Black swans

Angelia Sebok, Christopher D Wickens
OBJECTIVE: The objectives were to (a) implement theoretical perspectives regarding human-automation interaction (HAI) into model-based tools to assist designers in developing systems that support effective performance and (b) conduct validations to assess the ability of the models to predict operator performance. BACKGROUND: Two key concepts in HAI, the lumberjack analogy and black swan events, have been studied extensively. The lumberjack analogy describes the effects of imperfect automation on operator performance...

BACKGROUND: Little is known about the course of depression in midlife women. This study aims to identify factors that distinguish risk factors for persistent or recurrent depression from those of a milder course across 13-years of follow-up. METHODS: 297 Black and White premenopausal women aged 42-52 were enrolled at the Study of Women's Health Across the Nation Pittsburgh site. Psychiatric interviews obtained information on lifetime psychiatric diagnoses at baseline and occurrences of depression annually...

A strain of bacteria was isolated from the diseased black swan (Cygnus atratus) died from enteritis diarrhea, and designated tentatively as B-1 strain. Morphological and biochemical tests, as well as phylogenetic analysis derived from 16S rRNA and fimC gene sequencing both strongly indicated that B-1 strain is identical to Escherichia coli. Furthermore, the polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP) profile of the isolate was different from that of two reference strains. Antibiotic sensitivity testing of B-1 strain was carried out by the standard Kirby-Bauer disc diffusion method...

BACKGROUND: Medication utilization and costs increased over the last decade, but the effects of race/ethnicity have never been well studied in longitudinal data. We analyzed reports of prescription medication use to (1) identify trajectories of use and (2) determine predictors associated with a large increase in use. Specifically, variations in medication use by race/ethnicity were examined. METHODS: We analyzed the Study of Women's Health Across the Nation cohort with a median of 14 years of follow-up...

We report a case of a 50-year-old lady with allergic contact dermatitis to para-phenylenediamine, who in her quest to find a substitute hair dye, subsequently reacted to a number of plant-based hair dyes, including pure henna, black tea and indigo powder respectively. While these substances all contain tannins, testing to possible constituents tannic acid and gallic acid was negative.

An asymptomatic 14-year old, male black swan ( Cygnus atratus ) housed at a zoological institution was presented for routine preshipment examination. Hematologic findings indicated that the bird had a severe lymphocytic leukocytosis, consistent with chronic lymphocytic leukemia. Radiographs showed the presence of multiple soft tissue masses within the caudal coelomic cavity; ultrasound showed one mass to be an enlarged spleen, a cystic mass near the gonads, and a mass suspected to be associated with the ventriculus...

A 3-year-old male black swan (Cygnus atratus), belonging to a private collection, died suddenly and was subjected to post mortem examination. At necropsy, caseous exudate was observed in the lungs and air sacs; granulomatous lesions characterized by epithelioid macrophages and abundant mycobacteria were observed microscopically. Avian tuberculosis associated with Mycobacterium bovis was confirmed by bacteriologic isolation, biochemical tests and molecular methods. The organism was identified as spoligotype SB0140, which is frequently found in cattle and people in North America...

BACKGROUND: Interactions between wildlife and humans are increasing. Urban animals are often less wary of humans than their non-urban counterparts, which could be explained by habituation, adaptation or local site selection. Under local site selection, individuals that are less tolerant of humans are less likely to settle in urban areas. However, there is little evidence for such temperament-based site selection, and even less is known about its underlying genetic basis. We tested whether site selection in urban and non-urban habitats by black swans (Cygnus atratus) was associated with polymorphisms in two genes linked to fear in animals, the dopamine receptor D4 (DRD4) and serotonin transporter (SERT) genes...

INTRODUCTION: Different forms of artistic expression, such as literature and cinema, constitute an inexhaustible source for the study of mental illness. The use of psychodynamic models may contribute to a better understanding of the spectrum between personality disorders and the psychosis spectrum, thus enriching the phenomenological approach in the psychiatric clinical practice. OBJECTIVE: To examine from psychodynamic standpoints the main character of the American film Black Swan, and the nature of her psychotic symptoms...

The present study focuses on the nematode community in the stomachs of three sympatric anatid bird species from the Central Patagonian coast, Argentina. The bird species include the Chubut steamer duck, Tachyeres leucocephalus, the crested duck, Lophonetta specularioides, and the black-necked swan, Cygnus melancoryphus. Up to 138 nematodes representing five species were recovered from 10 of the 13 ducks examined, with an overall prevalence of 77% and a mean intensity of 13.8. Nematodes isolated from the gizzard were Streptocara formosensis and Sciadiocara legendrei (Acuariidae) in T...

Parrott and Koralus argue that a particular cognitive factor--"impaired endogenous question raising"--offers a parsimonious account of three delusion-related phenomena: (1) the development of the Capgras delusion; (2) evidence that patients with schizophrenia outperform healthy control participants on a conditional reasoning task; and (3) evidence that deluded individuals "jump to conclusions". In this response, I assess these claims, and raise my own questions about the "erotetic" theory of delusional thinking...

BACKGROUND: The Total Exposure Study was a stratified, multi-center, cross-sectional study designed to estimate levels of biomarkers of tobacco-specific and non-specific exposure and of potential harm in U.S. adult current cigarette smokers (≥one manufactured cigarette per day over the last year) and tobacco product non-users (no smoking or use of any nicotine containing products over the last 5 years). The study was designed and sponsored by a tobacco company and implemented by contract research organizations in 2002-2003...

Adverse effects of targeted drugs on normal tissues can predict the cancer response. Rash correlates with efficacy of erlotinib, cetuximab and gefitinib and onset of arterial hypertension with response to bevacizumab, sunitinib, axitinib and sorafenib, possible examples of 'Black Swan' events, unexpected scientific observations, as described by Karl Popper in 1935. The proposition is that our patients have individual intrinsic variants of cell growth control, important for tumor response and adverse effects on tumor-unrelated tissue...

The 2014-2015 Ebola virus disease (EVD) epidemic and international public health emergency has been referred to as a "black swan" event, or an event that is unlikely, hard to predict, and highly impactful once it occurs. The Chicago Ebola Response Network (CERN) was formed in response to EVD and is capable of receiving and managing new cases of EVD, while also laying the foundation for a public health network that can anticipate, manage, and prevent the next black swan public health event. By sharing expertise, risk, and resources among 4 major academic centers, Chicago created a sustainable network to respond to the latest in a series of public health emergencies...

The impact of the findings from the Women's Health Initiative trial of estrogen plus progestin cannot be attributed to any real or imagined conflicts of interest between government, researchers, and journals. Rather, the findings overturned decades of dogma in part promoted by the pharmaceutical industry, and the reaction to these unexpected findings was in direct proportion to their importance in reversing a misguided practice of prescribing the drug for chronic disease prevention. The findings have been widely accepted, as shown by the sustained subsequent reduction in prescriptions...

Moderate wine consumption has been associated with reduced cardiovascular (CV) risk, but most investigations have been conducted in Caucasian populations. To investigate the relationship of wine consumption to CV risk markers, we studied a multi-ethnic sample of middle-aged, healthy women (N = 2900; 48% white, 28% black, 7% Hispanic, 8% Chinese, 9% Japanese) participating in SWAN over 7 years with repeated assessments of CV risk factors. Consumption of wine was stable and common with 20% reporting none, 69% light (<1/day), 7% moderate ( = 1/day), and 4% heavy (>1/day)...
