Suicide Risk in Emerging Adulthood: Associations with Screen Time over 10 years

Journal of Youth and Adolescence - Suicide rates have increased over the past decade, and screen media (and social media in particular) are often blamed for this marked increase. However, there is...     

The Death of Freddie Gray and Its Impact on Homicides in Baltimore and Maryland

This study evaluated the impact that Freddie Gray’s death on April, 19, 2015, had on homicides within Baltimore, Prince George’s County, and the rest of Maryland. The numbers of these deaths were compared in the 2 years prior and after his death. The average number of homicide per month in Baltimore and Prince George’s County, but not the rest of Maryland, showed a statistically significant increase in the 2 years after his death, with a sudden spike in homicides in Baltimore immediately following his death. Spatial density (“heat”) maps of homicides showed an increase in clustering of deaths after Freddie Gray’s demise in portions of Baltimore, particularly near his arrest site. Hot spot maps showed a massive expansion of statistically significant clusters of homicides in areas of West and East Baltimore after his death. An emerging hot spot analysis revealed consecutive hot spots in large areas of West Baltimore with new hot spots prominent along the southern edge of this area. A review of the history of Baltimore, as well as discussions with Baltimore homicide detectives, revealed that prior socioeconomic and political trends likely primed Baltimore for the protests and violence that occurred after Freddie Gray’s death. It is probable that a perceived “overcharging” of officers involved in his death by the State’s Attorney resulted in a “pullback” from policing that directly led to increased homicides in Baltimore.     

Abusive Pediatric Thoracolumbar Fracture Due to Forced Hyperextension: Case Report,Biomechanical Considerations,and Review of the Literature

Pediatric thoracolumbar fractures are rare due to the physiological differences which afford greater resilience to the immature spine. Most pediatric thoracolumbar fractures occur as the result of high energy trauma, such as motor vehicle accidents, and modes of reasonable accidental injuries are limited by age and developmental capabilities of the child. These fractures can occur as the result of inflicted blunt force trauma and child abuse, and in most cases, the mechanism of injury to the spine is not known. We report the death of a 29-month-old man due to blunt force trauma to the back and forced hyperextension of the thoracolumbar spine causing fracture of the fourth lumbar (L4) vertebral body. A complete forensic examination revealed a previous healing fracture of the anterior aspect of the L4 vertebral body, with acute disruption of the anterior longitudinal ligament overlying the fracture site, complete fracture of the vertebral body, and fatal retroperitoneal hemorrhage. We present a review of the biomechanical considerations of the pediatric spine, a survey of pediatric spinal fractures, and a review of the literature on pediatric abusive thoracolumbar fractures. In this case, there was never a provided explanation for how the injury occurred; however, understanding the biomechanics of the pediatric spine allowed for the determination of the mechanism, force required to produce this specific pattern of abusive spinal injury, and the manner of death.     

Treatment format and external validity in international relations experiments

Political scientists use short vignettes or mock news stories to embed treatments in experimental survey designs. We investigate whether the choice of format entails a trade off between internal and external validity. On the one hand, short vignettes may improve internal validity by isolating key variables without overloading respondents with information, thereby mitigating satisficing and improving data quality. On the other hand, mock news stories may improve external validity by approximating the circumstances under which individuals consume political information, which may enhance the credibility of the information. We find no evidence, however, that short vignettes mitigate satisficing more than mock news stories. Nor do we find that mock news stories enhance individual perceptions of the credibility of the information. Instead, we find that short vignettes are susceptible to confounding, which mock news story mitigate. These findings have important implications for debates about the use of survey experiments in political science.

Situating tenure,capital and finance in farmland relations: implications for stewardship and agroecological health in Ontario,Canada

Farmers in Canada are older and more capitalized than ever before. Meanwhile, farmland values continue to rise. These forces together are generating unprecedented shifts in farmland relations, marked by increasing reliance on rental tenure and the rise of hybrid owner–renter consolidating farmers. This paper explores these dynamics in Ontario and asks how they are impacting on-farm agroecological stewardship. To do so, we begin with a review of the land and property relations literature as well as farmland and agricultural change in Ontario. We then briefly review agroecological issues and concepts that are important for linking on-farm agroecological health to aformentioned farmland and agricultural changes. From here, we use survey, interview and soil sample data collected from grain farmers across Ontario to elucidate relatively new shifts in land tenure and use dynamics. We argue that this complex set of forces is interacting to produce an appealing set of conditions for financial investors, while restricting access to farmland for less-capitalized farmers. We then show how these shifts are divesting capital and attention from agroecological health. We conclude with a reflection on how the state has been mediating and contributing to these dynamics, and urgently call for land policy that prioritizes social and ecological principals.     

Post-Soviet Civil Society Development in the Russian Federation: The Impact of the NGO Law

The passing of the Russian NGO Law in mid-2006 set clear parameters for Russian NGO activity and civil society development. In this paper we assess the impact of the NGO Law on both NGOs and Russian civil society. Our findings illustrate that the NGO Law has led to a reduction in NGO activity and curtailment of civil society development. We conclude that Russian civil society appears to be dominated by groups funded and thus controlled by the state. This has implications for Russia's on-going democratic development.     

‘Una Esclavitud Simulada’: Debt peonage in the state of Chiapas,Mexico, 1876–1911 1

This article examines debt peonage in the state of Chiapas in southern Mexico during the regime of Porfirio Díaz (1876–1911). It argues that debt peonage in Chiapas was a coercive institution, which served to cheapen the price of labour in the growing agricultural export sector. Thus, rather than a ‘feudal relic’ incompatible with the logic of capitalist efficiency, the expansion and intensification of debt peonage during this time was consistent with the political economy of capitalist modernization in Mexico prior to the revolution of 1910–20.
