Effective non-vanishing for Fano weighted complete intersections

We show that Ambro-Kawamata's non-vanishing conjecture holds true for a quasi-smooth WCI X which is Fano or Calabi-Yau, i.e. we prove that, if H is an ample Cartier divisor on X, then |H| is not empty. If X is smooth, we further show that the general element of |H| is smooth. We then verify Ambro-Kawamata's conjecture for any quasi-smooth weighted hypersurface. We also verify Fujita's freeness conjecture for a Gorenstein quasi-smooth weighted hypersurface. For the proofs, we introduce the arithmetic notion of regular pairs and enlighten some interesting connection with the Frobenius coin problem.Comment: 27 pages.

Civil Disobedience and the Duty to Obey the Law: A Critical Assessment of Lefkowitz\u27s View

In this paper I critically assess David Lefkowitz’s view that the right to political participation encompasses a right to suitably constrained civil disobedience. I claim that his argument is not successful because it has an explanatory gap. I then examine two strategies for repairing his argument. The first attempts to show that acts of civil disobedience fulfill the duty to obey the law. The second attempts to establish that the moral value of civil disobedience outweighs the moral value of obeying the law. I argue that both strategies may be successful—to a certain extent—but only the latter can establish a right to civil disobedience

Mapping Global Theatre Histories

Tanks to all at Palgrave Macmillan who encouraged and shaped this project, especially Nicola Cattini, Tomas Rene, Vicky Bates, and the anonymous readers of the proposal. Tanks to the colleagues who gave me insights, including Dean Adams, Allison Amidei, Bruce Auerbach, Hala Baki, Tomas Burch, Carlos Cruz, Kaja Dunn, David Fillmore, Andrew Hartley, Jorge Huerta, Rick Kemp, Chuyun Oh, Kaustavi Sarkar, Dylan Savage, Joanne Tompkins, Robin Witt, Amanda Zhou, and members of the “Pedagogy of Extraordinary Bodies” working group at the American Society for Teatre Research conference in fall 2017. Tanks also to Chuyun Oh and Kaustavi Sarkar for help with illustrations here. And thanks to the authors and editors of Wikipedia, who have made many details of theatre history quickly accessible online, with further references given as well. Tanks to the colleagues who responded to my e-mail query in summer 2017 about a potential theatre history textbook, especially Sarah Bay-Cheng, Cheryl Black, Sara Ellen Brady, David Carlyon, Teresa DurbinAmes, Susan Kattwinkel, Maiya Murphy, John O’Connor, Felicia Ruf, Shannon Blake Skelton, and Nathan Tomas. Tanks to the artists I have met, who gave me insights about their work. Tese included Kazimierz Braun (who directed me in Te Card Index at the University of Notre Dame in 1982, welcomed my visit to his theatre in Poland, and co-wrote a play with me that he staged at Swarthmore College in 1986), Herbert Blau (my dissertation mentor, 1988–1992), Ola Rotimi (who lectured in one of my classes), William Sun (who discussed playwriting with me and introduced me to others), Richard Schechne

How Landscapes Make Science: Italian National Narrative, The Great Mediterranean, and Giuseppe Sergi’s Biological Myth

The perception and representation of landscape are not natural facts but are cultural constructions of human agents. In this chapter, I aim at deconstructing the role of pre-classical archaeology of Eastern Mediterranean in the process of Italian nation building between the nineteenth and the twentieth centuries. In particular, I focus on how a substantial group of Italian intellectuals deployed archeological discoveries to construct the Mediterranean as a representational space, which eventually served as a platform for their nationalistic political discourses. To this end, I discuss the spreading of these new conceptions in the Italian cultural debate at large. A prominent figure in this debate was Giuseppe Sergi. By reconstructing his views on the connections between national identity and biology, I demonstrate the considerable performative effect of the Mediterranean as a symbolic space and source of meaning on Italian culture. Furthermore, I argue that this new role of the Mediterranean resulted from a negotiation between the archaeological discovery of pre-classical past and the political aspirations of those scholars who opposed Italian foreign and interior politics of the period

Cubic rational expressions over a finite field

We classify the cubic rational expressions $g(x)/h(x)$ over a finite field, having at most three ramification points, under an equivalence relation given by pre- and post-composition with independent M\"obius transformations.Comment: 22 pages; minor update involving a choice of some simpler representatives in Theorems 19 and 2

Beyond Personalization: Research Directions in Multistakeholder Recommendation

Recommender systems are personalized information access applications; they are ubiquitous in today's online environment, and effective at finding items that meet user needs and tastes. As the reach of recommender systems has extended, it has become apparent that the single-minded focus on the user common to academic research has obscured other important aspects of recommendation outcomes. Properties such as fairness, balance, profitability, and reciprocity are not captured by typical metrics for recommender system evaluation. The concept of multistakeholder recommendation has emerged as a unifying framework for describing and understanding recommendation settings where the end user is not the sole focus. This article describes the origins of multistakeholder recommendation, and the landscape of system designs. It provides illustrative examples of current research, as well as outlining open questions and research directions for the field.Comment: 64 page

Sliding from margin to the flow: the mobility of canoe in the art of evironmental education

[Resumo] Cultura e ciência pelas mãos da educação ambiental é a proposta do Grupo Pesquisador em Educação Ambiental, Comunicação e Arte por meio de um projeto internacional relacionado com a avaliação ecossistêmica do milênio. Partindo da premissa que nem tudo vira mercado, a pesquisa teve a fenomenologia como metodologia e a meta de interpretar a feitura de uma canoa à luz da cultura local. Para além de um instrumento de mobilidade, a canoa pode ser interpretada como uma escultura de arte da expressão mais da cultura local, que deve ser reconhecida como um saber popular e que confere a identidade de uma região.[Abstract] Culture and science in the hands of environmental education is the proposal of the Research Group on Environmental Education, Communication and the Arts through an international project related to the Millennium Ecosystem Assessment. Assuming that not everything turns market, this research had the phenomenology as a methodology, and aims to interpret the making of a canoe in the light of local culture. Transcendent a simple mobility tool, the canoe can be interpreted as an expression of art sculpture belonging to the local culture, and should be recognized as a popular knowledge, which can shape the identity of a region
