Models are the core of scientific theory. Some researchers have argued that modeling is fundamental to scientific inquiry (e.g. Clement, 2000). There has been increased literature on how to use inquiry and modeling for science learning. However, challenges still exist. For example, how do different modeling tools and learning activities shape student learning trajectories? How do they impact st...

Mechanical venous thrombectomy (MVT) has gained popularity as an alternative to catheter-directed thrombolysis (CDL) and medical management (MM) of iliofemoral deep vein thrombosis (DVT), potentially combining the benefits a minimally invasive approach with lower risk bleeding shorter hospital stay. Emerging evidence shows MVT have excellent perioperative outcomes. However, cost effectiveness i...

English] Teams distributed across cultural, geographic and temporal boundaries, also known as multicultural virtual teams (MVTs), have been prevalent in international organizations. To provide guidance for MVT managers and support accumulation of prior experience, we establish a management model based on the extended adaptive structuration theory (EAST) and verify the model with 55 empirical st...

Abstract The ages of Zn-Pb deposits are exceptionally challenging to determine owing the lack suitable mineral chronometers and techniques. Here we present first result for in situ LA-ICP-MS U-Pb dating carbonates barite from a Mississippi Valley– type (MVT) deposit South China. Hydrothermal dolomite close textural paragenetic association with sulfides, calcite cement breccia ores, yield 473.4 ...

It is well established that social conditions often modify foraging behaviour, but the theoretical interpretation of the changes produced is not straightforward. Changes may be due to alterations of the foraging currency (the mathematical expression that behaviour maximizes) and/or of the available resources. An example of the latter is when both solitary and social foragers maximize rates of g...

Rational ligand design is a complex problem that can be divided into three parts: the search for optimal positions and orientations of functional groups in the binding site, the connection of such positions to form candidate ligands, and the estimation of their binding constants. Approaches for addressing the first two parts of the problem are described in the present work. They are applied to ...

OBJECTIVE To explore urban-rural differences in the mortality and hospital admission rates for unintentional injuries in the Republic of Ireland. DESIGN Standardised mortality ratios (SMRs) in residents of urban and non-city areas (called rural areas) from all causes of unintentional injury were calculated using Central Statistics Office mortality data from 1980-2000. Hospital admission data ...
