Neural correlates of semantic and syntactic processes in the comprehension of case marked pronouns: Evidence from German and Dutch

Background  

It is well known that both semantic and syntactic information play a role in pronoun resolution in sentences. However, it is unclear what the relative contribution of these sources of information is for the establishment of a coreferential relationship between the pronoun and the antecedent in combination with a local structural case constraint on the pronoun (i.e. case assignment of a pronoun under preposition governing). In a prepositional phrase in German and Dutch, it is the preposition that assigns case to the pronoun. Furthermore, in these languages different overtly case-marked pronouns are used to refer to male and female persons. Thus, one can manipulate biological/syntactic gender features separately from case marking features.     

An in vitro characterisation comparing carbon paste and Pt microelectrodes for real-time detection of brain tissue oxygen

In vitro characterisation results for O(2) reduction at Pt-based microelectrodes are presented and compared with those for carbon-paste electrodes (CPEs). Cyclic voltammetry indicates a potential of -650 mV vs. SCE is required for cathodic reduction at both electrode types, and calibration experiments at this potential revealed a significantly higher sensitivity for Pt (-0.091 ± 0.006 μAmm(-2)μM(-1) vs. -0.048 ± 0.002 μAmm(-2)μM(-1) for CPEs). Since Pt electrodes are readily poisoned through contact with biological samples selected surface coated polymers (polyphenylenediamine (PPD), polymethyl methacrylate (PMMA) and Rhoplex(?)) were examined in biocompatibility studies performed in protein, lipid and brain tissue solutions. While small and comparable decreases in sensitivity were observed for bare Pt, Pt-Rhoplex and PMMA there was minimal change at the Pt-PPD modified electrode for each 24h treatment, including an extended 3 day exposure to brain tissue. The polymers themselves had no effect on the O(2) response characteristics. Further characterisation studies at the Pt-based microelectrodes confirmed interference free signals, no effect of pH and ion changes, and a comparable detection limit (0.08 ± 0.01 μM) and response time (<1 s) to CPEs. Although a significant temperature effect (ca. 3% change in signal for each 1 °C) was observed it is predicted that this will not be important for in vivo brain tissue O(2) measurements due to brain temperature homeostasis. These results suggest that amperometric Pt electrodes have the potential to be used reliably as an alternative to CPEs to monitor brain tissue O(2) over extended periods in freely-moving animals.     

Power indices for multicandidate voting games

In Bolger (1983), a “Banzhaf-type” power index was used to measure the voting power of individual voters in an electoral college presidential election. It was pointed out that this power index could be affected by the addition of a “dummy” player. In this paper we introduce a modification which is dummy-independent. We also derive an efficient, linear index which has different properties than the index introduced by Myerson (1977).
