Published: November 2018

AbstractBackgroundPathogens can survive for extended periods when incorporated into biofilm on dry hospital surfaces (ie, dry-surface biofilm, DSB). Bacteria within biofilm are protected from desiccation and have increased tolerance to cleaning agents and disinfectants.ObjectiveWe hypothesized that gloved hands of healthcare personnel (HCP) become contaminated with DSB bacteria and hence may transmit bacteria associated with healthcare-associated infections (HAIs).MethodStaphylococcus aureus DSB was grown in vitro on coupons in a bioreactor over 12 days with periodic nutrition interspersed with long periods of dehydration. Each coupon had ~107 DSB bacterial cells. Transmission was tested with nitrile, latex, and surgical gloves by gripping DSB-covered coupons then pressing finger tips onto a sterile horse blood agar surface for up to 19 consecutive touches and counting the number of colony-forming units (CFU) transferred. Coupons were immersed in 5% neutral detergent to simulate cleaning, and the experiment was repeated.ResultsBacterial cells were readily transmitted by all 3 types of gloves commonly used by HCP. Surprisingly, sufficient S. aureus to cause infection were transferred from 1 DSB touch up to 19 consecutive touches. Also, 6 times more bacteria were transferred by nitrile and surgical gloves than to latex gloves (P <.001). Treating the DSB with 5% neutral detergent increased the transmission rate of DSB bacteria 10-fold.ConclusionStaphylococcus aureus incorporated into environmental DSB and covered by extracellular polymeric substances readily contaminates gloved hands and can be transferred to another surface. These results confirm the possibility that DSB contributes to HAI acquisition.
Swampy Sugar Lands: Irrigation Dams and the Rise and Fall of Malaria in Puerto Rico, 1898–1962
Authors: Johnson Matthew P. 
Published: November 2018

AbstractTwo environmental re-engineering projects clashed in south-eastern Puerto Rico in the early twentieth century. Between 1910 and 1914 the Puerto Rican Irrigation Service built three large dams to water canefields owned by US sugar companies. The new canals and holding ponds created ideal breeding grounds for malaria-carrying mosquitoes, and demand for fieldworkers encouraged greater numbers of Puerto Ricans to work and live near these mosquito swarms. Malaria rates soared as a result. Meanwhile, public health officials tried to control malaria, but their efforts faltered, especially when efficient irrigation was prioritised above all else. It was not until the 1940s and 1950s that health officials controlled and then eliminated malaria. In Puerto Rico, malaria rose with the commitment to irrigated canefields and remained tenacious until wartime exigencies inspired greater control efforts, DDT became available and, most importantly, manufacturing eclipsed sugar production as the island's dominant economic activity.

Published: November 2018

AbstractBackgroundTo better understand the associations of childhood trauma and childhood disorder with past-year suicidality (thoughts, plans or attempts), we compared male military and civilian populations aged 18–60 years old.MethodsData derived from the 2010 Australian Defence Force (ADF) Mental Health Prevalence and Wellbeing Study and the 2007 Australian Bureau of Statistics Australian National Survey of Mental Health and Wellbeing were compared using logistic regression and Generalized Structural Equation Modelling (GSEM).ResultsA greater proportion of the ADF experienced suicidality than civilians. Those who experienced childhood trauma that was not interpersonal in nature were not at increased odds of suicidality, in either population. A higher proportion of the ADF experienced three or more types of trauma in childhood and first experienced three or more types of trauma in adulthood. Both were associated with suicidality in the ADF and civilians. Childhood anxiety had a strong and independent association with suicidality in the ADF (controlling for demographics and childhood trauma, adult trauma and adult onset disorder). Childhood anxiety fully mediated the relationship between childhood trauma and suicidality in the ADF, but not in civilians.ConclusionsThese data highlight the need to take a whole life approach to understanding suicidality, and the importance of categorizing the nature of childhood trauma exposure. Importantly, childhood anxiety was not only associated with suicidality, it fully mediated the relationship between childhood trauma and suicidality in the more trauma exposed (military) population only. These findings have the potential to inform the development of strategies for suicide prevention.
Perceptions of ageing and future aspirations by people with intellectual disability: a grounded theory study using photo-elicitation
Authors: Trip Henrietta , Whitehead Lisa , Crowe Marie 
Published: November 2018

AbstractInternationally, 1 per cent of the general population are living with an intellectual disability and life expectancy is increasing in line with global trends. The majority of people with an intellectual disability live with family. This represents a growing and largely ‘hidden’ population who have, or will have, additional needs as they and their family age. There is limited research about what is important for people with intellectual disability when thinking about getting older. This article reports on a study which explored the concept of ageing and future aspirations with 19 people living with an intellectual disability, aged 37–58 years of age (mean 48 years) and living with someone they identify as family. Using Charmaz's constructivist grounded theory approach and photo-elicitation, constant comparative analysis generated four themes: reciprocating relationships, emerging (in)dependence, configuring ageing and entertaining possibilities. As part of the interview process, photo-elicitation facilitated the expression of associations and perspectives about ageing and conceptualising the future for participants. The findings demonstrate the engagement of people with intellectual disabilities in research and provided unique insights into both their experiences and perspectives on ageing in the context of family. The need for greater flexibility in service planning and delivery are identified, alongside ensuring the meaningful inclusion of people with intellectual disability in decision-making about their own lives as they age.

AbstractSignificant ethnic and socio-economic disparities exist in infectious diseases (IDs) rates in New Zealand, so accurate measures of these characteristics are required. This study compared methods of ascribing ethnicity and socio-economic status. Children in the Growing Up in New Zealand longitudinal cohort were ascribed to self-prioritised, total response and single-combined ethnic groups. Socio-economic status was measured using household income, and both census-derived and survey-derived deprivation indices. Rates of ID hospitalisation were compared using linked administrative data. Self-prioritised ethnicity was simplest to use. Total response accounted for mixed ethnicity and allowed overlap between groups. Single-combined ethnicity required aggregation of small groups to maintain power but offered greater detail. Regardless of the method used, Māori and Pacific children, and children in the most socio-economically deprived households had a greater risk of ID hospitalisation. Risk differences between self-prioritised and total response methods were not significant for Māori and Pacific children but single-combined ethnicity revealed a diversity of risk within these groups. Household income was affected by non-random missing data. The census-derived deprivation index offered a high level of completeness with some risk of multicollinearity and concerns regarding the ecological fallacy. The survey-derived index required extra questions but was acceptable to participants and provided individualised data. Based on these results, the use of single-combined ethnicity and an individualised survey-derived index of deprivation are recommended where sample size and data structure allow it.
Human papillomaviruses 16 and 58 are distributed widely among women living in Shanghai, China, with high-grade, squamous intraepithelial lesions

AbstractThe distribution of human papillomaviruses (HPVs) must be understood for the control and prevention of cervical cancer. Community-based Papanicolaou and HPV DNA tests were performed on 41 578 women. The prevalences of HPV genotypes 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66 and 68 were assessed. In total, 10% women were infected/co-infected by these HPVs. The infection rate increased from 7.1% in women aged ⩽30 years to 10.4% in those aged 50–60 years, and then decreased slightly to 9.9% in those aged >60 years. The HPV 16 and 58 positivity rates were significantly higher among women with high-grade squamous intraepithelial lesions (HSILs) than among those with cervicitis/negativity for intraepithelial lesion or malignancy (NILM) or low-grade SILs (LSILs). The HPV 18, 52 and 68 infection rates were significantly lower in women with HSILs than in those with NILM or LSILs. The proportion of women infected by multiple HPV strains was higher among those with HSILs. The proportions of the five most common genotypes, HPV 16, 18, 33, 52 and 58, increased with the number of co-infecting strains. HPV 16 and 58 were the high-risk HPVs in the Shanghai community and should be the focus in HPV screening and vaccination.

SummaryIn this study we analyzed whether the in vivo storage of oocytes (time after ovulation until fertilization) affects the survival and the ploidy status of the yellowtail tetra Astyanax altiparanae. Fish were induced to spawn and, after ovulation, a small aliquot was stripped and immediately fertilized (positive control group). Subsequently, aliquots (~150 oocytes) were stripped and fertilized at various time points of 60, 120, 180 or 240 min. Developmental stages, abnormalities, survival and the ploidy status of the hatched larvae were examined. As expected, in the control group, 100% of the larvae were diploid. Conversely, triploid individuals were observed just at the 60 min treatment time point (0.6%). In vivo storage of oocytes also influenced the survival rates (P < 0.05); the 180 and 240 min samples, respectively, presented lower survival rates at gastrula (50.10±6.26% and 40.92±5.32%), and somite (17.80±5.14% and 4.41±2.76%) stages and lower hatching rates (12.01±4.04% and 4.41±2.76%). A higher percentage (99.27±0.40%) of normal larvae and only a few abnormal larvae (0.73±0.40%) were observed in the control group (P = 0.0000). This observation did not differ from that observed at the 60 min treatment point (P = 0.9976). A significant increase in the percentage of abnormalities was observed in the other treatments, and, after 240 min, the highest percentage of abnormal larvae was seen (P=0.0024; 83.33±16.67%). In conclusion, we showed that oocyte ageing had a significant effect on survival and may affect the ploidy status in A. atiparanae.
Different Levels of Government, Different Levels of Political Competence?
Authors: Chou Mark 
Published: November 2018

ABSTRACTIn federal political systems such as the United States, there has long existed a view that citizens should be more politically competent at the local level than at the federal level of government. Recent studies have challenged this view. This article argues that these findings may reflect only one part of the broader picture. Through a review of two recent studies, I contend that research in this realm must consider more than only the level of government. Odd as this sounds, assumptions about varying levels of political competence at different levels of government have always been premised on the notion that local-level politics is smaller and less complex than federal-level politics. However, when local politics takes place today against the backdrop of small villages and towns as well as in large cities, these are assumptions that must be reevaluated.
Persian Poetry, Sufism and Ismailism: The Testimony of Khwājah Qāsim Tushtarī’sRecognizing God
Authors: VIRANI SHAFIQUE N. 
Published: November 2018

AbstractKhwājah Qāsim Tushtarī’s recently discovered Recognizing God (Maʿrifat-i Khudāy taʿālā) is one of the only texts known to have survived from the early Alamūt period of Ismaili Muslim history. This article analyses the work in the context of the “new Invitation” (daʿwat-i jadīd) to the Ismaili faith that al-Shahrastānī (d. 548/1153) tells us was inaugurated by the Fāṭimid Imam al-Mustanṣir billāh (d. 487/1094) and championed by Ḥasan-i Ṣabbāḥ (d. 518/1124). The text emphasises that the ultimate purpose of human existence is to know God, and that the path to this knowledge is through the Imam of the Time. The concepts of the ‘true teacher’ (muʿallim-i ṣādiq) and ‘sage’ (ḥakīm) are examined and the literary culture fostered at the Ismaili fortresses, particularly Girdkūh, is explored. Significantly, the article draws attention to the position of Sanāʾī Ghaznawī (d.circa525/1131) in Persian Ismaili literature and to the very early development of pious, devotional and homiletic poetry as well as the “mathnawīmetre” in Ismaili environments, which may have helped set the stage for some of the most significant poetic achievements of mystical Islam: the writings of Farīd al-Dīn ʿAṭṭār (d.circa618/1221) and Jalāl al-Dīn Rūmī (d. 672/1273).
Functional Imaging of Neurotransmitters in Hymenolepis diminuta Treated with Senna Plant Through Light and Confocal Microscopy

Published: November 2018

AbstractPrevious studies have shown the anthelmintic efficacy of Senna alata, Senna alexandrina and Senna occidentalis on the zoonotic parasite Hymenolepis diminuta through microscopic studies on morphological structure. The present study is based on the light and confocal microscopic studies to understand if Senna extracts affect neurotransmitter activity of the parasites. A standard concentration (40 mg/mL) of the three leaf extracts and one set of 0.005 mg/mL concentration of the reference drug praziquantel were tested against the parasites, keeping another set of parasites in phosphate buffer saline as a control. Histochemical studies were carried out using acetylthiocholine iodide as the substrate and acetylcholinesterase as the marker enzyme for studying the expression of the neurotransmitter of the parasite and the staining intensity was observed under a light microscope. Immunohistochemical studies were carried out using anti serotonin primary antibody and fluorescence tagged secondary antibody and observed using confocal microscopy. Intensity of the stain decreases in treated parasites compared with the control which implies loss of activity of the neurotransmitters. These observations indicated that Senna have a strong anthelmintic effect on the parasite model and thus pose as a potential anthelmintic therapy.
The Psychological Profile of Church of England Male Archdeacons at the Beginning of the Twenty-first Century: Drawing on Psychological Type and Temperament Theory
Authors: Francis Leslie J. , Whinney Michael 
Published: November 2018

AbstractRecent discussion and research has pointed to the changing functions of archdeacons within the Church of England as the role has become expanded to combine both the traditional statutory functions with flexible and visionary leadership skills within a changing church. This study draws on data collected in 2009 from 186 active and retired male archdeacons in order to assess the psychological profile established by that time. Compared with the psychological profile of 626 clergymen, male archdeacons were much more likely to prefer the SJ temperament (60 per cent compared with 31 per cent), a temperament ideally suited for effective administration of the statutory functions. As a consequence, preference for intuition was lower among male archdeacons (38 per cent compared with 62 per cent), as was preference for perceiving (9 per cent compared with 32 per cent), qualities core for flexibility and visionary leadership.
Tracking natural organic carbon in the River Clyde, UK, using glycerol dialkyl glycerol tetraethers
Authors: Lopes dos Santos Raquel A. , Vane Christopher H. 
Published: November 2018

ABSTRACTSurface sediments from a 100-km stretch of the River Clyde, UK, and its estuary were analysed for glycerol dialkyl glycerol tetraethers (GDGTs) to track the downstream changes in the source of organic matter (OM) and to evaluate the impact of urbanisation. Bacterial membrane lipids, named branched GDGTs (brGDGTs), produced in soils and rivers ranged from 1.6 to 58μgg−1 organic carbon (OC) and the isoprenoid GDGT crenarchaeol, mainly from marine archaea, ranged from 0.01 to 42μgg−1 OC. The highest brGDGT concentrations were in the upper river, in Glasgow city and in the outer estuary, suggesting higher soil-derived OM input. By contrast, crenarchaeol concentrations gradually increased from the tidal weir in Glasgow towards the sea. This spatial distribution of the tetraethers was reflected in the branched and isoprenoid tetraether (BIT) index, a proxy for soil versus marine carbon. The highest BIT values (1.0) occurred upstream, estuarine values ranged from 0.9 to 0.6 and the lowest values (0.4) were found in the outer estuary. An independent proxy for soil-derived OM, stable carbon isotope (δ13C) values, showed a comparable decrease in terrigenous OM contribution towards the sea, but was more variable compared to the BIT. Conversely, carbon/nitrogen (C/N) showed a constant trend, suggesting that it is not a reliable indicator of OM source in the Clyde. Neither BIT, δ13C nor C/N were able to reflect the input of urban effluents from Glasgow.
Controls on surface water quality in the River Clyde catchment, Scotland, UK, with particular reference to chromium and lead

Published: November 2018

ABSTRACTThree collated geochemical surveys of surface water in the Clyde catchment have established the spatial variability in water composition, primarily under baseflow conditions. The waters are broadly pH-neutral to alkaline (maximum pH 8.7) in the lowlands, but mildly acidic in uplands on the catchment periphery. Electrical conductance is relatively high in lowland streams (maximum 8320μgL–1), with lower values in the uplands. Dissolved chromium (Cr; <0.05–971μgL–1) and lead (Pb; <0.05–19.4μgL–1) are of importance due to recognised pollution sources within the catchment. High aqueous Cr concentrations (>5μgL–1) are recorded in urban areas associated with the disposal of alkaline industrial chromite ore processing residue. Under such conditions, Cr probably occurs as Cr(VI). Numerous relatively high Pb values occur in the upland and urban areas. These are likely to be associated with a combination of soil reactions, diffuse pollution and contamination from Pb mineralisation/mining. Pb has a stronger correlation with water pH than with stream sediment Pb content, suggesting that pH has a greater control on Pb mobility than host-rock Pb. Exceedances of water-quality standards are <1% for both Cr and Pb across the catchment. Absolute exceedances are more extreme for Cr than for Pb, highlighting the scale of the Cr pollution problem for urban surface water within the catchment.
Factors affecting Observers’ Accuracy when Assessing Credibility: The Effect of the Interaction between Media, Senders’ Competence and Veracity

Published: November 2018

AbstractThe present experiment examined how the interaction between senders’ communicative competence, veracity and the medium through which judgments were made affected observers’ accuracy. Stimuli were obtained from a previous study. Observers (N = 220) judged the truthfulness of statements provided by a good truth teller, a good liar, a bad truth teller, and a bad liar presented either via an audio-only, video-only, audio-video, or transcript format. Log-linear analyses showed that the data were best explained via the saturated model, therefore indicating that all the four variables interacted, G2(0) = 0, p = 1, Q2 = 1. Follow-up analyses showed that the good liar and bad liar were best evaluated via the transcript (z = 2.5) and the audio-only medium (z = 3.9), respectively. Both the good truth teller and the bad truth teller were best assessed through the audio-video medium (z = 2.1, good truth teller, z = 3.4, bad truth teller). Results indicated that all the factors interacted and played a joint role on observers’ accuracy. Difficulties and suggestions for choosing the right medium are presented.
The Influence of Interannual Climate Variability on Regional Violent Crime Rates in the United States

Published: November 2018

AbstractWhile the impact of climate on regional geopolitical stability and large‐scale conflict has garnered increased visibility in recent years, the effects of climate variability on interpersonal violent crime have received only limited scientific attention. Though earlier studies have established a modest correlation between temperature and violent crime, the underlying seasonality in both variables was often not controlled for and spatial heterogeneity of the statistical relationships has largely been overlooked. Here a method of spatial aggregation is applied to the United States, enabling a systematic investigation into the observed relationships between large‐scale climate variability and regionally aggregated crime rates. This novel approach allows for differentiation between the effects of two previously proposed mechanisms linking climate and violent crime, the Routine Activities Theory and Temperature‐Aggression Hypothesis. Results indicate large and statistically significant positive correlations between the interannual variability of wintertime air temperature and both violent and property crime rates, with negligible correlations emerging from summertime data. Results strongly support the Routine Activities Theory linking climate and violent crime, with climate variability explaining well over a third of the variance of wintertime violent crime in several broad regions of the United States. Finally, results motivate the development of observationally constrained empirical models and their potential application to seasonal and potentially longer‐term forecasts.
