No full textLa voce sintetizza le riflessioni scaturite da una ricerca etnografica svolta su un interessante caso di controversie tra culture locali e politiche internazionali di tutela
del patrimonio culturale immateriale: le Carresi del basso Molise. Si tratta di pratiche tradizionali in contrasto con le nuove sensibilità sui
diritti universali e sui valori fondamentali quali quelli etnico-religiosi, di genere, di orientamento
sessuale ai quali si sono più recentemente aggiunti quei sistemi rituali patrimoniali in cui
sono coinvolti, a vario titolo, gli animali. Contro questi ultimi si
sono scagliati i movimenti animalisti ravvedendovi atteggiamenti sevizianti e un antropocentrismo
arretrato in contrasto con nuovi orientamenti nelle relazioni tra specie diverse
improntate all’antispecismo e a un’idea dell’animale come
soggetto di diritto a tutti gli effetti. Da ciò è scaturita una vicenda giudiziaria a carico dei tre comuni molisani interessati dalla ricerca, che è stata risolta grazie alle perizie delle antropologhe e di veterinari esperti della razze animali coinvolte, e alla formulazione di un nuovo disciplinare delle corse rituali condiviso con i protagonisti grazie a una azione di mediazione effettuata dalle antropologhe
“Animals and/or humans: Ethnography and the mediation of ‘glocal’ conflicts in the Carresi of southern Molise (Italy)”
No full textAbstract The paper focuses around a particular legal controversy between a ceremonial system in a South-Central area of Italy, including oxen charts races with horses associated to the ritual competitions and animal rights movements' issues about suspected violence against animals involved in these ceremonials. Ethnographers have been deeply involved in this dispute resolution as experts on community practices and knowledge as well as other scholars in veterinary and animal genetics. The focus of the quarrel has been the ambivalence between local and ‘global hierarchies of value’.

Rietveld refinement of okayamalite, CA2SiB2O7: structural evidence for the B/Si ordered distribution
No full textThe structure of okayamalite from Arendal, Norway, was refined using the Rietveld method, with CoKα powder X-ray diffraction data (R(F) = 3.69%). Okayamalite exhibits a melilite-type structure, space group P4̄21m, with cell edges a = 7.1248(2), c = 4.8177(2) Å. Si and B are ordered on the T1 and T2 sites respectively, in agreement with the refined tetrahedral distances ( = 1.657 Å and =1.498 Å). In comparison with the other melilite-type compounds, the cation population in okayamalite leads to the minimum structural misfit between tetrahedral and square-antiprism layers
The crystal structure of alstonite, BaCa(CO3)2: An extraordinary example of 'hidden' complex twinning in large single crystals
Full text linkAlstonite, BaCa(CO3)2, is a mineral described almost two centuries ago. It is widespread in Nature and forms magnificent cm-sized crystals. Notwithstanding, its crystal structure was still unknown. Here, we report the crystal-structure determination of the mineral and discuss it in relationship to other polymorphs of BaCa(CO3)2. Alstonite is trigonal, space group P31m, with unit-cell parameters a = 17.4360(6), c = 6.1295(2) Å, V = 1613.80(9) Å3 and Z = 12. The crystal structure was solved and refined to R1 = 0.0727 on the basis of 4515 reflections with Fo > 4σ(Fo) and 195 refined parameters. Alstonite is formed by the alternation, along c, of Ba-dominant and Ca-dominant layers, separated by CO3 groups parallel to {0001}. The main take-home message is to show that not all structure determinations of minerals/compounds can be solved routinely. Some crystals, even large ones displaying excellent diffraction quality, can be twinned in complex ways, thus making their study a crystallographic challenge

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Abstract
BACKGROUND:
Hepatic resection is uncommon after liver transplantation (LT), but can be a graft-saving procedure in selected cases. Herein we describe the criteria, outcome, and timing of this procedure in our series.
METHODS:
Between January 1996 and December 2002, 397 LTs were performed in 367 recipients, of whom 12 patients (3.2%) subsequently underwent liver graft resections because of ischemic-type biliary lesions (ITBLs) (n = 5, 41.6%), segmental hepatic artery thrombosis (S-HAT)(n = 3, 25%), recurrent hepatocellular carcinoma (HCC) (n = 2, 16.6%), liver abscess (n = 1, 8.3%), or liver trauma (n = 1, 8.3%). The patients were divided into group 1 (n = 3 all with S-HAT) who underwent early resections (within 3 months of LT), and group 2 (n = 9) who underwent late resections (after 3 months). The outcomes and postoperative mortality ratio (within 30 days) were compared.
RESULTS:
The resections consisted of four left lobectomies, three right hepatectomies, two extended right hepatectomies, one segmentectomy, one anterior trisegmentectomy, and one right lateral sectoriectomy. The perioperative mortality rate was 66.6% in group 1 (one case of myocardial infarction and one of sepsis), and 22% in group 2 (one case of sepsis and one of hepatic failure).
CONCLUSIONS:
Late resections in stable patients with damage confined to the graft yield good prognosis. Even major resections are feasible graft-saving procedures. In contrast, early hepatic resections in S-HAT are associated with a worse outcome. Retransplantation should be considered the first-choice option. Sepsis significantly affects the postsurgical course
