The Labour Mobility in the European Union: Economic and Social Determinants
Liana Son,Ioan Talpos,Ciprian Sipos
Theoretical and Applied Economics , 2008,
Abstract: East and Central European countries are, most of them, migration countries for 18 years now and controversies on this subject are constantly emerging in the context of European Union enlargements. This paper aims to analyze some of the determinants of intra-European mobility and which are the interest destination countries for the migrant workers. The analysis is based upon a factorial model witch includes variables concerning the differential of labour cost and life and work conditions between European receiving and origin countries, in the decision of moving abroad.
A macroeconometric panel data analysis of the shaping factors of labour emigration within the European Union

Theoretical and Applied Economics , 2012,
Abstract: The research aims to identify and analyse the determinants and shaping factors of labour emigration within the European Union. The analysis is based on developing double-log macroeconometric models that combine cross-section and time series in a panel structure, by using a set of indicators specific for the emigration process, as well as for the economic activity, labour market and education, as main explanatory variables. The results show that high unemployment reduces the emigrant stock, mainly due to the loss of associated income and to the reduction of the migrants’ capacity to move and establish into another country. At the same time, we identified a positive selection of emigrants at destination according to their educational level, while an increase in education in the source country downsizes the stock of emigrants mainly due to an improvement in employment perspectives.

Abstract: The increasing amplitude of migrants and remittences in the last years, especially toward the developing countries has positive effects on development in the countries of origin. Empiric research outline the potentially significant effect of remittances on the economy of a country in various ways, as a source of external financing, contributing to the growth and economic development, to the increase of the national income and stimulation of consumption, and at the same time, important in financing households, contributing to poverty decrease. These challenges are a priority for Romania, an emigration country that receives every year un important volume of remittances, but, at present with a preponderant role in the consumption.

Abstract: The research aims to identify and analyse the impact of labour emigration on labour markets within the European Union. The analysis is based on developing double-log macroeconometric models that combine cross-section and time series in a panel structure, by using a set of indicators specific for the emigration process and labour market, as main explanatory variables. The results show that an intense emigration process has extremely negative effects on the size and structure of the labour force, generating its significant reduction, especially regarding the highly skilled labour. At the same time, we identified a relaxation of the labour market pressures generated by high unemployment, through a downsize of this rate and a slight increase in employment, mainly due to a general improvement of the local employment opportunities.
Influence of Microstructural Changes on Some Macro Physical Properties of Cement Mortar during Accelerated Carbonation  [PDF]
Son Tung Pham
Open Journal of Civil Engineering (OJCE) , 2014, DOI: 10.4236/ojce.2014.42008

The objective of this work was to examine the changes in the microstructure and macro physical properties caused by the carbonation of normalised CEM II mortar. Samples were prepared and subjected to accelerated carbonation at 20°C, 65% relative humidity and 20% CO2 concentration. On the microstructure scale, the evolutions of the cumulative pore volume, pore size distribution, and specific surface area during carbonation were calculated from the adsorption desorption isotherms of nitrogen. We also examined the evolution of macro physical properties such as the solid phase volume using helium pycnometry, porosity accessible to water, gas permeability, and thermal conductivity. The conflict between nitrogen porosity and water porosity results indicated that the porous domains explored using these two techniques are different and help to complementarily evaluate the effects of carbonation. This is a multi-scale study where results on microstructural changes can help to explain the evolution of macro physical properties.

Effects of Carbonation on the Microporosity and Macro Properties of Portland Cement Mortar CEM I  [PDF]
Son Tung Pham
Journal of Materials Science and Chemical Engineering (MSCE) , 2014, DOI: 10.4236/msce.2014.27005

The aim of this work was to examine the microstructural changes of CEM I standardised cement mortar caused by accelerated carbonation (20% CO2 concentration) using porosity accessible to water and nitrogen adsorption. The conflicted results obtained by these two techniques showed the differences in porous domains explored, while the pore size distributions calculated from nitrogen adsorption provided evolution of the micro and meso pores during carbonation. The porosity accessible to water showed changes in all three porous domains: macro, meso and micro pores. This is because of difference in the molecular sizes between water and nitrogen molecules. Although these two techniques are different, they help to complementarily evaluate the effects of carbonation. The results also indicated the influence of type of cement on microstructural evolutions and the correlation between variations of mesopores volume and specific surface area. Changes in microstructure induce changes in macroscopic properties that we also examined such as the solid phase volume using helium pycnometry, the gas permeability, the thermal conductivity, the thermal diffusivity, and the longitudinal and transverse ultrasonic velocities.

Supply Chain Risk Management: A Review of Thirteen Years of Research  [PDF]
Célestin Elock Son
American Journal of Industrial and Business Management (AJIBM) , 2018, DOI: 10.4236/ajibm.2018.812154
Abstract: This paper performs a systematic literature review on supply chain risk management (SCRM). This review analyzes 133 articles published between 2005 and the first quarter of 2018. Its main purpose is to identify the developed strategies used to mitigate risks and improve supply chain performance. It appears that there is heterogeneity in the developed strategies and that quantitative methods simulation/modeling are the most used by researchers to mitigate supply chain risks (SCR). Although emphasis is made on the links between SCRM and performance or resilience, risk prevention strategies remain the least represented in the papers analyzed. We also find that there is no superior approach in the set of various risks management strategies and thus it is difficult to linearly establish, the successive evolutions of the models that would replace others.
Hybridisation of Evolutionary Algorithms for Solving Multi-Objective Simulation Optimisation Problems
Liana Napalkova
Scientific Journal of Riga Technical University. Computer Sciences , 2009, DOI: 10.2478/v10143-010-0001-2
Abstract: The paper presents a taxonomic analysis of existing hybrid multi-objective evolutionary algorithms aimed at solving multi-objective simulation optimisation problems. For that, the properties of evolutionary algorithms and the requirements made to solving the problem considered are determined. Finally, a combination of the properties, which allows one to increase the approximation accuracy of the Pareto-optimal front at relatively low computational costs, is revealed.

Reformulation of Language in the Commentaries Accompanying Russian Legislation in the Field of Intellectual Property
Liana Goletiani
Slavica TerGestina , 2011,
Abstract: The paper studies the linguistic value of reformulation of language in the commentaries accompanying legal texts, to make them comprehensible to non-lawyers. The author has analysed the text of Chapter Four of the Civil Code of the Russian Federation, which covers Intellectual Property Rights, and the text of Methodical Guidelines, regarding their implementation, published by the Chamber of Commerce and Industry of the Russian Federation which is aimed at improving the level of legal competence of businesspeople. The author shows that in this type of legal metatext, when interpreting the intention of the legislator the most common reformulation methods are exemplification, renaming, syntactic simplification and rearrangement, enumeration and precision.
