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
Measurement of the ratio of branching fractions B(B0→K∗0γ )/B(B0s→φγ ) and the directCP asymmetry inB 0→K∗0γ
No full textThe ratio of branching fractions of the radiative B decays B0→K⁎0γ and B0s→ϕγ has been measured using an integrated luminosity of 1.0 fb−1 of pp collision data collected by the LHCb experiment at a centre-of-mass energy of s√=7TeV. The value obtained is
B(B0→K⁎0γ)B(B0s→ϕγ)=1.23±0.06(stat.)±0.04(syst.)±0.10(fs/fd),
where the first uncertainty is statistical, the second is the experimental systematic uncertainty and the third is associated with the ratio of fragmentation fractions fs/fd. Using the world average value for B(B0→K⁎0γ), the branching fraction B(B0s→ϕγ) is measured to be (3.5±0.4)×10−5.
The direct CP asymmetry in B0→K⁎0γ decays has also been measured with the same data and found to be
ACP(B0→K⁎0γ)=(0.8±1.7(stat.)±0.9(syst.))%.
Both measurements are the most precise to date and are in agreement with the previous experimental results and theoretical expectations
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
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
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
Measurement of b-hadron masses
No full textMeasurements of b-hadron masses are performed with the exclusive decay modes B +→J/ψK +, B 0→J/ψK +, B0→J/ψKS0, Bs0→J/ψφ and Λb0→J/ψΛ using an integrated luminosity of 35pb -1 collected in pp collisions at a centre-of-mass energy of 7 TeV by the LHCb experiment. The momentum scale is calibrated with J/ψ→μ +μ - decays and verified to be known to a relative precision of 2 ×10 -4 using other two-body decays. The results are more precise than previous measurements, particularly in the case of the Bs0 and Λb0 masses

Measurement of the CKM angle gamma from a combination of B->Dh analyses
No full textA combination of three LHCb measurements of the CKM angle gamma is presented. The decays B->DK and B->Dpi are used, where D denotes an admixture of D0 and D0-bar mesons, decaying into K+K-, pi+pi-, K+-pi-+, K+-pi-+pi+-pi-+, KSpi+pi-, or KSK+K- final states. All measurements use a dataset corresponding to 1.0 fb-1 of integrated luminosity. Combining results from B->DK decays alone a best-fit value of gamma = 72.0 deg is found, and confidence intervals are set gamma in [56.4,86.7] deg at 68% CL, gamma in [42.6,99.6] deg at 95% CL. The best-fit value of gamma found from a combination of results from B->Dpi decays alone, is gamma = 18.9 deg, and the confidence intervals gamma in [7.4,99.2] deg or [167.9,176.4] deg at 68% CL, are set, without constraint at 95% CL. The combination of results from B->DK and B->Dpi decays gives a best-fit value of gamma = 72.6 deg and the confidence intervals gamma in [55.4,82.3] deg at 68% CL, gamma in [40.2,92.7] deg at 95% CL are set. All values are expressed modulo 180 deg, and are obtained taking into account the effect of D0-D0bar mixing
