Micropropagazione di Thymus capitatus
Thymus capitatus is a compact woody
shrub, endemic to the Mediterranean region, with attractive pink flowers. Although conventional vegetative
propagation of T. capitatus is currently used,
micropropagation could be effective for rapid mass
propagation of selected clones and would preserve
wild plants. Shoot tips of T. capitatus cultured on a
gelled MS medium, supplemented with 0.4 mg l-1 2-iP,
were used as primary explants to establish in vitro culture.
Axillary shoots produced on uncontaminated
explants were excised and subcultured to increase
the stock of shoot cultures. To determine the optimal
medium for shoot multiplication, increasing concentrations
(0, 0.4, 0.8, 1.6 e 3.2 mg l-1) of 2-iP and increasing
concentrations (0, 0.4, 0.8 mg l-1) of IAA were tested
in a factorial experiment. The highest multiplication
rate (8.5 microshoots per explant) was obtained with
the combination of 3.2 mg l-1 2-iP and 0.4 mg l-1 IAA.
Five IAA concentrations (0, 0.4, 0.8, 1.6 e 3.2 mg l-1)
were also tested to determine the optimum conditions
for in vitro rooting of microshoots. A very high rooting
percentage (95%) was achieved. IAA concentrations
equal or higher than 0.8 mg l-1 increased the number
of roots per microcutting. All rooted plantlets were
successfully established in soil

Luci e ombre del diritto penale vivente tra legge e diritto delle Corti
La pubblicazione tratta del diritto penale come interpretato, a livello nazionale, dalla Corte costituzionale e dalla Corte di Cassazione e, a livello sovranazionale, dalle Corti europee (CGCE e CEDU). Uno spazio significativo viene anche dedicato alla trattazione del rapporto tra potere legislativo e potere giudiziario

Relating subjective age to work and non-work outcomes
Taking into consideration subjective age is particularly relevant when examining the motivations of older workers because their interpretation of their age is likely to be at least as important as their chronological age in determining the relative importance of work and non-work aspects of life. Participants were 169 workers who completed a survey on four dimensions of subjective age in relationship with work and non-work outcomes (e.g., retirement intentions, turnover intentions, and orientations toward work, family, and leisure activities). With regard to our dependent variables, we examined: 1) the unique contributions of subjective and chronological ages; 2) the interaction between subjective and chronological ages; and 3) curvilinear relationships of subjective age because past research indicates that linear relationships are insufficient for understanding the roles of such variables. Most of the significant results we obtained concerned the non-linear relationships, specifically they show that subjective age dimensions work in a different way for younger, middle, and older workers. We will discuss the implications for organizational practice and future research on subjective age
