Purpose This study aims to examine exergy efficiency of engines and entropy performances at the flight process. In addition, the improvements that can be achieved in the system with the effective parametric controls of the engine have been evaluated in terms of both efficiency and entropy in the system. Design/methodology/approach According to the flight characteristics of the engine, the altitude-dependent irreversibilities and their environmental effects were discussed with two developed indicators, energy performance indicator (EPI) and sustainability indicator (SI). Findings According to the results of both indicators, the energy efficiency potential of the engine during the flight process was found to be 15.02%, while the fuel-based efficiency potential was 18.84%. Research limitations/implications It is limited by the flight process of a Turboprop engine. Practical implications The management tools and criteria of entropy are very difficult model studies. The study offers an evaluable approach based on two basic criteria developed for engines. Social implications In monitoring and review of entropy management related to fossil fuel technologies, key indicators developed can be used as benchmarks for managing emission sources Originality/value The two basic indicators developed can be used as monitoring measurement tools of sustainable energy and environmental performances for engines and applications.

Purpose – The purpose of this paper is to stimulate interest in the use of quality management methods and tools and to provide a basis and direction for further improvement in the global brewing industry. Design/methodology/approach – The methodology that is followed in the paper is based on the study of quality management tools and best practices in global brewing companies. Findings – From all evidence found by this research, the conclusion is that quality management can dramatically improve certain operations and reduce cost or increase profit as well. All of the global brewing companies examined in this paper have their quality policies and each one of them uses what fits best to its business profile. Research limitations/implications – This study refers to some of the largest brewing companies in the world. Future research could be addressed toward the analysis of other smaller brewing companies, which are characterized by the concepts of quality management. Practical implications – The analysis of quality management in the global brewing industry may cause the interest of other brewing companies and other stakeholders affected by this industry. Quality tools can be very useful for dealing with problems and improving procedures in a brewery. Furthermore, the extension of this work with detailed references to these tools could produce a quality guide for brewing companies. Originality/value – The value of this paper lies in the identification and presentation of tools and quality policies which have been successfully developed by global brewing companies and may as well be implemented by others.

Purpose Describes how Agile teams can use strategic management tools and processes to discover market-creating innovations. Design/methodology/approach The related article “The next frontier for Agile: strategic management” in the previous issue of Strategy & Leadership explored the theory and possibilities of enterprise-wide Strategic Agility, a combination of Agile mindset and processes with strategic management theory to produce continuous market-creating innovation. This second installment offers insights from noted practitioners about implementing it. Findings The strategic concepts of Kim & Mauborgne’s Blue Ocean Strategy, Clayton Christensen’s Job to Be Done theory and Curt Carlson’s SRI Playbook – Need, Approach, Benefits per costs and Competition (NABC) can be adopted by Agile teams seeking innovations that create new customer value. Practical implications Identifying a well-defined Job to Be Done produces the start of an innovation blueprint which is unlike the traditional marketing concept of “needs” because of the much higher degree of specificity required to identify precisely what problem your potential solution would address. Originality/value Using strategic management concepts, Agile teams can redefine how needs are being met and in the process, discover value for customers from offering something or doing something that the company or the industry currently doesn’t provide.

PurposeThe purpose of this paper is to examine the quantitative measurement tools used in fields of study related to coproduction, as an approach to mobilizing knowledge, in order to inform the measurement of impact.Design/methodology/approachAn overview methodology was used to synthesize the findings from prior instrument reviews, focusing on the contexts in which measurement tools have been used, the main constructs and content themes of the tools, and the extent to which the tools display promising psychometric and pragmatic qualities.FindingsEight identified reviews described 441 instruments and measures designed to capture various aspects of knowledge being mobilized among diverse research stakeholders, with 291 (66%) exhibiting relevance for impact measurement.Research limitations/implicationsFuture studies that measure aspects of coproduction need to engage more openly and critically with psychometric and pragmatic considerations when designing, implementing and reporting on measurement tools.Practical implicationsTwenty-seven tools with strong measurement properties for evidencing impact in coproduction were identified, offering a starting point for scholars and practitioners engaging in partnered approaches to research, such as in professional learning networks.Originality/valueCurrent quantitative approaches to measuring the impacts of coproduction are failing to do so in ways that are meaningful, consistent, rigorous, reproducible and equitable. This paper provides a first step to addressing this issue by exploring promising measurement tools from fields of study with theoretical similarities to coproduction.

PurposeUrban sustainability is an inseparable dimension of today's cities; thus, the role played by creativity, and consequently sustainable urban entrepreneurship and the networks it raises, gives rise to the pro-activity of these two constructs toward a tripartition (economic, social and environmental). This study aims to measure sustainable urban entrepreneurship through a composite of existing indicators in the literature of cities.Design/methodology/approachIn this study, the authors followed a quantitative research by applying exploratory factor analysis. The sample contains 308 towns and cities in Portugal, and the data were collected using secondary databases (e.g. INE; PORDATA).FindingsThrough quantitative research, this study identified the key indicators that mediate sustainable urban entrepreneurship in cities, as a methodological tool for them to evaluate their sustainable entrepreneurial capacity.Practical implicationsThe results obtained here provide information to show that sustainable urban entrepreneurship is an essential construct for cities, allowing a solution to many of their urban problems by its association with creative economy and its influence on the revitalization of urban spaces by urban regeneration, and by the importance of networks in these, the latter being another fundamental construct.Originality/valueThis research makes important contributions to studies considering the sustainability construct in urban entrepreneurship area. It will help to fill part of the gap in existing studies involving the cities’ aspects in entrepreneurship field. Consequently, the main contribution of this study lies in identifying the indicators that contribute to cities' tripartite sustainable balance by assuming sustainable urban entrepreneurship as a crucial premise.

PurposeThe main purpose of this research is to analyse the efficiency of the main European monitoring frameworks to estimate the transition of the countries within the European Union (EU) towards circular economy (CE) using the example of Croatia.Design/methodology/approachAssessment methods with reliable data and appropriate indicators are essential when it comes to measuring transition and progress towards CE. The methodology employed in this research is a systematic and critical analysis of the seven European measurement frameworks employed to assess Croatia's progress towards CE.FindingsThe analysis revealed how EU's monitoring frameworks have developed over time and how useful they are in evaluating country's progress towards CE. The measurement tools and indicators proved, in the case of Croatia, insufficient for clarifying and understanding its progress towards CE. Selection of indicators within monitoring frameworks is arbitrary while their interpretation is highly contextual, dependent on policy targets and local conditions. These results can be extrapolated to other EU member states.Practical implicationsPolicy recommendations for more efficient CE transitions are provided.Originality/valueThis research sheds light on the CE development in Croatia – an understudied European country in this context – and discusses the country's goals towards sustainability. The limited success of developed CE indicators is discussed.

Purpose – The main purpose of this study is to investigate in detail the way each risk is being measured and managed by Islamic banks in the MENA region. Design/methodology/approach – This research attempts to examine the perceptions of Islamic bankers about the importance of transparency and public disclosure in the understanding of the bank's risk profile. It covers 23 Islamic banks located in the MENA region using self-administered questionnaire. Findings – The results show that there are differences in the level of risk perception across funding modes. Also Islamic banks use extensively the traditional tools in mitigating risk. Practical implications – The paper discusses and analyses the current practices employed in the risk management of Islamic banks. It identifies the tools and methods used in managing credit risk, market risk, liquidity risk and operational risk by Islamic banks. Originality/value – This study aims to extend the existing literature in two ways. First, this paper contributes to the dearth of studies on examination of tools practiced in the risk management by Islamic banks located in the MENA region. Next, this work integrates the methods used in the management of liquidity risk that have not been studied earlier.

Purpose – The purpose of this paper is to conduct an empirical analysis among large German companies to enhance the understanding of whether and which institutional factors influence the application of sustainability management tools. Stepping from corporate sustainability visions to implementation requires the application of management tools. A multitude of sustainability management tools have been proposed in literature. Research on their application in corporate practice is, however, scarce. Design/methodology/approach – Based on a survey of large German companies and publicly available data, this paper tests the influence of corporate sustainability networks, indices, standards and the awareness of sustainability management tools on their application in corporate practice. Findings – A particularly strong positive relation exists between awareness and application of sustainability management tools. Standards are also found to have a positive influence, while the influence of networks and indices is less strong. Our findings suggest that the application of sustainability management tools can be fostered through the promotion and increasing awareness of tools. Research limitations/implications – The analysis is based on a survey of large German companies. Factors of institutional isomorphism are tested. Further research is needed for small- and medium-sized enterprises (SMEs) and the influence of further aspects such as competitive and psychological factors. Practical implications – The findings of this paper suggest that the application of sustainability management tools can be fostered particularly well through increasing awareness and the active promotion of tools. Networks, indices and standard help increase awareness. Originality/value – The analysis unveils the role of institutional factors influencing the application sustainability management tools in corporate practice.

Purpose – The purpose of this paper is to analyse the implementation of performance measurement tools by medium-to-large size Italian Local Governments (ILGs) with the aim of establishing their position in comparison with the content of the International Public Sector Accounting Standards Board’s (IPSASB’s) Consultation Paper (CP) on Reporting Service Performance Information and the points of views of other countries. Design/methodology/approach – A survey of all ILGs with more than 50,000 inhabitants has been carried out with the objective of evaluating which kind of performance management tools are implemented; moreover, these results are compared with the content of the IPSASB’s CP to evaluate the role of this guide as well as the main differences between the IPSASB’s approach and the current situation in Italy. Findings – Data collected highlight that several performance measurement tools required by law are generally prepared in ILGs even if a limited use of them for decision-making or accountability purposes occurs. Moreover, in accordance with the opinions of the countries that submitted letters of comment to IPSASB’s CP, Italian results reveal that information on the scope of the service performance information, on the entity’s objectives and their achievement, including a narrative discussion of this achievement, are perceived as relevant. Originality/value – The research investigates the future development of the CP by analyzing the points of view of the countries that submitted letters of comments to IPSASB. It also examines whether the current Italian situation is in line with the IPSASB’s position.

Purpose The purpose of this paper is to examine how deeper psychosocial structures can be examined utilising a contemporary provocative theory within workplace reflection to generate more radical insights and innovation. Design/methodology/approach This paper outlines a provocative theory and then presents case examples of how deeper structures can be examined at the micro, meso and macro levels. Findings Deeper psychosocial structures are the forces that keep the status quo firmly in place, but deeper examination of these structures enable radical insights and therefore the possibility of innovation. Research limitations/implications Deep psychosocial structures shape and constitute daily action, and so work-based and practitioner researchers can be tricked into thinking they have identified new ways of working, but may be demonstrating the same workplace behaviours/outcomes. Workplace behaviours, including emotional responses to apparent change, are key indicators of deeper structures. Practical implications Ideas and processes for examining deeper structures can be integrated into daily reflective practices by individuals, within organisational processes, and wider, system processes. However, because deeper structures can appear in different forms, we can be tricked into reproducing old structures. Social implications Examining deeper structures increases the possibilities for more radical insights into workplace structures, and therefore, how to potentially mobilise innovations which may better serve people and planet. Originality/value This paper is the first to examine the work of Slavoj Žižek in the context of work-based learning.

Purpose – It is clear that libraries consider the use of data to inform decision making a top priority in the next five years. JISC's considerable work on activity data has highlighted the lack of tools and services for libraries to exploit this data. The purpose of this paper is to explore the potential of a shared analytics service for UK academic libraries and introduce the JISC Library Analytics and Metrics Project. The project aims to help libraries effectively management collections and services as well as delivering pre-emptive indicators and “actionable insights” to help identify new trends, personalise services and improve efficiencies, economies and effectiveness (student attainment and satisfaction and institutional reputation, for example). The project builds on the Library Impact Data Project at the University of Huddersfield and the work of the Copac Activity Data and Collections Management tools. The paper will deliver a case study of the project, its progress to date, the challenges of such an approach and the implications the service has for academic libraries. Design/methodology/approach – The paper will be a case study of the project and its institutional partners and early adopters work to date and explore both the technical and cultural challenges of the work as well as its implications for the role of the library within the institution and the services it provides. Specifically the case study will comprise of the following aspects: a brief history of the work and the context of library analytics services in the UK (and internationally). A description of the approach adopted by the project, and the vision and goals of the project. Exploration of the challenges associated with the project. Outline of the implications of the project and the resultant service. Findings – This paper will report on the initial findings of the project, which will run from January to December 2013. In particular it will consider the issues surfaced through the close engagement with the academic library community (through the projects community advisory and planning group) and the institutional early adopters around data gathering and analysis. Practical implications – Data accumulated in one context has the potential to inform decisions and interventions elsewhere. While there are a number of recognised and well-understood use cases for library analytics these tend to revolve around usage and collection management. Yet, the potential of a shared analytics service is in uncovering those links and indicators across diverse data sets. The paper will consider a number of practical impacts: performance – benchmarking, student attainment and research productivity; design – fine tuning services, personalised support; trends – research landscape, student marketplace, utilisation of resources. The case study will explore these practical implications for libraries and what they mean for the future of the library within the academy. Originality/value – The paper will present a case study of a unique service that currently fills an important gap within the library analytics space. The paper will focus on the services potential to transform both the way the library works and how it is perceived by its users, as well as its role and relationship within the broader institution.
