New technologies can support data collection on endangered shark species in the Mediterranean Sea

2022

In the last 50 yr, shark populations showed steep declines in the Mediterranean Sea. The IUCN lists most Mediterranean species as threatened (55%), while considering 27.5% of them Data Deficient. Here, sharks are currently one of the rarest and more elusive groups of animals, and data from fisheries and scientific monitoring still insufficiently support robust abundance and distribution assessments. New technologies can fill this data gap by linking people and scientists through new monitoring strategies. SharkPulse, an international collaborative project, aims at creating a large world database of shark occurrence records by mining images on the web, social networks, and private archives. …

Tunisian tomato by-products, as a potential source of natural bioactive compounds.

2016

Consumption of tomato and tomato products is positively related to the reduction in cardiovascular disease and several types of cancer, thanks to the presence of natural compounds, such as antioxidants. Peels and seeds fractions of tomato, collected after industrial processing in Tunisian industries, were analysed for nutritional and antioxidants composition in perspective of its utilisation. Proximate composition, fatty acids profile, carotenoids, such as lycopene and beta-carotene, polyphenols contents, demonstrated the good potential of these residual products as a source of natural compounds, useful for food and nutraceuticals applications.

San Luigi: reliquie e reliquiari tra Terrasanta, Francia e Sicilia

2017

Lo studio prende in esame i destini delle reliquie dei visceri del re santo, tra Terrasanta, Sicilia, Tunisi, Francia, dal XIII al XX secolo, e dei loro preziosi contenitori; fra gli oggetti più interessanti figura un'inedita arqueta amatoria catalana in legno e pastiglia dorata con parti metalliche, già policromata, della prima metà del XV secolo, giunta a Monreale verosimilmente tramite un arcivescovo iberico; si passano quindi in rassegna i noti reliquiari secondo la tradizione donati da Filippo IV di Francia alla Chiesa monrealese (della Sacra Spina, secc. XIII-XVII; del Santo Sangue di Cristo, del latte e dei capelli della Madonna, della manna del deserto, ultimo quarto del XIII secolo…

The influence of infective dose, nutrient availability and coinfection on virulence of Flavobacterium columnare : implications of intensive aquacultu…

2016

Ecological factors are known to affect disease dynamics and even lead to disease emergence. Especially in opportunistic, environmentally transmitted pathogens, the environment may significantly contribute to pathogen virulence. Intensive farming, including aquaculture, has been suggested to create conditions favouring development of highly virulent pathogens. At Finnish fish farms, epidemics caused by opportunistic Flavobacterium columnare have been constantly increasing in their prevalence and severity since the 1980’s. Yet, factors behind the increased virulence of the pathogen and their mechanisms of action have largely remained unsolved. In this thesis, I explore the effects of infectio…

Contractual satisfaction: drivers and implication for theory

2014

The aim of inter-firm relations is to achieve each firm’s objectives. The achievement of these objectives is reflected in firms’ satisfaction. Satisfaction as a concept can be studied at different levels and contractual relations is one such level. Most studies on inter-firm satisfaction have looked at the general level of satisfaction, whose drivers are complex to account for. This study aims to investigate contractual satisfaction from the perspective of some of its key drivers. The main finding suggests that, while ongoing term specificity, contingent adaptability, reputation and trust have a positive influence on contractual satisfaction, opportunism has a negative one.

Determination of biological characteristics of Tunisian Artemia salina populations

2012

In this study, Artemia salina cysts collected from four Tunisian hypersaline environments were characterized using biometrical, biological and biochemical descriptors. Biometrical analysis revealed that the mean diameter value ranged from 220.25 to 237.76 μm, for the untreated cysts, from 199 to 224.52 μm for decapsulated cysts and that the chorion thickness ranged from 6.62 to 10.58 μm. 48 h after hatching, Artemia from Sebkha El Meleh, Sebha Moknine, Sfax saltworks and Sahline saltworks presented a hatching percentage of 52.7%, 53.75%, 70.16% and 43.74%, respectively. The length of the freshly hatched instar I nauplii varied from 429 to 449.34 μm. The fatty acids profile showed that the n…

De la standardisation à la normalisation de la gestion médicalisée à l'hôpital : L’apport de la méthode de compensation structurelle et conjoncturelle

1996

Utilization of GHM in budget allocation leads to a reduction of strategic behaviors and restores equity between hospitals. However, heterogeneousness of GHM, with subgroups, is also generating perverse effects. The contractual economical analysis, applied to the statistical modelization of Quantin et al. (1995), underlines how the opportunist behaviors can be reduced. As the PMSI is almost unanimously adopted and considered as an irreversible investment, this approach generates questions on ways to improve the tool. The ultimate goal is to move from standardized costs tonormalized (optimized) costs for maximum efficiency of the tool. Finally, this statistical analysis generates a financial …
