El sigiloso poder de los medios
Authors: Meneses Espinosa Paulina
Published: March 2024

El presente texto pretende mostrar la influencia que los medios, en especial los audiovisuales, tienen en la opinión pública, y cómo han sido desaprovechados para acercar a las masas a contenidos e información académicos. Para la presente investigación se aborda el tema de los neutrinos, partículas que todavía son un enigma para la Física pero que se cree son de gran relevancia para conocer muchos aspectos del universo y la humanidad, en conjunto con la serie de televisión Stranger Things (2016) que en su trama muestra la posibilidad de que exista un mundo “oscuro” creado de neutrinos debajo del habitable, para comprobar como el interés y la motivación cambian cuando un tema complejo se introduce a través de algo cotidiano o socialmente popular.

El presente artículo estuvo dirigido al análisis y revisión documental sobre la “Neuroeducación como estrategia innovadora para el Desarrollo de Emprendimientos en la Educación Media”. Introducir al mundo moderno la aplicación de la Neuroeducación, como un nuevo modelo mental en el ámbito educativo, busca desarrollar habilidades y destrezas que permitan a las nuevas generaciones, utilizar el cerebro para pensar, diseñar, innovar e implementar las mejores formas, para fortalecer el emprendimiento en la administración y gestión educativa. El estudio se abordó desde la investigación analítica documental y bibliográfica descriptiva. Esta metodología permitió indagar información adecuada en la construcción de la parte teórica, así como también el uso de sitio de publicaciones científicas reconocidos. Tras el análisis y revisión de los referentes teóricos se encontró que la neuroeducación como estrategia innovadora mejora los resultados de aprendizaje de los estudiantes en diversas área educativas; sin embargo, esto podría verse limitado por la comprensión y el enfoque que los docentes tienen del desarrollo de emprendimientos. Por tanto, se requiere más investigación para fundamentar las implicaciones de la misma en los estudiantes, ya su campo de estudio aun es incipiente  y continua en progreso.
Habilidades directivas del gestor municipal en la participación ciudadana con los representantes de la sociedad civil de Yarinacocha, 2022
Authors: Amias Ruiz Pedro
Published: March 2024

Esta tesis ha tenido como propósito determinar las habilidades directivas del gestor municipal en la participación ciudadana con los representantes de la sociedad civil de Yarinacocha, 2022.  En cuanto a la metodología, la investigación se caracterizó por ser básica, no experimental, nivel explicativo, de enfoque cuantitativo, diseño   transversal y causal. La población lo conformaron 1 468 personas y la muestra por 305 personas, todos ellos ciudadanos representantes de los asentamientos humanos y caseríos de la localidad. Se empleó dos instrumentos cuestionarios para la recolección de datos; lo mismo que se procesaron usando el programa Microsoft Excel 2010 y el programa estadístico SPSS 24.0 a efectos de encontrar los resultados y lograr los objetivos de investigación. Los hallazgos muestran que hay una frecuencia acumulada del 59,4% y 50,5% respectivamente, para la variable participación ciudadana y habilidades directivas, el cual explica un alto porcentaje de desaprobación con respecto a los niveles de ambas variables. También se encontró una significación aproximada de 0,000, es decir, el p valor ha sido menor a 0.05 (p < 0.05), lo que permitió aceptar la hipótesis alternativa y consecuentemente rechazar la hipótesis nula.  Asimismo, con respecto a su grado de significancia según el coeficiente de Tau-b de Kendall fue de 0,198, lo que se interpretó como un efecto positivo muy bajo. Esto muestra que el nivel de habilidades de gestión de los líderes municipales tiene un impacto en el desarrollo del nivel de participación ciudadana, pero el efecto no es grande. Sin embargo, dada su importancia en la creación de valor público en áreas de población vulnerable, este tema merece especial atención. Finalmente se concluyó que las habilidades directivas de los gestores municipales tienen una influencia significativa en la participación de los vecinos representantes de la sociedad civil de la localidad de Yarinacocha.
The Impact Analysis of Bauxite Downstreaming on the Indonesian Economy: Case Study in PT Bintan Alumina Indonesia
Authors: Shinta Jessica Andrea , Wikarya Uka
Published: March 2024

This research analyzes the impact of investment and bauxite downstream activities by PT Bintan Alumina Indonesia (PT BAI) on the Indonesian economy using the input-output method applied to the Riau Islands Province, West Kalimantan Province and Indonesia. The imposition of stimulus on sectors related to the construction phase and operational phase of the alumina and aluminum industry in the Galang Batang SEZ is the concept that underlies how final demand in other sectors is affected. Economic improvement is characterized by increased output, GDRP, people's income, and the creation of job opportunities. During the construction phase of PT BAI (2016-2029), it generally had a positive impact on the increase in output, income, average GRDP, and average job creation in 52 industrial sectors in the Riau Islands Province. During the operational phase, calculated through three scenarios applied to the Riau Islands Province, West Kalimantan, and Indonesia, with the assumption of full downstreaming of PT BAI's products into the domestic market, shows the greatest impact. The impact includes the increase of Indonesia's output value until 2030 reaching IDR 547.07 trillion, an average annual GDP growth of 0.099 percent, a national income increases until 2030 reaching IDR 74.22 trillion, and an average job creation of 107,105 people per year in 52 industrial sectors in Indonesia. To achieve the optimal target of PT Bintan Alumina Indonesia's (BAI) presence in the domestic bauxite value chain, strengthening the downstream process and downstream industries of alumina and aluminum domestically is needed. Fiscal incentives, the establishment of pro-downstream regulations, and investor protection are crucial to implement.

About 40 trans-Neptunian binaries (TNBs) have fully determined orbits with about 10 others being solved except for breaking the mirror ambiguity. Despite decades of study, almost all TNBs have only ever been analyzed with a model that assumes perfect Keplerian motion (e.g., two point masses). In reality, all TNB systems are non-Keplerian due to nonspherical shapes, possible presence of undetected system components, and/or solar perturbations. In this work, we focus on identifying candidates for detectable non-Keplerian motion based on sample of 45 well-characterized binaries. We use MultiMoon, a non-Keplerian Bayesian inference tool, to analyze published relative astrometry allowing for nonspherical shapes of each TNB system’s primary. We first reproduce the results of previous Keplerian fitting efforts with MultiMoon, which serves as a comparison for the non-Keplerian fits and confirms that these fits are not biased by the assumption of a Keplerian orbit. We unambiguously detect non-Keplerian motion in eight TNB systems across a range of primary radii, mutual orbit separations, and system masses. As a proof of concept for non-Keplerian fitting, we perform detailed fits for (66652) Borasisi-Pabu, possibly revealing a J
2 ≈ 0.44, implying Borasisi (and/or Pabu) may be a contact binary or an unresolved compact binary. However, full confirmation of this result will require new observations. This work begins the next generation of TNB analyses that go beyond the point mass assumption to provide unique and valuable information on the physical properties of TNBs with implications for their formation and evolution.

Massive infrared dark clouds (IRDCs) are considered to host the earliest stages of high-mass star formation. In particular, 70 μm dark IRDCs are the colder and more quiescent clouds. At a scale of about 5000 au using formaldehyde (H2CO) emission, we investigate the kinetic temperature of dense cores in 12 IRDCs obtained from the pilot Atacama Large Millimeter/submillimeter Array Survey of 70 μm dark High-mass clumps in Early Stages (ASHES). Compared to the 1.3 mm dust continuum and other molecular lines, such as C18O and deuterated species, we find that H2CO is mainly sensitive to low-velocity outflow components rather than to quiescent gas expected in the early phases of star formation. The kinetic temperatures of these components range from 26 to 300 K. The Mach number reaches about 15 with an average value of about 4, suggesting that the velocity distribution of gas traced by H2CO is significantly influenced by a supersonic nonthermal component. In addition, we detect warm line emission from HC3N and OCS in 14 protostellar cores, which requires high excitation temperatures (E

u
/k ∼ 100 K). These results show that some of the embedded cores in the ASHES fields are in an advanced evolutionary stage, previously unexpected for 70 μm dark IRDCs.
Stellar Cycle and Evolution of Polar Spots in an M+WD Binary
Authors: Zhao Xinlin , Wang Song , Li Xue , Xiang Yue , Xu Fukun , Gu Shenghong , Du Bing , Liu Jifeng
Published: March 2024

Stellar activity cycles reveal continuous relaxation and induction of magnetic fields. The activity cycle is typically traced through the observation of cyclic variations in total brightness or Ca H&K emission flux of stars, as well as cyclic variations in the orbital periods of binary systems. In this work, we report the identification of a semidetached binary system (TIC 16320250) consisting of a white dwarf (0.67 M
⊙) and an active M dwarf (0.56 M
⊙). The long-term multiband optical light curves spanning twenty years revealed three repeated patterns, suggestive of a possible activity cycle of about 10 years of the M dwarf. Light-curve fitting indicates the repeated variation is caused by the evolution, particularly the motion, of polar spots. The significant Ca H&K, Hα, ultra-violet, and X-ray emissions imply that the M dwarf is one of the most magnetically active stars. We propose that in the era of large time-domain photometric sky surveys (e.g., ASAS-SN, Zwicky Transient Facility, LSST, Sitian), long-term light-curve modeling can be a valuable tool for tracing and revealing stellar activity cycle, especially for stars in binary systems.
Ejection Patterns in the DG Tau Jet over the Last 40 yr: Insights into Mass Accretion Variability*
Authors: Pyo Tae-Soo , Hayashi Masahiko , Takami Michihiro , Beck Tracy L.
Published: March 2024

We aim to clarify the link between mass accretion and ejection by analyzing DG Tau’s jet observations from optical and near-infrared data spanning 1984–2019, alongside photometric variations between 1983 and 2015. We classified 12 moving knot groups among 17 total knot groups based on their constant proper motions and comparable radial velocities. A strong correlation emerges between the deprojected flow velocities of the knots and the photometric magnitudes of DG Tau. From 1983 to 1995, as the deprojected ejection velocities surged from ∼273 ± 15 to ∼427 ± 16 km s−1, the photometric magnitudes (V) concurrently brightened from 12.3 to 11.4. Notably, when DG Tau became brighter than 12.2 in the V band, its (B − V) color shifted bluer than its intrinsic color range of K5–M0. During this period, the launching point of the jet in the protoplanetary disk moved closer to 0.06 au from the star in 1995. Following a V magnitude drop from 11.7 to 13.4 in 1998, the star may have experienced significant extinction due to a dust wall created by the disk wind during the ejection of the high-velocity knot in 1999. Since then, the magnitude became fainter than 12.2, the (B − V) and (V − R) colors became redder, and the deprojected velocities consistently remained below 200 km s−1. The launching point of the jet then moved away to ∼0.45 au by 2008. The prevailing factor influencing photometric magnitude appears to be the active mass accretion causing the variable mass ejection velocities.
Theoretical Spectroscopic Study of Isopropyl Alcohol (CH3-CHOH-CH3)
Authors: Salah Mohammed , Marakchi Khadija , Komiha Najia , Senent Maria Luisa
Published: March 2024

Accurate spectroscopic parameters of isopropyl alcohol, a volatile organic compound present on Earth and in extraterrestrial atmospheres, are provided. The work pursues the study of the far-infrared region, describing the distribution of the low-lying vibrational energy levels that can be populated at very low temperatures, having effects on the detectability and identification. The potential energy surface shows 27 almost equivalent minima producing 27 subcomponents of the levels due to tunneling effects. Computations have been performed using highly correlated ab initio calculations, accurate enough to distinguish between the rotational parameters of the two quasi-identical conformers gauche and trans. A variational procedure in three dimensions depending on three interacting internal rotations, the internal rotation of the two methyl groups and the internal rotation of the hydroxyl group, is employed to compute the energies. The 27 subcomponents of the ground vibrational state can be grouped into three series of nine energy levels located around 0.000, 1.693, and 81.927 cm−1 whose energy difference is due to the OH torsion effect. The nine subcomponents integrated in each series derive from the torsion of the two methyl groups. The computations reproduce accurately the available experimental data. New predicted properties can help the spectroscopic analysis of the rotational-vibrational spectra in the gas phase and further detections of vibrationally excited isopropyl alcohol.
Atmospheric Chemistry of Secondary and Hybrid Atmospheres of Super Earths and Sub-Neptunes
Authors: Tian Meng , Heng Kevin
Published: March 2024

The atmospheres of small exoplanets likely derive from a combination of geochemical outgassing and primordial gases left over from formation. Secondary atmospheres, such as those of Earth, Mars, and Venus, are sourced by outgassing. Persistent outgassing into long-lived, primordial, hydrogen–helium envelopes produces hybrid atmospheres of which there are no examples in the solar system. We construct a unified theoretical framework for calculating the outgassing chemistry of both secondary and hybrid atmospheres, where the input parameters are the surface pressure, oxidation, and sulfidation states of the mantle, as well as the primordial atmospheric hydrogen, helium, and nitrogen content. Nonideal gases (quantified by the fugacity coefficient) and nonideal mixing of gaseous components (quantified by the activity coefficient) are considered. Both secondary and hybrid atmospheres exhibit a rich diversity of chemistries, including hydrogen-dominated atmospheres. The abundance ratio of carbon dioxide to carbon monoxide serves as a powerful diagnostic for the oxygen fugacity of the mantle, which may conceivably be constrained by James Webb Space Telescope spectra in the near future. Methane-dominated atmospheres are difficult to produce and require specific conditions: atmospheric surface pressures exceeding ∼10 bar, a reduced (poorly oxidized) mantle, and diminished magma temperatures (compared to modern Earth). Future work should include photochemistry in these calculations and clarify the general role of atmospheric escape. Exoplanet science should quantify the relationship between the mass and oxygen fugacity for a sample of super Earths and sub-Neptunes; such an empirical relationship already exists for solar system bodies.
Ejecta–Circumstellar Medium Interaction in High-density Environment Contribution to Kilonova Emission: Application to GRB 191019A
Authors: Wang Suo-Ning , Lü Hou-Jun , Yuan Yong , Yuan Hao-Yu , Rice Jared , Chen Meng-Hua , Liang En-Wei
Published: March 2024

The nearby long-duration GRB 191019A recently detected by Swift lacks an associated supernova and belongs to a host galaxy with little star formation activity, suggesting that the origin of this burst is the result of a merger of two compact objects with dynamical interactions in a high-density medium of an active galactic nucleus. Given the potential motivation of this event, and given that it occurs in such a high-density environment, the ejecta–circumstellar medium (CSM) interaction cannot be ignored as possibly contributing to the kilonova emission. Here, we theoretically calculate the kilonova emission by considering the contribution of the ejecta–CSM interaction in a high-density environment. We find that the contribution to the kilonova emission from the ejecta–CSM interaction will dominate at a later time, and a smaller ejecta mass will have a stronger kilonova emission from the ejecta–CSM interaction. Moreover, we try to apply it to GRB 191019A, but we find that it is difficult to identify the possible kilonova emission from the observations, due to the contribution of the bright host galaxy. On the other hand, less injected mass (less than M
ej = 2 × 10−5
M
⊙) will be required if one can detect the kilonova emission associated with a GRB 191019A–like event in the future. The r-process-powered and spin energy contributions from the magnetar are also discussed.
Two High-amplitude δ Scuti–γ Doradus Hybrids Constrained by the Radial Fundamental p and Equally Spaced g Modes
Authors: Chen Xinghao , Zhang Xiaobin , Li Yan , Su Jie
Published: March 2024

Based on 2 minutes cadence TESS data, we investigate pulsations of TIC 65138566 and TIC 139729335 and discover them to be two new high-amplitude δ Scuti stars with equally spaced g modes. We recognize the radial fundamental mode f
1 = 18.3334 c d−1 and the first overtone f
3 = 23.6429 c d−1 for TIC 65138566, and identify the highest peak f
1 = 19.0955 c d−1 as the radial fundamental mode for TIC 139729335. For g modes, both stars display a regular period spacing of 2413 s. Through detailed seismological analysis, we deduce that these period-spacing patterns correspond to modes with ℓ = 1. Moreover, our analysis reveals that with increases in masses and metallicities, the star should display a higher degree of evolution to match a specific period spacing Π0. Conversely, the star should have a lower extent of evolution to match the radial fundamental mode. These two contradictory behaviors allow us to precisely obtain stellar physical parameters. TIC 65138566 and TIC 139729335 are determined to be two main-sequence stars that have almost the same range of masses and metallicities, with M = 1.36 ± 0.06 M
⊙ and Z = 0.005 ± 0.002. The hydrogen abundance in the core of TIC 65138566 is estimated to be about 0.28, while TIC 139729335 has a slightly higher value of around 0.31. Finally, we suggest that the high-amplitude δ Scuti–γ Doradus star TIC 308396022 is a main-sequence star with M = 1.54 ± 0.08 M
⊙, Z = 0.007 ± 0.001, and X
c = 0.18 ± 0.02.
The Reliability of Accretion Disk Inclination Derived from X-Ray Spectroscopy of Active Galaxies
Authors: Du Rong , Ding Yuanze , Ho Luis C. , Li Ruancun
Published: March 2024

The inclination angle of substructures in active galaxies gives insights into physical components from scales of the vicinity of the central black hole to the entire host galaxy. We use the self-consistent reflection spectral model RELXILL to measure the inclination of the inner region of accretion disks with broadband (0.3–78 keV) X-ray observations, systematically studying the reliability of this methodology. To test the capability of the model to return statistically consistent results, we analyze multiepoch joint XMM-Newton and NuSTAR data of the narrow-line Seyfert 1 galaxy I Zwicky 1 and the broad-line radio galaxy 3C 382, which exhibit different degrees of spectral complexity and reflection features. As expected, we find that adding more data for analysis narrows the confidence interval and that multiepoch joint observations return optimal measurements; however, even single-epoch data can be well fitted if the reflection component is sufficiently dominant. Mock spectra are used to test the capability of RELXILL to recover input parameters from typical single-epoch joint observations. We find that inclination is well recovered at 90% confidence, with improved constraints at higher reflection fraction and higher inclination. Higher iron abundance and corona temperature tighten the constraints as well, but the effect is not as significant as a higher reflection fraction. The spin, however, has little effect in reflection-based inclination measurements. We conclude that broadband reflection spectroscopy can reliably measure inner accretion disk inclination.
Pair Creation in Hot Electrosphere of Compact Astrophysical Objects
Authors: Prakapenia Mikalai , Vereshchagin Gregory
Published: March 2024

The mechanism of pair creation in the electrosphere of compact astrophysical objects such as quark stars or neutron stars is revisited, paying attention to evaporation of electrons and acceleration of electrons and positrons, which were previously not addressed in the literature. We perform a series of numerical simulations using the Vlasov–Maxwell equations. The rate of pair creation strongly depends on electric field strength in the electrosphere. Although Pauli blocking is explicitly taken into account, we find no exponential suppression of the pair creation rate at low temperatures. The luminosity in pairs increases with temperature and it may reach up to L
± ∼ 1052 erg s−1, much larger than previously assumed.
Do Minihalos Affect Cosmic Reionization?
Authors: Gnedin Nickolay Y.
Published: March 2024

The role of unresolved structures (“minihalos”) in determining the consumption of ionizing photons during cosmic reionization remains an unsolved problem in modeling cosmic reionization, despite recent extensive studies with small-box high-resolution simulations by Park et al. and Chan et al., because the small-box studies are not able to fully sample all environments. In this paper these simulations are combined with large-box simulations from the “Cosmic Reionization On Computers” (CROC) project, allowing one to account for the full range of environments and to produce an estimate for the number of recombinations per hydrogen atom that are missed in large-scale simulations like CROC or Thesan. I find that recombinations in unresolved minihalos are unimportant compared to recombinations produced in large-scale cosmic structures and inside more massive, fully resolved halos. Since both the Park et al. and Chan et al. studies have severe limitations, the conclusions of this paper may need to be verified with more representative sets of small-box high-resolution simulations.
First description of the female of Cyrtodactylus dianxiensis Liu & Rao, 2021, with extended diagnosis of this species (Squamata, Gekkonidae)
Authors: Zhang Dongru , Wu Yunhe , Zuo Changsheng , Yin Fawang , Liu Shuo
Published: March 2024

Cyrtodactylus dianxiensis Liu & Rao, 2021 was originally described based on only two adult male specimens from Tongbiguan Nature Reserve, Dehong Autonomous Prefecture, western Yunnan, China. So far, no information on the females of this species is available. During comprehensive herpetofaunal investigations in 2022, one female specimen of C. dianxiensis was collected from Tongbiguan Nature Reserve. The female specimen agrees well with the original description of C. dianxiensis, and also shows some slight differences in coloration. This study reported the female specimen of this species for the first time, and provided a description and photos of the female specimen; meanwhile, we extended the diagnosis of this species.

Le Père Chaillet, une théologie dans l’histoire
Authors: Ducerf Laurent
Published: March 2024

La pensée et l’engagement du P. Chaillet sont unis par une vision de l’Église inspirée de l’école de Tübingen et de Charles Möhler (1796-1838). Le lien entre la foi, la pensée et l’action montrent que c’est toujours en tant que chrétien que le P. Chaillet intervient, avant-guerre puis durant la guerre, au nom d’une conception de l’Église qui le conduit à prendre la parole face à une hiérarchie largement défaillante, sur fond d’une tension eschatologique croissante.

Toute analyse de l’histoire qui ne l’envisage pas comme une histoire sainte n’aboutit qu’à des équivoques déguisées en idoles. Après la défaite de juin 1940, l’équivoque se nommait la « collaboration » et l’idole, l’idéologie antichrétienne du racisme nazi. Pierre Chaillet et Gaston Fessard ont dénoncé la fraude qui pose que la raison du politique ressortit du domaine exclusif du pouvoir politique, sans nulle autre autorité. Ils ont mesuré quel degré d’obéissance était dû au gouvernement de Vichy en montrant que la réponse à la question politique provient d’un regard théologique.

Soutenir l’Ukraine est donc essentiel et doit s’inscrire dans la durée, avec une industrie de défense passant en économie de guerre. Nous devons également renforcer notre rôle au sein de l’Otan pour répondre aux menaces.
Mobiliser en Ukraine et en Russie : pratique militaire, gestion politique et impact social
Authors: Colin Lebedev Anna
Published: March 2024

Si l’Ukraine avait déjà tiré des leçons du fiasco de 2014, la Russie a été confrontée à des difficultés en septembre 2022 avec une mobilisation partielle mal conduite. La question reste posée après deux ans de guerre avec des pratiques et des questionnements très différents entre les deux pays, entre gestion démocratique pour Kiev et gestion autoritaire pour Moscou.

Le tandem franco-allemand est confronté à de nombreux défis dont la divergence de perception des enjeux stratégiques. La crise ouverte par la guerre en Ukraine a poussé Berlin à accroître son effort de défense sans forcément renforcer la coopération avec la France. Il serait pourtant nécessaire de faire davantage converger les approches afin d’affronter les nouvelles menaces.
Horthy, Piłsudski et Skoropadsky : trois militaires chefs d’État, figures de l’indépendance de leurs pays
Authors: de Kaniv Nathalie
Published: March 2024

La construction des indépendances des États d’Europe centrale a été complexe à l’issue de la Grande Guerre avec l’effondrement des empires russe, allemand et austro-hongrois. Des chefs militaires, Horthy, Piłsudski et Skoropadsky, devinrent des dirigeants politiques affirmant la souveraineté de leurs jeunes États. Leur héritage – parfois controversé – reste vivant dans la mémoire collective de l’Europe de l’Est.
Histoire militaire

Le maintien de l’ordre fut jusqu’au début du XX e une des missions de l’armée avec plus ou moins de succès. Après la Grande Guerre et notamment le 6 février 1934, le commandement fut très réticent face aux demandes des autorités politiques, maintien de l’ordre et opération militaire ne relevant pas des mêmes logiques.
À l’approche de Paris 2024, que sait-on de la gouvernance et de la performance des Jeux Olympiques ? Une critique de l’approche actuelle du CIO
Authors: Plaisance Guillaume
Published: March 2024

Face aux critiques venues tout à la fois des communautés, des acteurs publics et privés et de la recherche, le Comité International Olympique s’est engagé dans une gouvernance ouverte à ses parties prenantes et guidée par l’héritage des Jeux. En dépit de ces efforts, cette revue narrative montre que ce choix ne semble pas pertinent sur le moyen et long terme, en particulier car il est exclusif des autres dimensions de la gouvernance et de la performance des JO. Une ouverture au concept de performance globale et une approche collaborative (menant à la cohabitation du contrôle et de la qualité de la relation avec les parties prenantes) sont proposées.
Quelle recherche-action participative au service de la democratie participative a Railcoop ? Retour sur une experimentation
Authors: Ballon Justine , Chevallier Marius
Published: March 2024

Si savoir, c’est pouvoir, alors la démocratisation des méthodes de recherche pourrait se traduire par un renforcement du pouvoir d’agir des membres dans leurs organisations. Dans les Sociétés Coopératives d’Intérêt Collectif (SCIC) qui associent plusieurs parties prenantes dans leur gouvernance, c’est un défi au cœur du processus de production. Cet article propose d’explorer ce rapport entre démocratie participative et recherche-action participative (RAP) dans une coopérative à partir d’une expérimentation menée par des sociétaires (dont une chercheuse et un chercheur, qui ont écrit ce présent article), au sein de la SCIC ferroviaire Railcoop. Parmi ses 14 000 sociétaires, environ 800 sont impliqués dans 30 cercles de sociétaires. Cette étude de cas met en lumière les apports et les limites d’une RAP pour nourrir la démocratie participative d’une coopérative.
L’intelligence collective, un outil au service de l’identite professionnelle des assistants sociaux du secteur public
Authors: Le Gloahec Noëmie
Published: March 2024

Les mutations du contexte institutionnel et législatif puis l’évolution des métiers du travail social sont venus inévitablement impacter l’identité professionnelle des assistants sociaux, entrainant des conséquences à la fois individuelles (perte de sens, RPS, turn-over…) et collectives (baisse de la performance et de la qualité du service rendu…). En parallèle, l’intelligence collective apparait comme une pratique de management novatrice peu exploitée car contraignante et peu opérationnelle. Notre enquête au sein d’un service d’action sociale d’une collectivité territoriale a cherché à approfondir les contours et l’évolution de l’identité professionnelle des assistants sociaux et de mieux comprendre, grâce à une étude qualitative, l’impact des pratiques d’intelligence collective sur cette identité professionnelle. Nos résultats permettent de définir l’identité professionnelle des assistants sociaux, de relever leurs valeurs et de mieux comprendre les évolutions. L’intelligence collective se subdivise en 5 sous-thèmes, à savoir la connaissance, la co-construction, les prérequis et l’intérêt, et pour finir les freins.
Ce que la periode de Covid-19 nous a appris sur la gestion de l’Autre : un eclairage postmoderne sur management et leadership
Authors: Lacan Arnaud
Published: March 2024

La période Covid-19 a bouleversé nos modèles de RH et de management parce qu’elle a imposé le télétravail qui était jusqu’à lors peu prisé des entreprises et des managers. Elle a ainsi éclaté les équipes de collaborateurs dans des modèles hybrides de travail et cette désintégration des équipes a souvent eu comme conséquence des difficultés pour les collaborateurs à conserver le sentiment de faire équipe. L’approche postmoderne nous apporte quelques lumières sur la plus que jamais nécessité de ce lien à l’Autre en proposant le passage d’un système de valeurs dépassées à un système postmoderne beaucoup plus éclairant pour la période qui nous intéresse. Cet article propose une réflexion sur les pratiques RH et de management pour remettre la relation aux autres (l’Autre) au centre des objectifs managériaux. Nous pourrons alors dessiner un management de l’après qui se fonde sur un management de l’Autre.
Approximating reproduction numbers: a general numerical method for age-structured models
Authors: De Reggi Simone , Scarabel Francesca , Vermiglio Rossana
Published: March 2024

In this paper, we introduce a general numerical method to approximate the reproduction numbers of a large class of multi-group, age-structured, population models with a finite age span. To provide complete flexibility in the definition of the birth and transition processes, we propose an equivalent formulation for the age-integrated state within the extended space framework. Then, we discretize the birth and transition operators via pseudospectral collocation. We discuss applications to epidemic models with continuous and piecewise continuous rates, with different interpretations of the age variable (e.g., demographic age, infection age and disease age) and the transmission terms (e.g., horizontal and vertical transmission). The tests illustrate that the method can compute different reproduction numbers, including the basic and type reproduction numbers as special cases.
Restoration and integration of the Huang Family Garden within the contemporary urban fabric of Shanghai
Authors: Yan Aibin , Zheng Dinghan
Published: March 2024

In the backdrop of Shanghai's century-long urbanization and modernization, traditional private gardens have undergone a profound transformation influenced by Western lifestyles, concepts, and garden characteristics. This transformation, marked by an East-meets-West fusion, deviates from the conventions of traditional gardens. In this study, we delved into the historical evolution of these private gardens into urban parks against the canvas of evolving urban life and point out that the construction of the city-park interaction mechanism hinges on how to consolidate transformation motives and empower urban space. Focusing on the case study of the Huang Family Garden owned by the Qing Gang tycoon Gold Wing and employing a spatial culture research perspective, we illuminated how the metamorphosis of a private garden into an urban park catalyzed the development of an urban area and scrutinized the spatial transformation of the Huang Family Garden amid Shanghai's urban modernization. Furthermore, our results revealed the inherent public nature of the Huang Family Garden's evolving garden space, along with the continuous manifestation and strengthening of this characteristic through successive urban renovations. The results emphasized the role of gardens in urban resilience and sustainability, highlighting the contribution of garden spaces as public domains. The features exhibited during the transformation of private gardens into urban parks create conditions for enhancing urban resilience, while providing insights into the significance of understanding garden traits in the evolution of cities.
An analysis of SPEEK as a
suitable alternative for Nafion
in a proton electrolyte
membrane in PEM fuel cells
Authors: Yasin Ihsaan
Published: March 2024

The Proton-Exchange Membrane Fuel Cell (PEMFC) has the potential to enable hydrogen worldwide as a clean energy storage medium. However, before it can be implemented globally, the PEMFC needs to be optimized with innovative technology to maximize its efficiency. This investigation will analyze the methods in which the efficiency can be optimized through a different polymer material that can be used as solid polymer electrolyte membrane in the PEM fuel cell, comparing Nafion with Sulfonated Poly (ether ether ketone) as the most effective electrolyte membrane by efficiency.
An Efficient NoSQL-Based Storage Schema for Large-Scale Time Series Data
Authors: Ma Ruizhe , Zhou Weiwei , Ma Zongmin
Published: March 2024

In IoT (internet of things), most data from the connected devices change with time and have sampling intervals, which are called time-series data. It is challenging to design a time series storage model that can write massive time-series data in a short time and can query and analyze the persistent time-series data for a long time. This paper constructs the RHTSDB (Redis-HBase Time Series Database) storage model based on Redis and HBase. RHTSDB uses the memory database Redis (Remote Dictionary Server) to cache massive time-series data, providing efficient data storage and query functions. HBase is used in RHTSDB for long-term storage of time-series data to realize their persistence. The paper designs a cold and hot separation mechanism for time-series data, where the infrequently accessed cold data are stored in HBase, and the frequently accessed and latest data are stored in Redis. Experiments verify that RHTSDB has apparent advantages over Apache IoTDB and HBase in data intake and query efficiency.
Politics of Health Care Politics: A Call to Action
Authors: O’Rourke Nancy , Outly Amanda
Published: March 2024

Nursing has been perceived as an apolitical profession. Although some advancements in legislation and political engagement for nursing have occurred, the perception remains; it is considered to be a relatively silent profession in the political and policy arenas. Authors, when trying to describe this phenomenon, have raised questions about whether the nursing profession is political. In addition, the motivation for participation and advocacy, as well as the barriers to these activities, have limited investigation, making it difficult to understand the real reasons behind nursing’s political and policy immobility. The purpose of this article is to familiarize readers with politics, policy, and advocacy; levels of state and federal government; and the lawmaking process in different states. The goal is to offer information and identify factors that increase confidence and efficacy when engaging with the political system.
LACE and the APRN Consensus Model: Implications for Advancing Nursing Practice
Authors: Davis Wesley , Stanley Joan , Buck Michelle , Walters Elizabeth , DeGarmo Sean
Published: March 2024

Understanding the historical context and contemporary trends in advanced practice registered nurse (APRN) education and regulation is pivotal for effective professional advocacy. Until the release of the APRN Consensus Model in 2008, a uniform model for APRN regulation was lacking. Adopting the model’s recommendations has implications for APRNs beyond licensure and regulation, including full practice authority, license portability, and patient access to APRN-led care. A comprehensive understanding of APRN education and regulation empowers nurses, APRNs, and stakeholders to drive the profession forward through informed advocacy.
