Is economic growth sustainable in Romania?

The last events which took place after the 1st January 2007 and Romania’s admission in the European Union imply a sustainable and continuous economic growth, in order to reduce economic and social disparities between our country, EU average and other EU members, through a mobilization of the intern capital and labour force potential. Given this context, the paper aims at identifying and explaining, through a retrospective analysis, GDP fluctuations and tries to evaluate, using the aggregate supply-demand model, the contribution of each structural element in GDP formation and increase. Finally, the article proposes directions of action for continuing the sustainable development of Romania and reducing the gaps between this country and other EU members.nominal GDP, real GDP, aggregate demand, aggregate supply, growth factors

Implications of wage bargaining systems on regional differentiation in the European Union

The theoretical literature has argued that a centralized wage bargaining system may result in low regional wage differentiation and high regional unemployment differentials. The empirical literature has found that centralized wage bargaining leads to lower wage inequality for different skills, industries and population groups, but has not investigated its impact on regional wage differentiation. Empirical evidence in this paper for EU regions suggests that countries with more coordinated wage bargaining systems have lower regional wage differentials, after controlling for regional productivity and unemployment differentials.regional wage differentiation, wage bargaining system, regional unemployment differentials, regional productivity differentials

Searches for New Physics in Lepton Final States

Final states containing charged leptons could provide some of the most distinctive signatures for observing physics beyond the Standard Model. We present searches for new physics using 0.32-0.45 /fb of data accumulated at the Tevatron. No significant evidence of a signal is found, and in most cases the tightest constraints to date are set on the exotic processes investigated.Comment: 8 pages, Contribution to Proceedings of XLth Rencontres de Moriond 2006, Electroweak Interactions and Unified Theories, La Thuile, Italy, 11-18 March 200

Is China’s economic growth a danger for others economies?

Extrapolating past real GDP growth rates into the future, the size of the Chinese economy surpasses that of the U.S. in purchasing power terms between 2012 and 2015; by 2025, China is likely to be the world's largest economic power by almost any measure. The extrapolations are supported by two types of considerations. First, China’s growth patterns of the past 25 years since the beginning of economic reforms match well those identified by standard economic development and trade theories (structural change, catching up, and factor price equalization).max. economic growth, growth accounting, growth forecasts, development theories, human capital formation

Top Quark Properties

In this document we present several recent (July 2008) results from studies of the top quark properties at the CDF and D0 experiments at the Tevatron. Measurements of several top quark properties, as well as tests of new physics in the top quark production and decay sectors are presented. In the latter case, no significant evidence for physics beyond the Standard Model is uncovered, and the tightest constraints to date are placed on most of the new physics scenarios investigated.Comment: HCP 2008 proceedings on behalf of the CDF and D0 Collaborations.

The evolution of human resources from crude oil extraction and processing activities in Romania between 1990 and 2006

Providing qualified workers for the companies represents a step forward the normal and efficient operation of them. The modern industrial company presupposes that people should interact to each other, establishing multiple connections and passing through a continuous process of getting accustomed and integrated. The quality of the worker is given by the professional knowledge which allows him the fulfillment of the work tasks. The competence is the quality of the manpower in action. It reflects the capacity, the skills of the worker in his job, in fulfilling his tasks.human resources, oil extraction, professional knowledge

Romania and foreign direct investment

Thanks to a level of growth in foreign investment, the gap is narrowing between Romania and other East European countries like the Czech Republic, Poland and Hungary, countries normally considered the preferred choice of foreign investors. In the last years, Romania has become a more appealing target for an increasing number of foreign investors. After its accession in NATO in 2004 and in European Union in 2007, Romania positioned itself very firmly within the Euro - Atlantic zone, with all political, economical and military consequences deriving from it.foreign direct investment, economic growth, economic integration

A Provenance Tracking Model for Data Updates

For data-centric systems, provenance tracking is particularly important when the system is open and decentralised, such as the Web of Linked Data. In this paper, a concise but expressive calculus which models data updates is presented. The calculus is used to provide an operational semantics for a system where data and updates interact concurrently. The operational semantics of the calculus also tracks the provenance of data with respect to updates. This provides a new formal semantics extending provenance diagrams which takes into account the execution of processes in a concurrent setting. Moreover, a sound and complete model for the calculus based on ideals of series-parallel DAGs is provided. The notion of provenance introduced can be used as a subjective indicator of the quality of data in concurrent interacting systems.Comment: In Proceedings FOCLASA 2012, arXiv:1208.432
