East London Project: a participatory mixed-method evaluation on how removing enforcement could affect sex workers' safety, health and access to services in East London.

Background: Sex workers' risk of violence and ill-health is shaped by their work environments, community and structural factors, including criminalisation.

Aim: We evaluated the impact of removing police enforcement on sex workers' safety, health and access to services.

Design: Mixed-methods participatory study comprising qualitative research, a prospective cohort study, mathematical modelling and routine data collation.

The impact of policing and homelessness on violence experienced by women who sell sex in London: a modelling study.

Street-based sex workers experience considerable homelessness, drug use and police enforcement, making them vulnerable to violence from clients and other perpetrators. We used a deterministic compartmental model of street-based sex workers in London to estimate whether displacement by police and unstable housing/homelessness increases client violence. The model was parameterized and calibrated using data from a cohort study of sex workers, to the baseline percentage homeless (64%), experiencing recent client violence (72%), or recent displacement (78%), and the odds ratios of experiencing violence if homeless (1.

Health risks at work mean risks at home: Spatial aspects of COVID-19 among migrant workers in precarious jobs in England.

During COVID-19 lockdowns in England, 'key workers' including factory workers, carers and cleaners had to continue to travel to workplaces. Those in key worker jobs were often from more marginalised communities, including migrant workers in precarious employment. Recognising space as materially and socially produced, this qualitative study explores migrant workers' experiences of navigating COVID-19 risks at work and its impacts on their home spaces.

COVID-19 vaccination decisions among Gypsy, Roma, and Traveller communities: A qualitative study moving beyond "vaccine hesitancy".

Background: Many people refuse vaccination and it is important to understand why. Here we explore the experiences of individuals from Gypsy, Roma, and Traveller groups in England to understand how and why they decided to take up or to avoid COVID-19 vaccinations.

Methods: We used a participatory, qualitative design, including wide consultations, in-depth interviews with 45 individuals from Gypsy, Roma, and Traveller, communities (32 female, 13 male), dialogue sessions, and observations, in five locations across England between October 2021 and February 2022.

Community-led responses to COVID-19 within Gypsy and Traveller communities in England: A participatory qualitative research study.

Individuals were asked to play an active role in infection control in the COVID-19 pandemic. Yet while government messages emphasised taking responsibility for the public good (e.g.

The Effect of Systemic Racism and Homophobia on Police Enforcement and Sexual and Emotional Violence among Sex Workers in East London: Findings from a Cohort Study.

There is extensive qualitative evidence of violence and enforcement impacting sex workers who are ethnically or racially minoritized, and gender or sexual minority sex workers, but there is little quantitative evidence. Baseline and follow-up data were collected among 288 sex workers of diverse genders (cis/transgender women and men and non-binary people) in London (2018-2019). Interviewer-administered and self-completed questionnaires included reports of rape, emotional violence, and (un)lawful police encounters.

Effect of police enforcement and extreme social inequalities on violence and mental health among women who sell sex: findings from a cohort study in London, UK.

Objectives: To examine legal and social determinants of violence, anxiety/depression among sex workers.

Methods: A participatory prospective cohort study among women (inclusive of transgender) ≥18 years, selling sex in the last 3 months in London between 2018 and 2019. We used logistic generalised estimating equation models to measure associations between structural factors on recent (6 months) violence from clients or others (local residents, strangers), depression/anxiety (Patient Health Questionnaire-4).

Hole wave functions and transport with deazaadenines replacing adenines in DNA.

Transport of a hole along the base stack of DNA is relatively facile for a series of adenines (As) paired with thymines (Ts) or for a series of guanines (Gs) paired with cytosines (Cs). However, the speed at which a hole was found to travel was much too small to make useful semiconductor-type devices. Quite recently it was found that replacing one of the electronegative nitrogens (N3 or N7) with a carbon and a hydrogen, thus turning A into deazaadenine, increased the hole speed in what was A/T by a factor 30.
