COVID-19, mathematics education, and the evaluation of expert knowledge
Authors: Kollosche David , Meyerhöfer Wolfram 
Published: August 2021

AbstractMaturity and citizenship in a democracy require that laypersons are able to critically evaluate experts’ use of mathematics. Learning to critically reflect on the use of mathematics, including the acquisition of the mathematical knowledge and skills required to that end, has been repeatedly postulated as an indispensable goal of compulsory education in mathematics. However, it remained unclear in how far such reflection is possible, even for the well-educated layperson in mathematics. We use different discussions in German mass media on the pandemic policy in the SARS-CoV-2 crisis in 2020 as examples with far-reaching individual and social consequences. The selected discussions build heavily on mathematical concepts such as mortality rates, casualty numbers, reproduction numbers, and exponential growth. We identify the concepts and discuss how far they can be understood by laypersons. On the one hand, we found that some mathematical models are inappropriate, which can also be determined by laypersons. On the other hand, we found uses of mathematics where ideal concepts are intermingled with complex statistical concepts. While only the ideal concepts can be understood by laypersons, only the statistical concepts lead to actual data. The identification of both types of concepts leads to a situation where the use of mathematics evades social control and opens spaces for misconceptions and manipulation. We conclude that the evaluation of experts’ use of mathematics by laypersons is not possible in all relevant cases, and we discuss possible implications of this result.

AbstractSince its identification in 2003, grapevine Pinot gris virus (GPGV, Trichovirus) has now been detected in most grape-growing countries. So far, little is known about the epidemiology of this newly emerging virus. In this work, we used datamining as a tool to monitor in-silico the sanitary status of three vineyards in Italy. All data used in the study were recovered from a work that was already published and for which data were publicly available as SRA (Sequence Read Archive, NCBI) files. While incomplete, knowledge gathered from this work was still important, with evidence of differential accumulation of the virus in grapevine according to year, location, and variety-rootstock association. Additional data regarding GPGV genetic diversity were collected. Some advantages and pitfalls of datamining are discussed.
Demands and design principles of a “heterodox” didactics for promoting critical thinking in higher education
Authors: Ostendorf Annette , Thoma Michael 
Published: August 2021

AbstractFollowing on from the already wide-ranging academic discussion about fostering critical thinking in students as an important component of a university’s educational mission, this paper takes a particular look at didactic principles for fostering this critical thinking. We begin with a reception of Abrami et al.’s (2015) comprehensive meta-study of higher education interventions that are successful in promoting critical thinking. It becomes apparent that an understanding of criticism, which we refer to as “conventional” has been used throughout. However, there are alternative designs of an understanding of critique and critical thinking. We therefore subsequently explain an understanding of critique that is oriented toward poststructuralist thought and is referred to as “deconstructive”. Didactic principles that can be called “heterodox” are presented, which are suitable to promote a critical thinking ability in the light of the poststructuralist-inspired concept of critique. These principles are not only theoretically negotiated, but also vividly explained by means of a concrete intervention in university teaching. The article concludes with reflections on the connection of “conventional” and “heterodox” didactic principles for the promotion of critical thinking and gives impulses for the further development of university teaching-learning arrangements.
Variational Bayesian representation learning for grocery recommendation
Authors: Meng Zaiqiao , McCreadie Richard , Macdonald Craig , Ounis Iadh 
Published: August 2021

AbstractRepresentation learning has been widely applied in real-world recommendation systems to capture the features of both users and items. Existing grocery recommendation methods only represent each user and item by single deterministic points in a low-dimensional continuous space, which limit the expressive ability of their embeddings, resulting in recommendation performance bottlenecks. In addition, existing representation learning methods for grocery recommendation only consider the items (products) as independent entities, neglecting their other valuable side information, such as the textual descriptions and the categorical data of items. In this paper, we propose the Variational Bayesian Context-Aware Representation (VBCAR) model for grocery recommendation. VBCAR is a novel variational Bayesian model that learns distributional representations of users and items by leveraging basket context information from historical interactions. Our VBCAR model is also extendable to leverage side information by encoding contextual features into representations based on the inference encoder. We conduct extensive experiments on three real-world grocery datasets to assess the effectiveness of our model as well as the impact of different construction strategies for item side information. Our results show that our VBCAR model outperforms the current state-of-the-art grocery recommendation models while integrating item side information (especially the categorical features with the textual information of items) results in further significant performance gains. Furthermore, we demonstrate through analysis that our model is able to effectively encode similarities between product types, which we argue is the primary reason for the observed effectiveness gains.

AbstractInternalising problems are common within Autism Spectrum Disorder (ASD); early intervention to support those with emerging signs may be warranted. One promising signal lies in how individual differences in temperament are shaped by parenting. Our longitudinal study of infants with and without an older sibling with ASD investigated how parenting associates with infant behavioural inhibition (8–14 months) and later effortful control (24 months) in relation to 3-year internalising symptoms. Mediation analyses suggest nondirective parenting (8 months) was related to fewer internalising problems through an increase in effortful control. Parenting did not moderate the stable predictive relation of behavioural inhibition on later internalising. We discuss the potential for parenting to strengthen protective factors against internalising in infants from an ASD-enriched cohort.

Published: August 2021

AbstractThe COVID-19 pandemic has created unprecedented challenges and disruptions for autistic individuals receiving specialized treatment services. This caregiver-report survey study (n = 339) explored predictors of satisfaction with autism services during COVID-19 to improve perceived support for these families. Specifically, we investigated whether service delivery medium (telehealth vs. in person), child’s emotional functioning, and caregiver stress would predict satisfaction with the most highly utilized services. Satisfaction ratings for ABA/behavioral, speech/language, and occupational therapy were lower when delivered via telehealth as compared to in person. Caregivers who reported higher emotional dysregulation in their children were less satisfied with behavioral therapy services. These results provide a critical caregiver-informed perspective on factors influencing satisfaction with specialized autism services during COVID-19.

Published: August 2021

AbstractTo understand the perspectives and needs of autistic children and their families in the context of an emergency, 109 parents and 56 autistic children (5.75–18 years) from Canada completed an online survey about needs, barriers and facilitators to coping with the pandemic. Parents’ concerns about their child’s development and difficulties managing their child’s behaviors before and during pandemic were significantly associated. Parents identified maintaining social relationships and implementing appropriate interventions to their child’s characteristics as facilitators during the pandemic. Both children and parents identified lack of socialization as a main difficulty. Among children, 92.9% associated electronic devices with their well-being. This study highlighted the need to consider the child’s autistic characteristics and interests to implement emergency accommodations and services.

Published: August 2021

AbstractAsthma outcomes remain suboptimal, despite effective pharmacotherapy. Psychological dysfunction (such as anxiety) is common, and associated with poorer outcomes. We evaluated a digital mindfulness programme as an intervention to improve asthma-related quality of life for primary care patients, in a prospectively registered randomized-controlled feasibility study. We offered ‘Headspace’, a widely-used digital mindfulness intervention, to adults with asthma through 16 UK GP practices. Participants were randomized on a 2:1 basis to the mindfulness intervention, or waitlist control. Participants completed questionnaires (including asthma symptom control, asthma-related quality of life, anxiety, depression) at baseline, 6-week and 3-month follow-up. 116 participants completed primary outcomes at 3-month follow-up: intervention 73 (79%), control 43 (84%). Compared to baseline, the intervention group but not the control group reported significantly improved asthma-related quality of life, with a between-group difference favoring the intervention group that was not significant (Mean difference = 0.15, 95%CI − 0.13 to 0.42). Intervention use varied (ranging from 0 to 192 times) but was generally high. Digital mindfulness interventions are feasible and acceptable adjunct treatments for mild and moderate asthma to target quality of life. Further research should adapt ‘generic’ mindfulness-based stress-reduction to maximize effectiveness for asthma, and validate our findings in a fully-powered randomized controlled trial.Trial registration Prospectively registered: ISRCTN52212323.
Strengthening the satisfaction loyalty link: the role of relational switching costs
Authors: Evanschitzky Heiner , Stan Valentina , Nagengast Liane 
Published: August 2021

AbstractThe extant retail research has placed much emphasis on understanding customer switching and the concept of switching costs (SCs). However, the empirical evidence is inconclusive with respect to the moderating role of SCs in general and relational switching costs (RSCs) in particular. Therefore, this research focuses on the moderating role played by SCs on the satisfaction-loyalty link. Specifically, our study attempts to clarify the nonlinear moderating effect of RSCs. Furthermore, we investigate RSCs in greater depth, considering their two dimensions, brand relationship loss costs (BRLCs), and personal relationship loss costs (PRLCs). We find that there is an optimal level of BRLC whereas increasing PRLCs decreases the impact of satisfaction on loyalty in a linear manner, calling for a more nuanced assessment of this type of SC in future studies. Our findings contribute to a deeper understanding of the effectiveness of SCs as a retention strategy.
The Subversion of Francoist Rhetoric in Blas de Otero’s Pido la paz y la palabra
Authors: O’Donoghue Samuel 
Published: August 2021

AbstractThis article explores the ways in which socially and politically engaged poetry challenged the Franco regime in mid-twentieth-century Spain. A close reading of the work of Blas de Otero reveals how this poet crafts a discordant voice by alluding to, mimicking, and subverting the very myths and rhetoric of Franco’s regime. Working against the strictures of state censorship, Blas de Otero usurps the linguistic idiosyncrasies and thematic tropes characteristic of Francoist discourse and redeploys them in a distorted form in his poetry of protest. This article shows ultimately how poets such as Otero were able to engage with the social realities the regime was anxious to conceal by contesting one of the most conspicuous manifestations of the regime’s power—its monopoly of public discourse—and how such writers were able thereby to contribute to the erosion of the regime’s authority and to its discredit among cultivated readers in 1950s Spain.
Multi-scale approach for different type of drought in temperate climatic conditions
Authors: Minea Ionuţ , Iosub Marina , Boicu Daniel 
Published: August 2021

AbstractDrought with its occurrence and manifestations at all levels of the natural components, yields both direct and indirect negative effects, on the ecological systems, water resources, social, as well as economic aspects of life. Therefore, any analysis that concerns this phenomenon, must be carried out at a multi-scalar level, addressing all manifestation levels (meteorological, hydrological, and hydrogeological drought). Standardized evaluation indices (for precipitation-SPI, evaporation-, -SPEI, streamflow-SDI and groundwater-SGI) have been used to analyze the evolution of the drought phenomena in Eastern Romania, for 1, 3, 6 and 12 months’ time-scales, applied to seven groundwater bodies. The results of the analysis complement the observations concerning the evolution of meteorological drought (using SPI and SPEI) in the East European region, by highlighting the drought sequences of the last two decades of the last century. Those are accompanied by the meteorological drought sequences which occurred on extensive areas, starting from 2007, until present, with direct effects in river discharge and increases in groundwater level depths. The Bravais–Pearson correlation coefficient shows a close connection between meteorological and hydrological drought (r ~ 0.45 to 0.68) and between hydrological and groundwater drought (r ~ 0.42 to 0.74) for wells with piezometric level under 5 m depth. In the larger context of climate scenarios which envision an increase in air temperature, and a decrease in the atmospheric hydrological input, the increase in the drought frequency is obvious, with direct effects on all-natural components that are dependent on the hydrological resources.
Slurs under quotation
Authors: Rinner Stefan , Hieke Alexander 
Published: August 2021

AbstractAgainst content theories of slurs, according to which slurs have some kind of derogatory content, Anderson and Lepore have objected that they cannot explain that even slurs under quotation can cause offense. If slurs had some kind of derogatory content, the argument goes, quotation would render this content inert and, thus, quoted slurs should not be offensive. Following this, Anderson and Lepore propose that slurs are offensive because they are prohibited words. In this paper, we will show that, pace Anderson and Lepore, content theories of slurs do provide an explanation of the fact that quoted slurs can cause offense: even under quotation, the explanation goes, the derogatory content of a slur can still be psychologically efficacious. We will go one step further by pointing out that offensiveness is not the only function of slurs, but that slurs can also be used to create and reinforce negative attitudes towards the target group. While content theories can easily explain this by referring to some kind of derogatory content, Anderson and Lepore’s prohibitionism will lack a satisfactory explanation of this second function of slurs. Concluding, we will argue that, unlike uses of slurs, uses of quoted slurs normally do not derogate the target group. This will again speak in favor of content theories. Accordingly, uses of quoted slurs are not derogatory because quotation renders the derogatory content inert. Hence, rather than speaking against content theories, quoted slurs speak in their favor.
The influence of panel effects and inertia on travel cost elasticities for car use and public transport

Published: August 2021

AbstractStudies on the impact of changes in travel costs on car and public transport use are typically based on cross-sectional travel survey data or time series analysis and do not capture intrapersonal variation in travel patterns, which can result in biased cost elasticities. This paper examines the influence of panel effects and inertia in travel behaviour on travel cost sensitiveness, based on four waves of the Mobility Panel for the Netherlands (comprising around 90,000 trips). This paper analyses the monetary costs of travel. Panel effects reflect (within wave) intrapersonal variations in mode choice, based on three-day trip diary data available for each wave. The impact of intrapersonal variation on cost sensitiveness is shown by comparing mode choice models with panel effects (mixed logit mode choice models with error components) and without panel effects (multinomial logit models). Inertia represents variability in mode choice between waves, measured as the effect of mode choice decisions made in a previous wave on the decisions made in the current wave. Additionally, all mode choice models include socio-economic and spatial variables but also mode preferences and life events. The effect of inertia on travel cost elasticities is measured by estimating mixed logit mode choice models with and without inertia effects. The main conclusion is that the inclusion of intrapersonal effects tends to increase cost sensitiveness whereas the inclusion of inertia effects decreases travel cost sensitiveness for car and public transport modes. Car users are identified as inert travellers, whereas public transport users show a lower tendency to maintain their usual mode choice. This paper reveals the inertia effects over four waves of repeated respondent’s data repeated yearly.
Capital requirements, risk-taking and welfare in a growing economy
Authors: Agénor Pierre-Richard , Silva Luiz A. Pereira da 
Published: August 2021

AbstractThe effects of capital requirements on risk-taking and welfare are studied in an overlapping generations model of endogenous growth with banking, limited liability, and government guarantees. Capital producers face a choice between a safe technology and a risky, more productive but socially inefficient, technology. Bank risk-taking is endogenous. As a result of a skin in the game effect—motivated either as an aggregate externality, or as the outcome of the optimal choice of monitoring effort by individual banks—default risk is inversely related to the capital adequacy ratio. Numerical simulations show that in an equilibrium where banks extend both safe and risky loans, the skin in the game effect must be sufficiently strong for a welfare-maximizing regulatory policy to exist. These results remain qualitatively similar with endogenous monitoring costs and a strong effect of monitoring on entrepreneurial moral hazard. However, numerical experiments also suggest that the optimal capital adequacy ratio may be too high in practice and may require concomitantly a broadening of the perimeter of regulation and a strengthening of financial supervision to prevent disintermediation and distortions in financial markets.
The influence of different wavelengths of LED light on the production of glucosinolates and phenolic compounds and the antioxidant potential in in vitro cultures of Nasturtium officinale (watercress)

Published: August 2021

AbstractCultures of Nasturtium officinale were cultivated in vitro under illumination with different wavelengths of light-emitting diode (LED) light (white LED light—WLED, blue light—B, red light—R, 70% red and 30% blue light—RB, 50% green, 35% red and 15% blue light—RBG, 50% yellow, 35% red and 15% blue light—RBY, 50% far red, 35% red and 15% blue light—RBfR, 50% UV, 35% red and 15% blue light—RBUV, darkness—D), and under white fluorescent light (WF)—control conditions. The study investigated the influence of the applied lighting conditions on biomass growth and the production of glucosinolates, phenolic compounds, as well as photosynthetic pigments, and soluble sugars. The study showed a significant beneficial effect of the RBG light on biomass growth (Gi = 11.81 after 20 days) and the production of glucosinolates. The total glucosinolate content under these conditions increased 5.8 and 1.4 times in comparison with the WF light and D condition, respectively, reaching 237.92 mg 100 g−1 DW. The production of phenolic compounds, sugars, and photosynthetic pigments was comparable to the production under the control conditions. The antioxidant potential of extracts from the cultivated biomass was assessed by the CUPRAC, DPPH, and FRAP assays. Extracts obtained from the biomass of cultures grown under the RBG light had an antioxidant potential similar to that of the control cultures. This is the first report providing evidence of the stimulating effect of light quality on the biomass yield and production of glucosinolates by N. officinale microshoot cultures in vitro.
Tribofilm Formation of Simulated Gear Contact Along the Line of Action
Authors: Bayat Reza , Lehtovaara Arto 
Published: August 2021

Abstract
In this paper, an experimental simulation method was used for evaluating the tribofilm formation in rolling/sliding contact at different points in the line of action. A ball-on-disc test method was employed by which the pressure and slide to roll ratio of gear contact could be simulated. In order to reach a general conclusion, four different oils and two surface roughness were involved in the experiments. The tribofilm evolution was captured using spacer layer interferometry method, and the correlation of tribofilm with the location at the line of action was studied. Results showed that there is a threshold pressure for the tribofilm formation around which the tribofilm growth rate is maximum. Above this threshold pressure, the tribofilm formation is not stable, and the wear is dominant. Below this threshold pressure, the tribofilm growth rate rises by increasing the pressure and the gear contact is safely protected by a stable tribofilm.
