Game-based ratings have received a lot of media attention and managed to capture the interests of many organizations (eg Unilever, AXA Group, Deloitte etc.). In a recent study of human resources practitioners, 75% of participants indicated that they would consider using gamification as part of their own recruitment and selection strategy in the near future. Following the methodological approach already used in educational environment, two approaches to building and using GBA in the organizational environment can be distinguished: gamified assessment-by gamifying (already existing) psychometric test; psychometric play-use of a game to gather evaluation data. It is well accepted that, the basis of the success of any company is due to the human capital, which is the combination of people's capabilities and skills. Therefore, the fundamental job of any recruiter is sourcing talent and engaging employees in the organization. For this, they have to ensure that the candidate's skills match well with the organization's requirement and culture. Previous studies highlighted that those applying for a job are eager to use game-based assessment for self-evaluation, especially when these games are available for free. Game-based assessments can also help maintain a high commitment during the evaluation, which reduces the likelihood of some candidates dropping out in the process and also increases the amount of time that data can be collected. Current paper aim at presenting the preliminary efforts made to gamify two psychometric tests, namely spatial and verbal reasoning.

Knowing the costs of some activity is essential to a financial manager. Within costs it is important to group them into variable costs and fixed costs. The operation of an enterprise generates costs that with the help of the accounting records fail to group costs into the two large categories and a third category of costs arises, namely mixed costs. Mixed costs contain both fixed and variable costs and can only be separated by statistical methods. With the least-squares method, we can make this separation of mixed costs, respecting the conditions imposed by a statistical analysis. Very many use this method without analyzing the parametricity of the data, and the results obtained are of poor quality. In this article we have reviewed the literature on variable, mixed and fixed costs and the statistical model applied. In the research we applied the least-squares regression analysis to the water and sewage operator in Harghita County for the water activity for 2020 and 2019, comparing the results over the two years. The results were also verified with the help of the IBM SPSS analysis program. The conclusion we have reached is that the method of the least-squares is very well applicable for the separation of mixed costs if the data collected at the accounting level are parametric as happens at the regional water operator Harviz S. A., where at the accounting level fixed, mixed and variable production costs are analytically highlighted. The decisions made on the basis of these costs are relevant and enable the undertaking to make the right decisions knowing its break-even point and the fixed costs it can incur. Decisions are also relieved by the fact that fixed costs are highlighted in the two subcategories, namely: short-term fixed costs and long-term fixed costs. As a final conclusion, the decrease in production caused by the reduction in consumption in 2020 did not substantially change the variable costs separated from the mixed costs, so the method used provides support for correct decisions.

The capacity of ecofarms to contribute to the management of the local environment is argued through their complex effects on the rural landscape, climate, waters, atmosphere, biodiversity, and ecological equilibria. The sustainability of the rural landscape is also assured by the improvement of the soils in the ecofarms. This paper reviewed the situation of ecofarms in the world, in Europe, and their perspectives in Romania.

In such an urban centre like Timisoara (the largest one from the West of Romania), the problem of water treatment for drinking, respectively wastewater collection and treatment, have always been issues of strategic importance to the community. The policies of the European Union to support the financing of the member states in the field of environmental engineering and protection represented the basic pillar in the development of the water supply network also in this case. In light of the increasing and pressing need to efficiently manage scarce water resources, there has been renewed interest by water distribution network owners to develop and implement water management strategies and tools that would assist in the integrated and automated management of those networks. The modernizations made at the treatment plants can be summarized in a few basic ideas: the automatic control of processes, lower costs, and higher safety. The most commonly used rehabilitation techniques for reducing both types of water losses are pressure management and pipeline rehabilitation. In Timişoara City, this modernization, and the rehabilitation of the water supply network led to a significant reduction of the environmental pollution (water, soil, air), and to a better protection of human health. Investments in modern technologies for water treatment, which allow an automatic monitoring of the process, translate into more safety in exploitation, and, implicitly, a better-quality control. The main objectives pursued in this study aim at: improving the quality of drinking water supplied to the population, ensuring continuous supply of drinking water, compliance with the regulations in force, both Romanian and European, and ensuring the access for the majority of the population at this system. There were followed the rehabilitation systems for street drinking water supply networks, also those for street sewerage networks, with modern constructive solutions.
