The aim of the paper is to test the effect of climatic conditions and management practices on the yield of two quinoa cultivars (Puno and Titicaca) and to analyze the economic benefits of quinoa productivity. The experiments were carried out during the 2017 and 2019 growing seasons in rain-fed conditions on a Serbian farm. The results of the two-year long experiments proved that the growing of the quinoa cultivar Puno and particularly the cultivar Titicaca in the agro-ecological conditions of Serbia would be remarkably successful from the aspect of agronomy (with the obtained average yield of 2.5 t ha-1 ) as well as from the aspect of economy (with the achieved average profit of 9,411 € ha-1 ). The obtained profit values indicate that the quinoa production in the Republic of Serbia would be more cost-effective than the production of the field crops which are already produced, particularly in the increasingly present arid conditions.

On the basis of a cost-benefit analysis it was decided to expand the Arnsberg WWTP by a multistage biological process which allows for cost-effective integration of the existing facilities. Carbon removal will then be accomplished in a high-loaded activated sludge stage for which the existing primary clarifier is to be reconstructed. The existing trickling filters will be used for nitrification during a midterm period and will be replaced later on either by a moving bed system or by new trickling filters. Line 3 of the existing secondary clarifiers will be reconstructed and used for post denitrification in a moving bed system. The carbon needed for denitrification will be provided by means of sludge hydrolysis and the use of an external carbon source.

We conducted the first cost-benefit analysis of a federally financed, comprehensive early childhood program. The Title I Chicago Child-Parent Centers are located in public schools and provide educational and family support services to low-income children from ages 3 to 9. Using data from a cohort of 1,539 program and comparison-group children born in 1980 who participate in the Chicago Longitudinal Study, measures of program participation were significantly associated with greater school achievement, higher rates of high school completion, and with significantly lower rates of remedial education services, juvenile delinquency, and child maltreatment. Economic analyses indicated that the measured and projected economic benefits of preschool participation, school-age participation, and extended program participation exceeded costs. In present-value 1998 dollars, the preschool program provided a return to society of $7.14 per dollar invested by increasing economic well-being and tax revenues, and by reducing public expenditures for remedial education, criminal justice treatment, and crime victims. The extended intervention program (4 to 6 years of participation) provided a return to society of $6.11 per dollar invested while the school-age program yielded a return of $1.66 per dollar invested. Findings demonstrate that an established public program can provide benefits that far exceed costs. Key elements of CPC program effectiveness include an instructional focus on literacy, opportunities for intensive parent involvement, and implementation by well-trained staff within a single administrative system.

The main objective of this paper is to present the advantages of using Cost-Benefit analysis in energy efficiency projects implemented in public buildings, and to prove the hypothesis that Cost-Benefit analysis boosts the effectiveness and efficiency of the said type of projects. The paper offers theoretical and practical explanation of the implementation of Cost-Benefit analysis in the relevant area. Since energy efficiency projects in public buildings usually represent a part of a broader portfolio of similar projects and their implementation demands allocation of substantial financial resources, communities are often be interested in achieving maximal economic and non-economic benefits. This paper aims to demonstrate that Cost-Benefit analysis can represent an excellent contribution when attempting to select the projects for implementation within a broader portfolio of energy efficiency projects in public buildings. This hypothesis was demonstrated by putting a greater emphasis on non-economic benefits and the costs arising from implementation of the aforementioned types of projects. In addition, a practical test of this hypothesis was performed through the implementation of an energy efficiency portfolio in public buildings, worth several tens of millions of dollars - the Serbian Energy Efficiency Project. The paper concludes that the use of Cost-Benefit analysis can help us to effectively evaluate and manage projects of this type aimed at achieving maximum benefits for the community in question.

This study is intended to evaluate the feasibility of introducing a single loop-based vehicle detector in preparation for installing the device for permanent traffic volume counts by segment. Existing AVC comprises two loop sensors and one piezo sensor which are costly for installation. Should the vehicle classifications be similar within the section, reliable traffic data collection would be possible using a single-loop alone, which needs to be evaluated. For this, traffic volume and vehicle classifications collected by two AVCs within a section were analyzed with cost-benefit analysis for analyzing the feasibility of applying a single loop-based vehicle detector . As a result of comparing and analyzing the vehicle type ratio in 36 sections where two AVCs are installed respectively, 90% of the total showed the error rate 15% or less, and according to T-test and correlation analysis result, no statistical significance between two locations in vehicle type ratio was found. According to economical feasibility analysis, B/C 12.19, NPV 474.0 bil and IRR 196%. Thus, collection of vehicle type ratio from one AVC in the section and installation of a singl loop-based vehicle detector in a single section would produce more efficient and cost effective count. Further study on cost and benefit through more intensive statistical analysis would be necessary in the coming days.
