Abstract The aim of this paper is to provide empirical evidence for the statement that the constraints imposed on an objective function are able to reduce the entropy of the corresponding distributions produced by entropy-maximizing models. This idea is evaluated via an application to an entropy-maximizing spatial interaction model, as a typical representative of the family of entropy-maximizing models used in geography. Eleven versions of this spatial interaction model are fitted separately to six sets of data concerning interregional migration in Slovakia. For each model, the predicted flow distribution is derived, prior to calculation of the corresponding predicted entropy, and then comparison of the entropy values relating to all the models. The results obtained indicate very clearly that constraints imposed on an objective function reduce the initial maximum entropy successively, with this reduction depending on the number and nature of the constraints incorporated.

Abstract This article offers a review of the state and practice of Polish research in the field of urban social geography, which is still under formation. From the outset, this domain has shown marked diversification as regards both subject matter and methodology. Like most “reviews”, this one has its strong subjective elements. The first part presents the historical context, i.e. the political, organisational and social circumstances in which research has been conducted. The roots of research in social geography in Poland trace back to the inter-War period (1918-1939), while post-War evolution of geography (like everything else in the country) reflected the imposed impact of communist-era doctrine. Specifically though, it was the formation of the Institute of Geography as a part of newly-established Polish Academy of Sciences (in 1953) as combined with the methodological conference convened in Osieczna in 1955 that shape geographical research in Poland for several post-War decades. The second part of this paper documents the gradual emergence of urban social geography (under a relatively relaxed political impact where social research was concerned). The implementation of social ecology is stressed, as well as the concept of factorial ecology as a leading toils and initial concepts. Also presented are the processes which have shaped the current state of urban social geography; sources of inspiration from geography, sociology and especially social ecology; and the quantitative turn taken by the social sciences. The third part turns its attention to the diversity of concepts and subject matter present in research on social problems, as well as such phenomena as: socio-spatial differentiation and disparity, poverty, housing issues and cultural dimensions. General mention is also made of the new concepts and research topics which emerged with Poland’s post-1989 transformation, like electoral studies, gentrification, spatial inequality, spatial conflict, the appropriation of public space, regeneration, perception studies and cultural studies. Particular attention has been paid to theoretical concepts relating to cities (as a product of ideology). So theories regarding “the socialist city” (i.e. the communist-era city) and its transformation into the city of the post-communist era were developed, with the current evolution being regarded as dominated by the neo-liberal doctrine. It is concluded that urban social geography in Poland is still under formation, even if it already occupies a relatively good position as applied research, while also returning (culturally) to its more humanistic and socially sensitive roots.

Abstract In recent years, Polish geographers have become increasingly interested in publishing their research results in English-language journals under the ISI Master Journal List (also known as the “Philadelphia List” in Poland). On the one hand, such an interest has arisen out of the desire to disseminate the results of individual or team research; while on the other it reflects the necessity for appropriate output to be calculated, in order that scientific advancement and parametric evaluation of the scientific institute may take place. Against that background, the work presented here has sought to assess the diversification of geographical centres in Poland, on the basis of an analysis of the published output of their independent employees (habilitated doctors and professors). A separate issue is to investigate the academic achievements of independent scientific workers, as regards age group, sub-discipline (physical or socio-economic geography), and scientific status (habilitated doctor or professor). The analyses were based on the bibliographical database within the Web of Sciences Core Collection, as well as Google Scholar. The analysis of bibliometric indicators referring to the work published by independent researchers shows that Poland’s leading geographical institutions are primarily large centres, first and foremost those in which scientists tend to specialise in physical geography. These are centres conducting numerous research projects, engaging in extensive scientific cooperation in Poland and abroad and publishing their own scientific journals. Among the leading geographical institutions are the University of Gdańsk, Jagiellonian University, University of Lódź, Adam Mickiewicz University in Poznań, Institute of Geography and Spatial Organization of the Polish Academy of Sciences, University of Warsaw, University of Wrocław and University of Szczecin. In terms of works published in domestic journals, the two sub-disciplines of geography are characterised by similar bibliometric indicators for an average representative. In contrast, in the case of international journals, there is an evident predominance of those representing physical geography. Conducted analyses also show that physical geographers more often publish as teams. The output of physical geographers is also more universal in character, meaning that extensive use can be made of them in the study of global processes. Socio-economic geographers generally focus their attention on research within the region in which their institution is located, or else deal with social and economic phenomena in their own country. Analysis of bibliometric indicators by age groups of researchers seems to offer optimism for the future. In the case of Google Scholar, older workers present higher values than their younger colleagues, but these differences – apart from citation number that reflect a longer presence on the publishing market – are not very great. However, in the case of the Web of Science, generally offering a better reflection of the level of scientific impact and involvement in international collaboration, young researchers rank higher than their older colleagues. It is therefore to be hoped that their impact in worldwide geography will be greater in the coming years than at present.

Abstract The article presents results of research devoted to the role of the shopping centre as a traffic-generating factor in individual-car transport. The research procedure was conducted in relation to Port Łódź, one of thirteen shopping centres within the boundaries of the Polish city of Łódź. The main aim has been to determine the share of car traffic generated by Port Łódź in the totality of traffic flows in the network of roads leading to the shopping centre. The analysis was based on data from the urban traffic control system or, to be precise, one of its subsystems which has access to information on spatial and time accessibility of the number of vehicles, transmitted from induction loops situated in the network of urban crossroads. The research focuses on defining potential and real traffic generation for weekdays and weekends, as well as during public holidays and festival days. The research allowed for verification of one of the model approaches to the correlation between selected characteristics of shopping centres and the volume of traffic they generate. Results show that shopping centres located along exit roads on the city outskirts affect the road transport system, particularly by exciting car traffic (also during rush hours), retaining it during afternoon rush hours (thus contributing to an alleviation and extension in time) and, to a lesser extent, serving as an informal element of the Park&Ride system (in the case of centres characterised by good accessibility to public transport and a free car park).
