Marković, Dejan D.
- Abstract
Esej razotkriva heterogenu globalnu situaciju kasnih 1960-ih i ranih 1970-ih, periodu globalnih društvenih nemira i promena, u kojemu su se stvarnost i film češće nego što je to obično slučaj prelivali jedno u drugo. Godina 1968. predstavljala je preokret. Tet ofanziva u Vijetnamu; praško proleće; Demokratska konvencija u Chicagu, suzavac i pendreci; Mexico City, masakr preko stotinu demonstranata pred Olimpijske igre; vrhunac angažmana SAD-a u Vijetnamu... Sami filmovi s naglaskom na dokumentarne predstavljali su deo mnogo većeg projekta. Oni su bili oruđe, korišćeno u sveobuhvatnom kontekstu. Bili su “sredstva, centralna tačka oko koje se razvijao javni diskurs i mobilizovanje ljudi na akciju.” Kao što je to filmski kolektiv Newsreel New York poručio u svom prvom javnom saopštenju, decembra 1967: “Za većinu nas filmsko stvaralaštvo je nerazdvojno od društvene aktivnosti u ovom ili onom obliku.” Radilo se zapravo o kreativnom sjedinjavanju kulturne i političke aktivnosti. Kao i o tome “kako upotrebiti takve filmove za uvećavanje i aktiviranje društvene i političke svesti.” Istina o sada već davnim istorijskim događajima koju su autori ovih filmova herojski i posvećeno snimali, dijametralno se razlikovala od onoga što su ljudi širom sveta mogli da vide na večernjim TV vestima ili da saznaju čitajući izveštaje iz štampe.

- Abstract
U ovoj disertaciji predmet istraživanja je rešavanje problema optimizacije resursa javnog poštanskog operatora (JPO). Predložen je model koji optimizuje ograničene resurse, troškove i operativne prihode korišćenjem neparametarske analize, DEA (engl. Data Envelopment Analysis). Testiranje i verifikacija predloženog modela izvršeni su na skupu od 27 JPO iz zemalja Evropske Unije i Srbije. Dobijeni rezultati eksplicitno pokazuju da su postojeći resursi i način kako se oni koriste ključni u postizanju rezultata rada, kao i to kako može da bude definisan efikasan operativni plan. Između ostalog, za slučaj javnog poštanskog operatora u Srbiji, rezultati ukazuju da ne postoji višak u broju zaposlenih, dok je višak prepoznat u ukupnom broju jedinica poštanske mreže. Pored toga, predstavljeno je izvođenje analize evaluacije efikasnosti javnog poštanskog operatora tokom vremena. U disertaciji, predložen je originalni višeulazni i višeizlazni model za merenje troškovne efikasnosti, CE (engl. Cost Efficiency) dostavnih jedinica poštanske mreže. Analizirana je dostavna mreža javnog poštanskog operatora u Srbiji koja uključuje 1,194 dostavne jedinice. Problem brojnosti i heterogenosti ovih jedinica prevaziđen je definisanjem originalnog algoritma za klasterovanje. Ovaj algoritam je obezbedio poređenje efikasnosti uporedivih jedinica, kao i troetapnu analizu: jedinice-klasterimreža. Dobijeni nalaz ukazuje da je posmatrana dostavna mreža troškovno neefikasna (CE=40%). Dalje, dekompozicijom CE objašnjeno je kako nivo troškovne efikasnosti može biti poboljšan. Ilustracije radi, utvrđeno je da najmanje 794 dostavne jedinice imaju mogućnost za poboljšanje samo na osnovu realokacije resursa. Istražen je uticaj ekonomije obima na efikasnost dostavnih jedinica gde je utvrđeno da ona ima jači uticaj na efikanost malih jedinica u poređenju sa velikim jedinicama. Konačno, na osnovu izvedenih rezultata, dato je obrazloženje zašto predloženi model za merenje troškovne efikasnosti može da bude, In this dissertation the research subject was to solve the problem of resource optimization of Universal Service Provider (USP). The model optimizing the limited resources, expenditure and operating revenue by using nonparametric analysis (DEA) is proposed.

The obtained results explicitly show that existing resources and how they are used are crucial in achieving the performance outcomes as well as to define the efficient operational plan. Among other, in the case of the USP in Serbia, the results indicate that there is not an excess in the number of employees, while the excess is recognized in the total number of permanent post offices.

- Abstract
The paper centres on the most successful of the numerous attempts to register/recreate the psychedelic experience in film. One of the key assumptions is the fact that there is a strong conceptual link between the cinematic and psychedelic experience and some claim that film is by its nature the most psychedelic of all mediums. The paper also discusses cultural/artistic productions that explored this link. The starting point is also the fact that LSD attracted filmmakers as much as film attracted the psychedelic movement so the cultural fusion between the film and the psychedelia in the 1960s did not happen by chance. The emergence of the New Hollywood, the introduction of new countercultural lifestyles and the use of drugs became an inseparable part of the scene. There is also a parallel story about experimental/avant-garde filmmakers who developed their own aesthetics in line with new acid sensibilities, becoming an inseparable part of the emerging scene of psychedelic mix-media events, where film got to play the central role. The text then takes us to the second part of the 1960s, when psychedelia already imbued the whole spectrum of film productions and when LSD found its place in the background texture of films that otherwise did not centre on the psychedelic movement and up until the moment when LSD in film became a number 1 controversy. This is followed by a discussion about a new generation of experimental/avant-garde filmmakers in the U.S. (New American film), out of which many were involved in the psychedelic movement. Psychedelic feature films focused on simulating the psychedelic experience using film techniques for the purpose of recreating feelings during an acid trip. However, such films aimed at stimulating the sensations of a psychedelic experience further, or rather making psychedelic conditions more intense. This simulation/stimulation was at the core of the attempt of the psychedelic feature film to “extend” the film, extending consciousness at the same time. Of course, this also meant creating an audience that would supplement the new manners of understanding the film through active viewing. [ABSTRACT FROM AUTHOR]

Konačno, na osnovu izvedenih rezultata, dato je obrazloženje zašto predloženi model za merenje troškovne efikasnosti može da bude dragoceno sredstvo za kreatore politike i regulatore iz poštanskog sektora, kao i za menadžere poštanskih operatora. Doktorska disertacija, Predrag V. Ralević vi U disertaciji je predstavljen novi koncept univerzalne poštanske usluge. Suština ovog koncepta je mogućnost da se pošiljalac opredeljuje za uslugu koja bi se obavila u roku do 24 časa od vremena predaje pošiljke na prenos ili za drugu vrstu prenosa koji bi podrazumevao duži rok. Na osnovu toga, predstavljene su tri alternative novog koncepta koje ukazuju da se redefinisanjem univerzalne poštanske usluge može doprineti boljoj diversifikaciji ponude poštanskih usluga. Sa druge strane, u slučaju JPO iz Srbije pokazano je da predloženi koncept nove usluge ima pozitivan uticaj sa stanovišta očekivanih prihoda. To potvrđuju rezultati koji su izvedeni korišćenjem analize vremenskih serija, regresione i korelacione analize, teorije difuzije za prognoziranje tražnje za novom poštanskom uslugom (Basov model), kao i metode upitnika i intervjua. In this dissertation the research subject was to solve the problem of resource optimization of Universal Service Provider (USP). The model optimizing the limited resources, expenditure and operating revenue by using nonparametric analysis (DEA) is proposed.

In the dissertation, a multiple-input and multiple-output model for measuring the cost efficiency (CE) of postal delivery branches is proposed. The complete postal network of the Serbian Post delivery offices, which includes 1,194 post office branches is analyzed.

For illustration, the results of this thesis indicate that, at a minimum, 794 delivery branches could improve their efficiency by resource reallocation. An impact of the economies of scale to efficiency of delivery branches is investigated and it indicates that the economies of scale have a stronger impact on small branches compared to large units. Finally, based on obtained results, the rational of how suggested model for measuring the cost efficiency can be beneficial to policy makers from the postal sector and to company managers is provided. Doktorska disertacija, Predrag V. Ralević viii In the dissertation a new concept of universal service obligation is presented. The essence of this concept is a possibility that the sender choose a transit time for his/her shipment, should it be within 24h or more. Based on that, three alternatives to the new concept are presented and they indicate that can contribute to a better diversification of offer of postal services. On the other hand, in the case of the USP from Serbia is demonstrated that the proposed concept of new service has a positive impact from the standpoint of expected revenue. This confirms the results derived by using time series analysis, regression and correlation analysis, the diffusion theory for forecasting demand for new postal service (Bass Model) as well as interview and questionnaire methods.
