The persuasion of vaccine allocation models during Covid-19. Rhetoric, ethics and science

The swift development of effective vaccines against the new coronavirus was an unprecedented scientific achievement. In this paper, we discuss what models have been proposed for distributing vaccines locally and globally through the application of Aristotelian rhetoric. This discussion, therefore, focuses on a specific question: how are the different models of vaccine administration and distribution justified on an ethical-argumentative level? This report also examines what has come to be known as “vaccine nationalism” through the lens of the early experience with the COVID- 19 vaccination process. To this end, this report proceeds as follows: Section I explains the rhetorical method applied to ethical principles, and Section II explains the chosen criteria for the analysis. Section III looks at the Fair Priority Model; Section IV examines the COVAX and GAVI model; Section V presents the weighted lottery model. Section VI proposes a summary table of the analysis of the proposed models and Section VII focuses on the ethical problem of vaccine nationalism and its implications in relation to the models, that were taken into consideration during the previous sections. Section VIII offers brief conclusions; solidarity conceived as an argument of reciprocity should be, according to this analysis, the guiding value to address ethical problems in the area of resource allocation.

EKONOMSKA NEJEDNAKOST U VREME PANDEMIJE

In this paper the author presents the overview of the impact of the Covid-19 pandemic on the global economic trends with the focus on the economic inequalities. The Covid-19 pandemic that has caused the global recession, has also brought to the surface the issue of global inequalities, particularly exposing the economic inequalities. The Kuznets curve, a scientific achievement in the field of economics, as originally formulated suggests that the level of inequality is low when an economy’s income is at low level, that is, the income inequality increases with economic development and then tends to decline when the country attains a higher income level. However, the sustainability of Kuznets curve is questioned today in the current circumstances of global information society struck by pandemic. Modern economic literature views the contemporary growth of inequality in wealthy countries, as well as in developing countries, through the prism of Kuznets cycles or waves. The growing trend in global inequalities may threaten the attained level of economic growth and scientific and technological progress.

Kinematic analysis of Felix Baumgartner's stratospheric jump in 2012

The present investigation shows a kinematic analysis of Baumgartner’s stratospheric jump, based on a scientific report by Red Bull. The modeling was carried out using the different forces that intervened in the event (velocity, acceleration, etc.), making it possible to generate a mathematical model capable of extrapolating data and allowing us a better appreciation of such scientific achievement. All the mathematical exploration has been carried out with ten decimal places; however, they will be rounded to four in writing. The action plan was based on obtaining the velocities by placing points on a velocity model belonging to an approximate graph of a Red Bull scientific report, which was put into the GeoGebra Classic 5 program to find the velocities. After this, we proceeded to find the accelerations and the formula of the function that models them. Finally, this formula was integrated to acquire the mathematical model of the velocities.

Glazunov’s electrography—the first electrochemical imaging and the first solid-state electroanalysis

Aleksandr Il’ich Glazunov developed the first electrochemical technique to image the surface of conducting solids giving the technique the name electrography. The electrographic images can mirror the distribution of elements on the surface of solid materials and also the electrochemical activity, caused by variations of “dissolution tension”. Thus, he has established for the first time a kind of spatially resolved electrochemistry. Electrography is also the first direct electroanalytical technique for solid materials. The present paper gives an account of his turbulent life in Russia, Czechoslovakia and Chile, and a discussion of his main scientific achievement, the development of electrography.

Conceptions of Suryaya Identity in the Sixth to Ninth Centuries

This chapter deals with the ways in which Muslim rule changed Jacobite conceptions of the past. It explores Dionysius' innovative discussion of the relationship between language, ethnicity, and ancient history, which was highly influential for his successor Michael the Syrian. It also charts the use of ethnic language in John of Ephesus, the Chronicle of Zuqnin, and Dionysius. The chapter situates their changing usage in the context of immigration by new ethnic groups and the development of a discourse of ethnicity that emphasized kingship. It considers the existence of a second discourse of ethnic prestige, namely scientific achievement, which Dionysius was probably aware of but deliberately avoided because of its pagan connotations.

Assessment of Concentration of Mineral Oil in Synthetic Ester Based on the Density of the Mixture and the Capacitance of the Capacitor Immersed in It

This research was carried out during the realization of a project with the aim of developing a method of drying cellulose insulation in power transformers by using synthetic ester. Unfortunately, during the drying process, the ester is systematically contaminated with mineral oil, which reduces its water absorption. Information on the oil concentration in the mixture is needed in two cases: when deciding how to treat the mixture, and during the treatment. The article presents two methods: (1) based on the measurement of the mixture density, and (2) based on the measurement of a capacitor immersed in the mixture. The most important scientific achievement of the work is the proof, by way of experiment, of the existence of a relationship between the concentration of mineral oil and (1) the density of the mixture, and (2) the capacity of the capacitor immersed in it. These relations are presented in the form of equations for which the error calculus showed that the uncertainty of measurement for both methods did not exceed 3 p. %. Due to the similar measurement error of both methods, the authors recommend the capacitance method as easier to use, especially online.
