Rađanje van braka u Srbiji: nedovoljno istražen fenomen / Nonmarital Fertility in Serbia: An Under-Researched Phenomenon
U Srbiji je, kao i širom Evrope, u poslednjih nekoliko decenija prisutan trend porasta vanbračnog fertiliteta. U 2017. godini je van braka rođeno 26% dece. U radu se sagledavaju osnovne karakteristike vanbračnog rađanja, na osnovu zvaničnih statističkih podataka i rezultata kvalitativnog istraživanja autora. O tome koliko se vanbračnih rađanja odvija u okviru vanbračnih zajednica a koliko među samohranim majkama, usled nedostatka statističkih podataka, zaključuje se indirektno. Rezultati analize ukazuju na nepovoljan socioekonomski položaj mnogih majki i dece rođene van braka. Stoga se ukazuje na potrebu institucionalnih mera podrške jednoroditeljskim porodicama. Takođe, naglašava se potreba produbljivanja znanja i povećanje obuhvata i kvaliteta podataka vezanih za fenomen vanbračnih rađanja
Metodički model poučavanja pjesama po sluhu i učinci njegova utjecaja na razvoj učeničkih glasovnih sposobnosti
The purpose of this paper was to verify the studied phenomenon (application of the
vocal warm up exercises model, as well as the designed and planned methodical
approach to learning songs by ear) by using an experiment with parallel groups. The
subject of this study was to determine whether it was possible to influence the quality
of singing and develop the vocal skills of younger school age students by implementing
a planned and directed methodical approach to learning songs by ear. In order to check
the effects of the implementation of the methodical model, the SAVS instrument (Scale
for the Assessment of Vocal Skills, Jeremić, 2011, p. 281) was used, subtests I, II, III, IV
and V (with equivalent forms for the initial and final assessment). In the comparison
of groups in relation to vocal skills, a general linear model was used, and in particular
a multivariate analysis of covariance with repeated measures (MANCOVA with
repeated measures). The sample of this research consisted of second grade students of
elementary schools in Sombor and Kikinda, Serbia. The tests of within subject effects
showed that the two groups differed in their level of vocal skills, when the average of
the two measurements was observed F (1) =11.424, p=.001.Svrha je ovoga rada provjeriti istraživani fenomen (primjena modela vježbi
vokalnog zagrijavanja, kao i osmišljen i planski metodički pristup učenju pjesme
po sluhu) eksperimentom s paralelnim skupinama. Predmet je ovog istraživanja
utvrditi je li moguće utjecati na kvalitetu pjevanja i razvijati glasovne sposobnosti
učenika mlađeg uzrasta planiranim i usmjerenim metodičkim pristupom za
učenje pjesama po sluhu. Kako bi se provjerili učinci provedbe metodičkog modela,
korišten je SPVS instrument (Skala provjere vokalnih sposobnosti, Jeremić, 2011:
281), subtest I, II, III, IV i V (ekvivalentni oblik početnog i završnog testiranja).
Za usporedbu skupina po glasovnim sposobnostima korišten je opći linearni
model, a osobito multivarijacijska analiza kovarijanata s ponovljenim mjerenjima
(MANCOVA s ponovljenim mjerenjima). Uzorak ovog istraživanja činili su učenici
drugog razreda osnovnih škola u Somboru i Kikindi, u Srbiji. Testovi učinaka
unutar ispitanika pokazuju da se dvije skupine razlikuju po razini vokalnih
sposobnosti pri promatranju prosjeka dvaju mjerenja F (1) = 11.424, p = .001

Češka politika prema porodici
U radu se predstavlja razvoj i transformacija češke populacione politike od 1950-ih godina. Ona se menjala od pronatalitetne, sprovođene u vreme kada je Češka bila deo komunističke Čehoslovačke, preko, uglavnom socijalne, u vreme tranzicije iz 1990-ih, do aktualizacije i uvođenja novih mera u poslednjoj deceniji. Mere koje su se definisale i sprovodile u određenom vremenskom razdoblju predstavljale su odgovor države na porodično i reproduktivno ponašanje stanovništva, koje se najčešće ogledalo u niskom fertilitetu, u velikoj meri uslovljeno tada aktuelnim društvenim, ekonomskim i kulturnim uslovima. U tom smislu, period najvećih izazova nastupio je posle 1989. godine, sa promenom društveno političkog sistema i velikim ekonomskim i socijalnim promenama koje su usledile, kao i opadanjem fertiliteta na ekstremno nizak nivo. Tadašnja politika prema porodici isključila je pronatalitetne podsticaje i olakšice i zadržala samo socijalne mere namenjene smanjenju siromaštva i ublažavanju nejednakosti. Od ranih 2000-ih, definišu se i sprovode nove mere, podstaknute potrebom da se zaustavi i promeni trend pada fertiliteta koji je dostigao najniži nivo (SUF 1,13 u 1999), sagledavanjem mogućih negativnih socioekonomskih posledica, ali i preporukama i direktivama Evropske unije, čiji je član Češka Republika postala 2004. godine. Počev od 2000. zaustavljeno je opadanje fertiliteta, SUF je do 2011. dostigao 1,43, a prema podacima za 2016. iznosio je 1,63 deteta po ženi
Language, gender, and sexual orientation: Gender-specific features of discursive styles of homosexual users of an internet forum
Ovo istraživanje nastoji da utvrdi da li se, i na koji način, homoseksualne osobe prilikom komunikacije u internet okruženju oslanjaju na stilske odlike koje su karakteristične za određeni rod. Polazi se od pretpostavke da u osnovi razlika u jezičkoj praksi ne stoje određene, bilo rodne bilo seksualne, identitetske kategorije koje bi u tim praksama imale samo sredstvo svog izražavanja, već se na jezik gleda kao na jedan od resursa koji omogućava da se odgovori na različite zahteve komunikacione situacije. Metodološki okvir za prikupljanje i analizu uzoraka verbalne interakcije je analiza sadržaja (računate su relativne frekvence lingvističkih odrednica koje su međusobno poređene upotrebom statističkih tehnika), a na ovaj način dobijeni rezultati dopunjeni su kvalitativnom analizom toka komunikacije kojom se podrobnije ispituje posredovanje konteksta konverzacije prilikom izbora rodno specifičnih diskurzivnih odlika. Nalazi ukazuju na to da se homoseksualni muškarci i žene razlikuju s obzirom na ispoljavanje rodno obojenog diskurzivnog stila. U diskusiji se navode argumenti u prilog tome da se ove razlike interpretiraju s obzirom na osobenost diskusionog okruženja i postojanje određenih normi koje modeliraju interakciju među učesnicima u diskusiji.This study seeks to determine whether and in which way homosexual people rely on gender-specific style characteristics when communicating in the internet environment. It is assumed that the basis of differences in language practices is not some identity category (either gender or sexual), that uses these practices only as a means of expression. Instead, language is seen as a resource that allows us to respond to a variety of communication situations. The methodological framework for collecting and analyzing the samples of verbal interaction is content analysis (relative frequencies of linguistic parameters are first calculated and then compared by using statistical techniques), and the results are then supplemented with a qualitative analysis of communication flow which further examines the mediating effect of conversational context in the selection of gender-related discursive features. The findings suggest that homosexual men and women differ when it comes to the expression of gender-specific discursive style. In conclusion, I argue in favor of the interpretation of these differences with respect to the specificity of the communication context and existence of certain norms that model the interaction among the participants in the discussion
Woman as a subject of childbirth: Physical, technological and institutional aspects
Porođaj predstavlja specifičnu tačku susreta prirode i kulture: to je biološki događaj u kome su glavni akteri društvena bića, prirodni proces kome je kroz naučno-tehnološko prevođenje dat poseban kulturni status. Ova kompleksna priroda porođaja postavlja dvostruki izazov pred ženu koja se porađa. Sa jedne strane, tok dramatičnih telesnih promena koji je u najvećoj meri izvan njene kontrole predstavlja pretnju za njenu otelovljenu subjektivnost. Sa druge strane, to što je u savremenom društvu porođaj postao objekat medicinskih znanja, praksi i tehnika po pravilu podrazumeva njegovo redukovanje na medicinski vođen fiziološki proces koji se ne oslanja na subjektivnu uključenost žene u bilo kom relevantnom smislu. Postavlja se pitanje da li uopšte žena uspeva da bude subjekt ovog procesa koji joj se dešava i koji je pre svega tehnološki posredovan i spoljašnje regulisan? Iskustvo porođaja posmatraću kao kompleksan proces koji je određen interakcijom između konstantno promenljivog otelovljenog iskustva i medicinskih praksi i tehnika kojima je žena podvrgnuta. Na osnovu analize porođajnih narativa pokušaću da pratim tok ovog iskustva i brojne promene kroz koje žena kao subjekt prolazi u u lokalnom akušerskom kontekstu koji sa sobom nosi niz institucionalnih specifičnosti.Childbirth represents a specific meeting point between nature and culture: it is a biological event in which the main actors are social beings, a natural process which has been given a special cultural status through the process of scientific-technological translation. The complex nature of childbirth also raises twofold challenge to woman in labour. On the one hand, the flow of dramatic bodily changes that is mostly beyond her control represents a threat to her embodied subjectivity. On the other hand, the fact that labour is turned into an object of medical knowledge, practices and techniques in contemporary society usually implies its reduction to medically guided physiological process that does not rely on women's subjective involvement in any relevant way. This brings up the question of whether a woman manages to be the subject of a process that is happening to her and that is primarily technologically mediated and externally regulated? I will think of the birth experience as a complex process which relies on the interaction between the constantly changing embodied experience and medical knowledge and techniques that woman is subjected to. Based on the analysis of the birth narratives, I'll try to follow the flow of this experience and numerous changes that women as subject is going through in local obstetrical context which bears a number of institutional specificities
Wykorzystanie złożonego indeksu zielonej gospodarki EEPSE do oceny postępu gospodarek rozwijających się w osiąganiu Celów zrównoważonego rozwoju
As a concept, the green economy refers to the transition from coal to renewable energy sources to reduce pollution, the energy efficiency of production processes to achieve savings, the reuse of materials from waste in business and energy production, changes designed to stop harmful climate change and bring new opportunities for economic development. In this way, conflicts between economic development and environmental issues are resolved, with the aim of achieving sustainability of the economy and society. The aim of the study is to provide a comparative analysis of the level of development of the green economy in selected 20 emerging economies and their progress towards achieving the Sustainable Development Goals (SDGs) from the 2030 Agenda using the EEPSE Green Economy Index (EEPSE GEI), based on Quintuple Helix Innovation Model (QHIM), and examine the interdependence between each of the 5 subsystems (quality of education system, economic aspects, political system, civil society, and natural environment) with this index. The results indicate that among the group of countries observed, Estonia is the best performer, while Egypt has the lowest performance. The results, also, indicate the important role of each of the subsystems in EEPSE GEI. The study can be useful for policy makers to identify weaknesses in achieving the SDGs.Jako koncepcja, zielona gospodarka odnosi się do przejścia z węgla na odnawialne źródła energii w celu ograniczenia zanieczyszczeń, efektywności energetycznej procesów produkcyjnych w celu osiągnięcia oszczędności, ponownego wykorzystania materiałów z odpadów w biznesie i produkcji energii, zmian mających na celu zatrzymać szkodliwe zmiany klimatyczne i stworzyć nowe możliwości rozwoju gospodarczego. W ten sposób rozwiązywane są konflikty pomiędzy rozwojem gospodarczym a kwestiami środowiskowymi, umożliwiając osiągnięcie zrównoważonego rozwoju gospodarki i społeczeństwa. Celem artykułu jest dokonanie analizy porównawczej poziomu rozwoju zielonej gospodarki w wybranych 20 gospodarkach rozwijających się oraz ich postępu w realizacji Celów zrównoważonego rozwoju (SDGs) wynikających z Agendy 2030 z wykorzystaniem Indeksu Zielonej Gospodarki EEPSE (EEPSE GEI), w oparciu o Model Innowacji Pięciokrotnej Helisy (QHIM) i bada współzależność pomiędzy każdym z 5 podsystemów (jakość systemu edukacji, aspekty ekonomiczne, system polityczny, społeczeństwo obywatelskie i środowisko naturalne) za pomocą tego indeksu. Wyniki wskazują, że wśród obserwowanej grupy krajów najlepiej radzi sobie Estonia, a najgorzej Egipt. Wyniki wskazują także na ważną rolę każdego z podsystemów w EEPSE GEI. Badanie może być przydatne dla decydentów w celu zidentyfikowania słabych punktów w osiąganiu Celów zrównoważonego rozwoju
Molecular markers of chronic inflammation and apoptosis in inflammatory bowel diseases
Hronične inflamatorne bolesti creva (HIBC) predstavljaju rastući globalni zdravstveni
problem, posebno u belim populacijama, uključujući i srpsku populaciju. Ova studija
obuhvatila je dva tipa HIBC - inflamatornu bolest creva (IBC), koju čine Kronova bolest
(KB) i ulcerozni kolitis (UK); i celijačnu bolest (CB). HIBC su kompleksne bolesti u čijoj,
još uvek potpuno nerazjašnjenoj etiologiji učestvuju genetički, sredinski i imunološki faktori.
Razvoj IBC je rezultat poremećenog imunološkog odgovora na crevnu mikrofloru kod
genetički podložnih osoba. Ustanovljen je veliki broj asocijacija između IBC i varijanti u
genima čiji proteinski produkti učestvuju u nespecifičnom imunskom odgovoru. Oštećenje
intestinalne mukoze kod pacijenata sa IBC dešava se kao posledica deregulacije
inflamatornih i apoptotskih procesa koji utiču na dugovečnost T ćelija i integritet epitelijalne
barijere. Protein NF-κB je jedan od ključnih regulatora transkripcije gena eksprimiranih
tokom ovih patogenetskih promena. U mukozi pacijenata sa KB dolazi do formiranja
granuloma, limfoidnih mikrostruktura karakterističnih i za druge inflamatorne bolesti, među
kojima je reumatoidni artritis (RA). Zbog toga su KB i RA klasifikovane kao granulomatozne
bolesti. U poređenju sa brojnim, još uvek nedovoljno definisanim genetičkim faktorima
rizika za razvoj IBC, nasledna komponenta u razvoju CB je dobro okarakterisana i najviše je
povezana sa specifičnim varijantama gena HLA-DQ.
Jedan od ciljeva ove studije je bio da ispita asocijaciju između HIBC i određenih genetičkih
varijanti. Tačnije, analizirana je povezanost IBC sa varijantama u genima NOD2, TLR4,
TNF-α, IL-6, IL-1β i IL-1RN, i ispitan je njihov prediktivni značaj za pojavu IBC. Varijanta
u genu IL-6 ispitana je kao faktor rizika za nastanak dve granulomatozne bolesti, KB i RA.
Takođe, analizirana je distribucija genotipova HLA-DQ u grupi pedijatrijskih pacijenata
obolelih od CB i procenjen je rizik za pojavu CB koju ovi genotipovi nose. Sledeći cilj je bila
analiza nivoa transkripcije proinflamatornih gena IL-6 i TNF-α, i apoptotskih gena Bcl-2,
Bax, Fas i FasL u intestinalnoj mukozi i perifernoj krvi pacijenata obolelih od KB, kako bi
se definisali ekspresioni profili gena uključenih u patogenezu KB i ispitao njihov
dijagnostički potencijal. Poslednji cilj u okviru istaživanja vezanog za IBC odnosio se na
analizu DNK vezujuće aktivnosti NF-κB iz jedarnih ekstrakata intestinalne mukoze
pacijenata obolelih od KB...Chronic inflammatory bowel diseases (CIBDs) remain an expanding global health problem,
particularly in most Caucasian populations, including Serbian. The focus of this study
included two types of chronic inflammatory bowel diseases - inflammatory bowel disease
(IBD), which comprises Crohn’s disease (CrD) and ulcerative colitis (UC); and celiac disease
(CD). These are complex diseases with various genetic, environmental and immunological
risk factors, whose etiologies are not yet fully resolved.
The development of IBD is a result of abnormal immune response that occurs in genetically
susceptible individuals against the enteric flora. Many studies have investigated associations
between IBD occurrence and variants in genes that encode proteins involved in nonspecific
immune response. Intestinal mucosal damage in CrD patients occurs as a result of the
deregulation of inflammatory and apoptotic processes, which influence T cell longevity and
epithelial barrier integrity. Regulatory protein NF-κB has a key role in the transcription of
genes whose products are involved in these pathogenic events. Another property of CrD is
formation of granulomas, which can also occur in other diseases, such as rheumatoid arthritis
(RA). For that reason, CrD and RA are categorized as granulomatous diseases. Compared
with numerous, still insufficiently defined genetic risk factors for the development of IBD, a
genetic component in CD development is well characterized and mostly associated with
specific variants of HLA-DQ genes.
One of the aims of this study was to evaluate disease-gene associations. More precisely, we
examined IBD associations with several genetic variants - variants in NOD2, TLR4, TNF-α,
IL-6, IL-1β and IL-1RN genes, and investigated their contribution in the prediction of IBD
occurrence. Additionally, we analyzed variant in IL-6 gene as a risk factor for two types of
granulomatous diseases, CrD and RA. Also, we inspected the distribution of HLA-DQ
genotypes in the group of pediatric celiac patients and estimated the risk of CD development
that these genotypes confer. Another aim was the analysis of mRNA level of proinflammatory
IL-6 and TNF-α, and apoptotic Bcl-2, Bax, Fas and FasL genes in intestinal
mucosa, as well as in the peripheral blood of CrD patients, in order to reveal the expression
patterns involved in the pathogenesis of CrD..
Distributed subjectivity in pregnancy: self, body and medical technology
Rezime
Predmet empirijske i teorijske analize u ovoj tezi predstavlja oblikovanje i promena
subjektivnosti žena tokom trudnoće i porođaja, posebno s obzirom na dramatične telesne
promene koje se tada odvijaju i s obzirom na način na koji medicinska znanja, prakse i
tehnike posreduju ovaj proces. Cilj istraživanja bio je da se kroz analizu trudničkih i
porođajnih narativa rekonstruišu transformacije doživljajne subjektivnosti žene tokom
trudnoće i porođaja u lokalnom kontekstu koji sa sobom nosi niz, pre svega
institucionalnih, specifičnosti.
Teza je započeta izlaganjem i kritičkim preispitivanjem reprezentacija i praksi koje
su povezane sa tretiranjem trudnoće i porođaja u savremenom društvu, kao i
rekonstrukcijom njihove istorijske geneze. Savremena situacija može se videti kao
kulminacija istorijskog procesa stavljanja ženskog reproduktivnog zdravlja pod nadležnost
medicine koje je započelo u moderni. Između ostalog, ovaj proces podrazumeva to da su
trudnoća i porođaj posmatrani kao potencijalno rizični i patološki, pa su zbog toga tretirani
od strane medicinskih stručnjaka uz oslanjanje na brojna tehnološka sredstva, i to u
institucionalnom okruženju. To svakako nosi određene posledice po doživljajnog subjekta i
ove posledice su u drugom, empirijskom, delu teze detaljno ispitane.
Na kraju uvodnog dela rad je pozicioniran unutar aktuelnih debata oko
reproduktivnih pitanja. Specifičan vid ovog pozicioniranja, omogućen je oslanjanjem na
jednu drugačiju teoriju kako subjekta, tako i tehnologije, koji se više ne posmatraju kao
neke date, koherentne i dobro individuirane celine, već kao kompleksne konstelacije koje
su lokalno situirane i koje se mogu samo empirijski opisati. Oslanjanje na ovu promenjenu
perspektivu koja potiče iz studija nauke i tehnologije i savremenog feminizma, odnosno pre
svega na teoriju aktera-mreže (ANT) kao njeno konceptualno-metodološko jezgro, u radu je
omogućilo stavljanje akcenta na materijalne aspekte društvenog okruženja i
institucionalno-tehnološku praksu.
I pored svog potencijala ovog savremenog shvatanja, njemu nedostaju određeni
resursi specifično podešeni za analizu subjektivnosti, kojoj s e u o vom r adu p rilazi i z
perspektive prvog lica, kao i njene telesne situiranosti. Zbog toga je uveden dodatni
fenomenološki teorijski okvir koji omogućava diferenciranu konceptualnu rekonstrukciju
otelovljenog iskustva subjekta. Pored toga, u ovom teorijskom delu rada izvršeno je i
dodatno teorijsko situiranje unutar psihologije, kroz razmatranje dve relevantne oblasti
koje se ovom temom bave – psihologije žena i zdravstvene psihologije.
Metodološko poglavlje sadrži refleksivni narativ same autorke o izvedenom
empirijskom istraživanju. Osim detaljnog obrazlaganja svih relevantnih metodoloških
odluka, u njemu se preispituje uloga istraživača u svim aspektima istraživanja – od izbora
fenomena i formulisanja pitanja, do realizacije istraživanja. Osnovni empirijski materijal na
kome je zasnovana kvalitativna analiza čini dvadeset pet polustrukturisanih intervjua,
prosečnog trajanja od po dva sata, obavljenih sa trinaest sagovornica – prvi pri kraju
trudnoće, a drugi nakon porođaja. Podaci o lokalnom institucionalnom okruženju i
medicinskim praksama i tehnikama dopunjeni su sekundarnim materijalom: beleškama sa
terenskog istraživanja koje je obavljeno u jednom beogradskom porodilištu, informacijama
dobijenim iz razgovora sa malobrojnim lekarima koji su pristali na intervju i analizom
medicinskih udžbenika. Osnovni metodološki okvir za tumačenje trudničkih i porođajnih
narativa predstavljala je interpretativna fenomenološka analiza koja za cilj ima detaljnu
rekonstrukciju individualnog iskustva, ali i njegovo situiranje kako u socio-kulturnom, tako
i u teorijskom kontekstu.
Druga polovina teze posvećena je izlaganju i komentarisanju empirijskih nalaza. Ona
je podeljena u dve veće celine – u prvoj detaljno je analizirano iskustvo trudnoće, a u drugoj
iskustvo porođaja, uz navođenje relevantnih citata učesnica u istraživanju. Kroz diskusiju
konkretnih iskustava pokazano je to da su posebno na početku trudnoće, ali i tokom nje,
telesni doživljaji nejasni i višesmisleni i da se žene, po pravilu oslanjajaju na različite
medijatore – medicinska znanja, tehnološka sredstva (kao što su hormonski test ili
ultrazvuk), kao i na iskustva drugih osoba – u pokušaju da ispravno protumače, odnosno
diskurzivno obrade svoje stanje, i da se praktično odnose prema njemu, odnosno da
planiraju i izvode aktivnosti i organizuju svoje ponašanje.
Veoma često medicinske tehnike imaju značajnu ulogu u razrešenju neizvesnost i
omogućavaju ženi i potrebno znanje i priliku da informisano bira svoje postupke, ali one
ponekad vode i indukovanju ili produbljujivanju neizvesnosti. Dakle, tehnologija ima
različite uloge tokom trudnoće i porođaja i vodi različitim ishodima za žene kao otelovljene
subjekte. Postoje najmanje dva značajna faktora kojima je to određeno – odnos prema
telesnom iskustvu i organizacija prakse u kojoj se tehnologija pojavljuje tj. konkretni način
na koji je tehnologija institucionalno situirana. Oba aspekta detaljno su ispitana tokom
analize narativa.
Značajan aspekt iskustva trudnoće, koji postavlja specifičan izazov pred
subjektivnost žene, predstavlja činjenica da u njenom telu raste drugo biće koje vremenom
postaje sve diferenciranije i autonomnije. Beba za trudnu ženu dobija sve određenije obrise
i počinje da se doživljava kao nezavisno biće. I medicinska znanja/tehnologija i otelovljeno
iskustvo žene igraju značajnu ulogu u individuiranju bebe i kroz analizu praćena je
dinamika relativnog doprinosa i proces interakcije ova dva modaliteta iskustva. I nezavisno
od ovog specifičnog aspekta otelovljenog iskustva koji se tiče prisustva bebe, ženino telo
prolazi kroz velike i mnogobrojne transformacije tokom relativno kratkog perioda od
nekoliko meseci. Analizirano je kako žena doživljava ove promene i kako se na njih
prilagođava tokom svakodnevnog funkcionisanja.
Znanja i veštine koje je tokom meseci trudnoće stekla i odnos prema sopstvenom
telu koji je izgradila omogućavaju ženi izvesna pozicioniranja i definišu njene potrebe i
preferencije na samom porođaju. Ipak, stvarni ishodi u velikoj meri zavise od materijalnih i
simboličkih karakteristika institucionalnog okruženja u kome se porođaj odvija, što je
detaljno analizirano u delu teze posvećenom razmatranju porođajnih iskustava. Ukazano je
na to kako konkretna konstelacija medicinske prakse, implicitne i eksplicitne norme,
obrasci odnošenja, ali i materijalne karakteristike institucionalnog okruženja presudno
određuju to kako će žena doživeti porođaj i svoju ulogu u njemu.
Žena je tokom porođaja suočena sa donekle netransparentnim nizom povremeno
dramatičnih telesnih događaja koje ne može sasvim dobro da anticipira i da kontroliše, što
samo po sebi predstavlja izazov za njenu otelovljenu subjektivnost. Činjenica da nema
kontrolu, a često ni uvid, u tok medicinskih intervencija kome je podvrgnuta, ovu situaciju
dodatno komplikuje. Detaljno je analizirano to kako se žena odnosi prema nizu telesnih i
medicinskih događaja tokom porođaja, odnosno da li uspeva da prisvoji i bude akter tog
procesa koji joj se dešava. Empirijski deo teze završen je razmatranjem mogućnosti za
drugačije ishode po subjektivnost žene koji se, makar u izvesnoj meri, nalaze i u trenutnoj
lokalnoj konstelaciji porođaja, i pored svih njenih nesavršenosti i nedostataka.
S obzirom na to da su poglavlja u kojima su diskutovani nalazi istraživanja bila
fokusirana na različita konkretna pitanja i aspekte transformacije ženine subjektivnosti
tokom trudnoće i porođaja, u zaključnom poglavlju ocrtane su neke opštije tendencije i
ponovo razmatrana, ovaj put u svetlu empirijskih uvida, neka od pitanja koja su otvorena u
teorijskim delovima rada. U opštim terminima ispitane su različite uloge tehnologije i
njihov odnos prema otelovljenom iskustvu žene, koje tokom trudnoće i porođaja sa sobom
nosi niz specifičnosti. Ukazano je na to da individualni subjekt ne mora da bude redukovan
susretom sa tehnologijom, on kroz taj susret može tek da dobije specifične oblike iskustva i
prilike za agensnost. Na kraju, istaknuto je da analiza trudničkog i porođajnog iskustva,
koja ukazuje na distribuiranu, procesualnu i (tehnološki) posredovanu prirodu
subjektivnosti uopšte, može da nam posluži kao značajan resurs za zasnivanje jedne
adekvatnije psihološke teorije subjekta.Abstract
The subject of empirical and theoretical analysis in this thesis is the process of
shaping and transformation of women´s subjectivity during pregnancy and childbirth,
especially considering the dramatic bodily changes that occur and considering the way in
which medical knowledge, practices and techniques mediate this process. The aim of the
study was to reconstruct the transformations of experiential subjectivity of women during
pregnancy and childbirth, through analyzing pregnancy and birth narratives, in a local
context which possess a number of (primarily institutional) specificities.
The thesis begins by discussing and critically examining the representations and
practices associated with treating pregnancy and childbirth in contemporary society, as
well as reconstructing their historical origins. The contemporary situation can be seen as
the culmination of a historic process of putting women's reproductive health under the
jurisdiction of medicine that began in modern period. Among other things, this process
implies that pregnancy and childbirth were viewed as potentially risky and pathological,
and were therefore treated by medical professionals relying on numerous technological
means, in the institutional environment. This certainly entails certain consequences for the
experiential subject and these consequences are examined in detail in the second,
empirical, part of the thesis.
At the end of the introduction part, the thesis is positioned within the current
debate about reproductive issues. A specific aspect of this positioning was enabled by
relying on a different theory of both, the subject, and the technology, which are no longer
considered as given, coherent and well individualised wholes, but as complex
constellations that are locally situated and that can only be described empirically. Relying
on this altered perspective that comes from the study of science and technology and
modern feminism, or primarily on the actor-network theory (ANT) as its conceptualmethodological
core, permitted placing emphasis on the material aspects of the social
environment and institutional and technological practice.
Despite all the potential of this modern understanding, it lacks certain resources
specifically tuned for the analysis of subjectivity, which in this work is approached from the
first person perspective, as well as being bodily situated. Therefore an additional
phenomenological theoretical framework is introduced, that allows for differentiated
conceptual reconstruction of the embodied experience of the subject. Further, in this
theoretical part of the work, additional theoretical positioning of the thesis within
psychology was carried on, through considering two relevant areas that deal with this
subject - psychology of women and health psychology.
The methodology chapter contains a reflexive narrative, by the author herself, about
the performed empirical research. In addition to a detailed description of all relevant
methodological decisions, this chapter examines the role of the researcher in all aspects of
the research – from choosing the phenomenon and formulating questions, to performing
the research. The main empirical material on which the analysis is based consists of
twenty-five semi-structured interviews with thirteen interviewees, first at the end of
pregnancy, and second after childbirth. Data on the local institutional environment and
medical practices and techniques are complemented with secondary material: notes from
the field research that was conducted in one of the Belgrade maternity hospitals,
information obtained from interviews with the few doctors who agreed to an interview and
analysis of the medical textbooks. The basic framework for the interpretation of pregnancy
and birth narratives was the interpretative phenomenological analysis that aims to achieve
a detailed reconstruction of individual experience, but also to position it in both sociocultural,
as well as theoretical context.
The second half of the thesis is dedicated to the presentation and discussion of the
empirical findings. It is divided into two major parts - the experience of pregnancy is analyzed in
detail in the first part, and the experience of childbirth in the second, both including relevant
citations of the participants in the study. Through the discussion of specific experiences, it is
shown that (particularly at the beginning of pregnancy, but during it as well) bodily experiences
are vague and ambiguous and that women generally rely on different mediators – medical
knowledge, technological means (such as pregnancy test or ultrasound) as well as the
experiences of others – in an attempt to correctly interpret and discursively analyze their
condition, and to practically orient themselves towards it, or in other words, to plan and conduct
activities and organize their behavior.
Very often the medical techniques play an important role in resolving the uncertainty and
allow women both the knowledge and opportunity to choose their actions in an informed way,
but they sometimes lead to inducing or deepening that uncertainty. Thus, the technology has a
variety of roles during pregnancy and childbirth, and leads to different outcomes for women as
embodied subjects. There are at least two important factors that determine that – the relationship
with the bodily experience and organization of practice in which the technology occurs, that is
the specific manner it is institutionally situated. Both aspects are examined in detail during the
analysis of narratives.
An important aspect of the experience of pregnancy, which sets a specific challenge to
the subjectivity of women, is the fact that in her body grows another being that eventually
becomes increasingly differentiated and autonomous. For a pregnant woman, the baby gets
increasingly more specific and begins to be perceived as an independent being. Medical
knowledge/technology and woman’s embodied experience play significant roles in the
individuation of the baby and the dynamics of the relative contribution of these two modalities of
experience and the process of their interaction are followed through the analysis. Apart from this
specific aspect of embodied experience concerning the presence of the baby, a woman's body
undergoes significant and numerous transformations over a relatively short period of time. It was
analyzed how women experience these changes and how they adapt to them in their daily
functioning.
Knowledge and skills that a woman gained during pregnancy and the relationship she
established towards her own body, enable her certain positioning and define her needs and
preferences during childbirth. However, the actual outcomes largely depend on the material and
symbolic characteristics of the institutional environment in which the birth takes place, which is
analyzed in detail in the part of the thesis dedicated to the discussion of birth experiences. It was
pointed out that the specific constellation of medical practice, implicit and explicit norms,
relationship patterns, and material characteristics of the institutional environment crucially
determine how a woman will experience the birth and her role in it.
A woman during childbirth is faced with a somewhat non-transparent series of
occasionally dramatic bodily events that she cannot anticipate and control very well, which itself
is a challenge for her embodied subjectivity. The fact that she does not control, and often has no
insight into the course of medical interventions performed on her, makes this situation even more
complicated. How a woman relates to a series of both bodily and medical events during birth,
and whether she manages to appropriate and be an actor of the process that is happening to her,
is analyzed in detail. The empirical part of the thesis is completed by considering the possibilities
for different outcomes for women’s subjectivity which are present, at least to some extent, in the
current local constellation of the birth, in spite of all its imperfections and flaws.
The chapters in which the research findings were discussed focused on various specific
issues and aspects of the transformation of the woman's subjectivity during pregnancy and
childbirth. Therefore, in the concluding chapter, some more general tendencies are outlined and
some of the questions that were opened in the theoretical parts of the work were discussed again,
this time in the light of empirical insights. Different roles of technology and their relation to the
embodied experience of women (which has a number of specific features during pregnancy and
childbirth) were examined in general terms. It is pointed out that the individual subject does not
have to be reduced through encounters with the technology – she could even get specific forms
of experience and opportunities for agency through this encounter. At the end, it was suggested
that the analysis of pregnancy and birth experience, which indicates distributed, processual and
(technologically) mediated nature of subjectivity in general, can serve as an important resource
for the establishment of a more adequate psychological theory of the subject
Nanoscale metal oxides as materials used for modification of carbon-based electrodes in electrochemical sensors
Nanostructured metal oxides used as modifiers of various carbon-based working electrodes serve as the basis for designing sensitive electrochemical sensors to detect desired analytes. The sensors we develop are distinguished by low detection limit (LOD), high analyte selectivity, sensitivity, and versatile real-world sample use case. In this work we present the design of two based on metal oxides as modifiers of carbon paste working electrode (CPE) and their applications in the electrochemical determination of levodopa and adrenaline. The physicochemical properties of designed materials were analyzed by complementary experimental technics (XRPD, TEM, SEM, EDS, electrochemical measurements) to determine their (micro)structural properties and correlate them with electroanalytical performance. Europium has been considered a significant lanthanide element with higher redox reaction behavior. We conducted a hydrothermal synthesis of Eu2O3@Cr2O3 and used them for CPE modification. The proposed Eu2O3@Cr2O3/CPE electrode was used to develop an analytical procedure quantifying L-Dopa in a wide micromolar linear range (1-100 µM), high sensitivity of 1.38 µA µM−1 cm−2 and a low detection limit (LOD = 0.72 µM). On the other side, we investigated the physicochemical properties of the gallium/bismuth mixed oxides and studied the influence of different Ga2O3:Bi2O3 ratios on the electrochemical detection of adrenaline. Square wave voltammetry was optimized, and the best electrode showed a wide linear working range of 7-100 μM, under optimized conditions. The LOD for the proposed sensor was calculated to be 1.9 μM, with a low limit of quantification (LOQ = 5.8 μM). The total performance of the sensors, particularly their performance on real-world samples and their potential for commercialization, had to be carefully evaluated during the sensor construction. Our team is devoted to developing highly selective electrochemical sensors based on nanomaterials to be potentially used as the basis for the fabrication of high-performance miniature devices with exceptional sensitivity to specific analytes, like adrenaline and L-Dopa, in this research
