INDIVIDUAL CAREER IN THE CURRENT ECONOMIC CRISIS

Human resources represent the creative, active and coordinating element of the organisational activity, having a strong influence on the efficiency of the use of material, financial and information resources. The description of people as ”resources” highlights their importance and shows that their management requires high levels of genuine care and attention to people and professionalism. 2010 and 2011 are very difficult years for those who want to find a job. Flexibility and a decent salary are the reference words. The economy in a turbulent situation does not guarantee the safety of the jobs. The university graduates must make efforts and prove to have communication skills in order to obtain or keep the desired position. Our paper focusses on the aspects of career development for the young university graduates, thus treating a subject of wide interest these days.job, career development, flexibility, university graduates labour force

Romania - part of the EU's Eastern Frontier: opportunities versus responsibilities

After 2007 Romania became one of the eastern frontier states of the European Union. This double status of national state and frontier state comes itself with both the responsibility of keeping a high level of security for the EU’s border, and at the same time it can be seen as an opportunity for the Romanian state of increasing its regional power inside and outside the organization. At the same time, the Eastern non-EU member states seemed to be caught in the middle between the Russian Federation and the EU, fact that affected their national security level and tended to create a fragmentation within the EU. After its integration in the European structures, Romania’s strategy was constructed around the aspect of supporting and promoting the Republic of Moldova’s EU integration. The present paper analyses this double status of Romania and its possible effects

Border / frontier cities: between communication and fragmentation

The globalisation phenomenon led to the relaxation of borders all over the world. But, at the same time it generated the appearance of invisible frontiers which may create deeper fragmentations inside the society. Apart from the national states, the cities are also markers of identity and places where the ethnic, religious, social, economic differences are more sensible. The present article tackles the issue of frontier / border cities in order to highlight the differences between them and to analyse how the border / frontier affect their development.

Free energy landscape and characteristic forces for the initiation of DNA unzipping

DNA unzipping, the separation of its double helix into single strands, is crucial in modulating a host of genetic processes. Although the large-scale separation of double-stranded DNA has been studied with a variety of theoretical and experimental techniques, the minute details of the very first steps of unzipping are still unclear. Here, we use atomistic molecular dynamics (MD) simulations, coarse-grained simulations and a statistical-mechanical model to study the initiation of DNA unzipping by an external force. The calculation of the potential of mean force profiles for the initial separation of the first few terminal base pairs in a DNA oligomer reveal that forces ranging between 130 and 230 pN are needed to disrupt the first base pair, values of an order of magnitude larger than those needed to disrupt base pairs in partially unzipped DNA. The force peak has an "echo," of approximately 50 pN, at the distance that unzips the second base pair. We show that the high peak needed to initiate unzipping derives from a free energy basin that is distinct from the basins of subsequent base pairs because of entropic contributions and we highlight the microscopic origin of the peak. Our results suggest a new window of exploration for single molecule experiments.Comment: 25 pages, 6 figures , Accepted for publication in Biophysical Journa

A review of mental models research in child-computer interaction

AbstractResearch in cognitive science, science education, and developmental psychology has long investigating how children, based on their everyday experience, construct mental models of the world they live in. This paper provides a review of the research investigating the nature of mental models in the context of child-computer interaction, review elicitation techniques used within the field, and discusses its potential to further inform the design process. Exploring children's mental models of new technologies may bring about some further understanding in their cognitive and conceptual development, thus promting parents and teachers to guide them in exploring the new technological environment

The role of the cognitive behavioral approach in the reduction of the risk of recidivism for the persons under surveillance of the probation service

AbstractThe present paper has the following objectives: the description of the main characteristics of the approach to the offenders’ rehabilitation, based on structured group programs and the description of the effects that structured group program (“Heads or tails”) have in relation to the subjects’ resources and their willingness to reconsider their attitudes towards themselves, reality (justice, rules, customs etc.), and their positive behavioral changes. The results showed that subjects who followed this program have revised their perception on the reality, being able to make a cost-benefit analysis with a focus on a socially desirable decision

The interprofessional organizations - from the need of establishment to the need of development and affirmation

Through the present study it aims to represent the actual image of the interprofessional organizations on product chain in Romania, reflecting briefly the establishment and development issues. In the context of the reorganization of entire agrifood production system, in dealing with future crises, whatever is their nature, it’s needed to seriously manage the organizational issues and to present them as a useful tool for increasing the access to new markets for producers and to offer local products quality to consumers in Romania both. Using the documentation method it was obtained an overview of the relationship between the need of affirmation and the real need to convert the interprofessional organizations in Romania in functional structures. The Ministry of Agriculture and Rural Development recognized till now only five IPO but the analysis and the directly involved interprofessional organizations opinions exchanges, it was emerged some primordial issues in order to improve the legislation of interprofessional organizations on product chain. The interprofessional organizations on product chain are meant, almost in ingrate way, to be interposed between the pressing help need in the development of intra-community trade relationships and the stiffness required by the legislation

Growth of nannochloris algae in the presence of microwaves (continuous reactor)

[EN] Algae are very effective in capturing the sun's energy, carbon dioxide from the atmosphere, and nutrients to turn them into useful substances (carbohydrates, oils, proteins, etc.). Besides the main metabolites, there are also secondary metabolites, such as carotenoids (astaxanthin, β-carotene, lutein, lycopene, and canthaxanthin [1]). Both major and compounds existing in small amounts in algae are useful. Oils and carbohydrates could provide biofuels, proteins can get products with nutritional value and from carotenoids can be prepared food supplements. Obtaining biofuel from algae has not yet proved to be economically viable [2, 3]. A much higher interest might be getting food supplements from algae. To increase their value as ingredients for food supplements, algal oils should have a higher degree of unsaturation (rich in omega 3) and an increased carotenoid content to be an important additional benefit in over all processing of algae. There are studies that refer to the influence of environmental factors on algae composition [2], but the microwave influence on algae growth, especially algal metabolites composition change is very poor studied. In this paper, besides the experiments for the activation of algal growth in discontinuous reactors [4] additional work was conducted in a continuous photobioreactor. The goal was checking not only the growth of microalgae but also their content in polyunsaturated oil and in carotenoids. By microwave-controlled irradiation of the nutrient and algae flux, which is recirculated through the photobioreactor and through a glass reactor located in a TE-type monomod cavity, the lipid content of the algae increased, but only, the modification of the lipid fraction content was significantly increased in the concentration of polyunsaturated acids with 16 and 18 carbon atoms. As far as carotenoids are concerned, the algae nannochloris has a higher carotenoid content over many known vegetables holding carotene or lycopene (carrots or tomatoes). Besides oil increasing microwave treatment produced a significant increase in carotenoid content of algae. They can be extracted together with omega-3-rich algal oil and are the basis of very valuable dietary supplements.The authors acknowledge the financial support received from the Competitiveness Operational Programme 2014-2020, Action 1.1.4: Attracting high-level personnel from abroad in order to enhance the RD capacity, project: P_37_471, „Ultrasonic/Microwave Nonconventional Techniques as new tools for nonchemical and chemical processes”, financed by contract: 47/05.09.2016Calinescu, I.; Vintila, A.; Diacon, A.; Vinatoru, M.; Chipurici, P.; Galan, AM.; Velea, S.
