The purpose of this paper is to highlight the mobile services developed by the Rector Gabriel Ferraté Library (BRGF) of the Universitat Politècnica de Catalunya (UPC Barcelona Tech) in Barcelona, Spain.We hope this paper will be of use to other libraries exploring new technologies for communicating and delivering their services to users at a time when mobile services are an emerging topic in librarianship and information science literature. By setting out the successive steps involved in the as yet unfinished process of building our mobile services portfolio, we aim to offer a detailed picture of the mobile services and features offered by a university library from a case study perspective.The main topics to be discussed include:- The BRGF’s mobile website, including the information available, its interactivecapabilities and the services it provides to its users.- The mobile-friendly version of UPCommons (the UPC Library Service’s institutionalrepositories).- The UPC Library Service’s mobile OPAC.- The mobile version of u-win (BRGF’s videogame service).- The use of QR codes to deliver information to mobile devices.- Text message notifications.Additional topics for discussion include:- The library’s organisation and the organisational concepts that underpin andmake possible its technological developments (including mobile).- BRGF’s concern regarding the reduction of investment in the development of mobile services.- The criteria and tools used to guide the library’s decisions regarding thedesign and orientation of current and future mobile services.- How mobile services can help to improve the image of the library as a leadingtechnology site.- Selected mobile features that BRGF plans to offer in the near future.Ultimately, this paper aims to delineate the effectiveness and potential of deliveringlibrary services by the preferred means of communication of a new generation of studentsand teachers.

Abstract This PhD thesis addresses the issue of alleviating the burden of developing ad hoc applications. Such applications have the particularity of running on mobile devices, communicating in a peer-to-peer manner and implement some proximity-based semantics. A typical example of such application can be a radar application where users see their avatar as well as the avatars of their friends on a map on their mobile phone. Such application become increasingly popular with the advent of the latest generation of mobile smart phones with their impressive computational power, their peer-to-peer communication capabilities and their location detection technology. Unfortunately, the existing programming support for such applications is limited, hence the need to address this issue in order to alleviate their development burden. This thesis specifically tackles this problem by providing several tools for application development support. First, it provides the location-based publish/subscribe service (LPSS), a communication abstraction, which elegantly captures recurrent communication issues and thus allows to dramatically reduce the code complexity. LPSS is implemented in a modular manner in order to be able to target two different network architectures. One pragmatic implementation is aimed at mainstream infrastructure-based mobile networks, where mobile devices can communicate through fixed antennas. The other fully decentralized implementation targets emerging mobile ad hoc networks (MANETs), where no fixed infrastructure is available and communication can only occur in a peer-to-peer fashion. For each of these architectures, various implementation strategies tailored for different application scenarios that can be parametrized at deployment time. Second, this thesis provides two location-based message diffusion protocols, namely 6Shot broadcast and 6Shot multicast, specifically aimed at MANETs and fine tuned to be used as building blocks for LPSS. Finally this thesis proposes Phomo, a phone motion testing tool that allows to test proximity semantics of ad hoc applications without having to move around with mobile devices. These different developing support tools have been packaged in a coherent middleware framework called Pervaho.

La conviction d'être le peuple élu s'enracine au coeur de la foi d'Israël. Mais elle justifia aussi par réaction tous les antisémitismes. La Bible, pourtant, ne nous fait pas entendre qu'un seul discours sur l'élection. A trop vite tirer à soi tel passage, on en vient à travestir dangereusement son message. En réalité la critique des dérives intégristes auxquelles peut donner et a donné lieu le thème de l'élection d'Israël est le fait de l'Ancien Testament lui-même. Il est vrai que dans les temps d'oppresion et de déportation la conscience d'être le peuple de Dieu a permis à Israël de fortifier son espérance et d'assurer son identité. Et ce fut là, notamment, le grand dessein auquel se consacrèrent les auteurs successsifs du Deutéronome, à l'époque de la domination assyrienne, puis de l'exil babylonien. Mais il est tout aussi vrai qu'à chaque fois aussi se sont levés des hommes avertis, dans la foulée des propnètes de jadis, pour mettre en garde contre la tentation du nombrilisme voire de l'exclusivisme ravageur. L'histoire d'Abraham réécrite au retour de l'exil, en est l'exemple le plus impressionnant, qui souligne combien Dieu n'a cessé d'élargir à tous les pepes son électon et sa bénédiction.

El análisis de la interacción individuo-paisaje presenta numerosas perspectivas de estudio vinculadas a la generación e interpretación de simbolismos e imaginarios. La capacidad significante y/o de evocación comunicativa del paisaje encuentra, en la comunicación intrapersonal, una argumentación relevante en el proceso de construcción de un aparato teórico que permita estudiar el proceso de apropiación y vivencia del paisaje en términos de manifestación comunicativa. El despliegue de un aparato teórico que permita interpretar el mensaje del paisaje así como descodificar su discurso intangible, representa el objetivo principal de la investigación que se presenta a continuación.

La necesidad de descodificar los significados inherentes al paisaje, la interactuación sociedadpaisaje (comunicación intra e interpersonal) y, más recientemente, los usos de paisaje a modo de aparador territorial mediático en el ámbito, por ejemplo, de la comunicación publicitaria, del citymarketing o del place branding (comunicación masiva), sirven para plantear el estudio de lo que, de algún modo, representa la persuasión del paisaje, la cual incluye claros tintes emocionales y simbólicos y, por tanto, también comunicacionales. El paisaje en su condición de imagen y/o rostro del territorio acumula la esencia del mensaje implícito en el espacio, posicionándose, de este modo, como la gran metáfora comunicativa de la ciudad. En este sentido, el trabajo de comunicación específico con el intangible paisajístico, unido a la reciente explosión de las denominadas geografías emocionales, plantea una teoría del mensaje territorial basada en la unión de las variables geografía, paisaje, emoción y comunicación. Históricamente, de los estudios de paisaje se han ocupado los geógrafos, arquitectos, historiadores, sociólogos o ambientólogos, entre muchos otros, sin embargo, el paisaje se ha mantenido poco explorado desde la perspectiva de la comunicación. En este sentido, es notoria la proliferación de análisis que ponen el acento en el papel que desarrolla el territorio como mediador de procesos de comunicación o en el estudio de procesos de retroalimentación entre la sociedad y sus espacios (cognición y/o percepción). El actual mercadeo identitario con los lugares se concreta en la creciente producción de marcas territoriales, las cuales acumulan, en los últimos tiempos, un importante protagonismo.

JCM és una empresa dedicada al disseny de sistemes de control d’accés. Disposa d’uns equips elèctrics amb molts paràmetres configurables, així es poden utilitzar en molts tipus d’instal•lació. Aquets paràmetres són configurables pels clients. JCM, disposa d’un servei d’atenció telefònica (SAT), que intenta donar solucions a tots els problemes que puguin sorgir als clients. Sovint, no poden donar suport als dubtes dels clients per culpa de la poca informació que reben a través del client. L'objectiu del projecte és resoldre el problema de falta d'informació i mala comunicació per millorar la qualitat del servei que ofereix el SAT. La solució, no ha d’alterar el cost de producció del producte. S’ha de tenir en compte també que els equips poden estar instal•lats en qualsevol part del món i que només es poden utilitzar recursos de fàcil accés per tots els clients. Per complir amb aquests objectius, emetrem un missatge, a través del brunzidor del equip, amb la informació de configuració de l'equip. Aquest missatge viatjarà a través de la xarxa telefònica fins al SAT. Un cop allà, el descodificarem i n'enviarem les dades a un PC perquè pugui presentar les dades sobre la configuració de una forma clara pel SAT.

The purpose of this paper is to study the diffusion and transformation of scientific information in everyday discussions. Based on rumour models and social representations theory, the impact of interpersonal communication and pre-existing beliefs on transmission of the content of a scientific discovery was analysed. In three experiments, a communication chain was simulated to investigate how laypeople make sense of a genetic discovery first published in a scientific outlet, then reported in a mainstream newspaper and finally discussed in groups. Study 1 (N=40) demonstrated a transformation of information when the scientific discovery moved along the communication chain. During successive narratives, scientific expert terminology disappeared while scientific information associated with lay terminology persisted. Moreover, the idea of a discovery of a faithfulness gene emerged. Study 2 (N=70) revealed that transmission of the scientific message varied as a function of attitudes towards genetic explanations of behaviour (pro-genetics vs. anti-genetics). Pro-genetics employed more scientific terminology than anti-genetics. Study 3 (N=75) showed that endorsement of genetic explanations was related to descriptive accounts of the scientific information, whereas rejection of genetic explanations was related to evaluative accounts of the information.

If 'the dose makes the poison', and if the context of an exposure to a hazard shapes the risk as much as the innate character of the hazard itself, then what is 'toxic' and what is 'nontoxic'? This article is intended to help readers and communicators: anticipate that concepts such as 'toxic' and 'nontoxic' may have different meanings to different stakeholders in different contexts of general use, commerce, science, and the law; recognize specific situations in which terms and related information could potentially be misperceived or misinterpreted; evaluate the relevance, reliability, and other attributes of information for a given situation; control actions, assumptions, interpretations, conclusions, and decisions to avoid flaws and achieve a desired outcome; and confirm that the desired outcome has been achieved. To meet those objectives, we provide some examples of differing toxicology terminology concepts and contexts; a comprehensive decision-making framework for understanding and managing risk; along with a communication and education message and audience-planning matrix to support the involvement of all relevant stakeholders; a set of CLEAR-communication assessment criteria for use by both readers and communicators; example flaws in decision-making; a suite of three tools to assign relevance vs reliability, align know vs show, and refine perception vs reality aspects of information; and four steps to foster effective community involvement and support. The framework and supporting process are generally applicable to meeting any objective.

In a recent issue of Critical Care, den Hartog and colleagues show an association between spontaneous hypothermia, defined by an admission body temperature < 35°C, and poor outcome in patients with coma after cardiac arrest (CA) treated with therapeutic hypothermia (TH). Given that TH alters neurological prognostication, studies aiming to identify early markers of injury severity and outcome are welcome, since they may contribute overall to optimize the management of comatose CA patients. This study provides an important message to clinicians involved in post-resuscitation care and raises important questions that need to be taken into account in future studies.

We study the strategic interaction between a decision maker who needs to take a binary decision but is uncertain about relevant facts and an informed expert who can send a message to the decision maker but has a preference over the decision.We show that the probability that the expert can persuade the decision maker to take the expert's preferred decision is a hump-shaped function of his costs of sending dishonest messages.

Introduction: Seulement 25-30% des patients avec syndrome coronarien aigu (SCA) atteignent les valeurs cibles de LDL-cholestérol (LDL-C) dans leur suivi. L'objectif de cette étude pré/post est de tester une alerte automatique centralisée pour améliorer les pratiques. L'alerte apparaît sur les feuilles de laboratoire pour tous les patients ayant une troponine >= 0,1 microg/l; elle précise notamment les recommandations en matière de profil lipidique (LDL-C cible) à atteindre. Méthode: Tout patient admis au CHUV pour un SCA avec troponine >= 0,1 microg/l était éligible. Durant les 2 phases de l'étude (du 23.11.2008 au 15.08.201), un bilan lipidique complet a été dosé à l'admission et à 3 mois. La phase 1 (pré) était observationnelle et le message d'alerte a été introduit pour la phase 2 (post). Résultats: Phase 1: 157 patients dont 56 (35%) étaient déjà traités par une statine: 114 hommes (âge moyen 62 ans) et 43 femmes (73 ans). LDL-C moyen: 3,4 ± 1,0 mmol/l à l'admission et 2,4 ± 0,8 mmol/l à 3 mois (p <0,001). Phase 2: 140 patients dont 42 (30%) étaient déjà traités par une statine: 116 hommes (62 ans) et 24 femmes (67 ans). LDL-C moyen: 3,4 ± 1,1 mmol/l à l'admission et 2,2 ± 1,0 mmol/l à 3 mois (p <0,001). 66 % (104 patients) atteignent un LDL-C cible < = 2,6 mmol/l à 3 mois lors de la phase 1, versus 78% (110 patients) lors de la phase 2 (p = 0,2). Les patients déjà sous statine à l'admission ont une faible diminution du LDL-C à 3 mois (de 2,8 à 2,5 mmol/l phase 1, p <0,05; de 2,5 à 2,6 mmol/l phase 2, p = 0.2), alors que les patients chez qui une statine est introduite à l'admission ont une baisse significative et plus importante du LDL-C à 3 mois (de 3,8 à 2,3 mmol/l phase 1, p <0,001; de 3,7 à 2,1 mmol/l phase 2, p <0,001) que les patients déjà sous statine au préalable. Conclusion: La phase observationnelle montre un taux élevé de patients atteignant un LDL-C cible à 3 mois. L'introduction d'une alarme automatique centralisée n'a pas permis d'améliorer ces résultats. Par contre, les patients arrivant à l'hôpital avec un SCA et étant déjà sous statine devraient avoir une intensification de leur traitement.

The purpose of this article is to identify tobacco and cannabis co-consumptions and consumers' perceptions of each substance. A qualitative research including 22 youths (14 males) aged 15-21 years in seven individual interviews and five focus groups. Discussions were recorded, transcribed verbatim and transferred to Atlas.ti software for narrative analysis. The main consumption mode is cannabis cigarettes which always mix cannabis and tobacco. Participants perceive cannabis much more positively than tobacco, which is considered unnatural, harmful and addictive. Future consumption forecasts thus more often exclude tobacco smoking than cannabis consumption. A substitution phenomenon often takes place between both substances. Given the co-consumption of tobacco and cannabis, in helping youths quit or decrease their consumptions, both substances should be taken into account in a global approach. Cannabis consumers should be made aware of their tobacco use while consuming cannabis and the risk of inducing nicotine addiction through cannabis use, despite the perceived disconnect between the two substances. Prevention programs should correct made-up ideas about cannabis consumption and convey a clear message about its harmful consequences. Our findings support the growing evidence which suggests that nicotine dependence and cigarette smoking may be induced by cannabis consumption.

BACKGROUND: Little is known about coping specificities, as operationalization of the concept of affect regulation, in borderline personality disorder (BPD). It is most important to take into account methodological criticisms addressed to the self-report questionnaire approach and to compare BPD coping specificities to the ones of neighbouring diagnostic categories, such as bipolar disorder (BD). SAMPLING AND METHODS: The present exploratory study compared the coping profiles of N = 25 patients presenting BPD to those of N = 25 patients presenting BD and to those of N = 25 healthy controls. All participants underwent a clinical interview that was transcribed and rated using the Coping Patterns observer-rater system. RESULTS: Results partially confirmed study hypotheses and showed differences between BPD patients and healthy controls in all coping domains (competence, resources and autonomy), whereas the only coping domain presenting a BPD-specific lack of skills, compared with the BD patients, was autonomy, a set of coping strategies facing stress appraised as challenge. These coping processes were linked to general and BPD symptomatology. CONCLUSIONS: These results extend conclusions of earlier studies on affect regulation processes in BPD and bear important clinical implications, in the context of dialectical behavior therapy and other therapeutic approaches. Limitations of this exploratory study, such as the small sample size, are acknowledged. Copyright © 2012 John Wiley & Sons, Ltd. KEY PRACTITIONER MESSAGE: Coping can be reliably assessed in the narrative process in an non-structured interview frame. Patients with borderline personality disorder present with a specific lack of skills in affect regulation related to autonomy issues, compared to patients with bipolar disorder and healthy controls. Lack of skills in accommodation to distressing emotions in borderline personality disorder is related to symptom gravity and may be treated using radical acceptance strategies.

Die Bestrebungen für eine Regierungsreform in der Schweiz lassen sich weit zurückverfolgen, sie führten aber zu keinen weitreichenden Ände-rungen betreffend das Regierungsorgan. Hauptsächliche Folgen waren Verwaltungsreformen. Schrittweise oder inkrementalistische Änderungen sind feststellbar. Sie betreffen die sogenannte Organisationsgewalt, die Bundeskanzlei, die Führungsstäbe, vor allem aber die Staatssekretärinnen und Staatssekre-täre. Die Leitplanken und die Zusatzbotschaft aus dem Jahr 2010 des Bun-desrates für eine Regierungsreform richten sich nach den Ergebnissen des Beitrages nach inkrementalistischen Entwicklungen aus. Mit der Verlängerung der Amtsdauer der Bundespräsidentin oder des Bundes-präsidenten könnte zudem ein neuer Entwicklungspfad begründet wer-den. Dem aktuellen Reformanstoss werden auf Grund der verwendeten Erklärungsansätze erhöhte Chancen zugemessen. Les efforts pour une réforme du gouvernement en Suisse remontent loin, mais ils n'ont pas abouti à des modifications de longue portée concernant l'organe gouvernemental. Les résultats principaux étaient des réformes de l'administration. Des modifications graduelles ou incrémentales sont détectables. Elles concernent le pouvoir d'organisation, la Chancellerie fédérale, les états-majors, mais surtout les secrétaires d'État. Les axes principaux et le message additionnel pour une réforme du gouvernement sont orientés vers les développements incrémentales constatés selon les recherches effectuées. L'allongement de la durée de fonction du président de la Confédération pourrait en plus constituer un nouveau chemin du développement. L'impulsion actuelle pour une réforme a des chances élevées d'aboutir selon les essais d'explication.
