Content available remote O Nowej to Hucie refleksja - kulturowe konteksty miejsca po Leninie
PL
Nowa Huta - wzorcowy przykład socrealistycznego miasta idealnego, część Krakowa, niegdyś nowoczesna i tętniąca życiem, od czasu transformacji 1989 r. ulega stopniowej degradacji. W artykule przedstawiono nowe formy i próby aktywizacji tego miejsca. Autorki zastanawiają się, czy i w jaki sposób Nowa Huta może pełnić dziś funkcję "serca miasta". Potencjał urbanistyczny i historyczny tego miejsca zasługuje na powszechne zauważenie i docenienie. Czy dziś nieuchronnie wiąże się to z upowszechnieniem, uproszczeniem znaczenia i komercjalizacją?

Nowa Huta - a model example of a socialist realism ideal city, part of Kraków, once modern and teeming with life, gradually degraded since the 1989 transformation. The article presents some new forms and attempts to activate this place. The authors debate if and how Nowa Huta can act as "the heart of the city" today. The urban and historical potential of the place deserves general attention and appreciation. Must it be related to dissemination, the simplification of its meaning and com-mercialization these days?

Prezentowane opracowanie stanowi część szerzej zakrojonych studiów nad tak zwanym aleksandryjskim, antycznym detalem architektonicznym. Podjąłem je na terenie wykopaliskowym w Marinie, niedaleko el-Alamein, w północnym Egipcie, gdzie od kilkunastu lat są prowadzone przez polskie i egipskie misje badania archeologiczne i konserwacja reliktów hellenistycznego miasta i nekropolii1. Osada, której relikty odkryto w Marinie, jest identyfikowana na podstawie antycznych opisów wybrzeża Morza Śródziemnego z miastem Leucaspis i portem Antiphrae [5, s. 14-16], [12, s. 108-118]. Na podstawie znalezisk oraz wyników badań sądzić można, że funkcjo-nowała ona w długim okresie od II w. p.n.e. do VI w. n.e. [3, s. 12], [10, s. 5]. Domy mieszkalne, w ich głównej masie, w najstarszej fazie roboczo można datować na koniec I i na II wiek [8, s. 117-154], chociaż są również znajdowane nieliczne relikty pochodzące z czasów wcześniejszych. Później, chociaż niewiele zmieniało to ich układy, również domy były przebudowywane. Czas powstania struktur, w których były umieszczone opisywane nisze, jest jednak określany na koniec II i na III stulecie. Podobnie na 2. połowę II wieku lub początek III stulecia jest określany na podstawie stylistyki czas wykonania polichromii, która pokrywała wnętrze jednej z nisz.

Studies of the antique socalled Alexandrian architectonic detail, are the subject of this article. The results of these studies, in the area of archeological excavations in Marina near El-Alamain in north Egypt, have been presented. They were carried out on the examples of wall niches (aedicula), situated in representative accommodations, called an andron, of antique Greek-Roman houses. In Marina, relics of five such niches were found, variously preserved and allowing reconstruction in different degrees. A sixth niche is known to have existed. The architectonic setting of the niches was created by elements of the Corinthian order in its particular modification, described as Alexandrian. Simplification and stylization is characteristic to it. The architectonic detail stylized in this manner was earlier called Nabataean. This was due to the discovery of the first examples in Petra (the land of the Nabataeans). The special architectonic order occurring there is still the Nabataean. It also appears in Marina, in Cyprus and in the region of Alexandria. However, more frequent in those places is the occurrence of three similarly stylized, different orders. They correspond to the classic Doric, Ionic and Corinthian orders. It is lately believed that Alexandria and the neighbouring region was the centre where these forms took shape. Hence, the definition of these orders as Doric, Ionic and Corinthian in the Alexandrian modification. The framework of the niches described was executed in the Corinthian order. These niches being small objects, on the borderline between sculpture and architecture, allow us almost complete reconstruction. This is why they constitute a better material for studies on the arrangement and architectonic proportions of an order than objects of a larger scale and more monumental. Such are, for exampie, the columns and other portico elements only partly preserved in Marina. After finding the elements of a complete aedicula and its reconstruction, studies aiming at recreating the canon of construction of the Alexandrian-Corinthian order were undertaken by the author, in the years 1999-2000. For a more convincing recreation of these rules an analysis of more than one object is necessary. It has been conducted in this article. The proportions of several niches and individual elements of portico columns have been compared. All the niches compared had an almost identical architectonic arrangement of the framework. On either side, on the sill, were placed attached columns, which stood out from the wall face. From the interior side of the niche each column had a flat pilaster of the same height and properties. On the capitals of the attached columns and pilasters and inside the niches, against the wall, rested architraves. In plan they had the shape of a horseshoe embracing the aedicula from three sides. Above the architraves there were no friezes, apart from one niche. Higher up, were mouldings. They ran around the niche, repeating with their outline the architraves' arrangement. On the bottom surfaces of the mouldings, extending beyond the architraves, a stylized decoration was placed. It had the form of simplified consoles or an offset profile composed of such consoles, squares and sometimes rhombs. One of the niches had a moulding of classic forms. The edges of the tympanums rested on the outer, extreme sections of the mouldings. They were triangular or arched. The comparison of the niches' proportions showed that they all had the same ratio of attached columns' height to the diameter of their base and to the width of the niche. The height of the attached columns was nine times the diameter of the base and equal to the whole framework of the aedicula. The ratio of their height to the distance between thtm was also constant for all the niches described. This was not dependent on their size. The distance between the largest and the smallest niche differed fivefold. Obviously, there must have existed a canon of constructing the architectonic order, which created the niches' framework. Such a canon also existed in the classic Corinthian order. It has been described by Vitruvius and comparison with his description was the basis of reconstructing of the Alexandrian-Corinthian canon. This canon, as it appears, was not always fully respected. Sometimes, in small objects, an attempt was made to make up for the small proportions of the whole by increasing the size of certain elements. It was so in the case of the aedicula from the house denoted as H10, reconstructed in the years 1999-2000. Proportions of the orders creating the settings of the other niches are more regular, very near to the classic, Vitruvian proportions and recurring in all of them, A drawn reconstruction presents the theoretical measurements of the canon of the Alexandrian-Corinthian order.

This paper tests the recent published synthetic theory of biodiversity of Ritchie and Olff (1999) using data on parasitic Hymenoptera and soil living Diptera. Neither the predicted size dependent size ratio patterns, nor the left skewed species number-size class ratios, nor right skewed species richness-productivity patterns were found. It is concluded that the basic assumptions of the theory (self similarity of habitat, food, and resource distribution over ecological relevant scales) is not applicable at fine scales and to guilds of higher trophic levels. Whether in general the assumptions are applicable to plants and phytophages has to be decided by further studies.

Content available remote Relative abundance distributions of species : the need to have a new look at them
EN
This paper shows that recent models of relative abundances (RADs) like the log-normal model or sequential breakage or nich apportionment models are not able to describe and explain RADs found in natural communities because they are derived from a classical niche concept and assume strong past or present interspecific competition. None of them refers especially to temporal variability and functional niche dimensions. The present paper identifie three basic features of natural communities (unimodal species-weight distributions, abundance-weight distributions with more or less marked upper boundaries, and species density fluctuations that can be modelled by four different random processes). Modelling communities with these basic features resulted in RADs that only in part could be described by classical models but that had shapes often found in sampling from larger natural communities. No single distribution like the canonical log-normal appeared that may serve as a general null-model but RAD and evolutionary strategy (r- or K selection) seem to be related. The shape of relative abundance distributions was found to depend on the number of species even if all parameter setting of the generating distributions were identical. This indicates that classical evenness indices (that assume independence of species number) might not be appropriate to compare communities with different numbers of species. It appeared that RAD and body weight related community patterns have to be studied together.

In a beech forest on limestone (Northern Germany) community structure and coexistence of a community of phorid (Diptera) parasitoids (Aspilota and Orthostigma spp., Hymenoptera, Braconidae) was studied. A classical niche analysis including character displacement, temporal and spatial segregation and density fluctuations could not clearly separate the species. In a case where such a separation by morphological factors was possible, hosts and spatial distribution of this species were the same as in morphologically different species. As prediced from aggregation theory of coexistence all species were highly aggregated but aggregation and density appeared not to be correlated. In line with the core-satellite hypothesis bimodal species rank order distributions (temporal and in relation to density) with a high number of rare species were found and patch density was correlated with number of patches occupied. Relative abundance distributions were fitted by Zipf-Mandelbrot but not by log-normal or log-series models.
