The purpose of this paper is to show how controlled exposure of electromagnetic fields toward bearing steel vulnerates the microstructure. The ability of Barkhausen Noise signal processing is used for detecting phenomena such as dislocation and subgrain formation processes as the beginning of later failures.

A Barkhausen noise signal measurement equipment is used for detecting subsurface distress of 100Cr6 as a function of the applied electromagnetic and mechanical stress. Barkhausen noise signal is mathematically processed by use of fractal dimension analysis.

The paper cleary reveals significant impact of electromagnetic field in junction with mechanical loading. Electromagnetic impact depends on the magnitude of the field.

Research limitations are given by the fact that in real field applications, e.g. wind power plants, bearings are exposed by multiple influences and the methodology is not applicable to those conditions.

The methodology can be applied to real field applications in condition monitoring systems. Up to now, no reasonable on‐line measurement is in use determining sub surface fatigue phenomena. The paper hence, reveals the possibility to raise condition monitoring into a new perspective.

The use of Barkhausen noise signal processing, as presented here, is original with respect to real field applications, such as wind power plants with a high demand in condition monitoring, especially off‐shore plants.

Mounting empirical evidence shows that engagement in social network sites (SNSs) could have a negative impact on users’ personal well-being. However, studies of the undesirable effects of SNS use have not examined SNSs as a channel for users to share consumption information and experiences. To extend prior research, this study aims to examine the impact of consumption-oriented engagement (COE) in SNSs on young adult consumers’ personal well-being in terms of anxiety and self-esteem, as well as excessive spending.

Surveys were the primary means of data collection from a sample of young college students (N = 900). Moderated hierarchical regression was used to test the hypotheses.

COE is positively associated with anxiety and excessive spending and negatively associated with self-esteem. Social comparison mediates these relationships, and individuals’ materialistic values moderate the mediation.

This study demonstrates the psychological and behavioral outcomes of consumer socialization via digital media among young adult consumers. It introduces and empirically validates social comparison as a theoretical explanation for the effects of COE. In addition, it validates materialistic values as a personal trait that moderates the effects of COE.

The study validates COE as a key precursor to the well-being of young adult users of SNSs and social comparison as the mediator. With this understanding, public policies can be designed to mitigate the root cause of the negative impact of SNS use.

Findings shed light on the negative repercussions of engagement in SNSs in the consumption domain and provide an impetus for educators, researchers and policymakers to make further efforts to gain a thorough understanding of the pitfalls of social media use.

In a quest to meet increasing pressure to incorporate environmental and sustainability factors due to the legislations and growing public awareness, companies are rethinking of strategizing their supply chain network to take control of the reverse flow of products as well. This growing interest has also led to tremendous growth in publications occurring in several reputed journals in the last few years. In this context, the purpose of this article is to perform a systematic literature survey of recent and state-of-the-art papers in order to draw insights and highlight the future directions.

This paper has selected and reviewed 204 papers published from the year 2002–2017. The papers were collected from the web of science and Google scholar database which have the DOI number. The selected papers were then categorized into main five core areas of RSC management namely reverse supply chain (RSC), Reverse Logistics (RL), Remanufacturing, Closed-Loop Supply Chain (CLSC) and Product Recovery Systems (PRS) and then analyzed with great detail. Finally, the research gaps that were identified from the study have been highlighted for future research opportunities.

This paper would serve as a roadmap to the managers who wish to align their forward and reverse supply chains for overall growth and development. It provides an in-depth knowledge on RSC to the researchers working in this domain. The scholars would be able to identify the areas of RSC which have been already addressed and the areas which remain unaddressed.

This paper presents a systematic literature survey of state-of-the-art papers that was published in the reputed journal in the area of RSC. Total 204 numbers of papers which were published in the reputed journals between 2002 and 2017 are reviewed, categorized and analysed to draw the opportunities and future research direction in the area of RSC.

Previous research on salesperson-customer proximity has yielded mixed results, with some studies documenting positive proximity effects on shopping responses and others demonstrating the reverse. To reconcile such mixed findings, this paper aims to test whether and how salesperson proximity influences a series of key customer outcomes in actual retail settings using sample sizes that are considerably larger than most former investigations.

We conducted two high-powered field studies (N = 1,312) to test whether salesperson‐customer proximity influences consumers’ purchase behavior and store loyalty. Moreover, we investigated whether the short-term effects on purchase behavior were moderated by the extent to which the consumption context had a clear connection to consumers’ own bodies.

Salesperson proximity increased purchase incidence and spending in consumption contexts with a bodily basis (e.g. clothes, beauty, health), suggesting that consumers “buy their way out” in these contexts when a salesperson is violating their personal space. If anything, such proximity had a negative impact on consumers’ purchase behavior in contexts that lacked a clear bodily connection (e.g. building materials, furniture, books). Moreover, the link between proximity and consumer responses was mediated by discomfort, such that a salesperson standing close-by (vs farther away) increased discomfort, with negative downstream effects on shopping responses. Importantly, the authors found opposite proximity effects on short-term metrics (purchase incidence and spending) and long-term outcomes (store loyalty).

Drawing on the nonverbal communication literature and theories on processing fluency, the current work introduces a theoretically relevant boundary condition for the effects of salesperson-customer proximity on consumers’ purchase behavior. Specifically, the bodily basis of the consumption context is discussed as a novel moderator, which may help to explain the mixed findings in this stream of research.

Salesperson-customer proximity may serve as a strategic sales tactic to improve short-term revenue in settings that are closely tied to consumers’ own bodies and characterized by one-time purchases. However, as salesperson proximity was found to be associated with lower store loyalty, irrespective of whether the shopping setting had a bodily basis, the risk of violating consumers’ personal space may have costly consequences from a long-term perspective.

The present field studies make three central contributions. First, we introduce a novel moderator for proximity effects in various sales and service settings. Second, we test the focal hypotheses with much higher statistical power than most existing proximity studies. Finally, we document that salesperson-customer proximity ironically yields opposite results on short-term metrics and long-term outcomes, thus underscoring the importance of not solely focusing on sales effectiveness when training frontline employees.

When evaluating a booking enquiry, hosts rely on peer-to-peer (P2P) accommodation platforms (P2PAP) to make an informed decision. Consequently, accepting or rejecting a booking is influenced by the capacity of the P2PAP to convey to hosts valuable information about guests. This study aims to explain hosts’ task performance in short-term rentals (e-rentals).

The proposed model explains hosts’ task performance in e-rentals as a combination of task-specific user capabilities and technology capabilities. The model was tested using the partial least square path modelling technique.

Task-specific user capabilities of covert observation and interrogation were found to have a positive influence on task performance. Moreover, a moderation effect of representation on the relationship between self-disclosure and task performance was found to be significant, yet contrary to the one hypothesized.

The findings from this study help to develop the concept of task-specific user capabilities in shaping task performance.

The significance of physician-user interaction has been widely acknowledged in offline and online healthcare consultation. However, limited attempts have been made to explore the influence of physician-user interaction on users' perceived service quality (PSQ) in the mobile context. Based on the literature on physician-user interaction and media synchronicity theory, this study proposes a theoretical model where the interactive factors common across the offline, online and mobile context, i.e. physicians' informational support and emotional support, the interactive factors unique in the mobile context, i.e. physicians' response speed and voice service, and the interaction between the two categories of interactive factors predict users' PSQ in mobile consultation.

This study collects consultation records between 25,225 users and 738 physicians from a leading Chinese mobile consultation application, and employs linear regression to verify the proposed theoretical model.

Physicians' informational, emotional support, response speed and voice service are found to have significant positive impacts on users' PSQ. Besides, physicians' response speed strengthens the positive impacts of physicians' informational and emotional support on users' PSQ, while physicians' voice service weakens the positive link between physicians' informational support on users' PSQ.

This study contributes to the antecedents for users' PSQ in mobile consultation by identifying unique interactive factors in the mobile context, and highlighting the individual and interaction effects of different physician-user interactive factors. Besides, this study employs novel methods, which leverages text classification and text pattern recognition to more accurately depict physicians' online behaviors based on objective communication records.

The purpose of this paper is to investigate the factors influencing work readjustment of Vietnamese returnees who used to study and/or work in a developed country and are currently working in different positions in their home country.

Data for this study were collected through a survey of 433 returnees using both paper-based and online surveys. Multiple regression was used to test the relationships in the model.

The findings show that while the length of time spent overseas, work expectations and subjective norm significantly affect work readjustment, the influences of age, gender and length of time since return on work readjustment are not supported.

The findings provide useful insights for home country government and managers of returnees developing repatriation programs that help returnees deal with the issue of poor work readjustment.

Empirical studies on cross-cultural re-entry adjustment of both self-initiated repatriates and international students are scarcely investigated. Most prior studies focused on individual factors (such as gender, age, duration in overseas and since return), research on the effect of work expectation on work readjustment is still scant. Most prior studies focused on examining the relationship between work expectation and work readjustment of company repatriates, however, this relationship in the context of returnees, especially in the Asia-Pacific region, has not been investigated. Furthermore, this study is the first to examine the influence of subjective norm on work readjustment of returnees.

This article reports the results of a theoretically‐based, empirical study which incorporates the paradigm of relationship marketing. Using a sample of organizational buyers, this study examines the influence of salesperson customer‐oriented behavior on the development of buyer‐seller relationships. Integral to this investigation, a measure of buyer‐seller relationship development is generated and evaluated for its reliability and validity. Findings from this study indicate a strong and significant influence between the customer‐oriented behavior of salespeople and the development of customer relationships. The results of this study and the discussion of the implications begin to provide valuable understanding into the antecedents of relationship development and relationship management. The results of this study and their implications for salespeople, managers, and researchers are discussed along with limitations and recommendations for future research.

Sustainability and the search for solutions that are both efficient and ecologically sound (eco-efficient) have become topics of great interest. However, companies seeking to develop supply chain solutions that are eco-efficient are often hampered by their ability to control the wider supply chain and they may need to draw on external support from logistics service providers (LSPs). This paper aims to explore the innovative strategies undertaken by LSPs in the eco-efficiency arena and the logistics and learning capabilities needed to achieve eco-efficiency in supply chains.

The insights derived from a systematic literature review approach to identify the most relevant articles to be included in the analysis represented the starting point for building the authors empirical investigation, based on case studies with in-depth interviews to investigate the phenomenon under consideration and to explore trends and evolving paradigms.

The systematic literature review enriches the existing literature by drawing on three bodies of knowledge, i.e. logistics service providers, eco-efficiency and logistics innovation, and putting them into a single framework. The findings from the interviews suggest that although LSPs are well placed to implement innovative initiatives for eco-efficiency there is a range of inhibitors that prevent major change programmes.

The research reported in this paper is exploratory and limited in its scope. It is based on in-depth interviews within six companies. However, it does provide a platform from which more detailed research may be conducted.

The managerial implications arising from the research offer a wide range of current practices in sustainability, from which strategic and operative directions to compete can be derived.

There is little existing literature that addresses the innovative strategies undertaken by LSPs in influencing and moving supply chains towards eco-efficiency and hence the present paper is meant to help fill this gap.

Customer service conversations are becoming increasingly digital and automated, leaving service encounters impersonal. The purpose of this paper is to identify how customer service agents and conversational artificial intelligence (AI) applications can provide a personal touch and improve the customer experience in customer service. The authors offer a conceptual framework delineating how text-based customer service communication should be designed to increase relational personalization.

This paper presents a systematic literature review on conversation styles of conversational AI and integrates the extant research to inform the development of the proposed conceptual framework. Using social information processing theory as a theoretical lens, the authors extend the concept of relational personalization for text-based customer service communication.

The conceptual framework identifies conversation styles, whose degree of expression needs to be personalized to provide a personal touch and improve the customer experience in service. The personalization of these conversation styles depends on available psychological and individual customer knowledge, contextual factors such as the interaction and service type, as well as the freedom of communication the conversational AI or customer service agent has.

The article is the first to conduct a systematic literature review on conversation styles of conversational AI in customer service and to conceptualize critical elements of text-based customer service communication required to provide a personal touch with conversational AI. Furthermore, the authors provide managerial implications to advance customer service conversations with three types of conversational AI applications used in collaboration with customer service agents, namely conversational analytics, conversational coaching and chatbots.
