Authors: Shinde Sweety , Mohan Vineetha , Kamat Rima
Published: December 2024

A 65-year-old male presented with progressive loss of vision since six months. Radioimaging suggested
optic glioma. On biopsy, malignant melanoma and metastases of hepatocellular carcinoma (HCC) were
considered. Positivity for pan-cytokeratin and HepPar markers conrmed the latter. Orbital metastases of HCC are associated
with high mortality. Awareness of this rare entity can aid in intraoperative diagnosis.

Published: December 2024

We intend to contribute our findings about the prevalence of cardiac
arrhythmias in the Indian population. Cardiovascular diseases (CVD)
are one of the world's main causes of mortality and disability,
accounting for 31.8% of all deaths. Moreover, according to the Global
Burden of Disease (GBD) study, there were 422 million instances of
[1] CVD in 2015, with South Asia accounting for the largest contributor.
CVDs such as heart failure (HF) and cardiac arrhythmias (CA) are the
[2] major non-communicable diseases among the Indian population.
Arrhythmia refers to an abnormal heartbeat. Patients with arrhythmia
show a wide range of presentations, from palpitations to sudden
cardiac arrest. Arrhythmia is generally associated with an elevated risk
of cardiovascular diseases including stroke, ischemic heart disease,
HF, and sudden cardiac death. Early diagnosis and treatment of
arrhythmia are crucial to prevent risks of CVDs. Studies highlighting
the prevalence of cardiac arrhythmia in the Indian population are
lacking. The current study aimed to report the prevalence of
arrhythmias in the Indian population. The study was conducted in the
adult population from 20 cities of India, including Ahmedabad,
Bengaluru, Bhubaneshwar, Chandigarh, Chennai, Dubai, Ernakulum,
Ghaziabad, Hubli, Guwahati, Hyderabad, Indore, Jaipur, Kolkata,
Lucknow, Madurai, Mumbai, Nagpur, Pune, and Vijayawada.
Electrocardiograph (ECG) screening was done for the detection of
abnormalities.

Authors: ADEDINA Femi , Joy OSO, Oluwagbemi
Published: December 2024

Society consists of people with different cultures, religions, backgrounds, educational and financial statuses, lifestyles, beliefs, and values. Popular culture refers to the common and general beliefs that we share and have in common and consists of fashion, politics, art, leisure, trends, entertainment (music, dance, radio, television, film, etc), and technology. It is not restricted by language, beliefs, customs and traditions, food, dress, financial/educational status, background, or ethnic group. It is expressed through media such as radio, television, film, music, etc. Film and popular culture are inseparable. This paper addresses the relationship existing between film and popular culture and their importance to the populace. It also explains how popular culture finds expression through film and the level of impact both concepts make on the audience and society at large. The paper adopts a qualitative descriptive research design with the use of content analysis. Two films are selected to be analysed. Interactionism Theory is adopted as the basis for discussion of the interaction between Popularculture and film. The two films are analysed to show how popular culture is reflected in them and the importance of popular culture in them is discussed. The study found that popular cultural concepts and ideas were reflected in the two films under study.Examples of such findings include ideas like corruption in Nigeria, the conflict between bride-to-be and mother-in-law-to-be, and also the tardiness of the typical Nigerian bureaucracy.
ANCIENT AND MODERN: NEXUS BETWEEN TRADITIONAL ELEMENTS AND NEW CULTURE IN TWO NIGERIAN PLAYS
Authors: J. Oloko, M. , A Prof Osoba, Gabriel
Published: December 2024

Studies in literary and linguistic analysis of culture in Nigerian literary texts are numerous in existing literature. However, there is still the need to fill the gap in comparative literary and linguistic studies of culture in the ancient and modern periods. This study attempts an investigation of the nexus between traditional elements and new culture in Zulu Sofola’s Wedlock of the Gods and Gab Osoba’s The Tortoise and the Money Lender that reflect a society in transition. The paper examines the two texts as literary works that explore the conflict of ideas, values, or traditions in contemporary Nigerian society. Thirty-two excerpts selected from the two texts were subjected to rigorous analysis using J. R. Searle’s pragmatics and J. Austine’s speech act theory. The analysis reveals that linguistic and discursive resources are deployed in the texts to present traditional cultural practices that are being interrogated in the light of modernity and new culture. The paper concludes that African cultural practices that are not in conflict with modernity should be preserved while those that appear bizarreand primitive should be discarded.

Published: December 2024

In traditional economic theories, people are viewed as having perfect knowledge, which is a critique of behavioural finance especially on grounds of cognitive biases. The research aims at determining gender-related cognitive biases in relation to investment among people of Manipur. The research establishes that there are quite noticeable gender-related biases like overconfidence, loss aversion, and anchoring. The research shall adopt a quantitative research design with the target population of 75 participants and the t-tests used in the analysis of the data. According to the research, it was evident that there is evidence of gender differences in overconfidence, loss aversion, and anchoring biases. However, herd behaviour, confirmation and availability do not show significant evidence of gender differences. The implications of these results are for the delivery of effective financial literacy and education.

Published: December 2024

Surgical patients often experience psychological distress that can hinder their recovery. Mind-body interventions (MBIs) delivered by nurses, such as guided imagery and mindfulness exercises, may improve psychological well-being and surgical recovery. This meta-analysis examined the effectiveness of nurse-delivered MBIs on adult surgical patients. A systematic search of PubMed, CINAHL, PsycINFO, and Cochrane Library databases was conducted from January 2013 to November 2024. Randomized controlled trials (RCTs) examining the effects of nurse-delivered MBIs on adult surgical patients were included. Primary outcomes were anxiety, depression, and pain. Secondary outcomes included length of hospital stay, postoperative complications, and medication usage. Random-effects models were used to calculate pooled effect sizes (Hedges' g). Six RCTs met the inclusion criteria, comprising 785 participants. Meta-analysis revealed that nurse-delivered MBIs significantly reduced anxiety (g = -4.09, 95% CI [-6.25, -1.93], p = 0.0002) and depression (g = -3.40, 95% CI [-4.96, -1.85], p < 0.00001) compared to standard care. Significant reductions in postoperative pain (g = -1.77, 95% CI [-2.10, -1.44], p < 0.00001) were also observed. No significant differences were found for length of hospital stay or postoperative complications. In conclusion, nurse-delivered MBIs effectively improve psychological well-being and reduce postoperative pain in adult surgical patients, supporting their integration into routine surgical care.
Drone-Based Adaptive Hybrid Techniques for Improving Face Detection and Recognition
Authors: Alshbatat Abdel Ilah N. , Awawdeh Moath
Published: December 2024

With the rapid development of Unmanned Aerial Vehicle (UAV) related technologies, Drones gained the opportunity to search locations that are dangerous or difficult for humans to reach. In this regard, Drones technology has been widely used to detect and recognize humans on the ground. In order to identify their potential role in counter-terrorism operations, the aim of this research study is to design and develop a reliable aerial system capable of identifying people with a high detection rate. Furthermore, it presents a solution to all challenges that degrade the resolution when query images are taken from high altitudes, different angles, and long distances. In the context of improving the accuracy of facial detection and recognition, two adaptive techniques are proposed: The first approach is to adaptively adjust the Drone’s altitude, speed, and attitude based on two parameters: Ground sampling distance (GSD), and confidence level of the recognized face. The second approach is to adaptively adjust the resolution of images captured by drone based on the size of the detected facial area. Face detection and recognition are done using the Haar Cascade classifier and Local Binary Pattern Histogram (LBPH) algorithm. The entire system was developed, implemented, and tested using a Hexacopter Drone and onboard vision system. The testing results corroborate the system's practicality and demonstrate that the prototype may be simply implemented to track dangerous people with criminal records.

Published: December 2024

The industry has experienced significant advancements in recent years, primarily focusing on smart manufacturing, culminating in the Industry 4.0 (I4.0) revolution I4.0 emphasizes interconnectivity, real time data capture and transmission among machines, autonomy, and machine learning, providing manufacturing companies numerous growth opportunities. The Industrial Internet of Things (IIoT) is a core component of this revolution, becoming integral to each system and increasing complexity due to the vast number of interconnected devices and diverse physical components. The variety of virtual services distributed across the architectural layers of industrial systems (cloud, fog, edge) and the various connection types between IIoT devices introduce security and privacy challenges, which are critical issues for any system incorporating IIoT. To fully leverage IIoT’s potential, addressing these security and privacy concerns is essential. Research and design in this domain are challenging, particularly when creating a simulation environment to study a system’s behavior over time. Despite the extensive research in IoT and the significant benefits of simulation based approaches, there remains a challenge in creating detailed representations from the underlying IoT nodes to the application layer in the cloud, along with the underlying networking infrastructure. To assist researchers and practitioners in overcoming these challenges, we propose the Discrete Event System Specification (DEVS) formalism. DEVS provides a mathematical framework for modeling systems, whether discrete or continuous events, allowing for the simulation of these systems within the DEVS environment. Every system, whether real or conceptual, has a time base, inputs, outputs, and functions to determine the next state, as well as outputs that reflect the current state and inputs. Simulating the system within the DEVS environment allows one to study its behavior to predict and optimize performance patterns.

Published: December 2024

This research discusses the design of character designs in illustration books getting to know DKV for SMA/MA/SMK teenagers. Teenagers need knowledge and information in making plans for the future, one of which starts with preparing to choose the right major in college. This aims to minimize cases of students feeling like they have entered the wrong major. Apart from that, the existence of the DKV sector is still underestimated by some people due to a lack of knowledge about DKV. The method used in this design is a quantitative descriptive and qualitative descriptive data analysis method through interview data, FGD (Focus Group Discussion), observation, questionnaires, and literature study which culminated in the keyword "Deep understanding DKV with the present" and obtained results in the form of 3 design characters representing 2 DKV students and 1 SMA/MA/SMK teenager. Each character is designed with a contemporary design approach in a contemporary form using a flat design drawing style.

A transformative theory-based framework for intermediate phase pre-service language teachers’ application of transformative assessment practices
Authors: Smith Natalie , Holtzhausen Somarie
Published: December 2024

Limited studies illustrate the significance of a transformative perspective on pre-service teachers’ assessment practices during their study in higher education institutions (HEIs). As such, the need to prepare pre-service teachers for the transformative realities of the workplace has been widely acknowledged as a crucial element of contemporary teacher education. Therefore, this conceptual article aims to provide a transformative theory-based elucidation on assessment practices and their application by intermediate-phase pre-service language teachers (IPPLTs).  Having applied transformative learning theory (TLT) and a narrative literature review (NLR), this article proposes a transformative theory-based framework (TTbF) that HEIs can apply to equip IPPLTs with transformative assessment practices (TAPs) during their training and teaching practice sessions. The findings reveal that transformability, transformative-targeted interventions, and adaptive capacity can be valuable takeaways for IPPLTs’ professional development in applying TAPs. The study recommends that IPPLTs consider applying the TTbF to strengthen their ability to implement TAPs in schools.
Digital economy’s role in shaping China’s outward investment in Belt and Road countries
Authors: Tang Wan , Lan Qingxin , Yang Yalin
Published: December 2024

Previous international investment-related literature is less likely to include host country digital economy as an influential factor in the analysis framework. Meanwhile digital economy-related literature mainly focuses on the concept and characteristics of digital economy, and few scholars explore the impact and mechanism of China’s OFDI in the context of digital economy. Based on the theory and mechanism analysis, this article first constructs a comprehensive digital economy indicator system using data from 46 B&R countries from 2004 to 2020 and then constructs extended investment gravity model, technological innovation intermediary impact and trade cost moderating effect to thoroughly investigate the effect and fundamental mechanism of digital economy on China’s OFDI. The conclusions are as follows: First, digital economy indicators’ computation reveals significant disparities among B&R countries. Second, baseline regression finds that B&R countries’ digital economy considerably boosts China’s OFDI. Third, regional heterogeneity reveals that digital economy in ASEAN countries plays a more visible role in boosting China’s OFDI. Fourth, mechanism analysis reveals that B&R countries’ digital economy can encourage China’s OFDI by improving technological innovation and reducing trade costs.
Long-term Dynamical Stability in the Outer Solar System. II. Detailed Secular Evolution of Four Large Regular and Resonant Trans-Neptunian Objects
Authors: Muñoz-Gutiérrez Marco A. , Peimbert Antonio , Pérez-Villegas Angeles
Published: December 2024

The long-term evolution of the outer solar system is subject to the influence of the giant planets, however, perturbations from other massive bodies located in the region imprint secular signatures, which are discernible in long-term simulations. In this work, we performed an in-depth analysis of the evolution of massive objects Eris, 2015 KH162, Pluto, and 2010 EK139 (aka, Dziewanna), subject to perturbations from the giant planets and the 34 largest trans-Neptunian objects. We do this by analyzing 200, 1 Gyr long simulations with identical initial conditions, but requiring the numerical integrator to take different time steps for each realization. Despite the integrator’s robustness, each run’s results are surprisingly different, showing the limitations of individual realizations when studying the trans-Neptunian region due to its intrinsic chaotic nature. For each object, we find orbital variables with well-defined oscillations and limits, and others with surprisingly large variances and seemingly erratic behaviors. We found that 2015 KH162 is a nonresonant and very stable object that experiences only limited orbital excursions. Pluto is even more stable and we found a new underlying constraining mechanism for its orbit; 2010 EK139 is not well trapped in the 7:2 mean motion resonance in the long term and cannot be trapped simultaneously in von Zeipel–Lidov–Kozai resonance; and finally, we found that at present Eris’s longitude of perihelion is stationary, tightly librating around 190°, but unexpectedly loses its confinement, drifting away after 150 Myr, suggesting a missing element in our model.
Mid-infrared Variability in Nearby Galaxies from the MaNGA Sample
Authors: Pai Aashay , Blanton Michael R. , Moustakas John
Published: December 2024

We use mid-infrared variability in galaxies to search for active galactic nuclei (AGN) in the local universe. We use a sample of 10,220 galaxies from the Mapping Nearby Galaxies at Apache Point Observatory survey, part of the Sloan Digital Sky Survey. For each galaxy, we examine its mid-infrared variability in the W2 [4.6 μm] band over 13 years using data from the Wide Infrared Survey Explorer (WISE) All-Sky and Near Earth Objects WISE missions. We demonstrate that we can detect variability signatures as small as about 7% in the rms variation of W2 flux for the majority of cases. Using other AGN signatures of the variable galaxies, such as optical narrow lines, optical broad lines, and WISE W1 − W2 colors, we show that ∼75% of the variables show these additional AGN signatures, indicating that the bulk of these cases are likely to be AGN. We also identify seven galaxies that have light curves characteristic of tidal disruption events. We present here a publicly available catalog of the light-curve variability in W2 of these galaxies.
Exploring Lenticular Galaxy Formation in Field Environments Using NewHorizon: Evidence for Counterrotating Gas Accretion as a Formation Channel

Published: December 2024

The formation pathways of lenticular galaxies (S0s) in field environments remain a matter of debate. We utilize the cosmological hydrodynamic simulation, NewHorizon, to investigate the issue. We select two massive star formation quenched S0s as our main sample. By closely tracing their physical and morphological evolution, we identify two primary formation channels: mergers and counterrotating gas accretion. The former induces central gas inflow due to gravitational and hydrodynamic torques, triggering active central star formation, which quickly depletes the gas of the galaxy. Counterrotating gas accretion overall has a similar outcome but more exclusively through hydrodynamic collisions between the preexisting and newly accreted gas. Both channels lead to S0 morphology, with gas angular momentum cancellation being a crucial mechanism. These formation pathways quench star formation on a short timescale (<Gyr) compared to the timescales of environmental effects. We also discuss how counterrotating gas accretion may explain the origin of S0s with ongoing star formation and the frequently observed gas–star misaligned kinematics in S0s.
Halfway to the Peak: The JWST MIRI 5.6 μm Number Counts and Source Population
Authors: Sajkov Leonid , Sajina Anna , Pope Alexandra , Alberts Stacey , Armus Lee , Farrah Duncan , Lin Jamie , Marchesini Danilo , McKinney Jed , Veilleux Sylvain , Yan Lin , Young Jason
Published: December 2024

We present an analysis of eight JWST Mid-Infrared Instrument (MIRI) 5.6 μm images with 5σ depths of ≈0.1 μJy. We detect 2854 sources within our combined area of 18.4 arcmin2. We compute the MIRI 5.6 μm number counts, including an analysis of the field-to-field variation. Compared to earlier published MIRI 5.6 μm counts, our counts have a more pronounced knee, at roughly 2 μJy. The location and amplitude of the counts at the knee are consistent with the Cowley et al. model predictions, although these models tend to overpredict the counts below the knee. In areas of overlap, 84% of the MIRI sources have a counterpart in the COSMOS2020 catalog. These MIRI sources have redshifts that are mostly in the z ∼ 0.5–2, with a tail out to z ∼ 5. They are predominantly moderate to low stellar masses (108–1010
M
⊙) main-sequence star-forming galaxies, suggesting that with ≈2 hr exposures, MIRI can reach well below M
* at cosmic noon and reach higher mass systems out to z ∼ 5. Nearly 70% of the COSMOS2020 sources in areas of overlap now have a data point at 5.6 μm (rest-frame near-IR at cosmic noon), which allows for more accurate stellar population parameter estimates. Finally, we discovered 31 MIRI-bright sources not present in COSMOS2020. A crossmatch with IRAC channel 1 suggests that 10%–20% of these are likely lower mass (M
* ≈ 109
M
⊙), z ∼ 1 dusty galaxies. The rest (80%–90%) are consistent with more massive but still very dusty galaxies at z > 3.

Dust-obscured galaxies (DOGs) containing central supermassive black holes (SMBHs) that are rapidly accreting (i.e., having high Eddington ratios, λ
Edd) may represent a key phase closest to the peak of both the black hole and galaxy growth in the coevolution framework for SMBHs and galaxies. In this work, we present a 68 ks XMM-Newton observation of the high-λ
Edd DOG J1324+4501 at z ∼ 0.8, which was initially observed by Chandra. We analyze the XMM-Newton spectra jointly with archival Chandra spectra. In performing a detailed X-ray spectral analysis, we find that the source is intrinsically X-ray luminous with

. We further utilize UV-to-IR archival photometry to measure and fit the source’s spectral energy distribution to estimate its host-galaxy properties. We present a supplementary comparison sample of 21 X-ray luminous DOGs from the XMM-SERVS survey with sufficient (>200) 0.5–10 keV counts to perform a similarly detailed X-ray spectral analysis. Of the X-ray luminous DOGs in our sample, we find that J1324+4501 is the most remarkable, possessing one of the highest X-ray luminosities, column densities, and star formation rates. We demonstrate that J1324+4501 is in an extreme evolutionary stage where SMBH accretion and galaxy growth are at their peaks.

Published: December 2024

Magnetopause reconnection is a fundamental mechanism for mass and energy transfer in terrestrial planetary systems. Unlike Earth, Mars lacks a global magnetic field and instead has localized crustal magnetic fields, which can create structures morphologically similar to a scaled-down intrinsic magnetosphere, potentially forming mini-magnetospheres. In this study, we investigate reconnection in Martian mini-magnetospheres on the dayside, analyzing key characteristics of the reconnecting current sheet, and the associated ion escape rate, and comparing these features to reconnection events at the induced magnetopause documented in previous studies. Our observations reveal that, in the subsolar region, the thickness of the Martian mini-magnetopause is comparable to the upstream proton inertial length and the convective gyroradius of the magnetosheath solar wind. However, at higher solar zenith angles, this thickness increases to several times these characteristic lengths. Reconnection-driven ion escape rates at the induced magnetopause are at least 1 order of magnitude greater than those associated with mini-magnetopause reconnection. These findings provide new insights into reconnection processes at Martian boundary layers.

Published: December 2024

En France, on compte six cent dix mille orphelins de moins de 25 ans. Ces situations ont des répercussions multiples (i.e. économiques, sociales, psychologiques, comportementales), notamment en milieu scolaire. Pourtant, la littérature est peu développée concernant la posture des enseignants et leurs pratiques en la matière. Cette étude a pour objectif de documenter, de façon exploratoire, leurs représentations des orphelins, comment ils appréhendent leurs besoins et les incidences sur leur posture professionnelle. Vingt-cinq entretiens ont été réalisés auprès d’enseignants confrontés à la scolarisation d’un ou plusieurs élèves orphelins. Une analyse thématique de contenu a été réalisée. Les résultats révèlent combien la situation s’avère déstabilisante et suscite des ambivalences émotionnelles supposant des ajustements de nature plus relationnelle que pédagogique. Cette expérience marquante, car confrontant à la finitude, apparaît néanmoins créatrice de sens et d’un lien particulier avec l’élève.
À quels besoins de l’orphelin répond un groupe d’accompagnement au deuil ?
Authors: Molinié Magali
Published: December 2024

Est-il possible d’identifier les réponses qu’apportent les groupes d’accompagnement du deuil aux besoins des enfants orphelins ? Cette étude explore ce que la littérature recense comme besoins fondamentaux des enfants, en précisant en quoi le décès d’un parent vient particulièrement mettre à mal la réponse à certains d’entre eux. Elle examine ensuite les facteurs communs des interventions de soutien groupal au deuil des orphelins tels que récemment recensés par Kentor et Kaplow (2020). La mise en regard de ces deux ensembles éclaire en quoi ces groupes de soutien répondent en effet à des besoins de sécurité, de régulation émotionnelle, d’identité… Ils répondraient bien à des besoins fondamentaux, mais également à des besoins spécifiques liés aux difficultés de l’orphelinage. Ces hypothèses invitent à des études confirmatoires de terrain.
The Effects of Eliminating Idiomatic American English From High-Stakes Nursing Examinations
Authors: Parker Timothy M. , O'Connell Kathleen
Published: December 2024

Background

In the United States, English for Speakers of Other Languages (ESOL) health care providers are important to the nursing workforce but often face challenges when taking the NCLEX-RN examination. This study evaluated the effects of removing slang and words with multiple meanings from high-stakes examination questions.

Method

This study used a quantitative, experimental posttest-only control group design and included a convenience sample of 169 nursing students from a college in southern Florida.

Results:

Nursing students performed significantly better on the experimental (
M
= 79.9 [7.48]) than on the control examination (
M
= 75.08 [10.51]),
t
(151.8) = 2.973,
p
= .003. Students with low language acculturation scores achieved significantly higher scores on the experimental (
M
= 81.48 [
SD
= 6.05]) versus the control examinations (
M
= 72.21 [10.09]),
t
(60.9) = 4.975,
p
= .001.

Conclusion

Modifying examination questions linguistically can help ESOL nursing students perform better and aid examination creators to design bias-free tests.

A novel approach to Lyapunov stability of Caputo fractional dynamic equations on time scale using a new generalized derivative
Authors: Ineh Michael Precious , Akpan Edet Peter , Nabwey Hossam A.
Published: December 2024

In this work, we introduced a generalized concept of Caputo fractional derivatives, specifically the Caputo fractional delta derivative (Fr$ \Delta $D) and Caputo fractional delta Dini derivative (Fr$ \Delta $DiD) of order $ \alpha \in (0, 1) $, on an arbitrary time domain $ \mathbb{T} $, which was a closed subset of $ \mathbb{R} $. By bridging the gap between discrete and continuous time domains, this unified framework enabled a more thorough approach to stability and asymptotic stability analysis on time scales. A key contribution of this work was the new definition of the Caputo Fr$ \Delta $D for a Lyapunov function, which served as the basis for establishing comparison results and stability criteria for Caputo fractional dynamic equations. The proposed framework extended beyond the limitations of traditional integer-order calculus, offering a more flexible and generalizable tool for researchers working with dynamic systems. The inclusion of fractional orders enabled the modeling of more complex dynamics that occur in real-world systems, particularly those involving both continuous and discrete time components. The results presented in this work contributed to the broader understanding of fractional calculus on time scales, enriching the theoretical foundation of dynamic systems analysis. Illustrative examples were included to demonstrate the effectiveness, relevance, and practical applicability of the established stability and asymptotic stability results. These examples highlighted the advantage of our definition of fractional-order derivative over integer-order approaches in capturing the intricacies of dynamic behavior.
An inherently discrete–time $ SIS $ model based on the mass action law for a heterogeneous population
Authors: Choiński Marcin
Published: December 2024

In this paper, we introduce and analyze a discrete–time model of an epidemic spread in a heterogeneous population. As the heterogeneous population, we define a population in which we have two groups which differ in a risk of getting infected: a low–risk group and a high–risk group. We construct our model without discretization of its continuous–time counterpart, which is not a common approach. We indicate functions that reflect the probability of remaining healthy, which are based on the mass action law. Additionally, we discuss the existence and local stability of the stability states that appear in the system. Moreover, we provide conditions for their global stability. Some of the results are expressed with the use of the basic reproduction number $ \mathcal{R}_0 $. The novelty of our paper lies in assuming different values of every coefficient that describe a given process in each subpopulation. Thanks to that, we obtain the pure population's heterogeneity. Our results are in a line with expectations – the disease free stationary state is locally stable for $ \mathcal{R}_0 < 1 $ and loses its stability after crossing $ \mathcal{R}_0 = 1 $. We supplement our results with a numerical simulation that concerns the real case of a tuberculosis epidemic in Poland.
Concevoir un dispositif numérique à 360° pour une expérience augmentée des œuvres au musée
Authors: Thiburce Julien , Doulfaquar Sofiane , Lascar Justine
Published: December 2024

Cet article explore le potentiel d’un dispositif à 360° pour documenter l’exposition permanente du Palais des Beaux-Arts de Lille et offrir un accès numérique aux peintures exposées, en les reliant à d’autres documents fonctionnant comme autant de paratextes (à propos d’une œuvre) et d’intertextes (d’autres œuvres). Nous considérerons ce dispositif à 360° comme un moyen de réduire et d’interroger les frontières entre l’œuvre d’art et ces autres documents. Un des enjeux consistera à problématiser les différentes formes d’implémentation et de (re)médiation des peintures dans le musée lui-même et en contexte numérique, notamment sous l’angle de leurs dimensions matérielles et symboliques.
L’application numérique Sésame : une fabrication inédite de l’image du patrimoine rural religieux ?
Authors: Cailloux Marianne
Published: December 2024

Les nouvelles technologies numériques sont mobilisées pour faciliter l’accès aux biens culturels matériels, notamment à travers des expérimentations d’applications comme guide touristique et accès aux services de visite patrimoniale. Certaines innovent dans la mise en interface des publics avec les objets culturels via la fabrication de nouvelles images. Est ici étudié le projet Sésame, pour comprendre l’articulation entre la visite physique (expérience authentique), la (ré-)appropriation d’une identité visuelle et les enjeux liés aux technologies numériques. Les substituts visuels proposés de différents projets questionnent la capacité d’une stratégie de communication principale à activer une réelle expérience de visite distanciée.
L’engagement des artistes hip-hop à l’ère des réseaux socionumériques et de Black Lives Matter
Authors: Djavadzadeh Keivan
Published: December 2024

Cet article met en évidence un engagement fort et en partie renouvelé des artistes hip-hop au tournant des années 2010, en lien avec l’essor des réseaux socionumériques. Déterminé·es à porter Obama au pouvoir en 2008, un grand nombre d’artistes ont témoigné d’un engagement partisan inédit à l’époque. Par la suite, lorsqu’un mouvement de contestation de grande ampleur s’est fait jour pour protester contre les violences policières et le sort fait aux personnes noires aux États-Unis, plusieurs artistes de premier plan ont mis leur notoriété et leur visibilité en ligne au service de la médiatisation du mouvement Black Lives Matter.
