The need of political governance: The political sphere as main thrust and guarantor on Walzer’s theory

2014

Tomando como pretexto la teoría política de Walzer, el presente artículo pretende mostrar la necesidad de política en los tiempos y sociedades actuales. A pesar de lo depauperada y defenestrada que ésta pudiera parecer, sigue siendo necesario articular su papel en nuestras sociedades y mostrar su rol clave para librarnos de problemas tan omnipresentes como puede ser la corrupción en nuestros días. Para ello trataremos de indagar en cuál es el papel de la política y cómo es su relación con la sociedad civil y otras esferas de actuación, poniendo en valor su necesidad. Using as a pretext Walzer’s political theory, this article aims to show the need for politics in our times and contemporary s…

Labile carbon addition affects soil organisms and N availability but not cellulose decomposition in clear-cut Norway spruce forests

2014

We assessed the effects of sucrose addition on the biological and chemical properties of organic soil in clear-cut Norway spruce forests managed with or without wood-ash fertilization and mechanical site preparation. Sucrose addition increased the abundances of enchytraeids and tardigrades and soil moisture percentage in the clear-cut areas. Sucrose also increased nematode abundance in the non-fertilized plots. Sucrose reduced the pool of waterextractable NH4-N in the soil in the first year, but increased it in the second year. Sucrose addition did not affect the decomposition rate of cellulose strips. The biomass of ground vegetation was not affected by sucrose. Carbohydrate addition seems…

Perception of melodic complexity: a cross-cultural investigation

Perception of quality and complexity in wine and their links to varietal typicality: An investigation involving Pinot noir wine and professional tast…

2020

International audience; Quality and complexity are abstract terms employed frequently to describe a wine's overall attributes. In the present study, we investigated: (i) attributes driving wine professionals' judgments of quality and complexity in Pinot noir wines; (ii) the relation between these two abstract concepts; and (iii) association of each concept with varietal typicality. Twenty-two wine professionals evaluated 18 New Zealand Pinot noir wines in both clear and opaque glassware via two sensory tasks, a descriptive rating task and an 8-attribute, perceived complexity questionnaire. Sensory data were associated with wine UV-spectrophotometry colour measures to aid interpretation of t…

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 …

Femoral Versus Radial Artery Access for CTO PCIs: Is This the Final Round?

2022

Historically, cardiac catheterization has been performed via transfemoral access (TFA). Although TFA remains necessary in multiple diagnostic and interventional settings, this technique has been associated with vascular access site complication rates ranging from 2% to 6%, prolonged hospital stay, and more deaths compared with radial artery access. Furthermore, safe utilization of the femoral artery can be compromised by abdominal obesity, atherosclerosis at the puncture site, and antithrombotic therapy, all which increase the bleeding risk.1 In the last decade, transradial artery access (TRA) emerged as the recommended approach for percutaneous coronary interventions (PCI), particularly in…

Speciation of organic matter in natural waters. Interaction of polyacrylates with the major cation components of seawater

2004

The speciation of some high molecular weight polycarboxylates was studied in different ionic media. Polyacrylates here investigated (W=2.0, 5.1 and 20.0 kDa) form weak species with alkali metal cations (K=102 mol l1, t=25 jC, I=0 mol l1) and quite stable complexes with alkaline earth metal cations (K>106 mol l1, t=25 jC, I=0 mol l1). Results are reported from experiments performed in a multicomponent electrolyte solution simulating the major composition of seawater (artificial seawater). Protonation constants in this medium are expressed as a polynomial function of S1/2 (S=salinity) and the sharp lowering with respect to values obtained in non-interacting aqueous tetraalkylammonium salts ca…

Determination of enzymatic activities using a miniaturized system as a rapid method to assess soil quality

2014

Soil quality determination requires the analysis of a number of soil attributes using different approaches. In recent years, one of the most promising approaches has been the determination of enzymatic activities. Generally, only a few enzymes have been analysed and related with other parameters, such as total carbon, nitrogenous content or microbial biomass carbon. The aim of this work was to investigate the possible use of the API ZYM strip, a semi-quantitative miniaturised system that determines 19 enzymatic activities, to study soil quality. To this end, we tested the system in different soil types, including albicArenosols, mollicLeptosols, rendzicLeptosols, haplicLeptosols, and calcar…
