Signing and Signifyin\u27: Negotiating Deaf and African American Identities

For individuals who are both African American and Deaf finding a place to belong is a process of navigating their many cultural identities. In this paper I explore the following questions: where do individuals who are African American and Deaf find and make community? To which communities do they perceive they belong? Is their primary identity African American, Deaf or something else? Does belonging to one community negate membership in another? Does the presence of African American Deaf individuals have an impact on either community or are they forced to create an entirely new one for themselves

Raising the visibility of protected data: A pilot data catalog project

Sharing research data that is protected for legal, regulatory, or contractual reasons can be challenging and current mechanisms for doing so may act as barriers to researchers and discourage data sharing. Additionally, the infrastructure commonly used for open data repositories does not easily support responsible sharing of protected data. This chapter presents a case study of an academic university library’s work to configure the existing institutional data repository to function as a data catalog. By engaging in this project, university librarians strive to enhance visibility and access to protected datasets produced at the institution and cultivate a data sharing culture

The Balance Sheet Channel of Monetary Policy Transmission: Evidence from the UK

This paper examines the sensitivity of investment to cash flow using a panel of UK firms in manufacturing with a view to shedding some light on the existence of a balance sheet channel or financial accelerator. In addition to examining the impact of cash flow in different subsamples based on company size or financial policy (dividend payouts, share issues and debt accumulation), we also investigate the extent to which investment becomes more sensitive to cash flow in periods of monetary tightness. To this end, we employ a monetary tightness indicator constructed for the UK using the narrative approach pioneered by Romer and Romer. The results provide some support for the view that UK firms show greater investment sensitivity to cash flow during periods of tight monetary policy.Financial Constraints; Balance Sheet Channel, Investment.

The Contribution of Sectoral Productivity Differentials to Inflation in Greee

This paper estimates the magnitude of the Balassa-Samuelson effect for Greece. We calculate the effect directly, using sectoral national accounts data, which permits estimation of total factor productivity (TFP) growth in the tradeables and nontradeables sectors. Our results suggest that it is difficult to produce one estimate of the BS effect. Any particular estimate is contingent on the definition of the tradeables sector and the assumptions made about labour shares. Moreover, there is also evidence that the effect has been declining through time as Greek standards of living have caught up on those in the rest of the world and as the non-tradeables sector within Greece catches up with the tradeables.Balassa-Samuelson effect, inflation, productivity

Capital Flows and Speculative Attacks in Prospective EU Member States

This paper examines the capital flow experience of transition economies who are also prospective EU members with a view to shedding light on the likely problems they might encounter with exchange rate policy in the run up to euro area membership. We show that they have been experiencing fairly sizeable capital flows since the early 1990s. We explain these flows using two separate models. The first explains the level of capital flows using panel data from the prospective EU members. The second concentrates specifically on estimating the probability of a country experiencing downward speculative pressure. In both cases, the contribution of domestic factors and contagion is explored. The results suggest that while domestic factors have some role to play, it is rather limited. Moreover there is clear evidence of contagion effects, suggesting that macroeconomic policy in the prospective EU members will be complicated by capital flows in the run up to euro area membership.capital flows, transition economies, accession countries and EU membership

Large-scale atomistic density functional theory calculations of phosphorus-doped silicon quantum bits

We present density functional theory calculations of phosphorus dopants in bulk silicon and of several properties relating to their use as spin qubits for quantum computation. Rather than a mixed pseudopotential or a Heitler-London approach, we have used an explicit treatment for the phosphorus donor and examined the detailed electronic structure of the system as a function of the isotropic doping fraction, including lattice relaxation due to the presence of the impurity. Doping electron densities and spin densities are examined in order to study the properties of the dopant electron as a function of the isotropic doping fraction. Doping potentials are also calculated for use in calculations of the scattering cross-sections of the phosphorus dopants, which are important in the understanding of electrically detected magnetic resonance experiments. We find that the electron density around the dopant leads to non-spherical features in the doping potentials, such as trigonal lobes in the (001) plane at energy scales of +12 eV near the nucleus and of -700 meV extending away from the dopants. These features are generally neglected in effective mass theory and will affect the coupling between the donor electron and the phosphorus nucleus. Our density functional calculations reveal detail in the densities and potentials of the dopants which are not evident in calculations that do not include explicit treatment of the phosphorus donor atom and relaxation of the crystal lattice. These details can also be used to parameterize tight-binding models for simulation of large-scale devices.Comment: 22 pages, 8 figure

Oculomotor examination of the weapon focus effect: does a gun automatically engage visual attention?

A person is less likely to be accurately remembered if they appear in a visual scene with a gun, a result that has been termed the weapon focus effect (WFE). Explanations of the WFE argue that weapons engage attention because they are unusual and/or threatening, which causes encoding deficits for the other items in the visual scene. Previous WFE research has always embedded the weapon and nonweapon objects within a larger context that provides information about an actor's intention to use the object. As such, it is currently unknown whether a gun automatically engages attention to a greater extent than other objects independent of the context in which it is presente
