Various properties of classical Dedekind sums $S(h, q)$ have been investigated by many authors. For example, Wenpeng Zhang, On the mean values of Dedekind sums, J. Théor. Nombres Bordx, 8 (1996), 429–442, studied the asymptotic behavior of the mean value of Dedekind sums, and H. Rademacher and E. Grosswald, Dedekind Sums, The Carus Mathematical Monographs No. 16, The Mathematical Association of America, Washington, D.C., 1972, studied the related properties. In this paper, we use the algebraic method to study the computational problem of one kind of mean value involving the classical Dedekind sum and the quadratic Gauss sum, and give several exact computational formulae for it.
Ve svém příspěvku autorka vychází z dlouholeté praxe psychologa působícího
v republikových bezpečnostních sborech. Věnuje se tématům individuální a skupinové identity v prostředí totalitní a posttotalitní společnosti a bezpečnostních institucí. and In her contribution the author builds upon her longstanding experience as a psychologist in Czech security forces. She discusses the themes of individual and group identity in an environment of totalitarian and post-totalitarian society and security institutions.
Penyamun is a central figure of rumors of public construction sacriface rumors and head-hunting rumors that have been recorded in Southeastern Asia since beginning of the 20th century. The aim of the present article is to analyze the present-day form of such rumors on the island of Sumba in eastern Indonesia. All rumors discussed herein focus on the figure of penyamun, a foreigner yearning for body parts or blood of the inhabitants of Sumba.
