Car Manufacturing Compared : Korea, Phillippines, UK
Winfield, Ian,Jackson, P.R.,Kang, Duk Su 한국생산성학회 2000 THE JOURNAL OF PRODUCTIVITY Vol.6 No.1
This paper compares employee effectiveness in car manufacturing under different but nonetheless related manufacturing conditions in three countries. In each of the countries there has been a move to employ HRM policies designed to engage employee commitment and support. These policies emanate, among other places, from Japan and have been largely taken up by car manufacturers throughout S.E. Asia, Korea and the developed industrial world. A survey of how workers react to these initiatives has been conducted in three sites in these three countries. Measures of commitment; of level of control over work; of production pressure; job complexity and responsibility have been made and comparisons drawn. The research shows that there are wide variations in reactions to these policies with indications that Korean manufacturers may have learned important lessons from experiences elsewhere. This may be particularly relevant since overcapacity in car manufacturing plants throughout the world force manufacturers to look for lower break-even points: a new round of work intensification looks set to sweep the manufacturing world.
Self‐Assembled, Molecularly Aligned Conjugated Polymer Nanowires via Dewetting
Chang, Shion Seng,Tsoi, Wing C.,Higgins, Anthony M.,Kim, Ji‐,Seon,Winfield, Jessica M.,James, David T. WILEY‐VCH Verlag 2010 Advanced Functional Materials Vol.20 No.18
<P><B>Abstract</B></P><P>High aspect‐ratio poly(9,9′‐dioctylfluorene) (F8) nanowires are fabricated on top of silicon/amorphous Teflon substrates, by dewetting of F8 thin‐films. The conjugated nature of the polymers enables the self‐assembly of continuous molecularly‐aligned nanowires of several micrometers in length and tens of nanometers width, without using a template. The sizescale of the dewetted morphology can be controlled by varying the thickness of the F8 and amorphous Teflon layers. As predicted by van der Waals theory the characteristic sizescale of the dewetted morphology increases with F8 film thickness. However, the dependence of the characteristic sizescale on amorphous Teflon thickness is not accounted for, even qualitatively, by standard spinodal theory with van der Waals forces as the de‐stabilizing force across the F8 film. The Rayleigh instability is strongly suppressed in the F8 nanowires in the late stages of dewetting, compared to isotropic, amorphous polymers. Polarized Raman measurements show a systematic increase in molecular alignment along the axis of the nanowires as their width is reduced below the typical liquid‐crystalline domain size in polyfluorene films. Thus the dewetting process aligns the polymers, and the aligned polymers suppress the Rayleigh instability and enable the formation of high aspect‐ratio continuous nanowires.</P>
