New Features in FormCalc 4
FormCalc is a Mathematica package for the automatic computation of tree-level
and one-loop Feynman amplitudes. It accepts diagrams generated by FeynArts,
simplifies them, and generates a complete Fortran code for their numerical
evaluation. Version 4 includes new features which enhance performance,
convenience of use, and modularity/code reusability.Comment: 5 pages, Talk given at the 7th DESY Workshop On Elementary Particle

News from FormCalc and LoopTools
The FormCalc package automates the computation of FeynArts amplitudes up to
one loop including the generation of a Fortran code for the numerical
evaluation of the squared matrix element. Major new or enhanced features in
Version 5 are: iterative build-up of essentially arbitrary phase-spaces
including cuts, convolution with density functions, and uniform treatment of
kinematical variables. The LoopTools library supplies the one-loop integrals
necessary for evaluating the squared matrix element. Its most significant
extensions in Version 2.2 are the five-point family of integrals, and complex
and alternate versions.Comment: 5 pages, to appear in the proceedings of the 7th International

Implementation of the MSSM Higgs-mass corrections in
We describe the implementation of the two-loop Higgs-mass corrections of
in the complex MSSM in .
The program for the calculation is included in and documented
here in some detail such that it can be re-used as a template for similar
calculations.Comment: 12 pages, 1 figur
Interest rate expectations and the slope of the money market yield curve
An examination of the relationship between yield and maturity in the money market. The expectations theory suggests that the yield curve should be a good predictor of future spot interest rates. A substantial body of research in recent years has tested this implication of the theory and discussed possible reasons for the lack of support for the theory from these tests. This paper provides a review of this literature.Interest rates
The Relationship of Participation in Service Learning Courses with Alumni Civic-Mindedness and Effectiveness Working with Diversity
Analysis of data from the 2014 IUPUI Alumni survey found that undergraduate alumni who participated in service learning courses reported higher levels of civic-mindedness than alumni who did not participate or participated less often in service learning courses. These results were significant after adjusting for gender, ethnicity, volunteer service in high school, and four high impact practices - participation in study abroad, research with faculty, practicum, and co-curricular service. High school volunteer service, practicum, and co-curricular service were also independent predictors of civic–mindedness. Alumni who participated in service learning courses also reported higher levels of effectiveness working with people of different races, ethnicities and religions
