The chemical diversity of low-mass protostellar sources has so far been recognized, and environmental effects are invoked as its origin. In this context, observations of isolated protostellar sources without the influence of nearby objects are of particular importance. Here, we report the chemical and physical structures of the low-mass Class 0 protostellar source IRAS 16544−1604 in the Bok globule CB 68, based on 1.3 mm Atacama Large Millimeter/submillimeter Array observations at a spatial resolution of ∼70 au that were conducted as part of the large program FAUST. Three interstellar saturated complex organic molecules (iCOMs), CH3OH, HCOOCH3, and CH3OCH3, are detected toward the protostar. The rotation temperature and the emitting region size for CH3OH are derived to be 131 ± 11 K and ∼10 au, respectively. The detection of iCOMs in close proximity to the protostar indicates that CB 68 harbors a hot corino. The kinematic structure of the C18O, CH3OH, and OCS lines is explained by an infalling–rotating envelope model, and the protostellar mass and the radius of the centrifugal barrier are estimated to be 0.08–0.30 M
⊙ and <30 au, respectively. The small radius of the centrifugal barrier seems to be related to the small emitting region of iCOMs. In addition, we detect emission lines of c-C3H2 and CCH associated with the protostar, revealing a warm carbon-chain chemistry on a 1000 au scale. We therefore find that the chemical structure of CB 68 is described by a hybrid chemistry. The molecular abundances are discussed in comparison with those in other hot corino sources and reported chemical models.

The Lyα emission line is one of the main observables of galaxies at high redshift, but its output depends strongly on the neutral gas distribution and kinematics around the star-forming regions where UV photons are produced. We present observations of Lyα and 21 cm H i emission at comparable scales with the goal to qualitatively investigate how the neutral interstellar medium (ISM) properties impact Lyα transfer in galaxies. We have observed 21 cm H i at the highest possible angular resolution (≈3″ beam) with the Very Large Array in two local galaxies from the Lyman Alpha Reference Sample. We compare these data with Hubble Space Telescope Lyα imaging and spectroscopy, and Multi Unit Spectroscopic Explorer and Potsdam MultiAperture Spectrophotometer ionized gas observations. In LARS08, high-intensity Lyα emission is cospatial with high column density H i where the dust content is the lowest. The Lyα line is strongly redshifted, consistent with a velocity redistribution that allows Lyα escape from a high column density neutral medium with a low dust content. In eLARS01, high-intensity Lyα emission is located in regions of low column density H i, below the H i data sensitivity limit ( < 2 × 1020 cm−2). The perturbed ISM distribution with low column density gas in front of the Lyα emission region plays an important role in the escape. In both galaxies, the faint Lyα emission (∼1×10−16 erg s−1cm−2 arcsec−2) traces intermediate Hα emission regions where H i is found, regardless of the dust content. Dust seems to modulate, but not prevent, the formation of a faint Lyα halo. This study suggests the existence of scaling relations between dust, Hα, H i, and Lyα emission in galaxies.

We examine the redshift evolution of density environments around 2163 radio galaxies with the stellar masses of ∼109–1012
M
⊙ between redshifts of z = 0.3–1.4, based on the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) and Faint Images of the Radio Sky at Twenty cm. We use the k-nearest neighbor method to measure the local galaxy number density around our radio galaxy sample. We find that the overdensities of the radio galaxies are weakly but significantly anticorrelated with redshift. This is consistent with the known result that the relative abundance of less-massive radio galaxies increases with redshift, because less-massive radio galaxies reside in relatively low-density regions. Massive radio galaxies with stellar masses of M

M
⊙ are found in high density environments compared with the control sample galaxies with radio nondetection and matched stellar mass. Less-massive radio galaxies with M

M

M
⊙ (M
* < 1011

⊙). We also find that the local densities around the radio galaxies are anticorrelated with the radio luminosities and black hole mass accretion rates at a fixed stellar mass. These findings suggest that massive radio galaxies have matured through galaxy mergers in the past, and have supermassive black holes whose mass accretion almost ceased at z > 1.4, while less-massive radio galaxies undergo active accretion just at this epoch, as they have avoided such merger events.
The Fundamental Plane Relation for Gamma-Ray Pulsars Implied by 4FGL

We explore the validity of the recently reported fundamental plane (FP) relation of γ-ray pulsars using 190 pulsars included in the latest 4FGL-DR3 catalog. This sample number is more than twice as large as that of the original study. The FP relation incorporates four parameters, i.e., the spin-down power,

cut. The derivation of ϵ
cut is the most intriguing one because ϵ
cut depends on the proper interpretation of the available phase-averaged spectra. We construct synthetic phase-averaged spectra, guided by the few existing phase-resolved ones, to find that the best-fit cutoff energy, ϵ
c1, corresponding to a purely exponential cutoff (plus a power-law) spectral form, is the parameter that optimally probes the maximum cutoff energy of the emission that originates from the core of the dissipative region, i.e., the equatorial current sheet. Computing this parameter for the 190 4FGL pulsars, we find that the resulting FP relation, i.e., the γ-ray luminosity in terms of the other observables, reads as

We present spatially resolved morphological properties of [C II] 158 μm, [O III] 88 μm, dust, and rest-frame ultraviolet (UV) continuum emission for A1689-zD1, a strongly lensed, sub-L* galaxy at z = 7.13, by utilizing deep Atacama Large Millimeter/submillimeter Array (ALMA) and Hubble Space Telescope (HST) observations. While the [O III] line and UV continuum are compact, the [C II] line is extended up to a radius of r ∼ 12 kpc. Using multi-band rest-frame far-infrared continuum data ranging from 52 to 400 μm, we find an average dust temperature and emissivity index of

, respectively, across the galaxy. We find slight differences in the dust continuum profiles at different wavelengths, which may indicate that the dust temperature decreases with distance. We map the star formation rate (SFR) via IR and UV luminosities and determine a total SFR of 37 ± 1M
⊙yr−1 with an obscured fraction of 87%. While the [O III] line is a good tracer of the SFR, the [C II] line shows deviation from the local L
[C II]-SFR relations in the outskirts of the galaxy. Finally, we observe a clear difference in the line profile between [C II] and [O III], with significant residuals (∼5σ) in the [O III] line spectrum after subtracting a single Gaussian model. This suggests a possible origin of the extended [C II] structure from the cooling of hot ionized outflows. The extended [C II] and high-velocity [O III] emission may both contribute in part to the high L
[O III]/L
[C II] ratios recently reported in z > 6 galaxies.
X-Ray Observations of the Isolated Black Hole Candidate OGLE-2011-BLG-0462 and Other Collapsed Objects Discovered through Gravitational Microlensing
Authors: Mereghetti S. , Sidoli L. , Ponti G. , Treves A.
Published: July 2022

Isolated black holes and neutron stars can be revealed through the observation of long-duration gravitational microlensing events. A few candidates have been found in surveys of stars in the direction of the Galactic bulge. Recently, thanks to the addition of astrometric information at milliarcsecond level, it has been possible to reduce the uncertainties in the masses and distances for some of these “dark” gravitational lenses and select the most promising candidates. These isolated compact objects might emit X-rays powered by accretion from the interstellar medium. Using data of the Chandra, XMM-Newton, and INTEGRAL satellites, we searched for X-ray emission in the isolated black hole candidate OGLE-2011-BLG-0462, and in several other putative collapsed objects found with gravitational microlensing. OGLE-2011-BLG-0462 has been recently interpreted as a 7.1 M
⊙ black hole at a distance of 1.6 kpc, although a different group obtained a mass range (1.6–4.4 M
⊙) that cannot exclude a massive neutron star. We have derived upper limits on the flux from OGLE-2011-BLG-0462 of 9 × 10−15 erg cm−2 s−1 in the 0.5–7 keV range and ∼2 × 10−12 erg cm−2 s−1 in the 17–60 keV range. The implied X-ray luminosity is consistent with the small radiative efficiency expected for a black hole and disfavors a neutron star interpretation. Limits down to a factor of about five lower are obtained for the soft X-ray flux of other candidates, but their interpretation is affected by larger uncertainties in the masses, distances, and spatial velocities.
Spatial and temporal distribution dataset of benthic macroalgae during the 2015-2016 tropical monsoonal cycle in Malaysia
Authors: Zainee Nur Farah Ain , Rozaimi Mohammad
Published: July 2022

The effects of small-scale disturbances, such as monsoon, are understudied in tropical regions. The storms associated with monsoon events not only modify the local macroalgal community structure, but also reveal the continuation of short-term recolonisation. Thus, this study aims to determine the variation in species, assemblage and cover of macroalgae during the monsoonal cycle from 2015 to 2016. This paper presents data on the spatial and temporal distribution of benthic macroalgae along the coastline of Johor, Malaysia. The information is presented as raw and partially-processed data, which summarises the cover and frequency of macroalgae at the respective study sites. This paper describes an important set of data that can be used further for in-situ experiments on the effects of environmental disturbances towards pioneer and climax species in tropical areas.

This study provides a description of the east coast shore of Peninsular Malaysia, specifically in Johor coast in 2015-2016. The spatial and temporal distribution and abundance of a total of 41 taxa were assessed at four monsoon-exposed locations. These data provide a comprehensive baseline against disturbance and recolonisation of macroalgal community can be effectively and objectively evaluated.
On the taxonomy and zoogeography of the Caucasian genus Pseudotyphlopasilia (Coleoptera: Staphylinidae: Aleocharinae). IV. Two new species and additional records from Northwest Georgia
Authors: Assing Volker
Published: July 2022

Two field trips to Northwest Georgia conducted in 2021 yielded 29 specimens of the Caucasian genus Pseudotyphlopasilia Pace, 1983, most of them collected by soil-washing. The material belongs to five species, two of them described and three of them unnamed. Two of the unnamed species are described and illustrated: P. confusa spec. nov. (Racha: environs of Lailashi) and P. egrisica spec. nov. (Zemo Svaneti: Egrisi Range). One species remains unnamed for want of males. Additional records are provided for two previously described species, including Pseudotyphlopasilia coeca (Eppelsheim, 1878) (type species of the genus) of which only few and mostly old specimens were previously available. New illustrations are provided for P. coeca and P. acris Assing, 2021. The genus currently contains a total of twelve named species, all of them anophthalmous and micropterous, with eleven of them distributed in Georgia and one in the Russian West Caucasus. The distributions of five species are mapped.

 
3. Capitalism without capitalists. Bankers, capitalists & entrepreneurs in Schumpeter’s theory
Authors: Velardo Tristan
Published: July 2022

Schumpeter théorise le capitalisme grâce à un modèle dynamique qui dépasse le modèle statique par l’introduction d’une nouvelle fonction, l’entrepreneur. Ce dernier est le porteur de l’innovation, mais il a besoin d’un fonds de pouvoir d’achat pour réaliser son innovation. Tous trois absents du modèle statique, banquiers, capitalistes et entrepreneurs sont impliqués dans le processus capitaliste. Ainsi, les capitalistes avec le capital et les banquiers avec le crédit remplissent la fonction économique de prêter des moyens de paiements. Cependant, Schumpeter souligne le rôle crucial du banquier dans l’émergence des innovations aux dépens de l’autre agent central du capitalisme, le capitaliste lui-même. En effet, le rôle et la fonction du capitaliste sont minimisés au profit du banquier, à tel point que ce dernier peut remplacer le premier. Schumpeter semble développer le paradoxe d’une théorie du capitalisme sans capitaliste. La relation entre l’entrepreneur et le banquier semble suffire à stimuler l’évolution économique. Le but de cet article est de questionner le triptyque entrepreneur-capitaliste-banquier à travers leurs relations et fonctions respectives dans le modèle schumpétérien. La distinction entre ces différents acteurs et le paradoxe apparent d’un capitalisme sans capitaliste permet de mettre en évidence la définition schumpétérienne du capitalisme, qui place la monnaie en son centre. Ainsi, l’évolution capitaliste est poussée par un ensemble de moyens dont le cœur réside dans le phénomène de la monnaie empruntée et de la création de crédit. Classification JEL : B15, B25, B31, B52

À travers l’écran
Authors: Rimbaud Alexis
Published: July 2022

Les problématiques liées à l’usage des écrans ne peuvent être traitées en dehors de tout contexte social, historique, politique, voire moral et religieux. En effet, s’il paraît évident, pour certain praticiens, qu’une utilisation excessive de ces appareils ne peut être abordée que sur l’angle curatif ou sanitaire de l’addiction, il convient de s’interroger sans jugement trop hâtif sur la valeur de ces écrans selon une approche plus psychopathologique en questionnant leurs diverses fonctions. Ces usages peuvent en effet révéler une articulation singulière propre à maintenir le sujet dans un état homéostatique particulièrement utile, faisant parfois office de suppléance passagère là où la carence est manifeste.
Les émotions des enseignants auprès d’élèves à besoins éducatifs particuliers : quels inducteurs positifs et négatifs ?
Authors: Petiot Oriane
Published: July 2022

Cet article rend compte d’une recherche qui visait à analyser les inducteurs émotionnels issus de 167 incidents critiques racontés par 50 enseignants auprès d’élèves à besoins éducatifs particuliers. La catégorisation inductive des récits d’expérience recueillis a mis au jour quatre catégories d’inducteurs émotionnels positifs. La principale faisait référence aux succès rencontrés par les enseignants dans l’intervention face aux élèves. Les inducteurs émotionnels négatifs ont également été répartis en quatre catégories. Les deux principales renvoyaient aux manifestations d’agressivité de la part des élèves et aux difficultés à s’adapter au handicap et/ou aux difficultés des élèves. Les résultats sont discutés au regard des spécificités émotionnelles de l’enseignement auprès d’élèves à besoins éducatifs particuliers.

Le système de satisfaction : un outil pour penser la transition écologique
Authors: Haëntjens Jean

Le modèle de la société de consommation est à fois condamné et formidablement cohérent, ce qui explique qu’il perdure. Il ne pourra être dépassé que par une approche méthodique du « système de satisfaction » qui le fait fonctionner et notamment par la transformation de récompenses matérielles en récompenses non financières et immatérielles. En s’inspirant de l’exemple de certaines politiques locales, cet article explicite cette notion et montre son possible apport aux politiques de transition.
Logement et énergie : lutter contre la précarité énergétique et participer à la transition écologique
Authors: Denise Hélène , Domergue Manuel
Published: July 2022

La lutte contre la précarité énergétique est au carrefour des préoccupations sociales et environnementales car ce sont les ménages les plus précaires qui sont les plus touchés par le froid à domicile et les factures de chauffage exorbitantes. Malgré une montée en puissance des politiques de rénovation énergétique depuis quinze ans, la lutte contre les « passoires thermiques » se heurte à un manque de volonté politique : stratégies purement incitatives, manque récurrent d’accompagnement social et professionnel, aides publiques favorisant les effets d’aubaine et les simples gestes de rénovation au lieu de déclencher des rénovations performantes, insuffisance des financements publics, obligations de rénover trop faibles et trop tardives. En l’absence de politiques ambitieuses de soutien des ménages, en particulier les plus modestes, le plan de rénovation peine à convaincre les ménages et à vaincre leurs réticences face à des travaux coûteux, complexes et incertains, au détriment des bénéfices individuels et collectifs de long terme d’un tel chantier.

Published: July 2022

Diagnosis assistant is an effective way to reduce the workloads of professional doctors. The rich professional knowledge plays a crucial role in diagnosis. Therefore, it is important to introduce the relevant medical knowledge into diagnosis assistant. In this paper, diagnosis assistant is treated as a classification task, and a Graph-based Structural Knowledge-aware Network (GSKN) model is proposed to fuse Electronic Medical Records (EMRs) and medical knowledge graph. Considering that different information in EMRs affects the diagnosis results differently, the information in EMRs is categorized into general information, key information and numerical information, and is introduced to GSKN by adding an enhancement layer to the Bidirectional Encoder Representation from Transformers (BERT) model. The entities in EMRs are recognized, and Graph Convolutional Neural Networks (GCN) is employed to learn deep-level graph structure information and dynamic representation of these entities in the subgraphs. An interactive attention mechanism is utilized to fuse the enhanced textual representation and the deep representation of these subgraphs. Experimental results on Chinese Obstetric Electronic Medical Records (COEMRs) and open dataset C-EMRs demonstrate the effectiveness of our model.

Published: July 2022

In the era of the fourth industrial revolution, technology is advancing at a pace much faster than what individuals, societies and nations can cope with. Internet of Things (IoT) is one such technology that is sweeping the economic, business and service landscapes with its disruption mechanisms that influence areas such as smart homes, hospitals, cities, as well as transportation and energy utilization with many exciting and novel applications. Additionally, the job market is evolving at a rate that makes it difficult for universities to sustain a stable programme structure, especially in engineering and information and communication technology disciplines as well as specializations and domains associated with technology. While several universities worldwide have established IoT degree programs at bachelor and master levels, institutions in developing countries are still contemplating the idea of pioneering such venture due to a number of reasons related to technology vacillation as well as market and social acceptance.  Princess Sumaya University for Technology has therefore designed a bachelor degree programme on IoT Engineering in order to bridge the gap in the Jordanian ICT market and to meet demands for specialized engineers in this rapidly evolving area. The university adapted an optimization design process of the program including a cycle of consultation with stakeholders, followed by a formal procedure of rectification and accreditation. The proposed program was successfully a launched at the beginning of the academic year 2021/2022 with an intake cohort of 50 students.
The Importance of Learning Resources for University Students During Emergency Remote Learning

Published: July 2022

Although several studies have evaluated online learning tools and resources, few have investigated how useful they are to students. This topic became even more relevant with “emergency remote learning” due to coronavirus disease 2019 (COVID-19). The present study was conducted at a state educational institution in Mexico that offers five university degrees. The objective was to differentiate the importance of online learning resources by degree and by employment status of the students. This quantitative, relational, cross-sectional study included 969 participants. Jamovi, SPSS, and RStudio were used to calculate descriptive statistics and to perform the Scheirer-Ray-Hare and Friedman tests. The results showed that the most important learning resources are lesson recordings, teacher explanations, instructional materials, and online demonstrations, whereas the least important are exams, videos, homework, and projects. These findings were consistent across the five degrees among students who are employed and those who are not. The results suggest that educational resources should be used according to their importance for student learning.

Published: July 2022

This research aimed to synthesize a review of the literature and theory to develop a flipped classroom (FC) learning model to enhance 1st-year bachelor degree Thai student teacher academic achievement (AA) and problem-solving skills (PSS). The sample consisted of 90 student teachers who enrolled in the Digital Media and Learning Innovation (DMLI) course in the Elementary Education Program in the Education and Liberal Arts Faculty at Hatyai University in southern Thailand’s Songkhla province. The study used the FC model in an experimental group (S2) (n=30), while simultaneously comparing it to the control (S1) group using traditional classroom methods (n=31) and another group (S3) using problem-based learning (PBL) (n=29). The FC’s model development was reviewed by nine academic experts. The quasi-experiment took place over four weeks in March and April 2021. All instruments were evaluated by an additional five academic experts whose input evaluation was analyzed using MANOVA statistics with IBM’s® SPSS® for Windows Version 21 program. The results showed that Flipped PARSER group (S2) had AA results significantly higher than both the traditional and PBL groups. Also, S2’s results concerning their PSS were also significantly higher than S1 and S3 as well, while their student teacher satisfaction was also at the highest level. These results showed that the proposed Flipped PARSER Model excels at promoting the development of undergraduate students' motivation, academic achievement, and PSS.
Towards Data-Driven Network Intrusion Detection Systems: Features Dimensionality Reduction and Machine Learning

Published: July 2022

Cyberattacks have increased in tandem with the exponential expansion of computer networks and network applications throughout the world. In this study, we evaluate and compare four features selection methods, seven classical machine learning algorithms, and the deep learning algorithm on one million random instances of CSE-CIC-IDS2018 big data set for network intrusions. The dataset was preprocessed and cleaned and all learning algorithms were trained on the original values of features. The feature selection methods highlighted the importance of features related to forwarding direction (FWD) and two flow measures (FLOW) in predicting the binary traffic type; benign or attack. Furthermore, the results revealed that whether models are trained on all features or the top 30 features selected by any of the four features selection techniques used in this experiment, there is no significant difference in model performance. Moreover, we may be able to train ML models on only four features and have them perform similarly to models trained on all data,which may result in preferable models in terms of complexity, explainability, and scale for deployment. Furthermore, by choosing four unanimity features instead of all traffic features, training time may be reduced from 10% to 50% of the training time on all features.
A Teaching Practice Design Based on a Computational Thinking Approach for Prospective Math Teachers Using Ed-tech Apps
Authors: Aminah Neneng , Sukestiyarno  , Wardono  , Adi Nur Cahyono
Published: July 2022

The pandemic situation forces us to use technology in learning. Likewise, prospective teachers who do field practice must prepare themselves to learn to use technology. So to overcome this, research was conducted to determine the validity, practicality, and responses of prospective teachers to the Computational Thinking (CT) based teaching practice model for mathematics teachers. This study uses Research and Development (R&D) with the ADDIE model, questionnaire validation, practicality questionnaire and teacher candidate response questionnaire used in the study. The results showed that the design of teaching practice based on the CT approach was very feasible to use, marked by the results of validation, practicality and positive responses from prospective teachers to the practice model used, as well as an increase in creativity of teaching practice. We recommend a CT-based teaching practice model using Ed-Tech on a hybrid learning system. This research is still limited to the mathematics department and for future researchers to carry out this practice in other majors in the university environment.

This study aims to explore and explain the application of blended learning-based projects in electronics engineering education courses. The research method used is a project-based product design and development carried out by blended learning. We conduct our project activities in higher education special students from Electronic Engineering Education that take part in the learning of this project. Students who participate are only limited to small groups to avoid the impact of the Covid-19 pandemic, in 1 small group consisting of 3-5 people and there is 1 group leader who manages the work, while other members are supportive and help complete joint projects. The results of this study show the ability of students to work by implementing project-based learning in producing products, namely Exhaust Fan products based on Electrostatic Precipitator (ESP) as a form of a mini prototype that can be used for small household scale industries. The ability of students to work on product manufacturing by applying the principles of project-based learning in the category already has the ability to, skilled and thoroughly working on the project that was planned until it succeeded in becoming a product prototype which was carried out in project-based blended learning.

Published: July 2022

Semantic Segmentation is the process of assigning a label to every pixel in the image that share same semantic properties and stays a challenging task in computer vision. In recent years, and due to the large availability of training data the performance of semantic segmentation has been greatly improved by using deep learning techniques. A large number of novel methods have been proposed. However, in some crucial fields we can't assure sufficient data to learn a deep model and achieves high accuracy. This paper aims to provide a brief survey of research efforts on deep-learning-based semantic segmentation methods on limited labeled data and focus our survey on weakly-supervised methods. This survey is expected to familiarize readers with the progress and challenges of weakly supervised semantic segmentation research in the deep learning era and present several valuable growing research points in this field.
Traduire « design graphique »
Authors: Philizot Vivien
Published: July 2022

À certains égards, « design graphique » est une notion incompréhensible, recouvrant un ensemble diffus de pratiques, de situations, et d’objets hétérogènes, qui semblent dissuader toute tentative d’en circonscrire les contours sans cesse changeants. Pour saisir au mieux la forme problématique que découpe cette expression à la surface du monde, cet article se propose de suivre au plus près ses multiples traductions. Depuis quels paradigmes et sous quels autres noms, ce que nous nous entendons pour appeler « design graphique » a-t-il été construit, envisagé, théorisé, dans l’histoire récente ? À l’heure où l’on cherche partout sans les trouver les modèles scientifiques de la recherche en design et en design graphique, il est bien utile de remarquer que les objets qui entrent communément dans ces catégories sont appréhendés depuis des années par des champs du savoir voisins. En abordant trois traductions de « design graphique », cet article vise d’une part à donner un peu de netteté à cet ensemble de choses aux contours si diffus, d’autre part à déterminer avec un peu plus de précision les perspectives scientifiques par lesquelles une recherche en design graphique est aujourd’hui envisageable.
Writing to Learn in Science Using the 3D + U(DL) Sensemaking Model
Authors: Drew Sally V. , Thomas Jeff D.
Published: July 2022

This chapter presents a research-based model for integrating writing to learn approaches in science class. The strategies described in this chapter depict an in-depth integration of writing to support content learning and to develop students' knowledge and skill in writing science-specific genres such as argument-based explanation. This offers educators a solution to align science and literacy standards and emphasize discipline-specific writing approaches to bolster learning, and ensures that writing is accessible to all students, including students with exceptionalities. The 3D +U(DL) sensemaking model for writing in science seamlessly integrates four major components that support students' writing and learning: NGSS 3D learning, disciplinary literacy (DL), Universal Design for Learning (UDL), and sensemaking through the 5E learning cycle. The model can be implemented in any science or STEM/STEAM classroom from Grades 3 to 12; however, the example provided in the chapter is from a middle school science classroom.

The Game Pentade
Authors: Raposo Lazaro , Guerra Helia , Morais Carla , Coelho Antonio
Published: July 2022

The use of digital games as support tools for education has proven to be effective. To explore their potential, it is crucial to design them carefully. This chapter considers the design of games for education, where players cultivate their knowledge and practice their skills by multiplying numerous hindrances during gaming. Educational elements are integrated into the gameplay, which players acquire while playing. The game's effectiveness depends on the players' ability to form a cheerful and encouraging environment to continue playing while increasing their interest in gameplay and improving academic performance. Following a design-first development approach, an innovative proposal for this design is presented, adding a new dimension to the game's tetrad: learning dynamics. Benefiting from years of professional practice, this game pentad design framework fulfills the learning and user experience requirements while overcoming the design limitations of more conventional approaches not based on an educational purpose.

Authors: Farbiarz Alexandre , Farbiarz Jackeline L. , Xavier Guilherme , Dias Cynthia M. , Bastos Lucas L. A. , Gonçalves Eloisa F. F. S.
Published: July 2022

This chapter presents the Commercium & Cognitionis project, which aligns technology and playfulness, implementing DICTs and gamification as pedagogical tools that value didactic content and engagement, combining competition and collaboration in the search for knowledge to solve the proposed challenges. The proposal is aligned with the insertion of urban youth into a highly imagetic and technological contemporary culture. Adopting active pedagogical methods that exploit skills and abilities in the game allows the combination of systemic and procedural evaluation in the discipline and the evaluation of knowledge construction. To reach the play goal, it was necessary for the student-player to pursue the didactic objectives, as the evaluation of the experience indicates that dedication to the game positively influenced the academic dedication, also stimulating access and meaningful learning on the programmatic contents and guaranteeing autonomy and independence in the educational process.

Understanding the Challenges of Game-Based Training
Authors: Sanchez Diana R. , Lee Clifton A.
Published: July 2022

Substantial resources have been put towards game-based learning and the use of games in multidisciplinary research and practice. Despite this growing popularity, a definitive link has yet to be established between games and learning outcomes such as improved motor skills or recall of information. The problems researchers face are a series of challenges that prevent researchers from conducting research on game-based learning in a consistent and standardized way. Through reviewing and aggregating the literature, the authors describe five challenges currently facing the area of game-based learning and offer recommendations as to what future research could do to resolve these challenges moving forward. The primary purpose of this chapter is to provide a steppingstone in the game-based learning literature to help move the field away from conflicting research findings and toward a clearer understanding of game-based learning as an educational solution across disciplines.

Background and aims:

Although blood transfusion is generally believed to save human lives, blood can be a vehicle for the transmission of some infectious and parasitic diseases including malaria. So, this study aims to determine the prevalence of blood transfusion malaria among blood donors in the Central Blood Bank in Kassala State, according to age and blood groups.

Materials and methods:

A cross-sectional study was carried out in the central blood bank in Kassala State among blood donors; this study involved one hundred blood samples, collected from donors aged from 18 to 41 years. 

Results:

The results showed that 1 (1%) of the donors was infected with the malaria parasite. The results also showed that the species of the malaria parasite was Plasmodium falciparum; the other Plasmodium species were not found. The results revealed that most donors were blood group O, while AB was the least common blood group; the blood group that harbored the malaria parasite was blood group O, and the other blood groups tested negative. The results also showed the highest number of blood donors was found in the age group of 24-29, and the positive donor was found in the same age group. 

Conclusions:

Both the blood films and immune chromatography test showed one positive result for the donor and the percentage of blood transfusion malaria was 1%.

Authors: Meyer Kristin S. , Roberts Jessica , Sasser Croley Kimberly
Published: July 2022

Background An 81-year-old woman with type 2 diabetes, residing in a long-term care facility, has experienced a fall after medication changes, and a few days of irregular eating. Assessment This patient may be experiencing one or more common potential adverse
events related to her diabetes medications. There is a need to create individualized treatment goals in this case. Outcome After a revision of treatment goals for hypertension and diabetes, and adjustments to the medication regimen, there have been no subsequent falls and
this patient reports that she feels better. Conclusion As the person with diabetes ages, quality of life should be considered when setting treatment goals. Older people can be more at risk for adverse effects of medications to treat diabetes, so a clinician should be vigilant
in the identification, management, and prevention of such adverse events. Inter-professional communication is key to the safe and effective treatment of diabetes.
