The Causality of Supply Relationships
This study examines the 'logic' or underlying causality of supply relationships. It develops and tests hypotheses, in a LISREL model, on detailed data for 553, 450 and 226 supply relationships in the US, Japanese and European automobile industries. The differences found between the three regions seem small, given the received view that there are fundamental differences between 'Japanese' and 'Western' contracting. However, the differences that remain suggest that in the US perhaps the 'Japanese system' has been surpassed, in a 'third way' that combines the advantages of sufficiently durable relations with the advantages of an open system with great variety.Automobile industries;Learning theory;Social exchange theory;Supply relationships;commitment
Enhancement of degradation of fallen apple leaves
Leaves from organic apple trees were dipped with different organic materials and leaves were placed on the orchard floor in autumn. Leaf area and the amount of ascospores of Venturia inaequalis were measured in spring. The objective of this research was to find alternatives for urea that simulate the decomposition of apple leaves and reduces the asco-spore production. In both years urea gave an increase of the leaf degradation and a significant reduction of the number of ascospores. The antagonist Coniothyrium minitans had no significant effect on the ascospore production in both years but decreased the leaf degradation. Beet pulp showed a significant reduction of the number of spores but reduced the leaf degradation rate. Applying extra earthworms increased the degradation
REPCO contribution to the development of products for apple scab control
Natural compounds were sprayed according the RimPro scab warning system from start of bud break until the mid of June. Scab incidence was measured on the leaves and the fruit. Phytotoxicitiy and russet-ing was assessed. The natural compounds were sprayed together with sulphur and were compared with the standard biological fungicides copper hy-droxide and sulphur alone. Compound E73 + sulphur was the most effective on fruit. Armicarb and Resis-tim both sprayed with sulphur were comparable in efficacy with Funguran-OH. In our study laminarin (GL 32) did not shown any effect on the control of scab on apple
Cross-country differences in ICT adoption. A consequence of Culture?
The diffusion of information and communication technology (ICT) has witnessed a surge in the recent years; nevertheless, the rate of adoption across countries diverges considerably. This divergence is observed regardless of the income levels of countries. In this paper, we attempt to explain the differences in ICT adoption rates across countries using Hofstede?s cultural framework. The results suggest that national culture does influence the ICT adoption rate of a country. The results are robust even after controlling for levels of education and income.

Zero-noise extrapolation for quantum-gate error mitigation with identity insertions
Quantum-gate errors are a significant challenge for achieving precision measurements on noisy intermediate-scale quantum (NISQ) computers. This paper focuses on zero-noise extrapolation (ZNE), a technique that can be implemented on existing hardware, studying it in detail and proposing modifications to existing approaches. In particular, we consider identity insertion methods for amplifying noise because they are hardware agnostic. We build a mathematical formalism for studying existing ZNE techniques and show how higher order polynomial extrapolations can be used to systematically reduce depolarizing errors. Furthermore, we introduce a method for amplifying noise that uses far fewer gates than traditional methods. This approach is compared with existing methods for simulated quantum circuits. Comparable or smaller errors are possible with fewer gates, which illustrates the potential for empowering an entirely new class of moderate-depth circuits on near term hardware
