Perceived Assessement Style and Learning Motivation
Elena Cocorad?,Marcela Rodica Luca,Mariela Pavalache-Ilie
Bulletin of the Transilvania University of Bra?ov. Series VII : Social Sciences and Law , 2009,
Abstract: The assessment behaviour of the teacher plays a key role in giving students feedback on their performance and enhancing learning motivation. According to orientation of the evaluation and the level of exigency, four assessment styles are described: normative, formative, popular and conventional.The research was conducted on 394 students aged 16-18 years, 253 girls and 141 boys, in 16 classes of upper higher secondary schools in the city of Brasov, and the chosen subject was English language. The perceived evaluative styles of five teachers were measured, by students in 2-3 classes for each of them, in relationship with their learning motivation. The results show that the extrinsic motivation- reward is associated with the perception of the style as lenient, the perceived performance is associated with norm-oriented. There are differences between the evaluative style perceptions of the students in the same class according to their learning performances.
The candidates’ counselling in the validation of informal and nonformal learning
E. COCORADA,M. PAVALACHE-ILIE,C. PACQUOLA
Bulletin of the Transilvania University of Bra?ov. Series VII : Social Sciences and Law , 2012,
Abstract: The validation of the competences acquired other than by formal means is a current preoccupation at national and European policies level, an opportunity for the young and the adult people alike, a desire, but at the same time a reality of everyday life. The optimal conducting of the validation of nonformal and informal learning entails, according to the European documents, the supporting of candidates. The article presents, in its first part three case studies from different national contexts, Romania, France and Italy, focused on the counselling activity, In its second part, the article analyses the perception of a counselling framework possibly to be implemented in the human resources departments of Romanian companies as a complementary manner to the counselling offered by accredited evaluation centres.
Simplifying Stochastic Mathematical Models of Biochemical Systems  [PDF]
Silvana Ilie, Samaneh Gholami
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.41A038
Abstract:

Stochastic modeling of biochemical reactions taking place at the cellular level has become the subject of intense research in recent years. Molecular interactions in a single cell exhibit random fluctuations. These fluctuations may be significant when small populations of some reacting species are present and then a stochastic description of the cellular dynamics is required. Often, the biochemically reacting systems encountered in applications consist of many species interacting through many reaction channels. Also, the dynamics of such systems is typically non-linear and presents multiple time-scales. Consequently, the stochastic mathematical models of biochemical systems can be quite complex and their analysis challenging. In this paper, we present a method to reduce a stochastic continuous model of well-stirred biochemical systems, the Chemical Langevin Equation, while preserving the overall behavior of the system. Several tests of our method on models of practical interest gave excellent results.

Automatic Simulation of the Chemical Langevin Equation  [PDF]
Silvana Ilie, Monjur Morshed
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.41A036
Abstract:

Biochemical systems have important practical applications, in particular to understanding critical intra-cellular processes. Often biochemical kinetic models represent cellular processes as systems of chemical reactions, traditionally modeled by the deterministic reaction rate equations. In the cellular environment, many biological processes are inherently stochastic. The stochastic fluctuations due to the presence of some low molecular populations may have a great impact on the biochemical system behavior. Then, stochastic models are required for an accurate description of the system dynamics. An important stochastic model of biochemical kinetics is the Chemical Langevin Equation. In this work, we provide a numerical method for approximating the solution of the Chemical Langevin Equation, namely the derivative-free Milstein scheme. The method is compared with the widely used strategy for this class of problems, the Milstein method. As opposed to the Milstein scheme, the proposed strategy has the advantage that it does not require the calculation of exact derivatives, while having the same strong order of accuracy as the Milstein scheme. Therefore it may be used for an automatic simulation of the numerical solution of the Chemical Langevin Equation. The tests on several models of practical interest show that our method performs very well.

Efficient computation of spaced seeds
Silvana Ilie
BMC Research Notes , 2012, DOI: 10.1186/1756-0500-5-123
Abstract: SpEED uses a hill climbing method based on the overlap complexity heuristic. We propose a new algorithm for this heuristic that improves its speed by over one order of magnitude. We use the new implementation to compute improved seeds for several software programs. We compute as well multiple seeds of the same weight as MegaBLAST, that greatly improve its sensitivity.Multiple spaced seeds are being successfully used in bioinformatics software programs. Enabling researchers to compute very fast high quality seeds will help expanding the range of their applications.The most frequently used tools in bioinformatics are those searching for similarities, or local alignments, between biological sequences. This problem can be solved exactly using the dynamic programming algorithm of Smith-Waterman in quadratic time. Many instances, including all database searches, are too large for this approach to be feasible and heuristic algorithms are used instead [1,2]. The most widely used program in bioinformatics, BLAST [2,3], is one such tool. It uses the so-called "hit and extend" approach: a hit consists of 11 consecutive matches between two sequences and represents a potential local alignment. The hit is then extended both ways in search for similarity.It is clear that not all local alignments have to include an identical stretch of length 11. It has been already noticed in [4] and then again in [5] that requiring that the matches are not consecutive increases the chances of finding alignments. The idea of optimizing the way the required matches are placed has been investigated in [6,7], the latter having used it in a similarity search software, PatternHunter. Much work has been dedicated to spaced seeds. For a survey of earlier work, we refer the reader to [8].The 11 consecutive matches of BLAST are called a contiguous seed, denoted 11111111111 (for 11 consecutive matches), whereas the one of PatternHunter is a spaced seed, 111*1**1*1**11*111; a 1 represents a match and * a don
The inheritance rights of the surviving spouse provided by the romanian law
Urs,Ilie;
Revista de derecho (Valparaíso) , 2009, DOI: 10.4067/S0718-68512009000100005
Abstract: in the old romanian law succession, the transmission was governed by legislation that was under the influence of roman law. the surviving spouse was quite at a disadvantage compared to the blood relatives of the defunct. the unfair succession situation of the surviving spouse was the object of vehement criticism in the romanian doctrine. nowadays, the inheritance rights of the surviving spouse are regulated by law nr. 319 of 10th june 1944 for the inheritance right of the surviving spouse that implicitly abrogated the dispositions of article 679, 681-684 of the romanian civil code. thus, according to law nr. 319 of 10th june 1944, the surviving spouse has three distinctive succession rights: i) a general inheritance right, in competition with any of the classes of heirs i-iv; ii) a special inheritance right over the movable goods and objects belonging to the household and over the wedding gifts; iii) a temporary right of occupancy of the house.
The Sale with Repurchase Clause
Urs,Ilie;
Revista de derecho (Valparaíso) , 2010, DOI: 10.4067/S0718-68512010000200002
Abstract: the sale with repurchase clause was regulated in 1864 by the civil code, within the meaning of articles 1371-1387, as a variety of sale affected by a cancellation condition. the sale with repurchase clause was frequently used in practice in order to breach the public provisions of article 1689 of the romanian civil code, on mortgage matters. taking into consideration that the sale with repurchase clause was actually a way to breach the provisions of article 1689 of the romanian civil code, giving birth to a lot of abuses on the part of the creditors, the romanian legislator decided to prohibit this type of sale. we also consider that, de lege ferenda, the implementation of a new prohibition law of the sale with repurchase clause is both necessary and useful.

Journal of Defense Resources Management , 2010,
Abstract: We initiated our endeavor staring from an undisputed reality, that is, NATO changes its strategies and, implicitly, concepts, according to the developments occurred in the international security environment, in order to be able to respond to any challenge operatively and adequately. We would like to emphasize that regardless of the concepts formulation and application, the Organization’s fundamental values, and particularly its purely defensive character and the principle of collective defense do not alter.
THE NEW STRATEGIC CONCEPT NATO 2010
Marin ILIE
Journal of Defense Resources Management , 2011,
Abstract: NATO (The North Atlantic Treaty Organization) – OTAN (Organisation du Traité de l’Atlantique Nord) has been, since its estabslishment, oustandingly receptive to the international security environment developments and has always altered its strategy and strategic concepts in order to meet the afferent challenges, with an emphasis on its purely defensive character. The most favorable moment of this kind have been its summits: Rome (1991), Washington (1999) and Lisbon (2010), on which our paper will focus. The greats mutations in the last decade have called for the creation of the new strategic concept NATO 2010, developed in the Lisbon summit declaration of 19-20 November 2010.

Studia Universitatis Vasile Goldis Arad, Seria Stiinte Economice , 2011,
Abstract: In the development and functioning process of the economy, the financing of current andinvestment activities is a key factor, the mobilization of necessary funds being possible bythe existence of financial markets. In the financial markets, public treasury plays a key role.The economic crisis has left economies without cash and the banking system was unable tosecure, through the mechanism of credit, the necessary resources for the normal functioningof economy. In these circumstances the Public Treasury must take seriously intoconsideration, as an option for the future, the development of banking operations and toattract available state funds on the financial markets.
