1. Qualitative risk assessment to support a policy decision on partially eviscerated (effilé) poultry production - James, Christian; Daramola, Bukola; Dudkiewicz, Agnieszka; Purnell, Graham
Partially-eviscerated (also described as effilé, effileé, roped, partly eviscerated, partially drawn, wire drawn or Boston drawn) poultry are produced by removing the intestines from the poultry carcass but leaving the heart, liver, lungs, kidneys, crop, proventriculus and gizzard inside the body cavity (as defined in Regulation (EC) 543/2008). Regulation (EC) 853/2004 allows production of partially-eviscerated poultry, provided it is authorised by the competent authority. The overall aim of this project was to carry out a risk assessment of partially-eviscerated (effilé) poultry production (poultry with the heart, liver, kidneys, crop, proventriculus and gizzard left inside the body cavity) with a view to...

2. Co-operative higher education - Winn, Joss
A keynote talk for the Reimagining the University conference, University of Gloucestershire, 17-18th October 2014.

3. Blackout. What happens when the power goes off? - Matthewman, Steve; Byrd, Hugh
Power generation systems are undoubtedly critical infrastructures. But they are more fragile than is commonly supposed, and there is plenty of evidence they are getting frailer. Recent blackouts are dress rehearsals for a future in which they will appear with greater frequency and greater severity, due to growing uncertainties in supply and growing certainties in demand. Supply is generally taken for granted in western societies. Such is our dependence that our comfort, security, communication systems, transport, health, food supply, businesses and social equity systems struggle when electricity supplies are interrupted. Continuing sophistication and prevalence of electrical appliances only serves to increase...

4. “Bashed be biff by all with ears”: Blue Jam and taboo radio - Dean, Robert; Hand, Richard J.
The primary focus of this chapter is 'Blue Jam' (1997-99), Morris’s three-season ‘ambient’ music/comedy series for BBC Radio. Blue Jam combines music, comedy sketches and monologues with an ambient soundtrack. Within this, the programmes utilize an extraordinarily controlled pace in an exploration of social satire and taboo through abstract, even dream-like, humour. For a radio scholar such as Tim Crook, Morris’s provocative radio work warrants comparison with Orson Welles. Furthermore, it could be argued that Morris’s unique development of the concept of the soundscape in Blue Jam represents an apotheosis of both audio comedy and, paradoxically, the alienating essence of...

5. Tree population studies in low-diversity forests, Guyana. I. Floristic composition and stand structure - Johnston, Mark; Gillman, Michael P.
Studies were undertaken on the floristic composition and stand structure of four 1 hectare plots in the lowland forests of Kurupukari, Guyana. A total of 3897 trees, covering 153 species and 31 plant families were recorded at greater than 5 cm diameter at breast height (dbh). The number of species per hectare ranged from 61 to 84 (>5.0 cm dbh) and 50–71 (>10.0 cm dbh). The total number of trees per hectare varied two-fold between study plots, with 45–50% of the trees within the 5–10 cm size-class. Mean total basal area varied from 32.39–34.63 m2 per 100 m2. The four...

6. Size structure of a dominant neotropical forest tree species, Dicymbe altsonii, in Guyana and some factors reducing seedling leaf area - Isaacs, R.; Gillman, Michael P.; Johnston, M.; Marsh, F.; Wood, B. C.
There has recently been a renewal of interest in the phenomenon of tree species dominance in tropical forests (Condit et al. 1992, Connell & Lowman 1989), following the observations of Richards more than 40 years ago that tropical tree communities often show marked patterns of species dominance (Richards 1952). Thus, whilst a large tree species pool is present in tropical forests there may be factors operating, such as the ectomycorrhizal associations suggested by Connell & Lowman (1989), which facilitate a marked dominance by one or more species, resulting in a reduction of ecological diversity. The quantification of such dominance and the...

7. The variability of orchid population size - Gillman, Michael P.; Dodd, M. E.
Orchid population size has long been believed to be highly variable in time and space. Here we present the first quantitative assessment of the variability of orchid population sizes and compare them with plant and animal population data from the literature. Three measures of temporal variation were used (standard deviation of log10 (population size), Hurst exponent and variance in the intrinsic rate of increase). Eight unfertilized plots of Orchis morio in a factorial fertilizer experiment were assessed for variability in population size over a 26 year period. The Hurst exponent across the eight plots gave measures consistent with pink noise...

8. Assessing the status of poorly known species: lessons from partridges and pheasants of Southeast Asia - McGowan, Philip; Gillman, Michael P.; Dodd, Michael
There is an urgent need to evaluate the status of groups of species for conservation purposes. A species' status is indicated by both its distribution and abundance, and the rate at which these components are changing. This information is scarce for many tropical forest species. We produced four measures of status based on locality and habitat data for 25 partridges and pheasants of Southeast Asia: (1) change in the number of sites from which a species had been recorded; (2) change in the proportion of localities visited from which a species had been recorded; (3) change in the extent of...

9. The effects of disturbance on forest butterflies using two methods of sampling in Trinidad - Wood, Byron; Gillman, Michael P.
The butterfly assemblages of pairs of forest habitats, differing in disturbance level, within the Victoria Mayaro reserve of South-East Trinidad, are described using walk-and-count transects and canopy and understorey fruit traps. The concurrent use of these two butterfly censusing techniques, revealed major but conflicting differences in species accumulation rates under different disturbance conditions. The disturbed evergreen habitat had the significantly highest accumulation rate from walk-and-count data but the significantly lowest from fruit trap data. This reflects the specificity of much of the fruit-feeding guild for closed canopy forest. Disturbed habitats were found to lack a distinct canopy fauna. These results...

10. Detection of delayed density dependence in an orchid population - Gillman, Michael P.; Dodd, M.
1. Annual censuses of Orchis morio (green-winged orchid) flowering spikes have been taken over a 27-year period in a replicated factorial experiment on the effects of fertilizer application. Census data, combined by block or treatment, were used in time-series analyses to test for density dependence. 2. Partial autocorrelation functions revealed the importance of positive correlations at lag 1 and negative correlations at lag 5. Stepwise multiple regressions provided evidence of delayed density dependence, again with a delay of about 5 years, with no evidence of direct (first-order) density dependence. 3. First-order autocorrelations and delayed density dependence were considered in the...

11. The effects of soil fertilizer on amino acids in the floral nectar of corncockle, Agrostemma githago (Caryophyllaceae) - Gardener, Mark C.; Gillman, Michael P.
Plants of the meadow annual Agrostemma githago (Caryophyllaceae) were grown in 1-m2 field plots prepared with three fertilizer treatments as follows: (a) "low", no fertilizer, (b) "medium", 75 g of slow release fertilizer granules, (c) "high", 175 g of granular treatment. After sowing in spring the plants were left until flowering in late summer. Nectar was extracted using 5-μl glass microcapillary tubes. The material was frozen and sampled at a later date. The samples were analysed by high performance liquid chromatography (HPLC) using the AccQtag (Waters Corp.) system. Analysis showed that the total concentration of amino acids increased significantly with...

12. Analyzing variability in nectar amino acids: composition is less variable than concentration - Gardener, Mark C.; Gillman, Michael
Thirty species of flowering plants were analyzed for floral nectar amino acid composition. High-performance liquid chromatography (HPLC) was used in conjunction with AccQtag derivatization to produce accurate and precise data. For any one species, the total concentration of amino acids varies greatly (average coefficient of variation 0.65), but composition is much less variable (average correlation among samples from a single species 0.85). Absolute concentration of individual amino acids is much more variable than the relative abundance (coefficients of variation 0.98 and 0.77, respectively; N = 544, t = 16.98, P < 0.001). When amino acids that occur in only small...

13. Typewriter art: a modern anthology - Tullett, Barrie; Dowling, John; Simpson, Jodi
This book brings together some of the best examples by typewriter artists around the world. As well as key historical work from the Bauhaus, H. N. Werkman and the concrete poets, there is art by contemporary practitioners, both typewriter artists who use the keyboard as a ‘palette’ to create artworks, and artists/typographers using the form as a compositional device.

14. Anempathetic music in Chekhov’s The Cherry Orchard - Dean, Robert
The implications of Chekhov’s counter-intuitive use of the musical score in the third act of the play.

15. Metropolis raised her voice: live digital-Foley & multimedia accompaniment - Dean, Robert; Challis, Benjamin
Since sound was first recorded on a cylinder wrapped in tin foil by Edison in 1877, technology has steadily evolved to allow an ever increasing level of sonic mutability. Gradually, pre-recorded sounds (or 'inputs') which where once fixed could be increasingly manipulated both before and during playback. While early gramophones and tape players afforded the operator very few parameters to experiment within, the development of digital technology transformed sound into a fully plastic medium. As such, sound in the age of digital reproduction has achieved a level of playability more commonly associated with the performance of live music. The sound-operator...

16. Naturalising the artifice: the integration of diegetic theatre music - Dean, Robert
In the late nineteenth and early twentieth century the theatrical traditions and dramatic conventions of the early nineteenth century were challenged by the new modern dramas that would come to dominate the stage in the years that followed. From a musical perspective the changes in the relationship between music and drama that took place during this period are extremely important. The realistic aesthetic could not support the presence of music provided by an offstage orchestra. However, if the non-diegetic underscoring was removed so too were the dramaturgic functions that it completed. One solution to this problem was to use diegetic...

17. Re-writing the social contract: ethical catechism and ‘The Walking Dead’ - Dean, Robert
The setting, exploration, and adaptation of ethical scenarios are processes which lie at the heart of ethical debate. While they are used by philosophers as a means of illustrating key concepts, the conflicts around which they are positioned are charged with a powerful dramatic currency that has been frequently explored and exploited across all forms of narrative media. When these scenarios are set against a post-apocalyptic backdrop the usual considerations that inform moral maxims are inevitably and intentionally re-orientated. This paper will focus on the American TV drama series 'The Walking Dead' (2010) which takes place after a zombie apocalypse and...

18. Diegetic musical motifs in Ibsen’s A Doll’s House and John Gabriel Borkman - Dean, Robert
The music used to accompany a drama can be divided into two main categories: ‘Non-Diegetic Music’ and ‘Diegetic Music.’ These two terms draw a distinction between music which is presented as existing within the storyworld (diegetic) and that which emanates from an external position (non-diegetic). However, neither of these designations refers to a specific technique, rather they are the titles of two different categories into which specific aural applications can be divided. This paper focuses on a form of aural accompaniment that will be referred to as ‘diegetic musical motifs.’ Both diegetic and non-diegetic musical motifs are used to complete...

19. Exergy and the city: the technology and sociology of power (failure) - Byrd, Hugh; Matthewman, Steve
Blackouts—the total loss of electrical power—serve as a reminder of how dependent the modern world and particularly urban areas have become on electricity and the appliances it powers. To understand them we consider the critical nature of electrical infrastructure. In order to provide general patterns from specific cases, a large number of blackouts have been analyzed. Irrespective of cause, they display similar effects. These include measurable economic losses and less easily quantified social costs. We discuss financial damage, food safety, crime, transport, and problems caused by diesel generators. This is more than just a record of past failures; blackouts are...

20. Conceptualization and measurement of dimensionality of place attachment - Chen, Ning (Chris); Dwyer, Larry; Firth, Tracey
To extend the discussion and application of place attachment to tourism-relevant contexts, this article proposes two neglected dimensions: place memory and place expectation. Combining these dimensions, a six-dimension construct of place attachment is tested using confirmatory factor analysis and found to be a good fit for data collected from two places: Sydney, Australia and Shanghai, China. The new dimensionality includes an individual's past experience and future expectations of his/her attachment to a place, and thus has a potential to interpret one's attachment to a place based on a shorter term stay. The implications of the study for researchers and destination...
