Authors: Chimenti Ruth L. , Tome Joshua , Hillin Cody D. , Flemister Adolph S. , Houck Jeff 
Published: February 2014

Study Design Cross-sectional laboratory study. Objective To compare single-limb heel-rise performance and foot-ankle kinematics between persons with stage 2 adult-acquired flat foot deformity (AAFD) and healthy controls. Background The inability to perform a single-limb heel rise is considered a positive functional diagnostic test for AAFD. However, which foot motions contribute to poor performance of this task are not known. Methods Fifty individuals participated in this study, 20 with stage 2 AAFD (mean ± SD age, 57.6 ± 11.3 years), and 15 older participants (age, 56.8 ± 5.3 years) and 15 younger participants (age, 22.2 ± 2.4 years) without AAFD as control groups. Forefoot (sagittal plane) and rear foot (sagittal and frontal planes) kinematics were collected using a 3-D motion analysis system. Heel-rise performance (heel height) and kinematics (joint angles, excursions) were evaluated. One-way and 2-way analyses of variance were used to examine differences in heel-rise performance and kinematics between groups. Results Individuals with AAFD and older controls demonstrated lower heel-rise height than those in the younger control group (P<.001). Persons with AAFD demonstrated higher degrees of first metatarsal dorsiflexion (P<.001), lower ankle plantar flexion (P<.001), and higher subtalar eversion (P = .027) than those in the older control group. Persons with AAFD demonstrated lower ankle excursion (P<.001) and first metatarsal excursion (P<.001) than those in the older control group, but no difference in subtalar excursion (P = .771). Conclusion Persons with stage 2 AAFD did not achieve sufficient heel height during a single-leg heel rise. Both forefoot and rear foot kinematics in the sagittal plane, as opposed to the frontal plane, contributed to the lower heel height in participants with stage 2 AAFD. Older controls demonstrated lower heel-rise height than younger controls, indicating that clinical expectations of heel-rise performance may need to be adjusted for age.

Published: February 2014

La piraterie et l’insécurité maritime constituent des menaces persistantes à la stabilité et à l’exercice des activités marines des États riverains des côtes en général et ceux du Golfe de Guinée en particulier. Comment expliquer la recrudescence de ce phénomène depuis quelques années ? Au regard de son ampleur, aucun pays de la région ne peut à lui seul résoudre le problème de l’insécurité maritime. Quelles approches de solutions préconisent les différents acteurs internationaux, régionaux et nationaux, face à ce fléau ?
Les politiques publiques en faveur des citoyens à l'étranger : la gestion de la souffrance des migrants mexicains
Authors: Lestage Françoise 
Published: February 2014

Au Mexique, depuis la fin des années 1990, les gouvernements de l’État fédéral et des États régionaux mexicains ont mis en place des politiques publiques pour aider financièrement et administrativement les migrants mexicains aux États-Unis et leurs familles dans les démarches d’une vie quotidienne transnationale. Cet article postule qu’une partie importante de ces aides constitue un système structuré d’assistance que l’auteur qualifie de « gestion publique de la souffrance en migration ». Ce système d’aide a des fonctions spécifiques, notamment celle de maintenir les migrants dans le corps politique de leur pays d’origine. Il a aussi des effets sur la conception de la nation et du citoyen au Mexique, en particulier parce qu’il fait des migrants résidant hors du pays des bénéficiaires de politiques publiques spécifiques.
Ligation of Surface Ig by Gut-Derived Antigen Positively Selects Chicken Bursal and Peripheral B Cells

Published: February 2014

Abstract
In many mammals and birds, B cell lymphopoiesis takes place in GALT, such as the avian bursa of Fabricius. Although BCR expression is sufficient for bursal colonization, the role of BCR ligation in the later stages of bursal B cell lymphopoiesis remains elusive. To address this directly, we introduced a surface Ig–related construct with defined Ag specificity containing the Ag-binding portion of a lamprey variable lymphocyte receptor specific for PE fused to a truncated chicken μ-chain (VLRPETμ) into developing chick embryos. VLRPETμ expression supports bursal follicle colonization, clonal expansion, and Ig V gene diversification. VLRPETμ-expressing B cells migrate to the periphery in the absence of the Ag starting from day 18 of embryogenesis. VLRPETμ-expressing B cells declined rapidly in the bursa and periphery in the absence of Ag after hatch; however, intrabursal injection of PE prolonged survival of VLRPETμ+ bursal and peripheral B cells. Intrabursal introduction of Ag increased emigration of short-lived LT2+ B cells. Peripheral VLRPETμ+ B cells were maintained following intrabursal PE application and contained both short-lived LT2+ and long-lived LT2− B cells. In the chicken bursa, the later stages of B cell development occur in the presence of gut-derived Ag; therefore, we conclude that Ag-mediated ligation of BCR in bursal B cells acts to positively select bursal B cells into both short-lived and long-lived peripheral B cell populations.
Fast Exponential Time Integration for Pricing Options in Stochastic Volatility Jump Diffusion Models
Authors: Pang Hong-Kui , Sun Hai-Wei 
Published: February 2014

AbstractThe stochastic volatility jump diffusion model with jumps in both return and volatility leads to a two-dimensional partial integro-differential equation (PIDE). We exploit a fast exponential time integration scheme to solve this PIDE. After spatial discretization and temporal integration, the solution of the PIDE can be formulated as the action of an exponential of a block Toeplitz matrix on a vector. The shift-invert Arnoldi method is employed to approximate this product. To reduce the computational cost, matrix splitting is combined with the multigrid method to deal with the shift-invert matrix-vector product in each inner iteration. Numerical results show that our proposed scheme is more robust and efficient than the existing high accurate implicit-explicit Euler-based extrapolation scheme.
An Artificial Boundary Condition for a Class of Quasi-Newtonian Stokes Flows
Authors: Liu Baoqing , Chen Qing , Du Qikui 
Published: February 2014

AbstractAn artificial boundary condition method, derived in terms of infinite Fourier series, is applied to solve a class of quasi-Newtonian Stokes flows. Based on the natural boundary reduction involving an artificial condition on the artificial boundary, the coupled variational problem and its numerical solution are obtained. The unique solvability of the continuous and discrete formulations are discussed, and the error analysis for the problem is also considered. Finally, an a posteriori error estimate for the corresponding problem is provided.

Published: February 2014

Introduction: Hand skills are essential for children's occupational performance. The Assessment of Children's Hand Skills is a new assessment that utilizes naturalistic observations to capture children's actual hand-skill performance in everyday contexts. This study aimed to explore intra- and inter-rater reliability of the assessment based on video recordings, which are different from original naturalistic observations. Method: Two raters scored video recordings of 54 hand-skill activities performed by 12 children with developmental disabilities, twice in 2 weeks. Intra- and inter-rater reliability was examined at the individual hand-skill item scores, activity scores, and children's composite scores of the Assessment of Children's Hand Skills. Findings: Intra-rater reliability at item levels was generally acceptable, and both raters exhibited moderate to high agreement between the first and second evaluations (intraclass correlation coefficients = 0.61–0.93) at activity scores and children's composite scores. However, the agreement between the two raters was unacceptable for most hand-skill items and activity scores. After rater effects were adjusted by Rasch analysis in children's composite scores, the inter-rater reliability was improved (intraclass correlation coefficient = 0.81). Conclusion: This study shows that the Assessment of Children's Hand Skills based on video recordings is reliable within the same raters. Further research is required to confirm its inter-rater reliability by involving more training and raters with varied clinical experience.

Published: February 2014

Introduction: The purpose of this study was to establish reliability of the Role Checklist Version 2: Quality of Performance (Role Checklist V2: QP) and verify the internal consistency between paper and electronic administration. This revised Role Checklist includes a Part 3, which prompts clients to rank the quality of their current performance in occupational roles, thus adding an ‘insider view’, to complete the picture of clients' occupational role participation. Method: One hundred participants completed the Role Checklist V2: QP by paper and electronic means in a test—retest design. Findings: Estimates of kappa, weighted kappa, and Cronbach's alpha were used to measure the reliability of the Role Checklist V2: QP. For Part 1, kappa values for individual roles ranged from 0.53 to 0.95. Cronbach's alpha values representing percent agreement for Parts 2 and 3 showed a significant level of agreement between paper and electronic administrations. Values for Part 2 and 3 showed almost perfect agreement of 0.88 to 1.0. Conclusion: Kappa and Cronbach's alpha values indicate the Role Checklist V2: QP is a reliable instrument and can be administered confidently via either electronic means or paper and pencil to gather information about clients' role incumbency, role value, and satisfaction with role performance.
Contagious Joy:
Authors: Antliff Mark 
Published: February 2014

ABSTRACT
In 1913 a cross section of the London- and Paris-based avant-garde signed a public petition protesting the Paris Municipal government's censorship of Jacob Epstein's Tomb of Oscar Wilde. Published as a broadside in mid-March 1913 by the journal Action d'art, the petition was forgotten until Epstein highlighted it in his 1940 autobiography. The Action d'art group's defense of Epstein's tomb was premised on a theory of anarchist-individualism espoused by the journal's founder, André Colomer, and his “art action.” The movement itself proved a success, which resulted in the forging of strong ties between anarchist writers, artists, and the avant-garde community.
Peirce and Photography: Art, Semiotics, and Science
Authors: Robins Alexander 
Published: February 2014

ABSTRACT
In this article, I focus on Charles Sanders Peirce's viability for contemporary art history and criticism. I argue that in order to make sense of Peirce's published remarks on photographs they should be read in light of specific nineteenth-century uses of photography in experimental science. I argue that Peirce's comments on photography are consistent with a realist theory of science. It is only when these remarks are contextualized within a broader scientific project that we may begin to mine Peirce for his art historical value.

Published: February 2014

Context.—All positive screening of newborns for cystic fibrosis using the dried blood spot 2-tiered immunoreactive trypsinogen/DNA method requires subsequent sweat chloride testing for confirmation. Obtaining an adequate volume of sweat to measure chloride is a challenge for many cystic fibrosis centers across the nation. The standard for patients older than 3 months is less than 5% quantity not sufficient (QNS) and for patients 3 months or younger is less than 10% QNS.Objective.—To set up a quality improvement (QI) program for sweat testing to improve QNS rates using the Wescor Macroduct (Wescor, Inc, Logan, Utah) method at Texas Children's Hospital's laboratory, Houston, Texas.Design.—Single-center study.Results.—Quantity not sufficient rates were evaluated for 4 months before and 8 months after implementation of the QI program for patients aged 3 months or younger and those older than 3 months. The QI program included changes in technician training, service, site of collection, mode of collection, weekly review, and forms to screen patients for medications that may alter sweat production. A marked improvement was observed in the rates of QNS, which declined considerably from 16.7% to 8.5% (≤3 months old) and from 9.3% to 2.2% (&gt;3 months old) after implementation of the QI initiative in both age categories.Conclusion.—This report demonstrates the effectiveness of the QI program in significantly improving QNS rates in sweat chloride testing in a pediatric hospital.

Desplazamientos. Una reflexión sobre la posibilidad de escuchar el horror
Authors: Acedo Alonso Noemí 
Published: February 2014

Resumen: Las relaciones que existen entre la poesía y la representación del fenómeno de la Shoah han sido ampliamente estudiadas por la filosofía y los estudios literarios, interesados en todo lo que concierne a la memoria y al recuerdo del horror. Sin embargo, creo que las razones que llevan a algunos sobrevivientes de la última dictadura militar argentina a afirmar que la poesía es el género más adecuado para aproximarse a la representación del horror están todavía insuficientemente exploradas. A partir de la crítica filosófica de la representación y del estudio contemporáneo sobre la significación de la escucha, ahondaré en el sentido de la afirmación sobre la poesía y el horror. Palabras clave: representación, horror, visión, poesía, testimonio, escucha. Abstract: The relations that exist between the poetry and the representation of the Shoah have been widely studied by the philosophy and the literary studies, which are interested in what concerns the memory and the recollection of the horror. Nevertheless, I believe that the reasons that lead some survivors of the last military Argentine dictatorship to affirming that the poetry is the best genre to come closer the representation of the horror are still insufficiently explored. From the philosophical critique of the representation and of the contemporary study on the significance of the listening, I will go deeply into the sense of the affirmation on the poetry and the horror. Key words: representation, horror, vision, poetry, testimony, listening.
De los cruces entre el cine y la literatura: Osvaldo Soriano y la desmitificación del Olimpo hollywoodense
Authors: Previtera Roberta 
Published: February 2014

Resumen: Este artículo se propone investigar la recuperación del discurso cinematográfico operada por el escritor argentino Osvaldo Soriano. El autor retoma personajes arquetípicos, esquemas narrativos y convenciones descriptivas de los principales géneros cinematográficos hollywoodenses y las adapta al contexto cultural argentino. En particular se analizará la relación que se establece entre la novela Cuarteles de invierno y el género western. Se trata de una rescritura paródica en la que Soriano, desmitificando los valores tradicionalmente asociados al género, transmite un punto de vista crítico sobre el presente histórico. Palabras Clave:Soriano, desmitificación, cine, western, reescritura. Abstract: The aim of the work is studying how Osvaldo Soriano introduces elements of cinematographic speech in his novels. He picks up Hollywood archetypical characters, narrative formulas and descriptive conventions and adapts them to the Argentinean cultural context. In particular we will analyze the relationship between the novel Cuarteles de invierno and the western. This novel is a parody where Soriano operate a demystification of the genre’s values in order to transmit a critical evaluation of the contemporary society. Key Words:Soriano, demystification, cinema, western, rewriting.

Image Enlargement Based on Proportional Salient Feature
Authors: Somawirata I Komang , Uchimura Keiichi , Koutaki Gou 
Published: February 2014

AbstractThis paper proposes an image enlargement method that produces proportional salient content of image magnification. To obtain the proportional salient image content: first, we enlarge the source image to the high size of the target image using uniform enlarging. Second, we slice the image into sections from top to bottom following the minimum energy and detect the salient feature of the image. Third, we enlarge the slice of the image region that does not containthe salient feature of the image to the full size of the target image. The proposed method has been tested in several images, such as akiyo, butterfly, cameraman, canoe, dolphin, and parrot. The experimental results show that the proposed method results in a proportional content for image enlargement in the different ratios compared with the comparison method.

Published: February 2014

AbstractThis study assesses the relative effectiveness of solo and pair programming instructional strategies on students’ academic achievement in the Visual-Basic.Net Computer Programming Language. Two research questions and three null hypotheses guided the study. The sample comprised 68 subjects distributed over the three treatment groups (27 solo programmers, 24 pair programmers, and 17 conventional programmers) from three hundred computer science students of the Federal College of Education (Technical), Akoka, Yaba, Lagos State, Nigeria. The Visual-Basic.Net Achievement Test (VAT) was used to collect data for both the pre- and post-tests. The VAT test was administered to all 68 subjects in the three groups, first as pre-test and after treatment as post-test. Mean and standard deviations were used to answer the two research questions while ANCOVA and multiple comparisons were used in testing the three null hypotheses. The results of the analyses indicate that: (i) the experimental groups performed better than the control group, (ii) the treatment appeared to be more effective among male students than their female counterparts, (iii) the main effects of treatment and gender as well as the interaction effects of treatment and gender were not statistically significant.
