  3. Der Briefwechsel zwischen Alexander von Humboldt und Karl Ernst von Baer

    2012-10-01

    Full Text Available Zusammenfassung Der kurze, nicht vollständig erhaltene Briefwechsel zwischen Alexander von Humboldt und Karl Ernst von Baer behandelt sehr verschiedene Themen: Politik, Kriegsgefahr, den Wissenschaftsbetrieb, Auszeichnungen und Tagungen, Embryologie und Cholera. Gemeinsam mit Briefen und Reden ergibt sich dabei ein differenziertes Bild der Beurteilung der beiden Wissenschaftler durch den jeweils anderen. Während Baer sich als Bewunderer Humboldts erweist, erscheint umgekehrt Humboldts Einschätzung Baers als ambivalent. Abstract The short, not completely preserved correspondence between Alexander von Humboldt and Karl Ernst von Baer deals with a wide range of subjects: politics and the danger of war, academic activities, scientific awards and conferences, aspects of embryology and the cholera. Letters to third persons and speeches, together with the correspondence between Humboldt and Baer show a differentiated pattern of mutual appraisal: While Baer always remained an admirer of the elder naturalist, Humboldt’s estimation was characterized by ambivalence.

  4. The origin of art according to Karl von den Steinen

    2015-06-01

    Full Text Available Based on a study of the custom, adopted by ethnologists in the early 20th century, of asking Amerindians of Lowland South America to do drawings in pencil in their notebooks, I explore three forgotten fragments of the history of thinking: the intense debates on the origin of ornaments, opposing an evolutionist and a materialist approach at the end of the 19th century; the theories on the origin of figuration, which I show date back to the important work of Karl von den Steinen regarding the populations of central Brazil; and the publications of ethnologists’ portraits drawn by Indians of the lowlands of South America, a little-known tradition of reverse anthropology serving as a counterpoint to the study of the reception of Amerindian art in Western ethnological literature.

  8. Karl ernst von Baer's 'Uber Entwickelungsgeschichte der Thiere II' and its unpublished drawings.

    Science.gov (United States)

    Tammiksaar, Erki; Brauckmann, Sabine

    2004-01-01

    In 1828 Karl Ernst von Baer (1792-1876) published his seminal Uber Entwickelungsgeschichte der Thiere. Beobachtung und Reflexion. In the preface he announced that a second volume with one copper plate would be finished 'in a few weeks'. However, it took nine years until the unfinished second volume was released, with four copperplates. In his 'Autobiography', von Baer did not clarify the reasons why he did not finish his research program of comparative embryology. The paper attempts to elucidate them, furnished by archival documents and von Baer's unpublished embryological drawings. Our sketch of a few figures will show that (1) von Baer searched for 'analogies' (homologies) as a unifying principle and (2) explained the mechanisms of embryogenesis by physiological reasoning (electromagnetism). The main objective is to show that technical problems in illustrating and conceptual difficulties impeded von Baer's ambitious research program.

    2008-12-15

    In his postdoctoral thesis Karl Gertis described the basic principles of the function and the geometric boundary conditions for the construction of ventilated external walls. The proposed revision of DIN 18516-1:2008-09 will again based on the fundamental results of his work. Meanwhile, further work has been carried out on various aspects, including the work by Janser and Marquardt on wind load assumptions and the corrosion-inhibiting effect of ventilated external walls. Ventilated external facings can be retrofitted to damaged walls in large-panel buildings to improve thermal insulation, as a remedial measure for joint defects, and in order to improve corrosion protection. This paper discusses the physical mechanisms relating to wind load reduction and corrosion protection. (Abstract Copyright [2008], Wiley Periodicals, Inc.) [German] Die grundlegende Arbeit ueber die Wirkungsweise und die geometrischen Randbedingungen bei der Konstruktion hinterluefteter Aussenwandkonstruktionen hat Karl Gertis mit seiner Habilitationsschrift verfasst. Auch in der geplanten Neufassung von DIN 18516-1:2008-09 wird auf die grundlegenden Ergebnisse seiner Arbeit unveraendert zugegriffen werden. Weiterfuehrende Arbeiten wurden unter anderem ueber die anzusetzenden Windlastannahmen und die korrosionshemmende Wirkung hinterluefteter Aussenwaende von Janser und Marquardt durchgefuehrt. Durch die nachtraegliche Montage von hinterluefteten Aussenwandkonstruktionen auf die geschaedigten Waende des Grosstafelbaus kann sowohl die Waermedaemmung verbessert werden als auch eine Sanierung der Fugen erfolgen; insbesondere wird aber durch das Aufbringen hinterluefteter Aussenwandkonstruktionen der Korrosionsschutz wesentlich verbessert. Im Folgenden werden die Wirkmechanismen hinsichtlich der Reduzierung der Windlast und des Korrosionsschutzes beschrieben. (Abstract Copyright [2008], Wiley Periodicals, Inc.)

  13. [The Roots of Idiographic Paleontology: Karl Alfred von Zittel's Methodology and Conception of the Fossil Record].

    Science.gov (United States)

    Tamborini, Marco

    2015-12-01

    This paper examines Karl Alfred von Zittel’s practice in order to uncover the roots of so-called idiographic paleontology.The great American paleontologist Stephen Jay Gould (1941–2002) defined the discipline of idiographic paleontology as illustration and description of the morphological features of extinct species. However, this approach does not investigate macroevolutionary patterns and processes. On the contrary, the paleobiological revolution of the 1970s implemented an epistemic methodology that illustrates macrovelutionary patterns and laws by combining idiographic data with a nomothetic form of explanation. This article elucidates the features of the idiographic data as well as the acquired knowledge coupled with this approach. First of all, Heinrich G. Bronn’s (1800–1862) statistical method is analyzed. Zittel’s practice arose as a reaction against the approximate conclusions reached by Bronn’s quantitative approach. Second, the details of Zittel’s methodology are described in order to bring out its peculiarities.The microscope played a pivotal role in creating and forming Zittel’s morphological data. This analysis sheds new light on the reasons behind the so-called ideographic paleontology, thus revising Gould’s historical reconstruction, as well as on the notion of paleontological data. However, even though Zittel aimed at reaching precise and stable conclusions,his data cannot be used for elucidating evolutionary mechanisms: they are scientific in a purely descriptive sense, but completely useless for biological investigations. Finally, this paper examines how Zittel’s methodology affects the contemporary paleobiological enterprise and thereby reflects upon the notion of natural history.

    Full Text Available Karl Lenz und Marina Adler orientieren sich in ihrem zweibändigen Lehrbuch zur sozialwissenschaftlichen Geschlechterforschung an der etablierten Unterscheidung zwischen Makro- und Mikrosoziologie. Im ersten Band werden theoretische Perspektiven der Geschlechterforschung und unterschiedliche Zusammenhänge zu Kultur nachgezeichnet sowie zentrale Themenfelder einer Sozialstrukturanalyse der Geschlechterordnung fokussiert, nämlich Recht, Politik, Bildung und Arbeit. Im zweiten Band stehen neben der Sozialisation ausgewählte Erträge der mikrosoziologischen Geschlechterforschung im Zentrum, nämlich Körper, Sexualität, persönliche Beziehungen, Devianz und Gewalt. In dieser überfälligen, informativen, sorgfältig recherchierten, aber auch vergleichsweise traditionellen und empirisch orientierten Einführung wird die Geschlechterforschung zwar in einer breiteren Diversity-Forschung verortet, das Verhältnis von Diversität und Geschlecht leider aber nicht reflektiert.

    Full Text Available This essay attempts to analyze the anthropological and ethnographical studies realized by the German traveller and scientist Karl von den Steinen at the end of the 19th century in the region of the river Xingu in Central Brazil. First a short overview will be given of both expeditions directed by him and their scientific concerns. Then the ideological and thematical orientation of the americanism of this epoch will be contrasted with the research undertaken by Karl von den Steinen in Brazil, in order to illustrate the ways in which he worked in the tradition of his time and in which aspects he departed from this framework and effected innovations in his research. After this analysis of the contributions of Karl von den Steinen to the development of German americanism, this article focuses on the question of, to which point his studies are still relevant today and if his methodology and its results continue to be valid in our time. Finally, the relationship of his ideological orientation with those of his predecessors and his successors will be thematized in order to explore Karl von den Steinen’s influences and whom he, in turn, influenced.Este artículo analiza los estudios antropológicos llevados a cabo por el viajero y científico alemán Karl von den Steinen a finales del siglo XIX en la región del río Xingú en Brasil Central.

  9. Divining and knowing: Karl Sudhoff's historical method.

    Science.gov (United States)

    Stein, Claudia

    2013-01-01

    This article investigates the historical method of Karl Sudhoff (1853- 1938), Germany's first professor of medical history. It argues that in order to understand his ideas more fully, we need to step outside the historiography of medical history and assess his methodology in relation to the norms and ideals of German academic history writing in general. The article demonstrates that the philology-based "critical method" of Leopold von Ranke (1795-1886) was central to Sudhoff's methodological thinking. It investigates the underlying philosophical and epistemological assumptions of Ranke's method, which tend to be less appreciated than his overt empiricism and explores how Sudhoff applied these to the new professionalizing subdiscipline of the history of medicine. The article argues that Sudhoff's concerns with the methodology of history, which involved a particular conception of the relationship between the human sciences and the medical sciences, offers compelling addresses to our times.

  10. Karl Jaspers' multiperspectivalism.

    Science.gov (United States)

    Wiggins, Osborne P; Schwartz, Michael Alan

    2013-01-01

    In later editions of his General Psychopathology, Karl Jaspers prescribes many different methods and theoretical points of view for psychopathologists to utilize. Each of these perspectives on the subject matter of psychopathology, however, gives the investigator access to only one dimension of the patient's being. Hence, Jaspers insists that several different perspectives must be employed in order to avoid a one-sided and partial comprehension of the patient and his or her problem. He advocates a multiperspectival approach in psychopathology. Nevertheless, Jaspers remains aware that the patient is a unified whole. This unified whole, however, is not knowable as such, but can rather be approached only under the guidance of an 'idea' of the whole. Jaspers takes the basic notion of 'idea' (Idee) from Kant, but he modifies and uses it for his own purposes. Jaspers' multiperspectivalism may seem to invite charges of relativism because it leaves the psychopathologist to 'pick and choose' any method or theory he or she prefers. This charge is addressed by admitting that there does exist a certain relativism in Jaspers' position in that any one perspective does provide only one approach to the reality of the patient and that other equally useful perspectives could have been chosen. However, each perspective itself can be subjected to test by evidence, and in such tests, claims made from that perspective can be found to be true or false. Helen Longino's theory of scientific knowledge helps support such a thesis.

  11. Karl Popper's Quantum Ghost

    Science.gov (United States)

    Shields, William

    2004-05-01

    Karl Popper, though not trained as a physicist and embarrassed early in his career by a physics error pointed out by Einstein and Bohr, ultimately made substantial contributions to the interpretation of quantum mechanics. As was often the case, Popper initially formulated his position by criticizing the views of others - in this case Niels Bohr and Werner Heisenberg. Underlying Popper's criticism was his belief that, first, the "standard interpretation" of quantum mechanics, sometimes called the Copenhagen interpretation, abandoned scientific realism and second, the assertion that quantum theory was "complete" (an assertion rejected by Einstein among others) amounted to an unfalsifiable claim. Popper insisted that the most basic predictions of quantum mechanics should continue to be tested, with an eye towards falsification rather than mere adding of decimal places to confirmatory experiments. His persistent attacks on the Copenhagen interpretation were aimed not at the uncertainty principle itself and the formalism from which it was derived, but at the acceptance by physicists of an unclear epistemology and ontology that left critical questions unanswered. In 1999, physicists at the University of Maryland conducted a version of Popper's Experiment, re-igniting the debate over quantum predictions and the role of locality in physics.

    Full Text Available Dedicated to Karl Popper’s memory, this essay aims at following the echo of his critical rationalism and how it has been received by Mario Bunge, one of the most prominent contemporary philosopher of science – an admirer, later a critic of Popper’s social and political philosophy. The main goal of such an endeavor is to find out where could have been Popper wrong – from Bunge’s view point – and take note of the arguments of both of them, thus hoping to get closer to the truth, as Sir Karl said.

    The forced migration process of German-speaking neurologists and psychiatrists under the Nazis during the 1930s and 40s is often preoccupied solely with "successful" concepts and therapeutic approaches. The case of German-Canadian neurologist Karl Stern (1906-1975) is very instructive, however, since the process of forced migration, for him, proved to be a transitionary process from his former cutting edge work in neuropathology and holist neurology in Germany to clinical psychiatry and the development of the new discipline of geriatric medicine in Canada.

  11. von Baer's law for the ages: lost and found principles of developmental evolution.

    Science.gov (United States)

    Abzhanov, Arhat

    2013-12-01

    In 1828, Karl Ernst von Baer formulated a series of empirically defined rules, which became widely known as the 'Law of Development' or 'von Baer's law of embryology'. This was one the most significant attempts to define the principles that connected morphological complexity and embryonic development. Understanding this relation is central to both evolutionary biology and developmental genetics. Von Baer's ideas have been both a source of inspiration to generations of biologists and a target of continuous criticism over many years. With advances in multiple fields, including paleontology, cladistics, phylogenetics, genomics, and cell and developmental biology, it is now possible to examine carefully the significance of von Baer's law and its predictions. In this review, I argue that, 185 years after von Baer's law was first formulated, its main concepts after proper refurbishing remain surprisingly relevant in revealing the fundamentals of the evolution-development connection, and suggest that their explanation should become the focus of renewed research.

This is justified in part by Mannheim's viewpoint that thought is a function of human existence, and this function emanates from needs based on social factors. He traces Mannheim's use of the term ideology (in Sociology, culminating With the Idea that “the birth and death of ideology depends on certain social, economic and 'ecological' factors”. Subsequently he deals with a whole line of aspects of the sociology of knowledge as expounded by Mannheim, culminating in the idea that shifts in views with regard to lifeview and underlying values take place when there is a rapid upward (vertical mobility, leading to uncertainties and a lack of trust in established values.

    Editors' Note Each year, the editorial board invites a distinguished member of the oceanographic community to contribute a prefatory chapter; this year, we were delighted when Karl Turekian, Sterling Professor of Geology and Geophysics at Yale, accepted our invitation. Over the course of a long and productive career, Dr. Turekian has pursued his interests in marine and atmospheric geochemistry by using natural radioactive and radiogenic isotopes to study Earth's evolution and the impacts of global change. He has also directed both the Center for the Study of Global Change at Yale and the Yale Institute for Biospheric Studies. In this interview, conducted by his former student Kirk Cochran, Dr. Turekian tells the story of his early career and discusses some of the major scientific challenges and opportunities faced along the way. His personal account of the rise of geochemistry is a charming story of how chance events and personalities impact scientific careers. His technical insight into the future of this field is illuminating, particularly for scientific outsiders who appreciate the central role of geochemistry in discerning and understanding patterns of global change.

  6. Karl Marx dan Konsep Perjuangan Kelas Sosial

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available ¬¬This article explores the history of the renowned world economic and political reformist, Karl Marx with a special focus on the social class concept. It also discusses to what extent that the Marx’s concept of social class struggle is capable to provide a way out to the proletariats, to free themselves from the chains of cruelty, violence and alienation in the capitalist system. Our main focal point is to scrutinize the relationship between the concepts of social class struggle and the need for a social revolution as a catalyst for the formation of a classless society. Along the way, we studied and analyzed the documents produced on the primary sources covering major works of Marx and the secondary sources consisting reviews of the Marx’s class concept. As a result, we found out that Marx’s concept of class fight is competent to represent the oppressed group to battle for their freedom rights. The Proletariat dictatorship attitude was used as their main shield to face the threat of the capitalist class. Marx’s ultimate success is realized through a burst of ideas and beliefs that supports the ideas of egalitarian Communism although many contradictions arise between the ideas of Marx and the 20th centuries Communism when they are translated into practice.

  7. Karl Mannheim’s Jewish Question

    Directory of Open Access Journals (Sweden)

    David Kettler

    2012-04-01

    Full Text Available In this paper, we explore Karl Mannheim’s puzzling failure (or refusal to address himself in any way to questions arising out of the position of Jews in Germany, either before or after the advent of Nazi rule—and this, notwithstanding the fact, first, that his own ethnic identification as a Jew was never in question and that he shared vivid experiences of anti-Semitism, and consequent exile from both Hungary and Germany, and, second, that his entire sociological method rested upon using one’s own most problematic social location—as woman, say, or youth, or intellectual—as the starting point for a reflexive investigation. It was precisely Mannheim’s convictions about the integral bond between thought grounded in reflexivity and a mission to engage in a transformative work of Bildung that made it effectively impossible for him to formulate his inquiries in terms of his way of being Jewish. It is through his explorations of the rise and fall of the intellectual as socio-cultural formation that Mannheim investigates his relations to his Jewish origins and confronts the disaster of 1933. The key to our puzzle is to be found in the theory of assimilation put forward in the dissertation of his student, Jacob Katz.

  8. Information Systems Foundations - Karl Popper's third world

    Directory of Open Access Journals (Sweden)

    Craig McDonald

    2002-11-01

    Full Text Available The various information professions have matured separately over the years, developing different bodies of theory and practice to meet their evolving purposes and needs. A problem arises however, when different information professions address the same knowledge domain and there is no explicit correspondence between the conceptual structures embedded independently in each. In this situation, a knowledge worker involved in the domain is faced with a range of possibly incompatible structures presented in different forms by a range of information professions. This is a common problem that is being exacerbated by the explosion in information production and the widening access to information distribution technology, notably the World Wide Web. Information Systems now need to combine the best of what the information professions in a domain have to offer the domain’s knowledge workers. This paper examines the problem by exploring one of the foundations of the information disciplines - Karl Popper’s 3 Worlds theory, applying it to a case study and suggesting that the Information Systems discipline alone has a sufficiently broad agenda to integrate the various Informatics themes needed to support today’s knowledge workers.

It describes Karl Barth’s personality and shows how his theology was put to practice in writing, in teaching, in debate, in conflict, in friendship and in opposition. Some negative comments on Barth are for example levelled at his liturgical insensitivity, unbalanced and exclusive emphasis on preaching, and his individualistic dislike of the established church, its governing structures and baptismal practice. The article focuses on Barth’s impulses for the discipline of dogmatics and demonstrates developments and directions in his work. Critically reservations regarding instances where it might seem better for theologians not to follow Barth, are  specified.    The  article  also  offers  a  glimpse  into  the  future  of  dogmatic theology seen through the lens of Karl Barth.

    Insofar as Sir Karl Raimund Popper's writings deal with political statements, they are evident; yet insofar as they deal with scientific issues, they are incorrect and misleading. If applied to the concrete implementation of science, such as distribution of research funds and (peer) review, they would seriously hamper progress.

  5. Rheologie von Beschichtungen

    Science.gov (United States)

    Schäffler, Michael

    Die Rheologie beschreibt die Fließ- und Deformationseigenschaften von Materialien. Der Begriff Rheologie ist aus dem Griechischen abgeleitet: rhein - fließen. Erst im Jahre 1930 entwickelte E.C. Bingham und M. Reiner in Easton (USA) die Rheologie zu einer eigenständigen Wissenschaft. Aber bereits seit dem 17. Jahrhundert wurden wesentliche Einzelbeiträge zu Fließphänomenen veröffentlich, so z.B. 1676 von R. Hooke (Hookesches Gesetz) und 1687 von I. Newton (Newtonsches Gesetz). Die Rheologie hat sich bis heute immer mehr zu einer interdisziplinären Wissenschaft entwickelt, die die mechanischen Eigenschaften von Materialien charakterisiert.

  12. [Karl Jaspers and the challenges of social psychiatry].

    Science.gov (United States)

    Jäger, Markus; Lang, Fabian U; Becker, Thomas

    2015-01-01

    Karl Jaspers, in his book "General Psychopathology", argued for methodological pluralism rather than theoretical dogmatism. He formulated a methodological order of psychopathology with a distinction between "explanation" (objective psychopathology) and "understanding" (subjective psychopathology, psychopathology of meaning). The latter approach focused on patients' subjective experience and biographical issues. Karl Jaspers emphasised social factors in the genesis and course of mental disorders. Following a multiperspective concept, from Jaspers' viewpoint social psychiatry should consider itself of equal importance with biological and psychotherapeutic psychiatry. Therefore, uncritical generalization of one of these perspectives should be avoided. Personalized psychiatry, apart from searching biological markers to tailor treatment should identify psychosocial factors and subjective meaning. Concepts of recovery should not ignore biological foundations in mental disorders.

    2014-01-01

    Full Text Available Karl Popper once criticizes the positivistic paradigm by means of what he calls the theory of falsification. To him, the positivistic paradigm constitutes a failure simply because it cannot distinguish between science and prude science, that is, between empirical method and non-empirical method. In the scientific knowledge, empirical science, mathematics and logic must be differentiated, something that the positivistic paradigm has failed to do. This paradigm furthermore, did not have a clear picture what logic-based science is, empirical knowledge and psychology of knowledge. It also fails to properly understand knowledge that springs from tradition, emotion, authority and so forth. All positivistic paradigms such as that of Karl Max’s Historicism, Freud’s theory of Psycho Analysis, Adler’s theory of Individual Analysis and Newton’s theory of Gravitation fall into this trap of failure.

  2. Test of Von Baer's law of the conservation of early development.

    Science.gov (United States)

    Poe, Steven

    2006-11-01

    One of the oldest and most pervasive ideas in comparative embryology is the perceived evolutionary conservation of early ontogeny relative to late ontogeny. Karl Von Baer first noted the similarity of early ontogeny across taxa, and Ernst Haeckel and Charles Darwin gave evolutionary interpretation to this phenomenon. In spite of a resurgence of interest in comparative embryology and the development of mechanistic explanations for Von Baer's law, the pattern itself has been largely untested. Here, I use statistical phylogenetic approaches to show that Von Baer's law is an unnecessarily complex explanation of the patterns of ontogenetic timing in several clades of vertebrates. Von Baer's law suggests a positive correlation between ontogenetic time and amount of evolutionary change. I compare ranked position in ontogeny to frequency of evolutionary change in rank for developmental events and find that these measures are not correlated, thus failing to support Von Baer's model. An alternative model that postulates that small changes in ontogenetic rank are evolutionarily easier than large changes is tentatively supported.

  3. Reaction rates between water and the Karl Fischer reagent.

    1974-04-01

    Reaction rates between water and the Karl Fischer reagent have been determined by potentiometric measurement for various compositions of the Karl Fischer reagent. The study has been made with an iodine complex concentration of 0.3-1.2 mM and sulphur dioxide complex at 0.01-0.5M. The concentration of excess of pyridine had no measurable effect on the rate of the main reaction. The reaction was found to be first-order with respect to iodine complex, to sulphur dioxide complex, and to water. The rate constant was (1.2+/-0.2) x 10(3) 1(2). mole(-2). sec(-1). In an ordinary titration it is therefore essential to keep the sulphur dioxide concentration high for the reaction to go to completion within a reasonable time. The extent of side-reactions was found to be independent of the iodine concentration at low concentrations. The side-reactions increased somewhat with increasing sulphur dioxide pyridine concentrations and decreased to about 60% when the temperature was lowered from 24 degrees to 7 degrees.

    Full Text Available Can the great 20th century systematic theologian Karl Barth justify the fundamental beliefs he holds regarding the priority of God’s revelation in Jesus Christ as put forward in his impressive and comprehensive Kirchliche Dogmatik? Is it enough and thus theologically justifiable to simply state in the words of Barth that the best theology would need no advocates: it would prove itself? In my appraisal of Barth’s epistemological stance, I would like to argue in this article that his stance in the first place, does not only lead to a total isolation of theological reflection, but secondly through his highly exclusive claim, takes on the character of a personal religious credo expanded into a comprehensive doctrine beyond any form of control, and ultimately thirdly, becomes methodologically in essence a specifically Barthian theology from below. Wenn die Theologie sich eine Wissenschaft nennen lässt oder selber nennt, so kann sie damit keinerlei Verpflictung übernehmen, sich an den für andere Wissenschaften gültigen Massstäbem messen zu lassen.

Menten of the Max-Planck-Institute for Radioastronomy in Bonn, Germany. The Jansky Lectureship is an honor established by the trustees of AUI to recognize outstanding contributions to the advancement of astronomy. Karl M. Menten Professor Karl M. Menten CREDIT: NRAO/AUI Click on image for high-resolution file (433 KB) Professor Menten is an extraordinarily productive scientist whose research has improved our fundamental understanding in a number of areas of astronomy. He has studied the chemistry of molecular clouds from which new stars are formed, the process of star formation in our own Milky Way Galaxy and in the early Universe, and the outer atmospheres of stars nearing the end of their "normal" lives. In 1991, Menten used NRAO's 140-foot Telescope at Green Bank, West Virginia, to discover strong radio emission from methanol masers in star-forming regions. These masers amplify, or strengthen, radio emission the same way a laser amplifies visible-light emission. Menten developed the observation of these methanol masers into a powerful tool for studying the formation of stars much more massive than our Sun, because the strong maser emission points astronomers to the stellar birthplaces. In addition, Menten pioneered the use of ultra-high-resolution observations with NRAO's Very Long Baseline Array to observe masers to make precision determinations of the structure, size and dynamics of the Milky Way. Menten received his doctoral degree in 1987 from the University of Bonn, Germany. He then joined the Harvard-Smithsonian Center for Astrophysics, working there until 1996, when he became the Director for Millimeter and Submillimeter Astronomy at the Max-Planck-Institute for Radioastronomy. In addition to that position, he also has been a Professor for Experimental Astrophysics at the University of Bonn since

  11. Descriptive psychopathology, phenomenology, and the legacy of Karl Jaspers.

    Science.gov (United States)

    Häfner, Heinz

    2015-03-01

    With his early publications (1910-1913), Karl Jaspers created a comprehensive methodological arsenal for psychiatry, thus laying the foundation for descriptive psychopathology. Following Edmund Husserl, the founder of philosophical phenomenology, Jaspers introduced phenomenology into psychopathology as "static understanding," ie, the unprejudiced intuitive reproduction (Vergegenwärtigung) and description of conscious phenomena. In a longitudinal perspective, "genetic understanding" based on empathy reveals how mental phenomena arise from mental phenomena. Severance in understanding of, or alienation from, meaningful connections is seen as indicating illness or transition of a natural development into a somatic process. Jaspers opted for philosophy early. After three terms of law, he switched to studying medicine, came to psychopathology after very little training in psychiatry; to psychology without ever studying psychology; and to a chair in philosophy without ever studying philosophy. In the fourth and subsequent editions of his General Psychopathology, imbued by his existential philosophy, Jaspers partly abandoned the descriptive method.

    1991-12-01

    The eminent mathematical physicist Sir Hermann Bondi once said: “There is no more to science than its method, and there is no more to its method than Popper has said.” Indeed, many regard Sir Karl Raimund Popper the greatest philosopher of science in our generation. Much of what Popper “has said” refers to physics, but physicists, generally speaking, have little knowledge of what he has said. True, Popper's philosophy of science and, in particular, his realistic interpretation of quantum mechanics deviates considerably from the generally accepted doctrine. But as Popper, rightly I think, points out, it is precisely the proliferation of divergent theories which promotes the growth of scientific knowledge; it would be a danger for physics if physicists were dogmatically tied to a single theory or would not test their theory against alternatives. It is for this purpose that, on the occasion of the nonagenarian celebration of Popper's birthday, the present essay has been written.

  17. Karl Heinrich Ulrichs: First Theorist of Erotic Age Orientation.

    Janssen, Diederik F

    2017-01-01

    The nomination of Karl Heinrich Ulrichs (1825-1895) as the first theorist of homosexuality may be placed in the oblique light of his eligibility for the nomination as the first theorist of erotic age orientation. In Ulrichs's pamphlets, "man-manly" homosexuality emerged as a particular age orientation, with a subsequent typological breakdown that, importantly, blended gender orientation and age orientation. Into the early 20th century, erotic age orientation remained bound up with the classification and emancipation of what here was demarcated as Urningsliebe. Ulrichs's pioneering and shifting comments on age eventually fed into his legal model of consenting adults in private. They also provide a starting point for the historical understanding of the trope of "grooming pedophile" as it, arguably, crossfaded with that of the "seducing homosexual" after the latter's depsychiatricization across the Western world.

    Full Text Available In this paper I intend to thoroughly analyse Karl Popper’s relation to metaphysics. I start with his first writings, where he states the differences between science, pseudoscience and metaphysics. I then describe how his thoughts on the subject evolved to culminate in his reflection on metaphysical research programmes and the need for a revival of natural philosophy. A major concern is Popper’s famous testability criterion to set apart science from non-science. I point at the problems of the conception of metaphysics as non-testable theories (which are similar to the problems of the conception of metaphysics as theories involving unobservables and, in order to avoid these problems, I propose to retain nothing but the traditional conception of metaphysics as the general theories about the nature of the world. This leads me to the conclusion that science is not only an empirical task but also, and in a very important sense, a speculative one.

A partir de um resgate do caráter crítico e revolucionário do marxismo de Marx, Korsch realiza uma crítica radical ao revisionismo e leninismo. Para tal, ele não só resgata o verdadeiro caráter da dialética marxista e da concepção materialista da história, como exige a coerência dessa concepção ao defender o princípio de aplicação dela a si mesma. Assim ele lança as bases de um marxismo não dogmático, para o qual é o vínculo com o proletariado que mostra o caráter do marxismo e não ideologias petrificadas. Abstract: This article thematizes Marxism of Karl Korsch, focusing on its non dogmatic. From a rescue of criticality and revolutionary Marxism of Marx, Korsch performs a radical critique of revisionism and Leninism. To do so, he not only rescues the true character of Marxist dialectics and materialist conception of history, as this concept requires consistency in defending the principle of applying it to herself. So he lays the foundations of a non-dogmatic Marxism, to which is the bond with the proletariat that shows the character of Marxism and not petrified ideologies. Key words: Marxism, dogmatism, criticism, historical materialism, dialectical.

  8. Testing the null hypothesis: the forgotten legacy of Karl Popper?

    Science.gov (United States)

    Wilkinson, Mick

    2013-01-01

    Testing of the null hypothesis is a fundamental aspect of the scientific method and has its basis in the falsification theory of Karl Popper. Null hypothesis testing makes use of deductive reasoning to ensure that the truth of conclusions is irrefutable. In contrast, attempting to demonstrate the new facts on the basis of testing the experimental or research hypothesis makes use of inductive reasoning and is prone to the problem of the Uniformity of Nature assumption described by David Hume in the eighteenth century. Despite this issue and the well documented solution provided by Popper's falsification theory, the majority of publications are still written such that they suggest the research hypothesis is being tested. This is contrary to accepted scientific convention and possibly highlights a poor understanding of the application of conventional significance-based data analysis approaches. Our work should remain driven by conjecture and attempted falsification such that it is always the null hypothesis that is tested. The write up of our studies should make it clear that we are indeed testing the null hypothesis and conforming to the established and accepted philosophical conventions of the scientific method.

  9. Centenary of Karl Jaspers's general psychopathology: implications for molecular psychiatry.

    Science.gov (United States)

    Thome, Johannes

    2014-01-01

    Modern molecular psychiatry benefits immensely from the scientific and technological advances of general neuroscience (including genetics, epigenetics, and proteomics). This "progress" of molecular psychiatry, however, will be to a degree "unbalanced" and "epiphytic" should the development of the corresponding theoretical frameworks and conceptualization tools that allow contextualization of the individual neuroscientific findings within the specific perspective of mental health care issues be neglected. The General Psychopathology, published by Karl Jaspers in 1913, is considered a groundbreaking work in psychiatric literature, having established psychopathology as a space of critical methodological self-reflection, and delineating a scientific methodology specific to psychiatry. With the advance of neurobiology and molecular neuroscience and its adoption in psychiatric research, however, a growing alienation between current research-oriented neuropsychiatry and the classical psychopathological literature is evident. Further, consensus-based international classification criteria, although useful for providing an internationally accepted system of reliable psychiatric diagnostic categories, further contribute to a neglect of genuinely autonomous thought on psychopathology. Nevertheless, many of the unsolved theoretical problems of psychiatry, including those in the areas of nosology, anthropology, ethics, epistemology and methodology, might be fruitfully addressed by a re-examination of classic texts, such as Jaspers's General Psychopathology, and their further development and adaptation for 21st century psychiatry.

  10. Falsifications and corroborations: Karl Popper's influence on systematics.

    Science.gov (United States)

    Helfenbein, Kevin G; DeSalle, Rob

    2005-04-01

    Over the last three decades, the philosophy of Karl Raimund Popper has had a strong influence on the field of systematic biology. Unequivocally, no other philosopher's work has had such an influence during this formative period in systematics. Much, but not all, of the early discourse on Popper and systematics dealt with the philosophical basis of systematics as a science. More recently Popper's work has been discussed in the systematics literature in relation to specific methodologies such as parsimony and maximum likelihood. In this paper, we provide the reader with a concise summary of Popper's ideas relevant to systematics, review the systematic literature invoking or declining Popper's importance to the field, and make a recommendation for the future course of philosophical thinking in systematics. We try to make clear various authors' interpretations of Popper's work and how those interpretations have impacted systematic thought. Although the reader may come away from this review with a clearer idea of Popper's relevance or lack thereof, our primary hope is that the reader will be compelled to question him- or herself about the philosophical basis of the systematic work that he or she does, and to delve into the literature herein cited. We begin by presenting a synopsis of Popper's philosophical views to allow those views to be placed in the context of systematics.

  11. Karl Marx and the Study of Media and Culture Today

    Full Text Available The task of this paper discusses the role of Marx in analysing media, communica-tion and culture today. An analysis of three contemporary Cultural Studies works – Lawrence Grossberg’s monograph Cultural Studies in the Future Tense, John Hartley’s monograph Digital Futures for Cultural and Media Studies and Paul Smith’s edited volume The Renewal of Cultural Studies – shows that there is an agreement that the economy needs to be taken more into account by Cultural Studies, but disagreement on which approach should be taken and what the role of Karl Marx’s works shall be. The paper argues that Marx’s labour theory of value is especially important for critically analysing the media, culture and communica-tion. Labour is still a blind spot of the study of culture and the media, although this situation is slowly improving. It is maintained that the turn away from Marx in Cultural and Media Studies was a profound mistake that should be reverted. Only an engagement with Marx can make Cultural and Media Studies topical, politically relevant, practical and critical, in the current times of global crisis and resurgent critique.

  12. Karl Pearson and eugenics: personal opinions and scientific rigor.

    Delzell, Darcie A P; Poliak, Cathy D

    2013-09-01

    The influence of personal opinions and biases on scientific conclusions is a threat to the advancement of knowledge. Expertise and experience does not render one immune to this temptation. In this work, one of the founding fathers of statistics, Karl Pearson, is used as an illustration of how even the most talented among us can produce misleading results when inferences are made without caution or reference to potential bias and other analysis limitations. A study performed by Pearson on British Jewish schoolchildren is examined in light of ethical and professional statistical practice. The methodology used and inferences made by Pearson and his coauthor are sometimes questionable and offer insight into how Pearson's support of eugenics and his own British nationalism could have potentially influenced his often careless and far-fetched inferences. A short background into Pearson's work and beliefs is provided, along with an in-depth examination of the authors' overall experimental design and statistical practices. In addition, portions of the study regarding intelligence and tuberculosis are discussed in more detail, along with historical reactions to their work.

    Dr. Theodore von Karman, co-founder of the Jet Propulsion Laboratory (JPL) Pasadena, California was an aeronautical theoretician. His contributions in the fields of aerodynamics and aeronautical engineering are well documented and well known to every aerospace engineer. He was the first winner of the prestigious U.S. Medal of Science presented to him by President John F. Kennedy. As well as being co-founder of JPL, he also was principal founder of a major rocket propulsion firm (Aerojet-General Corp.), the top science advisor to the U.S. Air Force during its transition to jet propulsion aircraft and the top science advisor to NATO. He was, during much of this time, the fountainhead of aerodynamic thought as head of the Guggenheim Aeronautical Laboratory at the California Institute of Technology (GALCIT) in Pasadena, California. In the May 1956 issue of the Journal of Aeronautical Sciences, it was said of him that 'No other man has had so great an impact on the development of aeronautical science in this country. Hundreds of young men became his students and scientific collaborators and were inspired to greater effort.' Dr. William H. Pickering, then director of JPL said in 1960 'We wouldn't have an aeronautical science as we know it today, if it weren't for Dr. Thoedore von Karman.' Under his guidance, Caltech's 10 foot wind tunnel was designed, built and operated. Industry firms such as Douglas, Northrop, Hughes, Lockheed, North American, Vultee and Consolidated all tested new aeronautical designs and concepts in GALCIT's tunnel. Even Boeing's own high-speed wind tunnel was heavily influenced by suggestions from von Karman. The National Advisory Committee for Aeronautics (NACA) became so concerned about GALCIT's growing influence over West coast aviation, it erected the Ames Laboratory in Sunnyvale, California in part to deter an ever widening aeronautical gap that had formed between NACA and GALCIT. From 1936 to 1940, Caltech stood alone as the only university

    Full Text Available The idea of the Christian universalism is a key-subject of Balthasar’s theology. The proprium of this autor appears more clearly analysing the distance in the subject of analogia entis and the natural theology which Barth maintains. A basic element of Bathasar’s reflection about the Christian universalism has its roots in the origin of the assertion that the creation in Christ is united with the contemplation of the cosmic Christ and with the will to emphasize the universal character of the salvation happened in Christ (the concretum universale. Thus the approach is a profound comprehension of the salvation “in Christ”. The Chalcedonic formula enlarged since the fourth Lateran Council becomes a “law” for the interpretation of the (metaphysical reality. Balthasar propounds in this way an ontology in those center the personal reality is situated. At the end the reader finds a prospective critique to Balthasar’s position

  18. O pensamento epistemológico de Karl Popper

    2007-01-01

    Full Text Available Desde a antiguidade, o critério de demarcação entre o que é ciência e o que não é ciência tem sido discutido. A noção que então se tinha de ciência coincidia com a busca do saber absoluto. Tornava-se necessária, para os pensadores gregos, entre eles, Aristóteles, Pitágoras e Descartes, a consolidação de uma distinção precisa entre o saber contingente e o saber necessário, pois o único discurso que poderia satisfazer às exigências do rigor científico era aquele que apontasse, nos fenômenos, conexões causais cuja necessidade pudesse ser demonstrada. Antes de Popper, o pensamento filosófico ocidental atravessou séculos tentando explicar por que nossas teorias frequentemente estavam erradas. Em sua obra fundamental, A Lógica da Pesquisa Científica, Karl Popper coloca em novos termos a discussão epistemológica ao demonstrar que o erro, em vez de ser um mal que pode ser evitado através do recurso a algum procedimento metodológico específico, constitui componente inevitável de qualquer teoria científica, sendo o motor pelo qual a ciência se move. Buscando captar a lógica do desenvolvimento da ciência, Popper inicia sua exposição destruindo aquele que talvez fosse, de todos os princípios filosóficos, o mais caro aos cientistas e à boa parte dos filósofos de seu tempo: o princípio da indução como método de procedimento científico. Neste artigo, abordam-se alguns dos principais tópicos do pensamento popperiano, como o princípio da indução, a concepção de ciência e a falseabilidade. Também se intenta aduzir alguns debates filosóficos, justapondo às opiniões de Popper e de críticos ao seu pensamento. A contestação aludida ao pensamento popperiano advém do professor Thomas S. Kuhn, da Princeton University. Kuhn objeta à opinião de Popper quando este afirma que o cientista é um solucionador de problemas. Para Kuhn, os cientistas são solucionadores de enigmas e não de problemas. Essa posi

    Different designs of a semiopen, drainable cathode compartment of a medium-sized coulometric Karl Fischer (KF) cell for the determination of water in the range 0.1-500 microg were evaluated. The main criterion for the design was to keep the resistance between the anolyte and catholyte low enough to permit the generation of currents larger than 20 mA (for an output voltage of 28 V). It was found that a good compromise between the size of this current and a minimal influence from diffusing/migrating oxidizable reduction products from the catholyte was achieved by means of an interface having a channel length and diameter of 8 and 2.1 mm, respectively (catholyte volume, approximately 1 mL). To show the general applicability of the concept, the following different types of coulometric reagents suitable for nonpolar and polar samples, as well as for samples containing active carbonyl compounds, were investigated: Hydranal Coulomat A, AD, AK, AG-H (modified with chloroform, Merck), and two homemade methanolic reagents modified with 40% (v/v) chloroform and 50% (v/v) formamide, respectively. Except for Hydranal Coulomat A, the mean value of five consecutive titrations of 50 microg water did not deviate by more than 0.2% from the expected value for all reagents. Draining after every titration was sufficient to obtain accurate results, even for Coulomat A which, when used in the commercial diaphragm-free system of Metrohm, gave values which were about 10% too high. As compared to earlier reported results for diaphragm-free coulometry, the descibed modified cell represents a significant improvement, mainly because of the high accuracy achieved for all types of reagents.

  2. Coulometric determination of trace water in active carbonyl compounds using modified Karl Fischer reagents

    Nordin-Andersson, I.; Cedergren, A.

    1987-03-01

    Improved conditions for the coulometric determination of trace water in samples containing potentially interfering substances like aldehydes and ketones were obtained by using a formamide-based, rapidly reacting Karl Fischer reagent in which methanol was replaced by 2-methoxyethanol. The shape of the potentiometric titration curves obtained by titrating spent Karl Fischer reagents with iodine indicates a less degree of triiodide formation in the presence of formamide. The corresponding increase in iodine results in a more rapid overall reaction rate since the reaction involving iodine is much more rapid than that with triiodide. For water amounts corresponding to less than 0.1% the stoichiometry of the Karl Fischer reaction was found to be 1:1, relatively independent of the concentration of 2-methoxyethanol. For larger amounts of water this stoichiometric ratio was attained by using a reagent containing 2-methoxyethanol/formamide 80/20 (v/v), 0.6 M imidazole, and 0.4 M sulfur dioxide.

    The Karl G. Jansky Very Large Array is a recently completed rejuvenation of the VLA, providing observers with significantly increased continuum sensitivity and spectral survey speeds (by factors of 100 or more in select cases) from 1-50 GHz and in key bands below 1 GHz. Given the potential for new centimeter-wavelength sky surveys with this enhanced facility, the NRAO VLA Sky Survey (VLASS) has been initiated to explore the science and technical opportunities of a new large survey. A community-led Science Survey Group (SSG) will define the science program and key components of VLASS, and NRAO will support its technical design and implementation. The VLASS could start observing in early 2015, with the data available immediately with no proprietary period and science data products provided to the community in a timely manner. The new VLA can image young stars and massive black holes, measure the strength and topology of the cosmic magnetic field, follow the rapid evolution of energetic phenomena, and study the formation and evolution of stars, galaxies, AGN, and the Universe itself. We can follow the evolution of gas and galaxies and particles and fields to bridge the eras from cosmic dawn to the dawn of new worlds. To address these and other key science challenges requires the VLASS to address a number of key challenges in data management, computation, image processing, and analysis. The development and implementation of capable, efficient, and robust pipeline processing of data, and the production of a basic suite of science data products such as images and catalogs, are all high priorities for VLASS. We will describe the salient capabilities of the Jansky VLA, and highlight complementarity with multi-wavelength multi-messenger sky surveys with other facilities, ultimately leading into the era of the LSST. Exemplary VLA science and commissioning observations will illustrate these features. We will also summarize the outcome of the public NRAO VLASS Science Planning

    Rheumatoid arthritis (RA) is a crippling joint disease affecting over 20 million people worldwide. The cause of RA is most probably linked to the triad of microbial trigger, genetic association and autoimmunity and can be explained using the philosophical method of Karl Popper or Popperian sequences. Ten "Popper sequences" have been identified which point to the urinary microbe Proteus mirabilis as the cause of RA: Popper sequence 1 establishes that HLA-DR4 lymphocytes injected into a rabbit evoke specific antibodies against Proteus bacteria. Popper sequence 2 establishes that antibodies to Proteus bacteria are present in RA patients from 14 different countries. Popper sequence 3 establishes that antibodies to Proteus bacteria in RA patients are disease specific since no such antibodies are found in other conditions. Popper sequence 4 establishes that when RA patients have high titres of antibodies to Proteus such bacteria are found in urinary cultures. Popper sequence 5 establishes that only Proteus bacteria and no other microbes evoke significantly elevated antibodies in RA patients. Popper sequence 6 establishes that the "shared epitope" EQR(K)RAA shows "molecular mimicry" with the sequence ESRRAL found in Proteus haemolysin. Popper sequence 7 establishes that Proteus urease contains a sequence IRRET which has "molecular mimicry" with LRREI found in collagen XI of hyaline cartilage. Popper sequence 8 establishes that sera obtained from RA patients have cytopathic properties against sheep red cells coated with the cross-reacting EQR(K)RAA and LRREI self-antigen peptides. Popper sequence 9 establishes that Proteus sequences in haemolysin and urease as well as the self antigens, HLA-DR1/4 and collagen XI, each contain an arginine doublet, thereby providing a substrate for peptidyl arginine deiminase (PAD) to give rise to citrulline, which is the main antigenic component of CCP, antibodies to which are found in early cases of RA.

    Volker Roelcke, the well-known historian of medicine, wrote a biographical sketch on his father's role in National Socialism. Karl Roelcke (1907-1982) was an important hygienist at the University of Heidelberg and assistant to Ernst Rodenwaldt (1878-1965). Attempts to discuss the Nazi issue with his father directly ended unsuccessfully in the 1970s. In his essay of 2014, Volker Roelcke portrayed his father as quite sophisticated, but did not mention all aspects of his work. The present essay therefore offers new insights into the person of Karl Roelcke which are not constrained by family interests.

    Certified reference materials (CRMs) of water content are widely used in the calibration and validation of Karl Fischer coulometry and volumetry. In this study, the water content of the water saturated 1-octanol (WSO) CRM was certified by Karl Fischer coulometry, volumetry and quantitative nuclear magnetic resonance (Q NMR). The water content recovery by coulometry was 99.76% with a diaphragm-less electrode and Coulomat AG anolyte. The relative bias between the coulometry and volumetry results was 0.06%. In Q NMR, the water content of WSO is traceable to the International System (SI) of units through the purity of internal standard. The relative bias of water content in WSO between Q NMR and volumetry was 0.50%. The consistency of results for these three independent methods improves the accuracy of the certification of the RM. The certified water content of the WSO CRM was 4.76% with an expanded uncertainty of 0.09%.

    On the basis of mostly unpublished sources, the author reconstructs the life of the Hungarian writer Viktor von Dirsztay (1884?-1935) who was personally acquainted with many expressionist artists and writers, e. g. with Karl Kraus, Oskar Kokoschka, Herwarth Walden, Walter Hasenclever, Hermann Broch and Arthur Schnitzler. This association puts Freud into closer proximity with the cultural avantgarde of his times than previously realized. Between 1910 and 1920 Dirsztay underwent several phases of analysis with Freud; then he was treated by Theodor Reik. The overall length of his analysis with Freud is almost unparalleled. The article discusses whether and in which way Dirsztay's writings might have been influenced by his analyses and how Freud and Reik might have drawn upon their experiences with this patient. It is argued that likely references can be discovered in both authors' theories of masochism. There is an intriguing late remark of Dirsztay's that he was "ruined by analysis".

    2014-01-01

    The search for life in the solar system depends upon discovering the right moments in planetary evolution: when habitable environments existed, when they declined, and when geologic processes operated to preserve traces of life after death. However, an incomplete knowledge of absolute Martian geochronology limits our ability to understand the timing of Martian evolutionary milestones, major climate changes, and stratigraphic epochs [1, 2]. Absolute dating relates these habitability markers to planetarywide geologic, atmospheric, and climate history places, and ties their occurrence to the history of the solar system, especially the Earth-Moon system and the timescale of evolution of life on Earth. KArLE is being developed to anchor the relative timeline of geological events to an absolute chronology that puts Mars into a wider solar system context. KArLE makes its measurements on rock samples that can be obtained by landers or rovers and inserted into a small, mechanically simple chamber. KArLE interrogates the samples using laser-induced breakdown spectrocopy (LIBS), mass spectrometry, and optical imaging. The KArLE experiment is flexible enough to accommodate any partner providing these instrument components, a creative approach that extends the ability of mission payloads to accomplish an additional highly-desirable science measurement for low cost and risk and minimal extra hardware.

  9. Developement of the Potassium-Argon Laser Experiment (KArLE) for In Situ Geochronology

    Science.gov (United States)

    Cohen, Barbara A.

    2012-01-01

    Absolute dating of planetary samples is an essential tool to establish the chronology of geological events, including crystallization history, magmatic evolution, and alteration. Thus far, radiometric geochronology of planetary samples has only been accomplishable in terrestrial laboratories on samples from dedicated sample return missions and meteorites. In situ instruments to measure rock ages have been proposed, but none have yet reached TRL 6, because isotopic measurements with sufficient resolution are challenging. We have begun work under the NASA Planetary Instrument Definition and Development Program (PIDDP) to develop the Potassium (K) - Argon Laser Experiment (KArLE), a novel combination of several flight-proven components that will enable accurate KAr isochron dating of planetary rocks. KArLE will ablate a rock sample, measure the K in the plasma state using laser-induced breakdown spectroscopy (LIBS), measure the liberated Ar using quadrupole mass spectrometry (QMS), and relate the two by measuring the volume of the abated pit using a optical methods such as a vertical scanning interferometer (VSI). Our preliminary work indicates that the KArLE instrument will be capable of determining the age of several kinds of planetary samples to 100 Myr, sufficient to address a wide range of geochronology problems in planetary science. Additional benefits derive from the fact that each KArLE component achieves analyses common to most planetary surface missions.

    Full Text Available Hans Urs von Balthasar (1905-1988 y Karl Rahner (1904-1984 fueron dos grandes figuras de la teología del siglo XX. Sus obras influyeron en el rumbo de las principales corrientes de pensamiento que confluyeron en el acontecimiento del Concilio Vaticano II y que impulsaron la profunda renovación teológica a él vinculada. Por ello han abundado estudios sobre sus respectivas obras, ambas enormes. La relación entre ellos ha sido igualmente objeto de interés. Tuvieron importantes puntos en común, pero también se distanciaron, debido sobre todo a divergencias filosófico-teológicas fundamentales. Este artículo aborda la relación desde el punto de vista de Rahner: su propia comprensión de la apuesta por la perspectiva trascendental; pero también desde el ángulo de cómo von Balthasar valoró esa apuesta. Finalmente se intenta una reflexión sobre aquello esencial de esta interlocución que hoy debería ser rescatado para una visión teológica más amplia y más profunda del misterio de la acción salvadora de Dios en Cristo.Hans Urs von Balthasar (1905-1988 and Karl Rahner (1904-1984 were two great figures of 20th century theology. Their works influenced the course of the principal currents of thought that converged in the event of Vatican Council II, and propelled the profound theological renewal linked to it. For this reason studies abound regarding their respective works, in both cases enormous. The relationship between them has equally been an object of interest. They had important points in common, but also drew apart on others, owing principally to fundamental philosophico-theological divergences. This article undertakes the relationship from Rahner´s point of view-his own understanding of placing a stake in the transcendental perspective-but also from the angle of how von Balthasar valued that stake. Finally the author attempts a reflection on that essential quality of this interchange that today ought to be recovered for a wider

Die Maschinen werden breiter und länger und besitzen mehr Achsen und komplexere Lenksysteme als in der Vergangenheit. Beim landwirtschaftlichen Wegebau hat dies insbesondere Auswirkungen auf die Planung der Kurven. In der Untersuchung wurden die Schleppkurven aktueller Landmaschinen aufgenommen und es wurde geprüft, ob sie mithilfe einer Software simuliert werden können. Dabei zeigt sich, dass die verwendete Simulationssoftware für die Bestimmung von Schleppkurven für Landmaschinen mit komplexen Lenksystemen hinreichend genau ist.

    The association between von Recklinghausen's disease and pheochromocytoma is present about 10% of cases. We report a case of 49 years old women who presented with elevated blood pressure and von Recklinghausen's neurofibromatosis. Laboratory examination showed a marked level in the urinary excretion of cathecholamine. The computed tomography showed a right adrenal tumor suggesting a pheochromocytoma. The adrenalectomy was realised by transabdominal approach and the histological examination confirmed a benign pheochromocytoma. The authors discuss the pathogenetic hypothesis of this rare pathological association, the diagnostic methods and the therapeutic procedure.

    Full Text Available The aim of this article is to criticize the traditional representation of Karl Marx’s journalistic works, usually forgotten by a misleading canon that assumes his articles only as a minor work. One of the problems of this traditional conception is that it dissociates his theoretical and economic contributions from the historical development of the author’s thought (and also from its material roots. We will try to point the importance of Karl Marx’s mature journalism in two areas: in the construction of the central concepts of his critic against the capitalist mode of production (surplus value, a multilineal historical perspective, a global description of the world market, etc. and in the production of political cartographies to intervene in the class conflict. This article poses several hypothesis and tentative affirmations about Karl Marx’s journalism that may serve as a point of departure for a critical research.El objetivo de este artículo es criticar la representación tradicional del trabajo periodístico de Karl Marx, habitualmente olvidado por un canon engañoso que sólo asume sus artículos al precio de convertirlos en una obra menor.

    Directory of Open Access Journals (Sweden)

    Maret Vaher

    2016-09-01

    Full Text Available Between 1961 and his death, Karl Ristikivi published twelve historical works (eleven novels and one short story collection that form a conceptual whole. The lengthy period covered in these works raises questions about the purpose of the series. While Ristikivi’s Journal 1957–1968 was written nearly half a century ago, it has been available to a wider audience only since its publication in 2008. Although the writer’s works have been researched for several decades, his journal provides new insight into his creative intentions. Ristikivi’s biographical details reveal that he had a wide variety of interests, including history and mathematics. The writer first envisioned writing a series of 12 novels covering the period from the last Ice Age to the First World War while just a student. The journal entries reveal the mature writer’s plans for the historical cycle. First, the series would begin in the middle of the 13th century, specifically in 1255, and finish in 1945 at the end of the Second World War. Second, the author initially planned to write 24 books in which the events described would be separated by 30-year intervals in order to convey a change of generations. Consequently, the writer needed to find events that could be incorporated in this structure, rather than base the structure of his works on certain historical events. Ristikivi’s historical works portray a mythical world where the storyline features the perpetual recurrence of archetypes and replication of all events. His last novel Roman Diary (1976 mentions four eras: the age of gods, the age of heroes, the present (the „Bronze Age“, and the future age. The ages of gods and heroes have passed, and we have reached the third age. The protaganist of Roman Diary, Kaspar von Schmerzburg, longs for the second age – the age of heroes and chivalry. However, he senses that he must be content with the present age because the fourth - the future age - may be even worse as

    The Potassium (K) - Argon (Ar) Laser Experiment (KArLE) will make in situ noble-gas geochronology measurements aboard planetary robotic landers and roverss. Laser-Induced Breakdown Spectroscopy (LIBS) is used to measure the K abun-dance in a sample and to release its noble gases; the evolved Ar is measured by mass spectrometry (MS); and rela-tive K content is related to absolute Ar abundance by sample mass, determined by optical measurement of the ablated volume. KArLE measures a whole-rock K-Ar age to 10% or better for rocks 2 Ga or older, sufficient to resolve the absolute age of many planetary samples. The LIBS-MS approach is attractive because the analytical components have been flight proven, do not require further technical development, and provide complementary measurements as well as in situ geochronology.

    Full Text Available In 1919 het die eerste uitgawe van die epogmakende “Romerbrief” van Karl Barth verskyn. Van die tweede druk in 1922 sê hy dat “kein Stein mehr auf dem andem” gelaat is nie. So opspraakwekkend was hierdie boek dat in 1929 die 5de druk van die tweede, radikaal-hersiene uitgawe verskyn het. Intussen het nog ander werke van Barth en selfs oor Barth verskyn. 0ns noem o.a. sy Der Christ in der Gesellschaft (1920; Das Wort Gottes und die Theologie (1924; Vom Christlichen Leben (1926; Auferstehung der Toten (2.

Maar 1927 was veral belangrik vanweë die verskyning van Barth se eerste Dogmatiekboek: “Die Christliche Dogmatik im Entwurf. 1 Die Lehre vom Worte Gottes. Prolegomena zur Christlichen Dogmatik” . Voor dié datum het dwarsoor die wêreld, maar ook in Nederland wye reaksie op sy teologie ontstaan.

  2. Philipp Frank, Richard von Mises, and the Frank-Mises

    The theoretical physicist Philipp Frank (1884 1966) and the applied mathematician Richard von Mises (1883 1953) both received their university education in Vienna shortly after 1900 and became friends at the latest during the Great War.They were attached to the Vienna Circle of Logical Positivists and wrote an influential two-part work on the differential and integral equations of mechanics and physics, the Frank-Mises, of 1925 and 1927, with its second edition following in 1930 and 1935.This work originated in the lectures that the mathematician Bernhard Riemann (1826 1866) delivered on partial differential equations and their applications to physical questions at the University of Göttingen between 1854 and 1862, which were edited and published posthumously in1869 by the physicist Karl Hattendorff (1834 1882).The immediate precursor of the Frank-Mises, however, was the extensive revision of Hattendorff’s edition of Riemann’s lectures that the mathematician Heinrich Weber (1842 1913) published in two volumes, the Riemann-Weber, of 1900 and 1901, with its second edition following in 1910 and 1912. I trace this historical lineage, explore the nature and contents of the Frank-Mises, and discuss its complementary relationship to the first volume of the text that the mathematicians Richard Courant (1888 1972) and David Hilbert (1862 1943) published on the methods of mathematical physics in 1924, the Courant-Hilbert,which, when it and its second volume of 1937 were translated into English and extensively revised in 1953 and 1961, eclipsed the classic Frank-Mises.

The concept was extended (Brown-Séquard and it was suggested that brain lesions caused functional rupture in regions distant from the injured one ("action à distance". The term "diaschisis" (von Monakow, proposed as a new modality of shock, had its concept broadened, underpinned by observations of patients, aiming at distinguishing between symptoms of focal brain lesions and transitory effects they produced, attributable to depression of distant parts of the brain connected to the injured area. Presently, diaschisis is related mainly to cerebrovascular lesions and classified according to the connection fibers involved, as proposed by von Monakow. Depression of metabolism and blood flow in regions anatomically separated, but related by connections with the lesion, allows observing diaschisis with neuroimaging.

    The study considers the origins of Karl Jaspers' phenomenology. What did phenomenology mean to Jaspers and what was his personal perspective? What metaphors did he associate with it? This paper describes his phenomenological method by using the metaphors of histology and the X-ray. This perspective enables a better understanding, not only of the origins and essence of his phenomenology but also of its value for Jaspers himself. In Jaspers' daily life, he would have been familiar with microscopes and X-ray machines.

    2007-05-01

    Full Text Available Karl Barth saw in natural theology a threat to the church of Christ. He was convinced that the so-called “German Christians” under the influence of the National Socialist Party practised natural theology. He advocated the need for the church of Christ to be church according to the Word of God. The church can be true church of Christ when it listens to and obeys the true calling of God. Barth’s critique of an exclusive “Volkskirche” can serve as a corrective for the definition of the Nederduitsch Hervormde Kerk as a “volkskerk”.

    Jolissaint and Stalder introduced the definitions of mixing and weak mixing for von Neumann subalgebras of finite von Neumann algebras. In this paper, we study various algebraic and analytical properties of mixing and weakly mixing von Neumann subalgebras. We prove some basic results about mixing inclusions of von Neumann algebras and establish a connection between mixing properties and normalizers of von Neumann subalgebras. The special case of mixing subalgebras arising from inclusions of group von Neumann algebras finds applications to ergodic theory. For a finite von Neumann algebra $M$ and von Neumann subalgebras $A$, $B$ of $M$, we introduce a notion of weak mixing of $B\\subseteq M$ relative to $A$. If $B$ is abelian and $A\\subset B$, we show that weak mixing of $B \\subset M$ relative to $A$ is equivalent to the following property: if $x\\in M$ and $xAx^*\\subset B$ then $x\\in B$. In the general case, we show that weak mixing of $B\\subset M$ relative to $A$ is equivalent to the following property: if $x\\i...

  6. The psychology of thinking, animal psychology, and the young Karl Popper.

    Science.gov (United States)

    Ter Hark, Michel

    2004-01-01

    In the 1920s, Karl Popper wrote two large manuscripts on psychology that he never published. In his autobiography, Unended Quest, he attempts to reduce the importance of his work in psychology as much as possible, and in his philosophical work he is an antipsychologist. However, in this article, it is argued that Popper's early psychology has been pivotally important for the development of his philosophy. In particular, it is shown that Popper's views on psychology underwent a radical shift, one that paved the way for his characteristic deductive stance in philosophy. Popper's views shifted from an inductive and associationistic psychology toward a noninductive psychology of problem solving. Tracing the historical background of Popper's early work reveals how he integrated various parts of the psychology of Karl Groos into his analysis of the childish phenomenon of dogmatic thinking and how he shortly after appropriated various elements of the animal psychology of Hans Volkelt and Herbert Jennings in his biological approach to (dogmatic) thinking. In the monumental works of Otto Selz, however, Popper finally found the roots of a noninductive and biological approach to the growth of individual and scientific knowledge.

    Full Text Available DOI: http://dx.doi.org/10.5007/2175-8077.2012v14n32p124Karl Popper is the leading philosopher of science in modern times, competing with Thomas Kuhn’s interpretation to the primacy of how to utilize de scientific method. Clearly, there are different versions for a reading of this important author who coined the method called deductive with test. This text recognizes the relevance of Karl Popper’s view of science as a practice in hard and biological fields, where it is widely accepted. However, this popularity is not shared in the applied social sciences area. This is an essay to rescue his contribution in an attempt to translate the concepts he developed in a didactic way. To this end, there will be an introduction to the fundamentals of science as specific form o knowledge, seeking to contrast the deductive and inductive approaches and procedures of what is known as formal science, basic and applied. An attempt to classify the formulation of theoretical propositions is undertaken with the use of different criteria, taking examples in the field of management and economics as an illustration.

    Full Text Available In depicting a comprehensive religious world view, Karl Ristikivi’s series of historical novels is structured, like Dante’s Divine Comedy, according to the philosophy of the gothic cathedral. With characters, events and themes corresponding with Dante’s masterpiece, the novels form a tri-level structure based on Christian myths. The novels are delineated by associations with paradise (The Burning Flag, The Bridal Veil, Noble Hearts, purgatory (The Last Citadel, The Song of Joy, Dragon’s Teeth and hell (The Riders of Death, A Sorcerer’s Apprentice, Double Play. Contrary to the philosophy of increasing light found in Divine Comedy, Ristikivi’s historical series of novels portray the descent from light to darkness, from unity to fragmentation, from asceticism to sexuality, and from elevated language and style to comedy and grotesquery. In the first two trilogies, the characters’ ethical bearing steadily deteriorates. As well as comparisons to paradise and its inhabitants, a key theme of the paradise novels is the kingdom of Christ. The virtuous heroes of The Burning Flag and The Bridal Veil, Konradin von Hohenstaufen and St. Catherine of Siena, symbolize two aspects of the kingdom of Christ: the empire and the church. Both characters are also associated with the image of a mountain where salvation is at the top. The model for this is the Mount of Purgatory in Divine Comedy, which has earthly paradise at the top. In the purgatory novels, the characters and motifs are associated, as in Dante’s work, with the cultural sphere. These three novels are permeated with themes such as penitence, guilt and judgement. Brimming with inhumanity and discord, the hell novels feature themes related to the Tower of Babel and making a pact with the devil. Another of Ristikivi’s novels, the metaphysical All Souls’ Night also follows the structure of Divine Comedy and can therefore be regarded as part of the historical series. The world of All

  11. Shakespearean Thoughts as Statutes. Law and Literature in Karl Kraus Pensieri shakespeariani come leggi dello stato. Letteratura e diritto in Karl Kraus

    2012-04-01

    Full Text Available It is not possible to understand Karl Kraus, claims Walter Benjamin, without assuming that in the oeuvre of the Viennese writer "everything takes place in the sphere of law". In Kraus’s thought legal issues are strongly related to literature and language. His concept of law stems from a higher ideal of ‘justice’; justice is based on language and language has a strong ideal and prescriptive value. Through the use of quotation Kraus charges literature and journalism with betraying language, while on the other hand he charges law with betraying justice. This essay aims at demonstrating trough an interdisciplinary approach that Kraus did not only involve law issues in his literary writings, he also invested some literary works – especially Shakespeare’s plays – with a legal value. In Kraus’s thought Shakespeare is a symbol of consubstantiality between reality and literature, and an 'encyclopedia' providing eternally valid categories. As an ideal paradigm for the interpretation of reality, Shakespeare is the utopian background of Kraus’s reflection on language and justice, bearing witness to the indissolubility, in Kraus’s thought, of literature and law.   È impossibile comprendere alcunché di Karl Kraus, afferma Walter Benjamin, se non si capisce che nell’opera del grande scrittore viennese «tutto ha luogo nella sfera del diritto». In Kraus l’analisi delle questioni giuridiche è inscindibile dalla riflessione sulla letteratura e sul linguaggio. La disamina del diritto muove da un più alto ideale di giustizia fondato sulla lingua, e specularmente il linguaggio possiede una forte valenza ideale e prescrittivo-normativa. Attraverso l’uso della citazione Kraus mette sotto accusa letteratura e giornalismo in nome di un più alto ideale di lingua, mentre nei suoi scritti letterari mette sotto accusa il sistema del diritto in nome di un più alto ideale di giustizia. Scopo del presente saggio è dimostrare, utilizzando un

    Reich, H; Hollwich, F

    1984-06-01

    The von Hippel-Lindau syndrome is an autosomal dominant condition that comprises, apart from angiomas of the retina, the cerebellum, the spinal cord, and the cerebrum, also cystic and blastomatous dysplasias resulting from maldevelopment, namely cystic kidney and pancreas, hypernephroma, and pheochromocytoma. Early observers of the syndrome were the English neurologist John Hughlings Jackson (1872) and the German ophthalmologist Hugo Magnus (1874). The typical association of angiomas of the retina with the cerebellum was first described in 1905 by the Prague ophthalmologist Wilhelm Czermak, long before Lindau (1926). The fact that hypernephromas and pheochromocytomas may form parts of it characterizes the syndrome as a polyneoplastic hereditary disease and the sufferers as members of families at risk. Since the ophthalmologist is often the first to recognize this disease by direct inspection of the fundi, he is responsible for ensuring proper medical care for the affected person and his or her entire family.

By conducting a series of non-invasive studies, such as 3D inventory using terrestrial laser scanning (TLS), thermal imaging, georadar measurements (around and inside the tomb) and anthropological research of mummified remains as well - the complete dataset was collected. Through the integration of terrestrial (TLS) and airborne laser scanning (ALS) authors managed to analyse the surroundings of Fahrenheid pyriamid and influence of some objects (like trees) on the condition and visibility of the Pyramids in the landscape.

  17. [Medical anthropology in academies: on the criticism of natural science medicine exemplified by Viktor von Weizsäcker].

    Science.gov (United States)

    Schott, Heinz

    2014-01-01

    Viktor von Weizsäcker (1886-1957) founded his concept of medical anthropology as a clinician educated in internal medicine and neurology. He tried to broaden natural scientific medicine psychosomatically focussing on the "sick human". The natural scientific approach would exclude subjectivity, and therefore he propagated the "introduction of the subject' (Einführung des Subjekts) into the life sciences. His own sensory physiological experiments and Sigmund Freud's psychoanalysis inspired him essentially since the 1920s. In his main work Der Gestaltkreis (gestalt circle) published in 1940 he stressed the "entity of perceiving and moving" (Einheit von Wahrnehmen und Bewegen) in regard to relevant aspects of medicine. In 1932, Weizsäcker became a member of the Heidelberg Academy of Sciences, whose president he was from 1947 till 1949; 1942 he became a member of the Leopoldina. Primarily his merits as a neurologist were highly appreciated. His medical anthropology was not relevant for his election by the two academies. Nevertheless, there was a certain repudiation against the objectivistic and materialistic Weltanschauung within the scientific community. So, Paracelsus and Goethe were highly estimated as natural philosophical guides for own conceptions. This was especially evident for the circle around Wilhelm Troll and Karl Lothar Wolf in Halle, both members of the Leopoldina, who were fascinated by Goethe's concept of "Gestalt". Weizsäcker's lecture on "Gestalt und Zeit" in Halle in 1942 fitted in the concept of those natural scientists.

  11. Titanisierung von Implantatoberflächen

    Science.gov (United States)

    Zimmermann, Hanngörg; Heinlein, Markus; Guldner, Norbert W.

    Titan gilt seit Jahrzehnten als einer der wichtigsten Implantatwerkstoffe in der Medizin. Neben den guten mechanischen Eigenschaften (Leichtigkeit, hohe Festigkeit etc.), besitzen Titanimplantate vor allem eine hervorragende Körperverträglichkeit, so dass die Implantate optimal in den humanen Organismus integriert werden [1]. Ist jedoch aufgrund der Anforderungen an das Implantat eine hohe Flexibilität und/ oder Elastizität gefragt, so scheidet der Werkstoff Titan aufgrund seiner spröden und unflexiblen Materialeigenschaften aus. Die Folge ist der Einsatz von Implantatmaterialien, sowohl künstlichen als auch biologischen Ursprungs, welche nicht selten eine unzureichende Biokompatibilität aufweisen und somit zu Fremdköper- und immunologischen Reaktionen und Einkapselung des Implantates führen können. Die Erhöhung der Körperverträglichkeit, eine Adaption an das biologische Umfeld und eine hohe Biokompatibilität sind demzufolge die wichtigsten Eigenschaften bei der bedarfsgerechten Herstellung von Implantaten und Implantatoberflächen. Zur Gestaltung von innovativen, biokompatiblen Oberflächen stehen unterschiedliche technische Lösungsansätze zur Verfügung. Zum einen besteht die Möglichkeit, geeignete Oberflächeneigenschaften aus dem Grundmaterial selbst zu optimieren. Dies geschieht unter anderem durch Modifikation der Werkstoffoberflächen in Form von Texturierungen und Oberflächenrauhigkeiten. Zum anderen können die Oberflächeneigenschaften unabhängig von denen des Trägermaterials gestaltet werden. Durch Funktionalisierung der Oberflächen mit geeigneten Beschichtungen oder der Zugabe von Medikamenten (Drug Eluting) werden die Kunststoffimplantate dahingehend verändert, dass eine Steigerung der Körperakzeptanz erreicht wird. Die Titanbeschichtung von Implantatoberflächen kombiniert die positiven Materialeigenschaften von Titan und Polymer.

    Directory of Open Access Journals (Sweden)

    Roberto Carradore

    2013-07-01

    Full Text Available The present contribution aims at defining the relation between cybernetics and social theory from the perspective of society as order. After an historical framework of the cybernetic movement, a careful reading of the works of Norbert Wiener, in which he introduced the concept of feed-back and the idea of information society, has revealed a keen awareness about the social effects of technological innovation. Among the social scientists who had made use of cybernetic concepts, it has been considered the work of Karl Deutsch, which was one of the first completely cybernetic perspective for the study of political and social phenomena. The main conclusion is that cybernetics, as a meeting point between different disciplines, has produced an image of self-regulated society in line with the image of society as order.

To rise from the letters is a mutual influence on the interpretation of the key concepts that characterize the thought of the two authors, which however does not cancel the fundamental divergence of their political orientation.

  1. ["Homesickness and crime"--a contribution of Karl Jaspers to criminal psychology].

    Science.gov (United States)

    Bachhiesl, Sonja Maria

    2009-01-01

    Even a century after its first publication in "Archives of Criminology" (in German: Archiv für Kriminologie), the doctoral thesis of Karl Jaspers (1883-1969), which was newly edited in 1996, continues to be of interest. Although the crimes described by Jaspers, which took place in a rural area, do no longer occur in this form just as the rural culture itself has disappeared, this paper nevertheless contains reflections that may also be relevant for the interpretation of modern potentials of conflict and violence and crimes rooted therein. The former homesickness has developed into novel phenomena of uprooting. In both cases, problems of maladjustment are a contributing factor to crime motivation. Thus despite all terminological and methodological change, Jaspers' thesis is an example for the continuing relevance of certain subjects in criminological discourse.

  2. Investigation of amine-buffered amide reagents for coulometric Karl Fischer titration.

    2009-06-15

    Formamide (FA), N-methylformamide (NMF), and dimethylformamide (DMF), were evaluated as solvents for coulometric Karl Fischer (KF) reagents in combination with several amine bases. Except for the effect of the iodine species (iodine or triiodide), the pH of the reagent and the position of the sulfur dioxide/hydrogen sulfite equilibrium were found to be the main factors explaining the large difference in the observed reaction rates between water and the KF reagent in these solvents. Acid-base titrations showed that hydrogen sulfite is the main sulfur reactant in these media. The results will be of great importance in finding suitable combinations of base and solvent with respect to stoichiometry, side reactions caused by active carbonyl compounds, and reagent stability.

  3. Coulometric trace determination of water by using Karl Fischer reagent and potentiometric end-point detection.

    Science.gov (United States)

    Cedergren, A

    1974-06-01

    A new approach to the determination of water via the Karl Fischer reaction is described. Iodine is coulometrically generated and the end-point corresponding to a slight excess of iodine, is detected potentiometrically with a non-polarized platinum electrode. Samples of 1-500 mul containing 0.05-200 mug of water were analysed with a standard deviation of 0.015 mug in the range 0.05-20 mug of H(2)O. A specially constructed electrolysis cell was used in combination with an LKB 16300 Coulometric Analyzer and the time for a complete analysis was 1-4 min, depending on sample size. The reagent composition has been optimized in order to enhance the rate of the main reaction and to minimize the extent of side-reactions. Decreasing the temperature reduced the extent of side-reactions. The displacement of end-point potential on dilution was studied and a correction is discussed.

    2007-05-01

    Full Text Available Karl Barth’s hermeneutic legacy prolonged Western Christian tradition, especially influenced by Hegelian philosophy of history. This led to Barth’s “theological exegesis” instead of a historic-critical exegesis. In a preceding article Barth’s understanding of the notion “hermeneutic circle” is discussed against the background of the Enlightenment and its counter-movement in Romanticism. In this article Barth’s attitude to the place and role of historical criticism is explained in light of his dialectic distinction between “scientific” and “practical” interpretation. The article aims to show that Barth, with his dialectics, continues Schleiermacher’s realism. In conclusion, the positivistic traits in the Barth legacy are raised once again, in order to open the door to Jürgen Habermas and other deconstructionist thinkers of the postmodern era in hermeneutics.

    Full Text Available This article discusses about philosophy of science according to Karl R. Popper and Thomas S. Kuhn. There are similarities and differences between their views about how progress and what function of science.Apparently both Popper and Kuhn agree that science does not proceed by induction. However Kuhn disagrees with the view that science progresses by falsifiability through conjectures and refutations, but occurance by paradigm shift. Popper and Kuhn’s disagreement amounted to a distinction between two functions within the practice of science, one of criticism (Popper and one of puzzle solving (Kuhn.Science education implies the teaching and learning of science interesting and fruitful in one hand, and teachers should be role models to students in the other hand

  10. Vital forces and organization: philosophy of nature and biology in Karl Friedrich Kielmeyer.

    Gambarotto, Andrea

    2014-12-01

    The historical literature on German life science at the end of the 18th century has tried to rehabilitate eighteenth century vitalism by stressing its difference from Naturphilosophie. Focusing on the work of Karl Friedrich Kielmeyer this paper argues that these positions are based on a historiographical bias and that the clear-cut boundary between German vitalism and Naturphilosophie is historically unattested. On the contrary, they both belong to the process of conceptual genealogy that contributed to the project of a general biology. The latter emerged as the science concerned with the laws that regulate the organization of living nature as a whole. The focus on organization was, at least partially, the result of the debate surrounding the notion of "vital force", which originated in the mid-eighteenth century and caused a shift from a regulative to a constitutive understanding of teleology.

    The cerebral cortex displays substantial variation in cellular architecture, a regional patterning that has been of great interest to anatomists for centuries. In 1925, Constantin von Economo and George Koskinas published a detailed atlas of the human cerebral cortex, describing a cytoarchitectonic division of the cortical mantle into over 40 distinct areas. Von Economo and Koskinas accompanied their seminal work with large photomicrographic plates of their histological slides, together with tables containing for each described region detailed morphological layer-specific information on neuronal count, neuron size and thickness of the cortical mantle. Here, we aimed to make this legacy data accessible and relatable to in vivo neuroimaging data by constructing a digital Von Economo - Koskinas atlas compatible with the widely used FreeSurfer software suite. In this technical note we describe the procedures used for manual segmentation of the Von Economo - Koskinas atlas onto individual T1 scans and the subsequent construction of the digital atlas. We provide the files needed to run the atlas on new FreeSurfer data, together with some simple code of how to apply the atlas to T1 scans within the FreeSurfer software suite. The digital Von Economo - Koskinas atlas is easily applicable to modern day anatomical MRI data and is made publicly available online.

    Alloplastic materials are broadly used in modern surgery. Until the middle of the 20th century, metal materials and especially silver were used because of their antimicrobial properties. With the development of a new catalytic process for the production of high-density polyethylene and polypropylene materials, a new era of prosthesis was introduced. These polymers are integral part of our everyday operations surgery, especially in hernia repair. The famous surgeon Billroth mentioned to his pupil Czerny in 1878: "If we could artificially produce tissues of the density and toughness of fascia and tendon, the secret of the radical cure of hernia would be discovered". The polypropylene developed by Karl Ziegler gave the surgeon a material for daily practice, which in its properties (nearly) achieved Billroth's initial vision. In 1963 the Nobel Prize for Chemistry was awarded to Karl Ziegler and Giulio Natta in Stockholm. Furthermore, August 11, 2013 will be the 40th anniversary of Karl Ziegler's death. This manuscript honors both days.

    Prins Karls Forland, Svalbard, comprises a fold-thrust belt as a result of the Eocene Eurekan orogeny. The northern part of the island (north of Selvågen) is dominated by Neoproterozoic siliciclastic metasediments regionally metamorphosed to greenschist facies conditions, probably in association with one distinct stage of Caledonian tectonism. Contrasting with these low grade sequences are rocks of the Pinkie Unit, which are locally exposed along east coast of Prins Karls Forland. Amphibolite facies metasediments show evidence for at least two distinct deformation stages (including mylonitization). All the borders of the Pinkie unit are tectonic: to the east, it is a sharp boundary with the truncation of the Pinkie foliation into a N-S fault, parallel to the coast, probably associated with the formation of the Neogene Forlandsundet Graben. A ~1 km wide ductile to brittle shear zone (the Bouréefjellet shear zone) separates the low and high grade sequences along the western margin, with the Grampian Formation (low metamorphic grade quartzites, conglomerates, siltstones and slates) as the upper structural unit. Moreover, the shear zone contains outcrops of metagabbro associated with magnetite ore (Maraszewska et al. 2016, EGU). The apparent tectonostratigraphy of the Pinkie unit consists of laminated fine-grained calc-silicate rocks, locally with scapolite, and a strong E-W lineation at lower structural levels. In these rocks primary layering is apparent (S0) and parallel to metamorphic foliation plane (S1). Interconnected elongated mica crystals within S1 are deformed by C'-type shear zones. They are overlain by garnet-bearing quartzite-mylonites and garnet-bearing mylonitic mica schists with N-S to NW-SE lineations at upper structural levels. Kośmińska et al. (2015a, Mineralogia - Special Papers, vol. 44, 61-62) determined P-T metamorphic conditions of garnet-mica schist of 7-9 kbar and 550-650°C.

    Eurekan deformation has been proven to be a complex sequence of tectonic episodes, dominated by compression in the Circum Arctic region. It was associated with early Cenozoic collision of Eurasia, North America and Greenland plates producing fold-thrust belt style of deformation. Timing of this enigmatic event has not yet been extensively resolved by radiometric dating (Piepjohn et al. 2016, Journal of the Geological Society, 173(6), 1007-1024). Reinhardt et al. (2013, Z. Dt. Ges. Geowiss., 164 (1), 131-147) dated syn-tectonic volcanic ashes at c. 60 Ma and 54 Ma on Ellesmere Island, Canada. Tagner et al. (2011, Earth and Planetary Science Letters, 303(3), 203-214) interpreted c. 49-47 Ma 40Ar/39Ar ages on trachyte flows in northern Greenland as peak compression during the Eurekan event. On Svalbard, Tessensohn et al. (2001, Geologisches Jahrbuch, B 91, 83-104) reported K/Ar whole rock ages ranging from c. 67 to 49 Ma for the slates from Svartfjella-Eidembukta-Daudmannsodden Lineament. Bentonite layers in the Central Tertiary Basin are as young as c. 56 Ma (Charles et al. 2011, Geochem. Geophys. Geosyst., 12, 1-19), predating latest deformation. Moreover, Barnes et al (2017, in prep.) applied (U-Th)/He thermochronology along the western margin of Svalbard and resolved Early to Middle Eocene heating, likely documenting burial related to thrusting. Here we present new results from 40Ar/39Ar muscovite dating of ductile to brittle shear zone on Prins Karls Forland, Svalbard, indicating Eurekan age of thrusting. Prins Karls Forland is dominated by Neoproterozoic siliciclastic metasediments (comprising Caledonian basement) regionally metamorphosed to greenschist facies conditions. A ˜1 km wide ductile to brittle shear zone (the Bouréefjellet shear zone) separates the amphibolite facies Pinkie Unit from the lower grade upper structural unit, the Grampianfjella Formation (Faehnrich et al. 2016, EGU 2016).

    2014-01-01

    The Potassium-Argon Laser Experiment( KArLE), is composed of two main instruments: a spectrometer as part of the Laser-Induced Breakdown Spectroscopy (LIBS) method and a Mass Spectrometer (MS). The LIBS laser ablates a sample and creates a plasma cloud, generating a pit in the sample. The LIBS plasma is measured for K abundance in weight percent and the released gas is measured using the MS, which calculates Ar abundance in mols. To relate the K and Ar measurements, total mass of the ablated sample is needed but can be difficult to directly measure. Instead, density and volume are used to calculate mass, where density is calculated based on the elemental composition of the rock (from the emission spectrum) and volume is determined by pit morphology. This study aims to reduce the uncertainty for KArLE by analyzing pit volume relationships in several analog materials and comparing methods of pit volume measurements and their associated uncertainties.

    2012-01-01

    The point of the article is to analyse and reflect on certain symptoms of anorexia nervosa in light of Karl Jaspers and Erich Fromm's ideas and social constructivism. Contemplating the disorder in view of the philosophical ideas mentioned earlier, the author analyses such aspects of patients as: functioning on the verge of life and death, the paradoxical struggle to escape from freedom in search of independence, as well as various understandings and descriptions of anorexia in consideration of social constructivism. The author shares thoughts and poses hypotheses, trying to view anorexia in light of selected philosophical and psychological ideas, which in their general assumptions were not concerned with defining nor analysing anorexia nervosa. In view of Karl Jaspers' ideas, the author focuses on the so called 'limit-situations', in the ideas of Erich Fromm she takes notice in "Escape from Freedom" to new relations. Finally in the light of social constructivism the author focuses on the cultural context.

    The understanding, occasionally recognized, that Sigmund Freud had the intuition to use cocaine as local anesthetic for surgical procedures, or even that he played any role in the discovery of local anesthesia is not true. The objective of Freud's studies were different, and based in irrefutable evidence, Karl Köller was the real inventor of local anesthesia. In face of those facts, proper knowledge of this historically important subject is due. This report refers to the long-known properties of cocaine. It also remembers personal data, and the professional and scientific activities of Sigmund Freud and Karl Köller. It presents Freud's researches on the pathophysiological effects of cocaine. It exposes the reasons for the harsh criticism of Freud's concepts. It describes the sudden, but conscious and justified, idea of Karl Köller to study scientifically the use of cocaine as a local anesthetic in animals and humans. It indicates how those pioneering studies, that culminated with the discovery of local anesthesia by Köller and two presentations in Vienna on the subject, were done. It also reports the first ophthalmologic surgery under local anesthesia. It shows the immediate dissemination throughout the world of the discovery that marked the beginning of regional blocks. It comments several documents corroborating the role of Köller in this discovery. And, finally, it mentions the numerous homages received by Köller in different areas of the world. COCLUSIONS: Regional block was introduced by Karl Köller in 1884, when he demonstrated the feasibility of performing painless ophthalmologic surgeries by using cocaine as a local anesthetic. Sigmund Freud studied cocaine extensively, but he did not have direct participation in this important discovery.

    Jakowski, Jacek; Morokuma, Keiji

    2009-06-01

    We present a novel first principles molecular dynamics scheme, called Liouville-von Neumann molecular dynamics, based on Liouville-von Neumann equation for density matrices propagation and Magnus expansion of the time-evolution operator. The scheme combines formally accurate quantum propagation of electrons represented via density matrices and a classical propagation of nuclei. The method requires a few iterations per each time step where the Fock operator is formed and von Neumann equation is integrated. The algorithm (a) is free of constraint and fictitious parameters, (b) avoids diagonalization of the Fock operator, and (c) can be used in the case of fractional occupation as in metallic systems. The algorithm is very stable, and has a very good conservation of energy even in cases when a good quality conventional Born-Oppenheimer molecular dynamics trajectories is difficult to obtain. Test simulations include initial phase of fullerene formation from gaseous C2 and retinal system.

    One formulation of D. Voiculescu's theorem on approximate unitary equivalence is that two unital representations π and ρ of a separable C*-algebra are approximately unitarily equivalent if and only if rank o π = rank o ρ. We study the analog when the ranges of π and ρ are contained in a von Neumann algebra R, the unitaries inducing the approximate equivalence must come from R, and "rank" is replaced with "R-rank" (defined as the Murray-von Neumann equivalence of the range projection).

Sjögren studied medicine at the University of Uppsala. From 1932 to 1935, he was Head Physician and Director of Lillehagen Hospital in Gothenburg, and between 1935- 1945, he was physician-in-chief at the psychiatric department of Sahlgrenska Hospital in Gothenburg. Sjögren was professor of psychiatry at Karolinska Institutet from 1945 to 1961 and was elected to the Royal Swedish Academy of Sciences in 1951. Sjögren was an expert of psychiatry for the World Health Organization. Among his many contributions to medicine, he is credited for describing several medical conditions, which were later named after him, including Graefe- Sjögren syndrome, Marinesco-Sjögren syndrome, and Sjögren-Larsson syndrome (SLS. During his work on juvenile amaurotic idiocy, Sjögren forged a collaboration with Tage K.L. Larsson, a statistics lecturer at the University of Lund. Their study on the combination of oligophrenia, congenital ichthyosis, and spastic disorders in 1957 established the clinical and genetic profile of a new disease entity, later known as Sjogren-Larsson syndrome (SLS.

    2013-11-01

    With his "Allgemeine Psychopathologie" (general psychopathology) published in 1913, Karl Jaspers laid a comprehensive methodological and systematic foundation in psychiatry. Following Edmund Husserl, the founder of philosophical phenomenology, Jaspers introduced "static understanding" into psychopathology, i.e. the unprejudiced reproduction of conscious phenomena. From the philosopher Wilhelm Dilthey he further adopted the distinction between causal understanding as a means of accessing nature and pathological processes and hermeneutic understanding, also called genetic understanding, as a way of accessing mental phenomena. The intrusion of an event that is incomprehensible in terms of an understandable development is seen as indicating an extraconscious phenomenon or transition to a somatic process. Jaspers opted for philosophy early in his life. After quitting law studies he graduated in medicine, arrived in psychopathology without any psychiatric training, to psychology without ever studying psychology and to a chair in philosophy without a degree in philosophy. Despite believing himself to be chronically ill and to die early, Jaspers produced a life’s work almost immeasurable in scope. He died in 1969 aged 86 years.

    The broad spectral bandwidth at mm and cm-wavelengths provided by the recent upgrades to the Karl G. Jansky Very Large Array (VLA) has made it possible to conduct unbiased searches for molecular CO line emission at redshifts, z > 1.31. We present the discovery of a gas-rich, star-forming galaxy at z = 2.48, through the detection of CO(1-0) line emission in the COLDz survey, through a sensitive, Ka-band (31 to 39 GHz) VLA survey of a 6.5 square arcminute region of the COSMOS field. We argue that the broad line (FWHM ~570 +/- 80 km/s) is most likely to be CO(1-0) at z=2.48, as the integrated emission is spatially coincident with an infrared-detected galaxy with a photometric redshift estimate of z = 3.2 +/- 0.4. The CO(1-0) line luminosity is L'_CO = (2.2 +/- 0.3) x 10^{10} K km/s pc^2, suggesting a cold molecular gas mass of M_gas ~ (2 - 8)x10^{10}M_solar depending on the assumed value of the molecular gas mass to CO luminosity ratio alpha_CO.

    Full Text Available The aim of this study is to present Albert Camus’ and Karl Jaspers’ interpretations of Ivan Karamazov’s rebellion as the diagnoses of the weakness of the human intellect in confrontation with the world and the criticism of rationalism. Therefore, in the introduction I will present those fragments of the novel that characterize Ivan’s rebellion as highly abstract and theoretical. At the same time, this common literary context serves as the ground for reconstruction and comparison of the basic philosophical assumptions of each author. The intention of the remaining part of the paper is, firstly, to reconstruct A. Camus’ and K. Jaspers’ epistemology and, secondly, to analyse the arguments against Ivan’s attitude formulated by the writers. Their criticisms of the protagonist’s excessive trust in intellect is based on their own concepts of human epistemic capacity, which are related to the problems of the absurd in A. Camus’ and transcendence in K. Jaspers’ writings. The question of nihilism demands analysis of A. Camus’ idea of the nature of rebellion as both affirmative and negative, and of K. Jaspers’ notion of faith as pre-intellectual trust. Finally, their criticisms of the slogan “If there is no God, then anything is allowed” introduces the problem of freedom, which allows the comparison of the concepts of solidarity (A. Camus and communication (K. Jaspers. In the conclusion these two philosophical attitudes are discussed together. Keywords: ; ; ; ; ; ; ; ;

    Directory of Open Access Journals (Sweden)

    Inge van de Ven

    2016-06-01

    Full Text Available This article analyzes Karl Ove Knausgård’s six-volume autobiography My Struggle in the frame of an emerging cross-medial aesthetics of the ‘serial self’. This aesthetics is informed by the technological potentialities of digital media, and by social media practices like taking a selfie or posting a blog every single day and accumulating these self-representations, without selection. The serial self is marked by continuity, real-time effects, open-endedness, rhythm, repetition, and a thematic attention to the mundane. It can be discerned in the daily comic strip, the daily selfie, and time-lapse cinema. The article embeds My Struggle in this larger, intermedial framework. Moreover, it refers to the work of psychologist Galen Strawson to argue that the self-representations in Knausgård’s work should be understood as episodic rather than diachronic in nature. This results in a sequential and paratactic, rather than causal and hierarchical, presentation of memorial material. It is claimed that serial self-representations of this type are increasingly central to our current media ecology. They offer a valuable medium for investigating, materializing, and mapping on the page the traces left by the passage of time, as serialization lends itself to performative and cumulative representations of a ‘self’ in flux, that dramatize and perform the struggles of the episodic personality in search for continuity.

    Rheumatoid arthritis is a crippling and disabling joint disease affecting over 20 million people. It occurs predominantly in women and smokers, and affects the HLA-DR1/4 individuals who carry the "shared epitope" of amino acids EQRRAA. The cause of this disease was investigated by the methods of the philosopher of science Karl Popper who suggested that scientific research should be based on bold conjectures and critical refutations. The "Popper sequences" generate new facts which then change or alter the original problem. The new facts must then be explained by any new theory. Using the "molecular mimicry" model, it was found that Proteus bacteria possess an amino acid sequence ESRRAL in haemolysin which resembles the, shared epitope, and another sequence in urease which resembles type XI collagen. Antibodies to Proteus bacteria have been found in 14 different countries. It would appear that rheumatoid arthritis is caused by an upper urinary tract infection by Proteus bacteria. Anti-Proteus therapy should be assessed in the management of this disease separately or in conjunction with existing modalities of therapy.

    2009-12-01

    September 17th, 2009 marks the 15th anniversary of Sir Karl Popper's death. Popper was an outspoken champion of critical rationalism, and a constant critic of authoritarian tendencies in science and society. He was also one of the spiritual founders of this journal and served on its first editorial advisory board. Popper was recognized around the world as one of the 20th century's greatest philosophers of science and one of its most articulate and influential critics of Marxism and closed society. When he died, the contemporary wisdom among professional philosophers was that his philosophy was generally right-but somehow obsolete. Some commentators said that it was now obvious that scientific theories cannot be shown to be true. Others said that we had witnessed the end of history and that his critique of closed societies, while no doubt important in its day, had been fully assimilated into Western thinking and still had meaning, if at all, only for the democracies in transition that were trying to emerge from the former Soviet Union. But 15 years after his death, a look at science and society around the world gives us good reason to remember his philosophy.

  15. [Note on the epistemology of clinical pharmacology: comparison with the approach of Karl Popper].

    Science.gov (United States)

    Boissel, J P

    1999-01-01

    Is clinical pharmacology a science or only an application of science? Karl Popper suggested a method to identify science and to sort it out from other logical activities such as metaphysics, whereby the falsification criterion he proposed can apply to the theory in such a way that the theory could be refuted. The clinical pharmacologist's approach requires the build-up of a therapeutic model on the basis of two other models: the physiopathologic and the pharmacological. The three-model construct is a theory. Is it scientific in the Popperian sense? From the therapeutic model, one can predict the efficacy of a drug, and the corresponding statement is tested by a clinical trial. Whatever the original statement, it is modified into a refutable one because of the use of the statistical approach in clinical trials. Furthermore, the predicate represents a hypothesis of the model validity, which will then be confronted with 'reality' through clinical experiment. As the therapeutic model is refutable, clinical pharmacology is a science in the Popperian sense.

In 1961, during the Congress of the German Society of Sociology, two great theoretical references of the XX century faced in a historical debate about the logic of the social sciences. In addition to methodological issues strict sense, the confrontation became known as a debate between positivism and dialectic. The article first deals with the theoretical trajectories of Popper and Adorno and the relation of their theories with their political and ideological certainties. On one hand, the trajectory of the Popperian epistemology is examined, its contributions and vigorous attacks on Marx in what he called 'poverty of historicism" and false predictive Marxist world, and, on the other hand, the role of Adorno in the Frankfurt School, his criticism of totalitarianism and the defense of a critical emancipatory reason. The article also deals with the confrontation itself, the exposure of Popper's twenty-seven theses that culminate with the situation logic and the method of the economy as exemplary for the social sciences and Adorno's critical perspective of sociology and society as non-separable objects. In conclusion we show how the articulation of theory with the weltanschauung of each author helps to clarify the terms of the debate and how the confrontation contributed unequivocally to the dynamics of scientific progress and for the critical history of the ideas.

    Full Text Available Sir Karl Popper (1902-1994, though not trained as a physicist and embarrassed early in his career by a physics error pointed out by Einstein and Bohr, ultimately made substantial contributions to the interpretation of quantum mechanics. As was often the case, Popper initially formulated his position by criticizing the views of others - in this case Niels Bohr and Werner Heisenberg. Underlying Popper's criticism was his belief that, first, the Copenhagen interpretation of quantum mechanics abandoned scientific realism and second, the assertion that quantum theory was complete (an assertion rejected by Einstein among others amounted to an unfalsifiable claim. Popper insisted that the most basic predictions of quantum mechanics should continue to be tested, with an eye towards falsification rather than mere adding of decimal places to confirmatory experiments. His persistent attacks on the Copenhagen interpretation were aimed not at the uncertainty principle itself and the formalism from which it was derived, but at the acceptance by physicists of an unclear epistemology and ontology that left critical questions unanswered.Quanta 2012; 1: 1–12.

    Different procedures based on the Karl Fischer reaction were investigated with respect to their applicability for water determinations in environmental hydraulic fluids:  (i) continuous coulometry using a recently described diaphragm-free cell; (ii) on-line stripping of water at elevated temperature using either continuous coulometry or direct potentiometry for detection of the liberated water. Except for one of the oils, Statoil PA, which is a poly(α-olefin) with certain polymers added, no significant difference was found among coulometry using an optimized imidazole-buffered methanolic reagent containing 75% (v/v) chloroform, the two different stripping techniques (working in the temperature interval 100-110 °C), and the commercially available Hydranal Coulomat AG-H. The high stability and sensitivity of the coulometric technique described made it possible to work with sample amounts in the low milligram-range, and this is shown to increase the reliability of the coulometric method as compared to normally used procedures.

    Factors influencing the accuracy of water determinations using diaphragm-free, pulsed current Karl Fischer (KF) coulometry were investigated with the new Metrohm 756 instrument. Results obtained with commercially available reagents from Riedel-deHaen and Merck were compared with home-made ones that were especially designed to minimize the formation of iodine-consuming reduction products generated in the cathode reaction. Positive errors in the range 2-5% were found for the commercial reagents as compared to 0.2-1% for the home-made ones which were buffered at about pH 10 containing modifiers like chloroform, hexanol or ethylene glycol. Except for the composition of the KF-reagent, the cathode current density and the titration rate were found to be critical parameters for the accuracy of the determinations. For all reagents investigated, the best results were obtained for the maximum generator current 400 mA (corresponding to a current density of 1,400 mA cm(-2)) in combination with a maximum titration rate of 2,000 microg min(-1). Surprisingly, the errors found under optimum conditions for the pulse technique were always somewhat larger than the corresponding values obtained with continuous coulometry.

The author compares the block of philosophical and theological topics such as the theory of temporality, dialectic concept of the beginning (Ursprung and other types in philosophical discourses used by K. Barth (platonism, neo-Kantianism, existentialism, scholasticism, phenomenological philosophy and others with theology of K. Barth. The article gives a brief reconstruction of the theology of God’s Word by K. Barth in its two complementary projections as presented in the ‘Sketch of Christian Doctrine’ and ‘Dogma of the Church’. During the presentation the reader is well acquainted with the third projection of the concept of God’s Word by K. Barth at the time of the genesis of the book ‘Fides quaerens intellectum’. The article tests the hypothesis that the second edition of the ‘Romans’, ‘Fides quaerens intellectum’ and ‘Sketch of the Christian Dogma’ with ‘Church Dogma’ explicate the form of Christian theology, which, absorbing primarily the important philosophic achievements of 19–20th centuries, yet tries to stay free of them. Using various forms of philosophical discourses Karl Barth implements his own task of building a Christian theology beyond metaphysics, history and human existence.

    In 1968, Karl Menninger, a highly visible and vocal U.S. psychiatrist, published a call to action on prison reform, The Crime of Punishment (Menninger, 1966/1968). This widely circulated book's central idea is that punishment as practiced in penal settings is an injustice amounting to a crime. At the outset, The Crime of Punishment quickly achieved national attention. Within mainstream psychology, its antipunishment message encountered a changed climate in which punishment, thought ineffective during the period 1930 through 1960, was redefined as an effective component in learning. It also met competition from the contemporaneous Stanford Prison Experiment (Haney, Banks, & Zimbardo, 1973), which quickly rose to equivalent media presence and superior disciplinary prominence. Both the Stanford Prison Experiment and The Crime of Punishment survived in the antireform era of hyperincarceration after 1974 as parallel examples of reform activism, one secular and one religious in character, illustrating some convergences of aim between psychology and psychiatry outside of specifically clinical issues.

    Full Text Available Karl Barth’s gender perspective is often analysed with reference to his so-called “theoethics” or “creational theology”. This perspective perpetuates an asymmetry in gender relations that was prevalent in Biblical times, throughout Christianity and to some extent still is visible today. He based his view on the subordination of women on an exegesis of Genesis 1:27 as “intertext” of Ephesians 5:22-23. Barth’s asymmetrical gender perspective is a product of his embedment in Western Christian tradition which in turn, is rooted in early Christian patriarchal theology. The aim of this article is to focus on Barth’s ontological reframing of the traditional understanding of the Biblical notion of human beings as created in the “image of God”. The article consists of four sections: (a Luther’s and Calvin’s gender perspectives; (b the Enlightenment failure to achieve emancipation; (c gender disparity in Reformed theology; and (d a feminist alternative.

The existence of these phases in soils might have influence in redox processes, and they were considered as a possible water reservoir in Martian soils. In this study, we have used for the first time the Karl Fischer titration method to determine the amount of water released after heating several synthetic samples of goethite, hematite and natural iron ores at 105, 400, 600 and 900 °C. It was found that heating at 105 °C did not remove all moisture from the samples, and higher temperatures were necessary to completely remove all the absorbed water. The water contents determined at 400, 600 and 900 °C were found to be the same within the experimental errors, suggesting the inexistence of both protohematite and hydrohematite in the investigated samples. Therefore, the above-mentioned effects of these phases in soils might have to be reevaluated.

    Full Text Available In 1912 Josef Strzygowski founded the ‘Section for East Asian Art History’ at the University of Vienna, which attracted many students who would continue their careers in museums and at universities and thus established East Asian art history as an academic field. This paper examines these early art historical engagements with East Asian art: First, I discuss the role of East Asian art in Strzygowski’s agenda of broadening art history’s geographical scope beyond Europe and in his argument about the dominance of ‘Nordic’ artistic traditions in Europe and in Asia. Secondly, I introduce the work of two early students at the ‘Section for East Asian Art History’ in Vienna, Karl With and Alfred Salmony. Their respective approaches to East Asian art exemplify a range of methodological concerns of their time, from stylistic narratives, the concept of ars una, comparative frameworks, to ideas about cultural or national ‘purity’ in the arts, and an interest in cross-cultural adaption and transformation of motifs and symbolism.

    We compared the efficacy of Karl Storz CMAC Tip™ with inline suction to CMAC with traditional suction device in cadaveric models simulating difficult airways, using media mimicking pulmonary edema and vomit. This was a prospective, cohort study in which we invited emergency medicine faculty and residents to participate. Each participant intubated 2 cadavers (one with simulated pulmonary edema and one with simulated vomit), using CMAC with inline suction and CMAC with traditional suction. Thirty emergency medicine providers performed 4 total intubations each in a crossover trial comparing the CMAC with inline suction and CMAC with traditional suction. Two intubations were performed with simulated vomit and two with simulated pulmonary edema. The primary outcome was time to successful intubation; and the secondary outcome was proportion of successful intubation. The median time to successful intubation using the CMAC with inline suction versus traditional suction in the pulmonary edema group was 29s and 30s respectively (p=0.54). In the vomit simulation, the median time to successful intubation was 40s using the CMAC with inline suction and 41s using the CMAC with traditional suction (p=0.70). There were no significant differences in time to successful intubation between the 2 devices. Similarly, the proportions of successful intubation were also not statistically significant between the 2 devices. The proportions of successful intubations using the inline suction were 96.7% and 73.3%, for the pulmonary edema and vomit groups, respectively. Additionally using the handheld suction device, the proportions for the pulmonary edema and vomit group were 100% and 66.7%, respectively. CMAC with inline suction was no different than CMAC with traditional suction and was associated with no statistically significant differences in median time to intubation or proportion of successful intubations.

    Prins Karls Forland (PKF) is a N-S elongated island situated west of Spitsbergen in the Svalbard archipelago, High Arctic. The northern part of the island is dominated by siliciclastic metasediments regionally metamorphosed to greenshist facies assemblages during one distinct stage of tectonism. Amphibolite facies garnet-mica schists, mica schists, quartzites and carbonate-silicate rocks exhibiting evidence of at least two distinct, strong deformation episodes (including mylonitization) locally outcrop on the east coast of PKF, termed the Pinkie Unit. A ~1 km wide shear zone containing ductile to brittle structures and distinct outcrops of greenstones (metagabbros and greenschists), associated with magnetite ore, separates these two contrasting tectonic units. Ten samples of greenstones were collected on the slopes of Lauratzonfjellet and Boureefjellet for petrologic and geochemical analyses. Despite intense localized shearing, the metagabbros are undeformed and preserve coarse crystalline, magmatic texture, which is locally poikilitic. The primary magmatic assemblage consists of brown hornblende, plagioclase, biotite and opaque minerals, with accessory apatite and titanite. No relicts of pyroxenes are preserved. Formation of secondary uralite, sericite and chlorite is observed. Metamorphic assemblage consists of actinolite pseudomorhs after hornblende, epidote, and second generation biotite. Blue amphibole is observed in one sample from Boureefjellet; greenschists from Boureefjellet also contain fibrous blue amphibole, as well as garnets, actinolite, epidote and biotite. Some rocks sampled on Boureefjellet are more strongly deformed and exhibit probably two stages of metamorphism: amphibolite facies metamorphism resulting in blue amphibole-garnet assemblage followed by greenschist facies metamorphism resulting in actinolite-epidote-biotite paragenesis. Parallel and overlapping patterns on chondrite-normalized REE diagrams and spider diagrams indicate that these

  11. Karl Abraham, Sigmund Freud, and the fate of the seduction theory.

    Even after Freud had turned his attention away from the seduction theory of neurosogenesis, his close pupil and colleague, Karl Abraham, initially sought to investigate child sexual trauma further. In two of the very first articles on child sexual molestation, Abraham proposed that sexual abuse was particularly common among neurotic and psychotic patients as a result of a "traumatophilic diathesis," a trauma-related conceptual precursor of the repetition compulsion. In their correspondence, Freud trenchantly criticized many aspects of Abraham's papers on the subject of sexual trauma, in contrast to his public endorsement of Abraham's work in this area. For largely transferential reasons that this paper attempts to elucidate, Abraham did not encourage dialogue regarding persistent questions on the seduction issue, ceased publishing on that topic, and for some time controlled his apparently deep rankle over Freud's criticisms and failure to acknowledge Abraham's contribution to the concept of the repetition compulsion. Despite their close friendship and shared intellectual enthusiasm, Freud's response to Abraham's 1907 papers, as well as Abraham's almost uniformly positive disposition toward Freud, apparently prevented Abraham from further developing his observations and ideas on seduction and also lent background to their later clash. Subsequently, there was virtually no further psychoanalytic investigation of the subject of child sexual abuse until the issue arose briefly with Ferenczi in the early 1930s, and only occasionally after that for the next fifty years. The death of Abraham, and then Ferenczi, shortly after disputes with Freud may be among the factors that had an inhibiting effect on an earlier reconsideration of the seduction theory by others. Abraham's previously unheralded concept of traumatophilia has relevance to current clinical controversy regarding constitution and sexual trauma.

  12. Conditions for accurate Karl Fischer coulometry using diaphragm-free cells.

    2000-01-01

    Factors influencing the extent of formation of oxidizable reduction products in coulometric cells used for Karl Fischer (KF) determination of water were investigated. For methanolic KF reagents buffered with imidazole (Im) or diethanolamine (DEA) (separately or in combination), three parameters were found to be of outmost importance: the cathodic current density, the pH, and the concentration of protonated base (ImH+ or DEAH+). For reagents buffered with only Im, the relative formation of oxidizable reduction products varied in the range 2-40%; i.e., 51-70 micrograms of water was found for a 50 micrograms water sample, depending on the above-mentioned parameters. The lowest values were observed for reagents having a pH around 10 in combination with cathodic current densities in the range 2000-5000 mA cm-2. For all the Imbuffered reagents investigated, the addition of modifiers such as chloroform, hexanol, and carbon tetrachloride was found to decrease the formation of oxidizable reduction products significantly. For example, a reagent buffered at pH 10 containing 1 M hexanol gave less than 0.3% formation in the current density interval from 200 to 4000 mA cm-2. The best reagents based on the above-mentioned modifiers were tested in the continuous coulometric mode with errors typically in the interval 0-0.5% using optimum conditions. One prerequisite for obtaining such small errors with diaphragm-free continuous coulometry is to use a cathode area no larger than 0.002 cm2. For some of the reagents based on both Im and DEA, the formation of oxidizable reduction products was close to zero at certain current densities, although the analytical performance was not as good as for the reagents buffered solely by Im due to longer conditioning and titration times.

    Most of us see the organizations we operate in--our schools or companies, for instance--as monolithic and predictable, subjecting us to deadening routines and demanding dehumanizing conformity. But companies are more unpredictable and more alive than we imagine, according to Karl Weick, a psychology professor at the University of Michigan and an expert on organizational behavior. Weick says executives can learn a lot about managing the unexpected from organizations that can't afford surprises in the workplace--nuclear plants, firefighting units, or emergency rooms, for instance. In this conversation with HBR senior editor Diane Coutu, Weick examines the characteristics of these high-reliability organizations (HROs) and suggests ways that other organizations can implement their practices and philosophies. The key difference between high-reliability organizations and other companies is the mindfulness with which people in most HROs react to even very weak signs that some kind of change or danger is approaching. For instance, nuclear-plant workers Weick has studied immediately readjust dials and system commands when an automated system doesn't respond as expected. Weick contrasts this with Ford's inability to pick up on weak signs in the 1970s that there were lethal problems with the design of the Pinto gas tank. HROs are fixated on failure. They eschew plans and blueprints, looking instead for the details that might be missing. And they refuse to simplify reality, Weick says. Indeed, by cultivating broad work experiences and enlarging their repertoires, generalist executives can avoid getting paralyzed by "cosmology episodes"--events that make people feel as though the universe is no longer a rational, orderly system.

Al cabo de diez semestres de arduo trabajo, el resultado es una interpretación novedosa de las cuatro redacciones de El Capital. En efecto, ante los ojos de Dussel la obra maestra de Karl Marx se revela no solo como un tratado de economía sino antes bien como uno de antropología y ética. Marx, afirma Dussel, "deconstruye la economía capitalista críticamente y la reconstruye antropológica y éticamente". Asimismo, Dussel descubre que la producción teórica de Marx quedó inconclusa y, sobre todo, abierta a futuros desarrollos. Para el filósofo mendocino es necesario, en nuestro tiempo, no solo reinterpretar la totalidad de la obra de Marx sino también continuar su labor teórica, en especial desde América Latina, para el estudio del capitalismo periférico latinoamericano. Nuestro interés es indicar aquellos elementos que constituyen lo novedoso en la interpretación dusseliana de la obra teórica de Marx.From his exile in Mexico in the mid seventies of last century, Enrique Dussel is given the task of "reading seriously and directly" the theoretical work of Karl Marx produced between 1857 and 1882.

Indeed, in the eyes of Dussel, the masterpiece of Karl Marx is revealed not only as an economic treatise but rather as an anthropology and ethics. Marx "capitalist economy critically deconstructs and reconstructs anthropological and ethically". Moreover, Dussel finds that the theoretical yield of Marx was inconclusive and, above all, open to future developments. For the philosopher is needed in our time, not only reinterpret the whole work of Marx but also to continue his theoretical work, especially from Latin

    Full Text Available In the mid-nineteenth century Franz Kugler and Karl Schnaase decisively shaped the conception of art history as a discipline. Both explored connections between art of former epochs and that of the present. They understood the art of their day to be the result of a tradition of modernity based on the Renaissance and pointing into the future. Schnaase took an evolutionistic view similar to that of the architect Gottfried Semper: both advised against planning a programmatic new style. For Semper, the potential of new developments lay in the continuation of design patterns inherited from the earliest humans.

    Von Neumann's procedure is applied for quantization of General Relativity. We quantize the initial data of dynamical variables at the Planck epoch, where the Hubble parameter coincides with the Planck mass. These initial data are defined via the Fock simplex in the tangent Minkowskian space-time, the Dirac conformal interval. The Einstein cosmological principle is applied for the average of the spatial metric determinant logarithm over the spatial volume of the visible Universe. We derive the splitting of the general coordinate transformations into the diffeomorphisms (as the object of the second Noether theorem) and the initial data transformations (as objects of the first Noether theorem). Following von Neumann, we suppose that the vacuum state is a quantum ensemble. The vacuum state is degenerated with respect to quantum numbers of non-vacuum states with the distribution function that yields the Casimir effect in gravidynamics in analogy to the one in electrodynamics. The generation functional of the pertu...

Each of these problems consists of a system that results from the coupling of two highly nonlinear partial differential equations, one hyperbolic or parabolic and the other elliptic. These systems take their name from a formal analogy with the von Karman equations in the theory of elasticity in two dimensional space. We establish local (respectively global) results for strong (resp., weak) solutions of these problems and corresponding well-posedness results in the Hadamard sense. Results are found by obtaining regularity estimates on solutions which are limits of a suitable Galerkin approximation scheme. The book is intended as a pedagogical introduction to a number of meaningful application of classical methods in nonlinear Partial Differential Equations of Evolution. The material is self-contained and most proofs are given in full detail. The interested reader will gain a ...

    Full Text Available El presente artículo analiza el modo en el que Lars von Trier recrea para el cine el estereotipo de Medea. Mediante el análisis fílmico de la película y apoyándose en los estudios culturales, el texto se interroga acerca de la importancia y el poder potencial del cine a la hora recuperar el antiguo mito y demostrar su vigencia. El análisis amplía horizontes para la compresión de los mecanismos que articulan el entramado de significados de la película, donde Von Trier aporta una nueva visión del arquetipo de Medea uniéndola, a la tradición pictórica del Romanticismo. Una influencia que habita en las posteriores obras del director danés, donde el paisaje, la naturaleza, se erige en elemento catalizador de las pulsiones humanas, en su cómplice y testigo.This paper explores the way that Lars von Trier’s film recreates the stereotype of Medea. Using film analysis and based on cultural studies the article asks about the importance and potential power of cinema to recover the ancient myth and show their effects. The analysis expands horizons for the understanding of the mechanisms that link the network of meanings of the film, where the author offers a new vision of Medea's archetype attaching it to the pictorial tradition tied to the Romanticism. An influence that can be seen in the later works of Lars von Trier, where the landscape, the nature, stands as a catalyst of human drives, as his accomplice and witness.

    1. Die Deacetylierung von crabshell - Chitosan führte gleichzeitig zu einem drastischen Abfall der mittleren viscosimetrischen Molmasse ( Mv), insbesondere wenn die Temperatur und die Konzentration an NaOH erhöht werden. Diese Parameter beeinflussten jedoch nicht den Grad der Deacetylierung (DD). Wichtig ist jedoch die Quelle des Ausgangsmaterials: Chitin aus Pandalus borealis ist ein guter Rohstoff für die Herstellung von Chitosan mit niedrigem DD und gleichzeitig hoher mittlerer Mv, während Krill-Chitin (Euphausia superba) ein gutes Ausgangsmaterial zur Herstellung von Chitosan mit hohem DD und niedrigem Mv ist. Chitosan, das aus Insekten (Calliphora erythrocephala), unter milden Bedingungen (Temperatur: 100°C, NaOH-Konzentration: 40 %, Zeit: 1-2h ) hergestellt wurde, hatte die gleichen Eigenschaften hinsichtlich DD und Mv wie das aus Krill hergestellte Chitosan. Der Bedarf an Zeit, Energie und NaOH ist für die Herstellung von Insekten-Chitosan geringer als für crabshell-Chitosan vergleichbare Resultaten für DD und Mv. 2. Chitosan wurde durch den Schimmelpilz Aspergillus fumigatus zu Chitooligomeren fermentiert. Die Ausbeute beträgt 25%. Die Chitooligomere wurden mit Hilfe von HPLC und MALDI-TOF-Massenspektrmetrie identifiziert. Die Fermentationsmischung fördert die Immunität von Pflanzen gegen Bakterien und Virusinfektion. Die Zunahme der Immunität schwankt jedoch je nach System Pflanze-Pathogen. Die Fermentation von Chitosan durch Aspergillus fumigatus könnte eine schnelle und billige Methode zur Herstellung von Chitooligomeren mit guter Reinheit und Ausbeute sein. Eine partiell aufgereinigte Fermentationsmischung dieser Art könnte in der Landwirtschaft als Pathogeninhibitor genutzt werden. Durch kontrollierte Fermentation, die Chitooligomere in definierter Zusammensetzung (d.h. definierter Verteilung des Depolymerisationsgrades) liefert, könnte man zu Mischungen kommen, die für die jeweilige Anwendung eine optimale Bioaktivität besitzen. 3

Aufbauend auf Thomas Häckers dreidimensionalem heuristischen Modell zur Charakterisierung von Portfolios erarbeiten die AutorInnen ein Analyseraster, das Lehrenden, die (E-Portfolios in ihren Veranstaltungen nutzen wollen, als Instrument dienen kann, deren Einführungsprozess zu unterstützen und als Lernprozess zu gestalten. Das veränderte Mediennutzungsverhalten Jugendlicher und junger Erwachsener im Web 2.0 steht bei Michael J. Eble im Fokus. Die zunehmende Nutzung von Social Networks wie Facebook zur individuellen Selbstdarstellung kann nach Eble in Kombination von E-Portfolios und dem identitätsbasierenden Ansatz der Markenbildung für die Abbildung eigener Lern- und Leistungsentwicklung in Lehr- und Lernkontexten nutzbar gemacht werden. Unter drei zentralen Fragestellungen zur Auseinandersetzung mit der eigenen Person und Identität, zum Bezug zwischen persönlicher Markenbildung und formellen Lehr-Lern-Kontexten und zur Adoption und Akzeptanz von E-Portfolios untersucht Eble Chancen und Grenzen von E-Portfolios im Zeitalter des Social Networking. Dirk Jahn, Bernhard Trager und Karl Wilbers zeigen am Beispiel einer beruflichen Weiterbildung für Berufsbildungspersonal aus der Aus- und Weiterbildung im Einzelhandel die Möglichkeiten des Portfolioeinsatzes zur Qualifizierung dieser pädagogischen Professionals in restriktiven Settings. Als Grundlage für die Gestaltung von E-Portfolios dienen den Autoren in diesem Zusammenhang die Referenztheorien des Konzeptwandels, der Selbstreflexion und des kritischen Denkens. Darauf basierend werden die Phasen der E-Portfolioarbeit beispielhaft beschrieben, wobei vor allem die Einstiegsphase und der dissonanzgetriebene E-Portfolio-Prozess als bedeutend für das Gelingen der portfoliogestützten Qualifizierung der pädagogischen Professionals markiert werden.

  15. A Trajetória do Pensamento Econômico de Karl Marx

    Directory of Open Access Journals (Sweden)

    Inez Rocha Zacarias

    2017-02-01

    Full Text Available A construção do pensamento científico de Karl Marx está assentada nas grandes transformações societárias ocorridas no século XVIII, a partir da revolução industrial, das mudanças do modo de produção dominante e das erupções políticas revolucionárias que marcaram o Velho Continente, notadamente na Inglaterra e na França. A natureza do materialismo histórico-dialético só pode ser explicada pelas influências advindas da filosofia hegeliana, do socialismo utópico francês e da economia clássica inglesa. Estas escolas do pensamento, predominantes num período pós-Revolução Burguesa, foram objetos de estudo incansável de Marx, sendo dessa forma fundamentais para compreender a formação do pensamento desse autor. Esse artigo está centrado no seu pensamento econômico, para o qual a Escola Clássica foi fundamental. É reconhecido que o grande estímulo que provocou Marx a percorrer o caminho dos estudos econômicos foi a sua sensibilidade com os problemas gerados pela questão social, já demasiadamente manifestos nos seus primeiros escritos, enquanto jornalista da Gazeta Renana. Contudo, foram os clássicos da economia inglesa que, somados ao contexto econômico-social que se formava principalmente no país que serviu de berço para ascensão do capitalismo a Inglaterra que lhe forneceram os subsídios necessários para a construção da sua crítica da economia política, que culminou na sua principal obra, O Capital, publicada em 1867, considerada até os dias atuais umas das mais importantes obras econômicas de todos os tempos.

  16. Determination of kinetics of the karl Fischer reaction based on coulometry and true potentiometry.

    Science.gov (United States)

    Cedergren, A

    1996-03-01

    A new measurement technique based on a combination of coulometry and zero-current potentiometry is described for determination of the kinetics of rapidly reacting Karl Fischer (KF) reagents. This makes it possible to determine the order as well as the rate constant for large variations in the concentrations of iodine and water present during a titration. It was shown that for imidazole-based methanolic reagents exposed to a large variation in the concentration of water, the KF reaction is first order with respect to iodine, sulfur dioxide, and water only for reagents in which the concentration of nonprotonated imidazole is very low. The rate constant determined for such a reagent (1 M imidazole, 0.8 M sulfur dioxide, 0.1 M iodine) was equal to that reported earlier in the literature. Regions showing first-order kinetics were also found for low concentrations of water when imidazole concentrations up to 2 mol/L were used, provided that these reagents had a quotient [Im](free)/[ImH(+)] around 4. In the interval 2-8 mol/L of imidazole, the order of the reaction with respect to iodine was, in most cases, one-half, while it was changed to between one-half and one with respect to water. The rate of the KF reaction was found to increase by nearly 5 orders of magnitude for a reagent in which the concentration of nonprotonated imidazole was increased from 0 (rate constant equal to 2.6 × 10(3) L(2) mol(-)(2) s(-)(1)) to about 7 mol/L. For most of these reagents, a recovery rate close to 100% was attained. A high concentration of nonprotonated imidazole in combination with a high concentration of sulfur dioxide could, however, lead to a change in stoichiometry of the KF reaction when larger amounts of water were determined (250 μg of water added to 3.4 mL of reagent solution). A reaction scheme is proposed which might explain this change in stoichiometry observed for some reagent compositions. By use of the described most rapidly reacting reagents, it was shown to be

    Factors influencing the accuracy and precision for diaphragm-free Karl Fischer coulometric determinations of low mug-amounts of water have been studied using the Metrohm 756 (pulsed current) coulometer and eight different types of commercial coulometric reagents and some modifications of these. As in the case of diaphragm-free coulometric titration of large amounts of water, the positive errors, due to the formation of oxidizable reduction products (of sulfur dioxide) in the cathode reaction (besides hydrogen), were found to be minimized by the use of highest possible pulse current (in the range 100-400mA) in combination with the fastest possible titration rate. Most accurate (102-103%) and precise results (typical relative standard deviation 1.8%) were obtained for reagents containing very large concentrations of imidazole in combination with the presence of modifiers like hexanol, chloroform and propylene glycol (i.e. the HYDRA-POINT reagents). Similar results were obtained when this type of reagent was mixed 60/40 with xylene according to the ASTM recommendation for water determinations in petroleum products like crude and lubricating oils. Addition of decanol to this type of reagent mixture was found to reduce the influence from the oxidative reduction products significantly. A reduction of the error from 3.6% relative to 1.6% was achieved by addition of 9% (v/v) of decanol to a 60/40 reagent mixture of HYDRA-POINT Coulometric Gen (containing hexanol as modifier) and xylene. For larger concentrations of decanol the pulse current had to be lowered to 100mA and this might explain why no further improvement was observed. An additional attempt to minimize the interference by lowering the concentration of sulfur dioxide in the reagents gave no significant effect. However, by means of a home-built computer-controlled coulometric instrumentation based on continuous instead of pulsed current (including a large cathodic current density) it was possible to achieve

    A hundred years ago when Karl Jaspers was introducing psychological understanding to psychiatry the founder of the school of Heidelberg spoke of Friedrich Nietzsche as one of the "greatest" psychologists. Especially his theory of resentment with its core thesis unconscious prejudices were influencing our behaviour was able to illuminate the complex structure of human will. Taking into account this horizon of psychiatric history of ideas the presentation wants to persecute the following three questions: 1) Why the postulate which Nietzsche was giving on cultural prejudices of our thoughts, feelings and acts was so provocative so that many of the classical thinkers of psychological understanding were taking it up according to the needs of their disciplines sociology, psychology, psychiatry and philosophy? 2) What were the results of this inspiring theory which could be especially seen in the works of Karl Jaspers and Kurt Schneider? In other words: What were the aspects in which they agreed in their reception of Nietzsche and what were the points in which the two psychiatrists of the school of Heidelberg differed in the way they took the theory of resentment into account for their psychological understanding? 3) What could be the actual significance of the historical fact that Nietzsche and in his footsteps Max Weber were taking deep influence on psychiatric thinking around 1900?

  8. Comparison between amperometric and true potentiometric end-point detection in the determination of water by the Karl Fischer method.

    Cedergren, A

    1974-06-01

    A rapid and sensitive method using true potentiometric end-point detection has been developed and compared with the conventional amperometric method for Karl Fischer determination of water. The effect of the sulphur dioxide concentration on the shape of the titration curve is shown. By using kinetic data it was possible to calculate the course of titrations and make comparisons with those found experimentally. The results prove that the main reaction is the slow step, both in the amperometric and the potentiometric method. Results obtained in the standardization of the Karl Fischer reagent showed that the potentiometric method, including titration to a preselected potential, gave a standard deviation of 0.001(1) mg of water per ml, the amperometric method using extrapolation 0.002(4) mg of water per ml and the amperometric titration to a pre-selected diffusion current 0.004(7) mg of water per ml. Theories and results dealing with dilution effects are presented. The time of analysis was 1-1.5 min for the potentiometric and 4-5 min for the amperometric method using extrapolation.

  19. PREFACE: EmerQuM 11: Emergent Quantum Mechanics 2011 (Heinz von Foerster Congress)

    Grössing, Gerhard

    2012-05-01

    These proceedings comprise the plenary lectures and poster contributions of the 'Heinz von Foerster Conference 2011' on Emergent Quantum Mechanics (EmerQuM11), which was held at the University of Vienna, 11-13 November 2011. With the 5th International Heinz von Foerster Conference convened at the occasion of von Foerster's 100th birthday, the organizers opted for a twin conference to take place at the Large and Small Ceremonial Halls of the University's main building, respectively. The overall topic was chosen as 'Self-Organization and Emergence', a topic to which von Foerster was an early contributor. While the first conference ('Self-Organization and Emergence in Nature and Society') addressed a more general audience, the second one ('Emergent Quantum Mechanics') was intended as a specialist meeting with a contemporary topic that could both serve as an illustration of von Foerster's intellectual heritage and, more generally, point towards future directions in physics. We thus intended to bring together many of those physicists who are interested in or are working on attempts to understand quantum mechanics as emerging from a suitable classical (or, more generally, deeper level) physics. EmerQuM11 was organized by the Austrian Institute for Nonlinear Studies (AINS), with essential support from the Wiener Institute for Social Science Documentation and Methodology (WISDOM), the Department of Contemporary History at the University of Vienna, and the Heinz von Foerster-Gesellschaft. There were a number of individuals who contributed to the smooth course of our meeting and whom I would like to sincerely thank: Christian Bischof, Thomas Elze, Marianne Ertl, Gertrud Hafner, Werner Korn, Angelika Krawanja, Florian Krug and his team, Sonja Lang, Albert Müller, Ilse Müller, Irene Müller, Karl Müller, Armin Reautschnig, Marion Schirrmacher, Anton Staudinger, Roman Zlabinger, and, last but not least, my AINS colleagues Siegfried Fussy, Herbert Schwabl and Johannes Mesa

    This article reviews the significance of the contributions of Ernst von Glasersfeld to research in science education, especially through his theoretical contributions on radical constructivism. As a field shaper, Glasersfeld's subversive ideas catalyzed debate in the science education community and fuelled transformation of many facets including research methods, ways of thinking about teaching and learning, curriculum, and science teacher education. Perturbations emanating from the debates on constructivism forged new pathways that led to the development and use of many of the sociocultural frameworks employed by authors in Cultural Studies of Science Education.

    2008-12-01

    Full Text Available L’intérêt pour le travail de Karl Polanyi s’est renforcé avec l’avènement de la globalisation néo-libérale, et il peut encore s’accentuer étant donné la catastrophe engendrée par celle-ci. En 1944, l’ouvrage « La Grande Transformation » expliquait les difficultés rencontrées par le capitalisme entre les deux guerres. Elles résultaient en particulier de la tendance à instaurer un marché auto-régulateur depuis le 19ème siècle. La société a réagi à cette tendance pour s’y opposer. Polanyi attendait donc une réarticulation de l’économie et de la société à travers la planification sociale, mais il n’avait pas anticipé la relance de l’économie de marché sous le leadership américain. Il s’est ensuite consacré à l’économie pré-industrielle, à la fois formelle et substantive. Plus tard, son concept d’encastrement a été central dans l’émergence d’une nouvelle sociologie économique. Aujourd’hui, son analyse du capitalisme financier avant la première guerre mondiale et le désastre de l’entre deux guerres est d’une pertinence particulière.The interest for the work of Karl Polanyi has increased with the avent of neoliberal globalization and it may still increase given the catastrophies which follow. In 1944, in his book The Great Transformation, Karl Polanyi explained the difficulties encountered by capitalism between the two wars. They resulted in part from the tendency to try to establish an autoregulating market since the 19 th century. Society reacted to this and opposed this trend. Polanyi expected a rearticulation of economy and society through social planification, but he had not anticipated the development of market economy under leadership of the USA. He then went on to study preindustrial economies, from a formal and substantive point of view. Later on, his concept of embeddedness was central in the emergence of a new Economic Sociology. Today, his analysis of financial

    2006-01-01

    Dies ist die Geschichte von Einsteins unvollendeter Revolution, einer tiefgreifenden Veränderung unserer Begriffe von Raum, Zeit, Materie und Strahlung. Diese Revolution begann in Einsteins Wunderjahr 1905, wurde durch seine allgemeine Relativitätstheorie aus dem Jahre 1915 fortgesetzt und wirkt in den heutigen Versuchen der Wissenschaft, die Entstehung und das Schicksal des Universums zu verstehen, weiter. Vor dem Hintergrund einer historischen Theorie des wissenschaftlichen Fortschritts wird Einsteins bis heute nicht abgeschlossene Revolution als das Ergebnis einer langfristigen Entwicklung des Wissens verständlich. Anhand der spannenden Geschichte von Einsteins Entdeckungen wird nachvollziehbar, warum große Denker wie Einstein weiter gesehen haben als ihre Vorgänger. Sie standen nicht nur auf den Schultern von Riesen, also den wissenschaftlichen Leistungen einzelner großer Vorgänger wie Newton, sondern auch auf den Schultern von "Zwergen", dem wissenschaftlichen Wissen, dem technischen Wissen, und d...

    Hydrological tracer techniques are a means of making statements on the direction and speed of underground water. One of the simpler tasks is to find out whether there is hydrological communication between two given points. This requires a determination of the direction of flow, which places less exacting demands on the properties of the tracer than does the task of determining the flow velocity of underground water. Tracer methods can serve to infer from flow velocity the distance (flow) velocity, which is defined as the ratio between the distance between two points located in flow direction and the actual time it takes water to flow from one to the other. [Deutsch] Mit Hilfe der hydrologischen Markierungstechniken koennen Aussagen ueber die Richtung und die Geschwindigkeit von Bewegungen des unterirdischen Wassers gemacht werden. Der einfachere Fall liegt vor, wenn festgestellt werden soll, ob zwischen zwei Punkten eine hydrologische Verbindung besteht. Bei dieser Fliessrichtungsbestimmung sind die Forderungen an die Eigenschaften der einzusetzenden Tracer geringer als bei der Bestimmung der Geschwindigkeit des unterirdischen Wassers. Von den Geschwindigkeiten des unterirdischen Wassers ist die Abstands-(Fliess)geschwindigkeit, die definiert ist durch das Verhaeltnis aus dem Abstand und der wahren Fliesszeit zwischen zwei in Bewegungsrichtung gelegenen Punkten, durch Tracermethoden zu bestimmen.

    Guy von Dardel, a well-known figure at CERN and in the international particle physics community, passed away on 28 August. Guy von Dardel came to CERN when it was founded in 1954 and was a full-time staff member until 1964, performing several experiments and working on technical developments. These included the first measurement of the neutral pion’s life-time. Called to Lund University in 1964, he became professor there in 1965 and director of the 1.2 GeV electron accelerator. In the late 1960s, he performed an experiment at CERN’s PS that measured the decays of the Λ. Then, in the early 1970s, he involved the Lund group in a series of experiments at the Intersecting Storage Rings (ISR), where he measured the production of various types of particles. In particular, he participated in a series of experiments that observed the production of a high abundance of particles with large transverse momenta. This required an explanation...

  3. Approximate von Neumann entropy for directed graphs.

    2014-05-01

    In this paper, we develop an entropy measure for assessing the structural complexity of directed graphs. Although there are many existing alternative measures for quantifying the structural properties of undirected graphs, there are relatively few corresponding measures for directed graphs. To fill this gap in the literature, we explore an alternative technique that is applicable to directed graphs. We commence by using Chung's generalization of the Laplacian of a directed graph to extend the computation of von Neumann entropy from undirected to directed graphs. We provide a simplified form of the entropy which can be expressed in terms of simple node in-degree and out-degree statistics. Moreover, we find approximate forms of the von Neumann entropy that apply to both weakly and strongly directed graphs, and that can be used to characterize network structure. We illustrate the usefulness of these simplified entropy forms defined in this paper on both artificial and real-world data sets, including structures from protein databases and high energy physics theory citation networks.

    Full Text Available Supraventrikuläre Tachykardien (SVT spielen in der klinischen Praxis aufgrund ihrer Häufigkeit und Symptomatik eine große Rolle. Obwohl diese Arrhythmien im Allgemeinen nicht lebensbedrohlich sind, führen sie aufgrund ihres unvorhersehbaren Auftretens zu einer beträchtlichen Unsicherheit und Einschränkung der Lebensqualität. Die elektrophysiologische Untersuchung inklusive Katheterablation hat sich in den vergangenen 20 Jahren als kurative und sichere Erstlinientherapie für Patienten mit hochsymptomatischen bzw. wiederholten Anfällen etabliert. Heutzutage liegen die Erfolgsraten für die Radiofrequenzablation der regulären SVT über 95 % bei einer sehr niedrigen Rezidivrate von weniger als 5 %. Eine antiarrhythmische Therapie für das Langzeitmanagement ist aufgrund der geringen Effektivität und Gefahr von ernsthaften Nebenwirkungen weitgehend obsolet und nur in Ausnahmefällen erforderlich.

  8. Rethinking the diagnosis of von Willebrand disease.

    Favaloro, Emmanuel J

    2011-01-01

    von Willebrand disease (VWD) is the most common inherited bleeding disorder and arises from deficiencies and/or defects in the plasma protein von Willebrand factor (VWF). VWD is classified into 6 different types, with type 1 identified as a (partial) quantitative deficiency of VWF, type 3 defined by a (virtual) total deficiency of VWF, and type 2 identifying four separate types (2A, 2B, 2M, 2N) characterised by qualitative defects. The classification is based on phenotypic assays including FVIII, VWF:Ag and VWF activity, typically by ristocetin cofactor (VWF:RCo), but also increasingly by collagen binding (VWF:CB). Phenotypic testing may be supplemented by multimer analysis, RIPA, and VWF:FVIII binding. Although genetic analysis is not required to diagnose VWD or to define a classification type, it may be useful in discrete situations. The current review briefly covers this diagnostic process, with a focus on newer approaches, including extended test panels and the use of data from desmopressin challenges as a diagnostic tool.

  11. Alexander von Humboldt in Daniel Kehlmanns Welt

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available Zusammenfassung Wie stark sich im Verlauf des zurückliegenden Vierteljahrhunderts der Bekanntheitsgrad Alexander von Humboldts in der deutschsprachigen Öffentlichkeit verändert hat, zeigen nicht nur Fernsehumfragen zu den berühmtesten Deutschen, in denen Alexander von Humboldt mittlerweile figuriert, oder Fernsehserien, die über aktuelle Expeditionen berichten und auf Humboldts Namen zurückgreifen. Am deutlichsten vielleicht belegt dies der enorme Erfolg von Daniel Kehlmanns Roman Die Vermessung der Welt, der ohne die zuvor skizzierte Entwicklung nicht denkbar gewesen wäre. Es ist vor diesem Hintergrund nicht nur reizvoll, sondern aufschlußreich, sich mit dem großen Erfolg dieses kleinen Romans zu beschäftigen. Worum geht es in Die Vermessung der Welt? Und wie läßt sich das „Phänomen Kehlmann“ aus etwas größerer Distanz erklären? Abstract In the last 25 years, Alexander von Humboldt‘s popularity has radically changed in the german-speaking public opinion. Proof of this are not only television surveys about the most famous germans - in which Alexander von Humboldt now regularly figures - or television series about contemporary expeditions, which constantly refer to Humboldt‘s name; perhaps what most clearly verifies this change is the great success of Daniel Kehlmann‘s novel Die Vermessung der Welt. Without the recent developments outlined above, this novel‘s degree of impact would have been unimaginable. To study the great success of this text against this backdrop is not only attractive, but also revealing. What is Die Vermessung der Welt really about? And how can we explain the „Kehlmann phenomenon“ from a greater distance? Resumen La popularidad de Alejandro de Humboldt ha cambiado profundamente dentro del último cuarto de siglo en la opinión pública de habla alemana. Prueba de esto son no sólo las encuestas televisivas sobre los alemanes más famosos, dentro de las cuales figura en estos momentos Alejandro

    Full Text Available Zusammenfassung Im Juli des Jahres 1841 kommt es zu einem Treffen zwischen zwei Männern, das zunächst belanglos erscheint, sich aber Jahre später als wichtige historische Begebenheit herausstellen wird. In seinem Pariser Büro empfängt der 71jährige Naturforscher Alexander von Humboldt den jungen Preußen Ludwig Leichhardt. Der angehende Naturwissenschaftler erhofft sich Zuspruch und Empfehlung des berühmten Alexander von Humboldts. Die Unterredung ist kurz und verläuft für Leichhardt ergebnislos. Es wird das einzige Treffen der beiden Naturwissenschaftler bleiben. Aus heutiger Sicht unverständlich, da Ludwig Leichhardt und Alexander von Humboldt mehr verband, als ihre Leidenschaft für die Naturwissenschaften. Viel zu wenig ist sich bis jetzt den biographischen Analogien und den vergleichbaren geographischen Leistungen der beiden Preußen gewidmet worden. Abstract During July 1841 a meeting between two men takes place, which seems to have been extraneous, but turns out to be a significant historical incident. 71 year old natural scientist Alexander von Humboldt welcomes young Ludwig Leichhardt from Prussia in his office in Paris. The prospective young scientist expects help and references from famous Alexander von Humboldt. The conversation is short and ends from Leichhardt’s point of view without results. Unfortunately this is going to be the only meeting between the two scientists even though the two Prussians have more in common than their passion for the natural sciences. Way too seldomly have biographical analogy and geographical productivity of the two men been compared.

  13. [The Concept of Typology in Psychiatry in the Context of Historical Contributions of Max Weber and Karl Jaspers].

    Science.gov (United States)

    Jäger, M; Becker, T; Wigand, M E

    2016-08-01

    Against the background of Max Weber's and Karl Jaspers' outstanding historical contributions to the conceptual development of different typologies, the importance of a psychiatric typology is examined. The term "ideal type" was introduced into social science by Weber as an analytical construct to describe and classify cultural phenomena. This concept was adopted for the psychiatric context by Jaspers who proposed to establish a typological system in the field of psychotic disturbances without an organic correlate. He emphasized the importance of the course of psychopathological symptoms for such a typological system. The concept of typology can be regarded as a promising heuristic approach in psychiatry, providing a classification system for complex psychopathological symptoms. Even though several historic typologies exist in psychopathology, their usefulness in the fields of therapy and prognosis needs to be critically assessed. Also, new typologies will have to be developed, taking into account neurobiological knowledge now available.

    Full Text Available El presente artículo aborda el problema de la identidad y la otredad en la filosofía de Karl-Otto Apel, teniendo en cuenta que la estructura dialógica de la racionalidad permite pensar más allá de la filosofía tradicional de la conciencia. Según este objetivo, se emplean las categorías de ipseidad y mismidad, propuestas por Paul Ricoeur, a modo de instrumento metodológico, para realizar una lectura de la obra de Apel respecto al problema planteado. Así, el posicionamiento de Apel con relación a la dialogicidad y a la intersubjetividad pone de manifiesto la importancia de la argumentación colectiva en la configuración de una identidad a modo de ipseidad.

  19. Differentiation of rye and wheat flour as well as mixtures by using the kinetics of Karl Fischer water titration.

    2016-03-15

    The aim of this study was to find a simple way to differentiate between rye and wheat flour and their mixtures by using the kinetic parameters of Karl Fischer water titration (KFT). Consequently, the water content and type of molecules in rye and wheat mixtures used in Romanian bread making have been investigated by means of volumetric KFT. Further, the kinetics of KFT have been determined and novel kinetic parameters corresponding to "surface" and "strongly-retained" water molecules have been identified to discriminate between rye and wheat flour and their mixtures. The "surface" and "strongly-retained" water reaction rates well correlate with the rye content in the flour mixtures, especially at higher temperature analysis (r>0.95). These parameters can be used as indicators for quality evaluation of such type of mixtures, as well as to identify adulteration by improper use of the rye-wheat flour ratios in bread making.

  3. Update: SPECT in der Diagnostik von Parkinson-Syndromen

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Die Diagnose des Morbus Parkinson fußt primär auf Anamnese und klinischer Untersuchung. Die Abgrenzung von milden Bewegungsstörungen bei ansonsten gesunden älteren Personen, von medikamenteninduzierten und vaskulären Parkinson-Syndromen sowie von Tremor-Syndromen kann jedoch schwierig sein. Die Differenzierung zwischen M. Parkinson und atypischen Parkinson-Erkrankungen wie der Multisystematrophie (MSA und der progressiven supranukleären Paralyse (PSP ist im Frühstadium häufig unmöglich und kann auch in fortgeschrittenen Stadien Probleme bereiten. Die SPECT-Untersuchung mit Dopamin-Transporter- (DAT- Liganden wie 123I-FP-CIT erlaubt mit wenigen Ausnahmen bereits im Frühstadium eine Dokumentation der dopaminergen Degeneration beim M. Parkinson und atypischen Parkinson- Erkrankungen und damit meist eine Abgrenzung von nichtdegenerativen Parkinson- und Tremor-Syndromen. Sie kann die einzelnen degenerativen Parkinson-Syndrome jedoch nicht voneinander unterscheiden. Die Untersuchung postsynaptischer Dopamin- D2-Rezeptoren mit der 123I-IBZM-SPECT kann zur Differenzierung von M. Parkinson und MSA bzw. PSP beitragen. Neueren Untersuchungen zufolge dürften die Untersuchung des zerebralen Glukosemetabolismus mittels 18F-FDG-PET sowie moderne MRT-basierte Methoden in dieser Fragestellung jedoch eine höhere Sensitivität und Spezifität haben. Während Medikamente die diagnostische Aussagekraft von DAT-SPECT-Untersuchungen selten beeinflussen, kann das Ergebnis der IBZM-SPECT sowohl durch dopaminerge Substanzen als auch durch Dopaminantagonisten stark verfälscht werden. Die richtige Interpretation von SPECT-Daten setzt darüber hinaus die Kenntnis der individuellen strukturellen bildgebenden Befunde voraus. Eine MRT- oder CCTUntersuchung sollte zum Ausschluss von läsionellen Parkinson-Syndromen und zur Dokumentation von Kopathologien immer Bestandteil der Parkinson-Abklärung sein.

  5. Valence bond and von Neumann entanglement entropy in Heisenberg ladders.

    Science.gov (United States)

    Kallin, Ann B; González, Iván; Hastings, Matthew B; Melko, Roger G

    2009-09-11

    We present a direct comparison of the recently proposed valence bond entanglement entropy and the von Neumann entanglement entropy on spin-1/2 Heisenberg systems using quantum Monte Carlo and density-matrix renormalization group simulations. For one-dimensional chains we show that the valence bond entropy can be either less or greater than the von Neumann entropy; hence, it cannot provide a bound on the latter. On ladder geometries, simulations with up to seven legs are sufficient to indicate that the von Neumann entropy in two dimensions obeys an area law, even though the valence bond entanglement entropy has a multiplicative logarithmic correction.

  6. A von Bertalanffy growth model with a seasonally varying coefficient

    Cloern, James E.; Nichols, Frederic H.

    1978-01-01

    The von Bertalanffy model of body growth is inappropriate for organisms whose growth is restricted to a seasonal period because it assumes that growth rate is invariant with time. Incorporation of a time-varying coefficient significantly improves the capability of the von Bertalanffy equation to describe changing body size of both the bivalve mollusc Macoma balthicain San Francisco Bay and the flathead sole, Hippoglossoides elassodon, in Washington state. This simple modification of the von Bertalanffy model should offer improved predictions of body growth for a variety of other aquatic animals.

This leads to the well-known structural-physics and hygienic consequences. As an added effect, the distinctly enhanced thermal insulation results in changes in dynamic heat loss. The paper focuses on the issues of how to safeguard the inflow of fresh air, and the heating capacity of radiators.

  12. Hermann von Helmholtz and the empiricist vision.

    Science.gov (United States)

    Turner, R S

    1977-01-01

    The philosophical convictions of Hermann von Helmholtz and the empiricist psychology he developed have been extensively discussed in historical literature. This literature has not usually emphasized the tacti assumptions about human physiology that underlaid these convictions nor the way in which Helmholtz's epistemology served as a methodological directive in his research. Helmholtz assumed nerve transmission between sense organs and the mind to be a passive process. Distortion in stimulus patterns occurs physically in the sense organs, which can therefore be treated through mechanical analogies. Stimuli become converted to the perceptions of consciousness through mental processes that are essentially analogous to conscious, inductive inference and that are therefore susceptible, in principle, to introspective investigation. This view of mental function reflected Helmholtz's intellectual debt to German idealism, especially to the philosophical views of J.G. Fichte.

    Full Text Available Untherapierter Wachstumshormonmangel im Erwachsenenalter (AGHD ist mit viszeraler Adipositas, Dyslipidämie, Insulinresistenz und Fettleber verbunden. Interessanterweise finden sich viele der AGHD-Merkmale auch bei Patienten mit metabolischem Syndrom. Die nichtalkoholische Fettlebererkrankung (NAFLD gilt als hepatische Manifestation des metabolischen Syndroms. In einigen Studien wurden bei Patienten mit NAFLD verminderte Konzentrationen von zirkulierendem IGF-1, dessen Synthese zu einem großen Teil durch Wachstumshormon (GH reguliert wird, beschrieben. Mäuse, welche eine hepatische Wachstumshormondefizienz aufweisen, zeigen zahlreiche phänotypische Charakteristika des metabolischen Syndroms, unter anderen auch eine Fettlebererkrankung. Dies legt einen Zusammenhang zwischen dem Wachstumshormon und der Entstehung einer NAFLD nahe. Ziel unserer Studie ist es, in einem Zellkulturmodell die Effekte des Wachstumshormons auf den intrazellulären Glukosestoffwechsel näher zu untersuchen. Im Detail sollen Auswirkungen einer verminderten Wachstumshormonrezeptorexpression auf den Insulinsignaltransduktionsweg, den Glykogengehalt und auf Schlüsselenzyme der Glukoneogenese untersucht werden. Präliminäre Daten zeigen, dass eine verminderte Wachstumshormonrezeptorexpression mit intrazellulären Veränderungen des hepatischen Glukosestoffwechsels verbunden ist. Die verminderte Insulinsensitivität könnte auf Alterationen im Insulinsignaltransduktionsweg und Änderungen der Glukoneogenese zurückzuführen sein. Diese präliminären Daten weisen darauf hin, dass Wachstumshormon einen direkten Einfluss auf den Glukosestoffwechsel in der Leber hat. Zudem legen sie nahe, dass Veränderungen im Wachstumshormonstoffwechsel einen wichtigen pathophysiologischen Mechanismus in der Entstehung der Fettlebererkrankung bei Patienten mit metabolischem Syndrom darstellen könnten. Der folgende Artikel soll einen kurzen Überblick über die Effekte von Wachstumshormon

    Full Text Available Johann Friedrich Herbart (1776-1841 gilt als der Begründer der wissenschaftlichen Pädagogik. In diesem Beitrag wird zu zeigen versucht, dass Herbart die Unterstützung politischer Bildung als eine Aufgabe von Regierung, Unterricht und Zucht bestimmt und in seinem Werk wichtige „Bausteine“ für eine Theorie der politischen Bildung unter den Bedingungen von Erziehung vorlegt hat. Nach Herbart ist das politische Selbst- und Weltverhältnis auf Sachverhalte bezogen, die nicht nur die Lebensführung einzelner Menschen, sondern die Lebensführung einer Mehrzahl von Menschen betreffen. Nicht das Zusammenleben von Menschen generell ist jedoch Orientierungsgesichtspunkt des politischen Selbst- und Weltverhältnisses, sondern nur das problematisch gewordene Zusammenleben. Politik ergibt sich nach Herbart aus einem Konflikt hinsichtlich der Frage, wie das Zusammenleben von Menschen geregelt sein sollte. Während die Regierung lediglich mittelbar einen Beitrag zur politischen Bildung leistet, indem sie die Voraussetzungen für Unterricht und Zucht bereitstellt, fungieren die beiden zuletzt genannten Formen von Erziehung als die eigentlichen Medien, in denen die politische Bildung im Sinne Herbarts ihren Ort hat.

Procuro sacar a la luz algunos argumentos que destacan su naturaleza específica. Presto atención también, aunque en menor medida, a la organización sistemática de este emprendimiento y destaco algunas de sus limitaciones. En un segundo momento, considero el proceso de la formación del texto que ha durado más de un decenio. Finalmente, el artículo subraya, comparando el CFF de 1976 con un ensayo programático que se remonta a 1939, hasta qué punto el CFF puede ser considerado, con palabras de K. Neufeld, suma de una teología- suma de una vidaMore than 25 years have gone since the publication of The Christian Foundations of Faith by Karl Rahner. As stated by Rahner himself, the text is not a synthesis of his theology, yet it may be well considered as the most important work of his thought. Even though it was originally thought of as an introductory course, according to Rahner, his proposal constitutes "the task of any theological study". We may assert that that this work is among the most important theological works of the XX century. This article first analyses the objective of this book, highlighting the arguments of its specific nature, while paying attention to its systematic structure and some of its limitations.

    The RCP method was designed as a residue-optimised alternative to the thermally optimised grate firing of residual wastes. Its technical realisation and development to market maturity took no more than 5 years. In the first process stage the waste is converted to high-carbon pyrolysis charcoal and high-rank gas in the absence of oxygen. In the second stage these substances are oxidised by addition of oxygen. The resulting temperature causes the non-combustible constituents of the slag to melt. In a third, optional, stage this molten slag can be liberated of (heavy) metals to such an extent that it can subsequently be used directly as additive for grinding. Further exhaust gas treatment is facilitated by the use of a circulatory fluidised-bed secondary combustion chamber. Despite the reduced flue gas volume and resultant higher pollutant concentrations in the crude gas, overall emissions are lower than in conventional plants. [Deutsch] Das reststoffoptimierte RCP Verfahren ist als Alternative zur thermisch optimierten Rostverbrennung von Restabfaellen konzipiert. In nur fuenf Jahren wurde das Verfahren technisch umgesetzt und zur Marktreife entwickelt. In einer ersten Stufe des Verfahrens wird der Abfall unter Luftabschluss in einen kohlenstoffreichen Pyrolysekoks und eine heizwertreiches Gas umgesetzt. Im zweiten Schritt werden diese Stoffe unter Zugabe von Sauerstoff oxidiert. Dabei treten Temperaturen auf, bei denen die nichtbrennbaren Bestandteile der Schlacke schmelzen. Optional wird diese Schmelzschlacke in einem dritten Schritt derart von (Schwer-) Metallen befreit, dass sie anschliessend direkt als Zement-Zumahlstoff eingesetzt werden kann. Die Nutzung der zirkulierenden Wirbelschicht - Nachbrennkammer zur Abgasbehandlung vereinfacht die weitergehende Abgasbehandlung. Trotz verringertem Rauchgasvolumen und damit hoeheren Schadstoffkonzentrationen im Rohgas werden die Gesamtemissionen gegenueber konventionellen Anlagen verringert. (orig./SR)

The results could be pointed as follows: (i it characterises the intrinsic features of the metaphysical thought of Jaspers as the basis for the theory of 'ultimate' situations; (ii it shows how the theory determined his existential anthropology; and, finally, (iii it explains how the theory culminates in the notion of the death as the most specific formulation. In that respect, the paper determines how the notion of the death expresses the intrinsic features of the Jaspers' existential kind of philosophizing by reflecting its spirit in the most profound manner. In Jaspers' philosophy the death stands as the key exemplification of 'ultimate' situations (in terms of philosophical reflection and as the point of the reference in order to obtain the meaning of concrete life (in terms of significance for the individual existence.

    2012-12-01

    Full Text Available The issue of legitimizing political power has specific dimensions determined by the historical context. In the period following the First World War, democratic regimes dramatically collapsed due to ample protest movements against the political establishment from different countries, but also as a result of a serious political legitimation crisis, thus making way for the rise of totalitarian regimes of Fascism and Nazism. That time debates on the problem of legitimization political power are symptomatic. Due to the general perception regarding corruption in politics and to the political incapacity to deal with social problems, we can witness a decrease of trust in contemporary democratic regimes.In order to exemplify, in a brief expositive manner, my paper will present the topic of political legitimation approached by Max Weber and Karl Jaspers, in a selection of relevant texts issued by both authors during 1919-1931. The aim of this paper is to highlight the actuality, the validity of Weber’s and Jasper’s statements and also their capacity to give pertinent responses to questions such as: What role do the common values play in the legitimating of power in a democratic society? Are there any kinds of limits regarding the electoral legitimation? How can we make the difference between a legitimate appeal and an illegitimate one, between civism and terrorism?

    The past decades have seen a tremendous development in nuclear, middle, and high energy physics. This advance was in a great part promoted by the availability of newer and more powerful instruments. Over time, these instruments grew in size as well as in sophistication and precision. Nearly all these devices had one fundamental thing in common - magnetic fields produced with currents and iron. The precision demanded by the new experiments and machines did bring the magnet technology to new frontiers requiring the utmost in the accuracy of magnetic fields. The complex properties of the iron challenged innumerable physicists in the attempt to force the magnetic fields into the desired shape. Experience and analytical insight were the pillars for coping with those problems and only few mastered the skills and were in addition able to communicate their intricate knowledge. It was a fortuitous situation that the authors got to know Klaus Halbach who belonged to those few and who shared his knowledge contributing thus largely to the successful completion of two large instruments that were built at the Forschungszentrum Juelich, KFA, for nuclear and middle energy physics. In one case the efforts went to the large spectrometer named BIG KARL whose design phase started in the early 70`s. In the second case the work started in the early 80`s with the task to build a high precision 2.5 GeV proton accelerator for cooled stored and extracted beams known as COSY-Juelich.

    We present the first detections of thermal radio emission from the atmospheres of solar-type stars {\\tau} Cet, {\\eta} Cas A, and 40 Eri A. These stars all resemble the Sun in age and level of magnetic activity, as indicated by X-ray luminosity and chromospheric emission in calcium-II H and K lines. We observed these stars with the Karl G. Jansky Very Large Array with sensitivities of a few {\\mu}Jy at combinations of 10.0, 15.0, and 34.5 GHz. {\\tau} Cet, {\\eta} Cas A, and 40 Eri A are all detected at 34.5 GHz with signal-to-noise ratios of 6.5, 5.2, and 4.5, respectively. 15.0-GHz upper limits imply a rising spectral index greater than 1.0 for {\\tau} Cet and 1.6 for {\\eta} Cas A, at the 95% confidence level. The measured 34.5-GHz flux densities correspond to stellar disk-averaged brightness temperatures of roughly 10,000 K, similar to the solar brightness temperature at the same frequency.

    2012-03-01

    Full Text Available Karl Löwith (1897–1973 and Erich Auerbach (1892–1957 were assimilated German Jewish scholars who came to America during and after World War II. In the early 1940s both émigrés wrotetheir masterpieces From Hegel to Nietzsche and Mimesis in Japan and Turkey. In these books, the philosopher as well as the philologist, provide a certain philosophy of history forced by the historical crisis of Europe. The differences in their viewpoints can clearly be seen in their decisive judgments on Goethe and the French Revolution. The comparison first looks at the question what impact the reality of being expelled from the German University of Marburg had on the development of their thoughts. The expanding war and the persecution of the European Jews is taken into account as well. The second focus is directed on the experience both made at the American East Coast and how this might have influenced their later writings namely Meaning in History and Philology of World-Literature. And at last the question is raised which significance the Jewish-Christian background had for Löwith and Auerbach especially for their attitude towards the religious sphere.

  10. The Nazi ethnographic research of Georg Leibbrandt and Karl Stumpp in Ukraine, and its North American legacy.

    Schmaltz, E J; Sinner, S D

    2000-01-01

    Scholars have recently debated the topic of German academics who directly or indirectly served the Nazi machinery of death and who then went on to successful professional careers after the war. This article examines the activities of two prominent émigré scholars, Drs. Georg Leibbrandt (1899-1982) and Karl Stumpp (1896-1982). These Ukrainian Germans emigrated to Germany after World War 1. In America, most members of the Russian-German ethnic community never knew that Leibbrandt had represented Alfred Rosenberg's Ministry for the Occupied Eastern Territories, or that under his supervision Stumpp led a Sonderkommando in Ukraine. This unit classified hundreds of villages, indirectly documenting the annihilation of Jews and others. The authors conclude that one consequence of Leibbrandt's and Stumpp's "return to normalcy" after the war was the growing fascination with genealogical research that affected the Russian-German ethnic community in North America-research partly based on 1930s and 1940s Nazi racial record-keeping.

  11. Philosophy and phylogenetic inference: a comparison of likelihood and parsimony methods in the context of Karl Popper's writings on corroboration.

    de Queiroz, K; Poe, S

    2001-06-01

    Advocates of cladistic parsimony methods have invoked the philosophy of Karl Popper in an attempt to argue for the superiority of those methods over phylogenetic methods based on Ronald Fisher's statistical principle of likelihood. We argue that the concept of likelihood in general, and its application to problems of phylogenetic inference in particular, are highly compatible with Popper's philosophy. Examination of Popper's writings reveals that his concept of corroboration is, in fact, based on likelihood. Moreover, because probabilistic assumptions are necessary for calculating the probabilities that define Popper's corroboration, likelihood methods of phylogenetic inference--with their explicit probabilistic basis--are easily reconciled with his concept. In contrast, cladistic parsimony methods, at least as described by certain advocates of those methods, are less easily reconciled with Popper's concept of corroboration. If those methods are interpreted as lacking probabilistic assumptions, then they are incompatible with corroboration. Conversely, if parsimony methods are to be considered compatible with corroboration, then they must be interpreted as carrying implicit probabilistic assumptions. Thus, the non-probabilistic interpretation of cladistic parsimony favored by some advocates of those methods is contradicted by an attempt by the same authors to justify parsimony methods in terms of Popper's concept of corroboration. In addition to being compatible with Popperian corroboration, the likelihood approach to phylogenetic inference permits researchers to test the assumptions of their analytical methods (models) in a way that is consistent with Popper's ideas about the provisional nature of background knowledge.

    At the beginning of the 20th century, two known medical historians, Karl Sudhoff and Henry Ernst Sigerist, were among the first persons, who took up thorough investigations of medical manuscripts in Leipzig. Above all, it was Mr. Sudhoff, who developed his own procedure, in order to exploit the unknown stocks. Apart from the only means available to him, the so-called Leyser-papers, written by the Leipzig librarian Hermann Leyser, at least once Sudhoff made a complete check-up of all manuscripts over the period of 22 years. On 315 sheets he took down various more or less extensive notes regarding these Codices, which are kept today as manuscript collection (Ms 01269) in the library of the university of Leipzig. Many publications were written on the basis of these readings. Sigerist was only looking through a small number of Leipzig manuscripts, as could be seen from his remarks written onto the users' cards. However, he could rely on Sudhoff's notes and look for specific manuscripts that he was interested in and review them. This was a first and very important step for the investigation of Leipzig medical manuscripts.

    The efficiency of azeotropic distillation and oven evaporation techniques for trace determination of water in oils has recently been questioned by the National Institute of Standards and Technology (NIST), on the basis of measurements of the residual water found after the extraction step. The results were obtained by volumetric Karl Fischer (KF) titration in a medium containing a large excess of chloroform (> or = 65%), a proposed prerequisite to ensure complete release of water from the oil matrix. In this work, the extent of this residual water was studied by means of a direct zero-current potentiometric technique using a KF medium containing more than 80% chloroform, which is well above the concentration recommended by NIST. A procedure is described that makes it possible to correct the results for dilution errors as well as for chemical interference effects caused by the oil matrix. The corrected values were found to be in the range of 0.6-1.5 ppm, which should be compared with the 12-34 ppm (uncorrected values) reported by NIST for the same oils. From this, it is concluded that the volumetric KF method used by NIST gives results that are much too high.

    Geochronology is a fundamental measurement for planetary samples, providing the ability to establish an absolute chronology for geological events, including crystallization history, magmatic evolution, and alteration events, and providing global and solar system context for such events. The capability for in situ geochronology will open up the ability for geochronology to be accomplished as part of lander or rover complement, on multiple samples rather than just those returned. An in situ geochronology package can also complement sample return missions by identifying the most interesting rocks to cache or return to Earth. The K-Ar radiometric dating approach to in situ dating has been validated by the Curiosity rover on Mars as well as several laboratories on Earth. Several independent projects developing in situ rock dating for planetary samples, based on the K-Ar method, are giving promising results. Among them, the Potassium (K)-Argon Laser Experiment (KArLE) at MSFC is based on techniques already in use for in planetary exploration, specifically, Laser-induced Breakdown Spectroscopy (LIBS, used on the Curiosity Chemcam), mass spectroscopy (used on multiple planetary missions, including Curiosity, ExoMars, and Rosetta), and optical imaging (used on most missions).

  15. “God and the gods”: Faith and human-made idols in the theology of Karl Barth

    Full Text Available The First Commandment played an important role in the theology of Karl Barth. His personal obedience to this commandment contributed to his realization that one cannot be comfortable with the Liberal theology of the early twentieth century and accept the theological thinking that supported National Socialism. The First Commandment opened his eyes to see the idols, worldviews, ideologies and evil of his lifetime. The First Commandment is always in the background of his theology that concentrates on God’s revelation in Jesus Christ. Only two of his lectures specifically concentrated on the First Commandment, only one of which was published. Barth, understood the First Commandment as an axiom of theology. It is self-evident; a cornerstone and critical guideline for any theology that is built upon the biblical message. The article argues that if this aspect of Barth’s theology received attention in the Nederduitsch Hervormde Church, we would most probably have been saved from the conflicts concerning the ideology of apartheid and the “people’s church”.

    Richard von Volkmann (1830-1889), one of the most important surgeons of the 19(th) century, is regarded as one of the fathers of orthopaedic surgery. He was a contemporary of Langenbeck, Esmarch, Lister, Billroth, Kocher, and Trendelenburg. He was head of the Department of Surgery at the University of Halle, Germany (1867-1889). His popularity attracted doctors and patients from all over the world. He was the lead physician for the German military during two wars. From this experience, he compared the mortality of civilian and war injuries and investigated the general poor hygienic conditions in civilian hospitals. This led him to introduce the "antiseptic technique" to Germany that was developed by Lister. His powers of observation and creativity led him to findings and achievements that to this day bear his name: Volkmann's contracture and the Hueter-Volkmann law. Additionally, he was a gifted writer; he published not only scientific literature but also books of children's fairy tales and poems under the pen name of Richard Leander, assuring him a permanent place in the world of literature as well as orthopaedics.

  17. Geschichte der Natur bei Alexander von Humboldt

    Christian Helmreich

    2009-05-01

    Full Text Available Article in German, Abstracts in English, German and French.This article analyses the importance of an historical view of nature in the works of Alexander von Humboldt. In several of his first writings, Humboldt seems to outline the importance of what one may call history of nature. But even before his famous American travel, his position changed and he became reluctant to accept the seriousness of historical enquiry in the area of natural sciences: if we want to reconstruct the past state of nature, we cannot rely on empirical proofs; and history of nature is therefore necessarily based on uncertain hypotheses. Humboldt kept his sceptical attitude in the first decades of the 19th century, despite the positive results of the palaeontological researches of his scientific colleagues. However, he gradually convinced himself of the scientific interest of historical investigations in the natural sciences. The Cosmos paradoxally displays two apparently conflicting points of view: in his methodological remarks, Humboldt maintains that precise accounts of the past state of nature are out of reach of human knowledge, yet elsewhere in the same Cosmos he gives broad and rather vivid descriptions of the eventful history of nature.

  18. Modellbasierte Steuerung, Regelung und Diagnose von Brennstoffzellenantrieben

    Steigende Bevölkerungszahlen und damit zunehmender Energiebedarf stellen eine große Herausforderung für Menschheit und Umwelt dar. Mit steigendem Wohlstand ist auch ein stärkeres Bedürfnis nach Mobilität und damit ein höherer Energieverbrauch verbunden. Die derzeitigen enormen Steigerungen des Bruttoinlandsproduktes in China und Indien - zwei Ländern, die zusammen mehr als ein Drittel der Weltbevölkerung stellen - lassen auch zukünftig ungebrochene Steigerungen des Weltenergieverbrauches erwarten. Dies gilt für alle Bereiche, besonders aber für den Verkehrssektor. Letzterer stellt mit seinem signifikanten Anteil am Energieverbrauch sowie den damit einhergehenden Emissionen und seinem hohen Wachstumspotenzial ein besonderes Handlungsfeld dar. Insbesondere wegen der in diesem Sektor zu erwartenden ansteigenden CO2-Emissionen stehen Effizienzverbesserungen und die Entwicklung alternativer Antriebe im Vordergrund. Dabei spielt die Brennstoffzelle als Fahrzeugantrieb eine entscheidende Rolle, da sie einen hohen Systemwirkungsgrad mit fehlenden CO2- und Schadstoffemissionen verbindet. Wegen der hohen Komplexität sind dabei moderne Steuerungs-, Regelungs- und Diagnoseverfahren von besonderer Bedeutung, auf die in diesem Beitrag näher eingegangen wird. Neben einigen grundlegenden Konzepten wird an Hand zweier Beispiele das Potenzial modellgestützter Methoden aufgezeigt.
