Military and government applications of human-machine communication by voice.

This paper describes a range of opportunities for military and government applications of human-machine communication by voice, based on visits and contacts with numerous user organizations in the United States. The applications include some that appear to be feasible by careful integration of current state-of-the-art technology and others that will require a varying mix of advances in speech technology and in integration of the technology into applications environments. Applications that are described include (1) speech recognition and synthesis for mobile command and control; (2) speech processing for a portable multifunction soldier's computer; (3) speech- and language-based technology for naval combat team tactical training; (4) speech technology for command and control on a carrier flight deck; (5) control of auxiliary systems, and alert and warning generation, in fighter aircraft and helicopters; and (6) voice check-in, report entry, and communication for law enforcement agents or special forces. A phased approach for transfer of the technology into applications is advocated, where integration of applications systems is pursued in parallel with advanced research to meet future needs.

Entre a saúde e a repressão - políticas públicas na região da \'Cracolândia\' SP

Um território, uma substância e três Políticas Públicas atuando sobre uma mesma população. O trabalho tem como objetivo oferecer uma análise das Políticas Públicas para usuários de Crack instaladas no território da \"Cracolândia\" paulista, localizado no Bairro da Luz (São Paulo-SP). A criação do Programa Crack É Possível Vencer em 2010, articulada à emergência de discursos que especulavam sobre uma possível epidemia e crescente interesse dos meios de comunicação sobre a população usuária, abriu a possibilidade de criação de espaços institucionais para que o Estado intervisse sobre os usuários de crack. Dentro desse contexto, e articuladas a esse Programa do Governo Federal, surgem duas Políticas Públicas: Programa Recomeço de gestão Estadual e Programa De Braços Abertos de gestão Municipal. As ações dessas duas políticas durante os anos 2014 e 2015 constituem o foco do recorte empírico do presente trabalho. O esforço de pesquisa foi no sentido de investigar como as novas Políticas Públicas que se propunham a operar no campo da Saúde Pública e do cuidado iriam se materializar no território, como o discurso institucional iria se traduzir enquanto práticas. Em especial, interessava observar se as novas ações iriam inibir o movimento histórico de higienização do território e expulsão dos usuários. Visando contemplar na pesquisa ponto de vistas, experiências e discursos que não se limitassem ao relato institucional, foram utilizadas três fontes de dados: pesquisas realizadas na região, reportagens e documentos lançados pela mídia e pesquisa de campo. Foi realizada uma leitura e descrição detalhada de três etnografias feitas na região, com o objetivo de comparar as intervenções passadas com o contexto atual; através da análise de duas personagens midiáticas, que surgiram nos meios de comunicação em 2015, traçou-se a imagem do usuário de crack que é veiculada socialmente. E através de observação participante no território, foram descritos os eventos acontecidos durante o período de tempo delimitado, distribuídos em três eixos: Saúde, Repressão e Resistência. À partir desse itinerário de pesquisa, foi elaborada uma discussão que pontua as diferenças entre o discurso e a prática. Dentre as considerações finais, destaca-se a diferença dos modelos de tratamentos propostos pelas Políticas Públicas internação e Redução de Danos e a forma como essa disputa se materializa no cuidado aos usuários de crack. Embora tenha ocorrido um crescimento de ofertas de saúde, também ocorreu um aumento progressivo no número de agentes de segurança e equipamentos de vigilância na Cracolândia, instaurando aquilo que é chamado de Confinamento dos usuários, composto de práticas de limpeza das ruas, retirada de bens dos usuários e filmagem dos usuários. Uma estratégia de gentrificação foi detectada e descrita, ação cujo protagonista é uma empresa de seguros que, no período delimitado, se mostrou excessivamente atuante no território, mobilizando as ações estatais. E por fim, também foram descritas as ações de resistência dos usuários frente à criação das Políticas Públicas e das outras formas de intervenção estatal, ações tais como a construção das favelinhas e a atuação dos profissionais e militantes da região. Espera-se que esse trabalho contribua para uma maior compreensão da Cracolândia paulista e forneça subsídios para que melhores Políticas Públicas sejam criadas no território.

Evidence for non-conservative current-induced forces in the breaking of Au and Pt atomic chains

This experimental work aims at probing current-induced forces at the atomic scale. Specifically it addresses predictions in recent work regarding the appearance of run-away modes as a result of a combined effect of the non-conservative wind force and a ‘Berry force’. The systems we consider here are atomic chains of Au and Pt atoms, for which we investigate the distribution of break down voltage values. We observe two distinct modes of breaking for Au atomic chains. The breaking at high voltage appears to behave as expected for regular break down by thermal excitation due to Joule heating. However, there is a low-voltage breaking mode that has characteristics expected for the mechanism of current-induced forces. Although a full comparison would require more detailed information on the individual atomic configurations, the systems we consider are very similar to those considered in recent model calculations and the comparison between experiment and theory is very encouraging for the interpretation we propose.

Essays in dynamic optimal taxation: working experience, unemployment scarring and poverty

This thesis investigates the design of optimal tax systems in dynamic environments. The first essay characterizes the optimal tax system where wages depend on stochastic shocks and work experience. In addition to redistributive and efficiency motives, the taxation of inexperienced workers depends on a second-best requirement that encourages work experience, a social insurance motive and incentive effects. Calibrations using U.S. data yield higher expected optimal marginal income tax rates for experienced workers for most of the inexperienced workers. They confirm that the average marginal income tax rate increases (decreases) with age when shocks and work experience are substitutes (complements). Finally, more variability in experienced workers' earnings prospects leads to increasing tax rates since income taxation acts as a social insurance mechanism. In the second essay, the properties of an optimal tax system are investigated in a dynamic private information economy where labor market frictions create unemployment that destroys workers' human capital. A two-skill type model is considered where wages and employment are endogenous. I find that the optimal tax system distorts the first-period wages of all workers below their efficient levels which leads to more employment. The standard no-distortion-at-the-top result no longer holds due to the combination of private information and the destruction of human capital. I show this result analytically under the Maximin social welfare function and confirm it numerically for a general social welfare function. I also investigate the use of a training program and job creation subsidies. The final essay analyzes the optimal linear tax system when there is a population of individuals whose perceptions of savings are linked to their disposable income and their family background through family cultural transmission. Aside from the standard equity/efficiency trade-off, taxes account for the endogeneity of perceptions through two channels. First, taxing labor decreases income, which decreases the perception of savings through time. Second, taxation on savings corrects for the misperceptions of workers and thus savings and labor decisions. Numerical simulations confirm that behavioral issues push labor income taxes upward to finance saving subsidies. Government transfers to individuals are also decreased to finance those same subsidies.

Disappearing government bond spreads in the eurozone - Back to normal? CEPS Working Document No. 396, May 2014

Since the announcement of the Outright Monetary Transactions (OMT) programme by Mario Draghi, President of the ECB, in 2012, the government bond spreads began a strong decline. This paper finds that most of this decline is due to the positive market sentiments that the OMT programme has triggered and is not related to underlying fundamentals, such as the debt-to-GDP ratios or the external debt position that have continued to increase in most countries. The authors even argue that the market’s euphoria may have gone too far in taking into account the same market fundamentals. They conclude with some thoughts about the future governance of the OMT programme.

Germany's energy transformation: difficult beginnings. OSW Report, March 2013

Initiated in May 2011, several months after the Fukushima nuclear disaster, Germany’s energy transformation (Energiewende) has been presented as an irrevocable plan, and – due to the speed of change required – it represents a new quality in Germany’s energy strategy. Its main objectives include: nuclear energy being phased out by 2022, the development of renewable energy sources (OZE), the expansion of transmission networks, the construction of new conventional power plants and an improvement in energy efficiency.The cornerstone of the strategy is the development of renewable energy. Under Germany's amended renewable energy law, the proportion of renewable energy in electricity generation is supposed to increase steadily from the current level of around 20% to approximately 38% in 2020. In 2030, renewable energy is expected to account for 50% of electricity generation. This is expected to increase to 65% in 2040 and to as much as 80% in 2050. The impact of the Energiewende is not limited to the sphere of energy supplies. In the medium and long term, it will change not only to the way the German economy operates, but also the functioning of German society and the state. Facing difficulties with the expansion of transmission networks, the excessive cost of building wind farms, and problems with the stability of electricity supplies, especially during particularly cold winters, the federal government has so far tended to centralise power and limit the independence of the German federal states with regard to their respective energy policies, justifying this with the need for greater co-ordination. The Energiewende may also become the beginning of a "third industrial revolution", i.e. a transition to a green economy and a society based on sustainable development. This will require a new "social contract" that will redefine the relations between the state, society and the economy. Negotiating such a contract will be one of the greatest challenges for German policy in the coming years.

The Ukrainian government's strategy towards the opposition. OSW Commentary No. 47, 2011-09-02

In recent months in Ukraine, there has been a toughening of measures targeted at opposition leaders, in particular the former Prime Minister Yulia Tymoshenko and the former interior minister Yuri Lutsenko. These two have been charged with abuses of office when in power. The way in which the criminal investigations are being conducted shows that these measures are actually meant to prevent the two politicians from conducting regular political activities, or at least to make this practically impossible for them. These actions are an element of the Party of Regions’ long-term strategy, as it tries during the pre-election period to eliminate Yulia Tymoshenko from political life and weaken or even destroy her powerbase. Similar measures, although to a more limited extent, are being taken against other opposition groups. These actions are leading to the lowering of democratic standards in Ukraine, although these are still much higher than in Belarus or Russia; this has been proved, among other things, by the militia’s more restrained behaviour towards the protesters, and the fact that abuses of the law during the current investigations have not yet slipped into actual violations. The Ukrainian opposition is fragmented and disorganised; even the Yulia Tymoshenko Bloc is unable to stage a major campaign in defence of its leader. This allows the authorities to feel free to tighten their policy towards the opposition.

Riding or Reaping the Whirlwind? An Account of the EU’s Engagement with Insecurity in Northern Nigeria. EU Diplomacy Paper No. 9, November 2014

The relations of the European Union (EU) with Africa are increasingly spreading beyond the domain of humanitarian and development cooperation. The continent’s growing potential is producing vast webs of interlinkages in the realms of energy and commerce, among others. At the same time, such interdependencies bring with them increased vulnerabilities to insecurity on the continent. Nigeria exemplifies such a dilemma. The country has just taken the top spot as Africa’s largest economy. Of late, however, violent Islamic extremism ravages the north of the country, threatening the stability of one of Europe’s foremost energy suppliers and a growing trade partner. Thus, this paper sets out to uncover the EU’s response to such a crisis, as well as examining the factors lying behind this response. While the study argues that the issue is potentially ‘Europeaniz-able’ from a member state perspective, deep engagement is seen to be held back by the absence of an effective entry point for securitization with this important ally, as well as the intractability of the EU’s purported multi-functional approach to the idiosyncrasies of the conflict in question, in which not only transnational terrorist groups, but also the central government are centrally implicated in deepening insecurity.

Education and Social Protection Systems in Southern and Eastern Mediterranean Countries. MEDPRO Technical Report No. 20/January 2013

This report assesses the current status of the education and social protection systems in 11 southern and eastern Mediterranean countries. It compares these countries using various education indicators and attempts to highlight the main differences in the social protection systems among the countries using qualitative analysis. The report finds that despite the differences among the countries, they share a common feature: when measured by the UN Development Programme’s Human Development Index (HDI), their inequality-adjusted values are significantly lower than their HDI values and ranks when not taking inequality into account. Nevertheless, significant improvements have been achieved in all the quantitative indicators for education, while the qualitative performance is still modest in the majority of the countries studied. As to the social protection aspect, the research reveals that various social protection programmes are being adopted in the 11 countries. As most of their financing is covered by government budgets, however, this places a high fiscal burden on them. Yet few of the countries (Turkey being the most notable) are trying to improve the sustainability of their social insurance schemes.

Saving the Banks: The Political Economy of Bailouts. CES Papers - Open Forum #8, 2012

How much leeway did governments have in designing bank bailouts and deciding on the height of intervention during the 2007-2009 financial crisis? This paper analyzes comparatively what explains government responses to banking crises. Why does the type of intervention during financial crises vary to such a great extent across countries? By analyzing the variety of bailouts in Europe and North America, we will show that the strategies governments use to cope with the instability of financial markets does not depend on economic conditions alone. Rather, they take root in the institutional and political setting of each country and vary in particular according to the different types of business-government relations banks were able to entertain with public decision-makers. Still, “crony capitalism” accounts overstate the role of bank lobbying. With four case studies of the Irish, Danish, British and French bank bailout, we show that countries with close one-on-one relationships between policy-makers and bank management tended to develop unbalanced bailout packages, while countries where banks have strong interbank ties and collective negotiation capacity were able to develop solutions with a greater burden sharing from private institutions.

TTIP and Public Procurement: Going beyond the tip of the iceberg. CEPS Policy Brief No. 339, March 2016

Trade negotiations involving international public procurement rules are on the rise, stimulating a growing interest in having a clear picture of the economic stakes involved, including the current level of international openness. A recent paper published by the European Centre for International Political Economy (Messerlin, 2016) made an attempt to provide a range of estimates for the EU and the US and found relatively low rates of import penetration. This analytical approach, however, looked only at the ‘tip of the procurement iceberg’, as the data used covered primarily only one modality of international procurement (direct cross-border), which is not the main avenue for international government procurement. Other modalities, such as procurement from foreign subsidiaries established in Europe, account for much more. Such an approach therefore ignores the main modalities through which foreign firms win EU contracts. Once these other main procurement modalities are taken into account, EU openness in procurement is much higher. Comparable data across all modalities do not yet exist for the US, but we do have clear evidence that the US has introduced the largest number of protectionist procurement measures since 2008 affecting all modalities for international procurement. Against this background, this Policy Brief makes four basic points: i. Public procurement is a key area of trade negotiations, and TTIP is no exception to this rule. ii. The existing levels of openness in procurement markets need to be assessed across all three main procurement modalities and not based only on direct cross-border procurement, which is not the main procurement avenue. According to this comprehensive metric, the EU market already has a high foreign participation rate, including by US companies. iii. Unfortunately, similar data do not exist for the US market. But there is growing evidence of discriminatory measures introduced in recent years, which impede the ability of EU firms to compete on a level-playing field in US procurement markets. iv. The importance of procurement as a key negotiating area requires better data and a greater analytical engagement.

Maps (pdf) and raster images (tif) of predicted rural land cover suitability under current (2010) conditions and future climate scenarios

This study projects land cover probabilities under climate change for corn (maize), soybeans, spring and winter wheat, winter wheat-soybean double cropping, cotton, grassland and forest across 16 central U.S. states at a high spatial resolution, while also taking into account the influence of soil characteristics and topography. The scenarios span three oceanic-atmospheric global circulation models, three Representative Concentration Pathways, and three time periods (2040, 2070, 2100). As climate change intensifies, the suitable area for all six crops display large northward shifts. Total suitable area for spring wheat, followed by corn and soybeans, diminish. Suitable area for winter wheat and for winter wheat-soybean double-cropping expand northward, while cotton suitability migrates to new, more northerly, locations. Suitability for forest intensifies in the south while yielding to crops in the north; grassland intensifies in the western Great Plains as crop suitability diminishes. To maintain current broad geographic patterns of land use, large changes in the thermal response of crops such as corn would be required. A transition from corn-soybean to winter wheat-soybean doubling cropping is an alternative adaptation.
