Analytical comparison and sensory representativity of SAFE, SPME, and Purge and Trap extracts of volatile compounds from pea flour
2012
Pisum sativum is of great economic and nutritional interest due to its protein content. Nevertheless, pea products are underused as a protein source in human food because of their strong beany flavour. Therefore, the objective of this study was to select an efficient and representative method to extract volatile molecules of pea flour. In the first step, three extraction methods were chosen: solid phase micro extraction (SPME); Purge and Trap extraction and solvent assisted flavour evaporation (SAFE). The corresponding extracts were analysed by gas chromatography coupled with mass spectrometry. In the second step, the sensory representativity of the extracts was assessed either by direct ga…
The overstated generational gap in online news use? A consolidated infrastructural perspective
2021
Recent research by Taneja et al. suggested that digital infrastructures diminish the generational gap in news use by counteracting preference structures. We expand on this seminal work by arguing that an infrastructural perspective requires overcoming limitations of highly aggregated web tracking data used in prior research. We analyze the individual browsing histories of two representative samples of German Internet users collected in 2012 ( N = 2970) and 2018 ( N = 2045) and find robust evidence for a smaller generational gap in online news use than commonly assumed. While short news website visits mostly demonstrated infrastructural factors, longer news use episodes were shaped more by …
La funzione anticoncorrenziale della contrattazione collettiva nazionale di categoria. Nodi critici e prospettive
2021
Diversi fattori concorrano a destabilizzare la funzione anticoncorrenziale della contrattazione collettiva. Tra questi, la segmentazione delle categorie e la frammentazione delle rappresentanze hanno contribuito alla proliferazione dei contratti disponibili, divenuti oggetto di una vera e propria competizione al ribasso. Il piano su cui la crisi della funzione antidumping della contrattazione appare più immediatamente tangibile è quello salariale, acuendo, piuttosto che arginando, l’ormai dilagante fenomeno di impoverimento del lavoro. Il saggio, dopo l’analisi di tali aspetti, si sofferma sulle opzioni de iure condendo e sul loro contributo in un’ottica di riconquista della tradizionale au…
