In this paper, I argue for a new, theory-neutral approach to polarity effects resting upon the idea that the choice of marker for a given feature specification is determined by the choice of marker for a minimally different specification. In paradigms instantiating polarity effects, the matching of morpho-syntactic and phonological features proceeds by natural class based-rules, but is partly o...

This study explores morpho-syntactic reading comprehension in 19 Spanish children who received a cochlear implant (CI) before 24 months of age (early CI [e-CI]) and 19 Spanish children who received a CI after 24 months (late CI [l-CI]). They all were in primary school and were compared to a hearing control (HC) group of 19 children. Tests of perceptual reasoning, working memory, receptive vocab...

Abstract. The quantification of active tectonics from geomorphological and morphometric approaches commonly implies that erosion have reached a certain balance. Such equilibrium conditions are however rare in nature, as questioned documented by recent theoretical studies indicating drainage basins may be perpetually re-arranging even though tectonic climatic remain constant. Here, we document t...

Coastal and ocean island volcanoes are renowned for having unstable flanks. This can lead to flank deformation on a variety of temporal spatial scales ranging from slow creep catastrophic sector collapse. A large section these flanks is often below sea level, where information the volcano-tectonic structure ground limited. Consequently, kinematic models that attempt explain measured onshore ass...

Morphotectonic investigations were carried out by the use of morphometric indices which serve as a tool of identification in regions with active tectonic warp. Landforms in active deformation area are produced from relations of tectonic and surficial processes. One of the most significant landforms underground is rivers that are extremely responsive to tectonic movements mainly uplift and tilti...

Induced earthquakes currently pose a significant hazard in the central United States, but there is considerable uncertainty about the severity of their ground motions. We measure stress drops of 39 moderate-magnitude induced and tectonic earthquakes in the central United States and eastern North America. Induced earthquakes, more than half of which are shallower than 5 km, show a comparable med...

This study aimed to describe the morphoanatomical characters of fruits, seeds and seedlings, in addition characterizing anatomy leaves trunk species Protium altsonii Sandwith. The wood were collected Sustainable Development Reserve Iratapuru River (SDR), Amapá. Cross longitudinal sections cut with a rotary microtome. As for characteristics, it was observed that fruits are globose ovoid, slightl...

Introduction Changes in land surface shape in active tectonic  zones result from interplay between tectonic forces and surface processes (Keller and Pinter, 1996; Keller et al., 1999). Salt Domes  are dome-shaped Geological structures whose central core is composed of salt. Their economic importance is due to the location of oil tanks in structures with salt domes and also the presence of sulf...

[1] A simple dynamic model based on boundary layer theory shows that dynamic topography is unlikely to vary significantly in response to short term ( 20 Myr) variations in the mean tectonic velocity. Tectonic velocities essentially mirror variations in mantle viscosity, but are not indicative of substantial modification of dynamic topography, which primarily reflects mass anomalies in the mantl...
