The Three Steps of Clustering in the Post-Genomic Era: A Synopsis
2011
Clustering is one of the most well known activities in scientific investigation and the object of research in many disciplines, ranging from Statistics to Computer Science. Following Handl et al., it can be summarized as a three step process: (a) choice of a distance function; (b) choice of a clustering algorithm; (c) choice of a validation method. Although such a purist approach to clustering is hardly seen in many areas of science, genomic data require that level of attention, if inferences made from cluster analysis have to be of some relevance to biomedical research. Unfortunately, the high dimensionality of the data and their noisy nature makes cluster analysis of genomic data particul…

Artificial intelligence in the diagnosis of pediatric allergic diseases.
2020
Abstract: Artificial intelligence (AI) is a field of data science pertaining to advanced computing machines capable of learning from data and interacting with the human world. Early diagnosis and diagnostics, self-care, prevention and wellness, clinical decision support, care delivery, and chronic care management have been identified within the healthcare areas that could benefit from introducing AI. In pediatric allergy research, the recent developments in AI approach provided new perspectives for characterizing the heterogeneity of allergic diseases among patients. Moreover, the increasing use of electronic health records and personal healthcare records highlighted the relevance of AI in …
Too close for comfort? The impact of salesperson‐customer proximity on consumers' purchase behavior
2021
Across a series of lab and field studies, with a total sample of over 1200 participants, we investigate how the physical proximity between salespeople and customers can impact store loyalty, purchase intentions, and actual spending. An initial survey among a representative sample of retail salespeople reveals that they associate close physical proximity between employees and customers with positive consumer outcomes, an intuition that dovetails with prior research documenting the positive influence of such proximity on purchase intentions, particularly in nonexpressive consumption contexts. Contrary to this work, we demonstrate, across four studies in which proximity was both measured and m…
Los beneficios del mar: negocios e inversiones económicas de la oficialidad naval en el siglo XVIII
2019
Throughout the eighteenth century, the Spanish navy was extensively reformed and enhanced as a consequence of the new model of Monarchy that the Bourbons introduced. Among the measures adopted, it is remarkable the erection of the naval officers corps according to the needs and obligations that maritime war had in this century. This group becomes the paradigm of the new professionalization and new training approach, and its members had great relevance due to its great mobility around the empire and the power of the naval institution. This means that a part of the naval officers were placed in privileged positions and at the intersection of diverse political, social and economic networks. Th…
What hampers green product innovation: the effect of experience
2019
Based on representative firm-level survey data for Austria, Germany, and Switzerland, this study systematically analyzes the relevance and drivers of barriers to green product innovation using the example of green energy technologies. “Low willingness to pay”, “high development costs”, “high commercial uncertainty”, and “lack of favorable political framework” are identified as the most important barriers. Moreover, we find that the firms’ innovation experience is an important driver of the level of green innovation barriers. Green innovation barriers are more accentuated for firms with green innovation activity than for firms with no green innovation activity. However, experience from diffe…
Fiabilidad y evidencias de validez de un instrumento para la evaluación de la calidad de los mapas conceptuales
2017
Diversos autores han señalado el interés y la pertinencia de los mapas conceptuales como herramientas para el aprendizaje significativo. Sin embargo, la revisión de la literatura pone de manifiesto la escasez de propuestas dirigidas a la evaluación de los mapas con criterios objetivables y la complejidad de las existentes. El objetivo del presente estudio fue desarrollar un instrumento para la evaluación de los mapas conceptuales en formato rúbrica. De esta manera, se consigue que los alumnos posean una herramienta que permita, mediante indicadores precisos, la evaluación de la calidad tanto de sus ejecuciones como de las ejecuciones realizadas por otros. Se construyó una rúbrica que incluy…
Educación XX1 : revista de la Facultad de Educación
2019
Aprender a aprender es una de las competencias claves fijadas por la Comisión Europea (CE, 2005 y 2006) para los sistemas educativos de los países miembros. Las últimas investigaciones ponen de relieve la importancia de que los estudiantes universitarios aprendan a aprender, por lo que este estudio se ubica en la universidad. El objetivo es concretar un modelo teórico sobre dicha competencia que permita su operacionalización en los grados universitarios. Para ello se ha realizado una revisión de la literatura sobre el tema. Después de estudiar su fundamentación científica y la normativa reguladora, se analizaron múltiples modelos -especialmente provenientes de la literatura europea- y se pr…
Serendipity in recommender systems
2018
The number of goods and services (such as accommodation or music streaming) offered by e-commerce websites does not allow users to examine all the available options in a reasonable amount of time. Recommender systems are auxiliary systems designed to help users find interesting goods or services (items) on a website when the number of available items is overwhelming. Traditionally, recommender systems have been optimized for accuracy, which indicates how often a user consumed the items recommended by system. To increase accuracy, recommender systems often suggest items that are popular and suitably similar to items these users have consumed in the past. As a result, users often lose interest…
Differentiating among pragmatic uses of words through timed sensicality judgments
2013
Pragmatic and cognitive accounts of figurative language posit a difference between metaphor and metonymy in terms of underlying conceptual operations. Recently, other pragmatic uses of words have been accounted for in the Relevance Theory framework, such as approximation, described in terms of conceptual adjustment that varies in degree and direction with respect to the case of metaphor. Despite the theoretical distinctions, there is very poor experimental evidence addressing the metaphor/metonymy distinction, and none concerning approximation. Here we used meticulously built materials to investigate the interpretation mechanisms of these three phenomena through timed sensicality judgments.…
