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.

Der Körper als Gefäß. Eine Studie zur visuellen Anthropologie des Alten Orients

The perception of the human body as container is widespread in cognitive linguistics, psychology and anthropology and is estimated to be universal. But what can we say about the specific context of the Hebrew Bible as well as Ancient-Near-Eastern texts and material culture, and more especially about anthropomorphic vessels in the Levant? Biblical, Egyptian and Mesopotamian texts compare the human body with pottery in order to emphasize its status of having been created (Geschöpflichkeit) on the one hand, and its fragility (Zerbrechlichkeit) on the other. Not in every case does the metaphor refer to an individual. Very often, however, it is used with relation to groups of people (nations) and requires particular caution when it comes to drawing a conclusion about the embodiment. The archaeological-iconographic record demonstrates that the human body, especially the female body, was imagined as a container. The fact that vessels in the shape of female bodies are the majority can partly be explained with the association between container and pregnancy. This essay aims at stimulating the discussion about embodiment in the Ancient Near East, concepts of emotion the body as a container in the Hebrew Bible, and its relation to the material culture.

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.
