On the multi-decadal oscillation of Atlantic tropical storm activity
Authors: Andronache Constantin , Suciu Nicolae , Vamoş Călin
Published: October 2023

Long term Atlantic tropical storm activity is described by the time series of the yearly Accumulated Cyclone Energy (ACE) Index for the time interval 1851-2007. ACE is a measure of total wind energy for North Atlantic basin and land falling tropical cyclone activity. Since the ACE index reflects a combination of storm intensity and duration it is a better measure of overall activity and likely damage than the number of either basin or land falling tropical storms or hurricanes. The yearly ACE time series is non-stationary, and one step toward detecting possible long-term quasi-periods is to detrend the original data. In this paper we use a procedure for data transformation by which ACE index is fitted in least square sense with polynomials of increasing order, followed by detrend. It is shown that, with some approximation, the obtained time series is cyclostationary, and a multi-decadal oscillation is detectable, as indicated by the power spectrum analysis.
A simple proof of Popoviciu's inequality
Authors: Bencze Mihaly , Popovici Florin
Published: October 2023

T. Popoviciu [5] has proved in 1965 the following inequality relating the values of a convex function \(f:I\rightarrow\mathbb{R}\) at the weighted arithmetic means of the subfamilies of a given family of points \(x_{1},...,x_{n}\in I\):\begin{align*}& \sum\limits_{1\leq i_{1}<\cdots <i_{p}\leq n}(\lambda_{i_{1}}+\cdots +\lambda _{i_{p}})\,f\left( \tfrac{\lambda_{i_{1}}x_{i_{1}}+\cdots +\lambda_{i_{p}}x_{i_{p}}}{\lambda _{i_{1}}+\cdots +\lambda _{i_{p}}}\right) \\& \leq \tbinom{n-2}{p-2}\left[\tfrac{n-p}{p-1}\,\sum\limits_{i=1}^{n}\,\lambda_{i}\,f(x_{i})+\left( \sum\limits_{i=1}^{n}\,\lambda _{i}\right) \,f\left( \tfrac{\lambda _{1}x_{1}+\cdots +\lambda _{n}x_{n}}{\lambda _{1}+\cdots+\lambda _{n}}\right) \right] .\end{align*}Here \(n\geq 3,\) \(p\in \{2,...,n-1\}\) and \(\lambda _{1},...,\lambda_{n}\) are positive numbers (representing weights). The aim of this paper is to give a simple argument based on mathematical induction and a majorization lemma.

Itô equation model for dispersion of solutes in heterogeneous media
Authors: Suciu N. , Vamoş C. , Vereecken H. , Sabelfeld K. , Knabner P.
Published: October 2023

Transport processes in heterogeneous media such as ionized plasmas, natural porous media, and turbulent atmosphere are often modeled as diffusion processes in random velocity fields. Using the Itô formalism, we decompose the second spatial moments of the concentration and the equivalent effective dispersion coefficients in terms corresponding to various physical factors which influence the transport. We explicitly define "ergodic'' dispersion coefficients, independent of the initial conditions and completely determined by local dispersion coefficients and velocity correlations. Ergodic coefficients govern an upscaled process which describes the transport at large tine-space scales. The non-ergodic behavior at finite times shown by numerical experiments for large initial plumes is explained by "memory terms'' accounting for correlations between initial positions and velocity fluctuations on the trajectories of the solute molecules.

On lower semicontinuity of the restricted center multifunction
Authors: Pai Devidas
Published: October 2023

Given a finite dimensional subspace \(V\) and a certain family \({\mathcal F}\) of nonempty closed and bounded subsets of \( {\mathcal C}_0(T,U)\), where \(T\) is a locally compact Hausdorff space and \(U\) is a strictly convex Banach space, we investigate here lower semicontinuity of the restricted center multifunction \(C_{V}:{\mathcal F} \rightrightarrows V.\) In particular, we establish a Haar-like intrinsic characterization of finite dimensional subspaces \(V\) of \({\mathcal C}_0(T,U)\) which yields lower semicontinuity of \(C_{V}.\)
The Kantorovich form of some extensions for the Szász-Mirakjan operators
Authors: Bărbosu Dan , Pop Ovidiu T. , Miclăuş Dan
Published: October 2023

Recently, C. Mortici defined a class of linear and positive operators depending on a certain function \(\varphi\). These operators generalize the well known Szász-Mirakjan operators. A convergence theorem for the defined sequence by the mentioned operators was given.Other interesting approximation properties of these generalized Szász-Mirakjan operators and also their bivariate form were obtained by D. Bărbosu, O. T. Pop and D. Miclăuș.In the present paper we are dealing with the Kantorovich form of the generalized Szász-Mirakjan operators. We construct the Kantorovich associated operators and then we establish a convergence theorem for the defined operators. The degree of approximation is expressed in terms of the modulus of continuity. Next, we construct the bivariate and respectively the GBS corresponding operators and we establish some of their approximation properties.
On the acceleration of the convergence of certain iterative proceedings (II)
Authors: Diaconu Adrian
Published: October 2023

The research reflected in this paper has its origin in the study of the convergence of the sequences generated through the use of certain methods derived from the well-known Newton-Kantorovich method for the approximation of the solution of an equation in a linear normed space, together with the inverse of the Fréchet differential on this solution. An important place is given in the paper to the notion of convergence speed order of an approximant sequence of the solution of an equation. Considering given an approximant sequence which verifies certain conditions expressed through the inequalities (25), we will build another approximant sequence through the relations (22), sequence which finds its convergence speed order ameliorated. We will analyze certain special cases and, in the same time, we will determine optimal methods from the point of view of the convergence speed order.
Positive semi-definite matrices, exponential convexity for multiplicative majorization and related means of Cauchy's type
Authors: Latif Naveed , Pečarić Josip
Published: October 2023

In this paper, we obtain new results concerning the generalizations of additive and multiplicative majorizations by means of exponential convexity. We prove positive semi-definiteness of matrices generated by differences deduced from majorization type results which implies exponential convexity and \(\log\)-convexity of these differences and also obtain Lyapunov's and Dresher's inequalities for these differences. We give some applications of additive and multiplicative majorizations. In addition, we introduce new means of Cauchy's type and establish their monotonicity.

L’église Saint-Martin de Purgerot. Un édifice du premier art gothique cistercien dans le comté de Bourgogne
Authors: Dard-morel Ghislaine
Published: October 2023

Situé dans le nord du comté de Bourgogne (actuelle Franche-Comté) le village de Purgerot se trouva très vite sous la dépendance de l’abbaye cistercienne de Cherlieu. Le dépouillement des sources écrites a permis la restitution du parti primitif de l’église Saint-Martin. L’analyse du monument en a précisé les caractères cisterciens et a permis de lier la construction à celle de l’abbatiale de Cherlieu, dans le troisième quart du XIIe siècle. Avec un décalage chronologique dû à son éloignement de la région d’origine du nouvel art de bâtir, l’église Saint-Martin présente les caractéristiques de l’art gothique débutant, introduit par les moines blancs dont l’expansion dans cette région de marche fut à cette époque particulièrement dynamique et dont l’interprétation épurée du gothique devait influencer la construction des nombreuses églises paroissiales de la région.
Les demeures urbaines médiévales en France : les fruits d’un renouvellement du regard (1995-2020)

Résumés Medieval urban dwellings in France : a harvest of renewed observation (1995-2020), by Pierre Garrigou Grandchamp

Among all the areas of research bearing on medieval architecture, the subject of urban domestic architecture in the 11th-15th centuries is undeniably one of those that has undergone a most remarkable development in the last decades, both in the diversity of themes treated and the abundance of scholarly production. These contributions, however, are in part little known, as they appear in regional journals or in the “ grey literature” of academia, made up of studies that are not always easily accessible. Consequently, the present publication has reserved an especially large place for them in the copious bibliography of 730 titles that brings the article to a close. This article echoes the one published by Yves Esquieu twenty-five years ago in the Bulletin monumental. It deals first with the underestimated importance of the corpus of medieval houses, then the nature of the first known dwellings (between the 5th and 11th century), the different ways and means of occupying land between the 11th and 14th century, the architectural programs and types that developed, building practices (including the materials used), and finally the “ outside and inside” of the residences (composition of the façades and arrangement of the interiors).
Après l’incendie. Notre-Dame de Paris : bilan, réflexions, perspectives
Authors: Gallet Yves
Published: October 2023

The conflagration on 15 April 2019 was the worst catastrophe suffered by the Cathedral of Notre-Dame de Paris since its construction in the twelfth century. Because of the immense fame of the monument, the emotion shook the planet. Commentaries and rumors proliferated, sometimes to the detriment of properly verified information, and all this well before the results of the police inquest into the causes, the extent of the damage, and the state of the monument were rendered public, as well as the place of the cathedral in the history of Gothic art and the range of solutions possible for the replacement of the timberwork, etc. It has been deemed essential that for the readers of the Bulletin monumental a judicious state of the question be given concerning what was destroyed by the fire, the current state of the masonry, and the perspectives and challenges that face both those responsible for the reconstruction and scholars who will deal with the cathedral in the future.

Évolution de la flore et de la végétation du lac de Creno (Corse) vingt-cinq ans après la mise en place de mesures de gestion
Authors: Paradis Guilhan , Piazza Carole , Sorba Laurent
Published: October 2023

La dépression occupée par le lac de Creno (Corse) résulte d’un surcreusement lors du maximum glaciaire würmien. Pour réduire les impacts dus aux animaux et aux visiteurs, plusieurs aménagements ont été réalisés en 1991 et 1996 (clôtures, gardiennage, obstruction de l’exutoire par un petit barrage). La végétation, décrite par des relevés phytosociologiques et une phytocartographie, comprend en 2019-2020 : (1) une cariçaie-nardaie de bordure sur un substrat minéral, (2) des pozzines à Drosera rotundifolia, (3) une pelouse à Potentilla anglica subsp. nesogenes et Drosera rotundifolia sur d’anciennes tourbières en îlots flottants, (4) un groupement de recolonisation des portions anciennement dénudées par les animaux, à Poa supina et Juncus conglomeratus, (5) une roselière à Phragmites australis, (6) deux peuplements de Nymphaea introduits et en expansion, (7) trois groupements hydrophytiques [(i) à Glyceria notata, (ii) à Lythrum portula et Juncus bulbosus et (iii) à Juncus bulbosus et Ranunculus flammula]. Parmi les actions de sauvegarde menées, un petit barrage, mis en place en 1996, maintient longtemps en été un haut niveau de l’eau, ce qui, sur les pozzines des pourtours du lac, a favorisé la multiplication de Drosera rotundifolia, au nombre de plus de 3500 individus en 2020, contre 130 en 1992.

La buxaie des Maâdhid (Algérie) : une irradiation biogéographique euro-méditerranéenne aux confins saharo-méditerranéens
Authors: Abdelkader Benkheira , Hamadene Samia , Ouadah Nadia , Kaabeche Mohamed
Published: October 2023

Boxwood (Buxus sempervirens L.) has an exceptional presence in Algeria by its rarity and its distribution. Moreover, species location in the Saharo-Mediterranean borders makes its study of a special interest. Paradoxically, this species, belonging in the list of protected plants, has not yet been sufficiently investigated in the ecological and floristic field. To fill this gap in the knowledge of the floral heritage of Algeria, both from an ecological and phytogeographic point of view, a series of successive observations was carried out, for the first time, during the summer and autumn 2017 and winter and spring 2018 in the djebel Maâdhid, in order to identify distribution area, understand dynamic evolution, and determine the conservation status of Buxus populations. Two methodological approaches were carried out in different habitats : a phytoecological approach according to altitudinal sequence of the vegetation (toposequence) and a phytogeographic approach to specify the position of the buxaie within this sequence. The results underline the oromediterranean character of Buxus sempervirens community, which extends along a toposequence from 1,000 m to 1,864 m.

Les argentei de type « parisien », étude d’un monnayage d’argent régional de la fin du VIe et du début du VIIe siècle
Authors: Foucray Bruno , Blanchet Guillaume , Sarah Guillaume
Published: October 2023

The identification of an original argentei coinage issued in Paris and other mints from the north of the Ile-de-France at the very end of the 6th century is a novelty. Fifteen specimens from archaeological excavations were studied and benefited of a campaign to analyze their composition. They attest the persistence, even though it was thought until now that only gold was coined, of a silver coinage of transition, which still borrows from the Byzantine models while developing its own iconographic originality.
Des érudits du XIXe siècle à Adrien Blanchet : la genèse des études de trésors monétaires en France
Authors: Drost Vincent
Published: October 2023

Adrien Blanchet is generally considered as the founding father of coin hoard studies in France. However, Blanchet’s masterpiece, Les trésors de monnaies romaines et les invasions germaniques en Gaule (1900), relies on reports by 19th century local scholars. The latter’s works have been judged quite harshly by modern numismatists. Imperfect as they may be, early hoard studies have the merit of existing at a time when single collectible items were preferred over archaeological groups of objects. Also, they provide thoughtful insights on the way coin hoards were dealt with, physically as well as scientifically, in 19th century France.
Comportamento espacial de espécies arbóreas de interesse comercial, por estratos e pós-colheita seletiva na Amazônia Brasileira
Authors: da Silva Almeida Leal Glória , Da Silva Almeida da Cruz Adriana , Cerqueira Martins Bianca , Assis Leal Fabrício
Published: October 2023

Conhecer o padrão de distribuição espacial das espécies arbóreas constitui uma importante ferramenta para o manejo e a conservação de ecossistemas naturais, pois fornece informações úteis para o entendimento da ecologia e para avaliação da estabilidade das comunidades vegetais. Objetivou-se avaliar a distribuição espacial de espécies arbóreas, por estratos da floresta e após a exploração florestal. Para obtenção dos dados, realizou-se o inventário florestal, onde alocou-se 40 parcelas, nas quais mensurou-se a altura e o diâmetro a altura do peito (DAP) de todos os indivíduos com DAP ≥ 15cm. Os indivíduos foram divididos em três classes de estratos de altura. O padrão de distribuição espacial foi avaliado pelo índice de Morisita, cuja significância foi calculada pelo teste de aderência Qui-quadrado (p<0,05). Para a maioria das espécies, o valor do χ² calculado foi maior que o χ² tabelado, indicando padrão agregado em todos os estratos da floresta. A exceção ocorreu para as espécies Couratari guianensis (estrato inferior) e Cariniana estrellensis (estrato superior), pois ambas apresentaram padrão agregado, quando não estratificadas, e padrão aleatório com a estratificação vertical da floresta. Quanto a exploração florestal, o índice de Morisita indicou que a colheita seletiva não alterou o padrão de distribuição espacial das espécies em estudo. Portanto, estes resultados inferem que o manejo florestal sustentável garante a conservação destas espécies na área de exploração e manejo.

Published: October 2023

The growing interest in integrated agricultural production systems has increased the search for information about the arboreal component, thus, information about the correlations and associations between dendrometric and allometric variables are important. This study investigated the results obtained through simple correlation analysis and its breakdown via path analysis of dendrometric and allometric variables of Eucalyptus benthamii under different integrated systems and monoculture. The following variables were evaluated: diameter at 1.3 m above ground, total height, volume with and without bark, crown radius and biomass components stem wood and bark, branches, leaves and total aboveground biomass. Descriptive statistics showed the great variance of the data with coefficients of variation from 18 to 85.08%. All correlations (Spearman) between allometric and dendrometric variables were positive and 89% were statistically significant (p < 0.05). For the total aboveground biomass as dependent variable, the variables with the greatest direct effects were wood biomass (0.26), volume with bark (0.17) and branch biomass (0.15). With the results of the simple correlation any variable can be used in the modeling of the total aboveground biomass. However, the path analysis makes it clear that some variables have weak associations even with significant correlations of great magnitude.
Focos de calor e desempenho de índices de perigo de incêndios no período de 2017 a 2021 em Jataí – Goiás

Published: October 2023

O bom desempenho de um índice de perigo de incêndios florestais pode ser útil para sua prevenção. Os objetivos deste trabalho foram avaliar a variação no número de focos de calor observados em Jataí – Goiás entre os anos de 2017 e 2021, relacioná-los com os parâmetros meteorológicos e avaliar o desempenho de índices de perigo de incêndios florestais (Angstron, Nesterov, Telitsyn, Fórmula de Monte Alegre e Fórmula de Monte Alegre Alterada). Foi realizada correlação entre os dias com perigo de incêndio e o número de focos e o número de dias com focos de calor. Nos cinco anos, ocorreram 535 focos de calor (em 147 dias), que variaram anualmente de 62 a 157, respectivamente, em 2018 e 2020. O mês de setembro concentrou o maior número de focos de calor (277), seguido por agosto (99). As variáveis meteorológicas variaram anualmente e mensalmente (com marcada sazonalidade) durante a série temporal estudada. O ano mais quente foi 2017 (23,47°C) e 2018 o mais frio (22,88°C), com registro da maior precipitação acumulada (1.485,60 mm). Os meses entre maio e setembro apresentam menores temperatura do ar, umidade relativa do ar, temperatura do ponto de orvalho e precipitação. Apenas a temperatura do ar se correlacionou com os focos de calor (r = 0,67), porém sem significância (p = 0,23). A fórmula de Monte Alegre demonstrou melhor desempenho que os demais índices de perigo de incêndios para Jataí no período analisado.
Ley de acceso a la información como instrumento para la realización de investigaciones forestales en Brasil
Authors: dos Santos Vieira Diego , Leles Romarco de Oliveira Márcio , Oliveira Lafetá Bruno
Published: October 2023

La Ley de Acceso a la Información (LAI) permite el acceso a cualquier información, siempre que no sea confidencial o personal. Los inventarios forestales presentados a los organismos públicos probablemente entran en el ámbito de la LAI, lo que los convierte en una solución viable a la falta de recursos financieros que subsidian la investigación forestal en la Amazonia. El objetivo fue evaluar la LAI como instrumento para realización de investigaciones forestales y, con base en ello, evaluar la estructura diam[étrica y el patrón espacial de copaíba y uchi. El protocolo para solicitar el acceso al inventario forestal se realizó por medio del e-SIC. La estructura diamétrica[ese calculó para una amplitud de 10 cm, mientras que el patrón espacial se obtuvo por la función K de Ripley. Los inventarios forestales están sujetos a la LAI y por tanto, no se consideran confidenciales ni personales. El período de obtención de inventarios fue de 20 a 30 días. El período, ubicación, objeto requerido y el recorte temático son aspectos fundamentales para aprobar la solicitud de acceso a los inventarios forestales. Las especies presentaron una estructura diamétrica tendiente a la normalidad. Esto sugiere un desequilibrio entre las tasas de mortalidad y de reclutamiento causado por la baja producción de semillas o condiciones edafoclimáticas desfavorables. La especie uchi presentó un patrón espacial agregado, mientras que los árboles de copaíba presentaron un patrón variable en función de la distancia. Estos patrones espaciales son resultados de los síndromes de dispersión y heterogeneidad del hábitat.

Maestro Martino: designing a historic escape room with primary school children
Authors: Botturi Luca
Published: October 2023

Educational escape rooms are being used in all school sectors and in many different subjects across the globe. In most documented cases, escape rooms are designed by teachers and played by students. This paper presents the case study of a primary school class that designed and developed an escape room for both adult and young players in connection with a regional event connected to a historical celebration. The project spanned over the whole school year and included a learning phase, the production of support materials (as comics) and eventually the design and development of the escape room, which was finalized by a local association. After its installation in the ancient local prison, the escape room enjoyed the visit of over 600 players, including tourists, families, groups of friends, and school classes, representing a successful example of open school game design project. The paper presents the key phases of the project: requirement analysis, escape room design (including narrative, puzzles, game-flow and props), escape room implementation, and assessment, with a focus on how to manage complex game design with young children.
Mathematics and Sign Language Learning with a Tangible Game: An Inclusive Approach for DHH and Hearing Children
Authors: Casimiro Cátia , Neves José Carlos , Sousa Carla
Published: October 2023

The purpose of this study was to investigate the potential of a tangible game, Inclusive Glossary of Mathematical Terms (GIM), to support the teaching of math and Portuguese sign language (Língua Gestual Portuguesa; LGP) to preschool and first-grade children, with an emphasis on inclusive education, knowledge acquisition, and engagement. GIM is composed of physical cards that are complemented by digital videos that run on an interface designed for this game. The game consists of two sets of cards and respective animations. As an inclusive math glossary, it also includes videos where concepts, characters, and objects are identified through images, words, and sign language. During the development process of GIM, it was possible to involve a multidisciplinary team, of which a Deaf sign language teacher and a sign language interpreter were part to ensure the clarity of the sign language and refine the written sentences accompanying the glossary. In order to validate its contents, a focus group of preschool and primary teachers specialized in the teaching of Deaf and Hard of Hearing (DHH) children was formed. A total of 120 children, aged between three and eight years old (M = 5.61; SD = 0.78), and seven LGP and special education teachers from three Portuguese schools participated in the study. The children used GIM in their classrooms, with the assistance of the participating teachers, who were subsequently interviewed to assess their engagement, interest, and learning outcomes. The interviews were analyzed using content analysis procedures, including descriptive statistics and Pearson correlations. The results indicated that GIM has the potential to effectively support the teaching of mathematics and LGP to preschool and first-grade children, especially in inclusive education contexts. The tangible nature of the game facilitated children's understanding of mathematical concepts and LGP, leading to improved involvement in the teaching-learning process. Moreover, the game promoted awareness of diversity and the principles of inclusive education, making it a valuable tool for promoting social inclusion and understanding. However, the study has reduced sample and context-specific limitations, suggesting a need for further research in this area.
A Video Game to Teach Young Adults the Brain Basics of Addiction
Authors: Reyes Andrés Felipe
Published: October 2023

While we struggle to find effective ways to prevent drug-related harm in young people all around the world, families and communities continue to get hurt. World-renowned experts on addiction believe if people understand its basics, they will make better decisions regarding drug use. Nonetheless, addiction happens in the brain, and the bases of brain function involved in addiction are quite complex. I asked whether young adults could learn with a video game some important basics of synaptic function in the brain related to addiction. My team and I developed ‘You VS Drugs’, a 3D video game beta which, through an adventure that takes place inside a synapse between two cells, explains some of the complex bases of brain function different drugs alter to produce their effects, including addiction. I ran an online questionnaire in which, as 340 young adults aged 18-25 viewed the video game content, answered five multiple-choice and two true-false questions which sought to measure their learning. Then, we ran a simulation with a thousand hypothetical participants who would answer the questionnaire at random. We found that, on average, participants had significantly greater performance on the questionnaire than the simulation group (p <.00001, r = .77). Also, the average of correct responses participants gave over the course of the video game (5.644) corresponds to a group performance of 80.63% in the questionnaire. Results show young adults understand complex bases of neurobiological function related to the effect of psychoactive substances and addiction while playing ‘You VS Drugs’, and they also highlight the potential video games have to teach complex subjects in an engaging way. If we want to reduce the misery drug addiction imposes on families in our societies, we should educate young people in any effective way possible.
The Novelty of Collaboration: High School Students Learning and Enjoyment Perceptions When Playing Cooperative Modern Board Games
Authors: Sousa Micael , Sousa Carla , Luz Filipe
Published: October 2023

Modern board games are changing the way people play analogue face-to-face multiplayer games. One of the novelties of this trend is the growing prevalence of games that offer collaborative gameplay. These cooperative games have been instrumental in shifting the demographic of players, attracting individuals who prefer engaging in constructive interactions rather than destructive confrontations. Likewise, playing cooperative games demand specific players' skills which can be associated with the concept of soft skills. Training these skills through modern cooperative board games, whether by modifying existing games or developing new ones as serious games or using gamification approaches, holds promising potential. To test the perception of students playing cooperative modern board games for the first time, we organized a one-day play session in a school environment, specifically in a classroom with the support of the students’ teachers. Over a period of six hours (three in the morning and three in the afternoon), a total of 25 high school students from the vocational multimedia area, comprising students of all genders, participated in the session. The students engaged in gameplay with a curated selection of four cooperative modern board games. The results indicate that the students enjoyed the game sessions and recognized the significance of collaboration, as well as the associated skills including communication, empathy, organization, focus, and complementary interactions. The experiment reinforces the suggestion that the used modern board games could be introduced during classes as engaging activities fit for learning and training.
Kuxtal: Student Motivation Through Megagames in Higher Education Design Students
Authors: Ludert Edgar , Olivas Castellanos Elsa Catalina , Ramírez-Cavazos Leticia Isabel
Published: October 2023

Megagames are an engaging combination of different game resources. They involve role-play, social connection, simulations, rules, economics, politics, decision making among others that are merged into an immersive narrative, all of which are essential applications of experiential learning. They can last from one day up to one month, they are known to be collaborative and can be played by several players at the same time. In education, collaboration between individuals is an integral competence that has to be nurtured among the academic community. During the game dynamics, multiple experiences, events, and actions are activated that enhance curiosity and emotions among students which, in turn, impact their motivation in the learning process. Wicked problems are undetermined problems that  are resistant to change, possess a social and cultural context, several stakeholders are involved and overall are complex to solve. In this paper we explore 1) the use of megagames as a component to motivate student-learning of Higher Education (HE) students of the fourth semester of a degree in Design at the Tecnologico de Monterrey institution, located in the northwestern region of Mexico in the State of Sonora. We also 2) analyzed if research and action was triggered among students through the megagame, Kuxtal. The megagame, aims to promote student-learning through understanding wicked problems: that all living beings face in regards to water: its scarcity, its pollution and its mismanagement. In this qualitative study, we used Jones (2021) user guide for assessing components of the MUSIC model of motivation to understand empowerment, usefulness, success, interest, and caring. With the incorporation of megagames in the classroom, educators were able to promote student motivation and students engaged in research methodology, all while adopting small world-changing actions in their everyday lives. This paper aims to promote the advantages of using megagames as an educational resource in Higher Education creative fields such as Design, Architecture and Communication.

This study explores applying design science research (DSR) frameworks to facilitate cross-disciplinary collaboration towards game development. It uses a DSR framework proposed by Peffers et al (2014) to integrate the knowledge and experiences of a cross-disciplinary research team and develop a game which gamifies the investment decision-making process of energy communities. The framework employed for this paper constituted five phases around problem identification, definition of solution objectives, artefact design and development, demonstration and evaluation. The iterative process of the framework allowed for gradual but incremental improvement in the outcome and the associated artefacts and sustained researcher collaboration. The resultant interactive in-person game required the participants (or their teams) to navigate through the complexities of the decision-making process in a community while considering factors such as information asymmetry, uncertain return on investments, time constraints, etc. The game was instantiated twice and was able to engage players effectively. Moreover, the post-game evaluation indicated that the players acquired learning about energy communities. The participants developed an understanding of the game only gradually and their engagement in the later rounds of the game. Three distinct investment strategies emerged from the two instantiations (diversification, focus on centralised options, or focus on decentralised options). The participants preferred to maintain a strategy rather than reacting situationally. This gamification experience, albeit applicable to this specific research context, shows that DSR frameworks can be successfully applied to facilitate cross-disciplinary collaboration because they allow for more flexible and iterative knowledge exchange. The post-game evaluation helped identify avenues for further improvements, such as focusing on incremental-iterative development of the output, expanding the flexibility and visibility of the game, involving a more balanced research team, etc. The contribution of this study lies in extending the discourse on cross-disciplinary collaboration by incorporating DSR frameworks and demonstrating the application of game-based learning beyond end-user application.

Digital serious games for adult learning have become a more prominent topic for research in recent years, yet platformer genre games for learning remain underexplored. Despite this, many adults enjoy platformer games for entertainment which presents the question of what about platformer games makes them less prominent in adult education learning games. Platformer games often focus on simple mechanics such as collecting and race to the finish which map well to lower-order learning but require more effort to map to higher-order learning. To address this case, we rapidly designed and developed a 2D platforming game prototype called Biomes Rescue for use in a large general-education undergraduate Geography course. The game follows an Indiana Jones-style character who collects and aligns items to different biomes by evaluating items collected. The problem follows the slime-like creatures: the enemy representing pollution that has impacted Earth’s biomes. Three biomes have been disassembled by the enemies and the player must rescue all four biomes by critically thinking about the characteristics of each. We actively tested and adjusted Biomes Rescue over the last three years and focus this case on the latest implementation, which addresses the alignment of game mechanics to higher-order learning and Knowles principles of Andragogy combined with games-based learning. We hypothesized participants would have an unbalanced view of the dexterity-centered mechanics tied to fun more so than learning. Our mixed-methods exploratory study aims to understand what mechanics connect to fun and to learning from the learner’s perspective using a quiz score - a newly added measure, and Likert scale ratings on Enjoyment with open-ended feedback. Data analysis consisted of thematic analysis and group differences on the quiz scores. This study holds implications for designing platformers for adult learners with an understanding of the differences in game mechanics application for engaging critical thinking.
Game design as reflective pedagogy in entrepreneurship education

Published: October 2023

The relationship between business education and games, primarily simulation games, dates to the 1930s in Europe and the 1950s in the US and continues to grow today. These games are often used to teach action-oriented disciplines, such as marketing, strategy, and entrepreneurship, providing situations in which decision-making under risky circumstances can be practiced. Our research shifts the focus from playing games to designing them for learning. Our game design activity brings the ambiguity and uncertainty from the entrepreneurial environment into the classroom, where risks can be taken, and failure is part of the experience. Students dive into an iterative design process grounded in inquiries and investigations. This requires communication and negotiation skills, aiming to construct dynamic business representations in constant conversation with the situation. Although students' lack of professional experience and game design knowledge poses challenges, the design activity uncovers many learning possibilities and discoveries. Our pedagogical approach attempts to embrace constructionists’ learning characteristics by using a board game to mediate the design process, besides the gameplay. Students' designs should not only reflect their problem-solving experiences, identities, and understandings, but also construct meaning through conceptualizing business interpretations as game elements, mechanics, and rules. Through observations in university classroom settings (Canada, France, and Brazil), we present examples of students' game designs and how they interpreted entrepreneurial challenges through their designs. By employing design thinking to create conceptual representations in a meaningful game, they showed their understanding of entrepreneurship, worldviews, and contextual knowledge grounded in their sociocultural contexts. A board game became a tool that embodied design possibilities based on low-cost resources and was used in classrooms without computers, internet access, or other technical devices. A board game provides an inclusive and immersive learning experience that supports better conceptual understandings of systems, such as entrepreneurial activity. This research contributes not only to understanding the role of board games in business education (in contrast with prevalent digital simulation games) but also motivates the next generation of entrepreneurial educators to experiment with novel teaching methods.
Classroom Introduction of a Video Game on Italian Grammar
Authors: Andreoletti Massimiliano
Published: October 2023

Despite Italian teachers’ strong interest in the use of games, especially the digital ones, there are several critical issues due to their lack of familiarity with games/video games thus making games’ adoption in teaching complex because teachers have only limited time to prepare and play a game-based learning game. Therefore they feel uncertain about using games in class due to their limited knowledge of digital games and find it difficult to identify appropriate assessments, they also find it difficult to integrate video games effectively and efficiently into their classroom, it is also difficult for them to choose appropriate games for teaching. Additionally the school/administration doesn’t assist their effort to support and improve their skills in game-based learning. The learning of the fundamentals of the Italian language and grammar are described and defined by the Italian Ministry of Education within the “National Indications for the ‘Italian Language’ Curriculum”. However, multiple difficulties often make it arduous to learn the basics of the Italian language. The video game “Ross and the Sgrammanebbia” - which can be translated as “Ross and the Un-grammar-Fog” - is a didactic grammar web video game that has a correspondence between the levels and the topics of the textbook as well as giving the teacher a valid help to organise a didactic path studied on the curricular skills. In order to define the useful guidelines for an effective introduction of the game in the classroom, participatory qualitative-quantitative research was prepared on the methods that a small group of teachers put in place to design the training activity with video games. The research focused on: analysis of the educational design skills for the use of games: definition of learning goals, assessment methods and identified teaching strategies; evaluation of the pedagogical activities implemented to facilitate the introduction of games in the classroom; analysis of the roles played by the teacher during all the phases of the training activity - from the design of the training activity to the introduction of the game in the classroom, to evaluation.
Unveiling Radical Mediation: Navigating Body- Mind, Affect, and Technology in Media Literacy
Authors: Regis Fátima
Published: October 2023

Combating disinformation, fake news, and hate speech has become one of the main challenges for media literacy studies. Recent research reveals that affective/emotional factors and confirmation bias prevail in how users interact with media content. This paper draws on the conceptions of the affective turn (Clough, 2010), the embodied mind (Varela 1990), and the concept of radical mediation (Grusin, 2015) to demonstrate how the body and affect act in interaction with the media, producing a kind of intensification of affective interpersonal relationships, generating states of mind that circulate and influence people's reactions to facts and opinions. It highlights how non-conscious aspects affect conscious thinking. It is concluded that strategies based on rhetorical and sociolinguistic structures are insufficient to combat disinformation. It is necessary to carry out inter and transdisciplinary research that adds bodily and affective factors to the ways in which users engage with the media.
Waldorf Education and Anthroposophy – A Complex Relationship
Authors: Goldshmidt Gilad
Published: October 2023

Waldorf education (Steiner e ducation) is one of the most well-established and largest alternative education approaches in the world. This educational approach was created out of the Anthroposophical worldview founded by Rudolf Steiner and relies on the teachings of Anthroposophy. However, the relationship between the educational practice in Waldorf kindergartens and schools and the worldview behind it is complex and multi-faceted, both from the internal point of view of those who work from within Waldorf education and from the critical point of view of external researchers. Indeed, Waldorf education has been criticized and attacked in many ways over the years, particularly for these reasons.
In this article, I shall attempt to throw l ight on this connection and explain it from different aspects. First, I shall briefly present Rudolf Steiner's life path and teachings, i.e. the anthroposophical worldview, and then I shall show how Steiner, the founder of Waldorf education, viewed the connection between Anthroposophy and Waldorf education. Subsequently, I shall explicate why and how this connection has been subject to criticism from various sides. Finally, I shall present two ways that try to elucidate this connection and justify it before its critics.
المصلحة المعتبرة في تجريم الاعتداء على المرافق العامة
Authors: كاظم اسراء , عبود سامر
Published: October 2023

تعد المرافق العامة اكثر المؤسسات أهمية في الوقت الحاضر، لما لها من دور في تقديم الخدمات اليومية للمواطنين لسد احتياجاتهم، ومن ثم تساعد الدولة على التطور والتقدم في شتى المجالات الاجتماعية والاقتصادية وحتى الأمنية منها، كما ولها دور كبير في خلق بيئة يملئها الاستقرار والعيش الكريم.  

وللأهمية الكبيرة للمرافق العامة امتدت يد المشرع الى حمايتها وتنظيمها في كثير من النصوص القانونية ففرد لها الكثير من النصوص سواء في القوانين التنظيمية أو حتى الجزائية، ولأن النصوص الجزائية أكثر النصوص القانونية أهمية لما لها من دور كبير في الحماية، فضلاً عن ارتباطها بحقوق الأفراد وحرياتهم، لذلك صار لزاماً البحث في تلك النصوص واستجلاء المصلحة من تشريعها لأن فلسفة المشرع في النصوص الجزائية هو مصلحتها.                    

 وللوقوف على المصلحة المعتبرة في الجرائم الواقعة على المرافق العامة قسمنا البحث الى مبحثين، خصصنا المبحث الأول لبيان مفهوم المصلحة والمرافق العامة، أما المبحث الثاني وضحنا فيه المصلحة محل الحماية الجنائية للمرافق العامة.
