Behavior adaptation and selection.

2010

6 pages; The evolutionary approach to behavior is concerned with the evolutionary origin and adaptive function of behavioral traits. Like any other part of the phenotype, behavior can be shaped by natural selection to produce adaptations. However, behavior often shows large phenotypic variation and flexibility, and can be both – subject to selection and a major agent of selection. Therefore, the study of adaptation and evolution of behavior is a particularly complex one, involving a wide range of methodologies and techniques, including mathematical modeling, comparative methods, phenotypic engineering, quantitative genetics, genetic dissection, and artificial selection.

TESTING SIMILARITY COEFFICIENTS FOR ANALYSIS OF THE FOSSIL RECORD USING CLUSTERING METHODS: THE PALAEOZOIC FLORA AS A STUDY CASE

2020

This paper reports a global methodological approach based on the similarity and clustering methods of the Palaeozoic plant fossil record using a comparative approach between two similarity measures: the Jacard and Raup-Crick Coefficients. The results show that although the Raup-Crick Coefficients clearly have the potential for providing more robust results, the consequences of the extinction processes are better reflected in the similarity analysis based on the Jaccard Coefficients. On the other hand, the cluster analysis based on UPGMA algorithm shows four robust clusters and reveals new evidence for the singularity of Mississippian flora. Finally, the results obtained reveal that similari…

Sports participation in France and Spain: An international comparison of voraciousness for sport

2020

International audience; The societal comparative approach used in this article to assess voraciousness for sport is based on local surveys. The global was studied at a local level, based on a lengthy process of harmonization of quantitative local surveys. The research is carried out in two countries that are geographically close, but quite different to each other: France and Spain. In an increasingly globalized world, the objective is to examine differences in the social uses of physical activities and sports (PAS) between the two populations, by explaining them with respect to the differences between these two societies as a whole. The social differentiations identified in the portfolio si…

Ocnos : revista de estudios sobre lectura

2009

Resumen basado en el de la publicación Título, resumen, palabras clave en español e ingles Se plantea el siguiente interrogante, ¿cuáles deben ser, en la sociedad del s. XXI , los objetivos de la educación literaria? El camino de la renovación debe venir por la recuperación de su valor instructivo. La capacidad cognoscitiva para interpretar la realidad y la construcción sociocultural parece uno de los ejes. No obstante, cabe subrayar el placer que provoca la lectura como base para la adquisición de la competencia literaria. Asimismo, otro aspecto fundamental es el corpus de textos que deben utilizarse. Este debe ser, en todos los sentidos, multicultural, esto es, textos clásicos, universale…

Sexual conflict drives micro- and macroevolution of sexual dimorphism in immunity

2021

Abstract Background Sexual dimorphism in immunity is believed to reflect sex differences in reproductive strategies and trade-offs between competing life history demands. Sexual selection can have major effects on mating rates and sex-specific costs of mating and may thereby influence sex differences in immunity as well as associated host–pathogen dynamics. Yet, experimental evidence linking the mating system to evolved sexual dimorphism in immunity are scarce and the direct effects of mating rate on immunity are not well established. Here, we use transcriptomic analyses, experimental evolution and phylogenetic comparative methods to study the association between the mating system and sexua…

Firm survival: The role of incubators and business characteristics

2015

This paper analyzes the impact of business incubators on firm survival. Using a configurational comparative method, namely fuzzy-set qualitative comparative analysis (fsQCA), the article also examines whether degree of business innovation, size, sector, and export activity affects firm survival. Results show that, when combined with other variables (i.e. sector, technology), business size is a sufficient condition for firm survival. Likewise, incubators alone cannot affect survival. A combination between incubators and other factors is necessary to ensure firm survival. Sin financiación 2.129 JCR (2015) Q2, 40/120 Business UEV

Research trends in retailing: a comparative approach Spain-Europe-USA

2002

This paper describes the evolution of research in retailing comparing three different geographic regions: Spain, Europe and the United States. Working on the basis of a bibliographic review of the academic research published between 1996 and 2000 together with a content analysis, the results of this study reveal a heterogeneous evolution in nine thematic areas related to the field of retailing. The differences are particularly noticeable when comparing those of Europe with those of the USA, and reveal different areas of interest over the last five years.

COMPARING THE MARSHALL PLAN AND THE EUROPEAN NEXT GENERATION UE. Models and Legal Tools of International and Supernational Cooperation to Promote Eco…

2022

The article analyzes and compares the European Recovery Plan of 1948, commonly known as the Marshall Plan, for the reconstruction of Europe after the Second World War (paragraphs 2, 2.1, 2.2), and the Next Generation EU (paragraphs 3, 3.1) through the lens and methods of legal comparison and historical analysis. As the description of the law cannot ignore the historicization of the object of study, such comparison is carried out inductively, through the analysis of the legal mechanisms in their concrete attitudes and the construction of descriptive schemes of facts, having regard to the legal discipline, but also to the functional profiles and the context in which the rules are conceived. T…

Tradizioni carnevalesche a Mezzojuso: dal Mastro di Campo al rogo del Nannu

2023

Il Mastro di Campo di Mezzojuso è una performance carnevalesca tradizionale che presenta un articolato simbolismo rituale riconducibile al pattern delle cerimonie di capodanno. In particolare si osservano il tema della ierogamia e della lotta rituale come elementi di promozione della fecondità. Ambedue i simboli rituali, la rappresentazione di una danza o di uno scontro armato, con l'eventuale coinvolgimento degli astanti e la celebrazione di un matrimonio, correlati o disgiunti, sono, come è noto, costitutivi ab antico delle cerimonie di capodanno, segnatamente di quelle primaverili. Altri rituali carnevaleschi europei hanno una simile articolazione. Il saggio presenta una serie di esempi …
