Attitude reports without complementation: The case of Amahuaca

Classic analyses of propositional attitude reports assume that attitude verbs compose with a clausal argument that expresses a proposition. I use original fieldwork data to demonstrate that Amahuaca (Panoan; Peru) attitude reports involve high adjunct switch-reference clauses rather than clausal complements to an attitude verb. This structure raises issues for the traditionally assumed compositional semantics of attitude reports. I present two potential analyses that do not require the verb to compose directly with a complement CP, ultimately arguing in favor of an analysis that aligns with proposals by Kratzer (2006) and Moulton (2015) that the internal arguments of attitude verbs are individuals with propositional content. Amahuaca therefore provides novel empirical support for this approach to the semantics of attitude reports

Against non-reference-tracking theories of switch-reference

Recent accounts of switch-reference have suggested that direct reference tracking is not involved. Instead, these accounts have sought to derive patterns of switch-reference from other independently attested phenomena such as control and coordination. What these diverse theories have in common is the prediction that same subject constructions should contain only one instance of a subject DP. I present evidence from Amahuaca showing that overt DP subjects can appear in both clauses in same subject constructions, contra the predictions of these non-reference-tracking theories. However, there is also evidence that Amahuaca same subject marked clauses are structurally smaller than different subject marked clauses. This size asymmetry is predicted by non-reference-tracking accounts but not by traditional direct reference-tracking theories. Thus while the Amahuaca data provide evidence against non-reference-tracking theories of switch-reference, they suggest that direct reference-tracking accounts must also be modified in order to account for the full range of data

Agreement, case, and switch-reference in Amahuaca

This dissertation probes the nature of the syntactic operation of Agree through the lens of the morphosyntax of Amahuaca, an endangered Panoan language of the Peruvian Amazon. I take as my empirical focus two interrelated case studies in Amahuaca syntax: 1) the split ergative case system, and 2) the extensive switch-reference system. In the domain of case, I argue that overt ergative case morphology in Amahuaca expones agreement of the transitive subject with multiple functional heads. This leads to a distinction between the features needed for abstract ergative case (agreement only with v), and the features needed to trigger overt ergative case (agreement with both v and T). This distinction between abstract and morphological case factors into the analysis of the switch-reference system of Amahuaca, which I argue is sensitive to abstract case. In addition to case-sensitivity, Amahuaca’s switch-reference system shows the typologically unusual property of tracking the reference of all arguments of the verb, not only subjects. I propose that this system arises through adjunct complementizer agreement that probes both the adjunct and matrix arguments directly through cyclic expansion of the probe. Through these two investigations, I conclude that Amahuaca provides support for a narrowly cyclic model of Agree in which each instance of Merge defines a new cycle of Agree (Rezac 2003, 2004; Béjar and Rezac 2009). Further, the empirical facts can be most straightforwardly accounted for if we assume that some probes are insatiable, agreeing with all possible goals in their search space (Deal 2015b). Finally, despite the fact that some agreement in Amahuaca appears to be long distance, I argue that the data can be captured under the fairly conservative assumption that Agree is always under c-command and is always phase-bound

Guiding Ethical Principles in Engineering Biology Research

Engineering biology is being applied toward solving or mitigating some of the greatest challenges facing society. As with many other rapidly advancing technologies, the development of these powerful tools must be considered in the context of ethical uses for personal, societal, and/or environmental advancement. Researchers have a responsibility to consider the diverse outcomes that may result from the knowledge and innovation they contribute to the field. Together, we developed a Statement of Ethics in Engineering Biology Research to guide researchers as they incorporate the consideration of long-term ethical implications of their work into every phase of the research lifecycle. Herein, we present and contextualize this Statement of Ethics and its six guiding principles. Our goal is to facilitate ongoing reflection and collaboration among technical researchers, social scientists, policy makers, and other stakeholders to support best outcomes in engineering biology innovation and development

Keck Planet Imager and Characterizer: demonstrating advanced exoplanet characterization techniques for future extremely large telescopes (Conference Presentation)

The Keck Planet Imager and Characterizer (KPIC) is an upgrade to the Keck II adaptive optics system enabling high contrast imaging and high-resolution spectroscopic characterization of giant exoplanets in the mid-infrared (2-5 microns). The KPIC instrument will be developed in phases. Phase I entails the installation of an infrared pyramid wavefront sensor (PyWFS) based on a fast, low-noise SAPHIRA IR-APD array. The ultra-sensitive infrared PyWFS will enable high contrast studies of infant exoplanets around cool, red, and/or obscured targets in star forming regions. In addition, the light downstream of the PyWFS will be coupled into an array of single-mode fibers with the aid of an active fiber injection unit (FIU). In turn, these fibers route light to Keck's high-resolution infrared spectrograph NIRSPEC, so that high dispersion coronagraphy (HDC) can be implemented for the first time. HDC optimally pairs high contrast imaging and high-resolution spectroscopy allowing detailed characterization of exoplanet atmospheres, including molecular composition, spin measurements, and Doppler imaging. We will provide an overview of the instrument, its science scope, and report on recent results from on-sky commissioning of Phase I. We will discuss plans for optimizing the instrument to seed designs for similar modes on extremely large telescopes

Theory and description in African Linguistics: Selected papers from the 47th Annual Conference on African Linguistics

The papers in this volume were presented at the 47th Annual Conference on African Linguistics at UC Berkeley in 2016. The papers offer new descriptions of African languages and propose novel theoretical analyses of them. The contributions span topics in phonetics, phonology, syntax, semantics, and pragmatics and reflect the typological and genetic diversity of languages in Africa. Four papers in the volume examine Areal Features and Linguistic Reconstruction in Africa, and were presented at a special workshop on this topic held alongside the general session of ACAL
