Getting the Haves to Come out Behind: Fixing the Distributive Injustices of American Health Care

Hyman criticizes an article by Havighurst and Richman regarding the distributive injustices of US health care. Hyman also offers a guide for implementing policy reforms based on the analysis by Havighurst and Richman

The Massachusetts Health Plan: The Good, the Bad, and the Ugly

In spring 2006, Massachusetts enacted legislation to ensure universal health insurance coverage to all residents. The legislation was a hybrid of ideas from across the political spectrum, promoted by a moderately conservative Republican governor with national political aspirations, and passed by a liberal Democratic state House and Senate. Groups from across the political spectrum supported the plan, from the Heritage Foundation on the right to Families USA on the left, although the plan had detractors from across the political spectrum as well. This study briefly describes the basic structure of the Massachusetts plan and identifies the good, the bad, and the ugly. Although the legislation, as Stuart Altman put it, "is not a typical Massachusetts -- Taxachusetts, oh -- just -- crazy -- liberal plan," there is enough "bad" and "ugly" in the mix to raise serious concerns, particularly when the desire to overregulate the health insurance market appears to be hard -- wired into Massachusetts policymakers' DNA. If we want to make health insurance more affordable and avoid the "bad" and the "ugly" of the Massachusetts plan, Congress -- or, barring that, individual states -- should consider a "regulatory federalism" approach. Under such an approach, insurers and insurance purchasers would be required to subject themselves to the laws and regulations of a single state but allowed to select the state. As with corporate charters, this system would allow employers and insurers to select the regulatory regime that most efficiently and cost -- effectively matches the needs of their risk pools. The ability of purchasers and insurers to exit from the state's regulatory oversight (taking their premium taxes with them) would temper opportunistic behavior by legislators and regulators, including the temptation to impose inefficient mandates and otherwise overregulate

Comment on ``Density Matrix Renormalization Group Study of the Haldane Phase in Random One-Dimensional Antiferromagnets"

In a recent Letter (PRL 83, 3297 (1999)), Hida presented numerical results indicating that the Haldane phase of the Heisenberg antiferromagnetic spin-1 chain is stable against bond randomness, for box distributions of the bond strength, even when the box distribution stretches to zero bond strength. The author thus concluded that the Haldane phase is stable against bond randomness for any distribution of the bond strength, no matter how broad. In this Comment, we (i) point out that the randomness distributions studied in this Letter do not represent the broadest possible distributions, and therefore these numerical results do not lead to the conclusion that the Haldane phase is stable against any randomness; and (ii) provide a semiquantitative estimate of the critical randomness beyond which the Haldane phase yields to the Random Singlet phase, in a specific class of random distribution functions for the bond strength.Comment: A comment on PRL 83, 3297 (1999).

Integrating Spatial Working Memory and Remote Memory: Interactions between the Medial Prefrontal Cortex and Hippocampus

In recent years, two separate research streams have focused on information sharing between the medial prefrontal cortex (mPFC) and hippocampus (HC). Research into spatial working memory has shown that successful execution of many types of behaviors requires synchronous activity in the theta range between the mPFC and HC, whereas studies of memory consolidation have shown that shifts in area dependency may be temporally modulated. While the nature of information that is being communicated is still unclear, spatial working memory and remote memory recall is reliant on interactions between these two areas. This review will present recent evidence that shows that these two processes are not as separate as they first appeared. We will also present a novel conceptualization of the nature of the medial prefrontal representation and how this might help explain this area’s role in spatial working memory and remote memory recall
