Range Expansion of Metcalfa pruinosa (Homoptera: Fulgoroidea) in Southeastern Europe
Cristina Preda,Marius Skolka
Ecologia Balkanica , 2011,
Abstract: The citrus flatid planthopper Metcalfa pruinosa, a Nearctic species of Fulgoroidea: Flatidae, was accidentally introduced in Europe, first in Italy in the late 1970’s. In a few decades, Metcalfa pruinosa has spread over most of Europe, finally reaching the Black Sea coast in 2009. Hundreds of individuals of different life stages were observed for the first time in the southeastern part of Romania throughout the summer of 2009 on several host plants: Hibiscus syriacus, Ligustrum vulgare, Robinia pseudoacacia, Evonymus japonicus, Spirea x vanhouttei, Aesculus hippocastanum, Philadelphus coronarius, Ficus carica, Vitis vinifera, Fraxinus pennsylvanica. The number of individuals observed and the area covered increased dramatically in 2010 as well as the number of host plants (110 species in 49 families), suggesting the planthopper is in the expansion phase of the invasion process.
LATERAL BRANCHIAL CYST – A FORGOTTEN DIFFERENTIAL DIAGNOSIS FOR NODULAR-CYSTIC GOITER – CASE REPORT
N. Vlad,R. Moldovanu,V. Filip,Cristina Preda
Jurnalul de Chirurgie , 2008,
Abstract: Branchial cysts are very rare and difficult to differentiate to nodular-cystsic goiter. We present a 51 years old women who was admitted in First Surgical Clinic Ia i, Romania, for the development of a neck mass. The ultrasound exam revealed an anechogen tumor in contact with the left thyroidian lobe. The FNAB and cytological exam were inconclusive. The intraoperative exploration established the diagnosis of branchial cyst. We performed the resection of the tumor. Postoperative course was uneventful. Conclusions: The branchial cyst is an often forgotten diagnosis. The ultrasound exam is non-specific with different patterns. Gold standard treatment is surgical resection.
SOME ASPECTS CONCERNING THE CORRELATION BETWEEN ICT AND INNOVATION IN EUROPE
CRISAN Daniela Alexandra,PREDA Ana-Maria,COCULESCU Cristina,ALTAR-SAMUEL Adam Nelu
Annals of the University of Oradea : Economic Science , 2010,
Abstract: In the context of the entire worlds efforts to start recovering from one of the worst economic crisis, finding the main drivers of growth is increasingly important. The European Commissions new proposal Europe 2020 states innovation as one of these main drivers, and promotes the development of a smart economy based on knowledge and innovation. But how innovation can be fostered? The present study focuses on the relationship between innovation and Information and Communications Technology (ICT), a supporting pillar of the smart economy. This relationship has been studied at country level using two composite indicators: one for ICT the Networked Readiness Index(NRI) published by World Economic Forum and another for Innovation the Summary Innovation Index(SII) from the European Innovation Scoreboard (EIS). The results represent a first step towards finding the best driving factors that can stimulate innovation.
E-GOVERNMENT: A DRIVING FACTOR FOR STIMULATING INNOVATION PERFORMANCE IN ROMANIA?
Preda Ana - Maria,Stanica Justina Lavinia,Crisan Daniela Alexandra,Coculescu Cristina
Annals of the University of Oradea : Economic Science , 2011,
Abstract: The development of public services is one of the priorities on the agendas of all policies, both national and European. One of the most recent concerns of the European Commission, as shown in the 2010 Innobarometer, is to find ways and develop strategies to support the innovation in the public administration sector, in the context of the continuously changing economic background. In this paper, we'll investigate the relationship between e-Government, and the overall innovation performance at national level, for some European Union countries. e-Government is already a known concept, widespread in the world, promoting the implementation of information and communication technologies in the public administration, in order to provide better public services to citizens and businesses. A main component of the e-Government concept is the 'counter reform', aimed to streamlining administrative act quickly in order to respond to the demands of citizens, businesses and government structures. Innovation in e-Government will be measured with two Eurostat indicators e-Government on-line availability and e-Government usage by individuals while for the overall innovation performance we'll use a composite indicator the Summary Innovation Index (SII) - from the Innovation Union Scoreboard (IUS). In Romania, even if the values of these indicators are not at the level of other EU countries, we can say that the situation has improved and electronic public services are being used increasingly often. The study also includes a comparison between two modest innovators: Romania and Bulgaria. Regarding the overall innovation performance, according to the 2010 Innovation Union Scoreboard ranking, Romania is the leader of the modest innovators countries, overcoming Latvia, Bulgaria and Lithuania. However, in the field of e-Government our country has major shortcomings. Romania has registered a significant progress in the years after the EU integration, followed by a setback in 2009, still having values below those of other EU countries, including Bulgaria.
On the uniform exponential stability of linear skew-product semiflows
Ciprian Preda
Journal of Function Spaces and Applications , 2006, DOI: 10.1155/2006/703620
Abstract: The problem of uniform exponential stability of linear skew-product semiflows on locally compact metric space with Banach fibers, is discussed. It is established a connection between the uniform exponential stability of linear skewproduct semiflows and some admissibility-type condition. This approach is based on the method of “test functions”, using a very large class of function spaces, the so-called Orlicz spaces.
Relaciones de parentesco en la producción familiar capitalizada del sur de Santa Fe
Preda,Graciela;
Av?? , 2010,
Abstract: the south region of santa fe responds to the requests of agricultural productive specialization through which, the country is integrated to the international markets. that specialization, centred mostly in the soybean farming, is associated to the deepening of the capital in the relations of production but maintains the condition of "family productive space". the presence of family work in the agriculture of this region is a prominent variable that defines these exploitations. in this article the relations of family relationship in the different strategies of reproduction are explained. the joint work and the association among relatives are common practices in the process of continuity on the land inherited.
DEFENSE PROGRAMS RISK MANAGEMENT FRAMEWORK
Constantin PREDA
Journal of Defense Resources Management , 2012,
Abstract: For the past years defense programs have faced delays in delivering defense capabilities and budget overruns. Stakeholders are looking for ways to improve program management and the decision making process given the very fluid and uncertain economic and political environment. Consequently, they have increasingly resorted to risk management as the main management tool for achieving defense programs objectives and for delivering the defense capabilities strongly needed for the soldiers on the ground on time and within limited defense budgets. Following a risk management based decision-making approach the stakeholders are expected not only to protect program objectives against a wide range of risks but, at the same time, to take advantage of the opportunities to increase the likelihood of program success. The prerequisite for making risk management the main tool for achieving defense programs objectives is the design and implementation of a strong risk management framework as a foundation providing an efficient and effective application of the best risk management practices. The aim of this paper is to examine the risk management framework for defense programs based on the ISO 31000:2009 standard, best risk management practices and the defense programs’ needs and particularities. For the purposes of this article, the term of defense programs refers to joint defense programs.

MORTALITY PATTERNS OF ROMA POPULATION IN OLTENIA REGION
MIHAELA PREDA
Annals of the University of Bucharest : Geography Series , 2011,
Abstract: Mortality is the only indicator that presents a series of aspects meant to emphasize both the demographic evolution of a population and its social determinants that confers it an increasing or decreasing tendency associated in most cases with a specific level of development.Mortality, through the manifestation of present variations is caused by a series of socio-economic factors such as the level of education with consequences on the attitude towards the health care, the population age, as well as by certain exogenous factors related to the geographic environment.The analysis of the general mortality among the Roma population intends to grasp a series of variables specific for this indicator; the values that the general mortality registers within the Roma population are in the trend of the values for this indicator measured for the overall population.
Relaciones de parentesco en la producción familiar capitalizada del sur de Santa Fe
Graciela Preda
Avá : Revista de Antropología , 2010,
Abstract: La región sur de la provincia de Santa Fe responde a los requerimientos de especialización productiva agrícola a través del cual el país se integra a los mercados internacionales. Dicha especialización, centrada mayormente en el cultivo de soja, está asociada a la profundización del capital en las relaciones de producción pero mantiene la condición de espacio productivo familiar. La presencia de trabajo familiar en la agricultura de esta región es una variable relevante que define a estas explotaciones. En este artículo se relatan las relaciones de parentesco en las diferentes estrategias de reproducción. El trabajo conjunto y la asociación entre parientes son prácticas comunes en el proceso de continuidad sobre la tierra heredada. The South Region of Santa Fe responds to the requests of agricultural productive specialization through which, the country is integrated to the international markets.
