Effect of low SO2 postharvest treatment on quality parameters of ‘Italia’ table grape during prolonged cold storage
2018
Table grape is a non-climacteric fruit with a low rate of physiological activity, very sensitive to water loss and fungal infection (Botrytis cinerea) during postharvest handling and cold storage. Gray mold is the most aggressive postharvest disease, because of its ability to develop at low temperatures, for that reason, it is standard practice to fumigate with sulfur dioxide (SO2) immediately after packing. ‘Italia’ table grape boxes were stored at 2°C for 4 months in a storage room with low concentrations of SO2 (0.20%) to extend their postharvest shelf life. Every 15 days, a sample of ‘Italia’ table grapes boxes was moved to 20°C for 3 days for the shelf life simulation. During storage, …
Ethical reconstruction of citizenship: A proposal between the intimate self and the public sphere
2019
ABSTRACTWhen, in societies today, civic commitment decreases, there is a call for the need to strengthen citizenship education, identified uniquely with its public dimension and, on the other hand,...
Exegesis and myths as methodologies of research in tourism
2013
Anthropology has given interesting paradigms to tourism-led research. From the role played by culture to the conflict between host and guest, anthropology has focused in mobility and tourism issues. Nonetheless, when we think in tourism we imagine an all-encompassing institution. There were many forms of tourism, each one enrooted in their own culture. Mythology and exegesis remind not only that other non-western forms of tourism are interesting to study but also how we can examine those cultural values that do not exist any longer. What this note of research sustains is that positivism monopolized in tourism fields some methods at the time pushing others to the periphery of knowledge, like…
Norway-Russia disaster diplomacy for Svalbard
2020
Abstract The Arctic is frequently framed as a region of disaster and conflict, as well as of opportunity and cooperation. Disaster diplomacy is one approach for examining how dealing with disasters might or might not affect conflict and cooperation, yet little work on Arctic disaster diplomacy has been completed, especially regarding specific bilateral relations. This paper contributes to filling in this gap by focusing on the post-USSR era to provide the first examination of the prospects and relevance of Norway-Russia disaster-related interaction for the Svalbard archipelago. As a discussion paper focusing on one case study, Norway-Russia disaster diplomacy is analysed in the context of S…
La cuestión migratoria cubana. Algunas apreciaciones
2017
El trabajo tiene como objetivo introducir al lector en algunas cuestiones de interés en relación a la normativa migratoria cubana, resaltando algunos conceptos de relevancia para los lectores ávidos en la materia y sobre todo en el complejo mundo del derecho cubano sumergido en las indefiniciones. Destacando además la incidencia de esta norma en el ámbito de la persona y la autonomía de la voluntad.
Intraguild interactions between egg parasitoids: window of opportunity and fitness costs for a facultative hyperparasitoid.
2013
We investigated intraguild interactions between two egg parasitoids of Nezara viridula (L.) (Heteroptera: Pentatomidae), Ooencyrtus telenomicida (Vassiliev) (Hymenoptera: Encyrtidae) and Trissolcus basalis (Wollaston) (Hymenoptera: Platygastridae), as the former has the potential to be a facultative hyperparasitoid of the latter. We assessed the suitability of N. viridula eggs for the development of O. telenomicida as a function of egg age when they were unparasitized, or had been attacked by T. basalis at different times prior to exposure to O. telenomicida females. Ooencyrtus telenomicida can exploit healthy N. viridula host eggs up to 5 days of age, just prior to the emergence of N. viri…
Perception of mineral character in Sauvignon blanc wine: inter-individual differences
2014
Revue non indexée dans le JCR.; Of the descriptors employed to characterize wine organoleptically, minerality is arguably one of the most enigmatic. The aim of the work described in this article was to delineate the nature of perceived minerality in Sauvignon wine, specifically its sensorial reality for experienced wine professionals from France and New Zealand. Participants evaluated 16 Sauvignon blanc wines (8 French; 8 New Zealand) under three conditions, ortho-nasal olfaction, palate only (Nose-clip condition), and by full tasting (global perception). Data from the global condition only are reported here. Key results include: i) that although there were quantitative differences in perce…
Intraguild interactions between two egg parasitoids of a true bug in semi-field and field conditions.
2014
International audience; Research on interspecific competitive interactions among insect parasitoids has often been characterized by laboratory studies in which host insects are exposed to female parasitoids of different species in various sequences and combinations. In the last years, an increasing number of studies have investigated interspecific interactions under field and semi-field conditions although just a few number of works focused on egg parasitoids. In this work, we undertook a two-year study to investigate interspecific interactions between Trissolcus basalis (Wollaston) (Hymenoptera: Platygastridae) and Ooencyrtus telenomicida (Vassiliev) (Hymenoptera: Encyrtidae), two egg para…
How Comprehensive School Students Perceive their Psychosocial School Environment
2010
The aim of this study was to describe students’ perceptions of their psychosocial school environment and to examine the associations between such perceptions and students’ perceived school performance. Our analyses were based on data from the Health Behaviour in School‐Aged Children 2006 study, involving responses by Finnish students from grades 7 and 9. The results indicated that students’ perceptions of their school environment were fairly positive, but that a remarkably large proportion of the students reported negative attitudes towards school. School engagement, school strain, and teacher‐student relations were found to be the most influential predictors in the psychosocial school envi…
Students' Perception of School and Their Smoking and Alcohol Use: A Cross-National Study
2000
The objective of the paper is to study how 15 year old students' perceptions of the psychosocial environment in their schools, defined as student autonomy, teacher support, student support and demands, relate to smoking and alcohol use. Data from 15 year old students in Finland and Norway are included (n=2.816), using structural equation modelling to test theoretical models. The best model fitting the data shows that low student autonomy, low teacher support, student support and inadequate demands are significantly associated with health compromising behaviours directly, and indirectly through students' satisfaction with school. Low student autonomy is the strongest predictor of the four. T…
