Grandidierella bonnieroides Stephensen, 1948 (Amphipoda, Aoridae)-first record of an established population in the Mediterranean Sea

2016

The first record in the Mediterranean Sea of the invasive aorid amphipod crustacean Grandidierella bonnieroides is presented. A widespread circumtropical species, recorded off the Saudi coast of the Arabian Gulf, the Red Sea and the Suez Canal, it may have been introduced into the Mediterranean through the Suez Canal. This tube-builder species of soft bottoms recently established a population in the polluted Haifa Bay, Israel. Further, this is the first Mediterranean record of the genus.

The Albian (Vraconnian)-Cenomanian boundary at the western Tethyan margins (Central Tunisia and southeastern France).

2008

AbstractThrough the description and interpretation of the position of macro- and microfossils in several sections of the Albian-Cenomanian boundary in SE France and Central Tunisia, a comparison is made between the north and south margins of the Tethyan Ocean by using the occurrences of marker bioevents. For the planktonic foraminifera, the criterions applicable for the accurate determination of Thalmanninella globotruncanoides (Sigal) – the marker species for the base of the Cenomanian stage – are discussed. The species Th. globotruncanoides and the intermediate forms with its ancestor Th. caroni (Ion) are illustrated. For the ammonites, two subjects are new. Firstly, the species Stoliczka…

Zonation by ammonites and foraminifers of the Vraconnian-Turonian interval: A comparison of the Boreal and Tethyan domains (NW Europe / Central Tunis…

2008

International audience; Since the end of the 19th century the interval comprising the uppermost Upper Albian, the Cenomamian, the Turonian and the basal Coniacian has been subdivided, first into ammonite zones, then, beginning in the middle of the 20th century, into zones of planktonic foraminifera. These two groups, one macrofossil, the other microfossil, are particularly effective for bio-chronostratigraphy thanks to their rapid rates of evolution. But differences in the faunal makeup between the Boreal domain (northwestern Europe) and the Tethyan domain (Mediterranean) have for a long time hindered precise correlation of the two domains. Today, in a time interval covering about 16 millio…

Test of isotopic fractionation during liquid-liquid extraction of volatile components from fruits

1995

Fruits constitute a natural source of flavoring molecules. Nevertheless, an isotopic fractionation could be induced by the extraction of volatile molecules from fruits. After the addition of six volatile molecules to Italia grape (hexyl acetate, acetic acid, linalool, butanoic acid, 3-hydroxy-2-methyl-4-pyrone, and methyl cinnamate) and five volatile molecules to Primofiori lemon (hexanal, trans-2-hexenyl acetate, 1-hexanol, trans-2-hexenol, and 4-decanolide) before extraction, it has been established that, for a particular extraction procedure, there is no significant difference between the 13 C enrichments of these molecules before and after extraction. Nothing has been concluded for acet…

Spatial coherence and potential predictability of intraseasonal descriptors of the rainy season in Soudano-Sahelian Africa : application to the pearl…

2010

The aim of this thesis is twofold : (i) fill a lack of knowledge about the spatial coherence and seasonal predictability of the intraseasonal characteristics (ISC) of the soudano-sahelian rainy season. These ISC are the seasonal rainfall amount (S), the daily rainfall frequency > 1 mm (O), the daily rainfall mean intensity (I), the dates of the onset and withdrawal of the rainy season, the mean length of the dry (LDS) and/or wet spells (LWS) ; (ii) document the climate-agriculture relationship over the Niamey area based on the millet crop example.From FRIEND-AOC daily rainfall records (1950-2000) for a 136 stations-network located in Senegal, Mali, Burkina-Faso and Niger, the spatial cohere…

VECCHI E NUOVI GENITORI: MOTIVI DI CONFLITTO E DI NUOVE ALLEANZE

2010

Il saggio prende in esame i temi e i problemi che si creano quando i figli diventano a loro volta (nuovi) genitori e si trovano a gestire coi loro (vecchi) genitori relazioni che assumono nuove caratterizzazioni. V'è al centro la categoria di asse generazionale, idea che consente d'intendere come, nella prospettiva dell'educane, prendersi cura del patto tra le genrazioni - perché esso risulti generativo

The role of goal pursuit in the interaction between psychosocial work environment and occupational well-being

2010

Abstract The relation of the core components of the Effort–Reward Imbalance model (ERI; Siegrist, 1996 ) to goal pursuit was investigated. Goal pursuit was studied through categories of goal contents – competency, progression, well-being, job change, job security, organization, finance, or no work goal – based on the personal work goals of managers ( Hyvonen, Feldt, Salmela-Aro, Kinnunen, & Makikangas, 2009 ). The study focused on the contribution of the ERI components (effort, reward, effort–reward imbalance, OVC) to goal contents, as well as on the mediating and moderating effects of goal contents between the ERI components and occupational well-being (burnout, work engagement) among youn…
