Over the past decade or so, a number of software environments have been created to support students engaged in collaborative investigations in science (e.g., Belvedere, CoVis, CSILE, SenseMaker, and WebCamile). These environments have used a variety of representations for recording information such as alternate hypotheses, empirical observations, and evidential relations (e.g., node-link graphs...

The norm of the 21 century has been decentralization as competition in the marketplace has increased significantly. Organizations commonly freelance or outsource work to other professionals or manufacturers where it can be performed at lower cost. Thus, due to the changing nature of work, there is a need to reconsider the ETHICS of the past. Based upon the new work order, changes in ETHICS are ...

This paper addresses a re-reading of the Farroupilha War (1835-1845) at IHGB from the 1920’s to the celebration of the conflict centenary in 1935, which ended up integrating it into the national historical memory. In this process, discursive and institutional strategies were triggered, regarding the political use of the past, the historiographical tradition of IHGB and the constructed intellect...

In 2008 we are celebrating the 10-th anniversary of CHES and the 30-th anniversary of the publication of the RSA paper at CACM. In this talk I will survey some of the major RSA-related papers published at CHES during the last 10 years, describe my own research on security and implementation issues, introduce some new attacks, and make predictions about the future of RSA.

for an evolution family (U(t, s))t≤s≤0 on X . We refer to [5, 12] where these equations have been introduced and to [10, 13] for concrete examples. In particular, we showed in [12] that (1.1) and the abstract Cauchy problem associated to an operator ( ,D( )) on the product space := X × L(R−,X) are “equivalent.” Since, under appropriate conditions, the operator ( ,D( )) is the generator of a str...

The testing effect is a useful method of instruction. However it has only been used sporadically as an instructional method. This study examined whether or not students perform better on average with an increased amount of tests in comparison to an average amount of tests. The study was conducted over a period of two weeks when the students received an increase of tests aligning with the state ...
