Abstract

Purpose

Innovation is key. It improves a nations’ standing in international competition and in-creases the productivity of the workforce – a significant aspect in aging societies with a declining entrepreneurial activity. But how can innovation be fostered? This paper argues that entrepreneurial culture is an underestimated solution to this difficult challenge. It therefore differs from common models in which other measures such as financial capital or networks play a predominant role and thus mask the influence of entrepreneurial culture on innovation in entrepreneurial ecosystems.

Design/methodology/approach

Using a qualitative literature analysis, the paper links various interdisciplinary touch points to the entrepreneurial ecosystem – including the individual-focused cognitive aspects of entrepreneurs, the social and spatial communities and the ecosystem as a service model.

Findings

The framework is conceptualized as a multi-layer model, enabling a discussion of policy measures in socioeconomic spaces with a short- and long-term perspective. It dispenses artificial assumptions and considers the complexity of human behavior as a strong and reciprocal driver of entrepreneurial culture.

Practical implications

With this framework, the paper tends to qualify policy makers and researchers in a de-tailed manner, when it comes to the formulation and application of culture-focused innovation policies.

Originality/value

The paper enriches the existing research with a new perspective on the relation between entrepreneurial culture and entrepreneurial ecosystems, which especially emphasizes the entrepreneurs experienced reality and its multi-level embeddedness.

Abstract

Purpose

This study aims to investigate the impact of temperature and fiber volume fraction on the mechanical properties of 3D-printed composites of continuous glass fiber reinforced onyx.

Design/methodology/approach

Continuous glass fiber reinforced onyx (carbon-filled nylon) 3D-Printed composites have been designed and tested at 40°C, 60°C and 80°C for fiber volume fractions ranging from 13%, 20%, 27%, 33% and 40%.

Findings

The results of three-point bending tests have shown that at higher temperatures, i.e. greater than the room temperature the 3D-Printed onyx loses its mechanical properties as obvious for thermoplastic composites. However, the inclusion of high temperature glass fibers has improved the mechanical properties of the onyx polymer and its resistance to deformation at higher temperatures. At all temperatures, the increase in fiber fraction increases the yield strength and decreases the elongation of the composite in the strain region below the yield point. At Vf >0.27 the elongation in samples seems less affected by the fiber content. The comparison of the specimen with different fiber volume fractions (Vf) shows that the elongation of the samples at Vf = 0.4, the samples’ response to the applied load has become independent of the temperature above 40°C.

Originality/value

The experimental and numerically calculated results are well matched, showing the accuracy in the methodology of designing the fiber reinforced onyx composites.

Abstract

Purpose

Crises significantly affect the “people” dimension of the triple bottom line, disrupting careers through economic consequences, reducing organizational trust and altering career choices. Entrepreneurial careers may emerge as an alternative to secure income and career control. Crises can generate career shocks, prompting transitions from traditional employment to entrepreneurship. This study aims to investigate how crises influence career transitions, particularly entrepreneurial intentions, focusing on the effects of layoffs, job insecurity and perceived employability during COVID-19. It explores both direct and indirect impacts of these factors through career shock, contributing to career and entrepreneurship research.

Design/methodology/approach

Cross-sectional data were collected in the United Arab Emirates (UAE) using snowball sampling during the COVID-19 health crisis. The final sample consisted of 211 working individuals. An online questionnaire was distributed to participants. The study hypotheses were tested using Partial Least Squares (PLS) analysis conducted with SmartPLS 3.0.

Findings

The obtained results showed that the layoff of others, job insecurity and low perceived employability are significantly associated with career shock. And that career shock mediates the relationship between these variables and entrepreneurial intention in times of crisis, except for job insecurity.

Practical implications

This research provides insights for employees, managers, organizations and policymakers. It is necessary to carefully address employee expectations and experiences to identify career decisions resulting from career shocks and determine the needed interventions and support.

Originality/value

Very few studies examined the relationship between career shock and entrepreneurial intention. This cannot help human resources management practitioners understand how career shock can trigger the transition from paid employment to an entrepreneurial career. This study broadens the scope of research on human resource management, entrepreneurship and career by examining the direct effects of layoff, job insecurity and perceived employability on career shock as well as on entrepreneurial intention, in addition to their direct effects on the latter through career shock during a crisis.

Abstract

Purpose

With the continued influx of refugees, entrepreneurship is increasingly becoming a viable avenue for refugee socioeconomic integration. The paper examines the effects of mindfulness, refugees’ perceptions of the host community and social capital on refugees’ entrepreneurial abilities, intentions and success.

Design/methodology/approach

The paper uses data from two studies conducted in refugee settlements in Uganda. Study 1 used a sample of 395 refugees, while Study 2 used a sample of 181 refugee entrepreneurs. Serial mediation analyses were conducted for both studies using the PROCESS Macro.

Findings

As hypothesized, mindfulness, perceptions of the host community and social capital were significantly correlated to refugees’ entrepreneurial self-efficacy, alertness and intentions. Mindfulness and perceptions were further correlated with perceived entrepreneurial success. The serial mediation hypothesis of the effects of mindfulness on entrepreneurial self-efficacy, alertness and intentions via refugees’ perception of the host community and social capital was supported. On the other hand, whereas refugees’ perceptions of the host community mediated the effects of mindfulness on entrepreneurial success, social capital did not.

Social implications

The study suggests that socioeconomic integration policies, processes and interventions, especially those promoting refugee entrepreneurship, should pay close attention to the social perceptions between the refugees and the host communities.

Originality/value

The paper provides insights into how mindfulness and perceptions of the host community influence refugees’ social capital and, consequently, their entrepreneurial ability and outcomes. The study suggests that the nature and quality of the social capital of refugees in less developed countries should be given further attention.

Abstract

Purpose

This research explores the drivers that determine the ability of spontaneous volunteer groups (SVGs) to sustain their operations. That sustainability aims to support those affected in the community beyond the response phases of a disaster and into the recovery and mitigation phases to build resilience to the next disaster.

Design/methodology/approach

To investigate the sustainability of spontaneous volunteering that takes place in the aftermath of a disaster, we conducted qualitative interviews in three English locations where groups of spontaneous volunteers emerged following major floods. We analysed our qualitative data using thematic analysis.

Findings

Our findings theorise the drivers of SVG sustainability and present these in four themes: (1) assessment of ongoing needs; (2) organisation of resources to address that need; (3) leadership and followership creating a weight of operational capability and (4) influence of political will. Through exploring these drivers, we uncover key factors to developing a sustainable SVG system including trusted leadership and social capital.

Research limitations/implications

We show how the four drivers interact to support the continuity of SVGs and sustain their operations. This has implications for how leaders of SVGs create a volunteering environment that encourages ongoing involvement and has implications for officials to view SVGs as a support rather than a risk.

Originality/value

The novelty of our paper is in rejecting the argument of the temporal limit of SVGs to the response phase by theorising the drivers that make their operations sustainable for recovery and resilience building to mitigate the next disaster. This includes our examination of the interplay between those drivers.

Abstract

Purpose

Advances in machine learning (ML) have made significant contributions to the development of intelligent and autonomous systems leading to concerns about resilience of such systems against cyberattacks. This paper aims to report findings from a quantitative analysis of literature within ML security to assess current research trends in ML security.

Design/methodology/approach

The study focuses on statistical analysis of literature published between 2000 and 2023, providing quantitative research contributions targeting authors, countries and interdisciplinary studies of organizations. This paper reports existing surveys and a comparison of publications of attacks on ML and its in-demand security. Furthermore, an in-depth study of keywords, citations and collaboration is presented to facilitate deeper analysis of this literature.

Findings

Trends identified between 2021 and 2022 highlight an increase in focus on adversarial ML – 40\% more publications compared to 2020–2022 with more than 90\% publications in journals. This paper has also identified trends with respect to citations, keywords analysis, annual publications, co-author citations and geographical collaboration highlighting China and the USA as the countries with highest publications count and Biggio B. as the researcher with collaborative strength of 143 co-authors which highlight significant pollination of ideas and knowledge. Keyword analysis highlighted deep learning and computer vision as the most common domains for adversarial attacks due to the potential to perturb images whilst being challenging to identify issues in deep learning because of complex architecture.

Originality/value

The study presented in this paper identifies research trends, author contributions and open research challenges that can facilitate further research in this domain.

Purpose

This paper aims to the intricate relationship between digital influencers (DIs) and their followers, aiming to develop a comprehensive framework that explains how influence works in the digital world. It focuses on understanding the cultural aspects that shape these relationships in today’s global and digital marketplace.

Design/methodology/approach

This study employs a holistic methodology, intertwining historical, cultural and theoretical insights to decode the DI phenomenon. Applying a Grounded Theory approach, this paper coded articles into categories, developed abstract concepts and refined them through cycles of literature collection and analysis that allowed identifing gaps in the Influencer Marketing field. This comprehensive review and inductive analysis of globalization, mediated communication and digital interactions aim to unravel the intricacies of digital and virtual influence. This paper’s theoretical development advances propositions that dissect the facets influencing digital adoption, usage, interest and value perception, leading to a detailed model of digital influence grounded in both theory and real-world examples.

Findings

This research uncovers the significant impact DIs have, driven by global connections and the way we communicate in the digital age. Historical context situates DIs within the broader narrative of mediated persuasive communication. A preliminary typology of DIs and influence contexts forms the foundation for further exploration.

Research limitations/implications

This study enhances the discussion around DIs by considering the influence of technology and culture together. It draws from the thoughts of leading thinkers on how technology connects us, providing a strong foundation for future studies.

Practical implications

As digital influence and the surrounding technology continue to change, it’s important to think critically about these trends. This research offers valuable insights for businesses looking to navigate the digital landscape effectively, helping them make better strategic decisions about their online presence.

Originality/value

This study breaks new ground by offering a detailed categorization of DIs and proposing a fresh way to understand their role. It links important ideas from the past about persuasion through media to the current state of digital influence, offering insights into how digital trends might affect communication strategies.
