Authors:   Federal Research Center “A.O. Kovalevsky Institute of Biology of the Southern Seas of RAS” (FRC IBSS), Kopiy V. G.
Published: April 2024

This work is based on the data collected during the benthic survey of soft sediments in the coastal area of the of Lake Donuzlav conducted in August, 2020. The current status of the species composition of polychaetes in Lake Donuzlav was investigated. The samples were collected using a manually operated grab sampler with a capture area of 0.04 m2 at the depths from 1 to 8 m. The following indicators were used to describe the quantitative development of benthos: abundance, biomass, occurrence, density index, and Czekanowski-Sørensen index. A total of 31 species of polychaetes have been found. The average values of polychaetes abundance and biomass in the investigated area were 239±51 ind./m2 and 1.537± 0.599 g/m2, respectively. The main contribution to the total abundance is made by Spio decorata , and to the total biomass by Lagis neapolitana. The largest number of species and the highest abundance were recorded at the depths of 1.1-2 m. The largest biomass was recorded at the depths of 6.1-7 m. The ranked series according to the density index is headed by L. neapolitana , Glycera tridactyla , and S. decorata . The trophic structure of polychaetes is represented by poly-, phyto-, detritophages, carnivores, and the animals, the food spectrum of which has not been studied. The most widely represented group is carnivores; it comprises 10 species of polychaetes. The least number of species (1) was recorded for phytophages. Over 1990-2020, 73 species of polychaetes were identified; they belonged to 29 families and 56 genera.

Currently, there is an ongoing process of development of the next-generation pesticides, which use for the purposes of agriculture has negative implications for the environment. Their hazard potential is attributable to two factors: high biological activity and their application method involving their dispersion in the environment. It necessitates the investigation of the effect of pesticides on aquatic organisms, which includes changes in their habitat, disruptions of their vital functions, especially at the early stages of their ontogeny, accumulation in their tissues, and movement along the trophic chain. Toxicological assessment of the fungicide Cayunis, EC effect has been conducted on the aquatic organisms of various taxonomic groups: microalgae (Scenedesmus guadricauda (Turpin) Brébisson, 1835), macrophytes (Elodea canadensis Michaux, 1803), molluscs ( Planorbarius corneus (Linnaeus, 1758)), embryos and fry of the round goby (Neogobius melanostomus (Pallas, 1814)). Over the course of the experiment, the conditions for intoxication were identified, and the toxicometric characteristics of the aquatic organisms belonging to various trophic levels were estimated. Using an experimental approach, the threshold and no observed effect concentrations of the preparative form of Cayunis, EC pesticide have been identified for each test subject. This study made it possible to compare the sensitivity of each investigated test subject to the fungicide. Among the studied test subjects, round goby fry has proved to be the most sensitive to the effect of Cayunis, EC fungicide.

Based on the available data for the 2021/2022 fishing season, the ecological structure and fishing biological parameters of the European anchovy (E. encrasicolus L., 1758), wintering in the coastal waters of Abkhazia, have been analyzed. This paper presents materials that make it possible to analyze the dynamic parameters of the Azov and Black Sea stocks of the European anchovy aggregating off the coast of Abkhazia in the winter season. A comparative analysis of the main biometric parameters has been carried out. For data analysis, well-established ichthyological methods have been used. The available data on the European anchovy (both Black Sea and Azov Sea forms) caught during the investigated period characterize the dynamics of the length-age catch composition and are indicative of its intra-annual fishing patterns. Changes in the population characteristics present in the catch composition as compared with the previous years have been identified. The absolute catch values and their fluctuations are presented by the month. Analysis of the available material has indicated the main dynamic changes that characterize the wintering anchovy population as stable with a tendency for its total biomass development on a moderate level, which is not conducive for increasing the fishing effort in the next 1-2 years.

In 2019-2022, the Black Sea anchovy (Engraulis encrasicolus ponticus Alexandrov, 1927) was wintering off the western and southern coasts of Crimea, where it was subjected to heavy exploitation by the Russian fishers. The conditions resulting in the active autumn migration of the Black Sea anchovy into Crimean waters are of great scientific and practical concern. This study examines the course of the Black Sea anchovy fishing and the oceanographic conditions for its entry, migration and wintering near the southern coast of the peninsula in November and December 2021. The daily data from the FSBI “Centre of Fishery Monitoring and Communications” have been used, as well as the satellite imagery data sets of the sea surface heights and temperatures from the Copernicus Marine Service information system website. Altimetry data were used in the grid nodes with a resolution of 0.125 degrees, and temperature data were used in the grid nodes with a resolution of 0.05 degrees. Relocation of the Black Sea anchovy to Crimea in mid-November was caused by strengthening of the southeastern currents in the waters to the west of the peninsula, associated with the northern position of the Sevastopol Anticyclonic Vortex, as well as with relatively high sea surface temperatures beyond the shelf zone. In contrast to 2019 and 2020, in November and December 2021, an intense thermodynamic frontal zone of the main Black Sea current was located 15-30 miles offshore to the south of Crimea, which became a natural barrier to further migration of the Black Sea anchovy southwards and determined its distribution on the southern shelf of the Crimean Peninsula. The Black Sea anchovy fishing season in 2021/2022 off the coast of Crimea (as opposed to the previous two fishing seasons) was characterized by its relatively early start and the shift of the fishing operations eastwards to Cape Chauda.

The resumption of design and survey work for the construction of the Krapivinsky Hydroelectric Power Plant on the Tom River has necessitated the assessment of the current state of its fish resources and called for making the prediction of their transformation in the event of the hydroelectric complex being put into operation. In the early 20th century, the Tom River was classified as a salmonid habitat. At that time, such valuable commercial species as the Siberian taimen Hucho taimen, blunt-snouted lenok Brachymystax tumensis , tugun Coregonus tugun, humpback whitefish Coregonus pidschian, Nickolsky’s grayling Thymallus nikolskyi , nelma Stenodus leucichthys nelma, muksun Coregonus muksun, and peled Coregonus peled were permanent residents. Sturgeons, such as the Siberian sturgeon Acipenser baerii and sterlet Acipenser ruthenus, were also abundant. Currently, out of these species, grayling, occasionally taimen and lenok are caught in the Tom River; the common roach Rutilus rutilus , European perch Perca fluviatilis, Siberian dace Leuciscus baicalensis and Eurasian ruffe Gymnocephalus cernuus comprise 95 % of all fish caught. If construction of the Krapivinsky Reservoir on the Tom River is completed and it is put into operation, a deep-water, slow-flowing “lake-type” water body will be created. The river bed will be blocked, so semi-anadromous fish species, many of which are listed in the Red Data Book-such as Siberian sturgeon, sterlet and nelma,-will disappear. A decrease in the abundance of grayling, taimen and lenok, already low in number, should also be expected. These fish species winter in the pits, some of them migrate to the Ob River, so, after passing the spillway, they will not be able to return upstream to the spawning grounds. The abundance of lake and lake-river species is expected to increase, among them the common roach, dace Leuciscus leuciscus , European perch, Prussian carp Carassius gibelio (introduced locally, subsequently self-dispersed), as well as common bleak Alburnus alburnus and sunbleak Leucaspius delineates (accidental invaders). In the future, it is possible to make an attempt to introduce peled to the upper basin of the Krapivinsky Reservoir. There is a prospective threat of the Chinese sleeper Perccottus glenii spreading in the upcoming reservoir, which can severely undermine its fish stocks.

Considerable inter-annual variations of water temperature and salinity in the Azov Sea necessitate their constant monitoring. Following the numerous studies undertaken in this area, this work presents the specific features of inter-annual changes in temperature and salinity of the sea surface layer, averaged for the summer seasons of 1989-2021 both for the Azov Sea (excluding Taganrog Bay) and for its various areas; two representative time spans, 1989-2004 and 2005-2021, have been identified. The first time span was characterized by a relatively wide variation range of the temperature and by its decreased values, as well as by the decrease in the salinity. During the second time span, an increase in the both temperature and salinity of the sea surface layer occurred in the sea and its regions, which was induced by the increase in the air temperatures in the area and by the reduction of the relatively cold Don River runoff after 2005 in the case of the first parameter, and, for the second parameter, it resulted from the decrease in the runoff of the both Don and Kuban Rivers. Correlation analysis of the series of the summer temperature and salinity values by area and for the sea on the whole as they relate to the annual and maximum runoff of the Don River (Razdorskaya) and to the annual runoff of the Kuban River (Krasnodar and the river mouth) for 1989-2021 has shown the absence of the significant relationship with temperature and its presence with salinity both for the sea and for most of its regions at the confidence level of 99 % for the Don River runoff and 95 % for the Kuban River runoff.

Formation of the European anchovy Engraulis encrasicolus (Linnaeus, 1758) stocks in the Azov Sea depends on the development of zooplankton, which is the main food source for this fish species. Under the conditions of the natural flow regime of the rivers (1937-1951) and the 10.6 ‰ salinity of the sea, native zooplankton species ensured a high food supply for the anchovy, which resulted in relatively large anchovy stocks. During the Azov Sea salinization up to 12.8 ‰ that occurred in the late 60-70s of the last century, the zooplankton species composition changed. Predatory scyphoid jellyfish species - Aurelia aurita and Rhizostoma pulmo - underwent drastic increase in abundance, which led to the reduction in the summer biomass of the zooplankton almost by half. During that period, large stocks of the European anchovy developed less often. In the late 1980s, as a result of the introduction of a predatory ctenophore Mnemiopsis leidyi in the Azov Sea, the summer biomass of the zooplankton decreased further by 2-3 orders of magnitude. During the feeding season of the European anchovy, the areas with high zooplankton productivity disappeared, which resulted in the recurring low stocks of this fish species. At the end of the 1990s, a ctenophore Beroe ovata , feeding on the mnemiopsis, appeared in the Azov Sea. Its invasion led the delayed entry of the mnemiopsis into the sea, which, in turn, ensured the development of a sufficient food supply for the anchovy during its pre-spawning period. However, the main feeding season of the anchovy, just as before the arrival of B. ovata , took place under a shortage of the food supply. In the last few years, another increase in salinity to 15.0 ‰ is observed in the Azov Sea. The Black Sea jellyfishes A. aurita and R. pulmo are actively developing once again and, along with M. leidyi , provide even stronger food competition for the anchovy. During these years, only low-productive generations and low stocks of this fish species have been observed.
Criterios Clave en la Selección de Pacientes Candidatos para el Tratamiento Quirúrgico de la Enfermedad de Parkinson

La selección del paciente candidato para el tratamiento quirúrgico de la enfermedad de Parkinson representa una etapa fundamental para asegurar la máxima eficacia y la menor posibilidad de aparición de efectos indeseables. Los criterios clínicos predictivos de mayor relevancia para la enfermedad de Parkinson (EP) están representados principalmente por: diagnóstico certero, edad menor de 70 años, respuesta a la L-dopa mayor del 30%, ausencia de deterioro cognitivo conductual (de acuerdo con las diferentes escalas de evaluación clínica) o de depresión e ideación suicida.Los denominados síntomas axiales (entre los cuales se incluyen principalmente la acinesia o «congelación» al caminar, y los trastornos del habla y el equilibrio) que no tengan una adecuada respuesta al tratamiento dopaminérgico, probablemente no serán modificados por la cirugía en gran medida.En relación a las fluctuaciones motoras y las discinesias asociadas al tratamiento sustitutivo, tales como las discinesias bifásicas y de pico de dosis y las distonías ON- OFF, independientemente de la magnitud y la duración, todas presentarán una adecuada y sostenida respuesta. Esto, sumado a los efectos beneficiosos sobre los síntomas cardinales, indicaría que la estimulación cerebral profunda (ECP) representa un método seguro y eficaz, aunque no evita de modo alguno la progresión de la enfermedad.

The Effect of Heat Treatment and Build Orientation on the Susceptibility of Laser Powder Bed Fusion Additively Manufactured Alloy 625 to Crevice Corrosion

Published: April 2024

This study aimed to determine the optimal heat treatment and build orientation to minimize the susceptibility of additively manufactured (AM) Alloy 625 to crevice corrosion. To accomplish this, metal-to-metal and acrylic-to-metal remote crevice assembly (RCA) experiments were performed for as-made (NT) AM, stress-relieved (SR) AM, solution-annealed AM, and solution plus stabilization-annealed AM Alloy 625 in two different build orientations. Current vs. time data from metal-to-metal RCA experiments were analyzed using commercially available statistical analysis software used to perform analysis of variance. While there was a lack of statistical evidence that build orientation affects crevice corrosion susceptibility, there was strong evidence heat treatment affects crevice corrosion susceptibility. Specifically, according to Tukey’s Multiple Comparison, alloys that were heat treated had a statistically significant lower charge passed as compared to the NT specimens. This finding was consistent with measured penetration depth where NT AM specimens had the largest maximum penetration depth. In contrast, acrylic-to-metal RCAs were used to calculate crevice corrosion current density (rate) and repassivation potential. While current densities for the AM materials were comparable, the forward motion of the active crevice corrosion front on the NT and SR specimens was found to be slow, resulting in high damage accumulation locally. Both metal-to-metal and acrylic-to-metal RCA results are discussed within the context of nonhomogenized microstructures associated with AM.

The experience a teacher has may influence his or her beliefs about mathematics. This research describes the beliefs of junior high school mathematics teachers from teaching experience. The respondents to this research were six teachers who had different teaching experiences. Interview techniques were used to obtain research data. To ensure the credibility of the research data, source triangulation was carried out. The results show that mathematics teachers with more than 30 years of teaching experience believe that mathematics is an absolute science, there are arguments for solving problems. Mathematics teachers with 11 – 30 years of teaching experience believe that mathematics covers various fields of science and various scientific disciplines require mathematics. This shows that all areas of life use mathematics. Mathematics teachers with less than 10 years of teaching experience believe that mathematics is a comprehensive science that is interconnected and integrated with social, historical, political and cultural practices. This research illustrates that teaching experience has an impact on differences in teachers' beliefs about mathematics.

Published: April 2024

This paper investigates the critical roles of soil surveys and lithologic evaluation in identifying potential mineral resources. Soil surveys involve the systematic mapping, examination, description, and classification of soils within a defined area. Through targeted sampling and laboratory analysis, these surveys can reveal the concentration of metals in the soil. By analyzing these metal signatures, geoscientists can infer the underlying geology and identify areas with a higher likelihood of hosting valuable mineral deposits. Lithologic evaluation complements soil surveys by focusing on the physical characteristics of rock units exposed at outcrops, in hand samples, or cores. Observable with the naked eye or a magnifying lens, these characteristics include color, texture, and structural features. Lithogeochemistry, or rock geochemistry, builds upon this foundation by analyzing the chemical composition of the bedrock. This analysis aims to identify spatial patterns of elements typically associated with specific types of mineral deposits. By integrating the findings from soil surveys and lithologic evaluations, geoscientists gain a comprehensive understanding of the subsurface environment, enabling them to prioritize areas for further mineral exploration activities. This paper delves into the fundamentals of these techniques, highlighting their strengths and limitations in the context of mineral resource exploration.

Published: April 2024

Gender equity in education stands as a cornerstone for fostering social empowerment and advancing towards a more inclusive society. This review delves into the challenges hindering gender equity in education and the pathways to promote opportunities for social empowerment. Despite considerable progress, disparities persist in access to education based on gender. Girls, particularly in marginalized communities, face barriers such as cultural norms, economic constraints, and inadequate infrastructure, limiting their educational opportunities. Furthermore, gender stereotypes perpetuate disparities in subject choices and career aspirations, restricting girls' access to fields such as science, technology, engineering, and mathematics (STEM). Addressing these challenges requires a multi-faceted approach. Firstly, policy interventions must prioritize equitable access to education, ensuring the removal of financial, cultural, and institutional barriers. Investing in infrastructure, scholarships, and targeted initiatives can mitigate disparities and enable girls to pursue education freely. Secondly, addressing socio-cultural norms and stereotypes is crucial. Educational curricula should be designed to challenge gender biases and promote inclusivity. Additionally, engaging communities and stakeholders in dialogue and awareness campaigns can foster a supportive environment for gender equity in education. Promoting opportunities for social empowerment through education necessitates holistic strategies. Beyond access, quality education must equip students with critical thinking skills, confidence, and agency to challenge systemic inequalities. Encouraging girls' participation in STEM fields and non-traditional careers can expand their economic opportunities and challenge gender norms. In conclusion, achieving gender equity in education is indispensable for social empowerment. By addressing challenges and promoting inclusive opportunities, we can foster a society where every individual, regardless of gender, can realize their full potential.

Published: April 2024

Abstract. The urgent need to mitigate climate change has evoked a broad interest in better understanding and estimating nitrous oxide (N2O) emissions from different ecosystems. Part of the uncertainty in N2O emission estimates still comes from an inadequate understanding of the temporal and small-scale spatial variability of N2O fluxes. Using 4.5 years of N2O flux data collected in a drained peatland forest with six automated chambers, we explored temporal and small-scale spatial variability of N2O fluxes. A random forest with conditional inference trees was used to find immediate and delayed relationships between N2O flux and environmental conditions across seasons and years. The spatiotemporal variation of the N2O flux was large, with daily mean N2O flux varying between −10 and +1760 µgN2Om-2h-1 and annual N2O budgets of different chambers between +60 and +2110 mgN2Om-2yr-1. Spatial differences in fluxes persisted through years of different environmental conditions. Soil moisture, water table level, and air temperature were the most important variables explaining the temporal variation of N2O fluxes. N2O fluxes responded to precipitation events with peak fluxes measured on average 4 d after peaks in soil moisture and water table level. The length of the time lags varied in space and between seasons indicating possible interactions with temperature and other soil conditions. The high temporal variation in N2O flux was related to (a) temporal variation in environmental conditions, with the highest N2O fluxes measured after summer precipitation events and winter soil freezing, and (b) to annually varying seasonal weather conditions, with the highest N2O emissions measured during wet summers and winters with discontinuous snow cover. Climate change may thus increase winter N2O emissions, which may be offset by lower summer N2O emissions in dry years. The high sensitivity of N2O fluxes to seasonal weather conditions suggests increasing variability in annual peatland forest N2O budgets as the frequency of extreme weather events, such as droughts, is predicted to increase.

Abstract. Climate change is projected to increase the frequency and intensity of extreme rainfall events in the Mediterranean region, increasing runoffs of terrestrial matter into coastal waters. To evaluate the consequences of terrestrial runoff for plankton key processes, an in situ mesocosm experiment was conducted for 18 d in the spring of 2021 in the coastal Mediterranean Thau Lagoon. Terrestrial runoff was simulated in replicate mesocosms by adding soil from an adjacent oak forest that had matured in water from the main tributary river of the lagoon. Automated high-frequency monitoring of dissolved oxygen, chlorophyll a fluorescence, salinity, light, and temperature was combined with manual sampling of organic and inorganic nutrient pools, pH, carbonate chemistry, and maximum quantum yield (Fv:Fm) of photosystem II (PSII). High-frequency data were used to estimate the gross primary production (GPP) of oxygen, community respiration (CR), and phytoplankton growth (μ) and loss (L) rates. During the first half of the experiment (d2–d11), the simulated runoff reduced light availability (−52 %), chlorophyll a concentrations (−70 %), and phytoplankton growth rates (−53 %). However, phytoplankton maintained a certain level of primary production by increasing its photosynthetic efficiency. Meanwhile, the runoff enhanced CR (+53 %), shifting the metabolic status (GPP : CR) of the system toward heterotrophy and increasing the partial pressure of carbon dioxide (pCO2), potentially switching the direction of the air–sea CO2 exchange. However, during the second part of the experiment (d11–d17), remineralized nutrients boosted phytoplankton growth (+299 %) in the terrestrial runoff treatment but not its loss rates, leading to phytoplankton biomass accumulation and suggesting a mismatch between phytoplankton and its predators. Our study showed that a simulated terrestrial runoff significantly affected key plankton processes, suggesting that climate-change-related increases in runoff frequency and intensity can shift the metabolic balance of Mediterranean coastal lagoons towards heterotrophy.
Substorm Signatures in the Dayside Magnetosphere

Published: April 2024

Abstract. We investigate variations in the position of the magnetopause in response to the interplanetary magnetic field (IMF), and different phases of magnetospheric substorms. The average location of magnetopause is examined using magnetic field observations from multiple satellites (THEMIS, RBSP, and MMS), and the Shue model utilizing OMNI solar wind data for a period of five years from 2016–2020. We estimate average position of the magnetopause using Shue model through superposed epoch analysis of standoff distance and tail flaring angle at different substorm timings (onset, peak and end) and from in-situ measurements through 2D equatorial maps of average Δ BZ under IMF |Bz|> 0 conditions. Our findings reveal the occurrence of substorms during both northward and southward IMF orientations and highlight an earthward movement of the magnetopause during substorm onset and peak, followed by a relaxation during the substorm end time, for both northward and southward IMF orientations. Notably, the magnetopause undergoes significant compression and reaches its closest point to the Earth during instances of strong southward IMF (BZ < -5), particularly during the substorm peak. The empirical model provides accurate estimation of the magnetopause location during periods of both strong northward and southward IMF |Bz|>5, as the model curve traverses a distinct location (Δ BZ = 0) representing the magnetopause shown in the 2D average map of Δ BZ.

Abstract. Global and basin-scale ocean reanalyses are becoming easily accessible and are utilized widely to study the Southern Ocean. Yet, such ocean reanalyses are optimized to achieve the best model-data agreement for their entire model domains and their ability to simulate the Southern Ocean requires investigations. Here, we compare several Massachusetts Institute of Technology general circulation model (MITgcm)-based ocean reanalyses (ECCOv4r5, ECCO LLC270, B-SOSE, and GECCO3) for the Southern Ocean. For the open ocean, the simulated time-mean hydrography and ocean circulation are consistent with observations. The MITgcm-based ocean reanalyses show Antarctic Circumpolar Currents (ACC) measuring approximately 149±11 Sv. The simulated 2 °C isotherms are located in positions similar to the ACC and roughly represent the southern extent of the current. Simulated Weddell and Ross Gyre strengths are 51±11 Sv and 25±8 Sv, respectively, consistent with observation-based estimates. However, our evaluation finds that the time evolution of the Southern Ocean is not well simulated in these ocean reanalyses. While observations showed little change in open-ocean properties in the Weddell and Ross Gyres, all simulations showed larger trends, most of which are excessive warming. For the continental shelf region, all reanalyses are unable to reproduce observed hydrographic features, suggesting that simulated physics determining on-shelf hydrography and circulation is wrong. Nevertheless, ocean reanalyses are valuable resources and can be used for generating ocean lateral boundary conditions for regional high-resolution simulations. We recommend that future users of these ocean reanalyses pay extra attention if their studies target open-ocean Southern Ocean temporal changes or on-shelf processes.
Cultural Seascapes, Regional Connections, and Colonial Powers in the Southwestern Pacific
Authors: Tiapa Francisco
Published: April 2024

Between the second half of the nineteenth and the first half of the twentieth century, Australia and the islands of the southwestern Pacific were the setting of a wide context of encounters between Europeans and Indigenous peoples, in regions that could be perceived as disconnected at a first glance. However, it was part of a wider project of colonization that overlapped on a not less wide set of Indigenous networks of interconnection. Such a colonial project had landscape modification as a main common goal, added to projects of ethnic and cultural separation and segregation. This article suggests an approach to cultural seascapes as an approach to power relations between European colonizers and Indigenous people in this region. I suggest that this level of analysis allows to connect realities that could be perceived as disparate, but which were coherent with global projects of imposition of colonial identities according to a dominant global matrix of power. I aim to highlight the value of local spaces of interconnection as expressions of wider realities, approachable throughout the analysis of cultural seascapes as mobile spaces of power relations.
Anarchy in the World-System
Authors: Demirel Ege
Published: April 2024

The world-system has been in a crisis for a while. The decline of U.S. hegemony, the rise of China, and Russia’s assertive foreign policy are the most important issues regarding the course of the world-system. On the one hand, the United States and its allies (in Samir Amin’s words, “the triad”) have desperately tried to protect the status quo. On the other hand, China and Russia have tried to create an alternative to sustain the capitalist world-system instead of U.S. hegemony. For this reason, to analyze the world-system, I argue that core-periphery relations should be reevaluated regarding China and Russia with the concept of semi-core. This study aims to evaluate the possible outcomes and prospects in the world-system in light of the rivalry between core and semi-core, and asserts that the world-system is in the phase of interregnum that consists of instabilities and disorders. This phase of interregnum has stemmed from the existence of semi-core and the structural crisis of the system.
Tamaño e Intensidad de uso de las Redes Sociales Digitales: ¿Cómo se Relacionan con las Habilidades Personales y Sociales Percibidas por los Universitarios?
Authors: Villalustre-Martínez Lourdes , Cueli Marisol
Published: April 2024

Introducción. Existen una serie de habilidades de carácter personales y sociales que presumiblemente resultan relevantes no sólo en la interacción cara a cara sino también a través de las redes sociales digitales (RSD). El presente trabajo analiza el perfil de interacción en RSD en base al sexo, la edad, el tamaño de las RSD y la intensidad de su uso. Además, se analiza las habilidades personales y sociales en RSD percibidas por un grupo de universitarios y en qué medida variables como el sexo, la edad, el tamaño de las RSD y la intensidad de su uso, predicen las habilidades personales y sociales en RSD.  Método. Participaron en el estudio un total de 257 universitarios que completaron el Cuestionario de Percepción de Habilidades Personales y Sociales en RSD. Resultados. Los resultados reflejaron que los hombres poseían RSD de mayor tamaño, mientras que la intensidad de uso era superior en las mujeres. En lo que se refiere a la edad, aquellos universitarios más jóvenes poseían RSD con mayor tamaño y más intensidad de uso. De igual modo, los universitarios indicaron que ponían en juego en mayor medida habilidades personales con el uso de las RSD en detrimento de las habilidades sociales, y estas habilidades no se relacionaban con el sexo ni con la edad, pero sí con el tamaño e intensidad de uso de las RSD. Discusión. En definitiva, quienes cuenten con redes más amplias y con mayores posibilidades de interacción, alcanzarían un mejor nivel de habilidades personales, mientras que quienes dedican más tiempo, podrían fomentar sus habilidades sociales en el marco de las RSD.
Pegagogías alternativas y bienestar: una revisión sistemática
Authors: Marticorena Miguel , Pasmanik Diana
Published: April 2024

Este estudio es una revisión sistemática de la literatura publicada desde el año 2018 a junio 2022 acerca del bienestar y el bienestar subjetivo y las pedagogías alternativas, respecto de los estudiantes preescolares y escolares. Cumple con el propósito de caracterizar la investigación sobre bienestar y bienestar subjetivo y educación alternativa en cuanto a la definición de bienestar y bienestar subjetivo a las que adscriben los artículos sobre la materia en las bases de datos Web of Science y Scopus. La muestra final la componen 22 artículos distribuidos en dos tipos de pedagogías alternativas: Montessori y Escuela Bosque. El concepto de bienestar mostró una variedad de connotaciones. Incluyen desde su presentación a partir de definiciones preexistentes en la literatura especializada, hasta simplemente su mención sin mayor explicación. En general, se le entiende como bienestar socioemocional, en ambas pedagogías, coincidiendo con uno de los sellos distintivos de la Educación Alternativa. El bienestar subjetivo muestra una presencia muy reducida, asociada a definiciones preexistentes. Se detectó un número creciente de publicaciones teóricas y empíricas sobre educación alternativa durante los últimos cinco años, denotando un mayor interés por este tipo de educación y sus posibilidades. Los resultados sugieren la conveniencia de seguir desarrollando investigación en esta temática.
Percepción del alumnado universitario español de los Grados de Maestro/a sobre la mención en Educación Musical: estudio de caso
Authors: Pérez-Eizaguirre Miren , Morales Ángela , Cuenca-Rodríguez Mª Elena , Privado Jesús
Published: April 2024

El conocimiento que el alumnado actual posee sobre las menciones de los grados de Maestro/a es un campo de interés para saber en qué punto se encuentran con respecto a sus elecciones en relación con sus salidas profesionales. Esta investigación pretende explorar las diferencias de la percepción sobre las menciones en función del sexo, el grado estudiado (Doble grado o Infantil/Primaria) y el curso (2º, 3º, 4º o 5º) y si el hecho de poseer estudios previos musicales influye en la percepción de las menciones. También analizar el papel que tiene en esta percepción el hecho de haber trabajado aspectos musicales en el instituto. Se aplicó un cuestionario a 337 alumnos de los cursos 2º, 3º, 4º y 5º del Grado de Maestro en Educación Infantil, Maestro en Educación Primaria y Doble grado en Maestro en Educación Infantil y Maestro en Educación Primaria de la Universidad Autónoma de Madrid, Universidad de Castilla-La Mancha, Universidad de Salamanca y Universidad de Murcia. Se analizaron los datos en primer lugar realizando los estadísticos previos de las principales medidas del cuestionario. En segundo lugar, se llevó a cabo un Análisis Factorial Exploratorio y por último se estudiaron las diferencias mediante pruebas t de Student. Finalmente, se estudiaron asociaciones entre las medidas de percepción de las menciones y el resto de las medidas categóricas usando pruebas χ2 de Pearson, además, del cálculo de la V de Kramer como índice de asociación. Se concluye insistiendo en la necesidad de más información con respecto a la definición de las menciones y a sus salidas profesionalizantes en el alumnado actual.
¿Cómo motivan los profesionales del ámbito educativo a su alumnado con necesidades específicas de apoyo educativo?
Authors: Fernández Suárez Ana Patricia , Suárez Riveiro José Manuel
Published: April 2024

La motivación académica del alumnado está considerada como uno de los elementos más relevantes para su éxito y el rendimiento académico. Su estudio ha sido desarrollado fundamentalmente desde una perspectiva interna del propio alumnado. Sin embargo, dicha motivación académica está influida también por los elementos del entorno, entre los que destaca el papel del profesorado. Esta función motivadora será especialmente relevante en el caso del alumnado con necesidades específicas de apoyo educativo. Pese a ello, esta línea de investigación ha sido prácticamente inexistente.
Se ha utilizado una muestra de 796 profesionales del ámbito educativo, mayoritariamente maestros y profesores, que desarrollan su actividad educativa con alumnado con Necesidades Específicas de Apoyo Educativa (NEAE) de 3 a 16 años. Se han realizado análisis descriptivos, correlacionales e inferenciales.
Los resultados obtenidos nos informan sobre cómo los profesionales del ámbito educativo utilizan los distintos tipos de conductas motivadoras con su alumnado. Así, hemos obtenido una mayor utilización de la generación de expectativas y refuerzos positivos, mientras que la menor utilización se produce en la generación de meta de autofrustración del ego. Además, se han obtenido diferencias significativas con respecto al sexo, a la profesión, a la ubicación, a la edad y a la experiencia.
Este estudio nos ha servido para arrojar algo de luz sobre cómo los distintos profesionales del ámbito educativo motivan a su alumnado, lo cual tiene importantes implicaciones para la práctica educativa y más directamente para el papel que debe desempeñar el profesorado en relación con su alumnado.
Confluencias entre pensamiento crítico y redes sociales en el ámbito educativo. Mapeo de experiencias y detección de desafíos a través de una revisión sistemática
Authors: Escribano-Muñoz Carmen , Gil-Fernández Raquel , Calderón-Garrido Diego
Published: April 2024

Las redes sociales se han convertido en el canal de comunicación y en el medio habitual de información por excelencia. Con ello, se ha incrementado la preocupación sobre las consecuencias de su uso, y de qué manera pueden influir en a la hora de enfrentar problemas sociales y construir identidades. Por tanto, se plantean nuevos desafíos en el mundo educativo en los que el pensamiento crítico constituye una competencia transversal cada vez más necesaria. Partiendo de este contexto, el presente trabajo tiene como objetivo analizar cómo la literatura científica ha tratado el desarrollo del pensamiento crítico en el ámbito educativo en las redes sociales durante el período 2012-2021 mediante una revisión sistemática de la misma. La búsqueda se ha centrado en la Core Collection de la Web of Science (WoS) y se ha acometido la revisión mediante un método mixto. Los principales resultados muestran que el desarrollo del pensamiento crítico debe estar vinculado al uso de las redes sociales, y se remarca la necesidad de educar el pensamiento crítico desde la perspectiva de la alfabetización crítica digital. Sin embargo, se detecta escasez de producción científica que orienten unas políticas educativas para abordarlas en las aulas, lo que implica el desafío de abrir nuevas vías de investigación en esta línea.
Wine tokenisation: the opportunity of DLT technology for the economic and social challenges of the wine sector
Authors: Ibáñez-Jiménez Javier W. , Palomo-Zurdo Ricardo
Published: April 2024

La tokenización del vino es uno de los retos más formidables a los que se enfrenta la industria vitivinícola en el proceso de digitalización de los próximos años. La viticultura y el sector vitivinícola en toda su cadena de valor están experimentando una transformación radical. Actores relevantes en IA, DLT e IoT y líderes de la comunidad científica en química, ingeniería, economía y derecho compartían la idea de dar un giro a la cooperación interprofesional de la vid y el vino en materia de identidad digital e intercambio de datos en los procesos de autenticación digital y trazabilidad comercial de la vid y el vino. Esta contribución plantea cuestiones clave al respecto, en el contexto del desarrollo de nuevos mercados del vino tokenizados por DLT y centros sociales, previendo formas transdisciplinares de superar las principales amenazas económicas y barreras legales.
