Reasons for deploying an e-reader loan service at the UOC Library

The presentation will focus on the reasons for deploying an e-reader loan service at a virtual university library as a part of an e-learning support system to aid user mobility, concentration of documentary and electronic resources, and ICT skills acquisition, using the example of the UOC pilot project and its subsequent consolidation. E-reader devices at the UOC are an extension of the Virtual Campus. They are offered as a tool to aid user mobility, access to documentary and electronic resources, and development of information and IT skills. The e-reader loan service began as a pilot project in 2009 and was consolidated in 2010. The UOC Library piloted the e-reader loan service from October to December 2009. The pilot project was carried out with 15 devices and involved 37 loans. The project was extended into 2010 with the same number of devices and 218 loans (October 2010). In 2011 the e-reader loan service is to involve 190 devices, thus offering an improved service. The reasons for deploying an e-reader loan service at the UOC are the following: a) to offer library users access to the many kinds of learning materials available at the UOC through a single device that facilitates student study and learning; b) to enhance access to and use of the e-book collections subscribed to by the UOC Library; c) to align with UOC strategy on the development of learning materials in multiple formats, and promote e-devices as an extension of the UOC Virtual Campus, and d) to increase UOC Library visibility within and beyond the institution. The presentation will conclude with an analysis of the key issues to be taken into account at a university library: the e-reader market, the unclear business and license model for e-book contents, and the library's role in promoting new reading formats to increase use of e-collections.

Digital inmigrants and digital natives expectation collection in the Andalusian Public Health System Virtual Library: communication with our users

The Andalusian Public Health System Virtual Library (Biblioteca Virtual del Sistema Sanitario Público de Andalucía, BV-SSPA) provides access to health information resources and services to healthcare professionals through its Website. This virtual environment demands higher users’ knowledge in order to satisfy of the need of information of our users, as digital natives as digital immigrants, improving at the same time the communication with all of them. 1. To collect clients' views and expectations according to their nature of digital natives and immigrants. 2. To know our online reputation. A Collecting User Expectation Questionnaire will be built, taking into account the segmentation of the BV-SSPA users’ professional groups of the Andalusian Public Health System. A pilot test will be run to check the survey dimensions and items about practices, attitudes and knowledge of our users. Two Quality Function Deployment (QFD) matrices will enable the BV-SSPA services to be targeted to our digital natives or digital immigrants, according to their nature, finding the best way to satisfy their information needs. We provide feedback on BV-SSPA: users can have the opportunity to post feedback about the site via the 'Contact us' section and comment about their experience. And Web 2.0 is a shop window, providing the opportunity to show the comments; and through time, our online reputation will be built, but the BV-SSPA must manage its own personal branding. Web 2.0 tools are a driver of improvement, because they provide a key source of insight into people's attitudes. Besides, the BV-SSPA digital identity will be analyzed through indicators like major search engine referrals breakdown, top referring sites (non search engines), or top search engine referral phrases, among others. Definition of digital native and digital immigrant profiles of the BV-SSPA, and their difference, will be explained by their expectations. The design of the two QFD matrices will illustrate in just one graph the requirements of both groups for tackling digital abilities and inequalities. The BV-SSPA could deliver information and services through alternative channels. On the other hand, we are developing a strategy to identify, to measure and to manage a digital identity through communication with the user and to find out our online reputation. With the use of different tools from quantitative and qualitative methodology, and the opportunities offered by Web 2.0 tools, the BV-SSPA will know the expectations of their users as a first step to satisfy their necessities. Personalization is pivotal to the success of the Site, delivering tailored content to individuals based on their recorded preferences. The valuable user research can be used during new product development and redesign. Besides positive interaction let us build trust, show authenticity, and foster loyalty: we improve with effort, communication and show.

HypatiaSalud. Institucional Repository for the Andalusian Public Health System, Spain

HypatiaSalud will be the freely accessible institutional repository for the Public Health System in Andalucía, Spain. Open access and new technologies have changed dramatically the environment in which research is being conducted and disseminated. Traditionally University has been the universal research provider, but at present time there are Government Organizations, as Public Health Systems, which are large-producers of research. Meanwhile most universities are running institutional repositories or have plans of setting up institutional repositories in the short-term, there are not many Government Organizations working on that direction. In this sense, HypatiaSalud represents an innovative initiative. Objectives: - Enhancing institutional efficiency, effectiveness and opportunities for knowledge exchange. -Expanding access and greater use of research findings to a much wider range of users increasing the visibility and reputation of Andalusian Public Health System. - Providing the foundation for effective gathering and long-term preservation of research output. Methodology. Phase I: Researching and learning from other institutional repositories. Phase II: Designing and planning the financial, organizational, legal and technical underlying issues. Phase III: Launching the service. Phase IV: Running the service. Outcomes. Bibliometrics: catalog of the research output of the Institution, in order to determine the conditions to include this scientific output in the Institutional Repository: direct deposit, deposit after a period of embargo, or closed access when publisher will not grant permission. Promote a mandate for the deposit of all peer-reviewed final drafts (postprints) for institutional record-keeping purposes. Access to that immediate postprint deposit in HypatiaSalud may be set immediately as ‘Open Access’ if copyright conditions allows; otherwise access can be set as ‘Closed Access’. International Standards application: HypatiaSalud will support OAI-PMH and DRIVER, to allow that central repositories could harvest its content or metadata. Development of human resources strategies in order to foster self-archiving through merit acknowledge and accreditation. Conclusions. It seems likely that setting up an Institutional Repository for the Public Health System in Andalucía would have substantial net benefits in the longer term for the Institution, despite the lag between the costs and realisation of benefits.

Genetic dissection of c-Myc function during mouse organogenesis

Résumé Le gène c-myc est un des oncogènes les plus fréquemment mutés dans les tumeurs humaines. Même si plus de 70 % des cancers humains montrent une dérégulation de c-Myc, les connaissances sur son rôle physiologique pendant le développement, et dans la souris adulte restent très peu connus. Récemment, notre laboratoire a pu montrer que c-Myc contrôle l'équilibre entre le renouvellement et la différenciation des cellules souches hématopoïetiques (CSH) dans la souris adulte. Ceci est probablement dû à lacapacité de c-Myc de contrôler l'entrée et la sortie des CSH de leur niche de la moelle osseuse, en régulant plusieurs molécules d'adhésion, parmi lesquelles la cadhérine-N (Wilson et al., 2004; Wilson and Trumpp, 2006). Des études utilisant un mutant d'inactivation ont demontré que la protéine c-Myc est essentielle pour le développement au delà du jour embryonnaire E9.5. Les embryons c-Myc déficients sont plus petits que la normale et possèdent de nombreux défauts; en particulier ils ne peuvent établir un système hématopoietique embryonnaire primitif (Trumpp et al., 2001). Nous avons récemment découvert que le développement du placenta dépend de la présence de cMyc. Ceci permet de proposer que certains, sinon tous, les défauts embryonnaires puorraient dériver indirectement d'un défaut nutritionnel causé par la défaillance du placenta. Afin de répondre à cette question de manière génétique, nous avons utilisé l'allele conditionel c-mycflox (Trumpp et al., 2001) en combinaison avec l'allele Sox2-Cre (Hayashi et al., 2002). Celui-ci détermine l'expression de la récombinase Cre spécifiquement dans les cellules de l'épiblaste à partir de E6.5, tandis qu'il n'y a pas, ou seulement très peu, d'activité de la récombinase Cre dans les tissus extraembryonnaires.Alnsi, cette stratégie nous permet de générer des embryons sans c-Myc qui se développent en présence d'un compartment extraembryonnaire ou c-Myc est exprimé normalement (Sox2Cre;c-mycflox2) Ces embryons, Sox2Cre;c-mycflox2 se développent et grandissent normalement tout en formant un système vasculaire normal, mais meurent à E11.5 à cause d'un sévère manque de cellules hématopoïetiques. De façon très intéressante, la seule population qui semble être présente en nombre à peu près normal dans ces embryons est celle des précurseurs et des cellules souches. Les cellules qui forment cette population prolifèrent normalement mais ne peuvent pas former des colonies in vitro, ce qui montre que ces cellules ont perdu leur activité de cellules souches. Cependant, lorsque nous avons analysé ces cellules plus en détail en éxaminant l'expression des molécules d'intégrine nous avons découvert que l'integrine ß est sur-éxprimée à la surface des cellules c-Myc déficientes. Ceci pourrait indiquer un mécanisme par lequel c-Myc régule des molécules d'adhésion sur les cellules du sang. En conséquence, en absence de c-Myc, l'adhésion et la migration des cellules du sang de l'AGM (Aorte-Gonade-Mésonéphros) vers le foie de l'embryon, à travers le système vasculaire, est compromise. En outre, nous avons pu montrer que les hépatocytes du foie, qui constitue le site principal de formation des cellules hématopoïetiques pendant le développement, est sévèrement atteint dans des Sox2Cre;c-mycflox2 embryons. Ceci n'est pas du à un défaut propre aux cellules hépatiques qui ont perdu c-Myc, mais résulte plutôt de l'absence de cellules hématopoietïques qui normalement colonisent le foie à ce stade du développement. Ces résultats représentent la première preuve directe que le développement des hépatoblastes est dépendant de signaux provenant des cellules du sang. Summary The myc gene is one of the most frequently mutated oncogenes in human tumors. It is found to be mis-regulated in over 70% of all human cancers. However, our knowledge about its physiological role in mammalian development and adulthood remains limited. Recent work in our laboratory showed that c-Myc controls the balance between hematopoietic stem cell (HSC) self-renewal and differentiation in the adult mouse. This is likely due to the capacity of c-Myc to control entry and exit of HSCs from the bone marrow niche by regulating a number of cell adhesion molecules including N-cadherin (Wilson et al., 2004; Wilson and Trumpp 2006). During development knockout studies showed that c-Myc is required for embryonic development beyond embryonic day (E) 9.5. c-Myc deficient embryos are severely reduced in size and show multiple defects including the failure to establish a primitive hematopoietic system (Trumpp et al., 2001). Importantly, we recentry uncovered that placental development also seems to depend on normal c-Myc function, raising the possibility that some if not all of the embryonic defects observed could be mediated indirectly by a nutrition defect caused by placental failure. To address this possibility genetically, we took advantage of the conditional c-mycflox allele (Trumpp et al., 2001) in combination with the Sox2-Cre allele (Hayashi et al., 2002), in which Cre expression is specifically targeted to all epiblast cells by E6.5, while there is little or no Cre activity inextra-embryonic lineages. Thus, this strategy allows the generation of c-Myc deficient embryos, which develop within a normal c-Myc expressing extra-embryonic compartment (Sox2Cre;c-mycflox2) Such Sox2Cre;c-mycflox2 embryos develop and grow appropriately and form a normal vascular system but die at E11.5 due to a severe lack of blood cells. Interestingly, the only hematopoietic population that seems to be present in almost normal numbers in the embryo is the stem/progenitor cell population. Cells within this populatíon proliferate normal but can not give rise to hematopoietic colonies in vitro showing that functional hematopoietic stem cell (HSC) activity is lost. However, when we analyzed these phenotypic HSCs in more detail and examined integrin expression in mutant stem/progenitor cells, we observed that ß1-integrin is upregulated. This may point to a potential mechanism whereby c-Myc regulates adhesíon molecules on hematopoietic cells and thereby disturbs adhesion and migration from the AGM (aorta-gonads-mesonephros) through the vascular system to the liver. Furthermore, we uncovered that the fetal liver, the main site of hematopoietic expansion at that stage, is severely affected in Sox2Cre;c-mycflox2 embryos and that this is not due to a cell intrinsic defect of c-Myc deficient hepatocytes but rather due to the lack of hematopoietic cells that normally colonize the fetal liver at that stage of development. This provides first direct evidence that hepatoblast development depends on signals derived from blood cells.

Prevalence of and risk factors for biliary carriage of bacteria showing worrisome and unexpected resistance traits.

Data on biliary carriage of bacteria and, specifically, of bacteria with worrisome and unexpected resistance traits (URB) are lacking. A prospective study (April 2010 to December 2011) was performed that included all patients admitted for <48 h for elective laparoscopic cholecystectomy in a Spanish hospital. Bile samples were cultured and epidemiological/clinical data recorded. Logistic regression models (stepwise) were performed using bactobilia or bactobilia by URB as dependent variables. Models (P < 0.001) showing the highest R(2) values were considered. A total of 198 patients (40.4% males; age, 55.3 ± 17.3 years) were included. Bactobilia was found in 44 of them (22.2%). The presence of bactobilia was associated (R(2) Cox, 0.30) with previous biliary endoscopic retrograde cholangiopancreatography (ERCP) (odds ratio [OR], 8.95; 95% confidence interval [CI], 2.96 to 27.06; P < 0.001), previous admission (OR, 2.82; 95% CI, 1.10 to 7.24; P = 0.031), and age (OR, 1.09 per year; 95% CI, 1.05 to 1.12; P < 0.001). Ten out of the 44 (22.7%) patients with bactobilia carried URB: 1 Escherichia coli isolate (CTX-M), 1 Klebsiella pneumoniae isolate (OXA-48), 3 high-level gentamicin-resistant enterococci, 1 vancomycin-resistant Enterococcus isolate, 3 Enterobacter cloacae strains, and 1 imipenem-resistant Pseudomonas aeruginosa strain. Bactobilia by URB (versus those by non-URB) was only associated (R(2) Cox, 0.19) with previous ERCP (OR, 11.11; 95% CI, 1.98 to 62.47; P = 0.006). For analyses of patients with bactobilia by URB versus the remaining patients, previous ERCP (OR, 35.284; 95% CI, 5.320 to 234.016; P < 0.001), previous intake of antibiotics (OR, 7.200; 95% CI, 0.962 to 53.906; P = 0.050), and age (OR, 1.113 per year of age; 95% CI, 1.028 to 1.206; P = 0.009) were associated with bactobilia by URB (R(2) Cox, 0.19; P < 0.001). Previous antibiotic exposure (in addition to age and previous ERCP) was a risk driver for bactobilia by URB. This may have implications in prophylactic/therapeutic measures.

Behavioural Flexibility: evolutionary past and its role in a changing world

A través de la historia de la vida, gran parte de los organismos han desarrollado estrategias para responder a un mundo en constante cambio. Hoy en día, las actividades humanas producen cambios ambientales a una velocidad sin precedentes, lo cual se traduce en grandes desafíos para la persistencia de biodiversidad. Esta investigación evalúa las respuesta de los animales a los cambios ambientales enfocándose en la flexibilidad del comportamiento como estrategia adaptativa. En una primera aproximación a una escala evolutiva, se otorgan evidencias del vínculo hasta ahora tenue entre la cognición e historias de vida, entregando un claro apoyo a la relación entre longevidad, vida reproductiva y el tamaño del cerebro en mamíferos. La longevidad es el centro de muchas hipótesis respecto a las ventajas de desarrollar un cerebro grande, como por ejemplo en la hipótesis del buffer cognitivo y las respuestas flexibles frente a nuevos ambientes. En un segundo nivel, se abordan factores extrínsecos e intrínsecos que podrían explicar las diferencias individuales en innovación, un componente clave en la flexibilidad del comportamiento. Por medio de una aproximación experimental, se evalúan potenciales escenarios que podrían conducir a consistentes diferencias individuales en uno de los principales factores subyacentes a la innovación (i.e. la motivación), y el potencial control endocrino sobre estos escenarios. Posteriormente, con el objetivo de evaluar la respuesta de los animales frente a los cambios ambientales actuales, se explora la respuesta de los animales frente a una de las actividades humanas mas disruptivas sobre los ecosistemas, la urbanización. Por medio de un analisis filogenetico comparativo a nivel global en aves se abordan los mecanismos implicados en la perdida de biodiversidad observada en ambientes urbanos. Los resultados entregan evidencias sobre la importancia de procesos de dispersión local junto con el papel clave de los rasgos de historia de vida, pero en un sentido diferente al clasicamente pensado. Finalmente por medio de una revisión bibliográfica se entregan evidencias teóricas y empíricas que respaldan el rol clave de la flexibilidad del comportamiento en confrontar los desafíos de una vida urbana. La integración de estos resultados muestra cómo el pasado evolutivo contribuye a hacer frente a los retos ambientales actuales, y pone de relieve posibles consecuencias ante un planeta más cambiante que nunca.

THCCOOH concentrations in whole blood: Are they useful in discriminating occasional from heavy smokers?

Some forensic and clinical circumstances require knowledge of the frequency of drug use. Care of the patient, administrative, and legal consequences will be different if the subject is a regular or an occasional cannabis smoker. To this end, 11-nor-9-carboxy-Δ9-tetrahydrocannabinol (THCCOOH) has been proposed as a criterion to help to distinguish between these two groups of users. However, to date this indicator has not been adequately assessed under experimental conditions. We carried out a controlled administration study of smoked cannabis with a placebo. Cannabinoid levels were determined in whole blood using tandem mass spectrometry. Significantly high differences in THCCOOH concentrations were found between the two groups when measured during the screening visit, prior to the smoking session, and throughout the day of the experiment. Receiver operating characteristic (ROC) curves were determined and two threshold criteria were proposed in order to distinguish between these groups: a free THCCOOH concentration below 3 µg/L suggested an occasional consumption (≤ 1 joint/week) while a concentration higher than 40 µg/L corresponded to a heavy use (≥ 10 joints/month). These thresholds were tested and found to be consistent with previously published experimental data. The decision threshold of 40 µg/L could be a cut-off for possible disqualification for driving while under the influence of cannabis. A further medical assessment and follow-up would be necessary for the reissuing of a driving license once abstinence from cannabis has been demonstrated. A THCCOOH level below 3 µg/L would indicate that no medical assessment is required. Copyright © 2013 John Wiley & Sons, Ltd.

The issue of an older driver, patients addicted to alcohol or drugs, under current psychotropic drug treatment, or diabetic, is discussed in the light of legal provisions and current recommendations. This article also discusses aspects associated with neurological, cardiac and orthopedic issues.

Perspectives on the green construction of the new European Energy Policy

The EU has been one of the main actors involved in the construction process of an international climate change regime, adopting it as an identity sign in the international arena. This activism has reverted in the European political agenda and in the one of its Members States. Therefore, climate change has become a driver for the EU growing participation in energy policy and for its governance evolution. In this context, much attention has been paid to the climate and energy policies integration agreed after the 2007 spring European Council. Apparently, this decision meant a decisive step towards the incorporation of the environmental variable in the energy policy-making. Moreover, the Action Plan [2007-2009] “Energy Policy for Europe” outlined priority actions in a variety of energy-related areas, implying the new European Energy Policy commencement. Against this background, there is still much left to understand about its formulation and its further development. Rooted on the Environmental Policy Integration approach, this paper traces the increasing proximity between environment and energy policies in order to understand the green contribution to the European Energy Policy construction.

New perspectives in the use of ink evidence in forensic science: Part II. Development and testing of mathematical algorithms for the automatic comparison of ink samples analysed by HPTLC

In the first part of this research, three stages were stated for a program to increase the information extracted from ink evidence and maximise its usefulness to the criminal and civil justice system. These stages are (a) develop a standard methodology for analysing ink samples by high-performance thin layer chromatography (HPTLC) in reproducible way, when ink samples are analysed at different time, locations and by different examiners; (b) compare automatically and objectively ink samples; and (c) define and evaluate theoretical framework for the use of ink evidence in forensic context. This report focuses on the second of the three stages. Using the calibration and acquisition process described in the previous report, mathematical algorithms are proposed to automatically and objectively compare ink samples. The performances of these algorithms are systematically studied for various chemical and forensic conditions using standard performance tests commonly used in biometrics studies. The results show that different algorithms are best suited for different tasks. Finally, this report demonstrates how modern analytical and computer technology can be used in the field of ink examination and how tools developed and successfully applied in other fields of forensic science can help maximising its impact within the field of questioned documents.
