Most theoretical and empirical studies concerning intercultural communication seem to neglect the fact that numerous interlocutors’ speech and nonverbal behaviour is intentionally impolite and motivated by their racist and/or xenophobic views, which becomes visible in contact with representatives of other cultures, nationalities or countries. Such speakers’ behaviour may take the form of physical attacks, while their linguistic performance may include verbal/nonverbal signs of their prejudiced stance. Linguistic performance which is motivated by aggressive nationalism, intolerance or discrimination is termed hate speech. The available scientific literature on this topic is scant, except for some studies fuelled by the theoretical assumptions of critical discourse analysis. There are apparently no clear and precise criteria what constitutes an act of verbal and nonverbal violence. The authors of this paper aim therefore at portraying characteristic features of hate speech in Polish on the basis of articles collected throughout 2014 and 2015 from newspapers, magazines and Internet sites. The analysis took place as part of the RADAR project devoted to conducting research on hate speech directed towards migrants in Europe. The findings indicate there is a wide repertoire of words and phrases that are visible in Polish journalism and which promulgate racial, national or ethnic hate.

Weed competition in southern Brazil is one of the main limiting factors for Oryza sativa L. (flooded rice) yield. Echinochloa spp. (barnyardgrass) occurs at a high frequency. Although the potential for weed interference in this cereal is well known, there is little information available about the impact of nutrient competition on rice. Thus, this study aimed to evaluate the relationship between the increase of the barnyardgrass population and the development and nutrition of flooded rice plants at different stages of development. The treatments consisted of growing populations of barnyardgrass competing with the crop from stage V4, which were: 0, 1, 6, 13, 100 and 200 plants · m−2. The experimental design was randomized blocks with two replications, and the experimental units were plots 1.53 m wide by 5 m long. Plant biomass, nutrient uptake and loss of productivity were determined with three replications. An increase in the barnyardgrass population reduced the dry mass of rice leaves and stems, regardless of the evaluation period and the vegetative or reproductive period. Barnyardgrass plants had a significant impact on the reduced grain yield of a flooded rice crop, mainly due to high nutrient competitiveness, especially N in the vegetative period and K in the reproductive period. Barnyardgrass caused a loss of yield by unit · m−2 of 1.13%. The competition for N between rice and barnyardgrass plants was higher in the vegetative period, while for K, Ca and Mg the highest competition occurred in the reproductive period.

Successions exposed in the Agadir Basin (upper Albian to middle Turonian), in the Anti-Atlas (lower Turonian) in Morocco and in central Tunisia (Cenomanian–Turonian) yield abundant microcrinoids of the family Roveacrinidae, which are described and assigned to 32 species and formae, in ten genera. The following new taxa are described: Fenestracrinus gen. nov. with the type species F. oculifer sp. nov., Discocrinus africanus sp. nov., Styracocrinus rimafera sp. nov., Lebenharticrinus quinvigintensis sp. nov., L. zitti sp. nov., Euglyphocrinus cristagalli sp. nov., E. jacobsae sp. nov., E. truncatus sp. nov., E. worthensis sp. nov., Roveacrinus gladius sp. nov., R. solisoccasum sp. nov. and Drepanocrinus wardorum sp. nov. In addition, the new subfamily Plotocrininae is erected. The stratigraphical distribution of the taxa in two important localities, Taghazout in the Agadir Basin (Morocco) and Sif el Tella, Djebel Mhrila (central Tunisia), is provided. The faunas from the uppermost Albian and lowermost Cenomanian of the Agadir Basin are nearly identical to those recorded from central Texas, USA, some 5,300 km away, and permit a detailed correlation (microcrinoid biozones CeR1 and CeR2) to be established across the southern part of the Western Tethys, independently supported by new ammonite records. For the middle and upper Cenomanian, rather few detailed records of microcrinoids are available elsewhere, and the North African record forms the basis for a new zonation (CeR3–CeR6). The distribution of Turonian Roveacrinidae in North Africa is evidently very similar to that described in the Anglo-Paris Basin, and zones TuR1–3, TuR9, 10 and 14 are recognised for the first time in the Tethys.

The main problem in theoretical analysis of structures with strong confinement is the fact that standard mathematical tools: differential equations and Fourier’s transformations are no longer applicable. In this paper we have demonstrated that the method of Green’s functions can be successfully used on low-dimension crystal samples, as a consequence of quantum size effects. We can illustrate a modified model through the prime cubic structure molecular crystal: bulk and ultrathin film. Our analysis starts with standard exciton Hamiltonian with definition of commutative Green's function and equation of motion. We have presented a detailed procedure of calculations of Green's functions, and further dispersion law, distribution of states and relative permittivity for bulk samples. After this, we have followed the same procedures for obtaining the properties of excitons in ultra-thin films. The results have been presented graphically. Besides the modified method of Green’s functions we have shown that the exciton energy spectrum is discrete in film structures (with a number of energy levels equal to the number of atomic planes of the film). Compared to the bulk structures, with a continual absorption zone, in film structures exist resonant absorption peaks. With increased film thickness differences between bulk and film vanish.

In this study, the effect of six commercial biocontrol strains, Bacillus pumilus INR7, B. megaterium P2, B. subtilis GB03, B. subtilis S, B. subtilis AS and B. subtilis BS and four indigenous strains Achromobacter sp. B124, Pseudomonas geniculate B19, Serratia marcescens B29 and B. simplex B21 and two plant defense inducers, methyl salicylate (Me-SA) and methyl jasmonate (Me-JA) were assessed on suppression of wheat take-all disease. Treatments were applied either as soil drench or sprayed on shoots. In the soil drench method, the highest disease suppression was achieved in treatment with strains INR7, GB03, B19 and AS along with two chemical inducers. Bacillus subtilis S, as the worst treatment, suppressed take-all severity up to 56%. Both chemical inducers and bacterial strains AS and P2 exhibited the highest effect on suppression of take-all disease in the shoot spray method. Bacillus subtilis S suppressed the disease severity up to 49% and was again the worst strain. The efficacy of strains GB03 and B19 decreased significantly in the shoot spray method compared to the soil drench application method. Our results showed that most treatments had the same effect on take-all disease when they were applied as soil drench or sprayed on aerial parts. This means that induction of plant defense was the main mechanism in suppressing take-all disease by the given rhizobacteria. It also revealed that plant growth was reduced when it was treated with chemical inducers. In contrast, rhizobacteria not only suppressed the disease, but also increased plant growth.

The aim of this paper is to consider the not so well investigated problem of the role that language has played in Karl Marx’s thinking. The first section discusses several examples of Marxist attempts at philosophical or linguistic reflection on language. I propose the thesis that Marxist meaning theory did not seriously evolve due to the domination of the ‛Traditional Meaning Theory’ (TMT) – irrespective of the actual social conditions. In the second section I undertake some adumbrations on the tendencies of contemporary philosophy of language, such as externalism or pragmatism, whose premonitions can be found in Marx. I also point out that combined with historical materialism they can no longer fit TMT. Finally, I argue that the notion of language and the division of linguistic labor may solve some issues of Marx’s conception of ideology.

The article presents a relation between a word and a picture against a background of art theology developing in Christianity. Such an assumption releases from the presentation of a selection of illustrations to biblical texts. Assumed deliberations have a form of an outline illustrated by the examples from the field of miniature painting and engraving, depicting in a literal sense a transformation of a word into a picture. The studies from the field of a word function in faith tradition created the whole theological and biblical literature. On the other hand analyses of the analo- gical role of a picture in Christianity are relatively new and only seldom are they conducted by theologians or art historians.

The title of the present dissertation constitutes a travesty of a sentence announced by St. John in the prologue of his Gospel: "And the Word was made flesh" (1:14). When John is talking about the Logos it means in our perspective a written word, that is the Revelation described in the Bible. Based on what St. Paul said in the Letter to the Romans (10:14-18) the expression: Fides ex auditu started to be used in theology. The question of the role of a picture in religion can be encapsulated in a paraphrase of this expression, as: Fides ex visu. Certain people in specific circumstances acquire faith through the sense of sight, through image.

The Prophets attributed to pictures magic forces and the power of influencing human souls. Therefore they pushed them into the field of magic and witchcraft, into the world of dark forces, using signs. According to their teaching a real cult does not need any material signs. A monotheistic religion wants to remain a religion based on reading and not watching „suspicious" pictures. Rejecting visual representations, the Old Testament favours verbal symbols. And not only has the image of a false godbecome the idol, but also a false image of the true God. The invisible God can be described, but not painted. Art is too weak to show the greatness of God. The undescribed God remained invisible. He made himself known to people only through the revealed word and depicting Him in paintings was forbidden because it was a threaten to the primary Plan of Salvation. In such an approach a word becomes a power and the rejected picture becomes weak because it is useless and even harmful. This was well expressed by Re'gis Debray, who wrote that art with its altars, paintings and figures was too heavy to be carried by the Jew, this eternal wanderer, on his way. Thus he took the book.

Despite strict bans we can find in the Old Testament statements containing human longing for watching God, either during the sleepas in the case of patriarch Jacob, or in a „face-to-face" meeting as Moses at Mount Sinai, or in a prophetic seeing as it was experienced e.g. by Isaiah, Jeremiah, Ezekiel, Daniel, or the other ones „seeing".

The situation changed in the New Testament, when the eternal Logos - the son of God became a man. It was possible to see God through the incarnate Word, as Jesus Christ became the most ideal icon of God. The incarnation gave a possibility of depicting the one that was so far Invisible. This can be contained in a sentence that „the Word was made a picture". The Mystery of the Incarnation was invoked by the iconodules at the Second Council of Nicea, in 787.

Christianity is a religion of a word and a picture, but Protestants are different from Catholics in their approach to pictures. Taking a doctrinal assumption on the sole primacy of a word (sola Scriptura), certain sections of the Reformation rejected a picture as a form of superstition. The specific character of Protestant art became the custom of placing citations from the Bible on paintings, or even placing the sole citations or the sentences of the Reformation in altar reredos.

The subject of this article are the Egyptian inspirations in the graphic works of Ewa Siedlecka-Kotula, an artist living and working in Kraków in the second half of the 19th century. During the period from May 1948 until June 1949 she resided in Cairo, a productive period which came to fruition in the form of a special cycle of linocuts, executed in 1969 and based on earlier sketches. The series comprises of the following works: “Kobiety/Women”, “Woda/Water”, “Ryż/Rice”, “Tkacze/Weavers”, “Pasterka/ Female shepherd”, and “Barany/Rams”, depicting contemporary Egyptians and their typical, everyday tasks. During her stay in Egypt the artist also designed the exhibition graphics for the 16th Agricultural and Industrial Exhibition in Cairo. Her works were put on display at an individual exhibition (December 1948). She also participated in the exhibitions entitled “Le salon des femmes-artistes” in Cairo Women’s Club (March 1949) and “France-Égypte” in the Museum of Modern Art in Cairo (May 1949). Ewa Siedlecka-Kotula’s works met with much interest at that time. Unfortunately, references to antiquity are very scarce in her art, and include only a watercolour showing an Egyptian peasant by a shaduf (fig. 1), and a drawing of a female offering-bringer figurine from the tomb of Nakhti, overseer of the seal, in Asyut (early 12th dynasty, around 1900 BC). The latter drawing was perhaps made in the Egyptian Museum in Cairo, and most likely represents a statuette whose current fate remains unknown, which would make this drawing an exceptional record.
