Combining Prototypes: A Selective Modification Model
We propose a model that accounts for how people construct prototypes for composite concepts out of prototypes for simple concepts. The first component of the model is a prototype representation for simple, noun concepts, such as fruit, which specifies: (1) the relevant attributes of the concepts, (2) the possiblevalues of each attribute, (3) the salience of each value, and (4) the diognosticity...
متن کاملCombining time DEA scores using a dynamic panel data model
We define a combined DEA score to evaluate efficiency in agricultural research. The production model we propose considers efficiency measurements under variable returns to scale for each year in the period 2012–2017. We postulate a first-order autoregressive process in the presence of covariates, to explain efficiency. Powers of the autocorrelation coefficient estimated assuming a dynamic panel...
متن کاملModification in non-combining idioms
This squib discusses metalinguistic modification, expressives, domain modification, hypallage, and conjunctive modification within verb phrase idioms. The examples presented here show that non-combining idioms, to use terminology based on that of Nunberg, Sag & Wasow 1994, allow for modifiers on their internal constituents, but only in certain circumstances. This observation is shown to be deri...
متن کاملSelective chemical protein modification.
Chemical modification of proteins is an important tool for probing natural systems, creating therapeutic conjugates and generating novel protein constructs. Site-selective reactions require exquisite control over both chemo- and regioselectivity, under ambient, aqueous conditions. There are now various methods for achieving selective modification of both natural and unnatural amino acids--each ...
متن کاملCombining Sense and Nonsense Codon Reassignment for Site-Selective Protein Modification with Unnatural Amino Acids.
Incorporation of unnatural amino acids (uAAs) via codon reassignment is a powerful approach for introducing novel chemical and biological properties to synthesized polypeptides. However, the site-selective incorporation of multiple uAAs into polypeptides is hampered by the limited number of reassignable nonsense codons. This challenge is addressed in the current work by developing Escherichia c...
