Challenges of metarepresentation to translation competence.

One of the outcomes of the inferential framework of communication developed by Sperber and Wilson (1995) is the pursuit of competence-oriented research on translation (CORT), as proposed in Gutt 2000. CORT focuses on the discovery of the mental capabilities involved in the translation task.\ud \ud One of the key concepts recently being explored in the inferential framework is that of metarepresentation. It involves the capability of people to represent in their minds not only the external world but the thoughts (mental representations) other people entertain about that world. Metarepresentations can involve several levels of embedding: thus persons can metarepresent to themselves the thoughts of others about their own thoughts about a certain subject matter etc.\ud \ud While metarepresentation is an important mental faculty for successful communication in general, it is of eminent importance in the translation task where the translator may have to metarepresent several different worlds of thoughts (cognitive environments) and their interaction with one another as mutual cognitive environments in cross-cultural communication events.\ud \ud This paper first briefly outlines the inferential model of translation, including the notions of cognitive environment, context and metarepresentation. The main part of the paper surveys five distinct constellations of mutual cognitive environments found in translation situations. The first – and ideal – constellation is where original author, translator and receptor audience all share essentially the same mutual cognitive environment. More commonly, however, this condition is not fulfilled and the other four constellations can present considerable challenges to the metarepresentational capabilities of the translator. Furthermore, the translator needs to develop strategies that will overcome differences in cognitive environment that would negatively affect the communication process. (This is in addition to the task of overcoming problems caused by language differences.) Suggestions are made about directions in which these problems, which can seriously undermine the success of the translated text, can be sought.\ud \ud References\ud Gutt, Ernst-August 2000 Translation and relevance: Cognition and context.

Mit der Röntgenstrukturanalyse Strukturen knacken : Motor der Wirkstoff-Entwicklung

Chemiker stehen in ihrer Mentalität Architekten nahe: Sie planen und bauen Moleküle. Schon lange, bevor der atomare Aufbau der Materie experimentell bewiesen war, entwickelten sie genaue Vorstellungen über die Raumstruktur von Molekülen. Erst zu Beginn des 20.Jahrhunderts wurden diese "Arbeitshypothesen" – zum Beispiel das von Jacobus van’t Hoff postulierte Tetraedermodell für den vierbindigen Kohlenstoff – von den Physikern glänzend bestätigt. Zwar ist es mittlerweile möglich, die Struktur von unbekannten Molekülen zuverlässig vorherzusagen; doch nach wie vor sind genaue experimentelle Strukturbestimmungen ein unverzichtbarer Bestandteil vieler Forschungsprojekte

Elliptic flow in Au+Au collisions at sqrt sNN = 130 GeV

Elliptic flow from nuclear collisions is a hadronic observable sensitive to the early stages of system evolution. We report first results on elliptic flow of charged particles at midrapidity in Au+Au collisions at sqrt[sNN] = 130 GeV using the STAR Time Projection Chamber at the Relativistic Heavy Ion Collider. The elliptic flow signal, v2, averaged over transverse momentum, reaches values of about 6% for relatively peripheral collisions and decreases for the more central collisions. This can be interpreted as the observation of a higher degree of thermalization than at lower collision energies. Pseudorapidity and transverse momentum dependence of elliptic flow are also presented.alle Autoren: K. H. Ackermann19, N. Adams28, C. Adler12, Z. Ahammed27, S. Ahmad28, C. Allgower13, J.

Multisensory causal inference in the brain

At any given moment, our brain processes multiple inputs from its different sensory modalities (vision, hearing, touch, etc.). In deciphering this array of sensory information, the brain has to solve two problems: (1) which of the inputs originate from the same object and should be integrated and (2) for the sensations originating from the same object, how best to integrate them. Recent behavioural studies suggest that the human brain solves these problems using optimal probabilistic inference, known as Bayesian causal inference. However, how and where the underlying computations are carried out in the brain have remained unknown. By combining neuroimaging-based decoding techniques and computational modelling of behavioural data, a new study now sheds light on how multisensory causal inference maps onto specific brain areas. The results suggest that the complexity of neural computations increases along the visual hierarchy and link specific components of the causal inference process with specific visual and parietal regions

Evidence for an exotic S=-2, Q=-2 baryon resonance in proton-proton collisions at the CERN SPS

Results of resonance searches in the Xi - pi -, Xi - pi +, Xi -bar+ pi -, and Xi -bar+ pi + invariant mass spectra in proton-proton collisions at sqrt[s]=17.2 GeV are presented. Evidence is shown for the existence of a narrow Xi - pi - baryon resonance with mass of 1.862±0.002 GeV/c2 and width below the detector resolution of about 0.018 GeV/c2. The significance is estimated to be above 4.2 sigma . This state is a candidate for the hypothetical exotic Xi --3/2 baryon with S=-2, I=3 / 2, and a quark content of (dsdsu-bar). At the same mass, a peak is observed in the Xi - pi + spectrum which is a candidate for the Xi 03/2 member of this isospin quartet with a quark content of (dsusd-bar). The corresponding antibaryon spectra also show enhancements at the same invariant mass

Impact assessment of agricultural innovations: a review

The current conditions of the markets and favorable policies, as well as the progress of science and communications, are promoting further development and diffusion of agricultural innovations, which have effects on different areas of agrarian development. The objective of this paper is to present a review of characteristics of agricultural innovations and their diffusion, adoption and impacts, as well as an update of the types and methods of assessment. Agricultural innovations are not only new or improved products, they are also models and systems, and should have a positive social effect. Innovation areas in developing countries are more concentrated on production and distribution, whereas developed countries concentrate on offering inputs. Investments from the private sector in agricultural innovations are growing faster than those from the public sector. The adoption of innovations is medium-term, and usually less than 100%. The impact of innovations includes intermediate areas, such as institutional, political, scientific and productive areas. The economic efficiency of the investment in innovations is the most often mentioned purpose of impact assessments in the literature. The efficiency analysis (ex-post) and its surplus approach is still the most used method for assessing impact of agricultural innovations. Nevertheless, other goals are becoming more important, such as food security, environmental protection and poverty reduction. Livelihood, comprehensive and multidimensional approaches go beyond the economic approach. Moreover, specific models with advantages of prognosis and improved precision are replacing or complementing the classic socio-economic approach
