Posturas del paradigma socio-crítico como aportes a la educación y gestión educativa en Colombia
Authors: Álvarez Giraldo Neidy Bibiana , Cardozo Cruz Jonatan Julian , Mejía Guarín Sandra Milena
Published: January 2024

Este ensayo de investigación se presenta como aporte de los autores en el marco de la filosofía de la ciencia, con el propósito de reflexionar sobre el llamado de múltiples comunidades educativas colombianas a una genuina y determinante revolución científica en educación. Los autores describen los enfoques y tendencias de investigación, filosofía y ciencia, de grandes representantes que realizaron aportes teóricos significativos mediante el paradigma socio-crítico en general y luego en Latinoamérica. Seguidamente, se caracterizan aportes específicos a la educación y gestión educativa, finalizando con las posturas de un proponente influyente en Colombia. El paradigma socio-crítico pretende desde la teoría crítica, la liberación en cuanto al pensamiento y emancipación de los actores educativos en los contextos que estos vivencian, a través de la razón comunicativa y argumentación de las posturas que conlleven a la transformación social de su entorno mediante el intercambio de intersubjetividades que redunden en la reestructuración del sistema educativo. Desde las posturas del paradigma socio-crítico expuestas, los autores concluyen el artículo, con el capítulo que presenta dichos aportes frente a la guía 34 (Guía para el mejoramiento institucional de la autoevaluación al plan de mejoramiento, establecida por el Ministerio de Educación colombiano) como insumo para concretar procesos de mejoramiento continuo, ajustados a la realidad institucional de la gestión educativa en Colombia.
La oportunidad inesperada para el campo educativo surgida de la pandemia covid-19. Una mirada esperanzadora para el porvenir
Authors: Márquez Peñaranda César Gerardo , Villavicencio Galindo Judith Margarita , Muñoz Blanco Leidy Carolina
Published: January 2024

El presente artículo pretende rastrear los principales retos que afrontaron los sistemas educativos durante el retorno gradual y progresivo al estudio presencial luego de dos años de estudio desde casa motivado por la pandemia COVID-19. La revisión se fundamenta en el periodo trascurrido desde marzo de 2020, correspondiente al inicio del confinamiento derivado de la pandemia COVID-19, hasta el actual junio de 2022 que es el tiempo en que se elaboró el presente documento. Fueron objeto de revisión 45 artículos alojados en Google Scholar, Scopus, Redalyc y Scielo publicados en inglés, español y portugués cuya relación con el tema propuesto fue determinada con expresiones clave: “Post-pandemic education”, “Education after COVID-19”, “Challenges of COVID-19 in education”. La elección de los artículos que dieron forma a la discusión está basada en una matriz de datos elaborada a partir de los artículos revisados y para su producción se tuvo en cuenta los rasgos fundamentales del proceso previo al retorno a clases presenciales como fueron la conectividad, la socialización y la salud mental. Los resultados inducen a pensar que los sistemas educativos, luego de lo más crudo de la pandemia, tienen ante sí la oportunidad de revisar sus postulados esenciales y generar procesos adaptativos con el potencial de producir una revolución en la enseñanza en centros educativos. El análisis y revisión busca ofrecer una mirada alternativa al ya conocido discurso desesperanzador que da por sentado que todos los esfuerzos por educar de forma remota durante al confinamiento fueron infructuosos y que el sufrir esta crisis no nos deja ninguna lección.

Aprendizaje significativo en la enseñanza de la economía
Authors: Avilés Ramírez Hernando Manuel
Published: January 2024

Este ensayo argumentativo se fundamenta en las reflexiones teórica que han hecho otros autores a cerca del aprendizaje significativo, razonando al mismo tiempo como podría mejorar la enseñanza de la economía a la luz de la teoría del aprendizaje significativo en la visión clásica de David Ausubel; así, como también los aportes de Moreira, entre otros. En la práctica docente la mayoría de estrategias didácticas continúa promoviendo mucho más el aprendizaje mecánico, puramente memorístico, que el significativo. Razón por la cual, se detalla que es el aprendizaje significativo, aspectos a tener en cuenta, argumentando que para lograr un aprendizaje significativo en economía hay que partir de la realidad económica, del papel facilitador del profesor en la programación del contenido, al seleccionar el potencial material didáctico que se ajuste a las estructuras cognitivas del alumno. En el razonamiento, se abordan algunas realidades económicas como el mercado con monopolios, oligopolios, las crisis financieras y la forma como deben presentarse al estudiante, para que él pueda visualizar como lo que aprende le sirve para la vida, de tal forma que comprenda, analice, reflexione, logre un aprendizaje significativo crítico y participe activamente en la sociedad; Logros que pueden darse con el acompañamiento y orientación docente, el trabajo en equipo y apoyo de las nuevas herramientas digitales.

Published: January 2024

The Internet of Things (IoT) brings new products to everyone to improve daily life. Concurrently other emerging technologies, including Big Data, Cloud Services, and surveillance, can participate through these technological advances. This research work explores the synergies among four systems to identify their shared functionalities and integrate them to create useful potential applications. Despite the limitations of the smart city concept, researchers would seek innovative methods to collect and process sensor information within an IoT-enabled smart building. A cornerstone of the proposed system is the utilization of cloud services as the foundational technology for a schema management platform. This platform efficiently gathers data generated by sensors within smart industrial units. Leveraging the capabilities of IoT technology, the data can be remotely managed and accessed using mobile devices with network connectivity. The proposed work addresses the challenges related with the smart city perception and supports for revolutionary approaches in the collection and manipulation of IoT Sensor data. By doing so, it imagines the creation of green, smart schemes that contribute to sustainable urban development.
Do the Structural Funds in innovation influence the growth of companies? Analysis through the ERDF-Innterconecta programme in Andalusia differentiating by business size and role in the projects
Authors: Sande Veiga Diego
Published: January 2024

As a Convergence Objective Autonomous Community of the European Union, Andalusia was a beneficiary of the significant volume of European resources for regional innovation mobilised by the 2007-2013 Technological Fund and the 2014-2020 Smart Growth programme. The Andalusian productive fabric is mostly made up of Small and Medium-sized Enterprises (SMEs). For this reason, we evaluate the impact of the ERDF-Innterconecta programme financed through the previous operational programmes on the main indicators of business growth. The proposed analysis seeks to identify whether there has been an impact for Andalusian companies that have participated in the subsidised projects on three indicators (income, GVA, number of employees), further differentiating these companies by size, participation in innovation and role taken in the funded projects. This impact varies according to the characteristics of the companies.

Published: January 2024

El uso de cocientes de localización para la estimación de tablas input output regionales se ha considerado como una herramienta útil y eﬁciente en la estimación de multiplicadores de producción intrarregionales. A partir de esta herramienta, se han desarrollado procedimientos más complejos que estiman simultáneamente coeﬁcientes interregionales. En este trabajo se evalúa la capacidad de esta metodología ampliada (que denominamos metodología Jahn) para la obtención de multiplicadores tanto intrarregionales como interregionales para el caso español, estimando a partir de la Tabla Input-Output (TIO)de España 2015 las correspondientes a las de las regiones españolas de Andalucía; País Vasco y Navarra para el mismo año y para las que disponemos de sus resultados mediante encuesta. Para contrastar su ﬁabilidad, eﬁciencia y precision, los resultados obtenidos con el procedimiento anterior se comparan con otras metodologías ampliamente utilizadas por su reconocida eﬁciencia, las metodologías GRAS y Gravity-RAS.
The Strength and Variability of the Helium 10830 Å Triplet in Young Stars, with Implications for Exosphere Detection
Authors: Krolikowski Daniel M. , Kraus Adam L. , Tofflemire Benjamin M. , Morley Caroline V. , Mann Andrew W. , Vanderburg Andrew
Published: January 2024

Young exoplanets trace planetary evolution, in particular the atmospheric mass loss that is most dynamic in youth. However, the high activity level of young stars can mask or mimic the spectroscopic signals of atmospheric mass loss. This includes the activity-sensitive He 10830 Å triplet, which is an increasingly important exospheric probe. To characterize the He-10830 triplet at young ages, we present time-series NIR spectra for young transiting planet hosts taken with the Habitable-zone Planet Finder. The He-10830 absorption strength is similar across our sample, except at the fastest and slowest rotations, indicating that young chromospheres are dense and populate metastable helium via collisions. Photoionization and recombination by coronal radiation only dominates metastable helium population at the active and inactive extremes. Volatile stellar activity, such as flares and changing surface features, drives variability in the He-10830 triplet. Variability is largest at the youngest ages before decreasing to ≲5–10 mÅ (or 3%) at ages above 300 Myr, with six of eight stars in this age range agreeing with there being no intrinsic variability. He-10830 triplet variability is smallest and age-independent at the shortest timescales. Intrinsic stellar variability should not preclude detection of young exospheres, except at the youngest ages. We recommend out-of-transit comparison observations taken directly surrounding transit and observation of multiple transits to minimize activity’s effect. Regardless, caution is necessary when interpreting transit observations in the context of stellar activity, as many scenarios can lead to enhanced stellar variability even on timescales of an hour.
The Carbon-to-oxygen Ratio in Cool Brown Dwarfs and Giant Exoplanets. I. The Benchmark Late-T Dwarfs GJ 570D, HD 3651B, and Ross 458C
Authors: Phillips Mark W. , Liu Michael C. , Zhang Zhoujian
Published: January 2024

Measurements of the C/O ratio in brown dwarfs are lacking, in part due to past models adopting solar C/O only. We have expanded the ATMO 2020 atmosphere model grid to include nonsolar metallicities and C/O ratios in the T dwarf regime. We change the C/O ratio by altering either the carbon or oxygen elemental abundances, and we find that nonsolar abundances of these elements can be distinguished based on the shapes of the H and K bands. We compare these new models with medium-resolution (R ≈ 1700), near-infrared (0.8–2.4 μm) Gemini Near-Infrared Spectrograph (GNIRS) spectra of three benchmark late-T dwarfs, GJ 570D, HD 3651B, and Ross 458C. We find solar C/O ratios and best-fitting parameters (T

, Z) broadly consistent with other analyses in the literature based on low-resolution (R ∼ 100) data. The model-data discrepancies in the near-infrared spectra are consistent across all three objects. These discrepancies are alleviated when fitting the Y, J, H, and K bands individually, but the resulting best-fit parameters are inconsistent and disagree with the results from the full spectrum. By examining the model atmosphere properties we find this is due to the interplay of gravity and metallicity on H2–H2 collisionally induced absorption. We therefore conclude that there are no significant issues with the molecular opacity tables used in the models at this spectral resolution. Instead, deficiencies are more likely to lie in the model assumptions regarding the thermal structures. Finally, we find a discrepancy between the GNIRS, SpeX, and other near-infrared spectra in the literature of Ross 458C, indicating potential spectroscopic variability.
Electromagnetic Counterparts Powered by Kicked Remnants of Black Hole Binary Mergers in AGN Disks
Authors: Chen Ken , Dai Zi-Gao
Published: January 2024

The disk of an active galactic nucleus (AGN) is widely regarded as a prominent formation channel of binary black hole (BBH) mergers that can be detected through gravitational waves (GWs). Besides, the presence of dense environmental gas offers the potential for an embedded BBH merger to produce electromagnetic (EM) counterparts. In this paper, we investigate EM emission powered by the kicked remnant of a BBH merger occurring within the AGN disk. The remnant BH will launch a jet via the accretion of a magnetized medium as it traverses the disk. The resulting jet will decelerate and dissipate energy into a lateral cocoon as it propagates. We explore three radiation mechanisms of the jet–cocoon system—jet breakout emission, disk cocoon cooling emission, and jet cocoon cooling emission—and find that the jet cocoon cooling emission is likely to be detected in its own frequency bands. We predict a soft X-ray transient, lasting for O(103) s, to serve as an EM counterpart, of which the time delay O(10) days after the GW trigger contributes to follow-up observations. Consequently, BBH mergers in the AGN disk represent a novel multimessenger source. In the future, enhanced precision in measuring and localizing GWs, coupled with diligent searches for such associated EM signals, will effectively validate or restrict the origin of BBH mergers in the AGN disk.
Origin and Composition of the Galactic Diffuse X-Ray Emission Spectra by Unresolved X-Ray Sources
Authors: Koyama Katsuji , Nobukawa Masayoshi
Published: January 2024

Galactic diffuse X-ray emission (GDXE) can be spatially segmented into Galactic center X-ray emission (GCXE), Galactic ridge X-ray emission (GRXE), and Galactic bulge X-ray emission (GBXE). The X-ray spectra of GDXE are expressed by the assembly of compact X-ray sources, which are either white dwarfs (WDs) or X-ray active stars consisting of binaries with late-type stars. WDs have either a strong magnetic field or a weak magnetic field. WDs and X-ray active stars are collectively called compact X-ray stars. However, spectral fittings by the assembly of all compact X-ray stars for GCXE, GRXE, and GBXE are rejected, leaving significant excess near the energies of the Kα, Heα, and Lyα lines. These excesses are found in the collisional ionization equilibrium (CIE) plasma. Thus, the spectra of GRXE and GBXE are improved by adding CIE supernova remnants (SNRs). However, the GCXE spectrum is still unacceptable, with significant data excess due to radiative recombination emission (recombining plasma (RP)). The GCXE fit is then significantly improved by adding aged RP-SNRs. Aged RP-SNRs are made by a past big flare of Sgr A* emitting either hard X-rays or low-energy cosmic rays. The big flares may excite Fe and Ni atoms in cold diffuse gas (cold matter (CM)) and emit fluorescent X-ray lines. The CIE-SNRs, RP-SNRs, and CM are called diffuse X-ray sources. This paper presents the spectral fits by the assembly of all the compact and diffuse X-ray sources together with high-quality spectra and a combined fit among all the GDXE of GCXE, GRXE, and GBXE. This provides the first scenario to quantitatively and comprehensively predict the origin of the GDXE spectra.
Variations of Interstellar Gas-to-dust Ratios at High Galactic Latitudes
Authors: Shull J. Michael , Panopoulou Georgia V.
Published: January 2024

Interstellar dust at high Galactic latitudes can influence astronomical foreground subtraction, produce diffuse scattered light, and soften the UV spectra of quasars. In a sample of 94 sight lines toward quasars at high latitude and low extinction, we evaluate the interstellar “gas-to-dust ratio” N
H/E(B − V), using hydrogen column densities (H i and H2) and far-IR (FIR) estimates of dust reddening. In the Galactic plane, this ratio is 6.0 ± 0.2 (in units of 1021 cm−2 mag−1). On average, recent Planck estimates of E(B − V) in low-reddening sight lines are 12% higher than those from Schlafly & Finkbeiner, and N
H I exhibits significant variations when measured at different radio telescopes. In a sample of 51 quasars with measurements of both H i and H2 and 0.01 ≤ E(B − V) ≲ 0.1, we find mean ratios 10.3 ± 0.4 (gas at all velocities) and 9.2 ± 0.3 (low-velocity only) using Planck E(B − V) data. High-latitude H2 fractions are generally small (2%–3% on average), although nine of 39 sight lines at ∣b∣ ≥ 40° have f
H2 of 1%–17%. Because FIR-inferred E(B − V) is sensitive to modeled dust temperature T

d
and emissivity index β, gas-to-dust ratios have large, asymmetric errors at low E(B − V). The ratios are elevated in sight lines with high-velocity clouds, which contribute N
H but little reddening. In Complex C, the ratio decreases by 40% when high-velocity gas is excluded. Decreases in dust content are expected in low-metallicity gas above the Galactic plane, resulting from grain destruction in shocks, settling to the disk, and thermal sputtering in hot halo gas.
Mapping a Lower Limit on the Mass Fraction of the Cold Neutral Medium Using Fourier-transformed H i 21 cm Emission Line Spectra: Application to the DRAO Deep Field from DHIGLS and the HI4PI Survey

Tested on a numerical simulation of thermally bi-stable turbulence, the lower limit from this method has a strong linear correlation with the “true” cold gas mass fraction from the simulation for a relatively low cold gas mass fraction. At a higher mass fraction, our lower limit is lower than the “true” value, because of a combination of interference and opacity effects. Comparison with absorption surveys shows a similar behavior, with a departure from linear correlation at N
H I ≳ 3–5 × 1020 cm−2. Application to the DRAO Deep Field from DHIGLS reveals a complex network of cold filaments in the Spider, an important structural property of the thermal condensation of the H i gas. Application to the HI4PI survey in the velocity range −90 < v < 90 km s−1 produces a full sky map of a lower limit on the mass fraction of the cold neutral medium at 16.′2 resolution. Our new method has the ability to extract a lower limit on the cold gas mass fraction for massive amounts of emission line data alone with low computing time and memory, pointing the way to new approaches suitable for the new generation of radio interferometers.
Filament Eruption from Active Region 13283 Leading to a Fast Halo-CME and an Intense Geomagnetic Storm on 2023 April 23
Authors: Vemareddy P.
Published: January 2024

Using multi-instrument and multiwavelength observations, we studied a coronal mass ejection (CME) that led to an intense geomagnetic storm on 2023 April 23. The eruption occurred on April 21 in solar active region (AR) 13283 near the disk center. The AR was in its decay stage, with fragmented polarities and a preexisting long filament channel a few days before the eruption. The study of the magnetic field evolution suggests that the flux rope (filament) was built up by monotonous helicity accumulation over several days, and furthermore, converging and canceling fluxes led to a change in helicity injection, resulting in an unstable nature of the magnetic flux rope (MFR) and its further eruption. Importantly, the CME morphology revealed that the MFR apex underwent a rotation of up to 56° in clockwise direction owing to its positive helicity. The CME decelerates in the field of view (FOV) of the Large Angle Spectrometric Coronagraph and has a plane-of-sky velocity of 1226 km s−1 at 20 R
⊙. In the FOV of the Heliospheric Imager, the lateral expansion of the CME is tracked better than the earthward motion. This implies that the arrival time is difficult to assess. The in situ arrival of the interplanetary CME shock was at 07:30 UT on April 23, and a geomagnetic storm commenced at 08:30 UT. The flux rope fitting to the in situ magnetic field observations reveals that the magnetic cloud flux rope orientation is consistent with its near-Sun orientation, which has a strong negative Bz-component. The analysis of this study indicates that the near-Sun rotation of the filament during its eruption to the CME is the key to the negative Bz-component and consequently the intense geomagnetic storm.

Published: January 2024

In the north-eastern Atlantic and Mediterranean Sea, the pleurobranchid genus Pleurobranchaea Leue, 1813 is represented by two species, Pleurobranchaea meckeli (Blainville, 1825) and Pleurobranchaea morosa (Bergh, 1892). The former is a well-known species distributed from northern Spain to Senegal and the Mediterranean Sea, while the second is a poorly-described species. In this contribution, species delimitation analyses (ABGD and COI/16S p-distances) identified a third undescribed Pleurobranchaea species from samples collected in south-western UK waters and the Gulf of Cadiz (SW Spain). This new species, Pleurobranchaea britannicasp. nov., is also supported by several morphological synapomorphies. The British specimens constitute the first occurrence of the genus Pleurobranchaea in UK waters.

Authors: Hashemi Javaheri Zeinab , Sabermoghaddam Ali Akbar , Abrishami Mojtaba , Kiarudi Mohammad Yaser , Motamed Shariati Mehrdad
Published: January 2024

Purpose:

To evaluate the short-term effects of inferior oblique myectomy on the retinal neurovasculature, choroidal thickness, and choroidal vascularity index at the macula.

Methods:

Patients older than 5 years who were candidates for inferior oblique muscle myectomy surgery participated in the study. Patients with any systemic or ocular disease that could affect the macular neurovasculature were not included in the study. After recording demographic data, including age and gender, and conducting a complete ophthalmic examination, macular optical coherence tomography (OCT), enhanced depth imaging OCT, and OCT angiography imaging (AngioVue software (V.2017.1.0.151; Optovue, Inc) were performed before (1 day to 1 week) and in the specific time intervals (1 week, 1 month, and 3 months) after the surgery for all participants.

Results:

Eighteen patients (13 male and 5 female) who underwent inferior oblique muscle myectomy, with a mean ± standard deviation age of 24.22 ± 18.14 years, were included in this study. The baseline mean ± standard deviation of subfoveal choroidal luminal area and subfoveal total choroidal area were 0.390 ± 0.03 and 0.539 ± 0.04 mm
2
, respectively. The changing pattern of the subfoveal choroidal vascularity index and subfoveal choroidal luminal area was statistically significant (

Conclusions:

Inferior oblique myectomy can lead to changes in choroid hemodynamics in the short term. However, these changes seem to be temporary.

Machine Learning-Based Classification of Small-Sized Wetlands Using Sentinel-2 Images
Authors: Salas Eric Ariel L. , Kumaran Sakthi Subburayalu , Bennett Robert , Willis Leeoria P. , Mitchell Kayla
Published: January 2024

Wetlands are invaluable ecosystems, offering essential services such as carbon sequestration, water purification, flood control and habitat for countless aquatic species. However, these critical environments are under increasing threat from factors like industrialization and agricultural expansion. In this research, we focused on small-sized wetlands, typically less than 10 acres in size, due to their unique ecological roles and groundwater recharge contributions. To effectively protect and manage these wetlands, precise mapping and monitoring are essential. To achieve this, we exploited the capabilities of Sentinel-2 imagery and employ a range of machine learning algorithms, including Random Forest (RF), Classification and Regression Tree (CART), Gradient Tree Boost (GTB), Naive Bayes (NB), k-nearest neighbors (KNN) and Support Vector Machine (SVM). Our evaluation used variables, such as spectral bands, indices and image texture. We also utilized Google Earth Engine (GEE) for streamlined data processing and visualization. We found that Random Forest (RF) and Gradient Tree Boost (GTB) outperformed other classifiers according to the performance evaluation. The Normalized Difference Water Index (NDWI) came out to be one of the important predictors in mapping wetlands. By exploring the synergistic potential of these algorithms, we aim to address existing gaps and develop an optimized approach for accurate small-sized wetland mapping. Our findings will be useful in understanding the value of small wetlands and their conservation in the face of environmental challenges. They will also lay the framework for future wetland research and practical uses.
Local existence of solutions to the 2D MHD boundary layer equations without monotonicity in Sobolev space
Authors: Dong Xiaolei
Published: January 2024

In this work, we investigated the local existence of the solutions to the 2D magnetohy-drodynamic (MHD) boundary layer equations on the half plane by energy methods in weighted Sobolev space. Compared to the existence of solutions to the classical Prandtl equations where the monotonicity condition of the tangential velocity plays an important role, we used the initial tangential magnetic field with a lower bound $ \delta > 0 $ instead of the monotonicity condition of the tangential velocity.

Essai sur l’enseignement de géographie sociale
Authors: Hérin Robert
Published: January 2024

À partir des années 1970-1980, la didactique de la géographie a suscité en France de nombreuses recherches. C’est à partir de ces mêmes années que la géographie sociale s’est affirmée comme courant de pensée et manière nouvelle d’être géographe, mais sans que soit développée une réflexion collective sur son enseignement. Dans cet essai, on se propose de définir des objectifs pour l’enseignement de la géographie sociale et l’on s’interroge sur les possibles spécificités des méthodes de cet enseignement. En fait c’est plus par le choix des thèmes, le déroulement de la démarche pédagogique et la volonté de contribuer à former l’esprit critique et les comportements civiques des élèves que peut se distinguer l’enseignement de la géographie sociale.

La périurbanisation est souvent appréciée en France comme un avancement des espaces urbanisés sur des espaces agricoles ou boisés avec pour objet la maison individuelle. Ce processus doit cependant beaucoup aux politiques du logement qui ont, surtout depuis 1977, favorisé l’accession à la propriété et la démocratisation de la voiture individuelle. Toutefois, à cette dynamique morphologique se surajoute une dimension sociale puisque la progression de ces espaces traduit également un processus de différenciation sociale et fonctionnelle induisant une mobilité, elle aussi individuelle, nécessitant le développement toujours plus conséquent d’infrastructures. Ces espaces se sont aujourd’hui, pour une partie d’entre eux, autonomisés. Dans le même temps, ce processus se poursuit par l’étalement de l’urbain et l’émiettement, incorporant toujours par métissage de nouveaux espaces ruraux. Si le peuplement de ces espaces périurbains est le fait d’une large couche moyenne, il n’en est pas moins gouverné par des logiques de fragmentation et de classement dessinant une marqueterie sociale en lien avec l’histoire et la géographie de chaque aire urbaine. Il participe également à la recomposition des ségrégations et des polarisations sociales à toutes les échelles – de l’aire urbaine au lotissement en passant par la commune. Mais ces espaces périurbains sont aussi devenus des lieux de résidence de couches sociales plus modestes. Pour ces familles, rencontrées dans un « envers du décor » périurbain, l’accession à la propriété peut parfois devenir un piège. Pour elles, le décalage est en tout cas important entre des aspirations proches de celles de la « classe moyenne » et les difficultés à les réaliser. Les espaces périurbains, même les plus dévalorisés, semblent animés d’une capacité de résilience et d’innovation qui, si elle nuance les discours d’opprobres et de non-durabilité à leur égard, pose des questions sur les logiques d’organisation à l’œuvre.
Conclusion : comment pourrions-nous ne pas nous dire géographes sociaux ?
Authors: Cerreti Claudio
Published: January 2024

Cette intervention n’a pas pour but de conclure la comparaison franco-italienne recueillie dans ce volume, mais seulement d’exposer quelques considérations et pistes de réflexion a posteriori. Avant tout, l’histoire différente de la géographie sociale en France et en Italie. En Italie, pendant longtemps, l’appellation n’a presque pas eu de succès : les thèmes et les objectifs analogues à ceux pratiqués par la géographie sociale française étaient traités au sein de la géographie humaine et de ses composantes. Cette absence pourrait être le résultat d’un contrôle plus strict exercé par la communauté des géographes italiens. La géographie sociale française, qui commence à être pratiquée à partir des années 1970 parallèlement à la géographie humaine classique, pourrait toutefois trouver un équivalent dans le groupe italien de « Géographie démocratique ». Le caractère épistémologique fondamental de la géographie sociale, en d’autres termes, la priorité du social sur le spatial, risque désormais de ne plus être un caractère spécifique, dans la mesure où cette priorité est insérée dans tous les discours géographiques contemporains. Malgré cela, une géographie sociale semble conserver une raison précise d’exister, et quelques acquisitions ou propositions récentes lui confèrent des perspectives substantielles, tels l’emploi du concept de territoire comme instrument d’analyse et la référence aux dynamiques sociétales. Enfin, de la géographie sociale française vient un exemple d’« engagement » du géographe en tant qu’intellectuel, qui confère un sens précis et incontournable à son activité de recherche.
Brand Evangelism Within the Framework of Digital Labor
Authors: Çelik Fikriye
Published: January 2024

Renewed labor practices have linked immaterial labor to material labor processes. The creative power and activity connection of social media users, who are considered today's networked workers, as one of the stages of digital labor is one of the most important examples of this situation. Considering the appearance of labor in the new world, it is understood that brand evangelism is one of the forms of labor exploitation of contemporary capitalism. In this context, in the study, brand evangelism seen in Instagram was discussed within the framework of digital labor. The sample of the research consists of three Instagram user accounts with high followers who produce paid content in exchange for brand collaboration or advertising on social media. Forty images included in the research were subjected to content analysis. At the end of the research, it was concluded that Instagram stands out as the application area of brand evangelism and pointed out that the free labor culture that has become widespread in the digital environment covers labor exploitation.

Published: January 2024

Human resource management and leadership styles are one of the key strategic issues for small and medium size enterprises. With the growing importance of SMEs all over the world, many small firms fail in their formative stage of life cycle. Academic research on SMEs in this context is scarce. In addition to scarcity of research, researchers overlooked the specific characteristics of small firms. In this chapter, the authors have provided a theoretical rationale for the differences in specific characteristics of SMEs. They have established the arguments that conducting the research in small firms on the same grounds as large firms leads to unreliable and hazy results. They have proposed that innovative research techniques and instruments must be established to get the true picture of human resource management techniques and leadership styles in SMEs.

Objective:

To explore the impact of Ficus carica fruit aqueous extract on fertility parameters in streptozotocin (STZ)-induced male rats.

Methods:

Twenty-four male Sprague-Dawley rats were divided into four different groups. All groups except a normal control group were induced with 50 mg/kg of streptozotocin (STZ) intravenously to induce diabetes. A positive control group was treated with an antidiabetic drug, metformin (500 mg/kg) whereas a negative control group remained untreated throughout the experiment. Meanwhile, another diabetic rat group received treatment with 400 mg/kg of aqueous Ficus carica fruit extract. Rats in the treatment group were administered Ficus carica fruit aqueous extract daily through force-feeding via oral gavage for a 21-day period. Assessments included the sperm quality (count, motility and morphology), histology of the testes, serum testosterone and fasting blood glucose (FBG) level.

Results:

The FBG level of the Ficus carica-treated rats exhibited a significant decrease compared to the negative control group (P<0.05). Sperm quality analysis also indicated that the aqueous Ficus carica extract had significant positive effects on sperm count and motility (P<0.05). The histology of the testes in Ficus carica- treated rats revealed an improved cell arrangement in the germinal cell layer. Furthermore, serum testosterone level showed an increment in the Ficus carica treatment group in comparison to the negative control group.

Conclusions:

Our findings provide compelling evidence for the pro-fertility and anti-hyperglycemic properties of aqueous Ficus carica fruit extract in diabetic-induced male rats.
