Latent class analysis of IPOs in the Nordics
Authors: Bask Mikael , Nätter Anton Läck
Published: November 2021

We examine how the offer size of initial public offerings (IPOs) and the market return on their issue date are related to the pricing of 314 IPOs issued by firms in Denmark, Finland, Norway and Sweden at the one-day, one-week and four-week horizons using latent class analysis, which is a structural equation methodology. We identify four latent classes at each time horizon, where classes (i)-(ii) include a greater number of IPOs: (i) large-sized and underpriced IPOs; (ii) small-sized and overpriced IPOs; (iii) small-sized and severely underpriced IPOs; and (iv) large-sized IPOs that are overpriced at the one-day horizon but underpriced at the four-week horizon. The market returns are normal in latent classes (i)-(iii) and weak in class (iv). Approximately half of the IPOs in the technology sector are in the latent class with small-sized and overpriced IPOs, and most of the IPOs in the class with small-sized and severely underpriced IPOs are in the healthcare sector. Finally, the underpricing of IPOs is not corrected after one or four weeks of trading. Instead, the mean return and the standard deviation of returns increase with the time horizon.
The relationship between happiness and quality of life: A model for Spanish society
Authors: López-Ruiz Víctor-Raúl , Huete-Alcocer Nuria , Alfaro-Navarro José-Luis , Nevado-Peña Domingo
Published: November 2021

A key goal for society as a whole is the pursuit of well-being, which leads to the happiness of its individual members; as such, it is of critical socioeconomic relevance. In this regard, it is important to study which factors primarily affect the happiness of the population. In principle, these factors are associated with income level and residential and job stability, or more specifically, citizens’ quality of life. This research, which is based on a multidimensional concept of quality of life, uses a regression model to explain the dependence of Spaniards’ happiness on the well-being or quality of life provided by their work, their family situation, their income level and aspects of their place of residence, among other factors. The data were collected through an anonymous survey administered to a representative sample of Spanish citizens. The methodology used approaches the intangible concept of happiness as resulting from different individual and social causes selected from dimensions addressed in the literature, and calculates their effects or importance through regression coefficients. One of the findings is that people with the highest level of well-being or quality of life in the most important dimensions mostly claim to be happy. With respect to gender, it has a significant influence on the dimensions included in the model of citizen happiness and on personal issues. It is also shown that the outbreak of the Covid-19 pandemic negatively influenced the quality of life of Spanish citizens and therefore their happiness.
Pain as the fifth vital sign—A comparison between public and private healthcare systems
Authors: Pozza Daniel Humberto , Azevedo Luís Filipe , Castro Lopes José Manuel
Published: November 2021

Background

The assessment of pain as the fifth vital sign (P5VS) is of paramount importance since it leads to the management of undertreated pain, consequently reducing suffering, readmissions and emergency department visits after hospital discharge.

Objective

To evaluate the implementation of P5VS in public and private hospitals.

Methods

Data analysis on validated questionnaires was sent to all 171 Portuguese hospitals via an official letter.

Results

When compared to private hospitals, public hospitals presented a higher adherence to the process related to the P5VS. It has demonstrated superiority in the charts properly placed to record P5VS, in the number of emergency departments recording P5VS, in the regularity of audits, and in the existence of guidelines and staff training on pain assessment and management.

Conclusion

The standardization of both evaluation and recording of pain intensity constitutes a measure of good clinical practice. Public hospitals demonstrated better commitment to these procedures that should be properly carried out in all health care institutions.
Population attributable risk for multimorbidity among adult women in India: Do smoking tobacco, chewing tobacco and consuming alcohol make a difference?
Authors: Mishra Vivek K. , Srivastava Shobhit , T. Muhammad , Murthy P. V.
Published: November 2021

Background

The present study aims to estimate the prevalence and correlates of multimorbidity among women aged 15–49 years in India. Additionally, the population attributable risk for multi-morbidity in reference to those women who smoke tobacco, chew tobacco, and consume alcohol is estimated.

Methods

The data was derived from the National Family Health Survey which was conducted in 2015–16. The effective sample size for the present paper 699,686 women aged 15–49 years in India. Descriptive statistics along with bivariate analysis were used to do the preliminary analysis. Additionally, binary logistic regression analysis was used to fulfil the objectives.

Results

About 1.6% of women had multimorbidity in India. The prevalence of multimorbidity was high among women from southern region of India. Women who smoke tobacco, chew tobacco and consume alcohol had 87% [AOR: 1.87CI: 1.65, 2.10], 18% [AOR: 1.18; CI: 1.10, 1.26] and 18% [AOR: 1.18; CI: 1.04, 1.33] significantly higher likelihood to suffer from multi-morbidity than their counterparts respectively. Population Attributable Risk for women who smoke tobacco was 1.2% (p<0.001), chew tobacco was 0.2% (p<0.001) and it was 0.2% (p<0.001) among women who consumed alcohol.

Conclusion

The findings indicate the important role of lifestyle and behavioural factors such as smoking and chewing tobacco and consuming alcohol in the prevalence of multimorbidity among adult Indian women. The subgroups identified as at increased risk in the present study can be targeted while making policies and health decisions and appropriate comorbidity management can be implemented.
Gated reverb: Queering the pitch in Trade Queen
Authors: Prout Ryan
Published: November 2021

Director David Wagner says Trade Queen ‘was never intended to be a period film’. However, the suitability of black-and-white 35 mm for the story points to the inflection between markers of analogue and digital registration as one that also codes the boundary between queer and straight experience. This article argues that while Trade Queen is tagged as a film without dialogue, the use of sound design and music in the film is critical to a narrative told aurally as well as visually. Furthermore, it is the use of sound in this film – which ends with vinyl interference – that articulates the tension between analogue and digital, and between heteronormative and queer experience. In punchlines, the synthesized reverb of Ruby Treasure’s score, and in interiors heard from the gated picket fence, we hear as well as see the transitions between public and private selves.
‘Strangely comforted’: The rhetoric of sincerity in Kirsten Lepore’s Hi Stranger
Authors: Kriel-de Klerk Johanet , Rossouw Martin P.
Published: November 2021

This article examines the 2017 viral short film sensation, Kirsten Lepore’s Hi Stranger, with special attention to the weird, even unsettling, potency that her stop-motion animation manages to wield. Why is it that this admittedly ‘creepy’ short ultimately leaves viewers and commenters ‘strangely comforted’? A rhetorical solution to this question is proposed: Hi Stranger’s creepy-yet-comforting appeal derives from the density with which it incorporates an array of rhetorical devices and affective registers – particularly the ‘rhetoric of sincerity’ indicative of a more general ‘metamodern’ sensibility. The intensified sincere rhetoric at work in Hi Stranger moreover has a decidedly reflexive dimension, for this online crowd-puller draws on many devices and registers popular in amateur online videos too: its offers of low-stake, anonymous intimacy and no-strings gifting; its ASMR and ‘cute’ appeal; and its self-professed care and appreciation for the viewer.
Voices from a distance: Sámi short film production in 2020
Authors: Kiejziewicz Agnieszka
Published: November 2021

The sudden outbreak of the COVID-19 pandemic influenced many aspects of film production, which is especially visible in the example of local cinematographies. In this article, I investigate pandemic influence on depicting homeland, memory and locality in Sámi short films. The primary concern in the pre-2000 Sámi short films was the marginalization of Sámi culture, as well as tradition-modernization oppositions. However, in the productions from 2020, a switch into the discourse about the homeland and coping with pandemic in the far north is visible. In this article, I describe productions from 2020, dividing them into three thematic categories: films about the return to the homeland, films focusing on lockdown isolation and films based on genre conventions (such as comedy or horror), used for creating a discursive approach to pandemic. In the proposed article, I analyse Sámi films from the collection of International Sámi Film Institute, produced in Norway, Sweden or Finland.

Legal Status of Collective Subjects of Scientific Work
Authors: Vasiliev Anton , Schopper Dariusz , Pechatnova Yulia
Published: November 2021

The article discusses the study of the legal status of collective subjects of scientific activity. The relevance of the research is predetermined by the importance of the qualitative organization of the work of collective subjects of scientific activity in order to achieve the most effective scientific results. The research methodology includes general methods of scientific research – systemic, logical, historical, as well as special methods, including comparative legal and formal legal. The formal legal method makes it possible to analyze the legal terminology on the research topic above. The method of comparative legal research allows us to compare different points of view and highlight the main problems of legal regulation of collective subjects of scientific law. The research includes three main stages: (1) – terminological analysis of the terminology used by the legislator; (2) – critical analysis of the legal definitions proposed by the legislator and the identification of the problems of legal regulation arising in this connection; (3) – comparison of controversial opinions and determination of ways to improve scientific legislation.
The main problems identified are the uncertainty in the delimitation of the statuses of related collective subjects of scientific work, as well as the mixing of scientific and educational functions of these organizations. As a result of the study, the authors have come to the conclusion that it is necessary to improve legislation aimed at regulating the legal status of scientific organizations and other collective subjects of scientific law.

Published: November 2021

The relevance of the research stipulated by the fact that health is the most important component of human capital, the quality of realization of human labor activity depends on its condition, and, hence, how useful it will be for both his family and the state as a whole. A significant part of the population in Russia does not have access to basic medical care, for many years there has been a decline in the population, and in terms of life expectancy, our country ranks 96th in the world. The aim of this work is to analyze the condition of health capital and health-saving behavior of the population in six border regions of Russia. The empirical basis is the data of the sociological survey conducted in 2020-2021 by the research team of the Altai State University. The main features of the behavior of the residents of the selected regions in preserving their own health revealed. When assessing their health, the respondents most often indicated average and good health. The majority of the population has chronic diseases, among which gastrointestinal diseases, hypertension and spinal diseases are the commonest. Almost half of the respondents do not consume alcohol and do not smoke, regularly see a doctor and do sports in order to stay healthy. The scientific novelty of the study consists in the assessment of the state of health of the population in the border regions, as well as their strategies of health-saving behavior. The practical value of the study consists in the presentation of actual assessments of the health capital of the population of the selected regions, allowing the state to take measures to improve the situation in the regions on this issue.

Colonic ischemia most often presents with abdominal pain and rectal bleeding. Presentation of colonic ischemia as a prominent mass is exceptionally unique and is not often reported. Concern for neoplasm prompted a repeat scope, which revealed the mass had vanished. We present a case of colonic ischemia, which produced a transient colonic mass formed by inflammatory tissue and clots.
Dancing Youth
Authors: Kurfürst Sandra
Published: November 2021

Breaking, popping, locking, waacking, and hip-hop dance are practiced widely in contemporary Vietnam. Considering the dance practices in the larger context of post-socialist transformation, urban restructuring, and changing gender relations, Sandra Kurfürst examines youth's aspirations and desires embodied in dance. Drawing on a rich and diverse range of qualitative data, including interviews, sensory and digital ethnography, she shows how dancers confront social and gender norms while following their passion. As a contribution to area and global studies, the book illuminates the translocal spatialities of hip hop, produced through the circulation of objects and the movement of people.
Moves - Spaces - Places
Authors: Johnson Lisa
Published: November 2021

In the complex and multi-layered process of migration and identity-building, classical migration theories and approaches of transnationalism seem no longer able to grasp how belonging and home are to be found in movement. This ethnography leads the reader into the lives of five Jamaican women in Montreal; their daily practices and experiences, their spaces of communion, their memories and projections for the future. Lisa Johnson sheds light on the mobile biographies and migratory agency of her interlocutors by following the intricate mental and physical trajectories of their deep-rooted yearning to return home.
Repensar la Revolución del Poncho
Authors: Müller Andrea Heidy
Published: November 2021

Este libro ofrece el primer estudio histórico integral sobre la teología de la liberación en Ecuador. Al indagar más allá del llamado »Obispo de los Indios« (L. Proaño), la obra desmitifica las narrativas dominantes sobre el activismo católico postconciliar en los Andes. Este estudio, a partir de la investigación de archivo y la historia oral, explora los entrelazamientos entre el catolicismo progresista latinoamericano, el activismo religioso local, y la formación del movimiento indígena. Repensar la Revolución del Poncho arroja nuevas luces sobre las expresiones locales de un fenómeno transnacional, y sus vínculos con los discursos sobre derechos humanos y la cooperación internacional para el desarrollo.
Ikonische Kohärenz
Authors: Ba Claudia
Published: November 2021

Das performative und materialisierte Erbe des Initiationsritus Kankurang in Senegal und Gambia ist von der UNESCO als »Immaterielles Kulturerbe« unter Schutz gestellt. Claudia Ba untersucht an diesem visuellen Erbe, wie dichotome Verständnisse von Moderne und Tradition in Afrika aufgehoben werden. Mit ihrem Konzept der ikonischen Kohärenz situiert sie raumzeitlich global fluktuierende Bilder visueller Erbekonstruktionen der afrikanischen Gegenwartsgesellschaften. Damit schafft sie einen neuen Modus der Gedächtnisforschung, dessen breites analytisches Potenzial sich an die Sozial- und Kultur- sowie Geschichtswissenschaft, aber auch an Interessierte richtet, die mit global zirkulierenden Bildern arbeiten.
Stadtklanggestaltung
Authors: Kusitzky Thomas
Published: November 2021

Der Klang ist ein elementarer Teil städtischen Lebens und Erlebens. Er ist sinnbehaftet und bedeutsam. In der Stadtgestaltung findet er jedoch, von der Lärmbekämpfung abgesehen, bislang kaum Berücksichtigung. Ausgehend von dieser Feststellung fragt Thomas Kusitzky nach den Konditionen einer bewussten Praxis der Stadtklanggestaltung und zeigt Ansatzpunkte für deren Etablierung auf. Dabei fragt er nicht nur nach der Rolle der Entwerfer*innen und Planer*innen, sondern betrachtet das gesamte Netzwerk der Akteur*innen, die durch ihr aufeinander bezogenes Handeln eine solche Gestaltungspraxis hervorbringen.
Mit Geld spielt man nicht!
Authors: Möll Gerd
Published: November 2021

Es geht um sehr viel Geld. Mehr als 16 Milliarden Euro haben die Menschen in Deutschland im Jahr 2019 beim Glücksspiel verloren. Nach jahrzehntelangem Ringen hat sich die Politik jetzt dazu entschlossen, den Glücksspielmarkt im Internet zu legalisieren - die Suchtexpert*innen sind alarmiert. Vor diesem Hintergrund untersucht Gerd Möll den Glücksspieldiskurs in verschiedenen Landesparlamenten und im Bundestag. Seine Analyse zeigt, dass »Glücksspielsucht« einerseits als medizinischer Sachverhalt präsentiert wird, andererseits aber auf moralischen Wirklichkeitsvorstellungen beruht. Das Problemmuster »Glücksspielsucht« wird dabei für unterschiedliche gesellschaftliche Interessen instrumentalisiert und legitimiert darüber hinaus ein neues Kontrollregime.

Published: November 2021

Scenarios of future development pathways in the Arctic created by groups of experts and stakeholders are an effective way to identify and illustrate possible alternatives and options for this region based on anticipated environmental and socioeconomic changes. Although scenarios that assess development trajectories for the Arctic are becoming increasingly popular, there is a relative lack of regional perspective in foresight exercises devoted to the Russian Arctic. This article presents and discusses development scenarios for the Russian Arctic until 2050 that were built by a diverse group of academics, local officials, Indigenous leaders, and business representatives at a scenario workshop in Naryan-Mar, Russia. The scenarios focus on Russia’s Arctic zone and incorporate future visioning of economic development, international cooperation with the West and China, shipping, human and social capital, and Indigenous peoples’ livelihoods in the context of climate change. We apply a novel circular-axial technique to synthesize and combine the 12 initially created thematic scenarios into four final cross-cutting integrated scenarios that describe alternative futures for the Russian Arctic by 2050: Harmonious Arctic, Self-Reliant Arctic, Resource-Dependent Arctic, and Forgotten Arctic.
Factors Affecting Short-term Solvency of Securities Companies: The Case of Vietnam
Authors: Hai Tran Van
Published: November 2021

A linear regression model supplied in the form of two-dimensional array data was used to investigate the factors affecting the short-term solvency of Vietnamese securities companies. The data is examined with 48 securities companies from 2012 to 2019. The study employed STATA 14 software to evaluate and select regression models, test, and estimate regression models using array data from 235 observations. The findings revealed four characteristics that influence the short-term solvency of securities businesses in Vietnam: the size of the securities company and the quick ratio have a positive impact. In contrast, the debt ratio and the working capital turnover period have a negative effect.
Lifetime Enhancement of Mobile Nodes based Wireless Sensor Networks Using Routing Algorithms
Authors: Alomari Mohammed F. , Alsammak Ihab L. Hussein , Rasool Samer M.
Published: November 2021

Wireless Sensor Nodes are interconnected sensor nodes, that communicate wirelessly to collect surrounding data such as temperature, sound, pressure, motion, or pollutants, and pass the data to the sink where it can be observed are processed. In our sensor nodes is non-rechargeable. Therefore, when a node dies, it causes an interruption in the sensor network as well as creates a huge energy wastage since the problem is faced in real time deployment. A lot of research has been done on WSNs until now. Scientists and researchers have come up with intelligent and efficient routing algorithms to increase the speed and efficiency of the network. One such factor that determines how good a network is, Lifetime. The proposed E-LEACH protocol has better performance in comparison to LEACH and TTDFP in this comparison. The improvement of the efficiency results from choosing the best communication protocol, which decreases packet loss significantly. Therefore, packet loss reduction would eliminate excessive energy-consuming transmissions. The E-LEACH performs about 60% higher than LEACH, while the TTDFP is 20% higher. However, TTDFP effectively transmits its application of a set of rules which take longer to make decisions.
Hepatotoxicity with cholestatic pattern secondary to enoxaparin treatment
Authors: Velasco de Cos Guillermo , Sánchez-Molina Acosta Isabel , Iturralde Ros Marta , Maiztegi Azpitarte Ainhoa , Moyano Martinez Ana
Published: November 2021

Objectives

Treatment with low-molecular-weight heparins is very common in clinical practice. Exceptionally, some patients develop hepatitis within a few days of starting treatment, and rapid discontinuation of the drug is decisive to avoid chronification.

Case presentation

These episodes usually present themselves only with elevated transaminases. We describe the case of a patient who presented a cholestatic pattern, which is very uncommon with this type of drug.

Conclusions

Hepatitis secondary to heparin therapy is an underdiagnosed entity. The laboratory plays a fundamental role in its diagnosis, given that it initially presents itself without a clear clinical profile.
The cognitive-conceptual, planning-organizational, affective-social and linguistic-discursive affordances of translanguaging
Authors: Rajendram Shakina
Published: November 2021

The translanguaging turn in language education offers a new perspective on multilingualism by positing that multilingual learners have one linguistic repertoire rather than two or more autonomous language systems (García, O. & L. Wei. 2014. Translanguaging: Language, bilingualism and education. Palgrave MacMillan). When learners engage in translanguaging, they draw on all the features from their repertoire in a flexible and integrated way (Otheguy, R., O. García & W Reid. 2015. Clarifying translanguaging and deconstructing named languages: A perspective from linguistics. Applied Linguistics Review 6(3). 281–307. DOI:10.1515/applirev-2015-0014). While much of the current literature on language teaching advocates teachers’ use of pedagogical translanguaging, less research has focused on the pedagogical affordances of student-led translanguaging, especially in contexts with dominant monolingual norms. This paper presents the results of a case study exploring the affordances of translanguaging in two multilingual Grade 5 English language classrooms in Malaysia where English-only policies and practices were enforced by the teachers, but where translanguaging was used agentively by learners during their peer-to-peer interactions. The primary data sources for this six-month-long study included 100 30–90 min-long video recordings of 55 learners working together in small groups on various collaborative language learning activities, and member-checking interviews with the learners. The study was grounded in sociocultural theory and translanguaging, and employed a methodology of sociocultural discourse analysis. The results of the analysis revealed that in both classrooms, learners resisted the English-only policies and practices by using translanguaging widely and strategically throughout their collaborative peer-to-peer interactions. The use of translanguaging fulfilled 100 important cognitive-conceptual, planning-organizational, affective-social and linguistic-discursive functions that supported their individual and collective learning. The results of this study provide us with a view of translanguaging as collaborative and agentive, socioculturally situated and culturally responsive, and a resource for learning as well as a process of learning. The study makes recommendations for a language learning pedagogy that creates opportunities for learners to move language policies from the ground up through their collaborative use of translanguaging.

In this work, we consider a fully discrete finite element approximation of the 3D incompressible magnetohydrodynamic system.
The velocity and magnetic field are approximated both by piecewise quadratic finite elements, while the pressure is approximated by piecewise linear finite elements.
The time discretization is based on the Crank–Nicolson scheme for the linear terms in the model and the explicit Adams–Bashforth for the nonlinear terms.
We establish the optimal error estimates of both the approximate velocity and magnetic field in

The intrinsic frame of reference and the Dhivehi ‘FIBO’ system
Authors: Lum Jonathon
Published: November 2021

While geocentric and relative frames of reference have figured prominently in the literature on spatial language and cognition, the intrinsic frame of reference has received less attention, though various subtypes of the intrinsic frame have been proposed. This paper presents a revised classification of the intrinsic frame, distinguishing between three subtypes: a ‘direct’ subtype, an ‘object-centered’ subtype and a ‘figure-anchored’ subtype, with a cross-cutting distinction between ‘function-based’ and ‘shape-based’ systems. In addition, the ‘FIBO’ (front = inner, back = outer) system in Dhivehi is analyzed as an example of a borderline case, with some important features of the intrinsic frame but also some differences, presenting a challenge for existing frame of reference classifications. The rotational properties of these various systems are also considered. The analysis underscores the considerable diversity within intrinsic systems but also points to a closer relationship between intrinsic and extrinsic frames than has previously been appreciated. This may have implications for broader theoretical issues including how frames of reference are acquired, how speech communities come to use different frames and whether patterns of frame use in discourse shape patterns of non-verbal frame use.
Determinants of Japanese Household Saving Behavior in the Low-Interest Rate Environment
Authors: Latsos Sophia , Schnabl Gunther
Published: November 2021

This paper scrutinizes the role of prolonged, expansionary monetary policy on the saving behavior of Japanese households, focusing on the dramatic change of the household savings rate since 1998, from high to low saving. The literature generally attributes this change to the country’s shift from high-growth to low-growth and its demographic change. This paper empirically examines changes in the incentives for saving and the ability to save connected to monetary policy. It finds that monetary policy had a significant impact on Japan’s household saving behavior via the interest rate channel but not the labor income channel. There is also evidence that rising government deficits come along with declining household saving and that rising wealth boosts saving.
Of travels and travails: The role of semantic typology, argument structure constructions, and language contact in semantic change
Authors: Huber Judith
Published: November 2021

This paper is an investigation into the role of argument structure constructions as catalysts or blockers of lexical semantic change. It presents a case study of the divergent semantic development of French travailler ‘work’ and English travel ‘journey’ from their shared earlier meaning ‘labour, toil’. This divergence is shown to not be random: It can be explained as a product of the different intransitive motion constructions (IMCs) and different communicative habits in these two languages. Consequently, the development of travailler ‘journey’ in the Anglo-Norman dialect of French can be understood as the result of contact influence of Middle English. By pointing to similar instances in which verbs meaning ‘labour, toil’ have acquired a polysemous ‘motion’ sense in languages with an IMC that can coerce non-motion verbs into contextual motion readings, the paper argues that this is most probably a regular semantic trajectory in satellite-framing, manner-conflating languages.
The diachronic development of the verbal bracket construction in German
Authors: Smirnova Elena
Published: November 2021

This work-in-progress paper reports the first results of a study dedicated to the investigation of the cognitive status of the sentence bracket construction in German. The project aims at a comprehensive corpus analysis of diachronic data from the Early New High German period (ENHG, 1350–1650). The study focuses on the syntactic structures of German main clauses and is guided by two general research questions. First, on the conceptual level, it addresses the question of whether the sentence bracket construction can be considered a construction in its own right. Second, the paper deals with the issue of the diachronic source(s) of the sentence bracket construction. Based on ENHG corpus data, it examines the role of grammaticalization of verbal auxiliaries in the development of the bracket construction. On a more general level, the objective of the paper is to encourage the discussion on the cognitive status of syntactic phenomena which often escape a straightforward modelling in cognitive and constructionist terms, as they do not seem to bear a particular dedicated semantic and/or functional value.
The problem of universalism in (diachronic) cognitive linguistics
Authors: Bergs Alexander
Published: November 2021

Modern cognitive science and cognitive linguistics are characterized by a universalist perspective, i.e., they are investigating features and principles of cognition which can be found in all members of the human species. This in turn means that they should not only be relevant for present-day cognizers and language users, but also historically. This theoretical, programmatic paper first explores this notion of universalism in cognitive science and cognitive linguistics and suggests that the notion of cognitive universalism should be supplemented by perspectives from cognitive sociology and social cognition. These offer a middle ground in that they look at cognition as it is socially and culturally grounded, and hence inter-individual, but yet not universal. A final section on diachronic cognitive linguistics shows that in language history all three perspectives, individual, social, and universal, can have their place, and that one line of future research should explore this new perspective of social cognition in language history in order to arrive at a fuller picture of historical language users and their cognition.
On the splitting type of holomorphic vector bundles induced from regular systems of differential equation
Authors: Giorgadze Grigori , Gulagashvili Gega
Published: November 2021

We calculate the splitting type of holomorphic vector bundles on the Riemann sphere induced by a Fuchsian system of differential equations. Using this technique, we indicate the relationship between Hölder continuous matrix functions and a moduli space of vector bundles on the Riemann sphere. For second order systems with three singular points we give a complete characterization of the corresponding vector bundles by the invariants of Fuchsian system.

Published: November 2021

Collecting data on households and individuals since 1999, the Swiss Household Panel (SHP) is an ongoing, unique, large-scale, nationally representative, longitudinal study in Switzerland (N = 9828 households and N = 15,882 persons interviewed in 2020). The SHP aims to provide both continuity and innovation in measurement and data collection. Examples of innovation are the combination of retrospective and prospective longitudinal data, the combination of survey modes notably in refreshment samples and additional studies oversampling specific population groups. This article provides an overview of the SHP – focusing on the survey’s key design features, content, data collection and adjustments, possibilities for cross-national comparisons, data use and accomplishments.
Construction design based on particle group optimization algorithm
Authors: Xia Ying , Ikbal Mohammad Asif , Shah Mohd Asif
Published: November 2021

The machines exhibit an intelligence which is artificial intelligence (AI), and it is the design of intelligent agents. A system is represented by an intelligent agent who perceives its environment and the success rate is maximized by taking the action. The AI research is highly specialized and there are two subfields and each communication fails often. The popular AI approaches include the traditional symbolic AI and computational intelligence. In order to optimize the seismic design of the reinforced concrete pier structure, the particle swarm optimization (PSO) algorithm and the reaction spectrum analysis method are combined; they establish a regular bridge of the design variable with cross-sectional characteristics and reinforcement ratios, with the target function. The seismic optimization design framework of the pier is transformed into a multi-objective optimization problem. Calculations show that the method can quickly obtain the optimal design parameters that meet multi-objective requirements. The improved PSO main program and the calling push-over program run time are 4.32 and 1347.56 s, respectively; the push-over program running time is 99.68% of the run time of the total program. Optimization of the seismic performance of the rear bridge pier is significantly improved and is more in line with the design method; the design method proposed in this article is more practical.

Objectives

Maternal and fetal complications can occur in pregnant kidney transplant recipients. Since these are high-risk pregnancies, they require a multidisciplinary follow-up to prematurely detect adverse events. Identifying factors that would affect fetal, maternal and graft outcomes is essential to further stratify the risk of pregnant kidney transplant recipients.

Methods

All pregnancies in kidney transplant recipients followed in a single center for 30 years were included. Data included previous transplant information and blood and urine tests performed before pregnancy. Impact of graft function on fetal, maternal and graft outcomes was evaluated.

Results

There were 41 pregnancies among 34 patients. Mean gestational age of 35 ± 3 weeks. Caesarean section was performed in 69.4% of patients. Five pregnancies were unsuccessful (12.2%). Four patients suffered an acute graft dysfunction (9.8%) and 12 (29.3%) had a serious maternal hypertensive disorder (preeclampsia, eclampsia or HELLP syndrome). Graft function before pregnancy showed significant correlation with adverse outcomes.

Conclusions

A proteinuria >669 mg/g, serum creatinine >1.75 mg/dL and glomerular filtration rate <36.2 mL/min/1.73 m2 before pregnancy were correlated to graft dysfunction during pregnancy. Similar values of proteinuria were also associated with a risk of maternal hypertensive disorders and pregnancy failure. Therefore, in patients with proteinuria and graft dysfunction, follow-up should be stricter to quickly detect complications.

Background

The increasing use of new technologies by pregnant women inevitably exposes them to the risks of the electromagnetic fields (EMFs). According to the World Health Organization, EMFs are the major sources of pollutants which harm human health. This study was aimed to evaluate the effects of EMF exposure on abortion.

Methods

Web of Science, Cochrane Library, MEDLINE, PubMed, EMBASE, Scopus, and Google Scholar were searched until 2021. Pooled odds ratio (OR) with 95% confidence interval (CI) was estimated using a random-effects model. Heterogeneity was explored using Cochran’s Q test and I
2 index. A meta-regression method was employed to investigate the factors affecting heterogeneity between the studies. The Newcastle-Ottawa scale was used to assess the credibility of the studies.

Results

Eligible studies (N = 17) were analyzed with a total of 57,693 participants. The mean maternal age (95% CI) was 31.06 years (27.32–34.80). Based on meta-analysis results, the pooled estimate for OR of EMF with its effects was 1.27 (95% CI: 1.10–1.46). According to the results of meta-regression, sample size had a significant effect on heterogeneity between studies (p: 0.030), but mother’s age and publication year had no significant effect on heterogeneity (p-value of bothwere >0.05). No publication bias was observed.

Conclusion

Exposure to EMFs above 50 Hz or 16 mG is associated with 1.27× increased risk of abortion. It may be prudent to advise women against this potentially important environmental hazard. Indeed, pregnant women should receive tailored counselling.

Published: November 2021

We have grown arrays of silver nanowires in pores of anodic alumina membranes (metamaterials with hyperbolic dispersion at λ ≥ 615 nm), spin coated them with the dye-doped polymer (HITC:PMMA), and studied the rates of radiative and nonradiative relaxation as well as the concentration quenching (Förster energy transfer to acceptors). The results were compared to those obtained on top of planar Ag films and glass (control samples). The strong spatial inhomogeneity of emission kinetics recorded in different spots across the sample and strong inhibition of the concentration quenching in arrays of Ag nanowires are among the most significant findings of this study.
Establishing exhaustive metasurface robustness against fabrication uncertainties through deep learning

Published: November 2021

Photonic engineered materials have benefitted in recent years from exciting developments in computational electromagnetics and inverse-design tools. However, a commonly encountered issue is that highly performant and structurally complex functional materials found through inverse-design can lose significant performance upon being fabricated. This work introduces a method using deep learning (DL) to exhaustively analyze how structural issues affect the robustness of metasurface supercells, and we show how systems can be designed to guarantee significantly better performance. Moreover, we show that an exhaustive study of structural error is required to make strong guarantees about the performance of engineered materials. The introduction of DL into the inverse-design process makes this problem tractable, enabling optimization runtimes to be measurable in days rather than months and allowing designers to establish exhaustive metasurface robustness guarantees.

The optical properties of thin-film light emitting diodes (LEDs) are strongly dependent on their structures due to light interference inside the devices. However, the complexity of the design space grows exponentially with the number of design parameters, making it challenging to optimize the optical properties of multilayer LEDs with rigorous electromagnetic simulations. In this work, we demonstrate an artificial neural network that can predict the light extraction efficiency of an organic LED structure in 30 ms, which is ∼103 times faster than the rigorous simulation in a single-treaded execution with root-mean-squared error of 1.86 × 10−3. The effective inference time per structure is brought down to ∼0.6 μs with unaltered error rate with parallelization. We also show that our neural networks can efficiently solve the inverse problem – finding a device design that exhibits the desired light extraction spectrum – within the similar time scale. We investigate the one-to-many mapping issue of the inverse problem and find that the degeneracy can be lifted by incorporating additional emission spectra at different observing angles. Furthermore, the forward neural network is combined with a conventional genetic algorithm to address additional large-scale optimization problems including maximization of light extraction efficiency and minimization of angle dependent color shift. Our approach establishes a platform for tackling computation-heavy optimization tasks with one-time computational cost.
The influence of pigment modulus on failure resistance of paper barrier coatings
Authors: Zhu Yaping , Bousfield Douglas , Gramlich William
Published: November 2021

Pigments are often used in water borne barrier coatings but tend to make the coatings prone to failure. The pigment properties effects on this issue is lacking in literature. In this work, coatings that used pigments with different moduli but with similar size and aspect ratio were characterized in terms of water vapor resistance before and after folding. Coatings with talc had better water vapor resistance than coatings with similar sized kaolin. Talc also limited the degradation of barrier properties when folded. Coatings with metalized poly(ethylene terephthalate) (PET) flakes had better failure resistance than coatings with similarly sized rigid mica. Both results are likely caused by the ability of the low modulus pigment to deform and allow for strain to occur in the pigment as well as the latex phase. Styrene-butadiene (SB) and natural rubber (NR) latex coatings had a better failure resistance than styrene-acrylate (SA) latex, which is likely due to their low glass transition temperatures and high strain-to-failure values. However, coatings with high amounts of SB or NR latex may lead to blocking issues in production. Adding kaolin into SA and SB latex mixtures resulted in improved water vapor barrier property and failure resistance.
Preliminary Evaluation of the Terrestrial Laser Scanning Survey of the Subterranean Structures at Hagia Sophia

Published: November 2021

This article presents the preliminary evaluation of the first terrestrial laser scan survey on the subterranean structures of Hagia Sophia, which was built in the Late Antique Era in Istanbul. The project which was carried out in 2020, aimed to study the underground network of Hagia Sophia which consists of ventilation channels, wells, and other spatial units of various sizes, serving various functions (e.g. a passage, hypogeum, and cellar). This project allowed for a visualization of units that have a total length of approximately 936 m. According to our observations, this infrastructure provided water supply, drainage, and air circulation. The cloud point data derived from the scanning provided us with a plan overlapping with the ground floor, and multiple cross-sections which present the relationship of the different layers with each other. To this end, the survey helps understand the different underground layers, as well as their relations with the superstructures. These relations enabled us to discuss on the atriums of the Theodosian Hagia Sophia and Justinian’s Hagia Sophia. Finally, we could determine the points where the debris and mud has blocked or restricted air circulation in the channels.
