A Comparative Study of Some Features of Higher Education in Romania, Bulgaria and Hungary

The transition from the centralized economy to the market economy has determined important changes in higher education in the countries of the former socialist bloc. In a relatively short period an impressive growth in the number of students has been recorded without taking into account the evolution of the number of pupils in high school and demographic phenomena, such as increased migration, reduced birth rate, and so on. In a medium and long time horizon the current increases in the number of students cannot be sustained. For the analysis of the data series we used a number of econometric techniques.regression models, cointegration, higher education statistics, education expenditures, ADF, unit roots

Quantitative Techniques used for the Informal Economy Analysis at National and Regional Level

The main issues in the informal economy domain are related to its definition, quantification, its position at the level of national economy and the application of econometric models to quantify its effects on economic and social development, at national and regional level. In order to evaluate the informal economy is presented the Ahumada’s model (2007). Using data series from the official statistics we made estimations of the informal economy for Romania for 2000-2009 time period. The obtained results for the ratio between cash transactions from the informal economy and the ones from the formal economy indicate that this one is situated between 24 and almost 41%. The parameter estimation for the applied regression models was realized using EViews software.Informal Economy, Econometric Models, Regional Economy

Econometric Models Used in the Analysis of the Informal Economy at the Regional Level

The disintegration of planned economies and the first elements of the market economy have resulted in a new attitude from some companies to transfer their activities to the informal economy. Assessing the probability that a company decides to conduct an economic activity can be done based on the application of the logit and probit econometric models. A series of data for different latent variables should be known for their implementation. This paper presents a number of problems related to the application of these models at the level of economic regions. Binary models are recommended because of a number of variables such as: the size of the informal economy at the level of a company, the size of unpaid taxes and duties due to their activities in the informal economy, which are not known in official statistics. These variables can be substituted to some extent by the latent variables for which data series are known.informal economy, econometric models, logit, probit

A Comparative Analysis of the Immediate Post-Operative Complications Occurring After Subtotal Gastrectomy in Patients With Gastric Carcinoma

DergiPark: 379014tmsjAims: The aims of this study were to scrutinize the immediate post-operative complications encountered after different subtotal gastrectomy procedures and to identify the safest surgical variant.Methods: In this retrospective, observational study data of 54 patients, of whom 32 were male and 22 were female,with a mean age of 65.7 years diagnosed with gastric carcinoma underwent a variant of subtotal gastrectomy in the Surgery Department of the Bucharest Clinical Emergency Hospital between January 2010 and December 2012 were recorded. The categorical statistical data was obtained with Chi-square method using GraphPad Prism and statistical significance was set at a p-value lt;0.05.Results: A total of 73 immediate post-operative complications were encountered in 23 (41.8%) patients classifiedinto local in 14 (19.2%) patients and general in 59 (80.8%) patients. The most common complication classified as local was leakage found in 5 (6.9%) patients, while the most frequent ones in general complications were secondary anemia presented in 17 (23.3%) patients and pulmonary compromise: pleural effusion in 3 (4.1%) patients. Ten associated surgical procedures were necessary, the most common being omentectomy (30%). Re-operation was deemed imperative in 5 (9.1%) cases , 4 (80%) of which were after Billroth I and 1 (20%) case was subsequent to Roux-en-Y Side-End Esophagojejunostomy. Three (5.6%) deaths were reported, 2 (66.7%) of which occurred after Roux-en-Y Side-End Esophagojejunostomy and 1 (33.3%) after the Billroth I variant.Conclusion: Billroth I yielded the highest number of complications, both local and general, compared to Hofmeister-Finsterer which generated the lowest number. The same pattern was noted with respect to the length of hospital stay. The longest operative time was recorded in Hofmeister-Finsterer and the shortest in Billroth I. A statistically significant chi-square analysis between the type of subtotal gastrectomy procedure and anastomotic leakage was obtaine

Testing Wagner’s law for Romania

This study will test Wagner’s law for Romania using both an aggregate measure of public expenditures and a disaggregated form (military expenditures). For the aggregate measure we will estimate the parameters for the models developed by Peacock-Wiseman, Gupta, Goffman, Musgrave and Mann. We will also verify the validity of the Wagner’s law in the case of military expenditures for Romania

Planul de Amenajare a Teritoriului Judeţean Vrancea

Plan of the Vrancea County is the spatial expression of the socio-economic development of the County. The study will provide a global framework for possibilities and uniform development in regional and national context. P.A.T.J. Vrancea seeks to optimize the use of natural resources, the use of work resources and the distribution of the population in order to create a permanent balance between how to exploit the natural and economic potential, of the one part, and the protection of the environment, on the other hand, through a responsible management of the territory in accordance with the principle of sustainable development. P.A.T.J. Vrancea aimed at solving specific problems of the territory in the context of efficiency, fairness, transparency and the involvement of communities in decision-making

Targeting multifunctional human ALDOA in cancer signaling

Human fructose-bisphosphate aldolase A (ALDOA) is a key enzyme in glycolysis that catalyzes the conversion of fructose 1,6-bisphosphate to glyceraldehyde 3-phosphate and dihydroxyacetone phosphate. ALDOA has also been shown to play key moonlighting roles associated with cellular structure, motility and proliferation. This aldolase isoenzyme is significantly overexpressed in a number of human tumors and has been shown to have oncogenic potential. We have demonstrated that ALDOA overexpression has further inference through cycling of hypoxia inducible transcription factor-1 (HIF-1) regulation. This feed-forward loop mediated through AMPK is a new target to consider in the irregular hypoxic environment of solid tumors. The body of work that follows presents five different methods of targeting and inhibiting ALDOA function. Using small molecule probes, the function and regulation of these iterations is characterized, towards better understanding of the role of ALDOA in cells and in cancerBiochemistr
