Provenance: The Bridge Between Experiments and Data

Current scientific applications are often structured as workflows and rely on workflow systems to compile abstract experiment designs into enactable workflows that utilise the best available resources. The automation of this step and of the workflow enactment, hides the details of how results have been produced. Knowing how compilation and enactment occurred allows results to be reconnected with the experiment design. We investigate how provenance helps scientists to connect their results with the actual execution that took place, their original experiment and its inputs and parameters.

The posterior parietal cortex: a bridge between vision and action

The present work takes into account three posterior parietal areas, V6, V6A, and PEc, all operating on different subsets of signals (visual, somatic, motor). The work focuses on the study of their functional properties, to better understand their respective contribution in the neuronal circuits that make possible the interactions between subject and external environment. In the caudalmost pole of parietal lobe there is area V6. Functional data suggest that this area is related to the encoding of both objects motion and ego-motion. However, the sensitivity of V6 neurons to optic flow stimulations has been tested only in human fMRI experiments. Here we addressed this issue by applying on monkey the same experimental protocol used in human studies. The visual stimulation obtained with the Flow Fields stimulus was the most effective and powerful to activate area V6 in monkey, further strengthening this homology between the two primates. The neighboring areas, V6A and PEc, show different cytoarchitecture and connectivity profiles, but are both involved in the control of reaches. We studied the sensory responses present in these areas, and directly compared these.. We also studied the motor related discharges of PEc neurons during reaching movements in 3D space comparing also the direction and depth tuning of PEc cells with those of V6A. The results show that area PEc and V6A share several functional properties. Area PEc, unlike V6A, contains a richer and more complex somatosensory input, and a poorer, although complex visual one. Differences emerged also comparing the motor-related properties for reaches in depth: the incidence of depth modulations in PEc and the temporal pattern of modulation for depth and direction allow to delineate a trend among the two parietal visuomotor areas.

Immunoglobulin A: a bridge between innate and adaptive immunity

The review summarizes the recent progress that has been made in understanding the function of immunoglobulin A (IgA) in promoting a healthy mutualism with the commensal microbiota and protecting against pathogens. Although IgA is by far the most abundant antibody produced by mammals, direct experimental evidence for its function is still lacking.

A public-professional web-bridge for vaccines and vaccination: User concerns about vaccine safety

Vacunas.org (http://www.vacunas.org), a website founded by the Spanish Association of Vaccinology offers a personalized service called Ask the Expert, which answers any questions posed by the public or health professionals about vaccines and vaccination. The aim of this study was to analyze the factors associated with questions on vaccination safety and determine the characteristics of questioners and the type of question asked during the period 2008–2010. A total of 1341 questions were finally included in the analysis. Of those, 30% were related to vaccine safety. Questions about pregnant women had 5.01 higher odds of asking about safety (95% CI 2.82–8.93) than people not belonging to any risk group. Older questioners (>50 years) were less likely to ask about vaccine safety compared to younger questioners (OR: 0.44, 95% CI 0.25–0.76). Questions made after vaccination or related to influenza (including H1N1) or travel vaccines were also associated with a higher likelihood of asking about vaccine safety. These results identify risk groups (pregnant women), population groups (older people) and some vaccines (travel and influenza vaccines, including H1N1) where greater efforts to provide improved, more-tailored vaccine information in general and on the Internet are required.

Disclosure of Leniency Materials: A Bridge between Public and Private Enforcement of Antitrust Law. Research Paper in Law 08/2013, December

The disclosure of leniency materials held by competition authorities has recently been under the spot. On the one hand, these documents could greatly help cartel victims to prove the damage and the causation link when filing damage actions against cartelists. On the other hand, future cartelists could be deterred from applying for leniency since damage actions could be brought as a result of the information submitted by themselves. Neither the current legislation nor the case law have attained yet to sufficiently clarify how to deal with this clash of interests. Our approach obviously attempts to strike a balance between both interests. But not only that. We see the current debate as a great opportunity to boost the private enforcement of antitrust law through the positive spillovers of leniency programmes. We hence propose to build a bridge between the public and the private enforcement by enabling a partial disclosure of the documents.
