Stress and Trauma

Toxic stress and trauma are common occurrences that can create physiological and psychological changes with negative short- and long-term effects. Research has clearly established a correlation between adversity and negative outcomes. However, there are a number of factors involved in the development, intensity, and severity of outcomes, specifically the type of stress or trauma experiences, temperament, personality type, repertoire of coping skills, and level of resiliency. This chapter reviews the definitions of different types of stress, the neurological changes that can occur as a result of adversity, common and paradoxical reactions to trauma, and the ability of coping skills and resilience to change the trajectory from negative outcomes to opportunities for positive growth.

This article analyzes the effects of police raids for different types of crime in the most conflictive neighborhoods of Montevideo, Uruguay. Interrupted time-series and intervention models are estimated using different specifications of geographical area where the crackdowns occurred and also different control strategies to produce robust results. The effect of crackdowns on crime reporting is mixed; evidence suggesting crackdowns may produce short- and long-term effects on crime depending on their ability to affect gangs’ competition for the territory and the market. It appears that the effects of raids are sensitive to the context of the criminal situation. Crackdowns are not consistently effective in influencing crime. Evidence shows it is hard to reach levels of critical enforcement through 1-day crackdowns and that crackdowns’ ability to alter drug-market conditions would depend not only on the ability to extract drug dealers from the territory but also in preventing a rapid return.

The short- and long-term effects of preceding crops on damping-off of sugar beet were studied in pot trials in the glasshouse. Of the different types of plants studied, cereals most effectively decreased disease frequency. At the same time cereals on average also decreased the number of Pythium propagules in the soil, this being a short-and long-term effect. Legumes, on the other hand, seemed not to affect or even to increase damping-off as compared to continuously cultivated sugar beet. The influence on preceding crops on different soil types varied greatly. The inoculum density or potential of Pythium generally correlated poorly with damping-off of sugar beet. Nor did disease transformations cause any overall improvement of correlations.

After examination of the research carried out by other agencies, Saskatchewan Highways and Transportation (SHT) embarked on an initiative to adapt low tire pressure technologies to the province's needs and environment. The focus of the initiative was to explore several technical questions from SHT's perspective: (a) Can low tire pressures be used to increase truck weights from secondary to primary without increasing road maintenance costs on thin membrane surface roads? (b) What are the short- and long-term effects of tire heating under high-speed/high-deflection constant reduced pressure (CRP) operations in a Saskatchewan environment? (c) What effects do lower tire pressures have on vehicle stability at highway speeds? To date, significant opportunities have been noted on local hauls (less than 30 min loaded at highway speeds) for CRP operation and long primary highway hauls that begin or end in relatively short secondary highway sections that limit vehicle weight allowed for the whole trip for central tire inflation technology. The background and environment for the initiative and the investigations and demonstrations envisioned and undertaken are briefly outlined.

The influence of development and sex on pain perception has long been recognized but only recently has it become clear that this is due to specific differences in underlying pain neurobiology. This chapter summarizes the evidence for mechanistic differences in male and female pain biology and for functional changes in pain pathways through infancy, adolescence, and adulthood. It describes how both developmental age and sex determine peripheral nociception, spinal and brainstem processing, brain networks, and neuroimmune pathways in pain. Finally, the chapter discusses emerging evidence for interactions between sex and development and the importance of sex in the short- and long-term effects of early life pain.
