Driving factors for attracting creative knowledge workers in the Amsterdam metropolitan area. The views of high-skilled employees, managers and transnational migrants

This report is a synthesis of three previous studies which analysed the attractiveness of the Amsterdam Metropolitan Area (AMA) for three groups: creative knowledge workers and graduates, managers in selected creative knowledge industries and transnational migrants in the creative knowledge industry who are working in the creative knowledge sectors. The studies were conducted between July 2007 and December 2008. One of the main aims of all three studies was to tease out of the proposed growing importance of the creative knowledge workers goes in hand with a change of the evaluation of the location factors in metropolitan regions. Florida proposed in his books a presentation that Amsterdam can be seen as a model for the future development. It is a compact city which oriented towards cycling. It has one of the highest shares of foreign population. Looking at the path development of Amsterdam, we also expected that the AMA would score high on soft factors like tolerance and diversity. The results, however, bring other points to the fore. Still, the labour market is reported to be the most important factor. This is followed by other hard factors such as the availability of educational institutions and the situation of the housing market. The latter, however, works as a push factor. Since not all creative knowledge workers can be conceived as affluent and especially starters, creative workers and also some groups of transnational migrants (PhDstudents) receive about average income, some groups of the creative knowledge workers are sensitive in this respect. The housing market in Amsterdam in particular is divided between a large, inexpensive social housing segment which is not accessible for most of the average earning creative knowledge workers and a small segment of expensive private sectors housing. The evaluation of the soft factors showed that soft factors alone hardly motivate creative knowledge workers to accommodate in Amsterdam. Also the named soft factors often vary between the groups. Unexpectedly, the importance of personal trajectories and personal networks was often reported as one of the most important reasons to live, work and stay in the AMA. Florida appears to construct our temporary society as fluent and he portrays the individuals as socially and spatially independent. The results of the studies however show that the embeddedness of persons in a local and regional life world with strong personal ties is a more accurate portrayal of the contemporary society in the AMA

Case studies: the environmental impact of DSM projects

Abstract: The critical electricity supply situation in South Africa has brought about the implementation of DSM projects in various industries including the gold mines. However, in certain cases, this may have a negative impact on the environment. As a result of this problem a need to maximise load shifting results with minimal environmental impact has become imperative. This paper presents a study of the possible impact on the environment when attempting load shifting

Het lijkt een wet van Meden en Perzen: in tijden van crisis duikt ook steeds een roep om ingrijpende verandering op. Constante in deze dynamiek is het concept van de rechtvaardige stad. Hoewel al in de jaren zeventig geïntroduceerd, is het nog steeds onderdeel van verhit debat. In deze AGORA een historische en theoretische refl ectie en een analyse van rechtvaardigheid in de stedelijke praktijk

Sustainable urban development is a critical issue in the Netherlands. The country is densely populated, which causes conflicts between environmental concerns and spatial development. Environmental policy integration is proposed as a way to improve the integration of environmental values into spatial planning with the help of learning processes. This chapter evaluates the extent to which the combination of a map-based touch table and an area-specific environmental profile are of added value to environmental policy integration. The case study is the application of the map-based touch table, called MapTable® for the development of a sustainable neighborhood in the region of Utrecht, the Netherlands. It was found that MapTable® facilitates learning processes by providing a platform for communication among stakeholders from different backgrounds. Nonetheless, it must be ensured that all stakeholders are equally included, and that the process suits the application of a map-based touch table in combination with an area-specific environmental profile

Role of dispersion of vanadia on SBA-15 in the oxidative dehydrogenation of propane

A series of vanadia catalysts supported on the mesoporous silica SBA-15 are synthesized using an automated laboratory reactor. The catalysts contain from 0.6 up to 13.6V atoms/nm2 and are structurally characterized by various techniques (BET, XRD, SEM, TEM, Raman, IR, UV/Vis). Samples containing up to 3.1V/nm2 are structurally rather similar. They all contain a mixture of tetrahedral (VOx)n species, both monomeric and oligomeric. The ratio of monomeric and oligomeric species depends on the vanadia loading. At the highest loading of 13.6V/nm2, in addition to tetrahedral (VOx)n, also substantial amounts of three-dimensional, bulk-like V2O5 are present in the catalyst. The structural similarity of the low-loaded catalysts is reflected in their alike catalytical activity during the oxidative dehydrogenation (ODH) of propane between 380 and 480 °C. Propene, CO, and CO2 are formed as reaction products, while neither the formation of ethene nor acrolein or acrylic acid is observed in other than trace amounts. The activation energy for ODH of propane is not, vert, similar140 kJ/mol. The catalyst with the highest loading yields varying activation energies for different reaction conditions, which is probably related to rearrangements between bulk-like and dispersed, two-dimensional (VOx)n. Rather than the monomer to oligomer ratio, the ratio of two-dimensional to three-dimensional vanadia seems to be crucial for the catalytic properties of silica supported vanadia in the ODH of propane
