Abstract
A sheet metal forming simulation code has been developed, based on the explicit time integration scheme and Mindlin shell theory. It has been used for the analysis of a number of industrial parts. After recalling some modelling issues, this paper describes an industrial methodology based on the experience of those analyses. The aim of the methodology is to provide, at early design stage, information on the product formability with a workload and lead time adapted to the design delays. Concurrently 2D analyses, critical zones studies and coarse mesh global investigations can be used, with a flexible number of iterations, prior to full refined analyses of the forming process. The application of the methodology on several industrial examples is discussed.

Abstract
Purpose
The purpose of this paper is to evaluate the physicochemical properties, fatty acids, tocopherols, and polyphenols of Algerian argan oil.
Design/methodology/approach
The argan oil was extracted from the kernel by an organic solvent, the n‐hexane. Several methods and techniques (spectrophotometric, titrimetric, refractometric, and chomrtographic (CPG/high‐performance liquid chromatographic – HPLC) were used to characterise to argan oil.
Findings
The argan oil was yellow oil with faintly marked smell and flavour. The physicochemical analysis showed that the oil was pure, fresh, not siccative and rich in C18 medium chain unsaturated fatty acids, particularly the oleic acid. A HPLC and gaseous phase chromatography methods were developed for the quali‐quantitative analysis of α‐tocopherol and fatty acids composition, respectively.
Research limitations/implications
This highlight shows that the composition of argan oil is oleic‐linoleic type rich in α‐tocopherol (20 mg/kg). The phenolic fraction known for its antioxidant properties ranges from 30 to 50 mg/kg. The argan oil is mainly rich in antioxidant compounds such as phenolic compounds and α‐tocopherol. Argan oil is rich in unsaturated fatty acids, tocopherol and phenolic compounds.
Practical implications
Considering its rich composition in antioxidant compounds and essential fatty acid, argan oil has been used for a long time as a food and for body care, prevention and treatment of cardiovascular and some cancers diseases. A deep knowledge of the chemical composition of argan oil will certainly show that is has a high‐nutritional potentiality and is claimed to have favourable medicinal and cosmetic properties.
Originality/value
No such research has been carried out on the argan oil extracted from Argania spinosa (L.) of Algeria. The present work was undertaken to study the physicochemical and nutritional properties of the argan oil.

Abstract
Purpose
Academics recently identified a lack of research regarding who should guide interactions in virtual social networks when risks appear. Data shows that organizers are usually less active than other users in this context, which can lead to negative reactions among attendees. This research examines if and how virtual social network communication guided by an official source (vs a nonofficial source vs control group) reduces perceived crime risks and trust before the event, leading to lower ambivalence and higher intention to attend. The study was conducted in Colombia, a country where many individuals face this type of risk.
Design/methodology/approach
First-year university students (N = 210) from Colombia were invited to a “Welcome Cocktail”. Two weeks before the cocktail, they were divided into three groups (70 per condition) to receive information. In Group 1, participants were invited to be part of a WhatsApp group administered by one of the organizers. In Group 2, they participated in a WhatsApp group administered by a student. Group 3 was the control (i.e. no virtual communication established before the event). One week after the meeting, they were gathered again and answered a questionnaire, which measured perceived crime risk, trust, ambivalence and intention to attend.
Findings
Participants in the WhatsApp group administered by an official source perceived lower risk and higher trust in the organizers, which led to lower ambivalence towards the event and higher intention to attend it. The relationship between ambivalence and intention to attend is moderated by the nationality of the participants (locals vs foreigners), such as, at equal levels of ambivalence, foreigners show lower intention to attend the event.
Originality/value
This is the first study that compares different approaches on a virtual social network to reduce perceived crime risk in event management. The results present new findings on how the presence of an official source can mitigate this risk, and which potential attendees (i.e. locals vs foreigners) are especially benefited from it. The findings are particularly useful for managers in regions where attendees face crime risks every day, and might feel low trust towards public and private institutions, such as in Colombia.

Abstract
Purpose
The main objective of this article is to visualize the structure and trends of pro-environmental behavior (PEB) between 1999 and 2023 through mapping and in-depth analysis. The aim is to analyze PEB, which has received considerable academic attention in recent years due to its key role in the conservation of the environment and the protection of local communities in tourist destinations. This paper provides an important summary of the recent research that has explored the role that tourists have in protecting the environment through PEB.
Design/methodology/approach
This study presents a visual analysis of 2005 scholarly articles between the years 1999 and 2023 related to PEB. Using the knowledge mapping based on VOSviewer it presents the current status of research, which includes the analysis of citation analysis, co-citation analysis, co-citation network and longitudinal analysis.
Findings
PEB is an emerging topic due to its relevance to protecting the environment in the context of travel. The citation and co-citation analysis show the relevance of the behavior of tourists with regard to protecting the environment. The co-word analysis highlights the current significance of research concerning green hotels and the destination image of environmentally responsible destinations.
Originality/value
This study sheds light on the current research progress of PEB in the context of tourism through a comprehensive analysis (citation, co-citation and co-word). In addition, we provide theories and factors that have been previously used to study PEB in the context of tourism. The findings contribute to a broad and diverse understanding of the concept of PEB, which can provide important insights for policymakers in formulating management strategies and policies aimed at reducing environmental impacts in destinations.

Abstract
This paper reviews Tunisia's movement to an agricultural export strategy as a method of creating rural economic growth. Having explained the economic logic and pitfalls of agro-export production, it then evaluates the Tunisian effort to develop an agricultural export industry first in general and then using a specific case study of strawberry adoption in Cap Bon. Results show that Tunisia has been successful in increasing agro-export production, though as yet not in using it to create equitable rural growth.

Abstract
Purpose
This study intends to explore whether green transformational leadership is effective in promoting employee green performance. What role do moral reflectiveness and green crafting play in the impact of green transformational leadership on employee green performance?
Design/methodology/approach
This study collected research data from a series of questionnaire surveys using a multisource and time-lagged design. We collected 582 completed questionnaires from 97 groups in chemical firms.
Findings
The analysis showed that (1) green transformational leadership positively affected employee green performance and (2) moral reflectiveness and green crafting sequentially mediated the relationship between green transformational leadership and employees’ green performance.
Originality/value
The 2-1-1 multilevel mediation model clarified how the perspectives of leaders and employees are associated, confirming that green transformational leadership successfully promotes the green performance of subordinates through value communication and resource provision. Chemical companies need green transformational leaders passionate about environmental issues to encourage employee engagement in sustainability initiatives, ultimately enhancing employees’ green performance and achieving sustainable development of the chemical organization.

Abstract
Purpose
The paper aims to explore and explain sustainable behaviours in an organizational context using self-determination theory, suggesting that individuals are likely to be engaged in green practices when supported by their needs.
Design/methodology/approach
The study used three waves of longitudinal design, consisting of 702 executives in leadership roles across public and private companies with an average of 15–20 years of work experience. Professionals working throughout PAN India, the USA, Germany and Australia provided us with the data.
Findings
Green transformational leaderships play a pivot in fostering optimism in employees when recrafting their work. Employees being encouraged to evaluate their jobs within the organization’s capacity would bring meaningful change and envision a sustainable future. All the study hypotheses were supported, highlighting the importance of green-focused leadership with individual agencies in line with the organization’s green values.
Practical implications
Using sustainable practices advances organizations in providing green commitment through leadership. Implementing this in the organization can help achieve long-term success by ensuring sustainable practices are embedded in culture rather than a peripheral initiative promoting sustainable decision-making and behaviours.
Originality/value
The study provides insights into the factors influencing decisions to maintain and adopt sustainable practices by providing a deeper understanding of green behaviour change and strategies for promoting pro-environmental strategies in organizations.

Abstract
Purpose
This study sought to examine the effect of green transformational leadership (GTL) on financial performance (FPef) of star-rated hotels in Addis Ababa and also delving into the mediating effect of environmental management practices (EMPs) on GTL–FPef nexus.
Design/methodology/approach
The study used survey data, and analysis was done using SPSS 25, AMOS 24 and PROCESS Macro to determine the mediating effect of EMPs on the GTL–FPef nexus in hotel sector (n = 100).
Findings
The study found that the hotels under investigation have little access to green financing, lack environmental policy and strategy, perceived low stakeholders’ pressure to embrace eco-friendly practices and implemented EMPs to a lesser extent. Regression results demonstrated that GTL had a positive effect on EMPs and FPef. Furthermore, the result of a mediation test conducted using SPSS PROCESS macro revealed that the relationship between GTL and FPef is partially mediated by EMPs. Finally, one-way ANOVA result revealed that luxury hotels adopt EMPs better than budget hotels.
Practical implications
This study provides valuable practical insights for hotel owners, managers and policy makers regarding the importance of adopting GTL style and investing in EMPs to remain environmentally responsible and ultimately improve FPef levels.
Originality/value
Unlike previous studies that focused on individual-level intermediate variables to explain the indirect relationship between GTL and FPef, this study examined the mediating role of EMPs in the relationship between GTL and FPef at organizational level.

Abstract
Purpose
The study analysed the factors influencing real estate firms' (REFs) decision to adopt virtual reality (VR) technology using the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method. This was done to enhance the practice of real estate agency in Nigeria.
Design/methodology/approach
Data were elicited from eight real estate experts. These experts were heads of the agency department of firms that had been in existence for a minimum of five years in the Lagos property market. The data analysed in this study were collected with the aid of a questionnaire.
Findings
The result revealed that use intention was influenced by performance expectancy, effort expectancy, social influence, facilitating conditions, hedonic motivation, price value and UB. Also, facilitating conditions, habit and use intention did not influence use behaviour. Overall, six constructs, which include price value (Ri − Cj value = 0.1284), use behaviour (Ri − Cj value = 0.0666), social influence (Ri − Cj value = 0.0583), facilitating conditions (Ri − Cj value = 0.0323), performance expectancy (Ri − Cj value = 0.0196) and effort expectancy (Ri − Cj value = 0.0116), were significant predictors of the factors influencing the decision of REFs to adopt VR. Of these constructs, the Ri − Cj values indicated that price value had the highest causative influence.
Practical implications
The result of this study will bring REFs to the consciousness of the factors that could affect their adoption of VR technology. This study will also assist the Nigerian Institution of Estate Surveyors and Valuers in appropriately enlightening REFs on the integration of VR technology into the agency practice especially at this time when all health protocols and guidelines need to be observed to help flatten the curve of the Covid-19 pandemic.
Originality/value
This study is the first to have an insight into the analysis of the factors influencing REFs' decision to adopt VR technology using the DEMATEL method.
