In directional statistics, the von Mises distribution is a key element in analysis of circular data. While there general agreement regarding estimation its location parameter μ, several methods have been proposed to estimate concentration κ. We here provide thorough evaluation behavior 12 such estimators for datasets size N ranging from 2 8192 generated with κ 0 100. detailed results as well gl...

Consider the class of C-smooth SL(2,R) valued cocycles, based on the rotation flow on the two torus with irrational rotation number α. We show that in this class, (i) cocycles with positive Lyapunov exponents are dense and (ii) cocycles that are either uniformly hyperbolic or proximal are generic, if α satisfies the following Liouville type condition: ∣ α− pn qn ∣ ∣ ≤ Cexp(−q n ), where C > 0 a...

central to vygotsky-inspired sociocultural theory (sct) is the notion of zpd seen by sla researchers as a useful framework within which l2 teaching and learning can take place. van lier (2004) argues that the zpd could be activated in diverse proximal contexts (pcs) and is not limited to the expert-novice scenario. . this study probed whether iranian efl learners' collaborative task performance...

This paper investigates the role recursive structures play in prosody. In current understanding, phonological phrasing is computed by a general syntax–prosody mapping algorithm. Here, we are interested structure that arises response to morphosyntactic needs be mapped. We investigate types of found prosody, specifically: For prosodic category κ, besides adjunctive type recursion κ[κ x], κ[x κ], ...

We prove the following: (1) If κ is weakly inaccessible then NSκ is not κ+-saturated. (2) If κ is weakly inaccessible and θ < κ is regular then NSθ κ is not κ +saturated. (3) If κ is singular then NS κ+ is not κ++-saturated. Combining this with previous results of Shelah, one obtains the following: (A) If κ > א1 then NSκ is not κ+-saturated. (B) If θ+ < κ then NSθ κ is not κ +-saturated.
