The effects of climatic factors and vegetation type on evapotranspiration (E) and water use efficiency (WUE) were analyzed using tower-based eddy-covariance (EC) data for nine mature forest sites, two peatland sites and one grassland site across an east-west continental-scale transect in Canada during the period 2003-2006. The seasonal pattern of E was closely linked to growing-season length and rainfall distribution. Although annual precipitation (P) during the observation period was highly variable among sites (250-1450mm), minimum annual E was not less than 200mm and was limited to 400-500mm where annual P exceeded 700mm. Site-specific interannual variability in E could be explained by either changes in total P or variations in solar irradiance. A highly positive linear correlation was found between monthly mean values of E and net radiation (R n) at the grassland site (AB-GRL), the two peatland sites (AB-WPL and ON-EPL), and only one of the forest sites (coastal Douglas-fir, BC-DF49) whereas a hysteretic relationship at the other forest sites indicated that E lagged behind the typical seasonal progression of R n. Results of a cross-correlation analysis between daily (24-h) E and R n revealed that site-specific lag times were between 10 and 40 days depending on the lag of vapour pressure deficit (D) behind R n and the decoupling coefficient, Ω. There was significant seasonal variation in daytime mean dry-foliage Priestley-Taylor α with maxima occurring in the growing season at all sites except BC-DF49 where it was relatively constant (∼0.55) throughout all years. Annual means of daytime dry-foliage α mostly ranging between 0.5 and 0.7 implied stomatal limitation to transpiration. Increasing D significantly decreased canopy conductance (g c) at the forest sites but had little effect at the peatland and grassland sites, while variation in soil water content caused only minor changes in g c. At all sites, a strong linear correlation between monthly mean values of gross primary production (GPP) and E resulted in water use efficiency being relatively constant. While at most sites, WUE was in the range of 2.6-3.6gCkg -1 H 2O, the BC-DF49 site had the highest WUE of the twelve sites with values near 6.0gCkg -1 H 2O. Of the two peatland sites, AB-WPL, a western treed fen, had a significantly higher WUE (∼3.0gCkg -1 H 2O) than ON-EPL, an eastern ombrotrophic bog (∼1.8gCkg -1 H 2O), which was related to peatland productivity and plant functional type. © 2011 Elsevier B.V.

The small GTPase RhoA and its downstream effectors, ROCK1 and ROCK2, regulate a number of cellular processes, including cell motility, proliferation, survival, and permeability. Pharmacological inhibitors of the Rho pathway reportedly block angiogenesis; however, the molecular details of this inhibition are largely unknown. We demonstrate that vascular endothelial growth factor-A (VEGF) rapidly induces RhoA activation in endothelial cells (ECs). Moreover, the pharmacological inhibition of ROCK1/2 using 10 μM Y-27632 (the IC 50 for this compound in ECs) strongly disrupts vasculogenesis in pluripotent embryonic stem cell cultures, VEGF-mediated regenerative angiogenesis in ex vivo retinal explants, and VEGF-mediated in vitro EC tube formation. Furthermore, using small interfering RNA knockdown and mouse heterozygote knockouts of ROCK1 and ROCK2, we provide data indicating that VEGF-driven angiogenesis is largely mediated through ROCK2. These data demonstrate that Rho/ROCK signaling is an important mediator in a number of angiogenic processes, including EC migration, survival, and cell permeability, and suggest that Rho/ROCK inhibition may prove useful for the treatment of angiogenesis-related disorders. © FASEB.

More accurate estimation of the carbon dioxide flux depends on the improved scientific understanding of the terrestrial carbon cycle. Remote-sensing-based approaches to continental-scale estimation of net ecosystem exchange (NEE) have been developed but coarse spatial resolution is a source of errors. Here we demonstrate a satellite-based method of estimating NEE using Landsat TM/ETM+data and an upscaling framework. The upscaling framework contains flux-footprint climatology modeling, modified regression tree (MRT) analysis and image fusion. By scaling NEE measured at flux towers to landscape and regional scales, this satellite-based method can improve NEE estimation at high spatial-temporal resolution at the landscape scale relative to methods based on MODIS data with coarser spatial-temporal resolution. This method was applied to sixteen flux sites from the Canadian Carbon Program and AmeriFlux networks located in North America, covering forest, grass, and cropland biomes. Compared to a similar method using MODIS data, our estimation is more effective for diagnosing landscape NEE with the same temporal resolution and higher spatial resolution (30m versus 1km) (r2=0.7548 vs. 0.5868, RMSE=1.3979 vs. 1.7497gCm-2day-1, average error=0.8950 vs. 1.0178gCm-2day-1, relative error=0.47 vs. 0.54 for fused Landsat and MODIS imagery, respectively). We also compared the regional NEE estimations using Carbon Tracker, our method and eddy-covariance observations. This study demonstrates that the data-driven satellite-based NEE diagnosed model can be used to upscale eddy-flux observations to landscape scales with high spatial-temporal resolutions. © 2013 Elsevier Inc.

In this article I recount the ways that key concepts in Lacanian psychoanalytic theory-the relationship between language and desire, fantasy and subject formation, ethics and the traversal of fantasy-have enabled a novel methodological approach to activist research. Psychoanalysis allows us to recast research as a process of encountering and traversing fantasies, which is simultaneously a process of engendering new representations, desires, subjectivities, and societies. © 2010 by Association of American Geographers.

Physical Review A - Atomic, Molecular, and Optical Physics | Year: 2010

We study single collisions between spin-polarized positron beams and targets that result in the production of positronium and target ions. We consider unpolarized as well as polarized targets with 0,1, and 2 unpaired electrons. First, we use angular momentum coupling to calculate the spin scattering matrices in all three cases. Then, for some targets, we define an angle β between the polarization vectors of the positron beam and the target, and calculate density matrices whose elements are functions of β. Finally, from the density matrices, we obtain the probabilities of forming para- and ortho-positronium atoms for specific spins of the target ions. We present ratios of para- to ortho-positronium yields as well as total positronium annihilation rates. © 2010 The American Physical Society.

Child Abuse and Neglect | Year: 2010

In the last 10 years, over 80% of adults surveyed report some familiarity with Shaken Baby Syndrome (SBS) and the dangers of shaking infants younger than 2 years of age (Dias et al., 2005; Russell & Britner, 2006). Hence, in the context of SBS prevention, the question of whether caregivers knew the safety risks of shaking an infant becomes less meaningful than questioning whether caregivers have an awareness of alternate responses they could use to respond safely to the relatively normative occurrence of inconsolable crying (Barr, Trent, & Cross, 2006). Objective: The present work is a continuation of efforts to prevent abusive head injury during infancy particular to SBS by raising awareness and provides prevention professionals with a reliable and shorter, single-page version of the Shaken Baby Syndrome Awareness Assessment (Russell & Britner, 2006). Methods: A sample of 370 adults completed the short version of the measure during 2008. Results: Psychometric results, including Cronbach's alphas and Pearson's correlations, are all significant and meet acceptability standards. Conclusion: These results indicate the short version of the measure is ready for use in the prevention field. Practice implications: The Shaken Baby Syndrome Awareness Assessment - short version is best used to support child abuse prevention professionals in engaging caregivers in a conversation about responding to a crying infant safely. By talking about the responses a caregiver might be willing to use in the high-stress context of an infant's inconsolable crying bout, intervention efforts can be tailored to maximize on caregiver strengths and achieve a high degree of goodness of fit with the values held in the care environment. Increasing the goodness of fit between caregivers' values and the steps recommended through an intervention program supports the likelihood that the behavior described in the program's service plan will be used. © 2010 Elsevier Ltd.
