Le implicazioni metateoriche del confronto tra Habermas e Rawls del 1995 sul concetto di posizione originaria

The article goes through the critical analysis of the rawlsian concept of original position, expressed by Habermas in 1995. Habermasian remarks on the original position aim to undermine the justifiability of such a concept as fundamental to the whole political theory. In fact, it is supposed to substitute the procedures of democratic deliberation with a well thought-out construction belonging uniquely to the theoretician. According to Habermas, substantive outcomes of procedures must be left out from political theory, whose task is to set a standard for the best possible procedures, meaning a democratic framework in which all opinions and beliefs take part to the decision. Rawls approves the critique since from his point of view, no procedure is able to avoid the inclusion of some substantive contents. On such assumption he twists to Habermasian theory the same remarks, observing that it avoids substantive assumptions at political level, embodying them at the epistemic one. As a result, the article raises some issues about the desirability and feasibility of both theories, even considering which interpretation of the role of political philosophy they imply

Precision measurements of Linear Scattering Density using Muon Tomography

We demonstrate that muon tomography can be used to precisely measure the properties of various materials. The materials which have been considered have been extracted from an experimental blast furnace, including carbon (coke) and iron oxides, for which measurements of the linear scattering density relative to the mass density have been performed with an absolute precision of 10%. We report the procedures that are used in order to obtain such precision, and a discussion is presented to address the expected performance of the technique when applied to heavier materials. The results we obtain do not depend on the specific type of material considered and therefore they can be extended to any application.Comment: 16 pages, 4 figure

Assessing the impacts of digital government transformation in the EU

This report presents the results of the conceptual and empirical work conducted as part of the JRC research on “Exploring Digital Government Transformation: understanding public sector innovation in a data-driven society” conducted within the framework of the “European Location Interoperability Solutions for eGovernment (ELISE)" Action of the ISA2 Programme on Interoperability solutions for public administrations, businesses and citizens, coordinated by DIGIT. Building on the systematisation of the state of the art carried out in the previous phase of the research, the report presents an original conceptual framework for assessing the impacts of Digital Government transformation in the EU and discusses the results of case studies carried out using an experimental or quasi-experimental approach to test and validate it, carried out in different policy areas in various EU countries. The report concludes outlining the final proposal of DigiGov F 2.0, which defines the dimensions and elements of analysis for assessing the effects that can be generated by digital innovation in the public sector and the impacts they have at social, economic and political levels in different policy-cycle phases and governance contexts.JRC.B.6-Digital Econom

Exploring Digital Government transformation in the EU

This report presents the findings of the analysis of the state of the art conducted as part of the JRC research on “Exploring Digital Government Transformation in the EU: understanding public sector innovation in a data-driven society” (DIGIGOV), within the framework of the “European Location Interoperability Solutions for eGovernment (ELISE)" Action of the ISA2 Programme on Interoperability solutions for public administrations, businesses and citizens, coordinated by DIGIT. The results of the review of literature, based on almost 500 academic and grey literature sources, as well as the analysis of digital government policies in the EU Member States provide a synthetic overview of the main themes and topics of the digital government discourse. The report depicts the variety of existing conceptualisations and definitions of the digital government phenomenon, measured and expected effects of the application of more disruptive innovations and emerging technologies in government, as well as key drivers and barriers for transforming the public sector. Overall, the literature review shows that many sources appear overly optimistic with regard to the impact of digital government transformation, although the majority of them are based on normative views or expectations, rather than empirically tested insights. The authors therefore caution that digital government transformation should be researched empirically and with a due differentiation between evidence and hope. In this respect, the report paves the way to in-depth analysis of the effects that can be generated by digital innovation in public sector organisations. A digital transformation that implies the redesign of the tools and methods used in the machinery of government will require in fact a significant change in the institutional frameworks that regulate and help coordinate the governance systems in which such changing processes are implemented.JRC.B.6-Digital Econom

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

Myoclonus and Cerebellar Ataxia Associated with SARS-CoV-2 Infection: Case Report and Review of the Literature

The current SARS-CoV-2/COVID-19 pandemic has led to a global health crisis. The clinical spectrum of SARS-CoV-2 infection ranges from asymptomatic infection to critical illness affecting almost every organ including the central and peripheral nervous systems. Myoclonus, a less expected and relatively unusual neurological complication, together with ataxia, has lately been associated with SARS-CoV-2 infection. We describe the case of a 67-year-old male patient, admitted to our hospital for interstitial bilateral pneumonia due to SARS-CoV-2 infection, who progressively developed general myoclonus and later cerebellar ataxia and gait disturbance. Given the timeline from COVID-19 systemic symptoms to neurological manifestations and the normal results of extensive and non-conclusive diagnostic work-up (blood test, lumbar puncture, EEG, cerebral MRI), a para-infectious encephalopathy related to SARS-CoV-2 was contemplated and a high dose of methylprednisolone was started with prompt symptom improvement. Further investigation and neuroepidemiological studies are needed to help define the mechanism of neuroinvasion and the entire spectrum of neurological manifestations of SARS-CoV-2 infection, even in mildly affected patients, in terms of prevention, treatment and possible neurological sequelae

Exploring the capability of muon scattering tomography for imaging the components in the blast furnace

Knowing the distribution of the materials in the blast furnace (BF) is believed to be of great interest for BF operation and process optimization. In this paper calibration samples (ferrous pellets and coke) and samples from LKAB’s experimental blast furnace (probe samples, excavation samples and core-drilling samples) were measured by the muon scattering tomography detector to explore the capability of using the muon scattering tomography to image the components in the blast furnace. The experimental results show that it is possible to use this technique to discriminate the ferrous pellets from the coke and it is also shown that the measured linear scattering densities (LSD) linearly correlate with the bulk densities of the measured materials. By applying the Stovall’s model a correlation among the LSD values, the bulk densities and the components of the materials in the probe samples and excavation samples was established. The theoretical analysis indicates that it is potential to use the present muon scattering tomography technique to image the components in various zones of the blast furnace
