Slavery as a national crime: Defining Britishness in Encounters with the Flying Dutchman

Early British gothic fiction has often been analyzed in terms of the religious, political and cultural oppositions it helps to construct between Britain and the European continent, in particular in Catholic countries like France and Spain. One could argue that the cultural work of Gothic in these cases is to (re)define cultural differences between spaces that are geographically already separate. This division of territorial space is obviously much less clear at sea, and so this raises the question if and how national boundaries and identities are being upheld and transgressed in nautical Gothic. The figure of the Flying Dutchman, the ghostly captain doomed to sail the world seas forever, provides and interesting case study for exploring this issue of constructing such national identities. Nineteenth century British culture demonstrates a persistent preoccupation with the ghostly Dutchman. Numerous adaptations and manifestations of the Dutchman in British poetry, fiction, popular song and drama attest to the often problematic ‘Doppelgänger dilemmas’ (Rubright) the Flying Dutchman presents to a British audience: part of his frightening quality is that he is too close for comfort. In my article I will analyze representations of the Flying Dutchman in two British dramas (Fitzball & Taylor), a novel (Marryat), as well as some British poems and songs (1820-1860) in connection to encounters at sea and in the colonies. I will argue that in British nautical gothic the Flying Dutchman often serves as a projection screen for racist attitudes and pro-slavery opinions, but that British characters in these texts do not always succeed in warding off these attitudes

An evaluation of the density functional approach in the zero order regular approximation for relativistic effects: Magnetic interactions in small metal compounds

The density functional approach was evaluated for electron spin resonance (ESR) parameters in the relativistic zero order regular approximation in small metal compounds. The effects of spin-orbit coupling and spin polarization on the magnetic hyperfine interaction were investigated. It was shown that relativistic effects in the calculation of the hyperfine parameters were large not only for the heavy metals but also for ligands bound to heavy elements due to secondary effects

Side branch healing patterns of the Tryton dedicated bifurcation stent: a 1-year optical coherence tomography follow-up study

The bare-metal Tryton Side Branch (SB) Stent™ (Tryton Medical, Durham, NC, USA) is used with a drug-eluting stent (DES) in the main branch (MB) to treat bifurcation lesions. It is argued that a drug-eluting Tryton-version is needed to improve clinical outcomes, although previous registries have shown good clinical results. More insights in neo-intimal hyperplasia (NIH) growth patterns of the Tryton treatment strategy are needed to decide if and where to drug-coat the stent. Ten patients returned for follow-up angiography (mean follow-up time 393 ± 103 days) and optical coherence tomography (OCT) pullbacks from the MB were obtained in all patients and from the SB in six patients. A per-strut analysis showed an uncovered strut rate of 0.7 % and an incompletely-apposed strut rate of 0.8 %. Most incompletely-apposed struts were found at the bifurcation region, in the luminal half facing towards the SB. Mean NIH thickness in the proximal MB, distal MB and SB were 0.14 ± 0.11, 0.19 ± 0.11, and 0.34 ± 0.19 mm, respectively, with a variety of growth patterns observed in the SB. We found good vascular healing of the DES in the MB, while healing was less favourably in the SB part. Furthermore, we observed a variety of NIH growth patterns in this SB part and more studies are needed to investigate the relation between growth patterns and clinical outcomes

A note on comonotonicity and positivity of the control components of decoupled quadratic FBSDE

In this small note we are concerned with the solution of Forward-Backward Stochastic Differential Equations (FBSDE) with drivers that grow quadratically in the control component (quadratic growth FBSDE or qgFBSDE). The main theorem is a comparison result that allows comparing componentwise the signs of the control processes of two different qgFBSDE. As a byproduct one obtains conditions that allow establishing the positivity of the control process.Comment: accepted for publicatio

How Does Routine Prostate-specific Membrane Antigen Positron Emission Tomography/Computed Tomography Modify the Current Management of Prostate Cancer? A Multidisciplinary View

Background and objective: Prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA-PET/CT) and new treatment modalities have expanded the possibilities for diagnosing and managing metastatic prostate cancer, but have also raised questions about their implementation in daily clinical practice. We sought consensus on definitions, preferred imaging modality for staging, and treatment selection in the era of next-generation imaging. Methods: A modified Delphi method involved two voting rounds and a face-to-face multidisciplinary meeting with 40 Dutch prostate cancer (PCa) experts. Consensus was reached if ≥75% of the panellists chose the same option. Appropriateness was assessed by the RAND Corporation/University of California Los Angeles appropriateness method. Key findings and limitations: There was consensus on performing metastatic screening with PSMA-PET/CT for unfavourable intermediate- or high-risk PCa. PSMA-PET/CT findings were considered feasible for determining treatment in synchronous metastatic hormone-sensitive prostate cancer, but there was no agreement on the validity of the CHAARTED criteria for interpreting the PSMA-PET/CT findings. If the PSMA-PET/CT findings led to upstaging after conventional imaging, 76% of panellists would opt for treatment intensification. In case of downstaging, 71% would choose for deintensification. Panellists would generally treat patients based on metastatic disease volume as per the CHAARTED criteria, except for bulky low-volume disease (LVD) and LVD with multiple (more than ten) bone metastases, all within the axial skeleton. This would be classified as LVD but treated as high-volume disease. Limitations are that the statements are largely consensus based and originate from a national (Dutch) perspective. Conclusions and clinical implications: PSMA-PET/CT was considered the preferred modality for initial PCa staging, which is nowadays the standard of care in The Netherlands. The majority of panellists would incorporate PSMA-PET/CT findings for treatment planning, including intensification and deintensification, but the criteria for interpreting metastatic disease volume on PSMA-PET/CT are still uncertain. Patient summary: A group of Dutch medical specialists discussed on how to diagnose metastatic hormone-sensitive prostate cancer and choose the most appropriate treatment for patients with this condition. It was concluded that imaging based on Prostate-specific membrane antigen (PSMA) positron emission tomography (PET) helps determine appropriate treatment options, with most experts supporting treatment adjustments based on PSMA-PET/computed tomography (CT) results. However, there is still some uncertainty about the criteria for interpreting the extent of metastatic disease with PSMA-PET/CT

Ethical issues at the interface of clinical care and research practice in pediatric oncology: a narrative review of parents' and physicians' experiences

Contains fulltext : 97879.pdf (publisher's version ) (Open Access)BACKGROUND: Pediatric oncology has a strong research culture. Most pediatric oncologists are investigators, involved in clinical care as well as research. As a result, a remarkable proportion of children with cancer enrolls in a trial during treatment. This paper discusses the ethical consequences of the unprecedented integration of research and care in pediatric oncology from the perspective of parents and physicians. METHODOLOGY: An empirical ethical approach, combining (1) a narrative review of (primarily) qualitative studies on parents' and physicians' experiences of the pediatric oncology research practice, and (2) comparison of these experiences with existing theoretical ethical concepts about (pediatric) research. The use of empirical evidence enriches these concepts by taking into account the peculiarities that ethical challenges pose in practice. RESULTS: Analysis of the 22 studies reviewed revealed that the integration of research and care has consequences for the informed consent process, the promotion of the child's best interests, and the role of the physician (doctor vs. scientist). True consent to research is difficult to achieve due to the complexity of research protocols, emotional stress and parents' dependency on their child's physician. Parents' role is to promote their child's best interests, also when they are asked to consider enrolling their child in a trial. Parents are almost never in equipoise on trial participation, which leaves them with the agonizing situation of wanting to do what is best for their child, while being fearful of making the wrong decision. Furthermore, a therapeutic misconception endangers correct assessment of participation, making parents inaccurately attribute therapeutic intent to research procedures. Physicians prefer the perspective of a therapist over a researcher. Consequently they may truly believe that in the research setting they promote the child's best interests, which maintains the existence of a therapeutic misconception between them and parents. CONCLUSION: Due to the integration of research and care, their different ethical perspectives become intertwined in the daily practice of pediatric oncology. Increasing awareness of what this means for the communication between parents and physicians is essential. Future research should focus on efforts that overcome the problems that the synchronicity of research and care evokes

Production of He-4 and (4) in Pb-Pb collisions at root(NN)-N-S=2.76 TeV at the LHC

Results on the production of He-4 and (4) nuclei in Pb-Pb collisions at root(NN)-N-S = 2.76 TeV in the rapidity range vertical bar y vertical bar <1, using the ALICE detector, are presented in this paper. The rapidity densities corresponding to 0-10% central events are found to be dN/dy4(He) = (0.8 +/- 0.4 (stat) +/- 0.3 (syst)) x 10(-6) and dN/dy4 = (1.1 +/- 0.4 (stat) +/- 0.2 (syst)) x 10(-6), respectively. This is in agreement with the statistical thermal model expectation assuming the same chemical freeze-out temperature (T-chem = 156 MeV) as for light hadrons. The measured ratio of (4)/He-4 is 1.4 +/- 0.8 (stat) +/- 0.5 (syst). (C) 2018 Published by Elsevier B.V.Peer reviewe
