Seismic uplift of the harbour of ancient Aigeira, Central Greece

The Mavra Litharia cove, between Akrata and Derveni, in the North Peloponnesian coast (Central Greece), has been identified as the site of the harbour of the Hellenistic Aigeira, one of the very few natural harbours along the uplifting, fault-controlled North Peloponnesian coast.
Geomorphological, marine biological and archaeological data as well as radiocarbon dating of marine fossils testify to a 2m relative land uplift since Hellenistic times (around 2000 years bp), part of which (1 m at least) was probably seismic, dated to the Byzantine period (AD 900–1200). This palaeoseismic event, as well as others deduced from archaeological data, are not included in the historical seismology records, but had probably dramatic impacts on the economic and cultural history of ancient Aigeira.
The amplitude of uplift at Mavra Litharia is of the same order of magnitude as submersion dominating the Aegean and, with the exception of the arc, the higher Holocene uplift rate recorded in this area and the surrounding regions. This result is consistent with the Quaternary uplift history of North Peloponnesus.     

The Role of an Area-oriented Approach in Achieving Environmental Policy Integration in the Netherlands,and its Applicability in Bulgaria

An integrated approach to environmental policy and urban spatial planning has not yet been adopted by many local administrations in Europe. However, such integration is likely to provide a more streamlined planning process that incorporates environmental measures in the physical development of urban areas. In this paper, we argue that among many local governments there is already a growing wish to apply environmental policy integration (EPI) principles in spatial planning in an effort to achieve better quality of life in the cities and to preserve natural resources. Within Europe, most attempts to develop EPI approaches can be found in western countries, while efforts to find integrated approaches to the urban environment and spatial planning in Eastern Europe are in their infancy. The main reason for this is that most of the post-communist countries are still addressing the challenge of reconstructing their political, social, and economic systems. In this research, we analyse and compare policy practices for EPI in urban planning in the Netherlands and Bulgaria. We first discuss the Dutch area-oriented policy approach, which has gained popularity during the last decade as a means of integrating environmental qualities in urban land use plans. We then go on to analyse the effectiveness of specific area-oriented methods developed and applied in Rotterdam, and define their applicability in the planning practice of the local authorities of the city of Burgas in Bulgaria. The main conclusion of the study is that the degree of effectiveness of an area-oriented policy is dependent on the impact of specific success factors. Despite the differences between Rotterdam and Burgas in terms of the presence of these success factors, we assert that the area-oriented policy approach applied in Rotterdam can be transferable, and can be adapted to the specific local circumstances in Burgas and used as an instrument for integrating EPI into urban land use planning.     

Flexibility Meets Accountability: State Charter School Laws and Their Influence on the Formation of Charter Schools in the United States

Using an original and unique database of state charter school laws that we have developed, we analyze how state policymakers have incorporated two key values into state charter school laws: flexibility and accountability. We supplement this database with other state‐level measures to answer two specific questions: What factors influence the degree of flexibility and accountability in state charter school laws? How does the content of state charter school laws, and the different values those laws embrace, affect the formation of charter schools in the United States? Overall, we show that state political and contextual factors help account for the degree of flexibility, but not accountability, in state charter school laws. Further, we show that the degree of flexibility, accountability, and political and contextual factors influence the number of charter schools that form in the states.
