Stony coral tissue loss disease (SCTLD) affects at least 22 Western Atlantic coral species and presents as focal or multifocal lesions, which swiftly expand across the colony, resulting in rapid tissue loss and mortality. Previous histopathological examinations have noted necrosis, body wall breakage, gastrodermal separation, exocytosis, and vacuolization of the symbiont as pathological signs; however, the same signs are present to some degree in otherwise apparently healthy coral tissues processed for histology. Here, we quantify the degree of symbiont vacuolization, symbiont size change, exocytosis, and gastrodermal separation in apparently healthy and diseased coral tissues of eight coral species in association …

Shadowable Diffeomorphisms With Dominated Splitting, Naoya Sumi

Journal of Stochastic Analysis

We study the shadowability for diffeomorphisms with dominated

splitting. In this paper we show that if a diffeomorphism f has a periodic

saddle q whose unstable manifold is compatible with dominated splitting in

some sense and if f is shadowable, then any other periodic point p has a large

local stable set. Our result does not require the hyperbolicity of p.

On A Remark Of De Gennes Concerning Three-Dimensional Polyelectrolytes, Shiquan Li, Carl Mueller

Journal of Stochastic Analysis

This work is inspired by a remark of de Gennes [3] about polyelectrolytes, which are charged polymers. A common model for a polymer is a self-avoiding or self-repelling random walk or Brownian motion. For polyelectrolytes, the repelling potential is the Coulomb potential arising from pairs of charged particles. We show that in the continuous case of a Brownian motion in three dimensions, the spread of the polymer, in particular the radius of gyration of a polyelectrolyte of length T grows linearly with T, up to logarithmic corrections.

Identité Ambiguë, Mémoire Traumatisée, Et Discours Postcolonial Dans Petit Pays De Gaël Faye, Israel Adégòkè Owóṣení

Tête à Tête: Journal of Francophone Studies

Les écrits autofictifs et semi-autobiographiques de la littérature postcoloniale francophone sont encore à explorer et à discourir, surtout dans le contexte littéraire du XXIe siècle où apparaissent des motifs récurrents et nouveaux tels que l’ambiguïté culturelle, l’hybridité, l’altérité, l’inclusion, la liminalité, le traumatisme et l’effet négatif souillé du postcolonialisme à la mémoire dans une nouvelle ère. Ainsi, cette étude est conçue pour examiner l’ambiguïté identitaire de Gaby et les legs de la colonisation émanant des conflits intertribaux, de la guerre, du génocide et de la violence, qui ont largement miné la perception psychologique du héros - Gaby.

Cette étude a …

Elle désigne un processus économique et politique qui a le but de rassembler des économies, des cultures et des sociétés en un monde. Cette communication vise à explorer l’efficacité de la traduction au sein des organisations internationales comme la Communauté …

Beyond Words: Semiotic Decoding Of Rẹ́Rẹ́Rún (Catastrophe Au Rendez-Vous) By Ọládẹ̀Jọ Òkédìjí And The Rich Tradition Of Yorùbá Theater, Nafiu O. Oloore Mr

Tête à Tête: Journal of Francophone Studies

Many researchers have focused on analysing novels, poems, and drama in the French language while neglecting certain subgenres. Although numerous studies have been conducted on semiotic analysis in French, little effort has been made to analyze Yorùbá drama. Thus, this study aims to provide a semiotic analysis of Rẹ́rẹ́rún (Catastrophe au rendez-vous) by Ọládẹ̀jọ Òkédìjí. This study adopts a qualitative research approach and textual explanation as its methodology. The semiotics theory proposed by Ferdinand de Saussure is employed as the theoretical framework. Following the qualitative method, twenty signs relevant to this study were selected for interpretation. Semiotics is chosen because …

L’Éducation, Un Chemin Inévitable De L’Altérité À L’Inclusion; Un Récit De La Femme Africaine Dans Aya De Yopougon(1-3) De Marguerite Abouet Et Clément Oubrerie, Nkonye Lolita Nmorka

Tête à Tête: Journal of Francophone Studies

Le patriarcat en Afrique, ancré dans la domination masculine et la subjugation féminine, joue un rôle intellectuel depuis quelque temps. Cependant, la phase des mécontentements au sujet de la marginalisation des femmes s’efface progressivement, vu que le discours féminin s’oriente vers une revalorisation visant une inclusion constructive pour l’évolution meilleure de la société. Cette étude se concentre sur l’éducation des filles comme un déclencheur puissant pour le changement de paradigme nécessaire, passant de la relégation et de l’altérité à des réalisations monumentales et des représentations sociales remarquables qui offrent à la femme les connexions nécessaires pour s’épanouir. En appliquant la …

Les Voix Féminines Contre La Domination Patriarcale : Analyse De Rebelle De Fatou Keïta Et Modukpè, Le Rêve Brisé D’Adélaïde Fassinou, Ganiyat Omotola Adeniran

Tête à Tête: Journal of Francophone Studies

La littérature africaine contemporaine constitue un espace privilégié pour l’expression des voix féminines longtemps marginalisées dans un contexte dominé par le patriarcat et les traditions contraignantes. Le présent article propose une étude des romans Rebelle (1998) de Fatou Keïta et Modukpè, le rêve brisé (2000) d’Adélaïde Fassinou. Ces deux récits mettent en lumière les mécanismes d’assujettissement des femmes africaines à travers des pratiques comme l’excision, le mariage forcé, la résignation sociale et les interdits religieux. En mobilisant une approche féministe africaine, l’analyse montre que les héroïnes Malimouna et Modukpè incarnent deux trajectoires contrastées : la révolte et la quête d’autonomie …

Une Analyse Intersectionnelle De L'Albinisme Dans L'Instinct De Survie D'Éveline Mankou Et Ses Implications Contemporaines, Gracious Ojiebun, Eiloghosa Enogiomwan

Tête à Tête: Journal of Francophone Studies

Grâce à l'inclusion numérique, l'éducation devient plus interactive, accessible et inclusive, néanmoins, les enfants atteints d'albinisme en sont souvent exclus en raison de préjugés socio-culturels, de l'écart numérique et des barrières sociales systémiques. L'article explore comment les liens entre la culture, la géographie, la religion, le genre et le statut socio-économique peuvent conduire à une marginalisation violente en se servant d'une évaluation critique de L'instinct de survivre d'Evline Mankou, et en utilisant la théorie de l'intersectionnalité de Crenshaw, 1989.

Le roman dépeint un monde où la superstition et les traditions patriarcales condamnent un enfant atteint d'albinisme, tout en offrant un …

Voix Proverbiales Et L'Esthétique Socioculturelle : Les Proverbes Africains Dans La Trilogie De Kouta De Massa Makan Diabate, Ademola Malick Adebayo, Israel Adégòkè Owóṣení

Tête à Tête: Journal of Francophone Studies

Dans les traditions orales africaines, les proverbes sont des paroles condensées de sagesse, mot d'esprit, de raisonnement social et d'esthétique culturelle. La véritable littérature africaine est l’oralité et elle démontre la richesse linguistique, la complexité culturelle et l’esthétique de la parole à travers les proverbes, les chansons, les épopées, les mythes et les légendes ainsi de suite. L’oralité reflète la richesse linguistique et l’identité culturelle du continent noir. Cependant, les proverbes sont des transporteurs particuliers de la sagesse, la morale, la valeur, les codes sociaux et la croyance d’une société donnée. Dans la trilogie de Massa Makan Diabaté, les proverbes …

L’Insécurité Linguistique Selon La Perspective Des Élèves D’Immersion Française En Saskatchewan, Olushola Adedeji, Michael Akinpelu

Tête à Tête: Journal of Francophone Studies

Cet article examine l’insécurité linguistique (IL) chez des élèves d’immersion française (IF) en Saskatchewan en s’appuyant sur la sociolinguistique pour le changement. À partir d’un devis mixte (un questionnaire à large échelle auprès d’élèves de 7e–12e année et des groupes de discussion focalisés avec des élèves de 11e–12e année), l’étude décrit les différentes manifestations de l’IL, ses causes et ses effets sur les élèves tout en recensant des stratégies d’adaptation. Les résultats de l’étude montrent que l’IL est moins liée à une compétence linguistique objective qu’à des conditions sociales et pédagogiques modifiables. Des recommandations concrètes sont proposées, notamment la légitimation …

Blending Oral Tradition And New Media In Digital Storytelling In Francophone Africa, Moses Chibueze Opara Odogwu

Tête à Tête: Journal of Francophone Studies

This paper investigates the dynamic convergence of oral tradition and new media within the context of digital storytelling in Francophone Africa. Grounded in age-old practices of communal narratives and cultural transmission, oral storytelling has experienced a resurgence through digital platforms, including social media, Tiktok, podcasts, and multimedia productions. This integration facilitates the preservation, revitalisation, and worldwide dissemination of indigenous narratives while promoting vibrant cultural dialogues across different generations. The study analyses how digital storytelling incorporates traditional African oral forms with modern technologies to develop hybrid narratives that transcend local limitations. It also tackles important issues that influence the changing landscape, …

Femo Loquens: Gendered Memory, Afrosofian Thought, And The Speaking Woman In Present-Day Burkina Faso, Diweng Mercy Dafong

Tête à Tête: Journal of Francophone Studies

In order to analyze how female Burkinabè writers and filmmakers contribute to the decolonial endeavor of recovering knowledge, voice, and historical agency following colonial disruption, this paper introduces the idea of femo loquens, a gendered extension of homo loquens as theorized by François Ngoa Kodena. I contend that fiction makers like Apolline Traoré in her movie Sira, Monique Ilboudo in her novel Carrefour des veuves, and Roukiata Ouedraogo in herr novel Le petit mari serve as sofian thinkers whose artistic creations interact with gendered memory and postcolonial realities, drawing on Kodena's Afrosofian philosophy, which emphasizes epistemic plurality, cosmological rootedness, …

L'Exploration Des Figures De Style Dans Maeva Et Les Nuages Du Passé De Fatou Fanny-Cissé, Oladeji Olayiwola Nureni Mr

Tête à Tête: Journal of Francophone Studies

Cette étude examine la figure de style dans les romans contemporains de Fatou Fanny Cissé, Maéva et Les nuages du passé, dans le contexte de la littérature francophone africaine. En s'appuyant sur des critiques littéraires récentes, l'analyse s'inscrit dans une perspective décoloniale, s'interrogeant sur le rôle des figures de style dans la tension entre oralité et écriture, ainsi qu'entre esthétique et engagement politique. L'approche qualitative repose sur une analyse stylistique des deux œuvres, en intégrant des théories de la stylistique textuelle, de la critique postcoloniale et féministe. Les figures de style, telles que métaphores, ironies et personnifications, sont étudiées pour …

Contextualizing Inclusion And Connection In An Absurd World: An Analysis Of Albert Camus’ The Plague, Peter Akongfeh Akongfeh Agwu Ph.D, Peace Onwanua Ph.D., John Ogidi Acha

Tête à Tête: Journal of Francophone Studies

Scholars have extensively analyzed Albert Camus’s The Plaque, while interpreting its narrative through existential and absurdist lenses. However, little literature is recorded on how the novel contextualizes themes of inclusion and human connection amidst an absurd world. This study addresses this gap by examining the dynamics of solidarity and shared resistance among the characters within the framework of Camus’s philosophy of the absurd. The aim is to ex-ray how Camus reconciles the tension between the absurd and the human need for meaning through collective action and emotional bonds. A qualitative methodology is employed, involving a close textual analysis of the …

The French Revolution And Napoleon: The Beginnings Of A Modern World Order, S Trent Dunkin

Tête à Tête: Journal of Francophone Studies

The French Revolutionary and Napoleonic periods, roughly 1789 to 1815, witnessed the fall of the Ancien Régime in France and the foundation of the French Republic. However, this larger period can be divided into three smaller periods: (1) the French Revolutionary Period (1789-1799); (2) the Napoleonic Era (1799-1814); and (3) the Congress of Vienna (1814-1815). This article discusses these three periods individually and their respective contributions that helped to usher in a political order more familiar to the contemporary world. Specifically, this article will explore the following things: The Declaration of the Rights of Man and the Citizen, the …

Digitalverse And The African Narratives: Ai As A New Platform For African Cultural Preservation, Mudasiru Babatunde Sulaiman Mr, Tajudeen Salaudeen

Tête à Tête: Journal of Francophone Studies

Abstract

This article delves into the concept of digital universe as a transforming digital system for the preservation of African culture, with a target on the unique role of artificial intelligence (AI) as a means of storytelling and cultural continuity. For long, there have been problems of availability of sustainable digital infrastructure where African storytelling can be preserved. This study therefore examines the intersection of AI and African storytelling through emerging digital projects, virtual storytelling spaces, and tools that digitize and translate African languages and oral traditions. It argues that AI not only expands the reach of African cultural narratives, …

Cultural And Social Inclusion In Sexe Et Mensonges: La Vie Sexuelle Au Maroc By Leïla Slimani: A Critical Perspective, Juliet N. Elikwu Dr.

Tête à Tête: Journal of Francophone Studies

Several published studies on Leïla Slimani's Sexe et Mensonges: La Vie sexuelle au Maroc have extensively examined the themes of sexual taboos and the challenges facing women in Moroccan society. But, limited attention has been given to her portrayal of cultural and social inclusion through the testimonies and narratives of marginalized women in academic discourse. This study seeks to analyze the dynamics of inclusion and exclusion within the framework of cultural norms and patriarchal structures depicted in the work. The study draws on a qualitative methodology centered on close textual analysis. The theoretical framework integrates Michel Foucault’s concepts of power …

Volatile Evidence At Scale: Forensically Sound Preservation And High-Performance Memory Forensics For Containers And Ros-Based Robots, Taha Gharaibeh Ph.D.

LSU Doctoral Dissertations

Volatile memory holds evidence that reaches persistent storage rarely or never. Containers and robots destroy that evidence as a matter of routine operation rather than through adversarial action, and memory forensic tooling was built for neither platform. This dissertation develops and evaluates a memory-centered approach spanning acquisition, analysis efficiency, and robot forensics, and demonstrates that volatile evidence can be reliably preserved and analyzed at scale across containers and ROS-based robots.

First, we measure why memory forensic analysis is slow. Benchmarking the Volatility Framework across four Python runtimes on 14 memory samples totaling 173 GB shows that PyPy is 15 to …

More Than Just Blocks: Supporting Development Through Block Play In Early Childhood, Stephanie Szanter, Carrie L. Ota

Spark! Innovations in Early Childhood Education: A Research-to-Practice Journal for Educators

Block play is much more than a classroom center; it is a place where children explore ideas, solve problems, communicate, and work together in meaningful ways. This article examines how block play supports children’s social-emotional, cognitive, physical, and language development through hands-on experiences that feel natural and engaging. Using classroom examples and current research, the article highlights how block play changes over time, how teachers can thoughtfully support and extend children’s thinking, and how simple adjustments to materials and setup can deepen learning. Rather than requiring elaborate activities, strong block play environments grow from careful observation, responsiveness, and an understanding …

When Children Cook: Food Experiences As Inquiry, Identity, And Learning, Marian S. Castillo, Carrie L. Ota

Spark! Innovations in Early Childhood Education: A Research-to-Practice Journal for Educators

This article explores the transformative potential of integrating cooking experiences into early childhood classrooms, arguing that food preparation offers much more than a simple activity. By drawing on classroom narratives such as shared meal preparation and spontaneous scientific inquiry this piece illustrates how cooking serves as a catalyst for wonder, problem-solving, and collaboration. It highlights how food-based activities naturally bridge home and school environments, fostering a sense of belonging and cultural identity among young learners. Grounded in developmentally appropriate practice, this article examines the teacher’s role in facilitating these experiences, emphasizing the importance of responsive planning, observation, and valuing the …

More Than Storytime: Intentional Read-Alouds For Literacy Instruction And Formative Observation, Shelia Tate

Spark! Innovations in Early Childhood Education: A Research-to-Practice Journal for Educators

Read-alouds have long been valued in early childhood classrooms for promoting engagement, enjoyment, and a love of reading. When intentionally planned, they can also reinforce foundational literacy skills and provide formative information about student understanding. This article examines how early childhood educators can move read-alouds beyond a familiar classroom routine by connecting them to specific literacy objectives and using student responses to guide subsequent instruction. The IPAQ process (Intentional Choice, Preplanning the Focus, Anticipating Misconceptions, and Questioning and Responses for Formative Observation) provides a practical framework for planning purposeful read-alouds. Classroom examples illustrate how teachers can use planned interactions and …

This article provides practical ways to support responsive and initiating joint attention in infancy which are fundamental to cognitive and social development.

On The Existence, Uniqueness And Stability Of Solutions Of Sdes With State-Dependent Variable Exponent, Mustafa Avci

Journal of Stochastic Analysis

We study a time-inhomogeneous nonlinear SDE with drift and diffusion governed by state-dependent variable exponents. This framework generalizes models like the geometric Brownian motion (GBM) and the constant elasticity of variance (CEV), offering flexibility to capture complex dynamics while posing analytical challenges. Using a fixed-point approach, we prove existence and uniqueness, analyze higher-order moments, derive asymptotic estimates, and assess stability. Finally, we illustrate an application where Poisson’s equation admits a probabilistic representation via a timehomogeneous nonlinear SDE with state-dependent variable exponents.

Companion Matrices Associated To Stochastic Matrices, Andreas Boukas, Philip Feinsilver

Journal of Stochastic Analysis

Starting with a stochastic matrix, we study the behavior of powers of an associated companion matrix, which has the same characteristic polynomial as the original matrix. In general the companion matrix will have negative entries while maintaining rowsums equal to 1. We will find the growth rate even if the Ces`aro limit of the sums of the companion matrix diverge. Surprisingly, in the irreducible aperiodic case the powers of the companion matrix will converge even though the norm of the matrix exceeds 1 and it has possibly negative entries.

Z+-Valued Additive Processes In Law With Nonnegative Increments, Nadjib Bouzar

Journal of Stochastic Analysis

The goal of this article is to study in depth the subclass of Z+- valued additive processes in law with nonnegative increments. We establish key distributional properties of these processes and obtain some existence results under a variety of conditions. We show that they form a subclass of the family of inhomogeneous Markov chains with spatial homogeneity. We extend the notion of factoring introduced by Sato (2004, [9]) for Rd-valued additive processes in law to their Z+-valued counterparts with nonnegative increments. We give a sufficient condition for the existence of a factoring for these processes. Lastly, we obtain their representation …

Design And Fabrication Of 3d Bioprinted Scaffold: Experimental And Machine Learning Methods, Mohan K. Dey

LSU Doctoral Dissertations

The development of reliable hydrogel-based scaffolds for extrusion bioprinting remains limited by the poor structural fidelity of low-viscosity bioinks and the lack of robust, high-throughput quality evaluation methods. This dissertation can resolve such challenges by developing the combination of optimized hydrogel formulations, cryogenic-assisted bioprinting, and artificial intelligence (AI)-based scaffold evaluation to the use of tissue engineering and preclinical cancer modelling applications. To assess the rheological behavior, printability, mechanical properties, and biocompatibility of the alginate – gelatin (Alg–Gel) system, a novel system of hydrogel was developed and characterized using Alg–Gel hydrogel system. The 7% alginate, 8% gelatin mixture was found to …

Correlative In Situ Nonlinear Optical Characteriztion Of Plasmonic Colloidal Nanoparticle Growth Dynamics, Stena C. Peterson

LSU Doctoral Dissertations

Colloidal noble metal nanoparticles are of extreme interest as nanomaterials and for the wide variety of their possible applications in nanomedicine. The unique linear and nonlinear optical processes associated with these nanomaterials can be studied using a variety of spectroscopic techniques including extinction, second harmonic generation (SHG), and two-photon fluorescence (TPF) spectroscopy. In order to better understand and optimize these nanomaterials for their desired applications, it is important to investigate the growth and photophysical dynamics associated with gold nanoparticles, silver-gold core-shell (Ag-Au CS) nanoparticles, and gold-silver-gold core-shell-shell (Au-Ag-Au CSS) nanoparticles in addition to how their size, surface morphology, composition. and …

Extreme Geomagnetic Storm Effects On Earth's Radiation Belts Observed By Calet On The International Space Station, Anthony W. Ficklin

LSU Doctoral Dissertations

This dissertation examines changes in Earth's energetic-particle environment using measurements from the Calorimetric Electron Telescope (CALET) on the International Space Station. Although CALET was designed primarily for high-energy cosmic-ray and gamma-ray observations, its count rates provide nearly continuous measurements of particles of ~1 MeV and above. The analysis uses the CHDX, CHDY, and IMC4X channels, which have approximate electron thresholds of $>\!1.5$, $\!>3.4$, and $\!>8.2$~MeV and proton thresholds of $>\!17$, $\!>37$, and $\!>52$~MeV, respectively. Because these measurements do not identify particle species, the observations are interpreted using their geographic and geomagnetic distributions, the relative …
