The New Economy- Knowledge Based Economy
The aim of this paper is to emphasize the importance of knowledge based economy, in this time characterized by fast changes and sometimes radical changes, it is impossible to resist without adapting, both people and the organizations too. The matter of the paper develops knowledge based economy concept: elements, definitions of the knowledge based economy, stages and the main knowledge codification. In the end of the paper, the author presents the importance of economy knowledge, in Romanian organizations.knowledge based economy, knowledge society, knowledge based organization, longlife learning, learning organization
Spatial matching of M configurations of points with a bioinformatics application
In this paper, we present a model to deal with the problem of matching M objects or configurations of points. This is a generalization of the model proposed by Green and Mardia (2006). We consider, as a direct and simple application, the case of three configurations with labelled and with unlabelled points. In both cases, we consider data from a microarray experiment of gorilla, bonobo and human cultured fibroblasts published by Karaman et al. (2003). We find out the matchings and the best affine transformation between the projections of genes in a two dimensional space, obtained by a Multidimensional Scaling technique.

Ultrasonic, molecular and mechanical testing diagnostics in natural fibre reinforced, polymer-stabilised earth blocks
The aim of this research study was to evaluate the influence of utilising natural polymers as a form of soil stabilization, in order to assess their potential for use in building applications. Mixtures were stabilized with a natural polymer (alginate) and reinforced with wool fibres in order to improve the overall compressive and flexural strength of a series of composite materials. Ultrasonic pulse velocity (UPV) and mechanical strength testing techniques were then used to measure the porous properties of the manufactured natural polymer-soil composites, which were formed into earth blocks. Mechanical tests were carried out for three different clays which showed that the polymer increased the mechanical resistance of the samples to varying degrees, depending on the plasticity index of each soil. Variation in soil grain size distributions and Atterberg limits were assessed and chemical compositions were studied and compared. X-ray diffraction (XRD), X-ray fluorescence spectroscopy (XRF), and energy dispersive X-ray fluorescence (EDXRF) techniques were all used in conjunction with qualitative identification of the aggregates. Ultrasonic wave propagation was found to be a useful technique for assisting in the determination of soil shrinkage characteristics and fibre-soil adherence capacity and UPV results correlated well with the measured mechanical properties
A combination of SEM and EDX studies on a clay-based natural composite with animal fibre and its mechanical implications
A variety of natural fibres are nowadays being utilized as soil reinforcement. Test results demonstrate the positive effects of adding natural fibres to soils, in that they decrease shrinkage, reduce curing time and enhance compressive, flexural and shear strength if an optimum reinforcement ratio can be utilised. This paper describes a study which uses a Scanning Electron Microscope (SEM) and an Energy Diffraction Analysis of X-rays (EDX) technique on clay-based composites stabilized with natural polymer and fibres. Different dosages of fibres and several types of soils have been used in this study with the aim of determining advantageous properties for building material applications. SEM and EDX test results reveal the degree of bonding between the particles of soil and the natural fibers. This has enabled a better understanding of the micro-morphology of the natural fibers and their effect on the overall composite material structure. Microscopic analysis was combined with mechanical tests to establish the different strength characteristics of every soil

THE POLICY OF THE EXCHANGE RATE PROMOTED BY NATIONAL BANK OF ROMANIA AND ITS IMPLICATIONS UPON THE FINANCIAL STABILITY
The more profound world economic crisis has strongly marked the evolution of the Romanian financial system. The size of current account deficit, the relatively high external financing needs and the dependence of the banks on it, the high ratio between loans in foreign currency and deposits in foreign currency made of the Romanian economy, a risky destination for investors. In these conditions, since the end of 2008 and throughout 2009, the government's economic program was focused on reducing the external deficit in both public and private sector, on minimizing the effects of recession, on avoiding a crisis of the exchange rate and on cooling the inflationary pressures.monetary policy, exchange rate, external financing, budget deficit
ON-LINE COMMUNICATION BY SOCIALIZATION SITES
Socialization online sites have become important landmarks for people all around the world and of all ages, especially for youth. Users of such services can socialize with people they know or with unknown, people located in the vicinity or at different distances, even on different continents. In other words, social online sites help people to interact with others of their kind, to know people who have the same passions as they have. The access to such sites is free and the members can build profiles (which include data on name, age, hobbies or favorite books and movies) and can share photos, music or videos with the others. A friend is, in the language of the socialization sites, any user who has a link to his/her profile page. Users can send messages or can leave comments on other profiles. In some cases, people who meet on such sites decide to meet also in the real life.internet, on-line, socialization sites, privacy
Strategies being pursued by Romanian HEIs to support knowledge transfer
Even though the higher education model of universities in Romania corresponds to a Humboldtian model based on harmonizing teaching and research activities, in recent years, under pressure from the knowledge-based economy, research activity has tended towards an increased role. Therefore, the role of universities across Romania is beginning to shift towards an entrepreneurial one. This paper seeks to identify the strategies that universities are currently developing to sustain the process of knowledge transfer. To achieve the above aim, semi-structured interviews were conducted with 14 university managers from research-intensive universities. The data was analysed using a coding system that was developed based on the theoretical framework. The results indicate a tendency among Romanian universities towards a linear model of tackling knowledge transfer, meaning that the primary focus is on establishing networks and partnerships between researchers and other categories of end users and on developing cross-domain research teams among researchers from the same university.A pesar de que el modelo de educación superior de las universidades en Rumanía corresponde a un modelo humboldtiano, basado en la armonización de las actividades de enseñanza e investigación, en los últimos años, bajo la presión de la economía basada en el conocimiento, la actividad de investigación ha aumentado su protagonismo. El modelo ha cambiado hacia un enfoque más económico. Este artículo busca identificar las estrategias que las universidades están desarrollando actualmente para sostener el proceso de transferencia de conocimiento hacia la práctica y la política educativa. Para seguir el objetivo mencionado anteriormente, se realizaron entrevistas semiestructuradas con 14 directores universitarios de las universidades con investigación intensiva. Los datos se analizaron utilizando un sistema de codificación que se desarrolló basándose en el marco teórico. Los resultados indican la tendencia de implementar un modelo lineal para abordar la transferencia de conocimiento, lo que significa apuntar hacia la necesidad de crear redes de trabajo entre investigadores y profesionales desarrollando equipos interdisciplinares y de multinivel que contribuyan a mejorar las relaciones entre los diferentes ámbitos de la producción y utilización de la investigación.Tot i que el model d'educació superior de les universitats a Romania correspon a un model humboldtià, basat en l'harmonització de les activitats de formació i recerca, en els últims anys, sota la pressió de l'economia basada en el coneixement, l'activitat de recerca ha augmentat el seu protagonisme.
