Agricultural R&D investment intensity: A misleading conventional measure and a new intensity index

Semantic Intensity: a measure of visual relevance

This work deals with the quantification of the effects of discarding large amounts of irrelevant information in sets of images. In particular, the trade-off between the cost of losing information and the benefit of increasing perceptual speed is examined. We look for a measure of such trade-off by a new measure, 'semantic intensity', broadly defined as the ratio of amount of 'meaning' conveyed ...

Net Reclassification Index: a Misleading Measure of Prediction Improvement

Landscape development intensity index.

The condition of landscapes and the ecological communities within them is strongly related to levels of human activity. Human-dominated land uses and especially the intensity of the uses can affect adjacent ecological communities through direct, secondary, and cumulative impacts. Using land use data and a development-intensity measure derived from energy use per unit area, an index of Landscape...

Investment Timing and Intensity under Progressive Taxation

This paper examines a firm’s investment intensity and timing decisions using a real options approach. The firm is endowed with a perpetual option to invest in a project at any time by incurring an irreversible investment cost at that instant. The amount of the irreversible investment cost determines the intensity of investment with decreasing returns to scale. The project generates a stream of ...

A Change in Energy Intensity: Test of Relationship between Energy Intensity and Income in Iran

In this paper we study the long- term trend of energy intensity for Iran. We use a quadratic function of the logarithm of income to take account of the change in trend of energy intensity and test the non-monotonic relationship between energy intensity and income during 1967- 2002 We find that the long-run coefficient on squared income is negative and significant, indicating a change in trend o...
