A suite of standard ocean hydrographic and circulation metrics are applied to the equilibrium physical solutions from 13 global carbon models participating in phase 2 of the Ocean Carbon-cycle Model Intercomparison Project (OCMIP-2). Model-data comparisons are presented for sea surface temperature and salinity, seasonal mixed layer depth, meridional heat and freshwater transport, 3-D hydrographic fields, and meridional overturning. Considerable variation exists among the OCMIP-2 simulations, with some of the solutions falling noticeably outside available observational constraints. For some cases, model-model and model-data differences can be related to variations in surface forcing, subgrid-scale parameterizations, and model architecture. These errors in the physical metrics point to significant problems in the underlying model representations of ocean transport and dynamics, problems that directly affect the OCMIP predicted ocean tracer and carbon cycle variables (e.g., air-sea CO2 flux, chlorofluorocarbon and anthropogenic CO2 uptake, and export production). A substantial fraction of the large model-model ranges in OCMIP-2 biogeochemical fields (+/-25-40%) represents the propagation of known errors in model physics. Therefore the model-model spread likely overstates the uncertainty in our current understanding of the ocean carbon system, particularly for transport-dominated fields such as the historical uptake of anthropogenic CO2. A full error assessment, however, would need to account for additional sources of uncertainty such as more complex biological-chemical-physical interactions, biases arising from poorly resolved or neglected physical processes, and climate change.

This chapter examines the performance measurement of mutual funds when both security selection and market timing management skills are considered. In an option replication approach, linear and quadratic coefficients of the Treynor and Mazuy regression are combined to assess performance in presence of market timing. This new correction has the potential to overcome the “artificial timing” bias and delivers particularly encouraging results on a sample of 1,413 U.S. mutual funds selected for an empirical analysis. Unlike alternative approaches proposed in the literature, most of positive market timers seem to be rewarded for the convexity they add to their portfolio, while negative market timers are penalized, and a correlation between abnormal performance and the convexity parameter is found.

Tolerance of anthropic environment has allowed large carnivores to recolonize and to be reintroduced within Europe in the last forty years. This indicates that, even in areas where the return of large carnivores seems unlikely, their presence and establishment is possible, even in highly modified environments. In the current context of the return of large carnivores in Europe, there is a need for scientific conservation tools to assess the full potential and consequences of the return of large carnivores in Europe, and in particular to evaluate potential impact on game and livestock. Today, the return of the Eurasian Lynx (Lynx lynx) in areas where it has been absent for long periods is becoming increasingly probable, and this requires further investigations. Three main lines of research will be particularly important: the use of habitat by Eurasian Lynx, the effect of habitat on predation behavior, and potential sources of conflict with human populations. The research project will address fine scale habitat use, the effect of prey‘s spatial variation on Lynx predation behavior, the use of different statistical methods to estimate Lynx‘s viability in various habitats and landscape, and a review of current conflicts throughout Europe. Results should allow better understanding of the Lynx redeployment potentials in lowland Western Europe [less ▲]

Introduction: Inhibitors of sodium-glucose cotransporters type 2 (SGLT2), which increase urinary glucose excretion independently of insulin, are proposed as a novel approach for the management of type 2 diabetes mellitus (T2DM). Areas covered: An extensive literature search was performed to analyze the pharmacokinetic characteristics, toxicological issues and safety concerns of SGLT2 inhibitors in humans. This review focuses on three compounds (dapagliflozin, canagliflozin, empagliflozin) with results obtained in healthy volunteers (including drug-drug interactions), patients with T2DM (single dose and multiple doses) and special populations (those with renal or hepatic impairment). Expert opinion: The three pharmacological agents share an excellent oral bioavailability, long half-life allowing once-daily administration, low accumulation index and renal clearance, the absence of active metabolites and a limited propensity to drug-drug interactions. No clinically relevant changes in pharmacokinetic parameters were observed in T2DM patients or in patients with mild/moderate renal or hepatic impairment. Adverse events are a slightly increased incidence of mycotic genital and rare benign urinary infections. SGLT2 inhibitors have the potential to reduce several cardiovascular risk factors, and cardiovascular outcome trials are currently ongoing. The best positioning of SGLT2 inhibitors in the armamentarium for treating T2DM is still a matter of debate. [less ▲]

Because accurate characterization of health state is important for managing dairy herds, we propose to validate the use of a linear state-space model (LSSM) for evaluating monthly somatic cell scores (SCSs). To do so, we retrieved SCS from a dairy database and collected reports on clinical mastitis collected in 20 farms, during the period from January 2008 to December 2011 in the Walloon region of Belgium. The dependent variable was the SCS, and the independent variables were the number of days from calving, year of calving and parity. The LSSM also incorporated an error-free underlying variable that described the trend across time as a function of previous clinical and subclinical status. We computed the mean sum of squared differences between observed SCS and median values of the posterior SCS distribution and constructed the receiver operating characteristic (ROC) curve for SCS thresholds going from 0 to 6. Our results show SCS estimates are close to observed SCS and area under the ROC curve is higher than 90%. We discuss the meaning of the parameters in light of our current knowledge of the disease and propose methods to incorporate, in LSSM, this knowledge often expressed in the form of ordinary differential equations.

ABSTRACT Background. The ALERT algorithm, an effective compression-only phone cardiopulmonary resuscitation (CPR) protocol has the potential to help bystanders initiate CPR. This study evaluates the psychological impact of the CPR’s practice on untrained persons (UP). Methods. This is a quasi experimental longitudinal study (n = 153). We used: demographics data, CPR’ emotional characteristics; the Peritraumatic Dissociative Experiences Questionnaire ; the Way of Coping Check List and the Impact of Event Scale. Findings. Two psychological profiles: UP at high risk to develop a post traumatic disorder (higher average scores ; high emotional distress during the CPR) versus UP at low risk. Discussion. These preliminary results highlight the importance of identifying the psychological profile of the UP. For a CPR, UP at high risk should be treated differently: first, take the time to reduce emotional distress and then only talk about the CPR. This step could reduce the risk for PTSD [less ▲]

Methods validation is mandatory in order to assess the fitness of purpose of the developed analytical method. Of core importance at the end of the validation is the evaluation of the reliability of the individual results that will be generated during the routine application of the method. Regulatory guidelines provide a general framework to assess the validity of a method, but none address the issue of results reliability. In this study, a Bayesian approach is proposed to address this concern. Results reliability is defined here as “the probability of an analytical method to provide analytical results within predefined acceptance limits around their reference or conventional true concentration values over a defined concentration range and under given environmental and operating conditions.” By providing the minimum reliability probability needed for the subsequent routine application of the method, as well as specifications or acceptance limits , the proposed Bayesian approach provides the effective probability of obtaining reliable future analytical results over the whole concentration range investigated. This is summarized in a single graph: the reliability profile. This Bayesian reliability profile is also compared to two frequentist approaches, the first one derived from the work of Dewé et al. [Dewé W., Govaerts B., Boulanger B., Rozet E., Chiap P., Hubert Ph., Chemometr. Intell. Lab. Syst. 85 (2007) 262-268] and the second proposed by Govaerts et al. [B. Govaerts, W. Dewé, M. Maumy, B. Boulanger, Qual. Reliab. Engng. Int. 24 (2008) 667-680]. Furthermore, to illustrate the applicability of the Bayesian reliability profile, this approach is also applied here to a bioanalytical method dedicated to the determination of ketoglutaric acid (KG) and hydroxymethylfurfural (HMF) in human plasma by SPE-HPLC-UV.

Economic evaluations of animal health surveillance systems are critical components of the assessment of their long-term sustainability and the improvement of their cost- effectiveness. Social costs and benefits of health information release through the surveillance systems are fundamental determinants of the acceptability and efficacy of surveillance and are often neglected in the evaluation process. This study presents the evaluation of social costs and benefits of Highly Pathogenic Avian Influenza (HPAI) surveillance in Vietnam. Three field studies were conducted in the South and North of the country. Data on animal health information flow networks and social costs and benefits were collected using participatory approaches. Non-monetary costs and benefits were quantified using a newly developed tool based on stated choice method and participatory techniques. The study showed that private actors incur many transaction costs in reporting the information. However social costs mainly arise from price drops due to information release on market which has strong influences on the decision to disclose sanitary information. This applies at all levels including farmers and veterinary authorities. Private actors of the poultry sector valued information on occurring disease outbreaks, which is perceived as a social benefit. However avian influenza information is scarcely disclosed in private networks as stakeholders fear its potential impact on markets. [less ▲]
