No full textNotes on the Latin American Conceptual Construction of Urban Fragmentation. A Focus on the Tourism Vector
No full textLos espacios metropolitanos reflejan procesos de incremento de desigualdades sociales, siendo las actividades turísticas unas de las que generan dichas transformaciones urbanas. Este artículo busca recorrer la producción científica en la cuestión de la fragmentación urbana, con el objetivo doble de reflexionar sobre la construcción teórica de este concepto desde América Latina y la posible aplicación de este dispositivo teórico en otras áreas urbanas y metropolitanas transformadas por actividades turísticas intensivas. A partir de la construcción de un corpus de publicaciones de referencia sobre metrópolis latinoamericanas, se aplica un enfoque de análisis discursivo hermenéutico, que se combina con una aproximación comparativa. Primero, se constata la presencia de estudios empíricos y, en menor medida, teóricos sobre “fragmentación urbana”, en espacios urbanos y metropolitanos marcados históricamente por fracturas sociales especialmente importantes. Segundo, la emergencia de transformaciones vinculadas a actividades turísticas, en diferentes casos de estudio, muestra formas de fragmentación urbana y permite enfoques innovadores para su estudio. Finalmente, se discute la manera en la que este dispositivo teórico de la fragmentación urbana, entendido de una manera holística al considerar la trialéctica social, urbana y política, contribuye al análisis de procesos de transformación urbanas atravesadas por fenómenos turísticos recientes.Metropolitan areas reflect processes of increasing social inequalities, with tourism activities being among those that generate such urban transformations. This article aims to traverse the scientific production on the issue of urban fragmentation, with the dual objective of both reflecting on the theoretical construction of this concept from Latin America and the possible application of this theoretical framework in other urban and metropolitan areas transformed by intensive tourism activities. Drawing from a corpus of reference publications on Latin American metropolises, a discursive and hermeneutic analysis is applied in combination with a comparative approach. First, the emergence of empirical studies and, to a lesser extent, theoretical studies on urban fragmentation is highlighted in urban and metropolitan areas which have been historically marked by particularly significant social fractures. Second, the emergence of transformations linked to tourism activities, in different case studies, reveals forms of urban fragmentation and enables innovative approaches to its study. Finally, the discussion revolves around how this theoretical apparatus of urban fragmentation could be both understood in a holistic manner by considering the social, urban, and political trialectics, and applied to the analysis of urban transformation processes which are influenced by recent tourism phenomena.2
Blanca Catalán de Ocón’s notebook: memoir of a naturalist who connected botany, arts and poetry
No full textLa botánica Blanca Catalán de Ocón y Gayolá (1860-1904) vivió su juventud rodeada de la belleza
de la naturaleza, el saber científico y el gusto la poesía que se respiraba en cada rincón de su hogar;
un inmenso valle en el corazón de la Sierra de Albarracín. Elaboró un detallado herbario con más de
ochenta especies, algunas desconocidas para la ciencia. Sin embargo, la naturaleza fue para ella mucho
más que un elemento a analizar científicamente. Se convirtió en fuente de inspiración, manifestada
en poemas y composiciones florales. En este trabajo examinamos su herbario y archivo personal,
reflexionando sobre las prácticas que vincularon las artes y la botánica como estrategia para crear
espacios alternativos de discusión científica.The botanist Blanca Catalán de Ocón y Gayolá (1860-1904) lived her youth surrounded by the beauty
of nature, scientific knowledge and the good taste for arts and poetry that in every corner of her home
situated in an immense valley in the heart of the Sierra de Albarracín. She composed an herbarium with
more than eighty species, some of them still unknown to science. However, Nature was much more
than an element to be scientifically analysed and became a source of artistic inspiration, manifested
in poems and floral designs. In this paper, we explore her herbarium and her private archive, and
we reflect on the practices that linked art with botany as a strategy to create alternative spaces for
scientific discussion.2952752
Ensemble methods for bankruptcy resolution prediction: a new approach
No full textWhen a company goes bankrupt, it generates an extremely important uncertainty for all stakeholders as to whether the company will be reorganized or liquidated. This study aims to provide a successful methodology to predict whether a bankrupt SME will reorganize or liquidate. This could prevent significant economic and social losses and would contribute to reduce the number of SMEs that are helped to reorganize when they have little chance of success or that are liquidated when they could be viable. This useful and valid methodology applies algorithms (e.g., k-nearest neighbors) and techniques of ensemble learning and performance evaluation algorithms for the first time, considering the reviewed literature. By applying this methodology, it is possible to achieve a performance far superior to that known in the literature, specifically with an average accuracy of 94 percent using a data set with only financial variables of 1683 Spanish SMEs in the period 2011–2019360,4981,9Q2Q2SCIESSCI11,
Prediction of tourism zombie companies using artificial intelligence algorithms and accounting data
No full textThis paper addresses the problem of the prediction of zombie companies. Despite their relevance, financial issues represent an area scarcely considered in relation to the tourism industry and this topic has so far remained totally unexplored. Zombie firms cause great damage to the sector in which they compete. However, there is no consensus regarding what actions should be applied to them are not due to the negative consequences of maintaining or liquidating them. In view of this, the key issue is to prevent them from entering this state. It would therefore be useful to have a methodology for predicting years in advance when a company will become a zombie firm. For this purpose, this article has used different artificial intelligence algorithms applied to easily obtained accountant data. Thus, 78.4% of correct predictions have been utilizing a dataset of 356 Spanish small and medium-sized enterprises in the tourism sector.220,614Q2ESCI9,6ERIH PLU
