Analyses typologiques confirmatoires. Evaluation d'une partition hypothétique issue d'une étude sémiotique
Authors: Chandon Jean-Louis , Dano Florence 
Published: March 2013

On constate qu'il est très important d'avoir des méthodes d'évaluation des partitions afin d'évaluer les résultats des analyses typologiques. Cet article développe une méthode fondée sur des critères internes et externes permettant d'estimer l'adéquation entre les partitions devant être évaluées et les données à partir desquelles elles ont été générées. La première partie présente plusieurs critères internes et externes de validation en typologie, et les solutions retenues par le logiciel Evalu-P, conçu par le premier auteur. La seconde partie illustre les étapes de validation d'une partition hypothétique en cinq classes de consommateurs, issue des résultats d'une analyse sémiotique du discours des consommateurs sur le packaging. 43 partitions pour le riz et 54 partitions pour le shampoing ont été générées en utilisant des méthodes de classification hiérarchique et de réallocation. Ces partitions empiriques ont été évaluées par rapport à la partition hypothétique en utilisant cinq critères internes et cinq critères externes de validation.

Authors: Derbaix Christian , Blondeau Sarah , Pecheux Claude 
Published: March 2013

Le but essentiel de cette recherche est la mise au point d'une échelle de mesure de l'attitude envers l'annonce (Aad) spécialement destinée à être administrée à des enfants de 8 à 12 ans. A notre connaissance, personne n'a tenté à ce jour de construire une telle échelle adaptée à un public souvent visé par la publicité, déjà à même d'sêtre soumis à un questionnement de type verbal, jouant les rôles de prescripteurs et d'acheteurs, relevant du stade opératoire concret, fréquentant l'école primaire et n'appartenant pas encore au groupe des adolescents. Après une brève synthèse de la littérature sur Aad et sur les problèmes de mesure spécifiques aux enfants, nous relatons les différentes étapes du paradigme de Churchill appliqué à notre cas. Au terme d'une étude pilote menée auprès de 481 enfants, et surtout au terme de six recueils de données conduits auprès de plus de 1 000 enfants, nous proposons un outil de mesure fiable et valide de Aad adapté à notre jeune public, outil unidimensionnel fait d'une seule facette matérialisée par 6 propositions. En conclusion, nous précisons ce qu'est Aad pour ces enfants.
Disrupted Response Inhibition Toward Facial Anger Cues in Children With Attention-Deficit Hyperactivity Disorder (ADHD)
Authors: Köchel Angelika , Leutgeb Verena , Schienle Anne 
Published: March 2013

This event-related potential study focused on neural correlates of inhibitory affective control in attention-deficit hyperactivity disorder (ADHD). Sixteen boys with ADHD and 16 healthy boys underwent an emotional Go/NoGo task with pictures of facial expressions from the categories anger, sadness, happiness, and neutral. The participants were instructed to execute or withhold a motor response to specific emotions. Patients relative to controls displayed a severe impairment in response inhibition toward anger cues, which was accompanied by a reduced P300 amplitude (positive voltage deflection about 300 ms after picture onset). The control group showed a P300 differentiation of the affective categories that was absent in the ADHD group. The pronounced anger-processing deficit in ADHD patients might be linked to their interpersonal difficulties and should be addressed in psychotherapy.

Published: March 2013

Raman spectroscopy was used to monitor the curing process of a benzoxazine monomer. The reaction follows an autocatalytic mechanism. The autocatalytic model described in Kamal equation was employed. The activation energy and the pre-exponential factor were determined as: Ea = 60.52 kJ mol−1 and A = 6.09 × 105 min−1. The overall reaction order was found to be 1.731 ( n = 1.078; m = 0.653). The kinetic model characterized by these values is in good agreement with the experimental values.

Authors: Park Gi Heon , Jung Sung Taek , Chung Jae Yoon , Park Hyeong Won , Lee Dong Hyun 
Published: March 2013

Background: Polydactyly of the fifth toe is the most common congenital malformation of the forefoot, and no consensus has been reached as to which toe component should be excised or by which surgical technique. The purpose of this study was to evaluate the results of the operative treatment of postaxial polydactyly and to offer treatment guidelines. Method: We retrospectively reviewed the details of 27 patients with postaxial polydactyly (36 feet) treated from September 2004 to March 2010. To select the dominant toe of postaxial polydactyly, we evaluated the morphological and radiological configurations. To excise the medial toe, we treated the polydactyly by dorsal rectangular flap and a full-thickness inguinal skin graft. To excise the lateral toe, we treated the polydactyly by racket-shape incision. Patient satisfaction indices were evaluated on the basis of responses to the PSQ-10 patient satisfaction questionnaire and clinical outcomes. Result: Overall surgical outcomes were satisfactory with the exception of 2 cases of skin graft problems. Eighteen of the 36 reconstructed toes were smaller than the normal toes, but valgus deformity was observed in only 3 cases. Conclusion: The described medial toe excision technique and the devised toe selection algorithm were able to satisfy functional and cosmetic requirements. Level of Evidence: Level IV, retrospective case series.
Social work practice in the chronic care model: Chronic illness and disability care
Authors: Findley Patricia A 
Published: March 2013

Summary Maintaining good quality of life and health in face of living and/or aging with a chronic illness and/or disability can be challenging. The health care and related education and training of these individuals to become proactive partners in their ongoing care is the cornerstone of most chronic care models. Findings Social workers are not specifically mentioned in most chronic care models. However, as the health and social care processes can become complicated if the individual has barriers to partnering roles necessitated by chronic care models, a role for the social worker should be more clearly defined. Examination and application of the ecosystems perspective defines a clear role for social work to work collaboratively with other health professionals within a chronic care model. Application This paper explores how social work’s ecosystems model can interface with Wagner’s Chronic Care Model to fill the void that some individuals may experience in seeking and maintaining care to provide a useful framework to facilitate interventions within that model.

The Stakeholders Human resource and organization development (HROD) scholars who would use the DLOQ in studies of organizational culture need accurate information about the instrument. HROD practitioners who plan to use the instrument also need information about its utility and reliability to share with stakeholders and to ensure that high quality data will inform their interventions.
Efficacy and safety of oral prucalopride in women with chronic constipation in whom laxatives have failed: an integrated analysis
Authors: Tack Jan , Quigley Eamonn , Camilleri Michael , Vandeplassche Lieve , Kerstens René 
Published: March 2013

BackgroundPrucalopride is a selective, high‐affinity, 5‐hydroxytryptamine (serotonin) type 4 (5‐HT4) receptor agonist with gastrointestinal prokinetic activities. This integrated analysis of data from three double‐blind phase III trials (ClinicalTrials.gov: NCT00488137, NCT00483886, NCT00485940) compared the efficacy and safety of prucalopride 2 mg once daily in women with chronic constipation [≤2 spontaneous complete bowel movements (SCBM) per week] in whom laxatives had failed to provide adequate relief with that in the all‐patient (AP) population of men and women with chronic constipation who had or had not obtained relief from laxatives.MethodsPatients received prucalopride 2 mg or placebo once‐daily for 12 weeks. Efficacy endpoints included an average of ≥3 SCBM/week and average increases of ≥1 SCBM/week and ≥1 SBM/week over this period. A response on any of these three endpoints was considered to be clinically relevant, and an overall response rate was derived for patients satisfying any of these endpoints.ResultsOf the AP population (n  = 1318), 936 were women in whom laxatives had failed to provide adequate relief (WLF). More patients on prucalopride 2 mg than placebo had an average of ≥3 SCBM/week (AP 24.4 vs 11.0%; WLF 24.7 vs 9.2%), an average increase of ≥1 SCBM/week (AP 43.5 vs 24.8%; WLF 44.2 vs 22.6%), and an average increase of ≥1 SBM/week (AP 66.7 vs 38.4%; WLF 68.3 vs 37.0%) (all p  < 0.001). Significant differences from placebo were evident in week 1 and sustained thereafter. Overall response rates in the AP and WLF populations, respectively, were 69.7 and 71.0% with prucalopride 2 mg and 44.5 and 41.6% with placebo (p  < 0.001). Early (weeks 1–4) response predicted ultimate response over time. Common (>10%) adverse events were abdominal pain, nausea, diarrhoea, and headache.ConclusionsPrucalopride 2 mg once daily is effective in WLF. The efficacy and safety profile observed in WLF was similar to that in the total evaluated population of patients with chronic constipation who had or had not obtained adequate relief from laxatives.
Kleberite, Fe3+Ti6O11(OH)5, a new ilmenite alteration product, from Königshain, northeast Germany
Authors: Grey I. E. , Steinike K. , MacRae C. M. 
Published: March 2013

AbstractKleberite, ideally Fe3+Ti6O11(OH)5, is a new mineral (IMA 2012-023) from Tertiary sands at Königshain, Saxony, northeast Germany. It is also found in heavy mineral sands from the Murray Basin, southeast Australia and at Kalimantan, Indonesia. It occurs as rounded anhedral to euhedral translucent grains, 0.04 0.3 mm across, which are generally red-brown, but grade to orange with decreasing iron content. Associated minerals include ilmenite, pseudorutile, 'leucoxene', tourmaline and spinel. The density measured by pycnometry is 3.28 g cm-3, which is lower than the calculated density of 3.91 g cm-3, due to intragrain porosity which is not penetrated by the immersion fluid. The intragrain pores, of median diameter 18 nm, are partially filled with impurity phases including kaolinite, diaspore and quartz. Kleberite grains have a uniaxial (–) character, but localized regions are weakly biaxial (–) with 2V close to zero. The mean refractive index, calculated from reflectance measurements, is 2.16(3). The mean empirical formula from electron-microprobe analyses of 15 Königshain kleberite grains is Fe3+1.01Mg0.06Ti6O11.2(OH)4.8[Al0.59Si0.31P0.04O1.60·1.8H2O], where the formula element in square brackets represents impurities in the pores. Kleberite forms over a compositional range with [Ti]/[Fe + Ti] atomic ratios from 0.8–0.9. It has monoclinic symmetry, P21/c, with a = 7.537(1), b = 4.5795(4), c = 9.885(1) Å , β = 131.02(1)°. The six strongest lines in the powder X-ray diffraction (XRD) pattern [listed as d in Å (I)] are as follows: 1.676(100), 2.170(82), 2.466(27), 1.423(22), 3.933(8), 2.764(9). The structure was refined by the Rietveld method on powder XRD data to Rp = 6.3, Rwp = 8.1, RB = 4.0. Kleberite is isostructural with tivanite; their structural formulae are [Ti4+3□][Ti4+3Fe3+]O11 (OH)5 and [Ti4+4][V3+4]O12(OH)4, respectively. Kleberite has dominant Ti4+ in place of V3+ in the M(2) metal-atom site. The related mineral pseudorutile, [Ti4][(Fe3+,Ti)4](O,OH)16, with Fe3+ > Ti4+ has dominant Fe3+ in this site. Kleberite grains from different localities commonly contain residual MgO-rich ferrian ilmenite. The chemical and physical relationships between the ilmenite and coexisting kleberite are used to evaluate different alteration mechanisms involving selective leaching of divalent oxides from ilmenite and pseudomorphic replacement reactions, respectively.
Lead-bearing phyllotungstite from the Clara mine, Germany with an ordered pyrochlore–hexagonal tungsten bronze intergrowth structure
Authors: Grey I. E. , Mumme W. G. , MacRae C. M. 
Published: March 2013

AbstractLead-bearing phyllotungstite from the Clara mine in the central Black Forest, Germany has a formula (Cs0.41)Na0.14K0.05Pb2+2.01Ca0.26[W6+10.87Fe3+3.13O35.75(OH)6.25](O(H2O)3). X-ray diffraction patterns exhibit pseudohexagonal symmetry, but refinement of single-crystal synchrotron data has shown that the true symmetry is orthorhombic, Cmcm, with a = 7.298(1), b = 12.640(2), c = 19.582(4) Å, and that the pseudohexagonal character is due to submicrometre-scale cyclical twinning by rotation about the pseudohexagonal c axis. The structure can be described in terms of an ordered intergrowth, parallel to (001), of (111)py blocks with pyrochlore-type structures, which are ~6 Å in width, and two-layer wide regions with a hexagonal tungsten bronze (HTB) type structure. Caesium atoms occupy 18-coordinate cavities in the HTB regions, and H2O molecules occupy Φ sites in the A2B2O6Φ pyrochlore blocks. The lowering of symmetry from hexagonal to orthorhombic is due to partial ordering of W and Fe in the octahedral B sites and of Pb and vacancies in the A sites of the pyrochlore blocks. The ideal formula for the intergrowth structure (with no vacancies) is C 2A10[B14(O,OH)42]Φ4, where C is the cavity site in the HTB slabs. The mineral has only 21% occupancy of the C site and 25% occupancy of the A site, but full occupancy of the Φ site. There may be some mixing of Cs and H2O between the C and Φ sites.

AbstractBobmeyerite, Pb4(Al3Cu)(Si4 O12)(S0.5Si0.5O4)(OH)7 Cl(H2O)3, is a new mineral from the Mammoth - Saint Anthony mine, Tiger, Pinal County, Arizona, USA. It occurs in an oxidation zone assemblage attributed to progressive alteration and crystallization in a closed system. Other minerals in this assemblage include atacamite, caledonite, cerussite, connellite, diaboleite, fluorite, georgerobinsonite, hematite, leadhillite, matlockite, murdochite, phosgenite, pinalite, quartz, wulfenite and yedlinite. Bobmeyerite occurs as colourless to white or cream-coloured needles, up to 300 m m in length, that taper to sharp points. The streak is white and the lustre is adamantine, dull or silky. Bobmeyerite is not fluorescent. The hardness could not be determined, the tenacity is brittle and no cleavage was observed. The calculated density is 4.381 g cm-3. Bobmeyerite is biaxial (-) with α ≈ β = 1.759(2), γ = 1.756(2) (white light), it is not pleochroic; the orientation is X = c; Y or Z = a or b. Electron-microprobe analyses provided the empirical formula Pb3.80Ca0.04Al3.04Cu2+0.96Cr3+0.13Si4.40S0.58O24.43Cl1.05F0.52H11.83. Bobmeyerite is orthorhombic (pseudotetragonal), Pnnm with unit-cell parameters a = 13.969(9), b = 14.243(10), c = 5.893(4) Å, V = 1172.5(1.4) Å3 and Z = 2. The nine strongest lines in the X-ray powder diffraction pattern, listed as [dobs (Å)(I)(hkl)], are as follows: 10.051(35)(110); 5.474(54)(011,101); 5.011(35)(220); 4.333(43)(121,211); 3.545(34)(040,400); 3.278(77)(330,231,321); 2.9656(88)(141,002,411); 2.5485(93)(051,222,501); 1.873(39)(multiple). Bobmeyerite has the same structural framework as cerchiaraite and ashburtonite. In the structure, which refined to R1 = 0.079 for 1057 reflections with F > 4σF, SiO4 tetrahedra share corners to form four-membered Si4O12 rings centred on the c axis. The rings are linked by chains of edge-sharing AlO6 octahedra running parallel to [001]. The framework thereby created contains large channels, running parallel to [001]. The Cl site is centred on the c axis alternating along [001] with the Si4O12 rings. Two non-equivalent Pb atoms are positioned around the periphery of the channels. Both are elevencoordinate, bonding to the Cl atom on the c axis, to eight O atoms in the framework and to two O (H2O) sites in the channel. The Pb atoms are off-centre in these coordinations, as is typical of Pb2+ with stereo-active lone-electron pairs. A (S, Si, Cr)O4 group is presumed to be disordered in the channel. The name honours Robert (Bob) Owen Meyer, one of the discoverers of the new mineral.

AbstractShimazakiite occurs as greyish white aggregates up to 3 mm in diameter. Two polytypes, shimazakiite-4M and shimazakiite-4O, have been identified, the former in nanometre-sized twin lamellae and the latter in micrometre-sized lamellae. Shimazakiite was discovered in an irregular vein in crystalline limestone near gehlenite-spurrite skarns at Fuka mine, Okayama Prefecture, Japan. Associated minerals include takedaite, sibirskite, olshanskyite, parasibirskite, nifontovite, calcite and an uncharacterized hydrous calcium borate. The mineral is biaxial (–), with the following refractive indices (at 589 nm): α = 1.586(2), β = 1.650(2), γ = 1.667(2) and 2Vcalc = 53º [shimazakiite-4M]; and α = 1.584(2), β = 1.648(2), γ = 1.670(2) and 2Vcalc = 54.88º [shimazakiite-4O]. Quantitative electronmicroprobe analyses (means of 28 and 25 determinations) gave the empirical formulae Ca2B1.92O4.76(OH)0.24 and Ca2B1.92O4.76(OH)0.24 for shimazakiite-4M and shimazakiite-4O, respectively. The crystal structure refinements: P21/c, a = 3.5485(12), b = 6.352(2), c = 19.254(6) Å , β = 92.393(13)°, V = 433.6(3) Å3 [for shimazakiite-4M]; and P212121, a = 3.55645(8), b = 6.35194(15), c = 19.2534(5) Å , V = 434.941(18) Å3[for shimazakiite-4O], converged into R1 indices of 0.1273 and 0.0142, respectively. The crystal structure of shimazakiite consists of a layer containing B2O5 units (two near-coplanar triangular corner-sharing BO3 groups) and 6- and 7-coordinate Ca atoms. Different sequences in the c direction of four layers are observed in the polytypes. The five strongest lines in the powder-diffraction pattern [listed as d in Å (I)(hkl)] are: 3.02(84)(022); 2.92(100)(10) 2.81(56)(104); 2.76(32)(113); 1.880(32)(11,12,126,118) [for shimazakiite-4M]; and 3.84(33)(014); 3.02(42)(022); 2.86(100)(104); 2.79(29)(113); 1.903(44)(126,118) [for shimazakiite-4O].

AbstractŠtěpite, tetragonal U(AsO3 OH)2(H2O)4 (IMA 2012-006), is the first natural arsenate of tetravalent uranium. It occurs in the Geschieber vein, Jáchymov ore district, Western Bohemia, Czech Republic, as emerald-green crystalline crusts on altered arsenic. Associated minerals include arsenolite, běhounekite, claudetite, gypsum, kaatialaite, the new mineral vysokýite (IMA 2012-067) and a partially characterized phase with the formula (H3O)+2(UO2)2(AsO4)2˙6H2O. Štěpite typically forms tabular crystals with prominent {001} and {010} faces, up to 0.6 mm in size. The crystals have a vitreous lustre and a grey to greenish grey streak. They are brittle with an uneven fracture and a very good cleavage on (001). Their Mohs hardness is about 2. Štěpite is not fluorescent in either short-wave or long-wave ultraviolet light. It is biaxial (–) with refractive indices (at 590 nm) of α = 1.636(2), β = 1.667(3), γ = 1.672(2) and 2Vobs < ~5°, anomalous greyish to pale yellow interference colours, and no pleochroism. The composition is as follows: 0.12Na2O, 50.19 UO2, 0.04SiO4, 0.09 P2O5, 0.93 As2O5, 1.95 SO3, 16.41 H2O; total 107.90 wt.%, yielding an empirical formula (based on 12 O a. p. f. u.) of (U1.01Na0.02)Σ1.03[(AsO3OH)1.82 (PO3OH)0.04(SO4)0.13(SiO4)0.01]Σ 2.00˙4H2O. Štěpite is tetragonal, crystallizing in space group I41/acd, with a = 10.9894(1), c = 32.9109(6) Å, V = 3974.5(1) Å3, Z = 16 and Dcalc = 3.90 g cm-3. The six strongest peaks in the X-ray powder-diffraction pattern [dobs in Å (I) (hkl)] are as follows: 8.190(100)(004), 7.008(43)(112), 5.475(18)(200), 4.111(16)(008), 3.395(20)(312,217), 2.1543(25)(419). The crystal structure of šteěpite has been solved from singlecrystal X-ray diffraction data by the charge-flipping method and refined to R1 = 0.0353 based on 1434 unique observed reflections, and to wR2 = 0.1488 for all 1523 unique reflections. The crystal structure of štšpite consists of sheets perpendicular to [001], made up of eight-coordinate uranium atoms and hydroxyarsenate 'tetrahedra'. The ligands surrounding the uranium atom consist of six oxygen atoms which belong to the hydroxyarsenate groups and two oxygen atoms which belong to interlayer H2 O molecules. Each UO8 polyhedron is connected to five other U polyhedra via six AsO3OH groups. Adjacent electroneutral sheets, of composition [U4+(AsO3OH)22-]0, are linked by hydrogen bonds involving H2 O molecules in the interlayers and OH groups in the sheets. The new mineral is named in honour of Josef Štěp (1863–1926), a Czech mining engineer and 'father' of the world's first radioactive spa at Jáchymov.
