The Immediate Impact of COVID-19 on Law Enforcement in the United States
© 2020, Southern Criminal Justice Association. During pandemics, like COVID-19, law enforcement agencies are responsible for working with government and public health officials to contain spread, serve the local community, and maintain public order. Given the person-to-person spread of COVID-19 through respiratory droplets, law enforcement officers are also at a heightened risk of exposure due to their close contact with members of the public. To protect officers, the Centers for Disease Control and Prevention (CDC) and other agencies have made numerous recommendations for law enforcement agencies to protect officers and the public. Departments around the country have responded to the pandemic in various ways, such as reassigning personnel to high-traffic areas, suspending training, roll calls, and community outreach initiatives, only issuing citations for low-level crimes, implementing safety precautions for officers, and limiting access to department facilities. The COVID-19 pandemic also has exposed some key obstacles for law enforcement, related to communication, resource management, the enforcement of public health restrictions, and changes to crime and service patterns. Based on these early/initial responses and obstacles during the COVID-19 outbreak, the current paper highlights directions for future responses to pandemics to ensure the safety and security of police officers and the communities they serve
Racial Threat, Urban Conditions and Police Use of Force: Assessing the Direct and Indirect Linkages Across Multiple Urban Areas
Traditionally explanations of police use of force have relied on a racial threat perspective. Tests of this perspective, however, typically offer a single indicator of threat (the relative size of the black population) and fail to adequately take into account the complex relationship between racial threat and police use of force. Drawing on racial threat, social disorganization, and police use of force literature, this study hypothesizes that macro-level patterns in police use of force are embedded in the racial and structural composition of cities and the organizational climate of local politics and police departments. The present study examines these relationships using official police use of force data collected in 73 large U.S. cities. Structural equation analyses suggest that structural indicators associated with racial threat and social disorganization/disadvantage impact police use of force indirectly through the influence of police organizational factors. On the other hand, the political climate and the level of social disorganization in urban areas have a direct bearing on the rates of police use of force. The implications of these findings for research and theory on police use of force are discussed
Characteristics of adults involved in alcohol-related intimate partner violence: results from a nationally representative sample
Background
More than 12 million women and men are victims of partner violence each year. Although the health outcomes of partner violence have been well documented, we know very little about specific event-level characteristics that may provide implications for prevention and intervention of partner violence situations. Therefore, the purpose of this study is to evaluate substance abuse and dependence as risk factors for event-level alcohol-related intimate partner violence (IPV). Methods
Data were derived from Wave II of the National Epidemiological Survey on Alcohol and Related Conditions (2004–2005). Eligible participants (N = 2,255) reported IPV the year before the survey. Negative binomial and ordinal regression methods were used to assess risk factors for alcohol use during IPV. Results
Respondent PTSD was the only mental health diagnosis related to alcohol use during IPV (OR = 1.45). Marijuana use was related to respondents’ use of alcohol during IPV (OR = 2.68). Respondents’ meeting the criteria for alcohol abuse/dependence was strongly associated with respondent drinking (OR = 10.74) and partner drinking (OR = 2.89) during IPV. Conclusion
Results indicate that PTSD, marijuana use disorders, alcohol abuse and dependence are associated with more frequent alcohol use during IPV. In addition, it is important to consider that the patient who presents in emergency settings (e.g., hospitals or urgent care facilities) may not be immediately identifiable as the victim or the perpetrator of partner violence. Therefore, screening and intervention programs should probe to further assess the event-level characteristics of partner violence situations to ensure the correct service referrals are made to prevent partner violence
Dating and intimate partner violence among young persons ages 15-30 : evidence from a systematic review
While there has been much empirical research on adult dating violence, only recently has research began to also focus on young adult dating violence in general and teen dating violence specifically. With recognition of the growing research and media attention toward youth and young adult dating violence, the current study provides a systematic review of the extant literature devoted toward examinations of dating/intimate partner violence among individuals aged 15 to 30 and, more narrowly, on the prior research that has tested the effectiveness of dating/intimate partner violence interventions with this age group. Results from a comprehensive literature search of a number of existing databases revealed 169 studies that met the inclusion criteria, and 42 of these 169 studies were also characterized as intervention studies. Descriptive results are discussed for the 169 studies overall, and for the 42 intervention studies in particular in greater detail. Evidence gleaned from this systematic review revealed a number of similarities and differences between the studies in general, but also pointed toward the potential effectiveness of interventions to prevent the occurrence and re-occurrence of dating/intimate partner violence. Study limitations and directions for future research are also discussed.

Community-Led Response to Address Economic Vulnerability due to COVID-19 with, for, and by Transgender Women of Color: A Qualitative Pilot Evaluation
PURPOSE: Intersectional stigma fuels inequities among transgender women of color, which have been exacerbated by coronavirus disease 2019 (COVID-19). This study evaluated a community-led emergency assistance program for transgender women of color.
METHODS: We conducted a pilot program evaluation (n=8).
RESULTS: Retention was 87.5% over the follow-up. Funds were primarily used for bills, food, and housing. Requesting and receiving funds was described as somewhat to extremely easy. Participants identified the need for economic empowerment components in future programming, specifically gender affirmation, skill-building for education and employment, and entrepreneurial opportunities.
CONCLUSION: Findings highlight the need to invest in community-led strategies to address inequities experienced by transgender women of color
Effects of early family / parenting programs on antisocial behavior and delinquency
Early family/parent training programs are intended to serve many purposes, one
of them being the prevention of child behavior problems including antisocial behavior
and delinquency. While early family/parent training may not often be implemented with
the expressed aim of preventing antisocial behavior, delinquency, and crime – sometimes
these programs are aimed at more general, non-crime outcomes – its relevance to the
prevention of crime has been suggested in developmentally-based criminological and
psychological literatures.
The main objective of this review is to assess the available research evidence on
the effects of early family/parent training on child behavior problems including antisocial
behavior and delinquency. In addition to assessing the overall impact of early
family/parent training, this review will also investigate, to the extent possible, in which
settings and under what conditions it is most effective
Association of Accelerometry-Measured Physical Activity and Cardiovascular Events in Mobility-Limited Older Adults: The LIFE (Lifestyle Interventions and Independence for Elders) Study.
BACKGROUND:Data are sparse regarding the value of physical activity (PA) surveillance among older adults-particularly among those with mobility limitations. The objective of this study was to examine longitudinal associations between objectively measured daily PA and the incidence of cardiovascular events among older adults in the LIFE (Lifestyle Interventions and Independence for Elders) study. METHODS AND RESULTS:Cardiovascular events were adjudicated based on medical records review, and cardiovascular risk factors were controlled for in the analysis. Home-based activity data were collected by hip-worn accelerometers at baseline and at 6, 12, and 24 months postrandomization to either a physical activity or health education intervention. LIFE study participants (n=1590; age 78.9±5.2 [SD] years; 67.2% women) at baseline had an 11% lower incidence of experiencing a subsequent cardiovascular event per 500 steps taken per day based on activity data (hazard ratio, 0.89; 95% confidence interval, 0.84-0.96; P=0.001). At baseline, every 30 minutes spent performing activities ≥500 counts per minute (hazard ratio, 0.75; confidence interval, 0.65-0.89 [P=0.001]) were also associated with a lower incidence of cardiovascular events. Throughout follow-up (6, 12, and 24 months), both the number of steps per day (per 500 steps; hazard ratio, 0.90, confidence interval, 0.85-0.96 [P=0.001]) and duration of activity ≥500 counts per minute (per 30 minutes; hazard ratio, 0.76; confidence interval, 0.63-0.90 [P=0.002]) were significantly associated with lower cardiovascular event rates. CONCLUSIONS:Objective measurements of physical activity via accelerometry were associated with cardiovascular events among older adults with limited mobility (summary score >10 on the Short Physical Performance Battery) both using baseline and longitudinal data.

Stellar Spectroscopy in the Near-infrared with a Laser Frequency Comb
The discovery and characterization of exoplanets around nearby stars is
driven by profound scientific questions about the uniqueness of Earth and our
Solar System, and the conditions under which life could exist elsewhere in our
Galaxy. Doppler spectroscopy, or the radial velocity (RV) technique, has been
used extensively to identify hundreds of exoplanets, but with notable
challenges in detecting terrestrial mass planets orbiting within habitable
zones. We describe infrared RV spectroscopy at the 10 m Hobby-Eberly telescope
that leverages a 30 GHz electro-optic laser frequency comb with nanophotonic
supercontinuum to calibrate the Habitable Zone Planet Finder spectrograph.
Demonstrated instrument precision <10 cm/s and stellar RVs approaching 1 m/s
open the path to discovery and confirmation of habitable zone planets around
M-dwarfs, the most ubiquitous type of stars in our Galaxy
Identifying invasive species threats, pathways, and impacts to improve biosecurity
Managing invasive species with prevention and early-detection strategies can avert severe ecological and economic impacts. Horizon scanning, an evidence-based process combining risk screening and consensus building to identify threats, has become a valuable tool for prioritizing invasive species management and prevention. We assembled a working group of experts from academic, government, and nonprofit agencies and organizations, and conducted a multi-taxa horizon scan for Florida, USA, the first of its kind in North America. Our primary objectives were to identify high-risk species and their introduction pathways, to detail the magnitude and mechanism of potential impacts, and, more broadly, to demonstrate the utility of horizon scanning. As a means to facilitate future horizon scans, we document the process used to generate the list of taxa for screening. We evaluated 460 taxa for their potential to arrive, establish, and cause negative ecological and socioeconomic impacts, and identified 40 potential invaders, including alewife, zebra mussel, crab-eating macaque, and red swamp crayfish. Vertebrates and aquatic invertebrates posed the greatest invasion threat, over half of the high-risk taxa were omnivores, and there was high confidence in the scoring of high-risk taxa. Common arrival pathways were ballast water, biofouling of vessels, and escape from the pet/aquarium/horticulture trade. Competition, predation, and damage to agriculture/forestry/aquaculture were common impact mechanisms. We recommend full risk analysis for the high-risk taxa; increased surveillance at Florida's ports, state borders, and high-risk pathways; and periodic review and revision of the list. Few horizon scans detail the comprehensive methodology (including list-building), certainty estimates for all scoring categories and the final score, detailed pathways, and the magnitude and mechanism of impact. Providing this information can further inform prevention efforts and can be efficiently replicated in other regions. Moreover, harmonizing methodology can facilitate data sharing and enhance interpretation of results for stakeholders and the general public.</p
