Purpose The purpose of this paper is to propose a set of constitutive functions for dried bodies for accurate prediction of the entire deformation process of ceramic products during firing and to present relevant methods for determining their coefficients from a series of respective thermo-mechanical analysis (TMA) tests. Design/methodology/approach The function forms of the sintering-induced strain rate, viscoplastic multiplier and elastic modulus are formulated in order with reference to empirical data of relative densities. Separate TMA tests are conducted to identify their coefficients, while a stairway thermal cycle test is carried out to identify the parameters in the densification rate. Then, various finite element analyses (FEA) are performed for accuracy confirmation. Findings The performances of the present constitutive functions along with the identified material parameters were validated in comparison with the relevant test results. It has then been confirmed that these functions enable us to some extent to accurately estimate the non-mechanical and mechanical deformations of dried bodies during firing. Also, by performing FEA of an actual sanitary ware product, the applicability and capability of the proposed set of constitutive functions could be demonstrated. Practical implications The present methodology with the proposed constitutive functions is a simple, but reliable and practical approach for simulating the deformation process of arbitrary ceramic products subjected to firing and applicable for practical applications in various engineering fields. Originality/value The constitutive functions of the viscoplastic multiplier and elastic modulus, which enable us to properly characterize the mechanical behavior of dried bodies subjected to firing, are originally formulated in analogy with that of the sintering-induced strain.

Purpose The purpose of this paper is to elucidate the concept of ḍamān al-milkiyyah (ownership risk) and to assess its application in contemporary Islamic financial products and services. Design/methodology/approach The methodology adopted is that of descriptive research. Findings From an Islamic law of contract perspective, the concept of ḍamān al-milkiyyah is central to legitimate profit-making transactions and hence must be adhered to in practical applications of Islamic finance. Research limitations/implications This study should help motivate further investigation into the position of ḍamān al-milkiyyah among different parties in existing Islamic financial products and services. Practical implications Policymakers and regulators should ensure that Islamic financial products and services are structured in a way that does not allow parties to profit without adequately bearing the liability for potential loss. Social implications The condition of ḍamān al-milkiyyah as a source of legitimate profit reflects the idea that the role of finance in Islam is to promote and ensure social benefits. Originality/value This paper emphasizes the importance of ḍamān al-milkiyyah as a fundamental condition for profit in Islamic financial transactions.

Purpose The conviction of innocent individuals has emerged as an international concern, resulting in substantial attention to the legal needs that stem from exoneration. However, many other challenges can also arise in the aftermath of an exoneration, including financial, psychosocial and mental health needs. Relatively little has been written about the particular reentry needs of individuals who are exonerated of their charges, and even fewer studies have considered the effectiveness of various treatment approaches. The purpose of this paper is to reviews the available literature, identifies gaps and provides clinical recommendations for the development of treatment interventions for exonerees. Design/methodology/approach The research addressing the needs and challenges that arise in the aftermath of exoneration is reviewed and analysed for implications that can guide treatment-planning in this area. Findings This paper reviews key finds from the literature and provides recommendations for developing a semi-structured approach to treating exonerees. Practical implications Practical applications for the development of effective therapeutic interventions for exonerated individuals are identified and discussed. Originality/value Currently, there is very limited literature addressing the specific reentry needs and effective therapeutic interventions for exonerated individuals.

Purpose Virtual reference is a part of the services offered at academic and other types of libraries. This paper discusses humanistic perspectives that merit consideration in the provision of virtual reference (VR), including mindfulness, authenticity, emotional intelligence (EI) and counseling. This study aims to make these perspectives become a part of the language and practice of virtual reference through this discussion. Design/methodology/approach The paper establishes a framework for the VR perspectives it discusses by examining relevant literature for background information and practical applications. Findings VR has the potential to benefit from the interrelated humanistic perspectives of mindfulness, authenticity, EI and counseling. It is through the counseling perspective that mindfulness, authenticity and EI are embodied to offer a more transformational and less transactional experience for both librarians and users. Research limitations/implications While the paper provides examples of language used by the author to illustrate the counseling perspective, a future study, whereby virtual reference transcripts are formally analyzed, may be beneficial to determine other expressions of counseling and its related perspectives of mindfulness, authenticity and EI. Practical implications This paper provides a resource especially helpful to individuals new to VR or who seek opportunities for growth in providing VR. Originality/value In addition to taking a multifaceted view of VR through the humanistic perspectives presented, this paper also offers a multidisciplinary approach in its discussion, drawing from areas such as business and medicine.

Purpose – The purpose of this paper is to identify key elements of what makes an inventory program effective for cultural heritage conservation and management. It is hoped that it will spur discussion among heritage professionals about increasing the effectiveness of inventory programs. Design/methodology/approach – This paper reflects on more than a decade of experience with the establishment of heritage surveys and inventories at national and citywide scales in the Middle East and North America, and through site-based heritage management projects. In addition, it reflects on engagement with international professionals involved with heritage inventories. Findings – Heritage inventories are permanent, ongoing records that require long-term institutional resource commitments. To be effective for heritage management, inventory programs should be established with links to heritage legislation, built upon data standards, and maintain dedicated personnel, programs of activity, and systems on an ongoing basis. Inventories are fundamentally different than heritage surveys, or other data collection activities, which collect information within a specific timeframe. Practical implications – The findings are based on engagement with real-world, practical applications. It is hoped that the recommendations included will be useful to professionals working in heritage institutions that are establishing inventory programs, or seeking to modernize, invigorate, or increase the effectiveness of their inventory programs. Originality/value – This paper presents insights gained through engagement with a large number and variety of heritage inventory and survey programs and projects from across the world, reflecting on broad trends and patterns.

Purpose The purpose of this paper is to discuss the methodology of integrated knowledge in Islamic economics and finance and seek to offer collective ijtihād as one way to find solutions to the existing problems in the field. Design/methodology/approach The study is based on the idea of multidisciplinarity or interdisciplinarity, which uses not only traditional sources of Islam and economics, such as uṣūl al-fiqh, fiqh mu’amalat, econometrics, statistics, microeconomics and macroeconomics but also looks into behavioural and natural sciences for inspiration and solutions. This paper is constructed using the methodology of “the two readings”, as promoted by the International Institute of Islamic Thought, and which combines the revealed and the existential sciences. Findings This paper proposes the collaborative multidisciplinary methodology as the main approach to studying the modern problems and challenges, as well as for finding solutions in the fields of Islamic economics and finance. Practical implications Studying and researching issues, particularly in the field of Islamic economics and finance, from an interdisciplinary perspective, effectively broadens practical applications and possibilities in Islamic finance. Originality/value This paper contributes to social sciences, especially the field of Islamic finance, and calls upon researchers to engage in multidisciplinary studies.

PurposeThe purpose of this paper is to demonstrate, to construction professionals, the client benefits of archaeological building analysis.Design/methodology/approachThe principles of the technique are summarised, followed by a summary of the academic and legal contexts in which such analyses are conducted. Three short case studies are presented, followed by methodological conclusions.FindingsThe paper finds that after c100 years of methodological development, client interests are not represented in any technical or professional guidance; and that historic buildings are structurally and cosmetically more complex than received architectural histories would have one believe and that much decorative detail is likely to be of relatively recent installation, information that can be of benefit to clients wishing to modify listed and other historic buildings.Research limitations/implicationsWhile the introductions and legal and academic summaries are international in scope, the case studies are limited to its own work. Nonetheless, the principles established are applicable to all forms of historic buildings and refurbishment projects.Practical implicationsThe paper posits that a hitherto regulatory burden can be applied in the clients' interests with only a slight adjustment in approach to well established survey techniques.Originality/valueWhile the survey techniques described are well established in archaeological circles, the client‐oriented approach advocated here is not. Construction professionals dealing with historic buildings will find the approach of immediate practical benefit.

Purpose The purpose of this paper is to understand in-depth how consumers create value in their lives using WhatsApp, the leading mobile instant messaging (MIM) application. Design/methodology/approach The study adopts the perspective of customer-dominant logic (CDL) and uses a qualitative multimethod design involving 3 focus groups and 25 subsequent in-depth interviews. The research setting was Ecuador, a Latin American country. Findings Analysis and interpretation of the participants’ stories made it possible to identify and understand the creation of four types of value: maintaining and strengthening relationships; improving role performance; emotional support; and entertainment and fun. In addition, the present study proposes a conceptual model of consumer value creation as it applies to MIM. Practical implications Understanding the way consumers create value in their lives using MIM is important not only for organizations that offer MIM applications, but also for those companies that develop other applications for mobile phones or for those who wish to use MIM as an electronic word-of-mouth vehicle. Originality/value The current study is one of the first to address the topic of consumer behavior in the use of technologies from the perspective of CDL; this perspective enables an integrated qualitative vision of value creation in which the consumer is the protagonist.

Purpose The purpose of this paper is twofold: first, to understand data management challenges in e-maintenance systems from a holistically viewpoint through summarizing the earlier scattered research in the field, and second, to present a conceptual approach for addressing these challenges in practice. Design/methodology/approach The study is realized as a combination of a literature review and by the means of analyzing the practices on an industry leader in manufacturing and maintenance services. Findings This research provides a general understanding over data management challenges in e-maintenance and summarizes their associated proposed solutions. In addition, this paper lists and exemplifies different types and sources of data which can be collected in e-maintenance, across different organizational levels. Analyzing the data management practices of an e-maintenance industry leader provides a conceptual approach to address identified challenges in practice. Research limitations/implications Since this paper is based on studying the practices of a single company, it might be limited to generalize the results. Future research topics can focus on each of mentioned data management challenges and also validate the applicability of presented model in other companies and industries. Practical implications Understanding the e-maintenance-related challenges helps maintenance managers and other involved stakeholders in e-maintenance systems to better solve the challenges. Originality/value The so-far literature on e-maintenance has been studied with narrow focus to data and data management in e-maintenance appears as one of the less studied topics in the literature. This research paper contributes to e-maintenance by highlighting the deficiencies of the discussion surrounding the perspectives of data management in e-maintenance by studying all common data management challenges and listing different types of data which need to be acquired in e-maintenance systems.

Purpose The purpose of this study is to develop a profile of whistleblowers and to determine whether whistleblowing legislation would encourage those individuals to bring to light some illegal or unethical behaviour that otherwise would remain in the shadows. Design/methodology/approach Having identified whistleblowing correlation, a survey was carried out in Cyprus of actual whistleblowers and could-have-been whistleblowers. Findings Males between 46 and55 years of age, regardless of whether they have dependents or hold senior positions in organizations are significantly more likely to blow the whistle. However, could-have-been whistleblowers did not go ahead because they felt that the authorities would not act on their information. Research limitations/implications Because of the sensitive nature of the research topic and the fact that only whistleblowers or intended whistleblowers could participate in the study, the sample size is limited as a result. This, in turn, limits both the number of respondents in each category (actual and intended) as well as constrains the statistical analysis that could be carried out on the data. Practical implications It remains to be seen whether EU Member States shall implement the European Directive 2019/1937 on the protection of persons who report breaches of Union Law, in its entirety by the due date, namely December 2021. Originality/value This study provides a literature review of whistleblowing and reports an original survey against the backdrop of the European Directive.
