No Demonstrable Relationship Was Found between Alcohol Dependence and Concomitant Drug Abuse amongst Detainees in Police Custody in West Yorkshire, England  [PDF]
Remy Bahl, William P. Tormey
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.55057
Abstract:

The behavioural effects of alcohol and drug abuse may lead to arrest by the police. Individuals who abuse one substance may be at risk of developing multiple drug dependencies. Using the forensic records, data were collected on 50 successive subjects detained in police custodies across West Yorkshire, England who had gave history of alcohol addiction to a single practitioner. The degree of correlation between alcohol dependency and illicit drug usage was assessed by calculating the Spearman’s Rank coefficient. Thirty three subjects in this study did not use any illicit drugs. There was no correlation between alcohol dependency and concomitant drug abuse in this group. Spearman’s coefficient was statistically insignificant (p = 0.230). Kruskal’s Gamma, which is used for comparing ordinal data, also failed to show a significant link between the alcohol and drug group (p = 0.185). As the degree of alcohol dependency increased, co-use of other drugs decreased. Conversely as the use of stronger drugs increased, co-use with alcohol and other drugs increased. Alcohol dependency is a distinct disorder. Once alcoholism had set in, the use of other drugs falls. The forensic behavioural patterns linked alcohol with “violent disorder” and Class A drug abuse with “organised crime”. This study does not support the contention that most alcohol dependent individuals will also abuse illicit drugs.

Some Properties of a Recursive Procedure for High Dimensional Parameter Estimation in Linear Model with Regularization  [PDF]
Hong Son Hoang, Remy Baraille
Open Journal of Statistics (OJS) , 2014, DOI: 10.4236/ojs.2014.411087
Abstract: Theoretical results related to properties of a regularized recursive algorithm for estimation of a high dimensional vector of parameters are presented and proved. The recursive character of the procedure is proposed to overcome the difficulties with high dimension of the observation vector in computation of a statistical regularized estimator. As to deal with high dimension of the vector of unknown parameters, the regularization is introduced by specifying a priori non-negative covariance structure for the vector of estimated parameters. Numerical example with Monte-Carlo simulation for a low-dimensional system as well as the state/parameter estimation in a very high dimensional oceanic model is presented to demonstrate the efficiency of the proposed approach.
Psychological Sense of Community Responsibility and Diversity in Old Age: A Qualitative Study of Urban Older Adults in India  [PDF]
Nina Kavita Heggen Bahl, Ingunn Hagen
Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.57024
Abstract: The aim of the present study is to explore older adult people’s meaning of psychological sense of community (PSOC), a key element in individual and community well-being. Using thematic and discourse analytical approaches we have in an in-depth and context-sensitive way analyzed interview material from twelve urban older informants residing in the heterogenic mega-city of Mumbai. Several themes included in the samples meaning of PSOC confirm established dimensions of the concept. However, key aspects of their meaning system more closely relate to the concepts PSOC-R and diversity and demonstrate these inherent concepts as highly culturally bound and context-sensitive at a city and national level.
Croissance économique des pays émergents et géographie mondiale des pierres précieuses
Remy Canavesio
EchoGéo , 2011,
Abstract: L’évolution mondiale des activités extractives est de plus en plus dépendante de la demande des pays émergents. Les conséquences de la croissance de ces pays sur les exploitations de pierres précieuses sont complexes car le marché des gemmes a de nombreuses particularités. La demande est étroitement liée aux matrices socioculturelles de chaque pays. Par ailleurs, l’enrichissement des populations a également un impact sur la production de pierres telles que les saphirs ou les rubis. En effet, ces gemmes sont principalement extraites dans des exploitations informelles et cette activité est de moins en moins attractive pour une population dont le niveau de vie s’élève peu à peu. Dans les vastes gisements sri lankais et birmans, l’épuisement de la ressource est une autre menace. Finalement, si la croissance du marché du diamant est assurée par le Canada, la Russie et l’Australie, pour les autres gemmes, l’Afrique de l’Est est devenue le nouvel Eldorado . Dans ces pays, les contextes géologiques, économiques, politiques et sociaux sont très favorables au développement des exploitations artisanales de gemmes. Extraction activities evolution is more and more dependent on the increase of demand in the emerging countries. The consequences of this growth on the gemstone mining activities are complex. The gemstone market is very special and the demand depends on the historic and cultural situation of every country. Moreover, for precious stones like rubby and sapphire, the supply coming from this emerging country is also affected by the social and economic changes. As the small scale mining is widely held in this activity, people that are becoming richer are less interested in that kind of job. In Sri Lanka and Burma, the depletion of many deposits is an other challenge. Finally, if new diamonds deposits of Canada, Russia and Australia are supplying the growth of the diamond market, Est Africa looks like the new Eldorado for the other gemstones. Geologic, economic, social and political context of these countries are perfectly adapted for the development of new gemstone small scall mining areas.
Les sociétés militaires privées dans la lutte contre la piraterie
Catheline Remy
Pyramides : Revue du Centre d'Etudes et de Recherches en Administration Publique , 2012,
Abstract: La Somalie est au c ur de l’actualité avec la résurgence d’actes de piraterie de plus en plus spectaculaires. Le Conseil de sécurité des Nations Unies a autorisé les Etats à réprimer ces actes dans les eaux territoriales somaliennes. L’OTAN et l’Union européenne ont, sur cette base, déployé une force navale au large des c tes somaliennes. D’autres acteurs sont également présents en mer pour des activités de sécurisation. Les sociétés militaires privées profitent, en effet, de cette aubaine pour proposer leurs services aux armateurs et aux Etats. Ces sociétés offrent une variété de services allant de la consultance à des escortes armées en passant par la négociation pour la libération d’otages.L’emploi de sociétés militaires privées dans le cadre de la lutte contre la piraterie soulève des questions d’ordre juridique national et international. Le droit national de l’Etat dans lequel les activités de sécurité sont exercées précise les conditions dans lesquelles ces activités peuvent être exercées. En droit international, la Convention des Nations Unies sur le droit de la mer habilite uniquement les Etats à réprimer les actes de piraterie. Cependant, ces aspects juridiques ne semblent pas empêcher l’emploi de telles sociétés.
Laffont Pierre-Yves, Chateaux du Vivarais. Pouvoirs et peuplement en France méridionale du haut Moyen ge au XIIIe siècle
Christian Remy
Revue Archéologique du Centre de la France , 2011,
Abstract: Cet ouvrage de Pierre-Yves Laffont est la version remaniée de sa thèse, soutenue en 1998, à l’université de Lyon-2 (M.-Th. Lorcin dir.). Il examine les transformations de la société vivaroise, du monde carolingien à la féodalité. Dans ce processus, le chateau appara t comme le support essentiel de mutation et l’on sait gré à l’auteur d’avoir cherché à concilier la démarche historique et la lecture morphologique et archéologique des sites.Le Vivarais correspond grosso modo au département de l’...
Geometrical approach to SU(2) navigation with Fibonacci anyons
Remy Mosseri
Physics , 2008, DOI: 10.1088/1751-8113/41/17/175302
Abstract: Topological quantum computation with Fibonacci anyons relies on the possibility of efficiently generating unitary transformations upon pseudoparticles braiding. The crucial fact that such set of braids has a dense image in the unitary operations space is well known; in addition, the Solovay-Kitaev algorithm allows to approach a given unitary operation to any desired accuracy. In this paper, the latter task is fulfilled with an alternative method, in the SU(2) case, based on a generalization of the geodesic dome construction to higher dimension.
Two and Three Qubits Geometry and Hopf Fibrations
Remy Mosseri
Physics , 2003,
Abstract: This paper reviews recent attempts to describe the two- and three-qubit Hilbert space geometries with the help of Hopf fibrations. In both cases, it is shown that the associated Hopf map is strongly sensitive to states entanglement content. In the two-qubit case, a generalization of the one-qubit celebrated Bloch sphere representation is described.
Kac-Moody groups as discrete groups
Bertrand Remy
Mathematics , 2004,
Abstract: This survey paper presents the discrete group viewpoint on Kac-Moody groups. Over finite fields, the latter groups are finitely generated; they act on new buildings enjoying remarkable negative curvature properties. The study of these groups is shared between proving results supporting the analogy with some $S$-arithmetic groups, and exhibiting properties showing that they are new groups.
Kac-Moody groups: split and relative theories. Lattices
Bertrand Remy
Mathematics , 2002,
Abstract: In this survey article, we recall some facts about split Kac-Moody groups as defined by J. Tits, describe their main properties and then propose an analogue of Borel-Tits theory for a non-split version of them. The main result is a Galois descent theorem, i.e. the persistence of a nice combinatorial structure after passing to rational points. We are also interested in the geometric point of view, namely the production of new buildings admitting (nonuniform) lattices.
