Privacy and False Identification Risk in Geomasking Techniques

Recent years have seen an increase in location privacy research, including the application of geomasking procedures. Geographical masks aim to protect privacy and preserve spatial information through the displacement of point data. False identification, or the mistaken association of data with the incorrect person or household, is an unexplored issue in geomasking, despite legal protections against false association. This study introduces a topological framework for assessing identification risk and examines the risk of false identification in four masking techniques: random perturbation, donut masking, and the newer Voronoi and MGRS masking techniques. While Voronoi masking is found to best preserve the clustering properties of a sample of urban foreclosure data, the other three masking techniques result in better protection against correct and false identification.     

“Lwów Saved Us”: Roma Survival in Lemberg 1941–44

The ritualized memory of genocide has been a cornerstone of Roma political mobilization during at least the last three decades. A uniqueness paradigm has been developing for some time, applying a memorial discourse inspired by the Jewish Holocaust model. While paralleling each other in time, the mass murders of Jews and Roma during the Second World War differed on several points. In the General Government of the Occupied Polish Territories and the territories occupied by Nazi Germany after Operation Barbarossa, the persecution of Roma took place largely in local initiatives. Consequently, the Nazi policies varied considerably, leading to territories in which Roma were annihilated and those in which about half of the Roma population survived. Considerable differences could also appear within the same administrative unit. In Distrikt Galizien, the southeastern-most district of the General Government, Roma were persecuted violently in the countryside, while the district capital of Lemberg (Lwów, Lviv) saw a different course of events. The picture that appears from the available documents also diverges from survivor testimonies and general accounts of the persecution of Roma as being similar and parallel to that of Jews. Roma were present in Lemberg throughout the Nazi occupation and the authorities were aware of their whereabouts. Roma were not confined to the ghetto, but many, along with Poles and Ukrainians, remained within the territory of the ghetto, parts of which had constituted areas of Roma settlement in Lemberg since the mid nineteenth century. Several Roma also lived in wagons in various locations in 1942–43, as well as in quarters close to the town’s centre. Altogether, several hundred Roma lived in Lemberg, and their treatment by the local courts was different from that of Jews, bearing more similarity to the way in which Polish and Ukrainian cases were handled.     

Edward Abramowski's concept of stateless socialism and its impact on progressive social movements in Poland in the twentieth century

The author traces the impact of Abramowski's ideas on the recent history of Poland. His concepts were not only popular in the Polish Socialist Party (PPS) and the syndicalist movement in the interwar period (1918–1939), but they also exerted a profound influence on the cooperative movement and democratic left-wing opposition in the 1970s and 1980s. The leaders of the Workers’ Defence Committee (KOR) were much influenced by Abramowski's ideas and, according to some researchers, the Solidarity movement from 1980 to 1981 in Poland was the culmination of his concepts. Today's anti-systemic movements in Poland (anarchists, syndicalists, alter-globalists) are also inspired by Abramowski. The author also draws attention to certain similarities between Abramowski's ideas, Kropotkin's idea, Gramsci's concept of civil society and the thought of the young Marx. The author also outlines Abramowski's social ideas in the context of ideas promoted by the main theoreticians of the Polish left in the late nineteenth and early twentieth centuries.     

Territorial Keys for Bringing Closer the Territorial Agenda of the EU and Europe 2020

The recent developments of the economic theory suggest that due attention to territorial context increases efficiency and improves delivery of the policies. This in turn calls for better linkages between spatial and socio-economic efforts. The paper analyses the concept of policy territorialization and proposes policy tools for that purpose. The relevant theoretical models are used, mainly evolutionary economics and new economic geography. The key outcome is a set of territorial keys supposed to enhance territorial approach in developmental policies. Also some plausible ways of making use of those keys are proposed and then tested using Polish territory as a case study.     

OSL dating and lithological characteristics of loess deposits from Biały Kościół

Absolute dating using luminescence methods is widely applicable in geology, geomorphology, palaeogeography and in archaeology in establishing ages of sediments and archaeological artefacts. By creating absolute time scales for different events in the history of Earth scientists are able to reconstruct changes in climate and environment in the past, and the history of colonization and development of culture.     

The Kambārī in the Museum of the Frankincense Land,Salalah, Oman

This article examines the kambārī vessel now housed at the Museum of the Frankincense Land, Salalah, Oman, built for display in 1980. This sewn‐plank boat type, used for fishing and lightering in Dhofar, is discussed in the context of other similar vessels in Oman, South Yemen, and Somalia. As one of only five known surviving kambaris, a detailed account of this vessel's construction is given accompanied by an accurate pictoral record.
