In this paper we analyze education in European countries, both overall and from a gender perspective, and we use the information derived from this analysis to compare the educational situation of these countries with the one that we observe in several indicators which reflect other socioeconomic aspects thereof. For multidimensional analysis of the state of education taking into account gender, we use the Multiple Factor Analysis exploratory technique in order to analyze globally the relative positions of these countries as far as education is concerned. In addition, the educational situation of these countries, summarized by the first factors of the previous analysis, has been combined with the information provided to us by several socioeconomic indicators with the ultimate goal of detecting whether the behaviour of these countries as far as education is concerned is accompanied by some pattern in the rest of the analyzed indicators.

ObjectiveWe aimed to describe eating patterns among home-dwelling older subjects to establish typologies of eaters at higher or lower risk of malnutrition.DesignCross-sectional study between June and September 2015 using a standardised questionnaire. The questionnaire was given to home-help employees (responsible for delivering meals to home-dwelling older persons and helping them to eat). The employees were asked to complete the questionnaire three times during the same week, for the same older adults, in order to identify the totality of their food intake.SettingRegistered customers of the home meal delivery company ‘Azaé’ (France).Participants605 older home-dwelling persons were randomly selected among customers served by the home meal delivery company.OutcomesMultiple factor analysis was used to understand the different modes of food consumption and to establish eating profiles. Hierarchical classification was performed to construct eating profiles corresponding to the dietary habits of the respondents.ResultsAverage age of the older adults was 85.3 years; 73.5% were women. Overall, 59% of participants reported that they ate out of habit, while 33.7% said they ate for pleasure. We identified four different groups of eaters, at varying levels of risk for malnutrition. Individuals in group 4 had the highest food intake in terms of quantity; and were less dependent than individuals in group 1 (p=0.05); group 1 was at highest risk of malnutrition.ConclusionImproved understanding of eating habits can help detect risky behaviours and help caregivers to promote better nutrition among home-dwelling older subjects.

<p>Unit-weight sum scores (UWSSs) are routinely used as estimates of factor scores on the basis of solutions obtained with the non-linear exploratory factor analysis (EFA) model for ordered-categorical responses. Theoretically, this practice results in a loss of information and accuracy, and is expected to lead to biased estimates. However, the practical relevance of these limitations is far from clear. In this article we adopt an empirical view, and propose indices and procedures (some of them new) for assessing the appropriateness of UWSSs in non-linear EFA applications. A new automated approach for obtaining UWSSs that maximize fidelity and correlational accuracy is proposed. The appropriateness of UWSSs under different conditions and the behavior of the present proposal in comparison with other more common approaches are assessed with a simulation study. A tutorial for interested practitioners is presented using an illustrative example based on a well-known personality questionnaire. All the procedures proposed in the article have been implemented in a well-known noncommercial EFA program. </p>

La recodificación de variables es una etapa habitual en el análisis de datos de encuesta. No está exenta de riesgos, como pueden ser la introducción de sesgos o las posibles deformaciones de los datos originales. En este trabajo se propone una metodología de validación de cualquier recodificación, tanto de variables de escala métrica, como de escala categórica para reducir el número de categorías. El objetivo de la metodología propuesta es comprobar la adecuación de la recodificación, indicando en qué medida los datos recodificados mantienen la misma estructura de los datos originales. La metodología se basa en el uso de un método factorial, Multiple Factor Analysis (MFA), aplicado sobre una tabla global obtenida como yuxtaposición de los datos medidos con la escala original y los mismos datos medidos con la escala recodificada. El procedimiento ha sido testado a partir de un conjunto de datos reales extraídos de una encuesta de opinión pública sobre los principales políticos del Parlamento Español.

This work applies the Multiple Factor Analysis (MFA) as an exploratory methodology to analize the indicators of the education´s management that belong to 32 Colombian public Higher Education Institutions (HEIs) along the year 2013. The product of this work indicates that the majority of HEIs have similar structures, being different and better scored the following: La Universidad Nacional (UNAL), Antioquia (UDEA), Nacional Abierta y a Distancia (UNAD), Pamplona y del Valle. Also the UDEA has a high development in extension, formation, capacity and research which is considered one of the best HEIS in the country. The university of Valle has a high degree of welfare, formation and extension, besides moderate capacities on research in comparission with the UDEA wich is superior to the rest of the HEIs. Pamplona has too a high level of formation, extension and moderate weflare, research and capacity in relation to the UNAD. It worth to mention that UNAL is the best located on extension. However, it is surpassed by other University (UDEA) because has a better development in some variables associated to research and extension. To finish, there are other HEIs with too many weaknesses on the indicators of the education´s management wich are UFPS Ocaña, Sucre and Pacifico. These universities show certain problems of research, extension and capacity, but fundamentally strong shortcomings in formation and welfare.
