The purpose of this paper is to address the problem of content immutability and integrity of online scientific periodicals on the sites of small publishers that can be violated not only by the external hack of the publisher’s site but also by publisher’s and author’s misconduct or by submitting different versions of a periodical to different sites.

The authors defined a list of requirements that verify online scientific publications immutability and integrity. Then, the authors analyzed existing projects and recently emerged information on security technologies and identified challenges met during the development and testing. The use of the public blockchain network Ethereum as a secure storage location for data was explained.

The authors developed the method of checking online scientific periodicals for immutability and presented ecosystem architecture to control immutability and integrity of data. On the example of the online periodical “Istoriya”, it was demonstrated how the immutability of online scientific publication has been verified with the use of the public blockchain over a six-month period. First, operating results were evaluated; challenges hampering the implementation of the suggested ecosystem on Ethereum now were identified; and potential advantages of the suggested approach as compared to similar projects were discovered.

The considered prototype is not a ready-to-use system, but in future providing higher transparency and the development of general distributed ecosystem small publishers will have new opportunities for development given that the issues of scalability, reliability and operating speed on a public blockchain will be addressed. Introduction of the described ecosystem may even provoke some changes on such conservative market as that of publishing of academic papers.

This research is one of the first attempts to expand digital object identifier technology with the use of additional verifications based on the data storage and search in the public blockchain. The suggested idea is the example of “blockchainified science” that was brought to implementation in a real online journal. This method has some advantages compared to Crossmark service.

Peer review has been with humans for a long time. Its effective inception dates back to World War II resulting information overload, which imposed a quantitative and qualitative screening of publications. Peer review was beset by a number of accusations and critics largely from the biases and subjective aspects of the process including the secrecy in which the processes became standard. Advent of the Internet in the early 1990s provided a manner to open peer review up to make it more transparent, less iniquitous, and more objective. This chapter investigates whether this openness led to a more objective manner of judging scientific publications. Three sites are examined: Electronic Transactions on Artificial Intelligence (ETAI), Atmospheric Chemistry and Physics (ACP), and Faculty of 1000 (F1000). These sites practice open peer review wherein reviewers and authors and their reviews and rebuttals are available for all to see. The chapter examines the different steps taken to allow reviewers and authors to interact and how this allows for the entire community to participate. This new prepublication reviewing of papers has to some extent, alleviated the biases that were previously preponderant and, furthermore, seems to give positive results and feedback. Although recent, experiences seem to have elicited scientists’ acceptance because openness allows for a more objective and fair judgment of research and scholarship. Yet, it will undoubtedly lead to new questions which are examined in this chapter.

Modelling accurately the transient behaviour of natural convection flow in enclosures been a challenging task because of a variety of numerical errors which have limited achieving the higher order temporal accuracy. A fourth-order accurate finite difference method in both space and time is proposed to overcome these numerical errors and accurately model the transient behaviour of natural convection flow in enclosures using vorticity–streamfunction formulation.

Fourth-order wide stencil formula with appropriate one-sided difference extrapolation technique near the boundary is used for spatial discretisation, and classical fourth-order Runge–Kutta scheme is applied for transient term discretisation. The proposed method is applied on two transient case studies, i.e. convection–diffusion of a Gaussian Pulse and Taylor Vortex flow having analytical solution.

Error magnitude comparison and rate of convergence analysis of the proposed method with these analytical solutions establish fourth-order accuracy and prove the ability of the proposed method to truly capture the transient behaviour of incompressible flow. Also, to test the transient natural convection flow behaviour, the algorithm is tested on differentially heated square cavity at high Rayleigh number in the range of 10³-10⁸, followed by studying the transient periodic behaviour in a differentially heated vertical cavity of aspect ratio 8:1. An excellent comparison is obtained with standard benchmark results.

The developed method is applied on 2D enclosures; however, the present methodology can be extended to 3D enclosures using velocity–vorticity formulations which shall be explored in future.

The proposed methodology to achieve fourth-order accurate transient simulation of natural convection flows is novel, to the best of the authors’ knowledge. Stable fourth-order vorticity boundary conditions are derived for boundary and external boundary regions. The selected case studies for comparison demonstrate not only the fourth-order accuracy but also the considerable reduction in error magnitude by increasing the temporal accuracy. Also, this study provides novel benchmark results at five different locations within the differentially heated vertical cavity of aspect ratio 8:1 for future comparison studies.

Considering the relevance of understanding what influences environmentally sustainable consumer choices, the present study aims to examine and synthesize the key determinants factors from literature and outline a new conceptual framework for explaining green purchasing behaviors (GPBs).

A bibliometric analysis was conducted on 161 articles extracted from Web of Science and Scopus databases, which were systematically evaluated and reviewed, and represent the current GPB knowledge base. Content analysis, science mapping and bibliometric analysis techniques were applied to uncover the major theories and constructs from the state-of-the-art.

The evolving debate between altruistic and self-interest consumer motivations reveals challenges for rational-based theories, as most empirical applications are not focused on buying behaviors, but instead either on pro-environmental (non-buying) activities or on buying intentions. From the subset of leading contributions and emerging topics, nine thematic clusters are unveiled in this investigation, which were combined to create the new PSICHE framework with the purpose of predicting GPB: (P)roduct-related factors, (S)ocial influences, (I)ndividual factors, (C)oncerns about the environment, (H)abits and (E)motions.

By uncovering the multiple intervening factors in GPB decision processes, this study will assist practitioners and academics to move forward on how to foster more sustainable consumer behaviors.

The present study provides readers a summary of an unprecedentedly broad collection of papers, from which the key themes are categorized, the domain's intellectual structure is captured and an actionable framework for enhancing the understanding GPB is proposed. Four new thrust areas and a set of future research questions are included.

The purpose of this study is to explore the literature of healthcare service quality for identifying and analyzing the healthcare service quality models and dimensions and to present future research insights pertaining to the applications of these models and dimensions.

A literature review of healthcare service quality has been performed on 59 relevant studies after applying inclusion and exclusion criteria. Google Scholar and Scopus are the primary sources to find the relevant documents. Search was limited to keywords of “service quality,” “healthcare,” “models” and “dimensions.”

The results revealed that different models and dimensions have been evolved and developed after SERVQUAL in healthcare service quality literature. There is still a need to develop new models, add new contextual dimensions and items in existing models on different aspects of healthcare services. There is also a need to incorporate the perspective of service providers as respondents. Moreover, healthcare service quality models can be devolved or narrowed down at department and individual levels.

This study presents valuable research insights for the researchers and practitioners in ways that healthcare service quality models and dimensions can be developed, modified and tested further in different research contexts and settings. Besides, the literature on healthcare services can be enhanced and enriched.

The purpose of this study is, first, to understand if the firms are displaying integrated approach toward electronic waste management and sustainability and, second, is there a business case for linking e-waste management with sustainable development goals (SDGs) pronounced by the United Nations.

This study conducts an extensive literature review to gather perspective from multiple disciplines and also carries out content analysis of annual reports/sustainability reports of the firms.

Bulk consumers have sustainability policies and/or strategies but many of these firms have not linked their e-waste management with their sustainability strategies practices. Also, based on the elaboration of different perspectives, this study provides an integrative framework that suggests focus of a particular perspective on a given SDG and commensurate business approach by the firms to find a synergy between the two.

This study provides a wider perspective on the subject of electronic waste management and its linkage with SDGs to create business case, thus opening up many theoretical avenues.

The policy like extended producers’ responsibility has a clear practical implication in terms of creating reputational capital for the firms by linking electronic waste management and SDGs.

The SDG, detailing clean water and sanitation by asking firms not to pollute water bodies by dumping the waste, has clear social implications.

This study is first of its kind to explore the linkage between electronic waste and SDGs to understand the business case. It also throws good insights on whether the firms use integrated approach toward electronic waste management and sustainability.

Membrane biological reactor (MBR) is recognized as an efficient and steady wastewater treatment process. The purpose of this study is to reveal the research trends of scientific outputs on MBR for the past 32 years.

A method of bibliometric analysis was performed, based on the online version of the Science Citation Index Expanded, Web of Science, from 1982 to 2013. In total, 5,305 articles related to MBR were evaluated. A new method named “word cluster analysis” was also used for further analysis.

Results showed a rising trend of publications in this research field. English was the main language used in these articles. Journal of membrane science published the most articles, proving to be one of the most authoritative journals. China and Dalian University of Technology were the most productive country and institute, respectively. Except for “membrane bioreactor” and “MBR”, “membrane fouling” was the most cited keyword, indicating the research hotspot nowadays and future.

This study serves as an alternative and innovative way of revealing the research trends in MBR research.
