Arabic verbless sentences: is there a null VP?

Este trabajo pretende describir y analizar el fenómeno de la ausencia de verbo copulativo en tiempo presente en las oraciones sin verbo en árabe. Por regla general, se asume que, en árabe, las oraciones sin verbo contienen un verbo copulativo nulo o elidido. Este estudio rebate dicho supuesto y propone que, en consonancia con las bases de la sintaxis minimista (expresadas inicialmente en Chomsky 1993, 1995), las oraciones sin verbo revelan ausencia de V y, por lo tanto, de VP. La razón es que la estructura objeto de estudio presenta dos posibilidades para expresar el tiempo presente: una mediante la ausencia de verbo, y otra que conlleva la presencia de verbo copulativo con fl exión de tiempo. Palabras clave: oración sin verbo, verbo copulativo nulo, predicación, caso. The aim of this paper is to describe and analyze the absence of present tense verbal copula in Arabic verbless sentences. The Standard assumption is that Arabic verbless sentences contain a null or deleted copula. The present study argues contra this assumption. It proposes, building on the framework of minimalist syntax (fi rst proposed by Chomsky 1993, 1995), that there is no V and hence no VP in verbless sentences since the relevant construction has two alternatives to express the present tense interpretation: one is achieved without a verb and the other with a verb (copula) infl ected for tense

Inverse source problems for degenerate time-fractional PDE

In this paper, we investigate two inverse source problems for degenerate time-fractional partial differential equation in rectangular domains. The first problem involves a space-degenerate partial differential equation and the second one involves a time-degenerate partial differential equation. Solutions to both problem are expressed in series expansions. For the first problem, we obtained solutions in the form of Fourier-Legendre series. Convergence and uniqueness of solutions have been discussed. Solutions to the second problem are expressed in the form of Fourier-Sine series and they involve a generalized Mittag- Leffler type function. Moreover, we have established a new estimate for this generalized Mittag-Leffler type function. The obtained results are illustrated by providing example solutions using certain given data at the initial and final time.Comment: 12 pages, 8 figure

CUSTOMER SATISFACTION MEASUREMENT MODELS: GENERALISED MAXIMUM ENTROPY APPROACH

This paper presents the methodology of the Generalised Maximum Entropy (GME) approach for estimating linear models that contain latent variables such as customer satisfaction measurement models. The GME approach is a distribution free method and it provides better alternatives to the conventional method; Namely, Partial Least Squares (PLS), which used in the context of costumer satisfaction measurement. A simplified model that is used for the Swedish customer satis faction index (CSI) have been used to generate simulated data in order to study the performance of the GME and PLS. The results showed that the GME outperforms PLS in terms of mean square errors (MSE). A simulated data also used to compute the CSI using the GME approach.Generalised Maximum Entropy, Partial Least Squares, Costumer Satisfaction Models.

Inverse Problems of a Fractional Differential Equation with Bessel Operator

Inverse initial and inverse source problems of a time-fractional differential equation with Bessel operator are considered. Results on existence and uniqueness of solutions to these problems are presented. The solution method is based on series expansions using a set of Bessel functions of order zero. Convergence of the obtained series solutions is also discussedComment: 11 pages, No figure

Digital age: challenges for libraries

Information technology and globalization are the two most influential forces of the modern times. IT has given new meanings to the transmission, dissemination and storage of information; whereas globalisation is reducing the importance of geographical boundaries. Libraries as an important social institution have been affected by these changes. Information retrieval, information storage and information transmission are the core competencies of the libraries. Digital age characterized by efficient graphic user interface, digital imaging, efficient transfer and storage of texts, is presenting important challenges for the libraries. Information privacy, copyrights, and information security are some of the challenging issues faced by the libraries in digital age. This paper is an attempt to present as well as to discuss the implications of these issues so that strategies can be devised to address them effectively and efficiently
