Still going strong…here are the highlights from several sessions held on Day 4: John Eme (California State University, San Marcos) presented data testing the effects of varying temperatures mimicking overwintering conditions on embryonic development of Lake whitefish. He found that indeed exposure to variable incubation temperatures between 2-8 deg C resulted in increased mortality. Moreover, the embryos hatched earlier and were smaller than animals exposed to constant temperatures. Nariman Hossein-Javaheri et al., (University of Toronto) discussed how goldfish (Carassius auratus) are anoxia tolerant, meaning they can tolerate conditions in which there is no oxygen in the water. They do this by lowering brain electrical activity to help prevent tissue death. , Melanie Laskbrook, Susana Rosales, Jordan Wakefield, Gregory Florant, and Adam Chicco (Colorado State University) presented data examining metabolic changes occurring in golden-mantled ground squirrels as they prepare to hibernate. What she found is that exposing obese (ready to hibernate) animals to cold 15 deg C, prevented lipid breakdown and therefore promoted storage in preparation for the long, cold winter fast. James Sargent, Jacob Campbell, and Jon Harrison (Arizona State University) showed that the variations in ability to tolerate anoxic environments is very similar between fruit flies and mammals. This similarity may make fruit flies good models in which to study stroke and heart disease., conditions associated with low oxygen delivery to tissues. Arthur Woods (University of Montana) demonstrated data that suggests marine invertebrates living in polar regions are able to grow large because oxygen supply is high but the demand for oxygen is low. Kelly Florimon, Cassondra Williams (University of California, Irvine) examined red-eared sliders (above) to determine how the animals respond to flight-or-fright stimuli. Noise disturbance increased heart rate in turtles, which is a response similar to humans. The response in crocodiles, however, is different wherein the animals slow down heart rate in response to a frightening stimuli. Roy Weber, Jennifer Jarvis, Angela Fago, and Nigel Bennett (Aarhus University) showed that African mole rats, which live underground in hypoxic (low oxygen) environments experience conditions similar to animals that live at high altitude. Are they thus adapted to potentially live in either location?

Anthropogenic nitrogen (N) deposition has caused a decline in native plant species and an increase in exotic plant species in many terrestrial ecosystems; however, vegetation change depends on the rate and/or duration of N input, individual species responses, interactions with other resources, and ecosystem properties such as species richness and canopy cover, soil texture, pH, and/or disturbance regime. Native shrub and exotic forb responses to N enrichment were evaluated over a 13-year field experiment in a mature coastal sage scrub (CSS) shrubland of southern California to test the hypothesis that dry-season N input will cause a decline in native shrubs and an increase in exotic annuals. Nitrogen enrichment caused the dominant native shrubs, Artemisia californica and Salvia mellifera, to respond differently, with A. californica initially increasing with N input but declining thereafter and S. mellifera declining consistently over the 13-year-period. Both species exhibited higher canopy dieback during drought conditions, especially in N plots. Brassica nigra, an exotic annual, invaded N plots significantly more than control plots, but only after 10 years of N addition and a prolonged drought, which increased native shrub canopy dieback. These results indicate a possible synergism between N enrichment and drought on native shrub and exotic forb abundance, which would have important implications for plant diversity in semi-arid shrublands of southwest US that are anticipated to experience an increase in anthropogenic N enrichment and the frequency and duration of drought. © 2017, Springer-Verlag Berlin Heidelberg.

Environmental perception is prerequisite to most vertebrate behavior and its modern investigation initiated the founding of experimental psychology. Navigation costs may affect environmental perception, such as overestimating distances while encumbered (Solomon, 1949). However, little is known about how this occurs in real-world navigation or how it may have evolved. We manipulated the most commonly navigated surfaces with a non-intuitive cost derived from evolved navigation theory. Observers in realistic settings unknowingly overestimated horizontal distances that contained a risk of falling and did so by the relative degree of falling risk. This manipulation produced previously unknown, large magnitude illusions in everyday vision in the environments most commonly navigated by humans. These results bear upon predictions from multiple fundamental theories of visual cognition. © 2010 Elsevier B.V.

Zerocycle, creator of the proprietary Resident Engagement Platform that uses rich data analytics and behavioral science technology to help local governments increase recycling, reduce waste and dramatically lower disposal costs, announced today that the results of its pilot project with the City of Fremont, CA exceeded expectations. The pilot project, which took place in June 2016 and was led by the California-based public agency StopWaste and community-based marketing firm Action Research, tested three programs vs. a control group to identify effective outreach strategies for reducing the amount of organic material placed in household trash by Fremont residents: 1) Zerocycle’s unique Neighborhood Waste Report (NWR); 2) hangtags; 3) a kitchen countertop pail with 30 compostable bags. The control group received no outreach materials. While each outreach strategy helped reduce the amount of compostable material lost to the landfill, the positive impact of Zerocycle’s NWR was especially notable and included: A 41% reduction in the amount of food scraps in the trash A 28% reduction in organic material in the trash A 13% reduction in overall trash bin weight These improvements are welcome news for all parties and stakeholders, especially Mayors and local government officials in Solid Waste, Public Works, and Sustainability Departments who need to reach aggressive waste reduction goals. The full report entitled “Pilot Program: StopWaste City of Fremont Residential Food Scrap Recycling” is available here. “We’re very excited about the outstanding results of this pilot project, and the potential to help local governments save millions of dollars in disposal fees while encouraging residents to reduce their environmental footprint,” commented Hunter Hayes, Zerocycle’s Co-Founder and CEO. “The national recycling rate of about 34 percent has been flat over the last few years, and the effectiveness of educational-only campaigns has leveled off. That’s where Zerocycle’s approach is revolutionary. We fuse industry-first data analytics with powerful behavioral science outreach techniques such as normative social influence to create friendly competition, and motivate individuals, families and neighborhoods to recycle more.” “In waste audits conducted by Action Research and other organizations around the country, organic waste is shown time and time again to be a crucial factor in diverting waste from landfills,” commented Lori Large, Director of Research Operations at Action Research. “Nearly a third of our waste stream is compostable. Normative feedback, in the form provided by Zerocycle’s Resident Engagement Platform, is a powerful social science tool that can be used to reduce waste by engaging residents in proper disposal behaviors.” “We know that people are interested in recycling, but just sending them educational materials or reminding them to do the right thing isn’t enough,” commented Wesley Schultz, Ph.D., Scientific Advisor for Zerocycle, and a Professor of Psychology at California State University, San Marcos. “However, we have seen that when residents compare their recycling levels to neighbors, this creates a sense of community connection and collective action that can ultimately result in lasting behavioral changes.” For all other details and information, including media and interview requests, contact Rich Rothman, Zerocycle’s VP of Sales at rich(at)zerocycle(dot)co. Zerocycle is a data analytics company that provides local governments with an innovative Resident Engagement Platform (REP) that significantly increases diversion rates and reduces waste. The heart of the REP is Zerocycle’s Neighborhood Waste Report (NWR), which is delivered to residents in strategic areas of the city and features full-color maps, neighborhood rankings, and other insights on recycling. The NWR leverages behavioral psychology techniques, including normative messaging, to create friendly competition and drive measurable change in waste, recycling, and composting behavior.

Inattentional blindness is the failure to notice unexpected objects in a visual scene while engaging in an attention-demanding task. We examined the effects of animacy and perceptual load on inattentional blindness. Participants searched for a category exemplar under low or high perceptual load. On the last trial, the participants were exposed to an unexpected object that was either animate or inanimate. Unexpected objects were detected more frequently when they were animate rather than inanimate, and more frequently with low than with high perceptual loads. We also measured working memory capacity and found that it predicted the detection of unexpected objects, but only with high perceptual loads. The results are consistent with the animate-monitoring hypothesis, which suggests that animate objects capture attention because of the importance of the detection of animate objects in ancestral hunter-gatherer environments. © 2013 Psychonomic Society, Inc.

The growing use of mindfulness and contemplative methods in treating mental illness and addiction has elicited interest in their relationship to the comprehensive Buddhist theory and practices that underlie them. This article discusses traditional Buddhist meta-theoretical assumptions regarding ontology and epistemology, along with its perspectives on the self, human functioning, dissatisfaction and dysfunction, and the relationship to mindfulness human well-being. It then describes contemporary elaboration of the concepts of mindfulness and psychological well-being by Buddhist-oriented practitioners and provides examples of therapeutic methods that incorporate these views and techniques. © 2014 Springer Science+Business Media New York.

Annual Review of Physical Chemistry | Year: 2012
Historically, the physical chemistry of isotope effects and precise measurements in samples from nature have provided information on processes that could not have been obtained otherwise. With the discovery of a mass-independent isotopic fractionation during the formation of ozone, a new physical chemical basis for isotope effects required development. Combined theoretical and experimental developments have broadened this understanding and extended the range of chemical systems where these unique effects occur. Simultaneously, the application of mass-independent isotopic measurements to an extensive range of both terrestrial and extraterrestrial systems has furthered the understanding of events such as solar system origin and evolution and planetary atmospheric chemistry, present and past. © Copyright ©2012 by Annual Reviews.

Current pain and headache reports | Year: 2013
A variety of biological, psychological, and social factors interact to influence pain. This article focuses on two distinct, but connected, psychological factors--positive personality traits and pain catastrophizing--and their link with pain perception in healthy and clinical populations. First, we review the protective link between positive personality traits, such as optimism, hope, and self-efficacy, and pain perception. Second, we provide evidence of the well-established relationship between pain catastrophizing and pain perception and other related outcomes. Third, we outline the inverse relationship between positive traits and pain catastrophizing, and offer a model that explains the inverse link between positive traits and pain perception through lower pain catastrophizing. Finally, we discuss clinical practice recommendations based on the aforementioned relationships.

The study addressed two limitations of previous research on factors related to teachers' integration of technology in their teaching. It attempted to test a structural equation model (SEM) of the relationships among a set of variables influencing preservice teachers' use of technology specifically to support student-centered learning. A review of literature led to a path model that provided the design and analysis for the study, which involved 206 preservice teachers in the United States. The results show that the proposed model had a moderate fit to the observed data, and a more parsimonious model was found to have a better fit. In addition, preservice teachers' self-efficacy of teaching with technology had the strongest influence on technology use, which was mediated by their perceived value of teaching and learning with technology. School's contextual factors had moderate influence on technology use. Moreover, the effect of preservice teachers' training on student-centered technology use was mediated by both perceived value and self-efficacy of technology. The implications for teacher preparation include close collaboration between teacher education program and field experience, focusing on specific technology uses. © 2009 Elsevier Ltd.
