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.
Comparing normal means: new methods for an old problem
2007
Comparing the means of two normal populations is an old problem in mathematical statistics, but there is still no consensus about its most appropriate solution. In this paper we treat the problem of comparing two normal means as a Bayesian decision problem with only two alternatives: either to accept the hypothesis that the two means are equal, or to conclude that the observed data are, under the assumed model, incompatible with that hypothesis. The combined use of an information-theory based loss function, the intrinsic discrepancy (Bernardo and Rueda 2002}, and an objective prior function, the reference prior \citep{Bernardo 1979; Berger and Bernardo 1992), produces a new solution to this…
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.
Survey of methods to visualize alternatives in multiple criteria decision making problems
2012
When solving decision problems where multiple conflicting criteria are to be considered simultaneously, decision makers must compare several different alternatives and select the most preferred one. The task of comparing multidimensional vectors is very demanding for the decision maker without any support. Different graphical visualization tools can be used to support and help the decision maker in understanding similarities and differences between the alternatives and graphical illustration is a very important part of decision support systems that are used in solving multiple criteria decision making problems. The visualization task is by no means trivial because, on the one hand, the grap…
Lower semicontinuity of weak supersolutions to the porous medium equation
2013
Weak supersolutions to the porous medium equation are defined by means of smooth test functions under an integral sign. We show that nonnegative weak supersolutions become lower semicontinuous after redefinition on a set of measure zero. This shows that weak supersolutions belong to a class of supersolutions defined by a comparison principle.
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…
Radicalization in Correctional Systems: A Scoping Review of the Literature Evaluating the Effectiveness of Preventing and Countering Interventions
2023
Although several prevention and countering radicalization programs in correctional institutions have been carried out in Europe and worldwide, little is known about their effectiveness. Thus, the current scoping review aimed at reporting on the state of the art of the literature assessing and evaluating such actions, identifying knowledge gaps, and examining methods used to assess their successfulness and impact. A total of eight studies that met eligibility criteria were reviewed after performing a search on Scopus, Web of Science, and PsychInfo (Ebsco) databases: Two studies evaluated a reintegration initiative based in the Netherlands; four focused on an Australian disengagement program;…
Italian Heroines: Literature, Gender, and the Construction of the Nation
2019
Scholarship on Italian nationhood has historically focused on heroes rather than on heroines, in line with the established gendered dialectical relationship between the female nation (who nurtures those who fight for her), and the male patriot, who both adores and possesses her. However, it is argued that Italian literary heroines prove at least as productive as heroes, if not more, when it comes to generating alternative views on the nation. This essay offers an introduction to a themed issue that aims to fill this scholarly gap in relation to ideas about the Italian nation and nationhood.
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…
The UN in the Lab
2013
We consider two alternatives to inaction for governments combating terrorism, which we term Deterrence and Prevention. Deterrence – investing in resources that reduce the impact of an attack – generates a negative externality to other governments, making their countries a more attractive objective for terrorists, while Prevention – investing in resources that reduce the ability of the terrorist organization to mount an attack – creates a positive externality by reducing the overall threat of terrorism for all. Due to the structure of this interaction, countries can benefit from coordination of policy choices, and international institutions (such as the UN) can be utilized to facilitate coor…
