Show moreTaxonomic identification of whale bones found during archaeological excavations is problematic dueto their typically fragmented state. This difficulty limits understanding of both the past spatio-temporal distributions of whale populations and of possible early whaling activities. To overcomethis challenge, we performed zooarchaeology by mass spectrometry on an unprecedented 719archaeological and palaeontological specimens of probable whale bone from Atlantic Europeancontexts, predominantly dating fromca3500 BCE to the eighteenth century CE. The results showhigh numbers of Balaenidae (many probably North Atlantic right whale (Eubalaena glacialis)) andgrey whale (Eschrichtius robustus) specimens, two taxa no longer present in the eastern NorthAtlantic. This discovery matches expectations regarding the past utilization of North Atlantic rightwhales, but was unanticipated for grey whales, which have hitherto rarely been identified in theEuropean zooarchaeological record. Many of these specimens derive from contexts associated withmediaeval cultures frequently linked to whaling: the Basques, northern Spaniards, Normans,Flemish, Frisians, Anglo-Saxons and Scandinavians. This association raises the likelihood that earlywhaling impacted these taxa, contributing to their extirpation and extinction. Much lower numbersof other large cetacean taxa were identified, suggesting that what are now the most depletedwhales were once those most frequently used. Show less

Show moreBackground: Alcohol is often consumed in social contexts. An emerging social context in which alcohol is becoming increasingly apparent is social media. More and more young people display alcohol-related posts on social networking sites such as Facebook and Instagram. Objective: Considering the importance of the social aspects of alcohol consumption and social media use, this study investigated the social content of alcohol posts (ie, the evaluative social context and presence of people) and social processes (ie, the posting of and reactions to posts) involved with alcohol posts on social networking sites. Methods: Participants (N=192; mean age 20.64, SD 4.68 years, 132 women and 54 men) gave researchers access to their Facebook and/or Instagram profiles, and an extensive content analysis of these profiles was conducted. Coders were trained and then coded all screenshotted timelines in terms of evaluative social context, presence of people, and reactions to post. Results: Alcohol posts of youth frequently depict alcohol in a positive social context (425/438, 97.0%) and display people holding drinks (277/412, 67.2%). In addition, alcohol posts were more often placed on participants’ timelines by others (tagging; 238/439, 54.2%) than posted by participants themselves (201/439, 45.8%). Furthermore, it was revealed that such social posts received more likes (mean 35.50, SD 26.39) and comments than nonsocial posts (no people visible; mean 10.34, SD 13.19, P<.001).Conclusions: In terms of content and processes, alcohol posts on social media are social in nature and a part of young people’s everyday social lives. Interventions aiming to decrease alcohol posts should therefore focus on the broad social context of individuals in which posting about alcohol takes place. Potential intervention strategies could involve making young people aware that when they post about social gatherings in which alcohol is visible and tag others, it may have unintended negative consequences and should be avoided.
