Why is it that people can end up interpreting what is being said to them in such different ways? A lot depends on whether they happen to be in a good or bad mood.
A total of 15 isolates of B. tulipae collected from home grown tulips without chemical protection and two commercial tulip plantations were examined by RAPD fingerprint analysis. The first tulip plantation was protected by bulb treatment and foliage spraying with fungicides in the growing period and the second plantation – only by the application of fungicides in the growing period. In the previous study, a set of isolates obtained from a plantation with an extensive use of fungicides demonstrated a higher pathogenicity level measured by the inhibition of plant growth, the percentage of bulb and root necrosis in flower pot tests on forced tulips, and by the necrosis size in tests on leaf disks. The relationships between the groups and among isolates were determined by cluster analysis of mean character differences using UPGMA and NJ methods. Similarity index values ranged from 0.872 to 1; on average, the index value was 0.933. A mean similarity of genotypes indicated the highest genotype uniformity of isolates obtained from a plantation with the extensive use of fungicides. 3 groups of clusters, could be observed in the obtained dendrograms. The first cluster contains exclusively genotypes of isolates obtained from a plantation with an extensive use of fungicides, the second one only genotypes of isolates obtained from a plantation protected only by the application of fungicides in the growing period and the third – one genotype of previous group of isolates and four genotypes of isolates obtained from home grown tulips without chemical protection. The most distinct differentiation between the groups of isolates was observed by the amplification using primers G4, H20 and J13. The results of this study revealed genetic similarity between isolates which were obtained from chemically protected plantations and demonstrated a higher degree of pathogenicity in comparison to the isolates which were obtained from unprotected plants and showed a lower degree of pathogenicity.
We can hardly imagine the Earth without majestic trees and omnipresent shrubs. But not all of us realize that these plants owe their success to ubiquitous yet often unnoticeable fungi. What links these two types of organisms together is life-giving water. It is the reason why trees and fungi have been inseparable for hundreds of millions of years. How do droughts affect trees and their evolutionarily ancient symbiosis with fungi?
In studying contemporary transformations of social relations and family life, researchers and social theorists have been focused on the increased diversity of forms of bonding, coupling and other interpersonal connections. When single people are discussed, either it is to emphasize the disintegration of their ties and the crisis of the family, or their single life is considered as an identity choice. The aim of this text is to look at the experience of singleness not by choice among contemporary corporate employees in Poland and to try to set this experience against the background of a broader social reality, especially the reality of professional work. The text also examines the relationship between relational forms (including being single) and the social system in late capitalism. The experiences of people who are not single by choice are discussed and contrasting variants for people whose single situation is associated with low interpersonal skills and for those with an interactional proficiency are distinguished. In the conclusion, the authors are looking for patterns of connection between being unwillingly single and operating on the late capitalist labour market.
We provide a detailed analysis of a unifying theoretical framework forinnovation and corporate dynamics that encompasses the Gibrat’s Law of Proportionate Effect and the Simon growth process as particular instances. The predictions of the model are derived in terms of (i) firm size distribution, (ii) the distribution of firm growth rates, and (iii-iv) the relationships between firm size and the mean and variance of firm growth rates. We test the model against data from the worldwide pharmaceutical industry and find its predictions tobe in good agreement with empirical evidence on all four dimensions. Our unifying stochastic framework can also be used to describe corporate dynamics in different industries and as a benchmark for discriminating among alternative data generating processes.
Gaston Milhaud (1858–1918) was a French modern philosopher, who, having started from mathematics, came to philosophy (especially epistemology) and history of science. His works on the history of science were devoted to Greek science and modern science. Milhaud in his papers claimed that important concepts and principles of science (in different disciplines) result from decisions that simultaneously transcend both experience and logic. He emphasized the role of free creation and activity of the mind. The author discusses central problems of Milhaud’s thought, especially the problem of the relationship between science and philosophy.
This essay is a new reading of Jan Barszczewski's collection of stories Szlachcic Zawalnia czyli Białoruś w fantastycznych opowiadaniach [Nobleman Zawalnia, or Belarus in Fantastic Stories of the Imagination] in the context of the 19th-century reception of the Arabian Nights and, more importantly, as an example of a genre which combines the oral and the literary traditions to express the identity-fostering experience of living at a time of upheaval and epochal change. This approach has little interest in revisiting the connections between Barszczewski's tales and Belorussian folklore. Instead, it places his stories in their direct historical context, i.e. a series of famines in Belarus the first decades of the 19th century, and the significance of 1816, the year in which the action of the stories is set. It is no coincidence that it was also the Year without a Summer, a catastrophic global climate anomaly, which made a great impact on the Romantic imagination.
