Abstract
This study adopts an integrative review approach to explore the differences and similarities between smart cities and sustainable cities. The research starts by performing two systematic literature reviews about both paradigms and, after that, employs a thematic analysis to identify key themes, definitions, and characteristics that differentiate and connect these two urban development concepts. The findings reveal more similarities than differences between the two paradigms. Despite this, some key differences are identified. Smart cities are characterized by their use of advanced information and communication technologies to enhance urban infrastructure, improve public services, and optimize resource management. In contrast, sustainable cities focus on environmental conservation, social equity, and economic viability to ensure long-term urban resilience and quality of life. This study is important because it clarifies both concepts and highlights the potential for integrating smart and sustainable city strategies to address contemporary urban challenges more holistically. The findings also suggest a convergence towards the concept of 'smart sustainable cities', which leverage technology to achieve sustainability goals. Finally, this study concludes by identifying research gaps and proposing a future research agenda to further understand and optimize the synergy between smart and sustainable urban development paradigms.

Abstract
Purpose: Responsible innovation assessment tools (RIATs) are key instruments that can help organizations, associations and individuals measure responsible innovation. Accordingly, this study aims to review the current status of research on responsible innovation and, in particular, of studies that either present the relevance of RIATs or provide empirical evidence of their adoption. Design/methodology/approach: A systematic literature review is conducted to identify and review how RIATs are being addressed in academic research and the applications that are proposed. A systematic process is implemented using the Web of Science and Scopus bibliographic databases, aiming not only to summarize existing studies, but also to include a perspective on gaps and future research. Findings: A total of 119 publications were identified and included in the review process. The study identifies that RIATs have attracted growing interest from the scientific community, with a greater predominance of studies involving qualitative and mixed methods. A well-balanced mix of conceptual and exploratory studies is also registered, with a greater predominance of analysis of RIATs application domains in the past years, with greater incidence in the finance, water, energy, construction, manufacturing and health sectors. Originality/value: This study is pioneering in identifying 16 dimensions and 60 sub-dimensions for measuring responsible innovation. It also suggests the need to include multidimensional perspectives and individuals with interdisciplinary competencies in this process.

Abstract
Senior entrepreneurship is getting increasing prominence in research, academia, and business. Given the demographic shifts occurring in Western Europe, it is also becoming a nuclear topic of interest for policymakers. Still, existing literature overlooked the emergent trend encompassing older individuals which, with different leitmotifs, starting-up new enterprises after decades as employees. In doing so, they convey formal and informal knowledge, networks, experience, savoir faire, and financial endowments, nurtured along the years, which is an evident advantage compared to the younger counterparts. Due to the raising number of negative experiences in the job market, either in getting or maintaining a position, senior workers look up for alternatives. Sometimes being pushed by necessity, other times pulled by opportunity identification and independence, seniors are increasingly making their best to overcome unsatisfying or insufficient conditions as employees. Enhancing entrepreneurial initiative across older individuals is urgent for policy makers due to the need to find occupation for an aging population and their contribution to income generation, at the same time, social and human capital will be leveraged, multiplying the effects of other policy actions such as education. Using the GEM database, this article aims to offer an overview on the role of age in entrepreneurial intention and its nature, addressing the nonlinearities of the effect. This new methodological framework can be used as a basis for future empirical research on the topic of senior entrepreneurship; additionally, it aims contributing to a better understanding of the role of age in shifting the individual reasons for starting a business, controlling for other individual characteristics. The identification of the particular features of the different age cohorts along with gender, education, social context or macro-economic contexts will shed some light on the specific policy packages needed to reinforce the entrepreneurial initiative as a vehicle to promote sustainable and inclusive growth along the European Countries.
