Abstract
Purpose
The reliable performance of critical components working under extreme conditions is paramount to the safe operation of aircraft, and material selection is critical. Copper alloys are an obvious choice for such applications whenever a combination of transport, mechanical and tribological properties is required. However, low strength and hardness issues require development of new copper alloys and composites to improve service life and reliability. This study aims to investigate the effect of carbon nanotubes as reinforcement phase in copper-matrix composites.
Design/methodology/approach
The development of novel copper-based composites refined to the nanoscale was envisaged through mechanical milling of mixtures containing copper and carbon nanotubes (2 Wt.%). Milling took place in a planetary ball mill for times varying between 1 h and 16 h at 400 rpm. A ball-to-powder ratio of 20:1 and alumina vial and copper spheres were used under dry conditions or with addition of isopropyl alcohol. Scanning electron microscopy/energy dispersive spectroscopy, size distribution, Raman spectroscopy and X-ray diffraction were used to study the produced powders.
Findings
Attained results show that mechanical milling of the studied system produces nanostructured powders containing second-phase carbon nanotubes homogeneously distributed in the metallic matrix, together with severe copper grain refinement. This should correspond to increased residual microstresses, envisaging significant improvement of mechanical properties of the produced copper composites.
Originality/value
The novelty of the work resides in the use of carbon nanotubes for the reinforcement of copper, and on the systematic microstructural characterisation of the produced composites.

Abstract
Purpose
The purpose of this study is to systematically review the recent empirical literature on job stress and burnout among prison staff with a focus on predictors, outcomes of stress and burnout and the mediating role that stress and burnout can play between its predictors and outcomes.
Design/methodology/approach
The authors followed systematic literature review (SLR) protocols for the social sciences, and searches were done on two large research databases: SCOPUS and Web of Science. Articles included in the study were from January 2015 to March 2020. After the screening and eligibility processes, 48 articles met the inclusion/exclusion criteria, and 33 articles were included in the full-text qualitative analysis.
Findings
Characteristics of the samples, main authors and journals and measures used to assess stress and burnout are presented, showing that most research was done in the USA, with cross-sectional studies using similar measures of stress and burnout. Results from the qualitative analysis were organised around the main research questions. Most studies explored the antecedents of stress and burnout in the context of the job demands – resources model. Common predictors that consistently increase stress and burnout among different samples include perceived dangerousness of the job and work–family conflict. Participation in decision-making and social support consistently decrease job stress.
Originality/value
This paper presents a SLR on stress and burnout among prison officers in a pre-COVID-19 pandemic era, providing an important picture of the published scientific research on the topic as well as implications for theory and practice.

Abstract
Purpose
Businesses are increasingly called upon to support the improvement of society and the environment, and one way to do so is by expanding into international markets, particularly through exports. Despite the importance and recognised challenges of a global approach to sustainable value creation, sustainability research tends to focus on domestic contexts. This paper aims to identify the boundary conditions linking sustainable value creation practices with firm performance in the international context.
Design/methodology/approach
The authors merge the sustainable value creation and the international marketing literature to develop two propositions that capture the emerging nature of the field and the lack of concluding evidence regarding the link between international sustainable value creation practices and firm performance. The authors test these propositions empirically by analysing 519 responses to a survey of exporting firms in Portugal, using fuzzy-set qualitative comparative analysis.
Findings
The authors identify seven configurations that support sustainable value creation in an international context. These consist of varying levels of standardised and tailored offers, management experience and competitive intensity.
Practical implications
The identification of seven different configurations helps managers decide whether and how to innovate when pursuing sustainable value creation opportunities in international markets.
Social implications
The authors propose that an effective way for governments to achieve national and transnational social and environmental agendas is to help businesses that pursue sustainable value creation to succeed in international markets. Given that four of the seven pathways to improve export performance that the authors identified require international management experience, the authors posit that an effective way to support the internationalisation of those businesses is through targeted training programmes and knowledge-sharing initiatives.
Originality/value
The authors respond to calls for research to integrate the sustainable value creation and the international marketing literatures, to identify how and when firms can create sustainable value creation in an international context and thus support the resolution of global, social and environmental problems. The finding that there are multiple configurations that support this goal explains why empirical evidence collected thus far is inconclusive and helps identify the boundary conditions of existing theory.

Abstract
Entrepreneurship teachers (ETs) evolve in an environment where different categories of people interact: students, teachers and stakeholders. Assuming one or more identities or roles, teachers, practitioners, ex-entrepreneurs and/or researchers are the ‘transmitters’1 of entrepreneurship education (EE). The question of recognition of teachers’ professional status is not always addressed (Hargreaves, 2000). Scientific research in EE shows certain weaknesses (Byrne, Fayolle, & Toutain, 2014; Fayolle, 2013), notably, a lack of interest in questions of (i) the perceived legitimacy of ETs and (ii) the support they receive in carrying out their work (particularly professional development). Taking a decidedly multidisciplinary perspective, this chapter aims to deal with the question of the perceived legitimacy of ETs using a literature review that covers all disciplines having shown an interest in the notion of teacher legitimacy.
The legitimacy of EE depends on the interactions between legitimate instructors and legitimate students in a given context, which respects certain collectively accepted norms. It also depends on the context and the objective of EE. Following the example of a university hospital worker (doctor), ETs can be practitioners, teachers and researchers. Their degree of expertise, position in the institution, positioning in relation to other actors – students, peers, colleagues, institutional and professional stakeholders – and the discourse they use are the elements that constitute their legitimacy.

Abstract
The background and an overall review of the implementation of the Rio de Janeiro Rapid Transit System – Metro – with its implications in the structure of the transport system within the metropolitan area and in its urban development is provided. Emphasis is given to the social role played by the Metro lines in terms of reducing the travel costs and travelling time of the working population. As such it is also a major political issue which will affect federal and state governments′ priorities and resources allocation.

Abstract
Purpose
The purpose of this paper is to describe the case of the Valorbio research project, in which students of different high-level programs were involved in the experimental work and in the dissemination of results in collaboration with the research team.
Design/methodology/approach
The inclusion in higher education curricula of content related to the sustainable development should be a preferred mechanism for the dissemination of good practices of sustainability. Another equally important way to achieve this is to involve students in research projects that seek solutions to the societal challenges related to sustainable growth. The Valorbio project aims to meet the needs for treating and reusing wastewater and solid waste. Its main goal was the development of modular systems for wastewater treatment based on constructed wetlands, exploring the possibility of the treatment systems being composed of solid waste and by-products from significant industrial sectors.
Findings
The students’ contribution to the research work was relevant and simultaneously allowed them to acquire skills on sustainable development. Additionally, the students contributed to the dissemination of the results. The Valorbio project can thus be considered a successful application of the concept of project-based learning (PBL), as a way to include sustainability issues content in the higher education curricula.
Originality/value
The applied experimental work had an original approach regarding the equipment design, the waste materials valuation, as well as the integration of waste treatment processes in the circular economy paradigm. This paper is the first reported PBL experience involving students of short-cycle technical–professional programs in partnership with first and second-level students and a research team.

Abstract
We present a critical literature review debating Brazilian research on social and environmental accounting (SEA). The aim of this study is to understand the role of politics in the construction of hegemonies in SEA research in Brazil. In particular, we examine the role of hegemony in relation to the co-option of SEA literature and sustainability in the Brazilian context by the logic of development for economic growth in emerging economies. The methodological approach adopts a post-structural perspective that reflects Laclau and Mouffe’s discourse theory. The study employs a hermeneutical, rhetorical approach to understand and classify 352 Brazilian research articles on SEA. We employ Brown and Fraser’s (2006) categorizations of SEA literature to help in our analysis: the business case, the stakeholder–accountability approach, and the critical case. We argue that the business case is prominent in Brazilian studies. Second-stage analysis suggests that the major themes under discussion include measurement, consulting, and descriptive approach. We argue that these themes illustrate the degree of influence of the hegemonic politics relevant to emerging economics, as these themes predominantly concern economic growth and a capitalist context. This paper discusses trends and practices in the Brazilian literature on SEA and argues that the focus means that SEA avoids critical debates of the role of capitalist logics in an emerging economy concerning sustainability. We urge the Brazilian academy to understand the implications of its reifying agenda and engage, counter-hegemonically, in a social and political agenda beyond the hegemonic support of a particular set of capitalist interests.

Abstract
Purpose
This paper aims to discuss the contribution of knowing in practice (KP) to the development of dynamic capabilities (DC) in the context of health-care organizations.
Design/methodology/approach
The authors develop a case study in a Brazilian hospital in three stages using the data collection techniques of interviews, focus groups, shadowing and conjoint analysis. The participants were health-care employees, supervisors, project managers and members of the board of directors.
Findings
This paper identifies the contribution of KP to develop DC based on strategic practices and their respective microprocesses as key elements to DC microfoundations. In the end, the paper points out a mutual contribution between the theoretical approaches.
Research limitations/implications
This proposal makes sense in organizations where the practices have a strategic nature, such as hospitals and service providers.
Practical implications
This study suggests an alignment between strategic and operational views, stimulating learning across organizational levels.
Originality/value
KP helps to give DC a tangible form by including a human dimension into microfoundations, giving voice to practitioners in the strategic decisions. The integration of KP and DC approaches allows organizations to perceive DC in daily practices making DC present in every organizational level, stimulating a continuous organizational learning process.
