. We interpret the ALMA data in concert with scattered-light observations of the inner ring and astrometric constraints on the planet’s orbit, and find that the observations are consistent with a large-separation, low-eccentricity orbit for the planet. A dynamical analysis indicates that the central binary can efficiently stabilize planetesimal orbits interior to ∼100 au, which somewhat relaxes the constraints on the eccentricity and semimajor axis. The observational constraints are consistent with in-situ formation via gravitational instability but cannot rule out a scattering event as the origin for HD 106906b’s current orbit.

Abstract
Observational data from the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory and the multiwavelength simultaneous imaging system attached to the New Vacuum Solar Telescope located at Fuxian Lake, China are employed for the study of light bridges and magnetic fields in the active region NOAA 12529. Coronal fields in this active region are computed with a boundary integration model and the field line connectivity in the dominant spot is investigated with the squashing factor Q. Quasi separatrix layer intersections in the CCD coordinate plane are determined according to values of Q. It is found that weak field lanes (WFLs) appear in the umbra and penumbra; open and closed flux systems are separated by QSLs in the dominant spot; and WFLs and QSLs look quite different from each other in the dominant spot but partially overlap in the umbra. Our study demonstrates that WFLs cannot be attributed to topological evolution of magnetic fields and might be regarded as rifts among splitting flux systems.

Abstract
The dispersion in chemical abundances provides a very strong constraint on the processes that drive the chemical enrichment of galaxies. Due to its proximity, the spiral galaxy M33 has been the focus of numerous chemical abundance surveys to study the chemical enrichment and dispersion in abundances over large spatial scales. The CHemical Abundances Of Spirals project has observed ∼100 H ii regions in M33 with the Large Binocular Telescope (LBT), producing the largest homogeneous sample of electron temperatures (T

e
) and direct abundances in this galaxy. Our LBT observations produce a robust oxygen abundance gradient of −0.037 ± 0.007 dex kpc−1 and indicate a relatively small (0.043 ± 0.015 dex) intrinsic dispersion in oxygen abundance relative to this gradient. The dispersions in N/H and N/O are similarly small, and the abundances of Ne, S, Cl, and Ar relative to O are consistent with the solar ratio as expected for α-process or α-process-dependent elements. Taken together, the ISM in M33 is chemically well-mixed and homogeneously enriched from inside out, with no evidence of significant abundance variations at a given radius in the galaxy. Our results are compared to those of the numerous studies in the literature, and we discuss possible contaminating sources that can inflate abundance dispersion measurements. Importantly, if abundances are derived from a single T

e
measurement and T

e
–T

e
relationships are relied on for inferring the temperature in the unmeasured ionization zone, this can lead to systematic biases that increase the measured dispersion up to 0.11 dex.
Faut-il s’inquiéter du poids élevé des dettes publiques ? Les leçons du cas japonais
Authors: Brender Anton , Pisani Florence 
Published: November 2022

La montée de l’endettement public au Japon inquiète régulièrement. Son rôle dans la gestion de l’équilibre macroéconomique – éviter que la croissance ne soit étouffée par un trop plein d’épargne privé – est plus rarement souligné. Tant que les agents privés continueront de vouloir dépenser moins qu’ils ne gagnent et d’accumuler des créances, espérer voir baisser le poids de l’endettement public dans le PIB est vain. Le gouvernement n’en reste pas moins confronté à un défi majeur : dégager demain des excédents budgétaires si les agents privés décidaient de dépenser plus qu’ils ne gagnent en puisant sur les dépôts qu’ils ont accumulés.

Quelles règles budgétaires pour quelle UEM ?
Authors: Jaillet Pierre , Pfister Christian 
Published: November 2022

Vingt ans après la mise en place de l’UEM, une révision de ses règles budgétaires et, au-delà, de son cadre de coordination économique est à l’ordre du jour. Cet article passe en revue quelques propositions récentes censées aboutir à des règles ou « standards » budgétaires moins complexes, plus flexibles, et tenant mieux compte des spécificités des États membres que les règles actuelles. À rebours, il propose une réforme fondée sur quelques critères simples : variables numériques « opposables » et non manipulables, dont la mise en œuvre soit aisément contrôlable par des autoritéseuropéennes aux prérogatives renforcées. L’objectif de solde structurel, modulable en fonction de la dette des États membres, en deviendrait la variable de commande centrale. Cependant, instaurer de nouvelles règles du jeu communes dans une zone économique de plus en plus hétérogène apparaît plus qu’hypothétique sans un renforcement de la gouvernance communautaire. Aussi les discussions en cours sur le cadre budgétaire ne devraient-elles pas escamoter le chantier plus fondamental de la réforme globale des politiques économiques de l’UEM ? Cela suppose naturellement une volonté politique d’aller vers un modèle moins intergouvernemental et plus fédéral. Classification JEL : H50, H54, H60, H62, H63, H68.
Dette, soutenabilité et responsabilité démocratique européenne
Authors: Creel Jérôme 
Published: November 2022

Les montants élevés de dette publique ravivent les inquiétudes d’une insoutenabilité des finances publiques de certains États membres de l’Union européenne. Les propositions de réforme du cadre budgétaire européen prennent en compte cette dimension, mais peinent à articuler le discours sur les règles, même modifiées, même améliorées, avec leur légitimité démocratique européenne. Celle-ci mérite pourtant d’être discutée pour assurer une meilleure appropriation des règles européennes par les États membres. Classification JEL : E62, H61, H63.
Dissocier la création monétaire des prêts bancaires : retour sur la proposition « 100 % monnaie » des années 1930
Authors: Demeulemeester Samuel 
Published: November 2022

La crise financière mondiale de 2007-2008 a conduit à un renouvellement d’intérêt marqué pour la proposition de réforme « 100 % monnaie », héritée des années 1930, qui vise à dissocier la création monétaire des prêts bancaires en imposant 100 % de réserves sur les dépôts en compte courant. Cette idée de réforme est cependant régulièrement sujette à confusion, étant tantôt assimilée à l’idée d’abolir l’intermédiation bancaire, tantôt à celle d’instaurer un currency board, lorsqu’elle n’est pas confondue avec la proposition plus récente du narrow banking. Pour cette raison, cet article entreprend d’en clarifier le concept et les objectifs, en revisitant les travaux des auteurs de cette proposition dans les années 1930 – Henry Simons, Lauchlin Currie et Irving Fisher notamment. Après un bref rappel historique de l’idée de « 100 % monnaie », nous en présentons les principaux arguments, puis discutons de ses implications pour le système de paiement, l’intermédiation bancaire, et le cadre institutionnel de l’émission monétaire. Nous concluons sur l’importance d’une clarification conceptuelle de cette idée de réforme au regard des débats dont elle continue de faire l’objet.
Creative versus technical work in virtual series
Authors: Twarog Anthony 
Published: November 2022

When a group of fan volunteers created StillFlying.net, a site that hosted Virtual Firefly (VFF), a continuation of the Fox 2002–3 series Firefly, they organized their labor in a way that mirrored actual television production crews, dividing contributors into those with above-the-line creative titles like head writer and those with below-the-line technical titles like art director. By mapping industry hierarchies onto themselves, the VFF community reproduced problematic distinctions between creative and technical work, isolating the site's technical/infrastructural contributors from collaborative support.

Published: November 2022

Abstract
The distribution and diversity of fauna of remote regions, including much of the boreal forest, are incompletely known. We took part in extensive biodiversity surveys in the Far North of Ontario (north of 51° N), Canada from 2009 to 2015. In the family Carabidae Latreille (Coleoptera), we report new records and range extensions for 600 specimens representing 99 species. We documented the first record for Canada of one species, the first records for Ontario of 11 species, and range extensions (> 100 km from the known range) for 70 species. The range extensions were largely in a northwards direction, with a median distance of 650 km and a positive skew in the distribution of these distances. These new records fill an important gap in knowledge of the distribution of this family.
The subgenus Arctotipula Alexander in the genus Tipula Linnaeus (Diptera: Tipulidae) on Wrangel Island, Russia (Chukotka Autonomous Okrug)
Authors: Brodo Fenja , Lantsov Vladimir I. , Khruleva Olga A. 
Published: November 2022

Abstract
Wrangel Island, Russia, because of its geographic position, harsh climate, yet surprising biodiversity, has been geobotanically studied and divided into various subzones. The distributions of the three species of the subgenus Tipula (Arctotipula) (Diptera: Tipulidae) that have been collected on Wrangel Island are related to these subzones. The predominantly Nearctic species, T. (A.) besselsoides Alexander, 1919, is newly recorded for Russia as well as on this island, where it was found to be the most widespread of the three species. The Holarctic species, T. (A.) salicetorum Siebke, 1870, is rarer, being found mostly in the climatically harsh northern and eastern areas of the island. The third species, T. (A.) oklandi Alexander, 1922, which was thought to have been more widespread formerly, is here confirmed only for Russia. It was collected in the warmest part of the island, and the female is illustrated for the first time. An illustrated key to both male and female adults is presented. Distribution maps are provided for all species, and the data on the distribution of oklandi have been adjusted.
A framework of intrapreneurial practices to improve service delivery in municipalities of the O.R. Tambo District Municipality
Authors: Ntoyanto-Tyatyantsi Nonceba , Amandi-Echendu Anthea P. , Mmako Nthabeleng M. 
Published: November 2022

Background: This article examines intrapreneurship principles that can contribute to enhancing the effectiveness of service delivery in the O.R. Tambo District Municipality.Aim: The aim of this research was to investigate whether municipalities practise intrapreneurship and how intrapreneurship drivers may be incorporated into the municipal environment to improve service delivery to surrounding communities.Setting: This study is based in the O.R. Tambo District Municipality, and the target population is middle- and top-level managers from all the municipalities in the district.Methods: The research is situated within the interpretivist paradigm and employed the qualitative method of semi-structured interviews, which were purposively conducted with 12 middle- and top-level managers. Content analysis was used to analyse the data. Municipal documents were also used for triangulation purposes.Results: The empirical findings revealed that policies, laws and regulatory aspects are a hindrance to the development of intrapreneurial practices. The bureaucratic environment that exists is not flexible enough to encourage intrapreneurial conduct among employees. The blurred lines between the administrative and political wings in the municipalities lead to a constricting environment that hinders intrapreneurial practices in the municipalities.Conclusion: A framework for the integration of intrapreneurship drivers to improve service delivery was developed. The article recommends that employees and the community should play a larger role in the planning process so that they can assist to identify best practices and alternate approaches to certain identified issues. The implementation of projects should be left to the administrative managers and staff, and contingency platforms should be introduced to manage transition periods with new replacements.
Preceptor support during the COVID-19 pandemic: Recommendations for continuing development
Authors: Hugo-Van Dyk Lizemari , Nyoni Champion N. , Williams Margaret , Botha Benjamin S. 
Published: November 2022

Background: Mentally fit preceptors may be more capable and flexible in providing students with system, emotional and cognitive support in the clinical learning environment (CLE) in the face of any life-threatening outbreaks. Existing professional development programmes for preceptors emphasise the development of preceptor competence in a normal CLE with minimal focus on their ability to engage with adverse events that challenge their mental health.Objective: The study sought insight from preceptors’ experiences during the coronavirus disease 2019 (COVID-19) pandemic to identify their professional development programme needs while providing support to students during accompaniment.Method: A mixed methods convergent parallel design was used to collect data from 24 preceptors at a nursing education institution (NEI). Eleven preceptors responded to the survey that included the coronavirus disease 2019 (COVID-19) Stress Scale (CSS) and Burnout Assessment Tool (BAT) to collect quantitative data. Semistructured interviews were conducted with five purposively selected preceptors to collect qualitative data regarding their experiences while accompanying students during the COVID-19 pandemic.Results: Subscales within the CSS and BAT instruments were mapped against an existing preceptor support framework. Overall CSS data for each subscale indicated an average score varying from no stress to moderate stress, while BAT data shows that respondents rarely experienced burnout. However, some respondents experienced very high levels of stress and burnout. Qualitative data supplemented results.Conclusion: The COVID-19 pandemic influenced preceptors’ role in supporting students and reflecting that they amended their functioning role. Existing preceptor professional development programmes should be reviewed to ensure that the necessary concepts that foster resilience are integrated to enhance the functional role of preceptors in adversity.Contribution: Existing preceptor professional development programmes should be reviewed to ensure that the necessary concepts that foster resilience are integrated to enhance the functional role of preceptors in adversity.
A conservation organisation’s approach to COVID-19: Lessons learned from Madagascar
Authors: Leeney Ruth H. , Raveloson Herinjaka , Antion Paul , Mohan Vik 
Published: November 2022

Blue Ventures (BV) works holistically with communities in Madagascar, developing transformative approaches to catalyse and sustain locally led marine conservation. In response to the coronavirus disease 2019 (COVID-19) pandemic, BV’s priority was to safeguard the immediate wellbeing and livelihoods of as many communities as possible, recognising that livelihoods are integral to broader well-being. This article describes in detail BV’s health response and the perceptions of BV’s Madagascar team regarding the successes and challenges of this effort. As a result of the combined efforts of BV teams across Madagascar and in the United Kingdom, the existing healthcare services at BV’s sites were maintained, and messages about recognising and dealing with COVID-19 and the importance of vaccination were conveyed to communities that might otherwise not have received comprehensive information. Data were also collected on suspected cases in areas where testing was not available, and outbreaks of suspected COVID-19 cases were managed. Because BV’s teams are embedded within the communities where they work, they maintain strong relationships with communities and conveyed important messages around reducing the spread of COVID-19, not only via activities in response to the pandemic but also through activities for other programmes such as fisheries and livelihoods. Blue Ventures’ holistic approach ensured that the organisation had a multidimensional understanding of the impacts of the pandemic on communities, facilitating the development of more relevant messaging that considered both safety and the need for continued income-generating activities. Staff felt that an effective public health response was facilitated by strong in-country partnerships and BV’s long-standing presence in communities.Contribution: The challenges in responding to the pandemic and in implementing and maintaining effective behaviour change are discussed. Although not an objective study of the effectiveness of the response or a comparison with other approaches, the lessons learned from this process are shared in the hope that they may inform responses to future shocks in low-income countries.

Published: November 2022

The study sought to examine the impact of coronavirus disease 2019 on the socioeconomic livelihoods of rural communities by focusing on the Good Hope community under Mbashe Municipality. A qualitative research methodology was employed through in-depth interviews and focus group discussions. The study sought to examine the impact and survival strategies employed by the Good Hope community with the outbreak of the coronavirus, which has widely affected the world since 2019. The study further aimed to examine the role of the South African government in assisting rural communities since the outbreak of the coronavirus.Contribution: The study’s findings highlight the lack of proper intervention strategies employed by the government in assisting rural communities. Communities including Good Hope have been hard hit by the pandemic and continue to suffer under the implemented lockdown regulations imposed by all governments globally.

Background: Early classroom communication supports are critical in influencing oral language development and emergent literacy skills. It is both support from peers and adults, as well as the environment that impacts the quality and efficacy of language learning. Schools in particular play a key role in communication development, which will be further explored in this article.Objectives: To describe how communication was being supported in the classroom by teachers in the areas of language-learning environment (LLE), language-learning interactions (LLIs) and language-learning opportunities (LLOs) to focus on classroom communication supports to strengthen literacy outcomes for Grade R learners.Method: A cross-sectional descriptive survey of classrooms was conducted using a structured observation method in 136 classrooms. The Communication Supporting Classroom Observation Tool was used to make 223 observations across classrooms of LLE (19 items), LLI (20 items) and LLO (5 items). A descriptive analysis of frequency of occurrence of items was conducted for each domain.Results: Language-learning environment had more frequently occurring observations, with 12 out of 19 items being observed with a frequency of occurrence greater than 65%, indicating that the environment had adequate basic resources (e.g. good light). Language-learning interactions scores indicated that 3 out of 20 items were observed frequently, while 17 out of 20 items were observed less frequently (56.5%), including interactive strategies (e.g. turn-taking). Language Learning Opportunities scores indicated that teacher-led behaviours (e.g. including children in small group activities) were infrequently observed on all items.Conclusion: While the physical environment was generally supportive, the behaviours in the interactive domains of LLI and LLO were observed less frequently. There is potential for speech–language therapists to work collaboratively with teachers to develop communication supporting classrooms as a critical primary-level intervention for language-literacy learning.
A mixed-method study about performance-enhancing agents
Authors: Othman Amna M. , Saber-Ayad Maha , Alzubaidi Hamzah , Hamid Qutayba , Sulaiman Nabil 
Published: November 2022

Background:
This mixed-method study explored knowledge, perceptions, and practices of performance-enhancing agents (PEAs) among university students, the public, and sports club stakeholders in the United Arab Emirates (UAE).

Methods
A mixed-method study was conducted; a total of 353 participants (289 students and 64 members of the public) completed the web-based survey, and 34 sports club stakeholders and 6 community pharmacists were interviewed.

Results
These showed that most sports club stakeholders were unfamiliar with the prohibited substances in the UAE. Moreover, some interviewees were unwilling to learn more about PEAs. Out of the participants, 72% of the students and 78% of the public had positive perceptions about prohibiting certain and harmful types of PEAs in sports and reported unfavorable views toward doping agents’ users. Regarding the personal experience with banned substance(s), 5.7% of the students and 3.2% of the public reported using them. There was a clear diversity among sports club stakeholders regarding the problem of doping in the UAE.

Conclusion
There were gaps in knowledge about World Anti-Doping Agency’s role. Participants have the impression that doping is prevalent among bodybuilders, non-athletes, and young individuals in private gyms. In conclusion, there is a significant gap in knowledge of doping among university students and sports club stakeholders, highlighting the need for tailored education programs specifically designed for sports club stakeholders, and students aiming at reducing PEAs use.
