Reaching and engaging people: Analyzing tweeting practices of large U.S. police departments pre- and post- the killing of George Floyd.

Finding ways to improve police legitimacy and police-community relations has for long been an important social issue in the United States. It becomes particularly urgent following the murder of George Floyd on May 25th, 2020. An emerging area that holds potential in remediating police-community relations pertains to the use of social media by police. Yet, this body of research stays highly exploratory (e.g., case studies based on a small sample of agencies) and different viewpoints exist regarding the objectives of police social media usage. The current study identified 115 large police departments in the U.S. and collected their tweets over a 4-month period between 4/1/2020 and 7/31/2020. We investigated how police agencies (both individually and as an aggregate) leveraged social media to respond to the nationwide protests directed at the police and community reactions to such responses. We found that police agencies tweeted more frequently in the immediate aftermath of the murder and posted an increased number of civil-unrest related tweets. The public showed a greater interest in engaging with law enforcement agencies (i.e., average favorite and retweet counts) following the murder. A great variability emerged across agencies in their responses on social media, suggesting that examining only a handful of agencies or a particular dimension of social media usage would limit our understanding of police behaviors and citizen interactions on social media. In conclusion, we suggested a few avenues for future research (and practices) on responsible and effective use of social media by police, while pointing out the challenges associated with such inquiries.

An Exploration of Narcan as a Harm Reduction Strategy and User's Attitudes toward Law Enforcement Involvement in Overdose Cases.

The street homeless, those who spend their nights either in shelters or unofficial camps, whether in tents on a street or in society's hidden spaces such as beneath an overpass, face multiple challenges beyond finding a safe place to sleep. Of further concern is how official actions can worsen these situations, through day-to-day activities or planned intervention strategies. In this paper we explore how a planned intervention may be negatively perceived-even as a form of "structural violence"-and may prevent Narcan (naloxone) use to stop an overdose related death in the Skid Row of Los Angeles. Data for this study consisted of a combination of Spatial Video Geonarratives (SVGs) and 325 incident reports from the Homeless Health Care Los Angeles Center for Harm Reduction (HHCLA-HRC) between November 2014 and December 2015. Chi-square and simple logistic regression models were used to examine the association between fear-of-arrest and other covariates of interest. Mapping results are presented with different sets of shapefiles created for (1) all Narcan uses, (2) all homeless, (3) all homeless with a worry about being arrested, (4) all Narcan uses where an ambulance attended, (5) and the same as 4 but also with police attendance. In the multivariable model, the estimated adjusted odds of fear-of-arrest is over three times higher among Narcan users ages 30-39 when compared to users under the age of 30. Analyzing the association of calling 9-1-1 on Narcan user demographics, socio-contextual characteristics, and overdose victim demographics, the crude estimated probability of calling 9-1-1 for Narcan users aged 50 and older is nearly three times higher when compared to Narcan users aged 19-29. Conclusion: Results suggest that the fear-of-arrest and calling 9-1-1 during an overdose is still a concern among Narcan users despite protective legislation and access to harm reduction resources.

Impacts of California Proposition 47 on crime in Santa Monica, California.

We examine patterns of reported crime in Santa Monica, California before and after the passage of Proposition 47, a 2014 initiative that reclassified some non-violent felonies as misdemeanors. We also investigate impacts of the opening of four new light rail stations in 2016 and of increased community-based policing starting in late 2018. Our statistical analyses of reclassified crimes-larceny, fraud, possession of narcotics, forgery, receiving/possessing stolen property-and non-reclassified ones are based on publicly available reported crime data from 2006 to 2019. These analyses examine reported crime at various levels: city-wide, within eight neighborhoods, and within a 450-meter radius of the new transit stations. Monthly reported reclassified crimes increased city-wide by approximately 15% after enactment of Proposition 47, with a significant drop observed in late 2018. Downtown exhibited the largest overall surge. Reported non-reclassified crimes fell overall by approximately 9%. Areas surrounding two new train stations, including Downtown, saw significant increases in reported crime after train service began. While reported reclassified crimes increased after passage of Proposition 47, non-reclassified crimes, for the most part, decreased or stayed constant, suggesting that Proposition 47 may have impacted reported crime in Santa Monica. Reported crimes decreased in late 2018 concurrent with the adoption of new community-based policing measures. Follow-up studies needed to confirm long-term trends may be challenging due to the COVID-19 pandemic that drastically changed societal conditions. While our research detects changes in reported crime, it does not provide causative explanations. Our work, along with other considerations relevant to public utility, respect for human rights, and existence of socioeconomic disparities, may be useful to law enforcement and policymakers to assess the overall effect of Proposition 47.

Promoting Children's Mental, Emotional, and Behavioral (MEB) Health in All Public Systems, Post-COVID-19.

The COVID-19 pandemic exacerbates the mental, emotional, and behavioral (MEB) health problems of children and adolescents in the United States (U.S.). A collective and coordinated national economic and social reconstruction effort aimed at shoring up services to promote children's MEB, like the Marshall Plan that helped rebuild Europe post-World War II, has been proposed to buttress against the expected retrenchment. The plan prioritizes children's well-being as a social objective. We propose strategically reconstructing the public safety-net systems serving youth, including early education, maternal and child health, child welfare, corrections, and mental health. That plan called for a concentrated focus on coalition-building and contracting by state mental health systems to establish a foundation for an improved health system. This paper offers a complementary set of suggestions for the four non-mental health systems mentioned above by recommending actionable steps based on scientific evidence to support improved services for children at risk for MEB problems. For each system we describe examples of evidence-informed services, policies or programs that (1) prevent disabilities and promote health, (2) protect and preserve families and neighborhoods, and (3) provide quality care. Prioritizing the promotion of children's MEB health by all state systems can shape U.S. children's health and well-being for generations to come.

A number's game: Towards a solution to the policing of ringfenced COVID Hotspots.

ISSUED ADDRESSED: COVID-19 has highlighted the disruptive, cross-sectorial effects a sudden-onset pandemic has on a globally interconnected world. The control of community transmission requires the identification and isolation of hotspots, commonly achieved through blanket measures or through ring-fencing. A simpler and more readily policeable, and geographically more flexible system is needed that allows both law enforcement and the public to detect people moving outside the ringfenced areas. METHODS: A narrative examination of the border closure between New South Wales and Victoria in June to September 2020. RESULTS: Enforcement of people's movement in and out of ring-fenced areas relies on voluntary, ethical compliance coupled with legal prosecution of violators. Despite extensive community health promotion for COVID-safe behaviour, the events of 2020 showed multiple, flagrant violations which were caught during random spot checks, as well as at the Murray River, a hard border set up along readily controllable and patrollable features (bridges). CONCLUSIONS: Given that most medium and long-distance movement in Australia is vehicular-based, this paper advocates for the introduction of European-style local government area based car registration which makes 'out of bounds' vehicle traffic readily recognisable by their number plates. SO WHAT?: Public health promotion, coupled with convenient and ubiquitous observation and enforcement tool, is likely to moderate community behaviour and ensure increased compliance with the directives of health authorities and associated promotion of COVID-safe behaviour.

Linking key intervention timings to rapid declining effective reproduction number to quantify lessons against COVID-19.

Coronavirus disease 2019 (COVID-19) is currently under a global pandemic trend. The efficiency of containment measures and epidemic tendency of typical countries should be assessed. In this study, the efficiency of prevention and control measures in China, Italy, Iran, South Korea, and Japan was assessed, and the COVID-19 epidemic tendency among these countries was compared. Results showed that the effective reproduction number(Re) in Wuhan, China increased almost exponentially, reaching a maximum of 3.98 before a lockdown and rapidly decreased to below 1 due to containment and mitigation strategies of the Chinese government. The Re in Italy declined at a slower pace than that in China after the implementation of prevention and control measures. The Re in Iran showed a certain decline after the establishment of a national epidemic control command, and an evident stationary phase occurred because the best window period for the prevention and control of the epidemic was missed. The epidemic in Japan and South Korea reoccurred several times with the Re fluctuating greatly. The epidemic has hardly rebounded in China due to the implementation of prevention and control strategies and the effective enforcement of policies. Other countries suffering from the epidemic could learn from the Chinese experience in containing COVID-19.

'Policing' a pandemic: Garda wellbeing and COVID-19.

In response to the global pandemic COVID-19, the Irish government has called upon the Garda Síochána to implement an unparalleled mode of policing to mitigate and contain the spread of the Coronavirus. Studies investigating smaller scale epidemics, such as Severe Acute Respiratory Syndrome (SARS), indicate that staff at the frontlines of an outbreak are exposed to an insuperable amount of stress and experience increased psychological morbidities as a result. Furthermore, research not only indicates that heighted levels of psychological distress are an occupational hazard associated with the law enforcement profession, but that members of the Garda Síochána feel their mental health needs are largely unmet by their organisation. Given the pandemic's propensity to expose officers to indeterminate echelons of physical and psychological threat; there has never been a more appropriate time to explore the potential burdens associated with 'policing' a pandemic, question the governments capacity to address the psychological support needs of frontline professionals, and plan future research for best practice.
