The Local and the Distributed in the Sonic Arts

This paper addresses the relationship between local and distributed strategies with reference to two recent participatory sound art projects in Belfast and Rio de Janeiro. The local concern for site and place is discussed and juxtaposed with distributed practices, which,by definition question and extend the very notion of site or locale. I refer to examples from ethnomusicology, anthropology and education in which participative horizontal research methodologies lead to a dynamic articulation of local conditions and allow for a reflection on how technology impacts on social interaction and relationships with place. The works of Samuel Araújo, Georgina Born and Brazilian pedagogue Paulo Freire provide a framework of reference in this context.

Plurality, policy and the local: can hyperlocals fill the gap?

Over the last 15 years, the acceleration in media consolidation has presented a series of policy challenges around diversity of editorial output. While policy debates on national ownership limits and other regulatory interventions are important, developments at the local level are often marginalised. And yet, the direction of travel—towards more consolidation and more deregulation—has arguably been more debilitating for democracy at the local level, where the vast majority of citizens interact with hospitals, schools, transport systems and local councils. The decline of local media—including, in some towns, the wholesale disappearance of local newspapers—leaves citizens starved of information and local institutions less accountable. This article uses an existing conceptual framework for assessing whether and how journalism makes a real-life contribution to democratic life at the local level. Against this normative framework, it then assesses the contribution of hyperlocal media sites to local democracy. We present findings from the most extensive survey of the hyperlocal sector to date, a collaboration with research partners at Cardiff and Birmingham City Universities and Talk About Local, which analysed online questionnaires from over 180 local online media initiatives. Our research offers a unique insight into the funding, operational problems and sustainability of community media sites, and suggests they have the potential to fulfil a vital democratic and civic role. These data inform our conclusions and recommendations for policy initiatives that would invigorate hyperlocal sites and therefore provide a real alternative for otherwise democratically impoverished local communities.

The enchained potential of the local food market

There is a rising demand for local food which traveled only short distances and is marketed directly by the producer. With growing importance of local food also the amount of literature in this field increased. Yet, literature is lacking to examine the challenges and burdens consumers face while trying to purchase local food. Evidence is shown that a gap exists between the intention of consumers who would like to purchase local food and their actual behavior. However, reasons for this gap are only discovered as byproducts of other research objectives. Consequently, this study investigates the specific reasons for the intention-behavior gap of consumers in the local food market. The study makes use of semi-structured face-to-face interviews with rural and urban respondents. The interviews are analyzed by qualitative content analysis based on Elo and Kyngäs (2008). Revealed key drivers for the intention-behavior gap are (1) the lack of awareness where to purchase local food products, (2) the limited reachability of local food producers, (3) the assortment of the local producer in regard to size and composition and (4) the lack in transparency of the prices of local food. Consequently, it is the producers turn to eliminate the revealed barriers by proactively bringing their products closer to the consumer.

Molecular epidemiology of methicillin-resistant Staphylococcus aureus in Switzerland: sampling only invasive isolates does not allow a representative description of the local diversity of clones.

We conducted a molecular study of MRSA isolated in Swiss hospitals, including the first five consecutive isolates recovered from blood cultures and the first ten isolates recovered from other sites in newly identified carriers. Among 73 MRSA isolates, 44 different double locus sequence typing (DLST) types and 32 spa types were observed. Most isolates belonged to the NewYork/Japan, the UK-EMRSA-15, the South German and the Berlin clones. In a country with a low to moderate MRSA incidence, inclusion of non-invasive isolates allowed a more accurate description of the diversity.

Exploring Rac GTPase regulation : the molecular mechanisms governing the DOCK180 and ELMO interaction and the role of this complex in Rac-mediated cell migration

Les protéines DOCK180 et ELMO coopèrent ensemble biochimiquement et génétiquement afin d’activer la GTPase Rac1 lors de plusieurs évènements biologiques. Toutefois, le rôle que jouent ces protéines dans la signalisation par Rac est encore mal compris. Nous émettons l’hypothèse que Dock180 agit comme activateur de Rac, alors que ELMO est requis pour l’intégration de la signalisation de Rac plutôt que son activation per se. Nous postulons que ELMO agit comme signal de localisation intracellulaire afin de restreindre de façon spatio-temporelle la signalisation de Rac en aval de Dock180, et/ou que ELMO agit comme protéine d’échafaudage entre Rac et ses effecteurs pour amplifier la migration cellulaire. Dans l’objectif nº 1, nous démontrons que le domaine PH atypique de ELMO1 est le site d’interaction principal entre cette protéine et DOCK180. De plus, nous démontrons que la liaison entre ELMO et DOCK180 n’est pas nécessaire pour l’activation de Rac, mais est plutôt essentielle pour faciliter la réorganisation du cytosquelette induite par l’activation de Rac en aval de Dock180. Ces résultats impliquent que ELMO pourrait jouer des rôles additionnels dans la signalisation par Rac. Dans l’objectif nº 2, nous avons découvert l’existence d’une homologie structurelle entre ELMO et un module d’autorégulation de la formine Dia1, et avons identifié trois nouveaux domaines dans la protéine ELMO : les domaines RBD, EID et EAD. De façon analogue à Dia1, nous avons découvert que ELMO à l’état basal est autoinhibé grâce à des intéractions intramoléculaires. Nous proposons que l’état d’activation des protéines ELMO est régulé de façon similaire aux formines de la famille Dia, c’est-à-dire grâce à des interactions avec d’autres protéines. Dans l’objectif nº 3, nous identifions un domaine RBD polyvalent chez ELMO. Ce domaine possède une double spécificité pour les GTPases de la famille Rho et Arf. Nous avons découvert que Arl4A agit comme signal de recrutement membranaire pour le module ELMO/DOCK180/Rac. Nos résultats nous permettent de supposer que d’autres GTPases pourraient être impliquées dans l’activation et la localisation de cette voie de signalisation. Nous concluons qu’à l’état basal, ELMO et DOCK180 forment un complexe dans lequel ELMO est dans sa conformation autoinhibée. Bien que le mécanisme d’activation de ELMO ne soit pas encore bien compris, nous avons découvert que, lorsqu’il y a stimulation cellulaire, certaines GTPases liées au GTP peuvent intéragir avec le domaine RBD de ELMO pour relâcher les contacts intramoléculaires et/ou localiser le complexe à la membrane. Ainsi, les GTPases peuvent servir d’ancrage au complexe ELMO/DOCK180 pour assurer une regulation spatiotemporelle adequate de l’activation et de la signalisation de Rac.

Vertically coupled quantum dots in the local spin-density functional theory

We have investigated the structure of double quantum dots vertically coupled at zero magnetic field within local-spin-density functional theory. The dots are identical and have a finite width, and the whole system is axially symmetric. We first discuss the effect of thickness on the addition spectrum of one single dot. Next we describe the structure of coupled dots as a function of the interdot distance for different electron numbers. Addition spectra, Hund's rule, and molecular-type configurations are discussed. It is shown that self-interaction corrections to the density-functional results do not play a very important role in the calculated addition spectra

Water Resource Pollution and Impacts on the local livelihood: A case study of Beas River in Kullu District, India

The rivers are considered as the life line of any country since they make water available for our domestic, industrial and recreational functions. The quality of river water signifies the health status and hygienic aspects of a particular region, but the quality of these life lines is continuously deteriorating due to discharge of sewage, garbage and industrial effluents into them. Thrust on water demand has increased manifolds due to the increased population, therefore tangible efforts to make the water sources free from pollution is catching attention all across the globe. This paper attempts to highlight the trends in water quality change of River Beas, right from Manali to Larji in India. This is an important river in the state of Himachal Pradesh and caters to the need of water for Manali and Kullu townships, besides other surrounding rural areas. The Manali-Larji Beas river stretch is exposed to the flow of sewage, garbage and muck resulting from various project activities, thereby making it vulnerable to pollution. In addition, the influx of thousands of tourists to these towns also contributes to the pollution load by their recreational and other tourist related activities. Pollution of this river has ultimately affected the livelihood of local population in this region. Hence, water quality monitoring was carried out for the said stretch between January, 2010 and January, 2012 at 15 various locations on quarterly basis, right from the upstream of Manali town and up to downstream of Larji dam. Temperature, color, odor, D.O. , pH, BOD, TSS, TC and FC has been the parameters that were studied. This study gives the broad idea about the characteristics of water at locations in the said river stretch, and suggestions for improving water quality and livelihood of local population in this particular domain.

The mapping of the local contributions of Fermi and Coulomb correlation into intracule and extracule density distributions

The contributions of the correlated and uncorrelated components of the electron-pair density to atomic and molecular intracule I(r) and extracule E(R) densities and its Laplacian functions ∇2I(r) and ∇2E(R) are analyzed at the Hartree-Fock (HF) and configuration interaction (CI) levels of theory. The topologies of the uncorrelated components of these functions can be rationalized in terms of the corresponding one-electron densities. In contrast, by analyzing the correlated components of I(r) and E(R), namely, IC(r) and EC(R), the effect of electron Fermi and Coulomb correlation can be assessed at the HF and CI levels of theory. Moreover, the contribution of Coulomb correlation can be isolated by means of difference maps between IC(r) and EC(R) distributions calculated at the two levels of theory. As application examples, the He, Ne, and Ar atomic series, the C2-2, N2, O2+2 molecular series, and the C2H4 molecule have been investigated. For these atoms and molecules, it is found that Fermi correlation accounts for the main characteristics of IC(r) and EC(R), with Coulomb correlation increasing slightly the locality of these functions at the CI level of theory. Furthermore, IC(r), EC(R), and the associated Laplacian functions, reveal the short-ranged nature and high isotropy of Fermi and Coulomb correlation in atoms and molecules
