Introduction to Sources of German law: German Collections at the Institute of Advanced Legal Studies

This article, written by Katherine Read, gives an introduction to printed and electronic German legal resources available at the Library of the Institute of Advanced Legal Studies and on the Web. Particular attention is given to English language sources where available

Empirical study of cartograms

We report on an empirical study investigating the effectiveness and efficiency of spatial inference making with contiguous (value-by-area) cartograms, compared to informational equivalent choropleth maps, combined with graduated circles. We find significant differences in people's inference-making performance dependent on the map type. Overall, results suggest that the choropleth map with graduated circles is more effective and more efficient than the cartogram for the analysis of population census data. However, map effectiveness and efficiency also significantly depends on the inference task complexity, and more surprisingly, on the shape characteristics of the depicted enumeration units. For simple tasks, cartograms seem as effective and efficient as the more traditional mapping method. For complex inference questions, inference performance with cartograms is significantly dependent on whether regular or irregular zones are distorted. As we know still very little about the perception and cognition of cartograms, we hope to shed new light for this intriguing mapping method with this empirical study

Studies on the Thermolysis of Ether-Stabilized Lu(CH2SiMe3)3. Molecular Structure of Lu(CH2SiMe3)3(THF)(diglyme)

Lu(CH2SiMe3)3(THF)2 (2) decomposes slowly at room temperature with formation of Me4Si. In order to understand the mechanism of this elimination process, Lu(CH2SiMe3)3([D8]-THF)2 (1), Lu(CH2SiMe3)3(THF)(DME) (3), and Lu(CH2SiMe3)3(THF)(diglyme) (4) were prepared. The results of 1H NMR spectroscopic studies of the decomposition in solution exclude an α- as well as a β -H elimination mechanism and point towards a γ -H elimination. The molecular structure of 4 has been determined by single crystal X-ray diffraction.DFG, GRK 352, Synthetische, mechanistische und reaktionstechnische Aspekte von MetallkatalysatorenDFG, SPP 1166, Lanthanoidspezifische Funktionalitäten in Molekül und Materia

A Checklist of the Vascular Plants of the \u27\u27Whiting Triangle\u27\u27 in Central Wisconsin

The vascular flora of the \u27\u27Whiting Triangle\u27\u27 - a 30 acre (12 ha) area of semi-wild land within the Stevens Point, Wisconsin urban area has been observed and collected since 1964. Four hundred seventeen taxa have been collected at this site, including typical species of central Wisconsin as well as rare or otherwise notable taxa for the state. A checklist of the flora is presented

Cauli: a mouse strain with an Ift140 mutation that results in a skeletal ciliopathy modelling jeune syndrome

Cilia are architecturally complex organelles that protrude from the cell membrane and have signalling, sensory and motility functions that are central to normal tissue development and homeostasis. There are two broad categories of cilia; motile and non-motile, or primary, cilia. The central role of primary cilia in health and disease has become prominent in the past decade with the recognition of a number of human syndromes that result from defects in the formation or function of primary cilia. This rapidly growing class of conditions, now known as ciliopathies, impact the development of a diverse range of tissues including the neural axis, craniofacial structures, skeleton, kidneys, eyes and lungs. The broad impact of cilia dysfunction on development reflects the pivotal position of the primary cilia within a signalling nexus involving a growing number of growth factor systems including Hedgehog, Pdgf, Fgf, Hippo, Notch and both canonical Wnt and planar cell polarity. We have identified a novel ENU mutant allele of Ift140, which causes a mid-gestation embryonic lethal phenotype in homozygous mutant mice. Mutant embryos exhibit a range of phenotypes including exencephaly and spina bifida, craniofacial dysmorphism, digit anomalies, cardiac anomalies and somite patterning defects. A number of these phenotypes can be attributed to alterations in Hedgehog signalling, although additional signalling systems are also likely to be involved. We also report the identification of a homozygous recessive mutation in IFT140 in a Jeune syndrome patient. This ENU-induced Jeune syndrome model will be useful in delineating the origins of dysmorphology in human ciliopathies

Empirische Untersuchung Tiefenstruktur-orientierter Planung im Fachpraktikum Physik: zur Rolle kommunikativer Impulse in der didaktischen Strukturierung

Inwiefern Studierende im Fachpraktikum Physik ihre Sensibilität bzgl. sprachlicher Kommunikation weiterentwickeln und wie sie mit sprachlichen Mitteln Ziel- und Prozessklarheit in ihrem Unterricht herstellen, wird in dieser empirischen Studie untersucht. Zum Einsatz kommen Fragebögen für 16 Studierenden als auch Interviews, Lerntagebücher sowie begleitende audiogestützte Beobachtungen im Unterricht mit acht der Studierenden. Im Begleitseminar zum Praktikum sollen sich die Studierenden ein Planungsmodell aneignen, das die Sicht- und Tiefenstruktur explizit voneinander unterscheidet, um sie dann in systematischer Weise aufeinander beziehen zu können. Die Daten erlauben, die Einschätzungen der Studierenden und ihrer Kompetenzentwicklung in der komplexen Situation des Praktikums zu modellieren: Inwieweit gelingt es ihnen, kommunikative Impulse in ihren Planungen zu formulieren, diese mit der fachlichen Struktur des Unterrichts zu verknüpfen und ihre Planung im Unterricht umzusetzen
