April 3, 2011 Abstract How does access to imported capital goods affect the quality of investment in poor countries? From 1949 to 1957, China imported most of its industrial plants from the Soviet Union, but in the late 1950s a series of political disputes ended their trading relationship. In 1960, China entered a period of autarky which persisted until 1978. In market settings, closure to capi...

this paper investigates the lateral vibration of single-layered graphene sheets based on a new theory called doublet mechanics with a length scale parameter. after a brief reviewing of doublet mechanics fundamentals, a sixth order partial differential equation that governs the lateral vibration of single-layered graphene sheets is derived. using doublet mechanics, the relation between natural f...

Helicity was calculated in Hurricane Bonnie (1998) using tropospheric-deep dropsonde soundings from the NASA Convection and Moisture Experiment. Large helicity existed downshear of the storm center with respect to the ambient vertical wind shear. It was associated with veering, semicircular hodographs created by strong, vortex-scale, radial-vertical flow induced by the shear. The most extreme v...

The frequency-dependent resistance and inductance can be calculated by solving an eddy current problem. In this paper, a model to describe such 3-D eddy current problem is proposed, which is called 3-D Omni-A model because both of the conducting and non-conducting regions are described in terms of magnetic vector potential A. Therefore, the induced voltages of the conductors may appear as the u...

Title of Document: RACE AND SELF IMAGE: HOW MOTHERS’ SOCIALIZATION MATTERS Heather Elizabeth Ridolfo, M.A., 2007 Directed By: Melissa Milkie, Ph.D. Department of Sociology For adolescents, having a strong Self is an important component of entering into adulthood successfully. Research suggests that despite living in a society often hostile to them, Black adolescents have Selves that is at least...

We contend that a range of phenomena characterizing temperate deposit-feeding communities in low-energy environments is strongly organized by two principal opposing forces: (1) spatially localized inputs of detritus or new recruits, leading to amosaic of initial patches, with subsequent impacts on spatio-temporal variation of species with limited mobility; and (2) the impact of mobile consumers...

This article reviews the progress in research on North Pacific mode waters of the past decade from the physical oceanographic perspective. The accumulation of satellite altimeter sea surface height data, the rapid growth of the Argo profiling float array, and the advancement in eddy-resolving ocean general circulation models have greatly improved the traditional views on the mode waters that we...

Sustainability is a global issue concerning future generations, but steps towards sustainable development must also be taken at the spatial scales of regions and at the temporal scales of individual lives. Different scales matter in social networks and in cultural realities, too. The fact that relatively small regions can dominate global markets for products based on continuous innovation point...

Traps were used to quantify charcoal production and transport during three experimental forest fires in Boreal Scandinavia. The traps were spatially arranged to collect charcoal particles inside burn areas, and outside burn areas at different distances (0.1–100 m) from the fire edge. The number of inside and outside traps was 280 and 424, respectively. Trap area was 48 cm. After the burn, trap ...

Use of the perceptually determined Bark frequency scale is investigated in an implementation of spectral difference onset detection. The study is carried out using a new external object for onset detection in Pure Data called bark∼, and contrasted with a similar object called bonk∼. While the filterbanks used in both of these objects feature more detailed resolution in low frequency bands, bark...
