A B S T R A C T Insufficient export activity and low level of investment in the formation of gross domestic product are a negative feature of the Serbian economy over a longer period of time. The global financial and economic crisis has shown that a sustainable model of economic growth, which was basically based on the growth of domestic consumption and imports and a low share of investments in the structure of the use of GDP, is an unsustainable until then. It has become clear that such a model must be replaced by a pro-investment and export-oriented model of economic growth. Bearing in mind the trends in macroeconomic flows in the Serbian economy, it is clear that the increase in investment and the competitiveness of domestic production imposes itself as one of the most important tasks of economic policy in the future. In this sense, the main goal of this.

The main aim of this paper is to perform efficiency and productivity analysis of Universal Service Obligation (USO) based on the Malmquist Productivity Indices (MPI) analysis. The study focuses on 29 Designated Operators (DOs) and two isolated periods, the years 2003 and 2017. There is a clear trend of workforce reduction (12%). Considering the postal services, the data confirm a general trend that the letter-post is in decline (30%) and the parcels are on the rise (52%). Considering the financial results, both costs and revenues are increased; however, there is a higher increase of revenue (33.13%) compared to the cost (32.61%). Further, the results of implemented methodology are twofold. Firstly, a progress is determined at the average level of all observed DOs according to the efficiency and productivity indicators. Among other, the results indicate the increase of productivity for both input MPI (3.5%) and output MPI (8%). However, there are significant variations of efficiency and productivity at the individual level. Secondly, the aim of research was also to examine the sources of productivity changes by considering postal market liberalization, ownership, marketing services and e-commerce. Our findings show that the last three specified variables contribute to the explanation of productivity change.

The paper examines the memoir The Book of My Lives by Bosnian-American writer Aleksandar Hemon. This non-fiction work explores the author's childhood in the capital of Bosnia and Herzegovina before the collapse of Yugoslavia, and then his exile experience in Canada and the United States after the outbreak of the war. Through the prism of memory, the book deals with the subject of exiles, uprootedness and efforts to start a new life in a new environment. Being an autobiographical record, The Book of My Lives lends itself to the examination of the issue of exile and memory issues, which is one of the two themes of this paper. The second concerns the understanding of the relationship between memory and space. The paper seeks to show how the spatial dimension is also important for the creation of memory because memories represent an essential factor for the transformation of abstract space into a particular place.
