Self-Learning Embedded System for Object Identification in Intelligent Infrastructure Sensors

The emergence of new horizons in the field of travel assistant management leads to the development of cutting-edge systems focused on improving the existing ones. Moreover, new opportunities are being also presented since systems trend to be more reliable and autonomous. In this paper, a self-learning embedded system for object identification based on adaptive-cooperative dynamic approaches is presented for intelligent sensor’s infrastructures. The proposed system is able to detect and identify moving objects using a dynamic decision tree. Consequently, it combines machine learning algorithms and cooperative strategies in order to make the system more adaptive to changing environments. Therefore, the proposed system may be very useful for many applications like shadow tolls since several types of vehicles may be distinguished, parking optimization systems, improved traffic conditions systems, etc.

The α chain of laminin-1 is independently secreted and drives secretion of its β- and γ-chain partners

A mammalian recombinant strategy was established to dissect rules of basement membrane laminin assembly and secretion. The α-, β-, and γ-chain subunits of laminin-1 were expressed in all combinations, transiently and/or stably, in a near-null background. In the absence of its normal partners, the α chain was secreted as intact protein and protein that had been cleaved in the coiled-coil domain. In contrast, the β and γ chains, expressed separately or together, remained intracellular with formation of ββ or βγ, but not γγ, disulfide-linked dimers. Secretion of the β and γ chains required simultaneous expression of all three chains and their assembly into αβγ heterotrimers. Epitope-tagged recombinant α subunit and recombinant laminin were affinity-purified from the conditioned medium of αγ and αβγ clones. Rotary-shadow electron microscopy revealed that the free α subunit is a linear structure containing N-terminal and included globules with a foreshortened long arm, while the trimeric species has the typical four-arm morphology of native laminin. We conclude that the α chain can be delivered to the extracellular environment as a single subunit, whereas the β and γ chains cannot, and that the α chain drives the secretion of the trimeric molecule. Such an α-chain-dependent mechanism could allow for the regulation of laminin export into a nascent basement membrane, and might serve an important role in controlling basement membrane formation.

The influence of depicted illumination on brightness

The striking illusions produced by simultaneous brightness contrast generally are attributed to the center-surround receptive field organization of lower order neurons in the primary visual pathway. Here we show that the apparent brightness of test objects can be either increased or decreased in a predictable manner depending on how light and shadow are portrayed in the scene. This evidence suggests that perceptions of brightness are generated empirically by experience with luminance relationships, an idea whose implications we pursue in the accompanying paper.

Everything in di Dark Muss Come to Light: A Postcolonial Investigation of the Practice of Extra Lessons at the Secondary Level in Jamaica's Education System

Despite the vast research examining the evolution of Caribbean education systems, little is chronologically tied to the postcolonial theoretical perspectives of specific island-state systems, such as the Jamaican education system and its relationship with the underground shadow education system. This dissertation study sought to address the gaps in the literature by critically positioning postcolonial theories in education to examine the macro- and micro-level impacts of extra lessons on secondary education in Jamaica. The following postcolonial theoretical (PCT) tenets in education were contextualized from a review of the literature: (a) PCT in education uses colonial discourse analysis to critically deconstruct and decolonize imperialistic and colonial representations of knowledge throughout history; (b) PCT in education uses an anti-colonial discursive framework to re-position indigenous knowledge in schools, colleges, and universities to challenge hegemonic knowledge; (c) PCT in education involves the "unlearning" of dominant, normative ideologies, the use of self-reflexivity, and deconstruction; and (d) PCT in education calls for critical pedagogical approaches that reject the banking concept of education and introduces inclusive pedagogy to facilitate "the passage from naïve to critical transitivity" (Freire, 1973, p. 32). Specifically, using a transformative mixed-methods design, grounded and informed by a postcolonial theoretical lens, I quantitatively uncovered and then qualitatively highlighted how if at all extra lessons can improve educational outcomes for students at the secondary level in Jamaica. Accordingly, the quantitative data was used to test the hypotheses that the practice of extra lessons in schools is related to student academic achievement and the practice of critical-inclusive pedagogy in extra lessons is related to academic achievement. The two-level hierarchical linear model analysis revealed that hours spent in extra lessons, average household monthly income, and critical-inclusive pedagogical tents were the best predictors for academic achievement. Alternatively, the holistic multi-case study explored how extra-lessons produces increased academic achievement. The data revealed new ways of knowledge construction and critical pedagogical approaches to galvanize systemic change in secondary education. Furthermore, the data showed that extra lessons can improve educational outcomes for students at the secondary level if the conditions for learning are met. This study sets the stage for new forms of knowledge construction and implications for policy change.

Cerámica e Islamización: el origen de la tradición alfarera

La cerámica es uno de los testimonios arqueológicos más abundantes y reconocibles. Generalmente se le atribuye un importante valor histórico en tanto que informa sobre procesos socioeconómicos de gran importancia y constituye un significativo referente cronológico. No obstante, son varias las perspectivas de estudio ceramológico: sus formas de producción, las formas de distribución y comercialización y las pautas de consumo, etc. Todas ellas arrojan luz sobre aspectos que permiten estudiar las sociedades del pasado. En el caso que nos ocupa queremos discutir el valor de la cerámica en la comprensión del proceso de islamización social, es decir de integración en un nuevo sistema social y cultural. El siglo VII marca en el Mediterráneo occidental el final de un sistema económico de ámbito “mundial”, capaz de producir y distribuir cerámicas altamente estandarizadas y especializadas por todo el ámbito mediterráneo. El siglo X permite reconocer la reconstrucción de los mercados y la uniformización productiva y formal, que refleja la nueva sociedad representada en el Califato. Entre ambos extremos se abre un periodo interesante y complejo, plagado de luces y sombras, que permite reconocer tanto los procesos de reestructuración económica como la generalización de nuevos patrones culturales. En este trabajo se intentarán plantear los temas más importantes y novedosos sobre la cerámica de los siglos VII a X, a partir de varios trabajos recientes, leyendo a través de la cerámica el proceso de islamización.

Enlaces. Relatos sobre la conexión de tiempos y lugares

A través de algunos relatos en torno al espacio se ensaya un discurso sobre la conexión entre arte y vida, que postula la relación entre escenas, la continuidad entre arte y lugar, y el entrelazamiento creativo y narrativo entre disciplinas artísticas. El artículo pretende registrar la conexión, en ambos sentidos del vector, entre lugares y proyectos, un vínculo inasible pero real. Todo escritor persigue las marcas de la actividad humana sobre los objetos, la probatura de una teoría de los objetos inanimados que registramos desde nuestras herramientas de analogía y contraste antropométrico. Ése es también el empeño del arte y ésa era la definición del propio origen de la pintura de Plinio, el intento de retener la compañía de la persona amada dibujando la sombra de su perfil sobre una superficie, convertida en un museo espontáneo al fresco. Las obras de arte, como algunos proyectos, deberían ser hilos, en el tiempo y el espacio, enlaces del arte y la vida: entre nuestra mesa y el territorio, entre la mente y la materia, entre el hombre y el mundo.

El juego estratégico de Rusia en el Cáucaso Sur: Sochi 2014

La propuesta de la ciudad de Sochi como sede de los Juegos Olímpicos de Invierno y de la 16° fecha del Gran Premio de Fórmula 1 de 2014, y como una de las sedes de la futura Copa Mundial de Futbol 2018, son una ratificación de la importancia estratégica que representa el Cáucaso para Rusia. Asimismo, el anclaje en el Cáucaso y en las costas del Mar Negro, con toda la inversión en infraestructura y en seguridad que representa la organización de eventos deportivos mundiales, implica la puesta en juego de una estrategia geopolítica que expresa la importancia de Rusia como potencia regional. En el calidoscopio de poder e intereses que se despliegan en la región caucásica, la sombra de Rusia se proyecta con fuerza. Abordar el rol que ejerce este país en el Cáucaso Sur, permitirá comprender las perspectivas actuales de la política exterior de Rusia en esta región, así como conocer de qué modo se despliega en el territorio el juego estratégico del poder a través de eventos deportivos que se observan desde todos los lugares del mundo.

Luz e sombra em mensagem de Fernando Pessoa

A Mensagem de Fernando Pessoa é uma obra marcada por uma forte riqueza simbólica e com inesgotáveis potencialidades interpretativas. Neste caso, analisou-se o contraste luz/sombra, considerando- se que o Quinto Império é anunciado como teatro do dia claro e o sebastianismo que percorre a obra é mistério e nevoeiro. Observado o valor simbólico que pode ser atribuído a estes termos e analisadas as ocorrências de vocábulos que remetem para eles, concluiu-se que existe um elevado número de ocorrências de vocábulos associados à luz e que esta se relaciona com o heroísmo, o conhecimento e o Quinto Império. A sombra que atravessa a obra remete para o desconhecido, o perigo e, também, para o que, estando oculto, pode ser desvendado. Associa-se, deste modo, ao mito sebástico.

Pequena história do azul. O azul como imagem e limite do visível: Manlio Brusatin e a perspectiva pictórica

Among the conscience of the intrinsic value of the pictorial, it resides a continuum understanding of which is fundamental in the relationships and contradictions of succedaneum poetic acts, and they will be better understood as the better we think as M. Brusatin, in order to «dedicate ourselves to the painting return». Reminding all that which was symptomatic and repeatedly hidden and deprecated by the draw – «the colour as decorative complement of the narrative allegory of art history», in our interpretation about Storia dei Colori, we follow the painting in its nature-temporal-space, seeing the “colour-image”, the “colour- shadow”, the “flux to light in white-opacity”. We count the intrinsic vitality of bluish life in people’s cultures; listening to it in its deepness, also in the singular profession’s act, as «once upon a time there was a time again, naturally, the once upon the time of being the Painter» as, for instance, Rafael, Kandinsky, Yves Klein, Mark Rothko and Gerhard Richter.

Bank versus non-bank credit in the United States, Europe and China. Bruegel Policy Contribution, 2012/07, 5 June 2013

In the wake of recent crisis developments in the US and Europe, non-bank credit channels have often been portrayed as 'shadow banking' and have been considered primarily through the lens of the risks they may pose to financial stability. However, the debate about financial system structures remains immature, in large part due to lack of reliable and comparable data. The available evidence actually points towards a correlation between the development of non-bank credit and higher resilience against systemic risk, at least in developed economies. Policy should aim at better statistical information, and at strengthening the infrastructure for the gradual development of sustainable nonbank credit provision.

Europe between financial repression and regulatory capture. Bruegel Working Paper 2014/08, July 2014

From the Introduction. In the long shadow of the euro-area crisis, the relationship between governments and their banks has been brought to the the centre of the policy debate in Europe by the implementation of regulatory reforms, the risks associated with financial fragmentation, and the fight to sustain the flow of credit to governments and corporates. The attempt to interpret the patterns of pressure and influence running between governments and their financial system has led commentators to rediscover and give new life to concepts originating from academic debates of the 1970s such as “regulatory capture” and “financial repression”. Government agencies have been frequently described as being at the mercy of the financial sector, often allowing financial interests to hijack political, regulatory and supervisory processes in order to favouring their own private interests over the public good1. An opposite view has instead pointed the finger at governments, which have often been portrayed as subverting markets and abusing the financial system to their benefit, either in order to secure better financing conditions to overcome their own financial difficulties, or with the objective of directing credit to certain sectors of the economy, “repressing” the free functioning of financial markets and potentially the private interests of some of its participants2

Historic turning point or just another chapter? The results of a foreign-policy summit. EPC Post-Summit Analysis, 24 March 2014

The March 2014 European Council could enter the history books as a turning point, not only in the EU’s relations with Russia but also in its role as a foreign policy actor. Events in Ukraine inevitably dominated the Summit, with EU leaders adopting a balanced approach aimed at achieving three key objectives – de-escalation, containment/deterrence and cooperation – based on political and economic support for Ukraine, increased but limited pressure on Russia, and moves to strengthen ties with other EU neighbours. The Summit also discussed a range of economic and environmental policy issues, with the situation in Ukraine casting a long shadow over the discussion on energy policy, but failed to reach agreement on the EU’s climate goals to 2030, or to put more flesh on the bones of calls for a European “industrial renaissance”. However, two other developments were particularly significant: the creation of the second pillar of the future banking union, establishing a single regime for winding down failing banks; and changes to the savings tax directive, bringing years of negotiation to an end.

The NSA: the impact of the wiretapping scandal on German-American relations. OSW Commentary No. 124, 14.01.2014

Edward Snowden revealed that America’s National Security Agency (NSA) had tapped Chancellor Angela Merkel’s mobile phone and had collected date en masse. This has caused the largest crisis of confidence in relations between Germany and the US since the Iraq war. Due to the technological advantage which American intelligence services have, Germany wishes to continue close co-operation with the US but is making efforts to change the legal basis of this co-operation dating back to Cold War times. Berlin would like to secure part of provisions similar to the Five Eyes alliance – agreements signed between the US, the UK, Canada, New Zealand and Australia in the second half of the 1940s, aimed at intelligence sharing and a ban mutual bugging. This could spell the end of the last (not including the military presence) relic of Germany’s dependence on the US which emerged following World War II and took shape in the shadow of the Cold War. The process of Germany’s emancipation in trans-Atlantic relations, which began after Germany’s reunification, would be complete. The US is however opposed to such far-reaching changes as it is interested in continued co-operation with Germany without limiting it. Were it not to sign agreements satisfactory for Berlin, this would lead to a protracted crisis of confidence in German-American relations.

Slovakia: the Eurogroup’s enfant terrible. OSW Commentary No. 63, 2011-10-14

When Slovakia’s parliament rejected the European Financial Stability Facility (EFSF) reform on 11 October it undermined Slovakia’s reputation as a credible partner within the EU. Moreover, Prime Minister Iveta Radicova combined the vote on the strengthening of the EFSF – a key anti-crisis mechanism in the Eurozone – with a vote of confidence for her cabinet. This eventually led to the collapse of the government. Before Slovakia’s decision, the strengthening of the EFSF had been endorsed by the national parliaments of all the eurozone countries. Slovakia, which had opted to be the last one to carry out the ratification procedure, adopted the EFSF reform only in a re-vote on 13 October, due to the support of the opposition left-wing party. However, problems with ratification have cast a shadow over the achievements of Slovakia which as one of the freshest members of the eurozone had been actively seeking to influence the creation of EU mechanisms for dealing with the debt crisis. For the past eighteen months the Slovak government, formed by conservative and liberal parties, has consistently called for the controlled bankruptcy of Greece, a tightening of the rules of the Stability and Growth Pact, and for the private sector’s participation in financing the rescue packages for indebted states. It was in part down to Slovakia that these proposals, previously regarded as extreme, were introduced into the mainstream EU debate. The constructive position presented by Slovakia’s diplomacy in recent months has brought Bratislava tangible results, such as the reduction of its contribution to the permanent anti-crisis fund, the European Stabilisation Mechanism (ESM). Thus Slovakia, which adopted the single currency on 1 January 2009, has become an informal spokesman for the new, poorer members of the eurozone.
