Rational and Irrational Beliefs

Abstract: Rational emotive behaviour therapy or REBT (Ellis 2001, 2007; Ellis and Harper 1997) as it is popularly known as was developed in the 1950s by the American psychotherapist Dr. Albert Ellis.

Towards a Collaborative Disaster Management Service Framework using Mobile and Web Applications: A Survey and Future Scope

Abstract: Getting the right information at the right time and place is the key for efficient disaster management. Various mobile and web applications are now being used for collecting situational information in digital form, assessing damage, coordinating relief operations and offering different location based services to the affected communities during disaster management. This article provides a thorough investigation on popular web-based and mobile applications currently being used in different countries. Subsequently, the taxonomy of essential services needed for systematic and coordinated disaster management is formulated based on literature review and the authors' interaction with different stakeholders. An outline of a collaborative disaster management service framework is then proposed with the facility of interaction for the stakeholders through their mobile phones to avail the services in different phases of a disaster. A basic version of this framework is implemented to evaluate its effectiveness as a provider of significant actionable information to offer responsive services

A framework for the simultaneous measurement of spatial variation and temporal movement in prices in a heterogeneous country: the dynamic household regional product dummy model

Abstract: This paper contributes to the growing literature on spatial prices in large heterogeneous countries. While the literatures on spatial variation and temporal movement in prices have grown in parallel, this study marks a departure by providing a unified treatment and proposing a comprehensive framework that allows both approaches. The proposed model is based on twin extensions of the household version of the “country product dummy model” by allowing for a dynamic stochastic specification and interdependence of spatial prices of geographically adjacent regions. Tests of temporal stability and regional independence of the estimated spatial prices are proposed and applied in this paper. The paper shows that the introduction of an autoregressive error process of order one, AR(1), improves the efficiency of the estimates of parameters, urban-rural and temporal price indices under certain conditions. The Indian application points to a rich potential for using the proposed framework in cross country comparisons such as the International Comparison Program (ICP) exercises.

An exact best-first search procedure for the constrained rectangular guillotine knapsack problem

Abstract: The Constrained Rectangular Guillotine Knapsack Problem (CRGKP) is a variant of the two-dimensional cutting stock problem. In the CRGKP, a stock rectangle of dimensions (L,W) is given. There are n different types of demanded rectangles, with the ith type ri having length 1i, width wi, value vi and demand constraint bi. S must be cut using only orthogonal guillotine cuts to produce ai copies of ri, 1 ≤ i ≤ n, so as to maximize alvl + a2v2 +....+ anvn, subject to the constraints ai ≤ bi, l ≤ i ≤ n. All parameters are integers. Here a new best-first search algorithm for the CRGKP is described. The heuristic estimate function is monotone, and optimal solutions are guaranteed. Computational results indicate that this method is superior in performance to the two existing algorithms for the problem.
