The Ubiquitous Middle: Conceptualizing Mid-Level Experience in Student Affairs

til very recently, research and writing on mid-level student affairs practitioners focused narrowly on job satisfaction (Scott, 1978; Sagaria, 1986; Bogenschutz and Sagaria, 1988). This article, a scholarly personal narrative, discusses the career track and experiences of mid-level practitioners. The author proposes and discusses suggestions with regard to support for mid-level practitioners and ways of developing our thinking about these positions and professionals

Long-Run Equilibrium Modeling of Alternative Emissions Allowance Allocation Systems in Electric Power Markets

A question in the design of carbon dioxide trading systems is how allowances are to be initially allocated: by auction, by giving away fixed amounts, or by allocating based on output, fuel, or other decisions. The latter system can bias investment, operations, and pricing decisions, and increase costs relative to other systems. A nonlinear complementarity model is used to investigate long-run equilibria that would result under alternative systems for power markets characterized by time varying demand and multiple generation technologies. Existence of equilibria is shown under mild conditions. Solutions show that allocating allowances to new capacity based on fuel use or generator type can distort generation mixes, invert the operating order of power plants, and inflate consumer costs. The distortions can be smaller for tighter CO2 restrictions, and are somewhat mitigated if there are also electricity capacity markets or minimum-run restrictions on coal plants

Faltings heights of abelian varieties with complex multiplication

Let M be the Shimura variety associated with the group of spinor similitudes of a rational quadratic space over of signature (n,2). We prove a conjecture of Bruinier-Kudla-Yang, relating the arithmetic intersection multiplicities of special divisors and big CM points on M to the central derivatives of certain $L$-functions. As an application of this result, we prove an averaged version of Colmez's conjecture on the Faltings heights of CM abelian varieties.Comment: Final version. To appear in Annals of Mat
