Progress in the medical diagnostic is relentlessly pushing the measurement technology as well with its intertwined mathematical models and solutions. Mathematics has applications to many problems that are vital to human health but not for all. In this article we describe how the mathematics of acoustocerebrography has become one of the most important applications of mathematics to the problems of brain monitoring as well we will show some algebraic problems which still have to be solved. Acoustocerebrography is a set of (...) techniques of visualizing the state of brain tissue and its changes with use of ultrasounds, which mainly rely on a relation between the tissue density and speed of propagation for ultrasound waves in this medium. Propagation speed or, equivalently, times of arriving for an ultrasound pulse, can be inferred from phase relations for various frequencies. Since, due to Kramers-Kronig relations, the propagation speeds depend significantly on the frequency of investigated waves, we consider multispectral wave packages of the form W = ∑Hh=1 Ah · sin, n = 0,..., N – 1 with appropriately chosen frequencies fh, h = 1,...,H, amplifications Ah, h = 1,...,H, start phases ψh, h = 1,..., H and sampling frequency F. In this paper we show some problems of algebraic and, to some extend, algorithmic nature which raise up in this topic. Like, for instance, the influence of relations between the signal length and frequency values on the error on estimated phases or on neutralizing alien frequencies. Another problem is finding appropriate initial phases for avoiding improper distributions of peaks in the resulting signal or finding a stable algorithm of phase unwinding which is resistant to sudden random disruptions.

Notwithstanding the opportunities it provides, the implementation of some measures of the EU Common Agricultural Policy (EU CAP), including agri-environment-climate measures (AECMs), also generates threats. The study identifies an extremely disturbing process that can be referred to as “internal neo-colonialism”, which has been driven by the technocratic agrarian policy of the EU and transformations in Poland at the turn of the twenty-first century. The associated disadvantageous practices mainly affect areas under threat of marginalisation and peripheralisation, including Poland with its post-Socialist (...) heritage, which has shaped the attitudes and behaviour of society and has consolidated linkages between politics and business. In order to retrace such activities, the study analyses EU funds granted in support of farmers implementing AECMs, with a focus on analysing the place of residence of the “farmer” and the location of the farm. As the research shows, the attractiveness of CAP support causes Polish agriculture and Poland’s countryside, including its natural and financial resources, to be drained by so-called “suitcase farmers”, i.e. people/entities not tied to the place where the agricultural activity is pursued, many of whom live in cities. One common practice is to take over land located in legally protected areas noted for their high quality of natural environment. Not only does the practice of land grabbing strengthen the social exclusion of rural communities and the peripheralisation and pauperisation of these areas, but it also hinders discussion about environmental justice and the ecological integrity of rural areas.

The book presents a collection of articles authored by several members of the Warsaw School of Political Theory, affiliated with the University of Warsaw. The team of scholars, first founded in the 1970s by professor Artur Bodnar, has been conducting research under the leadership of professor Miroslaw Karwat.

Artykuł ma na celu ukazanie wpływu bogatej symboliki „dzikiego męża”, która została według autora opracowania świadomie użyta jako znaczący i jednocześnie uzupełniający element przekazu treści pochodzącej z pierwszej połowy XV wieku _Księgi praw miejskich Głubczyc_ (Codex Iuris Lubschicensis). Analizowany materiał źródłowy stanowi spisany w języku niemieckim zbiór praw miejskich, sporządzony m.in. na bazie łacińskich odpisów, który oprócz bogatych zdobień posiada liczne sceny figuralne. Ich autorem był Jan z Żytawy, iluminator czynny na Śląsku i we Wrocławiu, który ukończył swoją pracę w (...) końcu 1421 lub na początku 1422 roku. W artykule przedstawiono dotychczasową literaturę naukową dotyczącą manuskryptu, uważanego przez długi czas za zaginiony, oraz wykazano, że dotychczasowe opracowania pomijają warstwę symboliczno-znaczeniową przedstawień figuralnych, dostrzegając w nich niepowiązane z treścią rękopisu _drôlerie_. Dodatkowo wskazano na obszerny stan badań na temat „dzikiego męża” w kulturze europejskiej, który dotychczas był pomijany przez badaczy pochodzącego z Głubczyc źródła. W opinii autora opracowania Dzicy Mężowie są ważnym elementem wzmacniającym siłę przekazu całości zbioru praw miejskich i wpisują się w charakterystyczne dla epoki powstania rękopisu opozycje, takie jak: wieś – miasto, prawo stanowione – prawo zwyczajowe, chrześcijaństwo – pogaństwo. Przeprowadzone analizy porównawcze prowadzą do wniosku, że w kulturze europejskiej „dzikim mężom” niejednokrotnie przypadało w udziale kierowanie do ludzi nauk moralnych. Byli oni postrzegani jako uosobienie pierwotnego dobra zaklętego w naturze, a żyjąc z nią w harmonii, pozostali zwierciadłem moralnym dla tych wszystkich, którzy nie uznają jeszcze przepisów zawartych w regulacjach prawnych. „Dziki mąż” to zatem strażnik naturalnego prawa, lub też ducha prawa, co zapewne pragnął oddać Jan z Żytawy, iluminator jednego z najcenniejszych dokumentów przechowywanych obecnie w Archiwum Państwowym w Opolu – w aktach miasta Głubczyc (zespół nr 9, sygn. 122).

This article regards the field of neuroscience and indicates on the proper or erroneous functioning of the human brain. Intellectual virtues, especially practical wisdom play a significant role in capturing the truth and implementing it in life. The agile formation of the cognitive function of man encompasses both his reason as well as the sensual judgment of utility with all the bodily backup. The brain possesses great plasticity in the production of neuronal connections. Habit as a permanent wont utilizes the (...) reactions being developed to the construction of often inappropriate mechanisms, that in turn are not easy or completely impossible to eliminate. When practical reason is introduced into a false ethos, the brain responds by forming “ruts” of neuronal connections which seem difficult to consider as something appropriate. The reparation of the existing situation and the removal of the wrong habit require relevant virtues so as to unblock the psychological resistance that is deeply rooted within the physiological neuronal substrate. The learning about the virtues of St. Thomas Aquinas is the best warranty not only for theoretical explanations, but also for the practical application of virtues in dealing with the arised situation. Only well-formed virtues give the opportunity to correct the false instinctive cognition and liberate from erroneous actions. (shrink)

Starting with the words that finish, or interrupt Master Wincenty’s Polish Chronicle, I interpret its historiographic content as characteristic of 12th century humanism, expression of love, of wisdom. The infallible condition of ethicalarete may be found to be formulated in the last words of the Chronicle concerning humanity which consists in tolerant indulgence of others’ vices and modesty about one’s virtues.

Number 1 of Fides et ratio contains a phrase crucial for the dialogue between science and philosophy. Its meaning is clear in the Latin, polish, English, German, French and Portuguese versions, but it loses its strength in the Italian and Spanish texts.

In art and literature, animals appear not only as an allegoric representation but as a reference which troubles the border between humanity and animality. The aim of this book is to challenge traditional ways of confronting animality with humanity and to consider how the Darwinian turn has modified this relationship in postmodern narratives. The subject of animality in culture, ethics, philosophy, art and literature is explored and reevaluated, and a host of questions regarding the conditions of co-existence of humans and (...) animals is asked: Should discourse ethics now include entities that initially seemed mute and were excluded from discussions? Does the modern animal rights movement need a theology, and vice versa, is there a theology that needs animals? Are animals in literature just metaphors of human characters, or do they reveal something more profound, a direction of human desires, or a fantasy of transgressing humanity? This book provides answers and thus gives a new impetus to a so far largely overlooked field. (shrink)

Niniejszy artykuł stanowi próbę globalnej rekonstrukcji związków, które łączyły Immanuela Kanta z Polską. Część pierwsza zawiera fakty biograficzne dotyczące tego problemu oraz fragmenty wykładów z antropologii, w których Kant mówi o Polsce i Polakach. Podejmuje się też próbę interpretacji fragmentu traktatu Zum ewigen Frieden dotyczącego prawdopodobnie właśnie Polski. Część druga dotyczy rzeczywistych i domniemanych związków filozofa z Polakami.
