The purpose of this study is to explore the differential impact of various environmental and organizational factors on levels of school misconduct. Although we have a general understanding of this relationship, little effort has been made to determine whether the effects are influenced by urbanicity. The current study utilizes data from the 2007-2008 School Survey on Crime and Safety to address this gap in the literature by utilizing a series of negative binomial regression models that seek to determine differences between predictive factors in urban and rural settings. Results indicate that disorganization has a similar effect within urban and rural schools, increasing counts of misconduct. On the contrary, results also suggest that urban and rural schools, which are already characterized by elevated rates of misconduct, tend to implement different types of security. This study is concluded by discussing methodological limitations, various theoretical and policy implications, and directions for future research.

Heatwave studies typically estimate heat-related mortality and morbidity risks at the city level; few have addressed the heterogeneous risks by socioeconomic status (SES) and location within a city. This study aimed to examine the impacts of heatwaves on mortality outcomes in Memphis, Tennessee, a Mid-South metropolitan area top-ranked in morbidity and poverty rates, and to investigate the effects of SES and urbanicity. Mortality data were retrieved from the death records in 2008–2017, and temperature data from the Applied Climate Information System. Heatwave days were defined based on four temperature metrics. Heatwave effects on daily total-cause, cardiovascular, and respiratory mortality were evaluated using Poisson regression, accounting for temporal trends, sociodemographic factors, urbanicity, and air pollution. We found higher cardiovascular mortality risk (cumulative RR (relative risk) = 1.25, 95% CI (confidence interval): 1.01–1.55) in heatwave days defined as those with maximum daily temperature >95th percentile for more than two consecutive days. The effects of heatwaves on mortality did not differ by SES, race, or urbanicity. The findings of this study provided evidence to support future heatwave planning and studies of heatwave and health impacts at a coarser geographic resolution.

The purpose of this study was to provide a descriptive analysis comparing highly qualified and non-highly qualified special education teachers in the 2011-12 Schools and Staffing Survey. It examined how the qualifications of special education teachers varied among K-12 public schools according to the urbanicity of the school and the proportion of students in poverty within a school. Variables included those related to teacher qualifications, demographic characteristics, and school characteristics. The findings demonstrated that there were differences in the demographic characteristics of highly qualified and non-highly qualified special education teachers. There were no statistically significant differences found for urbanicity alone. There were statistically significant differences found for poverty levels. Statistically significant differences were also found for both highly qualified and non-highly qualified special education teachers when poverty quartiles were analyzed by urbanity locales. The findings emphasize the need to provide targeted interventions to promote, retain, and supply all schools with qualified special education teachers. The findings also indicate there is an unequal distribution of highly qualified special education teachers within identified poverty levels and urbanicity. / PHD

Growing up in an urban area has been shown to be associated with an increased risk of psychotic disorder in later life. While it is commonly held that a only a tiny fraction of exposed individuals will develop schizophrenia, recent evidence suggests that expression of psychosis in exposed individuals may be much more common, albeit at attenuated levels. Findings are based on a population sample of 2548 adolescents and young adults aged originally 14–24 years, and followed up over almost 5 years up to ages 17–28 years. Trained psychologists assessed all these subjects with the core psychosis sections on delusions and hallucinations of the Munich-Composite International Diagnostic Interview. Growing up in an urban area was associated with an increased risk of expression of psychosis in the adolescents and young adults (adjusted OR 1.31, 95% CI 1.03–1.66). The proxy environmental risk factor that urbanicity represents may shift a relatively large section of the adolescent population along a continuum of expression of psychosis. Other causal influences may be required to make the transition to schizophrenia in adult life.

Introduction: Adolescents in the United States use alcohol more than any other substance, including tobacco and marijuana. Continuing alcohol misuse has numerous adverse health effects and is linked to liver disease, cancer, cardiovascular disease and neurological damage. Furthermore, alcohol consumption is a significant risk factor for unsafe sexual behaviors, unintentional injuries, physical and sexual assaults, various types of illegal activities, and suicide (USDHHS, 2007). Aim: The purpose of this study is to compare the individual social indicators from 4 categories that have been identified within the literature as being particularly associated with alcohol consumption in general, and underage alcohol consumption in particular. The categories used were: drinking consequences, urbanicity, poverty, and alcohol outlet density. The social indicators in these categories will be compared in the 10 most-at-risk counties (MAR) and the 10 least-at-risk counties (LAR), and the 20 MAR counties and the 20 LAR counties, as they relate to underage alcohol consumption. Methods: The counties were identified in and data was obtained from Governor’s Cooperative Agreement State Incentive Planning and Development Grant: Social Indicator Study to Assess Substance Use Prevention Needs at the State and County Levels in Georgia. An independent 2-tailed t-test was conducted to compare the means of groups in both the 10 MAR/LAR counties and the 20 MAR/LAR counties. Results: Significant differences were observed in all of the individual indicators in the poverty and alcohol outlet density categories for both the 10 MAR/LAR counties and the 20 MAR/LAR counties. Discussion: There needs to be a more accurate, specific and efficient methods of data surveillance concerning underage drinking behavior. Further research should focus on urbanicity, poverty, and alcohol outlet density as they relate to underage alcohol consumption. There were differences observed between the MAR and LAR counties in all of the poverty alcohol outlet density indicators, and researchers and policy makers should pay special attention to these two areas when designing further research and prevention policies.

Background. Evidence suggests that in affective, non-psychotic disorders: (i) environmental exposures increase risk of subthreshold psychotic experiences (PEs) and strengthen connectivity between domains of affective and subthreshold psychotic psychopathology; and (ii) PEs are a marker of illness severity. Method. In 3021 adolescents from the Early Developmental Stages of Psychopathology cohort, we tested whether the association between PEs and presence of DSM-IV mood disorder (MD)/obsessive–compulsive disorder (OCD) would be moderated by risk factors for psychosis (cannabis use, childhood trauma and urbanicity), using the interaction contrast ratio (ICR) method. Furthermore, we analysed whether the interaction between environment and PEs was mediated by non-psychotic psychopathology. Results. The association between PEs and MD/OCD was moderated by urbanicity (ICR = 2.46, p = 0.005), cannabis use (ICR = 3.76, p = 0.010) and, suggestively, trauma (ICR = 1.91, p = 0.063). Exposure to more than one environmental risk factor increased the likelihood of co-expression of PEs in a dose–response fashion. Moderating effects of environmental exposures were largely mediated by the severity of general non-psychotic psychopathology (percentage explained 56–68%, all p < 0.001). Within individuals with MD/OCD, the association between PEs and help-seeking behaviour, as an index of severity, was moderated by trauma (ICR = 1.87, p = 0.009) and urbanicity (ICR = 1.48, p = 0.005), but not by cannabis use. Conclusions. In non-psychotic disorder, environmental factors increase the likelihood of psychosis admixture and helpseeking behaviour through an increase in general psychopathology. The findings are compatible with a relational model of psychopathology in which more severe clinical states are the result of environment-induced disturbances spreading through a psychopathology network.
