METHODOLOGICAL APPROACHES IN REALIZING AND APPLYING COST-BENEFIT ANALYSIS FOR THE INVESTMENT PROJECTS

Cost-benefit analysis represents the most frequent technique used for a rational allocation of resources. This modality of evaluating the expenditure programs is an attempt to measure the costs and gains of a community as a result of running the evaluatedcost-benefit analysis, social benefits, investment project, public funds, sensitivity analysis

The managerial performances evaluation through the economic value added

The goal of this work is to provide a pertinent measure of managerial performances, starting from the idea that those are real only when they assure the satisfaction of all groups, which are interested in the good evolution of the firm. The performances of a firm come from the operating activities, which has to generate big enough cash flow to accomplish the satisfactory remuneration of the creditors, to overcome all the taxes imposed by the state and to lead to the growth of the shareholders’ wealth. Measured trough economic value added the performances of the firm are dependent on the strategies, which are applied by managers.peer-reviewe

CRITICAL FACTORS IN HRD PROJECTS’ IMPLEMENTATION: EVIDENCE FROM PUBLIC UNIVERSITIES IN ROMANIA

For Romania, European Integration came with new challenges for the entire society, especially for investment project promoters, including public higher education institutions. Investments in human capital development and education have an important role in a country’s economic development and growth but, in spite of the large number of human resources development public projects being financed, major problems were identified in their implementation process, particularly factors from the macro-economic and institutional environment. Most of the current interest in this area is centered on identifying and analyzing these key factors since their understanding might lead to ensuring an improvement of the implementation process and to a project’s success. In this context, our paper’s objective is to provide a set of critical success factors for HRD projects’ implementation process by developing a framework for external environment factors’ analysis from a public project management perspective. Taking into consideration the current impact of the external environment’ factors upon projects in Romania, in this paper we chose to focus our attention only on the critical success factors of the external socio-economic, institutional, technological and cultural environment, that affect the implementation phase of a project. We started with an analysis of the Romanian context that allowed us to develop a conceptual framework. We then realized a survey on a sample of three Romanian public universities which implemented projects in human capital development by developing and applying a questionnaire to 112 persons involved as management in projects in order to identify the key factors from the external environment that affect a project’s implementation process. Results show that the most significant factors, with a negative impact, are political and economical ones while technological and cultural factors are perceived as factors with a positive influence. Our conclusions have a high informational content and can be useful for those involved in policy making and building institutional capacity in terms of human resources developmen

Numerical modelling and simulation of Koutecky-Levich equation for NADH electrocatalytic oxidation at graphite electrodes modified with a new polymeric phenothiazine

206-210A mathematical model has been developed for the electrocatalytic NADH oxidation process taking place at graphite electrodes modified with a polymer of phenothiazine formaldehyde. The electrocatalytic rate constants (kobs) have been obtained from rotating disk electrode experiments, at various concentrations of NADH and pH values of the supporting electrolyte. Using the method of linear regression, the kinetic parameters kobs[NADH]₌₀, k₊₂ and KM have been determined. Based on the results obtained, the numerical simulation of these parameters corresponding to electrocatalytic oxidation of NADH, using the modified graphite electrode, has been obtained. The experimental data overlap almost perfectly with the mathematical and numerical simulated data, proving the validity of the model

REGIONAL COMPETITIVENESS AND THE IMPACT OF EU STRUCTURAL FUNDS: THE CASE OF ROMANIA

In the context of internationalization and globalization of the world economy, regional competitiveness is thoroughly debated by politicians and policy makers, emphasizing measurable differences between development regions, without any clear political or conceptual framework. Romania’s accession to the European Union in 2007 provided an opportunity to recover in terms of regional performance and economic growth, namely structural funds as a form of nonrefundable European financial help to disadvantaged regions of member states. Our research is thus focused on analyzing the impact of structural funds’ absorption upon regional competitiveness in Romania, using extensive data over a period of seven years. Results show that EU funds critically influence the competitiveness of Romanian regions, providing reliable data for policy decision makers

Amperometric Biosensor For Ethanol Based On A Phenothiazine Derivative Modified Carbon Paste Electrode

A new amperometric biosensor for ethanol, based on carbon paste electrode modified with alcohol dehydrogenase (ADH), polyethylenimine (PEI) and using a phenothiazine derivative (DDDP; 16H,18H-dibenzo[c,1]7,9-dithia-16,18-diazapentacene) as redox mediator for NADH recycling, was developed. The biosensor response is the result of mediated oxidation of NADH, generated in the enzymatic reaction between ADH and ethanol (in the presence of NAD(+)). The biosensor sensitivity (calculated as the ratio I-max/K-M(app)) was 0.035 mA M-1 and the detection limit was 0.26 mM, while the linear response range was from 0.1 to 20 mM ethanol

Low-Cost Carbon Paste Cu(II)-Exchanged Zeolite Amperometric Sensor for Hydrogen Peroxide Detection

The aim of this work was to explore the possibility of using a Cu-exchanged zeolitic volcanic tuff (which is natural and easy to prepare and apply) for the preparation of a new low-cost carbon paste amperometric sensor for H2O2 detection. The properties of the zeolitic volcanic tuff were determined using chemical analysis, energy-dispersive X-ray spectroscopy, the specific surface area, electron microscopy, X-ray diffraction spectroscopy, and Fourier-transform infrared spectroscopy. The sensor was successfully built and operates at pH 7, at an applied potential of −150 mV Ag/AgCl/KClsat, presenting a sensitivity of 0.87 mA M−1, a detection limit of 10 µM and a linear domain up to 30 mM H2O2. These good electroanalytic parameters for H2O2 detection (a low detection limit and high sensitivity) support the possibility of using these sensors for the detection of many analytes in environmental, food and medical applications
