The fuel-cell electric vehicle (FCEV) has been defined as a promising way to avoid road transport greenhouse emissions, but nowadays, they are not commercially available. However, few studies have attempted to monitor the global scientific research and technological profile of FCEVs. For this reason, scientific research and technological development in the field of FCEV from 1999 to 2019 have been researched using bibliometric and patent data analysis, including network analysis. Based on reports, the current status indicates that FCEV research topics have reached maturity. In addition, the analysis reveals other important findings: (1) The USA is the most productive in science and patent jurisdiction; (2) both Chinese universities and their authors are the most productive in science; however, technological development is led by Japanese car manufacturers; (3) in scientific research, collaboration is located within the tri-polar world (North America-Europe-Asia-Pacific); nonetheless, technological development is isolated to collaborations between companies of the same automotive group; (4) science is currently directing its efforts towards hydrogen production and storage, energy management systems related to battery and hydrogen energy, Life Cycle Assessment, and greenhouse gas (GHG) emissions. The technological development focuses on technologies related to electrically propelled vehicles; (5) the International Journal of Hydrogen Energy and SAE Technical Papers are the two most important sources of knowledge diffusion. This study concludes by outlining the knowledge map and directions for further research.

This study analyzes Twitter’s contribution to green energy. More than 200,000 global tweets sent during 2020 containing the terms “green energy” OR “greenenergy” were analyzed. The tweets were captured by web scraping and processed using algorithms and techniques for the analysis of massive datasets from social networks. In particular, relationships between users (through mentions) were determined according to the Louvain multilevel algorithm to identify communities and analyze global (density and centralization) and node-level (centrality) metrics. Subsequently, the content of the conversation was subject to semantic analysis (co-occurrence of the most relevant words), hashtag analysis (frequency analysis), and sentiment analysis (using the VADER model). The results reveal nine main communities and their leaders, as well as three main topics of conversation and the emotional state of the digital discussion. The main communities revolve around politics, socioeconomic issues, and environmental activism, while the conversations, which have developed mostly in positive terms, focus on green energy sources and storage, being aligned with the main communities identified, i.e., on political, socioeconomic, and climate change issues. Although most of the conversations have been about socioeconomic issues, the presence of leading company accounts was minor. The main aim of this work is to take the first steps toward an innovative competitive intelligence methodology to study and determine trends within different scientific fields or technologies in society that will enable strategic decisions to be made.

Purpose: The main objective of this research is to design an Organizational Culture Transformation Model (OCTM) prototype, in order to enable a High Performance Organization (HPO).Design/methodology/approach: There are three main processes involved in the methodology. Two of them, the definition of the main OCTM work elements as an initial hypothesis based on a work environment approach and the scientific visualization of the key Organizational Culture research hubs through the analysis of the main topics in research publications, flow in parallel. Subsequently, at a certain point, both of these merge in a third process, the OCTM prototype definition. This last process, will deliver the Organizational Culture Transformation Model prototype, which essentially constitutes the main objective of the study.Findings: As result of the methodology, an Organizational Culture Transformation Model prototype has been developed.Originality/value: The resulting model will serve as a reference framework for those companies that wish to conduct an in-depth re-structuring of their operations, focusing it on their human capital.

Este trabajo investiga las razones y los beneficios esperados por las empresas españolas cotizadas no financieras para divulgar información sobre riesgos, así como las posibles motivaciones para no hacerlo. Investiga la situación actual de la divulgación de riesgos, pero también mira hacia adelante y estudia cómo será ésta en un futuro próximo. A la vista de un entorno cada vez más demandante de información, busca ideas que permitan mejorar esta práctica. Con el objetivo de conseguir los puntos de vista de las partes implicadas (preparadores y usuarios de la información de riesgos) y obtener una opinión consensuada entre ellos, realizamos un estudio Delphi. El grupo de expertos estuvo formado por veintidós personas, trece directores de auditoría interna de empresas españolas cotizadas no financieras, cinco analistas financieros y cuatro académicos. Realizamos tres rondas de preguntas entre los meses de enero y julio de 2017.El estudio concluye, entre otras cosas, que la demanda de información sobre riesgos aumentará en los próximos años, que los beneficios derivados de la divulgación compensan a las empresas de cualquier coste asociado a ella, y que el legislador debe desarrollar más disposiciones legales que aseguren mayor claridad y consistencia de la información, y mayor comparabilidad entre compañías. This paper researches the reasons and expected benefits of Spanish non-financial listed companies for disclosing risk information as well as the possible motivations for not doing so. It investigates the current situation of risk disclosure but also looks forward and studies what it will be like in the near future. In view of an increasingly information demanding environment, it looks for ideas for improving the risk disclosure practice.With the objective of gathering insights from the parties involved (preparers and users of risk information) and getting an agreed view among them, we conducted a Delphi study. The group of experts was made up of twenty-two people, thirteen internal audit directors from Spanish non-financial listed companies, five financial analysts and four scholars. We ran three rounds of questions between the months of January and July of 2017. The study concludes, among other findings, that the demand for risk disclosure will increase in coming years, that the benefits of disclosing offset any kind of associated costs, and that the policy maker should develop more legal provisions to ensure greater clarity and consistency of risk information and more comparability among companies.
