Authors: Jbarah Rema , Geal-Dor Miriam , Rich Shanit , Adler Miriam , Yehezkely Michal Kaufmann 
Published: August 2013

Abstract

Background: Implantation at a young age enables exposure to language and speech during the critical age for language acquisition. Long duration of auditory deprivation may lead to less optimal results.

Methods: A retrospective review of cases was performed. A young girl with congenital bilateral profound sensorineural hearing loss received her first cochlear implant on the right side at the age of 2½ years and successfully developed good speech and language. At the age of 10 years, explantation had to be performed, and as reimplantation could not be done on the same side, the implantation was done on the left ear, which had never received auditory stimulation. Two age-matched girls with bilateral sequential implantation, in whom the second sound-deprived ear was implanted after a long duration, were studied as well.

Results: A year after implantation, in two of the cases there was very good speech perception, even in noise. In one case, the second ear never attained the ability to understand speech.

Conclusions: These results can be explained in light of recent findings that early unilateral stimulation can result in bilateral representation in the auditory cortex.
Engaging Black Males on Their Own Terms: What Schools Can Learn from Black Males Who Produce Hip-Hop
Authors: Irby Decoteau J. , Petchauer Emery , Kirkland David 
Published: August 2013

AbstractEducation scholars and practitioners have much to learn about engagement and motivation of Black males by directing their inquiries to more organic sites of hip-hop cultural production outside of schools. One such site is the hip-hop’s informal labor economy where Black males engage in earning money through hip-hop cultural production. Labor practices include a myriad of activities such as beat making, promoting shows, teaching dance classes, managing studios and recording sessions, artist development, visual art, and other modes of hip-hop cultural production. Through exploring the decision-making process of Black males that opt to participate in informal labor in lieu of formal labor, we examine what it is that compels their engagement and motivation efforts in hip-hop production. We find that participating in hip-hop cultural production gives Black males: (1) the autonomy to control their own image and maintain their individuality and (2) a sense of worth and belonging to something positive. From these findings, we discuss the need for schools to model themselves after such fields where Black males demonstrate high levels of engagement, motivation, and mastery.
Applying systemic functional linguistics in healthcare contexts
Authors: Matthiessen Christian M. I. M. 
Published: August 2013

AbstractThis paper is concerned with research on healthcare communication that draws on Halliday's systemic functional linguistics (SFL). Section 1 introduces Halliday's notion of appliable linguistics, with SFL as a particular manifestation. Section 2 deals with instances of healthcare communication in the form of medical consultations, and shows how they can be illuminated through SF text analysis. Section 3 relates medical consultations to institutions of healthcare along two dimensions, stratification and instantiation; and it suggests that institutions can be analyzed as aggregates of situation types. Section 4 considers the field of activity within healthcare contexts, suggesting how texts in situation types characterized by different fields complement one another. Section 5 adds tenor considerations in the form of the institutional healthcare roles across fields. Section 6 explores patient journeys through hospitals as sequences of situation types. Section 7 asks how risks and failures inherent in patient journeys can be interpreted, and then analyzed and addressed, in terms of the orders of systems in a hospital. Section 8 continues this systemic analysis, applying them to patients, and Section 9 extends the analysis to healthcare systems, as semo-technical systems. Section 10 shows how relationship-centered healthcare can be interpreted in terms of SFL.
Interlingual re-instantiation – a new systemic functional perspective on translation
Authors: Farias de Souza Ladjane Maria 
Published: August 2013

AbstractFrom a systemic functional perspective, translation has been dealt with mostly by means of the hierarchy of realization and has been modeled against parameters of difference between language systems – equivalence and shift. Such a concern with equivalence between language systems reflects the primary focus of research on the supporting language theory itself. As recent developments in systemic functional linguistics have shifted focus from system to uses and users, proposing three complementary hierarchies – realization, instantiation, and individuation – a more comprehensive perspective on translation has been enabled, which includes the systems, uses, and users involved. In tune with recent developments in translation studies, it views translation as a negotiation of meanings (including the notion of “equivalence”) between users via a specific use – the translated text. This article introduces this new model, its foundations, proposed concepts, and suggested methodology, as well as a glimpse of the model at work.
Systemic functional linguistics, corpus linguistics, and the ideology of science
Authors: Hunston Susan 
Published: August 2013

AbstractThis paper considers the relationship between research using systemic functional linguistics and research of the kind referred to as corpus linguistics, specifically in a study of ideology in a popular science text. The paper argues that ideas in SFL and corpus linguistics may be regarded as parallel (register), divergent (grammar and phraseology), and complementary (lexis and taxonomy). Following a review of research in these areas, the paper presents a case study of evaluation of status in a popular science book (
Hallidayan systemic-functional semiotics and the analysis of the moving audiovisual image
Authors: Bateman John A. 
Published: August 2013

AbstractAlthough linguistically inflected semiotic approaches to film were pursued in the 1960s and 1970s, they have since been almost universally rejected within film studies and film theory even though film is precisely the kind of intentionally produced communicative artifact for which one would have expected semiotics to have much to offer. Traditionally, forms of semiotics modeled on linguistics have offered some of the most finely articulated accounts available but, so far, this has not been shown convincingly for film. This paper argues that the semiotics of the 1960s and 1970s was just too undeveloped to deal with entities as complex as film. In contrast, the multidimensional account of verbal semiotic systems articulated within Hallidayan systemic-functional semiotics over the past forty years is now dissolving many of the original problems and provides renewed impetus for the semiotic analysis of film, reinstating much expanded notions of
Multimodal digital semiotics: the interaction of language with other resources
Authors: O'Halloran Kay L. , E Marissa K. L. , Podlasov Alexey , Tan Sabine 
Published: August 2013

AbstractA “multimodal digital semiotics” approach, involving the development and use of interactive digital media technology, mathematical techniques of analysis and scientific visualization for modeling and analyzing multimodal phenomena, is demonstrated through the analysis of an interview between a climate scientist and a climate denialist on Fox News. Prototype software for multimodal analysis and network visualizations are used in combination with Allen's interval algebra to model multimodal semantic data and identify significant patterns based on temporal relationships between different semiotic choices. The resulting semantic patterns reveal combinations of semiotic choices that were drawn upon by the different speakers during the interview, accounting for how the climate denialist emerges as the dominant and convincing interviewee. Such an approach combines the objectivity of mathematical modeling and scientific visualization with the interpretive power of Halliday's systemic theory.
A Study on a Novel PCP’s Structure Using Finite Element Analysis

Published: August 2013

Abstract
In a progressive cavity pump (PCP), the rubber stator is not only susceptible to damage, and thus is a major factor affecting the pump’s performance. To date, however, an experimental method to test the deformation and forced state of the elastomer of a stator under real operating conditions is still not available. In order to study the deformation of PCP’s elastomer, a numerical simulation method, finite element analysis (FEA), has been successfully applied. In order to improve PCP’s working efficiency and life, a novel structure, in which the elastomer is covered over the rotor rather than over the stator, is put forward, and the general structure performance is analyzed by FEA. Hereinafter PCP with this novel structure is called "construction A".
Another idea to improve the failure resistance of PCP’s elastomer is to use some kind of reinforced material inside the rubber sleeve. Similar reinforced structures have been widely applied in other products, for instance, car tires. In a tire, there are various cords which are used as reinforcement layers. Steel cords, nylon cords, polyester cords, rayon cords and some hybrid cords are mature reinforcement materials in the tire industry. In this study, nylon cords are adopted to reinforce the structure of "construction A", which is hereinafter called "construction B". A comparison of structure performance between "construction A" and "construction B" has been conducted based on FEA results. It should be noted that even though stress and strain in both constructions are the same, "construction B" will have longer lifetimes than "construction A" because of greater failure resistance exhibited by "construction B".
The purpose of this research is to find the difference between the two proposed novel constructions and the conventional construction. Based on the FEA analysis, the practicability of the novel PCPs can be assessed.
A Computational Model for Analysis of Fluid-Structure Interaction within Elastomeric Progressing Cavity Pumps

Abstract
Progressing Cavity Pumps (PCP) are positive-displacement pumps customarily employed in the petroleum industry for artificial lift of high viscosity oils, or fluids with moderate degree of gas and/or sediments. Basically, an elastomeric PCP consists of a metallic helical rotor and a twin helix rubber stator. For this kind of PCP, flow is strongly modified by structural deformations undergone by the stator. For automation, design and operation optimization purposes, any mathematical model able to accurately describe and predict flow and structural phenomena inside these pumps is welcome. However, due to its intrinsically coupled non-linear multiphysics - flow and structural fields, friction, wear, heat generation - analysis of the real dynamic interaction is very complex and experimental measuring is extremely hampered by the elastomeric nature of the stator. Therefore, as an attempt to describe and numerically evaluate this dynamic behavior, the present work features a simplified three-dimensinoal computational model for analysis of the fluid-structure interaction (FSI) in single-lobe elastomeric progressing cavity pumps. The governing unsteady and three-dimensional fluid dynamic equations, for laminar or turbulent flow, are solved using an Element-based Finite Volume Method in a moving and deformable mesh, to account for the relative motion between rotor and stator, and the stator deformation as well. Once a pressure distribution on the stator inner surface is obtained, for an initial non-deformable fluid domain/geometry, it is then used to evaluate the corresponding structural deformations of the elastomeric stator. In the present model, only radial deformations are allowed, being explicitly evaluated following an elastic linear model. This procedure is continuously repeated until "converged" geometrical configuration and flow field are reached before a new time step is advanced. In addition to dynamically provide detailed information on flow and structural fields (pressure, velocity, deformation and tension distributions), operational parameters such as volumetric efficiency, viscous loses and torque, for example, are precisely predicted by the model developed as function of several parameters (rotor and stator dimensions, pump rotation and differential pressure, fluid viscosity, and elastomer bulk modulus). Numerical results are presented and compared against experimental findings, illustrating the behavior of the main fields, for the different governing parameters.
Relationships Among Vegetation Indices Derived from Aerial Photographs and Soybean Growth and Yield

Published: August 2013

ABSTRACTImproving crop productivity in drought‐prone environments is a daunting challenge. Selection of advanced breeding materials for yield is a labor‐intensive procedure and sometimes produces misleading results because of the complex genetic behavior of yield. Remote sensing techniques can provide an instantaneous, nondestructive, and quantitative assessment of a crop's ability to intercept radiation and photosynthesize. The objective of this study was to examine vegetation indices derived from aerial images as biomass and yield prediction tools for soybean [Glycine max (L.) Merr.] under different levels of water availability. Two commercial soybean cultivars with contrasting maturity were planted on a rooting‐depth restriction installation. Multispectral aerial images were acquired at early flowering and during seed filling, and fifteen vegetation indices were calculated and their associations with yield and biomass assessed. The indices estimated using the near infrared (NIR), RED, and GREEN portions of the spectrum were weak predictors of soybean yield under severe water stress conditions. However, under moderate drought or unstressed conditions, the regressions were able to explain up to 80% of the data on the basis of R2 values. The nominally best relationships with yield were found for NIR from images taken at seed fill and with biomass for RED bands extracted from images taken at flowering. Results suggest that aerial imaging shows potential as a tool for yield and biomass prediction of soybean cultivars.

ABSTRACTGenetic information on sainfoin (Onobrychis viciifolia Scop.), an important forage species, is highly limited. In this study, genetic diversity and trait relationships of 80 sainfoin accessions were evaluated using morphological, anatomical, and inter‐simple sequence repeats (ISSR) characteristics. Results of 2 yr of study indicated a wide range of variability in the germplasm using all three data sets. Based on morphological assessment, accessions were divided into three different groups that could be easily identified by traits such as palatability, resistance to powdery mildew, and percentage of plant shoot and leaf. On the other hand, great diversity was found for anatomical traits, especially vessel diameter, sieve diameter, width of phloem, and xylem/phloem ratio, possibly indicating different mechanisms of water and solute transport among populations. Results indicated that anatomical traits were less influenced by environmental constraints compared with agro‐morphological traits. Accessions with high vessel diameter and large xylem diameter were may be palatable. Result of ISSR markers showed that high genetic variation among accessions can be closely related to “Isolation by distance” model, resulting in accessions falling into two main clusters (Iranian and the exotics), each having four subclusters. Most of the genetic variance was found among the accessions and less among the geographical groups. Results suggested that Asia and Eastern Europe may be the main center of diversity for this species.

ABSTRACTA previously identified genic male sterile (GMS) line in Brassica napus L. (rapeseed), in which the male sterile trait is controlled by a monogenic dominant locus, has been designated as MDGMS. In this study, we cloned importin‐α‐like sequences in MDGMS and its allelic fertile line. When we compared complementary DNA (cDNA) and deduced amino acid sequences of both cloned regions, several mutations were detected between the two lines. Sequence analysis revealed that the cloned gene contains 10 exons and 9 introns, consistent with IMPa‐4 in Arabidopsis spp., and it was accordingly designated as BnIMPα (Brassica napus importin α). Splice junctions of all introns in BnIMPα follow the GT–AG rule, and the amino acid sequence of BnIMPα contains the nuclear localization signal (NLS) sequence RKKIYKTGVDADEARRRR. The BnIMPα protein possesses characteristic features of importin α, such as an importin β binding (IBB) domain, eight tandem armadillo (ARM) repeats, and two helix–turn–helix motifs (HEAT) repeats. BnIMPα ribonucleic acid interference (RNAi) resulted in sterility or reduced fertility of male and female gametes, indicating that BnIMPα is necessary for gametogenesis in B. napus. Compared with the wild‐type, RNAi plants were highly susceptible to downy mildew and viral diseases. Tissue and subcellular localization analysis indicated that BnIMPα is expressed in all plant tissues other than seeds, especially conducting tissue and stamens, and that BnIMPα is localized in the nucleus.
Accounting Education Research: Ranking Institutions and Individual Scholars

Published: August 2013

ABSTRACT
Previous rankings of accounting literature have largely ignored the subtopic of accounting education research. Given the important role that rankings play in creating incentives and benchmarks, ranking education research may improve both the quality and quantity of research in this subtopic. This paper ranks academic institutions and individual accounting researchers based on their production of accounting education research. We show that the correlation between education research rankings and singular, noneducation research rankings is very low (i.e., ranges from 0.20 to 0.31), emphasizing the importance of considering education rankings separately from other topical areas in accounting research. We also provide evidence of the institutional factors that contribute to producing accounting education research and when professors produce this type of research in their careers. These findings will likely be of interest to current faculty, administrators, and industry leaders as they make decisions based on accounting education research.

Published: August 2013

Abstract
Objective—To characterize biomechanical differences in gait between dogs with and without an amputated thoracic limb.
Animals—Client-owned dogs (16 thoracic-limb amputee and 24 quadruped [control] dogs).
Procedures—Dogs were trotted across 3 in-series force platforms. Spatial kinematic and kinetic data were recorded for each limb during the stance phase.
Results—Amputees had significant increases in stance duration and vertical impulse in all limbs, compared with values for control dogs. Weight distribution was significantly increased by 14% on the remaining thoracic limb and by a combined 17% on pelvic limbs in amputees. Braking ground reaction force (GRF) was significantly increased in the remaining thoracic limb and pelvic limb ipsilateral to the amputated limb. The ipsilateral pelvic limb had a significantly increased propulsive GRF. The carpus and ipsilateral hip and stifle joints had significantly greater flexion during the stance phase. The cervicothoracic vertebral region had a significantly increased overall range of motion (ROM) in both the sagittal and horizontal planes. The thoracolumbar vertebral region ROM increased significantly in the sagittal plane but decreased in the horizontal plane. The lumbosacral vertebral region had significantly greater flexion without a change in ROM.
Conclusions and Clinical Relevance—Compared with results for quadruped dogs, the vertebral column, carpus, and ipsilateral hip and stifle joints had significant biomechanical changes after amputation of a thoracic limb. The ipsilateral pelvic limb assumed dual thoracic and pelvic limb roles because the gait of a thoracic limb amputee during trotting appeared to be a mixture of various gait patterns.

Abstract
Objective—To evaluate biomechanical gait adaptations in dogs after amputation of a pelvic limb.
Animals—Client-owned dogs (12 pelvic limb–amputee and 24 quadruped [control] dogs).
Procedures—Dogs were trotted across 3 in-series force platforms. Spatial kinematic and kinetic data were recorded for each limb during the stance phase.
Results—Pelvic limb amputees had increased peak braking forces in the contralateral thoracic limb and increased propulsive forces and impulses in both the ipsilateral thoracic limb and remaining pelvic limb. Time to peak braking force was significantly decreased, and time to peak propulsive force was significantly increased in all remaining limbs in amputees. Amputees had an increase in range of motion at the tarsal joint of the remaining pelvic limb, compared with results for the control dogs. Amputees had increased vertebral range of motion at T1 and T13 and increased vertebral extension at L7 within the sagittal plane. In the horizontal plane, amputees had increased lateral bending toward the remaining pelvic limb, which resulted in a laterally deviated gait pattern.
Conclusions and Clinical Relevance—Pelvic limb amputees adjusted to loss of a limb through increased range of motion at the tarsal joint, increased range of motion in the cervicothoracic and thoracolumbar vertebral regions, and extension of the lumbosacral vertebral region, compared with results for the control dogs. Amputees alternated between a laterally deviated gait when the pelvic limb was in propulsion and a regular cranially oriented gait pattern when either forelimb was in propulsion with horizontal rotation around L7.
