Laboratory experiments on the linguistic consequences of communicative interaction

 

If enough people take the same shortcut across a lawn, their footsteps will eventually create a path marking the route. While such a path certainly results from human action, it is not deliberately designed in the way that paved roads and highways are. Could this be a useful analogy for understanding the design of language? I will present experimental evidence indicating that — if we take a cultural-evolutionary approach to language — the answer is likely to be yes. In particular I will present a set of experiments investigating the emergence, through repeated communicative interaction, of two different kinds of structure: combinatoriality (the recombination of a small set of basic forms, such as letters or phonemes, into more complex forms) and dialectal variation (the use of particular linguistic variants by members of particular social groups). In both cases structure emerges that resembles the structure of existing languages and does so in an environment in which variables can be directly manipulated that are hard to isolate outside the laboratory. Finally, I briefly illustrate how such methods can be applied to non-linguistic tasks, shedding light on how structure may arise in similar ways in different kinds of cultural behavior.

Molecular and Nanoscale Approaches to Solar Energy Transduction

 

Abstract

Solar energy offers a desirable approach to fulfilling global human energy demands with minimal environmental impact provided efficient, low-cost systems can be developed for its capture, conversion and storage.1-2 In biology, enzymes catalyze a myriad of technologically relevant chemical reactions by providing discrete three-dimensional environments for binding substrate, releasing product, and lowering transition-state energies along a reaction coordinate. Thus, in accordance with the Sabatier principle, they can have exceptionally high activities and, perhaps more importantly, selectivity for specific chemical transformations.

 

A method for facile connection of biomimetic fuel production catalysts to semiconductor photocathodes will be presented.3-4 Successful attachment is characterized by grazing angle attenuated total reflection Fourier transform infrared spectroscopy (GATR-FTIR) as well as X-ray photoelectron spectroscopy (XPS) and X-ray absorption near edge structure spectroscopy (XANES). Photoelectrochemical experiments analyzing the energetics and efficiency of these constructs will also be discussed.5 These results give insights to designing improved photocathodes with additional performance gains and illustrate the potential to directly couple human-engineered catalysts for fuel production with light capture and conversion materials. This approach could allow catalysts made from earth-abundant elements to replace the use of precious metals currently implemented in many solar-fuel generator prototypes as well as other technologies capable of reducing net carbon dioxide emissions.
