The translation of web content into Libras (Lingua Brasileira de Sinais – Brazilian Sign Language), although adequate, cannot always be implemented, due to its high cost. Thus, the present study aims to identify and propose solutions for the potential communication breakdowns in the interaction of bilingual deaf users in corporate systems on the web. The analysis of the interaction took place a...

Collaborative systems are growing more and more popular. However, evaluating this type of systems is still a difficult task. Many evaluation methods have been proposed to deal with this challenge, but most of them are not yet consolidated. Semiotic Engineering is an explanatory theory about HCI that proposes three different methods that can be applied to evaluate collaborative systems: MIS, MAC...

In this paper, we show that Arrow’s well-known impossibility theorem is instrumental in bringing the ongoing discussion about verisimilitude to amore general level of abstraction. After some preparatory technical steps, we show that Arrow’s requirements for voting procedures in social choice are also natural desiderata for a general verisimilitude definition that places content and likeness con...

The observed phenomena in real sound environment system often contain uncertainty such as the additional external noise with unknown statistics. Furthermore, there is complex nonlinear relationship between the specific signal and the observations, and it cannot be exactly expressed in any definite functional form. In these situations, it is one of reasonable analysis methods to treat the object...

This review focuses on the ways in which the objectification of individuals and groups of people, as well as the self-objectification that typically develops from such treatment, is implicated in positive and negative societal change. Four areas are reviewed: (a) objectification (including dehumanization, infra-humanization, dehumanized perception, sexualization, and colonialism), (b) self-obje...

Characterizing the Instrumental Variable Identifying Assumption as Sample Selection Conditions We build on Rosenzweig and Wolpin (2000) and Keane (2010) and show that in order to fulfill the Instrumental variable (IV) identifying moment condition, a policy must be designed so that compliers and non-compliers either have the same average error term, or have an error term ratio equal to their rel...

A single and self-contained method for determining the crystallite-size distribution and shape from experimental x-ray line profile data is presented. We have shown that the crystallite-size distribution can be determined without assuming a functional form for the size distribution, determining instead the size distribution with the least assumptions by applying the Bayesian/MaxEnt method. The ...

The Inequality-Growth Plateau We examine the (potentially nonlinear) relationship between inequality and growth using a method which does not require an a priori assumption on the underlying functional form. This approach reveals a plateau completely missed by commonly used (nonlinear) parametric approaches the economy first expands rapidly with a large decline in inequality, plateaus when ineq...
