El gobierno de las aguas por instituciones comunitarias. La desmunicipalización en la acequia de Escalona (1591-1783)
2018
La historiografía viene proponiendo un doble modelo en lo que concierne a la imbricación de las instituciones políticas locales en el gobierno de las aguas y la gestión hidráulica realizada: acequias sometidas a control municipal, en las que correspondía a los ediles del consitorio adoptar decisiones relevantes y ejercer jurisdicción, frente a una minoría exigua de macrosistemas en los que los colectivos de regantes realizaron una gestión autónoma. En otros trabajos he cuestionado esta dicotomía en l’Horta, recalcando que la imbricación de instituciones municipales y oficiales de la monarquía fue allí relevante (Peris, 1992, 2003a, 2014a, 2014b). El presente artículo, que combina referencia…
Visually Induced Motion Sickness on the Horizon
2020
Visually induced motion sickness is an unpleasant but common side-effect of many simulations and VR-applications. We investigated whether an earth-fixed reference frame provided in the simulation is able to reduce motion sickness. To do so, we created a moving starfield that did not contain any indicators of the spatial orientation of the observer. As the observer was simulated to move through the randomly oscillating starfield, a time-to-contact task had to be carried out. Two colored stars on collision course with each other had to be spotted, then they disappeared and the time of their collision had to be judged. Eye-movements, task performance, and motion sickness were recorded. This co…
The Quantified Athlete: Associations of Wearables for High School Athletes
2018
The adoption of wearable technology in competitive sports can be an advantage to performance and training. Athletes who use personalised data to quantify their performances with the possibilities of sharing with others may use wearables to reinforce the athletic identity. Despite these changes, few studies have actually examined the associations between wearables and developing athletes in their quest for professional sports. Student athletes (n = 437, age = 17y) still in high schools completed a web-based survey about their professional aspirations, athletic identity, and the association with wearables. Wearables were measured by ownership and usage of apps, fitness trackers, or sports wat…

Montlivaltia multiformis Toula (Scleractinia) from the Aptian of the Prebetic Domain (SE Spain)
2021
Montlivaltia multiformis Taula (Scleractinia, Faviina, Montlivaltidae), formerly reported from the Carpatho Balkanic domain is described from Lower Aptian beds of the Prebetic Domain (SE Spain). Taxonomic attributes include the organisation of radial elements, septal trabeculae, carinae and endothecal elements while the external morphology of the coralla is fairly variable. The sedimentological context suggests a circalittoral environment also supported by palaecological features of the surrounding fauna. Owing to its stratigraphic position in the Carpatho-Balkanic region and in Spain, Montlivaltia multiformis appears as a potential marker for both shallow carbonate or outer shelf settings …
Presence of Naraoia Walcott, 1912 (Nektaspida, Arthropoda) in the middle Cambrian of Europe (Murero, NE Spain).
2018
The genus Naraoia Walcott, 1912, a Burgess Shale-type fossil known from the lower and middle Cambrian of British Columbia (Canada), Idaho and Utah (USA), as well as from Yunnan and Guizhou provinces (China), is now reported from the middle Cambrian of Murero (Zaragoza, Spain), which is the first record in the Acadobaltic province. The only fragmented specimen found is determined as Naraoia sp., its age being Pardailhania multispinosa Zone (Drumian Stage). This new datum reinforces the hypothesis of the existence of a cosmopolitan faunal substrate in early Cambrian times, which is to some extent refl ected in the mid Cambrian by faunal groups of low evolutionary potential as the family Narao…
A database of Triassic conodonts from a comprehensive revisión of literature
2013
The revision of a comprehensive amount of bibliography has made possible the development of a database containing the stratigraphic ranges of the conodont species from the uppermost Permian and the Triassic, with a total of 336 species in 52 genera. This database is aimed at biostratigraphy and studies related to biological, evolutional and palaeodiversity dynamics. La revisión de una amplia cantidad de bibliografía ha hecho posible el desarrollo de una base de datos en la que figuran los rangos estratigráficos de las especies de conodontos presentes desde el Pérmico superior y el Triásico, con un total de 336 especies y 52 géneros. Esta base de datos está dirigida a la bioestratigrafía y a…
Fragmentary remains of Odontocetes (Cetacea, Mammalia) from the Miocene of the Lower Tagus Basin (Portugal)
2021
This first systematic account of the scarcely studied Miocene cetaceans from Portugal describes 17 previously unpublished odontocete specimens from the Lower Tagus Basin. In spite of their fragmentary nature, at least a familial assignment was accomplished for most, and some were even tentatively ascribed to known genera: the Physeteridae are represented only by isolated teeth of “ Scaldicetus ” type; the Platanistidae by a tympanic not definitely assigned to a particular genus; the Eurhinodelphinidae by a lumbar vertebra and an atlas, both only tentatively referred to this family; and the Kentriodontidae comprise the most diversified forms, including rostral and mandibular fragments of a k…
Sella, A NEW NAME FOR THE GENUS Linaresia EL KADIRI, 1992 (NASSELLARIA, RADIOLARIA) PREOCCUPIED BY COPEPOD CRUSTACEANS (LAMIPPIDAE, MAXILLOPODA)
2021
The aim of this short note is to create a new name of this genus since the original name Linaresia proved to pre-exist in the paleontological literature ( Linaresia de Zulueta, 1908, Family Lamippidae, Copepod crustaceans, and Linaresia Gonzalez-Donoso, 1968, Family Gavelinellidae, Agglutinated Foraminifera). The new name created for the above mentioned radiolarians is: Sella . This name derives from an arbitrary combination of letters (International Code of Zoological Nomenclature). The type species of Sella is S. beniderkoulensis by original designation (El Kadiri, 1992).
