The distribution of copular verbs in Spanish is one of the most researched topics in Spanish linguistics: from traditional grammarians to contemporary linguists, many have attempted to capture a very complex and puzzling distribution. As is well-known, Spanish has two main copular verbs, ser and estar, that overlap in a number of contexts. As a first approximation ser combines with predicates t...

The application of an airborne electronically steered thinned array L-band radiometer (ESTAR) for soil moisture mapping was investigated over the semiarid rangeland Walnut Gulch Watershed located In southeastern Arizona. During the experiment, antecedent rainfall and evaporation were very dif ferent and resulted in a wide range of soil moisture conditions. The high spatial variability of rainfa...

The smooth threshold autoregressive (STAR) model is by far the most successful model in explaining the well-known two PPP puzzles. The nonlinearity in STAR captures the nature of vast transaction costs in trade, sunk costs in (foreign) investment, and hetergeneity in agents. In this paper, we use a variant of STAR, the Exponential STAR (ESTAR), to study the exchange rate dynamics in China durin...

Esta estrategia debe estar enfocada en explotar las fortalezas y manejar las debilidades de la organización, para posteriormente permitir la operatibilización de la estrategia mediante la correcta combinación de indicado...

We present the results of two experiments (an Elicitation Task and a Picture Matching Task) that test 4–5 year-old children’s ability to distinguish between the Spanish copulas ser and estar, when copula choice depended on the properties of the context. Departing from an analysis that relies on two different types of stative predicates (stativity associated with lack of aspectual information an...
