Extreme weights in Steinhaus triangles

Let {0=w0<w1<w2<…<wm0=w0<w1<w2<…<wm} be the set of weights of binary Steinhaus triangles of size n , and let Wibe the set of sequences in F2n that generate triangles of weight wi. In this paper we obtain the values of wi and the corresponding sets Wi for i¿{2,3,m}i¿{2,3,m}, and partial results for i=m-1i=m-1.Peer ReviewedPostprint (author's final draft

Induced aggregation operators in decision making with the Dempster-Shafer belief structure

We study the induced aggregation operators. The analysis begins with a revision of some basic concepts such as the induced ordered weighted averaging (IOWA) operator and the induced ordered weighted geometric (IOWG) operator. We then analyze the problem of decision making with Dempster-Shafer theory of evidence. We suggest the use of induced aggregation operators in decision making with Dempster-Shafer theory. We focus on the aggregation step and examine some of its main properties, including the distinction between descending and ascending orders and different families of induced operators. Finally, we present an illustrative example in which the results obtained using different types of aggregation operators can be seen.aggregation operators, dempster-shafer belief structure, uncertainty, iowa operator, decision making

Health care utilization among immigrants and native-born populations in 11 European countries. Results from the Survey of Health, Ageing and Retirement in Europe

Objective: This study examines health care utilization of immigrants relative to the native-born populations aged 50 years and older in eleven European countries. Methods. We analyzed data from the Survey of Health Aging and Retirement in Europe (SHARE) from 2004 for a sample of 27,444 individuals in 11 European countries. Negative Binomial regression was conducted to examine the difference in number of doctor visits, visits to General Practitioners (GPs), and hospital stays between immigrants and the native-born individuals. Results: We find evidence those immigrants above age 50 use health services on average more than the native-born populations with the same characteristics. Our models show immigrants have between 6% and 27% more expected visits to the doctor, GP or hospital stays when compared to native-born populations in a number of European countries. Discussion: Elderly immigrant populations might be using health services more intensively due to cultural reasons.count data, physician services, immigration.

Ciudadanía y universidad

Este artículo analiza la relación entre política y universidad a través del significado de la ciudadanía como concepto articulador de las relaciones entre el individuo y la vida pública. El modo de entender la ciudadanía en el mundo contemporáneo puede ser considerado como herencia de la Revolución. El artículo describe la génesis histórica del concepto postrevolucionario de ciudadanía y el modo cómo sus características esenciales afectan a la universidad contemporánea para concluir que en este contexto sociopolítico, la universidad, precisamente por su vocación universalista, debe mantener una tensión frente a la política que hace de ella una institución necesaria y paradójicamente “contracultural”

Presentación

This presentation analyzes in a general way the relationship between politics and conflict. The main argument is based on Carl Schmitt’s criterion for the definition of politics. In doing so, I introduce the central points of the different articles of this volume
