Do Coronal Loops Oscillate in Isolation?
Authors: Hindman Bradley W. , Jain Rekha 
Published: October 2021

Abstract
Images of the solar corona by extreme-ultraviolet telescopes reveal elegant arches of glowing plasma that trace the corona’s magnetic field. Typically, these loops are preferentially illuminated segments of an arcade of vaulted field lines and such loops are often observed to sway in response to nearby solar flares. A flurry of observational and theoretical effort has been devoted to the exploitation of these oscillations with the grand hope that seismic techniques might be used as probes of the strength and structure of the corona’s magnetic field. The commonly accepted viewpoint is that each visible loop oscillates as an independent entity and acts as a one-dimensional wave cavity for magnetohydrodynamic kink waves. We argue that for many events, this generally accepted model for the wave cavity is fundamentally flawed. In particular, the 3D magnetic arcade in which the bright loop resides participates in the oscillation. Thus, the true wave cavity is larger than the individual loop and inherently multidimensional. We derive the skin depth of the near-field response for an oscillating loop and demonstrate that most loops are too close to other magnetic structures to oscillate in isolation. Further, we present a simple model of a loop embedded within an arcade and explore how the eigenmodes of the arcade and the eigenmodes of the loop become coupled. In particular, we discuss how distinguishing between these two types of modes can be difficult when the motions within the arcade are often invisible.

Published: October 2021

Background: The study of readiness to change in the context of the University is needed in a situation to prepare for the 4.0 industrial revolution at the University which demands preparation in facing the VUCA era. The university is also in danger of being disrupted if it does not immediately make changes and adjustments to its role in the world of education. therefore readiness for change is the key for organizations to respond quickly and successfully to change. Methods: review the literature with a literature search strategy through publish or perish (the keywords used are readiness to change, universities, tertiary institutions). Results: 96 journal articles were found in publish or perish (step 1). The author manually screened the titles for inclusion and exclusion criteria to obtain 15 articles (step 2). All articles were subjected to an abstract review for screening according to criteria. From the results of the final selection, 11 reviewed journal articles were obtained. Conclusion: Acceptance and readiness to change is an important part of the organization especially the University which requires immediate attention. Need to be open to changes made before preparing for change. Alignment of the organization's vision and mission with employees' personal needs to be created by communicating messages of change so that they tend to have a positive attitude towards organizational change. Besides, trust in management proved to be important in implementing strategic decisions and an important determinant of employee openness to change. Keywords: Readiness to Change, University, Campus
Entre éducation populaire et scolaire, une histoire croisée des acteurs de l’école
Authors: Netter Julien 
Published: October 2021

Les pratiques des différents personnels encadrant aujourd’hui l’activité des enfants à l’école découlent d’une double histoire, celle de l’éducation populaire et de l’enseignement scolaire. Cet article vise à en retracer les grandes étapes, à partir de quatre mouvements principaux : la constitution d’un lien original fort entre l’école républicaine et le mouvement laïque, l’émergence d’une nouvelle idée de l’éducation populaire après 1945 portée par des enseignants militants, la disjonction des mouvements d’éducation populaire et de l’école dans les années 1970 parallèle à la transformation des pratiques d’enseignement, et enfin la territorialisation des liens entre école et « nouvelle » éducation populaire.
Ludothécaires et champ professionnel du jeu
Authors: Hernandez Yannick , Rubi Stéphanie , Tozzi Pascal 
Published: October 2021

Depuis 1968, les ludothèques s’inscrivent dans les politiques territoriales dédiées à la jeunesse, l’enfance, la culture. La progressive professionnalisation du métier de ludothécaire s’accompagne de la défense d’une juridiction dans un espace social concurrentiel. Ce groupe professionnel, jouant de diverses politiques intersectorielles et dépendant d’institutions de tutelle de plus en plus inscrites dans des dynamiques d’évaluation et d’efficience, fait face à des dilemmes, notamment celui de préserver « le jeu pour le jeu » – au cœur de leur référentiel professionnel – tout en faisant valoir le caractère plurigénérationnel et les bénéfices sociaux et éducatifs de leur action, surtout auprès des enfants et des jeunes.
La Recherche et l’Innovation en France
Authors: Ollivier Anne-Cécile 
Published: October 2021

Le « financement sur projet » apparaît, au niveau international, comme un mécanisme de plus en plus utilisé par les pouvoirs publics pour soutenir les activités de recherche, de développement et d’innovation menées par les acteurs publics et privés. Les objectifs auxquels il est supposé répondre sont variés : optimiser l’usage des fonds publics, promouvoir des sujets de recherche « stratégiques », favoriser l’interdisciplinarité ou les partenariats public-privé… Malgré les nombreuses vertus attribuées à l’instrument, la montée en puissance de ce type de financement ne va pourtant pas sans susciter des controverses, tout particulièrement en France. Ce chapitre a pour objectif de porter un double regard, à la fois quantitatif et qualitatif, sur ce sujet. Il propose dans un premier temps une mesure du poids de l’instrument « financement sur projet » dans les crédits publics de soutien à la RDI, en comparant la France à d’autres pays de l’OCDE. Cette mesure place a priori la France parmi les plus petits utilisateurs du financement sur projet. Dans un deuxième temps, toutefois, le texte explore la nécessaire distinction entre financement sur projet et activité sur projet : le principe de couverture partielle du coût des projets, en France, aboutit en effet à ce que la part d’activité sur projet soit plus importante que la part de financement sur projet. D’autres particularités françaises sont relevées, telles que la place importante des appels à projets collaboratifs, qui impliquent un montage plus lourd et une réduction de la dotation de chaque partenaire. Ces modalités spécifiques contribuent à expliquer le paradoxe d’un instrument dont l’usage apparemment limité (par rapport aux financements « récurrents ») est pourtant perçu par les opérateurs de recherche comme excessif au regard des coûts qu’il entraîne, en temps et en argent. Ce chapitre rappelle que le financement sur projet est un outil dont on peut choisir les caractéristiques. L’important est que ce choix soit fait en fonction d’objectifs clairement définis, explicites et collectivement assumés. Ce n’est pas suffisamment le cas dans l’état actuel des pratiques françaises.
La Recherche et l’Innovation en France
Authors: Bitard Pierre 
Published: October 2021

Trois ans après l’obtention de leur diplôme, les docteurs affichent, en France, un taux de chômage de 10 %, taux deux fois plus élevé que celui des masters ingénieur. Cette mauvaise performance s’explique notamment par la réticence à l’embauche et la longue durée de probation exigée avant un emploi stable. Renforcer la confiance dans les compétences des docteurs passe par un travail impliquant les parties prenantes : docteurs et doctorants, financeurs et intermédiaires, formateurs et employeurs. Un rôle central revient évidemment aux Écoles doctorales, qui ne disposent pas toutes de moyens comparables. Mais elles ne sont pas les seules en cause. Les suggestions faites ici sont des reprises de comportements vertueux déjà à l’œuvre, ou un rappel à un ordre supérieur (à l’échelon européen par exemple). Ce travail en cours les synthétise et des discussions collectives suivront pour envisager des généralisations ; l’harmonisation et la mutualisation recommandées portent sur la sélection à l’entrée, les voies d’implication des encadrants, l’offre de formation des Écoles doctorales et leur capacité d’animation, l’implication des directions des ressources humaines, et la mutualisation de l’acquisition et du traitement des données de suivi des docteurs.
André de Richaud, un poète en revues
Authors: Simonelli Jacques 
Published: October 2021

Pourquoi proposer un itinéraire d’André de Richaud à travers revues et périodiques ? C’est que ses publications dans les supports les plus variés sont représentatives de l’ensemble de son œuvre – poésie, nouvelles, romans, théâtre, autobiographie et chroniques (qui révèlent un Richaud provocant, tendre et moqueur, paradoxal toujours). La courbe de ses contributions reflète les fluctuations de sa vie, des succès précoces des années trente à la floraison de nouvelles de l’immédiate après-guerre et aux années difficiles d’après 1950 où la nécessité l’oblige à multiplier les textes écrits à la hâte et à réutiliser des récits déjà publiés dans des périodiques de moins en moins prestigieux. Ses anciens amis se détournent ; ainsi Jean Ballard des Cahiers du Sud , déjà réticent devant ses « Marges » de 1952, lui refuse-il en 1953 des « Pages trouvées dans une poubelle » avant de rompre avec lui en 1960, par une lettre assez violente. Notre bibliographie, la plus complète à ce jour, n’est sûrement pas exhaustive. Nous espérons qu’elle suscitera de nouvelles découvertes.
El Cabeço de Mariola y las dinámicas complejas de la expansión romana (siglos II-I a. C.). Fortificaciones republicanas y reinterpretaciones locales en los oppida de Iberia oriental
Authors: Grau Mira Ignasi 
Published: October 2021

En este trabajo nos proponemos analizar las dinámicas complejas del proceso de expansión romana durante el periodo Ibérico Final, entre los siglos II-I a. C. en el área oriental de Iberia. La construcción de fortificaciones en oppida ibéricos se relacionaría con las estrategias de dominación romana de la región. Sin embargo, el proceso no fue ni lineal ni únicamente fruto de la imposición de los criterios de Roma, pues el papel de las poblaciones locales se mostró fundamental en estas dinámicas. Emplearemos la documentación reciente del Cabeço de Mariola, un oppidum ibérico del área central de la Contestania, contextualizado en las dinámicas regionales, para ofrecer los argumentos de complejas interacciones entre el poder romano y las poblaciones locales.
La fête baroque, archétype du macro-événement-spectacle
Authors: Spielmann Guy 
Published: October 2021

Le projet PerformArt vise à relancer l’étude des fêtes des cours européennes à l’époque baroque, longtemps axée sur la seule recherche archivistique, en interrogeant le concept même de performance, qui est devenu une coquille plus ou moins vide dans laquelle les chercheurs de toutes les disciplines projettent leurs propres préoccupations et leurs préjugés. La notion d’“événement-spectacle”, qui implique à la fois un agir performatif et un agir spectatif à un moment précis dans le temps et dans l’espace, ouvre des perspectives nouvelles pour la recherche sur les fêtes. Une approche fondée sur l’événement jette un éclairage entièrement nouveau sur le spectacle en tant que phénomène fondamental d’interaction sociale ; inversement, l’étude des fêtes de cour nous aide à mieux comprendre les événements-spectacles. En effet, la fête de cour, qui se situe à l’intersection de la politique, du divertissement, de l’économie, de l’esthétique et de l’interaction sociale, constitue une forme très complexe d’événement-spectacle.
Psychological Ownership in Athletic Training
Authors: Young Justin P. , Games Kenneth E. , Rivera Matthew J. , Eberman Lindsey E. 
Published: October 2021

Context
Psychological ownership (PO) is a state in which an individual feels possession over an object, organization, or entity (eg, PO over the organization where one works, PO over the profession one serves). Understanding PO could provide insight into the “vitality of the profession” as defined in the Prioritized Research Agenda for the Athletic Training Profession.

Objective
To explore athletic trainers' (ATs') PO over their employing organizations and the athletic training profession.

Design
Cross-sectional study.

Setting
Web-based survey.

Patients or Other Participants
Clinically practicing ATs who were active members of the National Athletic Trainers' Association.

Main Outcome Measure(s)
Demographic variables, Psychological Ownership Questionnaire (POQ) scores, and Psychological Ownership Questionnaire for athletic training (POQ-AT) scores were the primary outcomes measured. Descriptive statistics were calculated for the demographic variables, POQ and POQ-AT overall scores, form scores, and dimension scores. Nonparametric tests were used to investigate differences between the POQ and POQ-AT by demographic characteristics.

Results
The ATs indicated greater PO over the athletic training profession (Z = −3.45, P = .001) than over their employing organizations. They displayed greater belongingness (Z = −9.51, P &lt; .001) and self-identity (Z = −8.71, P &lt; .001) and less territoriality (Z = −5.52, P &lt; .001) and accountability (Z = −5.33, P &lt; .001) over their profession than their organization. Those ATs who supervised others had higher overall POQ (Mann-Whitney U test = 34 372, P &lt; .001) and overall POQ-AT (U = 36 624, P = .014) scores than ATs who did not supervise others. A difference was evident in overall POQ (Kruskal-Wallis statistical analysis H4 = 20.47, P &lt; .001) and overall POQ-AT (H4 = 21.34, P &lt; .001) scores by years of experience.

Conclusions
Respondents indicated greater PO over their profession than their employing organizations. They demonstrated greater self-identity and belongingness and less territoriality and accountability over the athletic training profession than over their employing organization, suggesting that they were connecting aspirations and accomplishments with the profession but connecting duty and responsibility with their organizations. Years of experience and supervisor status may play roles in the level of organizational PO.

Authors: Yeniocak Selman , Kalkan Asım , Yamanoğlu Adnan , Öztürk Semi , Söğüt Özgür , Metiner Merve 
Published: October 2021

OBJECTIVES:
Limited clinical studies have investigated the effects of synthetic cannabinoids (SCs) on the cardiovascular system (CVS). The aim of this study was to evaluate the effects of SCs on the CVS.

METHODS:
The patient group of this single-center, prospective, case–control study consisted of adult patients presenting to the emergency department (ED) with symptoms of SC use. Vital signs and electrocardiogram (ECG) after use of SC of patients were followed. A control group with a similar number of patients and patient demographics were formed following the patient admission process. Pulse rate, arterial blood pressure (ABP), and ECG of patient and control groups were compared using Mann–Whitney U and Chi-squared tests.

RESULTS:
A total of 148 people were included in the study, 74 in the patient group and 74 in the control group. Systolic and diastolic ABPs of patient group were statistically significantly lower than those of the control group (P < 0.001). P-wave width and amplitude in the patient group were significantly higher compared to the control group (P: 0.027 and P: 0.004, respectively). QRS width on patient group ECGs was significantly higher than in the control group, while T-wave amplitude was significantly lower (P: 0.045 and P < 0.001, respectively). ST elevation was seen in 12 (16.2%) subjects in the patient group, while no ST elevation was seen in the control group (P < 0.001).

CONCLUSION:
SCs can reduce systemic tension and SCs may cause changes in ECG, especially P wave, ST segment, T wave, and QRS. Further large-scale studies are needed to show whether these changes are associated with fatal arrhythmias or myocardial infarction.

Published: October 2021

Background:
Governments have imposed lockdowns in the wake of the COVID-19 pandemic. Hospitals have restricted outpatient clinics and elective services meant for non-COVID illnesses. This has led to patients facing unprecedented challenges and uncertainties. This study was carried out to assess patients’ concerns and apprehensions about the effect of the lockdown on their treatments.

Materials and Methods:
An ambispective, observational cross-sectional single centre study was conducted. Patients were contacted telephonically and requested to answer a structured questionnaire. Their responses were documented and summarized as frequency and proportions.

Results:
A total of 727 patients were interviewed. Epilepsy (32%) was the most common neurological illness in our cohort followed by stroke (18%). About half the patients and/or their caregivers reported health-related concerns during the lockdown. The primary concern was how to connect with their treating neurologist if need arose. Forty-seven patients (6.4%) had drug default. Among patients on immunomodulatory treatments, only eight patients had drug default. High compliance rates were also observed in the stroke and epilepsy cohorts. Of the 71 patients who required emergency care during the lockdown, 24 could reach our hospital emergency. Fourteen patients either had a delay or could not seek emergency care. Two-thirds of our patients found the telemedicine experience satisfactory.

Conclusion:
The ongoing pandemic will continue to pose challenges to both physicians and patients. Patients in follow-up may need to be contacted regularly and counselled regarding the importance of maintaining drug compliance. Telemedicine can be used to strengthen the healthcare delivery to patients with non-COVID illnesses.
Interleukin-2 gene expression and its relation to red blood cell indices and T lymphocytes in anemic Egyptian children
Authors: Maha Anani M. , Amani El-Kelani , Asmaa Hashem A. , Mona Salama I. 
Published: October 2021

Context
Iron-deficiency anemia (IDA) is a health problem affecting children, females, and the aged. Increased knowledge about the etiology and cytokines of IDA can aid early detection and management.

Aims
The objectives of this research to assess interleukin-2 (IL-2) gene expression by real-time PCR and examine its relation to red blood cell indices and T lymphocytes in IDA in children.

Settings and design
This was a case–control study. A total of 60 children was included, and two groups were identified: group 1 (latent iron-deficiency anemia) and group 2 (IDA). Moreover, 30 healthy children were included as a control group.

Patients and methods
Complete blood count, serum ferritin, and immunophenotyping of the T lymphocyte subtypes were performed.

Statistical analysis used
Statistical Package for Social Science (SPSS) for Windows (version 16.0) software program was used for statistical analysis.

Results
A total of 21 (70%) patients of IDA group showed a low IL-2 gene expression. There is a significant positive correlation between IL-2 gene expression and T lymphocyte cell count (CD3+), cytotoxic T lymphocyte cells count (CD3+CD8+), and mean fluorescence intensity of CD3+CD8+ cells.

Conclusions
There was a significant positive correlation between IL-2 gene expression and red blood cell count, mean corpuscular hemoglobin concentration, serum ferritin level, serum iron level, T lymphocyte cells count (CD3+), cytotoxic T lymphocyte cells count (CD3+CD8+), and mean fluorescence intensity of CD3+CD8+ cells.
Methylation status of galectin-12 gene promoter in acute myeloid leukemia
Authors: Helbawi Fatma M. , Ahmed Sohair M. , Mahmoud Maged S. , Assem Magda M. , Kamal Taghreed M. , Abdou Madleen Adel A. 
Published: October 2021

Intro
duction Acute myeloid leukemia (AML) is a hematopoietic stem cell disorder, characterized by a block in differentiation of hematopoiesis, which results in the growth of a clonal population of neoplastic cells or blasts. In a previous study, the expression profiling of cancer-related galectins in AML showed upregulated expression of galectin-12 leading to cell cycle arrest. This observation pointed to the possibility that galectin-12 in AML could be a tumor-suppressor gene and a potential prognostic marker.

Objective
The aim was to study the methylation status of galectin-12 gene promoter in AML and its correlation with the expression of the gene and its potential effect on overall survival of patients.

Patients and methods
This study was carried out on 28 newly diagnosed AML cases. Expression of gal-12 gene was detected by reverse transcriptase-PCR, and the methylation status was examined by bisulfite genomic sequencing.

Results
Our results showed that 23/28 (82.1%) cases were negative for mRNA expression. The same group (82.1%) showed hypermethylated CpG island in the promoter region of LGALS12.

Conclusion
There is an association between LGALS12 expression and promoter hypermethylation [refers to the addition of a methyl group (CH3) covalently to the base cytosine (C) in the dinucleotide 5[Combining Acute Accent]-CpG-3[Combining Acute Accent]]. The mean survival of patients with unmethylated LGALS12 gene is significantly higher than methylated gene.
Comparison of Illustrative Handouts and Self-Drawing on Learning Outcomes from Anatomy Lectures
Authors: Narayanan Suresh , Shankar Nachiket 
Published: October 2021

Background:
Illustrative handouts and self-drawing have been shown to improve learning outcomes from lectures. The objective of this study was to compare the test scores among students taught using these two methods in anatomy lectures and to assess the students' perceptions about the same.

Methodology:
This was a quasi-experimental pre- and post test study done among 1st-year medical undergraduates to evaluate the effectiveness of illustrated handouts. For two of the lectures (Group 1 lectures), students were asked to draw along with the teacher, while for the other two lectures (Group 2 lectures), they were given illustrative handouts and were required to progressively color and label. The multiple-choice questions were administered prior to the lectures and 4 months after completion of the lectures. The paired t-test, Wilcoxon signed-rank test, and Mann–Whitney U-test were used to estimate score differences. Students' perceptions were assessed using a questionnaire.

Results:
There was a significant improvement in post test scores for both handout and self-drawing sessions. The score improvement was significantly higher for the handout session when compared to the self-drawing session. No significant gender differences were noted. More than 80% of the students had positive opinions about all aspects of the handouts that were assessed.

Conclusion:
Supplementing lectures with illustrative handouts resulted in higher knowledge retention when compared to self-drawing. Students felt that illustrated handouts facilitated their learning from lectures.
