There is more and more empirical evidence to show that highly skilled people are an important determinant of economic growth. Consequently, policy-makers are eager to keep their graduates in the region or attract graduates from elsewhere. It is also well known that people with a higher level of education exhibit high rates of spatial mobility. Much less is known about mobility patterns according to discipline and academic grade. Do the best people stay or leave, and does this vary according to discipline and type of region? This paper investigates the relationship between ability, field of study and spatial mobility using a micro‐dataset on Dutch university and college graduates. The findings indicate that there are substantial net flows mainly towards the economic centre of the Netherlands, but that there are also flows between peripheral regions and to other countries. The paper finds that university graduates are more spatially mobile than vocational college level graduates and that when one looks at spatial behaviour according to discipline, there are also striking differences between graduates. This, however, does not necessarily mean that peripheral regions also lose their best graduates. For several disciplines, employers in the peripheral areas are able to retain the graduates with the highest grades, contrary to what the standard human capital framework predicts. However, the study finds that if graduates leave the region, those with the highest grades are more likely to move abroad.Migration , higher educated graduates , human capital , the Netherlands , periphery , multinominal logit ,

This paper looks into the connection between population change, and population decline in particular, and the rates of new firm formation. Although it is clear that fewer people will eventually lead to fewer (new) firms, we assess whether this negative relationship differs with different rates of population change and across regional contexts. Population decline occurs in different types of regional context, which could also lead to different outcomes. In this study we distinguish between urban and rural areas.In order to establish the impact of population change, and population decline in particular, on entrepreneurship, this paper examines data on population density, size, growth and decline, together with firm dynamics for the period 2003-2009, retrieved from the LISA database. In general, the results show that the relationship between entrepreneurship and population change depends heavily on the regional context. When assessing different levels of population change, we find that its relationship with entrepreneurship depends strongly on the regional context. The results indicate that urban regions tend to experience strong negative impacts as a result of population change, while the impact on rural regions remains positive. In conclusion, we find clear differences in the intensity of the impact of population change on new firm formation according to the type of region. The regional context and the intensity of decline must be taken into account when determining the kind of coping mechanism needed to deal with the consequences of decline.

The inheritance of flower colour in diploid potato (2 n = 2x = 24), was found to be controlled by three unlinked loci D, F and P. To determine the allelism with previously described loci and to dissect this oligogenic trait, a set of tester clones with well-defined genotypes was developed. By backcrossing the mapping population with these tester clones it was possible to obtain monogenic segregation ratios. These were required to detect linkage with RFLP loci and, despite distorted Mendelian ratios, the inheritance and mapping of the D, F and P loci could be unambiguously determined. Locus D, involved in the biosynthesis of red anthocyanins, was mapped on chromosome 2, while locus P, involved in the production of blue anthocyanins, was mapped on chromosome 11. Locus F, involved in the flower-specific expression of gene(s) accommodated by the D and P loci, was mapped on chromosome 10. The tester clones and the map position of the D, F and P loci may be of considerable value in simplifying the genetics of anthocyanin pigmentation.

a b s t r a c tThe Wadden Sea is one of the largest intertidal areas in the world and has been designated as a UNESCO World Heritage Site in recognition of its unique natural features. Major changes in the morphology and ecology of the Wadden Sea over the past millennium resulted from increasing anthropogenic influences such as coastal protection, land claim from the sea and drainage of wetland for agriculture, exploitation of natural resources from hunting and fishing to the extraction of groundwater, gas and oil, industrialisation at port locations and tourism at the islands. A sustainable future can only be achieved if policy and management are backed by solid science. Many of the anticipated changes result from the upscaling of pressures on the Wadden Sea system. Economic globalization leads to upscaling of fisheries, tourism and industrial activities, and thus to changed pressures on space and nature. Climate change will lead to changes in hydrographic patterns, species distribution and possibly tourism; through sea-level rise it will put pressure on coastal protection and the extent of intertidal areas. Invasions of exotic species will transform the ecosystem. There are three major related challenges to management: 1. Nature conservation in a changing system requires a focus on preservation of the values and not the state of the system; 2. The adaptation of the management structure to the scale increase of the pressures, so that local and regional management becomes better nested in transregional and transnational governance structures; 3. Finally, the management approach needs to deal with increasing uncertainty in external forcing of the system, as well as with nonlinearities in system dynamics when it is pushed outside its normal range of operation. Based on these pressures and management challenges, we advocate an integrated social-ecological systems approach for the scientific study and the science-based management of the Wadden Sea Region. The essential characteristics of this approach are strong interdisciplinarity and a focus on aspects of scale and cumulative processes.

This study examines the occurrence and spatial patterns of creative industries in the context of a developing country, specifically Indonesia. Our findings show that, in the context of Indonesia, it is crucial to distinguish between 'innovative' creative industries and 'traditional cultural' industries. The first category represents those that exploit new knowledge and intellectual property. The latter industries tend to preserve heritage values as selling points and, in Indonesia, they are actually much more significant in economic terms than creative industries and therefore should be taken into account. The spatial patterns of the two industries also differ. Creative industries are likely to concentrate in large urban regions, where innovation and cross-fertilisation of ideas can take place with the support of talent pooling and relatedness among niche producers. The Indonesian case is no exception. Meanwhile, traditional cultural industries are much less dependent on human capital and urbanisation economies. The results of this study suggest that policy strategies aimed at creative industries would be applicable in reasonably advanced regions provided they have sufficient human capital and economic diversification. In comparison, regions specialising in traditional cultural industries can adopt a different strategy to optimise the impact of these industries. Currently, the creative industry policy does not make this distinction.
