This paper outlines a history of the union organizing of the American Newspaper Guild at Thomson Newspapers’ Peterborough Examiner in Canada from 1968 to 1969. It examines the communication tools that union members used to facilitate this labor organizing and “bite back” at the profitable Thomson chain. Peterborough newsworkers went on strike from November 1968 to April 1969 over union recognition. During the strike, the union members built an unprecedented alliance with Ontario university students, collaboratively launching a strike newspaper called the Peterborough Free Press. Expanding on the concept of temporary labor convergence, this paper considers how strike newspapers can be seen as a form of alternative journalism that newsworkers use as a campaigning tool to communicate their struggles to the public and put pressure on news corporations to bargain with them. This case study is situated in the local institutional contexts of labor relations at the Peterborough Examiner and the news industry in Peterborough, where Thomson Newspapers had a media monopoly. It is based on labor standpoint and signal juncture analyses of union archival documents and newspaper content. The research ultimately suggests that newsworkers should not only focus on communication tools but also build bridges with community members. 相似文献

ABSTRACT Participation in youth sport is positively associated with physical fitness and performance. The purpose of the current study was to examine if physical fitness measures during childhood and early adolescence predicted high school sport participation. Participants included youth in the Michigan State University Motor Performance Study. Measures consisted of the endurance shuttle run, Wells sit-and-reach, jump and reach, standing long jump, agility shuttle run and 30-yard dash. Individual, generalized estimating equation models were used to estimate the association between each measure and the odds of participating in high school sport. For both sexes, the endurance shuttle run and agility shuttle run were related to sport participation. For boys only, the long jump and 30-yard dash were also associated with sport participation. Better physical fitness and performance across several dimensions in childhood, including those related to motor skills, enhanced the likelihood of sport participation in high school. 相似文献

This study targeted to examine the effect of the ToyBox-intervention, a kindergarten-based, family-involved intervention, aiming to improve preschooler’s energy-related behaviours (e.g., physical activity) on motor performance ability. Physical activity sessions, classroom activities, environmental changes and tools for parents were the components of the 1-year intervention. The intervention and control were cluster-randomised, and children’s anthropometry and two motor test items (jumping from side to side, JSS and standing long jump, SLJ) were assessed. A total of 1293 (4.6 ± 0.69 years; 52% boys) from 45 kindergartens in Germany were included (intervention, n = 863; control, n = 430). The effect was assessed using generalised estimating equation. The intervention group showed a better improvement in JSS (Estimate 2.19 jumps, P = 0.01) and tended to improve better in SLJ (Estimate 2.73 cm, P = 0.08). The intervention was more effective in boys with respect to SLJ (P of interaction effect = 0.01). Children aged <4.5 years did not show a significant benefit while older children improved (JSS, Estimate 3.38 jumps, P = 0.004; SLJ, Estimate 4.18 cm, P = 0.04). Children with low socio-economic status improved in JSS (Estimate 5.98 jumps, P = 0.0001). The ToyBox-intervention offers an effective strategy to improve specific components of motor performance ability in early childhood. Future programmes should consider additional strategies specifically targeting girls and younger aged children.
