Digital multitext editions from scratch to electronic performance. Transcription and collation routines transformed in a flexible database system

The poster demonstrates the preparatory steps of a digital multi-text edition that are abstracted from the experiences made in the Parzival Project, based at the University of Bern, the Berlin-Brandenburg Academy of Sciences and the University of Erlangen. This edition of Wolfram von Eschenbach’s German Grail novel, written shortly after 1200 and transmitted during several centuries in ca. hundred witnesses, has now been completed by more than a half of the textual corpus. As the text is transmitted in medieval manuscripts the witnesses have to be transcribed according to specific encoding rules. The transcriptions then are collated following certain ideas and concepts of how the transmission process could have developed. The transcriptions and collations finally have to be transferred to a digital edition that allows the users to explore the characteristics of single witnesses as well as the history of a text, which is delivered in variants and in different versions. A dynamically organized database offering various components and adapted to the needs of diverse user-profiles is nowadays the right tool for this purpose.

Chrétiens ›Roman de Perceval ou le Conte du Graal‹ und Wolframs ›Parzival‹. Ihre Überlieferung und textkritische Erschließung

This article discusses the manuscript transmission of Chrétien’s Roman de Perceval ou le Conte du Graal and Wolfram’s Parzival in terms of their textual tradition and editorial criticism. It shows that the most recent edition of the Old French Perceval (K. Busby 1993) can be viewed as a landmark of the art of conventional editing that appeared at the peak of the discussion of ‘New Philology’ and took its own position in this context. At the same time, the Perceval was subject of critical studies based on the principle of ‘unrooted trees’ that questioned the genealogical concept of traditional ‘Lachmannian’ stemmatology. Conversely, a new edition of Wolfram’s Parzival, based on all known manuscripts, remained a desideratum for decades in German studies. Specific research on the textual tradition played a rather marginal role for a long time, but has been reinforced in the recent years in the context of a new critical edition presenting the totality of manuscripts as well as different textual versions in electronic form. The concept of ‘unrooted trees’ visualizing relationships of manuscript readings can be integrated in this concept. The article gives an overview of these methods, presents examples of editorial techniques, and develops ideas on how to combine the research on the manuscript tradition of both the German text and its French counterpart.

Copying, emergence, and digital reproduction

This talk combines concepts of the copying of manuscripts in the age before mechanical reproduction (as described in W. Benjamin’s famous Artwork-essay), of the emergence of non-vertical evolution (as to be found in textual ‘contamination’ and in horizontal gene transfer alike), and of the electronic reproduction of such phenomena (as presented in scholarly digital editions and phylogenetic trees). The guiding idea is that ‘copying’, ‘emergence’, and ‘(digital) reproduction’ enable variation depending on particular physical or biological forms, on contextual or environmental conditions, as well as on user habits or receptive fields. – Is it possible to develop a theory of copying and reproduction on this base? The material of the talk will be drawn from the Parzival-Project, a critical electronic edition of an Arthurian romance, composed by the German poet Wolfram von Eschenbach shortly after 1200 and transmitted in over eighty witnesses.

Norm and Anomaly in the Jewish Life of Jesus (Toledot Yeshu)

The Toledoth Yeshu, the “Generation,” or “Life of Jesus,” have been described as an anti-Gospel, or a parody of the Gospel. This protean tradition, witnessed in more than hundred manuscripts and printed editions, offers a “counter-history” of the life of Jesus and the origins of Christianity. According to this mischievous narrative Jesus was an illegitimate child turned charlatan, and his disciples a bunch of violent and senseless rogues who continued to stir up trouble in Israel even following their leader’s shameful hanging. The Toledoth Yeshu is the story of an anomaly (Jesus and the birth of Christianity). It is also a story about confusion: marital confusion, social confusion, and religious confusion. As an exercise in “historical imagination,” the Toledoth Yeshu offers a narrative of religions compared, and a reflection on social and religious borders, on their instability and fragility, and ultimately on their necessity. The present paper will explore the normative dimension of the Toledoth Yeshu tradition: the way the “disorder of things” the narrative relates also conveys a powerful discourse on social and religious norms. We will also seek to map this tradition in the broader context of medieval Jewish discussions on Jesus (particularly Maimonides) as a “case” in the religious history of mankind, addressing issues of false prophecy, religious deviation, transgression, and heresy.

Kollektive Erinnerung. Topographie und Topik in Walthers ›Palästinalied‹

The French sociologist Maurice Halbwachs (1877–1945) conceived re- membrance as a product of ›collective memory‹ and explained this idea in his book on ›La Topographie légendaire des Évangiles en Terre sainte‹ (1941) showing that the topography of the Holy Land was predominantly an imaginary landscape construed by Christian communities. Following this concept, this article studies the ›Palästinalied‹, a text describing the arrival of a pilgrim in the Holy Land in the time of the crusades, abundantly transmitted under the name of Walther von der Vogelweide. The high degree of textual variance in the diverse manuscripts testifies the acting of ›collective memory‹ in the medieval poetic tradition. Of special interest in this context are the strophic arrangements, the variation of deictic markers, the reworking of melodic models documented in the manuscript transmission and the diatopic opposition existing between the emphasis of ›distant love‹ expressed in Jaufré Rudel’s Occitan song ›Lanqand li jorn son lonc en mai‹ (one of the named models) and the attitude of proximity prevailing in the ›Palästinalied‹.

Achievements and Prospects of Tef Improvement - Proceedings of the Second International Workshop, November 7-9, 2011, Debre Zeit, Ethiopia

These proceedings on ‘Achievements and Prospects of tef Improvement’ is the outcome of the Second International Tef Workshop held at Debre Zeit (Ethiopia), the location which represents the major tef growing areas in the country as well as the oldest and biggest center on tef research. As an indigenous crop, the bulk of tef research is carried out in the country by scientists based at various higher-learning and research institutions. Hence, unlike major crops of the world such as wheat and rice, research on tef benefited little from modern improvement techniques. However, in the recent years, there is an increasing interest by several researchers and funding organizations in developed nations to promote tef research and development through implementation of modern genetic and genomic tools. The recent efforts and progresses made on tef research and development were presented and discussed in detail at the workshop. The tef research and development in Ethiopia has recently shown tremendous improvement. This is witnessed by the decision of the Ethiopian government to award a Gold Medal in November 2012 to our Institute for the discovery and promotion of a very popular Quncho variety. At this juncture, I would like to congratulate all involved in research and development of tef as the achievement was obtained due to concerted efforts of the tef community. The editors of the proceedings did a wonderful job of undertaking the painstaking task of editing all 23 manuscripts presented at the workshop. In addition, the proceedings include a 44-point roadmap for future tef research and development which can be used as a guideline for researchers, development workers and policy makers. I would like to extend my thanks to sponsors of the workshop and the publication of the proceedings.

An analysis of protocols and publications suggested that most discontinuations of clinical trials were not based on preplanned interim analyses or stopping rules.

OBJECTIVES To investigate the frequency of interim analyses, stopping rules, and data safety and monitoring boards (DSMBs) in protocols of randomized controlled trials (RCTs); to examine these features across different reasons for trial discontinuation; and to identify discrepancies in reporting between protocols and publications. STUDY DESIGN AND SETTING We used data from a cohort of RCT protocols approved between 2000 and 2003 by six research ethics committees in Switzerland, Germany, and Canada. RESULTS Of 894 RCT protocols, 289 prespecified interim analyses (32.3%), 153 stopping rules (17.1%), and 257 DSMBs (28.7%). Overall, 249 of 894 RCTs (27.9%) were prematurely discontinued; mostly due to reasons such as poor recruitment, administrative reasons, or unexpected harm. Forty-six of 249 RCTs (18.4%) were discontinued due to early benefit or futility; of those, 37 (80.4%) were stopped outside a formal interim analysis or stopping rule. Of 515 published RCTs, there were discrepancies between protocols and publications for interim analyses (21.1%), stopping rules (14.4%), and DSMBs (19.6%). CONCLUSION Two-thirds of RCT protocols did not consider interim analyses, stopping rules, or DSMBs. Most RCTs discontinued for early benefit or futility were stopped without a prespecified mechanism. When assessing trial manuscripts, journals should require access to the protocol.

A Forgotten Original or an Original Copy? On MS. Douce 387 in the Bodleian Library: Collecting Early Modern Festival Books

Focusing on one manuscript, today in the Bodleian Library, Oxford, this chapter deals with the question how early modern objects became collectable items. The manuscript is categorized as MS. Douce 387 and its name indicates that it came from the collection of Francis Douce (1757–1834), who was keeper of manuscripts in the British Museum from 1799 until 1811. MS. Douce 387 is described in the catalogue of the Douce’ian collection as the “presentation copy with coloured designs by Marten de Vos and others” of the 1595 printed festival book Descriptio publicae gratulationis … in adventu … Ernesti archiducis Austriae. This festival book, printed in Antwerp’s Plantin-Moretus press, was commissioned by the magistrate of the city of Antwerp to commemorate the Joyous Entry of Archduke Ernest of Austria from June 1594; that an “archducal copy” bound in red velvet was commissioned as well and was owned by the Archduke is know as well. However, first research showed that Oxford copy cannot be this “archducal copy” or Marten de Vos’s artist’s copy even though it is the only know version with a handwritten text and hand-drawn illustrations. It rather should be examined as something totally different altogether. The main question remains why someone then commissioned a hand made version of this festival book, something unknown for other books of this genre? Why would someone between 1600 and 1800 sit down and copy texts and prints from a collectable book? Why was there such an on-going interest in early modern festival books? Could this manuscript be the only later made copy of the “archducal volume” or is it rather a forgery made for the European collectors’ market?

Otium et negotium. Reading processes and their cultural backgrounds in early Italian and German humanism

Reading and reading habits have radically changed in the digital age. Readers are no longer physically bound to textual objects and libraries, they deal with texts by copying, altering, and annotating them, and they mix established textual forms with other semiotic systems such as pictograms, icons and images. These circumstances also provoke a renewed research interest in the history of reading. In this talk, I will concentrate on reading processes as to how they were enacted and practised in early Italian and German humanism. I will start with some paradigmatic scenes described in Petrarch’s letters (among others the famous visit of the Mont Ventoux, where Petrarch, after having enjoyed a spectacular panorama, withdraws into the contemplative reading of St-Augustine). The transmission of Petrarch’s writings in humanist circles of Southern Germany (e.g. with the Schedel and Gossembrot families in Nurnberg, Augsburg and Strasburg) will then lead to specific reading practices documented in manuscripts that once belonged to coherent libraries and are nowadays spread all over Europe. In the case of the former tradesman and mayor Sigismund Gossembrot, complex habits of textual annotating and cross-referencing can be observed. The dichotomy of the Latin terms otium (‘rest’ and ‘leisure’) and negotium (‘activity’, but also ‘practice’, ‘negotiation’, ‘circulation of social energy’ in the sense of New Historicism) will be used as an ideal-type outline to describe the occurring processes of reading.

Effectiveness of non-steroidal anti-inflammatory drugs for the treatment of pain in knee and hip osteoarthritis: a network meta-analysis.

BACKGROUND Non-steroidal anti-inflammatory drugs (NSAIDs) are the backbone of osteoarthritis pain management. We aimed to assess the effectiveness of different preparations and doses of NSAIDs on osteoarthritis pain in a network meta-analysis. METHODS For this network meta-analysis, we considered randomised trials comparing any of the following interventions: NSAIDs, paracetamol, or placebo, for the treatment of osteoarthritis pain. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) and the reference lists of relevant articles for trials published between Jan 1, 1980, and Feb 24, 2015, with at least 100 patients per group. The prespecified primary and secondary outcomes were pain and physical function, and were extracted in duplicate for up to seven timepoints after the start of treatment. We used an extension of multivariable Bayesian random effects models for mixed multiple treatment comparisons with a random effect at the level of trials. For the primary analysis, a random walk of first order was used to account for multiple follow-up outcome data within a trial. Preparations that used different total daily dose were considered separately in the analysis. To assess a potential dose-response relation, we used preparation-specific covariates assuming linearity on log relative dose. FINDINGS We identified 8973 manuscripts from our search, of which 74 randomised trials with a total of 58 556 patients were included in this analysis. 23 nodes concerning seven different NSAIDs or paracetamol with specific daily dose of administration or placebo were considered. All preparations, irrespective of dose, improved point estimates of pain symptoms when compared with placebo. For six interventions (diclofenac 150 mg/day, etoricoxib 30 mg/day, 60 mg/day, and 90 mg/day, and rofecoxib 25 mg/day and 50 mg/day), the probability that the difference to placebo is at or below a prespecified minimum clinically important effect for pain reduction (effect size [ES] -0·37) was at least 95%. Among maximally approved daily doses, diclofenac 150 mg/day (ES -0·57, 95% credibility interval [CrI] -0·69 to -0·46) and etoricoxib 60 mg/day (ES -0·58, -0·73 to -0·43) had the highest probability to be the best intervention, both with 100% probability to reach the minimum clinically important difference. Treatment effects increased as drug dose increased, but corresponding tests for a linear dose effect were significant only for celecoxib (p=0·030), diclofenac (p=0·031), and naproxen (p=0·026). We found no evidence that treatment effects varied over the duration of treatment. Model fit was good, and between-trial heterogeneity and inconsistency were low in all analyses. All trials were deemed to have a low risk of bias for blinding of patients. Effect estimates did not change in sensitivity analyses with two additional statistical models and accounting for methodological quality criteria in meta-regression analysis. INTERPRETATION On the basis of the available data, we see no role for single-agent paracetamol for the treatment of patients with osteoarthritis irrespective of dose. We provide sound evidence that diclofenac 150 mg/day is the most effective NSAID available at present, in terms of improving both pain and function. Nevertheless, in view of the safety profile of these drugs, physicians need to consider our results together with all known safety information when selecting the preparation and dose for individual patients.

Vareille M, Kieninger E, Alves MP, et al. Impaired type I and type III interferon induction and rhinovirus control in human cystic fibrosis airway epithelial cells. Thorax 2012;67:517-25. This article has been retracted. In our article recently published in Thorax, we described a novel mechanism explaining the increased susceptibility of patients with cystic fibrosis (CF) to rhinovirus infections, namely defective interferon type I and III production by CF airway epithelial cells. In experiments performed after publication of the article we were unable to consistently replicate our findings of deficient interferon type I and III production by CF airway epithelial cells upon rhinovirus infection. In the light of these results, we carried out detailed investigations of the data reported in the above manuscript and regrettably found evidence of deliberate manipulation of experimental data by the first author Dr M. Vareille. This manipulation was accompanied in some instances by absence of original data files. The manipulation/original data absence involved data presented in most, if not all of the figures, thus we wish to fully retract the paper and apologise to the readers of Thorax and to the scientific community for the inconvenience this has caused. We also checked data published by our group in manuscripts on which Dr Vareille was a co-author and found that data published in these manuscripts had not been manipulated. These two manuscripts, whose data and conclusions we stand by are: Edwards MR, Regamey N, Vareille M, et al.

Enteroaggregative Escherichia coli as a cause of acute diarrhea

Enteroaggregative Escherichia coli (EAEC) are considered an important emerging enteric and food-borne pathogen. The groups importantly affected by EAEC include international travelers, children in the developing world, and patients with HIV infection. EAEC does not commonly cause diarrheal illness in all hosts. ^ The reasons for the observed clinical variation in EAEC infection are multifactorial and are dependant on the pathogen, the inoculum ingested and the host susceptibility. A major obstacle in identifying the mechanism of pathogenesis for EAEC is the heterogeneity in virulence of strains. No EAEC virulence gene is consistently present in all diarrheagenic strains. However, a recent report suggests that a package of plasmid borne and chromosomal virulence factors are under the control of the described transcriptional activator aggR. Although the exact inoculum required for EAEC diarrheal illness is not known, a volunteer study has shown that oral ingestion of 10 10 cfu of virulent EAEC elicited diarrhea. Ongoing studies are being conducted to better define the exact infectious dose. There are also host factors associated with increased susceptibility of persons to diarrheal illness with EAEC. ^ The following three manuscripts: (1) review EAEC as an emerging enteric pathogen; (2) identify EAEC as a cause of acute diarrhea among different subpopulations worldwide; (3) identify virulence characteristics and the molecular epidemiology of EAEC isolates among travelers with diarrheal illness and describe the pathogenesis of EAEC infection. ^

Enlarged tracheoesophageal puncture: A systematic review and retrospective analysis

Background. An enlarged tracheoesophageal puncture (TEP) results in aspiration around the voice prosthesis (VP) and may lead to pneumonia. The aims of this research were: (1) to conduct a systematic review and meta-analysis on enlarged TEP; (2) to analyze preoperative, perioperative, and postoperative risk factors for enlarged TEP; and (3) to evaluate control of leakage around the VP using conservative treatments and adverse events in patients with enlarged TEP.^ Methods. A systematic review was conducted (1978-2008). A summary risk estimate was calculated using a random-effects meta-analysis model. A retrospective cohort study was completed. Patients who underwent total laryngectomy and TEP at The University of Texas M. D. Anderson Cancer Center (MDACC) were included. Multiple logistic regression methods were used to assess risk factors for enlargement. Descriptive and bivariate statistics were calculated to evaluate outcomes and adverse events. Results: Twenty-seven manuscripts were included in the systematic review. The summary risk estimate of enlarged TEP/leakage around the VP was 7.2% (95% CI: 4.8%-9.6%). Temporary VP removal and TEP-site injections were the most commonly reported treatments. Neither prosthetic diameter (p=0.076) nor timing of TEP (p=0.297) significantly increased risk of enlargement per stratified analyses of published outcomes. The cumulative incidence of enlarged TEP was 18.6% (36/194, 95% CI: 13.0%-24.1%) in the MDACC cohort. Enlarged TEP occurred exclusively in irradiated patients. Adjusting for length of follow-up and timing of TEP, advanced nodal disease (ORadjusted: 4.3, 95% CI: 1.0-19.1), stricture (ORadjusted : 3.2, 95% CI: 1.2-8.6), and locoregional recurrence/distant metastasis after laryngectomy (ORadjusted: 6.2, 95% CI: 2.3-16.4) increased risk of enlarged TEP. At last follow-up, conservative methods controlled leakage around the VP in 81% (29/36) of patients. Unresolved leakage was associated with recurrent cancer (p=0.081) and TEP-site irregularity (p=0.003). Relative to those without enlargement, enlarged TEP patients had significantly higher risk of pneumonia (RR: 3.4, 95% CI: 1.9-6.2).^ Conclusions. These data establish that enlarged TEP poses serious health risks, and provide insight into medical and oncologic factors that may contribute to development of this complication. In addition, this research supports the use of conservative treatments to address leakage after enlarged TEP in lieu of complete TEP closure.^
