Abstract
STEM areas (Science, Technology, Engineering and Math) are continuously growing but the number of technical workers do not accompany that growth. As the 21st century brings new challenges, students should be prepared for an increasingly complex life and work environments that will privilege proficiency in Learning and Innovation Skills that include Creativity and Innovation, Critical Thinking and Problem Solving, Communication and Collaboration. Also, the need to continuously explore new pedagogical practices in teaching and learning creates an opportunity to build new contents by balancing a stable and tested curriculum with new tools that stimulate creativity, allowing students to better understand the world they live in. This article describes the development of an educational robotics kit, aimed at children and teens from 8 to 18 years old, meant to work as an interdisciplinary teaching tool that can be applied directly in a curriculum.

Abstract
Current research on imbalanced data recognises that class imbalance is aggravated by other data intrinsic characteristics, among which class overlap stands out as one of the most harmful. The combination of these two problems creates a new and difficult scenario for classification tasks and has been discussed in several research works over the past two decades. In this paper, we argue that despite some insightful information can be derived from related research, the joint-effect of class overlap and imbalance is still not fully understood, and advocate for the need to move towards a unified view of the class overlap problem in imbalanced domains. To that end, we start by performing a thorough analysis of existing literature on the joint-effect of class imbalance and overlap, elaborating on important details left undiscussed on the original papers, namely the impact of data domains with different characteristics and the behaviour of classifiers with distinct learning biases. This leads to the hypothesis that class overlap comprises multiple representations, which are important to accurately measure and analyse in order to provide a full characterisation of the problem. Accordingly, we devise two novel taxonomies, one for class overlap measures and the other for class overlap-based approaches, both resonating with the distinct representations of class overlap identified. This paper therefore presents a global and unique view on the joint-effect of class imbalance and overlap, from precursor work to recent developments in the field. It meticulously discusses some concepts taken as implicit in previous research, explores new perspectives in light of the limitations found, and presents new ideas that will hopefully inspire researchers to move towards a unified view on the problem and the development of suitable strategies for imbalanced and overlapped domains.

Abstract
Digital transformation is a challenge that many SMEs find difficult to embrace. This difficulty is not due to a lack of will or resources but to the lack of the right strategies for the specific type of organization. It is a common and accepted opinion that many of the digital transformation projects fail or do not achieve the proposed objectives because of the chosen strategy. Digital transformation cannot be seen as a mere evolution of technologies but as a need to shape the entire business of the organization. The increase in e-commerce has forced SMEs to embark on this disruptive process based on globalization and digital business. In this work, we seek to understand which kind of strategy an SME in the retail industry should follow for a correct transformation of its business model. In this work, is proposed a conceptual model for the digital transformation of retail SMEs and explained how to create a prototype script to support the choice of the best digital strategy for retail SMEs. To prove the validity of the prototype, it has been applied in a practical case of a business process in a retail SME. © 2022 Elsevier B.V.. All rights reserved.

Abstract
Purpose This study aims to present a practical approach to recognizing leadership styles by adopting a serious game in the context of an entrepreneurship course in higher education. Design/methodology/approach The action-research methodology is adopted to explore how the various leadership styles are perceived and assimilated by students. Furthermore, students are organized into eight groups to explore this phenomenon through a thematic analysis. Findings The findings reveal that transformational and transactional leadership can coexist and be applied in organizational management. The results also indicate that students with relevant professional experience have a greater ability to identify the benefits and challenges associated with each leadership style as they recognize these styles throughout their professional careers. Originality/value This paper mainly offers practical implications by presenting an alternative and complementary approach to exploring leadership styles. Through this approach, students can recognize the various leadership styles in the game personas and realize their impact on the dynamics of an organization.

Abstract
Innovation is one of the key aspects that drive economic growth and social welfare, one of the ways that it occurs is through technology transfer. However, using a patent to innovate through technology transfer is a complex process, full of uncertainties, and there is not a well-defined process available that enables entrepreneurs to develop business models based on patents. Therefore, this study aims to develop a methodology to support entrepreneurs in the development of businesses from patents available in technology transfer programs. The P2B methodology was developed within two research steps. Firstly, based on a structured literature review and on the case study analysis of the European Space Agency Business Incubation Center (ESA BIC), an initial conceptualization of the methodology was developed. Secondly, data was collected throughout thirteen semi-structured interviews with experts in technology transfer and management, innovation, and business model development to create the final proposed P2B methodology. The P2B methodology addresses the inherent challenges of the innovative business development process, specific to the technology transfer context, by providing a set of twenty-three activities, supported by sixteen tools, divided into four major phases: technology analysis, value analysis, business model, and business plan.
