Dynamic data redistribution is used to enhance the performance of an algorithm and to achieve data locality in parallel programs on distributed memory multi-computers. The data redistribution problem has been extensively studied. Previous results focus on reducing index computational cost, schedule computational cost, and message packing/unpacking cost. However, irregular data redistribution is...

Redistribution of specialized molecules in migrating cells develops asymmetry between two opposite cell poles, the leading edge and the uropod. We show that acquisition of a motile phenotype in T lymphocytes results in the asymmetric redistribution of ganglioside GM3- and GM1-enriched raft domains to the leading edge and to the uropod, respectively. This segregation to each cell pole parallels ...

Many scientific applications require array redistribution when the programs run on distributed memory parallel computers. It is essential to use efficient algorithms for redistribution, otherwise the performance of the programs will degrade considerably. The redistribution overheads consist of two parts: index computation and inter-processor communication. If there is no communication schedulin...

Using a laboratory experiment, we examine if third party redistribution from a “Have” to a “Have-not” is affected by (1) whether a Have’s advantage is in some way self-determined and (2) whether selfdetermination occurs in two dimensions compared to one dimension. We find that redistribution decreases if a Have earns an advantageous opportunity or earns income. But we also find that redistribut...

Many important problems in multiagent systems can be seen as resource allocation problems. For such problems, the well-known Vickrey-Clarke-Groves (VCG) mechanism is efficient, incentive compatible, individually rational, and does not incur a deficit. However, the VCG mechanism is not (strongly) budget balanced: generally, the agents’ payments will sum to more than 0. Very recently, several mec...

This paper discusses what determines the preferences of individuals for redistribution. We review the theoretical literature and provide a framework to incorporate various effects previously studied separately in the literature. We then examine empirical evidence for the US, using the General Social Survey, and for a large set of countries, using the World Values Survey. The paper reviews previ...

In this paper we revisit the relationship between democracy, redistribution, and inequality. We first explain the theoretical reasons why democracy is expected to increase redistribution and reduce inequality, and why this expectation may fail to be realized when democracy is captured by the richer segments of the population; when it caters to the preferences of the middle class; or when it ope...

In this paper we study the simultaneous problems of food waste and hunger in the context of the possible solution of food (waste) rescue and redistribution. To this end, we develop an empirical model that can be used in Monte Carlo simulations to study the dynamics of the underlying problem. Our model’s parameters are derived from a unique data set provided by a large food bank and food rescue ...

This paper explores the effect of personal income taxes on redistribution when labour supply reactions are taken into consideration. The results indicate that the classical non-behavioural results on redistribution are not necessarily satisfied in a more general behavioural framework. In this respect, it is shown that the relevant transition to measure redistribution is not the transition from ...

The present paper seeks to explain the pattern of income redistribution in a globalised world of increased market income inequality and lower costs of factor mobility. In some countries, larger market income inequality has been met by an increased redistributive effort, thus keeping the distribution of disposable incomes relatively stable. In other countries, larger market inequality has been a...
