Open Government Data: A Focus on Key Economic and Organizational Drivers

Grounding the analysis on multidisciplinary literature on the topic, the existing EU legislation and relevant examples, this working paper aims at highlighting some key economic and organizational aspects of the "Open Government Data" paradigm and its drivers and implications within and outside Public Administrations. The discussion intends to adopt an "Internet Science" perspective, taking into account as enabling factors the digital environment itself, as well as specific models and tools. More "traditional" and mature markets grounded on Public Sector Information are also considered, in order to indirectly detect the main differences with respect to the aforementioned paradig

The phosphorous necrosis of the jaws and what can we learn from the past: a comparison of "phossy" and "bisphossy" jaw

INTRODUCTION: The osteopathology of the jaws associated with bone resorption inhibitors is a current topic that engages a variety of clinical specialists. This has increased after the approval of denosumab for treatment of osteoporosis and skeletal-related events in patients with solid malignancy. Early after the first publications, there is a possible connection between phosphorous necrosis of the jaws, a dreadful industrial disease mentioned, and bisphosphonate-induced pathology. The nineteenth century was the prime time for phosphorus necrosis of match factory workers. RESULTS: This occurrence provides an interesting insight into the medical and surgical profession in the nineteenth century. There are striking parallels and repetition of current and old ideas in the approach to this "new disease." There are similar examples in case descriptions when compared with today's patients of bisphosphonate-related osteonecrosis of the jaws (BRONJ). DISCUSSION: Phosphorus necrosis was first described in Austria. Soon after this, surgeons in German-speaking countries including well-known clinicians Wegner (1872) and von Schulthess-Rechberg (1879) pioneered the analysis, preventative measures, and treatment of this disease. The tendency at this time was to approach BRONJ as a "special kind of osteomyelitis" in pretreated and metabolically different bone. Not only the treatment strategy to wait until sequestrum formation with subsequent removal and preventative measures but also the idea of focusing on the periosteum as the triggering anatomical structure may have been adopted from specialists in the nineteenth century. Therefore, phosphorous necrosis of the jaw is an excellent example of "learning from the past.

Limits on the production of scalar leptoquarks from Z (0) decays at LEP

A search has been made for pairs and for single production of scalar leptoquarks of the first and second generations using a data sample of 392000 Z0 decays from the DELPHI detector at LEP 1. No signal was found and limits on the leptoquark mass, production cross section and branching ratio were set. A mass limit at 95% confidence level of 45.5 GeV/c2 was obtained for leptoquark pair production. The search for the production of a single leptoquark probed the mass region above this limit and its results exclude first and second generation leptoquarks D0 with masses below 65 GeV/c2 and 73 GeV/c2 respectively, at 95% confidence level, assuming that the D0lq Yukawa coupling alpha(lambda) is equal to the electromagnetic one. An upper limit is also given on the coupling alpha(lambda) as a function of the leptoquark mass m(D0)

On the dominant role of the baryon variables in the description of high-multiplicity interactions at high energy

It is shown that in the reactions: π++p→p+5π and π++p→p+6π at 8 GeV/c the secondary protons determine the general features of the pion distributions

New results of paleomagnetic studies of red-colored Silurian deposits

New results of paleomagnetic studies of red-colored rocks of the Late Silurian of southwestern Ukraine (Podolian area, the Dniester river basin) have been presented. Sedimentary unit of red-colored deposits as a part of upperconovsk subsuite of Malinovets series are represented by dolomites comparable with Ludford stage of the International geological scale, and was studied in two sections. The distinguished medium-temperature component of magnetization (O = 53,4 °S, A = 5,9 °E) corresponds to the direction of the Permian poles TCMP for the Baltic area that indicates magnetization reversal of rocks. High temperature (characteristic) component of magnetization distinguished on lots of samples of the Konovsk suite corresponds to the Silurian fragment of TCMP for the Baltic and is determined by the presence of terrigenous hematite (ti-tanomagnetite) grains and is, according to our interpretation, the primary magnetization. Its corresponding paleomagnetic pole (O = 19,9 °S, A = 339,8 °E) is in good agreement with the Silurian fragment of TCMP. The results are in good accordance with the previous measurements for grey-colored sedimentary rocks of the Silurian from Podolia
