Purpose – This research investigated the feasibility of using an inductively coupled antenna as the basis of applying a systems approach to smart clothing. In order to simulate real-life situations, the impact of the distortions and relative displacement of different fabric layers (with affixed antennas) on the signal quality was assessed. The paper aims to discuss these issues. Design/methodology/approach – A spiral antenna was printed on different fabric substrates. Obstructive conditions of the inductively coupled fabric layers were investigated to find out how much influence these conditions had on transmission performance. Reflected signals and transmitted signals were observed, while fabric antennas were subjected to displacement (distance and dislocation) or deformation (stretching and bending). The threshold of physical obstacles was estimated based on statistical analyses. Findings – The limits of physical conditions that enable proper wireless transmission were estimated up to ∼2 cm for both distance and dislocation, and ∼0.24 K for bending deformation. The antenna performance remained within an acceptable level of 20 percent transmission up to 10 percent fabric stretch. Based on well-established performance metrics used in clothing environment on the body, which employs 2-5 cm of ease, the results imply that the inductively coupled antennas may be suitable for use in smart clothing. Originality/value – This research demonstrates that the use of inductively coupled antennas on multiple clothing layers could offer the basis of a new “wireless” system approach to smart clothing. This would not only result in performance benefits, but would also significantly improve the aesthetics of smart clothing which should result in new markets for such products.

The Impact

Purpose The purpose of this paper is twofold. First, it discusses the role of entrepreneurship, in general, and women entrepreneurship, in particular, in advancing the cause of sustainable development. Future research directions that emerge from the body of knowledge that the paper relied upon have been identified. Second, it presents unique cases of eight women-led enterprises in energy sector spread across three continents, namely, Asia, Africa and the USA; identifies the constraints and opportunities, analyses the business models and their impact on the quality of life pointers to demonstrate the role of women-led enterprises in sustainable development. Design/methodology/approach The paper combines a schematic review of literature at the interface of entrepreneurship and sustainable development coupled with select relevant case studies addressing the interface. The real-life case studies, which are consciously chosen and compiled from secondary data sources, complement and testify the insights drawn from the schematic literature review. The framework for analyzing the case studies is designed around multidimensional drivers and factors that steer the women-led enterprises. Findings The paper identified the need to look at entrepreneurship through the gendered lens not only for studying entrepreneurship as a discipline, in general, but also to gauge whether the inclusion of women as entrepreneurs is actually advancing the cause of sustainable development. Besides analyzing real-life case studies of accomplished women entrepreneurs to gauge their motivations and mindsets, the process of identification of pain points, identifying differentiating and innovative features, or studying the impact on society, economy and environment, the paper eventually created a schematic framework of key enablers, constraints and strategic response of women entrepreneurs. Originality/value Given the dearth of adequate theoretical and empirical contributions on the study of effectuation, mindsets and drivers of how women entrepreneurship steers the process of sustainable development, the paper is an endeavour in that direction.

Purpose – The aim of this study is to examine the impact of the psychological contract, relational psychological contract and transactional psychological contract on organisational commitment as mediated by transactional leadership in the United Arab Emirates (UAE) context. The paper also explores the contractual status to determine if the theory remains valid, regardless of the fact whether one is employed as a contingent or permanent worker. Design/methodology/approach – This research made a longitudinal study spanning a 24-week time period. Data were collected using a self-administered structured questionnaire prepared in English and Arabic, at three stages representing three visits to the participating companies in the UAE. Pearson’s correlation analysis and multiple regression analysis were used to examine the research hypotheses. Findings – The results show that the psychological contracts (transactional and relational) are positively related to transactional leadership. This study categorizes several consequential relationships between transactional leadership and organisational commitment. It also advocates that transactional leadership has only a fractional mediating role in relation to relational psychological contract, transactional psychological contract and organisational commitment. Practical implications – The findings suggest that practitioners and academics alike should note that the nature of the psychological contract employed will impact upon commitment and retention. Originality/value – This study makes a significant contribution to the body of literature, being the second part of a longitudinal study that aimed at testing the mediating effect of transactional leadership on organisational commitment within the context of the UAE. In the earlier study, the intent was to analyse the role of transformational leadership as a mediator between the psychological contract and organisational commitment. Typically, transformational leadership has been found to partially mediate the above mentioned relationships. In addition, it also advocates that there may be some value in considering the employees’ contractual status with regard to the psychological contract and its impact on organisational commitment.

Purpose “Co-production” is a process in health and social care wherein service users and practitioners work in partnership. Recovery colleges (RCs) are educational establishments offering mental health education; a cornerstone feature is that courses are designed and delivered in parity by both mental health practitioners and “peers” – people with lived experience of mental illness. This paper aims to consider, through the identification of key themes, whether co-production within RCs is operating successfully. Design/methodology/approach The paper is a systematic review of qualitative literature. Relevant concept groups were systematically searched using three bibliographic databases: Medline, Social Care Online and Scopus. Articles were quality appraised and then synthesised through inductive thematic analysis and emergent trends identified. Findings Synthesis identified three key themes relating to the impact of co-production in RCs: practitioner attitudes, power dynamics between practitioners and service users, and RCs’ relationships with their host organisations. As a result of RC engagement, traditional practitioner/patient hierarchies were found to be eroding. Practitioners felt they were more person-centred. RCs can model good co-productive practices to their host organisations. The review concluded, with some caveats, that RC co-production was of high fidelity. Originality/value RC research is growing, but the body of evidence remains relatively small. Most of what exists examine the impact of RCs on individuals’ overall recovery and mental health; there is a limited empirical investigation into whether their flagship feature of parity between peers and practitioners is genuine.

PurposeThis study investigates the impact of agri-food supply chains (AFSCs) characteristics on the antecedents of horizontal logistics collaboration (HLC). Specifically, the study compares the relationship between collaboration activities and outcomes for companies in and outside AFSCs.Design/methodology/approachFirst, a survey was used to collect data from different industries. Second, confirmatory factor analysis and structural equation modeling were applied to compare the measurement and structural models from different industry categories.FindingsThe results support the premise that collaboration improves trust and commitment in the relationship, which in turn enhance satisfaction. The results also show the existence of a minor influence of AFSCs characteristics on HLC antecedents, in the form of an indirect impact of dedicated investments on commitment.Practical implicationsThe factors having a significant influence on the collaboration outcomes and their respective effects are generally similar across food and nonfood supply chains, providing opportunities for interdisciplinary and collaboration experiences.Originality/valueThis research contributes to the body of knowledge on interfirm collaboration by considering the specificities of HLC. It also highlights the importance of conducting contingency research on collaborative experiences, as firms from different industry contexts operate under distinct operational conditions.

Purpose The purpose of this paper is to measure the impact of open government data (OGD) on citizen empowerment. Design/methodology/approach This study advances the body of knowledge on OGD by proposing an integrated research model based on transparency, accountability, participation and collaboration dimensions. The research model was empirically tested using 275 responses using the on-paper survey from the university students and professionals in Bangladesh. Data were analyzed using the structured equation modeling technique. Findings Findings revealed that transparency and participation have a positive and significant direct and indirect influence on citizen empowerment through accountability and collaboration. Overall, the four basic pillars of OGD such as transparency, participation, accountability and collaboration interrelated with each other and have the impact on citizen empowerment. Research limitations/implications This study has proposed an instrument that sums the dimensions of open government, which avoids tautology and redundancy among OGD dimensions. More research should be done to validate the proposed model and the instruments used in this study. Practical implications For the researchers, this study provides a basis for further refinement of individual models of empowerment. For practitioners, understanding the key constructs is crucial to design, refine and implement OGD systems and applications that empower citizens, create public values and strengthen the democratic process. Originality/value This research is the first step that empirically investigates the impact of OGD on citizen empowerment which is the ultimate goals of any democratic government.

The Impact

Purpose – The purpose of this paper is to present a yardstick efficiency comparison of 269 Indonesian municipal water utilities (MWUs) and measures the impact of exogenous environmental variables on efficiency scores. Design/methodology/approach – Two-stage Stackelberg leader-follower data envelopment analysis (DEA) and artificial neural networks (ANN) were employed. Findings – Given that serviceability was treated as the leader and profitability as the follower, the first and second stage DEA scores were 55 and 32 percent (0 percent = totally inefficient, 100 percent = perfectly efficient), respectively. This indicates sizeable opportunities for improvement, with 39 percent of the total sample facing serious problems in both first- and second-stage efficiencies. When profitability instead leads serviceability, this results in more decreased efficiency. The size of the population served was the most important exogenous environmental variable affecting DEA efficiency scores in both the first and second stages. Research limitations/implications – The present study was limited by the overly restrictive assumption that all MWUs operate at a constant-return-to-scale. Practical implications – These research findings will enable better management of the MWUs in question, allowing their current level of performance to be objectively compared with that of their peers, both in terms of scale and area of operation. These findings will also help the government prioritize assistance measures for MWUs that are suffering from acute performance gaps, and to devise a strategic national plan to revitalize Indonesia’s water sector. Originality/value – This paper enriches the body of knowledge by filling in knowledge gaps relating to benchmarking in Indonesia’s water industry, as well as in the application of ensemble two-stage DEA and ANN, which are still rare in the literature.

PurposeThis paper aims at providing an overview and synthesis of the existing body of knowledge about greenwashing. Special attention is paid to the articles directly linked with agriculture, food industry and food retail.Design/methodology/approachA bibliometric analysis was performed over 351 documents extracted from the WoS database, using SciMAT and VOSviewer software programs.FindingsThree periods in the academic literature about greenwashing can be distinguished: ground-setting (2003–2010), trail-blazing (2011–2015) and remarkable growth (2016–2020). Along this evolution, a body of knowledge which stemmed from the literature about CSR has achieved a major development, deploying different research lines such as stakeholders' management, marketing and communication and audit. A specific analysis of the academic literature about greenwashing in agriculture, food industry and food retail has been carried out, showing a need for further development.Social implicationsThe development of scientific knowledge about greenwashing puts this social claim on the spotlight of business management studies, helping to fight greenwashing and, this way, to reduce the environmental impact of corporate activities. Studying greenwashing will help to reduce its frequency and, therefore, heal the planet.Originality/valueSome previous studies have provided systematic reviews of the literature using different approaches, but they did not untangle the intellectual structure and the evolution of the body of research about greenwashing. This article originally provides a thorough analysis of these aspects, as well as a closer look at the impact of greenwashing practices in the academic literature regarding agriculture, food industry and food retail.

Purpose This paper aims to discuss how educators can teach sustainability-oriented capabilities (SOCs) using an active learning approach. Design/methodology/approach Using a case study methodology centered on a Brazilian business school, this research combines qualitative analysis of content, such as teacher notes and student work, with quantitative analysis of student grades. The authors used variance analysis and Bonferroni tests to establish whether the means of three test groups were significantly different. The authors also tested for normality, using the Skewness Kurtosis test, and for homoscedasticity, using Levene. Findings The authors’ findings suggest that the active learning (AL) method may be useful in developing SOCs related to the capabilities of “to know,” “to do,” “to interact” and “to be” because it improved student engagement in the program. In addition, this improved engagement was shown to have a positive influence on grades. Research limitations/implications Using convenience sampling, the authors studied a limited number of the mandatory management courses offered by Insper. There is a need to check for nonlinear positive effects over a more extended period of time and considering more courses. Practical implications This paper offers a practical and replicable technique for teaching SOCs in a business school context using AL. Originality/value The existing literature on education and sustainability discusses the role of business schools in the development of SOCs, especially with respect to curricular changes that integrate content and frameworks related to the conceptualization of sustainable development for business (Cebrián and Junyent, 2015; Cortese, 2003; Fairfield, 2018; Aleixo et al., 2020; Leal Filho, 2020; Arruda Filho et al., 2019). However, some studies suggest that the learning process at many business schools fails to explore the complexity of real life by not using a teaching approach that favors the development of SOCs (Leal Filho et al., 2015). Thus, prior studies have pointed to the need for further research on the impact of the active learning approach in teaching about sustainability (Leal Filho et al., 2015; Fisher and Bonn, 2011; Hesselbarth and Schaltegger, 2014). The aim of this research is to contribute to this discussion.
