Published: October 2021

The study aimed at investigating morphofunctional and hematological features of the first-year students’ health condition. The health status for a total of 400 first-year students, who arrived for studying from the northern region (North Kazakhstan) and the southern region (Turkestan, Kyzylorda), was estimated during the study. The morphological (BMI, vital lung capacity, etc.) and hematological (the total number of red blood cells, white blood cells, the concentration of hemoglobin in the blood, etc.) indicators of the health status were investigated. By comparing the condition of physical health in students from both regions, a significant difference in main morphofunctional and hematological indices has been established. The functional indicators of the cardiovascular and respiratory systems were higher in students from the southern region, which reflects a good adaptive reaction to studying at a university, as well as new climatic and geographical conditions. Students from the southern region were reported to have lower red blood cell amounts and diagnosed with mild anemia compared to those from the northern region. Therefore, constant monitoring of the health condition among youth is required to develop effective tactics for the students’ smooth adjusting to living in new climatic conditions.

A comprehensive assessment of the intertidal biodiversity along the Portuguese coast in the early 2000s
Authors: Pereira Joana , Ribeiro Pedro , Santos António , Monteiro Cátia , Seabra Rui , Lima Fernando
Published: October 2021

The unprecedented rates of current biodiversity loss have motivated a renewed interest in environmental and biodiversity monitoring. The need for sustained monitoring strategies has prompted not only the establisment of new long-term monitoring programmes, but also the rescue of data from historical or otherwise archived sources. Amongst the most valuable datasets are those containing information on intertidal systems, as they are particularly well suited for studying the biological effects of climate change. The Portuguese rocky coast is quite interesting for studying the effects of climate change on the distribution of species due to its geographical orientation, latitudinal patterns in temperature, species richness, species' distribution patterns and availability of historical information. This work aims at providing a comprehensive picture of the distribution and abundance of intertidal macro-invertebrates and macro-algae along the Portuguese rocky coast in the early 2000s.

This study provides a description of the rocky shore intertidal biodiversity of the mainland Portuguese coast in the early 2000s. The spatial distribution and semi-quantitative abundance of a total of 238 taxa were assessed at 49 wave-exposed locations. These data provide a comprehensive baseline against which biodiversity changes can be effectively and objectively evaluated.
Derived karyotypes in two elephantfish genera (Hyperopisus and Pollimyrus): lowest chromosome number in the family Mormyridae (Osteoglossiformes)
Authors: Simanovsky Sergey , Medvedev Dmitry , Tefera Fekadu , Golubtsov Alexander
Published: October 2021

The African weakly electric elephantfish family Mormyridae comprises 22 genera and almost 230 species. Up-to-date cytogenetic information was available for 17 species representing 14 genera. Here we report chromosome number and morphology in Hyperopisus bebe (Lacepède, 1803) and Pollimyrus isidori (Valenciennes, 1847) collected from the White Nile system in southwestern Ethiopia. Both taxa displayed the diploid chromosome number 2n = 40, but they differed in fundamental numbers: FN = 66 in H. bebe and FN = 72 in P. isidori; previously the same diploid chromosome number 2n = 40 was reported in an undescribed species of Pollimyrus Taverne, 1971 (FN = 42) from the same region. Our results demonstrate that not only pericentric inversions, but fusions also played a substantial role in the evolution of the mormyrid karyotype structure. If the hypothesis that the karyotype structure with 2n = 50–52 and prevalence of the uni-armed chromosomes close to the ancestral condition for the family Mormyridae is correct, the most derived karyotype structures are found in the Mormyrus Linnaeus, 1758 species with 2n = 50 and the highest number of bi-armed elements in their compliments compared to all other mormyrids and in Pollimyrus isidori with the highest number of bi-armed elements among the mormyrids with 2n = 40.
Âges de la vie et peinture de soi
Authors: Laneyrie-Dagen Nadeije
Published: October 2021

Cet article porte sur les rapports de l’autoportrait et de l’âge. En fonction de quels critères – de quelles sensibilités propres au temps, au lieu, à l’artiste lui-même – un peintre choisit-il ou non de montrer son image à différents âges. La réflexion porte principalement sur les artistes de l’âge moderne. Il s’agit de montrer comment certains d’entre eux ont refusé de se peindre après un certain moment, pour ne laisser d’eux-mêmes qu’une image glorieuse ; tandis que d’autres ont cultivé avant l’heure et parfois exalté l’image d’une grande vieillesse. Léonard de Vinci, Dürer, Rubens, Poussin, Rembrandt, sont au cœur de ces analyses.

Published: October 2021

Il faut soigner l’hôpital, Jean Oury l’a maintes fois répété. Nous pouvons élargir le propos à l’institution médico-sociale, et particulièrement dans notre propos aux établissements d’hébergement pour personnes âgées dépendantes. Le traitement néolibéral, par la gestion des budgets et des humains, assure le glissement vers des structures de plus en plus concentrationnaires où soignants, soignés, patients, résidents sont soumis au cloisonnement, à l’isolement en unité spéciale, aux dérives de systèmes d’enfermement sur lesquels règnent l’arbitraire. Si la question sociétale du genre envahit aujourd’hui les approches, il nous semble primordial d’observer dans quel contexte elle se pose et à quel endroit elle vient se greffer.
Rappeler le cadre

Dans une institution qui se veut éducative ou thérapeutique, c’est l’ensemble du fonctionnement et son organisation qui créent un cadre matériel et symbolique. Quand cela est travaillé on parle de pédagogie institutionnelle, de psychothérapie institutionnelle. Sinon, les éducateurs et les soignants « rappellent le cadre » dans des démarches vaines de rappel non structurant à des règles qui ne font qu’interdire ou régler.
Remp’s Ceiling Paintings in the Palais Attems in Graz
Authors: Požin Karin
Published: October 2021

In the 17th and 18th century reproductive prints were one of the main mediators of artistic solutions and played a key role in the creation of ceiling paintings. This article discusses their use in three monumental frescoes in the Palais Attems in Graz, made by Franz Carl Remp (1674–1718) between 1705 and 1711, for Ignaz Maria Count Attems (1652–1732). All three frescoes testify of Remp’s use of reproductive prints made after works by Italian painters Pie- tro da Cortona (1596–1669) and Annibale Carracci (1560–1609). In some cases, Remp’s scenes are almost identical copies of depictions in reproductive prints, while sometimes they served as a compositional template or source for motifs, which he combined with other visual sources creating a whole new iconographic message.
L’histoire d’un vrai faux traité philosophique (Ḥatatā Zar’a Yā‘eqob et Ḥatatā Walda Ḥeywat). Épisode 1 : Le temps de la découverte. De l’entrée en collection à l’édition scientifique (1852-1904)
Authors: Wion Anaïs
Published: October 2021

Au milieu du xixe siècle, sur les hauts-plateaux d’Éthiopie, un missionnaire catholique, Juste d’Urbin, fait le choix de cesser d’évangéliser pour se consacrer entièrement à l’étude des langues ge‘ez et amharique et de la civilisation orthodoxe éthiopienne. Son mentor est Antoine d’Abbadie alors célèbre pour ses travaux scientifiques sur l’Éthiopie. Juste d’Urbin lui envoie le résultat de ses travaux, en particulier deux copies d’un texte philosophique très rare dont l’auteur serait un penseur éthiopien du xviie siècle. Ce premier épisode d’une série dédiée à l’histoire et aux statuts que connut ce texte, le Ḥatatā Zar’a Yā‘eqob, et son appendice, le Ḥatatā Walda Ḥeywat, montre comment ceux-ci trouvent place dans l’œuvre de Juste d’Urbin, en analysant l’ensemble des manuscrits qu’il envoya à Antoine d’Abbadie et en exploitant la correspondance inédite entre les deux hommes. Linguiste, traducteur, Juste d’Urbin voulut contribuer aux études éthiopiennes. Ses lettres révèlent aussi un penseur inquiet et ambitieux, soucieux de faire œuvre de philosophe. Peut-être les Ḥatatā furent-ils une réponse à cette double ambition ?

Transmettre l’histoire de l’Afrique
Authors: Hirsch Bertrand
Published: October 2021

À travers la lecture critique de quelques ouvrages traitant de l'Afrique et de son histoire, cette note cherche à comprendre ce qui, dans la transmission de l'histoire des sociétés africaines, ne fonctionne pas, ou moins bien que pour d'autres régions et civilisations. Pourquoi tolère-t-on un amateurisme, un « à-peu-près » généralisé ? Les confusions, les erreurs dans l'ordre de la chronologie ou de la géographie, les raccourcis hasardeux se perpétuent ou renaissent sous de nouvelles formes, pour une raison assez simple : ils ne sont pas relevés, comme s'ils n'avaient pas de pertinence. Ce qui signifie qu'il n'existe pas de savoir commun sur l'histoire de l'Afrique, pas plus dans les milieux savants que dans le grand public ou parmi les journalistes.
A historical overview of the Wärğəḥ Muslim community in the Christian highland of Šäwa
Authors: Ayenachew Deresse
Published: October 2021

The Wärğəḥ Muslim community constitutes more than 22,000 people in Ethiopia. They live in diverse parts of the country, but the largest number of Wärğəḥ are found in north Šäwa and near Dəre Dawa. In north Šäwa, the community of Wärğəḥ has established scattered pockets of villages between Däbrä Berhan and Säbäta towns. Linguistically, they speak Oromo and also Amharic. Fragmentary medieval Ethiopian historical sources describe the Wärğəḥ as inhabitants of the lowlands of south-east Šäwa. They were herdsmen, particularly camel keepers. Post-16th century sources record that the Wärğəḥ transformed their way of life to become traders following the great medieval caravan trade routes. Due to their resistance against expansions, they were described as warriors and a ferocious people. For the purpose of this paper, we have gathered oral accounts from 13 local villages of north Šäwa to identify how these people reconstruct their history and to understand how all these villages networked with each other to endure the waves of dynamic religious and population movements of these periods. Funerary stelae were also surveyed to determine whether their styles could be related to the megalithic cultures of south-west Ethiopia.
Déchiffrages. Quelques réflexions sur l’écriture libyco-berbère
Authors: Casajus Dominique
Published: October 2021

Les Touaregs utilisent des alphabets dont les caractères sont appelés tafineq, mot où l’on trouve une racine FNQ que certains auteurs ont rapprochée, à tort ou à raison, du terme dont les Grecs désignaient les Phéniciens. Ces alphabets dérivent d’alphabets beaucoup plus anciens, qu’on a pris l’habitude de qualifier de « libyques » ou « libyco-berbères ». On trouve des inscriptions « libyques » dans tout le Maghreb, depuis la Libye jusqu’au Maroc et même jusqu’aux îles Canaries, parfois associées à des inscriptions puniques ou latines. La découverte à Dougga (Tunisie) de deux bilingues puniques-libyques dont la rédaction remonte au iie siècle avant J.-C. a permis le déchiffrement partiel de l’une des variantes de l’alphabet libyque. Des inscriptions marocaines sont probablement plus anciennes, mais les datations proposées sont sujettes à caution. En même temps qu’il rend compte de deux ouvrages récents, consacrés pour l’un à des inscriptions rupestres contemporaines et pour l’autre à l’évolution des écritures libyco-berbères de l’Antiquité jusqu’à nos jours, le présent article discute quelques-unes de ces hypothèses de datation, et évoque les circonstances de la première découverte des inscriptions de Dougga.
Arts rupestres, écritures et protoécritures en Afrique : l’exemple du libyque
Authors: Quellec Jean-Loïc Le
Published: October 2021

Certaines images rupestres sahariennes pré- ou protohistoriques ont été interprétées comme une protoécriture rupestre susceptible d’avoir évolué vers les écritures libyco-berbères en intégrant un ancien stock de signes régionaux (tatouages, marques de tribus, etc.). L’examen du dossier conduit au rejet de cette hypothèse.
L’île de Bilāq dans le Kitāb Nuzhat al-Muštāq d’al-Idrīsī (XIIe siècle). Généalogie d’une confusion
Authors: Seignobos Robin
Published: October 2021

La description de l’île de Bilāq chez le géographe al-Idrīsī, au xiie siècle, tranche nettement avec les récits de ses prédécesseurs et ne correspond que très partiellement à l’îlot de Philae auquel Bilāq est d’ordinaire identifiée. Alors qu’elle est normalement située légèrement en amont de la première cataracte, Bilāq devient chez Idrīsī une immense île localisée bien en amont de la Vallée, en plein pays nubien, au confluent du Nil et d’un fleuve provenant d’Éthiopie. Les commentateurs modernes s’accordent à reconnaître qu’il y a là un amalgame probable avec la région de l’interfluve Nil-Atbara, sans parvenir pour autant à en comprendre les raisons. Cet article s’efforce précisément d’examiner les sources et les méthodes mises en œuvre par le géographe de Sicile afin d’éclairer la généalogie de cette confusion. Celle-ci repose en dernier lieu sur la difficulté à adapter des informations hétérogènes, dont une partie au moins est issue d’entretiens oraux avec des voyageurs, au cadre ptoléméen dans lequel Idrīsī entend les fondre. L’île de Bilaq se superpose alors au souvenir rémanent de l’île de Méroé, figure majeure de la géographie ptoléméenne du Haut Nil.
« VU » pour vulnérable : la police à l’assaut des problèmes sociaux
Authors: Ouellet Guillaume , Bernheim Emmanuelle , Morin Daphné
Published: October 2021

Le système pénal apparaît de plus en plus comme un moyen de responsabiliser les individus qui ne correspondent pas à l’idéal du citoyen productif, doublé d’un dispositif pour orienter ceux-ci vers des traitements qui leur permettront de participer pleinement à la société. À partir d’une analyse de la littérature sur le sujet et des résultats de deux projets de recherche menés au Québec, cet article propose de mettre en lumière la manière dont les services policiers participent activement au virage thérapeutique de l’État, en ciblant et en intervenant de façon intensive auprès d’individus catégorisés comme étant « vulnérables ».
Location-Based Internationalization and Localization With Mobile Computing
Authors: Sharma Arpit Kumar , Dhaka Arvind , Nandal Amita , Sinha Akshat , Choudhary Deepika
Published: October 2021

The Android system operates on many smartphones in many locales. Websites and web tools have their own requirements in day-to-day life. To reach the maximum users, the app and website should handle all the resources such as text strings, functions, layouts, graphics, and any other static data that the app/website needs. It requires internationalization and localization of the website and app to support multiple languages. The basic idea of this chapter is to present an approach for localizing the Android application according to the location data that the app received from the device, but many users do not allow the “access location” feature so this approach will be a dead end in this case. The authors have proposed some other techniques to achieve this feature of localization and internationalization by implementing the “choose language” service so that the app can itself optimize its content and translate it into the user's native language.
XHAC
Authors: Bagci Das Duygu , Birant Derya
Published: October 2021

Explainable artificial intelligence (XAI) is a concept that has emerged and become popular in recent years. Even interpretation in machine learning models has been drawing attention. Human activity classification (HAC) systems still lack interpretable approaches. In this study, an approach, called eXplainable HAC (XHAC), was proposed in which the data exploration, model structure explanation, and prediction explanation of the ML classifiers for HAR were examined to improve the explainability of the HAR models' components such as sensor types and their locations. For this purpose, various internet of things (IoT) sensors were considered individually, including accelerometer, gyroscope, and magnetometer. The location of these sensors (i.e., ankle, arm, and chest) was also taken into account. The important features were explored. In addition, the effect of the window size on the classification performance was investigated. According to the obtained results, the proposed approach makes the HAC processes more explainable compared to the black-box ML techniques.
Animal Activity Recognition From Sensor Data Using Ensemble Learning
Authors: Birant Derya , Yalniz Kadircan
Published: October 2021

Animal activity recognition is an important task to monitor the behavior of animals to know their health condition and psychological state. To provide a solution for this need, this study is aimed to build an internet of things (IoT) system that predicts the activities of animals based on sensor data obtained from embedded devices attached to animals. This chapter especially considers the problem of prediction of goat activity using three types of sensors: accelerometer, gyroscope, and magnetometer. Five possible goat activities are of interest, including stationary, grazing, walking, trotting, and running. The utility of five ensemble learning methods was investigated, including random forest, extremely randomized trees, bagging trees, gradient boosting, and extreme gradient boosting. The results showed that all these methods achieved good performance (>94%) on the datasets. Therefore, this study can be successfully used by professionals such as farmers, vets, and animal behaviorists where animal tracking may be crucial.
Prototype Implementation of Innovative Braille Translator for the Visually Impaired With Hearing Deficiency
Authors: Santra Soumen , Deyasi Arpan
Published: October 2021

Text-to-Braille conversion as well as speech-to-Braille conversion are not available in combined form so far for the visually impaired, and there is tremendous need of a device that can look after this special class of people. The present chapter deals with a novel model that is designed to help both types of impaired people, be it visual problem or related with hearing. The proposal is itself unique and is also supported by experimental results available within the laboratory condition. This device will help people to read from text with their Braille language and will also help to convert the same form to audio signal. Since text and audio are the two main interfaces for any person to communicate with the external world apart from functionalities of sensory organs, the work has relevance. With the help of DANET, the same data, in text or speech form, can be accessed in more than one digital device simultaneously.
SARS-CoV-2 Is a Robot Bioweapon
Authors: Yan Li-Meng , Cheok Adrian David
Published: October 2021

Two possibilities should be considered for the origin of SARS-CoV-2: natural evolution or laboratory creation. In the authors' earlier report titled “Unusual Features of the SARS-CoV-2 Genome Suggesting Sophisticated Laboratory Modification Rather Than Natural Evolution and Delineation of Its Probable Synthetic Route,” they disproved the possibility of SARS-CoV-2 arising naturally through evolution and instead proved that SARS-CoV-2 must have been a product of laboratory modification. Despite this and similar efforts, the laboratory creation theory continues to be downplayed or even diminished. This is fundamentally because the natural origin theory remains supported by several novel coronaviruses published after the start of the outbreak. Here, however, the authors use in-depth analyses of the available data and literature to prove that these novel animal coronaviruses do not exist in nature.
Do Smart City Solutions Contribute to the Achievement of the Sustainable Development Goals?
Authors: İkizer İhsan
Published: October 2021

Sustainable development and smart city have been two key concepts that are mentioned and referred to in any discussion on our cities. Today, more than half of the people live in cities, and the problems that we face in urban areas ranging from climate change to transportation, from waste management to communicable diseases, threaten the future of our cities and next generations. The Sustainable Development Goals (SDGs) were adopted by the world leaders at the UN Summit in 2015 in order to save our planet, our generation, and next generations. As the problem is global, the solution needs to be global; and as the problem is a result of multiple actors, the solution needs to be provided by the collaboration of multiple stakeholders. Smart city has emerged as a concept that offers several solutions to the urban problems, which also overlap with most of the targets listed in the SDGs. In this chapter, the contribution of smart city technologies to the achievement of the SDGs is analysed through the in-depth case study of Istanbul, a mega city with a population of around 16 million.
Smart Culture and Heritage, the “Rare” Category of SSC Classifications
Authors: Asikis Konstantinos , Nakas Ioannis
Published: October 2021

ISO and ITU propose some classifications regarding the smart sustainable cities services: energy, transport, health, tourism, education, safety, environment, governance, commerce, buildings, community. Culture and heritage is a rare category in these classifications, despite the fact they have to be always been included in an SSC ecosystem. They could play a key role in achieving the 17 SDGs due to some critical reasons: their deep roots in humanity, their wide spread across city life and environment, hence their horizontal connections with all the other SSC categories. There are many options of SSC structures, which have the potential to be dedicated on culture and heritage. QR codes, GIS., VR, apps, IoT, virtual events are some of them, widely implemented by cities. Via these ways, culture and heritage could 1) contribute to the humans' welfare index and 2) interact with the other sectors of the city ecosystem. Their added value to the sustainability process creates the necessity to be a distinctive category in international SSC classifications.
From Smart Homes to Smart Cities
Authors: Emekci Seyda
Published: October 2021

The United Nations has set the Sustainable Development Goals that guide a wide variety of programs to build a better and more sustainable future for all. The goals are not only universal but also connected with each other and indivisible. Since cities are hosting more than half of the world's population and held responsible for three-quarters of global energy consumption and GHG emissions, the Agenda 2030 includes city-related goals. Many countries have taken steps towards reducing greenhouse gases and increasing energy efficiency in cities. To achieve that, smart technology solutions have been developed and adapted to cities. Making cities smart should start from the home level because they have the biggest share in cities' energy consumption and GHG emissions. This chapter reveals the potential contribution of smart homes to smart city concepts in terms of energy efficiency and GHG emissions with the help of the bottom-up approach. In addition to presenting an extensive literature review to the reader, it also discusses how smart technologies contribute to citizen welfare.

Fatigue Characterization and Fractographic Analysis of Aluminium 6063 Alloy
Authors: M. Sreearravind , S. Ramesh Kumar , C. Ahilan
Published: October 2021

Aluminium and its alloy are widely employed in various automobile and aircraft areas because of their unique specific strength and formability. Al alloys that have been employed in aerospace structural components will undergo dynamic loading, which leads to fatigue due to mechanical stress and thermal conditions. Considering studies toward the low cycle fatigue behaviour of Al alloys are significantly narrowed, this chapter sighted to the analysis of fatigue behaviour of Al 6063 alloy at the various total strain amplitude (TSA) of 0.4% and 0.8%, which performed through the low cycle fatigue testing machine at the frequency rate of 0.2 Hz. The test results show that for 0.4% TSA, the number of cycles to failure (N) is 1786, whereas as the TSA increases, N got reduced. For 0.8% TSA, the cycle to failure is 291 and samples undergone cyclic softening during the test. The rate of cyclic plastic strain raised up with the increase in the TSA. Crack propagation was observed along with the quasi-cleavage fracture for 0.4% TSA and cleavage fracture for 0.8% TSA.

Authors: Narayanan R. Ganesh , Ramulu Perumalla Janaki , V. Satheeshkumar , Agrawal Arvind K. , Das Sumitesh , P. Ajay Kumar , Namboodiri V. Vishnu
Published: October 2021

Tailor-made metallic structures are fabricated by welding, adhesive bonding, and mechanical joining methods. Here the aim is not only to fabricate lightweight structures, but also to develop novel methods of joining. Lightweight structures are advantageous in several ways including reduction of fuel consumption and vehicle emissions. Developing novel methods of joining is advantageous due to the possibility of joining of dissimilar materials, improved mechanical performance, and microstructures. In the chapter, initially, tailor-welded blanks (TWB) are introduced, and after that, fabrication of TWBs by laser welding, friction stir welding, and friction stir additive manufacturing are elaborately discussed. Some critical issues in modeling the deformation during fabrication of TWBs is also discussed. A brief account of mechanical behavior of adhesive bonded sheets and mechanical joining are presented in the later part.
The Role of Self-Assembly in Additive Manufacturing of Aerospace Applications
Authors: Vargas-Bernal Rafael
Published: October 2021

Additive manufacturing is a strategy to produce parts with complex geometries whose process is prohibitive in cost or impossible through subtractive or formative techniques. Research groups are optimizing additive manufacturing processes to improve their performance and reduce the cost of aerospace parts. One of the emerging design techniques is self-assembly which seeks to reduce the number of parts to produce best design practices and rules. Self-assembly represents a comprehensive strategy that improves process time, product quality, cost of materials, and printability. The purpose of this chapter is to review the technological contributions that self-assembly has had in the additive manufacturing of aerospace parts. Future perspectives of the role of self-assembly in additive manufacturing are proposed. According to what was found in this research, self-assembly will facilitate the additive manufacturing of parts in various technological sectors where the manufacture of lightweight parts with high added value and restrictive regulations are required.

Closed Captioned
Authors: Hinchman Timothy
Published: October 2021

This chapter investigates the constraints impact on the creativity of millennial preservice teachers when captioning a New Yorker Magazine cartoon. According to research, millennials have a decreased capacity for unique ideas, synthesis, articulation, and open-mindedness, which limits their ability to function in a diverse world. The study examined the topic using the constraint-based model of novelty (C-BMN; creativity problem, constraints, variability, and problem spaces) as a framework, as well as the new rubric, which assessed data on the impact of constraints on creativity among 90 millennial PST. Inferential statistics were used to compare differences in creativity, and the results indicated a statistically significant difference in total caption creativity between the experimental and control groups. The study corroborated previous research, concluding that constraints foster creativity. The findings of this study have implications for stakeholders interested in incorporating constraint-based strategies to increase cognitive diversity.
Youth Bulge in a Pandemic-Stricken World
Authors: Batool Madiha
Published: October 2021

As the year 2020 dawned, the world underwent a paradigmatic shift that impacted all aspects of life. While it is axiomatic that the coronavirus pandemic left an indelible effect on all age groups, the author is especially interested in analysing the impressions that the pandemic can leave on the lives of youth. With history providing anecdotes of contagions having led to political violence and widespread massacres, this chapter will explore how the current pandemic can lead to youth radicalisation in an age of social media and in countries witnessing youth bulge. This study will be carried out at the intersection of international relations, international security, and political psychology and within the parameters of youth bulge, social-psychology, and radicalisation. In doing so, the author will propose a prognostic approach to provent youth radicalisation rather than prevent it in retrospect.

The objective of this study was to explore the acculturation strategies present in the ethnic groups in the internal migration process in Peru, from the self-perception of social well-being and psychological acculturation, as conflict prevention factors. The study methodology was non-experimental and cross-sectional, comprising a non-probabilistic sample of 214 migrants of Quechua ethnic origin residing in Lima and Callao. The results indicated that just over half of the participants perceive themselves as integrated or assimilated to the host society. The results of the research show the prevalence of acculturation strategies linked to social welfare, where internal immigrants of Quechua origin and language seek integration into the environment that enables the performance of roles in the public and private spheres that facilitate adaptation processes and minimization of conflicts.

The topic of tax behavior always stirs attention among scholars, professionals, national and international authorities, organizations, and citizens alike since it is a complex matter. There are four types of tax behavior acknowledged in the literature, namely voluntary tax compliance, enforced tax compliance, tax avoidance, tax evasion. The complexity of tax behavior stems from the fact that there are a manifold of factors influencing it, from economic to psychological ones. The chapter surveys relevant sources on tax behavior in the quest for eliciting the impact of ethnic diversity on tax compliance. At the same time, the difference between countries are also addressed.

Published: October 2021

This study investigates the mediated moderating relationship of self-concept clarity, materialism, and social consumption motivation in the context of Covid-19 pandemic based on the terror management theory. The findings suggest that Malaysian consumers have high self-concept clarity about their materialistic orientation. This materialistic orientation may be of hedonistic-utilitarian nature that is internally directed for self-satisfaction and not exclusively directed externally in material consumption to portray an image to others. Furthermore, this study posits that cultural factors like collectivism and uncertainty avoidance delimits the applicability of terror management theory in Malaysia, suggesting that the development of the theory draw heavily from Western ideology of individualism not directly relevant in the Asian context. Finally, this study offers an understanding of the self-concept clarity from the Asian context, addressing the the appeal by Dunlop (2017) to investigate the construct of self-concept clarity particularly in non-Western context.

Published: October 2021

Football fans are consumers with special relationship with their favourite teams. Consumer-brand relationship is unique and ultimate in football context. However, the absence of these relationships is mainly due to a lack of communication and interaction. This research aims to investigate the impact of brand personality and fan personality on fan- brand relationships. Mixed methods were conducted that employed in-depth personal interviews with football professionals and fans to gain better insights regarding consumer-brand relationships and to develop a conceptual framework and research hypotheses. Then, a quantitative phase has been followed to test these hypotheses. 471 valid questionnaires were collected through a non-probability convenience sampling technique from Egyptian football fans. The findings have shown that brand personality and fan personality have a positive impact on each of interdependence, commitment, partner quality, self-connection, nostalgic attachment, intimacy as consumer-brand relationship dimensions in the football context.

The objective of this paper is to examine a model to identify Social Engineer Attack Phases to improve the security countermeasures by Social-Engineer Involvement. A questionnaire was developed and distributed to a sample of 243 respondents who were actively engaged in 3 Jordanian telecommunication companies. All hypotheses were tested using (PLS-SEM). The results of the study indicate that Social Engineer Attack Phases (Identification the potential target, Target Recognition, Decision approach, and Execution) have a partially mediate and significant impact on improving the security countermeasures by Social-Engineer Involvement. On the other hand, the Social Engineer Attack Phases (Information Aggregations, Analysis and Interpretation, Armament, and Influencing) have a fully mediate and significant impact on improving the security countermeasures by Social-Engineer Involvement. The findings of this study help to provide deep insight to help security professionals prepare better and implement the right and appropriate countermeasures, whether technical or soft measures.
Schema Evolution in Multiversion Data Warehouses

Published: October 2021

Data warehouses (DWs) evolve in both their content and schema due to changes of user requirements, business processes, or external sources to name a few. Although multiple approaches using temporal and/or multiversion DWs have been proposed to handle these changes, an efficient solution for this problem is still lacking. The authors' approach is to separate concerns and use temporal DWs to deal with content changes, and multiversion DWs to deal with schema changes. To address the former, previously, they have proposed a temporal multidimensional (MD) model. In this paper, they propose a multiversion MD model for schema evolution to tackle the latter problem. The two models complement each other and allow managing both content and schema evolution. In this paper, the semantics of schema modification operators (SMOs) to derive various schema versions are given. It is also shown how online analytical processing (OLAP) operations like roll-up work on the model. Finally, the mapping from the multiversion MD model to a relational schema is given along with OLAP operations in standard SQL.

Early and automatic segmentation of lung infections from computed tomography images of COVID-19 patients is crucial for timely quarantine and effective treatment. However, automating the segmentation of lung infection from CT slices is challenging due to a lack of contrast between the normal and infected tissues. A CNN and GAN-based framework are presented to classify and then segment the lung infections automatically from COVID-19 lung CT slices. In this work, the authors propose a novel method named P2P-COVID-SEG to automatically classify COVID-19 and normal CT images and then segment COVID-19 lung infections from CT images using GAN. The proposed model outperformed the existing classification models with an accuracy of 98.10%. The segmentation results outperformed existing methods and achieved infection segmentation with accurate boundaries. The Dice coefficient achieved using GAN segmentation is 81.11%. The segmentation results demonstrate that the proposed model outperforms the existing models and achieves state-of-the-art performance.

An ad hoc structure is self-organizing, self-forming, and system-free, with no nearby associations. One of the significant limits we must focus on in frameworks is leading. As for directions, we can send the packet or communications from the sender to the recipient node. AODV Routing Protocol, a short display that will make the tutorial available on demand. Machine Learning (ML) based IDS must be integrated and perfected to support the detection of vulnerabilities and enable frameworks to make intrusion decisions while ML is about their mobile context. This paper considers the combined effect of stooped difficulties along the way, problems at the medium get-right-of-area to impact layer, or pack disasters triggered by the remote control going off route. The AODV as the Routing MANET protocol is used in this work, and the process is designed and evaluated using Support Vector Machine (SVM) to detect the malicious network nodes.
