Regularized pseudopotential for mean-field calculations
2019
We present preliminary results obtained with a finite-range two-body pseudopotential complemented with zero-range spin-orbit and density-dependent terms. After discussing the penalty function used to adjust parameters, we discuss predictions for binding energies of spherical nuclei calculated at the mean-field level, and we compare them with those obtained using the standard Gogny D1S finite-range effective interaction.
Multinucleon transfer reactions: an overview of recent results
2012
Large acceptance magnetic spectrometers, such as PRISMA installed at Laboratori Nazionali di Legnaro, gave a further boost to the renewed interest for multinucleon transfer reactions in the last decade. The large solid angles of these devices and the high resolving powers of their detection systems allowed to investigate the transfer process around and well below the Coulomb barrier and to perform nuclear structure studies in several mass regions of the nuclide chart when coupled with large γ-ray arrays such as CLARA. Selected results obtained with the PRISMA-CLARA set-up in odd argon isotopes populated by using the multinucleon transfer process and in sub- barrier transfer measurements are…
‘Then we were ready to be radicals!’ : school student activism in Finnish upper secondary schools in 1960–1967
2021
In the Western countries, Scandinavia and Finland included, the legacy of the student movement of the 1960s has been extensive and established a fixed narrative of a radical movement. This article challenges the elitists and university-centred grand narrative and argues that the student movement was more multifaceted and mobilized young people of various ages and backgrounds. This is done by addressing the international student movement from the perspective of school-aged students in Finnish upper secondary schools, focusing on student activism carried out in school-sanctioned student associations. Above all, this article aims to distinguish the relatively unknown history of the Scandinavia…
Faculty Perception of Inclusion in the University: Concept, Policies and Educational Practices
2021
European universities must face the challenge of diversity and design inclusive practices to address it as part of their social responsibility. However, not all universities are doing the same in terms of diversity practices, so it is important to gather the perceptions of the protagonists. To this end, we have analysed university faculty’s perceptions using a mixed model with a concurrent methodological strategy, including an ad hoc questionnaire validated with 880 educators, as well as 17 semi‐structured interviews. The triangulation of these two instruments allowed us to analyse three key dimensions associated with the idea of attention to diversity in the university: diversity concept o…
Timing of the emergence of the Europe-Sicily bridge (40-17 cal ka BP) and its implications for the spread of modern humans
2014
The submerged sill in the Strait of Messina, which is located today at a minimum depth of 81 m below sea level (bsl), represents the only land connection between Sicily and mainland Italy (and thus Europe) during the last lowstand when the sea level locally stood at about 126 m bsl. Today, the sea crossing to Sicily, although it is less than 4 km at the narrowest point, faces hazardous sea conditions, made famous by the myth of Scylla and Charybdis. Through a multidisciplinary research project, we document the timing and mode of emergence of this land connection during the last 40 kyr. The integrated analysis takes into consideration morphobathymetric and lithological data, and relative sea…
Two-photon laser dynamics.
1995
Degenerate as well as nondegenerate three-level two-photon laser (TPL) models are derived. In the limit of equal cavity losses for both fields, it is shown that the nondegenerate model reduces to the degenerate one. We also demonstrate the isomorphism existing between our degenerate TPL model and that of a dressed-state TPL. All these models contain ac-Stark and population-induced shifts at difference from effective Hamiltonian models. The influence of the parameters that control these shifts on the nonlinear dynamics of a TPL is investigated. In particular, the stability of the periodic orbits that arise at the Hopf bifurcation of the system and the extension of the self-pulsing domains of…
A Contribution to the analysis of the first Spanish public-private partnership in primary and specialized maternity care: a social network analysis a…
2021
The La Ribera University Hospital (Alzira, Valencia) was the first experience of public-private partnership in the Spanish National Health System. In addition to the need to coordinate two levels of health care (primary/specialised), two models of human resource management (public/private) had to be coordinated. To illustrate this complexity, the group of midwives in the health area has been taken, analysing their relational patterns through the methodological approach of Social Network Analysis. In terms of results, out of a population of 31 midwives, those of the public model occupy peripheral positions and cooperate poorly, both internally and externally. However, those of the private mo…
Immigrant Involvement in Voluntary Associations in Europe
2012
This paper measures the impact of immigration on migrants' involvement in associations across Europe. Using multilevel analysis on European Social Survey (ESS) data, we address three questions: Are immigrants likely to become members in voluntary associations? Does this likelihood change with the length of stay in the host country? Does the type of the association make a difference? The findings show that the likelihood of migrants participating in associations increases with the length of stay, while second-generation migrant participation is similar to that of the host society. The relation is stronger for expressive associations and weaker for instrumental-utilitarian ones, while religio…
MANUAL SAMPLING AND TANK SIZE EFFECTS ON THE CALIBRATION CURVE OF PLOT SEDIMENT STORAGE TANKS
2004
In many experimental soil erosion plots, runoff is collected and carried by a conveyance system to a sequence of storage tanks. If the soil loss is measured by collecting, after mixing, samples of the stored suspension, then a calibration curve between the actual mean concentration (C) and the measured concentration (Cm) in the storage tank occurs. The aim of this article was to evaluate experimentally the factors affecting the relationship between C and Cm. For a sandy loam soil, the replicated measurements of Cm (20 samples) for two values of the actual concentration (C = 5 and 25 g/L) showed that the variability of the measurements of Cm is low and confirmed the reliability of a calibrat…
Spatial and temporal patterns of throughfall quantity and quality in a tropical montane forest in Ecuador
2007
Summary In forests, complex canopy processes control the change in volume and chemical composition of rain water. We hypothesize that (i) spatial patterns, (ii) the temporal stability of spatial patterns, and (iii) the temporal course of solute concentrations can be used to explore these processes. The study area at 1950 m above sea level in the south Ecuadorian Andes is far away from anthropogenic emission sources and marine influences. It received ca. 2200 mm of rain annually. We collected rain and throughfall on an event and within-event basis for five precipitation periods between August and October 2005 at up to 25 sites and analyzed the samples for pH and concentrations of K, Na, Ca, …
