The popular narrative of Wisconsin’s collective bargaining battle started out being about money. Should public employees pay more toward their healthcare? Can school districts offset state aid cuts using the additional revenue from employee healthcare contributions? Does collective bargaining have a cost? This article gives an overview of Wisconsin school boards, explains exactly how Act 10 increased their power, demonstrates why and how improved school board governance can have an impact on student achievement, reviews the changes Wisconsin school boards are making because of Act 10, and provides policy recommendations to improve both board governance behaviors, and the quality of policies enacted by school boards in the postcollective bargaining era. 相似文献

Erinnerungskultur (culture of remembrance) is a widely discussed notion in German historiography. First, the meaning of Erinnerungskultur, including the specific role of academic historiography of sport, is described and explained with respect to sport and sport historiography. One main objective is to reveal the diversity of cultures of sport history and the specific obligations of academic historiography. Second, the actors of sport memories and/or Traditionspflege (heritage) are characterised, and, third, some controversial and perennial debates that permeate German sports history are explained and interpreted, especially that of Carl Diem, internationally known as ‘Mister Olympics’ of 1936. All in all, the paper provides an overview of the mainstreams, cultures and politics of history in Germany with respect to sport. 相似文献

Tennis is an activity requiring both endurance and anaerobic components, which could have immunosuppressive effects postexercise. Purpose The purpose of this investigation was to determine the effect of a simulated tennis match on apoptotic and migratory markers on lymphocyte subsets. Method Male high school (n = 5) and college (n = 3) tennis players (M age = 18.9 ± 3.3 years) completed 10 sets of a tennis protocol including serves, forehand strokes, and backhand groundstrokes with 1-min rest periods between sets. Apoptosis antigen 1 receptor (CD95) and chemokine receptor fractalkine (CX3CR1) expression was analyzed on helper T lymphocytes (CD4+), cytotoxic T lymphocytes (CD8+), and B lymphocytes (CD19+) twice, at resting baseline and immediately after all 10 sets of the tennis protocol. Results An increase was observed in each lymphocyte subtype (p < .02, effect size = .41), and comparison of absolute changes revealed increases in CD4+/CD95+, CD8+/CD95+, and CD8+/CX3CR1 lymphocytes following the tennis protocol (p < .01, effect size = .43), but not in CD19+ cells. Conclusions A simulated tennis match has adequate intensity to induce immune modulations in terms of increased cell death and cellular migration in T lymphocyte subsets. Lymphocytopenia following tennis play is influenced by both apoptotic and migratory mechanisms. 相似文献

When upset with a relational partner, intimates often enact the silent treatment, although it can harm their relationships. This study investigates the degree to which relational commitment predicts a person's self-reported use of the silent treatment. Undergraduate daters indicated their relational commitment, their use of the silent treatment when upset with their partner, and what they do if the partner asks if they are upset. Relational commitment was negatively related to using the silent treatment and stonewalling when the partner asked if there was a problem. Relational commitment was only positively related to admitting being upset when the partner asked if there was a problem. Study limitations and future research implications are discussed. 相似文献
