Measuring the Impact of a Supplemental Civic Education Program on Students’ Civic Attitude and Efficacy Beliefs
This study examines the impact of Project Citizen Philippines, an extra-classroom civic education program, on its 3rd and 4th year high school participants’ civic attitude and efficacy beliefs. Three hundred forty three participants and 107 non-participants from various public high schools in the Philippines’ National Capital Region were compared on their scores on relevant scales, using the Mann-Whitney U test. Qualitative data was also gathered and analyzed using randomly selected student reflection papers. Findings indicate that project participants scored higher in the efficacy and attitude measures used than non-participants. Passages from the reflection papers lend support to these findings. The results are discussed in relation to other findings in the literature, and in light of the country’s current and planned school-based civic education programs. An implication of the study is the need to promote extra-classroom activities to supplement curriculum-based civic education efforts and to reach as wide a student population as possible, and to systematically evaluate and document such efforts towards providing data in furthering civic education in the Philippines
Zero-bias molecular electronics: Exchange-correlation corrections to Landauer's formula
Standard first principles calculations of transport through single molecules
miss exchange-correlation corrections to the Landauer formula. From Kubo
response theory, both the Landauer formula and these corrections in the limit
of zero bias are derived and calculations are presented.Comment: 4 pages, 3 figures, final version to appear in Phys. Rev. B, Rapid

Measuring Integration and Efficiency in Maize Grain Markets: The Case of South Africa and Mozambique
Price transmission between the South African market and other regional markets is not as straightforward, despite South Africa’s role of a surplus producer for the region. There appears to be a host of local factors that must be taken into account in order to anticipate the likely level of regional food prices. This article assesses the degree of market integration and the speed of price adjustment to spatial price differentials between the SAFEX maize price in South Africa and maize grain and maize meal prices in Maputo, Mozambique. The findings of this study indicate that under certain trading regimes, there is no evidence of a long-run relationship between Mozambican and South African maize grain prices. This implies that any large deviations, within these regimes, which exceed transaction costs, could continue to grow with no tendency towards equilibrium. However, the trade volume data indicates maize grain exports from South Africa into Mozambique in every month except for three within the sample set. Hence, the empirical findings of this paper are unexpected given a simple arbitrage argument. Possible reasons for these findings are highlighted in the article. It is interesting to note that when the same empirical analysis is undertaken for the SAFEX maize prices and maize meal prices in Maputo then there is in fact evidence of a long-run relationship between these prices in a high import regime. These findings are not surprising and are what we would expect since two of the largest milling companies, located in Maputo are responsible for the majority of the volume of maize grain imported into the country from South Africa.price transmission, market integration, cointegration, trade regimes, Crop Production/Industries,
Ising model on nonorientable surfaces: Exact solution for the Moebius strip and the Klein bottle
Closed-form expressions are obtained for the partition function of the Ising
model on an M x N simple-quartic lattice embedded on a Moebius strip and a
Klein bottle for finite M and N. The finite-size effects at criticality are
analyzed and compared with those under cylindrical and toroidal boundary
conditions. Our analysis confirms that the central charge is c=1/2.Comment: 8 pages, 3 eps figure
