plastic multicellular development of myxococcus xanthus genotype environment interactions in a Physical gradient
Royal Society Open Science, 2019Co-Authors: Natsuko Riverayoshida, Alejandro V Arzola, Juan Arias A Del Angel, Alessio Franci, Michael Travisano, Ana E Escalante, Mariana BenitezAbstract:In order to investigate the contribution of the Physical environment to variation in multicellular development of Myxococcus xanthus, phenotypes developed by different genotypes in a gradient of substrate stiffness conditions were quantitatively characterized. Statistical analysis showed that plastic phenotypes result from the genotype, the substrate conditions and the interaction between them. Also, phenotypes were expressed in two distinguishable scales, the individual and the population levels, and the interaction with the environment showed scale and trait specificity. Overall, our results highlight the constructive role of the Physical Context in the development of microbial multicellularity, with both ecological and evolutionary implications.

the impact of social factors and consumer behavior on carbon dioxide emissions in the united kingdom a regression based on input output and geodemographic consumer segmentation data
Journal of Industrial Ecology, 2010Co-Authors: Giovanni Baiocchi, Jan Minx, Klaus HubacekAbstract:In this article we apply geodemographic consumer segmentation data in an input−output framework to understand the direct and indirect carbon dioxide (CO) emissions associated with consumer behavior of different lifestyles in the United Kingdom. In a subsequent regression analysis, we utilize the lifestyle segments contained in the dataset to control for aspects of behavioral differences related to lifestyles in an analysis of the impact of various socioeconomic variables on CO emissions, such as individual aspirations and people's attitudes toward the environment, as well as the Physical Context in which people act. This approach enables us to (1) test for the significance of lifestyles in determining CO emissions, (2) quantify the importance of a variety of individual socioeconomic determinants, and (3) provide a visual representation of “where” the various factors exert the greatest impact, by exploiting the spatial information contained in the lifestyle data. Our results indicate the importance of consumer behavior and lifestyles in understanding CO emissions in the United Kingdom. Across lifestyle groups, CO emissions can vary by a factor of between 2 and 3. Our regression results provide support for the idea that sociodemographic variables are important in explaining emissions. For instance, controlling for lifestyles and other determinants, we find that emissions are increasing with income and decreasing with education. Using the spatial information, we illustrate how the lifestyle mix of households in the United Kingdom affects the geographic distribution of environmental impacts.

Contextual control of appetitive conditioning influence of a Contextual stimulus generated by a partial reinforcement procedure
Quarterly Journal of Experimental Psychology Section B-comparative and Physiological Psychology, 2001Co-Authors: Mark E. Bouton, Ceyhun SunsayAbstract:Three experiments with rat subjects examined the effects of a Context switch after conditioning treatments in which the conditioned stimulus (CS) was either paired with food on every presentation (continuous reinforcement) or on some of its presentations (partial reinforcement). In each experiment, a target CS was given one of these treatments in Context A, and another CS was given a treatment during sessions that were intermixed in Context B. Final tests of the target CS in Context A and Context B often revealed no loss of responding with the switch to B. However, a loss was observed when partial reinforcement had been associated with Context A and continuous reinforcement had been associated with Context B. Those conditions caused equal decrements in responding to partially reinforced and continuously reinforced targets. The results suggest that under the present conditions partial reinforcement can generate a Contextual stimulus that becomes associated with the Physical Context and controls responding ...

Context change and retention interval can have additive rather than interactive effects after taste aversion extinction
Psychonomic Bulletin & Review, 1998Co-Authors: Juan M. Rosas, Mark E. BoutonAbstract:Spontaneous forgetting is often attributed to retrieval failure caused by natural changes in the background Context that occur over time. However, some investigators have argued that the Context-change account of forgetting is paradoxical, because Context-change effects themselves decrease over time. To resolve the paradox, we have suggested that organisms may merely forget the Physical Context as the temporal Context in which it is embedded changes; this explanation accepts a fundamental similarity between time and Physical Context. The present experiment tested an implication of this analysis by examining the interaction between retention interval and Context change in rats after a taste aversion was conditioned and then extinguished. Importantly, subjects tested at the longer (24-day) retention interval received reminder exposure to the Physical Contexts before testing. Under these conditions, retention interval and Context change both caused relapse of the extinguished aversion (spontaneous recovery and renewal, respectively), and the strongest overall relapse was observed when the two treatments were combined. Such additivity (rather than interactivity) is consistent with a Context-change account of forgetting and sets the stage for resolution of the Context-forgetting paradox.

Additivity of the effects of retention interval and Context change on latent inhibition: toward resolution of the Context forgetting paradox.
Journal of experimental psychology. Animal behavior processes, 1997Co-Authors: Juan M. Rosas, Mark E. BoutonAbstract:Three experiments with rats examined retention interval and Context switch effects factorially in the latent inhibition paradigm. In Experiment 1, a 28-day retention interval abolished a Context switch effect on latent inhibition. In Experiment 2, re-exposure to the Contexts before conditioning re-established the Context switch effect at the 28-day interval. In this case, the retention interval and Context switch effects were additive: Latent inhibition was weakest when the retention interval and Context switch were combined. Experiment 3 replicated the Context switch effect at the 28-day interval. The results suggest that Context switch and retention interval effects may be based on the same process. Context switch effects may weaken over time because Physical Contexts are embedded in superordinate temporal Contexts; animals fail to retrieve Physical Context when the temporal Context changes. This view helps resolve a paradox that has been noted for Contextual change theories of forgetting.
