Continental-scale temperature variability during the past two millennia

Past global climate changes had strong regional expression. To elucidate their spatio-temporal pattern, we reconstructed past temperatures for seven continental-scale regions during the past one to two millennia. The most coherent feature in nearly all of the regional temperature reconstructions is a long-term cooling trend, which ended late in the nineteenth century. At multi-decadal to centennial scales, temperature variability shows distinctly different regional patterns, with more similarity within each hemisphere than between them. There were no globally synchronous multi-decadal warm or cold intervals that define a worldwide Medieval Warm Period or Little Ice Age, but all reconstructions show generally cold conditions between ad 1580 and 1880, punctuated in some regions by warm decades during the eighteenth century. The transition to these colder conditions occurred earlier in the Arctic, Europe and Asia than in North America or the Southern Hemisphere regions. Recent warming reversed the long-term cooling; during the period ad 1971–2000, the area-weighted average reconstructed temperature was higher than any other time in nearly 1,400 years.

Wenn (Schrift-) Worte sich in Bilder einschreiben. Zum mehrstelligen Verhältnis von Wort und Bild

In den Spuren von Elazar Benyoëtz’ dialektischem Aphorismus «Es heißt / ‹du sollst dir kein Bild machen›; / ich male mir aus, was es heißt» stellt sich der Beitrag der Herausforderung, das Recht des Bildes in der Wahrung des Bilderverbots zu retten. Gegenüber dem vor allem in reformierter Tradition zu findenden Vorrang des Wortes vor dem Bild kommt die eigene Macht der Bilder zu zeigen, was Worte nicht sagen können, die ikonische Logik, in den Blick. An Adam Elsheimers «Die drei Marien am Grab» (1603), das Mk 16,1-7(8) gleich doppelt ins Bild setzt – als Inszenierung und als Wort-Zitat auf der Grabplatte – lässt sich ein hochkomplexes Verhältnis von Wort und Bild entdecken. Der Blickwechsel mit diesem Bild im Gespräch mit Martin Luthers Überzeugung von der bildproduktiven Kraft des Evangeliums, wie sie Lukas Cranach d. Ä. auf der berühmten Predella des Reformationsaltars in Wittenberg ausgemalt hat, eröffnen eine Lektüre des ursprünglichen Markusschlusses, die hinter deren letztes Wort (V. 8) zurückgeht und die Lesenden angesichts des leeren Grabes und der es deutenden Botschaft des angelus interpres vor eigene Entscheidungen stellt.

Multi-proxy summer and winter precipitation reconstruction for southern Africa over the last 200 years

This study presents the first consolidation of palaeoclimate proxy records from multiple archives to develop statistical rainfall reconstructions for southern Africa covering the last two centuries. State-of-the-art ensemble reconstructions reveal multi-decadal rainfall variability in the summer and winter rainfall zones. A decrease in precipitation amount over time is identified in the summer rainfall zone. No significant change in precipitation amount occurred in the winter rainfall zone, but rainfall variability has increased over time. Generally synchronous rainfall fluctuations between the two zones are identified on decadal scales, with common wet (dry) periods reconstructed around 1890 (1930). A strong relationship between seasonal rainfall and sea surface temperatures (SSTs) in the surrounding oceans is confirmed. Coherence among decadal-scale fluctuations of southern African rainfall, regional SST, SSTs in the Pacific Ocean and rainfall in south-eastern Australia suggest SST-rainfall teleconnections across the southern hemisphere. Temporal breakdowns of the SST-rainfall relationship in the southern African regions and the connection between the two rainfall zones are observed, for example during the 1950s. Our results confirm the complex interplay between large-scale teleconnections, regional SSTs and local effects in modulating multi-decadal southern African rainfall variability over long timescales.

Three “Bali Deliverables” for more Food Security

As the clock is ticking for a positive outcome at the Ninth WTO Ministerial Conference to be held in Bali in December 2013, agricultural negotiators are scrambling to find solutions to issues such as tariff-rate quota (TRQ) administration and export competition in order to improve trade flows. The main issue seems to be whether WTO rules applying to public stockpiles in developing countries need to be changed or temporarily suspended as a means to enhance national food security. This paper is based on a note submitted to the ICTSD-IPC Expert Group “Meeting on Agriculture and Food Security – Policy Options for MC9 and beyond” (Geneva, June 2013). It lists the policy instruments impacting on global, national and (urban and rural) household food security – “The Food Security Tool Box” – and asks which immediate decisions the WTO Ministers might take in this field despite the political difficulties such as continued agro-dumping practices or the “land grab” issue. Three such “deliverables” are outlined: (i) regional and “virtual” food security schemes could be allowed to provide reserves to other countries without violating the obligation to “form an integral part of a food security programme identified in national legislation” (Agreement on Agriculture, Annex II, para 3); (ii) TRQ under-fills could be improved by mandatory enquiries into low fill rate situations; and (iii) World Food Program (WFP) and other non-commercial food purchases could be exempted from export restrictions and prohibitions. High ambitions for Bali seem to be misplaced. A more realistic yet real progress could restore the dwindling credibility of the WTO as a forum for trade negotiations.

Interactive Segmentation of MR Images from Brain Tumor Patients

Medical doctors often do not trust the result of fully automatic segmentations because they have no possibility to make corrections if necessary. On the other hand, manual corrections can introduce a user bias. In this work, we propose to integrate the possibility for quick manual corrections into a fully automatic segmentation method for brain tumor images. This allows for necessary corrections while maintaining a high objectiveness. The underlying idea is similar to the well-known Grab-Cut algorithm, but here we combine decision forest classification with conditional random field regularization for interactive segmentation of 3D medical images. The approach has been evaluated by two different users on the BraTS2012 dataset. Accuracy and robustness improved compared to a fully automatic method and our interactive approach was ranked among the top performing methods. Time for computation including manual interaction was less than 10 minutes per patient, which makes it attractive for clinical use.

„Extra locos sepulturae“ – Review about finds of newborns inside Roman settlements in present-day Switzerland

Finds of remains of newborns inside Roman settlements are a widespread phenomenon in the Imperium Romanum, including presentday Switzerland. Since the publication of the last review article (Berger 1993) numerous new finds have been made. Therefore it seems important to summarize archaeological and anthropological parameters again, and to re-assess them collectively. During a literature review a total of 262 cases were collected. Similarities as well as differences in the funerary practices become evident. A combination of inhumation, single deposit/grave, and absence of grave goods is the least common denominator in the funerary treatment of individuals who died around the time of birth. However, methods of classical physical anthropology are limited. Histological and biochemical methods are promising and may allow further statements in the future, e.g. with regard to the differentiation between live and still births. In order to evaluate possible correlations between archaeological and anthropological parameters, findings from settlements and cemeteries that are documented in situ as well as a sustainable theoretical framework are required.

Land acquisition, investment, and development in the Lao coffee sector: Successes and failures

Despite the increasing acknowledgment of scholars and practitioners that many large-scale agricultural land acquisitions in developing countries fail or never materialize, empirical evidence about how and why they fail to date is still scarce. Too often, land deals are portrayed as straightforward investments and their success is taken for granted. Looking at the coffee sector in Laos, the authors of this article explore dimensions of the land grab debate that have not yet been sufficiently examined. Coffee concessionaires in southern Laos often fail to use all of the land granted them and fail to produce high yields on the land they do use. Thus, the authors challenge the often-assumed superiority and effectiveness of large-scale versus small-scale production, specifically the argument that they modernize agricultural production and optimize land use. They argue that examining failed investments is as important as studying successful ones for understanding the implications of the land grabbing phenomenon for social, economic, and environmental outcomes. Knowledge about the scale of “failed land deals” provides important motivation for national governments to close the gap between intentions and actual outcomes. This article engages with the current debate on quality of investment and challenges the approach of employing land concessions as a vehicle for economic development in the Lao coffee sector and in other sectors and countries.
