Nineteenth-century America through the Eyes of John Gennadius

The aim of this article is to unfold and analyze the view of America held byJohn Gennadius [Ioannis Gennadios], one of the most important diplomats of nineteenthcenturyGreece. Having spent most of his life in England as a member of the Greek legation,which he served for more than 20 years, Gennadius was influenced by the ongoing Britishdiscussion of the “American miracle”. His perception was, however, fostered during twovisits to America, a professional one (1888) and a private one (1893-1894). He was involvedin American political life as the official negotiator of the Greek government, but alsoenjoyed the culture, witnessed the wealth and the galloping development and made manyacquaintances. All of this made an impression on him. He commented on the importanceof British influence on American civilization, acknowledged the material and intellectualprogress of its people and foresaw the potential of its thriving economy in world politics

Knowledge spillovers, absorptive capacity and growth: an industry-level analysis for OECD countries

Given the decline in growth momentum in the manufacturing sector in many OECD countries, the role of knowledge-based capital has emerged as a key driver for sustained growth. While empirical studies on estimating knowledge spillovers have usually been undertaken at the country level, the spillover effects can be more definitive only if the analysis is conducted at the industry-level. The effectiveness of international spillovers is conditional on recipient country’s absorptive capacity and this is an important component of the spillover mechanism that has not attracted significant attention so far. This paper therefore assesses the effect of spillovers in driving per capita output growth taking into account the role of absorptive capacity. Our main findings are first, the confirmation of the robust positive relationship between human capital and output growth for 14 OECD countries at industry level. Second, the gains from international spillover are conditional to the level of human capital and the degree of protection of intellectual property rights. Third, countries that improve absorptive capacity can potentially increase gains from spillovers via either trade or FDI (including vertical FDI). Finally, significant heterogeneity is found between high and low-tech industries. The former group is more effective in absorbing spillovers while the latter has failed to reach the critical level of technological advancement in order to absorb foreign and domestic knowledge

Knowledge spillovers and output per worker: an industry-level analysis for OECD countries

This study analyzes the impact of knowledge spillovers on output per worker at the industry level using a primal production function approach. The article makes three different contributions to the international spillovers literature: (1) it identifies trade related spillovers under alternative assumptions regarding the information transferred through imports; (2) it explores the importance of horizontal and vertical foreign direct investment (FDI) in knowledge spillovers; and (3) it looks at how institutional factors determine the impact of FDI-related spillovers on productivity. The main findings of the study are: (1) international knowledge spillover is an important driver of industry output per worker, and the magnitude of this spillover effect varies with alternative assumptions about the information content embodied in imports, while high technology industries benefit significantly more from import-related knowledge spillovers; and (2) the gains from FDI spillovers are primarily horizontal, but when institutional factors are considered, countries with stronger protection of intellectual property rights and a high “ease of doing business” tend to experience a substantial increase in the effectiveness of both horizontal and vertical FDI-related spillover

Reassessing the Greek National Schism of World War I: The Ideological Parameters

The National Schism that erupted in Greece during World War I has already been thoroughly analysed in the bibliography as a crisis of national unification, defined by geographical, political and socio economic criteria. The aim of this article is to move a step forward, to support that the National Schism might also be considered as an act in the broader and much older Greek ideological drama, that of the tantalising and incomplete “return” to the East via the European West. It is argued that the Schism, far from being a bipolar confrontation between supporters and opponents of Europe, did select from the East–West debate whatever arguments were necessary to invest military and political choices with a “deeper” meaning. Our approach focuses mostly on the rhetoric produced by the two opposing camps, the Venizelists and the anti-Venizelist block, from 1914 to 1922. It is, however, complemented by a retrospective presentation of the nineteenth-century debateover the Enlightenment and liberalism, on the one hand, and German idealism, on the other

Codifying and commodifying nature: Narratives on forest property rights and the implementation of tenure regularization policies in Northwestern Argentina

Environmental resource management requires negotiation among state and non-state actors with conflicting goals and different levels of influence. In northwestern Argentina, forest policy implementation is described as weak, due to governance structure and ambiguities in the law. We studied how policy actors’ attitudes and their positions in the forest governance network relate to the implementation of land tenure regularization in a context where land tenure regularization is at the core of struggles over environmental policies. We focused on the Chaco Salteño part of the Gran Chaco ecosystem, one of the world’s major deforestation frontiers. We argue that the presence of weak advocacy coalitions requires an analysis of agency to understand this policy process. Our policy network analysis revealed a lack of clear contrasting factions, due to a core–periphery structure. The core of the network brings together all core beliefs but not all of the most influential actors. Assessing network centrality and reputational influence enabled us to identify actors with exceptional agency. We contribute to the debates on advocacy coalitions and on land tenure by distinguishing between attitudes toward tenure regularization policies and their actual implementation in a context where actors have diverging interests and objectives

Spontaneous Polarisation Build up in a Room Temperature Polariton Laser

We observe the build up of strong (~50%) spontaneous vector polarisation in emission from a GaN-based polariton laser excited by short optical pulses at room temperature. The Stokes vector of emitted light changes its orientation randomly from one excitation pulse to another, so that the time-integrated polarisation remains zero. This behaviour is completely different to any previous laser. We interpret this observation in terms of the spontaneous symmetry breaking in a Bose-Einstein condensate of exciton-polaritons

A bio-inspired image coder with temporal scalability

We present a novel bio-inspired and dynamic coding scheme for static images. Our coder aims at reproducing the main steps of the visual stimulus processing in the mammalian retina taking into account its time behavior. The main novelty of this work is to show how to exploit the time behavior of the retina cells to ensure, in a simple way, scalability and bit allocation. To do so, our main source of inspiration will be the biologically plausible retina model called Virtual Retina. Following a similar structure, our model has two stages. The first stage is an image transform which is performed by the outer layers in the retina. Here it is modelled by filtering the image with a bank of difference of Gaussians with time-delays. The second stage is a time-dependent analog-to-digital conversion which is performed by the inner layers in the retina. Thanks to its conception, our coder enables scalability and bit allocation across time. Also, our decoded images do not show annoying artefacts such as ringing and block effects. As a whole, this article shows how to capture the main properties of a biological system, here the retina, in order to design a new efficient coder.Comment: 12 pages; Advanced Concepts for Intelligent Vision Systems (ACIVS 2011
