چکیده

The Argument from the Poverty of the Stimulus (APS) still dominates a substantial part of the research in theoretical linguistics. While in generative approaches, the APS provides the foundation of the innateness hypothesis; in other paradigms (usage-based, interactionist, cognitivist) the argument is central because it is argued against it. Poverty of the stimulus arguments are indeed theoretical because they do little to empirically back their premises. Following Pullum & Scholz (2002) the logic of the argument has two premises. First, language is either genetically encoded or learned data-driven. The second premise, however, is meant to be empirical, that is, infants learn what is not given in the input. Since, by definition, data driven means that everything can be learned from the input, the empirical premise excludes data driven strategies as an option. Now, only one alternative remains in the initial premise. Thus one can deduce modus tollens the genetically encoded strategy as the correct alternative via exclusion. Although the conclusion is correct, the result can be questioned because the premises are far from plausible nowadays. Accepting that the two alternatives postulated in the first premise are somewhat sufficient, the empirical premise seems more problematic. Also known as lack of evidence, this premise is a simple assertion without a systematic and comprehensive proof. The assumption was certainly still acceptable at the time of its conception. Today, however, we have collected specific and representative corpora, developed a body of sophisticated methodologies for quantitative analyses, and used the computational power to carry out complex

Gains from diversification on convex combinations: A majorization and stochastic dominance approach

By incorporating both majorization theory and stochastic dominance theory, this paper presents a general theory and a unifying framework for determining the diversification preferences of risk-averse investors and conditions under which they would unanimously judge a particular asset to be superior. In particular, we develop a theory for comparing the preferences of different convex combination...

Improved immunogenicity of tetanus toxoid by Brucella abortus S19 LPS adjuvant.

BACKGROUND Adjuvants are used to increase the immunogenicity of new generation vaccines, especially those based on recombinant proteins. Despite immunostimulatory properties, the use of bacterial lipopolysaccharide (LPS) as an adjuvant has been hampered due to its toxicity and pyrogenicity. Brucella abortus LPS is less toxic and has no pyrogenic properties compared to LPS from other gram negati...

Steady electrodiffusion in hydrogel-colloid composites: macroscale properties from microscale electrokinetics.

A rigorous microscale electrokinetic model for hydrogel-colloid composites is adopted to compute macroscale profiles of electrolyte concentration, electrostatic potential, and hydrostatic pressure across membranes that separate electrolytes with different concentrations. The membranes are uncharged polymeric hydrogels in which charged spherical colloidal particles are immobilized and randomly d...

Perturbative Analysis of Dynamical Localisation

In this paper we extend previous results on convergent perturbative solutions of the Schrödinger equation of a class of periodically timedependent two-level systems. The situation treated here is particularly suited for the investigation of two-level systems exhibiting the phenomenon of (approximate) dynamical localisation. We also present a convergent perturbative expansion for the secular fre...

Collinear contextual suppression

The context of a target can modulate behavioral as well as neural responses to that target. For example, target processing can be suppressed by iso-oriented surrounds whereas it can be facilitated by collinear contextual elements. Here, we present experiments in which collinear elements exert strong suppression whereas iso-oriented contextual surrounds yield no contextual modulation--contrary t...
