This paper aims to propose the five-phase sphere equivalent model of recycled concrete, which can be used to deduce the theoretical formulas for the Poisson’s ratio and effective elastic modulus.

At a mesoscopic level, the equivalent model converts the interfacial layer, which consists of the new interfacial transition zone (ITZ), the old mortar and the old (ITZ), into a uniform equivalent medium. This paper deduces a strength expression for the interfacial transition zone at the microscopic level using the equivalent model and elastic theory. In addition, a new finite element method called the base force element method was used in this research.

Through numerical simulation, it was found that the mechanical property results from the five-phase sphere equivalent model were in good agreement with those of the random aggregate model. Furthermore, the proposed model agree on quite well with the available experimental data.

The equivalent model can eliminate the influence of the interfacial layer on the macroscopic mechanical properties, thereby improving the calculation accuracy and computational efficiency. The proposed model can also provide a suitable model for multi-scale calculations.

This paper seeks to compare different national PR histories in order to unfold the degree of abstract reflection in PR history writing. It aims to provide some suggestions for a future PR historiography, based on this comparison.

The paper compares British, German, and US American PR historiography. The study is based on a comparison of 36 PR histories. A triple matrix of theoretization is used in order to differentiate the histories.

Within the comparison American PR historiography accounts for 24 public relations history approaches, whereas Great Britain (1) and Germany (11) offer fewer histories. However, this richness in quantity does not lead to theoretical diversification. Owing to the paradigmatic obligation to a progressivist understanding, American PR historiography actually entails only one theoretic approach, while its German equivalent includes three different theoretic approaches and British PR historiography – being at its start – at least contains one explicitly non‐progressivist, methodologically well‐informed, fact‐oriented example. Paradoxically, the prevailing American PR historiography, on the one hand, conceptualizes PR as a modern phenomenon but, on the other hand, claims even ancient beginnings.

The corpus of analysis contains only studies that attempt to supply an encompassing overview of (national) PR history.

Public relations managers may use these findings to achieve a more nuanced critical understanding of the history of their occupation, and thereby reflect on its current state, which may lead to intensified ethical endeavours.

The paper presents a pioneer systematic comparison of the three national PR histories, which may lead to enhanced national and general PR historiography. Another value is the establishment of a theoretically informed comparative measuring instrument, which (in future) can also be applied in order to compare and improve other national PR historiographies.

With 43.2 million coronavirus cases and 525,000 deaths in 2022, India ranked second worldwide, after the United States (84.6 million cases and 1 million deaths), according to the latest available June 2022 COVID-19 impact data.

Amid people’s growing mistrust in the government, India’s news media enhanced the nation’s distinguished designation as the world’s largest and most populous democracy. India’s news media inform, educate, empower, and entertain a surging population of 1.4 billion people, which is roughly one-sixth of the world’s people.

Drawing upon the media agendamelding theoretical framework, we conducted a case study research into interplay between two prominent democratic institutions, the media and the government, to analyze the role of the COVID-19 pandemic in redefining India’s networked society.

India’s COVID-19 pandemic aggravated internecine tensions between media and government relating to four key freedom issues: (1) world’s largest COVID-19 lockdown affecting 1.3 billion Indians from March 25, 2020 to August 2020 with extensions and five-phased re-openings, to restrict the spread of COVID-19; (2) Internet shutdowns; (3) media censorship during the 1975–1977 “Emergency”; and (4) unabated murders of journalists in India.

Although the COVID-19 pandemic caused deleterious problems debilitating the tensions between the media and the government, India’s journalists thrived by speaking truth to power. This study delineates key aspects of India’s media agendamelding that explicates how the people of India form their media agendas. India’s news audiences meld media messages from newspapers, television, and social media to form a picture of the issues, insights, and ideas that define their lives and times in the 21st century digital age.

Describes the current industrial scenario which is marked by the proliferation of theoretical ideas and concepts on total quality management (TQM) proclaimed by numerous quality management and engineering experts. Insists on the need to streamline these ideas and concepts so that TQM programmes in manufacturing firms are focused effectively towards quality enhancement strategies. Calls for replacing the traditional terminology, TQM, with that of strategic quality management (SQM) with an updated definition. Presents the main results of investigations made during a long research carried out in this direction which began with the identification of a TQM framework of reference on the basis of the old single manufacturer model and culminated in the evolution of a focused SQM system model. Concludes by briefing the major findings of the research and mentions the possibility of exploiting artificial intelligence techniques like expert systems for carrying out SQM practices more effectively.

Few studies have investigated the relationship between work-family human resource practices and firm-level outcomes. Several organizational studies have addressed the antecedents to firm adoption of work-family initiatives; however, the majority of work-family research investigates the relationship between work-family practices and individual-level outcomes. The current paper begins by providing a critical analysis and synthesis of the extant work-family literature. In addition, we integrate the organizational learning research on firm commitment to work-family policies and the human resource model. We suggest that the level of firm commitment moderates the relationship between work-family policies, the human resource model, and firm performance. Several propositions for future work-family research are presented.

This article reviews the historical development of the treatment of religious organizations in journals centered on religion.

The article asks four questions: (1) Are religious organizations different from other kinds of organizations? (2) What factors produce differences or similarities between religious and other organizations? (3) Are religious organizations different from each other?

Differences from other kinds of organizations are based in beliefs/theology. But there is a constant concern with the bureaucratization of religious organizations as they are subject to general organizational influences such as scale and geographical dispersion. However, it is argued that these general influences emanate from belief systems. We suggest the need for a renewed attention to a comparative organizations perspective in organization theory – one that appreciates the similarities and differences between sectors and within sectors.

Not only are there differences between religious and nonreligious organizations, but there are also substantial differences between religious organizations. There are also similarities between religious and nonreligious organizations, as well as similarities between religious organizations. The way forward for both the study of religious organizations and organizational theory in general is to look for explanations for these similarities and differences.

The authors conducted an action research study with the aim of understanding current commercial offerings in modular designs in virtual environments and to explore modularity development based on consumer input for the purpose of personalizing three-dimensional (3D) virtual fashion stores.

Through five phases of diagnosing, action planning, action taking, evaluating and specifying learning, the authors attempted to diagnose the current commercial offerings of modular designs in virtual spaces and to identify the right type and the number of modules and modular options for personalizing 3D virtual stores based on consumers' actual designs and focus group input. The authors then further conceptualized modules to serve as an example for developing modularity in 3D virtual reality (VR) stores.

In the diagnosing phase, the authors investigated the modularity structure of cocreating a retail store in two popular virtual worlds: Second Life and The Sims 4. In the evaluation phase, the authors identified modules and modular options for personalizing 3D virtual stores based on a content analysis of consumers' post-design focus group discussions. In the last phase (specifying learning), the authors conceptualized a total of nine modules and 38 modular options for personalizing 3D virtual stores, including style, price point, product category, color, presence of avatar, virtual product try-on, music, product recommendation and product customization.

The significance of this study lies in the pioneering methodological work of identifying, creating and visualizing 3D VR modular store options based on consumer input and in improving the authors’ understanding of current commercial offerings. This study also enriches design theories on cocreation systems. The authors’ suggested modules for personalizing 3D virtual stores could inspire future evidence-based designs to be readily used by VR retailers as well extend the application of mass customization theory from the realm of product development to retail environments.

The purpose of this paper is to develop a conceptual foundation for understanding business-to-business (B2B) interactions at trade fairs.

The paper reports a qualitative study that was undertaken to gain in-depth insights into the relevance of the trade fair context for business relationships. Key informants were trade fair organizers, trade fair exhibitors, trade fair visitors and experts in the field.

Based on a qualitative approach, we propose a conceptual model that allows understanding the importance of relational interactions at B2B trade fairs. The model shows that interactions and networking served through information exchange, and social interaction among participants at B2B trade fairs are vital for relationship building and development. The model also highlights the fact that trade fairs are relevant to develop a relationship marketing strategy that involves interactions and networking with a multitude of players that goes beyond the interactions between exhibitors and visitors. The model also depicts the importance of trade fairs for product innovation and for generating innovative solutions to problems. Overall, findings suggest that a customized approach will become dominant in trade fairs.

This paper’s contribution is twofold: first, to the relationship marketing literature for developing an understanding of the influence of a specific context in promoting particular interaction dynamics capable of affecting relationship development; second, to the literature on trade fairs by focusing on such context from a relationship marketing perspective.

Reasonable remuneration of employee inventions is a controversial issue causing court litigations among employees and employers in many countries. The paper aims to shed light on the missing economic interpretation of the reasonable remuneration of employee inventions. Specifically, it focuses on the concept of “reasonability” at the issue.

In an empirical qualitative multiple case-study setting, the paper explores inductively Czech corporate employee inventors' remuneration systems, using typological analysis and M. Weber's interpretative theoretical construct of “ideal type.”

At the first level, reasonability is a function of multi-amount rewarding, a certain level of total remuneration and identifiable benefits being a decisive factor. Additionally, the reasonability is conceptualised as a function of two dimensions – timing/risk and benefit–reward relation. At the second level, the reasonability is interpreted as a concept balancing seven points of view: timing, materiality, equity, risk management, transparency, system costs and exactness. At the third level, the paper offers an optimal remuneration system like the one that optimises developed seven-criterion framework.

Even if analysed within one-country and nine-company context, the insights are generalisable across a broader sample of countries with statutory rules for employee inventions. Studying more cases may enrich the findings. The findings are based merely on a rational perspective and do not deal with psychological aspects of employees.

The results may be helpful for intellectual property or R&D managers in building or reorganising employee invention remuneration systems within corporations. The developed seven-criteria model can serve as a discussion framework; the suggested optimal system as a reference point. The results may serve as well to consultants, judges or other parties involved in currently growing employee–employer controversies and litigations. The analysis may fuel public policy decisions, too.

The paper brings unique and detailed empirical insights into the issue of employee inventions. It offers a complex multi-perspective (employee/employer) framework through which the reasonability can be discussed and suggests an optimal system, which can serve as a reference point.

This paper aims to examine whether the perceived pressures from stakeholders with high potential to cooperate and/or threaten the firm’s survival affect the decision to adopt carbon management strategies (CMSs).

A logistic panel regression model is estimated using longitudinal data from Australia’s Top-200 listed firms over seven years from 2009 to 2015. The authors test the firm’s propensity to adopt CMSs conditioned on the influence of four groups of stakeholders: the regulators, institutional investors, media and creditors. Data on CMSs adopted by firms are sourced from Thomson Reuters ASSET4 database, the Carbon Disclosure Project survey, annual reports, company websites and sustainability reports.

The authors show that stakeholder pressures are associated not only with the adoption or non-adoption of CMSs but also with the type of CMSs adopted. Three types of CMSs are identified, namely, compensation, reduction and innovation strategies. The findings reveal that CMS adoption and the firms’ propensity to adopt compensation and reduction strategies are significantly related to perceived pressures from the regulators, media and creditors. While pressure from the regulators is also associated with the firms’ propensity to adopt innovation strategies, a more advanced type of CMSs, the potential pressure from the media and creditors are not significantly related.

The findings imply that a firm’s adoption of CMSs is not merely about managing stakeholders in the regulatory sphere but also about taking into account the perceived pressures from non-regulatory stakeholders and the context-dependent nature of their influences. The authors show that by influencing the voluntary disclosure of carbon emissions, the government continues to be effective in encouraging firms to take action on climate change despite the abolition of the carbon tax in Australia.

This study highlights that, apart from a heavy-handed approach, regulators can adopt softer forms of regulation such as the National Greenhouse and Energy Reporting (NGER) Act and a less invasive, stakeholder-driven approach to encourage firms to adopt CMSs and thereby work towards climate change mitigation.

This study extends the literature by showing that perceived pressure from some stakeholders found to be influential in relation to some corporate decisions (such as environmental strategy adoption and climate-change-related disclosure) may not necessarily be influential in relation to CMS adoption.
