The paper uses a relational view of strategy framework to measure and assess the sustainable success of base of the pyramid (BoP) projects. The authors posit that the relational view is a powerful way to determine if a firm's project might lead to sustainable competitive advantage, because if partner resources combine to create relation‐specific capabilities and competences, they may provide sustainable value, and the paper applies this method of strategic analysis to selected BoP projects.

The paper separates the secondary data analysis from the primary data analysis and offers four propositions, based on the combined relational view and BoP criteria. The authors apply the relational view framework to two BoP projects from Michigan‐based organizations. Each case is analysed using the framework, and the authors discuss how the resources of each of the BoP project partners create value, how tailored and scalable the projects are, how BoP end user needs are addressed, what resources partners contribute, and if the relation‐specific combination of resources create project level capabilities that are sustainable.

The sustainable success of BoP projects may be best achieved when the BoP project partners contribute valuable resources and when those resources combine to create relation‐specific capabilities that create sustainable success. It reinforces the importance of scale, BoP user needs, and engaging BoP customers as partners.

This paper tries to help explain why some BoP projects successfully create a sustainable competitive advantage, by building on strategic themes and using a variation of the relational view framework to examine resources and capabilities of the organizations that partner to serve people at the BoP.

This study aims to explore the strategic integration of Sharia-compliant and environmental, social and governance (ESG)-focused investments within global equity portfolio optimization frameworks, with a particular emphasis on variance minimization and dynamic rebalancing techniques.

The research uses historical data from Sharia-compliant, ESG-focused and conventional equity exchange-traded funds (ETFs). Advanced mean-variance optimization methodologies via quadratic programming are employed, encompassing static optimization with and without a 50% cap on individual asset weights, dynamic optimization with monthly rebalancing and rolling window optimization.

Portfolios integrating Sharia-compliant investments frequently outperform those composed solely of conventional equity ETFs. Dynamic optimization with monthly rebalancing achieved the highest Sharpe ratio (1.3708) and demonstrated enhanced portfolio resilience during market turbulence, such as the COVID-19 pandemic. Sharia-compliant investments showed substantial allocations during key periods, with weights reaching up to 100% in the first half of 2020. In contrast, ESG-focused investments exhibited more limited and sporadic allocations, reflecting a more opportunistic role in the portfolio.

The findings reaffirm the critical role of Sharia-compliant investments in well-diversified, risk-conscious portfolios while also providing nuanced insights into the more selective integration of ESG-focused assets. The results offer practical guidance for portfolio managers seeking to integrate ethical and sustainable investment principles within advanced portfolio optimization frameworks, particularly when focusing on minimizing variance and dynamically responding to evolving market conditions.

The study contributes to the growing body of literature on ethical and sustainable investments, demonstrating that it is possible to balance ethical considerations with robust financial performance. The research underscores the potential for Sharia-compliant investments to play a significant role in global portfolios, potentially fostering greater financial inclusion and cross-cultural understanding in the investment community.

This research provides novel insights by focusing on Sharia-compliant investments within non-Muslim countries, an area that has been relatively underexplored. It also compares the outcomes of static, dynamic and rolling optimizations, highlighting the dynamic interplay between ethical investment principles and financial performance.

Family businesses (FBs) are considered an essential type of entrepreneurship that impacts economic growth. However, statistics show that after a period of performance they ultimately fail, and comparatively little is known about the reasons for their failing when compared to the amount of research focusing on keys to success.

Through the implementation of an case study technique, which is widely used in research to address the complex phenomenon of failure, this paper aims to analyse the antecedents of failure in the case of four Catalan FBs. In doing so, this article develops propositions based on Institutional Economics Theory and Dynamic Capability Theory, with a focus on innovation and product diversification in family firms.

Using interviews as a means of obtaining a large amount of information, it is observed that problems related to governmental regulations and constantly changing social behaviour can lead to failure for FBs. Additionally, a link between R&D activities and new product development and FB failure is observed. More specifically, this research highlights that a lack of product diversification and innovation can become a hindrance for FB performance when the institutional environment is unstable. It reveals the importance of developing dynamic capabilities that can meet the demands of fast-changing consumer behaviour. From a practical perspective, these findings can be used by governments in developing regulations focused on the dynamic capabilities of FBs, and by managers in order to learn from these experiences and implement appropriate strategies for long-term development and crisis management.

This paper theoretically contributes to both the FB literature, as well as to institutional economics and dynamic capability theories by offering a combined perspective on how FB's dynamic capabilities change based on environmental factors and impact FB failure.

Being literate can change the lives of Australian students. Therefore, graduating effective teachers of literacy is an imperative for Australian schools. Professional experience provides an opportunity for preservice teachers to refine their skills for teaching literacy under the guidance of a mentor teacher. This study investigates from the perspective of preservice teachers, the attributes and practices primary mentor teachers demonstrate when mentoring literacy teaching during professional experience.

This investigation utilised survey design to gather data from primary preservice teachers (n = 402) from seven Australian universities. The 34 survey items were underpinned by the Five Factor Model of Mentoring and literacy practices prescribed by the Australian curriculum. Preservice teachers self-reported their responses about their literacy mentoring experiences on a five-point Likert scale. The Five Factor Model of Mentoring provided a framework to analyse and present the data using descriptive statistics.

Findings revealed 70% or more of preservice teachers agreed or strongly agreed mentor teachers had the personal attributes, shared the pedagogical knowledge, modelled best practice and provided feedback for effective literacy teaching. Conversely, only 58.7% of the participants reported their mentor teachers shared the system requirements for effective literacy teaching.

The preservice teachers self-reported their experiences, and although this may be their experience, it does not necessarily mean the mentor teachers did not demonstrate the attributes and practices reported, it may mean they were not identified by the preservice teachers. While there were 402 participants in this study, the viewpoints of these preservice teachers' may or may not be indicative of the entire population of preservice teachers across Australia. This study included primary preservice teachers, so the experiences of secondary and early childhood teachers have not been reported. An extended study would include secondary and early childhood contexts.

This research highlighted that not all mentor teachers shared the system requirements for literacy teaching with their mentee. This finding prompts a need to undertake further research to investigate the confidence of mentor teachers in their own ability to teach literacy in the primary school. Teaching literacy is complex, and the curriculum is continually evolving. Providing professional learning in teaching literacy will position mentor teachers to better support preservice teachers during professional experience. Ultimately, the goal is to sustain high quality literacy teaching in schools to promote positive outcomes for all Australian school students.

While the role of mentor teacher is well recognised, there is a dearth of research that explores the mentoring of literacy during professional experience. The preservice teachers in this study self-reported inconsistencies in mentor teachers' attributes and practices for mentoring literacy prompting a need for further professional learning in this vital learning area.

The purpose of this paper is to provide an overview of family entrepreneurship and internationalization strategies by discussing the papers in this special journal issue.

The main research areas related to family business are discussed in terms of socioemotional wealth and societal trends. A review of the literature is conducted to highlight the emerging themes affecting the decision of family businesses to internationalize.

The paper stresses how it is important to have an entrepreneurial approach to internationalization of family businesses.

As more family businesses are born globals, it is important to focus on the positive aspects of internationalization, including emerging markets and gaining important entrepreneurial knowledge.

Family businesses need to be more innovative and risk-taking in their approach to internationalization as it helps them build their reputation and increase performance.

As there are limited studies about family entrepreneurship and internationalization in terms of a broad view of family, this paper takes an inclusive approach to the changing nature of how a family is defined in today’s global society.

The levels of work-related stress and the incidence rates of subsequent related illnesses are increasing in our society, leading to high individual and socioeconomic burdens. Mindfulness training has been shown to be an effective method of improving stress resilience. This paper aims to investigate the efficacy of nature-based mindfulness training in professionals with high levels of work-related stress.

In this controlled pilot study, a total of 56 volunteers completed a nature-based mindfulness training progam and were compared to 8 participants (waitlist controls). Psychometric assessments were performed at baseline and after two and four months of training.

After two months of training, the scores for self-efficacy, sense of coherence, level of mindfulness and overall psychiatric symptom load had significantly improved in the intervention group, while the control group did not show any significant improvements. A comparison between the intervention and control groups showed a significant difference regarding the sense of coherence only.

Since this was an exploratory study with a small control group, further studies are needed to verify our findings.

In conclusion, nature-based mindfulness training seems to be a promising tool for the improvement of resilience and overall psychological health in professionals.

This was the first study to systematically investigate effects of nature-based mindfulness training in people with high work-related stress.

The 3,4-methylenedioxymetamphetamine (MDMA) content in ecstasy tablets has increased enormously throughout Europe across the past decade. This study aims to determine whether this is caused by the production of “stronger” tablets (more mg MDMA per mg of tablet), or if tablets have simply been getting larger and heavier (more mg of tablet in total).

A data set of 31,716 ecstasy tablets obtained in 2012–2021 by 10 members of the Trans European Drug Information (TEDI) network was analysed.

The MDMA mass fraction in ecstasy tablets has remained virtually unchanged over the past 10 years, with increased MDMA contents being attributed almost exclusively to increased tablet weight. These trends seem to be uniform across Europe, despite varying sampling and analytical techniques being used by the TEDI participants. The study also shows that while tablet weight correlates perfectly with MDMA content on a yearly basis, wide variations in the MDMA mass fraction make such relations irrelevant for determining the MDMA content of individual tablets.

These results provide new opportunities for harm reduction, given that size is a tangible and apparently accurate characteristic to emphasise that one tablet does not simply equate to one dose. This is particularly useful for harm reduction services without the resources for in-house quantification of large numbers of ecstasy tablets, although the results of this study also show that chemical analysis remains crucial for accurate personalised harm reduction.

The findings are both new and pertinent, providing a novel insight into the market dynamics of ecstasy tablet production at a transnational level.

This article seeks to address aviation as an emerging biofuel consumer and to discuss sustainability issues and consequences for feedstock production concepts. Biojet fuels have been identified as a promising, readily deployable alternative to fossil‐based aviation fuels. At the same time they are highly criticised as their production may have negative social and environmental impacts. Therefore, the paper aims to identify major sustainability issues and assessment challenges and relate these to the production of biojet fuel feedstock.

Two plant oil production concepts are presented that address the sustainability issues discussed. Both concepts are being investigated within the research project “Platform for Sustainable Aviation Fuels”. A literature‐based overview of sustainability issues and assessment challenges is provided. Additionally, conceptual insights into new plant oil production concepts are presented.

The use of biojet fuels is often hailed as a strategy for the aviation industry to become more sustainable. However, biofuels are not necessarily sustainable and their potential to reduce GHG emissions is highly debated. Several unresolved sustainability issues are identified highlighting the need for improved assessment methods. Moreover, the two concepts presented have the potential to provide sustainably grown feedstock, but further empirical research is needed.

This article addresses researchers and practitioners by providing an overview of sustainability issues and assessment challenges related to biojet fuels. Consequences are identified for two plant oil feedstock concepts: catch cropping in temperate regions and silvopastoral systems in tropical and subtropical regions.
