No effect of lack of wood for acorn ant colonies development
2021
Acorn ants mostly inhabit cavities in fallen twigs and hollow acorns. Such places, e.g., dead wood, provide an attractive living resource for many groups of microorganisms, like fungi and bacteria, which can be important for ants. However, during experiments in laboratories, acorn ant colonies are typically kept without dead wood. During laboratory experi-ments, the preferences of the ant Temnothorax crassispinus for nest sites with pieces of dead wood were checked, and whether the presence of such wood influenced productivity. In binary choice tests, colonies had to choose a nest site when presented with two potential nest sites, one empty, or two cavities with different contents. The ant …
IMPLICACIONES DEL USO DE BUSCADORES EN EL COMPORTAMIENTO DE COMPRA ONLINE / IMPLICATIONS OF THE SEARCH ENGINES USE IN THE ONLINE SHOPPING BEHAVIOUR
2009
El objetivo del presente trabajo es analizar los factores que influyen en el uso de buscadores y su incidencia en el comportamiento de compra en Internet. El análisis de resultados obtenidos a partir de una muestra representativa de 485 compradores por Internet españoles, pone de manifiesto que los consumidores que consideran la comodidad, reducciones de precio y amplitud de surtido como motivaciones relevantes para realizar compras online presentan una mayor predisposición al uso de buscadores en la realización de sus compras virtuales. La experiencia como internauta y como comprador en Internet son factores que influyen negativamente en el uso de buscadores para la realización de compras …
AGONISTIC INTERACTIONS IN A LIOLAEMUS LIZARD: STRUCTURE OF HEAD BOB DISPLAYS
2007
Males from different iguanian lizard species engage in frequent visual signaling during agonistic interactions, mainly by displaying head bobs. We conducted a detailed study of the structure of head bob displays mediating male agonistic interactions in Liolaemus lemniscatus lizards. We staged pair-wise encounters where one male, the intruder, was placed in the terrarium of a conspecific male, the resident. During these interactions, males exhibited only one type of head bob display made up of three distinct units: a low amplitude bob (unit 1), a brief pause (unit 2), and two consecutive high-amplitude bobs (unit 3). Head bob displays occurred singly or as a part of a bout, with a mean numbe…
Sport motivation among young adolescents in Finland, Norway and Sweden
2007
Within a health promotion perspective, nationwide surveys on health behaviour and lifestyle in 11- to 15-year-old schoolchildren were carried out in Finland, Norway and Sweden in 1985–1986. The surveys were part of an international World Health Organization study on health behaviour in school-age children. The findings suggest that social, fun and health motives are perceived as the main motivations for sport participation. Competition and achievements were not rated as important reasons for liking sport, with older pupils seeming to attach more importance to sport being fun. Winning and achieving better skills in sport seem to decrease in importance as pupils grow older. The present findin…
Comportamentos de suporte e eficácia grupal: o papel mediador dos comportamentos de aprendizagem
2018
Dissertação de Mestrado em Psicologia do Trabalho, das Organizações e dos Recursos Humanos apresentada à Faculdade de Psicologia e de Ciências da Educação Supportive behaviours, defined “as the extent to which team members voluntarily provide assistance to each other when needed during task accomplishment” (Aubé & Rousseau, 2005, p.193), constitute a determinant of Team Effectiveness (Dimas, Rocha, Rebelo, & Lourenço, 2016). The current research aims to clarify further the relationship between Supportive Behaviours and Team Effectiveness criteria, mediated by Team Learning Behaviours. Based on the model of effectiveness Input-Mediator-Outcome-Input (IMOI) from Kozlowski and Ilgen (2006), th…
Influencia del perfil sociodemográfico relaciones con el medio y actitud ante la compra a distancia en el comportamiento de compra por television
2007
El objetivo de la presente investigación es profundizar en el estudio de los factores determinantes del comportamiento de compra a través de la televisión. Con este fin, se plantean un conjunto de hipótesis sobre la influencia del perfil sociodemográfico, la exposición al medio televisivo y al género de compra televisiva y la actitud ante el sistema, en la decisión de compra por televisión. Del análisis de resultados obtenidos de una muestra de 200 telecompradores españoles, se pone de manifiesto que la exposición al género de compra por televisión y la actitud ante el sistema son predictores significativos del comportamiento de compra a través de la televisión. / This paper aims to present…
Identifying relevant segments of AI applications adopters : Expanding the UTAUT2’s variables
2021
Artificial intelligence (AI) is a future-defining technology, and AI applications are becoming mainstream in the developed world. Many consumers are adopting and using AI-based apps, devices, and services in their everyday lives. However, research examining consumer behavior in using AI apps is scant. We examine critical factors in AI app adoption by extending and validating a well-established unified theory of adoption and use of technology, UTAUT2. We also explore the possibility of unobserved heterogeneity in consumers’ behavior, including potentially relevant segments of AI app adopters. To augment the knowledge of end users’ engagement and relevant segments, we have added two new antec…
Constitutive Models for the Tensile Behaviour of TRM Materials: Literature Review and Experimental Verification
2021
In recent years, the scientific community has focused its interest on innovative inorganic matrix composite materials, namely TRM (Textile Reinforced Mortar). This class of materials satisfies the need of retrofitting existing masonry buildings, by keeping the compatibility with the substrate. Different recent studies were addressed to improve the knowledge on their mechanical behaviour and some theoretical models were proposed for predicting the tensile response of TRM strips. However, this task is complex due to the heterogeneity of the constituent materials and the stress transfer mechanism developed between matrix and fabric through the interface in the cracked stage. This paper present…
Shopping with virtual hands
2020
Retailers can use virtual reality as a new touchpoint for their customers: within an existent channel or as a new sales channel. Thus, it is crucial to understand the differences and similarities between the physical and the virtual shopping environment. Shopping simulations make it possible to test, observe, and collect data in a controlled, low-cost, and fast way compared to field experiments. However, past studies might have provided biased results due to the characteristics of the sample used. This study analyzes how consumers behave in two virtual shopping tasks. The exploratory, experimental research uses an immersive VR shopping environment and a sample of participants balanced acros…
A framework for modelling the biomechanical behaviour of the human liver during breathing in real time using machine learning
2017
Progress in biomechanical modelling of human soft tissue is the basis for the development of new clinical applications capable of improving the diagnosis and treatment of some diseases (e.g. cancer), as well as the surgical planning and guidance of some interventions. The finite element method (FEM) is one of the most popular techniques used to predict the deformation of the human soft tissue due to its high accuracy. However, FEM has an associated high computational cost, which makes it difficult its integration in real-time computer-aided surgery systems. An alternative for simulating the mechanical behaviour of human organs in real time comes from the use of machine learning (ML) techniq…
