East Asian summer monsoon delivers large abundances of very-short-lived organic chlorine substances to the lower stratosphere.

Deep convection in the Asian summer monsoon is a significant transport process for lifting pollutants from the planetary boundary layer to the tropopause level. This process enables efficient injection into the stratosphere of reactive species such as chlorinated very-short-lived substances (Cl-VSLSs) that deplete ozone. Past studies of convective transport associated with the Asian summer monsoon have focused mostly on the south Asian summer monsoon.

Considering intentional stratospheric dehydration for climate benefits.

We introduce a climate intervention strategy focused on decreasing water vapor (WV) concentrations near the tropopause and in the stratosphere to increase outbound longwave radiation. The mechanism is the targeted injection of ice-nucleating particles (INP) in air supersaturated with respect to ice at high altitudes in the tropical entryway to the stratosphere. Ice formation in this region is a critical control of stratospheric WV.

Unexpectedly rapid aerosol formation in the Hunga Tonga plume.

The Hunga Tonga-Hunga Ha'apai (HT-HH) volcanic eruptions on January 13 and 15, 2022, produced a plume with the highest signal in stratospheric aerosol optical depth observed since the eruption of Mt. Pinatubo in 1991. Suites of balloon-borne instruments on a series of launches from Réunion Island intercepted the HT-HH plume between 7 and 10 d of the eruptions, yielding observations of the aerosol number and size distribution and sulfur dioxide (SO) and water vapor (HO) concentrations.

A Lightweight Remote Sensing Payload for Wildfire Detection and Fire Radiative Power Measurements.

Small uncrewed aerial systems (sUASs) have the potential to serve as ideal platforms for high spatial and temporal resolution wildfire measurements to complement aircraft and satellite observations, but typically have very limited payload capacity. Recognizing the need for improved data from wildfire management and smoke forecasting communities and the potential advantages of sUAS platforms, the Nighttime Fire Observations eXperiment (NightFOX) project was funded by the US National Oceanic and Atmospheric Administration (NOAA) to develop a suite of miniaturized, relatively low-cost scientific instruments for wildfire-related measurements that would satisfy the size, weight and power constraints of a sUAS payload. Here we report on a remote sensing system developed under the NightFOX project that consists of three optical instruments with five individual sensors for wildfire mapping and fire radiative power measurement and a GPS-aided inertial navigation system module for aircraft position and attitude determination.

Are Late Bloomers Real? Identification and Comparison of Late-Onset Offending Patterns from Ages 14-40.

Numerous studies have identified a late-onset pattern of offending, yet debate remains over whether this pattern is real or attributable to measurement error. The goal of the present study is to identify whether this late-onset trajectory exists. We used prospective longitudinal data from the Rochester Youth Development Study and group-based trajectory modeling to identify distinct developmental patterns in self-reported incidence of general delinquency from approximately ages 14 to age 31.

Intergenerational Continuity and Discontinuity in Substance Use: The Role of Concurrent Parental Marijuana Use.

Purpose: This study examines whether parental marijuana use that occurs during the life of a child impacts patterns of continuity and discontinuity in adolescent substance use among father-child dyads.

Methods: The study uses data from 263 father-child-mother triads involved in the Rochester Youth Development Study (RYDS) and the Rochester Intergenerational Study (RIGS). We use a dual trajectory model is used to examine the research questions.

Intergenerational Patterns in Offending: Lessons from the Rochester Intergenerational Study-ASC Division of Developmental and Life Course Criminology David P. Farrington Lecture, 2019.

Purpose: In recent years, criminology has seen an increase in the number of 3-generation, prospective studies of offending. The most fundamental question posed by these studies is whether, and to what extent, parental involvement in adolescent delinquency increases the risk of offending by their offspring. There are several important substantive and methodological challenges that need to be confronted in assessing the intergenerational effect including the examination of moderating influences that can change the level of intergenerational continuity and methodological issues as definitional elasticity-the impact on the level of intergenerational continuity that is likely to be observed based on a) how offending is defined and b) how the inherent heterogeneity in offending is taken into accounted.

How Early Is Too Early? Identification of Elevated, Persistent Problem Behavior in Childhood.

We inquire how early in childhood children most at risk for problematic patterns of internalizing and externalizing behaviors can be accurately classified. Yearly measures of anxiety/depressive symptoms and aggressive behaviors (ages 6-13; n = 334), respectively, are used to identify behavioral trajectories. We then assess the degree to which limited spans of yearly information allow for the correct classification into the elevated, persistent pattern of the problem behavior, identified theoretically and empirically as high-risk and most in need of intervention.

Provider Practice and Perceptions of Pediatric Obesity in Appalachian Kentucky.

Objectives: This study assessed providers' present practices and perceived needs in Appalachian Kentucky to identify the standard of care and implementation of expert recommendations for managing pediatric obesity.

Methods: Questionnaire data were gathered from 28 providers at a pediatric obesity continuing medical education workshop in eastern Kentucky. We assessed current practices, perceived barriers to treatment, and needed resources for managing pediatric obesity.

Black carbon lofts wildfire smoke high into the stratosphere to form a persistent plume.

In 2017, western Canadian wildfires injected smoke into the stratosphere that was detectable by satellites for more than 8 months. The smoke plume rose from 12 to 23 kilometers within 2 months owing to solar heating of black carbon, extending the lifetime and latitudinal spread. Comparisons of model simulations to the rate of observed lofting indicate that 2% of the smoke mass was black carbon.

Water Vapor, Clouds, and Saturation in the Tropical Tropopause Layer.

The goal of this investigation is to understand the mechanism behind the observed high relative humidity with respect to ice (RHi) in the tropical region between ~14 km (150 hPa) and the tropopause, often referred to as the tropical tropopause layer (TTL). As shown by satellite, aircraft and balloon observations, high (>80%) RHi regions are widespread within the TTL. Regions with the highest RHi are co-located with extensive cirrus.

The reproduction of child maltreatment: An examination of adolescent problem behavior, substance use, and precocious transitions in the link between victimization and perpetration.

Growing evidence suggests that maltreatment is reproduced across generations as victims of maltreatment are at an increased risk for maltreatment perpetration. Unfortunately, little information about mediating pathways exists to provide an explanation for why maltreatment begets maltreatment. We use the number of types of maltreatment experienced to predict later maltreatment perpetration and then examine two developmental pathways that may serve as bridges between maltreatment victimization and perpetration: adolescent problem behaviors and precocious transitions to adulthood.

Scaling-Up Evidence-Based Programs Using a Public Funding Stream: a Randomized Trial of Functional Family Therapy for Court-Involved Youth.

The Affordable Care Act expanded access to Medicaid programs and required them to provide essential health benefits, which can include prevention services. This study assesses the costs and benefits to using Medicaid funding to implement a well-known evidence-based program, Functional Family Therapy (FFT), with a sample of juvenile justice-involved youth. The study also provides a rigorous test of FFT accommodated for a contemporary urban population that is gang at risk or gang-involved.

Microphysical Properties of Tropical Tropopause Layer Cirrus.

Pervasive cirrus clouds in the tropical tropopause layer (TTL) play an important role in determining the composition of stratospheric air through dehydration of tropospheric air entering the stratosphere. This dehydration affects Earth's energy budget and climate, yet uncertainties remain regarding the microphysical processes that govern TTL cirrus. TTL cirrus were sampled with the NASA Global Hawk UAV for over 30 hr in the Western Pacific in 2014 during the Airborne Tropical TRopopause EXperiment.

Implementing Community Baby Showers to Address Infant Mortality in Oklahoma.

IMPORTANCE: Oklahoma has one of the highest rates of infant mortality and poor birth outcomes in the U.S., particularly among minority populations.

The Role of Sulfur Dioxide in Stratospheric Aerosol Formation Evaluated Using In-Situ Measurements in the Tropical Lower Stratosphere.

Stratospheric aerosols (SAs) are a variable component of the Earth's albedo that may be intentionally enhanced in the future to offset greenhouse gases (geoengineering). The role of tropospheric-sourced sulfur dioxide (SO) in maintaining background SAs has been debated for decades without in-situ measurements of SO at the tropical tropopause to inform this issue. Here we clarify the role of SO in maintaining SAs by using new in-situ SO measurements to evaluate climate models and satellite retrievals.

Definitional Elasticity in the Measurement of Intergenerational Continuity in Substance Use.

Increasingly, three generation studies have investigated intergenerational (IG) continuity and discontinuity in substance use and related problem behaviors. However, surprisingly little attention has been paid to the conceptual definition of continuity or to different types of discontinuity (resilience and escalation) or to measurement sensitivity, which affects not only the magnitudes of observed continuity but also factors that correlate with this linkage. This study uses longitudinal data on 427 parent-child dyads from the Rochester IG Study to study continuity and discontinuity in substance use over ages 14-18.

Efficient transport of tropospheric aerosol into the stratosphere via the Asian summer monsoon anticyclone.

An enhanced aerosol layer near the tropopause over Asia during the June-September period of the Asian summer monsoon (ASM) was recently identified using satellite observations. Its sources and climate impact are presently not well-characterized. To improve understanding of this phenomenon, we made in situ aerosol measurements during summer 2015 from Kunming, China, then followed with a modeling study to assess the global significance.

Physical Processes Controlling the Vertical and Longitudinal Distributions of Relative Humidity in the Tropical Tropopause Layer Over the Pacific.

The vertical distribution of relative humidity with respect to ice (RHI) in the Boreal wintertime Tropical Tropopause Layer (TTL, ≃14-18 km) over the Pacific is examined with the extensive dataset of measurements from the NASA Airborne Tropical TRopopause EXperiment (ATTREX). Multiple deployments of the Global Hawk during ATTREX provided hundreds of vertical profiles spanning the longitudinal extent of the Pacific with accurate measurements of temperature, pressure, water vapor concentration, ozone concentration, and cloud properties. We also compare the measured RHI distributions with results from a transport and microphysical model driven by meteorological analysis fields.

Intergenerational consequences of adolescent substance use: Patterns of homotypic and heterotypic continuity.

Does substance use run in families? In this article, we examine both homotypic continuity in substance use-the impact of a parent's adolescent substance use on their child's adolescent substance use-and heterotypic continuity-the impact of a parent's adolescent substance use on their child's involvement in other adolescent problem behaviors. The analysis is based on data from the Rochester Youth Development Study (Thornberry, Lizotte, Krohn, Smith, & Porter, 2003) and its intergenerational component, the Rochester Intergenerational Study (Thornberry, 2009). The initial study began with a representative sample of 7th and 8th grade students followed until Age 31, and the intergenerational study is currently following their oldest biological child from childhood through adolescence.

Explaining Adolescent Drug Use in Adjacent Generations: Testing the Generality of Theoretical Explanations.

We tested the assumption that theories of drug use are able to account for behavior across varying contexts and populations by examining whether control, learning, and elaborated theories provide similar explanations for adolescent drug use in adjacent generations. We used data from the Rochester Youth Development Study and Rochester Intergenerational Study which followed a sample of adolescents starting at age 14 and their oldest biological child. Cross-generational analysis between theoretical variables measured at age 14 and drug use measured at approximately ages 15 and 16 were used.

The impact of adolescent risk behavior on partner relationships.

Prior literature suggests that involvement in adolescent risk behaviors will have short- and long-term consequences that disrupt the orderly flow of later development, including impacts on patterns of partner relationships. In this study, we explore how adolescent involvement in delinquency, drug use, and sexual behavior at an early age affects the likelihood and timing of both marriage and cohabitation using a sample from the Rochester Youth Development Study. We also examine the direct effects of dropping out of high school, teenage parenthood, and financial stress during emerging adulthood as well as their potential role as mediators of the relationships between adolescent risk behaviors and partnering for both males and females.
