Media Heritage and Memory in the Museum: Managing Dennis Potter’s Legacy in the Forest of Dean
No full textThis research explores the ways in which Dennis Potter (1935-1994) is made inheritable to audiences through a rural Heritage Lottery Funded project. With the sale of the written Potter Archive to the Dean Heritage Centre, Gloucestershire, in 2010, this study explores in great detail the processes enacted to interpret the Potter Archive as cultural (television) heritage. Through a creative and innovative research design which utilises autoethnography, inventive qualitative methods and a level of quantitative analysis, this study examines the ways in which Potter is made intelligible to past television audiences, project members and collaborators, local people, and the casual tourist within the heritage environment.
A unique and irreproducible study, this interdisciplinary research sits as a contribution to an emerging field that is located at the interface between Memory studies and Museum Studies and explores the way various forms of mediation are connected to these fields. Inherently at stake in this research is the valorisation of television as heritage, as Potter remains well within living memory. Through proximate and intimate connections to this multifaceted heritage project this work represents one of the first interventions to explore turning television into heritage at a local level drawing together the macro level of cultural policy with the micro level of enacting that policy.
In asking how Dennis Potter’s legacy is managed in the Forest of Dean heritage environment, this thesis explores the ways Potter’s legacy is mediated, how television heritage is consumed and made meaningful (or struggles for meaning) in the museum space, how a writer’s legacy is interpreted by heritage professionals, volunteers, past television audiences and museum visitors, and how television as heritage is consumed online. This thesis makes visible the underlying mechanisms by which the Dennis Potter Archive is (or might yet become) articulated as television heritage, through examining the core managerial, interpretive and memorial processes involved in this high stakes, multi-partner project
Yeast metabolism in fresh and frozen dough : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Food Technology at Massey University, Palmerston North, New Zealand
No full textAuthor also known as SM LovedayFresh bakery products have a very short shelf life, which limits the extent to which manufacturing can be centralised. Frozen doughs are relatively stable and can be manufactured in large volumes, distributed and baked on-demand at the point of sale or consumption. With appropriate formulation and processing a shelf life of several months can be achieved.Shelf life is limited by a decline in proofing rate after thawing, which is attributed to a) the dough losing its ability to retain gas and b) insufficient gas production, i.e. yeast activity. The loss of shelf life is accelerated by delays between mixing and freezing, which allow yeast cells the chance to ferment carbohydrates.This work examined the reasons for insufficient gas production after thawing frozen dough and the effect of pre-freezing fermentation on shelf life. Literature data on yeast metabolite dynamics in fermenting dough were incomplete. In particular there were few data on the accumulation of ethanol, a major fermentation end product which can be injurious to yeast.Doughs were prepared in a domestic breadmaker using compressed yeast from a local manufacturer and analysed for glucose, fructose, sucrose, maltose and ethanol. Gas production after thawing declined within 48 hours of frozen storage. This was accelerated by 30 or 90 minutes of fermentation at 30;C prior to freezing.Sucrose was rapidly hydrolysed and yeast consumed glucose in preference to fructose. Maltose was not consumed while other sugars remained. Ethanol, accumulated from consumption of glucose and fructose, was produced in approximately equal amounts to CO2, indicating that yeast cells metabolised reductively.Glucose uptake in fermenting dough followed simple hyperbolic kinetics and fructose uptake was competitively inhibited by glucose. Mathematical modelling indicated that diffusion of sugars and ethanol in dough occurred quickly enough to eliminate solute gradients brought about by yeast metabolism
7-Deaza cyclic adenosine 5′-diphosphate ribose: first example of a Ca2+-mobilizing partial agonist related to cyclic adenosine 5′-diphosphate ribose
No full textBackground: Cyclic adenosine 5′-diphosphate ribose (cADPR), a naturally occurring metabolite of nicotinamide adenine dinucleotide (NAD+), mobilizes Ca2+ from non-mitochondria' stores in a variety of mammalian and invertebrate tissues. It has been shown that cADPR activates ryanodine-sensitive Ca2+-release channels, working independently of inositol 1,4,5-trisphosphate (IP3) to mobilize intracellular Ca2+ stores. In some systems, cADPR has been shown to be more potent than IP3. The chemo-enzymatic synthesis of structurally modified analogues of cADPR can provide pharmacological tools for probing this new Ca2+-signaling pathway. In this work, we describe the synthesis and evaluation of a structural mimic of cADPR with different Ca2+-releasing properties.Results: 7-Deaza cyclic adenosine 5′-diphosphate ribose (7-deaza cADPR), a novel cADPR analogue modified in the purine ring, was synthesized and its ability to release Ca2+ from non-mitochondria' pools in homogenates made from sea urchin eggs was investigated. 7-Deaza cADPR was more effective in releasing Ca2+ than cADPR, but it only released approximately 66% of the Ca2+ released by a maximal concentration of cADPR. It was also more resistant to hydrolysis than cADPR. If we administered increasing concentrations of 7-deaza cADPR at the same time as a maximal concentration of cADPR, the induction of Ca2+ release by cADPR was antagonized.Conclusions: 7-Deaza cADPR has a Ca2+-release profile consistent with that of a partial agonist, and it is the first reported example of such a compound to act at the cADPR receptor. The imidazole ring of cADPR is clearly important in stimulating the Ca2+-release machinery, and the present results demonstrate that structural modification of a site other than position 8 of the purine ring can affect the efficacy of Ca2+ release. 7-Deaza cADPR represents a significant step forwards in designing modulators of the cADPR signaling pathway
Highly enantioselective synthesis of alkylpyridine derivatives through a Michael/Michael/Aldol cascade reaction
No full textA method for the synthesis of pyridine derivativesbased on a triple cascade reaction catalyzed by chiral secondaryamines was developed. The resulting cyclohexenes (three C–C bonds were formed) were obtained in good yields with good diastereoselectivities and excellent enantioselectivities

Recall of random and distorted positions: Implications for the theory of expertise.
No full textThis paper explores the question, important to the theory of expert performance, of the nature and number of chunks that chess experts hold in memory. It examines how memory contents determine players' abilities to reconstruct (a) positions from games, (b) positions distorted in various ways and (c) and random positions. Comparison of a computer simulation with a human experiment supports the usual estimate that chess Masters store some 50,000 chunks in memory. The observed impairment of recall when positions are modified by mirror image reflection, implies that each chunk represents a specific pattern of pieces in a specific location. A good account of the results of the experiments is given by the template theory proposed by Gobet and Simon (in press) as an extension of Chase and Simon's (1973a) initial chunking proposal, and in agreement with other recent proposals for modification of the chunking theory (Richman, Staszewski & Simon, 1995) as applied to various recall tasks
Jingoism, Public Opinion, and the New Imperialism:Newspapers and imperial rivalries at the fin de siècle
No full textThis essay analyses late-Victorian understandings of the relationship between the press, imperial diplomacy, and popular enthusiasm for empire, and examines how newspapers explained their own role in the imperial rivalries of the 1890s. During imperial disputes between Britain and France (particularly the Fashoda crisis) and between Britain and the United States (the Venezuela boundary dispute) contemporaries claimed that self-interested ‘jingo’ elements of the political elite had sought to foment conflict by manipulating ‘public opinion’, but had been defeated by statesmen (who had used the press for legitimate diplomatic purposes) and by ‘the people’ (who were averse to war). This contrasted with contemporary comments about the role played by the press in provoking wars between the United States and Spain and between Britain and the Transvaal: both the press and the people seemed to succumb to an irrational popular ‘jingoism’, and to sweep statesmen along in their wake. However, this essay argues that these contemporary verdicts about the role of newspapers in focusing popular imperialism have been too easily accepted by historians. During the imperial rivalries of the 1890s the press played an important role as a medium of transnational communication, but did not push statesmen into expansionism
