Participation and Productiviy: A Comparison of Worker Cooperatives and Conventional Firms in the Plywood Industry

A PERENNIAL ISSUE in the study of organizational behavior is the impact on productivity of participation by workers in a firm's decisionmaking. The question has returned to the foreground in the recent debate over policies to increase U.S. productivity growth.' A large literature is aimed at quantifying the impact of worker participation on productivity though the results from this research fal...

Characteristics of products from fast pyrolysis of fractions of waste square timber and ordinary plywood using a fluidized bed reactor.

Fractions of waste square timber and waste ordinary plywood were pyrolyzed in a pyrolysis plant equipped with a fluidized bed reactor and a dual char separation system. The maximum bio-oil yield of about 65 wt.% was obtained at reaction temperatures of 450-500 °C for both feed materials. For quantitative analysis of bio-oil, the relative response factor (RRF) of each component was calculated us...

Materializing a Design with Plywood

This paper is presentation of resulting physical models that were used to explore the relationship between design modeling in CAD and digital fabrication with plywood sheets. We explored a process in making tabletop models with digital fabrication machines and thin plywood sheets. Each was built from combination of predetermined wood joining techniques and structures. These models are believed ...

Biological monitoring of benzene exposure for process operators during ordinary activity in the upstream petroleum industry.

This study characterized the exposure of crude oil process operators to benzene and related aromatics during ordinary activity and investigated whether the operators take up benzene at this level of exposure. We performed the study on a fixed, integrated oil and gas production facility on Norway's continental shelf. The study population included 12 operators and 9 referents. We measured persona...
