Urban sprawl and its economic, social, and environmental consequences are central issues for approaching more sustainable forms of life and production. This review provides a broad theoretical exploration of the main features of urban sprawl but also of sustainable urban policies in Western Europe and North America. Urban sprawl can be observed in both continents, as the search for higher standards of economic, social, and environmental sustainability is also an essential feature of urban governance in the last years. Urban sprawl has been slightly weaker in Western Europe, as its are cities generally more compact. Moreover, in Western Europe, urban sprawl has sometimes been confronted with ex-ante preventive policies. However, in North America, urban sprawl from the 1950s has been an essential element of the social ordering and, thus, of the American way of life. In both cases, urban sprawl has generated successive rounds of accumulation of built capital, which is currently managed in sustainable ways essentially through ex-post and palliative measures, that is, trying to “sustain what is unsustainable”. In other words, the idea is to make urban sprawl more sustainable but without altering its main morphological elements.

Urban sprawl has become a topical urban issue first in North America and later in Western Europe. It turned into a major challenge to urban sustainability. However, sprawl in Western Europe has displayed many specific features different than that in North America and these features are related to the concrete circumstances in the two continents. The social, economic and urban situation in the new European democracies is also quite different and this inevitably has its impact on the forms of sprawl. One of the main characteristics of sprawl is that it is considered to be market-led. More precisely, a major factor is the lack of balance between market trends and planning policy that allows for the market players to determine the use of their plots in suburban locations with little reference to the public interests and issues of sustainability. As the countries in Eastern and South-eastern Europe have already made certain progress on their way to market society, the problems of sprawl were faced in these countries too. The goal of the paper is to apply widely accepted definitions of sprawl to the processes in the suburbs of Sofia and, thus, to assess whether these are processes of sprawl. It also aims to study the specific traditions and residential preferences of Sofia?s population in order to identify specific characteristics and aspects of the Bulgarian model. The findings of the paper confirm that Bulgaria?s capital Sofia is experiencing processes of urban sprawl, particularly in its southern suburban areas - in the foot of Vitosha Mountain. Next, these processes display strong regional characteristics. So far sprawl in Bulgaria is less intensive than that in Western Europe but also than that in the post-socialist countries in Central Europe and in Baltic states. Eventually, the urban forms of Bulgarian sprawl tend to be denser and with mix of single-family and multi-family residential types and mix of land uses.

The Delta Project is in its final stage. In 1974 it was subjected to political reconsideration, but it is scheduled now for completion in 1987. The final touches are being put to the storm-surge barrier and two compartment dams that divide the Oosterschelde into three areas: one tidal, one with reduced tide, and one a freshwater lake. Compartmentalization will result in 13% of channels, 45% of intertidal flats and 59% of salt marshes being lost. There is a net gain of 7% of shallow-water areas. Human interventions with large scale impacts are not new in the Oosterschelde but the large scale and short time in which these interventions are taking place are, as is the creation of a controlled tidal system. This article focusses on the area with reduced tide and compares resent day and expected characteristics. In this reduced tidal part salt marshes will extend by 30–70%; intertidal flats will erode to a lower level and at their edges, and the area of shallow water will increase by 47%. Biomass production on the intertidal flats will decrease, with consequences for crustaceans, fishes and birds. The maximum number of waders counted on one day and the number of ‘bird-days' will decrease drastically, with negative effects for the wader populations of western Europe. The net area with a hard substratum in the reduced tidal part has more than doubled. Channels will become shallower. Detritus import will not change significantly. Stratification and oxygen depletion will be rare and local. The operation of the storm-surge barrier and the closure strategy chosen are very important for the ecosystem. Two optional closure strategies can be followed without any additional environmental consequences. It was essential to determine a clearly defined plan of action for the whole area, and to make land-use choices from the outset. How this was done is briefly described.

AbstractFrom the late 1950s, Africans seeking higher education went to a rapidly increasing number of destinations, both within Africa and overseas. Based on multi-sited archival research and memoirs, this article shows how Africans forged and used new routes to gain access to higher education denied to them in their territories of origin, and in this way also shaped scholarship policies across the globe. Focusing on British-ruled territories in East Africa, the article establishes the importance of African intermediaries and independent countries as hubs of mobility. The agency of students and intermediaries, as well as official responses, are examined in three interconnected cases: the clandestine ‘Nile route’ from East Africa to Egypt and eastern Europe; the ‘airlifts’ from East Africa to North America; and the ‘exodus’ of African students from the Eastern bloc to western Europe. Although all of these routes were short-lived, they transformed official scholarship provisions, and significantly shaped the postcolonial period in the countries of origin.

Peanut allergens are both stable and potent and are capable of inducing anaphylactic reactions at low concentrations. Consequently, the consumption of peanuts remains the most common cause of food-induced anaphylactic death. Since accidental exposure to peanuts is a common cause of potentially fatal anaphylaxis in peanut-allergic individuals, we tested for the presence of peanut protein in chocolate bars produced in Europe and North America that did not list peanuts as an ingredient. Ninety-two chocolate bars, of which 32 were manufactured in North America and 60 were imported from Europe, were tested by the Veratox assay. None of the 32 North American chocolate products, including 19 with precautionary labeling, contained detectable peanut protein. In contrast, 30.8% of products from western Europe without precautionary labeling contained detectable levels of peanut protein. Sixty-two percent of products from eastern Europe without precautionary labeling contained detectable peanut protein at levels of up to 245 ppm. The absence of precautionary labeling and the absence of the declaration of “peanut” as an ingredient in chocolate bars made in eastern and central Europe were not found to guarantee that these products were actually free of contaminating peanut protein. In contrast, North American manufacturers have attained a consistent level of safety and reliability for peanut-allergic consumers.

And Function

Contemporary public administration reflects its historical roots as well as contemporary ideas about how the public bureaucracy should be organized and function. This book argues that there are administrative traditions that have their roots centuries ago but continue to influence administrative behavior. Further, within Western Europe, North America, and the Antipodes there are four administrative traditions: Anglo-American, Napoleonic, Germanic, and Scandinavian. These are not the only traditions however, and the book also explores administrative traditions in Central and Eastern Europe, Latin America, Asia, and the Islamic world. In addition there is a discussion of how administrative traditions of the colonial powers influenced contemporary administration in Africa. These discussions of tradition and persistence also are discussed in light of the numerous attempts to reform and change public administration.
