Continuous, risk-based, consultation peer review in out-of-hours general practice: a qualitative interview study of the benefits and limitations
Authors: Bennett-Britton Ian , Banks Jonathan , Carson-Stevens Andrew , Salisbury Chris 
Published: May 2021

BackgroundSystems to detect and minimise unwarranted variation in clinician practice are crucial to ensure increasingly multidisciplinary healthcare workforces are supported to practise to their full potential. Such systems are limited in English general practice settings, with implications for the efficiency and safety of care.AimTo evaluate the benefits and limitations of a continuous, risk-based, consultation peer-review system used for 10 years by an out-of-hours general practice service in Bristol, UK.Design and settingA qualitative study in South West England.MethodSemi-structured interviews with intervention users (clinicians, peer reviewers, and clinical management), analysed by inductive thematic analysis and integrated into a programme theory.ResultsTwenty clinicians were interviewed between September 2018 and January 2019. Interviewees indicated that the intervention supported clinician learning through improved peer feedback, highlighting learning needs and validating practice. It was compared favourably with existing structures of ensuring clinician competence, supporting standardisation of supervision, clinical governance, and learning culture. These benefits were potentially limited by intervention factors such as differential feedback quality between clinician groups, the efficiency of methods to identify learning needs, and limitations of assessments based on written clinical notes. Contextual factors such as clinician experience, motivation, and organisational learning culture influenced the perception of the intervention as a support or a stressor.ConclusionThe findings demonstrate the potential of continuous, risk-based, consultation peer review to support clinicians in an increasingly multidisciplinary general practice workforce to efficiently and safely practise to their full potential. The programme theory provides a theoretical basis to maximise the benefits and accommodate the potential limitations of this methodology
Polskie media wobec Ukrainy. Przyczynek do dyskusji
Authors: Szeptycki Andrzej 
Published: May 2021

Polish media has played an active role in the policy towards Ukraine, particularly from the outbreak of the Revolution of Dignity and war with Russia, but this subject has not received in-depth academic treatment. The author describes the discourse of Polish mass media on the subject of Ukraine, using selected television stations and newspapers as examples. The most important television stations (TVP, TVN, Polsat) do not present a uniform image of Ukraine, and their discourse is in a large part reactive, in connection with current events. The situation is slightly different in the case of the print media. Three different types of discourse can be distinguished. The weekly Do Rzeczy continues the political tradition of Józef Piłsudski. It displays considerable interest in the former eastern borderlands and is distrustful towards Russia. The weekly Przegląd refers indirectly to the traditions of national democracy and the political realists of the People’s Republic of Poland period, being critical of Ukraine and pointing out the importance of relations with Russia. Gazeta Wyborcza has in large measure inherited the ideas of Jerzy Giedroyc. It emphasizes the need for reconciliation with Ukraine and for supporting it in its democratic and pro-European strivings.
Temperature and Distance Dependence of Tidal Circularization in Close Binaries: A Catalog of Eclipsing Binaries in the Southern Hemisphere Observed by the TESS Satellite
Authors: Justesen Anders B. , Albrecht Simon 
Published: May 2021

Abstract
Tidal forces are important for understanding how close binary stars and compact exoplanetary systems form and evolve. However, tides are difficult to model, and significant uncertainties exist about the strength of tides. Here, we investigate tidal circularization in close binaries using a large sample of well-characterized eclipsing systems. We searched TESS photometry from the southern hemisphere for eclipsing binaries. We derive best-fit orbital and stellar parameters by jointly modeling light curves and spectral energy distributions. To determine the eccentricity distribution of eclipsing binaries over a wide range of stellar temperatures (3000–50,000 K) and orbital separations a/R
1 (2–300), we combine our newly obtained TESS sample with eclipsing binaries observed from the ground and by the Kepler mission. We find a clear dependency of stellar temperature and orbital separation in the eccentricities of close binaries. We compare our observations with predictions of the equilibrium and dynamical tides. We find that while cool binaries agree with the predictions of the equilibrium tide, a large fraction of binaries with temperatures between 6250 K and 10,000 K and orbital separations between a/R
1 ∼ 4 and 10 are found on circular orbits, contrary to the predictions of the dynamical tide. This suggests that some binaries with radiative envelopes may be tidally circularized significantly more efficiently than usually assumed. Our findings on orbital circularization have important implications also in the context of hot Jupiters, where tides have been invoked to explain the observed difference in the spin–orbit alignment between hot and cool host stars.
Procedural fairness of objective and subjective performance evaluations: Exploring the combined effects of uncertainty and trust
Authors: Langevin Pascal , Mendoza Carla 
Published: May 2021

Les recherches empiriques sur les coûts et avantages des évaluations de performance subjectives comparées à objectives ont produit des résultats qui restent mitigés. Pour éclairer ce débat, nous examinons les effets de ces deux types d’évaluation sur la perception de justice procédurale des managers dans différents contextes combinant incertitude et confiance. L’objectif est, d’une part, d’identifier si un type d’évaluation de performance est perçue comme plus juste que l’autre dans certains contextes et, d’autre part, d’explorer comment ces perceptions de justice se forment. Pour traiter ces deux questions, nous analysons les données quantitatives et qualitatives recueillis auprès de 418 managers à l’aide d’un questionnaire basé sur des scénarios. Nos résultats montrent que les évaluations subjectives sont perçues comme plus justes que les évaluations objectives par les managers confrontés à des situations de forte incertitude et qui ont confiance dans leur supérieur. A l’inverse, les évaluations objectives sont perçues comme plus justes dans les situations où incertitude et confiance sont tous les deux faibles. Nos résultats montrent également que les managers forment leur jugement de justice en considérant deux dimensions : ils perçoivent que les évaluations subjectives leur offrent la possibilité d’exprimer leur point de vue, alors que les évaluations purement objectives sont vues comme plus précises et moins biaisées. Globalement, ces résultats suggèrent que les organisations peuvent améliorer leurs systèmes d’évaluation des performances, soit en utilisant les mesures appropriées au contexte, soit en agissant sur l’incertitude et/ou la confiance.
Traversées québécoises en littérature féministe : influences états-uniennes et françaises
Authors: Turbiau Aurore 
Published: May 2021

Cet article propose d’étudier la manière dont la littérature féministe québécoise s’est constituée, dans les années 1970, en relation avec les productions théoriques et littéraires françaises et américaines. Les Québécoises voyagent aux États-Unis et se nourrissent de ce qu’elles y apprennent ; les essais militants les intéressent, ceux de K. Millett, S. Firestone, B. Friedan ; mais le rapport d’influence avec les États-uniennes est unilatéral, les États-uniennes se souciant assez peu de ce qui se passe au Québec. En revanche, on peut parler de vrais échanges entre féministes françaises et québécoises ; elles partagent essais historiques et féministes, textes psychanalytiques ou littéraires ; elles participent aux mêmes revues et se retrouvent dans des congrès internationaux. Ainsi, au moment des années 1970, on peut parler de « traversées québécoises » : même si la littérature féministe québécoise ne s’est jamais placée en situation de dépendance par rapport aux créations états-uniennes et françaises, elle les a visitées pour en tirer de quoi se construire elle-même, avec ou sans leur participation active.

Authors: Fersini Elisabetta , Nozza Debora , Rosso Paolo 
Published: May 2021

Automatic Misogyny Identification (AMI) is a shared task proposed at the Evalita 2020 evaluation campaign. The AMI challenge, based on Italian tweets, is organized into two subtasks: (1) Subtask A about misogyny and aggressiveness identification and (2) Subtask B about the fairness of the model. At the end of the evaluation phase, we received a total of 20 runs for Subtask A and 11 runs for Subtask B, submitted by 8 teams. In this paper, we present an overview of the AMI shared task, the datasets, the evaluation methodology, the results obtained by the participants and a discussion about the methodology adopted by the teams. Finally, we draw some conclusions and discuss future work.
KonKretiKa @ CONcreTEXT: Computing concreteness indexes with sigmoid transformation and adjustment for context
Authors: Badryzlova Yulia 
Published: May 2021

The present paper is a technical report of KonKretiKa, a system for computation of concreteness indexes of words in context, submitted to the English track of the CONcreTEXT shared task. We treat concreteness as a bimodal problem and compute the concreteness indexes using paradigms of concrete and abstract seed words and distributional semantic similarity. We also conduct sigmoid transformation to achieve greater similarity to the psycholinguistically attested data, and apply dynamic adjustment of static indexes for sentential context. One of the modifications of the presented system ranked third in the task, with rs = .6634 and r = .6685 against the gold standard.

Published: May 2021

Abstract
Regulatory T cell (Treg) infusion for graft-versus-host disease treatment has been increasingly investigated. However, polyclonal Treg may suppress the desired graft-versus-leukemia effect. Although allogeneic-specific (allo-specific) Treg may provide a more-targeted graft-versus-host disease treatment, there is the need to develop easily translatable expansion protocols and to better characterize their specificity and mechanisms of suppression. In this article, we provide a robust protocol for human allo-specific Treg expansion and characterize their phenotype, potency, and specificity of suppression by testing different expansion conditions and suppression assay milieus. We found that higher concentrations of IL-2 during expansion with allogeneic APC yielded allo-specific Treg that were more-potent suppressors and displayed a more activated phenotype. Although responses to the same APC present during expansion were the most suppressed, responses to third-party APC partially matched to the expansion APC were still significantly more suppressed than responses to fully mismatched APC. Furthermore, suppression of responses to the expansion APC was strictly contact dependent, whereas suppression of responses to mismatched APC was partially independent of contact. Finally, distinct subsets in fresh and expanded Treg could be described using multidimensional visualization techniques. We propose that allo-specific Treg are HLA specific and that the mechanisms of suppression elicited depend on their compatibility with the stimulators.
A Comparative Study of Topical 5% 5-Fluorouracil with Needling versus 30% Trichloroacetic Acid with Needling in the Treatment of Plantar Warts
Authors: Basavarajappa Sushma Jankal , Subramaniyan Radhakrishnan , Dabas Rajeshwari , Lal Sandeep V. , Janney Manasa S. 
Published: May 2021

Background:
Warts are benign proliferations of keratinocytes caused by Human Papilloma Virus (HPV). Plantar warts are caused by HPV types 1, 2, 4, 27 and 57. It is challenging to treat them due to frequent recurrences.

Aim:
To compare the efficacy and safety of topical 5% 5-Fluorouracil (5-FU) with needling versus 30% Trichloroacetic acid (TCA) with needling in the treatment of plantar warts.

Materials and Methods:
Sixty consecutive patients of plantar warts were randomly allocated into two groups of 30 each and treated with either 30% TCA with needling or 5% 5-FU with needling once in four weeks, until complete clearance of warts or for a maximum of three sessions. Baseline clinical photographs were taken and subjective response at the end of treatment was recorded. Objective assessment at 4, 8, and 12 weeks was carried out and outcome was evaluated by reduction in number and size of warts. Adverse effects of each group were noted and compared. Follow-up of patients was done at 6 months for clinical assessment of results and to study recurrence.

Results:
Out of 30 patients in 30% TCA group, 28 patients (93.33%) had complete response and 02 patients (6.66%) had partial response at the end of 12 weeks. In 5-FU group, 26 patients (86.66%) showed complete response, 02 patients (6.66%) had partial response, and 02 patients (6.66%) had no response to treatment. The mean reduction in size and number of warts was better in the TCA group and was significant at 4th week of follow up while at the end of 8th week and 12th week, the response was identical. There was no recurrence of warts in the complete responders at the end of 6 months. The main adverse effect seen in both groups was pain at the needling site.

Conclusion:
Needling with both topical 5% 5-FU and 30% TCA are highly effective in clearing plantar warts. However, 30% TCA has the advantage of early action and complete clearance of plantar warts with fewer adverse effects.
Implementation and Status of Biogas Technology in Ethiopia- Case of Tigray Region

Published: May 2021

In Ethiopia, like most developing countries, the majority of households depend on wood and charcoal as their cooking energy resources. This energy has a direct impact on the forest coverage and its emissions have significant health issues. Biogas technology has introduced to address these problems and reduce energy poverty in developing countries. However, the success of this technology depends on many factors such as technology appropriateness, available skill, proper introduction, and government support to create favorable financial incentives. The objective of this paper is to make an overview assessment of biogas development programs in Ethiopia, identify development barriers and provide suggestions to mitigate these barriers. The national and regional biogas program of Ethiopia has implemented to give energy for cooking and to some extent for lighting. However, it has shown limited success over the years. The National Biogas Programme of Ethiopia has shown an overall 50% achievement while the Tigray region registered 55% achievement. In addition, the owner of the biogas facility in Tigray reported a 57% functionality rate but the lowest satisfaction level of 15%. Generally, the region has shown relatively better performance in terms of dissemination and functionality but a low satisfaction rate due to technical limitation, unsteady input, and financial factors.
Measurement report: Fourteen months of real-time characterisation of the submicronic aerosol and its atmospheric dynamics at the Marseille–Longchamp supersite

Published: May 2021

Abstract. This study reports results of PM1 chemical composition determined using a Time-of-Flight Aerosol Chemical Speciation Monitor
(ToF-ACSM) over a 14-month period (1 February 2017–13 April 2018) at the
Marseille–Longchamp supersite (MRS-LCP) in France. Parallel measurements were performed with an aethalometer, an ultrafine particle monitor and a suite of instruments to monitor regulated pollutants (PM2.5, PM10,
NOx, O3 and SO2). The average PM1 chemical composition
over the period was dominated by organic aerosol (OA; 49.7 %) and black
carbon (BC; 17.1 %), while sulfate accounted for 14.6 %, nitrate for 10.2 %, ammonium for 7.9 % and chloride for 0.5 % only. Wintertime was
found to be the season contributing the most to the annual PM1 mass
concentration (30 %), followed by autumn (26 %), summer (24 %) and
spring (20 %). During this season, OA and BC concentrations were found to
contribute 32 % and 31 % of their annual concentrations, respectively, as a combined result of heavy urban traffic, high emissions
from residential heating and low planetary boundary layer (PBL) height. Most
(75 %) of the 15 days exceeding the target daily PM2.5 concentration value recommended by the World Health Organization (WHO) occurred during this season. Local and long-range pollution episodes with
contrasting chemical composition could be distinguished, accounting for 40 %
and 60 % of the exceedance days, respectively. Enhanced OA and BC
concentrations, mostly originating from domestic wood burning under
nocturnal land breeze conditions, were observed during local pollution episodes, while high levels of oxygenated OA and inorganic nitrate were associated with medium-/long-range transported particles. In summertime, substantially higher concentrations of sulfate were found, with an average and a maximum contribution to the PM1 mass of 24 %
and 66 %, respectively. Results from k-means clustering analysis of daily profiles of sulfate concentrations clearly reveal the significant influence of local harbour/industrial activities on air quality in addition to the more regional contribution of shipping traffic that originates from
the Mediterranean basin.

Published: May 2021

Abstract. Within a short time after the outbreak of coronavirus
disease 2019 (COVID-19) in Wuhan, Hubei, the Chinese government introduced a nationwide lockdown to prevent the spread of the pandemic. The quarantine
measures have significantly decreased the anthropogenic activities, thus
improving air quality. To study the impacts caused by the lockdown on
specific source sectors and regions in the Yangtze River Delta (YRD), the
Community Multiscale Air Quality (CMAQ) model was used to investigate the
changes in source contributions to fine particulate matter (PM2.5) from
23 January to 28 February 2020, based on different emission control cases.
Compared to case 1 (without emission reductions), the total PM2.5 mass
for case 2 (with emission reductions) decreased by more than 20 % over the entire YRD, and the reduction ratios of its components were 15 %, 16 %,
20 %, 43 %, 34 %, and 35 % in primary organic aerosol (POA),
elemental carbon (EC), sulfate, nitrate, ammonium, and secondary organic
aerosol (SOA), respectively. The source apportionment results showed that
PM2.5 concentrations from transportation decreased by 40 %, while PM2.5 concentrations from
the residential and power sectors decreased by less than 10 % due to the
lockdown. Although all sources decreased, the relative contribution changed
differently. Contributions from the residential sector increased by more than
10 % to 35 %, while those in the industrial sector decreased by 33 %.
Considering regional transport, the total PM2.5 mass of all regions
decreased 20 %–30 % in the YRD, with the largest decreased value of
5.0 µg m−3 in Henan, Hebei, Beijing, and Tianjin (Ha-BTH). In Shanghai, the
lower contributions from local emissions and regional transmission (mainly
Shandong and Ha-BTH) led to the reduced PM2.5. This study suggests
adjustments of control measures for various sources and regions.
Industrial robot-based system design of thickness scanning measurement using ultrasonic

Published: May 2021

Abstract. Wall thickness is one of the core indicators for measuring the quality of large thin-walled parts such as rocket siding and
aircraft skin. However, the traditional handheld thickness measurement method has high labor intensity, low efficiency and poor accuracy
consistency. Therefore, an in situ ultrasonic automatic scanning thickness measurement method for large thin-walled parts based on industrial robots is proposed. This “industrial robot + ultrasound” integrated function is a
compact system, and a set of innovative methodological or technical solutions is presented, such as (i) TCP and UDP communication protocols being constructed to realize a high-speed and stable communication relationship
between the upper computer, robot motion controller and ultrasonic thickness measurement unit; (ii) a coupling gap adjustment method based on eddy-current sensors being adopted to ensure the adaptability of the ultrasonic probe to surface topography of the measured part during scanning
measurement; and (iii) a multi-sensor coordinate unified model and coupling gap state discrimination model being established for robot-aided thickness
measurement. To verify the feasibility of the proposed method, a series of
calibrations and experiments were designed based on the KUKA robot platform and the developed ultrasonic pulse measurement system. Finally, the industrial
robot-based ultrasonic thickness scanning measurement has been built and tested for performing the measurement of a rocket tank wall.
Subseasonal prediction of springtime Pacific–North American transport using upper-level wind forecasts

Published: May 2021

Abstract. Forecasts of Pacific jet variability are used to predict
stratosphere-to-troposphere transport (STT) and tropical-to-extratropical
moisture export (TME) during boreal spring over the Pacific–North American
region. A retrospective analysis first documents the regionality of STT and
TME for different Pacific jet patterns. Using these results as a guide,
Pacific jet hindcasts, based on zonal-wind forecasts from the European Centre
for Medium-Range Weather Forecasting Integrated Forecasting System, are
utilized to test whether STT and TME over specific geographic regions may be
predictable for subseasonal forecast leads (3–6 weeks ahead of time). Large
anomalies in STT to the mid-troposphere over the North Pacific, TME to the
west coast of the United States, and TME over Japan are found to have the best
potential for subseasonal predictability using upper-level wind forecasts. STT
to the planetary boundary layer over the intermountain west of the United
States is also potentially predictable for subseasonal leads but likely only
in the context of shifts in the probability of extreme events. While STT and
TME forecasts match verifications quite well in terms of spatial structure and
anomaly sign, the number of anomalous transport days is underestimated
compared to observations. The underestimation of the number of anomalous
transport days exhibits a strong seasonal cycle, which becomes steadily worse
as spring progresses into summer.
