Cholla infestations can be problematic on rangelands in North America, Australia, Africa, and Europe, and treatment options for this plant are limited because of its ability to resprout from broken stem fragments. We investigated dragged-rail treatments, where iron rails are dragged across the rangeland by tractor and knock plants over while uprooting them, as a treatment option for tree cholla in southeast New Mexico. Railing effectively controlled tree cholla plants over 0.5 m tall, but did not effectively control plants smaller than 0.5 m. Nevertheless, treatment did effectively reduce overall cholla density: Treated areas averaged 40 to 50 plants ha−1, whereas nontreated areas averaged over 350 plants ha−1. Railing can be an effective means of cholla control, especially if followed by another treatment, such as prescribed fire, that is known to be effective against the smaller sizes of cholla.

Alligatorweed, waterhyacinth, and hydrilla are three nonnative aquatic species of concern in the Ross Barnett Reservoir near Jackson, MS. Point-intercept surveys were conducted on the reservoir from 2005 to 2010 to monitor native and nonnative species' distributions and assess herbicide treatment efficacy across the reservoir. Foliar applications of 2,4-D, glyphosate, imazapyr, and diquat were made during summer months for emergent and free-floating vegetation, whereas submersed applications of liquid copper and granular fluridone were applied in spring and late summer for subsurface hydrilla populations. American lotus is the native species that has been observed the most throughout the survey years, with occurrence frequencies averaging between 17 and 27%. Alligatorweed populations significantly decreased from 21% in 2005 to 4% in 2006; however, they consistently increased in the next 4 yr to 12% occurrence in 2010. Waterhyacinth occurrence has remained relatively constant over the study period, averaging below 10% occurrence. Hydrilla was discovered in the reservoir in late 2005 and has remained below 2% in frequency of occurrence since 2006. Suppression of these nonnative species has been attributed to rigorous monitoring and herbicide applications conducted on the reservoir since 2005. A logistic regression model indicated that as native species richness increased, the likelihood of a nonnative species occurring also increased.

In today’s global business environment teams are fast becoming the norm. Collaboration is an essential factor in leveraging team effectiveness, and organizations are looking for strategies to increase collaboration among their teams. In this study, we administered an eSurvey to 308 professionals working in face-to-face and virtual teams to investigate emotional intelligence and strengths, opportunities, aspirations, and results as strategies to support the collaborative process. Results found the regression of collaboration on emotional intelligence (controlling for age, ethnicity, and education) was significant (p<.01). Results also found a significant indirect effect between emotional intelligence and collaboration as mediated by strengths, opportunities, aspirations, and results (β=0.110, Z=2.444). We focus on understanding the effect of emotional intelligence on team collaboration as mediated by strengths, opportunities, aspirations, and results. Recommendations are provided for increasing emotional intelligence and strengths, opportunities, aspirations, and results among team members. Our research has important implications for teams and their pervasive use in business.

Shakespeare's most innovative genre was the history play, because it has no precedent in either classical or medieval tradition. In contrast to the focused teleology of Christian medieval drama, Shakespeare's history plays manifest an implicit idea of history that was secular, political, and open-ended. They emphasize human action in a political arena, where the criterion for success is the ability to act in time, without regard to one's spiritual state. Time determines royal succession, which is the focus of all Shakespeare's history plays, as it was the focus of political concern in England in the 1590s, when the plays were written. His emphasis on time and royal succession distinguishes his implied political theory from the moralism and authoritarianism of official Tudor state doctrine on one hand and from the pragmatism of Machiavelli on the other.
