“…not all individuals living in fluoridated areas experienced lower disease rates…”

Caries remains the most prevalent non-contagious infectious disease in humans. It is clear that the current approaches to decrease the prevalence of caries in human populations, including water fluoridation and school-based programs, are not enough to protect everyone. The scientific community has suggested the need for innovative work in a number of areas in cariology, encompassing disease etiology, epidemiology, definition, prevention, and treatment. We have pioneered the work on genetic studies to identify genes and genetic markers of diagnostic, prognostic, and therapeutic value. This paper summarizes a presentation that elaborated on these initial findings.

“Climate change”….a convenient strawman for politicians….not science

Weather changes. Weather variability observed over long periods of time (3 decades or more) characterize climate. The earth’s energy balance is always in dis-equilibrium simply due to the earth’s tilt and rotation, ENSO, and other factors….which affect weather and climate.

Only 36 percent of geoscientists and engineers believe that humans are creating a global warming crisis (primarily modelers, I would guess). A strong majority of the 1,077 respondents believe that nature is the primary cause of recent global warming and/or that future global warming will not be a very serious problem, and rightly so.

Abstract: This paper examines the framings and identity work associated with professionals’ discursive construction of climate change science, their legitimation of themselves as experts on ‘the truth’, and their attitudes towards regulatory measures. Drawing from survey responses of 1077 professional engineers and geoscientists, we reconstruct their framings of the issue and knowledge claims to position themselves within their organizational and their professional institutions. In understanding the struggle over what constitutes and legitimizes expertise, we make apparent the heterogeneity of claims, legitimation strategies, and use of emotionality and metaphor. By linking notions of the science or science fiction of climate change to the assessment of the adequacy of global and local policies and of potential organizational responses, we contribute to the understanding of ‘defensive institutional work’ by professionals within petroleum companies, related industries, government regulators, and their professional association.
