Abstract
Purpose
This paper seeks to understand children’s responses to food waste in school by exploring children’s views on food waste and empowering them to discuss and develop their own solutions.
Design/methodology/approach
Using creative problem-solving approach and photovoice technique, the authors conducted focus group discussions with 28 primary school children in the UK.
Findings
Children have a clear understanding of the consequences of food waste for individuals, society and the environment. They displayed negative emotions concerning food waste and responded positively to the possibility of food recycling. Their solutions to reduce food waste will require multiple stakeholder engagement, including self-regulation, peer-monitoring, teacher supervision and family support. However, rather than relying on intervention schemes that require significant adult involvement, children placed a heavy emphasis on self-regulation, playing an active role in addressing food waste in school.
Originality/value
This research extends previous understanding, by showing children as agentic consumers who can shape food waste solutions in school. These findings are of use to primary teachers and local education authorities, to aid children in developing their own solutions to reduce food waste in their own schools.

Abstract
Purpose
The purpose of this study is to provide the description of a computational methodology to model the combined propulsive systems of hydrogen propelled air-breathing scramjet vehicles and to evaluate the pollutant and climate-changing emissions.
Design/methodology/approach
Emissions indexes of nitrogen oxide (EINO) and water vapour released by the air turbo rocket (ATR) and dual mode ramjet (DMR) engines of the STRATOFLY air-breathing, hypersonic scramjet vehicle, propelled by hydrogen/air were evaluated. ATR engine operation was assessed for several cruise conditions in both subsonic and supersonic flight regimes in Ecosimpro software, which is an object-oriented thermodynamic design and simulation platform. ATR combustor inlet flow conditions play a key role in the computation of species mass fractions, and these conditions are highly dependent on turbomachinery performance and engine flight regime. A propulsive operational database was created by varying mass flow rates of fuel and flight conditions such as cruise speed and altitude to investigate possible engine operations. The all-inlet conditions in this map are provided to the Cantera-Python chemical/combustion chemistry solver implementing a specially designed and formulated 0D kinetic-thermodynamic methodology successfully used to model and simulate the electric spark ignition required to activate the combustion process of the reacting mixture in the ATR combustion chambers, whereas the coupled aero-thermodynamic/aero-propulsive 0D/1D code i.e. Scramjet PREliminary Aerothermodynamic Design (SPREAD), designed and developed by the Italian Aerospace Research Centre (CIRA) was used for DMR calculations. Results show low emissions of NO according to the optimized design of the ATR; on the other hand, a tuning of operational conditions is needed for DMR, with its complete re-design to be more conclusive. Analogously, the released amount of water vapour is in good agreement with the required combustion efficiency and the expected propulsive performance.

Abstract
Purpose
With an extensive range of information available at the swipe of a finger, the smartphone has become a ubiquitous tool for augmenting conversation. Users of English as a lingua franca (ELF) often rely on such technology to help establish friendships by using them to sustain intersubjectivity. But how do they manage the multiple involvements this entails, such as participating in current talk while searching for linguistic items?
Methodology/approach
This study employs multimodal Conversation Analysis to undertake a detailed account of the way two young people, a Japanese male (22) and an Indonesian male (16) incorporate smartphones into their lingua franca English interaction. The analysis is based on naturally occurring conversations video-recorded by the Japanese participant, while both boys were living with an American homestay family.
Findings
The analysis explores the role of the smartphone in forward-oriented repair, including how the interactants, look up unfamiliar words, delay turn progressivity to fit those words into the turn-in-progress, and use images to accompany an unclear term. Speakers also occasionally abandon a look-up in order to reformulate the turn without the smartphone, relying instead on their own interactional competence.
Originality/value
The study offers insight into the way young people use smartphones as an affordance to manage and repair aspects of their L2 talk, enabling them to enhance their current interactional competence by drawing on the vast range of semiotic resources the phone possesses. Ensuring understanding is essential for developing and maintaining friendships, and for this particular peer culture of lingua franca English speakers, smartphones are a key tool for accomplishing that. As such, the study will be of interest to researchers and educators in the fields of both technology and interaction.

Abstract
Purpose
This paper aims to present an account and discussion of Imam Ali’s view on poverty and socio-economic justice. The concept of socio-economic justice is of utmost importance in Islamic teachings.
Design/methodology/approach
This exercise is based on examining Nahj al-Balagha, a tenth century collection of sermons and letters of Imam Ali Ibn Abutalib.
Findings
First, in Imam Ali’s view, socially just outcomes can only be achieved through just means and procedures. Second, acute and visible inequalities and side-by-side co-existence of extreme wealth and poverty in a society point to the existence of socio-economic injustices. Third, a society that is suffering from severe and continuous socio-economic injustices or, in other words, acute poverty and inequality will cease to prosper and develop. Fourth, the main objective of an Islamic governance system is to adopt policies, institutions and procedures that would reduce or eliminate socio-economic injustices. A government that fails to reduce socio-economic injustices, in Imam Ali’s view, has failed in its main mission of protecting the rights of the public and ensuring their prosperity. Finally, regardless of government action or inaction, each individual in a society is also responsible to reduce socio-economic injustices to the best of his/her knowledge and ability.
Originality/value
This paper aims to present the first comprehensive account of Imam Ali’s view on poverty and socio-economic justice and it could prove to be practically useful to modern Muslims and non-Muslims alike, whatever their position in society.

Abstract
Purpose
Effective information security management (ISM) contributes to building a healthy organizational digital ecology. However, few studies have built an analysis framework for critical influencing factors to discuss the combined influence mechanism of multiple factors on ISM performance (ISMP). This study aims to explore the critical success factors and understand how these factors contribute to ISMP.
Design/methodology/approach
This study used a mixed-method approach to achieve this study’s research goals. In Study 1, the authors conducted a qualitative analysis to take a series of International Organization for Standardization/International Electrotechnical Commission standard documents as the basis to refine the critical factors that may influence organizations’ ISMP. In Study 2, the authors built a research model based on the organizational control perspective and used the survey-based partial least squares-based structural equation modeling (PLS-SEM) approach to understand the relationships between these factors in promoting ISMP. In Study 3, the authors used the fuzzy set qualitative comparative analysis (fsQCA) method to empirically analyze the complex mechanisms of how the combinations of the factors affect ISMP.
Findings
The following three research findings are obtained. First, based on the text-based qualitative analysis, the authors refined the critical success factors that may increase ISMP, including information security policies (ISP), top management support (TMS), alignment (ALI), information security risk assessment (IRA), information security awareness (ISA) and information security culture (ISC). Second, the PLS-SEM testing results confirmed TMS is the antecedent variable motivating organization’s formation (ISP) and information control (ISC) approaches; these two types of organization control approaches increase IRA, ISA and ALI and then promote ISMP directly and indirectly. Third, the fsQCA testing results found two configurations that can achieve high ISMP and one driving path that leads to non-high ISMP.
Originality/value
This study extends knowledge by exploring configuration factors to improve or impede the performances of organizations’ ISM. To the best of the authors’ knowledge, this study is one of the first to explore the use of the fsQCA approach in information security studies, and the results not only revealed causal associations between single factors but also highlighted the critical role of configuration factors in developing organizational ISMP. This study calls attention to information security managers of an organization should highlight the combined effect between the factors and reasonably allocate organizational resources to achieve high ISMP.

Abstract
Purpose
Based on the significance of context, the purpose of this paper is to investigate a positive top management team (TMT) gender diversity–productivity relationship derived from the upper echelons theory, and a moderating effect of board gender diversity on the TMT gender diversity–productivity relationship derived from the relational framework.
Design/methodology/approach
The hypotheses were tested in 172 organisations listed on the Australian Securities Exchange. This research uses archival data from multiple secondary sources, with a one-year time lag between the predictor and outcome.
Findings
The findings indicate a positive effect of TMT gender diversity on employee productivity and a strong positive TMT gender diversity–employee productivity relationship in organisations with a low level of board gender diversity.
Originality/value
This study provides pioneering evidence for a positive effect of TMT gender diversity on employee productivity and for a moderating effect of board gender diversity.

Abstract
Purpose
The aim of this study is to employ the failure mode and effect analysis (FMEA) for risk management in cross-country pipelines, coupled with the utilization of Geographic Information System (GIS). The objective is to enhance the significance of the project, considering the potential severe consequences of pipeline failures. These consequences encompass environmental damages, loss of life and disruptions to critical services like energy and water supply. By identifying the most frequent causes of pipeline failures and developing a predictive model, the intention is to contribute toward the prevention of such incidents and minimize their impact.
Design/methodology/approach
A total quality management (TQM) technique for risk management; FMEA, was employed in this study integrated with GIS. Eight specific failures were identified and analyzed, exploring their effects and severity, causes and likelihood of occurrence as well as control and detection value. To find the likelihood of occurrence along the pipeline, the GIS was utilized to survey a 10 km wide area along the pipeline of 180 km long. Occurrence spatial mapping for each individual failure was generated. Subsequently, the risk priority number (RPN) was calculated for each failure, presenting the values as separate maps. By overlaying the RPN maps, a final map was generated, illustrating the areas with the highest risk along the pipeline.
Findings
A modified risk management model has been developed to detect potential pipeline failures before they escalate into catastrophic events. The results provide a visual representation of the average failure modes along the pipeline, clearly highlighting regions with varying probabilities of failure based on RPN values. The RPN has been meticulously calculated across the entire pipeline, with results presented through both 2D spatial mapping and a comprehensive line graph. This comprehensive approach sets our study apart from others in the field. Our emphasis on a thorough and inclusive risk assessment methodology represents a key novelty in this research. The findings underscore the paramount importance of proactive maintenance and regular inspection practices, with these measures emerging as critical strategies for enhancing the reliability and safety of pipeline infrastructure.
Research limitations/implications
This research study aims to enhance the safety and quality of cross-country pipelines. The main limitations of the study include the inability to consider the risks associated with the flow characteristics inside the pipeline and the exclusion of the future master plan from our analysis.
Practical implications
The current integrated model is significant for pipeline operative companies and the oil and gas industries. These pipelines are susceptible to failures that can have alarming negative impacts on the environment, human safety and public health. It can improve the quality of risk management and elevate the safety integrity level of their pipelines. Focusing on the high-risk areas, taking action and implementing proactive measures can reduce the risk of failure and improve the safety and reliability of the pipeline system. It utilizes GIS-detailed surveying of the areas along the pipeline without the necessity of making on-site visits.
Originality/value
This study introduces a novel framework incorporating FMEA for quality risk management with advanced spatial mapping GIS software. This approach stands out as a unique contribution to the field, as prior studies have not undertaken the comprehensive task of highlighting risks along the entire pipeline using such a sophisticated methodology. This research makes a significant contribution to the field of crude oil transportation through pipelines, ultimately mitigating the risk of undesirable events.

Abstract
Purpose
The purpose of this paper is to show how unaccompanied minors perceive the time they spend in transitional houses in Malmö in southern Sweden. An important outlook when presenting the empiric data is to provide the perspective of the child, not just to have a child perspective (i.e. an adult perspective on children's experiences).
Design/methodology/approach
The paper is the result of interviews with 11 unaccompanied boys living in transitional houses, i.e., group homes. The theoretical section has two purposes, to describe the Swedish context and the ambivalent discourse regarding immigrants in Sweden and to give a background on aspects that are relevant to understand unaccompanied minors situation.
Findings
Even though many unaccompanied minors suffer from psychological difficulties and worries about the asylum process, the interviews show that the children in this study are generally content with the transitional houses. The staff strives to support them in coping with daily life, and strengthen their sense of coherence.
Research limitations/implications
Since unaccompanied minors do not have family close by, the interviews shows the importance in different sorts of activities to promote wellbeing. A stronger focus on participation could also be a way of reinforcing the children's sense of coherence.
Originality/value
This paper gives an insight to life in transitional houses from unaccompanied minors point of view.
