(Title in Polish - 'Specyfika, znaczenie i funkcja wytworów koscianych i rogowych w kulturze magdalenskiej na przykladzie stanowiska Wilczyce 10, pow. Sandomierz'). The Wilczyce site in southern Poland was discovered during a field survey conducted in 1994 as part of the Archaeological Map of Poland. Regular excavations carried out from 1998, first by Dr. Jan Fiedorczuk and after his death by Prof. Romuald Schild, have revealed that the products of Magdalenian Culture were distributed within an ice wedge. Of the 147 bone, ivory and antler objects with traces of processing 54 could be recognized as artifacts: 3 figurines, 12 points, 2 intermediary tools, baton, 2 smoothers (lissoirs), chisel, 2 awls, scoop-smoother, 2 handles, 24 needles, plaque and 3 unidentified objects. They were all produced of reindeer antler, mammoth tusk ivory and bone. The most spectacular of all because of their uniqueness were the points and handles . The production process is best exemplified by needles made of horse bone in a technique requiring first splinters to be cut and then sectioned perpendicularly. The two different types of sagaies points and forms with hollowed ventral side called for a different production technique. In the former case, rectangular pieces were sectioned off a halved piece of antler, in the latter, the ventral side was dressed until compact bone was reached, giving an arched cross-section in effect. The bone and antler implements from Wilczyce represent Magdalenian IV, confirming the theory that settlement in central Europe can be related for the most part to the upper and terminal phases of this culture.

In the last decades, the Internet has developed into a proliferating and flourishing source of information. This phenomenon requires complex pieces of writing to be presented in a way that expedites their efficient processing. This paper presents an experiment studying how text presentation affects reading efficiency and text recall. We compared different types of text presentations - scrolling and text pagination with and without callouts. A word recognition task was used to assess the recognition of a presented text. Discrepancies in reading efficiency were apparent in the results obtained from the eye tracking data; namely, we noted that scrolling is more demanding than reading paginated text in terms of the processing time. Our findings provide support for claims of more efficient processing of paginated texts. Such text presentation appears to have a strong influence on cognition that should be taken into account by designers whenever visualizing complex texts online.

The complex phenomena in a global knowledge-based society and economy are causing difficulties in understanding by conventional modes. The economists should consequently analyse new phenomena. They need to build new theories and disseminating them to wide community. New results in cognitive sciences and progressing ICT, advances in applied informatics and computational intelligence there are arising new opportunities for a dialogue with mental models and theories in the economic sciences. In economics the creation of virtual laboratories and of simulation experimentation with them is useful, for the author uses name “Economic Softbot”. He refers to the dialogue with such softbots as storytelling. The topic of the essay belongs to the class of emergent research/education/learning technologies. Their innovative power is in the dominance of constructive upon instructive approaches and based on holistic qualitative perception of the various complexities.
