How appropriate is it to characterise Western universities as institutionally racist?
No full textThe Macpherson Report in 1999 claimed that public organisations, including universities, were characterised by institutional racism. This paper critically examines the concept of institutional racism before using it as a sensitising concept to investigate ethnographically in one university in the UK over a ten-year period. While I was initially sceptical of the analytical utility of the concept of institutional racism, since it seemed to gloss over important conceptual distinctions, the concept ultimately proved revealing in accounting for significant continuities in the approach of universities, including Midshire, to race equality. Throughout the period under discussion, there was a reluctance to identify race equality as a priority and to take corresponding action because of what has been called "the sheer weight of whiteness" (Back 2004, 1). A comparison of Midshire University with Midshire Police reinforced this perception. While it identified contrasts in the occupational cultures of the two organisations, at the same time it pointed to surprising parallels in their approaches to race equality, which stemmed from a taken for granted white norm. Despite this, the concept of institutional racism as defined in the Macpherson report and employed in the Parekhh report fails to capture significant differences between public organisations and changes over time. The author concludes that universities are not appropriately characterised as institutionally racist and are more appropriately conceptualised as pervaded by a white nor

The Highlander
No full textThis thesis explores James Macpherson’s The Highlander (1758) in relation to originality, Scottish identity and historiography. It also situates the Ossianic Collections in the context of Macpherson’s earlier poetical and later historical works. There are three parts to it: a biographical sketch of Macpherson’s early life, the annotated edition of The Highlander, and discursive commentary chapters. By examining The Highlander in detail this thesis questions the emphasis of other Macpherson criticism on the Ossianic Collections, and allows us to see him as a writer who is historically minded, very aware of sources, well versed in established forms of poetry and thoroughly, and positively, British. The Highlander stands out among the corpus of his works not because it can give us insights into the Ossianic Collections, which is its usual function in Macpherson criticism, but because it can help us understand what it is that connects Macpherson’s earlier and later works with the Ossianic Collections: history, Britishness, tradition.
Macpherson’s poetical works are united by a desire to translate Scotland’s factual past into sentimental British poetry. In the Ossianic Collections he does so without particular faithfulness to his sources, but in The Highlander he converts historical sources directly into neo-classic verse. This is where Macpherson’s originality lies: his ability to adapt history. In different styles and genres, and based on different sources, Macpherson’s works are early examples of Scotland’s great literary achievement: historical fiction. Instead of accusing him of forgery or trying to trace his knowledge of Gaelic ballads, this thesis presents Macpherson as a genuine historian who happened to write in a variety of genres
An in vitro stimulation of the effects of chewing sugar-free and sugar-containing chewing gums on pH changes in dental plaque
No full textThe objective of these studies was to simulate the effect of chewing sugar-free and sucrose-containing chewing gums on the return of the pH to neutrality after exposure to sucrose of plaque located on the buccal (BLM) and lingual (LLM) surfaces of the lower molar teeth. In study 1, a 0.5-mm-deep artificial plaque containing Streptococcus oralis cells was exposed to 10% sucrose for one min, and a 0.1-mm-thick film of sucrose-free artificial saliva was then flowed over the plaque surface at the unstimulated salivary film velocities previously found at the BLM and LLM sites. At the time of the pH minimum (pH 4-5), one of three conditions was simulated: (a) a no-gum-chewing control, or chewing for 20 min on either (b) a sugar-free gum or (c) a sucrose-containing gum. The recovery of the plaque pH to resting values was rapid during simulation of chewing a sugar-free gum (SFG), much slower with the no-gum control, and even slower with simulation of chewing a sucrose-containing gum (SCG). The pH recovery was slower with the BLM than the LLM plaque. In study 2, the BLM plaque was exposed to a 2% sucrose solution for 20 min under stimulated salivary conditions, to simulate the consumption of a meal, followed by one of conditions (a), (b), or (c) described above. The pH recovery with simulation of chewing a SCG was faster than with the no-gum control, but much slower than with the SFG simulation
The Chow Motives of Relative Fulton-Macpherson Space
No full textSuppose that is a complex nonsingular projective variety and is a smooth divisor. Compactifications of configuration spaces of distinct and non-distinct points in away from were constructed by the author and B. Kim in "A generalization of Fulton-MacPherson configuration spaces" by using the method of wonderful compactification. In this paper, we give explicit presentations of Chow motives and Chow groups of these configuration spaces
The distribution of saliva and sucrose around the mouth during the use of chewing gum and the implications for the site-specificity of caries and calculus deposition
No full textOver a 20-minute period, subjects expectorated 8 samples of whole saliva (EWS) while chewing gum. Flow rates were calculated, and sucrose was analyzed in these samples as well as in saliva collected on filter paper strips from different tooth surfaces. Salivary film velocity (SFV), based on a 0.1-mm-thick film, was estimated from the clearance half-times of KCl in agarose disks positioned in different regions of the mouth. Salivary flow rate peaked at 5.1 mL/min in the first min but fell to about 1.25 mL/min by the end of the 20 min of gum-chewing. In contrast, flow rate when subjects sucked sour lemon drops averaged about 5.3 mL/min throughout the 20-minute period. The mean salivary sucrose concentration during gum-chewing peaked in the second min at 384 mmol/L (13.1%) but had fallen to 14 mmol/L by the 15-20-minute time interval. The sucrose concentrations on the palatal surfaces of the upper incisors and the facial and lingual surfaces of the lower molars were not significantly different from that in EWS but were much lower on the facial surfaces of the upper incisors and molars, and on the lingual surfaces of the lower incisors. When flow was unstimulated, SFV was 0.8-1.0 mm/min on the facial surfaces of the upper incisors and lower molars but about 5-8 mm/min on the facial surfaces of the upper molars and on the lingual surfaces of the lower incisors and molars
Effects of salivary film velocity on pH changes in an artificial plaque containing Streptococcus oralis, after exposure to sucrose
No full textResults from a computer model suggest that following exposure of dental plaque to sucrose, the rate of clearance of acids from plaque into the overlying salivary film will be greatly retarded at low film velocities. This was investigated with an in vitro technique in which artificial plaque containing S. oralis cells was exposed to 10% sucrose for one min. The pH at the proximal (P) and distal (D) undersurfaces of the plaque (0.5 or 1.5 mm thick) was then monitored during the passage of a 0.1-mm-thick film of a sucrose-free solution over the surface. Over the range of salivary film velocities that have been estimated to occur in vivo (0.8-8 mm/min), lower minimum pH values and increased times for the pH to recover toward neutrality occurred at the lower salivary film velocity. Lower pH values were also reached with the 0.5- than with the 1.5-mm-thick plaque. P/D pH gradients, with a lower pH distally, developed at film velocities of 0.8 and 8 mm/min, and the gradients were much more pronounced at the lower velocity. No P/D pH gradients developed when the film velocity was 86.2 mm/min. Incorporation of dead S. oralis cells into the plaque at percentages up to 57% reduced the extent of the pH fall and prolonged the recovery of the pH toward neutrality. The results support the prediction that, other factors being equal, plaque located in regions of the mouth with low salivary film velocity will achieve pH values lower than those of plaque of identical dimensions and microbial composition located in areas where salivary film velocity is high
Distribution of sucrose around the mouth and its clearance after a sucrose mouthrinse or consumption of three different foods
No full textThe distribution of sucrose in whole saliva and in saliva from seven different regions of the mouth was determined in 10 subjects over the 10-min period following the chewing of a doughnut, sucking on a mint candy, the drinking of orange juice, or use of a 10% sucrose mouthrinse. With all products, the sucrose was distributed non-uniformly, with particularly low concentrations on the lingual surfaces of the lower incisors and the facial surfaces of the upper molars. Clearance was also most rapid from these sites. Since the depth and duration of a Stephan curve in dental plaque is influenced by the sugar concentration to which the plaque is exposed, the results, together with previous results on salivary film velocity in different regions of the mouth, help to provide an explanation for the site-specificity of smooth-surface caries and of supragingival calculus deposition
