The effects of arm swing amplitude and lower-limb asymmetry on gait stability
Authors: Hill Allen , Nantel Julie 
Published: June 2019

AbstractChanges to arm swing and gait symmetry are symptomatic of several pathological gaits associated with reduced stability. The purpose of this study was to examine the relative contributions of arm swing and gait symmetry towards gait stability. We theorized that actively increasing arm swing would increase gait stability, while asymmetric walking would decrease gait stability. Fifteen healthy, young adults (23.4 ± 2.8 yrs) walked on a split-belt treadmill under symmetric (1.2 m/s) and asymmetric walking (left/right, 5:4 speed ratio) with three different arm swings: held, normal, and active. Trunk local dynamic stability, inter-limb coordination, and spatiotemporal gait variability and symmetry were measured. Active arm swing resulted in improved local trunk stability, increased gait variability, and decreased inter-limb coordination (p < .013). The changes in local trunk stability and gait variability during active arm swing suggests that these metrics quantify fundamentally different aspects of stability and are not always comparable. Split-belt walking caused reduced local trunk stability, increased gait variability, and increased lower limb asymmetry (p < .003). However, the arm swing symmetry was unaffected by gait asymmetry, this suggests that deficits in gait stability in pathological gaits may be linked to increases in gait asymmetry rather than increases in arm swing asymmetry.

Published: June 2019

Purpose
The purpose of this paper is to study the repeatability of path manufacturing in the drop on demand inkjet printing process and the influences of environmental and application factors on path resistance.

Design/methodology/approach
Paths were printed as multiline paths in packets one-, two- and three-layer paths on polyimide substrates using nanoparticle silver ink. The sintering conditions were determined experimentally. The paths were subjected to climatic and shock exposures and to bending processes. The resistance, profile and width of the paths were measured and analyzed. The temperature distribution for electrically heated paths was measured to identify the defects.

Findings
This research shows the repeatability of printing processes and identifies the sources that cause diversification in path parameters after the whole technological process. The influence of shock, climatic and mechanical exposures on path electrical properties is indicated. An effective method for identifying defects thermally is shown.

Research limitations/implications
The research could have limited universality by arbitrarily use of substrate material, ink, printhead, process parameters and kind of sample exposures.

Practical implications
The research includes practically useful information about the width, thickness, defects and resistances and their changes during a typical application for a path printed with different technological parameters.

Originality/value
This research presents the results of original empirical research on problems concerning the manufacture of paths with uniform parameters and shows how path parameters will change under exposures that may occur in a typical application. The research combines both production and application aspects.
Stability investigations based on two-port describing functions
Authors: Ladvanszky Janos 
Published: June 2019

Purpose
Stability of a nonlinear, tuned amplifier has been investigated based on the describing function method. On stability, this paper means global asymptotic stability. The tuned amplifier comprises a saturated amplifying device with feedback and two resonators, at the input and the output. Describing function method here means introduction of the two-port describing functions.

Design/methodology/approach
Describing function method is applied, extended for two ports. Results from complex analysis and matrix algebra are heavily used. The two resonators have identical resonant frequency and bandwidth. Instability is represented by non-vanishing output perturbation for zero-input perturbation. Applying a simple transistor model with saturation and feedback, stability is analyzed in the form of output voltage as a function of input voltage.

Findings
Two-port scattering and admittance describing functions have been introduced. At a certain input voltage amplitude, instability appears in the form of unwanted sidebands, then at a higher input voltage, instability disappears, in good agreement with experiments. The hand calculated stability limits are in good agreement with the computer analysis.

Originality/value
The paper is based on an early publication of the author (Baranyi and Ladvánszky, 1984). Here, the full material is presented, explained step by step, extended and revised. All neglections that were earlier made in the author’s paper have been avoided here. This paper has significant tutorial value as well.

Authors: Cui Li , Jiang Haiyang , Deng Hepu , Zhang Tao 
Published: June 2019

Purpose
The purpose of this paper is to investigate how the diffusion of food safety information through social media affects customers’ purchase intentions in China. This leads to the identification of the critical factors that impact the purchase intention of individual consumer through the diffusion of food safety information using social media in China.

Design/methodology/approach
A research model is proposed based on a comprehensive review of the related studies. Such a model is then tested and validated using structural equation modeling based on the survey of 199 individuals who have experience in purchasing food products online while having social media accounts.

Findings
The study reveals that friend recommendation and perceived risk directly affect consumers’ purchase intentions and opinion leader recommendation, quality of information, credibility of information and demand for information indirectly affect consumers’ purchase intentions through the diffusion of food safety information using social media in China.

Originality/value
This study is the first of this kind in China for exploring the critical factors that affect consumers’ purchase intentions through the diffusion of food safety information using social media. The findings of the study are significant for the government and food enterprises to make a full use of the advantages of social media to improve the communication of food safety information in ensuring the safety of the food supply in China.
Research on the simplified vehicle window buffeting noise with a modified LRN CLES model using a transition-code based method
Authors: Chen Zhen , Gu Zhengqi , Wang Zhonggang 
Published: June 2019

Purpose
This paper aims to propose a precise turbulence model for vehicle aerodynamics, especially for vehicle window buffeting noise.

Design/methodology/approach
Aiming at the fact that commonly used turbulence models cannot precisely predict laminar-turbulent transition, a transition-code-based improvement is introduced. This improvement includes the introduction of total stress limitation (TSL) and separation-sensitive model. They are integrated into low Reynolds number (LRN) k-ε model to concern transport properties of total stress and precisely capture boundary layer separations. As a result, the ability of LRN k-ε model to predict the transition is improved. Combined with the constructing scheme of constrained large-eddy simulation (CLES) model, a modified LRN CLES model is achieved. Several typical flows and relevant experimental results are introduced to validate this model. Finally, the modified LRN CLES model is used to acquire detailed flow structures and noise signature of a simplified vehicle window. Then, experimental validations are conducted.

Findings
Current results indicate that the modified LRN CLES model is capable of achieving acceptable accuracy in prediction of various types of transition at various Reynolds numbers. And, the ability of this model to simulate the vehicle window buffeting noise is greater than commonly used models.

Originality/value
Based on the TSL idea and separation-sensitive model, a modified LRN CLES model concerning the laminar-turbulent transition for the vehicle window buffeting noise is first proposed.
Homotopy perturbation method for peristaltic motion of gold-blood nanofluid with heat source
Authors: Ebaid Abdelhalim , Aljohani Abdulrahman F. , Aly Emad H. 
Published: June 2019

Purpose
This paper aims to investigate the impacts of the gold nanoparticles on the peristaltic flow and heat transfer of blood in the presence of heat source. This element has been chosen because on comparing with the other common nanoparticles, gold nanoparticles are preferred due to their unique properties in absorbing the temperature when a heat source exists.

Design/methodology/approach
On simplifying the governing equations under the assumption of long-wavelength and low-Reynolds number approximations, the resulted system has been solved by applying the homotopy perturbation method. Then, detailed physical discussion has been introduced through several plots while focusing on the consequences of the current results on the treatment of cancer.

Findings
The present results revealed that the heat source has a great effect on the blood velocity, blood temperature and concentration of the gold nanoparticles within the artery/vein cavity when represented as asymmetric channel. Moreover, the accuracy of the current solutions was validated through several plots of the remainder error for each studied phenomenon.

Originality/value
The current idea gives some light on the attempts of using the gold nanoparticles in the treatment of cancer and therefore may lead to possible applications for diagnosis/therapy of the human cancer. To the best of authors’ knowledge, this is novel, very efficient and applicable.
Simulation of phase separation in a Van der Waals fluid under gravitational force with Lattice Boltzmann method
Authors: Fogliatto Ezequiel Oscar , Clausse Alejandro , Teruel Federico Eduardo 
Published: June 2019

Purpose
This paper aims to assess the accuracy of Lattice Boltzmann method (LBM) for numerical simulation of the stratification of a Van der Waals (VdW) fluid subjected to a gravity field and non-uniform temperature distribution. A sensitivity analysis of the influence of the pseudopotential parameters and the grid resolution is presented. The effect of gravity force on interface densities, density profiles and liquid volume fraction is studied.

Design/methodology/approach
The D2Q9 multiple-relaxation-time pseudopotential LBM for two-phase flow is proposed to simulate the phase separation. The analytical solution for density profiles in a one-dimensional problem is derived and used as a benchmark case to validate the numerical results.

Findings
The numerical results reproduce the analytical density profiles with great accuracy over a wide range of simulation conditions, including variations of the gravity and temperature fields. Particularly, the numerical simulations are able to represent the effect of gravity on the existence and position of the liquid–vapor boundary of an ideal pure substance in thermodynamic equilibrium. The sensitivity of the results to variations of the calibration parameters of the VdW pseudopotential was assessed.

Research limitations/implications
The numerical simulations were performed assuming a VdW fluid in a 2-D cavity with one periodic direction for which analytical solutions for benchmarking purposes are possible to obtain.

Originality/value
The following fundamental question is addressed: Is the pseudopotential LBM capable of simulating accurately the liquid–vapor equilibrium under gravity forces and temperature gradients? Moreover, regarding that the pseudopotential model requires the calibration of several internal parameters to achieve thermodynamic consistency, the sensitivity of the results to variations of these parameters is assessed.
Scale to measure tourist value of destination restaurant service
Authors: Kim Og Yeon , Seo Sunhee , Nurhidayati Vieta Annisa 
Published: June 2019

Purpose
The purpose of this study is to develop a measurement scale to explain how international tourists, as consumers at destination restaurants, evaluate their dining experiences.

Design/methodology/approach
The measurement scale was developed using a three-stage process: initial item generation, scale development and scale evaluation. A total of 369 self-administered questionnaires validated the developed scale.

Findings
The results showed five dimensions of value of destination restaurant services: service quality value, authentic experience value, emotional experience value, social value and utility value. The scale, comprising 40 items, was reliable and valid for assessing the value of destination restaurant services.

Research limitations/implications
This scale revealed new items that help explain the value of various destination restaurant services among international tourists. The developed scale could be used to extend the research model with antecedents of value and consequences of value for destination restaurant services.

Practical implications
Considering the popularity of food tourism among international tourists, the developed scale should be useful in assessing how tourists value destination restaurant services, thereby helping restaurant managers create effective marketing strategies.

Originality/value
This study contributes with a new, reliable and valid measurement scale that was specifically developed to address the unique value of destination restaurant services.
Rebuilding a global brand under crisis – case of a global brand Maggi
Authors: Srivastava Rajesh Kumar 
Published: June 2019

Purpose
The purpose of this paper is to study whether the controversy because of brand crisis based on quality had any impact on consumer brand equity, brand image, brand reliability, brand perception of quality, perceived value, brand sentiments and purchase behavior.

Design/methodology/approach
The research methodology consisted of two types of data: primary and secondary data. The secondary research consisted of social media brand sentiments and financial analysis. The primary research focused on perception study of brand quality, consumer brand equity, brand reliability, brand image, purchase and brand switch behavior.

Findings
Maggi used social media extensively to address the issue and re-build the brand reliability and confidence among its users. Communication strategy adopted by focusing on the past experience of consumers and using them as a spokesperson generated a positive sentiment towards the brand under crisis.

Research limitations/implications
While Maggi suffered the backlash because of the controversy across the length and breadth of India and was banned in a number of states, the author could conduct the primary research only in one city of the state of Maharashtra, Mumbai. The effectiveness of the survey was impacted because of the geographic limitations the author faced while collecting the responses. The survey would have definitely been more effective, with responses collected from different states and with more number of respondents. Fishbein is very old, from the 1980s, even though this theory has met the test of time. Application of the effect of experiences on experiential perceptions and how this influences value through networking could have been used to explain the same.

Practical implications
An important implication of this paper’s findings for practice, therefore, is that brands should incessantly strive to maintain the consumers’ level of trust, as it is essential for the preservation of the brand equity after a crisis. Crisis-stricken brands should safeguard their reputations from the negative effects of crises. It is even more important for any brand to act appropriately when the cause of the crisis is attributed to its actions and processes. Managers have to address the quality of products in case of brand crisis for restoring trust, image and reliability in the brand. Right type of communication to right targeted consumers will help in the restoration of the image, trust on the brand and bring back loyal customers. Managers have to build brand equity on a regular basis, as a strong brand can recover faster as seen from this paper.

Originality/value
This paper helps to upgrade the knowledge and understanding of the impact of the controversy on brand equity and image and how the crisis management strategy can be adopted to regain the mind share and equity. This paper will help the brands in the future to know how a crisis can be managed efficiently by drawing a cue from the strategies implemented by Maggi.
Promoting the image of a historic city for sustainable cultural tourism: the case of Tlemcen Capital of Islamic Culture 2011
Authors: Kherbouche Somia , Djedid Abdelkader 
Published: June 2019

Purpose
Focussing on the event “Tlemcen Capital of Islamic Culture 2011”, the purpose of this paper is to examine the changing perception of the city’s image, assess its durability and determine its relationship with the development of sustainable cultural tourism.

Design/methodology/approach
This research is tested by an empirical study that combines a qualitative and a quantitative approach. The qualitative study is based on semi-directive interviews, whereas quantitative study is based on statistics from the Wilaya Tourism Department.

Findings
The results of this study indicate first of all that the perception of the city’s image by the inhabitants is not static and that it follows the same process of evolution of the perception of the image by tourists but in relation to other factors such as awareness and age. The second result shows that the sustainability of the image must be verified both inside and outside to achieve sustainable cultural tourism.

Originality/value
This study is in line with previous research with another point of view on the city’s image and another case study which is the historical city of Tlemcen. It serves to examine the evolution of the perception of the city’s image produced by the event and to assess its sustainability.
Strategies and measures directed towards overtourism: a perspective of European DMOs
Authors: Eckert Christian , Zacher Daniel , Pechlaner Harald , Namberger Philipp , Schmude Jürgen 
Published: June 2019

Purpose
Due to both the new quality and intensity overtourism discussions have received, it is time to examine the question concerning the consequences this development has on destination level and how destinations can adjust their strategies for future development. This is especially important to consider, since overtourism can be seen as a fundamental issue for tourism development. First measures taken within destinations show that reactions are taking place, e.g. through access restrictions of frequently visited places. The purpose of this paper is to identify future-oriented strategies and to derive concrete measures in order to deal with overtourism on a destination level.

Design/methodology/approach
In total, 19 qualitative interviews with European destination managers were conducted and evaluated via the qualitative analysis method GABEK® with WinRelan® software.

Findings
The results show that various stakeholders are involved in overtourism, with the destination management organization being the central actor to deal with issues. It is challenging to choose between different strategies and measures, which always have to be considered in relation to the specific conditions of a destination and the perception level of overtourism. In order to face current developments, the initiation of a stakeholder dialog can be seen as a promising factor, but also as a challenging task.

Originality/value
Currently, a “wait-and-see-attitude” exists, where well-known destinations are cited as negative examples, but a serious examination related to one’s own destination has not yet been developed. This consideration should be seen as a prerequisite for future-oriented destination development, which takes the local population into account.
Extending the double jeopardy and duplication of purchase laws to the wine market
Authors: Wilson Damien , Winchester Maxwell 
Published: June 2019

Purpose
This study aims to understand the market structure and explore the applicability of recognised generalisations to a European wine retail market. The study considers whether brands in European wine retailing follow the established double jeopardy and duplication of purchase laws, with the aim of investigating their limits so as to identify where market partitions are evident.

Design/methodology/approach
The researchers conducted a cross-purchasing analysis within the wine category over a 12-month period, using a customer panel of n = 25,000 across a chain of independent retail stores in an English-speaking European country. Analysis was conducted across purchases of the top 20 wine brands.

Findings
Consumer wine repurchase results confirmed a double jeopardy pattern. These consumers’ wine repurchasing behaviour from other top-20 wine brands could have generally been predicted in line with the duplication of purchase law. However, a small number of exceptions to these patterns were identified, suggesting the existence of market partitions.

Research limitations/implications
In this study, market partitions were evident for selected brands, a wine region and a common grape variety, Sauvignon blanc. Such exceptions illustrate that consumer purchase patterns can deviate from predictions, for a small number of brands in a consumer goods category than would be expected given duplication of purchase law norms. Such anomalies to empirical generalisations help demonstrate boundary conditions and lead further research on the market conditions required for such anomalies to be evident. Implications suggest that further research should be conducted on the product features creating market partitions.

Practical implications
The findings suggest that regional wines can appeal to a more clearly partitioned customer group within the clientele, but that substitution is noted among brands within regions.

Originality/value
To the best of the authors’ knowledge, this is the first study to use a large sample consumer database to determine the generalisability of two well-established empirical generalisations: the double jeopardy and duplication of purchase laws, to the wine retail market. Knowing these are applicable to the wine retail markets allows wine producers and retailers to predict expected repurchase and cross-purchasing norms.
