Bioturbation experiments in the Venice Lagoon

Short experiments (14–21 days) were carried out during autumn 1998 and spring 1999 at one selected site of the Venice Lagoon to measure bioturbation activities and mixing rates, as well as to obtain quantitative information on benthos functionality. Fluorescent sediment particles (luminophores, 63–350 μm) were introduced as pulse inputs at the sediment surface. The concentration–depth profiles of the tracer were simulated with a new advection– diffusion–non local model applied under non-steady state conditions. This allowed the quantification of the mixing parameters associated with different mechanisms: biodiffusion (Db), bioadvection (W) and non-local mixing (Ke,z1, z2). A parameter RS (removed sediment) was also calculated to account for the flux of sediment due to nonlocal transport. Results show that bioturbation was dominated by biodiffusion in autumn and by bioadvection in spring. Mean mixing parameters Db, W, and RS changed from 3.09 to 0.87 cm2 y−1, from 0.93 to 15.50 y−1 and from 5.85 to 7.79 g cm−2 y−1, respectively

Social vs. Risk Preferences under the Veil of Ignorance

This paper reports experimental evidence from a series of a simple Dictator Games in which, randomly matched in pair, subjects choose repeatedly one out of four alternatives involving a pair of fixed monetary prizes, one for them and the other for an anonymously matched subject. While in some treatments player position (i.e. the identity of the best paid agent) is known in advance before subjects have to select their favorite option, in one treatment subjects choose under “the veil of ignorance”, only knowing that either role is equally likely. Finally, we also collect evidence from another treatment, in which the same options correponds to binary lotteries, in which subjects may win one prize or the other with equal probability.This paper reports experimental evidence from a series of a simple Dictator Games in which, randomly matched in pair, subjects choose repeatedly one out of four alternatives involving a pair of fixed monetary prizes, one for them and the other for an anonymously matched subject.

Social vs. risk preferences under the veil of ignorance

This paper reports experimental evidence from a Dictator Game experiment in which subjects choose repeatedly one out of four options involving a pair of fixed monetary prizes, one for them, one for another anonymously matched subject. In some sessions, player position (i.e. the identity of the best paid agent, constant across all options) is known in advance before subjects have to make their decision; in other sessions subjects choose “under the veil of ignorance”, not knowing to which player position they will be eventually assigned. We also collect evidence from additional sessions in which the same options correspond to binary lotteries, in which subjects may win the high or the low prize, but their decisions do not affect other participants. We frame subjects’ decisions within the realm of a simple mean-variance utility maximization problem, where the parameter associated to the variance is interpreted, depending on the treatment conditions, as a measure of pure risk aversion, pure inequality aversion, or some combination of the two. We also condition our estimates to subjects’ individual socio-demographic characteristics.Keywords: dictator games, social preferences, risk preferences, functional identification.

Distribution of the genus Sternbergia Waldst. & Kit. (Amaryllidaceae) in Tuscany (central Italy)

The authors report an updated distribution of the genus Sternbergia Waldst. & Kit. (Amaryllidaceae) in Tuscany by the analysis of herbarium specimens, bibliographic references and records in the field. S. colchiciflora occurs in six localities, four in southern Tuscany and two in northern Tuscany. One out of them, the first in Firenze province, is here recorded. On the contrary, S. lutea is widespread in the region, but the distinction between natural populations and those escaped from cultivation is not always certain. Habitat suitability model at regional level for S. colchiciflora is also reported

Production of radioisotopes within a plasma focus device

In recent years, research conducted in the US and in Italy has demonstrated production of radioisotopes in plasma focus devices, and particularly, on what could be termed "endogenous" production, to wit, production within the plasma it self, as opposed to irradiation of tar gets. This technique relies on the formation of localized small plasma zones characterized by very high densities and fairly high temperatures. The conditions prevailing in these zones lead to high nuclear reaction rates, as pointed out in previous work by several authors. Further investigation of the cross sections involved has proven necessary to model the phenomena involved. In this paper, the present status of research in this field is re viewed, both with regards to cross section models and to experimental production of radio isotopes. Possible out comes and further development are discussed
