A population-based model was developed to simulate the evolution of glyphosate resistance in populations of Amaranthus palmeri. Model parameters were derived from published and unpublished sources, and the model was implemented using previously established principles and methods. Sensitivity analyses indicated that the model was sensitive to variations in population size, mutation rate and seed bank dynamics. A distribution was assigned to these parameters and Monte Carlo type simulations were performed. Simulation results are therefore derived from a range of possible input parameters, enabling the risk of resistance evolution to be assessed when parameter values were unknown, uncertain or variable. In the 'worst-case' of five annual glyphosate applications in continuous glyphosate resistant cotton, evolution of glyphosate resistance was predicted in 39% of populations after 5years and in c.60% of populations after 10years. These results are consistent with observations of the timescale for evolution of glyphosate resistance in A. palmeri in the field. The main drivers for glyphosate resistance evolution were selection pressure and population size, the greatest risks being associated with the largest A. palmeri populations. Risks of resistance were reduced when one of the five glyphosate applications was replaced by another mode of action with identical efficacy. However, not all glyphosate applications exerted the same selection pressure. Application of a soil residual herbicide at the time of crop sowing can provide control of A. palmeri well into the growing season and significantly reduced the rate and risk of glyphosate resistance evolution. © 2010 The Authors.

Great strides have been made in identifying the expertise needed by strength coaches to be competent in their jobs. As our profession moves forward, we need to continue to refine and standardize the knowledge base of the field. A method helpful in accomplishing this outcome would be to develop a model to guide our educational efforts. The model being put forth is known as the "program for effective teaching". This model could serve as a framework for educational programs in the profession while at the same time being a standard to aspire to by those providing direct services to athletes. © National Strength and Conditioning Association.

Self-thinning of forest stands is one of the clearest and best-documented examples of natural selection. Besides their theoretical interest, understanding of self-thinning is important for forest practice because it produces estimates of stand density and stocking. There is a considerable diversity of views on the processes causing self-thinning, predicting variables, and analytical form of models. The most popular model was proposed by Reineke (J Agric Res 46(7):627-638, 1933) over 70 years ago. This study compares existing models of self-thinning and provides evidence that the virtually unknown model developed by Artur Nilson describes self-thinning more realistically than Reineke's. While in the Reineke model the rate of mortality (the slope of self-thinning line) is assumed to be constant, it changes from 0 to -2 in Nilson's model. As a result, Nilson's model is slightly but consistently more accurate than Reineke's. Although both models are empirical, their analysis suggests several general conclusions about self-thinning. © 2010 Springer-Verlag.

Cooperation and competition have emerged as factors that may affect video game players. Competition consistently has been found to elicit increased aggression whilst cooperation has been found to mitigate aggression and increase cooperative behaviors after game play. Of interest is the effect of the relationship between players (friend vs. stranger) in cooperative and competitive multiplayer contexts. In this study, we considered how game goal structure - competition or cooperation - and relationships between players - friend or stranger - affect aggression and cooperative behaviors. Compared with competition, cooperative play resulted in significantly more cooperative behaviors in a modified Prisoner's Dilemma task. However, neither competitive nor cooperative goal structures significantly increased state hostility, suggesting that altering players' gaming goals (e.g. competition or cooperation) may not be enough to elicit strong affective aggression. Additionally, cooperative game play was found to predict increased cooperative behaviors and trust in their partner. Implications of the findings are discussed. © 2014 Elsevier Ltd.

This investigation consisted of a job analysis of 6 National Collegiate Athletic Association (NCAA) Division I female strength and conditioning coaches. Each coach was employed at universities competing within the Football Bowl Subdivision. All subjects in the survey were responsible for providing strength and conditioning services to their institution's athletic programs. The procedures used for the gathering of data involved a questionnaire followed by a semi-structured interview. The purpose of this format was to use the semi-structured interview to delve more deeply into the issues raised by the questionnaire. Evidence was obtained related to demographic data; major job duties; relationships with supervisors, fellow strength coaches, and the sport coaches with whom they work; and the effects the job has on their spouse and other family members. All the participants in the study were white with an average age of 31.6 years. Their average time spent in the profession was 8 years, and the average time spent in their current employment was 5 years. Overall, the job satisfaction for the group was high. Five of the subjects held master's degrees, and all participants held relevant certifications in the field. The coaches primarily provided services to athletes participating in women's sports at their respective universities. © 2013 National Strength and Conditioning Association.
