Abstract This review essay engages with Dorothy Sue Cobble's For The Many: American Feminists and the Global Fight for Democratic Equality from perspective of European histories socialist feminism during Cold War. suggests three themes that might lead to further discussion. These concern first all role left-Catholic as well Social women within networks Cobble describes in Many ; second, influen...
Substrate facies monitoring is critical for the understanding of fluvial geomorphologic and ecohydraulic patterns processes. However, direct substrate measurement time-consuming subjected to data sparsity because small sample, size, limited collections within an area interest, which make it difficult capture patterns. Most new experimental studies focus on mapping based median grain size a spec...
Stereo-video scuba transects were conducted during daylight hours from June to September 2013 within a proposed marine protected area (MPA) in the Firth of Clyde, west of Scotland. More juvenile Atlantic cod Gadus morhua of fork length (LF ) range 6-11 cm were observed in substrata containing mixed gravel, including maerl, than in boulder-cobble substrata with high algal cover, or sand with low...
Sediment transport is an intrinsically stochastic process, and measurement of bed load in the environment is further complicated by the unsteady nature of river flooding. Here we present a methodology for analyzing sediment tracer data with unsteady forcing. We define a dimensionless impulse by integrating the cumulative excess shear velocity for the duration of measurement, normalized by grain...
Short-term effects of bottom trawling on a 'hard-bottom' (pebble, cobble, and boulder) seafloor were studied on the outer continental shelf in the eastern Gulf of Alaska. Eight sites were trawled in August 1996; then, from a research submersible we videotaped each trawl path and a nearby reference transect to obtain quantitative data. Boulders were displaced, and large epifaunal invertebrates w...
The experience of older adults who play video games illustrates the contemporary challenges ageing and strategies that individuals set up to navigate them. ethnography a game workshop dedicated in French cultural centre offers an opportunity examine how group 15 women aged 60–82 years exert their agency as technogenarians (Joyce & Loe 2011). In order fully engage play, workshop’s particip...
Abstract High quality laboratory measurements of nearshore waves and morphology change at, or near prototype-scale are essential to support new understanding coastal processes enable the development validation predictive models. The DynaRev experiment was completed at GWK large wave flume over 8 weeks during 2017 investigate response a sandy beach water level rise varying conditions with withou...
Yuchanyan Cave in Daoxian County, Hunan Province (People's Republic of China), yielded fragmentary remains of 2 or more ceramic vessels, in addition to large amounts of ash, a rich animal bone assemblage, cobble and flake artifacts, bone tools, and shell tools. The artifacts indicate that the cave was a Late Paleolithic foragers' camp. Here we report on the radiocarbon ages of the sediments bas...
Writing in Environmental Health Perspectives (2005), Booth and Zeller [hereafter BZ05] embark on the highly ambitious task of applying ecosystem modeling to the difficult problem of tracing the flow of methylmercury (MeHg) the biologically active, potentially toxic form of mercury in the Faroe Island marine ecosystem as changing functions of both fish mortality (commercial catch rates) and clim...
