Death marks in the city – contesting the signature of gendered necropolitics in Vitória, Brazil

I. M. M. Robaina, I. M. M. Robaina, P. B. Teixeira et al.

<p>Focusing on the aftermath of the abduction, rape and killing of an 8-year-old girl in Vitória, the paper argues that the violent event has left various traces that index a necropolitical power formation oriented towards hegemonic political and economic actors. The traces range from physical marks of violence to indications of obfuscation and manifestations of support for the aggressors. Such support was expressed, for example, by the city council's vote to retain a street name that honours the family of one of the alleged perpetrators. To analyse necropolitics through such traces, we draw on Mitchell Dean's discussion of the “signature of power” alongside works on feminicide, counter-forensics and contested toponymy. Thus reading necropolitics through its signature, we argue, sheds light on its specific context of formation and allows for scrutinizing the specific strategies and material elements through which necropolitics unfolds its deadly effects.</p>

Assessment of UAV image quality in terms of optical resolution

P. Zachar, Ł. Wilk, M. Pilarska-Mazurek et al.

The aim of this study was to assess the quality of images from different UAV sensors in terms of their optical resolution, expressed by the MTF10 parameter. The study was conducted for four cameras: Mavic 3E, Matrice 4E, Phantom 4 RTK and Zenmuse P1, under different weather and lighting conditions, with varying flight altitudes and ISO settings. The Siemens Star pattern and ResolvingPower software provided by The German Aerospace Center (DLR) were used in the analysis. The results showed a significant effect of flight altitude, time of day and ISO sensitivity on image quality. A decrease in sharpness (MTF10) was observed with increasing distance from the image centre and at higher ISO values. The conclusions of the study may be helpful in planning photogrammetric missions using UAVs, enabling better-quality image data.

Combining a ground-based UV network with satellite maps: A case study for Germany

Barbara Klotz, Verena Schenzinger, Michael Schwarzmann et al.

A study for the comprehensive information of current UV exposure for the area of Germany, based on the method for near real time calculation of UV Index maps used in the framework of the Austrian UV Monitoring Network, is presented. For the area of Germany about 22.000 surface UV Index maps were calculated for the year 2022 via the radiative transfer model libRadtran by incorporating daily forecast data for ozone, albedo and aerosols from the Copernicus Atmospheric Monitoring Service and taking into account cloud information gathered from SEVIRI data of Meteosat Second Generation in the form of a cloud modification factor. Ground-based measurements of 17 stations of the German Solar Monitoring Network were then compared to the modelled maps. For most stations the correlation coefficient between measured and modelled UV Index (UVI) is above 0.92 and the mean difference of modelled UVI to measured UVI is smaller than 0.5 UVI. The modelling of the UVI at the high mountain station Schneefernerhaus is associated with higher uncertainties (correlation coefficient 0.85 and mean UVI difference 0.6 UVI) due to the small-scale topography with spatially highly variable albedo and clouds. Moreover, case studies for specific locations with respect to cloud conditions and topography are discussed, as well as a case study of the combination of ground-based measurements and modelled UVI maps in form of spatial correction factors.

Cultural Dimensions of AI Perception: Charting Expectations, Risks, Benefits, Tradeoffs, and Value in Germany and China

Philipp Brauner, Felix Glawe, Gian Luca Liehner et al.

As artificial intelligence (AI) continues to advance, understanding public perceptions -- including biases, risks, and benefits -- is essential for guiding research priorities and AI alignment, shaping public discourse, and informing policy. This exploratory study investigates cultural differences in mental models of AI using 71 imaginaries of AI's potential futures. Drawing on cross-cultural convenience samples from Germany (N=52) and China (N=60), we identify significant differences in expectations, evaluations, and risk-benefit tradeoffs. Participants from Germany generally provided more cautious assessments, whereas participants from China expressed greater optimism regarding AI's societal benefits. Chinese participants exhibited relatively balanced risk-benefit tradeoffs ($β=-0.463$ for risk and $β=+0.484$ for benefit, $r^2=.630$). In contrast, German participants placed greater emphasis on AI's benefits and comparatively less on risks ($β=-0.337$ for risk and $β=+0.715$ for benefit, $r^2=.839$). Visual cognitive maps illustrate these contrasts, offering new perspectives on how cultural contexts shape AI acceptance. Our findings highlight key factors influencing public perception and provide insights for aligning AI with societal values and promoting equitable and culturally sensitive integration of AI technologies.

A new understanding on the history of developing MRI for cancer detection

Donald C. Chang

Science is about facts and truth. Yet sometimes the truth and facts are not obvious. For example, in the field of MRI (Magnetic Resonance Imaging), there has been a long-lasting debate about who were the major contributors in its development. Particularly, there was a strong dispute between the followers of two scientists, R. Damadian and P. Lauterbur. In this review, we carefully trace the major developments in applying NMR for cancer detection starting almost 50 years ago. The research records show that the truth was beyond the claims of either research camps. The development of NMR for cancer detection involved multiple research groups, who made critical contributions at different junctures.

Museums and Geoconservation

Michael J. Benton, Sarah King

While museums have long been associated with the protection and interpretation of cultural, historical, and natural heritage, their role in geoconservation has only become more prominent in recent decades. Geoconservation focuses on the conservation of geological features, processes, and landscapes, and has gained recognition as an important area of environmental protection, particularly in the context of climate change and anthropogenic pressures on natural resources. Importantly, geoconservation is based on the fundamental scientific evaluation of those locations, such as open landscapes, coastlines, and quarries in terms of their regional and international significance. Therefore, there are two roles for museums in connection with geoconservation, namely scientific and educational. Museums promote geoconservation through their collections, exhibitions, research, and public outreach. Different papers in the volume address questions of proper collecting practice and making links from the conserved geological sites to the curated collections in a museum, largely in the context of their scientific worth. Collecting on the land can be a fraught topic in the context of moving specimens from place to place, especially in moving them from one nation to another. What was once done without thought is now an important area of ethical debate. Such considerations are important also in education, where the choice of language and terminology can matter. Further, museums, like geoparks, rely on the support of visitors and it is important for all audiences to be considered in planning the educational and engagement activities in museums and integrating with nearby geosites. Partnerships between museums and geosites can present benefits for both. Papers in the Special Issue We publish 11 papers in this Special Issue, addressing different topics in the relationship of museums with geoconservation sites and objectives. Our authors come from many countries (UK, Germany, France, Morocco, Australia, and China) and reflect specific examples from each of these nations. In two articles, the authors explore practical, legal, and ethical issues between geological sites and museums. Van Geert (2024) compares the presentation of geology in geopark museums and natural history museums, focusing on the French and Spanish Catalan region of Europe. He notes how the expansion of the geoheritage concept has led to profound changes in museums and the wider heritage sector as these institutions adapt to strengthening the link between natural and cultural heritage. He also sees real impacts from increasing awareness among professionals and the public for issues associated with decolonization issues and the climate crisis. In their paper, Reedman et al. (2024) explore fossil collecting along parts of the Dorset and East Devon Coast World Heritage Site. Fossil collecting is managed through codes of conduct rather than laws. The codes operate on rapidly eroding coastlines where fossils may be found at any time and if they are not collected might be lost to erosion. This makes it impractical to mandate official collecting by licensed authorities only because they do not have the time to monitor many kilometers of coastline every few days. On the other hand, the hundreds of thousands of visitors could cause great harm by over-collecting and dispersing the fossils. A balance is struck, whereby visitors may collect common fossils such as ammonites, but are encouraged to report any particularly impressive specimens or marine reptile bones. It is unknown how many remarkable fossils are removed without being recorded, but sufficient specimens are recorded by the local museums along the coast that the authors conclude the codes of good practice are at least substantially effective. Two papers, respectively from the UK and Australia, explore issues of decolonization and current issues between occupants of the land. Gelsthorpe (2024) provides a thoughtful consideration of decolonization as it affects a museum, in his case the Manchester Museum, that acquired specimens from all over the world in times when few questions were asked about ethical matters. He argues that ‘the repatriation of geological specimens can be regarded as a barometer of the progress of decolonization’. He provides an example of how the Manchester Museum returned a Cretaceous fossil bird specimen that had been purchased illegally to China and uses this as a wake-up call to encourage other museums to be proactive in contacting authorities in other nations to offer the return of specimens. Hurst et al. (2024) explore live situations in Australia where scientists and museums have up to now often ignored the wishes and interests of the First Nations peoples. They note that museums in Australia, and more widely, exhibit numerous examples of First Nations art, and ethical considerations about how those artifacts were obtained and how they are exhibited and explained can be enormous. There are also major concerns ignored to a large extent hitherto about the land throughout Australia and how we approach and talk about it. Every geological site is on the ancestral lands of a First Nations group, and Hurst et al. present ideas about proper engagement between Western-trained scientists and First Nations peoples. Sally Hurst pioneered an engagement scheme throughout Australia called ‘Found a Fossil’ survey, and the authors present results and examples of further outcomes between museums and geosites concerning dinosaur tracks, stone tools, and a film project that have brought together disparate interests and cultures around important geological themes. We then present five articles that provide examples of different means of illustrating and disseminating information about geosites through museums. El Hamidy et al. (2024) show the National Ceramics Museum in Safi, Morocco (NCMSM) helps to promote geotourism and protect geosites through a variety of activities, including geosite visits, educational programs, interpretive panels, geotours, awareness campaigns, souvenir offers, and interactive applications. Lincoln and Colley (2024) provide an account of how a small geological museum in northern England, the Kendal Museum, used stories around some ‘local heroes’ to interest the local people and visitors in how geologists work and to make connections from the museum displays to local geosites that tourists can visit. In a similar way, Munt (2024) reports the history of a newer museum, the Dinosaur Isle Museum on the Isle of Wight, southern England, founded in 2001, and how it exhibits dinosaur fossils all found within at most a few kilometers of the museum. He argues that place is important in the location of this museum, allowing visitors and local people to realize the remarkable specimens on show are very local to the museum itself, and inspiring some at least to walk or drive on to see some of the original find spots of dinosaur skeletons and footprints. The fourth case study is from the IVPP museum in Beijing, China, where Wang et al. (2024) present a detailed account of the great wall murals that act as a backdrop to the collections on all three floors of the galleries. They show how they are a good representation of the state of knowledge of Chinese palaeontology in the early 1990s, and how the life restorations of animals can help visitors interpret the fossils they see in front of them and connect those back to the sites from which they came, many of them now incorporated into geoparks that are open to visitors. Finally, in this section, Schütrumpf et al. (2024) describe the ‘Ask a Geologist’ service at the Warwick Market Hall Museum in central England, where staff of the museum and volunteers from the county geoconservation group meet the public to answer questions and identify rocks and fossils. The final two articles are about one of the longest-studied geological areas in the world, the Dorset coast in southern England. Davis (2024) describes the Lyme Regis Fossil Festival which has happened each year since 2005, attracting 15–20,000 people each time to the variety of stalls, scientific lectures, circus shows, and other events designed to link people to the geology and palaeontology and especially the geoconservation aspects of the Jurassic Coast World Heritage site. It all began with Mary Anning (1799–1847), and Pearson (2024) presents an evocative account of her involvement in the campaign to establish a statue in honor of the great fossil collector. In particular, she describes how Mary Anning has become a hero worldwide for her contributions and acts as an inspiration for young people, especially girls, to become scientists, but also to take an interest in geology, palaeontology, and geoconservation.

The social philosophy of German romanticism

Lomako, Olga М.

Introducton. The article is devoted to the analysis of German Romanticism through a social philosophical examination of its origin, features and methodological foundations in the historical and cultural context. Theoretical analysis. It is proposed to consider the analysis and methodology of German Romanticism using the philosophical method of genealogy. The genealogical procedure is heterogeneous in its essence, since it involves the identification of the duality of the beginning, the source of sociality. In the romantic worldview, this is the fusion of aesthetic perception and conceptual thinking. It is established that the philosophical methodological foundations of German Romanticism are laid by the German idealistic transcendental philosophy (Kant and Schelling) in the unity of epistemological, aesthetic and anthropological aspects. Empirical analysis. Genealogical understanding of the specific social conditions in Germany at the end of the XVIII-early XIX centuries allowed us to identify the primary concept of the German romantic worldview as the source of sociality &ndash; free sociability &ndash; and to defi ne its multidimensional nature as understanding and recognition of the Other (rules of conduct and communication, creation of programs of eternal peace, interest in history and folk language). The foundation of the University of Berlin becomes the academic realization of the concept of free sociability. Conclusion. It is concluded that the goal of early German Romanticism &ndash; free sociability as a new form of human solidarity &ndash; long determined the humanistic orientation of the romantic worldview.

Parental perceptions of informed consent in a study of tracheal intubations in neonatal intensive care

Susanne Tippmann, Janine Schäfer, Christine Arnold et al.

Background and objectiveObtaining informed consent in neonatal emergency research is challenging. The aim of this study was to assess parental perceptions of informed consent following participation in a clinical trial in neonatal emergency care.MethodsThis was a supplementary analysis of a randomised controlled trial comparing video and direct laryngoscopy for neonatal endotracheal intubation in the delivery room and neonatal intensive care unit. After obtaining informed consent for the clinical trial, parents were asked to answer a series of self-administered questions about their perceptions of clinical trial participation and the consent process. Informed consent had been given either before birth, after birth but before inclusion in the trial, or after inclusion in the trial.ResultsWe received responses from 33 mothers and 27 fathers (n = 60) of the 63 preterm and term infants who participated in the study. Fifty-three (89.8%, n = 59) parents agreed that infants should participate in clinical trials, and 51 (85%, n = 60) parents agreed that parents should be asked for informed consent. Fifty-three (89.8%, n = 59) parents felt that their infant's participation in this particular trial would be beneficial. Fifty-two (86.7%, n = 60) parents felt that the informed consent process was satisfactory. One parent (100%, n = 1) approached before birth, 23 parents (82.1%, n = 28) approached after birth but before enrolment and 26 (83.9%, n = 31) parents approached after enrolment were satisfied with the timing of the consent process. Eight (13.3%, n = 60) parents felt some pressure to provide informed consent. Of these, two (25%) were approached before enrolment and six (75%) were approached after enrolment.ConclusionParents valued their infant's participation in an emergency neonatal clinical trial and considered it important to be asked for consent. In this study, it seemed less important whether consent was obtained before or after the intervention. Future studies may need to investigate which form of consent is most acceptable to parents for the individual study in question.

SOVIET-GERMAN NEGOTIATIONS ABOUT THE FATE OF THE BLACK SEA FLEET SHIPS THAT RETURNED TO SEVASTOPOL IN 1918

Vatlin A.Yu.

In the tragedy of the Russian Black Sea Fleet drowned near Novorossiysk due to the threat of capture by Germany, the return of several ships to German-occupied Sevastopol remains the little-known page of history. The further fate of the ships themselves, with their crews including their possible participation in the military operations on the side of Central Powers was being resolved during the negotiations between Moscow and Berlin right up to October 1918 as it was one of the components of the Soviet - German relations after Brest-Litovsk Peace Treaty.The Soviet Russia Plenipotentiary mission in Berlin, which began its work after the signing of the Brest Treaty, played a key role in the negotiations. A.A. Ioffe, who headed it, arrived in Germany at the end of April and immediately began to resolve the conflict related to the occupation of Crimea and the withdrawal of ships of the Black Sea Fleet from Sevastopol. Their fate was given special attention in the Extension Treaty between Russia and Germany, which provided for the possibility of their use against the Triple Entente fleet in the Black Sea. The curtailment of military operations on land and the signing of the Armistice of 11 November 1918 put an end to the fate of the ships that returned to Sevastopol. They were transferred by the Triple Entente to the white armies that controlled the South of the former Russian Empire.

Phylogenetic diversity and the structure of host-epiphyte interactions across the Neotropics

Marcio R. Pie, Fernanda S. Caron, Thom Dallimore et al.

Understanding the mechanisms driving community assembly has been a major focus of ecological research for nearly a century, yet little is known about these mechanisms in commensal communities, particularly with respect to their historical/evolutionary components. Here, we use a large-scale dataset of 4,440 vascular plant species to explore the relationship between the evolutionary distinctiveness (ED) (as measured by the ’species evolutionary history’ (SEH)) of host species and the phylogenetic diversity (PD) of their associated epiphyte species. Although there was considerable variation across hosts and their associated epiphyte species, they were largely unrelated to host SEH. Our results mostly support the idea that the determinants of epiphyte colonization success might involve host characteristics that are unrelated to host SEH (e.g., architectural differences between hosts). While determinants of PD of epiphyte assemblages are poorly known, they do not appear to be related to the evolutionary history of host species. Instead, they might be better explained by neutral processes of colonization and extinction. However, the high level of phylogenetic signal in epiphyte PD (independent of SEH) suggests it might still be influenced by yet unrecognized evolutionary determinants. This study highlights how little is still known about the phylogenetic determinants of epiphyte communities.

From species descriptions to diversity patterns: the validation of taxonomic data as a keystone for ant diversity studies reproducibility and accuracy

Rodrigo M. Feitosa, Thiago S. R. Silva, Gabriela P. Camacho et al.

Research findings in natural sciences need to be comparable and reproducible to effectively improve our understanding of ecological and behavioural patterns. In this sense, knowledge frontiers in biodiversity studies are directly tied to taxonomic research, especially in species-rich tropical regions. Here we analysed the taxonomic information available in 470 studies on Brazilian ant diversity published in the last 50 years. We aimed to quantify the proportion of studies that provide enough data to validate taxonomic identification, explore the frequency of studies that properly acknowledge their taxonomic background, and investigate the primary resources for ant identification in Brazil. We found that most studies on Brazilian ant diversity (73.6%) explicitly stated the methods used to identify their specimens. However, the proportion of papers that provide complete data for the repository institutions and vouchered specimens is vanishingly small (5.8%). Additionally, only 40.0% of the studies consistently presented taxon authorities and years of description, rarely referencing taxonomic publications correctly. In turn, the number of specialists and institutions consulted for ant identification in Brazil has increased in the last years, along with the number of studies that explicitly provide their taxonomic procedures for ant identification. Our findings highlight a shift between generations regarding the recognition of taxonomy as fundamental science, deepening our understanding of biodiversity.

Growth and Public Health Concerns

Michael Hermanussen, Christiane Scheffler, Liza Wilke et al.

Seventeen scientists met for this year’s conference on Auxology held at Krobielowice castle, Poland, to discuss growth and public health concerns. The regulation of growth is complex and besides metabolic and endocrine components including hypothalamic releasing factors, growth hormone and multiple downstream effectors, comprises the full spectrum of the psychosocial, economic and emotional environment including signaling dominance, competence, prestige, or subordination and indulgence, all of this being sensitive to urban or rural lifestyle, the political climate and with marked plasticity throughout history. New statistical techniques (St. Nicolas House Analysis) are presented for analyzing anthropometric variables for public health concerns. The impact of spatial differences on developmental tempo, growth in height, and the prevalence of childhood obesity are discussed as well as the impact of social mobility on obesity, and the benefits of the biopsychosocial status when getting along with socio-economic disasters and the COVID-19 pandemic.

Fossilization of Precambrian microfossils in the Volyn pegmatite, Ukraine

G. Franz, P. Lyckberg, V. Khomenko et al.

<p>We report on Precambrian microfossils from igneous rocks of the Volyn pegmatite district, associated with the Paleoproterozoic Korosten pluton, northwestern Ukraine. The fossils were recovered from meter-sized miarolitic cavities and show a well-preserved 3D morphology, mostly filamentous but with a large variety of types and also in irregular, flaky shapes reminiscent of former biofilms, as well as rare spherical objects. Based on literature data, pyrolysis experiments, and reflected light microscopy results, the organic matter (OM) is characterized as (oxy-)kerite. Further investigations with microscopic techniques, including scanning and transmission electron microscopy, and electron microprobe analysis show that fossilization likely occurred during a hydrothermal, post-pegmatitic event by silicification dominantly in the outermost 1–2 <span class="inline-formula">µm</span> of the microfossils. The hydrothermal fluid, derived from the pegmatitic environment, was enriched in <span class="inline-formula">SiF<sub>4</sub></span>, Al, Ca, Na, K, Cl, and S. The OM shows O enrichment in which N and S content is low, indicating simultaneous N and S loss during anaerobic oxidation. Mineralization with Al silicates starts at the rim of the microfossils, continuing in its outer parts into identifiable encrustations and intergrowths of clay minerals, feldspar, Ca sulfate, Ca phosphate, Fe sulfide, and fluorite.</p> <p>Breccias, formed during collapse of some the miarolitic cavities, contain decaying OM, which released high concentrations of dissolved <span class="inline-formula"><math xmlns="http://www.w3.org/1998/Math/MathML" id="M3" display="inline" overflow="scroll" dspmath="mathml"><mrow class="chem"><msup><msub><mi mathvariant="normal">NH</mi><mn mathvariant="normal">4</mn></msub><mo>+</mo></msup></mrow></math><span><svg:svg xmlns:svg="http://www.w3.org/2000/svg" width="29pt" height="14pt" class="svg-formula" dspmath="mathimg" md5hash="47abf32743cd28df9573e01430c76658"><svg:image xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="bg-19-1795-2022-ie00001.svg" width="29pt" height="14pt" src="bg-19-1795-2022-ie00001.png"/></svg:svg></span></span>, responsible for the late-stage formation of tobelite-rich muscovite and buddingtonite.

As the geological environment for the growth of the microorganisms and fossilization, we assume a geyser system in which the essential biological components C, N, S, and P for growth of the organisms in the miarolitic cavities were derived from microorganisms at the surface. Fossilization was induced by magmatic <span class="inline-formula">SiF<sub>4</sub></span>-rich fluids. The Volyn occurrence is a distinct and uncommon example of Precambrian fossils, and the results underline the importance of cavities in granitic rocks as a possible habitat for microorganisms preserved in the deep biosphere.</p>

COVID-19 propagation by diffusion -- a two-dimensional approach for Germany

Guenter Bärwolff

Diffusion comes anytime and everywhere. If there is a gradient or a potential difference of a quantity a diffusion process happens and this ends if an equilibrium is reached only. The concentration of a species maybe such quantity, or the voltage. An electric currant will be driven by a voltage difference for example. In this COVID-19 pandemic one observes both regions with low incidence and other ones with high incidence. The local different people density could be a reason for that. In populous areas like big cities or congested urban areas higher COVID-19 incidences could be observed than in rural regions. The aim of this paper consists in the application of a diffusion concept to describe one possible issue of the the COVID-19 propagation. This will be discussed for the German situation based on the quite different incidence data for the different federal states of Germany.

Two proto-science-fiction novels written in French by 18th century women

Yael Naze

With Cyrano, Voltaire, and Verne, France provided important milestones in the history of early science fiction. However, even if the genre was not very common a few centuries ago, there were numerous additional contributions by French-speaking writers. In this paper, we review two cases of interplanetary novels written in the second half of the eighteenth century and sharing a rare particularity: their authors were female. Voyages de Milord Ceton was imagined by Marie-Anne de Roumier-Robert whereas Cornelie Wouters de Wasse conceived Le Char Volant. While their personal lives were very different, and their writing style too, both authors share in these novels a common philosophy in which equality -- between ranks but also between genders -- takes an important place. Their works thus clearly fit into the context of the Enlightenment.
