Characterizing core stability with fuzzy games
No full textShellshear E. Characterizing core stability with fuzzy games. Working Papers. Institute of Mathematical Economics. Vol 410. Bielefeld: Universität Bielefeld; 2009.This paper investigates core stability of cooperative, TU games via a fuzzy extension of the totally balanced cover of a TU game. The stability of the core of the fuzzy extension of a game, the concave extension, is shown to reflect the core stability of the original game and vice versa. Stability of the core is then shown to be equivalent to the existence of an equilibrium of a certain correspondence
A note on apportionment methods
No full textShellshear E. A note on apportionment methods. Working Papers. Institute of Mathematical Economics. Vol 391. Bielefeld: Universität Bielefeld; 2007.This paper investigates the suitability of apportionment methods based on the idea of preserving the coalition function of the simple game represented by the populations of the states. The results show that an apportionment method which satisfies desirable properties such as population monotonicity, house monotonicity, etc., does not exist. A classification of simple voting games via winning coalitions is also given
On core stability and extendability
No full textShellshear E. On core stability and extendability. Working Papers. Institute of Mathematical Economics. Vol 387. Bielefeld: Universität Bielefeld; 2007.This paper investigates conditions under which the core of a TU cooperative game is stable. In particular the author extends the idea of extendability to find new conditions under which the core is stable. It is also shown that these new conditions are not necessary for core stability

Über Corestabilität und Zuteilungsverfahren
No full textShellshear E. On core stability and apportionment methods. Bielefeld (Germany): Bielefeld University; 2008.In the thesis two distinct topics in cooperative game theory are investigated. The first problem analyzed is one of the oldest unsolved problems in cooperative game theory. The question asks, under what conditions does an n-person, cooperative, TU game have a stable core? This problem is fundamental for n-person, cooperative, TU game theory as the solution of this problem would provide vital insights into certain properties of the core as well as revealing certain aspects of von Neumann-Morgernstern stable sets. In the thesis new sufficient conditions for core stability are found that turn out to also be necessary for certain classes of games.
In the second chapter of the dissertation the question of core stability is analyzed from a different perspective using the concept of a fuzzy game. This style of game is used to provide new necessary and sufficient conditions for core stability in terms of properties of two correspondences.
The second topic examined in this PhD, in the third chapter, concerns what is known as the apportionment problem. The problem in question is how one can apportion seats, power, etc., in a parliament, committee, etc., corresponding to the size, power, etc., of certain states or parties within a country, company, etc. One is confronted with this problem as soon as one wishes to represent the interests of certain groups in some sort of committee. Hence, this problem is age old but has only recently received a proper mathematical treatment in the twentieth century. In this thesis, a new apportionment method based on game theoretical concepts is investigated for its suitability as an apportionment method to be applied in reality. It is shown that the new apportionment does not fulfill certain desirable criteria. In addition, variations of the new apportionment methods are considered
Ep. #154 - Evan Berry
No full textThis recording and transcript form part of a collection of podcasts conducted by the Cultures of Energy at Rice University. Cultures of Energy brings writers, artists and scholars together to talk, think and feel their way into the Anthropocene. We cover serious issues like climate change, species extinction and energy transition. But we also try to confront seemingly huge and insurmountable problems with insight, creativity and laughter.Cymene and Dominic rediscover the Violent Femmes on this week's podcast and that prompts a discussion of the best albums of all time. We then (18:54) welcome American U’s Evan Berry to the podcast, author of Devoted to Nature: The Religious Roots of American Environmentalism (U California Press, 2015) and the PI of a Luce Foundation funded project on “Religion and Climate Change in Cross-Regional Comparison.” We start with the Pope and his views on climate change and then quickly move on to Evan’s argument that much apparently secular environmentalist thinking has deep affinities with Christian theology. We revisit Lynn White’s famous argument that Christianity devalues nature, discuss the need to move past “great man” narratives of the evolution of environmentalism, and ruminate on what 19th century Christian environmentalists considered to be the “moral salubriousness of nature.” Evan shares his thoughts on how Protestant nominalism may have informed American climate denialism over time and also about how walking as a form of “recreational salvation” became linked to the valorization of wilderness. We discuss whether American Christianity is exceptional in terms of climate morality and why American political culture has become an incubator for religious radicalism. We then turn to how climate change is now impacting religious systems across the world and how better intergenerational ethics might teach us to think collectively rather than individually. Finally, we discuss another recent book project Evan has undertaken with Rob Albro, Church, Cosmovision, and the Environment: Religion and Social Conflict in Contemporary Latin America (Routledge 2018)

Poser
No full textPoser is a book of poems consisting of seven sections. The poems inside the book deal with a range of topics, but focus centrally around the development of identity in contemporary society. The work calls to question the paths human beings seek in order to affirm selfhood, and deals heavily with the psychological problem known as "Imposter Syndrome." The sections address distinct periods of development and their corresponding spiritual, social, and human inquiries, which end up defining the shapes of our lives.M.F.A.Includes bibliographical referencesby Evan Gill Smit
