From Admiration to Confrontation: Gunter Grass and the United States
No full textGunter Grass is. without doubt, the best known representative of postwar and contemporary German literature in the United States. A few random samples culled from reviews of Grass\u27s work in this country may suffice to illustrate this point. In 1964, on occasion of the English translation of Hundejahre (Dog Years), Newsweek wrote: Gunter Grass today is acknowledged as the author who put postwar German literature back in the world market. He is fast becoming a director of much of his country\u27s creative movement, a keeper of old myths and new methods. The Tin Drum, the novel that so far has determined Grass\u27s reception in this country-the voluminous and challenging The Flounder notwithstanding-was even credited with initiating the rebirth of German letters. The recent film version of The Tin Drum contributed to a revival of interest in the novel; in 1982 the novelist John Irving stated: Die Blechtrommel … has not been surpassed, it is the greatest novel by a living author.\u27\u27 Irving continued in his praise of the author of The Tin Drum by claiming that you can\u27t be well-read today if you haven\u27t read him. Gunter Grass is simply the most original and versatile writer alive. Although such lavish critical endorsement is not to be encountered in all quarters, at least one other segment of the reading public, the professional intermediaries of German literature, that is, the professors and teachers of German, seem to agree with Irving. In a literary opinion poll conducted by the Goethe Institute in Boston. Massachusetts, The Tin Drum ranked first among the professors\u27 favorite works of postwar German literature. Curiously, The Flounder attained second place-ahead of such redoubtable works as Thomas Mann\u27s Doctor Faustus, Heinrich Boll\u27s Group Portrait with Lady, and Max Frisch\u27s Homo Faber
Robust cluster analysis and variable selection
No full textClustering remains a vibrant area of research in statistics. Although there are many books on this topic, there are relatively few that are well founded in the theoretical aspects. In Robust Cluster Analysis and Variable Selection, Gunter Ritter presents an overview of the theory and applications of probabilistic clustering and variable selection, synthesizing the key research results of the last 50 years. The author focuses on the robust clustering methods he found to be the most useful on simulated data and real-time applications. The book provides clear guidance for the varying needs of bo

A Mythic Journey: Gunter Grass\u27s Tin Drum
No full textAlthough The Tin Drum has often been called one of the great novels of the 20th century, most critics have been baffled in attempting to draw its apparent chaos into a single literary framework. Here is the full-length study to penetrate the brilliance of Gunter Grass’s style and uncover the novel’s mythopoetic core. In A Mythic Journey: Gunter Grass\u27s Tin Drum, author Edward Diller convincingly demonstrates the still valid relationship between modern and classical literary criticism. By reading The Tin Drum as both modern myth and historical epic, he provides a profound and sensitive interpretation of one of the masterpieces of 20th century literature.
Edward Diller is a professor of German at the University of Oregon.https://uknowledge.uky.edu/upk_german_literature/1001/thumbnail.jp
Wärmeleitfähigkeiten anisotroper Gesteine
No full textCa. 70 — mit wenigen Ausnahmen orientiert im Gelände bzw. unter Tage entnommene — Gesteinsproben wurden bei einer Temperatur von ca. 94° C und Atmosphärendruck auf ihre Wärmeleitfähigkeiten in verschiedenen Richtungen untersucht. Insgesamt wurden einschließlich der Wiederholungsmessungen ca. 500 Einzelmessungen der Wärmeleitfähigkeit durchgeführt. Bei den untersuchten Proben handelt es sich zum großen Teil um Tonschiefer aus dem Rheinischen Schiefergebirge und dem Harz, zum kleineren Teil um Kalksteine aus dem Rheinischen Schiefergebirge, Metamorphite aus den Ostalpen und anderen Gebieten sowie um einige Magmatite.
Bei den meisten untersuchten Proben, insbesondere denen mit schon äußerlich erkennbaren Planar- und Lineartexturen, sind die Wärmeleitfähigkeiten streng richtungsabhängig; diese Proben sind bezüglich der Wärmeleitfähigkeit (und anderer gesteinsphysikalischer Eigenschaften) anisotrop. Die Meßergebnisse werden in den Tabellen 2 bis 5 vorgestellt.The heat conductivities of some 70 oriented rock specimens taken from the field or subsurface were determined in various directions at about 94° C and atmospheric pressure. Some 500 individual measurements, duplicate measurements included, were carried out.
The majority of the tested samples are slates from the Rheinische Schiefergebirge and the Harz (“Rhenoherzynikum”), a minor portion is made up of limestones from the Rheinische Schiefergebirge, metamorphic rocks from the central Eastern Alps and some other areas, and only some magmatic rocks were tested for comparison. The results of the heat conductivity measurements are presented in the tables 2–5.
In most of the rocks investigated, especially in those showing planar and linear textures at the mesoscale, the heat conductivity is strongly controlled by the direction of measurement. These rocks are anisotropic with respect to the heat conductivity (and to other physical rock properties as well).
The measurements of the heat conductivity in slates from the Rheinische Schiefergebirge showed considerable differences in different directions of the rock samples. In those slates, containing a transverse (“slaty”) cleavage (s1) besides the bedding planes (ss) (the typical roofing slates, e g.), the plane of the slaty cleavage turns out to be the best heat “insulator”, i. e., the direction of the least heat conductivity of the whole rock (k33) is oriented normally to s1 The direction of the greatest heat conductivity (k11 of these rocks lies within the plane of s1 and parallel to the intersection line of ss and s1, or parallel to the “Faser” (“longrain”), a lineation down dip of the slaty cleavage planes, only in some regionally restricted areas. The direction of the mean conductivity (k22) is oriented normally to k11 in the plane of s1. The anisotropy of heat conductivity in these slates (as well as in the mica schists and gneisses investigated) shows a orthorhombic symmetry. The tensor of the heat conductivity for these rocks, referred to the main axes, has the form
In other “slates”, or better “shales” in the cases concerned, from the upper part of the Rhenohercynian sedimentary column, lacking any transverse cleavage at the mesoscale and rearrangements and new crystallization of the phyllosilicate minerals at the microscale, the bedding plane (ss) turns out to be the best heat “insulator”. Consequently, the direction of least heat conductivity (k33) in these rocks is normal to the bedding plane (ss). Within the bedding plane there is no preferred direction of heat conductivity (k11 = k22 > k33). Both slate types differing with respect to the anisotropy of heat conductivity with k33 ⊥ s1 and k33 ⊥ ss, resp., are linked by transitional stages.
The results of heat conductivity measurements in slates from different tectonic frameworks (tectonic “environments”) of the Rhenoherzynikum presented here, reflect — in an indirect way — the various finite stages of the progressive fabric development within a relatively “shallow” orogen such as the Rheinische Schiefergebirge and the Harz, according to the author (Langheinrich 1964, 1976, 1978).
Measurements of the heat conductivity of limestones from the Rheinische Schiefergebirge showing marked evidence of finite internal tectonic deformation demonstrated that these rocks are isotropic with regard to heat conductivity, presumably as a result of posttectonic annealing recrystallization of the rock forming calcite.
Within the mica-schists and gneisses investigated the heat conductivity is always at a minimum normal to the s-planes (foliation) of these rocks, and at a maximum within the s-planes, mostly parallel to a lineation at mesoscale. Within this group of rocks the highest (k11) and lowest heat conductivity (k33) can differ by a factor of nearly 3 (table 4).
All specimens of magmatites, only measured for comparison, showed near-perfect isotropy of heat conductivity.
The whole-rock anisotropy of heat conductivity — considered under the conditions of experiment — is controlled by a number of factors. But the essential factors controlling this strong whole-rock anisotropy of the slates, mica-schists, and gneisses are the presence in considerable amounts of rock forming minerals with high individual anisotropies of heat conductivity, and the statistically preferred orientation of these minerals.
The phyllosilicate minerals illite/muscovite with an “anisotropy factor” (k11/k33) of about 6 and chlorite (with a presumably similar “anisotrop factor”) play a major part. Quartz which shows some preferred crystal lattice orientation in some cases only plays a subordinate role with respect to the whole-rock anisotropy of heat conductivity. The “anisotropy factor” of quartz is about 1.7 (at room temperature).
The statistically preferred orientation of some crystal lattices of the rock forming minerals with high individual anisotropies of heat conductivity was studied for a series of representative specimens of slates using a X-ray texture goniometer. The X-ray studies revealed excellent geometric correlations between the symmetries of the X-ray textures and the anisotropy of heat conductivity.
Some 50 specimens of slates were selected for measurements of the propagation velocity of longitudinal ultrasonic pulses in various directions. Here, a perfect geometric correlation of the anisotropy of heat conductivity and the elastic anisotropy was found.
Comparisons of the degree of crystallinity of illite and the anisotropy of heat conductivity in some slate specimens revealed no clear-cut correlation of these two parameters (see table 2).
Before extending the data of heat conductivity and anisotropy of heat conductivity of rocks, determined under laboratory conditions, to “in situ” conditions a number of correction factors must be taken into account. These correction factors involve temperature conditions, the porosity of rocks, the kind of the pore fluids, the crack content (again a function of the stress conditions “in situ”), and others.Près de 70 échantillons de roches pris sur le terrain ou en subsurface, et orientés sauf quelques exceptions, ont été examinés en vue de leurs conductibilités thermiques dans des directions différentes à une température de 94° C et à pression atmosphérique. En tout 500 mesures individuelles de conductibilité thermique ont été exécutées, y compris les mesures doubles. Les échantillons examinés sont pour la plupart des schistes argileux du Massif Schisteux Rhénan et du Harz, le reste provient de calcaires du Massif Schisteux Rhénan, de métamorphites des Alpes orientales et d'autres régions, ainsi que quelques magmatites.
Les conductibilités thermiques de la plupart des échantillons examinés, surtout de ceux qui montrent des textures planaires et linéaires déjà reconnaissables à l'extérieur, dépendent strictement de la direction; ces roches sont anisotropes du point de vue de la conductibilité thermique (ainsi que d'autres caractères physiques de roches).

Elevations, icons and lines: The city abstracted through its skylines
No full textThis working paper explores the potential and the limitations of understanding certain social and
spatial relationships through a study of the city from a distance. In particular, the author analyses the notion
of skylines and their relationships to individual tall buildings and the ‘whole’ city, focussing on the City
of London as viewed across the River Thames from the South Bank. This paper is related to the author's broader PhD research that involves an exploration of the nature, production and significance of skylines with a focus on professional skyline discourses relating to the City of London
From ‘Jurassic Management’ to a flourishing revival of critical studies of educational leadership : some reflections on the contribution of Helen Gunter and some encounters with her along the way
No full textThis chapter deals with the seminal contribution of Helen Gunter to the revival of critical educational leadership studies. It traces the way in which Helen’s defining work Rethinking Education: The Consequences of Jurassic Management (London: Cassell, 1997) has profoundly influenced and shaped the field since she first published it. At a personal level, I show how this work by Helen gave me the courage and inspiration to continue beyond the point at which I had given up on the field of educational leadership. I trace the central motifs of critical educational leadership that have since come to define Helen Gunter’s extensive field of critical scholarship, and that in no small measure led me into my more recent pursuits of what I have called ‘bullshit leadership’-what passes as the mainstream field. I am enormously grateful to Helen for her enthusiasm, perspicacity, and above all her warmth as a scholar and close friend. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2023
<em>Pasos perdidos y pesados</em>, cronache di passaggi di frontiera nell’opera di Gunter Silva Passuni
No full textThis article aims to include the collection of short stories Cronicas de Londres (2012) and the novel Pasos pesados (2016) by the Peruvian writer Gunter Silva Passuni in the Latin American migration literature paradigm. The author builds a narrative path, with autobiographical reflections, which focus on the complexity of migrant subjectivity and his double epistemological status: he is both emigrant and immigrant, following the pattern of “double absence” theorized by Sayad. Therefore, the literary experience becomes a possibility of cultural rehabilitation in a subject in transit, marked by a non-dialectic synthesis of his identity produced by the arguably compulsory crossing of the border
