Impact of Asian aerosols on the summer monsoon strongly modulated by regional precipitation biases
Authors: Liu Zhen , Bollasina Massimo A. , Wilcox Laura J.
Published: June 2024

Abstract. Reliable attribution of Asian summer monsoon variations to aerosol forcing is critical to reducing uncertainties in future projections of regional water availability, which is of utmost importance for risk management and adaptation planning in this densely populated region. Yet, simulating the monsoon remains a challenge for climate models that suffer from long-standing biases, undermining their reliability in attributing anthropogenically forced changes. We analyze a suite of climate model experiments to identify a link between model biases and monsoon responses to Asian aerosols and associated physical mechanisms, including the role of large-scale circulation changes. The aerosol impact on monsoon precipitation and circulation is strongly influenced by a model's ability to simulate the spatio-temporal variability in the climatological monsoon winds, clouds, and precipitation across Asia, which modulates the magnitude and efficacy of aerosol–cloud–precipitation interactions, an important component of the total aerosol response. There is a strong interplay between South Asia and East Asia monsoon precipitation biases and their relative predominance in driving the overall monsoon response. We found a striking contrast between the early- and late-summer aerosol-driven changes ascribable to opposite signs and seasonal evolution of the biases in the two regions. A realistic simulation of the evolution of the large-scale atmospheric circulation is crucial to realize the full extent of the aerosol impact over Asia. These findings provide important implications for better understanding and constraining the diversity and inconsistencies of model responses to aerosol changes over Asia in historical simulations and future projections.

Abstract. Accurate cloud quantification is essential in climate change research. In this work, we construct an automated computer vision framework by synergistically incorporating deep neural networks and finite-sector clustering to achieve robust whole-sky image-based cloud classification, adaptive segmentation and recognition under intricate illumination dynamics. A bespoke YOLOv8 (You Only Look Once 8) architecture attains over 95 % categorical precision across four archetypal cloud varieties curated from extensive annual observations (2020) at a Tibetan highland station. Tailor-made segmentation strategies adapted to distinct cloud configurations, allied with illumination-invariant image enhancement algorithms, effectively eliminate solar interference and substantially boost quantitative performance even in illumination-adverse analysis scenarios. Compared with the traditional threshold analysis method, the cloud quantification accuracy calculated within the framework of this paper is significantly improved. Collectively, the methodological innovations provide an advanced solution to markedly escalate cloud quantification precision levels imperative for climate change research while offering a paradigm for cloud analytics transferable to various meteorological stations.
Technical note: An open-source, low-cost system for continuous monitoring of low nitrate concentrations in soil and open water

Published: June 2024

Abstract. Nitrate (NO3-), mainly leaching with soil porewater, is the primary nonpoint source pollutant of groundwater worldwide. Obtaining real-time information on nitrate levels in soils would allow for gaining a better understanding of the sources and transport dynamics of nitrate through the unsaturated zone. However, conventional nitrate detection techniques (e.g., soil sample analysis) necessitate costly, laboratory-grade equipment for analysis, along with human resources, resulting in a laborious and time-intensive procedure. These drawbacks raise the need to develop cost-effective and automated systems for in situ nitrate measurements in field conditions. This study presents the development of a low-cost, portable, automated system for field measurements of nitrate in soil porewater and open water bodies. The system is based on the spectrophotometric determination of nitrate using a single reagent. The system design and processing software are openly accessible, including a building guide, to allow duplicating or changing the system according to user-specific needs. Three field tests, conducted over 5 weeks, validated the system's measurement capabilities within the range of 0–10 ppm NO3-–N with a low RMSE of <0.2 ppm NO3-–N when comparing the results to standard laboratory nitrate analysis. Data derived from such a system allow for tracking of the temporal variation in soil nitrate, thus opening new possibilities for diverse soil and nutrient management studies.

Published: June 2024

Abstract. Accurate representation of croplands is essential for simulating terrestrial water, energy, and carbon fluxes over India because croplands constitute more than 50 % of the Indian land mass. Spring wheat and rice are the two major crops grown in India, covering more than 80 % of the agricultural land. The Community Land Model version 5 (CLM5) has significant errors in simulating the crop phenology, yield, and growing season lengths due to errors in the parameterizations of the crop module, leading to errors in carbon, water, and energy fluxes over these croplands. Our study aimed to improve the representation of these crops in CLM5. Unfortunately, the crop data necessary to calibrate and evaluate the models over the Indian region is not readily available. In this study, we used a comprehensive spring wheat and rice database that is the first of its kind for India and was created by digitizing historical observations. We used eight spring wheat sites and eight rice sites, and many of the sites have multiple growing seasons, bringing the tally up to nearly 20 growing seasons for each crop. We used this data to calibrate and improve the representation of the sowing dates, growing season, growth parameters, and base temperature in the CLM5 model. The modified CLM5 performed much better than the default model in simulating the crop phenology, yield, carbon, water, and energy fluxes when compared with the site-scale data and remote sensing observations. For instance, Pearson’s r for monthly LAI improved from 0.35 to 0.92, and monthly GPP improved from -0.46 to 0.79 compared to MODIS monthly data. The r values of the monthly sensible and latent heat fluxes improved from 0.76 and 0.52 to 0.9 and 0.88, respectively. Moreover, because of the corrected representation of the growing seasons, the seasonality of the simulated irrigation now matches the observations. This study demonstrates that global land models must use region-specific parameters rather than global parameters for accurately simulating vegetation processes and, eventually, land surface processes. Such improved land models will be a great asset in investigating global and regional-scale land-atmosphere interactions and developing future climate scenarios.
Causal relationships between vegetation productivity, water availability, and atmospheric dryness at the catchment scale

Published: June 2024

Abstract. This study explores the causal relationships between catchment water availability, vapor pressure deficit, and gross primary productivity across 341 catchments in the contiguous US. Seasonal climatic, hydrological, and vegetation characteristics were represented using the Horton index, ecological aridity index, evaporative fraction index, and carbon uptake efficiency. Statistical methods, including circularity statistics, correlation analysis, and causality tests, were employed to determine the complex interactions between catchment wetness, atmospheric dryness, and vegetation carbon uptake. The results revealed a maximum lag of two months in the intra-annual variability of catchment water supply-productivity and atmospheric water demand-productivity relationships, with hysteresis patterns varying with the catchment’s hydrological characteristics. In catchments not permanently under water-limited or energy-limited conditions, vegetation experiences hydrological stress during the peak growing period, coinciding with the highest gross primary productivity and carbon uptake efficiency being out of phase with Horton index and in phase with evaporative fraction index. Causality analysis highlights strong temporal continuity in GPP seasonal characteristics, with a cause-effect relationship between catchment water supply, atmospheric demand, and vegetation productivity spanning a maximum of two months. These findings underscore the need for a comprehensive functional framework that integrates catchment water supply, atmospheric demand, and vegetation productivity to enhance our understanding and predictive capabilities of ecosystem responses to climate change.

Published: June 2024

Abstract. The decreasing seawater pH trend associated with rising atmospheric CO2 levels adversely affects marine organisms and ecosystems, posing significant concerns for coastal fisheries and economies. Despite this, long-term pH variation in coastal waters remains poorly understood. This study investigates pH variability in the coastal waters of Korea over 11 years (2010–2020) and identifies the principal drivers of pH fluctuations. Unlike the persistent pH decline observed in open oceans and other coastal systems, Korean coastal waters showed no significant pH variation, suggesting local biogeochemical processes may exert a greater influence than atmospheric CO2. Analysis of environmental data (temperature, salinity, chlorophyll a, and dissolved oxygen (DO)) revealed a strong correlation between pH and DO. However, instances of pH changes exceeding those predicted by DO depletion indicate additional biogeochemical factors at play. As global seawater warms, reduced dissolved gases, including oxygen, are expected to cause further pH decline in coastal waters. This trend could critically impact Korean coastal waters, which support extensive aquaculture operations integral to the local and national economy. Therefore, high-frequency monitoring is essential to extend current time series and predict future water quality.
A simple physical model for glacial cycles

Published: June 2024

Abstract. Glacial cycles are the norm in Pleistocene climate variability. Models of varying degree of complexity have been used to answer the question of what causes the nonlinear response of the climate system to the periodic forcing from the Sun. At one end of the spectrum of complexity are comprehensive models which aim to represent all involved processes in a realistic manner. However, their high computational cost precludes their use in the ultra-long simulations needed. At the other end are conceptual models which are computationally less demanding but which generally lack a physical basis. Most of them yield good results in terms of capturing the shape and patterns of glacial cycles as indicated by the geological record, thus making it very difficult to identify the underlying mechanisms. Here we present a conceptual model that aims to physically represent the interaction between the climate and the Northern Hemisphere ice sheets while eliminating spatial dimensions in some of the fundamental ice-sheet thermodynamic and dynamic equations. To this end, we describe the Physical Adimensional Climate Cryosphere mOdel (PACCO) from its simplest to its most complex configuration. We discuss separately the implications of different fundamental mechanisms such as ice-sheet dynamics and thermodynamics, glacial isostatic adjustment and ice-sheet albedo aging for our model. We conclude that ice-sheet dynamics and a delayed isostatic response are sufficient to produce resonance around periodicities of 100 kyr, although the forcing has a spectrum concentrated around lower values. In addition, ice-sheet thermodynamics and ice aging separately enhance the model nonlinearities to provide 100 kyr periodicities in good agreement with reconstructions. However, we found that it is easier to reproduce the late Pleistocene glacial cycles using the simpler process of ice aging. Overall, PACCO is a valuable tool for analyzing the different hypotheses present in the literature.

Published: June 2024

Abstract. The interactions of metabolically active atmospheric microorganisms with cloud organic matter can alter the atmospheric carbon cycle. Upon deposition, atmospheric microorganisms can influence microbial communities in surface Earth systems. However, the metabolic activities of cultivable atmospheric microorganisms in settled habitats remain less understood. Here, we investigated exometabolites produced by typical bacterial and fungal species isolated from the urban atmosphere to elucidate their biogeochemical roles. Molecular compositions of exometabolites were analyzed using ultra-high resolution Fourier transform ion cyclotron resonance mass spectrometry. Annotation through the Kyoto Encyclopedia of Genes and Genomes database helped identify metabolic processes. Results showed that bacterial and fungal strains produce exometabolites with lower H/C and higher O/C ratios than consumed and resistant compounds. CHON compounds constituted over 50 % of the identified formulas of exometabolites. Bacterial exometabolites contained more abundant CHONS compounds (25.2 %), while fungal exometabolites were rich in CHO compounds (31.7 %). These microbial exometabolites predominantly comprised aliphatic/peptide-like and carboxyl-rich alicyclic molecules (CRAM-like). Significant variations in metabolites were observed among different strains. Bacteria showed a performance for amino acid synthesis, while fungi were more active in transcription and expression processes. Lipid metabolism, amino acid metabolism, and carbohydrate metabolism varied widely among bacterial strains, while fungi exhibited marked differences in carbohydrate metabolism and secondary metabolism. This comprehensive examination of metabolite characteristics at the molecular level for typical culturable airborne microorganisms enhances our understanding of their potential metabolic activities at air-land/water interfaces. These insights are pivotal for assessing the biogeochemical impacts of atmospheric microorganisms following their deposition.

Abstract. In response to the growing societal awareness of the critical role of healthy soils, there has been an increasing demand for accurate and high-resolution soil information to inform national policies and support sustainable land management decisions. Despite advancements in digital soil mapping and initiatives like GlobalSoilMap, quantifying soil variability and its uncertainty across space, depth and time remains a challenge. Therefore, maps of key soil properties are often still missing on a national scale, which is also the case in the Netherlands. To meet this challenge and fill this data gap, we introduce BIS-4D, a high-resolution soil modeling and mapping platform for the Netherlands. BIS-4D delivers maps of soil texture (clay, silt and sand content), bulk density, pH, total nitrogen, oxalate-extractable phosphorus, cation exchange capacity and their uncertainties at 25 m resolution between 0 and 2 m depth in 3D space. Additionally, it provides maps of soil organic matter and its uncertainty in 3D space and time between 1953 and 2023 at the same resolution and depth range. The statistical model uses machine learning informed by soil observations amounting to between 3815 and 855 950, depending on the soil property, and 366 environmental covariates. We assess the accuracy of mean and median predictions using design-based statistical inference of a probability sample and location-grouped 10-fold cross validation (CV) and prediction uncertainty using the prediction interval coverage probability. We found that the accuracy of clay, sand and pH maps was the highest, with the model efficiency coefficient (MEC) ranging between 0.6 and 0.92 depending on depth. Silt, bulk density, soil organic matter, total nitrogen and cation exchange capacity (MEC of 0.27 to 0.78), and especially oxalate-extractable phosphorus (MEC of −0.11 to 0.38) were more difficult to predict. One of the main limitations of BIS-4D is that prediction maps cannot be used to quantify the uncertainty in spatial aggregates. We provide an example of good practice to help users decide whether BIS-4D is suitable for their intended purpose. An overview of all maps and their uncertainties can be found in the Supplement. Openly available code and input data enhance reproducibility and help with future updates. BIS-4D prediction maps can be readily downloaded at https://doi.org/10.4121/0c934ac6-2e95-4422-8360-d3a802766c71 (Helfenstein et al., 2024a). BIS-4D fills the previous data gap of the national-scale GlobalSoilMap product in the Netherlands and will hopefully facilitate the inclusion of soil spatial variability as a routine and integral part of decision support systems.
A spatiotemporally separated framework for reconstructing the sources of atmospheric radionuclide releases
Authors: Xu Yuhan , Fang Sheng , Dong Xinwen , Zhuang Shuhan
Published: June 2024

Abstract. Determining the source location and release rate are critical tasks when assessing the environmental consequences of atmospheric radionuclide releases, but they remain challenging because of the huge multi-dimensional solution space. We propose a spatiotemporally separated two-step framework that reduces the dimension of the solution space in each step and improves the source reconstruction accuracy. The separation process applies a temporal sliding-window average filter to the observations, thereby reducing the influence of temporal variations in the release rate on the observations and ensuring that the features of the filtered data are dominated by the source location. A machine-learning model is trained to link these features to the source location, enabling independent source-location estimations. The release rate is then determined using the projected alternating minimization with L1 norm and total variation regularization algorithm. This method is validated against the local-scale SCK CEN (Belgian Nuclear Research Centre) 41Ar field experiment and the first release of the continental-scale European Tracer Experiment, for which the lowest source-location errors are 4.52 m and 5.19 km, respectively. This presents higher accuracy and a smaller uncertainty range than the correlation-based and Bayesian methods when estimating the source location. The temporal variations in release rates are accurately reconstructed, and the mean relative errors in the total release are 65.09 % and 72.14 % lower than the Bayesian method for the SCK CEN experiment and the European Tracer Experiment, respectively. A sensitivity study demonstrates the robustness of the proposed method to different hyperparameters. With an appropriate site layout, low error levels can be achieved from only a single observation site or under meteorological errors.
A comprehensive framework for stochastic calibration and sensitivity analysis of large-scale groundwater models
Authors: Manzoni Andrea , Porta Giovanni Michele , Guadagnini Laura , Guadagnini Alberto , Riva Monica
Published: June 2024

Abstract. We introduce a comprehensive and robust theoretical framework and operational workflow that can be employed to enhance our understanding, modeling and management capability of complex heterogeneous large-scale groundwater systems. Our framework encapsulates key components such as the three-dimensional nature of groundwater flows, river–aquifer interactions, probabilistic reconstruction of three-dimensional spatial distributions of geomaterials and associated properties across the subsurface, multi-objective optimization for model parameter estimation through stochastic calibration, and informed global sensitivity analysis (GSA). By integrating these components, we effectively consider the inherent uncertainty associated with subsurface system characterizations as well as their interactions with surface waterbodies. The approach enables us to identify parameters impacting diverse system responses. By employing a coevolutionary optimization algorithm, we ensure efficient model parameterization, facilitating simultaneous and informed optimization of the defined objective functions. Additionally, estimation of parameter uncertainty naturally leads to quantification of uncertainty in system responses. The methodology is designed to increase our knowledge of the dynamics of large-scale groundwater systems. It also has the potential to guide future data acquisition campaigns through an informed global sensitivity analysis. We demonstrate the effectiveness of our proposed methodology by applying it to the largest groundwater system in Italy. We address the challenges posed by the characterization of the heterogeneous spatial distribution of subsurface attributes across large-scale three-dimensional domains upon incorporating a recent probabilistic hydrogeological reconstruction specific to the study case. The system considered faces multiple challenges, including groundwater contamination, seawater intrusion, and water scarcity. Our study offers a promising modeling strategy applicable to large-scale subsurface systems and valuable insights into groundwater flow patterns that can then inform effective system management.
Multi-scale variations of subglacial hydro-mechanical conditions at Kongsvegen glacier, Svalbard

Published: June 2024

Abstract. The flow of glaciers is largely controlled by changes at the ice–bed interface, where basal slip and sediment deformation drive basal glacier motion. Determining subglacial conditions and their responses to hydraulic forcing remains challenging due to the difficulty of accessing the glacier bed. Here, we monitor the interplay between surface runoff and hydro-mechanical conditions at the base of the Kongsvegen glacier in Svalbard. From July 2021 to August 2022, we measured both subglacial water pressure and till strength. Additionally, we derived median values of subglacial hydraulic gradient and radius of channelized subglacial drainage system from seismic power, recorded at the glacier surface. To characterize the variations in the subglacial conditions caused by changes in surface runoff, we investigate the variations of the following hydro-mechanical properties: measured water pressure, measured sediment ploughing forces, and derived hydraulic gradient and radius, over seasonal, multi-day, and diurnal timescales. We discuss our results in light of existing theories of subglacial hydrology and till mechanics to describe subglacial conditions. We find that during the short, low-melt-rate season in 2021, the subglacial drainage system evolved at equilibrium with runoff, increasing its capacity as the melt season progressed. In contrast, during the long and high-melt-rate season in 2022, the subglacial drainage system evolved transiently to respond to the abrupt and large water supply. We suggest that in the latter configuration, the drainage capacity of the preferential drainage axis was exceeded, promoting the expansion of hydraulically connected regions and local weakening of ice–bed coupling and, hence, enhanced sliding.
Simulating low-frequency wind fluctuations
Authors: Syed Abdul Haseeb , Mann Jakob
Published: June 2024

Abstract. Large-scale flow structures are vital in influencing the dynamic response of floating wind turbines and wake meandering behind large offshore wind turbines. It is imperative that we develop an inflow wind turbulence model capable of replicating the large-scale and low-frequency wind fluctuations occurring in the marine atmosphere since the current turbulence models do not account well for this phenomenon. Here, we present a method to simulate low-frequency wind fluctuations. This method employs the two-dimensional (2D) spectral tensor for low-frequency, anisotropic wind fluctuations presented by Syed and Mann (2024) to generate stochastic wind fields. The simulation method generates large-scale 2D spatial wind fields for the longitudinal u and lateral v wind components, which can be converted into a frequency domain using Taylor's frozen turbulence hypothesis. The low-frequency wind turbulence is assumed to be independent of the high-frequency turbulence; thus, a broad spectral representation can be obtained just by superposing the two turbulent wind fields. The method is tested by comparing the simulated and theoretical spectra and co-coherences of the combined low- and high-frequency fluctuations. Furthermore, the low-frequency wind fluctuations can also be subjected to anisotropy. The resulting wind fields from this method can be used to analyze the impact of low-frequency wind fluctuations on wind turbine loads and dynamic response and to study the wake meandering behind large offshore wind farms.
El misterio de Medea: el sentido primigenio del personaje en la literatura y en el cine
Authors: Fernández Gómez Encarnación
Published: June 2024

Dentro del arte cinematográfico –a diferencia del literario– el personaje de Medea ha sido llevado a la pantalla desde la ausencia de significaciones condenatorias de carácter moral. La esencia primigenia del mito de Medea en el cine se presenta desvinculada del punto de vista filosófico, científico y racional, pues su sentido último escapa, incluso, al propio lenguaje literario. Ciertamente, los más sobresalientes creadores cinematográficos han dado vida a esta figura mitológica en relación con lo inefable, esto es, como arquetipo imaginario productor de sentido: unido a lo simbólico, al silencio, al misterio y al arte.

La metodología desarrollada ha consistido en el análisis y cotejo de un amplio conjunto de fuentes orales, archivísticas y hemerográficas; la revisión sistemática de fuentes bibliográficas, como anuarios y guías comerciales, tanto regionales como nacionales y el análisis crítico del corpus de obras fotográficas conservadas en instituciones y en colecciones privadas.
Retórica y periodismo como artesanías del espíritu ante el reto del algoritmo
Authors: Núñez Ladevéze Luis , Núñez Canal Margarita , Álvarez de Mon Ignacio
Published: June 2024

Este artículo analiza dos explicaciones de por qué la retórica ha sobrevivido más de dos milenios hasta la actualidad. La filosofía del lenguaje de Ortega y Gasset se centró en que el acontecer personal del hablante es irreductible a los automatismos sociales. Chomsky analizó los automatismos que actúan en la gramaticalización para concluir que la competencia es irreductible al algoritmo. Ambos remontan, a través de Humboldt, a la idea platónica del lenguaje. Según Chomsky la lengua aborda situaciones nuevas con recursos memorísticos incomparablemente inferiores a los de una máquina generadora de textos, como el ChatGPT. Siguiendo a Ortega cada persona produce innumerables decires nuevos en la diversidad de situaciones, razón por la que perdura la retórica. Ambos argumentos explican que, por potente que sea, la máquina no puede conseguir la plena simulación moral de la inconmensurable intencionalidad humana.
Propuesta de análisis de la calidad de la televisión pública: estudio de caso, TVE ante la llegada de las cadenas privadas (1990-2010)
Authors: Antona-Jimeno Tamara , Martín Quevedo Juan , Pascual-Gutiérrez Iris
Published: June 2024

Las dos décadas que mediaron entre la llegada de las televisiones privadas en 1990 y la consolidación del modelo para RTVE establecido en la Ley de la radio y la televisión estatal de 2006 fueron de una enorme dificultad para RTVE, pues tuvo que adaptarse a un ecosistema mediático totalmente diferente de forma improvisada y con recursos gravemente limitados. El ente intentó mantener la calidad de la programación como elemento de identidad frente a unas cadenas privadas volcadas en contenidos puramente comerciales para captar la audiencia que TVE perdía a borbotones. Esta investigación aborda cuáles fueron las claves de ese contenido de calidad. A través de una muestra de 91.610 emisiones se han organizado los contenidos en bloques, géneros y subgéneros, para comprobar la evolución de los minutos de emisión. También se ha estudiado la evolución de las audiencias y el discurso que la propia TVE tenía sobre sí misma.
“Contacta con expertos y pacientes”: evolución de las fuentes de las informaciones de salud tras la COVID19
Authors: Ugarte-Iturrizaga Aitor , Catalán-Matamoros Daniel
Published: June 2024

Las fuentes condicionan la calidad y orientación de las noticias de salud y permiten explicar y humanizar los datos. Con el objetivo de conocer si hubo cambios en las fuentes periodísticas sobre salud tras la pandemia, se analizaron los contenidos de prensa, radio y televisión generalistas de gran audiencia en España y se entrevistó a 16 periodistas especializados. Los resultados cuantitativos muestran que los expertos son la fuente principal más frecuente tras la COVID19, seguidos de los pacientes y las instituciones del Estado, lo que supone un cambio significativo (p < 0,001) respecto a prepandemia, cuando las instituciones ocupaban el primer lugar. Cualitativamente, los periodistas de salud manifiestan su crítica y desconfianza hacia las fuentes oficiales. Se concluye que existen cambios y una evolución en las fuentes periodísticas de salud en España, que posteriores estudios determinarán si solo afecta a medios generalistas.
Tilhøvet mellom fastsette og operative normer i bokmål
Authors: Helset Stig J.
Published: June 2024

Denne artikkelen undersøker korleis valfridomen innanfor offisielt bokmål nedfeller seg i operative normer i eit stort og breitt samansett utval av redigerte bokmålstekstar. Hausten 2021 vedtok styret i Språkrådet nye retningslinjer for normering av bokmål og nynorsk. I desse retningslinjene heiter det at «[d]et vesentlege grunnlaget for normeringa av bokmål er slik det ser ut i bokmålstekstar», og at normeringsgrunnlaget i første rekkje skal vere «tekstar som har vore gjennom ein redigeringsprosess». Med det til siktemål å styrke kunnskapsgrunnlaget for den vidare normeringa av bokmål har vi derfor gjennomført ein studie der vi har kartlagt bruken av ulike valfrie ordformer mellom 150 språklege variablar i eit breitt samansett utval av 452 redigerte og publiserte tekstar som ligg i Leksikografisk bokmålskorpus. I tillegg til registrering og komparasjon av bruksfrekvensar for ulike valfrie former innanfor einskildvariablar, har vi brukt statistisk korrespondanseanalyse for å kartlegge normklynger av ulike subvarietetar av bokmål. Hovud­konklusjonen er at dei moderate formene dominerer over dei radikale formene for dei aller fleste einskildvariablane som er med i studien, samstundes som dei radikale formene dominerer over dei moderate for nokre få av einskildvariablane, og at det mellom tekstane i utvalet som er med i studien, eksisterer ei operativ normklynge som ein kan karakterisere som moderat bokmål.

Ion Antonescu and the Church
Authors: Ţurcanu Mihai
Published: June 2024

This study refers to the attitude of Ion Antonescu towards the Romanian Orthodox Church. The documentary sources used for this study which, as far as I am aware, is the first of its kind, are drawn from the transcripts of the governmental meetings, held mostly during September 1940 – April 1941, i.e. from the moment Ion Antonescu took over the supreme leadership of the and until he decided to focus primarily on military preparations. This study shows that Ion Antonescu considered that the Orthodox Church should play the role of a kind of special ministry of the state, in charge of facilitating control over the population; in Antonescu`s vision, the state was to be the main beneficiary of such an arrangement, but it was willing to share those benefits with the church. For Ion Antonescu, this „philosophy” had two main theses–consequences. The first was that the Romanian state needed the Orthodox Church and, therefore, had to support its existence by both political and material means, and the second was that the priesthood, in its activity, had to meet minimum „ethical–moral standards” that would allow it to fulfill its role as an instrument of ideological control over the population.
Stylistic and structural peculiarities of the sonata ”Ludus Fistula” for flute and piano by Pavel Rusu
Authors: Serbinov Maria
Published: June 2024

Pavel Rusu’s creation encompasses a wide range of musical genres, ranging from symphonic and choral to chamber music – both instrumental and vocal. Stylistically, P. Rusu was attracted by the diversity of 20th-century composition on the one hand, and on the other, he was particularly interested in folklore, allowing this field to shape his individual compositional style, while his opuses were dominated by the intonation and colors of folk music. The Sonata for Flute and Piano Ludus Fistula (1984) is a concert piece that perfectly exemplifies these observations. Having never been researched or published, the Sonata will be the object of study of the present article, in which the first attempts are made to fill this gap in the historiography of national music..
