Measuring impact of academic research in computer and information science on society
Academic research in computer & information science (CIS) has
contributed immensely to all aspects of society. As academic
research today is substantially supported by various government
sources, recent political changes have created ambivalence
amongst academics about the future of research funding. With
uncertainty looming, it is important to develop a framework to
extract and measure the information relating to impact of CIS
research on society to justify public funding, and demonstrate the
actual contribution and impact of CIS research outside academia.
A new method combining discourse analysis and text mining of a
collection of over 1000 pages of impact case study documents
written in free-text format for the Research Excellence
Framework (REF) 2014 was developed in order to identify the
most commonly used categories or headings for reporting impact
of CIS research by UK Universities (UKU). According to the
research reported in REF2014, UKU acquired 83 patents in
various areas of CIS, created 64 spin-offs, generated £857.5
million in different financial forms, created substantial
employment, reached over 6 billion users worldwide and has
helped save over £1 billion Pounds due to improved processes etc.

Doppler Tomography of Dwarf Nova IY UMa during Quiescence
Quiescent Doppler tomography of the newly discovered deeply-eclipsing SU UMa
system IY UMa reveals properties of the region where the accretion stream from
the donor impacts the edge of the disc. A very strong bright spot is produced
and the Keplerian disc emission in the impact region is disrupted or obscured.
The differing properties of Halpha, Hbeta and He I emission will allow physical
parameters of the converging flow region to be studied.Comment: 6 pages, 5 figures. To appear in Proceedings of Astro-Tomography

PREFERENTIAL TRADE OF AGRICULTURAL COMMODITIES IN THE CARIBBEAN BASIN
Preferential agricultural trade under the Caribbean Basin Initiative has been beneficial to participating countries, particularly for differentiated goods. Goods that have not performed well were either subject to policy changes, eroding preferences and deteriorating market trends or structural changes that diminished CBI exports.International Relations/Trade,

Effect of side chains on the dielectric properties of alkyl esters derived from palm kernel oil
Alkyl ester derivatives were synthesized from laboratory purified palm kernel oil. The steps in the synthesis involved transesterification of palm kernel oil to produce a methyl ester, followed by epoxidation and then the grafting of side chains by esterification with propionic and butyric anhydride. The dielectric and thermal properties of the ester derivatives were analyzed and compared with the methyl ester. The melting point of the ester derivatives were found to reduce with side chain attachment and antioxidant improved its thermal stability. The dielectric loss was dominated by mobile charged particles and the chemical modification appeared to increase the rate at which electric double layer was formed at the electrode-liquid interface. The esters possessed excellent breakdown strengths suggesting that the processing to optimize their physical properties did not have a negative influence on their electrical breakdown strength. This product may prove useful as an insulation fluid in Electrical Power Transformers
On dynamical gluon mass generation
The effective gluon propagator constructed with the pinch technique is
governed by a Schwinger-Dyson equation with special structure and gauge
properties, that can be deduced from the correspondence with the background
field method. Most importantly the non-perturbative gluon self-energy is
transverse order-by-order in the dressed loop expansion, and separately for
gluonic and ghost contributions, a property which allows for a meanigfull
truncation. A linearized version of the truncated Schwinger-Dyson equation is
derived, using a vertex that satisfies the required Ward identity and contains
massless poles. The resulting integral equation, subject to a properly
regularized constraint, is solved numerically, and the main features of the
solutions are briefly discussed.Comment: Special Article - QNP2006: 4th International Conference on Quarks and
