Setting the Standards: Examining Research Productivity Among Academic Urologists in the USA and Canada in 2019.
BACKGROUND: Research productivity among academic urologists is strongly encouraged, but little data are available on productivity metrics within the field.
OBJECTIVE: To provide the first comprehensive survey of research productivity among academic urologists in the USA and Canada.
DESIGN, SETTING, AND PARTICIPANTS: Using the Accreditation Council for Graduate Medical Education, the Canadian Resident Matching Service, and individual program websites, all active accredited urology faculties were identified. For each individual, we collected data on American Urological Association section, title, gender, fellowship training, Scopus H-index, and citations. Comprehensive searches were completed during March-May 2019.
OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Descriptive statistics for demographic comparisons were performed using analysis of variance for continuous variables and chi-square test for categorical variables. Multivariable logistic regressions were used to identify the predictors of H-index greater than the median.
RESULTS AND LIMITATIONS: A total of 2214 academic urology faculties (2015 in USA and 199 in Canada) were identified. The median and mean H-indices for the entire cohort of physicians were 11 and 16.1, respectively. On multivariable analysis, physicians in the North Central and Western Sections (vs mid-Atlantic), who were fellowship trained (vs no fellowship training), and of higher academic rank (professor and associate professor vs clinical instructor) were more likely to have H-index values greater than the median. Additionally, female physicians (vs male) were more likely to have H-index values less than the median.
CONCLUSIONS: This study represents the first comprehensive assessment of research productivity metrics among academic urologists. These represent key benchmarks for trainees considering careers in academics and for practicing physicians gauging their own productivity in relation to their peers.
PATIENT SUMMARY: In this study, we provide the first comprehensive assessment of research productivity among academic urologists in the USA and Canada. Our results help provide key benchmarks for trainees considering careers in academics and for practicing physicians gauging their own productivity in relation to peers
LSST: from Science Drivers to Reference Design and Anticipated Data Products
(Abridged) We describe here the most ambitious survey currently planned in
the optical, the Large Synoptic Survey Telescope (LSST). A vast array of
science will be enabled by a single wide-deep-fast sky survey, and LSST will
have unique survey capability in the faint time domain. The LSST design is
driven by four main science themes: probing dark energy and dark matter, taking
an inventory of the Solar System, exploring the transient optical sky, and
mapping the Milky Way. LSST will be a wide-field ground-based system sited at
Cerro Pach\'{o}n in northern Chile. The telescope will have an 8.4 m (6.5 m
effective) primary mirror, a 9.6 deg field of view, and a 3.2 Gigapixel
camera. The standard observing sequence will consist of pairs of 15-second
exposures in a given field, with two such visits in each pointing in a given
night. With these repeats, the LSST system is capable of imaging about 10,000
square degrees of sky in a single filter in three nights. The typical 5
point-source depth in a single visit in will be (AB). The
project is in the construction phase and will begin regular survey operations
by 2022. The survey area will be contained within 30,000 deg with
, and will be imaged multiple times in six bands, ,
covering the wavelength range 320--1050 nm. About 90\% of the observing time
will be devoted to a deep-wide-fast survey mode which will uniformly observe a
18,000 deg region about 800 times (summed over all six bands) during the
anticipated 10 years of operations, and yield a coadded map to . The
remaining 10\% of the observing time will be allocated to projects such as a
Very Deep and Fast time domain survey. The goal is to make LSST data products,
including a relational database of about 32 trillion observations of 40 billion
objects, available to the public and scientists around the world.Comment: 57 pages, 32 color figures, version with high-resolution figures

Navigating a river by its bends. A study on transnational social networks as resources for the transformation of Cambodia
This article explores in what ways first generation Cambodian French and Cambodian American returnees create and employ the social capital available in their transnational social networks upon their return to Cambodia. The triangular interdependence between the returnees, their overseas immigrant communities and homeland society is taken as a starting point. The central argument is that Cambodian French and Cambodian American returnees build different relationships to Cambodia due to: (1) the influence of their immigrant communities in the countries of resettlement; and (2) the contexts of their exit from Cambodia. Regarding debates on the contribution of returnees to an emergent nation, findings in this multisited casestudy bring forward that ideas of return held by the three parties involved may force remigrants into transnationalism in both host and home countries. Findings also demonstrate that social capital may be seen as a resource or a restraint in the lives of returnees
Screening and Surveillance for the Early Detection of Colorectal Cancer and Adenomatous Polyps, 2008: A Joint Guideline From the American Cancer Society, the US Multi-Society Task Force on Colorectal Cancer, and the American College of Radiology
In the United States, colorectal cancer (CRC) is the third most common cancer diagnosed among men and women and the second leading cause of death from cancer. CRC largely can be prevented by the detection and removal of adenomatous polyps, and survival is significantly better when CRC is diagnosed while still localized. In 2006 to 2007, the American Cancer Society, the US Multi-Society Task Force on Colorectal Cancer, and the American College of Radiology came together to develop consensus guidelines for the detection of adenomatous polyps and CRC in asymptomatic average-risk adults. In this update of each organizationâs guidelines, screening tests are grouped into those that primarily detect cancer early and those that can detect cancer early and also can detect adenomatous polyps, thus providing a greater potential for prevention through polypectomy. When possible, clinicians should make patients aware of the full range of screening options, but at a minimum they should be prepared to offer patients a choice between a screening test that primarily is effective at early cancer detection and a screening test that is effective at both early cancer detection and cancer prevention through the detection and removal of polyps. It is the strong opinion of these 3 organizations that colon cancer prevention should be the primary goal of screening
