Abstract In many species, agonistic interactions result in social relationships that are stable over time. In Syrian hamsters, two unfamiliar males that are placed together will fight vigorously and a clear winner/loser relationship is usually established. In subsequent interactions, the loser will flee soon after detecting the familiar winner. Here we tested the hypothesis that losing a fight with a conspecific will affect future agonistic interactions not only toward that individual (i.e., the familiar winner) but also toward unfamiliar conspecifics. To test this hypothesis we paired two Syrian hamster males in three trials on one day in which the loser had the opportunity to escape the winner. The next day the loser was paired with an unfamiliar male, also for three trials. If he lost again, he was tested on a third day with a third unfamiliar male. Subjects were those males that were losers on all three days. The latency to escape on the first trial on Days 2 and 3 was significantly shorter than on the first trial on Day 1, indicating that losing against the first male affected the response toward unfamiliar males. However, the latency to escape on the first trial on Days 2 and 3 was significantly longer than that on the third trial on the preceding day, indicating that a loser treats unfamiliar males differently than a familiar winner. These results suggest that a defeat during an interaction with one male affects later agonistic behavior towards other, unfamiliar males.

Stock market movements are affected by numerous factors making it one of the most challenging problems for forecasting. This article attempts to predict the direction of movement of stock and stock indices. The study uses three classifiers - Artificial Neural Network, Random Forest and Support Vector Machine with four different representation of inputs. First representation uses raw data (open, high, low, close and volume), The second uses ten features in the form of technical indicators generated by use of technical analysis. The third and fourth portrayal presents two different ways of converting the indicator data into discrete trend data. Experimental results suggest that for raw data support vector machine provides the best results. For other representations, there is no clear winner regarding models applied, but portrayal of data by the proposed approach gave best overall results for all the models and financial series. Consistency of the results highlight the importance of feature generation and right representation of dataset to machine learning techniques.

Recent scholarship has cautioned us that censorship does not require a censor, nor can it be described merely as the repression of information by power. Censorship can be discursively productive, and historically it has worn many guises. This article treats a case in which state censorship practices were unstable, their execution uncertain, and their target cunning, if ultimately open to compromise. Sparked by an antiaristocratic short story in Ernst Keil'sGartenlaube(arbor, bower), the most widely read German periodical of the era, theAmazonaffair involved not only its namesake ship—the Prussian S.M.S.Amazon(Amazone), a wooden corvette that sank in a storm off the coast of Holland in 1861—but an extraordinary confrontation between the conservative Prussian state and the liberal popular press. From the misstep of a weekly family magazine arose a multiyear press ban and a struggle over liberal-democratic public opinion in Germany. If no clear winner emerged from theAmazonaffair, the episode nonetheless speaks to the malleability of German political culture at a moment of profound transition, as well as to the ability of the state to shape it.

Abstract Motivation A core task of genomics is to identify the boundaries of protein coding genes, which may cover over 90% of a prokaryote's genome. Several programs are available for gene finding, yet it is currently unclear how well these programs perform and whether any offers superior accuracy. This is in part because there is no universal benchmark for gene finding and, therefore, most developers select their own benchmarking strategy. Results Here, we introduce AssessORF, a new approach for benchmarking prokaryotic gene predictions based on evidence from proteomics data and the evolutionary conservation of start and stop codons. We applied AssessORF to compare gene predictions offered by GenBank, GeneMarkS-2, Glimmer and Prodigal on genomes spanning the prokaryotic tree of life. Gene predictions were 88–95% in agreement with the available evidence, with Glimmer performing the worst but no clear winner. All programs were biased towards selecting start codons that were upstream of the actual start. Given these findings, there remains considerable room for improvement, especially in the detection of correct start sites. Availability and implementation AssessORF is available as an R package via the Bioconductor package repository. Supplementary information Supplementary data are available at Bioinformatics online.

Résumé. L'apparence des politiciens, leur représentation visuelle pendant un débat télévisé a-t-elle un impact sur l'évaluation que font d'eux les électeurs? Le contexte d'écoute joue-t-il sur l'identification du gagnant de la confrontation? Le niveau de sophistication politique et la fermeté de l'identité partisane de l'électeur limitent-ils l'effet de la représentation visuelle des politiciens dans son évaluation de leurs performances oratoires? S'inspirant du débat théorique qui secoue la discipline depuis la diffusion du premier débat Kennedy-Nixon en 1960, cet article présente les données tirées d'une expérience menée auprès d'électeurs québécois lors de la diffusion du débat francophone de l'élection fédérale canadienne de 2000. L'analyse démontre que la représentation visuelle des politiciens et le contexte d'écoute du débat amènent les participants à évaluer différemment la performance des politiciens et agissent également sur la capacité des électeurs à identifier clairement le vainqueur du débat télévisé. Les données indiquent de plus que la fermeté de l'identité partisane agit comme rempart aux effets de la représentation visuelle sur l'évaluation des politiciens par les téléspectateurs, alors que le niveau de sophistication des électeurs, contrairement aux attentes théoriques, ne joue pas ce rôle. Tout comme le contenu de leurs interventions verbales, les composantes de la représentation visuelle des acteurs politiques représentent des pistes d'information qui alimentent également la réflexion des électeurs lors de l'écoute d'un débat télévisé.Abstract. Does a politician's appearance, visual representation, during a televised debate influence voters' evaluations of her performance? Does the listening context of the debate impact a voter's capacity to identify a clear winner? Are political sophistication and partisanship strong barriers to the potential effects of politicians' images on voters' evaluations of their performance? Adding a Canadian perspective to the ongoing theoretical debate on the actual impact of leaders' visual representation in televised debates on voter preferences, launched in 1960 by preliminary assesments of the first Kennedy-Nixon debate, this article presents data collected during an experiment conducted with a sample of Québec voters during the broadcast of the French language leaders' debate of the 2000 Canadian federal election. The study shows that the leaders' visual representation during the debate and the listening context of the event bring voters to evaluate politicians participating in the broadcast differently and play on voters' capacity to easily identify a clear winner of the televised confrontation. Furthermore, our analysis indicates that partisanship is a strong barrier to the effect of visual representation in voters' evaluations of the leaders but that political sophistication, contrary to theoretical expectations, is not. Like verbal arguments brought forward by the politicians in a televised debate, their visual representation also carries information cues that help define voters' evaluations of the leaders participating in the broadcast.
