The short paper introduces the concept of possible branches of double-stranded DNA (later sometimes called palindromes): Certain sequences of nucleotides may be followed, after a short unpaired stretch, by a complementary sequence in reversed order, such that each DNA strand can fold back on itself, and the DNA assumes a cruciform or tree-like structure. This is postulated to interact with regulatory proteins.
The climate change debate has increased the need for knowledge on both long- and short-term regional environmental changes. In general, these changes may often be a product of multiple causes, which complicates the separation of single driving forces. In this review we focus on current water budget changes in Germany’s capital region, Berlin-Brandenburg, over the last 30 years. Available studies from a variety of disciplines (e.g. hydrology, water engineering, landscape ecology, nature conservation) were analysed in order to (1) identify both local and regional hydrological changes, (2) reveal their potential causes, and (3) discuss responses of ecosystems and society. These studies show that the Berlin-Brandenburg region is widely characterised by decreasing groundwater recharge, leading to decreasing groundwater and lake levels as well as decreasing fluvial discharge. These trends result both from complex, regional human impacts (e.g. long-term effects of hydro-melioration and changes in forest composition) and more general climate warming. The observed and assumed (future) changes of the regional water balance have been creating, and will continue to create, multifaceted impacts on existing ecosystems and society (e.g. wetland drying, decrease of biodiversity, decrease of productivity of grasslands and forests, increasing conflicts of interests). Several efforts to respond to the regional water deficit problem have already been undertaken, comprising for instance land-use optimisation, wetland restoration measures and the reestablishment of mixed deciduous forests. In general, however, the reviewed regional material on this topic reveals that the number and complexity of empirical studies are still poor. Thus, for both the identification and the explanation of current water balance changes and their effects, as well as for development and implementation of adaptive strategies, further multidisciplinary research efforts at different scales, including interregional comparisons, are required. Furthermore, both the observation of hydrological changes and the evaluation of adaptive and mitigative responses require at least continuous or, even better, extended monitoring efforts.
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.
Für Schleiermacher ist Religion keine pädagogisch nützliche Mischung von Metaphysik und Moral, sondern eine eigene Dimension des Menschseins, Anschauung des Universums, Sinn und Geschmack fürs Unendliche; die von der Aufklärung favorisierte „natürliche Religion“ der allgemeinen, übergeschichtlichen Vernunftwahrheiten sei bloß eine Totgeburt, jede wirkliche, lebendige Religion dagegen eine unableitbare geschichtliche Individualität. Im Christentum sei Jesus Christus die Zentralgestalt, der Vermittler und Versöhner des Zwiespalts zwischen Endlichem und Unendlichem, an dem sich alle Religion abarbeite. Im Laufe seiner Entwicklung strebe das Christentum immer mehr zu Sozialgestalten ohne Hierarchie zwischen Priestern und Laien; in der Vollendung (den aber selbst der Protestantismus noch nicht erreicht habe) würden alle „von Gott gelehrt“ sein (Johannes 6,45).
Der theologische Rationalismus war die letzte Gestalt der Aufklärungstheologie; seine Blütezeit erlebte er gleichzeitig und in Konkurrenz mit der u.a. von Schelling geprägten spekulativen Richtung und mit der teils mehr biblizistischen, teils mehr konfessionellen Theologie der Erweckung. Kennzeichen des Rationalismus war einerseits eine verstärkte historisch-kritische Quellenforschung, andererseits das Bemühen, Lehre und Praxis soweit möglich auf das auszurichten, was jenseits geschichtlicher Autoritäten der allgemeinen menschlichen Vernunft plausibel sei: die Existenz Gottes, die Unsterblichkeit der Seele und die Pflicht zu tugendhaftem Leben. Seit etwa 1840 verfiel der Rationalismus.
The neuronal dynamics of auditory language comprehension : (Akademievorlesung am 12. November 1998)
(1999)
With the present report the Berlin-Brandenburg Academy of Sciences and Humanities wants to draw attention to the results of one of its interdisciplinary projects, which are published elsewhere in more detail. The authors believe that their particular approach to the subject of "waste energy recovery", in combination with an interdisciplinary perspective, suggests a new way of discussing energy problems that has the potential to lead to qualified statements...
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 present study explores whether regional water resources can be used more efficiently by Brandenburg’s farming systems. A description of agriculture in Brandenburg today is followed by a systematic analysis of measures to raise the water efficiency. Brandenburg’s agricultural systems are divided into three sections: soil, plant production and livestock farming. Within these sections measures to increase water efficiency are listed and analysed with reference to five objective criteria for raising water use efficiency. In view of the complexity of farming systems in Brandenburg, general measures to raise water use efficiency could not be derived. Site-specific tillage practices and crop patterns adjusted to recent weather conditions may reflect the specific diversity of Brandenburg more efficiently.
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.
Historic parks and gardens survive in many places with some sites still in use but others abandoned long ago and now given over to other purposes. Accurate repair and reliable reconstruction depend upon archaeological information which is particularly vulnerable to the effects of climate change. The impairment and loss of such detail threaten historical integrity. This means that we must monitor changes and develop suitable mitigation.
Global climate change and aspects of regional climate change in the Berlin-Brandenburg region
(2011)
To obtain an estimate of the average temperature of the northern hemisphere during the last 1200 years, proxy data have been merged with instrumental recordings. These instrumental measurements are, with a few exceptions, only available for the recent 150 years. In the city of Berlin the temperature has been recorded since as early as 1701. However, during the first 150 years the measurements were problematic as location, measurement procedure and instruments changed frequently and without proper documentation. From 1847 onwards observations became more reliable once the Royal Prussian Meteorological Institute had been established. For the last 100 years temperature and precipitation measurements have been performed in parallel at Berlin-Dahlem and Potsdam. The datasets recorded in the city of Berlin and in Berlin-Dahlem have been merged to obtain a record of more than 300 years. It indicates that the temperature of Berlin has risen by 1.04°C during the last 100 years after correcting for the urbanisation effect. In the same period, the total number of frost days has significantly decreased by almost 17 days, and the number of summer days has significantly increased by about 12 days. Annual mean precipitation has hardly changed (decrease less than 0.2 %) during the last century. However, rainfall has decreased by about 4 % in summer and increased by 3 % in winter. All precipitation changes are below the 95 % ignificance level. Model projections indicate that warming will continue which means that Berlin-Brandenburg will experience a temperature rise of about 3-3.5°C by the end of this century for the IPCC scenario A1B. For the same scenario precipitation is expected to increase by 10-20 % in winter and to decrease by 10-30 % in summer: The seasonal precipitation changes compensate each other resulting in an almost unchanged annual mean.
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.

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.
The computer has come to play a transformative role in the ways we model, store, process and study text. Nevertheless, we cannot yet claim to have realised the promises of the digital medium: the organisation and dissemination of scholarly knowledge through the exchange, reuse and enrichment of data sets. Despite the acclaimed interdisciplinary nature of digital humanities, current digital research takes place in a closed environment and rarely surpasses the traditional boundaries of a field. Furthermore, it is worthwhile to continue questioning the models we use and whether they are actually suitable for our scholarly needs. There’s a risk that the affordances and limitations of a prevailing model may blind us to aspects it doesn’t support.
In her talk, Elli Bleeker discusses different technologies to model data with respect to their expressive power and their potential to address the needs of the scholarly community. Within this framework, she introduces a new data model for text, Text-As-Graph (TAG), and it’s reference implementation Alexandria, a text repository system. The TAG model allows researchers to store, query, and analyse text that is encoded from different perspectives. Alexandria thus stimulates new ways of looking at textual objects, facilitates the exchange of information across disciplines, and secures textual knowledge for future endeavours. From a philosophical perspective, the TAG model and the workflow of Alexandria raise compelling questions about our notions of textuality, and prompt us to reconsider how we can best model the variety of textual dimensions.
Responding to the Antique : a rediscovered Roman Circus Sarcophagus and its Renaissance Afterlife
(2005)
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.
For a fistful of blogs: Discovery and comparative benchmarking of republishable German content
(2014)
We introduce two corpora gathered on the web and related to computer-mediated communication: blog posts and blog comments. In order to build such corpora, we addressed following issues: website discovery and crawling, content extraction constraints, and text quality assessment. The blogs were manually classified as to their license and content type. Our results show that it is possible to find blogs in German under Creative Commons license, and that it is possible to perform text extraction and linguistic annotation efficiently enough to allow for a comparison with more traditional text types such as newspaper corpora and subtitles. The comparison gives insights on distributional properties of the processed web texts on token and type level. For example, quantitative analysis reveals that blog posts are close to written language, while comments are slightly closer to spoken language.

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.

The birth of rules
(2001)
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.
In 20 articles experts from research, politics and research management discuss current challenges and future advancements of European research infrastructures for the humanities and social sciences, particularly in view of the funding scheme Horizon 2020 and the ESRFI Roadmap update. Starting with an overview of SSH infrastructures it elaborates on four specific areas that increasingly demand a pan-European approach. Drawing from the SSH infrastructure projects´ experience, it then (re-) defines the requirements and potential for next generation infrastructure projects. They highlight the developments and problems they anticipate, focussing in particular on advancing digitalisation in the SSH. The book draws together the insights gained at a conference of the same name, “Facing the Future”, held in Berlin in November 2013. The conference was attended by 70 experts from 19 European countries who met to discuss the new challenges posed by the increasing necessity of integrating digital research tools into everyday working life. It was organised by the European Strategy Forum on Research Infrastructures (ESFRI), the federation of All European Academies (ALLEA), the Union of the German Academies of Sciences and Humanities, and the German Data Forum. It took place as part of a project financed by the German Federal Ministry of Education and Research (BMBF) entitled Survey and Analysis of Basic Research in the Social Sciences and Humanities in Europe (SASSH).
The African European Mediterranean Academies for Science Education (AEMASE) initiative is committed to promoting science outreach to society and to improving the quality and accessibility of science education in schools throughout the eponymous North-South region. To achieve these aims, one of AEMASE’s key activities is implementing IBSE in more schools and supporting the continued professional development of science educators in IBSE methodology and practice. In the long term, the AEMASE partner institutions, which come from all three geographical areas, seek to contribute to the steady development of quality science and innovation systems by focussing on stimulating and supporting the future generations of researchers and innovators. In this context, key AEMASE partner institutions held an international conference on science education in Rome in May 2014, hosted by the venerable Accademia Nazionale dei Lincei. Participants from six continents shared their professional experiences with IBSE and discussed best practices, challenges and future collaboration opportunities. The conference brought together representatives from three crucial areas of expertise: science, education, and policy. The outcomes of this conference are condensed in the report which serves as a testament to the relevance and importance of quality science education for modern societies.
The current debates on the demographic transformation have been characterised on the one hand by declining birth rates and on the other by increasing life expectancy. Such debates usually focus on the consequences for society, which are frequently described in dark terms. In this booklet, by contrast, you will find analyses and suggestions on how to improve the situation of children and parents to make it easier to realise the desire to have children.

Single-cell analyses comprise a multitude of analytical methods that share a common feature, namely the focus on individual cells. This is in contrast to previous methods that provided summarized data for cell clusters, groups of cells, tissues and organs. The new field offers huge potential not only for basic research, but also for medical and biotechnological applications, as it opens up new levels in the context-related and personal interpretation of biological interconnections. This brochure on single-cell analysis provides an overview on the new possibilities from the viewpoint of developmental biology, biomedicine and bioinformatics, but also addresses possible social im-plications and consequences.
Based on the social challenges of our time, this statement addresses key aspects of the question of how the work of tomorrow can be redesigned. On behalf of the Standing Committee of the German National Academy of Sciences and under the leadership of the Berlin-Brandenburg Academy of Sciences and Humanities, the authors have intensively examined the current structural change in the world of work. They suggest that the concept of work should be interpreted broadly and that gainful employment should be considered in its interplay with other forms of activity. Non-market-related activities such as citizen work, care work and political work and their interplay are also taken into consideration. The shift in emphasis from a "work-oriented society" to an "activity-oriented society" highlights the opportunities that open up for people, the economy and society if these activities are equally recognized.
