Abstract

Purpose

The model incorporates key factors of membrane such as permeability and resistance, feed concentration, fluid viscosity and pressure differentials. Special emphasis is placed on the fouling mechanisms, including pore blockage and cake layer formation, which significantly impact the efficiency of the filtration process.

Design/methodology/approach

In this study, we present a numerical analysis of permeate flux through a membrane, focusing on the intricate dynamics of fouling phenomena. Utilizing the Langevin model, we simulate the permeation process to understand how various operational parameters affect the flux rates.

Findings

Our results demonstrate that fouling not only reduces the permeate flux but also alters the membrane’s hydraulic resistance over time. The results show that the increasing of the diffusion process on membrane reduces the clogging phenomenon. Hence, the increases of the transmembrane pressure reduce exponentially blocking pore process.

Originality/value

By analyzing these changes, we provide insights into optimizing membrane performance and developing strategies to mitigate clogging membrane. This research contributes to the field of membrane technology by enhancing our understanding of permeate flux behavior under fouling conditions and offering potential pathways for improving long-term operational sustainability.

Abstract

Purpose

This paper aims to analyze brand loyalty and electronic word-of-mouth (eWOM) antecedents in restaurants: (1) utilitarian and hedonic benefits, (2) brand satisfaction and (3) brand love. It also provides valuable knowledge through the comparison between positive and negative restaurant experiences.

Design/methodology/approach

A survey was carried out of restaurant satisfied and dissatisfied consumers. Structural equation modeling (SEM) and multi-group analysis (MGA) were performed to examine the cause-and-effect relationship in both groups.

Findings

The results show the relevance of benefits, brand satisfaction and brand love as causes for brand loyalty and e-WOM. Also, these relationships are significantly stronger for dissatisfied consumers than for satisfied ones.

Originality/value

The outcome of the research provides new insights to develop a conceptual stimulus-organism-response (S-O-R) model of consumers’ restaurant behavior by drawing comparisons across satisfied and dissatisfied ones.

Abstract

Purpose

This paper examines how the Camburi Quilombo community in Ubatuba, Brazil, can be empowered to develop cultural resilience and conserve its Afro-Brazilian heritage in the face of challenges posed by climate change, urbanization and cultural erosion with the adverse consequences of tourism and inadequate infrastructure.

Design/methodology/approach

Emphasizing traditional knowledge, the project consisted of data collection, climate risk assessments and the development of an action plan in collaboration with academic institutions, governmental bodies and nongovernmental organizations (NGOs).

Findings

Aligned with sustainable development goals (SDGs), the project contributes to zero hunger, quality education, sustainable cities, climate action and life on land. Seed exchange fairs, decentralized seed banks and education initiatives foster environmental awareness and sustainable agriculture, impacting the community directly and over 1,000 individuals indirectly. While demonstrating short-term changes and mid-term viability, the project faced some challenges due to local communication complexities and overlapping jurisdiction.

Originality/value

Serving as a bridge between scientific research and local knowledge, the project aims to promote a paradigm shifts toward recognizing, respecting and incorporating indigenous practices, so that a more environmentally aware future can be envisioned for these communities amidst climate challenges. Reflecting on achievements, the project underscores integrating diverse cultural knowledge for community resilience.

Abstract

Purpose

This study aims to advance knowledge of channel integration, a key feature of omnichannel retailing, by investigating the role of specific touchpoints in delivering a consistent integration perception.

Design/methodology/approach

Quantitative methods were adopted, by testing a model built on the stimulus-organism-response framework. Data collection used a panel survey across the grocery and fashion sectors (1,031 and 739 consumers, respectively). An ordinary least squares regression with clustered standard errors was conducted, combined with a multiple correspondence analysis, followed by a mediation analysis.

Findings

This study identifies touchpoints relevant for channel integration perception and shows that they differ across product category and customer types (first time vs repeat customers). Furthermore, it pinpoints touchpoints that are directly and indirectly related to patronage intention, thereby exposing the mediating role of channel integration. By drawing on categorization theory, it discusses individual touchpoints’ contribution to channel integration perception, at general level and on different customer targets.

Practical implications

This study offers a new vision of channel integration perception that highlights touchpoints’ role. It contributes to the established channel integration quality framework by showing that integrated information is concerned not only with consistency of information across channels but also with the specific touchpoints through which such information is disseminated.

Originality/value

This study provides directly actionable managerial implications, by through strategic insights for customer journey and customer experience design/redesign and by offering a practical methodology for retailers to identify the touchpoints they can leverage to improve their customers’ channel integration perceptions – with consequences for patronage intention.

Abstract

Purpose

This paper aims to contextualize the process of public hospital providing services, based on the measurement of the performance of Federal University Hospitals (HUFs) of Brazil, using the technique of multivariate statistics of principal component analysis.

Design/methodology/approach

This research presented a descriptive and quantitative character, as well as exploratory purpose and followed the inductive logic, being empirically structured in two stages, that is, the application of principal component analysis (PCA) in four healthcare performance dimensions; subsequently, the full reapplication of principal component analysis in the most highly correlated variables, in module, with the first three main components (PC1, PC2 and PC3).

Findings

From the principal component analysis, considering mainly the component I, with twice the explanatory power of the second (PC2) and third components (PC3), it was possible to evidence the efficient or inefficient behavior of the HUFs evaluated, through the production of medical residency, by specialty area. Finally, it was observed the formation of two groups composed of seven and eight hospitals, that is, Groups II and IV, which shows that these groups reflect similarities, with respect to the scores and importance of the variables for both hospitals’ groups.

Research limitations/implications

Among the main limitations, it was observed incomplete data for some HUFs, which made it impossible to search for information to explain and better contextualize certain aspects. More specifically, a limited number of hospitals with complete information was dealt with for 60% of SIMEC/REHUF performance indicators.

Practical implications

The use of PCA multivariate technique was of great contribution to the contextualization of the performance and productivity of homogeneous and autonomous units, represented by the hospitals. It was possible to generate a high quantity of information, to contribute with assumptions to complement the decision-making processes in these organizations.

Social implications

Development of public policies, with emphasis on hospitals linked to teaching centers represented by university hospitals. The projection of improvements in the reach of the efficiency of the services of assistance to the public health, from the qualified formation of professionals, both to academy, as to clinical practice.

Originality/value

The originality of this paper for the scenarios, Brazilian public health sector and academic area involved the application of a consolidated performance analysis technique, that is, PCA, obtaining a rich work in relation to the extensive exploitation of techniques to support decision-making processes. In addition, the sequence and the way in which the content, formed by object of study and techniques, has been organized, generating a particular scenario for the measurement of performance in hospital organizations.

This study aims to propose and apply a sustainability assessment model (SAM) for the mineral extraction industry developed on the basis of elements of dialogic accounting.

Abstract

Purpose

This study aims to propose and apply a sustainability assessment model (SAM) for the mineral extraction industry developed on the basis of elements of dialogic accounting.

Design/methodology/approach

Distinct from other similar exercises, ours is also one in external accounting that focuses on a set of mining companies operating in a specific geographical location. It was undertaken based on different perspectives from various stakeholders, including mining workers and city dwellers, retrospectively, using publicly available information, entirely independently of the set of companies regarding which impacts the authors try to offer an account and without their approval. Twenty indicators were identified from the perspective of value for society.

Findings

The results for all environmental externalities appeared to be negative, as companies’ attitudes continue to be reactive and on the threshold of legal requirements. This assessment of the selected social indicators emphasizes that accelerated expansion of mining activities poses a threat to the mining area in the long term, as it reduces the useful lives of mineral deposits and expands social and environmental externalities.

Practical implications

The authors propose to expand the horizon of accounting through a framework that combines elements of the SAM technology, dialogic accounting and external accounting. This investigation contributes to the development of social and environmental accounting practices through the discussion, proposal and use of an SAM, built with the cooperation of several social actors and from the perspective of the other rather than the entity.

Social implications

The authors tried to show how an SAM approach can be used in combination with dialogic accounting processes, increasing the accountability and awareness of the different groups of stakeholders, focusing on marginalized stakeholders, to offer an external account of the impacts of a set of companies from the mining sector operating in a specific geographical area.

Originality/value

This study’s findings suggest there are opportunities for accountants to support social and environmental accounting, thereby contributing to community awareness and empowering transformative action.

The purpose of this study is to examine whether there are differences in second-hand online shopping behavior driven by the generational cohort.

Abstract

Purpose

The purpose of this study is to examine whether there are differences in second-hand online shopping behavior driven by the generational cohort.

Design/methodology/approach

Based on the generational cohort theory, this research examines what factors influence and prevent the purchase of second-hand products online, comparing generational cohorts. For this purpose, data are analyzed through multiple-group structural equation modeling (SEM) (Gen X = 176; Millennials = 197; Gen Z = 233).

Findings

Findings report noticeable different motivations and barriers across consumer generations in their second-hand shopping behavior: Gen X are mostly driven by economic motivations; Gen Z are driven by ethical motives, while economic and environmental motivations exert greater influence for Millennials. Conversely, functional risk is the main barrier for the three generational cohorts.

Originality/value

To the best of the authors’ knowledge, this is one first attempt to examine why different generational cohorts of consumers purchase or prevent from purchasing used items through the internet.

Abstract

Purpose

This paper aims to identify potential barriers to Industry 4.0 adoption for manufacturers and examine the changes that must be made to production processes to implement Industry 4.0 successfully. It aims to develop technology by assisting with the successful implementation of Industry 4.0 in the manufacturing process by using smart system techniques.

Design/methodology/approach

Multiple case studies are used in this paper by using the smart system and Matlab, and semi-structured interviews are used to collect qualitative data.

Findings

Standardization, management support, skills, and costs have been cited as challenges for most businesses. Most businesses struggle with data interoperability. Complexity, information security, scalability, and network externalities provide challenges for some businesses. Environmental concerns are less likely to affect businesses with higher degrees of maturity. Additionally, it enables the Technical Director’s expertise to participate in the measurement using ambiguous input and output using language phrases. The outcomes of the numerous tests conducted on the approaches are extensively studied in the provided method.

Originality/value

In this research, a multiple-case study aims to carry out a thorough investigation of the issue in its actual setting.

Abstract

Purpose

The empirical study of factors related to digital transformation (DT) in the banking sector is still limited, even though the importance of the topic is universally evident. To bridge that gap, this paper aims to explore the role of digital leadership (DL), innovative culture (IC) and technostress inhibitors (TI) to support engagement for improved digital innovation (DI). Based on the literature, these variables are crucial aspects of digitalisation, even though there is no agreement on their conclusiveness.

Design/methodology/approach

This quantitative study tested a new conceptual model using survey data from five major banks in Libya. Partial least squares structural equation modelling was used to analyse the data from the 292 usable responses.

Findings

The results showed that DL and IC positively affect DI. Techno-work engagement (TE) mediated the relationship between leadership, culture and innovation. TI played a significant moderating role in leadership, culture and engagement relationships.

Practical implications

The research findings highlight critical issues about how leadership style and fostering organisational support in the banking sector can enhance DT. Leaders must demonstrate a commitment to long-term resource allocation to avoid possible negative effects from digital stress while pursuing DI through work engagement.

Social implications

The study suggests that fostering organisational support can enhance DT in retail banks, potentially leading to improved customer experiences and increased access to financial services. These programs will help banks contribute to societal and economic development.

Originality/value

This timely study examines predictor mechanisms of innovation in retail banking that resonate within the restrictions of organisational and DI frameworks and the social exchange theory. Exploring the intervening effect of TE in the leadership, culture and innovation associations is unprecedented.
