Does PAL work? An exploration of affect amongst First-year HE in FE students
The study evaluates a peer-assisted learning (PAL) scheme as an effective strategy in alleviating levels of negative emotions and, in the process, contributes to explorations of affect in first-year students in an HE in FE environment, with a particular focus on anxiety and related emotions. Various types of anxieties are defined in the context of a student’s experience in HE, followed by an explanation of the present interventional study in an HE in FE institution, including the survey method used to collect data analyzed through SPSS. Surprisingly, the main findings are that overall anxiety and worry increased for students belonging to most faculties with time, regardless of participation in the PAL scheme. A positive finding was nonetheless that anxiety levels increased more steadily for students who belonged to the control group. The PAL scheme may have thus influenced how less anxious PAL students felt, compared to those who did not participate in the PAL scheme who were left feeling more anxious at the end of the semester
A List of Wisconsin Springtails With New Records and Annotations (Hexapoda: Parainsecta: Collembola)
Twenty Collembola species new to Wisconsin were collected from soil at two agricultural sites in southern Wisconsin, including an undescribed species of Isotomidae. The state faunal list now contains 52 species representing seven families
Evergreen Leasing of Aquaculture Sites
Government policy on siting of aquaculture must balance the objective of providing a long planning horizon for the industry against a broader social interest of adapting lease terms to new environmental information. Evergreen leases are proposed to balance these objectives. Under an evergreen lease, the lease renewal occurs not at the end of the lease, but rather at midterm. For example, a 20-year lease might be renewed at year five or year 10. The mid-term renewal process avoids end-point biases and also creates incentives for the two parties to successfully bargain a renewal. Evergreen leases are an appropriate institution when two parties want a long-term relationship but recognize that terms of the relationship must evolve to reflect new information.aquaculture, evergreen leases, Resource /Energy Economics and Policy, Q22,
Magnetic studies of the lightly Ru doped perovskite rhodates Sr(Ru,Rh)O
The solid solution between the ferromagnetic metal SrRuO and the enhanced
paramagnetic metal SrRhO was recently reported [K. Yamaura et al., Phys.
Rev. B 69 (2004) 024410], and an unexpected feature was found in the specific
heat data at =0.9 of SrRuRhO. The feature was reinvestigated
further by characterizing additional samples with various Ru concentrations in
the vicinity of =0.9. Specific heat and magnetic susceptibility data
indicate that the feature reflects a peculiar magnetism of the doped
perovskite, which appears only in the very narrow composition range

Progress in resolving charge symmetry violation in nucleon structure
Recent work unambiguously resolves the level of charge symmetry violation in
moments of parton distributions using 2+1-flavor lattice QCD. We introduce the
methods used for that analysis by applying them to determine the strong
contribution to the proton-neutron mass difference. We also summarize related
work which reveals that the fraction of baryon spin which is carried by the
quarks is in fact structure-dependent rather than universal across the baryon
octet.Comment: 8 pages, 4 figures; presented at "The Seventh International Symposium

Updated Analysis of the Mass of the H Dibaryon from Lattice QCD
Recent lattice QCD calculations from the HAL and NPLQCD Collaborations have
reported evidence for the existence of a bound state with strangeness -2 and
baryon number 2 at quark masses somewhat higher than the physical values. A
controlled chiral extrapolation of these lattice results to the physical point
suggested that the state, identified with the famed H dibaryon, is most likely
slightly unbound (by 13 14 MeV) with respect to the
threshold. We report the results of an updated analysis which finds the H
unbound by 26 11 MeV. Apart from the insight it would give us into how
QCD is realized in Nature, the H is of great interest because of its potential
implications for the equation of state of dense matter and studies of neutron
stars. It may also explain the enhancement above the
threshold already reported experimentally. It is clearly of great importance
that the latter be pursued in experiments at the new J-PARC facility.Comment: Invited presentation at APPC12 (12th Asia Pacific Physics

Towards a Principled Representation of Discourse Plans
We argue that discourse plans must capture the intended causal and
decompositional relations between communicative actions. We present a planning
algorithm, DPOCL, that builds plan structures that properly capture these
relations, and show how these structures are used to solve the problems that
plagued previous discourse planners, and allow a system to participate
effectively and flexibly in an ongoing dialogue.Comment: requires cogsci94.sty, psfig.st
