A tall rostral hook in a medieval horse premolar tooth
Development of dental abnormalities due to improper occlusal wear is common among modern domestic horses. This phenomenon often is attributed to jaw conformation. Rostral mandibular hooks may develop in horses with underjet or mandibular prognathism, a condition where the lower jaw protrudes forward, beyond the upper jaw. Less abrasive diet, free of phytoliths and matrix-like plant fibers, also may promote enamel and focal overgrowths of equine dentition. Here we report a rostral mandibular hook in a lower premolar tooth of a medieval horse, found in a spring deposit in Levanluhta, Osthrobothnia, Finland. To our knowledge, this is the first such report from a medieval horse. (C) 2017 Elsevier Inc. All rights reserved.Peer reviewe
Implication of two new paradigms for futures studies
The paper considers the emergence of two recent perspectives in futures work. One is evolutionary futures studies. The other is critical futures studies. After describing aspects of
each, the paper considers them as alternative rival paradigms in relation to criteria that include: the role of the human being as a subject, the role of interpretation and differences in methodological premises. It concludes that both have contributed to the development of futures methods but that a number of theoretical and methodological problems still remain unsolved
Recapturing the sounds and sonic experiences of the hunter-gatherers at Ajvide, Gotland, Sweden (3200‒2300 cal BC)
The rich and well-preserved osteological material from the archaeological complex of Ajvide, Gotland (3200‒2300 cal BC), provides favorable conditions for studying prehistoric sounds and soundscapes. Archaeological excavations at the site have uncovered tubular bone artifacts and concentrations of animal tooth pendants that resemble whistles and rattles, the earliest types of sound instruments. The remains of hunted animals, such as seals, boars, dogs and birds, provide a lively picture of the species that were present in the environment. This article aims to evoke the sonic experiences of the people utilizing the site of Ajvide and explore how these hunter-gatherers constructed and responded to their sonic environment. The results of the osteological, organological and soundscape analyses are presented in the form of a scholarly text, samples of studio and field recordings, and a soundtrack that fuses the results together into a nine-minute piece of sound art.Peer reviewe
