The Path to Gun Control in America Goes through Political Philosophy

This essay argues that gun control in America is a philosophical as well as a policy debate. This explains the depth of acrimony it causes. It also explains why the technocratic public health argument favored by the gun control movement has been so unsuccessful in persuading opponents and motivating supporters. My analysis also yields some positive advice for advocates of gun control: take the political philosophy of the gun rights movement seriously and take up the challenge of showing that a society without guns is a better society, not merely a safer one

Exile the Rich!

The rich have two defining capabilities: independence from and command over others. These make being wealthy very pleasant indeed, but they are also toxic to democracy. First, I analyse the mechanisms by which the presence of very wealthy individuals undermines the two pillars of liberal democracy, equality of citizenship and legitimate social choice. Second, I make a radical proposal. If we value the preservation of democracy we must limit the amount of wealth any individual can have and still be a citizen of our polity

Adam Smith’s Bourgeois Virtues in Competition

Whether or not capitalism is compatible with ethics is a long standing dispute. We take up an approach to virtue ethics inspired by Adam Smith and consider how market competition influences the virtues most associated with modern commercial society. Up to a point, competition nurtures and supports such virtues as prudence, temperance, civility, industriousness and honesty. But there are also various mechanisms by which competition can have deleterious effects on the institutions and incentives necessary for sustaining even these most commercially friendly of virtues. It is often supposed that if competitive markets are good, more competition must always be better. However, in the long run competition enhancing policies that neglect the nurturing and support of the bourgeois virtues may undermine the continued flourishing of modern commercial society

Identity Problems (An Interview with John B. Davis)

In this interview, Professor Davis discusses the evolution of his career and research interests as a philosopher-economist and gives his perspective on a number of important issues in the field. He argues that historians and methodologists of economics should be engaged in the practice of economics, and that historians should be more open to philosophical analysis of the content of economic ideas. He suggests that the history of recent economics is a particularly fruitful and important area for research exactly because it is an open-ended story that is very relevant to understanding the underlying concerns and concepts of contemporary economics. He discusses his engagement with heterodox economics schools, and their engagement with a rapidly changing mainstream economics. He argues that the theory of the individual is “the central philosophical issue in economics” and discusses his extensive contributions to the issue

Electroweak precision measurements and collider probes of the Standard Model with large extra dimensions

The elementary particles of the Standard Model may live in more than 3+1 dimensions. We study the consequences of large compactified dimensions on scattering and decay observables at high-energy colliders. Our analysis includes global fits to electroweak precision data, indirect tests at high-energy electron-positron colliders (LEP2 and NLC), and direct probes of the Kaluza-Klein resonances at hadron colliders (Tevatron and LHC). The present limits depend sensitively on the Higgs sector, both the mass of the Higgs boson and how many dimensions it feels. If the Higgs boson is trapped on a 3+1 dimensional wall with the fermions, large Higgs masses (up to 500 GeV) and relatively light Kaluza-Klein mass scales (less than 4 TeV) can provide a good fit to precision data. That is, a light Higgs boson is not necessary to fit the electroweak precision data, as it is in the Standard Model. If the Higgs boson propagates in higher dimensions, precision data prefer a light Higgs boson (less than 260 GeV), and a higher compactification scale (greater than 3.8 TeV). Future colliders can probe much larger scales. For example, a 1.5 TeV electron-positron linear collider can indirectly discover Kaluza-Klein excitations up to 31 TeV if 500 fb^-1 integrated luminosity is obtained.Comment: 29 pages, LaTe

Transformation without Paternalism

Human development is meant to be transformational in that it aims to improve people's lives by enhancing their capabilities. But who does it target: people as they are or the people they will become? This paper argues that the human development approach relies on an understanding of personal identity as dynamic rather than as static collections of preferences, and that this distinguishes human development from conventional approaches to development. Nevertheless, this dynamic understanding of personal identity is presently poorly conceptualized and this has implications for development practice. We identify a danger of paternalism and propose institutionalizing two procedural principles as side constraints on development policies and projects: the principle of free prior informed consent and the principle of democratic development

Esterification and polyesterification in ionic liquids: towards the synthesis of highly functional polyesters from renewable resources

This thesis concerns the exploration of esterification and transesterification in ionic liquids (ILs) and the use of the knowledge produced by that exploration to inform the efficient synthesis of highly functional polyesters from renewable resources. The first part, Chapter 6, concerns the effect of solvents on acid catalysed esterification. It describes how solvents, including ILs, affect the rate of such reactions and rationalises this influence using Kamlet Taft solvent polarity descriptors. This chapter also touches on more fundamental questions about acidity in ILs and covers Brønsted and Lewis acids. The second part, Chapter 7, explores transesterification in a similar fashion. In this instance, acid, organic base and lipase enzyme are all explored as potential catalysts in ionic and molecular solvents. Again, Kamlet Taft solvent polarity descriptors are used to help rationalise solvent effects. Finally, Chapter 8, describes the use of ILs as solvents for polyesterification and polytransesterification. The relative solubilities of some renewable monomers are determined in a range of ILs and a number of different polycondensations are studied in ILs and molecular solvents considered most appropriate in each case. This Chapter seeks to reach a conclusion about the appropriateness of ILs as solvents for the synthesis of functional polyesters, and the reasons behind that conclusion

Reading About Writing: My Journey Through Authors and Novels in Order to Become a Better Writer

My thesis explores what makes a good novel, and how an author goes about writing a good novel. I begin with my story of trying to write my own novel from the beginning of Freshmen year and continue into my current passion for writing. I start by trying to answer the question “What is a novel?” and go on to look at authors individuals styles which includes how and why they write. Finally I end with a look at how well-written characters make a novel great. Overall, writing a novel comes down to having something important to say or providing your readers with an entertaining story. The importance of novels lies in how well readers can relate to the characters, and if the readers learn something new along with the characters

Model-Independent Description and Large Hadron Collider Implications of Suppressed Two-Photon Decay of a Light Higgs Boson

For a Standard Model Higgs boson with mass between 115 GeV and 150 GeV, the two-photon decay mode is important for discovery at the Large Hadron Collider (LHC). We describe the interactions of a light Higgs boson in a more model-independent fashion, and consider the parameter space where there is no two-photon decay mode. We argue from generalities that analysis of the $t\bar t h$ discovery mode outside its normally thought of range of applicability is especially needed under these circumstances. We demonstrate the general conclusion with a specific example of parameters of a type I two-Higgs doublet theory, motivated by ideas in strongly coupled model building. We then specify a complete set of branching fractions and discuss the implications for the LHC.Comment: 4 pages, 4 figure
