An Interactive Approach to the Central Facility Location Problem: Locating Pediatric Hospitals in Warsaw

Most of the conventional approaches to the central facility location problem neglect the interaction of analyst and decision-maker during the locational choice process. This paper presents a new interactive approach to the central facility location problem. It is assumed that the problem is formulated by an analyst as a multiobjective optimization problem. Then the decision-maker searches for a satisfactory solution working directly with the computer system. The interactive procedure was implemented on IBM-PC XT/AT as the decision support system DINAS (Dynamic Interactive Network Analysis System) which enables the solution of various multiobjective location-allocation problems. DINAS has been successfully used for solving a real-world planning problem, namely for finding locations for pediatric hospitals in the Warsaw region.     

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.     

Theory of Comparative Advantage: Do Transportation Costs Matter?

In this paper we present a formal analysis that incorporates returns to transportation into a Ricardian framework to predict trade patterns. The important point gained from this analysis is that increasing returns to transportation, coupled with appropriate distances between trading partners, can be shown to reverse Ricardian predictions even when there are no international differences in tastes, technology, or factor endowments. Additional gains from trade may emerge from reductions in aggregate delivery costs owing to scale economies.     

Peculiarities of sedimentation conditions in the oxbow lakes of Dubysa River (Lithuania)

Abundant wood remains and buried trees have been found in the western part of Lithuania near Zakeli?kiai and Lyduv?nai on Dubysa River (a tributary of Nemunas River) where deposits are rich in organic remnants and buried soils. In Zakeli?kiai and Skiru?iai sections of Dubysa River oxbow sediments were investigated by various methods (dendrochronological, carbonate, granulometric, pollen and mollusc fauna analysis). In addition, these sections were dated using the radiocarbon method. Samples were collected from deposits of Dubysa River outcrops. The studied oxbow lakes have existed for more than 5 thousand years (from ca. 4300 BC to 1000 AD). During this period organic rich deposits with trees and branches were formed in the oxbow lake. This indicates that at the end of Atlantic, during Subboreal and in the early Subatlantic periods there was a forest growing that contained mainly oaks which were falling down into an oxbow lake and later were covered by sandy and silty deposits. The granulometry of alluvial deposits, as well as the mixture of medium-grained sand and silt show different stages of Dubysa River palaeochannel formation: riverbed and oxbow lakes. Three climate warming cycles were revealed according to carbonate analysis data in all investigated sections. The rheophile thermophilous Holocene age molluscs species Bithynia tentaculata L., Unio cf. crassus Philipsson, Pisidium amnicum (Müller), Theodoxus fluviatilis (Linnaeus) have been found. The pollen composition and sequences have been divided into five local pollen assemblage zones (LPAZ) and described according to pollen spectra in each zone. In this way it is possible restore palaeoclimatic coherent evolution, trends and cyclical change.     

When should the Central Europeans Join EMU?

This article first considers why central European countries wish to join EMU soon. The main reasons are the risk of macroeconomic instability they face outside the euro zone if they wish to grow quickly. At the same time, central Europe is highly integrated with regard to trade with EMU, so it is little exposed to asymmetric shocks that would require a realignment of exchange rates. Finally, it is argued that there is no cost in terms of slower growth from EMU accession, so that there is no trade-off, as has been claimed, between nominal convergence to EMU and real convergence to EU average GDP levels. Second, the article assesses whether central European accession to EMU would be disadvantageous to current members. It concludes that accession cannot increase inflationary pressure on existing EMU members, also as claimed, but that slow growing members of EMU might suffer increased unemployment, unless they increase the flexibility of their labour markets. Incumbent members may also be unwilling to share power with central Europeans in EMU institutions.     

Beeswax remnants,phase and major element chemical composition of the bronze age mould from Gaj Oławski (SW Poland)

The recently found metal casting mould from Gaj O?awski (SW Poland) was designed for the production of socketed axes typical for later stages of the Bronze Age in Poland (ca. 1100–900 bc). This unique artefact is a half of a durable, two-piece wedge-shaped mould and measures 17.5?×?7.2?×?4.0 cm. The surface of the mould is covered copper oxides and carbonates, and the remnant of beeswax was found on its inner surface. The metal forming mould consists of cored dendrites of Cu-dominated (Cu >96.5 wt%, up to 2.2 wt% Sn) and Cu impoverished (Cu ~86.0 wt%, Sn ~9.4 wt%, some Sb, As and Ag) end compositions and volumetrically subordinate α?+?δ eutectoid. The “as cast” structure of the metal shows that the mould was never used for molten metal casting. Since this kind of moulds was used for mass casting of metal, the Gaj O?awski one was probably never used, and the beeswax is the remain of its coating. This is the first remain of the Bronze Age beeswax described in metallurgical context in Europe.     

Multi-proxy reconstruction of mire development in the Poręby Wojsławskie ecosystem (Sandomierz Basin, southeastern Poland)

Multi-proxy analysis (sedimentological, palaeobotanical, geochemical data and results of radiocarbon dating) of the biogenic sediments from a small mire ecosystem in the Sandomierz Basin (SE Poland) is presented. The ecosystem contains a full hydroseral sequence from minerotrophic to ombrotrophic wetland. It is one of the few sites in this region which is so thoroughly investigated in terms of the palaeoenvironmental record. Changes in the water supply of the mire area, and consequently the changes in the plant and sediment succession, were well correlated with the regional tendencies in precipitation and temperature during the Late Glacial/Holocene transition and in the Holocene. Human impact is very well recorded in pollen diagram from the Subboreal period.     

Mesolithic fishery in the Polish Lowland. Fish remains from the Site 7 at Krzyż Wielkopolski,Poland

Fish remains have been discovered at seven Mesolithic sites located mainly in central and northern Poland, an area that is known as the Lakeland of the Polish Lowland. Based mainly on the results of the identification of fish remains uncovered during the excavations at the Site 7 in Krzy? Wielkopolski (Western Poland), the conclusions were made on the locality and technique of fishery. The fish taxa represented show that the fishing showed that the fishing economy during the Mesolithic period was focused on nearby freshwater rivers and lakes. At that time, people fished primarily for Cyprinids, pike and perch. According to the archaeological finds, the basic fishing tools used by the Mesolithic communities were spears, harpoons and rods with hooks. The small fishes recovered were most probably caught by fishing traps or nets, but such artifact finds are very rare in the Polish Lowland. This paper summarises the current data on Mesolithic fishery in the Polish Lowland based mainly on the data from the Site 7 at Krzy? Wielkopolski, but also includes archaeological data collected from previous studies in the region.     

The Environmental History of the Holocaust

ABSTRACT

The introduction conceptualizes environmental history of the Holocaust as a subdiscipline of Holocaust studies. The authors approach this emerging field of research through the context of environmental humanities with its current interest in the Anthropocene, soil science, forensics, multispecies collectives, and explorations of relations between ecocides and genocides. Proposed approach considers post-Holocaust spaces and landscapes as specific ecosystems and examines relations between its actors (human and non-human) in order to show the Holocaust’s spatial markers and long-terms effects. The article outlines existing literature on the subject, identifies the central research problems and questions, and discusses sources and methods. The authors demonstrate that the environmental history of the Holocaust applies a hybrid methodology that uses methods from various disciplines with the aim of creating new theories and interpretive categories and thus should be considered complementary to existing approaches in Holocaust studies. The authors follow the methodological principles of grounded theory in generating new concepts and seeking multidisciplinary methods for explaining nature’s role in the Holocaust and how Holocaust has changed nature. The authors claim that environmental history of the Holocaust broadens Holocaust studies as a field of research and opens up new questions concerning relations between nature and extermination in order to provide a more holistic perspective for exploring the relationship between culture and nature, genocide and ecocide. The approach proposed here shows Holocaust and post-Holocaust landscapes in terms of ecological/natural heritage, which might influence the way these spaces are commemorated, conserved and preserved, as well as used for tourist purposes.
