The objective of this article is to further examine Nordic media systems beyond the tenta- tive Democratic Corporativist Model introduced by media scholars Daniel C. Hallin and Paolo Man- cini in their important work Comparing Media Systems. Three Models of Media and Politics. Further- more, the article discusses distinct features of media and politics-relations in the Nordic countries and attempts to identify key factors constraining or promoting a possible liberalization or hybridization of the media systems in Nordic countries. The empirical data is based on a secondary analysis of avail- able media statistics in Denmark, Finland, Norway and Sweden. A comparative approach is used to analyze whether the Nordic countries actually meet the standards of the Democratic Corporativist Model or if they are drifting towards a more liberal media model. The main conclusion of this article is that the Nordic media systems are becoming more liberal due to diminished influences from gov- ernments and political parties. However, traditional Nordic media institutions remain strong and have been successful in adapting to new conditions thus creating new hybrids of the Nordic and the Lib- eral media models.

Rab7 is a small GTPase that plays a crucial role in the regulation of transport from early to late endosomes and lysosomes, phagosome maturation and in lysosomal biogenesis in mammalian cells. It contains conserved and unique sequence elements that mediate its function. Two Rab7 genes, Rab7a (703 bp) and Rab7b (707 bp) were identified in the unicellular eukaryote Paramecium by PCR amplification. They contain three short introns of different lengths (28-32 bp) and sequence located at identical positions in both genes. The presence of two Rab7 genes in the Paramecium genome was confirmed by Southern hybridization analysis performed with six different restriction enzymes. Expression of both genes was assessed by Northern blot and RT-PCR. Two transcripts of 1.8 and 2.2 kb were identified by hybridization analysis. The cloned complementary DNAs, both of 618 nucleotides in length, encode polypeptides of 206 amino acids that are 97.6% identical and differ in their C-termini. The predicted protein sequences of Rab7a and Rab7b contain all characteristic domains essential for Rab function: the effector domain (YRATVGADF) and four GTP-binding consensus sequences (GDSGVGKT, WDTAGQ, NKLD, SAK) as well as the prenylation motif (-CC) at the C-terminus indispensable for Rab binding to the membrane. Similarity searches revealed 81.6-82.1% homology of Paramecium Rab7 isoforms to human Rab7 and a lack of an insert typical for the Kinetoplastida - the species that appeared earlier in evolution. Paramecium is the first free-living lower eukaryote in which homologues of Rab7 have been identified that exhibit features similar to those of mammalian Rab7.

A cDNA clone encoding an amphioxus fatty acid binding protein-like (AmphiFABPL) protein was isolated from a gut cDNA library of Branchiostoma belcheri. It contained a 423 bp open reading frame corresponding to a deduced protein of 140 amino acids with a predicted molecular mass of approximately 15.9 kDa. Phylogenetic analysis showed that AmphiFABPL fell outside the vertebrate clade of fatty acid binding proteins (FABPs), being positioned at the base of the chordate lineage, and was almost equally homologous to various vertebrate FABPs, suggesting that it may be the archetype of vertebrate FABPs. Both northern blotting and in situ hybridization analyses demonstrated that AmphiFABPL was expressed in the hepatic caecum and hind-gut, and although at a much lower level, it was also present in the endostyle, ovary and testis. In addition, whole-mount in situ hybridization revealed that AmphiFABPL was initially expressed in the posterior two thirds of the primitive gut, including the mid-gut where the hepatic caecum will form later, in 2-day larvae. The expression pattern is closely similar to that of the L-FABP and I-FABP genes in vertebrates, supporting the hypothesis that the hepatic caecum in the amphioxus is homologous to the vertebrate liver.

Five different di-O-alkylated pentaerythritol phosphoramidite building blocks (2a–e) were synthesized and introduced into oligonucleotides to obtain mass-tagged probes (6a–f) useful in RNA transcription profiling. These non-nucleosidic mass tags allow categorization of oligonucleotide probes having identical nucleoside content and, hence, identification of the probe hybridized to RNA by mass spectrometry analysis. Hybridization properties of the oligonucleotide conjugates were elucidated by melting temperature measurements.

This article discusses the development of election campaign communications in Sweden. The article analyzes whether political campaign communication in Sweden is heavily influenced by international trends, and if some distinctive national features still prevail. The mixture of liberal and social responsibility media system traditions in the Swedish society is used as a theoretical point of departure. Additionally, empirical data from the latest Swedish national elections on party communi- cation, media coverage and web communication are presented and new communication trends are analyzed.

Artykuł podejmuje kwestię konstruowania dwóch różnych modeli męskości obecnych na kartach Trans-Atlantyku Witolda Gombrowicza. Konfrontacja anachronicznej polskiej męskości sarmackiej z nowoczesną innością męskości południowoamerykańskiej owocuje w powieści rewizją polskiej formy narodowej, umożliwiając rozszczelnienie granic pojęcia męskości, zamkniętej w europocentrycznych definicjach. Kulturowa odmienność argentyńskiego mężczyzny wobec mężczyzny polskiego okazuje się możliwa do uchwycenia za pomocą teorii postkolonialnych. Autor analizuje teksty Gombrowicza, używając takich pojęć, jak „hybrydyzacja męskości” (Eduardo Archetti) czy „męskości plebejskie” (Pablo Ben). Idea Ojczyzny, która w powieści jest silnie sprzężona z męskością hegemoniczną i narodową ideologią, została zderzona z koncepcją Synczyzny, opartej na modelu męskości plebejskiej, hybrydycznej, niepoddającej się dyskursom normatywizującym i nacjonalizującym. Polska męskość sarmacka, ukazana na tle kultury argentyńskiej jako eksces, pozwala autorowi wysnuć tezę o kampie męskim, a nawet sarmackim.

EN

The article takes up an issue of structuring two different models of masculinity that are presented on the pages of Gombrowicz’s novel. Confrontation of anachronistic, Polish, Sarmatian masculinity and modern otherness of South American masculinity results in revision of Polish national forms. It enables unsealing the limits of the notion ’masculinity’ which is closed in Eurocentric definitions. Cultural diversity of Argentinian and Polish men might be expressed by postcolonial theories. The author analyses Gombrowicz’s texts and uses terms, such as hybrid masculinity (Eduardo Archetti) or plebeian masculinities (Pablo Ben).The idea of homeland is strongly connected with hegemoniczna masculinity and national ideology. It is faced with the concept of Synczyzna (Sonland) that is based on a model of demotic and hybrid masculinity and becomes the subject of normativizing and nationalizing discourse.Polish Sarmatian masculinity presented in comparison to Argentinian culture seems to be the excess and it allows the author to draw a conlusion about masculine camp, or even sarmatic one.

W pracy przedstawiony jest algorytm typu podziału i ograniczeń dla problemu sekwencjonowania przez hybrydyzację z błędami negatywnymi oraz częściową informacją o powtórzeniach. Uwzględnienie tego rodzaju informacji możliwe jest ze względu na rozwój technologii stosowanej w eksperymencie hybrydyzacyjnym. Prowadzi ono do rozszerzenia standardowej wersji metody sekwencjonowania przez hybrydyzację oraz do polepszenia jakości uzyskiwanych rozwiązań.

The article contains a report of the second research workshop of our Euro-Identities project. The workshop took place immediately after collecting first data (pilot interviews). On the base of the digital recording of all sessions, the protocol carefully attempts to reconstruct the proceedings of the research workshop as a social arrangement for the generation of analytical knowledge. Therefore it can be read as a reconstruction of – in the sense of Alfred Schütz’ perspective of “Making Music Together” – “how to do together” analysis of autobiographical narrative interviews. The report dwells on the questions of how to get a first impression of the interviews, of how the European phenomenon is addressed in them and, of how to do the research steps of formal text sort analysis, structural description, analytical abstraction including the reconstruction of the overall biographical structuring and contrastive comparison. Although at this stage of analysis it is not dealt with the research step of constructing a theoretical model, phenomena of social worlds and social arenas, of European opportunity structures, of networking and establishing of social relationships, of transnational comparison, of transgressing cultural borders, of new professional initiatives and professional hybridization and of a non-essentialist self-identification with Europe are found.

W artykule przedstawiony został drugi warsztat badawczy poświęcony analizie materiałów w projekcie Euroidentities. Spotkanie, które miało miejsce zaraz po ukończeniu zbierania wywiadów pilotażowych zostało nagrane i dzięki temu możliwe było sporządzenie dokładnego protokołu. Zapis warsztatu jest przykładem rekonstrukcji – w rozumieniu Alfreda Schütza – ‘jak robić razem’ analizę wywiadów biograficzno-narracyjnych. W artykule została zwrócona uwaga na następujące kwestie: znaczenia pierwszego wrażenia z lektury wywiadu, odpowiedzi na pytanie badawcze w jaki sposób pojawia się w nim temat Europy, jak realizować procedurę badawczą – strukturalny opis tekstu, analityczną abstrakcję, porównania kontrastowe. Chociaż na tym etapie pracy nie tworzy się modeli teoretycznych zwrócono uwagę na takie zjawiska jak: światy i areny społeczne, europejskie struktury możliwości, tworzenie sieci relacji społecznych, specyficzny typ identyfikacji europejskiej.
