A fast strategy to sequentially separate and determine 90Sr, 210Pb and 210Po in water samples using Sr resin
Authors: Martínez J. , de los Cobos M. , Peñalver A. , Aguilar C. , Borrull F. 
Published: December 2021

AbstractThis study presents a rapid and novel sequential separation strategy based on extraction chromatography for determining 90Sr, 210Pb and 210Po in drinking water samples. It involves the use of Sr resin for the separation and then liquid scintillation counting and alpha spectrometry for the determination. The experimental results obtained showed that the proper acidic solution to quantitatively retain the aforementioned radionuclides is 3 M HNO3. The optimum eluents were determined for obtaining quantitative recoveries (70–80%) of 90Sr, 210Pb and 210Po. The method was validated with intercomparison water samples and is satisfactory in terms of minimum detectable activities, which are 50% lower than that established in RD 314/2016.
The QALY is ableist: on the unethical implications of health states worse than dead
Authors: Schneider Paul 
Published: December 2021

Abstract
Introduction
A long-standing criticism of the QALY has been that it would discriminate against people in poor health: extending the lives of individuals with underlying health conditions gains fewer QALYs than extending the lives of ‘more healthy’ individuals. Proponents of the QALY counter that this only reflects the general public’s preferences and constitutes an efficient allocation of resources. A pivotal issue that has thus far been overlooked is that there can also be negative QALYs.

Methods and results
Negative QALYs are assigned to the times spent in any health state that is considered to be worse than dead. In a health economic evaluation, extending the lives of people who live in such states reduces the overall population health; it counts as a loss. The problem with this assessment is that the QALY is not based on the perspectives of individual patients—who usually consider their lives to be well worth living—but it reflects the preferences of the general public. While it may be generally legitimate to use those preferences to inform decisions about the allocation of health care resources, when it comes to states worse than dead, the implications are deeply problematic. In this paper, I discuss the (un)ethical aspects of states worse than dead and demonstrate how their use in economic evaluation leads to a systematic underestimation of the value of life-extending treatments.

Conclusion
States worse than dead should thus no longer be used, and a non-negative value should be placed on all human lives.
Noticing and weighing alternatives in the reflection of regular classroom teaching: Evidence of expertise using mobile eye-tracking

Published: December 2021

Abstract
Instructional videos are widely used to study teachers’ professional vision. A new technological development in video research is mobile eye-tracking (MET). It has the potential to provide fine-grained insights into teachers’ professional vision in action, but has yet been scarcely employed. We addressed this research gap by using MET video feedback to examine how expert and novice teachers differed in their noticing and weighing of alternative teaching strategies. Expert and novice teachers’ lessons were recorded with MET devices. Then, they commented on what they observe while watching their own teaching videos. Using a mixed methods approach, we found that expert and novice teachers did not differ in the number of classroom events they noticed and alternative teaching strategies they mentioned. However, novice teachers were more critical of their own teaching than expert teachers, particularly when they considered alternative teaching strategies. Practical implications for the field of teacher education are discussed.
Robust clustering of functional directional data
Authors: Álvarez-Esteban Pedro C. , García-Escudero Luis A. 
Published: December 2021

AbstractA robust approach for clustering functional directional data is proposed. The proposal adapts “impartial trimming” techniques to this particular framework. Impartial trimming uses the dataset itself to tell us which appears to be the most outlying curves. A feasible algorithm is proposed for its practical implementation justified by some theoretical properties. A “warping” approach is also introduced which allows including controlled time warping in that robust clustering procedure to detect typical “templates”. The proposed methodology is illustrated in a real data analysis problem where it is applied to cluster aircraft trajectories.

Abstract

Purpose
Autoantibodies against apolipoprotein A-1 have been associated with cardiovascular disease, poorer CV outcomes and all-cause mortality in obese individuals. The impact of bariatric surgery (BS) on the presence of circulating anti-apoA-1 IgG antibodies is unknown. This study aimed to determine the effect of bariatric surgery on auto-antibodies titres against Apolipoprotein A-1 (anti-apoA-1 IgG), looking for changes associated with lipid parameters, insulin resistance, inflammatory profile and percentage of excess body mass index loss (%EBMIL).

Materials and Methods
We assessed 55 patients (40 women) before, 6 and 12 months post-operatively. Baseline and post-operative clinical history and measurements of body mass index (BMI), serum cholesterol, triglycerides, high- and low-density lipoprotein cholesterol (HDL-C and LDL-C), apoA-1, highly sensitive C-reactive protein (hsCRP), fasting glucose (FG), glycated haemoglobin (HbA1c) and HOMA-IR were taken at each point. Human anti-apoA-1 IgG were measured by ELISA.

Results
The mean age of participants was 50 years. BS significantly improved BMI, %EBMIL triglycerides, HDL-C, apoA-1, hsCRP, HBA1c, FG and HOMA-IR. Baseline anti-apoA-1 IgG seropositivity was 25% and was associated with lower apoA-1 and higher hsCRP levels. One year after BS, anti-apoA-1 IgG seropositivity decreased to 15% (p = 0.007) and median anti-apoA-1 IgG values decreased from 0.70 (0.56–0.84) to 0.47 (0.37–0.61) AU (p < 0.001). Post-operative anti-apoA-1 IgG levels were significantly associated with a decreased post-surgical %EBMIL at 1 year.

Conclusion
Bariatric surgery results in significant reduction in anti-apoA-1 IgG levels, which may adversely influence weight loss. The exact mechanisms underpinning these results are elusive and require further study before defining any clinical recommendations.

Published: December 2021

AbstractIt is challenging to purify oily wastewater, which affects water-energy-food production. One promising method is membrane-based separation. This paper reviews the current research trend of applying cellulose as a membrane material that mimics one of three typical biostructures: superhydrophobic, underwater superoleophobic, and Janus surfaces. Nature has provided efficient and effective structures through the evolutionary process. This has inspired many researchers to create technologies that mimic nature’s structures or the fabrication process. Lotus leaves, fish scales, and Namib beetles are three representative structures with distinct functional and surface properties: superhydrophobic, underwater superoleophobic, and Janus surfaces. The characteristics of these structures have been widely studied and applied to membrane materials to improve their performance. One attractive membrane material is cellulose, whichhas been studied from the perspective of its biodegradability and sustainability. In this review, the principles, mechanisms, fabrication processes, and membrane performances are summarized and compared. The theory of wettability is also described to build a comprehensive understanding of the concept. Finally, future outlook is discussed to challenge the gap between laboratory and industrial applications.
Exposure of cleaning workers to chemical agents and physical conditions in swimming pools and spas

Published: December 2021

AbstractSwimming pools and spas require a high hygiene level, and therefore constant cleaning. In this study, cleaning workers’ exposure to volatile organic compounds (VOCs), trichloramine (TCA), and particulate matter (PM) in the swimming pools and spas were evaluated. Also, statistical methods were employed to determine what activities affect the exposure to disinfection byproducts (DBPs). The study was conducted in 32 swimming pools and spas. The measurement locations were pool areas, bathrooms, and locker rooms, both during cleaning and opening hours. During the cleaning, the total volatile organic compound (TVOC) concentrations were low, on average 96, 251, and 91 µg/m3 for locker rooms, bathrooms, and pool areas, respectively. Similarly, during the opening hours, the TVOC concentrations were on average 78, 125, and 83 µg/m3, for locker rooms, bathrooms, and pool areas, respectively. This is in line with previous studies investigating cleaning work in other environments. The most prevalent compounds during the cleaning were 2-(2-butoxyethoxy)ethanol (DEGBE), 2-(2-ethoxyethoxy)ethanol (DEGEE), 2-butyl-1-octanol, trichloromethane (chloroform), decamethylcyclopentasiloxane (D5), and carbon tetrachloride. The most prevalent compounds during the opening hours were D5, D-limonene, carbon tetrachloride (bathrooms and pool areas), and trichloromethane (bathrooms and pool areas). The TCA concentrations during the cleaning in the bathrooms and pool areas were on average 60 and 67 µg/m3, respectively, and during the opening hours, 28 and 122 µg/m3, respectively. The use of disinfectants was found to increase the TCA concentration in the bathrooms, while the other cleaning products did not. Even though the TCA concentrations were below the WHO’s guideline and the Finnish occupational exposure limit value of 500 µg/m3, the measured TCA levels were occasionally high enough to pose a risk of irritative symptoms. The PM concentrations were low, both in the real-time monitoring (aerodynamic diameter, Dae ≤ 15 µm) and inhalable dust samples (Dae ≤ 100 µm). Highest measured inhalable dust concentration was 350 µg/m3, well below the Finnish occupational limit value of 5,000 µg/m3 for organic inhalable dust.
“In Our Own Little World”: Invisibility of the Social and Ethical Dimension of Engineering Among Undergraduate Students
Authors: Lim Jae Hoon , Hunt Brittany D. , Findlater Nickcoy , Tkacik Peter T. , Dahlberg Jerry L. 
Published: December 2021

AbstractThis paper explores how undergraduate students understood the social relevance of their engineering course content knowledge and drew (or failed to draw) broader social and ethical implications from that knowledge. Based on a three-year qualitative study in a junior-level engineering class, we found that students had difficulty in acknowledging the social and ethical aspects of engineering as relevant topics in their coursework. Many students considered the immediate technical usability or improved efficiency of technical innovations as the noteworthy social and ethical implications of engineering. Findings suggest that highly-structured engineering programs leave little room for undergraduate students to explore the ethical dimension of engineering content knowledge and interact with other students/programs on campus to expand their “technically-minded” perspective. We discussed the issues of the “culture of disengagement” (Cech, Sci Technol Human Values 39(1):42–72, 2014) fueled by disciplinary elitism, spatial distance, and insulated curriculum prevalent in the current structure of engineering programs. We called for more conscious effort by engineering educators to offer meaningful interdisciplinary engagement opportunities and in-class conversations on ethics that support engineering students' holistic intellectual growth and well-rounded professional ethics.

Published: December 2021

AbstractThe aim of this study was to explore the role of voices as cues to adults of children’s needs for potential caregiving during early childhood. To this purpose, 74 college students listened to pairs of 5-year-old versus 10-year-old children verbalizing neutral-content sentences and indicated which voice was better associated with each of 14 traits, potentially meaningful in interactions between young children and adults. Results indicated that children with immature voices were perceived more positively and as being more helpless than children with mature voices. Children’s voices, regardless of the content of speech, seem to be a powerful source of information about children’s need for caregiving for parents and others during the first six years of life.
Three-Phase Heterojunction NiMo-Based Nano-Needle for Water Splitting at Industrial Alkaline Condition

Published: December 2021

AbstractConstructing heterojunction is an effective strategy to develop high-performance non-precious-metal-based catalysts for electrochemical water splitting (WS). Herein, we design and prepare an N-doped-carbon-encapsulated Ni/MoO2 nano-needle with three-phase heterojunction (Ni/MoO2@CN) for accelerating the WS under industrial alkaline condition. Density functional theory calculations reveal that the electrons are redistributed at the three-phase heterojunction interface, which optimizes the adsorption energy of H- and O-containing intermediates to obtain the best ΔGH* for hydrogen evolution reaction (HER) and decrease the ΔG value of rate-determining step for oxygen evolution reaction (OER), thus enhancing the HER/OER catalytic activity. Electrochemical results confirm that Ni/MoO2@CN exhibits good activity for HER (ƞ-10 = 33 mV, ƞ-1000 = 267 mV) and OER (ƞ10 = 250 mV, ƞ1000 = 420 mV). It shows a low potential of 1.86 V at 1000 mA cm−2 for WS in 6.0 M KOH solution at 60 °C and can steadily operate for 330 h. This good HER/OER performance can be attributed to the three-phase heterojunction with high intrinsic activity and the self-supporting nano-needle with more active sites, faster mass diffusion, and bubbles release. This work provides a unique idea for designing high efficiency catalytic materials for WS.
Fidesz, liberal democracy and the fundamental law in Hungary
Authors: Gomez Gabriel , Leunig Sven 
Published: December 2021

AbstractAfter its landslide victories of 2010, 2014 and 2018, Fidesz has introduced numerous institutional changes in the Hungarian political system. The academic research has emphasized the illiberal and antidemocratic character of these reforms, and the populist ideology of the party has been widely considered as the underlying force behind them. This study analyzes the most important reform that Fidesz has undertaken: the new Fundamental Law, enacted in 2012. We examine whether this change can be regarded as a violation of liberal democratic principles, and, if that is the case, whether it can be linked to the populist character of Fidesz. We found that some of the most criticized dispositions of the newly enacted constitution cannot be regarded as violations of liberal democratic principles, whereas other changes clearly constitute attacks to the foundations of Hungarian democracy, mainly affecting the separation of powers and the civil rights of minorities, These findings are largely consistent with the effects of populist governments on democracy as documented in the literature.

Published: December 2021

AbstractYoung people are the backbone of urban development and an important pillar of social stability. The growth of young floating population in China has given rise to urban land expansion. Understanding the urban life pattern of urban life for young people benefits rational and effective land expansion. In this article, we introduce food delivery data into the process of exploring behavioral patterns of urban youth in Hangzhou, Zhejiang Province, China. The dynamic time warping (DTW) distance-based k-medoids method is applied to explore the main activity areas and activity patterns of the urban youth population. The results indicate that many young people from Hangzhou work in Internet companies, and most of work hotspot areas are observed in high-tech parks. The existence of overtime work is proved. Combined with the housing price data in Hangzhou, it is found that young people consider both housing prices and education environment when choosing where to live. The analysis combined with road network data reflects the planning characteristics of the city, also looks into differences between the actual city functions and the planning map. The proposed methods can provide useful guidance and suggestions for city planning.
Multiple functions of SWI/SNF chromatin remodeling complex in plant-pathogen interactions
Authors: Jian Yunqing , Shim Won-Bo , Ma Zhonghua 
Published: December 2021

AbstractThe SWI/SNF chromatin remodeling complex utilizes the energy of ATP hydrolysis to facilitate chromatin access and plays essential roles in DNA-based events. Studies in animals, plants and fungi have uncovered sophisticated regulatory mechanisms of this complex that govern development and various stress responses. In this review, we summarize the composition of SWI/SNF complex in eukaryotes and discuss multiple functions of the SWI/SNF complex in regulating gene transcription, mRNA splicing, and DNA damage response. Our review further highlights the importance of SWI/SNF complex in regulating plant immunity responses and fungal pathogenesis. Finally, the potentials in exploiting chromatin remodeling for management of crop disease are presented.
More learning, less activism: Narratives of childhood in Australian media representations of the School Strike for Climate
Authors: Alexander Nita , Petray Theresa , McDowall Ailie 
Published: December 2021

AbstractThe School Strike for Climate campaign led to public discussion about children’s political participation. Children are generally excluded from formal political systems, however this campaign challenges mainstream attitudes that children are not sufficiently competent to participate in politics. This paper presents an analysis of Australian mainstream media representations of adult responses to the School Strike for Climate events held in Australia in March 2019. When analysed against theories of childhood, two primary narratives are reflected in what adults said about children’s participation in the campaign. Anticipatory narratives focus on children appropriately developing into adults, and are represented by the notion that strikers should be in school, be punished for missing school, and are ‘just kids’ who should not be listened to. Protectionist narratives seek to shelter children from adult matters, suggesting strikers were brainwashed and raising welfare concerns. Neither of these narratives regard children as citizens capable of political voice, despite these children acting prefiguratively to create a world in which their civic participation is valued. Social movement theories of prefiguration are also explored in this paper, providing a counter argument to suggestions that children have no political agency and should be excluded from activism and discussions regarding climate change.
Casting the atomic canon: (R)evolving nuclear strategy
Authors: Egeland Kjølv , Fraise Thomas , Taha Hebatalla 
Published: December 2021

AbstractLooming decisions on arms control and strategic weapon procurements in a range of nuclear-armed states are set to shape the international security environment for decades to come. In this context, it is crucial to understand the concepts, theories, and debates that condition nuclear policymaking. This review essay dissects the four editions of The Evolution of Nuclear Strategy, the authoritative intellectual history of its subject. Using this widely acclaimed work as a looking glass into the broader field of nuclear security studies, we interrogate the field's underlying assumptions and question the correspondence between theory and practice in the realm of nuclear policy. The study of nuclear strategy, we maintain, remains largely committed to an interpretive approach that invites analysts to search for universal axioms and to abstract strategic arguments from the precise circumstances of their occurrence. While this approach is useful for analysing the locutionary dimension of strategic debates, it risks obscuring the power structures, vested interests, and illocutionary forces shaping nuclear discourse. In the conclusion, we lay out avenues for future scholarship.
PRINCIPAL RADICAL SYSTEMS, LEFSCHETZ PROPERTIES, AND PERFECTION OF SPECHT IDEALS OF TWO-ROWED PARTITIONS
Authors: MCDANIEL CHRIS , WATANABE JUNZO 
Published: December 2021

AbstractWe show that the Specht ideal of a two-rowed partition is perfect over an arbitrary field, provided that the characteristic is either zero or bounded below by the size of the second row of the partition, and we show this lower bound is tight. We also establish perfection and other properties of certain variants of Specht ideals, and find a surprising connection to the weak Lefschetz property. Our results, in particular, give a self-contained proof of Cohen–Macaulayness of certain h-equals sets, a result previously obtained by Etingof–Gorsky–Losev over the complex numbers using rational Cherednik algebras.
Measuring reciprocity: Double sampling, concordance, and network construction
Authors: Ready Elspeth , Power Eleanor A. 
Published: December 2021

AbstractReciprocity—the mutual provisioning of support/goods—is a pervasive feature of social life. Directed networks provide a way to examine the structure of reciprocity in a community. However, measuring social networks involves assumptions about what relationships matter and how to elicit them, which may impact observed reciprocity. In particular, the practice of aggregating multiple sources of data on the same relationship (e.g., “double-sampled” data, where both the “giver” and “receiver” are asked to report on their relationship) may have pronounced impacts on network structure. To investigate these issues, we examine concordance (ties reported by both parties) and reciprocity in a set of directed, double-sampled social support networks. We find low concordance in people’s responses. Taking either the union (including any reported ties) or the intersection (including only concordant ties) of double-sampled relationships results in dramatically higher levels of reciprocity. Using multilevel exponential random graph models of social support networks from 75 villages in India, we show that these changes cannot be fully explained by the increase in the number of ties produced by layer aggregation. Respondents’ tendency to name the same people as both givers and receivers of support plays an important role, but this tendency varies across contexts and relationships type. We argue that no single method should necessarily be seen as the “correct” choice for aggregation of multiple sources of data on a single relationship type. Methods of aggregation should depend on the research question, the context, and the relationship in question.
