Biocomputing in a Nutshell
No full textThis website, written by Ulf Reimer and Georg Fuellen and presented by the University of Bielefeld in Germany, offers a broad introduction to bioinformatics. Beginning with the development of modern molecular biology, and then discussing the huge amount of data and how to analyze it, the article concludes that an interdisciplinary approach to biocomputing is advantageous because it allows research to "transcend the limits of reductionism; from the vast quantities of bytes and pieces, the contours of complex structures and relationships might emerge from the genetic alphabet soup as life itself once emerged from the primordial soup."

No full textThis is the fifth of a series of reports from the research program Youth Culture in Sweden, FUS. In the first article, Johan Fornäs discusses how concepts such as sphere, space, field and institution may be used in order to understand processes of power and resistance. Specific attention is given to thinkers such as Habermas, Foucalt, Bourdieu and Willis, but Fornäs also discusses more recent feminist theory as well as theories of ethnicity and identity. In the second article, Magdalena Czaplicka analyses young people’s trajectories through the educational system and into the labour market. She focuses on how the choices and opportunities given to youth are structured by factors such as class and gender. Anders Löfgren applies the concepts of life project and arena on identity formation. Through the use of ideas from social theory and cultural geography, he argues that life projects in late modernity, although still grounded in local environments, are becoming more and more globalised. Mats Lieberg discusses the importance of public spaces for young people’s entrances into adulthood. He also analyses how young people make use of public spaces in their everyday life practices. Bo Reimer discusses the role of the mass media for young people in everyday life. He focuses on how the electronic media have changed social behaviour, and on how young people act – and react – in an environment saturated by the mass media. Ulf Boëthius discusses youth, popular culture and media through the use of the concept of moral panics. In an historical overview, he shows how the concept may be applied to a number of heated debates and conflicts centrered around youth and popular culture that have taken place during the latest century. He also discusses whether such panics still are possible in late modernity. Finally, Thomas Ziehe analyses the effects of modernization and rationalization in the spheres of education and science. He specifically focuses on the self-reflexivity which he argues cannot be avoided anywhere in late modernity

ULF vlny/fluktuace ve forešoku: Statistický přístup
No full textTitle: ULF waves/fluctuations in the foreshock: Statistical approach Author: Anna Mita Department: Department of Surface and Plasma Science Supervisor: Prof. RNDr. Jana Šafránková, DrSc., Department of Surface and Plasma Science Abstract: The thesis deals with ultra-low frequency (ULF) wave activity in the terrestrial foreshock, a turbulent region upstream of the bow shock that plays a crucial role in the interaction of the solar wind with the magnetosphere. In the thesis, we analyze some aspects of the behavior of ULF waves/fluctuations of the magnetic field, using a statistical point of view. We focused (i) on the boundary between the pure solar wind and wave activity region represented by enhanced ULF fluctuations, and on the changes of the boundary position with solar wind conditions and interplanetary magnetic field orientation; and (ii) on growth rates of foreshock ULF fluctuations at different distances from the bow shock with a special highlight on a region close to the Moon. In both statistical studies, we use THEMIS/ARTEMIS data and describe the behavior of fluctuations by the standard deviations in the ULF range of 0.0017-0.17 Hz. We present a novel coordinate system, determine so-called "foreshock ULF boundary" and report its realistic shape that is consistent with the theory of the foreshock...Název práce: ULF vlny/fluktuace ve forešoku: Statistický přístup Autor: Anna Mita Katedra: Katedra fyziky povrchů a plazmatu Vedoucí disertační práce: Prof. RNDr. Jana Šafránková, DrSc., Katedra fyziky povrchů a plazmatu Abstrakt: Předložená práce se zabývá ULF (Ultra Low Frequency) fluktuacemi v turbulentní oblasti před rázovou vlnou (forešok), která hraje klíčovou roli v interakci slunečního větru s magnetosférou Země. V práci analyzujeme některé aspekty chování ULF vln/fluktuací magnetického pole s využitím statistického zpracování dat naměřených dvěma družicemi projektu THEMIS/ARTEMIS. Zaměřili jsme se (i) na hranici mezi neporušeným slunečním větrem a oblastí charakterizovanou vysokými ULF fluktuacemi a na změny polohy této hranice v závislosti na podmínkách ve slunečním větru a na orientaci meziplanetárního magnetického pole; a (ii) na rychlost růstu nebo tlumení ULF vln/fluktuací v různých vzdálenostech od rázové vlny se zvláštním zřetelem na oblast blízko Měsíce. Ve statistických studiích popisujeme chování fluktuací pomocí směrodatných odchylek v rozsahu 0,0017-0,17 Hz. V práci představujeme nový souřadnicový systém umožňující určit tzv. "foreshock ULF boundary", diskutujeme nalezený tvar a ukazujeme, že je v souladu s teorií formování forešoku. Ve druhé studii se soustřeďujeme na růst (případně...Katedra fyziky povrchů a plazmatuDepartment of Surface and Plasma ScienceFaculty of Mathematics and PhysicsMatematicko-fyzikální fakult
