Disciplinary Versus Institutional Approaches, Higher Education
2020
Institutional perspectives focus on HEIs as organisations and disciplinary perspectives focus on HEIs as cultural entities. This entry discusses the strengths and weaknesses of cultural and institutional approaches to higher education and higher education research. peerReviewed
Low levels of both xanthine dehydrogenase and of cellular retinol binding protein are responsible for retinoic acid deficiency in malignant human mam…
2009
The seeming impairment of retinoid metabolism in human breast tumor cells has been attributed to the lower expression of cellular retinol binding proteins (CRBPs), of alcohol/retinol dehydrogenases, or aldehyde/retinaldehyde dehydrogenases. In a previous study we indicated that xanthine dehydrogenase (XDH) is able to oxidize actively both all-trans-retinol (t-ROL) bound to the CRBP (holo-CRBP) and all-trans-retinaldehyde (t-RAL) to all-trans-retinoic acid (t-RA) in human mammary epithelial cells (HMEC). Since both XDH and CRBP are required for the biosynthesis of t-RA, we have inspected their bioavailability in both estrogen-responsive and nonresponsive human mammary epithelial cancer cells…
Orientare dal liceo all’università: il progetto di ricerca-formazione «FOrP»
2019
In questo contributo, dopo avere chiarito la finalità dell’orientamento presentata nelle Linee guida nazionali per l’orientamento permanente(MIUR, 2014) e descritto brevemente alcune metodologie educative utilizzate in Italia negli ultimi venti anni per aiutare gli studenti a costruire il loro progetto di vita professionale, si presenta nelle linee generali il progetto di ricerca-formazione «FOrP» (Formazione, Orientamento, Progettualità), volto a colmare, mediante laboratori-ponte di carattere disciplinare scuola-università, il gap tra le competenze disciplinari acquisite dagli alunni alla fine del percorso degli studi liceali e quelle richieste all’inizio degli studi universitari, nonché …
Development of high-performance thin layer chromatography method for identification of phenolic compounds and quantification of rosmarinic acid conte…
2020
ABSTRACT Aim: Representatives of Nepetoideae Burnett subfamily are promising species of the Lamiaceae Martinov family because of accumulating such valuable groups of secondary metabolites as terpenoids and polyphenols. A high-performance thin layer chromatography (HPTLC) fingerprint method for the qualitative determination of phenolic compounds and for the quantification of rosmarinic acid (RA) content in methanol extracts of five species of this subfamily was developed for the first time. Materials and Methods: Dried aerial parts of Dracocephalum moldavica L., Ocimum americanum L., Lophanthus anisatus (Nutt.) Benth., Monarda fistulosa L., and Satureja hortensis L. collected in flowering pe…
Total Absorption Spectroscopy of Fission Fragments Relevant for Reactor Antineutrino Spectra and Decay Heat Calculations
2016
Beta decay of fission products is at the origin of decay heat and antineutrino emission in nuclear reactors. Decay heat represents about 7% of the reactor power during operation and strongly impacts reactor safety. Reactor antineutrino detection is used in several fundamental neutrino physics experiments and it can also be used for reactor monitoring and non-proliferation purposes. 92,93Rb are two fission products of importance in reactor antineutrino spectra and decay heat, but their β-decay properties are not well known. New measurements of 92,93Rb β-decay properties have been performed at the IGISOL facility (Jyväskylä, Finland) using Total Absorption Spectroscopy (TAS). TAS is complemen…

Safety Culture and Safety Performance in High-Reliability Organizations: A Synthesis of IDOCAL’S Contributions to the Literature
2020
Improving safety culture and safety performance is a constant concern for companies operating in high-risk environments. For almost two decades, IDOCAL (the Research Institute of Personnel Psychology, Organizational Development and Quality of Working Life) has been contributing to advancing our understanding of these important concepts through theoretical development and empirical research. The objective of this article is to synthesize these contributions. Some of the most prominent are (1) the development of a framework for the evaluation of safety culture and its correlates based on the AMIGO model, (2) the establishment of the empowering leadership model as a valuable concept in safety …
Immunogenicity and safety of a quadrivalent high-dose inactivated influenza vaccine compared with a standard-dose quadrivalent influenza vaccine in h…
2021
A quadrivalent high-dose inactivated influenza vaccine (IIV4-HD) is licensed for adults ≥65 y of age based on immunogenicity and efficacy studies. However, IIV4-HD has not been evaluated in adults aged 60–64 y. This study compared immunogenicity and safety of IIV4-HD with a standard-dose quadrivalent influenza vaccine (IIV4-SD) in adults aged ≥60 y. This Phase III, randomized, modified double-blind, active-controlled study enrolled 1,528 participants aged ≥60 y, randomized 1:1 to a single injection of IIV4-HD or IIV4-SD. Hemagglutination inhibition (HAI) geometric mean titers (GMTs) were measured at baseline and D 28 and seroconversion assessed. Safety was described for 180 d after vaccinat…
Positron production using a 9 MeV electron linac for the GBAR experiment
2020
For the GBAR (Gravitational Behaviour of Antihydrogen at Rest) experiment at CERN's Antiproton Decelerator (AD) facility we have constructed a source of slow positrons, which uses a low-energy electron linear accelerator (linac). The driver linac produces electrons of 9 MeV kinetic energy that create positrons from bremsstrahlung-induced pair production. Staying below 10 MeV ensures no persistent radioactive activation in the target zone and that the radiation level outside the biological shield is safe for public access. An annealed tungsten-mesh assembly placed directly behind the target acts as a positron moderator. The system produces $5\times10^7$ slow positrons per second, a performan…
