Abstract
Purpose
One of the main causes of long-term prosthetic abandonment is the lack of ownership over the prosthesis, which was caused mainly by the absence of sensory information regarding the lost limb. The period where the patient learns how to interact with a prosthetic device is critical in rehabilitation. This ideally happens within the first months after amputation, which is also a period associated with the consolidation of brain changes. Different studies have shown that the introduction of feedback mechanisms can be crucial to bypass the lack of sensorial information. To develop a biofeedback system for the rehabilitation of transfemoral amputees – controlled via electromyographic (EMG) activity from the leg muscles – that can provide real-time visual and/or vibratory feedback for the user.
Design/methodology/approach
The system uses surface EMG to control two feedback mechanisms, which are the knee joint of a prosthetic leg of a humanoid avatar in a virtual reality (VR) environment (visual feedback) and a matrix of 16 vibrotactile actuators placed in the back of the user (vibratory feedback). Data acquisition was inside a Faraday Cage using an OpenEphys® acquisition board for the surface EMG recordings. The tasks were performed on able-bodied participants, with no amputation, and for this, the dominant leg of the user was immobilized using an orthopedic boot fixed on the chair, allowing only isometric contractions of target muscles, according to the Surface EMG for Non-Invasive Assessment of Muscles (SENIAM) standard. The authors test the effectiveness of combining vibratory and visual feedback and how task difficulty affects overall performance.
Findings
The authors' results show no negative interference combining both feedback modalities and that performance peaked at the intermediate difficulty. These results provide powerful insights of what can be accomplished with the population of amputee people. By using this biofeedback system, the authors expect to engage another sensory modality in the process of spatial representation of a virtual leg, bypassing the lack of information associated with the disruption of afferent pathways following amputation.
Research limitations/implications
The authors developed a showcase with a new protocol and feedback mechanisms showing the protocol's safety, efficiency and reliability. However, since this system is designed for patients with leg amputation, the full extent of the effects of the biofeedback training can only be assessed after the evaluation with the amputees, and the results obtained so far establish a safe and operational protocol to accomplish this.
Practical implications
In this study, the authors proposed a new biofeedback device intended to be used in the preprosthetic rehabilitation phase for people with transfemoral amputation. With this new system, the authors propose a mechanism to bypass the lack of sensory information from a virtual prosthesis and help to assimilate visual and vibrotactile stimuli as a cue for movement representation.
Social implications
With this new system, the authors propose a mechanism to bypass the lack of sensory information from a virtual prosthesis and help to assimilate visual and vibrotactile stimuli as a cue for movement representation.
Originality/value
The authors' results show that all users were capable of recognizing both feedback modalities, both separate and combined, being able to respond accordingly throughout the tasks. The authors also show that for a one-session protocol, the last difficulty level imposed a greater challenge for most users, explained by the significant drop in performance disregarding the feedback modality. Lastly, the authors believe this paradigm can provide a better process for the embodiment of prosthetic devices, fulfilling the lack of sensory information for the users.

Abstract
Purpose
The value chain is an essential management tool for the elaboration of strategic organizational planning. However, there are few published works providing methods for the development of value chains. This research aims to present a model to develop the value chain for the public sector.
Design/methodology/approach
Action research was used with case study in the evaluation step.
Findings
This research presents a model for value chain development along seven steps, covering data collection planning to the formalization of final product acceptance. The model suggests executing these seven steps in three iteration levels: operational, tactical and strategic. Through case studies, six practical insights were also highlighted in this work.
Research limitations/implications
Given the absence of related work, one of the limitations is the lack of comparison with other methods of value chain development in the public sector.
Originality/value
There are practical guides to value chain development in the public sector; however, to the best of authors’ knowledge, such guides have not been developed using research methods. In the literature, no works provide details on how value chain can be developed in the public sector. In addition, the constraints of face-to-face contacts during the COVID-19 pandemic led the research team to conduct remotely the model's development and evaluation in the case studies. The model presents elements that enable value chain development without face-to-face contact between the execution team and public institution's stakeholders.

Abstract
Purpose
Reducing inequity in accessing healthcare among rural and remote populations remains a problem. Internationally, eHealth is now touted as a potential solution, with a range of diverse approaches and impacts. Yet, the equity gains of implementing eHealth are often not realized due to a lack of effective strategies for citizen participation. The purpose of this paper is to present the background to, and results of, a multidisciplinary eHealth assistance project in a remote region of the Brazilian Amazon, highlighting the importance of citizen participation within planning processes.
Design/methodology/approach
The project was conducted in three phases – pre‐mission, mission, and post‐mission. Discussions were held between health teams and local community leaders, and were coordinated by government health organizations in partnership with the Amazon State University. A multidisciplinary team visited five remote communities in the Brazilian Amazon, where participants underwent clinical assessment using eHealth technologies within pharmacy, cardiology, dermatology, and/or odontology. Analysis and second opinion were provided by relevant specialists and the results were delivered electronically to local healthcare teams.
Findings
A total of 111 patients were evaluated with an average age of 54 years. There were several important findings following specialist second opinion, which improved the quality of care they received. These comprise identifying drug interactions and patients requiring further investigation for cardiological and dermatological complaints, including suspected malignancy.
Research limitations/implications
Due to a breakdown in communication, data from the post‐mission phase are lacking, particularly regarding treatment outcomes. Furthermore, the authors did not perform an analysis of cost‐effectiveness. If eHealth technologies are to become part of routine clinical practice it is important that the financial implications are acceptable.
Originality/value
This project demonstrates how equity can be designed for with a multidisciplinary approach to eHealth activities in rural and remote environments within Brazil. Such activities typically focus on one particular area, yet primary healthcare facilities see patients with a variety of problems.

Abstract
Purpose
At a time when tourism is embarking on the path to recovery from the COVID-19 crisis, this paper aims to put forward a set of principles guiding the development of tourism to enable global society to become more inclusive and sustainable.
Design/methodology/approach
This paper adopted a descriptive design using views and data mainly published by 11 international organisations and specialised agencies between March and mid-June 2020. Content analysis was carried out to enable the research to identify features and the presence of challenges for tourism within international organisations’ documents and leaders’ speeches to compare them.
Findings
The results revealed that there are five key principles that may have a significant impact on tourism development, suggesting that these could be adopted for building a more inclusive and sustainable economy, while mitigating the impact of the COVID-19 crisis.
Practical implications
Adopting the five key principles recommended in this paper can help tourism to emerge stronger and in a more sustainable way from COVID-19 or other future crises. Equally, this can incite changes in policies, business practices and consumers’ and locals’ behaviours with a view to building a truly sustainable sector.
Originality/value
This study helps to reconfirm existing knowledge in the COVID-19 context by highlighting five guiding principles that can help tourism players to respond to this crisis disruption and future ones via transformative innovation. In doing so, these will also be contributing to the achievement of the ideals and aims of the Sustainable Development Goals.

Abstract
Purpose
This research has been carried out to look into the long run impact of the controls on capital inflows imposed during the years 1998‐2001 in Malaysia. The paper intends to capture the long‐term impact of capital controls in changing the composition of capital flows into Malaysia and to examine whether the controls have been able to divert the short‐term capital inflows to longer‐term investments.
Design/methodology/approach
The autoregressive first differenced ordinary least square models have been used to examine whether the controls have been able to divert the short‐term capital inflows to longer‐term investments.
Findings
The capital controls have been successful in the short run in switching some of the short‐term capital inflows into longer‐term portfolio investments, without jeopardizing the Malaysian investment environment in the longer‐term. Such controls did not have an impact on the decisions of foreign investors in the long run even if the rating agencies downgraded the Malaysian investments immediately after the controls were imposed. This paper suggests that capital flows into Malaysia were more a result of interest rate differentials between the domestic and the US interest rates and hardly depended on the Malaysian risk adjusted returns.
Research limitations/implications
One of the limitations of this research is the ephemeral nature of the econometric analysis. All the variables, except government spending, are first differenced, in order to overcome the problem of spurious regression. However, while taking the first difference, there is a possibility of losing valuable long‐term relationship between the capital flows and the explanatory variables. Further, the analysis was carried out without much reference to the derivative market, which might have disguised some of the capital flows.
Social implications
Capital controls are adopted to prevent the volatility in domestic markets caused due to capital flight. The capital flight has huge macroeconomic implications on a society, including unemployment, interest rate volatility and subsequent economic slowdown and recession. If adopted with an intention to provide a temporary breathing space, it might help the countries manage their domestic imbalances.
Originality/value
This paper provides a fresh look at the implications of capital controls with longer‐term data that also include the period after the controls were withdrawn. The study is expected to be independent of market distortions, which might arise with narrow time frames that cover periods during and/or immediately after the crisis.

Abstract
Globalization has become such an all-encompassing concept that it is almost meaningless. However, most scholars recognize that the term conveys in some manner or form a shrinkage of time and space such that events happening in one part of the world have the potential to impact other locales (Giddens, 1999; Held, 1991). Beyond this most basic meaning, it is hard to find any agreement on what the term actually conveys or when in fact the world actually entered a global age (Morrow & Torres, 2000). Given the vagueness of globalization as a concept, the challenge then is to be as clear as possible in discussing various forces related to globalization that may impact a particular phenomenon under study. In the case of this chapter, the phenomenon of interest is university transformation in the developing world.

Abstract
Purpose
The purpose of this study is to review the critical success factors (CSFs) of street food destinations, given the limited attention awarded to such research in the food and beverage sector.
Design/methodology/approach
An interpretivist approach was used to merge CSFs from street vending and culinary tourism perspectives, to develop a draft framework for analysing CSFs for street food destinations. In total, 64 cities that appeared in the first 20 webpage results of a Google search, using 4 keywords, formed the population. A purposive sample of seven destinations (Bangkok, Marrakesh, Mexico City, Istanbul, Hong Kong, Portland and Singapore City) was used. A content analysis method was used to review webpages, journal articles and government reports of the destinations, based on the modified list of CSFs.
Findings
The availability of diverse street food resources and cultures, coupled with rich historic city cores that sustain street food vending, in some destinations, are very important CSFs. The presence and extent of regulatory enforcement were also key in others. Empirical research is, however, required to corroborate the draft framework to create a body of knowledge for further research in the field.
Originality/value
The study examines how leading street food destinations have instituted the CSFs required for street food provision.

This study explored health insurance coverage of genetic testing and potential factors associated with precision medicine (PM) reimbursement in Thailand.
Abstract
Purpose
This study explored health insurance coverage of genetic testing and potential factors associated with precision medicine (PM) reimbursement in Thailand.
Design/methodology/approach
The study employed a targeted review method. Thirteen PMs were selected to represent four PM categories: targeted cancer therapy candidate, prediction of adverse drug reactions (ADRs), dose adjustment and cancer risk prediction. Content analysis was performed to compare access to PMs among three health insurance schemes in Thailand. The primary outcome of the study was evaluating PM test reimbursement status. Secondary outcomes included clinical practice guidelines, PMs statement in FDA-approved leaflet and economic evaluation.
Findings
Civil Servant Medical Benefits Scheme (CSMBS) provided more generous access to PM than Universal Coverage Scheme (UCS) and Social Security Scheme (SSS). Evidence of economic evaluations likely impacted the reimbursement decisions of SSS and UCS, while the information provided in FDA-approved leaflets seemed to impact the reimbursement decisions of CSMBS. Three health insurance schemes provided adequate access to PM tests for some cancer-targeted therapies, while gaps existed for access to PM tests for serious ADRs prevention, dose adjustment and cancer risk prediction.
Originality/value
This was the first study to explore the situation of access to PMs in Thailand. The evidence alerts public health insurance schemes to reconsider access to PMs. Development of health technology assessment guidelines for PM test reimbursement decisions should be prioritized.

Abstract
Purpose
Retail store loyalty is essential to the survival and success of a retailer. The intangible benefits provided by the social exchange in-store influence the way consumers consider their relationships with the retailer. However, its relationships with social proximity and cultural factors are not clear. Therefore, this article investigates the effects of specific cultural dimensions on loyalty behaviour, as well as the mediating role of social proximity on the relationship investigated.
Design/methodology/approach
This research is based on an empirical investigation undertaken in Thailand with a sample of 636 respondents. Two retail chains were investigated (Big C and Tesco). Structural equation modelling was used to test the research model and a series of research hypotheses.
Findings
The results reveal that uncertainty avoidance and long-term orientation have positive direct effects on loyalty, while collectivism does not. Furthermore, social proximity significantly mediates the effects of collectivism and long-term orientation on customer loyalty. These findings show that Thailand is a specific emerging market in which retail chains should adapt their loyalty programme accordingly.
Practical implications
The cultural differences could be used for segmentation strategy for retailers to engage customers in a relationship with the hypermarket. Social proximity is an efficient lever to build loyalty in Thailand. In addition, retailers could utilise certainty and steadiness message as a way to build shopper loyalty.
Originality/value
This research underlines the social, human dimension that consumers seek, which is opposed to the online purchase. Specifically, this study highlights the mediating role of social proximity between the relationship of cultural variables and loyalty in the retail context. Additionally, this research displays the direct and positive effects of culture on retail loyalty. That is, this paper enhances how culture and shopper-retail staff interaction can be managed to achieve store loyalty.
