Cost-Benefit Analysis of Climate Change: Stern Revisited
No full textThis paper explores the challenges facing orthodox economic approaches to assessing climate control as if it were appraisal of an investment project. Serious flaws are noted in the work of economists with especial attention to the UK Government report by Stern and colleagues. The opinions expressed in this paper are those of the authors and may not be taken to reflect the views CSIRO or the Australian Government.enhanced greenhouse effect, global CBA, Stern Report
Visualisation of quantum evolution in the Stern–Gerlach and Rabi experiments
No full textThe Stern–Gerlach experiment is a seminal experiment in quantum physics, involving the interaction between a particle with spin and an applied magnetic field gradient. A recent article [Wennerström et al., Phys. Chem. Chem. Phys., 2012, 14, 1677–1684] claimed that a full understanding of the Stern–Gerlach experiment can only be attained if transverse spin relaxation is taken into account, generated by fluctuating magnetic fields originating in the magnetic materials which generate the field gradient. This interpretation is contrary to the standard quantum description of the Stern–Gerlach experiment, which requires no dissipative effects. We present simulations of conventional quantum dynamics in the Stern–Gerlach experiment, using extended Wigner functions to describe the propagation of the quantum state in space and time. No relaxation effects are required to reproduce the qualitative experimental behaviour. We also present simulations of quantum dynamics in the Rabi experiment, in which an applied radiofrequency field induces spin transitions in the particle wave

No full textLists the descendants of Isaac Jacob Stern (b. 1788) and Johanette Vogel (b. 1795), who changed their names to Starr when they came to America in 1830. Their surviving children were Wolf (b. 1818, married Hannah Kramer), Abraham (b. 1822, married Henrietta Dinkelspiel), Babette (1826-1914, married Barthardt Rosenthal), Caroline (b. 1828, married Joseph Slaughter), Freda (b. 1831, married Isaac Slaughter), Leopold (b. 1837, married Hananda Goldsmith), Sarah (b. 1840, married Bernhard Kuhn), and Yetta (b. 1841, married Meyer Myers)James C.

E. R. von Stern and the Creation of the Northern Black Sea School of Ancient Archaeology
No full textРассмотрено влияние Э. Р. фон Штерна на формирование школы северопричерноморской античной археологии, где были такие исследователи
как Б. В. Фармаковский, М. Ф. Болтенко и др.Ernst R. von Stern (1859—1924) was one of the
prominent historians of antiquity in the late XIX —
early XX century, who participated in the development of Classic archaeology of the Northern Black Sea region.
The article discusses the role of E. R. von Stern in the creation of the school of Classic archaeology, which
was based on the Novorossiisk University in Odessa and the Odessa Society of History and Antiquities, in
particular the museum of that society, as well as the contribution of E. R. von Stern in education of native
archaeologists and historians. E. R. von Stern, having considerable experience
in teaching, understood the importance of educating young professional personnel. As a result, due to a long
and systematic work, E. R. von Stern was able to create a scientific school of his followers.
Among the students of E. R. von Stern were those who later became well-known scholars, connecting their
lives with history and archaeology. In particular, the scientific career of B. V. Farmakovskyi (1870—1928),
an outstanding archaeologist, a long-term researcher of Olbia, was largely formed thanks to the pedagogical
talent of E. R. von Stern. The most known students of E. R. von Stern, except
B. V. Farmakovskyi, were also M. I. Mandes (1866—1934), E. G. Kagarov (1882—1942) and M. F. Boltenko (1888—1959)

Motion in a Circle
No full textThis lesson plan, authored and curated by David P. Stern, provides an approach to teaching circular motion. It covers uniform circular motion, and the relation of its frequency with the peripheral velocity v, the radius of the circle R, and the rotation period T. The topic of centripetal acceleration is included. This lesson plan is connected to textual resources on the topic. This lesson is part of a large site, "From Stargazers to Starships" that introduces physics through space science and an historical perspective
Likelihood inference for small variance components
No full textIn this paper, we develop likelihood-based methods for making inferences about the components of variance in a general normal mixed linear model. In particular, we use local asymptotic approximations to construct confidence intervals for the components of variance when the components are close to the boundary of the parameter space. In the process, we explore the question of how to profile the restricted likelihood (REML), show that general REML estimates have a lower probability of being on the boundary than maximum likelihood estimates, and show that the likelihood-ratio test based on the local asymptotic approximation has higher power against local alternatives than the likelihood-ratio test based on the usual chi-squared approximation. We explore the finite sample properties of the proposed intervals by means of a small simulation study
