Social costs today: institutional analyses of the present crises. An introduction
No full textThis book deals with the causes of the present crises but it claims that causes and policy implications cannot be properly assessed by focusing on allocative efficiency or income growth alone; it contends that a more general approach is called for, based on social costs. It does not deal with social costs according to the Pigouvian or the Coasian traditions. It draws on the work of Original Institutional Economics (OIE) such as Thorstein Veblen, Karl William Kapp and Karl Polanyi, on post-Keynesians such as Hyman Minsky and, in general, on authors who have provided insights beyond the conventional wisdom of economic thought

Minimizing the condition number of a positive definite matrix by completion
No full textElsner L, He C, Mehrmann V. Minimizing the condition number of a positive definite matrix by completion. Numerische Mathematik. 1994;69(1):17-23.We consider the problem of minimizing the spectral condition number of a positive definite matrix by completion: [GRAPHICS] where A is an n x n Hermitian positive definite matrix, B a p x n matrix and X is a free p x p Hermitian matrix. We reduce this problem to an optimization problem for a convex function in one variable. Using the minimal solution of this problem we characterize the complete set of matrices that give the minimum condition number

Relation of skewness factor and convection velocity in turbulent boundary layer
No full textThe paper is devoted to prove the relation between skewness factor and convection velocity in turbulent boundary layer. It appears that skewness factor can be used as an indicator of convection velocity of coherent structures, which is not always equal to the average flow velocity. The analysis has been performed based upon velocity profiles measured with hot-wire technique in turbulent boundary layer with pressure gradient corresponding to turbomachinery conditions. The results show that the cross product term of skewness factor decomposed by spectral filtering, which is also alternative measure of amplitude modulation, describes the convection velocity in zero pressure gradient turbulent boundary layer

Valentino Fioravanti and the Duet from the Opera ‘Echo W Lesie’ [An Echo in the Woods] by Wojciech Pękalski and Józef Elsner
No full textJeden z sześciu numerów jednoaktowej opery Echo w lesie, dotychczas uznawanej za dzieło Józefa Elsnera, w rzeczywistości wykorzystuje muzykę duetu „Con un aria schizzinosa” z opery Il furbo contra il furbo Valentina Fioravantiego, w praktycznie niezmienionej postaci. Zapożyczenie, choć sygnalizowane na premierowym afiszu, dotąd nie zostało zidentyfikowane. Odkrycie to przekreśla niektóre tezy stawiane przeze mnie w artykule „Echo w lesie Józefa Elsnera i Wojciecha Pękalskiego – późny pogłos włoskiego intermezza na warszawskiej scenie narodowej?” (Muzyka 65 (2020) nr 2), choć zarazem dodaje nowe argumenty za uznaniem premierowego pochodzenia zachowanej partytury Echa.One of the six numbers in the one-act opera Echo w lesie [An echo in the woods], previously considered to be the work of Józef Elsner, actually uses music (in a virtually unaltered form) from Valentino Fioravanti’s opera Il furbo contra il furbo (the duet ‘Con un aria schizzinosa’). The borrowing, although acknowledged on the poster for the work’s premiere, has remained unidentified until now. This discovery invalidates some of the theses of my own paper titled ‘Echo w lesie Józefa Elsnera i Wojciecha Pękalskiego – późny pogłos włoskiego intermezza na warszawskiej scenie narodowej?’ [Józef Elsner and Wojciech Pękalski’s An Echo in the Woods: a late reference to Italian intermezzi in the repertoire of Warsaw’s National Theatre?] (Muzyka, 65/2, 2020), but at the same time contributes new arguments in favour of recognising the preserved score of Echo as that used for the work’s premiere
