Abstract Due to their life-history traits, the petrels are particularly sensitive to predation by introduced species. Therefore, many populations have constricted their original breeding distribution range, currently only occupying predator-free sites. In this scenario, interspecific competition for nesting sites can be detrimental for the petrel’ conservation. Here, we evaluate how the presence of introduced mammals (cats Felis catus and rats Rattus spp.) and potential competitors for nest sites (Cory’s shearwaters Calonectris borealis and feral rock pigeons Columba livia) shape the distribution, breeding density, and breeding performance of the Bulwer’s petrel Bulweria bulwerii on Tenerife, the largest and most densely populated of the Canary Islands. We estimated nest density, assessed the role of nest location and nest characteristics on breeding success, and determined causes of breeding failure by exotic predators and competitors. Nest density was higher in predator-free colonies on marine rocks. Cat presence was the best predictor for nest density, while presence or abundance of competitors had no correlation to nest density. Breeding success varied between years and colonies, but was not related to nest characteristics. Of the unequivocally determined causes of breeding failure, pigeon competition for nests was the most frequent (7.3%), followed by rat predation (6.3%). We also compared petrel and pigeon nest cavities and found a considerable overlap in nesting niche. Our study provides insight on an overlooked impact of the invasive rock pigeon: nest competition with small seabirds. We encourage more research on the effects of pigeons on nest density, disease and pathogen transmission, and vegetation changes within petrel colonies.

The establishment of the socialist regime had led to thorough political, economic, social, cultural and other changes in Bosnia and Herzegovina. The first decade after the Second World War was marked by the reconstruction of the war-torn country, and great support in that process was provided by the USSR - the main ally of the new Yugoslavia. Emphasis was placed on the intensive development of the industry, which was to be the carrier of the overall economic development of the entire country. In accordance with this strategy, large industrial plants were established in all parts of Yugoslavia, thanks to which there was an intensive process of urbanization of numerous previously dormant communities. However, when there was a conflict and then a break with the USSR, Yugoslavia was forced to partially modify its economic development plans (the so-called Five-Year Plans). These changes in Bosnia and Herzegovina were most felt by cities such as Zenica, which instead of the originally planned Doboj became a Yugoslav metallurgical center, and Novi Travnik, which arose as a result of relocating part of the arms industry from Kragujevac in Serbia to central Bosnia. The factory “Bratstvo" (meaning Brotherhood) was built on a deserted meadow near Travnik in the heart of central Bosnia, and for the needs of housing workers who built industrial plants, as well as for those who worked in those plants, the first residential buildings were built in the form of low-quality wooden barracks. These were the roots of the workers' settlement that gradually grew into a new town called Novi Travnik. The fateful link between the factory and the city, which was established at that time, was not interrupted during the entire socialist period, so the survival and development of Novi Travnik completely depended on the business opportunities in the "Bratstvo" factory. The expansion of the production and plant of the "Bratstvo" also included the construction of new housing, communal, social, health, sports, cultural, catering and other facilities in Novi Travnik. A successful business year in "Bratstvo" meant a secure inflow of money into the local community budget as well as a sufficient number of funds for the work of cultural, artistic, entertainment, sports and all other societies in the city. The same rule applied in the case of bad business of "Bratstvo", and the most obvious example of how important the factory was for Novi Travnik can be seen in the case of a failed business in Ghana. The local authorities in Novi Travnik were absolutely aware of the role of the "Brotherhood" in the development of Novi Travnik and tried in every way to facilitate the functioning of the company, so, except for a few mere misunderstandings, relations between city and factory management were mostly friendly. After all, when the survival of the "Bratstvo" was called into question due to the failed business in Ghana, local authorities were among the first to appeal for the company's salvation, clearly noting that with the disappearance of the factory, the fate of Novi Travnik would be sealed. The paper presents a brief overview of the history of the company "Bratstvo" from its founding in June 1949 until the end of the socialist period in 1990, and analyses the relations between the city and factory authorities in that period. The aim of the paper was to show the importance that the factory "Bratstvo" had for the overall development of Novi Travnik and to determine how much the local authorities were aware of the role of companies in the development of the city. The paper provides insight into the processes that took place in a particular local community, but which can also be found in other industrial cities of Bosnia and Herzegovina and Yugoslavia during the socialist period.

The ancient Romans famously distinguished between civic life in Rome and military matters outside the city—a division marked by the pomerium, an abstract religious and legal boundary that was central to the myth of the city's foundation. This book explores, by means of images and texts, how the Romans used social practices and public monuments to assert their capital's distinction from its growing empire, to delimit the proper realms of religion and law from those of war and conquest, and to establish and disseminate so many fundamental Roman institutions across three centuries of imperial rule. The book probes such topics as the appearance in the city of Romans in armor, whether in representation or in life, the role of religious rites on the battlefield, and the military image of Constantine on the arch built in his name. Throughout, the book reveals how, in these instances and others, the ancient ideology of crossing the pomerium reflects the efforts of Romans not only to live up to the ideals they had inherited, but also to reconceive their past and to validate contemporary practices during a time when Rome enjoyed growing dominance in the Mediterranean world. The book explores a problem faced by generations of Romans—how to leave and return to hallowed city ground in the course of building an empire.

<p><em>H</em><em>ousing is derived from the word house</em><em> which means</em><em> a place that has a place to live which will stay or stop in a certain time. Housing is a residence that has been grouped into a place that has facilities and infrastructure. The problem in this study focuses on the type of residential ownership in the form of SHM ART, SHM Non ART, NON SHM and others. </em><em>T</em><em>hese four types</em><em> can be used</em><em> to know the percentage of ownership in all provinces in Indonesia. Due to the fact that there is still a lot of information about the type of certificate ownership, there is still not much ownership. Therefore, the use of the k-Means algorithm as a data mining concept in the form of clusters, where the data already has parameters or values that fall into the category of unsupervised learning. That data produced the best. The data was obtained from published sources of the Republic of Indonesia government agency, namely the Central Statistics Agency data with the category of household processing with self-owned residential buildings purchased from developers or non-developers by province and type of ownership in 2016 throughout Indonesia. In conducting the dataset, researchers used the RapidMiner application as a clustering process application. This research </em><em>shows that</em><em> there are more types of ownership in the SHM ART, but for other values it is still smaller than the value in other types of ownership which is the second largest value. So</em><em>,</em><em> in this case, the role of government in providing assistance in the process of ownership in order to become SHM ART</em><em> is very important</em><em>.</em></p>

The article describes the structural characteristics of the urban communities of the city of Krasnodar and the related features that impact their participation in urban conflicts. This issue is considered in a number of scientific publications, but there is a need to expand the empirical base of such studies. On the base of expert interviews conducted with both city activists, their counterparty (representatives of the municipal government) and external observers (journalists), the parameters of urban communities functioning in the process of their interaction with other conflict actors are revealed. The communities characteristics such as the predominantly territorial principle of formation, the overlap of online and offline communications in their activities, the presence of a “core” with a relatively low number of permanent participants and others are determined. Their activities are dominated by neighborly and civilian models of participation in conflicts. The possibilities of realizing one’s own interests through political interactions (participation in elections, the activities of representative bodies of power, political parties) are not yet sufficiently understood. Urban communities, as a rule, operate within the framework of conventional forms of participation in solving urgent problems, although in some cases it is possible to use confrontational methods, in particular, protest ones. In this regard, the most often used compromise, with the desire for cooperation, a strategy of behavior in interaction with opponents. The limited activating role of conflicts in the activities of communities has been established. The weak manifestation of the civil and especially political component in their activities determines the preservation of a low level of political subjectivity. This factor restrains the growth of urban communities resources and the possibility of applying competitive strategies in interaction with city government and business.
