Combining the Retrospective Interviews of Wave 3 and Wave 7: The Third Release of the SHARE Job Episodes Panel
No full textData about working life histories, migration histories, fertility histories and marriage/cohabitation histories collected in the third wave of the SHARE survey were organised into a retrospective panel as described in Brugiavini, Cavapozzi, Pasini, and Trevisan (2013) and Antonova, Aranda, Pasini, and Trevisan (2014). In wave 7 respondents from the new countries were included in the survey and refresher sample respondents from the “old” countries were administered the retrospective questionnaire for the first time. We now combine all the life histories into a single panel dataset and add a new variable reporting the working/non-working condition each year

Gathering of Robots in a Grid with Mobile Faults
No full textThe gathering of two or more agents in a graph is an important problem in the area of distributed computing and has been extensively studied especially for the fault free scenario. In this paper we consider the mobile agents gathering problem in the presence of an adversarial malicious agent which by occupying an empty node might prevent honest agents from entering this node. The honest agents move in synchronous rounds and at each round an agent can move to an adjacent node only if this node is not occupied by the malicious agent. We model the honest agents as identical finite state automata moving in an anonymous oriented grid topology and having no information about the size of the graph, while the malicious agent is assumed to be arbitrarily fast and to have full knowledge of the locations and the strategy of the honest agents at all times. The agents cannot leave messages at nodes or communicate with each-other unless they meet at a node. Previous studies consider the problem for ring networks and
for asynchronous grids, where rendezvous was solved only for the special case of agents starting already in connected configurations. In this paper, we study the problem for synchronous agents in anonymous oriented grid networks for any starting configuration without multiplicities and any number of agents. We first show that rendezvous is impossible for 2 agents even when the agents can see the locations of each-other at all times, while 3 agents can gather if they have global visibility. We then present a universal deterministic algorithm that solves the problem for 4 or more agents having only local visibility and constant memory, in any oriented grid with a malicious mobile adversary

No full textCalcium ethoxide nanosuspension, a consolidating product developed during the European
Nanomatch project, is here modified by adding two different solvents, 2-butanol and n-butylacetate,
chosen for their different boiling points with respect to ethanol, the solvent employed in a previous
work to dilute the original product. Fourier transform infrared spectroscopy (µFT-IR) was used to
understand how the presence of these new solvents can influence the kinetics of the carbonation
process and the pathway reaction. Furthermore, coatings derived from nanosuspensions were
maintained for specific time intervals at controlled relative humidity conditions (RH = 50% and
RH = 90%); the formed mineralogical phases were characterized by µFT-IR and X-ray diffraction
(XRD). Results indicate that the used solvents can influence the kinetic and reaction pathways,
while the phases formed at the end of the carbonation process are influenced by both solvents
and RH conditions. The effectiveness of calcium ethoxide based product diluted in 2-butanol and
n-butylacetate as limestone consolidants was evaluated with drilling resistance measurement system
(DRMS) and ultrasound pulse velocity (UPV). The impact on color coordinates was also assessed.
The results were compared with those obtained with the same product diluted in ethanol and a
commercial nanolime. The use of these solvents gave different and better results in terms of efficac
The Late Latin Literary Epigram (Third to Fifth Centuries CE)
No full textThis chapter focuses on the late antique Latin epigrams of secular inspiration composed between the third and fifth century ce. It examines the repertoire and authors that have reached us (Carmina XII sapientum, Ausonius, Epigrammata Bobiensia, Claudian, Sidonius Apollinaris, Ennodius) and illustrates the modes of circulation of epigrams, including the use of collections and different literary contexts
