As younger generations navigate a blended reality, their interaction with digital content and apps is marked by multitasking. Gender intersects with media and individual preferences, shaping how people navigate digital realms. This chapter investigates how young adults perceive personal digital experiences, analysing them based on various socio-demographic factors. Using a quantitative approach, a survey was conducted with 1,500 young adults in Portugal in October 2021. The sample was representative of the population distribution by sex, age and region. Statistical analysis revealed correlations between digital behaviours and socio-demographic factors such as gender, sexual orientation and parenthood status. Results indicated significant differences in agreement levels among different groups, highlighting areas such as online harassment, content creation, social interaction and digital intimacy. The findings challenge assumptions of homogeneity in generational technology usage and underscore the importance of considering diverse demographic perspectives in digital research. This chapter sheds light on the interplay between technology, identity and social connections, emphasising the relevance of gender in digital platform studies.

The purpose of this paper is to review cases of artificial reefs built through additive manufacturing (AM) technologies and analyse their ecological goals, fabrication process, materials, structural design features and implementation location to determine predominant parameters, environmental impacts, advantages, and limitations.

The review analysed 16 cases of artificial reefs from both temperate and tropical regions. These were categorised based on the AM process used, the mortar material used (crucial for biological applications), the structural design features and the location of implementation. These parameters are assessed to determine how effectively the designs meet the stipulated ecological goals, how AM technologies demonstrate their potential in comparison to conventional methods and the preference locations of these implementations.

The overview revealed that the dominant artificial reef implementation occurs in the Mediterranean and Atlantic Seas, both accounting for 24%. The remaining cases were in the Australian Sea (20%), the South Asia Sea (12%), the Persian Gulf and the Pacific Ocean, both with 8%, and the Indian Sea with 4% of all the cases studied. It was concluded that fused filament fabrication, binder jetting and material extrusion represent the main AM processes used to build artificial reefs. Cementitious materials, ceramics, polymers and geopolymer formulations were used, incorporating aggregates from mineral residues, biological wastes and pozzolan materials, to reduce environmental impacts, promote the circular economy and be more beneficial for marine ecosystems. The evaluation ranking assessed how well their design and materials align with their ecological goals, demonstrating that five cases were ranked with high effectiveness, ten projects with moderate effectiveness and one case with low effectiveness.

AM represents an innovative method for marine restoration and management. It offers a rapid prototyping technique for design validation and enables the creation of highly complex shapes for habitat diversification while incorporating a diverse range of materials to benefit environmental and marine species’ habitats.

This research focuses firstly on the impact of Social Media Influencer Marketing (SMIM) on the Economic Performance (EP) of Spanish wineries, and secondly on the mediating effect of Corporate Social Legitimacy (CSL) on this main relationship (SMIM-EP). Age, size and Protected Designation of Origin (PDO) membership are used to increase the precision of the cause-effect relationships examined.

The study proposes a conceptual model based on previous studies, which is tested using structural equations (PLS-SEM) with data collected from 196 Spanish wineries between September 2022 and January 2023.

The results reveal a positive and significant relationship between the development of SMIM and the EP of Spanish wineries, as well as the partial mediation of CSL in the SMIM-EP relationship.

The uniqueness of this study can be attributed to several factors. First, it enhances the understanding and knowledge of the benefits associated with SMIM development in the winemaking context. Second, no previous research has conducted an empirical study on the development of SMIM as a catalyst for EP in the context of Spanish wineries. Third, to the authors' knowledge, no previous study has examined the mediating role of CSL in the SMIM-EP relationship, thus representing an opportunity to advance scientific knowledge related to SMIM.
