This study explores temporal interaction patterns within the Community of Inquiry (CoI) framework using Moodle activity logs from two online courses for older adults. Both courses shared identical content and structure, but differed in facilitation: case (a) involved a single instructor (n = 27), while case (b) included peer facilitators (n = 45). A total of 4,276 log entries were analysed as proxy variables for teaching, social, and cognitive presence. These were converted into time series and examined through cross-correlation analysis with a three-day lag. The results sugest that accessing the course guide and attending synchronous sessions are key triggers for cognitive and social engagement. Alternating patterns were also observed between individual content processing and social interaction. These findings provide valuable insights into the temporal dynamics of online learning interactions, particularly for instructional planning and process-oriented research.

La adopción de los Sistemas de Gestión del Aprendizaje (LMS, por sus siglas en inglés) plantea desafíos significativos en ciberseguridad que deben ser estudiados desde el ámbito científico-académico. Por ello, este artículo hace un estudio bibliométrico sobre esta área, que refleja la relevancia actual de la misma en el ámbito científico-académico, señalando el número de artículos publicados sobre esta temática, las fuentes de publicación de estos artículos, sus autores, la procedencia de estos autores, las tendencias investigativas y el impacto de estos artículos dentro del campo investigativo. De esta manera, este análisis permite evidenciar que se está ante un campo de investigación que está comenzando a emerger y que tiene un potencial significativo para futuras líneas de trabajo, profundizando en el desarrollo de marcos pedagógicos y de competencias en ciberseguridad aplicados a los LMS y fomentando la colaboración interdisciplinar entre el ámbito tecnológico y el educativo.

The use of the online channel for the purchase of food products is increasing, which not only creates new opportunities for companies and businesses, but also poses great challenges. This study aimed to identify the factors related to these challenges that influence the use of the online channel for the purchase of food products in Spain. Through a bibliographic review and a Delphi study with experts, 26 factors were identified and grouped into four contexts: technology, marketing strategies, buyer convenience, and security and reliability. This identification of factors can be of great value in improving the sales of companies or businesses in the food sector that already use the online channel for the sale of their products or intend to use it for this purpose in the future; furthermore, it will help these companies or businesses to implement sales strategies that will truly satisfy the needs of potential consumers in Spain.
