Az öregedés természetes velejárója az agyi működések változása, így nehezebb neveket felidézni, számokat megjegyezni, új dolgokat megtanulni. A szellemi hanyatlás, a demencia azonban nem része a természetes öregedésnek. A demencia elsősorban az idősek betegsége. Az Alzheimer demencia agyi kórfolyamatai jóval a klinikai kép megjelenése előtt már elkezdődnek, enyhe kognitív zavar (EKZ) egy része ennek következménye lehet. Ebben a stádiumban felismerni a kognitív funkciók zavarát adhat arra lehetőséget, hogy lassítható legyen a folyamat, ill. amint oki kezelés elérhetővé válik, be lehessen avatkozni. A „Teszteld a memóriád” (TYM-HUN) rövid önkitöltős teszt alkalmas a demencia szűrésére és várhatóan alkalmas az EKZ felismerésére is.

Published: October 2020

Tanulmányunk célja az időskori szerencsejátékkal kapcsolatos vizsgálatok és tanulmányok rövid összefoglalása és elemzése. A fiatal és felnőttkori szerencsejátékkal kapcsolatosan kiterjedt kutatások állnak rendelkezésre, ismerjük a kórkép kialakulásában és fennmaradásában szerepet játszó fontosabb demográfiai jellemzőket, személyiségfaktorokat és terápiás lehetőségeket. Az időskori szerencsejátékkal kapcsolatosan kevés a vizsgálati eredmény külföldön és Magyarországon még nincs kifejezetten 65 év feletti szerencsejátékosokra fókuszáló tanulmány. Ezért ebben az összefoglalóban kizárólag külföldi vizsgálatokra támaszkodhatunk, a speciális minta következtében azonban a tanulmányok és következtetések száma korlátozott. Az eredmények alapján az időskori szerencsejáték különbözik a fiatal és serdülőkori szerencsejátéktól.

Giant pedunculated hepatic hemangioma necessitating surgical excision in a neonate: A case report
Authors: Almuawi Abdulrahman , Daboos Mohammed , Prasad Ramakrishna
Published: October 2020

Background: Hepatic hemangioma (HH) is the most common hepatic tumor in small infants. It rarely presents during the neonatal period. Fetal giant hepatic hemangiomas tend to result in hydrops fetalis and cardiac failure due to cardiovascular overload. The purpose of this case report is to demonstrate the importance of pre and postnatal diagnosis of liver hemangioma with unusual presentation in neonatal life with huge mass causing respiratory compromise, and bowel compression.
Case Presentation: We present a rare case of giant pedunculated hepatic hemangioma, diagnosed prenatally as a huge intra-abdominal mass. Patient developed respiratory distress due to large abdominal mass, thrombocytopenia, anemia and bowel compression thus necessitated surgical excision. Postoperative recovery was uneventful.
Conclusion: Giant hepatic hemangioma may become fatal due to a huge mass effect on respiration and bowel function, along with associated thrombocytopenia and anemia. Adequate monitoring and support are mandatory in such cases and surgical excision at times becomes lifesaving.

АЛЬ-ФАРАБИ И МУЗЫКА (AL-FARABI AND MUSIC)
Authors: Kosanova Aigul
Published: October 2020

Іn this article, the author examines the scientific heritage of the great thinker and philosopher of the East, Abu Nasir al Farabi. The contribution of the word is analysed.
Abu Nasr Muhammad Ibn Tarkhan Ibn Uzlag al-Farabi (870-950) was born in the city of Farab (Otrar) on the territory of the modern South Kazakhstan region. In the early middle ages, Otrar was called Farab. The city of Otrar was the second major cultural, commercial, political and scientific center, the center of the ancient culture of Kazakhstan and Central Asia.
The most famous of his scientific works is" treatise on the views of good citizens "("views of good citizens"). "The scientist divides the city leaders into "benevolent and ignorant". At that time, there was a city-state. When will its inhabitants be happy? According to the scientist, this depends on the mayors of the cities. If the mayor is educated, fair, and clean-minded, all citizens will be happy. And if the mayor of the city is ignorant and lies, then the people of the city will be unhappy. Al-Farabi says that in order to achieve true happiness, a person must constantly seek. Human behavior should also be good," Zhakypbek Altayevich says in the documentary "Al - Farabi-philosopher of civilization". In addition, Al-Farabi's work "the great treatise on music" has been translated into many languages of the world.
ЭФФЕКТИВНОСТЬ ПРОГРАММ ISPRING ПРИ ДИСТАНЦИОННОМ ОБУЧЕНИИ(EFFICIENCY OF ISPRING PROGRAMS IN DISTANCE LEARNING)
Authors: Otarbekova Zhamilya , Dautkulova Akmaral
Published: October 2020

The need to improve distance learning technologies in the modern education system is urgent. Although e-textbooks and various educational resources have been developed for many secondary schools, such resources in higher education institutions are insufficient. For active communication and effective feedback between students and teachers, it is necessary to develop electronic textbooks. Creation of a high-quality electronic textbook is a complex, laborious process that requires the participation of a number of specialists: editors, designers, programmers. And today, with the transition to mass distance learning, it has become possible to satisfy the need for the rapid development and use of electronic textbooks using iSpring products. With iSpring, a teacher independently can not only record a video for each lecture, but also prepare various interactive tasks and tests, and receive ready-made results of completed tests and assignments. ISpring Learn for Distance Learning allows you to actively lead the learning process and track learning outcomes. As part of the article, we aim to show how to prepare electronic assignments in the modern Kazakh language using iSpring Suite - 9.

Authors: Koltsov Petr , Umgaev Semyon
Published: October 2020

This article examines the prospects of the Russian Federation and the Republic of Kazakhstan in the field of cross-border, interregional, trade, economic and integration cooperation. Including participation in integration processes within the framework of the EAEU and the CSTO, the areas of cross-border and interregional cooperation, are examples of a successful model of interregional cooperation. Integration potentials of the post-Soviet space are analyzed.
The principles of economic bases of interaction, adopted during the national economic period of the USSR, determined the established process of Kazakh-Russian relations after the collapse of the Soviet Union.
Kazakhstan inherited from the common economic system of the USSR a part of the unified production infrastructure, which in the 90s became even more relevant for economic cooperation between the Russian Federation and the Republic of Kazakhstan.
In the field of integration processes in the post-Soviet and Eurasian space, Russia and Kazakhstan are also leaders, which in many ways shape and set the pace of integration processes.
According to the authors, important factors for integration processes are: geographical factor, demographic factor, economic resources, military-political factor, political factor, cultural factor, social factor, as well as reputation, information and educational resources.
Making the most of introverted leadership in a world of extroverts
Authors: Agarwal Ekta
Published: October 2020

In this competitive world everyone strives to become a good leader. Generally, people have a notion that extroverts are better leaders than introverts (Cain, 2013). But recent results (Cain, 2013), are in contradiction with these peoples’ beliefs. As we advance in our careers, individual expectations increase as we need to collaborate with others for the growth of the organization (Helgoe, 2013). Due to these expectations, extroverts have the edge when compared to introverts, and hence, this leads to the capabilities of introverts being overlooked (Eve-Cahoon, 2003). It is a general human tendency to define confidence with a person’s level of loudness. As per the research by Laney (2002), loudness should not be a criterion to measure confidence. Being perplexed about our own behavior is the biggest mistake people make. Firstly, people need to understand which scale they pertain to. The research says the best way to understand this scale is by paying attention to what we do, not what we think or say (Cain, 2013). This article gives knowledge about how an introvert holds the capabilities to lead groups and inspire others. Various characteristics of introverted leadership are described with real-time examples and statistics to articulate the difference between extrovert and introvert leadership styles. The goal is not to change introverted leaders, instead it is to understand their preferences and use it as a strength (Kahnweiler, 2009).
Direct assessment of second language writing: Holistic and analytic scoring
Authors: He Ling
Published: October 2020

Direct assessment of second language (L2) writing skill, in which a student is usually assessed by means of an essay on a topic during a limited time period, has been used as a valid measurement of ability to write in comparison to indirect assessment of writing through multiple-choices. Although both direct and indirect assessments have a risk of reliability, it is effectively argued that direct assessment is more representative of the integrative aspects of writing (Coffman,1966; Morris-Friehe & Leuenberger, 1992). In this era of globalization, a large number of culturally and linguistically diverse students seek higher education in North America. Direct assessment of L2 writing skill is widely used to assess these newly-arrived students’ English proficiency for placement decisions at the beginning of their university programs in the target language. As such, understanding direct assessment of L2 writing is paramount to improve assessment procedures for test validity and fairness. This article reviews direct assessment of L2 writing in the existent research literature with an attention to its two major scoring rubrics: holistic and analytic. The literature review concludes that the purpose of the writing task is significant in deciding which scoring method to use in specific contexts.
Debtor’s and creditor’s stronghold: Bankruptcy chapter 7, 11 & 13
Authors: Cajudo Orillaza Faith
Published: October 2020

Bankruptcy law is created to protect debtors from the hands of creditors. This law ensures creditors repay loans by engaging in a particular process. The United States Congress has enacted a decree governing bankruptcy in the form of the Bankruptcy Code. The different types of bankruptcy will be referred to in this article by their chapters: Chapter 7, 11 and 13 (Justia, 2019). This article will identify the differences between these three chapters, their objectives, as well as the advantages and repercussions of each. Further, the non-dischargeable debts, recommendable actions for the filers, numbers of petitioners who have undergone bankruptcy cases, the financial ratio of the petitioners, the common denominator on the filers, and the methodology performed by the chief executive officer (CEO) of the four companies, Coldwater Creek, Kmart, SEARS and Toys “R” Us, will be analyzed. Additionally, the design and methodology for reviving each company that were implemented and applied by each CEO will be examined, and the reasons they were proven ineffective will be offered. By investing more, borrowing can become essential and, liabilities can grow beyond what could be repaid. This results in the filing of bankruptcy for protection from creditors.

Le Corbusier y la fotografía. De la re-producción a la escritura de la villa Church, Ville-d'Avray
Authors: Rojo de Castro Luis
Published: October 2020

El artículo analiza el uso que Le Corbusier hace de la fotografía para la publicación y difusión de su obra en las décadas de 1920 y 1930, proponiendo la Ville D’Avray como ejemplo paradigmático. Apoyándonos en la interpretación de la fotografía surrealista como signo y escritura realizada por  Rosalind Krauss (1981), proponemos una lectura alternativa a la realizada por Colomina (1988) del uso de la fotografía en la edición y publicación. Entendiendo la fotografía como soporte material y repositorio de información –una suerte de archivo visual preparado para ser manejado como evidencia documental pero también como instrumento autónomo en la construcción de nuevos significados, se describe una estrategia de edición de las fotografías caracterizada por la autonomía con respecto a la realidad material y su manipulación con procedimientos próximos al Surrealismo. Desde este punto de vista crítico, la fotografía sería una técnica para producir no ya imágenes sino ‘signos’ cuya función es ensanchar y ampliar nuestro entendimiento de la realidad y de sus potencialidades.
Hospital de Venecia - Feria de Valencia: pas de deux (1965-2002)
Authors: Navarro Pérez M. , Carro Gil F. , Mompó García M.
Published: October 2020

La Feria de Valencia de Guillermo Jullian de la Fuente, sigue a partir de 1967 un camino paralelo al desarrollo del proyecto para el Hospital de Venecia de Le Corbusier. Su construcción materializó, a gran escala, inquietudes arquitectónicas ensayadas por el Maestro en el proyecto para Venecia, que sus últimos colaboradores  llevaron a cabo tras su muerte. Ambas obras podemos entenderlas como el trabajo de un taller de arquitectura, en el que bajo la inspiración de Le Corbusier, se cuenta con la aportación creativa de sus colaboradores: el propio Jullian como “jefe de taller” pero también José Oubrerie, Roggio Andréini  y otro grupo de arquitectos, quienes deciden continuar los trabajos pendientes del atelier de la rue de Sèvres en el pequeño local de la rue Daguerre, el “Atelier Jullian”. Todos ellos son bastante desconocidos en España, y esto contribuyó, a que la única obra realizada en nuestro país por parte de los herederos del taller de Le Corbusier: la Feria de Valencia de 1967, haya prácticamente desaparecido. Este artículo pretende poner en valor aquella arquitectura y reivindicar su importancia.
Superposition of gravity waves with different propagation characteristics observed by airborne and space-borne infrared sounders

Published: October 2020

Abstract. Many gravity wave analyses, based on either observations or model simulations, assume the presence of only a single dominant wave. This paper shows that there are much more complex cases with gravity waves from multiple sources crossing each others' paths.
A complex gravity wave structure consisting of a superposition of multiple wave packets was observed above southern Scandinavia on 28 January 2016 with the Gimballed Limb Observer for Radiance Imaging of the Atmosphere (GLORIA). The tomographic measurement capability of GLORIA enabled a detailed 3-D reconstruction of the gravity wave field and the identification of multiple wave packets with different horizontal and vertical scales. The larger-scale gravity waves with horizontal wavelengths of around 400 km could be characterised using a 3-D wave-decomposition method. The smaller-scale wave components with horizontal wavelengths below 200 km were discussed by visual inspection.
For the larger-scale gravity wave components, a combination of gravity-wave ray-tracing calculations and ERA5 reanalysis fields identified orography as well as a jet-exit region and a low-pressure system as possible sources. All gravity waves are found to propagate upward into the middle stratosphere, but only the orographic waves stay directly above their source. The comparison with ERA5 also shows that ray tracing provides reasonable results even for such complex cases with multiple overlapping wave packets. Despite their coarser vertical resolution compared to GLORIA measurements, co-located AIRS measurements in the middle stratosphere are in good agreement with the ray tracing and ERA5 results, proving once more the validity of simple ray-tracing models. Thus, this paper demonstrates that the high-resolution GLORIA observations in combination with simple ray-tracing calculations can provide an important source of information for enhancing our understanding of gravity wave propagation.
Using a global network of temperature lidars to identify temperature biases in the upper stratosphere in ECMWF reanalyses

Published: October 2020

Abstract. To advance our understanding of the stratosphere, high quality observational datasets of the upper atmosphere are needed. It is commonplace that reanalysis is used to conduct stratospheric studies. However the accuracy of the standard reanalysis at these heights is hard to infer due to a lack of in-situ measurements. Satellite measurements provide one source of temperature information. As some satellite information is already assimilated into reanalyses, the direct comparison of satellite temperatures to the reanalysis is not truly independent. Stratospheric lidars use Rayleigh scattering to measure density in the upper atmosphere, allowing temperature profiles to be derived for altitudes from 30 km (where Mie scattering due to stratospheric aerosols becomes negligible) to 80–90 km (where the signal-to-noise begins to drop rapidly). The Network for the Detection of Atmospheric Composition Change (NDACC) contains several lidars at different latitudes that have measured atmospheric temperatures since the 1970s, resulting in a long running upper-stratospheric temperature dataset. These temper1ature datasets are useful for validating reanalysis datasets in the stratosphere, as they are not assimilated into reanalyses. Here we take stratospheric temperature data from lidars in the northern hemisphere for winter months between 1990–2017 and compare them with the European Centre for ECMWF's ERA-interim and ERA-5 reanalyses. To give confidence in any bias found, temperature data from NASA's EOS Microwave Limb Sounder is also compared to ERA-interim and ERA-5 at points over the lidar sites. In ERA-interim a cold bias of −3 to −4 K between 10 hPa and 1 hPa is found when compared to both measurement 15 systems. Comparisons with ERA-5 found a small bias of magnitude 1 K which varies between cold and warm bias with height between 10 hPa and 3 hPa, indicating a good thermal representation of the upper atmosphere to 3 hPa. At heights above this, comparisons with EOS MLS yield a slight warm bias and the temperature lidar yield a cold bias. A further comparison is undertaken to see the effects of the assimilation of the Advanced Microwave Sounding Unit-A satellite data and the Constellation Observing System for Meteorology, Ionosphere, and Climate GPS Radio Occulation (COSMIC GPSRO) data on stratospheric temperatures. By comparing periods before and after the introduction of each data source it is clear that COSMIC GPSRO improves the cold bias in the 3 hPa to 0.5 hPa altitude range.
Assessing the vertical structure of Arctic aerosols using tethered-balloon-borne measurements

Published: October 2020

Abstract. The rapidly-warming Arctic is sensitive to perturbations in the surface energy budget, which can be caused by clouds and aerosols. However, the interactions between clouds and aerosols are poorly quantified in the Arctic, in part due to: (1) limited observations of vertical structure of aerosols relative to clouds and (2) ground-based observations often being inadequate for assessing aerosol impacts on cloud formation in the characteristically stratified Arctic atmosphere. Here, we present a novel evaluation of Arctic aerosol vertical distributions using almost 3 years' worth of tethered balloon system (TBS) measurements spanning multiple seasons. The TBS was deployed at the U.S. Department of Energy Atmospheric Radiation Measurement Program's facility at Oliktok Point, Alaska. Aerosols were examined in tandem with atmospheric stability and ground-based remote sensing of cloud macrophysical properties to specifically address the representativeness of near-surface aerosols to those at cloud base. Based on a statistical analysis of the TBS profiles, ground-based aerosol number concentrations were unequal to those at cloud base 86 % of the time. Intermittent aerosol layers were observed 63 % of the time due to poorly mixed below-cloud environments, mostly in the spring, causing a decoupling of the surface from the cloud layer. A uniform distribution of aerosol below cloud was observed only 14 % of the time due to a well-mixed below-cloud environment, mostly during the fall. The equivalent potential temperature profiles of the below-cloud environment reflected the aerosol profile 89 % of the time whereby a mixed or stratified below-cloud environment was observed during a uniform or layered aerosol profile, respectively. In general, a combination of aerosol sources, thermodynamic structure, and wet removal processes from clouds and precipitation likely played a key role in establishing observed aerosol vertical structure. Results such as these could be used to improve future parameterizations of aerosols and their impacts on Arctic cloud formation and radiative properties.
Improved chloride quantification in quadrupole aerosol chemical speciation monitors (Q-ACSMs)

Abstract. Particulate chloride is an important component of fine
particulate matter in marine air masses. Recent field studies also report
elevated concentrations of gas-phase reactive chlorine species and
particulate chloride related to anthropogenic activities. This work focuses
on particulate chloride detection and quantification issues observed for
some quadrupole aerosol chemical speciation monitors (Q-ACSMs) which are
designed for the long-term measurement of ambient aerosol composition. The ACSM
reports particle concentrations based on the difference between measurements
of ambient air (sample mode) and particle-free ambient air (filter mode).
For our long-term campaign in Krakow, Poland, the Q-ACSM reports apparent
negative total chloride concentration for most of the campaign when analyzed
with the default fragmentation table. This is the result of the difference
signal from m∕z 35 (35Cl+) being negative, which dominates over the
positive difference signal from m∕z 36 (H35Cl+). Highly time-resolved
experiments with NH4Cl, NaCl and KCl particles show that the signal
response of m∕z 35 is non-ideal when the signal builds up and decreases
slowly for all three salts, leading to a negative difference measurement. In
contrast, the m∕z 36 signal exhibits a near step-change response for NH4Cl
during the sampling and filter period, resulting in a positive difference
signal. The response of m∕z 36 for NaCl and KCl is not as prompt as for
NH4Cl but still fast enough to have a positive difference signal.
Furthermore, it is shown that this behavior is mostly
independent of vaporizer temperature. Based on these observations, this work presents an
approach to correct the chloride concentration time series by adapting the
standard fragmentation table coupled with a calibration of NH4Cl to
obtain a relative ionization efficiency (RIE) based on the signal at
m∕z 36 (H35Cl+). This correction can be applied to measurements in
environments where chloride is dominated by NH4Cl. Caution should be
exercised when other chloride salts dominate the ambient particulate chloride.
Upwelling-induced trace gas dynamics in the Baltic Sea inferred from 8 years of autonomous measurements on a ship of opportunity

Published: October 2020

Abstract. Autonomous measurements aboard ships of opportunity (SOOP) provide in situ data sets with high spatial and temporal coverage. In this study, we use 8 years of carbon dioxide (CO2) and methane (CH4) observations from SOOP Finnmaid to study the influence of upwelling on trace gas dynamics in the Baltic Sea. Between spring and autumn, coastal upwelling transports water masses enriched with CO2 and CH4 to the surface of the Baltic Sea. We study the seasonality, regional distribution, relaxation, and interannual variability of this process. We use reanalysed wind and modelled sea surface temperature (SST) data in a newly established statistical upwelling detection method to identify major upwelling areas and time periods. Strong upwelling events are most frequently detected around August after a long period of thermal stratification, i.e. limited exchange between surface and underlying waters. We found that these strong upwelling events with large SST excursions shape local trace gas dynamics and often lead to near-linear relationships between increasing trace gas levels and decreasing temperature. Upwelling relaxation is mainly driven by mixing and modulated by air–sea gas exchange and possibly primary production. Subsequent warming through air–sea heat exchange has the potential to enhance trace gas saturation. In 2015, quasi-continuous upwelling over several months led to weak summer stratification, which directly impacted the observed trace gas and SST dynamics in several upwelling-prone areas. We introduce an extrapolation method based on trace gas – SST relationships that allows us to estimate upwelling-induced trace gas fluxes in upwelling-affected regions. In general, the surface water reverses from CO2 sink to source and CH4 outgassing is intensified as a consequence of upwelling. We conclude that upwelling is an important and relevant process controlling trace gas dynamics in near-coastal environments in the Baltic Sea, and that SOOP data, especially when combined with other data sets, enable flux quantification and process studies on larger spatial and temporal scales.
Relevance of acoustic methods to quantify bedload transport and bedform dynamics in large sandy-gravel bed river

Published: October 2020

Abstract. Despite the inherent difficulties to quantify its value, bedload transport is essential to understand fluvial systems. In this study, we assessed different indirect bedload measurement techniques with a reference direct bedload measurement in a section of a large sandy-gravel bed river. Acoustic Doppler Current Profiler (aDcp), Dune Tracking Method (DTM) and hydrophone measurement techniques were used to determine bedload transport rates using calibration with the reference method or using empirical formula. Results show that the hydrophone is the most efficient and accurate method to determine bedload flux in the Loire River. Even though parameters controlling self-generated noise of sediments still need to better understood, the calibration determined in this study allows a good approximation of bedload transport rates. Moreover, aDcp and hydrophone measurement techniques are both able to continuously measure bedload transport associated to bedform migration.
Anatomy of unfolding: The site-specific fold stability of Yfh1 measured by 2D NMR
Authors: Puglisi Rita , Pastore Annalisa , Temussi Piero Andrea
Published: October 2020

Abstract. Most techniques allow detection of protein unfolding either by following the behaviour of single reporters or as an averaged all-or-none process. We recently added 2D NMR spectroscopy to the well-established techniques able to obtain information on the process of unfolding using resonances of residues in the hydrophobic core of a protein. Here, we questioned whether a detailed analysis of the individual stability curves from each resonance could provide additional site-specific information. We used the Yfh1 protein that has the unique feature to undergo both cold and heat denaturation at temperatures above water freezing at low ionic strength. We show that stability curves inconsistent with the average NMR curve from hydrophobic core residues mainly comprise exposed outliers that do nevertheless provide precious information. By monitoring both cold and heat denaturation of individual residues we gain knowledge on the process of cold denaturation and convincingly demonstrate that the two unfolding processes are intrinsically different.
Rapid landslide identification using synthetic aperture radar amplitude change detection on the Google Earth Engine

Published: October 2020

Abstract. The rapid and accurate mapping of landslides is critical for emergency response, disaster mitigation, and improving our understanding of where landslides occur. Satellite-based synthetic aperture radar (SAR) can be used to identify landslides, often within days after triggering events, because it penetrates clouds, operates day and night, and is regularly acquired worldwide. Although there are many landslide detection methods using SAR, most require downloading a large volume of data to a local system and specialized processing software and training. Here we present a SAR-based amplitude change detection approach designed for those without SAR expertise that uses multi-temporal stacks of freely available data from the Copernicus Sentinel-1 satellites to identify landslides on Google Earth Engine (GEE). We provide strategies that can aid in rapid response and event inventory mapping. We test our GEE-based approach in a ~ 277 km2 area in Hiroshima Prefecture, Japan where ~ 3,800 landslides were triggered by rainfall in July 2018. Our ability to detect landslides improves with the total number of SAR images acquired before and after the landslide event, by combining both ascending and descending acquisition geometry data, and by using topographic data to mask out flat areas unlikely to experience landslides. Importantly, our GEE approach allows the broader hazards and landslide community to utilize these state-of-the-art remote sensing data.

La educación está asumiendo un periodo de cambio, propiciado por la inclusión de la tecnología en los distintos espacios de aprendizaje. Una de las tecnologías que está adquiriendo una gran proyección es la realidad aumentada (RA), la cual, para ser aprovechada en su totalidad y obtener los beneficios que reporta en su aplicación, requiere que el profesorado disponga de un pertinente nivel de destrezas tecnopedagógicas. El presente estudio se centra en la Formación Profesional, considerada como una etapa educativa que está emergiendo tanto en el plano académico como en el investigador. Los objetivos formulados se focalizan en conocer la cualificación docente para llevar a cabo propuestas innovadoras con RA y averiguar la influencia de las áreas de la competencia digital del profesorado como predictores de su utilización. Se ha establecido un diseño de corte descriptivo, correlacional y predictivo, basado en un método cuantitativo. Los participantes escogidos configuran una muestra de 627 docentes, a los que se le aplicó un cuestionario para la recogida de datos. Los resultados revelan el uso –aunque no destacado– de la RA y las principales razones por las que no la emplean. Asimismo, se ha hallado un perfil docente que emplea la RA, el cual dispone de un nivel de competencia digital medio y una escasa formación. Las correlaciones establecidas han hallado significancia estadística, mostrando cómo influyen determinadas áreas  y el tipo de formación desplegada en el uso de la RA. Así pues, se han definido las áreas de la competencia digital más determinantes que predicen su empleo por parte de los docentes. Se concluye que el profesorado de Formación Profesional no dispone de una capacitación plena para llevar a cabo una acción pedagógica mediante RA, debido a su nivel medio de competencia digital y a su limitado ejercicio de formación complementaria de tipo tecnopedagógica desplegado.
Las clases basadas en actividad física: una revisión sistemática de las creencias del profesorado y el alumnado
Authors: Zapatero Ayuso Jorge Agustín
Published: October 2020

INTRODUCCIÓN: las clases basadas en actividad física (AF) surgieron como una estrategia para incrementar los niveles de AF, el aprendizaje y el desarrollo del alumnado en la escuela. La investigación sobre la efectividad de estos programas mantiene ciertas incógnitas, por lo que este trabajo busca conocer en profundidad las creencias de los implicados como factor que puede influir en los resultados de estas intervenciones. MÉTODO: se desarrolló una revisión sistemática sobre doce estudios con una metodología cualitativa. Estos fueron seleccionados tras una búsqueda en Web of Science y PubMed usando criterios de elegibilidad. Se aplicó un análisis de contenido con procedimientos inductivos, apoyado en el modelo “Grounded Theory” usando Atlas.ti. Este se complementó con un análisis de las características principales de los estudios en Excel. RESULTADOS: las creencias mayoritariamente manifestadas en las investigaciones fueron relativas a la aceptación y rechazo de las clases basadas en AF y a los beneficios y perjuicios percibidos por profesorado y alumnado. Los resultados informaron de una visión positiva del profesorado y alumnado, que expresaron satisfacción e interés en las clases basadas en AF, así como percibieron diversos beneficios derivados de la implementación de estas clases. No obstante, se recogió cierta controversia y se enumeraron algunas dificultades, como la formación y organización de recursos, para la inclusión de estas clases. DISCUSIÓN: se discuten las diferencias encontradas con las creencias, mayoritariamente negativas, manifestadas en otros estudios sobre promoción de AF en la escuela, así como la efectividad de las intervenciones de los estudios seleccionados. Estas diferencias pueden deberse a que en los estudios de esta revisión se formó previamente al profesorado participante o las clases fueron responsabilidad del equipo investigador. Futuros estudios deben profundizar sobre las creencias del profesorado y el alumnado y cómo estas se relacionan con la efectividad de las clases basadas en AF.
Adecuación de recursos instruccionales en ciencias a las preferencias sensoriales del alumnado: un estudio exploratorio en enseñanza secundaria
Authors: Ortega Torres Enric , Solaz-Portolés Joan Josep , Sanjosé López Vicente
Published: October 2020

Introducción: Se ha probado que el aprendizaje mejora cuando los materiales y métodos de enseñanza toman en consideración rasgos individuales diferenciales de cada estudiante. El modelo VARK se ha propuesto para dar cuenta de esas diferencias en lo que respecta a las preferencias o facilidades que cada alumno tiene para aprender a través de un canal sensorial u otro. El objetivo principal del presente trabajo fue determinar el grado de adecuación de los recursos instruccionales que se utilizan en ciencias a las preferencias sensoriales del alumnado de enseñanza secundaria. Método: Se administró el cuestionario VARK, que permite identificar las preferencias sensoriales, a una muestra de 561 estudiantes de diferentes cursos de enseñanza secundaria. Se determinaron los materiales y recursos instruccionales que más se emplean en las aulas de ciencias y se evaluaron los canales sensoriales implicados en dichos materiales y recursos. Se comparó la presencia de preferencias sensoriales VARK en los alumnos con los canales sensoriales involucrados en los recursos instruccionales ofertados en ciencias. Resultados: Los hallazgos sugieren que hay un exceso de oferta del canal V (visual) pero un defecto de oferta del canal K (cinestésico), siempre en relación con su presencia respectiva en las preferencias de los estudiantes. Discusión: El desequilibrio encontrado en el canal K, que está muy implicado en actividades propias de la ciencia (actividades prácticas) podría ser una de las causas de los bajos rendimientos en las asignaturas científicas.
Organización del aula inclusiva: ¿Cómo diferenciar las estructuras para lograr prácticas educativas más efectivas?
Authors: Sanahuja Ribés Aida , Moliner García Odet , Moliner Miravet Lidón
Published: October 2020

Resulta un verdadero desafío para el profesorado gestionar la diversidad presente en las aulas desde un enfoque inclusivo. El objetivo general de este estudio es indagar sobre cómo se organizan las aulas inclusivas para desarrollar prácticas más efectivas. Se presenta un estudio de casos múltiples de tres aulas de educación primaria españolas que trabajan siguiendo el modelo inclusivo. La entrevista, un inventario de prácticas de aula, la observación no participante y el análisis documental han sido los métodos de recogida de datos utilizados en esta investigación. El análisis de datos se ha realizado mediante la herramienta ATLAS.ti. Los resultados muestran posibles formas de diferenciación pedagógica: gestión de los agrupamientos, las modalidades de trabajo, el tiempo, el espacio y los recursos. Se aportan las implicaciones prácticas que ayudan a materializar los principios teóricos de la educación inclusiva. A modo de conclusión: 1) la combinación de diferentes agrupamientos permite responder a los diferentes estilos de aprendizaje y estimula el apoyo entre iguales; 2) la flexibilidad de tiempos y espacios favorece la respuesta a la diversidad y 3) un uso óptimo de los recursos ordinarios favorece la articulación de un aula inclusiva.
Revolution and Roses: The Voice and Aesthetic of Sarah Mapps Douglass
Authors: Morgan Tabitha A.
Published: October 2020

Philadelphian Sarah Mapps Douglass has been recognized as a powerful figure in the nineteenth-century fight for African American rights and liberation, yet she is often forgotten for her activist work in the arts. Utilizing both feminist tactics and upper-class traditions, Douglass became a revolutionary figure for Black women’s cultural practice and social justice reform.
Slicing Up the Utopian Pie
Authors: Dutton Jacqueline
Published: October 2020

This article merges the intellectual concept of utopia and the material culture of the pie as a metaphor to explore the relative hegemony of Judeo-Christian (and/or Anglo-European) utopian literature and criticism. Citing Lyman Tower Sargent's contributions to opening up scholarship on comparative utopias, the author underscores his influence on her own thinking and publications on the topic. The study traces parallels between intellectual and material cultures, especially in French, Japanese, and Indigenous Australian contexts. In conclusion, it suggests that contemporary transformations in writing and reading utopias should encourage greater recognition of intercultural imaginaries of the ideal.
“A Number of Beginnings”: The n Phases of Utopian Genres
Authors: Prettyman Gib
Published: October 2020

This essay honors Lyman Tower Sargent's cumulative work on utopian genres by offering a brief provocation about genre in general. Beneath the evolving faces of utopianism, it proposes that we focus on a different aspect of genre: the indeterminate number n of embodied labors at particular sites and times where people applied the conceptual and material tools at hand to the work of interacting with particular aspects of lived experience. It argues that much of the work of genre—the work of genre deploying, genre undoing, genre becoming, or genre aspiring to become—happens at unique sites of labor, past, present, and future. Following McKenzie Wark, it refers to this as a labor point of view toward genre.
Guns Under the Table: Kim Stanley Robinson and the Transition to Utopia
Authors: Milner Andrew
Published: October 2020

Kim Stanley Robinson is a declared eco-socialist and arguably the most distinguished acolyte of Fredric Jameson, America's leading Marxist literary critic. Robinson's Mars trilogy develops a detailed account of three political revolutions. Robinson explains that this was a deliberate choice on his part, because he felt that in his first utopian novel, Pacific Edge, he “dodged the necessity of revolution.” He describes Antarctica and The Years of Rice and Salt as his next utopian novels, but these, too, dodge the “necessity of revolution,” the first by substituting science for politics, the second by projecting an alternative history into an alternative future. In the Science in the Capital trilogy, politics becomes paramount, and it continues to be so in his more recent fiction. This article will explore how Robinson negotiates the transition to utopia in his later work, from Forty Signs of Rain through to New York 2140 and Red Moon.

Del hijo único al segundo hijo políticas demográficas en China y sus consecuencias sobre la población
Authors: Zamora López Francisco , Rodríguez Veiga Cristina
Published: October 2020

Desde la aplicación de la política del hijo único en 1979 hasta la ya anunciada posible desaparición de cualquier mención a un número máximo de hijos en marzo de 2020, los dirigentes chinos han ido adaptando la natalidad de la población china a las supuestas necesidades de su demografía. Se analiza si la política del hijo único incidió sobre el descenso de la fecundidad en China, así como otras consecuencias que habitualmente se le atribuyen: descenso del crecimiento poblacional, envejecimiento acelerado, incremento del desequilibrio por sexo y desequilibrio del mercado matrimonial. Igualmente se intenta averiguar lo que hubiera pasado de no aplicarse esta política del hijo único. Por último, se procura valorar cuáles serían las consecuencias sobre la situación demográfica actual china de la previsible desaparición de la limitación del número máximo de hijos por pareja.
