Innovations and Experiments in Uses of Health Manpower—The Effect of Licensure Laws

Time-resolved optical spin orientation is employed to study spin dynamics of I * and I-1* excitons bound to isoelectronic centers in bulk ZnO. It is found that spin orientation at the exciton ground state can be generated using resonant excitation via a higher lying exciton state located at about 4 meV from the ground state. Based on the performed rate equation analysis of the measured spin dynamics, characteristic times of subsequent hole, electron, and direct exciton spin flips in the exciton ground state are determined as being tau(s)(h) = 0.4 ns, tau(s)(e) greater than= 15 ns, and tau(s)(eh) greater than= 15 ns, respectively. This relatively slow spin relaxation of the isoelectronic bound excitons is attributed to combined effects of (i) weak e-h exchange interaction, (ii) restriction of the exciton movement due to its binding at the isoelectronic center, and (iii) suppressed spin-orbit coupling for the tightly bound hole

Decent work in Bulgaria

This study develops the issue of Decent work in Bulgaria focusing on employment conditions e.g. employment contracts, working time, wages, health and safety at work place, access to training, conciliation of work and family, as well as some specific issues like child labour, in particular. When studying the effects of structural and technological transformations in Bulgaria on decent work environment the authors have paid special attention on the analysis of the interrelations and linkages between the different elements of decent work. Important aspect of the analysis is that of the relevance between some economic and social policies and the achieved progress. The development of socio-economic and political environment in Bulgaria in the period 1995-2006 outlines stable upward trend of improvement in work conditions. In some segments the improvement had been more visible, while in others – not. Irrespective of this, the ongoing debates on the issues and the more attention, paid by policy-makers on it, should be considered as a first step of the progress. As a second step we have to consider the more consistent and relevant character of the applied policies that were introduced since 2000. The study includes two parts. In the first it analyses the trends in the development of the elements of decent work in Bulgaria, numbered above. This analysis is based on the available statistics and in some cases it covers the period 1995-2006, but in others – it does not because of lack of regular statistical observations. The second part of the study deals with some interactions between the elements of decent work. They are analysed taking into consideration their multi-dimensional character and available statistical information. Some of the linkages and trade-offs are metrically assessed (where it is possible), while the others are based on qualitative assumptions and evaluations. As a result the study identifies the main vulnerable groups.employment condition, employment contract, working time, wages, health and safety at work place, access to training, conciliation of work and family
