Solving ambiguities in contig assembly of Idiomarina loihiensis L2TR chromosome by in silico analyses.

Nucleotide composition analyses of bacterial genomes such as cumulative GC skew highlight the atypical, strongly asymmetric architecture of the recently published chromosome of Idiomarina loihiensis L2TR, suggesting that an inversion of a 600-kb chromosomal segment occurred. The presence of 3.4-kb inverted repeated sequences at the borders of the putative rearrangement supports this hypothesis. Reverting in silico this segment restores (1) a symmetric chromosome architecture; (2) the co-orientation of transcription of all rRNA operons with DNA replication; and (3) a better conservation of gene order between this chromosome and other gamma-proteobacterial ones. Finally, long-range PCRs encompassing the ends of the 600-kb segment reveal the existence of the reverted configuration but not of the published one. This demonstrates how cumulative nucleotide-skew analyses can validate genome assemblies.

Décrire la nature de la relation entraîneur-athlète entre des entraîneurs masculins et leurs équipes de volleyball féminin de différents niveaux de compétition

But : Ce projet de recherche a comme objectif principal de mieux comprendre diverses facettes de la relation entraîneur-entrainée. Cette relation entre un entraîneur masculin et une athlète féminine en volleyball sera observée selon trois niveaux de compétition des athlètes – secondaire, collégial et universitaire. Trois aspects seront étudiés à travers les questions posées dans cette recherche : (1) Est-ce que la perception que les athlètes ont de la relation entraîneur-entraîné est différente selon le niveau de compétition de l’athlète? (2) Existe-il des différences dans la nature de la relation à l’intérieur d’un même niveau? (3) Est-ce que le nombre d’années qu’une athlète a passé avec le même entraîneur affecte la qualité de la relation?. Méthodologie : Évoluant sur le circuit québécois, les six équipes de volleyball et leur entraîneur respectif représentent l’échantillon de la présente étude. Les tests utilisés afin de réaliser les analyses univariées et bivariées de cette étude sont : le Test de Welch, les corrélations de Pearson ainsi que les tests post-hoc de Games-Howell. Résultats : (1) Les athlètes du secondaire partagent une relation de meilleure qualité avec leur entraîneur que celles du cégep et de l’université. (2) Dans un même niveau de compétition, ce qui différencie la qualité de la relation est : le rôle de la joueuse dans son équipe ainsi que le nombre de sports organisés dans lesquels elle participe (relations proportionnelles). (3) Une relation inverse existe entre le nombre d’années vécues par la dyade entraîneur-athlète et la qualité de la relation.

Campaigning Against Europe? The Role of Euroskeptic Fringe and Mainstream Parties in the 2009 European Parliament Election

In this article, we analyze political parties' campaign communication during the 2009 European Parliamentary election in 11 countries (Austria, Bulgaria, Czech Republic, Germany, Hungary, The Netherlands, Poland, Portugal, Spain, Sweden, and the UK). We study which types of issues Euroskeptic fringe and Euroskeptic mainstream parties put on their campaign agendas and the kind and extent of EU opposition they voice. Further, we seek to understand whether Euroskeptic and non-Euroskeptic parties co-orient themselves toward each other within their national party systems with regard to their campaigns. To understand the role of Euroskeptic parties in the 2009 European Parliamentary elections, we draw on a systematic content analysis of parties' posters and televised campaign spots. Our results show that it is Euroskeptic parties at the edges of the political spectrum who discuss polity questions of EU integration and who most openly criticize the union. Principled opposition against the project of EU integration, however, can only be observed in the UK. Finally, we find indicators for co-orientation effects regarding the tone of EU mobilization: In national political environments where Euroskeptic parties strongly criticize the EU, pro-European parties at the same time publicly advance pro-EU positions.

The application of cognitive orientation to daily occupational performance (CO-OP) with children 5-7 years with developmental coordination disorder

There has been an increase in the use of cognitive frameworks in occupational therapy with children with developmental coordination disorder (DCD). Investigations into the utility of one such cognitive approach, namely Cognitive Orientation to (daily) Occupational Performance (CO-OP), with children with DCD have shown the intervention to be effective with children over 7 years. However, there has been limited research into its utility with younger children. This paper presents two case studies to demonstrate the use of CO-OP with children aged 5-7 years. Two boys with DCD engaged in 10 sessions of CO-OP. These younger children were found to be able to use the global framework (Goal, Plan, Do, Check) to improve their task performance, to develop plans using domain-specific strategies and to engage in checking strategies. Issues relating to attention, motivation and goal setting are discussed in the context of the two case studies.

Structural, electrical and magnetic studies of Co:SnO2 and (Co,Mo):SnO2 films prepared by pulsed laser deposition

Here we report on the structural, optical, electrical and magnetic properties of Co-doped and (Co,Mo)-codoped SnO2 thin films deposited on r-cut sapphire substrates by pulsed laser deposition. Substrate temperature during deposition was kept at 500 degrees C. X-ray diffraction analysis showed that the undoped and doped films are crystalline with predominant orientation along the [1 0 1] direction regardless of the doping concentration and doping element. Optical studies revealed that the presence of Mo reverts the blue shift trend observed for the Co-doped films. For the Co and Mo doping concentrations studied, the incorporation of Mo did not contribute to increase the conductivity of the films or to enhance the ferromagnetic order of the Co-doped films.

Influence of the substrate on structure and magnetic properties of Co-N thin films

Cubic cobalt nitride films were grown onto different single crystalline substrates Al2O3 (0 0 0 1) and (1 1 View the MathML source 0), MgO (1 0 0) and (1 1 0) and TiO2 (1 0 0) and (1 1 0). The films display low atomic densities compared with the bulk material, are ferromagnetic and have metallic electrical conductivity. X-ray diffraction and X-ray absorption fine structure confirm the cubic structure of the films and with RBS results indicate that samples are not homogeneous at the microscopic scale, coexisting Co4+xN nitride with nitrogen rich regions. The magnetization of the films decreases with increase of the nitrogen content, variation that is shown to be due to the decrease of the cobalt density, and not to a decrease of the magnetic moment per cobalt ion. The films are crystalline with a nitrogen deficient stoichiometry and epitaxial with orientation determined by the substrate.

High-frequency linkage of co-expressing T-DNA in transgenic Arabidopsis thaliana transformed by vacuum-infiltration of Agrobacterium tumefaciens

The efficiency of co-expression and linkage of distinct T-DNAs present in separate Agrobacterium tumefaciens was analysed in Arabidopsis thaliana transformed by the vacuum infiltration method. Co-expression was monitored by the synthesis of three bacterial proteins involved in the production of polyhydroxybutyrate (PHB) in the plastids. Out of 80 kanamycin-resistant transgenic plants analysed, 13 plants were co-transformed with the two distinct T-DNAs and produced PHB. Of those, 7 lines had a kanamycin-resistance segregation ratio consistent with the presence of a single functional insert. Genetic linkage between the distinct T-DNAs was demonstrated for all 13 PHB-producing lines, while physical linkage between the distinct T-DNAs was shown for 12 out of 13 lines. T-DNAs were frequently linked in an inverted orientation about the left borders. Transformation of A. thaliana by the co-infiltration of two A. tumefaciens containing distinct T-DNAs is, thus, an efficient approach for the integration and expression of several transgenes at a single locus. This approach will facilitate the creation and study of novel metabolic pathways requiring the expression of numerous transgenes.

Construire sa vie (Life designing): Un paradigme pour l'orientation au 21e siècle

La nouvelle organisation sociale du travail du début du 21e siècle pose une série de questions et lance de nombreux défis aux spécialistes de l'accompagnement en orientation professionnelle. Compte tenu de la mondialisation du conseil en orientation, c'est dans un cadre international que nous avons décidé d'aborder ces questions, puis de formuler des réponses potentiellement innovantes. Cette approche permet d'éviter les difficultés que soulève la création de modèles et de méthodes dans un pays donné en tentant ensuite de les exporter dans d'autres, où ils doivent être adaptés pour être utilisés. Cet article présente le premier résultat tangible de cette collaboration : un modèle et des méthodes d'accompagnement des personnes. Le modèle « Construire sa vie », destiné à des interventions d'accompagnement en orientation se fonde sur cinq présupposés concernant les personnes et leur vie professionnelle : des possibilités liées aux contextes, des processus dynamiques, une progression non linéaire, des perspectives multiples et des configurations individuelles. En partant de ces présupposés, nous avons bâti un modèle en contexte, se réclamant de l'épistémologie du constructionnisme social, reconnaissant en particulier que les connaissances et l'identité d'un individu sont le produit d'interactions sociales et que le sens est co-construit, via la médiation du discours. Le cadre général « construire sa vie » s'appuie sur les théories de la construction de soi (Guichard, 2005) et de la construction des parcours professionnels (Savickas, 2005), qui décrivent les conduites d'orientation et leurs développements. Ce cadre concerne toute la vie, il est holiste, tient compte des contextes et est préventif.

The Interplay between Market Orientation and Entrepreneurial Orientation - Empirical Evidence from SMEs

The purpose of this thesis is to investigate how the dimensions of market orientation and entrepreneurial orientation are carried out in small and medium-sized enterprises (SME). In addition, the research aims to answer how these strategic orientations are apparent in SMEs, how the orientations co-vary, and how the dimensions of orientations are carried out in successful SMEs. The qualitative case study was participated by 16 SMEs. The research sample was gathered trough face-to-face interviews, consisting of Likert scale statements and open-ended questions. The main restriction of implementing market and entrepreneurial orientations in SMEs were scarce resources. Thus, the enterprises were required to make trade-offs between the different dimensios of orientations. Risk-aversive enterprises had emphasis on reactive customer orientation whereas, willing to take risks was generally related to proactiveness. Proactive enterprises utilized interfunctional coordination, and innovativeness was supported by value network coordination. The majority of the successful enterprises were growth-oriented, aiming to be technologial leaders in their industries. The successful firms placed similar emphasis on customer and product orientation.

Rectangular Dielectric Resonator Antenna on a Conductor-backed Co-planar

In this paper, we present an effective excitation of a reelangular dielectric resonator antennas (DRA) with a conductor-hacked coplanar waveguide (CB-CPW). The radiation and resonance characteristics are found to van,, depending on the orientation of the DR on doe coplanar feed line. The effect of finite and infinite ground planes of CB-CPIV on the radiation characteristics of the rectangular DRA is studied. The orientation and position of the DR are optimized for maximum gain and bandwidth. The optimized antenna ,geometry offers --10.46 dBi gain and 7.5% bandwidth with low cross-polar radiation characteristics

Homoleptic Diphosphacyclobutadiene Complexes [M(η4-P2C2R2)2]x− (M=Fe, Co; x=0, 1)

The preparation and comprehensive characterization of a series of homoleptic sandwich complexes containing diphosphacyclobutadiene ligands are reported. Compounds [K([18]crown-6)(thf)2][Fe(hapto4-P2C2tBu2)2] (K1), [K([18]crown-6)(thf)2][C(h4-P2C2tBu2)2] (K2), and [K([18]crown-6)(thf)2][Co(hapto4-P2C2Ad2)2] (K3, Ad=adamantyl) were obtained from reactions of [K([18crown-6)(thf)2][M(hapto4-C14H10)2] (M=Fe, Co) with tBuCP (1, 2), or with AdCP (3). Neutral sandwiches [M(hapto4-P2C2tBu2)2] (4: M=Fe 5: M=Co) were obtained by oxidizing 1 and 2 with [Cp2Fe]PF6. Cyclic voltammetry and spectro-electrochemistry indicate that the two [M(hapto4-P2C2tBu2)2]-/[M(hapto4-P2C2tBu2)2] moieties can be reversibly interconverted by one electron oxidation and reduction, respectively. Complexes 1–5 were characterized by multinuclear NMR, EPR (1 and 5), UV/Vis,and Moessbauer spectroscopies (1 and 4), mass spectrometry (4 and 5), and microanalysis (1–3). The molecular structures of 1–5 were determined by using X-ray crystallography. Essentially D2d-symmetric structures were found for all five complexes, which show the two 1,3-diphosphacyclobutadiene rings in a staggered orientation. Density functional theory calculations revealed the importance of covalent metal–ligand pi bonding in 1–5. Possible oxidation state assignments for the metal ions are discussed.
