Cutting the Lawn - Natural Burial and its Contribution to the Delivery of Ecosystem Services in Urban Cemeteries
This article investigates the impact of natural burial on the delivery of ecosystem services (ESs) in urban cemeteries in England that are owned and managed by local authorities. Local authority natural burial sites have received far less attention from researchers than independent sites developed by farmers, charitable trusts, funeral directors and land owners. Here we argue that the local authority hybrid cemeteries that combine natural burial with traditional graves may have a far greater impact in delivering regulatory and cultural ecosystem services than the much larger and frequently more environmentally ambitious natural burial grounds developed by the independent sector. The article presents three case studies of cemeteries, each of which represents a different interpretation of natural burial. Two have retrofitted natural burial into an existing cemetery landscape. The third is a new cemetery where natural burial was included with traditional burial in the original design brief and planning application. The research reveals how natural burial is transforming the traditional cemetery, with its focus on an intensively managed lawn aesthetic, towards a more habitat rich and spatially complex landscape with its own distinctive identity. The research also reveals how natural burial (within the unique constraints of UK burial culture that does not permit the recycling of burial space) is increasing the burial capacity of urban cemeteries by accessing land and grave space that might not be suitable or appropriate for more traditional forms of burial
Knowledge of pelvic floor problems: a study of third trimester, primiparous women
INTRODUCTION AND HYPOTHESIS: Pelvic floor problems in women (urinary incontinence, faecal incontinence, uterovaginal prolapse) are common, and have an adverse effect on quality of life. We hypothesized that there is low knowledge of these problems amongst primiparous women in their third trimester of pregnancy. METHODS: We conducted a cross-sectional study in antenatal clinics of three hospitals in London, UK, from 2011 to 2013. Primiparous women aged ≥18 years and in the third trimester of pregnancy answered questions on pelvic floor problems. Knowledge scores were calculated based on the proportion of questions answered correctly. RESULTS: A total of 249 women completed the question set. The average knowledge score across all domains was low at 45 %. Scores were lowest for the less common problems of faecal incontinence (35 %) and prolapse (36 %). The score for urinary incontinence was higher at 63 %, but low when questions explored more detailed levels of knowledge (41 %). Knowledge scores were positively associated with both education to tertiary level and the use of books as the information source on pregnancy and delivery. Only 35 % of women cited antenatal classes as a source. CONCLUSIONS: Knowledge of pelvic floor problems is low amongst third-trimester, primiparous women in this London-based population. Adequate knowledge of these problems is important for women to be able to make informed choices about their antenatal care and to seek help if problems arise. The data suggest scope for health-care professionals to raise these issues early during pregnancy, and to help women access accurate sources of information

What’s sex got to do with it? A family-based investigation of growing up heterosexual during the twentieth century
This paper explores findings from a cross-generational study of the making of heterosexual relationships in East Yorkshire, which has interviewed women and men within extended families. Using a feminist perspective, it examines the relationship between heterosexuality and adulthood, focussing on sexual attraction, courtship, first kisses, first love and first sex, as mediated within family relationships, and at different historical moments. In this way, the contemporary experiences of young people growing up are compared and contrasted with those of mid-lifers and older adults who formed heterosexual relationships within the context of the changing social and sexual mores of the 1960s/1970s, and the upheavals of World War Two
The interview as narrative ethnography : seeking and shaping connections in qualitative research.
Acts of counter-subjectification in qualitative research are always present but are often submerged in accounts that seek to locate the power of subjectification entirely with the researcher. This is particularly so when talking to people about sensitive issues. Based on an interview-based study of infertility and reproductive disruption among British Pakistanis in Northeast England, we explore how we, as researchers, sought and were drawn into various kinds of connections with the study participants; connections that were actively and performatively constructed through time. The three of us that conducted interviews are all female academics with Ph.Ds in anthropology, but thereafter our backgrounds, life stories and experiences diverge in ways that intersected with those of our informants in complex and shifting ways. We describe how these processes shaped the production of narrative accounts and consider some of the associated analytical and ethical implications
'Soldiering by consent' amd military-civil relations: Military transition into the public space of policing
Growth in the Armed Forces undertaking public policing is occurring in the United Kingdom and elsewhere and as such a complex security landscape emerges, both practically and conceptually. The aim here is to pose questions of the manifest and latent issues in the assemblage of multiple actors in public policing. It aks to reader to consider the implications of military actors transitioning from defence duties ordinarily associated with military work, to policing activities in public spaces. Taking the London 2012 Olympic Games as our point of reference, this article argues that to understand military presence, their role must be considered in the broader context of military and policing functions, the ‘war on terror’, accountability, and future priorities for public policing. We must be careful not to assign the presence of the military into pre-existing understandings of how mega-events should be secured – the military patrolling the streets of London represents more. Instead, as their presence comes to be legitimate in certain geopolitical contexts, critical questions must be asked especially as public and private arrangements are continually reworked in the domestic fight against terrorism
Assessment of dispersion of airborne particles of oral/nasal fluid by high flow nasal cannula therapy
Background
Nasal High Flow (NHF) therapy delivers flows of heated humidified gases up to 60 LPM (litres per minute) via a nasal cannula. Particles of oral/nasal fluid released by patients undergoing NHF therapy may pose a cross-infection risk, which is a potential concern for treating COVID-19 patients.
Methods
Liquid particles within the exhaled breath of healthy participants were measured with two protocols: (1) high speed camera imaging and counting exhaled particles under high magnification (6 participants) and (2) measuring the deposition of a chemical marker (riboflavin-5-monophosphate) at a distance of 100 and 500 mm on filter papers through which air was drawn (10 participants). The filter papers were assayed with HPLC. Breathing conditions tested included quiet (resting) breathing and vigorous breathing (which here means nasal snorting, voluntary coughing and voluntary sneezing). Unsupported (natural) breathing and NHF at 30 and 60 LPM were compared.
Results
Imaging: During quiet breathing, no particles were recorded with unsupported breathing or 30 LPM NHF (detection limit for single particles 33 μm). Particles were detected from 2 of 6 participants at 60 LPM quiet breathing at approximately 10% of the rate caused by unsupported vigorous breathing. Unsupported vigorous breathing released the greatest numbers of particles. Vigorous breathing with NHF at 60 LPM, released half the number of particles compared to vigorous breathing without NHF.
Chemical marker tests: No oral/nasal fluid was detected in quiet breathing without NHF (detection limit 0.28 μL/m3). In quiet breathing with NHF at 60 LPM, small quantities were detected in 4 out of 29 quiet breathing tests, not exceeding 17 μL/m3. Vigorous breathing released 200–1000 times more fluid than the quiet breathing with NHF. The quantities detected in vigorous breathing were similar whether using NHF or not.
Conclusion
During quiet breathing, 60 LPM NHF therapy may cause oral/nasal fluid to be released as particles, at levels of tens of μL per cubic metre of air. Vigorous breathing (snort, cough or sneeze) releases 200 to 1000 times more oral/nasal fluid than quiet breathing (p < 0.001 with both imaging and chemical marker methods). During vigorous breathing, 60 LPM NHF therapy caused no statistically significant difference in the quantity of oral/nasal fluid released compared to unsupported breathing. NHF use does not increase the risk of dispersing infectious aerosols above the risk of unsupported vigorous breathing. Standard infection prevention and control measures should apply when dealing with a patient who has an acute respiratory infection, independent of which, if any, respiratory support is being used
Testing epidemiological functional groups as predictors of avian haemosporidia patterns in southern Africa
Understanding the dynamics of multihost parasites and the roles of different host species in parasite epidemiology requires consideration of the whole animal community. Host communities may be composed of hundreds of interacting species, making it necessary to simplify the problem. One approach to summarizing the host community in a way that is relevant to the epidemiology of the parasite is to group host species into epidemiological functional groups (EpiFGs). We used EpiFGs to test our understanding of avian malaria (Plasmodium and Haemoproteus) dynamics in four communities of wetland-associated birds in southern Africa. Bird counts and captures were undertaken every 2–4 months over 2 yr and malaria was diagnosed by nested PCR. One hundred and seventy-six bird species were allocated to a set of EpiFGs according to their assumed roles in introducing and maintaining the parasite in the system. Roles were quantified as relative risks from avian foraging, roosting, and movement ecology and assumed interaction with vector species. We compared our estimated a priori risks to empirical data from 3414 captured birds from four sites and 3485 half-hour point counts. After accounting for relative avian abundance, our risk estimates significantly correlated with the observed prevalence of Haemoproteus but not Plasmodium. Although avian roosting height (for both malarial genera) and movement ecology (for Plasmodium) separately influenced prevalence, host behavior alone was not sufficient to predict Plasmodium patterns in our communities. Host taxonomy and relative abundance were also important for this parasite. Although using EpiFGs enabled us to predict the infection patterns of only one genus of heamosporidia, our approach holds promise for examining the influence of host community composition on the transmission of vector-borne parasites and identifying gaps in our understanding of host–parasite interactions.

Jography: Exploring meanings, experiences and spatialities of recreational road-running
Jogging is a relatively under-researched mobile practice with much existing literature focusing on ‘serious’ and competitive running. In this paper, we provide an account of some of the movements, meanings and experiences that together help produce the practice of jogging in the south-western English city of Plymouth. Drawing upon participant diaries and interviews, we uncover rich detail about how joggers ascribe not one but a number of meanings to their practice. Some of these are positive, some are negative; some complement each other and some compete with each other. We also consider how the experiences of joggers can be shaped by their ongoing need to develop tactics capable of enabling them to negotiate space with non-joggers. This is in some contrast to more competitive running that occurs in the separated space of an athletics track. Our sense is that better awareness of the meanings and experiences of jogging will be of value if the advertised health and sustainability benefits of the practice are to be more effectively encouraged and promoted
