Michael Elliott CBE. 30 September 1924 — 17 October 2007
Get PDFMichael Elliott was the leader of work at Rothamsted that invented and subsequently commercially developed the pyrethroids, a new class of insecticides. Michael made probably the greatest individual contribution to the control of insect pests that not only constrain global food production but also affect the health of ourselves and our livestock. In one of the first pioneering structure–activity relationship studies, Michael led the multidisciplinary team that invented the major pyrethroid insecticides bioresmethrin, permethrin, cypermethrin and deltamethrin. In the 1980s these represented two-thirds of the global pyrethroid market; at that time pyrethroids captured more than 25% of the total insecticide market and were used on 33 million hectares of crops (Wirtz et al. 2009). In 2002 deltamethrin was the world's largest-selling pyrethroid, with annual sales worth $208 million (information from Cropnosis Ltd). In terms of human health, in 2009 it was estimated that pyrethroid-treated bednets significantly decreased the number of deaths due to malaria among children under five years of age by about one-fifth as well as reducing all incidents of malaria, and in 2011 the World Health Organization recommended its vastly expanded use.ReferenceWirtz, K., Bala, S., Amann, A. & Elbert, A. 2009 A promise extended—future roles of pyrethroids in agriculture.

Representing crime, violence and Jamaica in visual art: An interview with Michael Elliott
Get PDFMichael Elliott is a visual artist based in Jamaica. A number of Elliott’s paintings make explicit reference to Jamaica’s high levels of violent crime; to the entanglement of Jamaican party politics and criminal organizations in what is known as “garrison politics”; and to the so-called “Tivoli Incursion”, the 2010 security operation to capture the criminal don, Christopher “Dudus” Coke, which involved the deaths of sixty-nine residents of Tivoli Gardens and led to a Commission of Enquiry. In this interview, the author invites Elliott to reflect on how his work connects to, and intervenes in, other representations of crime, violence and Jamaica
A typology of marine and estuarine hazards and risks as vectors of change: a review for unstable coasts and integrated coastal management
No full textThis paper illustrates a typology of 14 natural and anthropogenic hazards, the evidence for their causes
and consequences for society and their role as vectors of change in estuaries, vulnerable coasts and
marine areas. It uses hazard as the potential that there will be damage to the natural or human system
and so is the product of an event which could occur and the probability of it occurring whereas the
degree of risk then relates to the amount of assets, natural or societal, which may be affected. We give
long- and short-term and large- and small-scale perspectives showing that the hazards leading to disasters
for society will include flooding, erosion and tsunamis. Global examples include the effects of
wetland loss and the exacerbation of problems by building on vulnerable coasts. Hence we emphasise
the importance of considering hazard and risk on such coasts and consider the tools for assessing and
managing the impacts of risk and hazard. These allow policy-makers to determine the consequences for
natural and human systems. We separate locally-derived problems from large-scale effects (e.g. climate
change, sea-level rise and isostatic rebound); we emphasise that the latter unmanaged exogenic pressures
require a response to the consequences rather than the causes whereas within a management area
there are endogenic managed pressures in which we address both to causes and consequences. The
problems are put into context by assessing hazards and the conflicts between different uses and users
and hence the management responses needed. We emphasise that integrated and sustainable management
of the hazards and risk requires 10-tenets to be fulfilled
Cosmopolitanism and Nationalism in Native American Literature: A Panel Discussion

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
