Influence of skill and exercise training parameters on locomotor recovery during stroke rehabilitation
Authors: Hornby T. George , Moore Jennifer L. , Lovell Linda , Roth Elliot J. 
Published: September 2016

Purpose of review
Research findings from the fields of motor learning and exercise physiology suggest specific training parameters that can be manipulated during physical rehabilitation profoundly influence skilled task performance. This review details the rationale for some of these training variables and their application in selected intervention studies focused on improving walking function in patients poststroke.

Recent findings
Basic and applied studies have shown that the amount, intensity, and variability of specific task practice applied during rehabilitation interventions can affect recovery of walking poststroke. Many studies detailing the effects of conventional, therapist, and mechanically assisted interventions may incorporate some of these training parameters but minimize others, and their relative contributions may influence walking outcomes. Specific patient factors, such as the stroke acuity and degree of impairments, appear to influence the relative contributions of these training variables, and different patient subgroups may benefit from greater emphasis on specific parameters.

Summary
The present findings suggest these training parameters should be considered when evaluating or implementing physical interventions directed toward improving locomotor function poststroke. More work is needed to understand their optimal combinations to maximize walking outcomes in patients with different levels of impairment poststroke.

Authors: Bouffard Marc A. , Cornblath Wayne T. , Rizzo Joseph F. , Lee Michael S. , DeLott Lindsey B. , Eggenberger Eric R. , Torun Nurhan 
Published: September 2016

Background:
Transient monocular vision loss (TMVL) is an alarming symptom owing to potentially serious etiologies such as thromboembolism or giant cell arteritis. Our objective is to describe the phenomenon of TMVL present on awakening, which may represent a distinct and benign entity.

Methods:
We performed a retrospective observational case series of 29 patients who experienced TMVL on awakening. Patients who described monocular dimming or blackout of vision were included, and those with blurred vision, concurrent eye pain, and binocular vision loss were excluded. Descriptive statistics were used to summarize the study population.

Results:
Of the 29 patients we studied, 90% (n = 26) were female and 48% had crowded discs (cup-to-disc ratio ≤0.2). The mean age was 45.4 years, although women were significantly younger than men (mean ages 43.4 and 62.7 years, respectively, P = 0.017). Brain magnetic resonance imaging and vascular imaging (magnetic resonance angiography, computed tomographic angiography, or carotid Doppler) were performed in 69% and 55% of cases, respectively, and were uniformly negative. In 14 patients for whom clear follow-up data could be obtained, no medically or visually significant sequelae of this syndrome were found, and 50% experienced resolution of symptoms.

Conclusions:
Evaluation was uniformly negative when patients described waking with isolated vision loss in 1 eye with subsequent resolution, usually in less than 15 minutes. The natural history seems benign with symptoms frequently remitting spontaneously. This visual phenomenon may represent an autoregulatory failure resulting in a supply/demand mismatch during low-light conditions.
Ocular and Cerebral Emboli From an Atrial Myxoma
Authors: Kuonen Anne , Borruat François-Xavier 
Published: September 2016

Abstract:
Emboli from an atrial myxoma resulted in asymptomatic segmental retinal and choroidal arterial hyperfluorescent lesions on retinal angiography, mimicking an arteritis. The retinal lesions disappeared after removal of the atrial myxoma. Endothelial trauma by embolic material appears to be the mechanism of the angiographic findings.
Personality and interest in the visual arts
Authors: Bachleda Catherine L. , Bennani Asmae 
Published: September 2016

Purpose
The purpose of this paper is to explore the relationship between personality and interest in the visual arts in a sample of Moroccan workers.

Design/methodology/approach
Data were gathered from 210 respondents to an online survey.

Findings
Results indicate that interest in the visual arts is associated with openness and sensation seeking, even after controlling for income and education.

Practical implications
This study suggests that to increase consumption of visual arts products or experiences, arts marketers should focus on the personality traits of openness and sensation seeking rather than the demographic variables of income and education.

Originality/value
Results extend conclusions about openness and interest in the visual arts to a non-student sample and extend the importance of sensation seeking to visual art interests as opposed to visual art preferences and art judgement. This study also represents the first empirical examination of interest in the arts in Morocco.
Making sense of organizational structure change: a practice-based approach
Authors: Rosenberg Age , Keller Margit 
Published: September 2016

PurposeThe purpose of this paper is to understand how employees make sense of a structural change in a public organisation, in order to understand which practices form this change and how individual elements (rules, understandings etc.) may shape the process of such changes.Design/methodology/approachThe research is based on: a two-wave interview method, where the same individuals from different levels of the organisation were questioned in both 2012 and 2014; and an analysis of the formal documents created during the decision-making process. Schatzki’s (1996) approach is used as the basis to identify teleo-affective structures, practical understandings and rules as constitutive elements of the practices that comprised the structural change in the organisation.FindingsThe analysis revealed two main practices – structural reorganisation and the sharing of information and involving employees – that shaped the process of structural change within the organisation. These practices are formed of positive and negative ways of doing, some of which have become in-house habits and a few which have become rules of the organisation. There were competing understandings and enactments of named elements in the organisation, indicating that organisational practices exist beyond individuals and that it takes a collective effort to change them.Research limitations/implicationsThe retrospective interview technique and use of employees’ subjective sense-making did not allow us to fully grasp how practices unfolded during the process of a change to the everyday workings of the organisation, which could only be accomplished by direct observations.Originality/valueThe research highlighted those processes that influence one of the potentially most important changes to any organisation, that of organisation structure – both extensive and compact – which has thus far seldom been studied. The authors empirically tested Schatzki’s (1996) approach to practices and provided a set of categories for analysing practices during such changes.
Simulation and detection of small crack-like surface flaws and slots in simply-supported beams using curvature analysis of analytical and numerical modal displacement data
Authors: Samami Hassan , Oyadiji S. Olutunde 
Published: September 2016

Purpose
The purpose of this paper is to employ analytical and numerical techniques to generate modal displacement data of damaged beams containing very small crack-like surface flaws or slots and to use the data in the development of damage detection methodology. The detection method involves the use of double differentiation of the modal data for identification of the flaw location and magnitude.

Design/methodology/approach
The modal displacements of damaged beams are simulated analytically using the Bernoulli-Euler theory and numerically using the finite element method. The principle used in the analytical approach is based on changes in the transverse displacement due to the localized reduction of the flexural rigidity of the beam. Curvature analysis is employed to identify and locate the structural flaws from the modal data. The curvature mode shapes are calculated using a central difference approximation. The effects of random noise on the detectability of the structural flaws are also computed.

Findings
The analytical approach is much more robust in simulating modal displacement data for beams with crack-like surface flaws or slots than the finite element analysis (FEA) approach especially for crack-like surface flaws or slots of very small depths. The structural flaws are detectable in the presence of random noise of up to 5 per cent.

Originality/value
Simulating the effects of small crack-like surface flaws is important because it is essential to develop techniques to detect cracks at an early stage of their development. The FEA approach can only simulate the effects of crack-like surface flaws or slots with depth ratio greater than 10 per cent. On the other hand, the analytical approach using the Bernoulli-Euler theory can simulate the effects of crack-like surface flaws or slots with depth ratio as small as 2 per cent.
Dynamic analysis of concrete gravity dam-reservoir systems by approximate wavenumber approach
Authors: Zare Estakhraji Seyed Iman , Lotfi Vahid 
Published: September 2016

Purpose
Recently, the original Wavenumber approach was introduced for dynamic analysis of dam-reservoir systems in frequency domain in the context of pure finite element programming. But its main disadvantages are that it cannot be implemented in time domain. The purpose of this paper is to propose an approximation to the original approach which enables one to carry out this effective method in time domain as well as in frequency domain. Based on the present investigation, it is proven that the Approximate Wavenumber approach has inherent characteristics, which allows it to be envisaged as an effective technique for calculating the response of concrete gravity dam-reservoir systems in time domain.

Design/methodology/approach
The method is described initially. Subsequently, the response of an idealized triangular dam-reservoir system is obtained by the proposed approach as well as by applying two other well-known absorbing conditions which are widely utilized in practice. The results are also controlled against the corresponding exact responses. It should be emphasized that all results presented herein are obtained by the FE-FE method under different absorbing conditions applied on the truncation boundary. These include two well-known absorbing conditions referred to as Sommerfeld and Sharan as well as the proposed approach of the present study (i.e. Approximate Wavenumber condition).

Findings
It is concluded that the maximum error for the Approximate Wavenumber approach is in the range of 10 percent at the major peaks of the response. This occurs mainly for the very low reservoir lengths under full reflective reservoir base condition and vertical excitation. This is a remarkable result for any kind of robust truncation boundary simulation that one may expect. The fundamental frequency of the system is captured correctly for the Approximate Wavenumber approach, even in cases of low reservoir length.

A non-locking composite tetrahedron element for the combined finite discrete element method
Authors: Lei Zhou , Rougier Esteban , Knight Earl E. , Frash Luke , Carey James William , Viswanathan Hari 
Published: September 2016

Purpose
In order to avoid the problem of volumetric locking often encountered when using constant strain tetrahedral finite elements, the purpose of this paper is to present a new composite tetrahedron element which is especially designed for the combined finite-discrete element method (FDEM).

Design/methodology/approach
A ten-noded composite tetrahedral (COMPTet) finite element, composed of eight four-noded low order tetrahedrons, has been implemented based on Munjiza’s multiplicative decomposition approach. This approach naturally decomposes deformation into translation, rotation, plastic stretches, elastic stretches, volumetric stretches, shear stretches, etc. The problem of volumetric locking is avoided via a selective integration approach that allows for different constitutive components to be evaluated at different integration points.

Findings
A number of validation cases considering different loading and boundary conditions and different materials for the proposed element are presented. A practical application of the use of the COMPTet finite element is presented by quantitative comparison of numerical model results against simple theoretical estimates and results from acrylic fracturing experiments. All of these examples clearly show the capability of the composite element in eliminating volumetric locking.

Originality/value
For this tetrahedral element, the combination of “composite” and “low order sub-element” properties are good choices for FDEM dynamic fracture propagation simulations: in order to eliminate the volumetric locking, only the information from the sub-elements of the composite element are needed which is especially convenient for cases where re-meshing is necessary, and the low order sub-elements will enable robust contact interaction algorithms, which maintains both relatively high computational efficiency and accuracy.
Performance outcomes and success factors of industrial vending solutions
Authors: Falasca Mauro , Kros John F. , Nadler S. Scott 
Published: September 2016

Purpose
Industrial vending solutions are unique in that they represent a very specific form of vendor-managed inventory (VMI). The purpose of this paper is to investigate performance outcomes associated with industrial vending implementation, a topic that has been largely ignored by the academic community.

Design/methodology/approach
A survey instrument was developed from earlier work on VMI success. Structural equation modeling is used to identify relationships between three enablers (information exchange, information quality, and relationship quality), perceived vending system implementation success, and three outcomes (cost benefits, customer service benefits, and inventory benefits).

Findings
Statistical outcomes demonstrate support for the benefits arising from successful vending system implementation. This study demonstrates that industrial vending implementation success is strongly tied to the amount and quality of the information shared between the relationship partners.

Practical implications
Successful industrial vending implementation results in improved inventory control, increased levels of customer service, and tighter cost control. This study provides supply chain managers with current findings, which should aid them in evaluating their current and proposed vending solutions.

Originality/value
Although VMI has been studied in the past, little work has been conducted on industrial vending as a specific form of VMI. This is the first study to explore industrial vending from the viewpoint of VMI implementation and performance. Empirically tested study results that are grounded in transaction cost theory confirm a series of performance outcomes of industrial vending from a buyer’s perspective as well as a number of enablers for successful industrial vending implementation.
Why be first if it doesn’t pay? The case of early adopters of C-TPAT supply chain security certification
Authors: Ni John Z. , Melnyk Steve A. , Ritchie William J. , Flynn Barbara F. 
Published: September 2016

PurposeThe purpose of this paper is to focus on adoption of certified management standards, specifically public standards. Such standards play an increasingly important role in today’s business environment. However, to generate adoption benefits, they must be first widely accepted – a situation where they have become viewed as the de facto norms. For this state to occur early adopters play a critical role. Past research has argued that early adopters, in exchange for assuming more risk, are rewarded with higher economic returns. Yet, these findings are based on private, not public standards. With public standards, early adopters do not receive such benefits. There is evidence that public standards are becoming more important. This situation leads to a simple but important question addressed in this study – if early adopters assume the risks of embracing a new public standard without economic benefits, then what is their motivation? To resolve this question, this study draws on agency theory and prospect theory. The authors argue that early adopters embrace such standards because of their desire to minimize risk resulting from failure to support the goal at the heart of the public standards.Design/methodology/approachData were obtained from the Customs-Trade Partnership Against Terrorism (C-TPAT) Partners Cost Benefit Survey and analyzed through structural equation modeling.FindingsEarly adopters of public standards are not driven by economic benefits but rather by the need to minimize their exposure to the risks associated with failing to satisfy the goals associated with a public standard. In other words, they were motivated by the need to minimize costs. In the case of C-TPAT, these costs are those of failing to provide or improve network security.Research limitations/implicationsThis study has shed new light on the standards adoption process by clarifying the specific motivations that drive early adoption of a public standard. In addition to identifying the loss aversion motives of early adopters and economic benefit motives of later adopters, the authors have also elaborated on the notion that standards have differing levels of precedence, particularly when comparing private with public standards.Practical implicationsIn a world characterized by increasing demands for outcomes such as improved security and where governmental funding is falling, due to growing deficits and governments that are becoming more conservative, the authors expect the use of public standards to increase.Originality/valueDifferent from prior research on private standard, the paper focuses on the organizations involved in the adoption and diffusion of a public standard, with special attention being devoted to the early adopters. The paper provides a theoretical explanation for the actions of early adopters of a public standard through the theoretical lens of prospect theory.
Capturing value from big data – a taxonomy of data-driven business models used by start-up firms
Authors: Hartmann Philipp Max , Zaki Mohamed , Feldmann Niels , Neely Andy 
Published: September 2016

Purpose
The purpose of this paper is to derive a taxonomy of business models used by start-up firms that rely on data as a key resource for business, namely data-driven business models (DDBMs). By providing a framework to systematically analyse DDBMs, the study provides an introduction to DDBM as a field of study.

Design/methodology/approach
To develop the taxonomy of DDBMs, business model descriptions of 100 randomly chosen start-up firms were coded using a DDBM framework derived from literature, comprising six dimensions with 35 features. Subsequent application of clustering algorithms produced six different types of DDBM, validated by case studies from the study’s sample.

Findings
The taxonomy derived from the research consists of six different types of DDBM among start-ups. These types are characterised by a subset of six of nine clustering variables from the DDBM framework.

Practical implications
A major contribution of the paper is the designed framework, which stimulates thinking about the nature and future of DDBMs. The proposed taxonomy will help organisations to position their activities in the current DDBM landscape. Moreover, framework and taxonomy may lead to a DDBM design toolbox.

Originality/value
This paper develops a basis for understanding how start-ups build business models capture value from data as a key resource, adding a business perspective to the discussion of big data. By offering the scientific community a specific framework of business model features and a subsequent taxonomy, the paper provides reference points and serves as a foundation for future studies of DDBMs.
Managing supply chain uncertainty with emerging ethical issues
Authors: Simangunsong Elliot , Hendry Linda C. , Stevenson Mark 
Published: September 2016

Purpose
The purpose of this paper is to empirically investigate effective management strategies for 14 sources of supply chain uncertainty, with a particular emphasis on uncertainties or strategies that involve ethical issues.

Design/methodology/approach
Manufacturing strategy theory, underpinned by alignment and contingency theory, is used as the theoretical foundation. Multi-case study data are collected from 12 companies in the Indonesian food industry, including four focal manufacturers, four first-tier suppliers, and four first-tier customers (retailers).

Findings
Within the context of appropriately aligned management strategies to address 14 sources of uncertainty, three ethical issues are empirically identified: first, collusion amongst suppliers to ration supplies and increase prices; second, unethical influences on government policy; and third, “abuse” of power by large retailers at the expense of smaller competitors. Joint purchasing is argued to be a key strategy for combatting the first of these ethical issues.

Research limitations/implications
The study is limited to the Indonesian food industry, and so further research is needed in other cultures/contexts.

Practical implications
Management strategies that aim to reduce an uncertainty at its source lead to better overall supply chain performance than strategies that merely cope with uncertainty, which only have an impact on firm-level performance.

Social implications
The ethical issues identified have implications for fair negotiations between customers and suppliers.

Originality/value
This study is unique in its in-depth case study-based empirical investigation of the management of multiple supply chain uncertainties; and in its discussion of ethical issues in this context.
