Modelli di consumo e nuovo paradigma della sostenibilità: i Gruppi di Acquisto Solidale in Sicilia
2010
European society, with its steadily increased welfare levels, is not only concerned about food (safety, prices), but also on other aspects such as biodiversity loss, landscape degradation, pollution of water, soil and atmosphere. To a large extent these concerns can be translated into a wider concept named sustainable development defined as a normative concept by Morgan and Sonnino (2008). Sustainability in the food chain means approaching a new emerging vision of a sustainable agro-food system introducing an institutional dimension to take into account. Among different attempts to conjugate such concepts, there is one that is taking place in many Regions of Italy. In the last years spontan…
Diferencias según género en las prácticas y los significados asociados al consumo de éxtasis entre jóvenes de la movida dance en Buenos Aires
2010
El trabajo encara en primer lugar cómo fue el desarrollo de la movida electrónica en la ciudad de Buenos Aires y cómo fue la introducción del consumo de éxtasis como droga recreativa ligada a ella. Se describe luego la metodología del estudio realizado con 150 jóvenes que participan de este tipo de encuentros (componente cuantitativo) y las entrevistas realizadas con 30 jóvenes y disk jockeys (componente cualitativo). Se analizan los datos demográficos de la muestra y las diferencias encontradas según sexo en cuanto a nivel educativo y tipo de ocupación. Otra variable explorada es el nivel de gastos por salida en el que incurren los jóvenes y las diferencias por sexo encontradas en relación…
El Derecho Fundamental de Acceso a la Justicia de los Consumidores
2018
El acceso a la justicia es hoy en día un Derecho fundamental reconocido en la Constitución española en el artículo 24 a través del Derecho a la tutela judicial efectiva, así como el derecho a la asistencia justicia gratuita para aquellos que acrediten insuficiencia de recursos para litigar de acuerdo con el artículo 119 de la Constitución española. Sin embargo, estos derechos se desdibujan cuando intentamos reivindicar los derechos de los consumidores. En este trabajo analizamos cómo Cappelletti teorizó, a través de su obra General Report Access to justice, las tres olas básicas para conseguir derribar las barreras que impiden el acceso a la justicia. Esta teoría refleja los pasos seguidos …
Ad “Uso e Consumo” del suolo
2021
Parlare di consumo di suolo significa affrontare di una questione attuale che pone le sue basi in una lunga storia complessa e articolata. La complessità e l'incertezza del concetto di consumo di suolo è da ricercare anche nella sua storia che è legata a quella dell'uso del suolo. Pertanto, definire chiaramente il termine consumo di suolo è difficile nonostante una ricca letteratura sull'argomento sia oggi disponibile. Si potrebbe dire che il consumo di suolo deve essere inteso come un processo antropico che opera una trasformazione, attraverso la realizzazione, soprattutto nelle aree agricole, di infrastrutture di vario tipo che spesso distruggono le caratteristiche ambientali del territor…
Análisis de la producción y el consumo de información en los artículos españoles sobre bibliometría
1996
We analyze Spanish production of papers on bibliometrics published in Spanish scientific journals and the use of information through the method of bibliographic reference analysis. Publications have been obtained from IME, ICYT and ISOC databases. The number of papers was 101 , with 1848 citations. The most important citations are to journal articles and Spanish publications, but <i>Scientometrics</i> is the most cited journal. Results seem to show that bibliometrics is a young discipline in our country, with an important role of classic authors. Difficulties of access to foreign bibliography produce a high use of Spanish publications. Medicine and Psychology are the most influe…
The potential link between episodes of diverticulitis or hemorrhoidal proctitis and diets with selected plant foods : a case-control study
2021
Diverticulitis and hemorrhoidal proctitis in the population are significant public health problems. We studied the potential association between the intake of certain plant foods and diverticulitis or hemorrhoidal episodes through a case–control study including 410 cases and 401 controls. We used a semiquantitative food frequency questionnaire. The intake was additionally quantified according to a 24 h recall. The plant foods or derived food products were categorized by their main chemical components into ethanol, caffeine/theine/theobromine, capsaicin, alliin, acids, eugenol, and miscellaneous foods such as curcumin. The mean score for overall intake of plant foods under consideration was …
Drug use, family support and related factors in university students. A cross-sectional study based on the uniHcos Project data
2019
Objective: To assess the prevalence of illegal drug use in college students on any previous occasion, during the previous year and the previous month, and to analyze the relationship between illegal drug use and family support and other factors. Methods: A cross-sectional study using data from students participating in the uniHcos project (n = 3767) was conducted. The prevalence and age of onset of consumption of cannabis, non-prescription sedatives, stimulants and depressants was evaluated. Polyconsumption was also assessed. The independent variables were: family support, age, residence, and employment status. To determine the factors related to drug use multivariate logistic regression mo…
Statistical and biological gene-lifestyle interactions of MC4R and FTO with diet and physical activity on obesity: new effects on alcohol consumption
2012
Background: Fat mass and obesity (FTO) and melanocortin-4 receptor (MC4R) and are relevant genes associated with obesity. This could be through food intake, but results are contradictory. Modulation by diet or other lifestyle factors is also not well understood. Objective: To investigate whether MC4R and FTO associations with body-weight are modulated by diet and physical activity (PA), and to study their association with alcohol and food intake. Methods: Adherence to Mediterranean diet (AdMedDiet) and physical activity (PA) were assessed by validated questionnaires in 7,052 high cardiovascular risk subjects. MC4R rs17782313 and FTO rs9939609 were determined. Independent and joint associati…
Effect of Chitin Whiskers on the Molecular Dynamics of Carrageenan-Based Nanocomposites
2019
[EN] Films of carrageenan (KC) and glycerol (g) with different contents of chitin nanowhiskers (CHW) were prepared by a solution casting process. The molecular dynamics of pure carrageenan (KC), carrageenan/glycerol (KCg) and KCg with different quantities of CHWs as a filler was studied using dielectric relaxation spectroscopy. The analysis of the CHW effect on the molecular mobility at the glass transition, T-g, indicates that non-attractive intermolecular interactions between KCg and CHW occur. The fragility index increased upon CHW incorporation, due to a reduction in the polymer chains mobility produced by the CHW confinement of the KCg network. The apparent activation energy associated…
MOF-Mediated Synthesis of Supported Fe-Doped Pd Nanoparticles under Mild Conditions for Magnetically Recoverable Catalysis**
2020
Metal–organic framework (MOF)-driven synthesis is considered as a promising alternative for the development of new catalytic materials with well-designed active sites. This synthetic approach is used here to gradually transform a new bimetallic MOF, with Pd and Fe as the metal components, by the in situ generation of aniline under mild conditions. This methodology results in a compositionally homogeneous nanocomposite formed by Fe-doped Pd nanoparticles that, in turn, are supported on iron oxide-doped carbon. The nanocomposite has been fully characterized by several techniques such as IR and Raman spectroscopy, TEM, XPS, and XAS. The performance of this nanocomposite as an heterogeneous cat…
