Talk Title: Growth, Electrical and Magnetic Characterization of Nitride Dilute Magnetic Semiconductors

Date: Monday, October 5th
Time: 4:00 to 5:00 PM
Refreshments: 3:30 to 4:00
Room: Wilsdorf 101

Abstract:

Spintronics is an emerging technology which exploits for the first time the electrons' spin while making use of their charge. While traditional electronics are based on charge carrier control (e.g., n- or p-type), functional magnetic semiconductors called dilute magnetic semiconductors (DMS) would also allow control of the quantum spin (e.g., up or down). Future spintronic devices can take advantage of the
new type of electronic conduction control and can be quite faster and more efficient as compared to the traditional counterparts. However, one of the greatest challenges in making DMS useful is obtaining reliable Curie (i.e., ferromagnetic) transition temperature above 300K. In this
presentation, I will present the current efforts in obtaining reliable (e.g., above 300K) Curie temperature for manganese doped gallium arsenite (MnGaAs) and manganese doped gallium nitride (MnGaN) DMS materials. I will describe the
growth, electrical and magnetic characterization of manganese doped scandium nitride (MnScN) and iron doped scandium nitride (FeScN) grow on scandium nitride/magnesium oxide [ScN/MgO(001)] by molecular beam epitaxy as possible nitride
DMS materials.

STS Colloquium, Thursday, October 8th - The Regulatory Governance of Nicotine in the UK

Department of Science, Technology and Society
Fall 2009 Colloquium Series

Speaker: Catriona Rooke, Science and Society, University of Nottingham
Title: The Regulatory Governance of Nicotine in the UK
Date: Thursday, October 8th, 2009
Time: 3:30 - 5:00 p.m.
Location: Rodman Room (A207), Thornton Hall

Abstract:
Recently, within the tobacco control community, there has been growing concern that the division of regulatory responsibility for conventional tobacco products (i.e. cigarettes, cigars, pipe tobacco) and alternative modes of nicotine delivery (or ?Nicotine Replacement Therapies’ (NRTs) such as gums, patches and inhalers) is having a negative effect on the reduction of smoking rates in industrialized countries (MHRA 2006). The ?alternatives’ are mainly regulated as pharmaceuticals; therefore, must reach safety standards comparable with those required for medications rather than being compared with the known harm caused by tobacco smoking. This paper will draw on Actor-Network Theory (ANT) ideas (particularly Latour, 1988; Law, 1987) to study the evolution of this divided responsibility in the United Kingdom, particularly how NRTs came to be regulated as pharmaceuticals.

I draw on scientific, policy and legal documents, together with oral history interviews, to explore the regulatory decisions taken in the UK in respect of the first NRT: a nicotine-containing gum developed in Sweden. This gum, as /Nicorette/, became available in the UK in 1980 as a prescription only medicine under the 1968 Medicines Act. It is proposed that utilizing ANT to explore the development of nicotine gum and the regulatory decisions taken about it in the UK, places these decisions into the wider context of ideas about tobacco control and addiction, and helps to better understand how different substances such as tobacco, nicotine and nicotine gum acted in different networks, leading to very different systems of regulation. More broadly, this paper explores the possibilities that ANT provides for shedding light on a historical case study, as well as whether ANT has the potential to be a useful tool for studying regulatory governance.

Brief Bio:
Catriona is a graduate student at the Institute for Science and Society at the University of Nottingham (UK). She has an undergraduate degree in Sociology from the University of Newcastle and a masters degree in Social Research from the University of Aberdeen. Catriona will be visiting through a U21 travel scholarship [Universitas 21, an international network of 21 leading research-intensive universities in 13 countries - UVa is the only American University]. Catriona is
working on a project that explores the evolution of regulatory strategies in relation to Nicotine Replacement Therapies and their implications for product innovation and harm reduction. She is currently investigating the utility of Actor-Network Theory for exploring these issues.

Portfolio Choice with Capital Gain Taxation and the Limited Use of Losses

We study an investor's consumption-savings problem with realized capital gain taxation. The distinguishing feature of our analysis is that we impose an important element of the tax code that has received little attention in the academic literature: the limited use of capital losses. Existing capital gain tax portfolio choice work assumes the full use of capital losses (FUL) implying unused capital losses generate tax rebates. We show that this common assumption leads to counterfactual welfare results. Due to tax rebates generated from tax loss selling, an untaxed investor would actually prefer to pay a capital gain tax. Instead, when only the limited use of capital losses (LUL) is allowed for, which is consistent with the U.S. tax code, an investor's optimal equity-to-wealth ratio is shown to be strongly non-monotonic in the portfolio's tax basis. For a tax basis significantly below the current stock price, LUL investors with no unrealized capital losses trade equity similar to FUL investors as the probability of tax loss selling in the future is small. For a tax basis close to the current stock price, LUL investors hold significantly less equity relative to FUL investors and untaxed investors. When LUL investors have large unused capital losses or a tax basis significantly above the current stock price, they trade as if they are not taxed on capital gains because they can use accumulated capital losses to offset any future taxes. This difference in trading strategies and the usage of capital losses leads to lower lifetime wealth and equity holdings for LUL investors relative to FUL investors and untaxed investors.

Clement Chen - A Strategic Perspective on the "Biology" of Smart Grid
Time: 3-6PM
Location: MEC 205

Smart grid is commonly viewed as the "internetization" of the electric power system that promises to help enable a sustainable
energy future. The question that is not often asked is what happens when millions of new entities join the grid as "micro" utilities
and start interacting with an infrastructure that is becoming highly networked with ever-increasing automation. This trend
points to an environment that may become increasingly "biological" and lend itself to unintended consequences.
