Using Ordered Weighted Average for Weighted Averages Inflation

This paper presents the ordered weighted average weighted average inflation (OWAWAI) and some extensions using induced and heavy aggregation operators and presents the generalized operators and some of their families. The main advantage of these new formulations is that they can use two different sets of weighting vectors and generate new scenarios based on the reordering of the arguments with the weights. With this idea, it is possible to generate new approaches that under- or overestimate the results according to the knowledge and expertise of the decision-maker. The work presents an application of these new approaches in the analysis of the inflation in Chile, Colombia, and Argentina during 2017

Guía de práctica clínica para el manejo quirúrgico de la obesidad en adultos en el Seguro Social del Perú (EsSalud)

Background: This article summarizes the clinical practice guide (CPG) for the surgical management of obesity in adults in the Social Security of Peru (EsSalud). Objective: To provide clinical recommendations based on evidence for the surgical management of patients with obesity in EsSalud. Material and Methods: A CPG for the surgical managmente of patients with obesity in EsSalud was developed. To this end, a guideline development group (local GDG) was established, including medical specialists and methodologists. The local GDG formulated 7 clinical questions to be answered by this CPG. Systematic searches of systematic reviews and -when it was considered pertinent- primary studies were conducted in Medline and CENTRAL during 2019. The evidence to answer each of the posed clinical questions was selected. The quality of the evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. In periodic work meetings, the local GDG used the GRADE methodology to review the evidence and formulate the recommendations, points of good clinical practice, and the flowchart identification of patients with indication for bariatric / metabolic surgery and selection of the type of surgical intervention. The flowchart was designed in the final phase or last meeting based on the recommendations made previously. Finally, the CPG was approved with Resolution No. 115 – IETSI – ESSALUD – 2020. Results: This CPG addressed 7 clinical questions, divided into topics of surgical management of patients with obesity. Based on these questions, 6 recommendations were formulated (3 strong and 3 conditional), 18 BPC, and 2 flow charts. Conclusion: This article summarizes the methodology, recommendations based on evidence, and the points of good clinical practice from the CPG for the surgical management of obesity in EsSalud.Introducción: El presente artículo resume la guía de práctica clínica (GPC) para el manejo quirúrgico de la obesidad en adultos en el Seguro Social del Perú (EsSalud). Objetivo: Proveer recomendaciones clínicas basadas en evidencia para el manejo quirúrgico de la obesidad en adultos en EsSalud. Material y Métodos: Se conformó un grupo elaborador de la guía (GEG) que incluyó médicos especialistas y metodólogos. El GEG formuló 7 preguntas clínicas a ser respondidas por la presente GPC. Se realizó búsquedas sistemáticas de revisiones sistemáticas y –cuando fue considerado pertinente– estudios primarios en Medline y CENTRAL durante el 2019. Se seleccionó la evidencia para responder cada una de las preguntas clínicas planteadas. La certeza de la evidencia fue evaluada usando la metodología Grading of Recommendations Assessment, Development, and Evaluation (GRADE). En reuniones de trabajo periódicas, el GEG usó la metodología GRADE para revisar la evidencia y formular las recomendaciones, los puntos de buenas prácticas clínicas. El flujograma fue diseñado en la fase final o última reunión en base a las recomendaciones formuladas previamente. Finalmente, la GPC fue aprobada con Resolución N° 115 – IETSI – ESSALUD – 2020. Resultados: La presente GPC abordó 7 preguntas clínicas, divididas en a temas de manejo quirúrgico de pacientes con obesidad. En base a dichas preguntas se formularon 6 recomendaciones (3 fuertes y 3 condicionales), 18 BPC, y 2 flujogramas. Conclusión: El presente artículo resume la metodología, las recomendaciones basadas en evidencias, y los puntos de buena práctica clínica de la GPC para manejo quirúrgico de la obesidad en adultos en EsSalud

Prioritized Induced Heavy Operators Applied to Political Modelling

This paper presents the prioritized induced heavy ordered weighted average (PIHOWA) operator. This operator combines an unbounded weighting vector, an induced vector and a prioritized vector and can be applied to the group decision-making process where the information provided by each decision maker does not have the same importance. An application of this operator is done in governmental transparency in Mexico based on the Open Government Metric (OGM). Among the main results it is possible to visualize how the relative importance of each component can generate important change in the top 10 ranking

Series of Floor and Ceiling Functions—Part II: Infinite Series

In this part of a series of two papers, we extend the theorems discussed in Part I for infinite series. We then use these theorems to develop distinct novel results involving the Hurwitz zeta function, Riemann zeta function, polylogarithms and Fibonacci numbers. In continuation, we obtain some zeros of the newly developed zeta functions and explain their behaviour using plots in complex plane. Furthermore, we provide particular cases for the theorems and corollaries that show that our results generalise the currently available functions and series such as the Riemann zeta function and the geometric series. Finally, we provide four miscellaneous examples to showcase the vast scope of the developed theorems and showcase that these two theorems can provide hundreds of new results and thus can potentially create an entirely new field under the realm of number theory and analysis

Forgotten effects and heavy moving averages in exchange rate forecasting

© 2019, Bucharest University of Economic Studies. All rights reserved. The paper presented different exchange rate forecasting models based on fundamental economics using different aggregation information operators such as heavy moving average, forgotten effects and expertons. The heavy ordered weighted moving average weighted average (HOWMAWA) operator is introduced. This new operator includes the weighted average in the typical heavy ordered weighted moving average (HOWMA) operator, considering a degree of importance for each concept that includes the operator. The use of expertons and forgotten effects methodology represents the information of experts in the field, with which hidden variables or second-degree relations were obtained. Once these items were detected, they were included in the econometric models, and the forecast of exchange rate of USD/MXN was performed using time series and HOWMA and HOWMAWA operators. The results show that the inclusion of the forgotten effects and heavy moving average operators improves our results and reduces the forecast error
