Bearings are critical components used to support loads and facilitate motion for rotating and sliding parts of the machinery. Bearing malfunctions can cause catastrophic failures. Hence, failure analysis and endeavors to improve bearing performance are essential discussions for worldwide designers, manufacturers and end users of vital machinery. This study aims to investigate a type of roller bearing from the railway industry with premature failures. The task arises because locomotives’ maintenance and service life quality are vital to railway operations while providing transportation services for the nation. To assist in maintaining the designated locomotives, the present study scrutinizes the causes of failure of heavy-duty roller bearings from locomotive bogie axleboxes.

It is intended to inspect this bearing service life and statistically scrutinize its design parameters to reveal the failures’ shortcomings and origins. The significant measures include examinations of their failures’ primary and vital factors by comparing them with a real-life service history of 16 roller bearings of the same type. The bearings come from the axleboxes of a locomotive bogie with an axle load of 20 tons. The bearing loads are estimated using the EN13104 standard document and confirmed by the finite element method using ABAQUS engineering software. To validate the finite element modeling results, the bearings’ stress analysis is performed using the Hertzian contact theory that demonstrated perfect conformity. The said methods are also used to search for the areas susceptible to failures in these bearings. With the inclusion and exploitation of the bearing maintenance conditions and the logbook recordings of the locomotives for the past seven years, the critical cause for this type of bearing’s failures is surveyed and discussed.

With the inclusion and exploitation of the bearing maintenance conditions and the logbook recordings of the locomotives for the past seven years, the critical cause for this type of bearing’s failures is surveyed and discussed. As a crucial result, it is found that deprived maintenance and inadequate lubrication are the root causes of the loss of the selected bearings.

For the designated locomotives, the origins of the heavy-duty roller bearing failures and its design shortcomings are revealed by examining and comparing them with a real-life service history of many of the same types of bearings. The novelty of the research is in using the combination of the methods mentioned above and its decent outcome.

This study aims to examine the role of hospitableness towards refugees, as embraced by local hosts, in engendering positive social outcomes, including fostering favourable attitudes and empathy towards refugees, satisfaction from hosting refugees in private dwellings and advocacy for hosting them.

Rooted in the contact theory and drawing on a hospitality social lens framework, the study uses a mixed-methods approach using a sequential quantitative-qualitative design to understand the interface between hospitableness, attitudes and empathy towards refugees, satisfaction from hosting refugees in private dwellings and advocacy for hosting them. A conceptual model is proposed and tested using 160 valid surveys collected from individuals hosting Ukrainian refugees in Slovakia. SEM-PLS is used to test the proposed model. A total of 25 in-depth interviews with Slovakian individuals hosting refugees in private dwellings were also conducted to explain and further explore the initial quantitative results.

The findings indicate that hospitableness has a positive effect on attitudes towards refugees, fosters a sense of empathy and results in satisfaction from hosting refugees. Interestingly, while hospitableness per se does not directly affect advocacy for hosting refugees, it does so indirectly via favourable attitudes towards refugees and satisfaction from the hosting experience. While qualitative findings largely support and further explain the quantitative results, interesting insights are also obtained.

The study advocates that hospitableness should be addressed through a social lens beyond its traditional commercial boundaries. Several implications for policymakers, NGOs and other stakeholders involved in hosting refugees are proposed. Overall, policies need to be oriented towards harnessing the power of refugee hosting schemes, thus increasing the role of hospitableness in addressing societal challenges such as the refugee crisis.

While not new, private hosting of refugees has recently gained momentum following the outbreak of the Ukrainian refugee crisis. In spite of some valuable research delving into hosting experiences from the refugees’ and hosts’ perspectives, this research stream is notably fragmented and largely exploratory. Specifically, there seems to be no comprehensive understanding of how hospitableness towards refugees, as embraced by hosts, can engender positive social outcomes, including fostering favourable attitudes and empathy towards refugees, satisfaction from hosting refugees and advocacy for hosting refugees in private dwellings. Overall, hospitality research is notably biased towards commercial settings, focusing on instrumental benefits rather than societal outcomes. This study focuses on the societal outcomes of hospitableness as a tool to address the refugee crisis.

This paper aims to design, develop and validate an instrument to measure employer branding by considering existing employee perceptions.

In this systematic research, the predominant factors of employer branding are identified through Pareto analysis; using structured questionnaire information and data collected from 423 employees. The number of items and dimensions was reduced by conducting exploratory factor analysis (EFA) and validated extracted dimensions using confirmatory factor analysis (CFA) using statistical software (SPSS-21). The designed scale was verified by applying relevant statistical techniques, including a multicollinearity test, construct validity, content validity, divergent validity, convergent validity and reliability test. Structural equation modeling (SEM) was performed using AMOS, to explore the interrelationship between the dimensions of the scale.

Considering the perception of existing employees, seven factors along with 24 items scale were designed and developed to measure the employer branding. The identified seven factors are; career development opportunities; compensation and benefits; corporate social responsibility; training and development; work environment; organizational culture; and work-life balance. The proposed model explains a total variance of 70.35% and the model fit indices are within the acceptable range, validity and statistical reliability are established for seven dimensions of employer branding.

Employer branding is studied from existing employee perspective by collecting responses from the employees of the IT sector only.

This validated scale is valuable for practitioners and academicians. The proposed dimensions in the scale may help practitioners explore the impact on the outcomes of organizations such as employee commitment, employee retention, employee satisfaction and total productivity. This novel instrument helps to measure employees' perception of their employers. Further, the authors identify the gaps and accordingly plan strategies to attract and retain the talented workforce.

The authors believe that this novel measuring instrument is comprehensive and the first of its kind. Employer branding has been modeled using SEM analysis by considering the perceptions of the present employees.

This study aims to examine the relationship between knowledge management and career development in an era characterized by high levels of youth unemployment and a demand for specialized skills. Despite the increasing transition to a knowledge-based economy, there is a significant gap between young people’s skills and career readiness, necessitating an in-depth analysis of the role of knowledge management at the individual, organizational and national levels.

The authors conducted a qualitative study using the theory-context-characteristics-methodology approach based on a systematic literature review. The authors created an ecological framework for reflecting on knowledge management and career development, arguing for a multidisciplinary approach that invites collaboration across sectors to generate innovative and reliable solutions.

This study presents a comprehensive review of the existing literature and trends, noting the need for more focus on the interplay between knowledge management and career development. It emphasizes the need for businesses to promote the acquisition, storage, diffusion and application of knowledge and its circulation and exchange to create international business human capital.

The findings may help multinational corporations develop managerial training programs and recruitment strategies, given the demand for advanced knowledge-based skills in the modern workspace. The study also discusses the influences of education, experience and job skills on business managers’ performance, guiding the future recruitment of talents.

To the best of the authors’ knowledge, this review is among the first to assess the triadic relationship between knowledge management, career development and the global unemployment crisis. The proposed multidisciplinary approach seeks to break down existing silos, thus fostering a more comprehensive understanding of how to address these ongoing global concerns.

The purpose of this study is to develop a conceptual model explicating the development of expatriate social capital and its influence on expatriate effectiveness in terms of knowledge transfer and adjustment. Drawing upon social capital theory and weak tie theory, we elucidate the process through which expatriate social capital facilitates expatriate knowledge transfer and adjustment via greater access of role information and social support.

This study reviews and distills research on expatriate social capital development and proposes a conceptual model of expatriate effectiveness and suggests potential research avenues for global mobility scholars.

This study contributes to the understanding of the development of expatriate social capital in the host country and its impacts on expatriate effectiveness as a process. With regard to expatriates’ social capital accumulation, this study also highlights the important but less-known role of accompanying spouse/family members as expatriates’ weak tie enablers. We articulate a framework that outlines the sources of social capital for expatriates and the processes through which social capital transmits (via expatriates’ access to role information and social support) and then enhances expatriate effectiveness. This conceptual model aims to establish a basic “roadmap” for use by practitioners and researchers.

Before the proposed conceptual model can be theoretically refined or extended by future research, its veracity needs to be tested empirically. Although we do not incorporate “time,” “personal characteristics” and “context” in our model, we recognize their potential importance and urge future researchers to incorporate them in studying the role of social capital on expatriate effectiveness.

A conceptual model is presented that enables multinational corporations (MNCs) to map their current (and future) strategies to enhance expatriate effectiveness by further strengthening the expatriate social capital.

Drawing upon social capital theory and weak tie theory, this paper links various sources of expatriate social capital to expatriates’ access to role information and social support in supporting expatriate effectiveness. From this, several avenues of future research are drawn.

The purpose of this study is to develop a model for investigating the sharing of harmful messages by employees using social media using the conspiracy theory from a socio-legal perspective. This study also examines the moderating role of different demographic parameters such as age, gender and education toward sharing harmful messages using social media.

Using the conspiracy theory and social impact theory as the foundation of this study, the authors developed theoretical model and validated it using the structural equation modeling technique with 342 participants from various organizations across Europe and Asia. The study also used different statistical measures to understand the demographic impacts toward sharing harmful messages.

It was found that epistemic, existential and social motives significantly and positively influence employees’ inappropriate message-sharing and seeking behavior, which in turn influences them to share harmful messages on social media. The study also indicates that there are some moderating impacts of employee demography toward sharing harmful messages using social media platforms.

This study investigates the antecedents of sharing harmful messages using social media by employees. The present study could be useful for the organizations leaders as well as policymakers and legal fraternity. The study uses a limited number of feedback to validate the model. Also, this is a cross-sectional study which is another limitation of this study.

This study has proposed and validated a theoretical model by using the conspiracy theory as well as the social impact theory which is unique. Moreover, this study adds value to the existing literature on the harmful impacts of social media and its societal impacts. Besides, the validated model of this study has a high explanatory power which is another uniqueness of this study.

The paper presents a mathematical problem involving quasistatic contact between a thermo-electro-viscoelastic body and a lubricated foundation, where the contact is described using a version of Coulomb’s law of friction that includes normal damped response conditions and heat exchange with a conductive foundation. The constitutive law for the material is thermo-electro-viscoelastic. The problem is formulated as a system that includes a parabolic equation of the first kind for the temperature, an evolutionary elliptic quasivariational inequality for the displacement and a variational elliptic equality for the electric stress. The author establishes the existence of a unique weak solution to the problem by utilizing classical results for evolutionary quasivariational elliptic inequalities, parabolic differential equations and fixed point arguments.

The author establishes a variational formulation for the model and proves the existence of a unique weak solution to the problem using classical results for evolutionary quasivariational elliptic inequalities, parabolic difierential equations and fixed point arguments.

The author studies a mathematical problem between a thermo-electro-viscoelastic body and a lubricated foundation using a version of Coulomb’s law of friction including the normal damped response conditions and the heat exchange with a conductive foundation, which is original and requires a good understanding of modeling and mathematical tools.

Social media sites facilitate electronic word of mouth (eWOM) communication among consumers of diverse cultures and ethnicities. Based on the theory of planned behaviour (TPB), the present research proposes a conceptual framework for minority consumers' engagement in eWOM associated with the mainstream culture. The model incorporates social capital and social interaction as key factors that affect cross-cultural eWOM communication between minority and mainstream consumers. This research also aims to explore the responses of minority consumers to eWOM communications originating with members of the majority group.

A structural equation modelling (SEM) procedure was applied to data collected from social media (Facebook) users (N = 539) from two minority communities: Israeli Arab and Israeli Ultra-Orthodox Jewish minorities.

The findings show that: (a) minority consumers' engagement with eWOM is indirectly related to social capital, (b) this relationship is mediated by minority consumers' attitudes and their subjective norms regarding eWOM engagement with dominant cultural groups, (c) social interaction of minorities with the dominant culture enhances the influence of social capital on eWOM engagement and (d) behavioural engagement with eWOM varies across cultural minorities, depending on the minority group’s unique cultural characteristics.

The findings have managerial implications for practitioners who use social media in their marketing and business activities, as they demonstrate that the effectiveness of eWOM communication is contingent on the cultural characteristics of the ethnic minority consumer groups being targeted by managers.

The present research contributes to the theory of consumer engagement by demonstrating that engagement is contingent on the intercultural social context in which eWOM is communicated.

Business models (BMs) are becoming increasingly crucial for value creation in the healthcare sector. The study explores the conceptualization and application of BM concepts within the healthcare sector and investigates their evolution in emerging economies (EEs) and developed economies (DEs). This study aims to uncover these two contexts' shared characteristics and unique variances through a comparative analysis.

The paper systematically investigates and consolidates the literature on healthcare by employing the antecedents, decisions and outcomes (ADO) framework and finally examines 71 shortlisted articles published between 2003 and 2022.

The recognition of the BM within healthcare is increasing, both in EEs and DEs. EEs prioritize value creation and capture through cost efficiency, while DEs focus on innovation. Key theories employed include a resource-based view, the network theory and the theory of innovation. Case studies are commonly used as a methodology. Further research is needed to explore the decisions and outcomes of BMs.

The study adopts stringent filtration and keyword criteria, potentially excluding relevant research. Future researchers are encouraged to broaden their selection criteria to encompass a more extensive range of relevant studies.

Beyond comparing and highlighting gaps in BMs between EEs and DEs, benchmarking DE's healthcare business models (HBMs) helps healthcare organizations in EEs align their practices, mitigate risks and establish efficient healthcare systems tailored to their specific contexts. The study adopts stringent filtration and keyword criteria, potentially excluding relevant research. Future researchers are encouraged to broaden their selection criteria to encompass a more extensive range of relevant studies.

The study analyzes HBMs using an SLR framework perspective and provides practical implications for academicians and practitioners to enhance their decision-making.

This study aims to contribute to social identity theory in tourism by exploring the reflections of Chinese tourists visiting North Korea and how they negotiate their intergroup identity in this similar-others destination.

Data were collected via online platforms and in-depth interviews. A qualitative approach, i.e. thematic analysis, was used to analyse the two sets of data.

Results showed that when encountering North Koreans perceived as similar others amid the social, economic and political environments in which they were embedded, Chinese tourists often categorised themselves as ordinary tourists, preferentially treated tourists and vicarious tourists based on intergroup similarities to North Koreans. They also performed intergroup comparison to boost their self-esteem at group and collective levels and developed corresponding strategies to generate distinct emotional group commitments.

It is recommended that destinations reinforce the friendly and unique relationship with their similar-others source markets to improve their attractiveness. Destinations should also strive to enhance the experience of tourists from their similar-others markets by arousing their positive collective-level affection, emotional resonance and nostalgic memories and avoiding negative emotions.

This study offers a theoretical framework analysing the features of tourists’ social identities while visiting a similar-others destination, contributing to our understanding of the interactive and contingency nature of social identity in tourism, and responding to the call for addressing the broader social contexts in which tourists’ group identity is embedded.

本文致力于探索赴朝中国游客的反思以及他们在这个“类似他者”目的地如何协商群际身份, 以对旅游领域的身份认同理论做出贡献。

本文运用主题分析方法; 资料来源于网络文本和深度访谈。

当中国游客面对被视为“类似他者”的朝鲜人时（具有相似的社会、经济和政治环境）, 他们会根据与朝鲜人的群际相似性, 将自我分类为“普通游客”、“受优待者”和“过来人”三类。此外, 他们还会通过群际比较来提高群体层面和集体层面的自尊, 并且采取对应策略以产生不同的群体承诺。

本文提出了一个分析游客访问“类似他者”目的地时的社会认同的理论框架, 对理解旅游中的社会认同的互动性和偶然性做出了贡献, 并响应了在考察游客群体认同时关注其所处的更广泛的社会背景的呼吁。

目的地应该强化它们与“类似他者”客源市场之间友好且独特的关系, 以提升自身吸引力。目的地还应该唤醒游客积极的集体情感和怀旧, 产生主客情感共鸣, 并避免负面情绪, 以尽力提升来自“类似他者”客源地的游客的体验。

Este estudio pretende contribuir a la teoría de la identidad social en turismo mediante la exploración de las reflexiones de los turistas chinos que visitan Corea del Norte y cómo negocian su identidad intergrupal en este destino similar a otros.

Los datos se recogieron mediante plataformas en línea y entrevistas en profundidad. Se utilizó un enfoque cualitativo a través de análisis temático para analizar los dos conjuntos de datos.

Los resultados mostraron que, al encontrarse con norcoreanos percibidos como otros similares en el entorno social, económico y político en el que estaban integrados, los turistas chinos a menudo se categorizaban a sí mismos como turistas ordinarios, turistas con trato preferente y turistas vicarios basándose en las similitudes intergrupales con los norcoreanos. También, realizaban comparaciones intergrupales para aumentar su autoestima a nivel grupal y colectivo, y desarrollaban las estrategias correspondientes para generar distintos compromisos emocionales grupales.

Se presenta un marco teórico en el que se analizan las características de las identidades sociales de los turistas que visitan un destino similar a otro, lo que contribuye a nuestra comprensión de la naturaleza interactiva y contingente de la identidad social en turismo y responde a la necesidad de abordar los contextos sociales más amplios en los que se inserta la identidad de grupo de los turistas.

Se recomienda que los destinos refuercen las relaciones amistosas y únicas con sus mercados emisores similares para mejorar su atractividad. Los destinos deberían esforzarse por mejorar la experiencia de los turistas de sus mercados emisores similares, estimulando su afecto positivo a nivel colectivo, su resonancia emocional y sus recuerdos nostálgicos, y evitando las emociones negativas.
