The importance of pattern similarity between Müllerian mimics in predator avoidance learning
2004
Müllerian mimicry, where unpalatable prey share common warning patterns, has long fascinated evolutionary biologists. It is commonly assumed that Müllerian mimics benefit by sharing the costs of predator education, thus reducing per capita mortality, although there has been no direct test of this assumption. Here, we specifically measure the selection pressure exerted by avian predators on unpalatable prey with different degrees of visual similarity in their warning patterns. Using wild-caught birds foraging on novel patterned prey in the laboratory, we unexpectedly found that pattern similarity did not increase the speed of avoidance learning, and even dissimilar mimics shared the educatio…
Extracting multi-mode ERP features using fifth-order nonnegative tensor decomposition
2018
Background Preprocessed Event-related potential (ERP) data are usually organized in multi-way tensor, in which tensor decomposition serves as a powerful tool for data processing. Due to the limitation of computation burden for multi-way data and the low algorithm performance of stability and efficiency, multi-way ERP data are conventionally reorganized into low-order tensor or matrix before further analysis. However, the reorganization may hamper mode specification and spoil the interaction information among different modes. New method In this study, we applied a fifth-order tensor decomposition to a set of fifth-order ERP data collected by exerting proprioceptive stimulus on left and right…
Twitter en campagne politique : un exemple d’objet pour une étude interdisciplinaire en Humanités Numériques
2017
National audience; A partir de l’expérience du projet « Twitter aux Elections Européennes 2014 » développé, avec des partenaires dans 5 pays, à la Maison des Sciences de l’Homme de Dijon, la communication se concentrera sur les questions méthodologiques d’appréhension et d’exploitation d’un corpus numérique natif issu du dispositif de micro-blogging Twitter. Une attention particulière sera ainsi accordée aux opérateurs du dispositif (@, #, RT, http://) et ce qu’ils peuvent signifier en termes d’interaction médiée par ordinateur. On montrera dans quelle mesure ils rendent nécessaire une redéfinition de catégories de base en analyse du discours (qu’elle soit strictement linguistique ou davant…
Influences of geographic differentiation in the forewing warning signal of the wood tiger moth in Alaska
2014
Aposematic organisms have warning signals advertising their unpalatability to predators, and because signal efficiency is better in higher densities, positive frequency-dependent selection is expected to select against less common signals. The wood tiger moth (Parasemia plantaginis) occurs across the Holarctic and its conspicuous hindwings serve as warning signals to predators. It also has conspicuous black and white forewing patterns that could act as warning signals, or help to hide the moth by preventing predators from seeing the outline of the moth’s body (a strategy known as disruptive coloration). In Alaska, the predominant forewing pattern changes distinctly between the regions aroun…
32×32 winner-take-all matrix with single winner selection
2010
A 32 × 32 winner-take-all (WTA) matrix with single winner selection is introduced. A high-resolution gain-boosted regulated-cascode WTA circuit is used in a first competition stage. Because of the large number of competing cells the possibility of a multiple winners situation arises. A single winner is obtained by means of a digital inhibitory circuit following each WTA analogue amplifier. Simulations show that this mixed analogue-digital circuit achieves its objective with a current resolution of approximately 10 nA (0.8% of the maximum input current in the simulated case). A time response of ?s can be achieved.
The Selection and Deselection of Technocratic Ministers in Democratic Spain
2017
This chapter analyses the presence of non-political ministers in the Spanish cabinet in the democratic period since 1977, where one out of five ministers did not belong to the ruling party at the time of her appointment and one out of three can be considered as a non-political minister. By observing the selection and deselection of these individuals, it shows the cabinet dynamic behind the ministerial appointments and the differences between the more political type of ministers and those coming from outside political pathways. Despite some outstanding exceptions, non-political ministers are often recruited from outside the parliament and have fewer chances to develop a relevant ministerial …
Electoral Rules and Proportionality in Spain: Estimating the Impact of some Swedish Rules Through the 2011 Electoral Data
2016
In democratic countries policy making is always framed by many procedures and rules. Some of these rules are particularly critical for allowing more or less proportionality in legislative chambers, though the behavior of political actors also matter. The rules used for technically converting votes into political representatives often exercise such an important role in western countries. In this chapter we provide an estimation of the impact upon proportionality between seats and votes that might have resulted in the 2011 Spanish general elections if some Swedish electoral rules had been applied, ceteris paribus. As we are aware that electoral reforms favouring proportionality may hinder the…
Promotion of Reading Interests in the Study Process at the University and Lessons in School
2015
<p><em>The necessity of promoting reading interests in connection with the problems that have to be solved today and in near future in school, university and the society on the whole puts forward the task for the prospective teachers of literature to master not only theoretical knowledge in their study process but also to acquire skills necessary for their future pedagogical work so that they are able to choose the most suitable methodological approach for the interpretation of a literary work in each teaching/learning situation.</em></p>
Healthy Aging and Sentence Production: Disrupted Lexical Access in the Context of Intact Syntactic Planning.
2020
AbstractHealthy ageing does not affect all features of language processing equally. In this study, we investigated the effects of ageing on different processes involved in fluent sentence production, a complex task that requires the successful execution and coordination of multiple processes. In Experiment 1, we investigated age-related effects on the speed of syntax selection using a syntactic priming paradigm. Both young and older adults produced target sentences quicker following syntactically related primes compared to unrelated primes, indicating that syntactic facilitation effects are preserved with age. In Experiment 2, we investigated age-related effects in syntactic planning and le…
The mechanistic basis of changes in community assembly in relation to anthropogenic disturbance and productivity
2016
Anthropogenic disturbance often causes changes in communities. However, the mechanistic basis of these changes remains elusive. As all patterns in community ecology can be understood as a result of four processes (speciation, selection, drift, and dispersal), the effect of disturbance should depend on how disturbance disrupt these processes. We studied the effects of disturbance and productivity on species richness, community composition, and community dispersion (i.e., variation in community composition) in the vegetation of 120 boreal peatlands using null-model approach to determine whether community assembly processes differ between pristine and disturbed sites. Sites represented three p…
