The Multi-Lane Capsule Network (MLCN)

We introduce Multi-Lane Capsule Networks (MLCN), which are a separable and resource efficient organization of Capsule Networks (CapsNet) that allows parallel processing, while achieving high accuracy at reduced cost. A MLCN is composed of a number of (distinct) parallel lanes, each contributing to a dimension of the result, trained using the routing-by-agreement organization of CapsNet. Our results indicate similar accuracy with a much reduced cost in number of parameters for the Fashion-MNIST and Cifar10 datsets. They also indicate that the MLCN outperforms the original CapsNet when using a proposed novel configuration for the lanes. MLCN also has faster training and inference times, being more than two-fold faster than the original CapsNet in the same accelerator

Journalism at the Periphery

The increasing influence of actors who might not fit into traditional definitions of a journalist but are taking part in processes that produce journalism has attracted scholarly attention. They have been called interlopers, strangers, new entrants, peripheral, and emergent actors, among others. As journalism scholars grapple with how to refer to these actors, it is important to reflect on the assumptions that underlie emerging labels. These include: 1) what journalistic tasks are involved; 2) how and why these journalistic tasks are performed; 3) who is making the definition; and 4) where and when these actors are located. However, journalism being the centre of our investigation should not automatically assume that it is at the centre of social life. So, it might also be that for the technological field, journalism is at the periphery; that for these technology-oriented actors whose influence across fields is increasing, journalists and what they do are at the periphery. For a field that supposedly plays an important role in public life, this has important implications

The Redox-Sensitive Transcriptional Activator OxyR Regulates the Peroxide Response Regulon in the Obligate Anaerobe Bacteroides fragilis

The peroxide response-inducible genes ahpCF, dps, and katB in the obligate anaerobe Bacteroides fragilis are controlled by the redox-sensitive transcriptional activator OxyR. This is the first functional oxidative stress regulator identified and characterized in anaerobic bacteria. oxyR and dps were found to be divergently transcribed, with an overlap in their respective promoter regulatory regions. B. fragilis OxyR and Dps proteins showed high identity to homologues from a closely related anaerobe, Porphyromonas gingivalis. Northern blot analysis revealed that oxyR was expressed as a monocistronic 1-kb mRNA and that dps mRNA was approximately 500 bases in length. dps mRNA was induced over 500-fold by oxidative stress in the parent strain and was constitutively induced in the peroxide-resistant mutant IB263. The constitutive peroxide response in strain IB263 was shown to have resulted from a missense mutation at codon 202 (GAT to GGT) of the oxyR gene [oxyR(Con)] with a predicted D202G substitution in the OxyR protein. Transcriptional fusion analysis revealed that deletion of oxyR abolished the induction of ahpC and katB following treatment with hydrogen peroxide or oxygen exposure. However, dps expression was induced approximately fourfold by oxygen exposure in DoxyR strains but not by hydrogen peroxide. This indicates that dps expression is also under the control of an oxygen-dependent OxyR-independent mechanism. Complementation of DoxyR mutant strains with wildtype oxyR and oxyR(Con) restored the inducible peroxide response and the constitutive response of the ahpCF, katB, and dps genes, respectively. However, overexpression of OxyR abolished the catalase activity but not katB expression, suggesting that higher levels of intracellular OxyR may be involved in other physiological processes. Analysis of oxyR expression in the parents and in DoxyR and overexpressing oxyR strains by Northern blotting and oxyR*::xylB fusions revealed that B. fragilis OxyR does not control its own expression.

Effect of biofertilizers and neem oil on the entomopathogenic fungi beauveria bassiana (Bals.) vuill. and metarhizium anisopliae (Metsch.) sorok.

The in vitro fungitoxic effect of three biofertilizers, E.M.-4, Multibion Ô and Supermagro used in organic agriculture and the neem oil (Azadirachta indica A. Juss) on the entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana was studied. These products were mixed in a medium where the two fungi were inoculated, and germination, vegetative growth and conidiogenesis were assessed. The biofertilizers Supermagro and E.M.- 4 showed to be less toxic for the two fungi whereas MultibionÔ caused major inhibition on M. anisopliae, with reductions in germination (-37.74%), colony diameter (-30.26%) and conidiogenesis (-42.62%). Neem oil promoted a larger negative effect on B. bassiana, inhibiting germination (-45.27%), colony diameter (-36.62%) and conidiogenesis (-84.93%)

What Is (Fake) News? Analyzing News Values (and More) in Fake Stories

‘Fake news’ has been a topic of controversy during and following the 2016 U.S. presidential election. Much of the scholarship on it to date has focused on the ‘fakeness’ of fake news, illuminating the kinds of deception involved and the motivations of those who deceive. This study looks at the ‘newsness’ of fake news by examining the extent to which it imitates the characteristics and conventions of traditional journalism. Through a content analysis of 886 fake news articles, we find that in terms of news values, topic, and formats, articles published by fake news sites look very much like traditional—and real—news. Most of their articles included the news values of timeliness, negativity, and prominence; were about government and politics; and were written in an inverted pyramid format. However, one point of departure is in terms of objectivity, operationalized as the absence of the author’s personal opinion. The analysis found that the majority of articles analyzed included the opinion of their author or authors

A Black and White Game: Racial Stereotypes in Baseball

The current study experimentally tested stereotypes and credibility of messages associated with athletes. Participants were asked to rate photos of black and white baseball players based on stereotypes identified in previous literature. They were then given an anonymous paragraph from a newspaper that featured either a stereotype consistent or inconsistent message and asked to rate the author\u27s credibility. Black players were rated significantly higher in physical strength and natural ability, which is consistent with previous literature. However, inconsistent with previous literature, white players were not rated significantly higher in intelligence and leadership. Despite these results, when measuring credibility, this study found white-consistent stereotypes to be credible, whereas black-consistent ones were not. These results are interpreted in light of Devine\u27s model of stereotype processing and in-group, out-group bias

Poesia Hebraica Bíblica: A Relação entre Forma e Conteúdo em Juízes 4 e 5

A prosa e a poesia da Bíblia Hebraica guardam similaridades e diferenças, mas nem sempre delimitar a forma de ambas é fácil. Além disso, se a forma guarda relação com o conteúdo, pressupõe-se que ao contar a mesma história de formas diferentes (prosa e poesia) indicará um propósito distinto também. O artigo é uma análise da relação entre forma e conteúdo em Juízes 4 e 5 a partir das diferenças e similaridades entre prosa e poesia
