Are Red Lists really useful for plant conservation? The New Red List of the Italian Flora in the perspective of national conservation policies
2013
La nuova Lista Rossa della flora Italiana comprende tutte le "policy" specie italiane e altre specie di nota conservazione e comprende 400 taxa di cui il 65% sono minacciate di estinzione. La Lista Rossa si basa su un enorme data-set georeferenziato utile per gli scopi di conservazione. - The New Red List of the Italian Flora includes all the Italian policy species and other species of known conservation concerns for a total of 400 taxa, 65% of which are threatened with extinction. The Red List is based on a huge georeferenced data-set useful for conservation purposes. -
Le Currency board : les contraintes de financement et d'ajustement de la convertibilité intégrale
2000
The paper scrutinizes the consequences of the adoption of a currency board arrangement (CBA) by some emerging economies during the 1990s. Considering the justifications o f this choice and the different setting-up contexts, it focuses on the implications of a CBA on the financial system and the real economy. A high degree of liquidity of the banking system is required in the absence of a lender-of-last-resort, and the automatic money supply process strictly disciplines the fiscal policy. Monetary stability is restored; but in most o f these economies where capital markets are underdeveloped, CBA's rules make the domestic credit supply dependent on the ability o f the economy to maintain ove…
Transition metal complexes of tetradentate and bidentate Schiff bases as catalysts for ethylene polymerization: Effect of transition metal and cocata…
2009
This article compares catalytic performance of ethylene polymerization in similar polymerization conditions of transition metal complexes having two ligands [O,N] (phenoxy-imine) and having one tetradentate ligand [O,N,N,O] (salphen or salen). It is shown that the activity of both complex types as well as the product properties depend in the same way on the type of central metal in the complex and on the cocatalyst used. Although the type of ligand has some effect on the catalyst activity, yet it does not control the properties of the obtained products. The vanadium and zirconium complexes, irrespective of the cocatalyst used, yield linear polyethylene with high molecular weight (a few hund…

TEMPORAL CHANGES IN RESPIRATORY SYMPTOMS/DISEASES AND ASSOCIATED RISK FACTORS IN REAL LIFE
Background: The prevalence of respiratory diseases increased during last centuries and the rapid rise in the prevalence of such diseases cannot be explained by genetic factors. Analyses on general population samples investigated at interval of some years can permit to better comprehend these increases and the associated risk factors, adding new evidences on this important item taking into account the real life setting. Aims: to assess real life temporal changes in respiratory diseases/symptoms (asthma, allergic rhinitis - AR - and chronic obstructive pulmonary disease - COPD) and associated risk factors in general population samples investigated during a period of 30 years. Methods: a gener…
Città-porto a prova di futuro. Linee guida per l’integrazione di soluzioni basate sulla natura per l’adattamento climatico e la tutela della biodiver…
2023
Quale è il ruolo della pianificazione nel rispondere alle sfide della crisi climatica e della perdita di biodiversità nei contesti urbano-portuali? Il lavoro di ricerca costituisce un avanzamento del dibattito sulla riqualificazione delle aree portuali, contesti storicamente avulsi dalla considerazione di tematiche legate alla preservazione e valorizzazione degli habitat naturali e degli ecosistemi. La tesi desidera mettere al centro della discussione le città porto mediterranee come ecosistemi e come insediamenti urbani multi-specie, come attrici del cambiamento responsabile di fronte alle crisi e non soltanto nodi infrastrutturali strategici per l’economia, la finanza e gli usi militari. …
Information Security Risk Assessments following Cybersecurity Breaches : The Mediating Role of Top Management Attention to Cybersecurity
2023
Information Systems (IS) research on managerial response to cybersecurity breaches has largely focused on externally oriented actions such as customer redressal and crisis response. Within the firm itself, a breach may be a symptom of systematic problems, and a narrow, siloed focus on only fixing immediate issues through technical fixes and controls might preclude other managerial actions to ensure future cybersecurity. Towards this end, Information Security Risk Assessments (ISRA) can help surface other vulnerabilities following a breach. While the role of governance in such exercises is emphasized in standards, it is undertheorized in IS research and lacks empirical evidence. We draw on t…
Finnish L2 proficiency for working life : towards research-based language education and supervision practices
2021
In all Nordic countries, the L2 proficiency needed at work has become a key area in the language education provided for adult immigrants. This paper is part of a series of articles that gives an overview of language policies and research activities in the Nordic countries related to L2 in working life, together with a presentation of novel empirical analyses. Here, the focus is on the Finnish perspective. The aims of this paper are twofold. First, it provides an overall picture of the policies and research findings underlying recent tendencies in Finnish L2 language education in/for working life. After this, the article presents two case studies of clinical supervision practices in health c…
