Authors: Marcham Hannah , Tavassoli Teresa
Published: April 2024

Importance: Differences in sensory reactivity are a core feature of autism; however, more remains to be learned about their role in classroom learning.

Objective: To use direct observational measures to investigate whether there is a link between sensory reactivity differences and classroom behaviors of autistic children.

Design: Correlational study.

Setting: Two special educational needs schools.

Participants: Children with a clinical diagnosis of autism, ages 5 to 18 yr (N = 53).

Outcomes and Measures: Sensory reactivity differences were assessed with the Sensory Assessment for Neurodevelopmental Differences. Classroom behaviors were measured using the Behavior Assessment for Children–Second Edition Student Observation System.

Results: Total sensory reactivity differences were correlated positively with behaviors that impede learning (r = .31, p < .05) and negatively with behaviors that facilitate learning (r = −.38, p < .05). Hyporeactivity differences were correlated positively with behaviors that impede learning (r = .28, p < .05) and negatively with behaviors that facilitate learning (r = −.31, p < .05). Hyperreactivity and sensory-seeking differences were not significantly correlated with behavior.

Conclusions and Relevance: Results suggest a link between sensory reactivity differences and classroom behaviors, highlighting a need for further research using observational measures in special education settings.

Plain-Language Summary: Differences in hyporeactivity for children with autism may play a bigger role in classroom behavior and learning than previous literature has suggested. This has implications in occupational therapy practice for how to tailor support for children with hyporeactivity differences.

Inclusion of bedrock vadose zone in dynamic global vegetation models is key for simulating vegetation structure and function

Published: April 2024

Abstract. Across many upland environments, soils are thin and plant roots extend into fractured and weathered bedrock where moisture and nutrients can be obtained. Root water extraction from unsaturated weathered bedrock is widespread and, in many environments, can explain gradients in vegetation community composition, transpiration, and plant sensitivity to climate. Despite increasing recognition of its importance, the “rock moisture” reservoir is rarely incorporated into vegetation and Earth system models. Here, we address this weakness in a widely used dynamic global vegetation model (DGVM; LPJ-GUESS). First, we use a water flux-tracking deficit approach to more accurately parameterize plant-accessible water storage capacity across the contiguous United States, which critically includes the water in bedrock below depths typically prescribed by soil databases. Secondly, we exploit field-based knowledge of contrasting plant-available water storage capacity in weathered bedrock across two bedrock types in the Northern California Coast Ranges as a detailed case study. For the case study in Northern California, climate and soil water storage capacity are similar at the two study areas, but the site with thick weathered bedrock and ample rock moisture supports a temperate mixed broadleaf–needleleaf evergreen forest, whereas the site with thin weathered bedrock and limited rock moisture supports an oak savanna. The distinct biomes, seasonality and magnitude of transpiration and primary productivity, and baseflow magnitudes only emerge from the DGVM when a new and simple subsurface storage structure and hydrology scheme is parameterized with storage capacities extending beyond the soil into the bedrock. Across the contiguous United States, the updated hydrology and subsurface storage improve annual evapotranspiration estimates as compared to satellite-derived products, particularly in seasonally dry regions. Specifically, the updated hydrology and subsurface storage allow for enhanced evapotranspiration through the dry season that better matches actual evapotranspiration patterns. While we made changes to both the subsurface water storage capacity and the hydrology, the most important impacts on model performance derive from changes to the subsurface water storage capacity. Our findings highlight the importance of rock moisture in explaining and predicting vegetation structure and function, particularly in seasonally dry climates. These findings motivate efforts to better incorporate the rock moisture reservoir into vegetation, climate, and landscape evolution models.

Published: April 2024

Abstract. Northern latitudes have been significantly impacted by recent climate warming, which has increased the probability of experiencing extreme weather events. To comprehensively understand hydroclimate change and reconstruct hydroclimatic anomalies such as drought periods, appropriate proxy records reaching further back in time beyond meteorological measurements are needed. Here we present a 220-year (2015–1790 CE), continuous, stable oxygen isotope record of diatoms (δ18Odiatom) from Lake Khamra (59.99° N, 112.98° E) in eastern Siberia, an area highly sensitive to climate change and for which there is a demand for palaeohydrological data. This high-resolution proxy record was obtained from a 210Pb–137Cs-dated sediment short core and analysed to reconstruct hydroclimate variability at a sub-decadal scale. The interpretation of the δ18Odiatom record is supported by meteorological data, modern isotope hydrology and geochemical analyses of the same sediment, which is indicative of the conditions in the lake and catchment. A comparison with meteorological data going back to 1930 CE revealed that the δ18Odiatom record of Lake Khamra is primarily influenced by regional precipitation changes rather than the air temperature. We identified winter precipitation, which enters the lake as isotopically depleted snowmelt water, as the key process impacting the diatom isotope variability. We related the overall depletion of δ18Odiatom in recent decades to an observed increase in winter precipitation in the area, likely associated with the global air temperature rise, Arctic sea ice retreat and increased moisture transport inland. Available palaeoclimate proxy records, including a fire reconstruction for the same lake, support the idea that the new record is a valuable hydroclimate proxy that is indicative of precipitation deficits and excludes solar insolation and air temperature as primary driving forces, even before the first meteorological recordings. We propose two possible hydroclimatic anomalies that were detected in the Lake Khamra δ18Odiatom record: one at the beginning of the 19th century and a second prominent event in the 1950s. Both are interpreted as prolonged dry periods associated with enriched δ18Odiatom values likely caused by reduced winter precipitation, which coincide with phases of reconstructed severe wildfires in the region. Despite the apparent pristine lake area, we observed a three- to fourfold increase in mercury concentrations and accumulation rates within the sediment record since the early 20th century, which is partly attributed to human air pollution.

Published: April 2024

Abstract. Warming, ocean acidification, and deoxygenation are increasingly putting pressure on marine ecosystems. At the same time, thawing permafrost and decomposing hydrates in Arctic shelf seas may release large amounts of methane (CH4) into the water column, which could accelerate local ocean acidification and contribute to climate change. The key parameters to observing and understanding these complex processes and feedback mechanisms are vastly undersampled throughout the oceans. We developed carbon dioxide (CO2) and CH4 gliders, including standard operational procedures with the goal that CO2 and CH4 measurements become more common for glider operations. The Seagliders with integrated Contros HydroC CO2 or CH4 sensors also include conductivity, temperature, depth, oxygen, chlorophyll-a, backscatter, and fluorescent dissolved organic matter sensors. Communication via satellite allows for near-real time data transmission, sensor adjustments, and adaptive sampling. Several sea trials with the CO2 Seaglider in the Gulf of Alaska and data evaluation with discrete water and underway samples suggest near ‘weather quality’ CO2 data as defined by the Global Ocean Acidification Network. A winter mission in Resurrection Bay, Alaska provides first insights into the water column inorganic carbon dynamics during this otherwise undersampled season. The CH4 Seaglider passed its flight trials in Resurrection Bay and is ready to be deployed in an area with greater CH4 activity. Both sensing systems are available to the science community through the industry partners (Advanced Offshore Operations and -4H-JENA) of this project.
Measurement of greenhouse gas fluxes in agricultural soils with a flexible, open-design automated system

Published: April 2024

Abstract. Over the last decades and due to the current climate change situation, the study of the impacts of human activities on climate has reached great importance, being agriculture one of the main sources of soil greenhouse gas. There are different techniques to quantify the soil gas fluxes, such as micrometeorological techniques or chamber techniques, being the last one capable to assess different treatment at the same site. Manual chambers are the most common one. However, due to the low sampling frequency, this approach cannot resolve short-term emission events, like fertilization or rewetting. For this reason, automated chamber systems are an opportunity to improve soil gas flux determination, but their distribution is still scarce due to the cost and challenging technical implementation. The objective of this study was to develop an automated chamber system for agricultural systems under Mediterranean conditions and compare measured GHG flux rates to those derived using manual chambers. A comparison between manual and automated chamber systems was conducted to evaluate the soil gas fluxes obtained by the automated system. Moreover, over a period of one month the soil gas fluxes were determined by both systems to compare their capabilities to capture the temporal variability of soil gas emissions. The automated system reported higher soil GHG fluxes compared to the manual chamber system. Additionally, the higher sampling frequency of the automated chamber system allowed for the capture of daily flux variations, resulting in a more accurate estimation of cumulative soil gas emissions. The study emphasises the importance of chamber dimension and shape, as well as sampling frequency, in the development of chamber systems, especially when using the manual chamber system.

Abstract. We determine the global emission distribution of the potent greenhouse gas sulfur hexafluoride (SF6) for the period 2005–2021 using inverse modeling. The inversion is based on 50-day backward simulations with the Lagrangian Particle Dispersion Model (LPDM) FLEXPART and on a comprehensive observation data set of SF6 mole fractions, in which we combine continuous with flask measurements sampled at fixed surface locations, and observations from aircraft and ship campaigns. We use a global distribution-based (GDB) approach to determine baseline mole fractions directly from global SF6 mole fraction fields at the termination points of the backward trajectories. We compute these fields by performing an atmospheric SF6 re-analysis, assimilating global SF6 observations into modeled global three-dimensional mole fraction fields. Our inversion results are in excellent agreement with several regional inversion studies in the USA, Europe, and China. We find that (1) annual U.S. SF6 emissions strongly decreased from 1.25 Gg in 2005 to 0.48 Gg in 2021, however, they were on average twice as high as the reported emissions to the United Nations. (2) SF6 emissions from EU countries show an average decreasing trend of -0.006 Gg/yr during the period 2005 to 2021, including a substantial drop in 2018. This drop is likely a direct result of the EU’s F-gas regulation 517/2014, which bans the use of SF6 for recycling magnesium die-casting alloys from 2018 and requires leak detection systems for electrical switch gear. (3) Chinese annual emissions grew from 1.28 Gg in 2005 to 5.16 Gg in 2021, with a trend of 0.21 Gg/yr, which is even higher than the average global total emission trend of 0.20 Gg/yr. (4) National reports for the USA, Europe, and China all underestimated their SF6 emissions. (5) The global total SF6 emissions are captured well by the inversion, however, results are sensitive to the a priori emission estimates, given that substantial biases of these estimates in regions poorly covered by the measurement network (e.g. Africa, South America) can be improved but not entirely corrected. (6) Monthly inversions indicate that SF6 emissions in the Northern Hemisphere were on average higher in summer than in winter throughout the study period.

Abstract. The planetary boundary layer (PBL) over the Tibetan Plateau (TP) exerts a significant influence on regional and global climate, while its vertical structures of turbulence and evolution features remain poorly understood, largely due to the scarcity of observation. This study examines the vertical profile and daytime variation of turbulence dissipation rate (ε) in the PBL over the TP using the high-resolution (6 min and 120 m) measurements from the radar wind profiler (RWP) network, combined with the hourly data from the ERA5 reanalysis. Observational analyses show that the magnitude of ε below 3 km under all-sky conditions exhibits large spatial discrepancy over the six RWP sites over the TP. Particularly, the values of ε at Minfeng and Jiuquan over the northern TP and Dingri over the southern TP are roughly an order of magnitude greater than those at Lijiang, Ganzi and Hongyuan over the eastern TP. This could be partially attributed to the difference of land cover across the six RWP sites. In terms of the diurnal variation, ε rapidly intensifies from 0900 local standard time (LST) to 1400 LST, and then gradually levels off in the late afternoon. Under clear-sky conditions, both ε and planetary boundary layer height (zi) are greater, compared with cloudy-sky conditions. This reveals that clouds would suppress the turbulence development and deduce zi. In the lower PBL (0.2<z / zi <0.5, where z is the height above ground level), the dominant influential factor for the development of turbulence is the surface-air temperature difference (Ts – Ta). By comparison, in the upper PBL (0.6< z / zi <1.0), both the and vertical wind shear (VWS) affect the development of turbulence. Above the PBL (1.0< z / zi <2.0), the shear production resulting from VWS dominates the variation of turbulence. Under cloudy-sky conditions, clouds are found to decrease the surface total solar radiation, thereby reducing Ts – Ta and surface sensible heat flux. This weakened sensible heat flux tends to inhibit the turbulent motion within PBL especially in the lower PBL and decrease the growth rate of zi. On the other hand, the strong VWS induced by clouds enhances the turbulence above the PBL. The findings obtained here underscore the importance of RWP network in revealing the fine-scale structures of the PBL over the TP and gaining new insight into the PBL evolution.

Abstract. Today’s Arctic is characterized by a lengthening of the sea ice melt season, but also by fast and at times unseasonal melt events. Such anomalous melt cases have been identified in Pacific and Atlantic Arctic sector sea ice studies. Through observational analyses, we document an unprecedented, simultaneous marginal ice zone melt event in the Bering Sea and Labrador Sea in March of 2023. Taken independently, variability in the cold season ice edge at synoptic time scales is common. However, such anomalous, short-term ice loss over either region during the climatological sea ice maxima is uncommon, and the tandem ice loss that occurred qualifies this as a rare event. The atmospheric setting that supported the unseasonal melt events was preceded by a sudden stratospheric warming event that, along with ongoing La Niña teleconnections, led to positive tropospheric height anomalies across much of the Arctic and the development of anomalous mid-troposphere ridges over the ice loss regions. These large-scale anticyclonic centers funneled extremely warm and moist airstreams onto the ice causing melt. Further analysis identified the presence of atmospheric rivers within these warm airstreams whose characteristics likely contributed to this bi-regional ice melt event. Whether such a confluence of anomalous wintertime events associated with troposphere-stratosphere coupling may occur more often in a warming Arctic remains a research area ripe for further exploration.
The movement of atmospheric blocking systems: can we still assume quasi-stationarity?
Authors: van Mourik Jonna , de Vries Hylke , Baatsen Michiel
Published: April 2024

Abstract. The quasi-stationary behaviour of atmospheric blocking is studied using a Lagrangian framework that enables the tracking of blocks in space and time. By combining a blocking index based on geopotential height with a lagrangian tracking algorithm, we investigate the characteristics of atmospheric blocking events for different zonal propagation velocities and their impacts on surface temperatures within the retuned EC-Earth3 global climate model. We observe that blocking events 5 can portray a large variety of propagation velocities. Distinct differences are found between the behaviour of eastward-moving blocks and westward-moving blocks, both in size and in spatial distribution. Although the size of blocks is of bigger importance for the temperature anomalies, the propagation velocity has an influence on the strength of the temperature anomalies in winter, due to the slower mechanism of air advection in winter, compared to diabatic heating in summer. In summer, the propagation velocity primarily influences the positioning of temperature anomalies relative to the centre of the blocking system. These 10 findings highlight the complex interactions between size, propagation velocity, and other blocking attributes, and their influence on temperature anomalies. Further research is warranted to explore regional differences in blocking behaviour and impact, as well as how atmospheric blocking and associated temperature anomalies may evolve under future climate conditions.
A hybrid-grid global model for the estimation of atmospheric weighted mean temperature considering time-varying lapse rate in GNSS precipitable water vapor retrieval

Published: April 2024

Abstract. The atmospheric weighted mean temperature (Tm) is a key parameter in global navigation satellite system (GNSS) water vapor retrieval and can convert the zenith wet delay (ZWD) into precipitable water vapor (PWV). However, there are some shortcomings in the existing Tm models, such as the detailed time-varying lapse rate not being considered. Additionally, the spatiotemporal characteristics of Tm need to be further refined. Therefore, we developed a new global high-precision and high-spatiotemporal-resolution Tm model considering time-varying lapse rate using the latest European Centre for Medium-Range Weather Forecasts ReAnalysis 5 (ERA5) atmospheric reanalysis data. Firstly, a global multidimensional Tm lapse rate model (NGGTm-H model) was developed using the sliding window algorithm. Secondly, the daily variation characteristics of Tm and its relationships with geographical situation were investigated. Finally, a hybrid-grid global Tm model considering time-varying lapse rate (NGGTm model) was developed. To verify the effectiveness of the proposed model, the NGGTm model was compared with the Bevis and GPT3 models using the Tm data recorded at 378 radiosonde stations in 2017 and the surface grid Tm data calculated from the ERA5 reanalysis data. The results show that taking the surface grid Tm data of ERA5 as reference values, the average root mean square error (RMSE) value predicted by the NGGTm model was 2.84 K, which was higher with 0.50 K, 0.18 K and 0.06 K than those of the Bevis, GPT3-5 and GPT3-1 models, respectively. Meanwhile, taking the Tm data from the radiosonde stations as the reference values, the mean bias and RMSE of the NGGTm model were 0.10 K and 3.30 K, respectively, which exhibit the best accuracy and stability among the Bevis, GPT3-5 and GPT3-1 models.

Published: April 2024

Abstract. This study presents the first detailed data on calcareous nannofossil assemblages from the Sabiñánigo Sandstone Formation in the Jaca Basin (central south Pyrenees). This formation is mainly composed of deltaic and outer-shelf sediments. These siliciclastic deposits contain nannofossil assemblages that are moderately to well-preserved, particularly in fine-grained levels. They contain a calcareous nannofossil assemblage dominated by the species Cyclicargolithus floridanus, Coccolithus pelagicus, Coccolithus formosus, Clausicoccus fenestratus, Zygrhablithus bijugatus, and several species of Sphenolithus and Chiasmolithus. The biostratigraphic results enabled the characterization of the Middle Eocene biohorizons, based on global stratigraphic scales and the improvement of the temporal correlation and lateral evolution of this basin's deposits. The sedimentary sequence of the Sabiñánigo Sandstone was deposited during the Middle Eocene, between the upper part of biozone NP16 and the base of NP17, in the Bartonian. The calcareous nannoplankton assemblage suggests warm and oligotrophic surface waters for the Bartonian interval in the Jaca Basin.
Demonstrating the use of UNSEEN climate data for hydrological applications: case studies for extreme floods and droughts in England

Published: April 2024

Abstract. Meteorological and hydrological hazards present challenges to people and ecosystems worldwide, but the limited length of observational data means that the possible extreme range is not fully understood. Here, a large ensemble of climate model data is combined with a simple grid-based hydrological model, to assess unprecedented but plausible hydrological extremes in the current climate across England. Two case studies are selected—dry (Summer 2022) and wet (Autumn 2023)—with the hydrological model initialised from known conditions then run forward for several months using the large climate ensemble. The modelling chain provides a large set of plausible events including extremes outside the range from use of observed data, with the lowest flows around 28 % lower on average for the Summer 2022 drought study and the highest flows around 42 % higher on average for the Autumn 2023 flood study. The temporal evolution and spatial dependence of extremes is investigated, including the potential time-scale of recovery of flows to normal and the chance of persistent extremes. Being able to plan for such events could help improve the resilience of water supply systems to drought, and improve flood risk management and incident response.

Introducción: Los síntomas del cáncer de mama y los efectos secundarios del tratamiento pueden afectar significativamente a diferentes áreas funcionales de las mujeres. Objetivo: examinar la calidad de vida de mujeres con cáncer de mama. Método: la muestra estuvo compuesta por 240 mujeres de entre 30 y 68 años (M=52; DT=8,68). Aproximadamente el 50% se había sometido a una mastectomía, mientras que al 40% se le había realizado una reconstrucción mamaria. Un cuestionario estructurado constaba de datos sociodemográficos, SQOL-F, EORTC QLQ-C30 y EORTC QLQ-BR23. Resultados: Los resultados sugieren que nuestros pacientes con BC tenían una menor calidad de vida y más dificultades financieras que en la mayoría de los otros estudios, lo que implica algunas diferencias culturales o del sistema de salud. No someterse a una mastectomía se asoció con una mejor calidad de vida sexual, salud global y funcionamiento físico. Por el contrario, las mujeres que se sometieron a mastectomía informaron problemas de imagen corporal y funcionamiento sexual, con síntomas mamarios más prominentes. La reconstrucción se relacionó con una menor calidad de vida y ninguna mejora en la imagen corporal. Conclusiones: La calidad de vida sexual se relacionó principalmente con el estado de salud global, el funcionamiento emocional, los efectos secundarios del tratamiento y la imagen corporal. El funcionamiento emocional y los efectos secundarios fueron predictores importantes de la calidad de vida sexual, mientras que el funcionamiento sexual deteriorado se asoció con una imagen corporal distorsionada. Estos hallazgos pueden servir como guía para formular intervenciones destinadas a mejorar la calidad de vida.

Published: April 2024

Introducción: los meningiomas forman el 27% de los tumores de encéfalo en población adulta. La radioterapia es uno de los tratamientos para tumores primarios del SNC más efectivos, en el cual se administran altas dosis de radiación que destruye el ADN de las células cancerosas para detener su multiplicación o lentificar su crecimiento. Para este tratamiento es necesaria la inmovilización del paciente, que se asegura por medio de máscaras termoplásticas que fijan al paciente a la camilla del acelerador lineal. Este tipo de inmovilización ha representado una incidencia de ansiedad significativa previa al tratamiento y durante el mismo, puede causar niveles altos de estrés, miedo, malestar físico, dolor e incluso claustrofobia. Tomando en cuenta estos aspectos, como preparación psicológica para el tratamiento se sugiere ofrecer información clara previa y durante la simulación, identificar a los pacientes con niveles altos de ansiedad, y brindar estrategias cognitivas y conductuales para regular la misma. Objetivo: Describir un reporte de caso de preparación para radioterapia en SNC. Método: Se presenta el caso de una mujer de 61 años de edad que fue referida a psico-oncología con el objetivo de la preparación psicológica para radioterapia en SNC. El motivo de la referencia a psico-oncología fue evitar la sedación durante la radioterapia debido a los altos niveles de ansiedad que presentaba la paciente. Se realizaron dos sesiones de preparación psicológica en donde se incluyeron estrategias psicoeducativas, de desensibilización sistemática y respiración diafragmática. Resultados: La paciente disminuyó el reporte subjetivo de ansiedad, logró terminar las 25 sesiones de radioterapia sin necesidad de sedación. Conclusión: La preparación psicológica utilizada en esta paciente fue efectiva para disminuir ansiedad. Es importante realizar estudios aleatorizados y controlados para conocer realmente la efectividad.

The Effectiveness of Utilizing Invalid Registrations - Daejeon District Court Decision 2016Na105785 Decided December 13, 2016(which is The appellate judgment of Supreme Court Decision 2017Da204629 Decided July 28, 2022), Supreme Court Decision 2009Da4787 Decided May 28 -

Published: April 2024

Traditional precedents and the prevailing view hold that regarding the usefulness of invalid registrations, if there is a third party with an interest in the registration before the agreement on its usefulness, the agreement is not effective in relation to that third party, and within that scope, the registration made useful is considered invalid as it does not correspond to the actual legal relationships.
The decisions in question judged that in cases where a provisional registration, which is invalid, has been utilized to complete a final registration or a provisional transfer registration, (a) the utilization of the registration cannot be claimed against a third party with an interest in the registration, such as a provisional seizure creditor, but (b) among the parties to the agreement of utilization, the validity of the utilization agreement and the registration made useful can still be claimed. However, in the situations addressed by these decisions, the provisional seizure creditor, who is a third party with an interest in the registration, can only request the cancellation of such provisional registrations on behalf of the debtor (one of the parties to the utilization agreement) and therefore, cannot claim the invalidity of the utilization agreement and the registration made useful against the parties to the invalid registration utilization who cannot oppose them.
However, the conclusion of (b) is incorrect, and therefore, the conclusions of the decisions in question cannot be considered correct. That is, the conclusion that in the presence of a third party with an interest in the registration, the agreement of utilization and the registration made useful are invalid only in relation to that third party, and the validity of the utilization agreement and the registration made useful can still be claimed among the parties to the utilization is not acceptable as it acknowledges the relative effect of real rights. When there is a third party with an interest in the registration, the utilization of an invalid registration should not be recognized. It is not that the validity of the agreement of utilization and the useful registration “cannot be claimed only against the third party with an interest in the registration” and “within that scope,” but rather, “in cases where there is a third party with an interest in the registration,” the agreement of utilization and the useful registration, not corresponding to the actual legal relationships, should be considered “invalid against everyone.” Here, “everyone” includes the parties to the agreement of utilization (the counterpart).

Bisher wurden die zivilrechtlichen Regelungen über Stiftungen in den §§ 80 ff. BGB a.F. durch zivilrechtliche Regelungen in den Landesstiftungsgesetzen ergänzt. Dieser Nebeneinander von Bundesrecht und Landesrecht verursacht Streitfragen und Rechtsunsicherheit bei Stiftern und Stiftungen. Durch die Reform wird erwartet, die sich daraus ergebende Rechtsunsicherheit zu beseitigen, Streitfragen zu klären und das Stiftungsrecht zu vereinheitlichen. Infolgedessen treten 36 weitgehend neugefasste Regelungen an die Stelle der bisherigen 9 Paragrafen der §§ 80 bis 88 BGB a.F. Insbesondere in Bezug auf das Vermögen der Stiftung enthält das BGB n.F. die begriffliche Regelung über das Stiftungsvermögen (§83b BGB n.F.) und die Regelung zur Verwaltung des Grundstockvermögens (§83c BGB n.F.). Während des langen Reformprozesses in Deutschland stießen die Entwürfe jedoch auf heftige Kritik und warfen zahlreiche neue Fragen auf. Die Untersuchung der Hintergründe dieser Kritik und Probleme sowie wie Deutschland damit umgeht und sie bewältigt, ist auch für das koreanische Stiftungsrecht aufschlussreich, da sich aus rechtshistorischem Hintergrund die Ähnlichkeit der Regelungen und der dogmatischen Begründungen in den beiden Ländern ergibt und dies einen guten Vergleichsgegenstand geben kann. In Zukunft sollte Korea ebenfalls aggressiv die Definition und Verwaltung des Stiftungsvermögen, die Stärkung der Leistungsfähigkeit der Stiftung und die Vereinheitlichung der Begriffe überprüfen.

В каждом государстве процесс развития медиакоммуникаций происходит по-разному. Развитие информационных технологий и использование их средствами массовой информации меняют аудиторию потребителей информации.  А любой потребитель информации в конечном счете является электоральной единицей в политической системе любого государства. Внедрение искусственного интеллекта в систему создания информации российским учеными еще не исследовался. Цель исследования – определить и описать основные результаты, полученные СМИ в Китайской Народной республике с переходом на иной уровень использования технологий. В результате исследования были выявлены тенденции развития медиакоммуникации КНР. Анализ данных о развитии интернет-платформ и структурах СМИ в КНР позволяет сделать вывод, что эпоха медиаконвергенции как способа привлечения аудитории к потреблению информации заканчивается. То, что в России, западных странах или странах Северной Америки только упоминается как предполагаемый вектор развития СМИ, в КНР уже внедрено. Речь идет о феномене омнимедиа. Самая важная, по мнению авторов, тенденция – это использование нейросетей, которые являются платформой омнимедиа. Опыт использования КНР интернет-платформ важен для понимания того, как может развиваться медиаконвергенция в России. В то же время, традиционная печатная продукция является неотъемлемым атрибутом Китайского общества.
Языковые контакты и нативизация фразеологических единиц в ЮАР
Authors: Бочарова Эмилия Александровна
Published: April 2024

Рассмотрена специфика фразеологических единиц в процессе нативизации, под которой понимается процесс адаптации к нормам местных языков и культур. Целью исследования является выявление специфики нативизации фразеологических единиц вследствие контактного взаимодействия. Исследование проведено на основе сравнительно-сопоставительного анализа фразеологического фонда британского английского языка и территориального варианта английского языка в ЮАР. Путем сочетания методов индукции и дедукции, фразеологической идентификации и компонентного анализа выявлены уникальные свойства фразеологического фонда английского языка, функционирующего на территории ЮАР, подверженного влиянию интерференционных процессов со стороны местных лингвокультур: высокопродуктивные вкрапления лексем автохтонных языков ЮАР, наиболее продуктивными из которых являются языки зулу, хоса и африкаанс; тенденция к симплификации грамматической структуры фразеологизмов, что проявляется, в большей степени, в опущении артиклей.

Breast cancer has been predicted to impact over 2.3 million women annually, with 685,000 deaths occurring out of this condition globally. Breast cancer initially appears in the epithelial cells of channels or lobules of breast glandular tissue whereas less commonly from the basal cells outer layer. Even though some inhibitors have demonstrated anti-breast cancer cell activity, resistance to existing inhibitors and their severe side effects have forced to develop new derivatives. Coumarin nucleoside derivatives were therefore studied in silico, and their effectiveness against cancer cells was found. The studies consisted of ADMET properties, target prediction, MD stimulation, and drug-likeliness characterises. Out of the 12 compounds studied, compounds 2 and 4 were found most potent with binding energy (-7.091 and -7.018kcal/mol respectively). The standard erlotinib (AQ4) with a binding energy of -8.614 kcal/mol.
