Water You Waiting For? Assessment Of Water Quality Across Two Divergent Coastal Watersheds

Coastal zones are among the world’s most diverse and productive environments; they encompass a broad range of habitat types and harbor a rich and diverse array of organisms that provide ecosystem services that are critical to the livelihoods of people living in coastal zones. Understanding how human developments affects these coastal zones allows for the sustainable development of coastal resources with respect to future changes in land use and tourism. Comparing water quality indices between adjacent coastal watersheds that differ in land use and population densities allows for the investigation into these human influences. We conducted a comparative analysis of water quality indices across two divergent coastal watersheds (Dingle and Ballyferriter) on the Dingle Peninsula in Ireland. Dingle and Ballyferriter differ with respect to land use patterns and population densities. Preliminary analyses indicate yearly and seasonal differences between watersheds with respect to nitrate and phosphate load. In general, nutrient concentrations were higher in Dingle than in Ballyferriter. Species diversity within nearshore fish assemblages was also investigated across watersheds. Species diversity and abundance was greater in Dingle compared to Ballyferriter. We discuss these results with respect to land use patterns and population density

Mammographic breast density refines Tyrer-Cuzick estimates of breast cancer risk in high-risk women: findings from the placebo arm of the International Breast Cancer Intervention Study I

Introduction: Mammographic density is well-established as a risk factor for breast cancer, however, adjustment for age and body mass index (BMI) is vital to its clinical interpretation when assessing individual risk. In this paper we develop a model to adjust mammographic density for age and BMI and show how this adjusted mammographic density measure might be used with existing risk prediction models to identify high-risk women more precisely. Methods: We explored the association between age, BMI, visually assessed percent dense area and breast cancer risk in a nested case-control study of women from the placebo arm of the International Breast Cancer Intervention Study I (72 cases, 486 controls). Linear regression was used to adjust mammographic density for age and BMI. This adjusted measure was evaluated in a multivariable logistic regression model that included the Tyrer-Cuzick (TC) risk score, which is based on classical breast cancer risk factors. Results: Percent dense area adjusted for age and BMI (the density residual) was a stronger measure of breast cancer risk than unadjusted percent dense area (odds ratio per standard deviation 1.55 versus 1.38; area under the curve (AUC) 0.62 versus 0.59). Furthermore, in this population at increased risk of breast cancer, the density residual added information beyond that obtained from the TC model alone, with the AUC for the model containing both TC risk and density residual being 0.62 compared to 0.51 for the model containing TC risk alone (P =0.002). Approximately 16% of controls and 19% of cases moved into the highest risk group (8% or more absolute risk of developing breast cancer within 10 years) when the density residual was taken into account. The net reclassification index was +15.7%. Conclusions: In women at high risk of breast cancer, adjusting percent mammographic density for age and BMI provides additional predictive information to the TC risk score, which already incorporates BMI, age, family history and other classic breast cancer risk factors. Furthermore, simple selection criteria can be developed using mammographic density, age and BMI to identify women at increased risk in a clinical setting

Shades of empire: police photography in German South-West Africa

This article looks at a photographic album produced by the German police in colonial Namibia just before World War I. Late 19th- and early 20th-century police photography has often been interpreted as a form of visual production that epitomized power and regimes of surveillance imposed by the state apparatuses on the poor, the criminal and the Other. On the other hand police and prison institutions became favored sites where photography could be put at the service of the emergent sciences of the human body—physiognomy, anthropometry and anthropology. While the conjuncture of institutionalized colonial state power and the production of scientific knowledge remain important for this Namibian case study, the article explores a slightly different set of questions. Echoing recent scholarship on visuality and materiality the photographic album is treated as an archival object and visual narrative that was at the same time constituted by and constitutive of material and discursive practices within early 20th-century police and prison institutions in the German colony. By shifting attention away from image content and visual codification alone toward the question of visual practice the article traces the ways in which the photo album, with its ambivalent, unstable and uncontained narrative, became historically active and meaningful. Therein the photographs were less informed by an abstract theory of anthropological and racial classification but rather entrenched with historically contingent processes of colonial state constitution, socioeconomic and racial stratification, and the institutional integration of photography as a medium and a technology into colonial policing. The photo album provides a textured sense of how fragmented and contested these processes remained throughout the German colonial period, but also how photography could offer a means of transcending the limits and frailties brought by the realities on the ground.International Bibliography of Social Science

The Politics and Aesthetics of Non-Representation: Re-Imagining Ethnographic Cinema with Apichatpong Weerasethakul

This article argues that the work of Thai filmmaker Apichatpong Weerasethakul offers conceptual and methodological tools that may contribute to the re-imagination of ethnographic cinema beyond representation. Weerasethakul’s films emerge out of a para-ethnographic engagement with people and places, rely on participatory methods and operate as hosting devices for a multiplicity of subaltern beings and stories. They enact an inventive and often animistic “performative realism” (Ingawanij 2013a) which can be understood as political in the sense that it creates new conditions of possibility and room for alter-ontologies. The article conceptualizes this orientation in relation to the production of “assemblages of collective enunciation” (Deleuze and Guattari 1986) as well as to Eduardo Viveiros de Castro’s (2010) idea of “taking seriously” the ontology of others, that is, the other worlds that they experience

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Photography, Anthropology of

This entry charts the emergence of the anthropology of photography as a distinctive strand of recent anthropological inquiry, contextualizing the initial intellectual impetus for it and the academic contexts within which it emerged; describes the major areas of inquiry to date, as well as key areas of current research and theory, and the changing landscape of the study in the context of rapid social and technological change; and provides an overview of likely future areas of ethnographic and theoretical investigation. The two key strands of the anthropology of photography are discussed, namely the study of photographs as historical documents and as sources for new types of anthropological history writing, and the ethnographic study of indigenous photographic cultures, set within local and global visual systems of communication

A unique dual activity amino acid hydroxylase in Toxoplasma gondii.

The genome of the protozoan parasite Toxoplasma gondii was found to contain two genes encoding tyrosine hydroxylase; that produces L-DOPA. The encoded enzymes metabolize phenylalanine as well as tyrosine with substrate preference for tyrosine. Thus the enzymes catabolize phenylalanine to tyrosine and tyrosine to L-DOPA. The catalytic domain descriptive of this class of enzymes is conserved with the parasite enzyme and exhibits similar kinetic properties to metazoan tyrosine hydroxylases, but contains a unique N-terminal extension with a signal sequence motif. One of the genes, TgAaaH1, is constitutively expressed while the other gene, TgAaaH2, is induced during formation of the bradyzoites of the cyst stages of the life cycle. This is the first description of an aromatic amino acid hydroxylase in an apicomplexan parasite. Extensive searching of apicomplexan genome sequences revealed an ortholog in Neospora caninum but not in Eimeria, Cryptosporidium, Theileria, or Plasmodium. Possible role(s) of these bi-functional enzymes during host infection are discussed
