To Study the Efficacy of Laser Peripheral Iridoplasty in the Treatment of Eyes With Primary Angle Closure and Plateau Iris Syndrome, Unresponsive to Laser Peripheral Iridotomy, Using Anterior-Segment OCT as a Tool
Authors: Ramakrishnan Rengappa , Mitra Arijit , Abdul Kader Mohideen , Das Sasmita 
Published: September 2015

Purpose:To use anterior-segment optical coherence tomography (AS-OCT) as a tool to monitor the outcome of iridoplasty in patients with primary angle closure (PAC) and plateau iris syndrome (PIS), who were unresponsive to a previous laser peripheral iridotomy.Materials and Methods:This was a prospective, observational case control study. Patients diagnosed with PAC and PIS who had undergone laser peripheral iridotomy earlier, but were unresponsive to the procedure, were subjected to an iridoplasty. The intraocular pressure (IOP) and anterior-chamber parameters were measured before and after the procedure, and complications were noted. The patients were followed up for 1 year, and results were analyzed.Results:Twenty-four eyes of 12 patients underwent the iridoplasty procedure. Sixteen eyes were diagnosed as cases of PAC and 8 eyes were diagnosed as cases of PIS. Main outcome measures were the IOP, peripheral anterior synechiae, AS-OCT angle parameters, and complications. After iridoplasty, there was a significant decrease in the IOP from 24.4±5.6 to 16.5±5.4 mm Hg (P<0.001) at the final follow-up. The mean number of antiglaucoma medications decreased from 1.6±0.9 to 0.7±1.1. The medians of the peripheral anterior synechiae extent reduced from 3.5 (quartile range, 1.5 to 6.0) to 2.0 (quartile range, 0.5 to 4.0) clock hours in the PAC group (P<0.001) and from 3.8 (quartile range, 2.0 to 6.5) to 2.5 (quartile range, 0.8 to 5.0) clock hours in the PIS group (P<0.001). Changes in AS-OCT parameters noted were as follows: the AOD500increased from 0.132±0.016 to 0.179±0.062 mm (P<0.001), TISA500from 0.085±0.012 to 0.104±0.051 mm2(P<0.001), and scleral spur angle from 19.5±2.4 to 26.8±4.5 degrees (P<0.001). No significant changes in the angle-to-angle distance and the crystalline lens rise were found.Conclusions:In eyes with synechial angle closure and PIS that do not show an improvement after an iridotomy, laser peripheral iridoplasty can be very effective. There were no significant complications after the iridoplasty procedure, implying that it is quite safe. This study also demonstrates that AS-OCT can serve as a useful tool to document the preprocedure angle parameters, to note the changes after the procedure, and for the long-term follow-up of these patients.

Authors: Meziani Lyes , Tahiri Joutei Hassani Rachid , El Sanharawi Mohamed , Brasnu Emmanuelle , Liang Hong , Hamard Pascale , Baudouin Christophe , Labbe Antoine 
Published: September 2015

Purpose:
To compare characteristics of functioning blebs (FBs) and nonfunctioning blebs (NFBs) with en-face spectral-domain optical coherence tomography (OCT).

Methods:
We evaluated 41 blebs of 38 patients after a first-time trabeculectomy. Eyes were classified into 2 groups: FBs (22 eyes) and NFBs (19 eyes). En-face OCT images were analyzed semiquantitatively for the density of intraepithelial microcysts (0 to 3), internal fluid-filled cavity (0 to 3), and bleb vascularization (0 to 2). Presence of conjunctival fibrosis and visualization of the scleral flap were also analyzed.

Results:
FBs showed significantly more intraepithelial microcysts than did NFBs: the mean grading of microcyst density was 1.86 for FBs and 0.11 for NFBs (P<0.0001). None of the FBs were rated 0 and none of the NFBs were rated 2 or 3 for the density of intraepithelial microcysts. NFBs presented more conjunctival fibrosis than FBs (63% vs. 32%, P<0.05). There was no significant difference between FBs and NFBs for bleb vascularization, visualization of the scleral flap, and presence of subepithelial fluid-filled cavities. There was a direct correlation between postoperative intraocular pressure and intraepithelial microcyst density (r=−0.7655, P<0.0001). The long-term administration of preserved eyedrops before surgery was associated with fewer intraepithelial microcysts (r=−0.5436; P=0.0006).

Conclusions:
FBs were associated with a higher number of intraepithelial microcysts evaluated with en-face OCT. A higher density of microcysts was associated with a lower intraocular pressure and a shorter duration of preserved topical treatment before surgery. En-face OCT provides a simple, noninvasive, and reproducible method to analyze blebs after filtering surgery.
Theoretical triangulation and pluralism in accounting research: a critical realist critique
Authors: Modell Sven 
Published: September 2015

Purpose
– This is a rejoinder to Hoque et al. (2013) previously published in this journal. The purpose of this paper is to further elucidate and extend some of their key arguments related to the use of theoretical triangulation in accounting research.

Design/methodology/approach
– This is a conceptual discussion focusing on how the understanding of the notion of theoretical triangulation can be enhanced from a critical realist perspective.

Findings
– The author draws attention to some ambiguities in Hoque et al.’s (2013) reasoning and advance a critique of their rather under-developed conceptions of the relationship between ontology and epistemology, the epistemic premises influencing the choice of theories and the role of theories in conditioning empirical observations and scholarly knowledge claims. To address these issues the author advances a critical realist approach and discusses its implications for theoretical triangulation in accounting research.

Originality/value
– The paper contributes to the ongoing debate about theoretical pluralism in accounting research by explicating how critical realism may further such pluralism and the inter-disciplinary accounting research project more generally.
Antecedents and consequences of extrinsic superstitious beliefs: a cross-cultural investigation
Authors: Sierra Jeremy J. , Hyman Michael R. , Lee Byung-Kwan , Suh Taewon 
Published: September 2015

Purpose– The purpose of this paper is to advance the understanding of antecedents and consequences of superstitious beliefs.Design/methodology/approach– From survey data drawn from 206 South Korean and 218 US respondents, structural equation modeling is used to test the posited hypotheses.Findings– To extrinsic superstitious beliefs, both the South Korean and US models support the subjective happiness through self-esteem path and the anthropomorphism path; from these beliefs, both models support the horoscope importance path and the behavioral superstitious beliefs path. Only the US model supports the path from self-esteem to extrinsic superstitious beliefs, and only the South Korean model supports the path from intrinsic religiosity to extrinsic superstitious beliefs.Research limitations/implications– South Korean and US student data may limit generalizability. As effect sizes in this context are established, researchers have a benchmark for future quantitative superstition research.Practical implications– By further understanding antecedents and consequences of superstitious beliefs, marketers are in a better position to appeal to targeted customers. Anthropomorphism and intrinsic religiosity, not fully studied by marketing scholars, show promise as segmentation variables related to consumers’ attitudes and behaviors.Social implications– To avoid unethical practice, marketers must limit themselves to innocuous superstition cues.Originality/value– Leaning on experiential consumption theory and the “magical thinking” literature, this study augments the superstition literature by exploring carefully selected yet under-researched determinants and consequences of superstitious beliefs across eastern and western consumer groups.
From knowledge to knowing, from boundaries toboundary construction
Authors: Paraponaris Claude , Sigal Martine 
Published: September 2015

Purpose– Knowledge management is shot through with complex questions. This is certainly the case with regard to boundaries, as they constitute both a bounding line that has to be crossed if the knowledge required for innovation is to be diffused and a form of protection for scientific and technological organisations and institutions. This examination of boundaries leads to a state-of-the-art review that begins with the question of knowledge transfer. The authors start with foundations of the knowledge dynamic within organisations. Nevertheless, certain gaps were identified in the theory, as it did not seem so easy to carry out transfers. This led in turn to attempts to identify the boundaries that were causing difficulties and that had to be crossed. This led to an examination of the role of boundaries. What status could boundaries have when knowledge was expanding enormously within communities? Finally, the authors come face-to-face with knowledge management systems that have tended to redefine the forms that boundaries take.Design/methodology/approach– The paper uses a conceptual approach and is a meta analysis of the state-of-the-art review conducted to introduce the Special Issue “Knowledge Across Boundaries” JKM Volume 19, No. 5, 2015 (October).Findings– The notions of transfer and boundary demonstrated their usefulness in the development of a new theory, namely the knowledge-based view. These concepts were then critiqued, with reference, first, to the contexts in which communication takes place and, second, to the cognitive dimensions of the activity. Finally, studies showed that the cognitive and organisational approaches can be linked and that they shed light on many knowledge-sharing situations. Boundaries are no longer the object of attention, the focus having switched to the collective process of creating new concepts.Research limitations/implications– This state-of-the-art review is limited to the papers about Management Science.Practical implications– Knowledge hybridization is possible but must be referred to resources made available by the division of labour between disciplines (Shinn, 1997). Expansive learning (Engeström, 2010) is close to boundary construction (Holford, 2015) to indicate the dialectical view between instituting and instituted society (Castoriadis, 1975, 1987). We are now perhaps at the point of transition between the interest in “boundary spanners” and a new concern with “boundary construction”.Social implications– This paper introduces a methodology of knowledge transfer knowledge transfer in firms strategies of learning.Originality/value– The paper provides the concept (with examples) of ‘boundary construction’.
Sourcing knowledge for innovation: knowledge reuse and creation in project teams
Authors: Khedhaouria Anis , Jamal Arshad 
Published: September 2015

Purpose– The purpose of this paper is to investigate motivations of team members to source knowledge and how the sourced knowledge increases their reuse and creation outcomes.Design/methodology/approach– A model based on knowledge sourcing perspective is proposed and tested to link knowledge sourcing methods in teams to their performance outcomes. The hypotheses are tested on data collected from a survey of 341 project teams.Findings– The findings show the critical role of team members’ learning orientation in increasing knowledge sourcing, reuse and creation; group knowledge sourcing and repositories are more appropriate to increase knowledge reuse; the Internet is more effective to increase knowledge creation; and knowledge reuse increases knowledge creation among team members with a strong learning orientation.Research limitations/implications– Further studies can replicate the model presented in this paper and introduce group characteristics to improve its explanatory power. Also, use of self-reported measures in data collection may lead to biases; future research should collate different measures longitudinally or use separate primary and secondary observations.Practical implications– Team leaders should enhance team effectiveness by ensuring diversity of knowledge and skills. Current research emphasizes that team leaders can integrate a crowdsourcing or “users as co-creators” approach to increase knowledge creation by team members. Team members’ learning orientation can be increased by promoting a climate that encourages open discussion of problems, mistakes and errors.Originality/value– This research highlights that knowledge sourcing methods produce different performance outcomes regarding knowledge reuse and creation. These insights can be useful to team leaders and researchers to better understand what motivates team members to source knowledge and how it increases their reuse and creation outcomes.
The role of organizational and social capital in the firm’s absorptive capacity
Authors: Aribi Amal , Dupouët Olivier 
Published: September 2015

Purpose– This paper aims to ask the question of the contingency of a firm’s absorptive capacity upon the type of expected outcome. Thus, this paper looks at different expected outputs in terms of more or less radical innovations and sees if there are consequences on the absorptive process underpinning cognitive structures and processes, as embodied in its organizational and social capital.Design/methodology/approach– To do so, a qualitative study was conducted. In total, 23 persons in three French industrial firms were interviewed about their firm’s absorptive capacity. One of these firms aims at “new-to-the-firm” innovations, while the other two aim at “new-to-the-world” innovations.Findings– Results suggest that while “new-to-the-firm” innovations tend to favor the use of social capital, “new-to-the-world” innovations tend to rely more on organizational capital. These rather counterintuitive results are interpreted by the necessity to take into account other variables than knowledge distance in the absorption of new knowledge. In particular, complexity and time-length would call for greater use of organizational capital, while speed and reactivity would instead require greater use of social capital.Originality/value– This is to the best of the authors’ knowledge that one of the first study evidencing the contingent nature of the absorptive process. Further, results tend to show the form absorptive capacity takes depends not only on cognitive aspects but also on the particular environment the firm evolves in.
Development and operation of a fiber Bragg grating based online monitoring strategy for slope deformation
Authors: Guo Yongxing , Zhang Dongsheng , Fu Jianjun , Liu Shaobo , Zhang Shengzhuo , Zhu Fangdong 
Published: September 2015

Purpose
– The purpose of this paper is to investigate an online monitoring strategy that incorporates fiber Bragg gratings (FBGs) for deformation displacement detection, with the background that slope deformation monitoring is crucial to engineering safety supervision and disaster prevention.

Design/methodology/approach
– A “beam element” method has been proposed, introduced and experimentally verified in detail. The deformation displacement along a flexible bar can be obtained based on this method, using the distributed strain detected by the FBGs embedded in the bar. A novel sensor structure containing inclinometer casings and a series of connected flexible pipes with FBGs embedded has been proposed. Based on the features of this structure, two FBG deformation sensors have been manufactured and installed into a slope. A matched monitoring station which permits real-time supervision, warning and remote access across the Internet was established and operated.

Findings
– Displacement data from September 2013 to August 2014 are obtained, which is basically consistent with the practical situation.

Originality/value
– The FBG deformation sensors demonstrated a robust and reliable measurement performance, which is promising for real-time disaster warning in slope engineering.
Smooth estimation of human foot motion for zero-velocity-update-aided inertial pedestrian navigation system
Authors: Zhao Hongyu , Wang Zhelong , Gao Qin , Hassan Mohammad Mehedi , Alelaiwi Abdulhameed 
Published: September 2015

Purpose
– The purpose of this paper is to develop an online smoothing zero-velocity-update (ZUPT) method that helps achieve smooth estimation of human foot motion for the ZUPT-aided inertial pedestrian navigation system.

Design/methodology/approach
– The smoothing ZUPT is based on a Rauch–Tung–Striebel (RTS) smoother, using a six-state Kalman filter (KF) as the forward filter. The KF acts as an indirect filter, which allows the sensor measurement error and position error to be excluded from the error state vector, so as to reduce the modeling error and computational cost. A threshold-based strategy is exploited to verify the detected ZUPT periods, with the threshold parameter determined by a clustering algorithm. A quantitative index is proposed to give a smoothness estimate of the position data.

Findings
– Experimental results show that the proposed method can improve the smoothness, robustness, efficiency and accuracy of pedestrian navigation.

Research limitations/implications
– Because of the chosen smoothing algorithm, a delay no longer than one gait cycle is introduced. Therefore, the proposed method is suitable for applications with soft real-time constraints.

Practical implications
– The paper includes implications for the smooth estimation of most types of pedal locomotion that are achieved by legged motion, by using a sole foot-mounted commercial-grade inertial sensor.

Originality/value
– This paper helps realize smooth transitions between swing and stance phases, helps enable continuous correction of navigation errors during the whole gait cycle, helps achieve robust detection of gait phases and, more importantly, requires lower computational cost.

Authors: Zhan Yage , Yu Qiao , Wang Kun , Yang Fu , Zhang Borui 
Published: September 2015

Purpose
– The purpose of this paper is to theoretically analyze and experimentally demonstrate the investigation on and optimization of a distributed optical fiber sensor based on phase-sensitive optical time domain reflectometer (F-OTDR) for disturbance detection.

Design/methodology/approach
– The F-OTDR system is investigated and optimized in two aspects: the hardware parameter and the interrogation scheme.

Findings
– Based on the optimized hardware and the new interrogation scheme, the performances of the F-OTDR system have been improved greatly, compared with conventional F-OTDR system. A location accuracy of 2 m and a signal-to-noise ratio (SNR) of 16 dB have been achieved under a spatial resolution of 8 m. On the other hand, four disturbances at four different locations have been detected and located simultaneously, which is the most effective detection system with the maximum detection capability reported to date, to the best of the authors’ knowledge.

Originality/value
– Four disturbances at four different locations have been detected and located simultaneously, which is the most effective detection system with the maximum detection capability reported to date, to the best of the authors’ knowledge. With same hardware conditions, more existing disturbances can be detected by using the new interrogation scheme, which is helpful to reduce the miss report of disturbance.
Firm adoption of international standards: evidence from the Ethiopian floriculture sector
Authors: Gebreeyesus Mulu 
Published: September 2015

AbstractGlobal trade in agriculture and food products is increasingly governed by an array of standards. In order to continue exporting, developing countries have little choice but to comply with the new requirements. This study uses a census based panel data set from the nascent floriculture industry in Ethiopia to empirically examine the determinants of firms’ adoption of international private standards in fresh horticulture produce in large‐scale estate farms. The econometric analysis shows that larger size, older, and foreign owned firms are more likely to adopt the private standards. Moreover, this study analyzes the overall industry level efforts and public–private partnership to launch and implement a national scheme GAP and build a firm's capacity to comply with the standards.
New insights into the vertebral Hox code of archosaurs
Authors: Böhmer Christine , Rauhut Oliver W. M. , Wörheide Gert 
Published: September 2015

SUMMARYVariation in axial formulae (i.e., number and identity of vertebrae) is an important feature in the evolution of vertebrates. Vertebrae at different axial positions exhibit a region‐specific morphology. Key determinants for the establishment of particular vertebral shapes are the highly conserved Hox genes. Here, we analyzed Hox gene expression in the presacral vertebral column in the Nile crocodile in order to complement and extend a previous examination in the alligator and thus establish a Hox code for the axial skeleton of crocodilians in general. The newly determined expression of HoxA‐4, C‐5, B‐7, and B‐8 all revealed a crocodilian‐specific pattern. HoxA‐4 and HoxC‐5 characterize cervical morphologies and the latter furthermore is associated with the position of the forelimb relative to the axial skeleton. HoxB‐7 and HoxB‐8 map exclusively to the dorsal vertebral region. The resulting expression patterns of these two Hox genes is the first description of their exact expression in the archosaurian embryo. Our comparative analyses of the Hox code in several amniote taxa provide new evidence that evolutionary differences in the axial skeleton correspond to changes in Hox gene expression domains. We detect two general processes: (i) expansion of a Hox gene's expression domain as well as (ii) a shift of gene expression. We infer that the ancestral archosaur Hox code may have resembled that of the crocodile. In association with the evolution of morphological traits, it may have been modified to patterns that can be observed in birds.
Time‐dependent localization of high‐ and low‐sulfated keratan sulfates in the song nuclei of developing zebra finches

Published: September 2015

AbstractKeratan sulfate proteoglycans (KSPGs) and chondroitin sulfate proteoglycans (CSPGs) consist of a protein core with covalently attached glycosaminoglycan side chain. Although CSPGs are known to regulate the end of the critical period, the role of KSPGs in brain development remains unclear. Young male zebra finches memorise song templates during development. The brain regions that are responsible for song learning, known as song nuclei, are recognized as a suitable model for the study of brain development. To understand the potential role of KSPGs, here we examined the localization of KSs with different degrees of sulfation in the brain of developing male zebra finches. Exclusively in the song nuclei, an increase in expression of 5‐D‐4‐positive (5‐D‐4+) high‐sulfated KS started after hatching, and reached a plateau at the end of the sensory period, during which the young bird listens to and memorises the song of an adult tutor. By contrast, weak and ubiquitous expression of BCD‐4+ low‐sulfated KS remained unchanged until the end of the sensory period, and first increased in the song nuclei at the end of the sensorimotor period, during which the young bird produces plastic songs. Immunoblot analysis showed that phosphacan was a common core protein of 5‐D‐4+ KS and BCD‐4+ KS. Finally, we confirmed that the sulfotransferase responsible for the synthesis of high‐sulfated KS was exclusively localised in the song nuclei. Our observations suggest that time‐dependent localization of KSPGs with different sulfation patterns in the song nuclei may underlie song learning in developing male zebra finches.
