Der Beitrag untersucht Dantes Verhältnis zur Mehrsprachigkeit, indem er die in "De vulgari eloquentia" enthaltenen Reflexionen bezüglich des Gegensatzes zwischen Volkssprache und gramatica und bezüglich der Suche nach einer italienischen Literatursprache (volgare illustre) nachzeichnet. Obwohl Dante in "De vulgari eloquentia" die Volkssprache höher bewertet als die "gramatica", weil sie im Gegensatz zu dieser natürlich sei und allen Menschen zur Verfügung stehe, dient ihm die "gramatica" aufgrund ihrer Stabilität als Vorbild für die erst noch zu schaffende, allgemein verbindliche und zeitüberdauernde Volkssprache als Literatursprache. Nach seiner Vorstellung ist das "volgare illustre" eine Quintessenz aller italienischen Varietäten und somit im Prinzip schon ein mehrsprachiges Instrument. Die Sprache der Divina Commedia ist geprägt durch eine konstitutive Mehrsprachigkeit, welche sich einerseits aus den verschiedenen Varietäten des Italienischen speist und andererseits aus den anderen Dante verfügbaren Sprachen, insbesondere dem Lateinischen, dem Okzitanischen und dem Altfranzösischen. Im Gegensatz zu der bis dahin in mehrsprachigen literarischen Texten üblichen Abgrenzung der Sprachen kommt es bei Dante zu einer Verschmelzung der Sprachen, welche vor allem auf der von ihm geschaffenen Form der Terzine beruht.
Cytokine-regulated GADD45G induces differentiation and lineage selection in hematopoietic stem cells
(2014)
The balance of self-renewal and differentiation in long-term repopulating hematopoietic stem cells (LT-HSC) must be strictly controlled to maintain blood homeostasis and to prevent leukemogenesis. Hematopoietic cytokines can induce differentiation in LT-HSCs; however, the molecular mechanism orchestrating this delicate balance requires further elucidation. We identified the tumor suppressor GADD45G as an instructor of LT-HSC differentiation under the control of differentiation-promoting cytokine receptor signaling. GADD45G immediately induces and accelerates differentiation in LT-HSCs and overrides the self-renewal program by specifically activating MAP3K4-mediated MAPK p38. Conversely, the absence of GADD45G enhances the self-renewal potential of LT-HSCs. Videomicroscopy-based tracking of single LT-HSCs revealed that, once GADD45G is expressed, the development of LT-HSCs into lineage-committed progeny occurred within 36 hr and uncovered a selective lineage choice with a severe reduction in megakaryocytic-erythroid cells. Here, we report an unrecognized role of GADD45G as a central molecular linker of extrinsic cytokine differentiation and lineage choice control in hematopoiesis.
Over the past decade, Scandinavian and German scholars have been active in the redefinition of the terms “Vitalism” and “Vitalist” as descriptive categories for analytical purposes in the fields of literary and cultural history. In this context,“Vitalism”has primarily been used to describe an enthusiastic worshipping of life, one that holds youth, health, strength and beauty as its primary attributes, which was prevalent in all aspects of cultural life around 1900. But even the post war founders of the Vitalist re-conceptualisation of this era, Wolfdietrich Rasch and Gunter Martens, warned of taking such a unilateral view ofwhat constituted a Vitalist concept of life. It could lead to a misunderstanding of Vitalist way of thinking, Rasch said, if the focus wasonly set upon the enthusiastic surplus, the worshipping of youth and health. To Vitalists, life is more than that. It is a totality that also encompasses notions of destruction, decay and death. “All life symbols in literature around 1900 are at the same time symbols of death” (Rasch, 1967:24).Through the analyses of three poems, this article aims to show concrete examples of how cyclic Vitalist thinking is embedded in poetry of the era. The analyses include a further sub-categorisation to capture the different types of Life Force dealt with in the texts. By way of an introduction, Vitalism is discussed within the context of the scientific and social developments of the 19th Century.
Customer equity reporting
(2014)
WHARTON SCHOOL OF BUSINESS AT UNIVERSITY OF PHILADELPHIA HAS JUSTLAUNCHED AN 8-WEEK ONLINE PROGRAM “STRATEGIC VALUE OF CUSTOMER RELATIONSHIPS – ONLINE” TAUGHT BY MARKETING PROFESSOR AND AUTHOR PETER FADER. HE INVITED PROFESSOR SKIERA, DIRECTOR OF THE E-FINANCE LAB, TO PHILADELPHIA TO LEARN ABOUT HIS THOUGHTS ON “CUSTOMER EQUITY REPORTING”. THIS ARTICLE SUMMARIZES SOME OF PROFESSOR FADER’S QUESTIONS AND PROFESSOR SKIERA’S REPLIES.
Customary Law Ascertained Volume 2 is the second of a three volume series in which traditional authorities in Namibia present the customary laws of their communities. It contains the laws of the Bakgalagari, the Batswana ba Namibia and the Damara communities. The recognised traditional authorities in Namibia are expected to ascertain the customary law applicable in their respective communities and to note the most important aspects of the laws in written form. The Ministry of Regional and Local Government, Housing and Rural Development, and the Council of Traditional Leaders therefore initiated the ascertainment of customary law. The ascertainment project is housed in the Human Rights and Documentation Centre of the University of Namibia. The former Dean of the Faculty of Law of the University of Namibia, Professor Manfred O. Hinz, has directed the project since its inception.
One of the motivations for establishing a European banking union was the desire to break the ties with between national regulators and domestic financial institutions in order to prevent regulatory capture. However, supervisory authority over the financial sector at the national level can also have valuable public benefits. The aim of this policy letter is to detail these public benefits in order to counter discussions that focus only on conflicts of interest. It is informed by an analysis of how financial institutions interacted with policy-makers in the design of national bank rescue schemes in response to the banking crisis of 2008. Using this information, it discusses the possible benefits of close cooperation between financial institutions and regulators and analyzes these in the wake of a European banking union.
This collection of essays on archaeology and heritage studies is authored by local and expatriate scholars who are either past or current practitioners in archaeological work in Ghana. They are from Ghana, UK, US and Canada. The subject matter covered includes the history and evolution of the discipline in Ghana; the method and theory or 'how to do it' in archaeology, field research reports, and syntheses on findings from past and recent investigations. The eclectic or multidisciplinary strategy has been the research vogue in Ghanaian archaeology recently, and this is reflected in the various chapters. The essays engage with current theoretical trends in global archaeology and also focus on the role and status of archaeology as a discipline in Ghanaian society today. Archaeology is a relatively 'novel' subject to many in Ghana. This Reader will, therefore, be a huge asset to local students and experts alike. Foreign scholars will also find it very useful.
Neoadjuvant systemic chemotherapy is a possible therapeutic approach for the treatment of locally advanced operable, primarily non-operable or inflammatory breast cancer. Neoadjuvant systemic chemotherapy is an option for breast cancer patients who would require adjuvant chemotherapy otherwise based on clinical and histological examination and imaging. The use of neoadjuvant systemic therapy in operable breast cancer is currently increasing because of its advantages that include higher rates of breast conserving surgery and the possibility of measuring early in-vivo response to systemic treatment. The timing of axillary sentinel lymph node diagnosis (i.e. before or after neoadjuvant chemotherapy) is critical in that it may influence the likelihood of axillary preservation. It is not yet clear if neoadjuvant therapy might improve outcomes in certain subgroups of breast cancer patients. Neoadjuvant treatment modalities require a close collaboration between oncology professionals, including surgeons, gynecologists, medical oncologists, radiation oncologists, radiologists and pathologists. The most important parameter for treatment success and improved overall survival is the achievement of a pathologic complete response (pCR), although the role of pCR in patients with luminal A like tumours might be less informative. Identification of patient subgroups with high pCR rates may allow less invasive surgical or radiological interventions. Patients not achieving a pCR may be candidates for postoperative clinical trials exploring novel systemic treatments.
Introduction: Curare is one of the best-examined neurotoxins of the world, which has empirically been used for centuries by American Indigenes. Research on curare has been performed much later, a global scientometric analysis on curare research or its derivates does not yet exist. This bibliometric analysis is part of the global NewQis-project and should illuminate both toxic and historic issues of research on curare.
Methods: The ISI Web of Science was searched for data covering 1900 to 2013 using a term which included as many original articles on curare as possible. 3,867 articles were found and analyzed for common bibliometric items such as the number of citations, language of the articles or the (modified) Hirsch-Index (h-index). Results are illustrated utilizing modern density equalizing map projections (DEMP) or beam diagrams.
Results: Most publications were located in North America and Europe. The USA has the highest number of publications as well as the highest h-index. The number of publications overall rose until the late 1990s and later decreased. Furthermore, sudden increases of research activity are ascribable to historic events, like the first use of curare as muscle relaxant during surgery.
Discussion: This scientometric analysis of curare research reflects several tendencies as previously seen in other bibliometric investigations, i.e. the scientific quality standard of North America and Europe. Research on curare decreased however, due to the declining attention towards this muscle relaxant. This work exemplifies also how scientometric methods can be used to illuminate historic circumstances immediately stimulating scientific research.
