Eco-crime and fresh water
No full textThe unsustainable and exploitative use of one of the most important but scarce resources on the planet - freshwater - continues to create conflict and human dislocation on a grand scale. Instead of witnessing nation-states adopting more equitable and efficient conservation strategies, powerful corporations are permitted to privatise and monopolise diminishing water reservoirs based on flawed neo-liberal assumptions and market models of the ‘global good’. The commodification of water has enabled corporate monopolies and corrupt states to exploit a fundamental human right, and in the process have created new forms of criminality. \ud

In recent years, affluent industrialised nations have experienced violent rioting as protestors express opposition to government ‘freshwater taxes’ and to corporate investors seeking to privatise drinking water. These water conflicts have included unprecedented clashes with police and deaths of innocent civilians in South Africa (BBC News, 2014a); the United Nations intervention in Detroit USA after weeks of public protest (Burns, 2014); and the hundreds of thousands of people protesting in Ireland (BBC News, 2014,b; Irish Times 2015). Subsequently, the commodification of freshwater has become a criminological issue for water-abundant rich states, as well as for the highly indebted water-scarce nations
Why Nigel Farage is unlikely to get his referendum on the government’s net-zero plans
No full textThe Johnson Government is in the process of rebranding its policy on net-zero as a quest for energy independence from Putin’s Russia, writes Derrick Wyatt, which may lead to a short-term emphasis on domestic oil and gas production, but increased focus on nuclear and renewables. This will all be consistent with the Paris Agreement on Climate Change, which is a key commitment in the UK’s trade deal with the EU. Nigel Farage’s call for a referendum on net-zero by 2050 is likely to fall by the wayside
Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
Ep. #181 - Nigel Clark
No full textThis recording and transcript form part of a collection of podcasts conducted by the Cultures of Energy at Rice University. Cultures of Energy brings writers, artists and scholars together to talk, think and feel their way into the Anthropocene. We cover serious issues like climate change, species extinction and energy transition. But we also try to confront seemingly huge and insurmountable problems with insight, creativity and laughter.Cymene and Dominic discuss a strange effort to police sugar packet play on this week’s podcast. Then (15:52) we are delighted to welcome Nigel Clark to the conversation. Nigel is Chair of Social Sustainability and Human Geography at Lancaster University (https://www.lancaster.ac.uk/lec/about-us/people/nigel-clark ). He is the author of Inhuman Nature: Sociable Life on a Dynamic Planet (2011) and co-editor of Atlas: Geography, Architecture and Change in an Interdependent World (2012), Material Geographies (2008) and Extending Hospitality(2009). We start things off by talking about a new book he is working on called The Anthropocene and Societythat he is working on with Bron Szerszynski and what it means to rethink humanity through planetary strata, flows, and multiplicity. We turn from there to Australian feminism, phosphates, Aotearoa New Zealand as a space of settler grassland experiments, wealth, and geocide. Then we touch on fire and its excess, our brittle life on an earth’s surface caught between solar and geothermal vitalities, metamorphosis, the early connection between gunpowder and combustion engines and European geotrauma. A special birthday week shout-out to our very own eternal Cymene Howe :

Marais / Malaise trap [NMNW, type catalogue number T 657]. Paratypes: 3 ΨΨ, same data as the holotype [BMNH, MZUR, NMNW]. 1 Ψ, Namibia: OTJINENE DISTRICT / Epukiro River, 3 Km N at: / 21 ° 22 ’ 26 ’’S 20 °06’09’’E / 09– 11.ii. 2001 / A.H. KirkSpriggs & E. Marais / Malaise trap sample [NMNW]. Etymology Named after the type locality “Hamoye”, Rundu District, Namibia. Diagnosis Females of E. hamoyensis differ from those of E. apicalis in lacking a pair of proclinate orbital setae, having just one pair of reclinate upper orbital setae, and much weaker paired median discal setae on abdominal tergites 3–5, those on tergite 3 being sometimes absent. Also, E. hamoyensis has a paler grey appearance than E. apicalis because the four dark vittae on the scutum are less conspicuous and the dark hind margins of the abdominal tergites are significantly narrower. Males of this species are currently unknown. Description Colour. Head mainly black in ground colour except gena, with a paler yellowish colouration and a darker reddishbrown spot adjacent to vibrissa; gena, parafacial and parafrontal areas covered with silvergrey microtrichosity; scape and pedicel mostly blackish, but pedicel paler brownishred on inner surface apically; postpedicel mainly black, but narrowly dull reddishbrown on inner surface near base; arista mostly dark but with paler yellowish area on basal third except for thickened area at base which is darkened; palpus mostly yellow but somewhat darker basally. Thorax and legs entirely black in ground colour; scutum silvergrey microtrichose with four rather faint longitudinal darker vittae which are somewhat more conspicuous presuturally. Lower and upper calypters white. Wing hyaline; tegula and basicosta both brownishblack, basicosta somewhat paler.

Wound myiasis in a wild boar by Lucilia caesar (Diptera: Calliphoridae): First case and current status of animal myiasis by this species
No full textThe first case of myiasis caused by Lucilia caesar (L.) (Diptera: Calliphoridae) in a wild boar, Sus scrofa L. (Artiodactyla: Suidae) is described. The myiasis occurred in October 2019 in Southern Italy and the identification of the agent was based on adult male morphology. The wild boar had a wound on its right side, near the neck, which was largely infested by larvae. The ecology, distribution and current literature status about cases of animal myiasis by this species is also included
