How unethical actions can be learned : the analysis of the sporting life courses of doping athletes

The aim of the present article was to present a specific activity approach called the 'life course of a practice' that could be used for the analysis of the long-term dynamic of learning within diverse social practices. The cases of unethical actions (doping) within a population of high-level athletes were examined, considering they could be fruitful exam- 10 ples for this type of analysis. After describing the theoretical construct 'life course of a practice', the places of these unethical actions in the sporting life courses and elements that characterize their emergence in the long-term dynamics are described. Last, targeted prevention measures of unethical actions over a lifetime are presented.

How to use the standard model with own data?

In this work discuss the use of the standard model for the calculation of the solvency capital requirement (SCR) when the company aims to use the specific parameters of the model on the basis of the experience of its portfolio. In particular, this analysis focuses on the formula presented in the latest quantitative impact study (2010 CEIOPS) for non-life underwriting premium and reserve risk. One of the keys of the standard model for premium and reserves risk is the correlation matrix between lines of business. In this work we present how the correlation matrix between lines of business could be estimated from a quantitative perspective, as well as the possibility of using a credibility model for the estimation of the matrix of correlation between lines of business that merge qualitative and quantitative perspective.

Productivity in southern European small firms: When and how work organization complements process innovation

The aim of this paper is to analyse the effects of human capital, advanced manufacturing technologies (AMT), and new work organizational practices on firm productivity, while taking into account the synergies existing between them. This study expands current knowledge in this area in two ways. First, in contrast with previous works, we focus on AMT and not ICT (information and communication technologies). Second, we use a unique employer-employee data set for small firms in a particular area of southern Europe (Catalonia, Spain). Using a small firm data set, allows us to analyse the particular case of small and medium enterprises, since we cannot assume they have the same characteristics as large firms. The results provide evidence in favor of the complementarity hypothesis between human capital, advanced manufacturing technologies, and new work organization practices, although we show that the complementarity effects depend on what type of work organization practices are used by a firm. For small and medium Catalan firms, the only set of work organization practices that improve the benefits of human capital and technology investment are those practices which are more quality oriented, such as quality circles, problem-solving groups or total quality management.

Maintien des capacités des myopathes ou l'art de prescrire l'exercice physique [How to maintain the motor capacities in neuromuscular disorders or the art to prescribe physical exercises].

Optimum management of non-acquired neuromuscular disorders requires a multidisciplinary approach in order to prevent secondary complications related to the progression of the disease and to maintain the patient's independency in daily activities. For treatments, the physiotherapists and occupational therapists must have precise and measurable goals to quantify muscle strength and functions in conjunction with a specialist in neurorehabilitation. Examples of simple motor scores or scales are given in order to transmit precise information to the GP and the multidisciplinary team, and type of orthosis and physiotherapy programmes are given as pieces of advice to assume the follow-up of patients.

Bisphosphonate-related osteonecrosis of the jaws: how to manage cancer patients.

Bisphosphonate related osteonecrosis of the jaw (BRONJ) is defined as exposed necrotic bone appearing in the jaws of patients treated by systemic IV or oral BPs never irradiated in the head and neck area and that has persisted for more than 8 weeks. More than 90% of cases of osteonecrosis of the jaw have been in patients with cancer who received IV-BPs. The estimate of cumulative incidence of BRONJ in cancer patients with IV-BPs ranges from 0.8% to 18.6%. The pathogenesis of BRONJ appeared related to the potent osteoblast-inhibiting properties of BPs which act by blocking osteoclast recruitment, decreasing osteoclast activity and promoting osteoclast apoptosis. Dental extractions are the most potent local risk factor. Cancer patients wearing a denture could also be at increased risk of BRONJ. Non-healing mucosal breaches caused by dentures could be a portal for the oral flora to access bone, while the oral mucosa of patients on IV-BPs could also be defective. Whether periodontal disease is a risk factor for BRONJ remains controversial. Preventive measures are fundamental. Nevertheless, some teams have questioned its cost-effectiveness. The perceived limitations of surgical therapy of BRONJ led to the restriction of aggressive surgery to symptomatic patients with stage 3 BRONJ. The evidence-based literature on BRONJ is growing but there are still many controversial aspects.

Schistosomiasis epidemiology and control: how did we get here and where should we go?

Although a disease of great antiquity, scientific studies of schistosomiasis began only 150 years ago. The complete life-cycle was not described until just before the First World War, making it possible at last to plan proper community control programmes. Inadequate tools prevented their effective implementation until well after the Second World War when new tools became available, thanks to the newly formed World Health Organization. Molluscicides spearheaded control programmes until the late 1970s but were then replaced by the newly developed, safe drugs still used today. Whatever the method used, the initial goal of eradication was, in the light of experience and cost, gradually replaced by less ambitious targets; first to stop transmission and then to reduce morbidity. The most successful programmes combined several methods to minimise reinfection after chemotherapy. Comparisons between different programmes are difficult without using appropriate, standardised diagnostic techniques and the correct epidemiological measurements. Some examples will be presented, mainly from our studies on Schistosoma mansoni in Kenya. Drug resistance on a scale comparable with malaria has not occurred in schistosomiasis but the likely withdrawal of all drugs except praziquantel leaves its control extremely vulnerable to this potential problem. An effective, affordable vaccine for use in endemic countries is unlikely to be ready for at least 5 years, and developing strategies for its use could take a further decade or more, judging from experience with drugs and molluscicides. In the interim, by analogy with malaria, the most cost-effective approach would the use of drugs combined with other methods to stop transmission, including molluscicides. The cost of molluscicides needs to be reduced and fears allayed about their supposedly adverse ecological effects.

How Low Can We Go in Contrast-Enhanced CT Imaging of the Chest?: A Dose-Finding Cadaver Study Using the Model-based Iterative Image Reconstruction Approach.

RATIONALE AND OBJECTIVES: Dose reduction may compromise patients because of a decrease of image quality. Therefore, the amount of dose savings in new dose-reduction techniques needs to be thoroughly assessed. To avoid repeated studies in one patient, chest computed tomography (CT) scans with different dose levels were performed in corpses comparing model-based iterative reconstruction (MBIR) as a tool to enhance image quality with current standard full-dose imaging. MATERIALS AND METHODS: Twenty-five human cadavers were scanned (CT HD750) after contrast medium injection at different, decreasing dose levels D0-D5 and respectively reconstructed with MBIR. The data at full-dose level, D0, have been additionally reconstructed with standard adaptive statistical iterative reconstruction (ASIR), which represented the full-dose baseline reference (FDBR). Two radiologists independently compared image quality (IQ) in 3-mm multiplanar reformations for soft-tissue evaluation of D0-D5 to FDBR (-2, diagnostically inferior; -1, inferior; 0, equal; +1, superior; and +2, diagnostically superior). For statistical analysis, the intraclass correlation coefficient (ICC) and the Wilcoxon test were used. RESULTS: Mean CT dose index values (mGy) were as follows: D0/FDBR = 10.1 ± 1.7, D1 = 6.2 ± 2.8, D2 = 5.7 ± 2.7, D3 = 3.5 ± 1.9, D4 = 1.8 ± 1.0, and D5 = 0.9 ± 0.5. Mean IQ ratings were as follows: D0 = +1.8 ± 0.2, D1 = +1.5 ± 0.3, D2 = +1.1 ± 0.3, D3 = +0.7 ± 0.5, D4 = +0.1 ± 0.5, and D5 = -1.2 ± 0.5. All values demonstrated a significant difference to baseline (P < .05), except mean IQ for D4 (P = .61). ICC was 0.91. CONCLUSIONS: Compared to ASIR, MBIR allowed for a significant dose reduction of 82% without impairment of IQ. This resulted in a calculated mean effective dose below 1 mSv.
