Are Intercultural Competences at the Center of Job-Market Demands ?

2020

International audience; This chapter introduces the theoretical framework upon which this study was based before going on to set out the methodology used and detail the main results found. It discusses results in the light of scientific literature on the issue and their managerial implications. With the internationalization of organizational structures, the development of intercultural competences was often considered a strategic benefit. Indeed, companies are sensitive to the cultural diversity of their worldwide branches and to the international competences developed by their employees. Through organizational internationalization, intercultural competences become strategic resources. Alth…

APPLICAZIONE DI CRITERI E INDICATORI DELLA CERTIFICAZIONE PEFC DI GESTIONE FORESTALE SOSTENIBILE: DUE CASI STUDIO A CONFRONTO NEL TERRITORIO SICILIANO

2018

La Sicilia non ha ancora complessi forestali la cui gestione sostenibile sia stata certificata. Questo lavoro è volto a analizzare la possibilità di applicare i criteri e indicatori di certificazione di GFS secondo lo schema PEFC a due casi studio: i boschi del comune di Bivona (AG) e una foresta situata sulle Madonie (PA). Entrambi sono rappresentativi di ambienti ecologici diversi e importanti dell’isola. L’analisi pone in luce le criticità più significative della gestione attualmente adottata e la mancanza di comunicazione con i portatori d’interesse. Application of Criteria and Indicators of Sustainable Forest Management PEFC Certification: two case studies in Sicily Sicily currently ha…

Considering syntrophic acetate oxidation and ionic strength improves the performance of models for food waste anaerobic digestion.

2021

Current mechanistic anaerobic digestion (AD) models cannot accurately represent the underlying processes occurring during food waste (FW) AD. This work presents an update of the Anaerobic Digestion Model no. 1 (ADM1) to provide accurate estimations of free ammonia concentrations and related inhibition thresholds, and model syntrophic acetate oxidation as acetate-consuming pathway. A modified Davies equation predicted NH3 concentrations and pH more accurately, and better estimated associated inhibitory limits. Sensitivity analysis results showed the importance of accurate disintegration kinetics and volumetric mass transfer coefficients, as well as volatile fatty acids (VFAs) and hydrogen up…

The European Regional Convergence Process, 1980-1995: Do Spatial Regimes and Spatial Dependence Matter?

2002

International audience; The authors show that spatial dependence and spatial heterogeneity matter in the estimation of the ß-convergence process among 138 European regions over the 1980 to 1995 period. Using spatial econometrics tools, the authors detect both spatial dependence and spatial heterogeneity in the form of structural instability across spatial convergence clubs. The estimation of the appropriate spatial regimes spatial error model shows that the convergence process is different across regimes. The authors also estimate a strongly significant spatial spillover effect: the average growth rate of per capita GDP of a given region is positively affected by the average growth rate of …

Psychometric validation of the Italian translation of the gastrointestinal symptom-rating scale and quality of life in reflux and dyspepsia questionn…

2007

Background: Symptoms of heartburn and their impact on health-related quality of life (HR-QOL) are often evaluated in clinical trials. When a questionnaire is translated into a new language, a linguistic validation is necessary but not sufficient unless the psychometric characteristics have been verified. Objective: To document the psychometric characteristics of the Italian translation of the Gastrointestinal Symptom-Rating Scale (GSRS) and Quality of Life in Reflux and Dyspepsia (QOLRAD) questionnaire. Patients and methods: 152 consecutive patients with symptoms of heartburn (mean ±SD age 46.5 ± 16.2 years; 40.1% males) completed the Italian translation of GSRS, the heartburn version of QO…

A bizarre foreign body in the appendix: A case report.

2013

Foreign bodies are rare causes of appendicitis and, in most cases, ingested foreign bodies pass through the alimentary tract asymptomatically. However, ingested foreign bodies may sometimes remain silent within the appendix for many years without an inflammatory response. Despite the fact that cases of foreign-body-induced appendicitis have been documented, sharp and pointed objects are more likely to cause perforations and abscesses, and present more rapidly after ingestion. Various materials, such as needles and drill bits, as well as organic matter, such as seeds, have been implicated as causes of acute appendicitis. Clinical presentation can vary from hours to years. Blunt foreign bodie…

Trans-epithelial transport of the betalain pigments indicaxanthin and betanin across Caco-2 cell monolayers and influence of food matrix.

2012

Purpose: This study investigated the absorption mechanism of the phytochemicals indicaxanthin and betanin and the influence of their food matrix (cactus pear and red beet) on the intestinal transport. Methods: Trans-epithelial transport of dietary-consistent amounts of indicaxanthin and betanin in Caco-2 cell monolayers seeded on TranswellR inserts was measured in apical to basolateral (AP-BL) and basolateral to apical (BL-AP) direction, under an inwardly directed pH gradient (pH 6.0/7.4, AP/BL) mimicking luminal and serosal sides of human intestinal epithelium. The effect of inhibitors of membrane transporters on the absorption was also evaluated. Contribution of the paracellular route was…

Bioaccessibility of calcium, iron and zinc from three legume samples

2004

Legumes can be a source of mineral elements but also of antinutritional factors which can affect their absorption. An in vitro method including gastrointestinal digestion was used to estimate mineral bioavailability. Soluble (bioaccessible) and insoluble calcium, iron and zinc from white beans, chickpeas and lentils were determined after gastrointestinal digestion. The influence of the original sample weight on the soluble mineral fraction was also estimated. The results obtained show that white beans are the legumes with the highest bioaccessible calcium and iron contents. Lentils have a high iron content but its bioaccessibility is much lower than that of iron from white beans and chickpe…

Digestion and absorption rates of [3H]-oleic acid and [14C]-triolein do not differ in rats fed heated (-) and (+) gossypol cottonseed and soybean flo…

1998

This study was conducted to compare in vivo the acute effects of heated (+) and (-) gossypol cottonseed flours with those of soybean flour on lipid digestion and absorption in growing rats. Rats were fed by gastric intubation mixed [ 3 H]-oleic acid and [ 14 C]-triolein with heated flours or without flour (control). Lipid digestion and absorption were determined for 6 h after meal intubation. Both radioactivities recovered in gastrointestinal tract were significantly higher in rats fed (+) gossypol cottonseed flour than in all other groups. The majority of both recovered radioactivities was found in stomach contents, then in stomach wall and finally in intestinal wall. The distribution of b…
