Abstract

Explores the relationships between teacher perceptions of the structural coupling in their schools and their perceptions of school robustness and effectiveness in a research study of 73 participating schools. Pearson product‐moment correlations of mean scores from each school produced significant relationships, suggesting that teacher perceptions of relatively tight coupling of goal direction/vision and work supervision structures, and relatively loose coupling of manipulative control structures, are associated with their positive perceptions of school robustness and effectiveness as well as student achievement and attendance.

Abstract

Purpose

This paper aims to develop mathematical models of variously compensated wireless energy transfer (WET) systems. Attention is primarily paid to the derivation of the most important energy transfer characteristics such as efficiency and amount of transferred power. This paper discusses the main advantages and disadvantages of various compensation techniques to show their possible application areas. On the basis of these results, a designer will be able to quickly identify which compensation type suites as the best solution to fulfill a given system’s requirements.

Design/methodology/approach

First, the current state in the field of mathematical modeling of WET systems is introduced. Next, the non-resonant magnetic-coupled circuit together with four most common resonant magnetic-coupled circuits is analyzed. The equivalent circuit models using loop currents methodology is applied to the analyses. The proposed methodology is experimentally verified by the laboratory measurement of selected circuit topology. The main contribution of the proposed methodology lies in its quick applicability on more complicated or extended systems while keeping a relatively good match with the real system’s behavior.

Findings

The authors have presented the usage of a simple and accurate methodology for investigating variously compensated WET systems. Electrical engineers who require effective and powerful tools for the identification of basic WET systems properties will find this methodology to be of extensive help.

Research limitations/implications

The analyses consider only the sinusoidal type of supply voltage; so, it is valid mainly for the close range of the resonant state. Nonlinearities cannot be taken into account.

Practical implications

This research may be applied in the field of WET systems.

Originality/value

Research in the area of power electronic systems, which provides a clear and straightforward procedure for WET system identification, will be helpful to most practical technicians who are not well versed in areas of physical-based phenomena.

Abstract

Purpose

The purpose of this paper is to analyse the drivers of sustainable entrepreneurial practices in SMEs operating in a developing economy. The secondary objectives are to explore the relationship between these drivers and to draw out the implications for policy and practice.

Design/methodology/approach

The paper is informed by the literature on sustainable entrepreneurship, and on the drivers of pro-environmental practices in SMEs. It reports on the results of an intensive multi-level empirical study, which investigates the environmental practices of SMEs in Pakistan’s leatherworking industry using a multiple case study design and grounded analysis, which draws on relevant institutional theory.

Findings

The study identifies that coercive, normative and mimetic isomorphic pressures simultaneously drive sustainable entrepreneurial activity in the majority of sample SMEs. These pressures are exerted by specific micro-, meso- and macro-level factors, ranging from international customers’ requirements to individual-level values of owners and managers. It also reveals the catalytic effect of the educational and awareness-raising activities of intermediary organisations, in tandem with the attraction of competitiveness gains, (international) environmental regulations, industrial dynamism and reputational factors.

Practical implications

The evidence suggests that, in countries where formal institutional mechanisms have less of an impact, intermediary organisations can perform a proto-institutional role that helps to overcome pre-existing barriers to environmental improvement by sparking sustainable entrepreneurial activity in SME populations.

Originality/value

The findings imply that the drivers of sustainable entrepreneurial activity do not operate in a “piecemeal” fashion, but that particular factors mediate the emergence and development of other sustainability drivers. This paper provides new insights into sustainable entrepreneurship and motivations for environmental practices in an under-researched developing economy context.

Abstract

Over the last two decades, growing concerns about eroding ecosystem quality have led to a renewed interest in environmentalism. Such concerns have prompted purchasing professionals to reassess their current purchasing strategy. To help purchasing professionals configure an environmentally conscious (green) purchasing strategy, the empirical findings from a survey of US firms with greater environmental risks are reported. Based on the empirical findings, aims to identify variables that either promote or inhibit the successful implementation of green purchasing and to evaluate the effects of green purchasing on the firm’s supplier selection, waste management, packaging, and regulatory compliance.

Abstract

Purpose

Voluntary corporate social responsibility reporting has developed into an everyday activity for many commercial organizations, and scholarly interest in these practices continues to increase. This paper focusses on one subset of these disclosures, namely the figures relating to environmental expenditures and investments published by various organizations. The purpose of this paper is to provide insights into the nature, role and significance of such financial environmental information. Despite their seeming accuracy and preciseness, little is known about how such financial environmental information is constructed and subsequently used in organizational settings.

Design/methodology/approach

The paper is based on a qualitative case study focussing on a Finnish energy company. The authors build the investigation primarily on 26 semi-structured interviews with employees at all organizational levels, which the authors supplement with various documentary sources. The interpretation draws on the notion of loose coupling, which the authors use as a method theory to provide a better understanding of this complex organizational practice.

Findings

The authors highlight the ambiguous and imprecise nature of the outwardly accurate figures provided by the company. The authors argue that disclosed financial environmental information is only loosely coupled with various dimensions, including the organization’s actual activities, its environmental impacts and organizational decision making.

Originality/value

The findings contrast with those of some prior research, which has considered financial environmental information highly valuable. As for broader implications, the paper discusses the accuracy of public records based on such ambiguous organizational figures.

Abstract

Purpose

The purpose of this study is to examine how multi-tier suppliers respond to the institutional pressures for the implementation of sustainable supply management (SSM) practices in supply chains, and what institutional logics allow them to do so.

Design/methodology/approach

This study employs a qualitative research design, drawing on data from semi-structured interviews with 46 owners and managers of multi-tier suppliers and 18 key informants of diverse stakeholders. Following an abductive approach, institutional theory conceptually guides the analytical iteration processes between theory and interview data.

Findings

The findings demonstrate two kinds of thematic responses to institutional pressures – coupling (good side) and decoupling (dark side) of the supply chain – used by the factory management of multi-tier suppliers. This paper also identifies multiple institutional logics – market-led logic, values-led logic and holistic sustainability logic – that are perceived to conflict (trade-offs) and complement (synergies) the SSM implementation.

Research limitations/implications

By investigating the perspectives of the factory management of upstream apparel suppliers, this study enhances the understanding of the connection between (de)coupling responses and institutional logics inside the multi-tier supplier firms. Further research would be required to include more downstream tiers including the ultimate users.

Practical implications

The findings may be of particular attention to brand-owning apparel retailers, industry leaders and policymakers who are seeking to understand multi-tier suppliers' challenges, conflicts and (de)coupling responses, and become aware of how they can be dealt with.

Originality/value

This study contributes to and expands the embryonic research stream of sustainable multi-tier supply chain management by connecting it to the wider application of institutional theory.

Abstract

Purpose

This study aims to examine the research output on climate change, environmental risks and insurance from 1986 to 2020, thereby revealing the development of the literature through collaborative networks. The relationship between insurance, climate change and environmental threats has gained research attention. This study describes the interaction between insurance, climate change and environmental risk.

Design/methodology/approach

This study is a bibliometric analysis of the literature and assessed the current state of science. A total of 97 academic papers from top-level journals listed in the Scopus database are shortlisted.

Findings

The understanding of climate change, environmental risks and insurance is shaped and enhanced through the collaborative network maps of researchers. Their reach expands across different networks, core themes and streams, as these topics develop.

Research limitations/implications

Data for this study were generated from English-written journal articles listed in the Scopus database only; subsequently, this study was representative of high-quality papers published in the areas of climate change, environmental risks and insurance.

Practical implications

The results of this study can be useful to academic researchers to aid their understanding of climate change, environmental risks and insurance research development, to identify the current context and to develop a future research agenda.

Social implications

The findings of this study can improve the understanding of industry practitioners about climate change and global warming challenges, and how insurance can be used as a tool to address such challenges.

Originality/value

This study is a novel attempt. To the best of the authors’ knowledge, this is one of the first studies to better understand climate change, environmental risks and insurance as a research topic by examining its evolution in an academic context through visualization, coupling and bibliometric analysis. This bibliometric study is unique in reviewing climate change literature and providing a future research agenda. Using bibliometric data, this study addressed the technical aspects and the value it adds to actual practice. Bibliometric indicators quantitatively and qualitatively evaluate emerging disciplinary progress in this topic.

Abstract

Purpose

The purpose of this chapter is fivefold. First, it highlights that, despite apparent progress, business in general, and marketing in particular, has made little impact upon environmental sustainability. Second, it offers four explanations for the persistent challenges that contribute to this lack of meaningful progress. Third, it presents two theoretical lenses (i.e., assemblage theory and socio-ecological systems theory) for viewing environmental sustainability from new perspectives. Fourth, it offers a mid-range theory, biomimicry, to bridge the gap between these higher-level theories and managerial decisions on the ground. Finally, it offers implications and ideas for future research based on these persistent challenges and new perspectives.

Methodology/approach

Our paper is theoretical in focus. We offer a conceptual analysis of persistent challenges facing business efforts in environmental sustainability and suggest useful lenses to integrate marketing decisions more closely with our natural environment.

Findings

We present biomimicry as an actionable framework that seeks inspiration from nature and also explicitly grounds marketing decisions in the natural world.

Practical Implications

Our paper draws attention to the challenges facing firms seeking to achieve better performance in environmental sustainability. In addition, it offers a set of fresh theoretical perspectives as well as future issues for scholarly research in this domain.

Originality/value

Our work is designed to be provocative; it articulates reasons why business efforts in environmental sustainability do not scale to meaningful impact upon our planet and explores theoretical lenses by which those efforts could be more impactful.

Abstract

Digital twin (DT) is an emerging technology that enables sophisticated interaction between physical objects and their virtual replicas. Although DT has recently gained significant attraction in both industry and academia, there is no systematic understanding of DT from its development history to its different concepts and applications in disparate disciplines. The majority of DT literature focuses on the conceptual development of DT frameworks for a specific implementation area. Hence, this paper provides a state-of-the-art review of DT history, different definitions and models, and six types of key enabling technologies. The review also provides a comprehensive survey of DT applications from two perspectives: (1) applications in four product-lifecycle phases, i.e. product design, manufacturing, operation and maintenance, and recycling and (2) applications in four categorized engineering fields, including aerospace engineering, tunneling and underground engineering, wind engineering and Internet of things (IoT) applications. DT frameworks, characteristic components, key technologies and specific applications are extracted for each DT category in this paper. A comprehensive survey of the DT references reveals the following findings: (1) The majority of existing DT models only involve one-way data transfer from physical entities to virtual models and (2) There is a lack of consideration of the environmental coupling, which results in the inaccurate representation of the virtual components in existing DT models. Thus, this paper highlights the role of environmental factor in DT enabling technologies and in categorized engineering applications. In addition, the review discusses the key challenges and provides future work for constructing DTs of complex engineering systems.

Abstract

Purpose

The purpose of this paper is to argue that it is time for change in the way the paper teach, theories and practice accounting. Traditional accounting practice constructs the identity of the accountable entity as purely self-interested. Yet, there is evidence that firms do engage in broader activities. This paper aims to explain and illustrate that there are groups of firms that engage in socially responsible activities, yet their accounting systems still assume autopoietic behavior. Accounting should resonate with social expectations, but at present it does not.

Design/methodology/approach

Literature concerning theories of biological autopoiesis and social equivalents are reviewed. They are related to accounting practices, and to concepts of open and closed systems. The theories are related to survey results of socially responsible activities practiced by firms. National surveys undertaken in New Zealand at three-year intervals are the basis of the empirical content of the paper.

Findings

There is evidence that firms behave socially and environmentally responsibly. Yet accounting practice does not encourage such behaviour. Accounting practice has to be able to construct the identity of the accountable entity so that it pursues more than its own self-interest, and resonate with societal expectations.

Research limitations/implications

The paper is unconventional. It challenges extant practice. Its theoretical content may not appeal to many traditional accountants.

Originality/value

The theory and empirics are original. The theory of autopoiesis is illustrated through survey evidence of business practices.
