The dynamic nature of meaning

This paper wants to be a contribution, mainly of philosophical character, to a new current of thought and research in semantics that have been defined the “dynamic turn ” in the study of meaning (cf. Peregrin 2003). The central point of this approach to meaning is that there is not such a thing like a precise literal meaning of a word or expression, bu

Enxaqueca hemiplégica familiar - um relato de caso / Familial hemiplegic migraine - a case report

A enxaqueca hemiplégica familiar (EHF) é um subtipo de enxaqueca com aura, caracterizado por fraqueza motora, em que ao menos um familiar de primeiro ou segundo grau também possua o mesmo diagnóstico. A sua sintomatologia está relacionada aos sintomas clássicos da aura, descritos acima, e à cefaleia, logo, o paciente pode apresentar perturbações na consciência, hemianopsia, afasia, letargia, hemiparesia, disfagia, febre, confusão mental, sendo, muitas vezes, confundida e tratada como epilepsia (2–6)

Logic and Pragmatism: Selected Writings of Giovanni Vailati

International audienceLogic and Pragmatism features a number of the key writings of Giovanni Vailati (1863–1909), the Italian mathematician and philosopher renowned for his work in history of mechanics, geometry, logic, and epistemology. The selections in this book—many of which are available here for the first time in English—focus on Vailati’s significant contributions to the field of pragmatism. Two introductory essays by the volume’s editors outline the traits of Vailati’s pragmatism and provide insights into the scholar’s life

Structural Control at Monte Somma and Vesuvio during the Last 5600 Years through Time and Space Distribution of Volcanic Vents

Vesuvio is likely the most if not one of the most dangerous volcanoes in the world. It is an active volcano, quiescent since 1944. The activity of the Monte Somma and Vesuvio volcanic complex is commonly referred to as two central volcanic edifices, namely Monte Somma and Vesuvio. Nevertheless, the opening of numerous eruptive fissures and related vents have characterized Monte Somma and Vesuvio throughout their lives. Spatter cones, spatter ramparts, and related eruptive fissures are disseminated downslope of Vesuvio’s main cone and on the southern slopes of the volcano. Similarly, cinder cones, spatter cones, and welded spatters are distributed in the sequence cropping out on the Monte Somma cliff and on the northern slopes of Monte Somma. In this work, a total of 168 eruptive vents have been identified and characterized in a GIS environment in which field data have been merged with relevant information from historical maps and documents. These vents have been arranged into units bounded by unconformities (Unconformity Bounded Stratigraphic Units) defining the eruptive history of the volcano. Alignments of vents and eruptive fissures within each unit have been compared with regional tectonic elements and the volcano-tectonic features affecting Monte Somma and Vesuvio during the last 5600 years, thus inferring that different structural trends were active in the different stratigraphic units. In particular, we show that the N300°–320° regional, Apennine, left-lateral, strike-slip fault system, the N040°–055° Torre del Greco direct fault system, the N70° and the EW fault system, and the generally NS oriented group of local brittle elements, all analyzed here, were differently active during the investigated time span. These tectonic trends might control the position of the eruptive fissures and vents in case of future unrest of the volcano

Insulin dynamics in young women with polycystic ovary syndrome and normal glucose tolerance across categories of body mass index.

BACKGROUND: Evidence favours insulin resistance and compensatory hyperinsulinemia as the predominant, perhaps primary, defects in polycystic ovary syndrome (PCOS). The aim of the present study was to evaluate insulin metabolism in young women with PCOS but normal glucose tolerance as compared with age, body mass index and insulin resistance-matched controls to answer the question whether women with PCOS hypersecrete insulin in comparison to appropriately insulin resistance-matched controls. RESEARCH DESIGN AND METHODS: Sixty-nine cases were divided according to their body mass index (BMI) in normal-weight (N = 29), overweight (N = 24) and obese patients (N = 16). Controls were 479 healthy women (age 16-49 y). Whole body Insulin Sensitivity (WBISI), fasting, and total insulin secretion were estimated following an oral glucose tolerance test (C-peptide deconvolution method). RESULTS: Across classes of BMI, PCOS patients had greater insulin resistance than matched controls (p<0.0001 for all the comparisons), but they showed higher fasting and total insulin secretion than their age, BMI and insulin resistance-matched peers (p<0.0001 for all the comparisons). CONCLUSION: Women with PCOS show higher insulin resistance but also larger insulin secretion to maintain normal glucose homeostasis than age-, BMI- and insulin resistance-matched controls

ARCHAEOMAGNETIC INVESTIGATION OF LATE ENEOLITHIC FURNACES UNDER THE ANCIENT BRONZE AGE VILLAGE OF CROCE DI PAPA, NOLA (ITALY)

The Copper Age marks the first stage of human’s use of metal. Eneolithic is commonly assumed to begin in the early 4th millennium BC in Southeastern Europe and at least 1,000 years earlier in the Middle East, where the majority of copper mines exploitation started. This study provides a chronological contribution to this matter. Our finding allows dating the beginning of the use of metal in the Campanian plain to the first half of the 3rd millennium BC
