Aymara Collection of Geraldine Quartararo
2020
The contents of this collection pertain to Aymara, an indigenous language spoken in the Andean Plateau. The data included in this collection were gathered for the purpose of investigating evidentiality. The collection comprises 15 recordings, which have been categorized into three distinct groups. The first group encompasses audio recordings, transcriptions, and corresponding translations of the semi-structured task entitled "Family Problems Pictures." The second group consists of audio recordings, transcriptions, and relative translations of another semi-structured task called the "Pear Story." Lastly, the third group contains audio recordings, transcriptions, and relative translations of …
Strategies for the extension of the shelf life of ready to eat prickly pear fruits
2012
The prickly pear fruit (Opuntia ficus indica L. Miller) belongs to the Cactaceae family. The fruit is a berry, composed by an epicarp and the pulp, which represents the edible portion. At maturation, the epicarp turns yellow, red or white, depending on the cultivar. In Italy, the prickly pear is mainly cultivated in Sicily (90% of the national production). The fruit is very sensitive to low storage temperatures (< 5°C) which cause chilling injuries. The fruits can be successfully commercialized as a ready-to-eat product, peeled and suitably packaged. The main limit to its production is the formation of off-flavours due to different factors, such as the growth of microorganism and the action…
The role of native flower visitors in pollinating Opuntia ficus-indica (L.) Mill., naturalized in Sicily
2011
Abstract The role of insects in pollination and consequently in fruit set and quality was assessed in two commercial orchards of the cactus pear, Opuntia ficus-indica (L.) Mill., in Agrigento Province, Sicily. In 1997, insects visiting flowers were sampled during May–June (the first bloom) and July (the second bloom, induced by the “scozzolatura” practise). More than 50 insect species belonging to 10 orders were collected in May–June, while only five species of Hymenoptera Apoidea were collected in July. The quality of fruits arising from the second bloom showed that Hymenoptera alone were able to guarantee effective pollination. To verify the role of insects in pollination in 1996 (during …
Functional foods and nutraceuticals: a way to improve health, prevent disease, and delay aging. The case of cactus pear.
2007
Cactus pear fruits have recently been the object of scientific research aimed at revealing bioactive components. This short review summarizes results obtained by our group. The two characteristic betalain pigments, betanin and indicaxanthin, appear promising molecules to be considered nutraceutical compounds.
The effect of soil volume on the growth of roots and canopy of Opuntia ficus-indica
2019
The influence of soil volume on root development and canopy growth rates of cactus pear (Opuntia ficus-indica) was studied at Palermo University, Italy, in 2014-2016. In November 2014, 60 1-year-old O. ficus-indica cladodes were planted in pots containing five different soil volumes, 50, 33, 18, 9 or 5 L, in a complete randomized design with three replications. Root dry mass, total number of cladodes and canopy dry mass were measured after 6, 12, 18 and 24 months. The results revealed a significant effect of soil volume and sampling time and their interaction (P<0.01) on root dry mass, total number of cladodes and canopy dry mass. Root dry mass ranged between 23 and 206 g, with the highe…
Continuity correction of pearson’s chi-square test in 2x2 contingency tables: A mini-review on recent development
2022
The Pearson’s chi-square test represents a nonparametric test more used in Biomedicine and Social Sciences, but it introduces an error for 2 x 2 contingency tables, when a discrete probability distribution is approximated with a continuous distribution. The first author to introduce the continuity correction of Pearson’s chi-square test has been Yates F. (1934). Unfortunately, Yates’s correction may tend to overcorrect of p-value, this can implicate an overly conservative result. Therefore many authors have introduced variants Pearson’s chi-square statistic, as alternative continuity correction to Yates’s correction. The goal of this paper is to describe the most recent continuity correctio…
Wine label design as a strategic tool to attract consumers. A marketing study on Sicilian wine positioning
2013
Negli ultimi anni il packaging e stato considerato dalle aziende vinicole uno tra i piu importanti strumenti del marketing. Infatti, grazie all’utilizzazione di immagini e testi, e possibile comunicare chiaramente al mercato messaggi coerenti con i prodotti, con i valori dell’azienda e con i target di consumatori di riferimento. In questo studio si e voluto conoscere quanto le etichette siano importanti per le cantine siciliane nelle scelte di posizionamento dei loro vini. Si e voluta, inoltre, misurare l’influenza che le etichette esercitano sui consumatori, indirizzando ed orientando le preferenze al momento dell’acquisto di un vino, senza tralasciare l’eventuale effetto attrattivo causat…
Parasitoids of Leptoglossus occidentalis Heidemann (Heteroptera: Coreidae) recovered in western North America and first record of its egg parasitoid …
2012
The parasitoid complex of the western conifer seed bug, Leptoglossus occidentalis, was studied in British Columbia and California on Pinus monticola and P. contorta var. latifolia. Three egg-parasitoid species were identified: Gryon pennsylvanicum (Hymenoptera: Platygastridae), Ooencyrtus johnsoni (Hymenoptera: Encyrtidae) and Anastatus pearsalli (Hymenoptera: Eupelmidae). Leptoglossus occidentalis represents a new host record for O. johnsoni, and California is a new distribution record for G. pennsylvanicum. Gryon pennsylvanicum was the dominant species during the entire oviposition period of the bug, reaching peak parasitization levels in July (25%). Ooencyrtus johnsoni and A. pearsalli e…
Seasonal characterization of nutritional and antioxidant properties of Opuntia ficus-indica [(L.) Mill.] mucilage
2021
Abstract Opuntia ficus-indica fruit and cladodes are a source of mucilage, a carbohydrate complex, as well as of phytochemicals and other nutrients, useful in the food industry. Despite the environmental-based composition variability has been studied, there is no information on its seasonal variability, which is particularly important for its industrial use. In this study, some technological, nutritional, and bioactive properties of O. ficus-indica cladodes mucilage were analyzed during the seasonal growth period. Total proteins did not change during the whole period and the lipid content significantly decreased from winter to the onset of summer. The fatty acid profile showed high levels o…
Glochidial infection by the endangered Margaritifera margaritifera (Mollusca) increased survival of salmonid host (Pisces) during experimental Flavob…
2021
AbstractCo-infections are common in host-parasite interactions, but studies about their impact on the virulence of parasites/diseases are still scarce. The present study compared mortality induced by a fatal bacterial pathogen, Flavobacterium columnare between brown trout infected with glochidia from the endangered freshwater pearl mussel, Margaritifera margaritifera, and uninfected control fish during the parasitic period and after the parasitic period (i.e. glochidia detached) in a laboratory experiment. We hypothesised that glochidial infection would increase host susceptibility to and/or pathogenicity of the bacterial infection. We found that the highly virulent strain of F. columnare c…
