Trusted and Relevant Medical Knowledge: The Promise of Information Retrieval
Creators: name: Silfen, Eric
Publisher: name: Digital Repository at the University of Maryland
Year: 2006

description: As the world of medicine becomes increasingly digitized, the Web has become a de facto resource for physicians to quickly glean pertinent clinical information to carry out diagnostic and therapeutic decisions.At present, physicians face the dual challenge of judging the relevance of the information and trusting its Web source.This paper proposes a trust-relevance framework for conceptualizing computer-accessed medical information resources, a set of criteria for evaluating these information resources, and descriptions of a sample of available online resources. It also presents a usable framework for evaluating information retrieval innovations and explains the different capabilities of representative information retrieval tools and applications. By demystifying the concepts associated with information resources, search engines, and retrieval tools, and presenting a reasonable view of current opportunities as well as future possibilities, the authors hope to provide guidance so physicians can more rapidly adopt innovative computer-assisted search tools for acquiring information that facilitate patient care decision-making.
Two new diagnostics of dark energy

description: We introduce two new diagnostics of dark energy (DE). The first, Om, is a combination of the Hubble parameter and the cosmological redshift and provides a "null test" of dark energy being a cosmological constant. Namely, if the value of Om(z) is the same at different redshifts, then DE is exactly cosmological constant. The slope of Om(z) can differentiate between different models of dark energy even if the value of the matter density is not accurately known. For DE with an unevolving equation of state, a positive slope of Om(z) is suggestive of Phantom (w < -1) while a negative slope indicates Quintessence (w > -1). The second diagnostic, "acceleration probe"(q-probe), is the mean value of the deceleration parameter over a small redshift range. It can be used to determine the cosmological redshift at which the universe began to accelerate, again without reference to the current value of the matter density. We apply the "Om" and "q-probe" diagnostics to the Union data set of type Ia supernovae combined with recent data from the cosmic microwave background (WMAP5) and baryon acoustic oscillations.

description: The EU customs management system is based on uniform legislation that is implemented on a decentralised basis by the Member States. In theory, the Customs Union should operate as if it were one single administration. In practice, the non-harmonised and uncoordinated application of the common customs legislation disrupts the proper functioning of the Customs Union. The objective of this Insight is to analyse and assess the current model of customs administration in the European Union, focusing on the shortcomings of the system and its consequences in the form of customs fraud. The Insight uses as a case study the undervaluation fraud case concerning textile and shoes imported from China via the United Kingdom between 2011 and 2017, still pending before the Court of Justice of the European Union.

description: We report the realization of a solid-state triggered single-photon source with narrow emission in the near infrared at room temperature. It is based on the photoluminescence of a single nickel-nitrogen NE8 colour centre in a chemical vapour deposited diamond nanocrystal. Stable single-photon emission has been observed in the photoluminescence under both continuous-wave and pulsed excitations. The realization of this source represents a step forward in the application of diamond-based single-photon sources to Quantum Key Distribution (QKD) under practical operating conditions.

Diffuse TeV Emission at the Galactic Centre

description: The High-Energy Stereoscopic System (HESS) has detected intense diffuse TeV emission correlated with the distribution of molecular gas along the galactic ridge at the centre of our Galaxy. Earlier HESS observations of this region had already revealed the presence of several point sources at these energies, one of them (HESS J1745-290) coincident with the supermassive black hole Sagittarius A*. It is still not entirely clear what the origin of the TeV emission is, nor even whether it is due to hadronic or leptonic interactions. It is reasonable to suppose, however, that at least for the diffuse emission, the tight correlation of the intensity distribution with the molecular gas indicates a pionic-decay process involving relativistic protons. In this paper, we explore the possible source(s) of energetic hadrons at the galactic centre, and their propagation through a turbulent medium. We conclude that though Sagittarius A* itself may be the source of cosmic rays producing the emission in HESS J1745-290, it cannot be responsible for the diffuse emission farther out. A distribution of point sources, such as pulsar wind nebulae dispersed along the galactic plane, similarly do not produce a TeV emission profile consistent with the HESS map. We conclude that only a relativistic proton distribution accelerated throughout the inter-cloud medium can account for the TeV emission profile measured with HESS.

description: The extended Hubbard Hamiltonian is a widely accepted model for uncovering the effects of strong correlations on the phase diagram of low-dimensional systems, and a variety of theoretical techniques have been applied to it. In this paper the world-line quantum Monte Carlo method is used to study spin, charge, and bond order correlations of the one-dimensional extended Hubbard model in the presence of coupling to the lattice. A static alternating lattice distortion (the ionic Hubbard model) leads to enhanced charge density wave correlations at the expense of antiferromagnetic order. When the lattice degrees of freedom are dynamic (the Hubbard-Holstein model), we show that a similar effect occurs even though the charge asymmetry must arise spontaneously. Although the evolution of the total energy with lattice coupling is smooth, the individual components exhibit sharp crossovers at the phase boundaries. Finally, we observe a tendency for bond order in the region between the charge and spin density wave phases.

description: We have detected over 400 HI clouds in the lower halo of the Galaxy within the pilot region of the Galactic All-Sky Survey (GASS), a region of the fourth quadrant that spans 18 degrees in longitude, 40 degrees in latitude and is centered on the Galactic equator. These clouds have a median peak brightness temperature of 0.6 K, a median velocity width of 12.8 km/s, and angular sizes <1 degree. The motion of these clouds is dominated by Galactic rotation with a random cloud-to-cloud velocity dispersion of 18 km/s. A sample of clouds likely to be near tangent points was analyzed in detail. These clouds have radii on the order of 30 pc and a median HI mass of 630 Msun. The population has a vertical scale height of 400 pc and is concentrated in Galactocentric radius, peaking at R=3.8 kpc. This confined structure suggests that the clouds are linked to spiral features, while morphological evidence that many clouds are aligned with loops and filaments is suggestive of a relationship with star formation. The clouds might result from supernovae and stellar winds in the form of fragmenting shells and gas that has been pushed into the halo rather than from a galactic fountain.

description: Deep Neural Networks (DNNs) have emerged as the core enabler of many major applications on mobile devices. To achieve high accuracy, DNN models have become increasingly deep with hundreds or even thousands of operator layers, leading to high memory and computational requirements for inference. Operator fusion (or kernel/layer fusion) is key optimization in many state-of-the-art DNN execution frameworks, such as TensorFlow, TVM, and MNN. However, these frameworks usually adopt fusion approaches based on certain patterns that are too restrictive to cover the diversity of operators and layer connections. Polyhedral-based loop fusion techniques, on the other hand, work on a low-level view of the computation without operator-level information, and can also miss potential fusion opportunities. To address this challenge, this paper proposes a novel and extensive loop fusion framework called DNNFusion. The basic idea of this work is to work at an operator view of DNNs, but expand fusion opportunities by developing a classification of both individual operators and their combinations. In addition, DNNFusion includes 1) a novel mathematical-property-based graph rewriting framework to reduce evaluation costs and facilitate subsequent operator fusion, 2) an integrated fusion plan generation that leverages the high-level analysis and accurate light-weight profiling, and 3) additional optimizations during fusion code generation. DNNFusion is extensively evaluated on 15 DNN models with varied types of tasks, model sizes, and layer counts. The evaluation results demonstrate that DNNFusion finds up to 8.8x higher fusion opportunities, outperforms four state-of-the-art DNN execution frameworks with 9.3x speedup. The memory requirement reduction and speedups can enable the execution of many of the target models on mobile devices and even make them part of a real-time application.

description: Il fiume come oggetto geografico di indagine ha riscosso da sempre particolare attenzione negli studi geografici, sia negli aspetti socio-culturali sia fisico-idraulici, essendo un elemento di transizione fluido, che si svela e viene percepito in tutta la sua importanza soprattutto nelle estreme manifestazioni di assenza (siccità) e presenza (inondazioni). Se si escludono le aree desertiche, qualsiasi pertinenza geografica del pianeta si identifica grazie all’orditura di un bacino fluviale. Indipendentemente dai più o meno cospicui deflussi superficiali ciò corrisponde a un ciclo idrosociale da cui derivano degli assetti sociali e fisiografici peculiari. La presenza dell’acqua, il suo riordino, il controllo dei deflussi, sono tra gli aspetti più significativi della trasformazione operata dagli esseri umani sulla base naturale. Quando prendiamo in considerazione lo studio degli ambiti fluviali ci troviamo necessariamente di fronte a una pluralità di prospettive di indagine che rispecchiano l’ontologia stessa dell’oggetto: inafferrabile e tangibile, molteplice e unico, fonte di vita e di morte, lineare e intrecciato, naturale e culturale, impetuoso e calmo.

Type: Nixonia pretiosa Masner, by monotypy and original designation. For subsequent taxonomic literature see Johnson (1992) or The Genera of Platygastroidea of the World (http://purl.oclc.org/ NET/ hymenoptera /platygastroidea). Diagnosis. Nixonia is superficially similar to Scelio Latreille, and to the larger, more elongate species of Macroteleia Westwood and Triteleia Kieffer. Nixonia is distinguished by the 14segmented, nonclavate antennae; the strong medial propodeal tooth; and the presence of two tibial spurs on both the mid-and hind tibiae. Distribution. Nixonia species richness is centered in southern Africa, but distribution extends north to Egypt, Kenya, Somalia, Rwanda, and the Democratic Republic of Congo (former Zaire). A single species, N. krombeini, is found in Sri Lanka, northern India, and southeast Asia (Th ailand, Laos, and Vietnam). See http://hol.osu.edu/ map-large.html?id=523 for distribution map. Biology. Only one species has been reared: Nixonia watshami a parasitoid of the eggs of A. discoidalis (Walker, 1869) (Orthoptera: Tettigoniidae, Hetrodinae). The subfamily Hetrodinae is endemic to Africa and adjacent areas of the Arabian Peninsula (Otte et al. 2009) and all 14 genera are likely to play hosts for Nixonia species. Th e host, however, of at least N. krombeini which occurs outside the range of Heterodinae in tropical Asia must be some other large orthopteran (Johnson and Masner 2006).

description: In Bank Refah (judgment of 6 October 2020, case C-134/19 P) the Court of Justice provides important clarifications on the type of judicial remedies available in relation to CFSP decisions establishing restrictive measures. As in Rosneft, the Court seems to extend its jurisdiction beyond the so-called "claw-back" provision of Art. 275, para. 2, TFEU. However, in Bank Refah the Court of Justice does not build upon the logic developed in Rosneft, but it takes a different approach. This Insight focuses on the line of argument used by the Court and seeks to identify its implication for the post-Lisbon framework of relations between CFSP and other EU policies.
Capturing a Polycentric World: Quantitative Evidence from Contested Sociotechnical Imaginaries around China’s Social Credit System
Creators: name: Zhou, Shibing
Publisher: name: University of Chicago
Year: 2021

description: Building on the work of Wimmer and others regarding the limitations of conceiving of the world as a unified sphere for global diffusion, this paper offers a hypothesis on a polycentric world for globalization studies. Through the lens of sociotechnical imaginaries concerning futures attainable through advances in science and technology, this paper presents an empirical inquiry into the polycentric world thesis by examining the global controversy around China’s social credit system. I analyze policy documents, journal articles and news on the web with a computational approach through techniques of text mining and bilingual word embedding. The results reveal disparate fields of discussion concerning the social credit system’s planning, effectiveness and influences on civic life in national and transnational domains. The findings provide evidence for the existence of multiple centers in global social space, in terms of contested sociotechnical imaginaries. Thus, they lend support to a revamped research program that transcends the postwar era of globalization. Contributing to the literature on global diffusion, this paper presents a case for attending to the constitution of global social space, and the multiple sources of influences within.

description: A random access memory (RAM) uses n bits to randomly address N=2^n distinct memory cells. A quantum random access memory (qRAM) uses n qubits to address any quantum superposition of N memory cells. We present an architecture that exponentially reduces the requirements for a memory call: O(log N) switches need be thrown instead of the N used in conventional (classical or quantum) RAM designs. This yields a more robust qRAM algorithm, as it in general requires entanglement among exponentially less gates, and leads to an exponential decrease in the power needed for addressing. A quantum optical implementation is presented.

Dimensionamento di un dispositivo a getto sintetico per scambio termico

description: L’obiettivo principale di questa tesi è stato quello di definire un criterio di progettazione
dell’attuatore di un getto sintetico per scambio termico e valutarne le prestazioni.
E’ apparso opportuno aprire la tesi con una breve introduzione al fenomeno della turbolenza,
con riferimento ai modelli matematici per la chiusura delle equazioni di Reynolds, che rappresentano
classicamente le equazioni mediate di Navier-Stokes e introducono la presenza di un termine aggiuntivo di sforzo,
il tensore degli stress di Reynolds, caratteristica intrinseca  del regime turbolento.
La presente tesi ha come scopo il progetto di un attuatore di getto sintetico.
Definite le caratteristiche di progetto (ad esempio, diametro di uscita dell’ugello e numero di Reynolds),
il dimensionamento del sistema è effettuato sulla base di un criterio pratico di formazione del getto.
Le prestazioni del dispositivo sono, quindi, valutate, mediante simulazioni numeriche effettuate con un codice
commerciale allo scopo di determinare le distribuzioni spaziali del coefficiente di scambio termico
(numero di Nusselt) tra il getto e le  superfici calde su cui il getto incide, al variare di alcuni parametri
tra cui la distanza ugello-lastra.
Identificazione di proteine con attività di legame agli mRNA degli antigeni MHC di classe II

description: Major Histocompatibility Complex class II mRNAs encode heterodimeric proteins involved in the
presentation of exogenous antigens during immune response. Their 3'UTRs bind a protein complex
in which we identified two factors: EBP1, an Erb3 receptor-binding protein, and DRBP76, a
double-stranded RNA-binding Nuclear Protein, also known as Nuclear Factor 90. Both are well
characterized regulatory factors of several mRNA molecules processing. Using either EBP1 or
DRBP76/NF90 specific knockdown experiments, we established that the two proteins play a role in
regulating the expression of HLA-DRA, HLA-DRB1 and HLA-DQA1 mRNAs levels. Our study
represents the first indication of the existence of a functional unit that includes different transcripts
involved in the adaptive immune response. We propose that the concept of “RNA operon” may be
suitable for our system in which MHCII mRNAs are modulated via interaction of their 3’UTR with
same proteins.

description: Recently it was shown that the eigenfunctions for the the asymmetric exclusion problem and several of its generalizations as well as a huge family of quantum chains, like the anisotropic Heisenberg model, Fateev- Zamolodchikov model, Izergin-Korepin model, Sutherland model, t-J model, Hubbard model, etc, can be expressed by a matrix product ansatz. Differently from the coordinate Bethe ansatz, where the eigenvalues and eigenvectors are plane wave combinations, in this ansatz the components of the eigenfunctions are obtained through the algebraic properties of properly defined matrices. In this work, we introduce a formulation of a matrix product ansatz for the six-vertex model with periodic boundary condition, which is the paradigmatic example of integrability in two dimensions. Remarkably, our studies of the six-vertex model are in agreement with the conjecture that all models exactly solved by the Bethe ansatz can also be solved by an appropriated matrix product ansatz.

description: A family of titanium oxypnictide materials BaTi2Pn2O (Pn = pnictogen) becomes superconducting when a charge and/or spin density wave is suppressed. With hole doping, isovalent doping and pressure, a whole range of tuning parameters is available. We investigate how charge doping controls the superconducting transition temperature Tc. To this end, we use experimental crystal structure data to determine the electronic structure and Fermi surface evolution along the doping path. We show that a naive approach to calculating Tc via the density of states at the Fermi level and the McMillan formula systematically fails to yield the observed Tc variation. On the other hand, spin fluctuation theory pairing calculations allow us to consistently explain the Tc increase with doping. All alkali doped materials Ba1-xAxTi2Sb2O (A = Na, K, Rb) are described by a sign-changing s-wave order parameter. Susceptibilities also reveal that the physics of the materials is controlled by a single Ti 3d orbital.

Realtà – le prime – nelle quali degrado urbanistico e disagio sociale rappresentano i caratteri salenti, che si coniugano con povertà, conflittualità e criminalità. Elementi che caratterizzano e danno corpo a quegli spazi specifici, prodotto di un aggregato urbano privo di un’anima, di un’identità, che genera, in chi li osserva dall’esterno, un senso di disorientamento, di spaesamento.

description: We study the clustering of LRG galaxies in the latest spectroscopic SDSS data releases, DR6 and DR7, which sample over 1 Gpc^3/h^3 to z=0.47. The 2-point correlation function $\xisp$ is estimated as a function of perpendicular $σ$ and line-of-sight $π$ (radial) directions. We find a significant detection of a peak at $r\simeq 110$Mpc/h, which shows as a circular ring in the $σ-π$ plane. There is also significant evidence for a peak along the radial direction whose shape is consistent with its originating from the recombination-epoch baryon acoustic oscillations (BAO). A $\xisp$ model with no radial BAO peak is disfavored at $3.2σ$, whereas a model with no magnification bias is disfavored at $2σ$. The radial data enable, for the first time, a direct measurement of the Hubble parameter $H(z)$ as a function of redshift. This is independent from earlier BAO measurements which used the spherically averaged (monopole) correlation to constrain an integral of $H(z)$. Using the BAO peak position as a standard ruler in the radial direction, we find: $H(z=0.24)= 79.69 \pm 2.32 (\pm 1.29)$ km/s/Mpc for z=0.15-0.30 and $H(z=0.43)= 86.45 \pm 3.27 (\pm 1.69)$ km/s/Mpc for $z=0.40-0.47$. The first error is a model independent statistical estimation and the second accounts for systematics both in the measurements and in the model. For the full sample, $z=0.15-0.47$, we find $H(z=0.34)= 83.80 \pm 2.96 (\pm 1.59)$ km/s/Mpc.

description: Investment in farm capital underpins Scottish Government goals for a sustainable and productive industry. We examine the intentions and past behaviours for on-farm and off-farm investments. Using the farmer intentions survey - a survey of 2,494 Scottish farmers conducted in 2018 - we find that large numbers of farmers have declared an increase in the capital value of the farm and have mostly reinvested in their buildings and machinery over the last five years - with most of the investment in the medium to very large farm sizes. Very large farms are investing the most in capital around agricultural production and medium sized farms have invested the most in agroforestry. On average 18% of farms have increased their off-farm investments. As regards intentions to invest, a large proportion of the farms who did not invest in the last five years have no intention of investing in the next five years. Looking at the factors which drive investment in agricultural capital, we find this is characterised by higher incomes and larger farm size, but also succession factors as well attitudes to risk taking. In addition, those farmers who declared a more positive attitude towards Brexit also intended to increase farm capital investment. We also find a greater intention to invest in agroforestry across all farm sizes compared to the last five years which may be indicative of changes expected in the replacement of the CAP. Framing an agricultural policy for Scotland should focus on encouraging sustainable investment in both agricultural and environmental capital to encourage efficiency gains and meet climate and biodiversity targets in the future. Barriers exist to investment and these are structural - in terms of size and income - but also behavioural - e.g. attitudes towards investment, as well as generational - in terms of succession and entry into the sector.

description: Cramér-type large deviations for means of samples from a finite population are established under weak conditions. The results are comparable to results for the so-called self-normalized large deviation for independent random variables. Cramér-type large deviations for the finite population Student $t$-statistic are also investigated.

description: Dal 27 al 29 novembre, a Bolzano, negli spazi del Four Points By Sheraton Hotel, si è svolta la XXII Conferenza della Federazione delle Associazioni Scientifiche per le Informazioni Territoriali e Ambientali (ASITA). ASITA raggruppa quattro associazioni scientifico-culturali italiane accumunate dall’esigenza di raccordare, sotto un’unica regìa, la conoscenza, l’analisi e la gestione dei dati geografici e delle informazioni ambientali che ognuna porta avanti sotto uno specifico profilo corrispondente alla propria mission: dal rilevamento, da terra e dallo spazio, al processamento e alla rappresentazione dei dati utilizzando tecniche GIS. Sorta nel 2009, dopo due conferenze “preparatorie” (la prima nel 2007 alla fiera di Parma e a Napoli l’anno successivo) durante le quali si è registrato il comune interesse per l’interscambio tra modalità di approccio all’analisi e al trattamento differenziato delle informazioni territoriali e ambientali, la federazione ha sancito la possibilità di un confronto culturale e scientifico inerente appunto il rilievo topografico (per tradizione della SIFET, la Società Italiana di Fotogrammetria e Topografia), l’acquisizione dei dati tramite telerilevamento (campo di ricerca dell’AIT, l’Associazione Italiana per il Telerilevamento), la loro rappresentazione (di storico interesse dell’AIC, l’Associazione Italiana di Cartografia) e il processamento e divulgazione delle tecniche GIS (curato da AM-FM GIS/Italia che si occupa di sistemi informativi geografici e sue applicazioni e diffusione), colmando così dei vuoti tra saperi e consentendo lo sviluppo di nuove forme di conoscenza integrate, pure non rinunciando alla specifica cultura settoriale.

description: In Vibrationsanalysen von Power-Tools wird ermittelt, welchen Vibrationsemissionen der Anwender während der Anwendung ausgesetzt ist. Im System Power-Tool stehen Anwender, Maschine und Untergrund in einem direkten Leistungsfluss und beeinflus-sen sich durch ihre dynamischen Eigenschaften gegenseitig. Die Güte einer Vibrati-onsanalyse hängt sowohl vom Anwender als auch von der Maschine und dem Unter-grund ab. Ein Ansatz, zur Verbesserung dieser Güte, ist der Einsatz von physischen Ersatzsystemen für Anwender und Untergrund. Die Norm DIN EN ISO 28927-10 regelt die Ermittlung der Schwingungsemission bei Bohrhämmern und bietet eine technische Lösung an, um die Streuung aus dem Kontakt Werkzeug-Untergrund zu verbessern. Neben dieser technischen Lösung sind weitere Systeme am Markt vorhanden, mit denen der Kontakt zwischen Werkzeug und Untergrund nachgebildet werden kann. Bei den vorhandenen Systemen ist nicht sichergestellt, in welchem Anwendungsbereich sie Gültigkeit besitzen und wie realitäts-nah beziehungsweise wie reproduzierbar die Vibrationen im Vergleich zum Hammerbohren in Beton sind. Für realitätsnahe und reproduzierbare Vibrationsanalysen von Bohrhämmern liegt im Stand der Forschung kein geeignetes validiertes physisches Ersatzsystem vor. In dieser Forschungsarbeit werden die Stoßzahl und das Bohrmoment verwendet, um die mechanisch-dynamischen Wechselwirkungen im Kontakt Bohrer-Beton zu beschreiben. Die Bohrmomente und Stoßzahlen werden in einer Studie für unterschiedliche Bohrtiefen, Betonsorten und Vorschubkräfte quantifiziert. Mittels eines Simulationsmodells werden die Stoßzahlen in einen physischen Ersatzuntergrund überführt und in einer Studie verifiziert. Abschließend werden in einer Vibrationsanalyse die Be-schleunigungen am Hauptgriff und am Gehäuse des Bohrhammers ermittelt und mit den Beschleunigungen beim Hammerbohren in Beton vergleichen. Mit dem in dieser Forschungsarbeit entwickelten Ersatzuntergrund können Vibrationsanalysen realitätsnah und mit reduzierter Streuung im Vergleich zum Hammerbohren in Beton durchgeführt werden. Die Streuungen aus dem Stoßkontakt Bohrer-Beton werden durch den Einsatz einer Kombination aus Ringfeder und Graugusszylinder im Vergleich zum Hammerbohren in Beton reduziert. Die Aufprägung eines dem Hammerbohren in Beton äquivalenten Bohrmoments, führt zu einem realitätsnahen Be-triebspunkt des Bohrhammers. Diese Forschungsarbeit leistet einen Beitrag zum For-schungsschwerpunkt Ersatzuntergrundsysteme.
The Impact of Hyper-Parameter Tuning for Landscape-Aware Performance Regression and Algorithm Selection

description: Automated algorithm selection and configuration methods that build on exploratory landscape analysis (ELA) are becoming very popular in Evolutionary Computation. However, despite a significantly growing number of applications, the underlying machine learning models are often chosen in an ad-hoc manner. We show in this work that three classical regression methods are able to achieve meaningful results for ELA-based algorithm selection. For those three models -- random forests, decision trees, and bagging decision trees -- the quality of the regression models is highly impacted by the chosen hyper-parameters. This has significant effects also on the quality of the algorithm selectors that are built on top of these regressions. By comparing a total number of 30 different models, each coupled with 2 complementary regression strategies, we derive guidelines for the tuning of the regression models and provide general recommendations for a more systematic use of classical machine learning models in landscape-aware algorithm selection. We point out that a choice of the machine learning model merits to be carefully undertaken and further investigated.

description: Il 18 gennaio 2019 si è svolto, presso la sede romana del CNR, un incontro pubblico celebrativo dei 40 anni dell’A.Ge.I., Associazione dei Geografi Italiani. L’aula Marconi che ha ospitato l’evento, pur ampia, era gremita di geografe/i provenienti da tutte le sedi universitarie italiane che hanno partecipato all’evento con la volontà di testimoniare il loro riconoscersi nell’associazione e nel riconoscere a essa un ruolo di primaria importanza tra i sodalizi geografici, svolto in questi 40 anni di attività. La giornata è stata anche l’occasione per ricordare Alberto Di Blasi, fondatore e presidente dell’A.Ge.I. dal 1990 al 1997 e dal 2001 al 2009, a un anno dalla sua scomparsa. Gli interventi che si sono succeduti hanno visto i relatori affrontare molti temi di grande attualità per la geografia. Oltre a una ricostruzione critica della storia e delle attività dell’A.Ge.I., sono stati affrontati anche molti altri temi come il ruolo del sapere geografico nella società contemporanea, i rapporti tra i vari sodalizi geografici e tra questi e le istituzioni preposte alla ricerca scientifica, l’internazionalizzazione degli studi geografici italiani, la difficile condizione delle/dei geografe/i nelle università italiane. Quindi una giornata ricchissima di spunti e molto istruttiva soprattutto per le/i geografe/i delle generazioni più recenti che hanno potuto conoscere e ricostruire una storia della geografia italiana che difficilmente si trova nei testi.

description: Gestione del rischio, non più gestione delle catastrofi. È questo il nuovo indirizzo, dettato al livello internazionale, che deve seguire le aree più esposte ai disastri ambientali del pianeta. Gli ultimi tragici episodi (dal terremoto del Centro Italia del 2016-2017, alle devastanti alluvioni del 2018, fino alle recenti eruzioni dell’Etna con relative scosse sismiche in Sicilia) non fanno che ribadire che l’Italia deve convivere con rischi ambientali di ogni genere, visto che, purtroppo, possiede un lunghissimo catalogo storico di eventi, spesso catastrofici, in grado di sconvolgere popolazioni e trasformare il territorio nel breve e nel lungo periodo.
