Generation W: From the young people's perspective

Tekst razmatra poziciju mlade generacije u postpetooktobarskoj Srbiji, onako kako se ona može iščitati iz empirijskog materijala prikupljenog studijom 'Politika i svakodnevni život : Srbija 1999-2002'. Autorka izdvaja četiri osnovna načina samopozicioniranja mladih, pripadnika generacije R, u odnosu na aktuelni društveni kontekst: 'B92 generacija', 'provincijalci', 'fundamentalisti' i 'gosti', pomoću kojih prati promene u stavovima mladih prema politici, sopstvenom socijalnom i političkom angažmanu, pogledu u budućnost, doživljaju samih sebe i socijalne promene kojoj su svedočili ili u njoj participirali.This paper discusses the position of young people in Serbia after October 5th 2000, as can be inferred from the evidence collected in the study 'Politics and everyday life: Serbia 1999-2002'. The author identifies amongst young people four basic modes of self positioning within the current social context, as described by the following labels: 'B92 generation', 'provincials', 'fundamentalists' and 'guests'. These views encompass politics, their own social and political engagement, views of the future, and their own selves

Self-Diffusion in Random-Tiling Quasicrystals

The first explicit realization of the conjecture that phason dynamics leads to self-diffusion in quasicrystals is presented for the icosahedral Ammann tilings. On short time scales, the transport is found to be subdiffusive with the exponent $\beta\approx0.57(1)$, while on long time scales it is consistent with normal diffusion that is up to an order of magnitude larger than in the typical room temperature vacancy-assisted self-diffusion. No simple finite-size scaling is found, suggesting anomalous corrections to normal diffusion, or existence of at least two independent length scales.Comment: 11 pages + 2 figures, COMPRESSED postscript figures available by anonymous ftp to black_hole.physics.ubc.ca directory outgoing/diffuse (use bi for binary mode to transfer), REVTeX 3.0, CTP-TAMU 21/9

The forgotten controversy: Evidence for a world of alternative values

Rad nastoji da promisli jednu zaboravljenu polemiku iz istorije sociološke teorije između dvoje uglednih sociologa, Marijane Veber i Georga Zimela, o položaju žena u nemačkom društvu (i obrazovnom sistemu) početkom 20. veka. Autorke u tekstu nude novu interpretaciju ove polemike koju situiraju u društveni kontekst: (a) nemačkog društva krajem 19. i početkom 20. veka, (b) prvog talasa feminizma u Nemačkoj, i (c) individualnih habitusa glavnih protagonista ove polemike. Interpretacija pokazuje da, uprkos činjenici da se Veber suprotstavlja Zimelovoj hipotezi da bi žene trebalo da stvore drugačiji, nezavisan i alternativan kulturni sistem (subjektivnu kulturu) kao protivtežu dominantnoj muškoj objektivnoj kulturi, oboje pokušavaju da konceptualizuju stvarnost koja bi bila konstruisana na alternativnim sistemima vrednosti. Međutim, ovi konstrukti zamišljenih alternativnih stvarnosti bili su ograničeni akademskim, obrazovnim i političkim iskustvima njihovih tvoraca, kao i njihovom rodnom i klasnom pripadnošću.The paper discuss the forgotten controversy from the history of sociological theory between two eminent sociologists, Marianne Weber and Georg Simmel, about the position of women in German society (and educational system) in early 20th century. The authors offer new interpretation of the controversy embeded into societal context of: (a) German society in late 19th and early 20th century, (b) first wave feminisim in Germany, and (c) individual habitus of its protagonists. The interpretation shows that inspite of the fact that Weber and Simmel confront their opinions about Simmel's hypothesis that women should create a different, independent and alternative cultural system (subjective culture) as a counterpoint to dominant male objective culture, they both made an attempt to conteptualize reality that will be constructed on alternative value systems. However, these alter realities were limited by the academic, educational and political experiences of their creators, as well as their gender and class belonging

Modelling the end of the Acheulean at global and continental levels suggests widespread persistence into the Middle Palaeolithic

AbstractThe Acheulean is the longest cultural tradition ever practised by humans, lasting for over 1.5 million years. Yet, its end has never been accurately dated; only broad 300–150 thousand years ago (Kya) estimates exist. Here we use optimal linear estimation modelling to infer the extinction dates of the Acheulean at global and continental levels. In Africa and the Near East the Acheulean is demonstrated to end between 174 and 166 Kya. In Europe it is inferred to end between 141 and 130 Kya. The Acheulean’s extinction in Asia occurs later (57–53 Kya), while global models vary depending on how archaeological sites are selected (107–29 Kya). These models demonstrate the Acheulean to have remained a distinct cultural tradition long after the inception of Middle Palaeolithic technologies in multiple continental regions. The complexity of this scenario mirrors the increasingly dynamic nature of the Middle Pleistocene hominin fossil record, suggesting contemporaneous hominin populations to have practised distinct stone-tool traditions.</jats:p

Expectations, reality and perspectives in using bim for the green building design

In the late 1970s when the first programs for building energy consumption simulation appeared, architectural practice was based on paper documentation and 2D drafting programs were considered as state of the art technologies. The requirement for 3D building models for computer-based energy simulation minimized the use of this technology in everyday practice. With the appearance of BIM applications that enable creation of information rich 3D building models, everyone expected that this technology can easily provide all data necessary for energy consumption simulation. Today, the market is full of different BIM related applications that are advertised as solutions for the green building design. The paper gives an overview of energy consumption simulation tools and their connection to two BIM applications - ArchiCAD and Revit and demonstrates that recent development of both technologies does not fully meet expectations. The paper indicates means to avoid overoptimistic expectations from software tools that can help designers to achieve better comprehension of the real merits that BIM can bring to green building design. The paper addresses usability of using BIM for sustainable refurbishment. The paper concludes with the analysis of the Semantic Web technologies which can contribute to a better understanding of simulation results, and can provide more information about energy efficiency of the components used in BIM applications' libraries

Bim: Promises and reality

The building information modeling - BIM is a technology developed toward creation of computer based information model that encompasses whole building lifecycle. Toward that goal a number of information technology standards have been developed that enable different professions in AEC to cooperatively develop electronic building model. The paper gives overview of essential technologies, discusses their intended purpose, and gives outline of the currently achieved functionality

Palynomorphological study of dianthus petraeus waldst. Et kit. (caryophyllaceae)

The pollen morphology of Dianthus petraeus (Caryophyllaceae), which is endemic to the Balkans, has been examined by both light and scanning electron microscopy in order to provide taxonomically valuable characters that might be used in the classification of the Caryophyllaceae, as well as to contribute to the pollen atlas of Serbian apiflora. The pollen grains of D. petraeus are radially symmetrical, apolar, spheroidal and medium-sized. The mean of the pollen diameter is 45.5 +/- 1.4 mu m. The sculpturing pattern of exine is microechinate-microperforate, and the tectum is covered with minute echini averaging 0.8 +/- 0.1 mu m in length, more or less evenly distributed between the perforations. The microechini average number per sample area of 5 mu m x 5 mu m is 3.2 +/- 0.6. In view of the number, position and type of the apertures, the grains are polypantoporate, with about 13 operculate pores, averaging 6.4 +/- 0.7 mu m in diameter. Each operculum is covered with 4-6 conical spinules, which are longer than those on the exine surface. The obtained palynological results provide information that contribute towards a better understanding of the taxonomic status of D. petraeus

Overt and hidden curricula in theaching sociology in secondary schools : educational reforms in Serbia (1960-2006)

Teza razmatra problem konstruisanja javnih i skrivenih kurikuluma srednjoškolske nastave sociologije u Srbiji u periodu izmedju 1960. i 2006. godine. Predočena anliza pokušava da rekonstruiše s jedne strane socijalni i politički kontekst društva Srbije, a sa druge obrise sociološke strukovne realnosti i prilika unutar zajednice sociologa u odredjenim istorijskim periodima kako bi razumela realna značenja odredjenih aspekata (javnih i skrivenih) kurikuluma u istorijskom interpretativnom kontekstu unutar koga su oni konstruisani. U analizi je korišćeno nekoliko različitih vrsta empirijskih podataka: (a) zvanični partijski i državni dokumenati relevanti za period i temu koje pokriva ovo istraživanje, (b) različiti zakonski i podzakonski akti kojima je regulisano polje srednjoškolske nastave i preciznije srednjoškolske nastave sociologije u različitim istorijskim periodima koje pokriva ova analiza, (c) raznolika arhivska gradja vezana za rasprave unutar užih strukovnih socioloških krugova, (d) podaci dobijeni iz izvedenih intervjua sa savremenicima neposredno uključenim u proces proizvodnje nastavnih planova i programa sociologije i udžbenika sociologije, i (e) podaci dobijeni analizom srednjoškolskih udžbenika sociologije korišćenih u periodu 1960-2006. Na osnovu ovih različitih vrsta podataka, a uz pomoć metodološkog postupka diskurzivne analize rad mapira tri različita istorijska perioda u kojima su izvršene značajne reformske intervencije u polju srednjoškolske nastave sociologije koji se vezuje za značajne reforme srednjoškolskog obrazovanja, koje su se odigrale (a) krajem 1950tih i početkom 1960tih (reforma gimnazija), (b) krajem 1970tih (reforma usmerenog obrazovanja) i (c) početkom 1990tih (reforma srednjoškolskog obrazovanja potaknuta raspadom bivše jugoslovenske države). Analiza pokazuje da je u ovim različitim istorijskim periodima odnos izmedju različitih aspekata skrivenog kurikuluma (pre svega poruka koje su bile u saglasju sa zahtevima države i političkog sistema i onim koje su proizhodile iz logike struke sociologije i klime unutar strukovne zajednice sociologa) unutar udžbeničkog teksta različito tematizovan. Upravo tematizacija ovog sistemskog protivurečja unutar skrivenog kurikuluma srednjoškolske nastave sociologije otkriva dragocene podatke vezane za istoriju sociologije na ovim prostorima.The thesis addresses the construction of the overt and the hidden curricula of teaching high school sociology subject in Serbia between 1960 and 2006. The analysis hereby presented attempts to reconstruct the social and political context of Serbian society, on the one hand, and the outlines of sociological vocational reality and specific occasions within the sociological community in certain historical periods, on the other. Thus, the thesis strives to contribute to the understanding of the real meaning of certain aspects of (both overt and hidden) curricula in the historical interpretative context within which they were constructed. The analysis has been based on several types of empirical data: (a) the official Party and state documents relevant to the research topic and period covered by the study, (b) the various legal and sub-legal acts that regulate the field of secondary education, and more precisely sociology teaching within secondary education in different historical periods covered by the analysis, (c) diverse archive materials relating to debates within the narrow sociological professional circles, (d) data and findings derived from interviews with contemporaries directly involved in the production of curricula and high school textbooks in sociology, and (e) the data obtained by analysis of high school sociology textbooks used in the period 1960-2006. Based on these different types of data and the use of a methodological procedure of discursive analysis, the presented study maps three different historical periods in which the area of high school sociology teaching has significantly changed. These periods are closely linked to the major reforms of secondary education, which took place (a) in the late 1950s and early 1960s (reform of gymnasia), (b) in the late 1970s (the reform of vocational education) and (c) in the early 1990s (the reform of secondary education inspired by the disintegration of the former Yugoslav state). The analysis shows that in these different historical periods, the relationship between different aspects of the hidden curriculumwithin the textbook narratives has been differently thematized. This particularly refers to the messages that were derived from the requirements of the state and political system, as well as those that were derived from the logic of the sociological profession and the atmosphere within the professional community of sociologists. This thematization of the system’s contradiction within the hidden curriculum of high school sociology teaching reveals valuable evidence about the history of sociology in this region
