Abstract In this study trends in extreme rainfall over the Iberian Peninsula at a daily scale in the second half of the twentieth century have been detected and analyzed. For this goal 35 stations evenly distributed over the region of study covering the period 1958–97 have been studied. Two different approaches have been used. The first one consists of the nonparametric Mann–Kendall test and the Sen method. The second approach is based on the statistical theory of extreme values, involving time-dependent parameters in order to be able to reflect possible temporal changes in the frequency distribution. Results from both methods agree, confirming the reliability of the analysis. Negative trends are found for the west and southwest of the Iberian Peninsula in spring and winter. In autumn a spatial dipolar pattern appears, but trends are not so evident.

Abstract A peaks-over-threshold (POT) approach is used to study trends in extreme rainfall over the Iberian Peninsula (IP) at a daily scale. Records from 52 observatories regularly distributed over Iberia with no missing data were available for the common period from 1958 to 2004. The POT approach was used because it is particularly effective at extracting information concerning true extreme events. A generalized Pareto distribution fit was made to the data involving time-dependent parameters to account for possible temporal changes in the frequency distribution. These parameters were analyzed for trends in the return-level period, of importance for engineering purposes. A time-varying threshold was defined and an automatic declustering scheme was used to select independent extreme events exceeding the threshold. The results indicate a high variability of extreme events over the coastline of the IP, greater over the Mediterranean coast than over the Atlantic coast. The calculation of the trends for the 2-yr return level yielded a large proportion of negative trends for all three seasons considered: 58% for winter, 63% for spring, and 69% for autumn. The parametric approach also revealed an increase in the area with a positive trend of the 20-yr return level relative to the 2-yr return period, especially in autumn in the east of the IP.

This book is devoted to the life and academic legacy of Mustafa Badawi who transformed the study of modern Arabic literature in the second half of the twentieth century. Prior to the 1960s the study of Arabic literature, both classical and modern, had barely been emancipated from the academic approaches of orientalism. The appointment of Badawi as Oxford University's first lecturer in modern Arabic literature changed the face of this subject as Badawi showed, through his teaching and research, that Arabic literature was making vibrant contributions to global culture and thought. Part biography, part collection of critical essays, this book celebrates Badawi's immense contribution to the field and explores his role as a public intellectual in the Arab world and the west.

While today the Ethnographic Museum of the Pilsen Region represents just one of the departments of the Museum of West Bohemia in Pilsen, at the beginning of the twentieth century, in 1915, it emerged as an independent institution devoted to a study of life in the Pilsen region. Ladislav Lábek, the founder and long-time director, bears the greatest credit for this museum. This study presents PhDr. Marie Ulčová, who joined the museum shortly after the Second World War and in 1963 replaced Mr. Lábek on his imaginary throne. The main objective of this article is to introduce the personality of Marie Ulčová and to evaluate the activity of this Pilsen ethnographer and the museum employee with an emphasis on her work in the Ethnographic Museum of the Pilsen Region. The basic aspects of the ethnographic activities, not only of Marie Ulčová but also of the Ethnographic Museum of the Pilsen Region in the years 1963–1988, are described through her professional and popularising articles, archival sources and contemporary periodicals.

On December 22, 2017 the Ukrainian Diplomatic Service marked the 100thanniversary of its establishment and development. In dedication to such a momentous event, the Department of International Relations of Yuriy Fedkovych Chernivtsi National University has published a book of IR Dept’s ardent activity since its establishment. It includes information both in Ukrainian and English on the backbone of the collective and their versatile activities, achievements and prospects for the future. The author delves into retracing the course of the history of Ukrainian Diplomacy formation and development. The author highlights the roots of its formation, reconsidering a long way of its development that coincided with the formation of basic elements of Ukrainian statehood that came into existence as a result of the war of national liberation – the Ukrainian Central Rada (the Central Council of Ukraine). Later, the Ukrainian or so-called State the Hetmanate was under study. The Directorat (Directory) of Ukraine, being a provisional collegiate revolutionary state committee of the Ukrainian People’s Republic, was given a thorough study. Of particular interest for the research are diplomatic activities of the West Ukrainian People`s Republic. Noteworthy, the author emphasizes on the Ukrainian Socialist Soviet Republic’s foreign policy, forced by the Bolshevist Russia. A further important implication is both the challenges of the Ukrainian statehood establishing and Ukraine’s functioning as a state, first and foremost, stemmed from the immaturity and conscience-unawareness of the Ukrainian society, that, ultimately, has led to the fact, that throughout the twentieth century Ukraine as a statehood, being incorporated into the Soviet Union, could hardly be recognized as a sovereign state. Our research suggests that since the beginning of the Ukrainian Diplomacy establishment and its further evolution, it used to be unprecedentedly fabricated and forged. On a wider level, the research is devoted to centennial fight of Ukraine against Russian violence and aggression since the WWI, when in 1917 the Russian Bolsheviks, headed by Lenin, started real Russian war against Ukraine. Apropos, in the about-a-year-negotiation run, Ukraine, eventually, failed to become sovereign. Remarkably, Ukraine finally gained its independence just in late twentieth century. Nowadays, Russia still regards Ukraine as a part of its own strategic orbit,waging out a carrot-and-stick battle.

Levantine Art in the “Orientalizing” Period

The “Orientalizing period” represents a scholarly designation used to describe the eighth and seventh centuries bce when regions in Greece, Italy, and farther west witnessed a flourishing of arts and cultures attributed to contact with cultural areas to the east—in particular that of the Phoenicians. This chapter surveys Orientalizing as an intellectual and historiographic concept and reconsiders the role of purportedly Phoenician arts within the existing scholarly narratives. The Orientalizing period should be understood as a construct of nineteenth- and twentieth-century scholarship that was structured around a false dichotomy between the Orient (the East) and the West. The designation “Phoenician” has a similarly complex historiographic past rooted in ancient Greek stereotyping that has profoundly shaped modern scholarly interpretations. This chapter argues that the luxury arts most often credited as agents of Orientalization—most prominent among them being carved ivories, decorated metal bowls, and engraved tridacna shells—cannot be exclusively associated with a Phoenician cultural origin, thus calling into question the primacy of the Phoenicians in Orientalizing processes. Each of these types of objects appears to have a much broader production sphere than is indicated by the attribute as Phoenician. In addition, the notion of unidirectional influences flowing from east to west is challenged, and instead concepts of connectivity and networking are proposed as more useful frameworks for approaching the problem of cultural relations during the early part of the first millennium bce.

Cyclical Pattern

The decline in numbers of religious in the West is discussed in numerous studies. While there is a consensus about the statistical reality of decreasing numbers, scholars disagree about the alleged reasons for this decline. This article maps the field and presents a survey of four categories of answers to the question of why religious life declined during the twentieth century. A distinction is made between theories that ascribe the decline to (1) historical, (2) societal, (3) ecclesial, and (4) theological reasons. The first category views the decline as part of a historical-cyclical pattern of growth and decline. The second encompasses explanations that focus on secularization, professionalization, or new societal opportunities for women. Thirdly, post-conciliar church-organizational reasons will be discussed. Finally, pre-conciliar theology is investigated as a potential reason for the decline. While none of the reasons discussed here can be excluded from at least contributing to the decline, we demonstrate that some authors are mistaken in their conclusions due to misinterpreting data in a way that obscures the possibility of an emerging decline before the statistics peak in 1965 (which marks the end of the Council). We also demonstrate how theology has been an underestimated but significant influence on the statistics of religious life.

Madura subject to a high level of flood hazard. One of the main causes of flood is extreme rainfall. Global warming generates changes in the amount of extreme rainfall. This research is conducted to identify and to analyze the trends, changes, and randomness of 24-hour extreme rainfall data on Madura Island. The method used is a non-parametric method which includes the Median Crossing test, the Mann-Kendall test, and the Rank-Sum test at the significance level of α =0.05. The analysis was carried out on 31 rain gauge stations. The recording period observed is between 1991-2015. The results of the analysis show that based on the Median Crossing test, most rainfall stations have data originating from random processes. The result shows also that the maximum 24-hour extreme rainfall trend is significantly decreased in a few locations, while for the majority of other stations have no experience a significant trend.
