  • Me, Myself & Mine: the Scope of Ownership
    ME, MYSELF & MINE The Scope of Ownership _________________________________ PETER MARTIN JAWORSKI _________________________________ May, 2012 Committee: Fred Miller (Chair) David Shoemaker, Steven Wall, Daniel Jacobson, Neil Englehart ii ABSTRACT This dissertation is an attempt to defend the following thesis: The scope of legitimate ownership claims is much more narrow than what Lockean liberals have traditionally thought. Firstly, it is more narrow with respect to the particular claims that are justified by Locke’s labour- mixing argument. It is more difficult to come to own things in the first place. Secondly, it is more narrow with respect to the kinds of things that are open to the ownership relation. Some things, like persons and, maybe, cultural artifacts, are not open to the ownership relation but are, rather, fit objects for the guardianship, in the case of the former, and stewardship, in the case of the latter, relationship. To own, rather than merely have a property in, some object requires the liberty to smash, sell, or let spoil the object owned. Finally, the scope of ownership claims appear to be restricted over time. We can lose our claims in virtue of a change in us, a change that makes it the case that we are no longer responsible for some past action, like the morally interesting action required for justifying ownership claims. iii ACKNOWLEDGEMENTS: Much of this work has benefited from too many people to list. However, a few warrant special mention. My committee, of course, deserves recognition. I’m grateful to Fred Miller for his many, many hours of pouring over my various manuscripts and rough drafts.

    Political Science 270 Mechanisms of International Relations Hein Goemans Course Information: Harkness 337 Spring 2016 Office Hours: Wed. 2 { 3 PM 16:50{19:30 Wednesday [email protected] Meliora 203 The last fifteen years or so saw a major revolution in the social sciences. Instead of trying to discover and test grand \covering laws" that have universal validity and tremendous scope| think Newton's gravity or Einstein's relativity|the social sciences are in the process of switch- ing to more narrow and middle-range theories and explanations, often referred to as causal mechanisms. Recently, however, a new so-called \behavioral" approach { often but not always complementary { is currently sweeping the field. Since mechanisms remain the core theoretical building blocks in our field, we will continue to focus on them. In the bulk of this course students will be introduced to a range of such causal mechanisms with applications in international relations. Although these causal mechanisms can loosely be described in prose, explicit formalization { e.g., math { allows for a much deeper and richer understanding of the phenomena of study. In other words, formalization enables simplification and thus a better understanding of what is \really" going on. To set us on that path, we begin with some very basic rational choice fundamentals to introduce you to formal models in a rigorous way to show the power and potential of this approach. In other words, there will be some *gasp* Algebra. For much of the very brief but essential introduction to game theory we will use William Spaniel's Channel (http://gametheory101.com/courses/game-theory-101/, also on YouTube), as well as his cheap but very highly rated introductory book Game Theory 101: The Complete Textbook available at Amazon (http://www.amazon.com).

  • Making Sense of State Socialization
    Review of International Studies (2001), 27, 415–433 Copyright © British International Studies Association Making sense of state socialization KAI ALDERSON Abstract. At present, International Relations scholars use the metaphor of ‘state socializ- ation’ in mutually incompatible ways, embarking from very different starting points and arriving at a bewildering variety of destinations. There is no consensus on what state socializ- ation is, who it affects, or how it operates. This article seeks to chart this relatively unmapped concept by defining state socialization, differentiating it from similar concepts, and exploring what the study of state socialization can contribute to important and longstanding theoretical debates in the field of international relations. Introduction Norms are gaining ground in the study of International Relations.1 Not only are they the focus of extensive conceptual and theoretical work, but international norms are increasingly seen as weight-bearing elements of explanatory theories in issue- areas ranging from national security to the study of international organization.2 Regime theory continues to generate an extraordinarily fecund research pro- gramme,3 and its central insight—that relations among competitive sovereign states are shot through with norms of cooperation—links contemporary scholarship to long-standing reflections on the nature of the international.4 Constructivist scholars, for their part, argue that social norms offer a radical alternative to interest- and power-based accounts of international politics.5 1 As readily attested by the contributions to the recent fiftieth anniversary edition of International Organization, 52: 4 (1998).

  • Successful Masculinity in Search of the Alpha Within
    UNIVERSITY OF TAMPERE School of Communication, Media and Theatre Successful Masculinity In Search of the Alpha Within Dermot Lyons Pro Gradu – Master’s Thesis June 2015 UNIVERSITY OF TAMPERE School of Communication, Media and Theatre LYONS, DERMOT: Successful Masculinity: In Search of the Alpha Within Pro Gradu – Master’s Thesis, 133 pages. Journalism and Communication / Media Culture June 2015 Abstract Pickup artists and the seduction community have gone from being an underground network of workshop and internet based teachers and students, to, following the publication of Neil Strauss’ book ‘The Game: Penetrating the Secret Society of Pickup Artists’, a movement entering the wider public consciousness, a subculture of (primarily) men who wish to get better at meeting, sleeping with, and dating women. They try to make the transformation from men who are not successful socially or with women, termed ‘AFC’s or ‘Average Frustrated Chumps’ in the seduction community, to PUAs, or PickUp Artists. There are now seduction companies, TV shows, radio shows, podcasts, blogs, books, forums, websites, chat rooms, and community groups for major cities all across the world. This material is not always practiced or preached in a mainstream-safe way, but rather is done by breaking through groupthink, going against perceived norms, not being politically correct, and using the findings of evolutionary psychology and life coaching. The thinking behind this is: Everything can be taught, so why not how to get girls? Game is (supposed to be) a fun, pleasurable way to improve your overall self: diet, exercise, hygiene, education, career, living circumstance, behavior, sociability – all are looked at towards bettering an overall enhanced version of yourself, almost quantifiable, to be the most optimal self you can be, where you are having a good life, and women are a part of that life, who may join you on your own individual journey as a man.

  • Adam Przeworski: Capitalism, Democracy and Science
    ADAM PRZEWORSKI: CAPITALISM, DEMOCRACY AND SCIENCE Interview with Adam Przeworski conducted and edited by Gerardo L. Munck February 24, 2003, New York, New York Prepared for inclusion in Gerardo L. Munck and Richard Snyder, Passion, Craft, and Method in Comparative Politics. Training and Intellectual Formation: From Poland to the United States Q: How did you first get interested in studying politics? What impact did growing up in Poland have on your view of politics? A: Given that I was born in May of 1940, nine months after the Germans had invaded and occupied Poland, any political event, even a minor one, was immediately interpreted in terms of its consequences for one’s private life. All the news was about the war. I remember my family listening to clandestine radio broadcasts from the BBC when I was three or four years old. After the war, there was a period of uncertainty, and then the Soviet Union basically took over. Again, any rumbling in the Soviet Union, any conflict between the Soviet Union and the United States, was immediately seen in terms of its consequences for our life. It was like this for me until I first left for the US in 1961, right after the Berlin Wall went up. One’s everyday life was permeated with international, macro-political events. Everything was political. But I never thought of studying politics. For one thing, in Europe at that time there really was no political science. What we had was a German and Central European tradition that was called, translating from German, “theory of the state and law.” This included Carl Schmitt and Hans Kelsen, the kind of stuff that was taught normally at law schools.

  • The Economics of Privacy †
    Journal of Economic Literature 2016, 54(2), 442–492 http://dx.doi.org/10.1257/jel.54.2.442 The Economics of Privacy † Alessandro Acquisti, Curtis Taylor, and Liad Wagman* This article summarizes and draws connections among diverse streams of theoretical and empirical research on the economics of privacy. We focus on the economic value and consequences of protecting and disclosing personal information, and on consumers’ understanding and decisions regarding the trade-offs associated with the privacy and the sharing of personal data. We highlight how the economic analysis of privacy evolved over time, as advancements in information technology raised increasingly nuanced and complex issues. We find and highlight three themes that connect diverse insights from the literature. First, characterizing a single unifying economic theory of privacy is hard, because privacy issues of economic relevance arise in widely diverse contexts. Second, there are theoretical and empirical situations where the protection of privacy can both enhance and detract from individual and societal welfare. Third, in digital economies, consumers’ ability to make informed decisions about their privacy is severely hindered because consumers are often in a position of imperfect or asymmetric information regarding when their data is collected, for what purposes, and with what consequences. We conclude the article by highlighting some of the ongoing issues in the privacy debate of interest to economists. ( JEL D82, D83, G20, I10, L13, M31, M37) 1.
