Bretton Woods uudella vuosituhannella : kehityspolitiikka uusliberaalin käänteen jälkeen
2010
Maailmanpankki on ehkä merkittävin kehitysyhteistyön määrittelijä ja yhdessä toisen Bretton Woods -instituution, Kansainvälisen valuuttajärjestön IMF:n kanssa huomattava tekijä globaalissa talousjärjestelmässä. Instituutiot myöntävät talouspoliittisesti ehdollistettuja lainoja kehitysmaille, jotta ne pystyisivät kohentamaan elinolojaan sekä turvaamaan talouskasvun ja sitä myötä vähentämään köyhyyttä. Tutkimuksessani käyn läpi Bretton Woods- instituutioiden, etenkin Maailmanpankin, tapaa vähentää köyhyyttä kehitysmaissa. Tarkastelen, millaiseen ajatusmaailmaan sen voidaan katsoa perustuvan ja miten nykyinen, uusliberaali kehityspolitiikkaa on muotoutunut. Yksinkertaisin kysymys on, pystyykö …
The muqarnas ceiling of the Palatina Chapel in Palermo
2018
St. Peter’s Basilica inside the Royal Palace of Palermo, known as the Palatina Chapel, is one of the most popular medieval monuments in Sicily. Built between 1130 and 1163, it contains interesting wooden framings that represent both bearing and finishing structures. Studies about the Arab-Norman church have often concentrated on the very rich and suggestive decorative mosaic apparatus of walls and floorings, as well as the pictorial cycle of wooden ceilings. Knowledge about the constructive techniques adopted and, in particular, about the realization of the coverings, is very limited: there are wooden floors built at different levels, vaults and wooden ceilings and among these is the portio…

Species richness of polypores can be increased by supplementing dead wood resource into a boreal forest landscape
2019
1. To prevent local species extinction and to counteract population declines, we must ensure species have access to resources they require for life. This can be done through ecological restoration where previously depleted resources are reintroduced. If the restoration is conducted as a one-off action in a large area, it resembles a natural resource pulse, which should lead to increased abundance of individuals, accompanied possibly by increased species richness. Species–energy relationship and underlying theory enable predictions about how different features of resource pulses affect species richness. 2. We conducted a large-scale, controlled, randomized and replicated field experiment to …
The International Monetary System in the Context of the Actual Financial Crisis. Change Proposals
2013
The International Monetary System (I.M.S.) has a crucial role in economy, representing the frame for a sustainable development of the economic relationships between states, while contributing at the progress of the world’s economies. Nowadays, this system confronts large difficulties, as a consequence of the lack of financial disciplinary instruments, meant at regulation and coordination. The actual economic-financial crisis proved the limits of the present I.M.S., reason why it is now under “reconstruction”. In this direction, there is a series of reforms that can be implemented, so that the new architecture of the system is much more solid.
Characterisation of the microflora contaminating the wooden vats used for traditional Sicilian cheese production
2015
Traditional Sicilian cheese productions are carried out employing traditional wooden vats, called <em>tina.</em> Many studies have highlighted the beneficial role of wooden dairy equipment by contributing to enriching the milk microflora and improving the acidification processes. The present work was undertaken to evaluate the safety of the wooden vats used to coagulate milk. To this purpose, the different microbial populations hosted onto the internal surfaces of the vats used to produce two different stretched cheeses, namely <em>Caciocavallo Palermitano</em> and <em>Vastedda della valle del Belìce DOP</em>, were investigated for the presence of spoilag…
X-ray Fluorescence Spectroscopy applied to the study of three sicilian painted artworks
2009
This paper reports on three X-Ray Fluorescence (XRF) studies of ancient Sicilian painted materials: a 13th century canvas from Cerami (Enna, Italy), the Muqarnas wood ceiling of the 12th century Palatine Chapel (Palermo, Italy) and a delicate early 20th century viola d’amore, the property of the Conservatorio di Musica “Vincenzo Bellini” in Palermo. Information about the pigments and preparation layer mixtures used as well as inferences regarding various past painting techniques emerged from the interpretation of spectra and data analyses.
National high-resolution conservation prioritisation of boreal forests
2023
The continuous decline of forest biodiversity highlights the importance of the development of cost-effective and ecologically sustainable land-use planning approaches. Spatial conservation prioritisation (SCP) can be regarded as a useful tool for this challenge. We produced high-resolution, national scale SCP analyses to identify unprotected forest areas that host valuable forest biodiversity. We used stand-based modelled dead wood potential (DWP) data as a primary surrogate for conservation value. In addition, data on forestry operations that have negative impacts on biodiversity, connectivity between forest areas, the observations of red-listed forest species, connectivity to forest habit…
Costruire lo spazio. Il cantiere gotico, dal disegno all'esecuzione.
2016
In ogni momento storico il cantiere edile ha rappresentato una sfida, il locus concreto della realizzazione di ambiziosi progetti, innovative sperimentazioni ed evolutive idee, che hanno permesso di imprimere una svolta decisiva al progresso tecnologico. Complessa e variegata appare la condizione del cantiere siciliano, spesso influenzato da innumerevoli apporti derivanti da altre aree culturali del bacino del Mediterraneo, vero e proprio crogiuolo di saperi a confronto, materiali e tecniche eterogenei, progettisti e maestranze itineranti. Se da un canto la costruzione gotica annoverava limitate conoscenze e metodi elementari in materia resistenza dei materiali, composizione delle forze, me…
Challenges in the use of Near Infrared Spectroscopy for improving wood quality: A review
2018
Aims of study: Forestry-related companies require quality monitoring methods capable to pass a large number of samples. This review paper is dealing with the utilization of near infrared (NIR) technique for wood analysis.Area of study: We have a global point of view for NIR applications and characterization of different kind of wood species is considered.Material and methods: NIR spectroscopy is a fast, non-destructive technique, applicable to any biological material, demanding little or no sample preparation. NIR spectroscopy and multivariate analysis serve well in laboratories where the conditions are controlled. The main challenges to NIR spectroscopy technique in field conditions are mo…
