This paper is one detailed research of the major river basins of the Romanian North Dobrogea, Taita River Catchment. The Taita River has a catchment size of about 591 km 2 and is flowing into the Black Sea through Topraichioi Lake after 57 km. Upstream it has an elevation about 240 m height and 0 m at downstream (the reference is the Black Sea). The complexity of this research study is given, on the one hand, by the descriptive side of the natural aspects (geological, morphological, climatic aspects, hydrology and the soil) and, on the other hand, by the practical side, boosted by the information system processing of data. This study presents the theoretical concepts concerning the hazards and the risk, which, for a better interpretation of the impact of these phenomena, are supplemented by the maps, graphs and photographs.

The tribal aristocracy in The Golden Horde Khanate and its successors, shaped by the steppe culture, developed with the elements inherited from the ancient heritage of geography. Since the Asian Hun State, the legacy of four numbers, which has come to the forefront in political, military and social life, has found its place in the name of the Four Beys System / Four Karaçu Beys. The four beys system has become one of the essential elements of the administration in addition to the Khanate position in the Crimean Khanate. The beginning of this system is based on the 4000 soldiers given to Cuçi in the land and tribal division made by Genghis Khan to his sons and the Kıyat, Seycut, Kinhit and Hüşin tribes to which they belong. Although the Mongolian tribes, which were a few in number in the ancient Turkish homeland of Cumania, they tried to keep the rule under the leadership of the Kıyat, and lost their authority after the silence of the Ak Orda (White Horde) dynasty. With the leadership that changed hands between the Mangit and the Sirins, the intertribal balance of power was transferred to the Sirin, Barın, Argin, Kipchak and Mangit tribes under the leadership of the Sirins, who played an active role in the establishment of the Crimean Khanate. The Tribes played an active role in both, internal and external affairs of the Crimean Khanate under the chief Karaçu of the Sirin tribe. After the Crimean Khanate came under the Ottoman protection, the Karachu beys, on the one hand, became the assurance of the Genghisids to hold the throne, on the other hand, they became the control element of power of the Genghisids. The Karachu beys’ keeping the interests of their tribes above everything, has turned the relations in the north of the Black Sea into a slippery ground where the balances were constantly changing.

The study examines the results of complex geophysical research of threearchaeological sites located near the southern part of the Black Sea coastline in Bulgaria:Propadnalata Voda, Atiya, and Alepu. The authors discuss the use of complex geophysical methodsin archaeology depending on the objectives of archaeological research, on the one hand, and thelikely properties of the archaeological sites, on the other. As known, the methods of appliedgeophysics involve reverse geophysical problems, which do not have definitive solutions. Toovercome potential ambiguities in this regard, the study demonstrates how the complementary useof different methods makes the interpretation of the final results easier.

This book examines the impact that Athenian Old Comedy had on Greek writers of the Imperial era. It is generally acknowledged that Imperial-era Greeks responded to Athenian Old Comedy in one of two ways: either as a treasure trove of Atticisms, or as a genre defined by and repudiated for its aggressive humor. Worthy of further consideration, however, is how both approaches, and particularly the latter one that relegated Old Comedy to the fringes of the literary canon, led authors to engage with the ironic and self-reflexive humor of Aristophanes, Eupolis, and Cratinus. Authors ranging from serious moralizers (Plutarch and Aelius Aristides) to comic writers in their own right (Lucian, Alciphron), to other figures not often associated with Old Comedy (Libanius) adopted aspects of the genre to negotiate power struggles, facilitate literary and sophistic rivalries, and provide a model for autobiographical writing. To varying degrees, these writers wove recognizable features of the genre (e.g., the parabasis, its agonistic language, the stage biographies of the individual poets) into their writings. The image of Old Comedy that emerges from this time is that of a genre in transition. It was, on the one hand, with the exception of Aristophanes’s extant plays, on the verge of being almost completely lost; on the other hand, its reputation and several of its most characteristic elements were being renegotiated and reinvented.

The variety described here is Pontic Greek (ISO 639 name: pnt), and specifically the variety that originates from Trapezounta in Asia Minor (present-day Trabzon in Turkey) as spoken today in Etoloakarnania, Greece by second-generation refugees. The term ‘Pontic Greek’ (in Greek: ) was originally an etic term, while Pontians called their language by other names, mainly [ɾoˈmeika] ‘Romeika’ (Sitaridou 2016) but also [laziˈka] ‘Laz language’ (Drettas 1997: 19, 620), even though Pontians and Laz people do not share the same language, the latter being Caucasian. Nowadays, is the standard term used not only by researchers, but also by native speakers of Pontic Greek born in Greece to refer to their variety (but see Sitaridou 2013 for Romeyka in the Black Sea). Pontic Greek belongs to the Asia Minor Greek group along with other varieties, such as Cappadocian Greek (e.g. Horrocks 2010: 398–404; Sitaridou 2014: 31). According to Sitaridou (2014, 2016), on the basis of historical reconstruction, the Pontic branch of Asia Minor Greek is claimed to have been divided into two major dialectal groups: Pontic Greek as spoken by Christians until the 20th century in Turkey and Romeyka as spoken by Muslims to date in Turkey. Triantafyllidis (1938/1981: 288) divides Pontic varieties, as were spoken in Asia Minor, into three dialectal groups, namely Oinountian, Chaldiot, and Trapezountian, the latter consisting of the varieties that were spoken at Trapezounta, Kerasounta, Rizounta, Sourmena, Ofis, Livera, Tripolis, and Matsouka in Asia Minor (Trabzon, Giresun, Sürmene, Of, Yazlık, Tirebolu, and Maçka respectively in present-day Turkey). However, Triantafyllidis does not explain his criteria for this classification (Chatzissavidis 2012). According to one other classification (Papadopoulos 1955: 17–18; Papadopoulos 1958: $\upzeta$ ), the variety that was used in Trapezounta belongs to the dialectal group in which post-stressed /i/ and /u/ delete along other varieties, such as e.g. the ones that were spoken in Chaldia (present-day Gümüşhane), Sourmena, and Ofis (as opposed to the rest of Pontic varieties, such as the one of Kerasounta, in which those vowels are retained). Trapezountian Pontic Greek can also be classified with the group of varieties that retain word-final /n/, such as the varieties of Kerasounta and Chaldia, as opposed to the varieties that do not retain it, such as the ones of Oinoe (present-day Ünye) and (partially) Ofis (Papadopoulos 1958: θ).

Traditionally and socially, the tourism in Constanta is considered to be important to the local economy. Sun and beach locations are both a draw for locals and tourists to the city, on the Black Sea. However, vacation-oriented activities in the city only have a seasonal cycle. In this paper, we proposed to analyze the mass tourist activity in Constanta, taking into account economic, social, and environmental conditions. Additionally, we attempted to build a model based on the data available. The model was developed using a PESTEL analysis to determine the supportability factor of the indicators identified. We also set out to create a projection of the activities proposed for analysis by 2050. To create a model for coastal areas, the data used in this research must be accurate and consistent. Furthermore, correctly identifying indicators and their relationships is a critical step in conducting a thorough study. Last but not least, finding the calculation coefficient for the activity in question is critical, as collecting data from various activities might be challenging when trying to find a feasible model.

Anthropogenic impact on lithodynamics of the coastal zone changes the natural dynamics of bottom sediments, which leads to increased abrasion and swelling of beaches, activation of landslide processes creating a threat of destruction of the coastal infrastructure. The article aims at providing an overview of the scientific literature on the anthropogenic impact on lithodynamics of the coastal zone of the southern and western coasts of the Black Sea (shores of Romania, Bulgaria and Turkey). The work shows that with all the differences in the natural conditions of the coastal zones of these countries the types of anthropogenic effects they undergo are almost the same. These include: hydrotechnical construction without regard to the impact on the neighbouring coast sections; reduction of solid river flow due to river regulation by reservoirs; construction of capital facilities directly on the beaches; illegal extraction of sand from beaches and river beds; dredging with sale of the extracted material to construction companies; covering of cliffs by various structures; destruction of coastal dunes, etc. The main negative consequences of these actions are reflected in disruption of natural dynamics and shortages of bottom sediments, changes in the coastline, reduced aesthetic attractiveness and accessibility of shores, destruction of coastal ecosystems. The article also provides information on the legislation of these countries regarding environmental management in the coastal zone

I look at the impact of Zen Buddhism on western painters during the 1950s and 1960s, focusing on the monochrome in particular, in order to create a historical context for the consideration of transcultural dialogue in relation to contemporary painting. I argue that a consideration of Zen can offer a ‘middle way’ between conceptions of the monochrome (and art in general) often hobbled by models of interpretation that function within a binary opposition between ‘literalist/sensory’ on the one hand, and ‘intellectual/non-sensory’ readings on the other.

This article addresses the legal framework pertaining to navigation in the Black Sea (including the Turkish Straits System) – which is currently one of the busiest trade routes globally – and its implications for the protection and preservation of the marine environment in this region. This framework is a comprehensive and complex system that is based, on the one hand, upon norms established by different global diplomatic conferences and international organizations that are therefore also applicable to the Black Sea and its coastal States; on the other hand, the regional cooperation fora for the Black Sea have also created specific standards for the region. In addition, the implications of the delimitation of maritime areas in the Black Sea and the international responsibility of States in the field of marine pollution caused by navigation will also be examined.

This thesis seeks to answer the question 'when, how, and why the Danish asylum system become more restrictive than the Swedish one between 1989 and 2001'. In the analysis of these reasons, a particular emphasis is placed on the different political perceptions of both countries’ welfare philosophies on the one hand, and their political culture on the other. The influence of anti-immigration parties on mainstream political culture is an important part of this analysis. Through a distinction between border and integration policy, it becomes clear that the Danish asylum policy becomes more restrictive in the second half of the 1990s, because of its focus on cultural integration as a duty to the welfare state. The thesis concludes with a discussion regarding the impact of (neoliberal) economic changes on solidarity within political culture.
