In Alexander von Humboldts Tagebüchern seiner berühmten Forschungsreise durch Spanisch-Amerika finden sich Bemerkungen und Hinweise für künftige Leser seiner Reisedarstellungen zu Problemen der Verpflegung. Zumeist werden Engpässe und Missstände erwähnt sowie Fragen soziopolitischer Situation verdeutlicht. Sie beziehen sich auf Extrembedingungen in stadtfernen Gebieten und im Kontakt mit den indigenen Trägern und Helfern während der einzelnen Exkursionen. Die Darstellungen der alltäglichen Gegebenheiten sind zugleich eine interessante Quelle für Verhaltensmuster der verschiedenen Schichten der spanischkolonialen Gesellschaft wie der Forschungsreisenden, die mit den Schwierigkeiten umzugehen hatten, sich anzupassen verstanden oder ihre eigenen Verhaltensmuster entwickelt haben. Damit ermöglichen Humboldts Aufzeichnungen zugleich auch auf diesem Gebiet manchen Blick auf den seither erfolgten Kulturwandel.
„Wer ist wer?!“

Dieser Beitrag liefert eine historische Übersicht zur Entwicklung des polemischen Diskurses,der sich über zwei Jahrtausende hinweg aus der biblischen Esau/Jakob Narrative bis ins zwanzigste Jahrhundert entwickelt hat. Dabei werden die Bedeutungen einige seiner herausragenden und wenig beachteten Erscheinungen hervorgehoben; besonders die Komödie Jakob und Christian (1937) des deutschen Zionisten Sammy Gronemann (1875–1952). Sie wird im Detail analysiert und gezeigt wie sich durch Gronemann Esau und Jakob in Symbolfiguren des aschkenasischen Judentums und des nationalsozialistischen Deutschtums verwandeln. Gronemanns Innovation besteht darin, dass er mit Hilfe eines rabbinischen Axiom betreffs Purim die überlieferte dichotomische Polarität zwischen Esau und Jakob zugunsten einer humanistischen Menschensicht mittels emphatischer Dialektik auflöst. Dieses exemplarische Phänomen wird eingehend beschrieben, sowie die Rezeption des Stückes in Wien und Tel Aviv.

Im Bachelor-Studiengang (B. Sc.) IT Security an der Fachhochschule St. Pölten wurde im Wintersemester 2011/12 versuchsweise die Lehrorganisation im ersten Fachsemester verändert: Die Module bzw. Teilmodule wurden nicht mehr alle parallel zueinander unterrichtet, sondern jedes Modul wurde exklusiv über einige Wochen abgehalten. Im Beitrag werden die Auswirkungen und bisherigen Erfahrungen mit dieser Reorganisation der Lehre geschildert: So haben sich die Noten im Mittel um etwa eine Note verbessert, die Zahl derjenigen Studierenden, die durch Prüfungen durchfallen, ist drastisch gesunken. Die Zufriedenheit der Studierenden und Lehrenden ist so groß, dass diese Form der Lehrorganisation im gesamten Bachelor- und auch im Masterstudiengang übernommen wird.

Zur Einführung
(2013)
Bereits im 13. Jahrhundert legten die Juden der alten Handelsstadt Frankfurt/Oder ihren Friedhof in der damaligen Dammvorstadt an – und damit ist dieser „Gute Ort“ einer der ältesten jüdischen Begräbnisstätten in Mitteleuropa. Er dokumentiert auf einzigartige Weise sowohl die sehr lange Geschichte der Frankfurter Juden bis zu ihrer gewaltsamen Vernichtung durch die Nazi- Barbarei als auch die des Umgangs der Nachgeborenen mit ihrem Kulturerbe. Der Friedhof, samt Trauerhalle und Gärtnerhäuschen, hatte diesen Weltkrieg im Wesentlichen unbeschadet überstanden.
Several chronometric biases in numerical cognition have informed our understanding of a mental number line (MNL). Complementing this approach, we investigated spatial performance in a magnitude comparison task. Participants located the larger or smaller number of a pair on a horizontal line representing the interval from 0 to 10. Experiments 1 and 2 used only number pairs one unit apart and found that digits were localized farther to the right with "select larger" instructions than with "select smaller" instructions. However, when numerical distance was varied (Experiment 3), digits were localized away from numerically near neighbors. This repulsion effect reveals context-specific distortions in number representation not previously noticed with chronometric measures.
Integrated and concurrent cultures in rice fields are a promising approach to sustainable farming as the demand for aquacultural and agricultural products continues to grow while land and water resources become increasingly scarce. Prawn farming mainly takes place in coastal regions in improved extensive to semi-intensive aquacultures but a trend to shift the industry to inland regions has been noticed. This inland study in Northern Bangladesh used different input regimes such as fertilizer and additional feed to compare the performance of prawn and fish in flooded paddy fields in regard to water quality measurements. Maximal net yields and body weight gain with minimized negative impact on water quality were found when initial body weights of prawn were optimized. Regarding yield factors in reference to the reduction of costs due to the avoidance of expensive fertilizer/feed and effort, prawn performed better than integrated fish cultures considering a higher market value of prawn with net yields of up to 97 +/- 55 kg ha(-1) for unfed and 151 +/- 61 kg ha(-1) for fed treatments. Rice yields of up to 4.7 +/- 0.1 t ha(-1) for unfed and 4.4 +/- 0.1 t ha(-1) were achieved for fed treatments. The findings suggest that for small scale farmers, prawn cum rice cultures are an economically profitable and comparatively easily manageable alternative to rice cum fish cultures.
Two optically obscured Wolf-Rayet (WR) stars have been recently discovered by means of their infrared (IR) circumstellar shells, which show signatures of interaction with each other. Following the systematics of the WR star catalogues, these stars obtain the names WR 120bb and WR 120bc. In this paper, we present and analyse new near-IR, J-, H- and K-band spectra using the Potsdam Wolf-Rayet model atmosphere code. For that purpose, the atomic data base of the code has been extended in order to include all significant lines in the near-IR bands.
The spectra of both stars are classified as WN9h. As their spectra are very similar the parameters that we obtained by the spectral analyses hardly differ. Despite their late spectral subtype, we found relatively high stellar temperatures of 63 kK. The wind composition is dominated by helium, while hydrogen is depleted to 25 per cent by mass.
Because of their location in the Scutum-Centaurus Arm, WR 120bb and WR 120bc appear highly reddened, A(Ks) approximate to 2 mag. We adopt a common distance of 5.8 kpc to both stars, which complies with the typical absolute K-band magnitude for the WN9h subtype of -6.5 mag, is consistent with their observed extinction based on comparison with other massive stars in the region, and allows for the possibility that their shells are interacting with each other. This leads to luminosities of log(L/L-circle dot) = 5.66 and 5.54 for WR 120bb and WR 120bc, with large uncertainties due to the adopted distance.
The values of the luminosities of WR 120bb and WR 120bc imply that the immediate precursors of both stars were red supergiants (RSG). This implies in turn that the circumstellar shells associated with WR 120bb and WR 120bc were formed by interaction between the WR wind and the dense material shed during the preceding RSG phase.
Management of data to produce scientific knowledge is a key challenge for biological research in the 21st century. Emerging high-throughput technologies allow life science researchers to produce big data at speeds and in amounts that were unthinkable just a few years ago. This places high demands on all aspects of the workflow: from data capture (including the experimental constraints of the experiment), analysis and preservation, to peer-reviewed publication of results. Failure to recognise the issues at each level can lead to serious conflicts and mistakes; research may then be compromised as a result of the publication of non-coherent protocols, or the misinterpretation of published data. In this report, we present the results from a workshop that was organised to create an ontological data-modelling framework for Laboratory Protocol Standards for the Molecular Methods Database (MolMeth). The workshop provided a set of short- and long-term goals for the MolMeth database, the most important being the decision to use the established EXACT description of biomedical ontologies as a starting point.
We tested the limits of working-memory capacity (WMC) of young adults, old adults, and children with a memory-updating task. The task consisted of mentally shifting spatial positions within a grid according to arrows, their color signaling either only go (control) or go/no-go conditions. The interference model (IM) of Oberauer and Kliegl (2006) was simultaneously fitted to the data of all groups. In addition to the 3 main model parameters (feature overlap, noise, and processing rate), we estimated the time for switching between go and no-go steps as a new model parameter. In this study, we examined the IM parameters across the life span. The IM parameter estimates show that (a) conditions were not different in interference by feature overlap and interference by confusion; (b) switching costs time; (c) young adults and children were less susceptible than old adults to interference due to feature overlap; (d) noise was highest for children, followed by old and young adults; (e) old adults differed from children and young adults in lower processing rate; and (f) children and old adults had a larger switch cost between go steps and no-go steps. Thus, the results of this study indicated that across age, the IM parameters contribute distinctively for explaining the limits of WMC.

Deserts are a major source of loess and may undergo substantial wind-erosion as evidenced by yardang fields, deflation pans, and wind-scoured bedrock landscapes. However, there are few quantitative estimates of bedrock removal by wind abrasion and deflation. Here, we report wind-erosion rates in the western Qaidam Basin in central China based on measurements of cosmogenic Be-10 in exhumed Miocene sedimentary bedrock. Sedimentary bedrock erosion rates range from 0.05 to 0.4 mm/yr, although the majority of measurements cluster at 0.125 +/- 0.05 mm/yr. These results, combined with previous work, indicate that strong winds, hyper-aridity, exposure of friable Neogene strata, and ongoing rock deformation and uplift in the western Qaidam Basin have created an environment where wind, instead of water, is the dominant agent of erosion and sediment transport. Its geographic location (upwind) combined with volumetric estimates suggest that the Qaidam Basin is a major source (up to 50%) of dust to the Chinese Loess Plateau to the east. The cosmogenically derived wind erosion rates are within the range of erosion rates determined from glacial and fluvial dominated landscapes worldwide, exemplifying the effectiveness of wind to erode and transport significant quantities of bedrock.

Matrix product states and their continuous analogues are variational classes of states that capture quantum many-body systems or quantum fields with low entanglement; they are at the basis of the density-matrix renormalization group method and continuous variants thereof. In this work we show that, generically, N-point functions of arbitrary operators in discrete and continuous translation invariant matrix product states are completely characterized by the corresponding two- and three-point functions. Aside from having important consequences for the structure of correlations in quantum states with low entanglement, this result provides a new way of reconstructing unknown states from correlation measurements, e. g., for one-dimensional continuous systems of cold atoms. We argue that such a relation of correlation functions may help in devising perturbative approaches to interacting theories.
In this article, we propose a model for an understanding process that learners can use while studying programming. We focus on the “small step” method, in which students learn only a few concepts for one program to avoid having trouble with learning programming. We also analyze the difference in the description order between several C programming textbooks on the basis of the model. We developed a tool to detect “gaps” (a lot of concepts to be learned in a program) in programming textbooks.
A survey has been carried out in the Computer Science (CS) department at the University of Baghdad to investigate the attitudes of CS students in a female dominant environment, showing the differences between male and female students in different academic years. We also compare the attitudes of the freshman students of two different cultures (University of Baghdad, Iraq, and the University of Potsdam).
In this paper we report on our experiments in teaching computer science concepts with a mix of tangible and abstract object manipulations. The goal we set ourselves was to let pupils discover the challenges one has to meet to automatically manipulate formatted text. We worked with a group of 25 secondary school pupils (9-10th grade), and they were actually able to “invent” the concept of mark-up language. From this experiment we distilled a set of activities which will be replicated in other classes (6th grade) under the guidance of maths teachers.
The preference for fruits and vegetables is the main predictor for the longtime healthy eating behavior. There are many factors which affect the development of food preferences. The familiarity with different foods seems to be a special aspect associated with the corresponding preference. To establish a preference for fruits and vegetables during early childhood, we need to know more about the factors that affect this preference development. So far, research has mostly concentrated on the food intake and less on the corresponding preference. Additionally, it is often based on studies of the mere-exposure effect or on older children and their ability to label fruits and vegetables correctly. Findings about the level of food familiarity in young children and its relation to the actual food preference are still missing. Our study focuses on different aspects of food familiarity as well as on their relationship to the child's preference and presents results from 213 children aged 2 to 10 years. Using standardized photos, the food preference was measured with a computer-based method that ran automatically without influence from parents or interviewer. The children knew fewer of the presented vegetables (66 %) than fruits or sweets (78 % each). About the same number of vegetables (63 %) had already been tasted by the children and were considered tasty. Only 48 % of the presented vegetables were named correctly - an ability that increases in older children. Concerning the relationship between the familiarity with vegetables and their preference, the different familiarity aspects showed that vegetables of lower preference were less often recognized, tasted, considered tasty, or named correctly.
We know exactly what you want the development of a completely individualised conjoint analysis
(2013)
Improving the predictive validity of conjoint analysis has been an important research objective for many years. Whereas the majority of attempts have been different approaches to preference modelling, data collection or product presentation, only a few scholars have tried to improve predictive validity by individualising conjoint designs. This comes as a surprise because many markets have observed an augmented demand for customised products and highly heterogeneous customers' preferences. Against this background, the authors develop a conjoint variant based on a completely individualised conjoint design. More concretely, the new approach not only individualises the attributes, but also the attribute levels. The results of a comprehensive empirical study yield a significantly higher validity than existing standardised-level conjoint approaches. Consequently, they help marketers to gain deeper insights into their customers' preferences.
The dynamics of external contributions to the geomagnetic field is investigated by applying time-frequency methods to magnetic observatory data. Fractal models and multiscale analysis enable obtaining maximum quantitative information related to the short-term dynamics of the geomagnetic field activity. The stochastic properties of the horizontal component of the transient external field are determined by searching for scaling laws in the power spectra. The spectrum fits a power law with a scaling exponent beta, a typical characteristic of self-affine time-series. Local variations in the power-law exponent are investigated by applying wavelet analysis to the same time-series. These analyses highlight the self-affine properties of geomagnetic perturbations and their persistence. Moreover, they show that the main phases of sudden storm disturbances are uniquely characterized by a scaling exponent varying between 1 and 3, possibly related to the energy contained in the external field. These new findings suggest the existence of a long-range dependence, the scaling exponent being an efficient indicator of geomagnetic activity and singularity detection. These results show that by using magnetogram regularity to reflect the magnetosphere activity, a theoretical analysis of the external geomagnetic field based on local power-law exponents is possible.
The expansion and intensification of soya bean agriculture in southeastern Amazonia can alter watershed hydrology and biogeochemistry by changing the land cover, water balance and nutrient inputs. Several new insights on the responses of watershed hydrology and biogeochemistry to deforestation in Mato Grosso have emerged from recent intensive field campaigns in this region. Because of reduced evapotranspiration, total water export increases threefold to fourfold in soya bean watersheds compared with forest. However, the deep and highly permeable soils on the broad plateaus on which much of the soya bean cultivation has expanded buffer small soya bean watersheds against increased stormflows. Concentrations of nitrate and phosphate do not differ between forest or soya bean watersheds because fixation of phosphorus fertilizer by iron and aluminium oxides and anion exchange of nitrate in deep soils restrict nutrient movement. Despite resistance to biogeochemical change, streams in soya bean watersheds have higher temperatures caused by impoundments and reduction of bordering riparian forest. In larger rivers, increased water flow, current velocities and sediment flux following deforestation can reshape stream morphology, suggesting that cumulative impacts of deforestation in small watersheds will occur at larger scales.

Vom Symbol zum Schweigen
(2013)
Die christliche Kabbala des deutschen Humanisten Johannes Reuchlin ist entscheidend von seiner Vorstellung vom Wesen und von der Funktion des Symbols bestimmt. Dieser Beitrag sucht nach dem Ursprung von Reuchlins Symbolbegriff und stellt die These auf, dass Dionysius Pseudo-Areopagitas Bemerkungen über eine symbolica theologia Reuchlins Sicht auf die jüdische Mystik grundlegend beeinflusste. Darüber hinaus wird die Frage diskutiert, ob Reuchlins Idee von einer symbolischen Theologie, die auch in der modernen Forschung fortwirkt, den frühen Kabbalisten tatsächlich gerecht wird, oder ob Reuchlins Rezeption nicht vielmehr einer neuplatonischen Literatur geschuldet ist, die den jüdischen Mystikern überhaupt nicht zugänglich war.
Anhand von Beispielen aus der sephardischen Presse und aus Übersetzungen von deutschsprachigen Werken wird der Frage nachgegangen, wie Orts- und Personennamen aus dem deutschen Sprachraum im späten 19. und frühen 20. Jahrhundert in das judenspanische Sprach- und Schriftsystem transferiert wurden. Dabei zeigt sich, dass der Ort der Publikation eine entscheidende Rolle spielte. Während in Wiener Publikationen im Allgemeinen die Transkription der Namen gemäß der deutschen Aussprache bevorzugt wird, macht sich in Drucken aus anderen Städten der Einfluss von Mittlersprachen bemerkbar. Mit zunehmender Entfernung und abnehmender Kenntnis der deutschen Sprache und Realität nehmen außerdem die Druckfehler deutlich zu, so dass das Entziffern und Identifizieren von deutschen Namen in judenspanischen Texten zuweilen einem Detektivspiel gleicht.
