El Fotomuntatge arquitectònic. El cas de Mies Van der Rohe

El treball realitzat vol ser un anàlisi exhaustiu de l'efecte causat per l'aparició de la fotografia en la representació de l'arquitectura, la seva introducció en les presentacions dels projectes i l'ús del fotomuntatge. Amb el canvi de segle, del dinou al vint, la fotografia ja va començar a entrar en les diferents disciplines artístiques inclosa l'arquitectura, de tal manera que amb l'aparició de les avantguardes artístiques els moviments arquitectònics moderns també es van mostrar reaccionaris i van incloure, a part de nous conceptes arquitectònics, noves maneres de presentar-les, la qual cosa els va acostar a les propostes pictòriques i conseqüentment a la introducció de la fotografia en el seu procés de treball i de presentació.

Regression analysis of compositional data when both the dependent variable and independent variable are components

It is well known that regression analyses involving compositional data need special attention because the data are not of full rank. For a regression analysis where both the dependent and independent variable are components we propose a transformation of the components emphasizing their role as dependent and independent variables. A simple linear regression can be performed on the transformed components. The regression line can be depicted in a ternary diagram facilitating the interpretation of the analysis in terms of components. An exemple with time-budgets illustrates the method and the graphical features

Scoring Methods for Ordinal Multidimensional Forced-Choice Items

In most psychological tests and questionnaires, a test score is obtained by taking the sum of the item scores. In virtually all cases where the test or questionnaire contains multidimensional forced-choice items, this traditional scoring method is also applied. We argue that the summation of scores obtained with multidimensional forced-choice items produces uninterpretable test scores. Therefore, we propose three alternative scoring methods: a weak and a strict rank preserving scoring method, which both allow an ordinal interpretation of test scores; and a ratio preserving scoring method, which allows a proportional interpretation of test scores. Each proposed scoring method yields an index for each respondent indicating the degree to which the response pattern is inconsistent. Analysis of real data showed that with respect to rank preservation, the weak and strict rank preserving method resulted in lower inconsistency indices than the traditional scoring method; with respect to ratio preservation, the ratio preserving scoring method resulted in lower inconsistency indices than the traditional scoring method
