The paper discusses the so-called adverbial use of the wh-pronoun was ('what'), which establishes a non-standard interrogative construction type in German. It argues that the adverbial use of was ('what') is based on the lexical properties of a categorically deficient pronoun was ('what'), which bears a causal meaning. In addition, adverbial was ('what') differs from canonical argument was ('what') as it is analyzed as a functor which is generated in clause-initial position.
By means of empirical facts mainly provided by d'Avis (2001) it is shown that was ('what') behaves ambivalently regarding the wh-property: On the one hand, was ('what') can introduce an interrogative clause, but on the other hand it cannot license wh-phrases in situ. While formally analyzing the data against the background of existing accounts on wh-interrogatives couched in the framework of Head-driven Phrase Structure Grammar, an analysis is developed that separates two pieces of information to keep track of the wh-information percolating in an interrogative clause. Whereas the WH-value models wh-fronting and pied-piping phenomena, the QUE value links syntactic and semantic information and thus keeps track of wh-phrases in-situ.
The chiral critical surface is a surface of second order phase transitions bounding the region of
first order chiral phase transitions for small quark masses in the fmu;d;ms;mg parameter space.
The potential critical endpoint of the QCD (T;m)-phase diagram is widely expected to be part of
this surface. Since for m = 0 with physical quark masses QCD is known to exhibit an analytic
crossover, this expectation requires the region of chiral transitions to expand with m for a chiral
critical endpoint to exist. Instead, on coarse Nt = 4 lattices, we find the area of chiral transitions
to shrink with m, which excludes a chiral critical point for QCD at moderate chemical potentials
mB < 500 MeV. First results on finer Nt = 6 lattices indicate a curvature of the critical surface
consistent with zero and unchanged conclusions. We also comment on the interplay of phase
diagrams between the Nf = 2 and Nf = 2+1 theories and its consequences for physical QCD.
The present paper gives an account of Serial Verb Constructions (SVCs) in Mandarin Chinese. After a typological presentation of the phenomenon, we give an overview of the Chinese data with examples of the semantic variations of SVCs. The inventory of SVC types is classified according to causal and temporal relations between the components. We also discuss the pragmatic conditions on the use of SVCs as well as alternative, semantically equivalent constructions. A HPSG-analysis is proposed for marked SVCs, which uses the interaction between aspect marking and the set of possible subordinative relations to deduce the extra-lexical meaning of the construction. Particular attention is payed to the syntactically peculiar SVC with shared internal arguments, which is accounted for by a non-cancellation approach to valence requirements.
Perturbation theory for non-abelian gauge theories at finite temperature is plagued by infrared
divergences which are caused by magnetic soft modes ~ g2T, corresponding to gluon fields of
a 3d Yang-Mills theory. While the divergences can be regulated by a dynamically generated
magnetic mass on that scale, the gauge coupling drops out of the effective expansion parameter
requiring summation of all loop orders for the calculation of observables. Some gauge invariant
possibilities to implement such infrared-safe resummations are reviewed. We use a scheme based
on the non-linear sigma model to estimate some of the contributions ~ g6 of the soft magnetic
modes to the QCD pressure through two loops. The NLO contribution amounts to ~ 10% of the
LO, suggestive of a reasonable convergence of the series.
Word formation in Distributed Morphology (see Arad 2005, Marantz 2001, Embick 2008): 1. Language has atomic, non-decomposable, elements = roots. 2. Roots combine with the functional vocabulary and build larger elements. 3. Roots are category neutral. They are then categorized by combining with category defining functional heads.
The nervous system probably cannot display macroscopic quantum (i.e. classically impossible) behaviours such as quantum entanglement, superposition or tunnelling (Koch and Hepp, Nature 440:611, 2006). However, in contrast to this quantum "mysticism" there is an alternative way in which quantum events might influence the brain activity. The nervous system is a nonlinear system with many feedback loops at every level of its structural hierarchy. A conventional wisdom is that in macroscopic objects the quantum fluctuations are self-averaging and thus not important. Nevertheless this intuition might be misleading in the case of nonlinear complex systems. Because of a high sensitivity to initial conditions, in chaotic systems the microscopic fluctuations may be amplified upward and thereby affect the system’s output. In this way stochastic quantum dynamics might sometimes alter the outcome of neuronal computations, not by generating classically impossible solutions, but by influencing the selection of many possible solutions (Satinover, Quantum Brain, Wiley & Sons, 2001). I am going to discuss recent theoretical proposals and experimental findings in quantum mechanics, complexity theory and computational neuroscience suggesting that biological evolution is able to take advantage of quantum-computational speed-up. I predict that the future research on quantum complex systems will provide us with novel interesting insights that might be relevant also for neurobiology and neurophilosophy.
The Project European Privacy Open Space (PrivacyOS) aims at bringing together industry, SMEs, Government, Academia and Civil Society to foster development and deployment of privacy infrastructures for Europe. The general objectives of PrivacyOS are to create a longterm collaboration in the thematic network and establish collective interfaces with other EU projects. Participants exchange research and best practices, as well as develop strategies and joint projects following four core policy goals: Awareness-rising, enabling privacy on the Web, fostering privacy-friendly Identity Management, and stipulating research.

This report focuses on the 3rd PrivacyOS conference, which was held in Vienna, October 26th and 27th 2009, co-located with the Austrian Big Brother Awards. 50 participants attended the conference and devised the agenda with 21 presentations in two parallel tracks. The topics of the presentations discussed included, amongst others: data protection awareness, data protection in healthcare, data protection in the Web 2.0, privacy-related technologies such as EnCoRe, TOR or Microformats as well as regulatory, cultural and sociological implications of data protection. Also at the 3rd PrivacyOS conference the software product “KiwiSecurity” was awarded the EuroPriSe Seal (European Privacy Seal, www.european-privacy-seal.eu). EuroPriSe is an initiative of the data protection authority Unabhängiges Landeszentrum für Datenschutz Schleswig-Holstein (ULD), Germany. It has been started as a European Project under the eTEN programme.
