Grounding force-directed network layouts with latent space models
Authors: Gaisbauer Felix , Pournaki Armin , Banisch Sven , Olbrich Eckehard 
Published: May 2023

AbstractForce-directed layout algorithms are ubiquitously used tools for network visualization. However, existing algorithms either lack clear interpretation, or they are based on techniques of dimensionality reduction which simply seek to preserve network-immanent topological features, such as geodesic distance. We propose an alternative layout algorithm. The forces of the algorithm are derived from latent space models, which assume that the probability of nodes forming a tie depends on their distance in an unobserved latent space. As opposed to previous approaches, this grounds the algorithm in a plausible interaction mechanism. The forces infer positions which maximise the likelihood of the given network under the latent space model. We implement these forces for unweighted, multi-tie, and weighted networks. We then showcase the algorithm by applying it to Facebook friendship, and Twitter follower and retweet networks; we also explore the possibility of visualizing data traditionally not seen as network data, such as survey data. Comparison to existing layout algorithms reveals that node groups are placed in similar configurations, while said algorithms show a stronger intra-cluster separation of nodes, as well as a tendency to separate clusters more strongly in multi-tie networks, such as Twitter retweet networks.

AbstractA two-dimensional nanostructure composed of Ag2O nanobranches attached to TiO2 hollow nanofibres (denoted as 2D Ag2O/TiO2) was successfully prepared via sol–gel and coaxial electrospinning techniques. The Ag/TiO2 hollow nanofibres were fabricated and calcined in ambient air at 500 °C. By calcination, the removal of organic materials and the formation of anatase TiO2 were achieved with a well-retained hollow structure. The embedded Ag nanoparticles functioned as seeds for the Ag2O outgrowth on the TiO2 surface using a hydrothermal treatment at different times and temperatures, which caused the change in physical appearance, surface area, and electrical conductivity of 2D Ag2O/TiO2. A high quantity of Ag2O nanobranches on TiO2 nanofibres were obtained with increasing the temperature from 110 to 115 °C and the reaction time to 60 min. Consequently, the electrochemical active surface area (EASA) value was maximised to 65.25 cm2 per cm2 with an enhanced electrical conductivity of 91.3 ± 3.9 × 10−2 S cm−1. Further studies on the depth-profiles of Ag, Ti, and O revealed the presence of Ag2O attached to the core structure of TiO2. The photoelectrochemical and photocatalytic tests confirmed the excellent physical and electrochemical properties of 2D Ag2O/TiO2 (@115 °C, 60 min) for use in energy and environmental applications.

AbstractCiliates in the class Prostomatea play an important role in the global microbial loop due to their significant abundances and broad feeding strategies at the foundation of food webs. Despite their importance in ecosystems, the taxonomy and systematics of this group of ciliates has long been poorly understood, with this being especially true for members of the family Lagynusidae. Here we examine four lagynusids collected from sandy beaches in China, using silver-staining and 18S rRNA gene sequencing techniques. These investigations revealed two new genera and two new species and provided details for two little known forms: Penardella marina gen. nov., sp. nov., Apolagynus cucumis (as reported by Penard. Études sur les infusoires d’eau douce. Georg and Cie, Genève, 1922) gen. nov., comb. nov., Lagynus minutus sp. nov., and Lagynus elegans (Engelmann in Z Wiss Zool 11:347–393, 1862) Quennerstedt (Acta Univ Lund 4:1–48, 1867). Penardella gen. nov. can be morphologically distinguished by having more than three dikinetidal perioral kineties. Apolagynus gen. nov. differs from the closely related genus Lagynus in the absence of a conspicuous neck-like region. The ciliature of Apolagynus cucumis is revealed here for the first time, which demonstrates the classification of this species within Lagynusidae. Furthermore, Apolagynus binucleatus (Jiang et al., 2021) comb. nov. is established according to the new finding. The results of our phylogenetic analyses based on the 18S rRNA gene support the establishment of two new genera and indicate that Lagynusidae is monophyletic, which further strengthens its valid taxonomic status.

AbstractThe Nb2CTx prepared by hydrothermal-assisted in-situ HF generation etching was investigated in terms of its gas sensor performance. The Nb2CTx was obtained by mixing Nb2AlC with pure water, hydrochloric acid, and fluoride (LiF or NH4F) and then hydrothermally treated at 180 °C for 24 h. This in-situ HF generation etching by hydrothermal treatment was more efficient and safer in the synthesis of the Nb2CTx than the direct HF etching. The Nb2CTx etched with LiF had relatively wide interlayer spacing because the hydration radius of Li+ was larger than that of NH4+. The results also suggest that Nb2O5 is formed during the synthesis process. These results suggest that interlayer spacing, surface termination, and secondary phases formation can be controlled by the etchant, and that hydrothermal treatment extended the applicability of insoluble etchants. The Nb2CTx synthesized with LiF was evaluated as a gas sensor at room temperature in air in the presence of designated concentrations of 6 different gases, which exhibited good sensitivity and repeatability and fast recovery time, except for NH3. Hydrothermal-assisted etching contributed to providing sufficient interlayer spacing for the gas response without an exfoliation process.
Urgency through education: Futures learning through children’s literature
Authors: Auld Glenn , O’Mara Joanne , White Peta J. 
Published: May 2023

AbstractThe purpose of this communication is to explore possibilities for children’s literature to enable futures learning. It introduces the ways in which two different frameworks might be used to analyse children’s literature. The first framework draws upon the Earth Charter Principles (ECP) (Auld et al., 2021). The second framework brings together the pillars of sustainability with the principles of Education for Sustainability (EfS) in a framework for ecological sustainability of children’s literature (White et al., 2020). The communication starts by introducing a text – a recent example of ‘awarded’ and therefore high-quality children’s literature. We then outline the two frameworks and explore the possibilities of applying these frames for analysing this text. We conclude that the sustainability frameworks are useful tools and resources for analysing children’s literature to determine the quality of the text and how the experience of reading the text may impact children, their learning and their environmental consciousness and practices.
Give what is required and take only what you need! The effect of framing on rule-breaking in social dilemmas
Authors: Wyszynski Marc , Bauer Alexander Max 
Published: May 2023

AbstractTo investigate the impact of framing on rule-breaking in social dilemmas, we incorporated a rule in a 1-shot resource game with 2 framing treatments: in one frame, we offered a give-some dilemma (i.e., a variant of a public goods game), and in the other frame, a take-some dilemma (i.e., a variant of a commons dilemma game). In each frame, all participants were part of 1 single collective sharing a common good. Each participant was initially equipped with 1 of 5 different endowments of points from which they must give/were allowed to take amounts to/from the common good. The rule established outcome equality between participants by prescribing the exact amounts of what to give/take to/from the common good, which was finally divided equally among participants. Participants decided whether to cooperate and comply with the rule or to break the rule to their own advantage and to the detriment of the collective (i.e., giving lower/taking higher amounts). The results of an online experiment with 202 participants showed a significantly higher proportion of individuals breaking the rule in the take-some dilemma than in the give-some dilemma. In addition, endowment size influenced the proportion of rule-breaking behavior in the take-some dilemma. However, the average amounts of points not given/taken too much were not different between the 2 dilemma types.
Detection of crevassed areas with minimum geometric information: Vernagtferner case study
Authors: Dobler Theresa , Hagg Wilfried , Mayer Christoph 
Published: May 2023

AbstractCrevasses pose severe risks for mountaineers and field glaciologists. Smaller cracks between 0.5 and 2 m are still dangerous, but often not visible in medium resolution satellite imagery. If they are snow covered, they are completely undetectable by optical sensors. We set out to develop an approach to detect potentially crevassed areas by a minimum of geometric data, and to make the method generally applicable to glacier regions. On Vernagtferner, we compared a reference dataset of crevasses observed in high-resolution optical imagery with the curvature of the ice surface and the spatial gradients in driving stress. Both parameters can be derived from a digital surface model and a bedrock model, derived from ice thickness measurements. The correlation patterns show that crevasses preferably form in convex areas and in areas where the driving stress rapidly increases. This corresponds with the theory of crevasse formation. Although the method still misclassifies larger parts, the approach has the potential to define probable non-crevassed areas as well as to aid the planning of safe routes.
Sensitivity to syntactic dependency formation in child second language processing: a study of numeral quantifiers in Korean
Authors: Kim Hyunwoo , Kim Kitaek , Jo Kyuhee , Hwang Haerim 
Published: May 2023

AbstractThis study investigates whether child second language (L2) learners can use syntactic information during the processing of sentences involving unbounded dependencies and how their processing patterns compare to those of child monolinguals and adult L2 learners. Through a self-paced reading experiment involving the numeral quantifier (NQ) construction in Korean, we tested participants’ sensitivity to agreement violations between a noun phrase (NP) and an NQ in local and nonlocal conditions. The results showed that a subset of child L2 learners who demonstrated target-like knowledge of NP-NQ agreement in an offline task spent a longer processing time in the NP-NQ mismatch than in the NP-NQ match condition, in both local and nonlocal contexts. These child L2 learners’ processing patterns were comparable to those observed in child monolinguals and adult L2 learners. These findings suggest that child and adult L2 learners rely on the same system of syntactic representations and processing mechanisms that guide first language processing.
Relative oversampling of carbonate rocks in the North American marine fossil record
Authors: Balseiro Diego , Powell Matthew G. 
Published: May 2023

AbstractPaleontologists have long stressed the need to know how sampling the fossil record might influence our knowledge of the evolution of life. Here, we combine fossil occurrences of North American marine invertebrates from the Paleobiology Database with lithologic data from Macrostrat to identify sampling patterns in carbonate and siliciclastic rocks. We aim to quantify temporal trends in sampling effort within and between lithologies, focusing on the proportion of total available volume that has been sampled (sampled fossiliferous proportion, here called κ). Results indicate that the sampled fossiliferous proportion was stable during the Paleozoic, and variable during the post-Paleozoic, but showed no systematic increase through time. Fossiliferous carbonate rocks are proportionally more sampled than siliciclastic rocks, with intervals where the carbonate κ is double the siliciclastic κ. Among possible explanations for the apparent oversampling of fossiliferous carbonate rocks, analyses suggest that barren units, taphonomic dissolution, or data entry errors cannot completely explain sampling patterns. Our results suggest that one of the important drivers might be that paleontologists publish taxonomic descriptions from carbonate rocks more frequently. The higher diversity in carbonate rocks might account for an ease in the description of unknown species and therefore a higher rate of published fossils. Finally, a strong effect in favor of carbonate rocks might distort our perception of diversity through time, even under commonly used standardization methods. Our results also confirm that previous descriptions of an increase in the proportion of sampled fossiliferous rocks over time were driven by the sampling of the nonmarine fossil record.
Selenium deficiency-induced high concentration of reactive oxygen species restricts hypertrophic growth of skeletal muscle in juvenile zebrafish by suppressing TORC1-mediated protein synthesis

AbstractSe deficiency causes impaired growth of fish skeletal muscle due to the retarded hypertrophy of muscle fibres. However, the inner mechanisms remain unclear. According to our previous researches, we infer this phenomenon is associated with Se deficiency-induced high concentration of reactive oxygen species (ROS), which could suppress the target of rapamycin complex 1 (TORC1) pathway-mediated protein synthesis by inhibiting protein kinase B (Akt), an upstream protein of TORC1. To test this hypothesis, juvenile zebrafish (45 d post-fertilisation) were fed a basal Se-adequate diet or a basal Se-deficient diet or them supplemented with an antioxidant (DL-α-tocopherol acetate, designed as VE) or a TOR activator (MHY1485) for 30 d. Zebrafish fed Se-deficient diets exhibited a clear Se-deficient status in skeletal muscle, which was not influenced by dietary VE and MHY1485. Se deficiency significantly elevated ROS concentrations, inhibited Akt activity and TORC1 pathway, suppressed protein synthesis in skeletal muscle, and impaired hypertrophy of skeletal muscle fibres. However, these negative effects of Se deficiency were partly (except that on ROS concentration) alleviated by dietary MHY1485 and completely alleviated by dietary VE. These data strongly support our speculation that Se deficiency-induced high concentration of ROS exerts a clear inhibiting effect on TORC1 pathway-mediated protein synthesis by regulating Akt activity, thereby restricting the hypertrophy of skeletal muscle fibres in fish. Our findings provide a mechanistic explanation for Se deficiency-caused retardation of fish skeletal muscle growth, contributing to a better understanding of the nutritional necessity and regulatory mechanisms of Se in fish muscle physiology.

Published: May 2023

AbstractGiardiasis, caused byGiardia duodenalis, is a leading cause of diarrhoea in resource-poor countries. To gain a better insight into the epidemiology ofGiardiain Africa, we undertook a robust study to comprehend the distribution and prevalence ofGiardiainfection in humans, animals and their dispersal in the environment. Our protocol was registered with PROSPERO (registration number CRD42022317653). Deep literature search from 5 electronic databases, namely, AJOL, Google scholar, PubMed, ScienceDirect and Springer Link was performed using relevant keywords. Meta-analysis was performed using a random-effects model and heterogeneity among studies was evaluated using Cochran's Q and theI2-statistic. More than 500 eligible studies published from 1 January 1980 until 22 March 2022 were retrieved. In humans, exactly 48 124Giardiaspp. infection cases were registered from the 494 014 stool samples examined resulting in a pooled prevalence estimate (PPE) of 8.8% using microscopy. Whereas copro-antigen tests and molecular diagnostic methods generated PPE of 14.3 and 19.5%, respectively, with HIV+ subjects and those with diarrhoeatic stool having infection rates of 5.0 and 12.3%, respectively. The PPE ofGiardiaspp. infection in animals using molecular methods was 15.6%, which was most prevalent in pigs (25.2%) with Nigeria registering the highest prevalence at 20.1%. The PPE ofGiardiaspp. contamination from waterbodies was 11.9% from a total of 7950 samples which were detected using microscopy, with Tunisia documenting the highest infection rate of 37.3%. This meta-analysis highlights the necessity of ‘One Health’ approach for consolidated epidemiological studies and control of giardiasis in the African continent.

AbstractBackgroundNegative symptoms (avolition, anhedonia, asociality) are a prevalent symptom in those across the psychosis-spectrum and also occur at subclinical levels in the general population. Recent work has begun to examine how environmental contexts (e.g. locations) influence negative symptoms. However, limited work has evaluated how environments may contribute to negative symptoms among youth at clinical high risk for psychosis (CHR). The current study uses Ecological Momentary Assessment to assess how four environmental contexts (locations, activities, social interactions, social interaction method) impact state fluctuations in negative symptoms in CHR and healthy control (CN) participants.MethodsCHR youth (n= 116) and CN (n= 61) completed 8 daily surveys for 6 days assessing negative symptoms and contexts.ResultsMixed-effects modeling demonstrated that negative symptoms largely varied across contexts in both groups. CHR participants had higher negative symptoms than CN participants in most contexts, but groups had similar symptom reductions during recreational activities and phone call interactions. Among CHR participants, negative symptoms were elevated in several contexts, including studying/working, commuting, eating, running errands, and being at home.ConclusionsResults demonstrate that negative symptoms dynamically change across some contexts in CHR participants. Negative symptoms were more intact in some contexts, while other contexts, notably some used to promote functional recovery, may exacerbate negative symptoms in CHR. Findings suggest that environmental factors should be considered when understanding state fluctuations in negative symptoms among those at CHR participants.
India's epidemics in theRiḥlaof Ibn Baṭṭūṭa: plague, cholera or lexical muddle?
Authors: Tresso Claudia Maria 
Published: May 2023

AbstractThe famous Moroccan traveller Muḥammad b. Baṭṭūṭa, who left Tangier in 1325, claims to have made a journey that took him across most of the then Islamicate world. The country in which he recounts having stayed the longest was India, where he says he remained from 1333 to 1341/1342, mostly in the Islamic Sultanate of Delhi. A long section of hisRiḥlais dedicated to the sub-continent and modern historians of this region ascribe to it an important documentary value, although it has been argued that Ibn Baṭṭūṭa may have borrowed – not to imply copied – information from other sources in other parts of the work. As concerns India, Ibn Baṭṭūṭa speaks of two epidemics and one deadly disease that occurred in 1334–5 and 1344. Some scholars have referred to them as cholera, while others have suggested it was the plague – thus supporting the hypothesis that the medieval plague pandemic had struck India before reaching the Middle East. How did this confusion arise? What exactly does Ibn Baṭṭūṭa'sRiḥlarelate? Do Indo-Persian sources confirm these epidemics? Do they and/or Ibn Baṭṭūṭa'sRiḥlaallow us to discount the presence of the Medieval Plague in India, or rather do they assert it?In order to answer these questions, this paper analyses the information on the Indian epidemics in Ibn Baṭṭūṭa'sRiḥlaand compares the text with its translations in the principal European languages and with Indo-Persian chronicles. These analyses reveal something of a lexical muddle which, in my opinion, has contributed to some errors and misunderstandings regarding the diseases in question. But another question arises: is it possible to read the information provided by Ibn Baṭṭūṭa and the Indian chronicles in a consilient way, that is, taking into account not only the analysis of written documents, but also the recent and current findings in genetics of plague, and in particular on the Black Death? Finally, an attempt is made to answer a question that has to be asked, particularly in light of the criticism often levelled at Ibn Baṭṭūṭa. Considering that in one of these events he claims to have witnessed the epidemic, is there any reason to suppose that he did not? Regarding the other two events that he did not claim to witness firsthand, is there any cause to doubt his claims?
State inspection in contexts of cultural and sociopolitical conflict: The case of social services offered to Arab-Palestinian young women in Israel
Authors: Levin Lia , Karram-Elias Haneen , Pagorek Eshel Shira , Alnabilsy Raghda 
Published: May 2023

AbstractInspectors are the executing branch of state regulation. Existing literature focuses on their tasks and operations, mostly with regard to their commitments to the state and their complex relations with inspectees. The present study explores a heretofore-unexamined issue: the playing out of inspection in a sociopolitical context of national conflict and discriminatory majority-minority relations. Namely, it focuses on the work of inspectors of social services overseen by the Israeli welfare state but provided by local or contracted agencies, offered to one of the country’s most oppressed and marginalized populations: Arab-Palestinian young women. The research was based on interviews with 25 national and district inspectors in the field of services for young women in Israel, and reveals numerous barriers hindering effective inspection, resulting from having to inspect the implementation of universalist policy in a context of local needs; and the implementation of welfare policy in a context of national sociopolitical inequality. This is discussed in terms of the severe toll that color-blind and gender-blind policy can have on the feasibility of enforcing regulation, and on the potential to ensure that Arab-Palestinian young women receive adequate social services.
