Based on a bibliographic review, the article identifies and offers a critical analysis of scientific production by the public health field in Brazil on genetically modified organisms and food (in)security. Of the 716 articles found on the portals of the Scientific Electronic Library Online (SciELO) and the Coordinating Agency for the Development of Higher Education (Capes), only 8 address the f...

Blind identification of MIMO FIR systems has widely received attentions in various fields of wireless data communications. Here, we use Particle Swarm Optimization (PSO) as the update mechanism of the well-known inverse filtering approach and we show its good performance compared to original method. Specially, the proposed method is shown to be more robust against lower SNR scenarios or in case...

We present a modified version of the polarimetric whitening filter (PWF) for target detection in single-look complex images captured by polarimetric synthetic aperture radar (PolSAR). The modified version enables the derivation of the sampling distribution of the PWF under several product model distributions for the polarimetric scattering vector. Specificly, a constant false alarm rate (CFAR) ...

This study compares the explanatory power of Martin Fishbein's and Icek Ajzen's theory of reasoned action, Icek Ajzen's theory of planned behavior, and a modified version of the theory of planned behavior, which includes a measure of moral obligation, to predict insurance agents' ethical intentions towards their clients. Two hundred and forty-five insurance agents in the U.S. were surveyed, wit...

In this paper, we make a survey of Distance Vector Multicast Routing Protocol (DVMRP) andfind that it is not optimal in the aspect of network cost (NC). Therefore, we propose a modified version of DVMRP, called “Group Membership Near First-DVMRP” (GMNF-DVMRP), to decrease the NC of the multicast tree formed by DVMRP. A simulation is implemented to compare our modified version and the original D...
