We study the wage structure during economic transition in the context of Chinese cities and examine the effect of China’s urban housing reforms on the urban wage structure (1988-2005). We find that these reforms, which untied access to housing from state-sector employment, shifted approximately 17% of the labor force from the state sector to the private sector, increasing the private sector lab...

development of a numerical model which describes launching of offshore jackets from barge is presented in this paper. in this model, in addition to capabilities of commercial softwares, water entry forces on jacket members and an implicit newmark solution technique are included. the results are in general agreement with other numerical software’s available (sacs). fluid forces acting on jacket ...

in order to design and manufacturing some postharvest equipment, determination of some hydrodynamic properties of crops are necessary. the quality of products in global and local markets can be increased by applying these properties and receive economical benefits. for these purpose, two local varieties of apples in the east azerbaijan province, iran(asheghi and gare yapraq)were selected.ashegh...

measurement of the loads exerted on the limb is a fundamental part of designing of an assistive device, which has been done by using strain gauges or a transducer. although calculation of loads applied on an orthosis coefficients achieved from calibration is a standard way, most of researchers determined the loads based on available equations. therefore, the aim of this research is finding the ...

For many applications, antibodies need to be engineered toward maximum affinity. Strategies are in demand to especially optimize this process toward slower dissociation rates, which correlate with the (un)binding forces. Using single-molecule force spectroscopy, we have characterized three variants of a recombinant antibody single-chain Fv fragment. These variants were taken from different step...

Reversible self-assembly of nanoparticles into ordered structures is essential for both fundamental study and practical applications. Although extensive work has been conducted, the demand for simple, cheap, reversible, and versatile ordering methods is still a central issue in current nanoscience and nanotechnology. Here we report a reversible and precise self-assembly of nanoparticles through...

Ears are an emergent biometric accruing application advantages including no requirement for subject contact and acquisition without demand. To recognize a subject's ear, we aim to extract a characteristic vector from a human ear image that may subsequently be used to identify or confirm the identity of the owner. Towards this end, a novel force field transformation and potential well extraction...

Using the currency demand and DYMIMIC approaches estimates about the size of the shadow economy in 18 Asian and 21 OECD countries are presented. The average size of the shadow economy (in percent of official GDP) over 1998/99 in 18 Asian countries is 25.8% and i n 21 OECD countries 16.7% of " official " GDP. The average size of the shadow economy labor force (in percent of the official labor fo...

We investigated the ability of older adults to intentionally adapt their sensorimotor output to differing time and frequency properties (1/f noise structure) of a target-force target waveform. We tested the hypothesis that elderly adults are less adaptable than their younger counterparts to the time- and frequency-dependent demands of continuous sensorimotor output and that this effect is media...

Absenteeism is affected by the sickness benefit system. Countries with generous compensation during sick leaves also experience high numbers of sick leave. Sick leaves may vary over the business cycle due to unemployment disciplining effects or changes in labour force composition. The latter hypothesis maintains that sickness may be pro-cyclical due to employment of “marginal” workers with poor...
