A committee created a fictitious author, Ian Mitroff, who published a paper that violated scientific guidelines. The Mitroff paper recommended an advocacy strategy for scientific research; it said that scientists should vigorously defend their initial hypothesis. I use the advocacy strategy to scientifically prove that Mitroff does not exist. Comments Postprint version. Published in Academy of ...
Stability of efficient networks is studied by applying cooperative game theory to a three-node system. Conditions are sought which ensure the existence of a core to the corresponding welfare game. I depart from existing literature by examining three cases that capture features common to communication and transportation industries: (i) nonseparable economies of network integration, (ii) realisti...
Infection of the hepatobiliary system is most commonly due to enteric bacteria. We report three unusual cases of acute cholecystitis in which Staphylococcus aureus was the primary pathogen. Infection of the gallbladder with this organism has been rarely described and may be associated with gallstones and obstructive disease as well as acalculous cholecystitis in the setting of staphylococcal ba...
The fundamental matrix is a two-view tensor that plays a central role in Computer Vision geometry. We address its robust estimation given correspondences between image features. We use a nonparametric estimate of the distribution of image features, and then follow a probabilistic approach to select the best possible set of inliers among the given feature correspondences. The use of this percept...
Objective: To isolate the bacteria in Device associated infections (DAI) and assess their sensitivity patterns in Intensive Care Units of Services Hospital, Lahore from January to December 2010. Materials & methods: This cross-sectional study was carried out on bacterial isolates from samples of devices from various Intensive Care Units of Services Hospital Lahore in the Microbiology section, D...
BACKGROUND While dietary fat has been established as a risk factor for colorectal cancer (CRC), associations between fatty acids (FAs) and CRC have been inconsistent. Using Mendelian randomisation (MR), we sought to evaluate associations between polyunsaturated (PUFA), monounsaturated (MUFA) and saturated FAs (SFAs) and CRC risk. METHODS We analysed genotype data on 9254 CRC cases and 18,386 ...
Research support from the Sol Snider Center for Entrepreneurship at the Wharton School, University of Pennsylvania and the Division of Research, Harvard Business School is gratefully acknowledged. We have benefited from the comments of seminar participants at the Dallas ORSA/TIMS Meeting; Graduate School of Business, University of Chicago; Sloan School of Management, MIT; Anderson School of Man...
Urban air background concentrations of benzene, toluene, ethylbenzene, and xylenes (BTEX) were measured in 2007 in the Tricity area (Gdansk, Gdynia, and Sopot) and Tczew applying two types of passive samplers: Home-made permeation passive samplers and two diffusive passive samplers Orsa 5 (National Dräger) and Radiello (FS Maugeri). Differences between the time-weighted annual averages concentr...
The E test (AB Biodisk NA Inc.) was compared with standard reference methods using the National Committee for Clinical Laboratory Standards's recommendations for determining the MICs of four selected antibiotics against 208 clinical isolates of gram-positive bacteria. These bacteria included 32 strains of Streptococcus pneumoniae, 25 strains of Enterococcus faecium, 20 strains of oxacillin-sens...
As part of the SENTRY antimicrobial surveillance program, we examined the prevalence rates, types, and antibiograms of oxacillin-resistant Staphylococcus aureus from hospitalized patients from 17 institutions in eight countries in Asia-Pacific and South Africa (APAC). From April 1998 to December 1999, a total of 1,711 isolates of S. aureus (814 from blood, 392 from the respiratory tract, 467 fr...
