Body, time, and the others: African-American anthropology and the rewriting of ethnographic conventions in the ethnographies by Zora Neale Hurston and Katherine Dunham
No full textThis thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This research looks at the ethnographies Mules and Men (1935) and Tell My Horse: Voodoo and Life in Haiti and Jamaica (1938) by Zora Neale Hurston focusing on representations of Time and the anthropologist’s body. Hurston was an African-American anthropologist, folklorist, and novelist who conducted research particularly between the end of the 1920s and the mid-1930s. At first, her fieldwork and writings dealt with African-American communities in Florida and Hoodoo practice in Louisiana, but she consequently expanded her field of anthropological interests to Jamaica and Haiti, which she visited between 1936 and 1937. The temporal and bodily factors in Hurston’s works are taken into consideration as coordinates of differentiation between the ethnographer and the objects of her research. In her ethnographies, the representation of the anthropologist’s body is analysed as an attempt at reducing temporal distance in ethnographical writings paralleled by the performative experience of fieldwork exemplified by Hurston’s storytelling: body, voice, and the dialogic representation of fieldwork relationships do not guarantee a portrayal of the anthropological subject on more egalitarian terms, but cast light on the influence of the anthropologist both in the practice and writing of ethnography. These elements are analysed in reference to the visualistic tradition of American anthropology as ways of organising difference and ascribing the anthropological ‘Others’ to a temporal frame characterised by bodily and cultural features perceived as ‘primitive’ and, therefore, distant from modernity. Representations and definitions of ‘primitiveness’ and ‘modernity’ not only shaped both twentieth-century American anthropology and the modernist arts (Harlem Renaissance), but also were pivotal for the creation of a modern African-American identity in its relation to African history and other black people involved in the African diaspora. In the same years in which Hurston visited Jamaica and Haiti, another African-American woman anthropologist and dancer, Katherine Dunham, conducted fieldwork in the Caribbean and started to look at it as a source of inspiration for the emerging African-American dance as recorded in her ethnographical and autobiographical account Island Possessed (1969). Therefore, Hurston’s and Dunham’s representations of Haiti are examined as points of intersection for the different discourses which both widened and complicated their understanding of what being ‘African’ and ‘American’ could mean.Isambard Research Scholarship from Brunel University and grant from Allan & Nesta Ferguson Charitable Trust
Perceived justice in email service recovery
No full textThis study adds to the limited research of service recovery in an online environment, drawing on data from Australia. It is perhaps the first non-US study of email service recovery as well as the first to apply a theoretical perspective - perceived justice - to email service recovery. The results of three annual studies resemble US results and support extending perceived justice to service recovery via email. The distributive elements of replying and offering compensation, the procedural element of answering completely, and the interactional element of thanking the customer showed significant positive relationships with customer satisfaction, positive word-of-mouth and repurchase intent. Perhaps most importantly for practitioners, the results of a stepwise regression showed that incorporating the simple phrase "thank-you" in the email reply was a strong predictor of successful email service recovery. Finally, this study found that response time might be less critical than previously thought
Historic bridge photographs : the Lahey collection
No full textRomeo Watkins Lahey (1887-1968) was a distinguished Queensland engineer. He graduated in engineering from the University of Sydney in 1914 and served in World War I from 1915 to 1918 with The Royal Australian Engineers. Following the war, he accepted an offer to remain for a period in England and studied town planning at the University of London. He visited Europe and collected a remarkable set of historic bridge photographs. In the course of this visit, he met Paul Sejourne, a distinguished French bridge engineer, the designer of at Ieast one of the bridges (at Fontpedrouse, pages 25-27) included in this set. When Lahey died, his wife Sybil and daughter Ann took steps to give this remarkable set of 58 historic bridge photographs to The University of Queensland. More recently, Lahey's daughters Ann Neale and Alison Drake have given a set of lantern plates collected by their father, many of which also have photographs of bridges. This volume is divided into three parts: (a) a biography of Romeo Watkins Lahey, written by his daughter, Ann Neale; (b) copies of the original set of 58 bridge photographs, and (c) copies taken from 32 lantern plates. To these have been added captions. Many of the original photographs carried titles; where these are available they have been printed in italics. Further work has been done to identify bridges and where possible the captions include the completion date, major dimensions, locations, and references to published works. Plates 8.1-10 are copies of drawings used as Figures in a book. These drawings have not been copied and the source has not been identified. Two lists of photographs and plates are included - the first in the order of the original collections and a second with bridges listed in the order of material, structural form and date. The collection is of remarkable value to any bridge historian, and is recommended for study by students
Genetic structure and association mapping of adaptive and selective traits in the east Texas loblolly pine (Pinus taeda L.) breeding populations
No full textFirst-generation selection (FGS) and second-generation selection (SGS) breeding populations of loblolly pine from east Texas were studied to estimate the genetic diversity, population structure, linkage disequilibrium (LD), signatures of selection and association of breeding traits with a genome-wide panel of 4,264 single nucleotide polymorphisms (SNPs). Relatively high levels of observed (H (o) = 0.178-0.198) and expected (H (e) = 0.180-0.198) heterozygosities were observed in all populations. The amount of inbreeding was very low with many populations exhibiting a slight excess of heterozygotes. The population structure was weak, but F (ST) indicated more pronounced differentiation in the SGS populations. As expected for outcrossing natural populations, the genome-wide LD was low, but marker density was insufficient to deduce the decay rate. Numerous associations were found between various phenotypic traits and SNPs, but only a few remained significant after false positive correction. Signatures of diversifying and balancing selection were found in markers representing important biological functions. These results present the first step in the application of marker-assisted selection (MAS) to the Western Gulf Forest Tree Improvement Program (WGFTIP) for loblolly pine and will contribute to the knowledgebase necessary for genomic selection technology

Anomalous monism and mental causality : on the debate of Donald Davidson’s philosophy of the mental
No full textThe English version of the first chapter of Erwin Rogler and Gerhard Preyer: Materialismus, anomaler Monismus und mentale Kausalität. Zur gegenwärtigen Philosophie des Mentalen bei Donald Davidson und David Lewis (2001) "Anomaler Monismus und Mentale Kausalität. Ein Beitrag zur Debatte über Donald Davidsons Philosophie des Mentalen" is a contribution to the current debates on the philosophy of the mental and mental causality initiated from Donald Davidson's philosophy with his article "Mental Events" (1970). It is the intent of the English version to give a response to the controversy among American, British and Australian philosophers in the context of a global exchange of ideas on problems understanding the mental. Contents 1. Preliminary Remarks 2. The Critique of Property-Epiphenomenalism and Counterarguments (a) The Enlargement of Nomological Reasoning (b) The Counterfactual Analysis (c) Supervenient Causality 3. Are Mental Properties real or unreal (fictive)? Abstract Things and events are fundamental entities in Davidson's ontology. Less distinct is the ontological status of properties, especially of mental types. Despite of some eliminative allusions there are weighty reasons to understand Davidson's philosophy of mind as including intentional realism. With it, the question of mental causality arises. There are two striking solutions to this problem: the epiphenomenalism of mental properties and the downward causation of mental events. Davidson cannot accept either. He claims to justify the mental as supervenient causality in order to thus integrate it into physicalism (his version of monism). But his argument at best proves the explanatory, not the causal relevance of mental properties. For this and for other reasons, Davidson fails the aspired synthesis of a sufficiently strong physicalism and the autonomy of the mental; a project whose realization is anyhow hard to achieve
Activity of the leukotriene pathway in Barrett’s metaplasia and oesophageal adenocarcinoma
No full textOBJECTIVE: Leukotriene (LT) B(4) is a lipid inflammatory mediator implicated in tumorigenesis in animal models of Barrett's oesophagitis, but little is known about the cysteinyl-leukotrienes (LTC(4), LTD(4), LTE(4)), which have distinct inflammatory and tumorigenic actions in other tissues. We recently showed that the terminal enzymes for the synthesis of both LT families are highly expressed in human oesophageal adenocarcinoma (OA) tissues. This study therefore examined the capacity of Barrett's metaplasia (BM) and OA tissues to synthesise LTs in vitro.SUBJECTS AND METHODS: Oesophageal biopsies from patients with BM (n = 14), high-grade dysplasia (n = 2), OA (n = 11), and squamous control tissues (n = 11) were cultured with calcium ionophore A32187 (2 ?M) for 60 min. LTB(4) and cysteinyl-leukotrienes were extracted and measured by specific enzyme immunoassays.RESULTS: Levels of LTB(4) and cysteinyl-leukotrienes were 8.6-fold (P < 0.01) and 2.4-fold (P < 0.02) higher, respectively, in OA tissues than in squamous control tissues, but levels in BM tissues (n = 14) were not altered. Production of the two LT families correlated across all tissue types (r = 0.62, p < 0.00005).CONCLUSIONS: Increased synthesis of LTB(4) and cysteinyl-leukotrienes has not previously been shown in human OA tissue and our results may indicate a role of these lipids in Barrett's disease progression
Conserved ortholog sets in forest trees
No full textPutative single-copy genes and conserved ortholog sets (COS) were identified in model plant species thale cress (Arabidopsis thaliana), rice (Oryza sativa ssp. japonica), and poplar [black cottonwood, Populus trichocarpa (Torr. & Gray ex Brayshaw)] and used to find putative COS in four conifers (the Coniferales order). Using expressed sequence tag sequences, unique transcript sets were assembled in loblolly pine (Pinus taeda L.), white spruce [Picea glauca (Moench) Voss], Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco var. menziesii], and sugi [Cryptomeria japonica (Thunberg ex Linnaeus f.) D. Don]. They were compared with COS sets identified in three model plant species using comparative sequence analysis. Almost half of the single-copy genes in herbaceous species (Arabidopsis and rice) had additional copies and homologs in poplar and conifers. The identified tentative COS sets have many applications in evolutionary genomics studies, phylogenetic analysis, and comparative mapping
Climate-related adaptive genetic variation and population structure in natural stands of Norway spruce in the South-Eastern Alps.
No full textForest trees dominate many Alpine landscapes that are currently exposed to changing climate. Norway spruce is one of the most important conifer species of the Italian Alps, and natural populations are found across steep environmental gradients with large differences in temperature and moisture availability. This study seeks to determine and quantify patterns of genetic diversity in natural populations toward understanding adaptive responses to changing climate. Across the Italian species range, 24 natural stands were sampled with a major focus on the Eastern Italian Alps. Sampled trees were genotyped for 384 selected single nucleotide polymorphisms (SNPs) from 285 genes. A wide array of potential candidate genes was tested for correlation with climatic parameters. To minimize false-positive association between genotype and climate, population structure was investigated. Pairwise F ST estimates between sampled populations ranged between 0.000 and 0.075, with the highest values involving the two disjoint populations, Valdieri, on the western Italian Alps, and Campolino, the most southern population on the Apennines. Despite considerable genetic admixture among populations, both Bayesian and multivariate approach identified four genetic clusters. Selection scans revealed five F ST outliers, and the environmental association analysis detected ten SNPs associated to one or more climatic variables. Overall, 13 potentially adaptive loci were identified, three of which have been reported in a previous study on the same species conducted on a broader geographical scale. In our study, precipitation, more than temperature, was often associated with genotype; therefore, it appears as the most important environmental variable associated with the high sensitivity of Norway spruce to soil water supply. These findings provide relevant information for understanding and quantifying climate change effects on this species and its ability to genetically adap
