Is There Intentionality in Boredom? Phenomenological Perspectives
(Taylor & Francis, 2025-06-04) López Sáenz, Mª Carmen; Elpidorou, Andreas; Ros Velasco, Josefa
The phenomenology of boredom is usually identified with that of Martin Heidegger. This chapter reveals other important phenomenological contributions to the understanding of this phenomenon, following the guiding thread of intentionality, the central concept of this philosophical movement. Although the affective experience of boredom seems to lack intentionality and meaning, this work will show that this is not always the case. In order to demonstrate this, the study will explore the different modalities of intentionality throughout the history of phenomenology, particularly within current phenomenological research, and their relation to the lived experience of boredom. The chapter focuses on the meaning of this common experience and affirms the importance of a phenomenology of boredom in order to maintain the dialectical tension of existence.

The Role of Fermented Vegetables as a Sustainable and Health-Promoting Nutritional Resource
(MDPI, 2024-11-23) Borrego Ruiz, Alejandro; González Domenech, Carmen María; Borrego, Juan J.
The increasing global burden of morbidity and mortality from chronic diseases related to poor diet quality, coupled with the unsustainable depletion of vital planetary resources by current food production systems, threatens future food security and highlights the urgent need to transition to high-quality plant-based diets as a viable solution to mitigate economic, health, and environmental challenges. Taking into consideration the significant role that fermented vegetables may play as a sustainable, healthy, long-lasting, and plant-based nutritional resource, this narrative review analyzes their production and benefits. For this purpose, the mechanisms of the fermentation process are explored, along with the importance of probiotic cultures in plant-based fermented foods, and with the implications of fermentation on food safety within the broader framework of low-impact, organic, plant-derived nutrition. Additionally, the health benefits of fermented vegetables and probiotics are examined, including their effects on mental health. Vegetable fermentation is a versatile method for enhancing food preservation, nutritional quality, and safety. This ancient practice prolongs the shelf life of perishable items, reduces the toxicity of raw ingredients, and improves digestibility. Specific starter cultures, particularly lactic acid bacteria, are essential for controlling fermentation, ensuring safety, and maximizing health benefits. Fermented vegetables, rich in probiotics, support gut health and immune function. Emerging research indicates their potential to alleviate adverse mental health symptoms such as stress and anxiety, highlighting their significance in modern dietary guidelines and chronic health management.

New information on the anatomy and paleobiogeographic and stratigraphic distributions of the British basal turtle Plastremys lata (Helochelydridae) based on its most complete skeleton (lower Albian, Spain)
(ELSEVIER, 2025-06-06) Pérez García, Adán; Espílez, E.; Mampel, L.; Cobos, A.
The synchronous and sympatric presence of two helochelydrids is reported here for the first time for the Spanish Municipality of Ariño (Teruel Province), where the most complete skeletons from that group had been found for the European record. The presence of two members of this lineage of basal turtles has been documented in very few localities worldwide, and until now consisted of isolated and fragmented remains. Although the lower Albian Aragochersis lignitesta is exclusively documented in this Spanish paleontological area, its material is here identified as the oldest occurrence for the British Plastremys lata, extending the paleobiogeographic distribution range for that taxon. New material from Ariño includes a partial skeleton, as well as isolated remains of several individuals. Their analysis not only shows intraspecific variability, but also documents several anatomical elements previously unknown for Plastremys lata, which was only known from shell remains. Furthermore, the status of the first Mesozoic turtle taxon defined for the Spanish record (i.e., the hitherto problematic ‘Trachyaspis turbulensis’, also from the lower Albian of Teruel) is examined and its holotype, whose original anatomical attribution is here revised, is reattributed to Plastremys lata.
