Successful sales people are competent communicators (Williams & Spiro, 1985) who have the knowledge, skill, and motivation to interact effectively and appropriately (Spitzberg & Cupach, 1984) in sales situations. Through [...]

An interview with photographer Craig Smith about taking pictures of physical evidence from crime scenes is presented. He says that his first concerns centered on avoiding to turn the work into some diatribe about gun control. He shares his views on whether photography is an appropriate medium to address issues of violence. Smith notes the difficulty in making a comment about the ideas surrounding violence in culture to some people who work with it every day.

The article features photographers Tina Modotti and Edward Weston, who have familiarized themselves with Mexican art. Both artists have embraced the spirit of Mexican nationalism in their works. Although the two photographers are known to work hand in hand, their different beliefs on socio-political life are the result of their chasm. Modotti's interest in photography was influenced by Weston, whom she considers as an excellent teacher.

An interview with filmmaker Stan Brakhage is presented. He mentions some of the initial sources of his religious and spiritual interests in filmmaking. He explains his notion that all art should aspire to the condition of music. He considers the obligation of society to nurture artists. He mentions his requirements for the presentations of his films.

In common with most recent investigators, we assume that olivine in the upper mantle goes through a phase change to spinel. Spinel at higher pressures breaks down to a post-spinel phase, possibly a mixture of the oxides, periclase and stishovite. We have constructed melting curves of olivine, spinel and periclase and assume that these are the highest melting phases at the various depths in the mantle. Thus, melting curves of these three phases represent the upper limit of the liquidus of the mantle. The solidus of the mantle at low pressures is at a temperature approximately 900° below the liquidus. We have attempted to evaluate the effect of pressure on eutectic minima and thus construct the solidus of the mantle. Our estimated temperature of beginning of melting at the core mantle boundary is circa 3600°. We suggest that most of the mantle at depths greater than a few hundred kilometers is close to or at its solidus temperature and that this temperature controls the temperature of the core of the earth and thus regulates the size of the inner core of the earth. We also note that our estimated temperature gradient of the earth lies very close to the adiabatic gradient for most of the deeper parts of the mantle and thus convection in the mantle is probably restricted to the relatively shallow upper portions of the mantle.
