In two studies, participants read persuasive messages introduced by an attractive (Study 1) or likeable (Study 2) source before completing measures of implicit and explicit evaluations. The persuasive messages were in favor of an unfamiliar brand of facial soap (Study 1) and the implementation of comprehensive examinations at the participants’ university (Study 2). Results showed that persuasiv...

Three experiments investigate the role of expertise as a moderator of the relationship between implicit and explicit measures of attitudes. Prior research seems to suggest that greater expertise with an attitude object should lead to stronger implicit-explicit correlations. However, a cognitive view of expertise can also predict a weaker implicit-explicit relation. We lay out a framework that h...

We propose a new principle for recognizing fingerspelling sequences from American Sign Language (ASL). Instead of training a system to recognize the static posture for each letter from an isolated frame, we recognize the dynamic gestures corresponding to transitions between letters. This eliminates the need for an explicit temporal segmentation step, which we show is error-prone at speeds used ...

We propose second-order implicit-explicit (IMEX) time-stepping schemes for nonlinear fractional differential equations with fractional order 0 < β < 1. From the known structure of the nonsmooth solution and by introducing corresponding correction terms, we can obtain uniformly second-order accuracy from these schemes. We prove the convergence and linear stability of the proposed schemes. Numeri...

A user’s interest in a web page can be estimated by unobtrusively (implicitly) observing his or her behaviour rather than asking for feedback directly (explicitly). Implicit methods are naturally less accurate than explicit methods, but they do not waste a user’s time or effort. Implicit indicators of a user’s interests can also be used to create models that change with a user’s interests over ...

A new implicit method has been presented for solving singular initial value problems. The formula has derived in such a way that it excludes the singular point. The method is illustrated by suitable examples (first and second order). To check the results the approximate solutions have been compared to exact solutions KeywordsSingular initial value problems; Lane-Emden equations; Emden-Fowler eq...

Abstract: We consider three level difference replacements of parabolic equations focusing on the heat equation in two space dimensions. Through a judicious splitting of the approximation, the scheme qualifies as an alternating direction implicit (ADI) method. Using the well known fact of the parabolic-elliptic correspondence, we shall derive a two stage iterative procedure employing a fractiona...

In the standard approach, particle methods for the Boltzmann equation are obtained using an explicit time discretization of the spatially homogeneous Boltzmann equation. This kind of discretization leads to a restriction on the discretization parameter as well as on the diierential cross section in the case of the general Boltzmann equation. Recently, it was shown, how to construct an implicit ...

Over the last few years, Tanzania has witnessed an increased usage and awareness of e-Government services. This is welcome news to all stakeholders in ensuring that services offered by the government and communications between the government and citizens are efficient and effective. Despite the good news, the reality in most cases has been that the e-Government projects are implemented as techn...

In the last years the interest in computer simulations of radioactive waste scenarios has increased. In this article we present numerical simulations with the software package TRAPRO. We consider a system of convection-diffusion-reaction-equations, that we coupled by their reaction terms. We present a new discretization method that improves the explicit discretization for the transportand react...
