    Eradication of poverty and economic development are essential for a durable development. High access to production resources and the activity of effective public institutions are the most important conditions for the fight against poverty. Public and private investments in education, health care and social programs are indispensable for offering market economy integration opportunities to the paupers and to contribute to an economic development for everyone’s benefit. The satisfaction of social needs, aiming the improvement of life conditions for each person in a given society, defines an aspect of the importance of public expenses. (Economy dictionary, 1999) The amount of public expenses allocated for socio-cultural actions has an essential economic and social role and has effect on the education, the professional training and qualification, the cultural, artistic and civilisation level, the quality of medical assistance and infant mortality, the system of social protection

    Pauperism eradication and economic and social development are essential to achieve sustainable development. The increased access to productive resources and operative public institutions are the most important instruments of the fight against pauperism. Private and public investments in education, health and social programs are indispensable instruments meant to provide necessary means for the poor people to integrate in the market economy and to contribute to the economic development for the benefit of all. The Universal Declaration of Human Rights stipulates: „Everyone has the right to a standard of living adequate for the health and well-being of himself and of his family, including food, clothing, housing and medical care and necessary social services." But they are still virtual rights. The pauperism apparition, grounds and eradication are essential questions for which we should look for and fins answers, to develop and apply efficient and appropriate strategies for economic and social development of each country. The gathering of all useful information is needed in order to understand the cultural, social, economic, political and institutional realities, determining opportunities and obstacles for poor to escape from the "pauperism entrapment". "Polling is complex, fascinating and important. Pollsters give themselves the task of figuring out what millions of people are thinking about a given topic and report the results in a matter of days or even hours... Polling uses small samples to represent the views of very large numbers of people, and it is difficult for many people to believe that this process provides a true understanding of what everyone in the larger society thinks....I'm convinced that once people go behind the scenes and learn how polling really works, they will be much more likely to appreciate the valuable role polling can play in a democratic society" (Frank Newport

    On a compound approximation operator of D.D. Stancu type

    Get PDF
    In this note we consider a linear and positive compound approximation operator of D.D. Stancu type depending of several parameters; we give the expressions of this operator on the test functions, the conditions under which this operator converges to a given continuous function, an estimate of the order of approximation using the moduli of continuity and an integral representation of the remainder. Also, by using Stancu's method we find an expression for the remainder using divided differences of second order for a special case of this operator

    On an approximation operator and its Lipschitz constant

    In this note we consider an approximation operator of Kantorovich type in which expression appears a basic sequence for a delta operator and a Sheffer sequence for the same delta operator. We give a convergence theorem for this operator and we find its Lipschitz constant

    Approximation operators constructed by means of Sheffer sequences

    In this paper we introduce a class of positive linear operators by using the "umbral calculus", and we study some approximation properties of it. Let Q Q be a delta operator, and SS an invertible shift invariant operator. For fC[0,1]f\in C[0,1] we define \begin{equation*} (L_{n}^{Q,S}f)(x)= {\textstyle\frac{1}{s_{n}(1)}} \sum\limits_{k=0}^{n}{\textstyle\binom{n}{k}}p_{k}(x)s_{n-k}(1-x)f\left( \tfrac{k}{n} \right), \end{equation*} where (pn)n0(p_{n})_{n\geq0} is a binomial sequence which is the basic sequence for Q,Q, and (sn)n0(s_{n})_{n\geq0} is a Sheffer set, sn=S1pn s_{n}=S^{-1}p_{n} . These operators generalize the binomial operators of T. Popoviciu

    In this note we consider a general compound approximation operator using binomial sequences and we give a representation for its corresponding remainder term. We also introduce a more general compound approximation operator using Sheffer sequences. We provide convergence theorems for both studied operators

    In this note we introduce a compound operator depending on ss parameters using binomial sequences. We compute the values of this operator on the test functions, we give a convergence theorem and a representation of the remainder in the corresponding approximation formula. We also mention some special cases of this operator

    Order 1 autoregressive process of finite length

    Get PDF
    The stochastic processes of finite length defined by recurrence relations request additional relations specifying the first terms of the process analogously to the initial conditions for the differential equations. As a general rule, in time series theory one analyzes only stochastic processes of infinite length which need no such initial conditions and their properties are less difficult to be determined. In this paper we compare the properties of the order 1 autoregressive processes of finite and infinite length and we prove that the time series length has an important influence mainly if the serial correlation is significant. These different properties can manifest themselves as transient effects produced when a time series is numerically generated. We show that for an order 1 autoregressive process the transient behavior can be avoided if the first term is a Gaussian random variable with standard deviation equal to that of the theoretical infinite process and not to that of the white noise innovation
