Economic Evaluation of Oil Reservoir Emulsion Flooding Fluid Formulated with Palm Oil Mill Effluent and Empty Palm Bunch
Authors: Ndem Daniel Oji
Published: January 2025

The cost of obtaining foreign chemicals for EOR operations in the Niger Delta are challenging, principally in the face of surging currency exchange rate. Therefore, this research presents the opportunity of recovering more oil from the country`s depleted reservoirs at a cheaper cost with eco-friendly emulsion fluid. The cost of formulating the emulsion flooding fluid with palm oil mill effluent, and empty palm bunch was compared to the cost of formulating a synthetic emulsion with gear oil and sodium lauryl sulphate. Oil was extracted from palm oil mill effluent using a centrifuge after characterization and surfactant solution was prepared with distilled water and ash from burnt empty fruit bunch, then oil/surfactant emulsion sample was formulated in a ratio 30/70. Furthermore, a synthetic emulsion with gear oil and sodium lauryl sulfate was also formulated in a ratio of 30/70. Two Core samples of evaluated geometry were used in this flooding experiment. These crude oil saturated cores were flooded with water, then followed with then followed by flooding with the locally formulated emulsion, and the synthetic emulsion respectively. The results showed that water flooding in the two core samples recovered 58.3% of oil, while the locally formulated emulsion recovered an incremental 35.2% and 37.5% of oil respectively. Lastly the economic analysis of formulating emulsion flooding fluid using waste materials from palm oil mill, and using synthetic materials were carried out. The results revealed that the net present value of investment in formulating synthetic emulsion is N-499,507,552,185.00, while the net present value of using waste materials from palm oil mill is N 26,940,828,073.20. Investment on the production of emulsion of 30/70 ratio using synthetic materials requires a substantial initial investment and generates consistent negative cash flows, leading to a significant loss of 90.89%, but investment in the production of 30/70 emulsion ratio with oil extracted from palm oil mill effluent and palm bunch ash appears viable, with a relatively small yearly investment, positive cash flows for the 10-year period, and a substantial positive NPV. With payback period of 8.17 years and a Return on investment of 122.35%.

Los síndromes de neoplasia endocrina múltiple (NEM) incluyen NEM1, NEM2 (anteriormente NEM2A), NEM3 (anteriormente NEM2B) y el recientemente identificado NEM4. Las presentaciones clínicas son variadas y a menudo se relacionan con la sobreproducción de hormonas específicas. Comprender la genética de cada síndrome ayuda a determinar los plazos de detección. Los tratamientos para cada manifestación dependen de la ubicación, el riesgo de recurrencia o malignidad, el exceso de hormonas y la morbilidad quirúrgica. El manejo multidisciplinario debe incluir genetistas, asesores genéticos, endocrinólogos y cirujanos en patologías endocrinas.

Synergistic Effect of Different Amounts of Selenomethionine and Encapsulation of Vitamin E and Its Influence in Controlling Vitamin E Release
Authors: Md Lazim Nurul Asmak , Khairuddin Nozieana , Muhamad Ida Idayu
Published: January 2025

The series homologues of tocopherols and tocotrienols that make up vitamin E vary in terms of methyl group location and number of bonds. The body uses vitamin E for several purposes. Unfortunately, vitamin E is unstable and will degrade quickly in water, absorb less readily and have a poor level of bioavailability when exposed to heat, light or air. Selenomethionine, the typical essential trace element form of selenium (Se) produced from animal products, has therefore been added to this study. Freeze-dried technique was used to prepare encapsulation of vitamin E with different amounts of selenomethionine. The effect of different amount of selenomethionine on physicochemical properties and vitamin E release were investigated. The results reveal that when the amount of selenomethionine injected increases, the solubility of vitamin E increases, but the influence on particle size decreases. As a result, the particle dispersion followed the same patterns. After integrating selenomethionine, the encapsulation's zeta potential remains stable. The results of FT-IR and TEM research corroborate this. After adding different amounts of selenomethionine to the surface particles, the surface of the encapsulation was smooth with periforous structure, indicating that the air bubble created after freeze-drying process was impacted by the addition of selenomethionine to the surface particles. Furthermore, the release analysis reveals that the formulation with 0.03 % selenomethionine enhances vitamin E release in simulated intestinal fluid (SIF) better than in simulated gastric fluid (SGF) model, which is consistent with a prior study. It was concluded that adding varying amounts of selenomethionine varied the encapsulation and vitamin E release characteristics. In conclusion, the formulation with 0.03 % selenomethionine is consistent in terms of encapsulation stability and release performance.

O objetivo do estudo foi avaliar a distribuição de tensões em pré-molares endodonticamente tratados restaurados com coroas cerâmicas sob influência ou não da férula e a presença ou não de retentores intrarradiculares. Foram construídos seis modelos virtuais de pré-molar inferior endodonticamente tratado em software de modelagem tridimensional (SolidWorks). As raízes apresentadas foram construídas com (2mm) ou sem férula e com ou sem pino intrarradicular (núcleo metálico fundido, pino de fibra de vidro ou sem pino). Sobre a raiz do dente foi confeccionada uma coroa cerâmica. Os modelos foram considerados isotrópicos, homogêneos e lineares e foram avaliados através do software de análise por elementos finitos Ansys Workbench. Foi aplicada uma carga de 250 N na cúspide vestibular à 45º com o longo eixo do dente. Os dados da tensão máxima principal (σmax) foram obtidos para a raiz e coroa cerâmica. A presença da férula diminuiu as tensões geradas na raiz e na coroa cerâmica. Os modelos restaurados com núcleo metálico fundido apresentaram os maiores valores de tensão na raiz (68,5N), seguidos pelos grupos com pino de fibra e sem pino (62N e 59N, respectivamente). Os modelos que não apresentavam pinos tiveram os maiores valores de tensão na coroa (87N). A férula diminui as tensões na raiz de pré-molares tratados com ou sem pinos intrarradiculares. Pinos metálicos aumentam as tensões na raiz, enquanto a ausência de pinos aumenta as tensões na coroa.
PALAVRAS-CHAVES: Tratamento endodôntico, elementos finitos tridimensionais, coroas cerâmicas.
The Influence of Influencer Marketing and Social Media Marketing on Purchase Decisions with Brand Awareness as an Intervening Variable for TikTok Shop in Generation Z
Authors: Arlana Hidayatullah Aidil , Fadhilah Muinah , Tria Hatmanti Hutami Lusia
Published: January 2025

This study examines the effect of influencer and social media marketing on purchase decisions among Generation Z, mediated by brand awareness, within the TikTok Shop platform. The study addresses the digital marketing shift, where social media is crucial in increasing brand engagement and consumer purchasing behavior. Using quantitative methods, data were collected from 112 Generation Z consumers in Yogyakarta who had experience shopping at TikTok Shop. The analysis employed the PLS-SEM method using SmartPLS 3.0. Results indicate that while social media marketing significantly influences brand awareness and purchase decisions, influencer marketing only positively impacts brand awareness. Furthermore, brand awareness mediated the relationship between social media marketing and purchase decisions but not between influencer marketing and purchase decisions. This highlights the critical role of social media marketing over influencer marketing in driving consumer purchasing decisions on TikTok Shop, especially through brand awareness. The findings suggest marketers should prioritize strategies that enhance social media engagement to strengthen brand presence and drive consumer decisions

Analysis of Factors Influencing Intention to Purchase Natural And Environmentally Friendly Cosmetic Products
Authors: Zaki Bahaiyan Salim , Ridanasti Erlita
Published: January 2025

The popular trend in the global beauty industry has reshaped consumer consumption patterns, including in Indonesia. However, the unsustainable consumption of cosmetic products poses risks to environmental and social sustainability. With the phenomenal growth of the rapidly expanding cosmetic industry, the consumption of cosmetic products has also increased significantly. Unfortunately, this increase has negative environmental impacts and can harm consumer health. This is due to waste from raw materials used in production, product packaging, and chemicals that may pose health risks to consumers. Alternatively, green products have been widely developed and are available in the market. This study aims to examine the factors influencing the purchase intention of natural and eco-friendly cosmetic products among Indonesian consumers. To establish a hypothesis framework, 161 valid questionnaires were collected through purposive sampling in several cities in Indonesia. Data analysis and hypothesis testing were conducted using SmartPLS statistical software. The study results indicate that Indonesian consumers’ purchase intentions for natural and eco-friendly cosmetic products tend to be positively influenced by consumers’ attitudes toward environmental concern, health consciousness, and perceived behavioral control. Additionally, purchase intention positively impacts behavioral intention. These findings provide insights into Indonesian consumers' habits and awareness in choosing natural and eco-friendly cosmetic products.

Authors: Zulkifli Noor Zulki
Published: January 2025

This study aims to analyze the effect of green marketing and sustainability practices on brand equity in the Indonesian e-commerce sector. A quantitative approach with an explanatory research design was used to test the relationship between variables. Data were collected through an online survey using a structured questionnaire from 200 respondents who are e-commerce consumers in Indonesia. The analysis was conducted using Structural Equation Modeling (SEM) to test the direct and indirect effects. The results showed that green marketing has a significant positive effect on brand equity (? = 0.42, p < 0.001). Sustainability practices also have a positive effect on brand equity (? = 0.38, p < 0.004). In addition, sustainability practices are proven to mediate the relationship between green marketing and brand equity with an indirect effect of 0.15 (p = 0.032). These findings indicate that green marketing strategies integrated with sustainability practices can increase consumer loyalty and trust, which ultimately strengthen brand equity. This study provides theoretical contributions to the green marketing and sustainability literature, and offers practical guidance for e-commerce companies to adopt environmentally friendly strategies effectively. Managerial implications include the importance of transparent communication and consistent adoption of sustainability practices to create competitive advantage. This study also opens up opportunities for further exploration in other sectors or with different methods.
Yosel ben Todros: S. Y. Agnon on the Language of Ashkenaz
Authors: Bartal Israel
Published: January 2025

Jews of the Ashkenazi diaspora spoke, read, and wrote in two languages: Hebrew and Yiddish. In his work S. Y. Agnon touched on the historical duality that characterized the German language in the culture of Galician Jews after they were incorporated into the Habsburg empire. The state-sponsored linguistic shift from Yiddish to German, which took place over the course of the nineteenth century in the cities and towns of Galicia, was presented by him in an extremely negative light. This was the source of his hostility to the writer Joseph Perl, whose modern school undermined the socio-linguistic base which had preserved the cultural unity of the Ashkenazi diaspora.
The Linguistic Politics of Jewish Emancipation: Leon Pinsker between German, Yiddish, and Hebrew
Authors: Volovici Marc
Published: January 2025

Leon Pinsker’s 1882
Auto-emancipation!
is widely considered a formative text of Jewish nationalism and a precursor of Zionist ideology. Published in German and aiming to speak on behalf of Russian Jewry, it generated a political and linguistic conundrum over the starkly different conceptions of ‘Jewish emancipation’ in western and eastern Europe, and the implications of these differences. For the Hebrew and Yiddish translators of
Auto-emancipation!
, rendering Pinsker’s text was an opportunity to remould and adapt it to the linguistic and ideological exigencies of its potential readerships. This chapter follows the reception of
Auto-emancipation!
across the Jewish diaspora and theorizes the linguistic politics of Jewish emancipation between 1882 and 1917. It locates the translation choices of Shmuel Leib Zitron, Mendele Moykher Sforim, and Ahad Ha’am within broader political and linguistic contexts.
Sir Toggenburg of the Shtetl: Friedrich Schiller in the East European Jewish Imagination
Authors: Gollance Sonia
Published: January 2025

The German writer Friedrich Schiller was arguably the most important non-Jewish writer for east European Jews. Although these readers revered him even more than they did his contemporary Goethe, they often treated Schiller’s works as middlebrow fiction that was most appropriate for women—as exemplified by ‘Friedrich Schiller’, a 1919 short story by Galicia-born American Yiddish writer Fradel Shtok, which describes the inner life of a young Jewish woman in Galicia who develops an increasingly elaborate fantasy about her favourite German writer as her quiet life is rocked by the forces of modernity. Shtok suggests that an obsession with Schiller comports with a Jewish girlhood in a refined family. As such, this story provides a new perspective on how German literature was viewed—and reclaimed—by Yiddish-speaking Jews.
Jewish Laughter and Jewish Tears: Fascism and Antisemitism in the Joke Pages of the Yiddish Press in 1930s Poland
Authors: Klotz Anne-Christin
Published: January 2025

The Jewish, and especially the Yiddish, press and its historical role as a producer of cartoons and jokes has been largely neglected in scholarship. However, the transformation of news into forms of humour presented the producers of Yiddish newspapers with an alternative way of offering their customers insights into complex issues. Taking the rise of nationalist and antisemitic movements in both Germany and Poland during the 1930s as a case study, this chapter gives an overview on how Jewish humorists of the Warsaw Yiddish press pictured these movements, and how they portrayed the reaction of Jews to various forms of antisemitism. It shows how these humorists saw jokes as weapons against injustice and were part of the widespread Jewish protest against Nazi Germany in Poland.
Solomon Dubno: An East European Maskil and the German Haskalah
Authors: Krzemieñ Zuzanna
Published: January 2025

This chapter proposes to understand the life and works of Solomon Dubno as an example of the Jewish Enlightenment in an east European key. Dubno was born in today’s Belarus and excelled as a grammarian and author and is best known as a contributor to Moses Mendelssohn’s German translation of and commentary on the Hebrew Pentateuch. In contrast to Mendelssohn’s agenda of rapprochement between Jews and non-Jews, Dubno advocated Hebrew literacy for the educated Jewish reading public with an emphasis on the Masorah and including a rejuvenation of Hebrew belles-lettres. The chapter sheds new light on the falling-out between the two authors, on Dubno’s failed project to publish his own commentary on the Pentateuch, and on his Hebrew literary writings.
‘Between us and them there still stands a wall’: German Jews Deported to the Warsaw Ghetto, Spring 1942
Authors: Ferenc Maria , Person Katarzyna
Published: January 2025

This chapter discusses the fate of approximately 3,800 Jewish deportees from various German cities who arrived in the Warsaw ghetto in April 1942. It examines how their arrival challenged the ghetto’s social structures and its internal social dynamics and resulted in the sudden increased involvement of the German administration in the internal affairs of the ghetto. For many Polish Jews, the arrival of German Jews underlined the ‘east European’ character of the Warsaw ghetto, its distance from the Jewish communities of central and western Europe, which still survived at this time, and its increasing closeness to the accelerating process of mass murder in the east.
Collaboration, Complexity, and ‘Integrated History’: Jewish and German Historiographical Representations of Non-German Perpetrators during the Holocaust
Authors: Jockusch Laura , Rossoliński-Liebe Grzegorz
Published: January 2025

Prompted by recent historiographical debates between Polish and German historians over the roles that citizens of countries occupied by or allied with Nazi Germany played in the Holocaust, this chapter explores how Jewish and German historians have written about the complex division of labour between German and local perpetrators. It shows that while Jewish historians—building on their own experiences of persecution—strongly advocated the study of local perpetrators alongside Nazi perpetrators, German historians have long ignored the subject as they focused on German perpetrators, institutions, and sources. Finally it examines how Saul Friedländer’s concept of ‘integrated history’ and the turn to wartime and post-war Jewish sources prepared the ground for a transnational history of the Holocaust that integrates the roles of non-German perpetrators into the historical narrative.
Germans, Jews, and Poles: The Difficult New Beginnings of Jewish Life in Frankfurt am Main after 1945
Authors: Freimüller Tobias
Published: January 2025

The fact that Jewish life re-emerged in Frankfurt am Main after 1945 and that a new Jewish community could be permanently established there was largely because Holocaust survivors, many of them from Poland, were stranded in the American occupation zone of Germany, of which Frankfurt was the centre. Here, one of the largest camps for Jewish displaced persons was established, where an impressive diversity of Jewish life and culture emerged for a few years. Even after emigration to America and Israel became possible in 1948, some displaced persons remained in Germany. This chapter traces how differences between German and east European Jews, the persistent antisemitic attitude of the Germans, and generational conflicts within the Jewish community itself shaped the—ultimately successful—new beginnings of Jewish life in Frankfurt.
Responses to Silence: The Jewish Museums in Berlin and Warsaw
Authors: Meng Michael
Published: January 2025

This chapter addresses the topic of memory cultures in Germany and Poland through a comparative analysis of the Jewish museums in Berlin and Warsaw. It discusses both museums as responses to the ‘silence of death’, a theme introduced through Paul Celan’s poetic reflections on language, silence, and death. Specifically, the chapter examines the question as to whether the Berlin and Warsaw Jewish museums should focus on silence and death: whereas some commentators have argued that both museums should focus on death, others have argued that they should focus on the vibrant life of Jewish culture in central Europe. The chapter concludes by returning to Celan’s reflections on language, silence, and death.
Recovery versus Regression: Identity and Impact in the Post-Holocaust Narratives of Pawlikowski’s
Ida
and Petzold’s
Phoenix
Authors: Weintraub Mendel
Published: January 2025

Since the end of the Second World War countless narrative cinematic efforts have been made to come to terms with the Holocaust’s lasting implications. Christian Petzold’s
Phoenix
and Paweł Pawlikowski’s
Ida
explore issues of national and religious identity in the Holocaust’s aftermath through the fictional stories of female protagonists from Germany and Poland. Both films feature relationships between their protagonists and female companions, who function as surrogates for criticism of Germany’s and Poland’s treatment of Jews during and after the war. Through the depiction of the female companions’ suicides, followed by climactic decisions by their main characters,
Ida
and
Phoenix
offer differing commentary on issues of post-Holocaust national and religious identity. Nevertheless, both ultimately require their protagonists to first leave some element of identity behind as a prerequisite to confronting these issues.
Feminine Discontent and Social Control in Maskilic Comedy and
Sturm und Drang
Melodrama
Authors: Caplan Marc
Published: January 2025

Sturm und Drang
melodrama and maskilic comedy share a number of historical and aesthetic features. The
Sturm und Drang
authors were, like the early maskilim, young intellectuals typically employed as tutors or secretaries to members of the elite. Their critiques of the Enlightenment, therefore, primarily addressed social concerns rather than philosophical, theological, or ideological questions. In particular, they were both preoccupied with the status of women and the dangers posed to their own status as unaffiliated, disenfranchised intellectuals by intellectually and socially independent women. When taken in comparison with
Sturm und Drang
, the maskilic farce can be seen not only as comedy or social critique but also as a revenge fantasy, imparting to a maskilic ideal the social capital and heroic action denied to maskilim in historical reality.
Early Solar System Turbulence Constrained by High Oxidation States in the Oldest Noncarbonaceous Planetesimals
Authors: Yap Teng Ee , Batygin Konstantin , Tissot François L. H.
Published: January 2025

Early solar system (SS) planetesimals constitute the parent bodies of most meteorites investigated today. Nucleosynthetic isotope anomalies of bulk meteorites have revealed a dichotomy between noncarbonaceous (NC) and carbonaceous (CC) groups. Planetesimals sampling NC and CC isotopic signatures are conventionally thought to originate from the “dry” inner disk and volatile-rich outer disk, respectively, with their segregation enforced by a pressure bump close to the water–ice sublimation line, possible tied to Jupiter's formation. This framework is challenged by emerging evidence that the oldest NC planetesimals (i.e., the iron meteorites parent bodies (IMPBs)) were characterized by far higher oxidation states than previously imagined, suggesting abundant (

≳

few weight percent) liquid water in their interiors prior to core differentiation. In this paper, we employ a model for a degassing icy planetesimal (heated by 26Al decay) to map the conditions for liquid water production therein. Our work culminates in threshold characteristic sizes for pebbles composing the said planetesimal, under which water–ice melting occurs. Adopting a model for a disk evolving under both turbulence and magnetohydrodynamic disk winds, and assuming pebble growth is fragmentation limited, we self-consistently translate the threshold pebble size to lower limits on early SS turbulence. We find that if NC IMPBs were “wet,” their constituent pebbles must have been smaller than a few centimeters, corresponding to typical values of the Shakura–Sunyaev α

ν
turbulence parameter in excess of 10−3. These findings argue against a quiescent SS disk (for <10 au), are concordant with astronomical constraints on protoplanetary disk turbulence, and suggest pebble accretion played a secondary role in building our rocky planets.
A new species of Semisulcospira O. Boettger, 1886 (Gastropoda, Cerithoidea, Semisulcospiridae) from Fujian, China with mitochondrial genome and its phylogenetic implications

Published: January 2025

During our investigation of the diversity and phylogeny of the family Semisulcospiridae in China, we have found a presumed new species in mountain streams of Xiamen, Fujian Province on both morphology and molecular evidence. This new species, Semisulcospira egrettasp. nov., is characterized by its thin and smooth shell, retaining about 0.5 mm long embryonic shells in its brood pouch, and by distinctive features of its radular morphology. Phylogenetic analyses of partial sequences of the mitochondrial markers 16S ribosomal RNA (16S) and cytochrome c oxidase subunit I (COI) and complete sequences of the nuclear ribosomal internal transcribed spacer (ITS, including internal transcribed spacer 1, 5.8S ribosomal RNA gene, and internal transcribed spacer 2) supported the distinctiveness of S. egrettasp. nov. from other Semisulcospira species. These analyses consistently placed S. egrettasp. nov. in Semisulcospira confirming its monophyly. Phylogenetic analyses based on just COI and 16S exhibited low resolution rendering the phylogenetic position of the new species within the genus uncertain. In contrast, phylogenetic tree analyses of complete mitochondrial genomes, which include 13 protein-coding genes (PCGs), were better resolved. However, the mitogenome dataset included a more restricted sampling of taxa (16), impeding a detailed exploration of the phylogenetic position of the new species. To address this deficit, we provide seven complete mitochondrial genomes for S. egrettasp. nov., obtained using the genome skimming sequencing method. This study contributes important molecular and genomic data, aiding in the understanding of semisulcospirid phylogeny, and highlights the need for further taxonomic sampling and phylogenomic methods to resolve the evolutionary relationships within Semisulcospiridae.
Politique de la ville : changements de cap et absence de perspectives
Authors: Epstein Renaud
Published: January 2025

Fait inédit dans l’histoire croisée des émeutes et de la politique de la ville, le soulèvement de centaines de quartiers après la mort de Nahel Merzouk, tué par un policier à Nanterre lors d’un contrôle routier le 27 juin 2023, n’a été suivi d’aucune annonce en faveur de cette politique. Venant parachever une dynamique d’effacement des banlieues de l’agenda politique, ce mutisme gouvernemental témoigne de la disparition du caractère réactif de la politique de la ville mais aussi, en creux, de la persistance de sa dimension symbolique. C’est l’analyse que nous propose Renaud Epstein, professeur de sociologie à Sciences Po Saint-Germain-en-Laye / CESDIP.

Sur ce sujet, Labo Cités a souhaité prolonger les réflexions amorcées au cours de second semestre 2023 en organisant en octobre 2024, avec l’association La Cabane de la recherche, un atelier de recherche sur les mutations des métiers de la politique de la ville, au prisme de l’engagement des agents. Ainsi, avec trois docteur·e·s en sociologie, Violette Arnoulet, Alice Daquin et Benjamin Leclercq, des pistes de réflexion et de recherche ont été dessinées sur celles et ceux qui font la politique de la ville aujourd’hui. Jérémy Louis, administrateur de La Cabane de la recherche, revient dans cet article sur l’évolution de ce secteur d’activité, sur les profil des professionnel·le·s, leurs convictions et leurs engagements.
Choréopolice et choréopolitique ou la tâche du danseur
Authors: Maurmayr Bianca , Lepecki André
Published: January 2025

L’élément chorégraphique, dans la notion de « police » de Jacques Rancière, est utilisé pour avancer le concept de « choréopolice », qui peut ensuite être opposé au concept de « choréopolitique » pour redéfinir la « chorégraphie » et la libérer des constructions impératives ou normatives (c’est-à-dire policées) du mouvement. L’idée de Hannah Arendt selon laquelle la liberté est le telos de la politique aide à comprendre comment, dans différents types de chorégraphie (une vidéo de turfing, « Arte de Conducta » de Tania Bruguera et Devotion Study #1 – The American Dancer de Sarah Michelson), la tâche du danseur est de rechercher et de mettre en œuvre cette liberté, encore et encore.

Lorsque le coupé-décalé fait son apparition en 2002, la Côte d’Ivoire est en proie à une crise militaro-politique qui affecte profondément la vie des Ivoiriens. Si le reggae ivoirien s’empare des thèmes de l’ ivoirité et de la xénophobie et évoque la « résistance », la « libération », le « patriotisme », les promoteurs du coupé-décalé s’attachent à promouvoir la joie, l’ enjaillement . Cet article décrit ces luttes non mises en mots ni intellectualisées, mais incarnées et mises en jeu dans des techniques du corps extra-ordinaires.
Twerker dans l’espace public

Published: January 2025

Décrivant la préparation, le déroulement et la réception de flashmobs féministes, Peggy Lecaudé questionne le droit de twerker dans la rue : les attaques qui visent régulièrement cette pratique témoignent des contraintes qui pèsent sur l’usage que les femmes font de leur corps. Exercer le droit de danser dans l’espace public apparaît alors comme une pratique d’émancipation et de réflexion collective, impliquant des questions concrètes sur les normes et les désirs, le regard de l’autre et les rapports de pouvoir.
Mieux accompagner l’installation agricole : proposition d’une typologie des candidats hors cadre familial
Authors: Lataste Dominique
Published: January 2025

Cet article constitue une réponse partielle à la demande de la Cour des comptes d’analyser la déperdition de candidats à l’installation agricole. En appliquant une typologie originale des candidats hors du cadre familial lors d’une mission visant à compléter le diagnostic installation transmission sur un territoire, nous avons cherché à mieux comprendre les difficultés de renouvellement des générations d’agriculteurs et de leur accompagnement. Nous mettons en évidence que les cédants sont souvent enfermés dans leurs représentations, se limitant à une simple catégorisation cadre familial/hors cadre familial. Pourtant, en les invitant à distinguer les candidats selon leur origine et leur expérience à travers notre typologie, de nouvelles perspectives d’accompagnement deviennent possibles.
Utiliser un jeu plateau pour sensibiliser et stimuler l’apprentissage entrepreneurial
Authors: Ducroquet Aude
Published: January 2025

L’innovation pédagogique est essentielle pour répondre aux besoins des nouvelles générations (Lemaitre, 2018). Elle doit aligner objectifs, méthode et connaissances avec le public cible. Nous proposons un jeu de plateau original pour sensibiliser les étudiants à l’entrepreneuriat, abordant 48 notions à travers six étapes clés de la création. Ce jeu est intégré dans un cours d’initiation à l’entrepreneuriat destiné à des étudiants de licence ou de master non orientés vers l’entrepreneuriat. Cet article enrichit le débat sur l’utilisation des jeux dans l’apprentissage, en particulier dans l’éducation entrepreneuriale.

Performing their functions as transporters of oxygen and carbon dioxide in the body, human erythrocytes constantly circulate and are exposed to the constant influence of various substances, including nutrients, drugs, medical devices covered with coatings, etc. Therefore, we aim to investigate the biophysical behavior of erythrocytes obtained from healthy volunteers to observe their morphological type changes, alterations in the zeta potential, the electrical conductivity of the erythrocytes in suspensions, and hemolysis in percentages during cells senescence, both in presence and in absence of natural polyelectrolytes pectin (PE) and chitosan (Chi) in form of multilayer films (PEM-films). Being constructed using the layer–by–layer technique, films are an object of interest of many researchers because of their high potential to be incorporated in biomedicine. By applying optical profilometry, electrophoretic light scattering, and spectrophotometry, we tested the polyelectrolytes for any potential harm on the erythrocytes. Based on our results and the one-way analysis of variance (ANOVA) statistical analysis, we reached the conclusion that the above-mentioned polyelectrolytes were harmlessness; therefore, PE and Chi are suitable substances to implement in the clinical practice in the form of drug delivery carriers and medical devices coatings, thereby directly contacting with the human blood.
Stability analysis and security control of nonlinear singular semi-Markov jump systems
Authors: Song Yang , Yang Beiyan , Wang Jimin
Published: January 2025

This paper mainly studied the stochastic stability and the design of state feedback controllers for nonlinear singular continuous semi-Markov jump systems under false data injection attacks. Based on the Lyapunov function and the implicit function theorem, a basic stochastic stability condition of the system was given to ensure that the nonlinear singular semi-Markov jump system under attack was regular, impulse-free, unique, and stochastically stable. On this basis, the stochastic admissible linear matrix inequality conditions of the system were obtained by using the singular value decomposition of the matrix and Schur's complement lemma. To design the state feedback controller, based on the upper and lower bounds of the time-varying transition probability of the semi-Markov jump system and the singular value decomposition method, the stochastic stable linear matrix inequality condition of the closed-loop system under the false data injection attack was established. Finally, the validity and feasibility of the results were verified by numerical examples.
Dynamical analysis and optimal control of an multi-age-structured vector-borne disease model with multiple transmission pathways
Authors: Liu Huihui , Wang Yaping , Nie Linfei
Published: January 2025

Based on the diversity of transmission routes and host heterogeneity of some infectious diseases, a dynamical model with multi-age-structured, asymptomatic infections, as well as horizontal and vectorial transmission, is proposed. First, the existence and uniqueness of the global positive solution of this model is discussed and the exact expression of the basic reproduction number $ \mathcal{R}_0 $ is obtained using the linear approximation method. Further, we deduce that the disease-free steady state $ \mathcal{E}^0 $ is globally asymptotically stable for $ \mathcal{R}_0 < 1 $, the endemic steady state $ \mathcal{E}^* $ exists and the disease is persistent for $ \mathcal{R}_0 > 1 $. In addition, the locally asymptotically stability of $ \mathcal{E}^* $ is also obtained under some certain conditions. Next, our model is extended to a control problem and the existence and uniqueness of the optimal control by using the Gateaux derivative. Finally, numerical simulations are used to explain the main theoretical results and discuss the impact of age-structured parameters and control strategies on the prevention and control of vector-borne infectious diseases.

Silver Carp Hypophthalmichthys molitrix is an invasive species found throughout the Mississippi River basin. Efforts have been made to control Silver Carp populations through removal programs and movement barrier implementation. Up to date information on diel, seasonal, and annual movements and habitat use by Silver Carp will benefit these efforts. Studies of Silver Carp movement are prevalent in the upper Mississippi River, Ohio River, and tributaries, but rare in tributaries of the lower Mississippi River. Between June 2021 and May 2022, we quantified average movement rates and residency periods of 48 Silver Carp in the free-flowing lower White River and lock-and-dam fragmented lower Arkansas River using passive acoustic telemetry arrays and internal implant acoustic transmitters. We also manually tracked Silver Carp in the two rivers during the four seasons to estimate diel movement rates and use of different habitats. On an annual scale, Silver Carp in the White River moved at faster rates than Silver Carp in the Arkansas River and were recorded more times by acoustic receivers. Diel movement rates varied by season in both rivers but were low overall. Silver Carp used lentic habitats more often than lotic habitats. Overall, results suggest the numerous locks and dams of the McClellan-Kerr Arkansas River Navigation System may limit large-scale, annual movement of Silver Carp in the Arkansas River compared to the White River. Low hourly diel movement rates and high occupancy of lentic habitats also should enable effective harvest of Silver Carp using active gears in those lentic habitats.
Evaluation of Visual Implant Alphanumeric Tagging on Rio Grande Silvery Minnow
Authors: Dunnum Paige M. , Archdeacon Thomas P.
Published: January 2025

Visible implant alphanumeric (VIA) tags can be beneficial in studies where individual fish must be uniquely identifiable and other tagging methods are not feasible. We examined the feasibility of tagging the endangered Rio Grande Silvery Minnow Hybognathus amarus with VIA tags. We evaluated four key aspects related to VIA tagging in Rio Grande Silvery Minnow: 1) fish survival, 2) fish growth, 3) tag retention, and 4) tag legibility. Fish were randomly selected to be VIA tagged and were held in laboratory aquaria for 49 days. Visible implant alphanumeric tagged fish survival was high (96.7%), tag retention was low (36.2%), fish growth was not affected by tagging, and most retained tags were clearly legible (71.4%). Because of low tag retention and application difficulty, VIA tagging may not be applicable to large-scale field studies of small-bodied fishes.
Film-Induced Tourism and Promotion of Tourist Destinations

Published: January 2025

The film tourism business incorporates a series of activities. The development of destination marketing campaigns to promote films, while, increasingly, common initiatives between DMOs and filmmakers to promote films and tourist destinations. In several situations, a film or a documentary can prove to be a crucial element of communica-tion and dissemination of a country, a city or a territory. These cinematographic imag-es can influence consumers' decisions regarding their motivations to visit the places where the films were recorded. Tourism and cinema may represent a common element in favour of regional development and community feeling (e.g. a film about the histo-ry or culture of a population). The present study, in an exploratory approach, intends to understand the phenomenon and the importance of film tourism as a preponderant element in the management of territories (i.e. tourist destinations). Therefore, semi-structured interviews were carried out to define the object of study. Future studies, through a quantitative approach, should allow a greater generalization of results.
