Purpose This paper aims to investigate the environmental impact of various pollutant emissions including carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxide (NOx) and hydrocarbon (HC) from aircraft exhaust gases during the landing and take-off (LTO) cycles at Eskisehir Hasan Polatkan Airport, Turkey, between 2017 and 2018. Design/methodology/approach The methodology approach used to calculate the emissions from aircrafts is based on the ICAO databank and the actual data records taken from Presidency of The Republic of Turkey Directorate of Communications (DoC). Findings The maximum amount of total fuel burnt during the two years is 80.898 and 70.168 tons in 2017 and 2018, respectively, while the average fuel burnt per year from 2017 to 2018 is approximately 369.773 tons. The highest CO, CO2, NOx and HC emissions are found to be 248.3 kg in 2017, 261.380 tons, 1.708 tons and 22.15 kg, during the 2018 year, respectively. Average CO, HC, NOx and CO2 emissions amount per year are observed to be 1.392 tons, 135 kg, 6.909 tons and 1,143 tons, respectively. Considering the average of total emission amount as an environmental factor, as expected, CO2 emissions contributed the most to the total emissions while HC emissions contributed the least to the total emissions from the airport. Practical implications The study presents the approach in determining the amounts of emissions released into the interannual atmosphere and it explicitly provides researchers and policymakers how to follow emissions from commercial aircraft activities at different airports. Originality/value The value of the study lies in the transparent computation of the amounts of pollutants by providing the data directly from the first hand-DoC.

Purpose Subsonic commercial aircraft operate with turbo-fan engines that operate with moderate bypass ratio (BR) co-flowing jets (CFJ). This study aims to analyse CFJ with constant BR 6.3 and varying primary nozzle lip thickness (LT) to find a critical LT in CFJ below which mixing enhances and beyond which mixing inhibits. Design/methodology/approach CFJ were characterized with a constant BR of 6.3 and varying lip thicknesses. A single free jet with a diameter equal to that of a primary nozzle of the co-flowing jet was also studied for comparison. Findings The results show that within a critical limit, the mixing enhanced with an increase in LT. This was signified by a reduction in potential core length (PCL). Beyond this limit, mixing inhibited leading to the elongation of PCL. This limit was controlled by parameters such as LT and magnitude of BR. Practical implications The BR value of CFJ in the present study was 6.3. This lies under the moderate BR value at which subsonic commercial turbofan operates. Hence, it becomes impervious to study its mixing behavior. Originality/value This is the first effort to find the critical value of LT for a constant BR for compressible co-flow jets. The CFJ with moderate BR and varying LT has not been studied in the past. The present study focuses on finding a critical LT below which mixing enhances and above which mixing inhibits.

Purpose The purpose of this paper is to extend understanding regarding the basis and foci of employee commitment. It does so by exploring the direction towards employee centric rather than an assumed organisation basis of commitment. Design/methodology/approach Survey data of over 300 employees from a variety of organisations in the Republic of Ireland were collected. Data focussed on worker orientations and their foci of commitment. Findings The findings confirm a more pluralistic and mixed basis to the antecedents of worker commitment, as opposed to an assumed human resource management unitarist ideology often promoted by organisational managers. At the level of individual workers, a dominant focus for commitment relates to career development and the milieu of an immediate workgroup. Practical implications There are three implications. First, mutual gains possibilities are not straightforward and there are practical pitfalls that employee interests may get squeezed should managerial and customer interests take precedence. Second, there remain competing elements between job security, flexibility and autonomy which can impact performance. Finally, line managers are key conduits shaping commitment and especially psychological contract outcomes. Originality/value This paper unpacks the relationship between ideological orientation and an individual’s foci of commitment. The research found that traditional orientations and foci of commitment are deficient and that simplified individualistic interpretations of the employment relationship are complex and require more critical scrutiny.

Practical Implications

Purpose – The purpose of this paper is to review the development of restorative justice in Ireland since the publication of the Final Report of the National Commission on Restorative Justice in 2009. It argues that although the development of restorative justice in Ireland has progressed slowly, it has also progressed steadily. There are still obstacles in the path of developing a restorative justice framework on a national level for both adult and young offenders, however, all signs indicate that these obstacles can and will be overcome in the future. Design/methodology/approach – The research for this paper was primarily a review of the very limited literature on restorative justice in Ireland. Findings – The development of restorative justice in Ireland has undergone slow and steady progress over the last decade. While a great deal of work is still needed before restorative justice can be rolled out nationally, the progress that has been made suggests that there is a real future for restorative justice in Ireland. Research limitations/implications – Statistics on restorative justice in Ireland are very limited and referral numbers are still lower than what they should be. Practical implications – Any research on restorative justice in Ireland will highlight the fact that more research and analysis is needed, especially in terms of measuring recidivism of offenders who take part in restorative practices. Originality/value – This paper adds to the growing literature on restorative justice in Ireland.

Purpose – The purpose of this paper is to interconnect pedagogy and biology via second-order cybernetics. Design/methodology/approach – The approach taken is that of a synthesis. Findings – Biology can better deal with intersubjectivity within and between species by incorporating approaches and theory from education inquiry. Conversely, educators can de-anthropocentrize their discipline by entering into learning relationships with other species. By rallying around the concept of “eduction”, second-order cybernetics plays a role in both syntheses. Practical implications – De-anthropocentrizing education could have practical value in creating ecologically relevant education for children and in developing more integrated environmental impact assessments. Originality/value – Finding convergence between the study of life and forms of practitioner inquiry in education research, and connecting these to the environmental movement.

Purpose – The purpose of this study is first to describe and discuss an innovative strategy, pursued by a music festival, to reduce the environmental impact by allowing only vegetarian food in the festival area. A second aim is to discuss the effects of the vegetarian strategy for the festival in terms of branding and communication impacts. A third aim is to assess the effect on the ecological footprint of the festival from the vegetarian food strategy. Design/methodology/approach – Festival visitors’ food consumption was surveyed in 2010 (719 responses) and again in 2012 when only vegetarian food was served on festival premises (663 responses). The EPA event calculator, developed in Australia, was used to calculate the ecological footprint of the festival. The implementation and the impacts were studied from the festival organisers’ perspective through two (one hour long) interviews with one of the festival managers. Findings – For the festival brand, the vegetarian strategy proved to be extremely successful in terms of media attention and an enhanced “green” image of the festival. An analysis of the environmental impact of the vegetarian strategy indicates a remarkable drop of 40 per cent in the size of the ecological footprint. Practical implications – Based on the results of this study, a vegetarian strategy can be recommended as an innovation for festivals that have core values and a brand image grounded both in sustainability and the reduction of environmental impacts and that are truly concerned about the environment. Originality/value – Festival Footprint Analysis.

Purpose The purpose of this paper is to understand in-depth how consumers create value in their lives using WhatsApp, the leading mobile instant messaging (MIM) application. Design/methodology/approach The study adopts the perspective of customer-dominant logic (CDL) and uses a qualitative multimethod design involving 3 focus groups and 25 subsequent in-depth interviews. The research setting was Ecuador, a Latin American country. Findings Analysis and interpretation of the participants’ stories made it possible to identify and understand the creation of four types of value: maintaining and strengthening relationships; improving role performance; emotional support; and entertainment and fun. In addition, the present study proposes a conceptual model of consumer value creation as it applies to MIM. Practical implications Understanding the way consumers create value in their lives using MIM is important not only for organizations that offer MIM applications, but also for those companies that develop other applications for mobile phones or for those who wish to use MIM as an electronic word-of-mouth vehicle. Originality/value The current study is one of the first to address the topic of consumer behavior in the use of technologies from the perspective of CDL; this perspective enables an integrated qualitative vision of value creation in which the consumer is the protagonist.

Purpose The purpose of this paper is twofold: first, to understand data management challenges in e-maintenance systems from a holistically viewpoint through summarizing the earlier scattered research in the field, and second, to present a conceptual approach for addressing these challenges in practice. Design/methodology/approach The study is realized as a combination of a literature review and by the means of analyzing the practices on an industry leader in manufacturing and maintenance services. Findings This research provides a general understanding over data management challenges in e-maintenance and summarizes their associated proposed solutions. In addition, this paper lists and exemplifies different types and sources of data which can be collected in e-maintenance, across different organizational levels. Analyzing the data management practices of an e-maintenance industry leader provides a conceptual approach to address identified challenges in practice. Research limitations/implications Since this paper is based on studying the practices of a single company, it might be limited to generalize the results. Future research topics can focus on each of mentioned data management challenges and also validate the applicability of presented model in other companies and industries. Practical implications Understanding the e-maintenance-related challenges helps maintenance managers and other involved stakeholders in e-maintenance systems to better solve the challenges. Originality/value The so-far literature on e-maintenance has been studied with narrow focus to data and data management in e-maintenance appears as one of the less studied topics in the literature. This research paper contributes to e-maintenance by highlighting the deficiencies of the discussion surrounding the perspectives of data management in e-maintenance by studying all common data management challenges and listing different types of data which need to be acquired in e-maintenance systems.

Purpose The purpose of this study is to develop a profile of whistleblowers and to determine whether whistleblowing legislation would encourage those individuals to bring to light some illegal or unethical behaviour that otherwise would remain in the shadows. Design/methodology/approach Having identified whistleblowing correlation, a survey was carried out in Cyprus of actual whistleblowers and could-have-been whistleblowers. Findings Males between 46 and55 years of age, regardless of whether they have dependents or hold senior positions in organizations are significantly more likely to blow the whistle. However, could-have-been whistleblowers did not go ahead because they felt that the authorities would not act on their information. Research limitations/implications Because of the sensitive nature of the research topic and the fact that only whistleblowers or intended whistleblowers could participate in the study, the sample size is limited as a result. This, in turn, limits both the number of respondents in each category (actual and intended) as well as constrains the statistical analysis that could be carried out on the data. Practical implications It remains to be seen whether EU Member States shall implement the European Directive 2019/1937 on the protection of persons who report breaches of Union Law, in its entirety by the due date, namely December 2021. Originality/value This study provides a literature review of whistleblowing and reports an original survey against the backdrop of the European Directive.

Purpose Reviews the latest management developments across the globe and pinpoints practical implications from cutting-edge research and case studies. Design/methodology/approach This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context. Findings The problem with developing a reputation of being something of an oracle in the business world is that all of a sudden, everyone expects you to pull off the trick of interpreting the future on a daily basis. Like a freak show circus act or one-hit wonder pop singer, people expect you to perform when they see you, and they expect you to perform the thing that made you famous, even if it is the one thing in the world you don’t want to do. And when you fail to deliver on these heightened expectations, you are dismissed as a one trick pony, however good that trick is in the first place. Originality/value The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

PurposeThe paper examines how oil multinational companies (MNCs) in Nigeria framed accounts to dissociate themselves from causing oil spills.Design/methodology/approachThe authors utilised data from relevant corporate reports, external accounts and interviews, and used sensegiving with defensive behaviours theoretical framing to explore corporate narratives aimed at altering stakeholders' perceptions.FindingsThe corporations gave sense to their audience by invoking scapegoating blame avoidance narrative in attributing the cause of most oil spills in Nigeria to outsiders (sabotage), despite potentially misclassifying the sabotage-corrosion dichotomy. Corporate stance was reinforced through justifying narrative, which suggested that multi-stakeholders jointly determined the causes of oil spills, thus portraying corporate accounts as transparent, credible and objective.Research limitations/implicationsThe socio-political dynamics in an empirical setting affect corporate accounts and how those accounts appear persuasive, implying that such contextual factors merit consideration when evaluating corporate accounts. For example, despite contradictions in corporate accounts, corporate attribution of oil spills to external factors appeared persuasive due to the inherently complicated socio-political dynamics.Practical implicationsWith compensation to oil spills' victims only legally permitted for non-sabotage-induced spills alongside the burden of proof on the victims, the MNCs are incentivised to attribute most oil spills to sabotage. On policy implication, accountability would be best served when the MNCs are tasked both with the burden of proof and a responsibility to demonstrate their transparency in preventing oil spills, including those caused by sabotage.Originality/valueCrisis situations generate multiple and competing perspectives, but sensegiving and defensive behaviours lenses enrich our understanding of how crisis-ridden companies frame narratives to alter stakeholders' perceptions. Accounts-giving therefore partly satisfies accountability demands, and acts as sensegiving signals aimed at reframing/redefining existing perceptions.
