Dr. Jekyll and Mr. Hyde: The Complicated Identity of the Brussels International Festival of Fantastic Films
The Brussels International Festival of Fantastic Films (BIFFF) is a genre festival specializing in thriller, horror, science fiction and fantasy films. Started in 1983, with an initial audience of 32,650 for a festival of 60 films, by its most recent run in April 2015, 64,400 tickets were sold for a showing of 108 films (BIFFF Presentation 4-5; âFestival 2015â 2015). The almost doubling in audience attendance over the course of the BIFFFâs 33 year run emphasizes the manner in which the festivalâs identity has become oriented towards a specific and passionate audience. Interestingly, as the festivalâs audience engagement has increased, so too has its international identity, creating a unique place for the Brussels International Festival of Fantastic Film in the global festival sphere. On a local level Brussels International Festival of Fantastic Film can be seen as a cult event, differentiated from major festivals through its film selection and fandom focus; however, the festivalâs proliferation of prizes and international networking demonstrates that even a genre festival is subject to the logic of proliferation described in James Englishâs landmark work The Economy of Prestige
Origins of NASA names
Names are selected for NASA spaceflight projects and programs from various sources. Some have their foundations in mythology and astrology or legend and folklore. Some have historic connotations; others are based on a description of their mission, often resulting in an acronym. Included are names of launch vehicles, spacecraft, manned spaceflight programs, sounding rockets, and NASA field installations. This study is limited to names of approved projects through 1974; it does not include names of numerous projects which have been or are being studied or projects that were canceled or postponed before reaching actual flight
The orbit rigidity matrix of a symmetric framework
A number of recent papers have studied when symmetry causes frameworks on a
graph to become infinitesimally flexible, or stressed, and when it has no
impact. A number of other recent papers have studied special classes of
frameworks on generically rigid graphs which are finite mechanisms. Here we
introduce a new tool, the orbit matrix, which connects these two areas and
provides a matrix representation for fully symmetric infinitesimal flexes, and
fully symmetric stresses of symmetric frameworks. The orbit matrix is a true
analog of the standard rigidity matrix for general frameworks, and its analysis
gives important insights into questions about the flexibility and rigidity of
classes of symmetric frameworks, in all dimensions.
With this narrower focus on fully symmetric infinitesimal motions, comes the
power to predict symmetry-preserving finite mechanisms - giving a simplified
analysis which covers a wide range of the known mechanisms, and generalizes the
classes of known mechanisms. This initial exploration of the properties of the
orbit matrix also opens up a number of new questions and possible extensions of
the previous results, including transfer of symmetry based results from
Euclidean space to spherical, hyperbolic, and some other metrics with shared
symmetry groups and underlying projective geometry.Comment: 41 pages, 12 figure
Allelic variation in the canine Cox-2 promoter causes hypermethylation of the canine Cox-2 promoter in clinical cases of renal dysplasia
BACKGROUND: Novel allelic variants in the promoter of the canine cyclooxygenase-2 (Cox-2) gene are associated with renal dysplasia (RD). These variants consist of either deletions of putative SP1 transcription factor-binding sites or insertions of tandem repeats of SP1-binding sites located in the CpG island just upstream of the ATG translation initiation site. The canine Cox-2 gene was studied because Cox-2-deficient mice have renal abnormalities and a pathology that is strikingly similar to RD in dogs. FINDINGS: The allelic variants were associated with hypermethylation of the Cox-2 promoter only in clinical cases of RD. The wild-type allele was never methylated, even in clinical cases that were heterozygous for a mutant allele. In cases that were biopsy-negative, the promoter remained unmethylated, regardless of the genotype. Methylated DNA was found in DNA from various adult tissues of dogs with clinical RD. CONCLUSIONS: The mechanism of action of the allelic variation in the canine Cox-2 promoter most likely involves variation in the extent of epigenetic downregulation of this gene. This epigenetic downregulation must have occurred early in development because methylated Cox-2 promoter DNA sequences are found in various adult tissues
A note on heat and mass transfer from a sphere in Stokes\ud flow at low PĂ©clet number
We consider the low PĂ©clet number, Pe âȘ 1, asymptotic solution for steady-state heat and mass transfer from a sphere immersed in Stokes flow with a Robin boundary condition on its surface, representing Newton cooling or a first-order chemical reaction. The application of van Dykeâs rule up to terms of O(Pe3) shows that the O(Pe3 log Pe) terms in the expression for the average Nusselt/Sherwood number are double those previously derived in the literature. Inclusion of the O(Pe3) terms is shown to increase significantly the range of validity of the expansion
Britain Says NO: Voting in the AV Ballot Referendum
The purpose of this paper is to explain why voters made the choices that they did in Britains Alternative Vote (AV) referendum on 5 May 2011. The paper utilises four alternative theoretical models to analyse individual voting behaviour. They are described as the cost-benefit, cognitive engagement, heuristics and mobilisation models. The explanatory power of these models is investigated using a large survey data set gathered in the AV referendum study conducted in conjunction with the British Election Study. Multivariate analyses show that all four models contribute to explaining why some people voted in favour of electoral reform, with the cost-benefit model exhibiting particularly strong effects. The conclusion discusses public reactions to the referendum and possible implications of the decisive rejection of electoral reform after a campaign characterised by disaffection and disengagement. © 2011 The Author Published by Oxford University Press on behalf of the Hansard Society.

Unsung heroes: Constituency election agents in British general elections
Despite their central role in the electoral process, constituency agents have been largely overlooked by political scientists and this article seeks to rectify the omission. It sketches the origins and development of the role of agent from the late 19th century and suggests that a serious rethink of the role took place in the 1990s. Survey-based evidence about the social characteristics of agents is presented confirming that they are largely middle-aged, middle-class, well-educated men. They are also becoming more experienced, offer realistic assessments of the impact of constituency campaigning and, arguably, many take a long-term view of how their party's support can be maximised
