This study aimed to examine changes in depression and anxiety symptoms from before to during the first 6 months of the COVID-19 pandemic in a sample of 1,339 adolescents (9–18 years old, 59% female) from three countries. We also examined if age, race/ethnicity, disease burden, or strictness of government restrictions moderated change in symptoms. Data from 12 longitudinal studies (10 U.S., 1 Netherlands, 1 Peru) were combined. Linear mixed effect models showed that depression, but not anxiety, symptoms increased significantly (median increase = 28%). The most negative mental health impacts were reported by multiracial adolescents and those under ‘lockdown’ restrictions. Policy makers need to consider these impacts by investing in ways to support adolescents’ mental health during the pandemic. 相似文献

Although widely available, little is known about the effectiveness of youth cessation treatments delivered in real-world settings. The authors recruited a nonprobability sample of 41 community-based group-format programs that treated at least 15 youth per year and included evidence-based treatment components. Data collection included longitudinal surveys of youth participants (n = 878); posttreatment surveys of program leaders (n = 77); and one-time surveys of organizational leaders (n = 64)and community leaders in education, health, and juvenile justice (n = 94). Information about smoking-related ordinances was collected at the state and local levels. The framework, evaluation design, and implementation strategies described in this article provide a template for large-scale real-world program evaluations. 相似文献

Current guidelines for school-based substance use prevention suggest that prevention efforts should begin in elementary grades, before students begin using substances. Previous research suggests, however, that the use of evidence-based curricula in these grades may be low. Using a 2005 survey of public school districts in the United States that include elementary grades (n = 1563), we assessed the prevalence of elementary curricula use, particularly those designated as evidence-based. We found that although 72% of districts administer a substance use prevention curriculum to their elementary students, only about 35% are using one that is evidence-based and only about 14% are using an evidence-based curriculum more so than any other prevention curriculum. We present prevalence estimates for specific evidence-based curricula and conclude by discussing possible reasons for and implications of our findings. 相似文献

This study examined desegregated classrooms with an emphasis on how students' perceptions of Allport's (1954) contact dimensions influence the frequency and effectiveness of their coping strategies for interracial stress, their self-esteem, and their self-reported academic performance. Fourth, fifth, and sixth graders from two ethnically diverse middle schools in Los Angeles, California, participated. Results indicated that students' perceptions of a more positive interracial classroom climate were associated with less frequent and more effective coping strategies, specifically as related to the frequency and effectiveness of positive/approach coping strategies. Positive classroom climate also was related to higher self-esteem and better academic performance. This research highlights the importance of the presence of contact criteria when desegregation is to be a positive experience both academically and socially and of the integration of coping strategies as a means of reducing interracial stress. 相似文献

Outcomes for youth from foster care have been found to be poor. The education and employment outcomes of youth and alumni of foster care served by transition programmes located in five major US cities were examined. Data were collected by case managers and reported to evaluators quarterly on 1058 youth from foster care for over 2 years. Job preparation, transportation, child care, education support services and life skills were the most common services provided to youth. During the 2‐year study period, 35% of participants obtained employment, 23% obtained a General Education Development or diploma, and 17% enrolled in post‐secondary education. It was found that the longer the youth were enrolled, the more education and employment outcomes they achieved. Further, job preparation and income support services were associated significantly with achieving any positive education or employment outcome. Results indicated that certain services provided over an extended period of time can improve outcomes for youth placed in foster care. For youth to achieve positive outcomes as they transition to adulthood, additional services are necessary. Other implications are discussed. 相似文献

Variation in densities of native and exotic urban-adapted birds across suburban habitats may reveal levels of adaptation that predict vulnerability to habitat modification over time. We investigated the densities of the eight most common exotic and native birds in a southern hemisphere city across suburbs of varying housing density, vegetative cover and garden vegetation characteristics to determine whether avian population densities are maintained across variations in habitat structure that mirror current temporal trends in land use and landscaping/gardening preferences. We also tested whether densities of birds in residential areas bordering undeveloped patches were higher due to spill-over from patches. Densities of all four native species were highest in undeveloped patches and these species were largely absent from high density housing areas. While densities of two exotic species (blackbird, song thrush) were slightly higher in suburbs with greater vegetation complexity, they were still present in higher density housing suburbs in significant numbers. Common starlings were similarly abundant across all residential habitats and house sparrow density increased in higher density housing areas. Blackbirds appeared least vulnerable to housing densification and landscaping and gardening trends because they were abundant across all habitats, including undeveloped patches. Densities of native birds were higher in residential areas bordering undeveloped patches indicating spill-over was occurring and emphasising the role that patches could play in boosting city-wide native bird abundances. Native birds are vulnerable to reductions in garden size and vegetation complexity that should have little or positive effects on populations of common exotic species. 相似文献

The research considers the balance of intellectual versus entertainment-oriented individuals appearing as interview guests on political satire programs. Specifically, the analysis employs semi-supervised learning to categorize the occupations of individuals appearing on The Daily Show and The Colbert Report between 2003 and 2014 (N = 3,507). The results confirm that satire programs have become an important outlet for politicians and journalists looking to connect with a younger audience. More often than not, these guest appearances privilege a newsworthy and intellectually oriented discussion of contemporary issues and ideas as opposed to the promotion of entertainment content. Important to note, the data set represents the largest body of political satire content analyzed to date and the results confirm the value of applying automated and semi-supervised learning coding within communication research. We conclude by discussing the methodological contributions of our coding process, future directions for political comedy research, and the scalable potential of automated coding efforts. 相似文献

We study the effects of using a partial backordering approach to controlling inventories under deterministic and stochastic demands, respectively. With a deterministic demand, our model is built with the objective of minimizing the total cost of ordering, holding, backordering and lost sales. The conditions for the partial backordering policy to be feasible are identified and a pair-wise comparison among the no-backordering, complete backordering, and partial backordering doctrines is conducted. In the stochastic case, we focus on a make-to-stock system with a Poisson demand and exponential production time, which allows us to establish a queuing model to examine the cost-effectiveness of using partial backorders. The conditions under which the partial backordering policy outperforms the complete backordering policy are identified. 相似文献
