Abstract

The article presents two dimensions of the relationship between cinema and Polish independence. The first part was devoted to the situation of Polish cinema after 1918. I describe the film market, the political situation, relationship between the state and cinematography, films that were then created and their impact on national identity. Then I focus on films in which independence has become a movie theme. I divide them into three periods: until 1939, the People's Republic of Poland and after 1989. I draw attention to their political and historical contexts, functions and film form, and I discuss the meaning and interpretation of each films.

Abstract

On 11 March 2014 Crimea declared independence. Ukraine and international society has not recognised that act. However Crimea’s independence was recognised by Russia and on 18 March 2014 an agreement on the accession of the Republic of Crimea to the Russian Federation was signed. Many countries and international organisations have condemned that step, viewing it as illegal annexation. Regardless of how this situation is treated however, it is at present a fait accompli. Such a situation evokes legal consequences both in the internal law of Ukraine and Russia as well as on the plane of international law. The residents of Crimea appear to be in the worst situation. Legal certainty is a fiction for them now. There are also problems on the international plane. Despite the fact that in the opinion of international society Crimea remains an integral part of Ukraine, in practice there are many conflicting problems of a legal nature that cannot be solved, at least for the time being. This article analyses the legality and certain legal consequences of the “accession” of Crimea to Russia and the effect of this accession on the legal situation for residents of Crimea. The article concludes that legal situation of Crimeans will not improve anytime soon, and that the legal problems which have arisen on the international plane will not be resolved soon either.

Abstract

The international community anxiously awaited delivery of the advisory opinion of the International Court of Justice (ICJ) on Kosovo’s declaration of independence, hoping it would clarify the controversial right of self-determination and the right of secession. Although it was hailed by many as a confirmation of both rights, the advisory opinion was disappointing regarding that part of the analysis which was based on general international law. The ICJ interpreted the question posed in a very narrow and formalistic way. It concluded that declarations of independence (not their consequences) are not in violation of international law, but it did not rule that they are in accordance with international law, as was requested in the posed question. The ICJ refused to examine whether there is a positive entitlement to secession under international law. Although Kosovo and its supporters claimed that the case of Kosovo is unique and will not set a precedent, Russia used the case of Kosovo and the advisory opinion to justify the so-called referendum in Crimea and the subsequent incorporation of Crimea into Russia. However, the situation in Crimea is only superficially comparable to Kosovo and the advisory opinion gives little or no support in the case of Crimea

Abstract

The main focus of this tutorial/review is on presenting Prospect Theory in the context of the still ongoing debate between the behavioral (mainly descriptive) and the classical (mainly normative) approach in decision theory under risk and uncertainty. The goal is to discuss Prospect Theory vs. Expected Utility in a comparative way. We discuss: a) which assumptions (implicit and explicit) of the classical theory are being questioned in Prospect Theory; b) how does the theory incorporate robust experimental evidence, striving, at the same time, to find the right balance between the basic rationality postulates of Expected Utility (e.g. monotonicity wrt. First-Order Stochastic Dominance), psychological plausibility and mathematical elegance; c) how are risk attitudes modeled in the theory. In particular we discuss prospect stochastic dominance and the three-pillar structure of modeling risk attitudes in Prospect Theory involving: the non-additive decision weights with lower and upper subadditivity and their relationship to the notions of pessimism and optimism, as well as preferences towards consequences separated into preferences within and across the domains of gains and losses (corresponding to basic utility and loss aversion), d) example applications of Prospect Theory.

Abstract

To overcome the detrimental influence of α impulse noise in power line communication and the trap of scarce prior information in traditional noise suppression schemes , a power iteration based fast independent component analysis (PowerICA) based noise suppression scheme is designed in this paper. Firstly, the pseudo-observation signal is constructed by weighted processing so that single-channel blind separation model is transformed into the multi-channel observed model. Then the proposed blind separation algorithm is used to separate noise and source signals. Finally, the effectiveness of the proposed algorithm is verified by experiment simulation. Experiment results show that the proposed algorithm has better separation effect, more stable separation and less implementation time than that of FastICA algorithm, which also improves the real-time performance of communication signal processing.

Abstract

Bogusław Wolniewicz, inspired by his formal ontology of situations, has put forward a question on semilattices with a unit (A question about joinsemilattices, Bulletin of the Section of Logic 19/3, 1990). The present paper is entirely devoted to this problem in the formulation given by Wolniewicz. First, the meaning of the question is analyzed and its lattice-theoretical and Boolean algebraic contents are exhibited. Second, set-theoretical and topological counterparts of the question are formulated and commented upon.

Abstract

In education, information and Communications Technologies mostly play the role of a medium of communication, as well as a means of imparting knowledge. ICT, however, is used less as a subject for student activity, i.e. a subject for students to learn, where they can operate the technology, as in robotics or mechantronics. Information technologies are also very rarely implemented in education as a way for students to build their identity and shape their attitudes towards their outside and inside worlds. In spite of this, in the history of educational technology there have been a number of researchers and educators who have promoted interesting ideas for implementing technologies as tools for human cognitive, affective, psychomotor and moral empowerment. Today such people are also present in education, however, they play unimportant roles on the periphery of formal education. This paper is a reminder of a number of ideas by theorists and researchers concerning the implementation of ICT, but mainly highlights the empowerment it gives students and its humanizing/humanitarian role.
