University Teachers’ Conceptions of Their Role as Developers of Technology-Rich Learning Environments

2017

This phenomenographic study examines how a diverse group of university teachers conceptualised their role as developers of technology-rich learning environments at one university in Finland. The research findings illustrate a variety of conceptions. Five qualitatively different ways of understanding teachers’ roles regarding the development of technology-rich learning environments were found: 1) innovator, 2) early adopter, 3) adaptive, 4) sceptic and 5) late adopter. In order to connect the whole set of interconnected roles to a theory of change, Everett Rogers’ innovation diffusion theory was exploited in the last phase of analysis. Finally, hierarchically structured categories were creat…

Book Clubs and Book Commerce

2019

In the twentieth century, cumulative millions of readers received books by mail from clubs like the Book-of-the-Month Club, the Book Society or Bertelsmann Club. This Element offers an introduction to book clubs as a distribution channel and cultural phenomenon, and shows that book clubs and book commerce are linked inextricably. It argues that a global perspective is necessary to understand the cultural and economic impact of book clubs in the twentieth and into the twenty-first century. It also explores central reasons for book club membership, condensing them into four succinct categories: convenience, community, concession and, most importantly, curation. This title is also available as…

Women reduced the sex difference in open-water ultra-distance swimming - La Traversee Internationale du Lac St-Jean, 1955-2012

2014

In La Traversée Internationale du Lac St-Jean, held between 1955 and 2012 in Canada, the fastest women (r2 = 0.61, p < 0.0001) and men (r2 = 0.66, p < 0.0001) improved swimming speed over the years but the sex difference remained unchanged at 8.8% ± 5.6% (r2 = 0.069, p = 0.065). Annually, for the 3 fastest swimmers, both women (r2 = 0.53, p < 0.0001) and men (r2 = 0.71, p < 0.0001) improved swimming speed between 1973 and 2012 and the sex difference decreased (r2 = 0.29, p = 0.0016) from 14.4% ± 11.0% (1973) to 3.7% ± 1.4% (2012).

Formation of 2,4,6-trichlorophenol and 2,4,6-trichloroanisole during treatment and distribution of drinking water

1995

Biomethylation of 2,4,6-trichlorophenol to the potent off-flavour compound 2,4,6-trichloroanisole has previously been found to cause taste and odour problems in drinking water. In the present study, both compounds were detected in seemingly unpolluted surface waters. However, the highest concentrations of 2,4,6-trichloroanisole in tap water were caused by the formation of 2,4,6-trichlorophenol during chlorine disinfection of drinking water and subsequent methylation of this compound in the distribution system. Analysis of samples from several sites in the investigated distribution systems showed that there was a substantial spatial and temporal variation of the concentration of both 2,4,6-t…

Influence of resource quality on the composition of soil decomposer community in fragmented and continuous habitat

2004

Abstract The aim of this field experiment was to explore the combined effects of two factors potentially affecting the local composition of soil decomposer community: resource quality and habitat fragmentation. We created humus (habitat) patches with three different resource quality: (1) pure homogenised humus; (2) humus enriched with needle litter; and (3) humus enriched with needle and leaf litter. These patches were embedded either in a mineral soil matrix, thus representing fragmented habitat, or in natural forest soil, representing continuous (non-fragmented) habitat. The development of faunal (colonisations/extinctions of soil animal populations) and microbial communities in the patch…

Effect of mycorrhizal inoculation on metal accumulation by poplar leaves at phytomanaged sites

2017

Abstract Phytotechnologies for the management of lands contaminated with potentially toxic elements (PTEs) are considered as gentle alternatives to conventional remediation techniques. During the last few years, phytotechnologies have progressively shifted to phytomanagement, a concept that includes the valorization of the plant biomass produced on the contaminated site. This study aimed at evaluating the mid-term effect of ecto- and endomycorrhizal inoculation on the reduction of PTE mobility in soils and foliar accumulation by two poplar clones, Skado ( Populus trichocarpa x P. maximowiczii ) and I-214 ( P. deltoides x P. nigra ), dedicated to bioenergy purposes. The effects of inoculatio…
