Annual Research Symposium

Pterosaurs, a lineage of Mesozoic flying archosaurs, include the largest flying animals ever known. Quetzalcoatlus nortropi a Late Cretaceous representative, had a wingspan of over 10 m and likely weighed more than 200 kg. It presents a combination of features (large head, massive wingspan, shoulder height equivalent to an extant giraYe) that has led to ecological interpretations of it as a major predator in the North American Maastrichtian Biome, perhaps second to only Tyrannosaurus rex. Here we examine the probability of that from an energetics perspective. Despite the great wingspan of Quetzalcoatlus, the body length (gleno- acetabular distance) is relatively …

Non-Fungible Tokens (Nfts) And Copyright Law, Ochoa, Tyler T. Jan 2024

Non-Fungible Tokens (Nfts) And Copyright Law, Ochoa, Tyler T.

Santa Clara High Technology Law Journal

The concept of using non-fungible tokens (NFTs) to facilitate and authenticate sales of digital art dates back to 2014; but it took several years before the concept really captured public attention. Since copyright law governs the reproduction of works of art, including digital images, the connection to NFTs seems obvious. Yet, copyright law is only tangentially related to NFTs, for two reasons. First, buying an NFT does not, by itself, convey any rights to reproduce or display the work associated with that token. Instead, those rights are governed entirely by the contract that accompanies the sale. Second, minting and selling …


Human Reproductive Cloning, Heritable Genome Editing, And The Future Of Novel Reproductive Technologies, Macintosh, Kerry Lynn Jan 2024

Human Reproductive Cloning, Heritable Genome Editing, And The Future Of Novel Reproductive Technologies, Macintosh, Kerry Lynn

Santa Clara High Technology Law Journal

This Article compares human reproductive cloning (HRC) and heritable genome editing (HGE) to identify factors that encourage bans on novel reproductive technologies. HRC drew legislative opposition in part because it involved asexual reproduction and was incorrectly associated with copying. HGE and other technologies that involve sexual reproduction do not have those problematic qualities. HRC also became entangled with research in which human embryos were cloned to be harvested for their stem cells. HGE did not because scientists learned how to create and edit pluripotent stem cells without creating embryos. However, the legal history of HRC predicts that reproductive technologies strongly …

Alterity As A Mirror Of Identity: Primo Levi’S Self Representation In Other People’S Trades, Ilona Klein Jan 2024

Alterity As A Mirror Of Identity: Primo Levi’S Self Representation In Other People’S Trades, Ilona Klein

Faculty Publications

Primo Levi reveals much about himself in the fifty-one short essays of L’altrui mestiere (Other People’s Trades). This study analyzes L’altrui mestiere as the awareness of the “self” through the observation of “otherness” — other people, but also other living beings which are not human (mammalian animals and insects), others as minerals, and others as hypotheses, theories, writings, microcosmic or macrocosmic conceptions that Levi uses to weave a discourse of “alterity” as a mirror of “identity.” L’altrui mestiere’s narrative pattern revolves around contrasts and comparisons between the familiar and the unfamiliar, the canny and the uncanny, the …
