1 Millions of young people in the developing world never achieve two decades of life, let alone seven, and so it is with mixed feelings that Health Promotion International celebrates its 20th birthday this issue. Much has been written and said about the antecedents and milestones of the health promotion phenomenon [e.g. (Catford, 2004)], but what is clear from history is that any rapidly growin...

What do members of the general public know about polar regions, and how much do they care? Who knows or cares? This paper explores data from the General Social Survey (GSS), which in 2006 questioned a representative sample of more than 1800 U.S. adults about their knowledge and opinions concerning polar regions. The polar survey items were modeled on long-running GSS assessments of general scie...

We review the present status of theoretical predictions for both closed (J/ψ) and open heavy quark production in high energy collisions, and their comparisons to experimental data.

This talk summarizes recent progress in top quark physics studies for high energy linear electron-positron colliders as presented at the LCWS2000 Workshop at Fermilab. New results were presented for top pair production at threshold and in the continuum, as well as for top production at γγ colliders.

The transverse polarization (or transversity) distributions ∆T q(x), introduced 20 years ago by Ralston and Soper [1] and studied in more detail in the last decade [2], are one of the three sets of leading-twist quark and antiquark distribution functions – the other two are the momentum distributions q(x) and the helicity distributions ∆q(x). (Note that ∆T q is often called h1). Formally ∆T q i...

A particularly simple confinement scenario [1] is available in the minimal Coulomb gauge. It attributes confinement of color to the long range of the color-Coulomb potential Vcoul(R). This quantity is the instantaneous part of the 4-4 component of the gluon propagator, Dμν(x) ≡ 〈gAμ(x) gAν(0)〉, namely D44(x, t) = Vcoul(|x|)δ(t) +P (x, t). The vacuum polarization term P (x, t) is less singular t...

The motion of quark is studied in a confining bag having central color field. The Dirac equation is solved for a quark in such bag and its energy spectrum is found. It is pointed out the possibility to identify the external color field with the background field of gluon condensation. This makes the received energy spectrum of quark useful for comparison with the energy spectrum of hadrons.
