Imperialismustheorien und Geschichte: Eine empirische Annäherung

For decades, if not centuries, the term imperialism has been used in manifold and ambivalent ways. Some historians, such as William Hancock, therefore shied away from using it in their texts, while others set up theories to explain as much as possible with regard to the European expansion into the non-European world – and in some cases even beyond. Taking the three cases of German colonial policy before 1890, the granting of “responsible government” to the so-called British dominions and the expansion of British power in South Asia from the mid-eighteenth century to 1914, this article seeks to show to what extent a knowledge of both older and more recent theories of imperialism can still be useful for empirical research in the humanities and the social sciences.

Gallipoli: Myths and Memories in a transnational perspective

The battle of Gallipoli as it is known in Europe and South Asia or the battle of Çannakkale as it is known in modern Turkey was a seminal battle for many nations, not because it was decisive for the course of the war, but because it played a central role in regard to memory of the First World War in many nations. Based on photographic evidence and research by colleagues from many countries this contribution will focus in a transnational perspective on the participation of British, Indian, Australian and New Zealand troops in the campaign and especially on myths and memories on the side of the Entente from 1916 onwards.

A Word. Palaver and Its Transferal Residues

The word 'palaver' is colloquially associated with useless verbiage and the nuisance of a tediously long, aimless and superfluous debate. At the same time, it insinuates an uncivilized culture of discourse beyond reason. Thus it appears to be of vaguely exotic origin but still firmly set in the European lexicon. Yet behind this contemporary meaning there lies a long history of linguistic and cultural transfers which is encased in a context of different usages of language and their intersections. By tracing the usage and semantics of 'palaver' in various encyclopaedias, glossaries and dictionaries of English, French, German, Portuguese and Spanish, the following article explores the rich history of this word. Moreover, it also regards the travelling semantics of the term 'palaver' as a process of cultural transfer that can be likened to the microcellular workings of a (retro)virus. Viral reproduction and evolution work through processes of transfer that enable the alteration of the host to adjust it to the replication and reproduction of the virus. In some cases, these processes also allow for the mutation or modification of the virus, making it suitable for transfer from one host to another. The virus is thus offered here as a vital model for cultural transfer: It not only encompasses the necessary adoption and adaption of contents or objects of cultural transfer in different contexts. It contributes to a conceptual understanding of the transferal residue that the transferred content is endowed with by its diversifying contexts. This model thereby surpasses an understanding of cultural transfer as literal translation or transmission: it conceptualizes cultural transfer as an agent of evolutionary processes, allowing for mutational effects of transfer as endowment.

Drought Adaptation in Millets

Millets are major food and feed sources in the developing world especially in the semi-arid tropical regions of Africa and Asia. The most widely cultivated millets are pearl millet [Pennisetum glaucum (L.) R. Br.], finger millet [Eleusine coracana (L.) Gaertn], foxtail millet [Setaria italica (L.) P. Beauvois], Japanese barnyard millet [Echinochloa esculneta (A. Braun) H. Scholz], Indian Barnyard millet [Echinochloa frumetacea Link], kodo millet [Paspalum scrobiculatum L.], little millet [Panicum sumatrense Roth.ex.Roem. & Schult.], proso millet [Panicum miliaceum L.], tef [Eragrostis tef (Zucc.) Trotter] and fonio or acha [Digitaria exilis (Kippist) Stapf and D. iburua Stapf]. Millets are resilient to extreme environmental conditions especially to inadequate moisture and are rich in nutrients. Millets are also considered to be a healthy food, mainly due to the lack of gluten (a substance that causes coeliac disease) in their grain. Despite these agronomic, nutritional and health-related benefits, millets produce very low yield compared to major cereals such as wheat and rice. This extremely low productivity is related to the challenging environment in which they are extensively cultivated and to the little research investment in these crops. Recently, several national and international initiatives have begun to support the improvement of diverse millet types.

TRPV1 Channels Contribute to Behavioral Hypersensitivity and Spontaneous Activity in Nociceptors After Spinal Cord Injury

A majority of persons who have sustained spinal cord injury (SCI) develop chronic pain. While most investigators have assumed that the critical mechanisms underlying neuropathic pain after SCI are restricted to the central nervous system (CNS), recent studies showed that contusive SCI results in a large increase in spontaneous activity in primary nociceptors, which is correlated significantly with mechanical allodynia and thermal hyperalgesia. Upregulation of ion channel transient receptor vanilloid 1 (TRPV1) has been observed in the dorsal horn of the spinal cord after SCI, and reduction of SCI-induced hyperalgesia by a TRPV1 antagonist has been claimed. However, the possibility that SCI enhances TRPV1 expression and function in nociceptors has not been tested. I produced contusive SCI at thoracic level T10 in adult, male rats and harvested lumbar (L4/L5) dorsal root ganglia (DRG) from sham-treated and SCI rats 3 days and 1 month after injury, as well as from age-matched naive control rats. Whole-cell patch clamp recordings were made from small (soma diameter <30 >μm) DRG neurons 18 hours after dissociation. Capsaicin-induced currents were significantly increased 1 month, but not 3 days, after SCI compared to neurons from control animals. In addition, Ca2+ transients imaged during capsaicin application were significantly greater 1 month after SCI. Western blot experiments indicated that expression of TRPV1 protein in DRG is also increased 1 month after SCI. A major role for TRPV1 channels in pain-related behavior was indicated by the ability of a specific TRPV1 antagonist, AMG9810, to reverse SCI-induced hypersensitivity of hindlimb withdrawal responses to heat and mechanical stimuli. Similar reversal of behavioral hypersensitivity was induced by intrathecal delivery of oligodeoxynucleotides antisense to TRPV1, which knocked down TRPV1 protein and reduced capsaicin-evoked currents. TRPV1 knockdown also decreased the incidence of spontaneous activity in dissociated nociceptors after SCI. Limited activation of TRPV1 was found to induce prolonged repetitive firing without accommodation or desensitization, and this effect was enhanced by SCI. These data suggest that SCI enhances TRPV1 expression and function in primary nociceptors, increasing the excitability and spontaneous activity of these neurons, thus contributing to chronic pain after SCI.

Marco Aurelio : filosofía y discurso íntimo

La obra de Marco Aurelio es la manifestación final de la ética estoica. El Emperador de Roma vive continuamente en medio de muchas guerras por la defensa de su territorio. Pueblos germánicos atacaban sus fronteras en el noreste cuando puso en orden para sus amigos muchos pensamientos o notas recopiladas durante años. Estas notas tienen forma de un cuaderno de notas o de un diario íntimo y contenido filosófico. Las teorías contemporáneas de la autobiografía han estudiado estas formas y definen sus rasgos con precisión, pero existen múltiples diferencias entre la personalidad de los hombres antiguos y modernos. Esto vuelve espinosa la interpretación de los pensamientos aurelianos si usamos solamente los conceptos actuales de la literatura íntima. Nuestro artículo muestra estas dificultades.
