While still in the midst of their study abroad experiences, students at Linfield College write reflective essays. Their essays address issues of cultural similarity and difference, compare lifestyles, mores, norms, and habits between their host countries and home, and examine changes in perceptions about their host countries and the United States. In this essay, Stacey Strovink describes her observations during her study abroad program at Kanto Gakuin University in Yokohama, Japan
Total reaction cross sections from 141Pr(,)Pr elastic scattering and -induced reaction cross sections at low energies
Elastic scattering data for Pr(,)Pr have been
analyzed to derive a new energy-dependent local potential for the
Pr- system. This potential is used successfully to predict the
cross section of the Pr(,n)Pm reaction at low energies
where new experimental data have become available very recently. Contrary to
various global potentials, this new potential is able to reproduce
simultaneously elastic scattering data around and above the Coulomb barrier and
reaction data below the Coulomb barrier for the Pr- system.
Reasons for the partial failure of the global potentials are explained by
intrinsic properties of the scattering matrix and their variation with energy.
The new local potential may become the basis for the construction of a new
global -nucleus potential.Comment: 12 pages, 8 figures, Phys. Rev. C, accepte
Teaching Agricultural Policy Using Games: The Agripol Game
We developed the AGRIPOL game as a tool for teaching agricultural policy to economic and non-economic students. AGRIPOL consists of a world with 7 different countries, each one represented by a small group of students. The students have to maximize their country's social welfare by choosing an optimal set of policy instruments. By doing this students learn in an interesting and hands-on way to understand the workings of agricultural policy instruments, the interrelatedness between countries (policy impact spill-overs) and the role of political weights in the policy formation process. A WTO negotiation round is included to let students experience the difficulties and benefits of cooperation.economics education, political economy, agricultural policy, Teaching/Communication/Extension/Profession, A2, P16, Q18,
Relativistic Mean Field in 80 nuclei and low energy proton reactions
Relativistic Mean Field calculations have been performed for a number of
nuclei in mass 80 region. Ground state binding energy, charge radius
and charge density values have been compared with experiment. Optical potential
have been generated folding the nuclear density with the microscopic nuclear
interaction DDM3Y. S-factors for low energy () and () reactions
have been calculated and compared with experiment.Comment: To appear in Physical Review
Alpha-particle optical potential proofs at astrophysically relevant energies
and ,n) reaction cross sections recently measured
close to the reaction thresholds are rather well described by a previously
developed regional optical potential. Thus, particular features of the
-particle optical potential at energies below the Coulomb barrier,
besides parameters describing -particle elastic scattering at higher
energies are confirmed. Additional limitations of similar statistical model
calculations for minor reaction channels are shown to be most likely due to an
overlooked process or critical values of statistical model parameters around
closed nuclear shells.Comment: 4 pages, 3 figure
