Facebook Versus Moodle in Practice

Very few research papers and case studies have shown successful integration of both Facebook and Moodle in the educational experience of students. This study sought to evaluate the educational benefits of the increasingly popular Facebook—which plays an important role in students’ social life as well as their academic life—and to compare it with the widely used course management system Moodle. In this study, the authors surveyed students of the University of Belgrade’s Faculty of Organizational Science in Serbia on their attitude toward Facebook and Moodle as productive online tools for teaching and learning. An analysis of the results was carried out using the SPSS software package. The results of this research answer the question of whether or not using Facebook as an educational tool is more effective than using Moodle and how it affects students’ everyday learning activities.

EPI: Environmental Feedback on the Organization’s Sustainability

The turning point that was paramount in environmental issues was the publication of the 1987 report of the World Commission on Environment and Development, Our Common Future, as well as the UN Conference on Environment and Development (UNCED) held in Rio de Janeiro in June 1992. Sustainable development is a global development management philosophy that aims to conserve the integrity of the Earth’s ecosystems while supporting economic growth and social welfare. The concept of Sustainable Development first appeared in the 1970s and early 1980s (IUCN, 1980) but only came into prominence following the 1987 World Commission on Environment and Development report (Seke et al., 2013). Therefore, societies and businesses need to make a drastic shift to a sustainable socio-economic system with fewer negative environmental impacts. The prevailing opinion nowadays is that good environmental performance makes good business and organization sense.

The model of risk assessment of greywater discharges from the Danube River ships

Having in mind the immense value of the Danube River and knowing that risk assessment of its pollution is one of the key elements for ecology and the health of people in its region, in this paper we emphasized the importance of risk assessment of ship-generated wastewater – particularly in the case of greywater discharges. Although, a number of methods for measuring and analysing different environmental risks have been developed, previous research shows that the failure mode and effect analysis (FMEA) method is applicable in solving environmental issues. Therefore, we conducted our research with the main purpose to develop a model of FMEA method application for assessing the risks of ship-generated greywater discharges based on estimated data for total quantity of greywater, the size of the exposed population to the pollution of greywater and the possibilities of this pollution detection. Risk analysis was performed on official data for nine ports on the Danube River on inland waterways of the Republic of Serbia. Based on the obtained results, we concluded that measures, recommendations and risk prevention strategies for ship-generated greywater discharges should go into two major directions: (1) decreasing the pollution caused by greywater discharges; (2) increasing the number of water quality monitoring stations.
