Mineral Economy:An International Comparison

An International Comparison

This research describes, classifies, and comparatively evaluates national models and mechanisms used to evaluate research and allocate research funding in 16 countries. Although these models and mechanisms vary widely in terms of how research is evaluated and financed, nearly all share the common characteristic of relating funding to some measure of past performance. Each of these 16 national m...

Unhealthy Behaviours: An International Comparison

In the current global economy, chronic non-communicable diseases (NCDs) have become the leading cause of death and a major health concern for both developed and developing countries. Among other factors, the worldwide spread of NCDs is driven by the globalisation of unhealthy habits. The purpose of this paper is to develop a simple statistic to measure, at the national level, the average popula...

Iran Railway Efficiency Analysis, Using DEA: An International Comparison

Efficiency measurement is critical for industries where firms do not face strong competition, as we cannot rely on the market to discipline the firms' efficiency. Railway is a typical example. At the same time the fact that railway produces multiple outputs using the common set of inputs calls for a delicate and sophisticated treatment in measuring the efficiencies. In this article, the DEA ...

Comparison of AVIRIS and Hyperion for Hyperspectral Mineral Mapping

1.0 Introduction The 0.4 to 2.5 μm spectral range provides abundant information about many important Earth-surface minerals (Clark et al., 1990). In particular, the 2.0 to 2.5 μm spectral range covers spectral features of hydroxyl-bearing minerals, sulfates, and carbonates common to many geologic units and hydrothermal alteration assemblages. Imaging Spectrometers, or “Hyperspectral” sensors pr...
