Opis:
Amongst the examples of structures filling up the spectrum of relationships between states and non-state actors in global governance, one can distinguish informal forums of international co-operation. The core position amongst them is occupied by the Group of Twenty (G20). This paper is devoted to the issue of the participation of BRICS in global governance institutions, above all the G20, which develops the summitry process at the political leader and ministerial levels. Attention is drawn to the BRICS group as the leading emerging economies and political powers at the regional and international levels, extending their influence within the G20. This paper highlights the increasing activity of emerging economies in this premier forum of global governance and explores the possibilities of BRICS members developing co-ordinated positions in the G20.(original abstract)

Opis:
Increased geopolitical competition and growing economic nationalism after 2014 have gradually started to slow the trend of liberalization of international trade. Relations among certain national states have turned into trade wars – a hybrid phenomenon shaped at the intersection of geopolitics and geoeconomics. The paper explores global and regional trends in trade regulations introduced by the world’s largest economies and, at the same time, its major military powers. The G20 countries’ role in these processes was illustrated through references to empirical data on the dynamics of the introduced trade regulations in 2009–2018. The effectiveness of the regulations index is proposed. Apart from the harm that deepening such negative trends in the global geostrategic balance does to broader bilateral relations, the role of trade wars in re-shaping globalization’s established conditions is also discussed.

Opis:
During periods of instability, the availability of reserves in the national economy of a country, necessary to overcome crises and repay their negative effects, is of great importance. The economic policy of the G20 countries on the formation of international reserves will give us a general idea of the main trends in this direction. The change in the structure of gold and FX reserves among the group of G20 countries in 2007-2019 is analyzed, the average annual absolute level of gold reserves and their growth have been determined, the amplitude of fluctuations, average deviation and coefficient of variation of gold reserves of the G20 countries have been determined, based on the calculation of the pairwise linear correlation of the gold and foreign exchange dynamics between the G20 countries, the similarities and differences in the implementation of the state policy on international reserves management were determined.

Opis:
The effect of nonmagnetic $Mg^{2+}$ and magnetic $Co^{2+}$ doping in Kagome compounds was investigated using DC magnetic susceptibility. The main effect of doping is to change the crystal field parameters. It was shown that $Co^{2+}$ doping increases considerably crystal field parameters in $Ni_3V_2O_8$ while doping with nonmagnetic $Mg^{2+}$ ions decreases considerably crystal field parameters in $Co_3V_2O_8$ crystals.

Opis:
The paper presents the essence of financial technologies in personal financial planning, especially robo-advice. The main aim of the paper is to describe the presumptions for the development of robo-advice. An analysis of robo-advice on personal finance management was made. The analysis was based on a review of the subject literature, and on primary and secondary research. Particular attention was paid to the intensification of activities in the implementation of modern solutions and tools supporting the management of personal finances and the gradual development of robo-advisors. Modern solutions are still struggling with great distrust on the part of their current and potential customers, and the development of modern technologies in liquidity and asset management still requires a human factor.

Opis:
Magnetic properties of MnAs nanocrystals embedded in GaAs are analyzed in the frame of phenomenological model proposed by Sasaki for ferritin superparamagnets. Our calculations explain qualitatively experimental data of magnetization versus temperature, obtained according to zero-field-cooled and field-cooled protocols. They show dynamics of magnetization of MnAs nanocrystals in range of temperature from 10 K to 320 K. There is transition from state in which very slow dynamics is observed (frozen state) to state in which dynamics is fast (quasi-superparamagnetic state).

For these new samples the results of resistivity and magnetic susceptibility measurements are presented. For BaCuS$\text{}_{3-x}$, K$\text{}_{3}$Cu$\text{}_{8}$Se$\text{}_{6}$ and KCu$\text{}_{3}$Se$\text{}_{2}$ the metal-insulator transition is observed with the low temperature phase being metallic, which is untypical, whereas K$\text{}_{3}$Cu$\text{}_{8}$Te$\text{}_{6}$ is a metal in the investigated temperature range. The temperature dependence of magnetic susceptibility of the studied samples testifies to their diamagnetic or weakly paramagnetic behaviour.

Opis:
The ESR spectrum of Dy$\text{}^{3+}$ ion in the low-symmetry RbDy(WO$\text{}_{4}$)$\text{}_{2}$ crystal has been studied in the temperature region of T=4.2 ÷ 30K. The ESR linewidth was found to increase from 130 mT up to the maximum value of 190 mT at T=9K and then to decrease down to 150 mT at 4.2K. The components of the g-tensor change considerably without change of their spatial orientation in the temperature range from 12K to 7 K: g$\text{}_{z}$=2.5, g$\text{}_{x}$≈0, g$\text{}_{y}$=1.41 at T>12 K; g$\text{}_{z}$=1.53, g$\text{}_{x}$≈0, g$\text{}_{y}$=1.2 at T<7K. The observed λ-shaped behaviour of absorption linewidth and the decrease in the g-factor are assumed to be due to the low-temperature structural phase transition (T$\text{}_{SPT}$≈9 K). The width of the transition area is of about 5K. It is suggested that the symmetry of high- and low-temperature phases is identical.

Opis:
Suicides represent an encompassing measure of psychological wellbeing, emotional stability as well as life satisfaction, and they have been recently identified by the World Health Organization (WHO) as a major global health concern. The G20 countries represent the powerhouse of global economic governance and hence possess the ability to influence the direction of global suicide rates. In applying the sequential panel selection method (SPSM) to three generations of unit root testing procedures, the study investigates the integration properties of suicides in G20 countries between 1990–2017. The results obtained from all three generations of tests provide rigid evidence of persistence within the suicides for most member states of the G20 countries, hence supporting the current strategic agenda pushed by the WHO in reducing suicides to a target rate of 10 percent. In addition, we further propose that such strategies should emanate from within G20 countries and spread globally thereafter.
Samobójstwa stanowią wszechstronną miarę dobrego samopoczucia psychicznego, stabilności emocjonalnej, a także satysfakcji z życia, a ostatnio zostały uznane przez Światową Organizację Zdrowia (WHO) za główny problem zdrowotny na świecie. Państwa G20 są potęgą w obszarze globalnego zarządzania polityką gospodarczą, a tym samym mają zdolność wpływania na kształtowanie się globalnego wskaźnika samobójstw. Stosując metodę SPSM do trzech generacji testów pierwiastka jednostkowego, w opracowaniu zbadano własności integracyjne samobójstw w krajach G20 w latach 1990–2017. Wyniki uzyskane ze wszystkich trzech generacji testów dostarczają mocnych dowodów na utrzymywanie się samobójstw w większości państw członkowskich G20. Uzasadnia to istnienie aktualnego programu strategicznego forsowanego przez WHO, zmierzającego do redukcji odsetka samobójstw do docelowego poziomu 10 procent. Wskazano ponadto, że takie strategie powinny rozprzestrzeniać się z państw G20 na pozostałe państwa świata.

Opis:
The idea of electron wave packets moving along closed anisotropic Fermi surfaces placed in a constant magnetic field has been applied to the calculation of the orbital magnetic moment of an individual free electron and tightly-bound s-electron in a crystal lattice. In each case the magnetic moment is obtained as a derivative of the electron energy done with respect to the strength of the magnetic field. In the next step, calculations have been extended to electron ensembles. For a free-electron ensemble a thorough calculation of the weak-field magnetic moment gives a result similar to that obtained by a well-known method developed by Landau. On the other hand, calculations done for the s-band of the tightly-bound electrons of metallic iron give an absolute value of the magnetic moment much smaller than in the free-electron case. Simultaneously, the sign of the moment is changed indicating a lowering of the iron band electron energy with magnetization.

The UV-vis-NIR and electrical properties of $Yb_{8-x}Y_xV_2O_{17}$ for x=0, 2, and 8 were investigated. The band energy gap of 2.6 eV determined for $Yb_6Y_2V_2O_{17}$ (x=2) and comparable for the remaining compounds with x=0 and 8 is characteristic for insulators. Low electrical conductivity with a characteristic minimum shifting to higher temperatures from 322, via 360 to 370 K in the sequence x=0, 2 and 8, which decreases with increasing content of ytterbium was observed. Temperature dependence of thermoelectric power showed n-p transition at 410 and 467 K for x=0 and 2, respectively, and n-type conductivity for x=8, indicating mainly n-type electrical conductivity. A breakdown voltage of 26 V/mm is mainly observed for the I-V characteristics at 400 K and showing a varistor-like behavior.

$Fe_{1-x}Cr_xVSbO_6$ solid solution is semiconductor with the activation energy decreasing both in the intrinsic and extrinsic conductivity temperature regions as the Cr-content increases. The n-type conduction is observed for Fe-richer samples while a change of the Seebeck coefficient (from n to p) - for Cr-richer ones. Magnetic isotherms for all samples of solid solution under study are characteristic of the universal Brillouin function, indicating paramagnetic response. These effects are discussed within the framework of the appearance of the mixed valence of both Fe and Cr ions.

The I-V characteristics and the conductance G at 300 and 400 K showed symmetrical and nonlinear behavior in the voltage range (-100, 100 V) suggesting the electron emission over the potential barrier especially for the boundary compounds FeSnSbO₆ and CrSnSbO₆. These effects are discussed in the context of the energy gap $E_{g}$>1.6 eV many times greater than the thermal energy kT.

Opis:
The electrical conductivity σ (T) and thermoelectric power S(T) measurements of Sr₂InV₃O₁₁ showed the insulating state and the change of sign of thermopower from p to n at $T_{n-p}$=400 K. The I-V characteristics provided the evidence of symmetrical and non-linear behaviour typical of strong emission of charge carriers induced by temperature and voltage. Relative dielectric permittivity $ε_{r}$ as well as loss tangent (tan δ) strongly depend both on the temperature in the range of 295-400 K and the frequency in the range of 5×10² to 1×10⁶ Hz, showing the broad maximum at 320 K. These effects are considered as a relaxation process like in the Maxwell-Wagner or Jonscher model as well as the conduction of electric current, as determined by the Joule-Lenz law.
