GARCHNet: Value-at-Risk Forecasting with GARCH Models Based on Neural Networks
Authors: Buczynski Mateusz , Chlebus Marcin 
Published: May 2023

AbstractThis paper proposes a new GARCH specification that adapts the architecture of a long-term short memory neural network (LSTM). It is shown that classical GARCH models generally give good results in financial modeling, where high volatility can be observed. In particular, their high value is often praised in Value-at-Risk. However, the lack of nonlinear structure in most approaches means that conditional variance is not adequately represented in the model. On the contrary, the recent rapid development of deep learning methods is able to describe any nonlinear relationship in a clear way. We propose GARCHNet, a nonlinear approach to conditional variance that combines LSTM neural networks with maximum likelihood estimators in GARCH. The variance distributions considered in the paper are normal, t and skewed t, but the approach allows extension to other distributions. To evaluate our model, we conducted an empirical study on the logarithmic returns of the WIG 20 (Warsaw Stock Exchange Index), S&P 500 (Standard & Poor’s 500) and FTSE 100 (Financial Times Stock Exchange) indices over four different time periods from 2005 to 2021 with different levels of observed volatility. Our results confirm the validity of the solution, but we provide some directions for its further development.

Published: May 2023

AbstractOne of the biggest difficulties faced by children with Autism Spectrum Disorder during their learning process and general life, is communication and social interaction. In recent years, researchers and practitioners have invested in different approaches to improving aspects of their communication and learning. However, there is still no consolidated approach and the community is still looking for new approaches that can meet this need. Addressing this challenge, in this article we propose a novelty approach (i.e., an Adaptive Immersive Virtual Reality Training System), aiming to enrich social interaction and communication skills for children with Autism Spectrum Disorder. In this adaptive system (called My Lovely Granny’s Farm), the behavior of the virtual trainer changes depending on the mood and actions of the users (i.e., patients/learners). Additionally, we conducted an initial observational study by monitoring the behavior of children with autism in a virtual environment. In the initial study, the system was offered to users with a high degree of interactivity so that they might practice various social situations in a safe and controlled environment. The results demonstrate that the use of the system can allow patients who needed treatment to receive therapy without leaving home. Our approach is the first experience of treating children with autism in Kazakhstan and can contribute to improving the communication and social interaction of children with Autism Spectrum Disorder. We contribute to the community of educational technologies and mental health by providing a system that can improve communication among children with autism and providing insights on how to design this kind of system.
Shifting the ways prospective teachers frame and notice student mathematical thinking: from deficits to strengths
Authors: Scheiner Thorsten 
Published: May 2023

Abstract Noticing the strengths in students’ mathematical thinking is a critical skill that teachers need to develop, but it can be challenging due to the prevalence of deficit-based thinking in mathematics education. To address this challenge, a teacher education course was designed to encourage prospective teachers to engage in critical reflection on their own and others’ framings of students’ thinking and shift their focus towards noticing students’ strengths. The study analyzed written responses from the prospective teachers, collected at the beginning and end of the course, to investigate their framing and noticing of students’ mathematical thinking. The analysis focused on the aspects of students’ thinking that the prospective teachers paid attention to, the stances they took when interpreting students’ thinking, and the instructional moves they proposed in response to their thinking. Furthermore, the study established a spectrum of deficit-based and strength-based framings on students’ mathematical thinking. This spectrum allowed for the identification of each participant’s written noticing responses within a range of possibilities, contributing to a more nuanced understanding of the changes in teachers’ framing and noticing of students’ thinking over time.
Axioms and Postulates as Speech Acts
Authors: Schmidt João Vitor , Venturi Giorgio 
Published: May 2023

AbstractWe analyze axioms and postulates as speech acts. After a brief historical appraisal of the concept of axiom in Euclid, Frege, and Hilbert, we evaluate contemporary axiomatics from a linguistic perspective. Our reading is inspired by Hilbert and is meant to account for the assertive, directive, and declarative components of modern axiomatics. We will do this by describing the constitutive and regulative roles that axioms possess with respect to the linguistic practice of mathematics.
A new salinity index for the invertebrate fauna of Australian inland waters
Authors: Chessman Bruce C. 
Published: May 2023

AbstractAnthropogenic salinisation of inland waters worldwide causes diverse social, economic and ecological impacts, including shifts in the composition of biological communities. I used published data on occurrence of aquatic invertebrate taxa in relation to salinity to develop a novel Invertebrate-Based Salinity Index (IBSI) suitable for purposes such as indicating the ecological impact of anthropogenic salinisation and charting faunal recovery after salinity mitigation. Testing of the index with data independent of those used in its derivation showed a stronger association with salinity than prior Australian salinity indices based on macroinvertebrates. IBSI is applicable to both running and standing inland waters across Australia, and could be extended to other countries. Potential limitations of IBSI and its underlying salinity tolerance values are discussed, and suggestions are made for future index refinement and testing.
Conservation Biogeography of the Dwarf Lemurs (Cheirogaleus) of Madagascar, Investigated via Ecological Niche Modelling
Authors: Hending Daniel , McCabe Grainne , Cotton Sam , Holderied Marc 
Published: May 2023

AbstractEcological niches are the environmental conditions under which an organism can maintain viable populations. A detailed understanding of an organisms’ ecological niche can provide information on its taxonomy and biogeography, and ecological niche modelling allows researchers to investigate how closely-related species are able to coexist. Ecological niche models also enable conservationists to determine species’ habitat requirements, map distributions, and assess threats. We used this approach to investigate the conservation biogeography of the dwarf lemurs (genus Cheirogaleus), a group of cryptic, nocturnal primates endemic to Madagascar. Using climatic and vegetation-related variables, we constructed ecological niche models for three species to investigate niche overlap among taxa. We also constructed maps of the availability of forest habitat, and we assessed anthropogenic risk and protection. Our ecological niche models and background tests indicated that each of the three analysed Cheirogaleus species occupies distinct environmental space. The area of suitable habitat (realized niche) varied interspecifically (28,889–41,934 km2). This also was mirrored by variation in the percentage of each species’ realized niche within protected areas (20,065–25,266 km2) and near anthropogenic features (5,744–16,999 km2). Our results support the 2020 taxonomy of the dwarf lemurs recognised by the IUCN Red List and provides information on their biogeography. Furthermore, our ecological niche models have highlighted that the habitat of some dwarf lemur species, such as C. crossleyi, are more threatened than other species, such as C. medius and C. major, and these species require urgent conservation attention.

Abstract
Autoantibodies (auto-Abs) neutralizing type I interferons (IFNs) are found in the blood of at least 15% of unvaccinated patients with life-threatening COVID-19 pneumonia. We report here the presence of auto-Abs neutralizing type I IFNs in the bronchoalveolar lavage (BAL) of 54 of the 415 unvaccinated patients (13%) with life-threatening COVID-19 pneumonia tested. The 54 individuals with neutralizing auto-Abs in the BAL included 45 (11%) with auto-Abs against IFN-α2, 37 (9%) with auto-Abs against IFN-ω, 54 (13%) with auto-Abs against IFN-α2 and/or ω, and five (1%) with auto-Abs against IFN-β, including three (0.7%) with auto-Abs neutralizing IFN-α2, IFN-ω, and IFN-β, and two (0.5%) with auto-Abs neutralizing IFN-α2 and IFN-β. Auto-Abs against IFN-α2 also neutralize the other 12 subtypes of IFN-α. Paired plasma samples were available for 95 patients. All seven patients with paired samples who had detectable auto-Abs in BAL also had detectable auto-Abs in plasma, and one patient had auto-Abs detectable only in blood. Auto-Abs neutralizing type I IFNs are, therefore, present in the alveolar space of at least 10% of patients with life-threatening COVID-19 pneumonia. These findings suggest that these auto-Abs impair type I IFN immunity in the lower respiratory tract, thereby contributing to hypoxemic COVID-19 pneumonia.
The Expressive Function of Healthcare
Authors: Go Johann 
Published: May 2023

AbstractThis paper aims to square our considered judgements about the moral significance of healthcare with various empirical and conceptual challenges about its role in a theory of justice. I do so by defending the moral significance of healthcare by reference to a central but neglected dimension – healthcare’s expressive function. Over and above its influence on health outcomes and other metrics of justice (such as opportunity or welfare), and despite its relatively limited impact on population health outcomes, healthcare expresses respect for individuals in a distinctive and morally salient way. Grounding the moral significance of healthcare in this way not only highlights an important distinguishing feature of healthcare, but it also makes our support for healthcare immune from several powerful objections against its significance. This conclusion has important implications for theorists of (health) justice and for political philosophers more widely, highlighting the appropriate role of healthcare within public policy and normative theorising about theories of justice.
Structural effects of TiO2 nanoparticles in photocurable ladder-like polysilsesquioxane nanocomposites

Published: May 2023

AbstractLadder-like polysilsesquioxanes (LPSQs) are characterized by a double-stranded siloxane backbone, whose chemical and structural properties depend on both the synthesis parameters and the nature of the organic side-chains. In the case of ladder-like (methacryloxypropyl) polysilsesquioxanes (LPMASQ), polymer matrices can be produced by exploiting the presence of photocurable methacrylate groups. Consequently, they can be used to prepare functional nanocomposites (NCs), either by blending with organic polymers such as polybutadiene or exploiting the inorganic fillers’ dispersion. Since the properties of LPMASQ-based NCs are strongly related to their structure, the structural changes of polymerized LPMASQ were investigated upon addition of low loadings of TiO2 nanoparticles (up to 3 wt%) by solid state nuclear magnetic resonance and X-ray diffraction. The filler addition leads to the reduction of the polymerization capacity of the LPMASQ organic side-chains. Moreover, a different organization of ladder chains has been highlighted, ascribable to the increase in fully condensed linear ladder units at the expenses of folded chains and defective structures. The methodological approach here adopted can be extended to other composite systems and may help to describe the properties at the filler-matrix interface, offering valuable hints for a better design of these materials.

Scalar implicatures with discourse referents: a case study on plurality inferences
Authors: Sudo Yasutada 
Published: May 2023

AbstractThis paper explores the idea that scalar implicatures are computed with respect todiscourse referents. Given the general consensus that a proper account of pronominal anaphora in natural language requires discourse referents separately from the truth-conditional meaning, it is naturally expected that the anaphoric information that discourse referents carry play a role in the computation of scalar implicatures, but the literature has so far mostly exclusively focused on the truth-conditional dimension of meaning. This paper offers a formal theory of scalar implicatures with discourse referents couched in dynamic semantics, and demonstrates its usefulness through a case study on the plurality inferences of plural nouns in English.
A scoping review and a taxonomy of the use of motion-based technology centered on the end user. A special focus on elderly health
Authors: Bossavit Benoit , Fernández-Leiva Antonio J. 
Published: May 2023

AbstractMotion-based technology (MBT) has been applied in the last decades with enormous success in a high number of applications. Its use continues growing and is specially interesting in the health area. Nowadays, its employment is being more and more specialised with respect to the profile of the end user (i.e., child, adolescent/teenager, adult or elderly). This paper first reviews the use of MBT centered in the end user from a global perspective. It also proposes a taxonomy that allows cataloguing the MBT employment directed to the end user. Then, from these results, the paper centers the review on the MBT application aiming to improve the health of elderly. The results highlighted in this paper can help to a better understanding of MBT, especially when it is applied thinking in elderly as the end users.
Prevalence of clinical signs, symptoms and comorbidities at diagnosis of acromegaly: a systematic review in accordance with PRISMA guidelines
Authors: Slagboom Tessa N. A. , van Bunderen Christa C. , De Vries Ralph , Bisschop Peter H. , Drent Madeleine L. 
Published: May 2023

Abstract
Objective
Diagnostic delay is high in acromegaly and leads to increased morbidity and mortality. The aim of this study is to systematically assess the most prevalent clinical signs, symptoms and comorbidities of acromegaly at time of diagnosis.

Design
A literature search (in PubMed, Embase and Web of Science) was performed on November 18, 2021, in collaboration with a medical information specialist.

Methods
Prevalence data on (presenting) clinical signs, symptoms and comorbidities at time of diagnosis were extracted and synthesized as weighted mean prevalence. The risk of bias was assessed for each included study using the Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data.

Results
Risk of bias and heterogeneity was high in the 124 included articles. Clinical signs and symptoms with the highest weighted mean prevalence were: acral enlargement (90%), facial features (65%), oral changes (62%), headache (59%), fatigue/tiredness (53%; including daytime sleepiness: 48%), hyperhidrosis (47%), snoring (46%), skin changes (including oily skin: 37% and thicker skin: 35%), weight gain (36%) and arthralgia (34%). Concerning comorbidities, acromegaly patients more frequently had hypertension, left ventricle hypertrophy, dia/systolic dysfunction, cardiac arrhythmias, (pre)diabetes, dyslipidemia and intestinal polyps- and malignancy than age- and sex matched controls. Noteworthy, cardiovascular comorbidity was lower in more recent studies. Features that most often led to diagnosis of acromegaly were typical physical changes (acral enlargement, facial changes and prognatism), local tumor effects (headache and visual defect), diabetes, thyroid cancer and menstrual disorders.

Conclusion
Acromegaly manifests itself with typical physical changes but also leads to a wide variety of common comorbidities, emphasizing that recognition of a combination of these features is key to establishing the diagnosis.
The Value of Organic plus. Analysing Consumers’ Preference for Additional Ethical Attributes of Organic food Products
Authors: Rizzo Giuseppina , Testa Riccardo , Schifani Giorgio , Migliore Giuseppina 
Published: May 2023

AbstractOrganic Plus attributes strengthen the sustainability of the organic products and differentiate them from the ‘conventionalized’ organic ones. Products with Organic Plus attributes seem appreciated by organic consumers. However, research on consumers’ preference for Organic Plus is still scarce, leaving gaps in the understanding of the consumers’ characteristics of organic products with Plus attributes. In order to enrich the knowledge of consumers’ preference for organic products with Plus attributes, the present study aims to achieve three Objectives: (1) identifying which Plus attributes, among fair prices to local farmers, integration of people with disabilities and eco-friendliness, are most sought after among Italian consumers of organic products (2) measuring, through the willingness to pay elicitation techniques, the level of preference for the various plus attributes; (3) determine which psychological, socio-demographic and contextual factors influence the purchasing choice of organic consumers for the three Plus attributes. Better knowledge of consumers’ preference for organic Plus attributes, as well as the psychological and socio-demographic characteristic can provide useful indications to better-tailored marketing strategies on specific consumers’ profiles.

Authors: Arsad Fadly Syah , Hod Rozita , Ahmad Norfazilah , Baharom Mazni , Ja’afar Mohd Hasni 
Published: May 2023

Abstract
Thermal comfort is linked to our health, well-being, and productivity. The thermal environment is one of the main factors that influence thermal comfort and, consequently, the productivity of occupants inside buildings. Meanwhile, behavioural adaptation is well known to be the most critical contributor to the adaptive thermal comfort model. This systematic review aims to provide evidence regarding indoor thermal comfort temperature and related behavioural adaptation. Studies published between 2010 and 2022 examining indoor thermal comfort temperature and behavioural adaptations were considered. In this review, the indoor thermal comfort temperature ranges from 15.0 to 33.8 °C. The thermal comfort temperature range varied depending on several factors, such as climatic features, ventilation mode, type of buildings, and age of the study population. Elderly and younger children have distinctive thermal acceptability. Clothing adjustment, fan usage, AC usage, and open window were the most common adaptive behaviour performed. Evidence shows that behavioural adaptations were also influenced by climatic features, ventilation mode, type of buildings, and age of the study population. Building designs should incorporate all factors that affect the thermal comfort of the occupants. Awareness of practical behavioural adaptations is crucial to ensure occupants’ optimal thermal comfort.
A Reference System Architecture with Data Sovereignty for Human-Centric Data Ecosystems
Authors: Scheider Simon , Lauf Florian , Möller Frederik , Otto Boris 
Published: May 2023

AbstractSince the European information economy faces insufficient access to and joint utilization of data, data ecosystems increasingly emerge as economical solutions in B2B environments. Contrarily, in B2C ambits, concepts for sharing and monetizing personal data have not yet prevailed, impeding growth and innovation. Their major pitfall is European data protection law that merely ascribes human data subjects a need for data privacy while widely neglecting their economic participatory claims to data. The study reports on a design science research (DSR) approach addressing this gap and proposes an abstract reference system architecture for an ecosystem centered on humans with personal data. In this DSR approach, multiple methods are embedded to iteratively build and evaluate the artifact, i.e., structured literature reviews, design recovery, prototyping, and expert interviews. Managerial contributions embody novel design knowledge about the conceptual development of human-centric B2C data ecosystems, considering their legal, ethical, economic, and technical constraints.

Published: May 2023

AbstractMastering the reaction process of underground pyrolysis is the key to oil shale in-situ conversion project. The progress of the pyrolysis reaction can be analyzed by the information of the kerogen maturity in the reaction formation. However, it is difficult to directly test the kerogen maturity by drilling and coring in in-situ conversion project. And the research on judging the process of underground pyrolysis reaction according to the maturity of oil and gas products has not been carried out in depth. This project intends to take the oil shale of the Nenjiang Formation in the southern Songliao Basin and the pyrolysis oil samples produced by the in-situ conversion project as the research object, and conduct simulation experiments and test analysis. The purpose of this paper is to identify the dynamic evolution characteristics of carbon isotope fractionation during the evolution of oil shale pyrolysis hydrocarbon products, and then establish the response relationship with the process of oil shale organic matter pyrolysis. This study has formed a set of dynamic monitoring methods for the in-situ conversion of oil shale to organic matter pyrolysis reaction process, and laid a theoretical foundation for the efficient, economical and stable operation of oil shale in-situ conversion projects.
