This paper uses a meta-Malmquist index for measuring productivity change of the water industry in England and Wales and compares this to the traditional Malmquist index. The meta-Malmquist index computes productivity change with reference to a meta-frontier, it is computationally simpler and it is circular. The analysis covers all 22 UK water companies in existence in 2007, using data over the ...

Meta-regression models are commonly used to synthesize and compare effect sizes. Unfortunately, traditional meta-regression methods are ill-equipped to handle the complex and often unknown correlations among non-independent effect sizes. Robust variance estimation (RVE) is a recently proposed meta-analytic method for dealing with dependent effect sizes. The robumeta package provides functions f...

Since more and more interactions take place between humans and different user-adapted applications in daily life, there is the great opportunity to acquire a lot of knowledge about a user and use it in order to reach a better adaptation. A common vision states that user model should be interoperable and shareable across user-adaptive applications in different contexts and environments. The core...

In this work we summarize some recent results, to be included in a forthcoming paper [1]. We define μ-density as a characteristic of quality for the kind of coverings codes called multiple coverings of the farthest-off points (MCF). A concept of multiple saturating sets ((ρ, μ)-saturating sets) in projective spaces PG(N, q) is introduced. A fundamental relationship of these sets with MCF is sho...

In this paper we study residual solvability of the amalgamated product of two finitely generated free groups, in the case of doubles. We find conditions where this kind of structure is residually solvable, and show that in general this is not the case. However this kind of structure is always meta-residually-solvable.

At present, a single viable population of endangered African wild dogs occurs in South Africa, in the Kruger National Park. Current conservation efforts focus on reintroducing wild dogs into a series of fenced reserves, thereby creating a meta-population in which sub-populations are actively managed to conserve genetic diversity. Additional options exist for conserving wild dogs outside protect...

In this paper, we propose a multimedia script language named ́Meta Scriptμ, which describes the structures of movies based on the counterpoint theory in music. As a case study, we describe a structure of Bach·s ́3 Part Invention No. 4μ with Meta Script, and produce a movie according to the script. From this experiment, we confirm that Meta Script works well as a counterpoint structure descripti...

Since the mid-1980s, the Dutch government has placed increasing emphasis on crime prevention to curb the rising crime rate. New local, regional and national projects have been Implemented. Some significant developments In terms of processes and outcomes of the crime prevention efforts are reviewed. Four examples of successful projects are discussed (prevention of shopping center deterioration, ...
