Compaction force generated by blasting load requires strong material such as steel to act as a plunger to spread the force evenly. The problem with this method is retaining the plunger's original dimension from intolerable deformation. This paper uses ABAQUS software to study the ability to predict the response of solid cylindrical aluminium bars (6061) subjected to different close-in blast loads. The solid cylindrical aluminium bars treated as a plunger were evaluated numerically using a combination of the finite element method (FEM) and smoothed particle hydrodynamic (SPH) methods. The plunger was simulated using the Johnson-Cook (J.C.) model, and Jones-Wilkins-Lee (JWL) equation parameters modelled the explosive. Field tests were conducted by detonating explosives of two different weights, which are 100g and 250g, in the designated blast area. Both data and observation were compared and analysed regarding deformation behaviour in term of dimension difference and fracture. Based on the graph of the deformation dimension versus the plunger length, the deformation trend shows a very close relation between numerical and experimental data with a percentage error of less than 4%. The fracture mode generated using FEM is comparable to the actual specimen. This fracture mode can be described as similar to the behaviour of the specimen obtained using the Taylor impact test. Thus, it can be concluded that the numerical analysis performed for this study is consistent with the actual results.

Published: January 2024

Nowadays, rigid pavement construction has widely used in road construction industry. Although rigid pavement is widely used in road construction, it tends to fail within time due to many reasons. Fatigue is the important aspect in the rigid pavement design. Due to applications of the heavy loads fatigue occurs in the pavement in the form of micro cracks. Fatigue concepts which is an important parameter in cement concrete pavement and mainly failure occurs due to fatigue failure. As a result, it is crucial to optimize and improving concrete structures to suit diverse engineering requirements. This paper investigates the effect of steel fiber on the improvement of structural behavior such as compressive, tensile and also flexural stiffness performance of rigid pavements. In this respect, the concrete mix design accordance to Design of Normal Concrete Mix (DOE) method was employed in the preparation of the specimens. A series of concrete laboratory tests have been carried out to evaluate the mechanical properties of the concrete sample incorporating 1, 3 and 5% of steel fiber. As a result, the performance (compressive, tensile and flexural) of modified rigid pavements improved remarkably 15-60% with 5% additive of steel fibre at 7 and 18 days curing time. Based on these studies, the addition of steel fiber reinforcement into the rigid pavements has a significant effect on mechanical properties of reinforced concrete mixture.

In the context of a CNC machining application, this study proposes an alternate approach for creating toolpaths designed explicitly for machining rectangular bosses utilizing the STEP AP242 file format as a data source. The suggested methodology ensures data accuracy and integrity maintenance by extracting exact geometric information from digital models using Geometric Data Extraction (GDE) tools. The value of the Cartesian multi-point decimal point in the data structure and variations in the reference number of the Cartesian point every time a user accesses and converts to a STEP (AP203) file are two drawbacks of AP203 when compared to the widely utilized AP203 in prior technique studies. This method makes it possible to create G-code efficiently, which is necessary for managing computer numerical control (CNC) machines, by utilizing the power of STEP AP242 and GDE. The process entails finding and separating the rectangular island milling features in the STEP AP242 files, taking out critical geometric characteristics, and creating toolpaths that are optimal for CNC machining. Through this approach, the final G-code instructions are guaranteed to be precisely calibrated to consider every island feature's distinct quality while preserving overall machining efficiency. Several real-world case studies and valuable applications are investigated to confirm the efficacy of the suggested method. The results show significant increases in productivity, decreased waste material, and improved precision of CNC machining, all of which contribute to a more effective and economical production process.

Thermoelectric Bonded Materials (TEBM) weakened by an Inclined Crack Problems (ICP) subjected to remote stress was presented in this study. The problems are addressed by employing the Modified Complex Variable Function (MCVF) method, which incorporates the Continuity Conditions (CC) for the Resultant Electric Force (REF) and Displacement Electric Function (DEF) to formulate the Hypersingular Integral Equations (HSIEs) associated with these problems. By applying the curved length coordinate method, the unknown functions of Crack Opening Displacement (COD), Electric Current Density (ECD), and Energy Flux Load (EFL) are mapped onto the square root singularity function. The resulting equations are then numerically solved using appropriate quadrature formulas, with the traction along the crack utilized as the right-hand term. The obtained COD, ECD and EFL functions is then used to compute the dimensionless Stress Intensity Factors (SIFs) in order to determine the stability behavior of TEBM weakened by an ICP. The numerical results provided demonstrate the dimensionless SIFs at the crack tips. These results exhibit excellent agreement with previous studies conducted on the subject. Additionally, it is observed that the dimensionless SIFs at the crack tips are influenced by factors such as the ratio of Elastic Constants (ECR), the geometry of the cracks, and the coefficients associated with the Electric Current Density (ECD).
Sound Absorption Characteristics of Integrated Membrane-Fabric Materials
Authors: Nur Izzah Hamdan  , Muhd Hafeez Zainulabidin
Published: January 2024

Noise pollution has emerged as one of the most important environmental issues, particularly in developing countries. The use of sound absorption material has proven to be a successful approach for minimizing and controlling noise levels. Combining a membrane or panel with two or more porous materials is a practical approach for sound absorption. However, it often makes the absorber thicker, taking up more space and increasing production costs. This research proposes a new integrated sound absorber that combines a rubber membrane with a fabric to absorb sound at different frequencies. The new material eliminates bulky porous materials, saving space and production costs. By varying perforation sizes, percentages, and backed air gap distances, the study investigates the sound absorption characteristics of the integrated membrane-fabric material. The research has determined that the integrated membrane-fabric material exhibits exceptional sound absorption performance across a wide frequency range, which is influenced by several factors, including the diameter and ratio of perforations, and the depth of the air cavity. Furthermore, the investigation revealed that the positioning of the fabric also plays a crucial role in determining the material's absorption performance.

Published: January 2024

The smoothing technique has been used broadly in data analysis to obtain sharp signals or patterns by eliminating noise or formless patterns from a data set. Various smoothers with great properties were reported in previous studies, mainly non-linear smoothers such as 4253HT smoother. Hence, the 4253HT was selected to be used in this study, with some modifications done on mean 2 with different types of Hanning. The modifications on mean 2 were done by substituting with Geometric, Quadratic, Harmonic, and Contraharmonic means. Meanwhile, three types of Hanning were used in this study, including Tukey, Shitan, and Husain’s type. Moreover, through a simulation study, this study aims to determine the best combination of smoother between four signals, which were Doppler, HeaviSine, Bumps, and Block signals. A Residual Mean Square Error (RMSE) was used as an evaluator to determine and assess the performance of modified 4253HT smoother when utilizing each smoother and noise level. As a result, Hanning Husain exhibited the best performance among all. Moreover, Hanning Tukey performed better on signal Block at lower noise levels (10% and 25%), while Hanning Shitan showed the worst performance. Besides, modified 4253HT using contra harmonic mean smoother recorded the most satisfying outcome in smoothing compared to other smoothers. Therefore, the 4253HT smoother will demonstrate the best performance with the combination of S5 smoother and Hanning Husain. Thus, it is suggested to utilize this smoother in further analysis, mainly in forecasting to provide accurate values and pattern for prediction.

Published: January 2024

Aim: The blood collection for laboratory tests has been frequently performed due to evidence-based medicine. We aimed to conduct a survey on phlebotomy among phlebotomists and patients and to reduce unnecessary blood loss by using small-volume blood collection tubes.

Material and Method: A survey among phlebotomists and patients was conducted to gather their opinions. Phlebotomists received training on the importance of the preanalytical process. The blood volume required for laboratory tests was reduced by 33.3%-50.0% in children and adults, and 63.0%-84.0% in newborns. Following this intervention, we investigated its effects on the blood transfusion ratio in the neonatal and adult intensive care unit (NICU and ICU) and the amount of laboratory medical waste generated.

Results: A majority of phlebotomists (91.8%) reported difficulties in drawing blood from newborns, pediatric, oncology, hematology, and geriatric patients. Additionally, 68.9% of phlebotomists and 57.1% of patients expressed an opinion for reduced blood volume. Despite an increase in the number of laboratory tests (28.4%) and samples (15.7%), we observed a 17.8% reduction in the amount of laboratory medical waste. Although the number of patients in NICU increased statistically significant, the increase in transfusion rates was not significant. Although the number of patients in ICU increased, transfusion rates decreased, but neither was found to be statistically significant.

Conclusion: Post-graduation, phlebotomists should be educated regularly about the preanalytical process. Based on the opinions of both phlebotomists and patients, using small-volume tubes in patients with difficult blood collection may increase their satisfaction. Generally, laboratory medical waste may be reduced.

Producto de tal búsqueda es esta obra que compila información científica actualizada sobre cada una de las plantas reportadas logrando obtener información sobre cada una de ellas acompañada con fotografías de las mismas. Se lograron confirmar como tóxicas un alto número de plantas, también hubo otras sobre las que no se encontró suficiente información como para confirmar su carácter de planta tóxica, siendo principalmente de efecto medicinal y otras sobre las que no hubo ningún tipo de información. Adicionalmente, se pudo demostrar que el reconocimiento de las plantas verdaderamente tóxicas para los bovinos y demás especies animales, se hace necesario para instaurar las medidas terapéuticas y preventivas necesarias, ya que no todas las plantas que se cree que son tóxicas, realmente lo son.
The Integration of Bohemian and Hungarian Aristocrats into the Spanish Habsburg System via Diplomatic Encounters, Cultural Exchange, and News Management (1608–1655)
Authors: Monostori Tibor
Published: January 2024

The composite state of the Spanish Habsburgs had a fading military, financial and diplomatic predominance in Central Europe in the first half of the seventeenth century. The Bohemian and Hungarian aristocracy was, to varying extents, integrated into the Spanish Habsburg system. This article presents three forms of integration and diplomatic relationship. First, it examines diplomatic and political encounters in the main governmental bodies and diets advising the emperor in decision-making, or more specifically, in the Imperial Privy Council in Vienna and during the diets of the kingdom of Hungary. Spanish Habsburg politicians and diplomats acted in many powerful ways to establish connections with Bohemian and Hungarian aristocrats so that they follow and adjust to their political agenda. Bohemian families (Slavata, Martiniz) had close relations and alliances with Spanish councilors in Vienna (who acted as ambassadors of the Spanish king), and several Hungarian aristocrats had interactions with them during the diets in order to secure the long-term interests of the dynasty in the Kingdom of Hungary. Second, the exchange, purchase, and influence of cultural goods and objects (e.g., books and gifts) and the ways in which these cultural goods were put to use, as well as the migration of people, show that the relationship went well beyond power politics and formal diplomatic relations. Personal and cultural influence and even early signs of acculturation can be clearly detected in several Bohemian and Hungarian families (e.g., the Forgách, Pázmány, and Zrínyi families), who ordered and read hundreds of books from Spanish Habsburg authors (including several books from Spanish Habsburg diplomats) and cities and exchanged diplomatic gifts with their Spanish counterparts. People, including influential figures (soldiers and nobles), also moved among Habsburg political centers, prompted by diplomatic or family relations between Spanish Habsburg politicians and Bohemian or Hungarian families. Third, information gathered in Vienna radiated to all Spanish Habsburg states in different layers of granularity, density, and confidentiality. Top Spanish diplomats could access and transmit classified documents and the texts of international contracts obtained from Central European aristocrats and events. They also sent thousands of reports to their superiors about general news in Bohemia and Hungary. At the same time, lower-ranking nobles often struggled to keep up with and understand international events and trends and failed to get information about the key results of wars and imperial diets, since they lacked access to the network and the seniority to exert adequate influence.
“Kejetia Preaching”: An Analysis of Contemporary Phenomena of Street Preaching in Kumasi, Ghana
Authors: Boaheng Isaac , Amoako Clement , Boahen Samuel
Published: January 2024

Street preaching/evangelism is one of the activities undertaken by Christians to broadcast or spread the gospel. It is one of the forms of making disciples of all nations and winning souls for Christ in accordance with the Great Commission of making disciples if all nations (Matt. 28:18-20). In Ghana and some other parts of Africa, street preaching is a common phenomenon. Arguably, street preachers have a larger audience than “pulpit preaching” at the Sunday service. While Sunday service preaching is mostly confined to the chapel and focuses on members of a particular church, street preaching targets and reaches people of varied denominational and religious backgrounds. Though a common practice, street preaching comes with a number of theological, ethical and pastoral issues which need scholarly analysis. The purpose of this paper is to critically assess street preaching from theological, ethical and pastoral perspectives and to recommend ways in which potential pitfalls may be addressed. The paper employed qualitative and historical-descriptive research designs to describe the current state of the exercise and its impact on the soul-winning ministry and Christianity in general. In addition to the data collected from the field through interviews and participant observation, the paper used secondary sources such as books, journal articles and dissertations. After a careful analysis of the subject matter the paper established that even though street preaching is a legitimate and effective way of spreading the gospel, it may contribute negatively to the qualitative growth of the church due to the lack of proper theological/ministerial training of most of these preachers and the resulting unbiblical and unethical practices that sometimes characterize this enterprise. To avert the situation, the paper made recommendations for the nation (Ghana), church and preachers to enhance the qualitative growth of the Christian community through effective and biblically-sound preaching.

APEC y cómo las tensiones geopolíticas podrían afectar la marcha del foro
Authors: Aquino Rodríguez Carlos
Published: January 2024

La guerra comercial y tecnológica de EE. UU. con China, y la invasión rusa a Ucrania, están incrementando las tensiones geopolíticas que podrían afectar el foro APEC, donde esas tres economías están entre los miembros más importantes. En particular China y EE. UU. parecen encaminados a desarrollar cadenas de suministro paralelas, mientras EE. UU. refuerza sus alianzas económicas y políticas en Asia. Esto impactaría en el objetivo del APEC de lograr una Área de Libre Comercio en el Asia Pacifico, el FTAAP. Las demás economías miembros deben aprender a navegar entre estas tensiones entre la rivalidad de las grandes potencias, que parece ser un signo distintivo de las relaciones económicas internacionales en el futuro.
‘Jane Eyre in the West Indies’
Authors: Dawson Clive
Published: January 2024

The development of I Walked with a Zombie, from conception to production, is covered in this chapter. RKO purchased the rights to a newspaper article to form the basis of Lewton’s second film, and commissioned a treatment from the article’s author, Inez Wallace. They also engaged Universal screenwriter Curt Siodmak to write the script. However, Lewton rejected both of these works and instead employed first time screenwriter Ardel Wray to write the production script, using a template loosely based on Jane Eye and Rebecca. He also employed specialist black performers and choreographers to ensure the voodoo element of the film was treated with respect. In doing so, he introduced what Teresa de Lauretis described as ‘a proto-feminist and proto-decolonial perspective … long before feminist and decolonial studies became part of the academic, intellectual and political discourse.’
EFFECT OF DOSE AND TYPES OF THE WATER REDUCING ADMIXTURES AND SUPERPLASTICIZERS ON CONCRETE STRENGTH AND DURABILITY BEHAVIOUR: A REVIEW
Authors: Wang Xiao-Hui , Fang Zhi-Chao , Zheng Li
Published: January 2024

As one of the concrete admixtures, water reducing admixtures and superplasticizers are usually used to reduce the mixing water volume and improve the performance of the harden concrete while maintaining better workability of the fresh concrete. However, the concrete strength and durability properties are affected differently by different types and dosages of the water reducing admixtures and superplasticizers. Based on the published literatures, this paper comprehensively reviews and analyzes this problem. Different types of the concretes, including ordinary Portland cement concrete, ordinary Portland cement concrete containing pozzolan, fly ash and ground granulated blast furnace slag, calcium sulfoaluminate cement concrete, ferrite aluminate cement concrete, recycled aggregates concrete, lightweight aggregate concrete, self-compacting concrete and ultra-high performance concrete, are considered to discuss the influence of types and dosages of the water reducing admixtures and superplasticizers on their strengths. Water absorption, frost resistance and permeability resistance of the concrete are mainly reviewed to discuss this influence on the durability properties of the concrete. Then, some suggestions on the application of the water reducing admixtures and superplasticizers in reinforced concrete structures and projects are proposed.

Abstract

Arctic ecosystems face increasing risks from vector-borne diseases due to climate-driven shifts in disease patterns and vector distribution. However, species identification challenges impact vector-borne disease surveillance, necessitates accurate identification. Aedes species are predominant among Arctic mosquitoes and pose health risks, with some species potentially carrying Jamestown Canyon and Snowshoe hare viruses. However, identifying Aedes species is challenging, especially under Arctic conditions and with complex adult traits. This study assessed the suitability of DNA barcoding (COI and ITS2 regions) and morphological characteristics for the identification of Arctic black-legged Aedes. It also aimed to evaluate the reliability of publicly available sequences. Our analysis focused on Aedes impiger, Aedes nigripes, and two species from the Punctor subgroup – Aedes hexodontus and Aedes punctor. In our study, the COI barcoding region distinguished Ae. impiger and Ae. nigripes but not within the species of the Punctor subgroup. In addition, the ITS2 barcoding region did not differentiate the species. When we evaluated GenBank and BOLD sequences, we found issues of under-representation and misidentifications, particularly within the Punctor subgroup. Based on these results, we recommend addressing identification difficulties, particularly within the Punctor subgroup, and advocate for more comprehensive morphological and molecular identification strategies. Integrating morphology and DNA barcoding holds promise for robust disease surveillance in Arctic regions, yet challenges persist, especially in complex species groups like the Punctor subgroup. Tackling these issues is pivotal to ensuring accurate vector status determination and reliable disease risk assessments in a rapidly changing Arctic ecosystem.

Dynamics in a delayed rumor propagation model with logistic growth and saturation incidence
Authors: Yin Rongrong , Muhammadhaji Ahmadjan
Published: January 2024

This paper studies a delayed rumor propagation model with logistic growth and saturation incidence. The next generation matrix method, some inequality techniques, the Lyapunov-LaSalle invariance principle, and the Lyapunov method are used in this paper. Our results indicate that if the basic regeneration number (which is analogous to the basic reproduction number in disease transmission models) is less than 1, the rumor-free equilibrium point (which is analogous to the disease-free equilibrium point in disease transmission models) is globally stable. If the basic regeneration number is greater than 1, then the rumor is permanent, and some sufficient conditions are obtained for local and global asymptotic stability of the rumor prevailing equilibrium point (which is analogous to the endemic equilibrium point in disease transmission models). Finally, three examples with numerical simulations are presented to illustrate the obtained theoretical results.
Digital currency and privacy
Authors: Kang Kee-Youn
Published: January 2024

We develop a monetary model in which a private company issues digital currency and uses payment data to estimate consumers' preferences. Sellers purchase preference information to produce goods that better match consumers' preferences. A monopoly arises in the digital currency industry, and digital currency is not issued if the inflation rate is sufficiently high. Due to reinforcing interactions between the value of preference information and trade volume, multiple equilibria (with and without digital currency) can exist, depending on market structures for monetary exchanges. When left to market forces alone, socially efficient uses of payment data may not occur.
Data and incentives
Authors: Liang Annie , Madsen Erik
Published: January 2024

“Big data” gives markets access to previously unmeasured characteristics of individual agents. Policymakers must decide whether and how to regulate the use of this data. We study how new data affects incentives for agents to exert effort in settings such as the labor market, where an agent's quality is initially unknown but is forecast from an observable outcome. We show that measurement of a new covariate has a systematic effect on the average effort exerted by agents, with the direction of the effect determined by whether the covariate is informative about long‐run quality versus a shock to short‐run outcomes. For a class of covariates satisfying a statistical property that we call
strong homoskedasticity, this effect is uniform across agents. More generally, new measurements can impact agents unequally, and we show that these distributional effects have a first‐order impact on social welfare.
De la ludification béhaviorale à la ludification humaniste : le « tiers symbolisant » comme médiation dans l’acte communicationnel
Authors: Bonenfant Maude
Published: January 2024

En tant que mode spécifique d’organisation du sens, la ludification s’inscrit dans des processus communicationnels. Or, dans ce contexte d’échange entre un émetteur et un récepteur intervient un troisième terme, le tiers symbolisant, qui inscrit la communication dans une relation triadique. Concept développé par Louis Quéré (1982), le tiers symbolisant offre un modèle explicatif de la complexité de la communication qui s’applique parfaitement en contexte d’échange où la ludification est utilisée pour communiquer. Dans ce chapitre, il s’agira d’évaluer ce que peut nous apprendre le concept de tiers symbolisant sur la manière dont la ludification est productrice de sens (émetteur) et message à interpréter (récepteur) et ce que cette forme langagière nous dit de notre conception de l’humain, des relations intersubjectives et du vivre ensemble selon qu’elle a des visées béhaviorales ou humanistes.
Du game design au play design : éthos et médiation ludique
Authors: Genvo Sébastien
Published: January 2024

Dans un premier temps, à partir d’une synthèse de mes travaux antérieurs (Genvo, 2013), je montre comment la notion d’éthos ludique permet de penser et d’analyser ce qui va permettre à un individu de reconnaitre que « ceci est un jeu » (Bateson, 1972, p. 214) et de devenir joueur, mais aussi les écarts sémiotiques qui peuvent se produire lors de l’actualisation de la structure de jeu. Il s’agit de montrer que ce concept, dès lors qu’il est mis en lien avec la notion de contexte pragmatique et de jouabilité, permet d’aller au-delà de l’expérience immédiate pour comprendre la façon dont un objet réussit (ou échoue) à faire sens ludique au sein d’un milieu donné. J’illustre la mise en application de ce cadre théorique par l’étude de deux initiatives de recherche-création menant au développement de jeux expressifs. Le premier, Keys of a gamespace (Expressive Game Lab), a été réalisé en 2011 et le second, Lie in my heart (2019, Expressive Gamestudio), était en cours de développement au moment de la rédaction de l’article. Ces études nous permettent de montrer conjointement comment une interrogation centrée sur l’éthos ludique amène à considérer les enjeux éthiques du processus créatif de game design et engage une réflexion orientée vers le play design (Genvo, 2008).
L’appareil paratextuel vidéoludique comme lieu d’une double médiation : Survival, survivance et intericonicité
Authors: Baychelier Guillaume
Published: January 2024

Affiches, box art ou encore vidéos constituent un ensemble d’images publicitaires qui accompagnent la parution de la plupart des jeux vidéo. Ce texte s’interroge sur le statut de ces images et sur leur capacité à illustrer, c’est-à-dire à mettre en lumière le contenu de ces jeux — qu’il s’agisse de leur contenu narratif ou ludique. À travers un corpus convoquant l’idée d’horreur (via une iconographie monstrueuse et sanglante), il est montré comment s’opposent plusieurs dynamiques de transposition de l’imaginaire convoqué par ces jeux. Ce texte montre ensuite comment, par l’expression de survivances iconographiques, peut se mettre en place une double médiation ouvrant ces images à un au-delà de la sphère du média jeu vidéo.
Quand la médiation suscite la controverse
Authors: Perret Michael , Moret Pierre-Yves
Published: January 2024

Cet article revient sur la controverse autour du journaliste de jeux vidéo Dean Takahashi de VentureBeat, apparue à la suite de la publication d’une vidéo présentant sa prise en main fastidieuse du jeu Cuphead (2017, StudioMDHR Entertainment). Dans ce qui s’apparente à une véritable cérémonie de bashing de la part d’internautes sur l’individu et sa performance, c’est la qualité requise chez un journaliste pour aborder le monde du jeu vidéo qui est dénoncée, et toute la profession des journalistes de jeux vidéo qui se trouve interrogée. Pour comprendre comment la tentative de médiation journalistique se trouve en partie rejetée, notre approche se réfère à l’analyse énonciative de discours et à la sociologie des problèmes publics. Nous présentons d’abord la triple humiliation qu’a subie Takahashi, pour analyser ensuite comment ces opérations participent d’une cérémonie de dégradation publique où Takahashi et sa catégorie d’appartenance professionnelle vont être déconsidérés notablement, prenant en compte le contexte de méfiance récurrente des gamers envers la presse vidéoludique. L’analyse de la controverse éclaire plus généralement le pouvoir symbolique en jeu dans les critiques, à savoir une manière d’imposer aux autres une définition de la situation et d’articuler qui a le droit de parler de jeu vidéo. Quatre ans après le début de la controverse, nous observons que la cérémonie de dégradation qui visait la personne de Takahashi l’a profondément et durablement discrédité aux yeux d’une partie du public. L’évocation de son nom reste aujourd’hui encore synonyme à la fois d’incompétence et d’illégitimité.
Enseignants : le défi de l’attractivité
Authors: Boissinot Alain , Lessard Claude
Published: January 2024

Recruter en nombre suffisant des enseignants, éviter la démission de ceux qui sont déjà en poste : autant de défis auxquels sont confrontés tous les pays. Les multiples situations analysées dans ce dossier font certes apparaître des différences liées aux contextes sociaux et historiques, mais aussi des constantes qui permettent d’identifier des facteurs décisifs. La reconnaissance du métier, les conditions de travail et d’affectation, la qualité de la formation sont partout évoquées. La comparaison des politiques mises en œuvre pour améliorer le recrutement renvoie à trois enjeux importants : le type d’engagement proposé aux enseignants, l’efficacité des dispositifs de formation, la capacité à dynamiser et à valoriser les évolutions de carrière. Mais par-delà la difficulté à attirer vers le métier d’enseignant, ce qui est en cause est peut-être aussi la capacité des sociétés contemporaines à rendre attractive la mission d’enseignement elle-même.

À La Réunion, le choix est influencé par des considérations statutaires et de mobilité géographique plus centrales qu’en France métropolitaine. À Mayotte, un modèle spécifique génère une attractivité fortement liée aux conditions d’exercice et aux représentations du métier. Celles-ci sont également au cœur des enjeux à Madagascar, face à des besoins et à des difficultés extrêmement importants. À Maurice, la cohabitation installée entre système formel d’enseignement et cours parallèles constitue un trait dominant.
The Transformation of the New Media Communication Paradigm in the Metaverse Era and Blockchain Based on the Topological Characteristics of Information Communication
Authors: Zhang Jinping
Published: January 2024

Keeping pace with the times, this paper analyzes and interprets the concept, characteristics of Metaverse, and its influence on new media communication. Based on this, under the topological characteristics of information communication, this paper discusses the transformation of new media communication paradigm in the metaverse era and models the prediction of new media information dissemination in metaverse. In this paper, the multi-agent modeling method is used to analyze and compare the evolution results of each agent attribute under different parameter values. At the same time, based on the ideal social media network, the improved integrated immune control strategy is applied to the dynamic model of epidemic (SEIR) with latent period, and the spreading and evolution process of rumors before and after immunization is simulated. This research has both theoretical value and practical application value, which can provide a useful reference for the follow-up research of new media communication.
Avaliando problemáticas ambientais vinculadas ao Setor Sucroenergético a partir da Mesorregião Triângulo Mineiro/Alto Paranaíba (MG)

Este estudo examinou as principais questões ambientais relacionadas ao setor sucroenergético na Mesorregião Triângulo Mineiro/Alto Paranaíba (MG), responsável por 70% da produção canavieira de Minas Gerais e que experimentou um aumento de 929,7% na área cultivada em pouco mais de duas décadas. O foco da análise foi o uso intensivo de recursos hídricos, a geração de grandes quantidades de resíduos e a disposição inadequada destes. Os procedimentos metodológicos incluíram ampla coleta e análise de dados, realização de trabalhos de campo e consulta de referências interdisciplinares. Como principais achados, estimou-se serem necessários 47,55 bilhões de litros de água para processamento industrial das 57,99 milhões de toneladas de cana-de-açúcar colhidas na mesorregião – montante superior a todo o volume hídrico consumido pela população (724 mil habitantes) residente nos municípios em que estas centrais sucroenergéticas estão instaladas. Em Pirajuba, a central sucroenergética consumiu 9,5 vezes mais água que a população municipal. Descobriu-se também que cinco dos dezessete municípios que mais cultivam cana-de-açúcar irrigada no centro-sul do país estão na mesorregião. E ainda que o processamento sucroenergético promove elevada (co)geração e descarte de vinhaça, subproduto com alto potencial poluente e concebido em uma razão de 10 a 13 vezes para cada litro de etanol. Trabalhos de campo revelaram que o acúmulo inadequado desse rejeito está diretamente relacionado à proliferação de pragas, como a mosca-dos-estábulos.

A partir da década de 1990, os países latino-americanos vêm recebendo inúmeros investimentos em tecnologias da informação, processo desencadeado pelo atual estágio do capitalismo financeiro. No Brasil, o uso e expansão dos cabeamentos de fibra ótica estão ligados ao período de inserção do país no contexto da globalização informacional. Os ativos estruturais e financeiros controlados pelos Fundos Soberanos de Riqueza e Fundos Privados, tais como o GIC, de Singapura, e o BTG Pactual, respectivamente, são agentes detentores da capacidade de produzir e organizar o território. Os investimentos financeiros nas redes técnicas de telecomunicação imprimem relações de poder que integram, articulam e drenam esse território em diferentes escalas de atuação. Este processo conduz ao debate da lógica de financeirização do território e dos diferentes agentes hegemônicos que estão a constituir as novas dinâmicas de produção das infraestruturas. Pensar a manutenção das desigualdades socioespaciais associada aos investimentos nas redes de infraestrutura de fibra ótica, e quais as implicações territoriais destes investimentos na condição do uso destes instrumentos de comunicação, traz à tona como os diferentes objetos geográficos subscritos no território acarretam na especialização seletiva de certas áreas. Diante disso, este artigo busca contribuir para o entendimento das desigualdades socioespaciais promovidas pelas novas instalações de infraestrutura de telecomunicação, uma vez que se relacionam com as lógicas de interesse de agentes do capital financeiro internacional.
Ação Político-Discursiva e Ideológica na Criação da Zona de Processamento de Exportação (ZPE) de Cáceres, Mato Grosso

O artigo tem como objetivo analisar a ação político-discursiva e ideológica que envolve a criação da Zona de Processamento de Exportação (ZPE) no município de Cáceres, Mato Grosso. Para a consecução do objetivo, foram adotados os seguintes procedimentos: a) Levantamento da literatura sobre o tema para construir um arcabouço teórico conceitual e exploratório; b) Análise documental; c) Trabalho de campo, por meio do qual foi realizada a aproximação com a realidade do fenômeno pesquisado. Foram feitos, além da observação, os registros fotográficos da área de estudo, entrevistas com atores chaves e coleta de extrato de jornais impressos referentes ao período compreendido entre 1988 e 2018, no Arquivo Público Municipal de Cáceres - Mato Grosso. Evidenciou-se que há dissidências político-discursivas e ideológicas frente às diferentes articulações políticas do Estado e de seus principais agentes locais ao longo do processo da implementação da ZPE de Cáceres. Nesse jogo político-discursivo e ideológico ficou claro o uso político da mídia, sobretudo de jornais impressos. Verificou-se que segmentos da elite política regional e local cacerense, apoiando-se sobre certos cenários, empregaram amplas estratégias discursivas. Dessa forma, atuaram alinhando o discurso aos interesses ideológicos desenvolvimentistas, entendendo a ZPE como o único instrumento de política econômica industrial eficaz para promover o desenvolvimento local/regional. A despeito de tal avaliação da elite política e econômica regional, o fato concreto é o de que a implantação da ZPE não se efetivou e ainda se encontra cercada por muitas incertezas.
Aspectos regionais da difusão de covid-19 na rede urbana da Região Geográfica Imediata de Açailândia, Maranhão, Brasil

Published: January 2024

O presente trabalho tem por objetivo compreender a dinâmica de difusão da COVID-19 na rede urbana da Região Geográfica Imediata de Açailândia (RGIA), Maranhão, Brasil. O período de análise compreende o primeiro ano da pandemia, a ser contado a partir do primeiro caso registrado no Maranhão (de 20 de março de 2020 a 20 de março de 2021). Trata-se de uma análise espacial mais empírica, ancorada na sistematização de dados quantitativos secundários e públicos, seguida de exame qualitativo. A análise considera a distribuição de especialidades médicas e equipamentos médico-hospitalares na região geográfica como elemento impulsionador de circulações em busca de atendimento pelo paciente com COVID-19 na rede urbana, entre os centros. São utilizadas três principais bases de dados para a pesquisa: Instituto Brasileiro de Geografia e Estatística (IBGE), Secretaria de Estado da Saúde do Maranhão e Departamento de Informática do Sistema Único de Saúde (DATASUS). Os dados sugerem que a rarefeita e concentrada oferta de serviços de saúde entre os municípios que compõem a região impulsiona fluxos de transeuntes em busca de atendimento e que, em certa medida, reproduzem os padrões de hierarquia da rede urbana-regional, promovendo ampliação da área de contágio, imprecisões quanto à origem de contágio e concentração de óbitos no principal centro regional.
O mercado municipal e o crescimento da cidade de Taubaté, SP: uma análise do período de 1800 a 1950

Os mercados municipais surgiram com o propósito de reorganizar o comércio de produtos alimentícios, marcando significativamente importantes mudanças no espaço da cidade e na vida da população. Neste sentido, este artigo objetivou discutir as transformações ocorridas na cidade de Taubaté, localizada na Região Metropolitana do Vale do Paraíba e Litoral Norte (RMVPL), SP, e a sua relação com o mercado municipal local, bem como realizar uma reflexão sobre a importância deste lugar no processo de construção da cidade, por meio da análise do contexto histórico do crescimento da cidade. Para o desenvolvimento desta pesquisa, adotou-se um recorte temporal, entre os anos de 1800 e 1950, em uma perspectiva geo-histórica, a fim de refletir sobre a relação deste lugar com o crescimento observado. Para tanto, foi realizada uma pesquisa de abordagem qualitativa e caráter exploratório, analisando a implantação, permanência e transformações arquitetônicas, bem como a organização espacial, que perpassam o mercado nas diversas fases do desenvolvimento do município. Os mercados municipais sempre se apresentaram como intermediadores entre o campo e a cidade, e entre cidades, por serem caracterizados como centros de comércio resultantes de cruzamentos de rotas comerciais, que auxiliaram na construção coesa da identidade cultural das cidades. O mercado de Taubaté acompanhou o processo de crescimento do município, em alguns momentos conectado ao processo; em outros, se distanciando da dinâmica da cidade. Entretanto, foi uma referência regional, que contribuiu para o crescimento da cidade, não apenas porque o comércio que lá ocorria impulsionava a sua expansão, mas também por ser rota de acesso à região do Vale do Paraíba.
