Are there different kinds of appositive relative clauses?

In his latest book on relative clauses, Cinque claims that there are two fundamentally different kinds of appositive (non-restrictive) relative clauses. The unintegrated ones are the typical English type, the integrated ones are found in various languages, including Chinese and Japanese. This second type shares some characteristics with restrictive relatives, and seems to require a different syntactic analysis. Some languages, like Italian, supposedly have both types. A list of a dozen criteria differentiates the two, such as the use of relative pronouns and the possibility of heavy pied piping. However, when we carefully look at Dutch and other languages, the picture starts to blur considerably, and an abundance of (micro)variation shows up. This is problematic. I argue that the suggested criteria do not add up to two natural classes at all and are in fact non-explanatory. Therefore, we need to focus on what is truly fundamental to non-restrictiveness, which leads to a different perspective on the matter.</p

On equivalence classes in iterative learning control

This paper advocates a new approach to study the relation between causal iterative learning control (ILC) and conventional feedback control. Central to this approach is the introduction of the set of admissible pairs (of operators) defined with respect to a family of iterations. Considered are two problem settings: standard ILC, which does not include a current cycle feedback (CCF) term and CCF-ILC, which does. By defining an equivalence relation on the set of admissible pairs, it is shown that in the standard ILC problem there exists a bijective map between the induced equivalence classes and the set of all stabilizing controllers. This yields the well-known Youla parameterization as a corollary. These results do not extend in full generality to the case of CCF-ILC; though gain every admissible pair defines a stabilizing equivalent controller, the converse is no longer true in general

Observations of quasar host galaxies with laser guide star AO

We report on observations of two quasar host galaxies made with the Lick Observatory adaptive optic system using a laser guide star tuned to the wavelength of the sodium D lines. A brief outline of the system is given, and a description of its performance when obtaining science data. We discuss techniques for obtaining calibration of the point spread function and the analysis steps required to obtain useful scientific results. We present H-band images of quasar host galaxies made with the system. Estimates of the host galaxy magnitudes and central black hole masses were made from these data. These are the first observations of quasar host galaxies with a sodium laser guide star

Interpreting idioms in a second language:The role of context and transfer in interpreting English idioms by native Dutch speakers

How do people understand figurative speech in a foreign language? What strategies do they use? By means of an online questionnaire, this study investigated to what extent contextual information and transfer play a role in the interpretation of idioms in a second language, controlling for familiarity. Sixty-one native speakers of Dutch were asked to guess the correct interpretation of English idioms with and without a Dutch equivalent, presented with and without context, out of four answer options. The results showed that correctly interpreting an idiom depends on both the presence of context and the possibility of transfer. More correct interpretations were given when an idiom was presented in a context, but only for English idioms without an equivalent in the native language. English idioms with an equivalent in Dutch, often rated as familiar, were mostly understood correctly. We interpret this result as the involvement of transfer from the native language
