Abstract. Demand for coconut is expected to rise, but the global
distribution of coconut palm has been studied little, which hinders the discussion
of its impacts. Here, we produced the first 20 m global coconut palm
layer using a U-Net model that was trained on annual Sentinel-1 and
Sentinel-2 composites for the year 2020. The overall accuracy was 99.04 ± 0.21 %, which was significantly higher than the no-information
rate. The producer's accuracy for coconut palm was 71.51 ± 23.11 %
when only closed-canopy coconut palm was considered in the validation, but this
decreased to 11.30 ± 2.33 % when sparse and dense open-canopy
coconut palm was also taken into account. This indicates that sparse and
dense open-canopy coconut palm remains difficult to map with accuracy. We
report a global coconut palm area of 12.66 ± 3.96 × 106 ha for
dense open- and closed-canopy coconut palm, but the estimate is 3 times
larger (38.93 ± 7.89 × 106 ha) when sparse coconut palm is
included in the area estimation. The large area of sparse coconut palm is
important as it indicates that production increases can likely be achieved
on the existing lands allocated to coconut. The Philippines, Indonesia, and
India account for most of the global coconut palm area, representing
approximately 82 % of the total mapped area. Our study provides the
high-resolution, quantitative, and precise data necessary for assessing the
relationships between coconut production and the synergies and trade-offs
between various sustainable development goal indicators. The global coconut
palm layer is available at https://doi.org/10.5281/zenodo.8128183 (Descals, 2023).
Spatially coherent variability in modern orographic precipitation produces asymmetric paleo-glacier extents in flowline models: Olympic Mountains, USA
Authors: Margason Andrew A. , Anders Alison M. , Conrick Robert J. C. , Roe Gerard H.
Published: September 2023

Abstract. Glaciers are sensitive to temporal climate variability. Glacier sensitivity to spatial variability in climate has been much less studied. The Olympic Mountains of Washington state, USA, experience a pronounced orographic precipitation gradient, with modern annual precipitation ranging between ∼6500 and ∼500 mm water equivalent. In the Quinault valley, on the wet side of the range, a glacier extended onto the coastal plain, reaching a maximum position during the Early Wisconsin glaciation. On the dry side of the range, in the Elwha valley, there is no evidence of a large paleo-glacier during the Wisconsin glaciation. We hypothesize that asymmetry in the past glacier extent was driven by spatial variability in precipitation. To evaluate this hypothesis, we constrain the past precipitation gradient and model the glacier extent. We explore variability in observed and modeled precipitation gradients over timescales from 6 h to ∼100 yr. Across three datasets, basin-averaged precipitation in the Elwha is 54 % of that in the Quinault. Our analysis overwhelmingly indicates spatially coherent variability in precipitation across the peninsula. We conclude that the past precipitation gradient was likely similar to the modern gradient. We use a one-dimensional glacier flowline model, driven by sea level summer temperature and annual precipitation to approximate the glacier extent in the Quinault and Elwha valleys. We find several equilibrium states for the Quinault glacier at the mapped maximum position within paleoclimate constraints for cooling and drying, relative to present-day conditions. Assuming stable precipitation gradients, we model the Elwha glacier extent for the climates of these equilibria. At the warm end of the paleoclimate constraint (July average sea level temperature of 10.5 ∘C), a small valley glacier occurs in the high headwaters of the Elwha valley. Yet, for the cooler end of the allowable paleoclimate (July average sea level temperature of 7 ∘C), the Elwha glacier advances to a narrow notch in the valley, thickens, and rapidly extends far beyond the likely true maximum extent. Therefore, we suggest that the Early Wisconsin period was more likely to have been relatively warm because our models of the glacial extent are consistent with the past record of glaciation in both the Quinault valley and Elwha valley for warm conditions but inconsistent for cooler conditions. Alternatively, spatially variable drivers of ablation, including differences in cloudiness, could have contributed to past asymmetry in the glacier extent. Future research
to constrain past precipitation gradients and evaluate their impact on
glacier dynamics is needed to better interpret the climatic significance of past glaciation and to predict the future response of glaciers to climate
change.
Simulated stable water isotopes during the mid-Holocene and pre-industrial periods using AWI-ESM-2.1-wiso

Published: September 2023

Abstract. Numerical simulations employing prognostic stable water isotopes can not only facilitate our understanding of hydrological processes and climate change but also allow for a direct comparison between isotope signals obtained from models and various archives. In the current work, we describe the performance and explore the potential of a new version of the Earth system model AWI-ESM (Alfred Wegener Institute Earth System Model), labeled AWI-ESM-2.1-wiso, in which we incorporated three isotope tracers into all relevant components of the water cycle. We present here the results of pre-industrial (PI) and mid-Holocene (MH) simulations. The model reproduces the observed PI isotope compositions in both precipitation and seawater well and captures their major differences from the MH conditions. The simulated relationship between the isotope composition in precipitation (δ18Op) and surface air temperature is very similar between the PI and MH conditions, and it is largely consistent with modern observations despite some regional model biases. The ratio of the MH–PI difference in δ18Op to the MH–PI difference in surface air temperature is comparable to proxy records over Greenland and Antarctica only when summertime air temperature is considered. An amount effect is evident over the North African monsoon domain, where a negative correlation between δ18Op and the amount of precipitation is simulated. As an example of model applications, we studied the onset and withdrawal date of the MH West African summer monsoon (WASM) using daily variables. We find that defining the WASM onset based on precipitation alone may yield erroneous results due to the substantial daily variations in precipitation, which may obscure the distinction between pre-monsoon and monsoon seasons. Combining precipitation and isotope indicators, we suggest in this work a novel method for identifying the commencement of the WASM. Moreover, we do not find an obvious difference between the MH and PI periods in terms of the mean onset of the WASM. However, an advancement in the WASM withdrawal is found in the MH compared to the PI period due to an earlier decline in insolation over the northern location of Intertropical Convergence Zone (ITCZ).
Open-ocean tides simulated by ICON-O, version icon-2.6.6

Published: September 2023

Abstract. This paper evaluates barotropic tides simulated by a newly developed multi-layer ocean general circulation, ICON-O, and assesses processes and model configurations that can impact the quality of the simulated tides. Such an investigation is crucial for applications addressing internal tides that are much more difficult to evaluate than the barotropic tides.
Although not specially tuned for tides and not constrained by any observations, ICON-O is capable of producing the main features of the open-ocean barotropic tides as described by the geographical distributions of amplitude, phase, and amphidromic points. An error analysis shows, however, that the open-ocean tides simulated by ICON-O are less accurate than those simulated by two other ocean general circulation models (OGCMs), especially when not properly adjusting the time step and the parameters used in the time-stepping scheme. Based on a suite of tidal experiments, we show that an
increase in horizontal resolution only improves tides in shallow waters. Relevant for using ICON-O with its telescoping grid capacity, we show that spatial inhomogeneity does not deteriorate the quality of the simulated tides. We further show that implementing a parameterization of topographic wave drag improves the quality of the simulated tides in deep ocean independent of the model configuration used, whereas the implementation of a self-attraction and loading (SAL) parameterization in a low-resolution (40 km) version of ICON-O degrades the quality of tides in shallow ocean.
Finally, we show that the quality of tides simulated by ICON-O with low resolution (40 km) can be significantly improved by adjusting the time step or the parameters in the time-stepping scheme used for obtaining the model solution.
Improved representation of volcanic sulfur dioxide depletion in Lagrangian transport simulations: a case study with MPTRAC v2.4
Authors: Liu Mingzhao , Hoffmann Lars , Griessbach Sabine , Cai Zhongyin , Heng Yi , Wu Xue
Published: September 2023

Abstract. The lifetime of sulfur dioxide (SO2) in the Earth's atmosphere varies from orders of hours to weeks, mainly depending on whether cloud water is present or not. The volcanic eruption on Ambae Island, Vanuatu, in July 2018 injected a large amount of SO2 into the upper troposphere and lower stratosphere (UT/LS) region with abundant cloud cover. In-cloud removal is therefore expected to play an important role during long-range transport and dispersion of SO2. In order to better represent the rapid decay processes of SO2 observed by the Atmospheric Infrared Sounder (AIRS) and the TROPOspheric Monitoring Instrument (TROPOMI) in Lagrangian transport simulations, we simulate the SO2 decay in a more realistic manner compared to our earlier work, considering gas-phase hydroxyl (OH) chemistry, aqueous-phase hydrogen peroxide (H2O2) chemistry, wet deposition, and convection. The either newly developed or improved chemical and physical modules are implemented in the Lagrangian transport model Massive-Parallel Trajectory Calculations (MPTRAC) and tested in a case study for the July 2018 Ambae eruption. To access the dependencies of the SO2 lifetime on the complex atmospheric conditions, sensitivity tests are conducted by tuning the control parameters, e.g., by changing the release height, the predefined OH climatology data, the cloud pH value, the cloud cover, and other variables. Wet deposition and aqueous-phase H2O2 oxidation remarkably increased the decay rate of the SO2 total mass, which leads to a rapid and more realistic depletion of the Ambae plume. The improved representation of chemical and physical SO2 loss processes described here is expected to lead to more realistic Lagrangian transport simulations of volcanic eruption events with MPTRAC in future work.
Metrics for evaluating the quality in linear atmospheric inverse problems: a case study of a trace gas inversion
Authors: Yadav Vineet , Ghosh Subhomoy , Miller Charles E.
Published: September 2023

Abstract. Several metrics have been proposed and utilized to diagnose the performance of linear Bayesian and geostatistical atmospheric inverse problems. These metrics primarily assess the reductions in the prior uncertainties, compare modeled observations to true observations, and check distributional assumptions. Although important, these metrics should be augmented with a sensitivity analysis to obtain a comprehensive understanding of the atmospheric inversion performance and improve the quality and confidence in the inverse estimates. In this study, we derive closed-form expressions of local sensitivities for various input parameters, including measurements, covariance parameters, covariates, and a forward operator. To further enhance our understanding, we complement the local sensitivity analysis with a framework for a global sensitivity analysis that can apportion the uncertainty in input parameters to the uncertainty associated with inverse estimates. Additionally, we propose a mathematical framework to construct nonstationary correlation matrices from a precomputed forward operator, which is closely tied to the overall quality of inverse estimates. We demonstrate the application of our methodology in the context of an atmospheric inverse problem for estimating methane fluxes in Los Angeles, California.

Abstract. Anthropogenic climate change is changing the earth system processes that control the characteristics of natural hazards both globally and across Australia. Model projections of hazards under future climate change are necessary for effective adaptation. This paper presents BARPA-R (the Bureau of Meteorology Atmospheric Regional Projections for Australia), a regional climate model designed to downscale climate projections over the Australasian region with the purpose to investigate future hazards. BARPA-R, a limited area model, has a 17 km horizontal grid-spacing and makes use of the Met Office Unified Model (MetUM) atmospheric model and the Joint UK Land Environment Simulator (JULES) land surface model. To establish credibility and in compliance with the Coordinated Regional Climate Downscaling Experiment (CORDEX) experiment design, the BARPA-R framework has been used to downscale ERA-5 reanalysis. Here, an assessment of this evaluation experiment is provided. First, an examination of BARPA-R’s representation of Australia’s surface air temperature, rainfall and 10-m winds finds good performance overall, with biases including a 1 K cold bias in daily maximum temperatures, reduced diurnal temperature range, and wet biases up to 25 mm/month in inland Australia. Recent trends in diurnal maximum temperatures are consistent with observational products, while trends in minimum temperatures show overestimated warming and trends in rainfall show underestimated wetting in northern Australia. Rainfall and temperature teleconnections are effectively represented in BARPA-R when present in the driving boundary conditions, while 10-metre winds are improved over ERA5 in six out of eight of the Australian regions considered. The second section of the paper considers the representation of large-scale atmospheric circulation features and weather systems. While generally well represented, convection-related features such as tropical cyclones, the SPCZ, Northwest Cloud-Bands and the monsoon westerlies show more divergence from observations and internal interannual variability than mid-latitude phenomena such as the westerly jets and extra-tropical cyclones. Having simulated a realistic Australasian climate, the BARPA-R framework will be used to downscale two climate change scenarios from seven CMIP6 GCMs.
What is the Priestley–Taylor wet-surface evaporation parameter? Testing four hypotheses
Authors: Crago Richard D. , Szilagyi Jozsef , Qualls Russell J.
Published: September 2023

Abstract. This study compares four different hypotheses regarding the nature
of the Priestley–Taylor parameter α. They are as follows:
α is a universal constant. The Bowen ratio (H/LE, where H is the sensible heat flux, and LE is
the latent heat flux) for equilibrium (i.e., saturated air column near the
surface) evaporation is a constant times the Bowen ratio at minimal
advection (Andreas et al., 2013). Minimal advection over a wet surface corresponds to a particular relative humidity value. α is a constant fraction of the difference from the minimum value of 1 to the maximum value of α proposed by Priestley and Taylor (1972).
Formulas for α are developed for the last three hypotheses. Weather,
radiation, and surface energy flux data from 171 FLUXNET eddy covariance
stations were used. The condition LEref/LEp> 0.90 was
taken as the criterion for nearly saturated conditions (where LEref is
the reference, and LEp is the apparent potential evaporation rate from the equation by Penman, 1948). Daily and monthly average data from the sites were
obtained. All formulations for α include one model parameter which
is optimized such that the root mean square error of the target variable was
minimized. For each model, separate optimizations were done for predictions
of the target variables α, wet-surface evaporation (α
multiplied by equilibrium evaporation rate) and actual evaporation (the
latter using a highly successful version of the complementary relationship
of evaporation). Overall, the second and fourth hypotheses received the best
support from the data.
Calibration of groundwater seepage against the spatial distribution of the stream network to assess catchment-scale hydraulic properties

Published: September 2023

Abstract. The assessment of effective hydraulic properties at the catchment scale,
i.e., hydraulic conductivity (K) and transmissivity (T), is particularly
challenging due to the sparse availability of hydrological monitoring
systems through stream gauges and boreholes. To overcome this challenge, we
propose a calibration methodology which only considers information from a digital elevation model (DEM) and the spatial distribution of the stream
network. The methodology is built on the assumption that the groundwater
system is the main driver controlling the stream density and extension,
where the perennial stream network reflects the intersection of the
groundwater table with the topography. Indeed, the groundwater seepage at
the surface is primarily controlled by the topography, the aquifer
thickness and the dimensionless parameter K/R, where R is the average
recharge rate. Here, we use a process-based and parsimonious 3D groundwater
flow model to calibrate K/R by minimizing the relative distances between
the observed and the simulated stream network generated from groundwater
seepage zones. By deploying the methodology in 24 selected headwater
catchments located in northwestern France, we demonstrate that the method
successfully predicts the stream network extent for 80 % of the cases.
Results show a high sensitivity of K/R to the extension of the low-order
streams and limited impacts of the DEM resolution as long the DEM remains
consistent with the stream network observations. By assuming an average
recharge rate, we found that effective K values vary between 1.0×10-5 and 1.1×10-4 m s−1, in agreement with local estimates derived from hydraulic tests and independent calibrated groundwater model. With the emergence of global remote-sensing databases compiling information on high-resolution DEM and stream networks, this approach provides new opportunities to assess hydraulic properties of unconfined aquifers in ungauged basins.
Towards reducing the high cost of parameter sensitivity analysis in hydrologic modeling: a regional parameter sensitivity analysis approach

Published: September 2023

Abstract. Land surface models have many parameters that have a spatially variable impact on model outputs. In applying these models, sensitivity analysis (SA) is sometimes performed as an initial step to select calibration parameters. As these models are applied to large domains, performing sensitivity analysis across the domain is computationally prohibitive. Here, using a Variable Infiltration Capacity model (VIC) deployment to a large domain as an example, we show that watershed classification based on climatic attributes and vegetation land cover helps to identify the spatial pattern of parameter sensitivity within the domain at a reduced cost. We evaluate the sensitivity of 44 VIC model parameters with regard to streamflow, evapotranspiration and snow water equivalent over 25 basins with a median size of 5078 km2. Basins are clustered based on their climatic and land cover attributes. Performance in transferring parameter sensitivity between basins of the same cluster is evaluated by the F1 score. Results show that two donor basins per cluster are sufficient to correctly identify sensitive parameters in a target basin, with F1 scores ranging between 0.66 (evapotranspiration) and 1 (snow water equivalent). While climatic attributes are sufficient to identify sensitive parameters for streamflow and evapotranspiration, including the vegetation class significantly improves skill in identifying sensitive parameters for the snow water equivalent. This work reveals that there is opportunity to leverage climate and land cover attributes to greatly increase the efficiency of parameter sensitivity analysis and facilitate more rapid deployment of land surface models over large spatial domains.

Abstract. The Tibetan Plateau and its surroundings have recently experienced several catastrophic glacier-related disasters. It is of great scientific and practical significance to establish ground-based early warning systems (EWSs) to understand the processes and mechanisms of glacial disasters and warn against potential threats to downstream settlements and infrastructure. However, there are few sophisticated EWSs on the Tibetan Plateau. With the support of the Second Tibetan Plateau Scientific Expedition and Research Program (STPSER), an EWS was developed and
implemented in the Sedongpu Valley, southeastern Tibetan Plateau, where
repeated river blockages have occurred due to ice/rock collapse debris flow.
The EWS collected datasets of optical/thermal videos/photos, geophone
waveforms, water levels, and meteorological variables in this sparsely
populated zone. It has successfully warned against three ice-rock collapse–debris flow–river blockage chain events, and seven small-scale ice-rock collapse–debris flow events. Meanwhile, it was found that the low-cost geophone can effectively indicate the occurrence and magnitude of ice/rock collapses by local thresholds, and water level observation is an efficient way to warn of river blockages. Our observations showed that there were no immediate meteorological triggers for the ice-rock collapses and associated debris flows. Several factors, such as the volume and location of the collapses and the percentage of ice content involved, influence the velocities of debris flows and the magnitude of river blockages. There are still two possible glaciers in the study area that are at risk of ice collapse. It is worth monitoring their dynamic changes using high-resolution satellite data and the ground-based EWS to safeguard the surrounding hydrological projects and infrastructure in this transboundary region.
Rapid estimation of seismic intensities by analyzing early aftershock sequences using the robust locally weighted regression program (LOWESS)
Authors: Zhao Huaiqun , Chen Wenkai , Zhang Can , Kang Dengjie
Published: September 2023

Abstract. Accurate and rapid assessment of seismic intensity after a destructive earthquake is essential for efficient early emergency response. We proposed
an improved method, AL-SM99, to assess seismic intensity by analyzing aftershock sequences that occur within 2 h of mainshocks. The
implementation effect and application conditions of this method were illustrated using 27 earthquakes with Mw 6.5–8.3 that occurred
globally between 2000 and 2023. When the fault system in the seismic region is clear and simple, the robust LOWESS-fitted (locally weighted regression program) curves could be used to estimate the location and length of the fault rupture. LOWESS results can indicate the overall rupture trend
and make reliable rupture-scale judgments even when the fault system is complex. When Mw ≥ 7.0 and the number of aftershocks
exceeds 40, the AL-SM99 intensity evaluation results may be more reliable. Using aftershock catalogues obtained by conventional means allows for a
stable assessment of seismic intensities within 1.5 h of the mainshock. When the number of aftershocks is sufficiently large, the intensity assessment time can be greatly reduced. With early accessible aftershocks, we can quickly determine the rupture fault planes and have a better estimate of the seismic intensities. The results of the intensity assessment provide a useful guide for determining the extent of the hardest-hit areas. By expanding the data sources for seismic intensity assessment, the early accessible data are utilized adequately. This study provides a valuable reference point for investigating the relationship between early aftershock events and fault rupture.

Abstract. Here, we present a compilation of 95 ice temperature profiles from 85 boreholes from the Greenland ice sheet and peripheral ice caps, as well as local ice caps in the Canadian Arctic. Profiles from only 31 boreholes (36 %) were previously available in open-access data repositories. The remaining 54 borehole profiles (64 %) are being made digitally available here for the first time. These newly available profiles, which are associated with pre-2010 boreholes, have been submitted by community members or digitized from published graphics and/or data tables. All 95 profiles are now made available in both absolute (meters) and normalized (0 to 1 ice thickness) depth scales and are accompanied by extensive metadata. These metadata include a transparent description of data provenance. The ice temperature profiles span 70 years, with the earliest profile being from 1950 at Camp VI, West Greenland. To highlight the value of this database in evaluating ice flow simulations, we compare the ice temperature profiles from the Greenland ice sheet with an ice flow simulation by the Parallel Ice Sheet Model (PISM). We find a cold bias in modeled near-surface ice temperatures within the ablation area, a warm bias in modeled basal ice temperatures at inland cold-bedded sites, and an apparent underestimation of deformational heating in high-strain settings. These biases provide process level insight on simulated ice temperatures.

Published: September 2023

This research investigated the heat transfer in safe rooms exposed to bushfires and their bushfire resistance using full-scale laboratory and out-door experimental studies of external wall systems and a safe room, and associated advanced numerical studies. It has advanced the knowledge and understanding of the heat transfer and the performance of the critical external building envelope and the safe rooms with different configurations exposed to bushfire flame conditions. Suitable solutions and methodologies have been proposed, addressing various complexities and challenges, which can be used in any bushfire-prone country like Australia. This will improve life safety and community resilience during bushfires.
From Entry to Finals: Progression and Variability of Swimming Performance at the 2022 FINA World Championships
Authors: Santos Catarina C. , Fernandes Ricardo J. , Marinho Daniel A. , Costa Mário J.
Published: September 2023

The aim of the present study was two-fold: (i) to analyze the progression and variability of swimming performance (from entry times to best performances) in the 50, 100, and 200 m at the most recent FINA World Championships and (ii) to compare the performance of the Top16, semifinalists, and finalists between all rounds. Swimmers who qualified with the FINA A and B standards for the Budapest 2022 World Championships were considered. A total of 1102 individual performances swimmers were analyzed in freestyle, backstroke, breaststroke, and butterfly events. The data was retrieved from the official open-access websites of OMEGA and FINA. Wilcoxon test was used to compare swimmers’ entry times and best performances. Repeated measures ANOVA followed by the Bonferroni post-hoc test were performed to analyze the round-to-round progression. The percentage of improvement and variation in the swimmers’ performance was computed between rounds. A negative progression (entry times better than best performance) and a high variability (> 0.69%) were found for most events. The finalists showed a positive progression with a greater improvement (~1%) from the heats to the semifinals. However, the performance progression remained unchanged between the semifinals and finals. The variability tended to decrease between rounds making each round more homogeneous. Coaches and swimmers can use these indicators to prepare a race strategy between rounds.

Nuestra propuesta tiene el objetivo de analizar, mediante herramientas digitales cuantitativas y cualitativas, los mensajes que trataron la llegada de turistas extranjeros, y las palabras que se emplearon en los tuits al respecto, en la primavera del 2021, coincidente con las elecciones a la Comunidad de Madrid, cuya presidenta Díaz Ayuso revalidó su presidencia. Es por tanto un análisis que posee interés periodístico, político, y que nos permite conocer el estado institucional del país. Nos centramos en las palabras clave, es decir, significativamente más frecuentes en el corpus de estudio que en el corpus de comparación, así como en las combinaciones de palabras significativamente frecuentes, mediante la aplicación Sketch Engine, que calcula una puntuación para cada elemento. Aportamos claves para entender cómo de profundo es el mecanismo de generación de opinión pública en las redes, en un momento en que ya esto ya no es monopolio del periodismo.
De qué hablamos cuando hablamos de “propósito”: expresión y análisis discursivo del propósito corporativo en España
Authors: Sanahuja Peris Guillermo , Antón Carrillo Elvira , Mut Camacho Magdalena
Published: September 2023

El propósito corporativo ha emergido en los últimos años como un concepto de referencia en la gestión empresarial a partir de la progresiva exigencia de la ciudadanía sobre el impacto social y medioambiental de las compañías. Esta investigación se propone conocer de manera exploratoria el nivel de expresión de este “propósito” determinando el relato que transmiten y su contexto. El diseño metodológico consiste en una triangulación que combina el análisis de contenido en las webs de las 100 empresas más reputadas en España, el análisis del discurso que narran los “propósitos” y las entrevistas en profundidad a profesionales de la comunicación, de la publicidad y la gestión de intangibles que contrastan los hallazgos de las anteriores etapas. Los resultados muestran una desigual implantación, una confusión terminológica y la fijación de un gran eje discursivo - la sostenibilidad- que se plasma en tres áreas temáticas: progreso, mundo saludable o mejor vida.
¿De redes sociales a redes del odio? Análisis de la conversación digital en Twitter sobre la ministra de Igualdad española Irene Montero
Authors: Sánchez-Meza Metzeri , Schlesier Corrales Lluïsa , Visa Barbosa Mariona , Carnicé-Mur Marga
Published: September 2023

Con la llegada de Irene Montero al Ministerio de Igualdad (2020), se generó un clima de controversia en torno a sus políticas, traducible a un aumento de críticas hacia su persona en la red social Twitter. En 2022, la publicación del vídeo para la campaña contra la violencia de género #EntoncesQuién propició un incremento de violencia mediática, así como una normalización de discursos de odio machistas contra la ministra y el Ministerio. La presente investigación tiene como objetivo analizar y monitorear los discursos de odio en Twitter contra la ministra de igualdad Irene Montero publicados entre el 21 y el 25 de noviembre de 2022. Durante esta franja temporal ocurrieron dos sucesos significativos: a) la publicación del vídeo de la campaña #EntoncesQuien; b) las declaraciones difamatorias hacia la ministra de igualdad emitidas por el diputado del Partido Popular (PP) Víctor Píriz y la diputada de Vox, Carla Toscano. La muestra seleccionada fue analizada a través de análisis de contenido de tuits en español recogidos con la API de Twitter. El análisis de carácter cuantitativo se realizó de manera automatizada, se analizaron el Sentiment Analysis (SA) de 51.897 interacciones. En su vertiente cualitativa, se analizaron las 500 publicaciones más virales sobre la Ministra Irene Montero extraídas con el sistema de extracción muestral Top Discussion Indicator (TDI). Los resultados permiten afirmar que los discursos de odio (51,6%) y los mensajes de apoyo (48,4%) se viralizan en proporciones similares. Los discursos de odio más frecuentes corresponden a las subcategorías de descrédito (32,4%) y cuestionamiento político-económico (10,4%).

Amaç: Bu çalışmada bireylerin beslenme okuryazarlığı düzeyinin ev dışında beslenme, eve dışarıdan yemek sipariş etme ve sağlıklı besin tercihleri üzerinde etkisinin değerlendirilmesi amaçlanmıştır.

Gereç ve Yöntem: Araştırma 18-65 yaş arasında 393 gönüllü birey ile yürütülmüştür. Çevrimiçi anket yöntemi kullanılarak katılımcıların beslenme okuryazarlığı düzeyi, ev dışı yemek yeme, eve yemek sipariş etme sıklığı ve tercihleri sorgulanmıştır. Beslenme okuryazarlığını değerlendirmek için ‘Kendini Algılayan Gıda Okuryazarlığı Ölçeği’ (SPFLS) kullanılmıştır.

Bulgular: Araştırmaya 288 kadın (%73.3) ve 105 erkek (%26.7) katılmıştır. SPFLS toplam puan ortalaması kadın katılımcıların 89.58±12.21 iken, erkek katılımcıların 87.12±15.08 olarak bulunmuştur. Ev dışı yemek sipariş verme sıklığına göre toplam SPFLS puanı karşılaştırıldığında sık yemek sipariş edenler ile hiç/nadir ve seyrek sipariş veren grubun toplam SPFL puanları arasında istatistiksel olarak anlamlı fark bulunmuştur (p0.001). SPFLS toplam puanı medyan değerin (90) üzerinde olan katılımcıların sağlıklı yiyecek tüketim sıklığı (sebze, meyve, tam tahıl ürünler ve kurubaklagiller), medyan değerin altında olan katılımcılara göre yüksek bulunurken (sırasıyla p0.001, p=0.002, p0.001), sağlıksız tercihlerin (gazlı içecekler, hazır meyve suyu ve meşrubat) tüketim sıklığı, iş/okul haricinde ev dışında yeme sıklığı ve eve yemek sipariş etme sıklığı düşük bulunmuştur (sırasıyla p=0.012, p=0.001, p=0.002 ve p=0.004).

Sonuç: Beslenme okuryazarlık düzeyi arttıkça sağlıklı tercihler yapma yönünde eğilimin arttığı görülmüştür. Halk sağlığı üzerinde değiştirilebilir bir risk faktörü olan beslenme okuryazarlığı düzeyinin yükseltilmesi ile toplum sağlığının iyileştirilebileceği ön görülmektedir.
Personlige fortællinger som rådgivningsværktøj
Authors: Hedegaard Sine , Iversen Stefan , Wester Feodora
Published: September 2023

Det er velkendt i retorisk teori og i retorisk praksis, at talerådgivningens indledende sonderinger, typisk betegnet inventiofasen, har afgørende betydning for, hvor godt en taleskrivningsproces lykkes. Det overordnede argument i denne artikel er, at personlige fortællinger kan udgøre et privilegeret værktøj i sådanne inventiofaser. Argumentet hviler på et auktionsforskningsprojekt, gennemført som rådgivningsforløb i forbindelse med Kvindernes Internationale Kampdag i 2021. De tre klienter var ligestillingsordfører for Det Radikale Venstre, Samira Nawa, ligestillingsordfører for Venstre, Fatma Øktem og næstformand i Ligestillingsudvalget, Birgitte Vind. Artiklens bidrag er tosidet: I forhold til eksisterende håndbøger i retorisk rådgivningspraksis tilbyder den et specifikt, velbegrundet redskab, som har potentiale til at forbedre taleskrivningsprocesser, men som også medfører bestemte udfordringer. I forhold til eksisterende viden om fortællingers rolle i retorisk diskurs forskyder artiklen traditionens fokus. I stedet for at undersøge fortællinger som noget, der fra en færdig tale påvirker et publikum, undersøger artiklen fortællinger som noget, der udspiller sig i og kvalificerer relationen mellem en taleskriver og en rhetor, altså som en del af den proces, der går forud for en færdig tale.
Royal Responses to the Covid-19 Pandemic
Authors: Elmelund Kjeldsen Jens , De Jong Jaap , Atkins Judi
Published: September 2023

This article offers a rhetorical analysis of the addresses delivered by six Northern European monarchs in response to the Covid-19 pandemic in early 2020. The analysis establishes a new genre with distinctive traits and functions: They royal crisis address. This genre has two constitutive traits: To demonstrate the seriousness of the situation and to constitute the citizens and encourage them to behave in the right way. The genre also has three optional traits: to provide thanks, to empathise with those affected, and to reassure and inspire the nation. In a national crisis such as the Covid-19 pandemic, these rhetorical functions will also be performed by national leaders, however, because of the apolitical position and charismatic and historical power of the royals in the North European monarchies the royals can perform these functions with a special authority. We describe how this is done through the five functions and through epideictic and constitutive rhetoric.

The collection of metadata for research data is an important aspect in the FAIR principles. The schema.org and Bioschemas initiatives created a vocabulary to embed markup for many different types, including BioChemEntity, ChemicalSubstance, Gene, MolecularEntity, Protein, and others relevant in the Natural and Life Sciences with immediate benefits for findability of data packages. To bridge the gap between the worlds of semantic-web-driven JSON+LD metadata on the one hand, and established but separately developed interface services in libraries, we have designed an architecture for harmonising, federating and harvesting metadata from several resources. Our approach is to serve JSON+LD embedded in an XML container through a central OAI-Provider. Several resources in NFDI4Chem provide such domain-specific metadata. The CKAN-based NFDI4Chem search service can harvest this metadata using an OAI-PMH harvester extension that can extract the XML-encapsulated JSON+LD metadata, and has search capabilities relevant in the chemistry domain. We invite the community to collaborate and reach a critical mass of providers and consumers in the NFDI.

The Chemistry consortium NFDI4Chem aims to digitalise key steps in chemical research, supporting scientists in managing research data throughout its life cycle. The SmartLab, embedded in a federation of services, integrates various tools such as electronic lab notebooks, data repositories, and search services, to create a smart lab environment for structured data gathering. Utilizing terminology services and adhering to data format standards, NFDI4Chem promotes secure and FAIR data sharing, fostering collaboration and expediting scientific discoveries. This development is supported by community building measures, workshops, and training initiatives, along with collaboration on international minimum information standards.
BAM Data Store

Published: September 2023

As a partner in several NFDI consortia, the Bundesanstalt für Materialforschung und -prüfung (BAM, German federal institute for materials science and testing) contributes to research data standardization efforts in various domains of materials science and engineering (MSE). To implement a central research data management (RDM) infrastructure that meets the requirements of MSE groups at BAM, we initiated the Data Store pilot project in 2021. The resulting infrastructure should enable researchers to digitally document research processes and store related data in a standardized and interoperable manner. As a software solution, we chose openBIS, an open-source framework that is increasingly being used for RDM in MSE communities.
The pilot project was conducted for one year with five research groups across different organizational units and MSE disciplines. The main results are presented for the use case “nanoPlattform”. The group registered experimental steps and linked associated instruments and chemicals in the Data Store to ensure full traceability of data related to the synthesis of ~400 nanomaterials. The system also supported researchers in implementing RDM practices in their workflows, e.g., by automating data import and documentation and by integrating infrastructure for data analysis.
Based on the promising results of the pilot phase, we will roll out the Data Store as the central RDM infrastructure of BAM starting in 2023. We further aim to develop openBIS plugins, metadata standards, and RDM workflows to contribute to the openBIS community and to foster RDM in MSE.

Published: September 2023

Effective data management extends over the entire life cycle of data, from the point of creation through to dissemination and archiving, and usually continues long after a research project is concluded. Tailored guidance for management of research data is increasing its importance among data-driven scientific investigations. There is now increasing demand for Research Data Management (RDM), by funders and host institutions, for researchers to develop and implement data management plans for projects. The RDMkit, by ELIXIR Europe, is an open community-led resource designed to share knowledge on how to carry out RDM in life sciences research. It fills the training and learning gap by providing knowledge on domain-focused RDM considerations, task-focused solutions and resources, and tool assemblies that showcase real-life examples addressing how combinations of tools can be used to go through the data life cycle. The technical infrastructure of the RDMkit is reproducible, making it possible for other organisations to use the structure as a guide and inspiration to set up RDM source for their users. In this talk, RDMkit will be introduced with example best practice guidelines, and integrations and knowledge sources.

The PUNCH4NFDI consortium brings together scientists from the German particle physics, hadron and nuclear physics, astronomy, and astro-particle physics communities to improve the management and (re-)use of scientific data from these interrelated communities. The PUNCH sciences have a long tradition of building large instruments that are planned, constructed and operated by international collaborations. While the large collaborations typically employ advanced tools for data management and distribution, smaller-scale experiments often suffer from very limited resources to address these aspects. One of the aims of the consortium is to evaluate and enable or adopt existing solutions. Instances of a prototype federated and distributed computing and storage infrastructure have been set up at a handful of sites in Germany. This prototype is used to gain experience in running of scientific workflows to further guide the development of the Science Data Platform, which is an overarching goal of the consortium.
