Comparison of House Spraying and Insecticide-Treated Nets for Malaria Control.
No full textThe efficacies of using residual house spraying and insecticide-treated nets against malaria vectors are compared, using data from six recent comparisons in Africa, Asia and Melanesia. By all the entomological and malariological criteria recorded, pyrethroid-treated nets were at least as efficacious as house spraying with dichlorodiphenyltrichloroethane (DDT), malathion or a pyrethroid. However, when data from carefully monitored house spraying projects carried out between the 1950s and 1970s at Pare-Taveta and Zanzibar (United Republic of Tanzania), Kisumu (Kenya) and Garki (Nigeria) are compared with recent insecticide-treated net trials with apparently similar vector populations, the results with the insecticide-treated nets were much less impressive. Possible explanations include the longer duration of most of the earlier spraying projects and the use of non-irritant insecticides. Non-irritant insecticides may yield higher mosquito mortalities than pyrethroids, which tend to make insects leave the site of treatment (i.e. are excito-repellent). Comparative tests with non-irritant insecticides, including their use on nets, are advocated. The relative costs and sustainability of spraying and of insecticide-treated net operations are briefly reviewed for villages in endemic and epidemic situations and in camps for displaced populations. The importance of high population coverage is emphasized, and the advantages of providing treatment free of charge, rather than charging individuals, are pointed out
"Historian of the spirit": an introduction to the life and ideas of Christopher H. Dawson, 1889-1970
No full textWhat follows is an intellectual biography of the English Catholic historian Christopher Henry Dawson (1889-1970). If there is one overarching thesis to this dissertation, it is that Dawson's place within the history of Britain and the United States and within the historical academy in general has been hitherto underappreciated as a result of unfair categorization of his work by critics, and equally unhelpful credulous assessments imd subsequent politicization of his scholarship by overzealous admirers. Even though his perspectives will probably never be completely embraced by the historical academy due to current trends in historiography, it is hoped that this dissertation will demonstrate that Dawson’s scholarship is deserving of study because of the breadth of his intellectual and practical activity in Britain during the twentieth century, and his groundbreaking role in identifying the importance of culture and religious belief to historiography. The introduction includes a review of the most important secondary literature about Dawson that will be used throughout the work. The main text of the dissertation develops chronologically, and is in eight parts, each part representing a distinct phase of Dawson's life. Part Chie (1889-1914) examines the formative years of his childhood, his education, his conversion to the Roman Catholic Church, and how his experiences formed the basis for his opinions about history, religion, and world around him. Part Two (1915-1929) explores the schools of thought that shaped Dawson’s ideas as a young scholar, and the ideas expressed in his first two books. Part Three (1930-1934) represents the most active time of Dawson's career, and the period during which he became a widely read Catholic intellectual and historian of Europe. Part Four (1935-1939) examines Dawson's commentaries on European political movements during the 1930ร. Part Five (1940-1945) discusses Dawson's role as the vice-president of die wartime ecumenical movement 'The Sword of the Spirit', as well as his book written at the height of the Movement's success. Part Six (1946-1952) covers Dawson's ideas from his Gifford Lectures, and his interest in American Catholicism. Part Seven (1953-1962) covers Dawson's vision for American Catholics and education, and his position at Harvard University, which he held from 1958 until a series of strokes forced him to retire, and return to England in 1962. Part Eight (1963-1970) briefly discussed the events of the last years of his life. The conclusion serves as a summary of his contribution and legacy as a major twentieth-century intellectual
Common greenbrier (Smilax rotundifolia L.) as a model for understanding fungal community organization in the phyllosphere
No full textFungi asymptomatically infect all terrestrial vegetation, but the structure and assembly of these fungal communities are poorly understood. Smilax rotundifolia, a common woody vine of the northeastern United States, was used as a model to study endophytic (internal colonizing) and epiphytic (surface colonizing) fungal communities, from the perspectives of niche-based influences, spatial variation, and evolutionary relationships. Wild greenbrier plants were sampled in New Jersey (USA) in late winter at a single site, and again in mid-summer, in a multi-site, multi-tissue, sampling effort. Fungal communities of the plant surface and interior were made up of mostly different species. Correlative relationships were found between some fungal species' abundances, but none were seen between species that were strongly restricted to the surface and those strongly restricted to the interior. The summer, multi-site study, revealed that the strongest factor determining fungal community composition was surface vs. interior habitat, followed by tissue/organ type, and lastly general geographic location. The effect of season was also studied by comparing the single-site winter dataset against the data from the same site sampled in summer. Season had a major influence on some fungal species but not others, similar to influence of tissue type. Also, in a very novel finding, it was found that certain endophytes showed statistically different abundances, depending on the distance from the stem base at which a sample was taken. The optimum height differed for different fungal species. At the scale of a single stand of plants, it was found that epiphytic, but not endophytic, samples showed a significant correlation between spatial proximity and fungal community similarity. Finally, the phylogenetic relationships were studied between congeneric fungal species that were common on the plant. Two-gene phylogenies were constructed using Smilax-derived isolates, along with downloaded sequences of well-defined species in the same genera. These congeneric species were found to be only distantly related (i.e., they were widely separated within the known phylogenies of their genus). The final chapter is a literature review, bringing insight from the present dissertation research to identify important unanswered questions. Evidence for the role of plant secondary metabolites on endophytic fungi is discussed.Ph.D.Includes bibliographical referencesby Christopher B. Zambel
Distribution, density, and habitat associations of the narrowly endemic coldwater crayfish (faxonius eupunctus) in the Eleven Point River drainage, Arkansas and Missouri, U.S.
No full textNorth America harbors an exceptionally high number of rare or narrowly distributed crayfishes, and many of these species are threatened with displacement by a variety of biological, chemical, and physical factors. Detailed distributional and ecological data are lacking for many North American crayfishes, making the assignment of appropriate conservation protection designations difficult. A better understanding of the distribution, population densities, and habitat associations of rare and narrowly distributed crayfishes is therefore warranted to most effectively protect and manage these species. The purpose of this research was to assess the distribution and local population densities of the narrowly endemic Coldwater Crayfish (Faxonius eupunctus) in the Eleven Point River drainage, Arkansas and Missouri, U.S. My principle objectives were to: (1) assess the distribution of F. eupunctus within the Eleven Point River drainage to further evaluate its potential use of tributary streams; (2) estimate local F. eupunctus population densities to determine where the species is most abundant; and (3) investigate physical habitat variables relating to, and potentially influencing, local F. eupunctus densities. I used multiple sampling approaches, including environmental DNA sampling, to assess the distribution, density, and habitat of F. eupunctus throughout the Eleven Point River drainage. Faxonius eupunctus occurred primarily in the main stem Eleven Point River but was detected in a downstream reach of one of its largest tributary streams. Faxonius eupunctus site densities were highest in the middle reaches of the species’ range in the main stem Eleven Point River, and my analyses showed that F. eupunctus density was strongly related to current velocity, in-stream temperature, and streambed substrate size. Results from this study corroborate evidence from previous research in supporting that F. eupunctus is restricted to large streams within its range. Further, I present new evidence that F. eupunctus is most abundant in the middle reaches of its range in the main stem Eleven Point River, and I discuss a variety of local-scale physical habitat variables potentially influencing this noteworthy spatial abundance pattern. I also present support for the use of environmental DNA for the detection of rare lotic-dwelling crayfish species, although I highlight potential limitations of eDNA applications in lotic environments.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2019-12-01The student, Christopher Rice, accepted the attached license on 2017-12-11 at 16:08.The student, Christopher Rice, submitted this Thesis for approval on 2017-12-12 at 11:08.This Thesis was approved for publication on 2017-12-14 at 13:05.DSpace SAF Submission Ingestion Package generated from Vireo submission #11942 on 2018-03-13 at 09:57:44Made available in DSpace on 2018-03-13T15:28:42Z (GMT).

Publishing Translations in Fascist Italy
No full textIn the 1930s translation became a key issue in the cultural politics of the Fascist regime due to the fact that Italy was publishing more translations than any other country in the world. Making use of extensive archival research, the author of this new study examines this 'invasion of translations' through a detailed statistical analysis of the translation market. The book shows how translations appeared to challenge official claims about the birth of a Fascist culture and cast Italy in a receptive role that did not tally with Fascist notions of a dominant culture extending its influence abroad. The author shows further that the commercial impact of this invasion provoked a sustained reaction against translated popular literature on the part of those writers and intellectuals who felt threatened by its success. He examines the aggressive campaign that was conducted against the Italian Publishers Federation by the Authors and Writers Union (led by the Futurist poet F. T. Marinetti), accusing them of favouring their private profit over the national interest. Finally, the author traces the evolution of Fascist censorship, showing how the regime developed a gradually more repressive policy towards translations as notions of cultural purity began to influence the perception of imported literature
UPGMA dendrogram based on the Bray-Curtis dissimilarity matrix on Day 0.
No full text<p>The Bray-Curtis dissimilarity metric takes into account the presence and absence of taxa and the relative abundances of the taxa, to generate a dissimilarity matrix for the faecal microbiota present in samples from horses on Day 0. The UPGMA dendrogram shows distinct clustering of horses (H; numbered from 1–6 per group) by group, indicating that the faecal bacterial community structure of horses on Day 0 differed between Group A (GA) and Group B (GB), which were fed Diet F and P respectively.</p
EVERY GENUS ONE ALGEBRAICALLY SLICE KNOT IS 1-SOLVABLE
No full textCochran, Orr, and Teichner developed a filtration of the knot concordance group indexed by half integers called the solvable filtration. Its terms are denoted by F-n. It has been shown that F-n/F-n.5 is a very large group for n >= 0. For a generalization to the setting of links the third author showed that F-n.5/Fn+1 is non-trivial. In this paper we provide evidence for knots F-0.5 = F-1. In particular we prove that every genus 1 algebraically slice knot is 1-solvable.
