Living in the technopolis: Between reality and imagination
Stupar Aleksandra
Spatium , 2008, DOI: 10.2298/spat0818021s
Abstract: Perceived as one of the possible reflections of the contemporary society, the technopolis (or the 'techno-city') integrates the latest technology, various modernist and anti-modernist elements, as well as numerous 'utopian' features which should facilitate our lives and underline aspirations for the future. Consequently, our world, composed of overlapped digital and physical realms, flexible spaces and transformable webs, is balancing between utopia and anti-utopia, progress and decay, geography and non-geography. The stunning, but also horrifying images of the present create tension and confusion, while their fast-changing scales and modes additionally complicate the latest morphing and charting of the global world and its urban nodes. Obviously, the city, as always, depicts the technological background of the society, demonstrating its potentials, paradoxes and threats. However, the modern cities, whose spaces and buildings often represent the wonders of technology, are facing numerous problems. Placed between material and virtual reality, their landscapes are blended and distorted, but colored by similar imperatives and demands. Therefore, the purpose of this paper is to define and analyze the outcomes of the urban/architectural interventions which explicitly or implicitly used modern technologies, generating a stage for the 21st century technopolis. .
Urbs et orbis: (Re)charting the center, (re)positioning the limits
Stupar Aleksandra
Spatium , 2009, DOI: 10.2298/spat0920053s
Abstract: The paper examines the concept of finiteness and its implications on urban space focusing on the relation between urban(ized) environment, social context and spatiotemporal perception. Furthermore, it analyzes and evaluates various roles which the notion of the center and the limit has had through history - representing an inseparable part of traditional city planning or being completely transformed in order to transmit and express contemporary identity. Considered as a residue of a particular mythical narrative and a distinctive feature of the first philosophical speculations, this concept was rooted in primordial technical matrices of archaic and classical cities, but its latest manifestation has distorted previous models. Consequently, the original significance has been manipulated - shaping a new urban geography as a post-modern, multi-scale setting for our future life.
Patchwork or matrix: Testing the capacity of the contemporary city
Stupar Aleksandra,?uki? Aleksandra
Spatium , 2007, DOI: 10.2298/spat0716001s
Abstract: Being exposed to the multiple needs of their contemporary users, the cities from all over the world have been forced to activate all capacities in order to intensify their land use, adjust their urban structure and reinvent some forgotten segments (ex-industrial areas, traffic nodes, docks, waterfronts) as generators of multilayered transformations and mutations. Therefore, the purpose of this paper is to analyze and compare different approaches of this practice, as well as to emphasize the relation between the applied global imperatives/trends/myths, local conditions and limitations, and the outcomes. Consequently, the first part will be structured around four key-words which often "justify" and activate multifunctional and intensive land use - connectivity, profit, identity and sustainability. The second part will be focused on the case of Serbia, describing a unique postmodern example of the fusion of local and global influences. The multifunctional land use in this case is a result of numerous political and economic problems, the plurality of values and (il)legal transformations of urban structure. This condition has finally affected the rising need for urban redesign, the re-organization and revitalization of city centers, fringe areas, devastated and degraded urban zones, as well as the development of existing transport and communication networks i.e. improvement of urban and regional connectivity. Additionally, the "model of territorial values" will be explained as a planning tool which could be used in order to increase the level of urban attractiveness, define urban parameters and estimate land values. .
City vs. climate changes - the future and its (un)sustainability: The global applicability of Sarriguren and J tk saari?
Stupar Aleksandra,Nikezi? Zoran
Spatium , 2011, DOI: 10.2298/spat1126040s
Abstract: The global reality, intensively exposed to the challenges caused by climate changes, demands new ideas, methods and tools which could eventually prevent or mitigate the consequences of carbon emissions. Therefore, the contemporary cities, as focal points of the new global comprehension, have become testing grounds for numerous initiatives based upon imperatives of sustainability, environmental consciousness, energy efficiency and ‘green’ life style. In Serbia, experience in matters of the built environment has had a tendency to be formed exclusively on the basis of authentic local initiatives, aspirations, successes and failures. In the global effort for sustainable development, considering the commitments imposed by climate change and carbon emission, a greater reliance on results achieved elsewhere would be a welcome change. Consequently, this article will present and comment two eco-driven projects - Sarriguren and J tk saari, both covering a wide range of useful ideas, intriguing concepts and globally applicable solutions for the challenges caused by climate shifts.
Chasing the limelight: Belgrade and Istanbul in the global competition
Stupar Aleksandra,Hamamcioglu Cenk
Spatium , 2006, DOI: 10.2298/spat0614027s
Abstract: The purpose of this paper is to analyze and compare main changes of contemporary Belgrade and Istanbul - two urban nodes at the crossroads of different and multileveled flows. Following the same pattern of global activation, inevitable competition and networking, these cities are trying to synchronize their multidimensional background, establish new patterns of global behavior and adjust them to the dynamism of modern life. Consequently, their historical role has been modified, urban tissue has been developed, recreated and regenerated, and the output of this process represents an attractive testimony of their global initiation. Revealing the ambiguous nature of strong economic forces as well as a new fusion of urban cultures, Belgrade and Istanbul are structuring the globalized image with the new key-elements. However, their true potential and the real efficiency of this process should be re-evaluated - the changed physiognomy of the city could improve its position in the global hierarchy and facilitate its integration into the global community, but, sometimes, local limitations are too complex and too strong to be ignored.
Genetic recombination and the origin of mitochondrion
Stupar Milanko
Archive of Oncology , 2003, DOI: 10.2298/aoo0301035s
Abstract: Division of ancestral prokaryotic genome into two circular double-stranded DNA molecules is a basis for future separate evolution of nuclear and mitochondrion compartments. Universal double sheet of lipid molecules by invagination, at the level of membrane-hairpin attachment, formed two-layered envelope completely surrounding those two DNAs. Presumed ancestral prokaryote in this case is an Archaebacteria, which would lead to formation of six main groups of organisms: Archaebacteria (Archaea) eubacteria, Protista, Fungi, Plantae and Animalia.
Nucleogenesis and origin of organelles
Stupar Milanko
Archive of Oncology , 2008, DOI: 10.2298/aoo0804088s
Abstract: Division of the ancestral prokaryotic pragenome into two circular double-stranded DNA molecules by genetic recombination is a base for the future separate evolution of the nuclear and mitochondrial gene compartment. This suggests monophyletic origin of both mitochondrion and nucleus. Presumed organism which genome undergoes genetic recombination has to be searched among an aerobic, oxygen non-producing archaeon with no rigid cell wall, but a plasma membrane. Plastids evolve from an aerobic, oxygen producing proto-eukaryot, after mitoplastide genome duplication and subsequent functional segregation. In this proposal, origin of eukaryots occurs by a three-step mechanism. First, replication fork pauses and collapses generating a breakage in the genome of archaeal ancestor of eukaryots. Second, the double-strand break can be repaired intergenomically by complementary strands invasion. Third, this duplicated genome can be fissioned into two compartments by reciprocal genetic recombination. Scenario is accomplished by aberrant fission of the inner membrane surrounding separately those two compartments.
The idea of European citizen after the 'period of reflection' and the Treaty of Lisbon
Stupar Milorad
Filozofija i Dru?tvo , 2008, DOI: 10.2298/fid0803149s
Abstract: The author analyzes the Reform Treaty and comes to the conclusion that there are changes in the concept of European citizen in it, in the sense that its democratic potential has been enhanced. In showing this the author relies on 'pragmatic model' for understanding individual and collective identity as it was introduced in social science by sociologist Raymond Breton.
The concept of European citizen
Stupar Milorad
Filozofija i Dru?tvo , 2006, DOI: 10.2298/fid0631009s
Abstract: The normative interpretation of the concept of European citizen should be carried out on a utilitarian or pragmatic model rather than on the cultural one. However, the idea of European culture cannot be totally neglected.
