The purpose of this paper is to reveal the assumptive concept of internationalization because it is discussed and understood in the international business (IB) literature. This paper develops a framework to reconceptualize internationalization in the context of global value chain (GVC) and sustainability. Based on this conceptual framework, this paper aims to formulate interrelated propositions to define internationalization.

This paper reviews the assumptive conceptualization process based on empirical evidence obtained through qualitative, illustrative and descriptive content analysis methods. Through the collection and qualitative content analysis of milestone papers, this paper demonstrates the fragmentation of the concept of internationalization. This paper reviews the evolving nature of the concept of internationalization, analyzing the accumulative issues associated with defining internationalization, as well as its potential future development.

This paper introduces a dynamic perspective on the evolving nature of the concept of internationalization and argue there is a need to reconceptualize internationalization in the context of the GVC and sustainability.

After reviewing the context in which the term “internationalization” has been applied and taking into consideration the current trends in the IB, this paper formulates an updated definition of the term internationalization. This paper offers a viewpoint on the future direction of the concept of internationalization in light of the growing importance of sustainability within IB.

Biofeedback is used for regulating vestibular adaptation and balance by providing real-time stimulus to the individual during physical activities. This study aimed at (1) developing a wearable device, which tracks balance, counts the number and the direction of balance losses and provides haptic biofeedback through real-time vibration stimulus (2) investigating device efficacy on an adolescent medulloblastoma patient during static and dynamic tasks.

A 16-year-old medulloblastoma patient used the device during 10-m walking and single-leg stance tests. The knee joint kinematics and the number and direction of balance losses were recorded for “with” and “without” biofeedback conditions.

The device helped regulate the knee joint kinematics and reduce the number of balance losses of the medulloblastoma patient. The knee joint movement pattern similarity of the control subject was highly correlated (R² = 0.997, RMSE = 1.232). Conversely, medulloblastoma patient knee joint movement pattern similarity was relatively weak (R² = 0.359, RMSE = 18.6) when “with” and “without” biofeedback conditions were compared. The number of balance losses decreased when the medulloblastoma patient was guided with biofeedback.

The major limitation of this pilot study is the lack of a large and homogeneous number of participants. The medulloblastoma patient used the device while walking after she was given enough time to get used to the tactile biological feedback, so the long-term effect of the device and biofeedback guidance were not investigated. Additionally, the potential desensitization with prolonged use of the device was not evaluated.

Biofeedback reduced the number of balance losses; additionally, the knee joint movement pattern was regulated during static and dynamic tasks. This device can be integrated into the physical therapy of patients with balance, vestibular and postural control impairments.

This is compact and has an easy-to-wear design, patients, who have balance and postural control impairments, can practically use the device during their activities of daily living.

The device promotes physical activity adaptation and regulates gait through continuous and real-time balance control. Its design makes it simple for the user to wear it beneath clothing while using the sensor.

The digital revolution has changed consumer–service provider interaction, spawning a new generation of FinTech. This paper analyzes consumers' reactions to artificial intelligence (AI) (vs human) decisions.

The authors tested their predictions by conducting two experimental studies with FinTech consumers (n = 503).

The results reveal that consumers' responses to AI (vs human) credit decisions depend on the type of credit product. For personal loans, the rejection by an AI provider triggers higher levels of satisfaction compared to a credit analyst. This effect is explained via the perceived role congruity. In addition, the findings reveal that consumers’ rejection sensitivity determines how they perceive financial services role congruity.

To the best of the authors' knowledge, this research is the first to jointly examine AI (vs human) credit decisions in FinTech and role congruity, extending prior research in the field.
