La transformación curricular: Un paradigma emergente como aporte a la educación holística
Authors: Cardozo Cruz Jonatan Julian , Mejia Guarin Sandra Milena , Alvarez Giraldo Neidy Bibiana 
Published: January 2024

Esta publicación científica pretende exponer algunas de las tendencias curriculares contemporáneas que están directamente relacionadas con el proceso de enseñanza-aprendizaje de los estudiantes, las prácticas pedagógicas docentes, la calidad educativa, las habilidades que desarrollan los educandos inmersos en diferentes contextos socio-culturales y educativos.
En consideración a lo anterior, no solo se presenta la relevancia que tiene en la actualidad el currículo frente a la mitigación de la brecha entre la escuela y la sociedad, sino también la interacción e interrelación que debe existir entre la teoría y práctica del mismo; a su vez, se resalta la importancia y flexibilidad del currículo para la formación de seres humanos integrales dentro de las instituciones educativas, teniendo en cuenta el contexto real y por ende su incidencia en los procesos de transformación social, de donde se reconfigura como un paradigma emergente que incide de manera pertinente en la educación holística.
La metodología desarrollada, en la cual se argumentó esta propuesta, se enfoca en la investigación cualitativa, la técnica para el rastreo e identificación de la información empleada fue la revisión documental, en donde de manera complementaria se recurre a la hermenéutica como medio para entender, aclarar y repensar acerca de la información recopilada de los diferentes antecedentes bibliográficos analizados.
La principal deducción a la que se llego es que, en la época actual la educación enfrenta múltiples retos en un mundo en constante evolución en donde la modificación y mejoramiento continuo del currículo, la renovación de las prácticas pedagógicas, el desarrollo de habilidades sociales, personales, profesionales e interdisciplinares en el estudiante promoverán una transformación en la manera holística de ver el mundo e interactuar con él; en consideración a esta realidad educativa es imprescindible reflexionar desde múltiples puntos de vista los fenómenos que emergen del acto educativo, el cual pretenderá dar respuesta a las necesidades que demande el contexto socio-cultural en el que habiten los actores que intervienen en el proceso de enseñanza-aprendizaje en relación al currículo y como aporte a la educación holística.
Spin Dynamics of Planets in Resonant Chains
Authors: Millholland Sarah C. , Lara Teo , Toomlaid Jan 
Published: January 2024

Abstract
About a dozen exoplanetary systems have been discovered with three or more planets participating in a sequence of mean-motion resonances. The unique and complex architectures of these so-called “resonant chains” motivate efforts to characterize their planets holistically. In this work, we perform a comprehensive exploration of the spin-axis dynamics of planets in resonant chains. Planetary spin states are closely linked with atmospheric dynamics and habitability and are thus especially relevant to resonant chains like TRAPPIST-1, which hosts several temperate planets. Considering a set of observed resonant chains, we calculate the equilibrium states of the planetary axial tilts (“obliquities”). We show that high-obliquity states exist for ∼60% of planets in our sample, and many of these states can be stable in the presence of tidal dissipation. Using case studies of two observed systems (Kepler-223 and TOI-1136), we demonstrate how these high-obliquity states could have been attained during the initial epoch of disk-driven orbital migration that established the resonant orbital architectures. We show that the TRAPPIST-1 planets most likely have zero obliquities, with the possible exception of planet d. Overall, our results highlight that both the orbital and spin states of resonant chains are valuable relics of the early stages of planet formation and evolution.

Published: January 2024

Abstract
Common envelope evolution (CEE) is vital for forming short-orbital-period compact binaries. It covers many objects, such as double compact merging binaries, Type Ia supernovae progenitors, binary pulsars, and X-ray binaries. Knowledge of the common envelope (CE) ejection efficiency still needs to be improved, though progress has been made recently. Short-orbital-period hot subdwarf B star (sdB) plus white dwarf (WD) binaries are the most straightforward samples with which to constrain CEE physics. We apply the known orbital period–WD mass relation to constrain the sdB progenitors of seven sdB+WD binaries with a known inclination angle. The average CE efficiency parameter is 0.32. This is consistent with previous studies. However, the CE efficiency need not be constant, but a function of the initial mass ratio, based on well-constrained sdB progenitor mass and evolutionary stage. Our results can be used as physical inputs for binary population synthesis simulations of related objects. A similar method can also be applied to study other short-orbital-period WD binaries.
Asteroseismic Inversions for Internal Sound Speed Profiles of Main-sequence Stars with Radiative Cores

Published: January 2024

Abstract
The theoretical oscillation frequencies of even the best asteroseismic models of solar-like oscillators show significant differences from observed oscillation frequencies. Structure inversions seek to use these frequency differences to infer the underlying differences in stellar structure. While used extensively to study the Sun, structure inversion results for other stars have so far been limited. Applying sound speed inversions to more stars allows us to probe stellar theory over a larger range of conditions, as well as look for overall patterns that may hint at deficits in our current understanding. To that end, we present structure inversion results for 12 main-sequence solar-type stars with masses between 1 and 1.15 M
⊙. Our inversions are able to infer differences in the isothermal sound speed in the innermost 30% by radius of our target stars. In half of our target stars, the structure of our best-fit model fully agrees with the observations. In the remainder, the inversions reveal significant differences between the sound speed profile of the star and that of the model. We find five stars where the sound speed in the core of our stellar models is too low and one star showing the opposite behavior. For the two stars in which our inversions reveal the most significant differences, we examine whether changing the microphysics of our models improves them and find that changes to nuclear reaction rates or core opacities can reduce, but do not fully resolve, the differences.
Fluid Mixing during Phase Separation in Crystallizing White Dwarfs
Authors: Montgomery M. H. , Dunlap Bart H. 
Published: January 2024

Abstract
Accurate models of cooling white dwarfs must treat the energy released as their cores crystallize. This phase transition slows the cooling by releasing latent heat and also gravitational energy, which results from phase separation: liquid C is released from the solid C/O core, driving an outward carbon flux. The Gaia color–magnitude diagram provides striking confirmation of this theory by revealing a mass-dependent overdensity of white dwarfs, indicating slowed cooling at the expected location. However, the observed overdensity is enhanced relative to the models. Additionally, it is associated with increased magnetism, suggesting a link between crystallization and magnetic field generation. Recent works aimed at explaining an enhanced cooling delay and magnetic field generation employ a uniform mixing prescription that assumes large-scale turbulent motions; we show here that these calculations are not self-consistent. We also show that thermohaline mixing is most likely efficient enough to provide the required chemical redistribution during C/O phase separation, and that the resulting velocities and mixing lengths are much smaller than previous estimates. These reduced fluid motions cannot generate measurable magnetic fields, suggesting any link with crystallization needs to invoke a separate mechanism. Finally, this mixing alters the chemical profiles, which in turn affects the frequencies of the pulsation modes.
The Long-term Spin-down Trend of Ultraluminous X-Ray Pulsar M82 X-2
Authors: Liu Jiren 
Published: January 2024

Abstract
The discovery in 2014 of the pulsation from the ultraluminous X-ray source (ULX) M82 X-2 has changed our view of ULXs. Because of the relatively short baseline over which pulsations have been detected so far, M82 X-2's spin state had been assumed to be in an equilibrium state. Using Chandra and XMM-Newton archive data, we are able to investigate the pulsation of M82 X-2 back to 2005 and 2001. The newly determined spin frequencies clearly show a long-term spin-down trend. If this trend is caused by magnetic threading, we infer a dipolar magnetic field of ∼1.2 × 1013 G and that a mild beaming factor (∼4) is needed to match the braking torque with the mass accretion torque. On the other hand, there are NuSTAR observations showing instantaneous spin-down behaviors, which might favor a variable prograde/retrograde flow scenario for M82 X-2.
Géographie sociale : quel retour du sujet et de l’acteur ?
Authors: Di Méo Guy 
Published: January 2024

L’auteur situe sa conception de la géographie sociale dans la filiation de l’école qui émergea, au cours des années 1970 et 1980, dans plusieurs universités de l’ouest et du sud (est et ouest) de la France. Il la décrit comme une géographie complexe s’attachant à définir la façon dont les interrelations de rapports sociaux et spatiaux, tissant l’espace social, produisent, en puisant dans sa propre substance, des espaces-temps singuliers : lieux, territoires, réseaux… Pour engendrer ces structures spatiales comportant de fortes charges symboliques, imaginaires et identitaires, l’intervention concrète de systèmes d’acteurs est indispensable. Leur spatialisation crée des discontinuités géographiques et des formes variées de distinction territoriale qui se cristallisent autour d’enjeux sociaux, économiques ou politiques. La place prépondérante accordée au sujet humain, décliné dans ses formes de socialisation croissante, de son statut de conscience et de corps jusqu’à celui de personne et d’acteur, impose à cette géographie sociale une démarche et des méthodes de recherche spécifiques. L’une et les autres privilégient une axiomatique retenant quatre types d’espaces finalement complémentaires bien que relevant d’approches philosophiques différentes que d’aucuns pourraient juger inconciliables. Leur recours conjoint offre en effet la possibilité d’une lecture globale et compréhensive des sociétés tissées dans leurs espaces. Il s’agit des catégories de l’espace du monde vécu, associé à une vision kantienne et phénoménologique, de l’espace cartésien fondé sur la séparation de l’esprit et de la matière / étendue, de l’espace considéré comme un pur produit social, enfin de l’espace post-moderne et hyper-réel de la simulation et du simulacre. C’est en usant de ces corpus théoriques que procède la géographie sociale défendue par l’auteur.
Géographie et travail
Authors: Tabusi Massimiliano 
Published: January 2024

Même si l’analyse géographique apparaît indissociablement liée par nature à l’étude du travail, comme facteur de production, agent de modelage du territoire ou encore comme fondement même de la cohésion sociale, une véritable géographie du travail ne semble pas s’être affirmée jusqu’à présent. Cet essai formule l’hypothèse que l’analyse géographique a eu tendance, mises à part quelques exceptions significatives, à identifier l’étude du travail à celle de la répartition de la population active entre les différents secteurs d’activité, à la localisation géographique des bassins d’emploi ou encore à l’individualisation des principales variables relatives au travail (coût du travail, spécialisation, degré de syndicalisation, niveau de protection sociale, etc.). Une telle approche semble de fait avoir attribué au travail, dans le cadre de l’analyse géographique, une fonction accessoire par rapport à celle de la géographie du capital, comme étant l’agent principal de la « création » et de l’évolution du territoire. Dans cet essai, à travers la pensée d’auteurs qui se sont occupés plus ou moins directement de travail et de géographie, on analyse quelques passages de l’étude théorique particulièrement significatifs pour expliquer cette évolution disciplinaire. Enfin, en recourant aux récentes évolutions de la géographie radicale anglo-saxonne, on met en évidence, à partir d’une perspective d’analyse géographique économique et sociale, l’utilité de l’étude du travail comme véritable acteur territorial.
Considérations sur les partages du monde entre le Nord et le Sud et hypothèses de scénarios géopolitiques
Authors: Mazzetti Ernesto 
Published: January 2024

La population mondiale augmente et, dans le même temps, elle devient plus urbaine. Mais ce processus d’expansion constante de la société métropolitaine ne signifie pas que les conditions de vie de plus de la moitié des habitants de la planète s’uniformisent. Au cours des dernières décennies, le développement des villes et des métropoles a vu de plus en plus l’opposition de paysages urbains profondément dissemblables entre le Nord et le Sud du monde. La différence se perçoit non pas tant au niveau de la matérialité du tissu édifié ou des flux de véhicules, que par des éléments immatériels : les conditions sociales et les caractères culturels dominants. Une division profonde existe entre les « agglomérations de la souffrance » et les « métropoles de l’opulence ». Les problèmes connexes à la coexistence de paysages urbains et sociaux différents donnent naissance aux défis les plus complexes que la réalité du nouveau siècle nous présente. En dérivent des risques d’une opposition reproduite non plus seulement au plan international entre « McWorld » et « Jihad », mais à l’intérieur même des métropoles de l’Occident, qui sont les destinations de flux ininterrompus d’immigration, soumises à l’épreuve difficile de la multiculturalité, du multi-ethnisme et de l’intégration.
De la non-durabilité à la qualité urbaine : politiques urbanistiques et scénarios pour le développement territorial et l’équilibre social
Authors: Miani Franca 
Published: January 2024

Cette contribution propose d’insérer les processus de transformation urbaine au centre d’une réflexion de géographie sociale. Des problèmes du sprawl urbain à ceux du logement, des thèmes de la qualité et de la durabilité à l’expérimentation de modèles de développement urbanistique innovants, qui prévoient la requalification du tissu urbain déjà existant, il est possible d’observer comment chaque action entreprise dans la ville engendre des conséquences sociales et des retombées spécifiques dans des contextes locaux. Dans un scénario encore en voie de transformation, qui ne se réduit pas à identifier des lignes de conduite univoques et absolues, les actions de gouvernement, surtout à l’échelle locale, acquièrent un poids fondamental. Que peuvent faire les politiques urbanistiques pour adapter les structures urbaines aux nouvelles fonctions et aux nouveaux citoyens ? Comment atteindre la durabilité urbaine dans un monde qui, selon de nombreux scientifiques, se dirige à grands pas vers l’entropie du système ? Dans ce cadre extrêmement varié et fugace dans la délimitation de sa définition et en coprésence de scénarios assez divers que la mondialisation économique et technologique nous impose, il devient essentiel, avant même d’entamer des planifications ou des projets de constructions plus ou moins conformes aux paysages existants, de réfléchir au sens et aux conséquences sociales que de telles interventions pourront provoquer.

Abstract
In response to microbial infection, the nonclassical Ag-presenting molecule MHC class I–related protein 1 (MR1) presents secondary microbial metabolites to mucosal-associated invariant T (MAIT) cells. In this study, we further characterize the repertoire of ligands captured by MR1 produced in Hi5 (Trichoplusia ni) cells from Mycobacterium smegmatis via mass spectrometry. We describe the (to our knowledge) novel MR1 ligand photolumazine (PL)V, a hydroxyindolyl-ribityllumazine with four isomers differing in the positioning of a hydroxyl group. We show that all four isomers are produced by M. smegmatis in culture and that at least three can induce MR1 surface translocation. Furthermore, human MAIT cell clones expressing distinct TCR β-chains differentially responded to the PLV isomers, demonstrating that the subtle positioning of a single hydroxyl group modulates TCR recognition. This study emphasizes structural microheterogeneity within the MR1 Ag repertoire and the remarkable selectivity of MAIT cell TCRs.
Surgical management of a case of double optic disc pits with maculopathy
Authors: Nadig Ramya R , Ratra Dhanashree 
Published: January 2024

Background:
Double optic disc pit maculopathy is a rare entity. It can be difficult to manage because of excessive leakage and chronic maculopathy.

Purpose:
To describe surgical management in a case of double optic disc pits with maculopathy.

Synopsis:
A 42-year-old male presented with double optic disc pits with macular detachment in the left eye. The best-corrected visual acuity (BCVA) was 20/60, N12. Preoperative OCT showed the presence of two disc pits. The macular region had large retinoschisis and subretinal fluid (SRF) with a central foveal thickness of 879 microns and loss of the ellipsoid zone. A shallow communication from the temporal aspect of the disc to the submacular area was also noted. Among the options of observation, laser photocoagulation, and surgery, the patient opted for surgical management.

Surgical technique:
A standard-3 port 23-gauge pars plana vitrectomy was done. After staining the ILM with brilliant blue, ILM peeling was done with the help of forceps and Finesse loop. ILM flaps were inverted over to cover the optic disc pits and sealed with a drop of fibrin glue. Next, 20% SF6 gas was used for tamponade. Pre- and post-surgery parameters such as visual acuity and OCT were evaluated.

Postoperative evaluation:
After 6 weeks, left eye BCVA was 20/40 with OCT showing reduced SRF and reduced intraretinal schisis with a foveal thickness of 546 microns. At 3 months of follow-up, the vision in the left eye had improved to 20/30 with further reduction in the retinoschisis and foveal thickness of 482 microns.

Highlights:
In this interesting case, we demonstrate a unique way of sealing the defect surgically by vitrectomy and inverted ILM flap with fibrin glue over the disc pits. Despite sealing the maculopathy is slow to resolve.

Disinsert, retract and rotate technique of plaque brachytherapy
Authors: Lomi Neiwete , Chawla Bhavna , Das Deepsekhar 
Published: January 2024

Background:
Plaque brachytherapy is commonly used in the management of choroidal melanomas. The surgical steps usually involve creating a conjunctival peritomy, fixing the recti muscles, with or without disinserting them based on the location of the lesion, and placing the plaque. The inferior oblique muscle is attached close to the macula, and in cases of perimacular or peripapillary lesions, the muscle needs to be sacrificed.

Purpose:
The authors here demonstrate a novel technique of placing radioactive plaque without disinserting the inferior oblique muscle in cases of perimacular or peripapillary choroidal melanomas.

Synopsis:
The video demonstrates how the “disinsert, retract, and rotate technique” of brachytherapy plaque placement can be performed and what are the fundamentals behind this technique. The authors have performed this procedure multiple times and there has been no incidence of plaque tilt or migration.

Highlights:
In perimacular and peripapillary choroidal melanoma brachytherapy plaque placement, the inferior oblique muscle can be spared. The simple technique does not lead to any tilt or migration of the radioactive plaque.

Evaluation of the macular sensitivity and retinal ganglion cell layer in unilateral amblyopia
Authors: Çiçek Nilay , Demirayak Bengi , Yigit Fadime U 
Published: January 2024

Purpose:
To assess macular sensitivity and fixation pattern obtained by microperimetry and ganglion cell complex (GCC) obtained by optical coherence tomography (OCT) in cases with unilateral amblyopia and to compare with control.

Methods:
The study was conducted with 30 patients with amblyopia, aged 5–18 years, and 30 control eyes of healthy children in the same age group. Participants underwent full ophthalmological examination. Macular sensitivity, stabilization, and location of fixation values were measured using microperimetry. The GCC values were obtained by OCT. Measurements were compared between amblyopic eyes, fellow eyes, and controls. Any correlation between GCC, macular sensitivity, and fixation was investigated. P < 0.05 was considered statistically significant.

Results:
The mean age was 10.13 ± 3.49 years in the amblyopia group and 11.53 ± 2.7 years in the control group. Three groups were formed: amblyopic eyes (Group 1, n = 30), fellow eyes (Group 2, n = 30), and control eyes (Group 3, n = 30). The macular sensitivity values were found highest in the control group (P = 0.007). Bivariate contour ellipse area 1, which is the numerical value of fixation stabilization, was measured to be the lowest in the control group (P < 0.0001). In the analysis among the three groups, no significant difference was observed in terms of the GCC (P = 0.229). In the correlation analyses, a significant correlation was detected between macular sensitivity and GCC values in amblyopic eyes.

Conclusion:
In amblyopic eyes, the macular sensitivity was significantly lower and the GCC thickness was found to be in a positive correlation with macular sensitivity.
On quantitative metastability for accretive operators
Authors: Sipoş Andrei 
Published: January 2024

Kohlenbach and the author have extracted a rate of metastability for approximating curves associated to continuous pseudocontractive self-mappings in Banach spaces which are uniformly convex and uniformly smooth, whose convergence is due to Reich. In this note, we show that this result may be extended to Reich’s original convergence statement involving resolvents of accretive operators.
Ecclesiastes
Authors: Enns Peter 
Published: January 2024

Ecclesiastes is an Old Testament book with a long history of diverse and contradictory interpretations. Even basic questions -- who wrote the book, when, and for what purpose -- perennially plague scholars. The book's theological message is likewise elusive, hidden in riddles and convoluted trains of thought that twist and turn back upon themselves.
In this expert commentary on Ecclesiastes, Peter Enns neither disregards nor attempts to resolve the book's many theological tensions and ambiguities. Rather, he shows how these form the backdrop against which the author struggles to show readers the proper path forward in their journeys of faith -- remaining true to the tradition to "fear God and keep the commands" despite the apparent futility of human existence.
