Rappresentazioni della Sicilia. Un'indagine quali-quantitativa
2010
Qual è la rappresentazione della Sicilia costruita dai organi di stampa? Qual è la cornice che fa da sfondo ai discorsi sulla Sicilia? Come si rappresenta l'isola chi vi si reca per ragioni di svago? Cosa racconterà al termine del soggiorno? Il libro tenta di dare una risposta a questi interrogativi, presentando e confrontando i risultati dell'analisi testuale di articoli giornalistici che hanno riguardato la Sicilia e delle risposte a interviste rivolte a turisti in visita nella regione. Dall'analisi dei testi raccolti si desumono, inoltre, aspetti legati alla cultura civica, facendo emergere anche la necessità di diffondere buone pratiche. La percezione di vivere in una regione ricca di f…

Multispēlētāju un individuālo spēļu dalībnieku afekta atšķirības
2018
Pētījuma mērķis bija noskaidrot, vai multispēlētāju grupas dalībniekiem pozitīvā afekta rādītāji būs augstāki, bet negatīvā afekta rādītāji zemāki nekā individuālā režīma spēļu dalībniekiem. Šī pētījuma ietvaros tika pārbaudīti līdzīgu pētījuma rezultāti. Afekta novērtējumam tika izvēlēta I-PANAS-SF aptauja, kas novērtē indivīdu afektīvos stāvokļus gan interperosnālā, gan intrapersonālā līmenī. Pētījuma izlasi pārstāvēja nejauši izvēlēti 86 respondenti, vecumā no 18 līdz 28 gadu vecumam. Izvirzītā hipotēze apstiprinājās daļēji, jo galvenajās skalās, kas ir pozitīvais un negatīvais afekts, nebija statistiski nozīmīgas atšķirības. Savukārt ieinteresētības un aktivitātes skalās tika pamanītas …
Latvijas Nacionālā mākslas muzeja izstāžu atklāšanas interakcijas rituāls
2018
Maģistra darbā “Latvijas Nacionālā mākslas muzeja izstāžu atklāšanas interakcijas rituāls” analizēta Latvijas Nacionālā mākslas muzeja izstāžu atklāšanas rituāla prakse, īpašu uzmanību pievēršot indivīdu pieredzes apmaiņai un nozīmju interpretācijai sociālās mijiedarbības kontekstā. Darba teorētisko bāzi veido simboliskā interakcionisma teorētiskā pieeja, kā arī tiek aplūkoti identitātes, simbola un rituāla jēdzieni un to komunikatīvā daba. Maģistra darba empīriskās daļas izstrādei, ar etnogrāfiskās pieejas palīdzību veikti novērojumi izstāžu “Nākotnes valsts”, “Nebeidzamā ainava”, “Jūgendstils. Sākotne. Ietekmes. Savdabība” atklāšanās, kā arī intervijas ar izstāžu atklāšanu rituālu dalībni…
I soffitti lignei dipinti e le strutture di copertura nella architettura religiosa della Sicilia barocca. Conoscenza e diagnosi per il progetto di re…
2009
Wooden ceilings characterize many baroque churches in Sicily and they have a particular meaning in the spatial conception of the architecture because of the false dome prospective painted on. For such a reason they are able to dominate the baroque architectural spatiality being a planar surface. Often forgotten and difficult to reach, the wooden painted ceilings represent an meaningful testimony of history and art but they are know asking for a conservation and maintenance attitude to start. The essay explain a method to design a conservation project without scaffolding and presents the software processing phases to develop in order to point out the degradation conditions through thermograp…
Shifting Long-Term Tillage to Geotextile Mulching for Weed Control Improves Soil Quality and Yield of Orange Orchards
2023
Weed control in urban and peri-urban orange orchards is challenging due to operational and legislative restrictions. Tillage, besides from negatively affecting soil fertility and microorganisms, is demanding for humans. On the other hand, herbicides are advised against due to the possibility to reach waterbodies from the soil surface. Therefore, in urban and peri-urban areas, instead of tillage and herbicides, mulching with black plastic geotextile fabric is often used. This study aimed at assessing the impact of long-term soil mulching with black plastic geotextile fabric on soil fertility, microbial community and yield of an orange orchard in comparison to conventional tillage. To this ai…
The Utility of Ground Bryophytes in the Assessment of Soil Condition in Heavy Metal-Polluted Grasslands
2022
Bryophytes are commonly used in biomonitoring heavy metal pollution, whereas the bioindicative value of bryophyte communities is a less known issue. The aim of the present study is to recognize the utility of the bryophyte community’s structure in the assessment of soil condition in heavy metal-polluted, dry grasslands. The study plots are examined with respect to bryophytes; vascular plants; concentrations of Zn, Pb, Cd, and As in the soil; total nitrogen and organic carbon content in the soil; and soil pH. The results show that both bryophyte species richness and composition greatly depend on soil chemical characteristics, including heavy-metal pollution levels and soil pH. Three groups o…
SHORT-TERM RESPONSE OF SOIL MICROORGANISMS TO ESSENTIAL OILS WITH ALLELOPATHIC POTENTIAL EXTRACTED FROM MEDITERRANEAN PLANTS
2015
Essential oils (EOs) with allelopathic compounds have been used to reduce or avoid weed germination and growth. The aim of this study was to evaluate the potential phytotoxic effects of EOs extracted from different Mediterranean plants on soil microbial biomass and activity. EOs were extracted from leaves of Eucalyptus camaldulensis Dehnh (EUC); Eriocephalus africanus L. (ERI); Thymus capitatus (L.) Hoffmanns. & Link (TCP); Citrus reticulata Blanco var. ‘Clemenules’ (TAN) and Citrus limon (L.) Osbeck var. ‘Eureka’ (LEM). Each EO was supplied to pots containing 560 g of soil at three different doses (low, medium, high). After 15, 30, 90, 120 days the supply of EOs, soils were destructively a…
A simple field method to measure the hydrodynamic properties of soil surface crust
2013
The hydraulic resistance of the surface crust was determined by a combination of two infiltrometric techniques: first, a surface measurement of steady-state infiltration rate is conducted by a mini-disk tension infiltrometer (MDI); then, the surface crust is removed, its thickness is measured, and a ponded infiltration test is performed at the same site. The Beerkan Estimation of Soil Transfer parameters (BEST) method is applied to estimate the hydraulic properties of the underlying soil provided the particlesize distribution and the bulk density are known. Under the assumption of a unit gradient of hydraulic head below the soil crust, the pressure head at the interface crust-soil is derive…
At the interface between sensation and emotion : perceived qualities of single chords
2017
The focus of this dissertation is to investigate the perception of single chords, both in terms of perceived emotions and psychoacoustic qualities. Previous empirical research on harmony perception has mainly been concerned with horizontal aspects of harmony: studies focusing on vertical harmony perception have been rare. The current work aims to fill some of the still evident gaps between musicology, music psychology, and psychoacoustics with regard to single chord perception by combining both empirical and theoretical approaches. The work comprises three publications, based on two large-scale empirical experiments conducted with the aim of drawing the attention of both expert and inexpert…
