Federalism and Party Democracy in West Germany
2011
According to Gerhard Lehmbruch, there is a growing inconsistency in West Germany between the principles of a federal polity and party democracy, primarily because the former relies on bargaining, and the latter relies on majority rule as a mechanism of conflict regulation. However, comparative analyses have shown that federalism and party competition are not incompatible. Generally, federal structures are neither detrimental nor conducive to the recruitment function of parties. Competence and experience as a parliamentary leader or as a specialist is the most essential precondition for advancement to national executive positions. The integrative capacities of political parties may even be s…
Dynamic integration with random forests
2006
Random Forests (RF) are a successful ensemble prediction technique that uses majority voting or averaging as a combination function. However, it is clear that each tree in a random forest may have a different contribution in processing a certain instance. In this paper, we demonstrate that the prediction performance of RF may still be improved in some domains by replacing the combination function with dynamic integration, which is based on local performance estimates. Our experiments also demonstrate that the RF Intrinsic Similarity is better than the commonly used Heterogeneous Euclidean/Overlap Metric in finding a neighbourhood for local estimates in the context of dynamic integration of …
Linguistic intergroup bias at school : an exploratory study of black and white children in France and their implicit attitude towards another
2014
International audience; " Linguistic intergroup bias " (LIB) (Maass et al., 2000) was investigated in French elementary schools between children of the French majority group (White children of European heritage) and a French minority group (Black children from Sub-Saharan Africa). Participants (N = 360; 7–11-year-old; mean age = 10.36, SD = .85) were shown photographs presenting a target character (ingroup or outgroup) engaging in a positive behavior (e.g., a helping action) or a negative behavior (e.g., an aggressive action). Demonstrations of ingroup favoritism with no outgroup derogation were expected for White children from the majority group. These hypotheses were confirmed. Unexpected…
Cellular automaton for chimera states
2016
A minimalistic model for chimera states is presented. The model is a cellular automaton (CA) which depends on only one adjustable parameter, the range of the nonlocal coupling, and is built from elementary cellular automata and the majority (voting) rule. This suggests the universality of chimera-like behavior from a new point of view: Already simple CA rules based on the majority rule exhibit this behavior. After a short transient, we find chimera states for arbitrary initial conditions, the system spontaneously splitting into stable domains separated by static boundaries, ones synchronously oscillating and the others incoherent. When the coupling range is local, nontrivial coherent struct…
El pueblo de la Confederación suiza: su significación constitucional y composición
2016
ResumenEl pueblo, que se expresa como cuerpo electoral (o conjunto de ciudadanos que tras la mayoría de edad pueden ejercer los derechos políticos), es elemento constitutivo y constituyente de la Confederación (tanto en su dimensión federal como en la cantonal) y, a la vez, órgano supremo y primera fuente de legitimidad del ordenamiento constitucional suizo. El pueblo participa en las decisiones que comportan incorporaciones al mismo dando lugar en ocasiones a conflictos con las decisiones de las autoridades competentes.AbstractThe people who are defined as the electorate (the citizens who after the age of majority exercise in reality their political rights), are the constitutive and consti…
On Distinguishing between Reliable and Unreliable Sensors Without a Knowledge of the Ground Truth
2015
In many applications, data from different sensors are aggregated in order to obtain more reliable information about the process that the sensors are monitoring. However, the quality of the aggregated information is intricately dependent on the reliability of the individual sensors. In fact, unreliable sensors will tend to report erroneous values of the ground truth, and thus degrade the quality of the fused information. Finding strategies to identify unreliable sensors can assist in having a counter-effect on their respective detrimental influences on the fusion process, and this has has been a focal concern in the literature. The purpose of this paper is to propose a solution to an extreme…
On Solving the Problem of Identifying Unreliable Sensors Without a Knowledge of the Ground Truth: The Case of Stochastic Environments.
2017
The purpose of this paper is to propose a solution to an extremely pertinent problem, namely, that of identifying unreliable sensors (in a domain of reliable and unreliable ones) without any knowledge of the ground truth. This fascinating paradox can be formulated in simple terms as trying to identify stochastic liars without any additional information about the truth. Though apparently impossible, we will show that it is feasible to solve the problem, a claim that is counterintuitive in and of itself. One aspect of our contribution is to show how redundancy can be introduced, and how it can be effectively utilized in resolving this paradox. Legacy work and the reported literature (for exam…
Modelling Dependencies Between Classifiers in Mobile Masquerader Detection
2004
The unauthorised use of mobile terminals may result in an abuse of sensitive information kept locally on the terminals or accessible over the network. Therefore, there is a need for security means capable of detecting the cases when the legitimate user of the terminal is substituted. The problem of user substitution detection is considered in the paper as a problem of classifying the behaviour of the person interacting with the terminal as originating from the user or someone else. Different aspects of behaviour are analysed by designated one-class classifiers whose classifications are subsequently combined. A modification of majority voting that takes into account some of the dependencies …
A multiscale approach to automatic and unsupervised retinal vessel segmentation using Self-Organizing Maps
2016
In this paper an automatic unsupervised method for retinal vessel segmentation is described. Self-Organizing Map, modified Fuzzy C-Means, STAPLE algorithms and majority voting strategy were adopted to identify a segmentation of the retinal vessels. The performance of the proposed method was evaluated on the DRIVE database.
