Mathematics Assessment Practices of Primary School Teachers in France
Authors: Sayac Nathalie , Veldhuis Michiel 
Published: October 2021

Abstract
We investigated French primary school teachers’ assessment practice in mathematics. Using an online questionnaire on teachers’ background, teaching, and grading practice, we were able to determine assessment profiles of 604 primary school teachers. As evidenced by the teachers’ scores on the latent factors Assessment purposes, Assessment practices, and Differentiation, teachers with the profile of Enthusiastic assessors view assessment as more useful and use it more often to adapt their instruction than teachers with the profile of Unenthusiastic assessors. This can be useful for practice and sheds more light on French teachers’ assessment practices in mathematics. It is also interesting to compare the results of this survey with those from China and the Netherlands, as the differences reflect different assessment cultures and may shed light on some of the results of international large-scale assessments such as PISA.

Published: October 2021

AbstractAnalyzing seismic data to get information about earthquakes has always been a major task for seismologists and, more in general, for geophysicists. Recently, thanks to the technological development of observation systems, more and more data are available to perform such tasks. However, this data “grow up” makes “human possibility” of data processing more complex in terms of required efforts and time demanding. That is why new technological approaches such as artificial intelligence are becoming very popular and more and more exploited. In this paper, we explore the possibility of interpreting seismic waveform segments by means of pre-trained deep learning. More specifically, we apply convolutional networks to seismological waveforms recorded at local or regional distances without any pre-elaboration or filtering. We show that such an approach can be very successful in determining if an earthquake is “included” in the seismic wave image and in estimating the distance between the earthquake epicenter and the recording station.

AbstractWe conducted a scoping review of studies on health outcomes from electronic nicotine delivery systems (ENDS). The objective was to identify, narratively synthesize, assess the strength and quality of evidence and critically appraise studies that have reported disease end points associated with the use of ENDS. We included published literature on the health impact of ENDS from 01/01/2015 until 01/02/2020 following the PRISMA guidelines using PubMed, Embase, Scopus and Google Scholar. The database search identified 755 studies, and other sources 265; 37 studies met final eligibility criteria. Levels of evidence included 24(65%) cross-sectional, one (2.7%) case–control and six (16%) case studies, four (11%) cohort studies, one (2.7%) randomized controlled trial (RCT) and one (2.7%) meta-analysis; 27(73%) studies reported only on harms, eight (22%) reported on benefits, two (2%) on benefits and harms. Quality ratings were poor in 20 (54%), fair in 9(24%) and good in 8(22%) of studies. In our review, ENDS was not shown to be causative for harmful cardiovascular disease (CVD) outcomes and shown to be beneficial for hypertensive patients. Switching from cigarettes to e-cigarettes resulted in reduced exacerbations of chronic obstructive pulmonary disease (COPD), with no evidence of long-term deterioration in lung function. Mental Health, cancer and mortality were not adequately studied to form any consensus. Our review has not demonstrated ENDS to be causative of harmful CVD outcomes; furthermore switching from cigarettes to e-cigarettes was associated with improved hypertensive control and reduced exacerbations of COPD, with no evidence of increased asthma risk or long-term respiratory harm. Mental health, cancer and mortality outcomes have not been adequately studied to form a conclusion. Overall, the findings of our review did not provide evidence to counter the consensus held by many that ENDS use is safer than the risks posed from smoking cigarettes.

AbstractWe studied the predictive value of the PaO2/FiO2 ratio for classifying COVID-19-positive patients who will develop severe clinical outcomes. One hundred fifty patients were recruited and categorized into two distinct populations (“A” and “B”), according to the indications given by the World Health Organization. Patients belonging the population “A” presented with mild disease not requiring oxygen support, whereas population “B” presented with a severe disease needing oxygen support. The AUC curve of PaO2/FiO2 in the discovery cohort was 0.838 (95% CI 0.771–0.908). The optimal cut-off value for distinguishing population “A” from the “B” one, calculated by Youden’s index, with sensitivity of 71.79% and specificity 85.25%, LR+4.866, LR−0.339, was < 274 mmHg. The AUC in the validation cohort of 170 patients overlapped the previous one, i.e., 0.826 (95% CI 0.760–0.891). PaO2/FiO2 ratio < 274 mmHg was a good predictive index test to forecast the development of a severe respiratory failure in SARS-CoV-2-infected patients. Moreover, our work highlights that PaO2/FiO2 ratio, compared to inflammatory scores (hs-CRP, NLR, PLR and LDH) indicated to be useful in clinical managements, results to be the most reliable parameter to identify patients who require closer respiratory monitoring and more aggressive supportive therapies.

AbstractIn this study of patients admitted with COVID-19, we examined differences between the two waves in patient characteristics and outcomes. Data were collected from the first COVID-19 admission to the end of study (01/03/2020–31/03/2021). Data were adjusted for age and sex and presented as odds ratios (OR) with 95% confidence intervals (CI). Among 12,471 admissions, 1452 (11.6%) patients were diagnosed with COVID-19. On admission, the mean (± SD) age of patients with other causes was 68.3 years (± 19.8) and those with COVID-19 in wave 1 was 69.4 years (± 18.0) and wave 2 was 66.2 years (± 18.4). Corresponding ages at discharge were 67.5 years (± 19.7), 63.9 years (± 18.0) and 62.4 years (± 18.0). The highest proportion of total admissions was among the oldest group (≥ 80 years) in wave 1 (35.0%). When compared with patients admitted with other causes, those admitted with COVID-19 in wave 1 and in wave 2 were more frequent in the 40–59 year band: 20.8, 24.6 and 30.0%; consisted of more male patients: 47.5, 57.6 and 58.8%; and a high LACE (Length of stay, Acuity of admission, Comorbidity and Emergency department visits) index (score ≥ 10): 39.4, 61.3 and 50.3%. Compared to wave-2 patients, those admitted in wave 1 had greater risk of death in hospital: OR = 1.58 (1.18–2.12) and within 30 days of discharge: OR = 2.91 (1.40–6.04). Survivors of COVID-19 in wave 1 stayed longer in hospital (median = 6.5 days; interquartile range = 2.9–12.0) as compared to survivors from wave 2 (4.5 days; interquartile range = 1.9–8.7). Patient characteristics differed significantly between the two waves of COVID-19 pandemic. There was an improvement in outcomes in wave 2, including shorter length of stay in hospital and reduction of mortality.

AbstractThis study investigated the response to BNT162b2 mRNA COVID-19 vaccine among healthcare workers (HCWs) in an Italian teaching hospital. 444 participants were surveyed with either multiple RT-PCR assays for detection of SARS-CoV-2 nucleic acid in nasopharyngeal swabs or serology testing for the research of virus-specific immunoglobulins. Adverse events following immunization (AEFI) were reported. Two weeks after the first dose anti-SARS-CoV-2 antibodies exceeded reactivity cut-off in 82.5% the participants. Four HCWs tested positive at nasopharyngeal swab after 3 months. More than three-quarters reported AEFIs. Our findings offer an insight regarding the vaccine response after 3 months from its administration, with a special focus on effectiveness data, as well as the type and number of AEFIs complained by HCW recipients. The presented study may serve as reference for future research which will be necessary to explore the long-term safety of this vaccine, especially in population at high risk for infection, such as HCWs.
Global controversy in oyster systematics and a newly described species from SE Asia (Bivalvia: Ostreidae: Crassostreinae)
Authors: Sigwart Julia D. , Wong Nur Leena W. S. , Esa Yuzine 
Published: October 2021

AbstractThe diversity of native oysters in many regions is overshadowed by the global dominance of a few economically important species. Here we describe the Muar Oyster, Crassostrea (Magallana) saidii sp. nov., first reported as an established local fishery renowned for exceptional and distinctive flavour over 160 years ago by British colonial officials in Malaysia, but as yet never formally named or described as a species. This new species has a subtle but clear morphological diagnosis dependent on three-dimensional characters, which has long been recognised by local fishers to differentiate the new species from co-occurring C. (M.) belcheri (G. B. Sowerby II, 1871). The Indo-Pacific clade Magallana Salvi & Mariottini, 2016 in Salvi and Mariottini 2017 is a phylogenetically distinct group that nonetheless cannot be morphologically separated from the broader genus Crassostrea Sacco, 1897. Fossils or species known only from shell specimens, though morphologically distinct species, cannot be classified as Magallana, Talonostrea Li & Qi, 1994, or Crassostrea s.s.; therefore, we revise these groups as sub-genera within Crassostrea. Our analysis of the COI barcoding fragment from previously published sequences of all available Magallana species found that gene is not sufficient to separate several economically important species, and revealed more than 5% of sequences in GenBank represent identification errors. The new species Crassostrea (Magallana) saidii sp. nov., which is genetically, morphologically, and gastronomically distinct, is known from only one population under potential threat from urbanisation. Many more global species of Magallana remain undescribed. The systematics of this group is critical to understand the diversity of global oysters, and to understand the sustainable use of species grown worldwide for centuries as our food.
Cardiac sarcomere mechanics in health and disease
Authors: Crocini Claudia , Gotthardt Michael 
Published: October 2021

AbstractThe sarcomere is the fundamental structural and functional unit of striated muscle and is directly responsible for most of its mechanical properties. The sarcomere generates active or contractile forces and determines the passive or elastic properties of striated muscle. In the heart, mutations in sarcomeric proteins are responsible for the majority of genetically inherited cardiomyopathies. Here, we review the major determinants of cardiac sarcomere mechanics including the key structural components that contribute to active and passive tension. We dissect the molecular and structural basis of active force generation, including sarcomere composition, structure, activation, and relaxation. We then explore the giant sarcomere-resident protein titin, the major contributor to cardiac passive tension. We discuss sarcomere dynamics exemplified by the regulation of titin-based stiffness and the titin life cycle. Finally, we provide an overview of therapeutic strategies that target the sarcomere to improve cardiac contraction and filling.
Stigma in Psychiatry: Impact of a Virtual and Traditional Psychiatry Clerkship on Medical Student Attitudes
Authors: Bazaid Khalid , Simas Kevin , Bezzahou Abdellah 
Published: October 2021

Abstract
Objective
The objective of the study was to assess the change in medical students’ attitudes towards psychiatry following a virtual clerkship experience compared to a traditional clerkship experience.

Method
Ninety-seven medical students from the University of Ottawa were assessed pre- and post-clerkship on the ATP-30 (Attitudes Towards Psychiatry-30) measure. Cohorts of students were categorized as pre-COVID or during-COVID depending on when and how they experienced their clerkship (traditional or virtual). The total student response rate was approximately 48%. A quasi-experimental design was implemented, and non-parametric statistics were used to analyze the data.

Results
Medical students’ overall attitudes towards psychiatry improved from pre- to post-clerkship, with the type of clerkship experience (traditional or virtual) having no significant impact on the magnitude to which attitudes improved.

Conclusion
Implementation of a virtual clerkship in psychiatry did not deteriorate medical student attitudes towards psychiatry as a specialty, with both the traditional and virtual clerkship program enhancing students’ attitudes towards psychiatry favorably.
Digital twins of the mooring line tension for floating offshore wind turbines to improve monitoring, lifespan, and safety
Authors: Walker Jake , Coraddu Andrea , Collu Maurizio , Oneto Luca 
Published: October 2021

AbstractThe number of installed floating offshore wind turbines (FOWTs) has doubled since 2017, quadrupling the total installed capacity, and is expected to increase significantly over the next decade. Consequently, there is a growing consideration towards the main challenges for FOWT projects: monitoring the system’s integrity, extending the lifespan of the components, and maintaining FOWTs safely at scale. Effectively and efficiently addressing these challenges would unlock the wide-scale deployment of FOWTs. In this work, we focus on one of the most critical components of the FOWTs, the Mooring Lines (MoLs), which are responsible for fixing the structure to the seabed. The primary mechanical failure mechanisms in MoLs are extreme load and fatigue, both of which are functions of the axial tension. An effective solution to detect long-term drifts in the mechanical response of the MoLs is to develop a Digital Twin (DT) able to accurately predict the behaviour of the healthy system to compare with the actual one. Moreover, we will develop another DT able to accurately predict the near future axial tension as an effective tool to improve the lifespan of the MoLs and the safety of FOWT maintenance operations. In fact, by changing the FOWT operational settings, according to the DT prediction, operators can increase the lifespan of the MoLs by reducing the stress and, additionally, in the case where FOWT operational maintenance is in progress, the prediction from the DT can serve as early safety warning to operators. Authors will leverage operational data collected from the world’s first commercial floating-wind farm [the Hywind Pilot Park (https://www.equinor.com/en/what-we-do/floating-wind/hywind-scotland.html.)] in 2018, to investigate the effectiveness of DTs for the prediction of the MoL axial tension for the two scenarios depicted above. The DTs will be developed using state-of-the-art data-driven methods, and results based on real operational data will support our proposal.
Adaptation of a school-based mental health literacy curriculum: from Canadian to English classrooms

Published: October 2021

AbstractBackgroundSchool-based mental health literacy (MHL) interventions are increasingly trialled outside of the country in which they were developed. However, there is a lack of published studies that qualitatively explore their cultural adaptation. This study investigated the reasons for adaptations made and suggested to a Canadian MHL curriculum (The Guide) within the English school context.MethodSemi-structured interviews were conducted with 11 school staff responsible for the planning and/or implementation of The Guide across three schools in the South East of England, as part of the Education for Wellbeing (EfW) feasibility study. Transcripts were analysed using a hybrid, deductive-inductive thematic analysis.ResultsAdaptations made and suggested included dropping and emphasising content, and adapting language, examples and references. Most adaptations were proactive and related to The Guide's implementation methods, including developing more interactive and student-led approaches.Staff Capacity and Expertise,Timetabling,andAccessibility of Resourceswere identified as logistical reasons for adaptations. Philosophical reasons includedConsistency of Messages,Student Characteristics,Reducing Stigma and Empowering Students,National and Local Context,andAppropriate Pedagogic Practices.ConclusionOverall, recommendations were for immediately implementable lesson plans informed by teachers' knowledge about best pedagogic practices in England. Adequate training, attended by both senior leadership and those implementing, was also emphasised. While ensuring that the core components are clear, MHL interventions should be developed with a necessary level of flexibility to accommodate contextual characteristics. Future research should ensure that adaptations are captured through process and implementation evaluations conducted alongside efficacy trials.
Affective Polarization and the Populist Radical Right: Creating the Hating?
Authors: Harteveld Eelco , Mendoza Philipp , Rooduijn Matthijs 
Published: October 2021

AbstractDo populist radical right (PRR) parties fuel affective polarization? If so, how and under which circumstances? Based on a comparative cross-country analysis covering 103 elections in 28 European countries and an examination of longitudinal data from the Netherlands, we show that PRR parties occupy a particular position in the affective political landscape because they both radiate and receive high levels of dislike. In other words, supporters of PRR parties are uniquely (and homogeneously) negative about (supporters of) mainstream parties and vice versa. Our analyses suggest that these high levels of antipathy are most likely due to the combination of these parties' nativism and populism – two different forms of ingroup–outgroup thinking. Our findings also suggest that greater electoral success by PRR parties reduces dislike towards them, while government participation appears threatening to all voters except coalition partners.
Arrived in Power, and Yet Still Disgruntled? How Government Inclusion Moderates ‘Protest Voting’ for Far-Right Populist Parties in Europe
Authors: Muis Jasper , Brils Tobias , Gaidytė Teodora 
Published: October 2021

AbstractWhile debates about far-right populism often concentrate on Central and Eastern Europe, research on these parties predominantly focuses on Western countries. Addressing this remarkable gap, this article revisits the ‘protest voting’ explanation for electoral support for the far right. Using European Social Survey data (2002–16) from 22 countries, we show that political dissatisfaction is a stronger explanatory factor when far-right parties are in opposition, but is a less important determinant of electoral support when they are in government. Previous findings based on Western Europe – which similarly showed that the anti-elite hypothesis is less relevant when far-right parties join government coalitions – travel well to post-communist European countries. In Hungary and Poland, we even find that far-right voters have become less distrustful of national political institutions than the rest of the electorate. Our conclusion implies that anti-elite populism is context-dependent and has limited use for understanding successes of leaders such as Wilders, Salvini and Orbán.
When Is A Pledge A Pledge?
Authors: Krishnarajan Suthan , Jensen Carsten 
Published: October 2021

AbstractDespite the central role of election pledges in modern representative democracy, it remains uncertain how voters define pledges. We examine this by focusing on four rhetorical dimensions of political statements: the pledge giver, the formulation of commitment, the policy content and quantification. In three conjoint experiments on representative samples totalling around 6,000 respondents in the United States, Britain and Denmark, we find remarkably consistent results. On the one hand, voters consistently differentiate between statements in a highly focused manner: a promise is a promise if it is sincere and realistic – no matter who made it and whether it can be checked. On the other hand, voters are not willing to hold their party accountable for a given statement – even if they consider it an election pledge. We demonstrate that this is the perceptual logic of election pledges in Western democracies.
Opportunity cost determines free-operant action initiation latency and predicts apathy

Published: October 2021

AbstractBackgroundApathy, a disabling and poorly understood neuropsychiatric symptom, is characterised by impaired self-initiated behaviour. It has been hypothesised that the opportunity cost of time (OCT) may be a key computational variable linking self-initiated behaviour with motivational status. OCT represents the amount of reward which is foregone per second if no action is taken. Using a novel behavioural task and computational modelling, we investigated the relationship between OCT, self-initiation and apathy. We predicted that higher OCT would engender shorter action latencies, and that individuals with greater sensitivity to OCT would have higher behavioural apathy.MethodsWe modulated the OCT in a novel task called the ‘Fisherman Game’, Participants freely chose when to self-initiate actions to either collect rewards, or on occasion, to complete non-rewarding actions. We measured the relationship between action latencies, OCT and apathy for each participant across two independent non-clinical studies, one under laboratory conditions (n = 21) and one online (n = 90). ‘Average-reward’ reinforcement learning was used to model our data. We replicated our findings across both studies.ResultsWe show that the latency of self-initiation is driven by changes in the OCT. Furthermore, we demonstrate, for the first time, that participants with higher apathy showed greater sensitivity to changes in OCT in younger adults. Our model shows that apathetic individuals experienced greatest change in subjective OCT during our task as a consequence of being more sensitive to rewards.ConclusionsOur results suggest that OCT is an important variable for determining free-operant action initiation and understanding apathy.
