Ethnies

In Western Europe, with the creation of a "United Europe", many people think that a mosaic of local or minoritary historical identities will develop, more and more distinctive and imposing : local and minoritary compared to europe and to the states and other politico-administrative groups that compose itactually or that will compose it tomorrow. And the movements of ethnic revendication often show the wish or the hope of seeing thelocal identities liberated from their constraints and destined to play new and important roles, thanks to the new equilibrum of United Europe. Western nationalisms and patriotisms are weakened because, from now on, theworld seems to bea more andmore unique group, a whole, and that goes for humanity living there too, although the oekoumene isdevided into rich and dominating countries on one side, and poor and dominated countries on the other side, therefore redefining two original macro-identities on a planetary scale : the rich and the poor. And it isof small importance that this should ojten reproduce itself on a smaller scale in the west and inside the territory of a unique state

La narrativa sarda recente: uno sguardo dall’interno

This is Giulio Angioni’s report which he presented at the opening of our conference. Giulio, our dear  friend and colleague, departed this world last January leaving an intellectual vacuum behind him that is  not easy to fill, together with heartfelt regret in all those who were close to him and who had the chance  to talk to him. Not only we do wish to remember his wisdom and erudition as an anthropologist, his  original gaze on Sardinian reality and the precious scientific contributions he gave to us, but let us also  recall his activity as a narrator and as an artist. This allowed him to describe and represent our land in all  its problematic aspects: two activities which, as he says here, must necessarily be linked together.   In these pages, Giulio Angioni reviews the literary activity and production in Sardinia, and the dialectical, and  sometimes contradictory, coexistence of two languages on the Island, both of which are also used in Literature.  This paper then takes into account the literary work of Grazia Deledda who, in many ways, was the initiator of  the “new” Sardinian literature. Indeed, she was almost an archetype for Sardinian narrators to come, as she  introduced a modern approach in narrating Sardinia. Her reception was great in Sardinia, but above all in and  outside Italy and the novels she set outside Sardinia were always a flop. This leads to a reflection on the  relationship that Sardinian narrators (must) have with their own land, and on what the non-Sardinian reader  expects from the narrators of Sardinia, namely, on the relationship between global and local.   [His friends on the Rhesis editorial staff]Pubblichiamo qui la comunicazione con cui Giulio Angioni ha aperto il Seminario. L’Amico e Collega Giulio  si è congedato da questo mondo lo scorso gennaio ed ha lasciato in noi un vuoto intellettuale che non sarà facile  riempire e un rimpianto affettivo in chi gli è stato vicino e in chi con lui ha dialogato. Vogliamo qui ricordare la  sua sapienza di antropologo, il suo originale sguardo sulla realtà sarda e i preziosi contributi scientifici che ci ha  donato; ma anche la sua attività di narratore e di artista con la quale pure ha descritto e problematicamente  rappresentato la nostra terra: due attività che, egli stesso qui dice, per lui non potevano che essere connesse.   In queste pagine, Giulio Angioni fa il punto sull’attività e sulla produzione letteraria in Sardegna; sulla  questione e sulla convivenza dialettica, a volte contraddittoria, di due lingue presenti nell’Isola, entrambe  impiegate anche in Letteratura; sulla problematica e sulle polemiche cui questa duplicità ha dato e dà luogo.  L’articolo prende poi in considerazione l’opera di Grazia Deledda, iniziatrice, per molti versi, della “nuova” letteratura sarda, quasi un archetipo per i narratori sardi a venire. Il suo successo fu grande in Sardegna, ma  soprattutto in Italia e fuori d’Italia; e quando la Deledda non ambientò in Sardegna i suoi romanzi, questi  furono un flop. Ciò porta a riflettere sul rapporto che i narratori sardi intrattengono con la propria terra, e su  ciò che i lettori non sardi si aspettano dai narratori di Sardegna: sul rapporto fra globale e locale.   [gli amici della Redazione di Rhesis

Annotazioni su archeologi(a) e antropologi(a)

This  essay discusses  the idea that archaeology, precisely like anthropology, must continually deal with the Western millennial habit to divide life into different areas (doing, saying, thinking, feeling ...) and sort them into hierarchies. Perhaps the greatest cognitive and practical task of every anthropology and archaeology is to be able to connect together at par, thus turning them into a 'useful 'truth', either that the whole world is the same  and that “in Rome do as Romans do”, i. e. to understand and use the positivity and avoid the negativity of prescriptions wanting that “wright or wrong, my country”. Following only the human invariance or identity, or just following only the variety of ways of living, has caused great oversights and serious troubles. Archaeologists and anthropologists should know better than others that if men are always the same and always different, then they cannot be reduced  to their identity of species or to their different lifestyles.Il centro di queste annotazioni è che l’archeologia quanto l’antropologia devono continuamente fare i conti con l’abitudine millenaria occidentale a scindere la vita in vari ambiti (il fare, il dire, il pensare, il sentire…) e a ordinarli in gerarchie d’importanza. Forse il maggiore compito conoscitivo e pratico di ogni antropologia e di ogni archeologia è riuscire a tener connessi alla pari, facendoli così diventare utili ‘verità’, sia che tutto il mondo è paese e sia che paese che vai usanza che trovi, per capire e usare il positivo ed evitare il negativo di prescrizioni che vogliono moglie e buoi dei paesi tuoi, o che wright or wrong, my country. Attenersi solo all’umana invarianza o identità, o attenersi solo alla varietà dei modi di vivere, è causa di grandi sviste e di più fatali guai. Archeologi e antropologi dovrebbero sapere meglio di altri che se gli uomini sono sempre identici e sempre diversi, non sono riducibili né alla loro identità di specie né alla loro diversità di modi di vita

Site effect studies following the 2016 Mw 6.0 Amatrice Earthquake (Italy): the Emersito Task Force activities

On August 24, 2016, at 01:36 UTC a MW 6.0 earthquake struck an extensive area of the Central Apennines (Italy) be-tween the towns of Norcia and Amatrice. Due to the mainshock magnitude and the widespread damaging level of build-ings in the epicentral area, the Emersito task force has been mobilized by the Istituto Nazionale di Geofisica e Vulcanologia (INGV). The aim of Emersito is to carry out and coordinate the monitoring of local site effects, caused by geological and geomorphological settings. During the first days of the seismic emergency, Emersito installed a tempo-rary seismic network for site effect studies at 4 municipalities close to the epicentral area (Amandola, Civitella del Tronto, Montereale and Capitignano), using 22 stations equipped with both velocimetric and accelerometric sensors. The selection of the sites where stations have been installed was mainly driven by the proximity to the epicentral area (without interfere with the rescue operations) and by peculiar geologic and geomorphologic settings (topographic irregu-larities, fault zones, alluvial plains). Preliminary analyses performed on ambient noise and aftershocks signals show that directional amplification effects may have occurred at stations installed on the top of topographic irregularities. We also observed the lengthening and amplification of the seismograms and a variability of the peaked frequency across the sedi-mentary basin between Montereale and Capitignano, probably related to a different thickness of the deposits. Further analyses are necessary to assess the correlation with surface geology.Published4T. Sismologia, geofisica e geologia per l'ingegneria sismica1SR.

Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks

A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at root s = 8 TeV. The data correspond to an integrated luminosity of 19.7 fb(-1). The search considers HH resonances with masses between 1 and 3 TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t (t) over bar events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 confidence level for the product of the production cross section and branching fraction sigma(gg -> X) B(X -> HH -> b (b) over barb (b) over bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with amass scale Lambda(R) = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV

Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| < 0.03 at 95% confidence level.

Performance of the CMS muon trigger system in proton-proton collisions at √s = 13 TeV

The muon trigger system of the CMS experiment uses a combination of hardware and software to identify events containing a muon. During Run 2 (covering 2015-2018) the LHC achieved instantaneous luminosities as high as 2 × 10 cm s while delivering proton-proton collisions at √s = 13 TeV. The challenge for the trigger system of the CMS experiment is to reduce the registered event rate from about 40 MHz to about 1 kHz. Significant improvements important for the success of the CMS physics program have been made to the muon trigger system via improved muon reconstruction and identification algorithms since the end of Run 1 and throughout the Run 2 data-taking period. The new algorithms maintain the acceptance of the muon triggers at the same or even lower rate throughout the data-taking period despite the increasing number of additional proton-proton interactions in each LHC bunch crossing. In this paper, the algorithms used in 2015 and 2016 and their improvements throughout 2017 and 2018 are described. Measurements of the CMS muon trigger performance for this data-taking period are presented, including efficiencies, transverse momentum resolution, trigger rates, and the purity of the selected muon sample. This paper focuses on the single- and double-muon triggers with the lowest sustainable transverse momentum thresholds used by CMS. The efficiency is measured in a transverse momentum range from 8 to several hundred GeV
