The study presents the contributions of Raina Katsarova (1901-1984) - one of the pioneers in establishing the Bulgarian traditional music in the first specializated music programs on Rodno Radio and Radio Sofia. It presents a researcher with experience in field work and thousands of recordings of traditional music, with publications of song collections and academic works, but also a citizen, cultural figure, public activist, media figure. The activities of Raina Katsarova as an educator, music journalist and media critic are discussed; her talks and song tales on the radio; her activities in defense of faith and rituals in the media of totalitarian Bulgaria; her role in publicizing Bulgarian traditional music on air around the world as an ambassador of Bulgarian culture, folklore and science. It is concluded that the traces of her activity in the media cover the history of Bulgarian radio, understood in the middle of the twentieth century as a public good and cultural force. It is clear to everyone that music on the radio matters. Raina Katsarova's radio appearances show how ethnomusicology is also important in and for radio.

In the proposed text is sought to answer the question of whether and when we can talk about serialization in the international information flow. An attempt has been made for some systematization of the possible types of serialization, among which the anniversaries stand out. There are two major branches – the traditional serialization and the one generated by the possibilities of new technologies. The example with the ‘Tiananmen Papers’ is considered in more detail. It is also worth noting the borrowing serialization, shown in two examples of connecting processes in the present with such from the recent or very distant past.

The work presents the results of research on the relations between assemblages of carpologicalremains and contemporary vegetation in four small water reservoirs. The main aimof the conducted research was to determine to what extent the assemblages of carpologicalremains preserved in the top layer of bottom sediment of the presently growing vegetationand which factors have crucial influence on the formation of taphocenoses. The author hasbeen trying to answer the following questions: 1. Can the anthropogenic water reservoirsconstitute model objects for the examination of the processes that result in the formationof floral taphocenoses of macroremains? 2. To what extent does the species composition ofassemblages of carpological remains reflect the species composition of the presently growingvegetation? 3. Does the amount of diaspores of particular species found in sedimentspecimens reflect the ratio of their amount/overlay in the contemporary phytocoenoses or, atleast does the number of diasporas reflect the domination of particular species in individualgroups? 4. Which factors determine the arrangement and number of carpological remainsin small and shallow water reservoirs?

The paper considers the specific problem of the land property outside Italy in the Roman provinces during the period of the late Roman Republic and the early Principate. The author studies how the Roman government faced the new problems that the conquest created and what Rome actually did when first met the Hellenistic concepts of the land property in the conquered territories and how they were applied or modified according to the traditional Roman law principles and regulations. It is emphasized that the need to organize the territory and to define the property of the people who lived on that territory or the rights which they had to the land for a very first time occurred in Sicily which the Romans organized as the first Roman provincia. The article examines the organization of Sicily according to Lex Hieronica, it considers the exemptions and immunities of some cities from the general legal regime of the province, and studies the collection of public revenues and the payments for the taxes for the exploitation of the land – vectigal et vectigalia publica. Key notions and terms like possessio, dominium, mancipatio, vectigal, vectigalia, tributum, stipendium are cleared and special attention is paid to the correct use of the Latin legal terminology. Some of the most important fragments from the Institutes of Gaius about the provincial property are examined and is made a carefully study of his language and the legal aspects of his consideration of the rights that the individuals had over the provincial lands. The research presents in details the organization of other provinces in the late Roman Republic and the early Principate and deals with the richest Roman province – Asia, which brings huge revenues to the Roman budget. Central part of the study is dedicated to the legal regime of the provincial land and the author considers the main opinions on this topic in the recent Roman legal doctrine and translates and analyzes the relevant classical Latin texts in the sources and provides an important bibliography on the problem, he tries also to define the Roman concept for „provincial property“ which for sure was not identical with the dominium ex iure Quiritium in Italy.

Klizišta koja su se reaktivirala, kao i brojna druga koja su nastala usljed obilnih padavina i poplava u maju 2014. godine ponovo su ukazala široj javnosti na katastrofalne i svestrane posljedice ove nepogode. Klizanje tla je već odavno postalo naš svakidašnji problem. Sa svojim “nekonačnim obilježjem” u kontekstu drugih prirodnih katastrofa, klizišta nisu samo jezovita u trenucima kada se događaju nego i godinama poslije, kada se zbrajaju učinjene štete i pokušavaju sanirati posljedice katastrofe. Prirodne nesreće pokazuju zapravo da čovjek u borbi sa silama prirode i dalje gubi bitke. Nemaran i pogrešan odnos prema zakonima prirode je jedan od najčešćih i glavnih uzroka koji dovode do pojave klizišta, pa je čovjek postao prirodi najveći neprijatelj. Jedino od čega možemo početi smo mi sami. Ima li naše krivnje zbog bespravne gradnje, neadekvatne vodovodne i kanalizacione mreže, neplanske sječe, pljačke i devastacije naših šuma, divljih deponija? Jesu li regulisana korita naših potoka i rijeka, čiste li se odvodni kanali, šahtovi, odvodni propusti ispod puteva i pruga? Šta mi možemo učiniti da spriječimo i saniramo klizanje terena? Zašto je važna planska gradnja, pošumljavanje, planska sječa šuma, zauzdavanje i kanalisanje oborinskih voda... Prevencija je uvijek jeftinija od liječenja, odnosno otklanjanja posljedica. Nekad su se redovno pošumljavale ledine i proplanci. Oduvijek se prema vegetaciji moglo prepoznati da li je tlo izloženo vlazi ili suši. Niko se ne može porediti sa žednom bukvom koja dnevno može popiti 4-6 litara vode iz zemlje. Može i čovjek, ali ne iz zemlje, a čovjeka ne možemo posaditi. Ratni uslovi i velike migracije stanovništva dovele su i do bespravne gradnje tako da su klizišta postala i posebna socio-ekonomska i ekološka kategorija. Priprema dopunjenog izdanja Priručnika ostvarena je u okviru projekta TPO Fondacije Sarajevo "Psihosocijalna pomoć u BiH" koji se realizira u saradnji sa Volonterskim centrom Univerziteta u Tuzli, s namjerom da se na jednostavan, brz, ispravan i razumljiv način stanovništvo obuči u načinu življenja na terenima ugroženim klizištem. Priručnik ukazuje na mehanizam nastanka klizišta, uzroke koji mogu dovesti i doprinijeti pokretanju zemljanih masa, kao i preventivne mjere koje je potrebno preduzeti u cilju sprečavanja i otklanjanja štete. Namjera autora je bila približiti pojam klizišta običnom žitelju, podučiti ga kako prepoznati klizište, te predložiti praktične mjere prevencije, kao i privremenu sanaciju zemlje oko kuće, radionice, štale, njive, voćnjaka. Građevinska dozvola nije garancija da tlo neće kliznuti. Ko namjerava graditi objekat na padini, trebao bi prethodno uraditi odgovarajuća istraživanja. Takva gradnja jeste skuplja, ali je sigurnija. Ovo nije Priručnik po sistemu “uradi sam” u svakoj prilici i svugdje. Problemi klizanja su složeni pa se za svaki slučaj većih klizanja preporučuje traženje stručne pomoći specijaliste, kako ne bi bili ugroženi ljudski životi i materijalna dobra.
