Working Memory In Simultaneous Interpreters: Effects Of Task And Age, Teresa Signorelli, Henk Haarmann, Loraine Obler

Publications and Research

This study examines whether interpreters have better working memory (WM) than noninterpreters, taking into account different WM components and the potential modulatory influence of age. Younger and older interpreters and non-interpreters were tested on reading span, nonword repetition, and order- and category-cued recall, using English, second-language materials. Articulation rate was also assessed. Interpreters outperformed non-interpreters in reading span and nonword repetition, but not cued recall and articulation rate. These results suggest that interpreters have better ability to manipulate information in working memory and process or store sub-lexical phonological representations, but have no advantage in short-term retention of words and their …

Italian Militants And Migrants And The Language Of Solidarity In The Early- Twentieth-Century Western Coalfields, Stephen Brier, Ferdinando Fasce

Publications and Research

This article uses the life and experiences of an Italian immigrant and labor militant, Carlo Demolli, to examine a range of issues, including: the intersection of ethnic and national identity and labor militancy and solidarity in the organizing efforts of the United Mine Workers of America (UMWA) among the ethnically diverse workforce of coal miners in the American West at the turn of the 20th century; the role of a "language of solidarity" as expressed in an Italian language version of the UMW Journal, Il Lavoratore Italiano, in sustaining a militant Italian immigrant workforce in the coal mines; and the …

Quantifying Uncertainty In Urban Flooding Analysis Considering Hydro-Climatic Projection And Urban Development Effects, Il-Won Jung, Heejun Chang, Hamid Moradkhani

Geography Faculty Publications and Presentations

How will the combined impacts of land use change, climate change, and hydrologic modeling influence changes in urban flood frequency and what is the main uncertainty source of the results? Will such changes differ by catchment with different degrees of current and future urban development? We attempt to answer these questions in two catchments with different degrees of urbanization, the Fanno catchment with 84% urban land use and the Johnson catchment with 36% urban land use, both located in the Pacific Northwest of the US. Five uncertainty sources – general circulation model (GCM) structures, future greenhouse gas (GHG) emission scenarios, …

Contribution Of Public Investments And Innovations To Total Factor Productivity, Anna Glazyrina

Agribusiness and Applied Economics

This study examines the importance of public research and development (R&D) expenditures and innovations (prices) to U S agricultural productivity employing panel vector error correction econometric technique Specifically, time-series and panel unit root tests, panel cointegration procedures, panel causality tests, and vector error correction model are used in the analysis. Empirical application to U S state-level data for 1960-2004 suggests positive and statistically significant influence of both supply-side drivers, in the form of public R&D expenditures, and demand-side drivers, in the form of innovations (prices), on total factor productivity growth.

North Dakota Beef Cow Operators: Identifying Current Management Practices And Factors That Influence Adoption Rates Of Best Management Practices Relating To Surface Water Pollution, Andrea Van Winkle

Agribusiness and Applied Economics

Best management practices are methods that have been determined to be the most effective and practical means of preventing or reducing pollution. Best Management Practices (BMPs) relating to surface water pollution abatement for North Dakota beef cow operations are of particular importance due to the importance of the agriculture industry in North Dakota. North Dakota has yet to address the use of voluntary BMPs to address potential surface water pollution regulations. Probit models were used to estimate the likelihood of North Dakota beef cow operators adopting specific production practices to reduce potential surface water pollution through the use of BMPs. …

Liberté, Égalité, Sororité: How Care Ethics Informs Social Justice, Maurice Hamington

Philosophy Faculty Publications and Presentations

Virginia Held has claimed that "there can be care without justice" but "there can be no justice without care." Alternatively, bell hooks has suggested that there can be "no love without justice." What is the relationship between justice and care? Does justice need an emotive, particularist, contextual aspect or is it fundamentally a universal and abstract concept?

Care ethics, as contemporary feminists have defined it, is only a quarter of a century old. When theorists were first struggling to distinguish this new ethical approach, some chose to sharply differentiate it from theories of justice. Now that care ethics has matured …

Nonlinear Time Dependence Of Dark Current In Charge-Coupled Devices, Justin Charles Dunlap, Erik Bodegom, Ralf Widenhorn

Physics Faculty Publications and Presentations

It is generally assumed that charge-coupled device (CCD) imagers produce a linear response of dark current versus exposure time except near saturation. We found a large number of pixels with nonlinear dark current response to exposure time to be present in two scientific CCD imagers. These pixels are found to exhibit distinguishable behavior with other analogous pixels and therefore can be characterized in groupings. Data from two Kodak CCD sensors are presented for exposure times from a few seconds up to two hours. Linear behavior is traditionally taken for granted when carrying out dark current correction and as a result, …

Dark Current In An Active Pixel Complementary Metal-Oxide-Semiconductor Sensor, Justin Charles Dunlap, William Christian Porter, Erik Bodegom, Ralf Widenhorn

Physics Faculty Publications and Presentations

We present an analysis of dark current from a complementary metal?oxide?semiconductor (CMOS) active pixels sensor with global shutter. The presence of two sources of dark current, one within the collection area of the pixel and another within the sense node, present complications to correction of the dark current. The two sources are shown to generate unique and characteristic dark current behavior with respect to varying exposure time, temperature, and/or frame rate. In particular, a pixel with storage time in the sense node will show a dark current dependence on frame rate and the appearance of being a ?stuck pixel? with …

Photoelectron Emission Control With Polarized Light In Plasmonic Metal Random Structures, Robert Campbell Word, Joseph Fitzgerald, Rolf Kӧnenkamp

Physics Faculty Publications and Presentations

The authors report on the possibility of switching the emission rate of photoelectrons by polarization changes in the plasmon excitation light. Photoelectron emission is strongly enhanced in the near-field of localized surface plasmons and occurs from areas with typical diameters of 20-70 nm. The underlying physical process involves excitation of a localized surface plasmon polariton with a femtosecond laser pulse, and a subsequent multi-photon photoemission process. The non-linearity of this process leads to a sharp polarization dependence that allows efficient switching of the emission. We demonstrate that a 90° polarization change can result in on/off ratios of ∼100 for electron …

Sounding Rocket Study Of Two Sequential Auroral Poleward Boundary Intensifications, M. R. Mella, Kristina A. Lynch, D. L. Hampton, H. Dahlgren, P. M. Kintner, M. Lessard, D. Lummerzheim, E. T. Lundberg, M. J. Nicolls, H. C. Stenbaek-Nielsen

Dartmouth Scholarship

The Cascades-2 sounding rocket was launched on 20 March 2009 at 11:04:00 UT from the Poker Flat Research Range in Alaska, and flew across a series of poleward boundary intensifications (PBIs). The rocket initially crosses a diffuse arc, then crosses the equatorward extent of one PBI (a streamer), and finally crosses the initiation of a separate PBI before entering the polar cap. Each of the crossings have fundamentally different in situ electron energy and pitch angle structure, and different ground optics images of visible aurora. It is found that the diffuse arc has a quasi-static acceleration mechanism, and the intensification …

A Threat Taxonomy For Mhealth Privacy, David Kotz

Dartmouth Scholarship

Networked mobile devices have great potential to enable individuals (and their physicians) to better monitor their health and to manage medical conditions. In this paper, we examine the privacy-related threats to these so-called \emphmHealth\/ technologies. We develop a taxonomy of the privacy-related threats, and discuss some of the technologies that could support privacy-sensitive mHealth systems. We conclude with a brief summary of research challenges.

Re-Interpreting The Past: Shifting Perspectives From A Commercial Archival Fond In The Bulgarian Historical Archive, Evguenia Davidova

International & Global Studies Faculty Publications and Presentations

This article offers a historiographical interpretation of an exceptionally rich personal archive; namely, fond Number 6: “Tŭrgovska kŭshta [Commercial Company] ‘Khristo P. Tŭpchileshtov’”, kept in Bŭlgarski istoricheski arkhiv (Bulgarian Historical Archive), Narodna Biblioteka (National Library) “Sv. Sv. Kiril i Metodiĭ” in Sofia. The analysis is organized around three issues: the biography of the archive’s founder; the acquisition of the archive by the National Library; and the ways the archival material has been interpreted in the Bulgarian historiography. More specifically, I am discussing the ideological motivation behind the arrangement of the documents and their multiple uses in the historical studies during …

Urban Water Demand Modeling: Review Of Concepts, Methods, And Organizing Principles, Heejun Chang, Lily House-Peters

Institute for Sustainable Solutions Publications and Presentations

In this paper, we use a theoretical framework of coupled human and natural systems to review the methodological advances in urban water demand modeling over the past 3 decades. The goal of this review is to quantify the capacity of increasingly complex modeling techniques to account for complex human and natural processes, uncertainty, and resilience across spatial and temporal scales. This review begins with coupled human and natural systems theory and situates urban water demand within this framework. The second section reviews urban water demand literature and summarizes methodological advances in relation to four central themes: (1) interactions within and …

Structuring Expert Input For A Knowledge-Based Approach To Watershed Condition Assessment For The Northwest Forest Plan, Usa, Sean N. Gordon, Kirsten Gallo

Institute for Sustainable Solutions Publications and Presentations

Assessments of watershed condition for aquatic and riparian species often have to rely on expert opinion because of the complexity of establishing statistical relationships among the many factors involved. Such expert-based assessments can be difficult to document and apply consistently over time and space. We describe and reflect on the process of developing a computer-based decision support application from expert judgments for assessing aquatic and riparian conditions over the 100,000 km2 managed by the US federal government under the Northwest Forest Plan. The decision support system helped structure and document the assessment process and provided consistency and transparency to the …
