Aliasing-Free and Additive Error in Mixed Spectra for Stable Processes. Application: Sound of a Bird just captivated in stress

2022

Consider a symmetric continuous time α stableprocess observed with an additive constant error. Theobjective of this paper is to give a non-parametric estimatorof this error by using discrete observations. As the time ofprocess is continuous and the observations are discrete, weencountered the aliasing phenomenon. Our process sampleis taken in a way to circumvent the difficulty related toaliasing and we smoothed the periodogram by using JacksonKernel. The rate of convergence of this estimator is studiedwhen the spectral density is zero at origin. Few long memoryprocesses are taken here as examples. We have applied ourestimator to the concrete case of modeling noise of a birdcaptured under st…

"Demokracja jacksonowska" a zmiana postawy legitymizacji władzy sądowniczej w USA

2021

The article discusses the issue of changes of the bases of legitimization for the state judiciary in the US during the so-called “Jacksonian Democracy”, i.e., the period from 1829 (the beginning of the presidency of Andrew Jackson) until the outbreak of the Civil War. During this period on the wave of the democratization process of public institutions in the US, popular elections were introduced to select judges at the state level. The reason for the introduced institution was the willingness of legal environments to make judges independent from the world of politics, as well as strengthening their social authority and a political position in a political system. The result of popular electi…
