Abstract	The aim of the book is to study some aspects of geometric evolutions, such as mean curvature flow and anisotropic mean curvature flow of hypersurfaces. We analyze the origin of such flows and their geometric and variational nature. Some of the most important aspects of mean curvature flow are described, such as the comparison principle and its use in the definition of suitable weak solutions. The anisotropic evolutions, which can be considered as a generalization of mean curvature flow, are studied from the view point of Finsler geometry. Concerning singular perturbations, we discuss the convergence of the Allen-Cahn (or Ginsburg-Landau) type equations to (possibly anisotropic) mean curvature flow before the onset of singularities in the limit problem. We study such kinds of asymptotic problems also in the static case, showing convergence to prescribed curvature-type problems

Series title	CESifo working paper : Category 2: Public Choice ; no. 6772
Abstract	We exploit a unique dataset merging data on individual socio-economic characteristics and political participation in an Italian municipality to investigate the relationship between ethnic diversity in residential neighborhoods and individuals' propensity to vote. We document a sizable negative impact of diversity on overall electoral turnout which reflects differential effects at the individual level, depending on household equivalent income. Specifically, we show that ethnic heterogeneity in the neighborhood reduces the political participation of the poor, while it fosters that of the more affluent. These results highlight a potential democratic deficit stemming from reduced and unequal electoral turnout in increasingly ethnically heterogeneous neighborhoods.

Abstract	Differently from Atkinson and Morelli (2011) who detect no clear link between increases in income inequality and systemic banking crises, we show that a large majority of crises occurred between 1982 and 2008 have been preceded by persistently high levels of income inequality. Such association is robust when considering Gini values for incomes after-tax as well as before-tax and transfers. Moreover, we investigate the pattern of income inequality levels before and after a group of banking crises and the relative levels of income inequality in a large sample of OECD countries that did not experience banking crises between 1980 and 2010.

Abstract	We study the effects of changes in household structure-marriage, divorce, widowhood, and the presence of children of different ages-on individual-level voter turnout. To this end, we assemble a unique voter-level panel dataset spanning four elections in a large Italian municipality. The data merge information from administrative voter rolls, the civil register, and income tax files. Differences-in-differences estimates accounting for voter fixed effects reveal sizable effects of marital status and children on voter participation. Impact estimates are significantly different across genders and are not explained by socio-economic characteristics. To show that changes in voter participation do not predate changes in family structure, we use an event-study approach that is rare in micro-econometric studies of voter turnout. Lastly, we explore possible mechanisms using pooled cross-sectional data from the Italian National Election Studies and the ISTAT Aspects of Daily Life surveys. Our results shed new light on the importance of life-course transitions and their gender-heterogeneous effects as key drivers of voter turnout.

Abstract	Motivated by a variational model concerning the depth of the objects in a picture and the problem of hidden and illusory contours, this book investigates one of the central problems of computer vision: the topological and algorithmic reconstruction of a smooth three dimensional scene starting from the visible part of an apparent contour. The authors focus their attention on the manipulation of apparent contours using a finite set of elementary moves, which correspond to diffeomorphic deformations of three dimensional scenes. A large part of the book is devoted to the algorithmic part, with implementations, experiments, and computed examples. The book is intended also as a user's guide to the software code appcontour, written for the manipulation of apparent contours and their invariants. This book is addressed to theoretical and applied scientists working in the field of mathematical models of image segmentation

Abstract	Breastfeeding is an important aspect of mother-newborn relationship and is of great benefit for the baby. Unfortunately, many drugs taken by the mother may pass into her milk and exert an effect on the newborn. Very limited data is available and a cautionary approach is warranted especially when the woman receives anticancer treatment including chemotherapy , hormonal treatment and the recently introduced target agents as well as monoclonal antibodies. In all these conditions breastfeeding should be put on hold.More and more often physicians are faced with women that are pregnant years after the diagnosis of cancer: this has long been considered dangerous for the mother, but data show that prognosis is definitely not worse. If the woman is no longer being actively treated, breastfeeding is advisable every time it is possible, even if patients that received breast radiation may be unable to produce a sufficient amount of milk on that side.

Abstract	We identify the degree of intergenerational altruism in an OLG framework à la Barro exploiting the quasi-experimental variation generated by reforms of bequest taxation (estate or inheritance tax, in the U.S.) and taxes on inter vivos real estate donations (gift tax, in the U.S.) that were enacted in Italy between 2000 and 2001. Employing a unique data set containing information on the housing stock and house prices in 13 large Italian cities between 1993 and 2004, we identify the structural parameter of interest via the effect of changes in the tax rate on house prices. We find that the intergenerational altruism parameter is about 20%. Given the possible anticipation of the reform this estimate should be interpreted as a lower bound.
