Extended multivariate comparison of 68 cluster validity indices. A review2024 •
Clustering is an unsupervised machine learning methodology widely used in several sciences to find groups of similar patterns in complex data. The results generated by clustering algorithms generally depend on userdefined input parameters such as the number of expected clusters, which can have a great impact on the homogeneity of the identified clusters. Clustering validity indices (CVIs) are an effective method for determining the optimal number of clusters that best fit the natural partition of a dataset. They do not require any underlying assumption nor a priori knowledge about the true dataset structure. Since 1965, many cluster validity indices have been proposed in the literature and used in several different applications. In this paper, the performance of 68 cluster validity indices was evaluated on 21 real-life research and simulated datasets. CVIs were compared on the same partition for each dataset, which was searched for by the kmeans clustering algorithm. Multivariate chemometric methods were applied to disclose mutual relationships among the indices and to select those that are more effective in terms of accuracy and reliability.

Acuerdos jurídicos y debate. El caso de los tribunales constitucionales2016 •
El trabajo es una colección de parágrafos que tratan de presentar al lector dos cuestiones íntimamente relacionadas entre sí. La primera cuestión es la de las conexiones que pueden trazarse entre la acción de “acordar” (tomar o alcanzar acuerdos) y la actividad de “debatir”. La segunda es la proyección de lo anterior sobre el debate que tiene lugar en el seno de un tribunal constitucional.
There have been two great developments in Catholic Social Teaching: the preferential option for the poor and the idea of social sin. The preferential option of the poor is the vital lens through which to see social ills as primarily affecting the poor, and what it sees are not only personal sins, but sins embedded in social structures that inevitably affect individuals, especially the poor.

Some inscriptions from southern Turkey / Neuf inscriptions2023 •
Bu makalede konu edilen dokuz adet eserin incelenmesi ve yayınlanması, ilgili Müze Müdürlüğü tarafından 20 Eylül 2018 tarih ve 77400317- 155.03-762463 sayı ile verilen yazılı bir izin sayesinde gerçekleşmiştir. This article will be displayed in Academia beginning from January 1, 2026, as it can be filed on freely accessible online archives no earlier than one year after the release of its journal. Please e-mail me for obtaining this brief article before 2026: elafli@yahoo.ca In this article, nine formerly unpublished Greek inscriptions from southern Turkey are presented in detail. Except one example, these finds are currently being displayed in an open-air museum in a castle which was built in the XIVth century by the Karamanid Turks and today serves as an offshot section of a museum. The first text is an honorific dedication to Teukris, daughter of Caper, and the eight other texts are carved on the sarcophagi of Marcus Aurelius Diogenes, Stephanos, Marcus Aurelius Neon, Aurelia Antonia, Aurelius Valentinianus, Sempronia Cyrilla, Gaius Iulius Capito and Flavius Diophantos. These nine texts can be dated between the end of the second century and the fourth century A.D. On the epigraphic and historical point of view, onomastics is the main interest of this paper, thanks to several new or rare names (Luwian-Anatolian and rare ancient Greek personal names). They are also evidence of social and civic life, especially by funerary pratices. KEYWORDS: Eastern Roman colonies, funerary texts, onomastics.
El estándar de gestión de la calidad desarrollado por la Unión Europea, ISO 9001, fue publicado hasta 1987 con una serie de desventajas con respecto a la filosofía japonesa KAIZEN. No fue sino hasta la publicación de la norma ISO 9001:2000 que se optimizaron sus requisitos al jerarquizar los Tres Pilares de KAIZEN: Mejora Continua de Procesos, Responsabilidad de la Dirección y Asegurar la Satisfacción del Cliente. De esta manera, el círculo virtuoso del aprendizaje colaborativo se ha completado.
