Currently, at the European Union level, there has been an increase in unemployment, especially youth unemployment, as a result of certain imbalances in the labor market, exacerbated by the current financial and economic crisis. The sustainable economic development of each country is strongly influenced by the human resource in the context in which it is sought the creation of a strong, competitive and prosperous Europe. The human resource and especially young people are the most precious wealth of a nation. Therefore, solving the problem of youth unemployment is a matter of great concern and requires bringing to the forefront modern employment policies correlated with the economic reality, to which the EU attaches increasingly more importance, namely promoting green employment in a green economy. Our paper begins by analyzing the evolution, causes and differences recorded at the European Union level on the size and structure of youth unemployment and it ends with identifying some measures to reduce it, in the context of European sustainable development. The conclusions in our research highlight the importance of employment policies at both the micro and macro level and show the positive role of active policies, investment in education and green employment. © 2015 by the authors.

The paper builds a general dynamic intersectoral model with structural characteristics and tests the change in the behavior of inflation in the presence of a symmetry breaking. Two hypotheses are tested relating the symmetry groups of the model described by the geometric transformations that leave unchanged the offer variation graph with the symmetry group of the price variation graph. The results suggest that a change in the pattern of inflation is associated with the change in the symmetry groups. © 2013 IEEE.

Over the past decade, there has been increasing evidence describing the importance of clothing involvement in the apparel purchase decision, the role of apparel hang tags in shaping consumers' attitudes and behaviors relative to SR patronage decisions, the environmental consequences of production and disposal of fashion textiles, and consumers' willingness to pay for domestically made or grown products. The mainstay of the paper is formed by an analysis of the importance of green products and their promotion to consumers, the use of point-of-purchase promotional communications to inform consumers about apparel companies' engagement in SR business practices, the impact of consumers' perception of green campaign on the acceptance of green consciousness, and biog advertisements' effects on consumer behavior. Our paper contributes to the literature by providing evidence on the impact of enhanced design and quick response on consumer purchasing behavior, the importance of social norms in a consumption context, the effect of environmental claims in clothing promotion, and the importance of understanding consumer involvement in retailing.

The present paper proposes a development framework of the nanorobots as functional heterogeneous nanosystems governed by the synergistic integration both at functional and structural levels. The main concept is that of the USIPS (Unified Synergistic Information and Power Signal) that represents both the information and power flows in nanorobots, and is the support for information processing, control, decision, movements and forces generation and application in performing nanorobot's actions in and/or upon the working environment. Using the USIPS concept, 25 fundamental operations are determined, that integrate the representation of perception, processing, decision and actions. These operations together with the USIPS concept are used to develop at the operational level a nanorobot, but also every nanosystem. Thus, the proposed framework is a design approach that may be considered also as a support for CAD environments for nanorobots and nanosystems in general. © 2012 SPIE.

The optical properties of p-i-n solar cells comprised of InAs quantum dots embedded within GaNAs and GaInNAs quantum wells are reported. Strain compensating and mediating GaNAs and GaInNAs layers shift the photoluminescence emission as well as absorption edge of the quantum dots to longer wavelengths. GaNAs and GaInNAs quantum wells contribute also to extending the absorption edge. In addition, the use of GaNAs and GaInNAs layers enhances the thermal escape of electrons from QDs by introducing steps for electrons to the GaAs conduction band. © 2015 Acta Materialia Inc.
