Description:
In this paper we investigate the global convergence result, boundedness and periodicity of solutions of the recursive sequence xn+1 = a0xn + a1xn−1 + . . . + akxn−k ⁄ b0xn + b1xn−1 + . . . + bkxn−k , n = 0, 1, . . . where the parameters ai and bi for i = 0, 1, . . . , k are positive real numbers and the initial conditions x−k, x−k+1, . . . , x0 are arbitrary positive numbers.

2. Světy se zrcadlem: marginalizace a integrace z hlediska sociopsychologické dynamiky společnosti

Subject:
Roma, Roma settlements, marginalisation, social integration, socio-psychological dynamics, and Slovakia
Language:
Czech
Description:
This article looks at the marginalization of the Roma from the perspective of socio-psychological dynamics of society. The author takes the specific case of Roma settlements in Slovakia, where he has conducted anthropological research, to illustrate how the mechanism of marginalisation functions. Drawing on the work of Tzvetan Todorov and Peter L. Berger, he argues that at the heart of human sociability - the ability and necessity to live among others - is the constant human need for attention and recognition from others. This basic human need affects the socio-psychological dynamics of society, including the marginalisation as well as integration of some of its groups. This need for attention and recognition leads to the emergence of complex 'counterworlds' or 'counter-societies', with their alternative value systems. The Roma settlements and urban ghettoes represent such counter-worlds that provide their inhabitants with attention, recognition, positive self-interpretation, and confirmation of their values. If the inhabitants of these counter-worlds are unable to fulfil this need anywhere else, then their integration into wider society cannot be achieved.

3. Zrození moderního umělce a kritika v Čechách: umění, věda a objevení času

Description:
In his article, Jaroslav Anděl traces the changes that took place in both art and science in the Czech Lands in the course of the 19th century. In the works and commentaries of such painters as Karel Purkyně or Soběslav Pinkas, he finds early signals of the emergence of modern art. Even the scientific findings of Karel Purkyně’s father, J. E. Purkyně, a renowned natural scientist of his era, divulge links to modern art-forms, such as cinematography. The exchange between art and science is apparent, for example, in the geological inspiration for Adolf Kosárek’s paintings. What is particular about such works and scientific endeavors is their disruption of the static imagery and emphasis on the flow of time. The rise of urbanism and, consequently, of individualism, brought the passing and linear conception of time to the fore. Anděl claims that this “discovery of time” was a crucial element in constituting both the modern artist and critic., Jaroslav Anděl., and Obsahuje bibliografii
