Analogue Methods in Palaeoecology: Using the analogue Package
No full textPalaeoecology is an important branch of ecology that uses the subfossil remains of organisms preserved in lake, ocean and bog sediments to inform on changes in ecosystems and the environment through time. The analogue package contains functions to perform modern analogue technique (MAT) transfer functions, which can be used to predict past changes in the environment, such as climate or lake-water pH from species data. A related technique is that of analogue matching, which is concerned with identifying modern sites that are floristically and faunistically similar to fossil samples. These techniques, and others, are increasingly being used to inform public policy on environmental pollution and conservation practices. These methods and other functionality in analogue are illustrated using the Surface Waters Acidification Project diatom:pH training set and diatom counts on samples of a sediment core from the Round Loch of Glenhead, Galloway, Scotland. The paper is aimed at palaeoecologists who are familiar with the techniques described but not with R.
Kanter Revisited: Gender, Power and (In)visibility
No full textThis paper revisits Kanter's (1977) seminal work Men and Women of the Corporation, rereading her account of numerical advantage and disadvantage through a poststructuralist lens which exposes hidden dimensions of gendered power. This lens is captured in the ‘(In)visibility Vortex’ (Lewis and Simpson, 2010) which highlights struggles and tensions around the norm through processes of preservation and concealment within the norm as well as dynamics of revealing, exposure and disappearance as features of the margins. The study draws on developments in feminist theorizing, specially around visibility, invisibility and power, to facilitate this rereading. In so doing, the author demonstrate that while Kanter retreated from explanations based on the gendering of organizations or from recognition of gendered power, these dynamics can be identified in her text. The authors suggest that rereading classic texts can surface dimensions of organizations that have contemporary significance and can inform future research

Spaces of contestation: the everyday experiences of ten African migrants in Cape Town
No full textIncludes bibliographical references.Xenophobia in South Africa is so overt that it has take a covert form. The 'xenocide' events that took place in 2008 were called xenophobic acts. It is the recurrent denialism of xenophobia on an everyday basis that this project has explored through the narrative accounts of ten African migrants in Cape Town. The lived everyday experiences of ten African migrants have brought forward the central argument of this thesis. From the data, it is evident that as a reponse to everyday pressures of prejudices and xenophobia in social and physical spaces, African migrants have developed mutable, unsettled and vagrant identities in order to cope with everyday low level violence. This argument emerged as four key stressors have been identified as the components of a more substantial explanation of xenophobia in South Africa. The four key components are: the enforcement of identity (national and group), the demarcation of spaces of belonging, the experiences of economic insecurity, and lastly a 'culture of violence' in South Africa. This thesis argues that these four stressors are the result of an on-going active process of xenophobic attitudes

Player agency in interactive narrative: audience, actor & author
No full textThe question motivating this review paper is, how can
computer-based interactive narrative be used as a constructivist learn-
ing activity? The paper proposes that player agency can be used to
link interactive narrative to learner agency in constructivist theory,
and to classify approaches to interactive narrative. The traditional
question driving research in interactive narrative is, ‘how can an in-
teractive narrative deal with a high degree of player agency, while
maintaining a coherent and well-formed narrative?’ This question
derives from an Aristotelian approach to interactive narrative that,
as the question shows, is inherently antagonistic to player agency.
Within this approach, player agency must be restricted and manip-
ulated to maintain the narrative. Two alternative approaches based
on Brecht’s Epic Theatre and Boal’s Theatre of the Oppressed are
reviewed. If a Boalian approach to interactive narrative is taken the
conflict between narrative and player agency dissolves. The question
that emerges from this approach is quite different from the traditional
question above, and presents a more useful approach to applying in-
teractive narrative as a constructivist learning activity
PhD in Britain, student records 1917-1959, an anonymised sample database
No full textThe database represents the population of 23,510 students admitted for PhD study from 1917 to 1959 at 7 universities of the UK: are Cambridge, Edinburgh, Imperial College, London School of Economics, Manchester, Oxford, and University College London. It is a weighted version of the sample of 9,606 records, as defined on p223 of 'The development of the PhD' by Renate Simpson.
The variables on the database include Sample ID, Sample Weight, University, Faculty, subject, previous University, overseas/home student, age, sex, staff status, full-time/part-time, year first registered, duration of studies, and outcome of studies.
The variables were collected manually from the archives of each University, with systematic sampling.The database was the basis for the second, statistical, part of Renate Simpson's 'The Development of the PhD degree in Britain, 1917-1959 and since: an evolutionary and statistical history in Higher Education', published 2009 by Edwin Mellen Press. The author and book are referred to as RSS and DPhD respectively in documentation. The database contains extracts from student records from seven Universities which included nearly half of all candidates first admitted to doctoral studies during the period 1917-19. These Universities are Cambridge, Edinburgh, Imperial College, London School of Economics, Manchester, Oxford, and University College London. The author died in 2013. The contact for this database is her son and executor of her estate.</p
Variable-energy positron beam study of arsenic diffusion in poly-silicon
No full textThe positron beam technique is shown to be a sensitive indicator of the presence of arsenic within the grain boundaries of poly-silicon. Variable-energy positron beam and secondary-ion mass spectrometry studies have been performed on As+-implanted pre-amorphized Si samples as a function of dose and rapid thermal anneal temperature. Positron trapping within negatively-charged grain boundaries of the recrystallized poly-Si is observed, resulting in a similar to 2% elevation in the Doppler-broadening S lineshape parameter value. Infusion of As+-ions into the grain boundaries passivates the charge and reduces their specific positron-trapping rate.PT: J; CR: AERS GC, 1991, POSITRON BEAMS SOLIE, P162 ASOKAKUMAR P, 1993, NUCL INSTRUM METH B, V74, P89 BOUSETTA A, 1991, NUCL INSTRUM METH B, V55, P565 DANNEFAER S, 1987, PHYS STATUS SOLIDI A, V102, P481 DANNEFAER S, 1989, J APPL PHYS, V66, P3526 DLUBEK G, 1987, PHYS STATUS SOLIDI A, V102, P443 FLYNN CP, 1992, POINT DEFECTS DIFFUS GANIN E, 1989, APPL PHYS LETT, V54, P2127 HAKVOORT RA, 1992, MATER SCI FORUM, V105, P1391 HAKVOORT RA, 1993, THESIS DELFT U TECHN JACKMAN TE, 1989, APPL PHYS A-SOLID, V49, P335 KALISH R, 1984, APPL PHYS LETT, V44, P107 KEINONEN J, 1988, PHYS REV B, V37, P8269 LEO PH, 1981, PHYS STATUS SOLIDI B, V108, K145 LOMBARDO S, 1994, J APPL PHYS, V75, P345 MAKINEN J, 1990, J APPL PHYS, V67, P990 MITCHELL IV, 1991, POSITRON BEAMS SOLID, P121 NASU H, 1987, YOGYO-KYOKAI-SHI, V95, P5 NIELSEN B, 1987, APPL PHYS LETT, V51, P1022 NIELSEN B, 1991, PHYS REV B, V44, P1812 SCHULTZ PJ, 1988, PHYS REV LETT, V61, P187 SCHULTZ PJ, 1988, REV MOD PHYS, V60, P701 SEIDEL TE, 1991, NUCL INSTRUM METH B, V55, P17 SIMPSON PJ, 1991, POSITRON BEAMS SOLID, P125 TAKAI M, 1989, NUCL INSTRUM METH B, V39, P352 TANDBERG E, 1989, CAN J PHYS, V67, P275 VANDERDRIFT A, 1967, PHILIPS RES REP, V22, P267; NR: 27; TC: 0; J9: APPL SURF SCI; PG: 6; GA: QD950Source type: Electronic(1
