Waste Management and Research | Year: 2016

Waste collection and transport can generate up to 70% of the total costs of the system. Separated collection of recyclables implies additional costs for which the sale of recycled waste often does not compensate, but there is increased pressure to reach the long-term recycling objectives set by law. The proper estimation and monitoring of waste collection costs are essential to define the most cost-effective waste collection system. The aim of this study is to propose and implement a management tool to determine waste collection costs for different waste collection schemes. Based on input data, such as waste quantity and composition, the number of waste bins, the location of collection points, the type of collection vehicle, crew, collection route, etc., the developed tool can calculate the time and costs of waste collection (per vehicle, collection point or tonne of collected waste). This tool uses Excel spreadsheets and it was tested on a district in the central area of the city of Kragujevac to calculate the costs of waste collection for two scenarios: Collecting all waste as mixed waste, and collecting separately recyclables and residual waste. The developed tool can be useful for municipal solid waste management companies, since it allows benchmarking and variance analysis. © 2016 The Author(s). Source

In this paper the impact of political risk on the movement of stock prices in the capital market of the Republic of Serbia is analysed. This is the market with a short history of trading, characterized by a high degree of volatility, with frequent and high jumps in prices. In addition, it is a very narrow and depth lacking market dominated by share trading in that period; the market where the trading in neither treasury, nor corporate bonds was well-developed. All stipulated above indicates a high degree of correlation between the stock price and the current local political events, with the exception of the financial crisis as a global factor. Serbian political shocks are frequent, unpredictable and well defined, which allows us to clearly identify political risk. We have identified the dates/periods when certain jumps in the volatility of the market index return happened, which were then brought into connection with the occurrence of appropriate political news. In that way we were able to quantify the effects of political events on the volatility of return. This is the first paper that deals with the impact of political risk on stock returns in Serbia. Additionally, it is shown that Serbia’s score of political risk in December 2009 was the highest in the Eastern Europe region. In 2015 it is around regional Balkan’s average, and it lies between Albanian and Macedonian score of political risk index. © 2016, Kauno Technologijos Universitetas. All rights reserved. Source

Applied Energy | Year: 2013

The main aim of this paper is to review of the current state of energy systems in the Western Balkans countries. The paper gives a review of the individual parameters relating to energy development, defines the current state of the achieved level of sustainable energy development as a whole and defines possible strategic directions for energy development in the region. The paper also examines the possibility for implementation of the adopted EU target of 20% RES energy production. The main characteristics in the region are high energy consumption, high values of carbon emission, fossil fuels import dependency, constant production and electric energy supply, and high potential but minimal RES energy production. Further development of regulation framework and market liberalization is are basic preconditions of demanding energy reform in all countries. Increasing energy the second energy development priority. The third long term strategic goal is increasing the amount of the energy obtained from hydro and transition to clean coal technologies. Intensifying RES production is currently the fourth strategic priority. The analysis shows that production of energy from wind is priority for the region, but currently it is constrained by too great investment requirements for developing countries. © 2012 Elsevier Ltd.

While labour market research is not a new phenomenon, interest in it is growing. Literature frequently discusses changes in the market as separate disciplines, isolated from each other. On the other hand, it can be found that more and more scientists understand and choose interdisciplinary research as a powerful tool for understanding, critique, explanation and change. But some of these approaches have difficulty accounting for change and the co- existence of similarity and diversity, as well as being 'gender blind'. This article critically reviews a range of theoretical approaches to employment research and practice using the lens of feminism. The appropriate integration of gender awareness into mainstream theorizing, is advocated alongside its separate development. In addition, in this article we provide a multidisciplinary approach and attempt to integrate important aspects (knowledge, education, entrepreneurship, self-employment and informality, employment and globalization) that the analysis of labour market and research puts forward. In the light of this assessment, this paper sets out to indicate potentially useful approaches for conducting employment research in the future, where gender is a core component of analysis. Such approach aims to act as a catalyst to provoke a more extensive debate on this topic. Source

This paper presents the importance and specifics of applying the concept of target costing as an instrument of formation the realistic selling prices, improving competitiveness and managing business performance in retail companies. We strive to present complex-both theoretical and empirical-dimensions of applying the concept of target costing in retail companies. Within this framework we indicate not only the advantages but also certain limitations of applying the concept of target costing in retail companies. The reports are based on the analysis of the original practical examples, mainly retail companies from countries with developed market economies, in which the concept of target costing is substantially applied, especially in new services and products development, as it is the case, for instance, with the famous Swedish furniture company IKEA. Theoretical and practical knowledge systematically developed in this work should primarily serve as a fundamental framework for efficient application of the concept of target costing as a function of determining the realistic selling prices, improving competitiveness and business performance of modern retail companies. This is particularly true of retail companies in countries where the application of new concepts of cost management, including the calculation of target costs, is made only to a certain extent, as is the case with Serbia and many other countries in the region and beyond.
