Engaging with citizens online: Understanding the role of ePetitioning in local government democracy

This article can be accessed from the link below.According to the Local Democracy, Economic Development and Construction Act introduced in 2009, UK local authorities are expected to implement ―a facility for making petitions in electronic form to the authority‖. Motivated by this arrangement, this paper reflects on the findings of a case study investigation conducted with the Royal Borough of Kingston (one of the first local authorities to implement such a service since 2004). Lessons learnt from the case suggest that ePetitions reveal increased potential to enhance local government democracy, but are also shaped by challenging open implementation issues which can highly influence the initiative’s impact. Our conclusions are developed within the general debate about online public participation or eParticipation and particularly examine the implications for policy makers

The effect of hydrogen on the magnetic properties of FeV superlattice

The electronic and magnetic structures of a hydrogenated and hydrogen free superlattice of 3 iron monolayers and 9 vanadium monolayers are studied using the first principle full-potential augmented-plane-wave method as implemented in WIEN2k package. The volume, the total energy and the magnetic moments of the system are studied versus the hydrogen positions at the octahedral sites within the superlattice and also versus the filling of the vanadium octahedral location by hydrogen atoms. It is found that the hydrogen locations at the interior of vanadium layer are energetically more favourable. The local Fe magnetic moment and the average magnetic moment per supercell are found to increase as the H position moves towards the Fe-V interface. On the other hand, the average magnetic moment per supercell is found to initially decrease up to filling by 3 H atoms and then increases afterwards. To our knowledge, this is the first reporting on the increase in the computed magnetic moment with hydrogenation. These trends of magnetic moments are attributed to the volume changes resulting from hydrogenation and not to electronic hydrogen-metal interaction.Comment: 13 pages, 5 figures and 2 table

Location based modelling for Heritage Mobile Applications

Recent strategies for increasing museum income have heightened the need to motivate visits. Consequently, ICT has been increasingly used in historical locations to educate and entertain visitors. This exploratory study concerns one such museum that is developing its understanding of these technologies through the perspective of visitors as the key stakeholder. It views the significance of historical landscapes’ technologies that reflect the views of visitors. A quantitative study is conducted to explore preferred technologies and the way in which digital media can be presented in a natural environment, as well as how visitors prefer such experiences to be described. To define and assess the technologies in Dorset County Museum and Maiden Castle, data was collected using a survey in both locations. The results identified differences in visitors’ perceptions regarding the importance of technologies in these museum and physical locations. The outcomes of this study can be applied to improve the effectiveness of technology in interlinked heritage landscapes through development of mobile or web prototypes

Comparison of different dietary sources of n-3 polyunsaturated fatty acids on immune response in broiler chickens

The study aims to research the effects of varied dietary sources of n-3 polyunsaturated fatty acids (PUFA) on the immune response in broiler chickens with stress on natural killer (NK) cell activity. Diets supplemented with one of the four sources of n-3 PUFA: linseed oil-, echium oil-, fish oil (FO) or algal biomass-enriched diets at levels of 18, 18, 50 and 15 g/kg fresh weight, were provided for one-d-old male Ross 308 broilers, totaling 340 in number, until they were slaughtered. The analyses included total lipid profile using gas chromatography (GC) for plasma, spleen, thymus, and blood. Additionally, NK cell activity and cell proliferation were investigated for thymocytes and splenocytes. The results indicated that the source of n-3 PUFA had a strong influence on fatty acid composition across all tissues. NK activity was highest in splenocytes and PBMCs from broilers fed linseed oil, followed by those fed algal biomass or echium oil, and lowest for those from broilers fed FO. The proliferative response of lymphocytes from algal biomass-fed chickens tended to be the highest, followed by those fed linseed oil in most cases. Lymphocytes from chickens fed fish oil showed the lowest proliferative response. These results could mean that a docosahexaenoic acid (DHA)-rich algal product might enrich chicken meat with n-3 PUFA without significant damaging effects on chicken immunity

The Relationship between IR Effectiveness Measures and User Satisfaction

This paper presents an experimental study of users assessing the quality of Google web search results. In particular we look at how users' satisfaction correlates with the effectiveness of Google as quantified by IR measures such as precision and the suite of Cumulative Gain measures (CG, DCG, NDCG). Results indicate strong correlation between users' satisfaction, CG and precision, moderate correlation with DCG, with perhaps surprisingly negligible correlation with NDCG. The reasons for the low correlation with NDCG are examined

Users' effectiveness and satisfaction for image retrieval

This paper presents results from an initial user study exploring the relationship between system effectiveness as quantified by traditional measures such as precision and recall, and users’ effectiveness and satisfaction of the results. The tasks involve finding images for recall-based tasks. It was concluded that no direct relationship between system effectiveness and users’ performance could be proven (as shown by previous research). People learn to adapt to a system regardless of its effectiveness. This study recommends that a combination of attributes (e.g. system effectiveness, user performance and satisfaction) is a more effective way to evaluate interactive retrieval systems. Results of this study also reveal that users are more concerned with accuracy than coverage of the search results

Orbital Fluctuation-Induced Triplet Superconductivity : Mechanism of Superconductivity in Sr2RuO4{\rm Sr}_{2}{\rm RuO}_{4}

The mechanism of superconductivity in ${\rm Sr}_{2}{\rm RuO}_{4}$ is studied using a degenerate Hubbard model within the weak coupling theory. When the system approaches the orbital instability which is realized due to increasing the on-site Coulomb interaction between the electrons in the different orbitals, it is shown that the triplet superconductivity appears. This superconducting mechanism is only available in orbitally degenerate systems with multiple Fermi surfaces.Comment: 5 pages, 4 figure
