Stoïlow’s theorem revisited
2020
Stoilow's theorem from 1928 states that a continuous, open, and light map between surfaces is a discrete map with a discrete branch set. This result implies that such maps between orientable surfaces are locally modeled by power maps z -> z(k) and admit a holomorphic factorization. The purpose of this expository article is to give a proof of this classical theorem having readers in mind that are interested in continuous, open and discrete maps. (C) 2019 Elsevier GmbH.

La copertura dei siti archeologici: questioni di protezione e comunicazione delle rovine
2013
Le recenti istanze di presentazione dell’archeologia, hanno portato alla realizzazione di una casistica d’interventi di copertura e musealizzazione delle rovine assai varia, la quale costituisce una base sostanziale per lo sviluppo di nuove azioni conservative, tutte legittime e tutte praticabili a secondo dei vari episodi archeologici. Talvolta la musealizzazione di alcuni siti archeologici ha addirittura costituito una vera e propria “conservazione preventiva”, dalla quale sono derivate azioni ancor più mirate. Il programma d’interventi che consegue alla decisione di mettre en valeur qualsiasi resto dell’antichità non può che costituirsi dall’apporto degli strumenti forniti non soltanto d…
Interactive Effects of Genotype and Molybdenum Supply on Yield and Overall Fruit Quality of Tomato
2019
Molybdenum (Mo) is an essential trace element for plant growth, development, and production. However, there is little known about the function and effects of molybdenum in tomato plants. The present study assessed the influences of different Mo concentrations on four tomato F1 hybrids (“Bybal” F1, “Tyty” F1, “Paride” F1, and “Ornela” F1) grown using a soilless system with different Mo levels [0.0, 0.5 (standard NS), 2.0, and 4.0 μmol L−1, respectively]. The crop yield, plant vigor, fruit skin color, TA, fruit water content as well as the accumulation of SSC, and some antioxidant compounds such as lycopene, polyphenols and ascorbic acid were evaluated. The minerals concentration, including n…
Crystal structure of chlorido(2-{1-[2-(4-chlorophenyl)hydrazin-1-ylidene-κN]ethyl}pyridine-κN)(η5-pentamethylcyclopentadienyl)rhodium(III) chloride
2015
The title compound, [Rh(η5-C5Me5)Cl(C13H12ClN3)]Cl, is chiral at the metal and crystallizes as a racemate. Upon coordination, the hydrazinylidenepyridine ligand is non-planar, an angle of 54.42 (7)° being observed between the pyridine ring and the aromatic ring of the [2-(4-chlorophenyl)hydrazin-1-ylidene]ethyl group.

The title compound, [Ir(η5-C5Me5)Cl(C18H14ClN3)]B(C6H5)4, is chiral at the metal center and crystallizes as a racemate. In the cation, the hydrazinylidenepyridine ligand isN,N-coordinated through theN-pyridyl andN-hydrazinylidene groups forming a five-membered metallacycle. An intramolecular C—H...Cl hydrogen bond is observed. In the crystal, centrosymmetrically-related cations are connected by C—Cl...π interactions, forming a dimeric structure. The crystal packing is further stabilized by weak interionic C—H...π interactions.
Universal Patterns in Color-Emotion Associations Are Further Shaped by Linguistic and Geographic Proximity
2020
Many of us “see red,” “feel blue,” or “turn green with envy.” Are such color-emotion associations fundamental to our shared cognitive architecture, or are they cultural creations learned through our languages and traditions? To answer these questions, we tested emotional associations of colors in 4,598 participants from 30 nations speaking 22 native languages. Participants associated 20 emotion concepts with 12 color terms. Pattern-similarity analyses revealed universal color-emotion associations (average similarity coefficient r = .88). However, local differences were also apparent. A machine-learning algorithm revealed that nation predicted color-emotion associations above and beyond tho…
Measurement of Open Access as an Infrastructural Challenge : The Case of Finland
2017
Finland has set numeric goals for the development of open access. However, at the moment, no system is available by which this development could be monitored. Poor quality in the metadata records in universities’ research information databases prevents metadata-based analysis of open access publishing progress. This paper shows how the quality problems of Finnish publication data can be resolved through centralizing the services and processes of metadata creation and by improving the interoperability of systems involved in the processes. As a result, this study describes an environment where reliable measurement of open access is possible and presents suggested actions for improving the Fin…
Developing and Validating a Behavioural Model of Cyberinsurance Adoption
2021
Business disruption from cyberattacks is a growing concern, yet cyberinsurance uptake remains low. Using an online behavioural economics experiment with 4800 participants across four EU countries, this study tests a predictive model of cyberinsurance adoption, incorporating elements of Protection Motivation Theory (PMT) and the Theory of Planned Behaviour (TPB) as well as factors in relation to risk propensity and price. During the experiment, participants were given the opportunity to purchase different cybersecurity measures and cyberinsurance products before performing an online task. Participants likelihood of suffering a cyberattack was dependent upon their adoption of cybersecurity me…
