Published: April 2023

The solar energy sector has grown rapidly in the past decades, addressing the issues of energy security and climate change. Many photovoltaic (PV) panels that were installed during this technological revolution, have accumulated as waste and even more are nearing their End-of-Life (EoL). Based on circular economy, a new hydrometallurgical process has been proposed for the management of the EoL PVs. This results in a chemical extract containing 0.7% w/w Ag, along with various other metals. This study investigates the MFC technology as an alternative method for valuable metal recovery from the chemical extract of PV panels. Moreover, metal recovery from the chemical extract is compared with the individual recoveries obtained using corresponding synthetic solutions. The results indicated that silver was completely recovered from the synthetic and the real chemical extract, with a rate of ~ 82 and ~ 32 μmol/h, respectively. The difference is attributed to the simultaneous reduction of other heavy metals in amorphous compounds, hindering the silver reduction kinetics and leading to a gradual electrode passivation. Nevertheless, silver can be 100% retrieved from the chemical extract, with a purity of 68–96% w/w (average 86% w/w), in crystal (face center cube) structure, containing minor metal impurities.

In this paper, we address core insights from Buddhist psychology about mind-body phenomena and the self, and we relate such insights to the notion of the self-pattern developed in the pattern theory of self. We emphasize the dynamic, temporal and enactive characteristics of the self-pattern, consistent with the core Buddhist notion of non-self. Although there is no one-to-one mapping of Buddhist psychological concepts onto the pattern theory of self, there are important similarities among such concepts and the various processes and dynamical relations that constitute a pragmatic self-pattern that can explain both experiences of self and non-self. Buddhist psychology and the notion of the self-pattern offer mutual insight into the processes, the dynamics, and the implications for questions about well-being and a flexibility that avoids anxiety and reduces attachment, craving, and suffering.

GIS-based flood risk assessment using multi-criteria decision analysis of Shebelle River Basin in southern Somalia
Authors: Osman Shuayb Abdinour , Das Jayanta
Published: April 2023

Floods are the most common and expensive natural calamity, affecting every country. Flooding in the Shebelle River Basin (SRB) in southern Somalia has posed a significant challenge to sustainable development. The main goal of this study was to analyze flood hazard, vulnerability and risk in the part of SRB using GIS-based Multi-Criteria Decision Analysis (MCDA). The flood hazard map was constructed using seven important causative factors: elevation, slope, drainage density, distance to river, rainfall, soil and geology. The results demonstrate that very low, low, moderate, high, and very high flood hazard zones correspond to 10.92%, 24.97%, 29.13%, 21.93% and 13.04% of the area of SRB, respectively. The flood vulnerability map was created using five spatial layers: land use/land cover, population density, distance to road, Global man-made impervious surface (GMIS), and Human built-up area settlement extent (HBASE). In addition, the results of the flood susceptibility and vulnerability maps were used to create a flood risk map. The results demonstrate that for the Shebelle River Basin, 27.6%, 30.9%, 23.6%, 12.1%, and 5.7% area correspond to very low, low, moderate, high, and very high flood risk zones, respectively. The Receiver Operating Characteristics-Area Under the Curve (ROC-AUC) of the flood hazard model exhibited a good prediction accuracy of 0.781. The majority of the basin is at risk of flooding in the very low, low, and moderate ranges; however, some tiny areas are at risk of flooding in the high and very high ranges. Flood hazard, vulnerability and risk maps should be provided and distributed the authorities responsible for flood protection so that people are aware flood risk locations.

Published: April 2023

Population growth and social and economic development demand increasing volumes of water for public supply, especially in scenarios where surface sources such as rivers may not meet the basic demands for the population. In southeastern Brazil, with emphasis on the Piracicaba region, there is a conflict over water use regarding agricultural and industrial activities, where the sugar-alcohol sector is widely highlighted. The region has thousands of hectares of sugarcane cultivated, which requires intensive use of fertilizers and pesticides, in addition to the need for large volumes of water in the production of sugar and ethanol, where the main effluent produced is represented by vinasse, used as fertilizer complement and soil hydration in sugarcane fields. This work presents the results of a geophysical diagnosis in a closed wetland, located in a sugarcane field region, to evaluate the hydrogeological function of this environment in aquifer recharge and the risks that land use can cause in the quality and availability of surface and underground water resources. The geophysical survey consisted of nine lines of electrical resistivity tomography in Schlumberger arrangement, submitted to 2D processing and inversion followed by interpolation and generation of 3D visualization models. The results indicate a direct connection between water accumulated in the wetland and the aquifer underneath, separated by an aquitard interface about 44 m thickness. The study points out to the high vulnerability to the input of pesticides and vinasse effluent from the surrounding sugarcane fields to the interior of the wetland, given the absence of riparian forest or buffer zone, in addition to the risk of contamination of surface and groundwater. Understanding the local hydrological dynamics should subsidize the sustainable use of the soil providing preservation of water resources, with emphasis on aquifers, a source of increasing importance in the face of the imminent scarcity of surface resources.

Published: April 2023

The Visual Question Answering (VQA) system is the process of finding useful information from images related to the question to answer the question correctly. It can be widely used in the fields of visual assistance, automated security surveillance, and intelligent interaction between robots and humans. However, the accuracy of VQA has not been ideal, and the main difficulty in its research is that the image features cannot well represent the scene and object information, and the text information cannot be fully represented. This paper used multi-scale feature extraction and fusion methods in the image feature characterization and text information representation sections of the VQA system, respectively to improve its accuracy. Firstly, aiming at the image feature representation problem, multi-scale feature extraction and fusion method were adopted, and the image features output of different network layers were extracted by a pre-trained deep neural network, and the optimal scheme of feature fusion method was found through experiments. Secondly, for the representation of sentences, a multi-scale feature method was introduced to characterize and fuse the word-level, phrase-level, and sentence-level features of sentences. Finally, the VQA model was improved using the multi-scale feature extraction and fusion method. The results show that the addition of multi-scale feature extraction and fusion improves the accuracy of the VQA model.

Published: April 2023

Objectives:

Access to patient information may affect how home-infusion surveillance staff identify central-line–associated bloodstream infections (CLABSIs). We characterized information hazards in home-infusion CLABSI surveillance and identified possible strategies to mitigate information hazards.

Design:

Qualitative study using semistructured interviews.

Setting and participants:

The study included 21 clinical staff members involved in CLABSI surveillance at 5 large home-infusion agencies covering 13 states and the District of Columbia. Methods: Interviews were conducted by 1 researcher. Transcripts were coded by 2 researchers; consensus was reached by discussion.

Results:

Data revealed the following barriers: information overload, information underload, information scatter, information conflict, and erroneous information. Respondents identified 5 strategies to mitigate information chaos: (1) engage information technology in developing reports; (2) develop streamlined processes for acquiring and sharing data among staff; (3) enable staff access to hospital electronic health records; (4) use a single, validated, home-infusion CLABSI surveillance definition; and (5) develop relationships between home-infusion surveillance staff and inpatient healthcare workers.

Conclusions:

Information chaos occurs in home-infusion CLABSI surveillance and may affect the development of accurate CLABSI rates in home-infusion therapy. Implementing strategies to minimize information chaos will enhance intra- and interteam collaborations in addition to improving patient-related outcomes.

We analyzed efficacy of a centralized surveillance infection prevention (CSIP) program in a healthcare system on healthcare-associated infection (HAI) rates amid the coronavirus disease 2019 (COVID-19) pandemic. HAI rates were variable in CSIP and non-CSIP facilities. Central-line–associated bloodstream infection (CLABSI), C. difficile infection (CSI), and surgical-site infection (SSI) rates were negatively correlated with COVID-19 intensity in CSIP facilities.
Enhancing the shelf life of injera: design of an evaporative cooler clay chamber derived from local clay in Bahir Dar, Ethiopia
Authors: Birhanu Gezahegn Asmare , Belay Alebel Nibret
Published: April 2023

Injera is Ethiopian ethnic traditional staple food, made from teff and other crops. The country’s superfoods are highly regarded in many Western countries for their excellent nutritional properties (‘very low gluten’), and mineral composition. Injera provides sufficient conditions for fungi to grow and ruin injera by changing the texture and making it inedible. This study aimed to develop an evaporative cooler clay chamber (ECCC) used to extend the shelf life of injera by controlling temperature and relative humidity (RH). This system is an economical and efficient way to lower the temperature and increase RH. The results show the maximum daily ambient temperature reduced from 28.98 °C to 22.90 °C and increased the RH of the storage chamber from 28.78% to 80.94%, respectively. The temperature drops up to 6.08 °C, and the RH rises to 52.16% observed. Additionally, the effects of temperature, RH and potential of hydrogen were studied for identified rotten injera and designed for injera storage. ECCC can store freshly made injera for 9 days before any visible mould stains appear, significantly reducing weight loss with an average cooling efficiency of 79.31%. Therefore, this study might help to develop low-cost cold storage for injera preservation at farms end in Ethiopia.
The Pedagogy of a Classroom for Intellectual Virtues
Authors: Smith Chris A.
Published: April 2023

Educating for intellectual virtue is a form of character education that aims for students to develop intellectual virtues, such as intellectual courage, humility, tenacity, honesty, curiosity, attentiveness, and open-mindedness. Recently, Kotzee et al. (2021) argued that ‘the intellectual virtues approach does not have available a suitably effective pedagogy to qualify the acquisition of intellectual virtue as the primary aim of education’ (p. 1). In this article, partly as a response to Kotzee et al.'s (2021) challenge and partly to better understand and shape the intellectual virtues classroom, I explore at a pedagogical and epistemological level two theories I believe to be evident in the intellectual virtues classroom: virtue responsibilism and social constructivism. Through bringing these theories into conversation, I argue that a deeper understanding of the intellectual virtues classroom is elicited which is able to overcome Kotzee et al.'s (2021) pedagogical challenge for the intellectual virtues approach.

Published: April 2023

Objective:

In this study, we described the first results of a surveillance system for infections associated with long-term central venous catheters (LT-CVC) in patients under outpatient chemotherapy.

Design:

This was a multicentric, prospective study.

Setting:

Outpatient chemotherapy services.

Participants:

The study included 8 referral cancer centers in the State of São Paulo.

Intervention:

These services were invited to participate in a newly created surveillance program for patients under chemotherapy. Several meetings were convened to share previous experiences on LT-CVC infection surveillance and to define the surveillance method. Once the program was implemented, all bloodstream infection (LT-CVC BSIs), tunnel infection, and exit-site infections associated with LT-CVC were reported. Data from January to May 2021 were analyzed. The median monthly number of chemotherapy sessions per clinic was 925 (IQR, 270–5,855). We used Poisson regression to analyze the association of rates with the characteristics of the services.

Results:

In total, 107 LT-CVC infections were reported, of which 95% were BSIs, mostly associated with totally implantable devices (76%). Infections occurred a median of 4 days after the last catheter manipulation and 116 after the LT-CVC insertion. Also, 102 microorganisms were isolated from LT-CVC BSIs; the most common pathogen was Staphylococcus epidermidis, at 22%. Moreover, 44 infections (44%) fulfilled the criteria for CVC-related LT-CVC BSI and 27 infections (27%) met the criteria for mucosal barrier injury. The 1-year cumulative LT-CVC BSI rate was 1.94 per 1,000 CVC days of use. The rates were higher in public hospitals (IRR, 6.00; P < .001) and in hospitals that already had in place surveillance for LT-CVC infections (IRR, 2.01; P < .01).

Conclusion:

Our study describes an applicable surveillance method for infections in cancer outpatients using LT-CVC.

Published: April 2023

Technological innovations can standardise and minimise reporting errors in dietary assessment. This scoping review aimed to summarise the characteristics of technological tools used to assess children's food intake. The review followed the Joanna Briggs Institute's manual. The main inclusion criterion was studied that assessed the dietary intake of children 0–9 years of age using technology. We also considered articles on validation and calibration of technologies. We retrieved 15 119 studies and 279 articles were read in full, after which we selected 93 works that met the eligibility criteria. Forty-six technologies were identified, 37 % of which had been developed in Europe and 32⋅6 % in North America; 65⋅2 % were self-administered; 27 % were used exclusively at home; 37 % involved web-based software and more than 80 % were in children over 6 years of age. 24HR was the most widely used traditional method in the technologies (56⋅5 %), and 47⋅8 % of the tools were validated. The review summarised helpful information for studies on using existing tools or that intend to develop or validate tools with various innovations. It focused on places with a shortage of such technologies.
Food for our future: the nutritional science behind the sustainable fungal protein – mycoprotein. A symposium review
Authors: Derbyshire Emma J. , Theobald Hannah , Wall Benjamin T , Stephens Francis
Published: April 2023

Mycoprotein is a well-established and sustainably produced, protein-rich, high-fibre, whole food source derived from the fermentation of fungus. The present publication is based on a symposium held during the Nutrition Society Summer Conference 2022 in Sheffield that explored ‘Food for our Future: The Science Behind Sustainable Fungal Proteins’. A growing body of science links mycoprotein consumption with muscle/myofibrillar protein synthesis and improved cardiometabolic (principally lipid) markers. As described at this event, given the accumulating health and sustainability credentials of mycoprotein, there is great scope for fungal-derived mycoprotein to sit more prominently within future, updated food-based dietary guidelines.
Ancient Basidiomycota in an extinct conifer-like tree, Xenoxylon utahense, and a brief survey of fungi in the Upper Jurassic Morrison Formation, USA
Authors: Xie Aowei , Gee Carole T. , Tian Ning
Published: April 2023

Although the well-known Upper Jurassic Morrison Formation has yielded abundant fossil plants for nearly a century, relatively little is known about fossil fungi and their ecological relationships to the Morrison flora. The first mention of fungal decay in fossil wood was briefly made over three decades ago, and since then, a few more reports of fungal decay associated with Morrison plants have been published. However, up to now, detailed data on the fossil fungi themselves have not been given from the Morrison Formation. Here we describe in detail well-preserved fossil mycelia in a silicified log of Xenoxylon utahense Xie et Gee, 2021 from the Upper Jurassic Morrison Formation at Miners Draw, Blue Mountain, near Vernal in northeastern Utah, USA. The fungal hyphae are variable in form, ranging from straight to slightly curved to highly coiled to tubular; they measure ~1.53 μm in diameter and possess clamp connections, septa, and occasional bifurcations. The occurrence of clamp connections typical of living Basidiomycota indicates a taxonomic affinity to this division of fungi. On the basis of the patterns of wood decay in the Xenoxylon log, the fossil fungi are interpreted here as pertaining to saprotrophic, white-rot wood fungi. These fossil mycelia represent a new record of ancient Basidiomycota from the Upper Jurassic Morrison Formation and provide further evidence for plant–fungus interactions in Jurassic terrestrial ecosystems.
New paddlefishes (Acipenseriformes, Polyodontidae) from the Late Cretaceous Tanis Site of the Hell Creek Formation in North Dakota, USA
Authors: Hilton Eric J. , During Melanie A.D. , Grande Lance , Ahlberg Per E.
Published: April 2023

The recently discovered mass mortality of fishes from the Tanis Site in the North Dakota portion of the Late Cretaceous Hell Creek Formation contains many well-preserved, three-dimensional skeletons. Among these are representatives of two acipenseriform families, Acipenseridae (sturgeons) and Polyodontidae (paddlefishes). This paper describes two new monotypic polyodontid genera, expanding our knowledge of polyodontid diversity. The first of the new species described here is †Parapsephurus willybemisi n. gen. n. sp. It is distinguished from all other known species by having a combination of posteriorly elongate parietals, the middle fenestra longitudinalis bordered medially by the parietal and frontal and laterally by the dermopterotic, slender and numerous dorsal caudal fulcra, an elongate hyomandibula that is not hourglass shaped, and gill rakers that are short and widely spaced. The second polyodontid species described here is †Pugiopsephurus inundatus n. gen. n. sp. It is diagnosed by a combination of having stellate bones that are exceptionally poorly developed or absent and having a dermopalatine with a medial expansion and lacking an ectopterygoid process. The two species of paddlefishes described in this paper add to the morphological and taxonomic diversity of Polyodontidae. The presence of these taxa within the Hell Creek Formation hints at substantial diversity of polyodontids at this stage of their evolutionary history.

Drilling predation on Early Jurassic bivalves and behavioral patterns of the presumed gastropod predator—evidence from Pliensbachian soft-bottom deposits of northern Germany
Authors: Karapunar Baran , Werner Winfried , Simonsen Sönke , Bade Manfred , Lücke Markus , Rebbe Thomas , Schubert Siegfried , Rojas Alexis
Published: April 2023

Drilling predation is a common reason for mortality of benthic mollusks but did not become common until the late Mesozoic. The scarcity of drill holes in the early Mesozoic fossil record limits our understanding of the evolution of drilling behavior and its role on shaping early Mesozoic marine communities. Here, we use drilling traces on several bivalve taxa from the Lower Jurassic (Pliensbachian) marine soft-bottom deposits in northern Germany to explore behavioral patterns of the predator (e.g., site selectivity, change in site-selective behavior with age). Although none of the known drilling gastropod groups existed in the Pliensbachian, including the studied localities, the drill-hole morphology suggests that the predator was probably a gastropod. The ecology and identity of the target prey changes from a diverse array of epifaunal to infaunal taxa in older deposits to focus on a single, large, deep infaunal taxon, Gresslya intermedia, in younger deposits, suggesting a potential trend in prey selectivity over time. Spatial point pattern analysis of traces (SPPAT) reveals an aggregated pattern of drill holes on Gresslya, suggesting strong selectivity in drill-hole location. Drilling on a single large infaunal taxon and site selectivity are common patterns also inferred previously from the drilled deep infaunal Eothyasira from the Pliensbachian of southern Germany. In addition to the scarcity of predators, the highly specialized behavior of the early drilling predators, including strong prey selectivity in terms of prey identity and life habit, can partly explain the rarity of the early Mesozoic drill holes.
Phenomenological Laws and Mechanistic Explanations
Authors: Siegel Gabriel , Craver Carl F.
Published: April 2023

In light of recent criticisms by Woodward (2017) and Rescorla (2018), we examine the relationship between mechanistic explanation and phenomenological laws. We disambiguate several uses of the phrase “phenomenological law” and show how a mechanistic theory of explanation sorts them into those that are and are not explanatory. We also distinguish the problem of phenomenological laws from arguments about the explanatory power of purely phenomenal models, showing that Woodward and Rescorla conflate these problems. Finally, we argue that the temptation to pit mechanistic and interventionist theories of explanation against one another occludes important and scientifically relevant research questions.
The Bias Dynamics Model: Correcting for Meta-biases in Therapeutic Prediction
Authors: Erasmus Adrian
Published: April 2023

Inferences from clinical research results to estimates of therapeutic effectiveness suffer due to various biases. I argue that predictions of medical effectiveness are prone to failure because current medical research overlooks the impacts of a particularly detrimental set of biases: meta-biases. Meta-biases are linked to higher-level characteristics of medical research and their effects are only observed when comparing sets of studies that share certain meta-level properties. I offer a model for correcting research results based on meta-research evidence, the bias dynamics model, which employs regularly updated empirical bias coefficients to attenuate estimates of therapeutic effectiveness.
Geophysical sediment properties of a late Pleistocene loess–paleosol sequence, Chenarli, northeastern Iran
Authors: Ghafarpour Amin , Khormali Farhad , Tazikeh Hossein , Kehl Martin , Rolf Christian , Frechen Manfred , Zeeden Christian
Published: April 2023

We present stratigraphic, magnetic, diffuse reflectance spectrophotometric analyses, and chronologic data for the Chenarli loess–paleosol sequence in northeastern Iran. Eight loess units (LU) are identified, described, and constrained in time based on relative stratigraphy and luminescence dating from >130 ± 9.1 ka to ~9.8 ± 0.7 ka. Our data indicate that pedogenic magnetite/maghemite formation gives rise to magnetic enhancement in modern soil and paleosols. The top of LU 7 is demarcated by the well-developed last interglacial soil in which magnetic depletion occurred. We infer that magnetic depletion in this paleosol was produced by reducing conditions in a seasonally waterlogged soil during a warm and wet phase within Marine Isotope Stage (MIS) 5e. Units LU 6 to 1 record several episodes of dust accumulation and soil formation during the last glacial and Holocene. Increased dust accumulation rates occurred during middle-late MIS 3 and lasted into the late MIS 2, with a peak during the last glacial maximum (LU 2). These findings could be applicable to understanding magnetic enhancement/dissolution mechanism in the loess–paleosol sequences in study area. We infer paleoenvironmental changes in northeastern Iran relative to northern Iran, Eurasia, and China.

Published: April 2023

An archaeological excavation conducted on U Kasáren St. in the Prague Castle area (Czech Republic) in 2020 revealed the remains of a medieval settlement consisting of houses of different constructions (pit dwelling, masonry construction), pyrotechnical (possibly metallurgical) features and unspecified pits. The excavation also revealed evidence of fire events and traces of viniculture on the outskirts of the Prague Castle area. Archaeological data allowed only a rough dating of the investigated settlement in the 10th–13th centuries. This paper presents the results of the radiocarbon dating of various materials (animal bones, archaeobotanical samples) from the settlement features and the contribution of the results to the clarification of the chronology of the site.

The Rich Have a Slight Edge: Evidence from Comparative Data on Income-Based Inequality in Policy Congruence
Authors: Persson Mikael , Sundell Anders
Published: April 2023

Several recent studies have found unequal policy responsiveness, meaning that the policy preferences of high-income citizens are better reflected in implemented policies than the policy preferences of low-income citizens. This has been found mainly in a few studies from the US and a small number of single-country studies from Western Europe. However, there is a lack of comparative studies that stake out the terrain across a broader group of countries. We analyze survey data on the policy preferences of about 3,000 policy proposals from thirty European countries over nearly forty years, combined with information on whether each policy proposal was implemented or not. The results from the cross-country data confirm the general pattern from previous studies that policies supported by the rich are more likely to be implemented than those supported by the poor. We also test four explanations commonly found in the literature: whether unequal responsiveness is exacerbated by (a) high economic inequality, (b) the absence of campaign finance regulations, (c) low union density, and (d) low voter turnout.

The experiments reported in this research paper address the effects of replacing ground corn (GC) with full-fat corn germ (FFCG) on nutrient intake and digestibility, nitrogen utilization efficiency, performance, and predicted methane production in dairy cows fed cactus cladodes and sugarcane. We hypothesized that the inclusion of FFCG in the diet would not alter the performance of lactating cows but would reduce the predicted methane production in vivo. Ten multiparous Holstein cows at 90 ± 10 d of lactation and yielding 24.2 ± 3.5 kg milk/d were assigned to dietary treatments consisting of different levels of replacement of GC by FFCG (0; 25; 50; 75 and 100% of diet dry matter) in a replicated 5 × 5 Latin square design with 21-d periods. Methane production was predicted using an automated gas in vitro production system. Except for ether extract intake, which increased, the intake of all nutrients decreased linearly with the replacement of GC by FFCG. The digestibility of dry matter, organic matter and neutral detergent fiber reduced, whereas the digestibility of ether extract increased linearly with FFCG. There were no changes in the digestibility of crude protein. The nitrogen intake and daily excretion in urine and feces decreased, while nitrogen use efficiency increased linearly. There was no significant effect of diets on nitrogen balance or microbial protein synthesis and efficiency. The yield of protein, lactose and total solids in milk showed a quadratic behavior. On the other hand, milk fat yield and energy-corrected milk yield decreased linearly with the replacement of GC by FFCG. No effect on pH or ammonia nitrogen was observed. The production of methane (CH4, g/kg DM) and total CH4 (g/d), and CH4 intensity decreased linearly with the replacement of GC by FFCG. In conclusion, FFCG has been shown to be an effective source of fat to reduce methane production in dairy cows, partially supporting our initial hypothesis. However, as it decreases milk fat production, it is not recommended to replace more than 50% of GC by FFCG for lactating cows fed cactus cladodes and sugarcane.
Control of gastrointestinal helminths in small ruminants to prevent anthelmintic resistance: the Italian experience
Authors: Maurizio Anna , Perrucci Stefania , Tamponi Claudia , Scala Antonio , Cassini Rudi , Rinaldi Laura , Bosco Antonio
Published: April 2023

Helminth infections are ubiquitous in grazing ruminants and cause significant costs due to production losses. Moreover, anthelmintic resistance (AR) in parasites is now widespread throughout Europe and poses a major threat to the sustainability of modern ruminant livestock farming. Epidemiological data on the prevalence and distribution of gastrointestinal nematodes, cestodes and liver- and rumen-flukes in Italian small ruminants are outdated and fragmentary. However, anthelmintics are commonly used to control these infections and often without prior diagnosis. Compared to other European countries, few reports of AR in small ruminants against levamisole, ivermectin and benzimidazoles have been published in Italy, but recent studies suggest that this phenomenon is spreading. Increased and integrated research efforts in developing innovative approaches to control helminth infections and AR are needed and must be tailored to the peculiarities of each context in order to be effectively implemented. This manuscript provides an overview on helminth prevalence and distribution, sustainable treatment strategies and integrated control approaches in small ruminants in Italy. The implementation of targeted treatments and targeted selective treatments is discussed based on different parameters, such as fecal egg count, degree of anaemia (FAMACHA© method), milk production and body condition score. In addition, several Italian studies have also investigated the implementation of alternative strategies such as the use of different natural bioactive compounds or genetic selection for resistance and resilience to helminth infections. These concrete solutions for helminth management in small ruminant farms in the country are reported and discussed, representing a valid example for other Mediterranean countries.
The recontextualisation of Multicultural London English: Stylising the ‘roadman’
Authors: Ilbury Christian
Published: April 2023

Though research on the multiethnolect spoken in London—Multicultural London English (MLE)—has described the social distribution of the variety, the stylistic potentials of MLE remain poorly understood. This article explores the enregisterment and subsequent ‘recontextualisation’ (Bauman & Briggs 1990) of MLE by analysing the linguistic and aesthetic components of a stylistic identity—the ‘roadman’. Specifically, I explore a corpus of TikTok videos to analyse the ways in which linguistic features characteristic of MLE (e.g. pronominal man, discourse-pragmatic styll, fronted /uː/) are co-opted and stylised in parodic performances of the roadman. I demonstrate that these linguistic features co-occur with tropes of personhood (e.g. participation in grime music, overt heterosexuality, a streetwear aesthetic) that are ideologically associated with a particular type of gendered, classed, and racialized identity. Concluding, I reflect on the status of the roadman persona with reference to contemporary patterns of language variation in the UK.

Language immersion effects in the use of tú and usted by L1-French and L1-European Portuguese learners of Spanish
Authors: Sampedro Mella María , Sánchez Gutiérrez Claudia
Published: April 2023

The use of the Spanish pronouns of address tú and usted is an intricate matter for L2 learners due to the many factors that influence their selection at the discourse and interactional level. Although the literature has traditionally focused on the challenges experienced by L1-English learners of L2-Spanish in learning these forms, less is known about speakers whose L1s also present similar (but not identical) pronouns of address. This study thus analyzes the use of tú and usted by L1-French and L1-European Portuguese learners who learn Spanish either in their home countries (i.e., France and Portugal) or in Spain as part of a study-abroad experience. Results indicate that learners in both L1 groups used tú more often while in Spain than in their home country. Additionally, students in immersion started adopting more similar criteria to those of L1-Spanish speakers in determining whether tú or usted would be appropriate in certain contexts.
The Log Product Formula in Quantum K-theory
Authors: CHOU YOU–CHENG , HERR LEO , LEE YUAN–PIN
Published: April 2023

We prove a formula expressing the K-theoretic log Gromov-Witten invariants of a product of log smooth varieties
$V \times W$
in terms of the invariants of V and W. The proof requires introducing log virtual fundamental classes in K-theory and verifying their various functorial properties. We introduce a log version of K-theory and prove the formula there as well.
Crises of Care in China Today
Authors: Steinmüller Hans
Published: April 2023

The introduction to this special section presents an overview of crises of care in China today, specifically as they affect the fields of kinship, health and government. To study care ethnographically, we distinguish between the attentive and active dimensions of care: what people care about, and how they care for others. Acts of care always relate to larger concerns and general values, but they scale up in different ways. The imbalances that emerge are central to the politics of care that our contributors describe. Care as attentive co-growth engages different values, remakes inequality and nourishes political life. The contributors use the same framework of attention, action and politics to investigate crucial issues in Chinese society, including family, health, environment, ritual and animals. In all these fields, care provides a privileged vantage point from which to understand social and moral change in China today.
Father contribution to human resilience
Authors: Feldman Ruth
Published: April 2023

Fathers have been an important source of child endurance and prosperity since the dawn of civilization, promoting adaptation to social rules, defining cultural meaning systems, teaching daily living skills, and providing the material background against which children developed; still, the recent reformulation in the role of the father requires theory-building. Paternal caregiving is rare in mammals, occurring in 3–5% of species, expresses in multiple formats, and involves flexible neurobiological accommodations to ecological conditions and active caregiving. Here, we discuss father contribution to resilience across development. Our model proposes three tenets of resilience – plasticity, sociality, and meaning – and discussion focuses on father-specific contributions to each tenet at different developmental stages; newborn, infant, preschooler, child, and adolescent. Father’s style of high arousal, energetic physicality, guided participation in daily skills, joint adventure, and conflict resolution promotes children’s flexible approach and social competence within intimate bonds and social groups. By expanding children’s interests, sharpening cognitions, tuning affect regulation, encouraging exploration, and accompanying the search for identity, fathers support the sense of meaning, enhancing the human-specific dimension of resilience. We end by highlighting pitfalls to paternal contribution, including absence, abuse, rigidity, expectations, and gender typing, and the need to formulate novel theories to accommodate the “involved dad.”
A transformer-based multi-task framework for joint detection of aggression and hate on social media data

Published: April 2023

Moderators often face a double challenge regarding reducing offensive and harmful content in social media. Despite the need to prevent the free circulation of such content, strict censorship on social media cannot be implemented due to a tricky dilemma – preserving free speech on the Internet while limiting them and how not to overreact. Existing systems do not essentially exploit the correlatedness of hate-offensive content and aggressive posts; instead, they attend to the tasks individually. As a result, the need for cost-effective, sophisticated multi-task systems to effectively detect aggressive and offensive content on social media is highly critical in recent times. This work presents a novel multifaceted transformer-based framework to identify aggressive and hate posts on social media. Through an end-to-end transformer-based multi-task network, our proposed approach addresses the following array of tasks: (a) aggression identification, (b) misogynistic aggression identification, (c) identifying hate-offensive and non-hate-offensive content, (d) identifying hate, profane, and offensive posts, (e) type of offense. We further investigate the role of emotion in improving the system’s overall performance by learning the task of emotion detection jointly with the other tasks. We evaluate our approach on two popular benchmark datasets of aggression and hate speech, covering four languages, and compare the system performance with various state-of-the-art methods. Results indicate that our multi-task system performs significantly well for all the tasks across multiple languages, outperforming several benchmark methods. Moreover, the secondary task of emotion detection substantially improves the system performance for all the tasks, indicating strong correlatedness among the tasks of aggression, hate, and emotion, thus opening avenues for future research.
Human capital and pensions with endogenous fertility and retirement
Authors: Cipriani Giam Pietro , Fioroni Tamara
Published: April 2023

We study an OLG model with child policies and a PAYG pension with endogenous retirement and fertility. The result of the planned economy is compared to the decentralized competitive equilibrium deriving optimal policies. We show that in the presence of a PAYG pension system, the optimal policy mix includes an education subsidy and a subsidy for the supply of labor in old age. Fertility should be taxed or incentivized depending on whether there is full or partial retirement, and on the parameters. We focus on the parameter reflecting the deterioration of human capital and show that a child tax may be required.
Why does Kant Think that Democracy is Necessarily Despotic?
Authors: Caranti Luigi
Published: April 2023

Kant’s criticism of democracy has been traditionally defused with the consideration that Kant’s aversion is not to democracy per se, but to direct democracy. However, what Kant says – ‘to prevent the republican constitution from being confused with the democratic one, as commonly happens’ (ZeF, 8: 351) – appears to count not only against direct democracy, but also against conceptions of democracy closer to the ones we are accustomed to. By offering a new account of what Kant sees as the real problem of democracy (direct or not), the article unpacks a lesson about the limits of democracy that has gone largely unnoticed among political theorists and Kant specialists.
NONREALIZABILITY OF CERTAIN REPRESENTATIONS IN FUSION SYSTEMS
Authors: OLIVER BOB
Published: April 2023

For a finite abelian p-group A and a subgroup
$\Gamma \le \operatorname {\mathrm {Aut}}(A)$
, we say that the pair
$(\Gamma ,A)$
is fusion realizable if there is a saturated fusion system
${\mathcal {F}}$
over a finite p-group
$S\ge A$
such that
$C_S(A)=A$
,
$\operatorname {\mathrm {Aut}}_{{\mathcal {F}}}(A)=\Gamma $
as subgroups of
$\operatorname {\mathrm {Aut}}(A)$
, and . In this paper, we develop tools to show that certain representations are not fusion realizable in this sense. For example, we show, for
$p=2$
or
$3$
and
$\Gamma $
one of the Mathieu groups, that the only
${\mathbb {F}}_p\Gamma $
-modules that are fusion realizable (up to extensions by trivial modules) are the Todd modules and in some cases their duals.
Disjunctive Delimited Control
Authors: VANDENBROUCKE ALEXANDER , SCHRIJVERS TOM
Published: April 2023

Delimited control is a powerful mechanism for programming language extension which has been recently proposed for Prolog (and implemented in SWI-Prolog). By manipulating the control flow of a program from inside the language, it enables the implementation of powerful features, such as tabling, without modifying the internals of the Prolog engine. However, its current formulation is inadequate: it does not capture Prolog’s unique non-deterministic nature which allows multiple ways to satisfy a goal.

This paper fully embraces Prolog’s non-determinism with a novel interface for disjunctive delimited control, which gives the programmer not only control over the sequential (conjunctive) control flow, but also over the non-deterministic control flow. We provide a meta-interpreter that conservatively extends Prolog with delimited control and show that it enables a range of typical Prolog features and extensions, now at the library level: findall, cut, branch-and-bound optimisation, probabilistic programming, …
