    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

Una cartografia completa de les experiĂšncies en mediaciĂł en tots els Ă mbits socials, de les escoles als hospitals, de les empreses als nuclis familiars, de la mediaciĂł comunitĂ ria als conflictes de consum o laborals, de la mediaciĂł penal a la mediambiental.

La conjunciĂł de les fotografies en relleu i dels estudis mĂ©s teĂČrics han fet possible la reflexiĂł ulterior, les interpretacions crĂ­tiques i, en darrer terme, les conclusions i les recomanacions, que ens ajudaran a progressar. La mediaciĂł permet detenir l'escalada dels conflictes i sostreure'ls de la resoluciĂł judicial, per implicar les parts i fer-les protagonistes actives de les solucions a quĂš arribin. Des del Departament de JustĂ­cia, ens interessa superar l'excessiva judicialitzaciĂł dels conflictes -insatisfactĂČria per a tothom- i promoure instruments que facilitin, de manera Ă gil perĂČ amb totes les garanties, la intel·ligĂšncia dels problemes i, a partir d'aquĂ­, la fixaciĂł de les millors solucions per a les parts implicades, que elles mateixes hauran construĂŻt

    Monitoring seasonal influenza epidemics is the corner stone to epidemiological surveillance of acute respiratory virus infections worldwide. This work aims to compare two sentinel surveillance systems within the Daily Acute Respiratory Infection Information System of Catalonia (PIDIRAC), the primary care ILI and Influenza confirmed samples from primary care (PIDIRAC-ILI and PIDIRAC-FLU) and the severe hospitalized laboratory confirmed influenza system (SHLCI), in regard to how they behave in the forecasting of epidemic onset and severity allowing for healthcare preparedness. Epidemiological study carried out during seven influenza seasons (2010-2017) in Catalonia, with data from influenza sentinel surveillance of primary care physicians reporting ILI along with laboratory confirmation of influenza from systematic sampling of ILI cases and 12 hospitals that provided data on severe hospitalized cases with laboratory-confirmed influenza (SHLCI-FLU). Epidemic thresholds for ILI and SHLCI-FLU (overall) as well as influenza A (SHLCI-FLUA) and influenza B (SHLCI-FLUB) incidence rates were assessed by the Moving Epidemics Method. Epidemic thresholds for primary care sentinel surveillance influenza-like illness (PIDIRAC-ILI) incidence rates ranged from 83.65 to 503.92 per 100.000 h. Paired incidence rate curves for SHLCI-FLU/PIDIRAC-ILI and SHLCI-FLUA/PIDIRAC-FLUA showed best correlation index' (0.805 and 0.724 respectively). Assessing delay in reaching epidemic level, PIDIRAC-ILI source forecasts an average of 1.6 weeks before the rest of sources paired. Differences are higher when SHLCI cases are paired to PIDIRAC-ILI and PIDIRAC-FLUB although statistical significance was observed only for SHLCI-FLU/PIDIRAC-ILI (p-value Wilcoxon test = 0.039). The combined ILI and confirmed influenza from primary care along with the severe hospitalized laboratory confirmed influenza data from PIDIRAC sentinel surveillance system provides timely and accurate syndromic and virological surveillance of influenza from the community level to hospitalization of severe cases
