Comparitive assessment of the vulnerability and resilience of 10 deltas, synthesis report
The proposed framework for delta assessment and especially the scorecards are intended to enhance awareness raising, discussion and prioritization on most relevant delta issues, in each delta but also in comparison with other deltas. This should lead to more efficient and effective (multi-sectoral) policy formulation, management design and implementation, in concrete Delta plans, pilot-projects and (research) programmes. The target groups are all stakeholders who are involved in delta management at different levels and with different interests (government, private companies, NGOs, public), and who wish to contribute to the resilience of their own delta and other deltas worldwide

Enhancing target language output through synchronous online learner-learner interaction: the impact of audio-, video-, and text-chat interaction on learner output and affect
In this study, we compared the impact of audio-, video-, and text-chat interaction on target language use during online learner-learner interaction and on learner affect amongst adolescent learners of German as a foreign language. Repeated measures and ANOVA analyses revealed a high percentage of target language output in all conditions for all four tasks, especially in text chat. Audio-chatters produced the most output and used the most meaning negotiation, compensation strategies, self-repair and other-repair strategies. Learners in all conditions gained in enjoyment, willingness to communicate and self-efficacy. Anxiety reduced for text-chatters. Task effects partly determined the quantity of L2 output, while condition effects determined meaning-oriented and form-focused processing
Focus on language versus content in the pre-task: Effects of guided peer-video model observations on task performance
The present experimental study examined whether a different focus during a pre-task planning observation task affects learners’ subsequent oral task performance. Forty-eight ninth-grade students learning German as a foreign language were randomly assigned to two different planning conditions: video observations with a focus on language (FonL) and video observations with a focus on content (FonC). With a communicative oral task we measured the effects on oral task performance, in terms of attempted (accurate) use of the target structure and complexity, in terms of number of words, subordination and coordination. In addition we investigated whether there was a trade-off between attempted (accurate) use of the target structure and complexity. Results showed that the focus of the observations at the pre-task stage did indeed lead to different outcomes: students in the language condition used the grammatical target structure more often and more accurately, whereas students of the content condition generated more coordinate and subordinate clauses. Trade-offs were found between attempted (accurate) use of the target structure and the use of subordinate clauses. These findings imply that, depending on the purposes of the lesson, the observation of peer-model videos with different planning foci can be effectively used to promote (accurate) use of targeted grammatical structures and improve complexity during subsequent task performance
AGMIAL: implementing an annotation strategy for prokaryote genomes as a distributed system
We have implemented a genome annotation system for prokaryotes called AGMIAL. Our approach embodies a number of key principles. First, expert manual annotators are seen as a critical component of the overall system; user interfaces were cyclically refined to satisfy their needs. Second, the overall process should be orchestrated in terms of a global annotation strategy; this facilitates coordination between a team of annotators and automatic data analysis. Third, the annotation strategy should allow progressive and incremental annotation from a time when only a few draft contigs are available, to when a final finished assembly is produced. The overall architecture employed is modular and extensible, being based on the W3 standard Web services framework. Specialized modules interact with two independent core modules that are used to annotate, respectively, genomic and protein sequences. AGMIAL is currently being used by several INRA laboratories to analyze genomes of bacteria relevant to the food-processing industry, and is distributed under an open source license
