Two urban stress tolerant Tilia clones were selected by the Department of Floriculture and Dendrology. The mother trees of the Observed clones were found in an alley of linden trees, settled on a traffic island of a busy two-lane road. Tilia hybrid 'Saint Stephen' has a beautiful cone-shaped crown, the leaves are bright green and they keep their green colour for much longer time than the leaves on the other trees in the alley. In the nursery the Tilia hybrid 'Saint Stephen' was budded on T. cordata, T. platyphyllos and T. argentea and it had good compatibility with every rootstock. The average height of the one year old buddings was 200 cm and the buddings kept their good growing capacity in the following years as well. They had an outstanding growing capability comparing with the other Tilia cultivars. Tilia platyphyllos 'K3' clone has similar cone-shaped crown. The growing vigor and urban stress tolerance seems to be better than Tilia hybrid 'Saint Stephen'.

The United States is in a bind. On the one hand, we need millions of additional citizens with at least one year of successful post-secondary experience to adapt to the knowledge economy. Both the Gates and Lumina Foundations, and our President, have championed this goal in different ways. On the other hand, we have a post-secondary system that is trapped between rising costs and stagnant effectiveness, seemingly unable to respond effectively to this challenge. This paper analyzes several aspects of this problem, describes changes in the society that create the basis for solutions, and offers several examples from Kaplan University of emerging practice that suggests what good practice might look like in a world where quality-assured mass higher education is the norm.

In Algeria, the problems of erosion and sediment transport are critical, since they have the most dramatic consequences of the degradation of agricultural soils on the one hand and the siltation of the dam on the other .The sediment transport in the Algerian basins is very important especially during the periods of floods, It is in this sense that this study, which consists of estimating the sediment transport in suspension and determining the models of relation linking the liquid discharge and the sediment discharge in order to estimate the solid transport in the absence of suspended sediments concentration data at the Sidi Akkacha station at the outlet of the basin of Oued Allala which is subject to a high water erosion, it degrades from one year to the other under the effect of this phenomenon especially during the floods which drain high amounts of fine particles exceeding in general, the concentration of 150 g/l, the results obtained from the application of the models are very encouraging since the correlation between liquid and solid discharge exceeds 80 %.

We tested the hypothesis that pigeons could use a cognitively efficient coding strategy by training them on a conditional discrimination (delayed symbolic matching) in which one alternative was correct following the presentation of one sample (one-to-one), whereas the other alternative was correct following the presentation of any one of four other samples (many-to-one). When retention intervals of different durations were inserted between the offset of the sample and the onset of the choice stimuli, divergent retention functions were found. With increasing retention interval, matching accuracy on trials involving any of the many-to-one samples was increasingly better than matching accuracy on trials involving the one-to-one sample. Furthermore, following this test, pigeons treated a novel sample as if it had been one of the many-to-one samples. The data suggest that rather than learning each of the five sample-comparison associations independently, the pigeons developed a cognitively efficient single-code/default coding strategy.

Migration and health are intimately connected. It is known that migrants tend to be healthier than non-migrants. However, the mechanisms for this association are elusive. On the one hand, the costs of migration are lower for healthier people, thereby making it easier for the healthy to migrate. Empirical evidence from a variety of contexts shows that the pre-migration health of migrants is better than it is for non-migrants, indicating that there is positive health-based selection in migration. On the other hand, locations can be viewed as a bundle of traits including but not limited to environmental conditions, healthcare quality, and violence. Each of these can impact health. Evidence shows that moving from locations with high mortality to low mortality can reduce mortality risks. Consistent with this, migration can increase mortality risk if it leads to greater exposure to risk factors for disease. The health benefits enjoyed by migrants can also be found in their children. However, these advantages erode with successive generations.

AbstractThe global economic-financial downturn has given new impetus to a re-examination of Rosa Luxemburg’s writings on capitalist accumulation and economic crisis, which pinpointed the central contradiction of capitalism in its drive for global expansion. In this article I critically engage Luxemburg’s theory of capital accumulation and crisis by evaluating it in comparison with the central categories of Volumes One and Two of Marx’sCapitalon the one hand, and the quest for an alternative to capitalism in the twenty-first century on the other. I argue that Marx’s procedure in Volume Two ofCapital, in which he abstracts from realization crises and foreign trade in order to discern the “law of motion” of capital freed from secondary and tertiary considerations, captures the internal dynamic of capitalist development and crises far better than its Keynesian and neo-Keynesian alternatives.

Robert Johnson (1911–1938) is the most venerated of all pre-war blues musicians; the veneration borders on hagiography. Recently published revisionist literature has constructed a sociologically realistic portrayal of a professional musician working among other musicians for a contemporary audience in a specific historical context. This has left unexplained, however, the veneration granted to his music by the audience for his records from the 1960s to today. This paper presents the case that these two bodies of fact can be connected and the one serve as an explanation for the other. As Robert Johnson learned his craft from records and radio, and polished his songs to be recorded, he effectively developed a ‘for-the-record’ aesthetic that made his music sound different to that of his Delta contemporaries and many others who used musical techniques honed in performance for an audience. Decades later, when a ‘for-the-record’ aesthetic was the taken-for-granted standard in popular musical culture, Robert Johnson's records sounded better than those of his contemporaries, and the audience from the 1960s to today has had a reason to think that he and his music were special.

AbstractThe survival of Oryzaephilus surinamensis (L.) and Sitophilus granarius (L.) adults at the surface and centre of two 40-tonne bins of wheat, each aerated at about 10 m3/h per tonne was studied in separate experiments over three successive years. In one bin, fan operation was controlled manually, but in the other an automatic differential thermostat was used. This switched on the fan when the centre of the bin was 2°C warmer than the ambient. O. surinamensis always survived better than S. granarius in the same bin and position. Both species survived better at the surface of each bin than at the centre, and both died quicker at the centre of the bin with aeration controlled with a differential thermostat, where the grain temperature was usually less than 4°C, than in the bin with aeration regulated manually, which was mainly above 6°C. However, there was no difference between bins in the survival of either species at the surface. S. granarius always died out in both positions in both bins, but O. surinamensis always survived at the surface of both bins, and in one year it survived at the centre of the bin with aeration controlled manually.

The Fundamental Concern in Translation Theory, from Saint Jerome to the Present, has Been the Relation Between a Text and its version in another language. This relation is often conceived in the Platonic terms of original and copy: the original is viewed as sacrosanct (especially when it is a sacred text but also when it is not), while the translation is seen, at best, as imperfect and deficient and, at worst, as an adulteration, a profanation, and a betrayal that is captured in the Italian phrase traduttore traditore. Conversely, that relation has on occasion also been inverted in claims that the translation can be superior to the original—for example, Jorge Luis Borges's famous declaration that “the original is unfaithful to the translation” (239) or, less radically, Gabriel García Márquez's reported remark that Gregory Rabassa's translation of One Hundred Years of Solitude is better than the Spanish original (Rabassa 43). At other times, the relation between original and translation is seen as antagonistic, the one trying to displace the other, or as its heir and only chance of survival. In this view, the original is condemned to death and oblivion because it is written in a dead language, a rival language, or a geopolitically weak language. Think of the phenomenon that Abdelfattah Kilito cites of some classical Arabic texts—such as al-Harīrī‘s Maqāmāt (“Assemblies”), written at the height of Arab civilization's power in the twelfth century—which seem to have been composed in such a way as to render their translation impossible (17-18). By contrast, notes Kilito, some contemporary Arab novelists seem to write with their translators in mind, avoiding difficult language and obscure cultural expressions that may reduce their works’ chances of being translated into English or French, the gateway to international success (19n7).

The One

There are two factors affecting the diet of urban Natives: on the one hand there is the expansive influence of assimilation to and adoption of European food habits, and on the other hand there is active a restrictive influence in the shape of poverty. The urban Native, through his close contact with European culture which residence in an urban environment inevitably entails, has been introduced to an extraordinarily wide range of new foodstuffs and new ways of preparing food. Consequently the range of his food desires has been much increased. But his desires are not allowed free play among this new and wide selection. The factor which narrows down his choice and curbs his desire is his poverty. The urban Native eats according to the capacity of his pocket and his food is usually the first item of expenditure which is marked out for especial economy.

The City

An analysis is provided of the spatial-functional structure of the area of Główna, Zawady, Gdyńska and Bałtycka streets in Poznań. This region of the city is unique. On the one hand, it contains particularly valuable architectural forms, often of historical and cultural merit, and several interesting natural-landscape features passing into historical structural wedges of urban greenery. On the other hand, however, there are also storehouses as well as manufacturing and service shops there, often side by side with residential housing. The area displays a mix of functions and building forms, a deteriorating state of repair of the buildings, a vandalised urban environment, and advancing processes of ageing and depreciation. The paper is concluded with a presentation of the measures devised to transform the area that have been outlined in the Study of determinants and directions of the spatial development of the city of Poznań and the authors’ own observations.
