Grounding Gene Mentions with Respect to Gene Database Identifiers
We describe our submission for task 1B of the BioCreAtIvE competition which is concerned with grounding gene mentions with respect to databases of organism gene identifiers. Several approaches to gene identification, lookup, and disambiguation are presented. Results are presented with two possible baseline systems and a discussion of the source of precision and recall errors as well as an estimate of precision and recall for an organism-specific tagger bootstrapped from gene synonym lists and the task 1B training data. 1
Trust under the prospect theory and quasi-hyperbolic preferences: a field experiment in Vietnam
We conduct a field experiment in Vietnamese villages to explore the effect of the prospect theory and of quasi-hyperbolic time preferences parameters on trust and trustworthiness. We find that risk aversion, loss aversion and present bias do not influence trustorsâ decisions, but a higher time discounting increases the amount sent in the South of Vietnam and probability weighting decreases it in the North. If time discounting and loss aversion do not influence trustworthiness, we show that more risk averse and less present biased trustees return a higher share of their wealth to the trustors. These results suggest that adopting another perspective than the expected utility theory and the exponential discounting approach of time preferences enables to uncover some channels by which risk and intertemporal time preferences influence trusting behavior in societies
Trust and Trustworthiness under the Prospect Theory: A field experiment in Vietnam
We study the influence of risk and time preferences on trust and trustworthiness by conducting a field experiment in Vietnamese villages and by estimating the parameters of the Cumulative Prospect Theory and of quasi-hyperbolic time preferences. We find that while probability sensitivity or risk aversion do not affect trust, loss aversion influences trust indirectly by lowering the expectations of return. Also, more risk averse and less present biased participants are found to be trustworthier. The experience of receiving remittances influences behavior and a longer exposure to a collectivist economy tend to reduce trust and trustworthiness
2. Politique de service et modĂšles d'organisation
Lâun des prĂ©alables de tout projet de service de questions-rĂ©ponses en ligne est la dĂ©finition dâune politique de service, qui influera de maniĂšre plus ou moins directe sur son organisation. LA POLITIQUE DE SERVICE La politique du service dĂ©finit les missions et les objectifs, le pĂ©rimĂštre du service (en termes de publics et de thĂ©matiques), le niveau des rĂ©ponses, les engagements des bibliothĂ©caires et le cas Ă©chĂ©ant du lecteur. Elle dĂ©termine la prestation quâun utilisateur peut attendre. E..
Mode d'emploi
En 1996, dans « CrĂ©er et gĂ©rer un service de rĂ©fĂ©rence », dans cette mĂȘme collection et sous la direction de Corinne Verry-Jolivet, Claire Stra et Jean-Philippe Lamy Ă©voquent encore succinctement le renseignement en ligne. Ă cette Ă©poque les services de rĂ©fĂ©rence virtuels, en plein dĂ©veloppement aux Ătats-Unis, nâont pas encore abordĂ© nos cĂŽtes. Claire Stra, par-delĂ le temps, semble nous passer le relais : « Ce pourrait ĂȘtre lâobjet dâune rĂ©flexion plus approfondie, au sein des bibliothĂšques..
1. Typologie des services de questions-réponses en ligne
Il nây a pas une mais des typologies des services de questions-rĂ©ponses. Je propose donc ces typologies selon le producteur du service (relevant de services documentaires ou non documentaires). Je reviendrai aprĂšs sur les services documentaires, en les classant selon : la nature, gĂ©nĂ©raliste ou spĂ©cialisĂ©e, du service ; le mode et les techniques employĂ©s pour rĂ©pondre Ă la question ; lâouverture du service : restreint/ouvert ; gratuit/payant. Je ferai ensuite une prĂ©sentation des diffĂ©rents t..
The Geographies of Community History Digital Archives in Rural Scotland
The CURIOS (Cultural Repositories and Information Systems) project has been working with community heritage groups to co-produce sustainable solutions for the production of heritage archives in digital form. This process has produced an opportunity for fascinating geographical research into the ways in which community heritage groups produce history from their own perspective. This paper will therefore begin to open up these ongoing processes to consider, through case study examples, the ways in which the production of digital archives alters the geography of community heritage production. A number of community heritage groups have been converting their âanalogueâ collections into âdigitalâ forms and the paper will argue how this significantly alters the positionality of the archive. This will be shown by detailing the ways in which the processes of collection and preservation, conducted by community volunteers, take place. The paper will then move to consider the ways in which this historical material, representative of place, is presented back to a wider audience. In doing this, it will discuss the rationales and processes involved in these practices and how this relates to broader themes of research within geography. Whether for historical research or for theoretical positioning, geographers have, on a number of levels, engaged with archives. Yet, the digital archive has seen little attention especially in terms of thinking through the ways in which digital mediums alter perceptions of space and place
