found to be a minor component of amyloid plaques in Alzheimer's disease [19]. Alternatively, it is possible that there is an inhibitor of prion generation and propagation whose activity is inhibited by an excess of another prion. Excess Hsp104p cures [PSI + ] [20], excess Ydj1p (an Hsp40) can cure [URE3] [21], and Sis1p (another Hsp40) cures [RNQ + ] [22]. Overexpression of Ssb members of the H...

The Puzzle of Falling Enrolments in Physics and Chemistry Courses: Putting Some Pieces Together

This paper reports and discusses the principal findings of an Australian study exploring the decisions of high achieving Year 10 students about taking physics and chemistry courses (Lyons, 2003). The study used a Fmultiple worlds_ framework to explore the diverse background characteristics that previous quantitative research had shown were implicated in these decisions.

Global Investing, Slicing the World Into Meaningful Pieces

This article shows that the active return distributions based on industry modeling are more stable than those based on country modeling. The superior stability of the active returns available to industry modeling comes from the fact that skewness in both the market capitalization and the number of names is much less pronounced across industries than across countries.

The World Distribution of Income: Falling Poverty And... Convergence, Period(*)

We estimate the WDI by integrating individual income distributions for 138 countries between 1970 and 2000. Country distributions are constructed by combining national accounts GDP per capita to anchor the mean with survey data to pin down the dispersion. Poverty rates and headcounts are reported for four specific poverty lines. Rates in 2000 were between one-third and one-half of what they wer...
