Does the distribution of income within a country become more equal as it grows richer? This paper uses plausibly exogenous variations in trade-weighted world income and international oil price shocks as instruments for within-country variations in countries real GDP per capita to examine this issue for a large sample of advanced and developing countries. Our findings indicate that increases in national income have a significant moderating effect on income inequality: a one percent increase in real GDP per capita, on average, reduces the Gini coefficient by around 0.08 percentage points, a result that is robust across income levels, different time horizons, and alternative estimation techniques. From a policy perspective, our results suggest that education policies that promote equity and help individuals continue on to higher levels of education could help reduce income inequality.
We examine the effects that international commodity price shocks have on external debt using panel data for a world sample of 93 countries spanning the period 1970-2007. Our main finding is that positive commodity price shocks lead to a significant reduction in the level of external debt in democracies, but to no significant reduction in the level of external debt in autocracies. To explain this result, we show that positive commodity price shocks lead to a statistically significant and quantitatively large increase in total government expenditures in autocracies. In democracies on the other hand government expenditures did not increase significantly. We also document that following positive windfalls from international commodity price shocks the risk of default on external debt decreased in democracies, but increased significantly in autocracies.
We examine the effect that revenue windfalls from international commodity price shocks have on sovereign bond spreads using panel data for 30 emerging market economies during the period 1997-2007. Our main finding is that positive commodity price shocks lead to a significant reduction in the sovereign bond spread in democracies, but to a significant increase in the spread in autocracies. To explain our finding we show that, consistent with the political economy literature on the resource curse, revenue windfalls from international commodity price shocks significantly increased real per capita GDP growth in democracies, while in autocracies GDP per capita growth decreased.
How effective was public investment in stimulating the Japanese economy during the economic stagnation of the 1990s? Using a dataset of regional public investment spending, we find that investment multipliers were higher than for public consumption, although they were relatively low and declining over time. The paper also finds that the effectiveness of economic infrastructure investment, implemented mainly by the central government, is lower than that of social investment mostly undertaken by local governments. These results suggest that while public investment may yield higher output effects than other spending, its effectiveness depends upon its composition, the level of government implementation, and supply side factors.
We examine the effects that variations in the international food prices have on democracy and intra-state conflict using panel data for over 120 countries during the period 1970-2007. Our main finding is that in Low Income Countries increases in the international food prices lead to a significant deterioration of democratic institutions and a significant increase in the incidence of anti-government demonstrations, riots, and civil conflict. In the High Income Countries variations in the international food prices have no significant effects on democratic institutions and measures of intra-state conflict. Our empirical results point to a significant externality of variations in international food prices on Low Income Countries' social and political stability.
This paper examines the effect that windfalls from international commodity price booms have on net foreign assets in a panel of 145 countries during the period 1970-2007. The main finding is that windfalls from international commodity price booms lead to a significant increase in net foreign assets, but only in countries that are homogeneous. In polarized countries, net foreign assets significantly decreased. To explain this asymmetry, the paper shows that in polarized countries commodity windfalls lead to large increases in government spending, political corruption, and the risk of expropriation, with no overall effect on GDP per capita growth. The paper's findings are consistent with theoretical models of the current account that have a built-in voracity effect.

Our Unsustainable Life: Why We Can't Have Everything We Want With the concept of the Imperial Mode of Living, Brand and Wissen highlight the fact that capitalism implies uneven development as well as a constant and accelerating universalisation of a Western mode of production and living. The logic of liberal markets since the 19thCentury, and especially since World War II, has been inscribed into everyday practices that are usually unconsciously reproduced. The authors show that they are a main driver of the ecological crisis and economic and political instability. The Imperial Mode of Living implies that people's everyday practices, including individual and societal orientations, as well as identities, rely heavily on the unlimited appropriation of resources; a disproportionate claim on global and local ecosystems and sinks; and cheap labour from elsewhere. This availability of commodities is largely organised through the world market, backed by military force and/or the asymmetric relations of forces as they have been inscribed in international institutions. Moreover, the Imperial Mode of Living implies asymmetrical social relations along class, gender and race within the respective countries. Here too, it is driven by the capitalist accumulation imperative, growth-oriented state policies and status consumption. The concrete production conditions of commodities are rendered invisible in the places where the commodities are consumed. The imperialist world order is normalized through the mode of production and living.
During the past two decades, there has emerged a growing need to reconsider the objects, axioms and perspectives of writing music history. A certain suspicion towards Francois Lyotard’s grand narratives, as a sign of what he diagnosed as our ’postmodern condition’, has become more or less an established and unquestioned point of departure among historians. This suspicion, at its most extreme, has led to a radical conclusion of the ’end of history’ in the work of postmodern scholars such as Jean Baudrillard and Francis Fukuyama. The contributors to Critical Music Historiography take a step back and argue that the radical view of the ’impossibility of history’, as well as the unavoidable ideology of any history, are counter-productive points of departure for historical scholarship. It is argued that metanarratives in history are still possible and welcome, even if their limitations are acknowledged. Foucault, Lyotard and others should be taken into account but systematized viewpoints and methods for a more critical and multi-faceted re-evaluation of the past through research are needed. As to the metanarratives of music history, they must avoid the pitfalls of evolutionism, hagiography, and teleology, all hallmarks of traditional historiography. In this volume the contributors put these methods and principles into practice. The chapters tackle under-researched and non-conventional domains of music history as well as rethinking older historiographical concepts such as orientalism and nationalism, and consequently introduce new concepts such as occidentalism and transnationalism. The volume is a challenging collection of work that stakes out a unique territory for itself among the growing body of work on critical music history.
Johann Sebastian Bach's works are often classified along the lines of "sacred" versus "secular." While this distinction is fraught with problems, it seems to provide a useful way to distinguish between Bach's vocal works for the liturgy and those that were written to honor courts and members of the nobility. But even there, the lines cannot be drawn that clearly. The political and social systems of Bach's time relied on religion as an ideological foundation and public displays of political power almost always included religious rituals and thus required some form of sacred music. Social constructs, such as class and gender, were also embedded in religious frameworks. The book analyzes public manifestations of the social order during Bach's time in large-scale celebrations, processions, public performances, and visual displays. By analyzing selected cantatas, the book explores how Bach's music functioned as an agent of affective communication within rituals, such as the installation of the town council, and as a place where socio-political norms were perpetuated and-in a few cases-even challenged"--
This interdisciplinary and international volume provides a critical analysis of the power to police as a basic technology of modern government found in a vast array of sites of governance, including not only the state, but also the household, the factory, the military, and—most recently—the global realm of war, police actions, and peace keeping.
A history of genealogical knowledge-making strategies in the early modern world. In The Maker of Pedigrees, Markus Friedrich explores the complex and fascinating world of central European genealogy practices during the Baroque era. Drawing on archival material from a dozen European institutions, Friedrich reconstructs how knowledge about noble families was created, authenticated, circulated, and published. Jakob Wilhelm Imhoff, a wealthy and well-connected patrician from Nuremberg, built a European community of genealogists by assembling a transnational network of cooperators and informants. Friedrich uses Imhoff as a case study in how knowledge was produced and disseminated during the 17th and 18th centuries. Family lineages were key instruments in defining dynasties, organizing international relations, and structuring social life. Yet in the early modern world, knowledge about genealogy was cumbersome to acquire, difficult to authenticate, and complex to publish. Genealogy's status as a source of power and identity became even more ambivalent as the 17th century wore on, as the field continued to fragment into a plurality of increasingly contradictory formats and approaches. Genealogy became a contested body of knowledge, as a heterogeneous set of actors—including aristocrats, antiquaries, and publishers—competed for authority. Imhoff was closely connected to all of the major genealogical cultures of his time, and he serves as a useful prism through which the complex field of genealogy can be studied in its bewildering richness.
This book presents a compilation of articles on the subject of game studies written over the last ten years. These texts reflect a decade of research in European computer game studies from a theoretical perspective that combines philosophy, cultural studies, visual studies, and media studies in a way that is unique to a specific type of media theory developed in Germany over the last thirty years. This theory differs quite significantly from media studies as usually conceived in Anglo-American academia, providing new perspectives that are rooted in continental philosophical traditions ranging from phenomenology to post-structuralism and newer forms of “presence studies” in aesthetic theory. The book provides (1) an introduction to a continental approach to game philosophy; (2) an aesthetic theory of computer games rooted in concepts of performativity and epistemology; and (3) an introduction to an interdisciplinary approach to game studies that is based on philosophical perspectives on the subject matter.
Airspace surveillance is one of the classic applications of radar technology. Existing systems are focused on large-scale surveillance of commercial airspace. This research presents a prototype of a small, mobile, passive radar system that for example can be used to monitor aircraft and UAVs in the airspace over maritime borders. The system is based on a coherent, software defined receiving system for data acquisition. The signal processing is subsequently performed in the digital domain. The paper gives an introduction to all the required fundamentals and all the relevant steps of signal processing are shown, starting from digital beamforming, through the generation of the range Doppler matrices, all the way to the tracking of targets using Kalman filters. Furthermore, a novel system for the detection of transmitter locations is presented, which allows the use of such a system in previously unknown scenarios. Finally, measurements are presented to show what such a system can achieve under real world conditions.
For quite some time, in systems and software design, security only came as a second thought or even as a nice-to-have add-on. However, since the breakthrough of the Internet as a virtual backbone for electronic commerce and similar applications, security is now recognized as a fundamental requirement. This book presents a systematic security improvement approach based on the pattern paradigm. The author first clarifies the key concepts of security patterns, defines their semantics and syntax, demonstrates how they can be used, and then compares his model with other security approaches. Based on the author's model and best practice in security patterns, security novices are now in a position to understand how security experts solve problems and can basically act like them by using the patterns available as building blocks for their designs.

Software programs are formal entities with precise meanings independent of their programmers, so the transition from ideas to programs necessarily involves a formalisation at some point. The first part of this graduate-level introduction to formal methods develops an understanding of what constitutes formal methods and what their place is in Software Engineering. It also introduces logics as languages to describe reasoning and the process algebra CSP as a language to represent behaviours. The second part offers specification and testing methods for formal development of software, based on the modelling languages CASL and UML. The third part takes the reader into the application domains of normative documents, human machine interfaces, and security. Use of notations and formalisms is uniform throughout the book. Topics and features: Explains foundations, and introduces specification, verification, and testing methods Explores various application domains Presents realistic and practical examples, illustrating concepts Brings together contributions from highly experienced educators and researchers Offers modelling and analysis methods for formal development of software Suitable for graduate and undergraduate courses in software engineering, this uniquely practical textbook will also be of value to students in informatics, as well as to scientists and practical engineers, who want to learn about or work more effectively with formal theories and methods.

Being diagnosed with a serious illness is often followed by despair and helplessness. Those affected wonder how their illness will affect their everyday lives and the rest of their lives. Dr. Freimann, who was diagnosed with multiple sclerosis at a young age after experiencing various unexplained symptoms, also found himself in this situation. In this work, the author reviews his life to date, most of which he has now spent with the disease.
Questions relating to (im)migration are among the most heated topics on both sides of the Atlantic. Western societies have changed dramatically because of large-scale immigration in the last decades. Christians are also engaged in the discussion, attempting to find direction from the biblical texts. Overwhelmingly, persons in leading positions (both in the secular world and in churches and faith-based organizations) support the concept of “welcoming the stranger.” The Bible is seen by them as urging us to open the borders as wide as we can. In the broader population, however, reservations remain. This book, written by a Bible professor who has witnessed mass-migration first-hand, both in Europe and in the U.S., and who has been a migrant himself for over twenty years, attempts to step back and look at the whole of the complex biblical witness, instead of cherry-picking passages that further a specific agenda. It also looks at the salient data on the ground, in the fields of psychology, demography, economy, and security—data that can no longer be ignored when trying to apply the Bible in a responsible way. The book demonstrates the shortcomings of the vast majority of biblical and theological publications on the issue of (im)migration and presents a comprehensive argument for the use of wisdom and caution, and against short-sighted and emotionally driven policies supporting open borders.
An argument against the role of visual imagination in reasoning that proposes a spatial theory of human thought, supported by empirical and computational evidence. Many scholars believe that visual mental imagery plays a key role in reasoning. In Space to Reason, Markus Knauff argues against this view, proposing that visual images are not relevant for reasoning and can even impede the process. He also argues against the claim that human thinking is solely based on abstract symbols and is completely embedded in language. Knauff proposes a third way to think about human reasoning that relies on supramodal spatial layout models, which are more abstract than pictorial images and more concrete than linguistic representations. He argues that these spatial layout models are at the heart of human thought, even thought about nonspatial relations in the world. For Knauff the visual images that we so often associate with reasoning are only in the foreground of conscious experience. Behind the images, the actual logical work is carried out by reasoning-specific operations on these spatial layout models. Knauff also offers a solution to the problem of indeterminacy in human reasoning, introducing the notion of a preferred layout model, which is one layout model among others that has the best chance of being mentally constructed and thus guides the further process of thought. Knauff's "space to reason" theory covers the functional, the algorithmic, and the implementational level of analysis and is corroborated by psychological experiments, functional brain imaging, and computational modeling.
A cutting†‘edge media history on a perennially fascinating topic, which attempts to answer the crucial question: Who is in charge, the servant or the master?†‹ Though classic servants like the butler or the governess have largely vanished, the Internet is filled with servers: web, ftp, mail, and others perform their daily drudgery, going about their business noiselessly and unnoticed. Why then are current†‘day digital drudges called servers? Markus Krajewski explores this question by going from the present back to the Baroque to study historical aspects of service through various perspectives, be it the servants’ relationship to architecture or their function in literary or scientific contexts. At the intersection of media studies, cultural history, and literature, this work recounts the gradual transition of agency from human to nonhuman actors to show how the concept of the digital server stems from the classic role of the servant.
Doctoral Thesis / Dissertation from the year 2008 in the subject Electrotechnology, grade: summa cum laude, Technical University of Ilmenau, language: English, abstract: This thesis deals with Experimental Channel Characterisation and its performance limits in real propagation environments. This includes recording of the multidimensional wideband channel matrix by using a MIMO channel sounder and antenna arrays at both sides of the link. High-resolution parameter estimation is finally applied to characterise the channel in terms of DoD, DoA, TDoA, and complex polarimetric path weights. The quality of these estimates in “real world” scenarios is degraded by several impairments of the practical antenna arrays and the measurement system used. The resulting estimation quality limits are investigated in detail by simulations and measurements. The entire processing chain is analysed in terms of possible error sources. To this end, measurement system impairments, antenna array calibration errors as well as limitations of the radio channel model comprising two parts: specular like reflections (SC) and distributed diffuse scattering (DMC) applied by the high-resolution parameter estimation procedure are investigated. Moreover, consequences of using these results to deduce and parameterise geometry based channel models are demonstrated. The contributions of this thesis are of interest for researchers dealing with high-resolution parameter estimation and channel modelling and can be summarised as follows: • the efficient and accurate radiation pattern modelling of antenna arrays, • the powerful performance evaluation framework for practical antenna arrays, • the exposure of consequence of modelling errors on parameter estimation, • and the demonstration of overall limitations of Experimental Channel Characterisation.
Whether it be as translucent sheets, broadly stretched membranes, and inflated foil cushions or in graceful, organic curves, architecture today is utilizing plastics in the most disparate forms and for a wide variety of purposes. Innovative technical developments are constantly improving its material properties; at the same time, there is a growing new awareness of its potential as a construction material. While plastics used to be employed primarily as an inexpensive variant on traditional building materials, they are increasingly regarded in the construction world today as a serious and viable alternative, be it as supporting structures, roofs, facades, or elements of interior design and decoration. Thanks in large part to this inherent self-sufficiency, plastics are currently enjoying an unprecedented surge in popularity, even among the international architectural avant-garde – as multiwall sheets or corrugated, fiber-reinforced panels, or as filling between glass panes. And the new generation of ecological bioplastics also pays tribute to the debate on sustainability, ridding plastics of their lingering reputation as environmental offenders. From the history of plastics and membranes in architecture to their material properties and requirements in construction and design, the Plastics and Membranes Construction Manual cuts to the chase, providing the kind of solid and comprehensive overview of the subject that readers have come to expect from the Im DETAIL series. Selected project examples round off the reference work and make it indispensable for the day-to-day life of the professional planner and for every architecture library.
