[more ▼] In many domains we are faced with the problem of aggregating a collection of numerical readings to obtain a mean or typical value. Such an aggregation problem is becoming more and more present in an increasing number of areas not only of mathematics or physics, but also of engineering, economical, social, and other sciences. Various aggregation functions and processes have already been proposed in the literature and many others are still to be designed to fulfill newer and newer requirements. Studies on the aggregation problem have shown that the choice of the aggregation function is far from being arbitrary and should be based upon properties dictated by the framework in which the aggregation is performed. One of the main concerns when choosing an appropriate function is to take into account the scale types of the variables being aggregated. On this issue it was observed that the general form of the aggregation function is greatly restricted if we know the scale types of the dependent and independent variables. For instance, if all the variables define a common ordinal scale, it is clear that any relevant aggregation function cannot be constructed from usual arithmetic operations, unless these operations involve only order. Thus, computing the arithmetic mean is forbidden whereas the median or any order statistic is permitted. We present a state of the art survey on the known axiomatizations of aggregation functions mapping ordinal scales into an ordinal scale. We show that, in this ordinal context, the family of possible aggregation functions is rather poor, more or less consisting of order statistics and lattice polynomials.

[more ▼] In das Bild unserer Gesellschaft der Gegenwart scheint der Mangel an Zeit fest eingebaut zu sein. Betrachtet man zum Beispiel die Werbung, fällt auf, daß der Zweck einer großen Anzahl von Produkten darin besteht, möglichst viel Zeit zu sparen. Man gewinnt den Eindruck, es gäbe für jede Person ein sehr geringes Kontingent an Zeit und eine so große Fülle von Handlungen, die sie ausführen müsse, daß es unbedingt notwendig sei, alles so schnell wie möglich zu erledigen. Trifft diese Sichtweise aber auf jedes Individuum in unserer Gesellschaft zu? Sind wir alle ständig bestrebt, alles so schnell wie möglich zu tun, um möglichst viel Zeit zu sparen? Und in welchen Verhaltensweisen äußert sich dieses Bestreben? Aus den Überlegungen, wie man der Beantwortung dieser Fragestellung näher kommen könnte, entstand die Idee, einen Fragebogen zu entwickeln, mit welchem es möglich ist, das Ausmaß der Zeitnot im Sinne einer Persönlichkeitsvariablen zu messen. Folgende Definition von Zeitnot lag dem Untersuchungsvorhaben zugrunde: Zeitnot soll das Ausmaß bezeichnen, in welchem eine Person ihr Verhalten im Sinne der Zeitersparnis ausrichtet, und sie darunter leidet, wenn sie subjektiv einen Zeitverlust erlebt oder erwartet. Der Fragebogen umfaßt 19 Items im dichotomen Antwortformat mit den Antwortalternativen „trifft zu“ und „trifft nicht zu“. Zur Ermittlung der Item-Kennwerte (Schwierigkeit, Trennschärfe) wurde eine Stichprobe von 107 Personen herangezogen. Faktorenanalytisch konnten Anhaltspunkte für vier Dimensionen des Konstrukts gefunden werden. Die Dimensionen wurden interpretiert als Terminierung (Beispiel-Item: „Wenn ich etwas mache, nehme ich mir vor, es in einer bestimmten Zeit zu schaffen.“), Ungeduld (Beispiel-Item: „Am Bankautomaten werde ich leicht ungeduldig.“), Frustration nach Nichteinhalten des Plans (Beispiel-Item: „Ich ärgere mich, wenn ich nicht alles schaffe, was ich mir vorgenommen habe.“) und Eile (Beispiel-Item: „Ich habe es meistens eilig.“). Die internen Konsistenzen der entsprechenden Subskalen lagen zwischen .69 und .86 (M = .75).

[more ▼] Contexte de la recherche : La question des inégalités de santé. La mortalité et la morbidité par AVC est, en Europe, plus fréquente dans les groupes socio-économiques défavorisés que dans ceux du haut de la hiérarchie sociale. Ces différences reflètent, à la fois, les différences sociales dans: l’exposition aux facteurs de risque ‘classiques’ d’AVC (HTA, apports alimentaires de sel et de matières grasses, tabagisme, diabète, surpoids) l’utilisation du système de soins, en particulier pour l’accès aux spécialistes et aux procédures diagnostiques, et des ressources socio-éducatives (aides, matériels). Ces inégalités entre groupes sociaux pourraient en partie s’expliquer par la part plus grande que prend le social par rapport au physique ou au fonctionnel. Ce mécanisme social à l’origine des inégalités serait possible par l’existence d’une disposition différentielle socialement acquise qui permettrait aux uns par rapport aux autres : de mieux s’approprier les bénéfices des ressources existantes (matérielles et sociales) d’avoir davantage de capacité d’accéder à l'information d’échapper aux effets délétères de certains facteurs de risque. La gravité de l’AVC influence-elle les prises en charge hospitalières, rééducatives et réadaptatives de la phase aiguë de l’AVC ? Ces dernières influencent-elles les déficiences des personnes victimes d'un AVC ? Les types de handicap et le niveau d’autonomie influencent-ils les retentissements familiaux et la qualité de vie pour le patient victime d’AVC et son aidant principal ? Les types de handicap et le niveau d’autonomie influencent-ils l’utilisation des ressources disponibles socio-sanitaires et éducatives ainsi que leur satisfaction ?

[more ▼] La survenue d’AVC est un événement majeur dans la vie de la victime et de son entourage, amenant des bouleversements considérables tant sociaux que psychoaffectifs. Notre étude a porté sur les conséquences de cet évènement sur la famille proche, notamment le conjoint, du malade qui en a été victime. L’hypothèse posée est que parmi les différentes gravités, les AVC qui ont entraîné une aphasie grave, voire totale, sont plus dramatiques que celles où les déficiences étaient seulement physiques. La question de la stigmatisation est ainsi posée : elle semble en grande partie liée à certaines représentations sociales du handicap physique et mental et à leur intériorisation par le malade et par son entourage proche. L’objectif de l’enquête quantitative était de comparer le retentissement familial et social, en particulier chez les conjoints, en fonction de la nature de l’atteinte (ici présence ou non d’une aphasie) Parmi les variables de différenciation, le fait d’être aphasique ou non à la suite de l’AVC est celle qui est la plus discriminante.

[more ▼] In the first part of this presentation we define the concept of weighted lattice polynomials as lattice polynomials constructed from both variables and parameters. We then show that, in any bounded distributive lattice, these functions can always be written in conjunctive and disjunctive normal forms. We also show that these functions include the class of discrete Sugeno integrals and that they are characterized by a remarkable median based decomposition formula. In the second part we give the cumulative distribution functions, the expected values, and the moments of weighted lattice polynomials when regarded as real functions. Since weighted lattice polynomial functions include Sugeno integrals, lattice polynomial functions, and order statistics, our results encompass the corresponding formulas for these particular functions. We then conclude with some applications of our results to the reliability analysis of coherent systems.

The classical best decision problem approach is critically reviewed. New practical principles underlying a best choice recommendation are introduced which promote the outranking kernels as candidates for best choice recommendations. Some illustrative applications were eventually shown in order to convince the audience.
