Prioritization of Alternatives with AHP Plus Response Latency and Web Surveys
2013
Purpose: Overcome some drawbacks of the widely applied Analytical Hierarchy Process (AHP) related to the use of a rating scale for respondent’s judgments and propose a new method to prioritize alternatives based on web surveys. Methodology/Approach: We use the response latency, i.e. the time taken to make a decision, to replace the rating scale in the pairwise comparisons which is a fundamental part of the AHP procedure. A method combining the AHP with a mathematical model for the response latency is proposed in the paper. Findings: Eliminating the rating scale and leaving only the “take the best” task alleviates the respondent and makes the survey much faster and intuitive. Moreover the re…
ESTIMATION OF ATTRIBUTE IMPORTANCE BY CHOICE TIME IN A RANKING TASK
2010
The evaluation of the quality of products and services as a function of their attributes has been broadly implemented in marketing research. The current methods for identifying important attributes and prioritize them suffer from theoretical and practical limitations. The former are related to the choice of the most appropriate model for the specific experimental context, the latter are due to the large amount of variables (cognitive, context and survey variables) affecting the chosen model. This work aims at presenting a new method for capturing consumer attribute preferences and estimating the relative importance weights by using the choice time in a ranking task. All is made through an e…
The roles of job and worker restructuring in aggregate wage growth dynamics
2019
We propose an approach for measuring and analyzing the dynamics of the standard aggregate wage growth of macro statistics with micro data. Our method decomposes the aggregate wage growth into the wage growth of job stayers and into various terms related to job and worker restructuring. This method produces explicit expressions with clear interpretations for the various restructuring components. Using comprehensive longitudinal employer–employee data, we study how job and worker restructuring influence the aggregate wage growth and its cyclicality. The results highlight the importance of drawing a sharp distinction between job and worker restructuring in the analysis of aggregate wage growth…
On the use of multi-temporal series of COSMO-SkyMed data for LANDcover classification and surface parameter retrieval over agricultural sites
2011
The objective of this paper is to report on the activities carried out during the first year of the Italian project “Use of COSMO-SkyMed data for LANDcover classification and surface parameters retrieval over agricultural sites” (COSMOLAND), funded by the Italian Space Agency. The project intends to contribute to the COSMO-SkyMed mission objectives in the agriculture and hydrology application domains.

Validez factorial de la adaptación al español del Maslach Burnout Inventory-General Survey The Factorial Validity of the Maslach Burnout Inventory-Ge…
2002
Objetivo. Explorar la estructura factorial de una adaptación al castellano del "Maslach Burnout Inventory-General Survey" (MBI-GS). Material y métodos. La muestra la integraron 149 policías municipales de Tenerife, España, a quienes se les aplicó el cuestionario en 1999. Se realizó un análisis factorial mediante Componentes Principales y rotación Varimax. Resultados. Cuatro factores tuvieron eigenvalues mayores que 1. En el Factor I se agruparon los items de Eficacia Profesional, en el Factor II tres items de Cinismo, en el Factor III los items de Agotamiento, y en el Factor IV dos items de Cinismo. Posteriormente se realizó otro análisis ajustando a tres la extracción de factores. La soluc…
Sampling in Local Tourism Quantification: Critical Issues and Field Experience
2013
The aim of this paper is to detail some issues relating to tourist sampling by means of three case studies. Tourism quantification issues and solutions will be illustrated in three paradgmatic situations: sampling in a self-contained context with multiple access points (an Island in Aeolian archipelago), tourism in a seaside town, and nautical tourism. In these contexts the issue of building a space-time grid to circumscribe the target population is made more complex by the mobile nature of these populations.
