Work values and the transition to work life: A longitudinal study

2015

Abstract Research on career development has shown that work values play a key motivational role in job selection and career development. In the context of the current economic crisis, it is of particular relevance to examine the role of work values for employment in the transition from school to work. This longitudinal study examined the role of intrinsic (perceived importance of having a job that is interesting and matches one's own competences), rewards (having a good salary and high chance for promotion), and security (having a stable job) work values on subsequent employment status and person–job fit (how an individual's job matches one's own characteristics such as education and job pr…

Wykorzystanie zasobów baz danych GIS na potrzeby analizy zróżnicowania obszarów wiejskich w aspekcie działań PROW = Application of GIS databases for …

2018

Realizacja działań w ramach Programu Rozwoju Obszarów Wiejskich (PROW) wymaga obiektywnego rozpoznania potrzeb ich wdrażania, w oparciu o wyniki analiz złożonych procesów przyrodniczych i ekono- miczno-demograficznych zachodzących w czasie i przestrzeni obszarów wiejskich. Wzrastająca funkcjonalność Systemów Informacji Geograficznej (GIS) oraz powszechna dostępność do informacji przestrzennej spowodowały, że bazy danych GIS i analizy geoprzestrzenne stały się skutecznym narzędziem wpierającym implementację działań PROW. Celem pracy jest przedstawienie możliwości wykorzystania danych geoinformacyjnych wybranych baz danych GIS do analizy zróżnicowania przestrzennego obszarów wiejskich wojewód…

Paleoecological insight into the straight-tusked elephant population from the late Middle Pleistocene site of Poggetti Vecchi

Il progetto di ricerca s’incentra sullo studio della macrofauna rinvenuta nel sito paleontologico e archeologico di Poggetti Vecchi, scoperto nella località di Roselle situata in provincia di Grosseto. Nello specifico esso è stato focalizzato sulla ricostruzione paleoambientale e paleoecologica dell’area. L’analisi paleobiologica e tafonomica dei resti faunistici è stata perciò inserita all’interno di un progetto multidisciplinare e l’integrazione di tutti i dati paleontologici (relativi a vertebrati, invertebrati, macroresti vegetali e pollini) con quelli stratigrafici ha permesso di ricostruire dettagliatamente l’evoluzione paleoambientale. Nella seconda parte, lo studio paleoecologico è …

A molecular analysis of some Eastern Atlantic grouper from the Epinephelus and Mycteroperca genus

2005

Abstract Mitochondrial cytochrome b (397 bp) and 16S rDNA (516 bp) sequences analysis was used to investigate the phylogenetic relationships among some Eastern Atlantic Epinephelinae species. Six species of Epinephelus ( E. aeneus , E. caninus , E. costae , E. haifensis , E. marginatus and E. tauvina ) and two species of Mycteroperca ( M. rubra and M. fusca ) were analysed. Neighbour-joining and maximum-parsimony analysis support the paraphyletic grouping of the Epinephelus and Mycteroperca analysed. The maximum pairwise nucleotide divergence value in cyt b among all taxa was 0.196 between E. aeneus and E. marginatus and the minimum value was 0.006 between E. costae and M. rubra . Meanwhile…

Characterization of Colletotrichum strains associated with olive anthracnose in Sicily

2022

Anthracnose caused by Colletotrichum spp. is the most damaging olive fruit disease in many countries, including Italy. This disease has been sporadically detected in Sicily, but new agronomic practices can increase risk of olive anthracnose in this region. An etiological study of the disease focused on local olive cultivars growing at the International Olive Germplasm Collection (IOGC) in Villa Zagaria, Enna, Sicily has been undertaken. During 2018 and 2019, 137 Colletotrichum strains were isolated from olives. Colony morphology, conidium characteristics, and multilocus sequence analyses aided identification of three species: C. acutatum (affecting 70% of symptomatic olives), C. gloeosporio…

Ten millennia of hepatitis B virus evolution

2021

Hepatitis B virus (HBV) has been infecting humans for millennia and remains a global health problem, but its past diversity and dispersal routes are largely unknown. We generated HBV genomic data from 137 Eurasians and Native Americans dated between ~10,500 and ~400 years ago. We date the most recent common ancestor of all HBV lineages to between ~20,000 and 12,000 years ago, with the virus present in European and South American hunter-gatherers during the early Holocene. After the European Neolithic transition, Mesolithic HBV strains were replaced by a lineage likely disseminated by early farmers that prevailed throughout western Eurasia for ~4000 years, declining around the end of the 2nd…

Molecular analysis ofPhytophthoradiversity in nursery-grown ornamental and fruit plants

2015

The genetic diversity of Phytophthora spp. was investigated in potted ornamental and fruit tree species. A metabarcoding approach was used, based on a semi-nested PCR with Phytophthora genus-specific primers targeting the ITS1 region of the rDNA. More than 50 ITS1 sequence types representing at least 15 distinct Phytophthora taxa were detected. Nine had ITS sequences that grouped them in defined taxonomic groups (P. nicotianae, P. citrophthora, P. meadii, P. taxon Pgchlamydo, P. cinnamomi, P. parvispora, P. cambivora, P. niederhauserii and P. lateralis) whereas three phylotypes were associated to two or more taxa (P. citricola taxon E or III; P. pseudosyringae, P. ilicis or P. nemorosa; and…

Identification of Volatile Compounds in Blackcurrant Berries: Differences Among Cultivars

2021

Berries of blackcurrant are known to produce a strong flavor. Some previous studies have reported that a given cultivar of blackcurrant can produce berries with a specific profile of volatile compounds. For the Burgundy region in France, the Noir de Bourgogne cultivar is especially important because it is the main ingredient of a liquor with a designation of origin. The aim of the present study was to characterize the volatile fractions of berries from 15 cultivars in order to explore the possibility of using different cultivars for liquor production. The plants were cultivated under the same conditions and harvested in the same year. The volatile fractions of the harvested berries were ana…

MOLECULAR ANALYSIS OF PHYTOPHTHORA DIVERSITY IN ORNAMENTAL NURSERIES.

2013

A molecular approach based on the use of genus-specific nested-PCR primers (Scibetta et al., 2012; J. Microbiol. Meth. 88: 356-368) was utilized to detect Phytophthora species in soil and root samples of potted ornamentals, collected across Apulia and Calabria, Southern Italy. Analyzed samples comprised many plant species with different levels of symptoms of decline on the canopy and root rots. Extraction protocols were optimized to obtain DNA samples of appropriate quality from soil and roots. The analysis of sequences after cloning of nested-PCR amplicons enabled the identification of different Phytophthora species including P. nicotianae, P. cinnamomi, P. cryptogea, P. palmivora and P. n…
