My essay attends to a number of passages in Alexander von Humboldt’s "Personal Narrative" in which the Prussian explorer expresses anxiety about the apparent dangers posed by the overwhelmingly productive tropical landscapes he observes. In these passages, the excesses of an “exotic nature” threaten European identity and modes of civilization—and they trouble the accuracy of Humboldt’s own observational project. I also explore Humboldt’s related worry that South American vegetable (and visual) overload will exert a destabilizing effect on his aesthetic sensibility, disrupting his ability to represent the “New Continent” accurately in writing. Finally, I sketch the influence of Humboldt’s representations of tropical excess on nineteenth-century British cultural thought and literary practice. Studying the instabilities experienced by "Personal Narrative’s" expatriates and colonists promises to draw out important tensions latent in Humboldt’s treatment of tropical landscape and to illuminate broader epistemological and aesthetic shifts being worked out during the period.
An der Sprache des Rechts wird Kritik geübt, seit die Aufklärung die Verständlichkeit der Gesetze zu ihrem Anliegen gemacht hat. Mit den großen Kodifikationen des Rechts im ausgehenden 19. Jahrhundert hat die Kritik am angeblich schlechten, unverständlichen Juristendeutsch eine besondere demokratietheoretische Legitimation bekommen. Diese Sprachkritik sucht seit den siebziger Jahren vermehrt bei der Linguistik Rat, wie denn eine bessere Allgemeinverständlichkeit von Rechtstexten verwirklicht werden könnte. Der Band versammelt systematisch aufeinander bezogene Beiträge ausgewiesener Linguisten, Juristen und Schriftsteller zur Problematik des Verständnisses juristischer Sprache, zur Methodik empirischer Verständlichkeitsmessung und zu den Möglichkeiten transdisziplinärer Kooperation zwischen Rechts- und Sprachwissenschaftlern.

The article provides historical background for Alexander von Humboldt’s expedition into Russia in 1829. It includes information on Humboldt’s works and publications in Russia over the course of his lifetime, as well as an explanation of the Russian scientific community’s response to those works. Humboldt’s ideas on the existence of an active volcano in Central Asia attracted the attention of two prominent Russian geographers, P.Semenov and P.Kropotkin, whose views on the nature of volcanism were quite different. P.Semenov personally met Humboldt in Berlin. P. Kropotkin made one of the most important geological discoveries of the 19th Century: he found the fresh volcanic cones near Lake Baikal. Soon after Humboldt’s Russian expedition, and partly as a result of it, an important mineral was found in the Ilmen mountains - samarskite, which later gave its name to the chemical element Samarium, developed in 1879. At the beginning of the 20th Century, the Russian scientist V.Vernadskiy pointed out that samarskite was the first uranium-rich mineral found in Russia.
Stephen Jay Gould wrote recently that “when Church began to paint his great canvases, Alexander von Humboldt may well have been the world’s most famous and influential intellectual.” Humboldt’s influence in the case of the landscape artist Church is especially interesting. If we examine the precise relationship between the German explorer and his American admirer, we gain an insight into how Humboldt transformed Church’s life and signaled a new phase in the career of the artist. Church retraced Humboldt’s travels in Ecuador and in Mexico. If we compare the texts available to Church and the comparison of Church’s paintings and the texts and images of Humboldt’s works we can arrive at new perspectives on Humboldt’s extraordinary influence on American landscape painting in the nineteenth century.
Alexander von Humboldt’s descriptions of volcanic mountains in his travel journals (Reise auf dem Río Magdalena, durch die Anden und Mexico) show both his reliance on and impatience with literary conventions and travel narratives. Using Goethe’s Italienische Reise and Bürger’s Münchhausen as points of comparison for literary treatments of the volcano ascent, Humboldt’s process of writing is examined. Humboldt shows the failure of the existing discourse and begins to experiment with narratives which fragment and recombine personal and historical modes of writing with, in this case, images from new technical inventions which visualize landscape according to fundamental scientific principles. While the inclusion of scientific prose is relevant, Humboldt’s link to modernity is based on experimental narrative techniques which draw upon changing sets of discourse practices to describe complex realities.
Alexander von Humboldt’s maps, graphs and illustrations contain a great deal of detail, but in the available rare editions they are hardly visible to the naked eye. In many editions they have been reduced. In a digital library, they will become accessible in their entirety, and Internet technology will reproduce them in a form that overcomes the limitations of the original printing. The user will be able to enlarge the images and see details that might have been overlooked in the past. The Humboldt’s digital library will adhere to the standards for digital libraries established by the Open Archives Initiative (OAI) and the tools EPRINTS and DSPACE to provide the Web services and determine the most effective way to establish dynamic linking and knowledge based searching of information within the archive.
The study of structures is a common concern of all scientific disciplines. The motivation as well as the methods of analysis, however, differ considerably. In engineering, the generation of artifacts, of infrastructures or technological processes are of primary interest. Frequently, the analysis aims at an optimization of the structures and the structure generating processes. Quite different is the study and explanation of existing structures in biology and the social sciences. Here the question of optimality does not present itself in an unambiguous manner. Generally, it must be questioned whether biological and social structures, although developing in an evolutionary way, can be considered as leading towards an a-priori defineable goal of optimality. The complex scenario of qualitative and quantitative modeling, and the goal-oriented and statistical approaches to understanding the meliorisation efforts in the various fields of the sciences and humanities define the scope of this book. Its intention is to create trans-disciplinary insights into methods to fecundate the custom disciplinary approaches.
Responding to the Antique : a rediscovered Roman Circus Sarcophagus and its Renaissance Afterlife
(2005)
The recent discoveries of the Czech mission show clearly that Abusir formed with Saqqara a single geographical unit in ancient Egypt and that the modern separation of them is outdated. Abusir seems to have played the crucial role as the last area into which the necropolis expanded after exhausting the space occuppied by the Archaic Cemetery of North Saqqara. In fact, it is the last vestige before the move from the area (including Dahshur and Meidum) to Giza at the beginning of the Fourth Dynasty. The tombs of Hetepi and lty, discovered and explored during the past few years, are probably the final representatives of genuine Third Dynasty tomb evolution in the Saqqara-Abusir area which drew its last breath at the beginning of the Fourth Dynasty. These tombs undoubtedly belonged to the upper class in the society of the day, though certainly not to members of the royal family. Their characteristics clearly show exactly what preceded later tomb development at Meidum, Dahshur and Giza.
Die Erscheinungsform einer bestimmten Einzelsprache resultiert aus dem Nebeneinander und Zusammenwirken vertikaler und horizontaler Transmission von sprachlichen Merkmalen und umfasst demzufolge normalerweise neben Phänomenen, die über eine Kette früherer Sprechergenerationen ererbt wurden, auch solche, die aus anderen Sprachen entlehnt wurden. Deutliche Spuren einer komplexen Entstehungsgeschichte und der Interaktion verschiedener Sprachgemeinschaften lassen sich nicht erst im Altägyptischen oder gar erst in der Sprache des Neuen Reiches ausmachen, sondern bereits die frühesten schriftlichen Quellen aus der Zeit um 3000 v. Chr. erlauben – trotz ihrer Knappheit – überraschende Einblicke in die zeitgenössischen sprachlichen Verhältnisse. Bislang nur durch Sprachvergleich rekonstruierbare Entwicklungen sind nunmehr historisch nachweisbar, und das phonologische System einer dem Altägyptischen vorausgehenden und erheblich von ihm abweichenden Sprachstufe wird greifbar. Da das Voraltägyptische ein für eine afroasiatische Sprache eher untypisches Konsonanteninventar besitzt und sich zudem lexikalische Übereinstimmungen (nicht-genetischer Natur) mit indoeuropäischen Sprachen abzeichnen, erscheinen fundierte Hypothesen über die Herausbildung des Ägyptischen nicht länger unmöglich. Damit wäre das Ägyptische nicht nur die am längsten bezeugte Einzelsprache der Menschheitsgeschichte, sondern wohl auch die einzige, die von ihrer Entstehung bis zu ihrem Aussterben schriftlich dokumentiert ist.
Non-Oberbeck-Boussinesq (NOB) effects on the Nusselt number Nu and Reynolds number Re in strongly turbulent Rayleigh-Benard convection in liquids were investigated both experimentally and theoretically. In the experiment, the heat current, the temperature difference, and the temperature at the horizontal mid-plane were measured. Three cells of different heights L, all filled with water and all with aspect ratio T close to 1 were used. For each L, about 1.5 decades in Ra were covered, together spanning the ränge 108 < Ra < 1011. For the largest temperature difference between the bottom and top plates of ? = 40K the kinematic viscosity and the thermal expansion coefficient, due to their temperature dependence, varied by more than a factor of two. The Oberbeck-Boussinesq (OB) approximation of temperature independent material parameters thus was no longer valid. The ratio Ï? of the temperature drops across the bottom and top thermal boundary layers became as small as Ï? = 0.83, as compared to the ratio Ï? = 1 in the OB case. Nevertheless, the Nusselt number Nu was found to be only slightly smaller (at most 1.4%) than in the next larger cell with the same Rayleigh number, where the material parameters were still nearly height-independent. The Reynolds numbers in the OB and NOB case agreed with each other within the experimental resolution of about 2%, showing that NOB effects for this parameter were small as well. Thus Nu and Re are rather insensitive against even significant deviations from OB conditions. Theoretically, we first account for the robustness of Nu with respect to NOB corrections: the NOB effects in the top boundary layer cancel those which arise in the bottom boundary layer as long as they are linear in the temperature difference ?. The net effects on Nu are proportional to ?2 and thus increase only slowly and still remain minor despite drastic material parameter changes. We then extend the Prandtl-Blasius boundary-layer theory to NOB Rayleigh-Benard flow with temperature dependent viscosity and thermal diffusivity. This allows the calculation of the shift of the bulk temperature, the temperature drops across the boundary layers, and the ratio Ï? without introducing any fitting parameter. The calculated quantities are in very good agreement with experiment. When in addition we use the experimental finding that for water the sum of the top and bottom thermal boundary-layer widths (based on the slopes of the temperature profiles at the plates) remains unchanged under NOB effects within experimental resolution, the theory also gives the measured small Nusseltnumber reduction for the NOB case. In addition, it predicts an increase by about 0.5% of the Reynolds number, which is also consistent with the experimental data. By theoretically studying hypothetical liquids with only one of the material parameters being temperature dependent, we shed further light on the origin of NOB corrections in water: While the NOB deviation of x from its OB value Ï? = 1 mainly originates from the temperature dependence of the viscosity, the NOB correction of the Nusselt number primarily originates from the temperature dependence of the thermal diffusivity. Finally, we give the predictions from our theory for the NOB corrections if glycerol is used as operating liquid.
The future of biological diversity in a crowded world (Ernst Mayr Lecture on 29th October 2002)
(2006)
Introduction : The Grants, Dreaming Darwin's Dream ; (Ernst Mayr Lecture am 4. November 2004)
(2006)
The author’s recently published monograph on Alexander von Humboldt' describes the multiple images of this great cultural icon. The book is a metabiographical study that shows how from the middle of the nineteenth century to the present day Humboldt has served as a nucleus of crystallisation for a variety of successive socio-political ideologies, each producing its own distinctive representation of him. The historiographical implications of this biographical diversity are profound and support current attempts to understand historical scholarship in terms of memory cultures.
We expose analogies between turbulence in a fluid heated from below (Rayleigh-Bénard (RB) flow) and shear flows: The unifying theory for RB flow (S.Grossmann and D.Lohse, J.Fluid Mech. 407, 27-56 (2000) and subsequent refinements) can be extended to the flow between rotating cylinders (Taylor-Couette flow) and pipe flow. We identify wind dissipation rates and momentum fluxes that are analogous to the dissipation rate and heat flux in RB flow. The proposed unifying description for the three cases is consistent with the experimental data.
The concept of ecosystem services was developed capitalizing on ecological knowledge that ecosystems perform various functions like increasing or retarding water fluxes, cleansing or polluting water, modifying microclimatic conditions, sustaining or impoverishing biological diversity and so on. There is growing body of ecological knowledge that management of agricultural landscape for its structural diversity is becoming the important pillar of the sustainability of rural areas. Programmes of environmental protection in rural areas should aim not only at introduction environmental friendly technologies of cultivation within farm. They should also be concerned with challenge of how to increase the resistance or resilience of the whole landscape against threats. Recognition of non -commodity effects of diversified agricultural landscape formed by introduction into cultivated fields shelterbelts, stretches of meadows, small mid -field water reservoirs and other biogeochemical barriers provide new options to combine societal demands with environment production. Co -adaptation of human activities with landscape services relies on policy that economic processes should be conformed with ecological processes operating in the region which are enhancing landscape capacities for naturalization of pollution, regeneration of wastes, recycling of water recourses as well as increasing resistance or resilience of the whole system to stresses caused by production of goals required by society. Recognition of system multifunctionality helps to achieve that goal. The knowledge on processes underpinning ecosystem services opened new frontiers for management of landscapes' structures towards enhancing their capacities to deliver requested services. Forests and shelterbelts show similar functions in the landscape but network of shelterbelts perform many similar services like forests growing on smaller part of landscape area. According to studies carried out by Research Centre for Agricultural and Forest Environment in Poland the following functions of shelterbelts are similar to those shown by forests when 4 -5% of the landscape area is under the network of shelterbelts: - modify the microclimatic conditions and heat and water balances; - control the water chemistry composition (control of diffuse pollution); - limit water and wind erosion; - protect the biodiversity; - increase the survival of the game animals; - enhance recreational value of the region; - provide wood and other products; - promote aesthetic values of the countryside. In this review the first four functions of agricultural landscape within Turew neighborhood will be presented.
Psychology's territories - historical and contemporary perspective from different disciplines
(2007)
What determines the territories of psychology? How have the boundaries of psychological research and practice been developed in history, and how might or should they be changed nowadays? This volume presents new approaches to these questions, resulting from a three-year collaboration among internationally known psychologists, neuroscientists, social scientists and historians and philosophers of science from Germany and the United States under the auspices of the Berlin-Brandenburg Academy of Sciences and Humanities. The authors reflect critically on traditional and current views of psychology on the basis of focused historical and contemporary case studies of three broad topic areas: How have psychological concepts been used in disciplines such as psychology, philosophy, or neuroscience, as well as in daily life? Has the use of instruments in psychological research expanded or restricted the discipline’s reach? And how have applications of psychological thinking and research worked in practical contexts? The volume thus presents essays that investigate the separations as well as the interactions between psychology and its neighboring disciplines and, moreover, essays that try to overcome disciplinary distinctions in exemplary ways. The contributions aim to make historical and philosophical studies of psychology relevant to contemporary concerns, and to show how psychology can profit from better interdisciplinary cooperation, thus improving mutual understanding between different scientific cultures.

A reaction to the article „The Lost Archive“, The Wall Street Journal 12.1.2008, page 1 (US edition) http://online.wsj.com/article/SB120008793352784631.html The belief in the myth that old manuscripts should be mysterious and powerful is part and parcel of the age of Modernity. That such expectations were operative in the discussion on the Qumran fragments is still remembered, and more recently the Da Vinci Code, in itself a quite shallow story, sold extremely well. The fact that the Wall Street Journal placed an article on the “lost Bergsträsser-film archive” of Qur’anic manuscripts on its front page on 12th of January seems to be due to the myth of “textual wars” taking place in the world.
The example of Spain illustrates how the production of socio-ecological scales is centred on the social transformation of nature and the construction of socio-ecological and political-ecological scalar gestalts. Concrete geographies, with choreographies of uneven and shifting social power relations, are etched into these ecological, social, political or institutional scalar configurations. These processes are infused with contested and contestable strategies of individuals and social groups, who mobilise spatial scales as part of struggles for control and empowerment, and contest the power geometries of extant scalar gestalts. Needless to say, the mobilisation of scale, the occupation of geographical scale, and the production of scale are central moments in such processes of socio-spatial change. Struggling for the command of scale, or strategizing around excluding particular groups from the performative capabilities of certain scales, shapes social processes, defines relative empowerment and disempowerment and gives rise to very specific socio-spatial relations.
Global change is posing a major challenge to existing forms of natural resource use, socio-economic development and institutional regulation. Although trends such as climate change, socio-economic transformation and institutional change are global in their scope, they have very specific regional outcomes. Regionally distinct coping strategies are required which take into account both the diversity of regional impacts of global change and the local contexts of appropriate responses. This paper explores the impacts of global change on the management of water infrastructure systems in the Berlin-Brandenburg region in terms of three concurrent and overlapping challenges: climate change, socio-economic change and institutional change. It subsequently examines how regional actors in the water sector are addressing these three dimensions of global change.
This special issue of DIE ERDE presents selected key topics discussed within the BBAW working group, including work by group members and invited external researchers, containing nine articles highlighting “Regional Water Challenges” resulting from different kinds of environmental and social changes. We aim to present the complexity of interaction between changes and responses. While the first four articles focus on describing climatic and hydrological changes and their causes, the following five articles focus more on possible mitigation and adaptation measures.

The article informs about historical developments and recent problems in the former wetlands of the Oderbruch, which has been cultivated for agricultural use for 300 years, and in the fen region of the Rhin-Havel-Luch. The periodically inundated floodplains of Oderbruch are characterised by rich-in-clay sedimentation soils, while Rhin-Havel-Luch is a year-round wet fen region with peat soils. In both areas land use necessarily requires an adequate regional water management, employing measures and system solutions for river training, dike construction, drainage and soil cultivation. Options for action and adaptation strategies for the next 20 to 40 years, based on many years of own analyses and case studies, are presented and discussed. The article also considers an aggravation of the problems to be expected from climate change.
Since humans are preferentially settling in flood plains they often influence freshwater systems intensely. The first signs of anthropogenic impacts on surface waters in the Berlin-Brandenburg region are approximately 3000 years old. Considering the multiple and intense human uses of surface waters in this region, we analysed when, how and to which extent regional rivers and streams became impacted by dams, water mills and fish weirs resulting in changes in morphology, hydrology and ecological functioning. We hypothesise that the development and growth of cities in this region necessitated (1) efficient navigability of rivers linking them, (2) efficient use of hydropower resources for mills, and (3) significant pollution of surface waters especially with the beginning of industrial development. We analyse these hypotheses by means of three regional examples and delineate the effects of human uses on selected surface water bodies. Understanding the effects of these historic modifications of surface water supports the identification of options for a sustainable use of surface waters that are currently still subjected to multiple uses but face a significant decrease in discharge due to climate change.
