In this paper we analyse the relative importance of individual ability and labour market institutions, including public sector wage setting and trade unions, in determining earnings differences across different types of employment. To do this we use the KwaZulu-Natal Income Dynamics Study data from South Africa, which show extremely large average earnings differentials across different types of...

Traditional tools of welfare economics identify the envy-related welfare loss from conspicuous consumption only under very strong assumptions. Measured income and life satisfaction offers an alternative for estimating such consumption externalities. The approach is developed in the context of luxury car consumption (Ferraris and Porsches) in Switzerland. Results from household panel data and fi...

This study examines experimentally, in situ, the influence of four scales of heterogeneity (0, 1, 10, 100 mm) and the hierarchical combination of those scales of heterogeneity (0 + 1 + 10, 0 + 1 + 100, 0 + 10 + 100, 0 + 1 + 10 + 100 mm) on the early establishment of a sessile marine littoral epibenthic community. The study was carried out in St. Andrews, New Brunswick (Canada) from July to Octo...

Current density [mA/cm] L um in an ce [c d/ m 2 ] Voltage [V] Over last several years, light-emitting devices based on organic materials have been attractive research subjects because of their potential applicability to large size flat panel displays and solid-state lighting with low fabrication costs and easy manufacturing processes. Recently, the topic of white light generation from singlelay...

The broad goals of this project are to develop new techniques of human interaction with stereo displays, particularly autostereoscopic (AS) displays. Autostereoscopic displays produce a 3D visual sensation to one or more observers without the use of glasses, goggles, helmets, or headtracking. We are developing new techniques for interactive input and manipulation of threedimensional data using ...

Zenithal Bistable Devices (ZBD) exhibit rugged image storage, excellent optical performance, fast latching and infinite multiplexibility. These properties arise from the use of the grating layer used to align a nematic liquid crystal. Such gratings also offer a high degree of design flexibility. In the present work, grating shape is varied within each pixel to introduce error-free analogue gre...

The relation between typical flat panel display characteristics and display quality was studied. Subjective preferences were obtained with respect to simulated black-on-white flat panel displays. The displays differed in the sort of separation between the display elements and the shape of these elements. Further, the height/width ratio of the front was studied in relation with a fixed font matr...
