Impact of lifestyle factors on dietary vitamin B6 intake and plasma pyridoxal 5′-phosphate level in UK adults: National Diet and Nutrition Survey Rolling Programme (NDNS) (2008–2017)
Authors: Alsaeedi Asrar , Welham Simon , Rose Peter 
Published: February 2023

AbstractReduction in dietary vitamin B6 intake is associated with an increased relative risk of diseases such as cancer, atherosclerosis and cognitive dysfunction. The current research has assessed vitamin B6 intakes and PLP concentrations as a marker of vitamin B6 status among the UK adult (≥ 19 years) population. This study was carried out using a cross-sectional analysis of the National Diet and Nutrition Survey Rolling Programme (NDNS) (2008–2017). The impacts of lifestyle factors, including type of diet, smoking, alcohol consumption, and commonly used medications grouped by therapeutic usage, were determined, and data were analysed using IBM SPSS®. Results are expressed as medians (25th–75th percentiles), with P values ≤ 0·05 considered statistically significant. Among UK adults, the median intakes of total population of dietary vitamin B6 met the reference nutrient intake and median plasma PLP concentrations were above the cut-off of vitamin B6 deficiency; however, we found an association between reduction in vitamin B6 intake and plasma PLP concentration and age group (P < 0·001). Smokers had significantly lower plasma PLP concentrations than non-smokers (P < 0·001). Moreover, regression analysis showed some commonly used medications were associated with plasma PLP levels reduction (P < 0·05). Taken together, we report on a tendency for dietary vitamin B6 intake and plasma PLP concentrations to decrease with age and lifestyle factors such as smoking and medication usage. This information could have important implications for smokers and in the elderly population using multiple medications (polypharmacy).
How do Voters Form Perceptions of Party Positions?
Authors: Wagner Markus , Meyer Thomas M. 
Published: February 2023

AbstractPolitical debates are structured by underlying conflict dimensions, such as left-right and economic and cultural ideology, which form the basis for voter choice and party competition. However, we know little about how voters arrive at perceptions of parties' positions on these dimensions. We examine how the emphasis parties place on the different issues that make up a higher-level ideological dimension affects perceptions of their position on that dimension. Using two population-based survey experiments, we present respondents with either short or long statements that communicate the same issue stances. We then test whether the length of statements affects positional perceptions on the higher-level dimension. The empirical results show support for our hypotheses and imply that political parties – and the context in which they compete – can affect their perceived position even if underlying issue stances remain stable.
Gill grooming in middle Cambrian and Late Ordovician trilobites
Authors: Hou Jin-bo , Hughes Nigel C. , Hopkins Melanie J. 
Published: February 2023

AbstractEfficient extraction of oxygen from ambient waters played a critical role in the development of early arthropods. Maximizing gill surface area enhanced oxygen uptake ability but, with gills necessarily exposed to the external environment, also presented the issue of gill contamination. Here we document setae inserted on the dorsal surface of walking legs of the benthic-dwelling middle CambrianOlenoides serratusand on the gill shaft of the Late OrdovicianTriarthrus eatoni. Based on their physical positions relative to gill filaments, we interpret these setae to have been used to groom the gills, removing particles trapped among the filaments. The coordination between setae and gill filaments is comparable to that seen among modern crustaceans, which use a diverse set of setae-bearing appendages to penetrate between gill filaments when grooming. Grooming is known relatively early in trilobite evolutionary history and would have enhanced gill efficiency by maximizing the surface area for oxygen uptake.
Explaining the Calendar: The Catholic Church and Family Planning in Poland, 1930–1957
Authors: Jarska Natalia , Kuźma-Markowska Sylwia 
Published: February 2023

AbstractThis article explores continuities and discontinuities in Polish Catholic discourses on family planning across a time span that tends to be divided in the historiography on Poland and political history in general. The period we analyse begins in 1930, with the pivotal encyclical Casti connubii defining church doctrine on contraception, and ends with the legalization of abortion in 1956, and a state-sponsored family planning campaign the following year. In order to reconstruct Catholic teachings on marriage and family planning we examine advice publications that received official church approval, paying particular attention to their gendered dimensions, the emphasis placed on marriage, and the ‘calendar’ method. Although our research includes three politically and socially distinct periods, we argue that the content of Catholic teachings on family planning in Poland was consistent throughout. We also show that, although there were some distinct national characteristics, the Polish Catholic discourse on family planning resembled to a great extent the developments in other countries, particularly in regard to visions of marriage and sexuality. As we delineate, by engaging in the discussion on family planning, Catholic authors acted as active constructors of modernity, construed in both periods in relation to science and nationalism.

AbstractThe milk production is strongly influenced by the dairy cow welfare related to a good nutrition and the analysis of the digestibility of feeds allows us to evaluate the health status of the animals. Through faeces’ visual examination it is possible to estimate the quality of diet fed in terms of lacking in fibre or too high in non-structural carbohydrates. The study was carried out in 2021, on four dairy farms in central Italy. The purpose of this work is the classification and evaluation of dairy cow faeces using RGB image analysis through an artificial intelligence (AI) (convolutional neural network (CNN)) algorithm. The main features to analyse are pH, colour and consistency. For the latter two RGB imaging was combined with deep learning and AI to reach objectivity in samples’ evaluation. The images have been captured with several smartphones and cameras, under various light conditions, collecting a data set of 441 images. Images acquired by RGB cameras are then analysed through CNN technology that extracts features and data previously standardized by a faecal score index assigned after a visual analysis and based on five classes. The results achieved with different training strategies show a training accuracy of 90% and a validation accuracy of 78% of the model which allow us to identify problems in bovine digestion and to intervene promptly in feed variation. The method used in this study eliminates subjectivity in field analysis and allows future improvement of increasing the data set to strengthen the model.
A guide to the AfterDeath: Maimonides on olam ha-ba’
Authors: Stern Josef 
Published: February 2023

AbstractThis article analyses Moses Maimonides' account of the AfterDeath and, more specifically, of olam ha-ba’ (lit.: the world to come), the state of ultimate human happiness and perfection (in contrast to this world). Maimonides is unequivocal about what olam ha-ba’ is not. Contrary to a competing medieval Jewish tradition, it is utterly incorporeal and, contrary to rabbinic tradition, it is not a motivational reward nor compensation for undeserved suffering in a theodicy. Instead, Maimonides gives two positive accounts of the metaphysics of olam ha-ba’. The first is an intellectualist account on which the denizens of olam ha-ba’ are perfected intellects engaged in intellectual apprehension of the deity. The second is sceptical: it denies that humans have any understanding or knowledge (‘ilm, episteme) of olam ha-ba’ and claims that all language used to describe it is purely equivocal or homonymous, although it allows that some immutable thing, whatever it is, survives death. Instead of being a motivational reward or compensation, olam ha-ba’ is the end, that is, final cause or telos, of the best possible human life in this world at which one aims and which one attempts to approximate even if one cannot actually realize it.
A position paper on researching braille in the cognitive sciences: decentering the sighted norm
Authors: Englebretson Robert , Holbrook M. Cay , Fischer-Baum Simon 
Published: February 2023

AbstractThis article positions braille as a writing system worthy of study in its own right and on its own terms. We begin with a discussion of the role of braille in the lives of those who read and write it and a call for more attention to braille in the reading sciences. We then give an overview of the history and development of braille, focusing on its formal characteristics as a writing system, in order to acquaint sighted print readers with the basics of braille and to spark further interest among reading researchers. We then explore how print-centric assumptions and sight-centric motivations have potentially negative consequences, not only for braille users but also for the types of questions researchers think to pursue. We conclude with recommendations for conducting responsible and informed research about braille. We affirm that blindness is most equitably understood as but one of the many diverse ways humans experience the world. Researching braille literacy from an equity and diversity perspective provides positive, fruitful insights into perception and cognition, contributes to the typologically oriented work on the world’s writing systems, and contributes to equity by centering the perspectives and literacy of the people who read and write braille.

Abstract
After the winter of 2021/2022, the coronavirus disease 2019 (COVID-19) pandemic had reached a phase where a considerable number of people in Germany have been either infected with a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant, vaccinated or both, the full extent of which was difficult to estimate, however, because infection counts suffer from under-reporting, and the overlap between the vaccinated and recovered subpopulations is unknown. Yet, reliable estimates regarding population-wide susceptibility were of considerable interest: Since both previous infection and vaccination reduce the risk of severe disease, a low share of immunologically naïve individuals lowers the probability of further severe outbreaks, given that emerging variants do not escape the acquired susceptibility reduction. Here, we estimate the share of immunologically naïve individuals by age group for each of the sixteen German federal states by integrating an infectious-disease model based on weekly incidences of SARS-CoV-2 infections in the national surveillance system and vaccine uptake, as well as assumptions regarding under-ascertainment. We estimate a median share of 5.6% of individuals in the German population have neither been in contact with vaccine nor any variant up to 31 May 2022 (quartile range [2.5%–8.5%]). For the adult population at higher risk of severe disease, this figure is reduced to 3.8% [1.6%–5.9%] for ages 18–59 and 2.1% [1.0%–3.4%] for ages 60 and above. However, estimates vary between German states mostly due to heterogeneous vaccine uptake. Excluding Omicron infections from the analysis, 16.3% [14.1%–17.9%] of the population in Germany, across all ages, are estimated to be immunologically naïve, highlighting the large impact the first two Omicron waves had until the beginning of summer in 2022. The method developed here might be useful for similar estimations in other countries or future outbreaks of other infectious diseases.
Welfare of dairy cows in Kosovo and intervention thresholds for selected welfare indicators as suggested by farmers and veterinarians

AbstractDespite increased concerns about dairy cattle welfare, there is a paucity of knowledge regarding their welfare and the attitudes of farmers and veterinarians in the Western Balkan region. This is the first on-farm study to address dairy cattle welfare and the attitudes of farmers and veterinarians towards animal welfare in Kosovo. Thirty tie-stall dairy farms across seven Kosovo regions were assessed twice with an interval of 10 to 12 months. During the first visit, the Welfare Quality® assessment protocol was applied, whilst the second visit focused on clinical animal-based indicators and interviews with the farmers regarding intervention thresholds for a number of welfare indicators. Additionally, such thresholds were obtained from 15 veterinarians via an online questionnaire. The main areas of concern that were highlighted relate to comfort around resting (soiling of animals, restriction of lying down movements) and injuries, including lameness. Farmers and veterinarians agreed on the intervention thresholds for the majority of the indicators (eg animals with dirty udders, animals with lesions/swellings) but differences were found for important health and welfare issues (eg farmers suggesting a higher threshold for lameness compared to veterinarians). Compared to the on-farm prevalences, both farmers and veterinarians suggested lower intervention levels for welfare issues indicating an awareness of problems. In conclusion, investments into close co-operation between farmers, veterinarians and other advisors regarding awareness-building and inducing changes in daily management routines are considered necessary to improve dairy cow welfare.
China's First Recital and Recording Pianist Ding Shande: A Critical Examination of His Performing Career and Performance Style
Authors: ZHOU DANNY 
Published: February 2023

AbstractMusical biography, particularly that which focuses on non-Western performers, has long been marginalized in musicology. This article critically examines the performing career and performance style of China's first recital and recording pianist, Ding Shande, by scrutinizing written documents and analysing recordings. It was found that Ding's performing career was short-lived, peaking in 1935 and ending in the 1950s, and that he tended to play with fast and even tempo, emphasize metrical organizations, and highlight structural divisions through long-range dynamic variation. These findings shed light on how the changing concept of semi-colonialism influenced the career trajectories and performance styles of the earliest Chinese pianists, and hence offer insights into early history of piano performance in China. This article shows that performers’ performances are just as important in biographical writings as is the story of their lives, and that interweaving the two helps develop a more thorough and comprehensive understanding of a performer's biography.
The promise and limitations of Hong Kong's Women's Commission as a vehicle to drive gender equality
Authors: Barrow Amy 
Published: February 2023

AbstractDrawing on a qualitative study of Hong Kong's Women's Commission (‘WoC’), this article examines how institutional mechanisms for the advancement of women function in a hybrid regime that includes both democratic and authoritarian elements. Hong Kong has a rights-based legal framework and equality agencies that support the operation of equality laws and policies. Paradoxically, Hong Kong's political system is non-democratic, and Beijing's Central People's Government is exerting more direct control on the territory. Grounded in qualitative interviews conducted with WoC members, non-governmental organisations, and scholars in Hong Kong, this article concludes that the WoC's full institutional potential in drawing attention to gender inequalities has not been realised. The implementation of authoritarian governance practices also has implications for the WoC's composition and agenda and may inhibit the development of progressive gender equality strategies to advance the status of women.
Artificial Upwelling—A Refined Narrative
Authors: Jürchott M. , Oschlies A. , Koeve W. 
Published: February 2023

AbstractThe current narrative of artificial upwelling (AU) is to translocate nutrient rich deep water to the ocean surface, thereby stimulating the biological carbon pump (BCP). Our refined narrative takes the response of the solubility pump and the CO2 emission scenario into account. Using global ocean‐atmosphere model experiments we show that the effectiveness of a hypothetical maximum AU deployment in all ocean areas where AU is predicted to lower surface pCO2, the draw down of CO2 from the atmosphere during years 2020–2100 depends strongly on the CO2 emission scenario and ranges from 1.01 Pg C/year (3.70 Pg CO2/year) under RCP 8.5 to 0.32 Pg C/year (1.17 Pg CO2/year) under RCP 2.6. The solubility pump becomes equally effective compared to the BCP under the highest emission scenario (RCP 8.5), but responds with CO2 outgassing under low CO2 emission scenarios.
A Case of Anomalous Electric Field Perturbations in the Equatorial Ionosphere During Postsunset Hours: Insights

AbstractDuring a weak geomagnetic storm (Ap = 15) on 24 December 2014, the penetration electric field perturbations over the Indian dip equatorial sector are found to be anomalous on a number of occasions during postsunset hours. The event is anomalous as the magnitude and polarity of penetration electric fields do not obey the existing paradigm. The penetration electric field perturbations are investigated using the vertical drifts derived from the CADI (Canadian Advanced Digital Ionosonde) measurements at Tirunelveli (8.7°N, 77.7°E, dip angle: 1.7°). During this event, we observed postsunset vertical drift of ∼42 m s−1 not only at 18:10 LT but also ∼36 m s−1 at ∼21:00 LT which is anomalous. Interestingly, the dawn‐dusk component of interplanetary electric field (IEFy) is relatively less (<2 mV/m) at ∼21:00 LT compared to the interval 19:30–20:30 LT (IEFy ∼3 mV/m). Despite that, the vertical drift observed over Tirunelveli is very close to zero or nominally upward during 19:30–20:30 LT. In addition, the downward drift just after 21:30 LT on this night is found to be exceptionally large (∼−60 m s−1). By combining vertical total electron content over the Indian sector with the OI 630.0 nm airglow intensity from Mt. Abu, chain of magnetometer and Los Alamos National Laboratory geosynchronous satellite particle measurements, it is suggested that the anomalous penetration electric field perturbations on this night arise from the effects of interplanetary magnetic field By and substorm.
Beamforming of Rayleigh and Love Waves in the Course of Atlantic Cyclones

Published: February 2023

AbstractThe main sources of the ambient seismic wavefield in the microseismic frequency band (peaking in the ∼0.04–0.5 Hz range) are earth's oceans, namely the wind‐driven surface gravity waves (SGW) that couple oscillations into the seafloor and the upper crust underneath. Cyclones (e.g., hurricanes, typhoons) and other atmospheric storms are efficient generators of high ocean waves that in turn generate distinct microseismic signatures. In this study, we perform a polarization (i.e., three‐component) beamforming analysis of microseismic (0.05–0.16 Hz) retrograde Rayleigh and Love waves during major Atlantic hurricanes using a virtual array of seismometers in Eastern Canada. Oceanic hindcasts and meteorological data are used for comparison. No continuous generation of microseism along the hurricane track is observed but rather an intermittent signal generation. Both seismic surface wave types show clear cyclone‐related microseismic signatures that are consistent with a colocated generation at near‐coastal or shallow regions, however the Love wavefield is comparatively less coherent. We identify two different kinds of intermittent signals: (a) azimuthally progressive signals that originate with a nearly constant spatial lag pointing toward the trail of the hurricanes and (b) azimuthally steady signals remaining nearly constant in direction of arrival even days after the hurricane significantly changed its azimuth. This high complexity highlights the need for further studies to unravel the interplay between site‐dependent geophysical parameters, SGW forcing at depth and microseismic wavefield radiation and propagation, as well as the potential use of cyclone microseisms as passive natural sources.
Mechanical Modeling of Pre‐Eruptive Magma Propagation Scenarios at Calderas
Authors: Mantiloni L. , Rivalta E. , Davis T. 
Published: February 2023

AbstractSimulating magma propagation pathways requires both a well‐calibrated model for the stress state of the volcano and models for dike advance within such a stress field. Here, we establish a framework for calculating computationally efficient and flexible magma propagation scenarios in the presence of caldera structures. We first develop a three‐dimensional (3D) numerical model for the stress state at volcanoes with mild topography, including the stress induced by surface loads and unloading due to the formation of caldera depressions. Then, we introduce a new, simplified 3D model of dike propagation. Such a model captures the complexity of 3D magma trajectories with low running time, and can backtrack dikes from a vent to the magma storage region. We compare the new dike propagation model to a previously published 3D model. Finally, we employ the simplified model to produce shallow dike propagation scenarios for a set of synthetic caldera settings with increasingly complex topographies. The resulting synthetic magma pathways and eruptive vent locations broadly reproduce the variability observed in natural calderas.
