Building upon the ideas first exposed by Theil and Finizza (1971) and Fuchs (1975), this paper presents an additively decomposable segregation index based on the entropy concept used in information theory. For any pair of classification variables in a given year, the index is decomposed into a between-group and a withingroup term. To analyze intertemporal changes in gender segregation for a giv...

dx. The construction of the schemes involves an appropriate extension of Eyre’s idea of convex-concave decomposition of the energy functional. As an application, we derive unconditionally stable and convergent schemes for epitaxial film growth models with slope selection (F (y) = 1 4 (|y| − 1)) and without slope selection (F (y) = − 1 2 ln(1 + |y|)). We conclude the paper with some preliminary ...

An aggregation rule maps each profile of individual strict preference orderings over a set of alternatives into a social ordering over that set. We call such a rule strategyproof if misreporting one’s preference never produces a different social ordering that is between the original ordering and one’s own preference. After describing two examples of manipulable rules, we study in some detail th...

This paper introduces a conditional extreme value volatility estimator (EVT) based on highfrequency returns. The relative performance of the EVT is compared with the discrete-time GARCH and implied volatility models for 1-day and 20-day-ahead forecasts of realized volatility. This is also a first attempt towards detecting any time-series variation in extreme value distributions using high-frequ...

In the Internet Age, the notion that a traditional classroom with face-to-face instruction, by itself, is no longer adequate for higher education teaching and learning as one that has considerable intrinsic merit. Institutions of higher education, therefore, realize that lecture-based teaching methods alone will not prepare students for the challenges they will face. The State University of New...

The objective of this study is to measure regional income inequalities in Japan in the postwar period by using the weighted coefficient of variation and the Theil T index and explore factors determining regional income inequalities by using several inequality decomposition techniques. Regional inequality in per capita GDP, as measured by the weighted coefficient of variation, first increased an...

Exploring the spatial and temporal dynamic characteristics of regional forest net primary productivity (NPP) in context global climate change can not only provide a theoretical basis for terrestrial carbon cycle studies, but also data support medium- long-term sustainable management planning forests. In this study, we took Shaoguan City, Guangdong Province, China as study area, used Landsat ima...
