The paper reports on preliminary results of an ongoing research aiming at development of an automatic procedure for recognition of discourse-compositional structure of scientific and technical texts, which is required in many NLP applications. The procedure exploits as discourse markers various domain-independent words and expressions that are specific for scientific and technical texts and organize scientific discourse. The paper discusses features of scientific discourse and common scientific lexicon comprising such words and expressions. Methodological issues of development of a computer dictionary for common scientific lexicon are concerned; basic principles of its organization are described as well. Main steps of the discourse-analyzing procedure based on the dictionary and surface syntactical analysis are pointed out.

Previous studies have demonstrated that a region in the left ventral occipito-temporal (LvOT) cortex is highly selective to the visual forms of written words and objects relative to closely matched visual stimuli. Here, we investigated why LvOT activation is not higher for reading than picture naming even though written words and pictures of objects have grossly different visual forms. To compare neuronal responses for words and pictures within the same LvOT area, we used functional magnetic resonance imaging adaptation and instructed participants to name target stimuli that followed briefly presented masked primes that were either presented in the same stimulus type as the target (word-word, picture-picture) or a different stimulus type (picture-word, word-picture). We found that activation throughout posterior and anterior parts of LvOT was reduced when the prime had the same name/response as the target irrespective of whether the prime-target relationship was within or between stimulus type. As posterior LvOT is a visual form processing area, and there was no visual form similarity between different stimulus types, we suggest that our results indicate automatic top-down influences from pictures to words and words to pictures. This novel perspective motivates further investigation of the functional properties of this intriguing region.

Provenance plays a major role when understanding and reusing the methods applied in a scientic experiment, as it provides a record of inputs, the processes carried out and the use and generation of intermediate and nal results. In the specic case of in-silico scientic experiments, a large variety of scientic workflow systems (e.g., Wings, Taverna, Galaxy, Vistrails) have been created to support scientists. All of these systems produce some sort of provenance about the executions of the workflows that encode scientic experiments. However, provenance is normally recorded at a very low level of detail, which complicates the understanding of what happened during execution. In this paper we propose an approach to automatically obtain abstractions from low-level provenance data by finding common workflow fragments on workflow execution provenance and relating them to templates. We have tested our approach with a dataset of workflows published by the Wings workflow system. Our results show that by using these kinds of abstractions we can highlight the most common abstract methods used in the executions of a repository, relating different runs and workflow templates with each other.

It is usually assumed that Heraclitus is, exclusively, the philosopher of flux, diversity and opposition while Parmenides puts the case for unity and changelessness. However, there is a significant common understanding of things (though in differing contexts), not simply an accidental similarity of understanding. Both philosophers, critically, distinguish two realms: on the one hand, there is the one, common realm, identical for all, which is grasped by the ‘logos that is common’(Heraclitus) or the steady nous (Parmenides) that follows a right method in order to interpret the real. On the other hand, the realm of multiplicity seen and heard by the senses, when interpreted by ‘barbarian souls’, is not understood in its common unity. Analogously, when grasped by the wandering weak nous it does not comprehend the real’s basic unity. In this paper I attempt to defend the thesis that both thinkers claim that the common logos (to put it in Heraclitean terms) or the steady intellect (to say it with Parmenides) grasp and affirm the unity of the real.

This article presents reading strategies that seek to contribute to better understand the words and images used in digital advertising discourse of cosmetic antisignals intended in particular to female audiences. For this analysis, we start from the assumption that, if such products are sold, the language of advertising messages carefully prepares to persuade the female audience to a possible need to purchase. The development of reading strategies is supported by the Polyphonic Theory of the Utterance of Oswald Ducrot, so that these serve as input for similar analysis, covering other text types. It starts from the assumption that there is a common given in these ads: the advertised products are invested in a magical power, which suggests that can minimize or even eliminate the marks that the time printed on the faces of those who use the products.

Words and Silences is the official on-line journal of the International Oral History Association. It is an internationally peer reviewed, high quality forum for oral historians from a wide range of disciplines and a means for the professional community to share projects and current trends of oral history from around the world. We are extremely pleased to release the first online issue of Word &Silences. This e-journal is the result of long standing discussion and debate about the best way to publish a quality bilingual oral history journal (including a blind peer reviewed section) as a viable solution to mounting difficulties associated with publishing in print. We have discovered that an online version is also not without its challenges and requires tremendous labor intensive dedication. We strongly encourage members to assist us with small review process tasks in the future, so that we can ensure the sustainability of an annual W&S publication for our members and beyond.

We consider how data from scientific research should be used for decision making in health services. Whether a hand hygiene intervention to reduce risk of nosocomial infection should be widely adopted is the case study. Improving hand hygiene has been described as the most important measure to prevent nosocomial infection. 1 Transmission of microorganisms is reduced, and fewer infections arise, which leads to a reduction in mortality2 and cost savings.3 Implementing a hand hygiene program is itself costly, so the extra investment should be tested for cost-effectiveness.4,5 The first part of our commentary is about cost-effectiveness models and how they inform decision making for health services. The second part is about how data on the effectiveness of hand hygiene programs arising from scientific studies are used, and 2 points are made: the threshold for statistical inference of .05 used to judge effectiveness studies is not important for decision making,6,7 and potentially valuable evidence about effectiveness might be excluded by decision makers because it is deemed low quality.8 The ideas put forward will help researchers and health services decision makers to appraise scientific evidence in a more powerful way.
