Ring-opening metathesis of some strained bicyclic systems; stereocontrolled access to diolefinated saturated heterocycles with multiple stereogenic c…
2018
Ring-opening metathesis (ROM) of various unsaturated, constrained bicyclic ring systems has been investigated with the use of commercial ruthenium-based catalysts. Starting from various cyclodienes, the corresponding derived bicyclic lactone, lactam, and isoxazoline derivatives were submitted to ROM under ethenolysis. These functionalized, strained bicyclic systems afforded novel highly-functionalized diolefinated heterocyclic scaffolds in ROM reactions with stereocontrol, through the conservation of the configuration of the stereogenic centers of the starting compounds.
Impact of the knowledge society in the university and in scientific communication
2014
Over the last two decades, as a result of the introduction and intensive use of technologies for information and general knowledge, especially from the internet, the university is living in a process of complete transformation that affects it´s academic and organizational structures as well as the conception of educational methodology. The ICTs have demonstrated a need to establish coherent institutional strategies in their use and application, along with the possibility to expand the sphere of institutional action, in regards to general access to higher education. All of this shows an existing change from a model of education based on the transmission of knowledge, that was rather limited …
Factores facilitadores y barreras en la transición a la ciencia abierta: perspectiva de los agentes del sistema científico español
2022
This paper presents the results of a research study whose objective was to identify the facilitating factors and barriers that, in the opinion of representatives of the Spanish scientific community, impact the implementation of the new open science model in four areas: open access, open research data, research assessment and open peer review. A qualitative study was designed in which information was obtained through interviews with researchers, editors of scientific journals, representatives of assessment agencies and vice-chancellors, and through a focus group of librarians with expertise in aspects of open science. The enabling factors and barriers identified were related to the researche…
Copenhagen failure : a rhetorical treatise of how speeches unite and divide mankind
2010
The purpose of this treatise is to analyse five of the Copenhagen Climate Convention's main speeches to see how they supported or weakened the agreement possibilities in the convention. Particular focus will be on the elements that divide or unite negotiators and whether the summit's failing outcome is already built in the pre-planned speeches held at the main podium. Theoretically, the study builds on Kenneth Burke's identification thesis and Elizabeth L. Malone's climate change debate analysis. I combine these in my analysis using a revised version of Malone's argument family classification tool putting it into Burke's theoretical framework. The central concept is Burke's identification, …
Modelli ed evoulzione delle politiche
2008
Questo contributo propone alcune riflessioni utili all’inquadramento ed alla valutazione delle politiche a sostegno dell’innovazione. L’attenzione viene posta, in particolare, sull’evoluzione dello scenario nel quale opera l’impresa innovativa, sul ruolo di alcune tipologie di agglomerazioni emerse in questo nuovo scenario, quali le reti per l’innovazione ed i distretti tecnologici, sui sistemi territoriali innovativi nei quali i processi istituzionali hanno un ruolo sempre più importante, come nel caso dei sistemi d’innovazione nazionale e regionale, ed infine sulla questione dell’identificazione e della misurazione dei fattori chiave dell’innovazione utili per una valutazione delle politi…
Individuals’ Use of E-Mail Communication Genres in Open Source Software Community Building
2011
The advent of the participative Internet (Web 2.0) sheds a new light on traditional knowledge about communication practices. The role of information and communication technologies seems to be very central in managerial literature, while the human side of the issue is less considered. This paper argues that individuals establish communication genres as semantic templates for accomplishing their communicative projects. Communication genres are codes of default behavioral expectations resulting from recurrent communication actions over the time. By using semantic network analytical techniques, our argument is explored in a particular empirical setting, that is, a virtual community of open sour…
Medialne formy komunikowania obywateli z władzą
2017
The purpose of this paper is to characterize the media forms of the communication of citizens with the authorities. The discourse types with high occurrence in the public sphere of communication with the authorities are: open letter, petition, appeal, resolution of opinion, and comments in the social media (e.g. on Facebook). It can be said that these genres are a form of direct participation of citizens in the process of exercising power. They are the Citizen s weapon, a tool to exert influence on the fin a ł decisions of the authorities in matters of public life. The themes of public magazines are varied, most often „ hot cases ” referring to decisions currently taken by the authorities. …
The Abdominal Compartment Syndrome (ACS) after Abdominal Aortic Aneurysm (AAA) open repair
2009
Objective: The abdominal compartment syndrome (ACS) is a ‘condition in which increased tissue pressure in a confined anatomic space, causes decreased blood flow leading to ischaemia and dysfunction and leading to permanent impairment of function’. Methods: Between June 2007 and June 2008 we treated surgically 23 cases of AAA (14 in election and nine in emergency), with indirect intra- abdominal pressure (IAP) monitoring (intra-vescical catheter). Mean age was 68 (64–84) years, 19 males and 4 females. Mean transverse diameter was 6.2 cm (5.5–9.0). Preoperative diagnostic procedure was ultrasound and tomography when possible. All patients were managed in hypotensive hemostasis (restricting fl…
Mappe della contemporaneità. Visualizzare la complessità per vivere, comprendere, partecipare.
2020
Si propone una riflessione sulle modalità di visualizzazioni della complessità di contesti territoriali, rese possibili dalle tecnologie dell’informazione connesse agli open data; uno scenario che evidenzia la rilevanza oggi di strumenti e competenze del design della comunicazione e dell’informazione, proponendo una nuova centralità della “mappa”, strumento e modello contemporaneamente di conoscenza, rappresentazione e trasformazione del mondo. Il contributo indaga come le diverse declinazioni di visual mapping, che connettono un contesto reale fisico-geografico ai molteplici livelli di informazione disponibili, possono alimentare nei cittadini consapevolezza e partecipazione a supporto di …
Evaluation of the risk factors of asymptomatic vertebral fractures in postmenopausal women with osteopenia at the femoral neck
2016
To identify risk factors of asymptomatic vertebral fracture (aVF) in postmenopausal women with osteopenia at the femoral neck and to evaluate the association between the number of aVFs and the risk of major and hip osteoporotic fracture calculated with the FRAX(®) algorithm.Epidemiological case-series study with data collected transversally.728 postmenopausal women with osteopenia were included: 284 (39.0%) had aVF, of whom 200 (70.4%) had prior fragility fractures (FF). The likelihood of having an osteoporotic fracture in the next 10 years increased significantly with the number of aVF. The percentage of women with height loss, which was assessed as the difference between the greatest heig…
