Geometric Invariant Theory for Polarized Curves

By: Gilberto Bini,Fabio Felici,Margarida Melo,Filippo Viviani

We investigate GIT quotients of polarized curves. More specifically, we study the GIT problem for the Hilbert and Chow schemes of curves of degree d and genus g in a projective space of dimension d-g, as d decreases with respect to g. We prove that the first three values of d at which the GIT quotients change are given by d=a(2g-2) where a=2, 3.5, 4. We show that, for a>4, L. Caporaso's results hold true for both Hilbert and Chow semistability. If 3.5a

Combinatorial Algebraic Geometry

Levico Terme, Italy 2013, Editors: Sandra Di Rocco, Bernd Sturmfels

By: Aldo Conca,Sandra Di Rocco,Jan Draisma,June Huh,Bernd Sturmfels,Filippo Viviani

Combinatorics and Algebraic Geometry have enjoyed a fruitful interplay since the nineteenth century. Classical interactions include invariant theory, theta functions and enumerative geometry. The aim of this volume is to introduce recent developments in combinatorial algebraic geometry and to approach algebraic geometry with a view towards applications, such as tensor calculus and algebraic statistics. A common theme is the study of algebraic varieties endowed with a rich combinatorial structure. Relevant techniques include polyhedral geometry, free resolutions, multilinear algebra, projective duality and compactifications.

Security and Trust in Online Social Networks

By: Barbara Carminati,Elena Ferrari,Marco Viviani

The enormous success and diffusion that online social networks (OSNs) are encountering nowadays is vastly apparent. Users' social interactions now occur using online social media as communication channels; personal information and activities are easily exchanged both for recreational and business purposes in order to obtain social or economic advantages. In this scenario, OSNs are considered critical applications with respect to the security of users and their resources, for their characteristics alone: the large amount of personal information they manage, big economic upturn connected to their commercial use, strict interconnection among users and resources characterizing them, as well as user attitude to easily share private data and activities with strangers. In this book, we discuss three main research topics connected to security in online social networks: (i) trust management, because trust can be intended as a measure of the perception of security (in terms of risks/benefits) that users in an OSN have with respect to other (unknown/little-known) parties; (ii) controlled information sharing, because in OSNs, where personal information is not only connected to user profiles, but spans across users' social activities and interactions, users must be provided with the possibility to directly control information flows; and (iii) identity management, because OSNs are subjected more and more to malicious attacks that, with respect to traditional ones, have the advantage of being more effective by leveraging the social network as a new medium for reaching victims. For each of these research topics, in this book we provide both theoretical concepts as well as an overview of the main solutions that commercial/non-commercial actors have proposed over the years. We also discuss some of the most promising research directions in these fields.

Tao Te Ching

Yielding with Integrity Lao Tzu

By: Cristina I. Viviani

A joy to read this gem-like treasure of the Tao Te Ching is accessible, inclusive, poetic, and insightful. The Tao is an invitation to be in the flow of life in harmony with all beings and all things. This new version encourages us to begin from stillness and simply respond from an inner calm, quiet, and intuitive listening. Our innate sense of knowing through not-knowing is much needed in today’s world. Discover how grace and ease most often appear by yielding to Lao Tzu’s much cherished wisdom. “Cristina Viviani’s inviting new translation of the Tao Te Ching captures both the simplicity and the complexity of these ancient teachings. In language that is clear, accessible, and possessed of a warmth sometimes lacking in other translations, Viviani’s Tao Te Ching honors both the poetry and the philosophy of Taoism’s central text.” —John Brehm, author of The Dharma of Poetry “Beautiful and wise.” —Dr. Alberto Pérez-Gómez, Emeritus Professor, Profesor Honoris Causa “I’m completely smitten! Loving this translation (even though Stephen Mitchell’s has been my long-time favorite). I’m delighted to read and be immersed in this profoundly beautiful creation and integrate the wisdom and beauty the Tao brings. Now, I’m looking forward to holding this book in my hands and keeping it close by.” —Moni Vangolen, Stillness Facilitator

Over 100 Fabulous, Quick, and Easy Recipes

By: Fabio Viviani

“In this amazing book, Fabio shows you how to make delicious Italian dishes easily and quickly! It’s the next best thing to having him in your kitchen.” —Antonia Lofaso, Chef and Restaurateur of Scopa Italian Roots, The Local Peasant, Sycamore Tavern and Black Market Liquor Bar Dinner doesn’t have to be daunting. In half an hour or less you can cook up an Italian meal at home like a professional chef. In this case, just like Top Chef star Fabio Viviani. Infused with his warmth and humor, this book brings Fabio into your kitchen. If Fresh Fettuccini with Manila Clams and Spicy Sausages and Chicken Pizzaiola with Mozzarella and Pepperoni seem like recipes that are out of reach, think again. Fabio shows home chefs how to cook “Grandma Style” (that is, like an intuitive Italian), and even those on a tight schedule will soon be whipping up great dinners. The over 100 no-fail recipes include Mascarpone and Ricotta-Stuffed Peaches, 15-Minute Seafood Cioppino, and Salted Caramel Chocolate Cake. Fabio’s 30 Minute Italian provides lots of time saving tips, from freezing batches of herbs and dressing to making your own pasta dough in three minutes tops. Along the way, Fabio shares stories from his early life in Florence where he apprenticed at age five to his wheel-chair-bound and wooden-spoon-wielding great-grandmother to his American life cooking dinner for his wife and infant son in Chicago. Gorgeously illustrated throughout, and filled with his through-the-roof energy and charisma, Fabio’s 30 Minute Italian is guaranteed to make you enjoy your time in the kitchen—and the results!

Why are women more food insecure than men? Exploring socioeconomic drivers and the role of COVID-19 in widening the global gender gap

Background paper for The status of women in agrifood systems

By: Mane, E.,Giaquinto, A.M.,Cafiero, C.,Viviani, S.,Anríquez, G.

Women face a higher prevalence of food insecurity than do men, both on a global scale and across all regions. This paper delves into the global determinants contributing to the gender gap in food insecurity and explores how the COVID-19 pandemic influenced its trajectory. Additionally, it estimates the impact of improvements in food security and incomes possible if gender gaps on farm productivity and wages were closed. Utilizing data from the Food Insecurity Experience Scale gathered from over 700 000 individuals across 121 countries, this study reveals that individuals aged 25–34 years, irrespective of their gender, and women residing in rural areas have been disproportionately affected by the pandemic. The econometric model allows the authors to estimate the elasticities of food security to income, which they then use to simulate the potential macrolevel benefits for the economy and food security if we were to eliminate the gender gaps in farm productivity and wages within agrifood systems. The findings suggest that addressing these disparities could result in an approximate USD 1 trillion increase in global gross domestic product and lift approximately 45 million people out of food insecurity. Additionally, the authors estimate that eliminating these gender disparities could reduce the current gap in food insecurity between women and men by at least 57 percent. This background paper was prepared to inform Chapters 1 and 6 of FAO’s report on The status of women in agrifood systems.

Access to food in 2021: filling data gaps

Results of twenty national surveys using the Food Insecurity Experience Scale (FIES)

By: Cafiero, C., Gheri, F., Kepple, A.W., Rosero Moncayo, J., Viviani, S.

This report presents the results of assessments based on the food insecurity experience scale (FIES), data collected by FAO in twenty least developed countries (LDCs), landlocked developing countries (LLDCs) and Small Island Developing States (SIDS) between November 2021 and February 2022. For nine of the countries (including eight SIDS), it was the first time FIES data had been collected. The surveys described in the report were conducted to provide accurate and timely food insecurity assessments of the 20 countries for which food security data are scarce. The detailed results, presented at the subnational level, can support country-level decision-making and will also inform the monitoring of the Sustainable Development Goals (SDGs) and targets, specifically SDG Target 2.1.

Moduli of K-stable Varieties

By: Giulio Codogni,Ruadhaâi Dervan,Filippo Viviani

This volume is an outcome of the workshop "Moduli of K-stable Varieties", which was held in Rome, Italy in 2017. The content focuses on the existence problem for canonical Kèahler metrics and links to the algebro-geometric notion of K-stability. The book includes both surveys on this problem, notably in the case of Fano varieties, and original contributions addressing this and related problems. The papers in the latter group develop the theory of K-stability; explore canonical metrics in the Kèahler and almost-Kèahler settings; offer new insights into the geometric significance of K-stability; and develop tropical aspects of the moduli space of curves, the singularity theory necessary for higher dimensional moduli theory, and the existence of minimal models. Reflecting the advances made in the area in recent years, the survey articles provide an essential overview of many of the most important findings. The book is intended for all advanced graduate students and researchers who want to learn about recent developments in the theory of moduli space, K-stability and Kèahler-Einstein metrics.
