Over the last decade, circular economy (CE) has gathered interest from both industrialists and academics alike. Whilst CE research is widespread in such areas as supply chain and larger organisations, there is limited research into how small to medium enterprises (SMEs) can prepare for adopting CE. There is no comprehensive readiness model for SMEs adopting CE. The purpose of this paper is to explore the literature on change readiness and generate knowledge to fill this gap by developing a conceptual model to measure change readiness for SMEs' adopting CE.

This study is based on a comprehensive literature review of change readiness models and frameworks. The paper reviews publications from Science Direct, Web of Science, Emerald, Scopus and Google Scholar. The readiness for change models and frameworks from the selected publications are evaluated and synthesised to develop a comprehensive conceptual model for change readiness for SMEs adopting a circular economy.

A readiness conceptual model is developed by incorporating several factors as precursors to readiness, i.e. individual/collective difference, structural, contextual factors and related barriers. Eleven factors make up the individual/collective difference. Three factors make up the structural and contextual factors.

This paper develops a conceptual model that can aid academics and practitioners in better understanding SMEs readiness to adopt CE.

This paper makes a unique contribution by proposing a comprehensive conceptual model of readiness for SMEs adopting CE.

Most of the emphasis in the green building literature on the green performance of buildings has been on optimizing energy and resource efficiency. Admittedly, from the perspective of the sustainable construction industry, making optimally energy and resource efficiency, often seen as a technical challenge, has a premise role in green building projects. However, green buildings need to optimally meet the health, well-being and comfort requirements of their occupants and their environmental quality targets. In that context, perceived quality is a crucial determinant of occupant satisfaction and can play a critical role in the user-oriented improvement of the green performance of buildings. While previous research has highlighted issues related to occupant satisfaction, none of them examines green buildings from a perceived quality perspective. Therefore, the study attempts to fill this research gap.

Firstly, to reveal the positive and negative satisfaction of the building occupants according to the green building features, the review of previous research in the related literature is supplemented by an exploratory study of case studies evaluating occupant satisfaction in green buildings. Then, a conceptual framework is proposed to link perceived quality and green building features towards occupant satisfaction.

A review of the case studies in 49 research articles has shown deficiencies in a comprehensive understanding and approach to the perceived quality of green buildings. In response, the development of a framework for conceptual interrelationships may provide a pathway for more detailed quality assessments for future research. In this study, the proposed conceptual framework has the potential to provide a conceptual basis for future models in determining the relationship between quality expectations and quality experiences in green buildings. It can also serve as a constructive approach for assessing occupant satisfaction in the quality-driven improvements of green buildings and further investigation of the importance of various quality cues, quality attributes and their interactions.

This study aims to incorporate green building features and perceived quality concepts into a framework that can form the basis for assessing occupant satisfaction in green buildings. The ultimate goal of the proposed conceptual framework is to generate an insight that can contribute to rethinking the perceived quality of green buildings and developing more occupant-driven solutions for future green buildings.

The purpose of this paper is to enhance conceptual understanding of reporting boundaries in corporate annual reports by developing a conceptual framework of the rules and principles, referred to here as dimensions, underlying boundaries. A total of nine contemporary regulations/guidelines are compared in terms of the boundary dimensions identified to illustrate similarities and differences in boundary concepts.

To develop a conceptual framework of reporting boundary dimensions, academic and industry literature were analysed to identify boundary dimensions. Thereafter, nine contemporary regulations/guidelines were compared in terms of these dimensions. A qualitative approach was taken including document analysis and content analysis.

A total of 10 key boundary dimensions were identified through analysis of academic and industry literature. Each dimension represents a continuum along which regulations/guidelines can position themselves. Taken together, the 10 dimensions provide a comprehensive description of the chosen boundary concept.

The paper contributes to accounting theory by providing a holistic conceptual framework of dimensions relating to reporting boundaries, thus answering calls for more conceptual development of the boundary construct. The conceptual framework and comparison of contemporary regulations/guidelines adds to scarce literature considering financial and non-financial boundaries simultaneously, which is relevant for annual reports. From a practical perspective, the paper brings renewed visibility to boundaries with implications for preparers, users, standard setters and auditors of annual reports.

This paper is a summary of a successfully defended doctoral dissertation. The purpose of this paper is to place this research in context to emerging areas of project management and service science, management and engineering and to encourage others to embark on further research related to this important topic.

Results reported in this paper were based upon action learning from research in which a project management tool for estimating deployment cost was developed by capturing the knowledge of subject matter experts (SMEs) and subsequently tested against projects from various geographic areas.

There were two primary findings. A development and analysis of the conceptual estimating framework supports the assertion that the use of the framework provides an awareness of the project that may not otherwise be observed or, at best, would be observed later in the life of the project and potentially addressed at a higher cost. A strong association has been found between the conceptual estimate produced by the comprehensive framework and the conceptual estimate produced manually through the use of SMEs.

From academic perspective, the synthesis of technology management, business processes, and the conceptual estimating framework enhances the body of knowledge of project management. For practical applications, the method and framework employed can be utilized to build functioning conceptual estimating tools for deployment, which can lead to cost savings during the estimating process and, as this study surmises, will lead to more effective project management, control, and implementation.

The purpose of the present paper is to obtain the capability of designing modern rotorcrafts with enhanced accuracy and reliability.

Among the existing rotorcraft design programs, an appropriate program was selected as a baseline for improvement. It was based on a database comprising conventional fleets of rotorcrafts. The baseline program was not robust because it contained a simple iteration loop, which only monitored the gross weight of the aircraft. Therefore, it is not accurate enough to fulfill the quality and sophistication of a conceptual design framework useful for present and future generations of rotorcrafts. In this paper, the estimation formulas for the sizing and weight of the rotorcraft subsystem were updated by referring to modern aircraft data. In addition, trend curves for various turboshaft engines available these days were established. Instead of using the power estimation algorithm based on the momentum theory with empirical corrections, blade element rotor aerodynamics and trim analysis were developed and incorporated into the present framework. Moreover, the simple iteration loop for the aircraft gross weight was reinforced by adding a mathematical optimization algorithm, such as a genetic algorithm.

The improved optimization framework for rotorcraft conceptual design which has the capability of designing modern rotorcrafts with enhanced accuracy and reliability was constructed by using MATLAB optimization toolbox.

The optimization framework can be used by the rotorcraft industries at an early stage of the rotorcraft design.

It was verified that the improved optimization framework for the rotorcraft conceptual design has the capability of designing modern rotorcrafts with enhanced accuracy and reliability.

This study aims to develop an original conceptual framework to guide research into knowledge transmission between professional external knowledge providers and their business clientele. As such, the framework aims to bridge a gap between theory and practice by explicating the processes which affect knowledge transmission and the conversion of knowledge for business application (i.e. knowledge transference).

Key concepts from disciplines of knowledge management, information management, communications, services marketing and business advice are reviewed and integrated into the development of this framework. Underpinned by a critical realist philosophical lens, it provides a robust research guide for examining business advisor knowledge actions in a changing open environment.

This study identifies that the process of knowledge transmission from a source external to a business is more complex than internal knowledge sharing. It addresses this complexity through a knowledge transmission framework, in a research design that is applicable to any methodological paradigm. Real-world application is identified in its applicability for evaluating mechanisms to facilitate knowledge transmission practices of external advisors to small business in regionally isolated communities.

The critical realist research methodology allows for causality in knowledge transmission to emerge; however, no assertion is made that the conceptual framework developed needs any particular philosophical paradigm for its application. Instead, what is asserted is that the research framework developed in this paper is specifically suited to the characteristics of external knowledge providers, their tacit knowledge and the businesses they service.

This study reconceptualises various theoretical perspectives and develops a sequential process for addressing a research lacuna by specifically examining the processes (or connections) between external business advisor’s knowledge and their advisory actions. With these processes clearly established, the role of external knowledge providers, as knowledge transmitters, deepens the understanding of knowledge transference that up until now has focused typically on internal organisation aspects.

The application of good buildability practices is vital for improving the performance of projects and businesses in the construction sector. Despite the plethora of research into buildability in construction in the previous years, there is little information concerning how buildability practice can be successfully implemented. This paper aims to develop a conceptual framework that explains how buildability practice can be implemented successfully in the construction industry.

The paper uses an integrative literature review method to synthesise literature from different domains to describe various themes by which buildability assessment can be successfully implemented in the construction industry.

The findings of the review of literature conceptualised a buildability implementation framework at four principal themes: buildability attributes for improving the practice of construction management, factors supporting the implementation of buildability assessment, measures for improving the buildability of building designs and factors impeding the implementation of buildability assessment.

The outcome of this study contributes to knowledge in three different ways. First, the framework emerging from this study provides guidance to stakeholders on strategies for the successful implementation of buildability. Second, the information gathered in this study is useful for the development of buildability assessment tool. Finally, the framework has a potential of improving the practice of embedding buildability into designs. The detailed descriptions of the relevant variables at each principal theme advance the understanding of buildability in the construction industry and are fundamental to developing buildability assessment tools for the industry.

Digital technology has changed how people interact with information and each other. Being able to access and share information ensures healthcare practitioners can keep abreast of new and ever changing information and improve services. The purpose of this paper is to present an information management-knowledge transfer (IM-KT) framework which emerged from a study looking at digital literacy in the occupational therapy profession.

The research was undertaken in three stages. First an in-depth literature review was undertaken, which enabled the creation of an initial conceptual framework which in turn, informed the second stage of the research: the development of a survey about the use of digital technologies. Occupational therapy students, academics and practitioners across five different countries completed the survey, after which refinements to the framework were made. The IM-KT framework presented in this paper emerged as a result of the third stage of the study, which was completed using the Delphi technique where 18 experts were consulted over four rounds of qualitative questionnaires.

The IM-KT framework assists individuals and groups to better understand how information management and knowledge transfer occurs. The framework highlights the central role of information literacy and digital literacy and the influence of context on knowledge transfer activities.

The IM-KT framework delineates clearly between information and knowledge and demonstrates the essential role of information literacy and digital literacy in the knowledge era. This framework was developed for the occupational therapy profession and may be applicable to other professions striving to keep up to date with best evidence.

Industry 4.0 is one of the most emergent research topics attracting significant interest by researchers as well as practitioners. Many articles have been published with regards Industry 4.0; however, there is no research that clearly conceptualizes Industry 4.0 in the context of supply chain. This paper aims to propose the term “Supply Chain 4.0” together with a novel conceptual framework that captures the essence of Industry 4.0 within the supply chain context. As Industry 4.0 is inherently a revolution, and as revolutions are evolutionary, this research also aims to capture the evolution of Supply Chain 4.0 from maturity levels perspective to facilitate the formulation and development of Supply Chain 4.0 strategy.

Following a deductive research approach and a qualitative strategy, a systematic literature review (SLR) was adopted as the research method seeking to understand the relationships among supply chain, Industry 4.0 and maturity levels research. The three phases of the SLR process utilized are: planning, conducting and reporting. A concept-oriented technique was applied to the outputs of the SLR to obtain the key constructs that would facilitate the development of the conceptual Supply Chain 4.0 framework.

The SLR showed that there is limited research linking Industry 4.0 to supply chain. Nevertheless, it was possible to extract a set of thematic categories from the analysis of the articles which are referred to as constructs as they form the core of the conceptual Supply Chain 4.0 framework. These constructs are managerial and capability supporters, technology levers, processes performance requirements and strategic outcomes. Each of these constructs consists of a number of elements which are referred to as “dimensions” in this research and a total of 21 dimensions were identified during the SLR. The SLR also demonstrated that maturity propositions for Industry 4.0 are still embrionary and entirely missing in the context of supply chain. Hence, this research develops and proposes a maturity levels framework that is underpinned by the core constructs of Supply Chain 4.0 and the corresponding dimensions. As these proposed frameworks are conceptual, this research also identifies and proposes several research directions to help fortify the Supply Chain 4.0 concept.

This research argues that the frameworks are robust because the constructs and dimensions are grounded in the literature, thus demonstrating both theoretical and practical relevance and value. As Supply Chain 4.0 research is still in infancy, there is a range of open research questions suggested based on the frameworks that could serve as guides for researchers to further develop the Supply Chain 4.0 concept. Also, practitioners can use this framework to develop better understanding of Supply Chain 4.0 and be able to evaluate the maturity of their organizations. As the proposed frameworks are conceptual, they require further empirical research to validate them and obtain new insights.

The SLR demonstrated a clear gap in literature with regards to Industry 4.0 in the context of supply chain, and also in the context of Industry 4.0 maturity levels for supply chain. This research is unique as it formulates and introduces novel frameworks that close these gaps in literature. The value of this research lies in the fact that it makes significant contribution in terms of understanding of Supply Chain 4.0 with a clear set of constructs and dimensions that form Supply Chain 4.0, which provides the foundation for further work in this area.
