The interaction between artists’ professional training and employment in the field of Finnish theatre

This paper deals with the effects of formal training on artists’ employment situation in the 1990s. The empirical data is based on a survey of theatre and dance artists which was done by the Arts Council of Finland in co-operation with the Finnish Theatre Academy. The survey studied current employment status of theatre artists as well as the effects of formal training on their employment, working conditions and salary. The results of the survey have been published in Finnish by the Arts Council (Karhunen, 1994). Copyright Kluwer Academic Publishers 1996labour-market, professional theatre training, employment,

Local Labor Market Adjustment to Immigration: The Roles of Participation and the Short Run

While previous research has generally found that immigration raises unemployment for natives, effects are often more muted than expected. Anticipated out-migration responses have been similarly difficult to discern. However, these findings may be byproducts of the long-run nature of most inquiries, which furthermore do not account for changes in natives' labor force participation. In response, this study evaluates the impact of the arrival of low-skilled immigrants on low-skilled natives in urban areas over a five year period. Initial static results from the Census Basic Monthly Survey clearly indicate that immigrants have a significant negative impact on natives' labor force participation. Building upon these static panel results, characteristics of immigrants' destination choices are examined along with the ensuing adjustment process through dynamic analyses of local markets. Surges of immigrants significantly reduce the labor force participation of low-skilled natives, emphasizing this often neglected channel for labor market adjustment. Previous work may thus understate the true impact of immigrants on local labor markets by focusing on the longer term and ignoring adjustments through participation.

Rhizodeposition and the enhanced mineralization of 2,4-dichlorophenoxyacetic acid in soil from the Trifolium pratense rhizosphere

Enhanced biodegradation of organic xenobiotic compounds in the rhizosphere is frequently recorded although the specific mechanisms are poorly understood. We have shown that the mineralization of 2,4-dichlorophenoxyacetic acid (2,4-D) is enhanced in soil collected from the rhizosphere of Trifolium pratense[e.g. maximum mineralization rate=7.9 days-1 and time at maximum rate (t1)=16.7 days for 12-day-old T. pratense soil in comparison with 4.7 days-1 and 25.4 days, respectively, for non-planted controls). The purpose of this study was to gain a better understanding of the plant-microbe interactions involved in rhizosphere-enhanced biodegradation by narrowing down the identity of the T. pratense rhizodeposit responsible for stimulating the microbial mineralization of 2,4-D. Specifically, we investigated the distribution of the stimulatory component(s) among rhizodeposit fractions (exudates or root debris) and the influence of soil properties and plant species on its production. Production of the stimulatory rhizodeposit was dependent on soil pH (e.g. t1 for roots grown at pH 6.5 was significantly lower than for those grown at pH 4.4) but independent of soil inorganic N concentration. Most strikingly, the stimulatory rhizodeposit was only produced by T. pratense grown in non-sterile soil and was present in both exudates and root debris. Comparison of the effect of root debris from plant species (three each) from the classes monocotyledon, dicotyledon (non-legume) and dicotyledon (legume) revealed that legumes had by far the greatest positive impact on 2,4-D mineralization kinetics. We discuss the significance of these findings with respect to legume-rhizobia interactions in the rhizosphere

Social and political barriers to the use of Marine Protected Areas for conservation and fishery management in Melanesia

In this paper we examine the strengths and weaknesses of state-supported Customary Marine Tenure (CMT) systems in two independent Melanesian states (Solomon Islands and Papua New Guinea) in the context of the management of rapidly intensifying commercial and subsistence fisheries. We focus particularly on the proposed use of permanent no-take Marine Protected Areas (MPAs), which are at present strongly favoured by scientists and environmentalists around the world, as the most versatile marine fishery management tool, especially in poor developing countries. We argue that, with some exceptions, typical Melanesian CMT regimes make MPAs difficult to establish, primarily due to issues of scale. We look closely at the ecological rationale for no-take MPAs, for different coral-reef based species, and assess the likelihood that populations of these species are self-replacing on the same scale as CMT territories for most of coastal PNG and Solomon Islands. We argue that with some exceptions (mainly species with short-lived larvae), the dynamics and scale of population replacement processes for most fished species make no-take permanent closures largely incompatible with traditional CMT systems, and therefore unlikely to prove a successful management tool in this socio-political context
