Of Capital and Power Italian Late-Colonial Policies in Eritrea at the Onset of the Federation with Ethiopia
2021
Scholars of African history have often inquired into the relationship between government and business in the making of North-South relations after decolonization. The neo-colonial thesis maintained that the metropolitan governments undertook overt and covert actions to preserve the dominant position of their own multinational corporations in the newly independent African nations. Historians of British Africa have partially revisited this thesis, suggesting a more nuanced understanding of the relationship between political and economic actors. This article seeks to test these arguments in relation to the Italian case, looking at the early process of decolonization in Eritrea. In 1952, the fo…
Pliocene colonization of the Mediterranean by Great White Shark inferred from fossil records, historical jaws, phylogeographic and divergence time an…
2020
Aim: Determine the evolutionary origin of the heretofore poorly characterized contemporary Great White Shark (GWS; Carcharodon carcharias) of the Mediterranean Sea, using phylogenetic and dispersal vicariance analyses to trace back its global palaeo-migration pattern. Location: Mediterranean Sea. Taxon: Carcharodon carcharias. Methods: We have built the largest mitochondrial DNA control region (CR) sequence dataset for the Mediterranean GWS from referenced historical jaws spanning the 19th and 20th centuries. Mediterranean and global GWS CR sequences were analysed for genetic diversity, phylogenetic relationships and divergence time. A Bayes factor approach was used to assess two scenarios …
Występowanie pałeczek Legionella sp. w instalacjach wodnych obiektów użyteczności publicznej w województwie opolskim w latach 2010-2011
2012
CEL PRACY. Ocena kolonizacji sieci wodnej szpitali i obiektów użyteczności publicznej bakteriami Legionella sp. w województwie opolskim, w latach 2010 – 2011. MATERIAŁ I METODY. Ocenę przeprowadzono na podstawie wykonanych w latach 2010 – 2011 badań ciepłej wody w kierunku Legionella oraz meldunków sprawozdawczych MZ-56 i MZ-57 dotyczących zachorowań na choroby zakaźne. WYNIKI. Przeprowadzone badania ciepłej wody wykazały, że znaczący odsetek budynków użyteczności publicznej w woj. opolskim posiada skolonizowaną instalację wodną bakteriami Legionella sp. W grupie zbadanych obiektów, największy procent obiektów z kolonizacją sieci wodnej bakteriami Legionella sp. stanowią szpitale (2010 - 63…
Prefazione
2016
Le contaminazioni e le compresenze culturali, in ragione di esperienze ‘de-localizzanti’, trovano nella scrittura un fecondo luogo di espressione delle istanze più variegate e distanti del complesso problema della ‘convivenza’. Un tema che è d’obbligo oggi indagare non più nella ricerca di un luogo di confronto tra due elementi contrapposti che darebbero origine alla semplice somma di due parti, ma nella prospettiva di trovare una dimensione ‘terza’, intersoggettiva, in cui si ingenera la necessità – non sempre soddisfatta – della rinuncia alla esclusiva proiezione del sé. L’esperienza del superamento del ‘limite’, geografico e/o identitario, trova in sede letteraria il naturale luogo di el…
Oral colonization by Candida species in orthodontic patients before, during and after treatment with fixed appliances: A prospective controlled trial
2020
Este artículo se encuentra disponible en la siguiente URL: http://www.medicinaoral.com/medoralfree01/aop/57565.pdf Background: Orthodontic treatment with fixed appliances is associated with changes in oral microbiota, including increased Candida colonization. The Candida fungus can cause oral lesions and infections such as candidiasis and angular cheilitis, and is harmful to both the patient and the orthodontist. Poor hygiene facilitates the colonization of these microorganisms. The key aim was to quantify the colonization of C. albicans in patients prior to beginning orthodontic treatment, and during the treatment process. Material and Methods: A total of 124 patients (43 males and 80 fema…
Dinamiche di popolamento e processi di trasmissione culturale nel comprensorio madonita attraverso la ricostruzione della viabilità antica
2020
La ricerca sulle Madonie nasce con l’intenzione di approfondire l’evoluzione storica del popolamento sulla regione montana della Sicilia nord-occidentale. Il territorio, che solo in anni recenti è divenuto oggetto di più approfondite ricerche storico-archeologiche, si presenta estremamente ricco di risorse naturali e caratterizzato da un sostrato culturale variegato che abbraccia territori d’alta montagna, dediti ad una economia silvo-pastorale prettamente conservativa, e insediamenti costieri fortemente proiettati allo scambio e al commercio. A fine di comprendere lo sviluppo delle dinamiche d’insediamento di un’area molto estesa, si è proceduto anzitutto con la restituzione ipotetica dei …
Factors affecting between-lake variation in the occurrence of epidermal papillomatosis in roach,Rutilus rutilus(L.)
2009
The theory of island biogeography predicts that the probability of a species occupying an island depends on a dynamic equilibrium between extinction and colonization. Epidermal papillomatosis is a disease manifesting as skin tumours on fish. We studied the factors affecting the occurrence of the disease in roach, Rutilus rutilus (L.), in 34 lakes. The results of discrimination analysis suggest that maximum depth, percentage of the drainage area of the lake covered by lakes in the vicinity and altitude best identified diseased lakes. Comparison of diseased and non-diseased lakes revealed that lake area could also be regarded as a variable contributing to the occurrence of the disease. The sa…
Methicillin-resistant Staphylococcus aureus nasal colonization in a level III neonatal intensive care unit: Incidence and risk factors
2015
Objective: To describe epidemiologic features and identify risk factors for methicillin-resistant Staphylococcus aureus (MRSA) acquisition in a level III neonatal intensive care unit (NICU). Setting: A prospective, cohort study in a university-affiliated NICU with an infection control program including weekly nasal cultures of all neonates. Methods: Demographic, clinical, and microbiologic data were prospectively collected between June 2009 and June 2013. Molecular characterization of MRSA isolates was done by multilocus variable number tandem repeat fingerprinting, staphylococcal cassette chromosome mec typing, and on representative isolates by multilocus sequence typing and s. pa typing. …
tst1-positive ST22-MRSA-IVa in healthy Italian preschool children
2013
A survey was performed in May 2013 to assess methicillin-resistant Staphylococcus aureus (MRSA) nasal colonization in healthy children attending 26 municipal daycare centres in Palermo, Italy. Of the 500 children, ten (2 %) tested positive. Eight MRSA isolates were tst1-positive ST22-MRSA-IVa, spa t223; the other two isolates were identified as ST1-IVa and ST398-V, respectively. tst1-positive ST22-MRSA, spa t223 has been previously identified only in the Middle Eastern area.
Colonization of pressure ulcers by multidrug-resistant microorganisms in patients receiving home care
2011
Colonization and/or infection with multidrug-resistant microorganisms (MDRO) of pressure ulcers in patients receiving care at home have seldom been investigated. The objective of this study was to assess the prevalence of MDRO colonization in pressure ulcers of patients receiving home care in Palermo, Italy. Vancomycin-resistant Enterococcus (VRE), methicillinresistant Staphylococcus aureus (MRSA), and multidrug-resistant Gram-negative bacilli (MDRGN) were isolated, identifi ed, and characterized from pressure ulcers and selected home environment surfaces. Thirty-two patients were enrolled, of whom 12 were under antimicrobial therapy. Five patients had been admitted to hospital in the prece…
