Spatial clusters of gonorrhoea in England with particular reference to the outcome of partner notification: 2012 and 2013

Background: This study explored spatial-temporal variation in diagnoses of gonorrhoea to identify and quantify endemic areas and clusters in relation to patient characteristics and outcomes of partner notification (PN) across England, UK. Methods: Endemic areas and clusters were identified using a two-stage analysis with Kulldorff’s scan statistics (SaTScan). Results Of 2,571,838 tests, 53,547 diagnoses were gonorrhoea positive (positivity = 2.08%). The proportion of diagnoses in heterosexual males was 1.5 times that in heterosexual females. Among index cases, men who have sex with men (MSM) were 8 times more likely to be diagnosed with gonorrhoea than heterosexual males (p<0.0001). After controlling for age, gender, ethnicity and deprivation rank, 4 endemic areas were identified including 11,047 diagnoses, 86% of which occurred in London. 33 clusters included 17,629 diagnoses (34% of total diagnoses in 2012 and 2013) and spanned 21 locations, some of which were dominated by heterosexually acquired infection, whilst others were MSM focused. Of the 53,547 diagnoses, 14.5% (7,775) were the result of PN. The proportion of patients who attended services as a result of PN varied from 0% to 61% within different age, gender and sexual orientation cohorts. A third of tests resulting from PN were positive for gonorrhoea. 25% of Local Authorities (n = 81, 95% CI: 20.2, 29.5) had a higher than expected proportion for female PN diagnoses as compared to 16% for males (n = 52, 95% CI: 12.0, 19.9). Conclusions: The English gonorrhoea epidemic is characterised by spatial-temporal variation. PN success varied between endemic areas and clusters. Greater emphasis should be placed on the role of PN in the control of gonorrhoea to reduce the risk of onward transmission, re-infection, and complications of infection

A Hierarchical Examination of the Immigrant Achievement Gap: The Additional Explanatory Power of Nationality and Educational Selectivity Over Traditional Explorations of Race and Socioeconomic Status

This study compared immigrant and nonimmigrant educational achievement (i.e., the immigrant gap) in math and reading by reexamining the explanatory power of race and socio-economic status (SES)—two variables, perhaps, most commonly considered in educational research and policy formation. Four research questions were explored through growth curve modeling, factor analysis, and regression analysis based on a sample of participants in the Early Childhood Longitudinal Study-Kindergarten Cohort of 1998 (ECLS-K) from kindergarten to eighth grade (N = 6,861). Findings indicated that immigrant students who had been in the United States since at least their preschool years had lower math and reading achievement than nonimmigrants when they began kindergarten. In both achievement areas, 1.75-generation students caught up to their nonimmigrant counterparts, but second-generation students did not. Additionally, nationality played a greater role in determining immigrant performance than did race. Furthermore, educational selectivity had explanatory power with regard to math outcomes in (a) accounting for gaps between immigrant and nonimmigrant achievement, (b) accounting for racial gaps in achievement among both 1.75- and second-generation immigrants, (c) accounting directly for achievement among 1.75-immigrants, and (d) moderating the explanatory power of SES among both 1.75- and second-generation immigrants. Finally, mother\u27s educational selectivity was positively associated with both parental involvement and center-based early childhood education, but not with parental warmth, relative care, nonrelative care, or participation in Head Start—independent of whether children were 1.75- or second-generation immigrants

Fireside corrosion degradation of ferritic alloys at 600°C in oxy-fired conditions

This paper reports the results of a study carried out to investigate the effects of simulated coal/biomass combustion conditions on the fireside corrosion. The 1000 h deposit recoat exposure (5 × 200 h cycles) was carried out at 600 °C. In these tests ferritic alloys were used 15Mo3, T22, T23 and T91. Kinetics data were generated for the alloys exposed using both traditional weight change methods and metal loss measurements. The highest rate of corrosion based on EDX results occurred under D1 deposit where provoke mainly by the formation of alkali iron tri-sulphate phase

Development of on-line FTIR spectroscopy for siloxane detection in biogas to enhance carbon contactor management

Activated carbon filters are used to limit engine damage by siloxanes when biogas is utilised to provide electricity. However, carbon filter siloxane removal performance is poorly understood as until recently, it had not been possible to measure siloxanes on-line. In this study, on-line Fourier Transform Infrared (FTIR) spectroscopy was developed to measure siloxane concentration in real biogas both upstream (86.1–157.5 mg m−3) and downstream (2.2–4.3 mg m−3) of activated carbon filters. The FTIR provided reasonable precision upstream of the carbon vessel with a root mean square error of 10% using partial least squares analysis. However, positive interference from volatile organic carbons was observed in downstream gas measurements limiting precision at the outlet to an RMSE of 1.5 mg m−3 (47.8%). Importantly, a limit of detection of 3.2 mg m−3 was identified which is below the recommended siloxane limit and evidences the applicability of on-line FTIR for this application

Islands of the Abject: Absence, trauma and memory in the cemetery island.

Cemetery islands–islands of death–are simultaneously real places as well as symbols of the ways in which death has been marginalized in the modern city. Since the nineteenth century, cemeteries on islands have tended to be quietly invisible places, reserved for the bodies of those who, in life, occupied the margins of human society: the deviants, the forgotten, the diseased and the insane. Places such as Hart Island, the vast potter’s field of New York City and Poveglia, the island where Venice’s plague victims were sent to die, remain resolutely out of sight and mind, hidden behind the shiny façade of the urban metropolis. Yet today such islands are also sites of transformation brought about by a growing interest in death-tourism, calls for public access to sites of heritage, and the continued real estate development of ‘authentic’ urban spaces. Even while some cemetery islands lie abandoned and ruined, other islands of death and marginalization have emerged to take their place as locales for the contemporary ‘Other’. It is these simultaneously transgressive and transformative qualities of cemetery islands that provide the main question for this paper: How might the dark histories of trauma and violence found within cemetery islands, be critically addressed within future representations of these islands? One cemetery island - Hart Island, located in New York City, is considered here as a generative landscape that has contributed to a discussion about continued practices of spatial exclusion and their potential transformation through alternative, experimental modes of art and design. This discussion is framed through Kristeva\u27s theories of the abject and Foucault\u27s notion of heterotopian space

The implementation of chlamydia screening: a cross-sectional study in the south east of England

Background England's National Chlamydia Screening Programme (NCSP) provides opportunistic testing for under 25 year-olds in healthcare and non-healthcare settings. The authors aimed to explore relationships between coverage and positivity in relation to demographic characteristics or setting, in order to inform efficient and sustainable implementation of the NCSP. Methods The authors analysed mapped NCSP testing data from the South East region of England between April 2006 and March 2007 inclusive to population characteristics. Coverage was estimated by sex, demographic characteristics and service characteristics, and variation in positivity by setting and population group. Results Coverage in females was lower in the least deprived areas compared with the most deprived areas (OR 0.48; 95% CI 0.45 to 0.50). Testing rates were lower in 20 1324-year-olds compared with 15 1319-year-olds (OR 0.69; 95% CI 0.67 to 0.72 for females and OR 0.67; 95% CI 0.64 to 0.71 for males), but positivity was higher in older males. Females were tested most often in healthcare services, which also identified the most positives. The greatest proportions of male tests were in university (27%) and military (19%) settings which only identified a total of 11% and 13% of total male positives respectively. More chlamydia-positive males were identified through healthcare services despite fewer numbers of tests. Conclusions Testing of males focused on institutional settings where there is a low yield of positives, and limited capacity for expansion. By contrast, the testing of females, especially in urban environments, was mainly through established healthcare services. Future strategies should prioritise increasing male testing in healthcare settings

Carbon footprint assessment of Western Australian Groundwater Recycling Scheme

This research has determined the carbon footprint or the carbon dioxide equivalent (CO2 eq) of potable water production from a groundwater recycling scheme, consisting of the Beenyup wastewater treatment plant, the Beenyup groundwater replenishment trial plant and the Wanneroo groundwater treatment plant in Western Australia, using a life cycle assessment approach. It was found that the scheme produces 1300 tonnes of CO2 eq per gigalitre (GL) of water produced, which is 933 tonnes of CO2 eq higher than the desalination plant at Binningup in Western Australia powered by 100% renewable energy generated electricity. A Monte Carlo Simulation uncertainty analysis calculated a Coefficient of Variation value of 5.4%, thus confirming the accuracy of the simulation. Electricity input accounts for 83% of the carbon dioxide equivalent produced during the production of potable water. The chosen mitigation strategy was to consider the use of renewable energy to generate electricity for carbon intensive groundwater replenishment trial plant. Depending on the local situation, a maximum of 93% and a minimum of 21% greenhouse gas saving from electricity use can be attained at groundwater replenishment trial plant by replacing grid electricity with renewable electricity. In addition, the consideration of vibrational separation (V-Sep) that helps reduce wastes generation and chemical use resulted in a 4.03 tonne of CO2 eq saving per GL of water produced by the plant
