Background: Legalizing medical and recreational cannabis and decriminalizing this substance may have unanticipated effects on traffic safety. The present study aimed to assess the impact of cannabis legalization on traffic accidents. Methods: A systematic review was carried out following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) declaration of the articles included in the Web of Science (WoS) and Scopus databases. The number of papers included in the review was 29. Results: The results show that in 15 papers, there is a relationship between the legalization of medical and/or recreational cannabis and the number of traffic accidents, while in 5 papers, no such relationship is observed. In addition, nine articles indicate a greater number of risk behaviors related to driving after consumption, identifying young, male, and alcohol consumption together with cannabis as the risk profile. Conclusions: It can be concluded that the legalization of medical and/or recreational cannabis has negative effects on road safety when considering the number of jobs that affect the number of fatalities.

Although fully automated vehicles (SAE level 5) are expected to acquire a major relevance for transportation dynamics by the next few years, the number of studies addressing their perceived benefits from the perspective of human factors remains substantially limited. This study aimed, firstly, to assess the relationships among drivers’ demographic factors, their assessment of five key features of automated vehicles (i.e., increased connectivity, reduced driving demands, fuel and trip-related efficiency, and safety improvements), and their intention to use them, and secondly, to test the predictive role of the feature’ valuations over usage intention, focusing on gender as a key differentiating factor. For this cross-sectional research, the data gathered from a sample of 856 licensed drivers (49.4% females, 50.6% males; M = 40.05 years), responding to an electronic survey, was analyzed. Demographic, driving-related data, and attitudinal factors were comparatively analyzed through robust tests and a bias-corrected Multi-Group Structural Equation Modeling (MGSEM) approach. Findings from this work suggest that drivers’ assessment of these AV features keep a significant set of multivariate relationships to their usage intention in the future. Additionally, and even though there are some few structural similarities, drivers’ intention to use an AV can be differentially explained according to their gender. So far, this research constitutes a first approximation to the intention of using AVs from a MGSEM gender-based approach, being these results of potential interest for researchers and practitioners from different fields, including automotive design, transport planning and road safety.

El objetivo de la presente investigación es analizar la evolución de la colaboración científica en la psicología española a través de trabajos firmados por un autor o autora perteneciente a una institución española de psicología entre 1970 y 1989. Se analizaron un total de 2891 trabajos publicados en 29 revistas de psicología entre los años 1970 y 1989, analizando la colaboración científica a través del estudio de redes mediante el programa UCINET y el software Netdraw. Los resultados indican que a lo largo de los años se produce un aumento del número de trabajos, autores y firmas, así como de la colaboración científica, siendo en el periodo entre 1985 y 1989 cuando los trabajos en coautoría superan al número de trabajos firmados por un solo autor. Se muestra que el número de autores, así como de los grupos de colaboracion aumentan a lo largo de los años estudiados. Se puede concluir que es en la segunda mitad de la década de los años 80 cuando se produce un aumento considerable de la colaboración científica en la psicología española. The objective of this research is to analyse the evolution of scientific collaboration within Spanish psychology through papers signed by an author who belonged to a Spanish institution of psychology between 1970 and 1989. We analysed a total of 2891 papers published in 29 journals of psychology between 1970 and 1989, examining the scientific collaboration through network analysis, using the UCINET program and Netdraw software. The results indicated that there has been an increased number of papers, authors and signatures over the years, as well as an increased scientific collaboration. Between 1985 and 1989, co-authored papers overcame single-author papers. It is shown that the number of authors, as well as of collaboration groups, increased over the years under study. It can be concluded that it was in the second half of the 1980s when scientific collaboration within Spanish psychology increased considerably.

El objetivo del presente trabajo es profundizar en los hábitos de publicación de los miembros de los comités editoriales de las revistas iberoamericanas de psicología recogidas en la Web of Science (WoS) entre los años 2013 y 2015 a través de diferentes indicadores bibliométricos. Los resultados revelan una disparidad en la participación de los miembros del comité editorial de una revista a otra, un menor tiempo de aceptación de los artículos y un mayor número de citas, principalmente en las bases de datos Web of Science y BIOSIS, por parte de los miembros del comité editorial. Muchos de los miembros de los equipos editoriales son investigadores de reconocido prestigio en su disciplina, por lo tanto, su participación a través de la publicación de artículos en las revistas de las que forman parte es un aval de éxito para la publicación, dado el número de citas que reciben sus trabajos.

El objetivo del presente estudio es analizar la producción científica en psicología clínica de los investigadores que trabajan en instituciones españolas desde una perspectiva de género. Se obtuvieron todos los trabajos publicados en la Web of Science desde la subcategoría “psychology clinical”, entre los años 1971 y 2020. Estas cinco décadas de estudio muestran un total de 3784 trabajos. Se observan diferencias en la publicación de trabajos en psicología clínica en el tiempo estudiado. De una exigua representación femenina inicial a una mayoría de mujeres en la actualidad. Los cambios en la producción también son notorios, pasando de un índice de colaboración de 1.60 autores por trabajo en los años iniciales a un índice de colaboración de 4.77 en el año 2020. No obstante, se hace necesario seguir ahondando en políticas públicas y científicas que permitan llegar a un verdadero equilibrio entre géneros.

Although developing countries represent a minimal percentage of the world's scientific production with impact, it is necessary to analyze and study them to appreciate their research policies, publication rates and collaborations. For this study, we have selected all the countries that, according to the Human Development Report 2020, have a research and development expenditure below 0.8, which puts 168 countries in the focus of analysis. Focusing on the articles and review articles that these countries have obtained in the 11 categories that exist in Web of Science (SCI, SSCI and ESCI collections) on psychology, all articles with an impact factor in the years 2017 to 2021 have been selected. In total, 21337 articles were extracted, 62% of which were produced in South America and Asia. The highest number of papers have been published in the categories "Psychology Multidisciplinary" (33.7%) and "Psychology Clinical" (16.0%). Journals indexed in developing countries tend to have a more significant impact within their own continent, and the scientific collaboration networks they maintain are predominantly within the same continent. This leads us to the conclusion that scientific production and dissemination in developing countries are severely constrained, possibly due to social, economic, and political factors.
