Future Targets and Multiple Equilibria
Get PDFMultiple Pareto-rankable equilibria may obtain in an overlapping generations model where consumers save to reach a fixed target. Existence and uniqueness conditions are discussed. The model displays excess consumption sensitivity to current income and perfect old-age insurance.Multiple equilibria, saving, overlapping generations, excess sensitivity.
S-duality, triangle groups and modular anomalies in N = 2 SQCD
Get PDFWe study N=2 superconformal theories with gauge group SU(N ) and 2N fundamental flavours in a locus of the Coulomb branch with a Z_N
symmetry. In this special vacuum, we calculate the prepotential, the dual periods and the period matrix using equivariant localization. When the flavors are massless, we find that the period matrix is completely specified by [N/2] effective couplings. On each of these, we show that the S-duality group acts as a generalized triangle group and that its hauptmodul can be used to write a non-perturbatively exact relation between each effective coupling and the bare one. For N = 2, 3, 4 and 6, the generalized triangle group is an arithmetic Hecke group which contains a subgroup that is also a congruence subgroup of the modular group PSL(2,Z). For these cases, we introduce mass deformations that respect the symmetries of the special vacuum and show that the constraints arising from S-duality make it possible to resum the instanton contributions to the period matrix in terms of meromorphic modular forms which solve modular anomaly equations

Development of a new mindset for eLearning Pedagogy: for the Teacher and the Learner
Get PDFTeaching, like learning, involves a personal journey. This researched narrative records the role of technology integration in one instructor’s teaching practice, and examines how literature in the field accounts for ways eLearning technologies have kept the author and her students engaged in the process of learning. Dr. Tara Ashok of the University of Massachusetts Boston chronicles the personal eLearning tool kit she has selected for effective delivery of contents in different teaching formats. She posits the importance of developing a new mindset to adapt to emerging technologies and examines the literature and her own experiences suggesting how and why, eLearning pedagogy must include a focus on the development of a flexible / growth mindset
