Multinational Enterprises (MNEs) periodically decide on both which products to launch (or phase out) and in which global regions, thereby conducting an integrated products-countries consideration in diversification strategies. Over time, these diversification decisions can have a cumulative impact on the structure. Diversification literature has pr...

This study proposes a multilevel conceptual framework for a deeper understanding of the relationship between employee well-being and innovativeness. We overview 49 years of well-being research [1972-2021] and 54 years of research on innovativeness [1967-2021] to uncover 24 dominant themes in well-being and ten primary topics in innovativeness resea...

Technology and innovation management is vital emerging research fields. Technological Forecasting and Social Change (TFSC) has worked as a major forum in this field and is currently regarded as the leading journal. However, an increasing number of publications hamper a comprehensive understanding of the field and journal. In this study, we conducte...

This paper studies the difference between startup investments by private equity funds (buyout funds; PE) and venture capital funds (VC). PEs, which have traditionally invested in mature companies, have been increasingly investing in later-stage startups in recent years. Based on Crunchbase’s data on EU startup investments from 2011 to the first hal...

Solutions that engage the public are needed to tackle air pollution. Technological approaches are insufficient to bring urban air quality to recommended target levels, and miss out on opportunities to promote health more holistically through behavioural solutions, such as active travel. Behaviour change is not straightforward, however, and is more...

This article surveys topic distributions of the academic literature that employs the terms bibliometrics, scientometrics, and informetrics. This exploration allows informing on the adoption of those terms and publication patterns of the authors acknowledging their work to be part of bibliometric research. We retrieved 20,268 articles related to bib...

The present article explores 98 years of creativity research [1922–2020] covering more than 38,000 academic articles on the topic. By applying computational methods rooted in network analysis and text mining, we uncover a history of creativity research spread through 12 major topics of inquiry, including, among others, the psychology of creativity,...

Interdisciplinary research (IDR) has become an important component in the conduction of leading-edge science and innovation. From the different approaches available to measuring IDR, bibliometric indicators have experienced the greatest growth. Despite the frequent use of bibliometric measures of IDR in research and policymaking, their adequacy has...

This paper applied a literature-based discovery methodology utilizing citation networks and text mining in order to extract and represent shared terminologies found in disjoint academic literature on food security and the Internet of Things. The topic of food security includes research on improvements in nutrition, sustainable agriculture, and a pl...

This article reviews literature on manufacturing enterprise performance (MEP) and environmental sustainability (ES) to identify their commonalities and distinguishing factors; it is expected to help determine gaps and paths for future research. Topics are classified based on patterns in the citation networks of 7308 and 6275 MEP and ES articles, re...

Digitally dependent firms, which are linked to a large number of other firms with varying capabilities, are challenged on evaluating networks with which to engage. Empirically supported heuristic guidance can aid firms in identifying alliances to strengthen capability. We report a case study of firms linked to the Internet of Things (IoT) with a br...

Methodologies for literature-based discovery in their closed modality, aim to connect two disjoint literatures A and C by providing a list of B-terms from where hypotheses can be drawn. In this paper, we propose a method for representing B-terms as a network. Such representation further allows us to obtain shared themes and ease the exploration of...

Firms seeking to align with an emerging socio-technological paradigm for a future sustainable competitive advantage are faced with the decision of effectively positioning themselves within related business ecosystems. The positioning options broadly belong to assuming the functions of a platform, a supplier, a complementary, an intermediary or a co...

This study analyzes how characteristics in the careers of star researchers affect the outcomes of research and development (R&D), based on a case study in a Japanese semiconductor company. By analyzing the collaboration network of patent coinventors in the company, we observe that long-term exposition and collaboration with other high-achieving res...

https://authors.elsevier.com/a/1aawd15eiezy53 Energy storage technologies are a critical component of the rapidly growing global demand for reliable electric power supply. Consequently, researchers in both academia and industry have intensified their focus on enhancing electric power generation and distribution systems, publishing thousands of rel...

Business Ecosystem (BE) has been defined in multiple ways and has been used interchangeably, jointly and overlapping with innovation ecosystems (IE) and digital ecosystems (DE), making it difficult to differentiate, consolidate, utilize and grow the body of knowledge, both in academia and industry. We use text mining techniques to reveal overlappin...

Article: https://www.sciencedirect.com/science/article/pii/S0040162518312575 Robotics is a growing academic field that has received extensive social attention, where both promising and contested opinions can be found with regard to its applications. To understand commonalities and differences between social expectations and academic research, we a...

As robotics becomes ubiquitous, there is increasing interest in understanding how to develop robots that better respond to social needs, as well as how robotics impacts society. This is evidenced by the growing rate of publications on social robotics. In this article, we analyze the citation network of academic articles on social robotics to unders...

Funded research has been linked to academic production and performance. While the presence of funding acknowledgements may serve as an indicator of quality to some extent, we still lack tools to evaluate whether funding agencies allocate resources to novel and innovative research rather than mature fields. We address this issue in the present study...

In this study, we propose an unconnected component inclusion technique (UCIT) for patent citation analysis. Our method generates a cluster solution that includes unconnected and connected components of a direct citation network, enabling a more complete analysis of the technology fields. Case studies of Internet of Things-related technologies were...

[ES] Japón es un país clave en el desarrollo de robots humanoides ya que cuenta con importantes antecedentes como lo son las muñecas mecánicas karakuri del siglo XVII. Además posee un sólido imaginario dentro del mundo de la ficción donde los robots son amigos del ser humano, siendo Astroboy uno de sus mejores representantes. Por otra parte, el gob...
