Constraints on light neutrino parameters derived from the study of neutrinoless double beta decay

The study of the neutrinoless double beta ($0 \beta\beta$) decay mode can provide us with important information on the neutrino properties, particularly on the electron neutrino absolute mass. In this work we revise the present constraints on the neutrino mass parameters derived from the $0 \beta\beta$ decay analysis of the experimentally interesting nuclei. We use the latest results for the phase space factors (PSFs) and nuclear matrix elements (NMEs), as well as for the experimental lifetimes limits. For the PSFs we use values computed with an improved method reported very recently. For the NMEs we use values chosen from literature on a case-by-case basis, taking advantage of the consensus reached by the community on several nuclear ingredients used in their calculation. Thus, we try to restrict the range of spread of the NME values calculated with different methods and, hence, to reduce the uncertainty in deriving limits for the Majorana neutrino mass parameter. Our results may be useful to have an up-date image on the present neutrino mass sensitivities associated with $0 \beta\beta$ measurements for different isotopes and to better estimate the range of values of the neutrino masses that can be explored in the future double beta decay (DBD) experiments.Comment: 11 page

Flexicurity in EU Countries

Flexicurity is a new way of looking at flexibility and security on the labor market. It sets out from the awareness that globalization and technological progress are rapidly changing the needs of workers and enterprises. Companies are under increasing pressure to adapt and develop their products and services more quickly. If they want to stay in the market, they have to continuously adapt their production methods and their workforce. This is placing greater demands on business to help their workers acquire new skills. It is also placing greater demands on workers with regards to their ability and readiness for change. At the same time, workers are aware that company restructurings no longer occur incidentally, but are becoming a fact of everyday life. Protection of the specific job they have may no longer be sufficient, and might indeed be counterproductive. In order to plan their lives and careers, workers need new kinds of security that help them remain in employment, and make it through all these changes. New securities must go beyond the specific job and ensure safe transitions into new employment. Flexicurity is an attempt to unite these two fundamental needs. Flexicurity promotes a combination of flexible labor markets and a high level of employment and income security and it is thus seen to be the answer to the EU's dilemma of how to maintain and improve competitiveness whilst preserving the European social model. Flexicurity can be defined, more precisely, as a policy strategy to enhance, at the same time and in a deliberate way, the flexibility of labor markets, work organizations and labor relations on the one hand, and security –employment security and income security – on the other.flexicurity; flexibility; security; benefits; labour force

Risk Culture, A Necessity for the Risk Management Process Development in Public Institutions

The profound economic and financial crisis that has globally manifested recently has highlighted the managers and systems management’s inability to identify in the early stage, the existing dangers and to design strategies to reduce the negative effects. Organizations that have developed a culture of risk awareness and a high level of risk, have survived in a changing economic environment by reducing waste, cost reduction and strategic flexibility. In the post crisis period, many organizations are focusing all their energy to survive in an uncertain environment, trying to reduce losses, reduce costs and to achieve their objectives. When attention is directed to the risks, the concerns are often focused more for improving existing risk management system and less on developing a risk culture within the institution. Leadership can support the risk culture to influence a proper behavior, which helps the organization to meet its goals and embody its values.financial control, internal audit, risk management, risk culture.

The Employment and Unemployment in Romania - Decisive Factors

The employment, but also the efficient use of the available work resources is directly connected to the work market. It is an element that can not be separated from the other elements of the work market, especially from unemployment, because if one deals with them separately, one can not cover all the aspects, particularities and effects on the work factor. There are many causes for unemployment, causes that are to be found both at the macroeconomic level and at the microeconomic level. In most of the cases, in an analysis that aims at finding the causes that have generated the unemployment, many characteristics of unemployment are taken into account and they are analysed as “types” of unemployment.Employment; Unemployment; Wages; Intergenerational Income Distribution
