A habit is a regularity in automatic responding to a specific situation. Classical learning psychology explains the emergence of habits by an extended learning history during which the response becomes associated to the situation (learning of stimulus-response associations) as a function of practice ("law of exercise") and/or reinforcement ("law of effect"). In this paper, we propose the "law of recency" as another route to habit acquisition that draws on episodic memory models of automatic response regulation. According to this account, habitual responding results from (a) storing stimulus-response episodes in memory, and (b) retrieving these episodes when encountering the stimulus again. …

Jóvenes transitando a la educación posobligatoria: el reflejo de la injusticia hermenéutica en sus discursos

2020

Los factores que influyen en las elecciones de los jóvenes a la hora de transitar de la etapa educativa obligatoria a la posobligatoria han sido ampliamente estudiados. La confluencia de factores estructurales y de agencia en las transiciones escolares ha sido probada. Sin embargo, estos resultados no necesariamente reflejan la conciencia que los jóvenes tienen de dichos condicionantes, así como la medida en que consideran que estos les afectan. Sostiene Miranda Fricker (2017) que cuando una grieta en los recursos de interpretación colectivos hace que una o varias personas se encuentren en posición de desventaja con respecto a la comprensión de sus propias experiencias sociales, está tenien…

Current agri-environmental policies dismiss varied perceptions and discourses on management of traditional rural biotopes

2017

Abstract Traditional rural biotopes (TRBs) are threatened habitats that host significant biodiversity and several ecosystem services, and depend on active management such as low-intensity grazing. The current study explores private landowners’ decision-making on TRB management and abandonment within a social-ecological system framework. We provide insight into supporting resilience of TRB systems in the face of agricultural modernization. Using a mixed methods approach with content analysis and Q analysis, we demonstrate that TRB management fosters cultural, biological, aesthetic, and utilitarian values. These are reflected in different ways through conservationist’s, profit-oriented farmer…

Violencia y transformación del habitus periodístico en Veracruz:caso Notiver (2011-2013)

2016

En este articulo se pretende dar cuenta de la transformacion que han tenido las practicas periodisticas en la zona conurbada de Veracruz-Boca del Rio, entre 2011 y 2013, periodo en el que fueron asesinados nueve periodistas en el estado, tan solo en esos dos anos. Se da seguimiento a los articulos publicados en la seccion de nota roja del diario Notive r, donde laboraba la mayor parte de los periodistas asesinados en dicho periodo. Con el analisis realizado a estas notas, ademas de las entrevistas con los directivos del diario, se corrobora que hubo una transformacion importante en las representaciones de la violencia en el diario, pasando de la “nota roja” a la “nota rosa”, como los mismos…

Sleep bruxism. Conceptual review and update

2010

Sleep bruxism (SB) is a parafunctional oromotor habit that can sometimes pose a threat to the integrity of the structures of the masticatory system if the magnitude and direction of the forces exerted exceed the system?s adaptive capacity. Over the years science has tried to provide a consistent explanation of the etiopathogenesis and physiopathology of SB, although the pathophysiological mechanisms are even now not yet fully understood. There is at present no specific, effective treatment to eliminate the habit of bruxism permanently. There are only palliative therapeutic alternatives steered at preventing the pathological effects of SB on the stomatognathic system and alleviating the nega…

Data from: Recolonization after habitat restoration leads to decreased genetic variation in populations of a terrestrial orchid

2012

Colonization is crucial to habitat restoration projects that rely on the spontaneous regeneration of the original vegetation. However, as a previously declining plant species spreads again, the likelihood of founder effects increases through recurrent population founding and associated serial bottlenecks. We related AFLP genetic variation and fitness of all extant populations of the outcrossing terrestrial orchid Dactylorhiza incarnata in an isolated coastal dune complex to colonization history. Around 1970, D. incarnata suffered a severe bottleneck yet eventually persisted and gradually spread throughout the spatially segregated dune slacks, aided by the restoration of an open vegetation. …

Data from: Wood-inhabiting fungi with tight associations with other species have declined as a response to forest management

2016

Research on mutualistic and antagonistic networks, such as plant–pollinator and host–parasite networks, has shown that species interactions can influence and be influenced by the responses of species to environmental perturbations. Here we examine whether results obtained for directly observable networks generalize to more complex networks in which species interactions cannot be observed directly. As a case study, we consider data on the occurrences of 98 wood-inhabiting fungal species in managed and natural forests. We specifically ask if and how much the positions of wood-inhabiting fungal species within the interaction networks influence their responses to forest management. For this, we…

Data from: The dual role of rivers in facilitating or hindering movements of the false heath fritillary butterfly

2016

Background: Species movement responses to landscape structures have been studied using a variety of methods, but movement research is still in need of simple methods that help predicting and comparing movements across structurally different landscapes. We demonstrate how habitat-specific movement models can be used to disentangle causes of differentiated movement patterns in structurally different landscapes and to predict movement patterns in altered and artificial landscapes. In our case study, we studied the role of riparian landscapes to the persistence of the endangered false heath fritillary butterfly (Melitaea diamina) in its newly discovered coastal distribution region in Finland. W…

Data from: Habitat discontinuities separate genetically divergent populations of a rocky shore marine fish

2017

Habitat fragmentation has been suggested to be responsible for major genetic differentiations in a range of marine organisms. In this study, we combined genetic data and environmental information to unravel the relative role of geography and habitat heterogeneity on patterns of genetic population structure of corkwing wrasse (Symphodus melops), a rocky shore species at the northern limit of its distribution range in Scandinavia. Our results revealed a major genetic break separating populations inhabiting the western and southern coasts of Norway. This genetic break coincides with the longest stretch of sand in the whole study area, suggesting habitat fragmentation as a major driver of genet…

Data from: Patterns of ecological diversification in thelodonts

2018

Here we explore the spatial, temporal and phylogenetic patterns of ecological diversification for the entire clade of thelodonts, one of the earliest groups of vertebrates and longest lasting of the Palaeozoic agnathans in the fossil record. Parsimony and maximum-likelihood methods are used to reconstruct ancestral states of their geographical distributions, habitats and lifestyles. Our results support the concept that thelodonts originated during the Middle?–Late Ordovician probably in marine open waters of Laurasia, with a demersal lifestyle on hard substrates being the ancestral condition for the whole clade. Later, thelodonts underwent a complex ecological diversification and palaeobiog…
