Cosmopolitan nationalism and the cultural reach of the white British

In recent years, strong claims have been made for the breakdown of national boundaries and the reformation of national identities in an increasingly interconnected global world – driven in large part by the possibilities and limitations that emerge from an increasingly global media world. It has been argued that new postnational, cosmopolitan subjectivities accompany, enable and feed off globally oriented forms of cultural consumption. This article examines these claims in the light of unusually comprehensive data on the tastes of the white British population collected in a large national sample survey, in-depth interviews and focus groups. By identifying and analysing the geographical spread of the cultural referents of the tastes of the white British we make an empirical assessment of the claims for cosmopolitan identities. We argue that if white British identities are being reformed by processes of globalisation it is, paradoxically, in an increasingly Anglophone direction

Catchment characteristics and seasonality control the composition of microbial assemblages exported from three outlet glaciers of the Greenland Ice Sheet

Glacial meltwater drains into proglacial rivers where it interacts with the surrounding landscape, collecting microbial cells as it travels downstream. Characterizing the composition of the resulting microbial assemblages in transport can inform us about intra-annual changes in meltwater flowpaths beneath the glacier as well as hydrological connectivity with proglacial areas. Here, we investigated how the structure of suspended microbial assemblages evolves over the course of a melt season for three proglacial catchments of the Greenland Ice Sheet (GrIS), reasoning that differences in glacier size and the proportion of glacierized versus non-glacierized catchment areas will influence both the identity and relative abundance of microbial taxa in transport. Streamwater samples were taken at the same time each day over a period of 3 weeks (summer 2018) to identify temporal patterns in microbial assemblages for three outlet glaciers of the GrIS, which differed in glacier size (smallest to largest; Russell, Leverett, and Isunnguata Sermia [IS]) and their glacierized: proglacial catchment area ratio (Leverett, 76; Isunnguata Sermia, 25; Russell, 2). DNA was extracted from samples, and 16S rRNA gene amplicons sequenced to characterize the structure of assemblages. We found that microbial diversity was significantly greater in Isunnguata Sermia and Russell Glacier rivers compared to Leverett Glacier, the latter of which having the smallest relative proglacial catchment area. Furthermore, the microbial diversity of the former two catchments continued to increase over monitored period, presumably due to increasing hydrologic connectivity with proglacial habitats. Meanwhile, diversity decreased over the monitored period in Leverett, which may have resulted from the evolution of an efficient subglacial drainage system. Linear discriminant analysis further revealed that bacteria characteristic to soils were disproportionately represented in the Isunnguata Sermia river, while putative methylotrophs were disproportionately abundant in Russell Glacier. Meanwhile, taxa typical for glacierized habitats (i.e., Rhodoferax and Polaromonas) dominated in the Leverett Glacier river. Our findings suggest that the proportion of deglaciated catchment area is more influential to suspended microbial assemblage structure than absolute glacier size, and improve our understanding of hydrological flowpaths, particulate entrainment, and transport

“Growing your own herbs” and “cooking from scratch”: Contemporary discourses around good mothering, food, and class‐related identities

In a cultural climate of “intensive parenting” and concerns about the “obesity epidemic,” parents are expected to take responsibility for their children's health, particularly through the provision of a “healthy” diet. This study involved intergenerational dyad interviews with both middle‐class and working‐class mothers and daughters from the United Kingdom. Analysing the data using discourse analysis informed by feminist poststructuralist theory, we found that mothers were positioned as having prime responsibility for the nurturing of family members, including the provision of a healthy diet. However, providing a healthy diet alone was insufficient; mothers needed to demonstrate that time and effort had been taken in the preparation of meals using fresh ingredients. Those who failed to do so were positioned as “lazy,” thus inviting the blaming of mothers for any current or future health problems encountered by family members (especially children). However, talk from some of the working‐class mothers pointed to the unattainable and “classed” ideals that are set by such cultural expectations

What does it mean when people call a place a shithole? Understanding a discourse of denigration in the United Kingdom and the Republic of Ireland

This paper investigates what people mean when they engage in the discourse of denigration. Building on existing literature on territorial stigmatisation that either focuses on macro‐scale uses and effects of territorial stigmatisation or micro‐scale ethnographic studies of effects, we develop a novel approach that captures the diverse voices that engage in the discourse of denigration by tracing the use of the word and hashtag “shithole” on the social media platform Twitter in order to examine who is engaged in the stigmatising discourse, the types of place that are stigmatised and the responses to stigmatised places. Using a robust data set, we highlight two key findings. First, the majority of tweets were aimed at places where the tweeter was not from, a form of othering consistent with how territories are stigmatised by those in positions of power such as policymakers, politicians and journalists. Second, we note that an important and gendered minority of tweets can be characterised by a “cry for help” and powerlessness, where the stigma is aimed at their own places. We offer an interpretive lens through which to understand and frame these minoritarian voices by engaging with theories of abjection that allow us to see how minoritarian voices relate to place

Natural history of Arabidopsis thaliana and oomycete symbioses

Molecular ecology of plant–microbe interactions has immediate significance for filling a gap in knowledge between the laboratory discipline of molecular biology and the largely theoretical discipline of evolutionary ecology. Somewhere in between lies conservation biology, aimed at protection of habitats and the diversity of species housed within them. A seemingly insignificant wildflower called Arabidopsis thaliana has an important contribution to make in this endeavour. It has already transformed botanical research with deepening understanding of molecular processes within the species and across the Plant Kingdom; and has begun to revolutionize plant breeding by providing an invaluable catalogue of gene sequences that can be used to design the most precise molecular markers attainable for marker-assisted selection of valued traits. This review describes how A. thaliana and two of its natural biotrophic parasites could be seminal as a model for exploring the biogeography and molecular ecology of plant–microbe interactions, and specifically, for testing hypotheses proposed from the geographic mosaic theory of co-evolution

Defining and averting syndemic pathways in aquaculture: a major global food sector

Aquaculture now provides half of all aquatic protein consumed globally—with most current and future production occurring in low- and middle-income countries (LMICs). Concerns over the availability and application of effective policies to deliver safe and sustainable future supply have the potential to hamper further development of the sector. Creating healthy systems must extend beyond the simple exclusion of disease agents to tackle the host, environmental, and human drivers of poor outcomes and build new policies that incorporate these broader drivers. Syndemic theory provides a potential framework for operationalizing this One Health approach

Chromosomal-level assembly of the Asian Seabass genome using long sequence reads and multi-layered scaffolding

We report here the ~670 Mb genome assembly of the Asian seabass (Lates calcarifer), a tropical marine teleost. We used long-read sequencing augmented by transcriptomics, optical and genetic mapping along with shared synteny from closely related fish species to derive a chromosome-level assembly with a contig N50 size over 1 Mb and scaffold N50 size over 25 Mb that span ~90% of the genome. The population structure of L. calcarifer species complex was analyzed by re-sequencing 61 individuals representing various regions across the species' native range. SNP analyses identified high levels of genetic diversity and confirmed earlier indications of a population stratification comprising three clades with signs of admixture apparent in the South-East Asian population. The quality of the Asian seabass genome assembly far exceeds that of any other fish species, and will serve as a new standard for fish genomics
