GLOBALIZATION & REGIONALIZATION IN INTERNATIONAL TRADE

The concept of globalization refers to the growing interdependence of countries, resulting from the increasing integration of trade, finance, investments, labor markets and ideas in one globalmarketplace. The most important elements of this process are the international trade and the cross-border investment flows. Economic globalization has increased the specialization of workers, while the companies compete in global markets. Even globalization has recently become a common topic in academic discourse, many economists focused, from the 1980s and 1990s, in addition to globalization, on regionalization - the growth of networks of interdependence within multinational regions of the world. The recent decades arecharacterized by the fact that the world trade grew faster than world output, which implies that an increasing share of world GDP crosses international borders. The trend is explained, mostly, by thesubstantially declining of the trade barriers during the same period, as a result of successive trade negotiation rounds under the auspices of the GATT/WTO, unilateral trade liberalization and regional tradeagreements. Even there are global connections between all the countries, the strongest political and economic integration is being created within a few specific regions of the world: Europe, North America and East Asia.globalization, regionalization, international trade, trade agreement, trade liberalization, economic integration, global market

An Optimized Structure-Function Design Principle Underlies Efficient Signaling Dynamics in Neurons.

Dynamic signaling on branching axons is critical for rapid and efficient communication between neurons in the brain. Efficient signaling in axon arbors depends on a trade-off between the time it takes action potentials to reach synaptic terminals (temporal cost) and the amount of cellular material associated with the wiring path length of the neuron's morphology (material cost). However, where the balance between structural and dynamical considerations for achieving signaling efficiency is, and the design principle that neurons optimize to preserve this balance, is still elusive. In this work, we introduce a novel analysis that compares morphology and signaling dynamics in axonal networks to address this open problem. We show that in Basket cell neurons the design principle being optimized is the ratio between the refractory period of the membrane, and action potential latencies between the initial segment and the synaptic terminals. Our results suggest that the convoluted paths taken by axons reflect a design compensation by the neuron to slow down signaling latencies in order to optimize this ratio. Deviations in this ratio may result in a breakdown of signaling efficiency in the cell. These results pave the way to new approaches for investigating more complex neurophysiological phenomena that involve considerations of neuronal structure-function relationships

REASONS AND EFFECTS OF THE ROMANIAN LABOUR FORCE MIGRATION IN EUROPEAN UNION COUNTRIES

In the European Union countries and neighboring regions, the expansion will produce a redistribution of the labour force between industries and countries. After the Romania’s adhesion to theEuropean Union, the need for an increased productivity, the lack of capital, the competition on the EU market and the low wages have concurred to the intensification of the migration process of the labour force, especially to the West European countries. As example, from over two millions of Romanians working abroad (almost 10 % from total population), 40% have chosen to work in Italy, 18% in Spain, 5% in Germany. In this context, the questions that appear refer to the following issues: Does a real possibility exist for the emigrants to join the active population of the destination country and being employed according to their competences? How many Romanians citizens continue to stay in a foreign country if their job is not proper with their professional skills? Which countries in European Union apply discriminations on its labour market? Do European Countries usually admit Romanian employees temporarily and expect them to leave in short time if they can’t find a proper job? Which are the socio-economic effects of labour mobility on the Common Market of EU? Which are the forecasts concerning the labour mobility in the next years?In our paper, we try to answer these questions and we also intend to make a comparative analysis concerning - what we consider - some of the most important challenges occurred in Romania’s economy inthe context of the mentioned migration process: the adoption of an economic growth model based on the increase of the employed population, the diminution of the discrepancies between our country labour market and the EU target established through Lisbon Strategy, the creation of a new structure of occupation with support in productivity growth and labour price.Romanian emigrants, labour market, European Union, migration effects

Planning for Decentralized Control of Multiple Robots Under Uncertainty

We describe a probabilistic framework for synthesizing control policies for general multi-robot systems, given environment and sensor models and a cost function. Decentralized, partially observable Markov decision processes (Dec-POMDPs) are a general model of decision processes where a team of agents must cooperate to optimize some objective (specified by a shared reward or cost function) in the presence of uncertainty, but where communication limitations mean that the agents cannot share their state, so execution must proceed in a decentralized fashion. While Dec-POMDPs are typically intractable to solve for real-world problems, recent research on the use of macro-actions in Dec-POMDPs has significantly increased the size of problem that can be practically solved as a Dec-POMDP. We describe this general model, and show how, in contrast to most existing methods that are specialized to a particular problem class, it can synthesize control policies that use whatever opportunities for coordination are present in the problem, while balancing off uncertainty in outcomes, sensor information, and information about other agents. We use three variations on a warehouse task to show that a single planner of this type can generate cooperative behavior using task allocation, direct communication, and signaling, as appropriate

Progress in integrated-circuit horn antennas for receiver applications. Part 1: Antenna design

The purpose of this work is to present a systematic method for the design of multimode quasi-integrated horn antennas. The design methodology is based on the Gaussian beam approach and the structures are optimized for achieving maximum fundamental Gaussian coupling efficiency. For this purpose, a hybrid technique is employed in which the integrated part of the antennas is treated using full-wave analysis, whereas the machined part is treated using an approximate method. This results in a simple and efficient design process. The developed design procedure has been applied for the design of a 20, a 23, and a 25 dB quasi-integrated horn antennas, all with a Gaussian coupling efficiency exceeding 97 percent. The designed antennas have been tested and characterized using both full-wave analysis and 90 GHz/370 GHz measurements
