We can differentiate between marked and unmarked focus strategies. The marked focus expressions are first syntactically characterized: the focused constituent is in sentence-initial position and is second always marked obligatorily by a focus marker, which is nɩ for non-subjects and N for subjects. Complementary to these structures, Foodo knows an elliptic form consisting of the focused constituent and a predication marker gɛ́. It will be shown that the two focus markers can be analyzed as having developed out of the homophone conjunction nɩ and that the constraints on the use of the focus markers can be best explained by this fact.}, language = {en} } @article{Schwarz2007, author = {Schwarz, Anne}, title = {The particles l{\´e} and l{\´a} in the grammar of Konkomba}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-19449}, year = {2007}, abstract = {The paper investigates focus marking devices in the scarcely documented North-Ghanaian Gur language Konkomba.

Yucatec Maya is a tone language, displaying a three-fold opposition in the tonal realization of syllables.

The calculus is proved sound and terminating. Further, it is shown that both the original DPLL calculus and the conflict-directed backtracking calculus with clause learning, as it is implemented in many current SAT solvers, are complete and proof-confluent instances of the LD calculus.}, language = {en} } @article{LipkeZitzmannAmbergeretal.2007, author = {Lipke, Katrin and Zitzmann, Max and Amberger, Manuel and Ehlert, Carsten and R{\"o}ßler, Dirk and Kr{\"u}ger, Frank and Ohrnberger, Matthias}, title = {Traveltime residuals at regional and teleseismic distances for SE-Asia}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-14117}, year = {2007}, abstract = {Traveltime residuals for worldwide seismic stations are calculated.

Their occurrence is correlated with and propably triggered by fluids that escape on the earth's surface near the epicentres. These fluids raise up periodically from a seemingbly deep-seated source in the upper mantle. Moment tensors for swarm events in 1997 indicate tensile faulting. However, they were determined under assumption of seismic isotropy although anisotropy can be observed. Anisotropy may obscure moment tensors and their interpretation. In 2000, more than 10,000 swarm earthquakes occurred near Novy Kostel, West Bohemia. Event triggering by fluid injection is likely. Activity lasted from 28/08 until 31/12/00 (9 phases) with maximum ML=3.2. High quality P-wave seismograms were used to retrieve the source mechanisms for 112 events between 28/08/00 and 30/10/00 using > 20 stations. We determine the source geometry using a new algorithm and different velocity models including anisotropy. From inversions of P waves we observe ML<3.2, strike-slip events on steep N-S oriented faults with additional normal or reverse components. Tensile components seem to be evident for more than 60\% of the processed swarm events in West Bohemia during the phases 1-7. Being most significant at great depths and at phases 1-4 during the swarm they are time and location dependent. Although tensile components are reduced when anisotropy is assumed they persist and seem to be important. They can be explained by pore-pressure changes due to the injection of fluids that raise up. Our findings agree with other observations e.g. correlation of fluid transport and seismicity, variations in b-value, forcing rate, and in pore pressure diffusion. Tests of our results show their significance.}, language = {en} } @article{RoesslerKruegerOhrnberger2007, author = {R{\"o}ßler, Dirk and Kr{\"u}ger, Frank and Ohrnberger, Matthias}, title = {Rupture propagation of the TsE (Mw7.7) on 17 July 2006 off-coast Java}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-12964}, year = {2007}, abstract = {The Mw=7.7 tsunamogenic earthquake (TsE) on 17 July 2006, 08:19:28 shock the Indian Ocean at about 15 km depth off-coast Java, Indonesia. It caused a local tsunami with wave heights exceeding 2 m. The death toll reached several hundred. Thousands of people were displaced. By means of standard array methods, we have investigated the propagation and the extent of the rupture front of the causative earthquake. Waveform similarity is expressed by means of the semblance. We back-propagate the semblance for first-arrival phases recorded at broad-band stations within teleseismic distances (30°-95°). Image enhancement is realised by stacking the semblance of 8 arrays within different epicentral and azimuthal directions. From teleseismic observations we find rupturing of a 200 x 100 km wide area in at least 2 phases with propagation from NW to SE and source duration >125 s. The event has some characteristics of a circular rupture followed by unilateral faulting with change in slip rate. Unusually slow rupturing (≈1.5 km/s) is indicated. Fault area and aftershock distribution coincide. Spatial and temporal resolution are frequency dependent. Studies of a Mw6.0 earthquake on 2006/09/21 and one synthetic source show a ≈1° limit in resolution. Retrieved source area, source duration as well as peak values for semblance and beam power increase with the size of the earthquake making possible an automatic detection and classification of large and small earthquakes.}, language = {en} } @article{JannedyMendozaDenton2005, author = {Jannedy, Stefanie and Mendoza-Denton, Norma}, title = {Structuring information through gesture and intonation}, series = {Interdisciplinary studies on information structure : ISIS ; working papers of the SFB 632}, journal = {Interdisciplinary studies on information structure : ISIS ; working papers of the SFB 632}, number = {3}, issn = {1866-4725}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-8774}, pages = {199 -- 244}, year = {2005}, abstract = {Face-to-face communication is multimodal.
