Computing Sum of Products about the Mean with Pairwise Algorithms
1997
We discuss pairwise algorithms, a kind of computational algorithm which can be useful in dynamically updating statistics as new samples of data are collected. Since test data are usually collected through time as individual data sets, these algorithms would be profitably used in computer programs to treat this situation. Pair-wise algorithms are presented for calculating the sum of products of deviations about the mean for adding a sample of data (or removing one) to the whole data set.
Proyecto de intervención antropológica en el sepulcrodel canciller villaespesa (catedral de tudela). Crónica de un intento fallido.
2021
Goal: However, the project presented here tries, on the one hand, to focus their objectives on very specific perspectives that are linked to a matter of absolute actuality in the field of humanities research, the construction of power. From that perspective, it aims to analyze the use of the death as an instrument of power and representation by the dominant elites in society and in the articulation of collective political and cultural values. It also aims to orientate from a line of clear interdisciplinary work (history, art, literacy, philosophy, music, epigraphy, codicology, anthropology ect.), that can build a broader interpretive prism and deeper analysis.
Deviant Youth Groups in Italy and France: Prevalence and Characteristics
2010
International audience; This paper sets out to compare the existence of Juvenile deviant groups in both France and Italy and their characteristics. The comparison between Italy (N=5,236) and France (N=3, 353) is based on the ISRD study of the year 2006 and shows that the term "gang" is commonly used to refer to a group of friends only. The strongest associated variables in both countries to illegal acts are the acceptance of doing illegal things, taking part in delinquent acts, considering the group as a gang as well as spending a lot of time in public places. Delinquent activity of Juvenile delinquent groups varies from one country to another and the French respondents show a greater parti…
El rol del modelo de las competencias en la reconfiguración meritocrática de las pautas de negociación salarial en empresas argentinas: continuidades…
2020
The development of new models of work organization and the complementary advance of flexible guidelines for the use of the labor force had as a correlate a profound change in techniques for the evaluation of workers. Thus, the typical model of Fordism, based on qualifications, was replaced by a different one based on competencies, whereby the strong relationship of the former was abandoned with the determination of the technical knowledge required for each job to move to a system which the priority is placed in the individual attitude. The consequent individualization of performance evaluations can lead to a possible loss of objectivity. In this article we develop a theoretical comparison b…
Comparaison internationale : à la recherche de jeunes diplômés de l'enseignement supérieur compétents en informatique
2003
By 1990, tow-thirds of all the jobs available for graduates with higher educational qualifications required advanced computer skills. However, only 30% of these graduates felt that they mastered these skills sufficiently well. Many of them have had to complete their initial vocational training by taking continuing training courses. In addition, mastering computer skills usually means earning higher wages. These results were based on a survey carried out on 35000 people who had graduated in disciplines of all kinds in eleven European countries and Japan.
Nonlinear diffusion in transparent media: the resolvent equation
2017
Abstract We consider the partial differential equation u - f = div ( u m ∇ u | ∇ u | ) u-f=\operatornamewithlimits{div}\biggl{(}u^{m}\frac{\nabla u}{|\nabla u|}% \biggr{)} with f nonnegative and bounded and m ∈ ℝ {m\in\mathbb{R}} . We prove existence and uniqueness of solutions for both the Dirichlet problem (with bounded and nonnegative boundary datum) and the homogeneous Neumann problem. Solutions, which a priori belong to a space of truncated bounded variation functions, are shown to have zero jump part with respect to the ℋ N - 1 {{\mathcal{H}}^{N-1}} -Hausdorff measure. Results and proofs extend to more general nonlinearities.
Some integral type fixed point theorems in Non-Archimedean Menger PM-Spaces with common property (E.A) and application of functional equations in dyn…
2013
In this paper, we prove some integral type common fixed point theorems for weakly compatible mappings in Non-Archimedean Menger PM-spaces employing common property (E.A). Some examples are furnished which demonstrate the validity of our results. We extend our main result to four finite families of self-mappings employing the notion of pairwise commuting. Moreover, we give an application which supports the usability of our main theorem.
Regular Minimality and Thurstonian-type modeling
2009
Abstract A Thurstonian-type model for pairwise comparisons is any model in which the response (e.g., “they are the same” or “they are different”) to two stimuli being compared depends, deterministically or probabilistically, on the realizations of two randomly varying representations (perceptual images) of these stimuli. The two perceptual images in such a model may be stochastically interdependent but each has to be selectively dependent on its stimulus. It has been previously shown that all possible discrimination probability functions for same–different comparisons can be generated by Thurstonian-type models of the simplest variety, with independent percepts and deterministic decision ru…
When can association graphs admit a causal interpretation?
1994
We discuss essentially linear structures which are adequately represented by association graphs called covariance graphs and concentration graphs. These do not explicitly indicate a process by which data could be generated in a stepwise fashion. Therefore, on their own, they do not suggest a causal interpretation. By contrast, each directed acyclic graph describes such a process and may offer a causal interpretation whenever this process is in agreement with substantive knowledge about causation among the variables under study. We derive conditions and procedures to decide for any given covariance graph or concentration graph whether all their pairwise independencies can be implied by some …
Dichotomies properties on computational complexity of S-packing coloring problems
2015
This work establishes the complexity class of several instances of the S -packing coloring problem: for a graph G , a positive integer k and a nondecreasing list of integers S = ( s 1 , ? , s k ) , G is S -colorable if its vertices can be partitioned into sets S i , i = 1 , ? , k , where each S i is an s i -packing (a set of vertices at pairwise distance greater than s i ). In particular we prove a dichotomy between NP-complete problems and polynomial-time solvable problems for lists of at most four integers.
