Jacobs argued that grand planning schemes intending to redevelop large swaths of a city according to a central theoretical framework fail because planners do not understand that healthy cities are organic, spontaneous, messy, complex systems that result from evolutionary processes. She argued that a gradual pace of redevelopment would facilitate maintenance of existing interpersonal ties. This paper operationalises the concept of pace of development within a cross-sectional framework as the 'age diversity of housing'. Analysis of a population-based multilevel community survey of Chicago linked with census housing data predicts individual perceptions of neighbourhood social relations (cohesion, control, intergenerational closure and reciprocal exchange). A gradual pace of redevelopment resulting in historical diversity of housing significantly predicts social relations, lending support to Jacobs's claims.

Public health researchers have identified numerous health implications associated with land use. However, it is unclear which of multiple methods of data collection most accurately captures land use, and "gold standard" methods vary by discipline. Five desirable features of environmental data sources are presented and discussed (cost, coverage, availability, construct validity, and accuracy). Potential accuracy issues are discussed by using Kappa statistics to evaluate the level of agreement between data sets collected by two methods (systematic social observation [SSO] by trained raters and publicly available data from aerial photography coded using administrative records) from the same blocks in Chicago, Illinois. Significant Kappa statistics range from 0.19 to 0.60, indicating varying levels of intersource agreement. Most land uses are more likely to be reported by researcher-designed direct observation than in the publicly available data derived from aerial photography. However, when cost, coverage, and availability outweigh a marginal improvement in accuracy and flexibility in land-use categorization, coded aerial photography data may be a useful data source for health researchers. Greater interdisciplinary and interorganization collaboration in the production of ecological data is recommended to improve cost, coverage, availability, and accuracy, with implications for construct validity.

Lifestyle and informal sports have been recognised by policy makers as offering opportunities to increase participation in physical activity, particularly amongst hard to reach groups. Lifestyle sports are, however, double edged in their potential to achieve these goals. Their playful and non-traditional features may attract new participants less interested in traditional sports but the very liquidity of these activities may mean that the engagement of participants is fragmented and not sustained beyond a particular period in their lives. This article presents the perspective of mountain biking user-managers; those involved in the delivery, clubs and communities of mountain bikers across the United Kingdom. Findings suggest that whilst lifestyle sport communities are dependent on the work of formalised clubs to gain access to the funding and resources they need to sustain their activities, core participants will not always want to have to liaise or become involved formally within a club structure. In addition, clubs will not succeed in delivering sustained activities in line with sport policy to increase and maintain participation by relying on individual grants and without the support of an active informal user community. Accounts highlight the importance of engaging informal user communities with a sense of ownership such as locals to ensure new participants are integrated and the community is able to replenish. ; This is an Accepted Manuscript of an article published by Taylor & Francis in International Journal of Sport Policy and Politics on 22/02/2017, available online: https://www.tandfonline.com/doi/full/10.1080/19406940.2017.1289236 Accepted manuscript would have had 18 months embargo according to Sherpa Romeo (https://v2.sherpa.ac.uk/id/publication/5441) but it was deposited to the repository of the University of Brighton before the deposit at UoB Repository.

Young people have been identified as a key target group for whom participation in sport and physical activity could have important benefits to health and well-being and consequently have been the focus of several government policies to increase participation in the UK. Lifestyle sports represent one such strategy for encouraging and sustaining new engagements in sport and physical activity in youth groups, however, there is at present a lack of understanding of the use of these activities within policy contexts. This paper presents findings from a government initiative which sought to increase participation in sport for young people through provision of facilities for mountain biking in a forest in south-east England. Findings from qualitative research with 40 young people who participated in mountain biking at the case study location highlight the importance of non-traditional sports as a means to experience the natural environments through forms of consumption which are healthy, active and appeal to their identities. In addition, however, the paper raises questions over the accessibility of schemes for some individuals and social groups, and the ability to incorporate sports which are inherently participant-led into state-managed schemes. Lifestyle sports such as mountain biking involve distinct forms of participation which present a challenge for policy-makers who seek to create and maintain sustainable communities of youth participants. ; Accepted manuscript would have had 18m embargo from publication date (end of embargo 05/11/2015) according to https://v2.sherpa.ac.uk/id/publication/61108 Deposited to UoB repository alm6ost 6 years after embargo ended and had been priory deposited to Uni of Brighton repository https://research.brighton.ac.uk/en/publications/power-space-and-the-new-stadium-the-example-of-arsenal-football-c before UoB repository.

AbstractMost of what is known about the association between children's executive function (EF) and school readiness skills is derived from research conducted in Western countries. We tested whether these associations were evident in a middle‐income country context. Participants were 1,480 children, aged 4–7 years old, who participated in an endline assessment of the Tayari program, an early childhood education (ECE) model that is being delivered by the Kenyan education system. High rates of task completion, low rates of floor effects, and high rates of assessor quality ratings supported the feasibility of large‐scale direct assessments of EF with young children. Assessor ratings of children's attention‐related behaviors during testing were positively associated with their performance on EF tasks (rs = 0.12–0.27). An EF composite score was not related to demographic factors or to children's exposure to the Tayari program. However, the EF composite score was uniquely associated with performance‐based measures of early literacy (β = 0.18, 95% confidence interval [CI] = 0.05, 0.31), early numeracy (β = 0.16, 95% CI = 0.07, 26), and social‐emotional competencies (β = 0.12, 95% CI = 0.03, 0.20), even after adjustment for multiple covariates. These results are discussed with respect to the ways in which EF skills inform ongoing efforts to invest in ECE in low‐ and middle‐income countries.

AbstractIntroductionBarriers to pre‐exposure prophylaxis (PrEP) access have limited its reach to priority populations. Community‐based mobile clinics have potential to broaden PrEP engagement. We evaluated reach and persistence for fixed and mobile clinic cohorts in Miami‐Dade County, Florida.MethodsThis observational cohort study analysed data from 1896 clients engaged through our fixed or mobile clinic from August 2018 to March 2023. Services were offered at no cost to clients. The same staff and package of barrier‐lowering strategies was deployed across fixed and mobile clinic sites. Chi‐square and Fisher's exact test or the Kruskal–Wallis test were used to test for differences in characteristics across sites as well as across services sought. Kaplan–Meier curves were generated to evaluate persistence on PrEP and in care, defined as completion of at least one clinic visit (including PrEP prescribing, for PrEP persistence, or for any reason, for persistence in care) within 24 weeks of the prior visit. Cox proportional hazards models were used to evaluate risk factors for discontinuation of PrEP or clinic care by 48 weeks by gender, race, ethnicity, insurance status and site.ResultsThe fixed and mobile clinics reached 781 and 1109 clients, respectively, during the study period. The median client age was 35 years; the majority (70.4%) of clients were cisgender men, identified as Hispanic/Latino (62.5%) and were men who have sex with men (54.5%). The mobile clinic extended reach to a higher proportion of cisgender women (32.1% mobile vs. 12.9% for fixed clinic), Black clients (34.5% vs. 13.1%) and older clients (median 37 vs. 33 years) compared with the fixed setting. Uninsured individuals, men and those who initiated services in the mobile clinic were more likely to continue PrEP to 48 weeks (HR: 1.20, p = 0.01; HR: 2.02, p<0.01; HR: 1.68, p<0.01, respectively). Persistence did not differ by race or ethnicity.ConclusionsA mobile clinic strategy for PrEP engagement can increase reach to key populations underrepresented in HIV prevention care including cisgender women and Black clients. Persistence in PrEP was increased for the mobile clinic cohort, suggesting an additional benefit to this modality beyond other barrier‐lowering strategies employed in our fixed and mobile clinics.
