Modern pinnipeds distributed along the coasts of continental South America consist almost entirely of otariids (sea lions and fur seals). In contrast, phocids (true seals) are present only on the southernmost extreme of Chile. This recent biogeographic pattern is consistent with the zooarchaeological record (∼8–2 ka), but it is incompatible with the(More)
Marine mammal mass strandings have occurred for millions of years, but their origins defy singular explanations. Beyond human causes, mass strandings have been attributed to herding behaviour, large-scale oceanographic fronts and harmful algal blooms (HABs). Because algal toxins cause organ failure in marine mammals, HABs are the most common mass stranding(More)

Partial remains of a titanosaur sauropod collected in the Tolar Formation (Upper Cretaceous) at the Atacama Desert (Antofagasta Region), northern Chile, is described, and a new species, Atacamatitan chilensis gen. et sp. nov., is erected. The material consists mainly of dorsal and caudal vertebrae, part of a humerus and a femur. The presence of a titanosaur(More)
As organizations become more process centered, business process modeling and analysis techniques are becoming critical for decision making. However, most modeling tools have important limitations that make them unsuitable for performing advanced analysis, such as the almost exclusive focus on the control domain. An even more severe limitation is the(More)
In today’s world the oil and gas industries play major roles in energy consumption. Nations depend heavily on these resources despite their major disadvantage: They are not renewable. As the demand for renewable energy increases, it is necessary to identify new energy sources and to invent ways of harvesting these energies by designing new systems. The(More)
This paper extends the concept of digital literacy and applies it to Making. Through case descriptions, we contribute an understanding of how children can become or fail to become individuals literate in Making within a formal learning context. Our analysis draws from video recordings and other data sources of two 4th grade classrooms in which the students,(More)
