Group weariness and group negativism: Emerging attitudes in working life? Report on a project in progress.

Primary aim of project: to examine if Group Weariness (GW) exists, a concept defined as a n e g a t i v e a t t i t u d e t o w a r d s w o r k i n g i n g r o u p s b a s e d o n p r e v i o u s e x p e r i e n c e s o f t h e w o r k i n g f o r m, and the meaning and consequences of the phenomenon. Secondary aim: to explore differences between those who experience GW and those who do not. In t

Impact of climate change on rice insect pests and their natural enemies

Rice is one of the important staple foods for half of the world population particularly Asian countries for their livelihood, socio-economic and nutrition. Global warming is predicted to increase frequency of precipitation/rainfall, intensity of drought and solar-radiation/UV-B radiation which might affect the intensity and severity of rice pests in one hand, but also change in other friendly arth

Piece-rates and prosperity: evidence from the late nineteenth-century tobacco industry

This paper uses a new and detailed survey of cigar making employers and employees to investigate two related discrimination issues. First, were piece rate cigar makers – the skilled aristocracy of this industry – paid differently by gender? We find that they were, but that the differences can be more than explained by differences in characteristics such as age and experience. Second, we ask whethe

Intracerebral grafting of neuronal cell suspensions. III. Activaty of intrastriatal nigral suspension implants as assessed by measurements of dopamine synthesis and metabolism

The activity of intrastriatal grafts of nigral cell suspensions has been monitored biochemically, using radioenzymatic assays of dopamine, its major acidic metabolite, DOPAC, and DOPA accumulation after DOPA-decarboxylase inhibition. Implants of 4-9 microliter of nigral cell suspension restored striatal DA levels by an average of 13-18%, with the highest individual values reaching about 50% of con

The effect of microstructure and nonlinear stress on anisotropic seismic velocities

Recent work in hydrocarbon reservoir monitoring has focused on developing coupled geomechanical/fluid-flow simulations to allow production-related geomechanical effects, such as compaction and subsidence, to be included in reservoir models. To predict realistic time-lapse seismic signatures, generation of appropriate elastic models from geomechanical output is required. These elastic models should

Layered space-time structure with statistical rate allocation

We propose a modified layered structure for multiple-input multiple-output (MIMO) systems, where the layer detection order is fixed and the data rate for each layer is allocated based on the detection order and channel statistics. With Gaussian approximation of layer capacities, we derive the optimum data rate allocation and the amount of backoff from mean layer capacity is proportional to the sta
