Large group of the natural coastal landslides in the area of Gdynia (Babie Doły, Oksywie and Redłowo) are dominant and cover an area of about 4 ha (i.e. 60% of the area studied). The anthropogenic landslides, on the other hand, are more numerous but not bigger than 0.1 ha and occur within the town area. Cypel Redłowski is the most active cliff of the Bay of Gdańsk. There the erosion causes significant retreat of the coastline. The pace of that backward movement calculated by means of Terrestrial Laser Scanning (TLS), between years 2010 and 2015 was between 0 to almost 5 metres. During the same time the Cypel Redłowski retreated from 81.45 to 81.55 km, i.e. at a pace of 0.23 metres a year. The pace of retreat in the Cypel Oksywski was even faster in the past. There the active landslides caused total damage of the fortifications built at the beginning of the 19th century. Prevention against landslides caused by the marine erosion has been applied for over a hundred years now. The marine erosion is the most significant trigger of the coastal landslides. The intensity of the erosion depends on the frequency of storms. Heavy rains exceeding 100.0 mm per 24 hours also trigger mass movements in the Gdynia area. Such event took place in Gdynia in 2016. At that time a landslide movement causing extensive damage was recorded.

Knowledge of world / European history is important for a more complete understanding of complex processes, for comparisons and placing national and regional history in a broader context that provides more meaningful answers. What determines the course of history is sometimes “a series of smaller events in the midst of the context of big ideas”. The borders of the region are determined by geographical, cultural and geopolitical characteristics, as well as the political interests of those builders whose interpretation has dominance. In expanding or narrowing the territory of the Balkans, politics was usually more decisive than geography. Historical events in that area should be presented from the positions of all its peoples, including Muslim communities. Their narratives also form a legitimate part of the picture of that past. Muslims were not the “favorites” of multiple Balkan historiographies that minimized and marginalized their component, functioning as factors shaping their own national and political ideologies. Historiography does not only deal with the reconstruction of the past, but, with all the difficulties and pitfalls, it also interprets it. A fragmentary study of the destinies of Muslim communities hinders the identification of the broader processes and common denominators of their parcelized history. The processes of de-Ottomanization and Balkanization also led to their particular consciousness within the newly formed, post-Ottoman states. Their historical experience is largely not “condensed, preserved, and generationally transmitted”. The attitude that Muslims are “foreigners” in Europe is part of the mentality and process known as the “Eastern Question”. Minds are not too prone to change. Calling all Muslims “Turks” is not the result of ignorance, but of a concrete attitude. It was not until the Berlin Congress of 1878 that the question of their protection became somewhat relevant. The system of such protection was inadequate, without supervisory mechanisms to control the implementation of commitments. Major political changes most often brought about religious and ethnic changes and displacements in the Balkans. In the study of the decades-long process of formation of the Serbian state in the 19th century in the area of the Smederevo Sandzak and the emigration of Muslims from it, special attention is paid to the fate of two small settlements (Mali Zvornik and Sakar) on the right bank of the Drina. After the surrender of the towns to the Serbs in 1862, only Mali Zvornik and Sakar remained in the hands of the Muslims. The origin of the settlement of Mali Zvornik is connected to the existence of the Zvornik fortress and the town of Zvornik on the left bank of the Drina, which was first mentioned in 1412. Mali Zvornik grew on the right bank of the Drina as part of the town of Zvornik. In the first half of the 18th century, travel writers mention that Mala or Mahala of the Bosnian town of Zvornik, whose inhabitants were called Maholjani, was located there. South of Mali Zvornik lies village of Sakar. In the 19th century, in Mali Zvornik and Sakar, on the border with the Smederevo Sandzak, Muslims made up the majority of the population. As only the Drina separated them from the settlements of Divič and Tabaci on its other side, the inhabitants of these settlements were firmly connected by kinship, friendship and marriage, and they were economically oriented towards each other. The Principality of Serbia was persistent in its demands to get Mali Zvornik and Sakar, having in mind their geostrategic position. By the decision of the Berlin Congress in 1878, they became part of Serbia. Until 1912, these were the only settlements in it with a majority Muslim population. They lost that majority over time. What is conditionally called “local” history, in addition to great narratives, indicates, confirmed by various experiences, the multidimensionality of the past, its features and specifics in a particular area.

The deformation monitoring of the landslide is an important research in the field of slope engineering. The terrestrial laser scanner is frequently applied to the deformation monitoring for landslide risk reduction in recent years. In this paper, the deformation was detected by means of comparison of sequential scanning datasets. And the erosion quantification can be extracted from the deformation. Finally, a preliminary change analysis methodology to distinguish landslide movement from erosion is presented. Our results enable us evaluate the stability of the landslide generally and basically. The application of terrestrial laser scanning to detect the movement and erosion quantification provides us another considerably effective and efficient way in the high-risk landslide deformation monitoring.

Powołane przez Radę Miejską w 1887 r. Archiwum Aktów Dawnych Miasta Krakowa wzbogacało swój zasób dzięki darom przekazywanym przez mieszkańców – zarówno archiwaliów czy muzealiów, jak i książek. Natomiast działające od 1878 r. Krajowe Archiwum Aktów Grodzkich i Ziemskich w Krakowie, podlegające galicyjskim władzom krajowym, zaufanie ofiarodawców zaczęło zyskiwać dopiero po przejęciu w 1919 r. przez władze polskie. Te działania kontynuowało od 1952 r. Wojewódzkie Archiwum Państwowe w Krakowie, powstałe z połączenia obu archiwów (obecnie Archiwum Narodowe w Krakowie). Wspieranie powstających w Krakowie w XIX w. muzeów i bibliotek gromadzących pamiątki minionej świetności Rzeczypospolitej było uznawane za patriotyczny obowiązek, z czasem dawało możliwość zabezpieczenia dla przyszłych pokoleń dokumentów rodzinnych, materiałów wytworzonych przez osoby aktywnie działające na różnych polach czy instytucji lub organizacji, które zakończyły działalność. Archiwum zawsze z wdzięcznością przyjmuje ofiarowywane archiwalia dotyczące Krakowa, Małopolski czy szerzej Galicji, bowiem misją archiwów państwowych jest zachowanie wszelkich materiałów archiwalnych będących źródłem do dziejów Polski i jej mieszkańców. Expansion of archival resources through donations. A contribution to the events of the National Archives in Krakow and its predecessors in the 19th–21st centuries Established by the Town Council in 1887, the Krakow Town Archives of Former Records enriched its resources thanks to donations from inhabitants – both archival materials or museum items, and books. However, operating from 1878, the Local Archives of Records of the Courts for the Nobility in Krakow, under the Galician authorities, only began to obtain the trust of benefactors after it was taken over by Polish authorities in 1919. These activities continued from 1952 in the form of the State Archive of the Krakow Province, founded through a merger of both archives (currently the National Archives in Krakow). Supporting the museums and libraries founded in Krakow in the 19th century that collected souvenirs of the past greatness of the Republic was regarded as a patriotic duty, providing an opportunity to safeguard for future generations family documents, materials created by those active in various fields or institutions and organisations which have ended their activities. The Archives always gratefully accepts donated archival materials connected with Krakow, Malopolska or Galicia, as the mission of the state archives is to store all archival materials that could be a source of information concerning the history of Poland and its inhabitants.

The incompleteness of Victorian census returns of marriage and birth records for England and Wales, and the high costs of using civil and church records, have greatly restricted research into the timing and character of the decline in marital fertility in the second half of the 19th century. This article argues that, in spite of these limitations, the census returns provide enough data to allow the well-known the 'Own-children method of fertility estimation', when used within Bongaarts' framework for analysing the proximate determinants of fertility, to derive estimates of total and age-specific marital fertility for women 15 to 49 years of age. It uses data from the census returns for the town of Rawtenstall, a small cotton textile manufacturing town in north-east Lancashire, to generate these estimates and to test their credibility against other well respected measures of marital fertility for England and Wales.

In a literary heritage with a developed tradition of genres, works whose main purpose is to attract the attention of readers to a selected geographical location, are of particular culture-historical and culture-geographical interest. The most widespread in this respect is travel literature, which is usually written by travellers and consist of impressions portrayed in prose after visits to foreign lands. Another type of literary depiction with an expressed poetic orientation, but a similar goal, is characteristic of dedicatory poetry. The author’s position is usually saturated with emotional expressiveness as well as the artistry of symbols, encouraging the reader or listener to feel the formation of a spontaneous attitude. It is possible to gain confidence in the engagement of the author of the poetry as an individual in the depicted cultural-geographical environment, which can be conceptually expressed by words or pairs of words ‘resident’, ‘native place’, ‘patriot’. With regard to the devotional depictions on the Latvian urban environment, one of the earliest examples known in the history of literature is the dedicatory poem in German by Christian Bornmann to the town Jelgava with its ancient name (Mitau, 1686/1802). The name of Liepāja town in this tradition of the genre has become an embodiment later – in the poetry selection in German, also using the ancient name of the town (Libausche Dichtungen, 1853), but in terms of contemporary literary practice with Imants Kalniņš’ music, there is a convincing dominance of songs with words of poetry. The aim of the article is, looking at the poetry devoted to Liepāja in the 19th century and at the turn of the 20th/21st century in the comparative aspect, to present textually thematic peculiarities as well as to provide the analytical interpretative summary of those.
