The Dilettante: The paradox of a professional artist working as an amateur

This research paper presents historic and contemporary examples of artists who produce work that borrows techniques from other professional fields, thus positioning themselves as amateurs in the field from which they are borrowing. This process is examined through exploring the role of artist as dilettante. It proposes that there are various strengths in embracing dilettantism as a strategy, such as within freedom of expression; the provision of an unrestrained research voice; the reinterpretation of tradition without the constraint of traditional rules; the possibility of not knowing and having nothing to loose. Furthermore in relation to my own practice I explore issues of sexual polarity; success and failure; life and death; and personal historic symbolism. Through the lens of the dilettante I explore my practice and working methodology, contextualising it through the practices of artists such as John Baldessari, Mark Dion, Jan Davidsz de Heem, Camille Henrot, Joseph Kosuth, as well as the writings of, Theodor Adorno, Roland Barthes, Brian Eno, Sigmund Freud, Judith Halberstam and Rosalind Krauss

The Impact of Psychostimulants on the Executive Capacities of Children with Attention Deficit Hyperactivity Disorder

The current study compared executive-skill and executive-function deficits resulting from teacher ratings of two clinical groups of students diagnosed with ADHD (ADHD-Med, ADHD-NoMed) with ratings of demographically- matched control groups. In addition, teacher ratings of the ADHD-Med group and the ADHD-NoMed group were compared. The data for both clinical groups and their respective matched control groups were part of the data collected during the standardization of the McCloskey Executive Function Scale – Teacher Report (MEFS-TR). Analyses examined teacher responses to all of the items of the seven Self-Regulation, the Self-Realization, and the Self-Determination Clusters of the MEFS. Congruent with the hypothesis of this study, both clinical groups demonstrated a higher degree of executive dysfunction than that of matched nonclinical groups, particularly within the Academic Arena. Additionally, the ADHD-NoMed group was rated with more deficits than the ADHD-Med group across most self-regulation clusters. Consistent with the hypothesis, a large proportion of deficit ratings for the clinical groups occurred with the Focus, Sustain, Inhibit, and Modulate executive capacities. Multiple other executive capacities were also rated as deficient for both clinical groups within the Engagement, Optimization, Inquiry and Solution Clusters. Overall, the study supported the notion that students diagnosed with ADHD who receive pharmaceutical intervention are most likely to be rated as having executive-function deficits reflecting a lack of knowing when to activate an executive capacity within the Academic Arena and sometimes within the Self/Social Arena, whereas students diagnosed with ADHD who do not receive pharmaceutical intervention are most likely to be rated as having executive-skill deficits and executive-function deficits reflecting a lack of knowing how and when to activate an executive capacity within the Academic Arena, and also frequently within the Self/Social Arena

Healthcare seeking for diarrhoea, malaria and pneumonia among children in four poor rural districts in Sierra Leone in the context of free health care: results of a cross-sectional survey

BACKGROUND: To plan for a community case management (CCM) program after the implementation of the Free Health Care Initiative (FHCI), we assessed health care seeking for children with diarrhoea, malaria and pneumonia in 4 poor rural districts in Sierra Leone. METHODS: In July 2010 we undertook a cross-sectional household cluster survey and qualitative research. Caregivers of children under five years of age were interviewed about healthcare seeking. We evaluated the association of various factors with not seeking health care by obtaining adjusted odds ratios and 95% confidence limits using a multivariable logistic regression model. Focus groups and in-depth interviews of young mothers, fathers and older caregivers in 12 villages explored household recognition and response to child morbidity. RESULTS: The response rate was 93% (n=5951). Over 85% of children were brought for care for all conditions. However, 10.8% of those with diarrhoea, 36.5% of those with presumed pneumonia and 41.0% of those with fever did not receive recommended treatment. In the multivariable models, use of traditional treatments was significantly associated with not seeking outside care for all three conditions. Qualitative data showed that traditional treatments were used due to preferences for locally available treatments and barriers to facility care that remain even after FHCI. CONCLUSION: We found high healthcare seeking rates soon after the FHCI; however, many children do not receive recommended treatment, and some are given traditional treatment instead of seeking outside care. Facility care needs to be improved and the CCM program should target those few children still not accessing care

Ultrasound-Guided Placement of a Renal Artery Stent Using an Intracardiac Probe for Transvascular Imaging

In this set of images obtained during an experimental study using a porcine animal model, we introduce ultrasound guidance of percutaneous transluminal renal angioplasty and renal stenting. A state-of-the-art intracardiac ultrasound catheter is used here for transvascular scanning from within the lumen of the abdominal aorta, thus providing a field of view for navigation of a balloon catheter and a wire coil (“stent”) into each renal artery of a pig. This study is intended as a contribution to the growing field of minimally invasive interventions and their navigation by non-ionizing ultrasound imaging

Synergies, tensions and challenges in HIV prevention, treatment and cure research: exploratory conversations with HIV experts in South Africa

Background: The ethical concerns associated with HIV prevention and treatment research have been widely explored in South Africa over the past 3 decades. However, HIV cure research is relatively new to the region and significant ethical and social challenges are anticipated. There has been no published empirical enquiry in Africa into key informant perspectives on HIV cure research. Consequently, this study was conducted to gain preliminary data from South African HIV clinicians, researchers and activists. Methods: In-depth interviews were conducted on a purposive sample of fourteen key informants in South Africa. Audiotaped interviews were transcribed verbatim with concurrent thematic analysis. The perspectives of HIV clinicians, researchers and activists were captured. Analyst triangulation occurred as the data were analysed by three authors independently. Results: The rapid evolution of HIV cure research agendas was prominent with participants expressing some concern that the global North was driving the cure agenda. Participants described a symbiotic relationship between cure, treatment and prevention research necessitating collaboration. Assessing and managing knowledge and expectations around HIV cure research emerged as a central theme related to challenges to constructing ‘cure’ - how patients understand the idea of cure is important in explaining the complexity of cure research especially in the South African context where understanding of science is often challenging. Managing expectations and avoiding curative misconception will have implications for consent processes. Unique strategies in cure research could include treatment interruption, which has the potential to create therapeutic and ethical conflict and will be perceived as a significant risk. Ethical challenges in cure research will impact on informed consent and community engagement. Conclusions: It was encouraging to note the desire for synergy amongst researchers and clinicians working in the fields of prevention, treatment and cure. Translation of complex HIV cure science into lay language is critical. Moving forward, RECs must be adequately constituted with scientific expertise and community representation when reviewing cure protocols. It is hoped that knowledge and resource sharing in the context of collaboration between research scientists working in cure and those working in treatment and prevention will accelerate progress towards cur

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
