Structural changes and economic growth of the Republic of Serbia: The effects of applied structural adjustment models

There is a general consensus in the economic literature that there is a strong correlation between structural changes and economic growth: structural changes are the most significant repercussion of economic growth, but at the same time, in the long run, it's most important factor. Having in mind this fact, the analysis of structural changes and economic growth of the Republic of Serbia is a key research issue on which this paper focuses. In that sense, the paper, based on relevant theoretical knowledge and reference statistics on the movement of basic macroeconomic indicators, monitors and analyzes the effects of applied models of economic growth in the process of structural adjustment of the economy of the Republic of Serbia during the first two decades of the 21st century, in which major, and in some sub periods, specific structural changes took place.

Self-similar turbulent vortex rings: interaction of propellant gases with blood backspatter and the transport of gunshot residue

Self-similar turbulent vortex rings are investigated theoretically in the framework of the semi-empirical turbulence theory for the modified Helmholtz equation. The velocity and vorticity fields are established, as well as the transport of passive admixture by turbulent vortex rings. Turbulent vortex rings of propellant gases originating from the muzzle of a gun after a gunshot are an important phenomenon to consider in crime scene reconstruction. In this work, it is shown that this has a significant repercussion on the outcome of backward blood spatter resulting from a gunshot. Turbulent vortex rings of propellant gases skew the distribution of bloodstains on the ground and can either propel blood droplets further from the target, or even turn them backwards towards the target. This is revealed through the final bloodstain locations and the respective distributions of the number of stains and their area as a function of distance from the target for two different shooter-to-target distances. An image of the propagating muzzle gases after bullet ejection is overlaid with the predicted flow field, which reveals satisfactory agreement. Gunshot residue is an important factor in determining the events of a violent crime due to a gunshot and are considered to be entrained and transported by the propellant gases. The self-similar solutions for the flow, vorticity and concentration of gunpowder particles are predicted and the results are shown to be within the measured range of a limited set of experimental data.

Ética e direitos humanos no trabalho de assistentes sociais na Saúde | Ethics and human rights in the work of social workers in healthcare

O Conselho Federal de Serviço Social (CFESS) vem, nas últimas décadas, construindo iniciativas para fomentar o debate ético-profissional e dos direitos humanos em diversas frentes de intervenção. Desta forma, o presente artigo analisa as repercussões da ação política do CFESS no campo da ética e dos direitos humanos no cotidiano de trabalho de assistentes sociais do Sistema Único de Saúde (SUS). Neste sentido, o artigo é fruto de uma pesquisa realizada com profissionais de Mossoró (RN), concluída em 2017. Constatamos que as ações promovidas pelo CFESS têm uma significativa repercussão e vêm ganhando materialidade no cotidiano de trabalho dos assistentes sociais, reforçando o posicionamento ético-político defendido pelo Serviço Social brasileiro nas últimas quatro décadas.Palavras-Chave: ética; direitos humanos; Serviço Social; saúde. Abstract – In the last decades, the Federal Council of Social Work (CFESS) has been implementing initiatives to promote ethical-professional and Human Rights debate on several fronts. In this sense, this article analyzes the impact of CFESS’s political action concerning ethics and Human Rights in the daily work of social workers of the Unified Health System (SUS). The article is the result of a survey carried out with professionals from Mossoró, Rio Grande do Norte concluded in 2017. We find that the actions promoted by CFESS have a significant repercussion and are gaining materiality in the daily work of social workers, reinforcing the political-ethic positioning advocated by Brazilian social work over the last four decades.Keywords: ethics; human rights; social work; healthcare.
