Abstract Recent literature on the tectonic evolution of the Alpine chain in eastern Europe and Asia Minor is reviewed. Two major periods are recognized in describing the tectonic history of the region. The first embraces all the Paleozoic, ending with the Hercynian orogeny, and probably represents an early period of geosynclinal evolution. The second period is represented by a geosynclinal stage, including the Mesozoic and part of the Paleogene up to the end of the Oligocene, and a terminal stage of orogenesis embracing the Neogene and Quaternary. The geosynclinal stage of the second period can be divided into three phases--an early phase embracing the Triassic, lower and middle and perhaps the upper Jurassic and Cretaceous, and characterized by formation of the first Triassic basins on the peneplaned Paleozoic landscape; a second phase, Cretaceous-middle Eocene, characterized by enlargement of the geosynclines and deposition of flysch; and a third phase which began after the end of the middle Eocene, characterized by closing of the geosynclines. Oceanic trenches which developed in the Black Sea and the southern Caspian, Marmara, Aegean, Ionian and eastern Mediterranean seas are recent structures not connected with the geosynclinal evolution and are superimposed on the continental surface of the geosynclinal structures. The arrangement of the depressions and the uplift during the geosynclinal stage were determined by abyssal faults imposed during the Paleozoic. Magmatic intrusions and volcanism developed in the late geosynclinal phases.

Integrated Ocean Drilling Program (IODP) Expedition 318, Wilkes Land Glacial History, drilled a transect of sites across the Wilkes Land margin of Antarctica to provide a long-term record of the sedimentary archives of Cenozoic Antarctic glaciation and its intimate relationships with global climatic and oceanographic change. The Wilkes Land drilling program was undertaken to constrain the age, nature, and paleoenvironment of the previously only seismically inferred glacial sequences. The expedition (January–March 2010) recovered ~2000 meters of high-quality middle Eocene–Holocene sediments from water depths between 400 m and 4000 m at four sites on the Wilkes Land rise (U1355, U1356, U1359, and U1361) and three sites on the Wilkes Land shelf (U1357, U1358, and U1360). <br><br> These records span ~53 million years of Antarctic history, and the various seismic units (WL-S4–WL-S9) have been successfully dated. The cores reveal the history of the Wilkes Land Antarctic margin from an ice-free “greenhouse” Antarctica, to the first cooling, to the onset and erosional consequences of the first glaciation and the subsequent dynamics of the waxing and waning ice sheets, all the way to thick, unprecedented "tree ring style" records with seasonal resolution of the last deglaciation that began ~10,000 y ago. The cores also reveal details of the tectonic history of the Australo-Antarctic Gulf from 53 Ma, portraying the onset of the second phase of rifting between Australia and Antarctica, to ever-subsiding margins and deepening, to the present continental and ever-widening ocean/continent configuration. <br><br> doi:<a href="http://dx.doi.org/10.2204/iodp.sd.12.02.2011" target="_blank">10.2204/iodp.sd.12.02.2011</a>

Purpose The aim of this study is to evaluate the potential geographic locations for ecotourism activities and to select the best one among alternatives. Design/methodology/approach The proposed model consists of four sequential phases. In the first phase, different geographic criteria are determined based on existing literature, and data are gathered using GIS. On equal criteria weighing, alternative locations are determined using GIS in the second phase. In the third phase, the identified criteria are weighted using analytical hierarchy process (AHP) by various stakeholders of potential ecotourism sites. In the fourth phase, the PROMETHEE method is applied to determine the best alternative based on the weighted criteria. Findings A framework including four sequential steps is proposed. Using real data from the Black Sea region in Turkey, the authors test the applicability of the evaluation approach and compare the best alternative obtained by the proposed method for nine cities in the region. Consequently, west of Sinop, east of Artvin and south of the Black Sea region are determined as very suitable locations for ecotourism. Research limitations/implications The first limitation of the study is considered the number of included criteria. Another limitation is the use of deterministic parameters that do not cope with uncertainty. Further research can be conducted for determining the optimum locations for different types of tourism, e.g. religion tourism, hunting tourism and golf tourism, for effective tourism planning. Practical implications The proposed approach can be applied to all area that cover the considered criteria. The approach has been tested in the Black Sea region (nine cities) in Turkey. Social implications Using the proposed approach, decision-makers can determine locations where environmentally responsible travel to natural areas to enjoy and appreciate nature that promotes conservation have a low visitor impact and provide for beneficially active socioeconomic involvement of local individuals. Originality/value To the best knowledge of the authors, this is the first study which applies a GIS-based multi-criteria decision-making approach for ecotourism site selection.

This chapter examines the competition with the Ottoman Empire and Russia, from the reconquest of Hungary to Joseph II’s final Turkish war. On its southern and eastern frontiers, the Habsburg Monarchy contended with two large land empires: a decaying Ottoman Empire, and a rising Russia determined to extend its influence on the Black Sea littorals and Balkan Peninsula. In balancing these forces, Austria faced two interrelated dangers: the possibility of Russia filling Ottoman power vacuums that Austria itself could not fill, and the potential for crises here, if improperly managed, to fetter Austria’s options for handling graver threats in the west. In dealing with these challenges, Austria deployed a range of tools over the course of the eighteenth century. In the first phase (1690s–1730s), it deployed mobile field armies to alleviate Turkish pressure on the Habsburg heartland before the arrival of significant Russian influence. In the second phase (1740s–70s), Austria used appeasement and militarized borders to ensure quiet in the south while focusing on the life-or-death struggles with Frederick the Great. In the third phase (1770s–90s), it used alliances of restraint to check and keep pace with Russian expansion, and recruit its help in comanaging problems to the north. Together, these techniques provided for a slow but largely effective recessional, in which the House of Austria used cost-effective methods to manage Turkish decline and avoid collisions that would have complicated its more important western struggles.

The tectonic history of the northern flank of the offshore Gippsland Basin can be divided into three phases:an Early Cretaceous rift phase (120-98 Ma) with deposition of the Strzelecki Group and extension in a northeast-southwest direction.a mid-Cretaceous phase (98-80 Ma) with deposition of the Golden Beach Group and extension in a northwest- southeast direction anda Late Cretaceous to Tertiary sag phase with intermittent compression or wrenching.Previous workers have described the first and third phases. This paper argues for a distinctive second phase with extension at right angles to the first phase. The complex Cretaceous structure in the Kipper-Hammerhead area is interpreted in terms of a model in which transfer faults of the first phase became domino faults of the second phase.

The purpose of this chapter is to provide the history of migration of black Africans into Britain and a backdrop for subsequent chapters. An understanding of the migration history of Black Africans is important as it helps us to understand the nature and extent of their entrepreneurial and transnational activity. The conveniently splits into three sections covering three phases or waves of migration covering the period between the 1960s to the beginning of the 21st century. The chapter shows that the reasons and motivation of migration is different with each of the phases of migration. The first phase (1960s – 1970s) consisted of restrained migration from a few African countries namely Nigeria and Ghana and was driven by the desire to acquire education. The second phase (1980s – 1990s) consisted of limited migration from an increased number of countries and still driven by education and some limited refugees. The third phase (Mid 1990s onwards) consisted of unrestrained migration largely driven by economic reasons.

This essay, the first reception history of proto-Pentecostals Johann Christoph Blumhardt and Christoph Friedrich Blumhardt in Anglo-American literature, charts three phases of reception of the Blumhardts in English-speaking circles. The first phase focused on the healing ministry of the elder Blumhardt, which took place primarily in the nineteenth century. The second phase began in the mid-twentieth century and was devoted especially to introducing the Blumhardts to English-speaking readers. It included attempts by theologians and ethicists to appropriate the Blumhardts for constructive theological purposes. The third phase, currently underway, is marked by scholarly assessment of the Blumhardts in their historical setting and by an effort to translate more of the Blumhardt corpus into English. The conclusion offers unsystematic interpretive observations culled from the reception history itself, with an eye to the future appropriation of the Blumhardts in the English-speaking world.

This essay examines the development of the Evangelical Movement in Austria from 1945 to the present. The history of the Evangelical Movement can be divided into four phases: The beginnings (1945-1961), which can be characterized above all by missionary work among ethnic German refugees of the World War II, a second phase from 1961-1981, which can be described as an internationalization of the Evangelical Movement especially through the work of North American missionaries. During this time new ways of evangelism were sought and also church planting projects were started. A third phase is characterized by a growing confessionalization and institutionalization of the Evangelical Movement. While free church congregation were increasingly taking on denominational contours, the evangelical movement as a whole began to increasingly establish its own institutions. The last phase since 1998 is characterized by the Evangelical Movement breaking out of isolation towards social and political acceptance.

Mechanisms of adaptation “to our (Russian) customs” of Italian opera librettos. The paper deals with the history of poetical translation of Italian musical poetry in the 18th century Russia. In particular, it is focused on the question of pereloženie na russkie nravy, the adaptation to national Russian customs, of Italian opera librettos, cantatas, arias, songs and so on. The author points out three different phases of this process. The first phase, in the 1730s, coincides with the reign of Anna Ioannovna and it is linked to Trediakovsky’s translations of Italian intermezzos, comedies and to the first opera seria, La forza dell’amore e dell’odio (‘The force of love and hate’, 1736) by F. Araja and F. Prata; the second phase, in the period 1740–1770s, is characterized by a very varied production of translations and imitations, which undoubtedly influenced the general developing of Russian musical and dramatic poetry. It is during this period that pereloženie na russkie nravy is introduced into dramatic genres and sometimes it is findable in musical poetry as well. The third phase, in the 1780–1790s, is linked with the activity of such poets-translators as Ivan Dmitrevskij, Michail Popov, Vasilij Levšin and is characterized by the new practice of performing operas in Russian translations. In the paper the different forms of pereloženie na russkie nravy are pointed out, starting from the formal niveau of metrics and stylistics up to the adaptation of themes, places and realia.

The history of globalization is intertwined with the history of communication technologies. From a sociological perspective, innovations and developments of both mass media and symbolically generalized media shape the structure of social contacts. Concerning the nexus between globalization and communication, I distinguish three analytically distinct yet partially overlapping phases of globalization: In a first phase, communication became universal by incorporating the globe into networks of exchange, power and belief. In a second phase, communication became instantaneous by means of telecommunication. In a third phase, increasing differentiation within subsystems of society created incentives to communicate across the globe. In their combination, these processes have resulted in the fusion of horizons of meaningful action into a singular global frame of reference. However, that does not imply uniformity since that global frame of frame has also institutionalized a preference for continuous change and variation.
