Abstract
The entrepreneurial performance of new ventures operating within the sustainable open innovation paradigm remains underexplored, particularly in terms of how specific sustainability-oriented practices translate into measurable performance outcomes. Prior research has largely examined sustainability, entrepreneurship, and open innovation in isolation, offering limited empirical evidence on their combined effects at the early venture stage. To address this gap, this study analyzes panel data from 407 new ventures incubated in science and technology parks, employing regression-based panel data analysis to examine the relationships between sustainable practices, open innovation engagement, and entrepreneurial performance. The findings suggest that new ventures widely adopt sustainable materials and energy as key strategies, which significantly influence entrepreneurial performance. In contrast, support from local communities does not have a statistically significant impact. Among the sociodemographic factors tested, only the number of years participating in open innovation networks shows a significant effect on entrepreneurial performance. Theoretically, this study advances sustainable open innovation literature by empirically integrating sustainability practices into entrepreneurship performance models. From a managerial perspective, the findings offer actionable insights for entrepreneurs and incubator managers, highlighting which sustainability strategies and network engagements are most likely to yield performance benefits in new ventures.

Abstract
This study aims to explore the integration challenges faced by immigrant entrepreneurs in Portugal. It employed a multiple case study approach, drawing on semi-structured interviews with nine immigrant entrepreneurs from three distinct communities in Portugal. The findings of this study highlight the role of social networks in enabling and shaping the entrepreneurial journeys of immigrants in Portugal. These networks act as a bridge to help immigrants overcome barriers such as unfamiliarity with local markets, restricted access to resources, and cultural differences. In this context, community knowledge and referrals play a particularly significant role. Furthermore, the findings also identify five types of challenges faced by these communities including the financial, regulatory, social, institutional, and psychological dimensions. This study is relevant due to the role of immigrants in fostering economic growth and social cohesion. Understanding and addressing the integration challenges is key to enabling their success, which in turn strengthens local economies and promotes inclusive growth. Additionally, exploring these issues helps policymakers and organizations develop targeted strategies to support immigrant entrepreneurs, ensuring they can fully realize their potential and contribute positively to the host society.

This study investigates how pandemic-induced digitalisation, understood as the transition to remote work combined with the enforced use of digital tools and the reconfiguration of tasks and digital skills at the job level, has affected job security and job quality in Portugal. In 2022, a nationwide survey was administered to employees in companies registered in the country, yielding 2001 valid responses through a stratified random sampling strategy that ensured representation across different firm sizes. Structural equation modelling (PLS-SEM) was used to examine the relationships between digitalisation (independent construct) and perceived job quality and job security (dependent constructs), while controlling for demographic, organisational, and work-regime characteristics. Digitalisation had a significant positive effect on perceived job quality but no systematic effect on perceived job security. The results also revealed more positive perceptions of job security among women, employees in smaller firms, and those working on-site, whereas directors and workers in the Lisbon Metropolitan Area reported greater negative effects. These findings underscore the importance of contextual factors in shaping how workers experience digitalisation and provide evidence to inform public policies aimed at promoting job security and job quality in a post-COVID-19 labour market.
