Dwarf galaxies are found to have lost most of their metals via feedback processes; however, there still lacks consistent assessment on the retention rate of metals in their circumgalactic medium (CGM). Here we investigate the metal content in the CGM of 45 isolated dwarf galaxies with M
* = 106.5–9.5
M
⊙ (M
200m = 1010.0–11.5
M
⊙) using the Hubble Space Telescope/Cosmic Origins Spectrograph. While H i (Lyα) is ubiquitously detected (89%) within the CGM, we find low detection rates (≈5%–22%) in C ii, C iv, Si ii, Si iii, and Si iv, largely consistent with literature values. Assuming these ions form in the cool (T ≈ 104 K) CGM with photoionization equilibrium, the observed H i and metal column density profiles can be best explained by an empirical model with low gas density and high volume filling factor. For a typical galaxy with M
200m = 1010.9
M
⊙ (median of the sample), our model predicts a cool gas mass of M
CGM,cool ∼ 108.4
M
⊙, corresponding to ∼2% of the galaxy’s baryonic budget. Assuming a metallicity of 0.3 Z
⊙, we estimate that the dwarf galaxy’s cool CGM likely harbors ∼10% of the metals ever produced, with the rest either in more ionized states in the CGM or transported to the intergalactic medium. We further examine the EAGLE simulation and show that H i and low ions may arise from a dense cool medium, while C iv arises from a diffuse warmer medium. Our work provides the community with a uniform data set on dwarf galaxies’ CGM that combines our recent observations, additional archival data and literature compilation, which can be used to test various theoretical models of dwarf galaxies.
When and How Ram Pressure Stripping in Low-mass Satellite Galaxies Enhances Star Formation
Authors: Zhu Jingyao , Tonnesen Stephanie , Bryan Greg L.
Published: December 2023

We investigate how a satellite's star formation rate (SFR) and surviving gas respond to ram pressure stripping (RPS) in various environments. Using a suite of high-resolution wind tunnel simulations with radiative cooling, star formation, and supernovae feedback, we model the first infall orbit of a low-mass disk galaxy (M
* = 109.7
M
⊙) in different host halos, ranging from Milky Way–like to cluster hosts. When the ram pressure is moderate, we find that the stripping satellite shows an enhanced SFR relative to the isolated control case, despite gas loss due to stripping. The SFR enhancement is caused, not directly by compression, but by ram-pressure-driven mass flows, which can increase the dense gas fraction in the central disk regions. The spatially resolved star formation main sequence and Kennicutt–Schmidt relations in our simulations are consistent with recent findings of the VERTICO and GASP surveys. Our results predict the environmental signals of RPS in future multiwavelength, high-angular resolution observations: the star formation and gas surface densities will be centralized, and symmetrically enhanced within the stripping radius.

We present a catalog of 315 protostellar outflow candidates detected in SiO J = 5 − 4 in the ALMA-IMF Large Program, observed with ∼2000 au spatial resolution, 0.339 km s−1 velocity resolution, and 2–12 mJy beam−1 (0.18–0.8 K) sensitivity. We find median outflow masses, momenta, and kinetic energies of ∼0.3 M

We find correlations between field-aggregated SiO outflow properties and total mass in cores (∼3σ–5σ), and no correlations above 3σ with clump mass, clump luminosity, or clump luminosity-to-mass ratio. We perform a linear regression analysis and find that the correlation between field-aggregated outflow mass and total clump mass—which has been previously described in the literature—may actually be mediated by the relationship between outflow mass and total mass in cores. We also find that the most massive SiO outflow in each field is typically responsible for only 15%–30% of the total outflow mass (60% upper limit). Our data agree well with the established mechanical force−bolometric luminosity relationship in the literature, and our data extend this relationship up to L ≥ 106

Properties of Steady Sub-Alfvénic Solar Wind in Comparison with Super-Alfvénic Wind from Parker Solar Probe Measurements
Authors: Jiao Yiming , Liu Ying D. , Ran Hao , Cheng Wenshuai
Published: December 2023

We identify more than 10 steady sub-Alfvénic solar wind intervals from the measurements of the Parker Solar Probe (PSP) from encounter 8 to encounter 14. An analysis of these sub-Alfvénic intervals reveals similar properties and similar origins. In situ measurements show that these intervals feature a decreased radial Alfvén Mach number resulting from a reduced density and a relatively low velocity, and that switchbacks are suppressed in these intervals. Magnetic source tracing indicates that these sub-Alfvénic streams generally originate from the boundaries inside coronal holes or narrow/small regions of open magnetic fields. Such properties and origins suggest that these streams are mostly low Mach-number boundary layers (LMBLs), which is a special component of the pristine solar wind proposed by Liu et al. We find that the LMBL wind, the fast wind from deep inside coronal holes, and the slow streamer wind constitute three typical components of the young solar wind near the Sun. In these sub-Alfvénic intervals, the Alfvén radius varies between 15 and 25 solar radii, in contrast with a typical 12 radii for the Alfvén radius of the super-Alfvénic wind. These results give a self-consistent picture interpreting the PSP measurements in the vicinity of the Sun.

Outflows in an active galactic nucleus (AGN) are considered to play a key role in the evolution of the host galaxy through transfer of a large amount of energy. A narrow-line region (NLR) in the AGN is composed of ionized gas extending from parsec to kiloparsec scales. It has been suggested that shocks are required to ionize the NLR gas. If AGN outflows generate these shocks, they will sweep through the NLR, and the outflow energy will be transferred into a galaxy-scale region. In order to study the contribution of the AGN outflow to the NLR-scale shock, we measure the [Fe ii]λ12570/[P ii]λ11886 line ratio, which is a good tracer of shocks, using near-infrared spectroscopic observations with the Warm INfrared Echelle spectrograph to Realize Extreme Dispersion and sensitivity (WINERED) mounted on the New Technology Telescope. In 13 Seyfert galaxies we observed, the [Fe ii] and [P ii] lines were detected in 12 and 6 targets, respectively. The [Fe ii]/[P ii] ratios in 4 targets were found to be higher than 10, which implies the existence of shocks. We also found that the shock is likely to exist where an ionized outflow, i.e., a blue wing in [S iii]λ9533, is present. Our result implies that the ionized outflow present in an NLR-scale region sweeps through the interstellar medium and generates a shock.

Xicotli data is the short name given to the dataset generated within the project framework "Integration of Biodiversity Data for the Management and Conservation of Wild Bee-Plant Interactions in Mexico (2021-2023)", as xicotli is the generic word for a bee in Nahuatl. The team comprised eco-informaticians, ecologists and taxonomists of both native bees and flora. The generated dataset contains so far 4,532 curated records of the plants, which are potential hosts of species of three focal families of bees native to Mexico: Apidae, Halictidae and Megachilidae and morphological and ecological data of the plant-bee interactions. This dataset was integrated and mobilised from citizen observations available at naturalista.mx (iNat), which were compiled through the iNaturalist project.

The new information obtained with the Xicotli data project was:

Taxonomic information about bee species curated by taxonomists based on the information contained in iNaturalist;

Taxonomic identification of the host plants by a botanist from the photos compiled by the Xicotli Data project;

Data on the ecomorphological traits of bees and plants based on expert knowledge and literature.

Taxonomic information about bee species curated by taxonomists based on the information contained in iNaturalist;

Taxonomic identification of the host plants by a botanist from the photos compiled by the Xicotli Data project;

Data on the ecomorphological traits of bees and plants based on expert knowledge and literature.

All the data were integrated into the Xicotli Data Project via the creation of new “observation fields". The visibility of the information originally contained in iNaturalist was maximized and can be consulted directly on the iNaturalist platform.
An updated Atlas of Helophorus chromosomes
Authors: Angus Robert B.
Published: December 2023

An account is given of my development of techniques to obtain well-spread Giemsa-stained banded chromosome preparations. Apparent G-banding could be obtained following very slight trypsin treatment of freshly prepared slides, but this banding was very fine (close-grained) and possibly not a reflection of chromosome structure. However, treatment of developing embryos in vitro with 5-fluorouridine produced a similar chromomere banding, which is therefore regarded as genuine. Steady accumulation of Helophorus Fabricius, 1775 karyotypes has resulted in the production of an Atlas covering 62 of the 170 species known to occur in the Palaearctic. Chromosome polymorphisms involving pericentric inversions and addition of extra C-banding regions have been found, as well as small B-chromosomes in a few species. In general, karyotypes have proved very useful in establishing the limits of individual species. Parthenogenesis involving triploidy has been found in two species. Karyotypes of experimentally produced hybrids have revealed irregularities in chromosome condensation.

Silicon-carbon films are of great interest as diamond-like materials combining unique properties, e.g. high hardness, adhesion to a wide range of materials, abrasion resistance, chemical resistance, low friction coefficient and biocompatibility. The presence of silicon in the films significantly reduces their inner mechanical stress as compared to diamond films. Currently, the films are used in industry, primarily, as solid lubricants and protective coatings. There are a large number of silicon-carbon film synthesis methods the most widely used of which are various options of chemical vapor deposition. A new silicon-carbon film synthesis technique has been suggested and tested. The technique is based on the use of high-frequency induction for obtaining plasma of silicon and carbon vapors supplied to the reaction chamber from an external source. Impurity-free silicon-carbon films containing 63–65 % carbon atoms with sp3 orbital hybridization have been synthesized on Sitall substrates. The composition, surface roughness and friction coefficient of the impurity-free silicon-carbon films synthesized using the suggested technology have been studied. The possibility of implementing resistive switching in thin silicon-carbon films in cross-bar structures with metallic electrodes has been analyzed.

A conspectus of Australian Apotropina (Diptera, Chloropidae) with the description of two new species
Authors: Ang Yuchen , Lumbers James , Riccardi Paula R.
Published: December 2023

The genus Apotropina (Diptera, Chloropidae) has a global distribution with more than 80 valid described species, of which 22 are known to occur in Australia. The Australian Apotropina fauna is poorly studied, with many species known from single type specimens, more with the morphology of the other sex unknown, and there have been no new species descriptions since 1959. Here, we describe two new species from Australia, A. maculigena Riccardi, sp. nov. and A. popeye Ang, sp. nov., and provide an updated illustrated key. We also provide a conspectus of the known Australian Apotropina with images of types and collate all original descriptions and subsequent taxonomic notes of relevance as supplementary information. Finally, we discuss the validity of two known syntype specimens of A. bispinosa due to incongruencies with the species description.

Published: December 2023

The present study is an update to the first catalogue of Russian bees published in 2017. For the Russian fauna, five recently described species are reported, as well as 45 species newly recorded since the first catalogue (including one invasive species), nine species overlooked in this previous Russian checklist, and 17 published synonymies. Original records are provided for nine species previously unknown to Russia and, as a taxonomic act, one species, Anthidium ovasi Warncke, 1980, syn. nov., is synonymised with Icteranthidium floripetum (Eversmann, 1852). Additionally, 14 species are excluded from the original catalogue and numerous other taxonomic changes and clarifications are included. The present work revises the total number of genera for Russia to 64 and the total number of species to 1,268.

La fonction d’ aesh est constituée historiquement en tant qu’« auxiliaire » de vie scolaire, dans une logique de compensation révélatrice d’une pensée intégrative – et non inclusive – de la scolarisation des élèves en situation de handicap : à eux de rentrer dans le profil « classique » de l’élève, grâce aux adaptations et à l’aide humaine apportée. Une telle conception limite la transformation vers une école véritablement inclusive. L’article questionne l’accompagnement apporté par les aesh et les attendus que l’on a à leur égard.

Stimuler la motricité sur le Crawliskate
Authors: Barbu-Roth Marianne , Soyez-Papiernik Evelyne , Dumuids-Vernet Marie-Victorine
Published: December 2023

Dans cet article nous présentons les démarches et les tests que nous avons mis en place en amont, pour évaluer les risques d’utiliser un nouveau protocole pour stimuler la motricité de grands prématurés en les entraînant à la marche quadrupède sur un mini skate dès leur sortie de néonatologie. Méthode : cette étude a été effectuée sur une population pilote de 44 grands prématurés qui ne présentaient pas de lésion cérébrale majeure mais qui étaient néanmoins à risque de développer des anomalies du développement moteur. Les sujets ont été séparés en trois groupes : un groupe Crawli entraîné sur un mini skate, le Crawliskate, un groupe Tapis entraîné à la position sur le ventre sur un tapis et un groupe Contrôle sans entraînement. Les entraînements ont été effectués 5 minutes par jour pendant 8 semaines consécutives à domicile par des professionnels. Les effets délétères éventuels de l’entraînement Crawli ont été surveillés lors de l’entraînement et en suivant les sujets jusqu’à 12 mois d’âge corrigé avec l’échelle de l’ATNAT (évaluation neurodéveloppementale d’Amiel-Tison). Résultats : les rapports relevés lors des entraînements par les professionnels ont montré une bonne tolérance des enfants et de leurs parents. Tous les nourrissons prématurés du groupe Crawli étaient capables de se propulser avec des mouvements quadrupèdes avec l’aide du Crawliskate sans effets délétères ensuite au cours de leur première année de vie. En revanche, les nourrissons positionnés directement sur le tapis sans le Crawliskate étaient incapables de se déplacer et ont développé une hyperextension transitoire du tonus passif de l’axe à 2 mois corrigés. L’entraînement Crawli semble donc plus adapté pour commencer, dès leur sortie du service de néonatologie, une intervention stimulant le développement moteur/locomoteur de grands prématurés dans une fenêtre temporelle maximale de la plasticité de leurs structures neuro motrices.
Des communs positifs aux communs négatifs
Authors: Maurel Lionel
Published: December 2023

La notion de Communs s’est dans une grande mesure diffusée dans la littérature académique en France à partir des travaux de l’économiste Elinor Ostrom autour des Commons Pool Resources . Dans cette conception, les Communs sont toujours des éléments intrinsèquement marqués positivement, en tant qu’ils constituent des biens pourvus d’utilités venant satisfaire des besoins humains (réserves en eau, bois, ressources halieutiques, etc.). Cette vision a permis un temps une meilleure prise en compte des questions écologiques dans le champ de l’économie, en mettant en lumière des pratiques de gestion partagée pouvant contribuer, dans certaines conditions, à la durabilité des ressources. Mais elle est aussi fortement marquée par une perspective « environnementaliste » et « développementiste » peu adaptée à la situation ouverte par l’Anthropocène et les défis qui la caractérisent. Dans un monde marqué par l’urgence climatique, il importe sans doute de rompre avec l’approche « bucolique » des communs positifs pour envisager en tant que Communs négatifs non plus les choses suscitant un désir d’appropriation, mais celles que plus personne au contraire ne souhaite posséder (déchets, ruines industrielles). Penser les Communs au-delà de la ressource et de l’usage permet aussi de penser comme Communs négatifs des éléments dont l’abandon ou la limitation devient critique (énergies fossiles, plastique, viande, trafic aérien, etc.).
Les communs négatifs entre féralité et remantèlement
Authors: Citton Yves
Published: December 2023

Les communs négatifs nourrissent nos vies en même temps qu’ils pourrissent nos milieux de vie. L’écologie du démantèlement pose la question de savoir comment, sans nous effondrer, couper la branche sur laquelle nos sociétés ont assis leur prospérité fragile, inégale et suicidaire. Ce bref article propose de faire résonner les communs négatifs avec deux notions mitoyennes, en espérant contribuer ainsi à la réflexion collective qui les prend pour objets – celle de féralité , telle que la définit le Feral Atlas , et celle de remantèlement , telle que l’élaborent certaines théories psychanalytiques.
Désaffecter les communs négatifs

Cet article en forme de dialogue, clin d’œil à Bruno Latour, interroge le travail éducatif appelé par l’Anthropocène. La connaissance de la contradiction entre les conditions d’habitabilité de la planète et certains de nos attachements ne peut suffire à porter la redirection écologique. Renoncer aux activités nuisibles à la planète implique dans le même mouvement d’en aimer de nouvelles, compatibles avec la biosphère, tout en étant sources de contentement durable, d’accomplissement et de créativité pour tout un chacun. Si l’enfance est une période déterminante pour la formation des « goûts et des couleurs », alors il importerait d’enquêter dès l’école primaire sur ces activités du « bon infini » et les manières de les cultiver et partager.
Lyme et le déni de certitude

Zoonose la plus importante en Europe, mais aussi première épidémie de l’Anthropocène, la maladie de Lyme aux symptômes persistants – ou Lyme long, ne fait encore l’objet d’aucune reconnaissance médicale en France. Les outils diagnostiques, les thérapeutiques, les recherches, font défaut. Observer les espaces sociaux en ligne où les malades, aux symptômes aussi bien légers que gravissimes, partagent leurs prises, questions et bouts d’enquêtes, renseigne sur les effets collatéraux du commun négatif que constitue, au-delà de la pandémie elle-même, le déni de certitude qui l’affecte. Si le coût financier, pour la collectivité, de cette errance médicale et de ses conséquences en termes d’arrêts de travail, d’invalidité et autres, est estimé à plus de 12 milliards d’euros par an, on documente ici ce que signifie, en termes d’empowerment forcé, l’enquête indéfinie nécessaire pour survivre ou aller mieux, et son style plus guerrier que diplomatique de rapport aux pathogènes microbiens.
Soigner les communs négatifs en temps de pandémie
Authors: Monnin Alexandre
Published: December 2023

Cet article revient sur la pandémie de Covid et, s’inspirant de textes et concepts inscrits dans la mouvance de l’auto-défense sanitaire, défend l’assimilation de la perspective des communs négatifs avec un communisme du désastre ou du soin. La pandémie interroge selon nous l’exposition des travailleur-euses à un risque léthal du fait de la contrainte de subsister en travaillant pour des organisations. À l’instar du propos d’Yves Citton dans ce même numéro, cet état de fait invite à imaginer d’autres modèles de protection sociales adaptés à une économie du soin des communs négatif. Revenant sur la pandémie, à partir du concept de « diagonalisme » proposé par William Callison et Quinn Slobodian, il apparaît que c’est le défaut d’une telle économie qui contribua à pousser des foules de free-lances à se radicaliser sur YouTube ou Twitter, sur un mode conspiritualistes, alors que les cadres pouvaient télétravailler via Zoom ou Teams. Une économie de l’incurie s’est ainsi substitué à une économie du soin.
L’Europe ou rien
Authors: Caminiti Lanfranco , Galmozzi Chicco , Mantelli Brunello
Published: December 2023

L’invasion de l’Ukraine est la tentative de la Russie de fermer militairement sous un talon de fer le processus politique qui a commencé avec la chute du mur de Berlin et le rapprochement progressif de l’Est vers l’Ouest, après la longue « césure » de la seconde moitié du XX e  siècle. Le destin de l’Europe se joue donc en Ukraine. Il n’est donc ni fortuit ni étrange que ceux qui n’ont jamais cru à un processus de construction et de refondation de l’Europe aient pris parti, tant à droite que dans la gauche radicale contre l’Ukraine. L’Ukraine est un « prétexte », tout comme elle l’est pour Poutine – la grande cible, c’est l’Europe. La question politique posée par la guerre en Ukraine est celle de l’Europe. Une Europe qui est aujourd’hui faible, fragile, indécise. Seule la montée en puissance de nouveaux mouvements de justice sociale peut prendre en charge la construction d’un espace européen. Tel est le « défi politique » que pose la guerre en Ukraine – la « troisième voie » entre la guerre et la paix. Transformer la guerre en acte fondateur de la Fédération européenne.

Au-delà de cette compréhension juridico-institutionnaliste, cet article propose trois stratégies nationales qui, en cas d’interdépendance asymétrique et de faibles incitations à des mesures communes, conduisent à la désintégration européenne : l’action unilatérale, la coopération bilatérale avec des pays tiers et le recours excessif à des acteurs tiers. L’analyse empirique de la désintégration lors de la crise pétrolière de 1973 et de la crise migratoire de 2015 a également des implications plus larges pour les crises les plus récentes de l’Union européenne.
Humaines fractures, cercles soignants, cercles de formation
Authors: Vannotti Marco , Gennart Michèle
Published: December 2023

Dans cette section, qui fait suite à l’article « Le phénomène pathique et la rencontre thérapeutique » publié dans le même numéro, nous aborderons la question de savoir comment développer une formation à la psychothérapie qui tienne rigoureusement compte de l’implication du soignant dans le champ même où s’exercent son savoir et son savoir-faire. L’apprentissage de la psychothérapie aurait pour fondement un savoir- être  : une initiation vivante et pensante à la condition humaine et à sa nature pathique fondamentale. Dans son cheminement, l’étudiant doit pouvoir compter sur l’expérience de formateurs engagés qui le soutiennent et le guident, et sur une solidarité active du groupe de condisciples, pour faire face au déconcertant, au périlleux, mais aussi au transformateur de l’expérience pathique.
Spectral solutions for the time-fractional heat differential equation through a novel unified sequence of Chebyshev polynomials
Authors: Abd-Elhameed Waleed Mohamed , Ahmed Hany Mostafa
Published: December 2023

In this article, we propose two numerical schemes for solving the time-fractional heat equation (TFHE). The proposed methods are based on applying the collocation and tau spectral methods. We introduce and employ a new set of basis functions: The unified Chebyshev polynomials (UCPs) of the first and second kinds. We establish some new theoretical results regarding the new UCPs. We employ these results to derive the proposed algorithms and analyze the convergence of the proposed double expansion. Furthermore, we compute specific integer and fractional derivatives of the UCPs in terms of their original UCPs. The derivation of these derivatives will be the fundamental key to deriving the proposed algorithms. We present some examples to verify the efficiency and applicability of the proposed algorithms.
Exploring the complexity of natural languages: A fuzzy evaluative perspective on Greenberg universals
Authors: Brosa-Rodríguez Antoni , Dolores Jiménez-López M. , Torrens-Urrutia Adrià
Published: December 2023

In this paper, we introduced a fuzzy model for calculating complexity based on universality, aiming to measure the complexity of natural languages in terms of the degree of universality exhibited in their rules. We validated the model by conducting experiments on a corpus of 143 languages obtained from Universal Dependencies 2.11. To formalize the linguistic universals proposed by Greenberg, we employed the Grew tool to convert them into a formal rule representation. This formalization enables the verification of universals within the corpus. By analyzing the corpus, we extracted the occurrences of each universal in different languages. The obtained results were used to define a fuzzy model that quantifies the degree of universality and complexity of both the Greenberg universals and the languages themselves, employing the mathematical theory of evaluative expressions from fuzzy natural logic (FNL). Our analysis revealed an inversely proportional relationship between the degree of universality and the level of complexity observed in the languages. The implications of our findings extended to various applications in the theoretical analysis and computational treatment of languages. In addition, the proposed model offered insights into the nature of language complexity, providing a valuable framework for further research and exploration.

Werner Syndrome is a rare autosomal recessive condition characterized by premature aging and increased risk of malignancies due to gene mutations associated with DNA stability. We present the first case report of a 29-year-old Hispanic female with WS diagnosed with breast cancer. Diagnostic mammography and ultrasound, breast MRI and PET examinations revealed two lesions biopsy proven as invasive ductal carcinoma. The patient underwent neoadjuvant chemotherapy and radical mastectomy. Recurrence occurred 10 months postoperatively with molecular analysis demonstrating TP53 mutations. The multifactorial assessment of breast cancer in this case study is crucial towards optimizing screening, diagnosis and management of this disease in patients with WS.
Translingual and Transcultural Engagement
Authors: Gruber Sibylle , Barrón Nancy G.
Published: December 2023

This chapter uses an epistemological framework rooted in feminism, post-colonialism, and deconstruction to situate discussions of how knowledge is created, and how collaborative knowledge creation extends our understanding of the shifting and inter-connected cultural, social, and language realities that we experience in our lives. The authors show that these collaborative efforts construct meaning, expand meaning, and change previously accepted meaning. They show how they interrogate the normalization of this discipline, how they address the need for continuously re-examining and re-thinking approaches to translingual and transcultural collaboration as a way to construct new meaning, and how collaborative work continues to address and redefine the norms and realities of the dominant academic culture so that our contributions can lead to much-needed change in how we understand our roles as participants and stakeholders in translingual and transcultural collaborations.
Digital Technology and Language Learning
Authors: Tomita Yasuyo
Published: December 2023

The advancement of digital technologies allows us to communicate in plurilingual contexts without learning additional languages. This makes the author wonder what learning languages means in today's technologically advanced environment. Therefore, this chapter explores the meaning of learning languages and taking language courses from multiple theoretical perspectives, including ecology, digital nature, agency and emotions in the action-oriented approach, and instructed second language acquisition. Using the concept of digital nature, the chapter argues that technology has provided us with freedom from the pressure to memorize and process a great deal of information owing to “our” externally existing knowledge (i.e., the internet) and magical tools such as real-time translation apps. The chapter discusses how this freedom allows us to exert our agencies, utilize noise for creativity and innovation, and take risks to learn languages through the fine-tuned delicate art of work, or teaching, valued in digital nature.
Bilingualism in Cuba
Authors: Borjian Ali
Published: December 2023

This chapter considers the impact of English in a context where it is not a predominant language. For decades, the post-revolutionary Cuban government has recognized the importance of English in the economic advancement of the country. Although other world languages, especially Russian, have been promoted in Cuba, English has remained the most popular second language for the Cuban population. How Cuban teachers of English became interested in learning English and factors that contributed to their high level of proficiency in English is examined, and the social and economic impact of this language in their lives is investigated. Obstacles teachers face and their recommendations for ways to enhance English language development in Cuba are presented. Factors that keep them in the teaching profession or could force them to leave are also revealed.
Migration and Language Dynamics
Authors: Danso-Wiredu Esther Yeboah , Eshun Emma Sarah
Published: December 2023

Many different cultural traits are assimilated through migration; one such trait is language. In the processes of migration, many languages are moved from their ecological domain to new ecologies. About 60 known languages are spoken in the country of Ghana, and language experts argue that at the initial stages of migration, migrants might keep their indigenous languages. However, with time, the intents of maintaining the original language become wobbly. This study examines language dynamics in migration at University of Education, a multilinguistic community with diverse migrants. This case study uses a mixed methods approach. Findings indicate evidence of code-switching, code-mixing, dilution of original language, language shift, and total loss of original language and development of a new language. Negotiation of language use among migrants is paramount in or during migration so that existing indigenous languages will be saved from extinction as well as to maintain their vitality and the identity of the people who owns it.
Construction of Dialogue
Authors: Davis Lavon
Published: December 2023

The ways dialogue is constructed is influenced by a myriad of factors—institution, context, the multiple identities people hold. Based on these factors, people bring with them varied experiences that inform the way they communicate with one another, both consciously and subconsciously. This chapter takes an in-depth look at how dialogue is constructed in the higher education setting. Utilizing a discourse analysis lens, the author conducted a 45-minute-long interview to obtain information about the experience of one Black male professional in higher education. During this interview, the author sought to investigate his usage of multiple varieties of English that showcased how a professional in higher education employed racial linguistic practices as a bridge between faculty/staff norms and student dynamics and interactions. Through this process, the author takes a look at how language shifts and switches play a role to develop the legitimacy, connection, and sharing that takes place in a higher education environment for students and staff.

This chapter will discuss what disabilities are, how they can impact students in an online classroom, and what it means to be ADA compliant. In addition, this chapter will provide some examples of practical applications for designing ADA compliant online classrooms with the purpose of creating relationships. Higher education faculty are at the frontline, making online classrooms accessible and setting the tone for the learning environment. They can engage in relationships with all students and work actively to come alongside those who may need additional support in the classroom. It is in creating relationships with students that barriers are broken and more opportunities for access arise.
Leveraging Online Communities for Building Social Capital in University Libraries
Authors: Ni Yuanjun , Lam Apple Hiu Ching , Chiu Dickson K. W.
Published: December 2023

This study investigates the development of social capital in university libraries using the Fudan University Medical Library (FUML) as the case. The authors first use the SWOT matrix to analyze the FUML based on librarian interviews, official websites, and previous literature. Next, they construct a social capital evaluation framework for university libraries with four dimensions (degree of user demand, level of trust, visibility, and status in users' minds). Guided by the framework, our findings indicate that FUML's user demands in recent years are optimistic, though trust, visibility, and library status vary in users' minds. Thus, they suggest some strategies to help improve patron-library relations through online communities, such as using social media, multi-online channel user feedback, and improving related employee training. This study provides insights into how university libraries can build online relations from social capital concepts. Scant studies have applied social capital to investigate the relationship between university libraries and students, especially in East Asia.

Authors: Faisal Sarika , Hossain Syed Far Abid , Rayhana Rayisa , Nawshin Shawnila
Published: December 2023

The purpose of this study is to examine whether oil price hikes are leading consumers to switch to alternative forms of cooking oil. This study presents the viewpoints of subject-matter specialists, as well as consumer choices. This study applied a qualitative research approach with literature review and person administered survey. The authors found that the rise of the price of soybean oil positively influences consumers to switch to alternative oils. Moreover, the authors also discovered that consumers are more conscious about health benefits while oil prices are hiked. Additionally, the availability of various kinds of oils in the market influences consumers to switch as per the study. Theoretically, the study contributes to the extant literature (buyer decision theory) by discovering the oil price hike, brand switching, and sustainable oil consumption through variety seeking tendency.
Immigrants Who Have Changed the Course of History
Authors: Fain Jeanne Gilliam , Lowery Ruth McKoy
Published: December 2023

A positive exposure to diverse children's literature, literature which represents a more inclusive experience of the many cultural, ethnic, racial, and socioeconomic backgrounds representative of the people of the United States of America (USA), is important in the current era of book bans and censorship of schools' curricula. Immigrants and their experiences are often overlooked in the curricula. This chapter discusses contemporary children's biographies of immigrants who have made a difference in the USA, while implementing a three-lenses framework—reader lens, evaluative lens, and instructional lens—to interrogate the texts. The chapter offers this approach to help classroom teachers critically read and enjoy before selecting reading materials for their students.

Published: December 2023

In the ever-evolving educational landscape, book challenges have gained prominence, prompting discussions within education about how to respond to such challenges. Educators and librarians often encounter obstacles in championing students' right to read due to a lack of resources and confidence. Young adult (YA) literature courses are a valuable avenue to equip educators and librarians in navigating book challenges. This chapter illuminates an instructional approach used in the authors' YA literature courses, demonstrating how pre-service and in-service teachers and librarians may prepare to counter instances of book challenges within their unique environments. Through collaborating with colleagues using the RAFT instructional strategy in a safe setting, the authors suggest educators and librarians will become more self-assured in standing up to book challenges.
