Authors: Núñez García Sandra Elizabeth
Published: February 2025

INTRODUCCIÓN: La leishmaniasis es un importante problema de salud pública en áreas endémicas debido a su amplia distribución y prevalencia. Actualmente existe un tratamiento con altas tasas de curación. Sin embargo, el recibir este tratamiento implica movilizaciones, gastos económicos y visitas diarias a los centros que brindan este tratamiento, lo cual ocasiona verdaderos problemas en el día a día de las personas afectadas, algunas de las cuales terminan abandonante el tratamiento. OBJETIVO: Analizar los factores socioeconómicos, culturales y relacionados con la atención en salud, así como la tasa de abandono al tratamiento y las estrategias que han sido implementadas para evitarlo. MATERIALES Y MÉTODOS: Revisión sistemática concebida a través de la estrategia PICO y realizada, utilizando la metodología PRISMA, evaluación JBI y presentación de resultados en una tabla de síntesis. RESULTADOS Y DISCUSIÓN: Entre los factores socioeconómicos y culturales del abandono del tratamiento están: estrato social bajo, altos costos farmacéuticos, creencias de curación usando medicina casera y residir en áreas distantes de los centros donde se administra el tratamiento. Las tasas de abandono varían entre 2.4% y 14.2%, llegando incluso hasta 22.4%. Entre las estrategias para aumentar la adherencia al tratamiento están la monitorización del tratamiento y reacciones adversas a través de Apps y el desarrollo de nuevos medicamentos con procesos de administración más sencillos. CONCLUSIÓN: El tratamiento de la leishmaniasis es complejo y una de las mayores barreras o factores asociados al abandono del mismo son las limitantes económicas y las creencias culturales de los poblados más afectados.

Two new genera of freshwater leeches from Europe and Africa (Hirudinea: Glossiphoniidae)
Authors: Bolotov Ivan N. , Pešić Vladimir
Published: February 2025

Based on phylogenetic and morphological evidence, we introduce two new genus-group names for freshwater leeches of the family Glossiphoniidae. First, Eurobdelloides Bolotov & Pešić gen. nov. is described for Batracobdelloides moogi Nesemann & Csányi, 1995, a rare snail-feeding leech from Europe. Second, Hippobdelloides Bolotov & Pešić gen. nov. is designated for Clepsine jaegerskioeldi Johansson, 1909, a peculiar hippopotamus-associated leech from Sub-Saharan Africa. Both taxa represent basally derived, relict phylogenetic lineages. Two new combinations are proposed as follows: Eurobdelloides moogi (Nesemann & Csányi, 1995) gen. & comb. nov. and Hippobdelloides jaegerskioeldi (Johansson, 1909) gen. & comb. nov.

Jadidism and Political Reform: Shaping the Future of Uzbekistan
Authors: Sobirovich Turdiyev Bekhruz
Published: February 2025

Jadidism, a reformist movement of the late 19th and early 20th centuries, played a pivotal role in the political and cultural awakening of Central Asia. Advocating for modern education, press, and governance reforms, the Jadids sought to reshape outdated socio-political structures. Their legacy remains relevant in “New Uzbekistan”, where their ideas align with contemporary efforts to foster national identity, democratic governance, and the “Third Renaissance”. Despite political persecution under Russian and Soviet rule, their intellectual contributions continue to inspire reforms in education, civic responsibility, and ideological renewal, reinforcing the importance of enlightenment in nation-building and political transformation.

Authors: Adamić Ciglar Viktorija
Published: February 2025

Managing legal risks is becoming an increasingly significant part of corporate governance, especially in the context of increasingly complex legislative frameworks and growing compliance requirements. The ISO 31022:2022 standard provides guidelines for effective legal risk management, complementing the broader frameworks of ISO 31000:2014 and ISO 31010:2019. This article explores the principles, processes, and tools for managing legal risks and emphasizes the importance of integrating them into overall business strategies.Legal risks, defined as the possibility of negative consequences arising from legal issues, include contractual risks, compliance risks, regulatory risks, and intellectual property. Managing these risks requires an effectively structured approach. The use of tools such as analytics, simulations, and legal databases enables better decision-making and the mitigation of potential damages.The article also highlights the role of education and communication in building an organizational culture focused on legal risk management. It is important to note that implementing legal risk management contributes to business stability, strengthens stakeholder trust, and enables organizations to be more resilient to legal challenges.
Efficiency of mono-silicic coated urea with various fertilizing techniques on maize (Zea mays L.) performance and nitrogen content
Authors: Babar Saima Kalsoom , Abbasi Zeeshan , Rajper Inayatullah , Babar Hafizullah , Shujrah Hassan Ali
Published: February 2025

Environmental deterioration and nitrogen (N) losses are closely interrelated. In the realm of nitrogenous fertilizers, urea holds a prominent position due to its unique characteristics and high N content. While urea is valued for its ease of application, excessive use often leads to significant losses through leaching and volatilization. Coating urea with biodegradable materials offers a potential solution by enabling the steady release of N. In recent years, nanotechnology has been employed in various ways to coat urea, improving its efficiency. With the dimensions of nano-fertilizers and N losses in mind, a field experiment was conducted at the Soil Fertility Research Institute (SFRI) in Tandojam, Pakistan. The study investigated the effects of nano-silicon (nSi)-coated urea on the growth, N uptake, and nitrogen use efficiency (NUE) of maize plants. Nano-Si was used as a urease inhibitor with urea (160 kg N ha⁻¹) and combined with different coating materials, namely vegetable oil and palm stearin, to assess binding reliability. Two fertilization application techniques broadcasting and placement were also evaluated. The highest agronomic performance was observed when nSi-coated urea with palm stearin was applied, while coating with vegetable oil was less effective but still outperformed broadcast urea. NUE and N uptake were significantly improved when nSi and urea were combined, compared to other treatments. Additionally, plants demonstrated the ability to utilize nano-Si, a sustainable byproduct derived from rice husks. The overall findings of this study are promising and provide valuable insights for future strategies to enhance nitrogen use efficiency while mitigating environmental degradation.
POESÍA DIGITAL LATINOAMERICANA: INTELIGENCIA POÉTICA IMPRESA, DIGITAL (ELECTRÓNICA, CIBERNÉTICA) Y ARTIFICIAL
Authors: CORREA-DÍAZ LUIS , WEINTRAUB SCOTT
Published: February 2025

América Latina, a partir y durante la segunda mitad del siglo XX, no ha estado ajena al impacto de las nuevas tecnologías en los ámbitos de las artes y, en especial, la literatura, aunque ésta sea y siga renuente, por una suerte de profesión de fe mal entendida, a los cambios radicales, transformadores, que vengan de otras áreas que no sean los que pide la política y la sociología. Este artículo sobre las poéticas digitales latinoamericanas busca tomar el pulso a las formas poéticas emergentes cuya historia está más entrelazada con lo computacional de lo que a menudo se ha reconocido. Como sostiene el crítico Loss Pequeño Glazier, “la poesía es un campo de escritura/programación cuya alianza con las prácticas digitales parece ser generalmente no reconocida. No ver la conexión entre las prácticas poéticas y las nuevas tecnologías parece subestimar un género literario que ha visto su práctica innovadora consistentemente a la vanguardia de las investigaciones artísticas del siglo XX” (153). Con este vínculo entre la forma experimental y las prácticas culturales en mente, nuestro estudio investiga la intersección entre lo literario, lo cultural y lo tecnológico para reflexionar sobre las formas en que la tecnología digital ha reformado y reconfigurado radicalmente casi todos los aspectos de la cultura contemporánea. Partiendo por referencias a importantes precursores de la poética digital contemporánea (desde las textualidades protohipertextuales de Jorge Luis Borges y protocibernéticas Carlos Gemán Belli) hasta los primeros experimentos con tarjetas perforadas de Omar Gancedo y códigos QR de Fabio Doctorovich (con énfasis aquí en la “poesía computable”), poetas concretos (como Augusto de Campos) y la poesía cinética de Ana María Uribe, nuestro artículo pasa a la aparición de proyectos poéticos digitales basados en la web a partir de 1995 (Gustavo Romano, Eduardo Kac, Belén Gache, Luis Bravo, Santiago Ortiz, Karen Villeda, entro otros/as) hasta llegar al impacto indeleble del advenimiento de la Inteligencia Artificial y su poder transformador de la conciencia y el quehacer humano en todos los ámbitos, donde lo digital ya es un episodio de una historia que ahora le pide al poeta entrenar su voz junto a la de la máquina en un diálogo que hoy llamamos ‘machine learning’, aquí estudiamos poetas tales como Silvia Veloso, Eugenio Tisselli, Martín Rangel y Roger Rivero, entre los más destacados.
DISCULPEN LA AUDACIA: MEMORIAL E IRREVERENCIAS DE LA POESÍA ESPECULAR
Authors: GALÁN JULIO CÉSAR
Published: February 2025

Este artículo analiza la aparición de una propuesta poética reciente: la poesía especular. Para ello queremos determinar, en primer lugar, sus antecedentes iberoamericanos, sobre todo, los referentes a Latinoamérica (algunas tendencias vanguardistas y referentes como Vicente Huidobro, neovanguardias como el concretismo, alguno de los representantes del neobarroco y autores consagrados como Leónidas Lamborghini o Héctor Viel Temperley) y las relaciones con los mismos. Posteriormente pasaremos a una posible definición de la poesía especular como corriente lírica y no como escuela, concepto histórico o movimiento, además de una potencial categorización con sus influencias mutuas y sus fusiones; y una retórica utilizada por parte de los poetas especulares. Entre las conclusiones más destacadas concretamos la culminación de una manera de sentir y de pensar la poesía, desde un modo de trasladar y conectar forma de vida y forma de creación.
I-band Asymptotic Giant Branch Stars. I. Exploring a New Standard Candle for the Extragalactic Distance Scale*
Authors: Madore Barry F. , Freedman Wendy L. , Hoyt Taylor , Jang In Sung , Lee Abigail J. , Owens Kayla A.
Published: February 2025

In the I-band color–magnitude diagrams of resolved nearby galaxies, the reddest asymptotic giant branch (AGB) stars form a previously unremarked-upon, but nevertheless distinct and easily identified population of high-luminosity stars. Hereafter we refer to this population as being comprised of I-band AGB (IAGB) stars. Identifying these stars in the Large Magellanic Cloud (LMC), the Small Magellanic Cloud (SMC) and in NGC 4258 (for all three of which there are published geometric distances) we find that the marginalized luminosity functions are each well approximated by single-peaked Gaussians, having 1σ dispersions of  ±0.22 mag,  ±0.25 mag and  ±0.24 mag, respectively. The zero points for the modal I-band absolute magnitudes of IAGB stars are found to be M

I
 = −4.49 ± 0.003 mag (stat) in the LMC (4204 stars), M

I
 = −4.67 ± 0.008 mag (stat), for the SMC sample (916 stars), and M

I
 = −4.78 ± 0.030 mag (stat) for NGC 4258 (62 stars). A global average over these three independent calibrations of the IAGB zero-point (weighted inversely by squares of their systematic errors) gives  〈M

I
〉 = −4.65 ± 0.119 mag (stat)  ±  0.025 (sys). In Paper II we will show the results of applying the IAGB Method to 92 galaxies additional galaxies resolved by Hubble Space Telescope, reaching out to distances just short of 10 Mpc.
ALMA Observations of Peculiar Embedded Icy Objects
Authors: Shimonishi Takashi , Onaka Takashi , Sakon Itsuki
Published: February 2025

We report the results of molecular line observations with the Atacama Large Millimeter/submillimeter Array (ALMA) toward two peculiar icy objects, which were discovered serendipitously by infrared spectroscopic survey of the Galactic plane with the AKARI satellite. Previous infrared observations have reported that both objects show deep ice and dust absorption features that are often seen in embedded young stellar objects (YSOs) or background stars sitting behind dense clouds; however, they are located neither in known star-forming regions nor in known dense clouds. Their infrared spectral energy distributions (SEDs) show peaks around 5 μm, which are incompatible with existing SED models of typical embedded YSOs. The present ALMA observations have detected compact emission of CO(3–2) and SiO(8–7) at the positions of the icy objects. The observed large column ratios of gas-phase SiO/CO (∼10−3) in both objects, as well as their broad line widths (8–14 km s−1), imply that they are associated with shocked gas. Although a large dust extinction (A

V
 ∼ 100 mag) is expected from their deep dust/ice absorption, no dust continuum emission is detected, which would suggest a large beam dilution effect due to their compact source sizes. Their systemic velocities are clearly separated from the surrounding CO clouds, suggesting that they are isolated. The characteristics of their SEDs, the presence of deep ice/dust absorption features, compact source size, and SiO-dominated broad molecular line emission cannot easily be accounted for by any of known interstellar ice-absorption sources. They may represent a previously unknown type of isolated icy objects.
Effects of Martian Dust Storms on Ionospheric Peak Altitudes
Authors: Lou Yu , Zou Hong , Ye Yu Guang , Wang Jin Song
Published: February 2025

The effects of Martian dust storms on the atmosphere and ionosphere is one of the hot topics in Mars research. This paper reports on the effects of a local dust storm on the ionospheric peak altitude based on electron density profile observations from the Mars Global Surveyor Radio Science experiment during a dust storm event in late 2004. By employing a profile fitting technique, we determined the peak altitudes of both the M1 and M2 layers. A statistical analysis of different dust storm phases was conducted in conjunction with changes in atmospheric dust opacity. The results indicate that during the phase of rapid increase in global opacity, the peak altitudes of the two layers are elevated differently. After the opacity reaches saturation, the peak altitudes start to decrease slowly, with distinct decreasing trends for each layer. This suggests that dust storms exert different effects across various altitudes within the Martian ionosphere and atmosphere, which require the introduction of new physical processes for explanation. The discussion of the relationship between opacity and peak altitude contributes to a deeper understanding of the dynamics by which dust storms influence the Martian atmosphere and ionosphere, offering new insights for dust storm observation and future forecasting efforts.

The gravitational-wave (GW) event S230518h is a potential binary neutron star–black hole merger (NSBH) event that was detected during engineering run 15, which served as the commissioning period before the LIGO–Virgo–KAGRA O4a observing run. Despite its low probability of producing detectable electromagnetic emissions, we performed extensive follow-up observations of this event using the Gravitational-wave Electromagnetic Counterpart Korean Observatories (GECKO) telescopes in the Southern Hemisphere. Our observations covered 61.7% of the 90% credible region, a 284 deg2 area accessible from the Southern Hemisphere, reaching a median limiting magnitude of R = 21.6 mag. In these images, we conducted a systematic search for an optical counterpart of this event by combining a convolutional-neural-network-based classifier and human verification. We identified 128 transient candidates, but no significant optical counterpart was found that could have caused the GW signal. Furthermore, we provide feasible kilonova properties that are consistent with the upper limits of the observations. Although no optical counterpart was found, our result demonstrates both GECKO’s efficient wide-field follow-up capabilities and usefulness for constraining properties of kilonovae from NSBH mergers at distances of ∼200 Mpc.

bands. These observations were conducted using the Comet Search Program telescope at Xingming Observatory from 2018 December 22 to 2020 February 15, and more than 5600 effective images were obtained on each filter across 79 nights. Additionally, we compiled long-term variability data spanning 34 yr in the optical UBVRI bands. Using the power-enhanced F-test and nested ANOVA test, we found intraday variability (IDV) on 31 nights and possible IDV on 20 nights in the i′ band. Similarly, IDV was detected on 35 nights in the r′ band, while possible IDV was observed on 22 nights. The minimum variability timescale is 7.33 ± 0.74 minutes, and the estimated black hole masses are (0.68 ∼ 5.12) × 108
M
⊙. The spectral variability and long-term optical light curves reveal a bluer-when-brighter trend on intraday timescales. The long-term optical flux density and spectral index exhibit periodic variability with a timescale of about 1038 days. An anticorrelation between optical flux and spectral index was observed, with a time delay of −140 days. Variability across different optical bands exhibited a strong correlation, with no discernible time lag. From the IDV, spectral variability, correlation, and time delays between different bands, we conclude that these radiation characteristics may result from the shock-in-jet model scenario.
Arctia menetriesii: Ecological, phenological, and life history traits of an iconic boreal moth based on over a century-long dataset (Lepidoptera, Erebidae, Arctiinae)

The Menetries’ Tiger Moth Arctia menetriesii can be considered a prospective umbrella/indicator/flagship species for conservation programs, highlighting primeval Eurasian taiga forests. To examine its inter-annual population dynamics, host plants, habitat preferences and phenology, a dataset from field surveys and experimental research was compiled. The species’ rarity may be, at least partly, an artifact of its low detectability in nature due to its preference for hard-to-reach areas, short flight period of the imago, and, perhaps, limited daily activity. The natural survival patterns of A. menetriesii are still unknown but in breeding experiments maximum mortality occurred at the larval stage (mean ± S.E. = 84.6 ± 6.2%; n = 7). This estimate does not take into account the potential impact of parasitoids, predators, and floods that may also decrease the total abundance of A. menetriesii. Moreover, several limiting factors may contribute to the extreme rarity of this species: climate influence, dependence on toxic host plants, fungal disease and desiccation in overwintering larvae. Our research indicates that there are clear differences between European and Asian populations of the species. In Europe, it occurs more rarely, in odd years, and with restricted latitudinal, elevational, and habitat ranges, perhaps due to the founder effect. Our findings reveal that long-term series of A. menetriesii annual captures do not align with the global trend of insect declines. Further research is necessary to create a climatic niche model and to assess possible range shifts under past and future climate scenarios.
On art, science, and the conservation of subterranean ecosystems

Published: February 2025

Caves, with their unique geologic and biological features, have inspired human imagination throughout history. From photography to movies, through comics, painting, and poetry, subterranean ecosystems feature prominently in various forms of artistic expression, often incorporating scientific ideas or concepts. Integrating art with science offers a powerful way to convey the uniqueness and importance of the organisms that inhabit subterranean ecosystems, emphasizing their importance as providers of key ecological and cultural services. This, in turn, would help promote their conservation. We discuss realized and unrealized connections between subterranean biologists and artists, aiming to achieve broader protection for subterranean ecosystems. We showcase the different art forms that depict subterranean environments, explain how each aligns with conservation science, and highlight the mutual benefits artists and researchers in subterranean biology can derive from collaboration. In doing so, we pose two important questions: How can we effectively bridge the cultural divide between subterranean scientists and artists? And how can we assess the effectiveness of art in enhancing science communication about subterranean ecosystems and their conservation? By addressing these questions, we envision a future where art and science intersect to safeguard the rich and diverse subterranean biological and cultural heritage.

Published: February 2025

This study aims to survey mammal diversity on Ko Pha-ngan, located 80 km off the east peninsular coast of Surat Thani province, Thailand. Thirteen camera trap sites, 32 transects, six drift line fence traps, five mist net trap sites, and nine live trap sites placed in human settlement, human-disturbed forest, and national park forest from February 2021 to September 2023 were utilized. A total of 28 mammal species of eight orders, 17 families, and 21 genera were found. Among them, 11 species are flying mammals while the remaining are terrestrial. Of the species detected, Manis javanica (pangolin) is critically endangered, while Nycticebus coucang (slow loris monkey) is endange by IUCN Red List. Additionally, Rusa unicolor (sambar deer) is vulnerable and Pteropus cf. hypomelanus (island flying fox), Trachypithecus obscurus (dusky leaf monkey), and Ratufa bicolor (giant black squirrel) are near threatened. These findings highlight the need to conserve and protect both national park forest and human-disturbed forest from anthropogenic pressures due to the finite area of an island, in which potential local extinction risk is higher.

Purpose

The purpose of this 8-week interdisciplinary educational program was to provide evidence-based fall prevention information to adults aged ≥65 years residing in an assisted living community.

Method

Eight 1-hour sessions on fall education were performed by interdisciplinary experts at an assisted living community. Control and intervention groups completed four assessments at baseline and completion of the program.

Results

Both groups had decreased Timed Up and Go (TUG) and Fear of Falling scores. The intervention group had increased scores on the knowledge of falling questionnaire, whereas the control group had decreased scores, indicating the education was effective in increasing knowledge of falls. Although not statistically significant, these results are clinically significant and reveal the positive effects of the interdisciplinary program.

Conclusion

Fall prevention education was successful in increasing older adults' knowledge about fall risk factors. There were decreases in TUG and Fear of Falling scores, revealing a positive impact of the program. [

= 0.017). Non-Hispanic White children had a lower VD and VSD of the SCP in the inner superior ring (3 × 3-mm), a higher VD and VSD of the SCP and WR in the central ring (6 × 6-mm), and a lower FAZ area (6 × 6-mm) (
P
< 0.05).

Conclusions

This study presents a database for expanded field vascular metrics in pediatric subjects across various angiogram sizes. The VD increases throughout childhood and the FAZ circularity diminishes. Future studies using SS-OCTA will need to account for influencing factors such as sex, age, race, and ethnicity.

Okna brez monad
Authors: Benčin Rok
Published: February 2025

The monograph ('Monadless Windows. Aesthetics from Heidegger to Rancière') follows the development of aesthetics in key thinkers of 20th century philosophy, such as M. Heidegger, T. W. Adorno, and G. Deleuze. It argues that the central trait of this development is the encounter with an artwork in which a philosopher identifies thought. The artwork thinks and therefore it bears implications for the philosophical understanding of being and the world. But in order for philosophy to be able to grasp the thought of art it has to renounce the classical notion of representation. Art does not represent the world; it expresses being, which remains hidden in the representational constitution of the world. In the first part of the book, contemporary approaches such as A. Badiou’s ontology and J. Rancière’s aesthetics form the ground for a critical assessment of the aesthetical heritage of the 20th century and for rethinking the notion of representation beyond the alternative between imitation and expression of being. The second part explores the notion of the world in contemporary philosophy through readings of Leibniz’s multitude of possible worlds, on the one hand, and the fictional worlds of modernist literature (S. Mallarmé, M. Proust), on the other. The third and final part addresses different ways in which philosophy reads specific artworks and how it identifies their political dimension.

Des observatoires pour accompagner les réformes foncières (Madagascar, Mali)
Authors: Grislain Quentin , Lavigne Delville Philippe , Burnod Perrine
Published: February 2025

En Afrique francophone, les observatoires sont promus depuis une trentaine d’années comme instruments de production de connaissances sur les dynamiques foncières, en appui à la préparation ou la mise en œuvre de réformes. Mais seul un petit nombre a réellement été mis en place et très peu sont parvenus à exister plus que quelques années. À partir de ce paradoxe, l’article interroge la place des observatoires dans les processus de réforme foncière et les raisons du peu de soutien concret dont ils ont bénéficié. Étudiant deux cas contrastés, en préparation d’une réforme (Mali, 1994-1998) ou en appui à sa mise en œuvre (Madagascar, depuis 2007), il analyse ensuite comment ils ont été créés dans un contexte politique spécifique, grâce à l’investissement d’un réseau d’acteurs portant le projet. Il discute enfin comment ils ont, ou pas, réussi à résister à des épreuves diverses. Cet article illustre ainsi l’intérêt de lire les projets dans une approche croisant socio-anthropologie du développement et sociologie des sciences.
Neorruralidad y temporalidades alternativas. Un estudio de Los llanos, de Federico Falco, y Mamut, de Eva Baltasar
Authors: Gil María Ayete
Published: February 2025

Tanto en Los llanos (2020), de Federico Falco, como en Mamut (2022), de Eva Baltasar, la huida a un espacio radicalmente otro, aislado, alejado de la urbe cosmopolita y del imperativo aceleracionista que la rige, genera una temporalidad alternativa, acorde a ritmos distintos en estrecha relación con el medio natural. Este trabajo analiza ese tiempo alternativo y a la contra desde el punto de vista temático y estilístico, una doble mirada (fondo y forma) que cobra su máxima significación a la luz de la política rancièriana.
PauLatinas. Temporalidad de la escritura en las trayectorias de Leonor Courtoisie y Fernanda Trías
Authors: Sánchez Tamara Albarracín
Published: February 2025

Desde una perspectiva sociológica, este artículo propone un análisis del impacto de los dispositivos (inter)nacionales de apoyo a la creación sobre las trayectorias y prácticas literarias. Se enfoca en las “geo-biografías” de dos narradoras uruguayas contemporáneas: Leonor Courtoisie y Fernanda Trías, cuyas prácticas artísticas se enmarcan en una “epistemología feminista de la creación”. Este artículo pretende difundir y dialogar con estos pensamientos críticos que ponen en tensión el discurso institucional. Estos dispositivos, que se enmarcan en relaciones transnacionales de dominación, generan una temporalidad productivista y turbu-lenta de la literatura.
La lentitud del intersticio: evasión y temporalidad en la narrativa en español del siglo XXI
Authors: Vidal Borja Cano
Published: February 2025

Este artículo analiza textos de María Sonia Cristoff, Federico Falco, Cynthia Rimsky y Remedios Zafra a partir de la noción de intersticio y su configuración como dispositivo de resistencia a la velocidad imperante en la urbe contemporánea. Desde este planteamiento, se explora la composición narrativa de refugios que, incluso inmersos en el entramado de la ciudad, generan un ritmo lento, apostando por el instante como base para articular otros tiempos. Asimismo, se atenderá a sus características formales, como la inserción de documentos e imágenes que ralentizan la experiencia de lectura, el vínculo entre lenguaje y paisaje o el hibridismo genérico.
La disrupción de la temporalidad en Volver a dónde, de Antonio Muñoz Molina
Authors: García Ane Matres
Published: February 2025

Volver a dónde (2021) es un libro de Antonio Muñoz Molina sobre la vida cotidiana de un narrador homónimo durante la pandemia del COVID-19 y la nueva normalidad. Esta obra propone, en cuanto a contenido, una vida pausada y reflexiva y critica la aceleración de la sociedad. En cuanto a estilo, también genera un libro que desafía esa sociedad de la velocidad y productividad. Sin embargo, este nuevo proceder no está libre de las costumbres de la anterior vida cotidiana acelerada, por lo que hay tensiones formales generadas por la velocidad de la creación literaria, la fragmentación y la productividad.
Modos de puntuar el tiempo en producciones de literatura digital argentina
Authors: Mugica Fernanda
Published: February 2025

En este trabajo, nos interesa estudiar articuladamente una serie de producciones de literatura digital argentina : The Spell (Solaas 2021), Un segundo (Scarlato 2023), Trenza (Costello 2020) y Voy a tener suerte (autor anónimo 2020). Sostenemos que se trata de producciones que escenifican modos divergentes de puntuar el tiempo en el semiocapitalismo (Berardi) y en un contexto de gubernamentalidad algorítmica (Rouvroy y Berns). Desde allí, nos interrogamos respecto de la potencia política de estas prácticas que privilegian la lentitud o trabajan con la aceleración desde dentro, para cuestionar la automatización desde la automatización misma.

Social Justice Realities for Women Leaders in South African Schools
Authors: Musundire Austin
Published: February 2025

The paper presents findings of systematic literature review making use of findings, conclusions and recommendations from 32 articles related to female school principals in South Africa. This was aimed at establishing social justice realities among women school leaders. The study identified that despite the intentions of the South African Department of Education and the constitutional rights which allows women equal opportunities of employment and leadership at the workplace, this is not implemented. The following four thematic areas linked to challenges faced by women managers were identified: (1) Discrimination and prejudice (2) Balancing work, family conflicts (3) Community bias and (4) Lack of professional and family support. It was concluded that social justice among woman educators was not observed to address women leadership inequalities. The paper provided theoretical and practical contributions on the body of knowledge towards social justice recognition of women leadership in schools for promoting leadership opportunities and prospects.

Ethical and Legal Considerations in Digital Counseling
Authors: Shafik Wasswa
Published: February 2025

As counselor practices and the counseling profession continue to evolve and change, digital counseling offered on digital platforms makes traditional educational and mental health services more accessible than they have ever been. Therapy sessions increasingly are virtual or conducted through direct messaging platforms and chatbots, rather than a 1-to-1 (face-to-face) model. Virtual therapy has grown significantly over the past several years, with very few of those clients ever seeing an actual person, counselor, or therapist. However, counseling online is not better than or greater than face-to-face counseling and is not for everyone. For many, remote technology adds to the therapeutic conversation, but makes it difficult to provide privacy, confidentiality, emotional tactile presence, and possibly an erosion of relationships between client and therapist. As a continually evolving field, it is essential for current and future counseling and therapist practitioners to stay up to date on current ethical and legal standards pertaining to digital counseling.
