In this paper the concept of tax co-ordination within the European Union (EU) is discussed, in view of the coming enlargement of the EU. The tax externalities that possibly arise in a single market are analysed, as well as the ways these externalities can be prevented or internalised. These theoretical reflections are placed alongside the actual system of tax co-ordination within the EU. Focusi...

Eighteen co-ordination postures with shoulder flexion angles (0°, 45° and 90°) and elbow flexion angles (0°, 45° and 90°) in standing and sitting positions were evaluated to identify the effects of co-ordination postures on maximum grip strength and muscle activities of the upper limb in this study. Thirty-nine subjects were recruited and their maximum grip strengths were measured. According to...

We hypothesized that changes in the pattern of spring precipitation would alter the species composition of a temperate soil-surface collembolan community. Experimental manipulation of precipitation during a drought in southern England was used to test this hypothesis in spring 1997. Replicated plots in a field of spring peas received spring drought (plots shielded from rainfall), reference (act...

Understanding the links between large scale spatial structuring of fish assemblages and shaping factors is essential to develop comprehensive ecosystem-based fisheries management. In this study, we investigated spatial patterns of bottom fish assemblages in the North Sea in relation to prevailing water masses in the region. We based our analysis on catch data from the German Small-Scale Bottom ...

Secondary succession reflects, at least in part, community assembly—the sequences of colonizations and extinctions. These processes in turn are expected to be sensitive to the size of the site undergoing assembly and its location relative to source pools. In this paper we describe patterns of succession over 18 years in an experimentally fragmented landscape created in eastern Kansas, USA, in 1...

Several techniques were used to study the co-ordination of mRNA levels for five constituent chains of cartilage collagen fibrils during mouse development. Short cDNA clones were first constructed for mouse and human alpha3(IX) and for mouse proalpha1(XI) collagen mRNA species. Northern analysis of developing mouse embryos revealed that the mRNA species for alpha1, alpha2 and alpha3 chains of ty...

This prospective, longitudinal study examines individual differences in two conceptually related but empirically distinct domains of social-cognitive competence (cognitive interpretive understanding and interpersonal perspective co-ordination) as moderators of the relation between peer rejection and neglect and behavioral and emotional problems in grades 2 and 3. As expected, peer rejection and...

We prove that for a certain class of co-ordination games with increasing payoffs for co-ordination there are not necessarily pure Nash equilibria. This is achieved by introducing a particular model for the payoffs. This result is in contrast to the congestion game with decreasing payoff. We discuss a generalization of the model introduced which is of independent interest.
