Miocene surface uplift and orogenic evolution of the southern Andean Plateau (central Puna), northwestern Argentina.

We present stable hydrogen-isotope analyses of volcanic glass ([Formula: see text]Dg) and radiometric ages (U-Pb zircon, U-Th calcite, AMSC) from deformed sedimentary deposits in the vicinity of the intermontane Pocitos Basin in the central Puna of the Andean Plateau at about 24.5°S. Our results demonstrate 2-km surface uplift since the middle to late Miocene and protracted shortening that persists until the present day, while other sectors of the Puna show evidence for tectonically neutral and/or extensional settings.

Accelerated Miocene incision along the Yangtze River driven by headward drainage basin expansion.

Along the southeastern margin of the Tibetan Plateau, the onset of rapid fluvial incision during the Miocene is commonly attributed to growth of high topography. Recent recognition of lacustrine strata preserved atop interfluves, however, suggest that headward expansion of river networks drove migration of the topographic divide. Here, we explore the impact of this process on fluvial incision along the Yangtze River.

Quality assessment, inclusive community development, and collective learning: An institutional perspective from Germany.

This article reviews the German discourse on quality of life, quality assurance, and outcome measurement in services for persons with intellectual disabilities. Following institutional assumptions of path dependencies in organizational development, it is argued that concepts such as quality assurance must be understood in the context of the national support system development. For the Federal Republic of Germany, it can be noted that previous approaches to quality assurance of services based on measurement and evaluation tools have not been the drivers of innovation for inclusion.

Cenozoic evolution of the steppe-desert biome in Central Asia.

The origins and development of the arid and highly seasonal steppe-desert biome in Central Asia, the largest of its kind in the world, remain largely unconstrained by existing records. It is unclear how Cenozoic climatic, geological, and biological forces, acting at diverse spatial and temporal scales, shaped Central Asian ecosystems through time. Our synthesis shows that the Central Asian steppe-desert has existed since at least Eocene times but experienced no less than two regime shifts, one at the Eocene-Oligocene Transition and one in the mid-Miocene.
