Unha Perspectiva Combinada Para Acceder a Cambios a Curto Prazo Na Situación Económica De Portugal E España

Abstract

Este artigo propón un método diferente para identificar a curto prazo cambios naactividade económica. Usamos unha perspectiva baseada nas opinións de varios recoñecidoseconomistas españois e portugueses sobre a importancia dun grupo de indicadoresindividuais aceptados de forma xeral, que poidan avaliar a situación económica. O obxectivodo artigo é o de determinar a posición económica relativa nun período de tempo a curto emedio prazo e analizar a importancia da opinión dos economistas para describir a situacióneconómica. Recolléronse datos trismestrais do período de 1995 a 2014 (1º semestre) dasestadísticas da OECD.StatExtracts para Portugal e España. Os resultados apoian a idea de queas opinións dos economistas son importantes para explicar as características dunhaeconomía. Malia que as súas opinións sobre o peso dunha variable determinada nadescrición do nivel de actividade económica pode variar, implicitamente a longo prazo todaslas opinións tenden a converxer nun mesmo patrón de evolución dunha situación económica.

Creation and Validation of the European Portuguese Version of the Systemic Lupus Erythematous Quality of Life Questionnaire

“…The KMO score was good (0.885) and Bartlett's test of sphericity was associated with a p < 0.001. Similarly to the authors of the original version [1], we found the following six factors explained the 40 items of the SLEQoL: (F1) physical functioning (items 1-6) and physical symptoms (items 21-23); (F2) mood and self-image (items [16][17][18][19] and low self-esteem (item 34); (F3) social and occupational activities (items 7-13 and 28-31) and the embarrassment question (item 35); (F4) unpredictability of the response to treatment (items 36-39), including exposure to the sun (item 14) and making less money (item 15); (F5) self-esteem (items 32-35); and (F6) unpleasant aspects of the treatment (items 24-27). The variance explained by these six factors was 65% (H2).…”

“…For structural validity, we performed factor analysis based on principal components estimates after testing the sampling adequacy through the Kaiser-Meyer-Olkin (KMO) test and Bartlett's test of sphericity. A KMO score lower than 0.60 was considered poor, between 0.60 and 0.70 was considered fair, between 0.70 and 0.80 was considered average, between 0.80 and 0.90 was considered good, and higher than 0.90 was considered very good [18]. Bartlett's sphericity test should have an associated significance lower than 0.001.…”

“…A KMO smaller than 0.50 or between 0.50 and 0.60 is considered unacceptable or poor, and if between 0.60 and 0.70, between 0.70 and 0.80, between 0.80 and 0.90, or higher than 0.90, is seen, respectively, as fair, average, good, or very good. The significance of the Bartlett sphericity test should be smaller than 0.001 [ 33 ].…”
