This work aims to concentrate on the mixed convection of the stagnation point flow of ternary hybrid nanofluids towards vertical Riga plate. Aluminum trioxide (Al₂O₃), silicon dioxide (SiO₂) and titanium dioxide (TiO₂) are regarded as nanoparticles, with water serving as the base fluid. The mathematical model incorporates momentum boundary layer and energy equations. The Grinberg term for the viscous dissipation and the wall parallel Lorentz force coming from the Riga plate are taken into consideration in the context of the energy equation.

Through the use of appropriate nonsimilar transformations, the governing system is transformed into nonlinear nondimensional partial differential equations (PDEs). The numerical method bvp4c (built-in package for MATLAB) is used in this study to simulate governing equations using the local non-similarity (LNS) approach up to the second truncation level.

Numerous graphs and numerical tables expound on the physical properties of the nanofluid temperature and velocity profiles. The local Nusselt correlations and the drag coefficient for pertinent parameters have been computed in tabular form. Additionally, the temperature profile drops while the velocity profile increases when the mixed convection parameter is included to oppose the flow.

The fundamental goal of this work is to comprehend how ternary nanofluids move towards a vertical Riga plate in a mixed convective domain with stagnation point flow.

This study investigates the flow and heat transfer in a magnetohydrodynamic (MHD) ternary hybrid nanofluid (HNF), considering the effects of viscous dissipation and radiation.

The transport equations are transformed into nondimensional partial differential equations. The local nonsimilarity (LNS) technique is implemented to truncate nonsimilar dimensionless system. The LNS truncated equation can be treated as ordinary differential equations. The numerical results of the equation are accomplished through the implementation of the bvp4c solver, which leverages the fourth-order three-stage Lobatto IIIa formula as a finite difference scheme.

The findings of a comparative investigation carried out under diverse physical limitations demonstrate that ternary HNFs exhibit remarkably elevated thermal efficiency in contrast to conventional nanofluids.

The LNS approach (Mahesh et al., 2023; Khan et al., 20223; Farooq et al., 2023) that we have proposed is not currently being used to clarify the dynamical issue of HNF via porous media. The LNS method, in conjunction with the bvp4c up to its second truncation level, yields numerical solutions to nonlinear-coupled PDEs. Relevant results of the topic at hand, obtained by adjusting the appropriate parameters, are explained and shown visually via tables and diagrams.

The purpose of this study is to explain the components of competitive priorities of Indian service firms, to find out the competitive priorities of different service industries in India and to find out how these competitive priorities change across low- and high-performing service firms.

An empirical study of 166 firms from five different service industries is undertaken in New Delhi and its surroundings.

The results reveal the presence of three competitive priorities in the services sector in India: cost, flexibility and quality/delivery, with quality/delivery being the most distinctive competitive priority. Hotel and auto-repair industries are found to be focused on controlling costs, while hospitals, banks and private colleges prioritized quality/delivery. For high-performing firms, cost is the top most competitive priority, followed by quality/delivery and flexibility, while for low-performing firms, quality/delivery remains the top most competitive priority, followed by flexibility and cost.

The paper enhances the understanding of competitive priorities in the Indian services sector. The identification of competitive priorities of different service industries in India and their dynamics across different industries add value to the current literature and fill an important research gap. Additionally, surveying diverse industries in this paper reveals a holistic picture of the Indian service industry and helps achieve some degree of cross-industry perspective.

Supervisor phubbing is an increasingly common behavior depicted by supervisors despite the significance of supervisor–subordinate interactions. This study explores the impact of this behavior on workplace incivility and workplace presenteeism and analyzes the mediating role of self-esteem and the moderating role of power distance.

Data were collected from employees belonging to IT sector. The research was cross-sectional in nature and the data were collected using a structured questionnaire.

The findings indicate a significant impact of supervisor phubbing on self-esteem, workplace incivility and workplace presenteeism. Additionally, results reveal the mediating role of self-esteem between supervisor phubbing and workplace presenteeism. However, the moderating effect of power distance on the relationship between supervisor phubbing and self-esteem was not supported.

The research contributes to the existing literature and theory, especially in the area of supervisor phubbing and communications management. The study suggests a need for comprehensive approach that involves both organizational policies and individual behavior change.

The purpose of this paper is to analyze the e-resource collection development practices of the engineering college libraries of Aligarh. The research includes budgeting, collection development policy, collection evaluation, sources of funds, modes of procurement, pricing models and other aspects related to collection development activity.

The descriptive method was used for conducting the study, in which a well-structured questionnaire was administered followed by interview of the librarians of six engineering college libraries under study.

It was found that these colleges are much more interested in focusing on building a strong e-resource collection in their libraries. During the past few years, the budget has also been increased in majority of libraries for the acquisition of e-resources. The study found that the major factors affecting the selection of electronic resources (e-resources) in these colleges are quality, subject coverage, license agreement and vendor support. It was also revealed that majority of libraries lack proper collection development policy, especially for e-resources. The study suggested that these libraries should build their collections keeping in mind the different areas of specializations of engineering studies and the contemporary changes in the field.

The paper is restricted exclusively to the study of collection development process of e-resources and the librarians of six major engineering colleges of Aligarh as respondents.

This study has great importance for the librarians of the similar engineering colleges in India. The findings and suggestions of the study can help not only in understanding the engineering college librarianship and its current trends but can also help library professionals who are facing similar challenges in their libraries.

The present study is about the e-resource collection development practices followed in engineering colleges of Aligarh, which can serve as a pedestal for future studies in other academic and special libraries in India and elsewhere.

This study aims to examine the role of organisational commitment (affective, normative, continuance) in influencing employees’ knowledge application behaviour during the COVID-19 pandemic. This study also probes the moderating role of leader–member exchange (LMX) in the association between organisational commitment and knowledge application.

This study used a sample of 206 employees working in various private sector organisations in Brunei Darussalam. Structural equation modelling using Smart-PLS was used to test the hypothesised relationships.

The findings show that affective and normative organisational commitment spurred employees’ knowledge application behaviour significantly during the COVID-19 crisis. However, the moderating effect of LMX could not be established in this study.

The findings provide managers with insights into the crucial role organisational commitment can play in encouraging knowledge application in an organisation.

Studies exploring the enabling factors of knowledge application are scarce, especially in the context of a global crisis such as the COVID-19 pandemic. This study develops a model and empirically validates the importance of organisational commitment for knowledge application amidst the COVID-19 pandemic. This study also provides insights for managers into how LMX can affect knowledge application outcomes, particularly during uncertain times.

This paper aims to synthesize and critically explore the available knowledge about the linkages between compulsory citizenship behavior, knowledge hiding and employee innovative performance through a systematic literature review. It proposes a conceptual framework, highlighting the core relationships between these constructs.

Using two databases (Dimensions and Scopus), the authors critically examine 93 peer-reviewed publications from 2006 to 2023 to identify the arguments supporting the associations between the studied constructs.

Through an integrative conceptual model, this study provides insights into the devastating impact of compulsory citizenship behavior on employee innovation performance, further suggesting how knowledge hiding may play a mediating role.

The study's main limitation lies in its conceptual nature. Future research should empirically validate the model to gain richer perspectives into the linkages.

The existing body of literature lacks a comprehensive understanding of the nexus between compulsory citizenship behavior, knowledge hiding and employee innovative performance. This study is a pioneer since it explores the emerging concepts of compulsory citizenship behavior and knowledge hiding and accentuates their presence in the context of innovative performance at the individual level through coercive persuasion theory and cognitive dissonance theory.

Grounded in the Social Exchange theory, this study focuses on the perception of digital leadership and innovative work behaviors. It also examines the complex effects of leader-member exchange, learning orientation, and innovation capabilities.

We undertake a quantitative approach using a two-wave longitudinal field survey of 440 employees and managers from various backgrounds working in the automobile industry in France.

The findings based on Structural Equation Modeling reveal that the perception of digital leadership leads to innovative work behavior while leader-member exchange moderates between the perception of digital leadership and learning orientation. The findings also support the mediating roles of learning orientation and innovation capabilities.

The study contributes important policy suggestions, raises queries for additional investigation, and suggests theoretical and practical implications for leadership and organizational environmental factors to foster innovative work behaviors in organizations.

This study attempts to explain the components of competitive priorities of Malaysian service firms and to find out the competitive priorities of different service industries in Malaysia, and how these competitive priorities change across “low performance” and “high performance” service industries.

An empirical study of 254 firms from nine different service industries is conducted to answer the objectives of this study.

Four competitive priorities are identified: cost, quality, delivery and flexibility. Six service industries namely fast food, hospital, retail store, bank, private college and accountant industries are found to be focused on quality while three industries namely hotel, auto‐repair and architect prioritized delivery. For both high performance and low performance firms, quality remained the top competitive priority followed by delivery, flexibility and cost.

This is the first study that identifies competitive priorities in the Malaysian service sector

Industry and academia are interested to understand how companies develop alliance capabilities through managing the knowledge, for alliance success. This study aims to investigate how alliance learning process is related to the overall success of any alliance, and how openness culture moderates the relationship of alliance learning process and alliance success.

English language questionnaires were sent to top executives of 400 companies because English is a commonly understood language at managerial level in Pakistani companies. In total, 186 usable answers were received. Hierarchical linear regression was used for hypothesis testing.

Alliance learning is significantly and positively related to alliance success. Openness plays a role as moderator between the relationship of alliance learning process and alliance success. Contrary to the literature, at low level of alliance learning, high level of openness increases the chances of alliance but as we move toward high level of alliance leaning, low level of openness is more effective to achieve the alliance success.

The data in this study was collected from Pakistan. The results may not be generalized to other regions, especially to developed countries.

The results have implications for managers involved in alliances. They can be benefitted by this study to understand the role of alliance (knowledge) learning process on alliance success and contingent role of openness on this relationship.

This study is an important contribution to understand the notion of organizational learning and knowledge management in alliance context. To the best of the authors’ knowledge, this is the first study to investigate openness as a moderator of the relationship between alliance learning process and alliance success.
