Effects of urbanisation and landscape heterogeneity mediated by feeding guild and body size in a community of coprophilous beetles

Although the impacts of urbanisation on biodiversity are well studied, the precise response of some invertebrate groups remains poorly known. Dung-associated beetles are little studied in an urban context, especially in temperate regions. We considered how landscape heterogeneity, assessed at three spatial scales (250, 500 and 1000 metre radius), mediates the community composition of coprophilous beetles on a broad urban gradient. Beetles were sampled using simple dung-baited traps, placed at 48 sites stratified across three distance bands around a large urban centre in England. The most urban sites hosted the lowest abundance of saprophagous beetles, with a lower mean body length relative to the least urban sites. Predicted overall species richness and the richness of saprophagous species were also lowest at the most urban sites. Ordination analyses followed by variation partitioning revealed that landscape heterogeneity across the urban gradient explained a small but significant proportion of community composition. Heterogeneity data for a 500-metre radius around each site provided the best fit with beetle community data. Larger saprophagous species were associated with lower amounts of manmade surface and improved grassland. Some individual species, particularly predators, appeared to be positively associated with urban or urban fringe sites. This study is probably the first to examine the response of the whole coprophilous beetle community to urbanisation. Our results suggest that the response of this community to urbanisation matches expectations based on other taxonomic groups, whilst emphasising the complex nature of this response, with some smaller-bodied species potentially benefitting from urbanisation

Need Evolutionary Debunking Arguments Rely on a Particular Metaphysical Construal of Evaluative Facts?

Sharon Street’s evolutionary debunking argument—her Darwinian Dilemma—is meant to challenge value realists to reconcile the evaluative attitudes we tend to hold, shaped as they are by evolution, with the attitude-independent evaluative facts that realists posit. Ramon Das argues that Street’s argument relies on illicit metaphysical assumptions about evaluative facts, and that these assumptions beg the question against a particular form of value realism called naturalist realism. I argue that Street makes no such metaphysical assumptions, and that her argument requires no particular metaphysical construal of evaluative facts to work. I further argue that any objection of the kind Das raises—those that turn on the metaphysical underpinnings of evaluative facts—is unlikely to succeed against Street’s Darwinian Dilemma

Theorising globalised production and digitalisation: Towards a re-centring of value

Digital and data-driven technologies are having substantial impacts on global production, with growing analysis within established frameworks such as Global Value Chains (GVC) and Global Production Networks (GPN). Given the claims, however, that digitalization is leading to transformations in the patterns of production and labor, further theoretical work is needed to consider how these frameworks fit with evolving dynamics. Beginning with critiques that mainstream GVC/GPN have poorly theorized the concept of value, the paper argues that a re-centering of value is crucial for improved understanding of digitalization. To do this, broader debates in the literature on the digital economy—on rent and surplus value—are reviewed. These debates provide an expanded perspective of value including a broader understanding of forms of techno-economic rent and the growing debates on heterogeneous forms of labor, shaping production. A stronger orientation towards value within mainstream GVC/GPN studies can absorb some of these ideas, but considering the evolving forms, conventional notions of governance and upgrading may be less viable

Transition of an Effective E-Learning Platform Application of Quality Program Elements into New Environment

This paper describes the strategies and considerations necessary in the transition of a highly effective e-learning teacher certification program for elementary preparation into secondary mathematics and science teacher preparation. The paper will review the effective elements of an existing program in elementary teacher preparation and an effort to make the transition to a secondary program, at a different university, in mathematics and science teacher preparation

Arakabu and the Arakawa Mountain Kami

Under the assumption that religious concepts are like any other concepts, ethnographic studies have been able to provide plausible explanations for a wide range of religious beliefs and behaviour. One under-studied question asks how such concepts help form specific expectations about social life in modern communities. Here, we focus on how a micro-community in a southern Japanese village edits inherited religious concepts to help make solutions to a social problem intelligible. In section one, we study the variables: the religious concept, the problem, and the micro-community. In section two we turn to the details of the editing of the concept
