Wi-Fi And Bluetooth Contact Tracing Without User Intervention
Authors: Yuen Brosnan , Bie Yifeng , Cairns Duncan , Harper Geoffrey , Xu Jason , Chang Charles , Dong Xiaodai , Lu Tao
Published: March 2022

A custom Wi-Fi and Bluetooth contact tracing system is created to find detailed paths of infected individuals without any user intervention. The system tracks smartphones, but it does not require smartphone applications, connecting to the routers, or any other extraneous devices on the users. A custom Turtlebot3 is used for site surveying, where it simulates mobile device movement and packet transmission. Transmit power, receive power, and round trip time are collected by a custom ESP32C3 router. MAC randomization is defeated to identify unique smartphones. Subsequently, the wireless parameters above are converted to signal path loss and time of flight. Bidirectional long short term memory takes the wireless parameters and predicts the detailed paths of the users within 1 m. Public health authorities can use the contact tracing website to find the detailed paths of the suspected cases using the smartphone models and initial positions of confirm cases. The system can also track indirect contact transmissions originating from surfaces and droplets due to having absolute positions of users.

Published: March 2022

The experiment was conducted during 2019 and 2020 growing seasons at wondogenet and wondo. Six potato varieties were tested using randomized complete block design with three replications using mother-baby trial approach. All necessarily data were collected from the mother trial and analyzed using SAS software and SPSS. The combined analysis of variance showed the presence of significant differences (p≤0.05) among tested varieties for plant height, tuber diameter and tuber yield per hectare. The highest tuber weight per plant was harvested from Gudane variety (1.68) which was statistically similar with Jalene (1.49) variety but Dagim variety was gave the lowest (0.30) which was statistically similar with Gera (0.75) variety. Gudane variety gave the highest tuber yield per hectare (33.67) which had no statistically difference with the yield obtained from Jalene variety (30.67) while the lowest (14.05) was recorded from Dagim variety. The participated farmers have given a rank for the traits used for selection and evaluated the varieties using their own selection criterias. As a result, based on their preferences Gudane, Jalene and Guassa varieties were selected as the first, second and third choices. Therefore, scaling up of these selected varieties should be done in the study area and areas with similar agroecologies so that producers can able to access the variety to the farmers resulted in overcoming food insecurity.

Published: March 2022

This study examined the effect of corporate governance on selected insurance companies using panel data which span from 2016 to 2020 five years for each of the selected insurance companies. This research statistically pinpoint the impact of corporate governance on the financial performance of insurance companies in Nigeria using the most recent data on shareholders controlling interest ratio. The researcher subjected the data to statistical examinations using the panel least square regression and the Granger causality test and the findings revealed that, in line with expectation, board size positively predicted return on assets in insurance companies. This prediction was found to be insignificant however. The study recommends that Insurance companies should possess a board size large enough to encompass individuals of diverse level of knowledge and expertise. This would make the board competent enough to make sound decisions in diverse fields. Compensation of directors should be tailored to the level of the financial performance of the insurance company. This could be done by allotting bonuses and benefits based on profitability.

Authors: Nyalazi Jessie I. M. , Muma Kangwa I. M. , Kasongole David
Published: March 2022

This is a case report of post intravitreal injection endophthalmitis encountered at the University Teaching Hospitals–Eye Hospital in Lusaka, Zambia. Endophthalmitis is a clinical diagnosis made when intraocular inflammation involving both the anterior and posterior chambers is attributable to bacterial or fungal infection. Post injection endophthalmitis is a dreaded complication that occurs following intraocular surgery or procedures such as intravitreal administration of anti-vascular endothelial growth factors or corticosteroids. We attended to a rare case of bilateral post intravitreal injection endophthalmitis in a 51- year- old female patient who presented with bilateral severe pain and acute visual loss in both eyes following intravitreal injection of Avastin (bevacizumab) the previous day. On examination, there was severely decreased visual acuity from 6/36 right eye and 6/60 left eye to hand movement in both eyes. There was also corneal haziness, fibrin in the anterior chambers, hypopyon and vitreous cells in both eyes. A clinical diagnosis of bilateral post-injection endophthalmitis was made. There was immediate administration of intravitreal antibiotics of Vancomycin 1.0mg/0.1mL and Ceftazidime 2.25mg/0.1mL with intravitreal Dexamethasone 0.4mg/0.1ml stat dose and systemic ciprofloxacin 750mg 12 hourly for 7 days. Due to prompt diagnosis and treatment vision recovery was excellent in both eyes and both eyes were preserved.

Accusers as Adjudicators in Agency Enforcement Proceedings
Authors: Vollmer Andrew
Published: March 2022

Largely because of the Supreme Court’s 1975 decision in Withrow v. Larkin, the accepted view for decades has been that a federal administrative agency does not violate the Due Process Clause by combining the functions of investigating, charging, and then resolving allegations that a person violated the law. Many federal agencies have this structure, such as the Securities and Exchange Commission (SEC) and the Federal Trade Commission.

In 2016, the Supreme Court decided Williams v. Pennsylvania, a judicial disqualification case that, without addressing administrative agencies, nonetheless raises a substantial question about one aspect of the combination of functions at agencies. The Court held that due process prevented a judge from sitting in a case in which he had participated as district attorney years earlier. The operative principle for the decision was that “the Court has determined that an unconstitutional potential for bias exists when the same person serves as both accuser and adjudicator in a case.”

This Article concludes that the reasoning of Williams should supersede Withrow on the need to disqualify a specific commissioner or agency head from participating in a particular adjudication if the agency official played a meaningful role, such as voting to approve enforcement charges, in the process leading to the agency’s initiation of proceedings against the defendant. Voting to approve enforcement charges would be a meaningful role. The due process cases do not permit a compromise on the high standards of impartiality demanded of a final agency decision maker in an adjudication to determine whether a private party committed a violation of law.

That reading of Williams threatens to unsettle standard practices at various agencies, but a closer look at the procedures of the SEC shows that it would be able to accommodate the rule in Williams yet retain the combination of charging and adjudicating at the Commission level. Because of turnover of Commissioners and quorum rules, the SEC could continue to have the agency leaders bring enforcement cases and review nearly all administrative law judge decisions while disqualifying individual Commissioners under Williams when necessary.

The development of digital technologies in the economy requires the transformation of business processes at the level of organizations focused on a strategic perspective. In the digital economy, obtaining strategic competitive advantages is associated with the formation and development of the potential of organizations. The use of digital technologies leads to the introduction of new methods, tools and services that require infrastructural changes in organizations and contribute to the creation of new products (works, services) that increase the competitiveness and financial stability of organizations. The process of digital transformation of the economy is multi-stage, and each stage has goals, objectives and evaluation criteria. The first step towards the economy digital transformation is to assess the digital potential, digital maturity and readiness of organizations.

The originality lies in the development of theoretical and methodological foundations for assessing the level of the economy digital transformation and in the development of promising areas.

The author's definition of the digital potential of an organization is given as the ability to perform activities to create, introduce, develop and implement information and communication technologies in the context of the transformation of business processes, business models in order to ensure strategic competitive advantages in the markets, financial stability and performance.

The assessment methodology is proposed and the following groups of estimated private indicators have been identified: digital transformation of the organization, intellectual capital, customer interaction: service quality and customer satisfaction, online sales, business environment.

Determined that digital transformation, as the technical and technological core of the digital economy, through the introduction of digital technologies,

transforms the structure of the added value of the product by including the digital and intellectual component in the chain of its creation.

The study uses the latest provisions of the theory of social development, systemology, economic information theory, institutional and neo-institutional economic theory, strategic, industrial and innovation management. Development is defined as the archetype of entrepreneurship and the most important category of socio-economic life. The study established a link between socio-economic and innovative development of enterprises and other socio-economic systems. The directions of business that suffered and developed during the corona crisis were analyzed and an assessment of its innovation was provided. The mutual influence of socio-economic and innovative development of enterprises is proved. Peculiarities of development of innovation activity in the conditions of imperfect branch structure of economy are substantiated. It was emphasized that Ukrainian enterprises should adapt the market and business experience of the world is leading countries, improve infrastructure and the institutional environment, increase human capital, knowledge and technology. The direct vector of innovative development for Ukrainian entrepreneurship is Ukraine's integration into the EU: for enterprises and educational and research institutions – into the European Scientific Area, infusion into clusters specializing in «aerospace industry» – south-eastern Poland, «toolmaking» – Slovenia, «automotive industry» – Slovakia. Emphasis is placed on the expediency of applying the world practice of creating new targeted tools to support the economic and innovative development of entrepreneurship on the basis of medium-term and long-term programs and strategies.
Economic analysis based on indicators in the company
Authors: Ślusarczyk Maciej
Published: March 2022

The aim of the article is to show suitable and universal methods of economic analysis using the analysis of economic indicators in a combination of research methodology, which focuses on the micro and macro environment of an enterprise embedded in a vibrating, uncertain and constantly changing environment.

The article shows the validity of the centrifugal and centripetal environment analysis method, which results in analytical data in the context of primary measurement and analytical data on the basis of which the analysis of financial ratios can begin.

The author presented the validity of the financial result based on the economic analysis formulas for which specific values were adopted. As a result of combining the research methodology and economic analysis, a measurement and analytical tool was obtained, which forms the basis for strategic action and can be used in in-depth analysis, in which the research and analysis can be subjected to a more detailed examination and the results narrowed down or expanded to include the aspects most relevant to the company.

The result of this analysis is an article that proposes a duality of both methods in terms of analysis and research. Due to the uncertain and oscillating environment, these methods can be assumed to be effective. The validity of the combination of these methods and economic indicators is extremely important and should be analysed in depth, and working with their results will provide a clear analytical picture available at every stage of the company's development.
Potential benefits and risks from Poland’s accession to the euro area
Authors: Dudzik Iwona , Brukwicka Irena
Published: March 2022

This paper reviews the selected issues related to the potential benefits and risks of Poland’s accession to the euro area.  Poland has joined the European Union in 2004. Being a member of the Economic and Monetary Union, Poland was obliged to adopt the euro as its currency, but the date of the above currency introduction was not specified. Poland’s joining the euro area is often discussed in political and economic debates. Such debates benefit primarily from politics and ideology, and the economic issues, associating possible benefits and risks resulting from Poland’s accession to the euro area.  The opponents of the common currency deal with issues related to the financial crisis in the territory of the euro zone counties. According to the study conducted in 2010 by the Public Opinion Research Center, it was observed that the number of Poles supporting Poland’s accession to the euro area was decreasing. The survey conducted by CBOS in 2017 showed that the number of respondents who were against Poland’s accession to the euro area was 72%. The purpose of this paper is to analyze the basic benefits and costs that result from the adoption of the common currency by Poland.
The Accretion Process in the DQ Tau Binary System
Authors: Fiorellino E. , Park S. , Kóspál Á. , Ábrahám P.
Published: March 2022

Mass accretion from the circumstellar disk onto the protostar is a fundamental process during star formation. Measuring the mass accretion rate is particularly challenging for stars belonging to binary systems, because it is often difficult to discriminate which component is accreting. DQ Tau is an almost equal-mass spectroscopic binary system where the components orbit each other every 15.8 days. The system is known to display pulsed accretion, i.e., the periodic modulation of the accretion by the components on eccentric orbit. We present multi-epoch ESO/Very Large Telescope X-Shooter observations of DQ Tau, with the aim of determining which component of this system is the main accreting source. We use the absorption lines in the spectra to determine the radial velocity of the two components, and measure the continuum veiling as a function of wavelength and time. We fit the observed spectra with nonaccreting templates to correct for the photospheric and chromospheric contribution. In the corrected spectra, we study in detail the profiles of the emission lines and calculate mass accretion rates for the system as a function of orbital phase. In accordance with previous findings, we detect elevated accretion close to periastron. We measure the accretion rate as varying between 10−8.5 and 10−7.3
M
⊙ yr−1. The emission line profiles suggest that both stars are actively accreting, and the dominant accretor is not always the same component, varying in a few orbits.

Published: March 2022

We report results of observations of the GGD 12-15 region, where cluster formation is actively taking place, using various molecular emission lines. The C18O (J = 1−0) emission line reveals a massive clump in the region with a mass of ∼2800 M
⊙ distributed over ∼2 pc. The distribution of the C18O (J = 3−2) emission is similar to that of a star cluster forming therein, with an elliptical shape of ∼1 pc in size. A bipolar molecular outflow driven by IRS 9Mc, a constituent star of the cluster, is blowing in the direction perpendicular to the elongated C18O (J = 3−2) distribution, covering the entire clump. There is a massive core with a radius of 0.3 pc and a mass of 530 M
⊙ in the center of the clump. There are two velocity components around the core, which are prominent in a position–velocity (PV) diagram along the major axis of the clump. In addition, a PV diagram along the minor axis of the clump, which is parallel to the outflow, shows a velocity gradient opposite to that of the outflow. The velocity structure strongly indicates the infalling motion of the clump. Comparison of the observational data with a simple model of infalling oblate clumps indicates that the clump is undergoing gravitational contraction with rotation.
Dust Dynamics in Transitional Disks: Clumping and Disk Recession
Authors: Bi 毕 Jiaqing 嘉擎 , Fung 馮 Jeffrey 澤之
Published: March 2022

The role of radiation pressure in dust migration and the opening of inner cavities in transitional disks is revisited in this paper. Dust dynamics including radiation pressure is often studied in axisymmetric models, but in this work, we show that highly non-axisymmetric features can arise from an instability at the inner disk edge. Dust grains clump into high density features there, allowing radiation to leak around them and penetrate deeper into the disk, changing the course of dust migration. Our proof-of-concept, two-dimensional, vertically averaged simulations show that the combination of radiation pressure, shadowing, and gas drag can produce a net outward migration, or recession, of the dust component of the disk. The recession speed of the inner disk edge is on the order of 10−5 times Keplerian speed in our parameter space, which is faster than the background viscous flow, assuming a Shakura–Sunyaev viscosity α ≲ 10−3. This speed, if sustained over the lifetime of the disk, can result in a dust cavity as large as tens of astronomical units.
Pearls on a String: Numerous Stellar Clusters Strung Along the Same Orbit
Authors: Coronado Johanna , Fürnkranz Verena , Rix Hans-Walter
Published: March 2022

Stars originate from the dense interstellar medium, which exhibits filamentary structure to scales of ∼1 kpc in galaxies like our Milky Way. We explore quantitatively how much resulting large-scale correlation there is among different stellar clusters and associations in orbit-phase space, characterized here by actions and angles. As a starting point, we identified 55 prominent stellar overdensities in the 6D space of orbit (actions) and orbit-phase (angles) among the ∼2.8 million stars with radial velocities from Gaia EDR3 and with d ≤ 800 pc. We then explored the orbit-phase distribution of all sample stars in the same orbit patch as any one of these 55 overdensities. We find that very commonly numerous other distinct orbit-phase overdensities exist along these same orbits, like pearls on a string. These “pearls” range from known stellar clusters to loose, unrecognized associations. Among orbit patches defined by one initial orbit-phase overdensity, 50% contain at least 8 additional orbit-phase pearls of 10 cataloged members; 20% of them contain 20 additional pearls. This is in contrast to matching orbit patches sampled from a smooth mock catalog, or offset nearby orbit patches, where there are only 2 (or 5, respectively) comparable pearls. Our findings quantify for the first time how common it is for star clusters and associations to form at distinct orbit-phases of nearly the same orbit. This may eventually offer a new way to probe the 6D orbit structure of the filamentary interstellar medium.

We present results from Atacama Large Millimeter/submillimeter Array (ALMA) 1.2 mm continuum observations of a sample of 27 star-forming galaxies at z = 2.1–2.5 from the MOSFIRE Deep Evolution Field survey with metallicity and star formation rate measurements from optical emission lines. Using stacks of Spitzer, Herschel, and ALMA photometry (rest frame ∼8–400 μm), we examine the infrared (IR) spectral energy distributions (SED) of z ∼ 2.3 subsolar-metallicity (∼0.5 Z
⊙) luminous infrared galaxies (LIRGs). We find that the data agree well with an average template of higher-luminosity local low-metallicity dwarf galaxies (reduced χ
2 = 1.8). When compared with the commonly used templates for solar-metallicity local galaxies or high-redshift LIRGs and ultraluminous IR galaxies, even in the most favorable case (with reduced χ
2 = 2.8), the templates are rejected at >98% confidence. The broader and hotter IR SED of both the local dwarfs and high-redshift subsolar-metallicity galaxies may result from different grain properties or a harder/more intense ionizing radiation field that increases the dust temperature. The obscured star formation rate (SFR) indicated by the far-IR emission of the subsolar-metallicity galaxies is only ∼60% of the total SFR, considerably lower than that of the local LIRGs with ∼96%–97% obscured fractions. Due to the evolving IR SED shape, the local LIRG templates fit to mid-IR data overestimate the Rayleigh–Jeans tail measurements by a factor of 2–20. These templates underestimate IR luminosities if fit to the observed ALMA fluxes by >0.4 dex. At a given stellar mass or metallicity, dust masses at z ∼ 2.3 are an order of magnitude higher than z ∼ 0. Given the predicted molecular gas fractions, the observed z ∼ 2.3 dust-to-stellar mass ratios suggest lower dust-to-molecular gas masses than in local galaxies with similar metallicities.

Published: March 2022

To understand the formation of the Milky Way’s prominent bar it is important to know whether stars in the bar differ in the chemical element composition of their birth material as compared to disk stars. This requires stellar abundance measurements for large samples across the Milky Way’s body. Such samples, e.g., luminous red giant stars observed by the Sloan Digital Sky Survey’s APOGEE survey, will inevitably span a range of stellar parameters; as a consequence, both modeling imperfections and stellar evolution may preclude consistent and precise estimates of their chemical composition at a level of purported bar signatures, which has left current analyses of a chemically distinct bar inconclusive. Here, we develop a new self-calibration approach to eliminate both modeling and astrophysical abundance systematics among red giant branch (RGB) stars of different luminosities (and hence surface gravity

). We apply our method to 48,853 luminous APOGEE Data Release 16 RGB stars to construct spatial abundance maps of 20 chemical elements near the Milky Way’s mid-plane, covering galactocentric radii of 0 kpc < R
GC < 20 kpc. Our results indicate that there are no abundance variations whose geometry matches that of the bar, and that the mean abundance gradients vary smoothly and monotonically with galactocentric radius. We confirm that the high-α disk is chemically homogeneous, without spatial gradients. Furthermore, we present the most precise [Fe/H] versus R
GC gradient to date with a slope of − 0.057 ±0.001 dex kpc−1 out to approximately 15 kpc.
In Situ Measurement of the Energy Fraction in Suprathermal and Energetic Particles at ACE, Wind, and PSP Interplanetary Shocks
Authors: David Liam , Fraschetti Federico , Giacalone Joe , Wimmer-Schweingruber Robert F. , Berger Lars , Lario David
Published: March 2022

The acceleration of charged particles by interplanetary shocks (IPs) can drain a nonnegligible fraction of the plasma pressure. In this study, we have selected 17 IPs observed in situ at 1 au by the Advanced Composition Explorer and the Wind spacecraft, and 1 shock at 0.8 au observed by Parker Solar Probe. We have calculated the time-dependent partial pressure of suprathermal and energetic particles (smaller and greater than 50 keV for protons and 30 keV for electrons, respectively) in both the upstream and downstream regions. The particle fluxes were averaged for 1 hr before and 1 hr after the shock time to remove short timescale effects. Using the MHD Rankine–Hugoniot jump conditions, we find that the fraction of the total upstream energy flux transferred to suprathermal and energetic downstream particles is typically ≲16%, in agreement with previous observations and simulations. Notably, by accounting for errors on all measured shock parameters, we have found that for any given fast magnetosonic Mach number, M

f
< 7, the angle between the shock normal and average upstream magnetic field, θ
Bn, is not correlated with the energetic particle pressure; in particular, the partial pressure of energized particles does not decrease for θ
Bn ≳ 45°. The downstream electron-to-proton energy ratio in the range ≳ 140 eV for electrons and ≳ 70 keV for protons exceeds the expected ∼1% and nears equipartition (>0.1) for the Wind events.
Full-sky, Arcminute-scale, 3D Models of Galactic Microwave Foreground Dust Emission Based on Filaments
Authors: Hervías-Caimapo Carlos , Huffenberger Kevin M.
Published: March 2022

We present the DustFilaments code, a full-sky model for the millimeter Galactic emission of thermal dust. Our model, composed of millions of filaments that are imperfectly aligned with the magnetic field, is able to reproduce the main features of the dust angular power spectra at 353 GHz as measured by the Planck mission. Our model is made up of a population of filaments with sizes following a Pareto distribution

, with an axis ratio between short and long semiaxes ϵ ∼ 0.16 and an angle of magnetic field misalignment with a dispersion rms(θ
LH) = 10°. On large scales, our model follows a Planck-based template. On small scales, our model produces spectra that behave like power laws up to ℓ ∼ 4000 or smaller scales by considering even smaller filaments, limited only by computing power. We can produce any number of Monte Carlo realizations of small-scale Galactic dust. Our model will allow tests of how the small-scale non-Gaussianity affects CMB weak lensing and the consequences for the measurement of primordial gravitational waves or relativistic light relic species. Our model also can generate frequency decorrelation on the modified blackbody spectrum of dust and is freely adjustable to different levels of decorrelation. This can be used to test the performance of component separation methods and the impact of frequency spectrum residuals on primordial B-mode surveys. The filament density we paint in the sky is also able to reproduce the general level of non-Gaussianities measured by Minkowski functionals in the Planck 353 GHz channel map.
Association Between Lymphocyte Level and Severity of Coronavirus Disease 2019 Patients: A Cross-sectional Study in Indonesia
Authors: Buchari Buchari , Andayani Hafni , Putri Nadia Ayunda
Published: March 2022

BACKGROUND: Coronavirus disease 2019 (COVID-19) pandemic has caused significant health problems globally. COVID-19 should be considered a systemic disease since it involves multiple systems, including the hematopoietic system and the immune system.

AIM: This study sought to determine the relationship between the lymphocyte levels and the severity of COVID-19 patients in Indonesia.

METHODS: A cross-sectional study was conducted among COVID-19 patients at Dr. Zainoel Abidin Hospital Banda Aceh Indonesia from August 27, to September 20, 2021. The subjects were recruited using consecutive sampling method and the data were obtained at their admission to the hospital. Chi-squared test was used to assess the association between lymphocyte levels and the severity of patients.

RESULTS: A total of 280 COVID-19 patients included of which 56.9% (91/160) of the patients with moderate severity, 76.1% (51/67) with a severe condition, and 84.9% (45/53) with critical severity had lymphopenia. There were no patients with lymphocytosis found in this study (0%). The Chi-squared test suggested that the lymphocyte level was significant associated with the severity of COVID-19 patients with p < 0.001.

CONCLUSION: Our study suggests that the lower the lymphocyte level, the higher the severity of COVID-19 patients. The level of lymphocyte is therefore potentially to be used as predictor for the disease severity and needs to be monitored regularly in COVID-19 patients.

Published: March 2022

Nous tenterons de montrer que le symptôme hallucinatoire à l’adolescence pourrait être considéré, dans certains cas, et au-delà du binarisme névrose-psychose, comme une tentative de symbolisation, participant du travail de subjectivation donnant accès à la différence sexuée. Certaines manifestations hallucinatoires à cet âge pourraient, en effet, être entendues à la fois comme la trace d’un défaut partiel de symbolisation du corps mais aussi comme la tentative de symbolisation des éprouvés infantiles, remaniés dans l’après-coup pubertaire, du fait de la diminution de la force du refoulement et de la force du surmoi, de même que du retour du réel de l’excès pulsionnel.

Sans banaliser ses possibles effets négatifs, il s’agit d’appréhender la pornographie à l’aune de sa fonction au regard du réel sexuel. En tant que dispositif, la pornographie apparaît comme pièce de théâtre grotesque qui exacerbe les traits structuraux de la sexualité. L’inquiétude politique quant à ses effets peut recouvrir un point de vue normatif à propos de la sexualité désormais « médicalisée ».

L’accompagnement des résidents en foyer d’accueil médicalisé, alors que la crise liée à la Covid-19 s’étend, est mis à rude épreuve. Si, au départ, les équipes éducatives ont été bousculées par la médicalisation de l’accompagnement et par l’arrivée de professionnels dits de renfort, la collaboration avec ceux-ci et avec l’équipe mobile de soins palliatifs a pris ensuite sens. Elle s’est révélée soutenante et enrichissante. Tous ces professionnels ont coopéré, mutualisé leurs connaissances et leurs savoir-faire et agi ensemble.

Introduction : L’épidémie de COVID a présenté un défi majeur pour les acteurs et les organisations des soins primaires en France. L’objectif de ce travail réalisé par le réseau de recherche ACCORD, associant praticiens et chercheurs, est de décrire et d’analyser en interprofessionnalité les adaptations et organisations précoces des acteurs des soins primaires durant le premier confinement. Méthodes : Ce travail confronte du matériel quantitatif et qualitatif. Les données quantitatives résultent d’une exploitation croisée des six enquêtes en ligne réalisées par le réseau ACCORD, entre mars et mai 2020, auprès des médecins généralistes, sages-femmes et structures pluriprofessionnelles en France. Ces données ont été enrichies d’échanges collectifs pluriprofessionnels et pluridisciplinaires, conduits en groupes focaux lors d’un séminaire dématérialisé. Résultats : Durant la période considérée, une baisse importante de l’activité en soins primaires a été constatée. Les acteurs ont été nombreux à adapter leurs organisations pour concilier risque épidémique et maintien de l’accès et de la continuité des soins. Les sources d’information utilisées par les professionnels se sont avérées très variables. La crise a révélé des réseaux d’échange et de collaboration importants au niveau des territoires. Conclusion : Face à la crise sanitaire, les acteurs des soins primaires ont adapté leurs organisations et leurs pratiques de façon précoce et diversifiée, soulignant l’importance des organisations préexistantes et des collaborations à l’échelon territorial.

Après la déclaration d’urgence de santé publique d’importance internationale, les hôpitaux sont devenus une référence dans la réponse à la pandémie. Il est donc important d’évaluer la capacité à répondre à la pandémie de COVID-19 parmi les professionnels de la santé d’un hôpital de référence à Pernambuco, dans le nord-est du Brésil. Cette étude traite d’un recherche évaluative qualitative, de type étude de cas. Trois méthodes ont été utilisées pour identifier les événements critiques : entretien avec 18 professionnels de la santé qui avaient travaillé en « première ligne » de soins pour les personnes atteintes de la COVID-19, observation directe dans les secteurs de cet hôpital et analyse documentaire. Les entretiens ont été transcrits et analysés à l’aide du logiciel MaxQDA Analytics pro 2020 ® , en utilisant la Théorie Acteur-Réseau et pour interpréter les événements critiques, les catégories de résilience : absorption, adaptation et transformation. Il a été constaté que la capacité de réponse des professionnels était influencée par cinq événements critiques : l’arrivée des cas, de nouvelles façons de mettre le patient en relation avec son réseau de soutien social, l’impact social et personnel sur la vie quotidienne des professionnels, le manque d’équipement essentiel et tests de confirmation, enfin la pénurie et la maladie des professionnels. L’étude montre que dans les expériences quotidiennes, la capacité de réponse des professionnels a conduit à un processus d’adaptation prioritaire qui peut accélérer des changements importants dans le système de santé.
Gérer la crise de la première vague de COVID-19 : retour d’expérience d’une agence régionale de santé

La crise de la COVID-19 a bouleversé l’organisation sanitaire en France, particulièrement dans son administration. Or, la gestion de crise par les agences régionales de santé (ARS) est insuffisamment étudiée. Basée sur un exercice de retour d’expérience (Retex) interne via une méthode qualitative de croisement de sources documentaires et d’entretiens semi-dirigés, cette étude rend compte de la gestion régionale de la crise COVID-19 depuis une organisation administrative : ses dynamiques temporelle et organisationnelle, le rôle exercé par cette autorité publique et les stratégies mobilisées, en interaction avec les acteurs à différentes échelles. Entre janvier et juin 2020, la gestion de la COVID-19 a été marquée par la perturbation subite des repères, de l’agenda habituel des priorités et par une installation inhabituelle dans la durée. En situation d’adaptation permanente, l’ARS étudiée (Nouvelle-Aquitaine) a mis en place une organisation ad hoc de gestion de crise. Elle s’est positionnée, tel un maillon majeur du dispositif national de gestion de crise, en interaction avec divers acteurs, avec un éventail d’instruments d’action publique. Cette étude met en discussion les données recueillies sur une gestion de crise sanitaire par une ARS, démontrant l’intérêt de Retex de crise, à visées interne pour l’administration et heuristiques, et questionne savoirs et maîtrises habituels.

L’irruption de la pandémie liée à la COVID-19 s’est traduite par des retombées majeures sur les systèmes de soins. En parallèle, la crise sanitaire a occasionné une surabondance d’information. L’accès à une information vérifiée et actualisée revêt un caractère crucial pour la compréhension de l’épidémie et des mesures de prévention par les professionnels et la population. Dans ce contexte, le Comité régional d’éducation pour la santé (CRES) Provence-Alpes-Côte d’Azur, centre de ressources en promotion et éducation pour la santé, a pleinement joué son rôle d’acteur de santé publique en s’engageant dans une démarche de transfert de connaissances avec la création de trois outils : une lettre de veille, une série d’enregistrements audio et une formation. Il a aussi transformé ses activités habituelles par le recours au numérique. Cet article décrit la nécessaire adaptation à une situation inédite, tant par la création rapide d’activités nouvelles que l’adaptation d’activités traditionnelles à un contexte complexe. Il montre, également, en quoi ces activités sont pertinentes et ont répondu à une demande des professionnels. Les résultats des évaluations témoignent de la pertinence des outils mis à la disposition des professionnels : leur besoin d’accéder à une information claire et validée scientifiquement a été assouvi. Le CRES s’est positionné comme un acteur essentiel, depuis le début de la crise, en facilitant l’accès à la connaissance. De nouveaux besoins liés à l’épidémie sont aujourd’hui identifiés et constituent des perspectives concrètes pour le CRES.

Older adults face several challenges when accessing specialist care. Advanced practice nurses (APNs) can perform an important role in primary care for older adults, particularly when bolstered with digital tools. In the current study, we conducted a multiple case study of electronic consultations (eConsults) involving APNs to assess how these practitioners use the service to improve access to care. All eConsults submitted by or to an APN in 2019 on behalf of patients aged ≥65 years were reviewed to identify examples from six settings representative of the range of advanced nursing practices. For each setting, a final case was chosen using an iterative process and stratified by specialty and type of advice. Included cases were assessed using a conceptual framework for health care access. Selected cases illustrate how APNs can be effective users of eConsults in a diversity of health care settings. The framework allowed for an in-depth study of access over the range of interactions that take place among patients, caregivers, providers, and the health care system. [

Learning Lessons From International Education in Crisis Research
Authors: Fairchild Nikki , Emerson Ann , Hamilton Sukhbinder
Published: March 2022

This chapter will apply lessons learned from the humanitarian sector's decades of international education in crisis research to the UK's real-time phased return to Early Childhood Education and Care (ECEC) settings following the COVID-19 lockdown. ECEC Teachers contribute to strong early attachments and stability of routines that are key for supporting a young child's personal, social, and emotional well-being. Although these principles are normally embedded in most ECEC practice, during the time of COVID-19 new ways of relating to others due to social distancing measures may upset these routines, attachments, and social interactions that are critical for young children. The authors apply lessons learned from decades of international education in times of crisis. Drawing on intersectional and postcolonial approaches, the authors consider how scholars and organizations from the Global South can bring a new dimension to ECEC practice. This provides policy makers and ECEC Teachers the opportunity to develop their skill sets to support transitions back to settings post lockdown.
