The purpose of this work is to optimize the monitoring of vibrations on dynamometric test rigs for railway brakes. This is a quite demanding application considering the continuous increase of performances of high-speed trains that involve higher testing specifications for brake pads and disks.

In this work, authors propose a mixed approach in which relatively simple finite element models are used to support the optimization of a diagnostic system that is used to monitor vibration levels and rotor-dynamical behavior of the machine. The model is calibrated with experimental data recorded on the same rig that must be identified and monitored. The whole process is optimized to not interfere with normal operations of the rig, using common inertial sensor and tools and are available as standard instrumentation for this kind of applications. So at the end all the calibration activities can be performed normally without interrupting the activities of the rig introducing additional costs due to system unavailability.

Proposed approach was able to identify in a very simple and fast way the vibrational behavior of the investigated rig, also giving precious information concerning the anisotropic behavior of supports and their damping. All these data are quite difficult to be found in technical literature because they are quite sensitive to assembly tolerances and to many other factors. Dynamometric test rigs are an important application widely diffused for both road and rail vehicles. Also proposed procedure can be easily extended and generalized to a wide value of machine with horizontal rotors.

Most of the studies in literature are referred to electrical motors or turbomachines operating with relatively slow transients and constant inertial properties. For investigated machines both these conditions are not verified, making the proposed application quite unusual and original with respect to current application. At the same time, there is a wide variety of special machines that are usually marginally covered by standard testing methodologies to which the proposed approach can be successfully extended.

The purpose of this paper is to develop a load detection method for domestic induction cooktops. The solution aims to minimize its impact in the converter power transmission while enabling the estimation of the equivalent electrical parameters of the load. This method is suitable for a multi-output resonant inverter topology with shared power devices.

The considered multi-output converter presents power devices that are shared between several loads. Thus, applying load detection methods in the literature requires a halt in the power transfer to ensuring safe operation. The proposed method uses a complementary short-voltage pulse to excite the induction heating (IH) coil without stopping the power transfer to the remaining IH loads. With the current through the coil and the analytical equations, the equivalent inductance and resistance of the load is estimated. The precision of the method has been evaluated by simulation, and experimental results are provided.

The measurement of the current through the induction coil as a response to a short-time single-pulse voltage variation provides enough information to estimate the load equivalent parameters, allowing to differentiate between no-load, non-suitable IH load and suitable IH load situations.

The proposed method provides a solution for load detection without requiring additional circuitry. It aims for low power transmission to the load and ensures zero-voltage switching and reduced peak current even in no-load cases. Moreover, the proposed solution is extensible to less complex converters, as the half bridge.

This study aims to provide a holistic review of social media influencers (SMIs) research based on a unique approach of bibliometric analysis and content analysis between 2011 and 2020. The review examines the main influential aspects, themes and research streams to identify research directions for the future.

The sample selection and data collection were done from the Scopus database. The sample dataset was refined based on the inclusion and exclusion criteria to determine the final dataset of 183 articles. The dataset was exported in the BibTeX format and then imported into the BiblioShiny app for bibliometric analysis. The content analysis was done following the theory-context-methodology framework.

The several findings of this study include (1) Co-word analysis of most used keywords; (2) Longitudinal thematic evolution; (3) The focus of the research papers as per the theory-context-methodology review protocol are persuasion knowledge model, fashion and beauty industries, Instagram and content analysis, respectively; and (4) The network analysis of the research studies is known as the co-citation analysis and depicts the intellectual structure in the domain. This analysis resulted in four clusters of the research streams from the literature and two emergent themes (Chen et al., 2010)

In general, the previous reviews in the area are either domain, method or theory-based. Thus, this study aims to complement and extend the existing literature by presenting the overall picture of the SMI research with the help of a unique combined approach and further highlighting the trends and future research directions based on the findings of this study.

This study aims to develop a talent selection model for learning organizations capable of connecting two groups, candidates in a talent hiring process and managers of the hiring company, in a reliable process, promoting organizational learning and increasing employee satisfaction.

This paper integrates egalitarian principles, an artificial intelligence mechanism founded on stable matching algorithms, and evaluating critical soft skills to enhance recruitment practices within learning organizations. The authors conduct a numerical real-world application in Python to showcase the model’s effectiveness. Five candidates were evaluated for five job positions. Moreover, 26 soft skills were analyzed by the five company leaders, relating them to the requirements of each job position and by all candidates, as a self-assessment process.

The model promoted egalitarian talent management because it motivates the candidates to choose the preferred position in a company, and the employers hire the best candidate. It is satisfactory for all participants in a company’s hiring process if the parties intend to be fair and egalitarian. The benefits of the process can be considered isolated (parties’ satisfaction) or a part of a company’s effort to stimulate an egalitarian culture in organizational values.

The information generated by the model is used to refine its selection process and improve its understanding of the job requirements and candidate profiles of the company. The model supports this idea, using the concepts of indifference, stability, egalitarianism and the soft skills required and identified to be more effective and learn about themselves.

This paper discusses an egalitarian point of view in the recruitment process. It is satisfactory for all participants in a company’s hiring process if the parties intend to be fair and egalitarian. The process’s benefits can be considered part of a company’s effort to stimulate an egalitarian culture in organizational values.

This paper brings an excellent future perspective and points to the company’s development of talent retention. The model simultaneously solves the evolution of talent management processes through new technologies and soft skills emerging in the postpandemic scenario.

This study aims to discuss the current context, scope and impacts of a metaverse in the hospitality and tourism industry. Although existing literature discussed the potentials of the metaverse in this context, the ways the metaverse work is still being defined and accessing a complete metaverse is still not yet possible. This existing knowledge will become increasingly sophisticated and complex as developments in the metaverse continue, eventually contributing to a knowledge gap in knowledge, and its implications in shaping how the future digital environment should take form.

This work is based on a critical reflection of the existing developments and applications of the metaverse. Drawing from authors’ experiences, and synthesis of existing works and narratives, this work discusses the applications of the metaverse, critical factors for considerations and applications of the metaverse and proposes the way forward for potential users.

The metaverse provides new opportunities for the hospitality and tourism industry but the impact of the technology may not be felt immediately. The real challenge lies in developing a responsible digital environment for users and suppliers. Although the aspects to be considered are many, a lack of preparedness is a great obstacle.

This paper provides a comprehensive evaluation of how the metaverse can be applied in the hospitality and tourism sector aiming to provide diverse stakeholders insights into the associated opportunities and pitfalls.

To the best of the authors’ knowledge, this paper is among the first attempts to critically reflect on the possibilities of the metaverse, and contributes to the discussion on the attributes of the metaverse for tourism and hospitality (e.g. SSIs, decentralization) and includes discussion on special needs users, sustainable usage and climate change, and presents several agendas for further actions.

This case study allows students to appreciate the value of standard operating procedures in customer management. This case study emphasises the role of employees in delivering superior customer experience. This case study explores many facets of customer experience, reputation, social class membership and standard operating procedures (SOPs). Students will be able to apply theories of customer experience, behavioural psychology and service dimensions relevant to the airline industry. After completing this case study, students will be able to do the following:1. Evaluate the value of SOPs in Customer ManagementThis case study refers to the need for adhering to SOPs to deal with complex situations. Students will be able to evaluate whether compliance to SOPs could have helped Air India avoid the crisis or was it possible that a culture of absolute commitment to customer wellbeing could have prevented the crisis.2. Apply the theory of defensive attribution in customer grievance handling. Discuss if reducing customer effort in getting their problem solved can result in superior customer service.The victim had attributed the blame for not insisting on filing a complaint to the crew. Air India crew had defended their actions or lack of it by stating that they had followed the rule book. Students will be able to appreciate the need for a swift redressal mechanism to protect the self-image and self-esteem of the person/group involved. They will also understand that customer service interactions designed to solve customer problems swiftly and easily can be a very simple dictum to guide all employees in their decision-making while handling a customer complaint.

3. Evaluate the relationship between customer satisfaction and customer experience and examine the value of net promoter score (NPS) to study customer satisfaction.

Air India Airlines was catering to varied customer groups such as the Indian diaspora, large student population pursuing education abroad, first-time flyers and the rising middle class with travel aspirations. Customer expectations vary across segments and change over their lifetime. Airline staff must trace customer corridors and deliver on customer expectation across the touch points that matter to them to ensure meaningful and relevant service delivery. Students will have an opportunity to evaluate the NPS in measuring customer satisfaction and debate whether it is a sufficient metric to guide the organisation on delivering and monitoring customer experience.

4. Examine why reputation risk management and not crisis management should be the focus of Air India in delivering superior customer service because nearly 70%–80% of market value for a company comes from its intangible assets such as brand equity and reputation.

Students will discuss crisis management i.e. handling the threat to reputation after it has occurred and reputation risk management i.e. proactively managing potential threats to its reputation by taking timely actions to avoid or mitigate it. There are three factors (reputation reality gap, changing beliefs and expectation and weak internal coordination) that determine reputational risks. Students can evaluate this model to determine if Air India should address these three factors to manage its reputation proactively.

This case study is set around an incident that happened on 26 November 2022, on Air India flight bound for Delhi from New York when an inebriated 34-year-old man had peed on a 72-year-old woman. The perpetrator of the crime had walked free, and the victim was left dissatisfied with how the cabin crew had handled her ordeal. Air India Airlines was launched in 1932 by industrialist JRD Tata and nationalised in 1953. In 2021, Tata Group acquired the 90-year-old Air India from the Government of India for $2.4bn (INR 18,000 crore) and appointed Campbell Wilson as chief executive officer and managing director. The incident brought to the fore the customer management issues that Wilson had to address. First on the list of Air India’s turnaround plan was delivering “exceptional customer experience”. How was it going to achieve it because the Indian aviation ecosystem lacked infrastructure such as airports, airspace, competition and customer preference-based services? There was also shortage of pilots, engineers, technicians, air-traffic controllers and technocrats to occupy positions within security agencies and regulatory bodies. With Air India’s acquisition, the Tata Group had to find innovative solutions to deal with decades of internal neglect, non-performance and labour union problems. This case study is relevant to address real issues of customer experience, consumer psychology, reputation risk management and standard operating procedures in service management.

This case is suitable for both undergraduate and postgraduate level students of business management. It can also be used for training service personnel of aviation industry.

This exploratory study aims to integrate both quantitative and qualitative methods to examine the influence of contemporary university dining attributes and practices on student patronage.

First, a review of the extant literature on-campus dining in universities was conducted. Second, innovative practices of on-campus dining facilities of a large public university were identified. Finally, student perceptions of those practices were examined using a mixed method approach.

The review of literature uncovered 49 articles across 35 years on key topics such as food waste, healthy eating, and service evaluation. From site tours and interviews with related personnel, 40 innovative on-campus dining practices were identified.

Importance ratings revealed cleanliness of the environment, fresh fruit and vegetables, and digitally enabled ordering, as the top three highest rated practices. Factor analysis unveiled six factors that students find important: food diversity, good standards, innovativeness, quick options, menu variety, and fish and seafood. The thematic analysis further revealed four overarching themes (convenience, familiarity, food offerings, and value) and 13 subthemes which complemented the quantitative results.

In addition to shedding post-pandemic light on students’ dining needs, it highlights the paucity of theory used to support extant studies and suggests a novel theoretical underpinning.

This study investigated two key aspects: (1) how a hospital bundles limited resources for preventive care performance and (2) how to develop IS capabilities to enhance preventive care performance.

A case study method was adopted to examine how a hospital integrates its limited resources which leads to the need for resource bundles and an understanding of IS capabilities development to understand how they contribute to the delivery of preventive care in a Malaysian hospital.

This research proposes a comprehensive framework outlining resource-bundling and IS capabilities development to improve preventive care.

We acknowledge that the problem of transferring and generalizing results has been a common criticism of a single case study. However, our objective was to enhance the reader’s understanding by including compelling, detailed narratives demonstrating how our research results offer practical examples that can be generalized theoretically. The findings also apply to similar-sized public hospitals in Malaysia and other developing countries, facing challenges like resource constraints, HIS adoption levels, healthcare workforce shortages, cultural and linguistic diversity, bureaucratic hurdles, and specific patient demographics and health issues. Further, lessons from this context can be usefully applied to non-healthcare service sector domains.

This study provides a succinct strategy for enhancing preventive care in Malaysian public hospitals, focusing on system integration and alignment with hospital strategy, workforce diversity through recruitment and mentorship, and continuous training for health equity and inclusivity. This approach aims to improve resource efficiency, communication, cultural competence, and healthcare outcomes.

Efficiently using limited resources through HIS investment is essential to improve preventive care and reduce chronic diseases, which cause approximately nine million deaths annually in Southeast Asia, according to WHO. This issue has significantly impacted the socioeconomic development of developing countries.

This research refines resource orchestration theory with new mechanisms for resource mobilization, extends IS literature by identifying how strategic bundling forms specialized healthcare IS capabilities, enriches preventive care literature through actionable resource-bundling activities, and adds to HIS literature by advocating for an integrated, preventive care focus from the alignment of HIS design, people and institutional policies to address concerns raised by other research regarding the utilization of HIS in improving the quality of preventive care.

This case was developed via primary data collected from personal (one to one) interview with the CEO and founder of Dialogue in the Dark Malaysia (Dialogue Malaysia), Stevens Chan. With Stevens’ contact, the authors also conducted personal interviews with Kaye Chan (co-founder and wife of Stevens Chan), Lynn Foo (project manager since inception until early 2022) and Dr Foo Yin Fah (academic researcher in social entrepreneurship and advisor for Dialogue Malaysia). Secondary data included reports on visually impaired context in Malaysia, Dialogue Malaysia’s annual reports and online articles. Prior to the primary data collection, the authors obtained ethics approval from the University Human Ethics Committee (Project ID: 35461).

This case narrative focuses on Stevens Chan, a blind social entrepreneur who champions the empowerment of the disabled and marginalised community. Through a social franchising model, Stevens founded Dialogue in the Dark Malaysia in 2012. As a social start-up, Stevens showcases the strengths of blind and visually impaired individuals through transformative experiential encounters and reimagining future possibilities. Although there are constant challenges in securing financial and human capital, Stevens never lacks psychological capital, characterised by hope, self-efficacy, optimism and resilience. His vision is to educate society on the power of empathy (and not sympathy) and to create a holistic experience of celebrating diversity and inclusion through an innovative discovery centre, where the elderly and the disabled community (including the deaf, mute and those with mobility issues) share their lives with the public through fun activities. However, the future of this social enterprise is uncertain, and this case invites participants to embark on this journey with Stevens to uncover future pathways for growth and social impact.

The case is tailored for higher level undergraduates and entry-level and mid-level managers of executive education programs.

Recently, powerful instruments for biomedical engineering research studies, including disease modeling, drug designing and nano-drug delivering, have been extremely investigated by researchers. Particularly, investigation in various microfluidics techniques and novel biomedical approaches for microfluidic-based substrate have progressed in recent years, and therefore, various cell culture platforms have been manufactured for these types of approaches. These microinstruments, known as tissue chip platforms, mimic in vivo living tissue and exhibit more physiologically similar vitro models of human tissues. Using lab-on-a-chip technologies in vitro cell culturing quickly caused in optimized systems of tissues compared to static culture. These chipsets prepare cell culture media to mimic physiological reactions and behaviors.

The authors used the application of lab chip instruments as a versatile tool for point of health-care (PHC) applications, and the authors applied a current progress in various platforms toward biochip DNA sensors as an alternative to the general bio electrochemical sensors. Basically, optical sensing is related to the intercalation between glass surfaces containing biomolecules with fluorescence and, subsequently, its reflected light that arises from the characteristics of the chemical agents. Recently, various techniques using optical fiber have progressed significantly, and researchers apply highlighted remarks and future perspectives of these kinds of platforms for PHC applications.

The authors assembled several microfluidic chips through cell culture and immune-fluorescent, as well as using microscopy measurement and image analysis for RNA sequencing. By this work, several chip assemblies were fabricated, and the application of the fluidic routing mechanism enables us to provide chip-to-chip communication with a variety of tissue-on-a-chip. By lab-on-a-chip techniques, the authors exhibited that coating the cell membrane via poly-dopamine and collagen was the best cell membrane coating due to the monolayer growth and differentiation of the cell types during the differentiation period. The authors found the artificial membrane, through coating with Collagen-A, has improved the growth of mouse podocytes cells-5 compared with the fibronectin-coated membrane.

The authors could distinguish the differences across the patient cohort when they used a collagen-coated microfluidic chip. For instance, von Willebrand factor, a blood glycoprotein that promotes hemostasis, can be identified and measured through these type-coated microfluidic chips.
