Hydrogen fuel cells could play an important role in meeting the challenges of the Two Degrees Scenario. The purpose of this paper is to review the development of this technology in South Africa with the aim of understanding how the country can transform its existing socio-technical systems and act to support a hydrogen-based technological innovation system (TIS).

A mixed methods approach has been followed in this study. Secondary data analysis was used initially to build a profile of South Africa’s present energy system, followed by a stakeholder survey of the emerging hydrogen economy. Respondents were selected based on a convenience/snowball sampling approach and were interviewed using a semi-structured questionnaire, covering opportunities for South Africa in the global hydrogen economy; sources of competitive advantage; the present phase of development; the maturity of each function and the main weaknesses within the TIS; and finally the appropriate policy instrument to remedy the weakness and/or maximise opportunities for local companies.

The research has shown that the hydrogen economy is still at a pre-competitive level and requires ongoing government support to ensure an energy transition is realised. In particular, it is important that niche experimentation, a proven strategy in respect of successful sustainability transitions, is further pursued. Importantly, the net cost of hydrogen-based transportation, which is still several times larger than the cost of transport based on the internal combustion engine (ICE), must be reduced, especially in the key applications of public transport and underground vehicles. Furthermore, the development of digital technologies to manage supply fluctuations in energy grids must be accelerated.

The South Africa economy will be severely affected by the replacement of the ICEs with battery electric vehicles due to the country’s reliance on ICEs for platinum demand. Fuel cells represent a new market for platinum but the hydrogen TIS is still at a vulnerable point in its development; without policy support, it will not contribute to a successful socio-technical transformation, nor provide an alternative outlet for platinum.

Food waste is increasingly becoming a major issue for retail companies. However, there is still limited knowledge of how new forms of collaborative consumption (CC) may impact firms' behavior. This paper identifies and examines how the enablers of food waste and firms' tendency to cooperate with their customers may affect the adoption of measures oriented to diminish waste reduction, as well as the use of mobile technologies.

A empirical study has been conducted on a sample of international firms operating in the food sector as retailers (i.e. restaurants, bar and catering services) or in similar activities (i.e. hotels and accommodations). The authors tested an empirical model aimed at revealing the possible mediating role of customer cooperation in affecting the impact of food waste enablers on (1) waste recovery measures and (2) the adoption of mobile technologies for food recovery.

The results of this study showed how customer cooperation mediates the impact of food waste enablers on the intention to use mobile applications for food recovery but not on the adoption of food recovery measures that, instead, mainly depends on waste causes internal to the firm.

This is one of the first studies that tries to identify and evaluate the impact of the different enablers of food waste on firms' pro-environmental behaviors. Interestingly, the authors show how customer cooperation is a decisive factor to promote new forms of CC in the food industry. Importantly, customer cooperation acts as a bridge between the drivers of food waste and a firm's intention to adopt measures against it. By actively involving customers, firms can gain insights, develop effective strategies and foster a culture of waste reduction that benefits both the business and the environment.

This study aims to understand the house owners' energy concerns. An exploratory inductive research design has been chosen to explore the perceptions of households towards the modernization of energy use in residential buildings. Face-to-face interviews with experts and households were conducted in Baden-Württemberg, Germany to collect the data. This study found that most of the house owners do not know about the benefits of increasing the energy performance in residential buildings and which energy efficiency potentials they can acquire. Additionally, house owners’ superficial knowledge creates fears and doubts concerning the modernization of energy use in residential buildings. Moreover, this study found that the local public administration, such as the municipalities, has a good reputation among households. Hence, public marketing activities should be run locally. It is suggested that the public administration should not conduct any public marketing activities without the support, for example, of the mayor. Further, it is necessary to supply the house owners with clear and understandable information on the topic and to demonstrate the functionality of the technologies to increase energy efficiency in residential buildings. Moreover, interpersonal communication such as a hotline and personal advisory service concerning energy-efficient refurbishment of residential buildings can be very beneficial to support the households. Local public administration should aim to introduce public marketing activities to enhance the modernization of energy use in residential buildings.

The “chiralisation” of Euclidean polygonal tessellations is a novel, recent method which has been used to design new auxetic metamaterials with complex topologies and improved geometric versatility over traditional chiral honeycombs. This paper aims to design and manufacture chiral honeycombs representative of four distinct classes of 2D Euclidean tessellations with hexagonal rotational symmetry using fused-deposition additive manufacturing and experimentally analysed the mechanical properties and failure modes of these metamaterials.

Finite Element simulations were also used to study the high-strain compressive performance of these systems under both periodic boundary conditions and realistic, finite conditions. Experimental uniaxial compressive loading tests were applied to additively manufactured prototypes and digital image correlation was used to measure the Poisson’s ratio and analyse the deformation behaviour of these systems.

The results obtained demonstrate that these systems have the ability to exhibit a wide range of Poisson’s ratios (positive, quasi-zero and negative values) and stiffnesses as well as unusual failure modes characterised by a sequential layer-by-layer collapse of specific, non-adjacent ligaments. These findings provide useful insights on the mechanical properties and deformation behaviours of this new class of metamaterials and indicate that these chiral honeycombs could potentially possess anomalous characteristics which are not commonly found in traditional chiral metamaterials based on regular monohedral tilings.

To the best of the authors’ knowledge, the authors have analysed for the first time the high strain behaviour and failure modes of chiral metamaterials based on Euclidean multi-polygonal tessellations.

The purpose of this paper is to analyze farmer behavior, considering their attitude toward food waste with particular focus on their involvement in the last phase of the process, the retail phase. It assesses the different approaches applied to food waste management and its future.

A sample of 35 farmers in the Porta Palazzo market, the biggest food market in the Turin Area (north-west Italy), was identified and a survey was carried out to determine the behavior and perception of farmers regarding food waste and the management of unsold food.

Results show that there is a high level of interest on the ethical and charitable aspects of food waste and unsold food. However, awareness and knowledge of the initiatives organized by institutions are not sufficient.

If policy makers and institutions have an understanding of farmer behavior, they can implement ad hoc initiatives to reduce food waste and build on the work already done by farmers. Additionally, farmers can help customers to better understand the products.

This study analyzes the perception of the food waste phenomenon for one type of traditional operator in the food supply chain, the farmer. The originality of the paper lies in the fact that it has not only considered the perception of food waste but also the management of unsold food in a market area.

The purpose of this paper is to contribute to the entrepreneurship theory in family firms as it focuses on the relevance of an ambidextrous entrepreneurial strategy (Helfat and Peteraf, 2009), thanks to an effective combination between exploitation and exploration activities. The study refers to the food sector, characterized by established food traditions and changing consumption patterns.

After reviewing the topics, the authors referred to Goel and Jones (2016) for its representativeness for the research. The authors conducted an explanatory case study in which the authors identified the framework’s three sub-systems impacting the above family business systems. The case study is relevant because Eataly, a family-owned and -managed firm, is gaining recognition while applying a strong entrepreneurial strategy and it is unique in the world for the strength of its commercial strategy and dimensions.

Entrepreneurship strategies can be explained by combined organizational antecedent conditions, represented by three sub-systems: family, business and ownership. The sub-systems’ features and their interrelations play a relevant role in influencing entrepreneurial exploration and exploitation processes.

The study contributes to the actual entrepreneurship theory in family firms because it indicates the relevance of an ambidextrous entrepreneurial strategy, thanks to a combination of exploitation and exploration activities. In addition, it analyses the so-called antecedent conditions in organizations to achieve this favorable combination. Limitations involve the case study method and interview technique, both of which could be expanded.

Several practical implications follow for different stakeholder categories (food sector companies, investors and private/public entities) concerning the management of antecedent conditions, the consequences of entrepreneurial investment policy, and tourism and territorial development.

This research is novel because it combines an ambidextrous entrepreneurship approach (Goel and Jones, 2016) with the family firm’s sub-systems (Tagiuri and Davis, 1982), observing how these sub-systems are relevant to defining and managing effective entrepreneurship strategy in a family food firm. The value added is particularly relevant in the food sector, which is characterized by low research and development. In addition, it requires innovative approaches to stimulate customers’ perception of market demand, to satisfy their needs and to sustain family firms in a highly competitive environment.

The data economy, emerging from the current hyper-technological landscape, is a global digital ecosystem where data is gathered, organized and exchanged to create economic value. This paper aims to shed light on the interplay of the different topics involved in the data economy, as found in the literature. The study research provides a comprehensive understanding of the opportunities, challenges and implications of the data economy for businesses, governments, individuals and society at large, while investigating its impact on business value creation, knowledge and digital business transformation.

The authors conducted a literature review that generated a conceptual map of the data economy by analyzing a corpus of research papers through a combination of machine learning algorithms, text mining techniques and a qualitative research approach.

The study findings revealed eight topics that collectively represent the essential features of data economy in the current literature, namely (1) Data Security, (2) Technology Enablers, (3) Business Implications, (4) Social Implications, (5) Political Framework, (6) Legal Enablers, (7) Privacy Concerns and (8) Data Marketplace. The study resulting model may help researchers and practitioners to develop the concept of data economy in a structured way and provide a subset of specific areas that require further research exploration.

Practically, this paper offers managers and marketers valuable insights to comprehend how to manage the opportunities deriving from a constantly changing competitive arena whose value is today also generated by the data economy.

Socially, the authors also reveal insights explaining how the data economy features may be exploited to build a better society.

This is the first paper exploring the data economy opportunity for business value creation from a critical perspective.

This study aims to take a holistic perspective to investigate how open innovation supports sustainability and the contribution to the Unite Nations (UN) Sustainable Development Goals (SDGs).

The study is based on an in-depth single case study of Andriani SpA, a leading Italian company in the food industry. The case is built by triangulating data from direct observations, documentary analysis and semi-structured interviews.

The findings show an organization that has developed its competitive advantage by adopting open innovation to embed sustainability in its strategy and business model. The case study complements the understanding of how open innovation can effectively drive strategic renewal and innovation activities to address sustainability objectives in the food industry.

This study contributes to theoretical development by offering new and insightful explanations of firms' strategic behaviour and coevolution toward sustainability via open innovation. It provides practitioners, policymakers, researchers and students with reflections and inspiration about how open innovation may be deployed to support a holistic strategic renewal aimed at sustainability objectives, such as the SDGs, in the food industry.

The purpose of this research is to explore the relationships between entrepreneurial engagement and their impact on happiness and well-being. By exploring deeper into these relationships, this study seeks to move beyond traditional perspectives on entrepreneurship and uncover new insights.

Primary data collection through an online questionnaire across diverse social media platforms investigates the relationships among entrepreneurial engagement, well-being and happiness. It also examines the moderation effects of work–life balance and financial stability on these relationships.

This study reveals a positive association between entrepreneurship, well-being and happiness. Financial stability positively correlates with entrepreneurship, whereas work–life balance moderates the relationship between entrepreneurial engagement, well-being and happiness.

The cross-sectional design limits causal inference, and the reliance on self-reported data may introduce biases. Future longitudinal research could offer a more comprehensive understanding of these processes over time.

This study provides new insights into the impact of entrepreneurship on well-being and happiness, offering practical recommendations for the business community. It highlights the importance of work–life balance and financial stability in entrepreneurial success.

The research underscores the societal impact of supporting entrepreneurship, suggesting that policymakers and community leaders can use these findings to create supportive environments that enhance well-being and happiness through entrepreneurial engagement.

To the best of the authors’ knowledge, this study includes the first research that has analysed the impact of entrepreneurship on well-being and happiness in the Republic of Kosovo.
