Positive Behavioral Support: Strategies for teachers

Positive behavioral support (PBS) is a comprehensive, research-based proactive approach to behavioral support that endeavors to generate comprehensive change for students with challenging behavior. It involves identifying the purpose of challenging behavior, teaching appropriate alternative responses that serve the same purpose as the challenging behavior, consistently rewarding positive behaviors and minimizing the rewards for challenging behavior, and minimizing the physiological, environmental, and curricular elements that trigger challenging behavior. Proven PBS strategies include altering the classroom environment, increasing predictability and scheduling, increasing choice making, adapting the curriculum, appreciating positive behaviors, and teaching replacement skills. Relevant sources for those interested in implementing PBS are presented

Risk Factors for Campylobacteriosis in Two Washington State Counties with High Numbers of Dairy Farms

Campylobacteriosis is a frequently reported, food-borne, human bacterial disease that can be associated with ruminant reservoirs, although public health messages primarily focus on poultry. In Washington State, the two counties with the highest concentrations of dairy cattle also report the highest incidences of campylobacteriosis. Conditional logistic regression analysis of case-control data from both counties found living or working on a dairy farm (odds ratio [OR], 6.7 [95% confidence interval [CI], 1.7 to 26.4]) and Hispanic ethnicity (OR, 6.4 [95% CI, 3.1 to 13.1]) to have the strongest significant positive associations with campylobacteriosis. When the analysis was restricted to residents of one county, Hispanic ethnicity (OR, 9.3 [95% CI, 3.9 to 22.2]), contact with cattle (OR, 5.0 [95% CI, 1.3 to 19.5]), and pet ownership (OR, 2.6 [95% CI, 1.1 to 6.3]) were found to be independent risk factors for disease. Campylobacter jejuni isolates from human ( n = 65), bovine ( n = 28), and retail poultry ( n = 27) sources from the same counties were compared using multilocus sequence typing. These results indicated that sequence types commonly found in human isolates were also commonly found in bovine isolates. These findings suggest that, in areas with high concentrations of dairy cattle, exposure to dairy cattle may be more important than food-borne exposure to poultry products as a risk for campylobacteriosis
