Streszczenie:

The studies on beta variability have been fully documented in the literature with various empirical stances, meaning that a concession has not been reached. In view of this we employ the variable Mean Response Regression Model to investigate the random movement of beta coefficients over time and across market phases, using monthly stock returns from Nigerian Stock Exchange (NSE). Our findings based on this model show that beta coefficients move randomly around a trend line when the market is up-beat, whereas they tend to be less volatile in the down market. However, a long-run equilibrium rela

AbstractThe pointwise spectral radii of irreducible matrices whose entries are polynomials with positive, integral coefficients are studied in this paper. Most results are derived in the case that the resulting algebraic function, the beta function of S. Tuncel, is in fact a polynomial. We show that the set of beta functions forms a semiring, and the spectral radius of a matrix of beta functions is again a beta function. We also show that the coefficients of a polynomial beta function p must be real algebraic integers, and p satisfies (after a change of variables if necessary) the inequality f

The price elasticity of demand coefficient for a good or service is a measure of the sensitivity, or responsiveness, of the quantity demanded of a product to changes in the price of that product. The price elasticity of demand coefficients were generated for goods and services in nine different industries for the years 1972 to 1984. A simple linear demand function was employed, using the changes in the Consumer Price Index as a proxy for changes in price and Personal Consumption Expenditures, taken from the National Income and Product Accounts, as a proxy for quantity.

AbstractNormal matrix models, characterised by the requirement that the matrices commute with their adjoint so that their eigenvectors form a unitary matrix, permit an explicit Coulomb gas Boltzmann factor type eigenvalue PDF with $$\beta =2$$ β = 2 , so determinantal structures hold. They permit a simplified global scaling in which the one-body potential is taken as being strictly proportional to N. The support of the corresponding large N equilibrium measure is referred to as a droplet. Perturbing the GinUE one-body potential by the real part of a polynomial leads to a relation between the m

Bacterial cellulose (BC) was investigated as a novel material for preparing activated carbons. BC was dried by heating and it was carbonized with a chemical activation process using phosphoric acid (H₃PO₄) as an activating agent at different temperatures (400, 500 and 600 °C). The properties of the activated carbons were characterized such as chemical property, structure, pore size, thermal property by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), N₂ -physisorption (BET), scanning electron microscopy (SEM) , thermal gravimetric (TGA). The obtained BC activated carbo
