This study aims to explore how and when negative workplace gossip damages hospitality employees’ career growth, based on social information processing (SIP) and social cognitive career theories.

The authors gathered data from 379 individuals working in Guangzhou’s hospitality industry with a multi-wave survey.

This research found that negative workplace gossip harms career growth by damaging one’s personal reputation, and concern for reputation plays a moderating role. In particular, employees displaying greater concern for reputation are more inclined to perceive a diminished personal reputation when exposed to negative workplace gossip, resulting in more negative assessments of their career growth prospects in their organization.

This study has some practical implications. It highlights the need to mitigate negative workplace gossip by fostering a harmonious work environment, implementing reputation-focused training programs and providing support to employees who are particularly concerned about their personal reputations.

This research contributes to the knowledge by empirically revealing the career consequences of negative workplace gossip, incorporating personal reputation and concern for reputation in the theoretical model and advancing research in the vocational and gossip domains. It also enriches SIP and social cognitive career theories while focusing on the hospitality industry.

The purpose of this paper is to present a practical method for computing contingency‐based reliability and quality indices in power systems and to answer questions related to how much the system is reliable, how robust it is in surviving random contingencies, how much it is costing to maintain appropriate system security and reliability levels and, finally, to what extent the desired balance is maintained between generation facilities, transmission capabilities and consumer demand levels in various zones of the electric power system.

The methodology adopted in this paper is based on a combined contingency analysis/reliability evaluation scheme. A three‐component system model is utilized, which can be used effectively for evaluation and sensitivity analysis of reliability and quality in power systems. The model is a reduced (equivalent) system representation that comprises generation, transmission and load components with multi‐state values. The computational scheme presented in the paper integrates both the contingency effect and its probability of occurrence into one routine of analysis while reducing the power system around the region of interest.

The computational scheme presented in the paper can effectively assess both service reliability and system quality. The practical applications presented demonstrated that lower service reliability levels would jeopardize energy supply continuity and increase the likelihood of additional maintenance and restoration costs due to the resulting higher rate of system outages. Poor system quality levels, on the other hand, imply either deficiency or excess in the overall system capabilities as designed by its planners.

The work of this paper contributes to the solution of the reliability and quality assessment problem in practical power systems. As part of the present work, an advanced computerized scheme for fast composite system reliability and quality assessment was developed and then applied to an equivalent system model of the Saudi electricity system. The results obtained are claimed to have far‐reaching implications on various planning and operation aspects of the power system.

Research on informal social networks is gaining momentum. However, there is still much we do not know about these networks and how they impact business practices in the countries in which they operate. This chapter presents the authors' perspectives on the current state of wasta (as a case study of informal social networks) research and the future directions that need to be explored in relation to wasta to further unpack this practice and to capture its complexity in a way that allows both researchers and practitioners to manage it. It is observed that wasta research is currently too reliant on short timeframe case studies which are mostly qualitative. While these have improved in their theoretical, practical and methodological rigor, it is suggested that there is a need for more mixed methods longitudinal and statistical modeling research. We conclude this chapter by suggesting ways in which wasta researchers can “borrow” from other disciplines to enhance our understanding of this practice.

This study aims to investigate how indigenous socio-cultural (ISC) practices within informal networks, such as guanxi and wasta, provide benefits beyond mere access. Specifically, the authors explore their global impact on B2B relationships, focusing on reciprocity. A multiregional sample extends research on ISC practices in B2B relationships by examining contingency effects of informal network ties.

The authors surveyed 404 buyers in two developed (Hong Kong and Portugal) and two emerging economies (Kuwait and Colombia), and also categorized by strong and weak informal network ties. Using structural equation modeling, the authors examined a relationship marketing (RM) model from a typology (Clubs, Sociocracies, Clans and Compadres) for assessing contingency effects.

The study reveals that in developed economies with strong formal institutions, negative aspects of favor reciprocity norms intensify unless informal networks are driven by strict sociomoral obligations. This supports research indicating that contractual governance competes rather than complements relational governance. Moreover, trust-building processes are crucial in regions with low uncertainty tolerance to mitigate adverse effects.

Suppliers from developed nations need more than cultural communication insights when engaging in business in emerging markets. We acknowledge changes buyers may expect adherence to reciprocity rules embedded in the ISC practices of their informal networks.

This study pioneers a typology of social structures to analyze ISC practices across buyers with varying formal institutional strength and informal network ties. It sheds light on institutional dynamics, trust-building processes, and nuances surrounding both positive and negative aspects of reciprocity practices. Furthermore, it broadens the scope of RM to Asia, Europe, Latin America and the Middle East.

This systematic review aims to assess the studies collected by identifying factors influencing the acceptance of e-learning systems before and during the current propagation of the COVID-19 pandemic.

This study undertook a literature review on the in-depth revision of studies published before 2021. The reviewed research papers meet the inclusion and exclusion criteria. A total of 97 out of 214 articles met the inclusion criteria and were subsequently used in this review.

The findings revealed that the survey questionnaire is the most common data collection instrument used regardless of the research objectives. 2019 was a remarkable year because of the emergence of the COVID-19 pandemic.

This systematic review relied on specific databases (ScienceDirect, Emerald, IEEE and Google Scholar) to search for the articles included in this paper. However, these databases may not comprehensively represent all papers published on e-learning using the technology acceptance model (TAM).

This paper suggests a guide for managers and scholars in educational institutions and acts as a roadmap for practitioners and academics in the educational field and policymakers. This research spotlights the significant factors influencing the acceptance and adoption of e-learning.

This research assessed articles that examined the TAM in e-learning and classified them according to their methodology, country of dissemination, context and distribution within the year of publication. This paper contributes to the body of knowledge in a way that will benefit stakeholders in an educational setting.

Buildings are responsible for the consumption of around 40% of energy in the world and account for one-third of greenhouses gas emissions. In Saudi Arabia, residential buildings consume half of total energy among other building sectors. This study aims to explore the impact of sixteen envelope variables on the operational and embodied carbon of a typical Saudi house with over 20 years of operation.

A simulation approach has been adopted to examine the effects of envelope variables including external wall type, roof type, glazing type, window to wall ratio (WWR) and shading device. To model the building and define the envelope materials and quantify the annual energy consumption, DesignBuilder software was used. Following modelling, operational carbon was calculated. A “cradle-to-gate” approach was adopted to assess embodied carbon during the production of materials for the envelope variables based on the Inventory of Carbon Energy database.

The results showed that operational carbon represented 90% of total life cycle carbon, whilst embodied carbon accounted for 10%. The sensitivity analysis revealed that 25% WWR contributes to a significant increase in operational carbon by 47.4%. Additionally, the efficient block wall with marble has a major embodiment of carbon greater than the base case by 10.7%.

This study is a contribution to the field of calculating the embodied and operational carbon emissions of a residential unit. Besides, it provides an examination of the impact of each envelope variable on both embodied and operational carbon. This study is limited by the impact of sixteen envelope variables on the embodied as well as operational carbon.

This study is the first attempt on investigating the effects of envelop variables on carbon footprint for residential buildings in Saudi Arabia.

Based on the Sociometer Theory, this study aims to develop a comprehensive framework explaining how and when negative workplace gossip triggers distinct responses, including employee silence and compulsory citizenship behavior (CCB).

Two scenario-based experiments and a field survey were conducted to examine hypotheses. Study 1 (N = 149) manipulated workplace negative gossip and assessed the mediating effects of state self-esteem. Study 2 (N = 217) manipulated workplace negative gossip and consideration of future consequences (CFC) to verify the stability of the mediating mechanism and test the moderating effect of CFC. Study 3 (N = 321) tested the whole research model.

The findings indicate that negative workplace gossip decreases state self-esteem, resulting in silence among employees with low levels of CFC, while inducing CCB through state self-esteem among employees with high levels of CFC.

This study not only extends the research of negative workplace gossip by exploring its multifaceted impact on employee responses but also highlights the role of personality traits in shaping individuals’ response strategies.

This study aims to investigate factors that could predict the continued usage of e-learning systems, such as the learning management systems (LMS) at a Technical University in Ghana using machine learning algorithms.

The proposed model for this study adopted a unified theory of acceptance and use of technology as a base model and incorporated the following constructs: availability of resources (AR), computer self-efficacy (CSE), perceived enjoyment (PE) and continuance intention to use (CIU). The study used an online questionnaire to collect data from 280 students of a Technical University in Ghana. The partial least square-structural equation model (PLS-SEM) method was used to determine the measurement model’s reliability and validity. Machine learning algorithms were used to determine the relationships among the constructs in the proposed research model.

The findings from the study confirmed that AR, CSE, PE, performance expectancy, effort expectancy and social influence predicted students’ continuance intention to use the LMS. In addition, CIU and facilitating conditions predicted the continuance use of the LMS.

The use of machine learning algorithms in e-learning systems literature has been rarely used. Thus, this study contributes to the literature on the continuance use of e-learning systems using machine learning algorithms. Furthermore, this study contributes to the literature on the continuance use of e-learning systems in developing countries, especially in a Ghanaian higher education context.

Digitalisation is reshaping the learning process, shifting it towards personalisation and online learning, and fuelling the growth of massive open online courses (MOOCs) and micro-credentials. Despite being a popular global trend, limited studies have looked at micro-credentials and their impact on learners' behavioural outcomes. The purpose of this study is to investigate the impact of programme design factors on learning experience, as well as the inter-relationships between programme design, learning experience and behavioural responses (e.g. engagement and willingness to pay more (WTPM)) towards micro-credentials. In addition, the study aims to investigate learning enjoyment as a moderator.

A survey questionnaire was used to collect data from 354 respondents who are working adults living in the major economic states in Malaysia. Data analysis was performed using the analysis of a moment structures (AMOS) statistical software and SPSS (Statistical Package for the Social Sciences) PROCESS macro.

The results show the significance of programme design factors (i.e., flexibility, system quality and content quality) in determining the learning experience. The learning experience is found as a mediator in the relationship between programme design factors and learner engagement and WTPM. In addition, the moderation assessment confirms that enjoyment during learning strengthens the relationship between experience and behavioural responses.

This study is amongst a few selected studies that focus on engagement in and WTPM for micro-credentials. In addition, it emphasises the mediating role of the learning experience and the moderating role of enjoyment in understanding the impact of programme design on learners' experiences and behavioural responses.

Drawing upon compensatory ethics theory, this study explored the underlying mechanisms through which gossipers engaged in helping behavior as a form of compensation after initiating negative workplace gossip.

Through a two-wave field study of 394 Chinese employees, this study tests theoretical hypotheses using path analysis and bootstrapping methods.

The findings suggested that negative workplace gossip positively influenced the gossipers’ helping behavior through moral self-image and guilt. Moreover, moral reflectiveness not only positively moderated the impacts of negative workplace gossip on moral self-image and guilt but also positively moderated the mediating effects of moral self-image and guilt in the relationship between negative workplace gossip and helping behavior.

These results enrich the theoretical research on negative workplace gossip, offer new perspectives for studying this phenomenon and provide a theoretical basis and decision-making reference for management practices.
