Two experiments compared alternative minimal group induction procedures involving (a) memorization of novel in-group names or (b) random categorization to (c) the traditional procedure based on ostensibly meaningful but deception-based categorization. Experiment 1 revealed comparable in-group attitude and identification effects across the three procedures on explicit measures, but significantly...

The density at which a crop is grown is known to affect its growth and quality, but little is known about how plant density affects the growth of native perennial forage grasses. The objectives were to investigate the effects of plant population density on the forage yield, forage quality, and plant canopy structure of two native bluestem species. Big bluestem (Andropogon gerardii Vitman) and s...

This paper will introduce a theory of emergent animal social complexity using various results from computational models and empirical results. These results will be organized into a vertical model of social complexity. This will support the perspective that social complexity is in essence an emergent phenomenon while helping to answer of analysis larger than the individual organism. The second ...

We thank Black (2008) for his thoughtful assembly of diverse perspectives including ours on why another disastrous Mississippi River flood occurred so soon after 1993. We have an update that elucidates and quantifies several key points of his article, particularly that a) flood frequency and heights are increasing, b) water levels for regulatory “100-year” floods are profoundly underestimated, ...

Increasing atmospheric carbon dioxide (CO2) likely will affect future water requirements of most plants, including agricultural crops. This research quantifies such effects on the energy balance and evapotranspiration (ET) of sorghum (Sorghum bicolor (L.) Möench, a C4 grain crop) using a residual energy balance approach. During the summer and autumn of 1998 and 1999, sorghum was grown under fre...

Background Approximately 30% of patients (pts) with plaque psoriasis (PsO) develop psoriatic arthritis (PsA) 1 , which is associated high Psoriasis Area and Severity Index (PASI) nail involvement. The Study Health Outcomes (PSoHO) a 3-year (yr), international, prospective, observational cohort study comparing the effectiveness anti-IL-17A biologics to all other approved in pts moderate-to-sever...

The last decade has witnessed a resurrection of historical decadal geodetic rates provide a reasonable proxy for the long-term rates of plate motions (Donnellan et al., 1993; concepts and controversies concerning the evolution of landscapes in active tectonic regimes. New insights into Abdrakhmatov et al., 1996). If true, geodetic measurements provide an accurate snapshot of the tectonic forcin...
