Psychology of a Culture: Humanism and Social Ineffectiveness Embedded in Polish Ways of Life
No full textThis paper is intended as a learning tool for students wishing to expand their knowledge on culture – psychology interaction derived from a single culture perspective. The paper presents a cultural psychology approach to two themes of Polish culture: Humanism and Social (In)-Effectiveness. The text is divided into three distinct parts: (1) A detailed account of a foreigner\u27s encounter with Poland, where standards typical for this culture are introduced; (2) Historical analysis tracing the origins of these two syndromes in Poland; (3) Empirical comparative studies combined over twenty five years, and their meta-analysis

Est-ce la fin de solidarité ?
No full textPAWEL KUCZYNSKI The author inquires about the consequences of the change of political regime in Poland (summer 1989) for Solidarity, which had, until there represented the oppostion against the power of the "State-Party". Growing out of mass strikes in 1980, Solidarity was both a powerful trade-union and a social movement representative of all social strata. Now this counter-power finds itself in an ambiguous position after winning elections and forming a government of its own. As a consequence Solidarity is torn between conflicting missions which must each be assumed, which in turn menaces its very foundations. Nevertheless, the author does not exclude the possibility that Solidarity could find a new identity by drawing conclusions from the present contradictions.Résumé : L'auteur s'interroge sur les conséquences du changement de régime politique en Pologne (été 1989) sur Solidarité qui représentait jusque-là l'opposition au pouvoir de l'Etat- Parti. Née des grèves massives de 1980, Solidarité était à la fois un puissant syndicat et un mouvement social dans lequel se reconnaissaient toutes les couches de la société. Or, ce puissant contre-pouvoir se retrouve maintenant dans une position ambiguë à la suite de sa victoire électorale et de la constitution d'un gouvernement issu de ses rangs. Dès lors, Solidarité se trouve écartelée entre des missions contradictoires qu'elle est tenue d'assumer, au point d'être menacée dans ses fondements mêmes. Toutefois, l'auteur n'exclut pas que Solidarité puisse trouver une nouvelle identité en tirant les conséquences des contradictions actuelles.Kuczynski Pawel. Est-ce la fin de solidarité ?.

Mapping Pawel Pawlikowski and Last Resort
No full textThis article looks at the British-Polish film-maker Pawel Pawlikowski and his film Last Resort (2000). It argues that the film-maker and the film’s main protagonist are prime examples of a postcommunist condition, which has manifested itself since the fall of the Berlin Wall. Drawing on the Bourdieuian concept of ‘cultural capital’, the author claims that Pawlikowski, although a hybrid film-maker, should be considered as a British director, with his cinematic capital bound up in the liturgy of Eastern Europe, particularly Russia. By choosing Margate for his film, Pawlikowski aligns himself alongside iconic film-makers like Lindsay Anderson. Moreover, through this seaside town, he is able to evoke a sense of British decline, which in Pawlikowski’s film melts into an ‘Eastern Europe’ on the coastal fringe of Britain. In Pawlikowski’s film, Margate becomes an example of the postcommunist condition through its abundance of migration, grey housing blocks, surveillance and social misery. If the film-maker is successful in gaining recognition for his cinematic capital as an insider of postcommunism, then his leading heroine fails in her quest for happiness and love in Britain partly because her cultural capital is not recognized. The postcommunist condition is most tangible in Tanya’s migration; however, Alfie, Tanya’s British suitor and saviour, is also part of this global condition, which has engulfed the old Cold War divide. In Last Resort, both East and West function to exhibit a shared postcommunist condition
A sharp multiplier theorem for solvable extensions of Heisenberg and related groups
No full textLet G be the semidirect product N R, where N is a stratified Lie group and R acts on N via
automorphic dilations. Homogeneous left-invariant sub-Laplacians on N and R can be lifted
to G, and their sum is a left-invariant sub-Laplacian on G. In previous joint work of Ottazzi,
Vallarino and the first-named author, a spectral multiplier theorem of Mihlin–Hörmander type
was proved for , showing that an operator of the form F() is of weak type (1, 1) and
bounded on L p(G) for all p ∈ (1,∞) provided F satisfies a scale-invariant smoothness
condition of order s > (Q + 1)/2, where Q is the homogeneous dimension of N. Here we
show that, if N is a group of Heisenberg type, or more generally a direct product of Métivier
and abelian groups, then the smoothness condition can be pushed down to the sharp threshold
s > (d + 1)/2, where d is the topological dimension of N. The proof is based on lifting to
G weighted Plancherel estimates on N and exploits a relation between the functional calculi
for and analogous operators on semidirect extensions of Bessel–Kingman hypergroups
Pawel Jasienica’s philosophy of history : a trial of outlining the topic
No full textThis article is a trial of sketching a few important themes in the philosophy of history of Polish historian and publicist, Pawel Jasienica. Subject to the analysis are mainly parts of his fundamental corpus of works, from "Polska Piastów" ("Poland of the Piasts"), through "Polska Jagiellonów" ("Poland of the Jagiellonians"), to "Rzeczpospolita Obojga Narodów" ("Polish-Lithuanian Commonwealth"). The first
of the topics considered is the ontology of history: its status, its subject (which, as it turns out, is the state), and the historical process. Then, the discussion turns to the ends of history, out of which the most important ones are maintaining sovereignty and the development of culture. The next part of the article is the analysis of numerous "historical factors", shaping the course of history, that Jasienica distinguishes in his works. It ends by considering what possibility of shaping the course of history - both by individuals and by communities - are recognized by our author
Pawel Goral, Cold War Rivalry and the Perception of the American West
No full textIn his first monograph, Cold War Rivalry and the Perception of the American West, Pawel Goral, History lecturer at the University of Texas, Arlington, employs the myth of the American West as a critical lens to address the fascinating, albeit complex, theme of cultural memory and identity-building in Cold-War-divided-Germany. Goral’s thesis argues how the two spheres of political influence shaped opposing views of the Western myth, and how each block respectively deployed it to accommodate their own nationalistic needs. This contributed, the author claims, to fill the cultural void left in the aftermath of the Third Reich, as well as to the formation of a unified sense of Germanness after the fall of the Iron Curtain
Primate dietary ecology in the context of food mechanical properties
No full textSubstantial variation exists in the mechanical properties of foods consumed by primate species. This variation is known to influence food selection and ingestion among non-human primates, yet no large-scale comparative study has examined the relationships between food mechanical properties and feeding strategies. Here we present comparative data on the Young’s modulus and fracture toughness of natural foods in the diets of 31 primate species. We use these data to examine the relationships between food mechanical properties and dietary quality, body mass, and feeding time. We also examine the relationship between food mechanical properties and categorical concepts of diet that are often used to infer food mechanical properties.
Traditional dietary categories, such as folivory and frugivory, did not faithfully track food mechanical properties. Additionally, our estimate of dietary quality was not significantly correlated with either toughness or Young’s modulus. We found a complex relationship among food mechanical properties, body mass, and feeding time, with a potential interaction between median toughness and body mass. The relationship between mean toughness and feeding time is straightforward: feeding time increases as toughness increases. However, when considering median toughness, the relationship with feeding time may depend upon body mass such that smaller primates increase their feeding time in response to an increase in median dietary toughness, whereas larger primates may even feed for shorter periods of time as toughness increases. Our results emphasize the need for additional studies quantifying the mechanical and chemical properties of primate diets so that they may be meaningfully compared to research on feeding behavior and jaw morphology.Peer reviewed
