Published: November 2010

AbstractBackgroundAlthough screening for tobacco use is increasing with electronic health records and standard protocols, other tobacco-control activities, such as referral of patients to cessation resources, is quite low. In the QUIT-PRIMO study, an online referral portal will allow providers to enter smokers' email addresses into the system. Upon returning home, the smokers will receive automated emails providing education about tobacco cessation and encouragement to use the patient smoking cessation website (with interactive tools, educational resources, motivational email messages, secure messaging with a tobacco treatment specialist, and online support group).MethodsThe informatics system will be evaluated in a comparative effectiveness trial of 160 community-based primary care practices, cluster-randomized at the practice level. In the QUIT-PRIMO intervention, patients will be provided a paper information-prescription referral and then "e-referred" to the system. In the comparison group, patients will receive only the paper-based information-prescription referral with the website address. Once patients go to the website, they are subsequently randomized within practices to either a standard patient smoking cessation website or an augmented version with access to a tobacco treatment specialist online, motivational emails, and an online support group. We will compare intervention and control practice participation (referral rates) and patient participation (proportion referred who go to the website). We will then compare the effectiveness of the standard and augmented patient websites.DiscussionOur goal is to evaluate an integrated informatics solution to increase access to web-delivered smoking cessation support. We will analyze the impact of this integrated system in terms of process (provider e-referral and patient login) and patient outcomes (six-month smoking cessation).Trial RegistrationWeb-delivered Provider Intervention for Tobacco Control (QUIT-PRIMO) - a randomized controlled trial: NCT00797628.

Abstract

Background
Heart transplant (HT) recipients demonstrate limited exercise capacity compared to normal patients, very likely for multiple reasons. In this study we hypothesized that left atrial volume (LAV), which is known to predict exercise capacity in patients with various cardiac pathologies including heart failure and hypertrophic cardiomyopathy is associated with limited exercise capacity of HT recipients.

Methods
We analyzed 50 patients [age 57 ±2 (SEM), 12 females] who had a post-HT echocardiography and cardiopulmonary exercise test (CPX) within 9 weeks time at clinic follow up. The change in LAV (ΔLAV) was also computed as the difference in LAV from the preceding one-year to the study echocardiogram. Correlations among the measured parameters were assessed with a Pearson's correlation analysis.

Results
LAV (n = 50) and ΔLAV (n = 40) indexed to body surface area were 40.6 ± 11.5 ml·m-2 and 1.9 ± 8.5 ml·m-2·year-1, data are mean ± SD, respectively. Indexed LAV and ΔLAV were both significantly correlated with the ventilatory efficiency, assessed by the VE/VCO2 slope (r = 0.300, p = 0.038; r = 0.484, p = 0.002, respectively). LAV showed a significant correlation with peak oxygen consumption (r = -0.328, p = 0.020).

Conclusions
Although our study is limited by a retrospective study design and relatively small number of patients, our findings suggest that enlarged LAV and increasing change in LAV is associated with the diminished exercise capacity in HT recipients and warrants further investigation to better elucidate this relationship.
Sleeping Beauty, Countable Additivity, and Rational Dilemmas
Authors: Ross Jacob 
Published: November 2010

This essay argues that there is a conflict between the principle of Countable Additivity and standard views of how we should update centered or de se beliefs. The latter views, this essay argues, entail a general principle, which the essay calls the Generalized Thirder Principle, that conflicts with the principle of Countable Additivity. The essay then argues that the most plausible response to the conflict between these principles is to maintain that they are both valid and that, when an agent cannot satisfy them both, he or she is faced with a rational dilemma.The essay is divided into five sections. In section 1, it generalizes the one-half and one-third solutions to the Sleeping Beauty problem. In section 2, it argues that while the Generalized Halfer Principle is compatible with Countable Additivity (CA), the Generalized Thirder Principle (GTP) is not. In section 3, it argues that thirders are committed to the GTP since it follows from the premises that underlie each of the main arguments for the one-third solution. In section 4, it discusses the relevance of Dutch book arguments to the conflict between CA and the GTP. And the essay argues that both synchronic and diachronic Dutch book arguments give greater support to CA than to the GTP. In the final section, the essay considers the possible responses to the conflict between CA and the GTP and argues that the most plausible response is to acknowledge the possibility of rational dilemmas.
Processing Afferent Proprioceptive Information at the Main Cuneate Nucleus of Anesthetized Cats
Authors: Leiras Roberto , Velo Patricia , Martín-Cora Francisco , Canedo Antonio 
Published: November 2010

Medial lemniscal activity decreases before and during movement, suggesting prethalamic modulation, but the underlying mechanisms are largely unknown. Here we studied the mechanisms underlying proprioceptive transmission at the midventral cuneate nucleus (mvCN) of anesthetized cats using standard extracellular recordings combined with electrical stimulation and microiontophoresis. Dual simultaneous recordings from mvCN and rostroventral cuneate (rvCN) proprioceptive neurons demonstrated that microstimulation through the rvCN recording electrode induced dual effects on mvCN projection cells: potentiation when both neurons had excitatory receptive fields in muscles acting at the same joint, and inhibition when rvCN and mvCN cells had receptive fields located in different joints. GABA and/or glycine consistently abolished mvCN spontaneous and sensory-evoked activity, an effect reversed by bicuculline and strychnine, respectively; and immunohistochemistry data revealed that cells possessing strychnine-sensitive glycine receptors were uniformly distributed throughout the cuneate nucleus. It was also found that proprioceptive mvCN projection cells sent ipsilateral collaterals to the nucleus reticularis gigantocellularis and the mesencephalic locomotor region, and had slower antidromic conduction speeds than cutaneous fibers from the more dorsally located cluster region.The data suggest that (1) the rvCN–mvCM network is functionally related to joints rather than to single muscles producing an overall potentiation of proprioceptive feedback from a moving forelimb joint while inhibiting, through GABAergic and glycinergic interneurons, deep muscular feedback from other forelimb joints; and (2) mvCN projection cells collateralizing to or through the ipsilateral reticular formation allow for bilateral spreading of ascending proprioceptive feedback information.
Theoretical Description of Ion Conduction in Disordered Systems: From Linear to Nonlinear Response
Authors: Röthel Steffen , Friedrich Rudolf , Lühning Lars , Heuer Andreas 
Published: November 2010

Abstract
The modelling of the ion conduction in disordered systems is analysed from two different perspectives. First, molecular dynamics simulations are employed to extract some basic properties of the hopping dynamics. It turns out that the dynamical processes can be described to a very good approximation as vacancy hopping processes. Second, the information content of nonlinear conductivity experiments, using high electric fields, is elucidated. For this purpose the single-particle dynamics on 1D and 2D model energy landscapes is elucidated numerically and partly analytically. The approaches encompass discrete as well as continuous energy landscapes, yielding complementary results about the dynamics. The impact for the interpretation of experimental data is discussed.

Short and Medium Range Order in Ion-Conducting Glasses Studied by Modern Solid State NMR Techniques
Authors: Eckert Hellmut 
Published: November 2010

Abstract
Glassy ionic conductors have attained considerable importance in the solid state battery technology field. To understand the influence of composition on ionic mobility and transport, information about the local and dynamic environments of the mobile ions in glasses is required. Solid state NMR spectroscopy is one of the most powerful tools for addressing these questions. Our research effort in this area comprises (1) the development of efficient techniques and strategies for the study of disordered materials, (2) the detailed application of optimized measurement and data analysis protocols to different glass systems under systematic compositional variation, and (3) the comprehensive interpretation of the results obtained in the overall literature context. This article attempts to convey a concise overview of our contribution to this field over the period from 2004 to 2010, to describe the most significant insights obtained and to place them into the overall field of Solid State Ionics.
Silver(I)-(poly)chalcogenide Halides – Ion and Electron High Potentials
Authors: Nilges Tom , Bawohl M. , Osters O. , Lange S. , Messel J. 
Published: November 2010

Abstract
Materials with high dynamics in the solid state are of potential interest in semiconductor science and for a great variety of energy applications. In most of the cases the majority of physical properties of such compounds are directly related to their electronic structure. Optimization of properties is therefore correlated with direct or indirect control of this parameter. Compounds with highly mobile ions like the coinage metal cations and the heavy chalcogenide anions can easily be modified chemically or physically to fine tune their electronic structures. The range of adjustable properties lasts from ion conductivity, magneto resistance, thermoelectricity to a reversible redox-driven switch of semiconductivity. Today, the strong demand on clean energy production, the efficient energy transport and energy storage is a major goal for present and oncoming generations. Stable, mixed-conducting materials will play a major role in this process. The ongoing development of coinage metal chalcogenide halides during the last 50 years reflects the fundamental interest in this field. Many interesting and sometimes unexpected properties have been determined recently which substantiates the great potential of this class of materials. Especially the new class of coinage metal polychalcogenide halides is of potential interest due to their drastic modulations of physical properties driven by a fundamental tuning of its electronic structures. Thermopower and thermal diffusivity, two major properties to tune thermoelectricity can be varied in such a way that drastic changes can be addressed in very small temperature ranges close to room temperature. Herein we report on the recent progress of polychalcogenide and chalcogenide halides with the mobile d
10 ions Ag and Cu putting the main focus on silver compounds.
Oscillatory Behavior in the CO-oxidation over Bulk Ruthenium Dioxide — the Effect of the CO/O2 Ratio
Authors: Rosenthal Dirk , Girgsdies Frank , Timpe Olaf , Weinberg Gisela , Schlögl Robert 
Published: November 2010

Abstract
CO oxidation over polycrystalline ruthenium dioxide was monitored in an in-situ XRD setup. The evolution of the bulk state of the catalyst was followed by in-situ XRD during reaction, while the surface morphology and chemical state before and after reaction were investigated by HRSEM and EDX. The commercial RuO2 powder was calcined prior reaction to ensure the formation of completely oxidized RuO2. This pre-calcined RuO2 is initially inactive in CO oxidation regardless of the CO/O2 feed ratio and requires an induction period, the length of which strongly depends whether the catalyst is diluted with boron nitride or not. After this induction period oscillations in the CO2 yield occur under O2-rich conditions only. These oscillations exhibit two time constants for the diluted catalyst, while the low frequency oscillations were not observed in the case of undiluted RuO2. Furthermore, the state of the catalyst after activation in O2-rich feed conditions differs dramatically from the state after activation in CO-rich feed conditions. Firstly, the catalyst activated in an O2-rich atmosphere remains inactive under CO-rich conditions in contrast to the catalyst activated in CO-rich conditions which is afterwards active under all feed ratios examined. Secondly, the surface morphology of the catalyst is quite different. While the apical surfaces of the RuO2 crystals become roughened upon activation in the CO-rich feed, they become facetted under O2 rich activation conditions. Therefore, we conclude that at least two different active surface states on the bulk RuO2 catalyst exist.
Transport Studies of Some 1:1 Copper(I) Perchlorate Complexes in Acetonitrile-Dimethylsulphoxide Mixtures
Authors: Gill Dip Singh , Rana Dilbag Singh , Jauhar Surinder Pal 
Published: November 2010

Abstract
Solvation behaviour of some copper(I) perchlorate complexes has been investigated in binary mixtures of acetonitrile (AN) and dimethylsulphoxide (DMSO) containing 1.0, 0.8, 0.6, 0.4, 0.2 and 0 mol fraction of AN at 298 K by molar conductances and viscosity measurements. The conductance data have been analyzed by using the Shedlovsky method to calculate limiting molar conductance (Λ
o
) and the viscosity data by the Jones–Dole equation to evaluate viscosity B-coefficients of various salts. Limiting ion conductances (λ
i
o
), solvated radii (ri
) and ionic viscosity B
± coefficients in all solvent systems have been evaluated using Gill´s modification based on Bu4NBPh4 as a reference electrolyte. The studies show that all copper(I) complexes are solvated and the extent of solvation is stronger in AN and AN rich regions than in DMSO and DMSO rich regions. The ClO4
- ion is poorly solvated in AN+DMSO mixtures. The viscosity results are in good agreement with the results obtained from the conductance studies.

Authors: Amini Hashem , Axelsson Ove , Raiend Marie , Wikström Johan 
Published: November 2010

AbstractObjectives. To evaluate the additional information of second trimester magnetic resonance imaging (MRI) compared to ultrasound in fetuses with identified or suspected central nervous system (CNS) anomalies and to study the clinical impact of the information on pregnancy management. Design. Prospective study during 2004–2007. The fetal MRI examination was planned to be performed within 3 days after the ultrasound. Setting. Uppsala University hospital. Material. Twenty‐nine pregnant women in whom second trimester ultrasound identified or suspected fetal CNS anomalies. Main outcome measures. Evaluation of the additional information gained from MRI and the consequence it had on pregnancy management. Results. The mean interval between ultrasound and MRI was 1.6 days (range 0–7). In 16 fetuses (55%), MRI verified the ultrasound diagnosis but provided no additional information, while in 10 (35%) MRI gave additional information without changing the management. In 3 (10%), MRI provided additional information that changed the management of the pregnancy. Two of these women were obese. Conclusions. Fetal MRI in the second trimester might be a clinically valuable adjunct to ultrasound for the evaluation of CNS anomalies, especially when ultrasound is inconclusive due to maternal obesity.
Psychological Distress is Associated with Tobacco Smoking and Quitting Behaviour in the Australian Population: Evidence from National Cross-Sectional Surveys
Authors: Leung Janni , Gartner Coral , Dobson Annette , Lucke Jayne , Hall Wayne 
Published: November 2010

Objective: To investigate the association between levels of psychological distress and smoking and quitting behaviours. Method: Data were from two large Australian national household surveys of individuals over 20 years of age. Level of psychological distress was measured by the Kessler 10 scale. Tobacco smoking measures included current smoking status (never, former, current); ex-smokers’ time since quitting; current smokers’ abstinent period in the last 12 months, cigarettes smoked per day, reasons for smoking, and self-report of factors that would motivate quitting; and self-report of factors that motivated smokers to quit in the last 12 months. Multinomial logistic regression was used to assess the relationships between smoking behaviours and psychological distress, while controlling for socio-demographic factors. Results: Current smokers, especially those who smoke more cigarettes per day and those who report less success at quitting or reducing smoking, had higher levels of psychological distress. Ex-smokers were also more likely to experience psychological distress than those who never smoked, but the association weakened with more years since quitting. Current smokers with psychological distress were just as, or more likely, to report planning to quit as those without psychological distress. Smokers who did not plan to quit due to addiction, past failure at quitting, and using smoking for relaxation or to deal with stress were more likely to report psychological distress than those who did not report these reasons. Conclusions: Current smoking and unsuccessful quit attempts in the Australian community were strongly associated with symptoms of psychological distress. Quitting aspirations and influence from general public health interventions were not associated with the smokers’ level of psychological distress.
Multimodalité et expression en langue étrangère dans une plate-forme audio-synchrone
Authors: Chanier Thierry , Vetter Anna 
Published: November 2010

Le développement actuel d'environnements audio-synchrones pose un nouveau défi, non seulement aux concepteurs et aux tuteurs de formations en langues à distance, mais encore aux chercheurs en analyse du discours. Il devient en effet indispensable de comprendre comment s'organise la communication à finalité pédagogique dans ce type d'environnement. L'article aborde ce champ encore peu exploré sous deux angles : l'un méthodologique et l'autre analytique. Nous fournissons, d'une part, un cadre méthodologique pour l'analyse conversationnelle multimodale à partir des notions de média, mode et modalité et, d'autre part, nous définissons les composantes d'une plate-forme synchrone. La partie analytique synthétise d'abord les premiers résultats quantitatifs de l'expérimentation Copéas sur l'usage combiné des modalités audio et clavardage et son impact sur la participation des apprenants. L'analyse indique ensuite, en s'appuyant sur des séquences transcrites, comment s'organise la communication pédagogique lorsque les différents modes (verbaux et non verbaux) s'associent pour structurer et soutenir des conversations en L2. Elle montre que le libre choix des modes et des modalités soutient la production verbale des apprenants. Dans ces conversations, le mode parole occupe tantôt une place prépondérante, tantôt est totalement absent des échanges au profit des modes texte, graphique et iconique. Enfin, nous élargissons le champ de description du discours multimodal en considérant le mode spatial qui s'impose comme le contexte dans lequel chaque transaction doit être située. Ces différents exemples constituent l'occasion de mettre en évidence deux questions connexes : celle de la conception et de l'animation pédagogique dans ces environnements de communication multimodaux à travers le phénomène de polyfocalisation ; et celle de la transcription du discours multimodal.
Les apports possibles de la phraséologie à la didactique des langues étrangères
Authors: Pecman Mojca 
Published: November 2010

L'article explore les avantages d'une analyse phraséologique du discours scientifique face aux difficultés de la maîtrise des formules conventionnelles de ce genre dans une langue étrangère, en l'occurrence en anglais. Notre recherche postule en effet l'existence d'une langue commune aux scientifiques, une langue qui transcende les disciplines, et désormais, grâce à l'anglais, les continents. Pour observer les caractéristiques de cette Langue Scientifique Générale un corpus parallèle a été mis en place recueillant des textes de trois domaines connexes : la chimie, la physique et la biologie. Le dépouillement de ce corpus a abouti à une base de données phraséologiques dont les principes qui ont guidé la construction assurent sa réutilisabilité, notamment pour la réalisation d'applications concrètes à destination des apprenants. L'article présente un projet de construction d'un dictionnaire phraséologique multifonction offrant un double accès aux unités phraséologiques (UP), un accès via la forme des UP (fondé sur une approche sémasiologique de la langue) et un accès via le sens des UP (fondé sur une approche onomasiologique de la langue).
Aides stratégiques dans un environnement d'apprentissage en FLE
Authors: Foucher Anne-Laure , Pothier Maguy 
Published: November 2010

Aider à apprendre, pour peu que l'on choisisse de se situer dans un paradigme d'apprentissage, et, qui plus est, dans une perspective constructiviste, devrait, selon nous, impliquer de prendre en compte les savoirs et les savoir-faire de l'apprenant, ses habitudes et ses manières d'apprendre tout en proposant des interventions didactiques portant, non pas tant sur les savoirs à acquérir, mais sur le processus même de l'apprentissage. Ce sont, en tout cas, ces orientations que nous retenons pour la médiatisation de notre environnement multimédia pour la compréhension orale du FLE en direction d'adultes, en proposant des interventions didactiques, que nous appelons "aides stratégiques", car elles veulent induire de nouvelles stratégies d'apprentissage.Dans cet article, nous tenterons de montrer la cohérence entre nos choix didactiques, fondés sur une vision dynamique de l'apprentissage qui met l'accent sur le processus d'apprentissage, l'individualisation et l'autonomisation de l'apprenant, et les réalisations concrètes auxquelles nous avons abouti en nous appuyant sur des phases de travail médiatisées de notre environnement.
