Rythmes alimentaires : du fast au slow . Le cas de la marque Slow Food
Authors: Marrone Gianfranco 
Published: January 2021

Cet article vise à montrer, avec les instruments de l’analyse sémiotique, que Slow Food est une marque parfaite. D’un côté, cette marque naît par opposition à une autre marque très forte, le colosse mondial du fast food McDonald’s. De l’autre, cette opposition n’est pas, à l’origine, une offre de produits alternatifs à McDonald’s, de marchandises concurrentes à destination des consommateurs, mais une proposition de nouvelles valeurs : une formulation abstraite d’une forme de vie alternative à celle de la fast life. C’est uniquement dans un second temps, une fois la marque constituée (grâce à ses supports communicatifs), qu’elle se dote d’une série d’offres commerciales : nourriture, vins, lieux de restauration, édition, entreprises, des territoires entiers, voire des villes en régime slow . Ainsi, par un geste sémiotique absolu, Slow Food accomplit le procès discursif typique de toute marque et devient, comme l’aurait dit Lévi-Strauss, du « bon à penser ».
The determinants of acceptability and behavioural intention of automated vehicles – a review
Authors: Lemonnier Aurore , Adelé Sonia , Dionisio Corinne 
Published: January 2021

Sans le soutien du public, le déploiement des véhicules automatisés (VAs) est voué à l’échec. C’est pourquoi leur acceptabilité a été largement étudiée. Sur la base d’une revue de littérature incluant 113 études empiriques, ce document expose l’influence des modes de contact avec les VAs (aucune explication fournie, description écrite ou illustrée seulement, simulateur, expérience réelle) sur le lien entre l’acceptabilité et/ou l’intention comportementale et leurs déterminants sociodémographiques et psychologiques. L’analyse des variables dépendantes montre un manque de clarté sur ce qui est réellement mesuré et une hétérogénéité des mesures qui rendent les comparaisons difficiles. En effet, l’acceptabilité est souvent confondue avec l’intention d’usage. Les déterminants ont été séparés en deux groupes : les préférences, qui se réfèrent aux projections dans l’usage, et les perceptions, qui se réfèrent aux croyances. Les déterminants du groupe des préférences, et certains déterminants du groupe des perceptions (facilité d’utilisation, utilité perçue et attitudes), ne sont pas influencés par le mode de contact avec le VA. En effet, un mode de contact plus concret ne modifie pas les réponses des participants pour ces variables. Pour les autres déterminants du groupe des perceptions, le mode de contact avec le VA a un impact sur les réponses des participants. La confiance et la sécurité perçue sont influencées par le mode de contact. De manière plus marquée, nous avons observé que la relation entre l’acceptabilité et le niveau de connaissance ou de contrôle perçu pourrait être modérée par le mode de contact avec les VAs. Ces résultats nous amènent à encourager les recherches favorisant l’expérience réelle avec les VAs pour étudier leur acceptabilité. Enfin, il nous est impossible de statuer sur l’influence de plusieurs déterminants sur l’acceptabilité des VAs en raison de résultats contradictoires ou isolés. En conséquence, nous encourageons notamment la réplication systématique des effets observés et l’utilisation de méta-analyses. Une discussion des résultats récurrents mais aussi des lacunes tant théoriques que méthodologiques des études analysées est présentée. En outre, l’article souligne les défauts des recherches en termes d’échantillonnage, de robustesse statistique et met en évidence le manque d’études sur certains groupes tels que les non-conducteurs, certains types de véhicules (par exemple les trains), et certains aspects impliqués dans l’acceptabilité des VAs (notamment les questions éthiques). En conclusion, quelques pistes méthodologiques sont proposées pour l’étude des dispositifs technologiques peu ou pas connus des futurs utilisateurs ainsi qu’une réflexion sur l’utilité d’étudier l’acceptabilité de ces dispositifs méconnus.
How do novice and expert drivers prepare for takeover when they are drivengers of a level 3 autonomous vehicle? Investigation of their visual behaviour
Authors: Ouddiz Sharon , Paubel Pierre-Vincent , Lemercier Céline 
Published: January 2021

Les véhicules de demain seront capables de conduire en mode autonome la plupart du temps, permettant aux Conducteurs-Passagers (CP) d’un véhicule autonome de niveau 3 de faire ce qu’ils souhaitent jusqu’à l’occurrence d’une inopérabilité du système. Ceci implique pour les CP de se désengager de la tâche annexe menée durant le mode autonome afin de s’engager dans la tâche de conduite, au sein d’un intervalle de temps limité. Les études ont jusqu’ici permis de révéler les capacités restreintes des CP à reprendre la conduite après un mode autonome. Par ailleurs, il est attendu que l’autonomisation de la conduite s’accompagnera d’une diminution de l’expertise routière des usagers et des compétences associées. L’objectif de cette étude est d’investiguer comment les CP se préparent à la reprise de la conduite en fonction de leur niveau d’expertise routière. Les CP en conduite autonome de niveau 3 (n = 25) ont été invités à regarder un film durant une phase de conduite autonome de 30 minutes. Ils devaient ensuite se préparer à reprendre la conduite durant les 18 secondes d’alerte à la reprise. Les conducteurs (n = 29) ont effectué le même trajet en conduite manuelle, sans tâche annexe. L’attention allouée par les CP à la reprise de la conduite versus à la poursuite de la tâche annexe était investiguée par l’enregistrement de leur comportement visuel entre le début de l’alerte à la reprise et la désactivation effective du système autonome. Le diamètre pupillaire était enregistré en tant qu’indicateur de leur charge mentale. Les données oculométriques étaient comparées avec celles recueillies chez les conducteurs en condition non-autonome. Les résultats ont montré un comportement visuel détérioré chez les CP par rapport aux conducteurs. Les CP novices avaient le comportement visuel le plus dégradé durant cette période de préparation à la reprise. Finalement, la charge mentale des CP était tendanciellement plus élevée que celle des conducteurs. Les résultats suggèrent que les CP ne disposent pas de capacités attentionnelles suffisantes leur permettant de faire face aux exigences élevées imposées par la reprise de la conduite, particulièrement lorsque leur niveau d’expertise routière est faible.

Published: January 2021

Abstract
Photosensitivity is a sensitivity to UV radiation (UVR) commonly found in systemic lupus erythematosus (SLE) patients who have cutaneous disease. Upon even ambient UVR exposure, patients can develop inflammatory skin lesions that can reduce the quality of life. Additionally, UVR-exposed skin lesions can be associated with systemic disease flares marked by rising autoantibody titers and worsening kidney disease. Why SLE patients are photosensitive and how skin sensitivity leads to systemic disease flares are not well understood, and treatment options are limited. In recent years, the importance of immune cell–stromal interactions in tissue function and maintenance is being increasingly recognized. In this review, we discuss SLE as an anatomic circuit and review recent findings in the pathogenesis of photosensitivity with a focus on immune cell–stromal circuitry in tissue health and disease.

Published: January 2021

Abstract
Over the past decade, T cell immunotherapy has changed the face of cancer treatment, providing robust treatment options for several previously intractable cancers. Unfortunately, many epithelial tumors with high mortality rates respond poorly to immunotherapy, and an understanding of the key impediments is urgently required. Cancer-associated fibroblasts (CAFs) comprise the most frequent nonneoplastic cellular component in most solid tumors. Far from an inert scaffold, CAFs significantly influence tumor neogenesis, persistence, and metastasis and are emerging as a key player in immunotherapy resistance. In this review, we discuss the physical and chemical barriers that CAFs place between effector T cells and their tumor cell targets, and the therapies poised to target them.
Teaching for Abstraction: Teacher Learning
Authors: White Paul , Wilson Sue , Mitchelmore Michael 
Published: January 2021

Working collaboratively with the researchers, a small team of teachers developed and taught two Grade 6 mathematics lessons based on the Teaching for Abstraction model (White & Mitchelmore, 2010). This paper reports how one teacher learned about the model and implemented it in practice. It was found that she assimilated several key features of the model, such as starting with several embodiments of the target concept and guiding students to look for similarities between them. However, it was more difficult for her to help students abstract and reify the target concept and link it to other mathematical concepts. It was concluded that teachers also need to abstract Teaching for Abstraction, and need more embodiments of it before they can reify and implement an effective model.
Introducing Computer Adaptive Testing to a Cohort of Mathematics Teachers: The Case of Concerto
Authors: Shanmugam S. Kanageswari Suppiah , Kin Leong Chee 
Published: January 2021

This article describes a study that explores on-line assessment, with the objectives to identify features that support or impede the usability of Concerto, an on-line adaptive testing software that was developed by the Psychometrics Centre of the University of Cambridge. We report on the analysis of data collected during a one-month in-service programme organised for secondary teachers and teacher educators from the Southeast Asian Minister of Education Organisation (SEAMEO) region. The study identifies the challenges the participants encountered during a one-day workshop and evaluates thedifficulties of adopting Concerto to create a simple and an adaptive on-line mathematics test. While the small study limits the possibility of applicability for other samples, yet the findings of the study illustrate the complexity of using the Concerto’s features and the commonly occurring difficulties, providing the basis for the development of some new workshop materials that will contribute to the improvement of introductory Concerto workshops that will be conducted in the future.
A Model Eliciting Framework For Integrating Mathematics And Robotics Learning
Authors: Nutchey David 
Published: January 2021

Robotics is taught in many Australian ICT classrooms, in both primary and secondary schools. Robotics activities, including those developed using the LEGO Mindstorms NXT technology, are mathematics-rich and provide a fertile ground for learners to develop and extend their mathematical thinking. However, this context for learning mathematics is often under-exploited. In this paper a variant of the model construction sequence (Lesh, Cramer, Doerr, Post, & Zawojewski, 2003) is proposed, with the purpose of explicitly integrating robotics and mathematics teaching and learning. Lesh et al.’s model construction sequence and the model eliciting activities it embeds were initially researched in primary mathematics classrooms and more recently in university engineering courses. The model construction sequence involves learners working collaboratively upon product-focussed tasks, through which they develop and expose their conceptual understanding. The integrating model proposed in this paper has been used to design and analyse a sequence ofactivities in an Australian Year 4 classroom. In that sequence more traditional classroom learning was complemented by the programming of LEGO-based robots to ‘act out’ the addition and subtraction of simple fractions (tenths) on a number-line. The framework was found to be useful for planning the sequence of learning and, more importantly, provided the participating teacher with the ability to critically reflect upon robotics technology as a tool to scaffold the learning of mathematics.
Exploring Challenges in Integrating ICT in Secondary Mathematics with TPACK
Authors: Stoilescu Dorian 
Published: January 2021

This paper describes challenges encountered by three experienced secondary mathematics teachers when they try to integrate ICT in their classrooms. This study is based on the four dimension framework developed by Niess: 1) overarching conceptions of integrating ICT, 2) knowledge of instructional strategies and representations for teaching, 3) knowledge of students’ knowledge of technology; and 4) knowledge of curriculum and curriculum materials that integrate technology with learning. By using this analysis, we explore the challenges that teachers face on each of the four levels of integration ICT and suggest waysof improving these strategies in mathematical instruction.
Educating the Educators: Technology-Enhanced Mathematics Teaching and Learning
Authors: Kin Leong Chee 
Published: January 2021

Educational research has shown that teaching quality is one of the most important factors in raising student achievement. There is a compelling need for educators to keep abreast of the important developments that are taking place in educational arena. One of the educational areas that has massive development is the use of technology to enhance teaching and learning especially in mathematics. This development needs professional developmentamong educators. Being a regional science and mathematics education centre, the Southeast Asian Ministers of Education Organisation Regional Centre for Education in Science and Mathematics (SEAMEO RECSAM) has always been cognizant of the importance of these developments. Its training programmes are planned to incorporate these developments for in-service teachers, teacher educators and ministry of education mathematics officers. As the Centre's mandate aims to ensure that these participants from Southeast Asians countriesas well as those from outside the region are equipped with emerging educationaltechnology tools which can enhance teaching and learning of mathematics. This paper will share the Centre’s experiences in continuing professional development among mathematics teacher, teacher educators and officers from the ministry of education on educational innovation and technology.
How Can SEAMEO QITEP in Mathematics Help Indonesian Mathematics Teachers to Help Their Students to be Independent Learners in the Case of Disaster Risk Reduction (DRR)?
Authors: Shadiq Fadjar 
Published: January 2021

There are a number of disasters threats in Indonesia, such as earthquakes, tsunamis, volcanic eruptions, fires, landslides and floods. When a natural hazard strikes, children are among the most vulnerable population group, especially those attending school in the times of disaster. What people know is more important than what they have when it comes to saving lives and reducing loss. It implies that students should also learn DRR during the teaching and learning of mathematics. This paper reports on a number of studies conducted by SEAMEO QITEP across the years 2012 – 2015 that attempted to improve both teachers and students learningoutcomes.

Published: January 2021

Continuous entomological monitoring of Cullicoides spp., which is being conducted starting from 2014 have so far yielded significant results related to biodiversity and seasonal dynamics of these insects Serbia. The research we have done so far has contributed to mapping the geographical distribution of the species we encounter as well as the variations in the number of populations in different years. As monitoring continues, we receive new valuable data every year that will help predict the movement of these insects on the basis of biclimatograms and enable preventative action to be taken to counteract them. Unfortunately, starting in 2019, monitoring has been split into three institutions (NIVS Belgrade, NIV Novi Sad and VSI Kraljevo) so that this has lost insight into the biodiversity, sex ratio, and most importantly the age of the females that are the primary vectors. In our work, therefore, we can provide only the results of testing the biodiversity and seasonal dynamics of Cullicoides spp. during 2019 in the epizootiological area of NIVS Belgrade, VSI Šabac, VSI Pančevo, VSI Požarevac, and VSI Zaječar, while we did not divide samples from VSI Jagodina for the fourth consecutive year. Culicoides spp. from Obsoletus complexes were established at 59.91%, from the Pulicaris complex were established at 34.06% and other types of culicoids have been established in less than 10% of the examined samples.
When ‘negativity’ becomes obstructive: a novel exploration of the two-factor model of the Self-Compassion Scale and a comparison of self-compassion and self-criticism interventions
Authors: Mantzios Michail , Koneva Anastasija , Egan Helen 
Published: January 2021

BackgroundSelf-compassion is a tendency to respond to personal feelings of distress in a kind and understanding way, and to become aware that facing difficulties and adversity is part of a common human experience that is shared by all hu-mans. The Self Compassion Scale (SCS) includes negative items measuring self-judgement, isolation and over-identification, which are at the opposite end of the spectrum to self-kindness, common humanity and mindfulness. Some researchers have argued that the link between self-compassion and psychopathology is inflated by the inclu-sion of these negative items. Moving away from factorial structures and advanced statistics used in recent research, we present a different way of exploring the conceptualisation of self-compassion theory and the way it is measured.Participants and procedureStudy 1 set out to support the inclusion (or exclusion) of the negative items within the SCS, by investigating the cor-relation between the negative items and the positive items altered to reflect the exact opposite of the original posi-tive items of the scale (i.e., self-unkindness, disjointed humanity, and mindlessness). Study 2 was an experiment exploring differences between self-compassion and self-criticism 5-minute interventions on state self-compassion, state mindfulness and state anxiety. The interventions were separated to represent the positive or negative ele-ments, rather than a mixture of the interventions.ResultsIf the main argumentation against the use of the overall score of the self-compassion scale is the inflation of the neg-ative items, then the results support the inclusion of the negative items within the SCS, as the altered positive items show a similar inflation to the original negative items when observing a significant positive relationship. No differ-ences were found between the two interventions and the overall scores; nevertheless, mindfulness and self-judgment subscales appeared to significantly change only for the self-compassion group.ConclusionsWhile the debate around the self-compassion scale continues, the literature emphasizing self-criticism does not translate into inflation as suggested, and does not propose effective practices. Explanations of findings, limitations and suggestions for future research are discussed.

PurposeMatch analysis must adopt multidimensional performance indicators, which include analysing playing position
influence in official matches. The study compared physical, technical, and network variables of Brazilian soccer athletes
from different positions.MethodsOverall, 17 professional soccer athletes (3 central defenders, 4 fullbacks, 5 central midfielders, 3 wide forwards,
2 central forwards) were monitored during 6 official matches. External load data were collected with a 10-Hz GPS device.
The number of passes, shots, losses of ball possession, and balls recovered were coded. Athletes’ network centralities were
assessed with social network analysis.ResultsCentral midfielders (10.0 ± 0.8 km) and wide forwards (10.4 ± 0.4 km) covered higher distances than central
defenders (10.2% and 14.7%, respectively; <i>ES</i> = 0.392) and central forwards (16.7% and 21.5%, respectively; <i>ES</i> = 0.392).
Wide forwards performed more high-intensity running (17.8 ± 2.5) than central defenders (91.4%; <i>ES</i> = 0.377) and forwards
(88.9%; <i>ES</i> = 0.377). Central defenders (43.1 ± 22.3) and fullbacks (41.5 ± 17.3) performed more passes than forwards
(453.4% and 470.0%, respectively; <i>ES</i> = 0.383). Central defenders (0.16 ± 0.04 AU) and fullbacks (0.14 ± 0.05 AU) presented
a higher degree of centrality than all other positions (<i>ES</i> = 0.651). Wide forwards presented a higher degree of prestige (0.13
± 0.05 AU) than central defenders (325%; <i>ES</i> = 0.242). The highest prominence was observed for wide (0.12 ± 0.01 AU)
and central forwards (0.12 ± 0.03 AU) (<i>ES</i> = 0.509).ConclusionsPhysical and technical responses and network properties are position-specific among sub-elite athletes.

PurposeHow crucial is good serving to succeed in modern days women’s world class tennis? The study aimed to systematically analyse serve efficiency and serving behaviour in elite women’s tennis over a course of 14 years to identify possible trainings patterns.MethodsAnalyses included historical data collected from all matches at the Ladies Wimbledon Championships between 2002 and 2015 (matches: <i>n</i> = 1771; service games: <i>n</i> = 37,717; serves: <i>n</i> = 248,135). The study focused on two main comparisons, serve efficiency development between 2002 and 2015 and possible differences inside the women’s tennis world class, i.e. by comparing 1<sup>st</sup> tournament week results (matches: <i>n</i> = 1562; service games: <i>n</i> = 33,150; serves: <i>n</i> = 218,028) and 2<sup>nd</sup> tournament week results (matches: <i>n</i> = 209; service games: <i>n</i> = 4567; serves: <i>n</i> = 30,107).ResultsAn increase over time has been observed for the percentages of service games won (<i>p</i> < 0.001), 1st service points won (<i>p</i> < 0.05), and aces served (<i>p</i> < 0.01), whereas double faults served (<i>p</i> < 0.05) and serve and volley points played (<i>p</i> < 0.001) decreased significantly. Direct comparisons of the 1<sup>st</sup> and 2nd tournament week results favour players competing in the 2<sup>nd</sup> tournament week, showing significant advantages in the percentages of service games won (<i>p</i> < 0.01), 1<sup>st</sup> service points won (<i>p</i> < 0.05) and aces served (<i>p</i> < 0.001).ConclusionsAn increased serve efficiency over time was observed, particularly for 1<sup>st</sup> tournament week results, indicating
a more extended women’s world class cohort. However, direct comparisons favour players competing in the 2<sup>nd</sup> tournament
week.
