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.

This research was started in order to make more attractive and more likeable the lessons of safety performed by our institute for various industrial operators. In this respect we have developed some reusable learning frames that are used together with a dynamic safety avatar (John) in order to make the lessons more interesting and optimal from the safety point of view. Such a lesson could be disseminated on line or off-line and its results are analysed in order to have a continuous improvement. The system was tested on an enterprise with 300 employees during 2 months of testing (June-July 2014) and the results are encouraging. © 2016 IChemE.

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.

Electron irradiation is found to cause a large blue shift of photoluminescence from a 1.3-μm laser-like strain-compensated GaInNAs/GaNAs/GaAs quantum well structure when annealed after irradiation. The line shift is assigned to the presence of complex defect centers in the quantum wells. The defects are very unstable. The peak position and line shape of the spectra are restored to their original values by an ageing effect, which occurs even at room temperature. The mechanism causing the blue shift/red shift of photoluminescence is qualitatively described. © 2014 Elsevier B.V.

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.

The effects of growth temperature (410 and 470°C) and subsequent rapid thermal annealing (RTA) on luminescence performance of lattice-matched 1-eV GaInNAs-on-GaAs epilayers, grown by molecular beam epitaxy under constant fluxes, has been studied experimentally by 9-K photoluminescence (PL) and 300-K photoreflectance (PR) spectroscopy. The near band edge PL has been found to noticeably decrease and red-shift as the growth temperature (Tgr) is reduced from 470 to 410°C. This red-shift is the consequence of a reduction in the alloy band gap with decreasing Tgr, as confirmed by PR. An N-related broad PL band, whose intensity remarkably enhances with increasing Tgr, has been detected at longer wavelengths in the 9-K PL's. Post-growth RTA (1 min at 800°C) significantly enhanced the near band edge PL but it did so at the expense of a PL blue-shift: the more the PL enhancement and blue-shift the lower the Tgr. This annealing-induced blue-shift is due to In-N bonds formation, whose magnitude enhanced as the Tgr is decreased. The broad PL band also enhanced upon the RTA, but the ratio between its intensity and the intensity of the near band edge PL reduced, especially for the sample grown at 410°C. 7-MeV electron irradiation to the dose of around 1015 cm-2 applied prior to annealing considerably reduced the broad PL band upon annealing. © 2013 Elsevier B.V.

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.

This article presents a theoretical model for a dynamic system based on sustainable development. Due to the relatively absence of theoretical studies and practical issues in the area of sustainable development, Romania aspires to the principles of sustainable development. Based on the concept as a process in which economic, social, political and natural environment are combined in order to sustain planet management, our goal is to promote an economic tool for Romanian decision-makers in order to evaluate scenarios and planning options.

The green area of economy is the key of healthy living. It is necessary to convene economic and ecologic framework to establish a market attentive to drastic reduction of emissions damaging our climate and landscapes in rural areas, to the protection of biological diversity of the planet, to stop producing nuclear waste, etc. This paper tries to demonstrate human concern for a waste recycling economy that will provide new jobs, will create economic and social stability and will ensure a healthier and cleaner environment. Green Economy and its support system (planetary ecosystem) won't be in conflict anymore. Green Economy will be able to support economic progress for future.
