HACERSE VIRAL: LAS ACTIVIDADES ARTÍSTICAS Y SU RESPUESTA ANTE LOS RETOS QUE IMPONE LA TRANSFORMACIÓN DIGITAL
Authors: Pérez Ibáñez Marta
Published: March 2021

La cultura en general y, en concreto, la actividad desarrollada por museos, centros de arte y artistas, ha experimentado durante la última década profundos cambios en sus canales y estrategias de aproximación a la sociedad. La forma en que la transformación digital, común a toda nuestra sociedad, ha incidido en dicho sector no sólo ha permitido fortalecer la función social de los museos respecto de sus públicos, haciendo más accesible la creación artística, así como la conexión de los artistas independientes con la sociedad, sino que ha demostrado ser un elemento fundamental de cohesión social y de desarrollo cultural en época de confinamiento, aportando nuevas estrategias, canales y contenidos más sensibles y comprometidos, sostenibles, creativos, allí donde la presencialidad, imprescindible para el disfrute de la actividad cultural, se ha visto limitada.

EL IMPACTO DE LA INTELIGENCIA ARTIFICIAL EN LA SOCIEDAD
Authors: Gilsanz Muñoz María Asunción
Published: March 2021

Como impactarán las nuevas tecnologías en la sociedad en los próximos años o como podrá la Inteligencia Artificial ayudar a sectores como la economía o el medio ambiente es una pregunta que todos nos estamos haciendo.

La Inteligencia Artificial ya es parte de nuestro presente y será parte clave de nuestro futuro, pero ¿qué ha cambiado para que esto haya sido posible? La respuesta está en el avance que la tecnología ha tenido en los últimos años debido al incremento exponencial que han tenido tres factores clave, la potencia de procesamiento, el aumento de la velocidad en las comunicaciones y el abaratamiento del almacenamiento de datos, que han facilitado la innovación tecnológica.

Esta facilidad para la innovación tecnológica ha propinado que hoy en día el mercado está lleno de pequeñas empresas o startups que están aprovechando esta tecnología para desarrollar nuevos productos y soluciones que mejoren la vida de la sociedad y de las personas.

Peran Pengajian Halaqah Terhadap Peningkatan Pengetahuan Nahwu Santri Di Pondok Pesantren Al-Urwatul Wutsqaa
Authors: Zaitun Zaitun , Hasmulyadi Hasmulyadi
Published: March 2021

This research discusses the role of halaqah recitation in increasing nahwu knowledge of students at Al-Urwatul Wutsqaa Islamic Boarding School, Benteng Village, Sidrap Regency. The main problem being studied is the implementation of the halaqah recitation, the nahwu knowledge of students and the supporting and inhibiting factors of increasing the nahwu knowledge of students. This study aims to determine the process of implementing halaqah recitation, increasing nahwu knowledge, as well as supporting and inhibiting factors for increasing students' nahwu knowledge. This research is a qualitative descriptive study with an educational approach and a psychological approach. This type of this research is field research. Data collection techniques in this research using observation, interviews, and documentation. The results of this study indicate that the recitation of halaqah at Al-Urwatul Wutsqaa Islamic Boarding School plays an important role in increasing the knowledge of nahwu students. It is seen that students already know the position of words and are able to give vowels to every word contained in the book. Supporting factors for increasing nahwu knowledge with learning other than halaqah recitation, such as Arabic takhassus, Musabaqah Qira'atul Kutub, Arabic language villages and other extracurricular programs and books studied in halaqah recitation were tested on even and odd semester examinations. The inhibiting factor is from the lack of interest of some students, so they are less motivated in following the halaqah recitation process.

The Application of Ethnic Cultural Symbols in Modern Visual Communication Design
Authors: Zhang Xin
Published: March 2021

Visual communication design is based on visual perceived information, and conveys a certain value orientation or objective cognition through visual language, words, symbols, images, etc. In modern visual communication design, focus on and discover national cultural symbols to express national cultural spirit and artistic connotation, so as to better deepen the channels of multicultural integration and make up for the lack of culture in modern visual communication design. The strong symbolic meaning and regional color of the ethnic cultural symbols are the specific embodiment of the Chinese people’s inherited ideas, customs and culture, with distinctive artistic value and aesthetic experience. This paper combines the characteristics, connotation and classification of ethnic cultural symbols to explore their application value and specific application in visual communication design.
Research of Collection Arrangement of Gelao 's Genealogy
Authors: Song Hanrui
Published: March 2021

The Gelao nationality is one of the oldest minorities in southern China recognized by the academic circles. However, up to now, the genealogical research of Gelao nationality is still very weak. The reason is that the genealogical data of the Gelao nationality is extremely scarce at present, which seriously affects the development of relevant research. Therefore, it is urgent to collect and sort out the genealogy of the Gelao nationality in a comprehensive and systematic manner. The genealogy research of Gelao nationality will use the following methods: the combination of document acquisition method and field survey method; digital collection method; document cataloging method and summary method; content analysis and value analysis; intra-ethnic and inter-ethnic comparative analysis. The Gelao genealogy research has several academic values: it provides solid data support for related research in philology, ethnology, history, and other disciplines; it helps to expand the research scope and field of genealogy; it helps to promote the in-depth development of Gelao studies. The practical significance of the study of Gelao genealogy: it helps to promote family construction in Gelao areas; it helps to enhance the cultural confidence of Gelao people and maintain the harmony and stability of Gelao areas.

Published: March 2021

Annotation Purpose. Summarize the regulatory and technological requirements for the production of organic (organo-mineral) fertilizers on the base of sewage sludge. Methods. Analysis and generalization of the requirements of regulatory documents on the management of organic waste and their use as raw materials for the production of organic fertilizers and soil improvers. Results. The current legislative, departmental and regulatory documentary base in Ukraine concerning the treatment of sediment resulting from biological sewage treatment at municipal wastewater treatment plants for its further use in agriculture as fertilizers is analysed. Indicators are identified and analysed to determine the possibility, feasibility, efficiency and scope of organic fertilizers produced using sewage sludge. The analysis of changes in the content of organic matter and total nitrogen in the sewage sludge during its storage at the sewage treatment plant sites is presented. The technological feasibility of using sludge of different shelf life in composting production has been determined. Conclusions 1. The regulatory framework of Ukraine contains a sufficiently complete list of indicators that should be met by organic raw materials (sewage sludge) for further use as organic fertilizers. Some of these indicators – bio security and heavy metals content – can be improved in the composting process of fertilizers. 2. Fresh sediment, as well as sediment accumulated in the last late autumn and winter periods, is of main value for use as a raw material in the production of organic fertilizers. 3. The use in the production of compost sludge stored on sludge sites for a period of half a year or more requires special control of the process of decontamination. In this case, it is advisable to use additional means of wastewater decontamination. Keywords: heavy metals, manure, humus, decontamination, composting, organic fertilizers, sewage sludge.

Directionality eclipses agency: How both directional and social cues improve spatial perspective taking
Authors: Gunalp Peri , Chrastil Elizabeth R. , Hegarty Mary
Published: March 2021

Research on spatial perspective taking has suggested that including an agent in the display benefits performance. However, little research has examined the mechanisms underlying this benefit. Here, we examine how an agent benefits performance by examining its effects on three mental steps in a perspective-taking task: (1) imagining oneself at a location (station point) within in the array, (2) adopting a different perspective (heading), and (3) pointing to an object from that perspective. We also examine whether a non-agentive directional cue (an arrow) is sufficient to improve performance in an abstract map-like display. We compared a non-directional cue to two cues for position and orientation: a human figure (agentive, directional) and an arrow (non-agentive, directional). To examine the effects of cues on steps 2 and 3 of the perspective-taking process, magnitude of the initial perspective shift and pointing direction were varied across trials. Response time and error increased with the magnitude of the imagined perspective shift and pointing to the front was more accurate than pointing to the side, or back, but these effects were independent of directional cue. A directional cue alone was sufficient to improve performance relative to control, and agency did not provide additional benefit. The results overall indicate that most people adopt an embodied cognition strategy to perform this task and directional cues facilitate the first step of the perspective-taking process, imagining oneself at a location within in the array.
Predicting as a learning strategy
Authors: Brod Garvin
Published: March 2021

This article attempts to delineate the procedural and mechanistic characteristics of predicting as a learning strategy. While asking students to generate a prediction before presenting the correct answer has long been a popular learning strategy, the exact mechanisms by which it improves learning are only beginning to be unraveled. Moreover, predicting shares many features with other retrieval-based learning strategies (e.g., practice testing, pretesting, guessing), which begs the question of whether there is more to it than getting students to engage in active retrieval. I argue that active retrieval as such does not suffice to explain beneficial effects of predicting. Rather, the effectiveness of predicting is also linked to changes in the way the ensuing feedback is processed. Initial evidence suggests that predicting boosts surprise about unexpected answers, which leads to enhanced attention to the correct answer and strengthens its encoding. I propose that it is this affective aspect of predicting that sets it apart from other retrieval-based learning strategies, particularly from guessing. Predicting should thus be considered as a learning strategy in its own right. Studying its unique effects on student learning promises to bring together research on formal models of learning from prediction error, epistemic emotions, and instructional design.

Published: March 2021

Minyak atsiri dapat dijumpai di berbagai jenis tanaman yang tersebar di seluruh dunia. Indonesia setidaknya memiliki 40 jenis tanaman penghasil minyak atsiri komersial. Minyak atsiri memiliki berbagai manfaat, yaitu sebagai bahan baku kosmetik, obat-obatan, parfum, lilin, dan flavor. Salah satu atsiri yang diproduksi di Indonesia adalah citronella oil, citronella oil termasuk salah satu jenis atsiri yang populer digunakan sebagai anti-nyamuk, anti-jamur, dan anti-oksidan. Meskipun di Indonesia sudah berkembang luas petani yang berkebun serai wangi dan mengolahnya hingga menghasilkan minyak, akan tetapi masih banyak di antara mereka yang memproduksi citronella oil yang belum memenuhi standar. Oleh sebab itu, perlu adanya kajian mengenai faktor-faktor yang mempengaruhi kualitas citronella oil yang dihasilkan oleh usaha perseorangan agar dapat memenuhi standar industri. Untuk mengetahui kandungan citronella oil, dilakukan pengujian GC-MS. Hasil penelitian menunjukkan bahwa citronella oil yang dihasilkan memiliki kadar sitronellal yang lebih rendah dibandingkan industri besar, yaitu 11.37%. Sedangkan standar minimal untuk sitronelal adalah 35%, hal ini diduga berkaitan dengan umur panen, kualitas tempat tumbuh, kualitas mesin, dan pretreatment.

Spectroscopic and Photometric Monitoring of a Poorly Known Highly Luminous OH/IR Star: IRAS 18278+0931
Authors: Ghosh Supriyo , Mondal Soumen , Das Ramkrishna , Dutta Somnath
Published: March 2021

We present the time-dependent properties of a poorly known OH/IR star, IRAS 18278+0931 (hereafter IRAS 18+09), toward the Ophiuchus constellation. We have carried out long-term optical/near-infrared photometric and spectroscopic observations to study the object. From optical R- and I-band light curves, the period of IRAS 18+09 is estimated to be 575 ± 30 days and the variability amplitudes range from ΔR ∼ 4.0 mag to ΔI ∼ 3.5 mag. From the standard period–luminosity relations, the distance (D) to the object, 4.0 ± 1.3 kpc, is estimated. Applying this distance in the radiative transfer model, the spectral energy distribution is constructed from multiwavelength photometric and IRAS-LRS spectral data, which provide the luminosity, optical depth, and gas mass-loss rate of the object to be 9600 ± 500 L
⊙, 9.1 ± 0.6 at 0.55 μm, and 1.0 × 10−6
M
⊙ yr−1, respectively. The current mass of the object is inferred to be in the range 1.0−1.5 M
⊙ assuming solar metallicity. Notably, the temporal variation of atomic and molecular features (e.g., TiO, Na i, Ca i, CO, H2O) over the pulsation cycle of the OH/IR star illustrates the sensitivity of the spectral features to the dynamical atmosphere as observed in pulsating AGB stars.
Nonlinear Damping of Standing Kink Waves Computed With Elsässer Variables
Authors: Van Doorsselaere Tom , Goossens Marcel , Magyar Norbert , Ruderman Michael S. , Ismayilli Rajab
Published: March 2021

In a previous paper, we computed the energy density and the nonlinear energy cascade rate for transverse kink waves using Elsässer variables. In this paper, we focus on the standing kink waves, which are impulsively excited in coronal loops by external perturbations. We present an analytical calculation to compute the damping time due to the nonlinear development of the Kelvin–Helmholtz instability. The main result is that the damping time is inversely proportional to the oscillation amplitude. We compare the damping times from our formula with the results of numerical simulations and observations. In both cases we find a reasonably good match. The comparison with the simulations shows that the nonlinear damping dominates in the high amplitude regime, while the low amplitude regime shows damping by resonant absorption. In the comparison with the observations, we find a power law inversely proportional to the amplitude η
−1 as an outer envelope for our Monte Carlo data points.

Authors: Pop Jordanova Nada , Ristova Jovanka , Loleska Sofija
Published: March 2021

Ophthalmological problems have a great influence on the quality of life, employment and everyday activities. In this context they are an important issue in the public health. The aim of this study was to evaluate the level of anxiety, depression as well as type-A personality in a sample of 40 ophthalmological patients. The results obtained showed moderate anxiety, moderate depression, as well as different type of personality related to the diagnosis. Scores obtained for psychometric tests are related to the age, but not to the gender. Research confirmed that depressive symptoms and anxiety may not only aggravate symptoms of eye disease, but also affect other psychological systems forming a vicious circle. With a change of the medical model, medical professionals are placing an increasing emphasis on the mental health of patients. It is an imperative to introduce social measures for improvement of the health. These findings highlight an important mental health issue in eye disease patients.
Epidemiological aspects of carotid disease
Authors: Paljoskovska-Jordanova Savetka
Published: March 2021

Carotid artery disease most commonly manifests as atherosclerotic carotid artery disease, which can lead to an ischemic stroke. Our aim was to present the epidemiological aspects of carotid disease and to demonstrate the association of risk factors with carotid disease. For that purpose, we prospectively followed 1031 patients at the University Clinic for Cardiology in Skopje, who were examined for carotid stenosis and its correlation with risk factors such as hypertension, smoking, hyperlipidemia, diabetes, obesity and peripheral arterial disease. Results: Carotid stenosis was correlated with arterial hypertension, hyperlipidemia, diabetes mellitus, smoking, and peripheral arterial disease. Conclusions: Our study found that conventional risk factors such as hypertension, diabetes, smoking, and dyslipidemia were independently associated with significant carotid artery disease and peripheral arterial disease.

La covid-19, facteur de recompositions géopolitiques
Authors: Dumont Gérard-François
Published: March 2021

Pendant ses premiers mois, au début de l’année 2020, la survenue de l’épidémie de la Covid-19 n’a essentiellement été considérée que dans ses dimensions sanitaires. Puis les aspects économiques se sont rapidement révélés essentiels. L’arrivée annoncée de vaccins a été souvent présentée comme une merveilleuse occasion d’une solidarité planétaire de pays se tenant par la main, permettant le bannissement de toute idée de rapports de force géopolitiques entre les États. Mais il n’en a rien été. La Covid-19 ne serait-elle devenue un fort objet géopolitique ? N’aurait-elle pas entraîné d’importantes recompositions géopolitiques ?
Une épidémie peut en cacher une autre : personnes exposées au VIH et crise du Covid-19
Authors: Izambert Caroline , Thibeaud Matthias , Maria Alicia
Published: March 2021

L’association AIDES fait le constat que l’épidémie de Covid-19 a été un facteur aggravant des discriminations déjà existantes. À partir d’une campagne importante de recueil de témoignages, l’association de lutte contre le VIH et les hépatites montre comment les situations déjà très précaires des travailleur·ses du sexe, des personnes vivant avec le VIH, des usager·es de drogues, des personnes étrangères en situation administrative précaire, des détenu·es ont empiré du fait du confinement et de la rétractation des services publics. Loin de faire un simple constat, l’association souligne qu’il y a beaucoup à apprendre de l’expérience des associations de malades et personnes concernées qui se sont engagées depuis longtemps dans le développement de pratiques de réduction des risques et d’autosupport à l’heure où l’épidémie s’installe dans la longue durée.

Published: March 2021

Audrey Mariette et Laure Pitti mènent depuis 2013 une enquête sur les « politiques, professionnel·les et pratiques de santé en territoire populaire » en Seine-Saint-Denis. Ce travail a pris une nouvelle dimension avec l’épidémie de Covid-19 qui est venue renforcer les inégalités existantes alors qu’une grande partie de la population était, par son emploi, ses conditions de vie et son état de santé surexposée au virus et aux formes graves de la maladie. Les discriminations dans l’accès aux soins, notamment celles subies par les personnes racisées, ont été exacerbées. Cependant, cette crise a également souligné les capacités d’organisation et de mobilisation des professionnel·les de santé en dépit du manque de moyens chronique.
La réponse communautaire à la pandémie de Covid-19 au Sénégal : un rendez-vous manqué ?

Published: March 2021

Au Sénégal, nombre d’acteurs et actrices de la santé communautaire se sont engagé·es précocement dans la lutte contre la Covid-19. Leurs réponses, conçues à partir des besoins des populations et des possibilités sur le terrain, se sont inspirées de ce qui avait fonctionné contre d’autres épidémies, comme celle du VIH ou celle du virus Ebola. Malgré leur efficacité, ces initiatives ont été entravées à la fois par les cadres du gouvernement sénégalais et ceux issus des institutions de santé globale. Une situation exemplaire des limites de la démocratie sanitaire en contexte de crise épidémique.

À la croisée des chemins ? Si l’expression n’était pas si galvaudée parce qu’employée lors de chaque crise que l’Union européenne a traversée depuis un demi-siècle, on pourrait l’utiliser une fois encore au vu de la situation créée par l’arrêt brutal de l’économie décidé par tous les gouvernements face à la pandémie du coronavirus. Depuis près d’un an, tout ce qui était considéré comme impossible est devenu monnaie courante (comme on le verra plus loin, on ne trouvera jamais une expression aussi appropriée !). Tous les dogmes que l’on pensait quasi perpétuellement installés ont été bousculés, voire remis au placard. Les plus orthodoxes des économistes libéraux·ales, les gardien·nes les plus sourcilleux·euses de l’indépendance des banques centrales, les gouvernements les plus stricts en matière de rigueur budgétaire, tou·tes ont lâché du lest, certain·es ont même viré de bord. Jean-Marie Harribey et Esther Jeffers examinent, dans ce qui suit, le plan de relance de l’Union européenne et le rôle qu’y joue la Banque centrale européenne (BCE) ainsi que son inscription dans un changement de modèle économique autour d’un « Green Deal ». Dans les deux cas, entre les affichages de communication et la mise en œuvre d’une transition socio-écologique il y a encore une grande distance… sociale.

The Paradoxes of Democratic Voting and the Peircean Justification of Democracy
Authors: Ottonelli Valeria
Published: March 2021

La défense peircienne de la démocratie propose de fonder l’attrait du gouvernement démocratique sur des intérêts épistémiques universels que nous partageons en tant qu’agents épistémiques individuels. Le problème avec cette approche est qu’elle se heurte à la manière caractéristique dont la délibération et la prise de décision démocratique socialisent notre savoir et nos croyances. L’approche peircienne méconnaît que ce trait caractéristique distingue la démocratie comme un jeu épistémique fondamentalement à part des jeux dans lesquelles nous nous situons, en tant qu’agents épistémiques, dans des contextes non-politiques et non-démocratiques. Les défauts de la défense peircienne se manifestent quand celle-ci fait face aux paradoxes du vote démocratique qui, pour être surmontés, demandent une conceptualisation profondément collectivisée et socialisée des processus démocratiques de la délibération et de la formation des opinions. Pour cette raison, la méconnaissance de la manière distinctive dont la délibération et la prise de décision démocratique socialisent le savoir pose problème à deux titres : premièrement, en basant la défense peircienne de la démocratie sure une conception inadéquate de l’épistémologie démocratique ; deuxièmement, en privant l’approche peircienne de sa capacité de répondre aux défis des paradoxes du vote.
Thymos . Circulation et appropriations conservatrices d'un concept platonicien, de Leo Strauss à l'Alternative für Deutschland
Authors: Quelennec Bruno
Published: March 2021

S’inscrivant dans le cadre des nouvelles recherches françaises en histoire sociale des idées politiques, cet article propose de reconstruire la carrière du concept platonicien de thymos dans l’histoire intellectuelle des 20e et 21e siècles en examinant sa circulation et ses appropriations variées, ainsi que les différents contextes dans lesquels il a été mobilisé. Après avoir restitué son émergence dans les textes des années 1930 du jeune Leo Strauss, on s’intéresse aux modalités de son implantation outre-Altantique chez les Straussians néoconservateurs (Allan Bloom et Francis Fukuyama), avant d’examiner sa réimportation dans l’Allemagne contemporaine (avec le philosophe Peter Sloterdijk et son étudiant, l’intellectuel de l’Alternative für Deutschland, Marc Jongen). L’article montre que le schème argumentatif du thymos garde une certaine stabilité dans le temps malgré la diversité de ses appropriations : il se caractérise ainsi toujours par une double charge normative qui exprime une ambivalence toute conservatrice à l’égard de l’ordre (libéral) établi, oscillant entre sa défense (protection du statu quo) et sa subversion ou radicalisation « par la droite ». L’article révèle également que le concept n’est pas uniquement mobilisé dans la lutte idéologique, mais aussi dans des luttes entre intellectuels : l’« ardeur », le « désir de reconnaissance » ou la « colère » que dénote la notion ont souvent chez les différents intellectuels étudiés aussi pour fonction d’exprimer une « révolte » de l’intellectuel conservateur face à son statut de « dominé » dans les champs intellectuels ou universitaires, positions qui contrastent souvent avec son rayonnement relatif dans d’autres champs.
D’un enjeu politique à un problème personnel
Authors: Ponge Rémy
Published: March 2021

Résumé Cet article s’inscrit dans une démarche de sociologie de l’action publique qui vise à comprendre le traitement d’un problème social en analysant les « luttes définitionnelles » que se livrent les acteurs en prise avec ce problème, dans les arènes publiques (médias, parlement), mais aussi dans des endroits plus discrets, à l’image des espaces paritaires de gestion des risques professionnels. S’appuyant sur un corpus d’archives et d’entretiens, il analyse les luttes politiques et syndicales du début des années 2000 au sujet de la reconnaissance en maladie professionnelle des souffrances psychiques (stress, risques psychosociaux, etc.). En articulant l’analyse de trois arènes (scientifique, politique, administrative et paritaire) qui ont participé à la politisation et à la définition de ces souffrances, nous montrons que leur reconnaissance s’est heurtée aux contraintes structurelles du système paritaire de gestion des risques professionnels ainsi qu’à l’indécision de l’État. En s’appuyant sur le produit des négociations entre organisations syndicales et patronales, le ministère du Travail a contribué à reproduire les inégalités sociales entre ces deux groupes d’acteurs participant, dans une certaine mesure, à l’individualisation de la réparation de ces maux. Cet article éclaire ainsi les processus qui contribuent à dépolitiser les dégâts sanitaires du travail et à en faire des problèmes personnels.
L’évolution du partage au sein d’une équipe de football en formation : une étude longitudinale
Authors: Kerivel Thibault , Bossard Cyril , Feigean Mathieu , Kermarrec Gilles
Published: March 2021

L’objectif de cette étude est d’analyser la construction du partage au cours de la formation de jeunes footballeurs professionnels. Si l’identification des contenus partagés au sein d’équipes expertes est un objet de recherche bien documenté au sein du courant de la Team Cognition dans des équipes militaires, professionnelles ou sportives, peu d’études se sont intéressées à la construction du partage au sein d’équipe au cours d’une formation. L’approche théorique de la conscience collective de la situation a été mobilisée ici pour décrire l’évolution des contenus partagés au sein d’un collectif issu d’un centre de formation de football professionnel sur un empan temporel de 10 mois. Des données comportementales complétées par des données verbales, collectées lors d’entretiens d’auto-confrontation, sont recueillies et analysées en 4 étapes. Les résultats permettent de mettre en avant : (1) les contenus partagés pendant la formation, (2) l’évolution du taux des éléments partagés au cours de la formation et (3) l’évolution des contenus des connaissances partagées en cours de formation. Les résultats de cette étude sont discutés selon trois axes : (1) l’évolution du partage et la diminution des éléments « stables », (2) le partage de connaissances focalisées sur des éléments externes à l’équipe et (3) les apports méthodologiques pour l’étude de la conscience collective de la situation dans une perspective longitudinale.
Construction of unique mild solution and continuity of solution for the small initial data to 1-D Keller-Segel system
Authors: Yahagi Yumi
Published: March 2021

In this paper, a one-dimensional Keller-Segel system of parabolic-parabolic type which is defined on the bounded interval with the Dirichlet boundary condition is considered. Under the assumption that initial data is sufficiently small, a unique mild solution to the system is constructed and the continuity of solution for the initial data is shown, by using an argument of successive approximations.
Creative Digital Writing
Authors: Hancı-Azizoglu Eda Başak , Kavaklı Nurdan
Published: March 2021

Second language writers can adapt their creative skills to acquire and reflect new knowledge with fewer sophisticated words through more contextual and inclusive language. This process is called using the poetic function of language in a second language. One way to achieve teaching the poetic function of language as part of creative writing activities to second language learners is modeling digital writing in creative and innovative forms. This research study contextualizes a digital, innovative, and culturally sensitive language learning model that will enhance digital natives' learning experience through creative digital writing practices.
Developing Robots, Self-Esteem, and Self-Perception for Elementary Students Through Educational Robotics
Authors: Eteokleous Nikleia
Published: March 2021

In this chapter, the impact of an educational robotics curriculum to enhance students' self-esteem and self-perception was examined. The intervention employed various activities and educational robotics packages based on the educational robotics curriculum developed by Frederick University Robotics Academy. Forty-one students, 6-13 years old, participated in a summer school program of 8 weeks. The study statistically examined the relationship between the robotics and the development of the aforementioned skills. The results revealed the positive impact and great potential of integrating robotics as a cognitive-learning tool to enhance self-esteem and self-perception of students. Specifically, the intervention minimized gender differences in self-esteem and revealed positive inference in both self-esteem and self-perception, with the last one to have also statistical significant differences. Finally, it revealed positive influences in regards to leaning, friendship, happiness, perception and acceptance of themselves, and expression of their beliefs and opinions.
Courageous Leadership
Authors: Pelonis Peggy
Published: March 2021

The chapter addresses leadership in educational institutions. Leading a diverse group of people towards a common vision can be both exhilarating and risky and thus requires courage. Courageous leadership embraces human imperfection while emphasizing self-reflection tracked via the personal leadership thread which ultimately leads to authentic leadership. The chapter further defines the fractal approach which strongly emphasizes the idea of leadership as a partnership consisting of a clear definition of leaders and learners and comprised of the following pillars: reflective practitioners, communities of belonging, innovation, and conscious citizenship. This approach ultimately leads to empowering individuals to be architects of their own learning who are committed to ethical decision making in order to improve life and living on the planet.
The Effectiveness of the i2Flex Methodology and the CoI in Addressing Complex Instructional Design Needs in High School Language Classes
Authors: Fyrigou Tonia
Published: March 2021

In this chapter, the goal is to describe the effectiveness of the implementation of the i2Flex in two different courses in the past five consecutive academic years in an attempt to meet more effectively the educational needs of the new educational framework. Starting with the description of the i2Flex methodology in a Greek class and in an online French class, the author presents the instructional (re-)design of the Moodle shell to reflect the new teaching methodology, and the need to evaluate this via an appropriate framework. It is obvious that the goal is to share under the umbrella of best practices how meaningful and efficient the i2Flex is in two different educational frames. At the same time, the use of community of inquiry (CoI) is taken in consideration to evaluate this educational process. Finally, the new role of the teacher, face to face and virtually, is observed to prove the progress of the educational environment.
A Differentiated Approach to Mathematics
Authors: Andrikopoulos Dora , Katsiyianni Matina
Published: March 2021

How can classroom teachers maximize the learning potential of their students? How can teachers, at the same time, attend to their students' differences? Students' readiness, interests, and learning profiles are the main targets for successful and meaningful learning. This chapter discusses all the above-mentioned characteristics of learners and focuses on the different approaches and instructional models in a Mathematics classroom. Having in mind a flexible learning framework that accommodates the needs of today's learners, the authors discuss and present applicable classroom instructional techniques, techniques that offer unique opportunities to fully amalgamate pedagogy by modifying learning experiences in the three areas of content, process, and product. The reader of this chapter will also get the chance to be exposed to the i2Flex methodology, which is a type of blended learning and has been born and developed at ACS Athens, Greece.
