How large is the spreading width of a superdeformed band?

Recent models of the decay out of superdeformed bands can broadly be divided into two categories. One approach is based on the similarity between the tunneling process involved in the decay and that involved in the fusion of heavy ions, and builds on the formalism of nuclear reaction theory. The other arises from an analogy between the superdeformed decay and transport between coupled quantum dots. These models suggest conflicting values for the spreading width of the decaying superdeformed states. In this paper, the decay of superdeformed bands in the five even-even nuclei in which the SD excitation energies have been determined experimentally is considered in the framework of both approaches, and the significance of the difference in the resulting spreading widths is considered. The results of the two models are also compared to tunneling widths estimated from previous barrier height predictions and a parabolic approximation to the barrier shape

TRUSTWORTHINESS AS AN ECONOMIC ASSET

The evaluation of trust in economic decision making remains on the periphery of mainstream economic analysis and teaching. Yet business managers use trustworthiness in daily exchanges to create competitive advantages for their firms. An exploratory empirical test of Barney and HansenÂ’s three levels of trust (weak, semistrong, and strong) and Lewicki and BunkerÂ’s portfolio of governance mechanisms revealed that strong-form trust exists in day-to-day business relationships along with other governance mechanisms. Identity-based transactions were more prevalent than were weak trust market exchanges in important economic transactions.Institutional and Behavioral Economics, International Relations/Trade,

THE INFLUENCE OF DEPRESSIVE SYMPTOMS ON FATHERS’ BEHAVIORS AND ATTITUDES

The present study examines the impact of young, poor, unwed fathers on their family by investigating the influence of depressive symptom frequency on fathers’ relationship with their children and partners. Couples from seven American cities with populations over 200,000 were recruited and interviewed about such areas of life as romantic and parental relationships, health, and employment at the hospital within 24 hours after the birth of their child. An Item Response Theory (IRT) within-group analysis of the 1,759 African-, Caucasian-, Hispanic-, Asian-, and Native American fathers in the study yielded a 3-class clustering of depressive symptoms. Class 1 fathers had the lowest frequency of depressive symptom expression; class 2 fathers had a low frequency; and class 3 fathers had low to medium rates of depressive symptoms. Multivariate statistics revealed that depressive class membership predicted domestic violence toward fathers’ partners but not affection toward their children. The importance of the parental behavior of teaching children about life, however, varied by class, with class 2 fathers most highly endorsing this behavior. Implications of young, unwed, poor fathers' behaviors and attitudes toward their children and romantic partners will be discussed in terms of men's contributions to family life.

Projections and Dyadic Parseval Frame MRA Wavelets

A classical theorem attributed to Naimark states that, given a Parseval frame $\mathcal{B}$ in a Hilbert space $\mathcal{H}$, one can embed $\mathcal{H}$ in a larger Hilbert space $\mathcal{K}$ so that the image of $\mathcal{B}$ is the projection of an orthonormal basis for $\mathcal{K}$. In the present work, we revisit the notion of Parseval frame MRA wavelets from two papers of Paluszy\'nski, \v{S}iki\'c, Weiss, and Xiao (PSWX) and produce an analog of Naimark's theorem for these wavelets at the level of their scaling functions. We aim to make this discussion as self-contained as possible and provide a different point of view on Parseval frame MRA wavelets than that of PSWX.Comment: 19 page
