Face à globalização, ao mundo em rede, à revolução tecnológica em curso, aos conflitos geopolíticos, aos confrontos geoeconómicos e à destruição dos ecossistemas, as crises assumem efeitos cada vez mais graves e abrangentes à escala global. Refletiremos sobre os diferentes conceitos e tipologias de crise, sobre os sistemas e subsistemas nacionais de gestão de crises e sobre a necessidade de consolidar uma abordagem holística que confira mais resiliência e coerência na prevenção e resposta a crises. Sob o pano de fundo da recente invasão da Ucrânia, analisaremos a incerteza, riscos e potenciais efeitos em cadeia nos planos geopolítico e económico de crises complexas na contemporaneidade.

This paper aims to identify the influence of lean office principles in criminal investigations deployed as special operations. The research has a descriptive-exploratory character, a quantitative approach and Survey method. whose data collection was carried out through an online questionnaire. The valid sample consisted of 139 responses from police officers working in criminal investigations. Data analysis was performed using exploratory factor analysis and multiple linear regression. The special investigation process has been continuously improved since the 1980s. The results suggest that the efficiency in this kind of process is positively influenced by the adoption of authorized production in teams with greater power and responsibility, less supervision interference, and by the identification and elimination of waste, meaning activities that do not add value to the end user. Team size, physical office organization, and leadership rotation do not significantly influence efficiency. Therefore, organizations can seek lean police investigation as a way of improving processes.

El crecimiento sin precedentes del comercio electrónico en México causado por la pandemia de COVID-19 se convirtió en un desafío para los minoristas en términos de gestión de quejas. Si bien los estudios de marketing han estudiado el uso de las redes sociales en este contexto, hay poca investigación desde la perspectiva del consumidor para comprender cómo la comunicación digital ha transformado la capacidad del consumidor para obtener compensación. Este estudio utiliza el marco teórico del boca a boca electrónico (eWOM) y el comportamiento de quejas para explorar los reclamos en línea de los consumidores durante la pandemia. Mediante el análisis de datos de Twitter a gran escala en 2019 y 2020 (un poco más de 95.000 tuits), se cuantifica la frecuencia de las denuncias para mostrar la evolución de este fenómeno para siete de los principales minoristas del país a través de un análisis cualitativo. Los resultados indican que la mayoría de los minoristas presentan una tendencia similar en términos de cantidad y tipo de quejas; sin embargo, algunos de ellos parecen haberse adaptado más rápidamente. Los mercados electrónicos, por el contrario, presentan problemáticas distintas. En general, los temas relacionados con la entrega, la devolución y el servicio estuvieron entre los más tuiteados. Las quejas también sugieren que la falta de conocimiento sobre los procedimientos y la información insuficiente son dimensiones que requieren atención. Al comparar las quejas formales presentadas por los consumidores con su uso de Twitter, el estudio concluye que utilizan esta red para quejarse.

Social media are one of the tools most used by fact-checking organizations to disseminate their verifications. Instagram has gained prominence and relevance in recent years, but studies on the activity of verifiers on this network have not. This research seeks to characterize the activity of Ibero American fact-checkers on Instagram based on the content that has generated the highest interaction rate. We conducted a quantitative analysis of the 2021 posts by the fact-checkers belonging to the International Fact Checking Network (IFCN) with the greatest interaction, with a resulting sample of 301 posts. The results show that fact-checkers maintained a fairly stable publication frequency throughout the year; considering the posts’ intention, they published mainly fact-checks (72.8%) and, regarding the theme, political content (39.5%). As for the subject, posts on racism are the ones that obtain a better interaction ratio (12%) while in terms of format, the album reaches a substantially higher ratio than images or videos.

#MeToo is one of the feminist movements driven by the digital and with glocal expression. Turned viral through Twitter, it quickly gained visibility in traditional media, bringing to the public sphere the discussion of topics related to sexual harassment and violence. Using the public expression of the #MeToo movement in the Portuguese traditional media between 2017 and 2022, and based on a qualitative methodology anchored in a thematic analysis of 91 opinion articles of the newspapers Expresso and Público, this paper aims to comprehend the particularities of the Portuguese context around #MeToo issues and analyze the themes that were highlighted in these spaces. Three major themes arise: sexual harassment and violence, questioning (re)victimization and normalization, and the Ambivalence of feminisms in the #MeToo movement. From our findings, the emergence of contradictory discourses about the movement that served to both discredit it and raise public awareness of the problems of sexual harassment and violence stands out. In conclusion, opinion articles have the power to both influence the crystallization of specific positions and the change of attitudes and behaviors in the public sphere due to the authority and legitimacy of those who write opinion pieces in the newspapers and have the ability to thematize the public sphere.

This work investigates a collaborative learning experience, developed through the Linkedin social network with undergraduate university students from Communication and Digital Communication. To learn about the activity produced in the network, as well as the skills acquired by the students and their assessment of this task, a double qualitative and quantitative study has been carried out. Respectively, a content analysis spreadsheet and a structured interview have been used as measurement instruments. The results show a high level of participant involvement, who claim to have improved not only their knowledge in social networks, marketing and advertising, but also their skills as digital content curators. In addition, the students found the activity inspiring and consider its application viable in the majority of the modules of their course.

Con el auge del aprendizaje móvil, uno de los principales retos de la Educación superior consiste en la formación de una ciudadanía crítica y activa, capaz de participar en el entorno. De esta manera, y gracias a la incorporación de nuevas herramientas basadas en la geolocalización y la realidad aumentada geolocalizada, es posible el desarrollo de actividades de enseñanza-aprendizaje en cualquier contexto y en cualquier lugar. En este trabajo, se presenta una revisión sistemática de la literatura para recoger los principales hallazgos sobre el uso de las aplicaciones de geolocalización y realidad aumentada geolocalizada durante las salidas escolares en Educación Superior. La búsqueda se ha realizado a partir de las publicaciones incluidas en las base de datos  “Web of Science” y “Scopus” durante el período 2010-2021. Al aplicar los criterios de selección y calidad, se han identificado un total de 15 estudios como muestra final. Los resultados obtenidos demuestran un interés creciente por el desarrollo de nuevas aplicaciones de geolocalización y realidad aumentada geolocalizada adaptadas al ámbito educativo de las Ciencias sociales. Entre las potencialidades de la geolocalización para el desarrollo de salidas escolares, podemos mencionar  el aumento de la motivación, el interés y la participación del alumnado en el proceso de enseñanza-aprendizaje, así como el desarrollo de las competencias espaciales.
