Abstract
The purpose of this paper is to grasp the connection between entrepreneurial ecosystems and sustainable entrepreneurship and its relevance for tackling societal challenges. In particular, the work investigates if entrepreneurial ecosystems, through the lens of education and social context, simulate social entrepreneurial orientation. To accomplish the research goals, an empirical study is conducted relying on Global Entrepreneurship Monitor from 2015, where 58 countries are analyzed based on the Entrepreneurial Ecosystem Taxonomy. The results point that education and social context are supporters of social entrepreneurship, emphasizing on both institutional and social networks role. However, the findings reveal that social context tends to instigate more regular entrepreneurship when compared to social entrepreneurship, although being a driver in both cases. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Abstract
This paper aims to identify and analyze project management maturity models in order to identify those best suited to be adopted in construction firms. To do so, models from papers available in academic repositories were analyzed. To be successful, the construction business deeply depends on projects outcomes; thus, the implementation of project management maturity models is important for this sector. A maturity model is a valuable technique to assess project management capabilities within a single part of an organization or to assess an organization as a whole. Its main purpose is to provide a means to create a more organized and predictable way for organizations to achieve their goals, increasing their chances of success regarding the outputs, outcomes, and benefits. In this paper, documentary research was performed to identify available project management maturity models and togather information about their performance. The information gathered was used to find elements to be compared with the identified models. Reviewing the literature, 39 project management maturity models were identified. The authors selected two PMMMs that were well fitted to assess the project management capabilities in construction firms: OPM3 and MMGP Prado.

Abstract
Cities are becoming increasingly complex to manage, as they increase in size and must provide higher living standards for their populations. New technology-based solutions must be developed towards attending this growth and ensuring that it is socially sustainable. This paper puts forward the notion that these solutions must share some properties: they should be anthropocentric, holistic, horizontal, multi-dimensional, multi-modal, and predictive. We propose an architecture in which streaming data sources that characterize the city context are used to feed a real-time graph of the city's assets and states, as well as to train predictive models that hint into near future states of the city. This allows human decision-makers and automated services to take decisions, both for the present and for the future. To achieve this, multiple data sources about a city were gradually connected to a message broker, that enables increasingly rich decision-support. Results show that it is possible to predict future states of a city, in aspects such as traffic, air pollution, and other ambient variables. The key innovative aspect of this work is that, as opposed to the majority of existing approaches which focus on a real-time view of the city, we also provide insights into the near-future state of the city, thus allowing city services to plan ahead and adapt accordingly. The main goal is to optimize decision-making by anticipating future states of the city and make decisions accordingly.

Abstract
Nowadays we are facing the emergence of new challenges, especially focused on environmental behavior and climate change and also the effects and impacts of COVID-19 world pandemic - which can restrain the attainment of the desired sustainability. It is, then, mandatory to reply to all of these challenges through the design of specific paths to attain sustainable development in a collective approach, with the involvement and the commitment of the community and performed in an integrated way. Thus, it is proposed a trans-disciplinary research method based on the European Union title recognition - European Green Capital (EGC) -, directly related to the Circular Economy (CE), together with a Data Envelopment Analysis (DEA). This paper highlights sustainable measures and proposes common managerial strategies and policies, that can support the cities/regions' sustainable practices embedding as well as ensure its overall monitoring to measure if the actions implemented through time are adequate and efficient towards attaining CE and sustainable development. Those are based on the analysis of the best practices of the EGC, which can impact on CE, and using DEA. This approach can follow the city/region evolution and be adapted to the EGC evaluation parameters in order to understand the main characteristics that can contribute to improve governance approaches and help to foster CE into all the cities/regions' ecosystem. © 2021 IEEE.

Abstract
Abstract The increased adoption of IoT and analytical devices, telecommunication systems, smart sensors, and diverse information systems have brought significant impacts to Industry 4.0. To respond to this rapid technological evolvement is essential to ensure a proper articulation of HEI (Higher Education Institutions) with industry, to better prepare graduates with the appropriate competencies and technological capabilities within the digital transition of the industry. This paper aims to present a research project developed in digital transformation amongst HEI students, in the Alto-Minho region disclosing the trigger points to increase the digital adoption and embedding of Industry 4.0 paradigm. The obtained results enabled to conclude an apparent low level of digital literacy, a lack of vision and awareness about the technology potentialities throughout industry activities, besides its use almost restricted to leisure and as study support, as well as lack on cybersecurity domain-specific competencies.

Abstract
Nowadays, Project Management is facing a more complex and dynamic environment, mostly because of the recent fourth industrial revolution, called Industry 4.0. The digitisation and the characterisation of all of the assumptions, methodologies, and processes of the Industry 4.0 can cause disruptive effects for the traditional project management and the role of the project manager. This new paradigm requires a more active role from the project manager, accompanied by new technical, contextual and behavioural competencies. In line with this, this work aims to identify the skills or competencies that the project manager must present to follow the fourth technological revolution. To accomplish this task, the most relevant concepts that are associated with industry 4.0 and with the project manager competencies are presented. From the literature review, it is possible to conclude the existence of more behavioural or soft skills associated with the 4.0 project manager profile, compared to the traditional project manager profile.
