Evidence demonstrates that annual screening with gFOBT as well as 1-time and every 3 to 5-year flexible sigmoidoscopy or colonoscopy, reduces colorectal cancer deaths Flexible sigmoidoscopies combined with annual FIT may serve as an alternative to colonoscopy, which is lengthier and more invasive

Fieldwork is an integral component of learning science, but is often overlooked while performing laboratory research. During the summer, a community outreach project for undergraduate students to learn about exposure to heave metals was developed. Together with 12 undergraduate students and faculty who are members of the Rutgers Environmental and Occupational Health Sciences Institute, we selected and visited four sampling sites in Trenton, NJ, a community that has long industry history and concerns regarding the consequences of heavy metal contamination. The purpose of this Frontiers in Physiology Research Teacher activity was to evaluate soil and street dust levels of lead (Pb), which affects the central nervous system and may lead to development delays in children. Four teams of students, postdocs, teachers (high school and middle school) and a member of Isles, Inc., a New Jersey based community development and environmental organization collected street dust and soil at a former smelter, an abandoned park and children playground. Each team kept field notes on sample characteristics and drew maps of each sample location with proximity to roads, schools, and public parks. Upon return to the laboratory, samples of street dust and soil were dissolved in acids, vented, centrifuged, and microwaved to extract heavy metals. ICP‐MS analysis revealed widespread elevated Pb levels (>125 ppm) above naturally occurring levels (~10–50 ppm) throughout the study region. Mean Pb levels in soil were 155 ppm (range: 19–566 ppm, n=24) and dust, 125 ppm (range: 14–533 ppm, n=22). The highest levels of Pb (>500 ppm) were observed in in land around the former Magic Marker/Philco Battery site. Participants rated the activity highly (mean rating = 4.0, SD 0.6) on a Likert scale of 1–5. Overall, fieldwork provides an opportunity for students and teachers to participate in relevant research and assist a community.Support or Funding InformationSupported by the APS, SOT Intern Program, R25ES020721, P30ES005022, and T32007148This abstract is from the Experimental Biology 2019 Meeting.

Current construction cost indices typically are derived by applying national weights to local costs for materials and labor. In this study, construction cost indices are developed that are based on actual contractor tenders for projects. As such, they incorporate full variation in factor proportions, as well as factor costs, contractor overhead, and profit. Cost indices are produced for two product types, office and multi-family residential, in six different MSAs using F.W. Dodge project cost data from 1967 through the first half of 2004. Standard “hedonic” analysis is applied to control for variation in project scale and features to extract the true time trends in costs for each market. The findings indicated that real construction costs generally have fallen slightly over the last 35 years. In addition, no correlation is found between costs and building activity. Causal (IV) analysis implies that the construction industry is elastically supplied to local real estate markets, with any “excess” profits going to land and developer entrepreneurship. This is consistent with the traditional “urban land economics” literature.

Qu’est-ce qui décide d’une vocation ? Qu’est-ce qui, dans une enfance, oriente un destin ? Telles sont les questions qui servent de fil rouge au beau livre de Marie-Isabelle Merle des Isles, qui s’ouvre et se clôt sur l’évocation des travaux picturaux et scientifiques de Jean Rouch. Ethnologue et cinéaste, mais aussi photographe et dessinateur de talent, celui-ci avait reçu, à l’origine, une formation d’ingénieur du génie civil et rien, dans son orientation professionnelle, ne le destinait à ...
