Inequality and development
Inequality can be analyzed from various aspects. In this paper our attention is drawn to economic inequality, most frequently manifested through income and wealth. The measurement of economic inequality is a complex task. The Lorenz curve and a number of numerical indices are applied, and let us mention the following ones: the Gini coefficient, the coefficient of variation, the Theil index and the Atkinson measure. These indices do satisfy the criteria (principles) presenting, according to general consent an appropriate measure of economic inequality: anonymity (symmetry) principle, population principle, relative income principle and the Dalton principle of transfer. In recent times, the problem of inequality has been attracting a lot of attention. The explanation should be sought in the widening of income differences (within individual countries and between them) and also in new knowledge about the relationship between inequality and development. The attitude to inequality being determined mainly by the economic development level (as presented in the Kuznets hypothesis) is gradually being replaced by the attitude to inequality being the determinant of income and its growth. Contrary to previous beliefs about the stronger income inequalities being favorable to the economic growth, more recent research has pointed to the fact that a more equal distribution of income through various channels, can possibly act as an efficient stimulus of growth
Problemi normativne snage i kritike agonistiÄke participacije - ka moguÄoj komplementarnosti agonistiÄke i participativne demokratije
In this article I argue that there are grounds for considering agonistic democracy and participatory democracy complementarity in order to institutionalize agonism which has thus far lacked an elaborate articulation of its institutional dimension. The two democratic theories share a commitment toward widening the scope of the political as a way of inclusion of citizens and their subsequent political subjectivation and empowerment. Furthermore, there are authors on both sides who think democracy does not need foundations. Agonistic participation and contestation, on the one hand, and the broadening and strengthening of various sectors of political participation, on the other, both open up new possibilities for critique and change, but also create new risks. Building on a redefinition of agonisitic participation, I aim to attenuate an objection that agonism is normatively weak in terms of lacking resources to motivate citizens and justify their critique of practices of domination and oppression. The article concludes that we need to embrace agonistic participation as a means towards the development of democratic political judgement, as there are no other guarantees, i.e. secure foundations, for our ability to distinguish between democratic and non-democratic agon.U Älanku se tvrdi da postoje osnovi komplementarnosti agonistiÄke demokratije i participativne demokratije u pogledu moguÄnosti institucionalizacije agonizma koji dosad nije imao razraÄenu institucionalnu dimenziju. Dve demokratske teorije dele težnju za Å”irenjem politiÄkog kao naÄina ukljuÄivanja graÄana i njihove politiÄke subjektivizacije i osnaživanja. TakoÄe, ima autora na obe strane koji dele shvatanje da demokratiji nisu potrebni temelji. AgonistiÄkom participacijom kao osporavanjem, s jedne strane, i Å”irenjem i jaÄanjem razliÄitih oblasti politiÄke participacije, s druge, otvaraju se moguÄnosti za kritiku i promenu, ali se prostor otvara i za rizike. OslanjajuÄi se na redefinisanu agonistiÄku participaciju, želim da ublažim prigovor da agonizam nema normativnu snagu u smislu neposedovanja resursa za motivisanje graÄana i opravdanje njihove kritike praksi dominacije i ugnjetavanja. ZakljuÄak je da je potrebno prihvatiti agonistiÄku participaciju kao sredstvo razvijanja demokratskog politiÄkog rasuÄivanja jer nema drugih garancija, tj. nema sigurnosti temelja, koji bi nam omoguÄili da razlikujemo demokratski od nedemokratskog agona
LiÅ”eni diskursa legitimacije - zazidane zemlje Centralne Evrope i politiÄki subjektiviteti u nastajanju
In this paper I want to compare rare theoretical justifications of border walls with discourses on boundaries and walls by Central and Eastern European political actors in dealing with refugee crisis in 2015. I analyze three such discourses: consequentiality, discourse of responsibility for fair distribution of cosmopolitan duties, and nationalistic discourse. This comparison allows me to question applicability of Wendy Brown's argument that the states with waning sovereignty display symbols of force in building border walls aimed at defending fragile egos built around national and religious identities. Finally, I want to elucidate what type of political subjectivity is produced and legitimated by these acts of fortification within and around CEE 'walled' states.U ovom Älanku želim da uporedim retka teorijska tumaÄenja i opravdanja zidova na granicama sa diskursima o granicama i zidovima centralnoevropskih i istoÄnoevropskih politiÄkih aktera koji se tiÄu izbegliÄke krize iz 2015. godine. Analiziram tri diskursa: konsekvencijalistiÄki, diskurs odgovornosti za pravednu raspodelu kosmopolitskih dužnosti i nacionalistiÄki diskurs. To poreÄenje treba da mi pomogne u preispitivanju primenjivosti argumenta Vendi Braun da države Äiji su suvereniteti na izmaku pokazuju simbole moÄi i snage izgradnjom zidova koji treba da odbrane njihov krhki ego sagraÄen oko nacionalnog ili religijskog identiteta. Najzad, želim da ocrtam politiÄke subjektivitete koji bivaju proizvedeni i legitimisani Äinovima fortifikacije unutar i izvan zazidanih zemalja Centralne i IstoÄne Evrope
Assessment of Liquefaction Potential Relevant to Choice of Type and Depth of Foundations in Seismically Active Areas
There is evidence of great increase of pore pressures in saturated sand soils during cyclic loading caused by earthquakes. These increased pore pressures can often increase to effective stresses in soil. Dependant on sand density, this can lead to a total loss of shear strength, liquefaction or greater deformability of soil. Emergence of liquefaction or great deformations within soil can cause significant damage or total destruction of constructions on the ground, even when they have been correctly designed. For this reason, it is very important to perform detailed geotechnical and seismic investigations of ground conditions and evaluate liquefaction potential for saturated sand soil in seismically active terrain. It is not possible to design stable constructions in certain types of terrain without the analyses of liquefaction potential. This paper refers to the comparative cost-analyses of two possible ways of the foundations of the business complex: shallow foundations with stabilization of potentially liquefiable sand deposit using vertical gravel drains versus deep pile foundation on unliquefiable soil
Bryophyte flora of the Uvac river gorge (Southwest Serbia)
In the examined area, 165 taxa were found and identified: 139 taxa from the class Bryopsida and 26 taxa from the class Marchantiopsida. Nine species are red-listed in Serbia. Material was collected from 62 localities, which were analyzed for similarity of chorological and ecological features using the Jaccard similarity index. Analysis of floristic elements and phytogeographic distribution showed that the greatest number of taxa are temperate elements with Holarctic distribution. Results of ecological analysis showed that in regard to the substratum aspect, terricolous, basophilous, and indifferent species were dominant. In relation to the ecological parameter humidity, most species were mesophilous. The majority of identified bryophytes were sciophilous taxa.
Endokrini i metaboliÄki profil junica holÅ”tajna i crvenog holÅ”tajna u peripartalnom periodu
The aim of this stady was to examine the relationship between triiodothyronine (T3), thyroxin (T4), insulin-like growth factor-I (IGF-I) and blood serum liver function biomarkers concentrations in Holstein and Red Holstein heifers during the peripartal period. In the first experimental group (I) were heifers of Holstein Friesian breed (n=10), and in the second experimental group (II) were Red Holstein heifers (n=10). Blood samples were taken from the vena coccygea three times during the short peripartal period (5 days before delivery, at delivery and 5 days after delivery), and blood serum samples were separated after spontaneous coagulation. Blood serum T3, T4 and IGF-I concentrations were determinated using radioimmunoassay (RIA). Blood serum concentrations of glucose (G), total protein (TP), albumin, (Alb), urea, total bilirubin (tBil) and aspartate aminotrasferase (AST) were determined using commercial ELISA kits. The statistical significance between means was determined using Student t-test. Blood serum T3 concentration in Group II was significantly lower after delivery, and T4 concentration was significantly higher before delivery (p lt 0.05), compared to Group I. Mean blood serum IGF-I concentrations between the two experimental groups were not significantly different at all time intervals. Relationships between the determined hormones showed a median positive correlation between T3, and T4 (r=0.74) in Group I and highly positive correlation in Group II (r=0.81). Blood serum thyroid gland hormones and IGF-I concentrations in healthy heifers during peripartal period vary considerably, the lowest values being determined immediately after calving in both experimental groups. Blood serum G, TP, Alb and urea concentrations were significantly higher in Group I at all investigated time intervals. Blood serum tBil concentration was significantly higher after partus in Group I (11.02 Ā± 3.33 : 8.49 Ā± 3.35 Ī¼mol/L, Group I vs. II, respectively), and AST activity was not significantly different at all intervals.Cilj ovih istraživanja je bio odreÄivanje koncentracije triijodtironina (T3), tiroksina (T4), insulinu sliÄnog faktora rasta-I (IGF-I) i biomarkera, pokazatelja funkcionalnog stanja jetre u krvnom serumu dva varijeteta junica HolÅ”tajn rase u peripartalnom periodu. Prvu eksperimentalnu grupu (I) Äinile su junice crno belog holÅ”tajna (n=10), a drugu grupu (II) junice crvenog holÅ”tajna (n=10). Krv za analize je uzimana iz repne vene, tri puta u peripartalnom periodu (5 dana pre partusa, na dan partusa i do 5 dana posle partusa), a krvni serum je odvajan nakon spontane koagulacije. U krvnom serumu je radioimunoloÅ”kom metodom (RIA, INEPZemun) odreÄivanja koncentracija trijodtironina (T3), tiroksina (T4) i insulinu sliÄnog faktora rasta-I (IGF-I). Koncentracija glukoze (G), ukupnih proteina (TP), albumina, (Alb), ureje, ukupnog bilirubina (tBil) i aktivnost aspartat aminotrasferaze (AST) je odreÄivana upotrebom komercijalnih ELISA kitova. StatistiÄka znaÄajnost razlika srednjih vrednosti ispitivanih endokrinih i metaboliÄkih parametara je odreÄena Studentovim t-testom. Dobijeni rezultati ukazuju na vrlo razliÄite koncentracije hormona Å”titne žlezde u krvnom serumu junica oba varijeteta holÅ”tajna pre i posle partusa. Koncentracija T3 je bila statistiÄki znaÄajno niža u grupi II nakon partusa, a T4 znaÄajno viÅ”a pre partusa (p lt 0.05) u odnosu na nivo hormona u grupi I. Za proseÄne vrednosti koncentracija IGF-I, izmeÄu isptivanih grupa nije ustanovljena statistiÄki znaÄajna razlike ni u jednom od tri perioda ispitivanja. UtvrÄena je srednje pozitivna korelacija izmeÄu koncentracije T3 i T4 (r=0,74) u krvnom serumu junica grupe I, i vrlo visoka pozitivna korelacija u grupi II (r=0,81). Koncentracija TP, Alb i ureje bila je statistiÄki znaÄajno viÅ”a kod junica grupe I u sva tri perioda ispitivanja. Nivo tBil u krvnom serumu je takoÄe bio poviÅ”en kod junica grupe I u sva tri perioda ispitivanja, ali su statistiÄki znaÄajne razlike izmeÄu srednjih vrednosti ustanovljene samo u periodu nakon partusa. Aktivnost AST u krvnom serumu junica oba varijeteta znaÄajno je varirala u svim periodima ispitivanja i nisu ustanovljene statistiÄki znaÄajne razlike izmeÄu srednjih vrednosti
Benefits of inoculation with azotobacter in the growth and production of tomato and peppers
The aim of this research was to investigate the effects of Azotobacter chroococcum in tomato and pepper growth and production by using two types of inoculation - seed inoculation and seedling inoculation. The effect of inoculation was observed thirty days after sowing, thirty days after transplanting, and in the phase of technological maturity. The following were measured: height of the plants, dry matter of the plants and number and the weight of the fruits. Inoculation had a positive effect on these in both plants. With tomato, better results were achieved when seedlings were inoculated. With pepper, the length of the plant and the dry matter were greater with seedling inoculation, whereas the number and the weight of the fruits were greater with seed inoculation
Aurivillius BaBi4Ti4O15 based compounds: Structure, synthesis and properties
The discovery of some Aurivillius materials with high Curie temperature or fatigue-free character suggests possible applications in high temperature piezoelectric devices or non-volatile ferroelectric random access memories. Furthermore, increasing concerns for environmental issues have promoted the study of new lead-free piezoelectric materials. Barium bismuth titanate (BaBi4Ti4O15), an Aurivillius compound, is promising candidate to replace lead-based materials, both as lead-free ferroelectric and high temperature piezoelectric. In this review paper, we report a detailed overview of crystal structure, different synthesis methods and characteristic properties of barium bismuth titanate ferroelectric materials
