The DDG^G-classifier in the functional setting

The Maximum Depth was the first attempt to use data depths instead of multivariate raw data to construct a classification rule. Recently, the DD-classifier has solved several serious limitations of the Maximum Depth classifier but some issues still remain. This paper is devoted to extending the DD-classifier in the following ways: first, to surpass the limitation of the DD-classifier when more than two groups are involved. Second to apply regular classification methods (like $k$NN, linear or quadratic classifiers, recursive partitioning,...) to DD-plots to obtain useful insights through the diagnostics of these methods. And third, to integrate different sources of information (data depths or multivariate functional data) in a unified way in the classification procedure. Besides, as the DD-classifier trick is especially useful in the functional framework, an enhanced revision of several functional data depths is done in the paper. A simulation study and applications to some classical real datasets are also provided showing the power of the new proposal.Comment: 29 pages, 6 figures, 6 tables, Supplemental R Code and Dat

Autoproblem : motor generador de problemes d'estadistica bàsica

Els objectius del projecte són: -Crear un conjunt d'aplicacions portables a qualsevol ordinador, per tal de que arribi al màxim d'usuaris possibles sigui quina sigui la seva situació geografica, si és a casa o si és a la facultat. D'aquesta manera es vol crear una aplicació que es pogués utilitiar com a material de classes de pràctiques, o com a material d'examen, o simplement perque l'estudiant pugui estudiar l'assignatura. - Creació d'un conjunt de rutines de simulació de dades aleatóries. D'aquesta manera estudiants que executen el mateix problema alhora tenen dades diferents, i per tant poden arribar a conclusions diferents. - La creació d'un programa d'edició de problemes senzill i fàcíl d'utilitzar per part del professor. - Crear una aplicació de resolució seqüencial i guiada deis problemes plantejats pel professor. Aquest és un dels objectius més importants, doncs es vol que l'estudiant resolgui el problema plantejat per l'aplicació de manera que posi en pràctica tot el que ha après a la classe i a més, que el resolgui d'una manera seqüencial. La creació d'un sistema de control deis estudiants que executin els problemes a la pàgina web. Aquest objectiu assolir aquest objectiu és important de cara a fer pràctiques o exàmens amb l'aplicació de l'estudiant. D'aquesta manera el professor pot conèixer l'evolució deIs seus estudiants al llarg del quadrimestres en que es faci l'assígnatura

Programación didáctica de la materia Empresa y Diseño de Modelos de Negocio bajo el enfoque del DUA

La atención a la diversidad en la actualidad se incorpora de manera integral a la intervención educativa, como derecho fundamental que tienen todos los alumnos a obtener una educación de calidad. La diversidad en el alumnado se manifiesta en multitud de elementos, entre otros, la etnia, la raza, la religión, la procedencia, la condición social, el género, la lengua y las necesidades educativas especiales. Todos ellos influyen en la forma de aprender del estudiante. Hasta ahora, el currículo se desarrollaba (objetivos, materiales, medios, procesos, metodología, actividades, tareas) para la totalidad de los alumnos, provocando que una minoría quedara excluida por el simple hecho de no tener acceso al proceso de aprendizaje. Para dar respuesta a la construcción de una educación verdaderamente inclusiva surge el “Diseño Universal de Aprendizaje” (DUA) (CAST, 2018), convirtiendo las aulas en lugares donde todos los alumnos pueden alcanzar su máximo potencial educativo y personal. Este trabajo plantea el desarrollo de una propuesta didáctica, teniendo como pilar fundamental de su elaboración el DUA.Máster en Profesor de Educación Secundaria Obligatoria y Bachillerato, Formación Profesional y Enseñanzas de Idioma

The impact of ownership structure on corporate reputation: evidence from Spain

Research Question/Issue: This study examines the influence of firms' ownership structure on corporate reputation. Research Findings/ Insights: Using archival data from a panel of firms in Spain for 2000–2007, we found that ownership concentration in the hands of the largest shareholder erodes corporate reputation, whereas contestability of the main shareholder's power enhances it. Insider ownership shows a non-linear relationship with corporate reputation, with lower corporate reputation at low and very high levels of insider ownership. Finally, if the largest shareholder is either a pressure-resistant or a pressure-sensitive institutional investor, as opposed to other types of largest shareholder, corporate reputation is lower. This last finding markedly differentiates our sample of firms in Spain, a civil law country, from firms in common law countries such as the USA and the UK, where studies have found a positive relationship between institutional investors and corporate reputation. Theoretical/Academic Implications: Drawing on signaling and agency theories, our paper is, to the best of our knowledge, the first to analyze the influence of ownership structure on corporate reputation in civil law countries. Practitioners/Policy Implications: This study suggests that managers and directors should recognize how each characteristic of ownership structure influences the expectations of stakeholders. Low levels of ownership concentration in the hands of the largest shareholders, low differences in ownership concentration between first and second largest shareholders, and moderate levels of insider ownership are positive signals that should be communicated to foster corporate reputation. High levels of ownership concentration in the hands of the largest shareholders or high differences in ownership concentration between first and second largest shareholders impair corporate reputation and should be compensated by introducing corporate governance mechanisms that favor corporate reputation, such as increasing the number of independent directors or avoiding CEO duality

Election of Water Resources Management Entity Using a Multi-Criteria Decision (MCD) Method in Salta Province (Argentine)

At present, the water resources are a strategic element each time more necessary and limited becoming a source of conflicts. For that, it is fundamental to create an independent and competent entity with good reputation and social acceptation. This entity must be able to obtain, store and process all data dispersed in different entities creating a network for these purposes. Finally, it must be able to organize different branches between the government and the final users. Using one of the wellknown Multicriteria Decision Methods(MCDM) with several realistic alternatives and several criteria identified in expert seminars in Salta and Madrid, we have obtained hopeful results and more recently new modifications introduced have generated better results

Medicinal plants for rich people vs. medicinal plants for poor people: a case study from the Peruvian Andes

Traditional knowledge (TK) of medicinal plants in cities has been poorly studied across different inhabitants’ socioeconomic sectors. We studied the small city of Chachapoyas (~34,000 inhabitants) in the northern Peruvian Andes. We divided the city into three areas according to the socio-economic characteristics of its inhabitants: city center (high), intermediate area (medium), and city periphery (low). We gathered information with 450 participants through semi-structured interviews. Participants of the city periphery showed a higher TK of medicinal plants than participants of the intermediate area, and the latter showed a higher TK than participants of the city center. The acquisition of medicinal plants was mainly through their purchase in markets across the three areas, although it was particularly relevant in the city center (94%). Participants of all socioeconomic levels widely used the same medicinal plants for similar purposes in Chachapoyas, which is likely based on a common Andean culture that unites their TK. However, participants with the lowest socioeconomic level knew and used more plants for different medicinal uses, indicating the necessity of these plants for their livelihoods. City markets with specialized stores that commercialize medicinal plants are key to preserve the good health of poor and rich people living in Andean cities and societie
