We analyzed whole-genome sequencing (WGS) data from 51 populations and combined WGS and array data from 89 populations. Multiple types of polygenic scores (PGS) were employed, derived from multi-ancestry, between-family genome-wide association study (GWAS; MIX-Height), European-ancestry, between-family GWAS (EUR-Height), and European-ancestry siblings GWAS (SIB-Height). Our findings demonstrate that both genetic and environmental factors significantly influence adult body height between populations. Models that included both genetic and environmental predictors best explained population differences in adult body height, with the MIX-Height PGS and environmental factors (Human Development Index [HDI] + per capita caloric intake) achieving an R2 of .83. Our findings shed light on Deaton’s ‘African paradox’, which noted the relatively tall stature of African populations despite poor nutrition and childhood health. Contrary to Deaton’s hypotheses, we demonstrate that both genetic differences and environmental factors significantly influence body height in countries with high infant mortality rates. This suggests that the observed tall stature in African populations can be attributed, in part, to a high genetic predisposition for body height. Furthermore, tests of divergent selection based on the QST (i.e., standardized measure of the genetic differentiation of a quantitative trait among populations) and FST (neutral marker loci) measures exceeded neutral expectations, reaching statistical significance (p < .01) with the MIX-Height PGS but not with the SIB-Height PGS. This result indicates potential selective pressures on body height-related genetic variants across populations.

During the global COVID-19 pandemic, many countries have expanded the level and coverage of current social insurance and social assistance programs as well as implemented new programs. Based on three separate datasets, V-Dem V-Party dataset; fourteen structured expert interviews; and a dataset of 114 social security measures, we study the link between the welfare regime, pandemic-related social policy measures, and incumbents’ ideological stand. Does the pandemic-related social policy measures mirror the political attitudes of the incumbents? What role did the welfare regime play? We scrutinise eight OECD countries (Denmark, Finland, Germany, Netherlands, Norway, Sweden, UK, and the US) representing three different welfare regimes: corporatist-conservative countries, liberal countries, and socio-democratic countries. The key findings of this article show that the pandemic-related social policy measures did not mirror the political attitudes of the incumbents.

A natural population of Vriesea friburgensis var. paludosa was genetically and demographically characterized. Four selected enzymatic systems were used. In total, 10 allozymic loci were analysed. The proportion of polymorphic loci was 70% and the number of alleles per locus was 2.3· The mean observed and expected heterozygosities were 0.234 and 0.226, respectively. An excess of heterozygotes was revealed by the value of the fixation index (—0.035). These indices showed the presence of high levels of genetic diversity in the population studied. A demographic survey revealed almost six times more vegetative than sexually reproductive plants. Reproductive plants were found only in clusters. The genetic diversity exhibited by this population, associated with vegetative as well as sexual propagation, resulting in clusters or colonies, would allow the employment of a sustainable management strategy for species conservation as well as its exploitation as an ornamental.

The use of plant genetic resources (PGR) in crop improvement, followed by adoption, cultivation and consumption or marketing of the improved cultivars by farmers, is one of the most sustainable methods to conserve valuable genetic resources for the future, and simultaneously to increase agricultural production and food security. The objective of this review is to summarize issues related to the use of PGR in crop improvement. Specific topics are: definition of genetic resources for crop improvement; information sources on the internet; documentation and evaluation of PGR; access to PGR, equitable sharing of profits, and material transfer agreements; impediments to the use of PGR in crop improvement; classical methods of using PGR in crop improvement (introgression, incorporation, prebreeding and wide crosses); use of landraces in breeding for specific adaptation to stress environments; utility of molecular markers and genomic research for using PGR in crop improvement (diversity assessment, mapping of quantitative trait loci (QTL) and marker-assisted selection (MAS), advanced backcross QTL analysis and introgression libraries, association studies and direct allele selection); and gene transfer. Practical examples or experimental results are given for most aspects.

Comics are one of the paradigmatic forms of hybrid media, and coming up with a satisfactory definition for it has been difficult. Cowling, S. & Wesley D. C. (2022) take a functional approach and offer an Intentional Picture-Reading View which defines comics as something that is “aptly intended to be picture-read.” I show that the view is extensionally inadequate as is because formally ambitious prose and concrete poetry, too, are aptly intended to be picture-read. The way forward, I argue, is to look at more medium-specific non-depictive images (such as speech balloons and panels) to set comics apart from other hybrid media.

This article explores the potential barriers for emerging composers to constructing and maintaining a career in the field of composition in Scotland, viewed through the lens of both those early in their careers and the experience of others who have worked professionally for many years. Thirty-nine composers responded to a survey that highlighted the role of educational mentoring, the need for monetary stability and the challenges faced by female and older emerging composers. The professional lives of current Scottish composers have been seldom studied, and the purpose of this investigation is to explore, inform and provide suggestions for future consideration.

The COVID-19 pandemic had an unprecedented impact on healthcare systems and exists globally. To control pandemic progression, COVID-19 vaccines were developed and licensed for use in the adult population in early 2021 and became available in paediatric cohorts several months later. Since then, several studies have reported adverse events and severe adverse events in the adult and paediatric cohorts. The question remains whether there exists a significant risk to paediatric COVID-19 vaccination. This study reviews the classification and presentation of severe adverse events and discusses relevant reports in the literature. An emphasis is put on cardiovascular severe adverse events and adverse events. This paper also provides current and future perspectives relative to the pandemic, its control, and the future of vaccine immunology.

Wild bees (Hymenoptera) that visit croplands rely on adjacent habitat to provide essential resources such as pollen, nectar, and nesting locations. This study compared wild bee assemblages on salt marshes and dykes, two coastal habitats proximal to cropland in Nova Scotia, Canada. We hypothesised that dykes would have a greater wild bee abundance and richness compared to salt marshes due to greater floral abundance and richness and nesting habitat availability. Wild bee richness and abundance differences between habitats were not significant. Most notably, Bombus (Latreille) and Megachildae (Latreille) bees were observed visiting a wind-pollinated salt marsh grass, Sporobolus michauxianus (Peterson and Saarela) (Poaceae). Several notable species were also observed, including the Committee on the Status of Endangered Wildlife in Canada species of concern, Bombus terricola (Kirby) (Hymenoptera: Apidae), and Lasioglossum taylorae (Gibbs) (Hymenoptera: Halictidae), a first Nova Scotia record. Floral abundance and richness were significantly greater in dyke habitats. These results contradict other studies that indicate a tight relationship between wild bees and floral abundance and richness. To help conserve these wild bees and their contributions to agriculture, more research is needed to understand how these species use salt marshes and dykes.
