Prolonged Abstinence and Changes in Alcoholic Personality: A NEO PI-R Study  [PDF]
Isabelle Boulze, Michel Launay, Bertrand Nalpas
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.54041
Abstract:

Many studies have examined the risk factors for relapse in alcohol-dependent patients within the first year of treatment, and have generally focused on two personality dimensions: emotional instability and difficulty in establishing relationships. In this study, we examine if these weaknesses remain in prolonged alcohol abstinence. To do so, we administer the NEO PI-R to two groups of subjects. Group 1, Inactive Drinkers (ID), consists of 51 patients with at least two years of abstinence (average length of abstinence for this group is 6.2 years); Group 2, Recently Detoxified Drinkers (RDD), comprises 93 patients who have recently ceased consuming alcohol. Based on NEO PI-R scores, our results evidence that inactive drinkers experience significant reduction in emotional instability and improvement in relationships to others. We further observe that, with long-term abstinence, these personality dimensions normalize, ceasing to be risk factors for relapse. Additionally, we find that this long-term amelioration of traits altered by alcohol amounts to an improved behavioral adaptation to life events rather than an actual change in personality.

Variation of Interpersonal Values Following Alcohol Withdrawal in Alcoholics Seeking Treatment: 12-Month Longitudinal Study  [PDF]
Isabelle Boulze, Michel Launay, Bertrand Nalpas
Psychology (PSYCH) , 2016, DOI: 10.4236/psych.2016.71004
Abstract: We performed a community research program in order to analyze the evolution of interpersonal values following alcohol withdrawal in alcoholics attending to a self-help group. The Gordon questionnaire on interpersonal values was administered every 3 months during one year to 145 individuals having recently stopped drinking. At baseline, scores of 5 interpersonal categories (dependence, conformism, consideration, independence, kindness) were in the medium interval of usual values while that of command category was low, specifically in men. Values of conformism and independence increased according to time while those of dependence and consideration decreased but the differences were significant only in those who remained abstinent all along the observation period. In those who relapsed, there were no modifications; however, sharing these values might have allowed these subjects to be less isolated. We will describe in details the nature of these evolutions.
“Apprentis Chercheurs” in Drugs Disorders: A New Concept in Prevention Strategy  [PDF]
Bertrand Nalpas, Jérémie Cordonnier, Morgane Le Bras, Dominique Donnet-Kamel
Creative Education (CE) , 2014, DOI: 10.4236/ce.2014.521205
Abstract: We report a new strategy based on scientific education for sensitizing teenagers to the addiction-related harms. This strategy is diverted from a program called “Apprentis Chercheurs”. Pairs of young adolescents are welcome in research laboratories working on addiction all along the school year. They are fully integrated in the research team and directly participate to the experiments under the supervision of a senior researcher. At the end of the school year, they orally communicate their results to other students of their schools, their teachers, their parents and the research team in a peer-to-peer approach during a scientific conference organized within every participant research center.

Substance Abuse Treatment, Prevention, and Policy , 2006, DOI: 10.1186/1747-597x-1-5
Abstract: 45 patients were included and followed-up during 291 ± 114 days. The mean initial ASI scores (± SD) were: medical (M) = 0.39 ± 0.3, working-income (ER) = 0.5 ± 0.3, alcohol (A) = 0.51 ± 0.2, illicit drugs (D) = 0.07 ± 0.08, legal (L) = 0.06 ± 0.13, familial and social environment (FS) = 0.34 ± 0.26, psychological (P) = 0.39 ± 0.22. The total number of procedures was 1341 (29.8 per patient) corresponding to 754.4 hours (16.7 per patient). The intensity of management peaked during the first month of treatment, and then declined rapidly; the maximum incidence of abstinence was observed during the 3rd month of management. Interviews with patients, group therapy and staff meetings represented 68.7%, 9.9% and 13.9% of all procedures, respectively. In patients with severe dependence, as compared to moderate, management was twice as intense in the psychological and social domains, but not in the medical domain.The ASI questionnaire was completed a second time by 24 patients, after an average of 3.2 months. The improvement was significant in the M, A, D and P domains only.This study provided an overview of the methods employed in managing a sample of patients consulting an alcoholism centre in line with standards for medical, psychological and social establishments. The predominance of the social and psychological domains over the medical domain was clearly established. Relapses were common after the third month of treatment, but a remobilisation of teams made it possible to contain them. These results provide a framework for discussions on the organisation of healthcare systems and highly suggest that staff need to maintain a constant level of care throughout the treatment process.In France, care for alcoholic outpatients is provided by specialized centres which group together physicians trained in addiction problems, psychologists and social workers. These centres, the CCAA (Centre de Cure Ambulatoire en Alcoologie, or outpatient centres for the care of alcoholics), are fu

World Journal of Gastroenterology , 2008,
Abstract: AIM: To determine factors associated with fibrosis progression in hepatitis C virus (HCV)-infected patients without significant initial pathological lesions.METHODS: Seventy six untreated HCV-infected patients with initially normal liver as defined by a Knodell score ≤ 3, with 2 liver biopsies and detectable HCV-RNA were included. Markers of fibrosis progression were assessed.RESULTS: Median duration of infection and time between paired biopsies was 13 (95% CI: 1-28) and 4 (95% CI: 2-16) years respectively. Alanine-transaminase (ALT) activity was normal in 43.4% of cases. 50% demonstrated progression of the necro-inflammation and 34% of fibrosis after a median time evolution of 4 years (95% CI: 2-16). The median difference in the necro-inflammation and fibrosis score between biopsies was low, 1.5 and 0.0 respectively. Univariate analysis showed there was no difference between fibrosis activity or evolution according to genotype or viral load. A higher fibrosis progression (P = 0.03) was observed in patients with body mass index (BMI) > 25. Fibrosis progression correlated with the time interval between biopsies (P = 0.01). A significant progression of activity (1.7 vs 0.4, P < 0.05) or fibrosis (0.9 vs 0.0, P < 0.01) was observed in patients with elevated ALT. There was a significant correlation between activity progression and fibrosis progression (P = 0.003). Multivariate analysis demonstrated that fibrosis progression was associated with elevated ALT, BMI > 25 and the time interval between 2 biopsies.CONCLUSION: There is no fibrosis progression in 66% of patients without significant initial histopathological lesion. Fibrosis progression is associated with elevated ALT and BMI > 25.

Andean geology , 2011,
Abstract: this work addresses the kinematic effects of a rigid block in strike-slip systems by using analogue models. the experiments (size, behaviour of materials) were scaled down in order to represent deformation of the tested rheologic contrast conditions in deformation. two main parameters were tested: the configuration of the rigid block, changing its form and size, and the amount of displacement. the experiments evidenced the development of rotations, faults and folds along the fault trajectory, as resulting from the presence of the rigid block during the deformation. testing of diverse geometric situations may be used for comparison to strike-slip fault systems in which different lithologies and rheologic behaviour exist, for example, presence of the 'limón verde rigid core' along the domeyko fault system, just south of chuquicamata.
Influencia de un bloque rígido en un sistema de fallas de rumbo: modelamiento análogo Influence of a rigid block in a strike-slip fault system: analogue modelling

Andean Geology , 2011,
Abstract: En este trabajo se presenta un estudio de modelamiento análogo sobre la naturaleza, geometría y cinemática de la deformación a lo largo de fallas de rumbo dada la presencia de un bloque rígido en su trayectoria de deformación. Los modelos análogos están apropiadamente escalados considerando las características reológicas de los materiales que se desean contrastar en la deformación. Dos grandes parámetros fueron probados: la configuración del bloque rígido, variando su forma y tama o, y el monto del desplazamiento. Los resultados experimentales muestran el desarrollo de rotaciones, fallas y pliegues como producto de la presencia de un bloque rígido en la trayectoria de falla. Los diversos casos geométricos probados pueden ser empleados para su comparación con sistemas de fallas de rumbo en los cuales existen diferencias litológicas de comportamiento reológico diferencial, como por ejemplo el caso del 'Núcleo rígido de Limón Verde' al sur de Chuquicamata, ubicado en la trayectoria del sistema de fallas de Domeyko.

Minimum Penalized Hellinger Distance for Model Selection in Small Samples  [PDF]
Papa Ngom, Bertrand Ntep
Open Journal of Statistics (OJS) , 2012, DOI: 10.4236/ojs.2012.24045
Abstract: In statistical modeling area, the Akaike information criterion AIC, is a widely known and extensively used tool for model choice. The φ-divergence test statistic is a recently developed tool for statistical model selection. The popularity of the divergence criterion is however tempered by their known lack of robustness in small sample. In this paper the penalized minimum Hellinger distance type statistics are considered and some properties are established. The limit laws of the estimates and test statistics are given under both the null and the alternative hypotheses, and approximations of the power functions are deduced. A model selection criterion relative to these divergence measures are developed for parametric inference. Our interest is in the problem to testing for choosing between two models using some informational type statistics, when independent sample are drawn from a discrete population. Here, we discuss the asymptotic properties and the performance of new procedure tests and investigate their small sample behavior.
Relativistic Gauge Invariant Wave Equation of the Electron-Neutrino  [PDF]
Claude Daviau, Jacques Bertrand
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.511102
Abstract:

With the right and the left waves of an electron, plus the left wave of its neutrino, we write the tensorial densities coming from all associations of these three spinors. We recover the wave equation of the electro-weak theory. A new non linear mass term comes out. The wave equation is form invariant, then relativistic invariant, and it is gauge invariant under the U(1)×SU(2), Lie group of electro-weak interactions. The invariant form of the wave equation has the Lagrangian density as real scalar part. One of the real equations equivalent to the invariant form is the law of conservation of the total current.

A Wave Equation including Leptons and Quarks for the Standard Model of Quantum Physics in Clifford Algebra  [PDF]
Claude Daviau, Jacques Bertrand
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.518210
Abstract:

A wave equation with mass term is studied for all fermionic particles and antiparticles of the first generation: electron and its neutrino, positron and antineutrino, quarks u and d with three states of color and antiquarks \"\" and \"\". This wave equation is form invariant under the \"\" group generalizing the relativistic invariance. It is gauge invariant under the U(1)×SU(2)×SU(3) group of the standard model of quantum physics. The wave is a function of space and time with value in the Clifford algebra Cl1,5. Then many features of the standard model, charge conjugation, color, left waves, and Lagrangian formalism, are obtained in the frame of the first quantization.
