Emergence, analysis and optimization of structures - Concepts and strategies across disciplines
(2007)
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.
Ancient Greek philosophers were the first to postulate the possibility of explaining nature in theoretical terms and to initiate attempts at this. With the rise of monotheistic religions of revelation claiming supremacy over human reason and envisaging a new world to come, studies of the natural order of the transient world were widely considered undesirable. Later, in the Middle Ages, the desire for human understanding of nature in terms of reason was revived. This article is concerned with the fundamental reversal of attitudes, from “undesirable” to “desirable”, that eventually led into the foundations of modern science. One of the earliest, most ingenious and most interesting personalities involved was Eriugena, a theologian at the Court of Charles the Bald in the 9th century. Though understanding what we call nature is only one of the several aspects of his theological work, his line of thought implies a turn into a pro-scientific direction: the natural order is to be understood in abstract terms of ‘primordial causes’; understanding nature is considered to be the will of God; man encompasses the whole of creation in a physical as well as a mental sense. Basically similar ideas on the reconciliation of scientific rationality and monotheistic religions of revelation were conceived, independently and nearly simultaneously, by the Arab philosopher al-Kindi in Bagdad. Eriugena was more outspoken in his claim that reason is superior to authority. This claim is implicit in the thought of Nicholas of Cusa with his emphasis on human mental creativity as the image of God’s creativity; and it is the keynote of Galileo’s ‘Letter to the Grand Duchess Christina’ some 800 years later, the manifesto expressing basic attitudes of modern science. This article in English is based on the monography (in German): A. Gierer “Eriugena, al-Kindi, Nikolaus von Kues - Protagonisten einer wissenschaftsfreundlichen Wende im philosophischen und theologischen Denken”, Acta Historica Leopoldina 29 (1999), Barth Verlag in MVH Verlage Heidelberg, ISBN: 3-335-00652-6
Even a reductionist attempt to define scholarship is clearly fraught with difficulty, but an idealised historical lexicographer-cum-scholar must obviously have – inter alia and at the very least – a profound linguistic and textual knowledge of the language being documented, an ability to understand texts in their historical context and to analyse the meaning or function of lexical items as used in context, an ability to synthesise the results through generalisation and abstraction and to formulate them in a way that is both accurate, i.e. reflects actual usage, and user- or reader-friendly, i.e. is comprehensible to the user/reader. S/he must have encyclopedic or world knowledge and literary skills in order to understand general content words and explain their meaning and their semantic shifts perhaps over many centuries, and technical expertise to understand specialist terms and define their use in specific contexts, again perhaps over time. In respect of etymology s/he must not only have knowledge of older stages of the language and an ability to reconstruct unattested forms, but also knowledge of the other languages that have impacted on the language being documented, or at least familiarity with the scholarly historical dictionaries of those languages. That is a tall order indeed, impossibly tall for any one person today given today‘s demands on and expectations of lexicographers. Teams which include specialists in different areas or at least have access to consultants in such areas alongside generalists are needed if scholarly standards are to be met. The standard of scholarship is primarily a factor of the number and range as well as the knowledge and experience of the lexicographers, as is in large measure the pace of production. In this regard, it cannot be emphasised enough that scholarly historical lexicography of high quality is and will remain very time consuming.

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).
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.
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.
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.
From exclusion to inclusion : improving clinical research in vulnerable populations ; memorandum
(2014)
Therapeutic care for vulnerable populations – meaning patient groups such as underage children and the mentally ill that have limited or no capacity for giving informed consent – is severely lacking. Thus, for example, a great portion of pharmaceuticals used in the treatment of children and youth have not been specifically designed for these groups, which often results in side effects that are disproportionate to those associated with such medicines when used by adults. Moreover, vulnerable populations are at times faced with having no therapies at all for some of their ailments, such that children and dementia sufferers, for example, are often considered to be “therapeutic orphans”. It is therefore urgent that clinical research be carried out among vulnerable populations in order to improve their therapeutic possibilities. The Clinical Research on Vulnerable Populations Research Group – a cooperative effort between the Berlin-Brandenburg Academy of Sciences and Humanities (Berlin, Germany) and the European Academy of Technology Assessment (Bad Neuenahr, Germany) – has set itself the task of analyzing the state of clinical research on vulnerable populations so as to be able to develop suggestions for improving future research of this kind. The results of this work are presented in the following memorandum, which seeks to portray the state-of-the-art in this domain while also assessing the strengths and weaknesses of contemporary ethical and medical perspectives related to it. The memorandum is primarily oriented towards those in the relevant scientific disciplines who can benefit from obtaining an informed consensus regarding the current state of the discussions taking place around this topic.
